Description

Curtain rail structure {CURTAIN RAIL STRUCTURE}

The present invention relates to a structure of a curtain rail suitable for hanging a curtain for partitioning a bed room, such as a bed room, a bed or a large room of an inn, in a cooperative hospital room of a hospital.

Conventionally, a curtain rail structure has been disclosed in which the leading end side of one main rail on the base end side branches to a plurality of bails through a branch portion, and a plurality of curtain runners can freely run in each of the rails (for example, , See Patent Document 1). In this curtain rail structure, a connecting plate for connecting the main rail and the bail is formed at the branching portion. A swinging rail is pivotally supported on the connecting plate so as to freely swing with respect to the connecting plate, and a swinging rail is formed on the swinging part, the swinging rail being connectable with the main rail and each of the bradles according to the swinging position. In addition, a self-supporting retention mechanism for regulating the swinging angle of the swinging rail and for maintaining the swinging rail at a desired position is formed in the branching portion. This self-sustaining holding mechanism is a mechanism in which a magnet and a magnetic body are used and held by a magnetic force. Specifically, the holding mechanism is constituted by a stopper member mounted on both side surfaces of the connecting plate, a magnetic body fixed to the inner surface side of the stopper member, and a magnet mounted on both side surfaces of the swinging rail.

In the curtain rail structure thus constructed, when changing the direction in which the curtain is to be changed, for example, in a state in which the curtain runner at the head is once returned to the front of the branch portion and several curtain runners at the head side are fixed to the swing rail, The swing rails can be swung to the desired bail side to switch the railway. For this reason, when a space near the bottom of the bed is placed in the vicinity of the bottom of the bed at the time of rounding or the like using a bale near the bottom of the bed at normal time, once the leading curtain runner is returned to the front of the bifurcation, So that it is possible to secure a large space between the bottom end of the bed and the curtain so that interference between the cart and the curtain can be prevented.

On the other hand, in the curtain rail structure of Patent Document 1, as long as the leading curtain runner does not pass the branch portion toward the retreating direction after the leading curtain runner has passed the branch portion toward the advancing direction, A lock mechanism for fixing the position is formed. In this lock mechanism, a long groove notch is formed at the center of the front end side of the intermediate wall partitioning the upper hollow portion and the lower hollow portion of the swing rail, and a lock member having a rectangular shape on the intermediate wall and a protrusion on the lower- do. And the protrusion of the lower surface is passed through the notch on the long groove to protrude from the lower hollow portion so that the lock member can freely slide along the notch. Further, the projecting portion is formed only at the top of the leading curtain runner.

As a result, when the leading curtain runner passes under the lock member, the projecting portion of the leading curtain runner advances or retracts and collides with the projection of the lock member, the projection pushes the projection to slide the lock member along the notch. When the protrusion reaches the end of the notch and the place to go is lost, the lock member slightly rises and the protrusion of the leading curtain runner passes through the protrusion of the lock member. Thereafter, the lock member is lowered by its own weight, And the swing rails are fixed to the baille on the branch side.

However, in the curtain rail structure disclosed in the above-mentioned conventional patent document 1, the attraction force of the magnet and the magnetic body is used as a holding mechanism for holding the swing rail at a desired position, and when the swing rails are switched, The curled magnet is separated from the magnetic body by pulling the curtain away from the magnetic body. Therefore, a relatively large operating force is required and the operability may be deteriorated. Further, in the curtain rail structure disclosed in the above-mentioned conventional patent document 1, when the magnetic force of the magnets is deviated for each curtain rail by the individual difference of the magnets, there is also a problem that the operating force for switching the swing rails varies from one curtain rail to another . In the curtain rail structure disclosed in the above-mentioned conventional patent document 1, when the leading curtain runner passes under the lock member, the projecting portion of the leading curtain runner presses the projection of the lock member to slide the lock member along the notch After the lock member enters the bail on the branch side to fix the swing rail to the bail, the lock member slightly rises and the protrusion of the leading curtain runner passes through the protrusion of the lock member. For example, The lock member slightly rises before the lock member enters the bail on the branch side so that the projecting portion of the leading curtain runner passes through the projection of the lock member so that the branch of the swing rail There is a possibility that fixation to the bail on the branch side of the swing rail becomes incomplete or incomplete release of the fixation on the bail on the branch side of the swing rail may be incomplete.

