Field of the Invention
[0001] The invention relates to a frame for a storage system, for example an understairs
or under similar pitched spaces.
Background to the Invention
[0002] In a typical home, the space under the stairs typically occupies 1.11 square metres
(12 square feet) of the overall footprint of a house. Typically this space is rarely
utilised effectively. Similarly, attic space and particularly in the space under the
roof pitch storage space is rarely utilised effectively. Drawer units or other closet
structures are often fitted under the stairs of houses to utilise this space as understairs
storage.
[0003] As shown in Figure 1 stairs generally have a range of pitches β. Typically stairs
have a range of pitches β which may be from about 39° to about 50°. Accordingly to
install an under stairs storage unit it is necessary to match the angle of the under
stairs storage unit to the pitch of stairs. While stairs in houses are typically of
similar heights, H, (approximately 2440 mm), the space available under the stairs
will be determined in part by the pitch of the stairs. As the space under a stairs
is substantially triangular in shape the space available will be governed by the relationship
between the height H, the pitch β and the length, L. That is stairs with a greater
pitch will have a smaller footprint while stairs with a lesser pitch will have a greater
footprint. The footprint of the stairs can also be influenced by features of a house
such as the presence or absence of understairs toilet facilities which reduce the
available space for understairs storage. The footprint available can be generally
defined as either normal wherein the length, L, is less than 1000mm or larger than
normal wherein the length, L, is greater than 1000mm. Accordingly to install an under
stairs storage unit it is necessary for the under stairs storage unit to match the
footprint of the stairs to utilise the space there as effectively as possible. Stairs
may be orientated from left to right or from right to left. Accordingly to install
under stairs storage units it is necessary to match the orientation of the stairs.
As can be appreciated the range of parameters to consider when providing under stairs
storage units means that these units are typically of bespoke manufacture.
[0004] Typically a plurality of drawers are installed under the stairs to optimise the space
utilisation. However, while drawers may be generic, the installation of these drawers
and the installation and framing system are bespoke, tailored to match the individual
requirements of individual stairs or pitched space. Bespoke manufacture is required
as houses have varying pitches of stairs and the angle of the pitch of the stairs
can vary from 35° to 50°. Bespoke manufacture is required as the orientation of stair
rise can vary from house to house, with different configurations of drawer units being
required for stairs orientated to rise from left to right and stairs orientated to
rise from right to left. Bespoke manufacturing is required as the footprint under
stairs can vary. Bespoke manufacture is both time consuming and expensive. Bespoke
manufacture, by its nature of once off manufacturing, is prone to waste which may
be detrimental to the environment in addition to increasing the carbon footprint of
each bespoke unit. Kits are available for such storage solutions, but separate kits
are provided for each pitch and for each stair orientation. The requirement for the
provision of separate kits resulting in increased manufacturing costs, component cost,
delivery, storage costs and often the need for a qualified person to install the storage
solution. It is therefore an aim of the present invention to provide a universal kit
which reduces the component count for a storage solution such as that described herein.
Summary of the Invention
[0005] As described herein with reference to the appended claims, there is provided a frame
for an understairs storage system, the system having a plurality of substantially
triangular gussets, each gusset having a gusset pitch (α), comprising:
a first support member and a second support member, each of the first and second support
members having a plurality of preconfigured engagement points, the preconfigured engagement
points of the first support member pairing with the plurality of engagement points
of the second support member to provide a plurality of pairs of engagement points;
each pair of engagement points configured to cooperably engage a gusset of the plurality
of gussets at a convergent point of the first and second support members to orientate
the second support member at a preselected angle, x, to the first support member,
said preselected angle corresponding to the gusset pitch. The frame provides for a
single solution for a plurality of pitch angles thus reducing manufacturing costs,
component cost, delivery, storage costs, and simplifying installation. This further
reduces environmental waste, and the associated carbon footprint associated with manufacturing.
[0006] The first support member may have a longitudinal length, wherein the first plurality
of pre-configured engagement points may be positioned at a distal end of the longitudinal
length at a distance from a proximate end of the first support member the distance
in millimetres being 32α - Y, α being the gusset pitch and Y being a constant.
