Stair component

The invention relates to a stairway element for renovating a stairway step which has a step with a butt edge and an adjusting step, the stairway element comprising a step plate with butt section which at least partially covers the step to be renovated, and a setting plate which in turn in the area of the Butt section is connected to the tread plate and at least partially covers the actuating step.

A corresponding staircase component can be found, for example, in DE 92 14 772 Ul. The staircase component consists of a step plate and a setting plate, which are connected to each other via a profile piece extending along the abutting edge of the step. The outer surfaces of the profile piece as well as those of the tread and positioning plate merge flush into one another.

A spatula adhesive is used to attach the stairway element to the step to be renovated, which also fills the space between the shelf and the step. However, a corresponding stairway element is unsuitable for the renovation of stairs that have a protruding butt edge. It is also not ensured that the profile piece connecting the tread plate to the positioning plate does not break out when strong force is applied. To prevent this, according to DE 87 07 245 Ul a kit for renovating stairs is provided, which comprises a Z-profile to be applied to the step to be renovated, which is screwed to the step on the one hand and on the other hand a step plate and a step leading edge strip can be fastened, which are additionally positively supported on a projecting web of the Z-profile.

From FR 2 671 822 AI a multi-stage kit for the renovation of a stair step is known, which comprises a stair nosing, on the one hand a starting plate lying flat against an adjusting step and on the other hand a step plate. To fix the position of the stair nosing, it is embedded in mortar at least in some areas.

Other proposals for covering stairs to be renovated also provide for multi-part components that are assembled on site. For example, in DE 35 42 952 AI proposed that wooden ledges projecting above their original height and a U-shaped metal rail encompassing the abutting edge be fastened on the stepped step in order to subsequently fix a wooden support with the bump ledge using assembly foam.

In order to renovate a step according to DE 35 17 673 C2, an L-shaped profile covering the step and the butt edge is provided, the step leg of which has an insert made of chipboard on its underside, which has a lower specific weight than plastic.

A prefabricated covering of a stair step according to EP 0 061 707 A2 provides a structure comprising at least three layers, which are glued together in the area of the tread edge over their full contact surfaces.

DE 85 14 515 U1 describes a covering for the renovation of exited stair treads, which consists of two legs which are joined together in one piece and are made of tread and abrasion-resistant plastic. According to EP 0 312 488 B1, a profile having a W shape is screwed to the adjustment step of a step to be renovated in order to be able to perform the required supporting function of a step plate to be attached to the step. In order to prevent the old step from creaking, it is raised by a preselected amount by means of a new riser or adjusting step. The new setting stage is clamped between the profile and a new tread plate running below it.

DE 80 26 427 Ul shows a stair step for the renovation of old buildings, the old setting step being covered by a cover which starts from a gap running between a projecting edge of a new stair step and the step edge of the old stair step and extends as far as previous new step extends.

A large number of other previously known proposals for the renovation of stairs to be renovated also provide for multi-part components or those that only partially cover the stairs themselves. For example, reference is made to DE 86 04 260 Ul, DE 80 26 427 Ul, DE 85 04 095 Ul or DE 38 03 077 C2.

The present invention is based on the problem of developing a staircase component of the type mentioned at the outset in such a way that renovation of a stair step is possible with structurally simple measures, at the same time providing an optically appealing exterior. Furthermore, if the tread plate and tread edge area are composite elements, the latter should not be damaged even under heavy load without a profile element serving as a support necessarily running between the tread plate and the stair step or the profiled element being connected to the stair step got to. The problem is solved according to the invention essentially in that the adjusting plate covering the adjusting step supports the tread plate. The setting plate is preferably offset from the end face of the tread plate or that of the butt section.

In order to renovate a stair step according to the invention, only the tread plate having the joint section and the positioning plate are required. Even if the butt section is assembled with the tread plate and the former protrudes beyond the butt edge of the tread to be renovated, breaking off the butt section under heavy loads is impossible, since it is supported by the adjusting plate.

