ABSTRACT:
TECHNICAL FIELD
This invention relates to bowstring release devices and, more specifically, to a bowstring release device with an adjustable trigger, and with a new and improved wrist strap connector.
BACKGROUND
Various release devices are utilized in archery to assist the archer in pulling a bowstring to a fully drawn position and then releasing the bowstring to fire the arrow. Many of these devices include mechanical grippers which engage the bowstring directly, or which engage nock elements mounted on the bowstring. Other devices use rope looped about the bowstring as the release mechanism.
It is also known to use wrist straps connected to the release devices to enhance control and accuracy of the release device. Examples of such wrist straps may be found in U.S. Pat. Nos. 5,020,508; 4,981,128; 4,791,908; and 4,509,497.
SUMMARY OF THE INVENTION
The present invention relates to an improved bowstring release device and wrist strap, including an adjustable trigger on the release, and a novel connector by which the release is connected to the wrist strap.
In the exemplary embodiment, a bowstring release device of the type disclosed in U.S. Pat. Nos. 5,680,851; 5,685,286; and 5,937,842 has been modified to incorporate an adjustable trigger which permits the trigger element itself to be oriented in four different positions relative to the trigger actuation lever extending into the release body. This allows the user to customize the release to provide a comfortable feel during the firing procedure. This is achieved by having the trigger element separable from the actuation lever and by providing a series of detents in the actuation lever for selective engagement with a tab on the trigger element. Once the trigger element is moved to the desired orientation, it can be tightened by means of a fastener such as a set screw or the like.
The release device is secured to the wrist strap by means of an extended rod threadably received at one end in the release body, and secured at its opposite end to a connector attached to an otherwise conventional wrist strap. The connector has a generally triangular orientation, with an elongated slot along the base of the triangle. At the apex or forward end of the triangle, there is a raised boss having a smooth but tapered bore therein which receives the threaded rod extending away from the bowstring release. The rod passes through the boss and is secured by a nut. Tapering of the bore allows greater freedom of movement of the release relative to the wrist strap. It will also be appreciated that by tightening the nut on the connecting screw at the connector may be tightened thus adjusting the draw length of the device.
The connector is secured to the wrist strap by means of a nylon web stitched onto the underlying wrist strap after the nylon web is passed through the slot in the connector. The nylon web is then also stitched adjacent the slot where the web is folded partially onto itself, thus permanently holding the connector in lace. With this arrangement, the connector as well as the release is pivotable through 180° from a straightforward position, to a position where the release is essentially folded back onto the user's wrist.
Accordingly, in its broader aspects, the present invention relates to a bowstring release comprising a release body having a pair of jaws actuated by a trigger, the trigger including a trigger actuator and a trigger lever adapted to seat in any one of plural predetermined positions relative to the trigger actuator to thereby enable adjustment of the trigger relative to the release body.
In another aspect, the invention relates to a bowstring release comprising a release body having a pair of jaws actuated by a trigger; and a wrist strap operatively connected to the release body by an elongated link threadably connected at one end to the release body and at an opposite end to the wrist strap, and including a connector between the link and the wrist strap, the connector pivotally mounted to the wrist strap.
In still another aspect, the invention relates to a bowstring release comprising a release body having a pair of jaws actuated by a trigger, the trigger including a trigger actuator and a trigger lever adapted to seat in any one of plural predetermined positions relative to the trigger actuator to thereby enable adjustment of the trigger relative to the release body; and a wrist strap operatively connected to the release body by an elongated link threadably connected at one end to the release body and at an opposite end to the wrist strap, and including a connector between the link and the wrist strap, the connector pivotally mounted to the wrist strap.
