Description

Technical Field

[0001] This invention relates to a gun-type slingshot, specifically a device for launching steel balls and arrows. Background Technology

[0002] A similar device to this invention is the pistol slingshot. Current pistol slingshots typically use a traditional Y-shaped or U-shaped slingshot head, resulting in a large overall size and a long barrel. Because traditional slingshot heads can only have rubber bands attached to two ends, the number of rubber bands that can be installed is limited, making it difficult to further improve the slingshot's power and range. In traditional slingshot heads, the force on the pouch comes from two tension forces generated by the stretching of the rubber bands at both ends. Deviations in the magnitude and angle of these two tension forces, as well as deviations in the position of the projectile within the pouch, can easily affect shooting accuracy. Furthermore, because traditional slingshot heads cannot be fitted with a mechanical sight, it is difficult to adopt a three-point aligned mechanical aiming system consisting of a front sight, rear sight, and aiming point. Summary of the Invention

[0003] The purpose of this invention is to provide a device for launching steel balls and shooting arrows to solve the above-mentioned technical problems; the use of a circular bow head increases the number of rubber bands that can be installed, thereby improving the power and range of the slingshot; the use of a sabot and a firing device with a sabot limiting module improves shooting accuracy; the front sight on the bow head, the rear sight at the end of the barrel, and the aiming point together can form a three-point aligned mechanical aiming system.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A device for launching steel balls and arrows includes a sling, a firing device, a gun barrel, a bow, a rubber band, a sight, and a grip. The bow is mounted on the front end of the gun barrel, the sight is mounted on the rear end of the gun barrel, one end of the rubber band is mounted on the bow, and the other end of the rubber band is mounted on the sling. The sling is hooked onto the firing device and locked in place. The position and direction of movement of the sling are precisely constrained by a sling limiting module. The centerlines of the bow, the sling, and the sling limiting module coincide and are parallel to the centerline of the gun barrel.

[0005] The front sight on the bow head, the rear sight at the end of the barrel, and the aiming point together form a three-point aligned mechanical aiming system. The rear sight consists of a frame, a slider, and a positioning spring. The frame has markings, and the slider can move up and down. Different markings correspond to different aiming distances. Aiming systems such as laser sights, optical sights, and holographic sights can also be used.

[0006] The circular bow gate refers to a set of rubber bands installed on the bow gate, which are evenly and symmetrically distributed around the bow gate and present a circular distribution structure. It does not refer to the physical shape of the outer and inner circles of the bow gate. The physical shape of the outer and inner circles of the bow gate can be various, including but not limited to closed circles, notched circles, and polygons, as long as the rubber bands connected to the bow gate are evenly and symmetrically distributed in a circular structure; the bow head material can be one of metal, plastic, or wood.

[0007] In the aforementioned device for launching steel balls and arrows, the force on the sabot comes from the tension of numerous rubber bands distributed 360 degrees around the circular bow, making the force on the sabot and the projectile installed inside the sabot more uniform and symmetrical. In contrast, with traditional bow heads using Y-shaped or U-shaped structures, the force on the pouch comes from two tensions generated by the stretching of the rubber bands at both ends. Deviations in the magnitude and angle of these two tensions, as well as deviations in the position of the projectile within the pouch, will affect the accuracy of the shot.

[0008] The gun barrel serves as a support for the device that ejects steel balls and shoots arrows, and is used to install various components. From the front end to the rear end of the gun barrel, the bow head, firing device, sight, and grip are installed in sequence. The gun barrel can be one of a single barrel, double barrel, two-section telescopic tube, or three-section telescopic tube, and the gun barrel material can be one of metal, plastic, or wood.

[0009] The sabot includes a projectile container, a magnet, a sabot body, and an O-ring. The projectile container is conical and used to hold the projectile. The magnet is installed at the bottom of the sabot to attract and hold the projectile. The sabot body is cylindrical and has a set of rubber band positioning holes, which are evenly and symmetrically distributed along the axial direction, presenting a circular distribution structure on the cross-section of the sabot body. Using a sabot to position and launch projectiles provides better stability and accuracy than using a rubber pouch. The O-ring is made of nylon rope. The sabot is made of a lightweight, self-lubricating, tough, and strong material.

