Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk shelf device for forming a shelf above a desk top plate, and
The present invention relates to a desk shelf device on which a heavy object such as a CRT is placed on a shelf.

[0002]

2. Description of the Related Art Conventionally, when desk work is performed, a CRT or the like is placed on a desk surface in accordance with OA, but the size of the desk takes a considerable amount of space on the desk, and the working space is narrowed. . Also, when a plurality of OA devices such as a CRT must be used like a dealing desk, and when it is not possible to place all the devices on a desk, they must be placed under a desk or beside a desk. Not only was the work efficiency inferior, but space was also limited in this way, so many could not be placed. For this reason, in a conventional dealing desk or the like, a box-shaped shelf having a sufficient depth of a side plate is placed and a heavy object such as a CRT is placed on the shelf as a desk shelf.

[0003]

In the above-mentioned desk shelf of the conventional dealing desk, although there is no problem in supporting a heavy object, the effective use of the top plate surface of the desk is hindered by the large depth side plate, and the shelf is also difficult. The height could not be changed.

[0004] It is an object of the present invention to provide a desk shelf device which does not impair the effective area of the top plate, can be changed in height, and can withstand heavy loads.

[0005]

According to the present invention, the above-mentioned problem is solved as follows. (1) A plurality of locking holes for locking the bracket are provided on the front surface in the vertical direction, and a shelf support with a fitting insertion portion projecting from the lower part is attached to a vertical fitting portion provided at an appropriate position at the rear of the desk leg. By inserting the fitting portion and screwing it to the desk leg, the shelf plate is erected above the rear part of the desk leg, and the shelf plate is heightened via a bracket on a shelf support standing upright on the left and right desk legs. It is installed so that it can be changed.

(2) In the above item (1), a shelf support is provided on a first support portion having a plurality of locking holes for locking a bracket on the front surface in a vertical direction, and at a rear portion of the first support portion. A second support portion provided in connection with the first support portion and having a lower portion with a fitting portion protruding therefrom, and a lower end of the first support portion being in contact with a table leg and receiving a load. Is provided.

(3) In the above item (2), the contact portion of the first support portion is screwed to the desk leg, and the insertion portion of the second support portion is screwed to the desk leg at two upper and lower positions. I do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a desk shelf apparatus (1) of the present invention.
FIG. 1 is a perspective view showing an embodiment in which two dealing desks (A) each having a desk are arranged side by side. In this embodiment, the middle desk leg (2) of the two dealing desks (A) is shown as being short at the rear only, but generally the desk legs (2) are shown at both ends. It extends to the front end of the desk.

At the rear end corner of the dealing desk (A), a shelf support (3) is erected, and a plurality of slits, ie, locking holes (4) formed in the longitudinal direction on the front surface thereof. The bracket (5) is engaged with the bracket (5), and the shelves (6) are hung over the left and right brackets (5) attached in such a manner as to have the same height.

FIG. 2 is an enlarged partial perspective view of the rear end of the desk leg (2) at the left end of FIG.
(2) shows a state during insertion. Although the top plate on the table leg (2) is shown in a state where it is omitted, the top plate is attached so as to expand as indicated by a chain line.

The desk leg (2) has a vertical member (7) having a U-shaped cross section as a structural material thereof, and an upper horizontal member (8) having a U-shaped cross section fixed to the vertical member (7) by welding or the like. In this embodiment, both the vertical member (7) and the upper horizontal member (8) have their U-shaped openings facing outward.

The leg support (3) has a first support portion (3) provided with a plurality of slits (4) for locking the bracket on the front surface in a longitudinal direction.
a) and a second support portion (3a) provided behind and connected to the first support portion (3a) and having a fitting portion (11a) projecting from the lower end thereof.
b).

The first pillar portion (3a) has a steel member (9) having a substantially U-shaped cross-section and a plurality of slits (4) arranged vertically in a central portion thereof as a main constituent member. The steel material
At the lower end of (9), a horizontal contact piece (10) facing forward is continuously provided.

The second support portion (3b) is made of a steel material having a U-shaped cross section.
(11) is the main component, and the lower end of this steel material (11) is
Protruding downward from the lower end of the column part (3a) of the
And a fitting portion (11a) closely fitted into a fitting portion formed by the inner surface of the U-shaped vertical member (7).

The steel material (9) and the steel material (11) are covered with a coating material (12) (three bent coating materials in the illustrated embodiment) such as a thin steel plate, and have a space inside. First and second strut portions (3a) and (3b) connected on the outside with a space therebetween
Is formed.

As shown in FIG. 2, the leg support (3) having such a structure has a fitting portion (11a) of the second support portion (3b).
Fit the three surfaces into the vertical member (7) of the table leg (2) so that the three surfaces are in close contact with each other. At the two upper and lower positions, the bolt (14) and the fixing nut
Fastened by (15). After this fastening, the vertical member (7)
The cover (16) is fitted into the opening on the rear surface to cover the rear surface. Preferably, the fixing nut (15) is attached to the desk leg (2) by welding, and the bolt (14) is inserted from the leg support (3) side.

At the fixed height position, the first column portion (3
The contact piece (10) at the lower end of a) is the upper horizontal member (8) of the desk leg (2).
It is good to fasten this with the bolt (13) because it comes into contact with the bottom surface of the.

[0018]

According to the present invention, a heavy object such as a CRT can be stably placed on a desk shelf, and can be placed in a good format, and can be used to the maximum extent on a tabletop. In addition, since the bracket can be mounted at any height position, the height of the shelf can be set and changed freely, and when the shelf is not required, the entire shelf can be removed to make it a normal flat desk it can.

According to the second aspect of the present invention, the load of the heavy object is received by the abutting portion, so that no extra load is applied to the portion of the second support portion attached to the table leg.

According to the third aspect of the present invention, the table legs and the shelf support can be integrated without causing the shelf support to fluctuate with respect to the longitudinal force acting on the shelf support.
