Die Zeichnung veranschaulicht ein Keilkissen, welches von der darauf liegenden Person nach Bedarf in der Schräglage eingestellt werden kann.The drawing illustrates a wedge pillow, which is followed by the person lying on it Can be adjusted in the inclined position as required.
Fig. ι zeigt die Vorderansicht desselben, Fig. 2 den Grundrifs, Fig. 3 eine Seitenansicht bei herabgedrücktem Kissen und Fig. 4 eine Seitenansicht mit hochstehendem Kissen.Fig. 1 shows the front view of the same, Fig. 2 shows the outline, Fig. 3 shows a side view with the cushion pressed down and FIG. 4 a side view with the cushion upright.
Das Keilkissen besteht aus einem Rahmen A, welcher auf die Lagerflä'che aufgelegt wird. Mit dem Rahmen A ist im Drehpunkt χ ein zweiter Rahmen B und die als Geflecht, Netz oder derartig gebildete Kissenlagerfläche C drehbar verbunden, welch letztere wiederum, um ihr eine gewisse Elasticität zu verleihen, mittels federnder Bolzen α mit dem Rahmen B verbunden ist.The wedge cushion consists of a frame A, which is placed on the bearing surface. A second frame B is rotatably connected to the frame A at the pivot point χ and the cushion bearing surface C, formed as a mesh, net or such, which in turn, in order to give it a certain elasticity, is connected to the frame B by means of resilient bolts α.
Zur Erreichung der Selbsteinstellung ist ferner der Rahmen A mit dem Rahmen B durch eine aus den Theilen b und d bestehende Gelenkschiene verbunden, die ihre Drehpunkte in wy und \ hat; aufserdem trägt die Gelenkschiene b den Einlegzapfen u, welcher in den Zahnbogen f eingreift.To achieve self-adjustment, the frame A is also connected to the frame B by a hinge rail consisting of parts b and d , which has its pivot points in wy and \ ; In addition, the hinge splint b carries the insertion pin u, which engages in the dental arch f.
Dieser wird vom Handhebel D mittels der Zwischenschiene g bewegt und kann ersterer auf Zug oder Druck von der Lagerstelle aus eingerichtet sein, wie das die vollausgezogene und die punktirt gezeichnete Stellung in Fig. 2 andeutet.This is moved by the hand lever D by means of the intermediate rail g and the former can be set up to pull or push from the bearing point, as the fully extended position and the dotted position in FIG. 2 indicate.
Der Zahnbogen ist bei ν am Rahmen A drehbar befestigt und wird von der Feder h nach abwärts gedrückt, während die Federn k die Rahmen A und B aus einander spannen.The dental arch is rotatably attached to frame A at ν and is pressed downwards by spring h , while springs k tension frames A and B apart.
Es hängt somit B C in den Punkten xvuw an A fest und eine Verstellung von C ist möglich, wenn u im Zahnbogen f gelüftet, sowie C und f durch Druck auf C und durch den Hebel D nach Belieben eingestellt werden; ferner kann u im Zahnbogen f nach Freilassen von D durch den Druck der Feder h wieder in u festgestellt werden. BC is thus stuck to A at points xvuw and an adjustment of C is possible if u is lifted in the dental arch f , and C and f can be adjusted as desired by pressing on C and using the lever D; Further, in the dental arch u f after releasing of D by the pressure of the spring h again and observed.
