Definitions

  • a hammer is provided with a glass fiber reinforced handle having a tenon'shaped end portion in pressuretight engagement with the eye of the hammer head.
  • the handle which is securely connected to the hammer head without the necessity for separate wedging members or materials, is spaced from the head at the inner end of the eye while being in intimate surface contact therewith along the plane of percussion for a distance of approximately two-thirds the axial length of the eye.
  • the shank and grip portions of the glass fiber reinforced handle are dimensioned to permit mounting of the handle by passing the shank and handle portions through the eye.
  • the handle is self-aligning within the eye by means of a pair of opposed handle aligning ribs which also serve to confine an auxiliary bonding material.
  • Thisinvention relates generally to handtools. More particularly it is directed to a new and improved connection between the handle and head of hammers and similar handtools.
  • Such wooden handles generally are provided with a gripping portion of comfortable hand size which usually exhibits an enlarged cross section relative to the eye of the tool head.
  • the handles are conventionally inserted into the outwardly tapered eye of a tool head from the inner end thereof.
  • the handles are then secured within the eye by means of one or more wedges driven into the handle from the eyes outer end. Thereby, the wedge or wedges cause the handle to expand within the eye into interfering locking engagement with the diverging walls of the eye.
  • the present invention has as an object the provision for a new and improved handtool of the type described which includes a firm, secure handle connection of prolonged operating life, the connection obviating the nccessb ty for separate wedging members or material and eliminating many of the deficiencies heretofore associated therewith while at the same time retaining the advantageous features thereof.
  • Another object of the present invention is to provide a new and improved handtool wherein the forces acting on the tool head upon percussive use thereof are selectively dissipated duringtransmission thereof to the tool handle thereby reducing the required dampening of shock transmission within the handle.
  • An additional object of the present invention is to provide a new and improved handtool of the type described which not only facilitates a lower shock transmission to the handle despite intimate contact with the tool head, but also facilitates the utilization of handles exhibiting improved dimensional stability under ambient conditions and greater tensile strength and resistance to compression.
  • Still another object of the present invention is to provide a new and improved handtool having a connection between the handle and the tool head which is devoid of separate wedging members and permits the use of fiber reinforced handles while substantially eliminating abrasive edge contact between the head and the handle and reducing potential areas of high stress concentration, thereby substantially obviating the undesirable fraying, splitting and delamination evidenced heretofore.
  • a further object of the present invention is to provide a small handtool of the type described which includes a handle having a self-locking tapered connection with the tool head, the connection including intimate'contact between the handle and the head at the axis of percussion of the tool head and positive spacing therebetween permitting limiting oscillation of the tool head.
  • a further object of the present invention is to provide a new and improved tool handle of light yet durable construction and of sufficient resilience to absorb shocks and jars incident to its use, yet being readily insertable and self-aligning within the eye of the tool head during assembly and providing a pressuretight self-locking connection therewith when assembled even in the absence of additional bonding means; the handle further providing positive interference to centrifugal and momentum forces to which the tool head is subjected during use while obviating points of stress concentration within the handle despite the leverage strains to which the tool is subjected.
  • Still another object of the present invention is to provide a handtool of the type described having a handle which extends through the full length of the eye and provides intimate contact with the surfaces of the eye at the curved outer end thereof to provide the back of the tool head with a smooth, flush surface which minimizes the concentration of forces and prevents formation of indentations or marks on finished work when using the tool for pulling nails or the like.
  • a tool handle with a flared or tenon head portion which fits within the eye of the tool head so as to provide full surface contact along the front and rear walls of the eye within the environs of the axis of percussion while at the same time providing a gap or space between the handle and the tool head at the inner or handle end of the eye.
  • This construction facilitates the assembly of the handle on the head by passing the full length of the handle through the eye from the back of the tool head,
  • connection is particularly well suited for use with fiber reinforced handles and provides for both alignment during assembly and auxiliary bonding between the sides of the handle and the sidewalls of the eye.
  • FIG. 1 is a fragmented side view, partially broken away, of a hammer incorporating the features of the present invention.
  • FIG. 2 is a fragmentary sectional view taken along the lines 2-2 of FIG. 1.
  • a claw hammer generally designated by the numeral 10, which is constructed in accordance with the present invention to provide a secure pressure-tight connection between a hammer head 12 and a handle 14.
  • the particular hammer head 12 used to illustrate the present invention is provided with a conventional poll and bell I6 and bifurcated claw 18 separated by a central portion 20 having a downwardly projecting shank or boss 22.
  • the usual eye 24 of the hammer head extends through the central portion 20 and shank 22 along an axis generally perpendicular to the medial axis 26 of the poll and bell which, for the purpose of discussion, can be considered to be substantially coincident with the axis of percussion of the hammer head 12.
  • the eye 24 is of generally rectangular cross-sectional configuration and extends from its inner or handle end within the shank 22,
  • the eye 24 converges or tapers inwardly from its outer end along a major portion of its length and then progresses in a generally unchanging manner through shank 22.
  • front and rear eye wall portions 32, 34 respectively, converge inwardly from the back 28 of the hammer head to provide an eye opening of mortise eonfiguration.
