Description

[Detailed Description of the Invention] This invention relates to a door locking device for a cabinet, such as a large vending machine, which has two double door panels on the front.

This type of cabinet door locking device is easy to lock the door, is mechanically robust so that the door cannot be easily opened when locked, and is also designed to prevent objects inside the cabinet from being easily opened. For example, in vending machines, sufficient consideration must be given to serviceability during maintenance and inspection inside the machine, so that it does not become an obstacle during handling.

By the way, the general structure of this type of door locking device in the past is that a vertical support called a center pillar is fixed to the cabinet body side by superimposing them behind the tips of two door plates, and this support and each door plate are connected to each other. In between, each door is equipped with a key lock mechanism that locks the door by operating a key from the front. However, if the support is fixed in the center of the cabinet, the opening of the cabinet will be divided into two by the support, and the support will get in the way of maintenance and inspection inside the machine. It is desirable to be able to remove the struts from the viewpoint of serviceability when using the struts as guides. Furthermore, providing a key lock mechanism for each of the two doors makes managing and operating keys that much more troublesome, and from the standpoint of security against mischief, it is preferable to have fewer key lock mechanisms that can be operated from the outside.

The present invention has been made based on the above-mentioned conditions with the aim of providing a new door locking device that is satisfactory in terms of operability, safety, and serviceability.

The present invention will be described in detail below based on illustrated embodiments.

1 to 3, two door plates 2 and 3 are attached to the front surface of a cabinet body 1 of a vending machine side by side with hinges 4 interposed therebetween. Behind the door plates 2 and 3, a vertical center column 5 is arranged at a position spanning the front edges of the door plates 2 and 3, and between this column 5 and the cabinet body 1, and between the column and the column. A locking mechanism, which will be described later, is provided between the door 5 and the doors 2 and 3, respectively.

That is, a first locking mechanism 6 is provided between the support column 5 and the cabinet body 1 to detachably lock the support column 5 to the cabinet body 1. The locking mechanism 6 includes a latch plate 61 that protrudes above and below the column 5, a spring 62 that constantly protrudes and biases the latch plate 61 toward the locking position, and a spring 62 that retracts the latch plate 61 against the spring 62. It consists of a manually operated release lever 63 and latches 64 fixed at the top and bottom of the cabinet body facing the latch plate 61. Further, a second locking mechanism 7 is provided between the support column 5 and one of the door plates 2. The second lock mechanism 7 locks the door plate 2 to the support column 5 and is released by operation from inside the cabinet body 1. The locking mechanism 7 is provided independently of the first locking mechanism 6, and has the same structure as the locking mechanism 6. That is, it consists of a latch plate 71, a biasing spring 72, a release lever 73, and a stopper 74, and the stopper 74 is fixed to the back surface of the door plate 2. Furthermore, a well-known third locking mechanism 8 (see FIG. 2) is provided between the support column 5 and the other door 3, which locks the door by operating a key from the front. As shown in FIG. 3, a key lock hole 81 is provided in the side surface of the support column 5 for locking the hook of the key lock mechanism 8.

Next, the locking operation of the above configuration will be explained. Both the first and second locking mechanisms 6, 7 operate in the same way, and when the support column 5 or the door plate 2 is moved in the directions of arrows A and B in FIG. 71 are latched and automatically locked. If the release levers 63, 73 are manually operated in the directions of arrows C and D from the inside of the cabinet body, the latch plates 61,
71 moves back and comes off from the clasps 64 and 74. Note that the locking operation of the third locking mechanism 8 is well known and will be omitted here.

With the above configuration, in order to open the door plates 2 and 3, the door plate 3 is first unlocked by key operation, and then either of the lock mechanisms 6 and 7 is released from the inside of the cabinet body by operating the release lever. In this case, if the first locking mechanism 6 is released, the door plate 2 and the pillar 5 will be locked together.
If the second lock mechanism 7 is released, only the door plate 2 can be opened with the support column 5 remaining. Furthermore, first and second locking mechanisms 6 and 7
If both are released, the support column 5 can also be removed individually. Conversely, when closing the door plates 2 and 3, the above operation is performed in reverse, and finally the key lock mechanism 8 is locked by an external key operation.

As described above, according to the present invention, depending on the situation, such as simply opening the door or working inside the cabinet, the center support can be left on the side of the cabinet body, or it can be removed together with the door plate or separately. I can do it. Moreover, the locking mechanism that locks with key operation from the outside only needs to be placed in one location, making it possible to provide a door locking device with high practical value that improves not only operability and safety but also serviceability. .
