Abstract:
1. A roof rake system for safely and conveniently pulling shingles and nails from roofs comprising, in combination: a rigid handle in a generally cylindrical configuration having an upper end facing generally upwardly and a lower end facing generally downwardly during operation and use, the lower end being formed in a generally cone shaped configuration, the handle having a length being between 4 feet and 5 feet, with a central axis along its entire length, the handle being fabricated of a rigid material; a rigid head fabricated of a rigid material, with an interior region and an exterior region with an intermediate region there between, the interior region being hollow in a generally cone shaped configuration and securely receiving the lower end of the handle, the exterior region being cylindrically shaped over the majority of its extent as an extension of the intermediate region and with a free end formed with a taper facing the interior region; a flat plate in a rectangular configuration with a long leading edge adjacent to the free end of the exterior region and a long trailing edge adjacent to the intermediate region and short parallel side edges there between, the flat plate having a bottom face and a top face with a weld coupling the exterior region of the head to the top face of plate; a plurality of broad V-shaped projections at the leading edge of the plate forming laterally spaced crests with laterally spaced roots there between, a plurality of narrow V-shaped recesses at the trailing edge of the plate forming laterally spaced crests with laterally spaced roots there between, the intermediate region having a circular cross-sectional configuration and being curved with a radius of curvature of about 0.50 inches, and forming an angle of between about 40 degrees and 50 degrees, with the exterior region and plate being in a plane and located entirely beneath the lower end of the handle during operation and use, the crests of the broad V-shaped recesses adapted to receive a nail of a roof where after a user may pivot the system around the intermediate region of the head to remove the nail, the crests of the narrow V-shaped recesses adapted to receive a nail of a roof where after a user may pivot the system around the free end of the plate to remove the nail, the exterior region having a taper adapted to lift a shingle when a nail is about to be received by a broad V-shaped recess sliding in contact there with; a primary grip in an ergonomic curved shape removably received by the upper end of the handle and fabricated of a semi-rigid elastomeric material; and a secondary grip fabricated of a rigid material and having a loop portion positionable around an intermediate extent of the handle with semi-cylindrical sections having male threads, the secondary grip also having a grasping portion with internal female threads receiving the male threads, the secondary grip also having a tubular portion with an exterior face adapted to be pushed towards, and contacted by, the handle through the grasping portion and an interior face adapted to contact the grasping portion for securement purposes.
