Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is an arc-shaped ceiling member formed by a common relationship with the basic constituent members such as leg members The present invention relates to an extension table that includes a plate and a polygonal top plate so that the extension table can be extended into various planar shapes.

[Conventional technology]

Conventionally, a table or desk which can be extended by connecting a rectangular top plate, or a rectangular top plate is butt-connected with a semi-circular top plate or a triangular top plate for extension. Tables and desks are well known.

However, there is no table or the like having a circular top plate or a table in which desks are connected and extended.

One circular top plate is used not only for other top plates of the same circular shape but also for other top plates of a planar shape with their outer peripheral edges being in contact with each other for a predetermined length. This is because they cannot come into contact with each other.

[Problems to be solved by the device]

However, even if it is a top plate that has an arc-shaped outer peripheral edge, if it can be joined and extended, it has a wide variety of extension shapes and more space than individual tables that are laid out in various shapes. A highly efficient table can be formed, which is practically convenient.

In view of such a point, the present invention has an object to develop a table which can be extended in various plane shapes even with a top plate having a substantially circular or arc-shaped outer peripheral edge.

[Means for Solving the Problems]

The structure of the present invention made in order to solve the above-mentioned problems is that two types of arc-shaped top plates having the same radius and a central angle of 120 degrees and 180 degrees are formed, and both sides in the length direction. The angle is 30 degrees, 60 degrees, 90 degrees, 120 degrees, or 180 degrees, and two sides sandwiching this angle are formed at least at the sides having the same length as the radius of the top plate, and as a whole, a triangle or A rectangular top plate having an arbitrary polygonal shape, and a leg member having a diameter that fits within the diameter of the arc-shaped top plate, and the support portions of the respective top plates are radially formed on the upper portion thereof at a pitch of 60 degrees. A leg member, and the square top plate is mounted on the top plate supporting portions of two or more leg members on both sides thereof, and the arc-shaped top plate is attached to the remaining top plate supporting portions of the leg members. Characterized by being able to freely extend the top plate in a plane by mounting it on a rack A.

[Action]

A circular top plate is formed on a split type arc top plate with central angles of 180 ° and 120 ° respectively, and a polygonal top plate is formed on both sides with an angle of 30 ° or 60 °. By forming the sides sandwiching the same length as the radius of the arc-shaped top plate, for example, two sets of the two arc-shaped top plates with the central angles of 120 degrees and 180 degrees are each formed into one leg member. By mounting and supporting the top plate on one side of the polygonal top plate by one leg member, the square top plate is erected and supported between the two leg members, and is substantially above the leg members. A table is formed which has a top plate shape in which a circular top plate is located, that is, the top plate is extended.

Even if three leg members are positioned at the apexes of a triangle and each leg member is supported by an arc-shaped top plate of 120 degrees and 180 degrees, a polygonal top plate is erected and supported between each leg member. By doing so, one table having a top plate shape extended and supported by being installed between the three leg members is formed.

Can be achieved.

This point is that the central angle of the arc-shaped top plates 1 and 2 is 120 in the above embodiment.
Except for the case of 180 degrees, the above is performed using an arc top plate with a central angle formed to an integral multiple of 60 degrees, that is, an arc top plate with a center angle of 60 degrees and 240 degrees (not shown). Similar to the example, the top plate can be extended in various directions.

In the above embodiment, if two top plates 1 having a central angle of 120 degrees are used for the arc-shaped top plate of one leg member 4, the angles on both sides of the square top plate 3 will be 120 degrees.

Similarly, when one arc-shaped top plate 2 having a central angle of 180 degrees is used, both sides of the square top plate 3 have an angle of 90 degrees or 180 degrees.
