Abstract
A hand-held lift device forming a part of a weight lifting apparatus in performing double-joint multiple function exercises with the aid of an inertial resistance mechanism which is made up of the combination of a pivotally mounted linear actuator and dampener member, both of which can be adjusted to control the amount of inertial resistance to each exercise being performed, and a flexible cable serves as the resistance member between the linear actuator, dampener and lift device.
Claims18
In weight lifting apparatus wherein a lift device is engageable by an exerciser and is movable through a predetermined range of movement, the improvement comprising:
- a flexible resistance member for applying a selected amount of resistance to movement of said device, said resistance member affixed at one end to said device, a dampener member disposed at an opposite end of said resistance member;
- at least one pivotal arm member interposed between said dampener and said resistance member to establish a predetermined level of resistance to movement of said device;
- adjusting means between said arm member and said resistance member to vary the level of resistance to movement of said device including a fixed support member, and pivot means for pivotally connecting said arm member to said fixed support member to establish a fulcrum about which said arm member is pivoted in response to movement of said resistance member;
- and
- means for adjustably connecting said arm member to said support member whereby to adjust the length of a moment arm established between said cable and said support member.
In weight lifting apparatus wherein a lift device is engageable by an exerciser and is movable through a predetermined range of movement, the improvement comprising:
- a resistance member for applying a selected amount of resistance to movement of said device, said resistance member including a cable affixed at one end to said device and linear force actuating means being secured to an opposite end of said cable, a fixed support member, said actuating means including substantially perpendicular arm members interposed between said support member and said cable, and means for adjustably connecting one of said arm members to said support member whereby to adjust the length of a moment arm established between said cable and said support member.
Exercise apparatus for human exerciser to perform bicep curls in which arms of the exerciser are lifted from a position hanging freely down on opposite sides of the body to a raised overhead position comprising:
- a pair of hand grip members;
- and
- means suspending said grip members on opposite sides of the exerciser, said suspension means including rotational support means constraining the arms to rotate upwardly about the shoulders together with upward bending of the forearms about the elbows as said grip members are grasped in each hand of the exerciser and swung upwardly about said suspension means to a raised position over the head of the exerciser, said rotational support means including upper and lower intermeshing gears, and means operatively connecting said grip members to said lower gears whereby upward movement of said grip members causes said lower gears to undergo planetary rotation about said upper gears.
Weight lifting apparatus adapted for a human exerciser to perform double joint muscle movements comprising:
- a frame including a seat rest at one end of said frame;
- a pair of hand grip members, means suspending said grip members on opposite sides of said exerciser when seated upon said seat rest, said suspension means including rotational support means constraining the arms of the exerciser for movement upwardly about the shoulders and simultaneous upward bending of the forearms about the elbows when the exerciser swings the hand grips upwardly, said rotational support means including upper and lower intermeshing gears, and means operatively connecting said grip members to said lower gears whereby upward movement of said grip members causes said lower gears to undergo planetary rotation about said upper gears;
- and
- a resistance member for applying a selected amount of resistance to movement of said grip members, said resistance member fixed at one end to said rotational support means and a dampener at an opposite end of said resistance member to said rotational support means, at least one pivotal arm member disposed between said dampener and said resistance member to establish a predetermined level of resistance to movement of said grip members, a fixed support member, and adjusting means between said arm member and said support member to vary the level of resistance to movement of said grip members by said exerciser in performing double joint movements by adjusting the length of a moment arm established between said resistance member and said support member.
