Description

field of invention

The invention relates to a holder for attaching objects to adhesive substrates without drilling holes, and in particular to a holder which is suitable for attaching a large number of different objects. The invention relates in particular to a holder suitable for fastening venetian blinds or roller blinds directly to a window surface or a window frame or a door frame.

State of the art

From the DE 20 2018 106 139 U1 a clamp carrier is known which, when used in pairs, is used to hang sun and privacy protection devices and which can be placed with a support body with two clamping cheeks on an upper transverse beam of a window or door leaf. Such a clamp support is used for direct attachment, in particular of roller blinds and blinds, in particular to window frames, with the clamp support being clamped in the window frame. Such known clamp carrier are, however, disadvantageously limited to window frames that match their dimensions. Furthermore, such clamping brackets disadvantageously require the clamping of a window seal, which can impair the sealing effect with regard to noise and temperature. Likewise, a relatively limited diversity of the roller blind holder is available for use due to the dimensions of the receptacles provided on the clamp carrier. This limits the application to a specific geometry of suitable objects to be fastened. Furthermore, the positioning of roller blinds on window frames is not variable due to the fixed distance to the clamp, especially vertically.

From the EP 1 338 228 B1 a fastener is known by means of which curtain rods and the like can be fastened to walls or window frames. The fastener includes a base member having a mounting surface and a bearing surface extending perpendicularly from the mounting surface. The fastening means also has a clamping element for fixing a profile element lying on the bearing surface to the base element. An adhesive film strip is applied to the surface of the fastening surface, which is opposite the bearing surface, for bonding the fastening means to an adhesive surface, the adhesive film strip being detachable by stretching in the direction of the bonding plane. However, only low holding forces can be achieved with such adhesive film strips, and the adhesive film strips also have inadequate durability, especially when loads are applied, such as occur during assembly and also in the routine handling of roller blinds or venetian blinds. Furthermore, the geometry of the clamping elements disadvantageously restricts the application to certain suitable objects. From the DE 10 2009 008 461 A1 discloses a cord tensioner fastening device on a sliding curtain that is guided on at least two guide cords that run parallel to two first frame pieces of a window, in which both ends of each guide cord are each fastened with a cord tensioner on the two second frame pieces of the window that run transversely to the first frame pieces. To attach one of these also from the DE 10 2009 008 461 A1 An adhesive backing is provided for the proposed suitable cord tensioner on the frame of a window. The cord tensioner attachment device is disadvantageously limited to attachment of the cord tensioner and not suitable as a universal bracket.

From the WO 2019/141 969 A1 a mounting device with a mounting element and a cover for a fastening means of an object to be mounted is known, in which the mounting element is fixed to a mounting surface by means of an adhesive pad and a pin arrangement, the pin or pins intended to bear the weight of the object to be mounted and the Adhesive pad to prevent movement of the pins in relation to the mounting surface. The mounting device is modular with the mounting member and the cover corresponding to the mounting member so as not to be limited to mounting a simple hook but to be suitable for various fasteners. For this purpose, there are disadvantageously different mounting elements and covers designed individually for different fastening means.

From the DE 20 2009 000 057 U1 a mounting system for attaching mounting elements to a substrate is known, which includes a fastening element with a plate-like base body. The base body has a recess that is open towards the subsurface for receiving an adhesive between the subsurface and the fastening element. For a connection to the mounting element, the base body has a polygonal recess on its side facing the substructure for positively accommodating a screw head, the head of the screw being positively received in the polygonal recess and the shank of the screw extending through a central bore of the base body. A holding element with a suitable mating thread can be screwed onto the thread of the screw protruding through the central bore of the base body. The possible applications of the mounting system are accordingly limited. A nut to be attached to the outside of the mounting system, which is correspondingly disadvantageous, is provided for fastening objects with a hole. A corresponding plurality of mounting systems are disadvantageously required for fastening objects with more than one hole.

task

The object of the invention is to provide a holder for fastening objects to adhesive substrates without drilling holes, which is suitable for fastening a large number of different objects and in particular for fastening blinds or roller blinds, in particular directly to a window surface or a window frame or door frame. The bracket should be particularly desirable enable easy use when attaching objects as intended.

solution

This object is solved by the invention with the features of the independent claim. Advantageous developments of the invention are characterized in the dependent claims and in the subordinate claims referring back to the independent claim. The wording of all claims is hereby made part of the content of this description by reference. The invention also includes all reasonable and in particular all mentioned combinations of independent and/or dependent claims.

