Definitions

• the present invention refers to a gutter of the type, which is more closely stated in the preamble of the patent claim 1.
• the invention refers further to the use of the gutter to support and firmly hold a roofing to form an overhung roof structure.
• the gutters is a usual specific problem in houses. They are frequently of a too pliable construction and may be deformed or get broken and then do not perform their purpose. Further damages and other problems may arise in the connection to the eaves, so that moisture enters and decay occurs in the hanging-over. To prevent this, the roof panel at the bottom is generally covered by a protection plate. However, this is frequently too short and besides water may penetrate into the nail holes.
• roofs may be provided with special snow slide protec ⁇ tion. These make the roof structure appreciably more expensive and at the same time is a delicate item of the construction, where leaks may occur with penetration of water and decay dama ⁇ ges.
• the object of the invention is therefore to provide a gutter, that solves above said problem with roof mounting and which also eliminates the drawbacks of older gutter designs, has a robust construction which wholly protects the eaves from water flowing downwards the roof and contribution of precipi- tation, which at least partly prevents collection of leaves in the gutter as well as acts as a snow slide protection, but which primarily enables to mount a roof without having to perforate the same with nails and screws.
• the gutter is designed as stated in the charac- terizing part of the patent claim 1.
• the gutter exhibits internally of the gutter arranged gutter hooks.
• the gutter hooks very rough dimensions without disturbing the appearance of the building or form projecting parts, which might constitute risks of hazard.
• the gutter also becomes enough stable to support the lower part of the roofing, for example a roof plate.
• An additional object of the invention is to achieve a use of a device according to the invention to function as a mounting aid for roofing for an intended building.
• Said additional object is achieved by means of a use according to the invention, which in the main is characterized therein, to fixedly hold at least the lower end of a roofing by surrounding apply it about the lower end of the roofing so that the roofing from above is held down against an underlay by an upper shank, whereby the device at the same time forms a gutter part for rain-water extending along the lower edge of the roofing.
• the present invention eliminates all above-mentioned risks, since the roofing sheet-metal is mounted completely without perforating through leads - one of the variants is even completely unscrewed in order to increase the life-span and ensure the seal layer.
• the roofing sheet-metal at the lower edge is clamped in the eaves element where the ridges of the roofing sheet- metal lie against an L-iron.
• the roof water can pass down in a profile groove of sheet-metal for further run-off to drain locations.
• This profile groove at the same time constitutes an eaves lining which hides the cross cut profile edge of the roofing sheet-metal.
• the device also gives possibility of simple leaf cleaning and at the same time is an efficient snow slide protection.
• the roofing sheet-metal preferably is overstretched about 48 mm on the support at the outside wall.
• the roof plates also lie with an overlap of the profile, which entails diagonal disc action at the same time as capillary flow of rain-water is avoided.
• the product development of the roof structure has resulted in a roof structure without combined roof trusses, which has the the advantage that it does not become equally dark indoors at the same time as the construction becomes cheaper.
• the eaves elements are suitably constituted by a thread part which is set on a protruding male beam or projec ⁇ ting extension of carcass flooring.
• the combination of ridge bent roofing sheet-metal and the roof structure which is threadable gives a unique overhung light roof, without either transverse sheet joint or perfora ⁇ ting through leads.
• the ridge bent roofing sheet-metal is only screwed in the profile crest in the lower edge of the sheet in the eaves element outside the wall web. As a result of the technique the characteristic "ticking sounds" from the roofing sheet-metal may be completely eliminated.

• Figure 8 shows a cross sectional view of a building with buckled roof.
• Figure 1 shows a gutter 10 consisting of a lower shank 12, a web part 14 and an upper shank 16.
• the web part 14 is designed with a downwards projecting part 18, which consti ⁇ tutes the gutter itself, and consists of an upper flank 20, a bottom part 22 and a web wall 24 opposite the inlet opening 23 of the gutter.
• In the bottom 22 at least an outlet pipe 26 is provided.
• the outlet pipe 26 can alternatively be provided in the lower part of the lower flank 24.
• the upper shank is double folded and consists of a top surface 28, a front surface 30 directed upwards along the roof and a lower surface 32 facing downwards against the surface of the roof.
• fasteners 40 with bolt holes 45 intended for fastening of the gutter on for instance the high leg 42 of the roof trusses.
• the ends of the gutter are covered by removable end pieces 33 provided with seals.
• the gutter according to the invention is particularly intended by overhung to hold the lower end of the roofing, for example trapeze-shaped roof plates 46 which are buckled against an underlay.
• Gutter hooks 34 which are arranged inside the gutter 10 form end stops for the roof plates and prevents them from sliding so far into the gutter that the water flow is hindered.
• the gutter hooks consist of a retainer part 36, a centre part 38 and a fastening part 39.
• the fastening part consists of a plane plate, bearing against the lower shank 12 and at the top exhibits an end hook 43 surrounding the upper edge of the shank 12. At the other end of the sheet there is found a hole 41 surrounding the centre part 38.
• the parts 36 and 38 consist of steel profiles welded together to L-shape.
• the steel profiles are suitably constituted by U-beams or square pipes. This is however no limitation, since the gutter hooks can have an arbitrary profile and consist of arbitrary material with sufficient strength.
• the gutter hooks can further be realized in one piece or be joined by another method than by welding. Even without welding the gutter hook holds together the gutter through cooperation between the retainer part 36 and the surfaces 28, 32 and prevents the gutter from being straigh ⁇ tened out by great snow loads.
