Abstract
A fogless mirror for use in showers includes a shower arm adapter having a tubular body attachable at one end to a shower arm and at the other end to a shower nozzle; a bore disposed longitudinally through the tubular body conveys warm water from the shower arm to the nozzle, and a small orifice disposed radially through the tubular body diverts a small portion of water conveyed through the bore. A first rotatable coupler rotatably mounted to the shower arm adapter and angularly adjustable in a first plane conducts water diverted from the bore of the tubular body into a first outlet port boss. A second rotatable coupler rotatably mounted to the first outlet port boss and angularly adjustable in a second plane conducts water through a rigid tubular support arm to a mirror support frame, heating the mirror and thereby inhibiting condensation fogging thereof.
Description
BACKGROUND OF THE INVENTION
A. Field of the Invention
The present invention relates to mirrors of the type used by people as an aid in performing certain personal grooming tasks such as shaving and the like. More particularly, the invention relates to a novel mirror device which includes an adapter which is readily attached between an existing shower pipe or arm and shower nozzle, the device including a fogless mirror located at the end of rigid arm adjustably fastened to the adapter and adjustable at any desired position relative to the shower arm, thus enabling a person standing in a shower enclosure to omni-directionally adjust the mirror and obtain a clear, fogless, condensation-free image of himself or herself, in spite of the high humidity produced by warm or hot water issuing from the shower nozzle.
B. Description of Background Art
A substantial number of people utilize mirrors while showering to facilitate performance of personal care functions such as shaving. However, the use of mirrors in showers was formerly relatively limited, because the warm moist air within a shower enclosure tends to quickly condense on the surface of any mirror used in the shower, obscuring an image of a person's face reflected from the mirror surface so completely as to render the mirror practically useless within a few minutes after a shower has begun.
In response to the problem of moisture condensing on a mirror surface and thereby limiting the usefulness of mirrors in high humidity environments, such as shower enclosures and other locations within a bathroom, the present inventor disclosed in U.S. Pat. No. 4,733,468, issued Mar. 29, 1988, a “fogless” mirror which is highly resistant to formation of condensation droplets on the surface of the mirror. The fogless mirror disclosed in the '468 patent utilizes warm water tapped from the warm water supply pipe to a shower head, to heat the surface of the mirror. Since water vapor in a shower produced largely by evaporation, the water vapor is always somewhat cooler than the warm water supplied to the shower head. And, since water vapor will condense only on surfaces which are at lower temperature than the vapor, heating the surface of the mirror precludes fogging of the mirror. Therefore, the fogless mirror disclosed in the present inventor's '468 patent proved to be a highly effective solution to the problem of bathroom mirror fogging, and mirrors utilizing the teachings of that patent have been widely marketed and used.
U.S. Pat. No. 4,836,668, Christianson, Self-Supported, Adjustable Condensation-Free Shower Mirror, discloses a condensation-free shower mirror which includes a T-joint having at one end an internally threaded part adapted to be screwed onto a shower head, at the other end an externally threaded part adapted to threadingly receive a shower nozzle. A hollow flexible arm protruding from a side of the T-joint has attached to an outer end thereof a mirror assembly which receives a portion of warmer water flowing through the T-fitting from the shower head to the shower nozzle, through a flexible tube contained within the flexible arm. The mirror may be adjusted to a desired position relative to the outlet side of the T-fitting, by bending the flexible arm. However, since the exact angular location of the T-fitting side pipe relative to the longitudinal axis of the fitting is constrained by how tightly the fitting is tightened onto the shower head, the exact polar angle of the flexible arm relative to the longitudinal axis of the shower head is not adjustable by the user. Moreover, for orientations of the mirror laterally outwards of the shower head, relatively large torques are exerted on the flexible arm, which can cause the mirror to droop from its adjusted position.
In view of the limitations of prior art adjustable fogless shower mirrors of the type alluded to above, the present inventor conceived of the present invention.
OBJECTS OF THE INVENTION
An object of the present invention is to provide a fogless shower mirror device which includes an adapter that is readily installable between an existing shower head and shower nozzle, including a mirror assembly which is adjustably coupled to a distal end of a rigid arm adjustably coupled at a proximal end thereof the adapter, whereby the mirror assembly is adjustably positionable relative to the shower head and nozzle.
