Description

[Detailed description of the invention] The present invention arranges a connecting plate 1 between a plurality of door panels 3, 3, respectively, and a cylindrical fitting part 2 provided on both sides of the connecting plate 1 over the entire length in the vertical direction. It is rotatably fitted into the fitted parts 4 provided alternately over the entire length of the upper and lower sides of each side end of the door panel 3 to rotatably connect the adjacent door panels 3, 3, and to be freely rotatable in a vertical plane. A shaft 12 having a round roller 11 and protruding vertically from the door roller 6 is rotatably attached to a horizontal fixed plate 13, and the fixed plate 13 is arranged at the lower end of every other connecting plate 1. Fastener insertion holes 17 provided on both sides of
Then, a fixing device 14 such as a screw is inserted into the cylindrical fitting part 2 of the connecting plate 1, and the door roller 6 is attached horizontally rotatably, and the door roller 6 is placed on a linear rail 5 laid on the floor etc. It relates to a folding door that engages rollers 11 in a rolling manner, and its purpose is to absorb the twisting force that acts between the connecting plate and the door roller during folding/opening/closing operations, and to smoothly move the door roller along the rail. To provide a folding door device that allows the vehicle to be driven.

In conventional folding doors in which door panels are rotatably connected to both sides of a connecting plate, the door roller is installed so that it cannot rotate horizontally with respect to the connecting plate, so there is a gap between the connecting plate and the door roller during the folding operation. Not only was the door roller not able to absorb the torsional force exerted on it, causing it to wear out on one side, making it impossible to run smoothly along the rail, it also had the disadvantage of a short lifespan.

The present invention solves these conventional drawbacks.

The present invention will be explained in detail below based on examples. The connecting plate 1 has a substantially U-shaped cross section, and cylindrical fitting portions 2 are provided at the tips of side pieces 7, 7 on both sides of the connecting plate 1, respectively.

Hollow caps 8 are attached to both ends of the door panel 3 over the entire length thereof.

The outer corner of the cap 8 is provided with a mating part 4 that opens obliquely outward and has a substantially 3/4 circular cross section. Caps 8 are respectively attached to both end portions of the door panel 3 so as to be located at opposite positions.

Therefore, a plurality of door panels 3 are arranged in parallel so that the fitted parts 4 of the caps 8 face each other, and the fitted parts 4, which open diagonally outward on the front side, face each other from the front side. The fitting portions 2, 2 on both sides of the connecting plate 1 are fitted into the opposing fitting portions 4, 4, respectively, and at the position where the fitting portions 4, 4 opening diagonally outward on the back side face each other, the back side Connecting plate 1 from the side
Fitted parts 4, 4 facing the fitting parts 2, 2 on both sides, respectively
A plurality of door panels 3 are connected so that they can be folded alternately into front and back by fitting into the door panels.

The door wheel 6 has a structure in which a roller 11 is attached between the leg pieces 10, 10 of a support plate 9, and the rollers 11 can be freely rotated in a vertical plane.
A fixing plate 13 is pivotally supported on a shaft 12 protruding from the center of the upper surface, and fixing tools 1 such as screws are attached to both sides of the fixing plate 13.
At 4.14, the door roller 6 is attached to the connecting plate 1 so as to be horizontally rotatable by fixing it to the lower ends of the fitting parts 2, 2 of every other connecting plate 1.

17 is a fastener insertion hole.

15 is a stationary end panel, and 16 is a movable end panel.

The folding door of the above structure is installed so that it can be opened and closed by removably engaging the rollers 11 of each door roller 6 on a linear rail 5 laid on the floor, etc., and is used, for example, as an opening/closing wall, a partition, etc. In FIG. 1, by moving the movable side end panel 16 left and right, each door car 6 is made to run left and right on the rail 5, and each door panel 3 is folded from front to back at each connecting plate 1. It is opened and closed.

During this folding/opening/closing operation, adjacent door panels 3, 3 connected to each other at the connecting plate 1 to which the door roller 6 is attached rotate as shown by arrows a in FIG. 2, but both The door panels 3, 3 do not always rotate by the same angle, but sometimes the left and right door panels 3, 3 do not rotate at the same angle (as shown by A in Figure 1), or only one door panel 3 rotates. There are times when the door moves (portion indicated by B in FIG. 1), and at such times, a horizontal rotational force, ie, a twisting force, acts between the connecting plate 1 and the door wheel 6.

When this twisting force acts, the door wheel 6 is engaged with the rail 5 and cannot rotate horizontally, so only the fixed plate 13 fixed to the connecting plate 1 rotates horizontally with respect to the shaft 12, and at the same time the door wheel 6
Only the connecting plate 1 rotates horizontally more independently, and as a result, the transmission of twisting force to the door roller 6 is absorbed, and the rail 5 is transferred to the door roller 6.
Only the running force in the left and right direction along the line will be transmitted.

As mentioned above, the present invention arranges a connecting plate between each of a plurality of door panels, rotatably connects the side ends of the adjacent door panels on both sides of the connecting plate, and rotates in a vertical plane. A door roller having a door roller is attached to the lower end of every other connecting plate so that it can rotate horizontally, and the roller of the door roller is removably engaged with a linear rail laid on the floor, etc., so that the roller of the door roller can rotate on the rail. The folding door can be opened and closed smoothly by moving the folding door, and since the door roller that runs along the rail is attached to the lower end of the connecting plate so that it can rotate horizontally, the connection between the connecting plate and the door roller when opening and closing the folding door. Even if a torsional force acts between them, the torsional force can be absorbed by the horizontal rotation of the connecting plate. Therefore, no horizontal rotational force is applied to the door roller, and only the running force along the rail is always applied to the door roller. It has the advantage of ensuring smooth running and a long service life without wear and tear.In addition, the shaft, which protrudes vertically from the door roller and has rollers that can rotate in a vertical plane, is rotatably attached to a horizontal fixed plate. At the same time, the fixed plate was fixed to the lower end of every other connecting plate and the door roller was attached so that it could rotate horizontally, so just by fixing the fixed plate with the door roller to the lower end of the connecting plate, the door roller could rotate freely horizontally. It is easy to attach and assemble, and has the advantage that the door roller rotates smoothly horizontally with respect to the fixed plate.

In addition, a fixing plate is provided at the lower end of the connecting plate, and a fixing device such as a screw is inserted into the cylindrical fitting part of the connecting plate through the fixing device insertion holes provided on both sides of the fixing plate, allowing the door roller to rotate freely horizontally. When installing the door roller, the door roller can be rotatably mounted by inserting a fixing tool such as a screw into the hole of the fitting part from the fixing tool insertion hole of the fixing plate. , The door roller can be easily attached using the hole in the fitting part, and the fixing plate can prevent the connecting plate from coming off upwards, and no special means for preventing it from coming off is required in this part. It is.
