DE19629512A1 - Self-activating warning triangle for motor vehicle - Google Patents

Abstract

The warning triangle includes a flash function pulsing in adjustable intervals, and comprises low-voltage light bulbs arranged behind a magnifying arrangement on waterproof encapsulated, anti-glare reflector surface area in the equal- length limbs of the triangle. An adjustable photo-sensitive cell is installed in the lower, front limb of the warning triangle, which reacts to an amount of light incident on the cell, and activates a circuit loop of the control electronics. Photovoltaic surface areas are installed on the rear side of the limbs of the triangle, which transform the daylight into low-voltage current, and which recharge installed batteries over a charger circuit arrangement. A battery pack for the power supply of the warning triangle is arranged in the lower, front limb of the warning triangle. This battery pack can be exchanged, and can be recharged through the photovoltaic surface areas or via the on-board supply unit (of the vehicle).

Description

Ambient light-dependent, self-activating, warning triangle with at intervals pulsating flashing function.

Optionally in continuous lighting function, interval function or self-activating and can be switched off.

After placing the warning triangle over the magnetic switch of the Main circuit has been armed, can now be set to position 1 of the Switch to the automatic function. With this function The ambient light is recorded via an integrated photo sensor and at If the value falls below a set light value according to LUX, this begins Warning triangle flashing at 2 second intervals.

If the set lux value is exceeded for more than 1 minute, it turns out the warning triangle automatically switches back to daytime operation, d. H. it practices that normal function of an unlit, reflective warning triangle. At circuit 2 of the switch, the pulsing at intervals is manual Illuminated function switched.  

With circuit 3 of the switch, the pulsing in intervals is manually Illuminated function switched off.

After using the warning triangle, it is folded up again during this process the magnet switches off the main network.

The warning triangle can now be reinserted into the base plate.

Depending on the type and design, the vehicle's electrical system is now used Battery pack of the warning triangle recharged.

Achieved advantages

Compared to conventional warning triangles, this warning triangle offers the decisive advantage that it is independent, permanent ambient light recorded and automatically falls below when an adjustable LUX value is undershot a flashing flashing function switches at intervals. The warning triangle is therefore already visible at a distance of at least 500 meters and can be a highly visible warning function even in confusing situations exercise. A normal warning triangle is at dusk, fog, rain, night or snow is often very late or difficult to see.

This is eliminated with the new warning triangle.

Driving traffic is already from afar on the breakdown vehicle attentive and can react faster.

If the ambient light is the safety value, which with the photosensor is detected, exceeds longer than 1 minute, the warning triangle automatically switches to normal operation.

The photo voltag is also built into the warning triangle area Power supply additionally recharged during normal daily operation.

However, the warning triangle can only be used without this photovoltaic unit Battery operated and additionally via the charging function of the Electrical system are recharged.

Claims (2)

Ambient light-dependent, self-activating warning triangle, with flashing flashing function at adjustable intervals
characterized,
that in the triangle legs of the same length, in a watertight encapsulated, glare-free reflector surface, low-voltage bulbs are embedded behind a magnifying glass, which, in addition to the incident light from the front, generate their own flashing light, which is emitted to the outside, in front.
A photosensitive cell is installed in the lower, front leg of the warning triangle, which is adjustable and, depending on the lux number of light, reacts to the photosensitive cell and activates the circuit to the control electronics.
On the back of the triangle legs, there are photovoltaic surfaces that convert daylight into low-voltage current and can recharge the built-in batteries via charging electronics.
A battery pack for powering the warning triangle is located in the lower, front leg of the warning triangle. This battery pack can be replaced, recharged via a photovoltaic reaction surface or recharged by means of an on-board supply unit, which is used to hold the warning triangle when folded. This mounting base plate for the warning triangle contains a complete cable set and a control relay for the automatic charging system with overload protection. A magnetic switch is integrated in the lower leg of the warning triangle, which activates the main circuit from the battery unit to the photosensorig switching module, the photovoltaic and the low-voltage bulbs, when the warning triangle is set up, or deactivated when the warning triangle is closed.
There is a main switch on the lower, front leg of the warning triangle.
This main switch has three functions:

• 1. Switch on the permanent pulsing light function
• 2. Switch off the permanent pulsing light function
• 3. Activate the self-activating, lux-dependent, pulsating light function

The metal weight for the stability of the warning triangle is located below the entire unit of the warning triangle in the base plate and has four fold-out metal feet with rubber knobs on the front edge Stand fixation.
