Description

The present invention relates to a device for signaling that a car and other self-propelled carts exceed a set speed, in which the speed indicator is provided with light color signals and a series of electrical contacts corresponding to the speed limits for activating the signal device. According to the invention, a switch is used in the device, the electrical contacts of which are connected to the contacts of the speed indicator and which is provided with a brush installed in the audio signal circuit at a certain maximum speed and light signal signal for a certain color corresponding to the same speed.

In FIG. 1 shows a device diagram; FIG. 2 switch this device.

The device consists of a speedometer 1, a switch 14, a sound signal (not shown in the drawings) and a light signal 15/16. Speedometer 1 is equipped with several contacts b, 7, 8, 9, 10, 11 of the signal electric circuit, respectively, permissible limit speeds, the arrow of which slides along these contacts as the speed increases. Contacts b, 7, 8, 9, 10, 11

electrically connected respectively to the contacts Sj, 7i, 81, 9i, lOi, ll of the switch 14, the brush of which when turning the axis 13 can be set to one of these contacts, respectively, the permissible limit speed of the vehicle.

The pins 6i-111 of the switch 14 are mounted on a plate 22 of insulating material and arranged around a circle, through the center of which passes an axis 13 with a brush 20 mounted on it, which slides pe to the contacts 6i-111 as the axis rotates. Through a different circle, drawn on the same plate 22 from the same center, through holes 23 are drilled. Each hole 23 lies between two adjacent switch contacts. An axis 13 of a metal disk 24 with tight pins 25 secured on it is loosely mounted on the axis 13. Closely to the disk 24, a spiral spring 26 is mounted on the axis 13, which tends to press it into the plate 22, but this is prevented by a latch 27.

If the car goes in an area where a certain speed is set, for example 40 km per hour, the driver, using the handle 12, sets the switch 14 so that the brush 24 is at a certain contact according to this speed. In this case, the axis 13 is rotated together with the disc 15 fixed on it, painted in different colors according to permissible speeds, to a certain position so that a color corresponding to the speed at which the brush 20 is installed is opposite to the illuminated light bulb 17 of cutout 16 Switch 14 for a speed lower than it has the right to translate, because in this case, at a lower speed than permissible, the alarm will start to operate and the car will be stopped. Rather, he is interested in putting the switch at a higher speed than allowed in the area. But he cannot do this, because, by switching the switch, he simultaneously changes the color visible in the slot 16 of the disk 15, therefore, if a car with a red sign is noticed, in an area where it is allowed to drive only with a green sign This machine will be stopped. If the car exceeds the set speed, the speedometer needle 1 closes the electromagnet 3 circuit, which, pulling the measles, will release the load 30. The latter, under the action of its spring, will fall on the latch 27 and release the spring of the lever 29, which holds the disc 24. 26, is pressed against the plate 22, and the pins 25 will enter the holes 23 and will not allow the transfer of the brush 20 to another contact. At the same time, the contacts 28 of the signal circuit will be closed and the alarm sound device will work. Consequently, switch 14 is set so that if the alarm has started to act, then it cannot be switched to a position corresponding to a lower speed until the signal device has been stopped. This fixture fixes, thus, what speed was surpassed at the moment of the beginning of the signal fixture. To stop the signal device, push the lever 29, which brings the disk 24 to its original position, turns off the current from the circuit of the signal device and lifts the load 30 until it is gripped by the electromagnet 3.

Impossibility of abuse is achieved by the fact that the wires and the flexible shaft are enclosed in metal tubes, and the responsible parts of the device are enclosed in sealed cases.

Subject of the invention.

Claims (2)

1. A device for signaling that a car and other self-propelled carts exceed a set speed using a speed indicator equipped with several electrical contacts corresponding to the speed limit and light color signals corresponding to these speed limits, characterized in that the contacts 6i, 7i, 81 , 111, the speed indicator is connected to the corresponding plates 6i, 7i, 81, 111 of the switch 14, which serves to install the brush 20 in the sound signal circuit at a certain speed limit And light signal 15,16 for a certain color corresponding to a given limit speed. 2. In the device of claim 1, the application is in a switch 14, to prevent it from shifting to a lower speed after transmitting a signal that the set speed is exceeded, freely mounted on the axis 13 of the disk 24, which is under the action of the spring 26 and carries pins 25 entering in order to prevent the movement of the brush 20 into the holes 23 of the switch when the latch 27 is dropped by the load 30 released by the electromagnet 3 when the car reaches the set speed.