The second magnet 52 is connected to the first magnet 51 at a predetermined distance in the width direction of the connecting plate 21 when the swing rail 22 is connected to the first bobbin 11, And is shifted to one side surface side of the plate 21 (Fig. 4 (a)). 4 (a), when the swing rails 22 are connected to the first bobbin 11 in a communicative manner, the second magnets 52 are repelled in the direction of the solid line arrows in FIG. 4 The second magnet 52 is repelled against the magnetic force of the first magnet 51 in the direction in which the sliding pin 32 is pushed to one end of the elongated hole 21f (the direction of the solid line arrow in FIG. . The second magnet 52 is connected to the first magnet 51 by a predetermined distance in the width direction of the connecting plate 21 when the swing rail 22 is connected to the second bobbin 12, And is shifted to the other side of the plate 21 (Fig. 4 (b)). This causes the second magnet 52 to be repelled in the direction of the broken arrow in Figure 4 (b) with respect to the magnetic force of the first magnet 51 when the swing rail 22 is connected to the second bore 12, The second magnet 52 is repelled against the magnetic force of the first magnet 51 in the direction of pushing the sliding pin 32 to the other end of the slot 21f (the direction of the broken arrow in FIG. 3 (b) . Further, the first and second magnets 51 and 52 are arranged such that the same magnetic poles face each other. As a result, the first and second magnetic poles 51 and 52 are repelled by their magnetic forces.

A locking mechanism 54 is provided between the connecting plate 21 and the swinging rail 22 to fix the swinging rail 22 at a predetermined swing angle with respect to the connecting plate 21 or to release the swinging rail 22 (Figs. 2 and 5). 5B) for fixing the swing rail 22 to the connecting plate 21 and a releasing position for releasing the fixing to the connecting plate 21 of the swing rail 22 (Fig. 5A). The center of the swing connection piece 22b is removed and the remaining part of the swing connection piece 22b is raised to the upper end of the pair of swing side pieces 22a and 22a so that the pair of swing rising pieces 22 22j, and 22j are formed (Figs. 2, 5, and 9). In addition, on the lower end of the distal end of the connecting plate 21, a standing-piece accommodating recess 21j is formed (Fig. 1, Fig. 2, and Fig. 5) capable of accommodating the pair of swing-and-guttering members 22j and 22j. The standing piece receiving recess 21j is formed relatively large so that a pair of the oscillating standing pieces 22j and 22j do not interfere with the connecting plate 21 even if the swing rail 22 swings. The first and second stopper accommodating recesses 21k and 21m are formed on the upper surface of the standing piece receiving recess 21j at a predetermined interval in the width direction of the connecting plate 21, respectively. The first stopper accommodating concave portion 21k is formed on one side surface side of the connecting plate 21 and the second stopper accommodating concave portion 21m is formed on the other side surface side of the connecting plate 21.

The transition stopper 56 is mounted such that the proximal end thereof is rotatable through the stopper supporting shaft 57 to the pair of the oscillating standing pieces 22j and 22j (Figs. 2, 5 and 6) . The stopper rotation restricting shaft 58 is inserted into the base end of the switching stopper 56 so that the pair of swinging upright pieces 22j and 22j extend from the pair of swing side pieces 22a and 22a to the substantially semi- A pair of rotational movement restricting recesses 22k and 22k are formed respectively (Figs. 5, 7 and 9). Both ends of the stopper rotation restricting shaft 58 protruded from both ends of the switching stopper 56 are respectively inserted into the pair of rotation restricting recesses 22k and 22k. The stopper temporary fastener 59 is attached to the center front end of the switching stopper 56 (Figs. 2, 5, and 8). The stopper temporary fastener 59 is composed of a fixed shaft 59a inserted at the center front end of the switching stopper 56 and a pair of right and left stoppers 59a and 59d inserted into a pair of holes 59d and 59d at both ends of the fixed shaft 59a, And a pair of steel balls 59c and 59c elastically supported to be projected outward by the springs 59b and 59b (FIG. 8). A pair of first fixing holes 22m and 22m are formed so as to face each other on the pair of swing side pieces 22a and 22a of the swing rail 22 and a pair of swing standing pieces 22j and 22j, A pair of second fixing holes 22n and 22n are formed respectively above the pair of first fixing holes 22m and 22m so as to face each other (Figs. 5 and 8). When the pair of steel balls 59c and 59c are partially inserted into the pair of first fixing holes 22m and 22m, the distal end portion of the switching stopper 56 is engaged with the first and second stopper accommodating recesses 21k and 21m When the switching stopper 56 is temporarily fixed at a position where it is not accommodated in the first fixing holes 22n and 22n and a part of the pair of steel balls 59c and 59c is inserted into the pair of second fixing holes 22n and 22n , And the switching stopper 56 is temporarily fixed to the position where the distal end portion of the switching stopper 56 is accommodated in any one of the first or second stopper accommodating recesses 21k and 21m, that is, the fixed position.

