Definitions

  • the present invention relates to a parquet, the relative assembly and disassembly kit and the relative assembly and disassembly method.
  • parquets comprise a plurality of adjacent strips which are laid on the floor along respective edges.
  • Two consecutive strips are usually coupled and associated with each other according to a shape coupling, conventionally of the male/female type, so as to create an interlocking fixed structure.
  • This type of coupling has the advantage of being very practical and fast, since the various strips are placed adjacent and quickly interlocked to each other, to form the parquet as a whole.
  • the disassembly of the parquet may be caused by various factors; conventionally, it may be necessary to replace some strips since they are damaged, stained or deformed/warped due to infiltration of water or liquids.
  • the disassembly of the strips is an irreversible operation, since it is necessary to break or, in any case, partially damage at least one strip so as to extract it from the laying plane. Once a strip has been extracted, it is then possible to remove the others.
  • two adjacent strips are usually irreversibly damaged so as to proceed with the partial removal of the parquet. Irreversible damage to one or more strips is an unpleasant event which must be avoided as much as possible since it leads to an increase in the maintenance/replacement costs of the parquet. Solutions according to the preamble of claim 1 are disclosed by WO 2006/043893 A1 .
  • reference number 4 globally indicates a parquet comprising at least one first strip 8 and one second strip 12, each having a body 16 extending along a prevailing longitudinal direction L-L.
  • the body 16 identifies a pair of bases 20 for the laying thereof.
  • the body 16 has a rectangular section with respect to a section plane perpendicular to said prevailing longitudinal direction L-L.
  • the bases 20 also constitute the bases of said rectangular section and are connected by lateral edges 24.
  • Said body 16 is provided, at at least one lateral edge 24, with a seat or perimeter recess 28 recessed with respect to said lateral edge 24.
  • the body 16 is symmetrical with respect to a midplane M-M parallel to said prevailing longitudinal direction L-L, therefore it provides a seat or perimeter recess 28 at each lateral edge 24.
  • Joint 32 means an interstice parallel to said prevailing longitudinal direction L-L.
  • the parquet 4 comprises at least one connection element 36 housed in the seats or perimeter recesses 28 of said first and second adjacent strips 8, 12.
  • connection element 36 is deformable from a non-deformed or rest configuration, in which it is housed at least partially continuously in the seats 28 of said first strip 8 and second strip 12 so as to create an undercut to a relative vertical movement between said strips 8, 12, along a vertical direction Z-Z perpendicular to the prevailing longitudinal direction L-L and to said bases 20, to a deformed configuration in which the connection element 36 is housed in only one of said seats 28 or has a discontinuity or separation 40 at said joint 32 so as to allow the separation of said strips 8, 12 in the vertical direction Z-Z.
  • connection element 36 seamlessly, therefore continuously, extends between the seat 28 of the first strip 8 and the seat 28 of the second strip 12, so as to create an undercut at the separation between the strips 8, 12 according to a vertical separation direction Z-Z.
  • the discontinuity or separation 40 is simply a fracture between two portions of the connection element 36, aligned along the joint 32, so as to allow the separation of the two parts of the connection element, each housed in the seat 28 of a relative strip 8,12, so as to separate said strips 8,12 from each other along the vertical direction Z-Z.
  • connection element 36 has an arch shape, in the non-deformed configuration.
  • connection element 36 extends between a pair of ends 44 shaped to block the connection element inside the seat 28 so as to counteract the sliding of the connection element along said longitudinal direction L-L. In this manner, the connection element is prevented from accidentally or unintentionally sliding in the longitudinal direction in the seat 28.
  • said ends 44 are pointed flared. In this manner, the blocking of the longitudinal sliding of the connection element 36 inside the seat 28 is increased.
  • said ends 44 are provided with a rough surface. In this manner, the blocking of the longitudinal sliding of the connection element 36 inside the seat 28 is increased.
  • connection element 36 has at least one flaring 48 in a vertical direction Z-Z, facing the respective joint 32.
  • connection element 36 may be made of various materials.
  • the connection element 36 is made of wood or metal.
  • connection element 36 has a vertical thickness 52 equal to a vertical height 56 of said seat or perimeter recess 28.
  • connection element 36 may be an elastically deformable connection element so that it may elastically, i.e., in a reversible manner, switch from the non-deformed configuration to the deformed configuration and vice versa. In this manner, the connection element 36 may be repeatedly reused, without need for replacement.
