The alarm clock shown in Figure 1 consists, strictly speaking, of a clock part G and a radio part R- As can be seen in FIGS being held. On the board 22 an alternating Lrom synchronous motor 25 is attached, the shaft of which has a pinion 26 which meshes with a set of reduction gears 27 and 2Ü. The fourth wheel 30 is driven by these. The latter is connected to a shaft 31, at the front end of which the second hand 32 is attached. The second wheel 30 carries a pinion 33 »which meshes with a reduction gear 34 with a pinion 35. The pinion 35 is rotatable with respect to the gear 34, but is driven by this by a ratchet

taken, which is shown in Figure 4a. This Bastgesperre consists of a star wheel 36 in a fixed connection with the pinion 35 and three claws 37 »which are attached to the Set 3Ö are attached to the gear 34 that their free ends 39 engage resiliently in the star wheel 36. The parts of this locking mechanism can be made of plastic, which is responsible for the normal drive transmission a sufficient torque is allowed, but easily overcome with manual adjustment of the clock hands of the intervention.

A minute wheel 40 "meshes with the pinion 35, which is connected to a shaft 41 supporting the minute hand 42. Furthermore, a pinion 43 on the minute wheel, which is converted into a reduction gear 44 with a pinion 45 engages, an hour wheel 50 with a translation of '■ 2-1' · is driven with respect to the minute wheel. The hour wheel sits on a forwardly protruding shaft 51, which the hour hand 52 carries.

To trigger the alarm, the hour wheel 50 is slidably mounted in the axial direction and has cams 53 on its end face. Coaxially with and following the hour wheel, a Wekice rs part wheel 60 with a hollow shaft 61 which carries a pointer 62 is provided. The adjusting wheel 60 carries a corresponding set of cams 63, which are opposite the cams 53. Suffice it to say, referring to FIG. 7, that the cams 53 and 63 slide on each other at a predetermined jerk time, the axial displacement of the hour wheel ti 50 caused thereby causing the triggering of the alarm via the Mibbol described below. To change the angular position of the WookerateTLrades to itüwiim, iub a {Heliwollö G ^s j inLb ein

Projection 66 is provided, the axial displacement of the Shaft 65 to the rear with a slot 67 within an adjusting pinion 6Ö (Figure 3) comes into engagement. That Pinion 6Ö is used to rotate the adjusting wheel 60 with which the cams 63 as well as the pointer 02 into a new / inclined position to be brought.

In order to set the clock hands, the pinion 35 in connection with the gear 34 is also provided with a slot 69, into which the projection 66 engages as the shaft h 65 is withdrawn. The locking mechanism is overcome, so that the gear parts lying between the star wheel 36 and the motor are not moved along with it.

Furthermore, a selector spindle 70 is now provided which carries a selector lever ü'O (.Figuren 4, 5 and b). By Spring force normally holds the selector spindle 70 in an intermediate of three positions, i.e. as long as it is is not held by stops in one of the two outer Siellungen from which it is due to the axial movement of the v / ahlhebels can be released. With the selector spindle 70 is a switch connected, which is then closed when * the dial spindle the so-called setting in the middle occupies. The Wüiilhebel 60 is formed so that ei ·, it is read manually into the au t oma ti by the dial spindle ellt gouracht, a I put 50 in front of the hour wheel, whereby it is shifted by the hour wheel at the set time and thus it has so far been in the automatic position hai tendon stop left to Ln the on position return, with or a circuit for the associated Radio part uohiLasst. Specifically, the selection spindle 70 has a rotary knob Yl and white at its rear end oino flat 72, which is connected to oiner contact spring 73 in

Cooperates shape of a bent spring wire. This contact spring leans against the selector spindle, whereby they by acting on the edges 72a and 72b of the flattening endeavors, the selector spindle in its middle or setting to lead, in which the spring runs along the flat 72 and at a fixed contact 74 to Plant is coming.

As mentioned, a selector lever is on the selector spindle 70 8O attached. This has a stop pin on one side 83, the one with a stop 81 for the off position and a stop Ö2 for the automatic position on the neighboring Board 21 cooperates. Furthermore, a projection Ö4 is integrally formed on the selector lever 80 in the position, that it does not come into engagement with the hour wheel 50 as long as the selector lever is in the off position, however the hour wheel then gets in the way when the selector spindle with the selector lever is in the automatic position. The force for the resilient engagement and that of the axial displacement of the selector lever for releasing the stops counteracting restoring force is expediently achieved in that the selector lever, optionally in one piece together with the selector spindle, made of elastic plastic and made relatively thin in the axial direction will. As FIG. 5 shows, the selector spindle 70 is rotated counterclockwise into the off position according to this figure been, with the stop pin Ö3 behind the stop Ö1 is engaged. In this position, the contact spring 73 is lifted from the contact 74, so that the circuit of the radio part is interrupted. In order to put the radio into operation, the knob 71 must be turned, whereby the stop pin slides away while bending the selector lever over the stop 81.