Individual method steps are also described in more detail below. The steps do not necessarily have to be carried out in the order given, and the method to be described can also have further steps that are not mentioned.

The present invention relates in particular to a universal mount for attaching an object to a substrate with a holder element and an adapter, the holder element being provided and suitably designed for attachment to the object, and the adapter being provided and suitably configured for attachment to the substrate with an adhesive is. Such separations of a holder into its elements, namely a holder element and an adapter, are advantageous, in particular also because of their different function, after which the elements separated from one another can be designed in a correspondingly functionally optimized manner.

The holder element of the universal holder is particularly advantageously designed as a housing suitable for the adapter in such a way that the holder element can be pushed onto the adapter glued to the adhesive base. This enables a particularly simple assembly of the universal bracket. The adapter is suitably accommodated in the interior of the housing and can be fixed in a form-fitting manner, so that the holder element is particularly securely fastened to the adapter.

The housing of the universal mount has a frame with a cover and a side opening, with a first rail-like receptacle for accommodating the adapter being provided inside the housing. It can be advantageous here that the adapter is designed in such a way that the adapter glued to the adhesive base has an edge that is spaced apart from the adhesive base. With this design of the housing and the adapter, the housing can also be pushed onto the adapter by hand in a particularly simple manner, even with an object already attached to the housing, without the use of tools.

The adapter can suitably be designed in the form of a plate and on its side facing the adhesive base there can be a recess for receiving the adhesive, which is delimited by a peripheral edge and which is also particularly advantageously spaced from the lateral edge of the adapter and which acts as a Adhesive edge can be formed. In particular, the edge designed as an adhesive edge has a particularly advantageous multiple function. The edge limits namely first in a simple way Recess for receiving the adhesive. Furthermore, the edge forms the distance between the primer and the side edge of the adapter. Finally, the adapter can be pre-positioned in a simple manner by means of the adhesive edge before introducing an adhesive which is present in a free-flowing form into its intended recess.

It is advantageous that the adapter, which can suitably be provided by means of a sintered metal plate, can have a suitable insertion opening for introducing the adhesive into the recess and also an outlet opening for escaping air and excess adhesive. Instead of the adapter, consisting of a sintered metal plate, it is also conceivable to fix the adapter completely with double-sided adhesive tape and thus also to use other materials. In this embodiment, the adhesive is provided by means of the double-sided adhesive tape.

On the lower edge of the frame of the housing, webs can be provided which extend into the interior of the frame and which in a simple manner form the first rail-like receptacle for accommodating the adapter in the housing. The webs can advantageously be designed in such a way that when the holder element is pushed onto the adapter, in particular by hand, they can be clamped under the edge of the adapter spaced apart from the adhesive base. In this way, the housing is particularly securely attached to the adapter.

The above universal bracket according to the invention has at least one screw and at least one nut for fastening the object to its holder element, wherein the Cover of the housing providing the holder element has at least one rail-like recess for a screw, within which the screw can be displaced and positioned laterally.

Inside the housing there may suitably be provided a second rail-like seat for accommodating a nut, within which a nut, like a protruding screw, is also slidable and laterally positionable in its rail-like recess. A hexagonal nut and particularly advantageously a square nut can be provided as the nut, which can be introduced, moved and positioned in a rail-like receptacle in a particularly simple and reliable manner.

The protruding rail-like recess for the screws is arranged and designed to correspond to the second rail-like receptacle for accommodating a nut in such a way that a screw suitably positioned in the rail-like recess can be inserted from outside the housing into one arranged inside the housing and suitably in the second rail-like receptacle positioned nut can be screwed.

The above measures create the possibility of adapting the universal mount to the object to be fastened to the housing by means of the screw by means of a corresponding displacement of the screw in the housing. The universal mount designed in this way is therefore particularly advantageously suitable for fastening a large number of differently designed objects in an optimized manner individually adapted to the object.

