Key-holder

Abstract

An improved key holder consisting of a case ( 1 ) provided with a central body ( 2 ), having in its upper part a semicircular area ( 3 ) and a lower curved one ( 4 ), the body ( 2 ) having on one of its faces, a longitudinal groove ( 6 ) dividing in two similar areas, having a projection ( 7 ) located in the blind face, incorporating a central recess and a longitudinal projection ( 8 ) in the groove ( 6 ), being covered with a body ( 10 ).

1 .- An improved key holder, made as from an external case and an internal part which is moved inside in a transverse direction and in both directions, characterised on consisting of a case ( 1 ) having a central body ( 2 ) configured by two flat and parallel areas terminating in the upper part through a semicircular area ( 3 ) and in the lower part through an area ( 4 ) with a semicircular curved configuration, the body ( 2 ) having on one of the faces a longitudinal groove ( 6 ) covering the area where it is situated, dividing it in two similar areas, likewise being situated along the surface of the semicircular area ( 3 ) and finishing in the rear face, having in inside the case ( 1 ) and matching with the upper internal area a longitudinal projection, as well as a projection ( 7 ) located in the blind face not having the groove ( 6 ), provided with a central sunken line and likewise, having on this blind face not having the groove ( 6 ), a longitudinal projection ( 8 ) having a protuberance ( 5 ) with a central perforation in the external area of the curved area ( 4 ).  
     
     
         2 .- An improved key holder according to the first claim, characterised in that inside the case ( 1 ) there is a holding body ( 10 ) manufactured in plastic material as the part ( 1 ) formed by two straight and parallel side walls ( 11 ) and ( 11 ′) joined in the lower part by a curved semicircular area matching the internal zone of the area ( 4 ) of the part ( 1 ), the two areas ( 11 ) and ( 11 ′) being joined in the upper part by two semicircular projections ( 12 ) and ( 12 ′) on whose internal faces there is a transversely located body ( 14 ) having a notch or perimetric bottleneck ( 15 ), likewise having on one of its faces, the part ( 10 ) of a traverse ( 18 ) with a rectangular plant situated in parallel with a blind area ( 16 ) provided with vertical and parallel grooves ( 17 ).  
     
     
         3 .- An improved key holder according to the previous claims, characterised in that in the grooves ( 17 ) the spring ( 8 ) of the part ( 1 ) is coupled, likewise the spring ( 7 ) being coupled between the traverse ( 18 ) and the wall ( 16 ), being likewise coupled the parts ( 1 ) and ( 10 ) by means of the projection ( 9 ) emerging from the internal area of the part ( 1 ) in the area corresponding to the semicircular zone ( 3 ) and the trapezoidal recess ( 13 ) existing in the area ( 12 ) and ( 12 ′) of the part ( 10 ).  
     
     
         4 .- An improved key holder according to the previous claims, characterised in that over the axis ( 14 ) of the part ( 10 ) parts ( 20 ) are coupled adopting the semicircular shape ( 21 ), provided with a central opening ( 22 ) terminating in its internal area in a semicircular configuration, the part ( 20 ) being coupled over the transverse body ( 14 ) by means of its bottleneck or perimetric notch ( 15 ), the part ( 20 ) having in the access area to the area ( 22 ) two thickenings ( 24 ) and in the general context of the semicircular zone, a significant reduction of its volume in thickness ( 23 ) where the head of the machined key ( 40 ) is coupled.  
     
     
         5 .- An improved key holder according to the previous claims, characterised on having a part ( 30 ) manufactured in plastic material equal to that of the part ( 20 ) adopting the semiangular configuration having a body ( 31 ) which at one of its ends has a transverse thickening ( 32 ), this part ( 30 ) being coupled over the groove ( 6 ) in the case area ( 3 ).
