Description

Technical Field

[0001] The present invention relates to the technical field of bow and arrow sights, and in particular to an angle indicating device and a fine-adjustment bow and arrow sight. Background Art

[0002] Archery has a long history and was originally used for hunting and war. The first archers were hunters who used bows and arrows to kill animals to survive. Later, bows and arrows became terrible weapons in war. At present, it has mainly developed into a kind of archery sport, namely archery, which refers to the sport of shooting arrows with the help of the elastic force of the bow and competing for accuracy within a certain distance. It is also called archery.

[0003] Bow and arrow is a well-known tool, widely used in fitness, competition, hunting, actual combat and other fields. Ordinary bow and arrow includes a bow body with a string and an arrow. When using it, the tail end of the arrow is placed on the string, one hand holds the bow body, and the other hand pulls the string and the arrow on the string backwards. At the same time, the arrow is aimed at the target object, and the string is quickly released. Under the action of the rebound force of the string, the arrow is quickly shot towards the target.

[0004] Since traditional bows and arrows do not use any auxiliary aiming equipment, they can only be aimed directly by the naked eye of the user, and the accuracy of the arrows shot depends largely on the user's experience and judgment. For novices, it may be difficult to guarantee accuracy.

[0005] Later, a bow and arrow that can improve shooting accuracy also appeared. Its structure includes a bow body and an arrow, wherein the bow body is equipped with a sight. The sight includes a sight window, and a sight is arranged in the sight window. There is also an observation hole installed at the rear of the sight. The user observes the target point of the sight in the distance through the observation hole, and then aims at the target object, and then releases the arrow, which can improve accuracy.

[0006] However, the position of the sight in the above structure relative to the bow body is fixed, and different users may have different usage habits. In particular, when shooting at targets at different distances, the sight also needs to be adjusted accordingly. However, the fixed-position sight is not user-friendly and inconvenient to use.

[0007] For example, a Chinese patent document with publication number CN110906792A discloses an aiming device for archery, including an aiming frame, a rotating frame rotatably connected to the aiming frame, four sight mechanisms are arranged inside the rotating frame, and the opposite ends of the four sight mechanisms are evenly distributed on the inner wall of the rotating frame, a fixed frame is fixedly installed on the right side of the aiming frame, a fixed rod is fixedly installed on the fixed frame, and a transverse support block is arranged on the front side of the fixed frame.

[0008] However, the above solution is difficult to adjust the sight vertically, and it also involves the problem of the shooting angle of the bow and arrow when shooting at a target at a long distance.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 10In an embodiment of the present invention, an angle indicating device includes a first pointer, a first track member 20 and a first conversion member, wherein one end of the first pointer is rotatably connected to a stationary member of a sight, and the other end thereof forms a free end; the first track member 20 is fixedly connected to the stationary member of the sight, and the first conversion member can move along the track of the first track member 20; one end of the first conversion member is transmission-connected to the first pointer, and the other end thereof is transmission-connected to a movable member of the sight, and the movable member of the sight moves a certain distance relative to the stationary member, thereby driving the first conversion member to move synchronously along the track of the first track member 20, and driving the first pointer to rotate a certain angle.

[0030] Specifically, when using a bow and arrow to shoot and aim, the target, the sight of the scope and the user's line of sight are on the same straight line, which is the aiming line. When shooting at a target at a longer distance, it is usually necessary to shoot at an elevation angle, that is, the arrow may be shot from above the aiming line, forming a certain angle with the aiming line, i.e., the arrow's elevation angle. In this way, the arrow can hit a target at a longer distance by using the parabolic trajectory after being shot.

[0031] In order to clearly know the elevation angle of the arrow when preparing for shooting, an angle indicator device can be set on the sight. When aiming at a certain target, the aiming line is also determined. At this time, adjusting the sight is equivalent to adjusting the position of the bow and arrow relative to the aiming line. For example, adjusting the sight downward on the bow and arrow is equivalent to adjusting the bow and arrow above the aiming line relative to the aiming line. Therefore, this feature can be used to convert the vertical movement of the sight into a corresponding angle indication, so that the shooting elevation angle can be prompted accordingly, making it easier for users to adjust, view and use the elevation angle of the bow and arrow, improving the user experience, and also improving the user's shooting accuracy.

