In the panels 1a to 1d, the upper runners 13a to 13d are set to support a larger load than the lower runners 14a to 14d.
The panels 1a and 1b are rotatably connected via a hinge portion 15a, and the panels 1c and 1d are rotatably connected via a hinge portion 15b. Accordingly, when the panels 1a, 1b and 1c, 1d are rotated, the panels 1a-1d can be folded into one side of the upper rails 11a, 11b.

Next, the structure of the upper runners 13a to 13d will be described. Since the upper runners 13a to 13d have the same configuration, the configuration of the upper runner 13a will be described.
As shown in FIG. 2, FIG. 3 (a) and FIG. 3 (b), four wheels 17 are rotatably supported on the runner body 16 of the upper runner 13a. It rolls in a state where it cannot move up and down.

  The runner body 16 supports an upper end of a bolt 18 as a support member. An adjusting member 18 a is formed to protrude in the vicinity of the upper end of the bolt 18. The adjustment member 18a is formed in a flat hexagonal shape, and the bolt 18 can be rotated relative to the runner body 16 by rotating the adjustment member 18a.

Has been.

  The positioning convex portion 19b is formed to protrude in a cylindrical shape at the upper portion of the accommodating portion 19a, and the large diameter portion 19c is formed at the lower portion of the accommodating portion 19a. The nut case 19 formed in this way accommodates a nylon nut 20, and the bolt 18 is screwed to the nylon nut 20. The nut case 19 and the nylon nut 20 assembled in this way are rotated relative to the bolt 18 as the bolt 18 is rotated. The nut case 19 and the nylon nut 20 move up and down relative to the bolt 18 by rotating relative to the bolt 18.

  As shown in FIG. 5, the upper frame 2 a is formed of an extruded shape member, and includes side sides 21 and 22 and a connecting side 23 that connects the side sides 21 and 22. The connection side 23 is formed with a nut case hole 23a through which the nut case 19 is inserted at a substantially central position between both side sides 21 and 22, and screw holes 23b and 23c on both sides of the nut case hole 23a. The nut case hole 23 a is formed to have the same diameter as the large diameter portion 19 c of the nut case 19. The nut case hole 23a and the screw holes 23b and 23c are provided in the center of the side edges 21 and 22.

  The side sides 21 and 22 are provided with projections 21a and 22a as second engaging means that protrude so as to face each other above the connecting side 23. The protrusions 21 a and 22 a are formed over the entire length of both sides 21 and 22 in parallel with the connecting side 23.

  The upper frame 2a formed in this way is formed with engagement grooves 24 and 25 as engagement means facing each other on the inner peripheral surface, specifically between the projections 21a and 22a and the connecting side 23. ing.

The upper frame 2a is suspended and supported by the upper runner 13a via a support member and a runner base 26 as an engaging means.
As shown in FIG. 6A, the runner base 26 is composed of a long plate-like substrate 30 made of metal. Specifically, the runner base 26 is formed by bending the substrate 30, and FIG. 6A shows the runner base 26 before being bent as the substrate 30.

  A through hole 26 a through which the bolt 18 is penetrated is formed at the center in the longitudinal direction of the substrate 30. The substrate 30 is formed so that the periphery of the through hole 26a is slightly wider, and the width is set to be substantially equal to the inside of the side edges 21 and 22. Further, the outer edge of the substrate 30 in the vicinity of the through hole 26a is formed in a convex curved surface shape. Positioning holes 26b and 26c are formed at both ends of the substrate 30, respectively. The positions of the through hole 26a and the positioning holes 26b, 26c are formed corresponding to the positions of the nut case hole 23a and the screw holes 23b, 23c formed in the connecting side 23, and the centers thereof are on the same straight line. It arrange | positions so that it may be located.

  The width of both ends of the substrate 30 is set to the length Y1. The length Y1 is formed to be shorter than the distance Y2 (see FIG. 5) between the tips of the protrusions 21a and 22a. Engaging protrusions 26d and 26e as first engaging means protruding in the width direction are formed at both ends of the substrate 30, respectively. The engaging protrusions 26d and 26e protrude in opposite directions, and are formed in point symmetry with respect to the through hole 26a. The distance X between the leading edge of the engaging projections 26d, 26e and the center of the positioning holes 26b, 26c is formed to be equal to the distance between the screw holes 23b, 23c and the bottom surfaces of the engaging grooves 24, 25. ing.

The leading edges of both engaging projections 26d, 26e are set to be parallel to a straight line connecting the centers of the through hole 26a and the positioning holes 26b, 26c.
By bending the substrate 30 thus formed in a crank shape, an engagement recess 26f is formed, and a runner base 26 shown in FIGS. 6B and 6C is formed. The engaging recess 26f is formed to be slightly smaller than the outer shape of the accommodating portion 19a of the nut case 19.

  As shown in FIG. 3B, a runner base 26 is supported on the nut case 19 supported by the bolt 18. In the runner base 26, a positioning projection 19b is inserted into the through hole 26a above the nut case 19, and the bolt 18 is inserted through the positioning projection 19b.

  Then, with the engaging projections 26d and 26e engaged with the engaging grooves 24 and 25, the screws 27 and 28 as the engaging means and the positioning means are screwed into the screw holes 23b and 23c from the positioning holes 26b and 26c, respectively. Thus, the rotation of the runner base 26 relative to the upper frame 2a is prevented.

  In this state, the runner base 26 is supported by the nut case 19, and the upper frame 2 a is supported by the runner base 26. Therefore, the panel 1a is supported suspended from the upper runner 13a. In addition, the hanging height of the panel 1a can be adjusted by rotating the adjusting member 18a to relatively rotate the bolt 18, the nut case 19, the nylon nut 20, and the runner base 26.

