Various slide-type cabinets are provided in which work spaces are formed between movable cabinets.

  These sliding cabinets are used in the work space by forming a work space between the movable cabinets by sliding a plurality of movable cabinets laterally in front of them to open the entrance and exit surfaces of any fixed cabinet. The person enters and puts in and out the target fixed cabinet, but if another person moves the movable cabinet without knowing that it is in the work space, the movable cabinet is moved between the movable cabinets. There is a risk that the previous user may be caught.

  Therefore, it has been proposed to provide some kind of stopper mechanism so that the movable cabinet does not move carelessly during use.

  In Patent Document 1 as an example, a plurality of fixed cabinets are arranged in a horizontal direction with the entrance / exit surface facing the front, and a plurality of movable cabinets are provided on the front deck in front of the movable cabinet so as to be slidable in a horizontal direction. In a slide-type cabinet in which a work space is formed between movable cabinets so that the entrance / exit surface of the fixed cabinet appears, the shaft is rotatably arranged along the front front edge of the front deck corresponding to the entrance / exit surface of each fixed cabinet Then, a pedal projecting forward in the middle portion of the shaft is projected from the opening on the front surface of the front deck, and when the pedal is stepped on and the shaft rotates, the pedal projects from the top surface of the flot deck to the working space side of the movable cabinet. A configuration in which stoppers are provided at both ends or one end of the shaft so as to restrict movement is disclosed. .

JP-A-10-146225 (see FIGS. 1 to 6)

  However, in the configuration of Patent Document 1, since the pedal for operating the stopper protrudes from the opening on the front surface of the front deck, a foot of a passerby who passes near the front surface of the front deck collides with the pedal and falls. There was a fear.

  Further, in the configuration of Patent Document 1, it is necessary to hold the stopper in the protruding state by stepping on the pedal before entering between the movable cabinets. If the user forgets the operation or cannot hold the protruding state, the user The accident of being caught between movable cabinets cannot be avoided.

  The present invention has been made in view of the above-mentioned drawbacks of the prior art, and a normal state is a state in which the movable cabinet is prevented from moving, and a slide that allows the movable cabinet to move when the user performs a release operation. The object of the present invention is to provide a safety device for a mold cabinet.

  In order to solve the aforementioned problems, the slide cabinet safety device of the present invention has a plurality of fixed cabinets arranged in a horizontal direction with the entrance and exit surfaces facing the front, and a plurality of movable cabinets on the front deck. A slide-type cabinet provided so as to be slidable in a lateral direction parallel to the entrance / exit surface, and configured to be able to form a work space in which each entrance / exit surface of an arbitrary fixed cabinet appears by movement of an arbitrary movable cabinet, 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 an area where the lower surface of the movable cabinet moves, and the stopper body is normally in a protruding state. , The stopper body can come into contact with the moving direction end surface of the movable cabinet, and the operator presses the stopper body, When the stopper member is submerged is to the upper of the stopper member is movable cabinet is configured to be passed through.

  According to a second aspect of the present invention, in the slide cabinet safety device according to the first aspect, the front deck is provided with elastic biasing means for biasing the stopper body in the protruding direction. It is what.

  According to a third aspect of the present invention, in the safety device for a slide type cabinet according to the first or second aspect, the stopper body extends along a moving direction of the movable cabinet, and a dimension in the extending direction is the arbitrary value. It is characterized by being formed shorter than the horizontal dimension of each entrance / exit surface of the fixed cabinet.

  According to a fourth aspect of the present invention, in the safety device for a slide type cabinet according to the first aspect, the stopper body has an abutting surface on an end surface in the moving direction of the movable cabinet with respect to the upper surface of the front deck. The stopper body is provided so as to be pivotable via a horizontal axis so that it can be projected and retracted, and the stopper body applies a rotational moment due to a weight of a portion opposite to the contact surface side across the horizontal axis. It is formed so as to be larger than the rotational moment due to the weight of the portion on the surface side.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows an example of a slide-type cabinet according to the present invention, in which 1 denotes a fixed cabinet, 2 denotes a movable cabinet, 3 denotes a front deck, 4 denotes a work space, and 5 denotes a safety device.

  In the slide type cabinet according to the present invention, a plurality of fixed cabinets 1 are arranged in a horizontal direction with the entrance / exit surface 6 facing the front, and a plurality of movable cabinets 2 are slid in a horizontal direction on the front deck 3 in front of the fixed cabinets This is possible. The front deck 3 is provided with one rail 7 extending along the row of fixed cabinets 1, and a trochanter 10 provided on the base 9 of the movable cabinet 2 rolls on the rail 7. A horizontal guide trochanter 11 attached to a bracket projecting rearward from the upper end of each movable cabinet 2 is fixed to the front face of the upper end of the fixed cabinet, and extends downward along the row of the fixed cabinet 1. Mates inside. As a result, each movable cabinet 2 can be slidably moved by a guiding means that restricts at least the back-and-forth movement and guides it horizontally with respect to the front surface of the fixed cabinet 1 (see FIGS. 1 and 2).