Another object of the invention is to provide a fogless shower mirror device which includes an adapter assembly which is installable between an existing shower head and shower nozzle, the adapter having a T-coupling including a radially disposed side pipe orbitally adjustable with respect to the longitudinal axis of the shower head, and a secondary right angle or L-coupling including an input leg coextensive with the outlet side pipe of the T-coupling, and an outlet arm perpendicular to the outlet side pipe of the T-coupling which is orbitally adjustable in a plane parallel to the longitudinal axis of the shower arm.
Another object of the invention is to provide an omni-directionally adjustable fogless shower mirror which includes an adapter installable between a shower head and shower nozzle, a side arm member which protrudes radially outward from the adapter and which is orbitally adjustable with respect to the longitudinal axis of the adapter and shower head, an elongated rigid mirror support arm which protrudes perpendicularly from an arm connector union rotatably fitted over the side arm member, the union being orbitally adjustable to thereby locate the end of the mirror support arm at any angular position in a plane parallel to the longitudinal axis of the shower head and adapter, and a mirror assembly adjustably coupled to a distal end of the mirror assembly support arm by means of a ball and socket joint, each of the members having communicating water passageways for conveying a portion of the water flowing through the adapter from the shower head to the shower nozzle to be diverted and thereby flow through the side arm and a hollow mirror assembly support arm into a hollow interior space between an inner surface of a mirror plate and a frame holding the mirror plate, the water exiting the hollow interior space of the frame through a plurality of small orifices in the frame after heating the mirror plate and thereby prevent water from condensing on the surface of the mirror.
Various other objects and advantages of the present invention, and is most novel features, will become apparent to those skilled in the art by perusing the accompanying specification, drawings and claims.
It is to be understood that although the invention disclosed herein is fully capable of achieving the objects and providing the advantages described, the characteristics of the invention described herein are merely illustrative of the preferred embodiments. Accordingly, I do not intend that the scope of my exclusive rights and privileges in the invention be limited to details of the embodiments described. I do intend that equivalents, adaptations and modifications of the invention reasonably inferable from the description contained herein be included within the scope of the invention as defined by the appended claims.
SUMMARY OF THE INVENTION
Briefly stated, the present invention comprehends a mirror device for use by a person in a warm, moist environment typical of that in a shower enclosure, the device including a “fogless” mirror mounted on the end of a rigid arm which is adjustable to any suitable orientation and free of potentially image distorting condensation from forming on the surface of the mirror.
An omni-directionally adjustable rigid-arm fogless mirror device according to the present invention includes a shower head adapter assembly which adjustably supports an arm and mirror assembly, and which is readily installable between an existing shower head and shower nozzle. According to the invention, the adapter assembly includes an adapter tube which has at one end thereof a longitudinally disposed, internally threaded section adapted to threadingly receive the outwardly protruding end of a shower head pipe, and at the other end thereof a longitudinally disposed, externally threaded section adapted to be insertably and threadingly received within the internally threaded rear entrance port of a shower spray nozzle.
The mirror device according to the present invention includes a tubular arm adapter member which has a longitudinally disposed coaxial bore which receives the shower head adapter tube. The arm adapter has a radially outwardly protruding, short boss section and a coaxially located, radially outwardly protruding cylindrically-shaped bushing support arm of smaller diameter which has protruding from an outer end thereof a threaded stud. The arm adapter is rotatable around the shower head adapter tube to position the boss section at a desired polar angle with respect to the longitudinal axis of the shower head adapter tube and securable at the desired position by tightening an adjusting nut threaded onto the externally arm adapter. The angular position of the arm adapter is securely held by the engagement of a plurality of triangular lugs which protrude forward from an enlarged diameter rear boss section of the shower head adapter tube, with a plurality of triangularly-shaped notches formed in a rear annular wall surface of the arm adapter. Thus positioned, an annular groove in the outer surface of the shower head adapter tube, which communicates with a bore through the adapter tube by means of a small orifice disposed radially through the groove, is axially aligned with a small perforation disposed radially through the base of the side arm adapter boss section, between the stud support cylinder and the inner cylindrical wall surface of the boss. Thus, a small portion of water under pressure within the bore of the shower head adapter tube is enabled to flow radially outwardly through the adapter tube orifice, into the annular groove in the outer wall surface of the shower head adapter tube, and thence through the axially aligned perforation in the arm adapter.
