Definitions

  • the present invention is concerned with joint sealing devices, such as are used to close and seal the generally linear gaps which are formed during the construction of walls, floors and ceilings as well as the installation of construction elements such as window frames and panels.
  • Such gaps include expansion joints which are formed to accommodate expansion and contraction occurring between adjacent components.
  • the gaps with which the invention is concerned may extend vertically, horizontally or at intermediate angles.
  • a joint sealing device comprising two elongate components, each of generally uniform cross-section throughout its length, the first said component comprising, in cross-section, two parts interconnected by a linear hinge to enable them to fold towards each other, the mutually remote faces of those parts being at least partially covered by a resilient material, and the second said component being adapted for insertion between said parts to urge them apart and further being adapted to engage and be retained by locking means upon said first component.
  • the first component of the joint sealing device of a size selected to reflect the gap size, is inserted in a folded condition into the gap and the second component is inserted progressively between the two parts of the first component until the desired seal is formed and the second component has been locked within the first component.
  • the two components of the joint sealing device according to the invention are preferably and most conveniently formed by extrusion. They may be made of a plastics material or of metal and may be made each of the same material or of different materials, for example the first component of plastics material and the second component of metal. Suitable materials include polyvinyl chloride, polyethylene, polypropylene, nylon, aluminium, brass, steel and combinations of these materials.
  • the two parts of the first component are preferably, but not necessarily, mirror images in cross-section.
  • the hinge is most preferably an integral hinge, formed during extrusion of the first component.
  • the second component of the joint sealing device is preferably of a tapered cross-section, for example generally triangular in cross-section, so that it may more effectively urge apart the two parts of the first component progressively as it is inserted between them.
  • the second component may be of solid or hollow cross-section.
  • the locking means by which the two components are retained in interengagement most preferably takes the form of one or more linear projections or sockets on the surface of one component adapted to engage one or more corresponding linear sockets or projections on the facing surface of the other component.
  • the projection(s) and socket(s) are so shaped as to make subsequent withdrawal of the second component difficult or effectively impossible.
  • Most preferably more than one projection or socket is provided on at least one of the components, and preferably upon both of them, so that the components may interengage progressively in a ratchet-type locking fashion.
  • the external or rear faces of the first component that is the outer faces of its two parts when it is folded, are at least partially covered by a resilient material.
  • the resilient material covers at least a major part of those faces and it is particularly advantageous if the resilient material also covers the hinge, so that the material may act to tend to unfold the component in use.
  • the resilient material is preferably a foamed plastics material, among which materials may specifically be mentioned open-cell or closed-cell polyvinyl chloride, polyethylene, polypropylene, polyurethane and poly (ethylene vinyl acetate), according to the quality of the seal required.
  • the resilient material has, on its face remote from the joint sealing component, a high-friction surface or a layer of adhesive, to prevent or minimise any movement of the device relative to the joint surface.
  • a front face of the second component When the joint sealing device has been installed, a front face of the second component will normally remain visible. It is therefore particularly desirable that that face be extended, laterally of its length, so as to project beyond the edges of the joint. In this way, not only may the joint be very effectively sealed against the incursion of extraneous materials but also the appearance of the joint may thereby be enhanced. To that latter end, the front face of the second component may be given a decorative finish, which may if desired match or complement the surroundings of the joint.
  • the outermost edges of the first component of the joint sealing device may be extended laterally as aforesaid and the respective front faces of the two components may cooperate to provide a finish for the joint.
  • the two components may be formed in continuous lengths by extrusion. For practical reasons, they are preferably cut to manageable lengths, for example within the range from 2 to 4 metres, before installation. When the device is being installed, it is preferred that the two components be staggered lengthwise, such that the joints between adjacent lengths of the first component do not coincide with those of the second component.
  • the lateral dimensions of the two components are selected to reflect the dimensions of the joint. Typically gaps within the range from 5 to 100 mm and larger may be sealed by the device according to the present invention.
  • the illustrated first component 20 comprises a continuous extruded length 21 of the selected plastics material, formed with a continuous lengthwise hinge 22 to enable it to fold in two parts 23, 24.
  • the component has, bonded to the rear face of the material 21, a resilient foam 25, which extends across the parts 23, 24 and over the hinge 22. The foam tends to urge the component towards an unfolded condition.
  • the second component 26 is extruded to form a hollow triangular section with an integral flat front face 27.
  • the inner face of the first component 20 when folded and the cooperating inclined faces of the second component 26 are provided with linear serrations 28 and grooves 29 so that, when the serrations and grooves are fully engaged as shown in Fig. 3, the two components cannot readily be separated.
  • the parts 23, 24 of the first component are urged apart and tend to compress the foam 25 against the walls 30, 31 of a gap within which the device is located.
  • the foam further assists in sealing the gap, which is closed off by the front face 27 of the second component.
  • the foam exerts a constant outward pressure to maintain the integrity of the seal during any movement of the walls of the joint.
  • Fig 4 illustrates a variant form of the device of Figs. 1 to 3 in which the angle at the apex of the second component 32 is smaller than that of the component 26 of Figs. 1 to 3. Because the inclined faces of the component 32 are therefore steeper, a greater area of contact and compression is established between the device and the walls of the joint gap.
  • the front face 33 of the component 32 is curved to enhance its appearance and the protection afforded by it.
  • Figs. 5 and 6 respectively are devised to provide a seal for a recessed joint.
  • the front face, 34 or 35, of the second component is modified, either to seal the gap at its outermost point as shown in Fig. 5 or to fit securely within the gap in the manner illustrated in Fig. 6.
  • Fig. 7 illustrates a form of the joint sealing device of the present invention which is specifically adapted for fitting to seal a gap between joint walls 36 and 37 meeting to form a corner.
  • one edge 38 of the front face 39 of the second component 40 has been formed in a flexible material co-extruded with the component 40 and functions as a sealing gasket against the wall 37.
  • the outer edges of the first component 41 are extended laterally in the form of lips 42, 43, which engage the wall 44 at each side of the gap in which the device is located and retain the component 41 in position.
  • the front face 45 of the second component 46 is designed to fit flush with the front of the retaining lips.
  • Figs. 9 and 10 show two forms of the invention devised to seal smaller joint gaps.
  • the second component in each case is extruded as a solid section, rather than hollow as in the other embodiments of the invention.
  • the components 47 and 48 are provided on each side with just two serrations 49 and mating grooves.
  • the first face 50 of the second component 48 forms the cover for the gap.
  • the components 51 and 52 are locked together by a single serration 53 and groove on each side.
  • the edges of the first component 51 are extruded laterally to cover the gap and the front faces of the two components are flush.
  • the joint sealing devices according to the invention afford an effective way of sealing joints in a wide variety of situations.
  • the devices are easily installed and are held in place by their own pressure and can accommodate a degree of movement within the joint when in use.