By means of the advantageously possible displacement of the screw, a universal mount that has already been installed can also be readjusted in a simple manner, if necessary.

The first and second rail-like receptacles for accommodating the adapter and the nuts can suitably be arranged laterally next to one another essentially in one plane, so that a particularly flat universal mount with a housing with a flat overall height is provided. The first and second rail-like receptacles can each be formed by first webs and second webs, each of which extends into the interior of the frame at the lower edge of the frame on opposite sides of the frame, and which each correspond to first and second webs which are provided on a partition wall between the first and second rail-like mounts inside the housing. It is clear that more than one second rail-like seat can also be provided for accommodating the nuts, for example two opposite sides of an adapter can each be arranged adjacent to screws and nuts in their corresponding recesses and seats described above.

The cover of the housing may further suitably have a central raised ridge, with the rail-like recess for receiving a screw and the second rail-like recess for accommodating a nut being formed in the ridge. The back can here have a cavity, and the second rail-like recess by means of opposing ones in the interior of the back extending webs may be provided. In this way, the screw and the nut are advantageously spaced apart from the first rail-like receptacle for the adapter.

According to a particularly advantageous embodiment, the universal mount can have two screws and two nuts and two rail-like recesses which correspond to a second rail-like receptacle, the rail-like recesses being arranged one after the other and being provided for receiving one screw each. This advantageously creates the possibility of adjusting the distance between the two screws by means of the screws that can be displaced in their rail-like recesses. The universal mount of this embodiment is therefore particularly suitable for attaching objects with the two holes provided for this purpose, with the hole spacing of the objects being able to vary in many ways. In this case, the two holes of an object are used by two correspondingly positioned screws for fastening the object to the holder element by the screws. Of course, it is also clear that the universal bracket of this embodiment can also be used for fastening an object with only one hole intended for a screw, correspondingly only one screw and nut being used on the holder element.

The two protruding rail-like recesses can be designed particularly advantageously in such a way that the screws that can be displaced in the recesses can have a spacing of 8 mm to 30 mm. In this way, the universal mount is suitable for a variety of different objects.

The lateral opening of the frame described above is provided in a suitable manner for pushing the holder element onto the adapter and for pushing a nut into the second rail-like receptacle, with the lateral opening being at least partially closed and the holder element being fixed on the adapter or the adapter in the Housing a locking clip is provided.

For this purpose, the locking clip can have a contour that can be locked in a form-fitting manner with the contour of the lateral opening and with the interior of the housing adjacent to the lateral opening. Particularly advantageously, the locking clip can have an actuating lever and latching elements arranged resiliently on the locking clip, so that the locking clip can be actuated by hand in a simple manner without tools and interacts with the housing. Here, not only is there a simple, tool-free assembly of the universal adapter, but also an equally simple, tool-free disassembly of the holder element by hand is possible.

The holder element forming the housing may suitably be of plastic eg ABS (acrylonitrile butadiene styrene copolymer) and the adapter may suitably be a sintered metal plate and the adhesive may be adhesive tape as described above or as also described above a moisture-curing adhesive, preferably SMP adhesive (silane-modified polymer). A screw with an M4 thread and a corresponding nut, in particular designed as a square nut, can be provided as a screw and a nut.

The holder element and the adapter and the adhesive and the screw with the nut can be designed in such a way that a permanent holding capacity of around 4 kg is achieved.

The invention therefore also relates to an advantageous set with a first and second universal holder described above for fastening elongate and/or heavy objects and/or objects which, when used as intended, are also exposed to regular loads. Fastening an object with two universal brackets results in a corresponding doubling of the holding power. Using such a set of two universal mounts, such objects can be attached particularly easily, in particular by hand without the use of tools, and also particularly securely.

The invention therefore also relates to an advantageous method for attaching an object to a substrate using a universal holder as described above, in which, in a first step, the adapter, which is pre-positioned on the substrate with its edge designed as an adhesive edge, is glued to the substrate using the adhesive. Here, when using a moisture-curing adhesive for the adhesive and a sintered metal plate for the adapter, the adapter is supplied with the adhesive through its insertion opening.

