Digital weight cable machine with a passive tracking trolley

Abstract

An exercise machine may include a frame, one or more actuators, coupled to one or more cables to exert a load on the one or more cables, one or more tracks attached to the frame, and a trolley mounted on each of the one or more tracks. The trolley may slide unrestricted along a length of the one or more tracks. The trolley is configured to be coupled to the one or more cables. The trolley slides to track movement of a user to maintain a desirable direction of the force vector.

         2 . The exercise machine of  claim 1 , wherein each of the one or more tracks attach to the frame at a first joint that rotates the respective track relative to the frame, wherein each of the one or more tracks is rotatable to a first track position that is oriented horizontal to the ground and to a second track position that is oriented vertical to the ground. 
     
     
         3 . The exercise machine of  claim 1 , wherein a total length of each of the one or more tracks comprises at least 38″, or at least 42″, or at least 60″. 
     
     
         4 . The exercise machine of  claim 1 , wherein each trolley comprises a first loop arranged at a surface of the trolley facing away from the ground when the one or more tracks are in the first track position, the first loop configured to pass a respective one of the one or more cables. 
     
     
         5 . The exercise machine of  claim 1 , wherein each trolley comprises a second loop arranged at a second surface opposite of the first surface on the trolley, wherein in the second track position, the second surface faces a horizontal direction relative to the ground. 
     
     
         6 . The exercise machine of  claim 1 , wherein the one or more tracks comprise two tracks that are parallel to each other, wherein the respective trolley of the two tracks slide parallel to each other along the length of the two tracks. 
     
     
         7 . The exercise machine of  claim 6 , wherein each of the two tracks are fixed at opposite sides of the frame. 
     
     
         8 . The exercise machine of  claim 7 , further comprising a platform fixed to the frame, wherein the platform serves as a floor surface located between the two tracks. 
     
     
         9 . The exercise machine of  claim 8 , wherein the platform is connected to the frame at a second joint that rotates the platform to be oriented horizontally and serve as the floor surface between the two tracks in a first platform position, and to be oriented vertically in a second platform position. 
     
     
         10 . The exercise machine of  claim 8 , wherein the platform comprises a width between the two tracks of at least 20″, or at least 28″, or between 24″ and 42″. 
     
     
         11 . The exercise machine of  claim 8 , wherein the platform comprises a platform length of at least 38″, or at least 42″, or at least 60″. 
     
     
         12 . The exercise machine of  claim 8 , wherein the platform comprises a stiff planar surface having a thickness of at least 0.75″, or at least 1″, or at least 1.5″. 
     
     
         13 . The exercise machine of  claim 8 , wherein in the first track position, the one or more tracks attach to the platform which locks the one or more tracks fixed in the first track position. 
     
     
         14 . The exercise machine of  claim 13 , wherein the one or more tracks attach to a bracket that is fixed to an end of the platform that is away from the second joint. 
     
     
         15 . The exercise machine of  claim 13 , wherein the second joint comprises a first support arm on one side of the platform that is coupled between the platform and the frame, and a second support arm on an opposite side of the platform that is coupled between the platform and the frame. 
     
     
         16 . The exercise machine of  claim 1 , further comprising a computing device, wherein the computing device comprises one or processors configured to perform the following operations:
 displaying a user interface;   receiving a user input; and   controlling the one or more actuators to exert the load on the one or more cables, based on the user input.   
     
     
         17 . The exercise machine of  claim 8 , further comprising:
 a rack, coupled to or integrated with the frame, the rack comprising one or more vertical members and a shelf that is attached to the rack, the shelf being configured to hold a barbell on the one or more vertical members.   
     
     
         18 . The exercise machine of  claim 17 , wherein the rack comprises a plurality of holding positions for the shelf arranged vertically along different heights of the one or more vertical members. 
     
     
         19 . A method for manufacturing an exercise machine, comprising:
 providing a frame;   attaching one or more actuators to the frame, coupled to one or more cables to exert a load on the one or more cables;   attaching one or more tracks to the frame; and   mounting a trolley on each of the one or more tracks, wherein the trolley slides unrestricted along a length of the one or more tracks, and wherein the trolley is configured to be coupled to the one or more cables.   
     
     
         20 . The method of  claim 19 , wherein each of the one or more tracks attach to the frame at a first joint that rotates the respective track relative to the frame, wherein each of the one or more tracks is rotatable to a first track position that is oriented horizontal to the ground and to a second track position that is oriented vertical to the ground.