On the other hand, the rolling member 14a of the leading curtain runner 14 among the plurality of curtain runners 14 and 16 is formed to have a larger diameter than the rolling members 16a of the other curtain runners 16 (see Figs. 2 and 5 ). The leading curtain runner 14 is a curtain runner 14 that passes from the main rail 13 to the swing rails 22 and has a plurality of curtain runners 14 facing either one of the first and second baffles 11, Refers to the leading curtain runner 14 among the curtain runners 14 and 16. The lower surface of the switching stopper 56 is larger than the radius of the rolling member 14a so as to rotate around the stopper supporting shaft 57 by the passage of the rolling member 14a of the leading curtain runner 14. [ And is formed as a curved surface having a radius of curvature. The rolling member 14a of the leading curtain runner 14 comes into contact with the lower surface of the switching stopper 56 when the leading curtain runner 14 advances and passes through the lock mechanism 54, The rolling member 14a of the leading curtain runner 14 abuts against the lower surface of the switching stopper 56 when the leading curtain runner 14 is retracted and passes through the lock mechanism 54 And to switch the switching stopper 56 to the release position. However, even if the other curtain runner 16 advances or retreats and passes through the lock mechanism 54, the rolling member 16a of the other curtain runner 16 is configured not to switch the switching stopper 56. [ Reference numeral 14b in Fig. 5 denotes a hook formed in the leading curtain runner 14 and hooked to suspend the curtain 18. The reference numeral 16b in Fig. 5 is formed in another curtain runner 16, 18). ≪ / RTI > Reference numeral 61 in Fig. 10 is a hanging rod for receiving the main rail 13 and the bails 11, 12 from the ceiling of the room.

The assembling procedure of the curtain rail structure thus constructed will be described. A plurality of suspension rods 61 are received from the ceiling of the room and the main rails 13 and the first and second bures 11 and 12 are mounted on the lower ends of the suspension rods 61 10). The plurality of curtain runners 14 and 16 are engaged with the main rails 13 so that the rolling members 14a and 16a can transfer the pair of lower pieces 13c and 13c. On the other hand, the lock mechanism 54 is mounted on the swing rail 22 and the second magnet 52 is inserted. The first and second adjusting screws 41 and 42 are screwed to the first and second screw holes 21g and 21h of the connecting plate 21 and then screwed into the first and second adjusting screws 41 and 42 The lock nuts 43 and 44 are screwed to each other. The second magnet 52 is attracted to the lower surface of the magnet adjustment screw 53 by the magnetic force after screwing the magnet adjustment screw 53 to the magnet screw hole 21i of the connection plate 21. At this time, the magnetic pole on the lower surface side of the second magnet 52 is made the same as the magnetic pole on the upper surface side of the first magnet 51. Next, the swing rails 22 are pivotally mountable on the lower surface of the connecting plate 21 via the swinging shafts 28 and the sliding pins 32. In this state, after the main insertion portion 21a of the connection plate 21 is inserted into the connection hole 13e of the main rail 13, the first insertion portion 21c of the connection plate 21 is inserted into the first bore Is inserted into the first connecting hole 11e of the work 11 and the second portion inserting portion 21d of the connecting plate 21 is inserted into the second connecting hole 12e of the second bore 12 do. The main inserting portion 21a is fixed in the state of being inserted into the connecting hole 13e by screwing the screw 24 into the screw hole of the main inserting portion 21a, The first portion inserting portion 21c is inserted into the first connecting hole 11e and is screwed into the screw hole of the second inserting portion 21c so that the screw 27 is inserted into the second inserting portion 21d, The second insertion portion 21d is inserted and fixed in the second connection hole 12e. The swing rails 22 are pivoted to adjust the first and second adjusting screws 41 and 42 so that the swing rails 22 are aligned with the first or second bushes 11 and 12 so that the lock nuts 43 And 44 and adjusts the magnetic force of the first magnet 51 with respect to the second magnet 52 by means of the adjustment screw 53 for the magnet. As a result, when the curtain runners 14 and 16 pass between the swing rails 22 and the bushes 11 and 12, it is possible to generate almost no sound, The magnetic forces acting between the first and second magnets 51 and 52 can be easily adjusted by the optimum magnetic force even when the magnetic forces of the first and second magnets 51 and 52 are varied. The above operation completes the assembly of the curtain rail structure. Thereafter, hooks of the curtains 18 are engaged with the circular rings 14b, 16b of the plurality of curtain runners 14, 16 to thereby fasten the curtains 18.

