7 Claims.

This invention relates to pin curl clips adapted for use in holding spirally wound strands of hair, and has for an object the provision of a clip which is simple and inexpensive to manufacture.

Briefly, the present invention comprises a pair of members blanked and formed from thin sheet metal and pivotally connected intermediate their ends, the forward portions of the members being formed to receive and clamp a pin curl and the rearward portions of the members being formed for engagement by the fingers of the user to pivot the forward portions away from each other. One of the members is formed with offset portions 'for pvotal engagement in bearing recesses formed in the other member, and the two members are held in assembled relation by means of a resilient rubber band which encircles the forward portions of the members adjacent their point of pivotal engagement.

This invention embodies other novel features, details of construction'and arrangement of parts which are hereinafter set forth in the specification and claims, and illustrated in the accompanying drawing, wherein:

Fig. 1 is a perspective view illustrating a pin curl slip embodying features of the present invention.

Fig. 2 is a transverse sectional view taken along the line 22 of Fig. 1.

Fig. 3 is a perspective view illustrating a modified form of this invention.

Fig. 4 is a transverse sectional view taken along the line 4-4 of Fig. 3.

Fig. 5 is a perspective view illustrating another modified form of this invention.

Fig. 6 is a transverse sectional view taken along the .line 6--6 of Fig. 5.

Fig. 7 is a side elevational view illustrating another modified form of this invention in which the forward portion of the upper member of the clip is formed curvilinear.

Referring now to the drawing for a better understanding of the present invention and more particularly to Figs. 1 and 2 therein, the hair clip is shown as comprising an upper member 6 and a lower member I which are preferably blanked and formed from relatively thin, light weight sheet metal, such as aluminum. The upper member 6 is slit longitudinally along the lines -88 and then formed to provide a pair of arcuate bearing portions an and an intermediate portion ll. The lower member 7 is provided with a pair of ears l2-l2 which project upwardly in spaced parallel relation for pivotal engagement against the arcuate bearing portions formed on the upper member 6. The intermediate portion i I provided on the upper member -'6 is bowed dcwnwardly and disposed between the ears ilk-J2.

The forward ends of the members 6 and 1 are of gradually decreasing width to provideha ir clamping portions l3 and I4, respectively, adapted to be engaged against opposite sides of a pin curl. A resilient rubber band i6 ls mounted-around the hair clamping portions 13 and I 4 adjacent the bearing portions 9--9 and ears 12-42 to yieldably resist pivotal movement of the members 6 and :l. The rearward ends of the members 6 and 1 are disposed in spaced relation to provide finger engaging portions I! and IB adapted to be pressed toward each other to pivot the hair clamping portions It and 14 to their open position to receive a pin curl therebetween. The members 6 and l are formed with longitudinally extending beads 19 and 2|, respectively, to increase their resistance to bending loads.

It will be noted that the hair clip shown and described is relatively simple and inexpensive in construction and may readily be applied to or removed from a pin curl by merely pressing the finger engaging portions I1 and 18 toward each other. It will also be noted that the resilient rubber bandacts to hold the members 6 and -'l in assembled pivotal engagement and also serves as a guard to prevent entanglement of hair between the arcuate bearing portions 9-9 andears 12-12 during use of the clip.

Referring now to Figs. 3 and 4 in the drawings, a modified form of this invention is shownas comprising an upper member 26 and a lower member 21 blanked and formed from thin sheet metal, the upper member being provided with a hair clamping portion 28 and finger engaging portion 29, and the lower member being provided with a hair clamping portion 3! and finger engaging portion 32. The upper member is formed with an arcuate bearing portion 33 and withside flanges 34-34, and the lower member is formed with a pair of upturned ears 36-3B for pivotal engagement against the bearing portion 33. The side flanges 34-34 are disposed along theremote sides of the ears 36-36 to hold the member's-2'6 and 21 in alignment and to prevent displacement of the ears from the arcuate bearing portion 33. A resilient rubber band 3'! is engagedaround the inner ends of the hair clamping portions 28 and 3| of the members 26 and 2'! to yieldably resist opening of the clip and to secure the members in assembled .pivotal relation. This form of the illvention is otherwise similar to the formxheretcfore described and illustrated Figs. rand 2 in the drawing.

Figs. and 6 in the drawing illustrate another modified form of this invention in which the clip is shown as comprising an upper member 4| and lower member 42 blanked and formed from sheet metal. The upper member 4| is slit and formed intermediate its ends to provide a pair of arcuate pivot portions 43-43 and an arched bridge portion 44. The lower member 42 is slit and formed intermediate its ends to provide a pair of bearing portions 46-46 and an arched bridge portion 41. The members 4| and 42 are provided with hair clamping portions 48-4801. respectively, and with finger engaging portions 46-4900, respectively. A resilient rubber band 5! is mounted around the hair clamping portions 48-48a to hold the upper and lower members in assembled pivotal engagement and to yieldably resist opening of the clip. In this form of the invention the pivot portions 43-43 on the upper member are pivotally engaged against the bearing portions 46-46 on the lower member, and the arched bridge portion 41 is disposed between the pivot portions 43-43 to prevent lateral displacement of the members. This form of the invention is otherwise similar to the two forms heretofore described and illustrated in Figs. 1 to 4 in the drawings.

Fig. '7 in the drawing illustrates another modified form of this invention in which the clip is shown as comprising an upper member 56 pivotally engaged at 51 to a lower member 58, as heretofore shown and described in connection with the preceding forms. The forward end of the upper member 56 is formed with two bow portions 59 and 6| to coact with the forward end ofthe lower member 58 in clamping a pin curl. The members 56 and 58 are held in assembled pivotal engagement by means of a resilient rubber band 62, as heretofore described.

In the several forms of this invention, it will be-noted that the two members forming the clip are adapted to be simply and inexpensively blanked and former from thin sheet metal and engaged for pivotal movement by a resilient rubber band which also serves to yieldably resist opening movement of the members and to prevent entanglement of hair within the pivot joint.

While this invention has been shown in several forms, it is obvious to those skilled in the art that it is not so limited but is susceptible of various changes and modifications without departing from the spirit and scope of the claimed invention.
