Weight elevation systems, methods, and devices
View Patent ↗Systems, devices, and methods for elevating weights are disclosed. A lifting bar rotates about a rotating joint attached to a vertical support. As the system is engaged, the lifting rotates from a downward position parallel to the vertical support to a horizontal position, a hook on the lifting bar engaging the weight and lifting it.
1. A system for elevating a weight comprising:
a vertical support comprising:
a first slot configured to engage a rotating joint; and
a latch configured to hold a latch pin;
a latch release mechanism configured to release the latch pin from the latch;
a rotating joint that rotatably attaches a lifting bar to the vertical support;
the lifting bar comprising:
a hook configured to capture and hold the weight when the rotating joint moves the lifting bar to a horizontal position, perpendicular to the vertical support;
a lock pin configured to engage the vertical support when the rotating joint moves the lifting bar to the horizontal position;
a latch pin configured to engage the latch when the rotating joint lowers the lifting bar to a parallel position with the vertical support;
a second slot configured to engage the rotating joint; and
an angular momentum imparting device configured to continuously impart a torque to rotate the lifting bar towards the horizontal position;
wherein the lifting bar is configured to be rotated downward by a user to engage the latch pin with the latch, thereby latching the lifting bar down;
wherein the latch is released by the latch release mechanism, allowing the angular momentum imparting device to rotate the lifting bar to the horizontal position, the hook engaging and lifting the weight; and
wherein the lock pin engages and locks the lifting bar in the horizontal position.
2. The system of claim 1 , wherein the lock pin is spring actuated and the lock pin is configured to be disengaged by the user, allowing rotation of the rotating joint.
3. The system of claim 1 , further comprising a lever arm attached to the lifting bar and configured to provide the user sufficient leverage to overcome the torque of the angular momentum imparting device.
4. The system of claim 3 , wherein the lever arm comprises a handle that folds out or telescopes out to maximize the leverage.
5. The system of claim 1 , wherein the angular momentum imparting device comprises a piston, a torsion spring, a counterweight, or a motor.
6. The system of claim 5 , wherein the piston is attached by a first ball joint to the vertical support and by a second ball joint to the lifting bar.
7. The system of claim 5 , wherein the piston is attached by a first hinge joint to the vertical support and by a second hinge joint to the lifting bar.
8. The system of claim 1 , wherein two of the systems are provided to a bench press, the weight is a barbell, and the latch release mechanism is configured to be actuated by the user to lift the barbell for the user.
9. The system of claim 1 , wherein the latch release mechanism is configured to be actuated by the user pulling an ankle strap connected to a cable by voice activation of a controller, by a foot pedal, by a camera and controller with situational recognition software, by a blood oxygen sensor, by a wireless button on the barbell, or by a combination thereof.
10. The system of claim 1 , wherein two of the systems are provided to a squat rack or preacher curl bench, the weight is a barbell or other bar carrying weight, and the latch release mechanism is configured to be actuated by the user to lift the barbell for the user.
11. A method for elevating a weight comprising:
providing a lifting bar comprising a hook, a lock pin, and a latch pin;
providing a vertical support comprising a latch;
wherein the lifting bar is rotatably attached to the vertical support;
providing an angular momentum imparting device that imparts a torque to rotate the lifting bar towards a horizontal position;
locking the lifting bar downward, parallel to the vertical support and below the weight, by engaging the latch pin into the latch;
releasing the latch by engaging a latch release mechanism, causing the lifting bar to rotate to the horizontal position, the hook to engage the weight, the lifting bar to elevate the weight, and the lock pin to engage the lifting bar in the horizontal position.
12. The method of claim 11 , wherein the lock pin is spring actuated and further comprising the user disengaging the lock pin, allowing rotation of the rotating joint.
13. The method of claim 11 , further comprising providing a lever arm attached to the lifting bar of sufficient length so that the user can apply a downward force that overcomes the torque of the angular momentum imparting device.
14. The method of claim 13 , wherein the lever arm comprises a handle that folds out or telescopes out to provide the sufficient length.
15. The method of claim 11 , wherein the angular momentum imparting device comprises a piston, a torsion spring, a counterweight, or a motor.
16. The method of claim 15 , wherein the piston is attached by a first ball joint to the vertical support and by a second ball joint to the lifting bar.
17. The method of claim 15 , wherein the piston is attached by a first hinge joint to the vertical support and by a second hinge joint to the lifting bar.
18. The method of claim 11 , further comprising providing two of the systems to a bench press, wherein a user lifts a barbell and actuates the latch release mechanism to lift the barbell for the user.
19. The method of claim 11 , further comprising actuating the latch release mechanism by a user pulling an ankle strap connected to a cable by voice activation of a controller, by a foot pedal, by a camera and controller with situational recognition software, by a blood oxygen sensor, by a wireless button on the barbell, or by a combination thereof.
20. A system for elevating a weight comprising:
a vertical support comprising a first slot configured to engage a rotating joint;
a lifting bar comprising:
a hook configured to capture and hold the weight when the rotating joint moves the lifting bar to a horizontal position, perpendicular to the vertical support; and
a second slot configured to engage the rotating joint;
the rotating joint configured to allow the lifting bar to rotate relative to the vertical support; and
a motor configured to rotate the lifting bar downward when the motor receives instructions from the user and to impart angular momentum to rotate the lifting bar to the horizontal position when a safety switch engages;
wherein as the safety switch engages, the motor rotates the lifting bar to the horizontal position, the hook engaging and lifting the weight.
