Description
BACKGROUND OF THE INVENTION
This invention relates indirectly to shower stalls or bath coves,
shower water sprays and hanging shower curtains; and specifically
to apparatus for holding a side edge of a hanging shower curtain in
line contact with an enclosure wall, to prevent shower water spray
from splashing outwardly beyond the shower curtain.
It is common practice to equip a bath cove with an overhead
horizontal shower curtain rod, to which a hanging flexible shower
curtain is attached by means of curtain hook rings. Such rings are
slidable along the curtain rod so that the shower curtain may be
moved laterally by hand, for convenient access to the bath cove,
and then permit sliding of the shower curtain to closed position
across the open side of the bath cove.
Ordinarily, one vertical edge of the shower curtain is positioned
adjacent a bath cove wall from which a shower water spray nozzle
projects. When the shower water spray is turned on, the shower
curtain usually billows inwardly and the edge thereof moves away
from the said wall, leaving a gap through which sprayed water
escapes. The relevant prior art discloses several devices intended
for detachably holding an edge of a shower curtain against an
adjacent bath cove wall, to prevent such shower water spray
leakage. Such devices are generally inadequate or inefficient; sre
not durable and long lasting; are unsuitable for the average
homeowner to apply so as to function effectively; or are complex
and costly to manufacture and market.
SUMMARY OF THE INVENTION
In one preferred embodiment, this invention comprises a wall
attachment bar adapted to be attached vertically to a bath cove
wall, in vertical alignment with a marginal edge of a hanging and
laterally slidable shower curtain. A lower portion of the said
curtain edge is splined longitudinally to a connecting bar, which
may be attached to or disconnected by hand from the said wall
attachment bar with facility. The connecting bar, when attached to
the wall attachment bar, retains a lower portion of the curtain
edge in line contact with the adjacent end wall of the bath cove,
and prevents shower water spray from egressing past the retained
edge of the shower curtain. The spline which fastens the marginal
edge of the shower curtain to the connecting bar may be easily
applied by hand and the curtain edge may be adjusted lengthwise of
the connecting bar after the latter is interconnected with the wall
attachment bar, so that the shower curtain will hang uniformly.
A primary object of the invention is to provide a retainer adapted
for vertical attachment in part to a bath cove wall, and in part to
a marginal edge of a hanging shower curtain, for holding the latter
in line contact with the said wall, and whereby the shower curtain
may be released by hand with facility from such closed
position.
Another object of the invention is to provide a shower curtain
marginal edge retainer comprising a wall attachment bar adapted to
be vertically affixed to a bath cove wall, and a curtain edge
connecting bar adapted to overlay and mechanically interlock with
the wall attachment bar, in such manner that the connecting bar may
be attached to or disconnected from the wall attachment bar with
facility, and without the use of hand tools.
An additional object is to provide novel, effective and practical
means for fastening a portion of one marginal edge of the shower
curtain to a connecting bar, in such wise that the said edge of the
shower curtain may be slidably adjusted vertically by hand in
relationship to the attached connecting bar, so that the shower
curtain will hang uniformly.
A still further object of the invention is to provide novel spline
means for detachably fastening a marginal edge of a shower curtain
to a connecting bar, whereby the said marginal edge is interlocked
lengthwise of and to the connecting bar, in such manner that shower
water spray will not egress between the latter and the curtain.
The preceding object is further characterized in that the spline
means may be removed by hand from the marginal edge of the shower
curtain and the connecting bar, with facility and without the use
of hand tools, so that the shower curtain may be easily and quickly
detached for cleaning or replacement purposes.
To the accomplishment of these and related objects as shall become
apparent as the description proceeds, the invention resides in the
formation, arrangement and combination of parts as shall be
hereinafter more fully described, illustrated in the accompanying
drawings, and pointed out in the claims hereunto appended.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENT
This shower curtain edge retainer may be applied to a bath shower
stall and shower curtain, or to a bath tub enclosure wall and
shower curtain. In the interests of brevity, the common definition
"bath cove" is used in this disclosure, and is intended to
generally designate any such bathing facility.
In FIG. 1 of the drawings, the numeral 10 designates part of an
exposed side of a standard type bath tub, the two ends and opposite
side of which are surrounded by a wall which defines a bath cove.
An end 10a of the bath tub adjoins the wall 12 of the bath cove.
The numeral 14 designates a standard type shower water spray
nozzle, which is depicted in dotted lines, and is located adjacent
to the wall 12. The numeral 16 designates a fabric or flexible
plastic shower curtain of the standard hanging type, the top end
16a of which is carried by a plurality of ring type curtain hooks
16b, laterally slidable on an overhead curtain rod 16c. Ordinarily,
the shower curtain 16 hangs with its lower end 16d near to and
inside of the exposed side of the bath tub 10. The shower curtain
16, the curtain hooks 16b and the curtain rod 16c exemplify
conventional shower stall or bath tub equipment.
