DESCRIPTION:
BRIEF SUMMARY
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 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 edg
