Description

[Detailed Description of the Invention] 3-1 Purpose of the Invention 3-1-1 Field of Industrial Application The present invention relates to a locking device for a cabinet and at the same time to an overturn prevention device for the cabinet.

3-1-2 Prior Art Conventionally, locking devices for cabinets have been disclosed, for example, in Japanese Utility Model Publication No. 52-29716 and Japanese Utility Model Publication No. 58-58.
There are ideas such as No. 153665, but what is seen in these publications is only a mechanism in which when a desired extractor is opened, an interlocking plate is activated and the other extractors are automatically locked. There was a drawback that the board could not be reliably locked into the locking state to prevent it from falling over.

3-1-3 Problems to be solved by the invention Therefore, the present invention eliminates the above-mentioned drawbacks of the conventional cabinet, and when one extractor is used, it ensures locking of the other extractor and prevents it from falling over. The purpose is to make the use of the cabinet safe and easy to handle at all times.

3-2 Structure of the invention 3-2-1 Means for solving the problem The invention consists of the following means.

An interlocking plate having stopper pins of the same number as the number of extractors protruding at intervals is installed at appropriate positions on the side of the cabinet body so as to be movable up and down, and inclined grooves and concave grooves facing the stopper pins are provided on the side of the extractor body. A lock member is provided, a lever is provided protruding from an opening provided on the upper side of the interlocking plate, a crank rod is connected to a cylinder lock provided on the front surface of the cabinet body, and a bent portion of the crank rod is provided. An interlocking plate member is provided in the opening of the interlocking plate material so as to be brought into contact with and separated from the lever, and a long groove and a concave groove are provided on both left and right side surfaces of the interlocking plate material, and the interlocking plate member is composed of a ball and a pressing bullet that come into contact with and separate from the grooves. A stop member is provided.

3-2-2 Example An example of the configuration of the present invention is as follows.

Reference numeral 1 denotes a cabinet main body, and a space 2 formed vertically at a suitable position on the inner surface of the main body has a cross-sectional shape in which stopper pins 4 . Interlocking plate material 5 consisting of
Install it so that it can move up and down. 6... is a locking member provided on the side surface of the extraction body 3, and this locking member is located in the inclined groove 7 facing the stopper pin 4.
It consists of a concave groove 8 with a . 9 is the interlocking plate material 5
An opening is cut out in the upper side of the back surface of the lever 10, and a lever 10 is provided in this opening to project outward. Reference numeral 11 denotes a cylinder lock provided on the upper front side of the side plate 1' of the cabinet body. Try to keep them apart. 1
Reference numerals 3 and 13 designate interlocking plate locking members provided at appropriate locations outside the left and right sides of the interlocking plate 5, and this locking member consists of a ball 14 and a bullet 15 that presses the ball from inside. Numerals 16 and 16 are long grooves provided at appropriate positions on both left and right side surfaces of the interlocking plate 5, and the ball 14 engages with these long grooves to move up and down. Furthermore, grooves 17, 17 are provided directly above the long grooves 16, 16, in which the balls 14 engage and do not move. 18 is a front side plate of the extraction body 3.

3-2-3 Action First, operate the cylinder lock 11 to lock the crank rod 1.
Rotate 2. Then, the bent portion of the crank rod 12 comes into contact with the lower surface of the lever 10 and pushes it up, so that the interlocking plate 5 rises. At this time, the stopper pin 4 moves out of the passing position relative to the lock member 6 and rises, and is now in a locked state (all locked). (See Fig. 4 → Fig. 5) Next, when this all lock is released and the body 3 is pulled out from the closed state, the stopper pin 4 is moved from the locking member 6. As it passes through the concave groove 8, it descends by the inclined groove 7. At this time, the lock member 6 and the stopper pin 4 are attached to another extraction body 3 in the same positional relationship.
Also, since the stopper pin 4 descends,
The locking member moves out of its passing position and becomes locked (see FIG. 6). Therefore, the extractor body 3 is opened at only one place, and all the other extractor bodies 3 remain locked, so that overturning is prevented.

At this time, the interlocking plate locking member 13 installed to keep the stopper pin 4 in the locked state,
The stopper pin 4 is moved out of the position of the long grooves 16, 16 for positioning it in the passing state, and moved to the position of the upper concave grooves 17, 17 for positioning the other extraction body 3 in the state of automatic locking. The state will be maintained.

Furthermore, by closing the extracted extraction body 3, the interlocking plate 5 is
Since the stopper pin 4 returns to its original position, the stopper pin 4 also returns to the position where the locking member 6 passes, and all the extraction bodies 3 become free.

3-3 Effects of the invention Since the invention consists of the above-mentioned configuration, it is possible to achieve the following effects.

It is possible to ensure that all extraction bodies are completely locked in various cabinets, and to ensure that the extraction body is prevented from falling when pulled out.

This fall prevention is achieved by pressing and locking the locking member consisting of the ball and the bullet from both the left and right sides of the interlocking plate, and by making the movement of the interlocking plate into the locking position a ``descent'', the effect of its own weight is also achieved. Since this is added, reliability can be further increased.

Furthermore, the position of contact between the stopper pin and the lock member in the locked state is set at the top of the lock member in the all-lock state, and at the bottom of the lock member when the desired extraction body is opened and the other extraction bodies are locked. Since they are used separately, displacement of the lock member can be alleviated.
