Definitions

  • the present invention relates to a door structure for refrigerated display cabinets comprising a generally rectangular frame including upper and lower frame members and a plurality of laterally spaced column members extending therebetween defining at least one door opening; a generally rectangular door; upper and lower hinge assemblies for hingedly mounting said door and said frame for swinging movement about a gene-rally vertical axis inwardly and outwardly with respect to said door opening; said upper hinge assembly including an upper hinge pin extending upwardly from said door and upper hinge means within which said upper hinge pin is disposed.
  • a door structure of the above mentioned type is known from US-A-3,629,972.
  • This known door -structure includes a rectangular door frame of extruded metal within which there are supported two or more spaced apart glass panels.
  • the glass panels are spaced such that there is a thin layer of "dead” air disposed between them which provides good insulating properties.
  • One or more of the glass panels and the door frame may be electrically heated to preclude formation of condensation thereon.
  • Each of the doors is mounted to the cabinet frame by hinge assemblies which include upper and lower hinge pins which are disposed at respective upper and lower corners of the doors.
  • the upper hinge pin assembly is received in a bushing. The bushing, however, does not permit adjustable mounting of the swing axis of the door.
  • US-A-4,209,946 does not relate to a door for refrigerated display cabinets but is related to positional adjustment of hinges of a window in a frame for correct alignment of the window.
  • the frame may include one or more vertically extending and laterally spaced vertical columns or mullions for providing the proper support and sealing surfaces for the doors. After this outer frame has been put in place within the opening of the refrigerated cabinet, it must be carefully aligned so that it forms a true rectangle as nearly as possible. Clamps, wedges, and other devices may be used to align and straighten the frame before it is fixed to the cabinet opening by suitable mechanical fasteners.
  • each of the doors within the frame will also be misaligned with respect thereto. As a result, all of the doors will appear to sag, and the entire face of the cabinet, with each of the doors “leaning” or “sagging” has what is referred to as a "saw-toothed” appearance. Doors may also become misaligned as the result of normal wear after repeated opening and closing.
  • This condition is unsightly, and may adversely affect the ease of opening and closing the doors of the cabinet. More importantly, this condition may adversely affect effective sealing between the cabinet and the gaskets provided on each of the doors. This obviously is very undesirable.
  • the refrigeration unit of the refrigerated cabinet is made to work harder to the detriment of energy efficiency and maintenance, and the goods stored within the cabinet may no longer be maintained at sufficiently low temperatures to assure freshness and lack of spoilage. Thus, it is important that this condition be corrected, for the sake of both attractive appearance as well as efficient storage of refrigerated goods.
  • the invention is characterized in that said upper hinge means are bracket means including lug means extending into said upper frame member and adjustment means for adjustable attachment of said bracket means to said upper frame member in a plurality of positions whereby the vertical swinging axis of said door may be shifted, and said upper frame member including a web portion that defines a slot within which said lug means and said upper hinge pin extend.
  • Said upper bracket means defines a hinge pin slot within which said upper hinge pin is disposed, said hinge pin slot being disposed adjacent to said lug means and adapted to prevent relative rotation of said hinge pin relative to said bracket means.
  • Said adjustment means comprises an elongated fastener slot defined by said bracket means through which an upper mechanical fastener extends for adjustably attaching said bracket means to said upper frame member. Since the hinge pin slot defined by the web portion is of somewhat elongated configuration, as is the fastener slot defined by the bracket, the bracket may be easily shifted or displaced longitudinally with respect to the web portion of the upper frame member before the fastener is fully tightened.
  • Said upper bracket means are reversibly attachable to said upper frame member.
  • a lower hinge bracket defines a pair of slots, the lower hinge pin being positionable in one of said slots whereby said door is hingedly mountable on said frame by said upper and lower hinge assemblies for opposite swinging movement with respect to said door opening.
  • Said lower hinge assembly includes a lower hinge pin extending downwardly from said door assembly and a lower hinge bracket within said lower hinge pin is disposed.
  • the lower hinge bracket is adjustably attached to said lower frame member by lower mechanical fastener means.
  • the lower hinge bracket includes stop means cooperative with said door assembly for limiting outward swinging movement of said door assembly with respect to said door opening.
  • the upper mechanical fastener and lower mechanical fastener means are respectively disposed such that they are accessible when that door is mounted within said upper and lower hinge assemblies.
  • the lower hinge bracket includes upstanding stop means which cooperate with said door for limiting the outward swinging movement thereof relative to said frame.
  • the lower hinge bracket includes hold-open means movable between a first position wherein said door is swingingly movable with respect to said frame and a second position wherein said door is maintained in a selected position relative to said frame.
