Definitions
- the invention relates to a device for joining floor boards and comprising an elongated, plate-shaped body with a leg adapted to engage a longitudinal groove in each of the adjoining floor boards.
- Devices for mounting floor boards are known in form of substantially U-shaped clips.
- the legs of these clips are formed by way of bending and are optionally provided with barbs in such a manner that they are locked in grooves on the bottom side of the floor boards.
- Such clips are for instance known from EP-PS No. 126,764.
- the object of the clips is to keep adjoining floor boards together and optionally to press said boards together.
- both the legs of the clips and the grooves receiving said legs can be shaped rather large without strict tolerance standards without acting on the already laid flooring.
- a flooring depends highly on the accuracy of the control of each floor board when subjected to oscil ⁇ lating effects, such as moisture.
- the object of the invention is therefore to provide a device suited for use in connection with thin floorings , especially floorings made of solid undressed wood and subjected to a varying moisture of the atmosphere, and where said device allows a simple and fast laying of the looring.
- the device according to the invention is characterised in that the legs are shaped at a distance from the ends of the plate—shaped body.
- the resulting flooring can be mounted in a relatively easy and fast manner at the same time as it is reliable, which is due to the fact that the devices are fixedly and non— iltably arranged in each groove, said device comprising members abutting the bottom side of the floor board on each side of the groove.
- the device is advan ⁇ tageous both, during the laying procedure and in the already laid flooring.
- the device is fastened by one leg thereof being arranged in the groove of one board where it is secured in such a manner that it cannot be moved, i.e. it cannot be turned or tilted away from the bottom side of the floor board.
- the device does not tend to fall out during the laying of the board in the desired horizontal posi ⁇ tion so as to be ready for being joined with yet another board.
- the groove of the other board is easily caused to engage the second leg of the device while the boards are pushed together by means of the tongue/groove connec ⁇ tion. If the device had been able to tilt relative to the first groove it engaged, it would have fallen out easily and thereby destroyed the rim of the relatively accurately shaped groove and optionally also the fine shaping tolerance of the leg. Then it would often be necessary to replace the device in question by a new device and arrange said new device on a new location relative to the groove.
- the connection between the device according to the invention and each board is thus capable of absorbing the torque in both directions about an axis of rotation extending along the groove of each board. As a result, a reliable keeping together of the boards of the already laid flooring is ensured.
- the legs of the device may be shaped by bending two webs projecting away from one another, said webs resulting from a punching out of a substantially I-shaped opening in each end of the plate- shaped body, where the two transverse legs of the I extend in the longitudinal direction of the plate—shaped body.
- the resulting device is particularly simple with a reliable, symmetrical structure.
- the bent webs may according to the invention be of a substantially hook-shaped cross section, whereby a shape is obtained which ensures that the legs are easily inserted in a groove and are locked therein.
- the bent webs may be bent substantially perpendicular from the plate-shaped body at a distance from the location where the webs extend from the plate-shaped body and project into the punched out portion.
- Fig. 1 is a top view of a preferred embodiment of a device according to the invention.
- Fig. 2 is a sectional view on a larger scale taken along the line II-II of Fig. 1, and
- Fig. 3 illustrates a portion of a flooring laid by means of the device of Figs. 1 and 2.
- the device shown in the drawing comprises an elongated, plate-shaped body 1 of a substantially rectangular shape.
- the device comprises an upwardly projecting leg 2, 3 at each end, said legs being shaped integral with the plate—shaped body 1 by way of bending.
- the legs 2 and 3 are produced in connection with their respective punched out I- or H—shaped opening 4 and 5, respectively. These openings 4 and 5 are shaped symmet ⁇ rically about the longitudinal central axis of the plate—shaped body 1 a short distance from each end of said plate—shaped body.
- the parallel legs of the I or the H extend parallel to the longitudinal symmetrical axis of the plate—shaped body 1.
- the legs 2 and 3 are shaped by the punched out web 6 and 7, respectively, being bent. The webs 6 and 7 project from the side of the opening 4, 5 adjacent the centre of the plate—shaped body 1 and Into said opening.
- each leg 2, 3 is bent out from the plane of the plate—shaped body 1 a short distance from the connection of the web 6, 7 with the plate-shaped body 1 in such a manner that a short portion 8 and 9, respectively, of the web is flushing with the plate-shaped body 1.
- the radius of curvature of each leg 2, 3 at the transition 10 to the plate-shaped body 1 can therefore be shaped relatively small.
- Each leg 2 and 3 is of a substantially hook-shaped form with the result that a sharp edge 11 is formed.
- the sharp edge ensures a good engagement of the leg and the board in question.
- the legs 2 and 3 are, as mentioned, shaped on the side of the openings 4 and 5 adjacent the centre of the plate-shaped body 1 while being simultaneously bent in such a manner that the sharp edge 11 on the hook-shaped leg 2 and 3 faces away from the centre of the plate- shaped body 1.
- the legs 2 and 3 provide a particularly good resistance against the tendency of the floor boards to expand at the same time as the sharp edge 11 has a tendency to bite itself into the board in question by cutting into the wood on the same side as the portion of the plate—shaped body which extends from the legs 2, 3 to the ends.
- a self-in- creasing resistance is obtained against a turning or tilting of the device 1 relative to each board.
- Fig. 3 illustrates two abutting floor boards 12 and 13 engaging one another by means of a groove/tongue connec- tion 14.
- Each board 12 and 13 comprises a longitudinal groove 14 and 15, respectively, on the bottom side, said grooves being manufactured with an accurate position relative and parallel to the longitudinal rims of the board 12 and 13.
- the grooves 14 and 15 are simultaneous- ly manufactured with relatively fine tolerances.
- the boards 12 and 13 are mounted on the bottom side by means of a device of the type shown in igs. 1 and 2, where the plate—shaped body 1 extends transverse to the groove/tongue connection 14 of the boards 12 and 13 with a leg 2, 3 received in their re ⁇ spective groove 14, 15. It appears clearly, that the plate—shaped body extends to each side relative to each groove 14, 15 and is thereby abuttingly arranged against the boards 12 and 13 on both sides of the grooves 14 and 15.
- the device according to the Invention is preferably made of plate—shaped spring steel of a thickness of about 0.75 mm, a width of 20 mm, and a length of 135 mm.
- the height of the legs relative to the plate-shaped body 1 is suitably of a dimension 3.1 mm, whereas their mutual distance is 111 mm.
- the distance between the side of the legs 2, 3 perpendicular to the plate-shaped body 1 ad ⁇ jacent the centre and the associated sharp edge 11 Is advantageously about 2.5 mm.
- Such a device is suited for use in connection with 8 mm thick solid boards of a width of 113.9 mm.
- the associated grooves are suitably 2.35 mm wide and 3.5 mm deep. Boards of a width of 129.0 mm involve the use of devices made of spring steel of a length of 150 mm.
- the mutual distance of the legs is 126.5 mm. All the remaining dimensions are the same as above.
- Each leg may for instance be shaped as a double leg adjacent both longitudinal sides of the plate—shaped body with an Intermediary portion extending as an extension past the legs to the ends of the plate—shaped body 1.
