Cushioned carabiner clip

Abstract

The present invention relates to an improved carabiner system, including an impact-dampening cushion around the external surface of the frame for cushioning damage during a fall or collision and to reduce sound from loose or swinging carabiner collisions. Additional surface routing and through holes provide improved register between the carabiner frame and the over-molded cushion layer.

What is claimed is: 
     
         1 . A carabiner, comprising:
 a frame having a proximal end and a distal end at opposite ends of an elongated section with a gate opening between the proximal end and the distal end, the frame having an internal surface generally defining an interior cavity and an external surface opposite the internal surface;   a gate pivotally attached to the proximal end of the frame to span the gate opening and configured to open and close for access to the interior cavity of the frame, the gate and the frame together forming a closed shape when the gate is closed;   a lock configured to secure the gate relative to the frame; and   a cushion layer secured to and covering a portion of the external surface of the frame.   
     
     
         2 . The carabiner of  claim 1 , wherein the lock includes a rotating fastener. 
     
     
         3 . The carabiner of  claim 1 , wherein the frame includes:
 a first through-hole between the proximal end and the first concave curved portion;   a second through-hole between the distal end and the second concave curved portion; and   a third through-hole between the first concave curved portion and the spine;   wherein each of the through-holes extend from a first side surface of the frame between the internal surface and the external surface to a second side surface of the frame between the external surface and the internal surface, the second side surface being opposite the first side surface.   
     
     
         4 . The carabiner of  claim 3 , wherein:
 a first groove is formed on the first side surface of the frame; and   a second groove is formed on the second side surface of the frame;   wherein the material of the cushion layer fills the first and second grooves and loops through each of the first, second, and third through-holes, strengthening the bond between the cushion layer and the frame.   
     
     
         5 . The carabiner of  claim 1 , wherein the entire internal surface of the frame is exposed. 
     
     
         6 . The carabiner of  claim 5 , wherein the frame further comprises:
 a spine positioned opposite the interior cavity from the gate opening;   a first concave curved portion connecting the spine to the proximal end; and   a second concave curved portion connecting the spine to the distal end.   
     
     
         7 . The carabiner of  claim 6 , wherein the cushion layer covers the external surface of the spine. 
     
     
         8 . The carabiner of  claim 6 , wherein the cushion layer continuously covers the external surface of the frame from the first concave curved portion to the second concave curved portion. 
     
     
         9 . The carabiner of  claim 8 , wherein the frame includes at least one groove and the material of the cushion layer fills and attaches to the at least one groove to increase the bond between the cushion layer and the frame. 
     
     
         10 . The carabiner of  claim 9 , further comprising one or more through-holes extending through the frame, and the material of the cushion layer loops through the at least one through-hole. 
     
     
         11 . The carabiner of  claim 8 , wherein:
 a first groove is formed on a first side surface of the frame between the internal surface and the external surface and the material of the cushion layer fills and attaches to the first groove, strengthening the bond between the cushion layer and the frame; and   a second groove is formed on a second side surface of the frame between the external surface and the internal surface, the second side surface being opposite the first side surface, and the material of the cushion layer fills and attaches to the second groove, strengthening the bond between the cushion layer and the frame.   
     
     
         12 . The carabiner of  claim 1 , wherein the lock is a screw-type lock. 
     
     
         13 . The carabiner of  claim 1 , wherein the lock is a screw-type lock having a screw-type rotating fastener. 
     
     
         14 . The carabiner of  claim 1 , wherein the lock can form a rigid sleeve to cover a portion of the gate and a portion of the frame. 
     
     
         15 . A carabiner, comprising:
 a frame having a proximal end and a distal end at opposite ends of an elongated section with a gate opening between the proximal end and the distal end, the frame having an internal surface and an external surface opposite the internal surface;   a gate pivotally attached to the proximal end of the frame to span the gate opening and configured to open and close for access to the interior cavity of the frame, the gate and the frame together forming a closed shape when the gate is closed;   a lock configured to secure the gate relative to the frame, wherein the lock includes a rotating fastener; and   a cushion layer secured to and covering a portion of the external surface of the frame.   
     
     
         16 . The carabiner of  claim 15 , wherein the rotating fastener is a screw-type rotating fastener. 
     
     
         17 . The carabiner of  claim 15 , wherein the frame and the gate are formed of the same material. 
     
     
         18 . The carabiner of  claim 15 , wherein the frame and the gate are electro-polished or electro-coated. 
     
     
         19 . The carabiner of  claim 15 , wherein the frame and the gate are shaped by bending alloy rods into the desired shape. 
     
     
         20 . A carabiner, comprising:
 a frame having a proximal end and a distal end at opposite ends of an elongated section with a gate opening between the proximal end and the distal end, the frame having an internal surface and an external surface opposite the internal surface;   a gate pivotally attached to the proximal end of the frame to span the gate opening and configured to open and close for access to the interior cavity of the frame, the gate and the frame together forming a closed shape when the gate is closed;   a lock configured to secure the gate relative to the frame; and   a cushion layer secured to and covering a portion of the external surface of the frame, wherein the entire internal surface of the frame is not covered by the cushion layer.
