Description

Technical field

BACKGROUND OF THE INVENTION The invention relates to a connection system, in particular for the installation of spatial cells and prefabricated furniture, as well as for complex interior design and exhibition space, consisting of horizontally divided connecting elements with one to eight crossbeam connections, supports, connecting screws arranged in the longitudinal axis elements, crossbars, end elements and height adjustable foot elements. The decomposable elements of this joining system may be made of wood and the joining system may also serve for the complex rendering of interior designs, for example for the internal division of trade and exhibition spaces.

BACKGROUND OF THE INVENTION

Removable structural elements for the establishment of spatial cells and assembled furniture are usually made of metal, but this is associated with high production costs. Such structural elements are often very heavy and have no decorative effect or have only a minor decorative effect. Another disadvantage is that their construction details are often undesirable.

DE 39 33 845 A1 discloses a connecting node of a framed structure which serves to detachably connect a support provided with a recess on the front side by means of a support head with at least one purlin. The support head is provided with a shape element which at least partially corresponds to the shape of the recess in the support. The adjoining flange element carries one or more coupling devices which extend in a direction opposite to said element and which can be connected to a coupling tongue extending from the front side of the purlin.

This solution is associated with a costly construction and is also characterized by high assembly and disassembly costs.

DE G 92 11 330.3 already describes a multi-purpose universal wooden structural element intended for the installation of spatial cells and assembled furniture. This wooden component is made up of a connecting node with up to eight crossbar connections and is equipped with supports, connecting screws, cover caps and heel elements.

During installation, the crossbars or other horizontal connecting elements are simply suspended by means of one-sided dowels in the connecting node.

A significant drawback of this solution lies in the danger of the crossbar being cut off at the point of suspension. The connection is angularly unstable due to the one-sided suspension and also the overall stability is not satisfactory despite high material costs.

EP-A-0126657 discloses a connecting node, characterized in particular by the construction of metal mounting parts.

The connecting element has the shape of a tube, has a horizontal division, and slots are milled in the walls of the tube which extend from the division plane.

Crossbars are hinged into these slots, which are supported by dovetails on the inner wall of the fastener.

A clamping screw is used for clamping the connecting node, which axially extends through the two tubes of the connecting element and cooperates with a special clamping device.

Starting from this prior art, it is an object of the invention to eliminate the above-mentioned drawbacks and to increase the functionality and thus to extend the field of application of such connection or assembly systems. In addition, a connection system is to be provided in which the low strength of the wood is compensated even with the construction of the decomposable timber components and the minimum dimensioning of the timber components.

SUMMARY OF THE INVENTION

This problem is solved and the shortcomings of known fastening systems of this kind are largely eliminated by the fastening system, in particular for the installation of spatial cells and prefabricated furniture, as well as for complex interior design and exhibition space consisting of fasteners with one to eight crossbar, support , fasteners, crossbars, end elements and height adjustable heel elements according to the invention, characterized in that each fastener is horizontally divided and is provided on opposite inner sides with one to eight recesses with bores and longitudinal grooves for receiving and adjusting of the crossbars, wherein in the halves of the connecting element there are centrally formed through bores for sliding on the connecting screws, which are engaged with threaded sleeves which are recessed in the ends of the supports, functional supports, terminating and height-adjustable heel members and retain the crossbars with locking elements in the connecting element.

A stable connection of the thus formed skeletal structure is achieved in the joining system by pressing the supports on the crossbars anchored in the joining element, this pressing being achieved by means of a connecting screw.

Preferably, the crossbars are provided with grooves at their upper and lower edges for receiving the planar elements by means of interposed tongues. In this way, the necessary angular strength of the entire frame structure is achieved, both in the case of one-sided brackets and in the case of double-sided brackets, which are suspended between two functional supports.

The lengths of the crossbars and supports are preferably aligned with each other such that the lengths of the longer crossbars and supports are always a multiple of the lengths of the shorter crossbars and supports. In this way it is possible to extend the connection system by functional and aesthetically pleasing surface elements.

An important feature of the invention is that the connecting element is divided into two parts in the vertical direction.

To this end, the individual crossbars are tapered at their ends and are fastened in the respective halves of the connecting element by means of dowel-like locking elements which engage the corresponding bores in these halves.

