(17) Generally, the apparatus 10 includes a foothold 158 mechanism that essentially allows energy-storing rubber bands 212 to be extended with the power of one (1) or two (2) hands. The rubber bands 212 are retained in a ready-to-fire position by a set of retaining fingers 116, 134 in an action 70 while a user takes a careful aim at an intended target with the assistance of an included laser pointer 166. After releasing a projectile 300 from the action 70, another projectile 300 can be removed from a projectile storage cavity 62 provided in a stock 20 of the apparatus 10 to prepare for an ensuing release.
(18) Referring to
(19) The stock 20 is configured to generally be a traditional single-piece gunstock, having a butt 22 with a thumbhole 58, and a fore-end 24. The stock 20 may be composed of any of a variety of hardwood typically utilized for that purpose such as ash, oak, maple, or walnut, and could even include any exotic wood, such as rosewood, or teak. Other materials, such as cast metals, composite materials, or thermoplastics, may also be utilized without limiting the scope of the present disclosure. The wood, or other constituent material, of the stock 20 may be finished with any acceptable coating, or plating material, as may suit the taste of a particular user.
(20) The butt 22 is configured to have an elliptical, or modified elliptical, cross-section. It is understood that alternate embodiments may incorporate other cross-sectional shapes without limiting the scope of the present disclosure. In one (1) embodiment, the butt 22 is provided with a notched comb 26 terminating at a heel 28 located at an upper extent of a proximal end of the butt 22. This proximal end of the butt 22 is curved from the upper heel 28 to the toe 32 so as to comfortably conform to the chest and upper arm of a user when the apparatus 10 is tucked against the shoulder in one (1) method of use.
(21) The butt 22 tapers toward the approximate middle of the stock 20 from the toe 32 to the location of a grip 34. The grip 34 is configured to have a steeper angle cut into the butt 22 for more precise control of the apparatus 10 by a firing hand. The grip 34, in combination with the contoured thumbhole 58 presents a more natural position of a user's firing hand relative to their arm.
(22) Referring to
(23) A cap 64 is intended to be inserted into the open end of the projectile storage cavity 62 so as to retain the projectiles 300 for a future use. The cap 64 and the projectile storage cavity 62 may be provided with complimentary threads of any form so as to render the cap 64 removable. Other methods, such as an interference fit, may also be utilized for the retention of the cap 64 within the projectile storage cavity 62 without limiting the scope of the present disclosure.

(25) The slide member 152 is composed of an aluminum alloy to advantageously exploit the low density of that material in comparison to other metals. The slide member 152 is provided with a smooth crest 154 along an upper planar face. A lower side of the slide member is provided with a plurality of detents 156 (see
(26) The slide cavity 66, and the slide member 152, are covered by a top plate 42 as a serviceable access to, and manner of assembly for, the slide member 152 and the action 70. The top plate 42 is adapted to have an appropriate cross-section along the length so as to adequately fill any gaps that may exist between the slide member 152, the slide cavity 66, the action 70, and an action cavity 36 (see

(32) The rubber bands 212 are composed preferably of a natural, or synthetic, rubber that has been vulcanized to cross-link the polymer chains and improve other mechanical properties. The firing yoke 202 is configured with the double end 206 on each yoke arm 204 so as to support the utilization of two (2) rubber bands 212 at each side of a pouch 214.
(33) The pouch 214 is composed of a split leather of approximately three inches (3 in.) in length. The pouch 214 is provided with a plurality of pouch apertures 216 along each side edge to which the rubber bands 212 may be secured by any appropriate means.

(37) A generally cylindrical firing pin 94 is installed between the front plate 82 and the rear plate 86, having a first end 98 projecting through the rear plate aperture 88 and a second end 100 projecting through the front plate aperture 84.
(38) A flange 96, configured to be an annular ring, is disposed near the first end 98 of the firing pin 94. The flange 96 is operationally located between the front plate 82 and the rear plate 96. The diameter of the flange 96 is larger than the second plate aperture 88 so as to prevent the front of the firing pin 94 from passing through the second plate aperture 88.
