DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, the sick, disabled, and bedridden elderly (hereinafter simply referred to as "the sick, etc.").
More particularly, the present invention relates to a bed device which can be easily used at home and can be used in a wide range of uses.

[0002]

2. Description of the Related Art Along with the development of medical equipment, a bed apparatus having various functions or a nursing care apparatus used in conjunction with a bed has been proposed.

The present applicant has proposed an improved bed apparatus in Japanese Patent Application Laid-Open No. Hei 2-215462.
This bed device, considering the housing situation in Japan,
For example, it can be used even in a room of about 6 tatami mats or 4.5 tatami mats, and has a function that can easily drop a sick person from the bed body or put it on the bed body. Have been. In addition, this bed device is also devised so as to be able to assist rehabilitation of a sick person or the like.

[0004] The bed apparatus described above specifically includes a pair of guides fixedly provided to the bed body so as to extend in the width direction of the bed body at both ends in the longitudinal direction of the bed body. A pair of sliders is attached so that each of these guides slides in the width direction of the bed body. These sliders project to the side of the bed body by sliding along the guide. In addition, a column is attached to each slider so as to extend upward from each slider. A support member is mounted movably along each column. The support member can be stopped at an arbitrary position moved along each of the columns. A pair of parallel side bars extending in the horizontal direction is connected between the support members. A hanger member for holding a sick person or the like is attached using these side bars.

In the above-described bed apparatus, the pair of columns is positioned at a position within the width direction of the bed body and at a position deviating from the width direction of the bed body in response to each slider sliding along each guide. It is movable between and.
Further, the support member can be moved up and down along each of the columns, and can be stopped at the moved position, regardless of the position of the columns. As a result, the pair of support members can take any positions within the space above the bed body and the space beside the bed body.

Therefore, by utilizing such a movement of the support member, a sick person or the like lying on the bed body can be moved to the side of the bed body, and can be moved in the opposite direction. Can be done. Therefore, according to this bed device, the sick or the like is lowered from the bed body,
Bathing, getting on a wheelchair, and conversely, returning to the bed body can be easily performed.

[0007]

However, the bed apparatus described above tends to require a relatively complicated and large-scale mechanism. For example, a mechanism for allowing the slider to slide along the guide, a configuration for allowing the support member to move along the column, and the like provide the above-described tendency.

As a result, the bed apparatus becomes expensive, and there is an obstacle in terms of cost in order to spread it to general households.

[0009] Further, the entire bed apparatus is heavy, and depending on the room in which the bed apparatus is installed, there is a case where floor reinforcement work is required.

Therefore, an object of the present invention is to substantially satisfy the functions of the conventional bed apparatus described above,
It is an object of the present invention to provide a bed apparatus which can be simplified and reduced in weight.

[0011]

A bed apparatus according to the present invention first has a longitudinal dimension and a width dimension.
A bed body is provided. A pair of struts extending relatively upward are attached to both ends in the longitudinal direction of the bed body. These pillars are rotatable in the width direction of the bed main body at their mounting portions. A horizontal bar is connected between the upper ends of the pair of columns, and a hanger member is attached to the horizontal bar.

[0012]

In the bed apparatus according to the present invention, the horizontal bar can be moved between a position above the bed body and a position on the side of the bed body in accordance with the rotation of the column.

[0013]

Thus, according to the present invention, the hanger member can be moved at least between the position above the bed and the position on the side by utilizing the movement of the horizontal bar described above. Since the hanger member holds a sick person or the like, the sick person or the like can be similarly moved between a position above the bed body and a side position.

Further, if a hoist-like hoisting mechanism is added to the hanger member itself, the sick person or the like can be moved up and down. Therefore, in combination with the operation of the horizontal bar described above, the sick person or the like held by the hanger member can be moved to any position within the space above the bed body and the space beside the bed body. it can. Therefore, it is possible to easily take the sick person or the like down from the bed body, take a bath, put on a wheelchair, and conversely, return the patient to the bed body.

If several types of hanger members are prepared to be attached to the horizontal bar, depending on the purpose or the symptoms of the sick, the sick or the like may be in a lying posture or a sitting posture. , Etc., can be moved in any posture. In addition, the horizontal bar or the hanger member can be used as a body support when a sick person or the like performs rehabilitation.

Further, the bed apparatus according to the present invention basically utilizes the rotation of the column. The mechanism for enabling such rotation can be simplified and reduced in weight as compared with the mechanism for enabling sliding in the conventional bed apparatus described above. Therefore, the bed apparatus according to the present invention can be manufactured relatively inexpensively, and the floor work of the room where the bed apparatus is installed is not particularly required. for that reason,
This bed apparatus is particularly suitable for use in ordinary households.

[0017]

1 and 2 show a bed apparatus 1 according to an embodiment of the present invention.

The bed apparatus 1 includes a bed body 3 on which a mattress 2 is laid. A pair of columns 4 and 5 are disposed at both ends in the longitudinal direction of the bed body 3 in a state of extending relatively upward. A horizontal bar 6 is connected between the upper ends of the columns 4 and 5. In this example,
The columns 4 and 5 and the horizontal bar 6 are constituted by a series of tubing. A hanger member 7 is attached to the horizontal bar 6.

More specifically, the bed body 3 is provided with end boards 8 and 9 that form legs at both ends in the longitudinal direction. Each of the columns 4 and 5 is attached rotatably in the width direction of the bed body 3 by shafts 10 and 11 located on end boards 8 and 9, respectively. Preferably, the shafts 10 and 11 are offset on one side of each of the end boards 8 and 9.

