Description

Corner connectors, ESPECIALLY ECKVERBI SANTANDER FO R MODULAR CEE BELSYSTEME

The present invention relates to a corner connector, for example for modular öbelsysteme or the like, according to the preamble of the independent claim.

From the prior art several corner connectors and modular furniture systems are known. Especially with corner joints made of metal, there is a great variety. These are usually processed by machining process and fastened by screwing or clamping connections. Corner connector from thermoplastic materials such as plastics and the like which are produced by injection molding few known, although the production considerably cheaper fails especially in large quantities.

US4354768 I. Joseph Witek published 1982 and relates to a corner connector for connecting plastic pipes. This corner connector has a cubic Crundkörper with a molded-on leg. The corner connector is made of a relatively soft material so that more legs to operatively interconnect can be unscrewed from another pipe by self-tapping screws. A disadvantage is that the corner connectors due to the soft material offers little resistance. A further disadvantage is that by screwing the self-tapping screws, the risk that the corner connector is divided.

WO080621 61 by the company. Tecna Display Ltd. was published in 2008 and shows a cube-shaped corner connectors for the construction of three-dimensional structures, such as are used in stand. The corner connector consists of a cube which is operatively connected with a bayonet attached to the ends of rods star-shaped closure elements. To connect the closure elements are rotated by an angle inthe inserted into the Eckverb-, to be then locked by an opposite movement. The corner connector has undercuts, which are difficult to produce. For this reason, the corner connectors must be made in several parts, because otherwise it can not be removed from the mold.

US7014267 by the inventor Nir Nagar was published in 2006, shows a modular furniture system with rods, which can be plugged together by means of corner. The components of the furniture system can be made of plastic. A disadvantage is that the furniture system for the construction of complex structures requires different types of corner joints. This increases the manufacturing costs considerably and is therefore particularly disadvantageous in price-conscious embodiments, eg made of plastic. Information on products which are declared to fall within the aforementioned patent as are to be found www.2 kidsprod ucts.com/mod life.htm I.

EP0843103 from the company. Robert Bosch GmbH was published 1998 and is directed to a profile connection, which is suitable for protective and separators as well as racks and shelves. The apparatus comprises corner connectors, which serve for operatively connecting profile rails. The corner connectors have depending on the use of a different configuration. A disadvantage is that the corner connectors have a complicated and expensive design.

US6332657B Lukas Fischer Chamäleon Design was published 1999 and shows a corner joint for furniture. The corner connector includes an angled two-legged body, which can be added on one side by attaching to a tripod.

Coll 337,613 of the company. Porta Showers Ltd was published 1973 and relates to a corner connector made of plastic. The corner connector is provided in several embodiments with a different number of fastening legs, so that it can meet all the needs. One disadvantage is that a separate injection mold is required for each embodiment.

US3666298 the company. Beautiline Ltd. was published 1971 and relates to a corner joint for connecting tubular members. From the description, it appears that parts of the corner connectors are preferred to be made of plastic. A disadvantage is that different embodiments are necessary to cover all needs.

The following patent publications are of corner connectors for the construction of three-dimensional structures directed (Publication year in brackets): WO0238904A (2002), WO0066896A (2000), US55801 81 A (1996), US4082470A (1977) US1 400066A (1921). All corner connectors have a cube-like corner connectors, ssenflächen at the Au rods can be attached. The corner connectors all have a relatively complicated structure.

An object of the invention is to show a corner connector, which avoids the inherent in the prior art disadvantages.

This problem is solved by the features defined in the independent claims corner connectors.

In one embodiment, a corner joint according to the invention on a three-legged stable Crundkörper that can be flexibly extended depending on the application and modular by adapter. The Crundkörper consists essentially of a cube with six sides in which at an angle of 90 ° to each other in three adjacent first side surfaces at least one respective leg is formed above. By the integral design of the stability and load capacity is increased. Depending on the application, the principle can be extended to other embodiments, respectively angle. The fixed shaped legs are normally designed so that they are suitable for the detachable or non-detachable operative connection of rod-shaped connecting elements for the construction of three-dimensional structures. Depending on the embodiment, the legs can be operatively connected, for example by switching on and / or plugging with the rod-shaped connecting elements. Other types of mounting are possible.

The modular adapters work in principle as a removable legs that are used for flexible complement of the adapter, depending on where the corner connectors to be used. In contrast to the prior art, so that only a basic form of a corner connector is required for the synthesis of stable three-dimensional structures. This can be used very flexibly. The manufacturing and logistics costs are thus significantly reduced. Another advantage is that, for example, shelves or other three-dimensional structures, in contrast to the known prior art systems, flexible and can be expanded easily, without having to first be broken down with difficulty and rebuilt. In certain cases, the adapter may be integrated, at least on one side into the rod-shaped connecting elements, if necessary. However, this reduces flexibility and increases the cost of manufacture.

To operatively interconnect the removable legs (adapter) have three adjacent faces of the cube first operative connection means that are suitable for operatively connecting the removable legs formed on the second operative connection means. If necessary, other elements, such as feet or rollers can be fixed to the first operative connection means, etc.

