Chair Base
A chair base including a support body and a plurality of foldable assembly legs is disclosed. The support body has a plurality of supporting legs. The plurality of foldable assembly legs is movably coupled with the foldable assembly legs.
1. Field of the Invention
The present invention generally relates to furniture and, more particularly, to a multi-sectional chair base.
2. Description of the Related Art
The modern chair base is usually formed in an integral manner in order to have strong and stable support for a chair that is mounted thereon. The chair base includes a plurality of supporting legs extending radially outwards from a center of the chair base. Thus, the supporting legs will have an axial projection area that is larger than and covers the axial projection area of the chair. As a result, the supporting legs with larger axial projection area may lead to inconvenience during disassembly, packing and transportation of the chair base.
SUMMARY OF THE INVENTIONIt is therefore the primary objective of this invention to provide a chair base allowing great convenience during disassembly, packing and transportation thereof.
The invention discloses a chair base including a support body and a plurality of foldable assembly legs. The support body has a plurality of supporting legs. The plurality of foldable assembly legs is movably coupled with the foldable assembly legs.
The present invention will become more fully understood from the detailed description given hereinafter and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
In the various figures of the drawings, the same numerals designate the same or similar parts. Furthermore, when the term “first”, “second”, “third”, “fourth”, “inner”, “outer” “top”, “bottom” and similar terms are used hereinafter, it should be understood that these terms refer only to the structure shown in the drawings as it would appear to a person viewing the drawings and are utilized only to facilitate describing the invention.
DETAILED DESCRIPTION OF THE INVENTIONAs shown in
An assembly method of the chair base is illustrated in two main steps. In a first assembly step, the support body 1 is turned over to face a bottom side of the support body 1 upwards. Then, one foldable assembly leg 2 is inserted into one supporting leg 11. Thus, the assembling protrusions 22 of the foldable assembly leg 2 may be coupled with the concave portions 112. In a second assembly step, the foldable assembly leg 2 is folded outwards by 90 degrees until the connection end 21 is fully received in the assembling groove 111. Therefore, the support body 1 and the foldable assembly leg 2 will appear as the streamlined shape. So far, one foldable assembly leg 2 is assembled to the support body 1. Other foldable assembly legs 2 may be assembled in the same manner as described in the first and second steps above.
Besides, the assembling protrusion 22 of the foldable assembly leg 2 has a round shape. The foldable assembly legs 2 may be coupled with the support body 1 in other manners, such as via a hinge or sliding track.
In the invention, the support body 1 is allowed to have a smaller axial projection area when the foldable assembly legs 2 are not assembled with the support body 1. Thus, easy assembly, packing and transportation of the chair base are achieved.
Although the invention has been described in detail with reference to its presently preferable embodiment, it will be understood by one of ordinary skill in the art that various modifications can be made without departing from the spirit and the scope of the invention, as set forth in the appended claims.
Claims
1. A chair base, comprising:
- a support body having a plurality of supporting legs; and
- a plurality of foldable assembly legs movably coupled with the supporting legs.
2. The chair base as claimed in claim 1, wherein each of the plurality of foldable assembly legs has a connection end and two assembling protrusions located on two sides of the connection end.
3. The chair base as claimed in claim 2, wherein each of the plurality of supporting legs has an assembling groove for receiving the connection end, and two concave portions for respectively receiving the two assembling protrusions.
4. The chair base as claimed in claim 3, wherein the connection end has an outer diameter equal to an inner diameter of the assembling groove.
5. The chair base as claimed in claim 3, wherein each of the two assembling protrusions has a diameter smaller than that of each of the two concave portions.
6. The chair base as claimed in claim 1, wherein each of the plurality of foldable assembly legs consists of a plurality of parts capable of mutual movement.
7. The chair base as claimed in claim 2, wherein the two assembling protrusions are in a round shape.
8. The chair base as claimed in claim 2, wherein the two assembling protrusions are in a round shape with a cutoff edge.
