Description

Feb. 28, 1956 C. R. COCHRAN PIN CURL CLIP Filed July '7, 1954 Char/es R. Cochran INVENTOR.
BY M M F M United States Patent PIN CURL CLIP Charles R. Cochran, Chicago, Ill.
Application July 7, 1954, Serial No. 441,715
Claims. (Cl. 132-52) This invention relates to hairdressing implements and more particularly to a novel pin curl clip.
The primary object of the present invention resides in the provision of a clip which because of its unique and novel construction automatically distributes an even pressure across the entire width of the pin curl or strand of hair of any given thickness up to the load capacity of the clip thereby maintaining the pin curl or strand of hair with the maximum security in any desired position over the required period of time for forming the desired wave.
A further object of the invention resides in the pro vision of a pin curl clip which does not have a handle so as to enable the clip to be constructed as short as possible to have the greatest effective length thereby enabling pin curls to be formed very close together.
Still further objects and features of this invention reside in the provision of a pin curl clip that is strong and durable, simple in construction and manufacture, which may be formed of various readily available material and which is inexpensive to produce thereby permitting wide distribution and utilization.
These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by these pin curl clips, preferred embodiments of which have been illustrated in the accompanying drawings by way of example only, wherein:
Figure 1 is a perspective view of a pin curl clip employing the concepts of the present invention shown in a closed position;
Figure 2 is aplan view of the blank from which the pin curl clip is bent;
Figure 3 is a sectional view as taken along the plane of line 33 in Figure 1 illustrating the pin curl clip in a closed position;
Figure 4 is a sectional view similar to that of Figure 3 but illustrating the pin curl clip engaging a strand of hair;
Figure 5 is a perspective View of a modified form of pin curl clip;
Figure 6 is a plan view showing the blank from which the pin curl clip of Figure 5 is formed; and
Figure 7 is a sectional view as taken along the plane of line 77 of Figure 5 showing the pin curl clip in a closed position;
With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, and with initial reference to the form of the invention shown in Figures 1 through 4, it will be noted that herein there is disclosed a pin curl clip having a lower clip portion 12 and an upper clip portion 14. The upper and lower clip portions are joined by a substantially U-shaped portion 16 which resiliently urges the arcuate end 18 of the upper clip portion 14 into resilient engagement with the lower clip portion 12 at a point remote from the U-shaped portion 16.
The lower clip portion 12 is bifurcated to form prongs 20 and 22 which are joined by a cross bar 24 adjacent the U-shaped portion 16. The upper clip portion 14 has a central aperture 26 therein and a leaf 28 is spaced from the other portions of the upper clip portion 14 by the aperture 26, the aperture 26 being of greater dimension than that of the leaf 28. A suitable aperture 30 is formed in the curved portion 18.
In use, a strand of hair as is shown in Figure 4 and designated by reference numeral 32 is introduced under the leaf 28 and between the prongs 20 and 22 and the curved portion 18. The leaf 28 which extends parallel to the prongs 20 and 22 exert an even pressure throughout the length of the strand 32. The apertures 26 and 30 will assure proper ventilation of the strand of hair 32. k
It is noted that the leaf 28 extends through and'beyond the U-shaped portion 16 forming means for readily and easily removing the clip from the hair.
Referring now to the form of the invention as is shown in Figure 5 it will be noted that the lower clip portion in this form of the invention is substantially similar to the form of the invention shown in Figures 1 through 4 and includes prongs 40 and 42 which are joined by a cross bar 44, the lower clip portion 46 being integrally connected by means of a U-shaped portion 48 with the upper clip portion 50. The upper clip portion 50 includes a pair of leaves 52 and 54 on either side thereof and spaced therefrom but joined to the arcuate portion 56 which is apertured as at 58.
The strand of hair is inserted between the prongs 40 and 42 and the curvilinear portion 56 so that the leaves 52 and 54 which extend parallel to the prongs 40 and 42 can exert an even pressure throughout the dimensions of the strand of hair. The space between the leaves 52 and 54 and the central portion of the upper clip portion 50 as at 60 and 62 assures ventilation for the strand of hair as does the aperture 58.
From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
What is claimed as new is as follows:
1. A pin curl clip formed integrally of a resilient material comprising upper and lower clip portions joined by an interconnecting U-shaped portion urging a portion of said upper clip portion remote from said U-shaped portion into resilient engagement with said lower clip portion, said upper clip portion having at least one leaf extending substantially parallel with said lower clip portion, said leaf extending beyond said U-shaped portion.
2. A pin curl clip formed integrally of a resilient material comprising upper and lower clip portions joined by an interconnecting U-shaped portion urging a portion of said upper clip portion remote from said U.-shaped portion into resilient engagement with said lower clip portion, said upper clip portion having at least one leaf extending substantially parallel with said lower ciip portion; said lower extending beyond and through said U-shaped portion.
3. A pin curl clip formed integrally of a resilient material comprising upper and lower clip portions joined by an interconnecting U-shaped portion urging a portion of said upper clip portion remote from said U-shaped portion into resilient engagement with said lower clip portion, said upper clip portion having at least one leaf extending substantially parallel with said lower clip portion; said lower clip portion being bifurcated to form prongs, said prongs being joined by a cross bar, said prongs extending beyond said upper clip portion, said end of said upper clip portion Patented Feb. 28,' 1956- remote from said U-slrapedportion being apertured and upwardly curved.
4. A pin curl clip formed integrally of a resilient material comprising upper and lower clip portions joined by an interconnecting U-shaped portion urging a portion of said upper: clipportion remote from said U-shaped portion into resilient engagement With said lower clip portion, said upperclip portion having at least one leaf extending substanti-ally' parallel with said lower clip portion, said leaf extending beyond and through said U-shaped portion, said lower clip portion being bifurcated to form prongs, said. prongs being joined by a cross bar, said prongs extending beyond said upper clip portion, said end of said upper clip portion remote from said U-shaped portion being apertured and upwardly curved.
5-; Apin-curl clip formed integrally of a resilient material comprising upper and lower clip portions joined by ail-interconnecting U-shaped portion urging a portion of said upper clip portion remote from said U-shaped portion into resilient engagement with said lower clip portion, said upper clip portion having a leaf on either side of and outwardly spaced from said upper clip portion, each leaf extending substantially parallel with and beyond said lower clip portion, said lower clip portion being bifurcated to form prongs, said prongs being joined by a cross bar, said prongs extending beyond said upper clip portion, said end of said upper clip portion remote from said U-shaped 10 portion being apertured and upwardly curved.
