Description

The invention relates to a rosette arrangement for a door according to the preamble of claim 1.

In the field of building hardware, a distinction is made between handle and key rosettes. While handle rosettes are usually located in the upper lock area, the key rosettes are located in the lower lock area to disguise the keyholes. The determination of the key rosettes on the door usually takes place by means of screws. However, these often remain visible, which can be perceived as aesthetically disturbing.

To counter this, for example, see DE 1 971 389 U1 and EP 0 484 594 A1 so-called clips rosettes. Even with these, the rosette is first attached by means of screws on the door leaf. To cover the screws then a separate cover is placed on the stopper body. This is secured for example by means of locking or spring elements. In this way, the screws are no longer visible, but the rosette has a not inconsiderable thickness. Again, this is often perceived as visually disturbing. In addition, there is a risk that the cover over time again and again detached from the stopper body, whereby the screws are exposed again.

A disadvantage of these solutions is also the time-consuming assembly of the rosettes. Thus, the fastening screws must always be matched to the respective thickness of the door. If they are too short or too long, the rosette can not be mounted. It is therefore usually necessary to stockpile a variety of different screws. The assembly always requires the right tool for tightening the screws. At least five mounting steps are necessary on each side of the door: First, the holes for receiving the screws must be introduced into the door leaf, then the respective stop body must be created, the screws must be threaded through the stopper body in the hole and then screwed. Finally, the cover must be put on. This is generally cumbersome and second-intensive.

The aim of the invention is to avoid these and other disadvantages of the prior art and to provide a rosette for a door, in particular for the area of the keyhole, which is inexpensive and easy to handle by simple means. In particular, a solution is to be created that allows to make the rosette as flat as possible and to assemble without any tools. Required fasteners should be invisible after installation. In addition, the installation should be independent of the door thickness and ensure a permanently firm and correct fit.

Main features of the invention are specified in the characterizing part of claim 1. Embodiments are the subject of claims 2 to 10.

In a rosette arrangement for a door, wherein the rosette arrangement comprises two stop elements, which can be attached to both sides of the door attachable and with at least one fastening device to each other, wherein the fastening device consists of at least a first and at least a second fastening element, the invention provides that the at least one first fastening element is arranged on the back of a stop element and the at least one second fastening element on the back of the other stop element, that the at least one first fastening element in which at least one second fastening element can be fixed, wherein the at least one second fastening element has a receiving element, into which the at least one first fastening element can be inserted, and wherein the receiving element is reversibly deformable by the insertion of the at least one first fastening element such that the at least one first fastening element in the receiving element is non-positively fixed.

The fact that the fastening elements are arranged on the back of the stop elements and thus substantially part of the stop elements, the stop elements can be fixed directly to each other. It is expedient here if the fastening elements are designed such that the first fastening element can be fixed in the second fastening element. For this purpose, the second fastening element, for example, have an axial bore or a sleeve for receiving the first fastening element. The first fastening element may have the shape of a bolt, which is inserted into the sleeve or the axial bore and held there by frictional engagement.

The invention thus offers the great advantage that in the stop elements neither additional, visible from the outside holes for further fasteners nor other cover in any form are necessary. Consequently, the entire rosette arrangement can be made particularly flat and visually appealing.

A particular advantage of the invention is that the receiving element is so reversibly deformable by the insertion of the at least one first fastening element, that the first fastening element in the receiving element is non-positively fixed. In this way, no further fastening and / or guide elements are necessary. The attachment can be done completely without additional tools by the two components are simply pushed together. At the same time, the production of the stop elements is possible without major assembly of a complicated fixing mechanism. For example, the second fastening element can simply consist of a short cam with a thread, which at the back of the Stop element is attached. On the thread then the receiving element can be screwed. It is advantageous if the receiving element consists of a flexible material such as polyoxymethylene (POM). Of course, it is also conceivable to use another correspondingly flexibly deformable plastic material.

When inserting the first fastening element into a receiving element made of such a material, the cross section of the receiving element is deformed in accordance with the shape of the fastening element. Frictional forces act between the surface of the first fastening element and the inner surface of the receiving element. These result from the endeavor of the flexible plastic to return to its original form. Consequently, the frictional forces act in particular at the points at which the first fastening element pushes the receiving element out of its actual shape. By these frictional forces, the first fastening element is held in the receiving element.

