The invention relates to panels, especially floor panel with a core of wood material or a wood-plastic mixture, top side and bottom side, while the panel on at least two opposite lateral edges is corresponding to each other profiling that by essentially vertical connecting movement two identically made panels have the ability to connect with each other and mutual fixation in the horizontal direction and in the vertical direction, the fixation in the horizontal direction is carried out by means of a hook connection with the hook element of the upper fixing portion and having a hook element of the lower locking section, the locking in the vertical direction is carried out via at least one elastic element is arranged to move in a horizontal direction, at least one elastic element for joint movement is latched for passing essentially in the horizontal direction, the locking edge.
Panel locking in the vertical direction is known, for example, from EP 1650375
A1. This is implemented in this view panel fixing, preferably provided on a lateral side of the flooring panels. However, the fixation of which may also be provided on the longitudinal side or on the longitudinal, and on the lateral side. The elastic element is made of plastic, is inserted into the horizontal groove on one of the side edges and beveled on its upper side. Similarly, door latch, due to the bevel of the elastic element is pressed into the groove of a new subject for panel mounting, when its lower edge reaches the bevel and it goes on. When new, subject to stacking panel completely falls on the ground floor, the elastic element is snapped into the groove positioned horizontally in opposite lateral edge and captures both panels in the vertical direction. To make this elastic element necessary special tools for injection molding, so its production is relatively expensive. In addition, it is necessary to apply high-quality plastic to ensure a sufficient strength, which further increases the cost of the elastic element. If you are plastic too low in strength, this leads to a relatively large dimensional deviations of the elastic element, so as soon as this provides the ability to create or transfer the relevant efforts.
Due to the fact that the securing element is designed as a separate part, there are many other possible applications. Technology is key due the manufacture of the locking element is spatially separate from the panels, so that the integration in the continuous process of production, primarily for flooring panels, rather impossible. Because different materials - wood, on the one hand, and plastics, on the other hand, the alignment of the manufacturing tolerances of two separate manufacturing processes time-consuming and costly. Since the fixing in the vertical direction in the absence of the locking element would be ineffective, he shall, moreover, be secured from falling out located on the side edge of the groove in the further course of the production process and during transportation. This protection is also time-consuming. Alternatively, the locking element can be deliver to the consumer separately.
Increasingly, the sex of the panel in question, are placed by the owners themselves, so that, in principle, due to the lack of experience there is a possibility that will be incorrectly estimated the required number of locking elements and they will be purchased in sufficient quantity to completely put the whole room. Furthermore, we cannot exclude the possibility that the application of the elastic element owner make a mistake that will lead to the fact that the exact fixation is impossible is, and the connection will eventually disperse, then that mistake will be assigned by the user as supplied by the manufacturer of the products.
From DE 10224540 A1 famous panel at opposite side edges shaped so that the form is made in the form of hooks connecting elements for fixing the horizontal direction. For locking in the vertical direction on the connecting elements provided by the geometric elements of the circuit, arranged horizontally and vertically at a certain distance from each other, and the corresponding undercuts respectively with horizontally oriented locking surface. The transverse length of such horizontally oriented locking surfaces is about 0.05 to 1.0 mm For the connection of two panels remained at all possible, the sizes should be small. But this inevitably it turns out that can be perceived only small vertically directed force so that the production must be carried out with very small tolerances to ensure that the connection when the normal load is not disturbed even in light of the irregularities of the floor and/or soft floor basis.
In the unpublished application DE 102007015048.4 described panel, which is fixed in the vertical direction is carried out by rolling in a horizontal direction of the elastic element. When connecting the movement of the elastic element snaps over the locking edge, passing essentially in the horizontal direction. The elastic element is formed of horizontal and vertical cut from the core and on at least one of both of their ends connected to the core. Horizontal and vertical incision enables the springing movement of the elastic element necessary to obtain fixation. However, this fixation is not suitable for thinner panels with thickness from about 4 to 8 mm
Based on this identified the problems described above, the panel requires improvement.
To solve this task, the panel is of the specified type, characterized in that at least one elastic element (6) is formed from the core (3) is integral, and that the specified at least one elastic element is made on the lower locking section.
First of all, when this design greatly simplifies manufacture. There is no need to adjust the tolerances of the various parts. The manufacturing time and the manufacturing costs are reduced because you don't need to articulate and hold together the various parts. In addition, the end user is guaranteed that you will not encounter such situation that there is not enough detail, and the operation cannot be continued.