In a second step of the method, the object is screwed to the holder element, during the second step the adhesive used in the first step at least partially cured. It is particularly advantageous here that two process steps relating to the adapter and the holder element, namely the first step and the second step, can be carried out simultaneously, after which particularly rapid assembly is possible.

After the adhesive has hardened, in a third step, the holder element is pushed onto the adapter together with the object, and in a fourth step, which concludes the assembly, the holder element is fixed on the adapter by means of the locking clip. The third and fourth step can be carried out by hand in a particularly simple manner without tools.

The universal holder can be used particularly flexibly and is suitable for fastening a large number of different objects, e.g. for fastening in the bathroom, kitchen or workshop area, e.g. for fastening electric toothbrushes, shelves, shower baskets, strips (e.g. magnetic strips) for storing kitchen appliances, tools and the like Further possible uses are known to the person skilled in the art and are hereby made the subject of the description.

Since the universal mount, as described above, is also particularly suitable as a set for objects that are also regularly exposed to stress when used as intended, the invention also relates to the use of the universal mount or the set with two universal mounts or the above method for fastening a blind or a blind, particularly on a window or door. After blinds and roller blinds have an elongate dimension and, in addition to their own weight, can be subjected to regular loads and also heavy loads due to improper handling during their use, the above corresponding use is particularly suitable for blinds and roller blinds.

Further details and features emerge from the following description of preferred exemplary embodiments in conjunction with the dependent claims. The respective features can be implemented individually or in combination with one another. The options for solving the task are not limited to the exemplary embodiments. For example, range information always includes all - not mentioned - intermediate values and all conceivable sub-intervals.

Figure 1A shows a schematic representation of the elements of a universal mount 1 according to an embodiment of the invention with a holder element 2, a locking clip 3, an adapter 4 and two screws 5.

The holder element 2 is provided as a housing 2 for pushing onto the adapter 4 glued to an adhesive base and for accommodating the adapter 4 in the housing 2 . For this purpose, the housing 2 , which is open at the bottom and designed like a half-shell, has a frame 20 and a cover, which is provided with a central, raised back 200 . The frame 20 of the housing 2 has a side opening 23 through which the adapter 4 can be slid into the housing 2 . Nuts 50 provided for the screws 5 and corresponding to the screws 5 are also provided for accommodation in the housing 2 like the adapter 4 and can also be pushed into the housing 2 via the lateral opening 23 like the adapter 4 . The nuts 50 are advantageously designed as square nuts 50 .

A first rail-like receptacle 21 is provided in the housing 2 to accommodate the adapter 4 , and a second rail-like receptacle 22 is provided in the housing 2 to accommodate the nuts 50 . The first and second rail-like mounts 21 and 22 are described below with particular reference to FIG Figures 4A and 4B described.

For the arrangement and attachment of the two screws 5 on the housing 2 are in the back 200 in each case a first and second successive elongate rail-like recesses 25 are provided. The rail-like recesses 25 are designed and arranged in such a way that the screws 5 arranged in the recesses 25 extend with their thread into the interior of the housing 2 in order to be screwed there with the nuts 50 as intended. The screws 5 can be displaced laterally within the recesses 25 and positioned accordingly, with the spacing of the screws 5 being adjustable from 8 mm to 30 mm in this embodiment of the invention. It is clear that for this purpose the nuts 50 corresponding to the screws 5 can also be correspondingly displaced and suitably positioned in the housing 2 . By means of the spacing of the screws 5, which can be advantageously adjusted in this way, the universal mount 1 is suitable for fastening a large number of objects which have two holes, each with different spacings, for fastening them.

In addition to the rail-like recesses 25 for receiving and positioning the screws 5, further recesses 26 and 27 are provided in the cover of the frame 20 and the central raised back 200. The further recesses 26 and 27 are advantageously designed for a desirable weight reduction and material saving with nevertheless desirable rigidity and strength of the housing 2, which can be suitably provided in particular from plastic by means of injection molding. The recesses 26 also allow an advantageous view of the nuts 50 arranged in the housing 2 and thus facilitate their correct positioning.