In order to ensure an appealing exterior and to be able to renovate stairs with projecting abutting edges, a proposal of the invention provides that the positioning plate consists of parallel or substantially parallel and offset outer sections and a central section that continuously merges into them.

In order to align the setting plate to the butt section in a simple manner and to fix it, it is provided that the setting plate can be fixed in position in a groove running on the underside in the butt section, the outer (upper) section of the setting plate which can be introduced into the groove of the butt section being shorter than the section running along the abutting surface.

In order to support the butt section or the tread plate to the required extent, the latter is supported along its lower edge via fixing elements and / or, in particular, a curable foam. These measures ensure that the setting plate always supports the butt section to the extent necessary, even when large forces should be introduced into the setting plate via the butt section. In addition, the setting plate can be connected at least in some areas to the setting step, in particular by gluing. According to a further proposal of the invention, it is provided that the abutting edge is covered at least in regions by a support element such as an angle profile or profile strip. In particular, the support element is an angular profile, one leg of which extends along the end face of the abutting edge and the other leg along the tread of the stairs to be renovated. However, the support element does not necessarily perform the support function required in known staircase renovation systems, which, according to the invention, is carried out by the setting plate.

For reasons of stability, it can be provided that the central section of the positioning plate rests on the abutting edge or on the supporting element covering it.

Furthermore, it can be provided that the tread edge region extends along the end face of the abutting edge and, in the presence of a support element, is supported at least on a projection extending from it. The projection can preferably be a web running in the longitudinal direction of the support element.

Irrespective of this, the tread edge area lies at least in areas flat against the end face of the abutting edge or the support element, preferably made of aluminum, such as an angle.

The tread edge area or butt section and tread plate can be formed in one piece. This can be a cast or extruded element.

However, the tread edge area and tread plate preferably consist of separately manufactured elements, the tread edge area being real wood, polyurethane or aluminum. The tread plate, on the other hand, can consist of plastic, metal, which is at least externally covered with a film, or of solid wood, veneered plywood or veneered blockboard. In order to enable a secure connection between the tread edge area and the tread plate, these can be mortised in a known manner or in particular connected via a tongue and groove connection. In addition, the elements in the joint area are glued. The latter preferably runs above the step.

In a proprietary design, it is provided that the tread edge area is formed by a profile element which is detachable or is formed as a unit with the tread plate, the profile element preferably being a hollow-chamber profile with a U-shaped section, between its parallel section, via a first transverse leg connected longitudinal legs the tread plate can be fixed with its front end region that a second transverse leg extending from one of the longitudinal legs extends along the end face of the abutting edge of the stairs, that the first transverse leg has a section running parallel to the second transverse leg and that between the section of the first cross leg and the second cross leg, the setting plate can be fixed. The second cross leg and - or the section running along the tread of the staircase to be renovated can be connected with it by e.g. Screws connected.

In particular, it is proposed that the section of the first cross leg and the second cross leg are connected via a web running parallel to the longitudinal legs, against which the positioning plate rests or engages, or that a groove accommodating the positioning plate on the edge runs in the web .

Another solution provides that the profile element forming the tread edge region comprises a cuboid base section having the groove on the underside, from which a web forming a stop for the tread plate extends, the front side of which is flush with that of the base section and the top side is aligned with that of the tread plate. Such a profile element is preferably made of real wood or veneer.

There is also the possibility that the profile element forming the tread edge region comprises a parallelepiped-shaped base section on the underside, of which a leg extending parallel to the tread plate surface and extending in the direction of the tread plate extends, the upper side of which is flush with that of the tread plate, the leg extending in the direction of the tread plate with its free edge region being able to protrude beyond the base section on the stairs side. A corresponding profile element can consist of polyurethane.

The setting plate itself can be supported on a step plate of another stairway element. However, the setting plate is preferably supported on a tread surface of a preceding step clad with a staircase component. As a result, the lower edge of the positioning plate is covered, so that supporting elements such as wedges or the hardening foam by which the positioning plate is fixed in position are covered.

