Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a bathroom hanger, and more
particularly to a bathroom hanger in combination with a suction
disk assembly, wherein the suction disk assembly is able to firmly
engage with a bathroom wall.
[0003] 2. Description of Related Art
[0004] Bathroom hangers, for hanging towels and various purposes,
are commonly seen in an ordinary family bathroom. In order to be
mounted on a bathroom wall, a majority of bathroom hangers use
suction disks to suck on the wall. The advantages of using the
suction disk instead of a screw or a nail are of being able to
provide attachment without damaging the wall or using special
tools. Further comparing using the suction disk and a sticky pad to
fix the bathroom hanger on the wall will find that the suction disk
is able to be easily released from the wall, not like the sticky
pad which may only be released under a strong force such that the
sticker will not be reusable.
[0005] However, the disadvantage of using a suction disk for the
bathroom hanger is that the suction disk can not provide a secure
attachment of the bathroom hanger to the bathroom wall. For
example, in operation the moistened suction disk is pushed against
the wall such that air between the disk and the wall is expelled to
create a low pressure that provides the attachment force. This low
pressure is often imperfect and gradually fails whereby the
bathroom hanger falls from the wall, leading to a mess and
irritation of the users.
[0006] To overcome the shortcomings, the present invention tends to
provide a bathroom hanger in combination with a suction disk to
mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
[0007] The primary objective of the present invention is to provide
a bathroom hanger in combination with a suction disk assembly, such
that the suction disk assembly is able to reliably suck to a
bathroom wall, and thus the bathroom hanger is securely mounted on
the bathroom wall.
[0008] Another objective of the present invention is to provide a
bathroom hanger in combination with a suction disk assembly which
is able to provide holding of a showerhead, hanging towels, and
placing items such as soap, shampoo, sponge . . . etc..
[0009] Other objectives, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0019] With reference to FIG. 1, a bathroom hanger in combination
with a suction disk assembly in accordance with the present
invention includes two suction disk assemblies (10), a telescopic
tube (20), two arms (30), two shelves (50), and a showerhead holder
(70).
[0020] With reference to FIG. 2, the suction disk assemblies (10)
are identical and each has a suction disk (101) with a stud (1011)
extending outwardly from a center of a top surface of the suction
disk (101). A cap (102) has a through hole (1021) centrally defined
therein with a configuration that is able to allow the stud (1011)
to freely extend therethrough. A knob (103) has a stud hole (1031)
defined in a bottom surface of the knob (103) and a tapered hole
(1032) extending through a head of the knob (103) in a direction
perpendicular to the stud hole (1031).
[0021] The telescopic tube (20) has two tapered ends (201) with a
configuration to mate the tapered holes (1032) and each tapered end
has ridged outer surface (B shown in FIG. 4).
[0022] With reference to FIG. 4, the arms (30) are identical and
each has a joint (40) mounted on one end of the arm (30). A stepped
bore (41) with a spring ball combination (42) retained inside is
defined in the joint (40). A second through hole (44) extending
perpendicularly to the step bore (41) is also defined in the joint
(40) and communicates with the stepped bore (41).
[0023] The shelves (50) are identical and each has a first
positioning device (51) extending from a corner of the shelf (50),
and the first positioning device (51) has a first eccentric ring
(511) rotatably mounted on the first positioning device (51). The
telescopic tube (20) is able to extend through the positioning
device (51) and the eccentric ring (511). A retaining sucking cup
(501) is mounted on a side wall of the shelf (50) to retain the
shelf (50) from rotating.
[0024] The showerhead holder (70) is mounted to a second
positioning device (71) which has a second eccentric ring (711),
wherein the second positioning device (71) is the same as the first
positioning device (51).
[0025] With reference to FIGS. 3A, 3B, 3C, and 3D, when applying
the suction disk assembly (10) onto a bathroom wall, a bottom
surface of the suction disk (101) first completely engages the
wall, then the cap (102) is disposed onto the top surface of the
suction disk (101) with the stud (1011) extending through the
through hole (1021). The knob (103) is screwed onto the suction
disk (101) by threadingly engaging the stud (1011) and the stud
hole (1031). When screwing the knob (103) onto the suction disk
(101), the bottom surface of the knob (103) first engages a top
surface of the cap (102) defining the through hole (1021), and
further screwing the knob pushes the cap (102) to the suction disk
(101) thus exerting force on an edge (1022) of the cap (102) that
engages with the suction disk (101). As the stud (1011) is drawn
into the stud hole (1031) but the circumference of the suction disk
(101) is held in place by the edge (1022) of the cap (102), a
central portion of the suction disk (101) is pulled away from the
wall to create a low pressure. By varying the depth of the stud
(1011) in the stud hole (1031), the intensity of the low pressure
can be varied.
[0026] With reference to FIG. 4, the arms (30) are clamped on the
telescopic tube (20) by the spring ball combination (42) abutting
the ridged surface (B) of the telescopic tube (20).
[0027] With reference to FIGS. 5A and 5B, the shelves (50) are
clamped on the telescopic tube (20) by rotating the first eccentric
rings (511) to clamp the ridged surface (B) of the telescopic tube
(20) between an inner surface (A) of the first eccentric rings (5 1
1) and an inner surface (C) of the first positioning device (51).
The showerhead holder (70) is also clamped on the telescopic tube
(20) by rotating the second eccentric ring (711) and clamping the
telescopic tube (20) between the second positioning ring (711) and
the second positioning device (71) in a same manner used in the
first eccentric ring (511) and the first positioning device
(51).
[0028] To continue assembling the bathroom hanger, the telescopic
tube (20) together with the arms (30), the shelves (50), and the
showerhead holder (70) are clamped between the suction disk
assemblies (10) which are sucked on the bathroom wall with the
tapered ends (201) of the telescopic tube (20) abutting an inner
surface defining the tapered holes (1031) of the knobs (103). The
retaining sucking cups (501) of the shelves (50) are also sucked to
the bathroom wall to provide retaining of the shelves (50) and thus
prevents rotating of the shelves (50).
[0029] From the above description, it is noted that the invention
has the following advantages:
[0030] 1. the suction disk assembly is able to securely suck and
remain sucked on the bathroom wall such that the bathroom hanger is
able to be securely retained on the wall by the suction disk
assemblies.
[0031] 2. the bathroom hanger is able to fulfill need of a
multi-purpose bathroom hanger on which it is able to hang towels,
holding showerhead, and place items such as soap, shampoo . . .
etc..
[0032] It is to be understood, however, that even though numerous
characteristics and advantages of the present invention have been
set forth in the foregoing description, together with details of
the structure and function of the invention, the disclosure is
illustrative only, and changes may be made in detail, especially in
matters of shape, size, and arrangement of parts within the
principles of the invention to the full extent indicated by the
broad general meaning of the terms in which the appended claims are
expressed.
