\ achse beweglich geführte Gerätestütze, insbesondere für \ axis movably guided device support, especially for
Projektoren.Projectors.
' ■'■
■' Es sind bereits verschiedene Arten verstellbarer Gerätestützen bekannt, die alle in der Herstellung mehr oder weniger aufwendig und verhältnismäßig umständlich zu bedienen sind. Meist sind mehrere, zusätzliche Handgriffe, wie beispielsweise das Herausdrehen einer»· Gewindespindel und .ihr Festklemmen, erforderlich.Various types of adjustable device supports are already known, all of which are more or less in the production are less expensive and relatively cumbersome to use. Usually there are several additional handles, such as unscrewing a »· threaded spindle and. their clamping, required.
Aufgabe der Neuerung ist es, eine Gerätestütze zu schaffen, die einfach herzustellen und zu handhaben ist und trotzdem funktionssicher arbeitet.The task of the innovation is to create a device support that is easy to manufacture and handle and still works reliably.
Gemäß der Neuerung arbeitet die Stütze mit selbsthemmenden Klemraitteln zusammen, die unter der Wirkung einer aufhebbaren Kraft, z.B. einer Federkraft, stehen.According to the innovation, the support works together with self-locking clamping means that can be lifted under the action of a Force, e.g. a spring force.
Wird die Federkraft aufgehoben, so kann die Gerätestütze auf Grund ihres Eigengewichtes aus dem Projektorgehäuse sich herausbewegen, bis die gewünschte Neigung des Projektors erreicht ist bzw. bis ein Anschlag wirksam wird, der das gänzliche Herausfallen vermeidet. Ein AnschlagIf the spring force is canceled, the device support can out of the projector housing due to its own weight move out until the desired inclination of the projector is reached or until a stop takes effect, which avoids falling out completely. An attack

Die Einstellung des Projektors kann aber auch so erfolgen, daß, ausgehend von dem längsten Auszug der Stütze, unter vorübergehender Aufhebung der auf die Kiemmittel wirkenden Federkraft der Projektor auf Grund seines Eigengewichtes sich in die erforderliche Stellung geneigt hat.The setting of the projector can also be done so that, starting from the longest extension of the support, under temporary suspension of the spring force acting on the gill means of the projector due to its own weight has leaned into the required position.
Die Gerätestütze wird zweckmäßig mit einer Feder verbunden, die sich im Gerätegehäuse abstützt. Wird eine Druckfeder benutzt, so ist dafür gesorgt, daß die Stütze beim Aufheben der Selbsthemmung aus dem Projektor heraustritt; bei Verwendung einer Zugfeder tritt der umgekehrte Fall ein.The device support is expediently connected to a spring which is supported in the device housing. Becomes a compression spring is used, it is ensured that the support comes out of the projector when the self-locking is released; Using the reverse case occurs with a tension spring.
Weitere Merkmale der Neuerung .sind den Unteransprüchen und der nachfolgenden Beschreibung zu entnehmen.Further features of the innovation are the subclaims and can be found in the following description.

Ira Ausfiihrungsbeispxel nach den Fign. 1 und 2 sind in einem Projektor 1 mi't einem Objektiv 2 ein Lager 3 und eine Lagerplatte 4 untergebracht. Die Lagerplatte 4 ist dabei durch Schrauben 5 und 6 am Projektor 1 befestigt. Das Lager 3 wird vom Projektorgehäuse getragen. Die Lagerplatte 4 trägt eine Klemmfeder 7 mit einem Durchbruch 8, dessen gegenüberliegende Flächen 9 und 10 keilförmig ausgebildet sind. Die aus dem Projektor 1 herausragenden Enden 11 und 12 der Klemmfeder 7 bzw. der Lagerplatte 4 sind als Griffelemente ausgebildet. Eine Gerätestütze 13 ist in der Bohrung 14 der Lagerplatte 4 und dem Lager 3 im Projektor 1 geführt und tritt zwischen beiden Lagerstellen durch den Durchbruch 8 in der KlemmfederIra execution example according to FIGS. 1 and 2 are in a projector 1 with a lens 2, a bearing 3 and a bearing plate 4 housed. The bearing plate 4 is attached to the projector 1 by screws 5 and 6. The camp 3 will carried by the projector body. The bearing plate 4 carries a Clamping spring 7 with an opening 8, the opposite surfaces 9 and 10 of which are wedge-shaped. The ones from the Projector 1 protruding ends 11 and 12 of the clamping spring 7 or the bearing plate 4 are designed as grip elements. A device support 13 is in the bore 14 of the bearing plate 4 and the bearing 3 guided in the projector 1 and occurs between the two bearing points through the opening 8 in the clamping spring
Im Ruhezustand legt sich die Klemmfeder 7 mit ihren keilförmigen Flächen 9 und 10 im Durchbruch 8 an die .Gerätestütze 13« Hierdurch tritt in Einschubrichtung der Gerätestütze 13 eine Klemmung auf, die die Gerätestütze 13 selbsthemmend festhält.In the idle state, the clamping spring 7 lies with its wedge-shaped surfaces 9 and 10 in the opening 8 on the device support 13 «This moves the device support in the direction of insertion 13 a clamp on which the device support 13 is self-locking holds on.
