Description

  The present invention relates to a tonneau cover device for a vehicle installed in a substantially horizontal unfolded position at a position above a cargo compartment at the rear of a vehicle body.

Conventionally, in a vehicle having a back door at the rear of the vehicle body like a station wagon and the front side of which is a luggage compartment space, the cargo in the luggage compartment can be seen from the outside of the vehicle so that it cannot be seen from outside the vehicle. It is known to provide a tonneau cover device that deploys in a direction.
Of course, when the tonneau cover device is present in the upper position of the luggage compartment when the back door is opened and the luggage is taken in and out, it becomes difficult to take in and out the luggage.

  For this reason, as shown in the following Patent Document 1, the tonneau board constituting the tonneau cover device is connected to the back door by a link member or the like, and the rear end of the tonneau board is pulled upward in conjunction with the opening operation of the back door. A tonneau cover device for a vehicle configured as described above is known.

Like the tonneau cover device of this vehicle, by pulling the tonneau board upward in conjunction with the opening operation of the back door, the opening at the rear of the tonneau board is enlarged, and the loading / unloading of the luggage can be facilitated. Convenience can be improved.
Japanese Examined Patent Publication No. 39-16916

  By the way, the luggage compartment at the rear of the vehicle body is configured such that the length in the vehicle width direction (vehicle width length) is narrowed on the upper side as viewed from the rear in accordance with a request for design and the like. For this reason, in the above-mentioned Patent Document 1, in order to avoid interference with the side window etc. on the side surface of the cargo compartment, only the center part of the tonneau board is pulled upward while the both sides in the vehicle width direction of the tonneau board are left in that position. It is composed.

  However, in order to effectively use all the cargo compartments in the vehicle width direction, it is desired to raise the tonneau board in the full width direction.

  Therefore, for example, by providing a guide rail extending in the vertical direction on the rear pillar or the like on the side of the cargo compartment, connecting both sides of the tonneau board to this guide rail, guiding the tonneau board along this guide rail and pulling it upward, It is conceivable to set so that the tonneau board does not protrude outward (rear side). By doing so, the tonneau board can be pulled up with the full width in the vehicle width direction while preventing interference with the side window on the side surface of the cargo compartment.

  However, since the length of the tonneau board does not change, it is necessary to bend the tonneau board forward and follow the guide rail, but it is difficult to always bend the tonneau board in a predetermined direction stably. In particular, considering the ease of folding during storage, if the tonneau board itself does not have a crease in the predetermined folding direction, the tonneau board will bend easily in either direction, resulting in a stable folding direction. Without, the tonneau board may be surely bent and not deformed.

  Therefore, the present invention is a tonneau cover device for a vehicle installed in a substantially horizontal unfolded position at a position above the cargo compartment at the rear of the vehicle body, so that the tonneau board itself can be folded without being bent in the folding direction. An object of the present invention is to provide a tonneau cover device for a vehicle capable of stably pulling up the tonneau board by following the guide rail by ensuring that the tonneau board bends in a predetermined direction while securing the tonneau board. To do.

  A tonneau cover device for a vehicle according to the present invention is a vehicle body rear portion including a back door that covers a vehicle body opening on the rear surface of the vehicle body so as to be openable and closable, and a cargo compartment floor that extends in front of the vehicle body opening, at a position above the cargo compartment floor, In a tonneau cover device for a vehicle installed in a substantially horizontal unfolded state, a pair of left and right guide rails extending in the vertical direction on the left and right side walls of the cargo compartment, and a rear end coupled to the guide rails A board member that extends substantially horizontally above the cargo floor; and a slide drive mechanism that moves the board member up and down along the guide rail. The board member is divided into at least two pieces in the longitudinal direction of the vehicle body. A split board connected in a foldable manner, and when the board member moves up along the guide rail, a predetermined bending deformation occurs between two adjacent split boards. It is provided with a that guide means.

