Abstract

A refrigerated cabinet door and door mounting frame structure for mounting a plurality of electrically heated refrigerator doors with each door having selectible left or right hinging.

Claims

1. A refrigerated cabinet door and door moUnting frame structure for mounting an array of electrically heated refrigerated cabinet doors with each door having separately selectable left or right hinging, comprising:

upper and lower elongated horizontal door mounting frame members;

first and second mutually spaced elongated vertical mounting frame members interconnecting said upper and lower members to define a door mounting frame;

at least one elongated vertical mullion interconnecting said horizontal frame members intermediate said first and second vertical frame members, said mullion dividing the door mounting frame into a plurality of individual door mounting frame sections;

a plurality of refrigerated cabinet doors, each door having an electrical connector means for connection to an external source of power;

means cooperating with said door mounting frame and doors for selectively pivotally mounting said doors in said frame sections, one each hinged with a separately selectable hinge axis in either left or right hand sides of each door mounting frame section;

a plurality of frame mounted electrical outlets, at least one each positioned on the first and second vertical mounting frame members, at least two each positioned on each mullion, each frame mounted electrical connector being adapted to engage a corresponding door electrical connector means when a door is hinged with its hinge axis adjacent thereto, said frame mounted electrical outlets being connectable to a source of external power, whereby electrical energy is supplied to each of said plurality of doors irrespective of their individual hinging orientations and whereby each door may be removed and reversed at will without changing the hinging orientation of any of the other doors.

2. The refrigerated cabinet door and door mounting frame structure of claim 1 further comprising:

a plurality of door stop means, one each connected between each door and its related door mounting frame section for limiting the opening of each door to a predetermined limit in both door hinging orientations.

3. The refrigerated cabinet door and door mounting frame structure of claim 2 wherein each of said doors comprises:

four rectangularly related door frame member defining a door frame;

a glass panel mounted within said door frame;

one of said door frame members having first and second aligned hinge pin mounting grooves formed at opposite ends thereof, symmetrically about the horizontal center line of said door.

4. The refrigerated cabinet door and door mounting frame structure of claim 3 wherein said upper and lower elongated horizontal door mounting frame members have a plurality of aligned hinge pin receiving apertures formed therein, each horizontal member having two such apertures for each individual door frame section, one such aperture being positioned adjacent each vertical mounting frame member and mullion.

5. The refrigerated cabinet door and door mounting frame structure of claim 4 further comprising a plurality of elongated hinge pins, two for each door mounting frame section, each such hinge pin having a first portion comprising a shaft member adapted to be selectively inserted in rotatable relationship into one of said hinge pin mounting grooves, and a second portion adapted to selectively project through one of said hinge pin receiving apertures, said second portion including means for securing said hinge pin to said frame member, whereby two such hinge pins may be selectively positioned on the upper and lower door mounting frame members in either the left or right hand side of each door frame section to selectively pivotally mount a corresponding door in either a hinge left or hinge right configuration.

6. The refrigerated cabinet door and door mounting frame structure of claim 2, wherein each of said door stop means comprises:

a pair of door stop arm mounting brackets positioned on said door symmetrically about the door horizontal center line;

an elongated door stop arm;

means for Pivotally mounting one end of said arm selectively to one of said mounting brackets as a function of the door hinging direction;

a longitudinal raceway of predetermined length symmetrically formed in one of said horizontal door mounting frame members and positioned within the corresponding individual door mounting'"'"''"'"'s frame section;

a stop block positioned within said raceway and being slidable along the lengthwise dimension thereof;

means for pivotally mounting the other end of said door stop arm to said stop block, whereby as said door is opened the stop block will be translated along said raceway, preventing further opening of said door when said stop block reaches the end of the raceway.

7. The refrigerated cabinet door and door mounting structure of claim 6 wherein said door stop means further comprises:

first and second springs positioned on opposed sides of said stop block within said raceway, said springs, respectively, preventing said door from slamming while closing and urging said door towards a closed position when open.

8. The refrigerated cabinet door and door mounting frame structure of claim 1, wherein there are a plurality of elongated mutually spaced vertical mullions interconnecting said horizontal frame members intermediate said first and second vertical frame members, each mullion having at least two electrical outlets adapted to electrically engage a corresponding door electrical connector means, said plurality of mullions dividing said door mounting frame into N+1 individual door frame sections, where N the number of vertical mullions.

9. A door and door mounting frame structure for mounting an electrically heated refrigerated cabinet door with selectable left or right articulation, comprising:

upper and lower elongated horizontal door mounting frame members;

left and right elongated vertical mounting frame members interconnecting said upper and lower elongated frame members to define a door mounting frame;

a refrigerated cabinet door having electrical connector means for connecting an external source of electrical power to said door;

means cooperating with said door mounting frame and door for selectively pivotally hinging said door in said frame in either a hinge left or hinge right configuration;

first and second frame mounted electrical outlets positioned respectively on the left and right frame members, each adapted to electrically engage said door electrical connector means when said door is hinged with a hinge axis adjacent a respective vertical frame member, said electrical outlets being connectable to a source of external power whereby electrical power is transmitted to said door when mounted adjacent either of said vertical frame members;

a pair of door stop arm mounting brackets positioned on said door symmetrically about the door'"'"''"'"'s horizontal center line;

an elongated door stop arm;

means for pivotally mounting one end of said arm selectively to one of said mounting brackets;

a longitudinal raceway of predetermined length, formed in one of said horizontal door mounting frame members;

a stop block positioned within said raceway and being slidable along the lengthwise dimension thereof; and

means for pivotally mounting the other end of said door stop arm to said stop block, whereby as said door is opened the stop block will be translated along said raceway being stopped and thus preventing further opening of said door when it reaches the end of the raceway.
