Invention with reference to the attached
Figures are described. Same reference numerals in different
Figures denote the same objects. Show it:
1 a cross-sectional view of a floor panel having a first side edge;
2 two interconnected panels at the junction in the partial cross section;
3 a floor panel in cross-sectional view with a second side edge; such as
4 two interconnected panels at a second connection point in the partial cross section.
1 shows a floor panel 1 , which consists of a medium density or high density fiberboard (MDF or HDF). At the top 15 is the floor panel with a decorative layer 16 provided, for example, may be formed by a wood grain having paper layer, which is coated with a serving as a wear protection resin layer. On the bottom 7 can be a sound insulation layer 8th glued on to improve the footfall properties of the laid floor panels. As an alternative to using a HDF or MDF board, the panels can 1 be made of an OSB material (oriented strands board). At a first side edge, preferably at the longitudinal side of the panel 1 , is the panel 1 with a spring 10 and on the opposite side with a groove 3 Mistake. The groove 3 and the spring 10 extend over the full length of the side edge. At the spring 10 is an outwardly projecting, rounded nose provided in a rounded front area 11 passes. At this front area 11 closes at the bottom of the spring 10 a flattened, in the installed state in the substantially horizontal extending support area 12 on, over which the panels over 1 on a corresponding surface of the groove 3 a second panel 2 , as in 2 shown, supported.
To the support area 12 closes an oblique surface 13 with a corresponding lead 5 the corresponding groove 3 the second panel 2 a lock in the transverse direction Q causes. When assembled, the spring engages 10 in one through an upper lip 4 the groove 3 formed undercut, so that along the first side edge also takes place a lock in the vertical direction V. The lead 5 is through a the groove 3 final paragraph 9 formed, on its upper side a horizontally extending surface is formed. This surface serves as a support for a support area 14 , which adjoins the sloping surface 13 at the groove 10 followed. Through the support area 12 and the support area 14 a relatively large contact surface is provided on which the two panels 1 . 2 in the connected state to each other. The bevelled surface 13 causes, in conjunction with the projection 5 in the case of a force component acting from the top, a component of movement in the transverse direction toward one another, so that in the locked state in the case of a force component acting from above, the gap between the two panels 1 . 2 is reduced.
Paragraph 9 is formed so that in the transverse direction Q no contact between a vertically extending surface of the shoulder and an opposite, also vertically extending surface of the first side edge exists. So there is a free space 30 before, so that here no unwanted blocking effect and thus no gap between the two panels 1 . 2 at the top 15 may be present.
Between the spring 10 and the top 15 the panels 1 is an undercut 17 formed, which in the assembled state, a free space 18 is formed, can be absorbed in the abrasion or not removed chips from the manufacturing process. Likewise, a corresponding design of the rounded front area 11 provided so that at the top of the spring 10 in the assembled state also a free space 19 is formed, which can act as a dust bag.
Laying and locking two panels 1 . 2 done with such a profile picture in which the first panel 1 with the spring 10 angled to the second panel 2 is set and the spring 10 in the groove 3 of the second panel 2 is inserted. Subsequently, the angled first panel 1 pivoted about an axis parallel to the longitudinal direction of the first side edge, in this case in the clockwise direction, so that the rounded front area 11 in the groove 3 slides along until the support area 12 on the corresponding surface of the groove 3 lying flat. In this state, as in the 2 is shown by the undercut of the upper lip 4 and the lead 5 of the paragraph 9 achieved an effective locking in the vertical direction V and transverse direction Q.
In order not only to enable locking with another panel on two opposite side edges of one panel, a profile is formed on a second side edge, which extends at an angle, preferably a right angle to the first side edge, in the 3 is shown. Here, too, corresponding profiles are formed on opposite side edges, their interaction in the 4 is shown.
3 shows such a profile at a second side edge in cross-section, which is preferably formed on the transverse side of the panel. From the bottom 7 starting, is a step-shaped cutout 20 in the panel 2 incorporated an inner wall 21 and an outer wall 22 formed. Both on the inner wall 21 as well as on the outer wall 22 are positive locking elements 23 . 24 formed, milled out here, in the form of projections in corresponding undercuts 230 . 240 a corresponding recess 200 a second panel 1 intervention. In the cutout 20 is a paragraph 25 trained towards the bottom 7 protruding, wherein the Absatzaußenwandung of the outer wall 22 is formed and the paragraph inner wall 27 formed in the illustrated embodiment, an upwardly flared cross-section. The bottom of the heel 25 forms a head surface 26 that are parallel to the top 15 the panels 2 runs and on which the panel 2 in the mounted state via a corresponding base surface 280 a corresponding recess 200 a second panel 1 supported.
