Description

[Detailed Description of the Invention] This invention relates to an assembly structure for a cabinet made of metal members, hard resin, or the like.

A conventional cabinet of this kind, although not shown,
Attach short L-shaped pillar mounting brackets to the four corners of the bottom plate, and use these as supporting materials to erect pillars from angle materials at the four corners of the bottom plate. By placing the top plate on top plate, fixing the vertical edge plates and pillars around the four sides, and constructing horizontal members made of strips or angle materials between the pillars,
The base was constructed. In this case, the angle pillar mentioned above does not have flat attachment parts at the top and bottom ends, so
When installing casters at the outer bottom corners of the cabinet, choose another location instead of directly mounting them to the pillars. This prevents the caster from directly receiving the load of the cabinet on the pillar. Therefore, the four corners of the bottom of the cabinet are deformed into a wavy shape due to the misalignment between the part of the bottom plate that receives the load via the pillars and the part of the caster that receives the load applied to the bottom plate.

Furthermore, for the reasons mentioned above, the suspension bolts for lifting and moving the cabinet are not attached to the pillars but at other locations. As a result, when the cabinet is moved via the suspension bolts, the suspension load is applied to the suspension bolts that are separated from the pillars, causing the top plate of the cabinet to deform in a pinched-up manner. In this way, the base of the cabinet lacked the required strength. To compensate for this, in the past, the bottom plate and top plate were made thicker, which resulted in the problem of increased weight.

Furthermore, the above-mentioned configuration requires members such as pole mounting brackets and cross members, which increases the number of parts, takes a long time to assemble, and also makes assembly complicated and difficult to work with, resulting in high costs. There was a problem.

This invention was made to solve each of the above problems, and its purpose is to:
By arranging planar U-shaped bone members that also serve as pillars at the four corners between the bottom plate and the top plate, casters and hanging bolts can be directly attached to the bone members, increasing strength and eliminating the need for conventional pillar mounting. It is possible to reduce costs by eliminating the need for metal fittings and horizontal members, and in addition, a lid with a wire outlet hole is removably fitted into the open part of the above-mentioned frame member to form a wiring duct. An object of the present invention is to provide a cabinet assembly structure in which electric wires that can be electrically connected to a power source can be stored and organized in a bundle.

An embodiment of this invention will be described below with reference to the accompanying drawings.

First, to explain the configuration, mounting holes 1' and 1'' are provided at the four corners of the bottom plate 1, and the following bone members 2 are erected on the corner surfaces.
As shown in FIG. 4, by extrusion molding a light metal material, hard resin, or the like, a plane having an open portion on the front is formed into a roughly U-shape. A large-diameter main bolt hole 2a with female threads 2a' and 2a'' provided at the upper and lower ends is provided in the side wall body on one side near the open part in the longitudinal direction.The main bolt hole 2a
The inner part of the side wall body on one side close to the position and the side wall body on the other side opposite to that position have female threaded parts 2
Sub-bolt holes 2b, 2c of somewhat smaller diameter are provided with holes b', 2b'', 2c', 2c'' extending parallel to each other in the longitudinal direction. Furthermore, on the outside of both side walls near the edges of the open part, grooves 2f for mounting chassis slide rails, etc., and mounting grooves 2g used for inserting nut bars and mounting panels, etc. are provided in the longitudinal direction. .

The lower main bolt hole 2a″ of the bone member 2 has a third
As shown in the figure, for the purpose of attaching the bottom plate 1, a caster 3 having a threaded portion 3' at its upper end is directly screwed by the threaded portion 3' through the bottom plate hole 1'.
Further, in order to further tighten the bottom plate 1 and the frame member 2, mounting bolts 6, 6 are directly screwed into the lower subordinate bolt holes 2b'', 2c'' through the bottom plate holes 1'', respectively.

Next, in the upper main bolt hole 2a' of the bone member 2, a second
As shown in the figure, the threaded portion 5' of the suspension bolt 5 is directly screwed through the top plate hole 4' to also serve as the attachment of the top plate 4. In this case as well, the upper secondary bolt hole 2
b', 2c' are provided with mounting bolts 6', 6' of the same shape as the above, respectively, in order to further tighten the top plate 4 and the frame member 2 through the top plate holes 4'' made in the top plate 4. Directly screwed in.

In this way, the frame members 2, which also serve as columns, are arranged between the four corners of the bottom plate 1 and the top plate 4, thereby forming the base of the cabinet. 7 is a side plate, and 8 is a door.

On the other hand, in the open part of the bone member 2 located at an appropriate position inside the cabinet,
As shown in FIGS. 1 and 4, a resin-molded (or metal) duct cover 9 is removably fitted to form a wiring duct. In this case, as shown in FIG. 5, the duct lid 9 has engaging recesses 9a and 9b protruding from both sides of the band-like surface for engaging with the locking projections 2d and 2e of the bone member 2, respectively. . Further, in the front part of the duct cover 9, there is a wire extraction hole 9c.
are provided at appropriate intervals. 10 is a chassis case, and 11 is a panel.

With the above configuration, even if the load of the cabinet is transferred to the bone member 2 serving as a column, the caster 3 is attached to the bottom position of the bone member 2, so that the load is not directly borne by the caster 3. Become. That is, the part of the bottom plate 1 that receives the load via the bone member 2 and the part of the caster 3 that receives the load when the load is applied to the bottom plate 1 are This is due to the result of convergence at the same position. Thereby, deformation of the bottom plate 1 due to the load of the cabinet can be reliably prevented.

Also, when lifting and moving the cabinet,
The hanging load is concentrated on the hanging bolt 5, but in this case as well, since the hanging bolt 5 is screwed directly to the frame member 2 via the top plate 4, the hanging load does not spread to the top plate 4. There isn't. Therefore, deformation of the top plate 4 due to lifting movement can be reliably prevented.

Furthermore, since the frame member 2 is formed into a roughly U-shaped plane, the open part becomes a wiring duct by attaching the duct cover 9, so that each electric wire that can be electrically connected to an external power source can be Not only can the wires be stored and organized in a bundle, but each wire can be protected from accidental damage, improving safety.Furthermore, the wires inside can be separated and pulled out according to the required height through the hole 9c of the lid 9. So,
This eliminates the need for wire bundle work, etc. for internal wiring, shortens wiring work time, improves safety, and allows clean processing. Moreover, since the bone member 2 has a substantially U-shaped planar structure, it is excellent in strength, and the U-shaped structure has the advantage of saving materials and being suitable for mass production.

As explained above, this idea has been developed by placing bone members that penetrate in the longitudinal direction and have bolt holes at the same positions on the upper and lower ends at the four corners between the bottom plate and the top plate, so that casters and hanging bolts can be easily fixed. can be attached directly to the bone member to increase strength. Furthermore, since no load is directly applied to the bottom plate or the top plate, both plates can be made from thin materials, which reduces the weight of the cabinet and saves on materials. Moreover, since the frame member is formed into a roughly U-shape in plan, the open part becomes a wiring duct by fitting the duct cover, and the electric wires can be stored and organized in a concentrated manner, and each electric wire can be unintentionally separated. Protect from damage. In addition, since the duct cover has a wire extraction hole,
It eliminates the need for bundling internal wiring, reduces wiring time, and is also excellent in safety. Furthermore, there is no need for conventional pillar mounting brackets, cross members, etc., and assembly is easy and workable, and assembly time can be shortened, resulting in a significant cost reduction.
