Slider with two pull tabs

Abstract

A description is given of a slider ( 1 ) with two pull tabs ( 2, 3 ) arranged symmetrically with respect to each other and each provided with a ring ( 2 a, 3 a ), the slider comprising a hollow body ( 4 ) containing an escapement ( 5 ), the pawl ( 6 ) of which is designed to be inserted between the teeth of the zip in order to prevent movements between the zip and the slider ( 1 ), the escapement ( 5 ) being provided with elastic means ( 7 ) which keep its pawl ( 6 ) inserted between the teeth until it is disengaged by one or other of the pull tabs ( 2, 3 ). In the slider in question one ( 2 ) of the pull tabs ( 2, 3 ) is in contact with the escapement ( 5 ) via its ring ( 2 a ) in such a way that, when operated, it produces the said disengagement, and the other pull tab ( 3 ) is positioned with its ring ( 3 a ) in contact with an inclined plane ( 8 ) of a rigid member ( 9 ) which is positioned in such a way that operating the abovementioned pull tab ( 3 ) causes a rotation of the rigid member ( 9 ) sufficient to press it against one end ( 20 i ) of a movable pin ( 10 ) and to move it axially in such a way that the other end ( 20 s ) pushes the escapement ( 5 ), overcoming the resistance of the said elastic means ( 7 ) and disengaging the pawl ( 6 ) thereof.

1 . Slider ( 1 ) with two pull tabs ( 2 ,  3 ) arranged symmetrically with respect to each other and each provided with a ring ( 2   a ,  3   a ), the slider comprising a hollow body ( 4 ) containing an escapement ( 5 ), the pawl ( 6 ) of which is designed to be inserted between the teeth of the zip in a reversible manner in order to prevent undesired movements between the zip and the said slider ( 1 ), this escapement ( 5 ) being provided with elastic means ( 7 ) which keep its pawl ( 6 ) inserted between the teeth until it is disengaged by one or other of the said two pull tabs ( 2 ,  3 ), enabling the slider ( 1 ) to be moved with respect to the abovementioned teeth, which slider ( 1 ) is characterized in that one ( 2 ) of the pull tabs ( 2 ,  3 ) is directly in contact with the said escapement ( 5 ) via its ring ( 2   a ) in such a way that, when operated, it produces the said disengagement, and the other pull tab ( 3 ) is positioned with its ring ( 3   a ) in contact with an inclined plane ( 8 ) forming part of a shaped rigid member ( 9 ) contained in the hollow body ( 4 ), this inclined plane ( 8 ) being positioned in such a way that operating the abovementioned pull tab ( 3 ) causes a rotation of the rigid member ( 9 ) sufficient to press it against one end ( 20   i ) of a movable pin ( 10 ) housed in the body ( 4 ) of the slider ( 1 ), and to move it axially in such a way that its other end ( 20   s ) pushes the said escapement ( 5 ), overcoming the resistance of the said elastic means ( 7 ) and disengaging the pawl ( 6 ) thereof from the teeth of the zip.  
   
   
       2 . Slider with two pull tabs according to  claim 1 , in which the said elastic means are a strip ( 7 ) which flexes elastically, is integral with the said escapement and is housed in the hollow body ( 4 ) of the slider ( 1 ) in such a way as to press against an internal wall ( 4   p ) thereof.
