DESCRIPTION:
BRIEF SUMMARY
This invention relates to edging strips for floorcoverings whereby said coverings can be fixedly located along their edges to an underlying floor surface and is a development of the invention described and claimed in co-pending patent application No. 9124660.3 Ser. No. 2250192.
Floor 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, e.g. between a tiled floor and a carpet or vinyl flooring.
A particular disadvantage of known edging strips is that they tend to protect above the surface of the floorcoverings and, even if they are rounded-off, vehicles passing across the strips tend to be bumped. In circumstances where the vehicles are intended to carry fragile articles, or hospital patients, this is clearly undesirable. Furthermore, repeated Dumping causes the floorcovering to be damaged or broken down.
In said co-pending Patent Application there is described a method of securing an edge of a floorcovering fitted to an underlying floor surface which is characterised by providing an elongate edging strip comprising a housing strip and an insert strip which are interfitted together via co-operating locking means formed on said strips, selecting the material of said insert strip to be of a plastics which will readily bond with the underside of the floorcovering, fixing said edging strip along said floor surface to define a line along which said edge of said floorcovering is to extend so that said housing and insert strips present respective upstanding edges which extend parallel and adjacent each other along said line flush with the surface of the floorcovering when fitted and the insert further presenting a support surface for said edge of the floorcovering, cutting the floorcovering to present an edge which overlies the support surface of the insert strip and abuts said upstanding edge of the insert strip, and bonding the underside of said floorcovering along said edge to said surface and upstanding edge of the insert strip. Said Application also describes preferred embodiments of edging strips adapted to the method. In these preferred embodiments, the interlocking means generally comprises a locking projection extending along one edge of the insert strip for engaging in a co-operating end recess in the housing strip and at least one tongue extending along the other edge of the insert strip which projects downwardly from said strip to engage in a further co-operating recess in the bottom of the housing strip.
Whilst such embodiments have prooved successful in use, the depth of the housing strip needs to be significant to enable the further recess to be accommodated in the bottom of the housing strip. Because of this the floor area to be covered needs to have channels dug out to accommodate the housing strips.
An object of the present invention is to provide an edging strip in which the housing strip can be of shallower depth.
According to the present invention an edging strip for securing floorcovering along an edge thereof to an underlying surface and comprising a pair of elongate housing and insert strips which are adapted to interfit with each other, the housing strip having an upstanding edge which extends to be flush with the surface of the floorcovering when fitted, and the insert strip being of a plastics material to which the underside of the floorcovering can be readily bonded, said insert strip presenting a surface for supporting the underside of the floorcovering along an edge thereof and an upstanding edge which extends to be flush with the surface of the floorcovering when fitted and against which the floorcovering edge abuts, and co-operating interlocking means provided on respective housing and insert strips whereby the insert strip can be fixedly located on the housing strip, is characterised in that said co-operating interlocking means comprise the housing strip being of generally U-shaped cross section, one side wall of which is higher than the other sid