According to the above configuration, when the board member is moved up along the guide rail, the guide means causes a predetermined bending deformation between the two divided boards adjacent to each other.
For this reason, when the board member is moved upward, the guide member always causes a predetermined bending deformation in the board member, and the board member can be reliably bent in a predetermined direction.
Note that the guide means for causing this bending may be provided on the vehicle body side or on the board member side.

In one embodiment of the present invention, the predetermined bending deformation is a mountain bending deformation.
According to the said structure, it sets so that it may deform | transform by a mountain fold deformation between two division boards by a guide means.
For this reason, a board member will bend reliably by a mountain fold deformation | transformation, and the opening part behind a board member can be expanded. In particular, in order to obtain mountain break deformation, it is necessary to set a “trigger” for mountain break. In this case, the rear divided board of the two divided boards is replaced by the front divided board. Must be positioned higher.
For this reason, the division board on the rear side of the board member is positioned at a high position, and the board member is positioned as a “step shape” in which the rear side is positioned upward, improving the appearance of the tonneau cover device in the cargo compartment. it can.
Therefore, it is possible to improve the appearance when the tonneau cover device is deployed while configuring the board member to be bendable.

In one embodiment of the present invention, the guide means is constituted by a support portion that supports the two adjacent divided boards in a mountain-folded state in the unfolded state of the board member.
According to the above configuration, by supporting the two divided boards in the mountain-folded state with the support portion that is the guide means, when the board member moves up, the two divided boards are deformed in the mountain-folded state. be able to.
For this reason, even if the board member itself is not provided with a mechanism for causing mountain breakage, the board member can be surely caused to undergo mountain breakage deformation.
Therefore, the structure of the board member can be configured with a simple structure, and the board member can be manufactured at a low cost and at a low cost.

In one embodiment of the present invention, the rear end of the board member is connected to the guide rail at a position below the plane extension line of the front divided board among the two adjacent divided boards.
According to the above configuration, since the connection position with the guide rail at the rear end of the board member is set at a position below the plane extension line of the front division board among the two division boards, the connection position is When moving forward and obliquely upward along the guide rail, this connecting position becomes a point for pushing the front divided board upward, and the board member can be bent and deformed.
That is, if the connection position is set below the plane extension line of the front division board, a virtual virtual board is set on the straight line connecting the rear end of the front division board and the connection position of the guide rail. Since this virtual board and the front divided board are already in a positional relationship that is bent at a mountain break, moving this connecting position forward causes the mountain break to be bent further. This is because the front divided board is pressed upward.
Therefore, the mountain break deformation of the board member can be promoted, and the mountain break deformation can be surely generated.

In one embodiment of the present invention, the board member is composed of at least three divided boards, and when the board member moves up along the guide rail, the two divided boards adjacent on the rear side of the vehicle body The guide means is set so as to bend in the second direction between two adjacent divided boards on the front side of the vehicle body so as to bend in the first direction.
According to the above configuration, the divided board is configured by at least three, and when the board member moves up along the guide rail, the first direction and the second direction are set between the divided boards by the guide means. In addition, bending deformation occurs in each case.
For this reason, since at least two bending points are formed on the board member, the bending angle between the divided boards and the size and shape of the divided boards themselves can be freely set.
Therefore, it is possible to increase the degree of freedom in designing the board member while reliably generating bending deformation of the board member.
The first direction and the second direction may be completely different directions or the same direction.

In one embodiment of the present invention, at least one front division board is further installed in front of the three division boards.
According to the said structure, the board | substrate member can cover the wider range above a luggage compartment by having installed the front part division board in front of the three division boards.
Therefore, in addition to the three divided board members that expand the rear opening of the board member, the front divided board is further set, so that the wider area above the cargo compartment is covered with the board member while folding The opening behind the board member can be enlarged with a degree of freedom.

In one embodiment of the present invention, the front division board is provided with a fixing portion to the vehicle body side.
According to the above configuration, since the front split board is provided with the fixing portion to the vehicle body side, the board member is fixed to the vehicle body side by the front split board.
For this reason, the position of the board member in the unfolded state is reliably defined by the front divided board which does not participate in the opening enlargement behind the board member.
Therefore, the bending point of the board member is surely defined, and the deformation operation of the board member can be surely caused.

