When the guide piece 4 and the levitating stopper 5 are attached to the inside of the frame body 1 as described above, the reinforcing member extending obliquely between the end of the supporting piece 3 and the end of the guiding strip 4 or the levitating stopper 5 is provided. Is desirably provided to prevent bending of the guide piece.

The container 2 is a rectangular shallow box. Container 2
May be made of metal, but is preferably made of hard synthetic resin. FIG. 4 shows one integrally formed of a hard synthetic resin. A flange 21 slightly protruding outward is formed on the upper edge of the container 2. The side wall 22 is slightly inclined toward the bottom, and the inclination angle α is 8 to 15 degrees. As the hard synthetic resin, it is preferable to use ABS resin, polyolefin, particularly polypropylene, polycarbonate, polyamide and the like.

At the place where the support piece 3, the guide piece 4 and the floating stopper 5 are fixed to the metal pipe 11 constituting the frame,
When the container 2 is inserted, the container 2 can be stored in a stable state as shown in FIG. That is, when the container 2 is placed on the support piece 3 and pressed, the container 2 only comes into contact with the center of the support piece 3. Particularly, when a round bar is used as the metal bar, the container 2 , And can be moved on the support piece 3 without any hindrance, so that the container 2 can be easily taken in and out. In particular,
When the container 2 is made of a synthetic resin, the container 2 can be put in and out more easily without producing any sound.

At this time, since the outer surface of the side wall of the container 2 is guided by the guide piece 4, the container 2 can be easily stored at a predetermined position. When the container 2 thus stored is taken out,
Even if an unexpected force is applied, it can be easily pulled out by being guided by the guide piece 4 and sliding on the support piece 3 without being greatly inclined due to the presence of the levitating stopper 5. Thus, the container shelf of the present invention can easily put the container 2 in and out of the predetermined position in the frame.

In the present invention, the support piece 3, the guide piece 4 and the floating stopper 5 are all made of metal rods.
Since it can be easily bent without crushing the cross-sectional shape, and it is enough to bend it in a U-shape in the longitudinal direction,

It can be easily and reliably fixed by inserting until it collides with the opposite surface and welding around the hole in this state.

The container shelf according to the present invention forms a rectangular parallelepiped frame simply by fixing four equal-sized metal pipes to the four corners of a rectangular quadrilateral, so that its manufacture is easy. Yes, and the frame is solid. Further, as described above, since the support piece 3, the guide piece 4, and the floating stopper 5 can be easily and firmly fixed to the metal pipe 11, the manufacture of the container shelf is easy.

Further, since the four sides of the manufactured container shelf are all open, the container can be put in and out in any direction when manufacturing the container shelf. That is, when producing the container shelf, the side from which the container is taken out can be arbitrarily determined depending on which side of the frame is to be provided with a component such as a support piece. This makes it possible to provide a variety of container shelves by reducing the types of frames and containers, which is a great advantage for a container shelf manufacturer.

In the state described above only, the side surface of the container shelf is left open, and there is a possibility that the stored container may jump out of the frame body in any way. In order to prevent this, an escape prevention tool 6 is additionally provided in FIG. The escape preventing device 6 is arranged on a side surface from which the container 2 can be pulled out, extends over the upper and lower sides of the containers 2 arranged in a hierarchy, and can be fixed to the side surface. It can be easily removed from.

For this reason, the escape preventing device 6 is shown in FIG.
The structure is as shown in FIG. That is, the escape preventing tool 6 has a rectangular frame composed of two elongated bodies 61 and 62 extending vertically and two arms 63 and 64 extending horizontally, and the arms 63 and 64 are connected to the metal pipe 11. Extend to
A ring 65 is attached to the end of the ring, and the ring 65 is circumscribed to the metal pipe 11. Thus, the escape preventing device 6 can be rotated around the metal pipe 11 as an axis.

The escape preventing device 6 is fixed as follows to fix it to the side surface of the frame 1. That is, the ring 65 attached to the upper arm 63 of the escape preventing device 6 is

According to the present invention, a rectangular parallelepiped frame formed by fixing four equal-sized metal pipes at four corners of a rectangular quadrilateral is used as an outer shell, and a supporting piece is attached to the outer frame. Since the shallow box-shaped container is placed on the container shelf and the supporting piece is made of a metal rod, it can be easily bent in a U-shape in the longitudinal direction unlike a metal pipe. They have high strength and are easy to weld to metal pipes. Further, the support piece is formed into a U-shape, and the center portion of the U-shape is fixed to a metal pipe in a state where the center portion of the U-shape extends parallel to the side surface of the frame and horizontally, and such a support piece is used. Since the metal pipes are provided facing each other over a plurality of steps at equal heights, the containers can be placed on the facing support pieces, and the plurality of containers can be arranged vertically. At this time, since the bottom of the container only comes into contact with the upper surface of the central portion in the supporting piece, the contact surface is small, so that the container can be easily taken in and out.

Further, since the four side surfaces of the frame body are open, the container can be taken in and out from the two opposite side surfaces, which is convenient. Furthermore, since the four side surfaces are open, the direction in which the container is put in and taken out can be changed by changing the attaching direction of the support piece as described above. This makes it possible to produce a container shelf in a different direction, which is advantageous for the production of the container shelf.

When a guide piece is provided above each support piece, the guide piece is formed by bending a metal rod into a U-shape, and both ends are fixed to a metal pipe or a support piece. Since the central portion is outside the central portion of the support piece in the frame and extends parallel to the central portion of the support piece, the guide piece guides the outer surface of the side wall of the container to an appropriate position when inserting the container, and In place, thus making it easier to put the container in and out.

Further, by providing a floating stopper above each guide piece, even if an unexpected force is applied to the container stored in the frame, the container is maintained in a normal state, and the container is inserted and removed. And easy to be with. In addition, since the floating stopper is simply formed by bending a metal bar into a U-shape, the suspension is easy to manufacture and can be easily fixed to the frame.

It is assumed that it is sufficient to provide an escape-preventing device on the side of the frame body, from which the container is inserted or taken out, and to make the escape-preventing device a long body rotatable around a metal pipe. Therefore, it is easy to manufacture. In addition, since the escape prevention device can be engaged with the engagement piece attached to the frame simply by releasing the escape prevention device, the container can be prevented from easily coming off the container shelf.

Further, by attaching a caster to the lower end of the metal pipe, this container shelf can be used as a cart while storing articles, which is more convenient.

The present invention provides such benefits.
