Description

Technical Field

[0001] This utility model relates to a U-shaped bowstring placement device, specifically for use in the field of crossbows and arrows. Its main purpose is to provide users with a way to avoid interference with or contact with the bowstring after pulling it with the bowstring, thus ensuring a secure placement and facilitating the stability of subsequent bowstring shooting and operation. Background Technology

[0002] Bowstring tension in archery is generally very high, which allows the arrow to be shot to a distant target after the bowstring is released. However, because of the high tension, users often have to exert a great deal of force when drawing the bowstring. Due to insufficient force or carelessness in releasing the bow, the bowstring may slip and injure the user, causing not only cuts and lacerations but also potentially irreversible damage, especially common with crossbow-type bows.

[0003] Therefore, based on the aforementioned dangerous issues, industry players in this field have developed a device that can replace manual bowstring drawing—a string drawer or stringer, as seen in patent publication number M641344 "Crossbow String Drawing Structure." Its main function is to use a string drawing device to control the string drawing unit, allowing the unit to pull the bowstring to draw the string. After completion, the string drawing unit is removed from the crossbow body and inserted into a groove between the bow and the stock (see Figure 9 of the patent), avoiding interference with bowstring firing and arrow accuracy. However, these players have overlooked... One issue is that when the drawstring unit is being withdrawn and deployed, the bowstring is in a taut, cocked state. Therefore, as the drawstring unit is being withdrawn and passes over the area where the sight can be installed, the bowstring is very likely to come into contact with it, causing the bowstring to shift or become loose. This will affect the stability of the arrow after it is fired. In addition to the drawstring unit's deployment and retraction position, there are other locations, such as those attached to the side of the stock or retracted at the butt end of the stock. Regardless of the deployment or retraction method, the bowstring is very easy to come into contact with. Utility Model Content

[0004] The purpose of this invention is to prevent the user from touching the bowstring during the process of releasing the drawstring after stringing, and to enable quick placement of the bow and arrow, preventing the bowstring from being touched and thus coming off the string. Furthermore, it eliminates the need for time and physical effort in operation, thus improving upon the shortcomings of the prior art, such as the bow and arrow touching the bowstring during the operation of the drawstring unit for placement, which could lead to bowstring coming off the string or even injuring the user. Therefore, the creator of this invention strives to achieve the aforementioned objectives and effects. This utility model provides a U-shaped drawstring holder placement device, primarily offering a place to hold a drawstring. It includes: a bow body comprising a bow shaft, a stock located at both ends of the bow shaft, a bowstring assembly, and a trigger assembly located at the lower end of the bow shaft. The drawstring is mounted on the upper part of the bow shaft and movably hooks onto a bowstring of the bowstring assembly; a main control box, partially installed inside the end of the bow shaft connected to the stock, and mechanically linked to the trigger assembly, with another portion protruding from the upper surface of the bow shaft; and a string control assembly installed on the side of the stock and connected to the drawstring. The string control assembly drives the drawstring towards... The bowstring moves toward the stock, causing it to move closer to the main control box; and a mounting bracket is installed on the protruding part of the main control box, forming a mounting slot between the mounting bracket and the main control box. The mounting slot has a front opening and two side openings, which are connected to the front opening. The drawstring pulls the bowstring toward the main control box, and after the main control box secures the bowstring in the strung state, the drawstring releases its hook from the bowstring and moves upward to avoid the bowstring and inserts into the mounting slot. The drawstring enters through the front opening and slides into the two side openings, so that part of the drawstring is mounted on the mounting slot, while the other part of the drawstring is located at the rear end of the strung bowstring.

[0005] A further technical feature of this utility model is that the mounting bracket is further recessed to form a mating groove corresponding to the protruding part of the main control box. The protruding part of the main control box is inserted into the mating groove, and at least one screw is inserted from the upper end of the mounting bracket and locked to the main control box.

