## Background
FIELD OF THE INVENTION
The present invention relates to cabinets for holding trays, and, more particularly, is concerned with a multi-tray cabinet with a compound opening.
BACKGROUND OF THE INVENTION
Multi-tray cabinets (also referred to as carts when mobilized) are known to have a pair of opposite vertical side walls, a top wall, a back wall and a bottom wall defining an interior compartment with a front door mounted along a front vertical edge of one of the side walls for opening and closing a front opening to the compartment. Also, in the compartment racks are vertically spaced on the interiors of the side walls for supporting trays horizontally one above the other in the compartment. Multi-tray cabinets are also known to have an interior compartment with front and rear access openings that may be independently opened and closed by front and rear doors.
Room for sliding trays in and out of interior compartments of these cabinets is typically cramped and so is restricted primarily by a server using only one hand. This is the case whether the cabinet has only a front access opening or both front and rear access openings for reason that the server can only slide a food tray in or out of one of the openings at a time, that being the one opening that accommodates the server's hand.
Accordingly, there is a need in the art for an innovation that will overcome the deficiencies of the known prior art and problems that remain unsolved.

Referring now to FIGS. 1-5 and 9, there is illustrated an exemplary embodiment of a multi-tray cabinet in accordance with aspects of the present invention, being generally designated 100. The cabinet 100 includes a cabinet body 102 defining an interior compartment 104 and a compound opening 106 to the interior compartment 104. The cabinet 100 also includes a pair of front and top doors 108, 110 located on the cabinet body 102 adjacent and at an angle to one another. The front and top doors 108, 110 are mounted to the cabinet body 102 to undergo movement relative to one another and to the cabinet body 102 in order to open and close the compound opening 106.
More particularly, the cabinet body 102 is formed by a plurality of interconnected walls, for example, a pair of opposite spaced apart vertical side walls 112, 114, a horizontal bottom wall 116 and a vertical rear wall 118. These interconnected walls 112, 114, 116, 118 define and partially surround the interior compartment 104 and define the compound opening 106 thereto. In FIG. 9, there is shown an insulated construction of the cabinet body 102 incorporated by the interconnected walls. The compound opening 106 includes a front opening 120, extending from a horizontal front edge 122 of the horizontal bottom wall 116 and upward between vertical front edges 124, 126 of the opposite spaced apart vertical side walls 112, 114, and a top opening 128, merging with the front opening 120 and extending rearward between horizontal top edges 130, 132 of the opposite vertical side walls 112, 114 to a horizontal top edge 134 of the vertical rear wall 118. The front opening 120 and top opening 128 extend transversely, or at a right angle, to one another.
Front and top doors 108, 110 of the cabinet 100 have respective hinges 136, 138 connecting them to the cabinet body 102 so that the doors may undergo pivotal movement relative thereto in order to open and close the front and top openings 120, 128 of the compound opening 106. The lower edge 140 of the front door 108 is pivotally connected by the hinge 136 to the horizontal front edge 122 of the horizontal bottom wall 116 of the cabinet body 102.
