Description

B a s o. H r a. i. b ng.

The invention relates to a threshold staircase consisting of Steps and associated support brackets.

It is known to produce threshold stairs from individual steps, I. which are placed on consoles. It has been shown, however, that stairs with different inclinations are always designed differently and brackets that are specially adapted to the inclinations must be produced. This often results in the need to make the consoles yourself, which is done, for example, by placing the stairs on sloping iron girders should carry, welded sheet metal pieces abutting one another at right angles or that, for example, triangular blocks are attached to wooden beams, on which the steps are then attached be placed ·.

these disadvantages lead to an often time-consuming individual adjustment eliminate, the invention has therefore set itself the task of creating a prefabricated staircase, preferably in ^ orm a threshold staircase, to create, if possible with a single standardized type of Sfcuf and if possible with a single standardized bracket type on the most varied of inclinations of predetermined inclined stair surfaces such as bars and the like »relative uncomplicated and thus can be created without a great deal of loss of time, with the aim being “the stages preferably by one endless hollow profile to be cut to length on request.

Me solution to this problem is seen in the fact that the support surface. an example of a sickle-shaped console is preferred. is curved outward in such a way that it corresponds to the arc length of the section: a circle, the center of which is itself preferably at the top of the non-curved bracket mounting * -! surface is located and that the on this console can be moved up- | The next step on its underside is recessed in a keh & shaped shape according to the curvature of the console support surface «. On this, n / eisa it is even possible to compensate for the finest, different inclinations of predetermined inclined stair surfaces by opening a such a console is always placed on a stair step only to the extent that something is shifted forwards or backwards, that the'x'rittfläche steta comes to lie horizontally ..

In order to achieve this displaceability, it is proposed that to provide the support surface of the console with a long slot, ctürch the one fastening screw inserted into the step from below will-,. At the same time the consoles also on, for example, different To be able to attach sloping beams that are far apart and accommodate the stairs, is further proposed on the underside of the stairs to attach a continuous dovetail-like groove. into which a sliding piece is introduced to which the console is attached becomes-, the sliding piece subsequently in the Nuta can be locked. The creation of such a groove is in the case of an extruded Erofil. for example easily given ..

Sliding end pieces can be inserted in the same groove, to which side step facings are attached .. Biesa Facings, in turn, can have a! Mute, have in the back. Facings - e.g. in ^ orm one Light band. - can be let in »

The nicely curved bracket fastening has proven to be advantageous. fläclie two outwardly protruding ribs, so that the console except a normal fastening also in the corresponding grooves of the support brackets or the like can be inserted ...

The console, which is preferably made of cast aluminum, has breakthroughs approximately in its center of gravity through which Railing tubes can be inserted .. A further fastening of such tubes can also be given by the fact that the step, if this from an aluminum extrusion profile. exists, a part? - has cross-section into which such tubes are inserted from the side ..

With the aid of the drawing, various exemplary embodiments are described, γ it shows

S ¹ Ig .. 1 a cross section and a side view of a console according to the invention, additionally with a Stsfcfe in cross section,

Fig. 2 is a section according to H - II. In -Fig .. 1, EIg .. 3 to 5 different bracket attachments,

Sig. 6 and 7 the side view of two differently inclined Stairs

and FIG. 8 a section according to VXEI - VIII in FIG. 7.

As FIG. 1 shows, the bearing surfaces 1 of the consoles 2 are curved outward in such a way that they have the arc length b of a circle. correspond, whose center is 4 ·. at the ° pitza of the console mount Fastening surface 5 is located. This fastening surface 5 corresponds to the lower radius edge of an imaginary segment of a circle, which is taken up by the sickle-shaped console. On the_ Console 2 to * ig. 1 there is a step 6, the underside of which is 7 Is recessed in the shape of a throat, this recess being the curvature of the Support surface 1 corresponds. This makes it possible to place level 6 horizontally on the console 2. when it is on differently inclined support beam 8 is attached,

The step 6 is preferably made of an extruded aluminum Hollow profile, which has a dovetail-like groove 9 on the throat-shaped underside, into which a sliding piece 10 is inserted will. The fastening of this piece 10 goes out - ^ ig. 2 emerges. Advantageously, the procedure is that first the piece is inserted loosely and with the fastening screw 11 the step attached to the console 2. through the console longitudinal slot 12 through is, ürst then with the help of center screws I3 the Piece 10 locked *

The attachment of a tee 14 can be carried out in a similar manner, to which a side panel 15 is screwed. This delusion 15 in turn can have a groove 16 on its rear edge, in the one rear step facing 17, for example in S'orm a light strip, can be embedded.

Advantageously, the bracket mounting surface 5 has two obliquely outwardly projecting ribs 18 (see. Fig. 2), so that the bracket 2 can be inserted into a corresponding groove in the support beam 8. According to FIG Groove rail 19 be concreted in or the console 2 is, on wood strips 20 or wooden beams 21 accordingly ^ ig. 4 and. 5 screwed on directly, with the tilting 18 after - ^ if. ° make a good circulation.

In the preferably square partial cross-section 22 of the step 6 according to FIG. 1, ^{a railing tube 23 can be inserted in accordance with I 1} Ig .. 6, the side panel 15 being perforated in this area *. Furthermore, openings 23 are provided in the console 2l in the approximate center of gravity, through which railing tubes can also be inserted in accordance with Mg .. 7 .. This fastening is particularly based on #ig. 8 emerges.

The two WmWPWi 25 and 26 according to Mg. 7 are in section d «pge—« bellt .. The lower stage a · 25 consists of a cut to length sandwich unit, cLJi. That the core layer consists of a foamed plastic, while the Beck layers, for example, can consist of aluminum sheet _f: which can be provided with warts on the cut surface side. Me level 26 is made of wood.

It goes without saying, that the steps or consoles are also made can also consist of other materials, also it goes without saying that through further training, especially through special side panels, the threshold staircase can be given the appearance of a normal full-step staircase ».
