Adjustable jump bar stand

Abstract

An adjustable jump bar stand for skaters, skateboarders and the like includes an elongated post, a base for receiving a lower end segment of the post so that the post is supported vertically and an elongated jump bar having an end swivelly and adjustably connected to the post so that the jump bar extends out horizontally from the post at a variable elevation thereon and can swivel about the post. The jump bar provides an obstacle over which skaters can jump while being forgiving enough to avoid injury to the skaters.

What is claimed is:  
     
         1 . A jump bar stand for skaters, skateboarders and the like, said stand comprising: 
 an elongated post having an end segment;    a base connected to the end segment of the post above the base so as to support the post vertically, and    an elongated jump bar having an end swivelly connected to the post so that the jump bar extends out perpendicular to the post at a variable angle thereabout.    
     
     
         2 . The stand defined in  claim 1  wherein the base comprises a molded plastic member having a centrally located, vertical socket for snugly receiving said end segment of the post.  
     
     
         3 . The stand defined in  claim 2  wherein the socket has a cylindrical wall.  
     
     
         4 . The stand defined in  claim 2  wherein the socket has a clover leaf-shaped wall with a plurality of lands resiliently engaging the end segment of the post received in said socket so that upon side impact the post will be released readily from the base.  
     
     
         5 . The stand defined in  claim 1  and further including means for adjustably setting the elevation of the jump bar on the post.  
     
     
         6 . The stand defined in  claim 1  wherein 
 said post has a circular cross-section, and  
 said end of the jump bar includes a clip having spaced-apart, opposing, resilient clip arms which clip to the post so as to allow the jump bar to slide along and pivot on the post.  
 
     
     
         7 . The stand defined in  claim 6  and further including interfitting surfaces on the clip and post for adjustably setting the elevation of the jump bar on the post.  
     
     
         8 . The stand defined in  claim 7  wherein the interfitting surfaces include 
 a series of keyways spaced along the post, and  
 at least one key on the clip which engages in the keyways when the clip is positioned at selected elevations on the post.  
 
     
     
         9 . The stand defined in  claim 7  wherein the interfitting surfaces include 
 a series of keys spaced along the post, and  
 at least one keyway on the clip which receives the keys when the clip is positioned at selected elevations on the post.  
 
     
     
         10 . The stand defined in  claim 1  wherein the base, the post and the jump bar are all of a weather-resistant plastic material.  
     
     
         11 . The stand defined in  claim 10  wherein the base, post and jump bar are all of UV-stabilized high density polyethylene and/or polypropylene.  
     
     
         12 . The stand defined in  claim 1  wherein the base and jump bar are of a weather-resistant plastic material and the post is a cylindrical metal tube or pipe.  
     
     
         13 . The stand defined in  claim 1  and further including a second elongated jump bar having an end swivelly connected to the post, said second jump bar extending out horizontally from the post and being oriented on the post at a different angle from the first-mentioned jump bar.  
     
     
         14 . The stand defined in  claim 1  wherein the base is composed of two substantially identical sections with interfitting surfaces enabling the two sections to be keyed together about the end segment of the post.  
     
     
         15 . A jump bar stand for skaters, skateboarders and the like, said stand comprising 
 a stable base;    an elongated post extending up from the base, said post having height demarcations at spaced-apart locations along its length;    an elongated rigid arm having an end formed as a clip which resiliently grips the post so that the arm can slide along and about the post and be positioned on the post at any one of said demarcations said arm also being separable from the post when impacted from above.    
     
     
         16 . The stand defined in  claim 15  wherein said clip includes a portion which interfits with said any one of the demarcations to releasably set the arm at that height on the post.  
     
     
         17 . The stand defined in  claim 16   wherein the demarcations are circular, and    the clip portion includes a rib for releasably engaging in said grooves.    
     
     
         18 . The stand defined in  claim 16  wherein 
 the demarcations are circular flanges on the post, and  
 the clip portion includes a groove shaped to releasably receive said flanges.  
 
     
     
         19 . The stand defined in  claim 15  wherein the arm includes a jog adjacent to the clip which offsets the clip from the remainder of the arm in a direction along the post a distance substantially equal to the spacing of said demarcations.  
     
     
         20 . The stand defined in  claim 19  and further including a second similar arm whose clip grips the post such that the clip is offset in the opposite direction from the clip of the first mentioned arm.  
     
     
         21 . The stand defined in  claim 15  wherein the base is composed of two substantially identical sections with interfitting surfaces enabling the two sections to be keyed together about the end segment of the post.  
     
     
         22 . The stand defined in  claim 15  wherein 
 the post comprises a cylindrical tube or pipe, and  
 said demarcations are circular grooves spaced along the tube or pipe.  
 
     
     
         23 . The stand defined in  claim 15  wherein 
 the post comprises a unitary molded plastic part composed of elongated intersecting plate-like portions having edges which define an imaginary cylinder, and  
 said demarcations are circular flanges which extend out from said edges at spaced-apart locations along said plate-like portions, said flanges being concentric to said imaginary cylinder.  
 
     
     
         24 . The stand defined in  claim 15  wherein 
 said base has a centrally located vertical socket, and  
 said post has a lower end segment sized to plug into said socket.  
 
     
     
         25 . The stand defined in  claim 15  wherein 
 the post has a lower end segment slidably received in a socket in the base, and  
 the socket has a clover leaf-shaped wall with a plurality of lands resiliently engaging said lower end segment of the post so that the post is supported upright by the base yet, upon side impact, will be released readily from the base.
