Definitions
- the present invention relate generally to commercial refrigerator door assemblies and more particularly to an adjustable door mounting arrangement for such door assemblies.
- refrigerator door assemblies There exists a wide variety of commercial refrigerator door assemblies.
- One very common type utilizes glass panel refrigerator doors, such as are illustrated in the Kurowski U.S. Patents Nos. 2,987,782, and 3,131,421.
- Such refrigerator door assemblies are widely used in a variety of commercial installations of refrigerated display cases and cabinets from which purchasers may select refrigerated beverages, foods, and other products.
- Each door assembly is provided with suitable sealing gaskets in order to effect efficient sealing of the display cabinet when the doors are closed.
- 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 door assemblies. 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.
- Door assemblies 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 door assemblies. 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.
- a simple hinge mounting arrangement for the door assemblies for commercial refrigerated display cabinets which facilitates ready 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 door assemblies, 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 assemblies presently in use are such reversible types, 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.
- Door assemblies of the type to which the subject invention pertains typically include a rectangular door frame of extruded metal within which is 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 door assemblies 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. These pins are typically of a square or rectangular cross-section, and each door is pivoted with respect thereto for providing hinging action between the door and the cabinet frame.
- the hinge assemblies usually incorporate a spring loading mechanism such that the door tends to close itself after it is opened to and sealingly engage surfaces of the frame.
- Hinge assemblies in accordance with the present invention include upper and lower hinge brackets provided for mounting the door within the frame, and for adjusting the rotational axis of the door.
- the lower hinge bracket comprises a generally elongated flat plate which includes an aperture adapted to receive the lower hinge pin of the door and to prevent the rotation of same with respect to the cabinet frame.
- the lower hinge bracket is also provided with suitable slots to receive mechanical fasteners for adjustably attaching the lower hinge bracket to the bottom of the cabinet frame.
- the hinge bracket may typically include an upstanding projection or peg which acts as a door stop for preventing excessive opening of the door.
- the lower hinge assembly may also include a generally elongated slide stop fastened to the lower hinge bracket for sliding movement with respect thereto.
- the door assembly When the slide stop is moved to one position with respect to the lower hinge bracket, the door assembly may be opened and closed in a normal fashion. However, if it is desired to maintain the door assembly in an open position, such as for maintenance or for stocking goods within the refrigerated cabinet, the door assembly 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 opened position.
- the upper hinge assembly incorporating the present invention includes an upper hinge bracket which is adapted to cooperate with the upper frame member of the frame for providing adjustable mounting of the upper hinge pin of the door assembly.
- the upper hinge bracket includes a cut-out or slot portion adapted to receive the upper hinge pin of the door assembly.
- the upper hinge bracket further includes an upstanding hinge tab or lug which is disposed adjacent to the upper hinge pin slot, and extends upwardly from the hinge bracket.
- the hinge bracket also defines an elongated slot which is adapted to receive a suitable mechanical fastener.
- the top of the cabinet frame includes an elongated cut-out or slot portion adapted to receive therein the upstanding hinge tab or lug of the upper hinge bracket and the upper hinge pin.
- the top frame member also defines a suitable hole or cut-out for receiving a mechanical fastener which fits through the slotted portion of the upper hinge bracket.
- 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. Because the slot in the upper frame member is elongated, the tab 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.
- 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.
- a hinge lock is fitted about the upper hinge pin between the top of the door assembly and the upper hinge bracket to keep the door in place.
- the hinge lock usually includes a resilient C-shape portion which fits about and engages a portion of the upper hinge pin and prevents the door assembly from being lifted out of the door frame. If necessary, further alignment of the door assembly is easily accomplished since the upper and lower hinge brackets may be readily adjusted without removal of the door assembly from the frame. It is now a simple matter to make any necessary electrical connections between the door assembly and the frame, and to make any final adjustments to the hinge mechanisms of the door assembly.
- 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 door assemblies.

Abstract
Description
- The present invention relate generally to commercial refrigerator door assemblies and more particularly to an adjustable door mounting arrangement for such door assemblies.
