SU34351A1 - Electric flashlight device - Google Patents

Description

Devices are already known for automatically switching on electric flash lighting at a certain point in time and turning it off after a certain period of time. In particular, such devices are known that are driven by a clockwork rotating a disk, on the periphery of which pins or the like are installed at certain places, which act on switches located near this disk that control the switching on or off of electric circuits.

The present invention relates to such devices and is intended primarily for flashing lights of buoys and coastal signs. It allows the automatic switching on and off of the flashing light at certain, adjustable on request, moments of the day. Thus, the proposed device provides, for example, the ability to set the beginning of the ignition at 6 pm and off at 6 am. Such an installation may remain unchanged for the duration of the battery life — from one shift to another, and then, depending on the season, change according to the average duration for the next period.

In FIG. 1 shows a front view of the device according to the invention ;, FIG. 2 is a top view of a part of it; FIG. 3 and 4 - switching mechanism in two different positions.

On board 7, the base 2 is fixed, on which is located the mechanism that causes the rotation of the disk 3 with twenty-four-hour divisions on it. This mechanism consists of an electromagnetic relay 5 placed on a separate frame 4. The electromagnets of this relay are supplied with direct current and in the usual way, alternately switching them to vibrate measur 6, which entails switching on and off the lamp and, hence its blinking.

To turn on the light at a certain moment of the day, for example, at 7 o'clock in the evening (Fig. 3) and turn it off, for example, at 2 am, disk 3 has twenty-four pairs of holes into which screws can be screwed to attach 8 n 9 cams (Fig. 3 and 4), located on opposite sides of the disk 3. These cams, the passage when the disk 3 is rotated past the lever J3-J4y, respectively, turn on and off switch 7.

To do this, on the rack / 7 between the walls of JO (Figs. 1 and 2) on axis 72 is fixed,

a double-shouldered lever 13-14, made in the form of a rocker, whose shoulders 13 and 14 are located in different planes. On the same axis 12, a toothed segment 15 is attached, which engages with gear 16, on the axis of which a lever 77 is fixed; The end of the latter is provided with a pin 18,; on which the spiral spring 20 is fitted with one of its ends, being in the tension of Fig. 3 in a tensioned state. The shoulder 13 of the double-arm lever 13-14 is connected with the spring 21 with the knife switch 7.

The operation of the proposed device is as follows.

When the cam 8 mounted on one side of the disk 3 fits the shoulder / J of the two shoulders lever 13-14, the knife switch 7 is turned off, and the spring 20, being in the tensioned condition to the left of the axis 16, keeps it securely in the off position: nii. Passing the shoulder 13, the cam 8 presses it and closes the cutter; while the segment 75 rotates the gear 16, and, transferring the spring 20 through the middle position, brings it to another extreme position shown in FIG. 3, thus fixing the included position of the ruler 7. With further movement, the cam 8 Passes past the shoulder 14 of the two-armed lever 13-14, lying in a different plane, and therefore does not touch it.

Upon further rotation of the disk 3: a cam I located on the other side of the disk 3 passes by the two shoulders of the shaft 13-14, which, when passing by the shoulder 14 (Fig. 3), deflects it to the position of FIG. 4, open the switch 7; at the same time, segment 15 rotates gear 16 and translates spring 20 from the rightmost position and (fig. 3) to the leftmost position (fig. 4), fixing the switch in the off position, with spring 27

provides tear-off action of the knife switch 7.

In order for the disk 3 to make one revolution at twenty-four hours correctly, a stable frequency of the core 6 oscillations is necessary, for which a constant voltage supplying the relay current is required. This can be ensured by the inclusion of a barreter lamp fc in the circuit of the relay with an iron filament).

The subject matter of the invention.

Claims (2)

1. A device for electric flashing lighting using, for periodically closing and opening the circuit, an electric relay turned on at a certain point in time and turned off after a certain period of time by means of a disc rotating from a clock mechanism on which protrusions are installed, which serve to act on a rotary lever a switch characterized in that said rotary lever of the switch is designed as a rocker arm, the shoulders 13, 14 of which are in different planes for the purpose of so that the interaction of the shoulder 13 with the protrusion 8, installed on one side of the rotating disk, closes the circuit, and the interaction of the shoulder 14 with the protrusion 9, installed on the other side of the disk, turns off this circuit. 2. In the device according to claim 1, use a toothed segment 75 fixed on the axis 12 of the lever 13-14 and coupled with gear 16, which serves to transfer the tensioned spring 20 from one extreme position to another, in order to ensure a reliable position of the lever 13-14 and a knife switch in the switched on or switched off position.
