Description

Die Erfindung bezweckt eine weitere Ausbildung der für Bauzwecke bestimmten Hebevorrichtung nach Patent 369652, bei welcher der Seilrollenträger an einer in ihrer Länge verstellbaren Ouerspreize sitzt, welche in eine Mauerwerksöffnung eingesetzt wird. Diese Vorrichtung soll nun auch zwischen schrägen Innenflächen des Mauerwerks unverrückbar festhaltend eingespreizt werden können. Gemaß der Erfindung sind dazu an den Enden der in sich verstellbaren Ouerspreize zum Anpressen an die Mauerwerkswandungen Anpreßplatten mittels Kugelgelenke angefügt, welch letztere die Anpassung der Anpreßplatten an die Schräge der Wandungen ermöglichen, so daß durch den Spreizdruck das Gerät ohne weitere Hilfsmittel in seiner jeweiligen Lage festgehalten wird. Die Zeichnung veranschaulicht eine der Erfindung entsprechend ausgeführte Vorrichtung ao in Abb. 1 in Draufsicht,
in Abb. 2 in Vorderansicht;
Abb. 3 zeigt die Enden der Spreize im Schnitt. Wie bei dem Gegenstande des Hauptpatents ist der mittels der Stützen q auf der unteren Mauerfläche s gestützte Träger δ der Seilrolle a an dem Rohr e befestigt, in welchem die Stange h verschiebbar und mittels einer Klemmvorrichtung k ein- und feststellbar gelagert ist. Gemäß der Erfindung sind die Anpreßplatten g mit den freien Enden der aus dem Rohr e und der Stange h gebildeten Spreize mittels Kugelgelenken verbunden. Zu diesem Zweck enden e und h in je eine Lagerschalet, welche die mittels des Halses ν an der Druckplatte g angefügte Kugel u aufnimmt und durch zwei aufgeschraubte Halbringscheiben w abgeschlossen ist. Die Klemmflächen der Anpreßplatten g sind in der aus der Zeichnung ersichtlichen Weise gerieft, um an den Innenflächen des Mauerwerks r einen festen Halt zu gewinnen.
The invention aims at a further development of the lifting device intended for building purposes according to patent 369652, in which the cable pulley carrier is seated on a cross brace which is adjustable in length and which is inserted into a masonry opening. This device should now also be able to be spread firmly and immovably between inclined inner surfaces of the masonry. According to the invention, pressure plates are attached to the ends of the adjustable cross brace for pressing against the masonry walls by means of ball joints, the latter allowing the pressure plates to be adapted to the slope of the walls, so that the device is in its respective position by the spreading pressure without further aids is being held. The drawing illustrates a device embodied in accordance with the invention ao in Fig. 1 in plan view,
in Fig. 2 in front view;
Fig. 3 shows the ends of the spreader in section. As with the subject matter of the main patent, the support δ of the pulley a, supported by the supports q on the lower wall surface s, is attached to the tube e , in which the rod h is mounted and lockable by means of a clamping device k. According to the invention, the pressure plates g are connected to the free ends of the spreader formed from the tube e and the rod h by means of ball joints. For this purpose, e and h each end in a bearing shell t, which receives the ball u attached to the pressure plate g by means of the neck ν and is closed off by two half-ring disks w screwed on. The clamping surfaces of the pressure plates g are grooved in the manner shown in the drawing in order to gain a firm hold on the inner surfaces of the masonry r.

Soll die beschriebene Vorrichtung zwischen schrägen Innenflächen des Mauerwerks r eingespreizt werden, so kann die Lage der Anpreßplatten g mittels der Kugelgelenke u-t sehr leicht und genau der Schräge der Mauerflächen angepaßt werden, ohne daß es einer besonderen Anordnung oder Einstellung der Spreize e-h bedarf, und die Feststellung der Kugellager in der eingestellten Lage erfolgt ohne weiteres durch den Spreizdruck des in der Mauerwerksöffnung eingespreizten Gerätes. Wird zur Entfernung der Vorrichtung aus der Gebrauchslage, wie beim Hauptpatent, nach Lösung der Klemmvorrichtung k die Stange h in das Rohr e etwas hineingeschoben, so kommen infolge Aufhörens des Spreizdruckes die Kugelgelenke wieder aus ihrer Klemmlage, und die Druckplatteng· können von den Mauerflächen abgenommen werden.If the device described is to be spread between inclined inner surfaces of the masonry r , the position of the pressure plates g can be adapted very easily and precisely to the incline of the wall surfaces by means of the ball joints ut , without a special arrangement or setting of the spreader being required anyway , and the The ball bearings are fixed in the set position by the spreading pressure of the device spread in the masonry opening. If, in order to remove the device from the position of use, as in the main patent, after the clamping device k has been released, the rod h is pushed slightly into the tube e , the ball joints come out of their clamping position again as a result of the expansion pressure ceasing, and the pressure plates can be removed from the wall surfaces will.

Die Erfindung ermöglicht ein unverrückbar festes Einspreizen der Vorrichtung in die Mauerwerksöffnung bei jeder praktisch in Betracht kommenden Schräge der Anpreßflächen, ohne daß eine besondere Vorkehrung oder Handhabung bei der Anbringung des Gerätes erforderlich ist, und ohne daß ein besonderes Hilfsmittel (z. B. Werkzeug) angewendet zu werden braucht.The invention enables an immovable fixed spreading of the device in the Masonry opening at every practically possible incline of the contact surfaces, without any special precaution or handling required when attaching the device and without using a special aid (e.g. tool) needs.
