Gegenstand der Erfindung ist eine Reklamevorrichtung mit absatzweise laufendem Elektromotor, der mit einem von ihm aufzuziehenden und zum öffnen und Schließen des Stromkreises dienenden Federmotor durch ein das Überspannen der Feder verhinderndes Schnurtrieb verbunden ist. Erfindungsgemäß sind zur rechtzeitigen Ausschaltung des Elektromotors an den Bandhemmungen Nebenkontakte angeordnet, die in dem Augenblick abgeschaltet werden, wo die Einrückung der Bandhemmungen beginnt. Auf diese Weise wird eine Beschädigung der Hemmvorrichtung durch Weiterlauf des Elektromotors verhütet und der zum öffnen und Schließen des Stromkreises dienende Federmotor ergänzt.The subject of the invention is an advertising device with an intermittently running electric motor, the one with one to be wound up by him and to open and close the circuit serving spring motor by a cord drive preventing over-tensioning of the spring connected is. According to the invention are to timely shutdown of the electric motor Secondary contacts arranged on the tape escapements, which are switched off at the moment where the engagement of the escapement begins. This will damage the jamming device prevented by keeping the electric motor running and opening and closing the circuit serving spring motor added.

Die Kurbelstange 26 dient zum Antrieb des Zahnsegmentes 25, das die endlosen Reklamebänder i, 2 bzw. deren Walzen 3, 9 mittels des Rädergetriebes 29 bis 33 in Bewegung setzt (Fig. 1). Die Kurbelstange 26 ist grob und fein einstellbar, grob mit Hilfe der Löcher 27 an der Kurbel 23 und fein am Zahnsegment 25 mittels der Löcher 28 (Fig. 1). Die Daumenscheibe 24 der Welle 20 setzt mittels der Hebel 47, 48, 49 eine Hemmvorrichtung in Tätigkeit, die aus den unbeweglichen Leisten 41, 42 und den beweglichen Leisten oder Bügeln 43, 44 besteht (Fig. 1 und 2). Die Bügel 43, 44 stehen unter dem Einfluß von Federn 45, 46 und werden der Wirkung dieser Federn entgegen in bestimmten Zeitabständen gegen die endlosen Bänder 1 und 2 gedrückt. Diese kommen dabei gegen die festen Leisten 41, 42 zu liegen, so daß die Stäbe 50 auf der Rückseite der Bänder an den Leisten 41, 42 nicht vorbeigehen können. Beim Einschalten der Bandhemmung wird ein einstellbarer Kontakt 86¹, 87¹ stromlos, der an dem Bügel 44 sitzt und im Motorstromkreis liegt.transmission i8, 19 to the shaft 20, which carries at one end a pulley 21 for automatic winding of the spring motor and at the other end a thumb washer 24 and a crank 23 (Fig. 1 and 2). The connecting rod 26 serves to drive the toothed segment 25, which sets the endless advertising tapes i, 2 or their rollers 3, 9 in motion by means of the gear train 29 to 33 (FIG. 1). The connecting rod 26 is roughly and finely adjustable, roughly with the help of the holes 27 on the crank 23 and finely with the toothed segment 25 by means of the holes 28 (FIG. 1). The thumb disk 24 of the shaft 20 uses the levers 47, 48, 49 to activate a locking device which consists of the immovable strips 41, 42 and the movable strips or brackets 43, 44 (FIGS. 1 and 2). The brackets 43, 44 are under the influence of springs 45, 46 and are pressed against the action of these springs against the endless belts 1 and 2 at certain time intervals. These come to rest against the fixed strips 41, 42, so that the bars 50 on the back of the belts cannot pass the strips 41, 42. When the tape lock is switched on, an adjustable contact 86 ¹ , 87 ¹ , which sits on the bracket 44 and is in the motor circuit, is de-energized.

moderately consisting of an endless helical spring 88 cord drive on the pulley 63 of a shaft 56 of the current closer 22 of the electric motor. On the shaft 56 sits according to Fig. 2 and 3, a toothed washer 57, which for Spring motor belongs and is provided with any number of stops 59 near the edge.

At 72, 73 two levers 70, 71 are freely suspended on the housing 52 of the device 22, of which 70 usually by a spring 74 against the housing and 71 by a Spring 75 is pulled against a stop 76 on the housing (Fig. 4). The two levers represent the circuit breaker for the electric motor 17 and contribute to this purpose insulates the contacts 82, 83, which are expediently made of silver or platinum. The lever 70 is provided with a stop surface 84 which is in the path of the stops 59 of the wheel 57 is so that the lever 70 rotated each time such a stop is encountered and contacts 82, 83 are closed. The oscillation amplitude depends on the adjusting screw 85, which determines the distance determined between 71 and 76.

After the spring housing 58 has first been opened a little by hand, the wheel 57 starts moving. As soon as one of the stops 59 hits the stop surface 84, the lever 70 oscillates against the lever 71 and thus the contact closes at 82, 83. The motor circuit is now closed, since the contact 86 ¹ , 87 ¹ on the belt escapement is also switched on . The electric motor 17, which starts up as a result, pulls the spring motor 58 up by means of the helical spring 88 without fear of overstressing it, and at the same time brings the stop 59, which had been in effect for some time, out of the area of the lever 70 until it springs back and the contacts 82, 83 can switch off again, ie opens the motor circuit. The spring motor starts moving again, and the game repeats itself after every current surge that the electric motor experiences.

When the electric motor 17 switches the bands 1, 2 on, the thumb 24 assumes such a position that the springs 45, 46 hold the bracket 43, 44 of the inhibiting device in the position shown in FIG. Finally, however, as soon as the bands 1, 2 are moved further by the height of a display or announcement, the thumb 24 rotates the lever 47, whereby the brackets 43, 44 are rotated inwards counter to the springs 45, 46, with the effect that the stop bars 41, 42 get into the path of the inhibiting bars 50 of the bands. At the moment the jamming bar 43, 44 are turned inwards, the secondary contact 86 ¹ , 87 ^{1 is} opened and the motor circuit is thus interrupted, completely independently of the current interruption in the device 22. The spring motor actually only provides the power supply, while the secondary contact 86 \ 87 ^l causes the electric motor to switch off in good time.

The invention can be modified in various ways. For example, the other jamming bars 43. wear a contact device.
