FORMING STRUCTURE OF ARMREST AND CHAIR-LEG FOR BAMBOO CHAIR
A forming structure of the armrest and the chair-leg for a bamboo chair comprising the armrest and the chair-leg with a general -shape formed by bending the bamboo material, which the height of the armrest is higher than the height of the chair-leg. Two opposite outer surfaces of the chair-leg are adjoined with two opposite inner surfaces of the armrest to form a one-body armrest-leg unit. The bamboo chair is formed by combining a plurality of bamboo-seat units between two armrest-leg units to increase the load-bearing strength and enhance the one-body look-and-feel.
a) Field of the Invention
The present invention relates to a bamboo chair made of the bamboo material, and more particularly, to the structure which combines the armrest and chair-leg into one-body by using the bamboo material to increase the load-bearing strength and enhance the one-body look-and-feel of the bamboo chair.
b) Description of the Prior Art
Normally, the material adopted for the chair includes many kinds, such as wood, plastic, metal, and leather, etc. Besides the practical function; the chair has the decoration effect owing to its delicate manufacturing and graceful appearance. Moreover, the chair made of bamboo or wood material is adored by the antique lover because of its primitive character.
In general, the structure of the chair includes a bottom portion; a support portion; and a seat portion no matter what material of the chair is made. The bottom portion is used to touch the ground, and the seat portion is used to provide for the hip of the user to sit. The support portion is connected between the bottom portion and the seat portion to support the seat portion. However, the weaving and knitting fabrication method is adopted for nearly all the conventional bamboo chair so as to make the bamboo chair be lack of elasticity after being formed. It will easily make the user feel uncomfortable after a long-time sitting.
SUMMARY OF THE INVENTIONThe object of the present invention is to provide a kind of structure for the bamboo chair that ingeniously connects and combines the armrest with the chair-leg into a one-body, so as to increase the whole strength of the bamboo chair and make its look-and-feel more delicate.
One feature of the present invention is bending the bamboo material in advance to form the armrest and the chair-leg with a general -shape, and the height of the armrest is higher than the height of the chair-leg.
Furthermore, the side surface of the chair-leg is set with a plurality of concave holes, and the seat is set with a plurality of lateral bamboo strips in the present invention. Two ends of the lateral bamboo strip are respectively matched into the concave holes of the chair-leg.
The lateral bamboo rods of the present invention are fixed to the chair-leg by using the fixing elements after inserting the lateral bamboo rods into the concave holes of the chair-leg, and so as to avoid the separation between the seat and the chair-leg because of the bearing weight.
The chair-leg and the armrest made of bamboo material of the present invention have two legs and two armrest-legs respectively, and the two legs tilt an angle toward the leaving direction for each other. The two armrest-legs also tilt an angle toward the leaving direction for each other.
The technical measure of the present invention to construct the seat is utilizing a plurality of lateral bamboo strips to form a continuous bended shape, and laminating the first bamboo seat-component and the second bamboo seat-component in parallel pairs to construct a seat unit. A plurality of lateral bamboo rods are set between the first bamboo seat-component and the second bamboo seat-component, and two ends of the lateral bamboo rods are respectively protruded out of two sides of the seat for a proper length. The first bamboo seat-component and the second bamboo seat-component of the seat unit are separated out laminated space by using the lateral bamboo rods. Therefore, the bamboo seat with the bamboo chair-back is constructed by nailing each first bamboo seat-component and each second bamboo seat-component with the lateral bamboo rods.
The present invention utilizes good elasticity feature of the bamboo material and crafted technical art to further combine the bamboo armrest with the bamboo chair-leg into a one-body structure, so as to increase the whole strength of the bamboo chair and make its look-and-feel more delicate. Therefore, the present invention with excellent performance and practical application is new and innovative. Consequently, the present invention satisfies all the requirements of the patent law.
The detailed explanation of the present invention is described as following. The described preferred embodiments are presented for purposes of illustrations and description, and they are not intended to limit the scope of the present invention.
The foregoing aspects and many of the accompanying objects, functions, and advantages of this invention will become more readily appreciated as the same becomes better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings.
Firstly, please refer to
Next, the chair-leg 1 of the present invention is formed by bending the bamboo material to have a general -shape as shown in
Then, the structure of the armrest 2 for the present invention is also formed by bending the bamboo material to have a general -shape as shown in
Through the structure of the chair-leg 1 and the armrest 2 described above, the implemented way of the present invention for combining the chair-leg 1 with the armrest 2 into a one-body is to combine the two opposite outer surfaces of the legs 11 and the two opposite inner surfaces of the armrest-legs 21 so as to form a one-body armrest-leg unit.
Furthermore, as shown in
The assembly way of the seat 3 with two armrest-leg units is direct inserting the lateral bamboo rods 4 positioned in two sides of the seat 3 into the concave holes 13 of the chair-leg 1 and fixing them. Preferably, the tight fastening is applied between the two ends of the lateral bamboo rods 4 and the concave holes 13. Moreover, the lateral bamboo rods 4 may be further drilled holes in the proper positions near their free ends. And, the inner surfaces of the chair-leg 1 may be drilled corresponding holes in the proper positions to make the corresponding holes correspond to each other after the lateral bamboo rods 4 entering into the concave holes 13. Then, the complete fixing between the lateral bamboo rods 4 and the chair-leg 1 is obtained by using the fixing elements 5 to nail into the corresponding holes. Accordingly, the better load-bearing strength and the one-body look-and-feel are achieved by the present invention.
The foregoing descriptions of specific embodiments of the present invention have been presented for purposes of illustrations and description. They are not intended to be exclusive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and its practical application, to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to particular use contemplated. It is intended that the scope of the invention be defined by the Claims appended hereto and their equivalents.