- There exists a wide variety of commercial refrigerator door assemblies. One very common type utilizes glass panel refrigerator doors, such as are illustrated in the Kurowski U.S. Patents Nos. 2,987,782, and 3,131,421. Such refrigerator door assemblies are widely used in a variety of commercial installations of refrigerated display cases and cabinets from which purchasers may select refrigerated beverages, foods, and other products.
- Commercial refrigerator door assemblies are often of the type in which glass panels are mounted in a metal supporting door frame. One or more door assemblies are generally mounted in a metal outer frame or casing, and are frequently arranged side-by-side. Each door assembly is provided with suitable sealing gaskets in order to effect efficient sealing of the display cabinet when the doors are closed.
- Installation of refrigerated cabinet door assemblies of the above type is usually effected by installing a relatively large rectangular metal frame about the front of the display cabinet. 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 door assemblies. 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.
- Unfortunately, the installation of the frame in the above-described manner is not always performed correctly. As a result, the corners of the frame are not disposed at right angles, and the frame does not define the desired rectangular configuration. This is undesirable for several reasons. Because the frame supports each of the door assemblies for hinging movement with respect thereto, the alignment of the doors is dependent upon correct alignment of the cabinet or outer frame.
- If the outer frame is misaligned, 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. Door assemblies 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 door assemblies. 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.
- Heretofore, the correction of misaligned frames and door assemblies has been time consuming and labor intensive. It was necessary for the outer frame to be realigned. This frequently necessitated shutting off the refrigeration unit, removing the contents from the cabinet for storage elsewhere under refrigeration, and removal of the door assemblies in order to properly align the door frame. Without such corrective action, the above-described problems would continue to exist, to the detriment of efficient refrigerated storage and convenient consumer use.
- Thus, the introduction of a simple, easy to install, and readily adjusted door mounting arrangement would be desirable both for new refrigerated cabinet door assemblies, as well as for retrofitting to existing refrigerated cabinet door assemblies.
- In accordance with the present invention, there is provided a simple hinge mounting arrangement for the door assemblies for commercial refrigerated display cabinets which facilitates ready 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 door assemblies, 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 assemblies presently in use are such reversible types, 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.
- Door assemblies of the type to which the subject invention pertains typically include a rectangular door frame of extruded metal within which is 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 door assemblies 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. These pins are typically of a square or rectangular cross-section, and each door is pivoted with respect thereto for providing hinging action between the door and the cabinet frame. The hinge assemblies usually incorporate a spring loading mechanism such that the door tends to close itself after it is opened to and sealingly engage surfaces of the frame.
- Hinge assemblies in accordance with the present invention include upper and lower hinge brackets provided for mounting the door within the frame, and for adjusting the rotational axis of the door. The lower hinge bracket comprises a generally elongated flat plate which includes an aperture adapted to receive the lower hinge pin of the door and to prevent the rotation of same with respect to the cabinet frame. The lower hinge bracket is also provided with suitable slots to receive mechanical fasteners for adjustably attaching the lower hinge bracket to the bottom of the cabinet frame. The hinge bracket may typically include an upstanding projection or peg which acts as a door stop for preventing excessive opening of the door.
- The lower hinge assembly may also include a generally elongated slide stop fastened to the lower hinge bracket for sliding movement with respect thereto. When the slide stop is moved to one position with respect to the lower hinge bracket, the door assembly may be opened and closed in a normal fashion. However, if it is desired to maintain the door assembly in an open position, such as for maintenance or for stocking goods within the refrigerated cabinet, the door assembly 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 opened position.
- The upper hinge assembly incorporating the present invention includes an upper hinge bracket which is adapted to cooperate with the upper frame member of the frame for providing adjustable mounting of the upper hinge pin of the door assembly. The upper hinge bracket includes a cut-out or slot portion adapted to receive the upper hinge pin of the door assembly. The upper hinge bracket further includes an upstanding hinge tab or lug which is disposed adjacent to the upper hinge pin slot, and extends upwardly from the hinge bracket. The hinge bracket also defines an elongated slot which is adapted to receive a suitable mechanical fastener.
