Patent Application
20100269809
The present invention relates to locking archery bows, and more particularly, to adjustable archery bow lock to pre vent dr y firing or otherwise unwanted firing of a bow as to not cause damage to the bow or injury to a person.
The bowstring 30 includes at least two sections 40a, 40b extending between the cams 42, 44. Bowstring section 40a is the section on which an arrow 50 is knocked. On some bows, bow string sections 40b are referred to as a cable. Mounted on the riser 20 above the shelf 35 of the bow 10 is an arrow rest 36, which supports an arrow 50 while the archer is preparing to shoot. Some compound bows 10 also have a cable guide 52 and a cable slide 54.
Archery Bows are available for inspection by archers and consumers at retail, archery shooting lanes designed for practice shooting and at outdoor trade shows. Unlike guns, archery bows are readily available for any person to pick up at home or off a rack and inspect the bow. Many bows are designed with significant “let off” representing a significant amount of poundage reduction to hold the bow in the firing position after it is fully drawn. Many bows have design letups between 20 and 40%. Naturally, people are not given arrows during their inspection of new and used archery bows. Consequently, many people attempt to draw the bow back towards “wall” position without an arrow ready for firing to feel the let off.
A fully drawn bow without an arrow in place to be fired is potentially very hazardous to the individual who has drawn the bow back and similarly could be very destructive to the bow itself if the testing person releases or “dry fires” the bow, even if accidentally. Firing or releasing an archery bow without an arrow causes enough shock and vibration that the bow may actually break apart or “blow up” with the limb portions 22a and 24a actually delaminating causing bow parts as enumerated above to blow up, break apart and to go flying in all different directions causing potential significant harm to bystanders and the person inspecting the bow.
There is a significant need for an adjustable archery bow lock that will secure the archery bow to be inspected into a steady resting state not permitting the bow to be drawn which could possibly result in a dry fire and damage the bow as well as hurt people.
An adjustable archery bow lock for an archery bow with bow strings, or a limb with a cam or a pulley, includes a locking first frame with first and second rod receiving apertures there through A lock mechanism is on the first frame with a moveable and securable locking index pin. A parallel second frame has first and second rods that are adapted to capture and immobilize the bow strings, or the cam or pulley with the limb. The rods pass through the receiving apertures. The second rod has a series of aligned indentations. The rods are secured to the first frame with the locking index pin secured into one of the indentations to prevent drawing or firing of the bow.
The principal object and advantage of the present invention is that the adjustable archery bow lock provides absolute safety to people who inspect compound archery bows at home, the point of sale or at a demonstration shooting lane. The archer simply cannot draw the bow string to a firing position as the bow strings, or cam with the limb, are completely immobilized by the lock.
Another object in advantage of the present invention is the prevention of “dry firing” or the release of an archery bowstring without a loaded arrow which results in significant shock to the bow which may cause the bow to literally explode with the limbs delaminating in parts dangerously flying about rendering the bow completely destroyed.
Another object in advantage of the present invention is that the archery bow lock is adjustable as to secure the lock to the bow about the bow strings, or the limb and pulley, of any of a variety of compound bows.
Another object in advantage of the present invention is that the archery bow lock, when securing the strings, is also supported by the cable guide.
Another object and advantage of the archery bow lock is that it provides an anchor or gripping ring suitable for a chain or cable to prevent theft of the archery bow from its point of sale or display.
Referring to
An anchor or gripping ring 112 may be used for interlocking many archery bows together with a chain and is also suitable for supporting the lock 100 by way of ring 112 encompassing the cable guide 52. First frame 102 has an extension 114 whereat is located first rod aperture 116 and space therefrom is second rod aperture 118. A second parallel frame 122 is generally u-shaped and to be oriented generally parallel to the first frame. Second, frame 122 also has a frame extension 124 whereat is located first rod aperture 126 which supports first rod 128 therein and is secured thereat with set screw 132. Spaced inwardly from the first rod aperture 126 is second rode aperture 134 which supports second parallel rod 136 secured thereat by set screw 138. The second parallel rod 136 has a series of aligned indentations 140 for interlocking with the indexing pin 110 of the locking first frame 102.
It can now be appreciated that the adjustable archery bow lock 100 is generally in two pieces comprised of first locking frame 102 and second parallel frame 122. First and second rods 128 and 136 are aligned with the apertures 116 and 118 of the locking first frame respectively. The first frame 102 and second frame 122 may then telescope toward away from each other to the desired distance for locking. Thereafter, the key 104 is rotated to actuate the key lock mechanism 106 to rotate latch 108 and secure indexing pin 110 into one of the indentations 144. Disassembly of the lock is handled in the reverse order with rotation of the key 108 disengaging the index pin 110 with the indentation and separating the first frame 102 from the second frame.

It can be appreciated that a magnet 166 rubbed across the face of the first locking frame 156 will move steel pin 160 rearwardly to permit the second parallel rod 152 to pass into the first frame 156 to a particular location whereat the magnet is released and spring 162 urges steel pin 160 through one of the aligned holes 154 of the second parallel rod 152 that are aligned with bore 158.
