Detailed description of the figures

Before the actual detailed description of the figures, general aspects and features of the adhesive mount and the perforation device will be explained.

In general, the adhesive-capable holder has an adhesive surface for receiving adhesive, which makes it possible to glue the holder to a target surface.

The adhesive surface is located on a base plate of the adhesive mount. It may be circular, but it may also be square or rectangular.

Attaching a bracket to a target surface, which is typically part of a wall or ceiling surface of a building interior or to a building exterior wall, is often accompanied by practical difficulties. As is well known, wall and ceiling surfaces made of masonry, concrete, wood or the like often have a plurality of wallpaper and / or color layers, some of which are not readily suitable for reliable bonding, solid surface. Even under such unfavorable conditions, a firm and secure attachment of brackets is desirable.

Preferably, the adhesive mounts described herein are configured to carry household or home furnishings. Thus, in one embodiment, at least two brackets hold a curtain or coat rack between them. In other embodiments, the holder includes a hook or the like to which household items such as towels or kitchen utensils can be hung. It is also conceivable to form the bracket as a curtain rail, which is attached over the length of a window across the ceiling extending.

In some embodiments of the holder, the adhesive surface receives an adhesive, which is applied to the adhesive surface, for example in the form of an adhesive layer. Alternatively, the adhesive is, for example, distributed pointwise over the adhesive surface. If such an adhesive layer is already applied by the manufacturer to the adhesive surface, the adhesive applied to the adhesive surface is often covered with a peelable film or a peelable paper to prevent accidental sticking of the holder or contamination of the adhesive. In other embodiments, which use, for example, a fast-drying adhesive, the adhesive is applied in one embodiment of the inventive method until immediately before attaching the holder to the target surface on the adhesive surface.

In order to accommodate larger amounts of the adhesive, the adhesive surface of the base plate in one embodiment, grooves or depressions. In some embodiments, an adhesion promoter is additionally used.

Since the holder is preferably used in household and furnishing area, for example to hold curtain rods or other furnishings, an adhesive is preferably used, which on normal building wall surfaces of masonry, plasterboard, concrete, wood or the like, which may be plastered or tiled, a wallpaper o. Ä. Are provided, ensures a satisfactory adhesive bond. Furthermore, it has frequently been found to be advantageous, for example, to use a water-soluble or heat-soluble or peelable or otherwise detachable adhesive, in order to permit residue-free removal of the holder from the wall or ceiling surface.

For example, if a heat-soluble adhesive is used, the adhesive can be melted by targeted heat (as can be exercised for example by means of a hair dryer) and thereby the adhesive bond can be solved.

Normally, the adhesive surface or base plate of the holder is rectangular, oblong or round. A round base plate makes an exact alignment with spirit level or the like unnecessary when sticking to the wall or ceiling surface. As a standard form, a rectangular base plate is often the easiest to manufacture.

However, the base plate may also have any other shapes, which are selected according to the later use and, for example, from an aesthetic point of view or in adaptation to spatial conditions. Mostly, the base plate - depending on the material used - a thickness of a few millimeters to a few centimeters: If the base plate made of metal or wood, for example, a thickness of a few millimeters is sufficient to ensure sufficient stability of the base plate; Plastic or glass base plates are often made slightly thicker, depending on the plastic used.

The base plate is not necessarily made flat; as long as the adhesive surface is suitable for application to a target surface, nothing stands in the way of its wedge-shaped or any deviating configuration, for example also in adaptation to a non-planar target surface.

On the base plate according to some embodiments, a receiving portion is arranged, which serves for fixing the object to be held on the holder. This receiving portion is in the simplest embodiment, for example, a hook, strap or knob to which an object, such as a towel or a decorative element such as a picture can be hung, or even a simple borehole o. Ä., With its help the object to be held can be screwed or fastened to the holder.

In other embodiments, the receiving portion is adapted to receive a rod-like member (or member to be retained with a rod-shaped portion) to be retained, such as a curtain rod. For example, the receiving section may then be a material cylinder a few centimeters high, which has centrally a recess running over its entire height or part of its height. This results in a ring which can receive in its center to be held, rod-shaped element. In adaptation to the cross-sectional shape of the rod-shaped element to be held, the receiving portion may also have a quadrangular or triangular or any other shape. When selecting the shape, manufacturing and aesthetic aspects must be considered. In such a configuration, the receiving portion can receive the rod-shaped element to be held, for example, in a plug connection. For this purpose, the dimensions of the receiving portion and the rod-shaped element are preferably adapted to one another in such a way that, when the plug connection is produced, a firm seating of the rod-shaped element in the receiving portion results. For example, the receiving portion has a size corresponding to commercial dimensions of curtain rods, for example.

