Description:
BACKROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    This invention generally relates to beverage dispensers and more particularly to beverage dispensers with faucet assemblies for manual dispensing of beverage from the bottom of the dispenser body and to faucet guards of such faucet assemblies  
           [0003]    2. Discussion of the Prior Art  
           [0004]    Beverage dispensers of the type with a hollow body for containing the beverage and a base for supporting the body above a support surface such as a counter top and which also have a manually operated faucet for dispensing beverage from the bottom of the hollow body are well known. In known hot beverage dispensers, such faucets are connected to a horizontal, radial, faucet pipe extending outwardly from a lower portion of a dispenser housing located beneath the bottom of the hollow body. The faucet pipe is connected to a vertical drainpipe that extends downwardly from an outlet at the lowermost surface of the bottom of the hollow body. Both the faucet pipe and the drainpipe are generally made of relatively rigid, stainless steal or other like metal alloy or other material that is relatively rigid and self-supporting and which is impervious to hot corrosive liquids and steam. Unfortunately, in known hot drink dispensers, the connection between the stainless steel drainpipe and the stainless steel faucet pipe is made by means of separate connection such as a flexible, resilient and generally non-rigid tube made of plastic or the like. Disadvantageously, known non-integral connection between the drainpipe and the faucet pipe presents some problems of cleaning and durability.  
           [0005]    Also, in known hot beverage dispensers, the faucet is connected to the outwardly extending, horizontal, faucet pipe by means of a faucet inlet pipe within which is received the faucet pipe and secured by means of mechanical fasteners. The mechanical fasteners, such as bolts or screws, require tools, sometimes special tools to unfasten the faucet from the faucet pipe, as is needed from time to time for purposes of cleaning. Periodic cleaning easy cleaning of the faucet, the faucet pipe, the drain pipe, the U-shaped connecting tube, the interior of the hollow body and the outer surface of the housing supporting and enclosing the hollow, and generally insulated body, is necessary for health purposes. Unfortunately, because of the difficulty of removing the faucet from the faucet pipe this is done less frequently than may be desired. The drainpipe and the faucet pipe are cleaned by using hot water and manually brushing the inside surface of the pipes. While the pipes are relatively impervious to this mechanical brushing, the U-shape tube can be struck with the end of the brush and damaged. Generally, the U-shaped tube is prone to wear and deterioration while the stainless steel tubes are not.  
         SUMMARY OF THE INVENTION  
         [0006]    In accordance with the beverage dispenser and method of the present invention the aforementioned problems and disadvantages of the known beverage dispensers.  
           [0007]    This is achieved in part by providing in a hot beverage dispenser having a hollow body having a top, bottom, an enveloping side wall extending between the top and the bottom and a base for supporting the bottom above a support surface with a manually removable faucet assembly having an outlet pipe connected to the bottom of the hollow body and having a generally horizontal section that extends outwardly from the enveloping side, a faucet with a faucet shank for mating overlapping connection with the horizontal section, a faucet latch member carried by the faucet shank, and a mating outlet pipe latch assembly for releasable latching engagement with the faucet latch member to releaseably lock the faucet shank to the outlet pipe.  
           [0008]    Preferably, the entire outlet pipe is entirely made of stainless steel or other like metal, and has a generally vertical section connected to the bottom of the hollow body, and an elbow section interconnecting the generally vertical section with the horizontal section. The vertical section, the elbow section and the horizontal section are integrally formed together from a single piece of metal pipe. The faucet shank includes an annular slot facing outwardly from a free end of the faucet shank joined to an inwardly facing cylindrical slot communicating between an interior end portion of the annular slot and the interior of the faucet shank, and an 0-ring fitted within the outwardly facing annular slot and partially extending inwardly into the interior of the faucet shank for sealing engagement with the outlet pipe when received within the faucet shank.  
           [0009]    Preferably, the blocking member has a radially outwardly facing rotary latch receiving slot, and the latch member has a radially inwardly facing rotary latch connector for sliding mating receipt within the rotary latch receiving slot. A rotary latch connector has a pair of resilient, radially extending, generally parallel latch fingers with free ends having cam surfaces for engagement with opposite sides of a rotary latch receiving slot to push the fingers together during insertion into the rotary latch receiving slot.  
