Titlting limb system for bows and crossbows and equipment formed therewith

Abstract

A coupling system for limbs ( 3 ) of archery devices ( 1 ) such as bows and crossbows, includes a pair of limbs ( 3 ) joined at their ends by a bowstring ( 4 ) which is used for loading the energy to be released onto the arrow and to the center onto a support ( 2 ) of the device. In this system, the limbs ( 3 ) are hinged to the support ( 2 ) in such a manner as to be movable about an axis (A 1 ) of a pin ( 5 ) for fastening together the support ( 2 ) and the limbs ( 3 ); the axis (A 1 ) being perpendicular to the plane that passes through the limbs ( 3 ) and the bowstring ( 4 ).

1 . A coupling system for limbs ( 3 ) of archery devices ( 1 ) such as bows and crossbows comprising a pair of limbs ( 3 ) joined at their ends by a bowstring ( 4 ) which is used for loading the energy to be released onto the arrow and to the center onto a support ( 2 ) of the device, characterized in that said limbs ( 3 ) are hinged to the support ( 2 ) in such a manner as to be movable about an axis (A 1 ) of a pin ( 5 ) for fastening together said support ( 2 ) and said limbs ( 3 ); said axis (A 1 ) being perpendicular to the plane that passes through the limbs ( 3 ) and the bowstring ( 4 ). 
   
   
       2 . A system as claimed in  claim 1 , characterized in that it provides one or more pad means ( 6 ) interposed between the support ( 2 ) and the limb ( 3 ) for absorbing part of the energy during the return stroke of the limb. 
   
   
       3 . An archery device ( 1 ), such as a bow or a crossbow, comprising a pair of limbs ( 3 ) joined at their ends by a bowstring ( 4 ) which is used for loading the energy to be released onto the arrow and to the center onto a support ( 2 ) of the device, characterized in that the limbs ( 3 ) are hinged to their support ( 2 ) by corresponding pins ( 5 ) to pivot about the axis (A 1 ) a few degrees forward (F 1 ) upon release of the string ( 4 ) and then reposition itself, during the return stroke (F 2 ), to abutment against the support ( 2 ), which acts as an abutment member for the limbs ( 3 ), thereby preventing them from excessively bending back to the center of the device ( 1 ) when the bowstring ( 4 ) is drawn. 
   
   
       4 . A device ( 1 ) as claimed in  claim 3 , characterized in that it comprises one or more pad means ( 6 ) between the support ( 2 ) and the limb ( 3 ) for absorbing part of the energy during the return stroke of the limb.