In one embodiment of the present invention, the board member is provided so as to be removable from the vehicle body.
According to the above configuration, since the board member can be removed, the board member can be removed from above the cargo compartment when the board member is not used.
Therefore, when the tonneau cover is not used, the rear luggage space can be widely used, and the luggage space can be expanded.

In one embodiment of the present invention, the board member is configured to be foldable.
According to the above configuration, since the board member can be folded, the large board member can be folded compactly in a state where the board member is detached from the vehicle body in the unfolded state.
Therefore, the board member can be compactly stored in the cargo compartment after being removed, and the board member does not get in the way.

In an embodiment of the present invention, the slide drive mechanism is configured such that the rear end of the board member moves up and down in conjunction with the opening and closing operation of the back door.
According to the above configuration, since the rear end of the board member moves up and down in conjunction with the opening and closing operation of the back door by the slide drive mechanism, the rear end of the board member always moves up and down whenever the back door is opened and closed. Will do.
For this reason, the opening part behind a board member can be expanded only by opening and closing a back door, and the convenience of taking in and out of the luggage | load into a luggage compartment can be improved.
Therefore, the operator can easily take in and out the luggage into the cargo compartment without separately opening and closing only the tonneau cover device.

In one embodiment of the present invention, the slide drive mechanism includes a linear member having one end fixed to the back door and the other end fixed to the rear end of the board member.
According to the above configuration, by including a linear member having one end fixed to the back door and the other end fixed to the rear end of the board member, the slide drive mechanism is configured. The opening / closing operation of the tonneau cover device can be caused mechanically.
Therefore, the opening / closing operation of the back door and the opening / closing operation of the tonneau cover device can be mechanically linked with a simple structure such as a linear member, and the production cost can be reduced.

In one embodiment of the present invention, the slide drive mechanism includes an electric mechanism.
According to the above configuration, since the slide drive mechanism includes the electric mechanism, the tonneau cover device can be freely opened and closed regardless of the opening and closing operation of the back door itself. Moreover, since the opening / closing speed of the tonneau cover device is not restricted by the opening / closing speed of the back door, the tonneau cover device can be freely opened and closed.
Therefore, the tonneau cover device can be freely opened and closed without being restricted by the open / closed state or opening / closing speed of the back door, and the setting of the opening / closing operation of the tonneau cover device can be made free.

According to the present invention, when the board member is moved upward, the guide member always bends and deforms in a predetermined direction by the guide means, and the board member can be reliably bent in a predetermined direction. it can.
Therefore, in a tonneau cover device for a vehicle installed in a substantially horizontal unfolded position above the cargo compartment at the rear of the vehicle body, the board member itself can be easily folded without being bent in the folding direction. However, by configuring the board member to be surely bent in a predetermined direction, the board member can be stably lifted by following the guide rail.

With respect to the fitting groove portion 45 a, The winding unit 31 and the slider member 41 are integrated by fitting the engaging boss portion 36 from above. The fitting groove 45 a is set at an angular position that stands slightly in the vertical direction with respect to the inclination angle of the slide rail 8.

  As shown in FIG. 5, the wire member 42 is set so as to extend vertically in the slide rail 8, the intermediate portion 42 a is fixed to the slider member 41, and the upper end portion 42 b is connected to the first pulley 46. It is fixed to the back door 4 via the second pulley 47, and the lower end portion 42c is connected to the urging means 43 and routed. By arranging the wire member 42 in this way, the slider member 41 can be moved up and down via the wire member 42 in conjunction with the opening / closing operation of the back door 4.

  The aforementioned urging means 43 is constituted by a so-called spiral spring 43a, and always applies a downward urging force to the wire member 42 to give tension to the wire member 42. This urging force is set to a force that does not hinder the opening / closing operation of the back door 4 (a force that is weaker than the assist force of the door opening / closing assist damper 4D (see FIG. 4)). For this reason, even if the urging means 43 is provided, the opening / closing operation of the back door 4 is not deteriorated.

