Description

1 TARIFF FOLDABLE AND TRANSFORMABLE PORTABLE LADDER-PLATFORM SYSTEM Technical Area The invention relates to a foldable and convertible portable ladder-platform system. Specifically, the invention combines the functions of a type A ladder and a flat work platform in a single compact 5-inch device. It relates to a foldable and convertible portable ladder-platform system that integrates elements into the structure. State of the Art Various types of equipment are available on the market to meet the need for working at height. They are available. The most common type of this equipment is the A-type folding ladder. Staircases typically consist of three to five steps and offer only vertical access. 10 It is designed for this purpose. It requires the user to work while standing on the step. This structure, which does not offer a large and flat work surface, makes long-term maintenance and assembly difficult. or leads to serious ergonomic deficiencies in tasks such as painting. Narrow steps Its profile jeopardizes balance during two-handed operations and poses a risk to occupational safety. It falls short in terms of standards. Consequently, 15 people died as a result of falls from stairs. Domestic accidents constitute a statistically significant category of accidents. On the other hand, mobile scaffolding and work platforms that offer a flat working surface are also part of the technique. It should be evaluated within the context of the known situation. These systems offer the user a wide and fixed range of options. While providing a workspace, its structural characteristics result in high weight (typically (between 20 kg and 30 kg) and has a large volume. The equipment in question functions as a ladder. They are not visible, therefore users also need a ladder. This opens the door. Acquiring two separate pieces of equipment creates both an economic burden and... This creates practical difficulties in terms of storage and transportation, especially in cramped housing. The requirement to have separate storage volumes for two independent pieces of equipment in these areas, These are among the main factors that restrict the use of solutions. 25 Telescopic ladders offer a certain degree of flexibility in terms of height adjustment. While it offers these features, it lacks platform functionality and its unit cost is relatively high. This The products also do not provide a flat working surface, therefore the same basic technical problem exists. They are unable to solve the problem. A stool or chair is used as a temporary solution instead of stairs. 2 Alternatives such as these clearly offer an inadequate level of security and any It does not include standardization or load capacity guarantees. When the known solutions summarized above are considered together, the current state of the technique... the situation is far from offering a solution free from three fundamental technical problems It is understood that, firstly, both stair and flat work can be done with a single portable piece of equipment. 5 The problem is that the platform functionality cannot be met simultaneously; this situation forces users to work on two separate platforms. It forces the acquisition of the product. Secondly, it arises during work in a ladder position. The resulting lack of balance and safety, and ergonomic deficiencies. The third is the existing systems that require both portability and compact storage. The inability to accommodate; especially fitting two separate pieces of equipment into a standard vehicle trunk. 10 or transporting it by a single person presents difficulties. In conclusion, due to the negative aspects described above and the current solutions being the subject of discussion... Due to its shortcomings, an improvement is needed in the relevant technical field. It has been made.
