摘要： A ladder support device removably securable to the hitch receiver of a vehicle. The ladder support device comprises a frame having adjustable ground engaging legs. The frame includes a pivoting arm to be removably secured to the hitch of a vehicle to allow the frame to be positioned in a desired orientation relative to the vehicle. The frame includes a pair of brackets for receiving the feet of an extension ladder therein. Further, the frame comprises a pair of telescopic support arms that extend upward from the frame and that can be secured to a portion of the extension ladder so as to secure the ladder in an upright, angled orientation without having to rest the ladder against a support surface, such as the side of a building.

摘要： Embodiments of the innovation relate to a support apparatus for use with an elongate structure, such as a chimney. In one arrangement, the support apparatus includes a base configured to extend along both sides of a pitched roof surface, a set of vertical supports secured to the base and configured to be secured to the chimney, and a set of platforms connected to the set of vertical supports and configured to at least partially extend about the perimeter of the chimney. Each platform of the set of platforms is connected to a corresponding adjacent platform of the set of platforms.

摘要： A portable leveling device capable of supporting any types of ladders, scaffolds, and other objects requiring leveled support regardless of object size when a plurality of the devices is used. The device may be deployed by one hand automatically and instantly quick over a terrain of virtually any profile. The device is capable of projecting an extension ladder position eliminating human error and reducing deployment time when the ladder is actually positioned. The device is capable of indicating deployment faults before use and allows visual inspection of the parts at fault without disassembling. The device is lightweight, can be easily carried with one hand, and stored compactly.

摘要： In one embodiment of the present invention, SHINGLE KNIFE™, comprises a pneumatically powered miniaturized reciprocating or circular saw designed especially for roofing applications. In an alternative embodiment, SHINGLE KNIFE™ may be powered by rechargeable battery packs or the like. SHINGLE KNIFE™ is roughly size and shape of a Prior Art razor knife, but may be powered and provided with a depth gauge to prevent cutting through roofing underlayment or the like. In another embodiment of the present invention, the SHINGLE KNIFE™ may be provided for cutting sheetrock. A reciprocating, sharpened hook shaped blade pulls though the sheetrock, making a clean cut with little or no powdery debris. The SHINGLE KNIFE for sheetrock may be air or battery powered.

摘要： A ladder leveling device that is free-standing and is not installed, or fixed to, the existing ladder (80). Simple, one-person operation of device provides quick convenient way to establish a level and stable work surface over non-level ground, allowing the safe mounting of most common ladders onto device frame (10). Trough (12) provides safe and secure positioning of ladder on top of leveled device. Range of device support, leg (25), adjustment is adequate to provide for safe use on common residential stairs. Infinite adjustment of supports allows precise leveling. Inclinometer (40) displays precise, accurate device-leveling information for safety and ease of operation. All-terrain footing devices (30) provide sturdy use on various ground types.

摘要： Improvements to the leg extension of an adjustable ladder leveler and, more generally, improvements to ladder legs. A shoe with fastener holes to reduce leg slippage. A shoe with a claw that folds to be parallel to the ladder leg and then slides upward with respect to the leg thereby becoming locked into position so that it cannot move away from being parallel so long as weight is applied on the ladder. Increased length and modified shape on the distal ends of control levers on the extendable leg ladder leveler so that the levers can be operated with a foot and do not require hand operation.
