Description

1 / 7 DISPOSITION INTRODUCED IN LIFELINE SUPPORT WITH ENERGY ABSORBER

[001] This utility model relates to a new model of Lifeline Support with Energy Absorber, which is a device composed of an interface support with an attached energy absorber, to be used with steel cables, clamps, thimbles and a certified anchor eye. The support will be used in a fall arrest system, with a self-drilling screw type fastening element to be fixed on roofs and coverings of all types. For safe access, the duly trained employee must be carrying a compatible connecting element such as a lanyard with energy absorber or retractable fall arrestor and a full-body harness. FIELD OF APPLICATION

[002] The Lifeline Support with Energy Absorber, object of the present utility model, is applied to roofing systems with metal tiles with channels and channel cap, to be used with steel cables, clamps, thimbles and anchor eye certified as a safety element to perform work at height and at the same time protect the roof structure. PURPOSE OF THE UTILITY MODEL

[003] The Lifeline Support with Energy Absorber, the subject of this utility model, aims to provide greater safety when performing work at height while protecting the roof structure. PROBLEM TO BE SOLVED

[004] In order to provide greater safety when performing work at height and at the same time protect the roof structure, facilitate installation Petition 870250004936, dated 01 / 22 / 2025, page 7 / 17 For a 2 / 7 metal roof covering, the Lifeline Support with Energy Absorber, the subject of this utility model, was developed. This new support features an innovative energy absorption system. In addition to the energy absorption system, this new support has a unique design that improves the usability of the "C" type anchoring device (horizontal lifeline). With its horizontally positioned cylindrical body and an approximate maximum height of 200 mm, our support does not transmit the high loads that could be generated by the "lever" movement when arresting a worker's fall. STATE OF THE ART

[005] There are some patent documents that describe anchored roofing systems and safety systems for residences with metal roofing, but none of these documents discloses a Lifeline Support with Energy Absorber, such as its configuration and operation as described herein. Among these documents, the following can be highlighted:

[014] The Lifeline Support with Energy Absorber (1) comprises: a reinforced metal base (2) for direct fixing to the trapezoidal roof tile or fixed to an interface support for zipped roof tiles; a metal cylinder body (3) with an internal energy absorption system, composed of a central steel rod (4) with threaded ends (5), supported by a bushing (9) and washer (10), containing inside a steel spring and PU round bar (6), and a mounting fixing cover (11); also comprising a certified anchor eye (7) for steel cables fixed to one end of the cylinder and another certified anchor eye (8) for steel cables fixed to one end of the steel rod (4); where the elements working together absorb energy in case of a fall, mitigating the shock that the person could receive in that case, preventing damage to the person's body structure. OPERATION AND USE OF THE UTILITY MODEL

[015] The Lifeline Support with Energy Absorber (1), if applied to Roofs (coverings) with Zip-Lock Tiles, where drilling is prohibited, the devices are fixed using adapted supports for Petition 870250004936, dated 01 / 22 / 2025, page 11 / 17 6 / 7 embrace the crests of the tile waves and are secured by screws, making the system completely secure against pull-out. The supports will always be fixed in the locations where the tile fixing clips are found, to ensure greater strength.

[016] The Lifeline Support with Energy Absorber (1), if applied to other types of roofs, (Roofs), with various other types of tiles, where the tiles are already perforated, the device will have its bases installed on the crests of the tile waves, fixed with through or self-drilling screws, always seeking to reach the beams of the metal structure, where it will find greater resistance.

[017] The Lifeline Support with Energy Absorber (1), when applied to concrete beams or columns, the device will have its bases fixed with anchor and screw systems. In all cases, steel cables will be used, fixed to the eyelets located at the end of the cylinder, using clamps and thimbles as indicated in the current standards.

[018] The Lifeline Support with Energy Absorber was developed for each type of project, being suitable for all types of roofing, providing complete safety in the execution of work at height suitable for all roofing systems; with an individual load capacity of 1,500 kg per support; meeting ABNT standard 14626, and is even approved by the Technological Research Institute - IPT; and with a low cost compared to the market.

[019] Thus, the Lifeline Support with Energy Absorber, the subject of this utility model, as described above, presents a new and unique configuration that gives it the great advantage of being highly efficient and safe, developed according to current standards and Petition 870250004936, dated 01 / 22 / 2025, page 12 / 17 7 / 7 properly tested, ensuring the safety of people who need anchorage for work at height and reduces the impact on the metal structure (if applied to trapezoidal roofing sheets) and on the roof (if applied to zip-lock roofing sheets).

[020] Thus, due to the configuration, application and operation characteristics described above, it can be clearly seen that the DISPOSITION INTRODUCED IN LIFELINE SUPPORT WITH ENERGY ABSORBER is a new element for the State of the Art which has unprecedented conditions of innovation, inventive act and industrialization, which make it deserving of the Utility Model Patent Privilege.
