ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to adjustable arrow rests, and more particularly pertains to an improved adjustable arrow rest which provides a visual indication of amount of deflection of arrow rest launcher support arms after each shot. The present invention relates to an adjustable arrow rest of the same general type as the adjustable arrow rest disclosed in U.S. Pat. No. 5,117,803 which issued to Steven C. Johnson on Jun. 2, 1992, the entire disclosure of which is incorporated herein by reference.
SUMMARY OF THE INVENTION
An adjustable arrow rest includes an elongated mounting plate provided with a plurality of threaded apertures to facilitate securement of the mounting plate to a bow. The arrow rest also includes a slide block having vertical and horizontal leg portions provided with independently adjustable lead screw mechanisms which allow the precision adjustment of the position of arrow rest launcher arms in vertical and horizontal directions. A substantially vertically extending guide rib disposed adjacent one end of the mounting plate engages a complementary guide channel on the vertical leg portion of the slide block, mounting the slide block for selective reciprocal linear adjustment in a substantially vertical direction relative to the mounting plate. A housing block portion of the arrow rest includes a guide rib disposed in engagement with a complementary guide channel formed on the horizontal leg portion of the slide block, mounting the housing block for selective linear reciprocal movement in a substantially horizontal direction relative to be slide block. A pair of bushings mount a rotary sleeve within a transverse central bore extending through the housing block. A torsional coil spring surrounds the rotary sleeve and provides a restorative spring force. An adjustment dial secured to one end of the torsional coil spring allows selective adjustment of the restorative spring force. A pair of launcher arms are secured adjacent one end of a cylindrical shaft secured for rotation within the rotary sleeve by a pair of set screws. The spring adjustment dial includes an outer face provided with a scale that cooperates with an indicator member to provide a visual indication to an archer of the amount of deflection of the arrow rest launcher arms after each shot. The visual indication of deflection allows an archer to make appropriate adjustments to his or her equipment and/or technique.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto. In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting. As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
