EP3461966B1 - Step or staircase arrangement for sloping areas with different inclinations - Google Patents

Description

The invention relates to a step or step arrangement for free laying on a slope, according to the preambles of claims 1, 3 and 5 and a method for free laying such a step or step arrangement according to claims 2, 4 and 6. Furthermore, the invention also relates a step or staircase system, in particular a floor-based staircase, consisting of several such step or stair step arrangements according to claim 16.

Walking, standing and working on steep slopes, especially on steep inclines, is difficult and dangerous. This applies all the more when loads have to be carried or tools have to be handled when the machine is at a standstill, e.g. for working on soil and plants or during construction work. In doing so, a significant part of the force applied must be used to maintain body balance. Nevertheless, falls or slides down the slope are often unavoidable. These difficulties can increase to such an extent on slippery or wet slope surfaces that standing, walking or working on the slope surface can only be accomplished with aids.

To solve these problems, the EP 0 753 645 A1 a mobile, freely routable single step in the form of a one-piece, angled element, one leg of which forms a tread plate, and which is provided at least at one end with means for adhering or clawing to the site. The means for fixed claws on the site are formed by claws protruding from a free edge of the leg. However, the angle of the tread plate in relation to the slope is determined by the geometry of the legs. In the case of large slopes, it may happen that the tread surface is also undesirably inclined, deviating from an ideal horizontal position.

A generic step or step arrangement is in DE 93 16 169 U1 described. There, support feet can be telescopically extended to a desired length in order to bring the tread part into a horizontal position on a slope. The length of the support feet set in each case is fixed by inserting pins which can pass through aligned holes in the outer tubes and inner tubes. The ends of the inner tubes are chamfered to facilitate penetration of the support feet into the floor. The depth of penetration is limited by a cross bar that connects the two inner tubes and is fixed on both sides. Two diagonal telescopic tubes connect the support feet to a rear edge section of the frame. Overall, the telescopic guides and the additional crossbar create a complex construction, which is also sensitive to dirt, because dirt can penetrate between the telescopic guides, which can be pushed into one another, and thus prevent or impair a relative movement of the pipes.

US 2004/255406 A1 discloses a step or stair step arrangement in which first and second limiting elements are provided in openings on the front support feet and are pivotally attached to the step plate. Furthermore, a third limiting element is fastened by pins between the front support feet. However, since no length compensation is provided for the first and second delimitation elements, the construction squeezes when the first and second delimitation elements are fastened in openings arranged at a different level to adapt to a changed slope. In addition, the attachment of the third delimitation element in the openings of the front support feet is time-consuming if the tread or step arrangement is to be adapted to a changed slope slope while maintaining a horizontal orientation of the tread surface.

In contrast, the invention is based on the object of a step or step arrangement for free laying on a slope of the entrance to further develop the type mentioned in such a way that it can be adapted to various slopes with simple and inexpensive means. Furthermore, a method for freely laying such a step or stair step arrangement and a step or stair step system, in particular a floor-based staircase, which consists of several such step or step arrangement.

This object is achieved by the features of the independent claims 1, 2, 3, 4, 5, 6 and 16.

According to the invention, a particularly effective limitation of the penetration of the free ends of the foot parts into the slope surface is achieved in that the at least one rod-shaped delimitation element protrudes laterally out of the passage openings and protrudes laterally beyond the foot parts in question.

The specific first through opening and the specific second through opening can in particular be aligned through openings, so that the limiting element is then aligned horizontally. Alternatively, certain first through opening and the certain second through opening can be through openings which are not aligned with one another, in which case the delimiting element is oriented obliquely with respect to the horizontal. In particular, the through openings can also be designed in the manner of an elongated hole in order to enable such an oblique alignment of the limiting element.

The specific third through opening and the specific fourth through opening can in particular be aligned through openings, so that the limiting element is then aligned horizontally. Alternatively, certain third through opening and the certain fourth through opening may not be aligned through openings, in which case the delimiting element is oriented obliquely with respect to the horizontal.

