Definitions

  • the present invention relates to ceiling coving.
  • the correct method of making a ceiling coving is by the use of plaster, using a purposely designed trowel for the application of the plaster. This method, apart from being time consuming, requires a skilled plasterer.
  • coving may be formed of expanded polystyrene or paper covered plaster.
  • Each of these covings has its attendant disadvantages. In particular, both materials are easily damaged, polystyrene because it dents easily and plaster because it is brittle and its ends are easily scuffed. Storage and transportation present problems as the covings can only be formed in long fixed lengths. Shorter lengths would result in too many joints.
  • the joints between lengths are difficult to disguise when the coving is fixed to a ceiling and furthermore, in the case of polystyrene, the finished appearance leaves a lot to be desired aesthetically because even when painted the mottled texture of the material is in evidence through the paint.
  • the joints also mean that the coving can only be given its finish coating after it has been fixed to the ceiling and if it should need to be painted a different colour from the remainder of the ceiling then painting it becomes both a skilled and a time consuming task.
  • the present invention seeks to provide ceiling coving which mitigates at least some of the above disadvantages present in the prior art.
  • ceiling coving comprising a generally flat, pliable, continuous coving strip, and abutment means for affixing to the wall and ceiling to constrain the coving strip to adopt a curved configuration.
  • a method of securing coving to a ceiling which comprises cutting a desired length of pliable coving from a continuous strip, mounting abutment means on the ceiling and on the adjacent wall, the separation between the abutments on the wall and on the ceiling being less than the width of the coving strip, and pressing the coving strip into the corner between the wall and the ceiling, the abutment means serving to retain the coving strip in position and to constrain the coving strip in the shape of a curved surface.
  • the coving is formed of a flat flexible plastics strip.
  • the strip may itself be decorative, but alternatively the strip may be laminated, being formed of a base layer of polyvinyl chloride (PVC) and a decorative layer of paper.
  • PVC polyvinyl chloride
  • the coving strip may be formed with a pair of hinges extending parallel to its length, the hinges defining two lateral return portions which may be folded back during fixing to contact the surfaces of the wall and the ceiling concealed by the curved portion of the strip, disposed between the hinges.
  • each hinge is formed of a pair of spaced hinge lines, the portion of the strip between the hinge lines protruding at right angles to the wall and ceiling when the coving strip is in position so as to space the curved portion of the coving from the wall and ceiling.
  • the abutment means conveniently comprise brackets affixed between the wall and ceiling at regular intervals. If desired the ends of the brackets may be configured for interlocking engagement with the edges of the coving strip or the return portions of the coving strip.
  • the coving strip may be formed by a variety of known method which need not be described in detail and amongst such methods one can mention extrusion moulding, hot rolling and cold rolling.
  • the brackets may be made by injection moulding or as sheet metal stampings.
  • a pattern may be embossed onto the visible surface of the coving strip and the strip may be supplied pre finished and ready for mounting.
  • the advantage of the coving of the invention is that because it is pliable, it can be supplied in continuous rolls and the limitations imposed by the prior art on the length of any strip of coving are removed. Thus no length need have a joint and consequently there is no reason for not applying a finish coating before mounting the coving on a ceiling.
  • the coving is furthermore held in position only by brackets and it is therefore possible to remove it. This may be desirable during the course of redecoration.
  • the coving may be used to hide wires passed around a room, such as telephone wires. Furthermore, the coving material may itself be translucent permitting a light source to be concealed behind it and giving a pleasing effect when the lights are switched on.
  • corner piece for a convex corner may also be used as an end stop.
  • Figure l depicts a roll l2 of coving strip l0 which is shown more clearly in the section of Figure 2.
  • the strip l0 consists of a plastics base l4 covered with a decorative paper layer l6.
  • the plastics material of the base may conveniently be polyvinyl chloride (PVC) and the adhesive used to secure the paper to the plastics material may be polyvinyl alcohol (PVA).
  • PVC polyvinyl chloride
  • PVA polyvinyl alcohol
  • the plastics base l4 has along each edge two score lines l8 which permit the strip to be bent.
  • brackets 20 are nailed to the corner as shown in Figure 4 with the nails 32 being inserted along a line marked at a given distance from the corner.
  • the brackets 20 are fixed at regular intervals sufficient to hold the coving strip securely.
  • Each bracket 20 is formed of plastics material and comprises an inner section 2l having a central boss 22 with a concave upper surface 24.
  • Two film hinges 26 formed on each side of the inner section 2l connect the inner section to two angled end pieces 28 each formed with a hole 30 for receiving a nail 32.
  • a pip 33 is also formed on the underside of each end piece 28, as viewed in Figure 3, to assist in holding the coving strip against the ceiling or wall.
  • the brackets can be resiliently deflected away from the wall and ceiling sufficiently to permit the folded over edges of the coving strip l0 to be inserted. After slotting in of the edges of the strip l0, the latter is held in position by the pips 32. Double sided adhesive tape 40 is used to secure the coving strip l0 to the central boss 22 of each bracket 20 to maintain the strip in a bowed configuration.
  • the parts of the coving strip disposed between the pairs of hinge lines lie at right angles to the wall or ceiling when the coving is mounted and therefore give an appearance which is the same as that of conventional coving.
  • rolls of paper and plain PVC of the same width are rotatably supported in a jig.
  • a run of material from the PVC roll passes through two rollers which score the surface t o form the hinge lines l8.
  • the run then passes over a glue roller and a doctor blade which together apply a thin layer of PVA adhesive to the underside of the run.
  • the two runs are then brought together in driven pressure rollers and after the adhesive has dried the completed strip is taken up on a roll driven by way of a slipping clutch from the motor driving the pressure rollers.
  • the coving of the invention can, if necessary, be removed. This can considerably simplify redecoration of the room and provide a better finish, since the panels of wallpaper can finish behind the coving and, if a room is painted, the risk of painting the coving strip is avoided. Painting of the coving in a different colour is also considerably simplified.
  • the coving strip may be painted before placing it on the ceiling, and can therefore be purchased ready for use. The task of installation is thus simplified.
  • the strip may be embossed or electroless plated to provide an appearance not achievable with conventional methods.
  • a further and important advantage of the coving of the invention is that the runs of coving have some flexibility, even when curved, and the coving can have a neat appearance even if the walls are slightly convex or concave in places, as is extremely common in practice.
  • the strip may be formed entirely of plastics material and may be formed as an extrusion moulding.
  • the surface of the strip may also be textured or embossed to give more freedom in the design of the coving.
