[0001] This invention relates to a bath screen.
[0002] A bath screen may be used in association with a bath which is provided with a shower
attachment, with the object of preventing splashed water from the bath or shower from
reaching the floor beyond the bath. Typically a bath screen extends approximately
to head height and to about 1/3 the length of the bath. In order not to hinder access
to the bath and cleaning of the end part of the bath at which the screen is provided,
screens are known which comprise a number of panels which are pivotally connected
to one another so as to be able to be folded in zigzag fashion to occupy a small space.
If the screen extends from the wall, when folded the panels overlie one another substantially
parallel to the wall.
[0003] Such multiple panel folding bath screens as known hitherto have disadvantages. They
tend to leak, due to the large number of parts involved and the inevitable gaps which
exist between them, and this is an increasing problem especially with the wide spread
use of pump-fed "power showers" in which water is discharged from a shower head with
considerable force. Further, when such screens are deployed for use they rarely stay
in the intended position, tending to rest in a shallow zigzag shape along the rim
of the bath rather than extending straight therealong. When not in use, they tend
to unfold themselves from the fully folded condition. Aesthetically, the large number
of parts involved in previously known screens has given them a "cluttered" appearance,
with the frames relatively thick compared with the width of the glass or transparent
plastic panels held thereby. This also makes them difficult to clean.
[0004] It is broadly the object of the present invention to address one or more of these
disadvantages of known screens. Other features and advantages of screens in accordance
with the present invention are referred to hereafter.
[0005] It is to be appreciated that, although we refer herein to a bath screen and describe
the use of a screen in accordance with the invention in relation to a bath, the screen
is in practice useable in other situations, whether or not similar or analogous requirements
exist. Accordingly a screen constructed as defined herein is to be regarded as within
the scope of the invention whatever its intended use may be.
[0006] According to one aspect of the present invention, we provide a bath screen comprising
a plurality of panels and means pivotally connecting said panels to one another for
folding in zigzag fashion and deployment in alignment with one another, wherein said
means pivotally connecting the panels is provided with detent means operable for holding
said panels in aligned deployment.
[0007] Preferably the connecting means between each adjacent pair of said panels comprises
respective mounting portions connected to said panels along adjacent edges thereof
and hinge means and seal means operative therebetween.
[0008] Preferably both said hinge means and seal means are afforded by a "living hinge"
element of flexible material joining the mounting portions to one another.
[0009] The mounting portions preferably are extrusions of a plastics material and preferably
the connecting means is a coextrusion of a first plastics material which constitutes
the mounting portions and a second material which constitutes the hinge element.
[0010] It will be appreciated that certain types of plastics material are highly flexible
and able, when utilised as living hinges, to withstand a large number of cycles of
hinging without suffering damage. Preferably such a material is used for the hinge
element; by way of example, the hinge element may be of "Hytrel" (trade mark).
[0011] Preferably the detent means comprises co-operative formations provided on the two
mounting portions of each connecting means, said formations being engageable with
one another when the connected panels are in alignment with one another.
[0012] The formations may comprise, respectively, undercut recess means and projection means
able to engage the recess means and resiliently deform while entering and leaving
the recess means. Conveniently the projection means may comprise a projecting limb
having an enlarged head which is able to deflect by resilient deformation of the limb
as it passes a lip at the entrance to a recess. There may be two spaced generally
parallel such limbs, with respective heads cooperable with opposed lips at the entrance
to a recess.
[0013] For fixing the screen to a vertical surface adjacent the bath, a free end of an end
one of the panels of the screen may be provided with a fixing means which comprises
a mounting portion and living hinge element as for one of the connecting means, but
having, instead of the other mounting portion, a fixing portion adapted to be connected
to the fixing surface.
[0014] Detent means may be operable between the mounting portion and the fixing portion
of the fixing means, as between the mounting portions of a connecting means between
adjacent panels.
[0015] One or more of the living hinge elements provided in the screen may be extruded in
the configuration it adopts when the screen is folded, so that the screen tends to
stay in the folded condition naturally. When deployed, the detent means resists the
natural tendency for it to return to the folded condition.
[0016] A lower edge of the screen may carry a seal element engageable with the rim of a
bath with which the screen is to be used. Such a seal element may comprise an extrusion
of a flexible material, connected along the lower edge of the panels at a number of
spaced positions so that folding of the screen is accommodated.
