Device for triggering and determining the duration of the ringing of the bell of an electrical timepiece, e.g. B. an alarm clock '- ■; ~ ~ - "-

The invention relates to a device for triggering and for determining the duration of the ringing of the bell of an electrical timepiece.

In particular, the invention relates to a device for closing, for timing and opening an electrical circuit in very "small size" timepieces, i.e. miniature devices. ■. ■ .- -. "■ - ■" - ■ -.-

In timepieces or clocks that use an electrical energy source When using a battery, the bell usually consists of in relation to the control system relatively large, energy-consuming Share. -. "■ \..

On the other hand, since the miniature design of these timepieces requires a reduction in the volume of the / battery, ■■■■■■ - ■■ ".- ■■" - "■ - ^: -. '■ '"'■:■' / ■ '- ^ - ^; / 2

whose electrical capacity is low, and the fact that the bell rings must be limited to the usual period of time ", which is usually about twenty seconds for a weeker.

The main aim of the invention is to make this very short measurement of the duration of the ringing by means of a simple mechanism bring about.

Another object of the invention is to provide an apparatus with very small dimensions, which are also distinguished by the design and shape of their various parts for the Production of alarm clocks is the usual cheap way of producing the parts and assembling them.

The gate direction according to the invention has the following parts: on the one hand an electrical switching contact, which consists of at least one electrically isolated from the electrically conductive ground of the device, stationarily attached contact spring or lamella and an elastic switch contact spring attached to the circuit board of the device or lamella, which by holding it in and out an axially extending in one or the other direction movement of the hour wheel is controlled, the one helical running, preferably protruding punched out, ramp or guide surface and carries a block, on the other hand Aggregate of parts, -by the reciprocating axial control movement of the hour wheel is effected, and which are freely rotatable about the axis of this wheel, namely the following parts: one of

the outside of the device or the alarm clock can be activated by the ringer dial, by which the unit can be adjusted in the opposite direction to the direction of rotation of the hour wheel, an eccentric one to the Läutwerkzeigerrad about an axis parallel to its axis pivotably mounted rocker, the one with radial force direction lokkensegmait that works with the block of the hour wheel and forms a helical ramp or has guide surface, which in the axial direction with the correspondingly assigned ramp or guide surface of the hour wheel cooperates, and a return spring for the rocker in such an arrangement that they by the radial action of the block of the hour wheel on the neck segment when turning slowly the hour wheel is tensioned and suddenly relaxed after crossing the highest part of the squat segment in three time segments, where the relaxation of the spring in the three time periods causes the following: the backlash in the gear of the pointer value Yf is reduced, by sliding the helical guide surfaces together (Ramps) one guide surface quickly reaches the other and quickly falls off the other behind the other off, a stop on the ringer wheel holds the rocker in its rest position and limits the relaxation of the peder Rocker e.

The result of the helical sliding of the guide surfaces against each other and their falling away from each other triggered rapid axial movements of the hour wheel in one direction and the other cause first the closing and then the opening of the electric Switching contact, namely the latter after a period of time,

which is determined by the shape of the curl segment of the rocker ".
This switching contact can be a single or a double switching contact and can be designed to work as a two-way or multi-way switch. The porm of the curl segment of the seesaw, which means
of the block of the center or hour wheel is pivoted by radial pressure forces, while the return spring is tensioned, is designed so that this process on the rocker, viewed as its angular movement, takes place as slowly as possible, so that a disruption of the alarm clock regulator " is avoided.

In the following, the operation of the gate direction is particular using the! ig .. 3 / to β described ·

In-Mg. 3 and 4 the device is shown at the time in which the block 7 firmly connected to the center wheel 5 at its slow rotation in the direction of the arrow f at the vertex the radially inclined surface 12b of the hook segment of the rocker 12 arrives. During this movement, the rocker 12 is moved in the direction of the Arrow f3 and pivoted at an angle o £, causing the wire spring 13 is tense and acts from this moment on as a driving force, and ,, while the Sehnabel or Voi ^ a? Ung 12c over the inclined Hache 7a of the block 7 slides, presses it or he on the center wheel 5 in its normal direction of rotation (arrow f). This process causes the whole movement of the hands to become a drive mechanism is made ... instead of being the recipient of the movement and a reduction in the backlash of the Zaijh or! takes place in a direction opposite to normal sighting is. At the same time, those with the center wheel: 5 are fixed resp. integrally connected, helically extending ramp 5a and the screw-like ^ extending ramp 12e of the rocker into one Position gelargfc, in which their screw-shaped! Laugh at each other opposite, lie

While the block 7 continues its rotation, there is a projection 12c of the rocker 12 this free, the. then under the action

This release principle, as should be emphasized, enables very short periods of time for ringing to be achieved, which are determined by a wave "whose angular velocity is relatively low. The entire" device takes up little space both in the durometer and in the dioke . "- ^-:.: ..- .. .. - ^=!" .-