  • connection element 36 in said deformed configuration the connection element 36 is elastically deformed so as to be housed inside a single seat 28 of one of said adjacent strips 8,12 and allow the separation of said strips 8,12 in the vertical direction Z-Z, since the undercut effect is lacking.
  • the same connection element 36 returns to the non-deformed configuration so as to exercise the undercut blocking between the strips 8, 12 along the vertical direction Z-Z.
  • connection element 36 is a plastically deformable connection element so as to irreversibly switch from the non-deformed configuration to the deformed configuration in which it is permanently housed inside a single seat 28 of one of said adjacent strips 8,12 or is interrupted at said joint 32, to allow the separation of said strips 8,12 in the vertical direction Z-Z.
  • connection element in the plastically deformed configuration may permanently deform so as to press itself inside a single seat 28, or it may fracture at the height of the joint 32 so as to allow the separation between the strips in the vertical direction Z-Z.
  • connection element 36 has at least one notch 60 at said joint 32 so as to facilitate the breaking thereof at the joint 32 itself.
  • the present invention also relates to a parquet assembly and disassembly kit 4 as described above.
  • said kit comprises at least one disassembly tool 64 comprising a gripping portion or handle 68 and a foil 72 configured to pass through the joint 32 and to vertically and longitudinally slide along said joint 32.
  • said foil 72 is shaped so as to deform the connection element 36 from the non-deformed configuration to the deformed configuration.
  • the foil 72 is shaped so as to flatten and keep flat the connection element 36 inside one of said seats 28, sliding in the joint 32, parallel to said longitudinal direction L-L.
  • the foil 72 is, according to an embodiment, shaped so as to penetrate into the joint 32 and break the connection element at at least one notch 60 made at said joint.
  • said foil is preferably a metal foil.
  • connection element 36 comprises at least one gap or step 76, preferably arranged on a convex side 80 of the connection element 36.
  • the disassembly tool 64 after having been correctly inserted into the joint 32 between two adjacent strips 8, 12, may hook said gap or step and make the connection element 36 itself slide, parallel to the prevailing longitudinal direction L-L.
  • connection element 36 has a pair of indentations or weakenings 84, preferably arranged on a concave side 88 of the connection element 36. Said indentations or weakenings 84 are preferably arranged towards the ends 44 of the connection element and create a sort of elastic hinge around which end branches 92 of the connection element 36 may elastically flex.
  • the strips 8, 12 are placed adjacent to the respective lateral edges 24, arranged parallel to each other along the longitudinal direction L-L, taking care to insert at least one connection element 36 between two adjacent strips so as to engage both seats 28 of said strips 8, 12.
  • connection element creates an undercut when separating the strips in the vertical direction Z-Z.
  • connection elements 36 and the relative seats or perimeter recesses 28 At the end of the laying of the parquet 4, all the strips will be suitably placed adjacent and fixed to each other by virtue of the shape coupling between the connection elements 36 and the relative seats or perimeter recesses 28.
  • the disassembly tool 64 is used to perform the reversible and non-destructive disassembly.
  • the disassembly tool 64 is gripped and the foil 72 is inserted through the joint 32 between two consecutive strips 8, 12.
  • the use of the foil depends on the type of connection element used.
  • connection element 36 it is sufficient to make the foil 72 slide inside the joint 32 along the prevailing longitudinal direction L-L. In this manner, when the foil intercepts the connection element 36, conventionally arched, it will tend to press such connection element 36 so that it is brought inside the seat 28 which houses the ends 44. In this manner, there is no longer any undercut which may prevent the lifting of said strips in the vertical direction. If the connection element 36 is elastically deformable, then it will also be possible to reuse the connection element 36 for the subsequent assembly of the parquet, since it behaves like a spring. If, instead, the connection element 36 is plastically deformable, after the flattening thereof, it will not return to the initial configuration thereof and must therefore be replaced.
  • the parquet, the kit and the assembly and disassembly method according to the invention allow to overcome the drawbacks presented in the prior art.
  • the present invention allows to disassemble a single strip from the parquet in a reversible manner, i.e., without in any way damaging the strip itself or the one adjacent thereto.
  • the disassembly operation and the subsequent assembly is particularly simple and quick to perform.
  • the kit is particularly convenient for parquet fitters and/or maintenance technicians to use.
