Description

Compensating element for expanding a modular staircase, modular staircase and method for expanding a modular staircase

The invention relates to a compensating element for expanding a modular staircase, in particular a scaffolding staircase. In addition, the invention relates to a modular staircase, in particular a scaffolding staircase, with a compensating element according to the invention and a method for expanding a modular staircase, in particular a scaffolding staircase, using a compensating element according to the invention.

State of the art

Modular stairs can usually be easily dismantled and reassembled in another location. The height conditions at the other location may require height compensation by extending the staircase by one or more steps. The number of steps on a modular staircase should therefore be variable in order to be able to adapt the staircase to the respective local conditions.

DE 202011 002694 U1 discloses a modular staircase that includes an initial module, an end module and at least one expansion module that can be screwed together. Each module forms a level. For each additional stage, another expansion module is placed between the initial module and the final module. In this way, stairs with any number of steps can be created so that height compensation is possible. However, in order to install the further expansion module, the start or end module must first be dismantled, which is time-consuming and cost-intensive.

Based on the prior art mentioned above, this is the case

The invention is based on the task of expanding a modular staircase to simplify any number of steps. In this way, time and costs are to be saved. At the same time, the number of components, especially special components, that are required for expansion or height compensation should be reduced. The same components for extension or height adjustment should be able to be used both at the entrance and at the exit of a staircase.

To solve the problem, the compensation element with the features of claim 1, the modular staircase with the features of claim 12 and the method with the features of claim 16 are proposed. Advantageous developments of the invention can be found in the respective subclaims.

Disclosure of the invention

The proposed compensating element enables an extension of a modular staircase, in particular a scaffolding staircase, both in the area of its entrance and in the area of its exit. This means that the stairs can be expanded in both directions using the compensation element. The compensating element includes: a tube, in particular a rectangular tube, with a longitudinal axis and with a first end section and a second end section, a console for receiving a step element, the console being connected, preferably welded, to the pipe in the area of the second end section and is arranged at an angle, in particular perpendicularly, with respect to the longitudinal axis of the tube,

Connecting means for connecting the pipe to a vertical stem and/or a vertical stem element, wherein the connecting means in the region of the first end section and in the region of the second end section are each connected to the pipe via console-like holders, preferably welded, and wherein the console-like holders are angled, in particular are arranged vertically with respect to the longitudinal axis of the tube.

The proposed compensation element thus forms a cheek and a railing at the same time. To expand a modular staircase by one step, you only need two such compensating elements and a step element that is placed on the consoles of the compensating elements. To extend a staircase by two steps, four compensating elements and two step elements as well as a vertical support element are required. The vertical support element is an element of a conventional vertical support, so that no special component is required. The Vertical support element enables the installation of a compensating element where there is no vertical support. This is usually the case with a multi-stage extension to the staircase, so that the vertical support element replaces the missing vertical support. If there is a vertical support, the compensation element can be connected to it using the connecting means provided. This means that only one type of connecting means is required to connect a compensating element to a vertical post and/or a vertical post element.

If a conventional step element is used, which is already used in the modular staircase, for example, the compensating element is the only special component that is required to expand the staircase. In this way, costs can be saved because fewer special components have to be kept in stock. In this context, it also proves to be advantageous that the compensating element can be mounted both to the left and to the right of the flight of stairs.

According to a preferred embodiment of the invention, a handrail piece is detachably or firmly connected to the pipe in the area of the first end section, preferably welded. The handrail piece has a longitudinal axis which runs at an angle, for example obliquely or perpendicularly, to the longitudinal axis of the tube. In this case, the proposed compensation element simultaneously forms a stringer and a railing with a handrail.

According to a further preferred embodiment of the invention, the tube of the compensating element has at least three, preferably four, bracket-like holders with connecting means. The number of console-like holders increases the connection options. Preferably, at least two console-like holders are arranged on opposite sides of the tube and/or at a height offset from one another. The arrangement of at least two console-like holders on opposite sides of the tube enables a connection of the compensating element to a vertical stem on the one hand and a connection of the compensating element to a vertical stem element on the other hand. Any number of additional compensating elements can be attached to a compensating element, each with the help of a vertical support element. Two console-like holders with connecting means are preferably arranged on each side of the tube. In this case, the compensating element can be connected to a vertical stem and/or a vertical stem element at two points on both sides, both in the area of the first end section and in the area of the second end section Rohrs. The proposed height offset between two console-like holders arranged on opposite sides of the tube preferably corresponds to a step height, so that the necessary height compensation can be achieved here. This has the advantage that you can build a staircase both downwards and upwards with the same compensation element.

