Intercom for a toy figure, in particular for a doll

The invention "relates to a speech mechanism for a toy figure, especially for a doll, which one by means of a Has delay member having spring mechanism around a bearing shaft rotatable record, in the tone grooves during of the barrel a scanning needle of a pivotable about an axis approximately parallel to the bearing shaft, resiliently in its starting position pressed tonearm engages, the one on the record remote side a sound transmission member is resiliently applied, wherein the bearing shaft with the record can be tilted in this way is that the needle is in and at the beginning of the speaking process at the end of which it can be brought out of engagement with the tone grooves of the record.

822/0812 _{0RIG1NAL1NSPECTED}

Talking devices for toys, especially for dolls, must meet a number of requirements in order to be suitable for its intended purpose. These requirements include in particular a structure that is as simple as possible, but nevertheless ensures that the speech unit works reliably should be.

The known speech units generally meet this requirement not full. For example, prepares in the known speech units, provided they are not operated with an electric motor are, the flawless and as even as possible delay of the spring mechanism difficulties. About this delay a centrifugal force-dependent moving element is used very often, which on the one hand is relatively complicated in structure and, on the other hand, is a source of frequent disturbances. Furthermore, it must be ensured with the speech units that at the end of the speaking process the needle sj.ch out of the tone grooves the record loosens and the tonearm with the needle can easily return to the starting position, in order to restart Actuation of the speech unit to trigger a new speech process. It is known for this purpose, the bearing shaft of the record and thereby tilting the record. In the known speech units, however, the tilting movement generally takes place solely depending on the actuation of the cord used to tension the spring or the like. Result from this there are also difficulties regarding an impeccable

609822/0812

Triggering the record "or stylus. Associated with this is also the difficulty of being in perfect vein without however to exert too much pressure on the tonearm, the vibrations of the tonearm on a Sehall transmission element "or the

radiating
to transmit the sound / membrane. A known proposal for the transmission of the sound vibrations from the tonearm to the diaphragm is to provide a resilient part, which rests against the tonearm approximately in the middle of the diaphragm and which can vibrate slightly and transmits its vibrations to the more firmly mounted diaphragm. This approach leads to good results in terms of sound radiation and sound generation; however, the result is a relatively complicated structure with a corresponding susceptibility to failure. .

The invention is therefore based on the object of creating a speech mechanism for toy figures, in particular for dolls, which is characterized by its extremely simple structure, good functionality and satisfactory sound radiation, while avoiding the deficiencies of the prior art should.

To solve this problem, it is proposed according to the invention in a speech unit of the type mentioned that the Bearing shaft carries at least one intermediate gear of the spring mechanism, which on the one hand is driven by a drive gear moved by the spring is driven and on the other hand the

609822/08 12

Delay element comprehensive part of the spring mechanism drives that further the delay element of a rotating flywheel mi "c is formed with an eccentric mass distribution, and that Arrangement and direction of rotation of the intermediate gear relative to the drive gear and the output gear meshing with it as follows are chosen that when stopping the drive gear at the end of the speaking process the intermediate gear while tilting the Bearing shaft comes out of engagement with the output gear and remains in this position during the rotation of the drive gear, which takes place when the spring is tensioned, and when it rotates again Movement of the drive gear under the action of the Spring at the beginning of the speaking process by tilting the

engaged
pung of the bearing shaft / arrives at the output gear.

The speech unit according to the invention thus differs from the State of the art basically in that only a very simply constructed flywheel with an eccentric rotor is used as the delay element Mass distribution is provided. This not only changes the structure of the drive for the speech unit the known speech units considerably simplified. It Rather, it also results from further inventive Training the advantage that the tilting movement of the bearing shaft for the record when stopping with the Spring-coupled drive gear reliably caused as the flywheel continues to run to a certain extent via the intermediate gear arranged on the bearing shaft with the

609822 / QS12

Spring-coupled part of the spring mechanism leads the intermediate gear reliably when the drive gear is stopped brought out of engagement with the abrasion gear and as a result the bearing shaft and the record are tilted perfectly. So it arises compared to the known speech mechanisms on the one hand a simplified structure and on the other hand an increase in reliability.