Further details, advantages and features of the invention result not only from the claims, the features to be extracted from them - by themselves and / or in combination - but also from the following description of preferred exemplary embodiments which can be found in the drawing.

Show it:

1 shows a section through a renovated step,

Fig. 2 is a schematic diagram of a renovated step on average and

3 to 5 embodiments of tread edge profile elements.

In Fig. 1 a step (10) of a staircase to be renovated is shown on average. The step (10) is composed in a known manner of a step (12) with a step surface (14) and a riser (16) with a butt surface (18). Between the step (14) and the riser (16) of the stairs (10) extends a projection (20) to be called a butt edge with approximately parallel to the butt surface (18) extending end face (22).

If the stairs are e.g. emerged step (12) to be renewed without having to remove the step (10) itself, according to the invention a staircase element (24) is arranged on the step (10) to be renovated. The staircase component consists of a tread plate (26) with a front tread edge area (28) and an adjusting plate (30).

An angle profile (32) can also be arranged in the region of the abutting edge (20), e.g. made of aluminum. The angle profile (32) extends with its one leg (34) along the step (14) and with its other leg (36) running at right angles thereto along the end face (22) of the abutting edge (20).

In the exemplary embodiment, the tread plate (26) is an element which is separate from the tread edge region (28) and can be connected to one another via a tongue and groove connection (38) or also by means of a mortise and tenon. Of course, there is also the possibility that the tread plate (26) and the tread edge area (28) are one part. This can e.g. be a plastic part or an extruded profile.

Particular embodiments of the profile elements forming the tread edge region are shown in FIGS. 3 to 5.

If the butt section or tread edge area (28) and tread plate (26) are separate elements, the butt line (40) according to FIG. 1 runs above the tread (12) or the butt edge (20) and when the angular profile (32) is present. above its horizontal leg (34).

The tread edge region (28) also extends in regions along the end face (22) of the abutting edge (20), that is to say when the angular profile is present. (32) along the leg (36) and lies flat against this. The edge (42) facing the end face (22) or the leg (36) of the angular profile (32) can a web-like projection (44) is supported, which starts from the existing leg (36) of the angle profile (32).

If the latter is not present, support elements can optionally be introduced into the end face (22) of the abutting edge (20).

According to the invention, the tread edge region (28) is supported by the positioning plate (30). In order to fix the positioning plate (30) on the underside (46) of the tread edge area (28) in a simple manner, a longitudinal groove (48) is provided, which is chamfered on the outside, i.e. in the front area (50), so that when the tread plate (26 ) to allow easy insertion of the positioning plate (30).

So that the adjusting plate (30) can support the tread plate (26) or the tread edge area (28), the former is supported along its lower edge (52) against a fastening surface (54) which, in the exemplary embodiment, is the tread surface of a preceding surface level (56).

The support is preferably provided by a curable foam (58), through which a fixation takes place at the same time. Other support or fastening elements such as wedges, screws or the like are also possible.

The setting plate (30) is composed of two outer sections (60) and (62) and a middle section (64) which continuously merges into the former. The outer sections (60) and (62) run parallel and offset from one another.

Furthermore, the outer section (62) running along the abutting surface (18) can be connected to the former as if glued. It can also be seen that the section (60) opening into the groove (48) is shorter than the section (62) running along the abutting surface (18). The middle section (64) preferably runs in a straight line and preferably describes an angle between 30 ° and 60 ° to the adjacent sections (60) and (62) of the setting plate (30).

For further stabilization, the middle section (30) can abut the abutting edge (20) or the angular profile (32) covering it at least in some areas, specifically on the longitudinal edge (66) of the vertically or essentially vertically extending leg (36).

As further illustrated in FIG. 1, the joint area between the setting plate (30) and the support surface (34) is covered by a step plate (68) covering the step surface (54) of the preceding step (56).

