Description

[0001] Compensation element for extending a modular staircase, modular staircase and method for extending a modular staircase

[0002] The invention relates to a compensating element for extending a modular staircase, in particular a scaffold staircase. Furthermore, the invention relates to a modular staircase, in particular a scaffold staircase, with a compensating element according to the invention, as well as to a method for extending a modular staircase, in particular a scaffold staircase, using a compensating element according to the invention.

[0003] State of the art

[0004] Modular staircases can generally be easily dismantled and reassembled at another location. However, height differences at the new location may require height adjustment by extending the staircase by one or more steps. The number of steps in a modular staircase should therefore be variable to allow the staircase to be adapted to the specific local conditions.

[0005] DE 202011 002694 U1 describes a modular staircase comprising a start module, an end module, and at least one extension module that can be bolted together. Each module forms a step. For each additional step, an additional extension module is placed between the start module and the end module. In this way, staircases with any number of steps can be realized, allowing for height adjustment. However, to install the additional extension module, the start or end module must first be dismantled, which is time-consuming and costly.

[0006] Based on the above-mentioned state of the art, the present

[0007] The invention is based on the task of simplifying the extension of a modular staircase by any number of steps. This saves time and money. At the same time, the number of components, especially special components, required for an extension or height adjustment should be reduced. The same components for extension or height adjustment should be usable both at the start and the end of a staircase.

[0008] To achieve this object, the compensating element having the features of claim 1, the modular staircase having the features of claim 12, and the method having the features of claim 16 are proposed. Advantageous developments of the invention can be found in the respective subclaims.

[0009] Disclosure of the invention

[0010] The proposed compensating element enables the extension of a modular staircase, in particular a scaffold staircase, both in the area of ​​its start and its exit. This means that the staircase can be extended in both directions with the aid of the compensating element. The compensating element comprises: a tube, in particular a rectangular tube, with a longitudinal axis and with a first end section and a second end section, a bracket for receiving a step element, wherein the bracket is connected, preferably welded, to the tube in the area of ​​the second end section and is arranged at an angle, in particular perpendicular, with respect to the longitudinal axis of the tube,

[0011] Connecting means for connecting the pipe to a vertical post and / or a vertical post element, wherein the connecting means are connected, preferably welded, to the pipe in the region of the first end section and in the region of the second end section via bracket-like holders, and wherein the bracket-like holders are arranged at an angle, in particular perpendicular, with respect to the longitudinal axis of the pipe.

[0012] The proposed compensation element thus forms both a stringer and a railing. To extend a modular staircase by one step, only two such compensation elements and a step element are required, which is placed on the brackets of the compensation elements. To extend a staircase by two steps, four compensation elements and two step elements as well as a vertical post element are required. The vertical post element is an element of a conventional vertical post, so no special component is required. The vertical post element enables the installation of a compensation element where no vertical post is present. This is usually the case with a multi-step staircase extension, so the vertical post element replaces the missing vertical post. If a vertical post is present, the compensation element can be connected to it using the provided fasteners.This means that only one type of fastener is required to connect a compensating element to a vertical post and / or a vertical post element.

[0013] If a conventional step element is used, such as one already used in a modular staircase, the leveling element is the only special component required to extend the staircase. This saves costs because fewer special components need to be kept in stock. Another advantage in this context is that the leveling element can be mounted on either the left or right side of the staircase.

[0014] According to a preferred embodiment of the invention, a handrail piece is detachably or permanently connected, preferably welded, to the pipe in the region of the first end section. The handrail piece has a longitudinal axis that runs at an angle, for example, obliquely or perpendicularly, to the longitudinal axis of the pipe. In this case, the proposed compensating element simultaneously forms a stringer and a railing with a handrail.