This makes the tilting movement of the bearing shaft very easy produce that one end of the bearing shaft is guided in a slot that is approximately tangential to the drive gear and extends approximately radially with respect to the output gear. It is useful here in the area of the intermediate gear the drive gear during the speaking process in the direction to turn on the output gear. With renewed winding the Spring then of course a rotation of the drive gear takes place in the opposite direction, i.e. in the area of the intermediate gear away from the output gear.

Advantageously, the intermediate gear of two is coaxial arranged pinions of different diameters, whose smaller one with the drive gear and whose larger one meshes with the output gear. With this training leaves There is also a change in speed due to the intermediate gear make, whereby additional components in the spring mechanism can be saved under certain circumstances.

809822/081 2

When tilting the record, you can easily move backwards To reach the starting position of the stylus or the tonearm, the trajectory of the stylus is expedient of the tonearm are roughly in the plane which is from the axis of the bearing shaft in the different tilted positions is determined.

It is also advantageous if the axis of rotation of the flywheel is arranged eccentrically to this. In this way, an eccentric mass distribution is obtained from the outset. In addition, the flywheel can also have a different cross-section, for example different thicknesses, be carried out in order to enlarge the eccentricity with small dimensions of the flywheel.

The spring is advantageously pulled up in itself in a known manner in such a way that a cord disc connected to the drive gearwheel is arranged coaxially to the drive gearwheel, which for receiving an elevator cord tensioning the spring serves. The elevator cord can pass through a housing opening and at its free end a stop member which inhibits the further flow of the spring when it hits the housing, preferably a grip ring.

For certain applications of the speech unit, however, it proves to be favorable if the shaft of the drive ten wheel has a

609822/0812

- ι -

Profile approach od. The like. For a key. This approach can be provided with or without the cord disc.

In particular in the case of a speech unit of the design explained above, it is further proposed according to the invention that as a sound transmission element, one drawn in at one point, advantageously in the middle, in the direction of the tonearm, there, The diaphragm directly adjacent to the tonearm is used, the edge of which is attached to a frame which is approximately perpendicular in one direction is set resiliently to the record level on the housing of the speech unit. Such a resilient mounting of the On the one hand, the frame itself has a very simple, less prone to failure structure. On the other hand, in spite of everything, it becomes a good mobility of the membrane and, as a result, perfect sound radiation guaranteed. Of course you can such a storage of the membrane not only "in a speech unit the training explained above can be provided. Rather, such membranes can be used in all possible speech mechanisms Find application.

The frame is movably supported in relation to the housing expediently in such a way that the frame is tiltably mounted on one side of the housing and on the opposite side printed by a pressure spring to be pressed onto the housing is. Here, the frame advantageously has a

609822/0812

a hole in the housing penetrating bolt on the
the pressure spring is pushed on, whereby a corresponding guidance of the frame with the membrane can be achieved.
For tiltable mounting on the frame, at least one radial projection is preferably provided which has at least one
hook-like approach of the housing engages below. If in this
If the guide consisting of the bore and the bolt is also provided, the interacting surfaces of the hook-like projection and the radial projection can run essentially parallel and transversely to the axis of the bolt, since lateral displacement is prevented by the guide. In general, a pair of radial projection and hook-like approach is sufficient. However, it is more favorable if two such pairs are provided.

Further features, details and advantages of the invention emerge from the following description of a preferred exemplary embodiment with reference to the drawing, with reference to advantages of the Subject of the invention, which arise for the person skilled in the art on the basis of the state of the art, has not been specifically pointed out, however, these are also attributable to the invention. They show, each schematically:

The speech mechanism shown in the drawing has a total with 1 designated housing, which consists of a lower part 2, that the spring mechanism / u. Like. Receives and from a lid 3 is covered. The cover 3 carries the record 4 on the top and pressed into the starting position by a spring 5, by means of a bolt 6 pivotably mounted tonearm 7 with the stylus 8, which engages in the sound grooves of the record 4- in a manner known per se.

