(34) Referring to FIG. 1 (Prior Art), the view of the known slingbow is presented with its own referral numerals.

(35) Referring to FIGS. 2-4, an improved slingshot 1 comprises a handle 2, a subhandle 3, a first sling member 4, a second sling member 5, a vertically adjustable directional member for arrow projectiles (a vertically adjustable arrow support) 6, including a body 7 and a ring 8, located in an upper portion 71 (FIGS. 14 and 16) of the body 7, an upper portion 9 of the first sling member 4 and an upper portion 10 of the second sling member 5. In the FIG. 2 a horizontal axis 30, which is perpendicular to the vertical axis 32 and perpendicular to an axis of shooting 34 in a direction of shooting 33 (FIGS. 5 and 6), is shown at its nominal (normal/regular) position when an angle =0, wherein the angle is the angle between an adjusted axis 31 (FIG. 3) and horizontal axis 30 (FIG. 2). The nominal (normal/regular) position (=0) of the vertically adjustable directional member 6 for arrow projectile is mostly appropriate for the arrow shooting at the target (not shown) located preferably not so far from the shooter (sling operator) when the arrow gravitational effect may be not seriously considered, but if the target is located at the significant distance from the shooter, the directional member (the arrow support) 6 can be vertically adjusted, as it is shown in FIG. 3. Depending on the target distance from the shooter and coefficient (constant) of resilience of the first 35 and second 36 elastic members (FIGS. 5 and 24), the adjustment of angle may generally be in the range from 1 to 5 (=1.fwdarw.5) or for some far away targets even slightly higher than 5. In order to provide the angle >0 (FIG. 3), the vertically adjustable directional member 6 is slightly unscrewed from the handle insert 12 in the direction 72 (FIG. 3), i.e., slightly unscrewed from its nominal position when =0 (FIG. 2). For such purpose, the fine thread for the outer thread 11 of the body 7 and the inner thread 13 of the handle insert 12 can be used too.

(36) It is known from many sources of the physics and mechanics that the maximal projectile velocity depends upon resilience of the material [e.g., strength of elastic members (bands/rubber) 35 and 36]. Such effect can be described by the following equation:
V=.sub.1(k)(1) wherein: Va velocity; .sub.1a symbol of function (functional); ka coefficient (constant) of resilience of the used elastic material for first 35 and second 36 elastic members.

(37) As it is also known, the kinetic energy depends upon mass and velocity. Such dependence can be mathematically described by the equation:
E.sub.K=.sub.2(m,V)(2) wherein: E.sub.Kkinetic energy; .sub.2symbol of function (functional); ma mass,
and, as it is known, the kinetic energy E.sub.K is equal to the work W.sub.S for shifting (moving) subject (body) from its initial position at rest. This can be mathematically described as:

(38) $\begin{array}{cc}\begin{array}{c}{E}_K\\ W_S\end{array}\}=f_2\left(m,V\right)& \left(3\right)\end{array}$ wherein: W.sub.Sa work for shifting subject (body) from its initial position at rest in compliance with the known integral/differential formula

(39) $W_S={}_{{}_o}^{{}_n}Fd{}_i$ [wherein: F=k.sub.ia force stretching the resilient material from its initial position .sub.o to the fully stretched position .sub.n for shooting; .sub.oan initial (not stretched) position of the resilient material for; elastic members 35 and 36; .sub.nthe final (stretched position) of the resilient material for elastic members 35 and 36; .sub.i=.sub.n.sub.oa distance the resilient material (e.g., elastic band or rubber 35 and 36) has been stretched, i=0, 1, 2, . . . , j, . . . , n].

(40) The resulting function for the force stretching the resilient material (e.g., rubber of the elastic members 35 and 36) from its initial position to the final stretched position for shooting can be presented as:
F=(m,V,k,.sub.i)(4) wherein: symbol of function (functional).

(41) It is understandable, that not only outer thread 11 of the body 7 of the vertically adjustable directional member 6 can be used for the vertical adjustment of the position of the directional member 6. The other methods of the directional member 6 extension-retraction, for example, such as telescopic principles of the directional member 6 movements up (or down) can be used too. The position of each telescopic section/member (not shown) (if more than two telescopic sections/members/not shown/in the vertically adjustable directional member 6) can be fixed by any reasonable principles and fixative members (not shown), for instance, such as the decorative screw/not shown/, pin/not shown/, etc.

(42) Referring to the most figures, and especially to FIGS. 2-4 and FIG. 11, an improved slingshot 1 is shown of Y-shape with the arms (first sling member 4 and second sling member 5) in U-shape, but it can be in any other reasonable regular or irregular geometrical shape/form.

(43) The upper portions 9 and 10 of the first sling member 4 and second sling member 5 respectively, can be in any reasonable geometrical form/shape, for example, in the L-shape, as it is shown in the FIG. 1 (Prior Art), etc.

