Description

PROCESS OF LAYING FLOORBOARDS

BACKGROUND OF THE INVENTION
Technical Field This invention refers to a process of laying and mechanically jointing floorboards which have a tongue one of their longitudinal and transverse sides and a groove matching the tongue on their opposite longitudinal and transverse sides, the tongue and groove being designed to permit boards to engage with one another horizontally.
Description of the Related Prior Art A number of floorboard-laying procedures are described in US Patent nos. 5,860,267 and 6,023,907. In the known procedures, the boards are placed in an initial row and at least one board is placed in the second row and is jointed on its longitudinal side to boards in the first row. A new board is partially jointed on its transverse side to the board in the second row. The new board is placed flat on the floor. The board from the second row and the new board are then lifted together and tilted against the first row.
The new board is then shifted relatively to the board from the second row until it engages on its longitudinal side with boards in the first row.

The second and the new board are then swung down again to form a joint with the second and the first row. In a procedure which is also described, the new board is first shifted horizontally towards the first row until the boards engage on their longitudinal edges and are then shifted relatively to the first row towards the transverse side of the board in the second row until the boards engage.

The first procedure described is quite complicated to execute because the person laying the floor must use one hand to swing the boar.ds up and use the other to push in the new board which is tilted. If the new board is twisted, there is a risk of the tongue splitting off or of the groove breaking apart. The mere deadweight of a board can cause damage to the tongue and groove joint when the boards are lifted from the floor. This means, essentially, that thi_s laying procedure can only be carried out by two persons.

In order to permit a new board to be first jointed on its longitudinal side with the preceding row of boards and then shifted longitudinally on to the board in the second row, the tongue and qroove interface has, according to US
Patent No. 6,023,907, a tolerance A at the joint.
Providing such a tolerance at the joint has, however, the disadvantage that the boards can be shifted not only along the line of the joint but also transversely to it. In consequence, the attachment between adjoining boards is not moisture-proof aiid moisture can penetrate. This is a particular problem in the case of MDF (medium density fibreboard) or HDF (high density fibreboard) laminated boards because there is a risk of the core swelling because of moisture penetration, which can ruin a floor.
It is suggested in. the cited documents that this risk should be eliminated by inserting a moisture-proof substance between th(=_ joints, such as silicon or a rubber strip. This step of course complicates the floor laying procedure. In addition, ensuring that the joints stay
2 really moisture-proof requires an exact method which cannot be expected vJhen "snap-on interfaces" of this kind are used by home handymen.

For this reason "snap--on interfaces", that is to say, boards made so that t:wo attached boards engage or lock together at the joint by means of a tongue and groove, are designed to have a prestressing instead of a tolerance at the interlock, which ensures that the boards are so jointed that they fit tightly together, especially on the upper side. Two boai-ds longitudinally jointed together with pre-stressing arid measuring several metres in length can, because of frict:ion at the joint, be shifted in relation to one another only with a considerable expenditure of energy. In order to joint the newly inserted board with t:he transverse side of the board already positioned in the second row, the person laying the floor must generally use force and drive the new board in the desired direction by means of hammer blows. A

careless hammer blow may not only ruin the transverse side of the new board, made fragile by the interface, but also cause damage to the upper edge of the joint which may not be noticed. If, as a result of such damage to the plane of separation, the boards can no longer be laid tightly, moisture can subsequently penetrate and ruin the floor as described above.

German Patent publication 200 02 413 U1 provides a description of boards with snap-on interfaces, laid in such a manner that they are first pushed into one another on their l.ongitudinal side and the newly laid board,
3 already jointed longitudinally with a board previously laid, is shifted longitudinally by hammer blows on its transverse side until its opposed front side engages with the front side of a board previously laid. The laying procedure described in the document does not permit the person laying the floor to joint the narrow sides first and then hammer the board on its longitudinal side so as to drive it far enough transversely for it to engage on its longitudinal side with the row of boards previously laid.

SUMMARY OF THE INVENTION

In view of this problem, it is proposed to develop a floor-laying procedure which even inexperienced persons can use simply and quickly to lay mechanically interlocking boards ("snap-on interfaces") so constructed that they are subject to pre-stressing at the joint.

