Abstract
An adjustable ladder platform is an apparatus that aids in keeping extension ladders on firm, level footing having an open base frame that sits directly on the unlevel ground, roof surface, pavement or the like a flat surface, similar to a small tabletop that supports the feet of the extension ladder. The two components are then hinged together at one side of the frame. Then the opposite side is supported by two adjustable arms that are attached by bolts and wingnuts that can be attached and removed without tools. The arms are provided with multiple holes to accommodate varying grades. One side of the device is provided with an attached bubble level to ensure levelness of the upper platform to ensure safety. Finally, one side of the device is provided with a handle to facilitate transport.
Claims17
A platform leveling device, comprising:
- a platform base having a top surface supported by a pair of top side members;
- a bubble vial attached on a front face of one of the pair of top side members is adapted to assist a user when the top surface is level;
- a pair of support base members disposed on an interior of the pair of top side members to support the platform base;
- a cross member that is attached near a midpoint of the pair of support base members to provide structural stability;
- a pair of support arms each pivotally attached via a first fastener to each of the pair of support base members;
- and
- a main pivot fastener pivotally attaching the pair of top side members and the pair of support base members;
- and, wherein the platform leveling device is adapted to aid in keeping a ladder on a firm and level footing, when used on a non-level surface;
- wherein the cross member serves as a mounting point for a carrying handle, as well as a storage position for a pair of fastening systems as they cannot be stored in the pair of support base members due to proximity of the pair of top side members when the platform leveling device is in a closed state;
- and,
- wherein when in the closed state, a pair of forward stairway supports are folded, and a pair of rear stairway support blocks are stored on an underside of the platform base.