In the second aspect of the invention, the principle of the first aspect implemented in the front foot parts is therefore applied to the rear foot parts.

The process steps a) to c) are specified in the order in which they occur in succession. The chronological order of steps a) and b) can also be reversed.

According to a third aspect, the invention is based on a step arrangement for free laying on a slope surface, comprising at least one step or stair step body with a step surface intended for entry by at least one foot of a person, and with at least two in the use position at the front, from the step surface foot parts protruding downwards, which have a first vertical extent measured from the tread surface, the free ends of the front foot parts being provided for at least partial penetration into the slope surface, at least two rear in the use position, protruding downwards from the tread surface and transversely from one another spaced foot portions, each of which has a second vertical extension measured from the tread surface, the free ends of at least the rear foot portions being provided for at least partial penetration into the slope surface, the first vertical extension being greater than the second kale extension is.

According to the invention, the third aspect provides that at least on one side of the tread or stair step body, on a rear foot part of the rear foot parts arranged on this one side, a plurality of fifth passage openings arranged on different (vertical) levels and on one side on this side front foot part of the front foot parts, a plurality of sixth through openings arranged at different (vertical) levels is formed, and that at least one rod-shaped limiting element is designed for optional loose insertion in a certain fifth through opening of the plurality of through openings and into a certain sixth through opening of the plurality of sixth through openings is provided such that penetration of the free end of the at least one front foot part and the free end of the through the limiting element inserted into the specific fifth through opening and the certain sixth through opening at least one rear foot part in the slope area is limited to a (vertical) level which corresponds to the (vertical) level of the limiting element.

The specific fifth through opening and the specific sixth through opening can in particular be aligned through openings, so that the limiting element is then aligned horizontally. Alternatively, certain fifth through opening and the certain sixth through opening can be non-aligned through openings, in which case the delimiting element is oriented obliquely with respect to the horizontal.

In the third aspect of the invention, the principle of the first aspect, which is realized in the front foot parts, is transferred to a front and a rear foot part on at least one side of the tread or stair step body.

A method for freely laying a step arrangement according to the third aspect on a slope is then characterized by at least the following method steps:

1. a) loose insertion of the rod-shaped limiting element into the specific fifth through opening and into the specific sixth through opening depending on the inclination of the slope surface,
2. b) positioning the step or stair step body on the slope surface such that the at least two front foot parts face down the slope and the at least two rear foot parts face up the slope,
3. c) pressing in the free end of at least the front foot part arranged on one side of the step or stair step body and the free end End of at least the rear foot part arranged on one side of the step or stair step body into the slope surface until the limiting element inserted into the specific fifth through opening and into the specific sixth through opening rests on the slope surface and thereby further penetration of the free end of at least one on the one Side of the tread or stair step body arranged front foot part and the free end of at least the rear foot part arranged on one side of the tread or stair step body in the slope area is prevented.

The process steps a) to c) are specified in the order in which they occur in succession. The chronological order of steps a) and b) can also be reversed.

As a result, the limiting element inserted into the specific through openings prevents the free ends of the relevant foot parts of the tread or stairway body from being loaded, e.g. penetrate deeper into the (soft) slope surface by means of the appearance of a person than is specified by the respective vertical level of the boundary element. Depending on the inclination of the slope, the limiting element can be inserted into certain through openings in such a way that when the step or stair arrangement is positioned on the slope, the step is (almost) horizontally aligned and therefore a person's foot slips or slides off the Tread is prevented.

"Loose insertion" means that the delimiting element in the unassembled state of the step or stair arrangement is received loosely or with play in the through openings, so that the delimiting element can be easily inserted or inserted into the through openings, while in the assembled state or in the use position, the tread - or stair step arrangement on the slope, the limiting element is held in the through openings by frictional forces, which use in particular the weight forces of the step or stair step arrangement People and / or caused by the longitudinal forces due to the penetration of the free end of the foot parts in the slope area. In particular, the outer diameter or outer dimensions of the delimiting elements are smaller than the inner diameter or inner dimensions of the through openings.

