Abstract
The tool has a folded position and an unfolded position. It will generally include a head assembly and an articulated handle. The handle can also be used alone. The handle, or the tool with such handle, occupies only a very compact space once in a fully folded position. It may thus be easily carried and stored when not in use. It can be folded and unfolded with only a minimal manipulative effort and level of difficulty. The main constituent parts cannot become detached and this unitary design alleviates the risks of parts being misplaced or lost.

A tool configured as a snow removal device, including:
- a head assembly including a brush, said the brush including a plurality of bristles that are attached to a main body;
- an articulated handle having a stretched configuration and a collapsed configuration, the handle including:
- a proximal elongated hollow outer segment, the proximal outer segment having a proximal end and at least one longitudinally extending slideway;
- a distal elongated hollow outer segment, the distal outer segment having a distal end;
- an intervening hinge joint pivotally interconnecting the outer segments in juxtaposition, the outer segments being in alignment along a longitudinal axis when the handle is in the stretched configuration, and being folded back on one another when the handle is in the collapsed configuration;
- and
- a proximal and a distal elongated inner segment slidably mounted inside the outer segments, the inner segments having complementary end members that are self-interlocking in a linear force-transmitting engagement when the handle is in the stretched configuration, the inner segments being detached from one another when the handle is in the collapsed configuration;
- and
- a linkage assembly operatively attaching the handle to the head assembly, the linkage assembly including a sleeve member in sliding engagement with the proximal outer segment, the proximal outer segment being axially movable, with reference to the sleeve member, between at least a retracted position and an extended position, the proximal end of the proximal outer segment being further away from the sleeve member in the retracted position than in the extended position, whereby, when the proximal outer segment is in the extended position while the handle is in the stretched configuration, the interlocked complementary end members attaching the inner segments being positioned out of alignment with each junction between the outer segments.
