Spherical chair structure

Abstract

A spherical chair structure includes: a chair frame having a seat frame and an arc containing space in the seat frame; a cushion installed on the seat frame and including a spherical mat, and the bottom of the spherical mat being contained in the containing space, and the spherical mat being protruded from the seat frame to form a seat pad; and a positioning device having a plurality of binder for surrounding and positioning the spherical mat, and an end of the binder being fixed to the chair frame, so that the spherical chair can be used as a chair and a fitness equipment safely and comfortably to provide excellent leisure and fitness exercises. The spherical chair structure can be packed with less packaging material and transportation space to achieve the effects of reducing the transportation cost and protecting our environment.

What is claimed is: 
     
         1 . A spherical chair structure, comprising:
 a chair frame, including a seat frame, and the seat frame having an arc containing space;   a cushion, installed on the seat frame, and including a spherical mat, and the bottom of the spherical mat being contained in the containing space, and the spherical mat being upwardly protruded out of the seat frame to form a seat pad; and   a positioning device, including a plurality of binders surrounding and positioning the spherical mat, and an end of each binder being fixed to the chair frame.   
     
     
         2 . The spherical chair structure of  claim 1 , wherein the seat frame is substantially an arc frame having a plurality of legs coupled to the seat frame. 
     
     
         3 . The spherical chair structure of  claim 2 , wherein the leg includes a leg body and a foot coupled to each other, and the foot has a fixing portion. 
     
     
         4 . The spherical chair structure of  claim 3 , wherein the leg is formed by bending a rod and the fixing portion is a rod coupled between both sides of the foot. 
     
     
         5 . The spherical chair structure of  claim 1 , wherein the spherical mat is substantially a hollow sphere. 
     
     
         6 . The spherical chair structure of  claim 3 , wherein the binder has a fastener installed at an end fixed to the chair frame, and the fastener is fixed to the fixing portion of the leg. 
     
     
         7 . The spherical chair structure of  claim 6 , wherein the fastener is a buckle. 
     
     
         8 . The spherical chair structure of  claim 3 , wherein the binder has an end fixed to the chair frame and surrounded and fixed to the fixing portion of the leg, and the binder has an inner fixing strip and an outer fixing strip at the surrounded and fixed end of the binder, and a fixing element is installed separately at opposite fixing surfaces of the inner fixing strip and the outer fixing strip. 
     
     
         9 . The spherical chair structure of  claim 8 , wherein the fixing element is an adhesive tape or a latch module. 
     
     
         10 . The spherical chair structure of  claim 1 , wherein the plural binders form an overlapped and attached fixing area on the spherical mat. 
     
     
         11 . The spherical chair structure of  claim 1 , wherein the plural binders are at least two binder bodies surrounded and installed to the spherical mat. 
     
     
         12 . The spherical chair structure of  claim 1 , wherein the binders preferably have a stretching elasticity.