The invention can therefore be used on slopes in which the free ends of at least the foot parts can penetrate a little when the tread is loaded in order to fix the tread or stairway body in the slope. For this purpose, the cross sections of the ends of the foot parts can be designed, for example, with a relatively small cross section.

The invention can be implemented with simple means, as only the relevant foot parts are to be provided with through-openings and at least one rod-shaped limiting element is to be provided.

In particular, the through openings are arranged equidistantly on a foot part.

Advantageous further developments and improvements of the invention specified in the independent claims are possible through the measures listed in the subclaims.

According to a further development, the at least one rod-shaped delimitation element and the through openings can each have a circular cross section. Alternatively, the rod-shaped delimitation element can have a circular cross section and the through openings can have an elongated hole cross section. However, any cross section of the rod-shaped delimitation element and the through openings is conceivable, in particular also a square or rectangular cross section, as long as the at least one

Limiting element with play or loose can be accommodated in the through openings.

A particularly inexpensive step arrangement results if the rod-shaped limiting element is formed by a rod of reinforced concrete reinforcement. Such poles are widely available commercially and therefore inexpensive.

The step or stair step body is preferably made of sheet steel or aluminum. An execution as an injection molding from plastic is also conceivable.

The surface of the step surface provided for stepping on is preferably provided with a non-slip pad. Such a non-slip pad can in particular consist of a glued-on film with non-slip properties. Alternatively or additionally, the tread surface can also be designed as a checker plate. As an alternative or in addition, the tread surface can also have through-bores with serrated edges, the tines projecting away from the tread surface.

A particularly cost-effective production of the step or stair step arrangement also results if the step or stair step body contains a one-piece sheet steel part or is formed by such a one-piece sheet steel part in which the at least two front foot pieces and the at least one rear foot piece are bent from the tread surface .

A high degree of rigidity of the tread or stair tread body results if the at least one rear foot part and the front foot parts preferably each have an L-shaped cross section.

An even higher rigidity of the tread or stair step body can be achieved if, in the position of use, a web part is bent on the side of the tread or stair step body, each of which collides with a front foot part and with a rear foot part in a miter. Then a front foot part and a rear foot part can be supported on a lateral web part via the miter when the tread surface is loaded. In addition, the web part can be riveted to the rear foot part and / or to the front foot part in the miter.

The tread surface preferably has a planar extent such that only one foot of a person can appear there. Alternatively, the tread surface can also have a greater width when viewed in the transverse direction, so that, for example, a person with both feet can also step onto the tread surface at the same time.

For optical reasons, a tread plate cassette can be provided in the area of the tread surface for inserting a tread plate, the tread plate in the inserted position being arranged above and parallel to the tread surface in the position of use. The tread plate cassette is preferably connected to the tread or stair step body, in particular to the tread surface, for example by screwing.

The tread plate cassette can have at least two and at most three profiles with a U-shaped cross section and a base, such a profile being arranged on one edge of the four edges of the base and a further edge without fixing means for fixing the tread plate in the tread plate cassette.

In this case, the fixing means can have at least one bendable tab which is arranged on the further edge of the bottom of the tread plate cassette or on the edge of the tread surface such that in a first position the at least a tab allows the tread plate to be inserted into the tread plate cassette and the tread plate is fixed within the tread plate cassette in a second position of the at least one tab bent relative to the first position.

The tread plate can be made of wood, (artificial or natural) stone or plastic, or a mix of materials, depending on the visual requirements.