[0006] A further technical feature of this utility model is that the main control box further includes two shell parts that fit together, and the two shell parts each have a mounting protrusion, an upper chord section, an upper rib and a lower shell part located at both ends of the upper chord section, and a positioning section is formed between the upper ribs of the two shell parts, the positioning section connecting the frame slot and each upper chord section.

[0007] A further technical feature of this utility model is that the stringer further includes a main buckle and two side arm ribs located on both sides of the main buckle. One end of each side arm rib is connected to both sides of the main buckle, and the other end of each side arm rib extends in the opposite direction to the main buckle and is respectively equipped with a wheel axle. A string of the string control group passes through the end of each side arm rib with a wheel axle, and the string abuts against the outer surface of each wheel axle.

[0008] A further technical feature of this utility model is that the bottom surface of the main buckle of the bowstring is further provided with a string-hooking part and a positioning protrusion. The string-hooking part hooks the bowstring and pulls it toward each upper string channel. The positioning protrusion is used after the bowstring is unhooked from the bowstring, the bowstring is placed into the frame groove and slides into the positioning channel, thereby limiting the shaking of the bowstring in the frame groove.

[0009] A further technical feature of this utility model is that an elastic positioning group is further installed in the connecting groove. After the stringer is placed into the frame groove, the elastic positioning group elastically abuts against the stringer to prevent it from falling off.

[0010] A further technical feature of this utility model is that the elastic positioning group further includes an elastic positioning piece and a screw. One end of the elastic positioning piece is inserted into the connecting groove and locked in place by the screw, while the other end of the elastic positioning piece is elastically bent downwards. After the stringer is placed into the frame slot, the bent end of the elastic positioning piece elastically abuts against the stringer.

[0011] A further technical feature of this utility model is that the elastic positioning assembly further includes a mounting block, a spring, and a positioning bead. The mounting block is movably installed in the connecting groove and has an assembly hole. The spring is installed in the assembly hole, and the positioning bead is embedded in the assembly hole and is elastically pushed by the spring, so that part of the positioning bead protrudes from the opening of the assembly hole. The opening diameter of the assembly hole is smaller than the circular diameter of the positioning bead. The part of the positioning bead protruding from the assembly hole is pushed against the stringer by the elastic push of the spring. Attached Figure Description

[0061] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0062] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0063] The following is a reference to the appendix. Figure 1 To be continued Figure 10This invention describes a U-shaped drawstring holder placement device, which mainly provides a drawstring holder 10 for placement. It includes: a bow body 1, comprising a bow shaft 11, a stock 12 located at both ends of the bow shaft 11, a bowstring assembly 13, and a trigger assembly 14 located at the lower end of the bow shaft 11. The drawstring holder 10 is mounted on the upper end of the bow shaft 11 and movably hooks onto a bowstring 131 of the bowstring assembly 13, and movably pulls the bowstring 131 to wind the bow; a main control box 2, partially installed within the bow shaft 11. The bow 11 is connected to the interior of one end of the stock 12, and the main control box 2 is mechanically linked to the trigger assembly 14. Another part of the main control box 2 protrudes from the upper surface of the bow 11. The main control box 2 is mainly used to restrict and release the bowstring 131 from being in the cocked or released firing state. A string control assembly 3 is mounted on the side of the stock 12 and connected to the drawstring 10. The string control assembly 3 drives the drawstring 10 to move towards the stock 12, thereby driving the bowstring 131 towards the stock 12. The main control box 2 is located close to the main control box 2, and its operation is mainly controlled by wires; and a mounting bracket 4 is installed on the protruding part of the main control box 2, and a mounting slot 41 is formed between the mounting bracket 4 and the main control box 2. The mounting slot 41 has a front opening 411 and two side openings 412, and the two side openings 412 are connected to the front opening 411. In addition, the upper part of the mounting slot 41 is mainly used to provide mounting for other accessories, such as sights (not shown); wherein, the drawbar 10 pulls The bowstring 131 moves toward the main control box 2, and after the bowstring 131 is fixed in the strung state by the main control box 2, the drawstring 10 releases its hook from the bowstring 131 and moves upward to avoid the bowstring 131 and inserts into the mounting slot 41. The drawstring 10 enters through the front opening 411 and slides into the two side openings 412, so that part of the drawstring 10 is mounted on the mounting slot 41, while the other part of the drawstring 10 will be located at the rear end of the strung bowstring 131.