The mirror device includes an arm assembly that has an elongated tubular mirror support arm which has at a proximate end thereof a perpendicularly disposed tubular arm connector bushing or union which fits rotatably over the bushing support arm that protrudes radially outwardly from the arm adapter. The arm connector bushing is securable at an adjustable orbital angle around the longitudinal axis of the bushing support arm by a locking knob and lock washer tightened onto a threaded stud protruding from the bushing support arm. Also, the arm connector bushing has a larger internal diameter lower tubular portion which has a lower annular face which rotatably contacts an annular gasket which fits within the bore of the arm adapter boss, and is seated on the face thereof. Since the small radially disposed aperture through the base of the arm adapter boss is radially aligned with the inner bore of the arm connector assembly bushing, water exiting radially outwards through the arm adapter perforation travels radially outwardly between a longitudinally elongated annular space formed between the inner cylindrical wall surface of the arm connector assembly bushing and the outer cylindrical wall surface of the stud support cylinder, and thence into a bore longitudinally disposed through the arm.
Located at the distal end of the mirror support arm is a hollow ball, which fits in a fluid pressure-tight seal within a socket which protrudes radially outwards from a circular mirror frame. The ball has disposed longitudinally therethrough a bore which communicates at an inner end thereof with the bore through the arm, and at the outer end thereof with a bore through the mirror frame socket. The latter communicates at an inner radial end thereof with a hollow lenticular space between a reflective front mirror plate and a circular-shaped frame back plate. Warm water which is conducted from the shower head adapter tube to the interior space behind the mirror plate is expelled through a plurality of small relief holes formed in the rear surface of the mirror frame back plate. Heat transferred from the warm shower head supply to the mirror plate by warm water is sufficient to heat the mirror plate to a temperature which prevents condensation of water upon the mirror plate, thus affording a clear, undistorted image of the user.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIGS. 1-16
illustrate a basic embodiment of an omni-directionally adjustable, rigid-arm fogless shower mirror device according to the present invention, while
FIGS. 17-24
illustrate modifications of the basic embodiment.
Referring first to
FIG. 1
, an omni-directionally adjustable rigid arm fogless shower mirror device
30
according to the present invention may be seen to include a shower head adapter assembly
31
, a mirror support arm connector assembly
32
, and a mirror assembly
33
.
As shown in
FIGS. 2A-2C
, shower head adapter assembly
31
has a rear portion
34
which is internally threaded, and adapted to be threadingly tightened onto external threads of a shower head pipe or arm. Shower head adapter assembly
31
also has a front portion
35
which is externally threaded and adapted to be threadingly received within the internally threaded bore of a standard shower nozzle. Thus, as shown in
FIG. 3
, device
30
is readily installed between a shower head and shower nozzle by unthreading the nozzle from the shower head, screwing the shower head adapter assembly
31
onto the shower head, and screwing the shower nozzle onto the shower head adapter.
As may be seen by referring to
FIGS. 5 and 9
and described in detail below, shower head adapter assembly
31
includes an arm adapter
36
which has protruding radial outwardly therefrom a bushing support arm
70
, that is orbital in a P direction around a Y-axis, coincident with the longitudinal axis of the shower head adapter assembly, and securable thereat. Also, an arm connector bushing
85
fitted rotatably over bushing support arm
70
of adapter
36
is rotatable about the longitudinal axis of the bushing support arm
70
, e.g., in direction Q around a Z-axis, as shown in
FIG. 5
, to thus position a mirror support arm
37
protruding perpendicularly outwards from the arm connector bushing to any orbital angle in a plane parallel to longitudinal axis Y of the shower head adapter assembly.
As shown in
FIG. 6A
, mirror support arm
37
has at an outer end thereof a ball
38
which is rotatably and frictionally received within a socket
39
which protrudes radially outwards from a circular mirror frame
40
of mirror assembly
33
. Socket
39
and mirror frame
40
are pivotable around an X axis in the direction R, rotatable around a Y-axis in the direction S, and pivotable about the Z-axis in the direction T. With the foregoing construction, mirror assembly
33
is adjustable to any polar angle orientation with respect to a shower head, e.g., from a location on the right side of the shower head, as shown in
FIGS. 2C and 3
, to a location on the left side of the shower head, as shown in FIG.