In order to assemble the staircase component (24) according to the invention, the butt edge (20) of the original step (10) is first shortened to the extent necessary, and then the angle profile (32) is preferably fastened by screws (70). However, this is not absolutely necessary. The tread plate (26) with tread edge region (20) is then fixed on the tread surface (14) of the tread (12), preferably by means of curable foam. The setting plate (30) is then cut to length and introduced into the groove (48) running along the underside (46) of the tread edge region (28) and is preferably fixed in place by means of the curable foam (58).

It should also be mentioned that an anti-slip element can be applied or embedded on the top of the tread plate (26). This can be a hard rubber strip of known type. If the tread plate (26) or the tread edge area (28) is a cast or extruded element, a structuring can be specified in the area of the tread edge area (28), which likewise achieves an anti-slip effect.

If the tread plate (26) and the tread edge area (28) are separate elements, the latter can consist, for example, of fine wood or polyurethane or a hollow chamber profile, for example be made of aluminum. The tread plate (26) can be made of veneered plywood or solid wood or blockboard, of metal or plastic. Other materials are of course also possible.

FIG. 2 shows a schematic representation of the renovated staircase (10) corresponding to FIG. 1, which is covered on the step side by the step plate (26) and on the step side by the adjusting plate (30).

The tread plate (26) merges into the tread edge region (28) which, according to the exemplary embodiments in FIGS. 2 and 3, is a profile element (72) and consists of real wood. The profile element (72) is composed of a cuboid base section (74) and a web (76) serving as a stop for the support plate (26). The front of the base section (74) is aligned with that of the web (76), the top of which in turn is aligned with that of the tread plate (26).

On the underside, the base section (74) has the groove (48) which receives the adjusting plate (30).

In Fig. 4, a profile element (78) made of polyurethane is shown, which can be cast onto a tread plate (26) or connected to it in some other way.

The profile element (78) also comprises a base section (80) corresponding to the base element (74) of the profile element (72), of which a leg (84) which has a receiving groove (82) running parallel to the tread surface and extends in the direction of the tread plate (26) ) goes out, the top of which is flush with the tread plate (26) in the area of the tread edge. Furthermore, the leg (84) can be structured on the outside, that is to say in the front region of the tread, in order to bring about an anti-slip effect.

5 shows a profile element (86) in the form of a hollow chamber profile, preferably in the form of an extruded profile made of aluminum. The hollow chamber profile has a section which has a U-shape and between which section is parallel to one another. other extending longitudinal leg (90), (92) connected via a first transverse leg (88), the tread plate (26) can be fixed with its front end region. From the underside longitudinal leg (90), which has a greater transverse extension than the longitudinal leg (92), a second transverse leg (94) extends along the end face (22) of the abutting edge (20), possibly in its free edge area can be connected to the abutting edge (20) by means of screwing means, for example.

The first transverse leg (88) is extended beyond the longitudinal leg (90) (section (96)), the transverse extent of the section (96) being less than that of the parallel leg (94), by the latter mentioned at the abutting edge (20) to be able to attach.

The section (96) of the first cross leg (88) and the second cross leg (94) are connected via a web (98), so that this is connected to the section (96), a section of the cross leg (94) and a section of the Longitudinal leg (90) delimits a chamber (100).

The groove (48) is then formed in the web (98) in order to fix the setting plate (30).

The surface of the longitudinal leg (92), like the leg (84) of the profile element (78), can be profiled according to FIG. 4-. The upper side of the leg (62) is also flush with the free surface of the tread plate (26), as shown in FIG. 5.

It should also be mentioned that when the tread edge area or the front section of the tread plate (26) abuts the angle profile (32), the projection (44) projecting from its vertically extending leg (36) on which the underside of the tread edge region (28), which is preferably designed as a profile element, has a depth such that the front free end face (102) of the projection or web (44) merges into the longitudinal wall (104) of the groove (48). As a result, the positioning plate (30) is supported when it is introduced into the groove (48).
