Abstract
An exercise apparatus includes a base and an elongated upright pillar connected to the base. The pillar has a plurality of stop positions therealong. A surrounding member is slidably mounted on the pillar and is sufficiently oversized to permit relative lengthwise slidable movement therealong. An elongated horizontal support bar is fixedly connected to the surrounding member. The horizontal support bar and the surrounding member is moveable between an upper and lower limit positions on the pillar. The surrounding member is selectively fixed to the pillar at the stop positions. The surrounding member slides relative to the pillar between stop positions. A lifting force is applied to the surrounding member by a mechanical lifting aid to assist the surrounding member when sliding relative to the pillar.
Claims4
An exercise apparatus comprising:
- a base;
- an elongated upright pillar connected to said base, said pillar having a plurality of stop positions therealong;
- a surrounding member slidably mounted on said pillar and being sufficiently oversized to permit relative lengthwise slidable movement therealong;
- an elongated horizontal support bar fixedly connected to said surrounding member, said horizontal support bar and said surrounding member being movable between upper and lower limit positions on said pillar, said surrounding member being selectively fixed to said pillar by a pin at said stop positions, said surrounding member sliding relative to said pillar between stop positions;
- a handle attached to said horizontal support bar;
- and
- means for applying a lifting force to said surrounding member to assist said surrounding member when sliding relative to said pillar, said applying means including an elastic cord connected to said base and to said surrounding member and a grooved guide which receives and guides the movement of the elastic cord connected to the top of the pillar.
