Description

[Detailed description of the invention] The invention relates to a device according to claim 1).

When leaving the vehicle, the driver may not be able to tell whether the anti-theft alarm system has been activated or not.

This is especially the case in the dark when even the locked state of the door closing device cannot be tested without the attached handle of the door opener.

For this reason, an illuminated diode, which is visible from the outside of the vehicle, has already been installed near the locking button of the known motor vehicle closing device on the inside of the door (see Driving Guide for the 1983 Citroën CX Diesel, page 2).

Similarly, in 1985, Funkschau (Funksc)
4. From pages 70 to 73, it is known to signal the status of a connected motor vehicle alarm system by means of a flashing diode.

However, these lighting diodes always require space to be installed on the upper side of the inside panel of the door. Special holding or fixing elements must likewise be provided for the lighting diodes to balance the unavoidable tolerances between the door inner panel and its covering. Furthermore, in the case of motor vehicle alarm systems according to the Funkschau type, the problem arises that the power consumption of the lighting diodes is relatively high, due to the lighting diodes themselves and the necessary multipliers.

Therefore, an object of the present invention is to provide a device according to claim 1), which can be installed in the inner side plate of an automobile door without requiring a space, and which can be installed at an installation point related to a closing device of a car, and which can be installed at a place where silk is inserted. The objective is to provide a product that is independent of manufacturing engineering tolerances in the area of

This object is achieved by the features of claim 1).

The advantages of this invention lie primarily in the following points. The advantage is that the device can be integrated into a ready-made element of a motor vehicle door and therefore does not require additional installation space in the inner door panel. The installation point is clearly related to the vehicle's closing device. By pulsing the indicator element with long pulse intervals compared to the blinking pulses, a reduction in energy consumption is achieved on the one hand, and on the other hand, the elimination of a multiplier is realized.

The figures showing examples will be described in more detail.

In FIG. 1, reference numeral 1 indicates a locking button. As is well known, the locking button 1 has a screw hole 2 at its lower end, by means of which the locking button 1 is screwed onto a locking rod 3 of a closing device (not shown) of a motor vehicle. At least the end of the locking button opposite the end with the screw hole 2 is made of a translucent material 4, and this part is provided with an electro-optical transducer 5 arranged or cast on the locking button 1, e.g. Lighting diode (
It can be illuminated by LED.

L E D 5 is connected to the energy supply 8 via a set of electrical conductors 6 . 7 led out from the bottom of the locking button 1 . This energy supply 8 can be placed in a corresponding mounting hole in the interior of the motor vehicle door via a fastening port 9, which can be cast onto the housing, for example (not shown). The energy supply 8 also has an electric plug IO, by means of which the energy supply 8 can be connected to the motor vehicle energy supply via a switching contact (not shown) of a locking device or an alarm device. In this example, when the closing device is locked or the alarm device is connected to the active state, this switching contact is closed and the energy supply 8 is therefore supplied with operating current.

FIG. 2 is a top view of the entire device.

FIG. 3 shows the principle wiring diagram of this device. The energy supply unit 8 replaces the direct current voltage (energy supply voltage Ub) which is known per se and which is in contact with the human power unit 10 with a rectangular pulse signal of a determined pulse width Tb (blinking pulse B) and a pulse interval Tp. For this purpose, for example, an astable multi-vibration brake with low current consumption can be used.

A pulse diagram relating to this is shown in FIG. In this case, the pulse width of the blinking pulse B is the time length Tb
is chosen to match the input of the LED, ie to be able to dispense with a multiplier, for example. Thus, no additional power losses occur in this type of matching element.

However, the pulse width 'b and the pulse interval Tp are arranged in such a way that the blinking pulses are clearly visible and have sufficient repeatability. Typical values are, for example, for the pulse width Tb of the blinking pulse B
5m5ec, and the pulse interval 'rp is 15sec. Of course, the blinking pulse B can be broken down into a large number of pulses.

FIG. 5 shows the lock button 11 for wireless energy supply of the LED 12 provided inside the lock button 11. For this purpose, a coil (secondary coil 14) is attached to a locking rod (not shown) at the lower end of the locking button 11 in order to screw the locking button 11 into the area of the screw hole 13. (injected into the coil), and the LED 12 is electrically connected to this coil.

