Description

ROOF PENETRATION

BACKGROUND OF THE INVENTION

[0001] The invention relates to a roof penetration according to the preamble of claim 1 and particularly to a roof penetration comprising a base plate, a collar provided in the base plate and projecting upwards therefrom, and a connection part to be placed rotationally onto the collar for an outlet pipe.

[0002] In accordance with prior art, a roof penetration comprises a base plate that is suitable for the roof covering and installed onto an opening made in the covering in such a manner that it covers said opening in the covering. An opening is provided in the base plate for the insertion of a pipe or the like, and it is surrounded by a collar extending upwards from the surface of the base plate. The opening in the base plate is generally shaped round, substantially round or elliptical. In accordance with prior art, the collar is constructed to extend upwards from the base plate and to at least partly curve towards the centre of the opening, the collar thus forming a continuous curved surface. When the roof penetration is installed in position on the roof, particularly the section on the side of the lower edge of the base plate of the collar extends particularly curvedly upwards curving towards the upper edge of the base plate. This being so, the collar is usually higher and more curved on the side of the lower edge of the base plate than on the side of the upper edge. A connection part is further placed onto the collar, the connection part being shaped and dimensioned to substantially tightly and rotationally settle onto the collar. The connection part may also be a fixed part of an outlet pipe, ventilation conduit or other conduit, which extends upwards from the opening of the base plate and the coiiar and for which the penetration is provided.

[0003] A roof penetration of the above-described kind is installed on an inclined roof by installing the base plate at an opening in the roof. The connection part is further placed onto the collar of the base plate, the connection part being shaped to substantially tightly settle onto the collar in a manner allowing it to be rotated on the collar relative to the base plate and the collar. The aim is to always install the pipe extending above the roof upwards from the opening of the roof penetration in an as perpendicular position as possible irrespective of the inclination of the roof. For this reason, the connection part is rotated to the desired position on the collar relative to the base plate. In other words, the collar of the base plate and the connection part, which rotate relative to each other, constitute a joint by means of which the outlet pipe or the like extending above the roof is placeable into a perpendicular position irrespective of the inclination of the roof.

[0004] The problem in the above-described arrangement is that the perpendicular installation of the outlet pipe or the like is extremely difficult on the roof in practice, since the connection parts rotates on the collar in all possible directions. Furthermore, this being so, the installation of the connection part into the correct position consumes time and often the position of the connection part has to be corrected in order for the outlet pipe to definitely assume a perpendicular position.

BRIEF DESCRIPTION OF THE INVENTION

[0005] The object of the invention is thus to provide a roof penetration for solving the above problems. The object of the invention is achieved with a roof penetration according to the characterizing part of claim 1 , characterized in that the roof penetration further comprises guiding means that enable the rotation of the connection part placed onto the collar relative to the base plate in the direction of the pane of the roof when the base plate is installed in position onto the roof, and substantially prevent the rotation of the connection part relative to the base plate in a direction transverse to the direction of the pane of the roof.

[0006] Preferred embodiments of the invention are described in the dependent claims.

[0007] The invention is based on providing the roof penetration with guiding means that restrict the movement of the connection part, placed onto the coiiar of the base piate, allowing the connection part to turn substantially only in the direction of the pane of the roof. In this context, the direction of the pane of the roof refers to the direction from the eaves towards the ridge of the roof or the highest point of the roof or a given pane, which in most cases is a direction perpendicular to the eaves. The guiding means may by implemented for instance as a groove connection between the collar and the connection part, which enables the rotation of the connection part relative to the base plate and the collar therein, enabling rotation substantially only in the direction of the pane of the roof, and preventing rotation in a direction transverse to the pane. The guiding means may be implemented in a plurality of ways such that they enable the rotation of the connection part in the direction of the pane of the roof when the connection part is installed in position onto the collar in the base plate. At the same time, the guiding means prevent the connection part from rotating in a direction transverse relative to the pane of the roof and support the connection part in said transverse direction. These guiding means may be made up of features provided in both the base plate and/or the collar therein and the connection part or features provided only in the base plate and/or the collar therein or only in the connection part.

[0008] An advantage of the method and system of the invention is that the guiding means facilitate the positioning of the connection part in practice, whereby the installer only has to attend to a unidirectional straightness when installing the connection part into the desired position relative to the base plate, the roof and/or the perpendicular direction. In addition, since the connection part is conventionally fastened to the collar with fastening means, such as screws and the like, at its sides parallel to the pane, the lateral support of the connection part is weaker than the support in the direction of the pane. The use of the guiding means according to the invention also increases the lateral support of the connection part, preventing the lateral rotation or moving of the outlet extending from the penetration and the connection part in a direction transverse to the direction of the pane, when the roof penetration is installed in position on the roof.

[0009] In the following, the invention will be described in more detail in connection with preferred embodiments with reference to the accompanying drawings, in which

Figures IA and 1B show an embodiment of the present invention seen from slightly different viewing angles and with the base plate and the connection part separate;

Figure 2 shows the embodiment of Figures 1A and 1B with the connection part placed above the base plate; and

DETAILED DESCRIPTION OF THE INVENTION

[0010] Referring to Figures 1A and 1 B, they show an embodiment of a roof penetration of the present invention. Figures 1A and 1B show the same embodiment from a slightly different angle allowing all features of the embodiment to be seen. The roof penetration comprises a base plate 2 to be installed onto an opening provided in the roof for the penetration. The shape of the base plate 2 may vary freely according to the type and model of the roofing material in such a manner that the design of the base plate matches the roofing material and model in question. The base plate 2 further comprises an opening 20 through which a penetration pipe, a ventilation conduit, an outlet pipe or the like is inserted from the underside of the roof to the outside of the roof. In Figures 1A and 1B, the shape of said opening 20 is a rectangle having rounded edges, but it may also be of any other shape, such as round, square or elliptical. A collar 4 extends upwards from the edge of the opening 20. At its lower part, the collar 4 extends perpendicularly upwards relative to the plane of the base plate 2. At its upper part, at a distance from the base plate 2, the collar 4 is shaped to curve towards one end edge of the base plate 2, in this case an upper edge 22 of the base plate 2. The part on the side of a lower edge 21 of the base plate 2 of the collar 4 is made to extend and curve significantly farther than the part on the side of the upper edge 22 of the base plate 2 of the collar 4. This being so, the collar 4 is not symmetrical relative to the opening 20, but the collar 4 extends farther in the part on the side of the lower edge 21 of the base plate.