[0032] Secondly, since the sight of the bow sight is mounted on the vertical slide 60, adjusting the sight is to move the vertical slide 60 up and down, and the first driving member 40 moves synchronously with the vertical slide 60, and can drive the conversion slider 30 to move a certain distance along the arc guide rail. Since the arc guide rail has a certain curvature, when the conversion slider 30 moves along the arc guide rail, its motion trajectory also has a certain curvature, which is equivalent to the conversion slider 30 itself rotating a smaller angle.

[0033] Therefore, the conversion slider 30 that changes its own rotation angle will also drive the long pointer 10 connected thereto to rotate accordingly, so that the free end of the long pointer 10 can indicate the corresponding rotation angle, that is, the elevation angle relative to the aiming line when the bow shoots the arrow. After knowing the elevation angle of the bow, the corresponding estimated calculation can be performed according to the distance of the target, the performance parameters of the bow and arrow, etc., so as to improve the accuracy of shooting at a distant target and enhance the shooting experience of the user.

[0034] In the first embodiment of the present invention, Figures 1 to 4 As shown, preferably, the first pointer is provided with a long pointer 10, the first conversion member is provided with a conversion slider 30, the first track member 20 is provided with a track plate 22, and the track plate 22 is provided with an arc-shaped through hole 23, thereby forming an arc-shaped guide rail; the fixed member of the sight is provided with a vertical bracket 50 for installation on an external bow and arrow, and the movable member of the sight is provided with a vertical slide seat 60 for installing a front sight assembly 90; the end of the vertical bracket 50 facing the vertical slide seat 60 is provided with a vertical slide rail 52, and the vertical slide seat 60 slides The long pointer 10 is rotatably connected to the vertical slide rail 52, thereby driving the sight assembly 90 to be vertically adjusted along the vertical bracket 50; one end of the long pointer 10 is rotatably connected to the vertical bracket 50, and the other end thereof forms a free end, the track plate 22 is fixed to the vertical bracket 50, one end of the conversion slider 30 is transmission-connected to the long pointer 10, and the other end thereof is transmission-connected to the vertical slide seat 60, and the conversion slider 30 is penetrated by the arc-shaped guide rail of the track plate 22, so that the conversion slider 30 can perform an arc motion along the arc-shaped track of the arc-shaped guide rail.

[0035] Specifically, the first track member 20 is provided with an arc track, and the conversion slider 30 is also provided with a guide column 32. The guide column 32 can be passed through the arc guide rail of the track plate 22 and abut against the side wall of the arc guide rail, so that the guide column 32 can slide along the arc track, so that the conversion slider 30 can perform corresponding arc motion.

[0036] Secondly, the conversion slider 30 can also be set as an arc-shaped slider (not shown in the figure), and the curvature of the arc-shaped slider is the same as the curvature of the arc-shaped guide rail, so that the arc-shaped portion of the entire arc-shaped slider is used to penetrate the arc-shaped guide rail of the track plate 22. In order to enable the conversion slider 30 to move more smoothly along the arc-shaped guide rail, and to rotate in its own direction strictly according to the curvature of the arc-shaped guide rail, and then accurately drive the long pointer 10 to rotate a corresponding angle, it is preferred that the conversion slider 30 is set as an arc-shaped slider with a certain curvature, and the curvature of the arc-shaped slider should be equal to the curvature of the arc-shaped guide rail.

[0037] In addition, one end of the vertical bracket 50 can be mounted on the external bow and arrow through the tail bracket 51, and the other end thereof is connected to the vertical slide 60. The vertical slide 60 can slide along the vertical bracket 50, that is, the vertical slide 60 can be vertically moved relative to the vertical bracket 50 by the user performing vertical operation on the vertical slide 60. The first driving member 40 fixed to the vertical slide 60 will also move synchronously, so the synchronously moving first driving member 40 can also drive the conversion slider 30 to slide along the arc guide rail, so that the conversion slider 30 can transmit the long pointer 10, so that the long pointer 10 rotates a certain angle.

[0038] In another embodiment, a certain linear relationship may be formed between the moving distance of the vertical slide 60 and the rotation angle of the long pointer 10 .

[0039] In order to optimize the adjustment parameters of the angle indicating device for the angle, preferably, the calculation formula of the rotation angle of the long pointer 10 is: Wherein L is the moving distance of the vertical slide 60 , R is the diameter of the arc where the arc guide rail is located, and α is the rotation angle of the long pointer 10 .

