Description

[Detailed description of the invention] The present invention relates to an opening/closing device for a double-folding door.The purpose of the invention is to bring the left and right doors, which are divided into two at the center due to the format of the door opening/closing mechanism, into abutment at the center while moving in an arc. The door type is commonly known as a double door, but in this type of door, the left and right door sections always move in an arc in the front of the door, so space for movement is essential. It is. It can also be understood that securing the above-mentioned movement space is an inherent drawback of double doors. For example, all Buddhist altars are opened and closed in the above-mentioned double-door style, but in order to eliminate the drawback of the movement space as much as possible, the left and right doors are further divided into two with hinges, and when viewed from the front when closed, there are four doors. This is dealt with by arranging the split doors in parallel. However, it is still necessary to ensure space for movement in front of the left and right doors. If it were installed in a room during use, this amount of space would not be a practical inconvenience, but during the production stage, many units were mounted on a workbench with small distances in the front and rear directions. At this point, the opening and closing mechanism must be adjusted. Alternatively, in cases where construction is desired inside, the door may not be able to be opened, causing inconvenience. In addition to these specific inconveniences, we aim to provide a new and innovative configuration in the sense that, for example, when the proposed door opening/closing device is used in a Buddhist altar, it brings new interest that has not existed in the past.

An embodiment of the present invention will be described with reference to the attached drawings. Reference numeral 1 is a box body whose front part can be opened, and left and right door parts 5, which are symmetrical with respect to the left and right side wall plates 2 and 2', are shown in FIG.
5' is installed. Due to the left-right symmetry, only the configuration of the left door portion 5 will be described for convenience.

Linear guide grooves 11 and 11' are bored on the left and right sides of the front edge of the ceiling plate 3 of the box body 1, respectively, and a guide plate 10 with a length extending to both the left and right ends is protruded.
The left and right door parts 5 have three split doors 6a to 6c that are horizontally connected in a bendable manner, and the split doors 6a, 6b
A hinge 9 is attached to the connecting portion between 6b and 6c from the back side. As shown in FIG. 1, in the closed position, the left half of the front part of the box body 1 is closed, presenting an L-shape when viewed from above.
For connection to the box body 1, the rear end of the split door 6c is swingably attached to the icicle surface 7 of the left side wall plate 2 with a hinge 8. 12 and 13 are the divided doors 6a to 6.
Guide groove 1 of the guide plate 10 only in 6a of c.
This is a regulating pin whose movement is restricted by engaging with 1, and is provided so that it can be attached and detached by screwing or fitting means.

The left and right door portions 5 have the above-mentioned configuration, and when the side end surfaces 14, which are the abutting surfaces of the split door 6a, are first pushed open to the left in a draw-like manner, the split door 6a moves into the guide groove 11 of the guide plate 10. , and at the same time, the adjacent door 6b is pushed and expands laterally using the hinge 8 as a fulcrum, while the door 6b itself begins to make a lateral rotational movement. The door 6a is opened as shown in FIG.
In the final open position, each of the divided doors 6a to 6c takes a U-shaped bent position and opens the front part of the box body 1. Next, the pins 12 and 13
To explain an example of the opening/closing operation when the latter pin 13 is removed, the divided doors 6a to 6c as shown in FIG. 4 can be opened further outward from the state shown in FIG. The split door 6a is bent in a V-shape, and the left and right sides of the split door 6a are opened in a V-shape. 4 is a bottom plate.

As described above, the present invention has a guide plate 10 that is longer than the front edge extending from the front edge of the box 1, and the guide plate 10 has guide plates on both sides of the center. Left and right symmetrical left and right doors are formed by horizontally connecting a plurality of divided doors 6a to 6c, respectively, and cover the side and front surfaces of the box 1. The outer ends of the outermost divided doors 6c of the sections 5, 5' are connected to the left and right side wall plates 2, 2' of the box body 1 via hinges 8, respectively, so as to be rotatable in the left and right direction, The linear guide groove 1 is provided at the inner end or both inner and outer ends of the upper part of the innermost divided doors 6a, 6a that collide with each other when the doors 5, 5' are closed.
Regulating pins 12 and 13 are engaged with pins 1 and 11', respectively.
Since this device is characterized by a protruding structure, it can be used as an opening/closing device for a double-folding door, and has the technical effect of preventing the door from moving toward the front during opening/closing operation, so the opening/closing device as described above can be used for Buddhist altars In such cases, it is an excellent and useful idea that not only improves workability in special situations such as manufacturing work or storage, but also adds new interest.
