Key ring

Abstract

Improved Key Ring: consists of a casing that contains a number of keys that are made available by the action of pressing one of a number of buttons, each button is associated with a particular key; the mechanism, that allows the release or extraction of each key, by means of the pressing an assigned button, comprises of an automatic system of folding the key, or piston arm, and a mechanical system of fixing and releasing the key or track.

1 . IMPROVED KEY RING, of the type designed to group together a number of routine/normal use keys within a casing, in which they remain hidden and ordered compactly, being extractible by means of a mechanical device, characterized by including a framework ( 1 ) one that holds inside a number of keys ( 2 ) extractible by means of the operation of a number of buttons ( 3 ), being that each button is ( 3 ) associated to a specific key ( 2 ); in which the mechanism that drives the extraction of each key ( 2 ) by means of the operation of the button ( 3 ) associated to said key ( 2 ) includes an automatic system for folding the key, or arm-piston ( 4 ) and a mechanical system of holding and releasing the key ( 2 ) or rail ( 5 ).  
   
   
       2 . IMPROVED KEY RING, according to  claim 1 , characterized as the working of the arm-piston ( 4 )it is comprised of a long piece ( 6 ) with a curved end that has holes and a cover ( 7 ) and a piston ( 8 ) that crosses the ( 9 ) common axis, secures the upper part of each key ( 2 ) and fixes it to the axis ( 9 ). In the interior of the casing ( 1 )there are as many arm-pistons ( 4 ) as keys ( 2 ) that have been connected to the key ring, and in turn connected to the axis ( 9 ); to allow the arm-piston ( 4 ) to carry out the automatic movement, arranged in its interior there is an elastic or soft element ( 10 ), secured to the piston ( 8 ) and to the piece ( 6 ) at the same time, allowing the mechanism an automatic movement if the arm-piston is rotated ( 4 ) on the axis ( 9 ) as a result of pressure from the spring ( 10 ).  
   
   
       3 . IMPROVED KEY RING, according to claims  1  and  2 , regarding the working of the mechanical system of holding and release of the key or rail ( 5 ), a button is comprised of ( 3 ), a hammer ( 11 ), a rocker ( 12 ), a rod ( 13 ), a pressure spring( 14 ) and a displacement spring ( 15 ); in which the rail ( 5 ) fixes the arm-piston ( 4 ) in its folded position, and releases the key to the use position ( 2 ), causing the arm-piston ( 4 ) to jump to the folded position, so that the rod ( 13 ) holds the arm-piston ( 4 ) in the fold position, as a result the rocker ( 12 ), through a system of springs, ( 14 ) and ( 15 ), pushes the rod ( 13 ) so that it holds the arm-piston ( 4 ); pressing the use button ( 3 ) chosen, pushes a hammer ( 11 ) and that in turn pressures the rocker ( 12 ) toward the opposite side to the pressure placed on the rocker ( 13 ), this causes a backward movement of the same thanks to the push of a spring ( 15 ) causing the arm-piston ( 4 ) to jump from its folded position and shoots the key ( 2 ) out of the casing ( 1 ).  
   
   
       4 . IMPROVED KEY RING, according to  claims 1  to  3 , regarding each key, the key ( 2 ) is associated with a mechanism that includes an arm-piston ( 4 ) a rail ( 5 ), each constituting a track ( 16 ), able to have as many keys ( 2 ) as tracks( 16 ) joined to the framework ( 1 ), being all associated to the same, and only, axis ( 9 ).  
   
   
       5 . IMPROVED KEY RING, according to the  claims 1  to  4 , regarding the buttons of operation, use buttons, ( 3 ) each is associated with a key ( 2 ), they may, optionally, be of different colours or alphanumeric signs and/or graphics enabling better identification of each key ( 2 ).
