[0012]

An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 6 and 7, reference numeral 1 denotes a pair of front and rear fixed shelves, and a plurality of movable shelves 2 movable in the front and rear direction are arranged between the fixed shelves 1. Each of the movable shelves 2 includes a lower frame 3 and a shelf 4 installed on the upper portion of the lower frame 3. Also, a plurality of rails 5 are laid on the floor, and each moving shelf 2 is
Are supported and guided by these rails 5 via a plurality of wheels 6a and 6b provided in the vehicle.

As shown in FIG. 5, the lower frame 3
Are lower frame members 8 located at both left and right ends, and lower intermediate frame members 9 located between the lower frame members 8 on both sides;
The connecting member 10 connected between the side lower frame member 8 and the intermediate lower frame member 9 forms a frame.

As shown in FIG. 2, the lower side frame member 8 and the intermediate lower frame member 9 are each composed of a pair of left and right side plates 11 and an upper plate 12 connected between upper ends of the both side plates 11.
Thus, it is formed in a gate shape with an open bottom surface. Further, the wheels 6a, 6b are distributed and attached to the front and rear of each of the frame members 8, 9 via an axle 13 inserted between both side plates 11. As shown in FIG. 5, one of the wheels 6a of the intermediate lower frame material 9 is provided on the intermediate lower frame material 9.
Is mounted. This motor
The wheel 14a and the wheel 6a are linked and connected via a sprocket and a chain. Further, one wheel 6a of the intermediate lower frame member 9 and one wheel 6a of the side lower frame member 8 are linked to each other by a drive shaft 15.

As shown in FIGS. 1 to 4, end cover plates 18 are attached to the front and rear ends of the side lower frame member 8 and the intermediate lower frame member 9, respectively, to cover both ends of the frame members 8, 9. Have been. These end cover plates 18
Has bent pieces 19 whose both ends are bent rearward, and is formed in a channel shape in plan view. The lower portions of these bent pieces 19 are notched. These end cover plates 18 are fitted to the front and rear ends of each of the frame members 8 and 9 and connected and fixed by blind rivets 20.

On the back side of the end cover plate 18, a groove type frame 21 having one side surface and open upper and lower surfaces is mounted. These grooved frames 21 are mounted with one open side facing the back surface of the end cover plate 18, and are connected and fixed by a blind rivet 22 and a blind nut 23. As a result, the grooved frame 21 is located between the front and rear ends of the side lower frame material 8 and the intermediate lower frame material 9 and between the side plates 11, respectively, and the end cover plate 18 and the grooved frame
A rectangular insertion hole 24 surrounded by 21 is formed at both front and rear ends of each of the frame members 8 and 9. The upper and lower ends of the upper plate 12 of the frame members 8 and 9 are provided with upper and lower holes 24.
Is formed by cutting out a penetrating portion 25 that communicates with.
These penetrating portions 25 are squares having the same shape and the same size as the insertion hole 24, and are located above the insertion hole 24.
A support bolt 26 is inserted through the insertion hole 24 in the width direction and fixed to a lower portion of the groove type frame 21 with a nut 27.

As shown in FIGS. 6 and 7, the shelf 4 is
A plurality of storage sections 31 are provided in the vertical and horizontal directions by a pair of front and rear vertical pillars 28 and 29 and a shelf board 30 mounted between the vertical pillars 28 and 29 across the width direction. A plurality of the vertical supports 28 and 29 are provided at regular intervals in the width direction, and a square pipe material is used as the vertical supports 28 and 29. Figure 1
As shown in FIGS. 2 and 4, the lower portions of the vertical columns 28, 29 can be inserted into the insertion holes 24 from above through the through portions 25, respectively.

Further, as shown in FIG.
Is formed by a lower frame body 34 mounted and fixed on the floor and a shelf 35 mounted on the lower frame body 34. A plurality of storage sections 36 are formed in the shelf 35 in the vertical and horizontal directions.

The operation of the above configuration will be described below.
When assembling the movable shelf 2, the shelf unit 4 is installed on the lower frame body 3 as follows. That is, the shelf 4 is placed on the lower frame body 3, and at this time, the vertical columns 28 and 29
Is inserted into the insertion hole 24 through the through portion 25 from above the lower frame body 3. And each vertical support 28, 29
By being inserted into the insertion hole 24 until its lower end surface comes into contact with the support bolt 26, it is accurately inserted by a predetermined depth. Thereby, the shelf part 4 has the vertical struts 28 and 29
It is inserted into and fixed to 24 and supported by support bolts 26, and is accurately and easily installed on the lower frame body 3 without tilting in the front-rear direction and the left-right direction. Also,
Since the lower parts of the vertical columns 28 and 29 are inserted into the insertion holes 24,
The installation strength is excellent, and the labor for adding a special insertion portion to the shelf 4 can be omitted.

When assembling the lower frame 3,
The grooved frame 21 is attached to the end cover plate 18 via the blind rivet 22 and the blind nut 23, and then these end cover plates 18 are attached via the blind rivet 20 to the lower side frame member 8 and the intermediate lower frame member 9. Attach to both front and rear ends. Thereby, the insertion hole 24 can be easily formed in the lower frame body 3. Also, as shown in FIG. 3, by preparing unit parts 37 in which the grooved frame 21 is attached to the end cover plate 18 in advance for each size, the lower frame body 3 of various sizes can be more quickly. Therefore, the assembling time of the lower frame body 3 can be reduced.

Each of the movable shelves 2 assembled in this way is placed on a rail 5 and, if necessary,
It is supported and guided by and moves in the front-back direction. For example, when loading / unloading cargo to / from the moving shelf 2 shown in FIG.
Each of the movable shelves 2 is moved to form a work space 38 such as a forklift in front of the target movable shelf 2 in (a). Similarly, when loading / unloading cargo to / from the fixed shelf 1,
What is necessary is just to move each moving shelf 2 to form a work space in front of the target fixed shelf 1.

In normal use, the vertical support columns 28 and 29 do not inadvertently fall out of the insertion holes 24 because the weight of the shelf unit 4 always acts downward. In the above embodiment, the insertion hole 24 is formed in the lower frame body 3 of the movable shelf 2, and the lower portions of the vertical supports 28 and 29 of the shelf 4 of the movable shelf 2 are
The fixed shelf 1 has a structure in which the insertion hole 24 is formed in the lower frame body 34 of the fixed shelf 1.
The lower portions of the 35 vertical columns 28 and 29 may be inserted into the insertion holes 24.

[0023]

As described above, according to the first aspect of the present invention, the shelf is placed on the lower frame body, and the lower part of the vertical support is inserted into the insertion hole at this time, so that the shelf is connected to the lower frame body. Since the shelf is supported and fixed, the shelf can be easily installed on the lower frame body.

Further , by inserting the groove type frames into the end cover plates and then attaching these end cover plates to both ends of the frame material, insertion holes can be easily formed in the lower frame body. In addition, by preparing in advance for each size a unit component having a grooved frame attached to an end cover plate, it is possible to more quickly respond to a lower frame body of various sizes. It is possible to save time. In addition, the insertion hole above
Cylindrical shape surrounded by groove type frame and end cover plate
The lower part of the vertical support at a predetermined depth (high
Can be inserted into the insertion hole over
The lower part of the pillar is from the surroundings with a grooved frame and end cover plate
Supported, which allows the lower part of the
The joining strength is improved.

According to the second aspect of the present invention, by inserting the vertical support into the insertion hole until the lower end surface of the vertical support comes into contact with the support bolt, the vertical support can be inserted exactly to a predetermined depth, and therefore the shelf can be inserted. Can be accurately installed on the lower frame body.
