Definitions

  • This invention relates to rotary tools of the type used in rotating or "wrenching" fasteners such as bolts and screws having polygonal (e.g., square or hexagonal) heads.
  • the invention particularly relates to tools capable of wrenching fastener heads designed, sized or marked in various measuring systems such as the metric system, the English or inch system such as the American fractional system (AF and SAE), and the British systems such as BA, BS and Whitworth (W).
  • U. S . Patent 3,027,790 discloses a wrench-having several moving parts as adaptors and does not appear to represent a practical solution to the problem, since professionals and serious amateurs appear to prefer solid one-piece wrenching tools with no extraneous parts.
  • the invention in one embodiment provides simple, single piece rotary wrenching tools having uniform interior configurations and no moving parts and which are specifically sized for turning fasteners (nuts, screws, bolts, etc.) having square, hexagonal or other polygonal heads such that one tool size is capable of strongly and adequately fitting polygonal heads nominally sized in at least two and up to six different nominal sizes and up to seven different system markings.
  • rotary tool By "rotary tool”, “spanner” or “wrench”, as used herein, reference is made to tools having openings which completely or partially encircle or encompass the polygonal heads of threaded fasteners such as bolts and screws to rotate the fasteners.
  • such tools may be of the socket variety in which the rotary tool opening completely encircles the head of the threaded member and is moved into such position axially of the threaded member, or may be of the spanner or open-end wrench variety in which the rotary tool opening only partially encircles the head of the threaded member and may be moved into its wrenching position in a direction generally normal to the axis of the threaded member.
  • Rotary tools include such tools as may commonly be referred to as socket wrenches, box-end spanners, ratcheting box-end, open end, nut drivers, flare-nut, lug-nut, crowfoot and combination wrenches, impact and power socket wrenches, flex-head wrenches, etc.
  • wrenching tools which are adapted for use with threaded members having square heads are so sized as to accommodate maximum and minimum sized square-headed members such that the maximum ratio of the nominal distance across opposing flats of such maximum and minimum square-headed members ranges from about 1.0053 to about 1.1430.
  • wrenching tools which are adapted for use with threaded members having hexagonal heads are so sized as to accommodate maximum and minimum sized hexagonal headed members such that the maximum ratio of the nominal distance across opposing flats about of such maximum and minimum sized members ranges from about 1.0053 to about 1.0600.
  • such wrenching tools desirably have inner, head-confronting surfaces contoured to provide recesses positioned opposite corners of the fastener heads so as to avoid contact between the tool and the head corners.
  • Visible indicia are carried adjacent each wrench opening, such indicia comprising at least two and preferably three or more specific but different nominal sizes in at least two different sizing systems.
  • a rotary wrenching tool of the invention is provieded with a uniquely configured opening for receiving a polygonal head of a threaded member.
  • the opening may have an axis of rotation and an inner surface comprising a series of spaced arcuate first surfaces concave to the axis of the opening, each such first surface being defined generally as the locus of points falling a given radial distance r from a first axis itself spaced a distance r 1 from, but parallel to, the axis of the opening, and a series of arcuate second surfaces convex to the axis of the opening and spaced about the circumference of the opening, each such second surface being defined generally as the locus points falling a radial distance R from a second axis spaced itself a distance R 1 from, but parallel to, the axis of the opening.
  • each surface that forms a portion of the inner surface and that is contiguous to an arcuate surface preferably tangentially merges into that arcuate surface.
  • the relationship of r and R is such that if r equals R, the wrench includes surface means providing flat surfaces between and tangentially intersecting the first and second surfaces.
  • R 1 desirably is larger than r l , and in the case where each second axis is angularly spaced from at least one next adjacent second axis by 60°, the ratio R 1 /r 1 desirably exceeds 1.5 and preferably exceeds 2.0. In this case also, R is desirably equal to or greater than r, and the ratio R/r preferably exceeds about 5.0. Also in this embodiment in which each second axis is angularly spaced by 60° from at least one next adjacent second axis, the adjacent arcuate surfaces preferably merge tangentially into one another.
