DETAILED DESCRIPTION

[0047] The compensating element 100 according to the present invention, as shown in FIGS. 1 to 3, is used to extend a modular set of stairs 10, in particular a scaffold stair.

[0048] 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 FIG. 2) and a second end section 112 (see FIG. 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 set of stairs 10, which is usually also made from a round tube. The handrail piece 120 has a longitudinal axis A1 that runs at an angle to the longitudinal axis A2 of the tube 110. The angle is preferably adapted to the pitch of the set of stairs 10.

[0049] As can be seen in particular from FIG. 2, connecting means 150 for connecting the compensating element 100 to a vertical post 200 and/or a vertical post element 210 are arranged on two opposite sides of the tube 110 below the handrail piece 120 (see also FIGS. 4 and 5). The connecting means 150 are connected to the tube 110 via bracket-like holders 151, preferably welded. 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 connector element 220 of the vertical post 200 and/or of the vertical post element 210 (see also FIGS. 4 and 5). In this respect, no tools are required, so that 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.

[0050] As can be seen from FIG. 3, two bracket-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 pipe 110. The height offset is chosen to be the same. In addition, the pipe 110 has a bracket 130 in the area of the second end section 112. A step element 140 can be placed on this (see also FIGS. 4 and 5). The bracket 130 has a rectangular tube 131 that is connected, preferably welded, to the other side of the tube 110 in the extension of a bracket-like holder 151 on the tube. A crossbar element 132 rests on the tubular piece 131 with a flat bearing surface 113, so that the crossbar element 132 projects beyond the tubular piece 131 on both sides. The step element 140 can thus be placed on the bracket 130 from the left and/or from the right. The compensating element 100 can therefore be mounted to the left or right of the stairway. In addition, multiple stairways 10 can be realized.

[0051] If necessary, the compensating element 100 can be connected to at least one diagonal brace 400 in a detachable manner to achieve additional bracing (see also FIG. 8). To fasten the diagonal brace 400, an eyelet 113 (see FIG. 2) is provided in the area of the first end section 111 and a recess 114 (see FIG. 3) is provided in the area of the second end section 112. Fastening is preferably done with screws, as shown in FIG. 7.

[0052] A modular set of stairs 10, in particular a scaffold stairway, is often arranged in a scaffold bay that is spanned by four vertical posts 200. In this case, two vertical posts 200 are available both at the top and bottom of the stairs, to each of which a compensating element 100 can be attached to extend the set of stairs 10. If the set of stairs 10 is to be extended by more than one step, an auxiliary construction is required, whichas shown in FIGS. 4 and 5 by way of examplecan be realized with the help of vertical post elements 210. In this respect, the compensating element 100 is first connected to the vertical post 200 in a detachable manner by means of its connecting elements 150. The further connecting means 150, which are arranged on the side facing away from the vertical post 200, can then be used to create a detachable connection between the compensating element 100 and a vertical post element 210. This then allows-analogous to the vertical post 200the connection of a further compensating element 100.

[0053] As can also be seen from FIGS. 4 and 5, the compensating element 100 can be combined particularly advantageously with a step element 140, which is designed in an angular manner so that it forms a stepping step 141 and a setting step 142. The step element 140 is thus more dimensionally stable and thus more resilient. Optionally, as shown in FIGS. 4 and 5, the setting step 142 can be angled one or more times at its free end 143. This gives the step element 140 an even greater stiffness. In addition, the step element 140 can be placed on a horizontal ledger 300, which provides additional support for the step element 140. In this respect, the horizontal ledger 300 is detachably connected to the vertical stem element 210 by connecting means 310 arranged at the end, which are designed in a similar way to the connecting means 150 of the compensating element 100. The connecting means 310 of the horizontal ledger 300 are brought into engagement with a further recess of the rosette-like connector element 220 of the vertical stem element 210. First, a ledger 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 FIG. 6).

[0054] FIG. 6 shows a multi-stage extension of a set of stairs 10. In this respect, 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, so that any number of stages can be strung together. The angular step elements 140, which rest on the brackets 130 of the compensating elements 100 and on horizontal ledgers 300, can also be clearly seen.

[0055] A set of stairs 10 with three mounted step elements 140 can be seen in FIGS. 8 and 9. These clearly show the indirect connection of two compensating elements 300 via vertical post elements 210, since not every compensating element 100 can be attached to a vertical post 200. To reinforce the structure, the compensating elements 100 are additionally connected by means of diagonal braces 400. Not shown are connector tubes for connecting the handrail pieces 120 of the compensating elements 100, so that a continuous handrail is created.

[0056] FIG. 10 shows a further modular set of stairs (10), which in the present case has been extended by two steps. In this respect, a first compensating 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 compensating element 100 is connected to the first compensating element 100 via the vertical stem element 210. Since the further compensating element 100 is also connected to a vertical stem element 210, at least one further step can be added. In contrast to the preceding examples, the overlying step elements 140 are not angled but are instead flat, so that only stepping steps 141 are formed. This has the advantage that conventional scaffold platforms with end-side fastening straps 144 can be used as step elements 140. The step elements 140 can be connected to the brackets 130 and to the bracket-like holders 151 via the fastening straps 144, so that they rest on two points at each of their two ends. The use of conventional scaffold platforms can further reduce the number of components required for the extension, in particular special components.
