ABSTRACT:
The invention relates to a safety device for moving handrails consisting of a stop (5), arranged at the entrance of the handrail (1) assembled on a fixed railing (3) finishing the handrail, the stop (5) being connected to a rod (7) which can move longitudinally and is retractable against a spring (9), the device comprising a hinged outer lid (15) having locking pawls (19) for an inner lid (18), such that the outer lid (15) automatically tends to the open position due to the effect of the springs (17) affecting the hinge (16) when the stop (5) is retracted and the lock (10) of the latter are released, whereas the inner lid (18), upon being released, also tends to the open position by simple gravity. In this way when a user does not let go of the handrail (1) when it penetrates the railing (3), he or she drives the stop (5) with his or her hand and the lids (15) and (18) are automatically opened, preventing injury to the hand of the user and causing the stop of the handrail through a microswitch (23).
