Mounting system for cover elements for interior fittings

The invention relates to a mounting system of the type mentioned in the preamble of claim 1.

Typical examples of cover elements that are to be mounted in a detachable manner using such mounting systems are skirting boards for covering the transition between a wall and the floor or cover strips for the transition between a kitchen worktop and a wall against which this worktop abuts. The invention can also be applied in the same way to any other type of cover element, in particular those that are not strip-shaped but have a short longitudinal extension compared to their height.

Cover elements of the type just described are either nailed directly to the wall or the floor or worktop or are mounted using fastening elements that have a small longitudinal extension and are screwed to the wall at regular intervals. These fastening elements have upward-facing, protruding claws or jaws onto which the cover element is placed from above using a groove provided on its rear side by means of a translational movement that is essentially parallel to the wall.

A disadvantage of these known devices is that there is a relatively high probability that an accidental impact, for example with a vacuum cleaner or the like, will exert a force on the cover element in the opposite direction to the direction of the assembly movement, so that the connection between the cover element and the fastening element is inadvertently released. It is also difficult to mount the fastening elements on the wall at such an exact height above the floor that the cover element attached from above rests evenly on the floor. A tight connection between the cover element on the one hand and the floor and/or the wall on the other is not possible.

t ♦♦ * · ·■·

The invention is therefore based on the object of creating a mounting system of the type mentioned at the beginning, which enables the cover element to be attached to the fastening element quickly and easily, but at the same time significantly reduces the risk of unintentional dismantling and at the same time ensures a tight seal to the floor and/or the wall. ^ ₇

To solve this problem, the invention provides the features set out in claim 1.

Because the fastening element is L-shaped, it can be arranged with its two legs parallel to the wall and to the floor or worktop or the like adjoining it, so that it completely covers the joint to be covered, particularly when it is strip-shaped. The L-shape also makes it possible to provide two connection arrangements between the fastening element and the cover element, one of which is arranged in the area of the free end of the vertical L-leg and the other in the area of the free end of the horizontal L-leg. To join these two connection arrangements, the cover element is no longer pushed onto the mounted fastening element by a purely translational movement parallel to the wall, as was previously the case, but is mounted by a turning/tilting movement about its axis running parallel to the joint between the wall and the floor. To make this possible, the two connection arrangements can be designed, for example, as plug-in, clamping and/or locking connections.

It is not necessary that both connections belong to the same category. Rather, all combinations of different connection types are possible that enable the above-mentioned turning/tilting movement to carry out the assembly.

According to the invention, each connecting arrangement comprises two connecting elements, one of which is provided on the fastening element and the other on the rear side of the cover element facing the fastening element. In this way, it is possible to design the cover element in such a way that, in the assembled state, it completely covers the fastening element and the connecting arrangements, so that they are no longer visible after assembly.

Advantageously, at least one of the two L-legs of the fastening element continues in a soft-elastic sealing lip, which is pressed against the floor and/or the wall during assembly. This sealing lip can also be completely covered by the cover element when assembled. It makes it possible, in particular, to mount the horizontal L-leg of the fastening element slightly above the floor or worktop.

because it seals the remaining gap watertight. This also offers the advantage that practically no impact sound is transmitted from the floor to the wall.

These and further advantageous embodiments of the mounting system according to the invention are set out in the subclaims.

The invention is described below using embodiments with reference to the drawing, in which:

Fig. 4a

to 4c show three phases of the assembly process of a cover element on

the fastening element according to Fig. 3.

The fastening element 1 shown in Fig. 1 is essentially L-shaped and comprises two legs 2, 3, one of which extends essentially vertically in the assembled state, while the other extends essentially horizontally.

A continuous mounting hole 4 is provided in the vertically extending leg 2, through which a screw 5 (see Fig. 2a to 2c) extends in the mounted state into a supporting structure formed, for example, by a vertical wall 6. Alternatively or in addition to screw fastening, the fastening element 1 can also be fastened to the wall 6 by gluing and/or nailing.

