Description

[Detailed Description of the Invention] The present invention relates to a folding door whose rotation axis can be easily changed and the direction of the door can be easily changed.

Previously, the structure was such that the rotating shaft could be attached to either the left or right door body in response to changing the hand of the folding door.
Disclosed in the issue. However, in the former case, the structure of the pivot tool attached to the pivot side of the door body and the sliding tool attached to the open side are slightly different (a door wheel is attached to the sliding tool), so when replacing the door wheel, Replacement work is required and changing work is troublesome. In addition, in the latter case, guide rollers are provided at the upper ends of the left and right stiles of the folding door, and a door wheel is provided at the lower end, and the guide roller and door wheel, which serve as the rotation axis of the folding door, are fixed by an upper stopper and a lower stopper, respectively. This has the disadvantage that separate members such as an upper stopper and a lower stopper are required, which increases the number of parts and increases the cost accordingly.

This invention was made with attention to the above points,
To provide a folding door whose rotation axis can be easily changed and the number of parts is minimized.

Embodiments of the present invention will be described below with reference to the drawings.
In Fig. 1, the door frame 1 is connected to the upper frame 2 and the vertical frames 3, 3.
and a lower frame 4, and a folding door A is attached to this door frame 1. The folding door A consists of left and right door bodies A1 and A2 of the same structure and same dimensions, and the left and right door bodies A1,
A2 is composed of an upper stile 5, vertical stile 6a, 6b, 6a', 6b', lower stile 7, middle stile 8, etc., and has left and right door bodies A1, A2.
Adjacent central vertical frames 6b, 6b are foldably connected by a connecting mechanism 9. Said left door body A
An upper door body B1 and a lower door body B1' are attached to the upper and lower ends of the left stile 6a of No. 1, respectively, and an upper door body B2 and a lower door body B1' are attached to the upper and lower ends of the right stile 6a' of the right door body A2, respectively. A vehicle body B2' is attached. Each upper door body B1 and B2 have the same structure,
Figures 6a and 6b show details of the upper door car bodies B1 and B2. In the figure, a sleeve 10 has a circular hole 10a inside, the outer periphery is similar to the hollow part 21 of the vertical frames 6a, 6a', and a flange 11 is provided at the upper end. A substantially cylindrical guide member 14 having leg portions 12 at the bottom and guide grooves 13 at the top is slidably and rotatably fitted into the sleeve 10 . The leg portion 12
A spring 15 is attached to the guide member 14 to bias the guide member 14 in the direction of protruding from the sleeve 10. A wheel 16 is attached to the guide groove 13 via a shaft 17. Furthermore, a through hole 18 is formed near the upper end of the guide member 14 and located above the wheel 16 .

The lower door body B1' and B2' have the same structure, in that a protrusion 14a is formed at the lower end of the guide member 14, and the protrusion 14a abuts the flange 11, and that the spring 15 is not provided. Only the upper door car bodies B1 and B2 are different.

The sleeves 10 of each of the door body bodies B1, B1', B2, B2' are fitted into the upper and lower ends of each of the stiles 6a, 6a', and the flanges 11 are brought into contact with the end faces of the stiles, whereby the door bodies can be attached. When installing the folding door A in the door frame 1, attach the lower door body B1', B to the rail 4a of the lower frame 4.
Then, the guide members 14 of the upper door car bodies B1 and B2 are engaged with the rails 2a of the upper frame 2. In that case, the guide members 14 of the upper door car bodies B1 and B2 are pushed into the sleeve 10 by hand or with a jig, and when the folding door is housed in the door frame 1, the guide member 14 is released from the guide member 14 by the spring 15. moves upward, and the guide groove 13 and the rail 2a engage with each other.

An upper door body B1 and a lower door body B are located on the rotation axis side of the folding door A, that is, on the left side in the illustrated embodiment.
1' indicates that the screw 19 is inserted into the through hole 18 of the guide member 14.
The guide member 14 and the rail 2 are inserted into the through hole 20 (FIG. 4) formed in the rail 2a.
a and 4a are fixed. As a result, when the folding door is opened from the opening side (right side), the vertical stile 6a rotates together with the sleeve 10 about the guide member 14 of the upper and lower door body B1, B1' as a support shaft. If you want to change the rotation axis to the right side, remove screw 19 and remove the right side upper and lower door body B.
2, the guide member 14 of B2' may be fixed in the same manner. Therefore, the rails 2a of the upper and lower frames 2 and 4,
Through holes 20 are formed in 4a at symmetrical positions. Note that a pin may be used instead of the screw 19 described above.

As described above, according to the present invention, the rotating shaft can be configured by simply inserting screws or pins into the through holes of the guide member and the through holes of the rail, and the rotating shaft can be changed when changing the hand. This is extremely easy to do, and even when changing the rotation axis, there is no need to make any changes to the door body, and the change can be made with only screws or pins, so the cost is almost negligible.