[0011] In accordance with Figures 1A and 1B, the sides on the side of the upper edge 22 and the lower edge 21 of the base plate 2 of the collar 4 are provided with a corresponding groove 11, 10 that opens to the outside of the collar 4 and extends from the upper edge of the collar 4 all the way to the lower edge. The sides 12 of the collar 4 parallel to the pane of the roof are further shaped at least partly planar and straight.

[0012] The roof penetration 1 further comprises a separate connection part 6 to be placed onto the collar 4. The connection part 6 is annular and a hole 30 in the centre thereof is shaped to correspond to the shape of the outer surface of the collar 4. Opposite sides inside the connection part are provided with ribs 8 and 9 arranged to fit into the grooves 10 and 11 of the collar 4. The connection part 6 further comprises planar straight side edges 14 parallel to the direction of the pane of the roof and shaped to correspond to the corresponding sides 12 of the collar 4. The connection part 6 further comprises shapes that enable the fastening of the outlet (not shown) thereto. The outlet may be e.g. an outlet pipe, a ventilation conduit or a corresponding structure to be inserted through the roof.

[0013] The collar 4 and the connection part 6, shaped in the above- described manner, are superimposable in the manner shown in Figure 2. In this case, the connection part 6 is placed onto the collar in such a manner that the rib 8 on the inner surface of the connection part 6 settles into the groove 10 on the outer surface of the collar 4 and, correspondingly, the rib 9 (see Figure 3) on the inner surface of the connection part 6 settles into the groove 11 on the outer surface of the collar 4. This being so, the opening 20 of the base plate 2 and the opening 30 of the connection part are placed to match, thus forming a penetration opening, through which the outlet can be led through the roof.

[0014] Figure 3 shows the connection part 6 installed onto the collar 4 in a manner allowing the sides of the connection part 6 to settle around the collar 4. When the connection part 6 is placed onto the collar 4 in the presented manner, it may be rotated relative to the collar 4, the base plate 2 and the roof in a direction defined by the grooves 10, 11 and the corresponding ribs, the direction being the direction of the pane of the roof. Thus, the connection part 6 only rotates in one direction in the direction of the pane of the roof. Roofs are usually inclined in the direction of the pane, whereby the solution of the present invention enables the rotation of the connection part 6 and the outlet to be installed therein to a perpendicular position in the direction of the pane of the roof irrespective of the inclination of the roof. This facilitates the perpendicular placement of the connection part 6, since the ribs 8 and 9 extending in the grooves 10 and 11 guide the rotation of the connection part 6 relative to the base plate and the roof. The groove joint also simultaneously supports the connection part in a lateral direction transverse relative to the pane of the roof and said grooves. For the operation of the groove joint in controlling the rotation of the connection part 6 and enhancing lateral support, the corresponding sides 12 and 14 of the collar 4 and the connection part are arranged as planar surfaces that extend in the direction of the pane of the roof in the same manner as the grooves 10, 11 and the ribs 8, 9, i.e. parallel thereto. These sides 12 and 14 also support the connection part laterally.

[0015] In accordance with the invention, the guiding means for controlling the rotation and support of the connection part and, consequently, also the outlet, may be achieved also in some other suitable manner. For example, the ribs may be replaced with pins or other cut-to-size projections. Similarly, the grooves may be replaced with depressions or holes or cut-to-size recesses that fit into the pins and restrict the rotation of the connection part to desired areas. Alternatively, the grooves or other recesses may be provided also in the connection part and, correspondingly, the ribs or other projections in the collar. Furthermore, the connection part may be an integral part of the outlet, such as an outlet pipe or ventilation conduit.

[0016] In addition, the guiding means may comprise at least one control surface provided in the collar and at least one mating part or mating surface provided in the connection part, which is placeable against the control surface and enables the rotation of the connection part relative to the base plate in the direction of the pane of the roof and substantially prevents the connection part from rotating relative to the base plate in a direction transverse relative to the direction of the pane of the roof. The control surface may also be in the connection part and the mating surface in the collar. Alternatively, the guiding means may be provided in the sides 12 and 14 of the collar and the connection part in the direction of the pane. Furthermore, there may be one or more guiding means, such as groove joints.

[0017] The material of the base plate, the collar and the connection part is preferably a plastic material, but composite materials, metals, sheet metal or another suitable material may be employed therein. The connection part, the base plate and the collar may also be made from mutually different materials.

[0018] The roof penetration further comprises fastening means by means of which the connection part may be fastened to its desired position relative to the roof and the base plate. For example, the fastening means may be holes that are provided in the sides 14 and 12 of the connection part 6 and the collar and through which screws, nails or the like may be inserted. The fastening means may also be a pivot connection or another similar arrangement that locks the connection part 6 to the collar 4 or the base plate 2.

[0019] It is obvious to a person skilled in the art that as technology advances, the basic idea of the invention can be implemented in a variety of ways. Consequently, the invention and its embodiments are not restricted to the above examples, but can vary within the scope of the claims.
