Description

Table and Chair Tripod

This invention is about a table and chair tripod, which is a supporting structure used in combination with a table or a chair.

Tables and chairs are very practical furniture in daily life. Most of their structures are combined with the table top or chair seat through the legs. Some legs are combined with the table top or chair seat by protruding an assembly structure on the legs, which is inserted into the bottom surface of the table top or chair seat and then fixed with screws or tenons.

Generally speaking, when tables and chairs are in use, the legs bear a relatively large force, especially when subjected to horizontal axial force, a shear force is formed between the legs and the table top or chair seat. The shear force acts completely on the assembly structure, causing the assembly structure to break from the legs. This is one of the reasons why the legs of current tables and chairs are not durable.

In order to provide a more durable stand, the table and chair stand of the invention includes a supporting element and a coupling element. The supporting element has a slot, which is arranged on a top surface of the supporting element. The coupling element has an insert block and a coupling block, the insert block is used to be inserted into the slot, the coupling block is located at the top end of the insert block, and the coupling block has an upper coupling surface and a lower coupling surface, the upper coupling surface is located above the coupling block and is used to couple with a table or a chair, and the lower coupling surface is located below the coupling block and is used to couple with the top surface.

Thus, since the supporting element is connected to the insert block of the joint element through the slot and then connected by welding, screws or other fixing structures, most of the shear force is absorbed by the fixing structure and does not act completely on the insert block, further reducing the risk of damage to the table and chair leg frame and improving durability.

In a preferred embodiment, the slot has a slot opening formed in a direction opposite to the top surface and one side surface of the supporting element.

In a preferred embodiment, the supporting element is made of metal, and the lower joint surface and the top surface are joined by welding.

In a preferred embodiment, the supporting element is made of wood, and the lower joint surface and the top surface are connected by a screw.

In a preferred embodiment, a plurality of supporting element screw holes are provided on the joint block, and the wood screws are used to pass through the supporting element screw holes from the upper joint surface respectively, and then the supporting element screw holes are locked into the supporting element from the top surface.

In a preferred embodiment, the table and chair leg frame further has a connecting element, which is used to connect a plurality of the connecting elements.

In a preferred embodiment, one end of the inserting blocks of the engaging elements has a side groove, and the outer side of the connecting element has a plurality of protrusions, which are used to be inserted into the side grooves.

In a preferred embodiment, the top surface and the axis of the supporting element have an angle, and the angle of the angle is not less than 90°.

Other technical contents, features and effects of the invention will be clearly presented in the following detailed description of the preferred embodiment with reference to the drawings.

As used herein, the articles "a", "an", and "any" refer to one or more than one (ie, at least one) item without specifying a specific quantity. For example, "an element" means one element or more than one element.

The invention is a table and chair stand 10. Please refer to Figure 1, which is a structural three-dimensional diagram of the table and chair stand 10.
