United States Patent O HAIR CURL CLIP Armand Braga, South Pasadena, Calif.

Application March 4, 1955, Serial No. 492,269

10 Claims. (Cl. 132-50) This invention relates to a hair curl clip.

One of the principal objects of this invention is to provide an improved clip for maintaining a hair curl such as a pin curl in secure coiled position.

Another object of Vthis invention is to provide a curl clip of new construction whereby the cooperation of parts causes less wear and results in a longer period of use.

Another object of this invention is to provide a curl clip necessitating only slight finger tip pressure to open said clip.

Still another object of this invention is to provide a clip that will automatically return to closed position when pressure is released, thus eliminating the necessity of using both hands in operating the clip, and allowing one hand to be `free to form the curl.

Another object of this invention is to provide a clip of such character that it has greater ease of assembly.

Another object of this invention is to construct a clip that is produced by a stamp press or a like operation and thus is more economical in cost.

Other objects and advantages of the invention will become apparent during the course of the following description.

In the accompanying drawing, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure l is a top elevational view of a curl clip embodying this invention;

Figure 2 is a side elevational exploded view of the clip;

Figure 3 is a cross section of the clip taken on line 3-3 of Figure l;

Figure 4 is a central longitudinal cross section of the clip in open position;

Figure 5 is a modied form of said curl clip.

Referring to the drawing, reference numeral designates a curl clip made of spring metal or other suitable resilient material. The clip 10 comprises two elongated flat spring strips 11 and 12 and adapted to be held in a superimposed relationship by a yoke 13.

The yoke 13 consists of a substantially flat base 14, generally T shape in plan, having a rectangular aperture 15, as best shown in Figure l, located in the head of the T identified as the rearward end 16 of the base 14, a pair of parallel side walls 17 and 18 rising vertically from base 14 along its forward end 19, forming a channel by their inner walls 20 and 21 to receive the spring strip 12.

As best shown in Figure l, ears 22 and 23 are cut inwardly from the central region of the walls 17 and18, respectively, one end of each ear remaining integral with side walls 17 and 18. The ears 22 and 23 extend toward each other to cooperatively provide a seat for holding the upper spring strip 11 in alignment with the lower strip 12 and further acting as a fulcrum for the upper spring strip 11.

The spring strip 11, which is of uniform thickness, is formed at its forward end 24 with an upwardly extending tip 25 angular to the general horizontal plane of the strip 2,764,987 yFatosnted Oct. Z, 1956 11. Adjacent the rearward end 26 of -tip 25, and integral therewith is an angle 27 rising to meet the horizontal plane of strip 11. Formed in the central horizontal plane of spring strip 11 is a attened indentation 28. Adjacent the rearward end 31 of strip 11 a rising spring loop 32 is formed, with its terminal end 32 positioned lower than the horizontal plane of strip 11. A dihedral angle 33 is interposed between the spring loop andthe straight section at the rearward end 31 of spring strip 11 and is positioned between ears 22 and 23 of walls 17 and 18.

The spring strip 12 'is also of uniform thickness and extends in a generally horizontal plane. It comprises a downwardly 'extending tip 3S, best shown in Figure 2, adjacent the rearward end 36 which is inserted inthe aperture 15 of the yoke, to maintain the lower strip 12 in slidable alignment within the yoke. Extending upwardly from the top plane surface 37 of the strip 12, are two dimples 38 and 39 between which is provided a seat 40. It is recognized that the seat 40 may be formed between two beads extending across the top plane surface of the strip 12, instead of dimples. The lseat 40 which is in the form of a hollow or groove should be wide enoughto accommodate the end portion 32 of spring loop 32. The strip 12 is bent downwardly at 41, then inclined upwardly at angle 42 to merge into the general horizontal plane of the spring strip 12 at bend 43, providing an offset to accommodate a gathering of hair between the strips 11 and 12.

In the modification illustrated in Figure 5 of the drawing, the upper spring strip 11 is formed of an elongated flat spring strip of uniform thickness and the plane surface 44 is unbroken from its forward end 45 to the dihedral angle 33 corresponding to the angle 33 described above.

Further, in this modified form, the lower spring strip 12' is formed of an elongated llat spring of uniform thickness, and the indentation and beads 38 and 39 are absent to produce an uninterrupted plane surface from its forward end 46 to its rearward end 47.

In this modification, the two spring strips when in closed position contact at the forward ends 45 and 46. The base 14 may be omitted if the yoke side walls are formed integral with the lower strip 12.

It is believed from the foregoing that the manner of assembling the three major parts described above and their co-acting relationship has been made apparent. To summarize: The rear end portion of the lower strip 12 slidably rests upon the upper surface of the horizontal portion of the yoke 13 with the tip 35 of the strip 12 protruding into aperture 15 of the yoke, the forward and rearward edges of which aperture provide stops limiting the relative longitudinal movement between strip 12 and yoke 13. A certain amount of sliding action is necessary to accommodate the thrust of the end 32 of spring 32. The upper strip 11 is superimposed over the lower strip 12 with the dihedral angle of the upper strip below the ears 22 and 23 of the yoke and the extreme end 32 of the spring loop engaging in the hollow or groove provided bythe beads 38 and 39.

In thus assembling the parts the spring loop 32 is contracted from the open position illustrated in Figure 3 to the compressed position shown in Figure'4. Asthe result of the end 32' bearing upon the sea't the spring loop exerts an upward thrust in a clockwise direction, as viewed in Figure 4, on the strip 11 against ears 22 and 23 functioning as a fulcrum and the opposing force exerted upwardlyagainst the fulcrum and downwardly against the seatinthe lower strip causing the two strips to be yieldably pressed together.

In order to spreadthe strips 11 and 12 apart to receive a substantially flat curl of hair, it is merely necessary to 3 squeeze together the spring loop 32 and the yoke 13. This is done by exerting opposed digital pressure of the thumb and rst iinger of the operator. Such pressure results in a counterclockwise thrust of the upper strip around the fulcrum provided by the ears, and the lower strip is prevented from following the angular elevation of the upper strip by reason of the pressure exerted downwardly by the end of the spring loop against the lower strip which maintains the lower strip in parallel contact with the upper face of the yoke. It will be clear that a slight longitudinal shifting of the lower strip within the yoke necessarily follows the action of the lower end of the spring loop because this loop is contracted under tension when the loop and yoke are squeezed together.

lkelease of the pressure upon loop and yoke permits the spring tension to return the upper and lower strips into contact or as nearly in contact as is permitted by the bulk of the hair curl engaged. Normally the curl being clamped 1s of a spiral or helical type, the radial surfaces are engaged by the clip rather than the circumferential surfaces, and the indentation 28 in the upper strip will be located in the center of the spiral or helical curl to retain separated the convolutions thereof.

In the modified form shown in Figure 5 the primary action of the respective parts and their cooperation is substantially the same as that already described, except that the lower end of the spring loop is free to slidably engage upon the upper surface of the lower strip without confinement of beads, and there is not necessarily any longitudinal sliding of the lower strip in the yoke. In such modification the aperture need be only large enough to receive the downturned end 36 of the lower strip without providing for any longitudinal movement in the aperture.

While the instant invention has been shown and described herein in what is conceived to be a practical embodiment, it is recognized that departures may be made therefrom within the scope of the invention, which is, therefore not to be limited to the details shown and described but is to be accorded the full scope of the claims.