1. a) in bestimmte Durchgangsöffnungen der vorderen Fußteile und/oder in bestimmte Durchgangsöffnungen der hinteren Fußteile (jeweils) ein Begrenzungselement eingesetzt ist, und/oder dass
2. b) auf der einen Seite des Tritt- oder Treppenstufenkörpers in eine bestimmte Durchgangsöffnung des einen vorderen Fußteils und in eine bestimmte Durchgangsöffnung des einen hinteren Fußteils und/oder dass auf der anderen Seite des Tritt- oder Treppenstufenkörpers in eine bestimmte Durchgangsöffnung des anderen vorderen Fußteils und in eine bestimmte Durchgangsöffnung des anderen hinteren Fußteils (jeweils) ein Begrenzungselement eingesetzt ist.

The invention also relates to any combination of the first aspect, the second aspect and the third aspect, ie that

1. a) a limiting element is inserted into certain through openings of the front foot parts and / or into certain through openings of the rear foot parts, and / or that
2. b) on one side of the tread or stair step body into a certain through opening of the one front foot part and into a certain through opening of the one rear foot part and / or that on the other side of the tread or stair step body into a certain through opening of the other front foot part and a limiting element is inserted (in each case) into a certain through opening of the other rear foot part.

The invention also relates to a step or stair system, in particular a floor-based staircase, consisting of a plurality of step or stair step arrangements described above.

In this case, connecting means can be provided, by means of which a plurality of step or stair step arrangements can be connected to one another.

The connecting means can have at least one connecting profile, of which, viewed in the position of use, at least one first engaging element on a first side and one facing away from the first side second side protrudes at least a second engagement element, wherein the first engagement element engages in a through opening of a first step or step arrangement and the second engagement element engages in a through opening of a second step or step arrangement different from the first step or step arrangement, whereby the first step or stair step arrangement and the second step or stair step arrangement are connected to one another in particular essentially without a viewing gap.

In particular, the first engagement element and / or the second engagement element can also be hook-shaped.

In particular, if the step surface has a planar extent such that only one foot of a person can appear there, the multiple step or stair step arrangements can then, for example, be arranged laterally and also offset with respect to the vertical level on the slope surface in such a way that their order of the step sequence corresponds to a person climbing the slope.

Alternatively, especially if the tread has a larger width in the manner of a stair tread seen in the transverse direction so that a person can step onto the tread with both feet, the multiple tread arrangements can be arranged in a row one behind the other on the slope surface so that they are in alignment with one another stand.

Description of the embodiments

In 1 to 6 Illustrations of a preferred embodiment of a step or stair step arrangement 2 with a step or stair step body 1 for free laying on an inclined slope surface 4 are shown. The slope surface 4 takes, for example, a first slope angle α with respect to a horizontal surface and consists here, for example, of relatively soft soil, so that narrow bodies can easily penetrate the slope surface 4 under pressure.

The tread or stair step body 1 has a tread 6 provided for entering by, for example, only one foot of a person, as well as here, for example, two front foot parts 8a, 8b, which protrude downward from the tread 6 and are spaced apart in the transverse direction, which measure each have a first vertical extension h1 from the tread surface 6 ( Fig. 3 ).

Furthermore, for example, there are two rear foot parts 10a, 10b in the use position, which also protrude downward from the tread surface 6, which, measured from the tread surface 6, have a second vertical extension h2, the first vertical extension h1 being greater than the second vertical extension h2 ( Fig. 3 ).

In the position of use of Fig. 1 , ie if the step or stair step arrangement 2 is attached to or in the slope surface 4, then the front foot parts 8a, 8b form foot parts facing downhill and the rear foot parts 10a, 10b face upwards.

The free ends 12 of the two front foot parts 8a, 8b and the two rear foot parts 10a, 10b are each provided for at least partially penetrating into the slope surface 4 when the tread surface 6 is loaded. Based on the in Fig. 1 shown situation, the tread or stair step body 1 is still unloaded, so that the free ends 12 of the foot parts 8a, 8b or 10a, 10b are still only on the slope surface 4 but have not yet penetrated into it.

