Abstract
A device for providing rotational and axial locking capability using a wireform with at least one wrap. The device requires very low actuation forces. The wireform can be constructed with end features that provide a specific tension such that when the device is engaged a differential slip torque in a clockwise and counterclockwise rotational direction is developed.
Claims20
A locking device comprising:
- a rotatable cylinder;
- a body member;
- a lever mounted to the body member, the lever being rotatable between an engaged position and a disengaged position;
- and
- a shaped wireform having a wrap portion and opposing first and second ends, the wrap portion being arranged concentric with the cylinder, the first end being mounted to the body member, and the second end being mounted to the lever, wherein when the lever is in the engaged position the wireform engages a surface of the cylinder to limit rotation of the cylinder, and when the wireform is in the disengaged position the wireform permits rotation of the cylinder.
A wireform clamp locking device comprising:
- a body section having a first aperture;
- a rotatable cylinder positioned through the first aperture of the body section;
- a lever rotatably connected to the body section;
- and
- a shaped wireform having at least one wrap of a wrapped section selectively engageable to a surface of the cylinder, wherein a first end of the wireform is connected to the lever and a second end of the wireform is connected to a portion of the body section, and rotation of the lever moves the wireform between engaged and disengaged positions.
A wireform locking device comprising:
- a rotatable cylinder having a passage defined therethrough;
- a body section positioned at least partially within the passage and being fixed relative to the cylinder;
- a rotatable cam;
- and
- a shaped wireform positioned at least partially within the passage and having a wrapped section, wherein rotation of the cam provides selective engagement of the wrapped section to an inner surface of the passage to limit rotation of the cylinder relative to the body section.
A method of operating a wireform locking device, wherein the locking device includes a rotatable cylinder, a lever, and a shaped wireform, the wireform having a wrapped section that selectively engages to a surface of the cylinder, the method comprising:
- toggling the lever between an engaged position and a disengaged position, wherein in the engaged position the wireform is moved into engagement with the cylinder to limit rotation of the cylinder, and in the disengaged position the wireform permits unrestricted rotation of the cylinder.
