Safety pushpin

Claim 2

A safety pushpin that can concurrently serve as a clip, comprising, a head and pin extending from the central part of said head, said pushpin being housed within a casing comprising an upper shell having a shell top with a large-diameter hole surrounded by an inwardly extending flange and a lower shell having a bottom wall with a small-diameter hole in the center thereof; said head being larger in diameter than the distance across said flange of said large-diameter hole and said pin being passable through said small-diameter hole in the bottom wall of said lower shell, and further characterized in that an oblique space spread out radially toward both upper and lower ends is provided at a suitable part in the juncture of said upper and lower shells, both of said upper and lower shells being joined together swingable relative to each other so that said oblique space may be closed, and an elastic material is provided between said upper and lower shells to normally keep said oblique space open.

Claim 3

The safety pushpin as set forth in claim 1, wherein a suitable weak elastic means is interposed between the head of the pushpin and the bottom wall of said lower shell to push up said head so that the upper side thereof is pressed against and checked by the underside of the inwardly flanged edge of said large-diameter hole.

Claim 4

The safety pushpin as set forth in claim 1, wherein said lower shell is made from an elastic material and a suitable part or parts of the bottom wall is/are cut and raised up to form an elastic flap or flaps to give an elastic action to the head of the pushpin.

Claim 5

The safety pushpin as set forth in claim 2, wherein said elastic means is a coil spring.

Claim 6

The safety pushpin as set forth in claim 2, wherein said elastic means is urethane foam.

Claim 7

The safety pushpin as set forth in claim 1, wherein a permanent magnet is provided at the bottom of said lower shell.

Claim 8

The safety pushpin as set forth in claim 1, wherein a non-skid means is provided at the parallel faces in the juncture of said upper and lower shells.

Claim 9

A safety pushpin comprising, a head having a top and an underside; a pin having an upper end secured to said underside of said head and a lower pointed end; a casing having a cavity therein for housing said pin and said head, said casing having a large diameter hole in the top thereof and a small diameter hole in the bottom thereof; an annular inwardly extending flange extending around said large diameter hole, said pin and head being within said cavity with said top of said head being presented towards said annular flange and with said pointed end of said pin in registered alignment with said small diameter hole, said head being sized larger than said annular flange so that said annular flange will limit upward movement of said head at an upper position wherein said upper surface of said head is substantially co-planar with said top of said casing, an elastic body within said cavity for engaging said head and yieldably urging said head into engagement with said annular rim, said head being exposed to the exterior of said casing through said large diameter hole whereby said head can be manually pressed downwardly within said casing to a position wherein said pointed end of said pin protrudes through said small diameter hole, said casing being formed from shells which are split vertically.

Claim 10

A safety pushpin comprising, a head having a top and an underside; a pin having an upper end secured to said underside of said head and a lower pointed end; a casing having a cavity therein for housing said pin and said head, said casing having a large diameter hole in the top thereof and a small diameter hole in the bottom thereof; an annular inwardly extending flange extending around said large diameter hole, said pin and head being within said cavity with said top of said head being presented towards said annular flange and with said pointed end of said pin in registered alignment with said small diameter hole, said head being sized larger than said annular flange so that said annular flange will limit upward movement of said head at an upper position wherein said upper surface of said head is substantially co-planar with said top of said casing, an elastic body within said cavity for engaging said head and yieldably urging said head into engagement with said annular rim, said head being exposed to the exterior of said casing through said large diameter hole whereby said head can be manually pressed downwardly within said casing to a position wherein said pointed end of said pin protrudes through said small diameter hole, said casing being formed from shells which are split vertically.

Claim 11

A safety pushpin comprising, a head having a top and an underside; a pin having an upper end secured to said underside of said head and a lower pointed end; a casing having a cavity therein for housing said pin and said head, said casing having a large diameter hole in the top thereof and a small diameter hole in the bottom thereof; an annular inwardly extending flange extending around said large diameter hole, said pin and head being within said cavity with said top of said head being presented towards said annular flange and with said pointed end of said pin in registered alignment with said small diameter hole, said head being sized larger than said annular flange so that said annular flange will limit upward movement of said head at the upper position wherein said upper surface of said head is substantially co-planar with said top of said casing, an elastic body within said cavity for engaging said head and yieldably urging said head into engagement with said annular rim, said head being exposed to the exterior of said casing through said large diameter hole whereby said head can be manually pressed downwardly within said casing to a position wherein said pointed end of said pin protrudes through said small diameter hole, said elastic body being urethane foam.

Claim 12

A safety pushpin comprising, a head having a top and an underside; a pin having an upper end secured to said underside of said head and a lower pointed end; a casing having a cavity therein for housing said pin and said head, said casing having a large diameter hole in the top thereof and a small diameter hole in the bottom thereof; an annular inwardly extending flange extending around said large diameter hole, said pin and head being within said cavity with said top of said head being presented towards said annular flange and with said pointed end of said pin in registered alignment with said small diameter hole, said head being sized larger than said annular flange so that said annular flange will limit upward movement of said head at the upper position wherein said upper surface of said head is substantially co-planar with said top of said casing, an elastic body within said cavity for engaging said head and yieldably urging said head into engagement with said annular rim, said head being exposed to the exterior of said casing through said large diameter hole whereby said head can be manually pressed downwardly within said casing to a position wherein said pointed end of said pin protrudes through said small diameter hole, said elastic body being urethane foam.