(44) The upper portions 9 and 10 of the first sling member 4 and of the second sling member 5 respectively include a first groove 41 and a second groove 42 respectively (FIGS. 2-4). Exemplary, the first 41 and second 42 grooves are shown for the use of a first elastic member 35 and a second elastic member 36 are presented in the circular form of their cross-section (not shown) for coupling with a pouch 43 through a first hole 52 and a second hole 53 respectively (FIG. 23), but the elastic members 35 and 36 can be of the flat form (rectangular form) of their cross-section (not shown) for coupling with a pouch 43 through the first slot 50 and a second slot 51 respectively (FIGS. 21 and 22), or any other reasonable regular or irregular geometrical form/shape (e.g., square form/not shown/, etc.) It should be understandable, that more than two elastic members 35 and 36 can be used to provide more efficiency of the resilient material. Also, it is understandable that elastic members 35 and 36 can be produced, for example, from the synthetic or natural rubber, and the pouch 43 can be produced, for example, from the synthetic or natural leather.

(45) The first sling member 4 and the second sling member 5 are shown in the most figures, especially in FIG. 11, in the circular form of their cross-section (FIG. 11), but they can be of any reasonable regular or irregular geometrical form/shape. The sling members 4 and 5 can be of metallic material or any other reasonably suitable materials.

(46) According to FIG. 5, the improved slingshot also includes a first end 37 and a second end 39 of the first elastic member 35 and a second end a first end 38 and a second end 40 of the second elastic member 36. An aperture 44 is located in the center of the pouch 43 (see also FIGS. 21-23).

(47) Further, the body 7 (FIGS. 2-4, 6-10, 14, 15) of the vertically adjustable directional member 6 comprises an outer thread 11 for coupling with an inner thread 13 of the handle insert 12 having the truncated conic portion 14. The outer surface 15 (see FIGS. 9, 10, 12) of the handle insert 12 can have the ribbed surface (not shown) or rough surface (not shown) in order to be, for example, rigidly glued to the ribbed (not shown) or rough (not shown) inner surface 17 of the handle opening 16 located in an upper portion 69 (FIGS. 2-4, 6-11) of the handle 2. Any other reasonable types of rigid coupling (e.g., threading, welding, hot pressing, etc.) can be used too.

(48) Also, the handle 2 of the improved slingshot 1 includes an inner thread 18, located in a lower portion 70 of the handle 2 (FIGS. 2-4, 6-11), for coupling with an outer thread 19 of the subhandle 3, which comprises a first opening 20 and a second opening 21 (FIG. 4) for insertion of a first arm 22 (FIG. 3) of an arm rest (not shown) and a second arm 23 (FIG. 3) of the arm rest (not shown) respectively in the first opening 20 and second opening 21 (FIG. 4) of the subhandle 3. The subhandle 3 can have a first projection 26 (as an arm rest first arm stopper)/FIGS. 8 and 13/and a second projection 27 (as an arm rest second arm stopper)/FIG. 13/extending from the subhandle 3, thereby limiting further counterclockwise movements of the first 22 and second 23 arms of the arm rest (not shown) after the arm rest (not shown) is resting on the forearm of the shooter (on the forearm of the slingshot's operator). The arm rest (not shown) can be clockwise foldable for compactness. The first 26 and second 27 projections can be rigidly attached (not shown) to the subhandle 3, for example, by glue, screw(s), welding, hot pressing and by any other reasonably suitable principles and methods of coupling. As an example, the subhandle 3 is shown in FIG. 8 with the first projection 26 and first arm 22, but in FIG. 13 the subhandle 3 is shown with the first 26 and second 27 projections, and with the first 22 and second 23 arms of the arm rest [the arms 22 and 23 are also shown in FIGS. 2 and 3]. The projections 26 and 27 of the subhandle 3 can be produced by the molding process during manufacturing of the subhandle 3.

(49) The handle 2 can be also manufactured by the molding process.

(50) FIG. 9 and FIG. 10 depict the handle 2 of the improved slingshot 1 comprising the handle opening 16 for handle insert 12 installation, and the inner thread 18 for coupling with the subhandle 3.

(51) In FIG. 4 the first sling member 4, second sling member 5 and the handle 2 are shown as a solid (entire) part of the improved slingshot 1, but referring to FIG. 11, the first sling member 4 and second sling member 5 can for example be inserted into handle 2. The lower portion 24 of the first sling member 4, and the lower portion 25 of the second sling member 5 can have, for example, the square form or plane form to be rigidly coupled with the handle corresponding openings (not shown) having the analogous square or plane forms respectively. Other types of rigid coupling, for instance such as gluing, threading, welding, hot pressing, etc., can be used too.

