Description

  The present invention relates to a safety lock device for a mobile cabinet, and more particularly to a safety lock device for restricting movement of a mobile cabinet in order to ensure the safety of a work space.

  Conventionally, multiple fixed cabinets are arranged in the horizontal direction with the entrance and exit surfaces facing the front, and a plurality of movable cabinets are slidably moved on the front deck in front of them. Various slide-type cabinets are provided in which work spaces are formed between movable cabinets in order to appear. Normally, the front movable cabinet can be used directly at any position, but when using the rear fixed cabinet, it is necessary to move the movable cabinet located in front of it to form a work space. is there. Workers enter and leave the work space in this work space, but without knowing that the work is in progress, if another worker moves the movable cabinet, or if the movable cabinet moves due to rolling due to an earthquake, This causes a problem that the worker is caught between the movable cabinets or collides with the movable cabinet. Therefore, it has been proposed to provide some kind of stopper mechanism so that the movable cabinet does not move unexpectedly.

  In Patent Document 1, a shaft is rotatably disposed along an inner front edge of a front deck corresponding to an entrance / exit surface of each fixed cabinet, and a pedal projecting forward at an intermediate portion of the shaft is provided on the front surface of the front deck. The stopper is provided at both ends or one end of the shaft so that the movement of the movable cabinet to the working space side is restricted when the pedal is stepped on and the shaft rotates. A safety device for a slide-type cabinet is disclosed.

  In Patent Document 2, the front deck is provided with a stopper body that can be moved in and out on the side closer to the entrance / exit surface of the fixed cabinet in the area where the lower surface of the movable cabinet moves. Is in a projecting state by the elastic biasing means, the stopper body can be brought into contact with the moving direction end surface of the movable cabinet, and when the operator presses the stopper body and the stopper body is submerged, A slide cabinet safety device is disclosed in which a movable cabinet is configured to pass above the stopper body.

  However, the safety device of Patent Document 1 increases the rotational moment due to the weight of the stopper extending backward than the pedal extending forward, and maintains the state in which the stopper is pulled into the front deck in a normal state. The opening formed so that the pedal protrudes and can be moved up and down in front of the front deck is an upper opening taper in which the upper opening width is set wider than the lateral width dimension of the pedal and the lower opening width is set smaller than the lateral width dimension of the pedal. Since the structure is such that the pedal protrudes from the front deck when the pedal is depressed, the pedal formed in a substantially U shape in plan view and the lower part of the opening are maintained by elastic force and frictional force. If an impact force acts on the shaft or stopper due to an earthquake or movement of a movable cabinet, the lock may be released. Moreover, since the pedal protrudes in front of the front deck, it cannot be denied that it obstructs forward traffic. On the other hand, the safety device of Patent Document 2 protrudes from the front deck by an elastic biasing force so that the stopper body is always locked, and the stopper body is automatically pushed in when the movable cabinet passes through the stopper body from one side. Since the stopper body is designed to come into sliding contact with the bottom surface of the base and the other end of the base from the other side, when the movable cabinet is moved in that direction, the stopper in front of the moving direction is used. The body must be pushed down with the foot, and the operation is complicated when searching for a fixed cabinet for moving the movable cabinet to the left and right to put in and out the target article.

  FIG. 14 shows another embodiment of the lock portion 15, and the operation portion 14 can be locked by depressing the operation button 18 at a position shifted from the engagement portion 46 of the stopper plate 23. After that, the movable cabinet 2 is slightly moved back and forth, and when the positions of the stopper body 17 and the engaging portion 46 coincide with each other, the stopper body 17 automatically engages with the engaging portion 46 and becomes locked. is there. The lock portion 15 of the present embodiment has the same basic structure as that described above. However, the block body 47 is made to face the base end side of the stopper body 17 inside the lock body 29 and the stopper body 17. A compression coil spring 48 having a slightly larger elastic force than the compression coil spring 35 is interposed between the block body 47 and the base end of the stopper body 17 so as to be movable in the same direction as the block body 47. The back surface is pressed by the operating piece 42 of the operating member 39 inserted through the slit opening 30. In the locking operation, when the back surface of the block body 47 is pressed by the operating piece 42, the stopper body 17 is moved in a protruding direction via the compression coil spring 48, and the tip of the stopper body 17 is moved to the stop plate 23. When the contact is made, the compression coil spring 48 is pressed and contracted, and the operation portion 14 is locked, and the state can be maintained. Then, when the movable cabinet 2 moves and the stopper body 17 comes to the position of the engaging portion 46, it is pushed out by the elastic force of the compression coil spring 48 and engaged with the engaging portion 46. This mechanism is effective in the case where the movement of the movable cabinet 2 is suddenly stopped when the movable cabinet 2 suddenly starts moving while working in the work space S without forgetting to set the lock state.

  Alternatively, although not shown, the stopper body 17 is composed of two members on the proximal end side and the distal end side with respect to the lock portion 15 having the structure shown in FIGS. The structure is such that the side member is slidably moved parallel to the protruding and retracting direction of the stopper body 17 and elastically biased by a compression coil spring or the like in the direction in which the distal end side member protrudes from the proximal end side member. Emergency stop is possible.
