SHOWER CURTAIN GUARD DEVICE
Abstract
A shower curtain guard for use particularly in connection with
shower enclosures above conventional bath tubs, comprises a
vertical bar or rail, attached by a double adhesive medium, to the
wall at one or both ends of the tub. The rail is bent inwardly
above the tub to hold the lower end of the curtain within the tub
while affording a wider shower compartment above the tub. A spongy
plastic seal prevents escape of water between the tub and the lower
end of the bar or rail. Interlocking fibre patches on the curtain
and on the rail which are separable secure the curtain so as to
prevent water passing outside the compartment.

Description
BACKGROUND AND PRIOR ART
The use of shower curtains in connection with bath tubs to convert
the space above the tub into a shower compartment is almost
universal. However, many of the prior art curtain arrangements
permit water to escape outside of the tub, or they hang too deeply
into the tub, so as not to be pressed outside of it by the spraying
water. This causes excessive soaking and damages the curtain. Other
arrangements involve complicated fastenings. Most users desire a
simple, readily detachable holding means which secures the curtain
firmly and adequately but can be released easily. A guard is needed
that can be installed in the bathroom without drilling into tiled
walls or resorting to other difficult operations.
The shower curtain obviously should seal at least one corner of the
compartment above the tub against leakage, i.e., at least the
shower end. It should extend to the ceiling above the tub, or at
least to a point high enough that the shower water will not spray
outside the compartment, and it should deflect all water running
down the inside of the curtain into the tub.
The present invention is designed to meet all the foregoing
requirements and also to meet other requirements or preference
features not specifically mentioned above.

DESCRIPTION OF PREFERRED EMBODIMENT
FIG. 1 shows a part of a wall 10 at the end of a conventional bath
tub 11. In some cases, it is only necessary to secure a shower
curtain (shown diagrammatically in section at 20) at one end, i.e.,
to one wall at one end of the tub. In other cases, it may be
desirable or necessary to secure both ends of the curtain, i.e., at
both ends of the tub one end, of course, being detachable to
provide access to the tub enclosure. For purpose of describing the
present invention, means for fastening at one end will be
described, it being understood that the structure of FIG. 1, or
part of it, may be duplicated at the other end of the tub, which is
not shown in the drawings.
The principal physical element of the invention is an upstanding
bar or rail 13 which, in cross-section, is an angle bar, as best
shown in FIG. 2. Thus, bar or rail 13 has a flat base or leg 16
which is secured to the wall 10 by a double faced adhesive medium
or seal 15. The latter may be a double coated plastic tape, i.e., a
strip of tape having a strong preferably self-sealing adhesive on
each face which bonds the bar or rail 13 to wall 10. This tape 15
may be a little narrower than base element 16 of bar 13, or it may
be of the same width or slightly wider. It should not be very much
wider; otherwise an unsightly or otherwise undesirable adhesive
surface would be exposed along a side edge or edges of the base 16.
The bar 13 preferably is fixed in a vertical position against wall
10 and more or less in line with the outside of tub 11. It has an
inwardly bent or shaped lower part 18, which makes an angle at 19
of about 15.degree. to 30.degree. or so from the vertical. The
purpose of this is to deflect the lower edge portion of curtain 20
inside the tub 11. As at D, FIG. 1, With this arrangement, the
shower compartment above the tub can be made wider as at C, FIG. 1,
than the inside width of the tub, which is usually or often
desirable.
The angle bar 13 has another flange element or leg 17 which extends
from base surface 16 more or less towards the viewer, as seen in
FIG. 1. This element preferably makes an acute angle A with respect
to base element 16, which of course is parallel to wall 10, to
which it is secured. See FIG. 2. Angle A may be as little as
60.degree. of arc or as much as 90.degree., but preferably is
somewhat less than 90.degree., so that curtain attaching means are
enhanced in their holding effect and possibility of shower water
escaping between the side edge of curtain 20 and this element 17 of
the guard base 13 is minimized. A presently preferred value for
angle A is around 70.degree. of arc.
