Trampoline frame with inward-pointing support feet and trampoline employing such frame

Abstract

A trampoline frame includes a horizontally disposed side frame and multiple support legs joined to the side frame. Each support leg includes a vertical main section and a bent section which bends and extends from a lower end of the vertical main section. The bent section includes a support section configured to contact a ground, and is located on a side of a projection of the side frame on the ground that is closer to a center of the trampoline frame. By providing such bent section for each support leg, the trampoline frame structure can prevent the support legs from shifting toward the outside after long term use, thereby significantly improving the support strength of the trampoline frame and prolonging its service life.

1 . A trampoline frame, comprising:
 a horizontally disposed side frame; and   a plurality of support legs joined to the side frame,   wherein each support leg includes a vertical main section and a bent section which bends and extends from a lower end of the vertical main section, the bent section including a support section configured to contact a ground, wherein the support section is located on a side of a projection of the side frame on the ground that is closer to a center of the trampoline frame.   
     
     
         2 . The trampoline frame of  claim 1 , wherein the vertical main section and the support section are perpendicular to each other, and the support section points to the center of the trampoline frame. 
     
     
         3 . The trampoline frame of  claim 1 , wherein the side frame includes a plurality of side frame tube sections, wherein each two adjacent side frame tube sections and one support leg are connected together by a two-ended corrector or a three-ended connector. 
     
     
         4 . The trampoline frame of  claim 3 , wherein
 either: each of the plurality of side frame tube sections is arc shaped and the plurality of side frame tube sections are arranged to collectively form a round side frame;   or: each of the plurality of side frame tube sections is straight and the plurality of side frame tube sections are arranged to collectively form a polygonal side frame.   
     
     
         5 . The trampoline frame of  claim 3 , wherein the plurality of side frame tube sections and the plurality of support legs are each formed of a round tube or a D shaped tube or a square tube. 
     
     
         6 . The trampoline frame of  claim 1 , wherein the side frame includes a plurality of side frame tube sections, wherein each two adjacent side frame tube sections are connected together by a connecting member, and the trampoline frame further comprising a plurality of downwardly pointing connecting tubes each being welded onto one of the side frame tube sections. 
     
     
         7 . The trampoline frame of  claim 6 , wherein
 either: each of the plurality of side frame tube sections is arc shaped and the plurality of side frame tube sections are arranged to collectively form a round side frame;   or: each of the plurality of side frame tube sections is straight and the plurality of side frame tube sections are arranged to collectively form a polygonal side frame.   
     
     
         8 . The trampoline frame of  claim 6 , wherein the plurality of side frame tube sections and the plurality of support legs are each formed of a round tube or a D shaped tube or a square tube. 
     
     
         9 . The trampoline frame of  claim 6 , wherein each connecting tube is connected to one of the plurality of support legs by interference fitting. 
     
     
         10 . The trampoline frame of  claim 1 , wherein the side frame includes a plurality of side frame tube sections, each side frame tube section including a horizontally disposed main section and two downwardly bent sections that respectively extend from two ends of the main section, wherein two bent sections of two adjacent side frame tube sections are compressed into half-circles in cross-sectional shape with a support leg disposed between them, and wherein the two compressed bent sections and the support leg are affixed to each other by fasteners. 
     
     
         11 . The trampoline frame of  claim 10 , wherein
 either: each of the plurality of side frame tube sections is arc shaped and the plurality of side frame tube sections are arranged to collectively form a round side frame;   or: each of the plurality of side frame tube sections is straight and the plurality of side frame tube sections are arranged to collectively form a polygonal side frame.   
     
     
         12 . The trampoline frame of  claim 10 , wherein the plurality of side frame tube sections and the plurality of support legs are each formed of a round tube or a D shaped tube or a square tube.