In this case, in a first front foot part 8a of the front foot parts 8a, 8b there are a plurality of first through openings 14a1 to 14a6, each with a different level position, and in a second front foot part 8b of the front foot parts 8a, 8b second, for example each with the first through openings 14a1 to 14a6 in the transverse direction seen through aligned through opening 14b1 to 14b6 each formed, for example, equidistant.

The first through openings 14a1 to 14a6 and the second through openings 14b1 to 14b6 differ in each case by a different vertical level on the front foot parts 8a, 8b.

How in particular Fig. 1A , Figure 1B , Figure 1C , Fig. 5 , Fig. 6 and Fig. 7 show is a rod-shaped limiting element 24 for optional lateral and loose insertion into a specific first through opening 14a1, 14a2, 14a3, 14a4, 14a5 or 14a6 and into a specific second through opening 14b1, 14b2, 14b3, 14b4, 14b5 or 14b6, so that the free ends 12 penetrate through the limiting element 24 of the front foot parts 8a, 8b in the slope surface 4 is limited to a vertical level which corresponds to the vertical level of the limiting element 24 used. In the present case, a slope area with a relatively large slope α according to Fig. 1A , Figure 1C , Fig. 5 and Fig. 6 the limiting element 24 is inserted, for example, through the second through openings 14a2 and 14b2, seen from below, for example in alignment with one another, the ends of the limiting element 24 projecting a little laterally out of the through openings 14a2, 14b2, for example. The proportion of the free ends 12 of the front foot parts 8a, 8b which protrude into the slope surface 4 or are inserted therein is relatively small.

Consequently, the limiting element 24 inserted transversely into the through openings 14a2, 14b2, for example, prevents the free ends 12 of the front foot parts 8a, 8b of the tread or stair step body from being subjected to a load, for example by means of a person stepping deeper into the (loose or soft) The slope surface 4 penetrate than is predetermined by the respective vertical level of the limiting element 24. Thus, depending on the respective inclination of the slope surface 4, the limiting element 24 can be used in certain through openings 14a1, 14a2, 14a3, 14a4, 14a5 or 14a6 or 14b1, 14b2, 14b3, 14b4, 14b5 or 14b6 in such a way that the the step surface 2 positioned step surface 2, the step surface 6 is (almost) aligned horizontally and therefore slipping or sliding of a person's foot is prevented when they put their foot on the step surface 6.

Figure 1B shows a situation in which the limiting element 24, for example, is not as in FIG Fig. 1A is inserted into through-openings 14a2 and 14b2 which are horizontally aligned with one another, but into through-openings 14a4 and 14b2 which are not exactly aligned with one another. As a result, the limiting element is then in an angular or oblique position with respect to the horizontal, which is not a result of an adaptation to the shape of the slope surface 4.

Figure 1C shows a situation in which the limiting element 24, for example, in the first front foot part 8a and the second front foot part 8b as in FIG Fig. 1A is inserted into first and second through openings 14a2, 14b2, each with the same level position. Furthermore, the two rear foot parts 10a and 10b each have, for example, two second through openings 16a1, 16a2 or 16b1, 16b2, each with a different level, of which a pair 16a1, 16b1 or 16a2, 16b2 are each aligned horizontally with one another. In the present example, a further limiting element 24a is then inserted, for example, through the lowest through openings 16a1 and 16b1. As a result, the delimiting elements 24, 24a are then in a respective horizontal position.

Fig. 7 shows, for example, the step or stair step arrangement 2 as it is attached to or in a slope surface 4 which, with respect to a horizontal surface, has a second slope angle β which is smaller than the first slope angle α. In this case, the limiting element 24 is inserted, for example, into the second pair of through openings 14a5 and 14b5 in the two front foot parts 8a, 8b when viewed from above. Then the proportion of the free ends 12 of the front foot parts 8a, 8b, which protrude into the slope surface 4 or are inserted therein, is relatively large. Depending on the slope angle or slope inclination, certain through openings that are in alignment here, for example, are therefore used for loose insertion of the limiting element 24 is selected so that when the free ends 12 penetrate the slope surface 4 under load, this penetration is limited by the limiting element 24 in such a way that the tread surface 6 is oriented approximately horizontally in order to ensure a safe step.

