Gegenüber bekannten Treppenaufzügen mit zu einem endlosen Bande verbundenen wagerechten Stufenkörpern, die bei der Bewegung sich nur in senkrechter Richtung gegen einander verschieben, kennzeichnet sich der den Gegenstand der vorliegenden Erfindung bildende Treppenaufzug durch zu einem endlosen Bande mit einander verbundene, sich überlappende Glieder, von welchen durch eine eigenthümliche Führung des Bandes eine Gruppe die Trittstufen und eine andere Gruppe die Satzstufen bilden. Zu diesem Zwecke sind für die Führungsrollen des Bandes zwei verschieden ausgeführte und in einander übergehende Vorwärtsführungen und eine Rückwärtsführung an jeder Seite des Treppenaufzuges angeordnet, derart, dafs durch die Vorwärtsführungen die Bildung der Tritt- und Satzstufen erfolgt, während durch die Rückwärtsführung das um eine obere getriebene Rolle geführte Band gerade ausgerichtet und um eine untere Rolle zur wiederholten Bildung der Tritt- und Satzstufen geführt wird.Opposite known stair lifts with horizontal ones connected to form an endless gang Stepped bodies that move against each other only in a vertical direction move, characterizes the subject of the present invention forming Stair lift through overlapping links connected to one another in an endless band, one of which is through a peculiar leadership of the band one group the steps and another group form the sentence levels. For this purpose there are two guide rollers for the belt differently designed and merging forward guides and a backward guide arranged on each side of the staircase elevator, in such a way that the forward guides facilitate the formation of the and sentence steps takes place, while through the backward guidance the one driven around an upper one Roll of guided tape straightened and repeated around a lower roll Formation of step and sentence steps is guided.

Die Glieder 2 des endlosen ,Bandes 1 sind durch Verbindungsbolzen 3 verbunden, die durch Augen der senkrechten Seitenwangen 4 führen, und bilden eine lückenlose Trittfläche. In passenden Abständen von einander, entsprechend der Breite der zu bildenden Trittstufen, sind mit den betreffenden Gliedern auf der Innenseite des Bandes stärkere Führungsbolzen 5 und 6 in Verbindung durch Ringe 7, die die Bolzen umschliefsen und Augen für die Aufnahme der Bolzen 3 tragen (Fig. 3), so dafs das Band an den Bolzen 5 und 6 sich ein- oder ausbiegen kann.The links 2 of the endless, belt 1 are connected by connecting bolts 3, which through eyes of the vertical side cheeks 4 lead, and form a seamless step surface. At appropriate distances from each other, accordingly the width of the steps to be formed, stronger guide pins 5 and 6 are connected to the relevant links on the inside of the belt by rings 7, which enclose the bolts and have eyes for receiving the bolts 3 (Fig. 3), so that the tape on the bolts 5 and 6 can bend in or out.

Die Enden der Bolzen 5 und 6 sind (Fig. 7) mit Rollen versehen. Von diesen laufen bei der Bewegung des Bandes mittelst der oberen getriebenen Rolle 11 die Führungsrollen der Bolzen 5 durch die oberen Vorwärtsführungen 8 (Fig. ι und 7) an beiden Seiten der Stufenbahn, die Rollen der längeren Bolzen 6 dagegen durch die unteren und oben und unten durch wagerechte Uebergänge mit R verbundene VorwärtsführYingen 9, ebenfalls an beiden Seiten des Treppenaufzuges. Beide Vorwärts führungen gehen passend in die Rückwärtsführungen 10 über (Fig. 1), durch welche die Rollen 5 und 6 bei gestreckter Lage des unteren Trums des Bandes ihren Weg abwärts nehmen.The ends of the bolts 5 and 6 are provided with rollers (Fig. 7). Of these run at the movement of the belt by means of the upper driven roller 11, the guide rollers of the Bolts 5 through the upper forward guides 8 (Fig. Ι and 7) on both sides the stepped track, the rollers of the longer bolts 6, however, through the lower and upper and at the bottom by horizontal transitions connected to R forwards guide Yingen 9, likewise on both sides of the stair lift. Both forward guides go into the Reverse guides 10 over (Fig. 1), through which the rollers 5 and 6 when stretched The location of the lower run of the belt will take its way downwards.