The curtain is provided at suitable intervals, e.g., every 8 to 15
inches or so, with an interlocking fiber type tab 23 or 27. Each
tab 23, FIGS. 1 and 2, or 26, FIG. 3, consists of or comprises a
patch or piece of fabric 22 or 27 provided with upstanding fiber
elements 28 so formed as to interlock with similar fiber elements
25 on patches 24 of similar size and material. See FIG. 4.
The patches or pieces 24 and 27, of fabric faced with upstanding
pile type interlocking fibers form no part, per se, of the present
invention. Materials of this type are well known in the art, one
such, which is rather widely known and used, being marketed
currently under the trade name "Velcro". Other materials having
analogous interlocking properties obviously can be used instead of
or along with "Velcro".
As shown in FIG. 2, tab 23, affixed to the edge of curtain 20,
consists of a backing sheet 22 attached in any suitable manner, as
by adhesive or by rivets or other fastenings, to the edge of
curtain 20. This tab projects far enough from the edge of curtain
20 to bend around the projecting bar element 17 and engage its
upstanding fibers 28 with similar fibers on a patch 24 secured
adhesively (or otherwise) to bar element 17. These interlocking
elements hold the curtain 20 securely; however, they can be pulled
apart readily when desired, that is, they are readily detachable
from each other although ordinarily holding securely together.
In FIG. 3 the tab 26 is shown as folded around and secured to the
bar element 17. In similar fashion, as shown in FIG. 4, it may be
bent U-shape and secured adhesively, or by rivets, staples or the
like, to the curtain 20. Obviously, if metal fastenings are used,
they should be of rustproof material.
FIG. 5 shows an arrangement where a patch 26 of "Velcro" or the
like is secured to one face of the curtain 20 and backed by a patch
of fabric or plastic reinforcing material 29 on the opposite side.
The three layers 26, 20, 29 can be secured together by adhesive or
by mechanical fastenings, as will be obvious.
In FIGS. 7 and 8, a tab 31 is shown which consists of a backing
sheet 32, adapted to be folded about the edge of a curtain 20. It
may also be used on bar element 17, as in FIG. 3, for example. The
rear face (showing in FIG. 7) is coated with a waterproof adhesive,
preferably or self-energizing or pressure sensitive type. The front
face, FIG. 8, bears a patch 34 of projecting interlocking fibers
similar to those mentioned above in other figures of the
drawing.
The tab 31 is folded around the edge of the curtain and secured
adhesively thereto; or if preferred, rivets or other fasteners, not
shown, may be inserted through openings 35 to hold the tabs on the
curtain or on element 17 of rail 13.
At the bottom of the bent rail 13, FIG. 1, a "dam" of plastic
material 37 is placed to prevent water, running down curtain 20 or
wall 10, from flowing outwardly across the top edge of the tub 11.
Preferably, this is a small piece of plastic foam material; one
suitable material is available in the form of a strip or "tape"
about 1/2 inch thick or more. By cementing this on the top of the
side of the tub 11 and snugly against wall 10, leakage under the
bar 13 is prevented. Reference above to a side or end of a tub will
be understood to refer to components without regard to their
relative dimensions.
Obviously, the tabs on curtain 20 and those on rail 13 are located
so as to match each other and are close enough together to prevent
opening of the curtain between them (when the curtain is fastened)
which would permit water to flow outside the tub. As indicated
above, closure at one end of the tub ordinarily will be sufficient
but the curtain may be secured at both ends if desired. In this
case, one end would be left unfastened while the user enters or
leaves the shower enclosure, but fastened while he is inside.
Obviously, the bar 13 extends between the tub and the ceiling
although in many cases it need not go all the way to the ceiling.
The top edge of the curtain may be supported, if required, in and
conventional manner, as by a rod, means for such support not being
shown and not being part of the present invention.
Obviously, many modifications and variations may be made, within
the scope of the invention by those skilled in the art. It is
intended by the claims which follow to cover such modifications and
variations as broadly as the state of the prior art properly
permits.
