Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a desktop shelf device for forming a shelf above a desk top plate, and more particularly to a desktop shelf device for a desk on which a heavy object such as a CRT is placed on a shelf, such as a dealing desk.
[0002]
[Prior art]
Conventionally, when desk work is performed, a CRT or the like is placed on the desk surface in accordance with the OA. However, a considerable desk space is required due to the size, and the work space is narrowed.
Also, if you have to use multiple OA devices such as CRTs such as dealing desks, if you cannot put all the devices on the desk, you must put them under the desk or next to the desk, Not only was the work efficiency worsened, but the 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-like shelf having a sufficient depth of the side plate is placed and a heavy object such as a CRT is placed thereon as a desk shelf.
[0003]
[Problems to be solved by the invention]
In the above-described conventional desk desk shelf, there is no problem in supporting heavy objects, but the side plate having a large depth hinders effective use of the top surface of the desk, and the shelf height cannot be changed.
[0004]
An object of the present invention is to provide a desktop shelf apparatus that can change the height and withstand the placement of heavy objects without impairing the effective area of the top board.
[0005]
[Means for Solving the Problems]
According to the present invention, the above problem is solved as follows.
(1) A first column portion provided with a plurality of vertical bracket locking holes on the front surface of the shelf column, and a first column portion provided behind the first column portion and connected thereto. And a contact portion facing forward is provided at the lower end of the first support column portion, and the contact portion is contacted with the upper surface of the table leg to receive the load of the shelf support column. And a fitting insertion portion projecting from the lower end of the second column portion , and the fitting insertion portion is fitted into a vertical fitting portion provided at an appropriate position on the rear portion of the table leg , and the table leg and the screw are inserted. By stopping, the shelf column is erected above the rear part of the table pedestal , and the shelf board is changed in height via a bracket facing forward on the front of the column column erected on the left and right table legs. Install as possible.
[0006]
(2) In the above item (1), the contact portion of the first strut part screwed into Tsukueashi, a second strut portion of inserting portion, is screwed to the Tsukueashi at upper and lower locations .
[0007]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a perspective view showing an embodiment in which two dealing desks (A) having a desktop shelf device (1) of the present invention are juxtaposed. In this embodiment, the middle pedestal (2) of the two dealing desks (A) is shown as short only at the rear, but generally the pedestal (2) is shown at both ends. The length extends to the front edge of the desk.
[0008]
At the corner of the rear end of the dealing desk (A), a shelf column (3) is erected, and a plurality of vertical slits, that is, arbitrary heights of slits (4) are formed in the front surface thereof. A bracket (5) is engaged with the left and right brackets (5) attached to the left and right brackets (5) in this way, and a shelf board (6) is stretched over them.
[0009]
FIG. 2 is an enlarged partial perspective view of the rear end of the left pedestal (2) in FIG. 1 as seen from the rear, showing a state in the middle of inserting the leg support (3) into the pedestal (2). Yes.
Incidentally, the top plate on Tsukueashi (2) is omitted.
[0010]
The table pedestal (2) has a U-shaped vertical member (7) which forms the structural material, and an upper horizontal member (8) having a U-shaped cross section fixed to the vertical member (8) by welding or the like. In the case of the example, the vertical member (7) has the U-shaped opening facing backward, and the upper horizontal member ( 8 ) has the U-shaped opening facing upward.
[0011]
The leg strut (3) is connected to the first strut portion (3a) having a plurality of slits (4) for locking the brackets in the vertical direction on the front surface and the rear of the first strut portion (3a). And a second column portion (3b) having a fitting insertion portion (11a) projecting from the lower end thereof.
[0012]
The first strut portion (3a) is made of a steel material (9) having a substantially U-shaped cross section and having a plurality of slits (4) arranged in the center in the vertical direction. A horizontal abutting piece (10) facing forward is continuously provided at the lower end of 9).
[0013]
The second strut portion (3b) has a U-shaped steel material (11) as a main component, and the lower end portion of the steel material (11) protrudes downward longer than the lower end of the first strut portion (3a). The insertion part (11a) is closely inserted into the fitting part formed by the inner surface of the U-shaped vertical member (7) of the table leg (2).
[0014]
The steel material (9) and the steel material (11) are covered with a covering material (12) such as a thin steel plate (in the illustrated embodiment, the three covering materials are bent), and a space portion is separated inside. First and second strut portions (3a) and (3b) connected on the outside are formed.
[0015]
As shown in FIG. 2, the leg strut (3) having such a structure has the fitting portion (11a) of the second strut portion (3b) placed in the vertical member (7) of the table leg (2). The three surfaces are fitted in close contact with each other, and are fastened with bolts (14) and fixing nuts (15) at two height positions.
After this fastening, a cover (16) is fitted into the open part of the rear surface of the vertical member (7) to cover the rear surface.
The fixing nut (15) may be attached to the table leg (2) side by welding, and the bolt (14) may be inserted from the leg column (3) side.
[0016]
At this fixed height position, the abutting piece (10) at the lower end of the first column portion (3a) abuts on the bottom surface of the upper horizontal member (8) of the table leg (2). ).
[0017]
【The invention's effect】
According to the present invention, a heavy object such as a CRT can be placed on a desk shelf stably and in good appearance, and can be used to the maximum extent on a table top. In addition, since the bracket can be mounted at any height position, the shelf height can be set and changed freely, and if the shelf is not required, the whole can be removed to make a normal flat table. it can.
[0018]
Moreover, the load of a heavy article is received by the contact part, and an extra burden is not imposed on the attachment part of the second column part to the table leg.
[0019]
According to the second aspect of the present invention, the table base and the shelf column can be integrated without the shelf column being wobbled by the longitudinal force acting on the shelf column.
