Abstract

PROBLEM TO BE SOLVED: To provide a runner having a gap elimination function for eliminating a gap between adjacent panel pairs, with an opening closed via the full extension of a free folding door. SOLUTION: A groove 14 is formed on the body 12 of a runner 6, and guides and supports a block 15 so as to be capable of sliding and reciprocating. A revolving shaft 11 for hanging a door panel 3 is connected to the block 15 so as to relatively rotatable. In addition, a compression spring 22 is provided between the block 15 and the body 12. In this case, the revolving shaft 11 integrated with the door panel 3 is made relatively slidable for the body 12 of the runner 6. Thus, when a stopper 36 at a rail end receives the body 12 prior to the full expansion of the panel pairs, the panel pairs are pushed back to the center of an opening, thereby eliminating a gap.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a runner for a hanging wheel type folding door. In particular, the runner has a gap removing function of pushing the door panel when fully closed back to the center side of the opening surface so that the panel-side ends adjacent to the left and right are in close contact with each other.

[0002]

2. Description of the Related Art A panel pair that can be bent in a V-shape is formed as a unit, and a plurality of panel pairs are individually bent and opened, or a free panel that can be moved left and right along a rail with any panel pair bent. There is a folding door. In this type of folding door, the width of the opening is set to be larger than the total width of all the panel pairs because the individual door panels need to be swung and pivoted about the runner axis suspended from the runner. . Therefore, in the closed state where all panel pairs are expanded,
There may be a gap between the side edges of the adjacent panel pair at the center of the opening. Conventionally, a clearance remover for removing the clearance is provided at a vertical frame of the opening or at a side end of the guide rail. Japanese Patent Application No. 8-28659 discloses an example of this kind of clearance removing device.

[0003]

As described above, the clearance remover made into a dedicated component as described above is relatively inexpensive, but requires extra cost and requires assembling time.

As described above, a free folding door can bend and open a plurality of panel pairs individually, and the open position can be freely selected. However, in many cases, in order to reduce the time required for opening and closing, the door panel located at the opening side end is temporarily fixed with a runner stopper so that the door panel located at the center of the opening can be bent open. Such a runner stopper is disclosed, for example, in Japanese Utility Model Publication No. 8-7008. Of course, when necessary, the door panel at the opening end can be separated from the runner stopper to be bent open. As described above, in the free folding door in which the door panel at the opening side is temporarily fixed by the runner stopper, the door panel at the side end is temporarily fixed by the runner stopper so as not to be movable. Even if a clearance removing tool is provided at the side end of the guide rail, the clearance removing action is not exerted, and a clearance is generated between the adjacent door panels at the center of the opening.

[0005] Most of the runners for folding doors are constructed as four wheels, but there are also runners of two wheels type in order to simplify the runner structure (Japanese Utility Model Publication No. 7-4308). This type of runner has a low cost but tends to meander when the door panel is opened and closed. In particular, when the panel pair moves left and right while being bent in a V-shape, a moment biased to the runner acts, so that the door panel is easily rattled and the runner may be caught on the guide rail.

SUMMARY OF THE INVENTION It is an object of the present invention to add a clearance removing function to the runner itself, to allow the panel pair at the fully closed state to be tightly joined without using a dedicated clearance removing device, and to reduce the cost by eliminating the clearance removing device. The aim is to provide runners for folding doors that can be reduced. An object of the present invention is to allow the panel pair to be moved to the center of the opening even when the door panel at the opening side end is temporarily fixed with a runner stopper, so that the panel pair at the time of full closing can be tightly joined. It is to make. SUMMARY OF THE INVENTION It is an object of the present invention to enable a pair of panels bent in a V-shape to be easily moved left and right without play.