[0017] In accordance with another aspect of the invention, a bath screen comprising a plurality
of panels and means pivotally connecting the panels to one another for folding in
zigzag fashion and deployment in alignment with one another, is provided along its
lower edge with a seal element engageable with the rim of a bath with which the screen
is to be used, the seal element being offset outwardly from the centre line of the
screen panels, when deployed, with a gap therebetween sufficient to prevent capillary
transmission of water outwardly of the screen between the seal element and panels.
[0018] By "outwardly" we mean to the side of the screen panels remote from the interior
of the bath.
[0019] The invention will now be described by way of example with reference to the accompanying
drawings, of which:-
Figure 1 is a diagrammatic side elevation of an embodiment of bath screen in accordance
with the invention;
Figure 2 is a horizontal section through the screen;
Figure 3 is a further section but showing the screen in the folded condition and in
relation to a bath;
Figures 4 and 5 are vertical sections through part of the screen, illustrating a seal
element at the lower edge thereof.
Figures 6 and 7 are horizontal sections through a modified embodiment of the bath
screen.
[0020] Referring firstly to Figures 1 and 2 of the drawings, a bath screen comprises three
panels indicated generally at 10, 11, 12. The panels 10 and 11 are connected to one
another along adjacent vertically extending edges by a connecting means indicated
generally at 13, while the panels 11 and 12 are similarly connected to one another
by a connecting means 14. The connecting means 13, 14 are the same as one another
in section, but are oppositely oriented to one another to permit the screen to fold
in zigzag fashion as shown in Figure 3. The panel 10 is fixed, in use, to a vertical
surface, e.g. a wall surface, adjacent the head of a bath by a fixing means indicated
generally at 15.
[0021] Each of the panels 10, 11, 12 comprises a pane of transparent or translucent sheet
material, e.g. toughened glass or a suitably strong plastics material. The connecting
means 13 which joins such panes 16, 17 in the panels 10, 11 comprises two mounting
portions 18, 19 which are extrusions of a material such as PVC. The mounting portion
18 comprises a base 20 affording a recess 21 in which the extreme edge of the pane
16 is received, and walls 22 which extend away from the base 20 and converge to hold
the pane 16 between them at a small distance from the base. Similarly the mounting
portion 19 comprises a base 23 affording a recess 24 and walls 25 extending therefrom
to grip the pane 17 therebetween at a distance from its edge. The mounting portions
18, 19 are joined to one another by a "living hinge" element 26 of flexible material
extending between the base parts 20, 23 of the mounting portions. The living hinge
element 26 is co-extruded with the mounting portions 19, 18 so that it is firmly bonded
thereto, and is, for example, of a material such as "Hytrel" (trade mark) which has
the necessary flexibility and permits a large number of cycles of pivoting between
the mounting portions without failure. It will also be appreciated that it provides
an effective seal between the mounting portions, preventing water from passing from
one side to the other of the screen therebetween when in use.
[0022] Detent means are provided for holding the panels 10, 11 in alignment with one another
when the bath screen is deployed. The base 20 of the mounting portion 18 is provided
with two spaced projecting generally parallel limbs 27 which at their free ends have
enlarged heads with opposite outwardly directed nose portions 28. The base 23 of the
mounting portion 19 is provided, adjacent its recess 24, with an undercut recess 29
which at its entrance has opposed inwardly facing lips 30. The dimensions are such
that the projections 27 are able to enter the recess 29, deforming slightly towards
one another as the nose portions at their ends 28 pass the lips 30 as the panels of
the screen approach their aligned fully deployed condition. The effect is that the
screen is held in such condition until sufficient force is applied thereto to disengage
the projections 27 from the recess 29 when the screen is to be folded. Preferably
the hinge 26 is moulded in the condition in which it is shown in Figure 3, i.e. with
the screen folded so that when set in its folded condition the screen will tend to
stay there.
[0023] As above referred to, the connecting means 14 is identical to the connecting means
13, but is assembled to the panes forming the screen in the opposite orientation so
that the screen folds in zigzag fashion as shown in Figure 3.
[0024] For fixing the screen to a surface such as a wall surface at the head of a bath,
the fixing means 15 comprises a mounting portion 32 whose configuration is analogous
to that of the mounting portion 19 of the connecting means 13, and which holds the
pane 16 of the panel 10. The mounting portion 32 is of a slightly elongated shape
in cross-section compared with the mounting portion 18, so that the pane 16 is spaced
somewhat from a base part 33 of the fixing means. The fixing means further comprises
a fixing portion 34 which is flat for fixing to a wall surface by fasteners 35 as
seen in Figures 1 and 2. The base 33 of the mounting portion 32 and the fixing portion
34 are joined by a co-extruded living hinge element 36. The fixing portion 34 and
mounting portion 32 of the fixing means have cooperating detent means, constituted
by headed projections 37 on the fixing portion 34 engageable, with some resilient
deflection, in an undercut recess 38 defined by a pair of projections 39 from the
base 33, the projections 39 having opposed inwardly facing lips at their free ends.