[0040] Specifically, π is the circumference of a circle, and the value 3.14159 can be used here for calculation. For example, when the diameter R of the arc where the arc guide rail is located is 267 mm, the moving distance L of the vertical slide 60 along the vertical bracket 50 is 42 mm, and the rotation angle α of the long pointer 10 is rounded to 9 degrees. It can be understood that the rounding here is just for the convenience of description. In the actual use of the angle indicating device, the angle change of the long pointer 10 should be a continuous linear change, and the moving distance of the vertical slide 60 does not necessarily need to move an integer unit, but according to the user's adjustment, its moving distance is also a continuous linear change.

[0041] like Figures 1 to 3 As shown, preferably, the vertical slide 60 is also provided with a first driving member 40, one end of the first driving member 40 is fixedly connected to the vertical slide 60, and the other end thereof is transmission-connected to the conversion slider 30; the first driving member 40 slides along the vertical bracket 50 with the vertical slide 60, thereby driving the conversion slider 30 to perform an arc motion along the arc guide rail.

[0042] Specifically, a connecting rod 43 is provided between the first driving member 40 and the conversion slider 30, one end of the connecting rod 43 is transmission-connected to the first driving member 40, and the other end thereof is transmission-connected to the conversion slider 30. By providing a connecting rod 43, openings can be provided at both ends of the connecting rod 43, so that the opening at one end of the connecting rod 43 is just sleeved on the driven rod 31 of the conversion slider 30, and the opening at the other end thereof is sleeved on the active rod 42 of the first driving member 40. Therefore, when the first driving member 40 follows the vertical slide 60 to slide along the vertical bracket 50, the active rod 42 of the first driving member 40 can drive the conversion slider 30 to move in an arc along the arc guide rail through the connecting rod 43.

[0043] Secondly, since the first driving member 40 moves vertically following the vertical slide 60, and when the conversion slider 30 slides along the arc trajectory, it will produce both vertical and lateral movements. Therefore, in order to optimize the transmission connection between the first driving member 40 and the conversion slider 30, it is preferred to set a connecting rod 43 so that its two ends can rotate separately, so that it can generate corresponding driving force on the conversion slider 30.

[0044] like Figure 1 and Figure 2 As shown, preferably, the vertical bracket 50 is provided with an auxiliary bin 54 and a scale plate 55, the auxiliary bin 54 is arranged on the side wall of the vertical bracket 50, and the scale plate 55 covers the opening of the auxiliary bin 54 to form a fixed connection; one end of the long pointer 10 is rotatably connected in the auxiliary bin 54, the track pad 22 is fixed to the auxiliary bin 54, and the conversion slider 30 is movably installed in the auxiliary bin 54.

[0045] Specifically, the track pad 22, the long pointer 10, the conversion slider 30 and the connecting rod 43 can be installed in the auxiliary bin 54, and a scale plate 55 can be set at the opening of the auxiliary bin 54 to cover the auxiliary bin 54. A long opening (not shown in the figure) is provided in the side wall of the auxiliary bin 54 corresponding to the first driving member 40, so that one end of the first driving member 40 can extend into the auxiliary bin 54 and form a transmission connection with the connecting rod 43.

[0046] Secondly, the free end of the long pointer 10 is provided with an angle pointer 12, and a corresponding arc-shaped opening (not shown in the figure) can also be provided at a position of the scale plate 55 corresponding to the angle pointer 12, so that one end of the angle pointer 12 can extend into the auxiliary chamber 54 and form a fixed connection with the free end of the long pointer 10. It can be understood that an elevation scale can also be provided on the surface of the scale plate 55 at a position corresponding to the angle pointer 12, so that the angle pointer 12 moves a certain distance under the drive of the long pointer 10, thereby indicating the corresponding elevation angle.

[0047] Again, a vertical pointer 44 can also be set on the first driving member 40. The vertical pointer 44 is fixedly connected to the first driving member 40. The surface of the scale plate 55 is provided with a vertical scale corresponding to one side of the vertical pointer 44, so that when the vertical pointer 44 follows the first driving member 40 to move along the vertical bracket 50, it can indicate the corresponding vertical movement distance.

[0048] like Figure 3 and Figure 4 As shown, preferably, the conversion slider 30 is transmission-connected to one side of the long pointer 10 and is provided with a limit slot 33, and the long pointer 10 is slidingly connected to the limit slot 33, and the long side of the long pointer 10 abuts against the side wall of the limit slot 33, thereby being driven by the side wall of the limit slot 33 and then rotating to a certain angle.

