Description

[0001] Longitudinal connection

[0002] The invention relates to an arrangement comprising at least one first, preferably plate-shaped, component, at least one further, preferably plate-shaped, component, and at least one, preferably planar, spring with a longitudinal extension, wherein the at least one first component and the at least one further component each have at least one groove on an end face for providing a tongue-and-groove connection. The invention further relates to a plate-shaped spring made of wood or wood-like material and to a wooden plate as a component for such an arrangement. The invention also relates to a method for assembling such an arrangement.

[0003] Traditionally, in state of the art, building components are secured against transverse forces by means of dowels and against longitudinal forces relative to each other by means of screw connections or glue connections.

[0004] To replace screw connections as additional component parts, glued joints can be used, thus ensuring a more neutral appearance of the assembly. From an ecological perspective and in connection with ease of assembly, there is a need in the construction industry, among carpenters and joiners, as well as in the furniture industry (especially among manufacturers and suppliers of component parts) to replace glued joints – for example, to enable the recycling of component parts.

[0005] A tongue-and-groove joint is already known from document RO 115510 Bl. Geometrically machined wooden panels are known from documents US 3, 623, 261 A and FR 2861413 Al. Wooden joints using lamellae and dowels are known from documents US 10, 151, 101 B2 and JP Hl- 136447 A.

[0006] The objective technical object of the present invention is therefore to provide an improved arrangement compared to the prior art, a spring, a wooden plate and a method, which are characterized in particular by an achievable longitudinal connection in which glue and screws can be dispensed with.

[0007] This problem is solved by the features of claim 1.

[0008] It is therefore provided according to the invention that the at least one first component and the at least one further component are arranged end-to-end adjacent to each other, preferably essentially without joints, and that the at least one spring is arranged at least partially within opposing grooves of the at least two grooves, the at least one spring comprising an outer contour with a plurality of maxima spaced apart from each other along its longitudinal extent, preferably arranged periodically, wherein the maxima are oriented orthogonally to the end face of the at least one first component and the at least one further component, and the at least two grooves each have a geometry corresponding to the outer contour of the at least one spring.so that a longitudinal connection between the at least one first component and the at least one further component is or can be produced by positive locking in the longitudinal direction along the end faces.

[0009] This makes it possible to fix the two components longitudinally using at least one spring, without the need for glue, dowels, screws, adhesives, or other securing devices. Furthermore, the spring and both components can be recycled particularly efficiently.

[0010] As stated at the outset, protection is also sought for a plate-shaped spring made of wood or wood-like material for such an arrangement with a longitudinal extent and at least one outer contour, characterized in that the at least one outer contour comprises a plurality of periodically arranged maxima along the longitudinal extent, wherein the at least one outer contour is wave-shaped and extends over two sides of the spring.

[0011] This geometry has proven particularly advantageous for a stable and strong longitudinal joint. Wood or thin wood-based materials exhibit especially favorable material properties with regard to longitudinal joints – for example, a pressed thin wood-based material with additives can generally be used.

[0012] As stated at the outset, protection is also sought for a wooden panel as a building element for such an arrangement with at least one end-face groove, characterized in that the at least one groove comprises a plurality of periodically arranged minima in wave form along at least one end face of the wooden panel.

[0013] For example, carpenters can use such a wooden panel to carry out residential / house construction more efficiently and avoid using materials that are particularly environmentally unfriendly. The wooden panel preferably has a thickness between 15 mm and 40 mm, with a thickness of essentially 20 mm being particularly preferred.

[0014] As stated at the outset, protection is also sought for a method of assembling such an arrangement, wherein the following process steps are carried out:

[0015] - at least one first component and at least one further component are provided by milling the at least one groove into their respective end faces, and at least one tongue is provided by milling the outer contour corresponding to the at least two grooves and

[0016] - the at least one first component and the at least one further component are connected to each other by the at least one spring at their end faces adjacent to each other, preferably essentially without joints, so that the longitudinal connection is made by positive locking in the longitudinal direction via the at least one spring.

[0017] This allows for the creation of a stable longitudinal joint with a small number of process steps and, in particular, quickly, without the need for adhesives or glues to cure. The installer does not require any screws or fasteners for the longitudinal joint.

[0018] Advantageous embodiments of the invention are defined in the dependent claims.