In the area of the free end of the vertically extending leg 2, a connecting element 7 is provided, which is approximately hook-shaped in the cross section shown and comprises a comparatively rigid web 8 which projects approximately horizontally from the vertical leg 2 and which extends into a hook-shaped

• • * t · · • •

tip 9, the V-shaped free leg 10 of which protrudes from the web 8 and points obliquely downwards.

The tip 9 is designed to be elastic so that the downward-pointing leg 10 can be pressed upwards towards the horizontal web 8 in a resilient manner and exerts a downward-directed force in this position because it attempts to return to the position shown in Fig. 1 due to the elasticity of the arrangement.

In the region of the free end of the horizontally extending leg 3 of the fastening element 1, a further connecting element 12 is provided, which is formed by a substantially rigid web projecting upwards parallel to the vertical leg 2 of the fastening element 1.

The free end of the horizontal leg 3 continues in a soft-elastic lip 14 which is curved downwards against the horizontal axis of the leg 3.

As can be seen in particular from Fig. 2a to 2c, the fastening element 1 is mounted on the wall 6 in such a way that its horizontal leg 3 extends away from the wall 6 just above a base 16. As a result, the lip 14 is pressed upwards and rests resiliently against this base 16 in order to produce a tight connection here.

This design is advantageous in several respects: On the one hand, it almost completely prevents the transmission of impact sound from the floor 16 to the wall 6, or at least greatly reduces it compared to known systems. The cover element 18 can therefore be used as a soundproofing strip. In addition, moisture protection is achieved for the joint covered by the cover element. In particular, floating floors provide dust protection, since dust (e.g. from glass or rock wool) escaping from the expansion material due to the "pumping" of the floor cannot enter the room due to the effect of the sealing lip 14.

As can be seen from Fig. 2a to 2c, the cover element 18 to be fastened to the fastening element 1 comprises two legs 19, 20 which extend at an obtuse angle to one another, one of which extends essentially vertically in the assembled state, while the other extends obliquely downwards from the lower end of the vertical leg 19 to such an extent that it rests with its front surface 24 on the horizontal leg 3 of the fastening element 1 in the assembled state.

In the back of the vertical leg 19 of the cover element 18, a recess 22 is provided which, when the cover element 18 is used as a vertical

to the drawing plane of the figures, which has the shape of a horizontal groove running in the longitudinal direction of the bar.

In the end face 24, with which the obliquely downwardly extending leg 20 of the cover element 18 rests against the horizontal leg 3 of the fastening element 1, a further recess 26 is provided, which in the above-mentioned case is designed as a vertical longitudinal groove.

The connecting element 7 forms together with the recess 22 a first connecting arrangement, while the further connecting element 12 together with the further recess 26 represents a second connecting arrangement.

Fig. 2a to 2c show the assembly process of the cover element 18 on the fastening element 1 mounted on a wall 6 using these two connecting arrangements.

As can be seen from Fig. 2a, the cover element 18 is first placed with the recess 26 provided in the downward-facing end face 24 onto the upwardly projecting, comparatively rigid, web-shaped connecting element 12, wherein the rear side of the vertical leg 19 of the cover element 18 still has a certain distance from the vertical leg 2 of the fastening element 1 and runs at an acute angle to the latter.

After the recess 26 has been placed on the connecting element 12, the cover element is tilted in the direction of the arrow K (Fig. 2b) towards the vertical leg 2 of the fastening element 1, so that the hook-shaped tip 9 of the first connecting element 7 of the fastening element 1 enters the groove-shaped recess 22 on the back of the vertical leg 19 of the cover element 18.

The vertical clearance of the recess 22 is somewhat smaller than the vertical extension of the free leg 10 of the connecting element 7, which extends obliquely downwards, so that when the cover element 18 is pressed completely against the vertical leg 2 of the fastening element 1, as shown in Fig. 2c, this leg 10 is elastically pressed upwards. Since, as mentioned above, it tries to return to its original position, it presses with a corresponding force against the inner wall of the groove-shaped recess 22, so that a clamping connection is made between the fastening element 1 and the cover element 18.

