Safety pin with arcuate pin bar

Abstract

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.

1 . A safety pin, comprising: 
 a torsion spring coil having a stationary bar and a pin bar extending from opposite ends, the pin bar being arcuate and having a pointed end; and    a shield attached to the stationary bar, the shield extending at an angle relative to the stationary bar and defining a groove, whereby the pin bar is adapted for insertion through a material to be secured, being compressed toward the stationary bar and secured in the groove defined by the shield.    
   
   
       2 . The safety pin according to  claim 1 , further comprising a textured fin attached to the stationary bar for better gripping.  
   
   
       3 . The safety pin according to  claim 2 , wherein said fin has a linear inner edge and a linear outer edge.  
   
   
       4 . The safety pin according to  claim 2 , wherein said fin has a linear inner edge and a convex outer edge.  
   
   
       5 . The safety pin according to  claim 4 , wherein the pin bar has a radius of curvature substantially the same as a radius of curvature of the outer edge of the fin.  
   
   
       6 . The safety pin according to  claim 2 , wherein said fin has a concave inner edge and a convex outer edge.  
   
   
       7 . The safety pin according to  claim 6 , wherein the pin bar has a radius of curvature substantially the same as a radius of curvature of the outer edge of the fin.  
   
   
       8 . The safety pin according to  claim 2 , further comprising means for attaching a decoration to said fin.  
   
   
       9 . The safety pin according to  claim 2 , further comprising means for attaching identification to said fin to form a nametag or badge.  
   
   
       10 . A safety pin, comprising: 
 a torsion spring coil having a stationary bar and a pin bar extending from opposite ends, the pin bar being arcuate and having a pointed end, the stationary bar having an end bent backward at an angle; and    a shield attached to the angled end of the stationary bar, the shield extending at an angle relative to the stationary bar and defining a groove;    whereby the pin bar is adapted for insertion through a material to be secured, being compressed toward the stationary bar and secured in the groove defined by the shield.    
   
   
       11 . The safety pin according to  claim 10 , further comprising a textured fin attached to the stationary bar for better gripping.  
   
   
       12 . The safety pin according to  claim 11 , wherein said fin has a linear inner edge and a linear outer edge.  
   
   
       13 . The safety pin according to  claim 11 , wherein said fin has a linear inner edge and a convex outer edge.  
   
   
       14 . The safety pin according to  claim 13 , wherein the pin bar has a radius of curvature substantially the same as a radius of curvature of the outer edge of the fin.  
   
   
       15 . The safety pin according to  claim 11 , wherein said fin has a concave inner edge and a convex outer edge.  
   
   
       16 . The safety pin according to  claim 11 , wherein the pin bar has a radius of curvature substantially the same as a radius of curvature of the outer edge of the fin.  
   
   
       17 . The safety pin according to  claim 11 , further comprising means for attaching a decoration to said fin.  
   
   
       18 . The safety pin according to  claim 11 , further comprising means for attaching identification to said fin to form a nametag or badge.  
   
   
       19 . A safety pin, comprising: 
 a torsion spring coil having a fin and a pin bar extending from opposite ends of the coil, the pin bar being arcuate and having a pointed end; and    a shield attached to the fin, the shield extending at an angle relative to the fin and defining a groove, whereby the pin bar is adapted for insertion through a material to be secured, being compressed toward the fin and secured in the groove defined by the shield.    
   
   
       20 . The safety pin according to  claim 19 , wherein the fin has a convex outer edge.
