Abstract
The archery arrow rest device includes an arrow launcher in the form of an upwardly and forwardly extending blade having a forked upper end for contacting the underside of an arrow shaft, flanked by a pair of flexible, resilient, bendable, upwardly and forwardly extending wire arms for gripping the opposite sides of the arrow shaft. Those arms are connected to the launcher or to a transverse support arm, as is the launcher. The launcher may be pivotally connected to such transverse arm, and biased to a position perpendicular to the transverse arm by springs connected to it or to the arrow-gripping arms so as to eliminate the need for a plunger. The transverse arm is laterally adjustably received in a block securable to the side of an archery bow riser to adjustably support the launcher at a desired location in the bow window. The launcher may be of resiliently depressible material and/or may be rotatable into a depressed position but spring biased to the upright position along with the transverse arm. Such transverse arm may be square in cross-section, toothed as its four exterior edges and driven by a wheel in the block. A click stop mechanism may be attached thereto.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to sports devices and more particularly to an improved type of archery bow arrow rest.
2. Prior Art
Conventional archery bow arrow rests support the arrow shaft in the archery bow window before launching of the arrow. Most such supports are merely shelves attached to the sidewall of the bow and projecting horizontally into the bow window through which the arrow passes during shooting. It has been found that most rests interfere to some degree with arrow flight, deflecting the arrow from its intended path because the arrow feathers or vanes strike the rest during shooting. This also causes wear of feathers and vanes, inducing erratic arrow flight and requiring frequent vane and feather replacement.
Collapsible rests have been devised to solve this problem, but are expensive and not entirely efficient and reliable. Moreover, most rests do not sufficiently support the arrow shaft to prevent its inadvertent movement thereon during drawing of the bowstring by the fingers, or with a tab and even with some types of mechanical releases, thus shifting the target hit point. They also do not prevent the arrow from rolling off the rest if the arrow is carried on the rest before the bowstring is drawn. This is sometimes done in hunting, where a hit may depend on the hunter's ability to shoot an arrow in a split second of opportunity.
A further difficulty with most rests is that they do not obviate the need for a separate side-pressure plate or cushion plunger projecting into the window from the bow sidewall so as to bear against the side of the arrow shaft and absorb some of the arrow shaft side bending forces (archer's paradox) encountered during arrow shooting with fingers. Such pressure plate or plunger, although expensive, is also useful when mechanical releases are employed because shaft side bending still occurs to some degree. However, the plunger must be adjusted to work well and it forms a separate mechanical obstruction against which the arrow vanes or feathers can readily strike to deflect the arrow from the desired target point during shooting.
Accordingly, there is a need for an improved type of arrow rest which will prevent arrow shifting and roll-off while the arrow is stored or carried thereon, thereby making it ready for instant use, as is desirable and sometimes required in many hunting circumstances. Such rest preferably should also eliminate the need for a side pressure plate or cushion plunger, yet provide improved unimpeded, smooth arrow flight and greater speed and shooting accuracy, without feather or vane wear. Such rest should also be resiliently depressible to absorb the downward pressures exerted on the arrow at bowstring release during shooting. Moreover, the rest should be readily adjustable in position in the bow window in order to accommodate to various bows and arrows.
SUMMARY OF THE INVENTION
The improved rest device of the present invention staisfies all the foregoing needs. The device is substantially as set forth in the Abstract. Thus it features a slim upwardly and forwardly extending fork-tipped, resilient launcher supported for vertical dispersion on a laterally adjustable cross-arm received in a block which is attachable to the bow sidewall so as to hold the launcher in the bow window.
The launcher is flanked by a pair of mantis-like resilient, flexible, bendable wire arrow-shaft-holding arms which extend upwardly and forwardly, but preferably slightly behind the launcher to form therewith a three-point arrow shaft cradle which prevents shaft shifting and roll-off from the rest. The resilient arms also act as a side pressure plate or cushion plunger. This is particularly the case when these arms and the launcher are pivotably secured to the cross-arm and spring biased to the upright position by an internal or external cross-arm spring. Fine tuning the bow, as is required with cushion plungers and the like, is obviated with this rest.