[0012]

The pivot shaft 11 is located at one end of the groove 14 when the panel pair is bent and the opening surface is opened. When the panel pair is extended and the opening surface is closed, the body 12 of the runner 6 located at the side end of the opening surface comes into contact with, for example, a stopper 36 attached to the guide rail 1 to regulate the position. The stoppers 36 are provided at both ends of the guide rail 1, and the distance between the stoppers is set smaller than the distance between the outer ends of the body 12 of the runner 6 located at both ends of the folding door when all the panel pairs are extended. is there. Therefore, the body 12 of the runner 6 that has come into contact with the stopper 36 is pushed back relative to the door panel 3 by the difference between the aforementioned spacing dimensions. This pressing force is transmitted to the door panel 3 via the turning shaft 11. As a result, adjacent panel pairs are urged to move in opposite directions, and come into close contact at the center of the opening.

The form in which the runner 6 is temporarily fixed by the runner stopper 33 includes a case where the turning shaft 11 is engaged and captured and a case where the body 12 is engaged and captured. When the runner stopper 33 targets the turning shaft 11, the door panel is provided in the same manner as described above by providing the runner stopper 33 with an allowance in the catching groove or hole by a movement stroke capable of removing the gap. 3 can be moved to the center of the opening without any trouble.

The turning shaft 11 and the body 12 are connected to a block 15
When the block 15 is slid and guided by a groove 14 provided in the body 12, the pivot shaft 11 is prevented from tilting relative to the groove 14, and a runner for bending or expanding the panel pair is provided. Running becomes smooth. Since one end of the spring 22 is received by the block 15, it is possible to prevent the spring 22 from shifting and moving due to the rotation of the pivot shaft 11. According to the two-wheeled runner in which the roller shaft 20 is provided on the front and rear surfaces of the block 15 using the block 15 and the two rollers 13 are supported by the block 15 via the roller shaft 20, when a dedicated roller shaft is separately provided, In comparison, the number of runner components can be reduced.

A pair of runners 6 provided at the side ends of the panel pair
In a state in which the panel pair is bent in a V-shape, the restraint plates 16 provided on the body 12 come into contact with each other to regulate the close distance between the pair of door panels 3.3. Further, the contacting restraint plates 16, 16 are engaged with each other by the engaging teeth 17, 17, thereby restricting the movement of the runners 6, 6. The pair of runners 6 in this state move together as if they were four-wheeled runners having a large inter-wheel distance. Therefore, even in a V-shaped refraction state in which a large tilting moment acts on the runners 6, the straightness can be maintained and the panel pair can be moved right and left lightly.

In the runner described above, the body 12 and the turning shaft 11 slide relative to each other, so that
A spring force is generated between the three pairs, and the spring force removes an adjacent gap between the panel pairs. In the case of a runner in which the contact body 42 is provided on the body 12 of the traveling unit 9, the body 12 and the turning shaft 11 cannot slide relative to each other.

In each panel pair, the adjacent edges of the two door panels 3 are connected to each other by a hinge 4, and a handle 5 is provided near the bending edge of one door panel 3. The hinge 4 has a click mechanism that can maintain a fully open state. As shown in FIG. 3, a runner 6 and a steady rest roller 7, which are guided by the guide rails 1 and 2, respectively, are mounted on the upper and lower surfaces on both sides of each panel pair.

In FIG. 4, the runner 6 has a traveling portion 9 guided by the guide rail 1, a mounting portion 10 mounted in a state embedded in the door panel 3, and a swivel connecting the traveling portion 9 and the mounting portion 10. It is composed of the shaft 11 and the like.

The traveling portion 9 includes a rectangular block-shaped body 12 made of a plastic molded product, two rollers 13 disposed on the front and rear surfaces of the body 12, and a groove 14 provided in the body 12.
And a block 15 which reciprocates along. On one side end of the upper surface of the body 12, a restraining plate 16 wider than the body 12 is integrally protruded, and threaded engagement teeth 17 are formed on the protruding end surface. The groove 14 is formed by a vertical groove 14a penetrating the body 12 up and down, and a horizontal groove 14b crossing the vertical groove 14a and penetrating the body 12 in the front-rear direction. Slidably guided by Reference numeral 19 denotes a spring receiving hole.

