Doors of all kinds are mounted to hinges for opening and closing of the doors. For example, a refrigerator door may be mounted to a hinge, which is mounted to a body of a refrigerator to allow the door to rotate open and closed under control of the hinge. Manufacturing tolerances for the door, the cabinet, and the hinge can result in a tolerance stack-up that can create a gap between a door hinge bracket and the door. As a result, the hinge may not be mounted level relative to the mounting surface of the door and/or the hinge may not be properly supported to approximately equally distribute the forces on the hinge.
In an example embodiment, a hinge support is provided. The hinge support may include a brace, a trestle, and a positioning device. The brace is mounted to a surface of a door and comprises a base wall, a first side wall, a second side wall, and a positioning wall. The first side wall, the second side wall, and the positioning wall extend from the base wall in a first direction. The first side wall has a first sloped surface, and the second side wall has a second sloped surface. The trestle includes a top wall, a third side wall, a fourth side wall, and a support wall. The third side wall, the fourth side wall, and the support wall extend from the top wall in a second direction. The third side wall has a third sloped surface, and the fourth side wall has a fourth sloped surface. The positioning device mounts the trestle to the brace, is supported by the support wall, and is positioned to abut the positioning wall when mounting the trestle to the brace. At least a portion of the third sloped surface is positioned to slide along the first sloped surface under control of the positioning device, and at least a portion of the fourth sloped surface is positioned to slide along the second sloped surface under control of the positioning device to position the top wall of the trestle adjacent a door bracket of a hinge to support the door bracket relative to the surface of the door.
In another example embodiment, a hinge assembly is provided. The hinge assembly may include a device bracket, a door bracket, an arm, and a hinge support. The device bracket mounts to a device surface of a device. The door bracket mounts to a door of the device. The arm is mounted for rotation about a first pin and about a second pin, wherein the first pin is mounted to the device bracket and the second pin is mounted to the door bracket. The hinge support may include a brace, a trestle, and a positioning device. The brace mounts to a door surface of the door, and may include a base wall, a first side wall, a second side wall, and a positioning wall. The first side wall, the second side wall, and the positioning wall extend from the base wall in a first direction. The first side wall has a first sloped surface, and the second side wall has a second sloped surface. The trestle may include a top wall, a third side wall, a fourth side wall, and a support wall. The third side wall, the fourth side wall, and the support wall extend from the top wall in a second direction. The third side wall has a third sloped surface, and the fourth side wall has a fourth sloped surface. The positioning device mounts the trestle to the brace, is supported by the support wall, and is positioned to abut the positioning wall when mounting the trestle to the brace. At least a portion of the third sloped surface is positioned to slide along the first sloped surface under control of the positioning device and at least a portion of the fourth sloped surface is positioned to slide along the second sloped surface under control of the positioning device to position the top wall of the trestle adjacent the door bracket to support the door bracket relative to the door surface.
In another example embodiment, a device is provided. The device may include a body, a door, a hinge pivotally mounting the door to the body, and a hinge support. The hinge may include a device bracket mounted to a surface of the body, a door bracket mounted to the door, and an arm mounted for rotation about a first pin and about a second pin. The first pin is mounted to the device bracket, and the second pin is mounted to the door bracket. The hinge support may include a brace, a trestle, and a positioning device. The brace is mounted to a door surface of the door and may include a base wall, a first side wall, a second side wall, and a positioning wall. The first side wall, the second side wall, and the positioning wall extend from the base wall in a first direction opposite the door surface. The first side wall has a first sloped surface, and the second side wall has a second sloped surface. The trestle may include a top wall, a third side wall, a fourth side wall, and a support wall. The third side wall, the fourth side wall, and the support wall extend from the top wall in a second direction that is opposite the first direction. The third side wall has a third sloped surface, and the fourth side wall has a fourth sloped surface. The positioning device mounts the trestle to the brace, is supported by the support wall, and is positioned to abut the positioning wall when mounting the trestle to the brace. At least a portion of the third sloped surface is positioned to move along the first sloped surface under control of the positioning device and at least a portion of the fourth sloped surface is positioned to move along the second sloped surface under control of the positioning device to position the trestle adjacent the door bracket to support the door bracket relative to the door surface.

Though the illustrative embodiments include the positioning device, the positioning device is not required in alternative embodiments. For example, friction between the sloped surfaces of the side walls of trestle 244 and brace 242 after insertion of the fasteners to mount door bracket 200 to exterior edge surface 208 of second door 108 may provide sufficient force to mount trestle 244 in abutment at the desired location on brace 242. Thus, hinge support 240 may not include screw 246, nut 400, or cap 402. Further, hinge support 240 may not include positioning wall 406 of brace 242 or support wall 454, nut support platform 492, and slot 490 of trestle 244. Similarly, friction between the sloped surfaces of the side walls of second trestle 1004 and second brace 1002 after insertion of the fasteners to mount door bracket 200 to exterior edge surface 208 of second door 108 may provide sufficient force to mount second trestle 1004 in abutment at the desired location on second brace 1002. Thus, second hinge support 1000 may not include screw 246, nut 400, or cap 402. Further, second hinge support 1000 may not include positioning wall 1012 of second brace 1002 or support wall 1042, nut support platform 1060, and slot 1058 of second trestle 1004.
Though the illustrative embodiments include sloped surfaces that are generally smooth, smooth surfaces are not required for the sloped surface of trestle 244 and brace 242. For example, the sloped surfaces of the side walls of trestle 244 and brace 242 may include a plurality of stepped surfaces that are complimentary and allow adjustment of the position of abutment of trestle 1004 with brace 1002. Similarly, the sloped surfaces of the side walls of second trestle 1004 and second brace 1002 may include a plurality of stepped surfaces that are complimentary and allow adjustment of the position of abutment of second trestle 1004 with second brace 1002. As another alternative embodiment, the sloped surfaces of the side walls of trestle 244 and brace 242 may include a textured surface. In these alternative embodiments, the positioning device is not required, though it may be included.
In the illustrative embodiments, a channel is formed between the sloped surfaces of the side walls of hinge support 240 and the sloped surfaces of the side walls of second hinge support 1000. However, in alternative embodiments, the sloped surfaces of the side walls may be joined by a solid surface. For example, a first surface may connect at least a portion of first sloped surface 1016 of second brace 1002 to second sloped surface 1022 of second brace 1002, and/or a second surface may connect at least a portion of first sloped surface 1050 of second trestle 1004 to second sloped surface of second trestle 1004. The first surface may extend all or part of the way towards base wall 1006 of second brace 1002, and/or the second surface may extend all or part of the way towards top wall 1040 of second trestle 1004. A similar modification may be made to the sloped surfaces of hinge support 240. In these alternative embodiments, the positioning device is not required, though it may be included. Additionally, in these alternative embodiments, the sloped surfaces may include a plurality of stepped surfaces that are complimentary.
