Abstract:
1. A regulating device for adjusting gymnastic machines having a first member and a second member slidable relative to the first member, the device comprising: a lever for manual selection of lock and release, associated with said first member; a toothed rod having teeth, associated with said second member; a pawl mechanically interlocked to said lever and selectively engageable in one of the teeth of said toothed rod to block said second member with respect to said first member in any position desired by the user of the gymnastic machine; said lever being rotatably carried with respect to said first member and being, in use, selectively movable from at least a first position of free sliding of said second member relative to said first member, wherein said pawl is completely released from said toothed rod, to at least a second position of snap sliding of said second member relative to said first member only in a given direction, wherein said pawl can be snap released from said toothed rod when a traction is exerted on the second member in said given direction, to at least a third position of blocking said second member relative to said first member, wherein said pawl is rigidly engaged in one of said teeth of said toothed rod; a first return means for mechanically coupling said first member to said lever to maintain, in use, in an elastically stable manner said lever in said third position of blocking said second member relative to said first member; and a second return means for coupling said first member to said pawl to maintain, in use, said pawl in an elastically stable and snap releasable engagement in one of said teeth of said toothed rod.
