Structure connection of motion chair

Abstract

A structure connection of motion chair is disclosed for connecting a chairback to a chair base. The structure connection of motion chair consists of a pair of first supporting members and a pair of second supporting members respectively installed on both sides of the chairback, and a pair of supporting plates respectively installed on both sides of the chair base. The second supporting members are respectively located below the first supporting members, and the supporting plates are respectively corresponding to the first supporting members and the second supporting members, wherein the supporting plates are used for engaging with the first and second supporting members respectively, whereby the chairback and the chair base are connected together.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a structure connection of motion chair, and more particularly, to a chairback connection structure that can be easily dismantled and assembled. BACKGROUND OF THE INVENTION [0002] Generally, for the sake of delivery convenience, a product is commonly expected with the best possibility to be dismantled into several parts beforehand, those parts are assembled after arriving the destination, thereby reducing the space occupied by the product while being conveyed, thus saving the delivery cost. For a chair product, particularly for the chair with the functions of foot raising and inclining, such as a massage chair, a lounger or a sofa, etc., separating the chairback from the chair base is the major method for greatly reducing the product space in convey. On the other hand, since the DIY (Do It Yourself) market has been more and more popular with consumers, the function of rapidly and briefly dismantling and assembling a produ...

Benefits of technology

[0006] It is a main object of the present invention to provide a structure connection of motion chair for using the engagement of the concaved portions of the supporting plates and supporting members to lower the difficulty level of assembling the chairback and the chair base; to provide a robust and brief structural design for prolonging the usage life of the structure connection and reduce the fabrication cost.

[0011] Hence, with the application of the present invention, the difficulty level of dismantling and assembling the chairback and the chair base can be greatly lowered; a robust and brief structural design can be provided for prolonging the usage life of the structure connection and reducing the fabrication cost.

Problems solved by technology

Moreover, the structure of the fixed receiving frames 140 is quite complicated and the fabrication cost thereof is high.

Since the chair having the functions of foot raising and inclining is quite heavy in weight and large in size, it is already not easy to lift the entire chairback upwards for a certain distance, and the additional work of aligning the fixed receiving frames 140 to the rear inclining bars 120 further increase the difficulty level of the conventional technology assembling the chairback 100 and the chair base 110.
