Wingnut adjustment tool

Abstract

A self-contained folding wingnut tool for a variety of wingnut applications including percussion instruments. The tool has a hinged clamshell housing with multi-spaced pairs of upstanding wingnut engagement elements aligned to engage and adjustably turn wingnuts of various dimensions therebetween. Each pair of upstanding wingnut engagements form opposing space contoured frictional engagement surfaces for the registration with respective portions of a wingnut, positioned therebetween. The opposing spaced wingnut engagement pairs extend from wingnut engagement portion of the hinged housing inwardly from its free end, so when opened and extended an oppositely disposed portion handle is formed by the opposite housing portion for leverage and enclosure when closed.

DETAILED DESCRIPTION OF THE INVENTION

(8) Referring to FIGS. 1 and 2 of the drawings, a compact folding wingnut tool 10 of the invention can be seen having centrally hinged elongated housing 11 with a handle extension portion 12 and a wingnut engagement portion 13. The housing 11 is formed with an integrated hinge 14 defined from adjoining overlapping end portions of the respective handle and wingnut portions 12,13 respectively, as will be described in greater detail hereinafter.

(9) The elongated housing 11 is transversely curved defining concave interior surfaces extending inwardly from their respective free ends and diminishing to the hinge 14, which is formed from multiple overlapping aligned tabs 15A, 15B extending from each of the respective housing portions and containing a center hinge pin 16 therethrough.

(10) It will be evident from the above description that each of the respective housing portions are of the equal dimension so when brought together in a clamshell fashion as seen in FIG. 6 of the drawings they are registerably engaged to one another in a continuous contoured external exterior shape.

(11) The wingnut engagement portion 13 has pairs of upstanding spaced aligned effacing wingnut engagement elements 19, 20 extending integrally from the corresponding interior side surfaces 13A, best seen in FIGS. 1, 2 and 5 of the drawings. Each of the engagement pairs 19, 20 are identical having a first and second identical effacing tab elements 21A, 21B. Each of the respective tab elements 21A, 21B are formed from an upstanding support tab portion 22 extending at right angles from the respective interior side edge surfaces 13A, as seen best in FIGS. 1 and 2 of the drawings.

(12) Each of the tab portions 22 have an elongated curvilinear end extension portion 23 there across, extending the length of a tab end edge 22A and correspondingly outwardly in oppositely disposed equal relation therefrom to the bottom interior surface 13B of the wingnut engagement portion 13.

(13) Each of the respective tab elements 21A, 21B are in aligned space relation to one another, defining a wingnut receiving gap at 24 therebetween, best seen in FIG. 2 of the drawings.

(14) Referring now to FIG. 5 of the drawings, each of the respective tab portions 22 have a contoured upper free edge 22B that extends from an upper edge 13C of the interior side surface 13A to the corresponding top edge of the end extensions 23, which is of the greater height as indicated by height line HL.

(15) It will therefore be seen that the effective wingnut receiving gaps at 24 between the respective tab elements 21A, 21B are of an increased depth to accommodate a variety of dimensional aspects of wingnuts W that one may encounter, providing a universality to practical use of the wingnut tool 10 of the invention and a variety of applications, as seen in broken lines in FIG. 2 and solid lines in FIG. 7 of the drawings.

(16) The wingnut engagement element pairs 19, 20 as noted are positioned within the wingnut engagement portion 13 with the specific engagement element pair 20 positioned inwardly of a free end edge 24A of the wingnut engagement portion 13 wherein the effective longitudinal spacing between the respective identical aligned wingnut engagement pairs 19, 20 is proportional equal to approximately one-third of the overall length of the wingnut engagement portion 13 from its free end 24 to the center spaced hinge 14, as best seen in FIG. 1 of the drawings.

(17) This orientation thereby defines the positioning of the respective wingnut engagement pairs 19, 20 at the corresponding end area of the wingnut portion 13, assuring the lever action advantage with the handle portion 12 extended for use, as noted hereinbefore.

(18) Referring now to FIGS. 3 and 4 of the drawings, a belt retainer clip 26 can be seen which is secured to the outer convex surface 27 of the wingnut engagement portion 13, having an elongated flat main body member 26A with an apertured offset attachment mounting portion 26B extending therefrom. A fastener F extends through the apertured offset attachment mounting portion 26B and through a corresponding aligned opening 28 in the wingnut engagement portion 13, adjacent to hinge 14 as seen in FIGS. 1 and 3 of the drawings. This provides for a convenient carrying mount for the wingnut tool 10 when in folded transport position, as shown in FIG. 4 of the drawings, as will be well understood by those skilled in the art.

(19) The compact folding wingnut tool 10 of the invention is preferably made out of molded synthetic resin material with the hinge 14, as hereinbefore described formed by the integral extending apertured spaced tabs 15A, 15B on each of the respective body members 12, 13 which are engaging to one another and held in place as noted by a retainment hinge pin 15 there through.

(20) It will thus be seen that a new and novel compact folding wingnut tool 10 has been illustrated and described, and will be apparent to those skilled in the art that various changes and modifications may be made thereto without departing from the spirit of the invention.