In the first and the second operative connection agents are, especially in corner connectors made of plastic, with advantage to quick-release fasteners, such as Schnappverbindun- gen, which can be easily assembled and released. The snap connections may be made self-locking, such that they do not disengage under increased load. Alternatively or in addition, the first and second Wirkverbin- dung medium for example can be designed as a bayonet lock which can be locked by inserting and mutual rotation, for example to 45 ° or 90 °, relative to each other. A further possibility is to design the first and the second operative connection means as a screw connection.

An embodiment of the invention relates to a corner connector for a modular stem Möbelsy-. The corner connector includes a Crundkörper consisting of a cube with six side faces, on the first of three adjacent side surfaces of each leg is formed above, which is suitable for operatively connecting one rod-shaped connection element. The cube of the Crundkörpers has three second adjacent side surfaces operative connection means which are suitable for the application of detachable legs, such that the corner connector is flexible supplemented. Thus corner connectors can firmly molded and be built up to three modular supplemented legs so that all positions can be covered on a shelf, for example, with only three fixed-formed legs or three. The cube can be at least partially integrated in one of the formed legs, so that it is not visible from the outside. In the first and / or second connection means the active ingredients it may be quick fasteners that can be operatively connected easy. In a preferred embodiment, the first operative connection means about an opening and the second operative connection means to a guide pin. This is designed so that it can be anchored in the opening. The operative connection means can be designed as a snap and / or a bayonet lock. In one embodiment made of plastic comprises a leg has a substantially square and the other two legs of a H- or U-shaped in cross-section, such that the Crundkörper is simply removed from the mold in one direction. Other cross-sectional shapes are possible if necessary. The first operative connection means can serve to accommodate cover plates, which cover this optically. A erfindungsgemä- sser corner connector is suitable for the construction of a modular furniture system in which serves for operatively connecting rod-shaped connecting elements. The corner connector can also be part of a kit for a modular furniture system. Depending on the application, the removable legs can transmit dung be operatively secured to the rod-shaped Wirkverbin-.

Depending on the application, the first and the second operative connection means 6, 8 also have a different configuration. For example, it is possible to form them as a bayonet lock with a first male and a second male part, which fitted into one another and by mutual rotation, for example to 45 ° or 90 °, can be locked. Another possibility is to design the first and the second operative connection means 6, 8 as a screw cap with an opening with an internal thread and a correspondingly formed pin with an external thread which can be operatively connected to one another by screwing. Another possibility is to design the operative connection means that they can be inserted at least in the region of two side surfaces 5 of the die 3 from the side. The first operative connection means are designed in this case as the corresponding open side, slot-shaped opening. The second operative connection means by the legs 7 may have a dovetail-shaped configuration, which engages behind the slot-shaped opening of the first operative connection means in the suspended state.

In the present case the guide pin 9 and the opening 6 have a square cross-section and are rotated relative to the die 3 in the axial direction by 45 °. This ensures that the loads are better transmitted. In the side of the guide pins 9 arranged niches 1 1 0 1 the snap elements are arranged. These engage in mounting (shown schematically by a first line 1 2 as indicated) in the openings 6 a. The snap elements 1 0 may be detachably or non-detachably configured as needed.

The cross section (see FIG. 5) is square shaped and dimensioned so that the leg 4.1 snugly into a rod-shaped connecting element 1 7 (see FIG. 7) can be inserted and anchored. The other two legs 4.2, 4.3 are identically formed in the embodiment shown and have an H-shaped cross section (see FIG. 6), which can also be easily removed from the mold and in the same direction as the first leg 4.1. As can be seen in Figure 4, the openings open 6 (first operative connection means) from three sides into the interior of Crundkörpers 2. The second and third leg 4.2, 4.3 are on a side wall 5 is attached, and at a 90 ° angle to the first leg 4.1 arranged.

Figure 7 shows an example of a modular furniture system 1 6 which according to the invention corner connectors 1 and rod-shaped connecting elements 1 7 comprises. If necessary, a combination with other corner is resp. Operative connection means possible. For a general description of the structure and function of the corner connector 1, reference is made to the preceding figures. In the embodiment shown it is a part of a shelf. In the formed by the corner connector 1 and the rod-shaped connecting elements 1 7 squares shelves 1 may be used. 8 By erfindungsgemä- SEN corner connector 1, the shelf 1 6 is simple and extensible in all directions.

In the figures 8 to 10 a), b) two embodiments of adapters 7 are shown side by side. When the adapters 7 concerns removable legs, which are suitable for addition to a flexible Crundkörpers 2 a corner connector 1 according to Figures 1 to. 6 The adapters 7 have a shaft-shaped rear part 1 9 which is open at one end and opens at the other end in an end plate 20 on which second Wirkverbindungsmit- tel are arranged. 8 The two embodiments differ mainly by the configuration of the second operative connection means 8. Both the second operative connection means 8 comprise a (multi-part) guide pins 9 and a plurality of snap-in tongues 1 0, which are designed so that they in the axial direction (z-direction) are removed from the mold. The configuration and arrangement can be seen from the figures 8-1 0th In general, the adapters are manufactured by injection molding of plastic. 7