The selector spindle is used for automatic operation, i.e. for turning on the radio at the set time

009842/1230 -. /.

guided beyond the on position into the automatic position, which is shown in FIG. The edge 72b of the flat 72 lifts the contact spring 73 from the contact 74, so that the electrical circuit of the radio is interrupted. The selector lever ÖO is held in the relevant position by engaging the stop pin Ö3 behind the stop 62. When the set time is reached, ie when the cams 53 of the hour wheel slide onto the cams 63 of the alarm setting wheel, which leads to an axial displacement of the projection 84 and thus a bending of the selector lever, a point is finally reached at which the stop pin 63 behind the Stop ö2 emerges (Figure 7). As a result, the selector spindle 70 is released in order to return under the influence of the contact spring 73 to its central position corresponding to the on position (FIG. 6), the contact spring coming into contact with the fixed contact 74. This completes the radio circuit that wakes the sleeper. If the latter wishes to switch off the radio, he turns the button 7 '; into the off position, the stop pin 03 of the selector lever engaging behind the stop ö " .

The clockwork described so far is still equipped with a so-called release lever 100, the one Wears claw and is subjected to the action of a spring which seeks to keep it out of engagement with the minute wheel 40, which, however, can be pivoted by hand in order to move the claw into a position that engages the teeth of the minute wheel bring what it initially slides over these teeth. A stop is provided on the release lever, which is connected to the Selector lever can intervene in order to inevitably lead it into the Aua position and thus the radio temporarily shut down. However, as the minute wheel continues to move, the claw with the release lever gradually becomes

009842/1230

led back to the disengagement division, ie _o within a period of about 10 minutes, which is the "doze time". Another stop on the release lever in the opposite direction, which comes into engagement with the selector lever when the claw is released from the minute wheel, serves da.3u to overcome the stop Ö1 for the off position, so that the selector lever is in the on - Return to position karu., In which he puts the radio back on. The release lever is essentially L-shaped, with the long leg providing an engagement surface for the actuation and the short leg carrying the claw and the stops, all of these parts being formed in a single piece of elastic plastic.

As can be seen from Figure 5, the release lever 100 is mounted on a pivot 101 and is supported by a tension spring 102 loaded, which seeks to lead it upwards against a stop 103. The long one that runs roughly horizontally Leg of the release lever crosses the path of a push button 104. At the free end of the short leg of the release lever there is the claw, 105, by one arm

106 reduced cross-section is worn. The claw lies in the same plane as minute wheel 40.

To move the selector lever into the off position, whereby the contact is interrupted, is a stop, as I said

107 is provided, which lies at the end of the long leg of the release lever ". Within the path of the stop 107 there is a stop 10Ö of the selector lever in the form of an axially extending pin molded onto it. If the push button 104 is depressed, as shown in FIG. while he swivels the release lever accordingly, the following then happens: the first thing to do is to slide the claw 105 over

009842/1230

- ΊΟ

the teeth of the minute wheel 40 away until it finally engages between two teeth, which need about 10 minutes to reach the release position. The locked position is determined by a fixed stop 109 which limits the pivoting movement of the release lever. Second, the stop 107 of the release lever comes into engagement with the stop 106 on the selector lever, with which the latter is pressed down to a position in which the stop pin 03 engages behind the stop oil corresponding to the off position. During the accompanying rotational movement of the selector spindle 70, the edge 72a of the flat area 72 causes the contact spring 73 to lift off the fixed contact 74, thus stopping the radio.

Furthermore, as mentioned, a stop 111 (FIGS. 9 and 10) is provided on the release lever, which is connected to the Stop 1ÜÖ of the selector lever comes into engagement to the the latter returned to the off position at the end of the "dozing time". The stop 111 is opposite the stop 107 arranged so that it is connected to the other side of the Stop 10b 'comes into engagement. During the time in which the pawl 105 is engaged with the minute wheel 40 fc stands, aie is indicated by the one taking place in the direction of the arrow in FIG Movement of the lvi Minutenrades upwards, with finally the stop 111 on the underside of the Stop 1üB comes to the plant. In the course of the further movement of the release lever, the stop 10Ö is used to lead the stop pin ti 3 over the stop Ö1 and to release the selector lever 00 so that it is in the off position under the influence of the contact spring 73 returns. At the same time, the contact spring 73 closes the circuit for da3 liadio. Almost at the same time leaves the Claw 105 daa minute wheel 40, whereupon the release lever under the influence of the spring 102 upwards into its starting position

- '11 jumps back (Figure 12).