4
. Moreover, as described above, mirror assembly support arm
37
is rotatable about the axis of bushing support arm
70
disposed perpendicularly to the longitudinal axis of the shower head adapter, thus positioning mirror assembly
33
in a fore-and-aft direction forwardly or rearwardly with respect to the shower head. Provided with the foregoing degrees of freedom, mirror assembly
33
is adjustable to any desired position relative to a shower head.
Referring now to
FIGS. 5 and 9
, it may be seen that rear portion
34
of shower head adapter assembly
31
includes a longitudinally elongated, generally cylindrically-shaped tubular body
41
which has located at a first, rear longitudinal end thereof an enlarged diameter boss section
42
. Rear boss section
42
has formed in an inner cylindrical wall surface
43
thereof a helical thread
44
which is of the proper size and pitch to threadingly receive an externally threaded outer end portion of a standard shower arm which device
30
is intended to be used with. Preferably, as shown in
FIG. 11
, boss
42
has formed in an outer cylindrical wall surface
45
thereat a pair of diametrically opposed notches
46
which have longitudinally and transversely disposed, parallel flat base surfaces
47
which comprise a pair of planes adapted to be engagingly received within a pair of opposed flat jaws of a wrench, thus facilitating tightening the adapter tube onto a shower head.
As may be seen best by referring to
FIGS. 9 and 10
, tubular body
41
of shower head adapter assembly
31
has an intermediate longitudinally elongated portion
48
located between rear boss
42
and front externally threaded portion
35
. Intermediate longitudinal portion
48
of tube
41
has a smooth outer cylindrical surface which is of slightly smaller outer diameter than the inner diameter of a smooth cylindrical bore
50
disposed longitudinally through arm adapter
36
, thus enabling the arm adapter to rotate freely around tubular body
41
.
As may be seen best by referring to
FIGS. 10 and 12
, boss
42
of tubular body
41
has formed in front annular surface
51
thereof a plurality, preferably four, of circumferentially spaced apart, longitudinally or axially forwardly projecting, triangular elevation view teeth
52
. As may be best understood by referring to
FIGS. 5
,
9
, and
14
, a rear annular surface
53
of arm adapter
36
has formed therein a plurality of triangularly-shaped, longitudinally or axially forwardly disposed notches
54
. Each notch
54
has the general shape of an equilateral triangle, and is circumferentially spaced apart from adjacent notches by a flat, uncut portion
55
of rear annular wall surface
53
that has the same circumferential length as the base of the notches. Although the exact number of notches
54
is not critical, an example embodiment of device
30
utilizes 20 notches.
As shown in
FIGS. 5
,
9
and
16
, shower mirror device
30
includes an adjusting nut
56
, which has an inner cylindrical wall surface
57
that contains a helically threaded portion
58
forming a threaded bore
59
which is adapted to threadingly engage front externally threaded portion
35
of shower head adapter assembly tubular body
41
. Thus, as shown in
FIGS. 2A
,
2
B and
5
, when front surface
51
of boss
42
is pressed axially against rear surface
53
of arm adapter
36
by tightening adjusting nut
56
onto adapter assembly tubular body
41
, teeth
52
are pressed into notches
54
, thereby enabling the arm adapter to be fixed rotatably on adapter assembly tubular body
41
at any one of 20 equally spaced circumferential intervals, i.e., at 18-degree increments.
As shown in
FIG. 9
, rear annular wall surface
60
of adjusting nut
56
has cut axially inwardly therefrom a smooth counterbore
61
adapted to receive an O-ring
62
, the function of which will be described below.
Referring now to
FIGS. 9 and 10
, it may be seen that outer cylindrical wall surface
63
of tubular body
41
of shower head assembly
31
has formed therein near the rear end of intermediate portion
48
thereof an annular groove
64
. Also, tubular body
41
has formed in cylindrical wall
65
thereof a small radially disposed, circular cross-section orifice
66
which communicates between outer cylindrical wall surface
63
of the tubular body and a coaxial bore
67
disposed longitudinally through the length of the tubular body. The diameter of tube orifice
66
is substantially smaller than that of bore
67
of tubular body
41
, e.g., 0.060 inch for a tubular body bore diameter of 0.584 inch.