Furthermore, the connecting means provided for connecting the compensating element to a vertical stem and/or a vertical stem element each preferably comprise a locking element and a wedge element, which can be brought into engagement with a recess of a rosette-like connecting element of a vertical stem and/or vertical stem element. For this purpose, the locking element is hooked into the recess and fixed within the recess with the wedge element. The connection has the advantage that it can be made without tools. At best, a blow from above on the wedge element is necessary to secure its seat. However, any hard object that is available locally can be used for hitting. To dismantle the compensating element and/or a vertical stem element connected to the compensating element, all that is required is to loosen the seat of the wedge element, remove the wedge element and remove the locking element from the recess. Such connecting means as well as the rosette-like connecting elements provided on the vertical posts and/or vertical post elements for receiving the connecting means are standard, so that no special components are required.

The handrail piece connected to the tube of the compensating element is preferably made from a piece of pipe, so that it can be easily connected to an existing handrail, for example by inserting a connecting piece. In this way, a continuous handrail can be created, which increases safety when climbing the stairs. This is particularly necessary for a staircase that is located in a public space and is accessible to everyone. The pipe section preferably has a circular cross section, so that it can be produced easily and inexpensively and does not pose any risk of injury when walking on the stairs.

The handrail piece is preferably arranged centrally on the tube in the floor plan projection, and preferably not only in the transverse direction, but also in the longitudinal direction of the handrail piece. The central arrangement in the transverse direction has the advantage that the position of the handrail is always the same, regardless of whether the compensating element is installed to the left or right of a flight of stairs. The central arrangement in the longitudinal direction reduces the distance of the handrail piece to an existing handrail and/or another handrail piece of another compensating element. In addition, the same connecting pieces can be used to bridge the gaps. Due to the preferably central arrangement in the longitudinal direction, the handrail piece projects beyond the pipe on both sides in the floor plan projection, preferably in alignment with the console and/or the console-like holders. If the handrail, the console and/or the console-like holders are arranged in alignment, the console and/or the console-like holders are also arranged centrally in the floor plan projection in relation to the tube of the compensating element, so that this is both on the left and on the left Can also be mounted to the right of a flight of stairs.

Furthermore, it is proposed that the console for receiving the step element is made from a piece of pipe, preferably from a rectangular pipe, and that a crossbar element with a flat support surface, which preferably projects beyond the pipe piece on both sides, is arranged on the pipe piece. Using a simple piece of pipe, preferably rectangular pipe, to manufacture the console reduces manufacturing costs. The provision of a crossbar element projecting beyond the pipe section on both sides contributes to the fact that the compensating element can be arranged both to the right and to the left of a flight of stairs, since a support for the step element is created on both sides of the console. Furthermore, multi-flight stairs, i.e. stairs with adjacent flights of stairs, can be easily realized, since a step element can be placed on the console on both sides of the compensating element. This is particularly advantageous for very wide stairs in public spaces, as the width is usually limited for safety reasons and intermediate handrails must be provided. For the first run, two compensating elements and one step element must be installed per step. Each additional run then only requires one more compensating element and one more step element.

Furthermore, it is proposed that the console-like holders are made from a piece of pipe, preferably from a rectangular pipe, so that they can be produced easily and inexpensively. The pipe section preferably has the same cross section as the pipe section of the console, so that the same pipe material can be used. This allows the manufacturing costs to be further reduced.

Furthermore, it is proposed that a console-like holder is arranged at the same height as the console and that a crossbar element is arranged on the console-like holder is. In this way, a further support for a step element is created so that it is optimally supported. For this purpose, the crossbar element is preferably designed analogously to the crossbar element arranged on the console. It preferably has a flat support surface. Furthermore, the crossbar element preferably projects beyond the console-like holder on both sides, so that a support for a step element is created on both sides, for example to realize a multi-flight staircase.

