Patent application for alarm clock with electrical alarm signaling

The present invention has an electric drive alarm clock, electrical alarm signaling and electrical dial lighting to the subject.

The invention relates in particular to an electric alarm clock of the aforementioned type, in which the electrical signal is triggered by the axial displacement of the hour wheel depending on the position of the alarm clock wheel is effected » The invention pursues the purpose of creating an electrical alarm device which is characterized by spatially favorable dimensions and it allows, using a dry battery, a wake-up signal generator to give a wake-up signal of a certain duration every day certain preselectable time for many months to be reliably delivered. The invention is also intended to be a simple and safe intervention for manual time limitation of the wake-up signal can be created.

The invention also has the purpose for manual alarm signal limitation and to provide a single control element for switching on the dial lighting, whereby it is ensured that that a mutual impairment of the two operations is prevented and a simple and safe way to intervene manual time limitation of the wake-up signal is given.

109833/0920

The facilities that have become known to date have the disadvantage that the devices serving to limit the wake-up signal are expensive, complicated in their mode of operation and also prone to failure are; They also have a relatively high space requirement, so that the works equipped with them are not for small Alarm clocks, such as travel alarm clocks, etc., can be used.

For example, an electric alarm clock has become known, which is operated by a ^ nem so-called centrifugal elevator (folding armature elevator) is driven. To limit the duration of the wake-up signal, a ratchet wheel is provided, which is activated at the same time as the elevator's magnet armature is operated. This alarm clock mechanism has the disadvantage that the additional actuation of the 3 ratchet wheels significantly reduces the energy requirement increased, furthermore the wear and tear associated with this alarm mechanism arrangement is not sustainable.

Various attempts to remedy these drawbacks have only achieved considerably complicates the structure of the devices without a sufficient " to have a corresponding improvement and thus acceptable elimination of the disadvantages.

Furthermore, a clockwork arrangement with an alarm device has become known, in which the limitation of the minimum duration of a fast running Gear part of the movement was made dependent.

109 8 33/092 0 «D _{Ofl (G} , _ML

When the alarm signal started, a coupling device was used a counting wheel is mechanically connected to the clockwork gear and thus the wake-up signal duration is shortened accordingly. However, there is a need to do this Relatively complicated and expensive gearbox is necessary to enable intervention in the walking frame without adverse consequences.

With these wake-up devices, it was also a considerable disadvantage that either there was no possibility of having the awakened person carry out another manual alarm signal limitation, or it was such a manual intervention only through the actuation of a contact in series with the contact that triggered the wake-up signal lying switch feasible. In many cases, however, it was forgotten to switch on the signal generator for the to carry out the next wake-up period, so that the necessary operational safety for a daily automatic wake-up electric alarm clock, was not given without checking every evening. This operational security but is a prerequisite for an uninterrupted electric alarm clock, because this is the only way to ensure that the user is regularly woken up at a specific time every day.

It is also an electrical alarm device has become known at which of the shut-off levers simultaneously switches on the dial lighting serves. In this case, however, there is no guarantee that the dial lighting will be operated and at the same time If the wake-up signal is triggered, the wake-up signal can be issued without being disturbed.

The task on which the invention is based is to be seen in that an electric alarm clock is to be created in which both the possibility of a reliable, automatic wake-up

109833/0920

si ^ nal limitation

as well as an automatically resettable, manual alarm signal limitation is given and in which both the manual alarm signal limitation and the activation of the by means of an operating lever Dial illumination is to take place, with such a design, that e.g. also with the shut-off lever actuated to illuminate the dial and the wake-up signal triggered at the same time, the undisturbed delivery of the wake-up signal is guaranteed, and no fast-moving ones and -actuated mechanical devices for wake-up signal limitation, but in which only parts are used, Binding is exposed to the slow, force-translated movements and can therefore work reliably and with low wear.

The object is achieved according to the invention in that the upon entry the wake-up signal triggering a closed wake-up signal circuit when the automatically resettable shut-off lever is actuated the manual alarm time limit is self-holding interruptible that this self-sustaining interruption from the electric alarm clock Cancellation of the alarm signal triggering by the alarm clock control device can be canceled again and that when the shut-off lever is actuated the dial lighting can be switched on, with a lever-like arrangement which can be actuated by the alarm clock control device is that when the wake-up signal is triggered at the moment the dial lighting is switched on, the one that comes about Wake-up signal circuit can be closed and, in spite of the shut-off lever still being actuated, can only be interrupted again when it is actuated again is.