[0007] The positioning of the plurality of pre-configured engagement points on the first
support member according to the equation 32α - Y allows the first support member to
be attached to gussets with varying pitches in such a manner as to allow a single
frame to be fitted under stairs of different pitches. Advantageously the positioning
of the preconfigured engagement points allow a single frame to be fitted under stairs
of right to left or left to right orientation. Advantageously the positioning of the
pre-configured engagement points according to the equation 32α - Y allows the first
support member to be configured to fit under stairs of different footprints. Advantageously
the positioning of the pre-configured engagement points provides a single frame which
can be configured to fit under numerous configurations of stairs.
[0008] The footprint available under the stairs may be of normal or greater than normal
size. A normal size footprint is one which the horizontal length, L, is less than
1000 mm, for example 952mm. A greater than normal footprint is one in which the horizontal
length, L, is greater than 1000 mm, for example 1102 mm.
[0009] The frame of the present invention the frame may be configured to fit under stairs
with a normal size footprint wherein the horizontal length, L, is less than 1000 mm,
wherein Y may have a value of from about 390 to about 400. Y having a value of from
about 390 to about 400 allows the frame to be correctly positioned under the stairs
having a pitch from 39° to 50°. A value of Y below 400 may position the gusset on
the first support member too low to fit neatly under stairs. A value of Y above 390
may position the gusset too high on the first support member and prevent the frame
from fitting under stairs. Preferably Y has a value of 395 which will allow the frame
to be positioned neatly under stairs.
[0010] Alternatively the frame of the present invention may be fitted under stairs which
have a greater than normal footprint wherein the horizontal length, L, is greater
than 1000 mm. In this case Y may have a value of from about 260 to about 270. Y having
a value of from about 260 to about 270 allows the frame to be positioned correctly
under stairs of greater than normal footprint wherein the horizontal length, L, is
greater than 1000 mm. A value of Y below 270 may position the gusset on the first
support member too low to fit neatly under stairs. A value of Y above 260 may position
the gusset too high on the support member and prevent the frame from fitting under
within the footprint of the stairs. When the frame is configured to be positioned
under stairs of greater than normal footprint wherein the horizontal length, L, is
greater than 1000 mm, preferably Y has a value of 267 which will allow the frame to
be positioned in the correct orientation to fit neatly under stairs.
[0011] The second support member may have a longitudinal length and wherein the second plurality
of pre-configured engagement points may be positioned at a distal end of the longitudinal
length at a distance from a proximate end of the second support member the distance
in millimetres being 10.66α + Z, α being the pre-selected angle and Z being a constant.
The positioning of the plurality of pre-configured engagement points according to
the equation 10.66α + Z may allow the second support member to be attached to gussets
with varying pitches in such a manner as to allow a single frame to be fitted under
stairs of different pitches. Advantageously the positioning the preconfigured engagement
points allow the frame to be fitted under stairs of right to left and left to right
orientation. Advantageously the positioning of the pre-configured engagement points
allow the frame to configured to be fitted under stairs of different footprints. Advantageously
the positioning of the pre-configured engagement points provides a single frame which
can be configured to fit under numerous configurations of stairs.
[0012] The frame may be configured to fit under stairs with a normal size footprint wherein
the horizontal length, L, is less than 1000 mm, wherein the frame of the present invention
Z may have a value of from about 210 to about 220. Z having a value of from about
210 to about 220 allows the frame to be correctly positioned under the stairs. A value
of Z below 210 may prevent the second support member from fully extending the length
of the stairs. A value of Z above 220 may make the second support member too long
and prevent the second support member form fitting under a stairs. Preferably Z has
a value of 216 which will allow the frame to be positioned neatly under stairs.
[0013] The frame may comprise a third support member comprising a third plurality of pre-configured
engagement points wherein the third support member and a fourth support member may
be orientated at the pre-configured angle and wherein the fourth support member may
be identical to the second support member. The third support member may provide additional
support to the frame.
[0014] The third support member may have a longitudinal length and wherein the third plurality
of pre-configured engagement points may be positioned at a distal end of the longitudinal
length at a distance from a proximate end of the third support member the distance
in millimetres being 16α - A, α being the pre-selected angle and A being a constant.