FIG. 6 shows a coil support 15 with an energy supply 16 essentially the same as the energy supply 8 of FIG. These parts are shown in plan view in FIG. The coil support 15 and the energy supply 16 are interconnected by a set of conductors 17,18. The coil support can be placed on the inside of the motor vehicle door by means of the hole 19 and the support element 20, and the energy supply 16 can be placed by means of the fixing bolt 21. The coil support has a central bore 22 into which the locking button 11 is axially guided.

FIG. 8 shows B of the coil support 15 with a central hole 22 and a cast primary coil 23 connected to a set of conductors 17, 18 and serving to energize the LED 12 in the locking button 11.
-B direction cross section is shown.

FIG. 9 is an electrical principle connection diagram of the apparatus shown in FIGS. 5 to 8. At the fixed position of the locking button 11 relative to the coil support 15, shown in the subsequent FIG. The transformer between the secondary coil 14 and the secondary coil 14 provides an operational coupling (inductive coupling). The pulse generated from the astable multi-by-break (not shown) of the energy supply 16 shown in FIG. 4 is then transmitted from the primary coil 23 to the secondary coil 14 to illuminate the LED 12.

is fixed (welded). Coil support 15 and covering part 2
8 is screwed to the holding angle by means of a screw 29 and a plate nut 31 inserted through a hole 30 in the holding angle 27. The coil support is braced against the door inner panel 2G by means of a bearing element 20. The locking button 11 is guided by an elastic sleeve 32 and held in position relative to the coil support and the opening in the sheathing 33. In this case, the sleeve 32 in particular makes it possible to balance the manufacturing and installation tolerances between the door inner panel 26 and the cladding 28.

In the retracted state of the locking button 11, which shows the locked state of the automobile door closing device shown in FIG.
4 are in a mutually concentric position, so that there is good inductive coupling between these coils, so that the energy is partially transferred by the transformer from the coil 23 to the secondary coil 14 and the lighting diode 12 is applied. Can be diffused.

Thus, day and night, the vehicle doors are properly locked and the alarm system is connected to operate.

On the other hand, when the motor vehicle door is not locked, the locking button 11 clearly protrudes from the cover 28, as shown in FIG. It can be seen that the coils in the set are clearly shifted from each other. In this way, the primary coil 23
There is no longer any inductive coupling between the and the secondary coil 14 (
Or it becomes so weak that it is no longer sufficient to control LED)
. This has the advantage that, if the door is not locked, no optical relay signal is generated even in the event of a fault in the closing device or the alarm device (eg control of the energy supply 16). .

Comparing the configurations of the lock buttons in Figures 1 and 4, the 10th
As shown in Figure and Figure 11, only one plate-shaped LED
A transparent plastic part 34 allowing the transmission of 12 lights can also be inserted into the locking button 11, while the remaining part of the locking button is made of non-translucent material.

Electro-optical converter (LED 35
) shows another example of signal transmission in FIG.

The locking button 36 consists of three parts, namely a transparent part 37 and a threaded part 38, which is mounted on a locking bar 39 of a closing device (not shown). The transparent part 37 is clipped onto the threaded part 3B and is prevented from twisting by a protrusion 4.degree. which engages in a corresponding groove 41 in the threaded part 38.

The transparent part 37 is conically (or also spherically) hollow above the receiving space of the screw part 3 and is particularly reflective. A prism can be inserted here as well. In this way, the illumination 42 emanating from the LED 35 towards the illustrated retracted position of the locking button 36 is directed towards the conical surface 4.
3 and is visible against the textured or roughened surface 44 of the locking button 36.

The locking button 36 is further secured to the covering portion 4 by the rosette 45.
6 and the door inner side plate 47. LED
35 can for example be fixed to the door inner panel 47 (for example by studs 49) by means of a simple retaining member 48 which at least partially surrounds it. The LED can be supplied with current by a suitable energy supply member as shown in FIGS. 1-4.

Signaling can only occur in the illustrated position of the locking button 36. On the other hand, the lock button 3G is partially covered by the
6 (lower edge locking button 36 at the level of the lower edge of the rosette 45, non-locking door), the light path between the LED 35 and the striped surface 44 is interrupted.
