The edging strip (1) comprises interfitting housing and insert strips (2, 3), the housing strip (2) fitting within the floor surface and presenting an upper edge portion (4) flush with the surface of the floorcovering (18) and the insert strip (3) providing a recessed upper surface to which the underside of the floorcovering edge is fixed, co-operating interlocking means (9, 13 to 15) being provided whereby the insert strip fixedly locates on the housing strip by pressing down along the length of said insert strip. The insert strip (3) has a locking projection along one edge for engaging in a co-operating recess (6) in the housing strip (2) and a resilient tongue (13) along its other edge projecting downwardly for engaging in a further co-operating recess (7) in the housing strip. The tongue has a locking projection (15) for catching behind a co-operating locking projection (9) in said further recess. The invention provides an edging strip which, when used as a divider, provides a smooth transition between divided floor areas and prevents damage to the floorcovering edges.
Description
Improvements relating to Edging Strips for
Floorcoverings
This invention relates to edging strips for floorcoverings whereby said covering can be fixedly located along their edges to an underlying floor surface.
Such edging strips can be used for fixing floorcovering around its edges closely adjacent the walls of a room, or they can be used as dividers between two floor areas having different coverings, eg between a tiled floor and a carpet or vinyl flooring.
A particular disadvantage of known edging strips used as dividers is that they tend to project above the surface of the floorcoverings and, even if they are rounded-off, vehicles passing across the dividers tend to be bumped. In circumstances where the vehicles are intended to carry fragile articles, or hospital patients, this is clearly undesirable. Many arrangements for such edging strips have been proposed in an attempt to provide a smooth transition across the dividers, eg as described in GB-PS 2,147,803, 2,184,351 and 2,187,947.All of these arrangements provide a channel member intended to be located in a groove in the floor surface, which member has at least one sloping wall 1 to provide a support surface for the downturned edge of a flexible covering, such as a carpet or vinyl flooring, said edge thereafter being pressed against the support surface by a clamping strip having a similarly sloping, co-operating edge. Where the two areas both require a flexible covering, e.g. where the same floor covering is to be provided on an access cover and the surrounding floor area, the channel member has both of its walls sloping towards each other and both edges of the clamping strip are similarly sloped. The clamping strip is secured along its length by fixing means, such as countersunk bolts, so that its top surface is in alignment with the surface of the floorcoverings.These proposals are relatively expensive to manufacture, and require appreciable fitting time to prepare the floor groove, align the parts, and bolt them in position.
Furthermore, for safe-handling and to prevent damage, the sloping edge(s) of the clamping strip cannot present a sharp, feather edge, but must be rounded-off. This inevitably results in a small gap being left between the floorcovering where it is turned down and the clamping strip edge in which dirt can accumulate and over which a vehicle can still "bump" and in time, break down the underlying floor surface.
The object of this invention is to provide an alternative arrangement for the edging strip which, when used as a divider, provides a smooth transition between the divided floor areas.
According to this invention, such an edging strip comprises interfitting housing and insert strips, the housing strip being adapted to be fitted within the floor surface and present an upper edge portion flush with the surface of the floorcovering and the insert strip providing a recessed upper surface to which the underside of the floorcovering can be fixed along an edge thereof, co-operating interlocking means being provided on the housing and insert strips whereby the latter can be fixedly located on the housing strip by pressing down along the length of the insert strip.
Preferably, said insert strip has a locking projection along one of its edges for engaging in a co-operating recess in the housing strip and a resilient tongue extends along the insert strip towards its other edge and projects downwardly from said strip for engaging in a further co-operating recess in the housing strip.
Preferably, said tongue has a sloping engagement surface with a locking projection extending therealong for riding over and catching behind a co-operating locking projection in said further recess, the arrangement being such that, for fitting, said insert strip with the edge of the floorcovering attached is angled to enable the locking projection of said one edge of the insert strip to be engaged in its co-operating recess, and said other edge of the insert strip is pressed downwardly to cause the resilient tongue to enter and be locked within its further co-operating recess.
In one embodiment, the said one edge of the insert strip is adjacent said upper edge portion of the housing strip, and said upper edge portion defines the co-operating recess for the locking projection of said one edge.
In another embodiment, the said other edge of the insert strip is adjacent said upper edge portion.
In order that the present invention may be readily understood, and further features made apparent, two basic embodiments and various applications thereof will now be described, by way of example, with reference to the accompanying drawing, in which:
Figure 1A-D are sectional views showing a first embodiment of edging strip,
Figure 2A-D are views similar to Figures A1-D showing a second embodiment of edging strip,
Figures 3, 6 and 7 are sectional views showing three different applications of the first embodiment of edging strip,
Figure 4 is a sectional view of an application corresponding to Figure 3 for the second embodiment of edging strip,
Figure 5 is a fragmentary perspective view of
Figure 4, and
Figure 8 is an enlarged sectional view of an application corresponding to Figure 6 for the second embodiment of edging strip
Referring to Figure 1, the edging strip comprises interfitting, elongate housing and insert strips 2,3 respectively. The insert strips are preferably formed from plastics material such as semi-rigid PVC, or ABS, and housing strips are preferably of metal, eg Aluminium Alloy or Brass. The housing strip 2 is intended to be located within a channel in the floor surface and presents an upper edge portion 4 intended to lie flush with the upper surface of the covering 5 of the floor (see Figure 1 D). The upper edge portion 4 defines a recess 6 in its inwardly facing side wall and a shaped further recess 7 is defined in the upper surface 8 from which the portion t projects, which surface provides a support for the underside of the insert strip 3. The recess 7 has a sloping engagement face 9 having a locking projection 10 extending longitudinally therealong.