Rotation driving mechanisms 12 and 13 for driving the rotation of the pair of columns 4 and 5 are formed on end boards 8 and 9, respectively. One rotation drive mechanism 1
2 are shown in FIG. With reference to FIG. 1, the rotation drive mechanism 12 includes a motor 14 that can rotate forward and reverse, and the rotation of the motor 14 is transmitted to a female screw member 17 via a speed reducer 15 and a gear 16. The female screw member 17 includes a gear 16
Is formed on the outer periphery thereof, and a female screw is formed on the inner periphery thereof. The lead screw 18 having a male screw to be screwed into the female screw is provided on the bracket 1.
9, 20, 21 and 22 are provided so as to be able to translate in the direction of arrow 23. An engagement yoke 24 is provided at an end of the lead screw 18, and the engagement yoke 24 is provided with an engagement hole 25 that is long in the vertical direction. On the other hand, an engaging pin 26 that is received in the engaging hole 25 is attached to the column 4.

In the above-described rotary drive mechanism 12, when the motor 14 rotates, the female screw member 17 also rotates. Since the movement of the female screw member 17 in the axial direction is prohibited by the brackets 20 and 21, the female screw member 1
The rotation of 7 causes the lead screw 18 to translate in the direction of the arrow 23. This operation is transmitted to the column 4 via the engagement yoke 24 and the engagement pin 26, and the column 4 rotates as shown by the arrow 27. The reason why the engaging hole 25 is formed in a vertically long shape is that the position of the engaging pin 26 slightly changes in the vertical direction due to the rotation of the support column 4.

Although not shown in detail, the structure employed in the above-described rotation drive mechanism 12 is also applied to the other rotation drive mechanism 13.

A hanger member 7 attached to the horizontal bar 6
Has a winding mechanism 28. The housing 29 of the hoisting mechanism 28 is attached to the horizontal bar 6 so as to be rotatable around its axis. The hoisting mechanism 28 is rotatable forward and reverse and includes a motor 30 to which a speed reducer is added. A plurality of winding drums 32 are fixed on a rotating shaft 31 derived from the motor 30. A rope 33 is wound around each winding drum 32, and a rectangular frame 3 is provided at a lower end of the rope 33.
4 are connected. The size of the frame 34 is selected so as to surround the sick person or the like who is laid on the bed body 3. The frame 34 can be displaced in the vertical direction as indicated by an arrow 35 in FIG.

A plurality of hanger shovels 36 are mounted on the frame 34. Hanger shovel 36
Is composed of a relatively rigid material such as, for example, hard plastic, aluminum, stainless steel. As shown in FIG. 1, the hanger shovel 36 has a shape which is curved so as to form an L-shape as a whole, and its horizontal portion 37 contacts the lower surface of the body of a sick person or the like. Also, at the upper end of the hanger shovel 36,
A hook portion 38 that can be engaged with the frame 34 is formed.

In using the hanger shovel 36, first, the horizontal portion 37 is inserted under the body of a sick person or the like lying on the bed body 3. At this time, the plurality of hanger shovels 36 are appropriately distributed on both sides of the body of the sick person or the like in consideration of the weight of the sick person or the like. On the other hand, in consideration of the position of the hook portion 38 of the hanger shovel 36, the height of the frame 34 is
8 adjusted. And each hanger shovel 3
The sixth hook portion 38 is engaged with the frame 34.

According to the hanger shovel 36 described above,
This is advantageous in that it can be inserted under the body of the sick person or the like without lifting the sick person or the like.

Next, a method of using the bed apparatus 1 will be described. First, when the columns 4 and 5 are in the state shown by the solid line in FIG. 1, the sick person or the like lying on the bed body 3 is lifted. Multiple hanger shovels 36
After the horizontal portion 37 is inserted under the body of a sick person or the like, the hook portion 38 is engaged with the frame 34.

Next, the winding mechanism 28 is driven to lift the frame 34 upward. As a result, the hanger shovel 36 supporting the sick person or the like is also displaced upward and brought to a height away from the mattress 2 on the bed body 3.

When replacing sheets or the like laid on the mattress 2, this can be easily performed in this state. If only this operation is necessary, it may be restored to the original state when this operation is completed. When moving the sick person or the like to a position shifted to the side of the bed body 3 as in the case of bathing the sick person or the like, the following operation is further performed.

The rotation driving mechanisms 12 and 13 are simultaneously driven, and the columns 4 and 5 are rotated to an angle shown by imaginary lines in FIG. Thereby, the hanger member 7
Is moved to a position shifted laterally from the upper part of the bed body 3 while keeping the same height from above the bed body 3 with the sick person or the like.

Next, for example, a bathtub is placed immediately below the sick person or the like in the above-described position. Next, the winding mechanism 28 is driven, and the frame 34 is moved downward with a sick person or the like. At the end of this movement, the sick or the like can be put in the bathtub and bathed.

To return the sick person or the like to the bed body 3 again, an operation reverse to the above operation may be performed.

While the invention has been described with reference to the illustrated embodiment, several other modifications are possible within the scope of the invention.

[0034]

Further, the hanger member may be replaced with a structure including, for example, a hammock that can carry a sick person or the like in a sitting posture.

The rotation of the columns 4 and 5 and the vertical displacement of the frame 34 may be achieved, for example, manually.