There is an expedient form of the inventive solution to this problem in that the wake-up signal generator (small buzzer, small alarm clock) is closed and dependent on the occurrence of the hour wheel controlled by its further rotary movement and via a second with the first 109833 /

Contact lying in a row, also through the incident hour wheel closed, but only controllable by its axial movement contact can be energized, and this energization either automatically by rotating the hour wheel and the associated opening of the first contact, or manually by means of the Sampling lever caused by an interrupter, forced, self-holding separation of the per se by the collapsed hour wheel closed second contact can be interrupted, wherein when the hour wheel is lifted out of the alarm setting wheel, the second contact can be automatically released by the first and at the same time the interrupter element, which so far has been causing its separation to be self-sustaining, can be triggered and thus returned to the starting position the manual alarm signal limitation can be reset automatically.

A further development of the invention is seen in the fact that the hour wheel The alarm clock wheel arranged opposite it occurs in two stages, with a conductive connection in the first stage between the hour wheel and the alarm clock setting wheel while the movement angle of the Hour wheel can be produced, which after this period of time by further collapse of the hour wheel on the second stage again is interruptible.

109833/0920

1799352

Another inventive development is seen in that the hour wheel made of plastic has tooth-like, steep-sided cams offset from one another on its side facing the alarm clock, and the alarm wheel is provided with a corresponding arrangement of gaps so that the cams can fall into this and an axial displacement during the rotary movement is possible, with the hour wheel carrying an annular contact plate which is used for sliding contact on it, and on the end face carrying the cams a bent contact tongue connected to this contact ring next to one of the cams, against the direction of movement looking, is arranged that the end of this extends over the steep plank of the cam by the movement path corresponding to the alarm signal duration, with such a deflection that when the hour wheel is lifted the end of the contact tongue does not touch the alarm setting wheel when it falls of the hour wheel in the gaps of the alarm setting wheel, however, for the duration of the desired alarm signal, an electrical contact between the face of the alarm clock setting wheel and the contact tongue, which is now almost flat against the hour wheel, can be closed, which can be interrupted again by the tongue falling into the gap.

These solution ideas are expediently supplemented by a number of further inventive designs of the subject of the application.

With this solution presented above, it is possible to produce an electric alarm clock mechanism which has only a few moving parts, which are also insensitive and which run through the actuation paths transferred to them at a relatively low speed and thus work with little wear.

109833/0920

The object according to the invention is expediently used in connection with electric and electronic clockworks, clockwork and V / corner device are fed from a common power source and thus the possibility of months or years daily automatic wake-up at a certain time with manual deactivation of the wake-up signal is given.

The invention is explained in more detail in the drawings attached to the patent application. They represent:

109833/0920

The alarm clock mechanism is shown in FIGS. 1a and 1b. Me representations are essentially based on the the actual Alarm device related parts and assemblies limited; with regard to the type of alarm clock mechanism causing the triggering the various previously known embodiments of electrical and electronic balance mechanisms can be used. It is natural A prerequisite that a clockwork is used that is spatially favorable, i.e. designed as flat as possible, with it the spatial advantages given by the wake-up device according to the invention can be made appropriately usable.

The minute shaft 2 is mounted in a front plate 1 of the movement. On the minute shaft 2, a wheel 3 is arranged, which is in engagement with the change wheel 4, which by means of a bolt 5 in the front plate 1 of the work is rotatably mounted. The change gear drive 6 is in engagement with the hour wheel 7 of the alarm clockwork, which is mounted axially displaceably in front of the wheel 3 on the minute shaft 2.

These described components are arranged between the front plate 1 and a front plate 8 which carries the dial 9. The components of the alarm clock mechanism (not shown) are mounted or inserted between the front panel 1 and the rear panel 1a. In the front plate 8, the socket 10 is guided, which is firmly connected to the alarm clock hand wheel 11 and carries the alarm clock hand 13 shown in FIG. 3 on the front attachment.

