The device includes a substantially T-shaped main body of two spaced apart members that are T-shaped, the crossbar of the body being adapted for manual gripping by the user with his hand in a palm down position, and the center leg of the body projecting forwardly therefrom. The crossbar and center leg 0 each member are in substantially a common plane. A string receiving first notch is formed in the forward end of the central leg. A rotatable member having a second notch formed therein is swingable between a cocked position, with opposite side portions defining opposite sides of the second notch extending transversely of the first notch, and a release position swung out of the way of the notch in the main body. An elongate catch arm is pivotally connected intermediate its ends to the main body. The forward end of the catch arm is shiftable between a holding position for retaining the holding member in its cocked position and a release position allowing release of the holding member. A trigger adjacent the other end of the operator arm is manually shiftable in opposite directions for swinging the catch portion between its cocked and release positions.
13 Claims, 7 Drawing Figures ARCHERY BOWSTRING RELEASE BACKGROUND AND SUMMARY OF THE INVENTION This invention relates to a device to aid an archer in drawing and releasing an archery bowstring.
Various types of devices have been designed in the past in an attempt to aid archers in drawing and releasing bowstrings. For the most part, such devices have not been successful, in that they have been either overly complex and cumbersome, have produced less than desired accuracy in release of the arrow, or have produced excessive wear on the bowstring in the region engaged by the device.
A general object of the present invention is to provide a novel device for drawing and releasing an archery bowstring which overcomes the above-noted objections of prior devices in a simple and efficient mantll.
Another object is to provide such a novel device which is simply and inexpensively constructed and is of convenient size and design for comfortable holding and to produce accurate arrow release.
Yet another object is to provide such a novel device for drawing and releasing an archery bowstring which produces minimal wear on the bowstring in the region engaged by the device.
A still further object is to provide a novel device for drawing and releasing an archery bowstring which may be left unattended on the bowstring when not in use.
A still further object is to provide a novel device for drawing and releasing an archery bowstring which may be operatively connected to a bowstring prior to drawing, merely by pressing the bowstring into a receiving notch in the device. The construction of the device is such that when the bowstring is pressed into the notch, a string holding member is moved into a cocked position and is held in this cocked position until manually released as desired by the user.
More specifically, the device of the invention includes a main body having an elongate handle portion and a string holding portion projecting outwardly at a substantial angle therefrom. The device is adapted to be held by a user with the handle portion substantially horizontal and the user's hand held palm down. The string holding portion projects substantially horizontally forwardly from the users hand. A forwardly opening string receiving notch, extending vertically in the device when used, is adapted to receive a string therein. A string holding member is pivotally mounted adjacent the string receiving notch in the main body and this member has a notch therein which coincides with the string receiving notch in the main body when the device is cocked. A side of the string holding member bounding a side of the notch therein holds a string in the notches when the device is cocked. On release of the holding member it is operable to swing toward the open end of the string receiving notch to release the bowstring therefrom. An operator arm pivotally mounted in the main body has a catch portion adjacent its forward end operable to hold the string holding member in its cocked position and a trigger adjacent its opposite end engageable by a users finger or thumb which may be shifted substantially horizontally to swing the catch portion of the operator arm out of engagement with the catch member to allow it to release the bowstring.

DETAIL DESCRIPTION OF AN EMBODIMENT OF THE INVENTION Referring to the drawings, and first more specifically to FIG. I, at 10 is indicated generally a device for drawing and releasing an archery bowstring constructed in accordance with an embodiment of the invention. A bowstring 12 is illustrated loaded in and drawn by the device. The rear, or nocked, end of an arrow 14 is illustrated in dashed outline nocked on the bowstring, and a users hand is illustrated in dashed outline at 16.
Describing device 10 in detail, it includes a pair of substantially parallel top and bottom plates 18, 20, respectively. Each of the plates has the somewhat T- shaped configuration as illustrated in FIGS. 1 and 2 for plate member 18 and as illustrated in FIG. 6 for plate 20. The plates have what may be referred to as crossbar, or handle, portions 18a, 20a and central leg portions, also referred to as string holding portions, 18b, 20b extending outwardly at a substantial angle from intermediate regions of portions 18a, 20a. The forward ends of these central legs each have a notch formed therein 18c, 200 which open to the forward end of the device.
Body plate 18 is planar and of substantially constant thickness throughout. The string holding portion 20b of body plate 20 and the central region of its handle portion 20a also are planar and of substantially constant thickness. Opposite end sections 20e, 20f of the handle portion, however, are of increased thickness, as is best seen in FIGS. 1, 3, 4 and 6. When the plates 18, 20 are placed in juxtaposed aligned, or registering, relationship, as illustrated, their forward notches 18c, 20c are aligned to define a common string receiving notch, or channel, which extends vertically through the forward end of the device when the plate members are held substantially horizontal and opens to the forward end thereof. Sections 20e. 20f of increased cross section act as spacer means to maintain string holding portions 18h, 20b, and central regions of the handle portions in positions spaced apart a preselected distance.
A pair of projections 24, 26 extend outwardly from sections 20e, 20f (see FIG. 6) and are received in accommodating bores in plate 20 when the device is assembled, thus to aid in initially establishing and maintaining alignment of the body plates. A screw fastener 30 extends through accommodating bores in plates I8, 20 to secure the plate members together.
