Description
-1- Corner Piece, Blank and Method for Manufacturing the Same, and Method for Providing a Corner in a Rain Gutter or Roof Trim
[01] The invention relates to a corner piece for joining together first and second stretches, especially first and second straight stretches, of roof gutter or roof trim at a connection angle to provide a corner in a rain gutter of a building. The invention further relates to a blank for manufacturing such a corner piece, a method for manufacturing such corner piece, and a method for providing a corner in a roof gutter or roof trim.
[02] Rain gutters or roof trims of buildings can be assembled on location by combining various pre-manufactured stretches of gutter or roof trim, which are generally made of zinc plate or galvanized (zinc-cladded) plate. To provide a corner in the rain gutter or roof trim, the respective ends of two stretches of gutter or roof trim are cut to respective shapes that should match one another in the corner and subsequently both ends are brazed together.
[03] However, it is quite difficult to provide matching ends of the stretches of gutter or roof trim. Furthermore, the stretches of gutter or roof trim may experience mechanical stress when mounted, which causes them to deform. Such deformation results in the respective ends of the stretches of gutter being dislocated with respect to one another, which causes even more difficulties to connect them together. Brazing or soldering both stretches together proves to be quite cumbersome, which can result in drops of solder dropping down on the person performing the soldering job. As a result, the corner made in the rain gutter may have a quite rough and untidy appearance.
[04] lt is an objective of the invention to allow a straightforward joining together of stretches of gutter at a connection angle to provide a corner in a rain gutter of a building.
[05] It is another objective of the invention to allow making a tidy and attractive corner in a rain gutter of a building.
[06] At least one of the above objectives is achieved by a corner piece for joining together first and second stretches, especially first and second straight stretches, of gutter or roof trim at a connection angle enclosed between respective longitudinal directions of the first and second stretches of gutter or roof trim to provide a corner in a rain gutter or roof trim of a building, the corner piece comprising: - a first corner piece part having a cross-sectional shape transverse to a longitudinal direction of the first corner piece part to allow sliding over an end portion of the first stretch of gutter or roof trim, along and in a direction transverse to the longitudinal direction of the 40 first stretch of gutter or roof trim, and holding the end portion of the first stretch of gutter or
-2- roof trim at, in use of the corner piece, an outside of the corner provided in the rain gutter or roof trim, the longitudinal directions of the first corner piece part and the first stretch of gutter or roof trim, in use, being parallel to one another; and - a second corner piece part having a cross-sectional shape transverse to a longitudinal direction of the second corner piece part to allow sliding over an end portion of the second stretch of gutter or roof trim, along and in a direction transverse to the longitudinal direction of the second stretch of gutter or roof trim, and holding the end portion of the second stretch of gutter or roof trim at, in use of the corner piece, an outside of the corner provided in the rain gutter or roof trim, the longitudinal directions of the second corner piece part and the second stretch of gutter or roof trim, in use, being parallel to one another, wherein the first and second corner piece parts are connected to one another to define a corner piece angle enclosed between their respective longitudinal directions, which is equal to the connection angle. The corner piece straightforwardly allows for providing the required connection angle in the roof gutter or roof trim and for a tidy appearance of the corner. It enables to work in a safer manner, especially when working at heights, with less probability for injuries and accidents. Especially when brazing parts together for the known methods for providing a corner in a roof gutter or roof trim, hot braze material may very well drop down on the workman making the corner due to practical difficulties in keeping and brazing the parts together. The corner piece and associated method according to the invention allows to work to be easier, but also faster and with a much better end result.

[22] The first embodiment of a corner piece 100 according to the invention shown in figures 1A and 1B comprises a first corner piece part 110 and a second corner piece part 120. The first and second corner piece parts 110, 120 of the corner piece 100 are each configured to hold an end portion of a first stretch of gutter G10 and of a second stretch of gutter G20, respectively. Generally, the stretches will be straight stretches, which is not part of the invention, but given by the actual circumstances in which the corner piece is employed. The first and second corner piece parts 110, 120 are connected to one another such that the first and second stretches of gutter G10, G20 are joined by the cutter corner piece 100 at a connection angle A to provide a corner in a rain gutter. The connection angle A is enclosed between respective longitudinal directions L10, L20 of the first and second stretches of gutter. The first and second stretches of gutter G10, G20 are shown in thin lines in figure 1A, whereas the corner piece 100 is shown in thick lines. The rain gutter will be mounted to a building B, which is schematically shown in figure 1B. An inside | of the corner is directed towards the building B, and an outside O of the corner is directed away from the building.
