Partition system

Description

The invention relates to a partition wall system according to the preamble of claim 1.

Known partition wall systems use a frame or post-and-beam wooden construction that is clamped between the floor and ceiling and covered with suspended or attached shells or panels. DE 24 08 420 B2 describes an example, according to which posts set up at equidistant intervals with adjustable spring force are braced by an adjusting screw compression spring system between crossbars fixed to the floor and ceiling. The posts are clad on both sides with wall panels that are hung on the posts using tongue-and-groove connections that run roughly parallel to the crossbars and can have different surface designs as required.

In other partition wall systems, the wall panels, which are usually floor-to-ceiling, are provided with peripheral profile strips that interact with clamps attached to the posts (see DE 22 24 394 A1).

DE 16 09 384 A1 describes a partition wall that is assembled from individual prefabricated partition wall elements. Each of these has a sheet metal casing into which a self-supporting wooden frame made of softwood is inserted, the spaces between which are filled with sound and heat insulating glass fibre mats or grey cardboard honeycombs. To stabilize the partition wall elements, the size of which is the room height

G1032

Horizontal wooden strips are provided to ensure that the wall can be moved freely. The partition wall is constructed on a wooden strip on the floor, with the wooden frames of the wall elements being braced against a wooden strip on the ceiling using tensioning screws. To connect the wall elements to one another, the outer edges of the wooden frame are provided with circumferential longitudinal grooves into which box-shaped sheet metal profile strips are inserted for suspension.

The problem with the partition walls mentioned is that they have to be individually adapted to the given room dimensions. Posts, wall panels and wooden frames have to be cut to size or prefabricated after detailed prior planning, which has a negative impact on the overall cost of the partition wall. Special components are also required for the installation of doors and/or windows in order to be able to design the wall surface without gaps. Short-term changes or additions, as well as later conversions or redesigns, are not possible or only possible with considerable effort. Recycling individual components is usually not possible because they are damaged when the partition wall is dismantled. In addition, almost every new installation situation requires different dimensions.

It is an important aim of the invention to overcome these and other disadvantages of the prior art and to create a partition wall system that can be manufactured inexpensively using simple means and is easy to handle. It should be easy to adapt to given room dimensions and architectural specifications, without the need for individually prefabricated wall elements and be able to be assembled in a modular manner without any special technical knowledge. Furthermore, the aim is to ensure economical production and storage of the required components. The construction, conversion and dismantling of a wall should be quick and easy, and the appearance of at least individual wall sections should be able to be changed quickly without major effort.

Main features of the invention are specified in claims 1 and 8. Embodiments are the subject of claims 2 to 7 and 9 to 28.

A partition wall system for the construction of non-load-bearing interior walls, room dividers or the like, according to claim 1, comprises wall elements in the form of building blocks, which can be connected to one another without posts to form a wall surface by means of connectors and are connected by clamping elements between room boundary surfaces

G1032

can be clamped, wherein the lengths of the modules and the distances between the connectors are equal to a basic dimension or a multiple thereof, wherein the connectors each connect at least two adjacent modules to one another and wherein at least one module itself forms a clamping element.

With the system according to the invention, room dividers as well as complete walls and entire rooms - e.g. room within a room - can be designed in a variable or uniform manner. The walls created can be quickly and easily erected, dismantled or rebuilt at any time. All components can be completely reused. The construction dust that occurs during conventional conversions is avoided with this system. It therefore offers families, companies and all institutions that need changing conditions the opportunity to meet current space requirements in a short time, in a way that saves raw materials and promotes health. A move can also be carried out at any time with the interior design system.

According to claim 2, the building blocks can be multi-edged and have different edge lengths in one direction, each of which corresponds to the basic dimension or a multiple of it. Preferably, in accordance with claim 3, they are flat cuboids or cubes, which according to claim 4 are made of solid material, preferably solid wood, but in the alternative of claim 5 can also be hollow. In any case, you have building elements that are easy to assemble and can be joined cleanly and precisely.

According to claim 6, the building blocks can be provided with at least one depression and/or with at least one projection on one surface. According to claim 7, building blocks that are flush and/or adjoin one another can form a closed wall surface, thereby achieving an attractive appearance with high strength.

In the design according to independent claim 8, the modules for receiving the connectors have recesses in the front and side surfaces, the distance between which is an integer multiple of the basic dimension and the number of which is determined by the longest edge length of a surface, wherein the distance of each recess to an edge of the module is half the basic dimension.

