Description

The invention relates to a facade and / or Lichtdachkonstruktion with at least one specified on a substructure insulating glass, the edge is provided at least in some areas with a groove into which a support arm of a glass holder engages, which is secured to a screw groove having a connection profile of the substructure.
Especially with so-called all-glass facades of buildings, glass holders are needed which provide as inconspicuous as possible for a support of the insulating glass panes, wherein the glass holders are mounted either before mounting the insulating glass panes or even thereafter.
From the document WO 2004 063517 already such a construction is known.
The invention has the object of providing a facade and / or roof construction of the type mentioned in such a way that both the assembly of the glass holder and the subsequent attachment of the insulating glass elements can be done in a simple manner and in particular with conventional tools.
This object is achieved according to the invention in that the support arm is pivotally connected to an attachment base of the glass holder, wherein the attachment base has a substantially U-shaped connection element and is fixedly mounted with this on the connection profile.
The advantage achieved by the invention consists essentially in the fact that the glass holder can first be attached to the connection profile and then the actual fixing of the insulating glass pane can be carried out by the pivotally formed support arm.
In order to make the attachment of the glass holder on the connection profile particularly simple, it is proposed in the invention that the two legs of the connection element are provided on their inner surfaces with projecting ribs which engage in a toothing on the outer surfaces of the connection profile by clamping.
Further, it has proved to be advantageous in the context of the invention, when the attachment base carries a bearing bush on which the support arm is rotatably supported by means of a socket. As a result, the pivoting of the support arm is made possible in a simple manner.
It is particularly advantageous in this case if the bearing bush is provided with detents, which engages behind an annular shoulder on the inner circumferential surface of the plug-in sleeve. In this way, the glass holder can be particularly easy to assemble, moreover, even the possibility exists, first to mount only the top socket of the glass holder, only to then set up the support arm with the socket on the bearing bush.
For this purpose, it is further advantageous if the bearing bush is formed by spring blades, which are spaced apart by axially extending cutouts, wherein the latching pawls are arranged at the free ends of the spring blades.
It is further proposed in the invention that the socket are provided at its end facing the attachment base with sawtooth gate projections, which are assigned in the attachment socket correspondingly shaped sliding recesses, wherein the slide projections are aligned with the Kulissenausnehmungen so that they are in mutual engagement, if the retaining arm engages in the groove of the insulating glass pane. This ensures that upon rotation of the receptacle with the support arms, these are displaced in the direction of the substructure, causing the Insulating glass panes also experience a contact force in the direction of the substructure.
The link projections are advantageously arranged uniformly distributed over the circumference.
In order to ensure an accurate alignment of the support arms after mounting the insulating glass, it has proved to be useful if a stop bar is provided for an axially extending on the plug sleeve stop rib on the top pedestal. Thus, the socket can rotate only as far on the top socket until the support arm is aligned substantially perpendicular to the edge of the insulating glass pane.
The glass holder itself is advantageously secured by means of a self-tapping or furrowing, in the screw channel and coaxially extending in the socket screw on the connection profile, which is supported with its head in a receptacle of the receptacle.
The socket may have either a support arm or two stretched aligned to each other retaining arms, depending on whether it is mounted in the middle of a field of insulating glass panes or at the edge.
In order to achieve defined pressure forces, it is also advantageous if the holding arms are spherically shaped at their free end.
In the following the invention will be explained in more detail in an embodiment shown in the drawing; show it:

Fig. 1: a perspective view of a facade construction, only partially reproduced,
Fig. 2: in subfigures a to c the glass holder in not yet assembled state,
Fig. 3: one of the FIG. 1 corresponding representation, but without insulating glass panes and with mounted glass holder.

The only partially reproduced in the drawing facade construction represents a so-called all-glass facade, in which insulating glass panes 1 are enclosed on a reproduced here in the form of a pillar substructure 2, wherein on the outer surface no fastening elements for the insulating glass pane 1 can be seen. For this purpose, the insulating glass panes 1 are peripherally provided at least in some areas with a groove 3, in which a support arm 4 of a glass holder 5 engages, wherein the glass holder 5 is fixed to a screw groove having a connection profile 6 of the substructure 2.
In detail, the holding arm 4 of the glass holder 5 is pivotally connected to an attachment base 7 of the glass holder 5, so that the glass holder 5 can be mounted both before and after the attachment of the insulating glass panes 1, as shown in FIGS FIGS. 1 or 3 can be seen.
The attachment base 7 itself has a substantially U-shaped connecting element 8, with which it is firmly seated on the connection profile 6. These are the two Leg of the connecting element 8 is provided on its inner surfaces with projecting ribs 9, which grip in a toothing 10 on the outer surfaces of the connection profile 6 by clamping.
As can be seen in particular from the FIG. 2 can be seen, the attachment base 7 carries a bearing bush 11 on which the support arm 4 is rotatably supported by means of a socket 12.
The bushing 11 is provided with detents 13, which engages behind an annular shoulder 14 on the inner circumferential surface of the socket 12. Further, the bearing bush 11 is formed by spring blades, which are spaced apart by axially extending cutouts 15, wherein the latching pawls 13 are arranged at the free ends of the spring blades. As a result, it is possible to simply postpone the socket 12 to the bushing 11, whereby the spring blades deform temporarily to then intervene behind the annular shoulder 14 with their latches 13.
As is further from the FIG. 2 can be seen, the plug-in sleeve 12 is provided at its end face facing the attachment base 7 with sawtooth-shaped link projections 16, which are assigned in the attachment socket 7 correspondingly shaped link recesses 17. Through this gate projections 16 and Kulissenausnehmungen 17 an axial movement stroke of the receptacle 12 is achieved with respect to the bushing 11, whereby it is possible to achieve a contact pressure of the insulating glass pane 1 against the substructure 2 during assembly of the glass holder 5. For this purpose, the slide projections 16 to the Kulissenausnehmungen 17 be aligned so that they are in mutual engagement when the support arm 4 engages in the groove 3 of the insulating glass pane 1.
As can be seen further from the drawing, the slide projections 16 are arranged uniformly distributed over the circumference.
On top cap 7 a stop bar 18 is further provided for an axially on the socket 12 extending stop rib 19, which serves to ensure during assembly of the glass holder 5 that the support arm 4 in optimal alignment, ie aligned perpendicular to the edge of the insulating glass pane 1 is to ensure maximum retention of the insulating glass pane 1.
The glass holder 5 itself is secured by means of a self-tapping or furrowing, in the screw channel of the connection profile 6 cross-bolt 20, which extends coaxially in the socket 12. The socket 12 is for this purpose provided with a receptacle 21 in which the head of the screw 20 is supported. The arrangement of the screw 20 in the socket 12 can be made so that the socket 12 is taken when turning the screw 20 with Raibschluß, the support arms 4 so when turning the screw 20 automatically pivot into the groove 3.
In the embodiment shown in the drawing, the plug-in sleeve 12 has two support arms 4 aligned in an aligned manner; If the glass holder 5 is arranged on the edge of a façade surface, however, the socket 12 carries only a support arm 4. To this case To ensure defined pressing force, the support arms 4, as in the FIGS. 2a and 2b arranged, spherically shaped at its free end.
