Definitions
- the present invention relates to a flooring material according to the preamble of claim 1, comprising sheet-shaped floor elements which are joined by means of joining members.
- Such flooring material is known from WO 01/02669 .
- Prefabricated floor boards provided with tongue and groove at the edges are quite common nowadays. These can be installed by the average handy man as they are very easy to install.
- Such floors can, for example, be constituted of solid wood, fibre board or particle board. These are most often provided with a surface layer such as lacquer, or some kind of laminate.
- the boards are most often installed by being glued via tongue and groove.
- the most common types of tongue and groove are however burdened with the disadvantage to form gaps of varying width between the floor boards in cases where the installer hasn't been thorough enough. Dirt will easily collect in such gaps. Moisture will furthermore enter the gaps which will cause the core to expand in cases where it is made of wood, fiber board or particle board, which usually is the case.
- the floor boards are provided with a locking device at the rear sides.
- the floor boards are provided with profiles on the lower side at a first long side and short side. These profiles, which extends outside the floor board itself, is provided with an upwards directed lip which fits into grooves on the lower side of a corresponding floor board. These grooves are arranged on the second short side and long side of this floor board.
- the floor boards are furthermore provided with a traditional tongue and groove on the edges. The intentions are that the profiles shall bend downwards and then to snap back into the groove when assembled.
- the profiles are integrated with the floor boards through folding or alternatively, through gluing.
- the floor boards may be joined by turning or prizing it into position with the long side edge as a pivot point. It is then necessary to slide the floor board longitudinally so that it snaps into the floor board previously installed in the same row. A play is essential in order to achieve that. This play seems to be marked A in the figures. A tolerance of 0. 2mm is mentioned in the application. Such a play will naturally cause undesired gaps between the floor boards. Dirt and moisture can penetrate into these gaps.
- WO 00/47841 describes floor boards that are joined by being pressed downwards.
- the floor boards are provided with lower joining lips at two adjacent edges while the two remaining edges are provided with upper joining lips.
- the lower joining lips are provided with essentially vertical lower lip surfaces arranged parallel to the closest edge.
- the lower lip surfaces are intended to interact with mainly vertical upper lip surfaces arranged on the upper joining lips.
- Two joined adjacent floor boards are hereby locked together in the horizontal direction.
- the joining lips are furthermore provided with one or more heels intended to snap join with recesses adapted thereto which, by being provided with essentially horizontal locking surfaces, limits vertical movement between two joined adjacent floor boards.
- WO 97/47834 does also show how the tongue and groove with heels and recesses according to the invention is tooled by means of cutting machining.
- This invention does also have the disadvantage that the best mode of joining floor boards includes longitudinal sliding for joining the short sides of the floor boards, which also here will require a play which will cause unwanted gaps between the floor boards. Dirt and moisture can penetrate into these gaps.
- the invention relates to flooring material comprising sheet-shaped floor elements with a mainly square or rectangular shape, which floor elements are provided with edges, a lower side and an upper decorative layer, whereby the floor elements are intended to be joined by means of joining members.
- the floor elements are provided with male joining members on a first edge, while a second edge of the floor elements is provided with a female joining member, whereby the male joining member is provided with a tongue and a lower side groove while the female joining member is provided with a groove and a cheek, the cheek being provided with a lip.
- the floor elements are intended to mainly be joined together by tilting the floor element to be joined with an already installed floor element or a row of already installed floor elements, with the male joining member of the floor element angled downwards, and the first edge is allowed to be mainly parallel to the second edge of the already installed floor element or elements.
- the tongue of the tilted floor element is inserted into the groove of the female joining member of the already installed floor element or elements, whereby the tilted floor element is turned downwards, with its lower edge as a pivot axis, so that the lip eventually snaps or falls into the lower side groove where the decorative upper layer of the floor elements are mainly parallel.
- the floor elements, on a third edge, are provided with a male vertical assembly joining member, while a fourth edge is provided with a female vertical assembly joining member, the fourth edge being arranged on a side opposite to the third edge.
- Two adjacent edges of a floor element, at the same time, and in the same turning motion, can be joined with a floor element adjacent to the first edge and a floor element adjacent to the third or fourth edge, wherein the male vertical assembly joining members are provided with mainly vertical lower cheek surfaces arranged parallel to the closest edge.
- the lower cheek surfaces are intended to interact with mainly vertical upper cheek surfaces arranged on the female vertical assembly joining members so that two joined adjacent floor elements are locked against each other in a horizontal direction.
- the male vertical assembly joining members are provided with a snapping hook and the female vertical assembly joining members are provided with a matching undercut.
- the snapping hook and matching undercut by being provided with mainly horizontal locking surfaces, limit the vertical movement between two joined adjacent floor elements, and the snapping hook is positioned at an inward position with respect to the upper edge of the respective floor element and a guiding angle is formed above the undercut.
- the force needed to overcome the static friction along the joint between two completely assembled male and female joining members is preferably larger than 10N per meter of joint length, suitably larger than 100N per meter of joint length.
- the joint between a third and a fourth edge of two joined floor elements preferably comprises contact surfaces which are constituted by the horizontal locking surfaces of the under cuts and hooks, the mainly vertical upper cheek surfaces and lower cheek surfaces as well as upper mating surfaces.
- the joint between two joined floor elements suitably also comprises cavities.
- the snapping hook is constituted by a separate spring part which is placed in a cavity.
- the undercut is constituted by a separate spring part which is placed in a cavity.
- the spring part is suitably constituted by an extruded thermoplastic profile, a profile of thermosetting resin or an extruded metal profile.
