Jay. 2 /4 /3 /Z/f I llIlllllllIIl/llll/l Patented Jan. 19, 1937 UNITED STATES PATENT GFFICE 2 claims.
This invention relates to safety pins and comprehends an improvement therein by virtue of which the free end of the piercing leg isA more securely retained in the head of the pin and locked against displacement by strains and stresses exerted lengthwise of the pin.
It has been observed that the common forms of safety pins are open to the objection that a pull exerted outwardly on the opposite ends thereof tends to displace the free end of the piercing leg from its engaged position from within the head of the pin.
In order to overcome this objectionable feature, the present invention includes means provided respectively on the head of the pin and adjacent the free end of the piercing leg lthereof, which means are readily interlocked and are maintained in said interlocked relation by the inherent resiliency of the piercing leg.
More specifically, the invention resides in the provision of a right angularly disposed shoulder at or adjacent the free terminal of the piercing leg of the safety pin and a complementary keeper shoulder formed on the head of the pin with which the first mentioned shoulder engages when the free terminal of the piercing leg is positioned within the head.
Other objects of the invention are to provide an improved safety pin for the purpose set forth which is not unduly complicated in construction, adds little, if any, to the cost of production of the pin and which does not complicate the operations of engaging and disengaging the pin from the article to be pinned thereby.
With the above and other objects in view, reference is now made to the following specication and accompanying drawing in which there is disclosed, by wa-y of example, several preferred embodiments of the invention, while the appended claims cover variations and modifications which fall Within the scope of the invention.
In the drawing:
Fig. 1 is a side View of a safety pin constructed in accordance with one form of the invention and illustrating the head of the pin in section.
Fig. 2 is a similar view of a modified form of the invention.
Fig. 3 is a similar View of a further modification.
Referring to the drawing by characters of reference, the safety pin in the several modifications illustrated includes the usual xed leg A and movable piercing leg B which are commonly constructed from a single length of resilient wire,
(Cil. 24--156) the legs being joined together by a coil C and the fixed leg A having secured to the free end thereof the head D, the inner end edges of which are disposed substantially flush with each other and approximately at a right angle to the axis of the legs of the pin so as to provide edges prependicular to any strain exerted by material against the head of the pin. This avoids any tendency of the material to spread the portions of the head apart and effect release of the locking feature of the pin which is hereinafter set forth.
In the form of the invention illustrated in Fig. 1, the free end portion of the piercing leg B is provided with a right angularly disposed offset 5 providing a locking shoulder 6, the offset 5 being joined to the pointed terminal 'I by an inclined portion 8. The head D in this instance, is formed with an aperture 9 adapted to receive the offset portions 5 and 8 and one end Wall III of the aperture 9 constitutes a complementary shoulder with which the shoulder 6 of the right angular oiset 5 is adapted to engage when the free end of the piercing leg B is positioned in the head D. It will be observed that due to the inherent resiliency of the leg B that a tension is exerted to retain the locking shoulders in engaged relation and obviously any strains or stresses longitudinally of the pin by a pull exerted outwardly on the opposite ends of the pin will be resisted by the interengagement of the shoulders 6 and I0. To disengage the free end of the piercing leg B from the head, the free end of said leg is depressed in the usual manner and disengaged from the head D. It has also been observed that the oiiset portion offers but slight impediment to the insertion of the piercing leg in the material to be pinned and the withdrawal of the same therefrom.
In the modified form of the invention illustrated in Fig. 2 of the drawing, the free end of the piercing leg B is provided with a right angularly disposed offset portion I I defining a shoulder I2 and the remaining pointed extremity I3 extends inwardly at an angle to the portion II and to the access of the piercing leg B. In this form of the invention, the head D is provided with an aperture I4, one end wall I5 of which defines a complementary shoulder with which the shoulder I2 of the portion II engages. In both forms of the invention disclosed, it will be observed that the pointed terminal of the piercing leg is covered and protected by the head structure D when the free end of the piercing leg is positioned within the head.
In the form of the invention illustrated in Fig. 3 of the drawing, the piercing leg B is provided with an outwardly directed right angularly disposed pointed terminal i6 which denes a shoulder l1. The head D in this instance is formed with an outwardly directed hollow boss I 8, the inner surface of one of the side walls of which defines a complementary shoulder I9 with which the shoulder I'I is adapted to engage. In this form of the invention, the pointed terminal I6 is completely enclosed and protected by the hollow boss I8.
What is claimed is:
1. In a safety pin including a fixed leg, a movable piercing leg and a head for sheathing the free end of the piercing leg, means provided on the free end portion of the piercing leg and on the head dening interengageable shoulders disposed approximately at a right angle toy the axis of the piercing leg of the pin and said head having its inner end edges disposed substantially ilush with each other and approximately at a right angle to the axis of the legs of the pin.
2. In a safety pin including a fixed leg, a movable piercing leg and a head having an outwardly directed hollow boss defining a tubular keeper having an axis disposed approximately at a right angle to the axis of the piercing leg, and an out- Wardly directed pointed *terminal `'disposed at approximately a right angle to the remainder of the piercing leg and adapted to engage Within the keeper boss.
