Description

The invention concerns a fixing device for mounting wall elements for constructing a wall, said fixing device comprising: a support profile having a holding side for fixing the wall elements thereto;a securing element which is provided with an engagement element for engaging on the support profile for fixing the securing element to the support profile, and which is designed to extend between the wall elements; anda closing profile which is attachable to the securing element for holding the wall elements between the support profile and the closing profile. Such a fixing device is suitable for mounting a plurality of wall elements but may also be used for mounting a single wall element. Such fixing devices are typically used to divide larger rooms into smaller rooms, wherein for example meeting areas can be separated from office areas. The larger rooms are here divided by one or more wall elements such as glass panels and/or wooden panels etc. These fixing devices are not restricted to the construction of walls in interior spaces but are also used for erecting exterior walls. Such wall elements must be able to be erected quickly and flexibly and be removable again later. Fixing devices for mounting wall elements between said support profiles and closing profiles are known for example from DE 1 079290 B, DE 198 04 925 A1, EP 0 821 127 A2, AT 392 714 B, DE 41 07 743 A1, DE 196 51 365 A1, EP 0 652 335 A1, NL 1 016 724 C, DE 43 31 963 A1 US 4 098 555 A and DE 30 48 152 A1. The support profiles here must firstly be positioned precisely and securely. After positioning the support profiles, one or more wall elements are attached to the support profiles. Then various systems are known for fixing the closing profiles to support profiles. The wall elements must in each case be positioned and then firmly held either manually or by associated aids so as to be able to attach the closing profiles. DE 1 079 290 B and DE 198 04 925 A1 disclose fixing devices in which the closing profiles are attached directly to the support profiles by a click connection. In EP 0 821 127 A2, the closing profiles and the support profiles are click-fastened to one another by means of an elastic profile. This is however not straightforward with heavy wall elements. In EP 0 652 335 A1, embodiments are described in which the wall elements are first click-fastened by means of securing elements and then the support profiles are attached. In DE 43 31 963 A1, the closing profiles are fixed to the support profiles with a barbed connection. Such clip connections and barbed connections are typically only suitable for mounting lighter wall elements and/or horizontally lying wall elements, e.g. in order to create a lighting strip. If these click connections or barbed connections are however made sufficiently stiff to be able to hold heavy wall elements, in practice it is not easy to implement such a connection. AT 392 714 B, DE 41 07 743 A1, DE 196 51 365 A1, EP 0 652 335 A1 and NL 1 016 724 C describe and depict embodiments in which the wall elements are first screwed or bolted to the support profiles by means of securing elements so as to be able to hold the wall elements securely, whereafter the closing profiles are click-fastened to these securing elements. Mounting such fixing devices is relatively cumbersome. US 4 098 555 A describes a relatively complex fixing system in which a bolt is used comprising two coaxial parts which can be rotated relative to one another in order to be able to attach both ends of this bolt to corresponding profiles with respect to wall elements mounted in between. DE 30 48 152 A1 describes a fixing device according to the introductory part of claim 1. The object of the invention is to provide a fixing device by means of which such walls can be erected more easily but sufficiently securely, without the wall elements having to be held firmly in order to be able to attach the closing profiles. This object of the invention is achieved by providing a fixing device for mounting wall elements for constructing a wall, said fixing device comprising: a support profile having a holding side for fixing the wall elements thereto;a securing element which is provided with an engagement element for engaging on the support profile for fixing the securing element to the support profile, and which is designed to extend between the wall elements; anda closing profile which is attachable to the securing element for holding the wall elements between the support profile and the closing profile; wherein for fixing to the support profile, the securing element is rotatable relative to the support profile between: a first position in which the engagement element remains separate from the support profile so that the securing element is movable transversely on the holding side relative to the support profile; anda second position o in which the engagement element engages on the support profile so as to fix the securing element to the support profile,o
