Abstract

The invention relates to a sheet metal profile (9 a,b, 19 a,b, 22 a,b, 23 a,b, 24 a,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 (3 a,b) with inward-folded edge sections (15 a,b) at the bottom. The invention is achieved by the sheet metal profile (9 a,b, 19 a,b, 22 a,b, 23 a,b, 24 a,b, 25) being of mirror symmetrical configuration at both end sections (11 a,b, 17, 21 a,b), and by the end sections (11 a,b, 17, 22 a,b) being provided with an inward-facing edge (13 a,b, 21 a,b) cut at an angle, that is to say one or both lateral parts (10 a,b, 20 a,b) of the sheet metal profile (9 a,b, 19 a,b, 22 a,b, 23 a,b, 24 a,b, 25) are executed with angled end edges (13 a,b, 21 a,b), where the angle (v) between the upper plane surface (12) of the sheet metal profile (9) and the end edges (13 a,b, 21 a,b) of the lateral parts form an acute angle (v).

Description

TECHNICAL FIELD

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 ART

When 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 FIG. 1. This downward bending is provided to guide the runoff from the cover and to protect the bargeboard from moisture. Because the bargeboard covers are supplied in standard lengths, usually in two-metre lengths, they must be joined together in conjunction with their installation on buildings whose bargeboards exceed this length, which is usually the case. Because the bargeboard covers exhibit different bending on the inside and the outside, with different angles, and because they must be overlapped in conjunction with joining in order to be waterproof, so that water does not run in underneath the cover installed in the lowest position, the bargeboard covers must be manufactured in two configurations, one for right-hand and one for left-hand installation. This requires both forms to be manufactured and kept in stock by the manufacturer, the supplier and in the shop. This takes up a certain amount of storage space with associated storage costs. It is also necessary at the time of delivery to keep a close check on the number of right-hand and left-hand profiles to be delivered and installed. Unfortunately, incorrect deliveries often occur in practice, or the orderer may be mistaken in the number of covers of the different configurations to be used in the installation. This involves returns and increased handling costs and delays the installation.
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 INVENTION

One 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.