  The fixed cabinet 1 is a unit type, and it is connected to the sides one after another to form a large storage cabinet. Moreover, the movable cabinet 2 is a unit type similarly to the fixed cabinet 1, and those horizontal widths are set to be substantially the same. Normally, the movable cabinet 2 is set to a number smaller by one than the number of the fixed cabinets 1 so that the space between the two movable cabinets 2 has a width corresponding to the width of the single fixed cabinet 1. A work space 4 is formed. Further, the front deck 3 is also a unit type corresponding to the fixed cabinet 1, and the same number of front decks 3 as the number of fixed cabinets 1 are arranged in front of the fixed cabinet 1. The front deck 3 is arranged so that one end or both ends in the longitudinal direction approach each other at right angles to the chamber wall, so that the wall surface, the side surface of the movable cabinet 3 facing the wall, and the entrance and exit of the fixed cabinet 1 Since the space surrounded by the three sides between the surface 6 may be the work space 4, the work space 4 described below includes these.

  The illustrated case is a case where there are four fixed cabinets 1 and three movable cabinets 2. In addition, although the fixed cabinet 1 is preferably a shelf type and the entrance / exit surface 6 is open, a horizontal sliding door may be provided, and the movable cabinet 2 is preferably a shelf type and provided with a front door on the front or a drawer type. However, the storage structure is not particularly limited.

  As shown in FIGS. 3 and 5, the front deck 3 is formed by assembling on a grounding member 13 laid at a constant interval in the lateral direction in a direction orthogonal to the entrance / exit surface 6 of the fixed cabinet 1. The front deck 3 is divided into front and rear, and is connected by a connecting member 14 with a space between the front front deck 3A and the rear front deck 3B, and is fixed to the connecting member 14 within the space. Rail 7 is arranged.

  The safety device 5 of the present invention can be moved in and out on the side of the front deck 3 where the lower surface of the movable cabinet 2 moves, on the side closer to the entrance / exit surface 6 of the fixed cabinet 1 (the side close to the entrance / exit surface 6). The stopper body 20 (30) is normally provided, the stopper body 20 (30) is in a protruding state, and the stopper body 20 (30) can be brought into contact with the end surface of the movable cabinet 2 in the moving direction. When the body 20 (30) is pressed down and the stopper body 20 (30) is submerged, the movable cabinet 2 is configured to pass above the stopper body 20 (30). The reason why the stopper body 20 (30) is provided on the side close to the entrance / exit surface 6 of the fixed cabinet 1 (the side close to the entrance / exit surface 6) is that when the worker enters and exits the work space 4 from the front of the front deck 3. In addition, this is to prevent the operator's feet from crawling on the stopper body 20 (30) or inadvertently pressing the stopper body 20 (30) with the workers' feet.

  As shown in FIGS. 1 to 7, the stopper body 20 of the first embodiment of the safety device 5 extends along the moving direction of the movable cabinet 2, and the dimension L <b> 2 in the extending direction is each of the fixed cabinets 1. The entrance / exit surface 6 is formed shorter than the lateral dimension L1.

  In the embodiment, the stopper body 20 is formed of a synthetic resin material such as POM, but may be other materials such as metal. It is preferable that the buffer body 21 made of a rubber material or the like is fixed to both ends in the longitudinal direction of the stopper body 20 with screws 22 or the like. This is because when the movable cabinet 2 collides with the end of the stopper body 20, both members are not damaged or damaged.

  The front deck 3 is provided with elastic biasing means including a spring or the like for biasing the stopper body 20 in the protruding direction. In the embodiment, as shown in FIG. 5, the stopper body 20 is disposed between the adjacent ground members 13 so as to be movable up and down with respect to the lower case 23 that is open and connected in parallel with the connecting member 14. ing. Then, as shown in FIG. 7, a mounting is provided between a mounting portion 24 (with a boss that is fitted and positioned on the inner diameter portion of the coil spring) that is recessed in the lower surface of the stopper body 20 and the bottom plate 23 b of the lower case 23. The stopper body 20 is elastically urged upward by the compression coil spring 25 thus formed.

  On the other hand, in order to move the stopper body 20 up and down substantially horizontally, a pair of side plates 23a of the lower case 23 are provided with vertical guide grooves 26 at a plurality of locations, and on the other hand, corresponding to the longitudinal side surface of the stopper body 20. A number of guide pins 27 are penetrated and fixed sideways. When each guide pin 27 is moved up and down while being inserted into each guide groove 26, the stopper body 20 can move up and down in a substantially horizontal shape.

  With the above configuration, for example, as shown in FIG. 1, when the work space 4 is formed between the adjacent movable cabinets 2, the stopper body 20 is biased upward by the compression coil spring 25, and the stopper body 20. Most of the height portion protrudes from the upper surface of the front deck 3. In this state, an end surface in the moving direction (referring to a front end surface or a rear end surface orthogonal to the moving direction) of the base 9 or the like of the movable cabinet 2 can come into contact with the buffer body 21 or the like of the protruding stopper body 20 (FIG. 6 FIG. 7). Therefore, the working space 4 is further prevented from being narrowed by the movable cabinet 2.

