Abstract
A sighting device for a bow which is fixedly mounted on a bow and which is provided with a lever and link arrangements such that a sight unit thereof is tilted at a progressively increasing rate as the sighting device is adjusted for longer distances so as to compensate for gravity effect on arrows. Also, the sight unit is so mounted whereby it tilts relative to the bow in a manner wherein the sight unit generally lies in a plane which is normal to the sighting axis therethrough for all adjustments of the sighting device.
Claims12
An adjustable sight for an archery bow, said sight comprising a support having means for fixedly mounting on a bow, said support having front and rear ends, an arcuate gauge on said support at said rear end, a lever having an intermediate position pivotally mounted on said support, said lever having front and rear ends, said lever rear end carrying a pointer cooperating with said arcuate gauge, a carrier plate pivotally mounted on said lever at said lever front end, a sight unit fixedly carried by said carrier plate, and a link extending between said carrier plate and said support front end and pivotally connected thereto, the relationship of said lever, said link and the connections between said lever and said link with said support and said carrier plate being one whereby for a uniform movement of said pointer along said gauge towards an increased target distance position there is a progressive increase in movement of said sight unit to compensate for the increase in effect of gravity.
