DETAILED DESCRIPTION
(16) A preferred embodiment of a handheld archery release 2 having an angularly adjustable finger bed according to the invention is shown in FIGS. 1 and 2. The release includes a handle 4 which preferably is formed of two concave handle portions or sections. The release also includes a pair of brackets 6 pivotally connected with the handle and a pair of finger beds 8 pivotally connected with the brackets. Together, the brackets and finger beds provide width and angular adjustment to the finger support portion of the release. The assembled archery release is shown in FIGS. 2a-2i.
(17) The handle of the release is shown in FIGS. 3a-3f. As shown therein, the handle has a longitudinal axis and includes top 10, bottom 12, front 14 and rear 16 portions and side 18 surfaces. The top portion 10 of the handle contains front 20 and rear 22 spaced contours having a concave configuration, each of the contours supporting a finger of an archer when the archery release is in use. Preferably, the front contour supports the index finger of the archer and the rear contour supports the middle finger of the archer. Between the front and rear contours is a head 24 on which a bail (not shown) is mounted to hold and release a bowstring. The handle is preferably formed of two mating halves which define a cavity therein and are joined with screws or other fasteners as is known in the art. A sear, not shown, is arranged within the handle cavity and is operable to release the bail when the release is operated to fire a shot.
(18) Each side of the handle contains recess 26 below the front contour 20 for receiving a portion of a bracket. The handle further contains an opening 28 in the front wall 14 configured to receive a dowel pin 30 which is retained in the opening via a plug screw 32. The dowel pin and plug screw are shown in FIG. 1.
(19) The brackets 6 for connecting the finger beds 8 with the handle 4 have the same configuration. One of the brackets is shown in detail in FIGS. 4a-4i. The bracket has a generally U-shaped configuration to define a contour 34 which matches the front contour 20 of the handle. The bottom of the bracket includes a spaced pair of projections 38a, 38b which terminate in laterally extending supports 40. The bottom of each bracket is arranged in the recess 26 in the bottom area of a side of the handle. Each bracket projection has an inner surface which faces the handle and an outer surface. The inner surface contains a tapered recess 42 as shown in FIGS. 4e and 4f. Each bracket projection further contains aligned openings 44 configured to receive the dowel pin 30 about which the brackets may pivot relative to the handle. The bracket projections 38a, 38b further contain second openings 46a, 46b, respectively. However, the second opening 46a in projection 38a is a through opening while the second opening 46b in the projection 38b is a partial opening. These openings 46a, 46b are also aligned and are configured to receive a dowel pin 48 as shown more particularly in FIGS. 1, 6a and 6b.
(20) The brackets 6 form part of a drive assembly for moving the finger beds 8 relative to the handle 4 in order to adjust the width of the effective finger beds. Another part of the drive assembly is a toggle clamp 50 which is arranged within the handle recesses.
(21) The toggle clamp is shown in detail in FIGS. 5a-5g. It includes upper 50a and lower portions 50b and is configured to fit within a bottom portion of the handle cavity between bottom portions of the brackets 6 as shown more particularly in FIGS. 6a and 6b. The upper portion 50a extends beyond the bottom portion 50b in the longitudinal direction. The upper portion preferably includes curved or convex side edges 50c as will be explained in greater detail below. The lower portion 50b contains a longitudinal through opening 52 and a threaded opening 54 in the bottom surface of which extends normal to the longitudinal direction of the through opening. The through opening 52 preferably has an oval configuration. It is configured to receive the dowel pin 30 when it is arranged in the handle cavity. Owing to the oval configuration of the opening 52, the toggle clamp is displaceable within the handle cavity relative to the dowel pin. A width adjustment screw 56 is threadably connected with the toggle clamp via the threaded opening 54.
(22) The bottom portion 12 of the handle 4 contains a through opening 58 through which the width adjustment screw 56 passes for connection with the toggle clamp lower portion threaded opening 54 as shown in FIGS. 1, 6a and 6b. Rotation of the width adjustment screw displaces the toggle clamp within the handle in a direction normal to the longitudinal axis. In this regard, the curved edges 50c of the toggle clamp upper portion 50a slide within the recesses 42 in the inner surface of each bracket 6. As the width adjustment screw 56 is tightened, the toggle clamp moves toward the bottom of the handle and slides within the bracket recesses to pivot the brackets about the dowel pin and extend the upper portions of the brackets from the handle to an extended wider position. Conversely, as the width adjustment screw 56 is loosened, the toggle clamp moves toward the top of the handle, sliding within the bracket recesses to pivot the brackets about the dowel pin and retract the upper portions of the brackets toward from the handle to a retracted narrow position.