Due to the tight fit in the production of the connector eliminates the need for additional screwing o. Ä. Between the rod-shaped element and the holder. Due to the frictional force, the rod-shaped element is held reliably under normal load without further attachment in the receiving section, but with the application of a corresponding frictional force exceeding force simply removed from the receiving section. In this case, the dimensions of the receiving section or the force which is necessary for producing or releasing the plug-in connection are preferably selected such that the rod-shaped element can be manually inserted into and removed from the receiving section.

In order to make the holder even safer and to prevent removal of the element received in the receiving portion by children, in one embodiment, an additional screw o. Ä. Of the recorded in the receiving portion element with the base plate or the receiving portion is possible. In other embodiments, a secure connection between receiving portion and rod-shaped element by means of a bayonet closure, a Threaded connection o. Ä. Guaranteed instead of a connector.

The receiving portion and the base plate are usually made in one piece or, for example, screwed together already factory or glued together. Thus, when mounting the article on site no assembly of the bracket is necessary. Normally, the receiving portion is made of the same material as the base plate, although another material may be used.

According to a further embodiment, the above-described, arranged on the base plate receiving portion is not designed to receive the object to be held directly, but rather one or more mediating holding pieces, which in turn holds / hold the object to be held. Thus, the receiving portion represent a rail or bar, can be hung in the appropriate holding pieces, as is the case with curtain rails. These matching holding pieces then in turn hold the respective objects to be held, for example in a clamping or spring connection.

In other embodiments, the mediating holding piece may be rod-shaped and received in the receiving portion of the holder in a plug connection. The arranged on the base plate receiving portion of this embodiment differs only by a previously described receiving portion for the direct reception of a rod-shaped element to be held, that its dimensions are preferably adapted to the holding piece and not to the element to be held. This results, for example, in the production of a plug connection between the receiving portion and retaining piece a tight fit of the support member in the receiving portion, without further fittings are necessary. Again, the dimensions of holding piece and receiving portion are preferably selected such that the holding piece for the production of the connector under application of a - not too large - force can be manually inserted into the receiving portion and removed from it.

Alternatively, bayonet locks or screw connections are also used instead of the plug connection here.

For a reliable attachment of a holder according to the invention described above on a wall or ceiling surface, the target surface is treated prior to bonding of the holder. For this purpose, a perforation device for the treatment of the target surface for the attachment of an adhesive mount is provided, which has an adhesive surface for receiving adhesive, which allows the attachment to the target surface. By means of the perforation device, the target surface of the wall or ceiling surface to which the support is to be attached, with several recesses or punches, e.g. in the form of holes, notches, slits, or the like provided. In this way, any material such as loose paint, wallpaper, wallpaper remnants and / or components of a wall plaster can be removed from the target surface, so that the target surface provides a solid base for the gluing of the holder.

If the adhesive surface of the holder is pressed in a next step on the target surface prepared in this way, the adhesive applied to the adhesive surface is distributed on the target surface and on any recesses which have a more or less strong penetration depending on the material of the wall or ceiling surface. In embodiments with softer wall materials, the recesses additionally provide an increase in the area with which the adhesive is in contact, which in turn increases the adhesive force provided by the adhesive.

Because in some embodiments, the recesses or punches, for example, as holes through one or more layers (such as wallpaper or ink layers) of the wall or ceiling surface, thereby a detachment of the wallpaper or paint layers made possible by the substrate, so that the holder directly on the solid ground Wall or ceiling surface can be glued. In other embodiments, the adhesive distributed in the recesses contacts one or more layers having a different structure from the surface of the substrate. Preferably, the depressions extend so deep into the wall surface, that the adhesive distributed in the recesses with the underlying base wall surface such as masonry, Rigips, Concrete, wood or the like, comes into contact. Therefore, even if the layer forming the target surface has poor adhesive properties, the depressions offer the possibility of at least partially utilizing the better adhesive properties of the underlying layers and / or the base surface. Moreover, the depressions reduce the risk that the uppermost layer forming the target surface (for example, when poorly connected to the underlying layer) can not support a weight which is hung on the support and breaks down together with the support: Since the adhesive is distributed in the recesses and thus possibly connected with several layers, not only spreads a weight acting on the holder on these multiple layers, but also holds the adhesive together the individual layers.

