Abstract

The partition has multiple wall elements (1) that are movably held by a guide unit (2). The wall elements have two parallel transparent pane elements (3) that are separated at a distance from one another. The wall elements have a profiled frame (4) for receiving the pane elements and for holding a soundproofing unit in order to seal the wall element against a floor and a ceiling in a soundproofing manner. The pane elements are formed from windowpanes i.e. single windowpanes, where the thicknesses of the windowpane are approximately 6, 8 or 10 millimeter.

Description

The present invention relates to a partition with a plurality of wall elements, which are movably received via a guide means. The lateral planar surfaces of the wall elements are formed by transparent disc elements to provide a transparent mobile partition of several wall elements.

Such wall elements for forming a mobile partition with transparent pane elements are used in rooms such as shops to form a mobile window front, in shops for variable separation of customer areas, in public buildings and in particular in banks, in which after closing an inner part of the customer area of an outer Part is separated. The transparent disc elements have fittings on which guide means are mounted to receive the wall elements, for example in a ceiling rail system and to lead in this. Often, the disc elements are arranged individually and form the body of the wall element itself. The fittings are then placed on the top and bottom of the disc element so that when several wall elements are juxtaposed to form the dividing wall, the disc elements are made of glass directly adjoin one another.

Such partitions with a plurality of glass elements, which are constructed of transparent disk elements, have the disadvantage that no sound insulation is possible, since the disk elements are on the one hand only simple and not double-walled and on the other hand have no seal in the edge region of the disk elements. Though wall elements are known for the formation of partitions which have sound insulation means, but such devices are not known for wall elements consisting of transparent disk elements. The problem already arises from the integration of a sound insulation device in the fittings, which border the disk element at least on the upper side and on the lower side.

Furthermore, partitions with a plurality of wall elements are known, wherein the wall elements have a frame structure, are used in the tailored panels, which consist of MDF panels, solid wood panels or plastic sheets. Such wall elements have sound insulation means to provide a soundproof mobile partition. Wall elements are also known with windows, which are introduced in the form of a cutout within the side plates in this. The window section inside the side plates does not interfere with the integration of the sound insulation device, which usually takes up a considerable amount of space and is based on a spindle system, are moved by the sealing elements both against the ground and against the ceiling of the room.

It is therefore the object of the present invention to provide a partition wall with a plurality of wall elements, which has an extended range of functions and achieves increased sound insulation.

This object is achieved on the basis of a partition of transparent wall elements according to claim 1 in conjunction with the characterizing features. Advantageous developments of the invention are specified in the dependent claims.

The partition according to the invention has a plurality of wall elements, which are movably received via a guide means, wherein the wall elements two arranged at a distance parallel to each other comprising transparent disc elements, and wherein the wall elements have a profile frame for receiving the disc elements and in which further a sound insulation device is received to seal the wall elements at least against a floor and against a ceiling sound-insulating.

The partition according to the invention combines the properties of a transparent partition with the advantages of sound insulation. Only through the inventive recording of the disc elements in a profile frame, the requirement is created to integrate a sound insulation device in the wall elements. The sound insulation is created on the one hand by the sound-insulating sealing of the wall elements against the floor and against the ceiling of the room, on the other hand, the plane-parallel arrangement of two transparent disc elements contributes to each other at a distance to the sound insulation. This is made possible only by the profile frame, which forms the wall element in combination of the transparent disc elements. Due to the given distance between the two transparent disk elements to each other, the effect of sound insulation is enhanced, with a greater distance between the disk elements leads to better sound insulation values.

Clipleists are provided according to the invention, through which the disc elements are received in the profile frame. The clipists are arranged on the profile frame on the outside, so that both disk elements are held by the clipists by means of an elastic pressure against the profile frame. The arrangement of the Clipleisten on the outside of the profile frame guaranteed depending on the profile thickness a maximum distance between the disc elements, which significantly increases the sound insulation.

