Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a fixture in which a large number of open-top containers for storing articles such as medical equipment and drugs are housed in a cabinet in a vertical direction. .

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 cabinet with an open front and back sides in a plurality of vertically extending containers. The container can be put in and taken out by pulling the container out toward the front or by pulling the container out of the cabinet.When putting in and taking out items with the container pulled out, it is possible to prevent the container from falling out of the cabinet unnecessarily. It was necessary to hold the cabinet in a horizontal position, and it was also necessary to be able to easily remove it from the cabinet when pulling it out to take items in and out.

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 released from the locking portion by slightly lifting the container.

However, conventional fixtures configured in this way,
A locking protrusion protrudes from 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 damage 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 stability of the storage condition relative to the cabinet is poor, and the container is difficult to store in the height direction. The drawback was that it also took up a lot of space.

Purpose, Examples and Effects of the Invention Therefore, the present invention does not require a locking protrusion to protrude from the bottom surface of a container to be stored in a cabinet, but instead has a flange provided along the top opening at a predetermined position in the pull-out direction. In addition to forming a downward notch recess, a locking protrusion is provided on the guide rail of the cabinet.
By locking the notch recess with this locking protrusion, the defects of the conventional device have been improved.An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a cabinet with open front and rear surfaces, and guide rails 2, 2 each having a U-shaped cross section are opposed to each other on both left and right side surfaces, and are horizontally fixed at required intervals in the height direction. At the front and rear ends of the inner surfaces 2a, 2a of the lower pieces of 2, 2, locking protrusions 3, 3 with inclined front end surfaces are provided in a protruding manner. Reference numeral 4 denotes a rectangular container in plan view with an open top to be housed in the cabinet 1. A flange 4a bent into a key-shaped cross section is integrally formed along the periphery of the opening. Downward, preferably trapezoidal notched recesses 5, 5 are formed at the left and right positions so as to face each other at their central positions. , is stored by inserting it into a pair of opposing guide rails 2, 2, and in this state, the flange 4 of the container 4
The front and rear vertical planes of a are located between the front and rear locking protrusions 3, 3 of the guide rails 2, 2.

Therefore, in order to slide the container 4 forward from this state, for example, lift the container 4 slightly and pull it out toward you so that the left and right vertical lower edges of the flange 4a are opposed to the left and right locking protrusions 3, 3. Slide in this state. Then, the inclined rear end edges of the notched recesses 5, 5 are engaged with the locking protrusions 3, 3 of the guide rails 2, 2, and the container 4 is prevented from being pulled out any further. It protrudes about two-thirds from the front of the cabinet 1, and articles can be taken in and taken out in this state.

Furthermore, when the container 4 is slightly lifted from the state in which the notched recesses 5, 5 are locked with the locking protrusions 3, 3 and further pulled out toward the front, the locking protrusions 3, 3 and the notch recesses 5, 5 are engaged with each other. The stop is released and the container 4 can be taken out from the cabinet 1.

In the figure, 6 is a caster, 7 is a handle, 8 is a shelf, and 9 is a stop rod that is rotatably provided on the cabinet 1 and extends in the height direction. The container 4 is prevented from flying out and the container 4 is rotated outward when the container 4 is pulled out.

By the way, since this type of container is generally made by synthetic resin molding, the container 4 is
When the container 4 is being used with the container 4 pulled out about two-thirds forward, the left and right edges of the top opening of the container 4 may move inward due to the load of the items stored in the container 4. There is a risk that the left and right vertical portions of the collar portion 4 may fall off from the locking protrusions 3, 3.

Therefore, the present application further provides locking protrusions 3, 3 provided at the ends of the lower inner surfaces 2a, 2a of the guide rails 2, 2.
The device is characterized in that it is provided with raised portions 3a, 3a that come into contact with the vertical inner surface of the flange portion 4a of the container 4.

Therefore, even if the container 4 is deformed by the load of the stored articles while being pulled out from the cabinet 1, the vertical lower edge of the flange 4a will come into contact with the raised parts 3a, and the container will not be able to enter the container any further. Since it does not move in the direction, the flange 4a from the guide rails 2, 2
However, it can be used safely without fear of falling off.

In this example, cutouts 6, 6 are provided at both ends of the upper pieces 2b, 2b of the guide rails 2, 2 so that the containers 4 can be easily pulled out and inserted into the cabinet 1. . That is, when removing the container 4, the container 4 is lifted at the front position with the rear end edges of the notch recesses 5, 5 of the collar 4a being locked with the locking protrusions 3, 3 of the guide rails 2, 2. When the container 4 is tilted greatly, the locking state described above can be easily released.
When inserting the flange 4a into the guide rails 2, 2
By inserting it diagonally from above, the lower edge of the tip will be at a position beyond the locking protrusions 3, 3.
It can be easily placed on the lower pieces 2a, 2a of the guide rails 2, 2.

Effects of the Invention As described above, according to the present application, a flange bent into a key-shaped cross section is integrally provided along the upper opening of the container, and the flange is slidably placed on the guide rail. A downward notch recess is formed at a predetermined position in the vertical part of the container, and a locking protrusion is provided at the end of the surface of the guide rail in the pull-out direction on which the flange is placed. It does not have any protrusions on the underside, so the container does not have any protrusions from the cabinet.
Even if the container is pulled out and placed on a table board, for example, there is no risk of damaging the table board, and the container can be easily pulled out, and the guide rail is placed within the height direction of the container. Therefore, the storage space for the unit containers in the cabinet is reduced.Furthermore, according to the present application, since the locking protrusion is provided with a ridge portion that comes into contact with the vertical inner surface of the flange of the container, it is difficult to pull out the container from the cabinet. There is no risk of the collar part coming off the guide rail during handling of stored articles, etc., and safe handling is possible.