The positioning of the plurality of engagement points on the third support member
according to the equation 16α - A may allow the third support member to be attached
to gussets of varying pitches in such a manner as to allow a single frame to be fitted
under stairs of different pitches. Advantageously the positioning of the preconfigured
engagement points allow a single frame to be fitted under stairs of right to left
or left to right orientation. Advantageously the positioning of the pre-configured
engagement points according to the equation 16α - A allows the first support member
to be configured to fit under stairs of different footprints. Advantageously the positioning
of the pre-configured engagement points provides a single frame which can be configured
to fit under numerous configurations of stairs
[0015] The frame of the present invention the frame may be configured to fit under stairs
with a normal size footprint wherein the horizontal length, L, is less than 1000 mm,
wherein A may have a value of from about 140 to about 150. A having a value of from
about 140 to about 150 allows the frame to be correctly positioned under the stairs.
A value of A below 150 may position the gusset on the third support member too low
to fit neatly under stairs. A value of A above 140 may position the gusset too high
on the third support member and prevent the frame from fitting under stairs. Preferably
A has a value of 145.5 which will allow the frame to be positioned neatly under stairs.

[0016] Embodiments of the invention will be described, by way of example only, with reference
to the accompanying drawings in which:
Figure 1 is a side profile of a sample understairs space for fitting the frame in accordance
with present invention.
Figure 2 depicts a side profile view of an embodiment of the frame installed in the understairs
space of figure 1.
Figure 3 provides exemplary sectional views of the first to fourth support members in accordance
with an embodiment of the invention;
Figure 4 shows an embodiment of the frame of the present invention arranged to support drawer
units.
Detailed Description of the Drawings
[0017] An embodiment of the frame of the present invention is shown in figure 2. In this
embodiment the frame is formed by a first support member 101 and a second support
member 102. The first support member 101 and second support member 102 engage a gusset
100. The gusset provides both a technical guide and also a pleasing cosmetic finish.
As shown herein typically a gusset 100 is substantially triangular in shape. However
the gusset 100 may be right trapezoid in shape 300, but other configurations are equally
applicable. The embodiment in figure 2 shows the first support member 101 substantially
upright. The second support member 102 is positioned at an angle relative to the first
support member. The gusset is positioned between the first support member and the
second support member at their convergent points.
[0018] The gusset 100 has a gusset pitch α. The gusset pitch α is defined as the angle formed
by the sides 100a and 100b of the gusset 100 which is shown as triangular. Alternatively
a right trapezoid gusset 300 has a gusset pitch α which is defined as the angle formed
by sides 300a and 300b.
[0019] A gusset 100 is selected which has a gusset pitch which corresponds to the pitch
the stairs β under which the under stairs storage system is to be fitted. As shown
in figure 2 the pitch of the stairs β is used to select the gusset pitch α with the
gusset pitch selected to match the pitch of the stairs β as closely as possible to
allow the frame to fit closely under the stairs. The gusset pitch α corresponding
to the pitch of the stairs β allows the frame to be correctly orientated to fit neatly
under the stairs. A gusset pitch α which is greater than the pitch of the stairs β
may lead to the frame will not fitting under the stairs as the angle of the second
support member may intersect with the stairs itself. A gusset pitch α smaller than
the pitch of the stairs β may lead to the frame having a poor aesthetic appearance.
Typically the gusset pitch α may be selected from any angle from about 39° to about
50°, for example the gusset pitch α may be 39°, 40°, 41°, 42°, 43°, 44°, 45°, 46°,
47°, 48°, 49°, or 50°, or fractions thereof.
[0020] An understairs installation is shown in Figure 2. As outlined above the frame comprises
the first support member 101. The first support member 101 provides stability and
support to the frame. The first support member 101 has a longitudinal length. The
longitudinal length of the first support member 101 is defined as the distance from
a distal end 106 to a proximal end 107 of the first support member. The longitudinal
length of the first support member 101 is selected to match the footprint of the stairs.
As outlined above not all stairs will have the same footprint. The first support member
101 engages the gusset 100. The means of engagement is not shown but may be mechanical
or chemical attachment means such as screws, nails, adhesives, or any other suitable
means.
