Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a fixture in which a large number of containers with open tops for storing articles such as medical equipment and drugs are housed in a drawer shape in the height direction of a cabinet. .

Prior art and its problems Conventionally, there is a well-known fixture in which containers with an open top for storing articles such as medical equipment and drugs are housed in a drawer shape in the height direction in a cabinet with an open front and back sides. The container is put in and taken out by pulling the container forward or by pulling the container out of the cabinet.

By the way, according to the conventional configuration, a locking protrusion is provided on the lower side of the container, and a guide rail is provided inside the opposite side of the cabinet to slidably receive the lower side of the container in the height direction. The guide rail is arranged in a stepped manner, and at the end position of the guide rail is a locking portion that comes into contact with the locking protrusion to prevent the container from falling out of the cabinet when the container is pulled out horizontally. If the container is to be pulled out, the locking protrusion is disengaged from the locking portion by slightly lifting the container.

However, conventional fixtures configured in this way,
A locking protrusion is provided on the bottom of the container, so if you pull the container out of the cabinet and place it on a tabletop, the locking protrusion may scratch the tabletop surface or cause it to get caught on other objects. In addition, since the bottom surface of the container is placed on a guide rail, the storage condition in the cabinet is unstable, and the container cannot be stored in the height direction. The drawback was that it also took up a lot of space.

OBJECTS, EMBODIMENTS AND EFFECTS OF THE INVENTION Therefore, the present invention provides for a container to be inserted into and taken out from a pair of guide rails fixed to a cabinet by means of a seesaw rod provided at an end position of the guide rails when the container is pulled out and stored. , which improves the defects of the conventional one by locking, and one embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is a cabinet with open front and rear surfaces, and guide rails 2,
2,... are horizontally fixed at required intervals in the height direction, and on the rails 2, 2... of each stage,
A container 3, which has a rectangular planar shape with an open top surface and has an integrally formed flange 3a bent into a key-shaped cross section along the periphery of the opening, can be taken in and out through the left and right flange portions 3a ₁ and 3a ₂ . It is supported by and housed in the cabinet 1.

_The guide rails 2, 2 _{, .}
As is clear from FIG. 3 (only one guide support part is shown), the guide support parts 2a, 2a have an inwardly U-shaped cross section for slidingly guiding the guide support parts 2a, 2a. Frame part 2 with a U-shaped cross section in the opposite direction to 2a
b, 2b are integrally formed, and this frame portion 2b, 2b
A seesaw rod 4 having upward locking portions 4a, 4b protruding from below at the front and rear ends thereof is vertically rotatably built into the guide support portions 2a, 2a at the front and rear positions.

The intermediate portion of the seesaw rod 4 is supported within the frame portions 2b, 2b, and the front locking portion 4a seen from the opening side is located at the guide support portions 2a, 2a.
It emerges and retracts from a through hole 5 that is located at the end in the length direction and is located on the surface where the lower edges of both side flanges 3a ₁ and 3a ₂ of the container 3 slide into contact, and from the opening surface side. The rear locking portion 4b as seen is the both side flanges 3a ₁ and 3a ₂ of the container 3.
The lower edge emerges and retracts from a through hole 6 that is located inward from the sliding surface.

A shaft part 4c provided in the middle part of this seesaw rod 4
In this case, the front locking part 4a is always connected to the guide support part 2a,
The frames 2b, 2b of the seesaw rod 4 are fitted and supported in the bearing recesses 7 formed in the frames 2b, 2b in a rotationally biased state so as to protrude into the seesaw rod 2a.
The installation is carried out from the outer open surface of the guide support portions 2a, 2a.Therefore, the guide support portions 2a, 2a have a cutout groove 8 extending from the outer surface to the lower surface, which is continuous with the through hole 6 through which the rear locking portion 4b is inserted and retracted. It is formed.

Note that the front end of the locking portion 4a of the seesaw rod 4 is inclined outward, and the guide rail 2,
Cutting parts 9, 9 are formed on the upper surfaces of the front and rear ends of the guide support parts 2a, 2a constituting the guide support part 2. 1 in the diagram
1 is a caster, 12 is a handle, and 13 is a shelf.

Next, the operation of the fixture configured as described above will be explained.

