Definitions

  • the present invention relates to fasteners, and particularly to a safety pin with an arcuate pin bar.
  • the safety pin was first developed in the 1840's to solve the problem of pins becoming dislodged from the fabrics that they were supposed to secure.
  • the modern safety pin 10 is formed from a length of pin wire wrapped into a single coil 12, in essence forming a torsion spring.
  • One end of the wire has a sharp point 14 for piercing the material to be secured, this leg of the pin 10 often being referred to as the pin bar 16.
  • the opposite end of the pin wire has a shield 18 or catch attached thereto.
  • the shield 18 is formed with a convex outer side and a concave inner side throughout its length, being bent into a substantially U-shape.
  • the leg of the pin to which the shield 18 is attached is often referred to as the stationary bar 20.
  • a retainer or keeper 22 extends from the stationary bar into the center of the groove 24 formed by the shield 18, thereby preventing the pin bar 16 from being accidentally dislodged from the shield 18.
  • the pin bar 16 In order to fasten the pin 10, the pin bar 16 must be inserted into the shield 18 through a channel on one or the other side of the retainer 22, which acts as a guide for the pin bar 16, until the pin bar 16 becomes lodged in the center of the shield 18 directly opposed to the retainer 22. Similarly, to unfasten the pin 10, the pin bar 16 must be moved into a channel on either side of the retainer 22.
  • the conventional safety pin solved the problem of pins slipping out of the materials they joined together
  • the conventional safety pin does have some drawbacks.
  • the thin stationary bar can be difficult to grip firmly, having a tendency to roll or rotate between the fingers while trying to manipulate the pointed end through the material.
  • the material may be so thick that a considerable amount of finger strength is required to bend the pin bar far enough to insert the pointed end into the shield, and in some cases, it may not be possible to secure the pin bar to the shield without withdrawing the pin from the material and re-inserting the pin through a thinner portion of the materials.
  • the safety pin includes a torsion spring coil.
  • the torsion spring coil has a stationary bar and a pin bar extending from opposite ends.
  • the pin bar is arcuate and has a pointed end.
  • the safety pin further includes a shield attached to the stationary bar.
  • the shield extends at an angle relative to the stationary bar and defines a groove.
  • the pin bar is adapted for insertion through a material to be secured.
  • the pin bar is compressed toward the stationary bar and secured in the groove defined by the shield.
  • This disclosure is additionally directed to a safety pin.
  • the safety pin includes a torsion spring coil.
  • the torsion spring coil has a stationary bar and a pin bar extending from opposite ends.
  • the pin bar is arcuate and has a pointed end.
  • the stationary bar has an end bent backward at an angle.
  • the safety pin also includes a shield attached to the angled end of the stationary bar.
  • the shield extends at an angle relative to the stationary bar and defines a groove.
  • the pin bar is adapted for insertion through a material to be secured. The pin bar is compressed toward the stationary bar and secured in the groove defined by the shield.
  • the disclosure is further directed to a safety pin.
  • the safety pin includes a torsion spring coil.
  • the torsion spring coil has a fin and a pin bar extending from opposite ends of the coil.
  • the pin bar is arcuate and has a pointed end.
  • the safety pin additionally includes a shield attached to the fin.
  • the shield extends at an angle relative to the fin and defines a groove.
  • the pin bar is adapted for insertion through a material to be secured. The pin bar is compressed toward the fin and secured in the groove defined by the shield.
  • Fig. 1 is a front view of a first embodiment of a safety pin with an arcuate pin bar according to the present invention.
  • Fig. 2 is a front view of a second embodiment of a safety pin with an arcuate pin bar according to the present invention.
  • Fig. 3 is front view of a third embodiment of a safety pin with an arcuate pin bar according to the present invention.