  • the sidewall portions 36 of the eye also taper slightly along the same axial distance but the taper is negligible relative to that defined by wall portions 32, 34.
  • the inner or handle end portion of the eye within the shank 22 is not tapered in the same manner and, as in the embodiment illustrated, may have no taper whatsoever.
  • the tool handle 14 is preferably formed of a fiber reinforced material.
  • the handle 14 is an elongated member of generally rectangular cross section and includes a rodlike grip end portion 40 shown as having an elliptical sectional configuration which is joined to a tenon-shaped head portion 42 by an integral shank portion 44 extending forwardly from the grip portion 40 toward the hammer head.
  • the shank portion 44 is slightly enlarged relative to the grip end portion 40 and includes substantially flat top and bottom surfaces 48, 50 which start to gradually taper in a diverging manner about midway along the shank until they reach the head portion 42 located within the eye of the tool head.
  • the convex sidewalls 52 of the shank portion gradually assume a substantially flat configuration thereby smoothly blending into the flat sided, generally rectangular configuration of the head portion 42 and providing a cantilever beam construction at the important grip end of the eye.
  • the width and depth of the handle throughout the grip and shank portions are substantially smaller than the eye 24 and are configured so as to readily pass through the eye of the hammer head from the outer end thereofwithout substantial interference.
  • the surfaces 56, 58 define a self-locking included angle equal to or, slightly larger than the angle defined by the front and rear walls of the eye thereby assuring tight intimate contact between the head and the handle at the area of intersection by the axis of percussion 26 after pressure mounting of the handle on the head.
  • This self-locking taper provided on the head 42 of the handle is preferably an included wedging angle of between about 8 and 12. In this regard it has been found that an angle of less than 8 results in undesirable variations in the ultimate handle length due to manufacturing tolerances of the eye while handle tapers greater than 12 may not be adequate to prevent disassembly under certain conditions of extreme use. Accordingly, in practice an included angle of approximately 9 is preferred for the handle head.
  • the taper defined by the front and rear walls of the eye may coincide with the taper of head portion 42 of the handle.
  • the angle defined by these walls be slightly less than the angle of the head portion of the handle, i.e., about 8-9, so that as the handle 14 is assembled therein under pressures of about 3 tons, a firm and secure locking engagement is provided between the handle and the walls of the eye.
  • the contact is along only a limited length of the eye, the shank 22 being spaced from the handle at its free end to permit limited oscillation of the head relative to the handle.
  • the connection enables the utilization of handle materials which do not possess the full damping characteristics of wood while the taper and tight pressure fit provide locking interference to the centrifugal forces acting on the hammer head during use.
  • the head portion 42 of the handle is preferably of lesser width than the eye along a major portion of its length but is enlarged at 72 adjacent its free end to provide a snug fit with the hammer head about the outer perimeter of the eye.
  • the present invention provides a handle connection which completely fills the outer end of the eye and exhibits a smooth, flush and continuous back surface on the head of the hammer thereby preventing undesirable indentation of the finished work product when the hammer is used to pull nails.
  • ribs 74 Spaced from the enlarged end portion 72 of the handle head toward the inner end of the eye and enclosed by the sidewalls of the shank 22 are a pair of transversely extending ribs 74 integral with and protruding from the sidewalls of the handle head.
  • the ribs 74 are of sufficient thickness to contact the sidewalls of the eye upon insertion of the handle head therein and maintain the handle in full alignment until it is firmly secured within the eye.
  • the ribs 74 in conjunction with the enlarged end portion 72 define a pair of side recesses which extend across substantially the full transverse dimension of the eye.
  • the recesses defined by the side ofthe hammer head and eye are well suited for receiving a suitable bonding material, such as an epoxy resin, ifsuch is deemed desirable.
  • the bonding material serves primarily to assist in retaining the handle within the eye of the hammer head.
  • the ribs 74 facilitate not only the alignment of the handle within the hammer head during initial assembly and prior to pressure locking therein but also enable utilization of an auxiliary bonding material, such as epoxy, to be inserted within cavities located on each side of the handle.
  • a small locating bead 76 is provided on enlarged portion 72 at its inner end, the bead extending about three sides of the handle head 42 and being substantially sheared off or flattened upon pressure attachment of the handle to the tool head.
  • the ribs 74 permit the positive space 66 between the shank 22 and the handle to completely circumscribe the handle at the inner end of the eye. It will, of course, be appreciated that a minor amount of the adhesive material may unavoidably flow into a portion of the space 66 between the shank 22 and the handle without substantially interfering with the advantages of the present invention. Additionally, aesthetic considerations may require that the space 66 be filled with a resilient material such as a silicone resin or that a sleeve be provided to cover the open end of the space without interfering with the improved functioning of the connection.
  • the preferred handle material for use in the assembly of the present invention is molded fiber reinforced plastic.
  • Such material is less susceptible than wood to dimensional variations under differing ambient humidity conditions and exhibits higher tensile strength and greater resistance to compressive forces than the heretofore conventionally employed wooden handles.
