Lockout mechanism for a weight stack exercise machine
View Patent ↗A lockout mechanism for a selection mechanism on an exercise machine, the selection mechanism being associated with a carriage for selectively carrying load. The carriage may include a support system adjustable by the selection mechanism for adjusting the amount of load to be carried. The lockout mechanism may include a lockout member configured to prevent adjustment of the selection mechanism during exercise.
1. A lockout mechanism for a selection mechanism on an exercise machine, the selection mechanism operatively associated with a carriage for selectively carrying load, the carriage including a support system adjustable by the selection mechanism for adjusting the amount of load to be carried, the lockout mechanism comprising:
a lockout member configured to prevent adjustment of the selection mechanism during exercise, the lockout member including an engaged position and a disengaged position, the lockout member comprising an end with a head configured to abut the selection mechanism in the engaged position thereby preventing adjustment of at least a first selection element of the selection mechanism;
an actuation member configured to move the lockout member from the engaged position to the disengaged position; and
the lockout member is pivotable between the engaged position and the disengaged position.
2. The lockout mechanism of claim 1 , wherein the lockout member is biased towards an engaged position.
3. The lockout mechanism of claim 2 , wherein the actuation member comprises a rod, the rod is connected to the lockout member with a link, and horizontal motion of the lockout member relative to the rod is accommodated by the link.
4. A lockout mechanism for a selection mechanism on an exercise machine, the selection mechanism operatively associated with a carriage for selectively carrying load, the carriage including a support system adjustable by the selection mechanism for adjusting the amount of load to be carried, the lockout mechanism comprising:
a lockout member configured to prevent adjustment of the selection mechanism during exercise, the lockout member including an engaged position and a disengaged position, the lockout member comprising an end with a head configured to abut the selection mechanism in the engaged position thereby preventing adjustment of at least a first selection element of the selection mechanism; and
an actuation member configured to move the lockout member from the engaged position to the disengaged position, wherein the actuation member is displaceably positioned on the carriage and is moveable between a lockout releasing position and an inactive position, the lockout releasing position causing the lockout member to be positioned in a disengaged position.
5. The lockout mechanism of claim 4 , wherein the actuation member is configured to abut a stop on the exercise machine when the carriage is in a rest position, the abutment of the stop causing the actuation member to be positioned in the lockout releasing position.
6. The lockout mechanism of claim 5 , wherein moving the carriage out of the start position causes the actuation member to move away from the stop and move to the inactive position.
7. A lockout mechanism for a selection mechanism on an exercise machine, the selection mechanism operatively associated with a carriage for selectively carrying load, the carriage including a support system adjustable by the selection mechanism for adjusting the amount of load to be carried, the lockout mechanism comprising:
a lockout member configured to prevent adjustment of the selection mechanism during exercise, the lockout member including an engaged position and a disengaged position, the lockout member comprising an end with a head configured to abut the selection mechanism in the engaged position thereby preventing adjustment of at least a first selection element of the selection mechanism; and
an actuation member configured to move the lockout member from the engaged position to the disengaged position, wherein the lockout member includes a secondary end comprising a hook configured to hook or abut at least a second selection element of the selection mechanism in the engaged position thereby preventing adjustment of the at least the second selection element of the selection mechanism.
8. The lockout mechanism of claim 7 , wherein the lockout member includes a crescent shaped body and is pivotable about a pivot point, the pivot point located between the primary and secondary ends.
9. The lockout member of claim 8 , wherein the first selection element includes a dial and the selection element includes a lever, the primary end of the lockout member being adapted to operably engage the dial and the secondary end of the lockout member being adapted to operably engage the lever.
10. The lockout member of claim 9 , wherein rotation of the dial causes rotation of a shaft including a ratchet gear attached thereto and engaged by a pawl, the primary end of the lockout member abutting the pawl in the engaged position, thereby preventing rotation of the ratchet gear and the shaft.
11. The lockout member of claim 9 , wherein the lever comprises a first selection position and a second selection position, the lever including a locking ridge and the locking member including an abutting surface, the locking ridge received in a recess formed in the secondary end of the lockout member when the lever is in the first selection position, and being abutted against the abutting surface in the engaged position when the lever is in the second selection position.
