Definitions

  • the present invention relates to a dowel, and the use thereof for holding together panels, slabs or the like.
  • a dowel is a generic word which, according to the Chambers Dictionary, is a "pin for fastening things together by fitting into a hole in each". It is well known to use dowels for the purpose described in its definition. However, dowels come in all shapes and sizes and they are always used in a format which whilst adequately strong for most purposes, are not sufficiently reliable to withstand great shearing forces and hence result in the separation of the two pieces of wood, etc being held together by the dowel.
  • a longitudinally extending dowel having a substantially uniform cross-sectional shape, wherein the shape includes a median waist portion and, tapering outwardly from the waist portion, a pair of wedge members.
  • the wedge members are appropriately shaped portions of the dowel, arranged to fit snugly in a complementary longitudinally extending recess or groove.
  • the wedge members are of substantially the same shapes and sizes (one being a mirror image of the other). However, it is envisaged that the wedge members may be of different dimensions.
  • the dowel has an axis of symmetry about the median waist portion, and/or a plane of symmetry passing through the median waist portion.
  • the dowel may have two or more planes of symmetry passing through the median waist portion.
  • the uniform cross-sectional shape is substantially of an x-shape cross-section, with an axis at the intersection of the two arms of the "x" shape.
  • the wedge members are of substantially dovetail cross-section.
  • the cross-sectional shape corresponds to two triangles having their respective apices in abutment with each other so as to form an hour-glass shape with the axis thereof running through the line of the apices.
  • the cross-sectional shape corresponds to two Y-shape units being joined together through the tails of the Ys such that the line joining the two tails passes through the axis of the dowel.
  • the cross-sectional shape corresponds to a bow-tie shape (in cross-section).
  • external faces of the wedge members are at an obtuse external angle relative to one another, for example in the range from about 175° to about 115°, preferably less than 160°, more preferably less than or equal to about 140°.
  • the dowel can be of any material such as wood, steel or metal, fibre-reinforced polymers, solid rigid polymers such as polypropylene, nylon, or other similar material which has an inherent strength.
  • fibre reinforcement they may be glass fibres, synthetic fibres, natural fibres or the like.
  • the dowel is of plastics, it is formed by extrusion.
  • the dowel may also be either of a solid shape or may be hollow provided that the material of which it is made is sufficiently resilient to enable it to be hammered into position without buckling or being deformed under the force applied to place the dowel in position.
  • the dowel is typically a unitary body.
  • the surface of the dowel may be smooth or rough and the edges thereof may be straight or serrated.
  • a feature of the present invention is that such dowels can be used to hold together two solid materials including inter alia wood, metal, plastics, concrete and the like.
  • the dowels of this invention are suitable for holding together solid materials, such as panels, boards or the like, which are sufficiently soft to enable the dowel to be hammered in but are sufficiently strong to be able to withstand ambient forces of the surroundings where they are used.
  • a recess is provided in each of the respective sides of solid bodies to be held together, the recesses being of such a shape that when the recesses of the two solid bodies are in alignment and ready to be joined together, the cross-sectional shape of the combined elongate opening from the two bodies at the point of the joint between the bodies substantially corresponds to the external cross-sectional surface of the dowel thereby forming a substantially sealing fit with the dowel when the dowel is positioned inside the elongate opening.
  • the recess in each body is shaped to complementarily receive a respective wedge member.
  • the present invention therefore further comprises a kit (typically for assembling panels or the like when the bodies are themselves panels) which comprises a dowel according to the invention and a plurality of bodies adapted to be secured together by means of the dowel, a first one of the bodies including a complementary recess for receiving a first one of the pair of wedge members and a second one of the bodies including a complementary recess for receiving a second one of the pair of wedge members.
  • a kit typically for assembling panels or the like when the bodies are themselves panels
  • a kit typically for assembling panels or the like when the bodies are themselves panels
  • the present invention still further comprises a method of fastening two such bodies using a dowel according to the invention, the first solid body having a first recess corresponding to the shape of the first wedge member and the second solid body having a recess corresponding to the shape of the second wedge member, wherein (i) the first recess is arranged in alignment with the second recess so as to form an elongate opening, and (ii) the dowel is introduced into the elongate opening.
  • the dowel has a cross-section (and an end-face 1) of substantially "bow-tie" shape.
  • the end-face 1 has a median waist portion 2, and a pair of wedge members 3,4 tapering outwardly from the waist portion.
  • the external face 5 of wedge member 3 is at an obtuse angle relative to the external face 6 of wedge member 4.
  • the dowel illustrated is of uniform cross-section along its length 7, and has two, mutually perpendicular planes of symmetry including its longitudinal axis.
  • FIG. 1b to 1f various alternative shapes of dowel according to the invention are shown in cross-sectional view, where the view shown corresponds to the end face 1 of the dowel in Figure 1a.
  • a panel 11 comprises a first board 12 and a second board 13, having sandwiched therebetween a layer 14 of thermally insulating foam.
  • a face panel 15 positioned along the thickness thereof has a timber frame 16.
  • Timber frame 16 has a groove 17 cut therein corresponding in shape to the external shape of dowel 1a.
  • a second groove 19 is cut on an opposing face; this groove corresponds in shape to the external shape of the other half of dowel 1a.
  • An adhesive layer is applied to face panel 15 and the corresponding face panel of the second panel 18, so as to reinforce the bonding between the panel faces.
  • Panels 11 and 18 are then aligned so that the grooves 17 and 19 are in alignment and form a recess corresponding in shape to dowel 1a to be inserted therein.
  • Dowel 1a is cut to the thickness of panel 11 and 18, and inserted into the recess.
