DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for a sliding cabinet, and more particularly, to a movable cabinet disposed in front of a fixed cabinet to secure a passage formed between the movable cabinets. Related to safety devices.

[0002]

2. Description of the Related Art Conventionally, a plurality of fixed cabinets are arranged side by side with an access surface facing the front, and a plurality of movable cabinets are provided on a front deck in front of the fixed cabinets so as to be slidable in the horizontal direction. There are various types of slide cabinets in which a passage is formed between movable cabinets so as to make the entrance / exit surface appear.

[0003] In these sliding cabinets, a plurality of movable cabinets are slid horizontally in front of the cabinets to form a passage between the movable cabinets so as to open an entrance surface of a specific fixed cabinet, and a passage is formed between the movable cabinets. When a user enters and moves goods into and out of the intended fixed cabinet, if another person moves the movable cabinet without knowing that he is in the aisle and moving in and out, the previous move between the movable cabinets is made. There is a risk that the user will be pinched. Also, when not in use,
When a lateral force is applied to the movable cabinet, the movable cabinet suddenly moves, and when the force is generated by a person leaning on the movable cabinet, the person may fall down.

Therefore, it is considered to provide some type of stopper mechanism so that the movable cabinet does not move carelessly during use. For example, there is no fixed cabinet behind a movable cabinet that slides forward in the horizontal direction, and it is not a cabinet used from the front side. However, Japanese Utility Model Publication No. 3-12274 discloses a storage box body that can be moved along a rail. Attach the pedal to the lower part of the front, and move the pin that is connected to the pedal and moved up and down between the position where the lower end is inserted into the lock hole provided on the rail and the lower end moves upward from the lock hole when the pedal is moved up and down. A device is described which is mounted in the lower part of the storage box and the pin is elastically biased downward. That is, when a predetermined space is secured between the storage boxes, the pins are engaged with the lock holes by the elastic urging force to restrict the movement of the storage box. However, it is not possible to move a plurality of storage boxes at the same time, since it is necessary to depress the pedals of all the storage boxes and pull out the pins from the lock holes. It takes time and effort to move the body.

[0005] Incidentally, a structure in which a buffer member protrudes from the side surface of a movable cabinet so that the buffer member abuts on the side surface of another movable cabinet facing when an adjacent movable cabinet approaches is already known. Although provided, it does not restrict the movement of the movable cabinet with the passage formed by the buffer member.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned situation, the present invention is intended to solve the problem by arranging a plurality of fixed cabinets side by side with the access surface facing the front, and on the front deck in front of the fixed cabinets. A plurality of movable cabinets are provided so as to be slidable in the horizontal direction, and a passage is formed between the movable cabinets so that an entrance / exit surface of an arbitrary fixed cabinet can appear. In the formed passage,
In the middle passage, restrict the movable cabinet from moving from both sides or from one side in the side passage, so that people entering the passage and using it suddenly can move to the moving cabinet. Another object of the present invention is to provide a safety device for a slide cabinet in which a passage is safely secured so as not to be pinched or collided and the operation thereof is easy.

[0007]

Therefore, in order to solve the above-mentioned problems, the present invention has a plurality of fixed cabinets arranged side by side with the access surface facing the front, and a plurality of fixed cabinets arranged on a front deck in front of the fixed cabinets. The movable cabinet is provided so as to be slidable in the horizontal direction, and a passage is formed between the movable cabinets so that an entrance / exit surface of an arbitrary fixed cabinet can be made to appear, and a side surface of each movable cabinet faces the movable cabinet. A cushioning member that abuts on a side surface of another movable cabinet is rotatably mounted, and the cushioning member has a short-diameter portion whose distance from the rotation axis is shorter than the distance between the rotation axis and the upper surface of the front deck, and a longer portion. A safety device for a sliding cabinet having a long diameter portion was constructed.

[0008] In order to maintain a state in which the short diameter portion and the long diameter portion of the cushioning member are located immediately below the axis of rotation, an engaging means is provided between the cushioning member and a side surface of the movable cabinet. It is preferable that the buffer member has a star shape in which a substantially triangular projection is projected radially from a circular main body in a side view. It is also preferable that a buffer member is provided at a front portion of one side surface of the movable cabinet and a buffer member is provided at a rear portion of the other side surface.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. FIG. 1 shows an example of a sliding cabinet according to the present invention, in which 1 is a fixed cabinet, 2 is a movable cabinet, 3 is a front deck, 4 is a passage, and 5 is a safety device.