  Next, the opening / closing operation at the time of opening / closing of the tonneau cover device configured as described above will be described with reference to schematic schematic diagrams of FIGS. FIG. 11 is a schematic diagram of a state in which the tonneau cover device is completely closed, FIG. 12 is a schematic diagram of the first stage of the opening process, FIG. 13 is a schematic diagram of the second stage, FIG. 14 is a schematic diagram of the third stage, and FIG. FIG. 16 is a schematic diagram of a fourth stage, and FIG. 16 is a schematic diagram of a state in which the tonneau cover device is completely opened. In addition, about the component of each figure, the code | symbol same as the component demonstrated so far is attached | subjected, and description is abbreviate | omitted.

  As shown in FIG. 11, when the back door 4 is completely closed, since the wire member (not shown) is not pulled up by the back door 4, the slider member 41 is positioned below. For this reason, both the front tonneau cover 20 and the rear tonneau cover 30 are deployed in a substantially horizontal state above the cargo compartment T and completely cover the cargo compartment T.

  In this state, the position of the front tonneau cover 20 is defined by being supported by the shelf 6, and the first board 21 and the second board 22 are in a low position, and the fourth board 24 is in a high position. The three boards 23 are defined at the forwardly inclined position.

  That is, the shelf 6 is formed as a front lower step 61, a rear upper step 62, and a forwardly inclined portion 63 at an intermediate position, so that the front tonneau cover 20 is positioned as a "backward raised step shape". It is prescribed as follows.

  In this way, since the position of the front tonneau cover 20 is defined by the shelf 6, the front tonneau cover 20 described below can be bent.

  On the other hand, the rear tonneau cover 30 is unfolded so that the seat member 32 is pulled out partway and the back door 4 side is slightly downward.

  Next, as shown in FIG. 12, when the back door 4 is slightly opened, the slider member 41 moves slightly upward as the wire member (not shown) is pulled upward. For this reason, the winding unit 31 presses the fourth board 24 upward and forward from the rear, and a fold-down deformation occurs between the front end 24 a of the fourth board 24 and the rear end 23 a of the third board 23.

  As described above, the mountain-fold deformation occurs because the front tonneau cover 20 is supported as a rear-up stepped shape by the shelf 6 described above.

  That is, the fourth board 24 is held at a high position, and the third board 23 is tilted forward and held, so that the fourth board 24 is interposed between the fourth board 24 and the third board 23 as shown in FIG. Has a bending angle α on the lower side. Since the bending direction of the divided board is defined by the bending angle α, the bent portion P having the bending angle α serves as a “trigger” for mountain bending, and mountain bending deformation occurs.

Furthermore, this mountain-fold deformation is also promoted by the position of the engaging boss portion 36 of the winding unit 31, that is, the connecting position (the point of action of the force) with the slider member 41 of the winding unit 31.
That is, as shown in FIG. 11, assuming a dynamic virtual board B on the line connecting the position of the engagement boss 36 and the bent part P, between the virtual board B and the third board 23, The formed bending angle β is further reduced. For this reason, it becomes easier to produce the mountain break deformation in this bending part P, and a mountain break is accelerated | stimulated.

  As described above, the mountain-fold deformation between the fourth board 24 and the third board 23 is determined by the installation angle of the third board 23 and the position of the engagement boss portion 36 of the winding unit 31. It can be seen that the position of the engagement boss portion 36 of the winding unit 31 is set larger and lower than the plane extension line Q extending from the line 23.

  Next, as shown in FIG. 13, when the back door 4 is further opened, the slider member 41 slides to a substantially intermediate position, and the winding unit 31 moves forward and upward. Along with this, the fourth board 24 is pressed forward, and the mountain breakage deformation with the third board 23 further occurs. At this time, valley deformation occurs between the third board 23 and the second board 22, and the displacement of the third board is not hindered.