  • a door structure for refrigerated-display cabinets comprising a generally rectangular frame including upper and lower frame members and a plurality of laterally spaced column members extending therebetween defining at least one door opening; upper and lower hinge assemblies for hingedly mounting said door on said frame for swinging movement about a generally vertical axis inwardly and outwardly with respect to said door opening; said upper hinge assembly including first adjustment means for shifting the swinging axis of said door assembly with respect to said frame; said lower hinge assembly including second adjustment means for shifting the swinging axis of said door assembly with respect to said door frame; said door structure being characterized by means for reversibly hingedly mounting said door on said frame for accommodating opposite swinging movement of said door with respect to said door opening, and said first and second adjustment means being repositionable on said frame for effecting selected realignment of said door for such opposite swinging movement.
  • the simple hinge mounting arrangement for the door structure facilitates readily adjustment and alignment of the door assemblies within the cabinet frame.
  • the hinge mounting arrangement of the present invention is adaptable for use with reversible doors, i.e., installations in which the doors may be hinged to open along either their right or left side edges. Because many of the refrigerated door structures presently in use are such reversible type, adaptability of the hinge mounting arrangement of the subject invention greatly increases its versatility and provides an alignment correcting arrangement which is suitable for a great many door installations. When the slide stop is moved to one position with respect to the lower hinge bracket, the door structure may be opened and closed in a normal fashion.
  • the door structure may be opened and the slide stop manipulated by sliding it with respect to the lower hinge bracket so that the door assembly is then maintained in an open position.
  • the upper hinge pin bracket Before the mechanical fastener is fully tightened, simple and effective adjustment of the upper hinge pin bracket with respect to the top frame member is possible. Since the slot in the upper frame member is elongated, the tap or lug element of the upper hinge bracket, and the upper hinge pin which project therein are shiftable or movable with respect to the slot in the upper frame member. This shifting or displacement is accommodated by the elongated slot provided in the hinge bracket through which the mechanical fastener connecting the bracket to the upper frame member extends. In order to assist installation or maintenance personal in achieving correct alignment of the door assembly, the upper hinge pin bracket may include gauge marks or other indicia for establishing correct alignment of the upper hinge pin bracket with the upper frame member. When this is achieved, the mechanical fastener may be fully tightened so that the hinge bracket is held tightly and securely to the upper frame member.
  • the door structure is moved into position adjacent to the door opening.
  • the door structure is then lifted into the door opening, and the upper hinge pin of the door structure is within the upper hinge pin slots of the upper hinge pin bracket and the upper frame member, respectively.
  • the lower hinge pin of the door assembly is able to clear the lower frame member of the door frame and the lower hinge mounting bracket, whereby the bottom of the door structure may then be swung inwardly so that the lower hinge pin may be fitted within the hinge pin slot of the lower hinge bracket.
  • the door structure is then lowered slightly and is now supported by the frame and the upper and lower hinge brackets.
  • FIG. 1 there is illustrated the front of a refrigerated display case in which is installed a door structure 10 having a plurality of glass panel doors.
  • the door structure 10 has been shown as including three hinged doors, but it will be understood that the subject invention is adaptable for use with any number of doors.
  • the door structure 10 includes a cabinet frame 12which extends generally about the periphery of the front of the display cabinet.
  • the frame 12 includes a top or upper frame member 14, a bottom or lower frame member 16, and suitably laterally spaced side frame members 18 extending therebetween.
  • the frame members are adapted to be arranged in a rectangular configuration with the respective end portion of the frame members forming 90 degree angles in each of the corners of the frame.
  • the frame 12 also includes one or more column members 20 which extend vertically between the lower frame member 16 and the upper frame member 14 and are connected thereto.
  • the column members 20 not only provide rigidification of the door frame 12 and the door structure 10, but also define sealing surfaces against which portions of the doors of the door structure 10 engage and seal for effective sealing of the refrigerated cabinet.
  • the column members 20 may also be equipped with electrical conduits for delivering electrical power to anti-condensation devices within the doors of the door structure 10.
  • the refrigerated door structure 10 includes the insulated glass doors 24 hinged to the door frame 12 which are adapted to swing inwardly and outwardly with respect to the door frame 12 so that the inside of the refrigerated cabinet is easily accessible by purchasers, or by store personnel for stocking of the cabinet.
  • Each of the doors 24 is mounted for swinging movement by an upper hinge assembly 26 and a lower hinge assembly 28 connected to the upper frame member 14 and the lower frame member 16, respectively of the frame 12.
  • Each of the doors 24 comprises an upper door frame member 30 and a lower door frame member 32 provided respectively at the top and bottom of the doors 24.
  • Each door further includes an inner side frame member 34 and an outer side frame member 36 extending vertically between respective ends of the upper and lower frames 30 and 32.