• gutter hooks 34 instead of, or as a complement to the gutter hooks 34 one may use S-shaped hooks 47 intended to grip into the gutter valleys of the roof plates 46 and round the upper edge of the lower shank 12.
• the gutter hooks 34 are inserted from the gutter ends, while the hooks 47 also can be inserted through the aperture 23.
• the holds 40 are fixed by the downwards projec ⁇ ting high leg 42 of the roof trusses.
• a high leg of a square pipe is shown and the fastening part 40 is inserted in the same and held fixed by a bolt 44.
• a roof element, 46 of trapeze profile sheet-metal protrudes in between the lower shank 12 and the upper shank 16 and rests with its end 48 against the centre part 38 of the gutter hook. In this way it will be possible to fasten the roof panel at its lower end without making any holes in the same for nails or screws.
• the holds 40 can be fastened in an arbitrary way at the high legs 42. In those cases, when the roof includes a roof panel, the gutter 10 is instead attached with its lower shank 12 to this.
• the lower shank 12 of the gutter should be so long, that it extends above the level of the upper edge of the shank 16 shown with a broken line 50. In this way is preven ⁇ ted, that a possible stoppage in the outlet pipe 26 leads to water penetration into the roof panel and the inside of the house .
• FIG. 2 shows a second embodiment of the gutter according to the invention particularly provided to contain a cleaning tool 52 intended to remove twigs, leaves and other solid objects from the gutter 10.
• the web wall opposite the aperture 23 is divided into an upper web wall 24a and a lower web wall 24b, which form approximately 135° angle with each other.
• the wall 24a becomes essentially vertical and the lower web wall 24b together with the bottom part 22 form a flume, which is symmetrical about a vertical plane and has 45° wall tilt. Since the gutter is designed with a downwards projecting gutter part 18 it is possible to use it even at very flat roof slopes.
• This gutter at the both ends thereof is provided with a pulley 54 to take up a ' tug wire 56 for the cleaning tool 52.
• the pulley is fixed to the upper web wall 24a and an attachment 58 welded to said wall by means of a bolt 60.
• Figure 3 shows the cleaning tool 52. It consists of an angle iron with two sides 62. In the intermediate valley 64 two ears 66 are welded. The ears exhibit two holes 68 as alternative upper and lower fastening points respectively for two tug wires 56 intended for displacement of the cleaning tool from one end of the gutter..10 to the other and back.
• the walls of the cleaning tool are cut obliquely at both ends to form a point 70 intended as a plough point or a wooden plough to dig downwards under the trash that has gathered in the bottom 18 of the gutter and collect this between the sides 62 of the cleaning tool .
• the cleaning tool When using the cleaning tool at least one end piece 33 is first removed. Then the tool is drawn by means of the tug wire 56 by hand or with the help of a tug vehicle or hoist from one end of the gutter 10 to the other. Thereafter the cleaning tool is emptied and if needed it may pass a second time through the gutter in the opposite direction. After completed cleaning the cleaning tool 52 can be left in the gutter or coupled off from the wire 56 drawn into the gutter and be removed to another gutter for cleaning of the same. Of course one must see to it that a cleaning tool 52 left behind does not block any outlet pipe 26. This is made most simple by placing the outlet pipe 26 near the end of the gutter and give the sides 72 of the head 70 such inclination that the outlet pipe 26 can not be blocked by an end piece 33 on the gutter.
• the gutter according to the invention is made in rough goods in the gutter profile 10 itself, about 2 - 3 mm or thicker. Thereby it can support great snow and ice loads. For particularly great loads, long roof lengths or when the gutter at the same time is used as a frame element in the building the embodiment in figure 5 -7 is used.
• a gutter is shown, in which the inner gutter hooks ' 34 are constituted by a longitudinal square beam 76 and an angle iron 78 kept together by a number of middle parts 38.
• Fasteners 40 are provided on the square beam for connection to the roof trusses 42.
• the gutter 10 itself is here designed as a snap profile with recesses 80 for the fasteners 40.
• the lower free end is here at least partly down-bent with a capturing edge 82 over the square beam 76 and these together form the lower shank 12, against which the roofing sheet 46 rests.
• the lower leg 84 of the angle iron 78 here forms the end stop for the roofing sheet 46 and is wedged downwards against the underlay 76, 82 by means of a somewhat elastic filling part 86, for example a rubber strip or a wooden lath impregnated under pressure.
• a device according to the invention also can be used to hold the upper end of the roofing.
• the first embodiment is most adequate, since hardly any leaves are washed into the upper gutter and cleaning probably is not required.
• the gutters according to the invention may be used to buckle the roofing by overhung without need for this to be nailed in middle.
• the roof is held together and on site by means of diagonal stays, which extend between wire holds 51 on or in connection to the gutters 10.
• gutter as a roof plate holding eaves element for overhung roofing sheet
• diagonal staying wire device under the roofing sheet-metal between the ridge profile and on or in connection to the gutters and that the roofing sheet is set out with an overlap of at least one profile in order to obtain diagonal disc action makes that the whole roof structure becomes overhung and this without con ⁇ ventional roof trusses.
• whole roofing can be mounted without perforating through leads, that is without for example that the roofing sheet-metal needs to be screwed or be nailed up. Further the roofing sheet is over-stretched to avoid that the roofing sheet beats in hard wind.