  At this time, the seat member 32 of the rear tonneau cover 30 to which the back door 4 is fixed follows the opening operation of the back door 4 and is largely pulled out rearward.

  Next, at the opening stage of the back door 4 shown in FIG. 14, the slider member 41 slides further upward, and the winding unit 31 also moves forward and upward. And this winding unit 31 rotates so that an upper part may move ahead by the displacement of the 4th board 24, and the upward pulling of the sheet | seat member 32 (refer arrow).

  Further, the sheet member 32 pulled out from the winding unit 31 is also pulled out backward and upward, and follows the opening operation of the back door 4.

  Further, at the opening stage of the back door 4 shown in FIG. 15, the slider member 41 slides further upward, and the winding unit 31 rotates forward while moving forward and upward. Then, not only the fourth board 24 and the third board 23 but also the second board 22 is displaced upward so that the rear end 22 a of the second board 22 follows the front end 23 a of the third board 23. Be raised.

  Finally, when the back door 4 shown in FIG. 16 is fully opened, the slider member 41 moves to the upper end of the slide rail 8, and the winding unit 31 is positioned at the foremost and uppermost position.

  Then, the front tonneau cover 20 leaves the first board 21 and the other second board 22, third board 23, and fourth board 24 are displaced upward, and the rear tonneau cover 30 has the sheet member 32 as well. It expands greatly upward and expands in a screen shape in a substantially vertical direction.

  In this way, the front tonneau cover 20 enlarges the opening TO at the rear part of the cargo compartment T by the second board 22, the third board 23, and the fourth board 24 being displaced by the mountain fold deformation and the valley fold deformation. This makes it easier to load and unload luggage from the rear. Further, since the sheet member 32 of the rear tonneau cover 30 is developed in a screen shape in a substantially vertical direction, the sheet member 32 does not protrude downward from the inner side surface of the back door 4, and the operator The head member and the sheet member 32 do not interfere with each other.

Next, the function and effect of the present embodiment configured as described above will be described in detail.
In this embodiment, a pair of left and right slide rails 8 extending in the vertical direction on the left and right side walls of the cargo compartment T, and the rear ends of the slide rails 8 are connected to the slide rails 8 so as to be substantially horizontal above the rear floor panel 2. A front tonneau cover 20 that expands to the front and a slide mechanism 40 that moves the front tonneau cover 20 up and down along the slide rail 8. The front tonneau cover 20 is divided into at least two pieces in the longitudinal direction of the vehicle body and bent. When the front tonneau cover 20 moves up along the slide rail 8, the third board 23 and the fourth board 24 that are connected to each other are foldable between the adjacent third board 23 and the fourth board 24. A shelf 6 for causing deformation, specifically, an upper step 62 and an inclined portion 63 are provided.

Thus, when the front tonneau cover 20 is moved up along the slide rail 8, the upper step portion 62 and the inclined portion 63 cause a mountain-fold deformation between the adjacent third board 23 and fourth board 24. become.
For this reason, when the front tonneau cover 20 is moved upward, the upper step portion 62 and the inclined portion 63 always cause the front tonneau cover 20 to bend and deform, so that the front tonneau cover 20 is reliably bent and deformed. It can be bent at.
Therefore, in the tonneau cover device 10 for a vehicle installed in a substantially horizontal unfolded position above the cargo compartment T at the rear of the vehicle body, the front tonneau cover 20 itself can be easily folded without being bent in the folding direction. By ensuring that the front tonneau cover 20 bends in the mountain-folding direction with certainty, the front tonneau cover 20 can be lifted stably following the slide rail 8.

In particular, in this embodiment, it is set so that bending deformation is caused by mountain bending deformation.
That is, in order to set a “trigger” for the mountain break deformation, the fourth board 24 is positioned at a high position, and the third board 23 is positioned so as to be inclined downward in front of it.
For this reason, the front tonneau cover 20 is positioned as a “step shape” in which the rear divided board (24) is higher, so that the appearance of the tonneau cover device 10 in the luggage compartment T can be improved.
Therefore, the appearance in the luggage compartment T can be improved while the front tonneau cover 20 can be bent.