For mounting the rosette assembly on the door, it is therefore only necessary to arrange the stop elements on both sides of the door, they move through a previously introduced into the door hole on each other and thereby push the first fastener into the receiving element. Once the receiving element is deformed by the first fastener, the stop elements hold each other firmly. The stop elements are then - overcoming the already acting frictional force - pushed so long to each other until they rest firmly on both sides of the door. It can be seen that it is a further particular advantage of the invention if the insertion of the first fastening element in the receiving element is infinitely effected. In this way, the rosette assembly according to the invention can be mounted on doors with different thicknesses.

In a preferred embodiment of the invention it is provided that the fastening device comprises two first fastening elements and two second fastening elements. This has the advantage that the stop elements can not be rotated against each other, since they are fixed to each other at two points. It is particularly advantageous if each receiving element has a first and a second fastening element, wherein the first and second fastening elements are point or axially symmetrical to the center of the respective stop element. This has the advantage that all stop elements are formed identically, whereby the Number of stocking different components is significantly reduced. If two such identically shaped stop elements are joined together to form a rosette arrangement, they are, as one easily recognizes, so arranged on both sides of the door, that face their backs. If in each case a first and a second fastening element are arranged on each rear side in the symmetrical manner described above, the first fastening element of one abutment element and the second fastening element of the other abutment element and vice versa are in the arrangement of the abutment elements on the door.

It can be seen that a further advantage of the invention lies in the fact that the fastening elements are aligned in an axial direction to the back of the stop elements. This facilitates namely the joining of the stop elements into one another.

Another great advantage of the invention is that the rosette arrangement has a centering device. This ensures that the stop elements can always be mounted in the correct function on the door. It also ensures that the already mounted stop elements can not be moved radially or rotated in the circumferential direction. It is expedient if the centering device comprises at least one securing element which is arranged on the back of one of the two stop elements. Preferably, the securing element engages in the assembled base of the rosette arrangement in a recess of the door. For example, it is conceivable that in the door leaf or in the lock assembly, two through holes are present, the size and distance from each other is such that the mounted on the back of the stop elements fasteners can be inserted straight through the two holes. If the respective stop element applied in this way to the door, it can not be displaced in the radial direction nor rotated in the circumferential direction and is simultaneously held in the axial direction by the opposite stop element on the door. It can be seen that it is particularly favorable if the securing element is formed by a first and / or second fastening element.

It can therefore be seen that the particular advantages of the rosette arrangement according to the invention are that it can be mounted without any tools, that the fastening elements are not visible in the installed state, that they are independent of the Door thickness can be mounted and that it always ensures a permanently firm and correct fit.

In the Fig. 1 generally designated 10 rosette assembly is designed for a (not shown) door, which is usually provided with a mortise, which is embedded in a conventional manner end face in a door leaf. It consists of two stop elements 11, 11 ', which are arranged on both sides of the door leaf and by means of a fastening device 20 to each other can be fixed. The fastening device consists in the present embodiment of two first fastening elements 30 and two second fastening elements 40th

As Fig. 1 further shows, each stop element 11, 11 'on its rear side 13, a first fastening element 30 and a second fastening element 40. These are arranged so that in each case the first fastening element 30 of a stop element 11, 11' and the second fastening element 40 of the other Stop element 11 ', 11 can face, when the backs 13 of the stop elements 11, 11' facing each other. It can be seen that the front side 14 of the stop elements 11, 11 'is formed completely smooth except for an optionally existing recess 12 for a keyhole.

The first fastening element 30 consists in each case of a bolt which protrudes in the axial direction X from the rear side 13 of the stop elements 11, 11 '.

To fix the first fastening element 30 in the receiving element 60, the fastening element 30 is provided at its front end 31 with a bolt thickening 32 (cf. Fig. 2 , Cutout Z out Fig. 1 ). This is essentially a deformation of the cross section of the first fastener 30, for example, by this laterally flat crushed or pressed in a limited section.