[0021] . The first support member 101 is shown as attached to a gusset 100 at a region close
to the distal end 106 of the longitudinal length of the first support member 101.
The positioning of the gusset 100 on the first support member 101 is determined by
a plurality of pre-configured engagement points 301 on the first support member 101
as shown in Figure 3. These preconfigured engagement points 301 are positioned to
engage with a plurality of gussets, thus allowing a single first support member 101
to engage with gussets of different angles. This allows for a single first support
member 101 to be manufactured wherein the single first support member is capable of
fitting under stairs of differing stair pitches β. As such the first support member
removes the need for bespoke manufacture of supports to fit under individual stairs.
[0022] The frame also comprises the second support member 102, shown positioned at an angle
in figure 2. The second support member 102 provides further stability and support
to the frame. The second support member 102 has a longitudinal length. The longitudinal
length is defined as the distance from a distal end 108 to a proximal end 109 of the
second support member. The second support member 102 is shown as attached to the gusset
100 at a region close to the distal end 108 of the longitudinal length of the second
support member 102. The positioning of the gusset on the second support member 102
is determined by a plurality of pre-configured engagement points 302 on the second
support member 102 are shown in Figure 3. These preconfigured engagement points 302
are positioned to engage with a plurality of gussets, thus allowing a second support
member 102 to engage with gussets of different angles. This allows for a second support
member 102 to be manufactured wherein the second support member 102 which is capable
of fitting under stairs of differing stair pitches β. As such the second support member
102 removes the need for bespoke manufacture of supports to fit under individual stairs.
[0023] The frame comprises an optional third support member 103 as shown in Figure 2. The
third support member 103 provides further stability and support to the frame. The
third support member 103 has a longitudinal length. The longitudinal length of the
third support member is defined as the distance from a distal end 110 to a proximal
end 111 of the third support member. The third support member is shown as attached
to a gusset 114 at a region close to the distal end 110 of the longitudinal length
of the third support member. The gusset 114 is identical to the gusset 100. The gusset
114 has the same gusset pitch α as gusset 100. The positioning of the gusset 114 on
the third support member 103 is determined by a plurality of pre-configured engagement
points 303 on the third support member 103 as shown in Figure 3. These preconfigured
engagement points 303 are positioned to engage with a plurality of gussets, thus allowing
a third support member 103 to engage with gussets of different angles. This allows
for a third support member 103 of the invention to be manufactured wherein the third
support member is capable of fitting under stairs of differing stair pitches. As such
the third support member 103 removes the need for bespoke manufacture of supports
to fit under individual stairs.
[0024] The frame also includes an optional fourth support member 104, shown positioned at
an angle in figure 2. The fourth support member 104 provides stability and support
to the frame. The fourth member 104 is identical to the second member 102. The fourth
support member 104 has a longitudinal length. The longitudinal length is defined as
the distance from a distal end 112 to a proximal end 113 of the fourth support member
104. The fourth support member 104 is shown as attached to the gusset 114 at a region
close to the distal end 110 of the longitudinal length of the fourth support member
104. The positioning of the gusset 114 on the fourth support member 104 is determined
by a plurality of pre-configured engagement points 304 on the fourth support member
104 as shown in Figure 3. These preconfigured engagement points 304 are positioned
to engage with a plurality of gussets, thus allowing the fourth support member 104
to engage with gussets of different angles. This allows for a fourth support member
104 to be manufactured wherein the fourth support member 104 is capable of fitting
under stairs of differing stair pitches β. As such the fourth support member 104 removes
the need for bespoke manufacture of supports to fit under individual stairs.
[0025] The third and fourth support member above are described as optional. Additional support
members may be incorporated depending on the under stairs requirement. These additional
support members allow for subdivision of the under stairs cavity.
