Die Erfindung betrifft ein Rollgitter, bei dem bügeiförmig abgebogene Zwischenglieder beiderseits an waagerechte, gerade Stäbe mittels Gelenkbunden angeschlossen sind.
Bei den bekannten Rollgittern dieser Art sind die sich überlappenden Enden der an den Außenseiten des Rollgitters liegenden Zwischenglieder durch Nietung gelenkig miteinander verbunden. Diese Verbindung bringt ίο jedoch erhebliche Nachteile mit sich, insbesondere deshalb, weil mit dem Absprengen einer dieser Nieten die unbehinderte Aufrollbarkeit des Rollgitters aufgehoben ist und zur Wiederherstellung der Gelenkverbindung ein vollkommener Ausbau des Rollgitters erforderlich wird.
The invention relates to a rolling grille in which bow-shaped bent intermediate links are connected on both sides to horizontal, straight bars by means of hinged collars.
In the known rolling grilles of this type, the overlapping ends of the intermediate members lying on the outer sides of the rolling grill are connected to one another in an articulated manner by riveting. However, this connection brings with it considerable disadvantages, in particular because if one of these rivets breaks off, the unimpeded rollability of the rolling grille is canceled and a complete removal of the rolling grille is required to restore the articulated connection.
Das Neue der Erfindung besteht darin, daß die Enden der ,äußersten ZwischengUeder mit rechtwinkligen Abbiegungen versehen sind, die an den waagerechten, geraden Stäben anliegen und an diesen mittels Gelenkbunden befestigt sind, derart, daß die Abkröpfungen an den Enden der rechtwinkligen Abbiegungen den Bund in seiner Lage festhalten. Durch diese nietlose Verbindung der an den Außenseiten liegenden Zwischenglieder, mit den geraden Stäben werden die mit der bekannten Nietverbindung verbundenen Nachteile vermieden.The novelty of the invention consists in the fact that the ends of the outermost intermediate layers are provided with right-angled bends that rest against the horizontal, straight bars and are attached to these by means of hinges, such that the bends Hold the collar in place at the ends of the right-angled turns. This rivetless connection of the Intermediate links lying on the outside, with the straight bars are those with the known Riveted connection avoided disadvantages. Eine der Erfindung entsprechende Rollgitterausführung ist auf der Zeichnung in Abb. ι im Ausschnitt in Ansicht dargestellt. Die Abb. 2 und 3 zeigen eine Ansicht und Draufsicht der Gittergliederverbindung an der Außenseite des Rollgitters.A rolling grille design corresponding to the invention is shown in FIG Fig. Ι shown in detail in view. Figs. 2 and 3 show a view and Top view of the lattice linkage on the outside of the rolling grille. Wie ersichtlich, besteht das Rollgitter aus den üblichen waagerechten Stäben« und den zwischen diese 'eingesetzten, bügeiförmig abgebogenen Zwischengliedern b, die durch die Bunde c gelenkig miteinander verbunden sind.As can be seen, the rolling grille consists of the usual horizontal bars and the intermediate links b, which are bent in a bow-shaped manner and are connected to one another in an articulated manner by the collars c. Die an den Außenseiten des Rollgitters liegenden Zwischenglieder b sind in der Biegungsebene rechtwinklig abgebogen und fügen sich mit diesen Abkröpfungen an die gerade durchlaufenden Stäbe« an. Zur gelenkigen Lagerung der äußersten Zwischenglieder b und der geraden Stäbe α dienen die Gelenkbunde/. Um den Gelenkbunden/ hierbei einen Halt zu geben, sind die freien Enden der Zwischenglieder b mit winklig abstehenden Abkröpfungen^· versehen. The intermediate links b located on the outside of the rolling grille are bent at right angles in the plane of the bend and, with these bends, adjoin the bars that are just passing through. The articulated collars / serve to articulate the outermost intermediate links b and the straight bars α. In order to give the hinges a hold, the free ends of the intermediate links b are provided with bent bends that protrude at an angle. Patentansi'Kucij :Patentansi'Kucij: Rollgitter, bei dem bügeiförmig abgebogene Zwischenglieder beiderseits an waagerechte, gerade Stäbe mittels Gelenkbunden angeschlossen sind, dadurch gekennzeichnet, daß die Enden der äußersten Zwischenglieder (b) mit rechtwinkligen Abbiegungen versehen sind, die an den waagerechten, geraden Stäben (a) anliegen und an diesen mittels Gelenkbunden (/) befestigt sind, wobei Abkröpfungen (g) an den Enden der rechtwinkligen Abbiegung den Bund in seiner Lage festhalten. Rolling grille, in which bow-shaped bent intermediate links are connected on both sides to horizontal, straight rods by means of hinged collars, characterized in that the ends of the outermost intermediate links (b) are provided with right-angled bends which rest on the horizontal, straight rods (a) and on them are fastened by means of hinge collars (/), with bends (g) at the ends of the right-angled bend holding the collar in place.
