Description

The invention relates to node connections with horizontal elements and vertical elements and shelving systems with such node connections, which are used for example in the furniture sector.

Under horizontal elements are, preferably plate-shaped, understood elements that in the mounted state preferably have upwardly and / or downwardly facing side surfaces, for example, massive shelves.

Under vertical elements are, preferably plate-shaped, understood elements that in the mounted state preferably have upwardly and / or downwardly facing end faces, for example side boards or columns.

Panel-shaped elements for furniture construction can be made, for example, from solid wood, from laminated wood, from plywood, from MDF or from a framework construction. It may be provided a wood veneer, a plastic veneer, a synthetic resin coating or a synthetic resin coating.

The node connection serves to connect horizontal elements and vertical elements, wherein in the limit case a vertical element is connected to a horizontal element. However, a node connection can also connect two horizontal elements with one vertical element or two horizontal elements with two vertical elements.

Various node connections for furniture construction are known from the prior art. These can be fixed, for example, with a non-positive and / or positive connection of the horizontal and vertical elements to be connected, with a gluing or with connecting elements. A variety of connecting elements are known in the art, which are based for example on a pure dowel connection or a screw-clamp combination.

When constructing a shelving system, for example, prefabricated or prefabricated modules can be interconnected. Each module can have its own node connections, which lead to a material doubling in the construction of a shelving system. This is aesthetically unattractive. The modular design requires a large number of individual parts and connecting elements. In addition, the modular design leads to superfluous multiple joints.

Alternatively, shelving systems can be constructed from individual parts, which can usually be expanded only in a horizontal or only vertical direction and in which predefined construction dimensions are given. Often long items are needed, for example, side walls, floor or cover plates, which has a disadvantage in the pack size. In systems with smaller plate parts and individual structure dimension usually additional fasteners and, accordingly, tools for mounting are needed. In addition, the fasteners often remain visible.

DE 20 2011 102 601 proposes a shelving system in which connecting sides of plate elements have profilings that overlap and / or intermesh with one another at the connecting surfaces by at least one material thickness, wherein the connection is achieved by the intermeshing of the overlapping profiling and / or the recess in the merging surface sections.

At the node junctions, the plate elements overlap, which means a material doubling. The surfaces of adjacent side by side and one above the other lying plate elements are not aligned, so that no uniform grid dimension is present.

DE 20 2007 011 071 also proposes a node connection in which the plate elements have profiles, but are connected to a node connector, which is inserted from the front and / or rear side and therefore visible in the assembled state.

The object of the present invention is to overcome the disadvantages of the known and to present a stable, cost and low-production, easy to install and detachable node connection and a shelving system with such node connections.

The object is achieved by a node connection for connecting preferably horizontally and vertically arranged elements, which comprises at least one plate-shaped horizontal element and at least one vertical element with the features of independent claim 1.

The vertical element has in particular a downward and an upward facing end face. The vertical element may be of columnar design, for example cylindrical or prism-shaped, with angular or rounded end faces. Preferably, the vertical element is plate-shaped and has rectangular end faces with a shorter and a longer side. The end faces are the surfaces of the vertical element, which preferably point upwards or downwards in the assembled state, are preferably arranged horizontally in the mounted state, and as a bearing surface for a horizontal element serve. The vertical element has a width, a height and a depth relative to its extent in the mounted state. The faces have just this width and depth, the side surfaces just this depth and height. The end faces are preferably flat.

The Stirnfächen are usually the smallest outer surfaces of the vertical element.

The vertical element forms, for example, a shelf side wall, a shelf partition wall, a foot element or parts thereof.

The horizontal element has in particular a downwardly and upwardly facing side surface. The horizontal element has at least one upwardly or downwardly facing side surface at least one recess for receiving a connecting element. The side surface of the plate-shaped horizontal element is understood to mean a surface which has a significant influence on the plate shape of the horizontal element, as a rule the largest outer surface of a generally cuboid horizontal element, which preferably points downward or upward in the mounted state. The side surfaces are preferably flat.