[0049] Specifically, the side wall of the limit slot 33 can be used to drive the long pointer 10 to change a certain angle, thereby indicating the corresponding angle change. A limit gear 34 can also be provided on one side of the limit slot 33, and a limit rack 11 is provided on the side of the long pointer 10 corresponding to the limit gear 34. The limit rack 11 and the limit gear 34 cooperate with each other to form a meshing transmission connection. Thus, the auxiliary limit slot 33 drives the long pointer 10, so that it can change the rotation angle following the movement of the conversion slider 30.

[0050] like Figures 5 to 7 As shown, preferably, the present invention also provides a fine-tuning sight for bows and arrows, including the above-mentioned angle indicating device, and also including a vertical movement mechanism 62 installed on the vertical slide 60, a transverse movement mechanism 70 installed on the vertical movement mechanism 62, and a front sight assembly 90 installed on the transverse movement mechanism 70; the front sight assembly 90 is used to assist the user in aiming at the target, the transverse movement mechanism 70 is used to perform lateral movement adjustment on the front sight assembly 90, and the vertical movement mechanism 62 is used to perform vertical movement adjustment on the transverse movement mechanism 70 and the front sight assembly 90.

[0051] Specifically, in order to adjust the sight in multiple directions, a corresponding vertical movement mechanism 62 may be provided to adjust the sight in the vertical direction. A corresponding horizontal movement mechanism 70 may be provided to adjust the sight in the horizontal direction. The sight assembly 90 may be provided with a sight rod 91 and a sight window 92 in the prior art, one end of the sight rod 91 being fixed to the horizontal movement fastener 75, and the other end thereof being fixed to the sight window 92, and the sight window 92 is used to assist in aiming at the target.

[0053] Specifically, a locking wrench 61 is also provided at the position of the vertical slide 60 relative to the vertical slide rail 52. The locking wrench 61 is threadedly connected to the vertical slide 60 and can lock the vertical slide rail 52, so that the vertical slide 60 remains locked relative to the vertical slide rail 52, thereby improving its stability and preventing the vertical slide 60 from slipping when no operation is performed.

[0054] In addition, a steel block in existing products can be set between the clamping slider 63 and the vertical slide rail 52, and its good wear resistance and self-lubricating properties can be used to optimize the sliding connection between the two. Polyoxymethylene (POM), also known as acetal resin, polyoxymethylene, polyacetal, is a thermoplastic crystalline polymer, known as "super steel" or "steel". It can be understood that a corresponding tension adjustment mechanism in the existing technology can also be set on the clamping slider 63, so that the clamping slider 63 can be better clamped on the vertical slide rail 52.

[0055] like Figure 5 and Figure 7 As shown, preferably, the transverse movement mechanism 70 is provided with a transverse movement base 71 and a transverse movement fastener 75, one end of the transverse movement base 71 is detachably fixed to the vertical slide 60, and the other end thereof is provided with a transverse movement screw 73, the transverse movement screw 73 is rotatably connected to the transverse movement base 71, and is installed with a second knob 74; one end of the transverse movement fastener 75 is detachably fixed to the sight assembly 90, and the other end thereof is slidably connected to the transverse movement base 71, and forms a threaded transmission connection with the transverse movement screw 73, so that rotating the second knob 74 can drive the transverse movement fastener 75 to move laterally along the transverse movement base 71.

[0056] Specifically, the traverse base 71 is further provided with a knob clamp 72 (not shown in the figure), which can be inserted into the clamp hole of the second knob 74, thereby locking the second knob 74 and improving its stability. Similarly, a corresponding tension adjustment mechanism in the prior art can also be provided at the sliding connection between the traverse fastener 75 and the traverse base 71, so that the traverse fastener 75 can be stably installed on the traverse base 71, and can be driven by the traverse screw 73 to move a certain distance along the traverse base 71.

[0057] like Figure 6 and Figure 7 As shown, preferably, a rotating base 80 is further provided between the transverse movement mechanism 70 and the vertical movement mechanism 62, one end of the rotating base 80 is rotatably connected to the vertical slide 60, and the other end thereof is detachably fixed to the transverse movement mechanism 70, and a rotating screw 83 is provided on the side of the vertical slide 60 facing the rotating base 80, and the rotating screw 83 is rotatably connected to the vertical slide 60, and is installed with a third knob 84; a rotating gear 81 is provided on the rotating base 80 corresponding to the side of the rotating screw 83, one side of the rotating gear 81 is fixed to the rotating base 80, and the other side thereof forms a threaded transmission connection with the rotating screw 83, so that rotating the third knob 84 can drive the rotating gear 81 and the rotating base 80 to rotate a certain angle relative to the vertical slide 60, thereby realizing the rotation operation of the transverse movement mechanism 70 and the sight assembly 90.