  • the second axes of the embodiments described above may, if desired, be spaced from one another by 45° or by 90° to thereby provide an opening accommodating square heads of threaded members.
  • the wrench opening may be provided with a plurality of circumferentially extending surface portions that may intersect at sharp angles, e.g., approximately at right angles, with the inwardly convex arcuate surfaces. Further, inwardly convex arcuate surfaces of different sizes may be interspersed with one another.
  • the rotary wrenching tools of this second embodiment preferably have head-contacting interiors sized to strongly and adequately grip polygonal fastener heads sized in two, preferably three, and up to six different nominal sizes.
  • the ratio (determined as described above) for tools of this secon embodiment accepting square heads ranges from 1.0001 to about 1.1430 and for tools accepting hexagonal heads ranges from 1.0001 to about 1.0600.
  • the wrench opening sizes are varied ( Figures 8, 9, 14, 17, 18, 19, 20, 21)
  • the included angle between adjacent flats preferably is also varied to better accommodate fastener heads sized in different sizing systems.
  • the wrench (10) has wrench flats (11), (12) which are spaced apart a sufficient distance to loosely accommodate the confronting flat surfaces (13), (14) of a hexagonal bolt, shown in phantom lines. If the wrench is turned in the direction of arrow A, it will be understood that the wrench flats bear against the corners of the bolt head, rather than upon the flat surfaces of the bolt head; this is referred to as "corner contact", and use of wrenches of this type can readily score and round the corners of bolt heads, particularly hexagonal bolt heads.
  • the interior surface of the wrench opening makes contact not with the corners of the bolt head but rather at points (actually, lines) along the length of the flat bolt head edges.
  • the rounded lobes (15) of the wrench (16) initially make line contact with the bolt head, but as pressure is applied, the bolt head edges are deformed slightly so that contact between the lobes and the bolt head occurs over a broader surface.
  • such tools are characterized as having uniform interior configuration. That is, similarly configured interior surface elements (e.g., lobes) are radially spaced the same dis - tance from the axis of the wrenching tool opening.
  • similarly configured interior surface elements e.g., lobes
  • the lobes (15) depicted in Figure 7 are equally radially spaced from the axis X.
  • the circumferential surface portions (48) shown in Figure 25 are spaced unequally radially from the axis X, as will be described more fully below.
  • rotary wrenching tools which have no moving parts and which are specifically sized for turning fasteners such as nuts, screws and bolts that have square, hexagonal or other polygonal heads.
  • These wrenching tools are characterized by being capable of strongly and adequately fitting polygonal . heads nominally sized in at least two different systems such as, for example, the American Fractional standard ("AF") and the British Standards (" B S", for example), and of carrying at least two and preferably three or more suitable size markings in different size systems. That is, the rotary wrenching tools of the invention fit polygonal fastener heads such that scoring or rounding of the heads does not occur even when substantial wrenching torque is applied thereto.
  • AF American Fractional standard
  • B S British Standards
  • Such strong and adequate fitting of the tool to the head of the fastener is such that the application of excessive substantial wrenching torque is more apt to cause physical breakage of the fastener head from the threaded stem of the fastener, or simply cause the deformation ("stripping") of the stem threads.
  • those wrenches which have head-confronting surfaces that are contoured to provide recesses opposite corners of the heads to thereby avoid contact with the head corners.
  • the head-confronting surfaces of the rotary tool are provided with inwardly protruding, rounded lobes positioned to encounter the head of a fastening member along flat surfaces of the head, rather than at its corners, the lobe, upon the application of substantial torque, tending to slightly deform the flat surfaces of the head to provide surface-to-surface contact between the wrench and head.
  • the driving heads of bolts and similar fastening members can be sized in the metric system (e.g., mm) and also in inches using American Fractional ("AF") standards (SAE, MIL, etc.) and British standards such as "BS", "BA” and “W” (Whitworth) measurements.
  • the wrenches of this embodiment of the invention are sized so as strongly and adequately accommodate fastener heads of at least two different nominal sizes such that the ratio of the nominal distances across opposing head surfaces falls, in the case of square heads, within the range of about 1.0053 to about 1.1430, and, in the case of hexagonal heads, with the range of about 1.0053 to about 1.0600.
