[0001] This invention relates to a shower tray arrangement for disabled persons.
[0002] It is often difficult for disabled persons who are confined to a wheelchair or the
like to use a shower because the shower tray has an upstanding rim which makes it
difficult or impossible for a wheelchair to be manoeuvred into and out of the shower.
[0003] GB-A-2 244 428 describes a shower tray for disabled persons in which an aluminium
grill or duck board is supported above the water level by means of a frame which is
arranged solely around the periphery of the grill. This has the disadvantage that
the grill has to be capable of supporting the weight of a disabled person across the
entire area thereof while itself only being supported around the periphery. This requires
the grill to be very substantial and increases the cost of the grill and the complexity
thereof.
[0004] It is therefore an object of the present invention to provide a shower tray arrangement
which can more readily be used by disabled persons, such as those confined to a wheelchair,
and which overcomes the disadvantages of known shower trays.
[0005] According to the present invention there is provided a shower tray arrangement for
disabled persons and comprising a tray having a base, an upstanding side wall and
an outlet, and a surface supported above the base of the tray substantially coplanar
with an upper edge of the upstanding side wall of the tray at least over part of the
length thereof, wherein the surface is perforated and is supported above the base
of the tray by means of a plurality of protrusions extending downwardly from the underside
of the perforated surface to engage the base.
[0006] The tray may incorporate a rim provided in the region of the upper edge of the wall
and extending outwardly of the tray.
[0007] The base of the tray may be of variable thickness, the thickness decreasing progressively
towards the outlet.
[0008] The outlet may be positioned in the region of a corner of the tray or generally centrally
thereof. Alternatively, the outlet may be formed in the side wall of the tray, for
example as a slot.
[0009] A ramp may be positioned along one or more sides of the tray.
[0010] A plurality of discrete protrusions may be provided. The protrusions may be spaced
across the underside of the perforated surface. The protrusions may be substantially
columnar.
[0011] The perforated surface may be formed by a plurality of rib members. The rib members
may be arranged in groups positioned at angles relative to each other. The rib members
may be curvilinear, for example curved, orthogonal and/or diagonal relative to the
tray.
[0012] The perforated surface may be comprised of a plurality of tiles. The tiles may be
formed with the protrusions remote from the periphery thereof, in which case the protrusions
may be generally cylindrical, and/or the tiles may be provided with protrusions around
the periphery thereof, in which case the protrusions may be generally rectangular.
The rectangular protrusions may be spaced in a manner which permits engagement with
one or more interlocking members provided on an adjacent tile.
[0013] For a better understanding of the present invention and to show more clearly how
it may be carried into effect reference will now be made, by way of example, to the
accompanying drawings in which:
Figure 1 is a diagrammatic cross sectional view of part of one embodiment of a shower
tray arrangement according to the present invention;
Figure 2 is a diagrammatic plan view of the shower tray arrangement shown in Figure
1 to a different scale;
Figure 3 is a diagrammatic cross sectional view of a modification of the shower tray
arrangement shown in Figure 1;
Figure 4 is a diagrammatic cross sectional view, to a different scale, of part of
the shower tray arrangement of Figure 1 adapted for mounting on a surface;
Figure 5 is a top plan view of a tile for use in the shower tray arrangements of Figures
1 to 4; and
Figure 6 is a bottom plan view of the tile shown in Figure 5.
[0014] The shower tray arrangement shown in Figures 1 and 2 comprises a shallow tray 1 incorporating
a base 3, a peripheral upstanding side wall 5 and a rim 7 extending outwardly from
the region of the upper edge of the side wall 5. The tray 1 may be made of any suitable
material, such as cast aluminium or aluminium alloy, which may be provided with an
enamel or like coating.
