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&#39;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 &#39;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&#39;s &#39;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  within a cavity  99  inside the knob, the cavity being sealed by a plug  100 , is tightened onto stud  72  by threadingly engaging the stud within a threaded bore  101  through the nut, thus securing mirror support arm  37  at any selected azimuth angle within a 360 degree circle centered on the longitudinal axis of bushing support arm  70 . 
     Arm adapter  36  of shower head adapter  31  is rotatably secured to tube  41  of the shower adapter, as follows. 
     As shown in FIG. 9, barrel section  68  of arm adapter  36  has formed in front transverse face  102  thereof a front counterbore  103  for receiving a front O-ring  62 . Similarly, rear transverse face  104  of arm adapter  36  has formed thereat a rear counterbore  105  for receiving a rear O-ring  105 A. Barrel  68  of arm adapter  36  is secured to tubular body  41  of shower adapter at an adjustable azimuth angle of bushing support arm  70  with respect to the longitudinal axis of bore  67  through tubular body  41  of shower head adapter  31 , by tightening adjusting nut  56  onto externally threaded front portion  35  of the tubular body, as has been previously described. 
     With the above-described components of device  30  fitted together as shown in FIGS. 5 and 9 and described above, a small portion of flowing warm water supplied to bore  67  of shower head adapter tube from a shower head and conducted therethrough to a shower nozzle is diverted into bore  92  of mirror support arm  37 , by the following path, indicated by arrows in FIG.  5 : Radially outwardly through shower head adapter tubular body orifice  66  into groove  64  in the outer cylindrical wall surface of shower head adapter tubular body  41 , circumferentially within groove  64  to perforation  76  in base  75  of arm adapter boss  69 , radially outwardly through perforation  76  into annular space  106  between the outer cylindrical wall surface  107  of bushing support arm  70  and the cylindrical wall surface  108  of larger, inner radial bore  84  in barrel section  79  of support arm adapter connector assembly  32 ; and axially outwardly through bore  90  in barrel section  79  of the connector assembly into bore  92  of mirror support arm  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,  2 A- 2 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. 
     As may be seen best by referring to FIGS. 1-4,  6 A,  6 B and  7 A,  7 B, mirror device  30  according to the present invention preferably includes a razor holder bracket  140  which is orbitally mounted to mirror assembly  33 . Razor holder bracket  140  includes an arcuately curved shelf  141  which has a concavely curved upper surface  142 ; convexly curved front and rear edge walls  143 ,  144  and straight left and right side edge walls  145 ,  146 . The latter have protruding laterally inwardly therefrom left and right razor handle support slots  147 ,  148 , respectively, which have parallel front and rear laterally disposed edge walls  149 ,  150  and a concave, arcuately curved inner longitudinally disposed edge wall  151 . 
     Razor holder bracket  140  has protruding perpendicularly upwardly from rear edge wall  144  thereof a generally trapezoidally-shaped attachment plate tab  152  which has an arcuately curved, concave upper edge wall  153 , the latter having a thin curved rib  154  of the same shape which protrudes rearwardly from rear surface  155  of the attachment plate. As shown in FIGS. 6A,  6 B, and  7 A, rib  154  is circumferentially slidably held in a semi-circularly-shaped groove  156  formed between front and rear mirror frames  112 ,  113 , near the outer peripheral edge  157  of the mirror frame assembly  33 . 
     A modified razor bracket  440  is shown in FIGS. 22-24, in which attachment plate  152  is replaced by a centrally located pedestal  452  which has a pair of rearwardly and forwardly protruding ribs  454 ,  458  for engaging mirror frame groove  156 . 
     As shown in FIG. 7A, groove  156  is located on a side of mirror frame assembly opposite socket  39 , thus enabling razor holder bracket  140  to be orbitally adjusted to any desired position over the 180 degree range indicated by solid and dashed views of the bracket shown in FIG.  7 A. This arrangement ensures that the razor holder bracket may be adjusted to a pendant position below mirror assembly  33 , for a wide range of orientations of the mirror assembly. 