[0019] According to an advantageous embodiment of the invention, the longitudinal joint is designed to be free of adhesives, preferably free of glue.

[0020] Advantageously, the outer contour of the at least one spring is designed in a preferably continuous, wave-like shape, preferably sinusoidal or triangular shape, and / or has an amplitude between maximum and an adjacent minimum of between 5 mm and 50 mm, preferably with a residual material thickness of at least 3 mm.

[0021] By using a wave-like geometry and / or an amplitude in the range between 5 mm and 50 mm, a particularly favorable support situation can be ensured, whereby it can be ensured that a particularly large surface area / contour is involved in the longitudinal connection through elastic and / or plastic deformation.

[0022] It has proven advantageous that two outer contours arranged on opposite sides of the at least one spring are essentially mirror-symmetrical or mirror-symmetrical with a half period offset on the at least one spring.

[0023] This allows for a positive fit between both components via the same spring. If there is an offset between opposing maxima, the residual material thickness between the two opposing outer contours can be increased, although this is not strictly necessary. A mirror-symmetrical design of the outer contours is particularly preferred.

[0024] According to an advantageous embodiment of the invention, the at least one spring has a thickness between 3 mm and 10 mm, preferably between 4 mm and 6 mm, and / or a width between 10 mm and 100 mm, preferably between 20 mm and 60 mm, and / or a longitudinal extent in the range of 30 cm to 300 cm, preferably from 50 cm to 150 cm. These dimensions have proven particularly advantageous with regard to wooden panels, and the number of springs can optionally be doubled or multiplied to effectively increase bending stability in thick components.

[0025] For example, an unpressed spring has a width of 25 mm, which widens to 27 mm during a pressing process. A pressing process can, for example, take place in a mold, although mold-free pressing is preferred.

[0026] It has proven advantageous that two maxima adjacent along the longitudinal extent, preferably all adjacent maxima of the outer contour each, are spaced between 50 mm and 100 mm apart.

[0027] This shape allows for the machining of components and / or at least one spring to be carried out comfortably - especially while protecting the material being machined and / or with high strength in the longitudinal connection.

[0028] An advantageous variant consists in the fact that the at least one spring and / or the at least one first and / or the at least one further component consists at least predominantly of wood or wood-like material, wherein it is preferably provided that the at least one first and / or the at least one further component is a wooden plate, wherein a minimum plate thickness is 20 mm and / or a maximum plate thickness is 200 mm.

[0029] In general, however, it is also conceivable to use plastic, plastic-like materials (for example, fiber-reinforced materials), or metallic materials. Preferably, at least two superimposed, preferably parallel to each other or forming an angle, and spatially spaced-apart springs and grooves are provided for each longitudinal connection in a plane parallel to the end face of the at least one first component and the at least one further component, wherein it is preferably provided that the at least two springs are arranged in an edge region of the at least one first component and / or the at least one further component, particularly preferably with a residual material thickness of at least 5 mm.

[0030] By using at least two springs arranged vertically offset from each other in the state of use, bending stability can be significantly increased, thereby inhibiting the risk of breakage in the longitudinal connection.

[0031] Preferably, two springs arranged one above the other are offset relative to each other by half a period, so that a maximum of one spring is located above a minimum of the other spring.

[0032] This can increase bending strength - for example in S-shaped springs and / or in mirror-symmetrical springs.

[0033] In one embodiment of the invention, it is provided that a plurality of springs are arranged sequentially in series per longitudinal connection and / or that a plurality of components arranged in series are connected per spring.

[0034] It is particularly preferred that at least one locking means, preferably a dowel, shear pin or clamp, is provided with which the at least one spring can be secured or locked in a direction orthogonal to the longitudinal direction by means of a positive locking mechanism, wherein it is preferably provided that the at least one locking means can be inserted or introduced orthogonally over a plane onto the end face of the at least one first component and the at least one further component, particularly preferably without adhesive and / or via an interference fit, and / or a plurality of locking means are arranged in pairs on the at least one first component and the at least one further component.

[0035] A dowel, for example, can be removed to release the transverse locking mechanism during use. Generally, transverse locking can be achieved, for example, by means of a clamping connection, frictional engagement, and / or other connecting devices. This at least one locking device prevents an undesirably wide gap from forming between the two components or from the two components separating orthogonally to their longitudinal axis (for example, if the components are not clamped on the outside).