[0064] Based on the above definition of the main technical aspects of this utility model, during the stringing operation, the user first uses the string control assembly 3 to drive the bowstring puller 10 to pull the bowstring 131 towards the main control box 2. Once the bowstring 131 is pulled to its position, the main control box 2 will first restrict the bowstring 131 to a taut, strung state. At this time, the bowstring 131 is in an arc shape. After confirming that the bowstring 131 is restricted by the main control box 2, the bowstring puller 10 can be released from the hook of the bowstring 131, and the bowstring puller 10 can be slowly pulled away from the main control box 2. After the bowstring puller 10 is completely pulled away, it can be moved a short distance upwards to the position of the mounting slot 41. This process will not interfere with or touch the already strung bowstring 131, unlike the prior art where placement requires moving to a greater distance and flipping over the top, which could easily result in accidental contact with the bowstring. Therefore, this utility model adopts... The drawstring 10 is placed at a relatively close distance. Once the drawstring 10 is aligned with the mounting slot 41, it is directly inserted into the mounting slot 41. This results in part of the drawstring 10 being placed in the mounting slot 41, while the other part is positioned behind the already strung bowstring 131. Therefore, this method of providing the drawstring 10 not only avoids the possibility of contact with the bowstring 131, but also eliminates the need to expend effort to move the drawstring 10 to the furthest point and flip it over the mounting bracket. The drawstring 10 can be quickly placed through simple operation, allowing the user to shoot. Furthermore, because the mounting slot 41 is designed to be close to the bowstring 131, the drawstring 10 can be moved to the mounting slot 41 for stable placement once the hook to the bowstring 131 is released, without affecting the bowstring 131, thus allowing the user to shoot stably.

[0065] Based on the above description, the other technical features of this utility model will be further detailed below. First, please refer to Figures 2 to 5. In order to ensure that the drawbar 10 can be securely placed in the mounting slot 41, the design of the mounting bracket 4 and the main control box 2 is crucial. Therefore, the structural features of the mounting bracket 4 will be described first. The mounting bracket 4 is elongated to provide a mounting surface for the sight. Furthermore, the mounting bracket 4 is further recessed to form a mating groove 42 corresponding to the protruding portion of the main control box 2. The protruding portion of the main control box 2 is inserted into the mating groove 42, and at least one screw 5 passes through the upper end of the mounting bracket 4. The main control box 2 is inserted and locked into it; the main control box 2 further includes two shells 21 that fit together, and each shell has a mounting protrusion 211, an upper chord groove 212, and an upper rib 213 and a lower shell 214 located at both ends of the upper chord groove 212. After the two shells 21 fit together, their interiors have space for the installation of related instruments (such as safety instruments, hooking instruments, etc.). A positioning groove 215 is formed between the upper ribs of the two shells 21, and the positioning groove 215 connects the rack slot 41 and each upper chord groove 212.