     FIG. 17 illustrates a first modification of a omni-directionally adjustable rigid arm fogless shower mirror device  30  according to the present invention. Modified device  230  is identical in every respect to basic embodiment  30  described above, except for the replacement of fixed length mirror support arm  37  by a telescopically adjustable arm  237 . The latter includes a radially inwardly located, larger diameter outer tubular section  237 A, and a radially outwardly located smaller diameter inner tubular section  237 B which fits within bore  272  of the outer tubular section and has a bore  292  which is coaxially aligned with and in fluid pressure-tight communication with bore  272 . Radially outwardly located extension arm tube  237 B has fitted into rear opening of bore  292  therethrough a tubular extension arm stop plug  238  which has an inner cylindrical portion  239  that fits tightly within bore  292 , and a radially inwardly located annular flange section  240  which has an outer cylindrical wall surface  241  that fits longitudinally slidably in liquid pressure-tight sealing contact with inner cylindrical wall surface  242  of inner tube portion  237 A of arm  237 . A sleeve-like connecting nut  243  fits over the outer end of inner arm tube  237 A, the connecting nut having a central coaxial bore  244  which longitudinally slidably receives outer arm  237 B. Inner tube portion  237 A contains at the outer end thereof a cylindrical rubber spacer  245  which has a bore  246  that longitudinally slidably receives outer arm tube  237 B, the spacer abutting outer annular flange wall  247  of connecting nut  243 . Spacer  245  has an inner annular wall surface  248  which limits radially outward motion of outer tube arm  237 B, by abutting contact with outer radial surface  246  of flange portion  247  of arm insert  231 . Thus constructed, mirror support arm  237  may be telescopically adjustable from a maximum extension length as shown in FIG. 18A, to a fully collapsed, minimum extension length, as shown in FIG. 18B, as well as to any desired extension length between the minimum and maximum values. 
     FIGS. 19A,  19 B and  21 A,  21 B, illustrate a second modification  330  of the mirror device  30  according to the present invention, in which mirror assembly  33  having a single mirror plate  110  is replaced by a mirror assembly  333  having a concave front mirror plate  310  having a first magnification, e.g., 3× and a flat rear mirror plate  310 A having a different magnification, e.g., 1×. 
     As shown in FIGS. 19A-21B, dual magnification mirror assembly  333  of modified mirror device  330  includes a front annular ring-shaped bezel frame  312  which holds front mirror plate  310 , and a similarly shaped rear or back annular ring-shaped bezel frame  313  which holds rear mirror plate  310 A. Front and rear mirror plates  310 ,  310 A are held in a spaced apart relationship by a circular ring-shaped spacer ring  340  which, as shown in FIGS. 19A and 19C, has circumferentially spaced apart, alternating forward protruding and rearwardly protruding tabs  341 ,  342 , respectively, thus forming between the rear, inner surface  311  of front mirror  310 , and front, inner surface  311 A of rear mirror  310 A, a lenticular-shaped plenum  316  for receiving warm water from a mirror support arm  37 . 
     As shown in FIG. 20A, front frame  312  of dual mirror assembly  333  of dual mirror device  330  has located in a circular groove  343  located near the outer circumferential edge wall  353  of the front frame a plurality, e.g., five, of circumferentially elongated front water relief orifices  344 . Similarly, as shown in FIG. 21A, rear frame  313  has located in a circular groove  363  located near outer circumferential edge wall  373  of the rear frame a plurality, e.g., five of circumferentially elongated, rear water relief orifices  374 . Front and rear water relief orifices  344 ,  374  enable water which has bene introduced into plenum  316  and cooled by warming contact with mirrors  310 ,  310 A to exit from the plenum, allowing a fresh supply of warm water to enter the plenum.