[23] The corner piece is made from a single piece of plate material, of which the first and second corner piece parts 110, 120 are parts. The first corner piece part 110 has a cross-sectional shape transverse to a longitudinal direction L110 of the first corner piece part to allow sliding over an end portion of the first stretch of gutter G10, along and in a direction transverse to the longitudinal direction L10 of the first stretch of gutter. The cross-sectional shape is further such that the first corner piece part holds the end portion of the first stretch of gutter when provided over the end portion at, in use of the corner piece, an outside O of the corner C provided in the rain gutter. The inside | of the corner C is at the corner side 40 facing the building B. The longitudinal directions L10, L110 of the first corner piece part and
-7- the first stretch of gutter, in use, are parallel to one another. In the same fashion, the second corner piece part 120 has a cross-sectional shape transverse to a longitudinal direction L120 of the second corner piece part to allow sliding over an end portion of the second stretch of gutter G20, along and in a direction transverse to the longitudinal direction L20 of the second stretch of gutter. The cross-sectional shape is again such that the second corner piece part holds the end portion of the second stretch of gutter when provided over the end portion at, in use of the corner piece, an outside O of the corner C provided in the rain gutter. The longitudinal directions L20, L120 of the second corner piece part and the second stretch of gutter, in use, are parallel to one another. The first and second corner piece parts 110, 120 are connected to one another with a corner piece angle a enclosed between their respective longitudinal directions, which comer piece angle a is equal to the connection angle A between the longitudinal directions L10, L20 of the stretches of gutter.
[24] The cross-sectional shape of the first and second corner piece parts 110, 120 is configured to enclose the respective end portions of the first and second stretches of gutter G10, G20, respectively, to constrain movement thereof in respective first and second mutually opposing directions D1, D2, which are depicted in figure 1B as upward and downward directions, respectively, Movement is further constrained in a respective third direction D3 perpendicular to the respective first and second directions D1, D2, which is an outward horizontal direction as depicted in figure 1B. The respective first, second and third directions D1, D2, D3 are perpendicular to the longitudinal direction of the respective first or second stretch of gutter.
[25] The corner piece 100 is made from a single piece of plate material, and a blank 101 of such a single piece of plate material is shown in figure 1C for the corner piece depicted in figures 1A and 1B. The blank 101 for making the corner piece 100 has a first blank part 130 having a first planar blank part portion 131 and a first further blank part portion 1324 that is connected to the first planar blank part portion. Further, the blank has a second blank part 140 having a second planar blank part portion 141 and a further second further blank part portion 1424 that is connected to the second planar blank part portion. The first and second planar blank part portions 131, 141 are adjacent and connected to one another by connection in the single piece of plate material as indicated by dashed line 101a in figure 1C. The first and second further blank part portions 1324, 1424 are located at corresponding sides of the first and second planar blank part portions 131, 141, respectively, and are not mutually connected but define a cut-out 1504 there between. The further blank part portions and the cut-out allow configuring the blank to provide the gutter corner piece 100 of figures 1A and 1B.
[26] In a method for manufacturing the corner piece 100 of figures 1A and 1B, the blank 101 of figure 1C is provided, and the blank is shaped to provide the corner piece. The first corner piece part 110 is configured from the first blank part 130, and the second corner piece part 120 is configured from the second blank part 140. The first and second further 40 blank part portions 132a, 142a are bend with respect to the respective planar blank part
-8- portion 131, 141 of the single piece of plate material to define the first and second corner piece parts 110, 120, respectively. Subsequently, the first and second blank part portions 1324, 1424 are connected by a joining connection like a welding or brazing connection. In the embodiment shown, the plate material comprises zinc, for instance, the plate material being a zinc plate or a galvanized (zinc-cladded) plate. The first and second blank part portions 1324, 142, in such embodiment, after bending, can be connected by brazing with the use of a zinc brazing material, which has been done in the embodiment shown. The connected portions of the first and second corner piece parts 110, 120 define a continuous Surface.
[27] The dotted line 1014 shown on the blank 101 of figure 1C corresponds to the dashed line 100a shown on the corner piece 100 of figure 1A. The first and second corner piece parts 110, 120 comprise first and second planar corner piece part portions 111, 121, respectively, which are adjacent and connected to one another by connection in the single piece of plate material along the dashed line 100a. In the first embodiment the first and second planar corner piece part portions 111, 121 actually form a single planar portion of the corner piece.