  • Each door 24 includes a plurality of glass panels 38 which are carried by the door frame members in laterally spaced relation to one another. Typically, two or more glass panels 38 are provided such that a layer of dormant or "dead" air is disposed between each adjacent panel, this construction exhibiting desirable insulation properties.
  • Each of the doors 24 is provided with a door handle 40 on its outer side frame member 36 for convenience in opening the door.
  • Each of the doors 24 is provided with an upper hinge pin 42 and a lower hinge pin 44 disposed in respective upper and lower corner portions of the doors 24.
  • the upper hinge pin 42 is disposed in upstanding relationship to the upper door frame member 30, while the lower hinge pin 44 projects correspondingly downwardly from the lower door frame member 32.
  • Each of the hinge pins 42 and 44 are typically of a square or rectangular configuration in cross-section.
  • the door 24 is pivotable with respect to the hinge pins 42 and 44, thus providing hinging movement of the door 24 relative to the door frame 12. Further, one or both of the hinge pins 42 and 44 is usually associated with a spring loading mechanism carried within the door 24 so that each of the doors 24 is biased into sealing engagement with the sealing portions of the door frame 12, and so that each of the doors 24 is self- closing after it has been swung open.
  • the upper and lower hinge assemblies 26 and 28 further include an upper hinge bracket 46 and a lower hinge bracket 48, respectively.
  • the upper hinge assembly 26 also includes a hinge pin lock 50 which is adapted to fit about the upper hinge pin 42 for preventing accidental removal of the door 24 from the door frame 12 as will be more fully described hereinafter.
  • the lower hinge assembly 28 may also include a hold open slide 52 which is slidably disposed with respect to the lower hinge bracket 48, and movable between a first position where the door 24 may be swung inwardly and outwardly with respect to the door frame, and a second position where the door 24 is maintained in open relation to the door frame 12.
  • the upper hinge bracket 46 comprises a generally flat plate which defines an upper hinge pin slot 54 therein.
  • the hinge pin slot 54 is of a rectangular configuration, and is adapted to receive the upper hinge pin 42 therein.
  • the hinge pin slot 54 is dimensioned such that transverse and rotation of the upper hinge pin 42 with respect to the upper hinge bracket 46 is prevented.
  • the upper hinge pin 42 engages or abuts portions of the hinge bracket 46 defined by the hinge pin slot 54.
  • the upper hinge bracket 46 is further provided with an upstanding or projecting upper hinge lug 56 which is disposed in upstanding relation on the bracket 46, and is adjacent to the hinge pin slot 54.
  • the upper hinge bracket 46 also defines a generally elongated upper fastener slot 58.
  • the upper hinge bracket 46 may also include one or more locating gauge marks 59 or other suitable indicia for assisting in alignment of the doors 24 within the door frame 12 as will be described.
  • the upper frame member 14 of the door frame 12 includes a generally horizontally disposed web portion 60.
  • the web portion 60 will typically comprise an integral portion of the upper frame member 14.
  • the web portion 60 defines upper frame member hinge slots 62 and 62' each having a generally rectangular, somewhat elongated configuration. Only one of the slots 62 or 62' will be employed at a time, both being provided for reversibility of mounting the hinge bracket 46.
  • Web portion 60 is adapted to receive a suitable mechanical fastener 64 within a fastener hole 66 for affixing the upper hinge bracket 46 to the upper frame member 14.
  • Mechanical fastener 64 may be of a self-tapping variety, or may be held in position by a suitable lock nut 68 ( Figure 3).
  • the bracket 46 in order to attach the upper hinge bracket 46 to the upper frame member 14, the bracket 46 is fitted against the lower surface of the web portion 60 of the upper frame member 14 such that the lug 56 extends upwardly into the frame member hinge pin slot 62.
  • the bracket 46 is held in position by inserting mechanical fastener 64 through the fastener slot 58 in the bracket 46 and into fastener hole 66 defined by the web portion 60.
  • the hinge pin slot 62 (or 62') defined by the web portion 60 is of somewhat elongated configuration, as is the fastener slot 58 defined by the bracket 46, the bracket 46 may be easily shifted or displaced longitudinally with respect to the web portion 60 of the upper frame member 14 before the fastener 64 is fully tightened.
  • the slot 54 defined by the bracket 46 is adapted to receive the upper hinge pin 42 of the door 24, the position in which the hinge pin 42 is maintained within the slot 54 is easily and readily adjustable for shifting the hinging axis of the door 24 for effecting correct alignment thereof with respect to the sealing surfaces provided by the door frame 12. Locating gauge marks 59 assist in correctly aligning the bracket 46 with respect to the upper frame member 14, and after this is accomplished the mechanical fastener 64 may be fully tightened such that hinge bracket 46 is maintained in fixed relation to the upper frame member 14.