The adapter 4 is plate-shaped and has, as best shown in Figure 1C shown on its side facing the adhesive base a recess 40 which is surrounded by an edge 41. The edge 41 is at a predetermined distance from the lateral edge of the adapter 4 , which is intended to rest on the first rail-like receptacle 21 of the housing 2 . The adapter 4 has an insertion opening 42 for introducing an adhesive, for example from a suitable tube or nozzle, into the recess 40 . In addition, the adapter 4 has an outlet opening 43 for the escape of air and excess adhesive when it is inserted into the recess 40 via the insertion opening 42 .

Figure 1B shows the elements of the universal mount 1 from Figure 1A composed and from a different perspective and Figure 1C shows the universal mount 1 from Figure 1B from another perspective, from which the side of the housing 2 and the adapter 4 facing the adhesive is visible.

The edge 41 is suitably an adhesive edge 41, which can be preserved on the adapter 4 by means of a peelable film, not shown in the drawings. The adapter 4 can be suitably pre-positioned by means of the adhesive edge 41 when it is attached to an adhesive base before the adhesive is introduced into the recess 40 . The thickness of the adhesive edge 41 corresponds to the first rail-like seat 21 suitably provided on the substrate-facing edge of the frame 20 and hereinafter with reference to in particular Figures 4A and 4B is described. The edge of the frame 20 facing the adhesive base has namely opposing webs 21 which form the first rail-like receptacle 21 and which are designed in such a way that they can be clamped under the edge of the adapter 4 when the housing 2 is pushed onto the adapter 4 already fixed to the adhesive base.

The locking clip 3 is designed to correspond with the lateral opening 23 and the adjacent housing 2 and frame 20 in a form-fitting manner. For this purpose, the locking clip 3 is designed such that it can be latched to the housing 2 and has two latching elements 31 which are provided on it in a resilient manner and which correspond to corresponding recesses in the housing 2 . The adapter 4 previously accommodated in the housing 2 is positively fixed by means of the locking clip 3 latched to the housing 2 . For this purpose, the locking clip 3 has a projection 34 which extends into the interior of the housing 2 and which corresponds to projections 24 on the frame 20 lying opposite it. For a particularly simple, tool-free actuation of the locking clip 3 by hand, the locking clip 3 has a lever-like actuating element 30 that covers the lateral opening 23 and is also suitable for disengaging the latched latching elements 31 by simply applying suitable pressure to the actuating element 30 by hand.

In this embodiment, the locking clip 3 is designed in such a way that it can advantageously completely close off the opening 23 .

Figure 2A shows a plan view of the universal mount 1 of FIG Figure 1B from above and Figures 2B and 2C show one each Side view of the universal mount 1 of Figure 2A . The adapter 4 housed in the housing 2 can be seen through the recesses 27 in the plan view of the universal mount. In addition, the as above with reference to Figure 1A nuts 50 described advantageously visible through the recesses 26, after which their correct positioning is particularly easy.

Both screws 5 are brought into a position in their rail-like recesses 25 in which they are each arranged at the end of the recess 25 spaced apart from the lateral opening 23 . It is clear that with this arrangement of the screws 5 a spacing of the screws 5 is provided which can also be provided with a large number of other positionings of the screws 5 . The arrangement of the screws 5 from Figures 2A and 2B with a screw 5, adjacent to the lateral edge of the housing 2 opposite the lateral opening 23, is particularly advantageous for objects designed correspondingly with this arrangement, since there is no vertical lowering even if the screws are loosened.

Figure 3A shows a section of the universal mount 1 along line AA of FIG Figure 2A and Figure 3B shows a section of the universal mount 1 along the line BB with a corresponding representation of the interior of the housing 2 with the adapter 4 arranged in the housing 2 and the screws 5 screwed into the nuts 50.

During the cut of Figure 3A goes through the screws 5 and the nuts 50, the section goes from Figure 3B through the lateral wall of the back 200 and shows the latching element 31 of the locking clip 3 latched in its latching position with a recess in the housing 2 . The adapter 4 is held and fixed in a form-fitting manner between the projection 34 of the locking clip 3 and the projection 24 provided on the inside of the frame 20 and lying opposite the projection 34 . The bolts 5 are fully threaded into the nuts 50 while being designed to be spaced from the surface of the adapter 4 . The screws 5 are suitably designed in such a way that although they still protrude into the nuts when the object is placed on them, they are still short enough not to hit the adapter and run the risk of damaging the housing if they are overtightened.