- In order to provide adjustable hinge mounting of the upper hinge pin, the top of the cabinet frame includes an elongated cut-out or slot portion adapted to receive therein the upstanding hinge tab or lug of the upper hinge bracket and the upper hinge pin. The top frame member also defines a suitable hole or cut-out for receiving a mechanical fastener which fits through the slotted portion of the upper hinge bracket. Thus, in order to prepare the frame for mounting of the upper hinge pin therein, the upper hinge bracket is fitted to the top frame member, with the upstanding tab of the hinge bracket projecting into the hinge slot provided in the upper frame member. A suitable mechanical fastener is inserted through the elongated slot defined in the hinge bracket and suitably fastened to the web of the upper frame member.
- 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. Because the slot in the upper frame member is elongated, the tab 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 personnel 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.
- Installation of the door assembly to the .frame structure is now a simple and straightforward matter in that the door assembly is moved into position adjacent to the door opening. The door assembly is then lifted into the door opening, and the upper hinge pin of the door assembly is fitted within the upper hinge pin slots of the upper hinge pin bracket and the upper frame member, respectively. As the door assembly is lifted into the door frame, 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 assembly 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 assembly is then lowered slightly, and is now supported by the frame and the upper and lower hinge brackets. A hinge lock is fitted about the upper hinge pin between the top of the door assembly and the upper hinge bracket to keep the door in place. The hinge lock usually includes a resilient C-shape portion which fits about and engages a portion of the upper hinge pin and prevents the door assembly from being lifted out of the door frame. If necessary, further alignment of the door assembly is easily accomplished since the upper and lower hinge brackets may be readily adjusted without removal of the door assembly from the frame. It is now a simple matter to make any necessary electrical connections between the door assembly and the frame, and to make any final adjustments to the hinge mechanisms of the door assembly.
- Should it become necessary during the service life of the door structure to adjust the alignment of one or more of the door assemblies, it is now a simple matter of loosening the mechanical fastener provided for fixing the upper hinge bracket to the upper frame member, and shifting or displacing the upper hinge bracket with respect to the upper frame member such that the door assembly is brought into alignment with respect to the door opening. Similarly, adjustment of the lower hinge bracket may be accomplished by loosening its fasteners and shifting it with respect to the lower member of the door frame. Because of the novel arrangement of the elements of the subject hinge mounting arrangement, it will usually be totally unnecessary to even remove the door assembly from the door frame when these adjustments are made, thus greatly simplifying alignment of the door assemblies for effective sealing of the refrigerated cabinet and enhanced appearance.

- While the subject invention is susceptible to embodiment in different forms, there is shown in the drawings and will hereinafter be described a preferred embodiment with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiment illustrated.
- With reference now to Figure 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 door assemblies. For purposes of illustration, the door structure 10 has been shown as including three hinged door assemblies, but it will be understood that the subject invention is adaptable for use with any number of door assemblies.