[0025] Thus the cooperating detent means in the fixing means 15 ensures the panel 10 is
normally held in a deployed orientation at right angles to the wall surface to which
the fixing means 15 is secured, but if required the panel 10 may be pivoted to lie
parallel to such wall surface.
[0026] Figures 4 and 5 of the drawings show in detail the configuration of a seal 40 provided
along the lower edge of the bath screen, for engaging the rim indicated at 41 of the
bath when the screen is deployed. A flexible hollow rubber extrusion 42 having a T-section
rib 43 on its upper surface is held by respective lugs 45 on lengths 44 of a rigid
plastics extrusion which are held at the bottom edges of the glass panes of the panels
10 to 12. The extrusion 44 affords a recess in which the panes are received, and in
this recess there are small deformable lugs 46 which grip the glass but which allow
the bottom seal assembly to be adjusted vertically relative to the pane. This ability
to adjust the seal is necessary to ensure that the extrusion 42 satisfactorily engages
the bath rim: in practice the wall to which the screen is fixed is unlikely to be
exactly perpendicular to the rim of the bath.
[0027] Figure 5 is a vertical section through the middle of one of the connecting means
13, 14, with details of the connecting means omitted for clarity. Extrusion 44, which
has of course ended at the connecting means, is also omitted. It will be noted that
a gap 47 is defined between the extrusion 42 and the pane 16 (or 17, etc, as the case
may be). Vertically between the panels forming the screen the "living hinges" incorporated
in the connecting means provide a permanent barrier to the passage of water. However,
because the hinges are offset from the centre line of the screen the sealing extrusion
42 must move relative to the vertical extrusions while the screen is being folded,
and hence the seal cannot be rigidly fixed to the bottom of these extrusions, giving
rise to a potential gap for leakage of water. It has been found that water will tend
to be drawn through a small gap by capillary action, whilst the provision of a larger
gap as 47 prevents this effect from taking place. It will also be noted that the seal
extrusion 42 is offset from the centre line of the screen, away from the "wet" side
thereof. This substantially reduces leakage.
[0028] Referring now to figures 6 and 7 of the drawings, these show, in horizontal sections
analogous to those appearing in figures 2 and 3, a modified embodiment of bath screen
in accordance with the invention. The following description will be confined to the
differences from the embodiment above described. In this embodiment, the connecting
means as 13 is different in that, instead of the two spaced generally parallel limbs
27 with oppositely outwardly directed nose portions 28 adjacent their three ends,
there is only a single limb 127 with an enlarged head 128. The limb 127 is able to
deform as the head 128 passes lip 30 at the entrance to recess 29, to provide a detent
action for holding the adjacent panels of the screen in their aligned fully deployed
condition. This arrangement provides a somewhat "easier" detent action than when there
are two such limbs.
[0029] The fixing means indicated generally at 115 is also different from the fixing means
15 described above. It comprises a panel-mounting portion 132 which holds the edge
of the first pane of the screen, and a fixing portion 134 which is generally T shaped
in cross-section, comprising a part 134
a for lying against a wall surface and a part 134
b extending at right angles therefrom. The part 134
b and mounting portion 132 are joined by a co-extruded living hinge element 136. There
is no co-operating detent means by which the first panel of the screen can be held
in a deployed orientation at right angles to the wall surface to which the fixing
means 115 is secured: maintenance of the panel in such position is dependant on the
resilience of the material forming the living hinge 136, returning to its as-extruded
configuration.
[0030] For concealing fasteners used to secure the fixing portion 134 to a wall surface,
the outer edges of the base part 134
a thereof are provided with relatively thin cover parts 150 joined to the part 134
a by thin hinge sections. The free edges of the cover parts 150 are provided with retaining
formations 151 engagable with lugs 152behind the end of the part 134
b where the hinge extrusion 136 is attached. Thus with the cover parts in the position
wherein they are as shown in figure 6 fasteners can be passed through the part 134
a to secure it to a wall surface, after which the cover parts can be moved to the position
shown in figure 7 and the formations 151, 152 engaged to hold the cover parts in such
position, so that the fasteners are concealed.
[0031] Thus the invention provides a bath screen which is simple in construction, utilising
a minimal number of separate parts. At the same time, it achieves a high degree of
effective sealing against water leakage when in use, while maintaining a "clean" and
attractive appearance.
