Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawer type cabinet in which a plurality of drawers vertically arranged in a vertical direction in a main body of a cabinet cannot be simultaneously drawn out to prevent falling.

[0002]

2. Description of the Related Art Conventionally, as a cabinet of this type,
For example, it is disclosed in Japanese Patent Laid-Open No. 10-327954.

In such a cabinet, a drawer locking / unlocking device is often provided because of problems in managing documents to be stored. As such a locking / unlocking device, a manual type locking / unlocking device in which locking / unlocking operation is performed using a lock (key) is generally used, but in the case of collectively managing locking / unlocking of a large number of cabinets in an office or the like. Is
If the locking / unlocking device is a manual type as described above, it takes time and effort to lock / unlock each cabinet. Therefore, there is an electric locking / unlocking device that can be locked / unlocked by a locking / unlocking operation from a distance.

[0004]

However, when the latter electric locking / unlocking device is used to lock / unlock the drawer by a locking / unlocking operation from a distance, for example, the drawer can be unlocked by another user. If the drawer is pulled out, or if the drawer is not completely closed for some reason, the person using the drawer will not be able to close the drawer or the locking / unlocking device will be unlocked. It is conceivable that the locking / unlocking device will malfunction due to an excessive load.

Therefore, it is conceivable to provide detection means or the like for detecting the open / closed state of each drawer, but if a plurality of detection means are provided for each drawer, not only is it troublesome to assemble the detection means, There was a risk that the cost would increase.

The present invention has been made by paying attention to such a problem. Locking and unlocking is performed according to the open / closed state of the drawer, and a plurality of detecting means for detecting the open / closed state of the plurality of drawers are provided. The purpose is to provide a drawer-type cabinet that can be confirmed without the need for confirmation.

[0007]

In order to solve the above-mentioned problems, a drawer type cabinet of the present invention has a plurality of drawers provided in a vertical direction in a multi-tiered manner in a cabinet body and at a predetermined position of a side plate of the cabinet. A moving member provided so as to be movable up and down, and provided between the moving member and the drawer to move the moving member up and down in coordination with the opening / closing operation of one of the drawers, and also to move the moving member up and down. A drawer type cabinet that prevents simultaneous opening of a plurality of drawers by means of an engagement / disengagement means capable of restricting the opening of the drawers by means of which the moving member can be moved up and down in order to lock / unlock all drawers simultaneously. Locking / unlocking part linked to the moving member, position detecting means capable of detecting the vertical position of the moving member, and a locking signal or unlocking signal transmitted from a transmitter. In case of receiving the items, it is characterized in that it comprises a control unit for performing the drive control of the locking and unlocking unit in accordance with the detection result by the position detection means. According to this feature, the control unit controls the locking / unlocking by the locking / unlocking unit based on the open / closed state of the drawer when the locking signal or the unlocking signal is received. Since it is possible to prevent unlocking in the locked state or locking in the locked state, the user who is using the drawer at that time can not close the drawer, or the lock and unlock part is overloaded. Will not break down. Further, since the open / closed state of the drawer can be recognized without providing a detecting means for detecting the open / closed state of the drawer for each drawer, the labor and cost at the time of manufacturing can be effectively reduced.

In the drawer type cabinet of the present invention, it is preferable that the position detecting means is a non-contact sensor that can detect a detected portion provided at a predetermined position of the moving member in a non-contact manner. With this configuration, even if the moving member frequently moves up and down in conjunction with the opening / closing operation of the drawer, the position detecting means is not deteriorated due to friction or the like, and thus maintainability is improved.

In the drawer type cabinet of the present invention, a unit member integrally assembled with the respective element parts for driving the locking / unlocking part is reinforced on the side plate of the cabinet so as to face vertically. It is preferably fixed to the column. With this configuration, each element portion is fixed to the strong reinforcing column, so that rattling or dropping of the unit member can be reliably prevented.

In the drawer-type cabinet of the present invention, the control section and the electricity supply section for supplying electricity to the drive section for driving the locking / unlocking section are divided into left and right sides in the longitudinal direction of the reinforcing column. It is preferable to provide. By doing so, both can be provided in a well-balanced manner.

In the drawer type cabinet of the present invention, when the control section receives the locking signal from the transmitter, it is determined that any of the drawers is in an open state based on the detection result of the position detecting means. In this case, it is preferable to control so that the locking / unlocking unit does not lock. By doing so, the drawer is not locked in the opened state, so that it is possible to prevent the user of the drawer from being unable to close the drawer or to prevent the locking / unlocking part from being unduly loaded by the locking. .

In the drawer-type cabinet of the present invention, the control unit externally indicates that the locking / unlocking unit has not performed the locking / unlocking signal even though the locking / unlocking signal is received from the transmitter. It is preferable that an informing means for informing is connected. In this way, it is possible to prevent the drawer from being left open, which improves the manageability.
