Definitions

  • the invention relates to a method for producing interconnectable components as well as an arrangement of components with connecting elements according to the preamble of claim 2.
  • plate-shaped components for example panel panels, floor panels, cladding panels, trim strips or the like are understood in particular for the wall-ceiling or floor cladding of buildings of all kinds.
  • Such components may be single or multilayer boards or strips of wood-based or wood-based (laminates), in particular chipboard, MDF, HDF, OSB, hardboard or plywood panels, which may be coated on one or both outer surfaces ,
  • the coating, the so-called wear layer can be done with plastic plates, solid wood, veneers made of wood or plastic or paper, etc.
  • the invention particularly relates to the specific type of training and Manufacture of the components and the connecting elements in order to hold the components in an interconnected state optimally in position, but to be able to solve the components from each other if necessary.
  • the protruding beyond at least one side edge of the panel spring is particularly susceptible to damage, since they can strike particularly hard against obstacles because of their small cross-section and the great weight of a panel. This applies to the manufacture, transport and installation. Also prone to the groove, since the panel has a reduced wall thickness in the region of the groove. The outer walls of the groove may even be thinner than the cross section of the spring.
  • Damaged springs or those made of water-permeable or water-absorbing material also make the tongue and groove joint more permeable to water. Spilled water on the joint therefore penetrates more easily into the frequently liquid-absorbing middle layers (core) of the panel, which therefore swells and becomes unsightly. The moisture can also penetrate through the tongue and groove connection and hold on the underside of the panels for a long time. This moisture evades the observation or elimination and can cause the long-term typical for moisture damages, such as mold, bacteria, efflorescence, leaching.
  • EP 1 024 234 discloses such panels with a tongue and groove connection, wherein locking means are provided for locking on the grooves and springs. Since the grooves and springs, together with the locking means, are milled integrally from the core made of HDF or MDF, the strength properties of the grooves and springs are determined by the material properties of the core of the panel. Therefore, the core of the panel is harder, stronger, heavier and more expensive than necessary for a floor covering, for example, in view of the strength of the connecting and locking means necessary for secure connection.
  • US 5,295,341 discloses panels in which the fasteners are strip-like connected to the edges of the panels, so that the materials for panels and Vietnamesesungsmittel- can be optimized respectively.
  • hook-like anchors are formed on the connecting strips, which engage in undercuts in the panels. Such geometry with undercuts is very expensive to manufacture.
  • WO-A-00/20706 and WO-A-00/20705 disclose floor panels which can be interconnected via separate connection profiles by moving the longitudinal edges horizontally toward one another or by vertically lowering the longitudinal edges.
  • the connecting means must therefore on both sides, ie with the longitudinal edges of two profiles to be connected, lock. This increases the Hersfiellungsierwand, as the factory on a longitudinal side of a profile, the separate connection means must be attached. Otherwise, the effort for the installer on site increases, as this immediately before Assembly the connecting means must first connect on one side with a panel and later on the other side with the panel to be connected, the connecting means are therefore not firmly connected on both sides with the panel, so that the risk of unlocking doubles and the connection less rigid and firm. In addition, more processing steps per connection must be made, namely for two springs and two grooves. To make a connection usually a groove and a spring are sufficient
  • each panel has a spring which is coated with a foreign material. By this foreign material locking elements are formed, which allow the positive connection.
  • the invention provides an arrangement of connecting means, in particular einschnappbare connecting means, connectable components.
  • the spring is made of a different material as the respective component with which the spring is permanently connected, it is possible for both the components and the springs in terms of requirement and cost to select optimal materials independently, the manufacturing cost reduces, since only a groove and a spring, which are necessary for releasable connection, must be made.
  • the connecting means may for example consist of PVC, plastics and the like, which is harder than the core of the panels and produced on a special milling machine (eg pencil milling machine).
  • a special milling machine eg pencil milling machine
  • the particularly heavy and / or stable material is only processed at the point where it is actually needed, while the core of the panel is made of lighter and cheaper material.
  • the weight of the panels is a significant economic factor as it affects the cost of transportation and the price of the product, as well as consumer acceptance. Consequently, there is a high potential for savings in that one equips only the positive or high-viscosity part with high mechanical strength.
