发明名称 Magnetic-vacuum-cleaner attachment for picking up metal objects
摘要 The present invention is directed to a magnetic pick-up attachment for conventional vacuum cleaners, the attachment being designed to be mounted under the housing of the cleaner and rearwardly of the vacuum intake to prevent the vacuum cleaner from being restricted in its movement. The attachment includes a magnet interposed between two oppositely disposed, protective, cover members which are secured to a bracket having an arm member and an end clamp. The attachment is secured to the side wall of the vacuum-cleaner housing by the end clamp, so as to project inwardly thereof. The arm further includes a longitudinal slot which allows lateral adjustment and placement of the magnet along the arm.
