A set of stairs, in particular a modular set of stairs, with a stairway, as well as a method for manufacturing a set of stairs, in particular a modular set of stairs.

1 . A stairway for a set of stairs, comprising two stringers extending parallel to one another at a distance from one another, and step elements arranged between the stringers and detachably connected to the stringers, which each form a stepping step and a setting step, wherein the step elements rest on first and second brackets, which are arranged on mutually facing inner sides of the stringers. 
     
     
         2 . A stairway according to  claim 1 ,
 wherein the first brackets are arranged at regular intervals from one another in an upper edge region of the insides of the stringers in the installed position and/or the second brackets are arranged at regular intervals from one another in a lower edge region of the insides of the stringers in the installed position.   
     
     
         3 . A stairway according to  claim 1 ,
 wherein the first brackets each form a supporting surface and at least one contact surface arranged at an angle to the supporting surface, wherein preferably the contact surface at the front in the installed position is undercut.   
     
     
         4 . A stairway according to  claim 1 , wherein the setting steps of the step elements are angled at their free ends one or more times. 
     
     
         5 . A stairway according to  claim 1 ,
 wherein the setting steps of the step elements have openings for releasable connection to a further step element located above it in the installed position, wherein preferably each setting step has a plurality of openings which are aligned horizontally and/or arranged at the same height in the installed position.   
     
     
         6 . A stairway according to  claim 1 ,
 wherein the stepping steps of the step elements have at their free ends lugs for detachable connection to a further step element, wherein preferably each stepping step has several lugs which are each aligned at an angle to the stepping step and/or are angled.   
     
     
         7 . A stairway according to  claim 1 ,
 wherein the second brackets each form a bearing surface and/or are each formed in an angular shape, preferably from an angled sheet.   
     
     
         8 . A stairway according to  claim 1 ,
 wherein the stringers each have first and second brackets on the inside and outside, wherein the stringers are preferably designed to be mirror-symmetrical about their longitudinal axis.   
     
     
         9 . A stairway according to  claim 1 ,
 wherein the stringers have connecting means in at least one area, preferably on at least one end face, for releasable connection to a rosette-like connector element of a vertical post.   
     
     
         10 . A stairway according to  claim 1 ,
 wherein the step elements are each produced from a metal sheet by punching and bending, wherein preferably the stepping step and the setting step enclose an angle which is smaller than 90°.   
     
     
         11 . A stairway according to  claim 1 ,
 wherein the stepping steps have a structure and/or embossing at least in some areas.   
     
     
         12 . A stairway according to  claim 1 ,
 wherein the setting steps each have at least one grip opening.   
     
     
         13 . A set of stairs, comprising at least four vertical posts and a stairway according to  claim 1 , wherein preferably the stringers of the stairway are detachably connected to the vertical posts. 
     
     
         14 . A set of stairs according to  claim 13 ,
 wherein the stringer is releasably connected to the vertical posts by means of connectors which each comprise a wedge and/or locking element and engage in a rosette-like connector element of a vertical post.   
     
     
         15 . A set of stairs according to  claim 13 ,
 wherein horizontal ledgers are arranged between the vertical posts and are releasably connected to the vertical posts via connecting means arranged at the ends, which each comprise a wedge and/or locking element and engage in a rosette-like connector element of a vertical post.   
     
     
         16 . A method for producing a set of stairs, comprising the steps of:
 placing at least four vertical posts at a distance from one another so that their ground plan forms a rectangle,   connecting the vertical posts to one another by hanging horizontal bars,   suspending two stringers between each two vertical posts so that they run obliquely parallel to each other from a starting point to an exit point of the set of stairs,   placing step elements, which each form a stepping step and a setting step arranged at an angle in this respect, on consoles connected to the stringers, wherein the step elements are mounted from the bottom upwards and wherein tabs arranged on the stepping step of a step element are inserted into openings in the setting step of an underlying step element and pivoted in until the step element comes to rest on the brackets of the two stringers.   
     
     
         17 . A method according to  claim 16 ,
 wherein, when the tabs are pivoted in, at least one tab is brought into engagement with an undercut region of a bracket of a stringer.   
     
     
         18 . A method according to  claim 16 ,
 wherein, when the step elements are being installed, a free end of the setting steps that is bent once or several times is placed on first brackets of the stringers so that the setting steps each rest on a bearing surface and on at least one contact surface of the first consoles, which is arranged at an angle to the bearing surface.   
     
     
         19 . A stairway according to  claim 1 , wherein the set of stairs is a modular set of stairs. 
     
     
         20 . A method according to  claim 16 , wherein the set of stairs is a modularly constructed set of stairs.