With the help of the two connection arrangements 7, 22 (clamp connection) and 12, 26 (plug connection), the cover element 18 is detachably connected to the fastening element 1 in such a way that it is protected against both vertical and

· 3

is also secured against horizontal displacement (the latter in the direction of the horizontal leg 3 of the fastening element 1). The cover element 18 can only be released from the connection shown by reversing the direction of the rotation/tilting movement indicated by the arrow K. The probability that such a rotation/tilting movement occurs accidentally due to an unintentional impact is significantly lower than an accidental parallel displacement in a horizontal or vertical direction.

The embodiment of a fastening element 1' shown in Fig. 3 has essentially the same shape as the embodiment shown in Fig. 1. In particular, the connecting element 7 provided in the region of the free end of the vertical leg 2 and the lip 14 extending the free end of the horizontal leg 3 are designed in the same way as in the embodiment according to Figs. 1 and 2.

A significant difference between the two embodiments is the design of the connecting element 28 at the free end of the horizontal leg 3 of the fastening element 1' and its complementary connecting element, namely the recess 29 in the end face 24 of the cover element 18" facing the horizontal leg 3 of the fastening element 1' in the assembled state. (Fig. 4a to 4c)

As can be seen from Fig. 3, the free end of the horizontal leg 3 of the fastening element 1' is V-shaped so that one V-leg is formed by the horizontal leg 3, while the other V-leg is directed obliquely upwards and backwards, ie towards the vertical leg 2 of the fastening element V. This upper V-leg can be pressed downwards in an elastically resilient manner and then snaps back into its original position when no more deformation force is exerted.

The recess 29 in the cover element 18', which in the case of a cover strip is also groove-shaped, is considerably flatter than the recess 26 of the cover element 18, but has a considerably greater length in the direction of the front face 24. As can be seen in particular from Fig. 4a to 4c, during assembly the cover element 18' is first placed with its upper recess 22 onto the connecting element 7, wherein it is tilted in such a way that the front face 24 is still in front of the free end of the horizontal leg 3 of the fastening element T. If the cover element 18' is then tilted or pivoted in the direction of the arrow K' about its longitudinal axis which is perpendicular to the plane of the drawing, as shown in Fig. 4b and 4c, the web 30 delimiting the recess 29 slides away over the upwardly pointing V-leg of the connecting element 28 and presses it downwards. In the final assembly position (Fig. 4c), the web 30 has extended beyond the free end of the upwardly projecting V-leg of the connecting element 28, so that this V-leg

can spring back upwards and thereby engages behind the rear edge of the web 30. The connecting elements 28, 29, 30 thus form a locking connection which holds the lower end of the cover element 18'.

For disassembly, the connection arrangement formed by the connecting elements 7 and 22 in the region of the free end of the vertical leg 2 is first released by tilting the cover element 18' in the direction of the arrow K', after which the cover element can be freely lifted upwards in order to release the lower locking connection which is not effective in this direction.

Thus, here too, both to establish and to release the connection between the cover element 18' and the fastening element 1', a rotational/tilting movement is required, the accidental occurrence of which is much less likely than that of a pure parallel displacement.

The sealing lip 14 acts in the same way as described above in the embodiment according to Figs. 1 and 2.

Finally, it should be noted that the two connecting arrangements, each of which is assigned to one of the two legs of the fastening element, can be designed in different ways. The only important thing is that a rotating/tilting movement of the cover element about its axis perpendicular to the plane of the drawing figures is required for their joining or disengagement.

Both the fastening element and the cover element can have a very short extension perpendicular to the plane of the drawing or can be designed as long strips. If the cover element is designed as a strip, a strip-shaped fastening element can be assigned to it. Alternatively, it is also possible to mount a strip-shaped cover element with a large number of short fastening elements perpendicular to the plane of the drawing of the figures.
