  Elektrisch heizbare Decke. 



   Vorliegende Erfindung bezieht sich auf   ele1. -trisch heizbare   Decken, insbesondere für therapeutische Zwecke, und besteht darin, dass der Heizwiderstand spiralförmig angeordnet ist und die   Stromzuführung   durch eine in die Mitte desselben führende Leitung erfolgt, während die an dem Rande gelegenen   Windungen   mit in   Kontaktstellen endigenden Abzweigungen zwecks   Änderung der Widerstandslänge bzw. der Temperatur versehen sind, so dass der zentrale Teil des Widerstandes   immer   auf der der Widerstandslänge entsprechenden   Temperatur     gleichmässig   erwärmt gehalten wird. 



   In der Zeichnung ist in Fig. 1 die Anordnung des Widerstandes in beispielsweiser Ausführungsform veranschaulicht, während die Fig. 2,3 und 4 Einzelheiten zeigen. 



   Der Widerstand   4   ist auf einer Unterlage von Asbest oder dgl. in   spiralförmigen     Windungen   befestigt und zwischen jeder Windung eine isolierende Schnur j aus Asbest oder dgl. angeordnet.

  Electrically heated ceiling.



   The present invention relates to ele1. -trisch heatable blankets, especially for therapeutic purposes, and consists in the fact that the heating resistor is arranged in a spiral and the power is supplied through a line leading into the middle of the same, while the turns located on the edge with branches ending in contact points for the purpose of changing the resistance length or the temperature so that the central part of the resistor is always kept evenly heated to the temperature corresponding to the length of the resistor.



   In the drawing, the arrangement of the resistor is illustrated in an exemplary embodiment in FIG. 1, while FIGS. 2, 3 and 4 show details.



   The resistor 4 is attached to a base made of asbestos or the like in spiral turns and an insulating cord j made of asbestos or the like is arranged between each turn.
 EMI1.1
 that only the outermost turns are switched off and the central part of the resistor is kept constant at the temperature corresponding to the length of the resistor

Claims

The contact is expediently made by a pincer-like terminal 14 made of insulating material, which is held in the closed position by a spring 15 and a metal button 16 is provided on the inner sides, which is in conductive connection with one cable 1 EMI1.3 <Desc / Clms Page number 2> EMI2.1

2. Connection line for the electric heating blanket according to claim 1, characterized in that the two power supply cords (17, 171) have different lengths and the sleeve-like part (20) of the plug contact (19, 20) making the connection to the line (6) ) is arranged within a sleeve (18) made of insulating material, for the purpose of touching EMI2.2 thus avoiding a short circuit.

3. For the electric blanket according to claim 1, a pincer-like contact clamp made of insulating material for the contact points (9), characterized in that the same is obtained in the closed position by a spring (15) or the like and one with the longer on the inside Power supply cord (17) connected contact button (16) which can be clamped to one of the contact points (9).
