<p>An adjustable platform to provide a level surface over stairs, comprising of a platform, height-adjustable legs, and extendable stabilizing lateral arms. The adjustable legs are attached perpendicularly to the bottom face of the platform. The height of the legs can be adjusted to create a level surface out of the platform, when the structure is mounted on a staircase. The platform's level can be checked with an integrated liquid level device. Stabilizing tension rods are integrated into the platform and extend outwards. By extending the rods to stabilize the platform using available surrounding vertical surfaces, lateral motion of the ladder can be minimized, preventing the platform from moving or slipping when force is applied along the platform. The extendable legs and tension rods allow the platform to be used in a wide range of staircases or stairwells with varying heights and widths.</p> |
