Description

[Detailed explanation of the idea] This invention features a bifold mechanism in the center that allows you to freely play new songs.

A runner is provided at each corner of the face piece, and a track rail is provided at the corresponding edge of the rectangular opening, and the runner is slidably engaged with the track rail, thereby forming the face piece into the rectangular opening. The back side of a door plate with approximately the same dimensions as the face piece is pivotally attached to the center bent top of the face piece, and locking parts are provided on both sides of the center of the back side of the door. This is a door opening/closing structure in which locking receiving parts which are detachably engaged with the parts are provided on both sides of the central curved top part of the face piece, and can be easily changed to either opening.

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

The door opening/closing structure shown in FIGS. 1 and 2 is an embodiment of the present invention, in which pin-shaped runners 3 are installed at the top and bottom corners of the face piece 1, which has a bifold mechanism that can be bent freely at the center. 3' is provided,
On the other hand, groove-shaped track rails 6.6' are provided on the upper and lower corresponding edges 5, 5' of the rectangular opening 4, and the track rails 6.6 are provided with groove-shaped track rails 6.6'.
' by slidably engaging the runners 3, 3',
The face piece 1 is foldably attached to the rectangular opening 4, and the face piece 1
A rear center portion 9 of a door plate 8 having approximately the same dimensions as the face piece 1 is pivotally attached to the central bent top portion 7 of the door plate 8, and locking portions 10, 10' ( The upper edge of the door plate 8 serves as a locking part 10.10'), and a locking receiving part 11.11' that removably engages with the locking part 10.10' is folded in the center of the face piece 1. These are provided on both sides of the curved top portion 7, respectively.

The facepiece 1 is made up of a pair of panels 12.12' connected by pivots 13.13' at both upper and lower side edges, and a door plate 8 is attached to the central bent top 7 of the facepiece 1. When pivoting the back center portion 9, the upper and lower pivots 13.1
Pivot supports 14 and 14' attached to both upper and lower ends of the back center portion 9 of the door plate 8 are rotatably connected to the door plate 3'.

Also, the upper edge of the door plate 8 is used as the locking part 10°10', but the locking receiving part 11.11' is rotated at the upper edge of both panels 12.12' of the face piece 1. It is a freely pivoted L-shaped piece, and the locking receiving part 11.11' rotates as shown in FIG. It engages removably.

Therefore, in this embodiment, as shown in FIG. 4, when the locking portion 10 and the locking receiving portion 11 are engaged, the door plate 8 is integrated with one panel 12, and the face piece 1 is folded. As shown in FIG. 5, when the locking part 10' and the locking receiving part 11' are engaged, the door plate 8 becomes one with the other panel 12'. When the face piece 1 is folded, it is pushed to the right side and opened, contrary to the above-described structure, so that it can be easily opened from the left to the right.

In addition, in the present invention, as in the embodiment shown in FIGS. 6 and 7, the face piece 1 may be formed of only two pairs of upper and lower horizontal bar pieces 15 and 15'; in this case, One end of each of the horizontal bar piece 15 and the horizontal bar piece 15' is rotatably connected to each other, and the connecting part (center bent top part 7) is pivotally attached to both upper and lower ends of the back center part 9 of the door plate 8. ing.

In addition, the upper horizontal bar piece 15 is substituted for the locking receiving part 11.11', but the locking part 10.10' is a fishhook-shaped piece attached to the back surface of the door plate 8 so that it can swing freely. be.

Therefore, in this embodiment as well, as shown in FIGS. 8 and 9, left and right handing can be easily performed by attaching and detaching the locking parts 10 and 10' and the locking receivers 11 and 11'. Even if it is opened by the same operation as above, the rectangular opening 4 is opened without being obstructed by the face piece 1.

In this embodiment, the upper runner 3 is formed as a transfer support roller, the lower runner 3' is formed as a guide roller, and the upper runner 3 is formed as a transfer support roller.
The face piece 1 and the door plate 8 are supported downwardly by being removably locked to the base plate.

Further, in the present invention, the door plate may be opened and closed from side to side or vertically.

As mentioned above, the door opening/closing structure of the present invention has a runner at each corner of the face piece which has a bifold mechanism that can be bent freely at the center, and tracks on the corresponding edges of the rectangular opening. A rail is provided, the runner is slidably engaged with the track rail, the face piece is foldably attached to the rectangular opening, and the back side of a door plate having approximately the same dimensions as the face piece is attached to the center bent top of the face piece. The central part is pivoted, locking parts are provided on both sides of the center part of the back surface of the door plate, and locking receiving parts that removably engage with the locking parts are provided on both sides of the central bent top of the facepiece. Because it is provided with a locking part and a locking receiving part on either side, the door plate is integrated with either half of the facepiece, and the facepiece can be opened and closed by folding or stretching it. It can be easily changed to either opening by changing the locking part and the locking receiving part to be engaged.
