摘要:An improved archery bowstring release device is provided which includes ahousing having a rear finger-receiving portion and a front portion, the latter withforwardly projecting flanges disposed in vertically spaced relation to define a

longitudinal space therebetween. A bowstring draw cord defining a loop is preferablysecured to the flanges and projects from the housing. A draw cord loop retainer ispivotally secured in the space to the flanges for movement between a locked bowstring-retaining position and an unlocked bowstring-releasing position. If desired, the retainercan be used directly to draw the bowstring rather than utilizing the draw cord, and thedraw cord can then be removed from the device. The retainer projects laterally andrearwardly from the housing when in the locked position.

A trigger mechanism is provided which comprises a coupler extending longitudinally inthe space and pivotally connected to the flanges adjacent its rear end and to a linkadjacent its front end, the link in turn being pivotally secured to the loop retainer. Anelongated trigger arm extends longitudinally of the housing and is pivoted thereto sothat its front end engages the rear end of the coupler. The arm's rear end extendsrearwardly from the housing and is urgeable transversely of the housing by the archer'sthumb to cause the front end thereof to force the coupler and link to rotate the retainer

from the locked (cocked) position to the unlocked position, thus releasing the bowstring.The retainer can be easily manually moved back to the locked position. The device isinexpensive, durable and efficient, permitting easy, sure and highly accurate andreproducible drawing and shooting of archery arrows.