[0036] According to a preferred embodiment of the invention, the at least one locking means is arranged in a bore, preferably one-sided, which at least partially penetrates the at least one first component or the at least one further component and the at least one spring, and / or is visible exclusively on one surface of the arrangement in the state of use.

[0037] The at least one securing device can stabilize the at least one component relative to the at least one spring. If the at least one securing device is inserted on only one side, a particularly neutral visible surface can be provided, whereby generally visible securing devices can be used as an aesthetic decorative element.

[0038] It has proven advantageous that the at least one spring can be secured or secured within the at least two grooves in one direction orthogonal to the longitudinal direction by means of a force fit and / or an interference fit, preferably by a clamping connection.

[0039] This eliminates the need for securing devices for transverse fixing, although securing devices can generally be used as a supplement.

[0040] Furthermore, it is preferably provided that the at least one spring is pressed to a reduced thickness before being inserted into at least one of the at least two grooves, preferably using liquid or moisture, wherein it is preferably provided that the thickness of the at least one spring is compressed by a range between 0.5 mm and 2 mm, particularly preferably by substantially 1 mm and / or 20%, during the pressing process.

[0041] Following the pressing process, at least one spring can expand from a reduced thickness to an increased thickness in order to exert pressure on the respective component.

[0042] Preferably, at least one spring is provided and / or supplied for use in a dried and / or compressed state.

[0043] In a preferred embodiment, liquid or moisture is introduced through at least one dowel hole and / or bore. This allows both the spring and the dowel to swell, ensuring a particularly strong and secure longitudinal connection. The addition of liquid or moisture can occur before or after the insertion process of the at least one spring, whereby, for example, a dry spring can be inserted and subsequently moistened. Adding liquid or moisture for swelling—preferably after a pressing operation, if applicable—is generally not strictly necessary, as the at least one spring can be inserted, for example, by means of a clearance fit or an interference fit.

[0044] In another embodiment, it can be provided that the at least one spring is pressed into at least one of the at least two grooves during the insertion of the at least one spring, preferably by means of an inclined surface that partially reduces the thickness of the at least one spring, or subsequently after the insertion of the at least one spring into at least one of the at least two grooves, to clamp the at least one spring in the at least one of the at least two grooves, wherein it is preferably provided that liquid or moisture is introduced into the at least one of the at least two grooves and / or the at least one spring and / or applied to the at least one spring and / or to the at least one first component and / or the at least one further component, particularly preferably in the area of ​​the at least one groove.

[0045] A press-fit operation ensures a particularly strong longitudinal connection, guaranteeing that the at least one spring remains securely positioned between the two components. According to an advantageous embodiment of the invention, a subsequent process step involves inserting at least one locking element for fixing the at least one spring orthogonally to the longitudinal extent of the end face of the at least one first component and the at least one further component, preferably through a bore and / or exclusively via one side of the at least one first component or the at least one further component. It is preferably provided that the at least one locking element is cut to length, preferably exclusively on one side.

[0058] Fig. 1b schematically illustrates alternative outer contours 8, wherein in the upper representation an outer contour 8 in triangular form 15 is shown and in the lower representation a wave-shaped outer contour 8 with half a period length (this is generally arbitrarily selectable) in comparison to the outer contour 8 in Fig. 1a.

[0059] If two outer contours 8 are provided on opposite sides of the spring 3, it is preferred that these are designed to be essentially mirror-symmetrical or mirror-symmetrical with a half period offset on the spring 3.

[0060] Fig. 2 shows a spring 3 arranged in a region within a first component 1 for a longitudinal connection 11 or as a tongue-and-groove connection 7 .

[0061] For securing in the transverse direction, a large number of securing devices 22 in the form of dowels 23 as shear pins are provided, with which the spring 3 can be fixed orthogonally to the longitudinal direction 12 by means of a positive locking mechanism.

[0062] The locking means 22 are inserted orthogonally on the end face 5 of the first component 1 via a plane without adhesive and via an interference fit, wherein it is provided that the plurality of locking means 22 are arranged in pairs on the first component 1 and a further component 2 which is yet to be connected.

[0063] The locking means 22 are inserted into a one-sided bore 24 of the arrangement which penetrates at least partially the first component 1 and the spring 3, wherein the locking means 22 are visible in the operating state of the arrangement only on a surface 25 of the arrangement (this is not necessarily intended).