Referring now to
FIGS. 13
,
14
and
15
in addition to
FIGS. 5 and 9
, it may be seen that arm adapter
36
has a longitudinally disposed, a cylindrically-shaped barrel section
68
, and radially outwardly projecting from the barrel section a short, circular cross-section connector assembly boss
69
coaxially centered around a smaller diameter cylindrically-shaped bushing support arm
70
. Bushing support arm
70
has protruding longitudinally outwardly from an outer transverse face
71
thereof a coaxially centered, threaded stud
72
.
As shown in
FIG. 9
, connector assembly boss
69
has protruding longitudinally inwards from outer transverse face
73
thereof an axially elongated, concentric annular groove
74
. Groove
74
has a flat, transversely disposed annular ring-shaped base
75
which coaxially encircles bushing support arm
70
. Base
75
of annular groove
74
has formed through its thickness dimension a radially disposed perforation
76
which penetrates cylindrical wall
77
of barrel section
68
of arm adapter
36
into a cylindrical bore
50
disposed longitudinally through the barrel section. Preferably, perforation
76
has the same diameter as that of tube orifice
66
, e.g., 0.060 inch.
As may be seen best by referring to
FIGS. 5 and 9
, bushing support arm
70
which protrudes radially outwards from barrel section
68
of arm adapter
36
rotatably supports mirror support arm connector assembly
32
, in a manner which will now be described.
As shown in
FIGS. 5 and 9
, mirror support arm connector assembly
32
includes a generally cylindrically-shaped arm connector bushing or barrel section
79
. Barrel section
79
has protruding longitudinally inwardly from outer transverse face
80
thereof an outer bore
81
which has a slightly larger diameter than the outer diameter of bushing support arm
70
, which is rotatably received within the outer barrel bore. Also, barrel section
79
of arm connector assembly
32
has formed in inner transverse face
82
thereof a longitudinally outwardly protruding annular flange
83
in which is formed an inner longitudinally disposed bore
84
. Inner bore
84
has a larger diameter than outer bore
81
, is coaxially aligned therewith, and joins the outer bore about midway through the length of barrel section
79
, forming therewith an annular ring-shaped joint flange
85
.
Referring still to
FIGS. 5 and 9
, it may be seen that mirror support arm connector assembly
32
includes a cylindrical boss section
86
which protrudes radially outwards from barrel section
79
of the connector assembly. Boss section
86
has protruding longitudinally inwardly from outer transverse face
87
thereof a cylindrical bore
88
, which has a longitudinally inwardly located, annular ring-shaped base
89
in which is formed an inner bore
90
of smaller diameter than outer bore
88
. Outer bore
88
is adapted to receive in a relatively tight fit the outer cylindrical wall surface
91
of tubular mirror support arm
37
, which has an inner transverse face
91
A which seats on annular base
89
of bore
88
. Mirror support arm
37
has a bore
92
which communicates with inner bore
90
of mirror support arm boss section
86
, and is permanently fastened in a fluid pressure-tight seal within outer bore
88
of the boss section by any convenient means such as adhesive bonding or welding.
As shown in
FIGS. 5 and 9
, barrel section
79
of mirror support arm connector assembly
32
is rotatably secured to bushing support arm
70
of arm adapter
36
, as follows. A resilient gasket washer
93
is placed coaxially over bushing support arm
70
, and pushed axially inwardly over the bushing support arm to seat on annular ring-shaped base
75
at the bottom of annular groove
74
in connector assembly boss
69
of arm adapter
36
. Bushing support arm
70
of arm adapter
36
is then inserted into rear inner bore
84
of arm connector assembly barrel section
79
, and moved axially outward until longitudinally outwardly protruding annular flange
83
of barrel section
79
seats on the outer, upper surface of gasket washer
93
. An outer resilient gasket washer
94
is then slipped over stud
72
protruding radially outwardly of outer transverse face
80
of arm connector assembly barrel section
79
, and a cup-shaped rigid lock washer
95
is fitted over the outer transverse face of arm assembly barrel section
79
by inserting the outer end of stud
72
through a central coaxial perforation or bore
96
through the lock washer. Finally, an adjusting knob
97
which contains a coaxially located hex nut
98

37
. The construction of mirror assembly
33
, and the manner of conducting warm water from bore
92
into contact with a mirror held within the mirror assembly, to thereby warm the mirror and prevent condensation fogging thereof, will now be described.
