Abstract
A quick-release collar is provided for securing weight plates to a weight bar in the sport of weight lifting. The collar includes a collar body defining an opening for receiving the weight bar, and defining a tangential ramp leading to the opening. A lock rod engages the ramp, and a tie rod extends through the collar to the lock rod. A handle threads onto the tie rod and, when rotated, tensions the tie rod, pulling the lock rod against the ramp into a securely wedged, interlocked engagement with the bar.
Claims12
A collar used to secure weight plates to a weight bar in the sport of weight lifting, comprising:
- a collar body with a first surface defining an opening adapted to slidably receive a weight bar, and including a ramp positioned radially outward from the opening that defines an angle to an adjacent portion of the first surface;
- a lock member engaging the ramp;
- and
- a biasing member connected to the lock member and operable to move the lock member along the ramp from a release position where the opening of the collar body is unobstructed and is adapted to slidably receive the bar, to a wedged locked position where lock member begins to intrude into the opening, whereby the collar body, when the biasing member is in the wedged locked position, is adapted to be locked onto the bar to securely hold weight plates on the bar.
A collar used to secure weight plates to a weight bar in the sport of weight lifting, comprising:
- a collar body with a first surface defining an opening adapted to slidably receive a weight bar;
- a lock member positioned adjacent the opening and configured to slide in a transverse and tangential direction relative to the first surface between a release position where the opening of the collar body is unobstructed and adapted to slidably receive the bar, to a wedged locked position where the lock member begins to intrude into the opening in a manner adapted to clamp the bar in the opening;
- and
- an elongated biasing member positioned transverse to the opening in the collar body, the biasing member being operably coupled to the lock member and including a handle that can be manipulated to move the lock member between the release position and the wedged locked position.
A method comprising steps of:
- providing a collar including a collar body, a lock rod, and a tangentially-positioned biasing device connected to the lock rod and coupled to the collar body, the collar body defining an opening and the lock rod being movably positioned adjacent the opening;
- and
- manipulating the biasing device to slide the lock rod in a transverse and tangential direction relative to an inner surface of the opening from a release position where the lock rod is not in the opening, to a locking position partially in the opening where the lock rod is adapted to wedge against a weight bar in the opening of the collar body, the wedging action locking the collar onto the weight bar and in turn retaining any weight plates on the weight bar.
