Definitions

  • the present invention relates to an element for parquet type flooring of the type specified in the preamble of claim 1.
  • Said strips are generally rectangular in shape and have basic dimensions of between 5 cm and 2 m in length and between 1 and 15 cm in width, and a depth or height of between 10 mm and 22 mm.
  • these strips are generally machined along the lateral walls so that they comprise an interlocking groove along two sides and a seat suitable to house said groove along the other two sides.
  • said strips are constrained to the surface below by means of specific cements or adhesives, or alternatively by means of nails or the like.
  • Said wood floorings can be composed of different woods, high quality or not, in particular, oak, olive, walnut, teak, beech, etc.
  • wood floorings are very costly in terms of raw materials and maintenance.
  • Said floorings can in fact be easily ruined through contact with hard bodies, in particular boots, heels, scraping of doors or other elements.
  • scores or chips can form on the exposed surface of parquet type floorings.
  • the replacement operation which can also be carried out for aesthetic purposes, is very onerous, as the single strips must be detached from the adhesive or cement, before repeating the flooring operation.
  • EP 1 514 499 discloses an element according to the preamble of claim 1.
  • the technical aim of the present invention is to devise an element for parquet type flooring capable of substantially overcoming the aforesaid drawbacks.
  • an important object of the invention is to obtain an element for parquet type flooring with reduced maintenance costs.
  • a further object of the invention is to produce an element for parquet type flooring that allows the implementation of a wood flooring that is easy, inexpensive and rapid to replace.
  • a further important object of the invention is to produce an element for parquet type flooring that is inexpensive and that allows the attainment of a surface made of high quality wood.
  • the element for parquet type flooring according to the invention is indicated as a whole with the number 1 .
  • the element 1 when composed as shown in Fig. 1 , the element 1 has a shape similar to conventional strips for parquet flooring.
  • a base portion 2 extending along a prevalent extension plane, and a surface portion 3 made of wood or the like, comprising a homogeneous upper surface 3a suitable to form the external surface of the flooring 10 and releasable constraining means 4 suitable to connect the surface portion 3 to the base portion 2.
  • the base portion 2 is suitable to be constrained to a supporting surface, on which this flooring 10 is positioned, by means of cements, adhesives or nails.
  • Each base portion 2 preferably comprises along two reciprocally adjacent sides a groove suitable to be inserted in a specific seat positioned on the two remaining sides of this base portion 2.
  • the base portions 2 have dimensions along their prevalent extension plane substantially identical to the dimensions used for conventional parquet strips, and on average between 5 cm and 2 m in length and between 1 and 15 cm in width.
  • the height, or depth, of the base portions 2 is instead on average between 5 mm and 15 mm, and appropriately forms a portion of between 1/2 and 9/10, and preferably in the region of 2/3, of the total height or depth of the element 1.
  • the base portions 2 are preferably composed of plywood or another relatively low quality wood, in particular beech. Alternatively, polymer or yet other materials can be used.
  • MDF medium density fibreboard
  • the surface portions 3 are instead preferably composed of a high quality wood, in particular oak, burl, elm, walnut, as they form the external surface of the flooring 10. They can also be composed of an MDF, preferably oak.
  • the surface portions 3 could be produced in imitation wood or the like.
  • the surface portions 3 also extend substantially along a prevalent extension plane and present, along said plane, substantially the same shape, i.e. the same form and the same dimensions, as the base portion 2.
  • Each surface portion 3 comprises a homogeneous upper surface 3a.
  • the upper surfaces 3a will therefore form a flooring 10 having a substantially homogeneous surface interrupted solely by the separation between the single flooring elements 1 .
  • the surface portions 3 have dimensions along their prevalent extension plane 3a substantially identical to the dimensions of the relative base portions.
  • the height, or depth, of the surface portions 3 is instead on average between 2 mm and 10 mm, and preferably in the region of 5 mm, and appropriately forms a portion of between 1/10 and 1/2, and preferably in the region of 1/3 of the total height or depth of the element 1.
  • the element 1 then comprises said releasable constraining means 4 suitable to connect said surface portion to said base portion.
  • Releasable constraining means 4 are composed of a plurality of interlocking elements 4a .
  • Fig. 4 shows in detail, for example, interlocking elements 4a composed of dowels made of polymer material, and in particular polyamide, presenting a cylindrical and knurled external surface.
  • interlocking elements 4a are inserted in specific seats 4b included in the base portion 2 and in the lower part of the surface portion 3, so as not to affect the upper surface 3a of the latter and to allow homogeneity thereof.
  • the seats 4b are composed of circular holes, which are through holes in the base portion 2 and blind holes in the surface portion 3.
  • a plurality of interlocking elements 4a and of seats 4b are preferably provided for each flooring element 1, as shown in Fig. 3 .
  • the interlocking elements 4a can then have different shapes and be of different types and the seats 4b are appropriately countershaped thereto.
  • the releasable constraining means 4 is composed of adhesives, in particular vinyl adhesives, even more in particular by a D3 vinyl adhesive, or by adhesives that remain wet and do not allow the surface portion 3 to be removably constrained to the base portion 2.
  • first intermediate sheet 5 Between the base portion 2 and the surface portion 3 is at least a first intermediate sheet 5 present, having dimensions along the prevalent extension plane substantially identical to the dimensions of said base 2 and surface 3 portions along the same plane.
  • Said first intermediate sheet 5 forms a weak point that produces a detachment surface between the base 2 and surface 3 portions when it is necessary to disassemble them.
  • the first intermediate sheet 5 is preferably composed substantially of cardboard having a grammage of between 200 g/m 2 and 400 g/m 2 .
  • the second intermediate sheet 6 is also preferably composed of cardboard having a grammage of between 200 g/m 2 and 400 g/m 2 .
  • releasable constraining means 4 can also be combined with or used in addition to the adhesive.
  • a plurality of elements 1 is assembled in a conventional manner, i.e. in the same manner as strips forming a conventional parquet type flooring.
  • the assembled elements 1 form a flooring 10 and are fastened to the surface on which the flooring 10 is laid by means of cements, adhesives or nails.
  • the elements 1 can be mounted with the base 2 and surface 3 portions already joined or unjoined.
  • the releasable constraining means 4 can be provided joined to the base portion 2 or to the surface portion 3.
  • the flooring 10 thus forms a parquet which, externally, is of conventional type.
  • the surface of the flooring 10 is damaged, scored or chipped through use or when wishing to change it for aesthetic reasons, only the surface portion 3 and, if necessary, also the releasable constraining means 4, require to be replaced.
  • the invention achieves important advantages.
  • the base elements 2 can be fastened to the lower surface by means of nails, screws or other elements which allow rapid and simple fastening thereof but which are not aesthetically renowned. In fact, these nails and screws are in any case covered by the surface portions 3.
  • the elements 1 are inexpensive, even if they exhibit high quality woods, as only a minor portion thereof is exposed and must be produced in high quality material, while the remaining portion can be produced with inexpensive woods, plywoods or other materials.
