Climbing exercise machine
An exercise machine creates a simulated continuous resisted climbing motion. The machine includes a floor- or ground-contacting base frame and two or more substantially vertically oriented uprights, wherein at least one upright is rigidly connected to the base frame. The machine further includes two handles and two foot pedals, each handle and each foot pedal being movably engaged with an upright for linear reciprocating motion along the upright. The handles and foot pedals are interconnected so that they move concurrently. An adjustable resistance mechanism may be operatively connected to the interconnection of the handles and foot pedals to provide adjustable resistance for the simulated continuous climbing motion.
1. A climbing exercise machine, comprising:
a base support frame configured to contact a floor or ground surface;
a first elongate upright having a first end and a second end, wherein the first end is rigidly connected to the base support frame at a first obtuse angle relative to the floor or ground surface;
a second elongate upright having a first end and a second end, wherein the first end is rigidly connected to the base support frame at a second obtuse angle relative to the floor or ground surface;
an elongate crossbar having a first end and a second end, wherein the first end of the elongate crossbar is rigidly connected to a middle, central, or intermediate portion of the first elongate upright and the second end of the elongate crossbar is rigidly connected to a middle, central, or intermediate portion of the second elongate upright;
a first movable and adjustable handle and a first movable and adjustable foot pedal, vertically spaced apart from each other and each being engaged with the first elongate upright to enable reciprocating linear movement along the first elongate upright;
a second movable and adjustable handle and a second movable and adjustable foot pedal, vertically spaced apart from each other and each being engaged with the second elongate upright to enable reciprocating linear movement along the second elongate upright; and
a linkage assembly, comprising a plurality of belts, the plurality of belts interconnecting the first movable and adjustable handle, the first movable and adjustable foot pedal, the second movable and adjustable handle, and the second movable and adjustable foot pedal, and an axle, housed within the crossbar and interconnecting the plurality of belts,
wherein the linkage assembly enables reciprocating concurrent movement of the first movable and adjustable handle, the first movable and adjustable foot pedal, the second movable and adjustable handle, and the second movable and adjustable foot pedal to simulate a continuous climbing motion for a user.
2. The climbing exercise machine of claim 1 , wherein the base support frame has the general shape of three sides of a rectangle.
3. The climbing exercise machine of claim 1 , wherein the linkage assembly further comprises a plurality of self-lubricating slides, wherein each of the plurality of self-lubricating slides is connected to one of the first movable and adjustable handle, the first movable and adjustable foot pedal, the second movable and adjustable handle, and the second movable and adjustable foot pedal.
