Flex lock for orthotic braces
A flex lock system for locking an orthotic brace having a push button for adjusting the range of flexion angles and a push button for adjusting the range of extension angles for the orthotic brace. The flex lock system has a tab having a receiving hole configured to fit around a push button and to prevent the push button from being depressed and adjusting the ranges of flexion or extension improperly. The flex lock system is made of a flexible material that has particular elasticity and compressibility to function as a flex lock as described.
1. A flex lock system for orthotic braces, comprising:
a circular hinge for an orthotic brace having a center region, a front face, and an outer circumference;
an upper strut of the orthotic brace being integrally formed with the circular hinge;
a lower strut of the orthotic brace being rotatably connected to the center region of the circular hinge to provide for flexion and extension ranges of motion about the circular hinge when the brace is worn by a user;
a first push button for adjusting the range of flexion for the orthotic brace via the lower strut, where the first push button is positioned on the outer circumference of the circular hinge in a direction perpendicular to the front face of the circular hinge;
a second push button for adjusting the range of extension for the orthotic brace via the lower strut, where the second push button is positioned on the outer circumference of the circular hinge in a direction perpendicular to the front face of the circular hinge;
a flex lock having a first end, a second end, and a center region wherein the center region of the flex lock is affixed to the center region of the circular hinge either directly or indirectly;
a first receiving hole positioned at the first end of the flex lock and a second receiving hole positioned at the second end of the flex lock, wherein when the first and second push buttons are received in a respective first and second receiving hole the rotatable adjustment of the lower strut is prevented; and
a first pull tab positioned at the first end of the flex lock to facilitate an association and a disassociation of the first push button with the first receiving hole and a second pull tab positioned at the second end of the flex lock to facilitate an association and a disassociation of the second push button with the second receiving hole.
2. The flex lock system of claim 1 , wherein the flex lock comprises an elastomeric material.
3. The flex lock system of claim 1 , wherein the flex lock comprises two separate portions each having a first end and a second end;
the first ends of each of the two separate portions being attached to the center region of the circular hinge; and
the second ends of each of the two separate portions each comprising a pull tab and a receiving hole for locking the orthotic brace in various flexion and extension positions.
4. A flex lock system for orthotic braces, comprising:
a circular hinge for an orthotic brace having a center region, a front face, and an outer circumference;
an upper strut of the orthotic brace being integrally formed with the circular hinge;
a lower strut of the orthotic brace being rotatably connected to the center region of the circular hinge to provide for flexion and extension ranges of motion about the circular hinge when the brace is worn by a user;
a first push button for adjusting the range of flexion for the orthotic brace via the lower strut, where the first push button is positioned on the outer circumference of the hinge in a direction perpendicular to the front face of the circular hinge;
a second push button for adjusting the range of extension for the orthotic brace via the lower strut, where the second push button is positioned on the outer circumference of the hinge in a direction perpendicular to the front face of the circular hinge; and
a flex lock comprising:
a first portion of the flex lock having a first end and a second end, wherein the second end is affixed to the center region of the circular hinge either directly or indirectly;
a second portion of the flex lock having a first end and a second end, wherein the second end is affixed to the center region of the circular hinge either directly or indirectly;
a first receiving hole positioned at the first end of the first portion of the flex lock, wherein when the first push button is received in the first receiving hole the adjustment of the lower strut in the flexion range of motion is prevented;
a second receiving hole positioned at the first end of the second portion of the flex lock, wherein when the second push button is received in the second receiving hole the adjustment of the lower strut in the extension range of motion is prevented;
a first pull tab positioned at the first end of the first portion of the flex lock to facilitate an association and a disassociation of the first push button with the first receiving hole; and
a second pull tab positioned at the first end of the second portion of the flex lock to facilitate an association and a disassociation of the second push button with the second receiving hole.
5. The flex lock system of claim 4 , wherein the first and the second flex lock portions comprise an elastomeric material.