The vertical element has a width, a height and a depth relative to its extent in the mounted state. The side surfaces of the horizontal element have just this depth and width, the end faces of the horizontal element just this height and depth.

The vertical element has on at least one end face at least one recess for receiving a connecting element, which is aligned with the recess on the side surface of the horizontal element, so that a connecting element arranged in a form-fitting manner in the recess on the side surface of the horizontal element and in the recess on the end face of the vertical element is.

The recesses in the horizontal element and / or in the vertical element are preferably designed as a blind hole, so that a connecting element in the assembled state can be arranged completely within the horizontal element and the vertical element and can not be seen.

The recess may be designed as a bore.

The recess on the end face of the vertical element is arranged asymmetrically with respect to the width of the end face, so that along the width next to the recess, a further recess fits on the end face, preferably on a short side of the end face. The space next to the recess can remain free.

But it can also be two adjacent, each asymmetrically with respect to the width of the end face arranged recesses provided. These are preferably mirror-symmetrically arranged with respect to a front surface perpendicular to the width dividing mirror line.

The horizontal element covers only part of the end face of the vertical element, which preferably extends over the depth of the end face. Preferably, the horizontal element covers one half of the end face, which extends in particular over the depth of the end face, so that the end face is divided perpendicular to the width of the end face of the horizontal element.

The recesses extend in particular within the overlapping area, preferably parallel to a side surface of the vertical element.

In an advantageous embodiment of the invention, two or more recesses are provided along a long side of the end face of the vertical element, which are arranged along a line parallel to the depth of the end face, and corresponding recesses on the side surface of the horizontal element.

In one conceivable embodiment, the depth of the vertical element, given, for example, by a long side of the end faces, is the same length as the depth of the horizontal element, given by one side of the side surfaces, so that a shelf can be built, the vertical and horizontal elements are the same depth and close the front and back flush with each other.

Alternatively, the depth of the end surfaces can be significantly shorter than the depth of the side surface of the horizontal element. In this case, a plurality of vertical elements on one side of a horizontal element may be needed to construct a shelf.

Preferably, the horizontal element is a shelf whose depth is greater than or equal to the depth of the vertical element. However, the horizontal element can also be a niche element whose depth is less than the depth of the vertical element. A niche element can serve in a rack structure to bridge the distance between two vertical elements, without creating an additional shelf. It can thus be formed with vertical elements of low height shelves with a greater height. This results in the height of the shelf from the sum of the heights of Vertical elements that are bridged by a niche element plus the height of the niche elements.

In a non-inventive embodiment, the node connection comprises as a connecting element, preferably releasably lockable, connector. A first part of the connector is arranged in the recess on the end face or in the recess on the side face. A second part of the connector is arranged in a recess aligned therewith. From the first and second part of the connector, a closure is formed, preferably by locking.

For example, an opening can be provided in the side surface of the vertical element into which a tool can be inserted for locking the connector.

A node connection with locked closure can be fixed and also hold independent of the weight of the horizontal and / or vertical element. A built with such node connections furniture can be hung, for example, on a wall. Without interlocking hold the node connections, as long as a piece of furniture built on the floor and is not raised.

The node connection according to the invention comprises a connecting element which comprises or consists of a dowel. The dowel can be stuck in a recess and in a matching, corresponding, recess. The dowel is preferably permanently mounted in a recess on an end face of the vertical element to be aligned upwards or downwards and / or in the recess on a side face of the horizontal element which is to be aligned upwards or downwards, for example glued or screwed in.

Preferably, the dowel is fixedly mounted in a recess on an upwardly facing end surface of the vertical element and / or in a recess on an upwardly facing side surface of the horizontal element. A node connection can then be constructed from bottom to top by first providing a horizontal element or vertical element and placing a vertical element or horizontal element thereon, with the upwardly facing dowel inserted into the corresponding aligned recess. In this the plug can be clamped or also glued. The dowel can also serve only to prevent lateral displacement, so that the node connection holds substantially by the weight of the vertical element and horizontal elements and can be easily solved again.

The dowel may be a metal or wooden dowel. The dowel preferably forms a positive connection with the recess perpendicular to the insertion direction.