The cross-arm may be externally toothed, square in cross-section and incrementally advanceable with click stops, through the block for lateral micro-adjustment. Further features of the invention are set forth in the following detailed description and accompanying drawings.

DETAILED DESCRIPTION
FIGS. 1 and 2
Now referring to FIGS. 1 and 2, an arrow rest device 20 is shown therein which comprises a forwardly and upwardly extending thin blade 22 of preferably flexible metal, plastic or the like, with the upper end 24 thereof forked to provide a pair of spaced tines 26 and with the rear end (lower) thereof 28 releasably rigidly secured, as by a screw 30, within a slot (not shown) in a transverse support arm 32.
Arm 32 passes through the rear end of a forwardly extending block 34, shown in FIG. 1 secured to sidewall 36 which defines with shelf 38 a window 40 in the riser secion 42 of an archery bow 44. In this position, block 34 holds blade 22 spaced from sidewall 36 in window 40 and parallel to block 34.
Arm 32 is releasably and adjustably secured to block 34 by nuts 46 and 48, the latter bearing a screw 50 to which a spring 52 is connected, which spring is also connected to a screw 54 at the front underside of block 34. With this arrangement, arm 32 is adjustable transversely relative to block 34 and is rotatable around its longitudinal axis to rotate blade 22 with it between the about upright position shown in FIGS. 1 and 2 and a depressed position caused during shooting of an arrow from rest 20. Spring 52 biases blade 22 into the proper about upright position, which is reached when screw 50 strikes limit pin 56 on the side of block 34.
Device 20 also includes a pair of curved, mantis-like, flexible, resilient, bendable wire arms 58 secured to opposite sides of blade 22 and extending laterally, upwardly therefrom to terminate in flattened ends 60 adapted to contact the sides of an arrow shaft 62 while the underside of shaft 62 rests on tines 26. Arms 58 can be bent to accommodate any size of shaft 62 at the sides thereof either below, or at or above the midline thereof so as to support shaft 62 against any movement including roll-off while it is carried on device 20, as in hunting, with rear end of shaft 62 clipped to the bowstring (not shown). If arms 58 grip shaft 62 above its side mid-line, bow 44 can even be inverted without shaft 62 rolling off rest 20.
Since arms 58 are small, as is blade 22, and depress along with it during shooting, the arrow can be shot without its feathers or vanes striking any part of device 20, shooting accuracy thereby being improved. The side "give" of arms 58 allows a cushion plunger or the like to be obviated and still provide necessary cushioned side resistance to the side bending of shaft 62 during shooting, so that perfect arrow flight results. Arms 58 can be fitted with sleeves or tubes 64 of low frictional resistance plastic or the like for best results. Thus, device 20 is simple, inexpensive, durable and efficient in providing the desired results.
FIGS. 3 and 4
A second preferred embodiment of the present rest is schematically shown in FIGS. 3 and 4. Thus, device 20a is shown. Components thereof similar to those of FIGS. 1 and 2 bear the same numerals but are succeeded by the letter "a". Device 20a is identical to device 20 except that arms 58a have no sleeves, blade 22a is very resilient since no spring comparable to spring 52 is present, arm 32a is square in transverse cross-section, and toothed along its four exterior longitudinal edges, bolt 66 fits either of two contiguous holes 68 and 70 in block 34a to secure it to sidewall 36 and an incremental advance and click stop micro-adjustment mechanism is provided.
