Description

BACKGROUND

Most popular sports, especially those enjoyed by a more avid or puritanical group of enthusiasts, offer a variety of accessories which make participation in the activity more enjoyable and/or more proficient. Bow hunting may be viewed as one such activity which requires a much higher/greater degree of skill and proficiency, than, perhaps, a hunter who employs a common firearm or rifle. To prevent an archer employing a bow/arrow from taking an errant shot on target, it is common to employ one of a variety of targeting and/or release devices which allow the bow hunter to quietly aim and deliver an arrow with a relatively high degree of accuracy, whether aiming at a target or animal.

Archery is impacted by even the smallest of variations at the time of release. Even small motions can affect the aim and trajectory of the arrow, including inhalation/exhalation, a shaking hand, and/or unintentional twitch of a finger or jerk of an arm. That is, angular deviations exacerbate long-range shots inasmuch as the effects of lateral deviation increase dramatically as the longitudinal distance increases. It is for this reason, that a long-range shooter either stops breathing or exhales upon release.

The archery enthusiast is also given a variety of targeting release aids for improving the accuracy of an arrow's trajectory. FIGS. 1a and 1b depict a prior art release aid 100 which employs a strap 102 to connect the release mechanism 100 to an archer's wrist or arm. The release aid 100 employs a single jaw 104 which pivots toward, and against, a cinch or stop 106 to capture/engage a loop formed in combination with the drawstring 110 of the bow 120. An example of a single jaw release mechanism is shown in Jones U.S. Pat. No. 8,146,578. One of the principle disadvantages of such a release aid 100 relates to its inability to accommodate an archer's lateral motion at the moment immediately prior to release of the drawstring 110. As shown in FIG. 1b, if an archer jerks his/her hand slightly in a lateral outward direction LD1, the static stop 106 will move the drawstring 110 in the same direction LD1. The laterally displaced drawstring 110 can change the direction of the arrow, resulting in decreased shooting accuracy.

Other release mechanisms, such as those disclosed in Jones U.S. Patent Publication 2013/0174821 and Jones U.S. Pat. No. 8,746,223 include a dual jaw release which open along a central plane. The dual jaw of these “caliper release” mechanisms are symmetric about a central bifurcating plane or open symmetrically relative to the bifurcating plane. While these release mechanisms offer the advantage of a rapid release, they do not allow the drawstring to move freely over the jaws upon release. As such, they too can impart an undesired lateral displacement and adversely impact shooting accuracy.

The foregoing background describes some, but not necessarily all, of the problems, disadvantages and shortcomings related to archery release aids of the prior art.

Additional features and advantages of the present disclosure are described in, and will be apparent from, the following Brief Description of the Drawings and Detailed Description.

DETAILED DESCRIPTION

FIG. 2 depicts a perspective view of a compound bow 10 having a draw string or bow string 12 drawn through upper and lower cams 14a, 14b mounted at the end of each bow limb 16a, 16b. While an embodiment of the archery release device 20 is shown in the context of a compound bow 10, it will be appreciated that the device 20 may be used to assist targeting of any basic, recurved, compound or longbow, or any other type of string-based shooting device. In the illustrated embodiment, an archery release device 20 engages a secondary recurved loop string 22 connecting to the primary bow string 12 at two positions 24a, 24b (FIG. 3), i.e., one above and the other below the desired location for receiving the arrow 18. While the archery release device 20 is used in combination with a recurved loop string 22, i.e., to preserve the life and integrity of the primary bow string 12, it will be appreciated that the release device may engage the primary bow string directly. The archery release device 20 includes an arm strap, wrist strap or harness 28 for the purpose of supporting the release device 20 while targeting and releasing the bow string 12. In one embodiment, the archery release device 20 includes components/elements which assist in: (i) drawing an arrow 18 against the bow string 12 of an archer's bow, (ii) holding the arrow 18 for a period of time while a target is acquired, and (iii) releasing the arrow 18. Accordingly, in other embodiments (not shown), the archery release device may include grippers, claspers, pinchers or jaws which directly engage the arrow 18 and hold it in position. In such embodiment, the archery release device may, or may not, include a strap, belt or cord to secure the archery release device to the operator/archer.

