SHELF FIXTURE INCLUDING AN ATTACHMENT DEVICE THEREFOR
Abstract
A shelf fixture for attachment to the water supply pipe of a
stall shower is disclosed. The fixture includes a main frame formed
of a single length of steel wire. The length of wire is bent so
that the opposite end portions thereof located at the top of the
frame are anchored together at a point and shaped to form an
attachment device for the fixture. The opposite end portions of the
wire for the attachment device is formed with extension portions
extending downwardly from the anchor point prior to forming
opposing outwardly curved portions which are made to tightly fit
over the pipe. The terminating ends of the curved portions are
located a sufficient distance from the anchor point because of the
extension portions to provide an increased power of action for
spreading the terminating ends to enable the attachment device to
be readily snapped in a secure position over the pipe.

Description
This invention relates to a shelf fixture for use in a shower stall
of a bathroom and more particularly to an improved, low cost
attachment device for such a shelf fixture.
It is generally very useful and convenient to provide shelves in a
shower stall, in addition to the built-in shelves usually provided,
for holding the sundry items presently being marketed for aiding in
bathing and otherwise caring of the hair and body. However, many
persons, and especially women, are discouraged from purchasing
presently available shelf fixtures for such purposes because of the
difficulties encountered in securely attaching or otherwise
providing for mounting such a shelf fixture within the shower
stall. It is therefore evident that there is a need for a low cost
shelf fixture for providing shelves in a shower stall wherein the
bracket for the fixture can be simply and securely attached for
convenient use within the shower stall without the need for any
tools or separate fastening devices.
Accordingly, it is a principle object of this invention to provide
an improved shelf fixture for a shower stall which includes a novel
attachment device therefor.
It is an additional object of the invention to provide a low cost,
simply fabricated shelf fixture for a shower stall which is
designed to have an easy, secure attachment to the water supply
pipe provided therein for the shower head.
A further object of the invention is to provide a new shelf fixture
for a shower stall which includes a main frame formed of a single
length of wire with the integral opposing end portions thereof
shaped and joined to provide an easy attachment device for the
fixture.
These and other objects and features of the present invention will
become better understood through a consideration of the following
description when taken in conjunction with the accompanying
drawings, in which:
FIG. 1 is a perspective view of the shelf fixture of the present
invention;
FIG. 2 is a detailed view of the integrally formed attachment
device provided on the shelf fixture; and
FIG. 3 is a sectional view of the attachment device of FIG. 2 as
taken along line 3--3 thereof.
Referring to the drawings, the fixture 10 of the present invention
comprises a bracket or main frame 11 formed of a single, unbroken
length of relatively heavy guage steel wire. As illustrated in the
drawings the length of wire is formed such that the middle portion
thereof provides a horizontally extending rack or hanger 12 on the
bottom of the frame and the side portions thereof, bent to extend
upwardly from the hanger 12, provide relatively long, parallel,
vertical sides 14a and 14b of the frame 11. Such an arrangement
enables the opposing end portions of the length of wire to be
joined and shaped at the top of the frame 11 to provide an
attachment device 16 which is used for attaching the fixture 10 to
a water supply pipe 17 extending from the wall of a shower stall to
which a shower head (not shown) is connected.
Describing the main frame 11 more particularly, the respective end
portions of the length of wire, after forming the attachment device
16, have lengths or portions 13a and 13b which extend upwardly and
outwardly therefrom in opposite directions and then sharply bend
downwardly to form the relatively long, parallel, vertical sides
14a and 14b of the frame 11. The lower ends of the respective
vertical sides 14a and 14b then bend upwardly to form horizontal
portions 19a and 19b that extend outwardly from each other. The
outer ends of portions 19a and 19b then sharply bend inwardly
toward each other to form the hanger 12 which comprises the middle
portion of the single length of wire forming frame 11.
Provided on the lower half of the parallel vertical sides 14a and
14b of the main frame 11 is a lower shelf 20 and an upper shelf 25.
These shelves are formed of a relatively lighter guage wire than
that used for the main frame 11. Lower shelf 20 is comprised of a
generally rectangular shaped wire structure 21 with the back side
thereof welded to the sides 14a and 14b of the frame 11. A pair of
U-shaped wire members 23 and 24 are attached to the under side of
wire structure 21 with their legs disposed parallel to the sides
21a and 21b thereof and spaced such as to close the opening formed
by the structure 21 and thus prevent articles from passing
therethrough. To further aid in retaining articles on the shelf 20
the opposite sides 21a and 21b of the lower shelf 20 are turned
upwardly, and the respective closed ends 23a and 24a of the
U-shaped members 23 and 24 that extend beyond the outer side of
wire structure 21 are likewise turned upwardly. A wire element 36
formed with a hook 36a on the lower end thereof has its upper end
welded to the back end of the wire structure 21 of the lower wire
shelf 20 at a location centrally between the vertical sides 14a and
14b of the frame. The hook 36a may be used for holding the handle
of a brush, for example.
