Abstract

A compact, portable archery exerciser allows an archer to accurately emulate the pulling of a bow to tone and strengthen the muscles used in archery. A first embodiment of the exerciser comprises two elongated handle members which are interconnected at the ends by a selectable number of resilient members to provide an exerciser with a selectable pull weight. A second embodiment of the exerciser includes a housing having an internal chamber and a handle portion for receiving an archer's bow holding hand. A spring loaded pulley is mounted within the chamber and receives a cable which, when unwound from the pulley, compresses the spring. The cable is routed outside the chamber where it is attached to a handle which is positioned to allow an operator of the exerciser to pull the handle away from the handle portion of the housing to accurately simulate the pulling of a bow. An adjustable pulley mounted within the chamber engages the cable to allow adjustment of the pull weight of the second embodiment of the exerciser.

Dependent claims

An archery exerciser comprising:

first handle means for receiving the forward, bow holding hand of an archer at a position extended at arm's length from said archer, said first handle means comprising a housing including a central aperture defining a formed handle portion, said aperture being sized and shaped to provide adequate clearance for an operator's wrist and forearm during utilization of the exerciser;
second handle means for receiving the string pulling hand of said archer;
connecting means for resiliently connecting said first handle means to said second handle means, said connecting means mounted within said housing and comprising:
a spring loaded pulley, cable means wrapped around said pulley in a direction to increase the loading when said cable means is unwound from said pulley, alignment means for routing said cable means from said pulley through the sidewall of said housing, and means for securing said cable means to said second handle means;
and
spring control means for adjustably controlling the state of compression of said spring loaded pulley to vary the pull resistance of said exerciser, said spring control means comprising adjustable means mounted within said housing and engaging said cable means whereby said archer can simulate the action of pulling a bow by pulling said second handle means away from said first handle means.