  • Typical of the materials which have proven most effective are the glass fiber reinforced polyesters.
  • nonwoven filaments of fiber glass extend continuously from the grip end 40 of the handle to the head portion 42 thereof and constitute approximately 60 percent by weight (about 40 percent through 45 percent by volume) of the handle.
  • the continuous filaments or strands have an average diameter of approximately three-tenths mils and are embedded within and encompassed by the resin.
  • the fibers will be positioned adjacent the exterior surface of the handle and enhance the tensile strength of the handle.
  • a compression molding technique has been found to provide the desired structural integrity and aesthetically pleasing appearance for such handles.
  • the fibers will form a greater part of the cross section of the grip end of the handle and fillers may advantageously be added to the handle head to enhance the shock absorption characteristics thereof.
  • the grip portion 40 thereof is provided with a circumscribing sheath or grip 78, preferably formed of rubber or like material, which is permanently bonded to the handle by a suitable adhesive.
  • the outer surface of the circumscribing grip tapers inwardly to merge into the contour of the handle at the point of juncture 80 between the grip and shank portions thereof, the juncture 80 providing a smooth arcuate connection between the two portions thereby avoiding undesirable sharp edges within the fiber reinforced handle.
  • the circumscribing grip 78 is attached to the handle after the handle has been mounted within the eye 24 of the hammer head.
  • the handle is mounted by passing the grip and shank portions thereof through the eye 24 and bringing the tapered surfaces on the handle and head into confronting relationship, the head portion of the handle having previously been treated, such as by roller coating, with a suitable auxiliary bonding material.
  • the head portion 42 of the handle smoothly slides into the eye and is held in a fully aligned condition by the ribs 74 and the enlarged free end portion of the handle head.
  • the handle is driven further into the eye under a pressure of about 3 tons to bring the front and rear walls 32, 34 of the eye into compressive engagement with bottom and top surfaces of the handle head thereby securely locking the handle within the hammer head.
  • an epoxy may be used to assist in the secure fastening of the handle within the eye of the hammer head, it will be readily appreciated that the use of such an auxiliary adhesive material is an optional feature of the present invention since the locking taper on the handle head suitable interlocks the handle in the eye of the hammer head.
  • the improved connection of the present invention between the tool handle and the head provides intimate surface contact substantially centered on the axis of percussion for the tool while limiting this contact to a distance approximately equal to twothirds the axial length of the eye of the tool head. It positively provides spaced. relationship between the handle and tool head adjacent the inner end of the eye and prevents sharp edge contact which might otherwise adversely affect tool handles made of fiber reinforced materials.
  • Such a connection not only directly transmits the principal percussive forces acting on the hammer head during use but, in limiting the area of direct force transmission, also permits limited vibratory oscillations.
  • This wedge-free construction not only enables the utilization of materials having greater dimensional stability than the conventional wooden handles but at the same time provides positive interference to disconnection through the tapered self-locking configuration of the handle head,
  • This construction of the present invention additionally permits self-alignment of the handle within the eye of the tool head prior to the formation of a secure locking connection therebetween and enables the use of supplemental bonding materials.
  • a tool comprising a tool head having a work performing portion and an elongated handle receiving aperture, and a handle positioned within said aperture and extending outwardly from one end thereof, said handle having a pair of elongated opposed surfaces disposed within the aperture and facing generally toward and away from the work performing portion of the tool head, said opposed surfaces being in secure contact with the tool head along a major portion of their extent to provide a tight fit between the handle and the head and being spaced from the head immediately adjacent the end of the aperture from which the handle extends.
  • the tool head is provided with an axis passing through the aperture and the work performing portion, the aperture including an eye open at both ends and extending through the tool head at substantially a right angle to said axis, the handle being positioned within the eye along its entire length and terminating at one end thereof, said eye having opposed walls facing generally toward and away from the work performing portion of the tool head in confronting relationship to the opposed handle surfaces, said confronting walls and surfaces being in spaced relationship adjacent the end of the eye from which the handle extends and being in secure interengagement from adjacent the terminal end of the handle through their points of intersection with the axis of the tool head.
  • the tool of claim 1 wherein the handle is a fiber reinforced member having elongated nonwoven fibers extending therethrough.
  • a percussive hand tool consisting essentially of a tool head and a fibre reinforced handle connection to the tool head, said tool head having an aperture therein, said fiber reinforced handle being positioned within said aperture in pressure-tight intimate contact with the head to provide the connection therebetween.
  • said tool head having a plane of percussion passing directly through the fiber reinforced handle substantially centered on the area of pressure-tight intimate contact with the head, the handle having elongated nonwoven fibers extending therethrough; the fibers within the handle being predominantly continuous filaments extending substantially the entire length of the handle and into the aperture, said filaments within the aperture being spaced from the tool head at their point of entrance into the aperture to prevent fracture thereof upon use of the tool.
  • the hand tool of claim 10 including side cavities between the handle and the head substantially parallel to the plane of percussion, and an adhesive within the cavities to assist the maintenance of the pressure-tight intimate contact between the fiber reinforced handle and the tool head.
