PCT No. PCT/DK85/00003 Sec. 371 Date Sep. 5, 1985 Sec. 102(e) Date Sep. 5, 1985 PCT Filed Jan. 23, 1985 PCT Pub. No. WO85/03541 PCT Pub. Date Aug. 15, 1985.A plastic gutter is designed with a longitudinally extending bead (5) under an outwardly facing lip (4) and a corresponding longitudinally extending bead (5) on the inside of the rear part. At least at the end of each length of gutter the longitudinally extending beads have been machined in such a manner that material has been removed at regular intervals so that the remaining material constitutes one or more locking pieces (6). An assembly piece (7) with a rubber packing (8) for assembling adjoining lengths of gutter, for example, has a number of locking holes (9) in an outwardly facing lip (11) and a number of corresponding locking holes (9) in a bent edge part (10) at the rear. There is hereby obtained a gutter which is both quickly and easily mounted and taken down and where the parts are nevertheless securely held together so that an axial movement between the parts will not occur. |