In the embodiment according to the invention, the node connection has a connection element which comprises a dowel which contains a ferromagnetic material. For this purpose, the dowel is provided, for example, with a corresponding cover, for example a sleeve, or a core element. The ferromagnetic material is preferably fixedly attached to the dowel, for example clamped or glued.

The connecting element further comprises a permanent magnet, which is arranged in a recess, preferably fixedly mounted. The permanent magnet can for example be screwed or glued.

When building the node connection, the dowel is attracted to the permanent magnet and holds it in place. The assembly is facilitated and the node connection can be solved again. No tools are required for assembly and disassembly.

Analogously, the node connection may comprise a connection element comprising a dowel containing a permanent magnet, for example provided in the form of a corresponding cover or a core element. In addition, the connecting element comprises a ferromagnetic material, for example a sleeve, which is arranged in the aligned recess, preferably fixedly mounted. Also with this connection variant, an easily mountable and easily detachable node connection can be made.

The node connection can be designed so that the distance from the center of the recess on the vertical element to the edge of the end face is the same size as the distance from the center of the recesses on the horizontal element to the edge of the side surface.

The elements of the node connection can then alternatively be combined to form a non-inventive node connection, in which a horizontal element covers the entire end face of the vertical element flush. Such a node connection can be combined in a shelving system with node connections according to the invention and can be used, for example, at the edge of a shelf.

The node connection is advantageously designed so that the wall thickness of the vertical element is greater than or equal to the wall thickness of the horizontal element. The wall thickness of the vertical element may correspond to the width of the vertical element and the wall thickness of the horizontal element may correspond to the height of the horizontal element.

A vertical element then offers enough space on its end face to support two horizontal elements with sufficient stability.

Preferably, the wall thickness of the vertical element is greater than or equal to 30 mm. On this width either a recess of sufficient size can be mounted asymmetrically or two sufficiently large recesses can be arranged side by side.

The horizontal elements have on at least one side surface at least one recess for receiving a connecting element, which is arranged at the edge of the surface, that in an aligned arrangement of recess of a vertical element and recess of a horizontal element, the horizontal element only a part of the end face of the vertical element, the preferably extends over the depth of the end face, covering.

The vertical elements have on at least one end face at least one recess for receiving a connecting element. The recess on the end face is arranged so that a further recess fits next to it, preferably on the width of the end face, so that in an aligned arrangement of recess of a vertical element and recess of a horizontal element, the horizontal element only a part of the end face of the vertical element, preferably via the depth of the face extends, covering.

For the assembly of the permanent magnets, it has proven to be particularly advantageous if the permanent magnet is placed on the head of a previously screwed screw. Flat head screws are particularly advantageous for this purpose. The permanent magnet can also be placed on the screw head before screwing in the screws, for example by gluing. In contrast to permanent magnets, which are screwed on a screw hole, there is less danger of excessive load and thus a break when mounted permanent magnet.

Alternatively, however, it is also possible that the permanent magnet is loosely inserted between the head of a screwed-steel screw and the front side of a dowel provided with a steel cap. It has surprisingly been found that a firm connection of the permanent magnet with a connecting element is not absolutely necessary. Rather, the permanent magnet between a ferromagnetic material, which is assigned to the horizontal element and a ferromagnetic material, which is associated with the vertical element, are loosely inserted. With correct polarity and magnetic force of the permanent magnet ensures sufficient bonding force between the horizontal element and the vertical element. Evidently, it is advantageous that the magnetic forces are determined such that upon release of the compound, the permanent magnet always adheres to the same component, so for example always on the head of the screwed screw.

The object is also achieved by a shelving system for the construction of node connections, as described above, consisting of plate-shaped horizontal elements, preferably plate-shaped, vertical elements and connecting elements.

In this case, the horizontal elements on at least one side surface on at least one recess for receiving a connecting element. The vertical elements have on at least one end face at least one recess for receiving a connecting element.

