BACKGROUND
[0001] The present invention regards a barrier for a rain gutter.
[0002] A rain gutter, as used herein, is used to collect rain water from a roof and convey
the water to a vertical pipe leading the water to the ground. Thus, in the following
a rain gutter is any elongated vessel open at the top and having two lateral edges
facing upwards. The edge closest to the house is denoted the proximal edge, whereas
the edge further away from the house is denoted the distal edge.
[0003] Rain gutters can have different designs in different countries. In countries without
significant snow, the rain gutter can be mounted across an imaginary extension line
following a sloping roof top. In countries with significant amounts of snow, e.g.
the Nordic countries, rain gutters are mounted below this imaginary line, such that
snow slipping off the roof does not pull away the gutter. In these cases a protective
splash board is disposed between the gutter and the house to prevent water spilling
or splashing over the edge of the rain gutter from hitting the wall of the house.
The rain gutter can be attached to the splash board with suitable mountings.
[0004] A barrier can be disposed over the gutter in order to prevent leaves, needles from
e.g. fir or pine and other debris from falling into the gutter and clogging the vertical
pipe.
[0005] Barriers designed as nets or gratings curved by fittings are disclosed in e.g. German
utility patent application
9401192 U1, patent applications
DE 3804541 A1 and
EP 0 692 588 A1, as well as in
US patent nr 5 044 581. The barriers disclosed in the above documents are attached to both lateral edges
of the rain gutter. When the rain gutter is attached to a board, some of the debris
will slide down behind the barrier and be collected at the board.
[0006] JP 9279782 describes a rain gutter with a barrier manufactured as an integrated device. When
this device is attached to a vertical wall or board, the barrier has a curved fall
from the point of attachment to the distal edge of the gutter. The curved fall helps
leaves slipping past the gutter. An important disadvantage of this solution is that
post-installation of a barrier requires replacement of the entire gutter.
[0007] FR 2677695 discloses a barrier for rain gutters, the barrier having a smooth and curved shape
to ensure that leaves and other debris slips easily along. Viewed from the end in
a direction along the gutter, the sliding surface can be convex or concave.
[0008] WO 94/05874 describes a rain gutter system having a resilient fitting for two kinds of gutters
that are common in Canada. The fitting has an upper curved face with fixed hooks used
for attaching the barrier. The curved surface provides a curved fall from the wall
to the edge of the gutter. The fitting in
WO 94705874 requires that existing gutters are removed before it is mounted, and hence it is
useful for new gutters or during rehabilitation.
[0009] An object of the present invention is to provide a fitting for a barrier which can
be attached to a mounted rain gutter, regardless of where and how the gutter is mounted.
[0010] Another object of the present invention is to provide a fitting that easily can be
adapted to different rain gutter designs.
[0011] Yet another object of the present invention is to provide a mounting that enables
efficient removal of leaves, when at the same time preventing needles from falling
through to the rain gutter.
SUMMARY OF THE INVENTION
[0012] According to the invention, this is achieved by providing a fitting for a barrier
for a mounted rain gutter, the fitting having an upper curved surface with fixed hooks
for attaching a barrier, wherein the fitting is provided with a gutter attachment
adapted for attachment to a lateral edge of the rain gutter.
[0013] The curved shape causes debris to slip off the barrier easily, and ensures that the
debris falls on the outer side of the gutter. By attaching the fitting to a lateral
edge of a gutter, e.g. using a clamping mechanism, the fitting is easily adapted to
rain gutters having different shapes and/or designs.

DETAILED DESCRIPTION
[0015] Fig. 1 shows a rain gutter 320 mounted under roof such that sliding snow will be
able to pass over it, and such that rain water will be able to enter it. A splashboard
310 prevents water from splashing onto the wall behind. The gutter has a distal 321
and a proximal 322 lateral edge facing upwards. A curved fitting 100 holds a barrier
102 to prevent debris from falling into the gutter 320.
[0016] Fig. 2 illustrates a fitting 100 adapted to gutters of different size and design.
In Fig. 2a, an inset 122 adapts the lower end of fitting 100 to a first lateral edge
design. In Fig. 2b, the gutter is broader, and so the fitting 100 is extended by means
of two slidable parts 110 and 120, as described below.
[0017] Fig. 3a illustrates the different angles A
1 and A
2 between a vertical plane and the top surface of a fitting 100 near the distal lateral
edge of gutter 320a and 320b respectively. These different angles A
1 and A
2 must be accounted for when designing an attachment mechanism to be used with both
gutters 320a and 320b.
[0018] In Fig. 3b, angles B
1 and B
2 illustrates different sizes and/or shapes of lateral edges 321 a and 321 b respectively.
B
3 illustrated that a tangent of the gutter near the distal lateral edge 321 b may be
inclined with respect to the vertical. All of these angles must be accounted for when
designing an attachment mechanism to be used with both edges 321 a and 321 b.
