ABSTRACT:
An improved frame for a floor wiper consisting of two frame members (1,2) designed to fold towards on another about a pivot pin (3) and to be locked in their fully extended or open position by means of a locking mechanism (4,5) is simplified in its construction and can be made with a minimum of material and component parts providing one frame member (1) has a T-shape and the other frame members (2) a U-shape which makes with the T a substantially rectangular plate and providing the pivot pin (3) extends substantially perpendicularly of the longitudinal axis of the T and U arms (10,15) and providing the locking mechanism contains a permanent-magnet clamp (4,5). To reduce the volume and weight of the permanent magnet (4), the force arm (K) on which the magnetic force acts is intended to be as long as possible.
