DESCRIPTION:
BRIEF SUMMARY
The invention relates to a plastic gutter.
It is known to assemble plastic gutters by glueing in that an assembly piece is for example placed with its inside in close engagement with the outside of the end zones of the lengths of gutter and in that a layer of glue is applied between these surfaces. The glue partly serves to provide complete tightness and partly to connect the two lengths of gutter so that they cannot move in relation to each other or in relation to the assembly piece. End caps, spout joints, connectors, corner joints and similar assembly pieces are fastened in the same manner.
It is widely felt to be a drawback that the parts have to be glued together and it also requires a certain degree of care to make a correct assembly by glueing. Leaking glue may give an undesired discoloration, and in damp weather it may be very difficult to carry out the assembly work by glueing. The used types of glue moreover contain poisonous solvents and are unpleasant to work with.
There is therefore a great demand for plastic gutters which can be assembled without any use of glue, and various structures have also been suggested, such structures having packing rings of rubber or similar material that are placed in grooves or similar recesses in the assembly pieces and the lengths of gutter. Such packing means, however, will not provide sufficient hold against axial displacement so that such displacement will either have to be tolerated or neutralised by means of special assembly means or fastening means.
Danish patent specification No. 133,707 describes a plastic gutter where the individual parts are assembled and held together by detachable pushbutton pins made of a flexible plastic material and where the waterproofing is obtained by applying a suitable jointing filler between the cooperating surfaces. This structure, however, is also encumbered with drawbacks in that the lengths of gutter will have to be provided with holes for the pins at the place of assembly and in that it must be ensured that the jointing filler fully encircles the pin holes so that the gutter is waterproof. This structure also has the drawback that just like glued gutters it is difficult to repair and take down because the jointing filler will bind the parts so strongly that they are often damaged when an attempt is made to take apart the gutter at their places of assembly.
The object of the invention is to provide a new structure of a gutter with assemply parts which requires neither glue nor jointing filler but where it is possible to use an ordinary rubber packing and still be quite sure that no axial displacement will occur between the parts and where a gutter structure is obtained which is quickly and easily mounted and taken down.
Such a structure can always be disassembled in that there are no permanent assemblies, the assembly being still so strong that the parts will not displace axially in relation to each other. As a packing it is possible to use a rubber packing but various jointing fillers can of course also be used if so desired. The assembly will always by quite tight because there are no holes neither in the lengths of gutter nor in the assembly parts. Such a gutter may be assembled and mounted in all kinds of weather and without any problems since the individual parts are simply snapped together so that the locking pieces engage the locking holes.
According to another aspect of the invention, lengths of gutter that can still be manufactured by extrusion as the known gutters but where the locking pieces are formed by a simple finishing. If only part of the longitudinally extending bead or beads are machined to form locking pieces, the unmachined part of the bead or beads will act as a reinforcement of the length of gutter so that it is possible to form same with a smaller wall thickness than normally or it is possible to obtain a gutter which is much more solid than the known gutters.
In another aspect of the invention the locking pieces will be placed at the most advantageous places of the gutter and a strong reinforceme