[0010] Analysis of the impact of the magnet's attraction to the projectile on launch. When launching a projectile, the attraction of the magnet must first be overcome before it can be launched. The following example demonstrates the feasibility of this design: For instance, using a 3060 round rubber band (inner diameter 3mm, outer diameter 6mm, single-strand tension approximately 6kg), a slingshot requires at least two rubber bands, resulting in a tension of 12kg. A 10mm diameter steel ball weighs approximately 4.11 grams. Using a magnet with a 12g attraction force, the attraction force accounts for approximately 12g / 12000g = 0.1%. In this device, the number of rubber bands is typically four or more, further reducing the attraction force percentage. Therefore, the projectile's launching force generated by the rubber band tension is far greater than the magnet's attraction force, and its impact on launch is negligible.

[0011] The elastic band is connected and installed on the spring by nylon thread. All the nylon threads are connected by an O-ring. When the elastic band is stretched through the O-ring, the tension of the elastic band is applied to the O-ring through the nylon thread, and the spring does not directly bear the tension of the elastic band.

[0012] The rubber band can be either a flat rubber band or a round rubber band. There are various ways to install the rubber band, and you can refer to various installation methods of traditional slingshots. Among them, the ball-clamping installation method is a relatively common and simple installation method. The ball-clamping installation method requires that the hole for installing the rubber band has a certain taper, so that the ball is pulled tighter and tighter by the rubber band in the taper hole, clamping the rubber band so that it will not be pulled off when the rubber band is stretched. The rubber band installation hole on the bow head and the rubber band positioning hole on the slingshot have a one-to-one correspondence and symmetry.

[0013] The firing device is designed based on the principles of bow and arrow breechblocks and crossbow firing devices. It includes a sabot limiting module, a trigger, a sight tooth module, a lever, a spring, and a pivot pin. An O-ring is attached to the sight tooth module, and a protrusion on the lever locks the sight tooth module in place. When the trigger is pulled, the bend of the trigger continuously presses down on the lever until the sight tooth module is unlocked, releasing the O-ring and launching the projectile. Using a finger to pull the sight tooth module backward resets it, and the spring force causes the protrusion on the lever to lock the sight tooth module again. The sabot limiting module is a hollow cylinder, restricting the sabot's movement within the cylinder. The clearance between the sabot and the cylinder precisely constrains the sabot's position and direction of movement, ensuring that the center lines of the bow head, sabot, and sabot limiting module coincide and are parallel to the center line of the gun barrel.

[0014] The projectile has magnetic adsorption properties and can be attracted by a magnet; it is made of either steel balls or iron balls.

[0015] In the above technical solution, by replacing the sling with an arrow rest, replacing the sling with an arrow, and installing a brush arrow rest on the bow head, a device for ejecting steel balls becomes a device that can be used for shooting arrows.

[0016] The beneficial effects of this invention are: it provides a powerful, long-range, and highly accurate equipment for launching steel balls and arrows.

[0017] This invention is mainly used for slingshot and archery activities in sports shooting competitions, outdoor sports, and leisure activities. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, and the technical solutions in the embodiments of the present invention will be clearly and completely described.

[0033] Example 1:

[0034] like Figure 1As shown, a device for launching steel balls and shooting arrows includes a sling (1), a firing device (3), a gun barrel (6), a bow head (7), a rubber band (8), a sight (4), and a grip (9). The bow head (7) is installed at the front end of the gun barrel (6), the sight (4) is installed at the rear end of the gun barrel (6), one end of the rubber band (8) is installed on the bow head (7), and the other end of the rubber band (8) is installed on the sling (1). The projectile (18) is installed inside the sling (1). The sling (1) is hooked to the firing device (3) and locked by an O-ring (13). The position and direction of movement of the sling (1) are precisely constrained by the sling limiting module (53). The center lines of the bow head (7), the sling (1), and the sling limiting module (53) coincide and are parallel to the center line of the gun barrel (6).

[0035] like Figure 1 As shown, the front sight (5) on the bow head (7), the rear sight (4) at the end of the barrel (6), and the aiming point together form a three-point aligned mechanical aiming system.

[0036] The material, thickness, size, and number of rubber band mounting holes (16) of the bow head (7) are determined according to the target requirements for power and range. The material used to make the bow head (7) is one of metal, plastic, or wood. In this example, a stainless steel bow head with a thickness of 8 mm, an inner diameter of 60 mm, and an outer diameter of 80 mm is used. When the ball-mounting method is used, the rubber band mounting holes (16) have a slight taper.

