Repositioning point of actuation for an exercise appliance
An exercise machine comprises an arm support, including: a carriage configured to slide within a track attached to the exercise machine; and a support assembly that floats the carriage relative to the track, wherein the support assembly is disengaged by the application of force via the arm. An exercise machine comprises a rotatable column, wherein the column supports an arm, and a gear detent mechanism to support a discrete number of positions for the rotatable column. An exercise machine comprises a tiltable arm, and a mechanism to support a discrete number of positions for the tiltable arm.
1. An exercise machine, comprising:
a load element;
a column;
a carriage configured to engage with the column and travel along the column, wherein the carriage is floated relative to the column at least in part by one or more spring plates; and
a load arm supported by the carriage providing a load path along which a cable is routed from the load element to an actuator wherein the load arm is positioned with at least three degrees of freedom by movement of the carriage along the column, rotation of the column, and tilting of the load arm.
2. The exercise machine as recited in claim 1 , wherein the column is designed to be oriented in a substantially vertical direction when the exercise machine is mounted.
3. The exercise machine as recited in claim 1 , wherein the column comprises a track.
4. The exercise machine as recited in claim 1 , wherein the load arm includes a pulley to route the cable.
5. The exercise machine as recited in claim 1 , wherein the carriage supports the load arm translating vertically along the column.
6. The exercise machine as recited in claim 1 , wherein the carriage includes a support assembly that includes wheels and springs.
7. The exercise machine as recited in claim 1 , wherein a sagittal gear on the carriage enables tilting of the load arm at discrete angles.
8. The exercise machine as recited in claim 1 , further including a remote control enabled solenoid that locks rotation of the column.
9. The exercise machine as recited in claim 1 , further including second load arm.
10. The exercise machine as recited in claim 1 , wherein movement of the carriage is indexed by an index pin.
11. The exercise machine as recited in claim 1 , wherein the carriage includes a sagittal gear that includes teeth and a locking member that engages the teeth.
12. The exercise machine as recited in claim 1 , wherein the carriage includes a sagittal gear that includes teeth and a locking member that engages the teeth and wherein the load arm includes a handle that when pulled, causes the locking member to be disengaged from the sagittal gear, enabling the load arm to tilt vertically.
13. A method of providing exercise resistance comprising:
generating a load using a load element;
coupling the load element to an actuator via:
a column;
a carriage configured to engage with the column and travel along the column, wherein the carriage is floated relative to the column at least in part by one or more spring plates; and
a load arm supported by the carriage providing a load path along which a cable is routed from the load element to the actuator wherein the load arm is positioned with at least three degrees of freedom by movement of the carriage along the column, rotation of the column, and tilting of the load arm.
14. The method of providing exercise resistance as recited in claim 13 , wherein the load is coupled to the actuator using a pulley to route the cable.
15. The method of providing exercise resistance as recited in claim 13 , wherein the carriage is translated vertically along the column.
16. The method of providing exercise resistance as recited in claim 13 , wherein the load arm is tilted with respect to the carriage using a sagittal gear.
