Key ring accessory

Abstract

The present invention relates to a key ring accessory for a key ring which is a ring of substantially two turns resiliently urged towards each other formed by looping, comprising a body which can removably be engaged with the key ring and at least one protruding member is disposed on one of the inner walls of the body, the end projecting from the protruding member being a pointed end. When the present invention is engaged with the key ring, the key ring can easily be pried open for inserting and/or removing a key. The present invention is of simple construction and is adapted for use with a conventional loop-shaped key ring. It will not break the fingernail or hurt the fingers of a user. It does not require any external aids to pry open the resiliently urged turns of the key ring, thereby making it effort-saving and convenient to insert and/or remove a key. Further, a user does not need to take out other keys when a particular key is to be removed, thereby reducing the chance of losing keys and making the process of removing a key fast and convenient.

1 . A key ring accessory for a key ring which is a ring of substantially two turns resiliently urged towards each other formed by looping, comprising a body which can removably be engaged with the key ring and at least one protruding member is disposed on one of the inner walls of the body, the end projecting from the protruding member being a pointed end. 
   
   
       2 . A key ring accessory as in  claim 1 , wherein the body is a hollow ring-shaped body which can move along the key ring after having engaged with the key ring. 
   
   
       3 . A key ring accessory as in  claim 1  or  claim 2 , wherein the external appearance of the body is in a rectangular, a square, an elliptical or a semi-elliptical form. 
   
   
       4 . A key ring accessory as in  claim 1 , wherein the protruding member is disposed on the inner wall of the body near the central position, the widths of the inner wall of the body on the two sides of the protruding member each is at least greater than half of the thickness of the key ring for retaining the two resiliently urged turns when the key ring is pried open by the protruding member; other inner walls of the protruding member and the body are respectively kept clear with space for the key ring to move freely in relation to the body. 
   
   
       5 . A key ring accessory as in  claim 1  or  claim 4 , wherein two protruding members are disposed on one of the inner walls of the body, the two protruding members are spaced apart in a row with one protruding member disposed near the periphery of the opening on one side of the body and the other protruding member disposed near the periphery of the opening on the other side of the body. 
   
   
       6 . A key ring accessory as in  claim 1 , wherein the depth of the inner wall of the body on which the protruding member is disposed or the outer wall thereof is a value in between two to five times of the distance between the outer circumference and the inner circumference of the key ring for preventing it from being too small to cause inconvenience for finger tips to operate and from being too large to impede the movement of the body. 
   
   
       7 . A key ring accessory as in  claim 1 , wherein the length of each of the other inner walls of the body on which the protruding member is not disposed is a value in between three to seven times of the distance between the outer circumference and the inner circumference of the key ring for preventing it from being too short to cause inconvenience for the key ring to move in relation to the body and from being too long to require additional effort to pry open the two resiliently urged turns of the key ring with the protruding member. 
   
   
       8 . A key ring accessory as in  claim 1 , wherein the thickness of the protruding member is at least greater than half of the thickness of the key ring for allowing a sufficiently large gap to be pried open. 
   
   
       9 . A key ring accessory as in  claim 1 , wherein the pointed end projecting from the protruding member is in triangular shape with a sharp angle pointing out or in the shape of an arrow head with the arrow head pointing out. 
   
   
       10 . A key ring accessory as in  claim 1  or  claim 9 , wherein the pointed end of the protruding member is in an arrow head shape, the section connecting to the pointed end is slightly narrower than the end of the arrow head, the length of the section connecting to the end of the arrow head is adapted to be just greater than the distance between the outer circumference and the inner circumference of the key ring, for allowing the two resiliently urged turns of the key ring being pried open to be temporarily retained on the right and left sides of the protruding member respectively preventing them from slipping out easily. 
   
   
       11 . A key ring accessory as in  claim 1  or  claim 9 , wherein the pointed end of the protruding member is in triangular shape, the width of the section connecting to the pointed end and the length of the triangular base are substantially the same, the length of the section connecting to the triangular base is adapted to be just greater than the distance between the outer circumference and the inner circumference of the key ring, for allowing the two resiliently urged turns of the key ring being pried open to be temporarily retained on the right and left sides of the protruding member respectively. 
   
   
       12 . A key ring accessory as in  claim 1 , wherein one or more apertures are opened on the wall of the body on which the protruding member is disposed for removably attached to a hanging ornament. 
   
   
       13 . A key ring accessory as in  claim 1 , wherein one or more apertures are opened on the other walls of the body for removably attached to a hanging ornament. 
   
   
       14 . A key ring accessory as in  claim 1  or  claim 5 , wherein one or more apertures are opened on the wall of the body on which the two protruding members are disposed in between the two protruding members for removably attached to a hanging ornament, the connecting part of the hanging ornament can be stowed in between the two protruding members to prevent it from impeding the movement of the protruding members.