Referring now to
FIGS. 1

C,
6
A-
6
B,
7
A,
7
B, and
8
A and
8
B, it may be seen that mirror assembly
33
includes a flat circular mirror
110
having a reflective surface
111
. Preferably, mirror
110
is made of glass, the rear surface
111
of which is reflective. Optionally, flat mirror
110
is replaced by a magnifying mirror
110
A having a concave reflecting surface
111
A. Mirror
110
is held between a front annular ring-shaped bezel frame
112
and a circular disk-shaped rear or back frame
113
which has a convex, arcuately curved rear surface
114
. As shown in
FIGS. 6A and 6B
, rear frame
113
has over a major portion of its area a uniform thickness. Thus, rear mirror frame
113
has a concave front surface
115
which forms with rear surface
111
of mirror
110
a hollow, lenticular-shaped interior space or plenum
116
. As shown in the figures, mirror
110
is seated on the upper surface
118
of annular ledge
117
which protrudes forward from back frame
113
near the outer peripheral edge of the back frame, and is retained thereat by an annular bezel flange or lip
119
which protrudes rearwardly from front frame
112
. Front and rear frames
112
,
113
are secured together by means of interlocking pins
120
and recesses
121
, and by screws
122
threaded within bosses
123
.
As shown in
FIGS. 6A
,
6
B,
7
A,
7
B, and
8
A,
8
B, front and rear frames
112
,
113
have protruding radially outwardly therefrom front and rear, generally hemispherically-shaped socket halves
124
,
125
, respectively. Socket halves
124
,
125
have formed therein generally hemispherically-shaped concave cavities
126
,
127
which depend inwardly from flat, mid-plane mating inner surfaces
126
A,
127
A, respectively, of front and rear frames
112
,
113
. Thus, when front and rear frames
112
and
113
are fastened together as shown in
FIGS. 6A and 6B
, confronting concave cavities
126
,
127
of socket halves
124
125
form therebetween a generally spherically-shaped socket
39
which clampingly receives ball
38
at the outer end of mirror assembly support arm
37
. Socket
39
has disposed radially inwardly therefrom a passageway
129
which communicates with plenum
116
rearward of mirror
110
. Also, ball end
38
of mirror assembly support arm
37
has disposed longitudinally or axially therethrough an outer bore
130
which communicates at an outer radial end thereof with bore
92
through mirror assembly support arm
37
, and at an inner radial end thereof with an enlarged diameter, inner bore
131
of larger diameter than the outer bore. Inner bore
131
of ball
38
communicates with an enlarged diameter outlet bore
132
formed in socket
39
, and outlet bore
132
communicates with passageway
129
to plenum
118
. Thus, warm water conveyed through bore
92
of mirror support arm
37
is conducted into outlet bore
132
of socket
39
, for arbitrary rotation relative angles between socket
39
and ball
38
, thus ensuring that warm water flow is enabled to flow from bore
92
into mirror assembly plenum
116
for such arbitrary relative orientations.
As shown in
FIG. 6B
, inner facing surfaces
126
A,
127
A of socket halves
124
,
125
, have formed therein upper and lower transversely disposed semi-circularly-shaped, rectangular cross-section grooves,
135
,
136
, respectively. When front and rear frame
112
,
113
are fastened together, as shown in
FIG. 6A
, semi-circular grooves
135
,
136
form an annular ring-shaped groove
137
in which is fitted a resilient flat annular ring-shaped sealing washer
138
that forms a water-tight seal between socket
39
and ball
38
.
As shown in
FIG. 8A
, back frame
113
of mirror assembly
33
has located on a circle near the outer circumferential edge wall
133
of the back frame a plurality, e.g., five, of circumferentially elongated water, oval-shaped relief orifices
134
, for enabling water which has been introduced into plenum
116
and cooled by warming contact with mirror
110
, to exit the plenum, allowing a fresh supply of warm water to enter the plenum.