When the container 3 is stored and held between the guide rails 2, 2 of the cabinet 1, each of the front locking portions 4 of the front and rear seesaw rods 4, 4, as shown in FIG.
a, 4a protrude into the guide support parts 2a, 2a of the guide rails 2, 2, respectively, and connect the front and rear flanges 3 of the container 3.
a ₃ , 3 a ₄ are in contact with the outer surfaces of the container 3 , so that the container 3 is held in an immovable state locked in the front and back direction with respect to the guide rails 2 , 2 , and is protected against external vibrations or slopes acting on the cabinet 1 when the cabinet 1 moves. When moving on a floor surface with rough edges, there is no risk of it moving on its own and slipping out due to turbulence.

In this state, if you want to move the cabinet 1 to a desired position and pull out the container 3, lift the drawer side (the front side in this example) of the container ₃ a little and pull it out _{a little} . The lower edge of is placed on the front locking portion 4a of the seesaw rod 4 in the near side position. Then, the front locking part 4a is pushed down by the load of the container 3, the seesaw rod rotates around the shaft support, and the rear locking part 4b connects through the through hole 6 to the guide support of the guide rails 2, 2. 2a, protrudes into 2a.

Next, when the container 3 is pulled out from this state and pulled out approximately two-thirds of the way, the inner surface of the rear flange _3a4 is aligned with the guide support portion 2a, as shown in FIG. 5B.
The seesaw rod 4 protrudes into the rear locking portion 4b of the seesaw rod 2a and is locked, preventing the container 3 from being pulled out from the guide rails 2, 2. The container 3 is held in a pulled-out state, and articles stored in the container 3 can be taken in and out in a stable manner. Also, after putting in and taking out stored items,
When pushed and slid against the guide rails 2, 2, the front locking portion 4a of the seesaw rod 4 in the rear position
By being in a protruding state, the outer surface of the rear flange _3a4 of the container 3 is brought into contact with and received.

On the other hand, the front locking part 4a of the seesaw rod 4 in the front position
are detached from the lower edges of both side flanges 3a ₁ and 3a ₂ of the container 3 and protrude into the guide support portions 2a and 2a, so that the outer surface side of the front flanges 3a ₃ of the container 3 comes into contact with this. It turns out.

In this way, the container 3 is again locked in the front-back direction by the front locking portions 4a, 4a of the seesaw rods 4, 4 at the front and back positions with respect to the guide rails 2, 2, and is housed and held in the cabinet 1. .

Note that the above example shows the case where the seesaw rods 4, 4 are provided at the front and rear positions of the guide rail so that the front and rear surfaces of the cabinet 1 can be opened and the container 3 can be pulled out from the front and rear directions. In the case of a configuration in which only the cabinet 3 is opened and the container 3 is pulled out from the front side, the rear flange _3a4 of the container 3 will be received by the rear panel of the cabinet 1, and the seesaw located on the rear side will be received by the back panel of the cabinet 1. The rod is omitted.

In addition, when removing _the container 3 from the cabinet 1, lift the container _{3 slightly} from the state shown in FIG. Move further away. Then, the rear locking portion 4b of the seesaw rod 4 retracts, allowing the container 3 to be pulled out sufficiently toward the front, and then the rear flange portion _3a2 of the container 3 and the front locking portion 4 of the seesaw rod 4
The container 3 can be extracted from the cabinet 1 by lifting the container 3 and releasing the contact with the container 1a.

In addition, in the above-described drawing operation of the container 3, when the container 3 is lifted on the drawer side and placed on the front locking part 4a of the seesaw rod 4, the container 3 is tilted with respect to the guide rails 2, 2.
Since the cutout parts 9, 9 are formed on the upper surfaces of the ends of the guide support parts 2a, 2a of the guide rails 2, 2, the container 3 can be easily tilted, and the drawing operation can be performed smoothly. .

Effects of the Invention As described above, according to the present application, when the container is pulled out, the container is lifted slightly and the lower edge of the side flange is placed on the front locking portion of the seesaw rod, and then the container is simply pulled out. The length allows the container to be pulled in the forward direction, allowing the container to be pulled out from the front of the cabinet easily and reliably.In addition, when the container is stored in the cabinet, the container is received by the front locking part of the seesaw rod. Therefore, when moving the cabinet due to the vibrations that act on the cabinet or when moving on a sloped floor, etc., the container can be safely handled without worrying about the container being pulled out forward due to disturbance, and can be handled safely when moving on a floor surface with a slope. Since it is provided at the position of the guide path and does not appear on the front of the cabinet, it has the advantage of good appearance and convenient operation of pulling out the container using both hands.
