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).

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