- the flooring material including the floor boards above is most suited when installing floors where it isn't desired to use glue. It is, however, possible to use glue or twin-faced adhesive tape in order to make the installation irreversibly permanent.
- the glue or tape is then suitably applied on, or in connection to, possible cavities or faces below the upper mating surfaces.

Description
- The present invention relates to a flooring material according to the preamble of
claim 1, comprising sheet-shaped floor elements which are joined by means of joining members. Such flooring material is known fromWO 01/02669 - Prefabricated floor boards provided with tongue and groove at the edges are quite common nowadays. These can be installed by the average handy man as they are very easy to install. Such floors can, for example, be constituted of solid wood, fibre board or particle board. These are most often provided with a surface layer such as lacquer, or some kind of laminate. The boards are most often installed by being glued via tongue and groove. The most common types of tongue and groove are however burdened with the disadvantage to form gaps of varying width between the floor boards in cases where the installer hasn't been thorough enough. Dirt will easily collect in such gaps. Moisture will furthermore enter the gaps which will cause the core to expand in cases where it is made of wood, fiber board or particle board, which usually is the case. The expansion will cause the surface layer to rise closest to the edges of the joint which radically reduces the useful life of the floor since the surface layer will be exposed to an exceptional wear. Different types of tensioning devices, forcing the floor boards together during installation can be used to avoid such gaps. This operation is however more or less awkward. It is therefore desirable to achieve a joint which is self-guiding and thereby automatically finds the correct position. Such a joint would also be possible to utilize in floors where no glue is to be used.
- Such a joint is known through
WO 94/26999 - According to
WO 94/26999 -
WO 00/47841 - It is also known through
WO 97/47834 WO 94/26999 WO 97/47834 - It is, through the present invention, made possible to solve the above mentioned problems whereby a floor element which can be assembled without having to be slid along already assembled floor elements has been achieved. It is thereby made possible to achieve tighter joints.
- The invention is defined in the appended claims.
- Accordingly, the invention relates to flooring material comprising sheet-shaped floor elements with a mainly square or rectangular shape, which floor elements are provided with edges, a lower side and an upper decorative layer, whereby the floor elements are intended to be joined by means of joining members. The floor elements are provided with male joining members on a first edge, while a second edge of the floor elements is provided with a female joining member, whereby the male joining member is provided with a tongue and a lower side groove while the female joining member is provided with a groove and a cheek, the cheek being provided with a lip. The floor elements are intended to mainly be joined together by tilting the floor element to be joined with an already installed floor element or a row of already installed floor elements, with the male joining member of the floor element angled downwards, and the first edge is allowed to be mainly parallel to the second edge of the already installed floor element or elements. The tongue of the tilted floor element is inserted into the groove of the female joining member of the already installed floor element or elements, whereby the tilted floor element is turned downwards, with its lower edge as a pivot axis, so that the lip eventually snaps or falls into the lower side groove where the decorative upper layer of the floor elements are mainly parallel.
- The floor elements, on a third edge, are provided with a male vertical assembly joining member, while a fourth edge is provided with a female vertical assembly joining member, the fourth edge being arranged on a side opposite to the third edge.
Two adjacent edges of a floor element, at the same time, and in the same turning motion, can be joined with a floor element adjacent to the first edge and a floor element adjacent to the third or fourth edge, wherein the male vertical assembly joining members are provided with mainly vertical lower cheek surfaces arranged parallel to the closest edge. The lower cheek surfaces are intended to interact with mainly vertical upper cheek surfaces arranged on the female vertical assembly joining members so that two joined adjacent floor elements are locked against each other in a horizontal direction. The male vertical assembly joining members are provided with a snapping hook and the female vertical assembly joining members are provided with a matching undercut. The snapping hook and matching undercut, by being provided with mainly horizontal locking surfaces, limit the vertical movement between two joined adjacent floor elements, and the snapping hook is positioned at an inward position with respect to the upper edge of the respective floor element and a guiding angle is formed above the undercut. - The force needed to overcome the static friction along the joint between two completely assembled male and female joining members is preferably larger than 10N per meter of joint length, suitably larger than 100N per meter of joint length.
- The joint between a third and a fourth edge of two joined floor elements preferably comprises contact surfaces which are constituted by the horizontal locking surfaces of the under cuts and hooks, the mainly vertical upper cheek surfaces and lower cheek surfaces as well as upper mating surfaces.
- The joint between two joined floor elements suitably also comprises cavities.
- According to one embodiment of the invention the snapping hook is constituted by a separate spring part which is placed in a cavity. Alternatively the undercut is constituted by a separate spring part which is placed in a cavity. The spring part is suitably constituted by an extruded thermoplastic profile, a profile of thermosetting resin or an extruded metal profile.
- The flooring material including the floor boards above is most suited when installing floors where it isn't desired to use glue. It is, however, possible to use glue or twin-faced adhesive tape in order to make the installation irreversibly permanent. The glue or tape is then suitably applied on, or in connection to, possible cavities or faces below the upper mating surfaces.

The lower cheek surfaces 21 are intended to interact with mainly vertical upper cheek surfaces 22 arranged on the female verticalassembly joining members 10IV so that two joinedadjacent floor elements 1 are locked against each other in a horizontal direction. The male verticalassembly joining members 10III are moreover provided with two snappinghooks 23 while the female verticalassembly joining members 10IV are provided with matching undercuts 24, which by being provided with mainly horizontal locking surfaces limits the vertical movement between two joinedadjacent floor elements 1. - The joint between a third and a
