Definitions
- This invention relates to a board, which is made of a material based on wood, preferably particle board, which is suitable to use when laying down floor boards, the board having an essentially rectangular shape with two long sides and two short sides, and at least the one but preferably both short sides having a profile provided with tongues and grooves, which, when laying two boards together, makes possible to form an essentially smooth transition part between the boards, and wherein the tongue and the groove are designed in that way that, when laying together two essentially substantially uniform boards (19, 20), the other board (20) being turned upside-down in relation to the first one (19) the tongues of the two boards will fit exactly into the grooves of the two boards, whereby the joint between the boards (19, 20), put together, gets such a strength that it could be placed between two adjacent beams in a floor with beams.
- This invention intends to improve the known technique and to provide a board based on wood, preferably a particle board, which makes possible also to place the joint between two boards, put together, between two beams for a floor, where a joint with improved strength is provided.
- a board of the kind mentioned by way of introduction which has the features mentioned in claim 1.
- FIG. 1 shows a floor with beams, where the particle board according to the invention is used
- Fig. 2 shows a joint between two particle boards, put together, according to the invention
- Fig. 3 shows the same picture as in Fig. 1 but with that difference that the particle boards have been drawn out a small distance from each other.
- Fig. 1 a plurality of rectangular particle boards 1 according to the invention, laid down on a great number of beams 2 for creating a floor with beams.
- the short sides 3 of the particle boards are provided with the new profile, which makes possible for the joint 4 between two boards 5, 6, put together, to be positioned between two adjacent beams 7, 8. Due to that fact the mounting of the particle boards can be made continuously, which means that, when there is a rest part of a board when finishing a row, it is possible to start the next row with that rest part. This fact leads to a very effective laying down of particle boards with a minimum of material wastage.
- the long sides of the particle boards are provided with the new profile, adjacent boards interfering with each other. Also that fact contributes to strengthen the joint between the short sides of the boards.
- the new profile of the short- and long sides of the particle boards leads to an improved function of the joint between two particle boards, put together, and this fact has also that advantage that the number of screws for fastening the particle boards on the beams can be reduced in relation to known technique.
- the profile has the following design, seen from the top surface 11 of the particle board in relation to which the tongue has a position above the groove:
- the profile is designed in that way that the two particle boards 19, 20, which shall be put together, are essentially uniform but are reversed when being put together so that the top surface of the one particle board 19 is directed upwards, whereas the top surface of the other board 20 is directed downwards.
- the advantage with this arrangement is that only one tool needs to be used, and that, principally, it would be possible to use optional side, directed upwards, when the floor is mounted.
- the obliquely bevelled parts 12, 18 of the profile portion of the one particle board when co-operating with corresponding obliquely bevelled parts as of the profile portion of the other particle board 20, has the effect that the forces arising when loading the joint are distributed out to all parts of the joint with an increased strength as a result.
- To this high strength of the mentioned joint contributes also that fact that the new profile is well counterbalanced.
- Fig. 3 where it can be seen that the floor profile is "symmetrical" with regard to the line 15, i.e. the volume of the tongue 13 is essentially the same as the volume of the groove 16.
Description
- An obliquely backwards-directed,
straight portion 12, which forms an angle of 20-30° with the vertical line, and which passes over to an obliquely downwards- and forwards-directed,rounded portion 13, which functions as a tongue, and which after the rounding extends essentially straightly backwards approximately at the middle of the depth, i.e. the thickness, of the particle board; - The mentioned
extension 14 backwards has such a length that it reaches beyond aprolongation line 15 through theportion 12 towards the underside of the particle board and passes over to a backwards directed,rounded portion 16, which functions as a groove, and which has an obliquely downwards- and forwards-directed,straight portion 17, which passes over to an obliquely backwards-directed,straight portion 18, which extends to the underside of the board, and which has such a position that it essentially coincides with the mentionedprolongation line 15 through theportion 12.
Claims (5)
- A board, made of a material based on wood, which is suitable to use when laying down floor boards, the board having an substantially rectangular shape with two long sides and two short sides, and at least the one but preferably both short sides having a profile provided with tongues and grooves, which, when laying two boards together, makes possible to form an substantially smooth transition part between the boards, the tongue and the groove are designed in that way that, when laying together two substantially uniform boards (19, 20), the other board (20) being turned upside-down in relation to the first one (19), the tongues of the two boards will fit exactly into the grooves of the two boards, whereby the joint between the boards (19, 20), put together, gets such a strength that it could be placed between two adjacent beams in a floor with beams characterized in that the profile has the following design, seen from the top surface (11) of the board (19) in relation to which the tongue has a position above the groove, the board being assumed to have taken horizontal position:An obliquely backwards-directed, substantially straight portion (12), which passes over to a projecting, rounded portion (13), which functions as a tongue;The projecting, rounded portion (13) passes over to a backwards-directed rounded portion (16), which functions as a groove;The backwards-directed rounded portion (16) has a forward-directed lower delimitation surface (17), which passes over to an obliquely backwards-directed substantially straight portion (18), that extends to the underside of the board (19).
- A board according to claim 1, characterized in that the lower delimitation surface (17) of the backwards-directed rounded portion (16) is directed obliquely downwards.
- A board according to claim 1 or 2, characterized in that an imagined prolongation line (15) through the obliquely backwards-directed portion (12) close to the top surface (11) of the board (19) substantially coincides with the obliquely backwards-directed portion (18) that extends to the underside of the board (19), said prolongation line forms an angle of 20-30° with the normal of the top surface (11) of the board, and in that the tongue (13) has an extension (14) backwards with such a length that it reaches beyond the imagined prolongation line (15).
- A board according to claim 3, characterized in that the mentioned profile is substantially point-symmetrical to the intersection of the prolongation line (15) and an imagined half-vertical thickness of the board.
- A board according to any one of the preceding claims, characterized in that also the two long sides of the board have the said profile.
