DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

(21) With reference to the drawings, the invention will now be described in more detail. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which the presently disclosed subject matter belongs. Although any methods, devices, and materials similar or equivalent to those described herein can be used in the practice or testing of the presently disclosed subject matter, representative methods, devices, and materials are herein described.

(22) Referring to FIG. 1, a slingshot shown generally at 10 includes a handle 12. The handle include a concave portion 14 and a beavertail 16 to better fit the user's hands. Finger indentions 18 can be included in the front portion of the handle. The beavertail can be used to improve the fit of the handle in the user's hands and also to equally distribute the forces of the handle against the users hands when the bands are under strain which can results in a better grip and safer hold.

(23) The fork 20 is removably attached to the handle and secured by a fork securing assembly. The fork securing assembly can include a spring 22 attached to the lower end of the handle that is operatively associated with the fork at a securing extension 24. When the fork is attached to the handle, the securing extension can engage with the spring to secure the fork to the handle with a notable audible indication that the fork is securely attached. In one embodiment, the notable audible indication is a click produced by the spring “snapping” due to a recess in the handle. This provide a safety feature by indicating that the fork is secured to the handle. The spring can be secured to the bottom of the handle with one or more screws 26a and 26b in one embodiment.

(24) The fork can include fork arms each having a lateral opening 28a and 28b. The opening of each fork leg can received one end of the band and a plug 30. The bands can include a pad for holding ammunition such as projectiles and arrows. In one embodiment, the plug can include a bore that can receive a stopper or other element to increase the diameter of the plug to add extra security for securing the band to the forks. For example, when the band is made from thin latex.

(25) An arrow rest 32 can be attached to the fork so that it is disposed between the forks and secured to the forks by a mounting bracket or bracket 34. The bracket can be attached to the forks by bolt 35 which is received through the bracket and into an insert 36. A pair of bolts and inserts can be used in one embodiment. The bracket is secured to the fork at two lateral positions to assist keeping the arrow rest parallel with the forks during use. The bracket is arranged to provide sufficient clearance so as not to interfere with the operation when shooting an arrow. The bracket can also prevent the bands from passing through the arrow rest in operation. Arrow rest extensions (33 of FIG. 18) can be included on the forks to position the arrow rest forward the forks to further assist with providing sufficient clearance.

(26) A wrist brace 38 can be removably attached to the handle through bolt 40 and brace plate 42 so that the wrist brace can have a horizontal position and a vertical position. The heel can include lateral lower stops 31a through 31b to support the hand when held by the user as shown in FIGS. 20A and 20B. The wrist brace can also fold forward for a compact footprint for transportation, storage and the like.

(27) Referring to FIG. 2, the handle is shown in one embodiment to include finger indentions 18. The spring can include serrated portion 44 allowing a better grip on the spring to push it laterally to release the spring from the fork. Spring tab 46 engages the securing extension to secure the fork to the handle. The handle can include a front radiused portion 48, transition portion 50 and upper portion 52 included on the front face of the handle in one embodiment. A rear radiused portion 54 can be included on the rear of the handle. A heel 56 can be included in the handle attached to the bottom of the handle. Brace slot 58 can be defined in the handle to receive the wrist brace. Brace opening 60 defined in the handle can receive bolt 40 to secure brace plate 42 to the handle. The handle can include a honeycomb portion with indentions defined in the handle to reduce weight and increase grip. This pattern can include safety the manufacturing process by reducing the mass of the component such as in injection molding. In one embodiment, a mounting rail, such as a weaver or picatinny rail, can be included on the bottom of the handle and can be attached to the heel. The rail allow for the attachment of other articles such as lights, laser aiming devices, ammunition holders, optics, and the like. The bottom portion of the handle can be removed in one embodiment so that the opening that receives the wrist brace or its securing assembly can be used to secure a lanyard to the handle to improve safety.

(28) Referring to FIG. 3, the handle includes a saddle 64 defined in the handle to receive the forks. The saddle can include a ridge 66 that generally runs along a ridge in the middle of the saddle resulting in a convex front face 68 and convex rear face 70. The convex rear face can include an rear curvature larger than a front curvature of the convex front face to maximize contact with the fork and support the rearward force from the fork when the invention is in use. In one embodiment, the distance between the two faces 72 is smaller along cross-section A than the distance 74 between the two faces along cross-section B. A thumb recess 76 can be defined in the handle to assist with releasing the spring allowing the front fork to be removed. This configuration reduces “play” between the forks and handle, especially after wear due to friction between the forks and the handle from use.

(29) Referring to FIG. 4, the fork 20 is shown with a rear concave portion 86 that engages the convex rear face of the handle when the fork is placed in the handle. The spring engaged a curved portion 88 of the securing extension forcing the spring laterally outward from the handle when the fork is pressed on the handle. When the fork is fully inserted, the spring tab is received into tab area 90 of the fork and contacts the top of the securing extension to secure the fork in place. The securing extension can include a recess 92 to allow the spring to move laterally in its recess when the fork in place.