  • the connecting means in the form of a spring made of a different material than the respective component is inextricably connected to the respective associated component, errors during assembly are avoided.
  • the connecting means can not slip or displace along the longitudinal side, and liquid which gets into the joint of two components is prevented from penetrating deeper into the component or from getting under the component and causing further damage there.
  • Such an insoluble compound can be achieved in particular by positive locking.
  • positive locking is particularly economical manufacturable and very firm when the connecting means are brought in the liquid or soft state with the respective component in contact.
  • the liquid bonding agent penetrates into openings and pores of the component, so that there is a connection by positive locking. Similar strength can be achieved by gluing.
  • the form-fit succeeds particularly effective when the still liquid or which connecting means in grooves with or without Schuschnehlen of the component, in particular along the front or longitudinal side of a plate-shaped member is introduced.
  • Grooves without undercuts are particularly easy and fast, for example, coming from the front over the entire length of the front page to manufacture. Grooves with undercuts are more expensive to manufacture, but keep the introduced therein fasteners particularly strong.
  • the inner contour of the grooves can also be shaped differently, for example by milling, breaking or inaccurate methods. This makes the machining easier, cheaper and faster and the strength of the seat increases. On very precise editing tools can therefore be dispensed with.
  • the components can be assembled more easily.
  • a projecting leg on the underside of a component can in fact serve as a guide when the components move toward each other.
  • connection means are unequal in shape, that is to say projecting, a higher load capacity of the connection means in the direction of the projecting leg results.
  • a protruding leg on the underside of a component can, for example, intercept the loads occurring when entering the component.
  • the connecting means is made of extrudate, which can be brought into contact with the component in the still soft state when leaving the extruder in order to connect to this.
  • Extrudates are usually molded parts produced by means of an extruder. While such moldings normally initially harden in their final form before intermingling with other components be connected, it is advantageously provided to connect them in the still soft or liquid state with the component. In this case, it is not necessary for the extruder to have a specific profile. Rather, it is important that the liquid or which extrudate is introduced into the groove of a component, and connects with this by filling. If the front side, d. h the longitudinal or transverse side of the component, in which the groove is introduced, is horizontal, the extrudate can flow down into the groove, with an excess of material accumulates on the front side, without forming a well-defined profile. This is rather the task of the subsequent processing step.
  • An extruder in the sense of the invention can therefore also be a device from which a material which has not yet been completely hardened can escape in a controlled manner, without the extruder giving it a concrete shape.
  • the mold is adapted to the final shape in order to remove less material during finishing.
  • connection is releasable if, on the one hand, it is so strong that it can not be unintentionally released and, on the other hand, it can be released again non-destructively if necessary. In relation to floor panels, this means that laid and interconnected panels are in use, i. Entering the floor and moving loads on the floor, do not accidentally break loose.
  • the connection should, if necessary, for example, in laying errors, repairs and disassembly, be easily solvable, for example, by the fact that the two components are removed from each other in the plane spanned by them or pulled apart. Supportive or alternatively is understood by a releasable locking and such, in which the individual components can be solved by twisting or tilting back in case of need.
  • a particularly strong and inexpensive connection succeeds when the connecting means have the ability to foam and therefore completely fill the groove (filling groove) of the component intended for filling, whereby the contact surface between the connecting means and the filling groove increased.
  • the introduction of the extrudate into the filling groove is therefore carried out in one operation with the floor production, which costs can be saved.
  • the non-detachable connection means connected to the component also has the advantage that in the finishing, for example, the milling of a groove or spring, the connecting means can not slip and already have their final position.
  • the groove or spring is formed more accurate and more accurate. This allows the components to be connected to each other in a simpler, stronger and safer way. This is not the case when using a fully formed spring, which is then firmly connected to the component
  • Snapping is when a positive connection is made by elastic members which give way upon joining, e.g. the spreading groove legs, or a compressible spring, so-called snap-in connections are particularly easy and safe to produce for the user, and particularly accurate.
  • the connecting means can be produced if their maximum thickness is at the same time the maximum thickness of the springs.
  • the flat lower surface of the panels has a positive effect on the appearance, is easier to produce than a contoured lower surface and absorbs impact noise, since cavities are avoided.