A pivot post 32 (see FIGS. 57) is secured at one of its ends to a forward portion of string holding portion b and projects outwardly therefrom toward portion 18b. Mounted in the space between the forward ends of portions 18b, 20b and journaled for rotation on post 32 is a bowstring holding member 36 having the configuration illustrated in FIGS. S-7.
Member 36 includes an elongate arm portion 36a and a side portion 36b spaced therefrom which define a string receiving notch therebetween. The holding member is swingable about post 32 between what is referred to herein as a holding, or cocked, position as illustrated in FIG. 6 and a release position as illustrated in FIG. 7. In its cocked position, portions 36a, 36b extend transversely of notches 18c, 20c, with arm portion 360 adjacent the forward end of the notch, portion 36b adjacent the rear end of the notch, and the notch formed therebetween coinciding with a portion of the string receiving notch, or channel, in the body plates. In its release position, the holding member is swung forwardly whereby arm portion 360 swings laterally to the side of the string receiving channel, or notch, in plates 18, 20 to open the front end of such notch, whereby a string may exist therefrom. In this release position, as is best illustrated in FIGS. 5 and 7, a forward surface of arm portion 36b extends transversely of the string receiving notches, or channel, at the forward end of the main body.
As is seen in FIGS. 5-7, an elongate, arcuate opening 40 is formed in member 36. A stop post 42 secured at one of its ends to plate portion 20b and projecting outwardly toward plate portion 18b extends through opening 40. A compression spring 44 is interposed between posts 42 and an end of opening 40 to yieldably urge member 36 to rotate in a clockwise direction as seen in FIGS. 5-7 from its cocked toward its release position. The length of opening 40 is such that when member 36 is rotated to the positions illustrated in FIGS. 5 and 7, an end of opening 40 engages post 42 to act as a stop to limit rotation of the holding member to such posi tion.
An elongate arcuate operating, or catch, arm 46 is interposed between plates 18, 20 and extends through the space between sections 208, 20f acting as spacers. Arm 46 is pivotally mounted on the main body by being journaled intermediate its ends on screw fastener 30.
The outer, or forward, end of operating arm 46 has a hooked, or catch, portion 46a adapted to catch arm portion 36a of the string holding member is illustrated in FIG. 6 and hold it in a cocked position. The opposite end of the operating arm includes a trigger portion 461) which projects substantially normal to the plane of the major portion of the operating arm and is disposed adjacent one end of handle portions 18a, 20a of the plate members.
An elongate compression spring 54 (see FIG. 6) interposed between operating arm 46 and section 20] yieldably biases arm 46 to rotate the same in a clockwise direction as illustrated in FIG. 6 toward a holding, catch, position whereby it may engage and hold member 36. Rotation of operating arm 46 in a counterclockwise direction, against the urging of spring 54, shifts catch portion 46a of the arm to a release position as seen in FIGS. 5 and 7 which releases holding member 36 to allow it to rotate to its release position as seen in these figures.
An elongate adjustment screw 56 seen in dashed outline in FIG. 6, extends through a threaded bore in section 20 of plate 20. Operating arm 46 abuts an end of screw 56 when swung in a clockwise direction, with screw 56 thus providing an adjustable stop for selectively adjusting the extent to which catch portion 46a overlies portion 36a on holding member 36. The amount by which trigger portion 46b must be moved to release the bowstring thus may be selectively set to provide either a hair trigger or a less sensitive release.
Describing the operation of the device, the user first grips the handle of the device provided by portions 180, 20a, preferably with his index finger on one side of portions 18b, 20b and two fingers on the opposite side, with portions 18b, 20b extending forwardly between his fingers. With holding member 36 in its release position as illustrated in FIG. 5, bowstring 12 is inserted into the string receiving notch with the string substantially normal to plates 18, 20. The string is pressed against the forwardly facing surface of portion 36b. As the bowstring is pressed thereagainst, it rotates holding member 36 in a counterclockwise direction, against the urging of spring 44, toward the position illustrated in FIG. 6. The forward end of catch portion 460 is rounded to permit arm 36a to move thereover, urging the catch portion 46a away from the notch, until arm 36a is in the cocked position illustrated in FIG. 6. When the pressure of the bowstring has urged the holding member to the position shown in FIG. 6 catch portion 46a of operating arm 46 comes into a holding, or cocked, position overlying arm portion 360. Bowstring 12 then is held in the coinciding notches of the main body and holding member 36.
With holding member 36 thus held in its cocked position, the bow may be held upright and the device is held substantially horizontal with the user's hand 16 held palm down, as illustrated in dot-dashed outline in FIG. I. The bowstring then may be drawn with the users hand held palm down and this thumb against trigger portion 46b. When the bowstring has been drawn to a desired position and the arrow has been properly aimed, the user swings trigger 460 with his thumb in a substantially horizontal plane against the urging of spring 54. This rotates arm 46 about fastener 30 to swing catch portion 460 of the operating arm to the position illustrated in FIG. 7, thus to release the holding member. The holding member then swings to its release position under the urging of spring 44 and the tension in the bowstring, thus releasing the bowstring from the front of the notches.
With such construction, as the string is released the spring-rotated holding member swings outwardly and forwardly with the bowstring to produce minimum wear of the string and thus increase string life. The catch member does not engage the string, and thus there is no lateral movement of a face of the catch member across the string which may produce inaccuracies in release and wear on the string.
While a preferred embodiment of the invention has been described herein, it should be apparent to those skilled in the art that variations and modifications are possible without departing from the spirit of the invention.
