Safety device for moving handrails

A safety device for moving handrails such as those used in transport systems comprising mechanical stairs and walkways, wherein said handrail, at one exit end of the handrail, comprises a plurality of moving handgrips which can move on a modular guide covered by them, said moving handgrips penetrating at their exit end inside a fixed and hollow railing, the railing of which has an opening, the device comprising:

• a stop:
• located in correspondence with the opening;
• retractable against the tension of at least one spring;
• wherein the device comprises:
• a lower support structure forming part of the railing itself, comprising:
• a front plate at the upper end of which there is arranged at least one retaining guide and a rear plate, said plates being connected by a plurality of bars perpendicular thereto
• a lowerable body with respect to said support structure according to a rotating shaft perpendicular to the forward direction of the moving handgrips, said rotating shaft being located in the rear plate of the support structure, the lowerable body of which comprises:
• a guiding rod integral with stop to which a runner is joined in an integral manner, which runner has a roller which can move in a direction parallel to the forward direction of the moving handgrips on the guide when the stop is acted upon a driving element of the lowerable body, one of the ends of which is connected with the possibility of rotation to the support structure and the other end of which is connected with the possibility of rotation to the lowerable body such that when the retractable stop is pushed by the hand of the user, the movement is transmitted by the guiding rod moving the runner which is released from the guide, the lowerable body being lowered due to the effect of the driving element.
