Simply-Assembled Bath Chair

Abstract

A simply assembled bath chair includes a seat, a backrest, two backrest support racks, and four chair legs. The seat has a bottom surface provided with two tube frames inserted by the chair legs, and four fixing bases inserted by the backrest support racks of the backrest. The connecting ends of the tube frames and the chair legs are correspondingly formed with a conical portion. Each of the connecting ends of the tube frames is sleeved with a first screwing member, while each of the connecting ends of the chair legs is sleeved with a second screwing member correspondingly screwed to the first screwing member. After the connecting ends of the tube frames and the chair legs are connected to each other, the second screwing member of the chair legs is screwed to the first screwing member of the tube frames, so that the chair legs are moved upward by the second screwing member. As a result, the connecting ends of the tube frames and the chair legs can be tightly matched with each other, so as to stabilize the support of the chair legs without any loosening or risk of shaking. When the seat, the backrest, the backrest support racks, and the chair legs are detached from and stacked with each other, the storage and transportation cost of the bath chair can be substantially reduced.

1 . A simply-assembled bath chair, comprising of:
 a seat having a bottom surface provided with two crossed tube frames  11  fixed thereon, wherein each of the tube frames has two ends bent downward and defined as two connecting ends, while each of the connecting ends is sleeved with a first screwing member;   a backrest; and   four chair legs, each of which has an upper end defined as a connecting end correspondingly connected to each of the connecting ends of the tube frames, wherein each of the connecting ends of the chair legs is sleeved with a second screwing member correspondingly screwed to the first screwing member, while each of the connecting ends of the chair legs is formed with a conical portion corresponding to a conical portion formed on each of the connecting ends of the tube frames.   
   
   
       2 . The simply-assembled bath chair of  claim 1 , wherein each of the connecting ends of the tube frames is formed with a concave positioning portion, while each of the corresponding connecting ends of the connecting ends of the chair legs is formed with a convex positioning portion which is engaged with the concave positioning portion. 
   
   
       3 . The simply-assembled bath chair of  claim 1  wherein each of the two tube frames on the bottom surface of the seat has a front section and a back section, each of which is correspondingly provided with a fixing base for a lower end of each of backrest support racks of the backrest to insert thereto. 
   
   
       4 . The simply-assembled bath chair of  claim 1 , wherein two sides of a lower edge of the backrest is formed with two through holes for each of the backrest support racks of the backrest to insert thereto. 
   
   
       5 . The simply assembled bath chair of  claim 1 , wherein each of the chair legs comprises a leg tube and a retractable tube, wherein the leg tube can be inserted into the retractable tube and retractably positioned in relation to the retractable tube, the second screwing member is sleeved on the connecting end defined by an upper end of the leg tube, and the conical portion of the connecting end has an average outer diameter greater than an inner diameter of a bore of the second screwing member, which the leg tube can pass through.
