Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk suitable for detachably mounting a desktop panel or the like for use.

[0002]

2. Description of the Related Art Conventionally, this type of desk is constructed by supporting a top plate on the desk body, and at the left and right corners on the rear end side of the desk body.
An internal through hole larger than the external dimensions of the legs of the desktop panel is provided, and the legs at both ends of the desktop panel are simultaneously inserted into the through holes to attach and detach the desktop panel near the back edge of the top plate. It is possible to install. With such a structure, the leg portions can be easily inserted into the through holes at the same time on the right and left sides. The desktop panel is fixed by using two or three bolts that tighten the legs from the front side of the desk body in the horizontal direction toward the back side.

[0003]

However, in the above configuration, when tightening the bolts for fixing the desktop panel, it is very difficult to work by putting a hand inside the rear end side of the desk body, and in some cases. Sometimes required special tools and jigs. Therefore, there is a demand for a structure in which the legs of the desktop panel are fixed only by retaining locks that can be operated from above so that they will not come out upward. However, as described above, if the inner diameter of the through hole is larger than the outer dimension of the leg portion, there is a possibility of rattling left and right and front and back if it is fixed only by retaining from above, which is not practical. Further, if the inner diameter of the through hole is made substantially the same as the outer dimension of the leg portion, and when the desktop panel is mounted on the desk body, if there is a dimensional error in the leg portion, the leg portion is simultaneously opened through the through hole. It is difficult to fit in.

An object of the present invention is to eliminate such a problem.

[0005]

The present invention takes the following means in order to achieve such an object. That is, the desk according to the present invention comprises a desk body and a top plate supported by the desk body, and the legs of the desktop panel are fitted into through holes provided at both left and right corners on the rear end side of the desk body. In a desk that can be used, the through hole is formed by a substantially rectangular opening, and the dimension of the substantially central portion in the longitudinal direction thereof is shorter than the dimension of the left and right ends.

In the present invention, it is preferable that the through holes are formed in flat plates arranged in parallel in upper and lower two stages. In that case, the size of the substantially central portion of each through hole in the longitudinal direction is
The thickness may be substantially the same as the thickness of the legs of the desktop panel.

[0007]

With such a structure, since the substantially central portion of the through hole in the longitudinal direction is shorter than the left and right ends, the leg portion of the desktop panel or the portion where the through hole of the desk body is provided is provided. Even if there is a slight dimensional error, it is possible to fit the left and right legs into the through holes at the same time. In particular, when the size of the central portion of the through hole in the longitudinal direction is set to be substantially the same as the outer dimension of the leg portion of the desktop panel, when the left and right leg portions are fitted into the through hole, the respective leg portions are Since it is held in the center of the through hole, the desktop panel can be held without rattling.

A nut is welded to the position corresponding to c. 8d
Is a groove into which a lid member for closing the cutout window 8a is inserted.

The through hole 10 is formed in the fitting member 11 forming the rear end portion of the side panel 2. This fitting member 11 is for fitting a cylindrical optional mounting bracket (not shown) and for mounting the desktop panel 2. One fitting member is fixed to the rear end side of the side panel 2. After the sheet metal is subjected to a predetermined press working, the sheet metal is bent and formed so as to have a substantially U-shaped cross section.
Therefore, the fitting member 11 includes the upper plate portion 11a, the lower plate portion 11b parallel to the upper plate portion 11a, and the upper plate portion 11a.
And a vertical plate portion 11c connecting the lower plate portion 11b. The round holes 11d and 11e are holes into which the optional attachment fittings are inserted. The through hole 10 is the upper plate portion 11 of the fitting member 11.
a is formed on the lower plate portion 11b at the same position.
2 is drilled. Each of the through holes 10 and 12 has the same shape, and has a substantially rectangular shape as shown in FIG. 3A, and the dimension in the longitudinal direction of the through hole 10 and 12 is that of the leg portion 9b shown by an imaginary line. The width L is larger than the width, and the dimension L of the substantially central portion is shorter than the dimension l of the left and right ends, and is substantially equal to the leg portion 9.
It is the same as the thickness dimension of b.

