Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improvement of a table, and more particularly to a table in which support legs are radially attached to the lower end of a column provided on a top plate.

[Conventional technology]

Conventionally, various types of tables have been provided in which the support legs are radially provided on the lower end of the support column installed on the top plate, but steel support columns and support legs are integrally formed by welding, or wooden support columns and support legs. Most of them are bonded and integrally formed,
Although integrally formed, the strength is increased, but it is bulky and has a drawback that the storage and transportation costs are high. In addition, in order to be able to assemble the support leg at the same time as fixing the support column to the top plate at the place of use, we also provide through holes and screw holes in the base of the support leg and the bottom end of the support column, and fix them with screws. However, there are problems such as loosening of screws and stress in the direction of twisting the supporting leg, which causes rattling at the connecting portion between the support column and the supporting leg.

[Problems to be solved by the device]

In view of the above situation, the present invention intends to solve the problem by forming the top plate, the column and the supporting leg separately, and easily and firmly connecting and fixing them at the place of use, which reduces storage and transportation costs. The point is to provide a table that can.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention has a top plate and a base plate for suspending and fixing it on the lower surface of the top plate, and an even number of recesses having a substantially T-shaped cross section along the entire length in the outer peripheral length direction. Struts provided at equal intervals, a support leg formed by projecting two projecting ridges having a substantially T-shaped cross section into the base, which slide-fit into the adjacent two ridges at the same time, and two adjacent ridges. And a long connecting member formed by projecting two projecting strips each having a substantially T-shaped cross section, which are slidably fitted to each other simultaneously, and are connected from below to a recessed strip of a column fixedly mounted on the lower surface of the top plate. Fit the ridges of the members, then the ridges of the supporting legs, and with the upper and lower ends of the connecting member joined to the substrate and the base, respectively, fix the base to the lower end of the column with a fixing screw. Then, a table is constructed by radially arranging a plurality of supporting legs and fixing them to a support.

[Action]

According to the table of the present invention having the above-mentioned contents, the convex ridges of the connecting member are slidably fitted from below to the two adjacent concave ridges having a substantially T-shaped cross section, which are provided on the outer periphery of the pillar fixedly mounted on the lower surface of the top plate. Then, the convex strips of the supporting leg are slidably fitted to each other, and the upper and lower ends of the connecting member are joined to the substrate and the base, respectively, and the base is fixed to the lower end of the column with a fixing screw so that the column is fixed to the column. While controlling the twist of the supporting leg,
Upward movement of the supporting leg is completely regulated through the connecting member, and fixing is performed by fixing screws so that the supporting leg is prevented from slipping downward and is fixed.
Since the convex stripes are fitted to the adjacent concave stripes,
It is possible to radially attach a plurality of support legs to the lower end of the column at an equal angle.

Struts provided at equal intervals, a support leg formed by projecting two projecting ridges having a substantially T-shaped cross section into the base, which slide-fit into the adjacent two ridges at the same time, and two adjacent ridges. And a long connecting member formed by projecting two ridges having a substantially T-shaped cross section, which are slidably fitted to each other simultaneously,
The convex strips of the connecting member are fitted from below to the concave strips of the columns fixedly fixed to the lower surface of the top plate, and then the convex strips of the supporting legs are fitted, and the upper and lower ends of the connecting member are joined to the substrate and the base, respectively. In this state, the base is detachably fixed to the lower end of the column with a fixing screw, and a plurality of supporting legs are radially fixed to the column, so that each member can be stored and transported in a divided state. Therefore, the storage and transportation costs can be reduced, and when assembling, after the pillar is fixedly mounted on the lower surface of the top plate, two adjacent ridges having a substantially T-shaped cross section provided on the outer periphery of the pillar are provided. Then, the projection of the connecting member is slid from below, then the projection of the supporting leg is slid and fitted, and the upper and lower ends of the connecting member are joined to the substrate and the base, respectively, and the base is attached to the lower end of the column. Removably fixed with fixing screws, extremely easy to assemble In addition, the mounting direction of the supporting leg to the column can be set appropriately by selecting two adjacent recessed ridges, and the supporting leg can be mounted radially. Since the two convex shapes are slid into the two concave lines of the column, 2
The support of the point prevents the supporting leg from being twisted with respect to the support column, and furthermore, the upward movement of the supporting support leg can be completely regulated via the connecting member. It does not slip out and can be firmly attached. Further, when disassembling, the fixing screw can be removed and the supporting leg and the connecting member can be simply pulled out from the column.

Further, in the case where one column is provided on the top plate, at least three or more supporting legs can be radially connected to be self-standing, and two columns are provided on the lower surface of the top plate with a space therebetween. In this case, it suffices to attach two support legs linearly to each support, and according to the present invention, various types of tables can be constructed using the support and support legs having the same structure.
