Orthopedic brace securing and tensioning system
An attachment system for an orthopedic brace incorporates at least one cinching system assembly having a knob rotatable in a first direction and a second direction. At least one cinching plate is engaged by the knob for rotation in the first direction in a first orientation and transitions to a second orientation upon rotation in the second direction. A ratchet wheel is engaged by the cinching plate in the first orientation for rotation in the first direction. At least one ratchet arm engages the ratchet wheel for ratcheting operation and is engaged by the cinching plate in the second orientation for disengagement from the ratchet arm. A shaft is rotated in response to rotation of the ratchet wheel and a strap is extendible from and retractable on the shaft upon rotation of the shaft.
1. A strap quick disconnect assembly mountable to supports of an orthopedic brace, said quick disconnect assembly comprising:
a capture shoe with a guidance flap;
a strap tip having a semi-circular end, a receiving end of the capture shoe having a semi-circular profile;
a resiliently depressible tongue extending from a surface of the strap tip to be engaged in a capture bracket;
a release button resiliently mounted to the capture bracket depressable to resiliently deform and flatten the tongue into the tip and release the tip from the capture bracket; and
a leaf spring in the capture shoe resiliently engaged by the strap tip upon insertion, said spring urging the tip out of the capture shoe upon flattening of the tongue.
2. The strap quick disconnect assembly as defined in claim 1 wherein the button extends through a mating hole in a support of an orthopedic brace allowing the strap quick disconnect assembly to be mounted on an interior surface of the support.
3. The strap quick disconnect assembly as defined in claim 1 wherein the semi-circular end of the strap tip and the semi-circular profile of the receiving end of the capture shoe provide the ability for the strap tip to swivel in the capture shoe through an angle about a nominal insertion axis before contact between a neck extending from the tip and walls of an insertion slot in the capture shoe thereby allowing an associated strap to assume a natural angle about a posterior portion of a leg without bending or cutting into soft flesh.
4. The strap quick disconnect assembly as defined in claim 3 wherein the neck terminates in a flanged attachment into which the strap is secured.
5. The strap quick disconnect assembly as defined in claim 3 wherein the neck terminates in a D-ring.