- The door structure 10 includes a
cabinet frame 12 which extends generally about the periphery of the front of the display cabinet. The frame 12 - includes a top orupper frame member 14, a bottom orlower frame member 16, and suitably laterally spacedside 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. Theframe 12 also includes one or more columns ormullions 20 which extend vertically between thelower frame member 16 and theupper frame member 14 and are connected thereto. Themullions 20 not only provide rigidification of thedoor frame 12 and the door structure 10, but also define sealing surfaces against which portions of the door assemblies of the door structure 10 engage and seal for effective sealing of the refrigerated cabinet. Themullions 20 may also be equipped with electrical conduits for delivering electrical power to anti-condensation devices within the door assemblies of the door structure 10. - The refrigerated door structure 10 includes the insulated
glass door assemblies 24 hinged to thedoor frame 12 which are adapted to swing inwardly and outwardly with respect to thedoor 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 thedoor assemblies 24 is mounted for swinging movement by anupper hinge assembly 26 and alower hinge assembly 28 connected to theupper frame member 14 and thelower frame member 16, respectively of theframe 12. Each of thedoor assemblies 24 comprises an upperdoor frame member 30 and a lowerdoor frame member 32 provided respectively at the top and bottom of thedoor assembly 24. Each door assembly further includes an innerside frame member 34 and an outerside frame member 36 extending vertically between respective ends of the upper andlower frames - Each
door assembly 24 includes a plurality ofglass panels 38 which are carried by the door frame members in laterally spaced relation to one another. Typically, two ormore 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 thedoor assemblies 24 is provided with adoor handle 40 on its outerside frame member 36 for ccnvenience in opening the door assembly. - With further reference to Figure 1, and reference to Figures 2-4, the
upper hinge assembly 26 and thelower hinge assembly 28 of each of thedoor assemblies 24 will now be described. Each of thedoor assemblies 24 is provided with anupper hinge pin 42 and alower hinge pin 44 disposed in respective upper and lower corner portions of thedoor assembly 24. As shown in Figure 2, theupper hinge pin 42 is disposed in upstanding relationship to the upperdoor frame member 30, while thelower hinge pin 44 projects correspondingly downwardly from the lowerdoor frame member 32. Each of the hinge pins 42 and 44 are typically of a square or rectangular configuration in cross-section. - The
door assembly 24 is pivotable with respect to the hinge pins 42 and 44, thus providing hinging movement of thedoor assembly 24 relative to thedoor frame 12. Further, one or both of the hinge pins 42 and 44 is usually associated with a spring loading mechanism carried within thedoor assembly 24 so that each of thedoor assemblies 24 is biased into sealing engagement with the sealing portions of thedoor frame 12, and so that each of thedoor assemblies 24 is self closing after it has been swung open. - The upper and
lower hinge assemblies upper hinge bracket 46 and alower hinge bracket 48, respectively. Theupper hinge assembly 26 also includes ahinge pin lock 50 which is adapted to fit about theupper hinge pin 42 for preventing accidental removal of thedoor assembly 24 from thedoor frame 12 as will be more fully described hereinafter. Thelower hinge assembly 28 may also include a holdopen slide 52 which is slidably disposed with respect to thelower hinge bracket 48, and movable between a first position where thedoor assembly 24 may be swung inwardly and outwardly with respect to the door frame, and a second position where thedoor assembly 24 is maintained in open relation to thedoor frame 12. - With reference now to the
upper hinge assembly 26 as shown in Figures 2 and 3, theupper hinge bracket 46 comprises a generally flat plate which defines an upper hinge pin cut-out or slot 54 therein. Thehinge pin slot 54 is of a rectangular configuration, and is adapted to receive theupper hinge pin 42 therein. Thehinge pin slot 54 is dimensioned such that transverse and rotation of theupper hinge pin 42 with r-espect to theupper hinge bracket 46 is prevented. Thus, theupper hinge pin 42 engages or abuts portions of thehinge bracket 46 defined by thehinge pin slot 54. - The
upper hinge bracket 46 is further provided with an upstanding or projecting upper hinge tab or lug 56 which is disposed in upstanding relation on thebracket 46, and is adjacent to thehinge pin slot 54. Theupper hinge bracket 46 also defines a generally elongatedupper fastener slot 58. Theupper hinge bracket 46 may also include one or more locating guage marks 59 or other suitable indicia for assisting in alignment of thedoor assemblies 24 within thedoor frame 12 as will be described. - In order to provide a suitable mounting for the