The tonearm 7 lies on that of the record 4 and thus the Needle 8 on the opposite side of the drawn-in central region 9 of a membrane 10. The membrane 10 is like figure 1 can be clearly seen on a frame 11, which is shown in the Embodiment has approximately ring shape, attached with its edge. The frame 11 itself is on the cover 3 mounted tiltable. For this purpose, the cover 3 has hook-like lugs 12 on its upper side, preferably two lugs, on. These approaches reach under radial projections 13 of the frame which are approximately parallel to the main surface of the cover 3 On the side opposite the projections 13, a bolt 14- which runs approximately perpendicular to the record 4- (in the operating position) and has a bore is arranged on the frame 11 penetrated in a tab 15 of the cover 3. On the protruding Part of the bolt 14 is a pressure spring 16, one end of which is supported against the bracket 15, while as a support surface for the other end, one placed on the bolt14 Disc 17 is used. This arrangement ensures that the drawn-in central region 9 of the membrane 10 resiliently against the top of the tonearm 7 and thus the stylus 8 is pressed accordingly resiliently against the record 4.

The spring mechanism used to drive the record 4 is at the speech mechanism according to the invention built up only from a few parts. His exact training can be seen from the figures

As these drawing figures, in particular Figure 3, show, the Eederwerk comprises a drive wheel 18 to which a cord pulley 19 is connected coaxially and non-rotatably. on the pulley 19 is a winding cord 20 in known per se Way wound up its end with one at the same time Gripping ring 21 serving as a stop is provided. The cord 20 passes through a recess 22 in the housing wall.

On the shaft 23 of the drive gear 18 is a common one Coil spring 24 is arranged, which can be tensioned with a corresponding rotation of the shaft 23 over the cord pulley 19 and at their relaxation the drive gear 18 and thus the entire Spring mechanism offset in rotation. The end 25 of the shaft 23 protruding beyond the lower part of the housing 1 is profiled, square in the illustrated embodiment educated. An elevator key can be attached to this end with which the spring 2A- as well as by means of the cord 20 can be stretched.

The drive gear 18 meshes with a pinion 26 on the bearing shaft 27 for the record 4, both in the playback position (Figures 4, 5) and in the position of the storage " wave 27 after the end of the speech process (Figure 3).

609822/081 2

As FIGS. 4 and 5 show, the bearing shaft 27 can be tilted stored in the housing 1. For this purpose, a carrier 28 is provided above the cover 3, which has a longitudinal slot 29, which receives the end 30 of the bearing shaft in the longitudinal direction of the slot 29 displaceably. In this way the bearing shaft 27 and thus the record 4 can be tilted. The slot 29 runs approximately parallel to the circumference of the drive gear 18, so that the pinion 26 always remains in engagement with the drive gear 18.

In addition to the pinion 26, a further pinion 31 of larger diameter is arranged on the bearing shaft 27. This pinion meshes during the playback process, i.e. with the shaft 27 in an approximately vertical position relative to the bottom of the housing 1 (Figures 4, 5) with an output gear 32, which with a second gear 33 is connected coaxially and non-rotatably. The gear 33 acts on a pinion 34, which on the axis of rotation 35 for a Flywheel 36 is seated and causes the rotary drive for flywheel 36.

From the drawing it can also be seen that the longitudinal slot 29 in the carrier 28 extends approximately in the direction of the section V-V. This means that the longitudinal slot 29 is approximately tangential ' to the drive gear 18 and approximately radially to the output gear 32 runs. As a result, when the bearing shaft 27 is capped, the gear 31 moves away from the output gear 32, to the extent that that it will be released.

Figures 2 and 3 also show that the flywheel

609822 / OS1 2

te 36 not only eccentric with respect to the axis of rotation

35 is mounted, but also to increase the eccentricity has a weight part 37, the shape of which for adaptation can be changed to a wide variety of requirements. It should also be mentioned at this point that in addition to the Schwungscheite 36 Means for changing the eccentricity the mass distribution can be seen. Could do this For example, the weight part 37 is fixed in an exchangeable manner be. Another option would be to use a screw provide, the thread of which runs approximately radially to the axis of rotation 35 in order to screw this in more or less Screw to be able to vary the mass distribution.