For both the console and the console-like holder, instead of a crossbar element that projects beyond the console or the console-like holder on both sides, a holding element arranged on one side of the console or the console-like holder can be provided to accommodate a step element. Analogous to the crossbar element, this also preferably has a flat support surface for placing a step element. Due to the lateral arrangement, the holding element can only accommodate step elements that are arranged on the same side of the console or the console-like holder. In order to expand the connection options, a holding element can be provided on both sides of the console or the console-like holder.

In a further development of the invention, it is proposed that an eyelet for fastening a diagonal strut is arranged on the tube of the compensating element. With the help of the diagonal brace, the construction can be additionally stiffened if necessary, for example if a modular staircase is to be expanded by not just one but several steps. For this purpose, the diagonal strut attached to a compensating element by means of the eyelet is then connected to a further compensating element, preferably the compensating element of the next, the next or the next stage. The eyelet is preferably arranged in the area of the first end section of the tube.

Furthermore, a recess for fastening a diagonal strut is preferably formed in the tube of the compensating element. The other end of a diagonal strut can be attached via the recess. The recess is therefore preferably arranged in the area of the second end section of the tube. In this case, a diagonal strut extends from the first end section of a first compensating element to the second end section of a further compensating element.

The modular staircase, in particular scaffolding staircase, proposed to solve the problem mentioned at the beginning comprises at least two compensating elements according to the invention and at least one between two Compensating elements arranged step element, wherein the compensating elements are each detachably connected to a vertical stem and / or a vertical stem element via connecting means. The number of compensating elements and step elements depends on the required number of steps, with two compensating elements and one step element being required per step if the staircase is single-flight. In the case of multi-flight stairs, an additional compensating element and a further step element are added for each step, as the compensating element offers connection options on both sides, so that a step element can be placed on both sides.

The vertical stems and/or the vertical stem elements preferably have rosette-like connecting elements, each with at least one recess for receiving the connecting means of the compensating elements. The connecting means of the compensating elements can thus be brought into engagement with the recesses of the rosette-like connecting elements in a simple manner, in particular without tools. This makes the assembly and disassembly of compensating elements easier.

Since vertical supports are usually composed of several elements, the vertical support elements can in particular be such an element. This means that no separate vertical support elements have to be provided, so that the number of components is reduced. Furthermore, it is ensured that vertical stems and vertical stem elements are equipped with the same rosette-like connecting elements in order to attach a compensating element to them.

According to a preferred embodiment of the invention, the compensating elements of a first step extension are each attached to a vertical support. On the side facing away from the vertical stem, the respective compensating element can then be connected to a vertical stem element via the connecting means provided there, in order to then attach the next compensating element to this. In this way, cultivation can be carried out step by step.

As a further development measure, it is proposed that a horizontal bar is arranged between two vertical stem elements and is releasably connected to the vertical stem elements via connecting means arranged at the ends. The horizontal bar contributes to additional stiffening of the structure. In addition, additional support for at least one step element can be realized via the horizontal bar. The connecting means of the horizontal bar located at the end engage preferably in recesses in the rosette-like connecting elements of the vertical stem elements. Ideally, the connecting means are designed to be the same as the connecting means of the compensating elements. This means that the connecting means preferably comprise a locking element and a wedge element for fixing the locking element within a recess of a rosette-like connecting element. Since these connecting elements are standard, a conventional horizontal bar with appropriate connecting means can be used, so that no special component needs to be provided for the horizontal bar.

The step element is preferably angular and/or forms a step and a riser. Due to the angular shape, the step element is more dimensionally stable and therefore more resilient. If the step element forms a riser, the space between two steps can be at least partially closed via the riser, so that safety when walking on the stairs is increased. The riser also reduces the risk of objects falling between two steps. This is particularly advantageous for stairs that are in public spaces.

Advantageously, the free end of the riser is bent at one or more angles. The riser can be placed on a horizontal beam using the fold. In this way, additional support for the step element can be realized. If the edge of the riser is angled several times, it can even encompass the horizontal bar, so that additional position security is provided.

In addition, a method for expanding a modular staircase, in particular a scaffolding staircase, in the area of its entrance and / or exit using at least one compensating element according to the invention and at least one step element is proposed, the compensating element being releasably connected to a vertical stem of the staircase using the connecting means becomes.

