## Background
FIELD OF THE INVENTION
The present invention relates to cooking appliances and, more particularly, to a siding drip tray assembly for a cooking appliance.
BACKGROUND OF THE INVENTION
Cooking appliances, and in particular electric grilling devices such as griddles, are known. These grilling/griddle devices typically have a lower housing having a lower cooking surface and an upper housing having an upper cooking surface, wherein the cooking surfaces are typically heated by an electrical resistance heater. A handle attached to the upper housing allows a user to raise and lower the upper housing relative to the lower housing to accommodate a food item therebetween to be heated.
While existing grilling devices are generally suitable for what is regarded as ordinary performance, there is room for improvement in terms of cleanliness and convenience. As will be readily appreciated, while existing grills may include a drip tray that is manually positionable to collect drippings or run off of cooking juices from the front of the lower cooking surface, drippings from the upper grill surface can create an undesirable mess. In particular, especially when in the partially open position or fully open position, the run off of cooking juices from the rear edge of the upper cooking surface typically is not collected and instead finds its way to a countertop or other surface on which the grill is placed.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 1-5, a cooking appliance 10 according to an embodiment of the present invention is shown. As shown therein, the cooking appliance 10 generally takes the form of a countertop grill and includes a lower housing 12 having a lower cooking plate 14 and an upper housing 16 having an upper cooking plate 18. The upper housing 16 is operatively connected to the lower housing 12 via opposed frame members 20 extending from the lower housing 16. In particular, as shown therein, the upper housing 16 rides in a guide track 22 in the frame members 20. A handle 24 attached to the upper housing 16 allows a user to raise and lower the upper housing in the guide track in order to selectively position the grill 10 in a closed position, as shown in FIG. 3, a partially open position, as shown in FIG. 4, and a fully open position, as shown in FIG. 5.
As best shown in FIG. 5, the cooking plates 14, 18 have sidewalls that function to retain the run off of cooking juices when in a generally horizontal position (i.e., when in the closed/cooking position shown in FIG. 3 or the fully open position shown in FIG. 5).
With particular reference to FIGS. 3, 4 and 5, the grill 10 also includes a drip tray 26 slidably received in a rear of the lower housing 12. As shown therein, the drip tray 26 is configured to automatically extend from the lower housing 12, in the direction of arrow A, when the handle 24 is raised so as to catch any run off of cooking juices from the upper cooking plate 18. Similarly, the drip tray 26 is configured to retract into the lower housing 12 when the handle 24 is lowered. Importantly, the drip tray 26 is configured to automatically extend from the lower housing 12 to catch the run off of cooking juices when the grill is in the partially open position, as shown in FIG. 4.
The drip tray 26 is automatically extendable and retractable from the lower housing 12 upon raising and lowering of the handle 24, respectively, via a pulley mechanism 28. As shown in FIGS. 6 and 7, the pulley mechanism 28 includes pulleys 30, 32 at opposed distal ends of the handle 24. A wire 34 extends from one of the pulleys 30, 32, past a series of smaller pulleys 36, and to the other of the pulleys 30, 32. The distal ends of the wire 34 are releasably secured to each of the pulleys 30, 32 to effect extension and retraction of the drop tray 26, as discussed hereinafter. At an approximate midpoint along the length of the wire 34, a generally rectangular slide 38 is fixedly secured to the wire 34.
With reference to FIG. 8, the drip tray 26 is generally rectangular in shape and includes a pair of tabs 40 having an aperture therethrough formed on the bottom of the drip tray 26. As best shown in the enlarged illustration of FIG. 9, the slide 38 is retained between the tabs 40 and the wire 34 is provided through the apertures in the tabs 40, which integrates the drip tray 26 with the pulley mechanism 28.
In operation, as the handle 24 is lifted from the closed position of FIG. 3 towards the intermediate/partially open position of FIG. 4, the pulley 32 releases the wire 34 such that it may be unrolled therefrom, while pulley 30 rolls the wire up. As shown in FIG. 7, this causes movement of the wire in the direction of the arrows, and causes the slide 38 to move therewith. As the slide 38 is fixed between the tabs 40 on the bottom of the drip tray 26, the drip tray 26 moves with the slide 38. As such, as the handle 24 is lifted, the movement of wire 34, and the slide 38 pushes the drip tray 26 out of the lower housing 12 to its extended position, where it serves to catch run off of cooking juices from the upper cooking plate 18.
Conversely, when the handle 24 is lowered towards the closed position of FIG. 3, pulley 30 releases the wire 34 such that it may be unrolled therefrom, while pulley 32 rolls the wire up. As will be readily appreciated, this causes the wire 34, and thus the slide 38, to travel in the opposite direction, thereby pulling the drip tray 26 into the lower housing 12.
As disclosed above, the drip tray 26 is automatically extendable from the lower housing 12 when the grill 10 is opened, thereby obviating the need for a user to clean the countertop after use or to manually position a drip tray to catch cooking juice run off. Likewise, the drip tray 26 automatically retracts into the lower housing 12 when the grill is closed, for compact storage. Accordingly, the grill of the present invention provides a degree of convenience and cleanliness heretofore not seen in the art.
Although this invention has been shown and described with respect to the detailed embodiments thereof, it will be understood by those of skill in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed in the above detailed description, but that the invention will include all embodiments falling within the scope of this disclosure.
