[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk having a leg mounting structure .

[0002]

2. Description of the Related Art Conventionally, a desk is generally formed by combining a plurality of sheet metal-worked metal plates to form a leg body having a panel structure, and mounting a top plate on the leg body.

[0003]

In the above-mentioned desk, it is necessary to prepare a plurality of metal plates by sheet metal working in order to make the legs, and the metal plates after the sheet metal working are spot welded, rivets, caulked, etc. Since it is necessary to join them to each other, it takes a lot of man-hours and labor to assemble the legs, which causes a cost increase. Further, such a sheet metal assembly type leg body is difficult to obtain sufficient rigidity even if the number of joints such as spot welding is increased, so that it is necessary to provide a reinforcing frame inside, which causes the structure to become more complicated. Was becoming.

Accordingly, it is an object of the present invention to provide a desk which is simple in structure and assembly and which has high rigidity.

[0005]

According to the first aspect of the present invention, a panel-shaped rear side support for supporting the rear side portion of the side edge portion of the top plate, and the front side of the front end surface upper part of the rear side support are provided. The arm part that is projected to support the front part of the side edge of the top plate, the front leg part that protrudes forward from the lower part of the front end face of the rear support part, and the bottom part of the rear support part and the front leg part, respectively. With a height adjusting adjuster to be attached, the rear side support body, the arm portion and the front leg portion are each formed by integral molding of metal, and
Recesses formed in the arm and the front leg, respectively, and the rear support
Fit the upper part of the front end face and the convex parts formed on the lower part
Arms and front legs are positioned relative to the rear support Te,
Further, there is provided a desk comprising a leg body fixed by a screw for fastening the convex portion and the concave portion to each other .

In the leg body of the desk having the above-mentioned structure, since the rear side support body, the arm portion and the front leg portion are formed by integral molding of metal, each has sufficient rigidity, and the manufacturing process thereof. Is simplified. Further, the arm and the front leg are positioned with respect to the rear support by fitting the protrusion formed on the rear support and the recess formed on the arm and the front leg , and the protrusion and the recess. Since they are fixed by screws that fasten each other, a desk having highly rigid legs can be easily assembled.

According to the third aspect of the present invention, the top plate, legs supporting the left and right side edge portions of the top plate, and a cord case installed between the two legs along the lower surface of the rear portion of the top plate. A cord drawer cover attached to the upper surface of the cord case along the rear end of the top plate, wherein each of the two legs is a leg according to claim 1, and the cord case is one of the two legs with respect to the two legs. rear end portions of each formed engaging projections and code casing by the engagement of the respective formed engaging hole engaged with the two legs on the inner surface of the support member, the top plate, the front end of the two legs It is locked on both legs by the engagement of the engagement protrusion formed on the upper surface of the part and the engagement hole formed on the top plate, and the code case
On the other hand, there is provided a desk characterized by being fixed to a rear end surface of a top plate and an upper surface of a cord case by an attachment tool, and the attachment tool being covered by the cord drawer cover.

In the desk having the above structure, the leg body having high rigidity can be easily assembled, and the top plate and the cord case are locked to the leg body by the engagement of the engagement protrusion and the engagement hole. Since the top plate and cord case can be easily attached to the legs,
Since the attachment for fixing the base and the top plate is covered with the cord drawer cover, the appearance is also excellent.

Since the top plate 1, the cord case 3 and the rear panel 5 can be easily assembled to the legs 2 and 2 since they are locked by engaging with the top plates 17 and 21, the mounting for fixing the top plate 1 is also possible. Since the tool 18 is covered by the cord drawer cover 4, it becomes excellent in appearance.

FIGS. 7 to 9 show another embodiment of the desk according to the present invention and a leg used on one side thereof (the essential leg of the present application).
Is not) . In these figures, the same components as those in the above-mentioned embodiment are designated by the same reference numerals.

In the desk of this embodiment, one leg 2 has a panel-shaped rear support 6 for supporting the rear portion of the side edge of the top plate 1, and a front end surface of the rear support 6. A front support 24 that is provided on the front plate and supports the front part of the side edge of the top plate 1.
And height adjusters 9 and 10 attached to the bottoms of the rear side support 6 and the front side support 24, respectively, and the rear side support 6 and the front side support 24 are made of a light metal such as aluminum. The front support 24 is formed by integral molding, and the rear support 6 is formed with respect to the rear support 6.
A screw 1 which is positioned by fitting a convex portion 11 formed on the front end surface of the concave portion and a concave portion 12 formed on the rear end surface of the front support 24, and which tightens the convex portion 11 to the concave portion 12.
It is fixed by 3. In other words, the data of this example
In one leg of the disc, a front support 24 is attached to the rear support 6 instead of the arm 7 and the front leg 8 of the above-described embodiment.

Also in this embodiment, since the rear side support body 6 and the front side support body 24 are respectively formed by integral molding of light metal such as aluminum, each has sufficient rigidity and the manufacturing process thereof is simple. Be converted.
Further, since the front support 24 is positioned with respect to the rear support 6 by fitting the convex portion 11 and the concave portion 12 and is fixed by the screw 13 for fastening the convex portion 11 to the concave portion 12, a leg body having high rigidity. 2 can be easily assembled.

Further, as can be seen from the above description, since the front support member 24 has the arm portions 7 and the front leg portion 8 is compatible, the front support member 24 to the side support 6 after right or left leg 2 it can be attached. Therefore, when a plurality of desks are arranged in series, the arm portion 7 and the front leg portion 8 are attached to the rear side support bodies 6 and 6 of the legs 2 and 2 which are adjacent to each other, and the rear side support portions of the leg bodies 2 and 2 at both ends are supported. The front support 24, 2 is attached to the body 6, 6.
By mounting 4, it is possible to effectively use the lower space of the top plates 1, 1 ...

Further, since the rear panel 5 is detachable from the leg 2, the rear panel 5 of at least one of the desks may be omitted when arranging the two desks face to face, if necessary.

In the illustrated embodiment, the convex portion 11 is formed on the rear support 6 side and the concave portion 12 is formed on the arm portion 7, the front leg portion 8 or the front support body 24 side. The convex portion 11 is formed on the rear support 6 side, and the convex portion 11 is formed on the arm portion 7 and the front leg portion 8.
Alternatively, it may be formed on the front support 24 side. Further, the front support 24 is not limited to the rectangular panel shape shown in the figure, and may have any shape as long as it has a function of supporting the front portion of the side edge portion of the top plate 1 and a function of attaching the adjuster 10 to the front end of the bottom portion. You may have.
