Description

The invention relates to a fastening device for a sun protection element, in particular for a sun visor, which is designed to be fastened to a support element, in particular to a support profile of a facade element.

For reasons of sun protection, it is known to provide building facades and in particular facade elements with sun protection elements such as sun visors, wherein the sun visors must be fixed to the load-bearing elements of the building facade. Sun protection elements of this type can be designed to be fixed at one location and in one position, or the sun protection elements can be made adjustable with respect to their angle of attack.

As a rule, such sun protection elements are fixed directly to these support elements, for example at specially provided holes in the support elements or the like.

Conventional solutions for attaching a sun protection element to a support element have the disadvantage that the positioning of the respective sun protection element in the extension direction of the support element is determined by these optionally factory-mounted holes. Furthermore is a subsequent variable fine adjustment of the position of a once mounted sun protection element in the conventional solutions not possible.

The document US 2005/284053 A1 relates to a fastening device which is suitable, inter alia, for fastening a sunshade element. For fastening a channel for the penetration of hex nuts is provided, which, if necessary, can be brought into engagement with a Gegenarretierungselement. The locking on a carrier profile takes place at an angle of 90 °.

The present invention has for its object to provide a fastening device for a sun protection element, which allows a high flexibility of the sun protection element at the installation.

The object is achieved by a fastening device with the features of independent claim 1.

In particular, the object is achieved by a fastening device for a sunshade element, in particular for a sun visor, on a support element, in particular on a support profile of a facade element, wherein the fastening device delimited by at least one rear channel boundary and by a front channel wall mother channel for on-demand at least one Gegenarretierungselement in the mother channel and at least one slot in the front channel wall, wherein the slot in its extension direction allows variable positioning of at least one Gegenarretierungselementes, wherein the fastening device further comprises at least one passage opening for at least one fixing element for fixing the position of the fastening device on the support element ,

In this case, the mother channel extends in the longitudinal extension direction of the essentially a cuboid fastening device, and the slot is formed in the simplest case in the form of a simple groove, so that a possible displacement, so a variable positioning of the at least one Gegenarretierungsmittels within the mother channel is made possible by the mother channel is at least partially accessible through the slot from the outside.

The advantages of the solution according to the invention are obvious. Thus, by the variability, ie by the variable and externally enabled positioning of the at least one Gegenarretierungselementes along the Hauptausdehnungsrichtung of the channel, ie also along the extension direction of the at least one elongated hole a position of the Gegenarretierungselementes for engageable with the sunscreen element to be fastened fastener allows a variable position within limits, so that a Fine positioning and a fine adjustment of the solar protection element to be fastened to the support element is easily possible.

Furthermore, the fastening device according to the invention is possible in a simple manner on existing support elements, thus in particular on existing facade elements.

In particular, with common or standardized hole spacing on the support elements such as support profiles or the like is by forming the at least one passage opening on the fastening means a simple fixing of the fastening device at the installation site, d. H. ensured on the support element, at the same time the flexibility is ensured in terms of the positioning of the sun protection element by the use of the fastening device according to the invention.

Advantageous developments of the solution according to the invention are specified in the subclaims.

For example, it is provided that the at least one counter-locking element is a hexagonal counter-nut and is rotationally fixed on opposite surfaces of the nut channel by lateral channel boundaries.

For example, the mother channel can be formed by appropriate choice of its width such that common hexagonal counter-thread nuts of a certain size, such as counter-thread nuts size M8, are accurately inserted into the mother channel and rotationally fixed by the lateral channel boundaries, so be countered. In this case, therefore, no tool for preventing the rotational movement is necessary as soon as a fastener such as a threaded bolt is passed through the at least one elongated hole and inserted into the hexagonal counter nut, for example, to subsequently attach a sun protection element thereto.

Furthermore, it can be provided that two fastening elements are provided on the fastening device, wherein the distance between the fastening elements can be adapted to a hole spacing of the sunshade element by moving and then locking in the slot.

In other words, in sun protection elements, which are fixed to more than one suspension point per attachment device, a flexible adaptation to different hole spacings (Verschraubungsabstände) of various types of sun protection elements can be achieved by varying the distance between the fasteners.

Furthermore, it can be provided that the mother channel has a channel stop, which is preferably formed on the at least one rear channel boundary. An at least one fastening element that can be brought into engagement with the at least one variably positionable counter-locking element is designed for at least temporarily fixing its position as required after being engaged with the at least one counter-locking element, at least in regions, with the channel stop in a connection inhibiting the displacement.

Such a suitable Gegenarretierungselement is in the simplest case, for example, a threaded bolt, which is provided with an external thread, which corresponds to the internal thread size of the at least one Gegenarretierungselementes, so for example the hexagonal counter-nut. Such trained as a threaded bolt fastener is in this case then brought by simply screwing through trained as a hexagonal counter nut nut Gegenarretierungselement in the displacement inhibiting connection with the channel stop and can thus be fixed in the extension direction of at least one elongated hole in position. This fixed position then corresponds to a desired position of the sun protection element to be fastened, such as a sun visor or the like.

Furthermore, it can be provided that the fastening device also has a lower channel boundary and / or an upper channel boundary. The lower channel boundary or the upper channel boundary is or are designed to hold a counter-locking element let into the mother channel or a plurality of counter-locking elements let into the nut channel before engaging with the fastening element or the fastening elements in the mother channel.

