Description

The Kriindiing concerns a motor vehicle Radio.mten ■ only high-frequency amplifiers, whose one-piece type nnenstali iniiei half of the body at) gi: deck η space arranged and. in a Huchse or '. IgI.

guided through an opening in the body panel the activation and deactivation of the radio is controlled and can be extended and retracted by motor.

Knftwagen-Radutantünnen of this kind are for example by PT-AS 1132 992 and LISPS 2 553 bl I known- In the lalle of the radio antenna after the DI-AS I 132 992 is provided, as well as the actual antenna rod, a Sehachia tube encompassing the antenna rod is extended. Along the Antennensijbes ersirecki a threaded spindle, which requires significant driving forces to achieve the Antenna rod moving spindle nut to move along the spindle. Ks are not just the frictional forces between the threaded spindle and spindle nut, but rather the frictional forces of the other the spindle nut in a guide tube, which prevents the threaded nut from rotating at the same time;

In the case of the embodiment according to LIS-PS 2 ^r >"ii h!! There is a toothed rack as an'- .; ⁿ nc" stab Anw enduiiL ¹ . So a very useful component.

If the radio is switched on, the keypad 28 does not also turn on with the hearing result. that according to I ι g. J the ground connection 35 is connected to the contact? 2 via the visual ball 3h and the Haticrieansi hliill 24 via the Sch.iitbugcl 17 to the contact i4 v.in! This closes the circuit for the motor I i and it starts up. By means of the Umlaulbiindaiilneb the carriage 5 is moved up on the slide rail h and thereby leads the antenna rod I out upwards. Tüne Zwisehcnsi osition is illustrated in FIG. I When extending, the same applies in FIG. 4 shown circuit diagram: because with ι learn the first start-up of the motor Π and with the first axial displacement of the antenna sensor I, the spring clip 17 is able to shift the slide rail 6 into the middle position, that is to say shift it upwards by the leather wcg so that the switching load 22 is released. With this release, the l.nd sehalter 24 switches over. however, still the power supply to the motor I? via contact 14 is retained.

When the antenna rod I reaches the upper hand position, the conductive contact between the antenna rod I and the high-frequency amplifier 27 is established by means of the contact body 25 on the antenna rod I and the contact spring 26. At the same time, however, the slide 5 also ran up against the stop 18 of the slide rail 6 and shifts the slide rail 6 axially upwards. with which a Aufwärisvcrlagening ties .Schalthakens 20 is connected. so that this presses the switching load 21 of the hand-held sounder 21, sunbathes the motor 1J and shuts down the high-frequency amplifier 27 via the contact 40, as it is from the Γ i g. ^r > is removable. which illustrates this .sound position. The switching processes when the antenna rod I is moved to illustrate FIG. b and 7. If the radio is switched off, leave the relay 28 lo ··. and switches. so that the circuit diagram Je and 57 again show the position according to I 'ig. 2 occupy Since the hand switch 24 has meanwhile made a conductive connection with the contact 41, be the timschallen of the relay 28 when the radio is turned off a start of the motor 13 in the opposite direction, so that the shoulders 5 is moved down on tier slide rail 6 . During this downward movement, the sound hook 20 also moves back into the middle position, since the side rail 6 is pressed into the middle position by means of the spring clip 16. The sound button 21 is thus released and takes the position shown in FIG. 2 a. The corresponding Shah picture is shown in FIG. 7. This Fig. also makes it clear that the pulling of the antenna rod I is associated with a detachment of the contact body 25 from the contact spring 26. so that the connection / between antenna rod 1 and high-frequency amplifier 27 is interrupted. Likewise, the high-frequency amplifier 27 is switched off via the contact 40. When the antenna rod 1 reaches the lower forward position, the slide 5 hits the stop 19 and thus also shifts the switch hook 20 downwards. Hs so that the switch button 22 of the hand switch 24 is pressed, and the Molor 13 emits sound. This again shows the noise level according to FIG. 2 reached.

The connection of the threaded bushing 43 to the housing 42 is established by the nuts 49 and 50, between which the upper wall of the housing 42 is clamped I. di <. Schlillenschiene 6 extending parallel to this, the parallel extending slide 6 Belt drive with roller wheels 8 and 9 and the motor 13 with the transmission 10 to 12 in the smallest of spaces, these parts differ from the schematic representation according to FIG. I not arranged next to one another but partly behind one another. as shown in FIG. 8 and ^c > make it clear. For reasons of space, the arrangement of the sound hook 20 in connection with the hand switches 23 and 24 also differs from the arrangement according to FIG. I from. Otherwise, tier corresponds to the structure according to FIGS. 8 and 9 according to FIG. I.

While the upper part of the housing 42 can be fastened to the body panel 44 by means of the threaded bushing 4], a clamp labeled 51 is used to fix the lower part. Provided in the housing 42 at the lower edge of the same is a ventilation hole 52 which ensures that cooling air can pass behind. The housing can, as shown in FIG. 4 shows / be in large parts, namely consisting of a shell-shaped body with a cover 53, the shell-shaped body and the cover 53 being by sicr. may be interconnected transversely by extending screws 54; Corresponding through holes for further screws 54 are denoted by 55 and 56 FIG. 9 also shows how the IJmlcnkräder! and 9 as well as the worm wheel 11 are fixed to the housing 42 by means of stationary bearing blocks 8, such as the high-frequency coaxial cable 31 and the radio connection 30 and the battery connection 29 reach outward from the housing 42. According to I- i g. 8, the Antricbsor gane for the antenna rod I in the lower part of the Ge housing 42, while the relay Z is above it and the high-frequency amplifier 27 is in the upper part of the housing 42. Accordingly, the housing 42 is kept very narrow and extends along the carriage section 6 parallel to that of the antenna slab 1. and outward movement within the housing 42 executes.
