Description

[Detailed description of the invention] This invention relates to a device for connecting two adjacent door bodies in a folding door in which a plurality of door bodies formed of extruded sections are rotatably connected to each other. The simple structure makes it easy to replace and disassemble in the event of a failure after assembly and construction.
In addition, it has been devised to prevent gaps from forming in the connecting portions of each door body.

As is well known, in folding doors in which each door body is connected with a hinge, or in which the upper and lower ends of each door body are connected by a connecting plate, a gap is created at the connecting part of each door body, so special joints are required. It has been proposed to form a body and fit the door body onto a support shaft provided on the body.

Folding doors using this type of joint are easy to assemble, as the door body is inserted from the end of the spindle during assembly, but the door body often gets in the way during use. At this time, the door body can be pulled out from the joint body, but it is not possible to pull it out because it is supported by the ceiling, and there is the inconvenience of having to remove the entire folding door from within the frame before pulling it out.

This device was developed to solve this problem, and its feature is that the door body can be assembled by inserting it into the joint body from the side. An example will be explained with reference to the drawings.

The stile of the door body A and the joint body B are made of extruded aluminum alloy.As shown in Figure 2, the main body of the joint body B, the base 1, is formed into a thin rectangular cylinder shape, and the width is Door body A
The screw pockets 2, 2 are symmetrically provided at the ends of both wide surfaces 1a, 1a of the base 1, and the length is approximately the same as the height of the door body A. Wing pieces 3, 3 are provided protrudingly along an arc drawn around the screw pockets 2, 2 at the middle part of the wide surfaces 1a, 1a, and the tips of the wings 3 do not protrude beyond the end surface of the base 1. Further, a protrusion 4 is provided on the end face of the base 1 on the side where the screw pocket 2 is provided.

The vertical stile 5 of the door body A has protruding pieces 6 and 7 on both sides of the back surface, and a groove 8 between the two protruding pieces 6 and 7. One piece of the piece 9 is attached with a screw 11, and the other piece, the tongue piece 10, is provided to protrude in the direction of the groove 8.

The structure of connecting the door body A to the joint body B is as follows: screws 12 passed through the upper and lower tongue pieces 10 are screwed into the screw pockets 2, and the wing pieces 3 are inserted into the grooves 8 of the vertical stile 5. Door body A in condition
Of the two projecting pieces 6 and 7 that are rotatably attached to the joint body B and form the groove 8 of the vertical stile 5, the projecting piece 6 on the side facing the screw pocket 2 is the one shown in FIG. As shown, when the door body A is folded, it is formed to have a length close to the end face of the base 1, and the other projecting piece 7 is formed to be inclined so that its tip is close to the wing piece 3. be.

The base 1 of the joint body B is most preferably prismatic as described above, but it may also be prismatic without a hollow part, and the screw pocket 2 may be provided in the middle of the wide surface 1a. There is also.

Further, the door body A is preferably formed of a glass door or a flush door, and the screw 12 for attaching the tongue piece 10 to the joint body B preferably has a cylindrical part between the head and the screw part.

This invention has the above structure, and the door body A is centered around the screw 12 screwed into the screw pocket 2, and the related body B of the wing piece 3
It rotates in the direction of protruding more, for example, the door body A is rotated by 3
When connecting two panels in a row, the connecting devices on the left and right sides of the intermediate door body A are installed in opposite directions, and when the door body A is attached to the joint body B, the wing pieces are inserted into the groove 8 of the door body A. 3, pass the screw 12 through the tongue piece 10 protruding from the upper and lower ends of the door body A, and screw this into the screw pocket 2 to assemble the door.When disassembling the door, remove the screw 12 to close the door. Body A and joint body B are separated from each other.

As described above, the connecting device according to this invention has a screw pocket and a wing piece provided at the base of the joint body, a groove formed on the back surface of the vertical stile of the door body, and tongue pieces protruding from the upper and lower ends of the door body. Since the wing pieces are inserted into the groove and the upper and lower tongue pieces are connected to the joint body with screws, there is no need to insert the door body into the joint body from above and below, and it can be assembled from the left and right sides. This makes it extremely easy to assemble and disassemble, and since the wing pieces are put into the grooves and assembled, there is no risk of gaps occurring in the connecting parts, and the appearance is very good. .

Furthermore, one of the projecting pieces forming the concave groove of the vertical stile is inclined toward the wing piece, and the tip of the projecting piece is close to the wing piece, so that when the door body is folded and closed, the joint body is There is no risk of fingers being inserted between the base and the door body, and it also has the effect of increasing stability.