109833/0920

V798352

The hour wheel 7 is carried by the socket 14a, which on her front lug 15a carries the hour hand, not shown. By means of a tension spring 14 screwed onto the front plate 1 the hour wheel 7 is always pressed against the alarm setting wheel 11 via the beads 15 incorporated in this spring. The hour wheel 7 has on its side facing the alarm setting wheel 11, some sawtooth-like, one-sided steep-sided cams 16, which when entering the wake-up time in, in the area of the alarm setting wheel 11 recessed gaps under the influence of the tension spring 14 can occur

The alarm setting wheel 11 can be adjusted by means of an alarm setting drive which meshes with it 17 set the desired alarm time using the alarm clock hand 13 (Fig. 3)

The alarm setting wheel 11 grinds both parts 8, 11 by means of a bead 18 formed in it on the front plate 8 of the alarm mechanism are kept blank so that an electrically conductive connection between the front plate 8 and the alarm setting wheel 11 is possible.

In Figures 4a and 4b, the hour wheel 7 is shown as an individual part. Two cams 16 arranged on different radii and a further, somewhat differently designed cam can be seen there This cam 19 also has a formation 20 on the side, on which a contact tongue 21 rests under slight pretension.

This contact tongue 21 is part of an annular contact plate 22 which is placed in a corresponding recess on the side of the hour wheel 7 that carries the cams 16, 19. A fixation and retention of the annular contact plate 22 on the 10 9 8 3 3/0920 is achieved by means of an attachment 23 and various gaps 24 which cause jamming

- 10 -

S-tiindenrad 7 allows. The contact tongue 21 is from the contact plate 22 formed by punching out (Pig. 4a) and sucked out of this by a corresponding amount, so that the tongue can place with its front end on the formation 20 of the cam 19 with a slight bias (Fig. 4b)

In the exemplary embodiment of the hour wheel 7 of FIGS. 4a + 4b, two cams 16 and the nocicen 19 are provided. In the hour wheel 7 Opposite alarm setting wheel 11, gaps corresponding to the positions and spatial dimensions of the cams 16 and 19 are provided, so that once in 12 hours under the action of the tension spring 14 the hour wheel 7 can collapse into the alarm setting wheel · Here the arrangement of the cams 16 and 19 to the gaps of the alarm setting wheel 11 is chosen so that before reaching the alarm time, so before the spring force exerted on the hour wheel 7 by the tension spring 14 is taken over approximately evenly by the three cams 16, 19 upon collapse will. Shortly before the axial displacement of the hour wheel 7 caused by the incidence in the gaps, the cams 16 are already reached their gaps, so that the entire axial force is now transmitted to the cam 19, triggering the incident and thus the wake-up signal thus only depends on the cam 19.

The contact tongue 21, which is slightly pretensioned on a formation 20 of the cam 19 is applied (Fig. 4b) is with its front end 25 by a certain amount over the front, steep edge of the their associated cam 19 also (Fig, 4a) so that when the Hour wheel 7 in the alarm setting wheel 11, the front end 25 still on this (11) rests and so a contact between the contact tongue 21 applied to the hour wheel 7 made of plastic, annular contact plate 22 and the alarm setting wheel 11 he

109833/0920

- 11 -

The protruding end 25 of the contact tongue 21 is chosen dimensionally so that that its effective length corresponds to the maximum desired signal duration of movement of the hour wheel 7 on the Corresponds to the height of the radius corresponding to the arrangement of the contact tongue 21.

Here, the end 25 of the contact tongue 21 rests on the surface of the alarm setting wheel 11 under pretension. The end of 25 will be here pressed flat against the face of the hour wheel 7. By means of an annular elevation provided on the face of this wheel 26, however, prevents the contact plate 22 from resting directly on the surface 27 of the alarm setting wheel 11 and thus with this contact can give. Reference is made to FIG. 3, which is a more detailed sectional side view represents the alarm device according to the invention.

Has the hour wheel 7 increased by the amount of the steep slope of the cam 19 protruding part of the front end 25 of the contact tongue 21 is rotated, the contact tongue 21 also falls into the gap in the alarm setting wheel 11 and comes back to rest on the underlying formation 20 of the cam 19. In order to the contact between the hour wheel 7 and the alarm setting wheel 11 is interrupted and the alarm signaling ends automatically.

As the hour wheel 7 continues to rotate, it slides with the surfaces 28 of its cams 16 and 19 along the edges of the Gaps in the alarm setting wheel 11 and is hereby excavated.

copy 109833/0920

The formation 20 prevents the contact tongue 21 with its front end 25 again with the end face 27 of the Alarm setting wheel comes into contact and thus leads to renewed signaling.

The arrangement of the hour wheel shown in FIGS. 4a and 4b could also be further developed according to the invention to the effect that the annular contact plate 22 dnbh a lamination or vapor deposition is replaced by metal and the contact tongue 21 by Soldering, riveting, welding or any other suitable process with both electrical and vapor deposition is mechanically connected to the body of the hour wheel 7.

