will be further understood that the drain assemblies of the present
invention may be used without any other systems.
[0021] Referring now to FIGS. 1, 2, and 3, one embodiment of a
drain assembly is illustrated. The drain assembly 12 has a portion
20. The portion 20 has a first sheet 22 having drainage features 24
and a second sheet 26 having drainage features 28. The first sheet
22 has a first face 21 and a second face 23, and one of the first
or second faces 21, 23 has the drainage features 24 provided
thereon. The second sheet 26 has a first face 25 and a second face
27, and one of the first or second faces 21, 23 has the drainage
features 28 provided thereon. The first sheet 22 and the second
sheet 26 are disposed such that at least a portion of one of the
first or second faces 21, 23 of the first sheet 22 is parallel to
at least a portion of one of the first or second faces 25, 27 of
the second sheet 26. Additionally, the drain assembly 12 has fabric
32 provided over at least a portion of the first and second sheets
22, 26.
[0022] The drainage features 24, 28 may be any suitable drainage
features. In one example, the drainage features 24, 28 are dimples
in the first sheet 22 or second sheet 26. The dimples 24, 28 may be
of any suitable dimension and shape. For example, the dimples 24,
28 may be conical, pointed, or rounded dimples. The first sheet 22
and the second sheet 26 may be of any suitable material. For
example, the first sheet 22 and the second sheet 26 may be a
plastic sheet used in strip drain applications that contains
drainage features 24, 28. The first sheet 22 and the second sheet
26 can comprise separate sheets. Alternatively, the first sheet 22
and the second sheet 26 can comprise a single sheet that is bent to
provide the appropriate configuration.
[0023] Referring to FIGS. 1 and 2, in accordance with embodiments
of the invention, the portion 20 has a separator sheet 30 that is
disposed between the first sheet 22 and the second sheet 26. The
separator sheet 30 may be any suitable sheet having any suitable
dimensions. In one example, the separator sheet 30 may be a plastic
sheet. In one example, the drainage features 24 on the first sheet
can be dimples disposed such that the first sheet 22 first face 23
has depressions and the first sheet 22 second face 25 has
corresponding protrusions. The drainage features 28 on the second
sheet 26 can be dimples disposed such that the second sheet 26
first face 25 has depressions and the second sheet 26 second face
27 has corresponding protrusions. The first sheet 22 can be
disposed such that the second face 23 is parallel to the separator
sheet 30. Thus, the protrusions of the dimples 24 are disposed
toward the separator sheet 30. Similarly, the second sheet 26 can
be disposed such that the second face 27 is parallel to the
separator sheet 30. Therefore, the protrusions of the dimples 28
are disposed toward the separator sheet 30.
[0024] In one example, the first sheet 22 and/or the second sheet
26 can be secured to the separator sheet 30 in any suitable manner.
For example, the first sheet 22 can be glued to the separator
sheet, and the second sheet 26 is not secured to the separator
sheet 30. Alternatively, the first sheet 22 is not secured to the
separator sheet 30, and the second sheet 26 can be glued to the
separator sheet 30. In another example, the separator sheet 30 is
not secured to the first sheet 22 or the second sheet 26. In
accordance with one embodiment, the first sheet 22 and the second
sheet 26 can have holes (not shown) to allow water to flow from the
first faces 21, 25 of the sheets 22, 26 to the second faces 23, 27
of the sheets 22, 26 or vice versa.
[0025] The portion 20 has fabric 32 disposed around the first sheet
22, second sheet 26, and the separator sheet 30. The fabric 32 can
be a single sheet of fabric or more than one sheet of fabric. The
fabric 32 may be any suitable fabric that can allow water to flow
through the fabric 32 while restricting at least some soil and/or
other particulate from contacting the first sheet 22 and/or the
second sheet 26. For example, the fabric 32 may be a non-woven,
needle-punched polypropylene filter fabric or any other suitable
strip-drain type fabric. The fabric 32 may be secured to the first
sheet 22 or the second sheet 26 in any suitable location in any
suitable manner. For example, the fabric 32 can be glued to the
first sheet 22 and the second sheet 26 in various locations. The
fabric 32 is generally secured to the first sheet 22 and/or the
second sheet 26 somewhat loosely so that the first sheet 22 and the
second sheet 26 can bend easily in any desired direction.
