Abstract
A positioning lever for use with a rotisserie cradle of the type wherein clamping rods may be angularly and radially disposed for the containment of food therein by means of rotational adjustment of two pairs of slotted plates disposed at either end thereof. The positioning lever allows the clamping rods to be quickly and easily repositioned.
Claims5
In a rotisserie grill of the type comprising a cradle for supporting food to be cooked, said cradle having:
- first and second opposite end plates connected together and shaft means mounted to said plates, with a free end extending longitudinally outwardly therefrom, said end plates each having a plurality of radially disposed slots and means forming an aperture adjacent the periphery thereof;
- first and second control plates rotatably mounted on the shaft means associated with, respectively, said first and second end plates between said first and second end plates and said free ends of the shafts, said first and second control plates each having a plurality of spiral shaped slots;
- a plurality of longitudinally disposed clamping rods, each rod extending through one radial slot in each plate and one spiral slot in each control plate and movable within said slots as said plates are rotated with respect to each other such that the radial and angular position of said clamping rods with respect to the axis of rotation of each of said shafts may be selectively and independently varied across the length of the cradle;
- and
- means forming a plurality of spaced apertures adjacent the periphery of the first and second end plates and alignable with the apertures in the first and second control plates;
- wherein the improvement comprises a positioning lever disposed on an outer surface of each control plate, the positioning lever including:
- a housing including a top, opposed side walls, a first open end, and a second closed end to define a slot therein, the first end being disposed over the aperture in the control plate and the second end extending radially inwardly toward the shaft means;
- a biasing means disposed in the slot having first and second ends, the first end being attached to the housing;
- a pin formed on the second end of the biasing means and capable of moving from a first position, wherein it extends through the aperture in the control plate and a first one of the plurality of apertures in the end plate which has been aligned therewith, to a second position wherein the pin extends through the aperture in the control plate, said pin being biased into the first position;
- and
- a lever having first and second ends, the first end being slidably disposed in the slot between the biasing means and the control plate, and the second end extending from the housing, said lever having an extension formed on the first end extending toward the biasing means,
- wherein the radial and angular position of the clamping rods may be adjusted by first applying radial force in an outward direction to the second end of the lever, thereby causing the lever to be slidably disposed at least part way out of the slt and to bias the biasing means so as to urge the pin to move into the second position, and then applying rotational force to the second end of the lever to rotate the control plate with respect to the end plate and align the aperture in the control plate with a second one of the apertures in the end plate, thereby causing the plurality of longitudinally disposed clamping rods to be set at a preselected position, the preselected position being fixed by slidably displacing the lever back into the housing and allowing the pin to move back into the first position, whereby it extends through the aperture in the control plate and the second one of the plurality of apertures in the end plate.
