Chair assembly

Abstract

A chair assembly has a seat set, two front multi-connectors, two rear multi-connectors, two front leg members and two rear leg members. The seat set has two transverse bars and two longitudinal bars. Each of the front and rear multi-connectors is mounted between adjacent transverse bar and longitudinal bar. The front leg members are mounted respectively on the front multi-connectors. The rear leg members are mounted respectively on the rear multi-connectors. The front multi-connectors and the rear multi-connectors connect the seat set, the front leg members and the rear leg members together without forming tenons and mortises on the front and rear leg members, which simplifies manufacturing process of the chair assembly.

What is claimed is: 
     
         1 . A chair assembly comprising:
 a seat set having two opposite transverse frame bars and two opposite longitudinal frame bars arranged in a rectangle;   a pair of front multi-connectors and a pair of rear multi-connectors, each of the front multi-connectors and the rear multi-connectors mounted between and connecting adjacent transverse frame bar and longitudinal frame bar;   two front leg members mounted respectively on the front multi-connectors, and each front leg member having
 a front leg bar; and 
 a handlebar formed integrally on and protruding upward from an end of the front leg bar; and 
   two rear leg members mounted respectively on the rear multi-connectors, and each rear leg member having
 a rear leg bar; and 
 a backrest sidebar formed integrally on and protruding upward from the rear leg bar. 
   
     
     
         2 . The chair assembly as claimed in  claim 1  further comprising two assembling members and each assembling member connecting one of the handlebars and one of the backrest sidebars. 
     
     
         3 . The chair assembly as claimed in  claim 2 , wherein each of the front multi-connectors and the rear multi-connectors has
 a longitudinal sleeve having a longitudinal mounting hole defined in the longitudinal sleeve and mounted around one of the longitudinal frame bars;   a transverse sleeve mounted securely on the longitudinal sleeve and having a transverse mounting hole defined in the transverse sleeve and mounted around one of the transverse frame bars; and   a vertical sleeve mounted securely on the transverse sleeve and having a vertical mounting hole defined through the vertical sleeve.   
     
     
         4 . The chair assembly as claimed in  claim 3 , wherein the longitudinal mounting hole, the transverse mounting hole and the vertical mounting hole of each of the front multi-connectors and the rear multi-connectors are oriented in different directions. 
     
     
         5 . The chair assembly as claimed in  claim 4 , wherein each assembling member has
 a first sleeve having a first mounting hole defined through the first sleeve and mounted around the handlebar of one of the front leg members; and   a second sleeve mounted securely on the first sleeve and having a second mounting hole defined through the second sleeve and mounted around one of the backrest sidebars.   
     
     
         6 . The chair assembly as claimed in  claim 5 , wherein the first mounting hole and the second mounting hole of each assembling member are oriented in different directions. 
     
     
         7 . The chair assembly as claimed in  claim 6 , wherein
 each backrest sidebar has multiple assembling holes defined in an inside surface of the backrest sidebar; and   multiple supporting crossbars are mounted between the backrest sidebars of the rear leg members and correspond to the assembling holes of each backrest sidebar, and each supporting crossbar has two ends mounted respectively in two corresponding assembling holes of the backrest sidebar.