The operation of the curtain rail structure thus assembled will be described. When the cart is not placed under the leg of the bed 17 of the sickroom, the curtain 18 is developed in a state of approaching under the leg of the bed 17. That is, one end of the curtain 18, which is arranged below the main rail 13, is pulled toward the swing rail 22 while pulling in the direction approaching the bed 17. Since the head curtain runner 14 also has a force in a direction approaching the side surface of the bed 17, when the leading curtain runner 14 moves from the main rail 13 to the swing rail 22, The front end of the rail 22 rotates about the pivot shaft 28 in a direction in which the front end of the rail 22 communicates with the first bobbin 11. At this time, the second magnet 52 is moved in the direction in which the sliding pin 32 is pressed to one end of the long hole 21f, that is, the direction in which the collar 33 is pressed against the tip of the first adjusting screw 41, The tip end of the swing rail 22 is held in a state of being connected to the first bobbin 11 in a communicative manner.

When the leading curtain runner 14 advances and passes the lock mechanism 54, the rolling body 14a of the leading curtain runner 14 abuts against the curved lower surface of the switching stopper 56, 56) to a fixed position. That is, the distal end portion of the switching stopper 56 is inserted into the first stopper accommodating concave portion 21k of the connecting plate 21. A part of the steel ball 59c of the stopper temporary fastener 59 is inserted into the second fixing hole 22n so that the tip of the switching stopper 56 is temporarily inserted into the first stopper accommodating concave portion 21k . As a result, the communication connection with the first bobbin 11 of the swing rail 22 is not unintentionally released. Even if the other curtain runner 16 advances and passes the lock mechanism 54, the rolling member 16a of the other curtain runner 16 is smaller than the rolling member 14a of the leading curtain runner 14 And therefore does not abut the lower surface of the switching stopper 56. [ As a result, the rolling member 16a of the other curtain runner 16 does not inadvertently switch the switching stopper 56. [ When the leading curtain runner 14 moves to the front end of the first bobbin 11, the curtain 18 is deployed under the main rail 13, the swing rail 22 and the first bobbin 11, do. At this time, since the curtain 18 is developed in a state in which it approaches the bottom of the bed 17, the passage between the bed 17 and the bed facing the bed 17 can be widely secured.

When the opened curtain 18 is arranged below the main rail 13, one end of the expanded curtain 18 is moved in the direction opposite to the above. When the leading curtain runner 14 retreats and passes the lock mechanism 54, the rolling body 14a of the leading curtain runner 14 abuts against the curved lower surface of the switching stopper 54, To the release position. That is, the distal end portion of the switching stopper 56 inserted into the first stopper accommodating concave portion 21k of the connecting plate 21 is disengaged from the first stopper accommodating concave portion 21k. At this time, a part of the steel ball 59c of the stopper temporary fastener 59 is inserted into the first fixing hole 22m, so that the tip end of the switching stopper 56 is temporarily disengaged from the first stopper accommodating concave portion 21k . Since the rolling members 16a of the other curtain runners 16 are smaller than the rolling members 14a of the leading curtain runners 14 even if the other curtain runners 16 are retracted and pass the lock mechanism 54 , And does not abut the lower surface of the switching stopper 56. [ As a result, the rolling member 16a of the other curtain runner 16 does not inadvertently switch the switching stopper 56. [ When the leading curtain runner 14 is retracted from the first bore 11 to the main rail 13 through the swing rail 22, the curtain 18 is arranged below the main rail 13.

