Description

[Detailed Description of the Invention] The present invention has a plurality of bifold doors and runners provided at both the upper and lower ends of both sides of the door, which are slidably locked to the rails of the upper and lower frame parts of the construction opening. A lock body is provided between the runners on both sides of the bifold door, and a lock receiver to which the lock body is removably locked is attached to the rail. Regarding a folding door device that can be slid freely and fixed at an appropriate position, when the lock body is removed from the lock receiver, the bifold door can be opened and closed freely by folding, and the lock body is attached to the slideable lock receiver. When locked to the body, the bifold door can be extended and slid freely open and closed like a sliding door, and when the lock body is locked to the fixed lock receiver, the bifold door cannot be extended. When the door is fixed like a wing wall, and the lock receiver is fixed against one of the runners, the bifold door can be opened and closed freely by folding with one side edge as the fixed rotation axis. This is a completely new folding door device that can be used in many ways as an indoor partition fitting.

Hereinafter, the present invention will be explained based on the drawings.

The folding door device shown in Fig. 1, Fig. 2 (X-X sectional view in Fig. 1) and Fig. 3 (Y-Y sectional view in Fig. 1) is an embodiment of the present invention. The bi-folding door 1 is constructed by slidably locking the runners 2, 2' provided at the upper and lower ends of both side edges to the rails 3, 3' of the upper frame and lower frame of the construction opening, respectively. A lock body 4 is provided between the runners 2' at the lower ends of both side edges of the bifold door 1, and the lock body 4 is removably engaged with the lock receiver 5. , rail 3'
It is provided so that it can be slid freely and fixed at an appropriate position. As shown in FIG. 4, the bi-folding door 1 is made up of a pair of wooden panels 6 that are foldably connected by a connector 7, and is suspended within a construction opening. The lock body 4 is pin-shaped and is housed in a storage part 8 provided at the lower end of the connector 7 of the bifold door 1 so as to be able to slide up and down. A fitting recess 1 is slid up and down, and a fitting protrusion 10 formed at the upper end of the fitting recess 1 is formed at the upper end of the storage section 8.
1 and can be removably fitted to the top of the holder. As shown in FIGS. 5, 6, and 7, the lock receiver 5 to which the lock body 4 is removably locked is slidably engaged with the rail 3', and is attached to the rail 3' by a screw 12 as necessary. It is fixed to 3' and is made of synthetic resin so that it can be easily rubbed.
The lock body 4 is locked in the locking recess 13. Further, a latch body 14 is provided at the upper end of the connector 7 and is detachably and elastically engaged with the rail 3 of the upper frame.
When the latch body 14 is extended, it is elastically latched to the rail 3 to keep the bifold door 1 stationary in the extended state, and the latch body 14 is also slidable while being elastically latched to the rail 3. be. Therefore, in this folding door device, when the lock body 4 is removed from the lock receiver 5, as shown in FIG. As shown in FIG. 8, the bifold door 1 can be freely folded and opened and closed, and when the lock body 4 is locked in the slidable lock receiver 5 as shown in FIG. , the bifold door 1 can be slid open and closed like a sliding door while being extended, and when the lock body 4 is locked to the fixed lock receiver 5 as shown in FIG. As shown in FIG. 1, the bifold door 1 is extended and fixed like a wing wall, and as shown in FIG. As shown on the right side in Figure 10, the bifold door 1 is foldable and openable with one side edge as a fixed rotating shaft, and can be easily adapted to many uses as an indoor partition fitting. .

In addition, in the folding door device of the present invention, the number of folding doors disposed within the installation opening is not limited, and the lock body may be provided at either the upper end or the lower end of the bifold door. In addition, the shape and material of the bifold door and other members are not limited to those of the above embodiments, and the folding door device of the present invention This may be implemented at the front opening of a closet or other storage section.

As described above, the folding door device of the present invention has a plurality of bifold doors, in which runners provided at both the upper and lower ends of both side edges are slidably engaged with the rails of the upper and lower frame parts of the installation opening. a lock receiver which is arranged in a construction opening so that it can be folded and slid open and closed, a lock body is provided between runners on both side edges of the bifold door, and the lock body is removably locked;
Since it is provided so that it can slide freely on the rail and can be fixed at an appropriate position, it is easy to attach and detach the lock body to the lock receiver, or fix the lock receiver to the rail and make it slidable. Depending on the operation, the bifold door can be changed into various forms such as a form that can be folded and opened and closed freely, a form that can be slid open and closed like a sliding door when it is extended, a form that is fixed when it is extended like a wing wall, etc. This is a completely new folding door device that can be used in many ways as an indoor partition fitting.