(23) Set screws 60 pass through openings in the handle bottom surface on opposite sides of the opening 58 to engage the respective dowel pins 48 as shown in FIGS. 1, 6a, and 6b. The set screws must be loosened before width adjustment of the brackets is made. The set screws are then locked down by putting pressure onto the dowel pins 48 located in the brackets which in turn pushes pressure between the radii located on the toggle clamp and the bracket angular surfaces within the recesses 42 resulting in opposing pressure between the width adjustment screw 56 and the lock down set screws 60 to keep the width adjustment in place. That is, the set screws 60 must be tightened in order for the angular surfaces of the brackets to maintain contact with the underside radii of the width toggle clamp. The two set screws are integral to affixing the width since there is no spring maintaining contact of the toggle clamp underside radii with the angular surface of the brackets. The set screws define the opposing force of the width adjustment screw to lock the width adjustment of the brackets in place.
(24) As noted above, finger beds 8 are pivotally connected with the brackets 6. The finger beds are shown in detail in FIGS. 8a-8h. Each finger bed has a generally rectangular configuration with a concave upper surface 62 corresponding with the front contour 20 of the handle portion. That is, the concave surfaces of the finger bed and the front contour of the handle portion are aligned. The front surface of the finger bed contains a tapered recess 64 extending from the concave upper surface toward the bottom portion of the finger bed. Preferably, the tapered recess terminates short of the bottom portion. The depth of the tapered recess decreases from the top portion to the bottom portion and the longitudinal length of each tapered recess also decreases in the direction of the bottom portion. Preferably, the length of the upper portion of each tapered recess extends a longitudinal length equal to the longitudinal length of the front contour of the handle portion. The tapered recess thus has a scalloped configuration.
(25) Each finger bed further includes front 66 and rear 68 surfaces. At the top portion of these surfaces, a pair of nubs or stubs 70 extend along a finger bed axis parallel to the longitudinal axis of the handle. The stubs are configured to fit within fittings in the top portion of the brackets. More particularly, one side at the top of the bracket contains a through hole 72 and the other side of the top of the bracket contains a contour 74. One stub of the finger bed is arranged in the through hole and the other stub of the finger bed is arranged in the contour, preferably via a snap-fit connection so that the finger beds swing freely within the bracket opening and contour so that the finger bed pivots about an axis parallel to the longitudinal axis. As such, the top portion of each finger bed is pivotally connected with the top portion of the corresponding bracket while the bottom portion of each finger bed moves toward or away from the handle portion.
(26) Each finger bed 8 further includes a projection 76 which extends rearwardly from a bottom portion thereof toward the bracket with which the finger bed is connected. Each bracket projection 38b contains a slot 78 to receive the projection. The projection extends freely through the slot during pivotal movement of the finger bed relative to the associated bracket. However, a locking mechanism is provided to lock the finger bed in a selected angular orientation relative to the bracket as selected by the archer.
(27) Referring to FIGS. 9 and 10, a preferred locking mechanism for the finger bed will be described. The bracket projection 38b contains a threaded opening 80 configured to receive a lock screw 82. The end of the screw within the projection is configured to engage the finger bed projection 76. When the screw is tightened, it presses against the finger bed projection and locks it in place relative to the bracket, thereby locking the finger bed in a selected angular position.
(28) To adjust the angle of the finger bed, the archer loosens the screw 82 to release it from the finger bed projection. The archer then manually pivots the finger bed to a desired angle relative to the bracket. Once positioned, the screw is then tightened against the finger bed projection to lock the finger bed in position.
(29) In accordance with the invention, an archery release is provided with finger supports which are adjustable in both width via operation of the width adjustment screw 56 to pivot the brackets relative to the handle and angle via release of the set screws 82 so that the archer can manually pivot the finger beds relative to the brackets.
(30) FIGS. 11a-11d show the archery release 2 with the brackets and finger beds 8 in a narrow width position with the finger beds adjacent to the brackets.
(31) FIGS. 12a-12d show the archery release 2 with the brackets and finger beds 8 in a narrow width position with the finger beds angled outwardly from the brackets.
(32) FIGS. 13a-13d show the archery release 2 with the brackets and finger beds 8 in a wide width position with the finger beds adjacent to the handle sides.
(33) FIGS. 14a-14d show the archery release 2 with the brackets and finger beds 8 in a wide width position with the finger beds angled outwardly from the brackets.
(34) While the preferred forms and embodiments of the invention have been illustrated and described, it will become apparent to those of ordinary skill in the art that various changes and modifications may be made without deviating from the inventive concepts set forth above.