In FIG. 4, the harness 28 of the archery release device 20 is formed by a right-angled, V-shape wrist strap or belt 30 which is fed through, and secured to, a conventional wrist or belt buckle 32. The harness 28 is configured to fit around the wrist or forearm of the operator/archer. In the described embodiment, an aft end of the archery release device 20 is pivotally or articulately mounted to the harness 28 about axes 34a, 34b to facilitate motion about at least two orthogonal axes. That is, the connection between the harness 28 and the aft end of the release device 20 may include a pair of hinge-mounts, i.e., rotationally mounting about each of the pivot axes 34a, 34b, or a spherical ball and socket mounting arrangement.

In FIGS. 5 through 10, the archery release device 20 includes a release body 40, a jaw assembly 60 and a trigger 80. The release body 40, best shown in FIGS. 6 through FIG. 9, has a substantially cylindrical/tubular shape at a first end 42 which transitions to a clevis at an opposite or second end 44 thereof. A cylindrical bore 46 is formed, or machined, through the first end 42 which opens into a cavity 48 formed in the second end portion 44 of the release body 40. As will be discussed in greater detail hereinafter, the cylindrical bore 46 is configured to guide the linear travel of a tubular shaped member such as a shaft, cylinder, tube or piston (see FIG. 10) which controls the position of the trigger 80, i.e., changing the position of the first and second jaws 60a, 60b from a closed position or condition (i.e., pre-release or ready position) to an open position or condition (i.e., a release or actuation position.)

The clevis end 44 of the release body 40 includes first aligned apertures 54a, 54b configured to receive first and second jaw supports or pins 62a, 62b (see FIG. 10) for pivotally mounting the jaw assembly 60 to the release body 40. While the cylindrical bore 46, disposed at one end of the release body 40, guides a spring-biased piston 86, the cavity 48 receives: (i) an actuation end AE of the jaw assembly 60, and (ii) the trigger 80 for actuating the jaw assembly 60, at the other end. Finally, the release body 40 includes a pair of guide surfaces or aligned slots 58a, 58b which extends through a side wall, or the clevis end, of the release body 40. The aligned slots 58a, 58b receive an axle 90 (see FIG. 10) extending through a pair of clevis lugs 91a, 91b on each side of the piston 86. The axle 90 also retains a center roller bearing or sear 92 between the lugs 91a, 91b of the piston 86. The sear 92 engages a surface of the trigger 80 and functions to bias the trigger 80 into a closed or ready position. In this embodiment, the lease body 40 guides the first compression spring 88 along at least one of the guide surfaces 58a, 58b which is substantially linear to the axis 90. The first compression spring 88 is biased along this axis 90 and is configured to prevent the introduction of a bending moment into the first compression spring 88 upon actuation of the first and second jaws 60a, 60b. These features and components will become clear when describing the internal components of the archery release device 20 shown in FIGS. 11 and 12.

The first and second jaws 60a, 60b of the jaw assembly 60 each include a jaw end portion JE opposite the respective actuation end portion AE. Each of the jaws 60a, 60b pivots independently of each other about a jaw support. In the described embodiment, the jaw support for one of the jaws 60a, 60b includes a first pin 62a and the jaw support for the other of the jaws 60a, 60b comprises a second pin 62b. Furthermore, the first and second jaws 60a, 60b are positionable/changeable from the closed position (FIG. 11) to the open position (FIG. 12). In the described embodiment, the first and second jaws 60a, 60b are spring-biased to the open position by a second compression spring 98. In the described embodiment, the second compression spring 98 seats within a cavity of the jaws or is held between the jaws 60a, 60b by a transverse pin projecting into the coil opening of the compression spring 98. In another embodiment, the first and second jaws 60a, 60b may be torsionally-biased about their respective axes 64a, 64b to remain in the open position. Alternatively, the first and second jaws 60a, 60b may open without the assistance of a coil or torsion spring, but may open solely in response to motion of a trigger mechanism.

The jaw end portion JE of each of the first and second jaws 60a, 60b is configured to move in a lateral direction in response to forces imposed by a drawstring portion of the bow. More specifically, jaw 60a is configured to move in an inward lateral direction I-LD (see FIGS. 2, 11 and 12) in response to an inward lateral force conveyed by the drawstring 12 of the archery bow 10, caused by a sudden outward lateral motion of the archer's arm (not shown). On the other hand, jaw 60b is configured to move in an outward lateral direction O-LD in response to an outward lateral force conveyed by the drawstring 12 of the archery bow 10, caused by a sudden inward lateral motion of the archer's arm. It should be appreciated that the drawstring portion of the bow may include the bow string 12 or a loop 22 (see FIG. 3) connecting at two points to the bow string 12. It should also be appreciated that jaws of different size or geometry will respond differently to these lateral motions, which may differ in rate and magnitude.

