Adjustable display device, especially for parking time control M

in motor vehicles

The invention relates to a simple and practical design an adjustable display device, especially for parking time control in motor vehicles, from a housing with one or preferably two symmetrically arranged reading windows on two opposite one another Pages behind which the ad appears.

The purpose of the invention is to create such a display device with simple and safe functionality and convenient operation

by means of a single knob and with facilities for a JQ

easy attachment.

Such a display device is also characterized according to the invention through one that carries the displays and at both ends film or strips attached to each coil inside the housing, which is in engagement with a toothed ring on each of the two coils and can be operated from the outside with a rotary knob Ritzels while passing behind the reading windows on the one or

1310. P32.12D.3 - BIl / KW / ek

another bobbin can be wound.

The attached drawing shows an example of an embodiment of the display device designed according to the invention, in which: ^FIG

Fig. 1: a perspective overall view, Fig. 2: a plan view with the housing cover removed, Fig. 3: a! Section along the line 3-3 according to Fig. 2 and Fig. 4

and FIG. 5: a perspective view of parts of fastening devices.

According to this, the display device consists of a cuboid housing 1, which is closed by means of a cover 2, for example. On two opposite sides la and Ib of the housing 1, two reading windows Ic and Id are arranged symmetrically.

The display lettering is carried by the two sides of a film or strip 3, which at both ends on two Coils 4 and 5 is attached, which are mounted, for example, on fixed axes on the housing bottom. The order of the display labels, if the clock is used for parking time control, for example, time information is on the two sides of the film or strip applied in reverse order. This film or strip can alternately be wound onto each of the two reels 4 and 5, and by means of a gear wheel or pinion 6 which is seated in a rotationally fixed manner on the axis of a rotary knob 11. This pinion 6 is between the two coils 4 and 5 and is in engagement with them via a ring gear 4a and 5a. This ring gear 4a and 5a on each of the two coils 4 and 5 has a small radial width

109820/0129

while the rest of the outer circumference of the coils is smooth.

To get the film or strip straight behind the reading windows Ic and I'd be able to pass by, 'there are pulleys in the four corners of the housing 7,8,9 and 10 arranged. These pulleys 7 to 10 are rotatably seated on axes Ie, which are fixed to the housing base are processed, and conveniently at the same time Forming the housing from plastic.

These axes of rotation Ie of the pulleys can also be advantageous Way simultaneously serve for centering and / or fastening of the cover 2, which for this purpose with recesses or others suitable facilities are provided.

Fig. 2 shows an example guide of the film or strip This is attached to the coil 4 and runs from here over the UmlenkroUe 7 behind the two reading windows Ic and Id of the one Housing side Ib over to the opposite UmlenkroUe 9, then diagonally through the housing to the pulley 8, from here behind the reading windows Ic and Id of the other side of the housing la and Via an opposite deflecting roller 10 to the other coil In this way, the film or strip can be wound onto one of the two reels 4 or 5 in a certain length.

The display device designed according to the invention is also included Fastening devices equipped, making it visible from the outside, for example on the dashboard of a motor vehicle can be attached.

For this purpose, there are two parallel, angled profiles on the underside of the housing Slide rails 12 and 12a arranged between which a

109820/0129

Fastening part can be inserted.

Such fastening parts can consist of a plate 13, for example according to FIG. 4, which is firmly connected to a magnet 14 is. In this case, the display device can be placed in a simple manner on the top of a motor vehicle dashboard, if this has an approximately horizontal surface.

According to FIG. 5, the fastening device can also consist of a simple one Plate 15 are made, which are equipped with retaining clips 15a and 15b is. The. ^ E retaining clips are then in corresponding openings or clamps used on the dashboard of the vehicle or another surface.

As already mentioned, the trained according to the invention Display device are preferably used for checking the parking time in motor vehicles, but are also used for other purposes possible, whereby adjustable displays should be made visible in the form of numbers or letters.