It is clear here that when the universal adapter 1 is used as intended with screws 5 passed through corresponding holes in an object to be fastened and then screwed with the nuts 50, the ends of the screws 5 protruding from the nuts 50 are correspondingly further spaced from the adapter.

The edge 41 of the adapter 4 protrudes as already in Figures 2B and 2C shown by a predetermined amount above the lower edge of the frame 20 of the housing 2, which will be referred to below with reference to FIG Figures 4A and 4B is described.

Figure 4A shows a section of the universal mount along line CC of FIG Figure 2A , and Figure 4B shows a cut of the universal mount 1 along the line DD. The first rail-like receptacle 21 is, as already with reference to FIG Figure 1C mentioned, provided by means of opposing webs 21 provided at the lower edge of the frame 20, the webs 21 of the mounted universal mount 1 being arranged adjacent to the adhesive base and being clamped under the lateral edge of the adapter 4 corresponding to the webs 21. The lateral edge of the adapter 4 is spaced from the adhesive base by a predetermined amount, which is specified by its edge 41 and is designed to provide the recess 40 and a pre-positioning of the adapter 4 on the adhesive base.

The first rail-like receptacle 21 formed by the webs 21 is delimited laterally by the frame 20 and its projections 24 and the projection 34 of the locking clip 3 and, as described above, interacts laterally with the adapter 4 in a form-fitting manner. This also applies to the webs 21 on which the lateral edge of the adapter 4 rests, the webs 21 clamped under this edge also interacting positively with the lateral edge of the adapter 4 .

The height H4 of the first rail-like receptacle 21 advantageously exceeds the thickness D4 of the adapter 4, as a result of which the housing 2 can be pushed onto the adapter in a particularly simple manner.

The second rail-like receptacle 22 formed by the webs 22 is from the opposite lateral walls of the spine 200 is limited, with the lateral dimensions of the rail-like receptacle 22 corresponding to the nuts 50 in a form-fitting manner. The nuts 50 lie on the opposite webs 22 and have a predetermined amount of play in the second rail-like receptacle 22 formed by the webs 22 parallel to the screws 5 and perpendicular to the adhesive base, after which the nuts 50 in the second rail-like receptacle 22 are advantageous easily moved and are protected against jamming.

A above with reference to Figures 1 to 4 The universal mount 1 described is designed to be particularly compact with the first 21 and second 22 rail-like receptacles arranged one above the other for accommodating the adapter 4 and the nuts 50 in each case. The universal mount 1 described is suitable for attaching a large number of differently designed objects and is particularly suitable for attaching blinds or roller blinds to a door or a window. A set of two universal brackets is particularly advantageous for the attachment of objects designed in this way, which, such as roller blinds and blinds, can also be exposed to a certain amount of stress during use.

Figure 5A shows a schematic representation of the elements of a universal mount 1 according to a further embodiment of the invention from two perspectives, each with a mount element 2, a locking clip 3, an adapter 4, two screws 5 and two nuts 50, the mount element 2 covering the housing 2 of the universal mount 1 forms.

Figures 5B and 5C show the universal bracket 1 from Figure 1B each assembled from a further perspective with a top view of the cover of the housing 2 in Figure 5B and the interior of the housing 2 in Figure 4C .

The universal bracket 1 from Figure 5A corresponds essentially to that referred to above Figures 1 to 4 described universal mount, which is why reference is made here to the above description.

Unlike the Universal Bracket 1 from Figures 1 to 4 is with the universal mount 1 from figure 5 the first 21 and second 22 rail-like receptacle arranged next to one another essentially in one plane, so that a particularly flat universal mount 1 with a housing 2 with a flat overall height is provided.

The first 21 and second 22 rail-like receptacles for accommodating the adapter 4 and the nuts 50 are each formed by first webs 21 and second webs 22, which each extend at the lower edge of the frame 20 on opposite sides of the frame 20 into the interior of the Frame 20 extend, and which correspond to first 21 and second 22 ridges, respectively, which are provided on a partition wall between the first 21 and second 22 rail-like receptacle inside the housing 2.

