UNITED STATES PATENT OFFICE SAFETY PIN Dante V. Bagnasco, Brooklyn, N. Y.

Application March 14, 1947, Serial N 0. 734,589 3 Claims. (01. 24-161) l This invention relates to a pin of the safety pin type which may be used either for utilitarian purposes or as an ornament.

It is an object of this-invention to provide a pin which, when in use, will lie flat against the body so as completely to conceal the pin, and which will not make an unsightly lump in the surface of the outer garments, and which will not be uncomfortable to the wearer even if he should sit upon it. It is a further object to provide a pin which may be readily opened, but which, when in the closed position, will remain closed against accidental opening.

It is a further object to provide a pin in which the pin portion will be completely concealed within the body portion so that the body portion may be used as an ornament. It is a further object to provide a pin which may be made of ornamental material such as plastic, and yet which will be inexpensive to manufacture and reliable and durable in use. 7

The invention accordingly comprises an article of manufacture possessing the features, properties and the relation of elements which will be exemplified in the article hereinafter described and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings, in which:

Fig. l is a perspective view of a pin embodying this invention. Fig. 2 is an enlarged fragmentary perspective of the clasp portion of the pin. Fig. 3 is a section on the line 33 of Fig. 1 showing the relation of the parts during the closing of the pin. Fig. 4 is a similar view when the pin is completely closed. Fig. 5 is a longitudinal view fragmentary central section showing the form of the clasp element. Fig. 6 is a view similar to Fig. 2 showing a modification of the device. Fig. 7 is a view similar to Fig. 5 of the modified form. Fig. 8 is a longitudinal section through the device of Fig. 1. Fig. 9 is a section on the line 99 of Fig. 8.

In the drawings, the numeral I0 comprises an elongated dished body portion affording a channel trough ll within which the pin portion may be concealed, which trough is bounded throughout its periphery by a ridge [2 which is made much heavier at both ends to carry the other portions of the device.

Mounted within this ridge at one end of the body is a shank portion l3 of a pin M. This shank portion is-embedded within a recess in the ridge in such a manner as to permit the pin to be substantially concealed within the trough when in the closed position, but to spring out-' wardly to the position shown in Fig. 1 during at tachment.

At the other end of-the body, and also embedded within an enlarged portion of the ridge i2 is the shank portion l6 of the catch IT. This catch has a spring portion [8 extending toward the center of the pin [4. This spring portion is formed with an obtrusion I9 shaped to receive the end portion of the pin when the latter is in closed position, and with laterally and downwardly extending flanges 20.

The shank of the catch member is embedded in the material of the ridge, but the ridge at this end of the pin is hollowed out to afford a chamber for the receipt of the spring portion of the catch as shown at 2| in Figs. 1, 2 and 5 and 2 la in Fig. 6. The upper surface of this hollowedout portion is cut away as at 22 at the center to accommodate the obtrusion l9, and to permit the end of pin [4 to enter, but the portion of the upper surface adjacent to the obtrusion bears against the upper face of the flanges 2!) when in a position of rest. The'springiness of the catch is sufiicient to permit the Spring member to be depressed sufiiciently to pass the free end of the pin [4 between the side flanges 20 and the upper surface of the hollowed-out portion, as will be seen from Fig. 3, but yet to permit the spring portion to spring back into place after the pin is inserted as shown at Fig. 4.

The inner edges of flanges 26 are bent away, as shown at 26a, from the surface of the interior of recess 2| so that, in opening the pin, the point may be slipped between the flange and the body to bend the clip inwardly to release the pin.

The construction shown in Figs. 6 and '7 is similar to that previously described except that the shank 23 of the catch is reversely bent down- In connection with this modification, there is also shown a slightly different form of the catch itself in that a side flange 26 is provided only upon one side of the spring member, while the reverse side is bent underneath the pin as shown at 21 in order more firmly to hold the pin when in its closed position. For some purposes it is desirable to have this portion 21 bent back closely adjacent to the flange 26 as shown at 28, close enough to resiliently retain the end of the pin 14 within the orifice 29 formed by the obtrusion 39 in the spring member. With this embodiment it will be seen that, in closing the pin, the pin point must first be pressed downwardly to pass between the flange 26 and the body, and then must be positively bent upwardly to pass through the passageway 28. In this latter position it is held in place until forcibly dislodged.

Since certain changes may be made in the, above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

I claim:

1. A pin comprising av body, a pin element attached at one end to one end of said body, spring-urged away from said body, flanges on the other end of said body extending inwardly toward each other, defining with said body a recess for the free end of the pin element, said flanges being stiff to resist bending under the strains imposed upon the pin element in use, and said flanges defining between their inner edges a slot, and a spring clip fixed within said recess having a free end extending across said slot and having an outwardly curved boss fitting within said recess, said clip being spring-held against the edges of said slot, said clip having on one gagement therewith, sufiiciently to permit thefree end of said pin element to pass below said spring arm and into said boss and whereby said spring arm when within said recess may be inserted between said curved end and said flange to depress the spring sufliciently topermit release of the pin.

2. A pin-comprising a body, apinelement attached at one end to one end of said body, spring.- urged away from said body, flanges on the other end of said body extending inwardly toward each other from the endand sides, defining with said body a recess for the free end of the pin element, said flanges being stiff to resist bending under the strains imposed upon the pin element in use, and said flanges defining between their inner edges and a slot, a spring clip fixed within saidrecess, having an arm extending toward said other end of said body by which the clip is at-- tached to said body, said clip having an outwardly curved boss in alignment with, and said clip being spring-held against, the edges of said slot, said clip having on one edge of said boss a spring arm curved away from the adjacent flange, whereby said spring arm may be depressed by said pin element, when in engagement therewith, sufiiciently to permit the free end of said pin element to pass below said spring arm and into said boss and whereby said spring arm when within said recess may be inserted between said curved end and said flange to depress the spring sufliciently to permit release of the pin.

3. A pin comprising a body, a pin element attached at one end to one end of said body, springurged away from said body, flanges on the other end of said body extending inwardly toward each other from the end and sides, defining with said body a recess for the free end of the pin element, said flanges being stifi to resist bending under the strains imposed upon the pin element in use, and said flanges defining between their inner edges and a slot, a spring clip fixed within said recess, having an arm extending toward said other end of said body by which the clip is attached to said body, said clip having an outwardly curved boss in alignment with said slot and having a flat surface on each side of said boss within the recess, spring-pressed outwardly against the inner faces of said flanges, the edge of said flat surface being curved away from the adjacent flange, whereby said spring arm may be depressed by said pin element, when in engagement therewith, suificiently to permit the free end of said pin element to pass below said spring arm, and into said boss and whereby said spring arm when within said recess may be inserted between said curved end and said flange to depress the spring sufficiently to permit release of the pin.