The recess on the end face is arranged asymmetrically with respect to the width of the vertical element, so that a further recess fits next to it, preferably on a short side of the end face, and the recess on the side face is arranged so close to the edge of the face that in an aligned arrangement of Recess of a vertical element and recess of a horizontal element, the horizontal element only a part of the end face of the vertical element, which preferably extends over the depth of the end face covers. Preferably, one half of the end face is covered.

The shelving system preferably has horizontal elements with recesses on both side surfaces, that is to say on the side surface which is preferably downwards and on the side face which preferably faces upwards. With these horizontal elements can be node connections create the vertical elements connect to the top and bottom. The shelving system may comprise horizontal elements with recesses on only one side surface, for example the preferably downwardly facing side surface. These horizontal elements can serve as the top cover of a shelf. The shelving system may include horizontal elements with recesses only on the upwardly facing side surface. These horizontal elements can serve as a base plate of a shelf.

The shelf system can vertical elements with recesses only on one end face, for example, the preferably upwardly facing end face, include. These vertical elements can serve as foot elements of a shelf.

The shelving system comprises simple elements, namely horizontal elements, vertical elements and connecting elements, which can be combined depending on the length to different shelf structures, each wall is only simple, so constructed in a simple material thickness. Double floors or sides are not needed.

Each element is only as long as it is necessary for a compartment size of a shelf. Boards with lengths exceeding a shelf size are not necessary. Each node connection can be of the same type, so that an aesthetically pleasing overall picture arises for a built-up shelf.

Preferably, the shelving system comprises plate-shaped horizontal elements and vertical elements with a simple basic shape, namely cuboidal elements, in which the side and end faces have a rectangular or square shape, side and end faces of an element are each parallel to each other, wherein side and end faces of an element one Include right angle.

Both from above, as well as from the sides and from the front, only single joints can be visible on the built-up shelf.

A built shelf can be easily extended to other subjects, with the extension has similar node connections and the connection to the existing shelf with similar node connections can be produced.

Once a shelf has been built, it can be dismantled again and the elements can be joined together to form another shelf structure.

The shelving system can be offered as a modular system, from which the parts are selected, which are desired for a particular shelf structure.

The shelving system may comprise vertical elements with two recesses lying side by side on an end face for the connection of horizontal elements on both sides. The recesses are preferably arranged next to one another on a short side of the end face. The vertical element preferably has further pairs of recesses along a long side of the end face. In each case, two horizontal elements can be connected to such vertical elements per end surface, covering, for example, each half of the end face.

Two adjacent horizontal elements can then be connected to one another indirectly via a connection to the same vertical element.

Such vertical elements can be used as partitions of a shelf. They may also be used as sidewalls with one of the recesses left unused and visible when establishing a node connection as described above. A shelf can then be easily extended in the direction of the unused page.

Alternatively, a horizontal element can cover both recesses and a node connection not according to the invention can be produced.

The shelving system may comprise vertical elements which each have adjacent recesses on the downwardly and upwardly facing end faces, so that a vertical element can be built on two adjacent horizontal elements and can be assigned with two horizontal elements. Such vertical elements can be connected on both sides both downwards and upwards.

The recesses on the vertical elements and the horizontal elements can be arranged so that adjacent horizontal elements abut each other in two-sided connection. The node connection thus constructed is particularly stable, because the horizontal elements support each other.

For the one-sided connection of horizontal elements, the shelving system can have vertical elements with asymmetrically arranged recesses, preferably with respect to the short side of the end face. Such vertical elements can be used as side walls of a shelf.

The shelving system may comprise vertical elements, which comprise side-by-side recesses for double-sided connection of horizontal elements only on the upwardly or downwardly facing end face. On the other end face asymmetrically arranged recesses may be provided for unilateral connection of horizontal elements. These vertical elements can form together with horizontal elements corners in a shelf structure.

The shelving system may include door elements that are attachable to vertical elements. For this purpose, vertical elements may be provided with recesses on which hinge fittings can be attached. Cabinets can thus also be erected with such a shelving system.