  • Table I set out below provides a non-inclusive, exemplary list of nominal head openings and size combinations for square and hexagonal head fasteners. Referring, for ease of explanation, to the first entry in the table, this entry describes a wrench which will fully and adequately engage the polygonal head of a threaded fastener that has the nominal dimensions of 1.5mm & 1/16 (AF, U.S. standard) & 16 BA (British standard). As shown in the table, 1/16 inches converts to 1.5875 millimeters. 16 BA, in the British standard, corresponds to 1.4224mm. 1.5mm, in the metric system, is, of course, 1.5mm.
  • the maximum ratio of the maximum nominal distance across flats (1.5875) to the minimum nominal distance across flats (1.4224) is 1.1161, and this is recorded in the final column of the table.
  • the last entry in the table refers to a fastener head having a nominal distance across opposing flats of 220mm.
  • the wrench of the invention suitably sized, also fully and adequately fits fastener heads sized in the U.S. American Fractional system as 8 5/8" & 8 3/4".
  • the latter nominal values correspond to 219.0731mm and 222.2481mm, respectively.
  • the maximum ratio of the maximum nominal size to the minimum nominal size hence is 222.2481/219.0731, or 1.0145.
  • the ratios thus referred to are calculated according to the following formula:
  • the rotary wrenching tools of this embodiment of the invention will bear visually readable markings indicating the at least two and preferably three different head sizes for which they were designed.
  • the first wrench appearing in Table I may be marked "1.5 mm & 1/16in. & 16 BA".
  • the table has been computed using international (ISO) and many national standards and specifications from the United States (SAE, ANSI, MIL, ASTM), British (BS), German (DIN), France (FS), Yogoslavia (JUS), Japan (JS) and specifications from various manufacturers in the United States, England, France, Germany, Canada, Japan, Italy, Sweden, Spain, Czechoslavakia, Yugoslavia, Taiwan, China, Brazil, etc.
  • each figure shows positions of a bolt head within the gripping opening of a rotary wrenching tool, the bolt head positions shown in phantom lines referring to the smallest bolt head that can be fully and adequately gripped by the tool.
  • Certain of the Figures also show a wrenching tool in both a socket form (wherein a full circle in either solid or dotted lines appears about the bolt head) or in open-ended wrench form.
  • a socket is shown in dotted lines as (17), the open-ended wrenching tool version being shown in solid lines as (18).
  • the socket embodiment is shown in solid lines as (20) and the open-ended embodiment is shown in phantom lines as (22).
  • alternate positions for the ends of the open-ended embodiments may be varied, and sevetal positions are shown, for example, in Figures 14, 24, 25 and 26.
  • socket and open-end rotary wrenching tools shown generally at (20) and (22) are sized so as to strongly and adequately grip the hexagonal heads of threaded fasteners sized 4 mm & 5/32" & 8 B A, giving a ratio of 1.0363.
  • the wrench of Figure 16 as shown from the drawing, has an axis of rotation X that extends normal to the plane of the paper and has an opening for receiving the polygonal head of a threaded member, in this case, a hexagonal head shown as "H".
  • the opening has an inner, head-confronting surface comprising a series of arcuate first surfaces (24) concave to the axis of the opening and spaced about the circumference of the opening.
  • Each such first surface is defined generally as the locus of points falling a given radial distance r from a first axis "a" that is itself spaced a distance r from, but parallel to, the axis X of the opening.
  • a series of arcuate second surfaces (26) which are convex to the axis of the opening and are spaced about its circumference, each such second arcuate surface being defined general as the locus of points falling a radial distance R from a second axis A which is itself spaced a distance R 1 from, but parallel to, the axis X of the opening.
  • R 1 preferably is larger than r l , and the ratio R 1 /r 1 desirably exceeds 1.5 and preferably exceeds 2.0.
  • Each second axis A is angularly spaced from at least one next adjacent second axis A by 60°.
