Abstract: A dual function locking bracket for holding and supporting the handle of a push broom or other hand cleaning push tool. The bracket is configured to support the handle in two different positions. For use in transporting and merchandising circumstances, the bracket holds and secures the handle close to the brush or cleaning head of the broom, with the longitudinal axis of the handle parallel to the length dimension or longitudinal axis of the cleaning head. The bracket can be readily removed and converted to retain the handle in a cleaning use mode. Use of the bracket in this manner forms an immovable connection which prevents the handle from coming loose from the cleaning head joint with the handle, supplies an extra measure of stability to the broom at its handle/cleaning head joint, and provides the handle additional strength to prevent handle breakage.

Abstract: An article such as a broom back coated with a covering comprising a layer (9) of thermoformable plastic material. The broom backs (1) are introduced in a chamber (6) of a thermoforming machine (5) radiating panel (8). A plate of thermoformable material is put on the broom backs (1) and by the action of the heat radiated by the panel (8) and under vacuum condition the plate melts forming a layer (9) which wraps the broom backs (1) almost completely. The coating layer (9) thus formed after deformation maintains its colour and brightness and inscriptions and fancy drawings can also be preprinted on it. The covering formed by said layer (9) comprises an upper and a side surface completely wrapping the upper and the side faces of broom backs (1) and a lower bent edge partially coating the lower face (2a) thereof. The layer (9), which preferably is of PVC or polystyrene, advantageously preprinted, is firmly secured to the broom backs (1) after cooling.

Abstract: A versatile broom, brush or similar floor care implement comprises a head anchoring on a first side thereof a multiplicity of bristles presenting a substantially-flat bristle surface, and an integrally-formed connector-mating structure on an opposed second side of the head. The cleaning implement is maneuvered by an elongated handle disposed at a variety of preselected angles. Intermediate the head and handle is a handle interconnector to which the handle is detachably secured at one extremity and a connection assembly is ratchetably-pivotably secured at the other extremity. The connection assembly and the integrally-formed connector-mating structure on the head interact so that the handle can be selectively pivoted in a single plane as much as 180.degree. or more and locked at any of a number of preselected angles relative to the substantially-flat bristle-end surface.

Abstract: A broom specially designed for cleaning debris out of holes and cracks in asphalt and concrete prior to patching has a round broom head. The round head allows the broom to penetrate narrow holes and cracks resulting in more efficient and effective cleaning. The bristles are made of polypropylene and are similar to bristles used on street cleaners. A bristle band is free to move along the bundle of bristles, variably compacting the bristles for particular applications.

Abstract: A brace for a tool having an elongated handle and a working head disposed perpendicularly to the handle, such as a push broom, has a slidable collar and a pair of buttress rods. The working head is provided with a pair of holes on a top side, each hole being spaced from a center of the tool head on opposite ends of the tool head with respect to the center. The buttress rods are thick wires, each have a downward facing prong inclined for insertion into each respective hole for engaging in tension and compression. Each buttress rod generally defines a leg portion angled upwards from the prong and tool head towards the handle. An upper end of each buttress likewise has a prong or arm angled so as to lay flat adjacent the broom handle, parallel to a longitudinal axis of the handle and also engaging in tension and compression. The upper prongs fit into oppositely disposed channels of a collar fixed axially on the handle.

Abstract: A paint brush storage bag assembly for storing a paint brush in a storage liquid between uses and holding the brush while in use. The assembly comprises a foil bag for receiving the bristles and the adjacent portion of the ferrule therein.