As an alternative to the illustrated embodiment, it is provided that the inner surface 27 substantially parallel to the outer wall 22 runs, leaving the heel wall 27 to the head area 26 forms an undercut. It is also envisaged that in addition to a substantial straight formation of the outer wall 22 at an acute angle α to the vertical, the outer wall 22 has a rounded shape or a vertical course. It is necessary that the positive locking element 24 over the trailing edge 28 the top 15 protrudes to a positive locking with the second panel 1 perform.
Above the positive locking element 24 is a recess 29 trained, which acts as a dust bag.
Unless the paragraph inside 27 as an undercut to the head area 26 is formed, an additional locking in the vertical direction is provided, in particular if the corresponding paragraph inner wall 270 of the paragraph above 250 is also designed as an undercut. A positive locking then takes place by a slight bending or elastic deformation of the profiles, so that the interlocking elements 23 . 24 and the undercut through the heel inside 27 with the corresponding undercuts 230 . 240 and the undercut through the Absatzinnenwandung 270 can effectively engage.
The one from the top 15 outgoing cutout 200 is formed such that it can receive the opposite profile, so that the head surface 26 on the one hand completely flat on the base surface 280 rests, on the other hand, the surfaces 15 the two panels 1 . 2 in the assembled state, as in the 4 is shown, complete in a plane and lie as flush as possible. Through the recess 29 above the positive-locking element 24 becomes a free space 290 created, which serves as a dust bag, the same applies to the free space 300 by a corresponding positioning of the inner wall 210 the cutout 200 is formed.
Like in the 4 can be clearly seen, an effective locking is given both in the transverse direction Q and in the vertical direction V, wherein the locking in the transverse direction positively by the paragraphs 25 . 250 is realized. A locking in the vertical direction V is effected by the locking elements 23 . 24 , the form-fitting in the undercuts 230 . 240 engage, wherein the positive locking elements 23 . 24 at spaced apart walls 21 . 22 are arranged. In addition, the positive-locking elements 23 . 24 arranged at different vertical levels, so that an upper locking point and a lower locking point is formed. The upper locking point is determined by the positive locking element 24 and the undercut 240 , the lower locking point through the positive locking element 23 and the undercut 230 educated.
The upwardly directed paragraph 250 is not formed over the entire length of the second side edge, but is over an area except for the base surface 280 milled off, with this cutout towards the first side edge with a spring 10 lies. Through this cut-out or non-training of the paragraph 250 can at a laying the first angularly inserted panels are lowered further down before, by a pulse-like assembly movement down a final locking on the second side edge, preferably the transverse side takes place.
Between the head area 260 of the paragraph 250 and the corresponding area of the cutout 20 is in the assembled state, a free space available, which is necessary so that the positive locking element 23 the undercut 230 can engage. Also, this space serves as a dust bag.
In addition to the formation of a panel with a groove 3 on one side edge, which is an upper lip 4 and a lower lip 6 can, by a corresponding profile design also on a lower lip 6 be waived, if in another way a lock in the transverse direction Q and vertical direction V is ensured. This locking is done so that no movement in the direction of the double arrows in the locked state is possible.
Due to the presented profile and the laying method described, it is possible to lay panels easily and quickly. The profile has the further advantage that on the special design of the spring 10 and the groove 3 on the one hand a slight swinging and locking, on the other hand, a stable support and thus the possibility of the most accurate adjustment of the height offset is given. Also, a secure locking of the first side edges in the vertical direction V and transverse direction Q is given and this profile can be particularly well milled in OSB panels.
The profile design on the second side edge allows a particularly durable positive lock on the second Seitenkan th, preferably the transverse sides of the panels, without complex additional equipment or special skills would be necessary during installation. In addition to the staggered positive locking elements, the large support surface prevents angling and thereby easy opening of the lock on the second side edge. In addition, the keyed interlock, which produces a characteristic noise, indicates to the user of the panels that an effective interlock has occurred.
