United States latent O 3,080,678 VEHICULAR TOY WITH ACOUSTIC SIGNAL Alexander Girz, Nurnberg, Germany, assignor to Schreyer & Co., Nurnberg, Germany, a corporation of Germany Filed Feb. 26, 1959, Ser. No. 795,769 4 Claims. (Cl. 46-232) My invention relates to vehicular toys which have an acoustic signalling device for producing musical or noisy sounds, and particularly to toys that simulate an automotive vehicle and have a horn or simulated siren controllable by the playing child.

It is known to provide such toys with a diaphragm device for producing a musical or howling sound, the device being driven mechanically or electrically and controllable either at will, such as by a push-button, or automatically by mechanical or electrical control means, for example in dependence upon the vehicular toy making a right or left turn. In these known toys, the diaphragm device produces a sound or noise of substantially fixed pitch, although the intensity, in some cases, increases with increasing traveling speed or increasing speed of a fly-wheel drive.

It is an object of my invention to devise a vehicular toy with a diaphragm-type signalling device which, in

mannersufliciently simple. for use with toys, affords producing tones or noises of markedly differentpitch in sequence or as chords of simultaneously sounding tones.

According to my invention, I provide the diaphragm device of the toy with one or more current sources capable of providing a plurality of voltages that are considerably different from each other, for example a voltage of 1.5 volt and a voltage of 3 volts; and I connect these different voltages with the diaphragm device through a selectively actuable switch for thus controlling the diaphragm device to produce differently pitched tones or noises depending upon which particular voltage is active at a time.

By thus applying different voltages to the diaphragm device, preferably under control by mechanical devices actuable by the playing child or automatically, the sound producing diaphragm of the device is subjected to oscillations of respectively different frequencies thus producing a high or low signalling tone respectively.

In general, the diaphragm-type sound producing devices used on actualvehicles or for other applications in industry are known to have substantially one predominant frequency which depends upon the natural'frequency of the diaphragm being used so that, when the electric voltage for energizing the diaphragm device fluctuates or changes, the pitch of the sound being produced remains essentially the same, and only the intensity is varied. In contrast thereto, I have found that when a diaprhagm device for use on toys'is operated with relatively low voltage under conditions where this voltage changes very greatly, such as in a ratio of 2:1 or more, the pitch of the sound produced by the device changes very greatly so that a distinct difference in predominating frequency is observed, such difference being sufficient to cover the range of a triad, for example. As a result, and by virtue of my invention, a toy device according to the invention effectively simulates, by means of utmost simplicity, the effect otherwise obtainable only with a plurality of tuned diaphragm devices.

The invention will be further described with reference FIG. 2 is a top view of a drum-type control memberfor use in a device otherwise according to FIG. 1; and FIG. 2a is a cross section of the contact drum.

FIG. 3 is a top view of another embodiment of a control member applicable in a system otherwise corresponding to FIG. 1; and FIG. 3a is an axial view of a cam which forms part of the same control member.

FIG. 4 is a schematic top view on part of a vehicular. toy equipped with still another signalling device.

FIGS. 5 and 6 show schematically two further embodiments, respectively, of a control switch in combination with the steering column of a toy otherwise similar to that of FIG. 1.

FIG. 7 is a sectional view of a diaphragm-type sound producer applicable in toys according to the invention.

The same reference numerals are used in all ilustra-.

tions for functionally similar components respectively.

FIG. 1 relates to anautomobile toy with a steering column S and a steering wheel W on the column. Located centrally of the steering wheel W is a push-button 1 which, when depressed, displaces a disc 2 from the position A to the broken-line position B, thus shifting a con-.

trol lever 3 of a signal switching device 4. The switching device 4 has a control cam 5 whose shaft 5a is connected with a mechanical drive 5b, such as a spring-wound drive mechanism, which tends to rotate the cam 5 but is normally stopped by engagement of the control lever 3 with a projection of cam 5. Only when lever 3 is placed to the broken-line position 3' by displacement of disc 2, can the cam 5 operate by rotating continuously in one and the same direction. The cam then actuates two pairs of

spring contacts

6 and 7 in a given sequence. These spring contacts are connected with two dry-cell batteries 8 and of the diaphragm device 9 are connected in additive re.

lation to both dry cells 8 and 8 so that now a total volt age of 3 volts is applied to the diaphragm device. As .a result the device now produces a tone or noise of higher pitch.

