The fastener has a reinforcement part made of a metallic material having a flat body with openings and side wall elements adjoining it. The side wall elements are mounted between a retaining ring and wall segments of a ring-shaped holder and are designed for fixing the object mount. There is an adhesive reservoir, the bottom of which facing the substrate is only delimited by the flat body. The top of the adhesive reservoir is delimited by a press-on element; via a displacement of the press-on element in the axial direction, adhesive agent is guided out of the adhesive reservoir solely through the openings in the flat body of the reinforcement part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0068] FIG. 1 shows an exemplary embodiment of the fastener arrangement 1 according to the invention. The fastener arrangement 1 is composed of a fastener 2 as well as an object 4 with an object mount 3. In the present case, the object 4 is a hand towel holder. The object 4 can also be formed by another accessory. The body 5 of the object 4 connects to the object mount 3.

[0069] The fastener 2 is fixed to a substrate, which is formed, e.g., by a wall 6, in particular of a bathroom, wherein the wall 6 naturally runs in a vertical plane, contrary to the depiction in FIG. 4. The terms top and bottom are defined with reference to the substrate to which the bottom of the fastener 2 is fixed.

[0070] The object mount 3 can be placed upon the fastener 2. A setscrew 7 is mounted on a side wall of the object mount 3 for fixing to the fastener 2.

[0071] The fastener 2 has an essentially cylindrical outer contour and is, like the object mount 3, designed with rotational symmetry to an axis of rotation running in the axial direction of the object holder 3 or of the fastener 2.

[0072] As shown in FIG. 2, the fastener has, as individual components, a press-on element 8 (individually depicted in FIG. 5), a ring-shaped holder 9 (individually depicted in FIG. 6), a retaining ring 10 (individually depicted in FIG. 4), a reinforcement part 11 (individually depicted in FIG. 5) and an adhesive strip 12 in the form of a double-sided adhesive strip.

[0073] The reinforcement part 11 is composed of steel. The press-on element 8, the retaining ring 10 and the ring-shaped holder 9 are composed of plastic.

[0074] The press-on element 8 has a circular-disk shaped base 8a and a hollow-cylindrical wall 8b, which opens out on the edge of the base 8a and is oriented perpendicular thereto (FIG. 3).

[0075] There is a filling opening 80 in the base 8a, wherein the press-on element 8 a thread 80a in the form of a female thread is present in the wall segment 8b bordering the filling opening 80.

[0076] Latching lips 13 open out on regions situated opposite one another of the upper edge of the wall 8b of the press-on element 8. The two latching lips 13 are identically formed and project outward from the lateral surface of the press-on element 8.

[0077] On the upper edge of its inner side, the circular retaining ring 10 has two identical recesses 14 that are adapted to the shape and size of the latching lips 13 (FIG. 4).

[0078] On its outer lateral surface, the retaining ring 10 has round cavities 15 and wedge-shaped cavities 15a.

[0079] The ring-shaped holder 9 has a base segment 9a and projecting perpendicular from this, two wall segments 9b, which are separated from one another by two identically designed gaps 16 situated opposite one another (FIG. 6).

[0080] The inner contour of the ring-shaped holder 9 is adapted to the outer contour of the retaining ring 10. In particular, on the inner contour of the ring-shaped holder 9 there are protrusions 17 and wedge-shaped protrusions 17a, the contours of which are adapted to the contours of the cavities 15 and wedge-shaped cavities 15a of the retaining ring 10.

[0081] The reinforcement part 11 composed of steel has a circular-disk shaped flat body 11a with a structure of circular openings 18 (FIG. 5). Side wall elements 19 open out on opposite edges of the flat body 11a, the outer sides of said elements forming sloping surfaces inclined toward the flat body 11a.

[0082] FIGS. 7 to 9 show a pre-mounted unit of the fastener 2, in which the retaining ring 10 is fixed to the ring-shaped holder 9 and the reinforcement part 11 is thus positionally fixed between retaining ring 10 and ring-shaped holder 9.

[0083] The retaining ring 10 with its cavities 15, 15a, is latched onto the protrusions 17, 17a that are provided on the inner sides of the wall segments 9b of the ring-shaped holder 9, by which the retaining ring 10 is fixed to the ring-shaped holder 9 so as to be secured against rotation and the reinforcement part 11 is positionally fixed.

[0084] The side wall elements 19 of the reinforcement part 11 are mounted with minimal play in the gaps 16 between the wall segments 9b of the ring-shaped holders 9, and such that their edge regions project outward beyond the ring-shaped holder 9. These projecting edge regions of the reinforcement part 11 form contact surfaces that abut the inner side of the object mount 3 when it is positioned on the fastener 2.

[0085] In the pre-mounted unit of the fastener 2 (FIGS. 7 to 9), the press-on element 8 is in a locked position. In the locked position, the latching lips 13 of the press-on element 8 lie on the upper edge of the retaining ring 10, outside of the recesses 14.

[0086] The base 8a of the press-on element 8 is thus spaced above the flat body 11a of the reinforcement part 11. The intermediate space between the base 8a of the press-on element 8 and the flat body 11a of the reinforcement part forms an adhesive reservoir 20, which is laterally delimited by the retaining ring 10.

[0087] The adhesive reservoir 20 can be filled with adhesive agent. A tube 21 can be used for this purpose, as depicted in FIG. 13. The tube 21 has a threaded head 22. The threaded head 22 is screwed into the thread 80a of the filling opening 80. The adhesive agent is then filled into the adhesive reservoir 20 from the tube 21.

[0088] FIGS. 10 to 12 show the fastener 2 fastened to the wall 6.

[0089] In a first step, the fastener 2 is pre-fixed to the wall 6 in a target position by means of the adhesive strip 12.

[0090] In a second step, the press-on element 8 is shifted out of the locked position into an actuation position, which is depicted in FIGS. 10 and 11.

[0091] To do so, a user rotates the press-on element 8 about an axis of rotation running in the axial direction and presses the press-on element 8 downward in the direction of the flat body 11a of the reinforcement part 11 until the press-on element 8 is seated on the reinforcement part 11 (FIG. 10).

[0092] In this way the adhesive agent is guided out of the adhesive reservoir 20 solely through the openings 18 of the reinforcement part 11, such that the adhesive agent forms an adhesive layer 23 between the flat body 11a of the reinforcement part 11 and the wall 6, which layer 23 extends into the openings 18 of the flat body 11a.

[0093] After the adhesive layer 23 has cured by air contact, the fastener 2 is permanently fixed to the wall 6 by this adhesive layer 23.

[0094] After the fastener 2 has been fixed to the wall 6, the object 4 can be fastened to the fastener 2 by pulling the object mount 3 over the fastener 2.

[0095] The side wall elements 19 of the reinforcement part 11 then abut the inner wall of the object mount 3. The setscrew 7 is then guided against the sloping surface of a side wall element 19, whereby the object mount 3 and thus the object 4 is fixed to the fastener 2 by means of the side wall elements 19.