By means of the contact which can be established by means of the contact tongue 21 causes the automatic limitation of the wake-up signal duration. The annular contact plate 22 of the hour wheel 7 is used to give the alarm signal The required current is supplied via a sliding contact, which can be seen from FIGS. 1 and 5.

From Fig. 1a and 1b it can be seen that the hour wheel 7 is sensed by resilient parts 29 and 30, welohe from a switching spring 31 represent tongues worked out or molded onto them.

This switching spring 31 is by means of the bearing shaft 32 in, on a plastic part 33 integrally formed bearing blocks 34 stored, for which purpose two tabs 35 with holes are bent on the switching spring 31.

The switching spring 31 has at its other end an eye 36 which, as FIG. 1c shows, is oval and at the same time has a Siokung 37 serving to establish contact

109833/0920

1790352

On the plastic part 33, a contact piece 38 is arranged, which is seen in particular from Figure 5d, by inserting and bending a U-shaped molded part is made "On the one hand longer end 39 is used to connect the to the T _e ü heranzuführenden wiring.

During the axial displacement of the hour wheel 7, the tongues and 30 experience a through the beads AO and 41 attached to their ends Deflection, the switching spring 31 being tilted about the bearing point 32. The contact bead 37 thereby reaches the contact piece 38 to the edition. As a result, via the connecting part 39, the contact ™

part 38, the contact bead 37, the eye 36, the switching spring 31, the Tongues 291 30 and the beads 40,41 tension on the annular Contact plate 22 of the hour wheel 7 brought up.

For safe actuation of the switching spring 31, it is advantageous to the the ring-shaped contact plate 22 sensing, the hour wheel 7 frontally enclosing tongues 29 and 30 to bend to the side and to form the beads 40, 41 provided at the front end in the shape of a dome, so that when the hour wheel 7 is axially displaced, the J This movement is transmitted by a preferably rolling movement the beads 29,30 on the end faces of the hour wheel 7 takes place. This creates a tension between the switching spring 31 and Hour wheel 7 avoided and a uniform transmission of the movement ensured.

Due to the axial incidence of the hour wheel 7, a contact via the contact tongue 21 and the alarm setting wheel 11, as well as a contact via the parts 37 and 38 is closed, so that the

Wake-up signal circuit from the front plate 8, which at one pole of the

109833/0920 Power source is present,

1798362

after connection 39 and the alarm signal generator (small buzzer, small alarm clock) can be closed.

The second contact formed by the parts 37 and 38 is used for the so-called manual limitation of the wake-up signal duration · Purpose: this contact device is to prevent any manual interruption the wake-up signal, but at the same time the guarantee to give that this deactivation of the alarm signal by the cadrature of the alarm system again after the signal has been given is reversed. For this purpose, the shut-off lever 42, which is common with all alarm clocks, is provided, which has one in a hole in the front plate has movable stop 43, which limits its actuation movement and a spring 44 to the necessary return the pivot and bearing point 45 experiences · The extension 43 moves within the bore 46, which the possible operating angle of the Lever 42 is determined. (Fig. 1a and 1b)

The parking lever 42 also has an arm 47 which has a roller 48 wearing. When the lever 42 is depressed, the roller 48 is deflected via the arm 47 and touches the spring 49

The return spring 44 is anchored with its end 50 in a bore 51 of the front plate 1 of the clockwork, which is connected to one of the poles of the common supply current source. About the bearing point 45, as well as the supports 52, Xmt the Abetellhebel 42 with the return spring 44 and thus also with the front plate 1 electrically connected, so that when the roller 48 touches the spring which is connected to the dial lighting, it is switched on .

109833/0920
- 15 -

The dial lighting is switched on for everyone Depressing the parking lever 42.

The extension 43 of the shut-off lever 42 is provided with an actuating spring 53 connected, which acts with its front end 54 on a so-called breaker lever 56 pivotable about its bearing point 55, like from the pig. 1a can be found.

When the parking lever 42 is depressed, its movement is controlled by the Actuating spring 53 is transferred to the interrupter lever 56, since this is with its front end 54 on the rear side of the transfer lever 56 is present. This is thereby pivoted against the return spring 57, which rests on the support point 58, and thereby arrives with his front end 59, which, as can be seen particularly from FIG. 1c, is provided with an elongated hump 60 and a detent 61, between the contact bead 37 of the switching spring 31 and the contact part on the plastic part 33.