According to a first aspect of the invention, there is provided a process of laying and mechanically jointing floorboards which have, on one longitudinal side and one transverse side, a tongue, and on an opposite longitudinal side and an opposite transverse side, a groove matching the tongue, whereby boards inserted into one another engage horizontally, the process comprising: (a) jointing a plurality of boards by engaging the transverse and the opposite transverse sides of the plurality of boards to lay a first row on a floor of a room; (b) jointing a first board of a second row by engaging the first board of the second row with one or two boards in the first row using the tongue on the longitudinal side of the first board of the second row and the groove on the opposite longitudinal side of the
4 one or two boards in the first row; (c)pushing a tongue on the transverse side of a second board in the second row into a groove on an opposite transverse side of the first board in the second row in a direction of the first row; and (d) engaging the, second board of the second row with one or two boards of the first row using a tongue on the longitudinal side of the second board in the second row and a groove on the opposite longitudinal side of the one or two boards in the first row.

The boards can also be laid in such a way that a new board in a second row is not inserted using its tongue into the groove of a board previously laid but is pushed using its groove on to the tongue of a board previously laid.

The procedure to which the invention refers requires the faces inserted into one another to be shifted in relation to one another only over a short distance, thus minimising friction (the surface subject to friction increases linearly as the "threading" of the tongue and groove proceeds). The force required to overcome the increase in friction can be exerted by hand without the aid of a tool, so that the risk of damaging edges is permanently eliminated.

According to a second aspect of the invention, there is provided a process of laying and mechanically jointing floorboards which have, on one longitudinal side and one transverse side, a tongue, and on an opposite longitudinal side and an opposite transverse side, a groove matching the tongue, whereby boards inserted into one another engage horizontally, the process comprising: (a) jointing a plurality of boards by engaging the transverse and the opposite transverse sides of the plurality of boards to lay
5 a first row on a floor of a room; (b) jointing a first board of a second row by engaging the first board of the second row with one or two boards in the first row using the tongue on the longitudinal side of the first board of the second row and the groove on the opposite longitudinal side of the one or two boards in the first row; (c) pushing a groove on the transverse side of a second board in the second row into a tongue on an opposite transverse side of the first board in the second row in a direction of the first row; and (d) engaging the second board of the second row with one or two boards of the first row using a tongue on the longitudinal side of the second board in the second row and a groove on the opposite longitudinal side of the one or two boards in the first row.

According to a third aspect of the invention, there is provided a process of laying and mechanically jointing floorboards which have a tongue on one longitudinal side and one transverse side and a groove matching the tongue on the opposite longitudinal side and transverse side, the tongue and the groove having a corresponding locking projection and indentation and being designed so that boards inserted into one another engage horizontally, the process comprising:

(a) jointing a plurality of boards and making them engage on their transverse sides in order to lay a first row on the floor; (b) jointing a first board of a second row and making it engage with one or two boards in the first row by means of the tongue and groove joint on the longitudinal side for purposes of starting a second row; (c) aligning a corner of the first board with a corner of a second board for the second row on the transverse sides; (d) sliding, toward the longitudinal side of the board in the first row, the groove
6 ~ . .. . . .. . .... . .. . . . ..... .. ... ..... ..,.,....

or tongue of the second board on the transverse side into the respective tongue or groove on the transverse side of the first board in the second row, the tongue and respective groove remain engaged during the sliding; and (e) jointing the second board with one.or two boards in the first row on the longitudinal side.

BRIEF DESCRIPTION OF THE DRAWINGS

The process of the invention is described in more detail below with reference to the accompanying drawings, in which:
Figure 1 is a schematic illustration of two floorboards jointed together, in cross-section; and Figure 2 is a plan of partially laid flooring according to one form of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown in the accompanying drawings, the boards P have on their longitudinal sides 1 and their transverse sides 2, tongues 3 and grooves 4 in matching opposite positions. On the underside of the tongue 3 there are projections, not described here in further detail, which can engage in recesses, also not described here in further detail, on the lower lip of the groove 4. The boards P can be locked together by pushing the tongue 3 into the groove 4. The constructional details of the boards will not be further explained. In this regard, reference may be made to German patent No. 198 21 200.
7 For the purpose of laying the floor, the first step is to make a first row I of boards P11, P12, P13... Pln from wall to wall of a room, these boards P11... Pln being jointed on their transverse sides. In a following row II, a first board P21 is jointed on its longitudinal side with the first board P11 in the previously laid first row I. A board P22, which is to be laid next, is then fitted, starting from its longitudinal side, by its tongue 3 into the groove 4 of the board P21 and is shifted towards the first row I, with the tongue 3 sliding in the groove 4 until the board P22 on its longitudinal side engages with the boards P11 and P12. As board P22 is shifted, its tongue 3 passes over a longer distance into the groove of board P21 until the two boards P21, P22 are completely jointed together along their transverse side 2. It is also possible to lay a floor in accordance with this procedure by mounting board P22r using its groove 4, on the tongue 3 of the board P21.
