Description

The invention relates to the manufacture of toy vehicles, in particular floating toys, and can be used to make a toy submarine with an electric control circuit.

The purpose of the invention is to increase entertainment.

In FIG. 1 schematically shows the proposed toy, a side view in section; in FIG. 2 - the same, top view; in FIG. 3 is a control circuit diagram.

The toy contains a housing 1 (Fig. 1) with a bow 2, wheelhouse 3, depth wheels - two bow wheels 4 and two aft wheels 5 (Fig. 2), a rudder 6 and a propeller 7. A control unit is located in the bow of the body the movement of the boat 8, including two transistors 9 (Fig. 3), resistors 10 and 11, a diode 12 and a relay 13. The control unit is part of an electrical circuit including a depth gauge made in the form of two conductive rods 14, three electrical elements 15 and a start switch, consisting of a jumper 16 and contacts 17 to turn on the electric esky scheme. Conductive rods 14 are mounted vertically on

wheelhouse 3. An electric motor 18 (Fig. 1) is installed in the casing, connected with the i-th screw 7. Between the nose and the casing there is a rubber gasket 19 for sealing the internal cavity of the casing.

The work of the proposed toy is as follows.

Before starting the toy, the rudder 6 is set to a certain radius of curvature of the movement and the jumper 16 is inserted into the sockets of the contacts 17 start switches. The electric motor 10 starts to operate at nominal speed, with the uyum plus voltage of the elements 15 is supplied to the electric motor through the jumper 16 of the start switch, and the minus voltage passes through the make contacts of the relay 13.

When launching, the toy begins to gain speed and begins to dive using rudders of depth 4 and 5. The depth wheels are set at a certain angle (from the theory of hydrodynamics -Z1, which allows the toy to go diving at maximum speeds of the propeller 7. When the depth of immersion is reached, at which the conductive rods 14 mounted on the water are wetted

cutting 3, minus the voltage of the elements 15 is supplied to the base of one of the transistors 9. The signal from the depth gauge is amplified by transistors 9 and fed to the relay winding 13. The relay operates and opens its make contacts. In this case, the resistor 11 is disconnected, connected in series with the electric motor 18, which exits at low revolutions. The speed of the toy decreases and it begins to float.

Depending on the magnitude of the electrical resistance of resistor 11, the toy can be set to a different swimming mode. So, if the resistance is increased, the toy will go under water at 1 depth, which is determined by the height of the conductive rods installed on the wheelhouse and interacting with the surface of the hearth when diving a submarine (the so-called periscope depth), followed by diving. She will not be able to dive beyond this depth and therefore is not lost sight of.

Compared with the known floating toy means, the present invention increases the amusement of the toy due to the autonomy of controlling the boat in the surface and underwater position and the ability to observe its movement under water while limiting the depth of its immersion.