If this operation takes place when the hour wheel has not fallen in, i.e. when If the contact 37, 38 is not closed, the front part 59 of the interrupter lever 56 would not be locked between the parts 37 and 38. If the shut-off lever 42 is no longer actuated, then it returns next to it the interrupter lever 56 also returns to its original position under the action of the return spring 57.

109833/0920

- 16 -

An appropriate design of the breaker lever 56 ordered therein, ; that this is made in the plastic injection molding process and the Return spring 57 is molded on the lever in the form of an elongated, thin flag, which is in the usual way on a pin or Bolt 58 is applied under pretension (Fig. 2).

Another possible design of the interrupter lever 56 is that on this both - as described above - the return spring 57 and the actuating spring 53 are formed in the form of elongated flags molded in the plastic injection molding process and the flag corresponding to the actuating spring 53 is acted upon by the shut-off lever 42 . All three parts can thus be manufactured as one piece in one operation and do not require any special fastening. Such an interrupter lever is shown in FIG. The interrupter lever 56 'pivotable about the bearing point 55' has a resilient, resetting flag 57 'and an actuating flag 53''which is actuated by the shut-off lever 42' via its stop 43 '. Both plastic tabs 53 ', 57' are molded onto the body of the interrupter lever 56 'and are produced with this in one operation. The plastic ancestor 53 'is bent angularly off \ and thereby results in favorable ways -for the spatial arrangement of the parts to each other, as well as the spring properties of the flag 53'.

If the shut-off lever 42 is actuated during the alarm signal, i.e. if this is to be limited manually, the front end 59 of the interrupt lever 56 operates under the influence of the shut-off lever 42 over the actuating spring 43 a compulsory separation of the both contacts 37 and 33, which in this functional phase yes the sunken hour wheel 7 are closed and latched simultaneously between these two parts.

109833/092 0

Interrupter lever 56 does not return to its starting position, when the shut-off lever 42 is released. The interruption of the contacts 37, 38 thus eliminates the manual alarm signal limitation causes. The shut-off lever 42 can now be actuated further if the operator briefly illuminates the dial wishes to make.

After the completed contact, the hour wheel 7 is by its from Clockwork caused further rotation from the gaps in the alarm setting wheel lifted out and here the switching spring 31 again around its bearing | shaft 32 pivoted. Contact bead 37 moves away from the contact piece 38, at the same time now between these two parts The interrupter lever 56 which has been locked is released and returned to the starting position by its return spring 57. at the operations of the shut-off lever 42 to be carried out outside of the wake-up time are indicated by a sensible, yet to be explained in more detail Device prevents the interrupter lever 56 from being brought into the area of the contacts 37 »38 and thus to uncertainties in the Wake-up signal leads.

The device described above represents an expedient embodiment of a manual wake-up time limit, because this limit, which is reversed by lifting the hour wheel 7, the alarm device is used in the next alarm period effective again without the wake-up time limit having to be reset by external manual action.

109833/0920

- 18 -

The tension spring 14 has an extension 62 at its outermost End 63 has a bent tab or extension 64. This arrangement can be seen particularly clearly from FIG. 1c.

When the alarm signal is over, the hour wheel 7 is out of the gaps of the alarm setting wheel 11 is lifted, the tab 64 arrives in the Movement range of the breaker lever 56 and at the same time in one

fc limiting slot 65. It blocks the interrupter lever 56 against further action Deflection in the area of the contact point 37, 38. When the shut-off lever 42 is subsequently actuated, its movement is stopped the resilience of the spring 53 is compensated. Here, the interrupter lever 56 tense, but at the same time in its movement by the shoulder pressed against the wall of the delimiting slot 65 64 inhibited. The main purpose of this facility is to prevent that when the shut-off lever 42 is actuated to illuminate the dial and the alarm signal is triggered at the same time, the alarm signal by the actuated shut-off lever 42 via the lower

'breaker lever 56 is immediately deleted and the alarm clock is therefore not can sound. In the event of a wake-up signal solution, namely the approach 64 of the extension 62 by the actuated parking lever 42 biased interrupter lever 56 pressed against the wall of the delimitation slot 65, so that this also with incident Hour wheel 7 and the associated relaxation of spring 14 cannot escape from this position »The deformation of the tension spring 14 when the wake-up signal is triggered takes place in itself