For free laying of the step arrangement 2 on the slope 4 is therefore with reference to Fig. 1A First, the rod-shaped limiting element 24 is loosely inserted into certain through openings 14a2, 14b2 in the front foot parts 8a, 8b depending on the inclination of the slope surface 4. Then the tread or stair step body 1 with the inserted limiting element 24 is positioned on the slope surface 4 such that the two front foot parts 8a, 8b face downhill and the two rear foot parts 10a, 10b face uphill.

Finally, the free ends 12 of the front foot parts 8a, 8b and the rear foot parts 10a, 10b are pressed into the slope surface 4 with the foot, for example by part of the weight of the person who is resting on the tread 6, until this enters the through openings 14a2 , 14b2 inserted limiting element 24 rests on the slope surface 4 and thereby further penetration of the ends 12 of the front foot parts 8a, 8b into the slope surface 4 is prevented.

The rod-shaped limiting element 24 and the through openings 14a, 14b can preferably each have a circular cross section. Any cross-section of the rod-shaped delimitation element 24 and the through openings 14a, 14b is conceivable, in particular also a square or rectangular cross-section. Furthermore, the rod-shaped limiting element 24 is formed here, for example, by a rod of reinforced concrete reinforcement.

In addition, the surface of the step surface 6 intended to be entered can be provided with a non-slip pad 26. Such a non-slip pad 26 can in particular consist of a glued-on film with non-slip properties. Alternatively or additionally, the tread surface 6 can also have through holes 19 with serrated wheels, the tines protruding from the tread surface 6 and then also representing an anti-slip device ( Fig. 1 ).

According to another, in Figure 1C In the illustrated embodiment, an even better adjustment of the orientation or inclination of the step surface 6 of the step or stair step body 1 can be achieved by third through openings 16a1, 16a2 in a first rear foot part 10a of the rear foot parts 10a, 10b and in a second rear foot part 10b rear foot parts 10a, 10b fourth, through openings 16b1, 16b2, which are aligned with the third through openings, for example in the transverse direction, are formed, the third through openings 16a1, 16a2 and the fourth through openings 16b1, 16b2 being distinguished by a different vertical level on the rear foot parts 10a, 10b differentiate. As already described above, the further delimiting element 24a can then be inserted, for example, through the lowest through openings 16a1 and 16b1. As a result, the delimiting elements 24, 24a are then in a respective horizontal position.

Then, both for the front and for the rear foot parts 8a, 8b or 10a, 10b, the depth of penetration of their free ends 12 into the slope surface 4 can be limited and thereby the step surface 6 depending on the inclination of the slope surface 4 in the use position of the step or Stair arrangement 2 ideally be aligned horizontally.

A particularly cost-effective production of the step or stair step arrangement 2 also results if the step or stair step body 1 is formed, as here, by a one-piece sheet steel part in which the front foot parts 8a, 8b and the rear foot parts 10a, 10b are bent from the step surface 6 are, as in particular based on 1 to 5 is easy to imagine.

Furthermore, the rear foot parts 10a, 10b and the front foot parts 8a, 8b each preferably have an L-shaped cross section. A web part 28a, 28b is also laterally folded from the step or stair step body 1, which abuts the front foot parts 8a, 8b and the rear foot parts 10a, 10b in a miter 30a, 30b, 30c, 30d. Then, when the tread surface 6 is loaded, the two front foot parts 8a, 8b and the two rear foot parts 10a, 10b can each be supported on the lateral web parts via the miters 30a, 30b, 30c, 30d.

