Description

[Detailed description of the invention] The present invention pivots a dimension-adjustable sleeve panel that is cut into the appropriate width dimension to the side frame of the mounting opening, and inserts a plurality of dimension-adjustable sleeve panels into the remaining opening of the mounting opening. A bi-fold door is arranged with runners installed at both the upper and lower ends of both side edges slidably locked to the upper rail and lower rail, respectively, and the central connecting part of each bi-fold door A latch body is provided that is removably latched to the rail, and the latch body is slidably latched to the upper rail or the lower rail, and is provided between each bifold door and between the bifold door and the dimension adjustment sleeve panel. This folding door device has a fitting protrusion and a fitting recess that fit into each other on the opposing side edges of the panel, and its purpose is to cut the size-adjustable sleeve panel into appropriate width dimensions. It can be installed with each bi-fold door of a constant width dimension, adjusting the dimensions within the installation opening, and when closed, the opening of each bi-fold door and the dimension adjustment sleeve of the bi-fold door and the dimension adjustment sleeve The fitting convex part and the fitting concave part fit together between the panels, and are locked to the latch body or rail of the bifold door,
It is partitioned off like a wall without shaking,
In addition, when opening, each bifold door and dimension adjustment sleeve panel can be opened and closed at any part for easy entry and exit, and can also be fully opened, and furthermore, the bifold door can be slid in the extended state like a sliding door. The bifold door can be opened and closed on both sides,
Although it is a bifold door that is easy to open and close, and can perform a variety of opening and closing operations, the fitting convex part and the fitting concave part allow it to function like a wall without wobbling with the dimension-adjustable sleeve panel. To provide a folding door device that can be closed from one side.

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

The folding door device shown in FIGS. 1 and 2 (A-A sectional view in FIG. 1) is an embodiment of the present invention. The dimension-adjustable sleeve panel 2 is pivotally mounted, and the two bifold doors 3 are mounted inside the remaining opening of the mounting opening, and the runners 5 provided on both side edges 4 and the upper and lower ends are connected to the upper rail 6 and the lower rail 7. A latch body 9 is provided at the upper end of the central connecting part 8 of each bifold door 3 to be detachably engaged with the upper rail 6. and fitting convex portions 10 that fit together on panel side edges 4 that face each other between the bifold door 3 and the dimension adjustment sleeve panel 2.
A fitting recess 11 is provided. The size-adjustable sleeve panel 2 is made of wood, and is cut into appropriate width dimensions using a saw 12, as shown in FIG. The upper rail 6 and the lower rail 7 are also connected via appropriate dimensional rail joints 15. As shown in FIG. 4 (an enlarged view of the main part of the B-B cross section in FIG. 1), the bifold door 3 has a runner 5 at the upper end rotatably locked on the upper rail 6, and a runner 5 at the lower end at the bottom. It is slidably engaged with the rail 7 and suspended so that it can be folded and slid open and closed. As shown in FIG. 5 (an enlarged view of the main part of the CC cross section in FIG. 1), the latch body 9 is projectingly provided at the upper end of the central connecting portion 8 of the bifold door 3.
It is elastically locked to the upper rail 6 in a detachable manner. As shown in FIG. 6 (an enlarged view of the D-D cross-sectional main part in FIG. 1), the upper and lower ends of the side edge 4 on the moving side of the dimension adjustment sleeve panel 2 are slid up and down to form an upper rail 6 and a lower rail. 7 are provided with lock pins 16 which are removably engaged with each other. As shown in FIGS. 7 and 8, the fitting protrusion 10 and the fitting recess 11 are formed by fitting a soft convex packing material 18 and a soft concave packing material 19 into a groove 17 formed in the panel side edge 4. It will be established as follows. In addition, in this embodiment, when the dimension adjustment sleeve panel 2 is pivotally attached to the opposite side frame portion 1', the upper and lower lock pins 16 are
, replace the soft concave packing material 19 on the panel side edge 4 with a soft convex packing material 18, and attach the dimension adjustment sleeve panel 2 upside down. Therefore, in this folding door device, the size-adjustable sleeve panel 2 is cut into appropriate width dimensions, and together with each bifold door 3 having a constant width dimension,
It can be installed with dimensions adapted to the installation opening, and when closed, each bifold door 3
The fitting protrusion 10 and the fitting recess 11 fit between the space and between the bifold door 3 and the dimension adjustment sleeve panel 2,
The latch body 9 at the upper end of the central connecting part 8 of the bifold door 3 is elastically locked to the upper rail 6, so that it is partitioned like a wall without rattling, and when opened, As shown in FIG. 2, any part of each bifold door 3 and the size-adjustable sleeve panel 2 can be opened and closed, making it easy to enter and exit, and can also be fully opened.

As mentioned above, the folding door device of the present invention can be installed by cutting the size-adjustable sleeve panel into appropriate width dimensions and fitting the dimensions within the installation opening together with each bifold door having a constant width dimension. Moreover, when the bifold door is closed, the fitting protrusion and the fitting recess fit between each bifold door and between the bifold door and the dimension adjustment sleeve panel, and the latch body of the bifold door fits into the rail. It locks and partitions into one wall like a wall without rattling, and when opening, it can be opened and closed from any part of each bifold door and size-adjustable sleeve panel, making it easy to enter and exit. You can also
The bifold door can be slid in an extended state like a sliding door, and can be opened and closed on both sides of the bifold door, making it easy to open and close. Although it is,
By fitting the fitting protrusion and the fitting recess, the size-adjusting sleeve panel and the size-adjusting sleeve panel can be closed together like a wall without wobbling.
