Abstract

Claims (40)

1. A unitary hair clip for binding a bundle of hair, comprising:

a continuous unitary strip of flexible material having a first surface, a second surface opposite thereto, and a longitudinal centerline, the strip comprising:

an elastic midsection;

a first elongate strip portion with a first distal end extending along the longitudinal centerline from the elastic midsection, the first portion having a first width; and

a second loop portion with a second distal end extending along the longitudinal centerline from the elastic midsection opposite to the first portion, the second loop portion including a peripheral loop element formed by two lateral loop segments tapering laterally out wider from the elastic midsection, tapering laterally back in and meeting at the second distal end, and defining an aperture that is disposed about the longitudinal centerline and between the elastic midsection and the second distal end, the aperture having a second width that is greater than the first width of the first strip portion,

wherein the strip is movable between the initial open position and an in-use closed position, the elastic midsection biases the strip toward the open position and against the movement to the closed position, in the open position the first and second portions are separated so that the hair bundle can be inserted therebetween, and in the closed position the first and second portions are coupled together so that the hair bundle is gripped therebetween, wherein in the closed position the first portion is disposed through the aperture with the elastic midsection providing an expansive force binding the first distal end back against the second distal end to maintain the contiguous structure in the closed position,

wherein in the open position the first portion and the second portion extend in generally opposite directions away from the elastic midsection, and in the closed position the first portion is bent and torqued about the elastic midsection and passed through the aperture of the second portion with the first surface of the first distal end binding against the first surface of the second distal end to maintain the strip in the closed position, and

wherein in the closed position the hair bundle is routed under and against the second surface of one of the lateral loop segments of the second portion peripheral loop element, and at least partially out through the second portion aperture, over and against the second surface of the first portion, back through the second portion aperture, and under and against the second surface of the other one of the lateral loop segments of the second portion peripheral loop element.

2. The unitary hair clip of claim 1 , wherein, in the initial open state, the longitudinal centerline conforms generally to a U shape.

3. The unitary hair clip of claim 1 , wherein, in the initial open state, the longitudinal centerline conforms generally to an S shape.

4. The unitary hair clip of claim 3 , wherein in the initial open S-shaped position the first distal end of the first strip portion is curved, and in the in-use closed position, with the first portion bent and torqued about the elastic midsection, the first distal end of the first strip portion retains its curved shape from the initial open position.

5. The unitary hair clip of claim 1 , wherein the first portion conforms to a first curve from the first distal end to the elastic midsection, and the second portion conforms to a second curve that is substantially an inversion of the first curve from the second distal end to the elastic midsection.

6. The unitary hair clip of claim 1 , wherein the first portion is subdivided as a plurality of parallel members.

7. The unitary hair clip of claim 1 , wherein the hair clip in the closed position has a generally concave contour to conform generally to a human head.

8. The unitary hair clip of claim 1 , further including an internal leaf spring disposed entirely within the elastic midsection.

9. The unitary hair clip of claim 1 , wherein the hair clip is operable to move between the open position to the closed position,

wherein the hair clip is closed by:

bending the first portion about the elastic midsection towards the second portion;

accentuating the bend of the first portion to place the first distal end through the aperture;

releasing the bend to extend the first distal end through the aperture, the release of the bend further bringing the first surface of the first distal end into pressured contact with the first surface of the second distal end, the pressured contact achieving a frictional force of sufficient magnitude to hold the first distal end against the second distal end; and

wherein the hair clip is opened by:

depressing the first portion through the aperture to bend the first portion about the elastic midsection and separate the first distal end from the second distal end;

accentuating the bend of the first portion to place the first distal end within the aperture; and

withdrawing the first distal end from the aperture and releasing the first portion.

10. The unitary hair clip of claim 1 , wherein the aperture has a length greater than the second width.

11. The unitary hair clip of claim 1 , wherein the first distal end is slidable against the second distal end, with the first portion having a length that is long enough that is can be deflected and still bind the hair bundle against the second portion, slide against the second distal end, and maintain binding contact with the second distal end.

12. The unitary hair clip of claim 1 , wherein the second surface of the second loop portion includes a plurality of gripping elements disposed peripherally around the aperture.

13. The unitary hair clip of claim 1 , wherein a spring element is embedded internally within the elastic midsection.

14. The unitary hair clip of claim 13 , wherein the spring element is a plastic spring element.

15. A method of temporarily binding a bundle of hair, the method including:

providing a hair clip comprising a continuous strip of flexible material having a first surface, a second surface, a longitudinal center line, an elastic midsection, a first portion with a first distal end extending along the longitudinal centerline from the elastic midsection and with a first width, a second portion with a second distal end extending along the longitudinal centerline from the elastic midsection opposite to the first portion, the second portion defining an aperture disposed about the longitudinal centerline and between the elastic midsection and the second distal end, the aperture having a second width greater than the first width and a length greater than the second width, the elastic midsection biasing the contiguous flexible strip toward an initial open position and against movement to an in-use closed position, in the open position the first and second portions are separated so that the hair bundle can be inserted therebetween, and in the closed position the first and second portions are coupled together so that the hair bundle is gripped therebetween, the method comprising moving the hair clip from the initial open position to the in-use closed position by:

bending the first portion about the elastic midsection towards the second portion with the hair bundle between the first and second positions;

accentuating the bend of the first portion to place the first distal end through the aperture; and

releasing the bend to extend the first distal end along the aperture, the release of the bend further bringing the first surface of the first distal end into pressured contact with the first surface proximate to the second distal end, the pressured contact achieving a frictional force of sufficient magnitude to hold the first distal end against the second distal end with the hair bundle routed under and against the second surface of the second portion, at least partially out through the second portion aperture, over and against the second surface of the first portion, and in through the second portion aperture under and against the second surface of the second portion.

16. The method of claim 15 , further comprising moving the hair clip from the closed position back to the open position by:

depressing the first portion through the aperture to bend the first portion about the elastic midsection and separate the first distal end from the second distal end;

accentuating the bend of the first portion to place the first distal end within the aperture;

withdrawing the first distal end from the aperture and releasing the first portion; and

removing the hair bundle from between the first and second portions.

17. The method of temporarily binding a bundle of hair of claim 15 , wherein the step of providing further includes providing a spring element embedded internally within the elastic midsection.
