Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a stainless steel workbench.

(Prior Art) Conventionally, this type of workbench is as shown in Fig. 10.
The legs are assembled by welding the support legs a and the horizontal beams b that connect the support legs, and the legs are welded to the top plate c, or the entire assembly is performed by a welding process, or alternatively, as shown in Fig. 11. Assemble the legs by welding,
Screw the horizontal bar b of the same leg onto the top plate c as shown by the arrow.
They are connected and assembled using bolts.

In the figure, d is an azimuth star.

(Problems to be solved by the invention) However, the former has a complicated manufacturing process and cannot be disassembled, which is disadvantageous when storing in warehouses, factories, etc., and when transporting.

The latter has the advantage of omitting part of the welding process, but since the legs and the top plate are connected with screws and bolts, it lacks rigidity, and there is a risk that the supporting legs may deform from the part where they are attached to the top plate. There is.

The present invention has been proposed in view of the problems of the prior art, and its purpose is to:
The object of the present invention is to provide a workbench that has sufficient rigidity and is convenient for storage and transportation.

(Means for Solving the Problems) In order to achieve the above object, the workbench according to the present invention includes a reinforcing member having a square cross-section, which is formed by extending horizontal pieces from the upper ends of both sides of a groove-shaped piece. , a nut seat plate with a groove-shaped cross section is disposed on the back surface of the top plate in the longitudinal direction and is welded through the horizontal piece, and in the hollow part of the reinforcing member, a nut is welded on the bottom piece. A joint piece with a groove-shaped cross section that is fitted and welded and horizontally protrudes from the upper end of the support leg is fitted to the reinforcing member such that a gap exists between each of the bottom pieces, and the joint piece and The tip of a bolt inserted through the reinforcing material and the nut seat plate is screwed and tightened into the nut of the same nut seat plate, and the tip edge of both sides of the joint piece with the groove-shaped cross section is inserted into the reinforcing material with the square cross section. It is constructed by being crimped onto a horizontal piece of the

(Function) Since the workbench according to the present invention is constructed as described above, the reinforcing material with the square cross section is disposed on the back surface of the top plate in the longitudinal direction and welded through the horizontal part. A joint piece with a groove-shaped cross section that protrudes horizontally from the upper end of the support leg is fitted so that a gap exists between the bottom pieces of both, and the tip of the bolt inserted through the joint piece and the reinforcing member is inserted. By screwing and tightening the nut welded onto the bottom piece of the groove-shaped cross-section nut seat plate, the joint piece with the groove-shaped cross-section is pulled toward the top plate. The end edges of both sides of the pieces are crimped to both horizontal pieces of the reinforcing material with a square cross section welded to the top plate, and the joint pieces and the reinforcing material are integrally attached to the top plate. As a result, the rigidity of the supporting leg attachment portion is increased, and there is no risk that the supporting leg will be displaced or deformed from the attachment portion of the top plate.

Further, by removing the bolts, the workbench can be disassembled into the top plate and the supporting legs.

(Example) The present invention will be described below with reference to the illustrated embodiments.

Reference numeral 1 designates a top plate, and on its back surface, a reinforcing member 2 having a cross-sectional shape in which horizontal pieces 2a are extended from the upper ends of both sides of a groove-shaped piece is arranged in the longitudinal direction, and the horizontal pieces 2a is welded through.

A nut seat plate 3 having a groove-shaped cross section is fitted and welded to the reinforcing member 2, and a nut 4 is welded to the bottom plate of the seat plate 3.

5 is a support leg, and the upper and lower parts of the adjacent support legs 5 are connecting members 6
The left and right legs are assembled. Furthermore, the base end of a horizontal joint piece 7 having a groove-shaped cross section is welded to the upper end of each support leg 5, spanning the upper connecting member 6.

Incidentally, bolt holes are bored in the joint piece 7, the reinforcing member 2, and the nut seat plate 3 at positions corresponding to the nuts 4.

In the figure, reference numeral 8 denotes a horizontal crosspiece that is detachably connected between the supporting legs 5 facing each other on the left and right sides via bolts 9, and 10 is an adjuster star.

Note that each of the above-mentioned members is made of stainless steel.

Since the illustrated embodiment is constructed as described above, when assembling, the joint piece 7 is fitted to the reinforcing member 2 so that a gap exists between the bottom pieces of both members, and the joint piece 7 and the reinforcement When the bolt 11 is inserted through the material 2 and the nut seat plate 3, and the tip of the bolt 11 is screwed into the nut 4, the joint piece 7 is drawn toward the top plate 1 as shown in FIG. The leading edges of the side pieces are crimped to the horizontal piece 2a of the reinforcing member 2, and the reinforcing member 2, the joint piece 7, and the top plate 1 are integrated, and the rigidity of the supporting leg attachment portion is increased. There is no risk of deformation or displacement from the top plate mounting part.

To explain this point in more detail, suppose that, as shown in FIG. When fastened, a gap t exists between the tip edges of both side pieces of the joint piece 7 and the back surface of the top plate 11, and the support leg 5 and the bottom piece of the reinforcing member 2 are shown in FIGS. 7 to 9. However, as in the above embodiment, the bolt 11 inserted through the joining piece 7 and the reinforcing material 2 is screwed into the nut 4 welded to the nut seat plate 3 fitted to the reinforcing material 2. By tightening and tightening both sides of the joint piece 7 to the horizontal piece 2a of the reinforcing member 2, the rigidity of the attachment part of the support leg 5 to the top plate 1 is increased, and the displacement of the support leg 5 is increased. , which can reliably prevent deformation.

(Effects of the invention) According to the invention, as described above, a nut seat plate with a groove-shaped cross-section and a nut welded to the bottom piece is fitted and welded to the reinforcing material with a square-shaped cross-section welded to the back surface of the top plate. A joint piece with a groove-shaped cross section protruding from the upper end of the support leg is fitted to the reinforcing member such that a gap exists between the bottom pieces of both, and a bolt is inserted through the joint piece and the reinforcing member. By screwing and tightening the nut into the nut provided on the nut seat plate, the joint piece is drawn toward the top plate, and both sides of the joint piece are welded to the top plate of the reinforcing material of the cross section. By crimping the support leg to the horizontal piece, the rigidity of the attachment portion of the support leg to the top plate is increased, and displacement and deformation of the support leg can be prevented.

Further, according to the present invention, by removing the bolts, it can be disassembled into the top plate and the supporting legs, making it easy to store and transport.