' Instead of providing the switching device 4 with a control cam, as described above, it may also be equipped with a drum-type contact mechanism according to FIGS. 2 and 2a. The contactor drum 10 is mounted on a shaft 10a which also carries a spur gear 4a to be driven from the driving mechanism. During rotation of drum" 10, its

' contact segments 11 sequentially establish a cir'cuit-clos-I to the embodiments of toys according to the invention ing connection between the

contact springs

6, 6 and 7, 7 respectively, thus connecting the diaphragm device 9 (FIG. 1) sequentially with 1.5 volts and 3 volts in order to change the pitch of the sound being produced. I

According to the modification shown in FIGS. 3 and 3a, the switching device 4 is provided with a cam mem ber 10b with cam projections 12 which, during rotation of member 1%, alternately close the

contacts

6 and 7 thus also operating in the manner described above. In all other respects the device of FIG. 3 is similar to that of FIG. 2.

The switching devices as shown in FIGS. 2 and 3, depending upon their particular design, may be placed. in

J operation during straight-forward travel or standstill of the vehicular toy. If desired, the control structure on the steering column may be so designed that the switching device will also operate automatically when the vehicular toy makes a right or left turn.

In the toy illustrated in FIG. 4, a control switch with a cam 5 and

contact springs

6, 7 similar to those shown in FIG. 1 is used, but the switch is con-trolled by means of a separate on-off switch 13. The shaft 50 of cam 5 may be driven from an electric motor 14- which also serves as a propulsion drive for the running wheels of the toy. The motor 14 is controlled by another on-off switch 14 and is energized from one or both of the same batteries 8, 8' that energize the diaphragm-type sound producer 9. A clutch may be provided between the motor 14 and the driven running wheels to permit operating the switch device 4 at standstill of the vehicular toy.

When the switch 13 is shifted from the ofi position to the on position shown by a dot-and-dasli line, the diaphragm device 9 receives alternately 1.5 volts from battery 8 through

contacts

6, and 3 volts from series-connected batteries 8 and 8 through contacts 7, thus operating essentially in the same manner as described above with reference to FIG. 1.

In the modification illustrated in FIG. 5, the

contact pairs

6 and 7 are controlled by a control member 15 directly mounted on the steering column S of the toy. The push-button 1 in this embodiment is firmly joined with the steering column S, and the steering column is normally biased by a spring 17 in the direction indicated by an arrow 17a. When depressing the push-button 1, the entire steering column S with the control member 15 is shifted toward the right so that a projection 15a of member 15 first engages the contact springs 6, of which only one is visible in the illustration. This closes the contact springs 6 and causes the diaphragm device to receive 1.5 volts for producing a tone of low pitch. When the push-button 1 and the steering column S are shifted farther toward the right, the projection 15a engages the contact springs 7 and thus supplies the diaphragm device with 3 volts for producing a tone of high pitch.

The embodiment shown in FIG. 6 is generally similar to that of FIG. 5, except that the steering column S is provided with a disc 2 which acts upon a cam 18 rotatably mounted on a shaft 18a. Mounted on the same shaft are additional cams 18b, 18c and 18d, which when the steering column is shifted toward the right, act sequentially on a number of contact Springs 6, 7, to sequentially supply the diaphragm device with 1.5 volts and 3 volts, respectively.

While the diaphragm device may have a single diaphragm as schematically illustrated in FIG. 1, it may also be provided with a plurality of diaphragms for the purpose of producing a musical chord or other combination of simultaneously sounding tones. Such a diaphragm device is illustrated in FIG. 7. The housing 19 of the sound producer comprises an electromagnet 19a which acts upon a diaphragm 20. Mounted on top of the housing is a cover 1% to which two additional diaphragms 21 and 21a are attached. The diaphragms 21 and 21a have respectively difierent diameters for producing tones of respectively difierent pitch. The diaphragms 21 and 21a are resiliently connected with the main diaphragm by elastic links 22 and thus are excited by the vibrations of the main diaphragm. The additional diaphragms 21 and 21a are located at the bottom of two horns 23 fastened to the cover 19b. When the main diaphragm is excited by magnetic pulses, the individual diaphragms 21 and 21a are likewise excited and the device produces a melodic sound or chord.

It will be obvious to those skilled in the art, upon studying this disclosure, that my invention permits of a great variety of modifications and hence may be embodied in devices other than those particularly illustrated and described herein, without departing from the essential features of my invention and within the scope of the claims annexed hereto.