           [0010]    The objective is also achieved with respect to the known faucet guard assemblies by providing a beverage dispenser of hot beverage with a hollow body having a top, bottom, an enveloping side wall extending between the top and the bottom and a base for supporting the bottom above a support surface, with a faucet assembly having an outlet pipe connected to the bottom of the hollow body and having a generally horizontal section that extends outwardly from the enveloping side, a faucet with a faucet shank for connection with the horizontal section and a nozzle with a distal downwardly facing opening, a faucet guard with a generally horizontal section secured to the bottom with an opening horizontally aligned with the distal downwardly facing opening and having a lowermost guard surface located at or beneath the distal downwardly facing opening to prevent snagging of the faucet nozzle from beneath the nozzle, and an upturned section in front of the faucet. Preferably, the upturned section is transparent.  
           [0011]    This objective is also achieved by providing a beverage dispenser with a hollow body having a top, bottom, an enveloping side wall extending between the top and the bottom and a base for supporting the bottom above a support surface with an outlet pipe connected to the bottom of the hollow body and having a generally horizontal section that extends outwardly from the enveloping side, a faucet with a faucet shank for connection with the horizontal section and a nozzle with a distal downwardly facing opening, a faucet guard with a generally horizontal section secured to the bottom with an opening horizontally aligned with the distal downwardly facing opening and having a lowermost guard surface and an upturned section in front of the faucet that is at least partly transparent to enable viewing of the nozzle adjacent the distal downwardly facing opening. Preferably, the upturned section has means for mounting of a label carrying member.  
           [0012]    In one form of the faucet guard, instead of being made from transparent material, is made of interconnected elongate frame members shaped in the configuration of a guard and the nozzle end is visible through the space between the members. A horizontal section of the faucet guard is defined by a plurality of the elongate members arranged in a plane and the lowermost surface is defined by the plane defined by lowermost surfaces of the elongate members defining the horizontal section are located beneath the lowermost surface of the faucet nozzle. The faucet guard also preferably includes an upturned section in front of the faucet with a cross bar member supported by two generally vertical members. The cross bar member and the two generally vertical supporting members define a plane that is tilted inwardly toward the faucet to facilitate viewing of the bottom of the nozzle underneath the cross bar member and between the two generally vertical supporting members.

     DETAILED DESCRIPTION  
       [0032]    Referring to FIGS.  1 - 4 , the beverage dispenser  20  of the present invention is seen to include a hollow, cylindrical body  22  with a top cover  24 , a bottom  26 , a base assembly  28  for supporting the body  22  with the bottom elevated a support surface  30 , such as the top of a counter or serving cart. The base assembly  28  has a vertical section  32  extending between a forwardly extending horizontal section  34 . The cover has an inlet opening  36  through which the beverage, such as hot coffee, may be directly passed into the interior of the hollow body  22 . A grate  38  of a drip tray assembly  40  is supported by the horizontal section  34  in a position directly beneath a faucet assembly  42 .  
         [0033]    The faucet assembly  42  has a pivotally mounted actuation handle  44 , attached to the top of a faucet body  46  containing a valve (not shown) operated by the handle  44  that interconnects a hollow inlet faucet shank  48  with a inlet shank with a faucet outlet nozzle  50 . The faucet handle  44 , the faucet body  46 , the valve contained within the faucet body  46 , the outlet nozzle  50  may be conventional and the details with respect to these parts, their assemblage into an operative faucet and how the faucet operates form not part of the invention. Briefly, when the faucet handle  44  is in an upright, non-tilted position as shown in solid line in FIG. 2, the valve is closed, and no beverage passes through the valve from the hollow inlet shank  48  to the outlet nozzle  50 . A spring (not shown) located within the body  46  resiliently biases the valve to automatically move this closed position when not being manually held in the open position. When the handle  44  is pivoted in the direction of arrow  52  to the position  44 ′ shown in broken line in FIG. 3, the valve is open and beverage within the hollow body is passed through the inlet shank  48 , the valve and out of the outlet nozzle  50  and into a suitable container for serving.  
         [0034]    Referring also to FIGS. 4 and 5, what is new about the faucet assembly  42  of the present invention and described in detail below includes a special end configuration of the inlet shank  48 , a special end configuration of the outlet pipe that interconnects the interior of the hollow body  22  with the inlet shank  48  and a quick release latching and mounting mechanism and method that operate in cooperation with the special end configuration of the shank  48  and of the outlet pipe that enable the remainder of the faucet assembly  42  to be easily removed manually and to be manually mounted manually without the use of any tools. Such quick removal enhances the ability to clean the faucet assembly  42 , itself, and to clean the interior of the dispenser outlet pipe  52  from the outside of the hollow body  22  with a brush or the like inserted into the outlet end  54  of the outlet pipe  52 .  
