Application May 10,1952, serial No. 287,186 f i' 1.01am. f (ol. 13a-50)'4 v This invention relates to improvements vin hair pins and has for one object to provide a type of hair pin especially'adaptf'dv for holding flat, circular curls commonly termed pin curls, as formed on a womans head. .11.1
A further object of my invention is to provide a hair pin especially adapted to be made of plastic material having suiiicient flexibility to be readilyopened by thefingers, for application to the curl so thatone does not need to use'ithe teeth or finger nails .to open it as is done with the well-known type of bobby pin. f
Another object of. my'invention is to lprovide a hair pin of the character described above employing an external rib fyorspacing the formed curl from the scalp to promote ventilation for drying of the curl and also to aid in positioning the pin on the head of the user.
Other objects and purposes of the invention will appear from time to time as the following description proceeds.
The hair pin of the present invention constitutes an improvement over the type of hair pin disclosed and claimed in my application, Serial Number 268,359, flled January 26, 1952, now Patent No. 2,599,447.
My invention is illustratedmore or less diagrammatically in the accompanying drawing,
A wherein Figure 1 is a plan view of a hair pin constructed in accordance with my invention;
Figure 2 is a side elevation of Figure 1; l
Figure 3 is a detailed section taken on line 3-3 of Figure 2;
Figure 4 is a plan view drawn to a smaller scale than the preceding figures and illustrating the manner in which my hair pin is applied to a circular or pin curl;
Figure 5 is a section taken generally on line 5-5 of Figure 4;
Figure 6 is an enlarged end view of the hair pin, showing the mannerin which the central rib aids in positioning the pin when gripped between the finger and thumb of the user.
Like parts are indicated by like characters throughout the specification and drawing.
Referring to Figures 1 and 2, I is the long leg of the hair pin. It is joined by a continuous loop 2 to a shortleg 3. In the form shown herein, the short leg 3 is inwardly depressed as at 4, toward the leg I, thus centrally reducing the width of the pocket formed between the loner and short legs. The outer or free end of the short leg terminates in a downwardly inclined portion 5, the end of which engages the long leg intermediate its ends. The arrangement is such that the long end extends considerably beyond the-endo! the short leg so-as tmpermit-the'y ngerof-'the user to exert pressure atwise relativeto'- thel long leg without contacting the enclofk the short leg. f
vThelong leg I is' tipped atl itsextr'emeiend with an, enlarged vtip to `prevent scratching ,or cutting of a womans scalp. The end of theshort leg 3 terminates in a slightly upturned portion to aid in applying the pin to the curl.
With .thelegs shaped as shown and described, the downwardly inclined portion 5 of theo-short leg deflnesa closed loop or pocket forthelhir andv the intermediate inwardly. depressedjfporftion IIV divides .thepocket Ithusformed into two' arcuately shaped areas indicated at A and 'B which are of substantially equal area.
As seen in Figure l, both the long and the short legs are wider at their looped ends v2 and taper gradually toward their free ends.
The features hereinabove set forth are broadly shown and described in my aforementioned Patent No. 2,599,447.
Referring now more particularly to the novel features of the present invention, the pin is preferably made of a single piece of molded plastic. The legs I and 3, together with the spring loop 2,
are formed with continuous, widened, substantially flat, inner body portions 9, I0 and I I which generally define the shape of the two areas A and B. A centrally disposed, outwardly extending rib I2 is formed integrally with the flattened l portion 9 of leg I and continues as an'arcuate rib I3 about the loop I0, and thence as a continuing rib I4 along the upper surface of the flattened body portion Il of the short leg 3.V As will be' seen in Figure 2, the bottom rib I2 is tapered in height toward the extreme end of the long leg I and the top rib I4 is tapered in height toward the extreme end of the short leg 3.
The rib portions l2, is and I4 vjusteoscriioed v serve to strengthen the pin against breakage and, in particular, to increase they tension on the spring loop effective to hold the two legs together when the device is in operation. This feature is of particular advantage where the pin is made of plastic material as it increases the strength of the pin without an undue increase in'weight or thickness of the body of the pin, particularly in the area of the spring loop 2.
A further advantage of the ribbed vconstruction is the arrangement whereby the lower rib I2 on the longer leg 4I serves to space the body of the pin, together with the curl, a substantial distance away from the scalp of the user, as
shown in Figure 5, when the pin is in use. rwith 3 the coils of a curl secured within the looped areas A and B. This permits a freer circulation of air between the scalp of the user and the curl to aid in drying the hair in its curled condition.
A still further advantage of the novel ribbed construction is the fact that the rib serves as a guide when holding the pin between the ngers so as to indicate to the user when the pin is in proper position 'as it is being applied to thel curl. This feature is particularly helpful in a device of this kind where so many of the curls are put up on the head by feel out of sight of the user. Even when a mirror can be used, it will be found more convenient to rely upon feel rather than sight for the proper applicationv of the pin to the curl. Figure 6 shows the manner in which `the rib serves as a guide when gripped between the finger and thumb of the user.
Although I `have shown and'described certain embodiments of my invention, it will be understood that I' do not wish to be limited to the exact construction shownand described, but that various changes and modifications may be made' without departing from the spirit and scope of the invention as dened in the appended claim.
I claim: l
In a hair pin comprising long and short legs: joinedat one end by a continuous spring loop, theshort leg beig spaced from the long leg for the major portion of its length, and having a Aterminal portion inwardly inclined toward the long leg, an intermediate portion of said 4 terminal portion being normally held against the long leg by the tension of the spring loop to maintain said major portion of the short leg in spaced relation with the long leg, the extreme end of said terminal portion of the short leg being bent outwardly away from the plane of the long leg, the long leg extending beyond the end of the short leg a distance to permit| iiatwise pressure of thefnger of the user upon said long leg without' contact with. the short leg, the combination of a, continuous rib formed integrally with and extending centrally along `the outer faces of said long leg, loop and short leg, the said legs, loop and rib being of sufficient flexibility to permit the legs to be `readily spread apart by the :lingers of the user, said rib beingfrof maximum height adjacent the loop and tapering in height towards theA free ends of the long and short legs, said hairpin beingmade of molded plastic material.
