Profiled element for dressing the edge of components, for example made of natural or artificial stone, in building or decoration

Abstract: A profiled element for dressing the edge of a structure (1), for example made of natural or artificial stone in building and decoration, comprising at least one profiled element which is adapted to constitute a dressing edge of said components, said profiled element having a flat rear face for coupling to a substantially vertical arrangement of the component that it must dress, said profiled element being provided with at least one anchoring laminar element (7) for anchoring between the structure (1) and an overlying cladding (2) which protrudes backwards from said flat rear face at a depth (H) from the top of said profiled element which is a least equal to the thickness of said cladding of said structure.

Description: The invention relates to a profiled element for dressing the edge of components a component structure according to the preamble of claim 1. Prior art comprises three types of profiled element for dressing steps or for blending the surface of the sink with the front face of the structure that contains it, particularly in kitchens: a first type constituted by a right-angled profiled element which has a horizontal lip that provides front integration of the tread and riser cladding of the step, which is provided in an upward region with a forward-protruding radiused portion that acts as a dressing edge for said cladding, for example of the "toric" type; a second type constituted only by the riser cladding, which is provided in an upward region with a forward-protruding radiused portion that acts as a tread finishing edge, for example also of the "toric" type; a third type which is similar to the second one but has an internally hollow protrusion to reduce weight. However, all three of the described dressings entail drawbacks. As regards the first type, since it is a right-angled profiled element with the tread lip, the radiused portion, and the riser in a monolithic unit, the unit can be used only for a single tread thickness. The profiled element has manufacturing difficulties and a high cost; however, since it has a tread lip, its installation is stable even in the presence of stronger and more frequent stresses, such as downward stresses. As regards the second and third types, since they do not have the right-angled lip, they face less manufacturing difficulties and provide better flexibility in association with the treads, but since they must be installed by simply gluing their rear face against the vertical riser plane, they do not have the stability which is indispensable to prevent the possibility of becoming loose and to accordingly prevent possible accidents causing harm to people. A nosing arrangement, in accordance with the preamble of claim 1, is known from the document FR-A-2 671 822. This prior art is susceptible of considerable improvements as regards the possibility of avoiding the above-mentioned drawbacks. The above description shows the need to solve the technical problem of providing a profiled element for dressing the edge of components made of natural or artificial stone in building and decoration between a substantially horizontal arrangement and a substantially vertical arrangement which, whilst allowing easy and inexpensive manufacture as well as flexibility in its association with various thicknesses of elements that constitute horizontal and vertical planes, nonetheless allows stability in installation with no risk of failure and consequent harm. The profiled element can be applied for example not only for dressing steps and sink surfaces in the kitchen but also for balconies, window sills, and thresholds, with associated drip moldings and for edge dressing in decoration, including fireplaces. The radiused edge of the profiled element can have a vertical protrusion as well as a longitudinal front protrusion. The invention solves the above-mentioned technical problem by proposing a profiled element according to claim 1. The rear coupling face of said profiled element, which is substantially vertical and flat, has at least one laminar anchoring element which protrudes backwards and is meant to penetrate between the horizontal cladding of the structure and the structure itself, said at least one laminar anchoring element being advantageously constituted by a laminar insert which can be inserted on one side in at least one corresponding slot that penetrates at right angles said rear coupling face if the body of said profiled element is solid or substantially solid; if said body is hollow, for example obtained by extrusion or in any case from thin metal plate, the at least one laminar anchoring element is advantageously monolithic with the profiled element; the anchoring of said at least one laminar element to the profiled element on one side and to said supporting structure on the other side and below said cladding element which constitutes the horizontal plane is facilitated by adhesive or anchoring material in general, such as mortar. The advantages achieved by the present invention are linked to the obtainment of stability upon installation but with very low manufacturing, storage, and transport costs; in particular, the profiled element is or can be provided with a right-angled laminar insert; the vertical position of said insert between the lower face of the cladding element and the upper face of the structure is allowed to vary by varying the thickness of adhesive, mortar, or other material; however, the flat rear face of the profiled element can have a plurality of slots at different levels.