(52) Referring to FIGS. 14 and 15, the vertically adjustable directional member 6 is shown with a nut 66 having a texture 67. The nut 66 is intended for fixing position of the vertically adjustable directional member 6 before the shooting by tightening the nut 66 to an upper surface 65 (FIG. 12) of the truncated conic portion 14. The texture 67 is provided for slingshot's operator (shooter) convenience to fix the position of the vertically adjustable directional member 6.

(53) FIG. 16 illustrates another variant of the vertically adjustable directional member 6 for arrow projectiles. According to FIG. 16, the vertically adjustable directional member 6 comprises a first sprang member 28 of the vertically adjustable directional member 6 and a second sprang member 29 of the vertically adjustable directional member 6. The distance D.sub.1 between the first 28 and second 29 sprang members of the vertically adjustable directional member 6 is slightly less than diameter D.sub.2 of the arrow projectile 45 (FIG. 17), i.e.: D.sub.1<D.sub.2. Such correlation of the distance D.sub.1 between the first 28 and second 29 sprang members of the vertically adjustable directional member 6 and diameter D.sub.2 of the arrow projectiles can provide an easy installation of the arrow projectile 45 through the ring 8 (or ring-alike semicircular-style article shown in FIG. 16) of the vertically adjustable directional member 6 for shooting. The material for the ring 8 (FIGS. 2-6, 14, 15) of the vertically adjustable directional member 6, as well as, for the first 28 and second 29 sprang members of the vertically adjustable directional member 6 can be selected from materials having not high coefficient (constant) of friction, for example, such as Nylon, PTFE (polytetrafluorethylene), PVC, etc., especially for the lower (saddle) portion 68 of the ring 8 (FIG. 4, 14, 15, also see FIG. 16), on which the arrow projectile 45 is leaned. Any other reasonably suitable material can be used too.

(54) FIGS. 17-20 illustrate a nock 47 and its coupling with the arrow projectile 45. The nock 47 comprises a nock projection 48, a nock member 49 and a nock middle member 64. The nock member 49 is installable in a rear portion 46 of the arrow projectile 45. The nock 47 can be of solid (entire) configuration, as shown in FIGS. 17-20 (e.g., molded, etc.); or the nock projection 48, a nock member 49 and a nock middle member 64 can be connected to each other, for example by threads, glue, etc. and other reasonably suitable principles and methods of coupling (e.g., welded, etc.)

(55) FIGS. 21-23 are related to a pouch 43. FIGS. 21 and 22 illustrate the pouch comprising a first slot 50 and a second slot 51, and FIG. 23 illustrates the pouch comprising a first hole 52 and a second hole 53 intended for coupling with the different types of the form of the cross-section of the first 35 and second 36 elastic members, as it has been described hereinabove. Again, it is also understandable, that the coupling of the first 35 and second 36 elastic members to the first 41 and second grooves of the first 4 and second 5 sling members respectively can be provided by any reasonable principles different than described in this invention. For example, the elastic members 35 and 36 can be coupled to the L-shaped sling members 4 and 5 respectively in the manner described in the prior art (for instance, as shown in FIG. 1). In the same manner, the coupling of the elastic members 35 and 36 to the pouch 43 can be provided by any other reasonable principles (e.g., see FIG. 1).

(56) The FIG. 24 illustrates the shooter's firm gripping of the nock middle member 64, surrounded by the pouch 43, by the thumb and index finger, wherein the nock projection 48 is inserted through the aperture 44 (not shown in FIG. 24) of the pouch 43 and the pouch's nock member 49 is inserted into the rear portion 46 of the arrow projectile 45. The nock middle member 64 can be also provided, for example, by the index finger and middle finger.

(57) When the vertically adjustable directional member 6 for the use of arrow-type projectiles is not installed (not screwed-in the handle insert 12), the slingshot 1 can be used for shooting of the traditional slingshot's projectiles, such as balls (not shown), spheres (not shown), rounded stones (not shown) and other alike slingshot's traditional projectiles (not shown).

(58) The gasket 73, for instance such as rubber gasket, etc., can be installed between handle 2 and subhandle 3 (FIG. 13) to eliminate free (unlimited and independent) pivotability of the subhandle 3 with respect to the grabbed position of the handle 2, thereby, making the pivotability of the arm rest (not shown) on the forearm less loosen, because the subhandle 3 with the installed first 22 and second 23 arms of the arm rest (not shown) respectively in the first 20 and second 21 openings of subhandle 3 would be less rotatable due to the gasket 73. For such purpose, the fine thread (not shown) in addition to the gasket 73 can be used too. The handle 2 can be also manufactured in compliance with the molding procedures, and can meet all wrist ergonomic features [e.g., grooves for fingers (not shown), etc.] for slingshot operator's convenience.

(59) The small feathers (not shown) or the thin silk threads (not shown) can be used at the rear portion 46 of the arrow projectile 45.

(60) With respect to the description of this invention, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, configurations, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