[0010] The slide type cabinet according to the present invention comprises:
A plurality of fixed cabinets 1, with the access surface 6 facing the front.
Are arranged in the horizontal direction, a plurality of movable cabinets 2,... Are slidably movable in the horizontal direction on the front deck 3 in front of the movable cabinets 2,. This is a structure having a passage 4 formed therebetween. As shown in FIGS. 2 and 3, the movable cabinet 2 has a vertical rotating shaft projecting from a top track 7A provided on a front edge of a top plate 7 of the fixed cabinet 1 at an upper end portion on a rear surface of the movable cabinet 2. The rolling bearing 7B having the above-mentioned structure is provided so as to be able to roll and restrict forward movement, and the rail 8 formed on the front deck 3 is formed.
.. Provided on the base 9 are slidable by rolling. The top truck 7A is fixed to each fixed cabinet 1 and communicates with each other. Alternatively, one long object having a length extending over a plurality of fixed cabinets 1,. May be.

The fixed cabinet 1 is of a unit type, and is connected side by side to form a large storage cabinet. The movable cabinet 2 is a unit type similarly to the fixed cabinet 1, and their widths are set to be substantially the same. Usually, the number of the movable cabinets 2 is set to be smaller than the number of the fixed cabinets 1 by one, and the passage 4 having a width corresponding to the width of one fixed cabinet 1 is formed. Also, the front deck 3 is a unit type corresponding to the fixed cabinet 1, and the same number of front decks 3 as the number of the fixed cabinets 1 are arranged in front of the fixed cabinets 1,. The illustration shows three fixed cabinets 1,
This is a case where there are two movable cabinets 2. The fixed cabinet 1 is preferably of a shelf type with an open / close surface 6 being open, but a horizontal sliding door may be provided, and the movable cabinet 2 is preferably of a shelf type with an opening door at the front or a drawer type. However, the storage structure is not particularly limited.

As shown in FIGS. 3 and 4, the front deck 3 is provided with ground members 11, which are laid at regular intervals in a horizontal direction in a direction perpendicular to the entrance / exit surface 6 of the fixed cabinet 1.
Assemble and form on top. The front deck 3 is divided into front and rear parts, and is provided with a space between the front front deck 3A and the rear front deck 3B and connected by the connecting member 12, and is fixed to the connecting member 12 within the space. The rail 8 is provided.

As shown in FIGS. 1 to 8, the safety device 5 of the present invention is provided on the side surface 13 of each movable cabinet 2, more specifically, on the side surface 13 of the base 9, with another movable cabinet facing the same. Shock-absorbing member 1 which abuts on side 13 of 2
4 is rotatably mounted, and the cushioning member 14 has a short-diameter portion (distance S) and a long-diameter portion whose distance from the rotation axis O is shorter than the distance D between the rotation axis O and the upper surface 15 of the front deck 3. (Distance L). Here, as shown in FIG. 5, the cushioning member 14 has a star shape in which five substantially triangular projections 14B project radially from a circular main body 14A in a side view. here,
The distance L of the long diameter portion is defined by the distance between the rotation axis O and the protrusion 14B.
The distance S of the minor diameter portion corresponds to the length of a perpendicular drawn from the rotation axis O to a straight line connecting the edges of the adjacent projections 14B, 14B.

More specifically, the cushioning member 14 is made of synthetic rubber or soft synthetic resin so that the protrusion 14B is elastically pressed against the upper surface 15 of the front deck 3 to increase the sliding friction resistance. However, softness such that deformation is extremely easy is inconvenient for restricting movement of the movable cabinet 2. Also, a through hole 16 is formed at the center of the main body portion 14A of the cushioning member 14,
A concave portion 17 is formed around the through hole 16 on the outer surface side, and is inserted by a reinforcing plate 18 disposed on the inner surface side of the main body portion 14A and a flat washer 19 disposed in the concave portion 17. In this state, a rotating shaft 20 composed of a bolt with a head penetrating through the central hole 19A of the flat washer 19, the through hole 16 and the central hole 18A of the reinforcing plate 18 is fixed to the side surface 13 of the base 9.

