Description

Den Gegenstand der Erfindung bildet eine Klemmvorrichtung für die schwenkbaren Tragarme von Lampen ■ und anderen - Gegenständen, deren Stellung verändert werden soll. Das Wesen der Erfindung besteht darin, daß der den Gebrauchsgegenstand tragende Hebelarm mit zwei Führungszapfen ausgerüstet ist, die beiderseits in Führungskurveri eingreifen. Diese Leitkurven sind in Platten ίο eingeschnitten oder eingedrückt, die in einem Lager, z. B. eines Lampenfußes, untergebracht sind.The subject of the invention forms a clamping device for the pivotable Support arms of lamps ■ and other objects whose position is changed target. The essence of the invention is that the wearer of the commodity Lever arm is equipped with two guide pins, which are in guide curves on both sides intervention. These guide curves are cut or indented into plates ίο that are in one Warehouse, e.g. B. a lamp base are housed.

Auf der Zeichnung sind einige Ausführungsformen der Erfindung zur Darstellung '5 gebracht, und zwar zeigen:Some embodiments of the invention are shown in the drawing '5, namely show:

Abb. ι und 2 eine Ausführungsform im Längsschnitt bzw. Querschnitt,Fig. Ι and 2 an embodiment in longitudinal section or cross section,

Abb. 3 und 4 eine zweite Ausführungsform im Querschnitt bzw. in Ansicht und
Abb. 5 in verkleinertem Maßstabe eine Lampe mit Klemmvorrichtung.Fig. 3 and 4 a second embodiment in cross section and in view and
Fig. 5 shows, on a reduced scale, a lamp with a clamping device.

Es bezeichnet α den den Gebrauchsgegenstand tragenden Hebelarm, der am Ende gekrümmt ist und mit zwei Führungszapfen Z'1, ^2 versehen ist, welche sich in Nuten von Klemmschalen c führen. Die Klemmschalen sind durch einen Schraubenbolzen d mit dem Gestell / verbunden, das beispielsweise als Lampengestell ausgebildet ist (Abb. 5).It denotes α the lever arm carrying the commodity, which is curved at the end and is provided with two guide pins Z ' 1 , ^ 2 , which are guided in grooves of clamping shells c . The clamping shells are connected to the frame / by a screw bolt d , which is designed as a lamp frame, for example (Fig. 5).

Das eine Ende des Schraubenbolzens d ist in einer Platte e eingeschraubt, die sich über den Umfang der Klemmschale c erstreckt und für dieses ein Widerlager bildet.
Die Wirkungsweise ist folgende:One end of the screw bolt d is screwed into a plate e which extends over the circumference of the clamping shell c and forms an abutment for this.
The mode of action is as follows:

Wird der Hebelarm a1 nach abwärts gedreht, so daß er in die Stellung a„ gelangt, dann pressen sich die Führungszapfen b1, b2 in Richtung des Pfeiles s1 gegen den Rand der Klemmschale. Gleichzeitig wird die Klemmschale durch geringes Verdrehen des Schraubenbolzens d etwas gegen die Klemmplatte c gepreßt und· dadurch eine erhöhte Klemmwirkung erzielt. Beim Zurückdrehen in Richtung der Pfeile 2 tritt eine geringe Entlastung ein. jedoch bleibt eine Klemmwirkung immer noch in Kraft.If the lever arm a 1 is rotated downwards so that it reaches the position a ", the guide pins b 1 , b 2 are pressed in the direction of the arrow s 1 against the edge of the clamping shell. At the same time, the clamping shell is pressed somewhat against the clamping plate c by slightly turning the screw bolt d, thereby achieving an increased clamping effect. When turning back in the direction of arrows 2 , a slight relief occurs. however, a clamping action still remains in place.

Man kann die Einrichtung auch so treffen, daß an Stelle eines Hebelarmes α zwei Hebelarme vorgesehen sind, wovon jeder mit zwei exzentrisch zu dem Schraubenbolzen d sitzenden Führungszapfen ausgerüstet ist. Die Einrichtung kann auch so getroffen sein, daß die Führungsnut c der Klemmschalen eine ι geschlossenen Kurvenzug ergibt (Abb. 3).The device can also be designed in such a way that, instead of a lever arm α, two lever arms are provided, each of which is equipped with two guide pins seated eccentrically to the screw bolt d. The device can also be made so that the guide groove c of the clamping shells results in a ι closed curve (Fig. 3).