Zwecks Einstellung der gewünschten Stützhöhe werden die Griffelemente 11 und 12 gegeneinandergedrückt. Die Gerätestütze 13 ist auf diese Weise freigegeben und kann durch ihr Eigengewicht aus dem Projektorgehäuse 1 heraus bis zur Auflagefläche des jeweiligen Untersatzes gleiten. Je nachdem, in welcher Höhe über dem Untersatz der Projektor 1 durch Anheben am Griffelement 12 der Lagerplatte 4 gehalten wird, stellt sich die entsprechende Stützlänge ein. Durch Loslassen des Griffelementes 11 kann dann die gewünschte Einstellung fixiert werden.In order to set the desired support height, the grip elements 11 and 12 are pressed against each other. The device support 13 is released in this way and can through her Slide its own weight out of the projector housing 1 to the support surface of the respective pedestal. Depending on, the height at which the projector 1 is held above the base by lifting it on the handle element 12 of the bearing plate 4, the corresponding support length is set. The desired setting can then be made by letting go of the grip element 11 be fixed.
Im Au'sführungsbeispiel nach den Fign. 3 und 4 ist an Stelle der Klemmfeder 7 ein Klemmhebel 15 verwendet. Dieser Klemmhebel 15 lagert mit Zapfen 16 und 17 schwenkbar im Projektor Der von der Gerätestütze 13 abgewendete.Hebelarm des Klemmhebels 15 besitzt ein größeres Gewicht als der Teil, der die Gerätestütze 13 mit einem Durchbruch 18 umschließt. Wie im Falle der Klemmfeder 7 ist auch hier der aus dem Projektorgehäuse herausragende Teil des Klemmhebels 15 als Griffelement 19 ausgebildet. In Ruhestellung der Vorrichtung legt sich die Kante 20 des Durchbruchs 18 an die Gerätestütze 13 an. Der Abstand der Drehachse 16 und 17 von der Gerätestütze 13 und der Abstand der Drehachse von der Kante 20 des Durchbruchs 18 sind dabei so bemessen, daß die gewünschte Klemmwirkung eintritt.In the exemplary embodiment according to FIGS. 3 and 4 is in place the clamping spring 7, a clamping lever 15 is used. This clamping lever 15 is mounted pivotably in the projector with pins 16 and 17 The lever arm of the clamping lever facing away from the device support 13 15 has a greater weight than the part which encloses the device support 13 with an opening 18. Like in The case of the clamping spring 7 is also here the part of the clamping lever 15 protruding from the projector housing as a grip element 19 trained. When the device is in the rest position, the edge 20 of the opening 18 lies against the device support 13 at. The distance between the axis of rotation 16 and 17 from the device support 13 and the distance between the axis of rotation and the edge 20 of the opening 18 are dimensioned so that the desired clamping effect occurs.
Wie im vorhergehend beschriebenen Ausführungsbeispiel werden zwecks Verstellung der Stützhöhe die sich gegenüberliegenden Griffelemente 12 und 19 erfaßt und gegeneinandergedrückt. Dabei gibt allein der Klemmhebel 15 nach. Die Klemmung ist gelöst. Nachdem die gewünschte Stützhöhe wiederum durch Anheben der Lagerplatte 4 am Griffelement 12 eingestellt ist, wird das Griffelement 19 und damit der Klemmhebel 15 losgelassen, der durch das Eigengewicht des Hebelarmes 15 sofort in die Klemmstellung zurückkehrt.As in the previously described embodiment, the opposite sides are used to adjust the support height Gripping elements 12 and 19 detected and pressed against each other. Included only the clamping lever 15 yields. The clamp is released. After the desired support height has again been set by lifting the bearing plate 4 on the handle element 12, the grip element 19 and thus the clamping lever 15 released, which immediately returns to the clamping position due to the weight of the lever arm 15.
In beiden Ausführungsbeispielen bewirkt das Gerätegewicht beim Aufsetzen auf die Stütze 13 ein sicheres Verkeilen der selbsthemmenden Klemmvorrichtung.In both embodiments, the device weight causes when placed on the support 13 a secure wedging of the self-locking clamping device.