The desktop panel 9 is formed by attaching angle members 9c to the left and right ends of the panel portion 9a. The leg 9b is welded to the lower end of the angle member 9c. As shown in FIGS. 4 to 5, the leg portion 9b is formed of a first leg member 91 welded to the angle member 9c and a second leg member 92 welded to the lower end portion thereof. The first leg member 91 and the second leg member 92 are connected so that the front surface and the back surface are in close contact with each other, and the leg portion 9b formed by the front surface of the first leg member 91 and the back surface of the second leg member 92. The front wall 9d has a step portion 92b formed by the upper end surface 92a of the second leg member 92, and the lower end surface 9 of the first leg member 91 is formed on the back surface of the leg member 9b.
A step portion 91b is formed by 1a. Second leg 92
The length below the stepped portion 91b is made larger than the distance between the upper plate portion 11a and the lower plate portion 11b, in which the through holes 10 and 12 are formed, and the second leg member 92 connects the through hole 10 and the through hole. Sufficient to fit in both. Also, the first leg member 91 and the second leg member
An attachment hole 9c for attaching the retaining metal 13 for fixing the desktop panel 9 is formed in a connecting portion with the leg member 92.

In the above structure, the desktop panel 9 is mounted by attaching the retaining metal 13 to the leg 9b of the desktop panel 9 with the bolt 14 and then through the notch window 8a of the corner cover 8 to the leg 9b through the hole 10. Insert into 12 to perform.
In this case, in the desktop panel 9, as shown in FIG. 1, the left and right leg portions 9b are simultaneously fitted into the through holes 10 and 12 in a state where the leg portion 9b is provided on the panel portion 9a. The front surfaces of the left and right leg portions 9b are not necessarily flush with each other, and may be slightly deviated to form an angle therebetween. Alternatively, conversely, the through holes 10 and 12 formed in the fitting member 11 attached to the side panel 2 and the through holes 10 and 12 of the fitting member 11 attached to the sleeve portion 3 are formed by sheet metal working. It may not be located on the right and left horizontal lines due to error or mounting error. Even in such a case, as described above, the left and right through holes 10, 12 have a substantially central portion that is narrower than the left and right ends, so that the leg portion 9b to be fitted or the left and right through holes 10, 12 are inserted. Even if 12 is out of the normal state within the error range, the leg 9
The relative positions of b and the through holes 10 and 12 can be adjusted relative to each other around the substantially central portion of the through holes 10 and 12.
That is, when the leg portions 9b are displaced, as shown in FIG. 3B, the longitudinal center of the through holes 10 and 12 and the longitudinal center of the cross section of the leg 9b indicated by the imaginary line are aligned. Without doing so, the leg 9b can be fitted into the through holes 10 and 12 in that state.

The left and right leg portions 9b fitted in this way
As shown in FIG. 4, the step portion 91b of the leg portion 9b comes into contact with the upper surface of the side panel 2 so as not to move further downward, and the left and right through holes 10, 12 are formed.
Since it will be held by the narrow portion of the size L at the substantially central portion of the above, the horizontal movement of the desktop panel 9 is prohibited. Therefore, in order to fix the desktop panel 9 to the desk body 1, the upward movement may be prohibited. The retaining metal fitting 13 for fixing the desktop panel 9 has one end bent into an L shape engaged with the step portion 92b of the leg portion 9b, and is fixed to the leg portion 9b by the bolt 14 in this state. .. The retaining metal 13 is bent in a direction opposite to one end portion from a substantially central portion in the longitudinal direction, and a bolt 15 is inserted into a hole formed on the other end portion side.
The bolts 15 are tightened and fixed using the mounting holes 8c of the corner cover 8.

According to this desk D, the desktop panel 9
Even if the through holes 10 and 12 provided in the left and right leg portions 9b of the desk or the left and right corners on the rear end side of the desk body 1 are slightly distorted due to manufacturing errors or the like, the distortion is not corrected. A desktop panel 9 can be attached to the main body 1.
When fixing this, it is only necessary to tighten one bolt 15 from the upper side, so that the mounting work is very simple and can be performed quickly.

The present invention is not limited to the embodiment described above. For example, in the above embodiment, the through hole 1
Although the case where 0 and 12 are drilled in the upper and lower two stages has been described, only the through hole 10 may be provided. In this case, a cut-and-raised piece that abuts the lower end of the leg portion 9b may be provided on the lower plate portion 11b of the fitting member 11 so that the desktop panel 9 does not fall backward until the desktop panel 9 is fixed. Good.
Alternatively, only the through hole 10 may have the same shape as that of the above-described embodiment, and the lower through hole 12 may be a rectangular opening having a size sufficient for inserting the leg portion 9b.

In addition, the configuration of each part is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.

[0018]

As described in detail above, according to the present invention, since the substantially central portion of the through hole in the longitudinal direction is shorter than the left and right ends of the through hole, the leg portion of the desktop panel or the through hole of the desk body is formed. Even if there is some dimensional error during manufacturing in the provided part, it is possible to fit the leg part into the through hole at the same time on the left and right. If the left and right legs are fitted into the through holes when the outer dimensions of the legs are approximately the same, each of the legs will be pinched at the center of each through hole, so the desktop panel will rattle. It can be attached to the desk body without any.