On the other hand, when the cart is placed under the legs of the bed 17 of the sickroom for rounding or the like, the curtains 18 are developed in a state of being dropped from under the legs of the bed 17. That is, one end of the curtain 18, which is arranged below the main rail 13, is pulled toward the swing rail 22 while being pulled in a direction to separate it from the bed 17. When the leading curtain runner 14 moves from the main rail 13 to the swing rail 22 because the leading curtain runner 14 is also provided with a force in the direction away from the side surface of the bed 17, (22) is rotated around the pivot shaft (28) in the direction in which the tip of the pivot shaft (22) communicates with the second bollard (12). At this time, the force pressing the sliding pin 32 to one end of the slot 21f, that is, the force pressing the collar 33 against the tip of the first adjusting screw 41 is determined by the force of the second magnet 52 ), It is relatively weak. As a result, the operation force at the time of switching the swing rails 22 can be reduced, the swing rails 22 rapidly rotate about the swing shaft 28, and the collar 33 is rotated about the second adjustment screw 42, . When the collar 33 comes into contact with the front end of the second adjusting screw 42, the direction in which the sliding pin 32 is pressed to the other end of the long hole 21f, The tip end of the swing rail 22 is maintained in a state of being connected to the second bobbin 12 in a communicative manner because the second magnet 52 is repulsive to the magnetic force of the first magnet 51 in the direction in which the second magnet 52 is pressed.

When the leading curtain runner 14 advances and passes the lock mechanism 54, the rolling body 14a of the leading curtain runner 14 abuts against the curved lower surface of the switching stopper 56, 56) to a fixed position. That is, the distal end portion of the switching stopper 56 is inserted into the second stopper accommodating concave portion 21m of the connecting plate 21. At this time, a part of the steel ball 59c of the stopper temporary fastener 59 is inserted into the second fixing hole 22n, so that the tip end of the switching stopper 56 is temporarily inserted into the second stopper accommodating concave portion 21m . As a result, the communication connection of the swing rail 22 with the second bore 12 is not unintentionally released. Even if the other curtain runner 16 advances and passes through the lock mechanism 54, since the rolling member 16a of the other curtain runner 16 is smaller than the rolling member 14a of the leading curtain runner 14 , And does not abut the lower surface of the switching stopper 56. [ As a result, the rolling member 16a of the other curtain runner 16 does not inadvertently switch the switching stopper 56. [ When the leading curtain runner 14 moves to the front end of the second bobbin 12, the curtain 18 is unfolded below the main rail 13, the swing rail 22 and the second bobbin 12, do. At this time, since the curtain 18 is deployed away from the bottom of the bed 17, a space for placing the cart under the leg of the bed 17 can be ensured. In this manner, the width of the space between the leg bottom of the bed 17 and the curtain 18 can be adjusted as needed.

When the opened curtain 18 is arranged below the main rail 13, one end of the expanded curtain 18 is moved in the direction opposite to the above. When the leading curtain runner 14 retracts and passes the lock mechanism 54, the rolling body 14a of the leading curtain runner 14 comes into contact with the curved lower surface of the switching stopper 56, To the release position. That is, the distal end portion of the switching stopper 56 inserted into the second stopper accommodating concave portion 21m of the connecting plate 21 is disengaged from the second stopper accommodating concave portion 21m. At this time, a part of the steel ball 59c of the stopper temporary fastener 59 is inserted into the first fixing hole 22m, so that the tip end of the switching stopper 56 is temporarily disengaged from the second stopper accommodating concave portion 21m . Since the rolling members 16a of the other curtain runners 16 are smaller than the rolling members 14a of the leading curtain runners 14 even if the other curtain runners 16 are retracted and pass the lock mechanism 54 , And does not abut the lower surface of the switching stopper 56. [ As a result, the rolling member 16a of the other curtain runner 16 does not inadvertently switch the switching stopper 56. [ When the leading curtain runner 14 is retracted from the second bore 12 to the main rail 13 through the swing rail 22, the curtain 18 is arranged below the main rail 13. [