[0058] Specifically, since the rotating base 80 needs to be driven to rotate at a certain angle, the rotating gear 81 preferably adopts a gear with a section of annular gear teeth, so that the rotating screw 83 can continuously drive the annular gear tooth portion, thereby driving the rotating base 80 to rotate at a certain angle. In order to lock the rotating base 80, a locking bolt 82 can also be provided at the rotating gear 81, so that the locking bolt 82 can lock the rotating gear 81, thereby locking the rotating base 80.

[0059] Secondly, the rotation direction of the rotating base 80 is a lateral rotation relative to the circumferential direction of the aiming line, and the angle indication direction of the angle indicating device is a rotation operation on a different plane. The rotating base 80 mainly performs a rotation operation on the aiming star assembly 90, while the angle indicating device indicates the rotation angle of the arrow shooting direction of the bow itself. The two have different structures and different uses.

[0060] In another embodiment of the present invention, Figure 6 and Figure 7 As shown, preferably, the first track member 20 is provided with an inclined track.

[0061] Specifically, the first track member 20 can be provided with an oblique long hole 21 to form an inclined track, the first conversion member can be in contact with the inclined track, and a guide groove 41 (not shown in the figure) is provided on the side of the first driving member 40 facing the first conversion member, and the first conversion member can be provided with a corresponding driven rod 31, and the driven rod 31 is just embedded in the guide groove 41, and the side wall of the guide groove 41 is used to push the driven rod 31 to move upward or downward, and due to the oblique limiting effect of the inclined track, the first conversion member can be driven to move obliquely along the inclined track, thereby driving the first pointer to rotate a certain angle, and then indicating the corresponding elevation angle.

[0062] Since the distance between the first conversion member and the first driving member 40 will change when the first conversion member moves obliquely along the inclined trajectory, the guide groove 41 can be set to have a certain length so that the driven rod 31 can move laterally on the side wall of the guide groove 41.

[0063] In a second embodiment of the present invention, Fig. 9 As shown, preferably, the bending direction of the arcuate through hole 23 can be bent from right to left, and from top to bottom. This embodiment is the same as the main structure or components of the first embodiment, and the difference is that the bending direction of the arcuate through hole 23 is different, or the position of the starting end of the arcuate through hole 23 is set differently. Therefore, the arcuate through hole 23 in this embodiment will form a different moving trajectory for the conversion slider 30, and the linear relationship between the rotation angles of the long pointer 10 will also be different. According to the specific parameters of the bow and arrow, or the specific requirements for the angle change of the angle indicating device, the bending direction of the arcuate through hole 23 and the position of the starting end can be combined to optimize the setting to form a corresponding linear relationship.

[0064] Similarly, in the third embodiment of the present invention, as Fig.10 As shown, preferably, the bending direction of the arc-shaped through hole 23 can be bent from left to right and from top to bottom. The main structure or components of this embodiment are the same as those of the first embodiment, and the difference lies in the different position settings of the starting end of the arc-shaped through hole 23. In the first embodiment, the starting end of the arc-shaped through hole 23 is close to the rotating end of the long bar pointer 10. In this embodiment, the starting end of the arc-shaped through hole 23 is relatively far away from the rotating end of the long bar pointer 10.

[0065] Therefore, the arc-shaped through hole 23 in this embodiment will form different moving tracks for the conversion slider 30, and will also have different linear relationships between the rotation angles of the long pointer 10. According to the specific parameters of the bow and arrow, or the specific requirements for the angle change of the angle indicating device, the arc-shaped through hole 23 can be optimized and set in combination with the curvature, curvature direction or starting end position to form a corresponding linear relationship.

[0066] In summary, all embodiments of the present invention can achieve that when the vertical slide 60 is moved up and down for adjustment, the long pointer 10 can, driven by the first drive member 40 and the conversion slider 30, make corresponding angle changes and indicate the changed angle, thereby achieving the adjustment, indication or marking of the shooting angle of the bow and arrow, thereby improving the shooting accuracy of the bow and arrow and enhancing the user experience.

[0067] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
