DETAILED DESCRIPTION OF THE INVENTION

(14) Referring now to the drawings, wherein like reference numerals designate corresponding structure throughout the views. The following examples are presented to further illustrate and explain the present invention and should not be taken as limiting in any regard.

(15) Referring to FIGS. 1-3, the handle is shown with a narrowed portion 2 which fits through a hole in the grill lid and extension 4 which is of a larger diameter than portion 2. This extension 4 in some embodiments is internally threaded and piece 6 includes a male threaded portion which engages extension 4. In other embodiments, the attachment between piece 4 and 6 is a ratchet system similar to ratcheting wrenches. Friction couplings and friction locks can also be used. In this manner, the handle can be rotated 21 but will stay in the desired position to which it is rotated. Further detail of one exemplary locking/rotation mechanism is depicted in FIGS. 7-12.

(16) Curved connector/elbow 8 provides for a 90 degree angle between portion 4 and extension tube/housing 12. This angle may vary depending on how the grill lid is configured in that when the grill lid is opened, the extension tube 12 should generally be horizontal when rotated 21 to extend towards the user with the hollow end 16 of the tube facing outwards (See FIG. 6). The axis of rotation of the handle can be adjusted so that if, e.g. the angle of the attachment point of the lid surface relative to the grill surface is not parallel that the joint rotation can be offset so that the handle is generally parallel the attachment point's surrounding surface and so that when the lid is open the handle is generally parallel to the cooking surface. This ensures that the light shines directly down on the grill/cooking surface. Generally therefore, in the use position the handle's longitudinal axis will be perpendicular to the hinge axis for the lid—the hinge axis being the axis about which the lid rotates which is generally shown where the grill and lid meet in FIG. 6. It is also contemplated that the lens of the light source can be adjusted/calibrated to direct light to cover the cooking surface and to account for lid shapes and configurations/orientations in the open position relative to the cooking surface.

(17) Section 10 connects the piece 6 with the male threaded portion to the extension tube. This extension tube has a cutout 14 with edges 17 and 15 sized to receive a light therein. The location of edge 15 and the length of the extension tube 12 and section 10 is designed such that the light path or cone the light creates is not interfered with by the grill lid. Specifically, the center of the hole in which the narrowed portion 2 is mounted in a hole which is spaced apart from the bottom edge of the grill lid at a given distance. The light cone will extend generally in an outwardly tapered direction from edge 15 towards narrowed portion 2. Given the height of the light source over the outside of the grill edge and the location of the mounting hole for the handle, the edge can be located to hold the light far enough away from the bottom edge of the grill lid so that the light cone is not interfered with in the orientation shown at FIG. 6.

(18) As can be seen extension tube 12 is hollow 16. Furthermore, piece 10 can also be a screw/ratchet or other rotation system to allow rotation similar to rotation 21 but in this case the handle would twist 190. This twisting action can be used to direct the light left to right on the grill. Thus, the handle can rotate 190/21 about two axes. This allows the handle to be positioned to move up/down to open/close the lid and then once open, the handle can be positioned to extend outwardly so that the opening 14 points downwards. Then, the handle can be manipulated to direct the light cone left or right or centered to illuminate the desired area. Preferably, the light cone is large enough to illuminate the entire surface of the grill without need for the left to right rotation.

(19) FIG. 4A-B shows the light which inserts into hollow end 16 where the lens can emit light out opening 14. The light lens 18 is an amplifying reflector lens with a series of LED lights behind it. The body/housing 20 of the light is cylindrical and hollow and can receive standard sized batteries such as AA or AAA batteries. End 22 screws on/off in order to replace batteries as needed. At the opposite end, button 39 is used to turn the light on/off. The light lens 18 and LEDs are mounted in boss 11 which extends from the body and as shown is generally rectilinear in shape or includes at least two parallel sides which fit within edges 17. The base of the boss 11 (where lead line for boss 11 ends) will abut edge 15 to limit insertion of the light. The light may be provided with a voltage amplifier circuit to increase the voltage supplied by the batteries to the LED. Optionally, the end 16 of the extension tube 12 may include threads or another attachment system to place a retaining piece on the end to inhibit the light from falling out. As shown in FIG. 5, the handle is installed on the grill and decorative wrap 26 is added to the handle. The decorative wrap may be leather, wood, ceramic, plastics or other materials. The extension tube 12 may be made of a material both decorative and structural such as stainless steel, carbon fiber and others. The button 39 in this case would be accessible by someone taking their left hand to hold the handle and pressing the button with their thumb to activate the light.

(20) In certain cases, the handle is provided to be easily removable and replaceable with differently decorated handles. In some cases, the light is not provided in the handle and the cutout 14 is also not provided. In this case, the handle as shown is a single point mount which can rotate for e.g. left or right hand operation. The handle may also be provided to rotate into position and then be locked there. The single point mount allows the handle mounting position to be easily varied among different size/shape grills and with different orientations of the handle.