[0015] The tray 1 is substantially square in the illustrated embodiment and may have internal
dimensions of about 900 mm by 900 mm. However, it should be noted that the tray may
be made with a range of dimensions and may be either square or rectangular, such as
1200 mm by 1200 mm, 1500 mm by 1500 mm, 900 mm by 1200 mm, 900 mm by 1500 mm, or 1200
mm by 1500 mm. The side wall 5 may have a height of about 20 mm and a thickness of
about 5 mm, the height being adapted to permit the tray to be recessed into floorboards
9 so as to be supported by floor joists 11. A tray of these dimensions can hold at
least about 10 litres of water which is adequate in practice even if the water should
flow away relatively slowly. The rim may have a width of about 35 mm and a thickness
of about 5 mm. A number of apertures 15 may be provided through the rim 7 to assist
in securing the tray to the surrounding floorboards.
[0016] The base 3 of the tray is of variable thickness, the thickness decreasing progressively
towards an outlet 13 so as to direct water received in the tray towards the outlet
which is positioned adjacent to a corner of the tray. For example, the tray may vary
in thickness between 10 mm and 5 mm. This permits the lower surface of the tray to
be substantially planar in order to facilitate installation.
[0017] In a further embodiment (not illustrated) the outlet may be formed as a slot in the
side wall 5 rather than in the base of the tray 1. This can assist where space beneath
the tray is limited.
[0018] Positioned within the tray 1 and supported by the base 3 is a plurality of tiles
17 which may be, for example, of plastics material. The upper surface of the tiles
17 is substantially level with the rim of the tray 1 at least along part of the length
of the side wall 5 so as to facilitate entry and exit by a person in a wheelchair.
[0019] In the shower tray arrangement shown in Figure 3, the outlet 13 is positioned substantially
centrally of the tray and the thickness of the base decreases progressively from the
edges thereof towards the outlet.
[0020] The shower tray arrangement of Figure 4 illustrates how the tray 1 can be positioned
on a solid surface, for example of concrete, instead of being recessed. In the embodiment
of Figure 4, a ramp 19, for example of suitable non-slip material, is positioned along
one or more sides of the tray to enable a person in a wheelchair to mount the ramp
and enter the shower tray arrangement. The ramp 19 comprises an inclined portion 21,
which is provided with an upright supporting leg 23 intermediate the ends thereof,
and a lateral portion 25 recessed below the uppermost point of the inclined portion
so as to fit beneath the rim 7 of the tray, the lateral portion being provided with
an upstanding supporting leg 27 at the free end thereof. Where the ramp 19 is to be
provided along adjacent sides of the tray 1, the adjoining ends of the ramp may be
mitred.
[0021] The tiles 17 are shown in more detail in Figures 5 and 6, although tiles may be used
having different configurations to that illustrated. The tiles 17 comprise a perforated
upper surface 29, in the present case the perforated upper surface being formed by
a plurality of intersecting orthogonal and diagonal rib members 31, and a number of
protrusions 33 and 35 extending down from beneath the upper surface to a substantially
common plane (where the protrusions engage the base of the tray) for supporting the
perforated surface 29 above the base 3 of the tray 1 so as to enable water to flow
more readily towards the outlet 13 of the tray. Protrusions 33 remote from the edges
of the tile may be cylindrical as illustrated, while protrusions 35 around the periphery
of the tile may be substantially rectangular as illustrated. Protrusions 35 are spaced
in a manner which permits engagement with interlocking members 37 which are provided
along one or two sides of the tiles in order to permit adjoining tiles to be interlocked.
In this way the individual tiles can be locked together to form a safe and continuous
perforated surface supported above the base of the tray 1 and which permits ready
entry and exit for a person in a wheelchair. Additionally, the tiles 17 can readily
be removed from the tray 1 to facilitate cleaning of the tiles and the tray.
[0022] The individual tiles may be substantially square, for example about 300 mm by 300
mm, the tiles having an overall thickness of about 15 mm, of which about 7.5 mm is
occupied by the perforated surface 29 and about 7.5 mm is occupied by the protrusions
33, 35.