[0015] 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 connection options increase with the number of bracket-like holders. Preferably, at least two bracket-like holders are arranged on opposite sides of the tube and / or offset in height from one another. The arrangement of at least two bracket-like holders on opposite sides of the tube enables the compensating element to be connected to a vertical post on the one hand and the compensating element to be connected to a vertical post element on the other. Any number of additional compensating elements can thus be attached to a compensating element, each with the aid of a vertical post element. Preferably, two bracket-like holders with connecting means are arranged on each side of the tube.In this case, the compensating element can be connected to a vertical post and / or a vertical post element at two points on each side, both in the area of ​​the first end section and in the area of ​​the second end section of the tube. The proposed height offset between two bracket-like holders arranged on opposite sides of the tube preferably corresponds to a step height, so that the necessary height adjustment can be achieved. This has the advantage that the same compensating element can be used to construct both downward and upward staircases.

[0016] Furthermore, the connecting means provided for connecting the compensating element to a vertical post and / or a vertical post element preferably each 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 post and / or vertical post element. For this purpose, the locking element is suspended in the recess and fixed within the recess with the wedge element. The connection has the advantage that it can be made without tools. At most, a blow from above on the wedge element is necessary to secure its seat. However, any hard object available on site can be used for the blow. To disassemble the compensating element and / or a vertical post element connected to the compensating element, it is only necessary to loosen the seat of the wedge element, remove the wedge element, and take the locking element out of the recess.Such connecting elements as well as the rosette-like connecting elements provided on the vertical posts and / or vertical post elements for receiving the connecting elements are standard, so that no special components are required.

[0017] The handrail section connected to the tube of the compensating element is preferably made from a single piece of pipe, allowing it to be easily connected to an existing handrail, for example, by inserting a connector. This creates a continuous handrail that increases safety when using the stairs. This is particularly necessary for stairs located in public spaces and accessible to everyone. The pipe section preferably has a circular cross-section, allowing it to be manufactured easily and cost-effectively and posing no risk of injury when using the stairs.

[0018] The handrail section is preferably arranged centrally on the tube in the floor plan projection, and furthermore preferably not only in the transverse direction, but also in the longitudinal direction of the handrail section. The central arrangement in the transverse direction has the advantage that the position of the handrail is always the same, regardless of whether the compensation element is mounted to the left or right of a flight of stairs. The central arrangement in the longitudinal direction reduces the distance between the handrail section and an existing handrail and / or another handrail section of another compensation element. In addition, the same connecting pieces can be used to bridge the distances. Due to the preferably central arrangement in the longitudinal direction, the handrail section projects beyond the tube on both sides in the floor plan projection, preferably in line with the bracket and / or the bracket-like holders. If the handrail, the bracket and / or the bracket-like holders are arranged in line, the...The console and / or the console-like holders are also arranged centrally in the floor plan projection in relation to the tube of the compensation element, so that this can be mounted both to the left and to the right of a flight of stairs.

[0019] Furthermore, it is proposed that the bracket for receiving the step element be made from a piece of pipe, preferably a rectangular pipe, and that a cross-bar element, preferably projecting beyond the pipe on both sides and having a flat support surface, be arranged on the pipe section. The use of a simple piece of pipe, preferably a rectangular pipe, for manufacturing the bracket reduces manufacturing costs. The provision of a cross-bar element projecting beyond the pipe section on both sides contributes to the fact that the compensation element can be arranged both to the right and left of a flight of stairs, since a support for the step element is created on both sides of the bracket. Furthermore, multi-flight staircases, i.e. staircases with adjacent flights of stairs, can be easily realized since a step element can be placed on the bracket on either side of the compensation element.This is particularly advantageous for very wide staircases in public spaces, where the flight width is usually limited for safety reasons and intermediate handrails must be provided. For the first flight, two leveling elements and one step element must be installed per step. Each subsequent flight then requires only one additional leveling element and one additional step element.

[0020] It is further proposed that the bracket-like holders be made from a single piece of tubing, preferably a rectangular tubing, so that they can be manufactured easily and cost-effectively. Preferably, the tubing has the same cross-section as the tubing of the bracket, so that the same tubing material can be used. This further reduces manufacturing costs.

