Abstract
Abstract The present invention relates to a downpipe (10) provided with a longitudinally extending slot (16). When joining two downpipe sections together, by means of a longitudinal join or an angled join, the longitudinal slot enables the upper downpipe section to be compressed slightly so that it can be readily pushed into the lower downpipe section. Pipe-bends intended, for example, to serve as water outlets, may readily be formed by cutting a notch or recess (22', 22") through the flanges (14) defining the slot (16) and through the laterally located legs (18) of the downpipe, and then forming a fold at the bottom of the notch in the rear side (20) of the downpipe. Pipe-bends and water outlets can be fixed in position by joining together the overlapping sides with the aid of screws, rivets or like fasteners (26). The longitudinal slot of two adjacent sections can face in opposite directions.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
89 words
A downpipe, connectable to guttering on the outsides of building structures, comprising: at least an upper tubular section and a lower tubular section, each section having a front side including an open longitudinally extending slot and a solid rear side disposed opposite said front side; and a longitudinal joint between said upper and lower sections produced by slightly compressing the upper section and inserting it in the lower section, the front side of said upper section being disposed adjacent the rear side of the lower section at said joint.
Claim 2
Dependent Claim
89 words
A downpipe, connectable to guttering on the outsides of building structures, comprising: at least an upper tubular section and a lower tubular section, each section having a front side including an open longitudinally extending slot and a solid rear side disposed opposite said front side; and a longitudinal joint between said upper and lower sections produced by slightly compressing the upper section and inserting it in the lower section, the front side of said upper section being disposed adjacent the rear side of the lower section at said joint.
Claim 3
Dependent Claim
25 words
A downpipe according to claim 1, characterized in that the downpipe presents an inwardly directed, longitudinally extending fold on a side thereof opposite the slot.
Claim 4
Dependent Claim
22 words
A downpipe according to claim 1, characterized in that edges of the slot define inwardly directed, angled flange parts or double folds.
Claim 5
Dependent Claim
66 words
A downpipe according to claim 1, having a substantially rectangular cross-section, wherein the downpipe comprises a pipe-bend formed in said upper section by a notch extending through flanges defining the slot and through laterally located legs up to a side opposite the slot, and a fold at said rear side so that legs on the lower section are located outside corresponding legs on the upper section.
Claim 6
Dependent Claim
30 words
A downpipe according to claim 1, in which two down-pipe sections are joined together by means of screws, rivets or like fasteners, placed in laterally located legs of said section.
Claim 7
Dependent Claim
37 words
A downpipe according to claim 1, wherein the downpipe is secured to a wall of a building or like structure with screws, nails or like fasteners, passing through a rear wall of the downpipe opposite the slot.
Claim 8
Dependent Claim
34 words
A downpipe according to claim 6, and further including spacer means and the screws, nails or like fasteners being directed obliquely upwards through openings made by said fasteners through the wall of the downpipe.
Claim 9
Dependent Claim
39 words
A downpipe according to claim 1, wherein two of said downpipe sections are joined together by means of screws, rivets or like fasteners placed in tongues carried by, and projecting outwardly from at least one of, said downpipe sections.
Claim 10
Dependent Claim
39 words
A downpipe according to claim 6, and further including spacer means, the screws, nails or like fasteners being directed obliquely upwards and provided with seals in through openings made by said fasteners extending through the wall of the downpipe.
Claim 11
Dependent Claim
82 words
A downpipe connectable to, and extending downwardly from, guttering on the outsides of building structures, comprising: a first tubular section and a second tubular section, each of said first and second tubular sections including a front side having an open longitudinally-extending slot and a solid rear side disposed opposite said front side, and a joint between said first and second tubular sections, the front side of said first section being contiguous with the rear side of said second section at said joint.
Claim 12
Dependent Claim
82 words
A downpipe connectable to, and extending downwardly from, guttering on the outsides of building structures, comprising: a first tubular section and a second tubular section, each of said first and second tubular sections including a front side having an open longitudinally-extending slot and a solid rear side disposed opposite said front side, and a joint between said first and second tubular sections, the front side of said first section being contiguous with the rear side of said second section at said joint.
Claim 13
Dependent Claim
24 words
The downpipe of claim 10, wherein said joint comprises an end of said first section interfitted within an adjacent end of said second section.
Claim 14
Dependent Claim
132 words
A substantially vertically extending downpipe connectable to guttering on the outsides of building structures, comprising: a channel member comprising a front side having an open longitudinally-extending slot, a solid rear side disposed opposite said front side, and side legs interconnecting said front and rear sides, notched means, disposed at a location along the length of said channel member, for dividing said channel member into said first and second tubular portions, and the side legs of one of said first and second tubular portions adjacent said dividing means being compressed and inserted into the space defined between the side legs of the other of said first and second tubular portions, whereby within the longitudinal extent of the downpipe one of said sections is disposed at an angle to the other of said sections.
Claim 15
Dependent Claim
132 words
A substantially vertically extending downpipe connectable to guttering on the outsides of building structures, comprising: a channel member comprising a front side having an open longitudinally-extending slot, a solid rear side disposed opposite said front side, and side legs interconnecting said front and rear sides, notched means, disposed at a location along the length of said channel member, for dividing said channel member into said first and second tubular portions, and the side legs of one of said first and second tubular portions adjacent said dividing means being compressed and inserted into the space defined between the side legs of the other of said first and second tubular portions, whereby within the longitudinal extent of the downpipe one of said sections is disposed at an angle to the other of said sections.