[0026] The portion 20 provides a drain area with a large water
transport cross-section. Additionally, as illustrated in FIG. 3,
the portion 20 may be bent so that the portion 20 can be installed
around corners, such as foundation corners, without impeding water
flow. The separator sheet 30 prevents the fabric 32 or the dimples
24, 28 from impeding the flow path of water from traveling along
the portion 20, as shown in FIG. 3. Therefore, the portion 20
provides a drainage area that can be installed around inside or
outside corners without requiring additional steps to ensure water
flow. It will be understood that the drainage assembly 12 can have
a portion 20 of any suitable size. It will be further understood
that the drainage assembly 12 can be entirely comprised of a
portion 20. The portion 20 can be installed on a building or
building foundation in any desired manner.
[0027] Referring now to FIGS. 6 and 7, alternative embodiments of
the portion 20 having expansion features are illustrated. The first
sheet 22 has first and second side edges 70, 72 and first and
second top edges 74, 76. Additionally, the first sheet 22 has an
expansion feature 78. For purposes of describing and defining the
present invention, the term "expansion feature" shall be understood
as referring to any feature that allows a sheet to expand or
contract when the sheet is handled or rolled.
[0028] It will be understood that any suitable expansion feature 78
can be employed. For example, as illustrated in FIG. 6, a v-shaped
hinge 78 can be provided in the sheet 22. In another example, as
illustrated in FIG. 7 a perforation 78 can be provided. The
perforation 78 is generally provided in the sheet 22 such that the
assembly 12 can be assembled with the edges of the perforation
remaining in contact, and the perforation 78 can be disposed to
tear upon rolling of the assembly 12.
[0029] The expansion feature 78 can be provided on the sheet 22 in
any suitable manner. For example, the expansion feature 78 can be
disposed to run between the first and second sides 70, 72 of the
first sheet 22. Alternatively, the expansion feature 78 can be
disposed to run between the top and bottom edges 74, 76 of the
first sheet 78. Generally, the expansion feature 78 is disposed on
the first sheet 22 such that the assembly 12 can be rolled with the
first sheet 22 on the outside of the roll so that the expansion
feature 78 can expand to accommodate the second sheet 26. In
another example, the first sheet 22 and the second sheet 26 can be
provided with expansion features 78.
[0030] Referring now to FIGS. 8-12, additional alternative
embodiments of the portion 20 are illustrated. In this embodiment,
the portion 20 does not have a separator sheet 30. Instead, the
first face 21 of the first sheet 22 is parallel and adjacent to the
first face 25 of the second sheet 26. In one example, the first
face 21 of the first sheet 22 is in contact with the first face 25
of the second sheet 26. The first sheet 22 and the second sheet 26
have drainage features 24, 28. In one example, the drainage
features 24 on the first sheet can be dimples disposed such that
the first sheet 22 first face 23 has depressions and the first
sheet 22 second face 25 has corresponding protrusions. The drainage
features 28 on the second sheet 26 can be dimples disposed such
that the second sheet 26 first face 25 has depressions and the
second sheet 26 second face 27 has corresponding protrusions.
Therefore, the drainage features 24, 28 are disposed such that the
drainage features 24, 28 extend in opposite directions.
[0031] The first sheet 22 and the second sheet 26 can have openings
90 provided such that water can flow from the first face 21, 25 to
the second face 23, 27 of the first or second sheet 22, 26. The
openings 90 can be of any suitable shape. For example, the openings
90 can be slot shaped or circular. In one example, the first sheet
22 has a plurality of the openings 90 and second sheet 26 has a
plurality of the openings 90. More than one of the plurality of
openings 90 in the first sheet 22 can be aligned with an associated
opening in the second sheet 26 such that water can flow from the
first sheet 22 second face 23 to the second sheet 26 second face
27.
[0032] In one example, the openings 90 in the first sheet 22 can be
slot shaped, and the openings 90 in the second sheet 26 can be slot
shaped. The slot shaped openings 90 can be disposed on the sheets
22, 26 in any suitable manner. For example, referring to FIG. 10,
the slots 90 can be disposed such that the slots are normal to a
side edge 72 of the first sheet 22 and a side edge 84 of the second
sheet 26. Alternatively, referring to FIG. 11, the slots 90 can be
disposed such that the slots 90 are parallel to a side edge 72 of
the first sheet 22 and a side edge 84 of the second sheet 26. This
parallel or normal slot 90 configuration provides increased
tolerance to vertical or horizontal misalignment of the first sheet
22 with the second sheet 26, because the slots 90 can be somewhat
misaligned without impeding water flow between the second face 23
of the first sheet 22 and the second face 27 of the second sheet
26.