The block 15 is formed by turning a metal square shaft, and has a roller shaft 20 integrally formed on the front and rear end surfaces of a central square block portion.
A vertical hole 21 for connecting the two is provided in a vertically penetrating manner. After assembling the compression coil type spring 22 in the spring receiving hole 19, the block 15 is inserted into the lateral groove 14 b and one end of the spring 22 is received by the block 15. In this assembled state, the roller 13 is assembled on a roller shaft 20 protruding from the front and rear surfaces of the body 12, and is freely rotatably supported. Roller shaft 20
Is caulked.

The mounting portion 10 includes a cylindrical case 24 having a flange 23 projecting from the upper end, and a case 24.
A nut 25 made of plastic is internally fitted in the plug 25, and a plug 26 is fitted in the lower end of the insertion hole for the nut 25. The insertion hole into which the nut 25 is inserted is formed in a hexagonal cross section, and holds the nut 25 and the plug 26 so that they cannot rotate relative to each other. The plug 26 is inseparably fixed with a pin penetrating the case 24. A set hole 27 is formed in a penetrating shape near the lower ends of the case 24 and the plug 26, respectively. After the case 24 is inserted into the mounting hole of the door panel 3 as shown in FIG. Set bolt 28 from the side end face side
By screwing the case 24, the case 24 can be prevented from coming off and fixed, and at the same time can be prevented from rotating.

The revolving shaft 11 is a turned product made of a hexagonal metal rod and has a hexagonal cross section operating portion 29 at the upper and lower central portions, and a round shaft portion above and below the operating portion 29. The screw part 30 which engages with the nut 25 is formed on the shaft part below the operation part 29. After the roller 31 is inserted into the upper round shaft portion, the round shaft portion is inserted into the vertical groove 14a from the lower surface side of the body 12, the upper portion thereof is inserted into the vertical hole 21 of the block 15, and the shaft end is inserted through the washer. The upper end of the turning shaft 11 is integrated with the block 15 by swaging. In this connected state, the turning shaft 11 is

The height of the door panel 3 can be adjusted.

The runner 6 is mounted such that the restraint plates 16 face each other to the door panels 3 constituting the panel pair. As a result, in a state where the panel pair is bent in a V-shape, the restraint plates 16 come into contact with each other as shown in FIG. The dentures 17 engage with each other unevenly,
The movement of the runner 6 on the contact partner side is restricted. As described above, when the adjacent runners 6 are constrained to each other via the restraint plates 16, the pair of runners 6 move together as if they were four-wheeled runners.
・ 6 can be prevented from meandering. Therefore, runner 6.6
Even when a large tilting moment acts on the panel pair, the panel pair moves straight forward lightly.

Runner stoppers 33 for temporarily fixing the runners 6 are provided on both side ends of the upper guide rail 1.
Is provided. 1 and 5, the runner stopper 33 is composed of a catcher 35 having a pair of fork-shaped elastic arms 34 and a nut body 37 having an L-shaped cross section serving also as a stopper 36. The nut body 37 is arranged inside the rail. Then, the catcher 35 arranged on the lower surface of the rail and the nut body 37 are fastened to the guide rail 1 by bolts 38. Roller stoppers (not shown) similar to those described above are also provided on both side ends of the lower guide rail 2 so that the steadying roller 7 can be engaged and captured. However, the roller stopper in this case has a nut body 37 formed in a flat plate shape.

In many cases, the left and right panel pairs engage and capture the runner 6 and the steady rest roller 7 located at both ends of the opening surface with the runner stopper 33 and the roller stopper as shown in FIG. By operating the door panels 3 adjacent at the center, each panel pair can be opened and closed. At this time, as shown in FIG. 6, the catcher 35 of the runner stopper 33 sandwiches the roller 31 in which the pair of elastic arms 34 are externally fitted on the rotating shaft 11 in the front and rear directions and in the groove 39 between the two elastic arms 34. The roller 31 is located. The groove 39 is formed horizontally long in the left and right directions, and the runner 6 can move left and right in the range. The reason is described below.