This shower curtain marginal edge retainer includes two main
components in the form of a wall attachment bar 18 and a connecting
bar 20, which are schematically shown in FIG. 1. In FIG. 2, the
surface of the aforesaid wall of the bath cove is represented by
the solid line 12, and the bars 18 and 20 are drawn to a greatly
magnified scale relative to FIG. 1. The overall length of the
retainer and in turn the length of the bars 18 and 20 shall
preferably be not less than 20 inches, and not more than 32 inches.
A length of 24 inches has proven to be generally satisfactory.
Referring now to FIGS. 2 and 5, the bar 18 may be in the form of an
anodized or painted aluminum extrusion of channel profile, having a
longitudinal recess 18a and an inside surface 18b. In the process
of manufacture, a contact adhesive coated elastomeric tape 22 is
bonded to the bar inside surface 18b and extends lengthwise of the
recess 18a. The outside surface 22a of the said tape carries a
contact adhesive coating covered by a peel off protective strip.
The width of the tape 22 shall be sufficient to provide a durable
bond to the related surface of the wall 12 of bath cove, and to
hold the bar 18 against accidental dislodgement. A plurality of
hooks 24 are lanced outwardly from the bar 18 and serve to support
the detachable connecting bar 20.
The connecting bar 20 may be in the form of a rigid plastic
extrusion such as P.V.C., and generally of channel profile. The web
20a is formed with lateral flanges 20b and 20c, which define a
longitudinal channel shaped recess 20d, shown in FIG. 3. This
recess overlays and straddles the wall attachment bar 18 when the
connecting bar 20 is applied thereto. Apertures 26 are formed in
the web 20a of the connecting bar 20 to receive and align with the
hooks 24 of the wall attachment bar 18, as is shown in FIGS. 4 and
5. The hooks 24 of the bar 18 and the apertures 26 in the bar 20
may be so formed and spaced that the bar 20 may be connected to the
bar 18 as is shown in FIGS. 1 and 4, or the bar 20 may be turned
end to end, for use at the right side or edge of a shower curtain.
Accordingly, the retainer may be used at either side or edge of a
shower curtain, and right and left hand retainers are not
required.
Referring again to FIGS. 2 and 3, a flange 20e extends lengthwise
of the bar 20 and in part defines a longitudinal groove 28 in the
bar 20, in which the marginal edge 16e of the shower curtain 16 is
retained by a flexible and deformable spline 30 extending
lengthwise of the groove 28. The flanges 20c and 20e have angular
faces 20f, and shoulders 20g, which define part of the groove 28.
The spline 30 may be of tubular cross sectional shape, and may be
formed of flexible P.V.C., in the 60 - - 70 durometer range. The
external diameter of the tubular spline 30 shall be slightly less
than the internal width of the groove 28 at its approximate
transverse center, which is exemplified by the location of the
center of the said spline in FIG. 2. Bearing in mind that fabric or
plastic shower curtains may vary in a gauge thickness range from
0.006 inches to 0.012 inches, the dimensional proportions of and
the flexible and deformable characteristics of the materials
forming the bar 20 and the spline 30 may be evaluated and selected,
so that the marginal edge 16e of the shower curtain 16, and the
spline 30, may be pressed by hand into and longitudinally of the
groove 28. As such insertion is made, the bar flange 20e flexes
slightly and opens the groove 28.
It is preferable that the inserted spline 30 and the flange 20e
shall be slightly deformed, to interlock the shower curtain
marginal edge 16e and whereby the two shoulders 20g will impede
dislodgement of the said curtain edge and the spline, and so that
the connecting bar 20 may be shifted by hand under slight
retractile effort along the said curtain edge, for subsequent
hanging adjustment of the shower curtain 16. It is important that
the frictional relationship between the curtain edge 16e and the
connecting bar 20 be such that the latter will not drop off of the
shower curtain 16 when the connecting bar is disconnected by hand
from the wall attachment bar 18.
A knob 32 may be attached by the screw 34 to the web 20a of the bar
20. The said knob provides for convenient hand engagement with the
connecting bar 20, so that it may be pulled upwardly to disengage
same from the hooks 24 of the wall attachment bar 18. The two
attachment hooks 24 shown in the drawings will adequately support a
connecting bar between 20 inches and 24 inches in length. For
longer bars, an additional attachment hook may be provided and
located midway between the said two hooks.
