Abstract

A rebound-preventing device for transmitting motion to the rotatable turnstile 1 of a theft-prevention door comprising a first reduction gear 6 and a second reduction gear 10, which can be individually reversed but which as a unit are irreversible transmitting in series the drive torque produced by motor 13 to turnstile 1. Reduction gears 6, 10 are preferably of the endless screw/helicoidal wheel type and have a transmission ratio of between 1:15 and 1:25. Motor 13 is preferably of the direct current type and which senses forces applied to turnstile 1 allowing the latter to increase or decrease its speed of rotation controlled within minimum and maximum limits by a tachymetric dynamo 14 fitted to the motor. <IMAGE>