MODE(S) FOR CARRYING OUT THE INVENTION

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.
FIG. 1 depicts, in accordance with the prior art, a bargeboard cover 1, viewed from one of its end walls. The sheet metal profile 1 is intended for installation over a bargeboard 2, for example made of wood, by screwing or nailing into the upper plane horizontal surface of the bargeboard 2 or into the lateral parts of the bargeboard 2. The sheet metal profile 1 is provided with downward-bent lateral parts 3 a,b, of which one lateral part 3 a is intended to be installed on the outer side of the bargeboard 2, that is to say the side which faces away from the covering of the roof, and of which the other lateral part 3 b is intended to be connected to the covering of the roof, for example to roofing tiles, roofing sheets or similar (not illustrated). The outer/lower edges 4 a,b of the lateral parts 3 a,b are provided with upward-folded reinforcing edges or sections 5 a,b.
FIG. 2 depicts, in accordance with the prior art, two sheet metal profiles 1 a,b prior to joining viewed obliquely from the side. The sheet metal profiles 1 a,b are of different configuration at their end walls 6 a,b. Both end walls 6 a,b are cut straight across at an angle of 90 degrees in relation to the envisaged longitudinal axes of the profiles 1 a,b. Arranged on one end wall 6 b, however, are cut-outs 7, one on each edge. These cut-outs 7 allow this profile 1 a to be pushed into a second, corresponding sheet metal profile 1 b, and more precisely into the tracks that are formed by the upward-folded reinforcing edges or the parts 5 a,b. The cut-outs 7 are usually located at a distance of approximately 10 cm from the end wall of the sheet metal profile and permit the sheet metal profiles 1 a,b to overlap one another by approximately 10 cm. The fact that the sheet metal profiles are cut straight across and have straight end walls permits water to enter between the sheet metal profiles 1 a,b, among other things through capillary force, which can give rise to corrosion in the longer term, especially if the sheet metal profiles 1 a,b have been scratched or damaged in some other way during transport or during installation, which is a relatively common occurrence.
FIG. 3 depicts, also in accordance with the prior art, the two sheet metal profiles 1 a,b in the joined position, viewed obliquely from the side. The joint 8 is straight and perpendicular, at 90 degrees, in relation to the envisaged longitudinal axis of the sheet metal profile, and the sheet metal profiles 1 a,b are a good fit with one another thanks to the cut-outs 7 at the end wall of one of the sheet metal profiles 1 a. However, the presence of these cut-outs 7 and the fact that the lateral parts 3 a,b of the sheet metal profiles 1 a,b are of different configuration on the inside and the outside respectively of the sheet metal profiles means that sheet metal profiles 1 a,b for right-hand and left-hand installation must be manufactured, kept in stock and handled.
FIG. 4 depicts a side view of a sheet metal profile 9 according to the invention, in this case a bargeboard cover. It can be appreciated from the figure that the lateral parts 10 a,b of the sheet metal profile 9, of which only the lateral part 10 b is visible in this figure, are provided at both of their end sections 11 a,b with an end edge 13 a,b cut at an angle, which is cut inwards, that is to say so that the upper plane surface 12 of the sheet metal profile 9 forms a projecting part in both directions and one or both lateral parts 10 a,b of the sheet metal profile 9 are configured with an angled end edge 13 a,b, where the angle v between the upper plane surface 12 of the sheet metal profile 9 and the end edge 13 a,b of the lateral parts forms an acute angle v. The sheet metal profile 9 is also of mirror symmetrical configuration at both end sections 11 a,b, and the angle v of the end edge 13 a,b in relation to the upper plane surface 12 of the sheet metal profile 9 is approximately 45 degrees at this point. This angle v can be either larger or smaller than 45 degrees, although it should preferably lie within the interval of 30-60 degrees.
FIG. 5 depicts in a side view, viewed obliquely from above, two sheet metal profiles 9 a,b according to the invention, in this case bargeboard covers, which are in the process of being joined together. Any sheet metal profile 9 a,b at all can overlap the other sheet metal profile 9 a,b thanks to the configuration of the end section 11 a,b. One and the same sheet metal profile 9 a,b can thus be utilized both for right-handed and for left-handed installation, and only a single variant of the sheet metal profile 9 a,b is necessary. This reduces the production cost and the cost of storage, transport and handling.
FIG. 6 depicts a side view, viewed obliquely from above, of the two bargeboard covers 9 a,b according to the invention in the joined position according to FIG. 5. In this case, the right-hand sheet metal profile 9 b overlaps the left-hand sheet metal profile 9 a. Thanks to the lateral parts 10 a,b that are cut at an angle, a joint with a good fit and contact between the sheet metal profiles 9 a,b is achieved, which provides a waterproof and visually neat joint.
FIG. 7 depicts the two bargeboard covers 9 a,b according to the invention joined together according to FIG. 6, but viewed from below in this case. It is evident from this how the inward-folded edges 15 a,b on the right-hand sheet metal profile 9 b constitute an exact space to accommodate the left-hand sheet metal profile 9 a, so that the profile material in the sheet metal profiles 9 a,b can lie fully against one another after installation and do not form a gap or a space between the profile surfaces.
FIG. 8 depicts an alternative variant of a sheet metal profile 16 according to the invention. In this case, the end walls 17 of the sheet metal profile have been punched out and configured with tongues 18 a,b or locking plates which permit one of the sheet metal profiles 9 a to be pushed in to some extent into the second sheet metal profile 9 b, thereby achieving a guiding and retaining effect. This facilitates installation and keeps the sheet metal profiles 9 a,b next to one another when they are screwed or nailed in place, for example to a bargeboard (not illustrated here).
FIG. 9 depicts another embodiment of sheet metal profiles 19 a,b, viewed obliquely from the side, being in this case so-called roof end plates, with the end edges 21 a,b of the lateral profiles 20 a,b cut at an angle. The figure depicts two sheet metal profiles 19 a,b which are in the process of being assembled together.
FIG. 10 depicts the roof end plates 19 a,b according to FIG. 9, but viewed from below in this case.
FIG. 11 depicts a further embodiment of sheet metal profiles 22 a,b, in this case two upper tinplates prior to joining, viewed from below.
FIG. 12 depicts a further embodiment of sheet metal profiles 23 a,b, in this case two stand-up sheets prior to joining, viewed from below.
FIG. 13 depicts a further embodiment of sheet metal profiles 24 a,b, in this case two ridge caps prior to joining, viewed from below.
FIG. 14, finally, depicts yet a further embodiment of a sheet metal profile 25, in this case a window ledge, viewed from below.
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.