The actuation end AE of each of the first and second jaws 60a, 60b engages one or more over-center release or actuation steps 82, 84 formed in the trigger 80. Each of the actuation ends AE includes an interface portion, roller bearing or sear 70, operative to engage a respective surface or actuation step 82, 84 of the trigger device 80, wherein the surfaces 82, 84 extend along different axes 83, 85, respectively. It will be understood that the actuation steps 82, 84 function to allow independent operation or movement of the respective first and second jaws 60a, 60b, and, consequently, independent release of the drawstring 12 from the jaws 60a, 60b. The actuation steps 82, 84 trigger the release device 10, i.e., to release the loop string 22 of the bow 10. In addition to triggering the release of the bow string 12, the actuation steps 82, 84 function in an actuation capacity wherein the apex AX of the respective actuation steps 82, 84, bias the trigger 80 in a clockwise or counter-clockwise direction about a pivot axis 94A of a pin support 94. That is, once a sear 70 rolls over the apex AX of one of the actuation steps 82, 84, the trigger 80 is biased in one rotational position or in the opposite rotational position about the pivot axis 94A.

The trigger 80 rotationally mounts to the release body 40 about the pin support 94 which pivots within the second aligned aperture 56 of the release body 40. The trigger 80 defines the actuation steps 82, 84 which are disposed between the actuation ends 62a, 62b of the first and second jaws 60a, 60b. In the described embodiment, the rollers or sears 70 of each of the actuation ends 62a, 62b function to engage, roll-up and over the actuation steps 82, 84 of the trigger 80. While the illustrated embodiment shows two (2) actuation steps 82, 84, it should be appreciated that only one release step 82, 84 may be employed. It should also be appreciated that jaws 60a, 60b may be of a different size, e.g., the lengths between a pivot axis 64a, 64b and the respective sear axis 70a, 70b may differ to actuate at different rates.

The trigger 80 is biased in a counter-clockwise direction about its pivot axis 94 by a first linearly-guided compression spring 88. More specifically, the first compression spring 88 engages the piston 86 which is guided within the linear bore 46 (see FIG. 8) formed in the release body 40 of the release device 20. The piston 86 is, in turn, guided by, and within, the aligned linear slots 58a, 58b machined within the side walls or clevis end of the release body 40. With respect to the latter, the axle 92 extends through and projects outwardly from the clevis lugs 91a, 91b of the piston 86 to engage the linear guide slots 58a, 58b. The linear slots 58a, 58b also function to rotationally fix the vertical axis VA of the piston 86. Accordingly, the first compression spring 88 is not subject to bending moment loads which would, otherwise, reduce the service life of the trigger 80.

While the described embodiment depicts a piston 86 configured to receive and retain a roller sear 90 at one end which is guided within linear guide slots 58a, 58b of the release body 40, it will be appreciated that other arrangements are contemplated. For example, the piston 86 may be guided within a keyway formed within linear bore 46 of the release body 40. Furthermore, while the piston 86 is shown to include a cavity for receiving one end of the first compression spring 88, it will be appreciated that the compression spring 88 may circumscribe a shaft (not shown) which functionally replaces the piston 86 within the bore 46 of the release body 40. Accordingly, the upper end of the shaft would necessarily transition to form a T-shaped cross-member for engaging the guide slots 58a, 58b. Alternatively, the shaft may comprise telescoping members which are internally biased by a compression spring. A first end of the telescoping shafts may articulately mount to the underside of the trigger 75 while the opposite end may articulately mount internally to a base portion of the release body 40.

Geometrically, the first and second jaws 60a, 60b are asymmetric about a plane P1 located between the pivot axes 64a, 64b of the jaws 60a, 60b. This may be achieved by varying the length or angle of the actuation arm 70 relative to the trigger release-step 84. For example, in the closed position, and referring to FIG. 11, the angles β1 and β2 between the bifurcating plane P1 and the actuation end 70 of the respective one of the jaws 60a, 60b are unequal or different. That is, the angle β1 between the bifurcating plane P1 and the actuation plane P2a, i.e., a plane containing the pivot axis 64a and the sear axis 70a associated with the first jaw 60a, is about twenty degrees (20°). On the other hand, the angle β2 between the bifurcating plane P1 and the actuation plane P2b, i.e., a plane containing the pivot axis 64b and the sear axis 70b, is about fifteen degrees (15°). Accordingly, in the closed position, the angular difference, therebetween is about five degrees (5°).

