Description

[Detailed description of the invention] The present invention is a lower part reinforcing device for the main body of a desk sleeve, that is, a metal plate is bent into a substantially U-shape in plan view to form a body plate with a front opening, and an upper bent edge of the body plate is formed. In a sleeve body in which a top plate is attached to the top, a bottom plate is attached to the lower bent edge, and an extractor is attached from the front opening, the attachment of the legs is not possible due to the load of the sleeve body and extractor that is applied to the support legs attached to the bottom surface of the bottom plate. The aim is to strengthen the structure so that it does not undergo deformation such as concave bending.

Referring to the accompanying drawings, first, the body plate 1 is approximately U-shaped in plan view, with an opening at the front and bent edges 2 and 3 at the top and bottom, as shown in FIG. Both side plates 4,
A front strut 5 is formed at the front end of the inner side of the frame 4, and a rear strut 6 is formed at the rear end thereof symmetrically by welding the shapes.
and reinforcing protrusions 10, 1 of the bottom plate 7 to be described later at the lower ends of 6, 6.
0, and several pairs of left and right extractor rails (not shown) are provided on the inner surfaces of the front and rear supports 5, 6 on both the left and right sides.

Next, as shown in FIG. 1, the bottom plate 7 has a bent stile 9 at its front end, and reinforcing protrusions 10, 10 located below the notches 8 of the pillars 5, 6 on the front and rear upper surfaces. , and has convex rib stripes 11, 11 and protruding ribs 12..., which are installed by expanding the front opening of the body plate 1 laterally and placing and welding it on the lower bent edge 3. , Reinforcement protrusion 10.10
Each support leg (
(not shown) is mounted across the lower groove 10' of the reinforcing ridge 10 by using screw holes 19 and 19 located diagonally to each other through the reinforcing ridge 10.

According to the above configuration, the supporting legs of the bottom plate 7 are attached to the protruding ribs 12 at the portions.
..., and the notches 8 of the columns 5 and 6 are supported in a fitted state on the upper surface of the reinforcing protrusion 10, thereby reinforcing the load reaction force from the supporting legs. Convex strip 10
The bottom plate 7 is received at the lower ends of the pillars 5 and 6 through the support legs, thereby ensuring that the bottom plate 7 is not deformed when the support legs are attached.

However, since the sleeve body uses a roughly U-shaped body plate and has a front opening, the strength of the front part needs to be greater than that of the rear part, so in this case, as shown in Figure 5, A reinforcing metal fitting 14 is attached between the front support column 5 and the front reinforcing protrusion 10.

That is, the reinforcing metal fittings 14 include a vertical piece 15, a bent horizontal piece 16, and a hanging piece 1.
The vertical piece 15 is attached to the front column 5 in advance by welding it to the front column 5, and the bent horizontal piece 16 is attached to the column 5 in advance.
A gap is formed between the lower end notch 8 of the support column 5, and the upper plate of the reinforcing ridge 10 of the bottom plate 7 is fitted into this gap as shown in FIG. It is attached by welding to the groove 10'.

Incidentally, the bottom plate 7 must be provided with a slit 18 into which the vertical piece 15 is fitted, as shown in FIGS. 1 and 4.

According to the present invention as described above, the front and rear supports 5 and 6 provided on the body plate 1 are attached to the reinforcing protrusions 1 formed on the bottom plate 7.
0 and 10, even if an upward reaction force is applied to the bottom plate 7 due to the load applied to each support leg, the upward reaction force is received by the columns 5 and 6 via the reinforcing ridges 10, and the bottom plate 7 There is no risk of deformation of the support leg attachment part, and in the front part, which requires greater strength than the rear part, reinforcing metal fittings 14 are used to connect the reinforcing protrusions 10 of the pillar 5 and the bottom plate 7. As a result, the reaction force of the load applied to the support leg can be reliably received by the support column 5, thereby preventing the bottom plate 7 from deforming.