[0026] To provide flexibility to allow a single first support member 101 and a single second
support member 102 to form a frame which may be positioned under stairs with different
pitches β, the position of the engagement points 301, 302 are preconfigured during
manufacture. As outlined above, the first support member 101 and the second support
member 102, each have a plurality of preconfigured engagement points 301, 302 as shown
in Figure 3. The plurality of preconfigured engagement points 301 of the first support
member 101 pair with the plurality of engagement points 302 of the second support
member 102 to provide a plurality of pairs of engagement points. These pairs of engagement
points co-operably engage a gusset, wherein the gusset has a gusset pitch α, the gusset
pitch α chosen to match the pitch of the stairs β as shown in Figure 2 and described
above.
[0027] The engagement points 301, 302, 303, 304, are shown in Figure 3 as holes but any
other means of preconfiguring the engagement points is also considered. For example
the engagement points may be through holes, blind holes, indents or raised portions,
markings made by for example by punches or printers, or any other suitable means of
preconfiguring the engagement points during manufacture.
[0028] To provide the flexibility outlined above the position of the engagement points 301,
302, 303, 304 are preconfigured during manufacture.
[0029] The positioning of the plurality of engagement points 301 of the first support member
101 may be determined by the distance in millimetres from the proximal end 107 defined
by:

β is 40°. The gusset will be chosen to have a gusset pitch α to match the pitch of
the stairs β so a gusset with a gusset pitch of 40° will be chosen from a plurality
of gussets. The position of the preconfigured engagement point 301 on the first support
member 101 will be calculated as 32(40) - Y. Where Y is 395 the preconfigured engagement
point 301 will be positioned at a distance from the proximal end 107 of the first
support member 101 of 885mm, which is 32(40) - 395. This embodiment may be suitable

on the first support member will be calculated as 32(40) - Y. Where Y is 267 the preconfigured
engagement point will be positioned at a distance from the proximal end of the first
support member of 1013mm, which is 32(40) - 267. This embodiment may be suitable for

engagement points 303, 304 are determined by the gusset pitch α, the preconfigured
engagement points form pairs of engagement points. Each pair of engagement points
is suitable for cooperably engaging a gusset with a specific gusset pitch α. Advantageously
the third support member 103 and the fourth support member 104 are manufactured with
a plurality of engagement points which form pairs of engagement points allowing a
single third support member and a single fourth support member to be manufactured
and be suitable for fitting under stairs without requiring bespoke manufacture of
a third support member and a fourth support member to fit under stairs with different
pitches β.
[0043] The frame of the invention may also comprise a fifth support member 105. The fifth
support member 105 may provide additional stability and support to the frame. As shown
in figure 2 the fifth support member may be positioned to engage the proximal end
107 of the first support member 101. The fifth support member 105 may be positioned
to engage the proximal end 111 of the third support member 103.
[0044] The frame as shown in Figure 4 is configured to provide support to drawers which
may be used as storage under a stairs. Gussets 100, 114 are chosen to match the stair
pitch. The frame is formed by a first support member 101 and a second support member
102. Additional support is provided to the frame by a third support member 103, a
fourth support member 104, and a fifth support member 105.
[0045] The under stairs storage in Figure 4 is shown with additional support members and
struts which may be configured to receive storage units, such as drawers or any other
suitable storage unit, of different dimensions. For example in Figure 4, a portion
of the first support member 101, a portion of the third support member 103, a portion
of the fifth support member 105 and a first strut 402 are configured to form an opening
in the frame suitable for supporting storage units. The storage units may be drawers,
boxes, crates, or any other means suitable for providing storage. The storage units
may be placed on supports, such as rails, which are configured to allow a user to
easily slide the storage unit from the opening and provides easy access to the storage
unit.
[0046] While one strut 402 is shown in Figure 4 there may be a plurality of struts provided.
As the skilled person would appreciate there are numerous configurations of the plurality
of struts which may be provided to form openings suitable for supporting storage units.
The openings may be substantially square in shape. The openings may be substantially
rectangular in shape. The openings may be substantially triangular in shape. The openings
may be any shape required for supporting storage units. The storage units may be any
shape such as square, rectangular, triangular or any other shape.
[0047] The frames shown in Figures 2 and 4 are shown in an arrangement suitable for providing
under stairs storage under a stairs which are rising from right to left. Advantageously
all embodiments of the present invention are suitable for providing under stairs storage
under a stairs which is rising from left to right.
