Abstract

A gutter system comprising a number of gutter sections (1) with a convex outer surface (5) and gutter fittings (6) with a concave inner surface (7) adapted for receiving and fixing the open end of two gutter sections so that the convex outer surface (5) of each gutter section (1) rest against the concave inner surface (7) of the gutter fitting, and where the gutter fitting (6) comprises one or more indentations (8) arranged in the concave inner surface (7) and the gutter section (1) comprises one or more projections (10) arranged on the convex outer surface (5) of the gutter trough (2), and where the one or more indentations (10) and the one or more projections (8) are adapted so that the one or more projections (10) can be inserted into the one or more indentations (8) with a snap fit.

Abstract

A gutter system comprising a number of gutter sections and gutter fittings, and where a gutter section comprises a gutter trough extending along a longitudinal axis with at least one open end with a convex outer surface and where a gutter fitting have a concave inner surface and is adapted for receiving and fixing the open end of two gutter sections so that the convex outer surface of each gutter section rest against the concave inner surface of the gutter fitting, and where the gutter fitting comprises two grooves having an undercut cross section and being open at one end and where the gutter section comprises one or more projections arranged on the convex outer surface of the gutter trough, each projection having corresponding cross section al- lowing that the projection can be inserted into and slide in a groove from its open end.

Abstract

A coupling for interconnecting two items (3, 15), the coupling comprising a female part attached to one of the two items 3, and a male part attached to the other of the two items (15). The female part comprises a projection (11) extending only on one side of a plane parallel to the first axis of rotation (6) and away from the end of the circular cylindrical hole (5) and forming a segment of a circular cylindrical inner surface (13), and the tap of the male part further comprises a circular cylindrical proximal end (14) extending between the distal end (8) and the other of the two items (15). A groove (16) is arranged in one, and a corresponding flange (17) is arranged on the other one of the circular cylindrical inner surface (13) and the circular cylindrical proximal end (14), and the flange (17) and the groove (16) are adapted such that the flange (17) can slide in the groove 16 about the first axis of rotation (6), when the tap is rotated in the circular cylindrical hole (5). The distal end of the tap, in the direction along the second axis of rotation, is longer on one side of the second axis (10) of rotation than on the opposite side.