By releasably connecting the compensating element to a vertical stem of the stairs, the expansion created with the help of the compensating element can also be reversed. In this way, a variation in the number of steps and thus height compensation is still possible. The detachable connection is preferably made via connecting means which can be brought into engagement with a recess in a rosette-like connecting element of the vertical stem. For example, the connecting means can each comprise a locking element and a wedge element, so that the Detachable connection can be made without tools. Such connecting means are standard.

The same applies to the rosette-like connecting elements of the vertical supports, so that standard components can be used in this regard.

During assembly, the step element is preferably placed on the console of the compensating element. In order to support both ends of the step element, it is further proposed that a second compensating element is releasably connected to a second vertical stem using the connecting means and that the step element is placed in between on the consoles of the compensating elements.

If the staircase is to be expanded by more than just one step, the compensating elements can each be releasably connected to a vertical stem element which has rosette-like connecting elements via further connecting means, which are preferably arranged on the side facing away from the vertical stem. The detachable connection to the vertical stem elements can then be made in the same way as the detachable connection to the vertical stems. For this purpose, the compensating elements advantageously each have corresponding connecting means on opposite sides.

Additional compensating elements can then be connected via the rosette-like connecting elements of the vertical stem elements. A further step element can then be arranged between these, so that the number of steps on the staircase can be increased as desired.

Accordingly, the compensating elements are preferably each detachably connected to a further compensating element via the vertical stem elements. Alternatively or additionally, it is proposed that the compensating elements be releasably connected to a horizontal bar via the vertical stem elements. The horizontal bar provides additional stiffening. Furthermore, depending on the design of the step element, additional support and possibly securing the position of the step element can be provided. For this purpose, the step element is preferably designed angularly, so that a step and a riser are formed. The riser can be angled one or more times at its free end so that it can be supported on the horizontal bar.

The step element can also be a conventional step element or standard component, so that the compensating element is the only special component represents. Since this can be arranged both to the left and right of the flight of stairs, only a single additional component needs to be provided in order to achieve height compensation when assembling a modular staircase.

The connecting means provided on both sides of the compensating element also enable the staircase to be expanded either at its entrance or at its exit, so that the greatest possible flexibility is achieved. Furthermore, multi-flight stairs can be created with the help of the compensating element.

It is also proposed that several compensating elements be connected via at least one diagonal strut. This is particularly advantageous for a multi-stage extension to a staircase, as the construction is additionally stiffened via the diagonal strut. For this purpose, the diagonal strut is connected at one end to a first compensating element and at the other end to a further compensating element, which can in particular be the next, next or next-but-one compensating element which is arranged on the same side of the flight of stairs as the first compensating element.

Detailed description of the drawings

The compensating element 100 according to the invention shown in Figures 1 to 3 serves to expand a modular staircase 10, in particular a scaffolding staircase.

The compensating element 100 has a tube 110, which in the present case is designed as a rectangular tube. The tube 110 has a first end section 111 (see Figure 2) and a second end section 112 (see Figure 3). A handrail piece 120 is arranged on the first end section 111 and is firmly connected to the tube 110, preferably welded. The handrail piece 120 is made of a round tube, so that the handrail piece 120 can be easily connected to a handrail of the stairs 10, which is usually also made of a round tube. The handrail piece 120 has a longitudinal axis A1 which runs obliquely to a longitudinal axis A2 of the tube 110. The angle is preferably adapted to the slope of the stairs 10.

As can be seen in particular from FIG. 2, connecting means 150 for connecting the compensating element 100 to a vertical stem 200 and/or a vertical stem element 210 are arranged below the handrail piece 120 on two opposite sides of the tube 110 (see also FIGS. 4 and 5). The connecting means 150 are connected to the tube 110 via console-like holders 151, preferably welded. The connecting means 150 each include a locking element 152 and a wedge element 153, which can be brought into engagement with a recess in a rosette-like connecting element 220 of the vertical stem 200 and/or the vertical stem element 210 (see also Figures 4 and 5). No tools are required for this, so that the compensating element 100 is easy to close must be assembled and dismantled. The height offset between the two console-like holders 151 corresponds to a step height.

