Description

  

  W     echselstr        omwecker.       Den Gegenstand vorliegender Erfindung  bildet ein     Wechselstromwecker,    welcher eine  Glockenschale aufweist, welche mittelst einer  Feder derart über     einem    feststehenden     Wech-          seIstromelektromagneten    befestigt ist, dass  dieselbe infolge des     Nagnetwechselfeldes    in  Schwingungen gerät und auf einen Anschlag  aufschlägt.  



  In der beiliegenden Zeichnung ist ein  Ausführungsbeispiel des Erfindungsgegen  standes dargestellt. Es zeigt:       Fig.    1 einen     Querschnitt    durch den  Wecken       Fig.        =    eine Draufsicht des Weckers ohne  Glockenschale.  



       F'ig.    3 die Federbefestigung der Glocken  schale in grösserem Massstab.  



  Auf einem runden Sockel 1 aus elektrisch  isolierendem Material, ist ein     Magnetkern    5  mit der     Erregerwicklung    3 befestigt. Die aus  einem     magnetisierbaren    Metall bestehende  Glockenschale 2 ist     mittelst    einer Stahlband  feder 7 und einer     Eisenschraube    G so mit dem  Kern 5 verbunden, dass bei 4     zwischen    Mag-         net    und Glockenschale ein     Luftspalt    besteht.  Zur     Befestigung    der Glockenschale 2 an der  Feder 7 ist eine Hohlniete 8 vorgesehen.

    Ausserdem trägt der Sockel 1 einen, als, An  schlag für den Rand der     Glockenschale    2  dienenden Knopf 11. Klemmen 9 und 10  dienen zur     Stromzuführung    zur Erregerwick  lung 3.  



  Wird der Wecker     mittelst    der     Klemmen     9 und 10 in einen     Wechselstromkreis        einze-          schaltet,    so,     wird,der    Kern 5     magnetisiert    und  zieht die Glockenschale 2 an. Zufolge ,der  Erregung des Kernes durch Wechselstrom  und der Befestigung der Glockenschale 2  auf einer Feder 7, gerät dabei die Schale 2       in,        Schwingungen    entsprechend der     Frequenz     .des Wechselstromnetzes, an welches der     Wek-          ker        angeschlossen    ist.

   Der Rand der Schale  2 trifft dabei auf den als Anschlag dienen  den Knopf 11 auf und die Glocke ertönt.  



  Die     Glockenschale    2. könnte auch aus       nichtmagnetisierbarem    Material bestehen, in  welchem     Falle,das    Anziehen derselben ,durch  die Einwirkung des     Magnetes    auf die in     vier         Glockenschale 2 eingelassene Hohlniete  erfolgt. Die     Letztere    müsste dabei naturge  mäss aus     magnetisierbärem    Material bestehen.



  Alternating current alarm clock. The subject matter of the present invention is an alternating current alarm clock which has a bell shell which is fastened by means of a spring above a stationary alternating current electromagnet in such a way that it vibrates as a result of the alternating magnetic field and strikes a stop.



  In the accompanying drawing, an embodiment of the subject invention is shown. It shows: FIG. 1 a cross section through the alarm clock; FIG. 1 a plan view of the alarm clock without a bell shell.



       F'ig. 3 the spring fastening of the bell bowl on a larger scale.



  A magnetic core 5 with the excitation winding 3 is attached to a round base 1 made of electrically insulating material. The bell shell 2, which consists of a magnetizable metal, is connected to the core 5 by means of a steel band spring 7 and an iron screw G in such a way that at 4 there is an air gap between the magnet and the bell shell. A hollow rivet 8 is provided for fastening the bell shell 2 to the spring 7.

    In addition, the base 1 carries a button 11 that serves as a stop for the edge of the bell shell 2. Terminals 9 and 10 are used to supply power to the exciter winding 3.



  If the alarm clock is switched on by means of the terminals 9 and 10 in an alternating current circuit, the core 5 is magnetized and attracts the bell shell 2. As a result of the excitation of the core by alternating current and the fastening of the bell cup 2 on a spring 7, the cup 2 starts to vibrate according to the frequency of the alternating current network to which the clock is connected.

   The edge of the shell 2 meets the button 11 as a stop and the bell sounds.



  The bell shell 2 could also consist of non-magnetizable material, in which case the attraction of the same takes place through the action of the magnet on the hollow rivets embedded in four bell shell 2. The latter would naturally have to consist of magnetizable material.
