Definitions

  • the present invention relates to fasteners which are particularly adapted to engage metal members of relatively thin section, such as metal frame members employed in buildings.
  • threaded fasteners are used to secure sheet material to the frame members, as well as securing individual frame members together. Relative to other fastening items such as rivets, threaded fasteners are time consuming to insert. Accordingly in constructing a building, if threaded fasteners are to be employed, the cost of the structure is increased considerably. Still further, threaded fasteners do not lend themselves for use in rapid insertion apparatus such as nail guns.
  • the present invention is directed to a fastener which provides an alternative to known fasteners and is particularly adapted for engagement with metal members cf relatively thin section.
  • the present invention consists in a fastener having an elongated body with at least one sharp leading end and a resiliently compressible gripping portion intermediate the ends of the fastener, the cross sectional area of the fastener adjacent the leading end or ends being smaller than its cross sectional area in at least a part of the gripping portion.
  • Fasteners according to the present invention can be driven through thin section metal members because of their sharp leading end.
  • the fasteners are particularly useful with sheet steel members such as steel wall framing having a thickness of up to 1.5mm, they are, however, also useful for connection to materials of greater thickness including steel up to about 4 mm.
  • the cross sectional area of the fastener in the region of the sharp leading end is however smaller than that of the gripping portion.
  • the fastener is provided with a head at the end of the fastener distal to its leading end.
  • the fastener may not have a head but may be capable of being formed with a head such as by being threaded externally to enable a nut to be screwed onto the fastener.
  • the fastener is in a preferred embodiment substantially tubular and formed up from a sheet of spring steel or a similar material.
  • the tube may be of generally circular, square, triangular or any other suitable cross sectional shape.
  • the fastener has a C-shaped cross section at least in the region of the gripping portion.
  • the natural resilience of the spring steel or like material combined with the C-shaped cross section will provide the gripping portion with its resilience and compressibility.
  • the tube tapers slightly towards the leading end of the fastener and is also chamfered to form a sharp leading end.
  • the fastener has two arms joined either at the leading end or the trailing end of the fastener or both.
  • the arms are resiliently compressible towards one another and form the gripping portion of the fastener.
  • the cross sectional area of the leading end of the fastener or the area between the leading ends of the fastener is smaller than its cross sectional area in the region of the arms which form the gripping portion.
  • the sharp leading end of the fastener may either be formed with a point or a sharp leading edge to assist penetration of the fastener into a substrate while the fasteners according to the present invention are perceived as being particularly suitable for use with thin section metal members they may also be used with other substrates such as plaster board, wood, rubber, plastic and the like. In particular they are useful for connecting such materials to thin section metal members.
  • the fastener should preferably have a hardness, at least in the region of its leading end, of 40 to 54 on the Rockwell C scale. High carbon steels and spring steels provide suitable hardness.
  • a substantially tubular fastener is preferably chamfered off at an included angle of less than 45°, preferably from 12° to 30°.
  • the fastener may be provided with external surface roughening in the region of the gripping portion. This surface roughening preferably comprises a plurality of corrugations extending substantially at right angles to the longitudinal axis of the fastener.

  • the fastener (14) has an elongated metal body (15) which terminates at one end with a sharp leading edge (16) adapted to aid in penetrating the sheet metal members (17) and (18) in Figure 4 and the plasterboard sheet and sheet metal member (20) in Figure 5.
  • the longitudinal axis (21) of the body (15) extends generally through the head (22) of the fastener. However the edge (16) is laterally displaced from the axis (21).
  • the body (15) is of a tubular configuration with a slit (23) in the tube extending the full length of the body (15).
  • a resiliently compressible gripping portion (24) extends generally normal from the head (22) to the face (25) which extends at an acute angle to the head (22) down to the edge (16).
  • the diameter (26) of the tube reduces in a slightly tapering cone down to the leading edge (16), starting at plane (30).
  • Corrugations (27) are formed on the external surface of the gripping portion (24). These corrugations (24) may be located anywhere on the body (15) from the head (22) to plane (30) .
  • fastener (14) may be for many applications two examples of which are shown in Figures 4 and 5.
  • the fastener (14) is driven through sheet metal members (17) and (18) due to the sharp leading edge (16) being displaced laterally from the longitudinal axis (21) which causes the waste material of the hole being formed to be sheared by face (25) leaving a relatively undistorted hole.
  • the fastener (14) of Figure 6 is similar to that of Figure 1 and similar parts will be given the same numeric designation.
  • the fastener (14) may be rolled up from spring steel or high carbon steel strip (32).
  • the strips (32) of Figures 7A and 7B may be parted along the dotted lines (33) and rolled up as shown by the curved arrows (34). In each case the head 22 may be formed before or after the rolling operation.
  • the fasteners of Figures 8 to 17 all involve a pair of arms forming the gripping portion. Similar parts will be given the same numeric designation in the description of these embodiments of the invention.
  • the fastener (40) includes an elongated body (41) bearing a head (42) at one end and a sharp leading end (43) at the other.
  • the body (41) is formed with a gripping portion (44) intermediate its ends.
  • This gripping portion (44) is formed by the body (41) itself and an arm (45) punched out of the body (41) and tapering away from it.
  • Both the body (41) and the arm (45) are provided with transverse corrugations (46) on their external surfaces.
  • two arms (47) and (48) are joined at the sharp leading end (43) of the fastener (40) and are each formed on their outer edges with corrugations (46).
  • the arms (47) and (48) together constitute the resiliently compressible gripping portion (44).
  • Each arm (47) and (48) are joined by a common head (42).
  • Each arm (47) and (48) is formed with a sharp leading end (43) and the arms together constitute the resiliently compressible gripping portion (44).
  • the area defined between the leading ends (43) is smaller than the area defined between the gripping portion (44) such that when the fastener 40 is hammered into a sheet metal member the gripping portion (44) will be resiliently compressed as the arms (47) and
  • the fastener (40) of Figures 14 and 15 is formed of sheet material and again has two arms (47) and (48) joined by a leading end portion (43).
  • Figures 16 and 17 show a further embodiment of a fastener (40) in which the arms (47) and (48) are joined both at the leading end (43) and at the head (42).
  • the arms (47) and (48) are, in use, compressed together upon entering a hole in a sheet metal or other member made by the sharp leading end (43) upon the fastener (40) being driven into the member.
