Abstract

A fastener member for mechanical affixation to a structure includes a base having first and second sides, a plurality of fastening elements integrally formed and extending from a first side of the base, and at least one affixation element extending from the second side of the base and arranged to mechanically affix to an attachment opening of a structure. A system includes a structure and a fastener member for mechanical affixation to the structure. A method includes affixing the fastener member to a structure.

Claims

1. An orthopedic device comprising a frame element, a brace component, and a fastener member for mechanical affixation of the brace component to the frame element, the fastener member including:

a base having first and second sides;

a plurality of hook fastening elements extending from a first side of the base; and

an affixation element extending from the second side of the base and arranged to mechanically affix to an attachment opening of the frame element, and selectively positioned along a plurality of locations of the attachment opening;

wherein the affixation element has a head defining a length dimension extending longer than a width of the attachment opening, and a stem carrying the head which passes through the attachment opening;

wherein the attachment opening is formed as an elongate slot such that the fastener member slides relative to peripheral walls surrounding the elongate slot along a length of the elongate slot;

wherein the fastener member is secured to the frame element in a secured configuration by rotating the fastener member such that the head of the fastener member is pressed against a first surface of the frame element beyond the peripheral walls of the attachment opening, and such that the second side of the fastener member is pressed against a second surface of the frame element;

wherein the fastener member is readjustable relative to the frame element from the secured configuration by rotating the fastener member so a length dimension of the head is parallel to a length of the attachment opening and relocating the fastener member along the plurality of locations of the attachment opening; and

wherein the brace component is arranged to connect to the frame element by the fastener member and includes loop material for interengaging the plurality of hook fastening elements of the fastener member, and is selected form the group consisting of a strap and padding.

2. The orthopedic device of claim 1, wherein the fastener member is arranged to rotate or linearly travel within a certain range of a length of the attachment opening.

3. The orthopedic device of claim 1, wherein an entirety of the base of the fastener member is arranged directly adjacent to the second surface of the frame element due to the stem carrying the head of the affixation element having a height corresponding to and the same as a thickness of the peripheral walls to assure that the second side of the fastener member is snugly secured without movement directly against the second surface of the frame element.

4. The orthopedic device of claim 1, wherein the frame element includes a recess formed about the peripheral wall defining the attachment opening, the affixation element arranged to be secured against and within the recess.

5. The orthopedic device of claim 4, wherein the recess corresponds in shape to the fastener member to retain the fastener member in place.

6. The orthopedic device of claim 5, wherein the recess is arranged in size to eliminate clearance of the head from the first surface of the frame element.

7. The orthopedic device of claim 1, wherein the fastener member is formed in a substantially flexible condition.

8. The orthopedic device of claim 1, wherein the length of the attachment opening is substantially longer than a length dimension of the head.

9. The orthopedic device of claim 1, wherein the fastener member is made from a polymeric material.

10. The orthopedic device of claim 1, wherein the hook fastener elements are secured to the base.