[28] To provide a corner in a rain gutter, first and second stretches of gutter G10, G20, which are to be connected at the connection angle A, and the corner piece 100 are provided. An end of the first stretch of gutter G10 is provided into the first corner part 110 of the corner piece, and an end of the second stretch of gutter G20 is provided into the second corner part 120. Subsequently, the corner piece part 100 and the first and second stretches of gutter G10, G20 are brazed together to provide a firm connection between the stretches of gutter. A connection angle A that is equal to the corner piece angle a is now present between the connected stretches of gutter. The figures show the connection angle A and the corner piece angle a to be 90 degrees, but they can have any applicable value given by the circumstances at hand.
[29] Figures 2A, 2B and 2C show a second embodiment of a corner piece 100 and a blank 101 for configuring such a corner piece. The corner piece and blank of the second embodiment largely correspond to the ones of the first embodiment. In the second embodiment, the first and second planar corner piece part portions 111, 121 are folded along the line 100a with respect to one another in the single piece of plate material. Correspondingly, the first and second planar blank part portions 131, 142 are folded with respect to one another when manufacturing the corner piece 100. In use, the first and second planar corner piece part portions 111, 121 of the second embodiment are in a slanted position, as is clearly visible in figure 2B. Additionally, the corner piece 100 and corresponding blank 101 are shown to have first and second corner piece and blank parts 110, 130, 120, 140 that are leg parts in the corner piece and blank, respectively. The constrained first, second and third directions D1, D2, D3 are slanted with respect to the corresponding constrained directions of the first embodiment. Further, in the assembly of 40 the stretches of gutter G10, G20 connected to one another by the corner piece 100 as shown
-9- in figure 2A, the portions of the end portions of the stretches of gutter covered by the corner piece 100 do not extend up to one another. They leave an open corner covered by the corner piece.
[30] Figures 3A, 3B and 3C show a third embodiment of a corner piece 100 and a blank 101 for configuring such a corner piece. The corner piece of the third embodiment is for joining together first and second (straight) stretches of roof trim R10, R20 at a connection angle A enclosed between respective longitudinal directions L10, L20 of the first and second stretches of roof trim to provide a corner C in the roof trim of a building B. In the third embodiment, the planar corner piece part portions 111, 121 of the first and second corner piece parts 110, 120 are folded with respect to one another in a single piece of plate material along the line 100a. The planar blank part portions 131, 141 of the first and second blank parts 130, 140, respectively, of the blank 101 are folded with respect to one another along the dashed line 101a when manufacturing the corner piece. The first blank part 130 of the blank 101 has first further blank part portions 132a, 132b, and the second blank part 140 has second further blank part portions 142a, 142b. Corresponding first and second further blank part portions 132a, 142a, 132b, 142b at corresponding sides of the first and second planar blank part portions 131, 141, respectively, are not mutually connected but define a respective cut-out 150a, 150b there between to allow configuring the blank to provide the corner piece 100. The first and second further blank part portions 132a and 142a are at a first corresponding side, and the first and second further blank part portions 132b and 142b are at second corresponding side opposing the first corresponding side of the blank. The first and second further blank part portions 132a and 142a are bend, and the first and second further blank part portions 132b and 142b are folded when configuring the blank to provide the corner piece part. Subsequently, the first and second further blank part portions 132a and 142a are connected by a joining connection, such as welding or brazing as described earlier. The first and second further blank part portions 132b and 142b are not connected by a joining connection in the embodiment shown. Movement of the respective end portions of the stretches of roof trim is constrained in opposing first and second directions D1 and D2 that are oriented vertically, and in a third direction D3 that is oriented horizontally outward. The first and second further corner piece part portions 112a, 122a, 112b and 122b correspond to the first and second blank part portions 132a, 142a, 132b and 142b, respectively.
[31] Figures 4A, 4B and 4C show a third embodiment of a corner piece 100 and a blank 101 for configuring such a corner piece. The corner piece of the third embodiment is for joining together first and second (straight) stretches of roof trim R10, R20. The fourth embodiment resembles the third embodiment. However, the corner piece of figures 4A and 4B does have corresponding first and second further corner piece part portions 132a and 142a at only one side of the planar corner piece part portions 131 and 141, respectively, which are shaped such as to constrain movement of the stretches of roof trim R10, R20 in 40 the directions D1, D2 and D3 shown. The opposing first and second directions D1 and D2
-10 - are oriented horizontally, while the third direction D3 is oriented vertically.
The corresponding blank 101 shown in figure 4C is shaped accordingly to allow configuring the corner piece of figures 4A and 4B.