(21) Optionally the end 22 diameter and body 20 diameter are the same and are sized to match or be slightly smaller than the inner diameter of the extension tube 12 so that the light is insertable and held securely in the extension tube 12. The end 22 may include a magnet and the inside of the handle may include a magnetic receptive material that the magnet in end 22 holds to with magnetic force.

(22) Once the handle has been used to open the grill lid as shown in FIG. 6 (or as that opening occurs), the handle can be rotated 21 so that the button 39 is generally facing the user. The handle can then be twisted 190 to change the position of the light cone 230 relative to the grill surface in generally the left and right directions. Preferably, the light pointing straight down provides a light cone which captures the entire grill surface. Optionally, the light can be twisted 190 to illuminate the controls for the grill. The light cone 230 may also be wide enough to illuminate the grill surface and controls which are outside the grill surface. It is understood that this handle can be utilized in other cooking appliances or situations where lids are manipulated by handles and then also could benefit from illumination such cooktops, storage boxes and other lid covered items, particularly those designed to be kept outside.

(23) FIGS. 7-11 show additional detail concerning the construction of the handle. Particularly, the handle may include a decorative base 307 which attaches to the grill lid with two screws 23 which include lock washers 25 to inhibit the handle and lid connection from becoming loose over time. A bracket 3 mounts in this decorative base 307 and a screw 9 connects this bracket 3 to the decorative base 307. As shown, the bracket is generally a U shaped channel with two holes for screws 23 and holes for screw 9. A screw 19 with a shoulder shown at the lower end near the screw head is positioned in the base 307 and connects to the elbow 8 to provide the rotating joint about the axis of the screw. As shown in FIG. 12, on either sides of screw 19 and spaced from the screw/rotation axis of the handle are springs 150 which press against ball bearings 37. These ball bearings can move up and down into and out of detents 41 which are placed normally to create resistance in the stored (FIG. 5) and the activated/use (FIG. 6) positions. In this way, when the detents are reached, the balls 37 enter the detents and provide resistance against rotation about the axis of screw 19. This provides stops for the handle in two positions, stored and use (grill surface is illuminated). The resistance to rotation between detent(s) is less relative to the resistance to rotation with detent (s) engaged. Specifically, a race may be provided for the ball bearing to move relatively smoothly between stored and use positions but the detent is at a level spaced from the race along the rotation axis of the handle and the springs 150 will move the ball into the detent and thus increase the rotation resistance. It is understood that “activated” or “use” positions of the handle refers to those intended for the light to be useful in illuminating the grill/cooking surface and that in the “stored” position, the handle is still useful to open/close the grill lid. Generally, the stored position will be roughly parallel to the grill surface when the lid is closed and the activated or use position of the handle is preferably at 90 degrees to the stored position or 90 degrees to the bottom edge of the lid to a plane defined by the bottom edge of the lid.

(24) Screw 19 includes washers 35/31—typically nylon but other materials are contemplated. Spring 33 is provided to allow the elbow to move slightly axially to accommodate the balls 37 moving into and out of the detents 41. In this way when the handle is in the stored position FIG. 5, there will be adequate resistance that if the user pulls up on the handle to open the lid, the handle will not rotate. If the user pushes down on the handle to close the lid, the handle will also not rotate. However, if the user wants to rotate the handle, they can do so by e.g. applying force to housing 12 to enable the balls 37 to be forced out of the detents and into a channel, thus releasing the pressure keeping the handle from rotating. Then, the user rotates until the set of detents aligned with the use/activated position (FIG. 6) engage the balls 37, thereby holding the handle so that the end of the handle is generally facing outwards towards the user (FIG. 6). This action also helps to keep the light in a steady position when in use for viewing food on the grill. FIG. 11 also shows a set screw 5 which engages screw 19 to inhibit/prevent the screw 19 from coming undone from the threading in elbow 8. As can be seen, the set screw 5 can be accessed through the housing 12 when the light 240 is removed e.g. by unscrewing the end cap 1. Alternately, this screw 19 can be accessed by removing screw 27 and allowing the housing 12 to be removed from the elbow 8. The switch (shown as a push button) is accessible via a hole in the end cap 1 thereby providing for a smooth rotation operation of the handle from stored position (FIG. 5) to the lighted position (FIG. 6). A ball 37 and detent 41 may include electrical contacts which close a circuit when the ball is in the detent by touching the spaced contacts. This can operate as a switch to turn the light source on when the handle is in the use position.

(25) As can be seen the spacing between the edge 15 of the light source opening closest to the attachment point and the axis defined by screw 19 is located so that when the handle moves to the use position that the edge 15 hangs out over the grill surface beyond the bottom edge of the grill lid. This is also dependent on the location of the attachment point relative to the bottom edge of the grill lid. Preferably, the spacing is such that the light cone 230 does not hit the grill lid. Particularly, the distance measured It is noted that the light cone in FIG. 6 is shown side to side but that it is understood that the light cone also has a fore/aft component whose angle and projection pattern depends on the light source and lens configuration used therein.

(26) Although the invention has been described with reference to a particular arrangement of parts, features and the like, these are not intended to exhaust all possible arrangements or features, and indeed many other modifications and variations will be ascertainable to those of skill in the art.
