Miniature light beacon for the exact parking of a car in a garage

Driving into a garage can cause problems, such as damage to the door and car, especially with a narrow door, as is often the case with automatic garage doors.

The invention makes problem-free parking possible. The operation of the device or "gadget" is based on the principle of parallactic observation with a light line consisting of 2 light sources located one behind the other with respect to the observer and having a height difference. The straight line through the light sources, or the axis of the miniature light line, indicates the desired driving route for the car. . In shipping, light lines with much larger dimensions are used to accurately navigate when entering a port. On the axis, the light sources are observed directly above each other; next to the axis they are skewed one above the other. The driver therefore receives continuous information when entering the garage. During this process, adjustments are always made by keeping the lights perpendicular to each other. If the lights are above each other on the left, then you are on the left of the axis; at the top right of each other the position of the car when entering the car is to the right of the axle. The eye is very sensitive to deviations from the vertical position. This is apparent from Figure 3, where the angle between the light sources, as observed by the driver, is plotted vertically against the angle, whereby the lights are no longer seen perpendicular to each other. The miniature light beacon also has a facility for stopping the car in the right position at the desired location. This criterion is achieved by a third light source, next to the rear light, for which there is a screen with a horizontal edge. As a result, the third light source eclipse when entering the garage until the correct stop location is reached. At this moment the driver sees 3 instead of 2 lights. The light sources are of the LED type. In the production model, 2 red and 1 yellow-colored LED was chosen. 30, but other combinations of colors are also possible.

Alternatively, the rear light is replaced by 2 pieces of identical light sources placed next to each other at the same height. On the light axis the driver sees an isosceles triangle standing upside down; a crooked triangle is observed next to the axis. The LED light sources are electrically connected in parallel 5 and connected via a series resistor to a standard adapter, which supplies approx. 6 Volt direct current, with an annual consumption of approx. 20 kWh. The aforementioned light configuration can be used in many ways in a device are processed. The miniature guide beacon is mounted against the wall of the garage, directly opposite the entrance, at a height of approx. H = 1 m. Above the driver's eye level; this is approximately 1.80 to 2.0 m. above the ground (see figure 2)

The distance between the front and rear LED is approx. A = 50 cm and can optionally be set variably. The tolerance when entering is 1 to 2 cm. compared to the garage door style. At a distance of 15 to 20 m from the aiming beacon, this already gives a good discriminating left / right criterion.

This can also be theoretically supported with figures 2 and 3.

The angle A between the lights of the miniature light line follows from the following formula: A = arc cosine x2 - a.x + h2.

V ((x - a) 2 + h2). (X2 + h2))

The vertical angle A found can then be translated in figure 3 into the horizontal angle B, wherein the lights are perceived as just not perpendicular to each other. The tolerance is then y = x..tg B perpendicular to the axis.

With regard to the technical implementation of the miniature light line or directional beacon, the basic principle is that it must be as simple as possible a device, consisting of standard materials and profile tubes and assembled with screw / nut connections. It must be possible to produce in a simple workshop in series production. On the basis of figure 1 with numbering, a production model is described in detail 1 '1 3.

Aluminum is used as the material. The corner line 1 of 53 cm. long, with dimensions 5 20x20x2 mm, ensures the distance between the light sources. On the front is a U-shaped converted plate 6, where a threaded end 8 adjusts between the upright edges perpendicular to the axis with rotary knob 7. This setting is very accurate and compensates for tolerances in other parameters, such as not exactly right-angled walls in a garage, etc. Mounting takes place against the rear wall using 10 of 4, a 90 degree angle piece (100x100x5 mm) of galvanized iron, which is directly attached to the side of the corner of the light beacon and forms part thereof. This makes it possible to mount practically up to ceiling height. The mounting plate 2 with dimensions 80x60x1 mm contains the electrical circuit, which is further processed in the terminal block 5. The LED light sources are also attached to this. The eclipse angle line 3 15 with dimensions 15x15x1 mm, is located at 2 to 3 cm from the eccentric light source, so the traffic light. The eclipse corner line also prevents reflective light in the metal of the light line structure, and thus has a dual function.

The metal of the light beacon also functions as an electrical conductor.

A series resistance of 100 Ohm is applied. The length of the corner line, and therefore the distance between front and rear light, can be made variable by making 2 corner lines of it that slide over each other and are fixed by means of a hose clamp .