  • Coated top and bottom surfaces make the surface less sensitive to scratching, denting, moisture and provide an attractive appearance.
  • the joining or separation of the thus formed connecting means is gentle to the material, quickly and reliably, although it is ensured that the panels are held optimally in position in the connected state.
  • the groove is worked out of the component directly, in particular milled out, whereby the production of such panels is facilitated.
  • the two legs of the groove are substantially the same length except for minor differences in length, which can be provided that the components are close to each other in their near-surface region and are spaced from each other in the near-bottom regions to form a small gap. This ensures a safe juxtaposition of the two tops of the panels even with certain unevenness of the ground.
  • Such fabricated panels may also be combined with existing one-piece spring or groove milled out of the core, thereby providing some downward compatibility of the product of the invention with known products , This opens up further fields of application and the system can be used more flexibly.
  • the width of the groove which increases from the inside to the outside or the thickness of the spring, which decreases toward its free end, are matched to each other, so that in interconnected components, the tongue and the spring surfaces fed, i. lie positively against each other. This keeps the components in a defined mutual position.
  • the locking elements provided for the positionally fixed connection of the components which are formed by mutually adapted projections and recesses, are provided on the groove and on the spring. These locking elements may be provided in sections on the groove and the spring; However, better grip and simplified manufacture is achieved when these become Extend locking elements over the entire length of the intended grooves and springs.
  • An embodiment of the arrangement according to the invention is particularly advantageous, in which on both sides of the spring corresponding projections and on both groove surfaces corresponding recesses are formed, since thus a double locking effect can be achieved and thus a firm cohesion of the components is achieved.
  • the width of the components can be chosen arbitrarily. Components of the same width or components of different widths can be connected to each other, e.g. to achieve a certain floor design.
  • a preferred embodiment of the invention is characterized in claim 16.
  • This cross-sectional shape of a spring with at least one projection located thereon and at least one correspondingly adapted recess in the groove allows a good sliding of the surfaces of the spring or of the projection carried by the spring on the groove surfaces or directly adjacent to the groove opening groove surfaces during insertion of the Spring in the groove.
  • the component in particular an MDF / HDF plate is milled on the longitudinal and / or transverse sides and then provided in the resulting groove with extrudates. Subsequently, the free ends of the extrudates are milled out, so that they form spring profiles. Alternatively, however, a groove can also be milled from the extrudates.
  • a profiling of a rapidly solidifying extrudate can also be made during the extrusion process already a corresponding profiling of a rapidly solidifying extrudate and thus time and material and costs are saved.
  • the profiling can be done, for example, reshaping or cutting.
  • a corresponding one-part method can be realized.
  • plastic as an extrudate is preferred because it can be milled most accurately.
  • the advantage of the invention to the prior art is, inter alia, that the introduction of the extrudate in one operation with the Manufacture of components can be made, the profiles have a very firm grip with the core material, the profiles can be milled much sharper and thus lockable when using plastic, the extrudates are inexpensive materials, an elastic property of the grooves or springs regardless of the material properties of Core material is given and you can do without a sealing of the connecting surfaces, as is reduced or prevented by the extrudates or the plastic, the water and moisture absorption.
  • the extrudate can also extend to the surface of one or both components. It thus forms mechanically and optically an intermediate piece along the edges of the components. It thus fulfills a dual function, namely it serves as a connecting means and moreover fulfills aesthetic, protective and stabilizing functions, wherein it is not mandatory for the purposes of the invention that the extrudate also serves as a connecting means.
  • edges of wood-based materials are usually in the area of the impact-prone surface particularly often with Aufstiffept, ie upwardly facing breaks provided.
  • Aufstiffept arise but also when editing the edges and are insbesöndere in laid panels, along the edges in the backlight easy to see.
  • the invention reaching to the surface Extrudate is able to avoid or cover these edges.
  • the component which is usually moisture absorbent, is protected from soaking up water. Moisture is known to cause swelling, which makes the component unsightly. An otherwise usual for this reason edge impregnation is unnecessary.
  • extrudate acting as an intermediate piece can be produced in a wide variety of materials, structures and colors. Such interlacings therefore form, especially when they are colored, particularly decorative elements and influence the look of precious to rustic.