[0064] The outer contour 8 of the spring 3 comprises a plurality of maxima 9 spaced apart from one another along the longitudinal extent 4 and arranged periodically, wherein the maxima 9 are oriented orthogonally to the end face 5 of the first component 1.

[0065] Fig. 3 shows a longitudinal connection 11 in the form of a tongue-and-groove connection 7 in a perspective view, where it can be seen that the first component 1 (and the at least one further component 2 in an analogous manner) has a groove 6 on an end face 5 to provide a tongue-and-groove connection 7, wherein in this embodiment two grooves 6 are provided for two springs 3 to increase bending stiffness.

[0066] The longitudinal connection 11 is designed without adhesives, glue, or screw connections.

[0067] The two grooves 6 each have a geometry 10 corresponding to the outer contour 8 of the associated spring 3. In general, differently designed springs 3 can be used per arrangement, with identical springs 3 per arrangement being preferred.

[0068] The first component 1 is designed as a wooden plate 21, wherein the wooden plate 21 has two end-face grooves 6 and the two grooves 6 each comprise a plurality of periodically arranged minima 17 in wave form 13 along the end face 5 of the wooden plate 21.

[0069] Each pair of adjacent maxima 9 of the outer contour 8 along the longitudinal extent 4 are spaced apart from each other by between 50 mm and 100 mm.

[0070] The spring 3 and the first component 1 are provided at least predominantly from wood or wood-like material, wherein the first component 1 is a wooden plate 21 with a minimum plate thickness of 20 mm and a maximum plate thickness of 200 mm.

[0071] In a plane parallel to the front face 5 of the first component

[0072] 1 Two superimposed, parallel, and spatially spaced springs 3 and grooves 6 are provided for each longitudinal connection 11. The longitudinal connection 11 is considered here to be the connection between the two components 1, 2, whereby the connection can also be considered as a connection comprising two longitudinal connections 11.

[0073] The two springs 3 are located in an edge area of ​​the components 1 ,

[0074] 2 with a residual material thickness 18 of at least 5 mm. The spacing between the rows of springs 3 can be adjusted according to the requirements of the arrangement.

[0075] In general, a large number of springs can be used per longitudinal connection 11.

[0076] 3 are provided sequentially in series. A large number of components 1, 2 arranged in series can generally be connected to each spring 3.

[0077] The at least one spring 3 is secured against slipping by means of a force-fit connection in the form of a clamping connection, wherein locking means 22 are preferably used for a particularly rigid connection in one direction orthogonal to the longitudinal direction 12.

[0078] Fig. 4 shows the arrangement with both components 1 and 2, wherein the first component 1 and the further component 2 are arranged end-to-end adjacent to each other, essentially without joints, and the two springs 3 are each arranged halfway within opposing grooves 6 of the two grooves 6 per component 1, 2. The springs 3 create a longitudinal connection 11 between the first component 1 and the further component 2 via a positive fit in the longitudinal direction 12 along the end faces 5.

[0079] An exemplary method for assembling the arrangement can be explained as follows: The first component 1 and the further component 2 are provided by milling grooves 6 into their respective end faces, and the springs 3 are provided by milling the outer contours 8 corresponding to the grooves 6. Subsequently, the first component 1 and the further component 2 are joined end faces by the springs 3, either without a joint or with the desired joint, so that the longitudinal connection 11 is formed by positive locking in the longitudinal direction 12 via the

[0080] Springs 3 are manufactured.

[0081] The springs 3 can be pressed to a reduced thickness 19 before being inserted into the grooves 6 by applying liquid or moisture, whereby the thickness 19 of the springs 3 decreases by 0.5 mm to 2 mm or by any percentage range during the pressing process.

[0082] The springs 3 can be pressed into the grooves 6 during their insertion - for example via an inclined surface - or subsequently after their insertion into the grooves 6 to clamp them, whereby liquid or moisture can be applied to the grooves 6, the springs 3 or the components 1, 2.

[0083] In a subsequent process step, any protruding material of the (one-sided) securing device 22 can be cut off (one-sided).

[0084] Fig. 5 shows an alternative outer contour 8 compared to the outer contour 8 in Fig. 1a, in that the two opposing outer contours 8 are offset by half a period length, resulting in a continuous S-geometry with essentially constant material thickness.