According to an advantageous embodiment, the side surfaces of the wall element are predominantly formed by the disk elements, wherein the profile frame surrounds the disk elements only at the edge and encloses them. This creates a clear distinction between the wall element according to the invention and known wall elements which have non-transparent plates enclosed in a frame as side surfaces and which have a window cutout. Such conventional wall elements have side surfaces which are predominantly formed by the non-transparent side plates. In the present case, however, the wall element according to the invention has only one profile frame, which is made so narrow that it only appears on the edge side, and the disc elements are enclosed in the profile frame. The ratio between the side surface formed by the profile frame compared to the side surface formed by the disk element can be compared with a window sash of a building. In the case of a window sash, a window frame merely grips the window pane at the edge, without the window frame forming a significant part of the side surface of the window.

The disk elements of the wall element according to the invention can consist of all known transparent materials which can be used as such disk elements. Consequently, the disc elements may be made of a plastic material having transparent properties, as exemplified by acrylic glass (PMMA). However, the disk elements are preferably formed from glass panes, wherein at least one of the two disk elements may comprise a single glass pane or a double glass pane. By using double-glazed windows, in addition to improved sound insulation, heat insulation is also made possible, provided that the partition according to the invention has the function of thermal insulation. The profile frame can also have a thermal separation, in which this example, both an inside as Also has an outside aluminum profile, which are held together on plastic webs inside. This creates a barrier against a heat flow from a warm to a cold side, which are separated by the partition wall. It may be sufficient to carry out at least one of the two disk elements as a double glass pane, wherein the second glass pane may be a single glass pane.

It is also possible to form the glass sheets as single glass panes and to combine either with the same or with a different thickness. For example, it is advantageous to combine glass pane thicknesses of 6 mm and 6 mm, whereby a combination of 8 mm and 10 mm is also possible, which allows improved sound insulation. The combination of different glass pane thicknesses leads to lower resonance effects, which in turn can further enhance the sound insulation.

The greater the distance between the disc elements to each other, the greater the effect of the sound insulation. By contrast, the wall element should not exceed a given width dimension, so that it is advantageous to arrange the disk elements in the wall element as possible outside. Consequently, the profile frame should not protrude significantly beyond the outer surfaces of the disc elements. Advantageously, the distance between the two glass panes received in the profile frame has a value of at least 50 mm, preferably a value of at least 60 mm and particularly preferably a value of at least 80 mm, wherein the wall element does not exceed a total thickness of 100 mm.

A possible embodiment of the profile frame has vertically extending side frame parts, which are combined in the manner of a tongue and groove connection such that a plurality of wall elements can be arranged side by side and form a positive connection. Consequently, a wall element has a first vertically extending side frame part on a first Side, which comprises a groove, wherein the opposite second vertically extending frame part on the second side has a spring geometry. In the tongue and groove joining geometry, in turn, sealing elements can be provided to improve the sound insulation. The profile frame consists on the upper side of a horizontally extending upper spar and on the bottom side on a horizontally extending lower beam. As a result, a mostly rectangular profile frame is formed, wherein the vertically extending side frame parts are connected to the respective upper and lower rails. The connection can be made by angle profiles, which can be made of a stronger material, such as a steel material, since the weight of the disc elements is supported by the angle profiles, because the wall elements are usually taken with a guide device attached to the ceiling of the room is. Such wall elements may have heights of over four meters, so that when two glass sheets used in the profile frame of greater thickness, a considerable weight arises, which is first taken up by the lower beam and is introduced via the angle profiles in the vertically extending side frame parts.

According to the present invention, the partition wall on a sound insulation device, which is arranged in the upper beam and / or in the lower beam. The sound insulation device has sealing elements, which are each movable from the upper beam against the ceiling and from the lower beam against the ground. The sealing elements must be arranged movable in the upper and lower spar, since the sealing elements are moved only after reaching the final position of the wall element in the partition wall against the ceiling and the floor. Consequently, the wall element can be moved within the guide device without the sealing elements sealing against the ceiling and the floor.

For moving the sealing elements, the invention provides that in a wall element, a first drive unit in the upper spar and a second drive unit is provided in the lower beam, which moved separately from each other a respective sealing element both against the ceiling and against the floor. In contrast to conventional wall elements in which a single drive unit moves both a first sealing element against the ceiling and another second sealing element against the floor, the wall element according to the invention has separate drive units for the sealing elements for sealing against the ceiling and against the floor. In order to provide the inventive design of the wall element with a profile frame in which the drive units are introduced on the top and bottom, the drive units must be adapted to the available space within the upper spar and the lower spar. An alternative embodiment of a drive unit may comprise a spindle system which has only one drive, which is integrated in one of the vertically extending side frame parts, and cooperates both with the cover-side and with the bottom-side sealing element. Only then can the drive of the sealing elements on the upper side and underside be reduced to a drive unit. Regardless of the arrangement of the drive unit in the side frame parts or in the upper and lower beam this has been displaced at least from the middle of the wall element. Consequently, the transparency through the wall elements is not hindered by the arrangement of the drive unit.

