摘要： An improved mechanical bowstring release device automatically biased to the locked position comprises a hollow, preferably generally cylindrical housing having a central space along the length thereof and a bowstring retainer bar pivotally secured to the housing in the space. A string-retaining end of the bar extends into an opening in the front end of the housing. The bar also includes an opposite coupling end. The bar is pivotable between a bowstring-drawing locked position and a bowstring-releasing unlocked position. An elongated lever arm extends longitudinally of and is pivoted in the housing space, the rear portion thereof extending rearwardly of the housing, the front end thereof being adjacent and generally rearward of the retainer coupling end. One or more couplers connect the front end of the lever arm and the coupling end of the bar. A biasing spring automatically urges the front end of the arm into a position which locks the bar. Finger pressure against the arm rear end results in pivoting of that arm front end to cause movement of the couplers and bar coupling end to cause the bar to pivot into the unlocked string-releasing position. A retainer limit component is also present to prevent rotation of the retainer bar to an unlocked position unbiased by the biasing spring toward the locked position.

Finger pressure against the arm rear end results in pivoting of that arm front end to cause movement of the couplers and bar coupling end to cause the bar to pivot into the unlocked string-releasing position. A retainer limit component is also present to prevent rotation of the retainer bar to an unlocked position unbiased by the biasing spring toward the locked position. The device operates smoothly in a safe efficient manner, and the retainer bar can be fully manipulated solely by the lever arm to couple the device to and uncouple it from a bowstring.

摘要： An improved mechanical bowstring release device has a hollow, preferably generally cylindrical housing having a central space defined by a pair of spaced flanges and a retainer bar pivotably secured to the housing in the space, one end of the bar projecting from the housing when the bar is pivoted into a bowstring-drawing locked position, the bar also being pivotable to a bowstring-releasing unlocked position. A link extends longitudinally of and is pivoted in the housing space and the rear portion thereof defines a V-shaped rearwardly facing receptacle into which is inserted the pointed front portion of a trigger arm. The arm is pivotably secured in the housing space and is rearwardly and laterally of the housing. Couplers connect the front end of the link and the coupling end of the bar. A spring urges the front end of the arm into a position which locks the bar. Finger pressure can pivot that arm front end to cause movement of the link, couplers and bar coupling end to cause the bar to pivot into the unlocked string-releasing position. The device operates smoothly in a safe efficient manner.

摘要： An archery peep sight adapted to be mounted on the bowstring of an archery bow for aligning the path of an arrow. A disc having a centrally located sight opening is attached to the bowstring in fixed space relation with the nocking point on the bowstring. The axis of the sight opening is coextensive with the axis of the disc and is located on the central plane of the disc. A frusto-conical surface is disposed inwardly from a first end of the disc, the apex thereof being terminated at the sight opening. A semi-conical recess is formed in the second end of the disc, the recess defining a horizontal planar surface adjacent the sight opening. Bowstring receiving channels are formed on opposite sides of the disc, the angular interval between a line normal to the bowstring receiving channels and the axis of the sight opening of the disc being in the range of 38.degree.-50.degree..

摘要： A pull-down type arrow rest support for an archery bow is disclosed. The downward motion of the lower limb tip as the bow changes from its drawn position to its relaxed position is used to pull down the arrow rest support out of the path of the arrow. There is no need for cocking the device each time before an arrow is fired, and the pulled-down arrow rest support clears even the largest fletchings so that the arrow is not deflected from its intended path. The arrow rest support disclosed makes it possible to use a V-spool rest or can be adapted to use other commercially available arrow rests. Provisions are made for precise vertical and horizontal adjustments of the arrow position, and the V-rest can be adjusted to accommodate any size arrow.

摘要： A latch for securing a printed circuit board adjacent one side of a television chassis wall comprises a T-shaped tongue having a stem connected at one end to the bottom of a plastic body, the other end of the stem adjoining a crossbar. The latch also includes a U-shaped groove disposed adjacent to the top of the body along a major surface thereof for receiving an edge of the printed circuit board. The chassis wall has a neck defined by two shoulders spaced apart to support, respectively, L-shaped arms connected to each side of the body at the bottom thereof. The tongue passes through a T-shaped aperture in the wall beneath the neck such that the crossbar contacts the side of the chassis wall opposite the one side, the aperture being shaped to allow the crossbar to pass therethrough before making contact with the opposite side of the chassis wall.

摘要： The two-wheeled vehicle assembly includes a motorcycle, motorbike or powered bicycle having a frame, a pair of wheels, one behind the other, a steering column, including a pair of handlebars and handles, a seat and a motor, and a throttle, throttle linkage as well as a throttle control, the latter connected to one of the handlebars, directly or indirectly. The assembly also includes a moveable auxiliary steering device which extends rearwardly from at least one of the handlebars or steering column, adjacent the seat and which enables the rider to lean back in a relaxed position in the seat, with his or her hands off of the handlebars and still be able to fully and precisely steer the vehicle. The auxiliary steering device can be made to pivot out of the way when desired and is individually repositionable for maximum ease and convenience. It includes an elongated arm, preferably with multiple articulated sections. It may also have a rotatable rear handle connected to the rear end of a wire throttle control extension, the front end of which is connected either to a wheel secured to a rotatable throttle control sleeve in one of the handlebars or directly to the carburetor throttle linkage. The assembly is simple, durable and efficient, permitting full steering and speed control while the rider is in a relaxed semi-reclining posture on the seat.

摘要： A bowstring draw and trigger release for use with conventional archery bows and the arrows used therewith. The bowstring draw and trigger apparatus provides means for drawing a bowstring taut and releasing same to project the arrow upon the triggering of the apparatus. The bowstring draw and trigger release utilizes a looped draw cord which is disposed about the bowstring and secured by a pivotally mounted holding member. The holding member pivots about a fixed shaft, an end thereof being coupled to the trigger of the apparatus. Actuation of the trigger causes the rotation of a directly coupled member which engages the holding member causing same to rotate forwardly allowing the loop to slide therefrom and thereby release the bowstring. There is a coupling member that directly slidably couples the trigger with the holding member. The respective ends of the coupling member are received between flanges of the trigger and the holding member.
