发明名称 Magnetic rake
摘要 A magnetic raking device for cleaning up of dangerous ferro-metallic particles in and around construction jobsites, parks and playgrounds. A device able to perform the duties of both a conventional rake and a magnetic pick up device in one simple step. A hand operated magnetic raking device comprises a housing with a magnet or magnets placed inside. Teeth extending away from the housing are shaped in a fashion as to provide maximum agitation in surfaces such as grass, gravel and hard packed dirt. Device can be used inverted with the teeth facing up along smooth surfaces to pick up ferro-metallic particles without agitation. A handle is mounted to the housing to provide for easy push/pull use of the device. Length of head and handle may vary according to size and scope of area to be raked and cleaned of ferro-metallic particles such as nails and screws.