The side opening 23 is partitioned by the protruding partition wall, and the locking clip 3 is formed in this embodiment, for example, such that the opening 23 only partially closed, and the adapter 4 is fixed in the first rail-like receptacle 21 between its projection 34 and projections 24 inside the housing 2 .

The other features of the execution of figure 5 , such as the recesses 26 through which the nuts 50 are visible from outside the housing 2, correspond to the embodiment of FIG Figures 1 to 4 , which is why reference is again made to the above description in this regard.

Figure 6A shows the universal mount 1 from Figure 5B with the nuts 50 visible through the recesses 26 from above and below, and in Figure 6B two side views of the universal mount 1 are shown. The adapter 4 is fixed between the projections 24 and 34 inside the housing 2 . Figure 6C shows a section of the universal mount 1 through the lines AA and BB of FIG Figure 6A .

More cuts through the universal mount 1 from Figure 6A along lines CC, DD, EE and FF are in 7 shown, with the features of the adapter 4 with its recess 40, the edge 41, the insertion opening 42 and the outlet opening 43 on the above description of the embodiment of Figures 1 to 4 is referenced. This also applies to the actuating element 30, the projections 24 and the locking elements 31 of the locking clip 3. While in the sectional views of 7 along the lines CC, DD and in the partial section along the line FF the universal mount 1 with the housing 2, the screws 5, nuts 50, the adapter 4 and the locking clip 3 is shown, only the housing 2 with the frame 20 is shown in the section along the line EE.

The design of the universal bracket 1 from Figures 5 to 7 differs from the universal mount 1 of Figures 1 to 4 in that the first 21 and second 22 lateral receptacle for accommodating the adapter 4 and the nuts 50 are arranged side by side and are arranged essentially in one plane, so that a particularly flat overall height is achieved. As can best be seen from the sectional views DD and EE, the first rail-like receptacle 21 is advantageously designed in such a way that the adapter 4 is at a distance from the cover of the housing 2 . Furthermore, the second rail-like receptacle 22 is advantageously designed in such a way that the nuts 50 are arranged adjacent to the inside of the cover of the housing 2 and are correspondingly spaced from the substrate.

The execution of Figures 5 to 7 has, for example, a second rail-like receptacle 22 . It is clear that a modification of this embodiment can also have more than one second rail-like receptacle 22, for example on two opposite sides of an adapter 4.

The universal brackets 1 of the two versions of Figures 1 to 7 are suitable for fastening a large number of differently designed objects and are particularly suitable for fastening blinds or roller blinds to a door or window. The use of the universal bracket 1 of the execution of Figures 1 to 4 or the execution of Figures 5 to 7 can be made dependent on the extent to which e.g. aesthetic (e.g. not visible if possible) and/or functional (e.g. shallow depth) aspects predominate. In the former case, the use of the universal bracket 1 from Figures 1 to 4 and in the latter the universal mount 1 of Figures 5 to 7 to be favoured. A set of two universal brackets 1 of the design of Figures 1 to 4 and/or the execution of Figures 5 to 7 advantageous.

8 shows a flowchart of the essential steps of a method for attaching an object to a substrate according to an embodiment of the invention using the universal mount 1 with the steps S1, S2, S3 and S4.

In a first step S1, the adapter 4, which is pre-positioned with the edge 41 on the substrate, is glued to the substrate by means of the adhesive, with the adhesive being supplied to the recess 40 via the insertion opening 42.

In a second step S2, the object is screwed onto the holder element 2, with the adhesive used in step S1 curing at least partially during the second step S2. Particularly advantageously, two process steps S1 and S2, each relating to the adapter 4 and the holder element 2, can be carried out simultaneously, after which particularly rapid assembly is possible.

After the adhesive has hardened, in a third step S3 the holder element 2 is pushed onto the adapter 4 together with the object, and in a last step S4 concluding the assembly, the holder element 2 is fixed on the adapter 4 by means of the locking clip 3 . The third and fourth steps S3 and S4 can be carried out by hand in a particularly simple manner without tools.

Numerous modifications and developments of the exemplary embodiments described can be implemented.