It deserves to be emphasized that, although the stops 107 and 111 of the release lever at the beginning and At the end of the "doze time", the selector lever is used to interrupt or close the radio circuit is freely movable when the release lever is in the rest position, so that it is arbitrarily guided into any desired position can be. This is achieved by placing the selector lever and release lever at different points (selector spindle 70 and pivot pin 101) and that the stops 111 and 111 are arranged so that they are in their inactive position lie considerably outside the connecting line 112 of the two pivot points (FIG. 5). The attacks 107 and 111 have an inactive position in which they have the Do not hinder movement of the selector lever 80, so that it can easily be moved manually between its two extreme positions (Figures 5 and 6) can be back and forth. Tim these To further improve functional separation, the stop 111 preferably has a shorter effective radius from the axis of the pivot 101 than the stop 107. With this, the release lever 100 can be operated even when the selector lever 80 assumes the off position shown in FIG. As can be seen in FIG. 13, the stop is 10ö only grazed by the stop 111 of the latter during the downward movement of the release lever. For his To increase compliance is the cross-section of the short leg of the release lever at 106a as well as at 106 reduced, so that there are practically two adjoining elastic arms.

Just like the release lever and the selector lever with its spindle, so can the gears and most of the others Parts of the clockwork can be made of plastic. the

009842/1230

BATH ORIGINAL

For example, gears and levers can be made from a formaldehyde condensation product be molded as it is under the trade name "Celcon" or "Delrin" on the Market is coming. These plastics have an extremely high dimensional stability and wear resistance in combination with adequate strength and elasticity. To the contact surface of the stop 107 with the stop 10b is expediently to be increased at the release lever immediately next to the contact parts of the stop 107 Shaped pin 107a.

It will be apparent to those skilled in the art that certain changes can be made to the construction described so far while maintaining the functionality. Thus, for example, the link 100 (release lever) in the preceding illustration, which is referred to as a “lever” because of its pivotability, can easily be a translationally movable part. Likewise, for example, the “lever” dO (V / selector lever) can be constructed in several parts or even replaced by a unit consisting of several levers. The projection ö4 of the "selector lever" 8o, which is supposed to come into engagement axially with the hour wheel, may be omitted, namely if that section of the selector lever Ö0 which protrudes over the hour wheel 50 is omitted and instead the selector lever is closer in the axial direction the hour wheel is moved closer, although preference is given to the arrangement of the projection Ö4 together with the overlap of the selector lever, because this eliminates an otherwise possible mutual hindrance of the selector lever and the hour wheel. The "dozing time" can also be determined in a manner other than that shown here with the engagement of the claw 105 in the minute wheel 50, for example with the aid of any other suitable gear. The contact with which the electrical circuit of a radio is closed after the preceding can also be

009842/1230

control any other suitable electrical consumer or through some other element to trigger a Alarms to be replaced.

Although the operation of the clock described should have already become clear from the above illustration, it may be useful to recapitulate them again using FIGS. 5 to 12.

In simple operation, the individual parts assume the position shown in FIG. 5, with the selection spindle 70 was brought into the off position by hand, in'der it is held by the stop 81. In this position the radio circuit is interrupted.

To operate the clockwork as an alarm clock, the button 71 of the selector spindle 70 is manually in the automatic position rotated, in which the selector lever 80 is held by the stop 82 and the projection 84 in front the hour wheel 50 comes to rest. Once the set point in time has been reached (Figure 7) »the axial movement takes place of the hour wheel for bending the selector lever 80 in the axial direction, whereby the stop pin 83 behind the stop 82 emerges so that the selector lever under the action of the contact spring 73 in its central on position returns, at the same time the contact is closed and the radio starts playing.

If the awakened person wants silence for a further 10 minutes, then he presses the pushbutton 104 on top the housing and thereby swivels the release lever 100 down, with the claw 105 over the teeth of the minute wheel 40 is led away until it, when the Auesetzebel hangs on the stop 109, between two teeth for

009842/1230

Calm comes. The simultaneous engagement between the stop 107 of the release lever and the stop 106 of the selector lever 00 brings the latter down into the off position, in which the stop pin 03 of the selector lever engages behind the stop o1.

In the course of the subsequent time, the claw 105 of the release lever is guided upwards by the minute wheel, the stop 111 of the release lever now engages with the stop 10Ö (FIG. 10) and the selector lever leads to the on position. That through the minute wheel The torque transmitted to the release lever is sufficient to guide the stop pin Ö3 over the stop oil (Figure 11) so that the selector lever jumps into the on position (Figure 12) with the radio switched on again will. It goes without saying that the push button 104 can be actuated as often as desired, one additional at a time To achieve "dozing time" of, for example, 10 minutes.
