Storey staircase

The invention relates to a storey staircase whose flight of stairs consists of several steps in the middle are each supported on one of the lower storey ceiling to the upper storey ceiling inclined carrier.

Preferred embodiments of the invention are contained in the protection claims. The scope of protection extends not only on the claimed individual features, but also on their combination.

An embodiment of the invention is shown in the drawing and is described in more detail below. It demonstrate:

Fig.l is a side view of a storey staircase;

Fig. 2 is a perspective view of a step with a support body and the connecting elements in an explosion-like representation;

3 shows a horizontal section through a support body and the adjoining connecting elements corresponding to the section line III-III in Fig.2.

The storey staircase according to the invention is arranged between a lower storey ceiling 10 and an upper storey ceiling 11. The carrier supporting the steps 12 is made up of several identical support bodies 13 arranged one behind the other. For a step IH , the lowermost supporting body 15 is slightly modified compared to the supporting bodies 13; The support body 18 provided for the exit step 17 is also slightly modified compared to the same support bodies 13. It contains a vertical fastening flange 19 »by means of which the stairs are fastened to the upper floor ceiling 11.

The same Stiltzkörper 13 have an upper horizontal Support surface on which the step 12 rests with its center and is thus supported. For fastening the step 12 on the support body 13 are vertical dowels 20 on the upper horizontal support surface of the support body 13 completed. The step 12 has these dowels 20 corresponding blind holes extending from the lower surface 21, with which it is attached to the dowel 20.

Two adjacent support body 13 are each over one with a vertical axis arranged hollow cylinder 22 connected to one another. These are in the direction of the stairs a one behind the other-lying vertical surfaces of the support body 13, namely a front contact surface 23 and a rear contact surface 24 of the surface shape of the hollow cylinder 22 adapted. So these surfaces have the shape of cylinder jacket parts.

The connection of two hollow cylinders 22 to a support body 13 is carried out with two threaded bolts 25, which are in horizontal, parallel, superimposed through bores 26 of the support body 13 are inserted, the front Threaded end 27 of each threaded bolt 25 through a horizontal slot 28 of the one located in the direction of the flight of stairs front hollow cylinder 22 protrudes through into the inner cavity of the cylinder, while the rear Threaded end 29 of threaded bolt 25 through a vertical slot 30 of the rear hollow cylinder in the direction of the flight of stairs 22 protrudes and is located inside the cavity. The attachment is now with the help of washers 31, which are slipped onto the threaded ends 27 and 29 and screwed onto these threaded ends with the aid of Nuts 32 carried out. The washers 31 are

adapted to the shape of the inner surface of the hollow cylinder 22, they have convex contact surfaces 33 with which they fit snugly against the inside of the hollow cylinder 22. A flat contact surface J> k is formed on each washer 31 for the contact of the nut 32.

With the help of the horizontal elongated holes 28, two support bodies 13 arranged one behind the other can be set at an angle arrange to each other. The rear support body I3 can opposite the front support body I3 around the vertical axis of the hollow cylinder connecting the two support bodies 22 can be attached pivoted. In this way, a curved course of the stairs can be formed, with then the steps must be adapted accordingly to this course.

The attachment of the support body 13 to the rear hollow cylinder 22 using a vertical elongated hole 30, through which the rear threaded end 29 of the threaded bolt 25 is inserted, enables the hollow cylinder 22 to move along its vertical axis relative to the support body 13 and in a desired Able to attach. In this way, the height of a step 12 above the adjacent step 12 change.

With the components of the staircase according to the invention so can Different flights of stairs can be built according to curvature and step height. The same components can be used in each case such as support bodies I3, hollow cylinders 22, threaded bolts 25, washers 3I and nuts 32 can be used.