[0021] Furthermore, it is proposed that a bracket-like holder be arranged at the same height as the bracket, and that a crossbar element be arranged on the bracket-like holder. In this way, an additional support for a step element is created, so that the step element is optimally supported. For this purpose, the crossbar element is preferably designed analogously to the crossbar element arranged on the bracket. It preferably has a flat support surface. Furthermore, the crossbar element preferably projects beyond the bracket-like holder on both sides, so that a support for a step element is created on each side, for example for the realization of a multi-flight staircase.

[0022] For both the console and the console-like holder, instead of a crossbar element that projects beyond the console or console-like holder on both sides, a holding element arranged on one side of the console or 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 its lateral arrangement, the holding element can only accommodate step elements that are arranged on the same side of the console or console-like holder. To expand the connection options, a holding element can be provided on each side of the console or console-like holder.

[0023] In a further development of the invention, it is proposed that an eyelet for attaching a diagonal brace be arranged on the tube of the compensating element. The diagonal brace can be used to provide additional stiffening to the structure if necessary, for example, if a modular staircase is to be extended by not just one but several steps. The diagonal brace, attached to a compensating element by means of the eyelet, is connected at the other end to another compensating element, preferably the compensating element of the next, next-but-one, or next-but-one step. The eyelet is preferably arranged in the region of the first end section of the tube.

[0024] Furthermore, a recess for attaching a diagonal strut is preferably formed in the tube of the compensating element. The other end of each diagonal strut can be attached via the recess. The recess is therefore preferably arranged in the region 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 another compensating element.

[0025] The modular staircase, in particular a scaffold staircase, further proposed to achieve the aforementioned object comprises at least two compensating elements according to the invention and at least one step element arranged between two compensating elements, wherein the compensating elements are each detachably connected to a vertical post and / or a vertical post 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 has a single flight. In the case of multi-flight staircases, a further compensating element and a further step element are added for each step, since the compensating element offers connection options on both sides, so that a step element can be placed on either side.

[0026] Preferably, the vertical posts and / or the vertical post elements 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 easily brought into engagement with the recesses of the rosette-like connecting elements, in particular without the need for tools. This facilitates the assembly and disassembly of the compensating elements.

[0027] Since vertical posts are usually composed of multiple elements, the vertical post elements can be a single element. This means that no separate vertical post elements need to be kept in stock, thus reducing the number of components. Furthermore, it ensures that the vertical posts and vertical post elements are equipped with the same rosette-like connecting elements for attaching a compensating element.

[0028] According to a preferred embodiment of the invention, the compensating elements of a first step extension are each attached to a vertical post. On the side facing away from the vertical post, the respective compensating element can then be connected to a vertical post element using the connecting means provided there, in order to then attach the next compensating element to it. In this way, the extension can be installed step by step.

[0029] As a further development, it is proposed that a horizontal bar be arranged between two vertical post elements and detachably connected to the vertical post elements via connecting means arranged at the ends. The horizontal bar contributes to additional stiffening of the structure. Furthermore, additional support for at least one step element can be realized via the horizontal bar. The connecting means arranged at the ends of the horizontal bar preferably engage in recesses of the rosette-like connecting elements of the vertical post elements. Ideally, the connecting means are designed in the same way as the connecting means of the compensation elements. This means that the connecting means preferably comprise a bar element and a wedge element for fixing the bar element within a recess of a rosette-like connecting element.Since these connecting elements are standard, a conventional horizontal bar with appropriate connecting elements can be used, so that no special component needs to be kept for the horizontal bar either.

[0030] The step element is preferably angular and / or forms a tread and a riser. The angular shape makes the step element more rigid and therefore more resilient. If the step element forms a riser, the riser can at least partially close the space between two treads, thus increasing safety when using the stairs. Furthermore, the riser reduces the risk of objects falling between two treads. This is particularly advantageous for staircases located in public spaces.

[0031] Advantageously, the free end of the riser is beveled at one or more angles. The bevel allows the riser to be placed on a horizontal bar. This provides additional support for the step element. If the riser's bevel is beveled at multiple angles, it can even wrap around the horizontal bar, providing additional stability.