Further, in this embodiment, the adjacent third board 23 and fourth board 24 are supported in a mountain-folded state by the shelf 6 provided on the vehicle body side.
Thereby, when the front tonneau cover 20 moves up, it is possible to cause a mountain-fold deformation between the third board 23 and the fourth board 24.
For this reason, even if the front tonneau cover 20 itself is not provided with a mechanism for causing a mountain break, the front tonneau cover 20 can be surely caused to have a mountain break.
Therefore, the structure of the front tonneau cover 20 can be configured with a simple structure, and the front tonneau cover 20 can be manufactured at a low weight and at a low cost.

In this embodiment, the engaging boss portion 36 of the winding unit 31 is linked to the slider member 41 at a position below the plane extension line Q (see FIG. 11) of the third board 23 of the front tonneau cover 20. Yes.
Accordingly, when the winding unit 31 moves forward and obliquely upward along the slide rail 8, the engagement boss portion 36 serves as a point for pushing up the fourth board 24 from the lower side to the front tonneau cover 20. It is possible to surely cause mountain breakage deformation.
Therefore, the fourth board 24 of the front tonneau cover 20 has a rear end that is pressed from below and moves upward so that the front tonneau cover 20 can be reliably bent and deformed.

Further, in this embodiment, when the front tonneau cover 20 moves up along the slide rail 8, it is set so as to bend in the mountain folding direction between the third board 23 and the fourth board 24 adjacent on the rear side of the vehicle body. The second board 22 and the third board 23 adjacent to each other on the front side of the vehicle body are set so as to be bent in the valley folding direction.
As a result, when the front tonneau cover 20 moves up along the slide rail 8, bending deformation occurs between the boards 22, 23, 24 in the mountain folding direction and the valley folding direction, respectively.
For this reason, at least two folding points are formed on the front tonneau cover 20, so the bending angle between the boards 22, 23, 24, the size of each board 22, 23, 24, The shape etc. can be set freely.
Therefore, the degree of freedom in designing the front tonneau cover 20 can be increased while reliably causing bending deformation of the front tonneau cover 20.
In this embodiment, the folding direction of the front tonneau cover 20 is set to bend in the order of “mountain” and “valley” from the rear side. However, “mountain”, “mountain” and “ The front tonneau cover 20 may be set to be bent at “valley”, “valley”, or “valley” or “mountain”.

In this embodiment, the first board 21 is further installed in front of the second board 22.
Thereby, a wider range above the cargo compartment T can be covered with the front tonneau cover 20.
Therefore, the opening TO at the rear of the front tonneau cover 20 can be expanded with a degree of freedom of bending while covering a wider range above the cargo compartment T with the front tonneau cover 20.

  In this embodiment, the first board 21 is provided with a hinge pin 27a that is a fixed portion to the vehicle body.

Thereby, the first board 21 at the foremost position of the front tonneau cover 20 is always fixed to the vehicle body side when the tonneau cover device 10 is mounted.
For this reason, the position of the front tonneau cover 20 at the time of mounting is reliably defined by the first board 21 not involved in the enlargement of the opening TO at the rear of the cargo compartment T, and the bending point of the front tonneau cover 20 can be reliably defined. .
Therefore, the bending point of the front tonneau cover 20 can be reliably defined while the front tonneau cover 20 and the like can be removed, and the deformation operation of the front tonneau cover 20 can also be reliably caused.

In this embodiment, the front tonneau cover 20 and the rear tonneau cover 30 are removable from the vehicle body.
Thereby, the front tonneau cover 20 and the rear tonneau cover 30 can be removed from the luggage compartment T when the front tonneau cover 20 and the rear tonneau cover 30 are not used.
Therefore, when the tonneau cover device 10 is not used, the cargo space T space can be widely used, and the cargo space can be expanded.