  • Fig. 5 is a perspective view of a conventional safety pin according to the prior art. Similar reference characters denote corresponding features consistently throughout the attached drawings.
  • the safety pin with an arcuate pin bar is formed from pin wire bent in the middle to form a coil having a stationary bar extending from one end of the coil and a pin bar with a pointed end extending from the opposite end of the coil.
  • the pin bar is arcuate, or formed with an arch.
  • the stationary bar has a shield attached thereto, the end of the stationary bar being bent backward or the shield being attached to the end of the stationary bar so that the shield extends at an angle complementary to the curvature of the pin bar.
  • the stationary bar may have a textured or roughened fin formed thereon, and may have linear inner and outer edges, a straight inner edge and convex outer edge, or a concave inner edge and convex outer edge.
  • the arcuate pin bar allows for easier insertion of the pointed end through thickened material by rotation of the pin bar to a convenient angle for insertion through the material.
  • the fin may be made from metal or plastic, as may the shield.
  • the pin may be made from stainless steel in order to be used for surgical purposes.
  • the fin may be thick, or may be thin for savings in material costs.
  • the fin is textured, serrated, roughened, or coated with spray weld to render the fin easier to grasp and less prone to slip through the fingers.
  • the stationary bar and fin may be formed in various arcuate shapes, both to increase the gripping area and to allow for fastening thick material together.
  • the present invention is a safety pin with an arcuate pin bar.
  • a first embodiment of the safety pin 30 is made from pin wire bent in the middle to form a coil 32, in essence forming a torsion spring.
  • the safety pin 30 has an arcuate pin bar 34 having a sharp, pointed end 36 for piercing the material to be secured.
  • the safety pin 30 has a linear stationary bar 38 having a shield 40 attached thereto.

  • the safely pin 30 has a retainer 42 extending from the stationary bar 38 into the groove 44 formed by the shield 40.
  • the pin bar 34 In order to fasten the pin 30, the pin bar 34 must be compressed towards the stationary bar 38 and inserted into the shield 40 through a channel on one or the other side of the retainer 42, which acts as a guide for the pin bar 34, until the pin bar 34 becomes lodged in the center of the groove 44 defined by the shield 40 directly opposing the retainer 42. Similarly, to unfasten the pin 30, the pin bar 34 must be moved into a channel on either side of the retainer 42.
  • the radius of curvature of the pin bar 34 may vary, depending upon the length of the pin bar 34.
  • An exemplary dimension may be a radius of curvature of about two inches for a pin bar 34 having a length of about 1 3/4".
  • the angle of the shield 40 is complementary to the curvature of the pin bar 34 to increase the segment of the pin bar 34 that bears against the shield 40 due to the torsion applied by the coil 32.
  • the safety pin 30 may be made entirely from metal, such as stainless steel, or a portion of the safety pin 30, such as the shield 40 and/or the stationary bar 38 may be made from, or coated with, a plastic material, such as nylon.
  • Fig. 2 shows a second embodiment of the safety pin, designated as 50 in the drawing.

  • the fin 52 may be substantially flat and thin, i.e., less than or equal to the diameter of the pin bar 34, or may have any desired thickness.
  • the fin 52 may envelop the stationary bar 38, extend from the stationary bar 38, or be used in lieu of the conventional stationary bar 38, with only a portion of the stationary bar leg of the coil 32 extending into the fin 52.
  • the fin 52 may be made from metal or plastic, and has a textured or roughened surface to improve gripping of the fin 52.
  • the textured surface may be formed in any conventional manner, e.g., by milling or grinding, by applying a coating such as spray weld, by molding, calendaring, extrusion, or other manufacturing processes in the case of plastics, etc.
  • the shield 54 is attached to the end of the fin 52 at an angle, similar to that described for attaching the shield 54 to stationary bar 38 above.
  • the outer surface of the shield 54 may also be textured or roughened to make the shield 54 easy to grasp.
  • a retainer 56 extends into the groove formed by shield 54 in the manner described above.
  • the fin 52 has a substantially linear inner edge 58 and a substantially linear outer edge 60.
  • Fig. 3 shows a third embodiment of a safety pin, designated as 70 in the drawings.
