Abstract
A weight lifting exercising device includes a number of weight plates slidably attached to a frame with a weight guide rod, two cam members pivotally attached to the frame, two cables coupled between the cam members and the weight plates for moving the selected number of the weight plates up and down along the weight guide rod, and an operating device engaged with the cam members for rotating either of the cam members to actuate either of the cables to move the weight plates up and down along the weight guide rod and for allowing the user to lift and to exercise the weight members either by pulling or pushing a force transfer member and for training or exercising the lower or the upper muscle groups of the users.
Claims11
A weight lifting exercising device comprising:
- a frame including at least one weight guide rod,
- a plurality of weight plates slidably attached onto said at least one weight guide rod and movable up and down along said at least one weight guide rod,
- a first cam member and a second cam member pivotally attached to said frame with a spindle,
- a first cable selectively coupling said first cam member to a selected number of said weight plates for selectively moving the selected number of said weight plates up and down along said at least one weight guide rod,
- a second cable selectively coupling said second cam member to a selected number of said weight plates for selectively moving the selected number of said weight plates up and down along said at least one weight guide rod, and
- an operating device engaged with said first cam member and said second cam member for selectively rotating either of said first or said second cam member relative to said frame, and for actuating either of said first or said second cable to move said weight plates up and down along said at least one weight guide rod, said operating device including a rotary member rotatably attached to said spindle, and an actuating member attached to said rotary member and engageable with either of said first or said second cam member for rotating either of said first or said second cam member relative to said frame when said rotary member is rotated relative to said frame, a force transfer member attached to said rotary member for rotating said rotary member relative to said frame, a crank attached to said rotary member, and said force transfer member being adjustably attached to said crank with a shank and a latch device for rotating said rotary member relative to said frame.
2-5. (canceled)
A weight lifting exercising device comprising:
- a frame including at least one weight guide rod, and including a floating pulley assembly having two pulleys,
- a plurality of weight plates slidably attached onto said at least one weight guide rod and movable up and down along said at least one weight guide rod,
- a first cam member and a second cam member pivotally attached to said frame with a spindle,
- a first cable selectively coupling said first cam member to a selected number of said weight plates for selectively moving the selected number of said weight plates up and down along said at least one weight guide rod,
- a second cable selectively coupling said second cam member to a selected number of said weight plates for selectively moving the selected number of said weight plates up and down along said at least one weight guide rod, and said pulleys of said floating pulley assembly of said frame being engaged with said first and said second cables respectively, and
- an operating device engaged with said first cam member and said second cam member for selectively rotating either of said first or said second cam member relative to said frame, and for actuating either of said first or said second cable to move said weight plates up and down along said at least one weight guide rod, and
- said frame including an upper beam and a lower beam, a first wheel and a second wheel attached to said upper beam, and a third wheel attached to said lower beam, said first cable being engaged with said first wheel and then engaged with a first of said pulleys of said floating pulley assembly and then engaged with said second wheel, and including a first end coupled to said weight plates and a second end coupled to said first cam member, said second cable being engaged with said third wheel and then engaged with a second of said pulleys of said floating pulley assembly, and including a first end coupled to said frame and a second end coupled to said second cam member.
