Canopy

Abstract

A canopy includes a plurality of height-adjustable support frames including upper and lower frames; a bottom fixture inserted/fixed in each lower frame; a fixed two-point connection member fixed to each upper frame; a height-adjustable movable two-point connection member installed to each upper frame; three-point connection members positioned between the upper frames respectively; upper and lower four-point connection members positioned in the middle of the support frames respectively and having a vertically-installed anti-drooping frame; and pivoting frames whose both ends are connected to each connection member and whose center portion is hinged pivotally. Each pivoting frame has a insert group protruded on both ends of the pivoting frame at interval to prepare a vertical receiving groove. Each connection member has supports inserted into the insert groove, and an insert groove is formed in the supports to insert one of the inserts therein.

1 . A canopy, comprising: 
 a plurality of support frames, each including an upper frame and a lower frame so that the lower frame is inserted into the upper frame to be capable of adjusting a height by means of a height adjustment member;    a bottom fixture inserted and fixed in a lower portion of each lower frame;    a fixed two-point connection member fixed to an upper portion of each upper frame;    a movable two-point connection member installed to an outer circumference of each upper frame and having a height adjustment member;    a plurality of three-point connection members positioned between the upper frames respectively;    upper and lower four-point connection members positioned at a middle position between the support frames respectively and having an anti-drooping frame vertically installed thereto; and    a plurality of pivoting frames whose one end and the other end are connected to each connection member and whose center portion is hinged to be pivotable with respect to each other,    wherein each pivoting frame has a group of inserts protrusively formed in both ends of the pivoting frame with a predetermined interval to prepare a receiving groove vertically perforated therein,    wherein each connection member has a plurality of supports inserted into the insert groove of the pivoting frame, and an insert groove is formed in the supports so that one of the inserts of the pivoting frame is inserted therein.    
   
   
       2 . The canopy according to  claim 1 , 
 wherein through holes are perforated in the insert of each pivoting frame and the support of each connection member at corresponding positions for fixing a pin, and a reinforcing member is interposed in each insert and each receiving groove of the pivoting frame.    
   
   
       3 . The canopy according to  claim 2 , 
 wherein the reinforcing member is installed to surround each insert, and insert holes corresponding to the through hole of each insert are prepared in both ends of the reinforcing member.    
   
   
       4 . The canopy according to  claim 1 , wherein the bottom fixture includes: 
 a fixed protrusion inserted into an inner circumference of the lower frame;    a position adjustment bolt vertically screwed to the fixed protrusion;    a movable part screwed to the position adjustment bolt so as to be positioned in an upper portion of the fixed protrusion; and    a fixed part interposed between the fixed protrusion and the movable part.    
   
   
       5 . The canopy according to  claim 4 , 
 wherein the movable part is configured to have a width smaller than an inner diameter of the lower frame, and the fixed part is configured to have a width greater than an inner diameter of the lower frame.
