Exercise machine handle system
An exercise machine handle system which provides a unique handle and rotatable handle hub configuration to aid in performing a variety of exercises. The exercise machine handle system generally includes one or more handle assemblies each having a mounting bracket adapted to be removably secured to an exercise machine and including an upwardly-extending mounting hub shaft. A handle hub having a pair of curved handles extending in opposite directions therefrom is rotatably securable around an upper end of the handle hub shaft into a variety of locked positions. A third curved handle extends from an upper end of the handle hub in a similarly rotatably securable position. By removably securing one or more handle assemblies to an exercise machine, a user can benefit from a wide range of exercises supported by the adjustable handle assemblies.
1. A handle assembly for an exercise machine, comprising:
a mounting bracket secured to an exercise machine;
a mounting hub shaft extending upwardly from said mounting bracket;
a handle hub rotatably secured to an upper end of said mounting hub shaft by an adjustment assembly, said handle hub being adapted to be locked in a plurality of rotational positions with respect to said mounting hub shaft; and
a first handle extending from said handle hub;
wherein said adjustment assembly is operable to longitudinally move said handle hub from a locked state to an unlocked state, wherein said locked state prevents rotation of said handle hub and wherein said unlocked state allows free rotation of said handle hub;
wherein said adjustment assembly comprises an anchoring member positioned within an inner channel of said mounting hub shaft, an upper end of said anchoring member being fixedly secured within said handle hub, wherein said anchoring member is comprised of a base portion and a rod portion extending upwardly from said base portion.
2. The handle assembly for an exercise machine of claim 1 , further comprising a coil spring and a tube member each surrounding said rod portion of said anchoring member, said tube member being positioned above said coil spring.
3. The handle assembly for an exercise machine of claim 2 , wherein said adjustment assembly further comprises a collar fixedly secured to said upper end of said mounting hub shaft, wherein said rod portion of said anchoring member extends through said coil spring, said tube member and said collar.
4. The handle assembly for an exercise machine of claim 3 , wherein said collar includes a plurality of radial projections which define a plurality of radial slots, wherein handle hub includes a plurality of internal locking members for selectively engaging with said plurality of radial slots to lock said handle hub in said locked state.
5. The handle assembly for an exercise machine of claim 4 , said handle hub being adapted to freely rotate after application of upward force so as to disengage said locking members from said radial slots, wherein said coil spring is downwardly biased to re-engage said locking members with said radial slots absent said upward force.
6. The handle assembly for an exercise machine of claim 1 , further comprising an upper handle rotationally secured to said handle hub, wherein a proximal end of said upper handle includes a collet adapted to frictionally engage with said handle hub.
7. A handle assembly for an exercise machine, comprising:
a mounting bracket secured to an exercise machine;
a mounting hub shaft extending upwardly from said mounting bracket;
a handle hub rotatably secured to an upper end of said mounting hub shaft by an adjustment assembly, said handle hub being adapted to be locked in a plurality of rotational positions with respect to said mounting hub shaft;
a first handle extending from said handle hub; and
an upper handle rotationally secured to said handle hub, wherein a proximal end of said upper handle includes a collet adapted to adjustably engage with said handle hub.