The insert strip 3 is basically of shallow, rectangular shape and one edge is provided with a locking projection, or nose 11 and an upper edge portion 12 intended, when fitted, to lie alongside the edge portion 4 of the housing strip, flush with the covering surface 5. Towards the other edge of the insert strip, a resilient tongue 13 projects from the undersurface and is provided with a sloping engagement face 14 and locking projection 15 which are intended to engage and lock against the corresponding engagement face 9 and locking projection 10 of the housing strip. It will be noted that the insert strip provides a recessed upper surface 15 which is intended to be secured to the undersurface of a flexible floor covering to be used therewith, along an edge thereof. It will be appreciated that the depth of this recess will be equal to the thickness of the particular floor covering. The type of plastics for the insert strip will be chosen in dependence upon the particular floor covering material to be used, and the manner in which it is to be attached to said floorcovering, attachment being effected by suitable means eg a suitable adhesive, heat welding, or a combination of both, or gripping devices.
To inters it the strips, the insert strip 3 is angled downwardly toward its said one edge as shown in
Figure 1C to engage the locking nose 11 in its co-operating recess 6 in the housing strip 2 and the other edge of the insert strip is then pressed downwardly whereby the resilient tongue 13 enters its co-operating recess 7 and flexes into the position as shown in Figure 1D in which the co-operating projections 15 and 10 are locked together. It will be noted from
Figure 1 D that the housing strip 2 has a further upper edge portion 16 spaced from portion 4 and that these two portions, together with the upper surface 8, provide a shallow recess in which the insert strip snugly sits when fitted. The floorcovering may be secured along its edge to its respective insert strip 3 either before, or after location of the strip in the housing strip 2.The adhesive or welding attachment of the floorcovering and inserts strip should be waterproof, and to ensure total protection against moisture penetration under the floorcovering, a mastic can be used between the insert and housing strips during fitting.
Referring to Figure 2, this embodimet is essentially similar to the Figure 1 embodiment and like parts are given the same references. Basically the difference is that the locating nose 11 and resilient tongue 13 are reversed on the insert strip 3. Thus, the said other edge of the insert strip lies adjacent the upper edge portion 4 of the housing strip 2 when fitted and the recess 6 for the locking nose 11 is provided in the upper edge portion 16 of said housing strip. This embodiment facilitates unlocking of the interfitting strips 2,3 if for any reason the floorcovering needs to be lifted.
Referring to Figure 3, this shows an application of the first embodiment described above, which divides a hard floor area 17 e.g. ceramic tiles, from a flexible floorcovering 18, e.g. vinyl flooring. It will be noted that the housing strip 2 is rigidly located in the floor surface by anchor lugs 19 spaced along its length.
Figures 4 and 5 show the same application as
Figure 3, but utilizing the second embodiment described above.
Referring to Figure 6, this shows an application of the first embodiment for an access cover and surrounding frame e.g. as described in my GB-PS 2,145,1383. It will be noted that a housing strip 2 is effectively formed integrally around the upper perimeter 20 of the access cover and also in its surrounding frame 21 and that each housing strip 2 co-operates with an insert strip 3 to which a flexible flooring 18 is attached. Therefore, when viewed from above, only the adjacent upper edge portions 4 of the housing strips 2 are visible.
Referring to Figure 7 this shows an application of the first embodiment for a floor movement joint in which elongated frame members 22,23 are spaced from each other by a flexible beam 24. It will be noted that the housing strips 2 are again formed integrally in the upper faces of the members 22,23.
It will be appreciated that the second embodiment described with reference to Figures 2A-D could equally well be used in the applications described with reference to Figures 6 and 7.
Referring to Figure 8 this shows in greater detail the Application described above with reference to
Figure 6 but utilizing the second embodiment of edging strip with minor modifications. Thus, it will be noted that, the locking projection 11 of each insert strip 3, instead of having a stepped nose has a slanted face which fits against a mating slanting edge undercut from the upper edge portion 16 of its respective housing strip 2. Furthermore, each insert strip 3 has a further resilient tongue 24 which is oppositely arranged with respect to the tongue 13 as shown and the two tongues snap fit between a pair of opposed ribs 25, 26 provided in the upper faces of profile frame sections 20, 21 (which are preferably of aluminium as described in my
GB-PS 2,145,138 B) for the access cover and surrounding frame respectively.The rib 26 is formed on an insert piece 27 fixed to each profile section 20, 21. It will be appreciated that such an opposed tongue arrangement enables a tighter fit to be achieved for retaining the insert strip in position. In this embodiment, a holding down bolt arrangement 28 for the access cover is shown. In this arrangement the head 29 of the bolt 30 passes through an aperture in the cover defined by a clamping ferrule 31 for clamping the surrounding floor covering 18 and the bolt is screwed into a threaded socket 32 provided in the mouth 33 of the access opening. The ferrule 31 holds down the floor covering onto a cover decking plate 34 from the inside by an externally threaded bush 35 which additionally has an internal thread 36. In this way, when the bolt 30 is removed, a lifting key (not shown) can be screwed into the thread 36 of bush 35 for lifting the access cover.
It will be appreciated that a number of such holding down bolts can be provided around the access cover as required.
