Abstract: A drive control device for an electrically-driven extending and retracting antenna such as an antenna on an automobile including a motor-driven rotary plate which makes approximately one revolution during the time for complete extension or retraction and has attached, on one side, a disk-shaped conducting part with a small cut-out.

Abstract: An antenna rod, which is extendible and retractable, is moved up and down by a cable with a rack, and the cable is moved with rotation of a pinion gear. The rotational force of a DC motor is transferred to the pinion gear by a route of a worm, a worm wheel, gears, a damper gear, and a damper. The damper is a coil of resilient metal wire, and both ends of the coiled wire, respectively, engage stopping members, which are provided at the center portions of the damper gear and the pinion gear. When the pinion gear is at a standstill, the rotational energy of the damper gear is accumulated in the damper. The motor is rotated under control of a control circuit in response to the operation of a switch. The drive current for the motor is shut off by a detecting signal from a lock detector during the course of accumulating the rotational energy by the damper. The lead angle of the teeth of the worm is large so that the rotational energy stored in the damper is transferred to the motor.

This is accomplished by a rod-shaped transmitting and receiving main antenna element within an antenna retaining mechanism so designed that the antenna element is free to slide in and out of the case of the radiotelephone. This case also houses a sub-antenna element which is in constant electrical contact with the antenna retaining mechanism. Conductive components in the elements provide the switching function, and one of them, a conductive tube, is constantly connected to the transmitter-receiver set in the case so that there is no deterioration of the characteristics of the main antenna element.

Thus, the antenna element functions even when it is located inside of the case. Moreover, an auxiliary antenna element is connected to the antenna element when the latter is located inside the case. The inductive reactance component of the auxiliary antenna element compensates for deterioration of the Standing Wave Ratio caused by the increased stray capacity resulting from the antenna element being located of inside the case.

The control comprises control means responsive to the extend and retract signals to activate the drive means toward, respectively, fully extended and retracted antenna positions and further comprises control means responsive to the ignition switch in its start position to deactivate the drive means at least in the extend direction and for at least a predetermined period of time deemed sufficient for engine starting, whereby reversal of antenna extension during engine starting is prevented.

Abstract: A power antenna control for a motor vehicle comprises a Hall effect device responsive to motor armature rotation to generate pulses for equal predetermined increments of antenna travel. These pulses are applied to both position and stall counters. In extension, the antenna drive is stopped when the position counter reaches a number corresponding to a predetermined extended position, which may be full extension or some lesser extension. In retraction, the stall counter is used with a clock to indicate stall which, when detected, causes the antenna drive to be stopped. Automatic current limiting for drive torque limitation during stall is activated only when the position counter indicates a limited position range near full retraction. Further during retraction, if the antenna is stopped within a small position range of full rectraction, it is reset to a count indicating full retraction. The system eliminates the need for hard stall sensing reaction switches and thus reduces antenna drive cable fatigue.
