TENSION (BOBBY) PIN
United States Patent 3837350
A spring type tension main body section in the form of a loop having one fastener arm or pin which carries a felted bobby roll with a hook at the very top and at the bottom is a hinge with a spring between the ends of the arm. The arm is hooked onto the main body section which is bent upon itself to form a depending torsion loop for receiving the hook on the end of the pin. The hook latches to the loop and locks the pin. The spring at the middle of the pin acts to tighten (pull) the hair as well as tension the springs on both sides of the pin and the springs of the body section can act to take strain off the middle spring arm or pin so it will not pull the scalp of the head.

1. A device for curling hair on the head of an individual comprising; a main body section in the form of an elongated substantially closed loop and a pin member supported by said body section for engaging said hair, said pin member having the inner end thereof pivotally secured to one end of said loop with said pin member being pivotally movable in a plane perpendicular to the plane of said body section and having a fastener means formed at the outer end thereof adapted to be detachably secured to the opposite end of a said loop, and said body section having spring means provided therein between said ends of the body section on the opposite sides of said loop whereby said body section is resiliently movable transversely.
2. A device as in claim 1, wherein said body section is formed of resilient metal wire and said spring means is a coil spring.
3. A device as in claim 1, wherein said pin member has spring means provided between the ends thereof enabling said pin member to be resiliently movable transversely.
4. A device as in claim 3, wherein said pin member is formed of resilient metal wire and said spring means is a coil spring.
5. A device as in claim 1, wherein said pin member comprises resilient means for engaging said hair.
6. A device as in claim 5, wherein said resilient means is a cylindrical flexible sleeve member mounted on said pin member and extending substantially the length thereof.

Description:
The present invention provides for improved safety and freedom from danger which exists with certain applications of conventional bobby pins, such as certain snap-on or squeeze-type, etc., bobby pins, which harm the scalp by applying excess tension, on the hair as a result of rolling too tightly in order to get the desired result or form.
It is still another object of the present invention to provide a bobby pin which conforms with the contour of the scalp so people can get a night's rest, since some people cannot sleep well with conventional bobby pins.
It is a further object of the present invention to provide a bobby pin for the Negro and some foreign people whose hair is thicker, coarser, but wooly, etc., and for use where the pin is in need to be a bit smaller and larger in various cases or requires more finger room, as some peoples hair is harder to control than others.
Other ways and means will be apparent to those skilled in the art from the following detailed description and claims when read in conjunction with the accompanying drawing, within:
FIG. 1 is an elevational view of a model of the pin as used with the broken lines inside of the pin representing the felt bobby pin roll.
FIG. 2 is an elevational view of the pin in open position with the felt arm hook off the loop.
FIG. 3 is the middle bobby pin roll supporting arm of the pin which has a spring section and a hinge section.
The embodied works of art of the present invention shown in FIGS. 1-3 of the drawing compose a tension bobby pin 16 formed of extended sections of wire 17 and 22, respectively, which can be heat treated in any conventional manner to impart resilience thereto. The tension pin 16 has a main body section 18 extending as a substantial closed loop with spring coils 19 and 19', respectively, formed between the ends thereof and straight upper arm actions 20 and 21 extending axially in opposite directions from the ends of the coil 19. The outer ends of each of the straight upper arm section 20, 21 extends downwardly and is bent upon itself to form a depending torsion spring loop 23. The lower side is formed of supporting arms 25 and 26 extending axially in opposite directions from ends of the coil 19', respectively.
FIG. 3 of the drawing shows the latch section as well as the spring hook and hinge which form the pivotally mounted bobby pin roll support arm, all formed of an extending action of wire 29 which can be heat treated in any conventional manner to impart resilience thereto. The hook section 27 and the spring section 28 are formed by bending a section of wire. The hinge section 24 is a conventional hinge element pivotally mounted between the ends of the main body section.
