A freestanding modular folding staircase is described in U.S. Pat. No. 3,707,814, and can be assembled from a small number of basic building blocks. units that can be prefabricated and optionally large-scale production. In this case, it is, on the one hand, a line staircase module and, on the other, a landing, except that at least two steel beams are adapted to be supported and supported by said staircase modules and landings. Each staircase module comprises a plurality of horizontal and at least approximately vertical boards that form stairs and are connected to one another by a pair of parallel sides, generally boards or boards or similar building blocks. Each of the landings is, in principle, a sufficiently rigid rectangular slab whose length is at least approximately twice the width of the staircase module. Each carrier comprises a vertically positioned pole and horizontally spaced, mutually spaced beams. The lower bar is adapted to be supported on the base, and each of the higher bar crossings is adapted to attach one end of the respective staircase module and the platform that is arranged between the adjacent staircase modules or respectively. which optionally completes the first and / or last staircase module. In order to carry out the staircase, two spaced beams are generally sufficient. After attaching the modules and landings to the supporting structure, the lower staircase module is obliquely positioned with its lower end resting on the base, and with its upper end, a landing platform adjacent to the adjacent horizontal beams on one side of the carrier. On the rest of the carrier, a further module is attached to said crossbar in addition to said platform with its lower end attached to its higher end by higher horizontal horizontal crossbars of the remaining carrier, on which a further platform is also attached. The next staircase module, with its lower end, is attached to the aforementioned crossbars again together with the aforementioned landing gear, but on the other side of the second mounting bracket. In this way, a staircase is practicable from said staircase modules, landings and supports. In the context of the objectives set out above, this design of the staircase is in many respects flawed. Especially in the case of a larger staircase, which is intended to connect several floors, metal supports are relatively large, heavy and unsuitable for transport and installation. layout. On the other hand, the staircase consists of metal and wooden parts, which requires different • · «

surface treatment processes. The key disadvantage, however, is that the design does not provide the user with any possibility of designing a staircase to suit his or her needs. at the discretion, since it allows only the opposite and height-spaced arrangement and zig-zag arrangement of staircase modules, thereby placing the staircase in a space in the form of an upright square, the dimensions of which, not only in height but also in width and length, must be of dimensions beams, landings and staircase modules are fully and precisely aligned in advance.

The present invention relates to prefabricated modules for the manufacture of a prefabricated staircase, as well as to a staircase consisting of such modules.

For the purposes of this application, the term "staircase module" or simplified "module" means at least during the assembly of the staircase or. while using a single assembly of a predetermined number of stairs and associated sidewalks and other necessary components, each module can be combined with the rest of the modules, and each staging a staircase in any desired configuration. Term "staircase module" or simplified "line module" means an assembly consisting of a predetermined number of steps leading in a straight up direction; down.

Furthermore, the term "left stair module" or simplified "left module" means a set of a predetermined number of stairs which, when walking uphill, form a 90 ° left turn.

Further, the term "right staircase module" or simply "right module" means a set of predefined number of stairs that, when walking uphill, form a 90 ° right turn.

Further, the term "front side of the module" denotes each of the two sides of the module which is intended to either connect to another module and / or platform or to represent the entry side of the module or. staircase or exit the module or. stairs. Thus, for the * «· · · · · · · · · · · · · · · · · · · · · Line elements, the front sides are arranged opposite each other, and for the left or right modules in planes that are perpendicular to each other. .

The term "landing" is a special example of a module without stairs, namely basically horizontally, and in the floor plan a square or rectangular surface, intended for connection or. the passage either between the adjacent modules at each height chosen at each time, or between the module and the door opening or other passage provided in the area of the staircase.

The prefabricated module for the manufacture of the prefabricated staircase of the present invention comprises a predetermined number in height and in the regular walking direction when using the staircase of equidistantly arranged stairs, each of which comprises a horizontal surface and a vertical surface and which, in a linear module, lead straight, the left module uphill in the left turn at an angle of 90 ° and in the right module uphill in the right turn at an angle of 90 °, which are also connected to each other and optionally by means of longitudinal sides. connectable whole. In this case, each module is adapted to either support the base or, with the help of additional support pillars, be held at each appropriate distance from the base and in the area of its front surfaces, which are arranged opposite each other in the line module and in the left or right module. are located in planes that are perpendicular to each other, either interconnected with each adjacent module or with a platform comprising a horizontal surface and a front surface. Said platform, either by means of adjacent modules or by means of additional supporting columns, is kept at a distance from the base and in the area of its facade surfaces or adapted for connection to the respective module or further platform, or to any door opening or other staircase-like passage available at any time. .

According to the invention, it is envisaged that, either as a linear, left or right staircase module or as a platform, a module designed in the area of its front surfaces in each corner area is provided with a column extending in a vertical direction, i.e. orthogonal to the horizontal surfaces of the steps, each of said columns being provided with a centrally arranged and longitudinally extending connecting hole at each end thereof, as well as a connecting nozzle projecting to the side of the respective face surface and provided with a central spaced connecting hole extending in the direction of the respective pillar. Thus, the respective module, respectively. a sensible platform in the area of its pillars and / or couplings by means of pins or pins of similar coupling means which can be inserted into said coupling holes, in a detachable manner, either with another module and / or a platform and / or additional support pillar, which its ends also comprise centrally arranged connecting holes in its longitudinal direction.

Each staircase module is available either

- as in the floor plan, a square line staircase module with respect to the direction of walking while using the lineage of stairs, or

- as in the floor plan, a square left staircase module which, when used uphill, forms a left turn 90 °, or

- as in the floor plan, a square right staircase module in which, when used uphill, stairs (31, 32, 33) form a right bend at 90 ° or, if appropriate, also

- as in the floor plan, a square platform with a horizontal surface.

In the preferred embodiment of the module according to the invention, the larger dimension of the square floor area is less than 80 cm and in particular from 74 to 76 cm. The length, optionally, of the corresponding additional support column is a multiple of at least about 60 cm in length.

The subject of the invention is also a staircase consisting of at least two intermittently coupled modules in accordance with the characteristics described above, in which at least one of the modules is optionally supported by additional supporting columns.

Each of the aforementioned modules is generally prefabricated and is available either in a disassembled or indivisible version. When the module is prefabricated and commercially available in a disassembled embodiment, it is either factory assembled and available to the user in the assembled state or in the kit, i.e. as a set of components from which it is possible to assemble the module at each site first and prepare it for use, i.e. to combine and connect with the rest of the modules available at each time to build the staircase you want.

All components of the individual modules are generally wooden, and their assembly and assembly of the staircase requires the knowledge and skills required, for example. when assembling regular furniture items.
