Detachable drawlock and method of attachment to a bow

Abstract

A method of mounting a detachable drawlock to a compound bow is disclosed. It consists of a fixture attached to the bow and a drawlock having complimentary mounting means that fit in the fixture securely but detatchably. A detatchable drawlock is disclosed wherein the bow mounted fixture is a quiver mounting block that attaches at the bow sight. The detatchable drawlock comprises a mounting plate bearing the same mounting means as the quiver which detatchably mounts in the quiver mounting block, a rod attached to the mounting plate to hold the draw, and a mechanical release at the distal end. The mechanical release disclosed comprises a string catch that is spring biased to the cocked position, a trigger, and a safety that is spring biased to the on position. The drawlock carries on the quiver for transportation and storage.

1 . A means of securely mounting a detatchable drawlock on an archery bow having limbs, bowstring, and a riser, said means comprising a fixture mounted on the bow, said fixture having one or more holding means to securely hold a drawlock which has holding means to engage the fixture holding means in a complimentary and removable manner. 
   
   
       2 . The drawlock and archery bow of  claim 1  having limbs, riser, arrow rest mounting threaded hole, and two threaded holes in its riser for mounting a bow sight, with a bow sight thereon, said means consisting of a mounting fixture attached to the bow along with said bow sight by means of said two holes in the riser, and a drawlock bearing means to securely attach to said mounting fixture in a complimentary and removable manner. 
   
   
       3 . The drawlock and bow and sight of  claim 2  wherein the sight is attached to the bow by means of the two threaded holes in the riser, and the sight has two auxiliary holes of the same spacing as the riser holes for mounting a quiver block, said mounting fixture being attached at the auxiliary holes, and a drawlock having means to securely attach to said mounting fixture in a complimentary and removable manner. 
   
   
       4 . The drawlock, bow and bow sight of  claim 2  wherein the mounting fixture is a quiver mounting block having means to securely but detachably mount a quiver bearing complimentary attaching means, and a drawlock which also has attaching means able to securely and detachably mount to said quiver mounting block. 
   
   
       5 . The drawlock, bow and bow sight of  claim 3  wherein the mounting fixture is a quiver mounting block having means to securely but detachably mount a quiver bearing complimentary attaching means, and a drawlock which also has attaching means able to securely and detachably mount to said quiver mounting block. 
   
   
       6 . The drawlock of  claim 1 , wherein the drawlock consists of a mounting plate with means to mount securely but detachably to said bow mounted fixture, a rod attached to said mounting plate, and a mechanical bowstring release mechanism capable of holding a bow at full draw and releasing the bowstring upon actuation of a trigger mechanism. 
   
   
       7 . The quiver, and drawlock of  claim 4  wherein the quiver has a first end bearing a basket for the heads of arrows and an attaching means to hold said drawlock mounting plate, a shank bearing its own complimentary mounting means, and a second end having an arrow retainer for retaining the shafts of arrows, and a means to hold the rod of a drawlock in a manner and position such that the arrow shafts and drawlock rod do not interfere with one another or with the mounting of the drawlock bearing quiver onto the bow. 
   
   
       8 . The mechanical bowstring release mechanism of  claim 5  wherein the mechanical bowstring release mechanism comprises:
 a body providing support for pivot pins, a cavity to protect internal parts, and a tubular projection with hole sized to fit the drawlock rod;   a pivotally mounted string catch rotatable between cocked and released positions, having a finger-like projection for holding the bowstring at full draw, which in the cocked position extends from the body roughly perpendicular to the rod and which in the released position points generally in the direction of the bow thereby releasing the bowstring, and a control surface for controlling the rotation from the cocked position to the released position;   a trigger pivotally mounted inside the body having an internal end and an external end, the internal end being rounded with an arc whose center is the pivot point, and the external end spring biased in the direction of the bow, said trigger being rotatable between a first position in which the internal end contacts the control surface of the string catch in its latched position keeping it from rotating to the released position, and a second position in which the internal end is rotated out of contact with the string catch allowing the string catch under load of the bowstring to rotate to the released position;   a safety having a solid mass movable between an on position in contact with a trigger surface in a manner that prevents trigger rotation, and an off position wherein the mass no longer prevents rotation of the trigger; and a controlling means that allows an archer to move the mass between the on and off positions.   and a cover for the body.   
   
   
       9 . The mechanical bowstring release mechanism of  claim 7  in which the string catch is spring biased to the cocked position so that the mechanism is self cocking. 
   
   
       10 . The mechanical bowstring release mechanism of  claim 7  wherein the safety consists of:
 a trigger with a hole, slot, or groove located between the internal end and the pivot point;   a button extending out of the body capable of moving only between a first position and a second position;   a spring that biases the button to the first position;   a rod sized to fit loosely into said hole, slot, or groove in the trigger and attached to the button, said rod lying in contact with a trigger surface adjacent to the hole, slot or groove when the button is in its first position, thus keeping the trigger from rotating, whereas when the button is in its second position the rod lies in line with the hole, slot, or groove allowing the trigger to rotate as the rod passes into the hole, slot, or groove;   complimentary bearing surfaces for the button in the cover and body which limit button travel to movement only between the first and second positions and prevent button rotation.   
   
   
       11 . A means of attaching a drawlock to an archery bow having limbs, bowstring, riser, an arrow rest, and two threaded holes in the riser for the installation of a bow sight, said means consisting of a plate attached to the bow using the threaded bow sight holes, said plate extending generally in the direction of the arrow rest, and having appropriate shape and means to attach a drawlock. 
   
   
       12 . A means of attaching a drawlock to the archery bow of  claim 10  having limbs, having a bow sight mounted thereon with two auxiliary holes for mounting a quiver mounting block, said means consisting of a plate attached to the bow using the auxiliary holes in the bow sight, said plate extending generally in the direction of the arrow rest, said plate also having appropriate shape and bearing means to attach a drawlock.
