Description

1 TARIFF FOLDABLE RAILING FOR INADEQUATE SHAFT TOPS IN ELEVATORS. Technical Field to Which the Invention Relates This invention is suitable for elevator shafts with insufficient shaft clearance, specifically in cabin roofs. a foldable 5 used to ensure the safety of maintenance and repair personnel It relates to safety railing systems. State of the Art Maintenance, repair, or rescue operations performed on the elevator cabin roof in elevator systems. to prevent personnel from falling into the elevator shaft during operations Guardrails with safety barriers are used. In standard elevator shafts, these 10 Guardrails are structures fixed to the cabin ceiling and remaining permanently in an upright position. However, in modern architecture or in the modernization of old buildings, the elevator shaft The distance between the top level and the shaft ceiling (shaft top space or final floor) (height) may fall below the standards. This is called "insufficient wellhead clearance". In that case, when the cabin reaches the top floor, a standard fixed handrail attaches to the well ceiling at 15 It can damage both the elevator system and the railing itself by colliding with it. Various methods have been developed within the current state of the technology to solve this problem. One commonly used method is "attachable" type railings. In this method, When maintenance personnel climb onto the cabin ceiling, they manually assemble the handrail sections. It disassembles it and takes it apart again when the job is done. This process involves dealing with multiple parts. 20 It is time-consuming, not ergonomic, and there is a risk of parts getting lost or falling into the well. It carries a risk. In addition, improper installation can create security vulnerabilities. Another well-known method is "horizontal lifting and lowering" systems. In these systems... The railing is raised and lowered horizontally around a hinge. However, these systems... They generally have complex mechanisms, are difficult to install, and are mobile 25 Vibration during normal elevator operation due to parts loosening over time. and has the potential to produce noise. The key mechanisms of these systems are also often It can be insufficient and far from providing complete security. 2 In conclusion, current solutions require long processing times and are ergonomic. its lack of potential security vulnerabilities and disadvantages such as noise Having it provides a more practical, secure and user-friendly solution in the relevant technical field. This has made its development necessary. Brief Description and Objectives of the Invention 5 The main purpose of this invention is to improve the technology in elevators with insufficient shaft clearance. Eliminating the disadvantages of its known form; safe, easy to assemble and use. The goal is to provide an easy, ergonomic, foldable railing system. Another purpose of the invention is to enable maintenance personnel to install it alone, quickly and with minimal effort. The goal is to increase work efficiency by offering a security system that can be turned off. 10 Another objective of the invention is to electronically control the open and closed positions of the railing. by ensuring that it is inspected, the elevator is put into maintenance mode before the handrail is fully opened, A safety mechanism that prevents it from switching to normal operating mode until it is completely shut down. The goal is to create an interlocking system. This will prevent human error. The aim is to prevent potential workplace accidents. 15 Another purpose of the invention is to minimize the amount of light emanating from the cabin ceiling when not in use. The goal is to provide a space-saving, robust, and vibration-free structure.

It is designed to ensure the safety of maintenance personnel in elevators. The system is In its basic form; at least one fixing foot (20) mounted on the ceiling of the elevator cabin, The handrail panels, which are attached to the legs in a pivot manner and are foldable, have the panel in the open position. at least one fixing arm (50) that secures and at least one 15 that controls the position of the system It consists of electronic control contacts (60). The system is installed by drilling holes in the elevator cabin ceiling at appropriate locations. It starts. The fixing feet (20), which are the main support elements of the system, are inserted into these holes. It is assembled. Fixing feet (20), rear handrail panel (30) and side handrail It forms an axis for the panel (40) to rotate around itself (pivot movement). 20 Guardrail panels; at least one rear guardrail panel (30) and preferably two side guardrails It consists of panels (40). These panels are made of a durable material such as galvanized steel. The panels are placed around the fixing feet (20) when not in use. They rotate and come to a horizontal position parallel to the cabin ceiling surface. In this way, the cabin is at its best. When it reaches the upper level, it can move without the risk of hitting the shaft ceiling. 25 If maintenance personnel climb onto the cabin roof, the guardrail system (10) can be easily installed. It is activated. Personnel shall, respectively, open the side guardrail panels (40) and the rear guardrail 4 He manually lifts panel (30) upwards. Each panel is closed at approximately 0°. It is moved from its original position to its open (vertical) position, which is 90°. When each rear guardrail panel (30) and side guardrail panel (40) are in the open position, The fixing lever (50) connected to that panel is engaged. The fixing lever (50) has one end one end near the railing panel, the other end near the fixing foot (20) or the cabin ceiling 5 It is a point-attached support element. When the panel reaches the vertical position, the fixing arm... (50) has a locking element (51) automatically or with a simple manual by locking the panel with movement, it involuntarily falls backward, i.e., to the closed position. obstacles. This structure ensures the stability of the railing in case of personnel leaning on it or in the event of an impact. This ensures that it stays in place. When the maintenance operation is finished, the personnel manually deactivate the interlocking element (51). By opening it, the railings are carefully brought back to the closed position. One of the most innovative features of the invention is the electronic control system. Each rear detecting the open and closed positions of the railing panel (30) and the side railing panel (40) There is an electronic control contact (60). These electronic control contacts (60) is connected to the elevator's main control panel. The system works as follows: 15 1. To put the elevator into maintenance mode, all handrail panels must be open and locked. It must be in the position "all open" from the electronic control contacts (60). The system enters maintenance mode until the signal is verified by the elevator control unit. It does not allow passage. 2. After the maintenance process is complete, the elevator will resume normal operation (passenger transport) 20 For it to return to its default mode, all railing panels must be in the closed position. Unless the "all closed" signal is received from the electronic control contacts (60) The elevator doesn't move. This electronic interlocking mechanism allows personnel to install or remove the railings. by completely eliminating human-caused errors such as forgetting to add up 25 It ensures maximum workplace safety. In one preferred application of the invention, the panels contact the cabinet ceiling. Non-slip and shock-absorbing vibration dampers (70) can be placed at these points. The wedges prevent the railings from vibrating and making noise when they are in the closed position. prevents. 30