As can be seen from Figure 3, two console-like holders 151 with connecting means 150 are also arranged on two opposite sides in the area of the second end section 112 of the tube 110. The height offset is chosen the same. In addition, the tube 110 has a console 130 in the area of the second end section 112. A step element 140 can be placed on this (see also Figures 4 and 5). The console 130 has a pipe section 131 in the form of a rectangular pipe, which is firmly connected, preferably welded, to the pipe 110 as an extension of a console-like holder 151 on the other side. A crossbar element 132 with a flat support surface 113 rests on the pipe section 131, so that the crossbar element 132 projects beyond the pipe section 131 on both sides. The step element 140 can thus be placed on the console 130 from the left and/or from the right. The compensating element 100 can therefore be mounted to the left or right of the flight of stairs. In addition, multi-flight stairs 10 can be realized.

If necessary, the compensating element 100 can be releasably connected to at least one diagonal strut 400 in order to achieve additional stiffening (see also FIG. 8). To fasten the diagonal strut 400, an eyelet 113 (see Figure 2) is provided in the area of the first end section 111 and a recess 114 (see Figure 3) is provided in the area of the second end section 112. Fastening is preferably carried out with screws, as shown by way of example in FIG.

A modular staircase 10, in particular a scaffolding staircase, is often arranged in a scaffolding field that is spanned by four vertical posts 200. In this case, two vertical supports 200 are available at both the entrance and the exit of the stairs, to each of which a compensating element 100 can be attached to expand the stairs 10. If the staircase 10 is to be expanded by more than one step, an auxiliary construction is required which - as shown by way of example in Figures 4 and 5 - can be realized with the help of vertical support elements 210. For this purpose, the compensating element 100 is first detachably connected to the vertical stem 200 via its connecting means 150. A detachable connection of the compensating element 100 to a vertical stem element 210 can then be established via the further connecting means 150, which are arranged on the side facing away from the vertical stem 200. This then enables - analogous to the vertical support 200 - the connection of a further compensating element 100.

As can also be seen from Figures 4 and 5, the compensating element 100 can be particularly advantageously combined with a step element 140, which is designed to be angular, so that it forms a step 141 and a riser 142. The step element 140 is therefore more dimensionally stable and therefore more resilient. Optionally - as shown in Figures 4 and 5 - the riser 142 can be designed to be angled one or more times at its free end 143. This gives the step element 140 even greater rigidity. In addition, the step element 140 can be placed on a horizontal bar 300, which provides additional support for the step element 140. For this purpose, the horizontal bar 300 is releasably connected to the vertical stem element 210 via connecting means 310 arranged at the end, which are designed analogously to the connecting means 150 of the compensating element 100. For this purpose, the connecting means 310 of the horizontal bar 300 are brought into engagement with a further recess in the rosette-like connecting element 220 of the vertical stem element 210. First, a locking element 311 of the connecting means 310 is inserted into the recess and this is then fixed within the recess with the aid of a wedge element 312 (see also FIG. 6).

A multi-stage extension of a staircase 10 can be seen in FIG. For this purpose, a first compensating element 100 connected to a vertical stem 200 is indirectly connected to a second compensating element 100 via a vertical stem element 210. The second compensating element 100 could be connected in the same way to a third compensating element 100, so that any number of stages can be lined up. The angular step elements 140, which rest on the consoles 130 of the compensating elements 100 and on horizontal bars 300, are also clearly visible.

A staircase 10 with three step elements 140 already mounted can be seen in Figures 8 and 9. These clearly show the indirect connection of two compensation elements 300 via vertical support elements 210, since not every compensation element 100 can be attached to a vertical support 200. To stiffen the construction, the compensating elements 100 are additionally connected by means of diagonal struts 400. Not shown are connecting pipes for connecting the handrail pieces 120 of the compensating elements 100, so that a continuous handrail is created. 10 shows another modular staircase 10, which in the present case is expanded by two steps. For this purpose, a first compensating element 100 is connected on the one hand to a vertical stem 200 and on the other hand to a vertical stem element 210. A further compensating element 100 is connected to the first compensating element 100 via the vertical stem element 210. Since the further compensating element 100 is in turn connected to a vertical stem element 210, at least one further step can be added. In contrast to previous exemplary embodiments, the resting step elements 140 are not angular, but are flat, so that only steps 141 are formed. This has the advantage that conventional scaffolding coverings with end fastening tabs 144 can be used as step elements 140. The step elements 140 can be connected to the consoles 130 and to the console-like holders 151 via the fastening tabs 144, so that they each rest twice at their two ends. By using conventional scaffolding coverings, the number of components required for expansion, especially special components, can be further reduced.