In order to fix the rotating shaft 20 to the side surface 13 of the base 9, the screw shaft 2 that is stepped down at the tip of the rotating shaft 20 is used.
0A, the screw shaft 20A is inserted into a mounting hole 21 formed in the side surface 13, and a nut 23 screwed to the screw shaft 20A via a flat washer 22 and an end of a shaft portion 20B of the rotating shaft 20. Then, the side surface 13 is tightened and fixed. Although the cushioning member 14 can rotate around the shaft portion 20B of the rotating shaft 20, there is a risk that the stopper member 14 may unexpectedly rotate from the stopper operation state to the release state if rotated freely. An engagement means is provided between the cushioning member 14 and the side surface 13 of the movable cabinet 2 so as to maintain a state in which the short diameter portion and the long diameter portion of the member 14 are located immediately below the rotation axis O.

The engaging means includes the reinforcing plate 18
On the circumference centered on the center hole 18A, ten burring holes 24,... Recessed into the inside of the cushioning member 14 are formed at regular intervals, and the long-diameter portion, that is, the projection 14B is formed.
Or at least one dowel 25 or a slider or plunger that engages with at least one burring hole 24 when the short diameter portion, that is, the intermediate portion between the adjacent protrusions 14B, 14B is located immediately below the rotation axis O. It protrudes from the side surface 13 of the movable cabinet 2 around the mounting hole 21. Setting the head 20C of the rotating shaft 20 so as not to protrude from the concave portion 17 of the cushioning member 14 is such that when the two movable cabinets 2 and 2 adjacent to each other are approached, the cushioning member 14 faces the cushioning member 14. It is indispensable to stop against the side surface 13 of the movable cabinet 2 on the other side to perform a buffering action.

Next, the operation of the safety device 5 of the present invention will be described with reference to FIG. First, when the stopper is released as shown in FIG.
Since the length S of the perpendicular drawn down to the straight line connecting the ends of B and 14B is short, the buffer member 14 does not contact the upper surface 15 of the front deck 3, so that the movable cabinet 2 can be moved freely. In the stopper operation state of FIG. 5B, the cushioning member 14 is rotated by stepping on the protrusion 14B facing obliquely upward from the state of FIG. Burring hole 2
If the position of the dowel 25 with respect to 4, ... is shifted by one,
Since the distance L from the rotation axis O to the tip of the projection 14B is longer than the distance D, one of the projections 14B is pressed against the upper surface 15 of the front deck 3 while being deformed, and is located immediately below the rotation axis O. As a result, the movable cabinet 2 can be stably stopped at an arbitrary position by frictional resistance with the protrusion 14B of the buffer member 14 pressed against the upper surface 15 of the front deck 3. The position where the movable cabinet 2 is stopped is usually a state where the passage 4 is formed, but can be stopped at any other position.

The position where the cushioning member 14 as the safety device 5 of the present invention is provided is a diagonal position between the front part on one side of the movable cabinet 2 and the rear part on the other side as shown in FIG. .

In another embodiment of the safety device 5 of the present invention shown in FIG. 9, a through hole 16 is formed at a position eccentric from a center of a circular cushioning member 14 in a side view. It is rotatably mounted on the side surface 13 of the movable cabinet 2. And it has a short diameter portion 26 and a long diameter portion 27 centered on the rotation shaft 20. When the major diameter portion 27 is pressed against the upper surface 15 of the front deck 3 as shown in FIG. Other configurations are the same as above.

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

[0021]

According to the safety device for a sliding cabinet of the present invention as described above, the movable cabinet is moved to use a specific fixed cabinet, a passage is formed in front of the movable cabinet, and then the movable cabinet enters the passage. When the buffer member of the movable cabinet facing the corresponding passage is rotated and its long diameter portion is pressed against the upper surface of the front deck, it is necessary to reliably restrict the movable cabinet from moving into the passage once formed. That would allow people in the aisle to enter the aisle and be suddenly caught in the moving cabinet,
Alternatively, the passage can be secured safely without collision, and the operation is easy since the operation is merely kicking and rotating the cushioning member with the foot.
