Resistance multiplier
An exercise equipment, that includes (a) a frame that includes a vertically wall-mountable beam; (b) one or more brackets for connecting the vertically wall-mountable beam to a wall; (c) an arm that rotatable in relation to the vertically wall-mountable beam and is selectively positionable along the vertically wall-mountable beam; (d) a cable; (e) a resistance source, and (f) a cable transfer unit that is configured to convey the cable through a cable path formed within the frame.
1 . An exercise system, comprising:
an exercise machine, comprising: a wall mountable frame, an exercise machine cable, and a resistance source configured to apply resistance to the exercise machine cable; and
an add-on unit for selective use with the exercise machine, wherein the exercise machine is usable for performance of an exercise selectively with the add-on unit as well as independently of the add-on unit, wherein when the exercise machine is used independently of the add-on unit, the exercise machine cable is free of engagement with the add-on unit and a free end thereof is accessible for the performance of the exercise; and when the exercise machine is used with the add-on unit, the free end of the exercise machine cable is connected at least indirectly to the add-on unit, the add on add-on unit comprising:
a frame mechanically coupled to a pulley system, the pulley system comprising a plurality of sheaves, and
one or more add-on unit cables connectable, at least indirectly, to the exercise machine cable; the plurality of sheaves being configurable for modifying the resistance applied to the exercise machine cable when the exercise machine is used with the add-on unit and the free end of the exercise machine cable is connected to the one or more add-on unit cables via a connector or an interface.
2 . The exercise system according to claim 1 , wherein the frame of the add-on unit is configured to be positioned on a floor surface.
3 . The exercise system according to claim 2 , wherein the frame of the add-on unit is constructed to allow a user to stand thereon.
4 . The exercise system according to claim 1 , wherein the plurality of sheaves comprise at least:
a first sheave mechanically coupled to a first portion of the frame;
a second sheave configured to be coupled to a user interface; and
a third sheave mechanically coupled to a second portion of the frame.
5 . The exercise system according to claim 4 , wherein a position of the second sheave is adjustable between the first sheave and the third sheave to thereby modify the resistance.
6 . The exercise system according to claim 1 , wherein the pulley system is configured to multiply the resistance by a factor that exceeds one.
7 . The exercise system according to claim 1 , wherein the frame comprises a rectangular shape.
8 . The exercise system according to claim 1 , wherein the add-on unit further comprises a user interface, the user interface comprising a handle.
9 . The exercise system according to claim 1 , wherein the resistance source of the exercise machine is an electronically-adjustable weight resistance motor.
10 . The exercise system according to claim 1 , wherein the add-on unit is free of motors.
11 . The exercise system according to claim 1 , wherein the exercise machine comprises a handle or an accessory connected to the exercise machine cable for engagement by a user, when the exercise machine is used without the add-on unit.
12 . A method of modifying resistance in an exercise machine, the exercise machine comprising a wall mountable frame, an exercise machine cable, and a resistance source configured to apply resistance onto the exercise machine cable, the method comprising:
providing an add-on unit comprising a frame and a pulley system mechanically coupled to the frame; the pulley system comprising a plurality of sheaves, and one or more add-on unit cables, wherein the exercise machine is usable for performance of an exercise selectively with the add-on unit as well as independently of the add-on unit, wherein when the exercise machine is used independently of the add-on unit, the exercise machine cable is free of engagement with the add-on unit and a free end thereof is accessible for the performance of the exercise; and when the exercise machine is used with the add-on unit, the free end of the exercise machine cable is connected at least indirectly to the add-on unit;
connecting the one or more add-on unit cables at least indirectly to the free end of the exercise machine cable via a connector or an interface; and
configuring the pulley system to modify the resistance applied to the exercise machine cable.
13 . The method according to claim 12 , wherein configuring comprises adjusting a position of at least one of the plurality of sheaves.
14 . The method according to claim 12 , wherein modifying the resistance comprises multiplying the resistance by a factor that exceeds one.
15 . The method according to claim 12 , comprising positioning the frame of the add-on unit on a floor surface.
16 . The method according to claim 12 , wherein the add-on unit further comprises a user interface, the user interface comprising a handle.
