Archery Paper Tuning Device

Abstract

An archery arrow trajectory evaluation device, that is suspended from above by a pair of cords. Holds a paper roll above a framed structure. The paper feeds down in between the front and back frame. Frames are held together with hollow screws and nuts in each corner. Each nut is adjustable allowing the user to tighten the front and back frame together to hold the paper taut on four sides, but still allowing the paper to pass through from the top of the frame down through to the bottom. Once the paper is held securely between the frames an arrow may be shot through the center of the frames to determine the trajectory of the arrow. If the bow is tuned the arrow will pass through the paper and the tear left behind will be symmetrical. The tear will indicate to the user what adjustments are needed.

Archery enthusiasts and professionals have long sought to optimize the performance of their equipment to achieve consistent and accurate arrow flight. One common method employed for this purpose is known as “paper tuning.” Paper tuning involves shooting an arrow through a sheet of taut paper at close range to assess the arrow's flight characteristics by analyzing the tear pattern on the paper. The resulting tear pattern can provide insights into potential issues such as nocking point alignment, arrow rest positioning, arrow issues, and other bow tuning variables. Existing paper tuning devices include floor stands that are mobile, floor stands that are fixed to the floor, or wall mounted. The current options that are available don't hold the paper on all four sides so the paper is not held taut in all four directions. This invention solves that by utilizing a front and back frame to hold the paper on all four sides. This device is unique in that is takes up no floor space because it is suspended from above.

Other patents and publications have addressed various aspects of archery equipment tuning and arrow flight analysis. For example, U.S. Patent No. US-20090026708-A1 describes a method and apparatus for analyzing arrow flight by utilizing a floor stand with adjustable legs that holds a paper roll at the top of the device frame with a dowel. This device incorporates a clamping pressure bar to keep the paper from moving. The paper is held taught at the top and bottom of the device.

However, prior art solutions fail to provide a comprehensive and user-friendly system for paper tuning that is both easily adjustable, does not take up any floor space, mobile, and easy to store. There remains a need for an improved archery paper tuning device that offers enhanced features, simplicity of use, and objective analysis of arrow flight characteristics. The present invention addresses the shortcomings of the related art by introducing an innovative archery paper tuning device that securely holds the paper on all four sides, provides adjustable positioning, takes up no floor or wall space, easy to move and store. While still providing assessment of arrow flight. By doing so, the present invention offers a novel solution for archers to effectively diagnose and rectify equipment setup issues, ultimately leading to improved accuracy and performance.

BACKGROUND OF THE INVENTION

The present invention relates to the field of archery equipment and tuning tools. More specifically, the invention pertains to an archery paper tuning device designed to enhance the accuracy and consistency of archery equipment by analyzing arrow flight characteristics through the tears made on paper as an arrow is shot through it. The device facilitates the assessment and adjustment of various factors affecting arrow flight such as the arrow rest alignment, arrow nock point, and other related aspects to bow tuning. The archery paper tuning device provides archers with a valuable tool to diagnose and correct equipment setup issues for improved shooting accuracy and performance. The present invention addresses some of the challenges associated with current paper tuning systems and devices. This device takes up no floor space and is suspended from the ceiling or any other structure above the tuner by two parallel cords. It is uniquely designed to hold a roll of paper using a rod above the tuner to allow the paper to feed down from the roll through the front and back frame of the tuner and be held on all four sides keeping the paper taut, and then pass through the bottom of the frames so the user can easily pull the paper downward to advance the paper as it's being used for tuning the bow. The unique design of the frames allows the paper to be held taut on all four sides and it can be adjusted by the user with four adjustment screws, one in each corner. The design of the front and back frame, work together to allow for easy feeding of the paper from the top in between the two frames. There is special consideration taken on the design of the bottom section of the tuner to help the torn paper to exit the bottom section without getting stuck or impeded by the paper tears.

SUMMARY OF THE INVENTION

The present invention is mounted from above and suspended with two cords laterally spaced and parallel to each other, so it does not require any floor space. There are adjustable cord stops to allow the user to adjust the tuner to their height. Its function is to hold a roll of paper on a rod above a frame and then dispense the paper through the frame keeping the paper taut and allowing the exposed paper in the center of the frame to facilitate the passage of an arrow shot from a bow. The tear in the paper is then used to diagnose any issues with the bow's set up. The ideal tear in the paper would be a perfectly symmetrical hole if shot with a bare shaft, or a symmetrical hole with evenly spaced tears from the fletching's. Other observations are an indication that the arrow is not flying true. The paper is held on all four sides. This enables the paper to be taut but also allows the paper to pass through with ease from top to bottom. There is a front and back frame that holds the paper in place. There are four hollow screws and nuts one in each corner of the frame. This holds the paper in place but also gives the user the ability to adjust the tension on the paper. The front and back frames are slightly different in size. It was engineered to allow the user to feed in the paper at the top of the frame and then feed it through at the bottom of the window and then out the bottom of the frame. There is also a beveled edge on the back side of the front frame at the bottom of the window. This helps facilitate the passage of the paper with tears. Due to the size, weight, and how it's attached from above it can easily be taken down to be moved or stored.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 and FIG. 4 illustrate the mechanism for holding the paper roll 111 and frames 101, 103. The cord 117 as it descends from above passes through the adjustable cord stopper 109 then through a hollow rod 113 then passes through the front of the device through a hollow screw 105 then out the back of the device through the hollow screw 105 and adjustable nut 107. The cord then goes back through the hollow rod 113 and back through the cord stopper 109. This is the second location where the user can adjust the height of the tuning device to tailor to their individual stance and height. The rod 110 holding the paper roll 111 is held securely in place by the cord 117 in the front and back of the rod while the adjustable cord stopper 109 holds it in place from above, and the hollow rod 113 holds it in place from below. The front frame 101 and the back frame 103 are held together with four hollow screws 105 that are inserted from the front frame and exit out the back frame and secured together with a hollow nut 107. The paper 111 is inserted in between the top of the front frame 101 and the back frame 103. It then passes through until exiting out the bottom of the frames. FIG. 5 illustrates a difference in the height at the top of the front frame 101 and back frame 103. This is intentional to allow for easier insertion of the paper by the user. In FIG. 6 it illustrates a space between the bottom of the back frame 103 and the front frame 101. This space is intentional to allow the user to remove the paper. FIG. 5 demonstrates how the paper 111 is securely held in place on all four sides of the device. This is critical for keeping the paper taut for paper tuning. The user can adjust the tension on the paper with the screws 105 and nuts 107 in each corner. The paper is secured by the front 101 and back 103 frames on all four sides with a considerable amount of the surface area holding the paper in place, so the frames only need to be tightened to a point at which the paper pulls out with minimal effort by the user. The paper cannot escape the device once it has been inserted from the upper end to the lower end. The screws 105 act as stops on each side and help guide the paper through the frames. FIG. 7 illustrates the bottom section of the back side of the frames. The bottom ledge of the window on the front frame 101 has a beveled edge 112 that is integrated into the back side of the front frame. The lower section of the back frame 103 window ledge is lower than the front frame. This is intentional to help facilitate the passage of paper with tears through the bottom section of the front 101 and back frames 103. FIG. 5 and FIG. 6 illustrate the passage of the paper 111 from the base of the frames. The user will pull on this section of the paper to advance the paper to remove the utilized segment with tears from the window section of the device.

It is understood that the preceding description is given merely by way of illustration and not in limitation of the invention and the various modifications may be made thereto without departing from the spirit of the invention as claimed.