[0037] like Figure 7 As shown, a circular archway has an arch head (7) with rubber band mounting holes (16). The rubber band mounting holes (16) are evenly and symmetrically distributed around the circular archway, forming a circular distribution structure. One end of the rubber band (8) is installed and fixed in the rubber band mounting hole (16). When the rubber band (8) is installed using a ball clamping method, the rubber band mounting hole (16) has a slight taper, so that the ball clamps the rubber band (8) tightly and prevents it from being pulled out when stretched. The number of rubber bands (8) that can be installed is less than or equal to the number of rubber band mounting holes (16). In this example, 16 rubber band mounting holes (16) are used. The number of rubber bands (8) that can be installed includes 16, 12, 8, 4 or 2. In this embodiment, the number of rubber bands installed is 8.

[0038] The rubber band (8) is either a flat rubber band or a round rubber band; in this embodiment, a round rubber band is used, and a ball-clamping installation method is adopted. The ball-clamping installation method requires that the rubber band installation hole (16) has a slight taper (in this embodiment, the outer hole diameter is 5.2mm and the inner hole diameter is 4.2mm, and the taper is about 1mm), so that the ball is pulled tighter and tighter by the rubber band (8) in the round hole with the taper, and the rubber band (8) is clamped so that it will not be pulled off when stretched.

[0039] The method for installing the ball clamp on the round rubber band is as follows: use a small steel ball as a ball clamp, insert it into one end of the round rubber band, pinch both ends of the round rubber band and stretch the round rubber band to make the round rubber band thinner and longer, so that it can enter the rubber band installation hole (8) through the channel (9), and then tighten the ball clamp to fix the round rubber band in the rubber band installation hole (8).

[0040] The gun barrel (6) serves as a support for the device that ejects steel balls and shoots arrows, and is used to install various components. From the front end to the rear end of the gun barrel (6), the bow head (7), the firing device (3), the sight (4), and the grip (9) are installed in sequence. The gun barrel (6) can be made of one of the following: single barrel, double barrel, two-section telescopic tube, or three-section telescopic tube. In this embodiment, a single barrel is used. The gun barrel (6) is made of one of the following: metal, plastic, or wood. In this embodiment, a stainless steel tube is used to make the gun barrel (6).

[0041] like Figure 3 and Figure 4 As shown, a sabot (1) includes a projectile container (10), a magnet (11), a sabot body (12), and an O-ring (13). The projectile container (10) is conical and is used to hold the projectile (18). The magnet (11) is installed at the bottom of the sabot (1) and is used to attract the projectile (18). The sabot body (12) is cylindrical and has a set of rubber band positioning holes (15) that are evenly and symmetrically distributed in a circular shape along the axial direction. The sabot (1) is made of a lightweight, self-lubricating, tough, and certain strength material. In this example, nylon material is used to make the sabot (1), and nylon rope is used to make the O-ring (13).

[0042] like Figure 5 As shown, the installation and use of the sabot (1) are as follows: one end of the rubber band (8) is connected to the rubber band positioning hole (15) of the sabot (1) through the nylon line (14), and the nylon line (14) is tied together with a soft line at the groove (19), and then an O-ring (13) is threaded through it. When the rubber band (8) is stretched through the O-ring (13), the tension of the rubber band (8) is applied to the O-ring (13) through the nylon line (14), and the sabot (1) does not directly bear the tension of the rubber band (8); the rubber band positioning hole (15) on the sabot (1) and the rubber band mounting hole (16) on the bow head have a one-to-one correspondence and symmetrical relationship. In this embodiment, there are 8 rubber band positioning holes (15).

[0043] The projectile (18) is made of a metal that has magnetic adsorption properties and can be attracted by a magnet (11). It is either a steel ball or an iron ball. In this embodiment, a steel ball is used.

[0044] like Figure 6As shown, the firing device (3) is made based on the principles of bow and arrow string catch and crossbow firing device. The firing device includes a sling limit module (53), trigger (30), sight module (31), lever (32), spring (33), and pivot pin (34). The O-ring (13) is attached to the sight module (31). The lever (32) locks the sight module (31). When the trigger (30) is pulled, the lever (32) is pressed down until the sight module (31) is unlocked, releasing the O-ring (13) and launching the projectile (18). The sight module (31) is pulled back by hand. The tooth peak is adjusted until the sight tooth module (31) is straightened and reset. The lever (32) locks the sight tooth module (31) again under the force of the spring (33). The cartridge (1) is pushed into the cartridge limit module (53), and the O-ring (13) is hooked on the sight tooth module (31). The cartridge (1) is restricted to move back and forth in the cylinder. The fit gap between the cartridge (1) and the cylinder precisely constrains the position and direction of movement of the cartridge (1), ensuring that the center lines of the bow head (7), the cartridge (1), and the cartridge limit module (53) coincide and are parallel to the center line of the gun barrel (6).