[0019] Figure 4 is a detailed view of a first embodiment of a fitting according to the invention.
In particular, Fig. 4a, c and d illustrates a wall mount 111 which is used to fix
the upper end of this first embodiment to a substantially vertical plane, such as
a wall or splashboard 310 (Fig. 1). It is noted that this wall mount is optional.
Also, any means fit for rigidly fixing the upper end of fitting 100 to a vertical
wall may be employed. The use of a plate and screws is an example only.
Fig 4b is a top view of an upper part 110 of the fitting 100. Fig 4e is a side view
of the same part 110, which is slidably arranged with respect to a lower part of the
fitting 120 illustrated in Fig 4f. Latching means 131, 132, illustrated as a pin and
holes, may be used fir fixing the length of the assembled fitting 100, as shown in
Fig. 4g. It should be noted that the lower end 121 of the fitting 100 in all embodiments
are used to attach the fitting 100 to the gutter, and hence will be denoted a "gutter
attachment" in the following. As described below, the gutter attachment 121 may comprise
an adapter 122 or a clamping mechanism for securing the fitting 100, or a lower part
120 thereof, to a lateral edge 321 of the rain gutter 320.
[0020] Fig. 5 is a perspective view of the embodiment from Fig 4, also showing an example
adapter 122 for adapting the gutter attachment 121 to a lateral edge of a certain
gutter system. By using different adapters 122 for different gutter systems, one gutter
attachment 121 can be used with several gutter systems. This decreases the cost of
manufacture, as larger series of components may be made.
[0021] Figure 6a-c show the upper 110 and lower 120 parts of the embodiment from Fig. 4
viewed from the other side. It should be noted that while the embodiments have to
parts 110 and 120 slidably arranged with respect to each other, a fitting 100 without
slidable parts would also be possible.
[0022] Figure 6 also illustrates a curved slot adapted to receive an auxiliary net. For
example, an auxiliary fine masked net may be useful to prevent needles from e.g. fir,
pine etc from falling into the gutter in embodiments where the main barrier is a rather
coarse grating for moving leaves away as fast as possible: Small extending edges around
the holes in a grating, such as those created when punching holes through a metal
plate, tends to increase the speed of water streaming over the grating thus conveying
leaves and similar material away from the main grating.
[0023] Figure 7 shows lateral edges of various shapes from various example gutter systems.
One gutter attachment 121 can be used with all systems by using different adapters
or insets 122a-122d, or the gutter attachment 121 can be used without any adapter
as illustrated in Fig. 7a.
[0024] Figure 8 illustrates a different gutter attachment 121 in the form of a resilient
clamp. In this example embodiment, a lower clamping device 121 b, c is arranged around
the distal lateral edge 321. Then an end 121 a of the fitting 100 is inserted into
an upper slot formed by the two parts 121 b and c. a hook on part 121 b enters a notch
123 at the end 121 a of fitting 100, thus providing a pivot axis. As shown on Fig.
9, the end lower 121 a of the fitting 100 is shaped such that it forces the upper
ends of parts 121 b and 121 c apart when the fitting 100 is rotated about the pivoting
axis Z, e.g. by bringing the upper end of fitting 100 into contact with the wall or
splashboard 310 (Fig. 1). When the upper ends of parts 121 b and c are forced apart,
their lower end clamps firmly around the lateral edge 321 of the gutter, thus securing
the fitting to the gutter."
[0025] Figure 10 shows a second embodiment of a fitting 100. This embodiment does not use
a wallmount, and is entirely fixed by clamping to a gutter 320 as illustrated in Figs
8 and 9. The embodiment of Fig. 10 has two slidable parts 110 and 120 for accommodating
gutters of different width, Because the fitting 100 can be pivoted arouns the axis
Z running through notch 123, different angles C caused by gutter width (Fig 3a) and/or
shape (Fig. 3b) are accommodated.
[0026] When mounting a barrier with the fittings 100 according to the invention, a plurality
of fittings 100 are spaced apart along the distal lateral edge 321. The fittings may
be attached to the gutter, i.e. the lateral edge 321, in one piece as illustrated
in Figs. 4-7, possibly by using an adapter 122 for a specific gutter system. Alternatively,
the fittings 100, specifically the lower ends 121 a thereof, may be attached after
parts 121 b, 121 c are put in place on the lateral edge 321 as illustrated in Figs
8-10. The upper ends may optionally be attached to a vertical board 310. Also, an
auxiliary net may be put in place in slots 140 before the leaf barrier 202 is attached
to the fittings 100. Finally, it is noted that any means for attaching the barrier
to the fittings 100 are usable with the present invention, and that the use of hooks
at the upper face of the fitting as shown in the figures is by way of example only.
