The disclosure generally relates to archery equipment and more particularly to a gated arrow rest.
Arrow rests are well known in the art. An arrow rest provides support to the arrow while the bow is being carried, drawn, released, and during the initial flight of an arrow until it departs the bow. In order for a rest to be effective the rest must offer enough support to the arrow to enable the bow to be carried and drawn safely without the arrow falling from the rest. The rest must impart minimal friction to the arrow to prevent parasitic kinetic energy losses. An arrow rest must be durable enough to withstand thousands of shots and rough handling without changing the point of impact. Ideally, the rest should have minimal contact with the fletching (feathers) on the arrow. Fletchings are an integral part of accurate arrow flight, and any contact to the fletchings can disrupt the arrow's flight, and rest induced damage to the fletchings can degrade the accuracy of the affected arrow.
U.S. Pat. 5,070,855 (Troncoso) discloses an archery rest that consists of two prongs that form a “U” shaped trough that is biased against the arrow by a spring. The arrow rests on the points of the two prongs. Troncoso provides an arrow rest that is sufficiently rigid and durable, imparts little friction to the arrow, and has minimal fletching contact, but does very little to prevent the arrow from falling off of the rest. With this style rest it is difficult for archers, especially beginners, to draw the bow without the arrow falling off of the rest.
U.S. Pat. No. 6,978,775 (Graf) discloses an arrow rest that consists of a plurality of radially disposed, inwardly projecting brush bristles. This style rest provides very good containment, but has a large amount of frictional losses and fletching contact. Additionally, the brush material is consumed during the shooting process, requiring frequent replacement of the brush material.
U.S. Pat. No. 6,994,080 (Yoder) discloses a similar variant of arrow rest to the Graf patent with the exception of rather than having a semi-continuous ring of inwardly projected, radially disposed bristles, there are three spaced apart arrow supports mounted to a ring at 120 degree intervals. These supports consist of a support shoe and a plurality of bristles that extend inwardly from the support shoe for supporting the arrow. The support shoe and brush bristles are located at 2:00, 6:00, and 10:00 o′clock as the rest mounted on the bow with the arrow located in the center of the ring. The arrow is loaded into the rest by placing the arrow in the slot in the ring between approximately 11:00 and 1:00 o'clock and pushing the arrow down between the 2:00 and 10:00 o'clock brushes. This style rest decreases the frictional losses and fletching wear associated with the Graf patent, but still suffers from significant brush wear and difficulty loading of the arrow into the rest. Additionally, it is possible for the arrow to fall down between the lower brushes, or be expelled upward between the two upper brushes, completely out of the arrow rest.
The present disclosure is directed to an arrow rest for retaining an arrow in a shooting position on an archery bow. The arrow rest includes a generally ring shaped structure surrounding a center opening. The ring structure includes a gap configured to receive the arrow in the center opening. A gate is pivotally attached to the ring structure and biased to extend across the gap in a closed position. At least one fixed arrow support is attached to the ring and extends into the center opening toward the shooting position. At least two pivoting arrow supports are pivotally attached to the ring and biased toward the shooting position of the center opening. The pivoting arrow supports are biased to capture the arrow against the fixed arrow support in the shooting position of the center opening and to rotate away from the shooting position when the arrow is launched from the archery bow.
The present disclosure is directed to a system and methods for providing a segmented ring shaped arrow rest that has three points of contact supporting the arrow. The contacts are located at approximately 0 degrees, 120 degrees, 240 degrees. The lower two supports are independently spring loaded launchers, preferably composed of a low friction thermoplastic. The upper support can be either another spring loaded device similar to the lower supports or a flexible brush. The three supports come together in the middle of the ring to form three points of contact with the arrow. The supports are disposed such that there is minimal fletching contact on the arrow on a standard three fletching arrow. A gap in the segmented ring is located between approximately 270 degrees and 315 degrees for a right handed shooter (45 degrees to 90 degrees for a left-handed shooter) for loading the arrow.
The two lower supports are spring loaded launchers mounted on threaded pins that are parallel with the loaded arrow. The launchers are biased upwards toward the arrow with torsion springs. During loading or on the shot, the torsion springs can be overpowered such that the launcher is allowed to rotate about the threaded pin, downward towards the bottom of the ring approximately 15 degrees.
In another exemplary embodiment, the gap in the segmented ring structure is closed with a spring loaded gate. The ring is adapted to accept the gate such that it hinges either at the top or the bottom of the gap in the ring.
In another exemplary embodiment, the gate is disposed such that when the gate is pushed open with the arrow, the gate displaces the spring loaded launcher and allows the arrow to be loaded into position with diminished interference.
An advantage of the present disclosure is that it allows for diminished frictional losses imparted to the arrow due to the low friction, spring loaded launchers.
Another advantage of the present disclosure is that it offers improved accuracy due to the lack of fletching contact with the brushes.
Yet another advantage of the present disclosure is that it reduces the wear associated with brushes supporting the bottom of an arrow during the shot. This reduces the inaccuracies associated with the degradation of the brush material.
Yet another advantage of the present disclosure is that the gate prevents the arrow from leaving the rest should the arrow be bumped while an arrow is loaded.
Yet another advantage of the current disclosure is that the gate assists in the loading if the arrow by displacing the lower launcher. This feature reduces the effort required to load the arrow and reduces the noise resulting from loading the arrow. The gate assisted loading also allows for the launchers to be disposed in a much tighter arrangement, greatly reducing the chance for the arrow to fall off of the launchers while the bow is being drawn and shot.
These exemplary embodiments are mentioned not to summarize the disclosure, but to provide an example of an embodiment to aid in the understanding. Exemplary embodiments will be discussed in the Detailed Description, and further description of the disclosure will be provided there. Further advantages will be understood by examining these specifications.
The accompanying drawing, which constitutes part of the specification, helps to illustrate embodiments of the disclosure.
The arrow rest 20 includes a segmented ring 28 with center opening 30 configured to receive an arrow (see e.g.,
Within the center opening 30 is a pair of pivoting lower supports 32A, 32B (“32”), preferably located at 120 degrees and 240 degrees relative to the ring 28. In the illustrated embodiment, the lower supports 32 pivot around axes 34A, 34B (“34”) and are biased upward to engage the arrow (see e.g.,
Upper support 36 can be either another pivoting spring loaded device similar to the lower supports 32 or a flexible structure, such as a brush. The three supports 32, 36 come together in the center 38 of the ring 28 to form three points of contact with an arrow. The center 38 is also referred to as the shooting position.
The lower supports 32 are pivotally attached to the ring 28 by pivot pins 34. Springs 62 bias the lower supports 32 into engagement with the arrow (see
Force 74 overcomes the biasing force of the gate spring 64 and pushes the gate 40 to the open position 76 illustrated in
The supports 32, 36 are located at 120, 240 and 0 degrees, while the arrow fletching 70A is located at 45, 180 and 315 degrees, so there is minimal contact with the supports 32, 36. As noted above, the supports 32 are biased by springs 62 toward the center 38 to retain the arrow 70 in the shooting position 38. When the arrow 70 is launched, the torsion springs 62 are overpowered such that the supports 32 rotate in direction 80 about 15 degrees toward the ring 28, and out of engagement with the arrow 70.