[0066] Continuing from the previous description, and knowing the structural features of the mounting bracket 4 and the main control box 2, the structural part of the bowstring 10 will be described further. To ensure that the bowstring 10 can be reliably and securely placed within the mounting slot 41, the bowstring 10 further includes a main latch 101 and two side arm ribs 102 located on both sides of the main latch 101 (see Figure 14). The bowstring 10 is U-shaped overall. One end of each side arm rib 102 is connected to both sides of the main latch 101, while the other end of each side arm rib 102 extends in the opposite direction to the main latch 101 and is respectively fitted with a wheel axle 103. A drawwire 31 of the control assembly 3 passes through the end of each side arm rib 102 with a wheel axle 103, and the drawwire 31 abuts against the outer surface of each wheel axle 103. Therefore, based on the above description, using… The user uses the control assembly 3 (primarily shown by rotating the handle) to move the drawstring 31 to the bowstring 10. The bowstring 10 moves on the bow body 11 and pulls the bowstring 131 towards the upper stringing channel 212 and into it. Then, the main control box 2 uses the string hooking device to hook and position the bowstring 131 in the upper stringing state. At this time, the user can pull the bowstring 10 out of the upper stringing channel 212 and move it to the position of the frame slot 41 for placement. The main hook part 101 of the bowstring 10 is inserted into the frame slot 41, and the two side arm ribs 102 are positioned behind the bowstring 131 in the upper stringing state. In the above description, the movement of the bowstring 10 will not touch or interfere with the upper stringing of the bowstring 131, avoiding the bowstring 131 from coming off and ensuring the user's safety during operation.

[0067] In addition to the above-described main technical features of this utility model, as shown in Figures 5, 6, and 14, the function of the bowstring 10 is to allow the user to pull the bowstring 131 without expending excessive force. Regarding the placement of the bowstring 10, in order to securely insert the bowstring 10 into the mounting slot 41, the bottom surface of the main buckle portion 101 of the bowstring 10 is further provided with a string-hooking portion 104 and a positioning protrusion 105. The string-hooking portion 104 is a hook. The bowstring 131 is pulled toward each upper stringing groove 212. The positioning protrusion 105 is used after the drawstring 10 is released from the hook of the bowstring 131. The drawstring 10 is placed into the frame slot 41 and slides into the positioning groove 215, thereby limiting the swaying of the drawstring 10 in the frame slot 41. This ensures that the drawstring 10 will not affect the firing or ejection of the bowstring 131 during shooting, as shown in Figure 9.

[0068] Finally, to ensure the stable placement of the drawstring 10 relative to the mounting slot 41, and to prevent the drawstring 10 from falling off during firing, an elastic positioning assembly 6 is further installed in the mounting slot 42. After the drawstring 10 is placed into the mounting slot 41, the elastic positioning assembly 6 elastically abuts against the drawstring 10 to prevent it from falling off. The elastic positioning assembly 6 has two embodiments. First, as shown in Figures 1 to 10 and 14, the elastic positioning assembly 6 further includes an elastic positioning piece 61 and a screw 62. One end of the elastic positioning piece 61 is inserted into the mounting slot 42 and locked in place by the screw 62. The other end of the elastic positioning piece 61 is elastically bent towards the positioning channel 215, and after the drawstring 10 is placed into the mounting slot 41, the bent end of the elastic positioning piece 61 elastically abuts against the main buckle portion 101 of the drawstring 10. Furthermore... Referring to Figures 11 to 14, the elastic positioning assembly 6 further includes a mounting block 63, a spring 64, and a positioning bead 65. The mounting block 63 is movably mounted in the connecting groove 42 and has an assembly hole 631. The spring 64 is installed in the assembly hole 631, and the positioning bead 65 is embedded in the assembly hole 631 and is elastically pushed by the spring 64, so that part of the positioning bead 65 protrudes from the opening of the assembly hole 631. The opening diameter of the assembly hole 631 is smaller than the circular diameter of the positioning bead 65. The part of the positioning bead 65 protruding from the assembly hole 631 is pushed against the drawstring 10 by the elastic push of the spring 64. Through the above two elastic positioning assemblies 6, combined with the matching of the positioning protrusion 105 and the positioning channel 215, the drawstring 10 can be stably mounted in the mounting groove 41 during shooting and is not easy to fall off, providing the user with stable shooting operation.

[0069] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