G1032

According to claim 9, the connectors are round rods that can be fitted into the recesses and have a length that is, for example, an integer multiple of the basic dimension, but can also be shorter or longer than this. According to claim 10, they can be made of wood, preferably solid wood with a smooth or roughened surface, for example in the design according to claim 11, all-round grooves that are particularly parallel to the axis and a few tenths of a millimeter deep, which supports the plug-in fit. According to claim 12, other connectors or screw-in parts have an external thread that screws into the recesses or holes with an internal thread. According to claim 13, the recesses can be designed as blind holes that reach to the inner center of the building block. These means always achieve a firm, but also detachable connection. According to claim 14, several building blocks can be penetrated vertically or horizontally by connectors, which gives the wall structure particularly high rigidity.

The design of claim 15 is important, according to which a rotatably mounted threaded bolt with a free end is arranged in the clamping block, which is laterally stabilized and can be pressed against a space boundary surface in the longitudinal direction of the block. According to claim 16, the free end has an exchangeable thrust piece that can be moved in the axial direction by the threaded bolt. According to claim 17, the clamping block has a head that can be inserted vertically or horizontally into the wall surface, the dimensions (edge lengths) of which correspond to the basic dimension or a multiple of it. Claim 18 provides radially directed engagement holes on the circumference of the threaded bolt for inserting a tool, rod or the like, which are accessible according to claim 19 through a lateral clamping block opening, which can preferably be closed with a cover according to claim 20.

Claim 21 provides that the clamping elements can be installed transversely to a spatial boundary surface, namely according to claim 22 in a given number parallel to one another, in particular at regular intervals.

According to claim 23, a gap between a room boundary surface and the building blocks closest to it can be bridged by a closure or by at least two push pieces and/or covered by at least one plate. The partition wall thus adjoins the room boundary without a gap, e.g. to a ceiling.

G1032

According to claim 24, further components can be fixed in the recesses of the building blocks, for example end panels, facing profiles, cover strips, decorative elements and the like. According to claim 25, at least one column can be braced vertically, diagonally or horizontally between room boundary surfaces.

According to claim 26, at least one wall opening can be formed in the wall surface, which can be a walk-through passage, a window or the like, thereby gaining great freedom in interior design. A wide range of other possibilities open up according to claim 27, in that two or more wall surfaces can be constructed equidistant from one another, and/or in that the system can be expanded in a third spatial direction according to claim 28.

Further features, details and advantages of the invention emerge from the wording of the claims and from the following description of embodiments with reference to the drawings. They show:

G1032

Fig. 1 shows an oblique view of a partition wall system 10. It consists of building blocks 20 and decorative elements. They are connected to one another via connectors 40 to form a wall surface 12, which can be stabilized by bracing against room boundary surfaces 14. For this purpose, clamping blocks or clamping elements 60 of variable length or height are used. After installing a clamping element 60 that is initially made to an undersize, a thrust piece 82 can be extended from it, which bridges a gap between the room boundary surface 14 and the wall surface 12 at the end (see Fig. 6b). If clamping elements 60 are installed on opposite sides of the wall surface 12, the wall surface is braced by bridging gaps on both sides between two support surfaces 14.

In the example of Fig. 1, the building blocks 20 are cuboid or cube-shaped. All building blocks 20 have a square cross-section with a uniform basic dimension 24. The building block lengths are a whole number or fractional multiple of this basic dimension 24. A cube-shaped building block 20 naturally has one and the same three-dimensional basic dimension 24 and has, for example, three recesses 32 that meet in the center. It can also be penetrated by intersecting holes 34. In cuboid-shaped building blocks 20, recesses 32 are made in the middle on at least two opposite sides at a distance of one basic dimension 24 each; these recesses can be through-holes. Within the scope of the invention, it is provided that at least one visible building block surface is free of recesses 32 and holes 34. The building blocks 20 are preferably made of solid wood, but can also be made of plastic, clay or loam building materials, or of or with metal and/or composite materials. To protect the climate, they can be impregnated with linseed oil, coated with varnish or the like.

The building blocks 20 are connected to one another by connectors 40, which can be made of the aforementioned materials, are rod-shaped and generally do not exceed the length of a basic dimension 24, except when they pass through holes of several adjacent building blocks. In order to enable a firm but detachable fit, the rod diameter d is as large as that of the recesses 32 or through holes 34, or at most slightly smaller. The rod surface 42 is generally smooth, but can also be provided with grooves or ridges 48, e.g. of a tenth of a millimeter depth, for special holding tasks, or can also have an external thread 46 if a screw connection with an internal thread 36 is required in

G1032

a recess 32 or bore 34. Decorative pins, cover caps 38 or the like can be used in the same way.

