Abstract

A board 1 for installing a wooden floor in a herringbone pattern has two long sides of which a first long side 7 is provided with a main groove 15 and a second long side 9 is provided with a main tongue 17, and has two short sides 11, 13, which are both provided with a transverse tongue 19, 21. The two transverse tongues on the short sides are disposed right opposite to each other and in the middle of the short side.

The second long side 9 is further provided with two auxiliary grooves 23, 25 spaced apart from each other which are each disposed adjacent to an end of the long side, while the distance 27 between an end of a transverse tongue 19, 21 and the most remote long side is as great as the distance 29 between a short side and the most remote end of the auxiliary groove 23, 25 adjacent to this short side.

Description

Field of the invention

The invention relates to a board for installing a patterned wooden floor, the board having an under side on which the board is installed on a sub-floor on installation, a top side forming a walking surface after installation, two long sides of which a first long side is provided with a main groove and a second long side is provided with a main tongue, and two short sides of which at least one short side is provided with a transverse tongue.

State of the art

A board of this type is known from US 1 787 027 A . With this known board a groove is present in the other short side. When these boards are installed in a herringbone pattern the tongues are fitted into grooves of adjacent boards so that the boards are secured relative to each other and cannot be displaced relative to each other. Installing a herringbone pattern requires, in addition to suchlike boards, also boards having a mirror inverted appearance. Worded differently: for installing a herringbone pattern both 'right hand' and 'left hand' boards are needed.
A disadvantage of this is that it is necessary to manufacture two different types of boards and that there is a chance of exchanging the two types. As a result, it is necessary for the person installing the floor to constantly stay alert and it regularly happens that a wrong board is used which has to be remedied then. It is alternatively possible that too many boards of one type and too few boards of the other type are delivered, so that first boards have to be exchanged before the floor can be finished.

Summary of the invention

It is an object of the invention to provide a board of the type defined in the opening paragraph with which a floor can be installed in a pattern, for example, a herringbone pattern and with which the disadvantages of the known boards described above are not found. To this end the board according to the invention is characterized in that the other short side is provided with a further transverse tongue, where the two transverse tongues on the short sides are oppositely disposed and are present in the middle of the short side, and in that the second long side is further provided with two auxiliary grooves spaced apart from each other and which are each disposed adjacent to an end of the long side, where the distance between an end of a transverse tongue on the short side and the most remote long side is equal or substantially equal to the distance between a short side and the most remote end of the auxiliary groove in the second long side adjacent to this short side. For installing a floor in a herringbone pattern with the boards according to the invention no 'left hand' and 'right hand' boards are needed, but a single type of boards can suffice, whereas yet all boards are in locking engagement with each other and cannot be displaced relative to each other. In consequence, one can never be mistaken when taking a board for installing the floor and it cannot happen that too few of one type or too many of the other type of board are available.
It is observed that from WO 98/38401 A is known a board with which also a herringbone pattern can be installed without another 'mirror inverted' board being needed. However, with this known board grooves are provided in both short sides so that there is no bond between the short sides and the long sides disposed against them. This problem may be solved by fitting loose splines into the short ends, but this asks for additional activities during the installation operation plus the chance of the loose splines being forgotten sometimes. Besides, loose splines always provide suboptimal fit, because the loose splines need room.
Furthermore, it is observed that from US 2 187 672 A is known a board with which also a herringbone pattern can be installed without another 'mirror inverted' board being needed. One short side of this board has a groove while on the other short side a tongue is disposed so that there is a bond indeed between the short sides and the long sides. However, half the length of the long side is provided with a groove while the other half of the long side is provided with a tongue. For installing a herringbone pattern it is then necessary for the length of the board to be twice its width. This leads to constrictions as regards the appearance of the floor as a result of which the herringbone pattern is more difficult to recognize.
For installing the boards in a double herringbone pattern, an embodiment of the board according to the invention is characterized in that the second long side is provided with two further auxiliary grooves spaced apart from each other and disposed adjacent to the auxiliary grooves, which further auxiliary grooves are each disposed at a distance from the adjacent auxiliary groove, the distance being twice the distance between each auxiliary groove and the adjacent short side. For installing the boards in a triple herringbone pattern are available two still further auxiliary grooves which are also disposed at a distance of twice the distance between each auxiliary groove and the adjacent short side of the further auxiliary grooves.
For installing the boards in a block pattern, a further embodiment of the board according to the invention is characterized in that auxiliary grooves are disposed over the entire second long side, where adjacent auxiliary grooves are disposed at a distance twice the distance between each auxiliary groove and the adjacent short side.
For realizing optimal securing of the boards relative to each other, an embodiment of the board according to the invention is characterized in that the length of the transverse tongue on the short side is equal or substantially equal to the length of the auxiliary groove in the second long side, so that the transverse tongue on both ends is in locking engagement with the auxiliary groove.
For securing the boards relative to each other over the entire length, a further embodiment of the board according to the invention is characterized in that sub-grooves are disposed between the transverse tongue on the short side and the two long sides, so that the boards over their entire width are locked with their grooves and tongues.
A still further embodiment of the board according to the invention is characterized in that the main tongue on the second long side extends between the auxiliary grooves in the second long side. As a result, also on the long sides adjacent boards are in engagement with each other over a greater part of the length.
For causing adjacent boards to be in engagement with each other over a still greater part of the length, a further embodiment of the board according to the invention is characterized in that a spline is disposed between each auxiliary groove in the second long side and the most adjacent short side.
The main groove in the first long side preferably extends over the entire first long side, so that also the first long side is in interlocking engagement with an adjacent board over a maximum distance. In addition and as a result of this it is possible to install the boards also in a double herringbone pattern (install each time two boards abutting each other over the entire length and the pairs in a herringbore pattern). The transverse tongues on the short ends can then be fitted into the main groove present in the first long side, so that during the installation operation care should be taken not to shift the boards relative to each other, but in a floor once installed the boards are all in locking engagement anyway.