  When moving the movable cabinet 2, the operator presses a part of the upper surface of the stopper body 20. Then, the stopper body 20 sinks substantially horizontally and substantially flush with the upper surface of the front deck 3. In this state, the movable cabinet 2 is moved so as to pass above the submerged stopper body 20. When a part of the stopper body 20 in the longitudinal direction is covered with a part of the lower surface of the base 9 in the movable cabinet 2, the upper surface of the stopper body 20 comes into sliding contact with the long lower surface plate 9a along the moving direction of the base 9, Since the upward protrusion of the stopper body 20 is prevented, the movable cabinet 2 is allowed to move. As described above, unless the operator depresses the stopper body 20, the stopper body 20 protrudes on the upper surface of the front deck 3 in a normal state to prevent the movable cabinet 2 from moving and the work space 4 is narrowed. Since it can prevent, the operator in the working space 4 is not pinched by the movable cabinet 2. FIG.

  When a part of the stopper body 20 in the longitudinal direction is covered with a part of the lower surface of the base 9 in the movable cabinet 2, the operator may lift the foot from the stopper body 20. If a thin protrusion 20a extending along the longitudinal direction is formed on the upper surface of the stopper body 20, sliding frictional resistance and sliding noise with the lower surface plate 9a of the base 9 can be extremely reduced, and comfortably. The movable cabinet 2 can be moved.

  The stopper body 20 is disposed for each portion (work space 4) where the entrance / exit surface 6 of each fixed cabinet 1 is opened. That is, as shown in FIG. 1, when the safety device 5 (stopper body 20) is provided on the intermediate front deck 3, the movable cabinets 2, 2 on both sides approach each other, and an operator in the work space 4 is caught. Can be prevented. On the other hand, by providing a safety device 5 (stopper body 20) on the front deck 3 located at the side end (see FIGS. 5 and 6), a wall surface (not shown) located at the end of the front deck 3 is provided. Therefore, it is possible to prevent the one movable cabinet 2 from approaching and to ensure the safety of the operator.

  The stopper body 30 of the second embodiment of the safety device 5 shown in FIGS. 8 to 10 has a contact surface 30a with respect to the end surface in the moving direction of the movable cabinet 2 that can protrude and retract with respect to the upper surface of the front deck 3. It is provided so as to be rotatable via a horizontal shaft 31 so that The stopper body 30 is formed such that the rotational moment due to the weight of the portion on the opposite side of the contact surface 30a across the horizontal shaft 31 is greater than the rotational moment due to the weight of the portion on the contact surface 30a side. ing. More specifically, by making a through hole 32 on the inner diameter side of the portion 33 on the contact surface 30a side (see FIG. 10), the weight of the portion on the contact surface 30a side is reduced. As another embodiment, after the stopper body 30 is formed of a synthetic resin material such as POM or a metal material, a member having a higher specific gravity may be embedded in the opposite portion. Since the stopper body 30 of the second embodiment is a rotary type, it is suitable for downsizing.

  Even in this stopper body 30, the stopper body 20 has a portion 33 on the abutting surface 30 a side of the front deck 3 in a normal state unless the operator depresses the portion 33 on the abutting surface 30 a side of the stopper body 30. It protrudes to the upper surface and can prevent the movement of the movable cabinet 2 (see the states of FIGS. 8, 9 and 10). As a result, the work space 4 can be prevented from being narrowed, so that an operator in the work space 4 is not caught by the movable cabinet 2.

  When the operator depresses the portion 33 on the abutting surface 30a side of the stopper body 30, the stopper body 30 becomes horizontal at the position where the portion 33 is substantially low, as in the two-dot chain line state of FIG. To rotate so as to sink from the upper surface of the front deck 3. In this state, when at least a part of the portion 33 on the contact surface 30 a side of the stopper body 30 is covered with a part of the lower surface of the base 9 in the movable cabinet 2, the upper surface of the portion 33 is moved in the moving direction of the base 9. Along with the long bottom plate 9a, the upward protrusion of the stopper body 30 is prevented, so that the movable cabinet 2 is allowed to move. Thus, when a part of the portion 33 of the stopper body 30 is covered with a part of the lower surface of the base 9 in the movable cabinet 2, the operator may lift the foot from the stopper body 30.

  In the second embodiment, as shown in FIG. 8, in the intermediate work space 4, a pair of stopper bodies 30 are provided on the front deck 3 with their contact surfaces 30a opposite to each other and separated from each other as appropriate. It is possible to prevent the movable cabinets 2 and 2 on both sides from approaching and an operator in the work space 4 from being caught. On the other hand, in order to prevent one movable cabinet 2 from approaching the wall surface (not shown) located at the end portion of the front deck 3 located at the side end portion, on the side away from the wall surface (not shown). By providing the stopper body 30 at the end of the front deck 3 (see FIGS. 8 and 9), the safety of the operator can be ensured.

  The safety device 5 of the present invention is not limited to the above-described manual slide type cabinet but can be similarly applied to an electric moving shelf device.