The invention has created a design principle which, when made of wood, offers an extension of the field of application with adequate strength values. Assembly and disassembly is extremely simple and quick, while the durability of timber construction corresponds to the durability of the metal element construction.

The connection system according to the invention can be expanded in the horizontal direction indefinitely and in the vertical direction it can extend to the limit of its static load. Up to eight cross members can be connected in one plane to a single connecting element, allowing the construction of mounting elements up to octagonal constructions.

From the standard parts of the connection system according to the invention, in addition to the wall constructions for space design, reception desks, tables, pedestals, cabinets, racks, showcases, seating benches and the like can also be assembled.

The invention also relates to a connection system, in particular for the installation of spatial cells and assembled furniture, which consists of connecting elements with one to eight connections for crossbars, supports, connecting screws, crossbars, terminating elements and height adjustable foot members. At least a portion of the supports are designed as functional supports such that a transverse or longitudinally extending slit is formed between the threaded sleeves disposed at the front ends of the functional support and is operatively spaced perpendicularly to the longitudinal axis with the raster spacing along the longitudinal slot. the coupling elements are connected to one another in the longitudinal direction and the separated parts of the functional support are separated from each other, the width of the slit being given by the thickness of the one-sided brackets or double-sided brackets. This equipment further increases the functionality of the coupling system.

The invention also relates to a connection system, in particular for the installation of spatial cells and prefabricated furniture, which consists of connecting elements with one to eight connections for crossbars, supports, connecting screws, crossbars, terminating elements and height adjustable heel elements according to the invention. characterized in that the functional support is divided lengthwise and consists of two halves which are separated by a longitudinal slot and connected to each other by means of coupling elements, the front ends of the functional support being provided with threaded sleeves for mounting and the width of the longitudinal slot being given by one side thickness brackets or double-sided brackets which are inserted into this longitudinal slot and locked by coupling elements.

Thus, in the region of the longitudinal slot or longitudinal division of the functional support, binding elements, for example in the form of pins, are connected perpendicularly to the longitudinal axis of the functional support, which connect the two halves of the functional support to each other.

Thus, the functional supports can be divided in the longitudinal direction into two halves of any cross-section, which are spaced apart from one another by pin-shaped coupling elements. The threaded bushings for mounting with the fasteners are again located in the region of the front ends of the functional support. In the longitudinal slot of the functional support, one or more brackets or other brackets can be retracted in height and are subsequently hinged and locked using the aforementioned coupling elements. It follows that the width of the longitudinal slot, or the distance between the two halves of the functional support, is derived from the thickness of the brackets or the brackets in the area by which they slide into said longitudinal slot.

The brackets can be hinged on one or both sides in the functional supports, then serve, for example, to store tiles, rods for hanging clothes and wardrobe-forming elements.

The notches which are formed in the end regions of the brackets serve to lock the individual brackets which are inserted into said longitudinal slot.

In particular, the one-sided bracket is provided on the mounting side with two notches, which, when the one-sided bracket is inserted into the longitudinal slot of the functional support, engage two adjacent coupling elements.

If angular adjustability is required, the one-sided bracket on the assembly side is provided with three notches, whereby the engagement of two adjacent coupling elements in each of the two notches allows different angular positions of the one-sided bracket.

In the case of the double-sided bracket, the double-sided bracket is in each of its end regions equipped with one notch into which the coupling element engages after insertion of the double-sided bracket end regions into the respective longitudinal slot of both functional supports.

In the free area of the double-sided bracket, i.e. outside the area of its insertion into the longitudinal slot in the functional support, additional sliders may be provided which are connected to the laid elements such as an inserted tile and a clothes rail. In addition, these riders can compensate for different console heights and can perform other functions.

The sliders are connected to the double-sided bracket, for example, by a groove which is formed in the underside of the sliders.

Instead of brackets, height-adjustable annular holders with receiving bores for bars and the like may be slidably mounted on the functional support as point fasteners, and these annular holders are provided with latches extending across the annular support for locking on the functional support, the longitudinal slot being the functional support. provided with a cut-out on its underside, into which the coupling element engages in the retracted position of this bolt.

In its retracted position, with its opposite side to the handle, the bolt extends into the opposite side of the annular holder. In the annular holder there are provided receiving openings into which, for example, clothes hangers can be inserted.

Further advantages and features of the invention will be apparent from the following description of an exemplary embodiment thereof.