[0045] like Figure 8 As shown, the sight (4) is composed of a door frame (50), a slider (51) and a positioning spring (52). The door frame (50) has a scale, and the slider (51) can move up and down. Different scales correspond to different aiming distances.

[0046] After completing the above steps, as follows Figure 1 As shown, use your fingers to straighten the sight module (31) and reset it. The sight module (31) is locked by the protrusion of the lever (32). Then, pinch the cartridge case (1) or use a tool to hook the O-ring (13) and pull the rubber band (8) backward to lock the O-ring (13) onto the firing device (3). Put the projectile (18) into the projectile container (10) and it will be attracted by the magnet (11) so that the projectile (18) is in the ready-to-fire state. Using the three-point mechanical aiming method, pull the trigger (30) to launch the projectile (18).

[0047] Example 2:

[0048] like Figure 9 As shown, a device for launching steel balls and shooting arrows includes an arrowstock (40), a brush arrow rest (46), a triggering device (3), a sight (4), a gun barrel (6), a bow head (7), a rubber band (8), and a grip (9). Based on the first embodiment, the arrowstock (1) in the first embodiment is replaced with an arrowstock (40), the projectile (18) is replaced with an arrow (45), and a brush arrow rest (46) is installed on the bow head (7), thus becoming a device that can be used to shoot arrows (45).

[0049] like Figure 2 The diagram shows the structure of the brush arrow holder (46). The brush arrow holder (46) adopts a brush arrow holder for a pocket slingshot that is already available on the market. The brush arrow holder (46) includes a brush (60), a brush bracket (61), and a brush mounting hole (62).

[0050] like Figure 10 The diagram shows the assembly of the brush arrow holder (46). The brush arrow holder (46) is mounted on the bow head (7) and fixed to the bow head (7) with screws. The arrow (45) head rests on the center hole of the brush arrow holder (46), and the arrow (45) tail is fastened into the bowstring (42) of the arrow stock (40). In this example, the thickness of the brush arrow holder (46) is 8 mm, the outer diameter is 60 mm, and the inner diameter is 52 mm.

[0051] like Figure 11 and Figure 12 As shown, the arrowstock (40) includes a bracket (41), a retaining string (42), and an O-ring (13). The bracket (41) is a hollow cylinder with a set of rubber band positioning holes (15) that are evenly and symmetrically distributed along the axis of the cylinder, presenting a circular distribution structure on the cross-section of the bracket (41). The arrowstock (1) is made of a lightweight, self-lubricating, tough, and strong material.

[0052] like Figure 13 As shown, the arrowstock (40) is installed and used as follows: one end of the rubber band (8) is connected to the rubber band positioning hole (15) of the arrowstock (40) through the nylon line (14) and fixed with the soft line (19). The nylon line (14) is connected together and then an O-ring (13) is threaded through it. When the rubber band (8) is stretched through the O-ring (13), the tension of the rubber band (8) is applied to the O-ring (13) through the nylon line (14). The arrowstock (40) does not directly bear the tension of the rubber band (8). The rubber band positioning hole (15) and the rubber band mounting hole (16) of the bow head have a one-to-one correspondence and symmetrical relationship. In this embodiment, there are 8 rubber band positioning holes (15).

[0053] After completing the above steps, as follows Figure 9 As shown, use your fingers to straighten the sighting module (31) and reset it. The sighting module (31) is locked by the protrusion of the lever (32). Place the arrow (45) head on the center hole of the brush arrow holder (46), and fasten the arrow (45) tail into the string (42) of the arrowstock (40). Then, pinch the arrowstock (40) with your hand or use a tool to hook the O-ring (13) and pull the rubber band (8) backward to lock the O-ring (13) onto the firing device (3), so that the arrow (45) is in the ready-to-fire state. Using the three-point mechanical aiming method, pull the trigger (30) to launch the arrow (45).

[0054] Finally, it should be noted that the embodiments described above are only some embodiments of the present invention, and not all embodiments; based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
