Device for imitating the noise of a running internal combustion engine, in particular for toys

The present invention relates generally to means for playing with engine running sounds, and more particularly Operating instruments that are suitable for regulating the noise of an engine-noisy toy so that it is familiar Operating play of an engine is reproduced.

For me, one of the state-of-the-art motorized toys used for noise was usually a direct mechanical connection with a revolving member, e.g. an eagle axis. So when the wheel turned ¹ , engine noise was generated and could not be influenced independently of the wheel movement. Furthermore, such an operation does of course not correspond to the actual operation of an engine on a vehicle such as a motorcycle. For example, both when starting and when the engine is idling, the engine works even though the vehicle wheels are not turning. In addition, the lack of operating

Consequently, an object of the present invention, an apparatus for multiple imitate the sound of a running engine _t particularly for toys, which is suitable to control such noise, so that the usual operation of an engine W game is played.

Further goals in creating such a device are the requirement for an externally removable key connection for regulating the noise of the engine-noise toy and, in terms of suitability, the usual operating play of an engine by rotating in a single direction

load objects and advantages of the present invention can easily be taken from the following description and drawings, which illustrate a preferred pattern as an example g, illustrate the present invention.

In general, the present invention includes an engine noise toy, which is operated by an electric motor supplied by an electrical power source. The intensity and frequency of the noise produced by this device are proportional to the input voltage, which is brought to the engine by the power source. This input voltage is changed by regulating means so that that they make the usual operating game of the engine noises the arrangement pulls out. The regulating means, in turn, are operated by actuating means, one of them

Similarly, the bobbin wheel contains several bobbins 26, the round do a spindle rotated by the electric motor 30 27 are grown around. The electric motor 30 is a direct current motor, so that the rotational speed of the spindle 2? is proportional to the input voltage at the electric motor 30. As a result, the engine alarm imitator 21 makes noises from an intensity and frequency which are proportional to the input voltage to the electric motor 30.

The electric motor 30 is connected to the power source 31 directly through a first wire 32 and indirectly% through a second lead wire 33, the? 0 compound has the regulating means. The regulating means 70 for their part are connected to the power source 31 by a third lead wire 34-. The source of power

31 includes a motor housing 50 described below Integrated compartment 35 »This contains at least one battery 36, one electrode of which is on the lead wire

32 attached metal contact 37 touches. The other battery electrode biases against a metal bracket 38 attached to the outer wall 39 of the compartment 35 and attached to the lead wire 34. The battery 36 is powered by a Inner wall 40 and an outer wall 39 enclosed and supported, which is attached to a removable cap 41 by means of a latch 42. The cap 41 allows access to battery 36 to replace it from time to time.

The Motorenlarmnachahmer 21 and the electric motor 30 are included in the motor housing 50 which imitates a real engine in its outer structure and to a frame, Z ₀ as a two-wheeled or three-wheeled

Lets grow the frame. The motor housing 50 contains a rounded lower wall 5'11 which forms a chamber 52 on the inside. The chamber 52 is partially enclosed by the tray 35 whose outer vV'and 39 and cap 41 components of the housing 50.: _ ■ '■ - form. The chamber 52 is partially covered by a walled and built-in cylinder wall 54 which mimics an actual cylinder wall of an air-cooled engine. Several hangers 55 with holes 56 are attached in the housing 50 and are suitable for mounting the housing 50 on a frame. The cylinder wall 54 is covered at the top by a head wall in which a simulated spark plug 58 is inserted. In order to drive the illusion over, the spark plug 58 is connected by an ignition cable 60 with an imitated distributor cap 59, which sits on the compartment cap 41,

The electric motor 30, as mentioned above, has confinement over the regulator 70 at the power source 31. The regulating means 70 are suitable, the input voltage on the electric motor 30 to change and to reproduce the usual operating cycle of k engine noises from the engine noise imitator 21. In addition, since the regulating means 70 on the electrical. motor 30 and at the power source 31 only by the Lead wires 33 and 34 are connected, they can keep a considerable distance from it. The regulating means 70 can therefore be on the handlebars of a two-wheeler or three-wheeler * The regulating means 70 contain a housing 7 ^ with a bottom wall 72 and a rear wall 73 j a cylinder flange 74 protrudes to the rear.

In particular, the regulating means 70 now include the resistance coil 96 and contact means 100, which are suitable for electrically connecting the electrical power source 31 to the electric motor 30 and changing the input voltage to the latter by changing the position of the contact means 100 along the resistance coil 96. The Heguliermittel 70 is specifically designed to match _t the usual operation of the engine noise from the engine noise imitator by means of rotation in a single direction to bring forth. The contact means 100 contain a disk 101 which is attached to the base plate 97 by means of a rivet 101 '. The disk 101 has a first contact finger 102 and a second contact finger 105 which are adapted to contact the resistance coil 96 in a set order determined by their contact with the base plate 97 during the rotation of the disk 101. A projection 103 on the first contact finger 102 can run on the base plate 97 while it is rotating and can fall into the groove 99 thereof after a predetermined angle of rotation. As an extension of the first contact finger 102 in the vicinity of the resistance coil 96, a bar 104 is kept away from it by means of the boss 103 when the latter is running on the base plate 97 (FIG. 7); however, the bar contacts the resistance coil 9G ₁ when the boss 103 falls into the groove 99- (Figure 8).

When the bar 106 on the other hand, if it falls away from the projection 99 ', it contacts the resistance coil 96. In summary, the regulating means contain 70 a base plate 97 and Kontaktmitbel 100} this contain a disc 101 which is rotatable on the base plate 97 is attached and has two contact fingers 102 and 105; whose purpose is to bucket the resistance coil 96 set order to touch, which are due to their Eontakt with the base plate 97 during the rotation of the disc 101 determined.

The regulating means 70 are operated by actuating means which contain an externally removable key 128 connecting them both. The actuating means 110 contain a scale 111 which is inserted in a cutout 88 in the front wall 81 of the regulating means 70, and a button 112 on which a pointer 113 is attached and can indicate the angular position of the button 112 on the scale 111. The latter also has a protrusion 114 designed to facilitate its rotation. The knob 112 is rotatably installed on the front wall 81 of the regulating means 70 through an inner, inwardly protruding bushing 115 which is inserted into an opening 89 in the front wall 81.

the button 112 can do this with the help of the key 128 to be connected to the regulating means 70, as how mentioned above, the key shaft 120 can rotate the disk 101.

You start the game with the engine-like noises by inserting the key 128 into the keyhole 127 of the button 112 and into the slot 126 of the Key shaft 120 is inserted.

The bar 106 falls off the Projection 99 'of the base plate 97, and the second contact finger 105 touches the resistance coil 96 (Figure 9). The initial contact of the second contact finger 105 with the resistance coil 96 ("IDLE" position) is from the lead wire 34- (Figure 10c) far from having a great length of resistance coil 96 on in the electrical circuit and low input voltage to electric motor 30. As a result, soft noises of a slow idling motor are produced 105 with the resistance coil 96 upright, the switched on in the electrical circuit (FIGS. 10d and 10e) As a result, the engine noise becomes more intense and corresponds to an engine running in overdrive at full cruising speed.