Next, a procedure for attaching the upper runner configured as described above to the panel will be described.
First, as shown in FIG. 7A, the engaging protrusions 26d and 26e of the runner base 26 are inserted into the upper frame 2a so as not to contact the protrusions 21a and 22a of the upper frame 2a, and the nut case 19 is attached. It is inserted into a nut case hole 23 a formed in the connecting side 23.

  Next, the runner base 26 is rotated to engage the engaging protrusions 26d and 26e in the engaging grooves 24 and 25 as shown in FIGS. 2 and 7B. In this state, the positioning holes 26b and 26c of the runner base 26 are communicated with the screw holes 23b and 23c of the connecting side 23, respectively. In addition, since the leading edges of both engaging convex portions 26d and 26e are set to be parallel to a straight line connecting the centers of the through hole 26a and the positioning holes 26b and 26c, the engaging convex portions 26d and 26e The leading edge contacts the bottom surfaces of the engaging grooves 24 and 25 over the entire length thereof.

  When the screws 27 and 28 are screwed into the positioning holes 26b and 26c and the screw holes 23b and 23c from above, the runner base 26 and the upper frame 2a are assembled together, and finally the panel 1a is suspended from the upper rail 11a. Supported.

With the folding door configured as described above, the following operational effects can be obtained.
(1) The panel can be supported movably along the upper rail 11a.
(2) In a normal state, the runner base 26 can suspend and support the upper frame 2a and the panel 1a reliably by the engagement of the engagement convex portions 26d and 26e with the engagement grooves 24 and 25.

  (3) Screws 27 and 28 are screwed into the runner base 26 with the engaging projections 26d and 26e engaged with the engaging grooves 24 and 25. Therefore, even if the screw 27 or the screw 28 is loosened, it is possible to prevent the runner base 26 from rotating and maintain the engagement state between the engagement projections 26d and 26e and the projections 21a and 22a. Can be prevented.

  (4) The engaging protrusions 26d and 26e can be easily engaged in the engaging grooves 24 and 25 only by rotating the runner base 26 and the upper frame 2a relative to each other. Therefore, it is possible to easily prevent the panel 1a from falling.

  (5) The upper frame 2a can be assembled to the upper runner 13a from below. Therefore, it is not necessary to assemble the upper runner 13a from the end of the upper frame 2a, and the upper runner 13a and the upper frame 2a can be easily assembled. Moreover, when removing the upper runner 13a from the upper frame 2a, the upper runner 13a can be easily removed without moving it to the end of the upper frame 2a.

  (6) Protrusions 21a and 22a that engage with the engaging protrusions 26d and 26e of the runner base 26 are formed so as to protrude inward from each other, and support the upper frame 2a by suspending it from the appearance of the upper frame 2a. No mechanism appears. Therefore, the upper frame 2a can be suspended and supported on the runner base 26 without impairing the appearance of the upper frame 2a.

  (7) When the engaging projections 26d and 26e are engaged with the engaging grooves 24 and 25, the leading edges thereof are in contact with the bottom surfaces of the engaging grooves 24 and 25 over the entire length. Therefore, the overlap between the engaging projections 26d and 26e and the projections 21a and 22a can be increased, and the runner base 26 can reliably prevent the panel 1a from falling.

  (8) The engaging projections 26d and 26e are formed in point symmetry with respect to the through hole 26a. Therefore, by rotating the runner base 26 relative to the upper frame 2a, both the engaging convex portions 26d, 26e can be simultaneously engaged with the engaging grooves 24, 25. Therefore, the upper frame 2a can be easily suspended and supported on the runner base 26.

  (9) Since the engaging recess 26f is formed slightly smaller than the outer shape of the housing portion 19a of the nut case 19, the engaging recess 26f can hold the housing portion 19a. Accordingly, the nut case 19 can be inserted into the nut case hole 23a in a state where the nut case 19 and the engaging recess 26f are temporarily fixed, and the assembling work can be easily performed.

  (10) Bolts 18 are inserted through the through holes 26a of the runner base 26 through positioning convex portions 19b formed of synthetic resin. Therefore, the runner base 26 made of a metal plate and the bolt 18 are not in direct contact with each other, and generation of a squeak noise due to the rubbing of metals can be prevented.

  (11) In the runner base 26, the periphery of the through hole 26a is formed wide, and the width is set to be approximately equal to the distance between the side sides 21 and 22. Therefore, backlash between the runner base 26 and the sides 21 and 22 can be suppressed. Further, the strength of the rotation center of the runner base 26 can be increased.

  (12) Since the outer edge of the runner base 26 in the vicinity of the through hole 26a is formed in a convex curved shape, the runner base 26 does not get caught on both sides 21 and 22 when the runner base 26 is rotated relative to the upper frame 2a. It can be rotated smoothly.

  (13) The nut case hole 23 a is formed to have the same diameter as the large diameter portion 19 c of the nut case 19. Therefore, backlash between the nut case 19 and the upper frame 2a can be suppressed.

  (14) The nut case 19, the nylon nut 20, and the runner base 26 move up and down with respect to the bolt 18 by being rotated relative to the bolt 18. Therefore, the hanging height of the panel 1a can be easily adjusted by rotating the bolt 18.

You may implement the said embodiment in the following aspects.
-In above-mentioned embodiment, the screws 27 and 28 which penetrate the runner base 26 and the upper frame 2a were used as positioning means. However, the positioning means only needs to prevent relative rotation between the runner base 26 and the upper frame 2a and maintain the engagement state between the engagement convex portions 26d and 26e and the engagement grooves 24 and 25. Instead of the screws 27 and 28, pins or rivets may be used.

The technical ideas that can be grasped from the above embodiments are described below.
