Abstract

A bracket assembly for adjusting the elevation of a bowsight includes a first bracket portion and a second bracket portion spaced from the first bracket portion and adapted for connection to a bowsight. A first pivot arm extends between the first and second bracket portions and is connected thereto via first and second pivot joint assemblies, respectively. A second pivot arm extends between the first and second bracket portions and is connected thereto via third and fourth pivot joint assemblies, respectively. A range adjustment assembly is operably associated with one of the pivot arms and the first bracket portion to thereby cause pivoting movement of the first and second pivot arms and thus movement of the second bracket portion with respect to the first bracket portion to thereby adjust the elevation of a bowsight when connected to the second bracket portion.

Dependent claims

A bracket assembly for adjusting the elevation of a bowsight, the bracket assembly comprising:

a first bracket portion;
a second bracket portion spaced from the first bracket portion and adapted for connection to a bowsight;
a first pivot arm extending between the first and second bracket portions and connected thereto via first and second pivot joint assemblies, respectively;
a second pivot arm extending between the first and second bracket portions and connected thereto via third and fourth pivot joint assemblies, respectively;
each pivot joint assembly comprising:
a first pivot opening formed in each pivot arm;
a second pivot opening formed in each bracket portion in alignment with the first pivot opening;
a slanted engagement surface associated with one of the first and second pivot openings, the slanted engagement surface forming a seat;
a bushing having a head portion, a shank portion extending from the head portion and first inner threads formed in the bushing;
the shank portion extending through the first and second pivot openings so that the pivot arm and bracket portion mutually rotate about the shank portion;
a bearing washer having a frustoconical surface located on the shank portion of the bushing, with the frustoconical surface adjustably engaging the seat of the first pivot opening such that the slanted engagement surface of the first pivot opening engages the frustoconical surface of the bearing washer with adjustable frictional force to thereby vary a force required for mutual rotation of the pivot arm and bracket;
a first fastener having a fastener head and a threaded portion extending from the fastener head, with the fastener head pressing against one of the bracket and bearing washer, and the head portion of the bushing pressing against the other of the bracket and the bearing washer, with the threaded portion of the fastener engaging the first inner threads of the bushing;
wherein tightening the fastener causes the head portion of the bushing to draw towards the fastener head thereby pressing the frustoconical surface of the bearing washer against the slanted engagement surface of the seat while sandwiching the bracket and the pivot arm therebetween, while and varying the frictional force therebetween and thus the force required for mutual rotation of the pivot arm and bracket portion, even with loose tolerances in the pivot joint assembly.

a second pivot arm extending between the first and second bracket portions and connected thereto via third and fourth pivot joint assemblies, respectively;
a range adjustment assembly operably associated with one of the pivot arms and the first bracket portion to thereby cause pivoting movement of the first and second pivot arms and movement of the second bracket portion with respect to the first bracket portion to thereby adjust the elevation of a bowsight when connected to the second bracket portion;
at least the second and fourth pivot joints being spaced from each other a predetermined distance and being stationary with respect to the first bracket portion;
mechanical fastening elements associated with the second and fourth pivot joints for connecting a quiver mounting portion thereto;
and
a quiver mounting portion connectable to the second and fourth pivot joints such that the quiver mounting portion is stationary with respect to the first bracket portion independent of movement of the second bracket portion.

A bracket assembly for adjusting the elevation of a bowsight, the bracket assembly comprising:

a first bracket portion;
a second bracket portion spaced from the first bracket portion and adapted for connection to a bowsight;
a first pivot arm extending between the first and second bracket portions and connected thereto via first and second pivot joint assemblies, respectively;
a second pivot arm extending between the first and second bracket portions and connected thereto via third and fourth pivot joint assemblies, respectively;
and
a range adjustment assembly operably associated with one of the pivot arms and the first bracket portion to thereby cause pivoting movement of the first and second pivot arms and movement of the second bracket portion with respect to the first bracket portion to thereby adjust the elevation of a bowsight when connected to the second bracket portion;
wherein the range adjustment assembly comprises:
a first elongate gear connected to the first bracket portion;
a second gear that meshes with the first elongate gear;
an adjustment wheel operably associated with the second gear to thereby rotate the second gear with respect to the first elongate gear;
and
a brake assembly operably associated with the adjustment wheel to prevent movement thereof, the brake assembly including:
a lock knob rotatably connected to the adjustment wheel for manipulation by a user, the lock knob being rotatably connected to the adjustment wheel at a location spaced from an axial center of the adjustment wheel;
a drum connected to the adjustment wheel for rotation therewith, the drum having a braking surface;
and
a brake operatively associated with the lock knob such that rotation of the lock knob causes the brake to press against the braking surface of the drum, thereby locking the drum and the adjustment wheel against movement, and thus the first and second bracket portions, against relative movement.