(30) Referring to FIG. 5, the handle can include an upper spring recess 78 for receiving the spring in a secured position for securing the fork to the handle. When the fork is pressed into the handle, the spring can produce an audible indicator (e,g, snap or clink) that the fork is properly seated. This indicator is enhanced by the upper spring recess. A mounting recess 80 can include opening 84a and 84b for receiving bolts that secure the spring to the handle. The bolts can be received in openings in the spring and secure to the handle. A ramp 82 can be included to provide differing depths of the mounting recess and the upper spring recess.

(31) Referring to FIG. 6, the fork extension 96 can include a rear concave portion that engages the convex front face of the handle when the fork is placed in the handle such as when the fork extension is received in the saddle. In one embodiment, the forks can include aiming points or reference points 94a and 94b on the outer lateral edges of the fork openings 28a and 28b. The reference points can assist in aiming the projective fired form the invention. Secondary aiming points 95a and 95b can be included generally at the upper distal ends of the mounting bracket. These reference points can be used when the arrow rest is attached. The mounting bracket can include lateral stops 97a and 97b that extend into a whisker area 99 of the arrow rest and can prevent the band and other attachments to the bands from entering the whiskers prior to the arrow editing the whiskers.

(32) Referring to FIG. 7, the fork is shown secured to the handle. The spring is received in the spring recess are. The spring tab is engaged with the tab area of the fork preventing the fork from moving up and away from the handle during use.

(33) Referring to FIGS. 8 and 9, a plug 30 is shown. A bore 100 is defined in the plug and extending through the plug. Lateral groves 102a and 102b can be included in the side of the plug. Front groves 104a and 104b can be defined in the front side 106 of the plug. The plug can be used with various types of bands such as flat, thick, thin, round, or tubing. The plug can be marked with a thick indicator 108 to show that the thick cone portion 110 is used for think bands. A thin band indicator 112 can be included to indicate that a thin band should be used with the thin cone portion 114 of the cone. The plug can include a radial shoulder that includes an upper shoulder 116 and a lower shoulder 118 in one embodiment. The rear of the plug is shown having a back cap 120.

(34) Referring to FIG. 10, the fork 20 is shown with opening 28a for receiving the plug. A thin band 122 is inserted at direction 126 into the opening so that a portion of the thin band extends out of the opening into the user's side 124. The end of the thin band can travel along path 128 so that the end portion extends through the opening and upwards. The plug is then inserted into the fork opening 28a along path 130. Referring to FIGS. 11 and 16-17, the thin band is then folded over the fork and toward the user's area 124 securing the band into the fork.

(35) Referring to FIGS. 12 and 13, the band securing assembly is shown with a tube 132 being inserted into the opening of the fork and into the bore of the plug along path 136a through 136c. A generally sphere stopper such as ball 134 or other insert can be placed inside a bore in the tubing. The plug is inserted into the opening in the fork. When tension is placed on the band in a direction 137, the ball prevents the band from traveling through the plug thereby securing the band to the fork. In one embodiment, other member can be used to secure the tube into the plug. Referring to FIGS. 19A through 19C, a stopper 200 can be used. The stopper can be of other design other than the ball previously described. For example, the stopper can include a cap 202, resilient member 204, and base plate 206. In one embodiment, the stopper include an expansion member 210. When the stopper is placed in the tubing and the base plate is forced toward the cap in direction 218, the resilient member and expansion member expands to create a diameter larger than the bore and thereby secure the tubing in the plug. The base plate can be forced toward the cap with a threaded member 212, nut 214 or lever 216.

(36) Referring to FIG. 14, the invention is shown when used with a band that is doubled over. In this case, the doubled band 138 is inserted into the opening with the plug between the distal end 142 of the band and the fork. The band then travels in a direction shown as 140a through 140c with the plug so that the band is received in the front and side grooves. Referring to FIG. 15, the doubled band is secured to the fork.

(37) Referring to FIG. 18, the handle 12 is shown held with the arrow rest 32 vertical and generally orthogonal in relation to an arrow. In order to maximize accuracy, the arrow should be 90 degrees in relation to the arrow rest. When the invention is shown as held by a user, a wrist strap 39 can be attached to the wrist brace 38 to prevent the handle from rotating backwards toward the user and increase the ability to apply tension to the bands. The band can be rigid or flexible. In one embodiment, the wrist band can be adjusted to account for varying diameters in the forearms of the users. For example, for a user with a larger diameter forearm, the wrist band can be extended so that the arrow rest is maintained 90 degrees to the arrow to maximize accuracy. Without the ability to adjust the wrist band, the alignment of the arrow rest, forearm, handle ad arrow would not be optimal for accuracy or distance.
