FIELD OF THE INVENTION
Drip trays and drip tray assemblies, more specifically, a drip tray assembly for engagement with a drain line for removing fluid accumulating in the drip tray.
BACKGROUND OF THE INVENTION
Drip trays function to both support a container on an upper surface thereof and to receive spilled beverages from a beverage dispenser. Drip trays need to be cleaned from time to time. Drip trays also may need to drain accumulated fluid therein so as to maintain a sanitary condition.
SUMMARY OF THE INVENTION
A drip tray and base assembly for a beverage dispensing urn is provided comprising an urn housing, a base for supporting the urn housing thereon in spaced apart relation to a support surface. The base includes a faceplate, the faceplate has a faceplate cutout. The faceplate cutouts having faceplate cutout walls. A drip tray is provided, the drip tray having a perimeter portion and a ribbed, grate-like top surface. The drip tray has a floor and a drain extension. A coupling member is configured to removably, toollessly engage the face plate cutout walls. The coupling member has inner walls defining a drain channel, the drain channel having a near and a removed end. The wall defining a drain channel is dimensioned for snug fluid tight, toolless coupling with the drain extension of the drip tray at the near end thereof. The drain channel has exterior walls at a removed end thereof, the exterior walls being dimensioned for snug receipt into the removed end of the drain line.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
FIGS. 1 and 1A illustrate a drip tray assembly comprising a drip tray 26 and a coupling member 28. The drip tray assembly will engage a base 22 of an urn 10. The urn 10 typically has an urn housing 12 with beverage dispensing valves 14 engaged therewith. Beverage dispensing valves 14 are disposed with nozzles above the drip tray. The drip tray 26 functions to support a beverage container (not shown) thereon and typically includes a top grate 58 having a multiplicity of ribs 60 thereon for allowing fluid to drain into the interior thereof. The interior of the drip tray 26 may be comprised of a floor 62, which may be integral with an upstanding perimeter wall 50 and an upstanding facing plate 52. Perimeter wall 50, facing plate 52, and floor 62 define an interior space that may contain a fluid.
Applicant's drain tray 26 may be integral, that is, the top grate 58 being molded into other elements of the drip tray so it is not removable. In an alternate preferred embodiment, as seen in FIG. 5, top grate 58 is removable, so as to provide access to the interior of the drain for cleaning out fluids accumulating therein. When the drip tray 26 is integral, that is, the top grate 58 is not removable, the drip tray should be removed from the remainder of the urn for washing, for example, in a dishwasher.
Turning to the general construction of urn 10 in FIGS. 1 and 1A, it is seen that urn 10 may include a housing engagement conduit for engaging the valve or valves to the housing so they are in a spaced apart relation and above the drip tray. A handle 18 may be provided for dispensing a fluid from dispensing nozzle 20 of the one or more valves 14. Housing 12 may rest upon a base 22 that may include housing engagement members 24 for engaging a lower rim of the housing, the base for itself resting upon a support surface, such as a tabletop or other suitable support surface. Housing engagement members 24 are typically configured in ways known in the art to provide stability to the urn housing.
Applicant provides drip tray 26 and coupling member 28 to toollessly couple with one another in a fluid tight manner, so as to carry fluids accumulating in the drip tray away to a drain line 29 (see FIG. 2). A second function of the coupling member 28 is to assist in locating the drip tray adjacent the base, in a use position below the valves. Part of the base 22 may include a forward located, upstanding faceplate 30, which may be recessed back from a front rim 38 defining a forward edge of the base. The base 22 may have a top wall 36 and side walls 32/34. In addition, as seen in FIGS. 1, 4, and 4A, there may be lateral locating tabs 40/42 projecting forward from the front of the base to engage slots 51/55 of the drip tray to provide location and lateral stability to the drip tray when it is engaged to coupling member 28 and base 22 in a manner set forth in more detail below. Such coupling of tabs to slots is a direct coupling of the drip tray to the base.
Base 22 is seen to have a faceplate 30 having a cutout 44 that may be centrally located or located at any other suitable place along the faceplate. Cutout 44 is defined by cutout walls 46 and may be open to lower edge 48 of faceplate 30.
Turning now to drip tray 26, perimeter walls 50 are provided as well as a facing plate 52, which is dimensioned to lay substantially flush with faceplate 30 when drip tray 26 is coupled to coupling member 28, and coupling member 28 is coupled to cutout walls 46 and tabs 40/42 are located in slots 51/56 (as seen in FIGS. 1, 4, and 4A). Such a position is a “use position” placing the drip tray in a proper use position beneath the valves as seen in FIG. 1B. Note in FIG. 2, that perimeter walls 50 may be comprised of inner and outer segments, with the inner segment integral to floor 62.
Facing plate 52 may include lateral shoulders 54/56 that, along with the slots 51/55 and the removed ends 50a/50b of the perimeter walls 50 will help make a secure, stable toolless and fluid tight engagement of the tray to the base when the tray is in the use position (see FIG. 1B).
Turning now to the manner in which the fluid tight coupling occurs, it may be seen that a drain extension 64 extends forward or outward from facing plate 52 as seen in FIGS. 1, 1A, 2, 2A, and 3. Indeed, it is seen that drain extension 64 includes a channel 65 therein. Moreover, floor 62 slopes downward toward the drain extension 64 (usually the lowest point), so that it is able to collect the fluid (see FIG. 2).
Turning now to FIGS. 11A, 1B, 2, and 2A, it is seen that both the structure and function of the drip tray/coupling member/drain base/drain tube may be appreciated. Those units join together structurally in the manner illustrated to drain fluid accumulating on the floor of the drip tray 26 through to drain tube 29 in a manner that allows the drip tray to be toollessly and easily removed from the base for cleaning. It is seen, for example, with reference to FIG. 2A, that cutout walls 46 of the base may couple with coupling groove 72 of the coupling member, such that base 74 of coupling member 28 is prevented from moving fore and aft or side to side by engagement with coupling groove 72 and walls cutout 46 in the manner illustrated. It may also be seen that a lower edge of base 74 is aligned with lower edge 48 of faceplate 30, so both are supported by a support surface, such as a tabletop. Moreover, it is seen with reference, for example, in FIGS. 2 and 2A, how drain extension 64 is located at the low spot in the floor, the channel 65, which is low enough to pick up accumulated fluid from a sloped floor will plug into extension member 76 of coupling member 28. Base 74 of coupling member 28 includes a face wall 71 that is flush with facing plate 52 and aligned with and in a common plane with recessed faceplate 30.
Turning back to FIGS. 2 and 2A, it is seen that, due to the locating effect of coupling 46/72, removal as by pulling the drip tray out along the axis of drain extension 64 and extension member 76 will allow O-rings 68 located in groove 66 to maintain a fluid tight coupling until they pass out of the extension member. Moreover, it is seen that channel 65 of drain extension 64 and drain channel 77 of coupler 28 have a common longitudinal axis. Moreover, extension member 76 has a near end 80 for snugly and telescopically receiving as a female the male drain extension 64 of tray 26. This coupling indirectly engages the drip tray to the base, through the coupling member. In an alternate embodiment, coupling member is integral to faceplate 30. Removed end 78 of extension member 76 is dimensioned for receipt as a male into female end of drain tube 29, as seen in FIG. 2, for example, and a clamp 82 may cinch the drain tube 29 to the outer walls of the removed end 78.
Although the invention has been described in connection with the preferred embodiment, it is not intended to limit the invention's particular form set forth, but on the contrary, it is intended to cover such alterations, modifications, and equivalences that may be included in the spirit and scope of the invention as defined by the appended claims.