Upper shelf 25 is similarly formed of a generally rectangular
shaped wire structure 26 with the back side thereof welded to the
sides 14a and 14b of the frame 11. Likewise, a pair of U-shaped
wire members 27 and 28 are attached to the underside of wire
structure 26 with their legs disposed parallel to sides 26a and 26b
thereof and spaced such as to close the opening formed by the wire
structure 26. In a similar manner, so as to aid in retaining
articles on the shelf 25, the opposite sides 26a and 26b of the
upper shelf 25 are turned upwardly and the respective closed ends
27a and 28a of the U-shaped members 27 and 28 that extend beyond
the outer side of wire structure 26 are turned upwardly. Disposed
above the upper shelf 25 are a pair of generally rectangular, open,
wire holders 30 and 31. The back ends of these holders are welded
to the sides 14a and 14b of the main frame 11 and the vertical
spacing of these holders, which are disposed parallel to each
other, is determined, for example, by a steel ball 33 which is
secured by welding between the front ends of the holders. It should
be noted that the sides of the pair of wire holders 30 and 31 are
intended to serve as a side support for the taller articles, such
as a bottle of shampoo, that may be placed on the upper shelf
25.
Reference will next be made to FIG. 2 which shows an enlarged
elevational view of the attachment device 16 for the fixture 10.
Thus as indicated, the respective end portions of the length of
wire used for forming the main frame 11, after being sharply bent
inwardly toward each other and downwardly at the top of the frame
so as to form staight portions 13a and 13b having an angle less
than 90.degree. with the vertical sides 14a and 14b, continue on to
form short, straight portions 15a and 15b that bend inwardly at a
lesser angle until the opposite end portions of the wire contact
each other at a point 40. The opposite end portions of the wire
then bend outwardly to form slightly longer straight extension
portions 18a and 18b extending away from their contact point 40 at
a similarly lesser angle. As illustrated in FIGS. 2 and 3 of the
drawings, the end portions are welded together at their contact
point 40.
After forming the straight extension portions 18a and 18b that
respectively extend angularly outwardly from point 40, the
respective end portions of the wire form opposing outwardly curved
portions 41a and 41b which together form the sides of an opening
for attachment device 16 that generally conforms with the curvature
of the pipe 17. The terminating ends 43a and 43b of the wire then
bend outwardly in opposite directions.
The advantage of the attachment device 16 of the present invention
is that it provides a simple means for enabling a person to attach
the fixture 10 on the supply pipe 17 extending from the wall of the
stall shower in a bathroom without the need of any tools or
separate fastening parts for the fixture 10. The fixture 10 need be
merely placed with the opening formed in its frame 11 between the
parallel vertical sides 14a and 14b positioned in front of the
shower head (not shown) connected on the end of pipe 17. The
spacing of the parallel, vertical sides 14a and 14b of the frame is
made wide enough to enable the fixture 10 to be then easily
positioned over the shower head. The fixture 10 is then moved down
until the open terminating ends 43a and 43b of the attachment
device 15 rest on the pipe 17.
It should be noted that the outwardly bent opposing terminating
ends 43a and 43b are shaped and spaced such as to make it
relatively easy for these ends to be positioned such as to span the
sides of the upper portion of pipe 17. Having so positioned the
attachment device 16 of the fixture 10 over the pipe 17, the
fixture 10 need be merely pulled down with a relatively moderate
force to cause the pipe 17 to be wedged and seated within the
opposing curved portions 41a and 41b. It should be particularly
noted that the opposing terminating ends 43a and 43b of device 16
are located a sufficient distance away from the welded contact
point 40 of the attachment device whereby a relatively small
outwardly directed force on the terminating ends 43a and 43b
resting on pipe 17, obtained by a downward pull on the main frame
11, provides a leverage action which causes the opposing
terminating ends 43a and 43b to spring or deflect out in opposite
directions from point 40 so that the curved portions 41a and 41b of
device 16 can readily snap over the pipe 17. It should thus be
clear that the increased power of action for spreading the
terminating ends 43a and 43b apart is obtained by providing the
extension portions 18a and 18b which locate these ends away from
the welded contact point 40. More particularly, the spacing of the
opposing outwardly curved portions 41a and 41b away from the welded
contact point 40, by the use of extension portions 18a and 18b, is
especially chosen to assure that the terminating ends 43a and 43b
can be easily deflected outwardly such that the neck formed by
points 42a and 42b can slide over the pipe 17, and to further
assure that after the pipe is so positioned in the attachment
device 16, the natural spring back of the end portions toward their
normal position provides for the curved portions 41a and 41b to
have a secure grip on the pipe.
It should now be clear that the attachment device 16 of the fixture
10 can be easily attached onto the pipe 17 and positioned thereon
such that at least the lower portions of the back of the parallel,
vertical sides 14a and 14b of the main frame 11 are supported by
the wall of the shower stall. Further, the attachment device 16
provides a sufficiently strong, gripping action on the pipe 17 to
hold the fixture 10 rigidly in its position against the wall of the
shower stall. It should be further noted that the wire forming the
fixture 10 may be covered with a protective coating 45 by dipping
it in a bath of plastic material, such as vinyl, for example, and
drying the coating in an oven. Such a coating further aids in the
gripping action of the attachment device 16 onto the pipe 17.
While the description has been concerned with a particular
structural embodiment of the present invention, it is to be
understood that many modifications and variations in the
construction and arrangement may be provided for without departing
from the spirit and scope of the invention or sacrificing any of
its advantages. The invention is therefore considered as including
all such possible modifications and variations coming within
legitimate and valid scope of the appended claims.