In this embodiment, the front tonneau cover 20 and the rear tonneau cover 30 are configured to be foldable (see FIG. 10).
Thereby, the big tonneau cover apparatus 10 can be folded compactly in the state removed from the vehicle body in the unfolded state.
Therefore, the front tonneau cover 20 and the rear tonneau cover 30 can be compactly stored in the sub trunk portion 2a after being removed, and the front tonneau cover 20 and the rear tonneau cover 30 do not get in the way.

In this embodiment, the slide mechanism 40 is configured to move up and down in conjunction with the opening and closing operation of the back door 4.
Thereby, when the back door 4 is opened and closed, the rear end of the front tonneau cover 20 and the front end of the rear tonneau cover 30 always move up and down.
For this reason, the opening part TO at the rear of the tonneau cover device 10 can be enlarged simply by opening and closing the back door 4, and the loading and unloading of the luggage into the luggage compartment T can be performed easily.
Therefore, the operator can easily put in and out the luggage into the luggage compartment T without separately opening and closing the tonneau cover device 10 alone.
In this embodiment, the slide mechanism 40 includes a wire member 42 in which the upper end portion 42b is fixed to the back door 4 and the intermediate portion 42a is fixed to the slider member 41 (see FIG. 5). .
Thereby, the opening / closing operation | movement of the tonneau cover apparatus 10 can be produced using the opening / closing operation | movement of backdoor 4 itself.
Therefore, the opening / closing operation of the back door 4 and the opening / closing operation of the tonneau cover device 10 can be mechanically linked with a simple structure such as the wire member 42, and the production cost can be reduced.

Next, a second embodiment will be described with reference to FIGS.
FIG. 17 is a side view of a cargo compartment equipped with the tonneau cover device according to the second embodiment, and FIG. 18 is a schematic diagram of the opening / closing operation of the tonneau cover device, in which (a) is in a closed state and (b) is in the middle of opening. The state, (c) is a schematic diagram showing an open state. In addition, about the component same as the above-mentioned embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  As shown in FIG. 17, the tonneau cover device 110 of this embodiment is configured such that, on the contrary to the first embodiment, the rear dividing board (124) of the front tonneau cover 120 is replaced with the front dividing board (121, 122, 123) and is set so as to cause valley deformation between the third board 123 and the fourth board 124.

  That is, as shown in FIG. 18A, the shelf 106 that supports the front tonneau cover 120 has an upper stage 161 as its front side, a lower stage 162 as its rear side, and an inclined part 163 that is rearwardly lowered at its middle position. Thus, when the front tonneau cover 120 is displaced upward, it is set so that valley deformation occurs between the third board 123 and the fourth board 124.

The opening / closing operation of the tonneau cover device 110 will be described with reference to FIG.
In the closed state of (a), since the slider member 41 is located at the lower end of the slide rail 8, both the front tonneau cover 120 and the rear tonneau cover 130 are deployed above the luggage compartment T in a substantially horizontal state.

  However, when the slider member 41 moves to the intermediate position of the slide rail 8 as shown in the middle state of opening of (b), the fourth board 124 is pressed forward from the rear, and the front end 124a of the fourth board 124 is moved to the second position. The movement to be submerged below the three boards 123 is generated. As a result, a valley break occurs between the third board 123 and the fourth board 124.

  That is, as shown in (a), since the bending angle γ formed between the third board 123 and the fourth board 124 is formed upward, this bending portion R becomes a “trigger” and valley folding deformation occurs. It happens.

  Furthermore, in this embodiment, since the position of the engaging boss portion 36 of the winding unit 31 is also set above the plane extension line S of the third board 123, the valley fold deformation is further promoted. .

  And in the open state of (c), the 2nd board 122 is also pressed from back, the rear end 122a is displaced so that it may move upwards, and it is displaced upwards together with the 3rd board 123 and the 4th board 124. . In this way, the opening TO at the rear of the luggage compartment is enlarged, and it becomes easy to take in and out the luggage from the rear of the vehicle body.