This shower curtain marginal edge retainer may be sold in a compact
package container enclosing a subassembly comprising a wall
attachment bar 18 with attached adhesive contact tape 22, a
connecting bar 20 attached to the said wall attachment bar, and a
pre-cut spline 30 extending lengthwise of the connecting bar groove
28. These components may be applied respectively to the wall of a
bath cove, and to a marginal edge of a shower curtain, by hand
without the use of tools.
Before applying the wall attachment bar 18 to the wall of a bath
cove, the wall surface should be washed to remove any foreign
matter. The connecting bar 20 shall be disconnected from the wall
attachment bar 18, and the spline 30 shall be withdrawn endwise
from the groove 28 of the said connecting bar. The peel off
protective strip shall be removed from the contact adhesive coating
22a of the tape 22 on the wall attachment bar 18. The said bar
shall then be affixed to the wall 12 of the bath cove, with the
aforesaid tape adhesive coating 22a bonded thereto. The wall
attachment bar 18 shall be applied vertically, in such manner that
the flange 20e of the connecting bar 20 shall align substantially
vertically with the hanging marginal edge 16e of the shower curtain
16, and the lower end 18c of the wall attachment bar 18 shall abut
the underlying top 10b of the end of the bath tub 10. The
connecting bar 20 may then be attached by hand to the wall
attachment bar 18, and the marginal edge 16e of the shower curtain
may be pencil marked where one end of the said connecting bar
aligns horizontally with the said marginal edge of the shower
curtain, so that the relationship of the connection bar 20 may be
identified.
The hanging shower curtain 16 may then be disconnected from its top
end supporting hooks 16b. The connecting bar 20 may be supported on
a table, with the groove 28 facing upwardly. The magrinal edge 16e
of the shower curtain may then be placed over and aligned with the
said groove, and the end of the connecting bar may be registered
with the previously marked curtain marginal edge. The spline 30 may
be placed on the said marginal edge over the groove 28, and then
pressed firmly by hand into the said groove. The curtain edge 16e
and the spline 30 should snap into the groove, but if difficulty is
experienced, the spline may be pressed inwardly and seated by a
blunt instrument, such as an end of a teaspoon. The inclined
surfaces 20f of the connecting bar 20 serve as guide means to
facilitate insertion of the said marginal edge and the spline.
The shower curtain 16 may then be attached to its top end
supporting hooks 16b, and the connecting bar 20 may be attached by
hand to the wall attachment bar 18. In such position, as is shown
in FIG. 2, the marginal edge 16e of the shower curtain 16 is in
contact with the related surface of the wall 12. Note that the
marginal edge 16e of the shower curtain is in part wrapped around
the spline 30, and also extends laterally across the flange 20e of
the connecting bar 20, thus concealing the latter from view. The
curtain edge hanging above the connecting bar 20 may be pressed
laterally by hand against the adjacent surface of the wall 12, to
close off any gap through which shower spray water might egress. If
it is desired to move the shower curtain 16 away from the wall 12,
the connecting bar 20 may be disconnected by hand from the wall
attachment bar 18. When so disconnected, the connecting bar 20
remains attached to the shower curtain.
If the marginal edge 16e of the shower curtain does not hang true
and taut, it may be slidably adjusted up or down by hand relative
to the attached connecting bar 20. After detachment of the
connecting bar 20 from the wall attachment bar 18, and detachment
of the shower curtain from its supporting hooks 16b, the marginal
edge 16e of the shower curtain, and the spline 30 may be withdrawn
endwise by hand from the connecting bar groove 28, so that the
shower curtain may be washed or cleaned free from encumberance.
In FIG. 1 of the drawings, the lower left corner of the shower
curtain has been broken away, to show the relationship of this
curtain edge retainer with the top end 10b of the bath tub 10 and
the bath cove wall 12. When a standard type shower curtain with
attached connecting bar 20 is applied, the lower left corner of the
shower curtain abuts and lays over the top end 10b of the bath tub
10, generally conforms with its curvature, and extends downwardly a
few inches into the bath tub.
It is noteworthy that the connecting bar 20 holds the marginal edge
16e of the shower curtain in line contact with the related surface
of the bath cove wall 12, as is shown in FIG. 2. After the
connecting bar 20 is attached to the wall attachment bar 18, the
upper part of the marginal edge 16e may be pushed laterally into
closed contact with the adjacent wall 12 of the bath cove, to close
off any gap through which shower water spray might egress.
Frictional contact of the connecting bar 20 with the marginal edge
16e of the shower curtain 16, and with the hooks 24 of the wall
attachment bar 18, serves to hold the upper part of the marginal
edge of the shower curtain taut and in line, thus impeding water
spray splash out.