Advantageously, the profile frame is determined by a width which does not exceed a value of 200 mm, preferably a value of 150 mm and particularly preferably a value of 120 mm. Only in this way can it be ensured that the side surface of the wall element is predominantly formed by the disk element. In particular, the parapet height from the bottom to the top of the profile frame in the region of the lower spar is limited to a value of 120 mm, with a small width of the profile frame contributes to a desirable, filigree appearance of the partition.

In an advantageous embodiment, the clip strip on the side of the sub-spar can be made in one piece with the lower beam, so that the disc elements can first be inserted or adjusted in the lower-side clip strip. Subsequently, the clipists are used on the side frame members as well as on the upper spar to secure the disc member in the profile frame. The clipists, which are arranged on the vertically extending side frame parts and on the upper spar, have a U-shaped extruded profile. The U-shaped extruded profile causes with a first U-leg a positive connection in the side frame part, and generates with a second U-leg a pressure of the disc element against the profile frame. This second U-leg is made longer with respect to the first U-leg and extends in sections over the disc element. In order to allow elastic reception of the disc elements in the profile frame, plug-in seals are provided which cooperate with the clamping strips. The plug-in seals are pressed on the entire circumference of the profile frame between the second leg of the clip strip and the disc element, and can lock in the clip strip. The male seals may be made of a rubber-like material to provide both a seal against contaminants that may get between the disc elements, as well as allow compliance between the profile frame and the disc element, for example, to compensate for thermal expansion.

The wall element has a total thickness of about 100 mm. This reduces the stacking height of the wall elements in a parking position. Furthermore, a smaller thickness of the wall element contributes to a filigree appearance, wherein it is also desirable to accommodate the disc elements with a large distance from each other in the profile frame. Consequently, the clipists have only a small height above the disk element, which is smaller than the thickness of the disk element, so as not to unnecessarily increase the total thickness of the wall elements.

Further, measures improving the invention will be described in more detail below together with the description of a preferred embodiment of the invention with reference to FIGS.

In FIG. 1 is a perspective view of a wall element 1 is shown. Several of these wall elements 1 may be adjacent in a room be arranged together to form a partition. To move the wall elements 1, they have a guide device 2, via which the wall elements 1 are movable in a rail system that is integrated, for example, in the ceiling of a room. The guide device 2 has a plurality of rollers which either run only for guiding the wall element 1 in the rail system or can be driven to form an automatically movable partition. The wall element 1 essentially comprises two transparent disc elements 3 which are arranged at a parallel distance from each other and which are received in a profile frame 4. The profile frame 4 has a rectangular shape and surrounds the disc elements 3. As shown in the perspective view of the wall element 1, the profile frame 4 forms only a small part of the side surface of the wall element 1, so that the width B of the profile frame 4 only a small proportion the lateral overall dimensions of the wall element 1 occupies. The profile frame 4 has two vertically extending side frame parts 4a and 4b, which are connected via an upper leg 4c on the upper side and a lower leg 4d on the lower side of the wall element 1. In FIG. 2 follows a cross-sectional view in the cross-sectional plane II-II, which is placed through the lower beam 4d.

FIG. 2 shows the cross-sectional view through the wall element 1 in the region of the sub-spar 4d according to the section II-II FIG. 1 , In cross section, the disc elements 3 can be seen, on the left side a thin and right side a thicker disc element 3 is used, which are arranged at a distance from each other. The distance of the disc elements 3 to each other is determined by the width of the profile frame 4. In this case, the disc elements 3 are accommodated as possible at a great distance from each other within a profile frame 4, which is reinforced by a cover band 10, to compensate for the smaller thickness of the disc element 3 on the left side.

