Description

[Detailed description of the invention] The present invention relates to a traveling device for a folding door.
Wheels 2, 2 are attached to both sides of one end of the main body block 1, and a fitting recess 11 surrounded by a stepped surface 9 and a flange piece 10 is formed at the other end of the main body block 1. A substantially gate-shaped fitting bending piece 12 is extended to the plate, and this fitting bending piece 12 is fitted and attached to the fitting recess 11 of the main body block 1, and the plate extends downward from the main body block 1. A runner A is formed by the main body block 1 to which the wheel 2 is attached and the plate 3 to which the auxiliary wheel 4 is attached, and this runner A is attached to the upper end of the door panel 5.
The upper rail 6 is formed by extending running pieces 22.22 in opposing directions from both lower ends of the rail main body 21, which has a U-shaped cross section between the lower surfaces, and the wheels 2 are mounted on both running pieces 22.22. The main block 1 of the runner A is installed inside the upper rail 6 so that it can run freely, and the lower part of the plate 3 is made to protrude below the upper rail 6, and the secondary wheels 4 are attached to the lower side of one of the running pieces 22. This relates to a traveling device for a folding door facing the front.

A pair of door panels 5, 5 are foldably connected, runners A, A are attached to the upper surface of the end opposite to the connecting side of each door panel 5, 5, and these runners A, A are run freely inside the upper rail 6. In the folding door shown in Fig. 1, the pair of door panels 5, 5 can be opened and closed by folding and extending the pair of door panels 5, 5 by running the runners A, A on the upper rail 6. Runner A,
When the distance between A becomes narrower, the door panels 5, 5 tend to tilt around the respective runners A, A, as shown in FIG. Doing so may cause scratches on the door panel 5.
, 5 was difficult to run.

The present invention was developed in view of the above points, and is a folding device that can prevent the door panel from tilting even when the door panel is folded, and also allows the plate that supports the secondary wheels to be firmly attached to the main block without rattling. The purpose is to provide a door running device.

The present invention will be explained in detail below using examples.

Fig. 3 shows a runner A according to the present invention, in which wheels 2, 2 are mounted on both sides of one end of a main body block 1 formed of a molded resin material and a shaft protruding from the main body block 1. 7
, 7, and a mounting hole 8 opening at the top and bottom of the main body block 1 is bored in the center of a line connecting the shafts 7 and 7.

A fitting recess 11 is formed at the other end of the main body block 1 to be sandwiched between the step surface 9 and the collar piece 10, and a fixing hole 24 is formed in the fitting recess 11 vertically. is perforated.

Reference numeral 3 denotes a plate, which has a fitting bent piece 12 bent into a uniform shape at the upper part and a mounting piece 13 at the lower part.

Insert the shaft pin 15 into the shaft hole 14 of the mounting piece 13, pass the secondary wheel 4 through this shaft pin 15, and attach the retaining ring 1 to the tip of the shaft pin 15.
The secondary wheels 4 are attached to the plate 3 by fixing the wheels 6 with caulking or the like.

This plate 3 is constructed by fitting the fitting bent piece 12 into the fitting recess 11 of the main body block 1, and inserting the upper end of the bolt 19 inserted into the fixing hole 24 from below into the threaded hole 25 of the fitting bent piece 12. It is fixed to the main body block 1 by screwing.

By fitting the fitting bent piece 12 into the fitting recess 11 between the stepped surface 9 and the collar piece 10, the plate 3 is firmly fixed to the main body block 1 without wobbling or tilting. .

17 is a door stop rubber attached to the tip of the main body block 1.

The runner A formed as described above as shown in FIG. It is attached to the upper end surface of the end so that it can rotate freely horizontally.

As shown in FIG. 5, the upper rail 6 has a rail body 21 with a cross-sectional opening shape
A running piece 22.22 is extended from the lower end of the rail, and an auxiliary rail piece 26 having an auxiliary running piece 23 is hung from one lower end.The wheels 2, 2 are formed by extending the running piece 22. The auxiliary wheels 4 run on the auxiliary running piece 23 on the auxiliary running piece 22 .

In this case, even if a force F is applied to tilt the door panels 5, 5 when the pair of door panels 5, 5 are folded, the auxiliary wheels 4 will not move on the lower surface of the running piece 22 of the upper rail 6, as shown in FIG. This prevents the door panels 5, 5 from tilting.

Here, the runners A, A are attached to a pair of door panels 5, 5 such that the secondary wheels 4 are located inside or outside of each other.

FIG. 7 shows another embodiment of the present invention, in which a groove 28 is provided at the tip of the shaft 7 and the shaft pin 15, and an E-nong 29 is fitted into this groove 28 when installing the wheel 2 and the auxiliary wheel 4. This prevents the wheels 2 and auxiliary wheels 4 from being pulled out.

As described above, according to the present invention, even when the door panel is folded and the distance between the liners narrows due to the function of the secondary wheels, the door panel can be prevented from tilting, and the upper end surface of the door panel can be prevented from being scratched by rubbing against the upper rail. This can prevent the vehicle from becoming difficult to drive.

Furthermore, the plate supporting the secondary wheels is attached to the main block by fitting a fitting bent piece bent into a gate shape into a fitting recess surrounded by the stepped surface and the flange piece of the main body block. When fitted, the plate can be firmly attached to the main block without wobbling or tilting.