With this configuration, even in this embodiment, the third board 123 and the fourth board 124 of the front tonneau cover 120 can be bent by valley folding to enlarge the opening TO at the rear of the cargo compartment T. it can.
In particular, since the folded intermediate divided boards (the second board 122 and the third board 123) are not exposed to the lower side in the open state by being bent by the valley deformation, the divided boards 122 and 123 are There is no interference with the package when loading and unloading. Therefore, the loading / unloading of the luggage can be performed more smoothly, and the usability of the tonneau cover device 110 can be improved.
Other functions and effects are the same as those in the first embodiment.

Next, a third embodiment will be described with reference to FIGS. 19, 20, and 21.
FIG. 19 is a side view of a luggage compartment equipped with the tonneau cover device of the third embodiment, FIG. 20 is a side view of the cargo compartment when the tonneau cover device is moved upward with the back door closed, and FIG. FIG. 2 is a system block diagram for controlling the tonneau cover device. In addition, about the component same as the above-mentioned embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  The tonneau cover device 210 of this embodiment is configured to slide the slider member 41 using the electric actuator 200 without using the opening / closing operation of the back door 4.

  Specifically, as shown in FIG. 19, an upper pulley 201 and a lower pulley 202 are installed above and below the slide rail 8, and a belt member 203 is wound between the upper pulley 201 and the lower pulley 202. The slider member 41 is fixed to the belt member 203, and the belt member 203 is configured to be driven by an electric actuator 200 such as a stepping motor.

  The electric actuator 200 is controlled by the system block shown in FIG. The CPU 204 that controls the electric actuator 200 is connected with a vehicle speed sensor 205, a back door sensor 206, and a manual button 207 as input means. The vehicle speed sensor 205 is used to stop the vehicle, and the back door sensor 206 is used to open and close the back door 4. The state / manual button 207 is configured to capture an operator's opening / closing operation request.

  The CPU 204 performs arithmetic control based on the information thus acquired, and outputs an open / close signal or the like to the electric actuator 200 that is an output means.

Therefore, for example, as shown in FIG. 20, it is possible to obtain a state in which the tonneau cover device 210 is opened although the back door 4 is closed regardless of the opening / closing operation of the back door 4.
By obtaining such a state, it is possible to obtain an advantage that the luggage can be accommodated even when the luggage in the luggage compartment T cannot be accommodated in the luggage compartment T when the tonneau cover device is deployed. .

  Although not shown, since the opening / closing speed of the tonneau cover device 210 can be set independently of the opening / closing speed of the back door 4, the opening / closing operation of the tonneau cover apparatus 210 can always be the same speed.

Thus, in this embodiment, the slide mechanism 40 is configured including the electric actuator 200.
Accordingly, the tonneau cover device 210 can be freely opened and closed regardless of the opening and closing operation of the back door 4 itself. Further, since the opening / closing speed of the tonneau cover device 210 is not restricted by the opening / closing speed of the back door 4, the tonneau cover apparatus 210 can be freely opened and closed.
Therefore, the degree of freedom of the opening / closing operation of the tonneau cover device 210 can be increased, and the functionality of the tonneau cover device 210 can be further enhanced.
Other functions and effects are the same as those in the first embodiment.

Protruding portion 324a (see FIG. 23) that protrudes outward is provided, and a leg portion 325 that is a guide portion is provided on the lower surface of this protruding portion 324a, thereby bending downward between the fourth board 324 and the third board 323. An angle δ is formed.

  In this way, the bending angle δ is formed on the lower side between the third board 323 and the fourth board 324, so that the rear end of the front tonneau cover 320 is also used in this embodiment as in the first embodiment. When it is moved upward by the slide mechanism 40 or the like, it is possible to cause a mountain-shaped deformation between the third board 323 and the fourth board 324.

  Specifically, as shown in FIG. 23, a protruding portion 324a that protrudes outward is formed at the front side end of the fourth board 324, and the lower surface of the protruding portion 324a contacts the shelf 306. A cylindrical boss-like leg 325 is fixed so as to be in contact. Although not shown, a similar leg 325 is provided on the opposite side.