The speech mechanism according to the invention now works as follows:

While the. Record, i.e. during the Speaking process, the record 4 is with her Bearing shaft 27 in the position of Figures 1, 4 and 5. Here the record 4 rotates in the direction of arrow 38 in FIG Figure 3 under the action of the relaxing drive spring 24, The rotary movement of the spring mechanism is delayed and stabilized by the flywheel 36. During the Rotation of the record 4 in the direction of arrow 38 pivots Tonearm 7 around the bolt 6 in the direction of arrow 39 in FIG 4, the stylus 8 moving away from the edge of the record 4 too moved to their insides. As soon as the speaking process ends

$ 0982 2/08 12

is, the handle 21 strikes the elevator cord 22, which is winds on the cord disc 19 during the speaking process, "against the wall of the lower housing part 2, as shown in FIG 3 and 5 is shown »By striking the handle 21, a further rotation of the drive gear 18 in the direction of the arrow 38 prevented. At the same time, however, the flywheel 36 rotates and with it the output gear 32 and the greater tickle 31 of the transmission gear 26-31 in the original Direction a little further. The arrangement of the longitudinal slot 29 tangential to the drive gear 18 and radially This slight further rotation causes the transfer gear 32, that the pinion 26 is disengaged from the output gear 32 becomes, resulting in a tilting movement of the bearing shaft 7 and thus the record 4 in the direction of the arrow 40 in Figure'5 leads. As a result of this tilting movement, the tip of the stylus arrives 8 out of engagement with the tone grooves of the record 4, with the result that the tone arm 7 under the action of Spring 5 returns to its original position (arrow 41 in Figure 5) »in which the stylus 8 is approximately in the area of Peripheral edge 41 of the record 4 is located.

If the speech mechanism is to be operated again, the grip ring 21 is pulled, whereby the drive gear 18 and with him the rope pulley 19 and the shaft 23 against the direction of the arrow 38 can be rotated, which causes a corresponding tension in the drive spring. During this elevator process

609822/0812

the bearing shaft 27 maintains the inclined position (FIG. 3). Should the larger pinion 31 (due to the corresponding inclination of the speech mechanism) have the effort to get back into the drive gear 32 intervene, it is hereby determined by the direction of rotation of the ibtriebsZahnrades 32 prevented during winding.

As soon as the cord 20 is completely pulled out by means of the grip ring 21 is and you let go of the ring 21, the drive gear is 18 rotated again in the direction of arrow 38 under the action of spring 24-. Here, the output gear 32 meshes again with the pinion 31 on the bearing shaft 27 whereby the record 4 · and thus also the other parts of the spring mechanism, in particular the flywheel 36, again be set in motion. It then plays again already explained process, leading to a corresponding pivoting of the tonearm 7 with the scanning needle 8 from the outside inwards on the record 4- as a result of the movement in the tone grooves.

During this pivoting movement, in a manner known per se the stylus 8 and consequently the tonearm 7 due to the profiling of the tonal grooves in oscillating movements perpendicular offset to the level of the record 4. These vibratory movements are then from the tonearm 7 i ^ area 9 on the resilient (by means of the Teder 16) pressed membrane 10 transmitted, from which the sound is emitted correspondingly amplified

609822/0812

If for any reason the use of the cord 20 with the grip ring 21 is undesirable, the approach 25 » for example a square, the spring mechanism can also be wound with a key. Under certain circumstances even the cord 20 with the ring 21 can be retained to provide a stop when the spring is completely unwound or relaxed to build. However, an embodiment is also conceivable in which the cord 20 is omitted in this case. With this one Only then does the bearing shaft 27 for the record become spring mechanism tilted when the spring 24 has completely relaxed.

In the above description it is basically mentioned that the individual wheels of the spring mechanism are gear wheels meant to be. However, it would also be conceivable, in certain applications, for the drive gear, the output gear and the intermediate gear not to be designed as gear wheels in the actual sense, but only to provide wheels that work together in frictional engagement, for example wheels with a corresponding friction lining. Such an embodiment is of course also as to be regarded as falling under the basic idea of the invention.