The depressions or punches in the target surface can be formed by means of a perforation device specially designed for this purpose. In particular, such a perforation device has one or more perforation elements for forming the depressions or punches in the target area. For example, the perforation elements are sharp-edged projections, pointy pins or nail-like elements. In order to form depressions of a desired depth and a desired diameter, the perforation elements have a diameter which corresponds to the desired diameter of the depressions, as well as a length which corresponds at least to the desired depth of the depressions, that is normally a few millimeters.

In one embodiment, the perforation device comprises a base area on which the perforation elements are arranged, preferably evenly distributed.

For example, the perforation elements are arranged on one side of the base surface, and the other side of the base surface is designed to provide a suitable contact surface for a force of suitable direction and then to transmit this force to the perforation elements.

For example, this attack surface is flat. An operator can then attach the perforation elements of the perforation device to the target surface and about with Hammer a hammer on the other side of the base until the perforation elements penetrate into the target area, which may also have wallpaper and / or color layers, and thus punch out depressions.

After the perforation of the target surface and the possible removal of wallpaper and / or color residues, the adhesive surface of the holder is pressed onto the target surface, so that the adhesive is distributed and produces an adhesive bond. Depending on the adhesive chosen, in one embodiment the pressure must be maintained for a predetermined period of time so that the adhesive bond can strengthen (such as by drying the adhesive). In one embodiment, in which a thermoplastic adhesive is used, the adhesive is heated during pressing, for example by means of a hair dryer.

There is also provided a set of a holder and a perforating device described above. Such a set includes, so to speak, the basic equipment for attaching one or more adhesive mountings.

In one embodiment of the sentence holder and perforation device are matched. Thus, for example, the size of the base area of the perforation device can be matched to the size of the adhesive surface of the holder: If, for example, a base area of the same size as the adhesive surface of the holder selected, is sufficient - as already described - a single perforation to the target area at which the Holder is to be attached to provide with recesses.

Alternatively, the base area of the perforation device is half the size of the adhesive surface, so that the target area to be provided with depressions can be covered with precisely two perforation processes, etc.

Furthermore, a vote of support and perforation device may include a targeted selection of the shape and / or size of the perforation elements and thus the shape and / or size of the recesses in adaptation to a to be achieved carrying capacity of the holder. If the holder is to serve for hanging heavy objects, for example, it is advisable to have deeper and / or larger depressions in the circumference (ie longer and / or larger perforation elements) in order to enhance the effects described above and thus to improve the support of the holder; usually only light objects are picked up by the holder, shallow, small depressions (ie shorter and / or smaller perforation elements) are sufficient.

In one embodiment, the set additionally comprises a portioned, for example airtight, packaged amount of an adhesive which can be applied to the adhesive surface shortly before the holder is pressed against the target surface. In other embodiments, the adhesive is already applied to the adhesive surface of the holder, such as punctiform or as a layer. For example, a film protects the adhesive which is peeled off before being pressed against the target surface. In addition, some embodiments of the kit additionally include a cutting wire for detaching the adhered mount: If the mount is to be detached from the target surface, this cutting wire is grasped at both its ends and placed there where the (top) end of the mount is against the target surface rests, and pulls it behind the bracket down, possibly with reciprocating movements in the manner of a sawing operation. Preferably, the wire is made thin so that it can be moved easily behind the holder; in some embodiments, it has a cutting edge that facilitates separation of the holder and the target surface.

In addition, in one embodiment, to allow for flexible use of a mount for various items, the set includes one or more of the retainers described above. For example, retaining pieces with differently sized or differently shaped further receiving sections are used for this purpose, all of which can be accommodated in a receiving section arranged on the base plate in a plug connection or, with respect to their dimensions, all matching the receiving section arranged on the base plate. Alternatively, the inventive sentence several identical holding pieces are given, such as when the receiving portion can hold several holding pieces, as is the case with curtain rails.

With regard to the adhesive mount as such is again on the already mentioned above WO 2011/00469 A1 the applicant, the content of which is hereby incorporated by reference.
