Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tabletop structure. The table top structure of the present invention is applicable to appropriate tables such as a table, a dining table, a kotatsu, a desk, and the like.

[0002]

2. Description of the Related Art Tables require a small floor space for installing the tables if the tabletop area is small, but many objects cannot be placed on the tabletop, and conversely if the tabletop area is large. Although it can store things, it requires a large floor space.

By the way, in conventional tables, the auxiliary base plate is stored in the lower surface side of the top plate so that it can be freely taken in and out, and the auxiliary base plate is stored on the lower surface side of the top plate, and the auxiliary base plate is placed on the top surface. There is a table with an auxiliary base plate that can be used in two forms with the plate being pulled outward from the bottom surface.

[0004]

However, in this kind of table with an auxiliary base plate, usually four support legs are provided below the top plate, and the auxiliary base plate is provided on the lower surface side of the top plate. When provided, the area of the auxiliary base plate is limited by each support leg. That is, when the auxiliary base plate is provided on the lower surface side of the top plate, it is necessary to make the width of the auxiliary base plate smaller than the distance between the two support legs located on the pull-out side. in this way,
In the conventional tables with an auxiliary base plate, the area of the auxiliary base plate needs to be smaller than the area of the table top plate, and when the auxiliary base plate is pulled out, the top plate and the auxiliary base plate have a step difference in plan view. Has occurred (the width is different), and there is a problem that the appearance becomes poor.

Further, the structure in which the auxiliary base plate is put in and taken out on the lower surface side of the top plate as described above cannot be applied when there is an obstacle on the lower surface of the top plate, such as an electric pouch or a desk with a drawer. There are also problems.

In view of the above-mentioned conventional problems, the present invention provides a table having a movable plate which can be freely taken in and out, without the size and shape of the movable plate being restricted by the supporting legs of the table. It is an object of the present invention to allow the user to freely design, and to be able to provide the movable plate without trouble even if there is an obstacle on the lower surface of the table top plate.

14 is provided, and the guide rails 51 and 51 of the guide devices 5 and 5 on the upper plate 2 side are engaged with the protrusions 14 and 14, respectively. The engagement structure between the guide devices 5 and 5 and the protrusions 14 and 14 is similar to that of the first embodiment. Each of the guide devices 5 and 5 has a length of, for example, about 70 to 80 cm, so that the upper plate 2 can be extended to a greatly extended position indicated by reference numeral 2 ″. In the fourth embodiment, the auxiliary leg 6 is provided on the lower surface of the upper plate 2 close to the projecting side, and the fourth embodiment corresponds to the configuration of claim 2 of the present application.

In addition, the tabletop structure of the present invention can employ an appropriate table such as a dining table, an office desk, and a conference table in addition to the above-mentioned table and table as the table.

[0029]

The table-top structure of the present invention has the following effects. First, since the upper plate 2 of the double top plate 1 can be horizontally rotated or slid on the lower plate 3, the auxiliary base plate can be put in and taken out under the top plate as in the conventional case. Thus, there is no limitation on the shape or size of the movable side plate (upper plate 2). Therefore, there is an effect that the movable side plate (upper plate 2) can be made to have a larger area than that of the conventional lower drawer type and the usable area can be increased. or,
The upper plate 2 and the lower plate 3 can have the same shape and the same size,
In that case, there is also an effect that the appearance does not deteriorate in both the polymerized state and the bulged state.

Further, in the case where the upper plate 2 is allowed to be superposed and extended on the lower plate 3, the upper plate 2 becomes unstable when the upper plate 2 is greatly extended. By storing the auxiliary leg 6 on the lower surface, the upper leg 2 can be supported by the auxiliary leg 6 when the upper plate 2 is greatly extended. Further, since the auxiliary leg 6 does not project downward from the lower surface of the upper plate 2 in the stored state, when the upper plate 2 is superposed on the lower plate 3, or when the upper plate 2 is moved on the lower plate 3, etc. There is no problem.
