DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention comprises a box-shaped frame structure having a ceiling frame,
The present invention relates to a storage rack that can be stacked in a plurality of stages in the vertical direction and that can be lowered by sequentially nesting from above when not in use.

2. Description of the Related Art Conventional storage shelves as described above include, for example,
The structures disclosed in No. 6816 are provided. As shown in FIG. 7 and FIG.
A, 22A and 21B, 22B is connected between the supported members 23A, 23B of which the lower surface is open between the lower ends, and the supported members 23A, 23B of the upper storage rack are fitted between the upper ends when stacking. The support members 24A and 24B having a mountain-shaped cross-section that can be combined are connected to each other, and the intervals between the rear columns 22A and 22B are formed so as to be able to pass between the front columns 21A and 21B, and the upper portions of the columns 21A, 21B, 22A, and 22B. A ceiling frame 25 for loading is connected between them.

[Problems to be Solved by the Invention] According to the above-described conventional configuration, when stacking during use, as shown in FIG. 8, the supported members 23A, 23B and the supporting member 2 are supported.
4A, 24B, that is, the chevron and chevron are stacked and supported. Therefore, in the mountain-shaped cross section of the supported members 23A, 23B, the strength, particularly the bending strength, is insufficient for the load of the load, and the strength is reduced when the spread-out load acts, and the stack becomes unstable. was there. Further, the flanges 26A, 26B, 27A, 27B for attaching the supported members 23A, 23B to the lower ends of the columns 21A, 21B, 22A, 22B are the supported members 23A, 23B.
The joint surface with and had to be cut into a mountain shape, and it took time and labor to process and weld it. Furthermore, the supported member 23
Since the reinforcing members 28A, 28B arranged above A, 23B receive the corners (tops) of these supported members 23A, 23B,
Fixing such as welding cannot be performed easily, and sufficient reinforcement effect cannot be expected.

An object of the present invention is to provide a storage shelf which is provided with a supporting member and a supported member which have sufficient strength, are easy to process, and are sufficiently reinforced.

Means for Solving the Problems In order to achieve the above-mentioned object, a storage shelf of the present invention comprises a pair of left and right front vertical columns and a pair of left and right rear vertical columns in which a rear vertical direction is larger than an inner surface interval of the front vertical columns. The pillars are arranged so that the outer surface distance between them is small, and the upper portions of these pillars are connected by a ceiling frame whose width fits within the inner surface distance. A supported member having an open U-shaped cross section and a reinforcing member that abuts on the flat upper surface of the supported member are provided, and the upper and lower storage shelves of the upper storage rack are stacked between the upper ends of the vertical columns facing each other in the front and rear. A support plate having a mountain-shaped cross section into which the supported member can be fitted is provided so that the corner portion is the top, and the rear end portion of the supporting member restricts the rearward movement of the upper supported member. And the width of the supporting member is made larger than the opening width of the supported member. It was done.

Action When stacking storage shelves vertically, lift the upper storage shelves at the front of the lower storage shelves a little higher than the upper ends of the vertical columns of the lower storage shelves using a forklift or the like. Then, the position is adjusted in the left-right direction, and the rear end portion of the upper supported member is positioned so that the front end portion of the lower supporting member can be fitted, and the upper storage rack is moved rearward. By this movement, the rear end of the upper supported member comes into contact with the lower regulating plate, and then it is lowered to fit the supported member of the upper storage rack into the supporting member of the lower storage rack. In this way, the upper storage shelves can be supported on the lower storage shelves to facilitate stacking. Further, since the supported member has a U-shaped cross section and a large strength is obtained, and further, since the supporting member has a flat upper surface, it can be easily fixed to the reinforcing member and sufficient reinforcement can be expected.
At the rear of the lower storage shelf that is landing, lift the upper storage shelf to be nested so that it is slightly higher than the upper end of the control plate of the lower storage shelf, and then between the front vertical columns of the upper storage shelf. Through, push the upper storage shelf so that the rear vertical columns and ceiling frame of the lower storage shelf and the supporting member are fitted, lower the upper ceiling frame so as to face the lower supporting member, and lower the upper storage shelf. Nesting can be performed by landing the ceiling frame on the support members 8A and 8B of the lower storage shelf.

Embodiment An embodiment of the present invention will be described below with reference to FIGS.

1A and 1B are a pair of left and right front vertical columns, 2A and 2B are a pair of left and right rear vertical columns, and these are the outer surface spacing l _{1 of the} rear vertical columns 2A and 2B more than the inner surface spacing L of the front vertical columns 1A and 1B.
Are arranged at the four corners of the quadrangle so as to be small. The width l between the upper portions of the columns 1A, 1B, 2A, 2B is
₃ are connected by a lattice-shaped ceiling frame (container) 3 that fits within the inner surface distance L.