         [0035]    Achieving one aspect of the invention and in keeping with another aspect of the invention, the dispense outlet pipe  52  is made of a single piece of metal, preferably stainless steel, with no non-metal parts. In particular, the there is no fragile connecting joint made of silcon tube stock or the like at the ninety-degree turn between the horizontal run  56  and the vertical run  58  of the outlet pipe  48  to further facilitate cleaning without risk of damage to the dispense outlet pipe  48 . The ninety-degree turn  60  is formed by a piece of the outlet pipe  52  that is integrally formed together with the vertical run  58  and the horizontal run  56 . Preferably, the entire outlet pipe  48  is formed of a single piece of stainless steel tube stock that has been turned and cut to size and then machined and flanged.  
         [0036]    The inlet end of the dispense pipe  52  is flared to receive another stainless steel connector  62  that interconnects the dispense pipe  52  with the drain hole  64  at the bottom  66  of an insulated liner  68  supported within the hollow body  22  above the bottom  26  to provide space for passage of the dispense pipe. The outlet end of the dispense pipe  52  is especially adapted, or configured, with an inwardly tapered bezel  70  on its outside surface to facilitate easy insertion into the hollow inlet shank  48 . The horizontal run  56  of the dispense pipe  48  passes through a sealed opening  72  and has a outward extent  74  that substantially extends beyond the front of the hollow body  22  by preferably no less than an inch at a position adjacent the bottom  26 . The faucet assembly  42  is thereby cantilever mounted to the front surface  76  of the hollow body  22 .  
         [0037]    Referring now also to FIGS. 6 and 7, at the inlet end of the hollow inlet shank  48  of the faucet assembly  42  is a rotary interleaving, female, rotary latch member  78 . The female latch member  78  is preferably integrally formed at the free, open end of the hollow cylindrical body of the inlet shank  48 , and has a generally half annular shape with a latch receipt notch  80  that opens outwardly in a radial direction from the middle of the body of the female latch member  78 . The ends  79  and  81  of the female latch member  78  are beveled to form a cam surface to push against the bottom  91  of the slide plate  94  of the latch assembly  92 . If the slide plate is in a lowered position, when the faucet shank and the female latch member are rotated 180-degrees the force of the cam surface against the bottom will push the slide plate out of the path of the female latch member so it can reach the top position at which it may be locked against rotation out of the locked position shown in FIG. 5.  
         [0038]    The end of the inlet shank is also specially adapted with an O-ring seal assembly including a resilient O-ring  82  received within a cylindrical slot  84  in the open end of the inlet shank  48 . An annular slot  86  at the inside of the inlet shank  48  communicates with the cylindrical slot  84 , and the O-ring  82  is seated in the annular slot  86  and slightly protrudes into the interior of the inlet shank  48  to engage and seal the outside surface of the outwardly extending portion  74  of the horizontal run  56  of the outlet tube  52  with the interior surface of inlet shank  48 . The inwardly beveled surface  70  at the outlet end of the outlet pipe  52  facilitates easy insertion of the outlet end into the inlet shank  48  and prevents the end of the outlet pipe  52  from hitting the side of the O-ring  82  and dislodging or damaging the O-ring  82 . Instead, the beveled end slips within the O-ring  82  without touching it and then gradually engages the O-ring  82  in a radially outward direction as the outlet pipe  52  is slid further into the shank  48  and the portion of the outlet pipe  52  within the O-ring gradually changes from the inwardly located surface of the beveled end  70  to the fully O-ring engaged cylindrical surface of the outlet pipe  52 , when fully inserted, as shown in FIG. 5. After the O-ring is installed and seated within the annular slot  86 , a retainer  88  is inserted into the end of the cylindrical slot  84  to keep the O-ring in place, seated within the annular slot  86 .  
