Abstract

A rebounder comprising an encompassing frame supported by plural legs has a substantially rigid platform suspended on the frame. The platform has a substantially rigid base and a pad of resilient material is secured on the base. A vertical handhold frame may have a directly attached handhold or a rotating handhold, which may be attached by elastic connections.

1 . A portable exercise system comprising: 
 a frame;    a plurality of legs supporting the frame;    a substantially rigid jumping bed; and    a plurality of elastic members connected between the jumping bed and the frame.    
   
   
       2 . The portable exercise system of  claim 1 , wherein the jumping bed is a platform which comprises: 
 a substantially rigid base having an upper surface; and    a resilient pad on the upper surface of the base.    
   
   
       3 . The portable exercise system of  claim 2 , wherein the pad comprises flexible elastomeric foam material.  
   
   
       4 . The portable exercise system of  claim 2  further comprising a cover over the pad.  
   
   
       5 . The portable exercise system of  claim 2 , wherein the pad includes at least one pneumatic chamber.  
   
   
       6 . A portable exercise system comprising: 
 a bed support frame;    a plurality of legs supporting the bed support frame;    a jumping bed;    a plurality of elastic members connected between the jumping bed and the bed support frame; and    a handhold frame that extends upwardly from the bed support frame and that has an upper end or ends of adjustable height.    
   
   
       7 . The portable exercise system of  claim 6  further comprising a handhold supported by the upwardly extending frame.  
   
   
       8 . A portable exercise system comprising: 
 a bed support frame;    a plurality of legs supporting the bed support frame;    a jumping bed;    a plurality of elastic members connected between the jumping bed and the bed support frame;    a handhold frame that extends upwardly from the bed support frame;    a support member supported by the handhold frame;    a handhold member; and    one or more bearings that are slidably mounted between the support member and the handhold member such that the handhold member can rotate about a generally vertical axis and is supported by the support member.