[0032] Furthermore, a method for extending a modular staircase, in particular a scaffold staircase, in the area of ​​its start and / or exit using at least one compensating element according to the invention and at least one step element is proposed, wherein the compensating element is detachably connected to a vertical post of the staircase by means of the connecting means.

[0033] The detachable connection of the leveling element to a vertical post of the staircase allows the extension created by the leveling element to be reversed. This allows for a variation in the number of steps and thus height adjustment. The detachable connection is preferably made using connecting elements that can be brought into engagement with a recess in a rosette-like connecting element of the vertical post. For example, the connecting elements can each comprise a locking element and a wedge element, allowing the detachable connection to be created without tools. Such connecting elements are standard.

[0034] The same applies to the rosette-like connecting elements of the vertical posts, so that standard components can be used in this regard.

[0035] During assembly, the step element is preferably placed on the bracket of the compensating element. To support both ends of the step element, it is further proposed that a second compensating element be detachably connected to a second vertical post using the connecting means, and that the step element be placed on the brackets of the compensating elements between them.

[0036] If the staircase is to be extended by more than one step, the compensating elements can each be detachably connected to a vertical post element via additional connecting means, preferably located on the side facing away from the vertical post, which has rosette-like connecting elements. The detachable connection to the vertical post elements can then be established in the same way as the detachable connection to the vertical posts. For this purpose, the compensating elements advantageously have corresponding connecting means on opposite sides.

[0037] Additional leveling elements can then be connected via the rosette-like connecting elements of the vertical post elements. An additional step element can then be placed between these, allowing the number of steps in the staircase to be increased as desired.

[0038] Preferably, the compensation elements are each detachably connected to a further compensation element via the vertical post elements. Alternatively or additionally, it is proposed that the compensation elements be detachably connected to a horizontal bar via the vertical post elements. The horizontal bar provides additional stiffening. Furthermore, depending on the design of the step element, additional support and, if necessary, positional securing of the step element can be provided. For this purpose, the step element is preferably designed in an angled manner, so that a tread and a riser are formed. The riser can be angled once or multiple times at its free end so that it can be supported on the horizontal bar.

[0039] The step element can also be a conventional step element or standard component, so the leveling element is the only special component. Since this can be positioned either to the left or right of the flight of stairs, only a single additional component is required to achieve height adjustment during the installation of a modular staircase.

[0040] The connecting elements on both sides of the compensating element also allow the staircase to be extended either at the start or at the end, providing maximum flexibility. Furthermore, multi-flight staircases can be created using the compensating element.

[0041] It is further proposed that several compensating elements be connected via at least one diagonal brace. This is particularly advantageous in a multi-stage extension of a staircase, as the diagonal brace provides additional stiffening to the structure. For this purpose, the diagonal brace 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, the next-but-one, or the next-but-one compensating element located on the same side of the flight of stairs as the first compensating element.

[0052] Detailed description of the drawings

[0053] The compensation element 100 according to the invention shown in Figures 1 to 3 serves to extend a modular staircase 10, in particular a scaffold staircase.

[0054] The compensating element 100 has a tube 110, which in this 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, preferably welded, to the tube 110. The handrail piece 120 is formed from a round tube, so that the handrail piece 120 can be easily connected to a handrail of the staircase 10, which is usually also made of a round tube. The handrail piece 120 has a longitudinal axis A1 that runs obliquely to a longitudinal axis A2 of the tube 110. The angle is preferably adapted to the gradient of the staircase 10.

[0055] As can be seen in particular from Figure 2, connecting means 150 for connecting the compensating element 100 to a vertical post 200 and / or a vertical post element 210 are arranged below the handrail piece 120 on two opposite sides of the tube 110 (see also Figures 4 and 5). The connecting means 150 are connected, preferably welded, to the tube 110 via bracket-like holders 151. The connecting means 150 each comprise a locking element 152 and a wedge element 153, which can be brought into engagement with a recess of a rosette-like connecting element 220 of the vertical post 200 and / or the vertical post element 210 (see also Figures 4 and 5). No tools are required for this, so the compensating element 100 is easy to assemble and disassemble. The height offset between the two bracket-like holders 151 corresponds to a step height.