         [0039]    Referring to FIGS. 8, 9 and  10 , the front of the body  22  carries a fixed latch member  90  overlying the upper part of the outlet pipe  52  and a slide latch assembly  92 . Referring to FIGS. 11, 12 and  13 , the slide latch assembly  92  has a slide plate  94  with an elongate slot for receipt of the outlet pipe  52  and the shank  48 . As also seen in FIG. 5, the back  96  of the slide plate  94  is located adjacent the front of the hollow body  22 . Located in front of the front  98  of the slide plate  94  is a male latch assembly  100 . The mail latch assembly has a pair of spaced resilient, downwardly extending fingers  102  and  104 . At the free ends of the fingers  102  and  104  and outwardly extending latch members  106  and  108 , respectively. At the outer sides of the latch members  106  and  108  are canted cam surfaces  110  and  112 . During installation of the faucet assembly  42 , the shank  48  is slipped onto the forward extent  74  of the outlet pipe  22  with the top of the handle  44  at the bottom. In this inverted position, the female latch member  78  is enabled to pass beneath the fixed latch member  90 . Upon engagement with the bottom  114  of the slide plate  94 , the faucet is rotated 180-degrees to rotate the female latch member  90  into a position between the aft surface of the fixed latch member  90  and the forward surface of the slide plate  92 . When the latch receipt slot  90  is directly beneath the free ends of the fingers  102  and  104 , the slide latch is lowered until the latch members  106  and  108  are fully engaged within the latch receipt slot  90 . The latch receipt slot  90  has outwardly extending pockets  111  and  113  within which are snugly received the outwardly extending latch members  106  and  108  when fully latched. When the slide latch  92  is lowered, the canted cam surfaces  111  and  113  are engaged by the opposite sides of the inlet  115  to the latch receipt notch  80 , and the fingers  102  and  104  are thereby squeezed together until the peaks  114  and  116  of cam surfaces pass the inlet  115  and the fingers  102  and  104  resiliently snap outwardly with the latch members  106  and  108  snugly received within the outwardly extending pockets  111  and  113 . When fully latched, the faucet assembly  42  is prevented from rotating away from the fully upright, operating position to an inverted, removal position in which its removal is not blocked by engagement of the fixed latch member  90  with the female latch member  78 . The latched position is shown in FIG. 9 and the unlatched position is shown in FIG. 10.  
         [0040]    In order to unlatch the faucet assembly  42 , the slide plate is pushed upwardly from the bottom  118  and the cam surfaces  120  and  130  above the peaks  114  and  116  squeeze together the fingers  102  and  104  until the peaks  102  and  104  upwardly pass through the inlet of the notch  80 . The fingers then return to their non-stressed position shown in FIG. 11 and are again ready for latching by downward movement of the slide plate by pressing downwardly on the top  120  of the slide plate. The slide plate is pushed upwards by the cam surfaces at the ends of the female latch member during rotation of the female latch member to the latch position.  
         [0041]    Referring now to FIGS. 14 and 15, another object of the invention is achieved by providing a faucet guard assembly  52 . Unlike known faucet guards, all or a portion of the faucet guard is transparent to enable better visual access to the bottom of the faucet  42  to help users properly align and locate cups and other containers directly beneath the dispense outlet  50  of the faucet assembly  42 . At least part  122  of an upstanding portion  124  of a generally L-shaped guard member  127  is transparent. In addition, the upstanding portion  124  is slanted upwardly and inwardly from a position substantially forward of the faucet assembly  42  to facilitate viewing of the faucet through the transparent portion of the upstanding portion. An insert for carrying trademark or beverage name or the like is either limited to the uppermost part of the upstanding portion  124 , or the opaque portion is so limited. Preferably, the entire guard member  127  is integrally formed and also made of any suitable material that is not only transparent but also can be used in contact with food and can withstand high temperatures and humidity without deterioration.  
         [0042]    The upper part of the upstanding portion  122  has a detent or hollow section  126  adapted for receipt of U-shaped advertising or beverage name insert  128  in the form of a U-shaped, resilient, snap-on plastic member  130 . If the insert extends down to distal end  131 , then snap on member  130  may also be transparent and may have a transparent background to enable both viewing of the advertising, logos or labels and visual access to the bottom of the faucet  42 . Alternatively, the snap-on member  130 , itself, or the opaque portion of the snap-on member, only extends to location  133  which is sufficiently close to the top  135  of the upstanding portion  122  of the guard assembly to preclude blocking a line of sight through the transparent portion of the bottom  50  of the faucet. Even if the entire member  130  is opaque, visual access is still improved due to the transparent section  132  beneath the member  130  as well as side windows  131  and  133 . If desired, the advertising insert member  130  may be easily removed entirely and the guard member  127  used with the detent  130  for the advertising insert member  130  but without the advertising member  130 , itself. The detent may be eliminated if an advertising insert is not desired, or an advertising insert may be used without a detent or integrated into the guard.  