Thus, block 34a has a wheel 72 rotatbly secured therein around opening 74 in block 34a. Wheel 72 is grooved or threaded (not shown) so as to engage the external toothed edges of arm 32a and thus advance or retard arm 32a, depending on the direction of rotation of wheel 72. One face 72 of wheel 72 is provided with circumferentially spaced dimples 78 in which the blunted point 79 of a pin 80 extending into block 34a biased by a leaf spring 82 connected to block 34a by screw 83 is releasably engaged. As wheel 72 turns, point 79 successively moves out of and drops into one dimple 78 after another, providing a definite feel and an audible click each time it engages a dimple 78. Thus, micro adjustment of the position of arm 32a is provided. Stop nut 84 or the like may also be provided on free end 86 of arm 32a. Device 20a operates similarly to device 20 and has the advantages thereof.
FIGS. 5 and 6
FIG. 5 shows a version of the transverse arm utilized in the rest device of the present invention. The arm is designated 32b and has a top slot 88, lock screw 30b and threaded end 86b with lock nut 84b. FIG. 6 shows a version of the transverse arm designated 32c and having a slot 88c, lock screw 30c and plain unthreaded shaft. Arms 32b and 32c can be substituted for arm 32.
FIG. 7
A third preferred embodiment of the present rest device is depicted in FIG. 7. Thus, rest 20d is shown, which is substantially identical to rests 20 and 20a in structure and function except that arm 32d is hollow and bears an internal coiled spring 90 releasably locked, as by pins 92 and 94, in holders 96 and 98, respectively, in arm 32d. Holder 96 is fixed in position, in non-rotating portion 100 of arm 32d, while holder 98 is connected to rotating portion 102 of arm 32d and rotates therewith against the action of spring 90.
Portion 102 bears blade 22d and arms 58d, as well as limit screw 104 adapted to strike limit pin 106 on portion 100 to control the proper resting position of blade 22d and arms 58d. The four exterior edges of portion 100 are toothed, as with arm 32a and arm 32d may be adapted to be incrementally transversely advanced, in the manner of arm 32a. Spring 90 controls the depressibility of blade 22d and arms 58d.
FIGS. 8 and 9
A fourth preferred embodiment of the improved rest device is depicted in FIGS. 8 and 9. Thus, rest 20e is shown which is identical to rest 20 in function and structure, except that arms 58e are releasably secured, as by pins 110, in sockets 112 in arm 32e. Blade 22e is flexible and resilient in the manner of blade 22a, and arm 32e is releasably locked in block 34e by screw 114, with lead ball 116 placed between arm 32e and screw 114 in order to protect arm 32e against marring.
FIG. 10
A fifth preferred embodiment of the improved rest device is depicted in FIG. 10. Thus, rest 20f is shown which is identical in function and structure to rest 20 (locking nuts similar to 46 and 48 and a block similar to block 34 not being shown), except that blade 22f is pivotably secured to arm 32, rather than fixed in position, by screw 30f, blade 22f bearing arms 58f with it, and except that a return spring 120 is coiled around the base of blade 22f with spaced arms 122 of spring 120 gripping opposite sides of blade 22f and allowing resilient side movement thereof while base 124 of spring 120 remains locked, as by screws 126, against movement in arm 32f. Thus, spring 120 returns blade 22f and arms 58f to a position perpendicular to arm 32f after their side deflection by an arrow shaft during shooting. Perfect arrow flight is provided by this rest device.
FIG. 11
A sixth preferred embodiment of the improved rest device is depicted in FIG. 11 (except for the mounting block thereof). Thus, device 20g is shown which is similar to device 20f in function and components, differing only in that a pair of spaced parallel coiled springs 130 connected to arms 58g on opposite sides of blade 22g and to the adjacent surfaces of arm 32g substitute for spring 120. Blade 22g freely pivots around screw 30g, carrying arms 58g with it and is returned to the perpendicular aspect shown in FIG. 11 by springs 130. Perfect arrow flight is also provided by this rest device. It is understood that rest devices 20f and 20g can be used in conjunction with the rest device of the FIG. 3 embodiment.
Various other modifications, changes, alterations and additions can be made in the improved rest device of the present invention, its components and their parameters. All such changes, modifications, alterations and additions as are within the scope of the appended claims form part of the present invention.