109833/0920

- 19 -

The actuation paths, forces and characteristics of the springs 53, 57 and 62 are matched to the friction conditions prevailing between the interrupter lever 56, the extension and the wall of the limiting slot 65 so that when the shut-off lever is released again 42 and the wake-up time triggered shortly beforehand, that is to say the hour wheel 7 has fallen, the extension 62 of the tension spring 14 can only be released from the assumed position when the bias of the breaker lever caused by the actuating spring 53 is released 56 has reduced so much that a separation of the contacts 37, 38 by this or its stool 60 is no longer possible. f

The approach 64 on the extension 62 thus achieves that upon actuation of the shut-off lever 42 for dial illumination and simultaneously occurring alarm signal triggering this despite actuated Shut-off lever 42 and is not hindered in spite of the pretensioned breaker lever 56. To set the manual wake-up time limit, in In this case, another actuation of the shut-off lever 42 is necessary, which then leads to the separation of the contacts 37, 38.

In FIG. 2 of the drawing documents, one is opposite to the Arrangement of Figure 1 structurally modified embodiment of the invention Alarm clock control shown. This is particularly suitable for use with very small alarm clocks, e.g. travel alarm clocks. Compared to FIG. 1 a, this differs primarily through a different interrupter lever 56 which - as already described above - is made of plastic and has two flags 53 ', 57' with are injection-molded, which carries the actuating spring 53 of the shut-off lever 42 and the return spring 57 of the interrupter lever 56 of Replace Fig. 1a. 109833/0920

The shape of these resilient breakdowns is the special spatial requirements adapted, as it is present in this alarm clock control device, which is intended especially for small alarm clock mechanisms.

The extension 62 'of the tension spring 14 does not have a bend 64 at the front end 63', but the end 63 * protrudes between the breaker ^{lever 56 f} and the bearing block 34 of the artificial part 33 End 63 * in the path of movement of the breaker lever 56 '. If the shut-off lever 42 'is actuated, the end 63' is pressed against the bearing block 34 and _/ prevents the breaker lever 56 'from pivoting out. If the alarm signal is triggered at this moment, i.e. if the hour wheel engages, the end 63 'of the tension spring 14 remains in the pressed position between the breaker lever 56' and the bearing block 34.The bending of the extension 62 allows the hour wheel 7 to collapse in this! Functional phase so that in spite of the actuated shut-off lever 42 * and in spite of the jammed spring end 63 'the alarm signal is released. To manually limit the alarm signal, the shut-off lever 42 'must also be actuated a further time.

The forces and characteristics are also in this alarm clock control the lugs 53 'and 57' to the between the breaker lever 56 ', spring end 63 'and bearing block 34 prevailing friction conditions are chosen so that that a release of the spring end 63 'by the released shut-off lever 42 returning to its rest position is then possible is when the remaining bias of the breaker lever 56 'is no longer sufficient to separate the contacts 37 » 38 to effect.

109833/0920

The flag 57 'of the breaker lever 56 rests on a block 58 which is inserted in the front panel 1.

In the figure 5a is shown how that of the manual alarm time limit Serving parts are combined on a plastic part 33 and are mounted in this assembly on the front panel 1 of the alarm clock. The assembly is conveniently done by means of the hole « 66 introduced screws or rivets.

FIG. 5a shows a plan view of the switching spring arrangement 31 Switching spring 31 is freely pivotable on the bearing shaft 32, which is provided in recesses in the bearing blocks 34 in the manner of a wedge 68 can be blasted.

Figure 5b shows the unit of the switching spring 31 _with the other components in the functional phase, in which, after the manual wake-up time limit has been carried out, the contacts 37 and 38 are separated by the breaker lever 56, but the switching spring 31 is still acted upon by the sunken hour wheel 7. *

Figure 5c shows the unit of the switching spring 31 with the other components, once in the functional phase in which the contacts 37, 38 are closed, i.e. the wake-up signal is given (extended switching spring 31) and secondly the position of the switching spring 31 in the functional phase in which this was deflected into the open position by the hour wheel 7 lifted out of the alarm setting wheel 11 (dashed solenoid spring 31).

109833/0920

The part 36 of the switching spring 31 has on the side from which it is acted upon by the interrupter lever 56, a formation or Aufbiegung, through which the penetration of the breaker lever 56 'and the separation of contacts is favored.

In the structural unit according to FIG. 5a, one of the bearing blocks 34 serves at the same time as a stop 67 for the interrupter lever 56.