And the vertical columns 1A, 2A and 2 facing each other in the front and rear
Between the lower ends of A and 2B, supported members 4A and 4B having a U-shaped cross-section whose lower surface is open are arranged. The supported members 4A and 4B have longitudinal columns 1A and 1B at their front and rear ends. , 2
A reinforcing member 7 attached to the reinforcing plates 5A, 5B, 6A, 6B fixed to A, 2B and provided between the reinforcing plates 5A and 6A facing each other in the front-rear direction and between 5B and 6B.
The flat lower surface of A, 7B is brought into contact with the flat upper surface,
The lower end surface is set to be flush with the lower surfaces of the vertical columns 1A, 1B, 2A, 2B. In addition, this reinforcing member 7
The lower surfaces of A and 7B are formed of, for example, square cylinders having a flat shape, and are joined to the upper surfaces of the supported members 4A and 4B.
The bottom ends of the rear vertical columns 2A and 2B are connected by a cross member 9. Further, on the ceiling frame 3 so as to be located between the upper ends of the vertical columns 1A, 2A and 1B, 2B facing each other in the front-rear direction, when the storage shelves are vertically stacked, the upper supported members 4A, The support members 8A and 8B having a mountain-shaped cross section into which 4B can be fitted are arranged so that their corners are the top sides. The width a of the supporting members 8A and 8B is the same as that of the supported member 4
When the storage shelves are set to be larger than the opening width b of A and 4B, both side leg portions 4a of the supported members 4A and 4B are supported by being in contact with the inclined surfaces 8a of the support members 8A and 8B, and the upper storage is performed. Even when the shelves are placed so as to be shifted left and right, the upper storage shelves are centered by the action of the inclined surface 8a.

Further, on the rear end surfaces of the support members 8A, 8B, the regulation plates 11A, 11 for regulating the rearward movement of the upper storage shelves at the time of storage.
B is installed. Here, the inner surface distance l ₂ between the support members 8A and 8B is set to be larger than the outer surface distance l ₁ between the rear vertical columns 2A and 2B. Therefore, this storage rack is a box-shaped frame body whose front and bottom surfaces are open, and can be inserted from the front surface of the lower storage rack with the upper storage rack slightly lifted during nesting. At the time of this nesting, abutting members 12A, 12B which can come into contact with the supporting members 8A, 8B of the lower storage shelf from above are attached to the lower surface of the ceiling frame 3. 1
Reference numerals 0A and 10B denote connecting members.

A square pipe body is used as the frame component member of the above embodiment.

Next, the operation will be described.

The storage shelves are installed at a desired place at the time of use, but in this case, as shown by phantom lines in FIGS. 2 and 4, the storage shelves can be stacked vertically in a plurality of stages to effectively use the space. That is, in the case of stacking in two upper and lower tiers, the upper storage rack is lifted slightly higher than the upper ends of the lower vertical columns 1A, 1B, 2A, 2B by a forklift at the front of the landed lower storage rack and moved in the left-right direction. Then, the front parts of the lower support members 8A and 8B and the rear parts of the upper support members 4A and 4B are positioned so that they can be fitted to each other, and the upper storage rack is pushed rearward to regulate the upper support members 4A and 4B. Board 11A, 11
Lower it at the position where it abuts B, and support member 8 for the lower storage shelf.
The supported members 4A and 4B of the upper storage shelf are fitted and supported on A and 8B. At this time, as shown in FIG. 6, the lower supporting members 8A and 8B are formed in a mountain-shaped cross section, and
The cross-sections of the upper supported members 4A, 4B are formed in a U-shape with a bottom opening, and the width a of the supporting members 4A, 4B is
Is smaller than the opening width b of the supported members 8A and 8B,
The lower ends of both legs 4a of the support members 4A, 4B are the support members 8A,
8B is contacted with the inclined surface 8a and centered. The storage of the load in this state can be performed by taking the load in and out of the storage shelf at the lowermost stage by using the inner surface distance L and placing it on the floor. Further, the load put in the upper storage rack can be supported by being supported by the ceiling frame 3 of the storage rack immediately below.

When the above-mentioned storage rack is not used for storing a load, nesting can be performed low. That is, in the rear part of the lower storage shelf that is landing, the upper storage shelf to be nested is attached to the restriction members 11A and 11B of the lower storage shelf by the contact members 12A and 12B.
Lift so that it is a little higher than the top edge of. Then, the upper storage shelf is pushed through the front vertical columns 1A and 1B of the upper storage shelf so that the rear vertical columns 2A and 2B of the lower storage shelf and the ceiling frame 3 and the support members 8A and 8B are fitted to the lower storage shelf to support the lower stage. The upper contact members 12A and 12B are made to oppose above the members 8A and 8B and descend. Then, the contact members 12A, 12B of the upper storage shelf can be landed on the support members 8A, 8B of the lower storage shelf, and nesting can be performed as shown by phantom lines in FIG.

As described above, according to the present invention, when stacking the storage shelves up and down at the intended place, at the front of the lower storage shelves,
Raise the upper storage shelf a little higher than the upper end of the lower vertical column to position the upper supported member so that it can be fitted to the lower supporting member, and then position the upper storage shelf where the supported member is the lower regulating plate. By pushing and lowering until it comes into contact with the upper support member, the lower support member can be fitted and supported by the upper support member.

In such stacking, since the supported members are formed in a U-shaped cross section, a larger bending strength can be obtained as compared with the conventional chevron, and moreover, when the supporting members are fitted together, the legs facing up (side plates) face upward. Since the load is along the surface of the leg,
Greater strength is obtained. Further, when the supported member is connected to the vertical column, the connection with the connecting member and the reinforcing member may be performed on the flat surface portion, and the working and welding can be easily performed as compared with the inclined surface of the conventional chevron. At the same time, because of the surface connection, the reinforcing effect of the reinforcing member can be expected sufficiently. Furthermore, nesting can be performed easily and stably.