In other words, in the mother channel recessed Gegenarretierungselemente can thus be protected against being lost, for example, during transport of a suitably prepared and not yet fixed to a support member fastening device. It must therefore be ensured that the arrangement of the lower channel boundary or the upper channel boundary is such that a displacement of the Gegenarretierungselemente in the at least one Slot is not obstructed. Ideally, the channel boundary or the channel boundaries are in this case formed outside the effective displacement region of the at least one elongated hole, ie, for example, in relation to the main expansion direction of the fastening device above or below it.

In this context, it may be provided that the channel boundary has a channel limiting opening for penetration into the mother channel and an auxiliary plug, for example, preferably pluggable insertable through the channel limiting opening. As a result, a very simple preparation and subsequent transporting the fastening device according to the invention to the support element is possible, namely by an auxiliary bolt is brought into the corresponding channel boundary opening for securing the introduced into the mother channel Gegenarretierungselemente.

It can be provided that the fastening device is at least partially formed from aluminum. As a result, a simple production, for example, in an extrusion process is possible, in particular, when the fastening device is to be fixed to a support member, which is also formed of aluminum, ensures a favorable visual appearance.

But it may equally well be provided as an alternative that the fastening device is at least partially formed from a plastic material. This makes it possible, the fastening device easier and cheaper produce, without the variable positioning of the at least one Gegenarretierungselementes and thus the sunscreen element to be attached is impaired.

in perspective view steps in chronological order for fixing the fastening device from the Fig. 1a to 1e according to the embodiment of a support element.

The FIGS. 1a to 1e show in perspective view the individual steps for preparing a fastening device 10 for a sun protection element before transport to a possible installation location, ie for example to a facade or the like.

As in Fig. 1a shown, the fastening device 10 along its main extension direction on a mother channel 13, which at the in Fig. 1a position shown from above and from below is accessible. The mother channel 13 is bounded to the front by a front channel wall 18, in which a slot 15 is formed in the form of a groove, which allows partial access to the mother channel 13. The side of the mother channel 13 is limited by the side walls of the fastening device 10; to the rear, a rear channel boundary 19 is given by correspondingly formed projections of the fastening device 10 formed as a profile.

In the expansion direction of the nut channel 13 above and below offset from the slot 15 channel limiting openings 31 a, 31 b are provided, in which, as in Fig. 1b shown, optionally pluggable auxiliary bolts 30a, 30b are introduced, so as to a lower channel boundary 32a and an upper channel boundary 32b (as described below in Fig. 1d shown). The auxiliary bolts 30a, 30b may for example be formed clampable or provided with a corresponding thread.

As in Fig. 1c In the following, counter-locking elements 12 in the form of hexagonal threaded nuts are introduced into the nut channel 13 and, as in FIG Fig. 1d shown in the position of the fastening device 10 shown there also secured against accidental loss from the mother channel 13. In Fig. 1e Finally, the ready for transport prepared fastener 10 is shown with inserted into the nut channel 13 Gegenarretierungselementen 12.

Like the sectional drawing Fig. 2 can be seen, the appropriately prepared fastening device 10 is attached to a support member 50 such as a vertically extending support post of a facade element in the following. Taking recourse to the representations in the FIGS. 1a to 1e For this purpose, in the fastening device 10 according to the invention a plurality of passage openings 21 are formed for fixing, said fixing elements 20 for fixing the fastening device 10, for example, with correspondingly formed counter-bores of the support element 50 can be brought into engagement.

The sequence of these steps is in the FIGS. 3a to 3e shown in perspective. For fixing the fastening device 10 according to the invention to a carrier element 50 designed as a carrier profile, as in FIG Fig. 3a represented, in each case fixing elements 20 guided by the corresponding passage openings 21 in the direction corresponding to the carrier profile 50 trained fixing points and as in Fig. 3a shown, bolted accordingly.

Thus, after fixing the position of the fastener 10 to the support member 50, as shown in FIG Fig. 3b shown, fasteners 11 in Inserted form of threaded rods with external thread in the located in the mother channel 13 Gegenarretierungselemente 12 and initially loosely screwed. The formed by the side walls of the fastening device 10 lateral boundaries of the nut channel 13 in this case prevents the rotation of trained as hexagonal Gegenarretierungselemente 12 in the nut channel 13 so that these hex nuts do not need to be secured separately against turning during the insertion process of the fasteners 11.

In Fig. 3c Finally, the so far still loosely located in the Gegenarretierungselementen 12 fasteners 11 are shown. As in Fig. 3d indicated, then the distance between the fastening elements 11 can be changed along the extension of the elongated hole 15 and, for example, the screw spacing or the like adapted to be attached sunscreen element. Furthermore, within certain limits along the extent of the elongated hole at the selected distance of the fastening elements 11 whose (common) absolute position can also be varied accordingly.

How finally in Fig. 3e shown, the fasteners 11 are then further screwed into the Gegenarretierungselemente 12 and then encounter a in Fig. 2 visible channel stop, whereby their displacement along the extension direction of the elongated hole 15 is inhibited accordingly. To finally secure the position of the fasteners 11 may - as also in Fig. 2 shown - another fuse element 16 come in the form of another lock nut used, which is screwed from the outside on the fastener clamped against the front channel wall 18 of the nut channel 13.
