Abstract
In one embodiment of the invention, a press assembly includes a gear assembly, a threaded rod, and a roller assembly. The gear assembly causes a rotational movement when activated. The threaded rod is coupled to the gear assembly and rotates in direction of the rotational movement caused by the gear assembly. The roller assembly is coupled to the threaded rod and moves linearly between a first end and a second end along guide slots when the threaded rod rotates.
Claims30
An apparatus comprising:
- a gear assembly to cause a rotational movement when activated;
- a threaded rod coupled to the gear assembly the threaded rod rotating in direction of the rotational movement caused by the gear assembly;
- a roller assembly coupled to the threaded rod, the roller assembly moving linearly between a first end and a second end along guide slots of a housing when the threaded rod rotates;
- an activator coupled to the gear assembly to activate the gear assembly to cause the rotational movement;
- a winder assembly coupled to the gear assembly to control the rotational movement;
- and
- a rotation lock assembly coupled to the activator to cause a locking action to the first gear, wherein the gear assembly comprising:
- a first gear having a first plurality of teeth coupled to the winder assembly, the first gear rotating in the first rotational direction when the winder assembly is activated to cause the roller assembly move linearly from the first end to the second end, the first gear rotating in the second rotational direction when the activator is activated to cause the roller assembly move linearly from the second end to the first end, and
- a second gear having a second plurality of teeth configured to fit the first plurality of teeth of the first gear, the second gear rotating in the second and first rotational directions when the first gear rotates in the first and second, respectively, rotational directions.