The Bolzenaufdickung 32 thus consists of two opposing bulges 33, each projecting beyond the preferably circular or cylindrical periphery 35 of the fastener 30 and two behind the periphery 35 of the fastener 30 receding recesses 34 in the form of flat side surfaces. In the other areas, the first fastening element 30 retains its circular cross-section, in particular at the front end 31 and between the thickening 32 and the projection on the respective stop element 11, 11 '.

It is important that the opposing bulges 33 are dimensioned such that their crest dimension is greater than the preferably circular inner diameter of a recess 61 of the second fastening element 40, in which the first fastening element 30 is inserted for mounting.

The second fastening element 40 consists of a receiving element 60, which is mounted on a mounting cam 50 and also protrudes in the axial direction X of the back 13.

The receiving element 60 consists of a cylindrical sleeve made of a reversibly deformable material, which is formed with a recess 61. In this recess 61, the first fastening element 30 can be introduced during assembly of the rosette assembly 10.

The receiving element 60 is screwed onto the mounting cam 50. For this purpose, the fixing cam 50 as in Fig. 3 recognizable by a foot 52 which is fastened on the rear side 13 of the respective stop element 11, 11 'and a short cam 51 which is formed with a thread. The fastening cam 50 is made of the same material as the stop element 11 or 11 '. It may be attached to the back 13 by gluing, welding or soldering.

Of course, it is also conceivable that the short cam 51 has a smooth or profiled surface on which the receiving element 60 is simply pushed and fixed there by compression, welding, soldering or the like, or that it is made of a different material than the stop element 11, 11 '. is made.

When inserting the first fastening element 30 into the second fastening element 40, the previously circular cross section of the receiving element 60 is deformed into an oval cross-section at the point at which the receiving element 60 encloses the pin boss 32 of the first fastening element 30. In this case, between the surface of the bulge 33 and the inside of the receiving element 60 friction forces that hold the first fastener 30 in the second fastener 40. The frictional forces arise from the fact that on one side the bolt thickening 62 presses against the plastic inner wall of the receiving element 60 and that on the other side the plastic material tends to return to its original shape, in turn pushing against the bolt thickening 62. It can be seen at this point the advantage of the recesses 34. These cause the plastic material of the receiving element 60 is actually only bending deformed and not stretched. The bolt thickening 62 is dimensioned for this purpose such that its circumference has a different shape than the circumference 35 of the remaining first fastening element 30. However, the size of the circumference of the pin boss 62 is equal to or even slightly smaller than the size of the periphery 35 of the remaining first fastener 30.

It can be seen that in this way the assembly of the rosette assembly 10 is particularly fast and easy. In particular, no tools are required for installation. Instead, the abutment members 11, 11 'are simply placed on both sides of the door (not shown) and slid toward one another by a bore disposed in the door, with the first fastener 30 engaging the second fastener 40, respectively. Once the bolt thickening 32 has been inserted into the receiving element 60, the stop elements 11, 11 'hold each other firmly. All you have to do is push them towards each other until they are close to the door. This entire assembly is limited to only two steps, which are carried out quickly and easily by the bolts are threaded into the corresponding holes and then pushed towards each other. Neither additional fasteners are necessary, nor needed for the months any tool, which not only has a favorable effect on the handling of the rosette assembly, but also significantly reduces the manufacturing and assembly costs.

It can be seen that it is further advantageous if the first fastening element 30 can be inserted steplessly into the second fastening element 40. The assembly of In this case, rosette arrangement 10 can then take place on doors with different thickness, without it being necessary to stockpile special components for each door thickness.

In the in Fig. 1 and 3 The fastening device 20 simultaneously forms the centering device 70. The fastening elements 30, 40 arranged symmetrically on the rear side 13 of the respective stop element 11, 11 'can be guided during assembly by corresponding lock openings or door bores. In this way, both a radial movement, ie moving, the stop elements 11, 11 'and a rotation in the circumferential direction U prevented. A rotation of the stop elements 11, 11 'is impossible in this way. It can be seen that the fastening elements 30, 40 simultaneously form the securing elements 71 of the centering device 70 in the present exemplary embodiment.