Fig. 2a to 4b show the structure and function of a clamping block 60. In the hollow interior, which is closed by a removable cover 95, it has a threaded bolt 72 which is rotatably mounted in a threaded bushing 73. The thrust piece 82 is loosely placed on the upper free end 76 of the latter. The threaded bolt 72 is smooth-cylindrical at its lower end, i.e. it has no thread. A ring body or block 86 which is slipped over there and firmly connected to the threaded bolt 72 is guided on side walls 62, 63, 65 of a shaft 61. The block 86, like the threaded spindle 72, is preferably made of wood or metal and has radial engagement holes 90 on the circumference 88 which are arranged one above the other at height intervals and are offset at an angle to one another for a rotary handle, for example a rod-shaped tool 92 (see Fig. 5). If there are three holes 90 as shown, the angular offset is 60° each. Metal sleeves 75 (Fig. 4a, 4b) can form linings which protect against mechanical damage and at the same time reinforce the fastening of the block 86 to the spindle 72.

To operate the clamping element 60, first remove the cover 98 which has been pushed or folded into the lower part of the front side wall 65, for example. The rotary handle 92 is then inserted into one of the engagement holes 89 and moved to the right or left. With repeated pivoting movements, whereby the handle 92 is inserted into a new engagement hole 90 which appears each time, the spindle 72 is screwed upwards in the threaded chuck 73 or downwards if the direction of rotation is reversed. The lifting or lowering movement of the threaded bolt 72 continues in the loosely resting thrust piece 82 which, depending on the screwing direction, moves a little out of the upper guide area of the clamping module 60 or deeper in. As soon as the thrust piece 82 strikes a boundary surface 14, the clamping effect begins.

In Fig. 6a to 8b and in Fig. 11, various partition wall systems 10 can be seen. They each consist of a wall 12 to which decorative, blind and/or wall opening elements are attached. How a closure with a room boundary surface is achieved in an elegant and perfectly formed manner can be seen above all in Fig. 6a, 6b and in Fig. 7a, 7b. The wall 12 is first clamped by means of clamping elements 60 against at least one room boundary surface (not marked here). In this case, either the free end 76 of the threaded bolt 72 presses directly on a

G1032

adjacent boundary surface or the thrust piece 82 does this with its head 95 of square, rectangular or even round shape.

End plates 120 can be attached to the wall 12 by means of connectors 40 in such a way that they essentially cover gaps between it and the boundary surface 14. For this purpose, groups of recesses 32 or holes 34 are provided in rows one above the other in the component 120, which have vertical spacings of, for example, a quarter of the basic dimension and are arranged in the horizontal or transverse direction at a distance of a whole basic dimension 24 (Fig. 7a, 7b). The end plates 120 have a minimum height of two rows of building blocks, but in the examples shown they are of such a height that they also at least essentially cover the gap above them. They can be designed differently, especially on their lower edge, e.g. curved or in the style of classical architectural styles. For example, one can easily recreate the Doric, Ionic, Corinthian, Gothic or Romanesque style. The panels 120 can also contain futuristic or Art Nouveau elements.

Front profiles 130 of a lower height can be fitted onto the end plate 120. These can be provided in their lower area with ornaments and decorations of the styles mentioned, for example, and also have several recesses 32 or holes 34 lying vertically one above the other, again at basic dimension distances from one another and at smaller distances one above the other in order to achieve optimal height compensation. In the same way, a cover strip 140 can be fitted onto the front profile 130, which for example projects forwards and rests directly against the room boundary surface at the top. If exposed recesses 32 or through holes 34 on one of the components 20, 120, 130 are a nuisance, they can be covered with blind closures such as plug-in caps 38 (Fig. 1) or with plug-in elements 142.

Wall openings 110, e.g. window or door openings, are shown in Fig. 8a, 8b and 11. These are constructed from large-area wall elements, namely from special building blocks 20 of very different shapes provided with recesses 32 or holes 34. For example, for a passage in the Gothic style, five special building blocks 20 are advantageous, namely two posts 152, two door arch elements 154, two column bodies 156, two decorative half arches 158 and a keystone 160.

&iacgr;.&Tgr;

G 1032 ··....· \.*, _## &iacgr;·; * &iacgr; Page 9

the posts 152 and arches 154 can even take on a supporting function, while the elements 156, 158, 160 have a decorative character.