In the open position, and referring to FIG. 12, the angles β1 and β2 between the bifurcating plane P1 and the actuation end 70 of the respective one of the jaws 60a, 60b, are also unequal or different. Immediately following release, the angle β1 associated with the first jaw 60a is about twelve degrees (12°) and the angle β2 associated with the second jaw 60b is about zero degrees (0°). Accordingly, in the open position, the angular difference, therebetween is about twelve degrees (12°).

Asymmetry may also be achieved by employing jaws 60a, 60b of different size and shape. For example, in FIG. 13, the jaws 60c, 60d may be configured such that the length between a pivot axis 64a, 64b and the respective sear axis 70a, 70b differs to effect a different rate of actuation. More specifically, in FIG. 13, the release-step 84 of the trigger 80 is distally spaced from the pivot axis 94 of the trigger 80. Furthermore, the actuation end AE of jaw 60d curves or bends outwardly such that when the sear rolls up and over the release step 84, the jaw 60d opens wider and, depending upon the spring rate of the biasing coil spring (not shown), and spreads more rapidly.

In FIG. 14, the shape of the jaws 60f, 60g may be asymmetric to affect the placement of the drawstring release loop 22 within the jaws 60. For example, the jaw release surface JRS of the first jaw 60f may curve outwardly while the release surface JRS of the second jaw 60g may slope slightly away from the pivot axis 64b to facilitate a smooth release of the drawstring.

In operation, the trigger 80 is actuated by engaging the release arm 75, i.e., by rotating the arm 75 in a clockwise direction against the linear force of the first compression spring 88. The trigger device 80 causes the actuation ends 62a, 62b of each of the respective first and second jaws 60a, 60b to engage the corresponding one of the actuation steps 82, 84, formed on the trigger device 80. Actuation of the trigger device 80: (i) opens/releases the drawstring 12 of the archery bow 10, and (ii) releases the jaw assembly 60 such that the first and second jaws 60a, 60b may pivot independently and/or freely. That is, each of the first and second jaws 60a, 60b may be displaced independently, in a lateral direction, in response to a lateral force applied or imposed by the drawstring portion of the archery bow.

More specifically, the first and second jaws 60a, 60b are initially engaged with each other to hold a drawstring portion of the bow in the closed position. The jaws 60a, 60b are at least partially disengaged from each other to release the drawstring portion in an open position. The jaws 60a, 60b are biased closed by the linear compression spring 88 acting on the trigger 80 while the first and second jaws 60a, 60b are biased against the force of the first compression spring 88 by the second compression spring 98 acting between the first and second jaws 60a, 60b. The relative strength of the opposing forces imposed by each of the first and second compression springs 88, 98 determines the relative ease or difficulty with which the trigger 80 actuates the release or opening of the first and second jaws 60a, 60b.

In summary, the jaws 60 of the release mechanism 20 may pivot along the same or different axes, are geometrically asymmetric and are free to pivot independently immediately following release of the trigger mechanism. More specifically of the actuation steps 82, 84 determine how the first and second jaws 60a, 60b open in response to actuation of the trigger device 80. The linear force produced by the second compression spring 98 acting between the first and second jaws 60a, 60b determines the force necessary to reset the trigger device 80 and the first and second jaws 60a, 60b to a closed position. The guided piston 86 prevents moment loads from acting on the first compression spring 88 to improve the dynamic response of the trigger device 80. Finally, upon actuation of the trigger 80, the first and second jaws 60a, 60b are essentially free to move independently. As such, the drawstring 12 (see FIG. 3) can be released: (i) without resistance from either one of the first and second jaws 60a, 60b, (ii) without being hung-up on one of the first and second jaws 60a, 60b, and (iii) without being influenced by the rigidity of one, or the other, of the first and second jaws 60a, 60b. That is, the actuation steps 82, 84 allow the first and second jaws 60a, 60b to move independently which, in turn, allows the drawstring 12, or drawstring loop 22, to move past the jaws 60a, 60b with as little resistance/disturbance as possible. Accordingly, should the archer suddenly and unintentionally jerk or twitch his/her wrist or arm at the moment immediately prior to release, the affected one of the jaws 60a, 60b will freely pivot independent of the other of the jaws 60, 60b. This pivot motion/reaction eliminates or reduces undesirable lateral pulling on the bow string 12, which, in turn, improves shooting performance and flight of an arrow 18 released from an archery bow.