[0056] As can be seen from Figure 3, in the area of ​​the second end section 112 of the tube 110, two bracket-like holders 151 with connecting means 150 are also arranged on two opposite sides. The height offset is selected to be the same. In addition, the tube 110 has a bracket 130 in the area of ​​the second end section 112. A step element 140 can be placed onto this (see also Figures 4 and 5). The bracket 130 has a tube section 131 in the form of a rectangular tube, which is firmly connected, preferably welded, to the tube 110 as an extension of a bracket-like holder 151 on the other side of the tube 110. A cross-bar element 132 with a flat support surface 113 rests on the tube section 131, so that the cross-bar element 132 projects beyond the tube 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 compensation element 100 can therefore be mounted to the left or right of the staircase. Furthermore, multi-flight staircases 10 can be realized.

[0057] If necessary, the compensating element 100 can be detachably connected to at least one diagonal strut 400 to achieve additional stiffening (see also Figure 8). For fastening 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 Figure 7.

[0058] A modular staircase 10, in particular a scaffold staircase, is often arranged in a scaffold bay spanned by four vertical posts 200. In this case, two vertical posts 200 are available at both the start and the exit of the staircase, to each of which a compensating element 100 can be attached to extend the staircase 10. If the staircase 10 is to be extended by more than one step, an auxiliary structure is required, which - as shown by way of example in Figures 4 and 5 - can be realized with the aid of vertical post elements 210. For this purpose, the compensating element 100 is first detachably connected to the vertical post 200 via its connecting means 150. A detachable connection of the compensating element 100 to a vertical post element 210 can then be established via the further connecting means 150, which are arranged on the side facing away from the vertical post 200.This then enables - analogous to the vertical post 200 - the connection of another compensation element 100.

[0059] As can also be seen from Figures 4 and 5, the compensating element 100 can be particularly advantageously combined with a step element 140 that is angled, forming a tread 141 and a riser 142. This makes the step element 140 more rigid and thus more resilient. Optionally, as shown in Figures 4 and 5, the riser 142 can be angled one or more times at its free end 143. This imparts even greater rigidity to the step element 140. Furthermore, 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 detachably connected to the vertical post 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 of the rosette-like connecting element 220 of the vertical post element 210. First, a locking element 311 of the connecting means 310 is inserted into the recess and then fixed within the recess with the aid of a wedge element 312 (see also Figure 6).

[0060] Figure 6 shows a multi-step extension of a staircase 10. A first compensating element 100, connected to a vertical post 200, is indirectly connected to a second compensating element 100 via a vertical post element 210. The second compensating element 100 could be connected in the same way to a third compensating element 100, allowing any number of steps to be arranged in a row. Also clearly visible are the angular step elements 140, which rest on the brackets 130 of the compensating elements 100 and on horizontal bars 300.

[0061] A staircase 10 with three already mounted step elements 140 can be seen in Figures 8 and 9. These clearly show the indirect connection of two compensation elements 300 via vertical post elements 210, since not every compensation element 100 can be attached to a vertical post 200. To stiffen the structure, the compensation elements 100 are additionally connected by means of diagonal struts 400. Not shown are connecting tubes for connecting the handrail pieces 120 of the compensation elements 100, so that a continuous handrail is created. Figure 10 shows another modular staircase 10, which in this case has been extended by two steps. For this purpose, a first compensation element 100 is connected on the one hand to a vertical post 200 and on the other hand to a vertical post element 210. A further compensation element 100 is connected to the first compensation element 100 via the vertical post element 210.Since the additional compensating element 100 is in turn connected to a vertical post element 210, at least one additional step can be added. In contrast to previous exemplary embodiments, the supported step elements 140 are not angular, but flat, so that only treads 141 are formed. This has the advantage that conventional scaffolding planks with end-side fastening tabs 144 can be used as step elements 140. The fastening tabs 144 can be used to connect the step elements 140 to the brackets 130 and to the bracket-like holders 151, so that they each rest twice at their two ends. By using conventional scaffolding planks, the number of components required for the extension, in particular special components, can be further reduced.