[0033] In another alternative, referring the FIG. 12, the slots 90
can be disposed such that the slots project diagonally across the
sheets 22, 26 in relation to a side edge 72 of the first sheet or a
side edge 84 of the second sheet 26. This diagonal slot 90
configuration provides increased to vertical and horizontal
misalignment of the first sheet 22 with the second sheet 26.
[0034] In one embodiment, as shown in FIG. 1, the portion 20 may be
disposed to provide drainage from the top 34 of a building footer
36 down the side 38 of the footer 36 to any desired depth. The
portion 20 may be used in conjunction with any suitable strip-drain
type fittings, such as strip-drain pipes, in order to direct water
flow to a desired location in the drainage system 10. The portion
20 may be bent around the corners of the footer 36 without impeding
water flow down the footer 36.
[0035] Referring now to FIGS. 1 and 8, in accordance with
embodiments of the present invention, the drainage assembly 12 may
further have a second portion 40. The second portion 40 and can
comprise a single sheet 44 having drainage features 46 at least
partially covered by fabric 32, as shown in FIGS. 4 and 5. In one
example, the second portion 40 is fully covered by fabric 32. The
second portion 40 very flexible because a single sheet 44 is used.
The drainage features 46 can be any suitable drainage features,
such as dimples as discussed herein. The fabric 32 may be provided
as a continuous sheet of fabric that extends from the portion 20.
Alternatively, the fabric 32 may be provided in as many pieces as
suitable. The fabric 32 may be secured to the second portion 40 at
any suitable location. The fabric 32 is generally very loosely
secured to the second portion 40 to allow the second portion 40 to
bend as needed. The second portion 40 may be a separate sheet or a
continuous sheet. Additionally, the portion 20 and the second
portion 40 may provided as separate sheets, a continuous sheet, or
some of the portions 20, 40, may be separate sheets while some are
continuous sheets.
[0036] The second portion 40 can be disposed to provide a drainage
path from the foundation wall 16 along the top 34 of the footer 36.
The fabric 32 can be glued or otherwise secured to the second
portion 40 proximate to location 48 and location 50 to form a
pocket in which portion 20 can be secured.
[0037] The second portion can be further provided on the foundation
wall 16 or over any waterproofing or drainage systems, such as the
board 18 as shown. The second portion 40 may be installed with the
drainage features 46, such as dimples, pointing toward the drainage
board 18 if it is present to provide collection of water along the
board 18. Alternatively, the second portion 40 can be installed
with the drainage features 44, such as dimples, pointing away from
the foundation wall 16 to maximize water collection. The second
portion 40 can be of any suitable dimensions and can be installed
to any desired height on a building.
[0038] The drainage assembly 12 having portions 20, 40 can provide
drainage from a foundation wall 16 down the footer 36. The drainage
assembly 12 can further provide a connection between the foundation
wall 16 to a lower level continuous drainage area (not shown) below
or beside the footer 36. The drainage assembly 12 does not require
the use of traditional gravel and tile drainage systems. The
drainage assembly 12 can be used alone or conjunction with other
waterproofing or drainage systems for buildings. The drainage
assembly 12 illustrated in FIGS. 1 and 8 can provide a lower water
transport area via portion 20 than traditional strip-drain type
assemblies because water transport is provided along the side of
the footer 36 in connection with a water collection area 40 above
the footer 36. Additionally, the water collection area on the
foundation wall 16 via portions 40 is flexible.
[0039] It will be understood that the drainage assembly 12 of the
present invention is not limited to having the portions or
dimensions illustrated. For example, the drainage assembly 12 can
entirely comprise a portion 20 that can be installed from the side
38 of a footer 36 all the way up the foundation wall 16.
Alternatively, the drainage assembly 12 can have a portion 20 that
can be installed partially up a foundation wall 16 with a portion
40 providing drainage further up a foundation wall 16.
[0040] It will be readily apparent to those skilled in the art that
various changes may be made without departing from the scope of the
invention, which is not to be considered limited to what is
described in the specification.
