Description

1 TARIFF INNOVATION IN STAIRCASE DESIGN TECHNICAL AREA 5 The invention relates specifically to stair systems used for transportation and access purposes; further Specifically, by joining the body and step components using laser welding technology. The invention relates to the production of a high-strength, lightweight, and aesthetically pleasing stair structure. The invention is primarily used in construction, 10 across a wide range of sectors including industry, domestic use and storage areas It focuses on developing usable, safe, and easy-to-manufacture ladders. STATE OF THE ART The currently used ladder models commonly used in the industry are generally constructed using riveting, 15 body and step structures joined by bolting or spot welding methods This is how it is formed. In stairs manufactured using these traditional methods, the connections deteriorate over time. Structural weaknesses such as loosening, deformation, and cracks can occur at these points. In addition, the fasteners and thick metal reinforcements used increase the product weight, This also leads to negative consequences in terms of portability and user ergonomics. 20 These structures are also aesthetically flawed, with visible welding marks and screw heads on the outside. or due to rivet points, it presents an aesthetically poor appearance. Production Since the processes are generally based on manual operations, they have high labor requirements and low costs. This brings with it problems such as standardization and the risk of errors. 25 These production methods, especially those that cannot be integrated into automation systems, result in high production output. This results in increased costs and low efficiency, which is uneconomical for producers. This makes sustainability difficult. Current stair solutions lack structural integrity and aesthetics. It falls short in terms of integrity, weight, ease of production, and compatibility with automation. 30 In the known state of the art, the invention is "Portable ladder" with application number TR 2023 / 017314.

It is useful, axially connected to a central plate, and during use as mentioned Two symmetrical legs consisting of a central plate and side plates that form a "U" shape. and the units consisting of a step connecting the aforementioned symmetrical legs to each other 10 It is a ladder formed by joining the desired number of pieces end-to-end; it is easy to assemble. In order to enable this, between the ear plate (11) and the middle plate (12) and / or in the middle having at least one winding spring (40) positioned between plate (12) and outer plate (13) It is characterized by having a foot (10) which is summarized as " Another known instance of the art is the “Portable ladder” with application number TR 2019 / 07876. The utility model application titled "Invention" states that "The invention can be used in all open and closed areas such as homes and workplaces." It refers to a sturdy and practical portable ladder developed for use. The mentioned Portable ladder with iron steps added to the bottom of the plastic-based material. Made of sheet metal, the step support plate strengthens it and makes it usable. 20 It has been brought in. In the aforementioned portable ladder, the steps are made smaller from bottom to top. Thanks to its design, a strong downward force has been achieved. The aforementioned portable ladder... The system is reinforced with sheet metal and a locking mechanism added to the holding points, ensuring durability. Its lifespan has been extended thanks to the reinforced structure of the aforementioned portable ladder. This is summarized as "weight-bearing capacity has been increased." 25 In conclusion, the existence of the above problems and the inadequacy of the current solutions are related to the technical aspects. This has made it necessary to make improvements in this field. THE PURPOSE OF THE INVENTION 30 The present invention meets the aforementioned requirements while eliminating all disadvantages. It relates to stair treads, which lift and offer some additional advantages. With this invention, the stair shaft and step components can be formed by laser welding 35 By combining them, the connection weaknesses and aesthetic flaws encountered in existing systems are eliminated. 3 eliminating problems such as high weight and low production efficiency that is intended. Mechanical connections between the stair shaft and the steps, such as drilling, riveting, or screwing. by directly joining them with a laser source without the need for additional methods; 5 Making the connection points high-strength increases the load-bearing capacity of the product. The aim is to increase durability and achieve a long-lasting structure. In addition, eliminating fasteners makes the product lighter and more compact.

The side view of the stair step (1) in question is shown. Step (1) and body (2) Laser welding is used during the joining of the profile. In this way, the steps (1) both ends are positioned to contact the vertical body profiles (2) 15 and these contact surfaces - source points (1.1) - are connected using a high-energy laser beam The merging process is being performed. Laser welding is typically performed using a fiber laser or solid-state laser welding machine. The laser beam, when focused on metal surfaces, short-circuits the material at the points of contact. It melts in time. The melting areas are the metal structures of the step (1) and body (2) profile. They are joined together to form a single piece, thus eliminating the need for any additional welding wire, rivets, There is no need to use screws or bolts. During the welding process: 25 • Steps (1) are placed and fixed in line with the body (2). • The laser beam is applied to the joining surface in a controlled and focused manner. • The molten material cools rapidly, forming a high-strength weld point. This ensures both structural integrity and prevents any issues at the connection points. No protrusions, screw heads, or weld strips are visible. Heat input of the laser welding process. Because the risk is low, the risk of warping and deformation of the material is minimized. It is being downloaded. This sourcing process also provides a clean appearance from an aesthetic point of view. and by increasing the connection strength, a long-lasting and robust stair structure is created. 35 is being created.
