Description

[Detailed description of the invention] [Industrial field of application] The present invention provides a mobile shelf in which shelf boards are attached via pillars with an L-shaped cross section arranged at the four corners, and wheels are attached to the four corners of the lower end. This invention relates to an improvement of the wheel mounting device.

[Prior Art] In general, to attach wheels to fixtures such as cabinets, a mounting plate is fixed to the bottom of the fixture, and wheels are mounted to the bottom of the mounting plate, as disclosed in Japanese Utility Model Publication No. 57-27604. As described,
Conventionally, when installing wheels on a shelf made by attaching a shelf plate through a column with an L-shaped cross section, the lower part of the column is extended below the joint with the lowest shelf plate, and the lower end surface is Place the base plate horizontally and secure it by welding.
The wheels are fixed to the base plate.

However, when wheels are attached to a shelf with the above-mentioned structure on a shelf where shelves are attached via pillars with an L-shaped cross section, there is no connection relationship between the base plate to which the wheels are attached and the lowest shelf. Since there is no structure and the wheels are supported only by the cross section of the pillars, the wheels swing due to the torsional deformation of the pillars and cannot support large loads.
In addition, when installing the wheels on the lower surface of the base plate, in order to prevent the base plate from being bent and deformed,
The wheels should be installed so that the part that touches the floor is located directly below the column, but if this is done, a portion of the wheels and wheel support brackets will protrude from the outer surface of the column, making it difficult to move the shelf. There was also a risk that objects could be damaged by touching other objects, or people's feet could be injured by touching them.

In addition, with this conventional wheel mounting device, the shelf is assembled and the base plate is fixed by welding or the like, which increases the number of steps required to assemble the entire mobile shelf, making assembly time-consuming. There was also a problem.

The object of the present invention is to solve the problem of attaching wheels to a shelf constructed of columns having an L-shaped cross section.

[Means for solving problems]

In order to solve this purpose, the present invention connects the top shelf board and the bottom shelf board at the four corners of both shelves with pillars having an L-shaped cross section, and also connects the top shelf board and the bottom shelf board by pillars having an L-shaped cross section. is a movable shelf provided with wheels, and at the lower four corners of the shelf, there are base plates each having a rectangular shape in plan view, each side having a length larger than the width of the side plate of the pillar, and an adjacent base plate of the base plate. A connecting member consisting of a side plate projecting upward on two sides is provided, and the inner surface of the both side plates of the connecting member is placed on the outside of the corner of the lowermost shelf board, and the inner surface of the column is placed on the outside of the corner of the lowermost shelf board. The pillars, the side plates of the connecting member, and the bottom shelf board are integrally fastened together with bolts, while the wheels are attached to the lower surface of the base plate of the connecting member. This is a configuration with a .

〔Example〕

Next, an embodiment of the present invention will be described based on the drawings. In the drawings, reference numeral 1 indicates that the uppermost shelf 2 and the lowermost shelf board 3 are connected at their four corners by pillars 4 having an L-shaped cross section. A shelf is shown in which an intermediate shelf board 5 is mounted between the upper shelf board 2 and the lowest shelf board 3, and wheels 7 such as casters are mounted at the lower four corners of the shelf 1 via connecting members 6. It is installed.

As clearly shown in FIG. 6, the coupling member 6 includes a base plate 8 having a rectangular shape in plan view, and
The base plate 8 is composed of upwardly facing side plates 9 and 10 integrally connected to two adjacent side pieces of the base plate 8.
Bolt insertion holes 1 for fastening wheel support brackets 12 are provided in the left and right side plates 9 and 10, respectively.
1 and a bolt insertion hole 14 for fixing the coupling member 6 to the lowermost shelf board 3. The length of one side of the base plate 8 in the connecting member 6 is appropriately larger than the width of the mutually orthogonal side plates of the column 5 (therefore, the width of the side plates 9 and 10 is also the same as that of the side plate of the column 4). larger than the width).

Then, the wheel support bracket 12 is fastened with bolts 13 to the lower surface of the base plate 8 of the coupling member 6, while
The inner surfaces of the left and right side plates 9, 10 of the coupling member 6 are brought into close contact with the outer surfaces of the corners of the lowermost shelf board 3, and the inner surfaces of the pillars 4 are brought into close contact with the outer surfaces of the connected corners of the left and right side plates 9, 10 from the outside. Side plates 9 and 1 of the pillar 4 and the connecting member 6
0 and the lowest shelf board 3 using multiple bolts 1.
It is concluded integrally at step 6.

In this case, since the left and right widths of the side plates 9 and 10 of the coupling member 6 are larger than the width of the vertical side plates of the column 5, the side plates 9 and 10 of the coupling member 6 are connected to the column 4 and the lowermost shelf board 3. It plays the role of a gazette board to reinforce the base board 8 and also connects the base board 8 to the pillar 4 and the lowest shelf board 3, so the connection between the wheels 7 and the shelf 1 is strong, and deformation near the four corners is prevented. This means that a large load can be supported by the wheels 7 without causing any damage.

Furthermore, since the horizontal widths of the side plates 9 and 10 of the coupling member 6 are larger than the horizontal widths of the side plates of the column 4, the area where the base plate 8 cannot be flexibly deformed becomes larger than the bottom surface area of the column 4. Connect the grounding point of 7 to pillar 4.
Therefore, even when large wheels are attached, the wheels 7 and the wheel support brackets 12 can be prevented from protruding from the outer surface of the shelf 1.

Furthermore, since the connecting member 6 is installed at the same time as the column 4 and the lowermost shelf board 3 are connected, in other words, the wheels 7 are installed at the same time as the shelf 1 body is assembled, so that the movable shelf 1 as a whole The effort required for assembly will be reduced accordingly.

[Functions and effects of the idea]

The present invention is constructed as described above, and the side plate of the connecting member is interposed between the inner surface of the column and the outer surface of the corner of the lowest shelf board, and these three parts are integrally fastened with bolts. Then the wheels are installed.

At that time, since the length of one side of the base plate is greater than the width of the side plate of the column, in other words, the width of the side plate of the connecting member is greater than the width of the column, so the lowermost shelf is In addition, since the wheels are attached to a base plate that has a wider area than the bottom area of the column, the supporting area for the wheels is larger than when the wheels are simply attached to the bottom surface of the column, and the load is partially This prevents the particles from concentrating on each other and improves the support strength.

Also, since the width of the side plate of the connecting member is wider than the side plate of the column, the area where the base plate is not bent and deformed increases, so the grounding point of the wheel should be located toward the inside of the shelf rather than below the column. This means that even when large wheels are attached, the wheels and wheel support brackets can be prevented from protruding from the outer surface of the shelf.

Therefore, according to the present invention, since the lowermost shelf board and the column are reinforced by the connecting member, the rigidity of the shelf and the support strength of the shelf by the wheels can be improved, and
Since the wheels and wheel mounting members can be prevented from protruding from the outer surface of the shelf, it is possible to reliably prevent damage to the wheels and wheel mounting members and injury to people. Furthermore, since the wheels are attached at the same time as the shelf is assembled, the effort required to assemble the entire shelf can be reduced.