When the left and right panel pairs are stretched flush with each other to close the opening, the runners 6 located on both side ends are closed.
Of the body 12 is received by the stopper 36. The distance between the stoppers 36 at both ends is set smaller than the distance between the outer ends of the bodies 12 of the runners 6 located at both ends when the left and right panel pairs are stretched flush.
Therefore, when each panel pair is completely extended, the mounting portion 10 and the pivot shaft 11 move toward the stopper 36 while the body 12 is in contact with the stopper 36. That is, the block 15 slides relative to the body 12 while compressively deforming the spring 22. In order to allow this relative sliding, a groove 39 between the elastic arms 34 is formed horizontally long as shown in FIG.

In the state where the block 15 is slid as described above, unlike the case where the block 15 is received at the end of the lateral groove 14b, the tension of the spring 22 increases
It acts on the door panel 3 via 1. As a result, as shown by arrows in FIG. 1, each panel pair is moved toward the center of the opening surface by the force of the spring 22, and the side end surfaces of the adjacent door panels 3.3 are brought into close contact with each other. That is, in a state where the opening surface is closed by the left and right panel pairs, it is possible to prevent a gap from being generated between the panel pairs and improve the appearance of the folding door. The gap formed at the side end of the opening surface is not a problem because it is covered by a plate-shaped door cover as shown in FIG.

(Embodiment 2) FIG. 7 shows an embodiment 2 in which a part of the runner 6 is modified. The third embodiment differs from the first embodiment in that a dedicated roller shaft 41 that penetrates the body 12 back and forth is provided on the right side of the lateral groove 14b, and the roller 13 is rotatably supported by the roller shaft 41. Since the other components are the same, the same members are denoted by the same reference numerals and description thereof will be omitted. In the following embodiments, overlapping descriptions will be handled similarly. Although depending on the load acting on the runner 6, if the load is relatively light, the spring 22 can be directly received by the pivot shaft 11 without the block 15.

(Embodiment 3) FIG. 8 shows an embodiment 3 in which the runner 6 is of a four-wheel type. There, a pair of runner shafts 41 are provided near both left and right ends of the body 12, and the four rollers 13 are rotatably supported by the runner shafts 41. Then, a groove 14 is provided between both runner shafts 41, 41.
Is provided on the block 15 guided and supported by the groove 14.
1 were connected. In the third embodiment, the restraint plate 16 can be omitted.

(Embodiment 4) FIG. 9 shows an embodiment 4 in which the runner 6 is formed in a four-wheeled shape, similarly to the embodiment 3, and a contact member which slides on the upper surface of the body 12 relative to the body 12 is provided. A compression coil spring 22 is disposed between the body 12 and the contact body 42, and the spring 22
2 is urged to move away from the body 12. The contact body 42 is formed of an L-shaped plastic molded product, and its horizontal wall is slidably guided by a guide groove 43 provided in the body 12. Further, the slide groove 44 provided on the horizontal wall is guided and supported by the turning shaft 11. The vertical wall of the contact body 42 contacts the stopper 36 prior to the body 12, and moves the body 12 toward the center of the opening by the spring force of the spring 22 when the panel pair is fully extended.

In addition to the above, a tension spring can be used as the spring 22 instead of the compression spring. The mounting portion 10 of the runner 6 does not need to have the structure described in the embodiment. For example, the mounting portion 10 is attached by being inserted from the side end surface of the door panel 3 or an L-shaped metal fitting that covers the upper end surface of the door panel 3. It is possible to adopt a form or the like for preventing falling off, and the structure is not particularly limited. A folding door can be composed of two or more panel pairs.

[0032]

According to the present invention, a structure for removing a gap is added to the runner 6 itself so that the pair of panels when fully closed are brought into close contact with each other at the center of the opening surface.
-It has become possible to prevent the formation of a gap between the side ends of the third member. Therefore, compared with the case of using a special clearance remover,
The overall cost of the folding door can be reduced as much as the cost and labor of the construction can be reduced, and the appearance of the fully extended folding door can be improved. Since the clearance is removed on the side of the runner 6, even when the runner 6 and the runner stopper 33 are temporarily fixed, there is an advantage that the clearance facing the panel can be removed without any trouble.