Another advantage is that the UAV is odara laying the elastic element on the lower fixing section also eliminates the need for horizontal groove to release the elastic element from the core. Due to this, the movable elastic element can have a greater vertical length, resulting in improved rigidity and structural strength of the panels. In addition, large relative to the thickness of the panel, the vertical length of the movable elastic element enables a more reliable connection of thin panels of a thickness of from about 4 to 8 mm
Preferably, at least one elastic element in the direction opposite lateral edges is free relative to the core, and in the direction of its side edges connected to the core on at least one of both of their ends, first and foremost, on both ends. In terms of the effective connection of the elastic element with the core you can adjust the elasticity of the elastic element.
The release of the elastic element with respect to the core is carried out, preferably, by essentially vertical groove. Due to the width of the groove can be defined binding force of the spring element to the core material, and to create emphasis in a horizontal direction to the elastic element, so that it is protected from pererasseyaniya.
According to the invention provides that essentially vertical groove at least partially performed through the lower locking section. Thus there is tsya in mind, that the groove does not necessarily have to be performed along the entire length of end-to-end, and can be done, especially in transition areas at their ends to form the slits. The slot in the transition region expedient way is open to the bottom side of the panel and is closed to the upper side of the panel. This allows for simple and inexpensive manufacture, since the panel can be moved through the milling tool at a constant speed and you only need to change the penetration depth of the milling tool in the toolbar. The transition region can be performed at one or both ends of the elastic element. The slot may have a varying depth, for example uniformly increasing depth.
Preferably, essentially vertical groove made in the field of a hook element of the lower locking section. In the field of a hook element fixing area expediently has a maximum vertical length, so that the elastic element in this area can be made correspondingly large vertical extent. With the increase in the vertical extent of the elastic element increases its rigidity.
If the length of side edges, a plurality of elastic elements arranged at a certain distance from each other, increases the stability of the connection, the AK as a restricted free springy move in the longitudinal direction of the elastic element. The distance between the individual elastic elements can be chosen more or less large. The smaller the distance, so, naturally, the more effective the surface that you are fixing, so that the transmitted power in the vertical direction are correspondingly large.
If the outer edge of the elastic element is inclined to the upper side under the (acute) angle, preferably at an angle from 40° to 50°, the connecting motion is facilitated, as the elastic element with increasing movement deeper sags in the direction of the core panel. In addition, it reduces the risk of damage to the elastic element in the process of connecting traffic.
The hook element on the upper fixing section preferably is formed by a ledge made towards the lower side of the panel. The hook element on the lower fixing section preferably is formed by a ledge made in the direction of the upper side of the panel.
The configuration of the elastic element according to the invention is particularly suitable for thin panels. Under a thin panel refers to a panel thickness of approximately 4 mm to 8 mm, Preferably selected thickness of about 7 mm or about 8 mm
Using the drawing describes the following examples of implementation of the invention.
Figure 1: top view of the two interconnected panels
2, 3, 4, 5: both panels of figure 1 in partial section in four consecutive time in the process of connecting traffic.
Figure 1 shows two panels 1, 2. In the top pane of figure 1 shows a section along the line a-a in the lower pane of figure 1.
Panels 1, 2 are made identical. They consist of a core 3 of wood material or a wood-plastic mixture. At its opposite side edges I, II panel 1, 2 shaped, with the lateral edge I from the bottom side 4 and the side edge II top 5 were processed by milling.
On the side edge 2 has three elastic element 6. Elastic elements 6 are identical, so the next example describes one of the elastic elements 6. However, the elastic elements 6 does not necessarily have to be made identical.
The elastic element 6 was obtained free milling core 3, which was milled essentially vertically passing through the groove 7 with the ends 7a, 7b. The side edges I, II have a length L. In the longitudinal direction of the side edge II of the elastic element 6 at the ends 6A, 6b connected to the core material. The release of the elastic element 6 of the core 3 is exclusively through the slot 7. The outer edge 6C of the elastic element 6 is inclined toward the upper side 5 of the panel at an angle α. Vertical surface Boko what's edges I, II processed so that the upper face 5 formed surfaces 8, 9 of the fit.
