Detailed description of a preferential embodiment
With reference to Fig. 20 and 21, lifting up the anular knob (21) along the handle the plate (19) disengage the notches (6) allowing the rotation of the broom up to 180° around axis x, by gravity or by hand; releasing the anular knob (21) the plate (19) engage another couple of notches at a new degree.
With reference to Fig. 24, 25 and 26, the screws (13), following the centripetal and centrifugal movement of the buttons (11) provided by hand pressure and by the opposite pressure of the spring (12), slide keeping their vertical orientation in slots (10) which are fitted as to serve as a limit and a guide of the sliding; released the buttons (11) the heads of the screws (13) engages one couple of opposite grooves (15) in the housing on the broom-back (4), providing at the same time the fastening the base of the hinge (9) on the broom and its angular positioning; pushing the buttons (11) the broom can be unfastened or rotated, clockwise or anticlockwise, until a different angular position.
- a first spring locking and unlocking device inside the handle activated by means of a knob or similar along the handle allows a rotation of the broom up to 180° by gravity or by hand around the axis of the pivotal connection between the handle and the hinge, and allows the locking of the broom at multiple predefined angular positions;
- a second spring locking and unlocking device inside the hinge activated by means of two buttons on both lateral sides of the hinge allows a rotation of the broom up to 360° by hand around the central rotational axis of the connection between said base of the hinge and said housing on the broom, and allows the locking of the broom at different predefined angular positions;
- both said axes are orthogonal;
- said second spring locking and unlocking device inside the hinge also allows the fastening and unfastening of the broom with the possibility to change the implement having the same said housing;
- each angular position of the broom around each rotation axis can be combined with each angular position around the other orthogonal axis.
- a rectangular plate made of the appropriate material and thickness as to guarantee a strong locking engagement and substancially as wide as the internal diameter of the handle slides inside the handle in a constraining guide as to keep its main sides substancially on the same plane of said 180° rotation axis;
- said sliding of said plate is provided by the compression of an internal spring toward the hinge and by the lifting up of said knob along the handle its linked by an internal rod or wire or similar;
- said sliding make said plate to engage and disengage with its lower corners, coming out from the end of the handle on both sides of the ring termination of the handle, a couple of fitting notches placed at different degrees along the internal semicircular hedges of two supports of the hinge adjacent to said ring termination of the handle pivoting between them.
- said two buttons on both lateral sides of the hinge slides inside a rigid tube which serve as rotation axis of said pivotal connection between the handle and the hinge;
- a compression spring is inside said tube between said buttons as to keep both said buttons under a centrifugal pressure;
- said sliding of said buttons its centripetal under the manual compression oh the buttons;
- two screws or other element likewise shaped are fixed in the segment of both said buttons resting inside the tubular axis so that its upturned heads and a segment of its stems vertically come out from the base of the hinge through slots extended all along the thickness of said base of the hinge following the same said centripetal and centrifugal sliding of said buttons;
- said slots are fitted as to serve as a limit and a guide of said sliding of said screws;
- said housing on the broom has a circular cavity having on its internal circular edge a sequence of vertical grooves specifically fitted as to allow the engagement of said screws;
- said grooves are made in a sequence of specular couples disposed at different degrees around said 360° rotation axis, each couple corresponding to one angular position of the broom;
- said sliding of said screwe allows its engaging and disengaging said grooved of said housing on the broom providing at the same time the locking of the broom at one of the different angular position and the fastening and unfastening of said base of the hinge on the broom.
