Description

[Detailed description of the invention] Industrial field of application The present invention is a closure device used in lockers, cabinets, etc., specifically, a closing member that is joined at the center and closed, and is opened by sliding in opposite directions. The present invention relates to a switchgear equipped with a switchgear.

Conventional technology Conventionally, in this type of opening/closing device, the rear end of one of the two closure members and the front end of the other closure member are connected with a rope to interlock the closure members. (For example, see Japanese Utility Model Application Publication No. 175422/1983).

Problems that the invention aims to solve However, according to this method, the husband and wife select a closing member with a rope connected to the front end for opening, and a closing member with a rope connected to the rear end for closing. This was extremely troublesome.

Furthermore, the closing material is required to be guided along a rail bent rearward from the opening,
Coupled with the large coefficient of friction during opening and closing, the opening and closing operations lacked smoothness. Therefore, in order to assist the sliding of the closing material, we adopted a configuration in which the rope was pulled by a coil spring.
Not only does it require complicated calculations for the stroke and dimensions of the coil spring, but it also requires a large amount of installation space.

The present invention was devised to solve the problems of the prior art, and aims to provide a device that can be opened and closed without being constrained in direction by operating either of the two closing members. .

Means for Solving the Problems In the opening/closing device of the present invention, the base ends 8 and 11 attached to one end are joined at the center to the opening 2 of the main body 1 in which the guide rail 3 is provided facing each other. In a rocker, a cabinet, etc., equipped with two bendable closing members 6, 9 that are opened in the direction, guide rollers 4, 5 whose axes are arranged in the opposite direction of the guide rail 3 are installed at the front and rear corners of the main body 1. A sheave roller 13 is provided adjacent to the front guide roller 4, and the rear ends of the closing members 6, 9 are guided to the outside of the front guide roller 4, and a wire rope is attached to the 5 ends of the closing members 6, 9. 12, and the other ends are connected to the bases 11 and 8 of the other closure material stopper 6 through the outside of the rear guide roller 5 and sheave roller 13, respectively.

Function: Therefore, in the closed state, both closing members 6,
The base bodies 8 and 11 of 9 are joined at the center of the opening 2 to close the opening 2. When opening, the wire is removed by sliding one of the closing members 6 and 9 in the opening direction. The other closing members 9 and 6 connected by the rope 12 also slide in the opening direction, opening the opening 2 from the front. At this time, the rear end of the closing members 6, 9 is connected to the base 1 of the other closing member 9, 6.
The closure materials 6 and 9 are stored in the main body 1 by being pulled by a wire rope 12 connected to the closure materials 6 and 8 and pulled rearward through the front guide roller 4. If the closing members 6 and 9 are long, they are folded back from the outside of the rear guide roller 5 and the sealing members 6 and 9 are folded back from the outside of the rear guide roller 5.
It reaches between 3 and 3. Regarding closing,
When one of the closing members 6, 9 is slid in the closing direction, the other one is also moved, and the opening 2 is closed.

Embodiment An embodiment of the present invention will be explained below with reference to the drawings. 1 is a main body with an opening 2 formed on the front side, and a pair of left and right guide rails 3 are provided facing each other on the edge of the opening, and on the front and rear corners. Guide rollers 4 and 5 are attached with their axes disposed in the left-right direction, that is, in the direction opposite to the guide rail 3. Reference numeral 6 denotes a closing member whose both edges are slidably fitted into the guide rail 3 to close the upper half of the opening 2, and a base 8 having a handle 7 at its lower end.
are connected to each other, and the upper end portion is guided to the outside of the guide roller 4. Reference numeral 9 denotes a closing member whose both edges are slidably fitted into the guide rail 3 to close the lower half of the opening 2. The closing member 9 is connected to a base body 11 having a handle 10 at its upper end, and its lower end is attached to the front part. It is guided to the outside of the guide roller 4. Both of the closing members 6 and 9 join the base bodies 8 and 11 from above and below near the center of the opening 2 to close the opening 2. 12 are both closing members 6,
One end of the wire rope is connected to the base body 8 of the upper closure member 6, and the other end is connected to the base body 8 of the upper closure member 6 via the outer side of the sheave roller 13 provided adjacent to the lower front guide roller 4 and the rear guide roller 5. One end is connected to the rear end of the lower closing member 9, and one end is connected to the base body 11 of the lower closing member 9, and a sheave roller 13 and a rear guide roller are provided adjacent to the upper front guide roller 4. There are two types in which the other end is connected to the rear end of the upper closing member 9 through the outside of the opening 2, and the two closing members 6 and 9 are connected in an endless manner.
It will be stretched along the 14 is a lock, 15 is a top plate, and 16 is a base plate.

In the embodiment shown in the drawings, the main body 1 is vertically long, and the closing members 6 and 9 slide in the vertical direction, and the closing members 6 and 9 are stored in the upper and lower portions of the main body 1. A method is also conceivable in which the main body 1 is horizontally elongated and the closing members 6 and 9 slide laterally and are stored in the left and right portions. In addition, a wire rope 1 is attached to the rear guide roller 5.
Naturally, two guide grooves are provided.

Effects of the invention As mentioned above, the present invention connects the two closure members 6 and 9 and the two wire ropes 12 in an endless manner, so that it is possible to operate either of the two closure members 6 or 9. It can also be opened and closed, which eliminates the hassle of selecting a closing material each time it is opened or closed. Furthermore, since the two closing members 6 and 9 are guided by the guide rollers 4 and 5 installed at the front and rear of the main body 1, the coefficient of friction is small and they can be opened and closed smoothly.

In addition, since the connection is simply made using the wire rope 12, it can be constructed without requiring complicated calculations, and can be stored in a small space, resulting in an inexpensive product as a whole. It is useful as a switchgear for cabinets, etc.