Within the lower rail 4 d of the profile frame 4, a sound insulation device 5 is integrated, which has at least one sealing element 8 which is movable by means of a drive unit 9 against a bottom 11. The sealing element 8 consists at least of a rubber lip, which extends in addition to other sealing elements 12 over the entire width of the wall element 1 away. The sealing elements 8 and 12 are received in a receiving frame 13 which is vertically movable by the drive unit 9 against the ground.

The lower beam 4d has on the outside Clipleisten 6, which are made in one piece with the lower beam 4d. The clamping strips 6 have a U-shaped cross section, so that the disk elements 3 can first be inserted into the clamping strips 6. Due to the lower-side arrangements of the clamping strips 6, the disk elements 3 are held therein by their gravitational force, so that subsequently a plug-in seal 7 can be inserted between the clip strip 6 and the disk elements 3 in order to finally receive the disk element 3 in the profile frame 4. A detailed view of the arrangement of a plug-in seal 7 in the clip strip 6 is according to the detail III in the FIG. 3 shown in more detail.

FIG. 3 shows a detailed view of the detail III FIG. 2 , The clip strip 6 is part of the sub-spar 4 d, and has a leg which extends on the outside over the disc element 3 away. At the end, the clip strip 6 has a latching geometry 14, by means of which the plug-in seal 7 can be held. This has a recess 15 into which the nose-like locking geometry 14 of the clip strip 6 can hook. Consequently, it is possible to press the plug-in seal 7 between the clip strip 6 and the disc element 3, wherein the plug-in seal 7 is shown in the undeformed state, and the deformation takes place such that the plug-in seal 7 presses against the surface of the disc element 3.

The FIGS. 4a and 4b show a cross-sectional view of the profile frame 4 in the region of the side frame parts 4a and 4b. In the FIG. 4a is a cross section of the left side arranged side frame part 4a and in the FIG. 4b a cross-sectional view of the side frame part 4b of the profile frame 4 is shown. The side frame part 4a is designed as a groove part, whereas the side frame part 4b forms a spring part which is intended to engage in the groove part 4a of an adjacent wall element. Further sealing elements 16 and 17 are arranged in the tongue and groove geometry in order to make even the joint between the wall elements themselves soundproof.

The view also shows two disc elements 3, which are received at a distance from each other in the side frame part 4a and 4b. The recording takes place via clamping strips 6, which act in the same way with a plug-in seal 7, as already shown by the inclusion of the disc element 3 in the region of the sub-spar according to the FIG. 3 is described. However, the clamping strips 6 in the region of the side frame parts 4a and 4b are designed as individual parts, and have a U-shaped configuration with a short and a long U-leg. The short U-leg engages positively in a geometry of the side frame part 4a and 4b, so that the long U-leg extends over a portion on the disc member 3 away. At the end of the long U-leg of the clip strip 6, in turn, a plug-in seal 7 is inserted, which is designed in the same way as the plug-in seal 7 in the region of the sub-spar.

The FIG. 5 shows a detailed view of the arrangement of the clip strip 6 on the side frame profile 4a according to the detail IV FIG. 4a , The disc element 3 shown here is designed to be thinner, so that in the receiving geometry of the side frame part 4 a a decorative band 10 is used to compensate for the width of the receiving recess for receiving the disc element 3.

The connection between the plug-in seal 7 and the clip strip 6 takes place in the same way via a latching geometry 14, which is formed on the clip strip 6 and engages positively in a recess 15 which is present in the plug-in seal 7. The plug-in seal 7 has an elastic material such as a rubber band and the like, so that this can deform and causes a contact pressure of the disc element 3 against the cover strip 10 or against the profile frame 4 by the deformation.

The invention is not limited in its execution to the above-mentioned preferred embodiment. Rather, a number of variants is conceivable, which makes use of the illustrated solution even with fundamentally different types of use. In particular, the disk elements 3 may also consist of a polarization glass in order to temporarily suspend the transparency of the disk elements with appropriate electrical wiring. Furthermore, a special gas can be introduced between the two disk elements 3, which enables improved insulation properties for sound insulation. The material of the profile frame 4 may be an aluminum extruded profile, which may also be made split and includes a plastic bridge to provide a thermal insulation between the two outer surfaces of the wall element 1.
