Adjustable basketball goal

Abstract

An adjustable basketball goal pivotally secured to a fixed support post with pairs of interengaged pivoted lever arms. A height adjustment mechanism is secured to the support post with an activation arm extending therefrom pivotally interconnected to one pair of said support arms. A gear rack portion of the activation arm is positioned for selective registration within a ratchet type adjustment mechanism having a gear rack engagement portion activation lever and a ratchet engagement pall providing for incremental self-elevation and lowering of the basketball goal in relation to the support post.

1 . An adjustable basketball goal for adjustment of height of a basketball goal above a playing surface comprises in combination,
 a rigid support, a basketball goal assembly, an upper support arm pair pivotally connected to the basketball goal and said rigid support,   a lower support arm pair pivotally connecting to the basketball goal and the rigid support,   said upper and lower arm pairs in spaced parallel paralligranic relation to one another where selective movement of said lower support arm pairs that deforms said upper arm pairs moving the basketball goal assembly.   
     
     
         2 . The adjustable basketball goal set forth in  claim 1  wherein said rigid support comprises,
 a hollow support post. 
 
     
     
         3 . The adjustable basketball goal set forth in  claim 1  wherein said basketball goal assembly comprises,
 a backboard, a basketball rim and net assembly on said backboard. 
 
     
     
         4 . The adjustable basketball goal set forth in  claim 1  wherein said lower support arm pair has parallel arm extensions from a pivot point on said rigid support,
 an indexing locking mechanism pivotally engaging the free ends of said parallel extensions, 
 movement of said indexing locking mechanisms selectively pivots said lower and upper support arm pairs in a parallelogram operation. 
 
     
     
         5 . The adjustable basketball goal set forth in  claim 4  wherein said indexing locking mechanism comprises,
 a backboard activation bar with a gear rack extending from said parallel arm extensions, 
 a ratchet actuation adjustment assembly engaging said activation bar for selective indexing movement thereto. 
 
     
     
         6 . The adjustable basketball goal set forth in  claim 4  wherein said indexing locking mechanism further comprises,
 a pivot lifting lever and a locking pawl for selective engagement with the gear rack on said activation bar for selective advancement, locking and release during height adjustment of the backboard activation bar and the basketball goal assembly. 
 
     
     
         7 . The adjustable basketball goal set forth in  claim 6  wherein said indexing locking mechanism further comprises,
 an open-ended housing having a pivoted activation lever fitting and a locking pawl pivot fitting for registration of the pivot lift lever and locking pawl respectively and a control lever for directional engagement of the activation bar. 
 
     
     
         8 . The adjustable basketball goal set forth in  claim 7  wherein said open ended housing is secured to said rigid support in spaced parallel relation thereto and in vertical spaced relation to said lower support arm pair.
