DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table mounting bracket used for an electronic equipment open rack having a table mounted between vertical frames.

[0002]

2. Description of the Related Art To mount a wooden table between vertical frames such as an open rack for electronic equipment, an iron angle 1 is screwed to a vertical frame 2 as shown in FIG. The usual method is to place the table 3 and screw it from the lower surface. However, in this case, the screws 4 and 5 for mounting are visible from the outside and unsightly.
Therefore, there is a problem that a large amount of material is required because it is necessary to make the length approximately as long as the depth dimension.

Further, as shown in FIG. 7, the table 3 is made of iron, and mounting holes are provided on both end faces thereof.
In this case, the width a of the table 3 is set to the distance b between the vertical frames 2 on both sides.
Therefore, there is a problem that high dimensional accuracy is required for the processing of the table 3 and assembly and removal of the table 3 are not easy.

Further, when an option 6 such as a wiring duct or a fall prevention bar is attached to the table 3 as shown in FIG. 8, it is necessary to insert an embedding nut 7 into the table 3 or to perform tapping, which is troublesome. There was a problem.

[0005]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and has a good appearance without mounting screws, requires less material, and does not require a high dimensional accuracy for the table. The purpose of the present invention is to provide a table mounting bracket that allows easy mounting of options.

[0006]

The table mounting bracket according to the present invention, which has been made to solve the above-mentioned problems, comprises:
A table for attaching a table between the vertical frames on both sides
Bull mounting bracket, a relatively short upper horizontal plate and a lower horizontal plate extending longer than the vertical plate fixed to the vertical frame, the lower horizontal plate of the table inserted between them While protruding at intervals slightly larger than the plate thickness to form a U-shaped portion for holding the edge of the table,
This forms a one step deeper grooves than the end face strikes the surface of the table in a vertical plate, a screw insertion hole provided in the groove, further grooves the containers for the optional attachment on the lower surface of the lower horizontal plate
It is characterized by being provided integrally in the direction of the edge of the table held by the character-shaped portion .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below. FIG. 1 is a perspective view of an open rack for electronic devices using the bracket of the present invention, and FIG. 2 is an enlarged view of a main part thereof. In these figures, reference numeral 2 denotes a vertical frame, and reference numeral 3 denotes a table attached between the vertical frames 2 on both sides. In this case, a wooden table is used. Reference numeral 10 is a table mounting bracket according to the present invention.

The table mounting bracket 10 of the present invention.
Is made of extruded aluminum, for example, and as shown in FIG.
13 protruding. The upper horizontal plate 12 is relatively short, and the lower horizontal plate 13 extends long, forming a U-shaped portion 14 as a whole. The edge of the table 3 is inserted and held in the U-shaped portion 14. Upper and lower horizontal plates 1
If the interval between 2 and 13 is slightly larger than the thickness of the table 3, the table 3 can be easily inserted and the table 3 can be held without rattling. Therefore, even if the length of the bracket 10 is shorter than the depth of the table 3, there is no possibility that a problem in strength occurs.

The vertical plate 11 is formed with a groove 15 which is one step deeper than the surface on which the end face of the table 3 contacts, and a screw insertion hole 16 is provided in the groove 15. The bracket 10 is fixed to the vertical frame 2 by passing a mounting screw 17 through the screw insertion hole 16. The depth of the groove 15 is set so that the head of the screw 17 enters the groove 15 in the mounted state. The mounting height of the table 3 can be freely changed. It is also possible to freely change the mounting position of the table 3 in the longitudinal direction of the bracket 10.

As shown in FIGS. 2 to 5, an optional mounting groove 18 is provided on the lower surface of the lower horizontal plate 13.
The table 3 is integrally provided in the direction of the edge of the table 3 held by the U-shaped portion 14 . The groove 18 has a structure in which a nut 19 can be accommodated from the end thereof at its lower end. FIG. 3 shows a state in which the optional fall prevention bar 20 is attached with the screw 23 using the groove 18. FIG. 4 shows a state in which an optional table reinforcing plate 21 is attached using the groove 18. The table reinforcing plate 21 is an option for closely contacting the lower surface of the table 3 so that the table 3 does not bend even when a heavy object is placed. Further, FIG.
8 shows a state in which an optional wiring duct 22 is attached by using the wiring duct 8. Since the option mounting groove 18 is provided integrally with the bracket 10 as described above, it is not necessary to insert a buried nut into the table 3 or to perform tapping as in the related art even when the option is mounted.

[0011]

As described above, by using the table mounting bracket of the present invention, the edge of the table can be restrained from above and below, so that the strength can be maintained even if the length of the bracket is shortened. No material waste occurs. Further, since the edge of the table is held by the U-shaped portion, the table can be reliably held even if the dimensional accuracy of the table is poor. Also, the mounting screws are not visible from the outside as in the past,
The table and bracket are integrated into a thin, neat design. Moreover, since the option mounting groove is provided on the lower surface of the lower horizontal plate, various options can be mounted without the need for secondary processing on the table as in the related art.