Das Band läuft um die untere Rolle 12, die am Umfange mit vier Aussparungen für Aufnahme der Bolzen 5 und 6 versehen ist.The tape runs around the lower roller 12, which has four recesses for Receiving the bolts 5 and 6 is provided.

Claims

The upper roller 11 of smaller diameter contains only one such recess for these bolts 5, while a smaller recess is provided to accommodate the thinner connecting bolts 3. The part of the band that has passed over the lower roller 12 begins to adjust itself again in stepped form, in that the rollers of the longer guide pins 6 are guided into the lower forward guides 9, which have a corresponding groove 18 for the pin end, while the rollers the shorter bolts 5 take the path through the upper forward guide 8. The upper run of the endless belt, which forms treads and set steps, leads from a lower-lying platform 14 to a higher-lying 15 (FIG. 1) The uppermost step and joins the curved part of the band to avoid gaps in which objects could jam in. This is not to be feared for the connection to the lower platform 14. The band bending out and in when the steps are formed takes place close to the lower platform by the fact that the bolts 5 and 6 take different paths: First there is a step, then a set step, then again a step and so on. The sentence steps are not vertical, but inclined, as in Fig. 1. The steps can then be chosen narrower and the distance between the latter is larger, so that there is enough space between one person and another. Once you have reached the upper platform, you can comfortably step onto it. The individual links can be made of wrought iron or malleable cast iron and can be given the shapes shown in FIGS. 8 to 12. Each link is provided with a tongue 16 which is concentric with the relevant connecting bolt 3 and which overlaps or overlaps from the adjacent edge of the next front link in the upward run. is underlap in the descending strand. Links according to Fig. 8 are used for the parts of the belt lying between the guide pins 5 and 6, links according to Figs. 9 and 10 at the point of connection between the rear edge of the treads and the lower edge of the set steps, as in AB (Fig 3) can be seen. The edges of link B are cut away and the edges of link A beveled at 17 so that when the sentence step is formed, link B can step over A, as in Fig. 3. Links according to Figs. 11 and 12, with C and D, are used, as in FIG. 3, at the point where the sentence steps are connected to the front edge of the treads. Here the tongue extends over the full width of the step surface, and the side cheeks 4 are cut concentrically to the connecting bolt for the entry of the tongue of the next link. This avoids the formation of a gap at the front edge of the steps. In general, the links, which in other respects can undergo various changes, are formed in such a way that gaps are avoided at the point of connection between step and sentence steps. The band could also be made of leather or other flexible material instead of hinged links made of metal, but the latter are preferable. Sponsorship τ claims:

1. Stair lift with existing from individual articulated links connected to each other endless belt, characterized in that the endless belt by means of guide pins (5, 6) in forward guides (8, 9) and a reverse guide (10) is guided in such a way that when the belt is moved the treads Record levels are formed by the fact that the bolts (5,6) different ways, namely the former into the guides (8), the latter into the guides (9) to take.

2. Embodiment of the 1. referred to Stair lift, in which in the lower forward guide (9) and in the backward guide (10) a corresponding. corresponding lateral groove (18) for the end of the bolt (6) is provided, which is longer than the bolts (5) are designed in such a way that the rollers of the bolts (6) through the Nuthen (18) out, take the path into the guide (9), the roles of Bolt (5), however, the way into the upper guide (8).

3. Embodiment of the stair lift referred to in 1., in which the individual links (2) of the belt to the connecting bolts (3) have concentric tongues (i6 ~) which are overlapped by the next links. '..' ■■ '. ■' ■
