<p>The invention relaters to building engineering, in particular to roof rain gutter structures, and can be used for as a device for removing garbage form the rain gutters. The inventive hinged unit comprises reciprocating vertical rods (2) forming jointly with straps (3) a four-link joint which is fixable to a building wall at the points of the axes of rotation (4) thereof, embodied in the centres of the straps (3). Handles (5) are put on the joint axes at the ends of the rods (2). Collapsible stops (6) for fixing the unit in a position (A), when the gutter structure is coupled, is arranged under the lower strap near the handle (5). The gutter movable link (1) connectable to the upper rod ends is embodied in the form of the segment of a stepped sleeve in such a way that, when the unit is in the position (A), the end surface of the gutter approaching section (7) is tightly clamped on one end the gutter discharging section (8) is complementary butt-fitted on the other end. Said invention increases the cleaning efficiency for removing foreign matters from the rain gutters and makes it possible to carry out routine maintenance without professionals.</p> |
