This application is a non-provisional of U.S. Patent Application Ser. No. 61/883,422 (filed Sep. 27, 2013) and U.S. Patent Application Ser. No. 61/884,493 (filed Sep. 30, 2013) the entirety of which are incorporated by reference.
The subject matter disclosed herein relates to archery releases and to triggerless back tension releases in particular.
Archery releases are designed to hold a bowstring so that an archer can pull on the release and draw the bowstring with the release. Archery releases assist the archer in cleanly and consistently releasing the bowstring when the archer shoots an arrow from the bow. This increases the accuracy of the archer's shot.
There are a variety of archery releases available including trigger releases and back tension releases. A trigger release typically includes a trigger mechanism and one or more moveable jaws joined with the trigger mechanism. The moveable jaws are configured to hold a bowstring of a bow. When activated by the archer's finger, the trigger mechanism moves the moveable jaws to release the bowstring. A back tension release typically includes a release handle, a release head bracket pivotally secured to the handle, and a hook pivotally secured to the release head bracket. The hook is configured to hold the bowstring, and is also adapted to engage a pawl. To operate the release so that it releases a bowstring held in the hook, an archer holds the handle, and squeezes the archer's shoulder blades together or, in other words, “tense their back.” Because the archer holds the device in their hand by the handle, tensing of the back muscles moves the hand and, in turn, rotates the release slightly. This slight rotation moves the release enough so that the hook disengages the pawl, and thereby becomes free to move and release the bowstring. The discussion above is merely provided for general background information and is not intended to be used as an aid in determining the scope of the claimed subject matter.
A triggerless back tension archery release is provided. Disclosed archery releases include a bearing ring that rotates relative to a release body. During use, the bearing ring rotates to the same position when force is applied during a draw cycle. This reduces inconsistent placement of the finger and provides consistent release alignment. Disclosed archery releases also include a variety of removable finger extension that provide high mass triggers. An archer can feel subtle movement of the high mass triggers with increased accuracy which provides better control over the archery release.
An advantage that may be realized in the practice of some disclosed embodiments of the back tension archery release is that a more uniform finger placement is provided due to a rotatable bearing ring that reaches a reproducible position when force is applied during use.
In a first embodiment, a triggerless back tension archery release is provided. The release comprises a release body comprising a hole defining a first finger position for receiving an index finger, a first bearing ring and a second bearing ring, each having a collar and a lip. The lips engage the release body to secure the first bearing ring and the second bearing ring within the hole. The collars pass through the hole and engage one another to secure the first bearing ring and the second bearing ring to one another while permitting free rotation relative to the release body. A finger extension is connected to the release body. A triggerless hook assembly is connected to the release body that is configured to selectively release a bowstring upon actuation of the finger extension.
In a second embodiment, a triggerless back tension archery release is provided. The release comprises a release body comprising a hole defining a first finger position for receiving an index finger, a ring-shaped bearing disposed in the hole, a first bearing ring and a second bearing ring, each having a collar and a lip. The lips engage the release body to secure the first bearing ring and the second bearing ring within the hole. The collars pass through the hole and through the ring-shaped bearing, the collars engaging one another to secure the first bearing ring and the second bearing ring to one another while permitting free rotation relative to the release body. A finger extension is connected to the release body. A triggerless hook assembly is connected to the release body that is configured to selectively release a bowstring upon actuation of the finger extension.
This brief description of the invention is intended only to provide a brief overview of subject matter disclosed herein according to one or more illustrative embodiments, and does not serve as a guide to interpreting the claims or to define or limit the scope of the invention, which is defined only by the appended claims. This brief description is provided to introduce an illustrative selection of concepts in a simplified form that are further described below in the detailed description. This brief description is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. The claimed subject matter is not limited to implementations that solve any or all disadvantages noted in the background.
So that the manner in which the features of the invention can be understood, a detailed description of the invention may be had by reference to certain embodiments, some of which are illustrated in the accompanying drawings. It is to be noted, however, that the drawings illustrate only certain embodiments of this invention and are therefore not to be considered limiting of its scope, for the scope of the invention encompasses other equally effective embodiments. The drawings are not necessarily to scale, emphasis generally being placed upon illustrating the features of certain embodiments of the invention. In the drawings, like numerals are used to indicate like parts throughout the various views. Thus, for further understanding of the invention, reference can be made to the following detailed description, read in connection with the drawings in which:
In use, an archer places a bowstring of a bow within a bearing hook 110. In the embodiment of
Some archers prefer to use a particular number of fingers when using a release. Examples of such preferences include two-finger releases, three-finger releases and four-finger releases. Other archers prefer the reverse. The removable finger extensions 104, 204 permit archers the option of connecting a preferred finger extension to a common release body 102.
The finger extensions are weighted to provide better control in the shooting of the release. In one embodiment, at least about 50% of the release's total weight is in the finger extension. In one embodiment, the finger extensions consist essentially of a metal, such as stainless steel or aluminum. In one exemplary embodiment a three-finger extension that consists essentially of stainless steel has at least about 55% of the release's total weight in the finger extension. Likewise, a three-finger extension that consists essentially of aluminum has at least about 18% of the release's total weight in the finger extension. In the exemplary embodiment of
This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal language of the claims.
