Stairway structure for building - comprises several cylindrical inflatable bodies of differing heights

摘要

The cylindrical inflatable bodies (1) have one or more hand grip components (3) and air valves. They are made from elastic and airtight material, forming a stairs due to their differing heights. They can be filled via the air valves either automatically or manually, using an air pump. The bodies are connected to one another via an air channel, and one or more non-stretch connecting straps connect the two base surfaces (10) of the cylinders axially from within. The hand grip components (3) are suspended on both sides of each cylindrical body, and a cap-shaped step plate with a retention edge is applied for protection to the ends of each body. USE - As an alternative to the use of ladders for building and similar operations.