A simplified principle of the centering device 70 can be seen in Fig. 3 , Here, the illustration of the receiving element 60 has been omitted on one side to illustrate the structure of the second fastening element 40. As in the previous embodiment, each stop member 11, 11 'has a first fastener 30 and a mounting cam 50 for a second fastener 40. The on the one (concealed) mounting cam 50 patch receiving element 60 causes together with the opposite first fastener 30 of the other stop element eleventh the determination of the rosette assembly 10th

Both the fastening cam 50, on which no receiving element 60 is placed, and the fastening element 30, which lies opposite this fastening cam 50 in the illustrated exemplary embodiment, can be regarded as examples of embodiments for securing elements 71 of the centering device 70. Both have in common that they can each engage in a designated hole or recess in the door or in the lock and so prevent rotation of the stop elements 11, 11 'about the axis passing through the telescoping fasteners 30, 40 prevent. It can easily be seen that a simple pin or pin is also conceivable as the securing element 71.

In order to additionally ensure a secure fit of the securing elements 71 in the corresponding holes or recesses of the door or the lock, the securing elements 71 can be adapted to the shape of the recesses.

That's how you look in Fig. 1 in that the receiving element 60 has at its lower end a circular cylindrical collar 63 which merges at a shoulder 62 into the cylindrical jacket 64 of the receiving element. In addition, the collar 63 may correspond to the inside of the recess both in shape and in size on its outside. It is also conceivable that the collar 63 is formed with countersunk grooves, which serve to compensate for tolerances.

The invention is not limited to one of the above-described embodiments, but can be modified in many ways. For example, various attachment methods for the receiving element 60 on the mounting cam 50 or directly on the back 13 of the stop elements 11, 11 'conceivable. The shape and size of the securing elements 71 can also vary.

Instead of a recess 12 for a keyhole can be provided in or on the stop element an axially fixed rotatable olive to use the rosette arrangement, for example, to a bathroom door can.

It can be seen that it is in a rosette assembly 10 for a door, wherein the rosette assembly 10 comprises two stop members 11, 11 'attachable to both sides of the door and in at least one fastening device 20 are fixed to each other, the fastening device 20 at least one of at least first and at least one second fastening element 30, 40 is, is of particular advantage, if the at least one first fastening element 30 on the back 13 of a stop element 11, 11 'and the at least one second fastening element 40 on the back of the other stop element 11, 11 'is arranged, and if the at least one first fastening element 30 in the at least one second fastening element 40 can be fixed, wherein the at least one second fastening element 40 has a receiving element 60, in which the at least one first fastening element 30 is inserted, and wherein the receiving element 60 through there s introducing the at least one first fastening element 30 is reversibly deformable such that the at least one first fastening element 30 in the receiving element 60 is non-positively fixed.

It is also favorable if the insertion of the first fastening element 30 into the receiving element 60 is infinitely variable. As a result, the rosette assembly 10 can be used on almost any door, because different door leaf thicknesses automatically be compensated. The stop elements 11, 11 'are always flat and secured axially on the door leaf, which has a favorable effect on the stability. In addition, the overall appearance of the door is positively influenced.

Moreover, it is expedient if the fastening device 20 comprises two first fastening elements 30 and if the fastening device 20 comprises two second fastening elements 40. In this case, the first and second fastening elements 30, 40 are preferably arranged point-symmetrically or axially symmetrically with respect to the center of the respective stop element 11, 11 '. It is advantageous if the fastening elements 30, 40 are aligned in an axial direction X to the rear side 13 of the stop elements 11, 11 '.

It can further be seen that it is a particular advantage of the invention that the rosette arrangement 10 has a centering device 70. In this case, it is favorable if the centering device 70 comprises at least one securing element 71, that one of the two stop elements 11, 11 'is arranged on the rear side 13.

It is expedient if the securing element 71 engages in the assembled state of the rosette assembly 10 in a recess of the door.

Moreover, it is expedient if the securing element 71 is formed by a first and / or second fastening element 30, 40.

All of the claims, description and drawings resulting features and advantages including design details, spatial arrangements and method steps may be essential to the invention both in itself and in various combinations.