         [0043]    As best seen in FIG. 5, the faucet guard assembly  42  includes a hand operated threaded fastener  135  that is received within a central, elongate mounting slot  132 . The slot  132  has an opening  134  at the back edge of the horizontal mounting plate  136  opposite from the end to which is attached the upstanding portion  122 . This opening  134  enables removal and position adjustment of the guard member  127  without separating the treaded fastener  135  from the bottom  26 . Preferably, the treaded fastener  135  has an interior blocking member  139  in front of a threaded section to prevent removal of the fastener  135  from the bottom  26  even when no longer in threaded engagement with the screw hole  141  within which it is received. When used to mount the faucet guard assembly  160  of FIGS.  16 - 18 , below, the treaded fastener is received within a corresponding slot  170 .  
         [0044]    Achieving another object of the invention, as best seen in FIG. 5, unlike known guard assemblies, in the faucet guard assembly  60  of the present invention, the guard member  127  is mounted with the bottom of the faucet assembly  42  slightly above the bottom surface  142  of the horizontal guard plate  144 . Preferably, the faucet outlet  50  is located between top surface  143  of the horizontal guard plate  127  and the bottom surface  142  of the horizontal guard plate  144 . With the top surface  143  of the guard plate  144  being above the dispense outlet  50  upward splashing on top of the horizontal guard plate  144  is reduced relative to the circumstance with the outlet  50  being located above the guard. With the bottom surface  142  of the guard assembly  60  being beneath the dispense outlet  50 , the bottom surface  142  prevents inadvertent lateral engagement of a cup or other container with the bottom of the faucet during removal of the cup from beneath the dispense outlet  50 . Such lateral engagement, such as can happen with known guards in which the dispense outlet  50  is not flush with or above the bottom surface but instead extends substantially beneath the bottom surface of the horizontal guard member  144 .  
         [0045]    Referring to FIGS. 16, 17 and  18 , an alternative faucet guard assembly  160  is seen that is formed from a single, solid-core, stainless steel rod that has been bent into the approximate shape of the perimeter of the faucet guard assembly  60 , FIG. 5. The horizontal section is formed of two, parallel, U-shaped rod sections  162  and  164 . Inside portions  166  and  168  define a slot  170  corresponding to the slot  134 , FIG. 14, of the guard assembly  60  and is similarly engaged by the threaded fastener  135  to attach the guard assembly  160  to the bottom  26  of the beverage dispenser  20 . Outer, parallel portions  172  and  174  of the U-shaped members  162  and  164  extend forwardly of the ends  176  and  178  of the inner portions  166  and  168  to provide underlying support for a pair of upstanding sections  180  and  182 . The upstanding sections are interconnected by a horizontal cross section  184  that defines the upper edge of the guard. As seen in FIGS. 16 and 18, the cross member  184  is bowed outwardly. As seen in FIG. 16, the upstanding members  180  and  182  are sloped inwardly toward the faucet  42 . Thus, the perimeter shape and dimensions of the faucet guard  160  is substantially the same as the faucet guard  60  and if fits relative to the faucet in substantially the same way as shown and described with reference to FIGS. 5 and 11- 14 . The plane  175  defined by the lowermost surfaces of the U-shaped sections  162  and  164  is at least slightly above the lowermost portion of the nozzle  50  when the faucet guard is properly mounted. The lowermost portion  50  of the nozzle is also visible from in front of the beverage dispenser  20  through the space beneath the cross section  184  and between the upstanding members  180  and  182 .  
         [0046]    The inward slant of the upstanding members  180  and  182  upstanding sections moves the cross bar  184  closer to the beverage dispenser  20  an out of the way of a clear view of the nozzle end  50 . The cross bar  184 , in addition to guarding the faucet, may serve the additional function of a handle to facilitate manual manipulation of the dispenser during moving of the dispenser.  
         [0047]    While a particular embodiment has been disclosed in detail to illustrate the best mode contemplated of practicing the invention, it should be appreciated that many variations may be made with respect to such details without departing from the scope of the invention as defined in the appended claims.