If a wall 12 cannot be braced against a boundary surface, e.g. because it ends in the middle of the room, patterns of square edges and edge surfaces are created at this point. In order to create a harmonious overall impression, panel elements are provided, such as head end elements 162 and side end elements 164 in the embodiment of Fig. 9, which are attached to a wall 12 with the thickness of two building blocks 20. These components are also preferably designed so that their dimensions are a whole or partial multiple of the basic dimension 24.

To construct a partition wall system 10, building blocks 20 are conveniently placed in a row one behind the other on a pre-drawn floor plan. The second and each subsequent row are placed flush with the surface and offset. At all locations intended for a wall opening 110, building blocks 20 are layered on top of one another without connectors 40 so that they can be removed again from the finished wall 12. At the beginning and end of the first or second row and then at a distance of e.g. 1 m each and below or above a wall opening 110, tensioning elements 60 are built into the end of the wall 12. A wall 12 braced with only one lateral room boundary surface is supported at the end during construction by building blocks 20 loosely stacked perpendicular to it, which are removed again after the wall 12 has been completed.

Every 1 m of construction progress in height, the structure is compacted, e.g. using a rubber hammer. After alignment with a spirit level, vertically and horizontally, the wall 12 is fixed by operating opposite clamping elements 60 between the lateral room boundary surfaces. Just below an upper stop surface, clamping elements 60 are built into the wall 12 at approximately meter intervals and additionally on both sides above a wall opening 110. In order to finally align and stabilize the latter, the clamping elements 60 attached to the sides are loosened again slightly, the wall 12 is compacted again by operating the clamping elements 60 directed towards the upper room boundary surface and finally the lateral expansion elements 60 are tightened again.

Attachable decorative, cover and/or wall opening elements complete the partition wall system 10 in the character of the selected architectural style. Examples can be seen in Fig. 6a and 6b, where a cover plate 120 is provided with a front profile 130, which leaves a lower decorative area 122 free and which in turn is overlapped by a cover strip 140. The arrangement according to Fig. 7a and 7b is similar, where one can see the optimization of the height compensation through closer spacing of the recesses 32 or holes 34, which are specifically a quarter of a basic dimension 24.

The designs of Fig. 8a, 8b and 8c are also comparable. Here, the wall surface 12 leaves an opening 110 free, in which posts 152 support door arch elements 154, which are attached laterally to the building blocks 20 of the middle rows 16 by connectors 40 (not shown). The ceiling is finished off by a facing profile 130, possibly with decorative elements screwed on or attached in some other way (Fig. 8a) or with a combination of panels 120, profiles 130 and cover strips 140 (Fig. 8b, 8c). The opening 110 can be covered by inner panels 150 and outer panels 160, but decorative millings can also be provided on arch elements (Fig. 10).

Fig. 9 shows a double wall, the building blocks of which are provided with through holes 34 and are covered by end closures 162, 164 attached to them with connectors 40. It can be seen that a head closure 162 lies snugly against a contact surface 166 and side closures 164 can be attached with an overlap 168.

The invention is not limited to one of the previously described embodiments, but can be modified in many different ways. The partition wall system 10 can also contain special building blocks 20 with which free-standing columns 170 can be firmly erected in the room. A rod-shaped support, for example, can serve as a tensioning element with a stylish appearance.

Building blocks 20 installed in the wall 12 can also have edge lengths that are, for example, half or quarter multiples of the basic dimension 24. Furthermore, in the case of long building blocks 20, the through hole 34 in the longitudinal direction can be replaced by a hole at each end with the length of a basic dimension 24. Likewise, the connectors 40 can have a length that is a multiple of a basic dimension 24.

G 1032 · ^: **·. ^: * \.i ;*· &iacgr; : pages

dimension 24, and not only a whole number, but also a fractional multiple. The thrust piece 82 can be T-shaped or can replicate the shape of a building block 20 on a side protruding from the clamping element 60. Furthermore, the number of engagement holes 90 in the ring block 86 can vary, depending on its thickness and, if necessary, on whether a clamping element 60 is to be stiff or easy to move.

It can be seen that the invention, in addition to its functional advantages, allows the realization of a wide variety of interior design designs by using the new wall system to create a quickly changeable, individual room ambience as required. Easily adaptable decorative elements such as columns, half columns, cornices, door and window arches, skirting boards and ceiling moldings, etc. in a wide variety of styles can contribute to this. Aesthetic changes can thus be implemented quickly and inexpensively.

All features and advantages arising from the claims, the description and the drawings, including structural details, spatial arrangements and method steps, can be essential to the invention both individually and in a wide variety of combinations.