The tread surface 6 preferably has a planar extent such that only one foot of a person can occur there. Alternatively, the tread 6 can also have a larger width in the manner of a step in the transverse direction, so that, for example, a person with both feet can also step on the tread 6 at the same time.

The invention also relates to a step or stair system, in particular a floor or slope-bound staircase consisting of a plurality of step or stair step arrangements 2 described above, which are attached to the slope surface 4 in such a way that the slope surface 4 can be walked on as a whole.

In particular, if the tread surface 6 has a planar extent such that only one foot of a person can appear there, the plurality of tread or stair step arrangements 2 can then, for example, laterally and also with respect to the vertical level on the slope surface 4 can be arranged offset such that their arrangement corresponds to the order in which a person steps up the slope surface 4.

Alternatively, in particular if the tread 4 has a larger width in the manner of a step in the transverse direction, so that a person can step onto the tread with both feet at the same time, the plurality of steps or steps 2 can be arranged on the slope 4 in the manner of steps in one Row must be arranged one behind the other so that they are in alignment with each other. In addition, a locally or continuously curved course of the floor-bound or slope-bound staircase can also be provided, depending on in which the individual step or stair step arrangements 2 are arranged relative to one another on the slope surface 4.

In a further embodiment, according to Fig. 8 and Fig. 9 a tread plate cassette 18, for example made of sheet steel, can be fastened on the tread surface 6 for inserting a tread plate 20, for example by screwing, the tread plate 20 being arranged in the inserted position above and parallel to the tread surface 6.

The tread plate cassette 18, which is made, for example, in one piece from sheet steel, can have a rectangular or square cross section and, for example, have three adjoining profiles 22a, 22b, 22c each with a U-shaped cross section and a base 25 on the edge ( Fig. 9 ), wherein such a profile 22 is arranged on one edge of the bottom 25 and the fourth edge is provided without such a profile, but has fixing means 23 for fixing the tread plate 20 inserted into the profiles 22a to 22c in the tread plate cassette 18 .

In particular, the fixing means can have bendable (sheet metal) tabs 23 arranged on the fourth edge of the bottom 25 of the tread plate cassette 18 such that the tread plate 20 can be inserted into the tread plate cassette 18 in a first position of the tab, such as Fig. 8 and Fig. 9 show, and in a second, compared to the first position here, for example, upwardly bent position of the tabs 23, the tread plate 20 is fixed within the tread plate cassette 18. The tabs 23 can in turn be made in one piece with the tread plate cassette 18 from sheet steel. The tread plate 20 can be made of wood, stone or plastic, for example, in order to produce a desired visual impression.

According to a further embodiment, releasable connecting means can be provided in particular, by means of which a plurality of step or stair step arrangements 2a, 2b can be connected to one another, as in FIG 10 and 11 emerges.

The connecting means can be formed, for example, by a trapezoidal connecting profile 32, of which, seen in the position of use, first engagement elements, for example in the form of first hooks 34, and second engagement elements, for example in the form of second hooks 36, on a second side pointing away from the first side stick out ( Fig. 11 ).

For example, one connection profile 32 is provided for each of the front and rear foot parts 8a, 10a and 8b, 10b, the first hooks 34 of the then two connection profiles 32, for example, in through openings of the rear foot parts 10a, 10b of a first step or stair step arrangement 2a and the second hooks 36 in through openings of the front foot parts 8a, 8b of a second step or step arrangement 2a different from the first step or step arrangement 2a Intervene in step arrangement 2b. The trapezoidal connection profile 32 here, for example, is preferably designed such that the first step or stair step arrangement 2a and the second step or stair step arrangement 2b are connected to one another in particular essentially without a viewing gap. The hooks 34, 36 of the connecting profile 32 are then disengaged from the through openings of the foot parts 8a, 8b or 10a, 10b in order to release the step or stair step arrangements 2a, 2b.
