Abstract:
In an angularly adjustable universal bracket adapted for connection to a concrete leveling/finishing tool having a bottom generally defining a plane with the finishing tool having a centrally disposed rectangular reinforcing and handle mounting bar, the combination comprising:a base plate having a top and bottom surface with a plurality of spaced holes extending between the surfaces through which bolts may be inserted for attaching the base plate to a leveling/finishing tool, the base plate defining an elongated lateral mounting slot extending upwardly from the bottom surface for receiving a finishing tool's rectangular reinforcing and handle mounting bar;a yoke pivotally mounted to the base plate, the yoke defining a cylindrical passageway therein aligned along a longitudinal axis disposed generally at a right angle to the mounting slot and the axis about which the yoke pivots, the yoke further defining an upper arcuate portion and a guide slot therein circumscribing a semicircular arc of about 180.degree., the guide slot having side and end walls with the end walls being aligned generally along a lateral axis generally parallel to the base plate and perpendicular to the longitudinal axis;a tubular handle receiving member having an outer wall and extending through the cylindrical passageway in the yoke and adapted to rotate therein, the handle receiving member having a distal end located beyond the forward end of the yoke;a caming ring secured to the distal end of the handle receiving member for rotation therewith, the caming ring defining a pivot point spaced from the longitudinal axis;an actuating rod pivotally mounted between the caming ring pivot point and the base plate so that the base plate and a leveling/finishing tool secured thereto will pivot around the pivot axis when the handle receiving member is rotated; anda stop member secured to the handle receiving member and having a free end which rides in the yoke guide slot for limiting the degree of rotation of the handle receiving member and for transferring longitudinal forces applied to the handle receiving member to the yoke and base plate, the caming ring pivot point moving from about a 3 o'clock position to a 9 o'clock position as the stop member moves from one end wall of the guide slot to the other end wall.