On the opposite the elastic element 6 side edge 1 panel 1 has extending essentially in the horizontal direction H of the groove 10. The groove 10 extends along the entire length L of the side edges I. However, it would be enough to provide a sufficiently long grooves 10 on the respective elastic elements 6 sites along a lateral edge I. the Top wall 11 of the groove 10 forms an essentially horizontal locking edge. From the figures it is clear that the base 12 of the groove 10 is held essentially parallel to the outer edge 6C of the elastic element 6, which facilitates the manufacture of the groove 10. However, it could be performed in a vertical direction or at an angle different from the angle α.
Fixation of the two panels 1, 2 in the horizontal direction occurs with krukovich elements 13, 14, obtained by milling with a stepped profile. The hook element 13 is part of the upper fixing section 15. The hook element 14 is part of the lower base section 16.
The hook element 13 is held in the direction of the lower side of the stepped ledge 17 of two stages 18a, 18b. The hook element 14 has extending in the direction of the upper side of the stepped ledge 19 of two stages 20A, 20b. Step 18a and eat essentially flat support surface 21, which interacts with an essentially horizontal support surface 22 of the stage 20A hook element 14. Support surfaces 21, 22 form an essentially horizontal plane E (figure 5), so that the United panels 1, 2 are based on each other.
Profiling krukovich elements 13, 14 is selected so that the junction is created pretensioning and vertical surfaces 8, 9 of the fit of the panels 1, 2 are pressed to each other, so that on the upper side 5 is not formed any visible cuts. To facilitate connection of the panels 1, 2 step ledge 13 of the upper fixing section 15 and a stepped ledge 14 of the lower locking section 16 at its edges beveled or rounded.
The figure 1 show the six transition regions 23. Two transitional region 23 are located at the ends 7a, 7b of the groove 7, and they essentially mirror-symmetrical with respect to line a-A. In this example, the transition region 23 is made in the form of slots with essentially uniformly decreasing depths (figures not shown). When this transition region 23 has the greatest depth at the end facing the groove 7, and the minimum depth at one end, which leads to the lower side of the panel 2.
Figure 2 is visible protrusion 24 of the panel 1. The protrusion 24 is directed essentially horizontally in the direction of the panel 2. The protrusion 24 has sections is laskow edge 25, which at the lower section runs at an angle (to the upper side, in the middle part essentially vertically, and the upper section 26 is essentially horizontal. The upper portion 26 forms a wall of the groove 10. In the top view of the protrusion 24 has a beveled edge 26a (1) to reduce the risk of damage during fixation of the panels 1, 2.
In the process of connecting the movement of the elastic element 6 is horizontally offset in a result of colliding with the protrusion 24 in the direction of the groove 7. At this offset because of the connection with the core 3 at the ends of the elastic element 6 occurs the tension. The width of the groove decreases. This tension causes the elastic element on the last section of the connecting movement (figure 5) snap into place in the groove, i.e. the elastic element 6 is horizontally shifted in the direction of the grooves 10. The horizontal offset is in the form of elastic recoil in the appropriate position under the influence of internal tension. The width of the groove increases again. The groove 10 has such dimensions that the elastic element 6 can occupy its original position. Groove zarezerwowana in the core 3 is slightly deeper than would be required for installation of the elastic element 6. This facilitates the laying of the panels 1, 2.
The groove has a height of about 60% of the thickness of the panel. This allows you to apply fixation according to the invention in vertical the MD direction and in the case of thin panels of a thickness of approximately 4-8 mm However, locking in the vertical direction according to the invention can also preferably be implemented in the case of thicker panels, for example a thickness of about 12 mm
From figure 5 it is clear that when stacked the panels 1, 2 in the side edges I, II are provided free spaces 27A, 27b, 27C, 27d. These free spaces 27A, 27b, 27C, 27d provide the necessary styling freedom of movement and compensate for any manufacturing tolerances.
The release of the elastic element 6 through the vertical groove is provided with a tool, move across the direction of processing. When this processing is preferably carried out in continuous mode, so that at the beginning and at the end of the groove 7 is formed in the transition region 23.
As tools can be used milling machines, laser or water-jet tool or the vertical blade or pulling. Presented at the shapes example implementation requires only one shifting tool. When processing is reduced nonliberalized region, which as a whole (integral) connects the elastic element 6 with the core. This allows you to install different size retention efforts. In this example implementation, the detent is releasable by the fact that the panels 1, 2 slip relative is about each other along the side edges I, II or that side in place of compound injected not shown deblocare pin.
