Structure connection of motion chair
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.
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 INVENTIONGenerally, 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 product has become one of the important factors determining the product competition. Often, the consumers need to separate the chairback from the chair base so as to perform certain necessary maintenance work. Hence, how to rapidly and briefly dismantle and assemble the chairback and the chair base is quite an important topic for the chair industry.
Referring to
However, the aforementioned conventional technology relies on the elasticity of the retaining spring plates 130 and the engagement of the retaining spring plates 130 and the retaining portions 122, to connect the chairback 100 to the chair base 110, and then the rear inclining bars 120 are secured by the structure of the fixed receiving frames 140, so that the life of the fixed receiving frames 140 are frequently shortened due to the elastic fatigue thereof. Moreover, the structure of the fixed receiving frames 140 is quite complicated and the fabrication cost thereof is high. After several times of usage, the fixed receiving frames 140 are easily to be deformed and cannot be used any more. On the other hand, with the application of the conventional technology, the chairback 100 has to be lifted upwards for quite a distance while being assembled with the chair base 110, and thus the assembly of the chairback 100 and the chair base 110 cannot be completed smoothly until the fixed receiving frames 140 are aligned to the rear inclining bars 120. 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.
Hence, there is a need to develop a structure connection of motion chair for lowering the difficulty level of dismantling and assembling the chairback and the chair base; for providing a robust and brief structural design to prolong the usage life of the structure connection and reduce the fabrication cost, thereby overcoming the disadvantage of the conventional structure connection of motion chair.
SUMMARY OF THE INVENTIONIt 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.
According to the aforementioned object, the present invention provides a structure connection of motion chair used for connecting a chairback to a chair base.
According to a preferred embodiment of the present invention, the structure connection of motion chair comprises: a pair of first supporting members respectively installed on both sides of the chairback, 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, wherein the first supporting members are located on the positions near the chair base, and the second supporting members are located below the first supporting members, and the supporting plates are respectively corresponding to and engaged with the first supporting members and the second supporting members.
Further, each of the supporting plates comprises: a first supporting plate component and a second supporting plate component connected to the first supporting plate component, wherein the first supporting plate component has at least one locking hole for being fixed to the chair base. There is an angle between a first side of the second supporting plate component and the first supporting plate component, wherein the angle is greater than 0 degrees and smaller than 180 degrees. Further, the second supporting plate component has a first concaved portion and a second concaved portion, wherein the first concaved portion is located on one end opposite to a connection side between the first supporting plate component and the second supporting plate component, and the first concaved portion is used for supporting the first supporting member. The second concaved portion is located on the position of a second side near the connection side, wherein the second side is opposite to the first side, and the second supporting member can be engaged with the second concaved portion so as to sustain the supporting plate.
Further, each of the second supporting plate component has a locking hole for being fixed to the chairback by using a fixing element.
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.
BRIEF DESCRIPTION OF THE DRAWINGSThe foregoing aspects and many of the attendant 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, wherein:
