JOINABLE SHEET METAL PROFILE FOR ROOF GABLE END
The invention relates to a sheet metal profile (9a,b, 19a,b, 22a,b, 23a,b, 24a,b, 25) primarily intended for installation against parts of a building, for example for the protection of bargeboards (2) or other wooden component parts of the building, comprising a bent metal sheet having a central section and at least one lateral part (3a,b) with inward-folded edge sections (15a,b) at the bottom. The invention is achieved by the sheet metal profile (9a,b, 19a,b, 22a,b, 23a,b, 24a,b, 25) being of mirror symmetrical configuration at both end sections (11a,b, 17, 21a,b), and by the end sections (11a,b, 17, 22a,b) being provided with an inward-facing edge (13a,b, 21a,b) cut at an angle, that is to say one or both lateral parts (10a,b, 20a,b) of the sheet metal profile (9a,b, 19a,b, 22a,b, 23a,b, 24a,b, 25) are executed with angled end edges (13a,b, 21a,b), where the angle (v) between the upper plane surface (12) of the sheet metal profile (9) and the end edges (13a,b, 21a,b) of the lateral parts form an acute angle (v).
The present invention relates generally to sheet metal elements or sheet metal profiles for use in covering parts of buildings. The invention relates in particular to sheet metal profiles that are intended to be joined in the longitudinal direction and are accordingly configured at their end areas so that a waterproof, durable, functional and neatly executed joint is obtained when a plurality of sheet metal profiles are installed next to or after one another.
BACKGROUND ARTWhen covering a roof, for example, it is customary to install transverse planks of wood at the gable ends of the roof and for these to constitute the bargeboards of the roof. The gap or opening that occurs between the roof covering material and the bargeboards is often covered/bridged with the help of profiled sheet metal covers or so-called bargeboard covers, which are bent down on both sides about a raised central section, which central section is positioned above the upper side edge of the bargeboard; see
One way of avoiding this problem is not to make the cut-outs in the cover that are normally required in order to achieve good contact between two covers that are to be joined together, so that waterproof joints can be achieved, yet still allowing the covers to overlap one another regardless of whether the installation is right-handed or left-handed. This results in a poor fit between the component parts and the possibility of a leaking joint occurring. In addition, such a joint is visually conspicuous and untidy.
DISCLOSURE OF INVENTIONOne object of the invention is to solve the problems outlined above and to propose a sheet metal profile which, when installed and joined to other sheet metal profiles, gives a waterproof, durable and visually neat joint that is fit for purpose, regardless of whether they are installed as a right-hand or a left-hand profile on part of a building.
A further object of the invention is to simplify the manufacture and thus to reduce the production costs by reducing the number of different sheet metal profiles, as well as the volume of sheet metal profiles, that require to be manufactured and kept in stock, which also reduces the cost of storage and the storage area required by manufacturers, distributors, shops and tradesmen.
A further object of the invention is to propose a sheet metal profile which reduces the risk of ingress of water and corrosion.
A further object of the invention is to eliminate or to reduce the risk of incorrect deliveries or incorrect manufacture of the number of sheet metal profiles required for right-hand and left-hand installation and thereby to reduce the need for transport of these components, which also has a positive effect on the environment.
A further object of the invention is also to enable a person who is not skilled in the art to install sheet metal profiles without specialist knowledge and without professional tools and still to achieve a waterproof and visually neat joint that is fit for purpose.
The above-mentioned and additional objects and advantages are achieved according to the invention with the help of a sheet metal profile configured in accordance with the distinctive features indicated in the characterizing part of Patent Claim 1.
The invention thus relates to sheet metal profiles that are configured with angled or notched end walls so that they can overlap other corresponding sheet metal profiles without requiring to be pushed into special tracks therein and without the need for specially configured recesses or cut-outs which make manufacture and installation difficult and mean that installation takes a longer time because the profiles can become tightly wedged in one another in conjunction with joining, among other things due to friction and/or the stick slip effect. One sheet metal profile according to the invention is provided with downward-folded lateral parts, of which the end walls are cut at an acute angle in relation to the upper plane surface of the sheet metal profiles. The angle between the upper surface and the end edge of the lateral parts is preferably approximately 45 degrees, although it can, of course, be larger or smaller. A small part, preferably approximately 1 cm, of the lowest edge of the lateral parts is folded up towards the inside of the sheet metal profile in order to reinforce the bottom edge. This permits good contact between joined profiles, and if, for example, an angle of 45 degrees is used for the oblique cut, the upward-folded edges form a stop for two sheet metal profiles when they are joined together. If the end walls of the sheet metal profiles are punched, it is also easy to form a tongue on each upward-folded edge, which is able to some extent to overlap/cover a part of neighbouring sheet metal profiles and, by so doing, to lock the profiles to one another.
Further distinctive features and advantages of the invention can be appreciated from the following, more detailed description of the invention and from the accompanying drawings and the other patent claims.
The invention is described below in more detail as a number of preferred illustrative embodiments with reference to the accompanying drawings.
The invention relates to a sheet metal element or a sheet metal profile intended for installation against parts of a building and relates to, among other things, sheet metal profiles intended for covering, for example, bargeboards on roofs. The invention relates in particular to the configuration of the end areas of the sheet metal profiles, so that only one variant of a sheet metal profile is required, regardless of whether they are intended for left-hand or right-hand installation. The sheet metal profiles must also be capable of being joined to one another in such a way that a durable, waterproof, functional and visually neat joint is produced between the sheet metal profiles.
The above description is intended in the first instance to facilitate the understanding of the invention. Therefore, the invention is naturally not restricted solely to the one or more indicated embodiments, but other variants of the invention are also possible and conceivable within the scope of the idea of invention and the scope of the protection afforded by the subsequent patent claims. Thus, it is of course possible to configure other similar sheet metal profiles with end sections cut at an angle.
