DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the embodiments shown in the drawings. In this specification, the front means the front side of FIG. 1, the rear means the back side, the left means the left side of FIG. 1, and the right means the right side of FIG. As shown in FIGS. 1 to 3, the folding door device 1 is a frame body composed of a pair of left and right vertical frame members 2 and a pair of upper and lower guide rails 3 and 4 which are provided at the upper and lower ends of these vertical frame members 2. 5, and at least one folding door 6 is guided to the frame body 5 so as to be openable and closable as follows. That is, the guide rail 3 arranged on the upper side of the frame 5 has a front rail 21 projecting rearward, and a rear rail 20 opposing the front rail 21 at a predetermined interval and projecting forward in parallel therewith. is doing. And the above folding door 6
Has a pair of folding door constituting members 10 and 11 connected by required hinges 7, and the left folding door constituting member 10
On the left side of the upper end of the
2, a rear slider 14 is horizontally swingably provided, and a front slider 15 is horizontally swingably provided at a right upper end portion of the right folding door constituting member 11 by a bolt 13 with its axis centered vertically. (See Figure 4).
A pair of right and left rollers 16 are rotatably provided on the rear surface of the rear slider 14, and these rollers 16 are mounted on the rear rail 20. On the other hand, the front slider 15
A pair of left and right rollers 17 are rotatably provided on the front surface of the roller, and these rollers 17 are mounted on the front rail 21. These rear slider 14 and front slider 1
5 is slightly shifted in the front-rear direction, so that even if they slide left and right along the rear rail 20 and the front rail 21, they do not collide with each other and interfere with each other. It can be moved (see Fig. 5). With such a configuration, the folding door constituent members 10 and 11 can be folded to a state in which they are parallel to each other. Pins 9 project downwardly from the lower left side portion of the left folding door constituting member 10 and the lower right side portion of the right folding door constituting member 11 so as to be concentric with the axial centers of the bolts 12 and 13, respectively. The pin 9 is guided in the groove of the guide rail 4 arranged on the lower side.

As shown in FIGS. 3 and 4, the upper guide rail 3 is provided with a groove 23 that opens downward, further to the rear side than the rear rail 20, and a pair of left and right grooves are formed in the groove 23. A sliding piece 24 is fitted so as to be slidable left and right.
Each of the sliding pieces 24 is rotatably held by a pivot pin 25 which is attached to the lower surface of the sliding piece 24 so as to rotatably support a leg end of a spring 26 having both legs projecting obliquely rearward about the coil. ing. That is, the spring 26 is installed between the sliding pieces 24 so as to connect the sliding pieces 24 to each other. On the other hand, on the left side of the upper end of the left folding door component 10, a movement blocking piece 30 having notches 31 that are opened in the upper and lower sides and the rear side is provided by the bolt 12 to the rear slider 14.
It is mounted so that it can be horizontally swung together therewith, and the left pivot pin 25 and the leg projecting end are fitted in the notches 31 of the movement blocking piece 30. In addition, in the movement preventing piece 30, the right side wall (left side in FIG. 4) of the notch 31 is vertically bifurcated, and the leg portion of the spring 26 can horizontally swing between the crotches (see FIG. 5). ). On the other hand, a pressing piece 32 having a contact surface 33 on the left end face is attached to the right end portion of the upper end of the folding door component member 11 on the right side by a bolt 13 so as to horizontally turn together with the front slider 15. When the front slider 15 and the rear slider 14 approach each other by folding the folding door constituent members 10 and 11,
The abutment surface 33 of the pressing piece 32 comes into contact with the pivot pin 25 on the right side and the leg projecting end and presses it to the left side to compress the spring 26 (see FIGS. 2 and 5). for that reason,
This spring 26 is formed by folding the folding door component members 10, 1.
1 urges each other in the direction of development.

As shown in FIG. 2, at the upper ends of the connecting portions of the folding door constituting members 10 and 11, pivot pins 35 are provided so as to project upward toward the respective front edge portions, and these pivot pins 35 are provided. On the other hand, each leg tip end of the spring 40, which has two left and right coil portions and whose leg portions project from the outside toward the front, is rotatably held. The spring 40 has a shape in which both legs are opened in the left-right direction when a spring force is not applied (in a removed state). That is, at the time of mounting, since both legs are narrowed in the direction of mutual proximity, a spring force acts so as to widen the mutual interval of both pivotally supporting pins 35, whereby the folding door constituting members 10, 11 are attached in the direction of folding. It will receive power. However, this spring 4
0 is formed so that the spring force is weaker than that of the spring 26, and when the pressing piece 32 provided in the folding door constituting member 11 comes into contact with the right leg projection end of the spring 26 (approximately). , About 80% of the effective frontage is opened so that even a small article can be sufficiently passed even in this state, the folding of the folding door constituting members 10 and 11 is stopped. At this time, there is an effect that the folding door constituent members 10 and 11 can obtain a stable state without shaking. By the action of the spring 40 as described above, the folding door constituting members 10, 11
1 and 6, the lock bar 41 is provided on the lower left side of the front of the folding door component 11 on the right side with respect to the guide rail 4 on the lower side, as shown in FIGS. 1 and 6. There is provided a lock mechanism 42 having an appropriate structure that can be fitted and removed. In the illustrated lock mechanism 42, 43 is an operation rod connected to the lock rod 41, 44 is a position holding socket for the operation rod 43, and 45 is a spring for biasing the socket 44 toward the folding door component member 11 side. And 46 is a counterbore part into which the socket 44 is fitted. Of course, the folding door constituting member 11 is formed with vertically long holes and slits that allow the lock rod 41 and the operating rod 46 to move up and down.

As shown in FIG. 2, a lock arm 50 is horizontally swingably provided at a predetermined height position on the rear surface of the vertical frame member 2 on the left side of the frame body 5. As shown in FIG. 5, when the folding arms constituting members 10 and 11 are folded into a state in which the folding arms constituting the lock arm 50 are parallel to each other, the J-shaped bent tip portion can engage with the folding door constituting member 11 on the right side. Has become.

[0010]

[How to use the embodiment] Next, how to use the embodiment will be described. When the locking mechanism 42 is released (the socket 44 is fitted in the upper counterbore portion 46) in a state where the folding door constituting members 10 and 11 are deployed in a straight line as shown in FIG. 1, the action of the spring 40 causes the folding door constituting members. 10 and 11 are folded to a position where the mutual V-shape is formed. After that, double folding door component 1
The right folding door constituting member 11 is pushed to the left side until the 0 and 11 are parallel to each other (see FIG. 5), and the locking arm 50 is engaged with the folding door constituting member 11. As a result, the frontage is fully opened, and at the same time, the spring 26 stores an urging force. When the front door is in the fully opened state and the engagement by the lock arm 50 is released, the double folding door constituting members 10 and 11 are expanded at a stretch by the action of the spring 26. Then, the locking mechanism 42 is set (the socket 44 is fitted into the lower counterbore portion 46) while assisting the unfolded state to some extent by hand.

In the present invention, it is needless to say that a plurality of folding doors 6 may be provided in one frame body 5.