Alternatively, door elements may be provided which can be fastened to the horizontal elements. For this purpose, the door elements may be equipped with spigot strips which are storable via spring-loaded pins in recesses of horizontal elements. Horizontal elements which are provided for the attachment of door elements, moreover, may further comprise recesses in which magnets for magnetic and / or magnetic pusher closures can be attached.

The shelving system may include drawer elements that can be inserted into compartments to be formed from horizontal elements and vertical elements. On horizontal elements and / or vertical elements recesses may be provided, to which rails and / or stoppers can be attached. With such a shelving system can thus be built chests.

The shelf system may moreover comprise storage boxes which are adapted in their dimensions to the mass of the horizontal and vertical elements such that the boxes can be inserted into compartments to be formed from horizontal elements and vertical elements.

The shelving system may further comprise rear wall panels, baffles, for example for covering foot elements, niche elements and / or reinforcing elements which counteract shear of the shelf structure.

According to the invention, the shelving system comprises connecting elements which bring about a magnetic closure. The connecting elements comprise a ferromagnetic material and a permanent magnet.

For example, wooden dowels may be provided which are fixedly mounted or mounted at one end in a recess of a vertical or horizontal element and at the other end comprise a ferromagnetic sleeve, for example a steel cap. In the recess corresponding to the node connection, a permanent magnet may be mounted.

The dowels can be stuck as conventional dowels in a recess and / or glued and are pulled by the permanent magnet in the corresponding recess and held there.

The vertical and horizontal elements may, for example, be equipped with permanent magnets on the recesses on the downwardly facing end or side surfaces.

When building a shelf, it is then already visible on the pre-assembled connection elements which surfaces should face upwards and which surface should face downwards.

A shelf structure, which has only node connections with only magnetic closure, can be mounted and removed without tools.

For a hanging mounting the shelf structure is not suitable. To allow a hanging shelf assembly, the shelving system may include lockable connectors.

The shelf system may include different fasteners, so that a shelf structure can be equipped with different fasteners. For example, can be provided for the body of a shelf structure pure connectors and for the top, bottom and / or the edge plates magnetic and / or lockable closures.

A shelving system includes, for example, horizontal elements 2 with a wall thickness 22 of 30 mm, a depth of 380 mm and with lengths of 360 mm, 690 mm, 1020 mm and 1350 mm. Shelves of greater height can be created, for example, with niche elements. For this purpose, the shelving system horizontal elements with a wall thickness 22 of 30 mm, a depth of 30 mm and with lengths of 360 mm, 690 mm, 1020 mm and 1350 mm.

8th shows a connection between a door element 24 and horizontal elements 2 in a sectional view from the side. The door element 24 has an upwardly facing recess 32 in which one with a spring 33 stored upper pin 34 plugged. The pin 34 is at his out of the recess 32 outstanding end rounded so that it easily into a recess 35 It is feasible to work on a horizontal element 2 is provided.

The door element 24 also has a downwardly facing recess 36 in which also a pin 37 with rounded end. The pin 37 is in a recess 38 on a horizontal element 2 feasible.

The door element 24 is in the mounted state by a through the pins 34 . 37 extending axis 39 rotatable.

The 9 shows yet another variant of a node connection with an alternative attachment of the permanent magnets 17 , In contrast to the embodiment according to 6 the permanent magnets have no screw opening through which the screws 18 are screwed into the horizontal elements. The permanent magnets, however, are directly on the head of a Flat headed screw 18 placed. In this way, the permanent magnets are not weakened by a bore and there is also no risk of breakage by a too tight tightened screw. The ferromagnetic covers 16 in the form of nickel-plated steel caps are as in the embodiment according to 6 on the dowels 14 placed.

The permanent magnets 17 are not fixed to the head of the nickel-plated steel screws in the present embodiment 18 connected, but adhere only by magnetic force on this. The permanent magnets 17 are thus loose between the screwed steel screws 18 and the steel caps 16 on the dowels 14 inserted, which obviously also facilitates the assembly considerably. However, the magnetic force of the permanent magnets is chosen so that when releasing the connection, the permanent magnets always remain on the screw heads within the bore, thus preventing individual permanent magnets from being lost when handling the vertical elements.
