Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combined structure of a desk top plate and a desk wagon top plate.

[0002]

2. Description of the Related Art Conventionally, some desks have one sleeve or both sleeves fixed to the desk, but the desk body and a desk wagon (also called a side desk) provided with casters on the bottom are separate. The desk wagon is installed in Figure 8
As shown in (a), when the desk top is normally placed on the left side or the right side of the lower part of the desk and the desk top is widely used, only the top of the desk wagon is lifted and the top of the desk wagon is raised. Is used in parallel with the desk top plate.

However, as shown in FIG. 8B, the edges of the desk top plate and the side desk top plate are usually convex in cross section, so that the two desks are joined together. There is a drawback that it is difficult to use because the recess is formed in the part, and even if the desk top plate and the side desk top plate are lined up, the side desk with casters on the bottom easily moves and there is a gap between both sides. Or, Figure 1
As shown in 0, since the fixing tool (Z) for fixing the object (Y) such as a book stand placed on the desk top plate protrudes from the end surface of the desk top plate, both top plates are also fitted properly. However, there was also a drawback that it was difficult to use because it could not be joined, and a gap was created.

[0004]

Therefore, the present invention is
The present invention has been invented to eliminate these drawbacks, and is to develop and provide a connecting structure of a desk top plate and a side desk top plate that can effectively use a desk and a side desk.

[0005]

Therefore, according to the present invention, in joining a desk and a side desk, the cross-sectional shape of the edge portion of one desk top plate is formed into a convex portion, and the edge portion of the other desk top plate is formed. The cross-sectional shape of the above is formed in a concave part that fits into the convex part to facilitate the use of both top plates, and in the side desks having casters, the top plate or side part of both desks is connected by a connecting tool. A desk top plate having a vertical edge and a side desk top plate having casters with a vertical edge are connected by a connecting tool.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Next, a preferred embodiment of the present invention will be described with reference to FIG. 1. In the joining of the desk top plate (1) and the desk wagon top plate (2), one of the desks is joined. The cross-sectional shape of the edge portion (1a) of the top plate (1 or 2) is formed into a convex portion, and the cross-sectional shape of the edge portion (2a) of the other desk top plate (2 or 1) is fitted into the convex portion. By forming the recess on the top plate, the number of recessed grooves (X) formed on the joint between the two top plates is reduced and the top plate is easy to use. Consists of.

A preferred embodiment of the present invention is shown in FIG.
To explain with reference to (a) and FIG. 2 (b), in joining the desk top plate (1) and the top plate (2) of the desk wagon,
Connecting the edge portion (1a or 2a) of one top plate (1 or 2) and the edge portion (2a or 1a) of the other top plate (2 or 1) with a connecting tool (3). It is composed of a combined structure of the characteristic desk top plate and the top plate of the desk wagon.

When the connecting tool (3) is used, the cross-sectional shape of the edge (1a or 2a) of one of the desk top and the desk wagon is convex. Alternatively, the other top plate (2 or 1) may be formed such that the edge portion (2a or 1a) of the other top plate (2 or 1a) has a cross-sectional shape formed into a concave portion that fits the convex portion. Further, as shown in FIG. The edges of both top plates may be vertical.

Next, a more specific example of the connecting tool (3) is shown in FIG.
Explaining in detail based on (a) and (b), a rectangular plate (3a)
Is formed on both sides of the plate, and a protrusion strip (3b) engaged with the top plates (1) and (2) is provided on the other hand, while the desk top plate (1) and the side plate of the Zyde desk (2) are provided. Each on the back,
It has a structure in which a concave portion (3c) tightly fitted to the protrusion (3b) is bored and coupled.

Further, one specific example of the connecting tool (3) is shown in FIG.
Described in detail based on (a), (b) and (c), a rectangular plate (3a) is formed, and one or a plurality of projecting pieces (3d) are formed near both ends of the plate, respectively, On the back side of the desk top plate (1) and the zoid desk top plate (2),
A recess (3c) corresponding to the projection piece (3d) is bored,
The projection pieces (3d) are tightly fitted in the recesses (3c) and are joined together.

Further, as another specific example of the connector (3), as shown in FIGS. 6 (a) and 6 (b), a rectangular plate (3a) is formed, and a screw which can be rotated with a finger to the left and right of the plate. Providing a plurality of (4),
On the other hand, a female screw (5) screwed to the screw (4) is embedded in the back surface of each of the desk top plate (1) and the Zyde desk top plate (2).

Another specific example of the connector (3) is shown in FIG.
As shown in (a) and (b), a connecting tool (3) is formed in a hinge shape, and one of the connecting tools is fixed to the top plate (1 or 2) side with a screw, and the other of the connecting tools (3). A protrusion (3f) is provided on the other side, and a concave hole (3g) suitable for the protrusion is provided on the bottom surface of the other top plate (2 or 1) to detachably fix the two ceiling plates May be

In this case, in the case of a desk wagon having a caster at the bottom, the effect is greater.
The top plate (2) of the desk wagon may be fixed to the desk wagon or, as shown in FIG. 8, the top plate can be moved up and down.

Further, as another specific example of the connecting tool (3), as shown in FIG. 8 (a), one of the desk wagon and the desk is joined at the joining of the desk top plate and the top plate of the desk wagon. It is a female screw embedded in the side part and a connecting tool that is fixed by bolts from the inside of the other side part, and the top plate (2) and desk top plate (1) of the desk wagon do not protrude from their respective side parts. In the case, the top plate (2) of the desk wagon and the top plate (1) of the desk wagon are connected directly via a spacer (3h) when protruding from their respective sides. is there.

Further, as shown in FIG. 9, for example, by forming notches (A) on both sides near the rear end of the edge of the desk wagon top plate (2), for example, the desk top plate. Even if the fixing tool (Z) for temporarily fixing the book stand (Y) mounted on (1) and the desk top plate is projected, both top plates can be joined exactly, which is convenient for use.

[0016]

According to the present invention, the cross-sectional shape of the edge portion of one desk top plate is formed into a convex portion, and the cross-sectional shape of the edge portion of the other desk top plate is formed into a concave portion that fits into the convex portion. By doing so, there is no recess at the joint between the desk and the side desk, and it is convenient to use. Also, by temporarily connecting both desks with a connecting tool, it is easy to use and has an extremely beneficial effect. It is a thing.