hinge assembly 26 to the upper portion of thedoor frame 12, theupper frame member 14 of thedoor frame 12 includes a generally horizontally disposedweb portion 60. Theweb portion 60 will typically comprise an integral portion of theupper frame member 14. Theweb portion 60 defines upper framemember hinge slots slots 62 or 62' will be employed at a time, both being provided for reversibility of mounting thehinge bracket 46. -
Web portion 60 is adapted to receive a suitablemechanical fastener 64 within afastener hole 66 for affixing theupper hinge bracket 46 to theupper 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). - Thus, it will be readily observed that in order to attach the
upper hinge bracket 46 to theupper frame member 44, thebracket 46 is fitted against the lower surface of theweb portion 60 of theupper frame member 14 such that the hinge tab or lug 56 extends upwardly into the frame memberhinge pin slot 62. Thebracket 46 is held in position by insertingmechanical fastener 64 through thefastener slot 58 in thebracket 46 and intofastener hole 66 defined by theweb portion 60. It will be appreciated that since the hinge pin slot 62 (or 62') defined by theweb portion 60 is of somewhat elongated configuration, as is thefastener slot 58 defined by thebracket 46, thebracket 46 may be easily shifted or displaced longitudinally with respect to theweb portion 60 of the upper frame.member 14 before thefastener 64 is fully tightened. Because the cut-out or slot 54 defined by thebracket 46 is adapted to receive theupper hinge pin 42 of thedoor assembly 24, the position in which thehinge pin 42 is maintained within theslot 54 is easily and readily adjustable for shifting the hinging axis of thedoor assembly 24 for effecting correct alignment thereof with respect to the sealing surfaces provided by thedoor frame 12. Locating gauge marks 59 assist in correctly aligning thebracket 46 with respect to theupper frame member 14, and after this is accomplished themechanical fastener 64 may be fully tightened such thathinge bracket 46 is maintained in fixed relation to theupper frame member 14. - With further reference to Figure 2 and Figure 4, the
lower hinge bracket 48 of thelower hinge assembly 28 comprises a generally flat plate which defines lower hinge pin cut-outs orslots 70 and 70'. As is the case of the cut-out or slot 54 provided in theupper hinge bracket 46, the cut-outs orslots 70 and 70' provided in thelower hinge bracket 48 are generally rectangular and are adapted to receive thelower hinge pin 44 such that longitudinal movement and rotation between thehinge pin 44 and thelower hinge bracket 48 is prevented. - Although only one of the
slots 70 and 70' is used at a time for receiving thehinge pin 44, they both are provided for reversibility at thelower hinge bracket 48. Thelower hinge bracket 48 further defines a pair oflower fastener slots 72 disposed at opposite ends thereof, for adjustably fastening thebracket 48 to thelower frame member 16 of thedoor frame 12. Thehinge bracket 48 may also include an upstanding door stop projection or peg 74 which is adapted to cooperate with a suitable door stop mechanism 75 (Fig. 4) carried by thedoor assembly 24 for preventing excessive opening of the door assembly with respect to the door frame, which usually permits maximum opening of approximately 90 degrees of the door assembly relative to the door frame. - The
lower hinge bracket 48 is suitably connected to a generally horizontally disposed lowerframe web portion 76 of thelower frame member 16 bymechanical fasteners 78 which extend through thefastener slots 72 in thehinge bracket 48 into web fastener holes 80, 81 provided in theweb portion 76 of thelower frame member 16. An additional fastener hole 80' is defined by theweb portion 76 for accommodating reversibility of thebracket 48 as will be described.Fasteners 78 may be of the self-tapping variety, or may be provided with lock nuts 82 (Fig. 4) for adjustably attaching thelower hinge bracket 48 to theweb portion 76 of thelower frame member 16. - The
lower hinge assembly 28 may include the holdopen slide 52 which is adapted to be slidably attached to thelower hinge bracket 48. The holdopen slide 52 includes a generallyelongated slide slot 84 through which aslide bushing 86 and afastener 88 extend. Theslide stop 52 is positioned on top of thelower hinge bracket 48 with thefastener 88 extending through thebushing 86 and theslide slot 84 into thebracket 48. It will be observed that theslide stop 52 is thereby slidable with respect to thelower bracket 48 between a first position in which the door assembly 24.may be opened and closed in a normal fashion, and a second position wherein thedoor 24 may be maintained in open relation to thedoor frame 12 with theslide stop 52 preventing the closing of the door assembly. - After the
frame 12 of the door structure 10 has been positioned within the opening of the display cabinet for which it is provided, the door frame is aligned so that it defines a rectangle as nearly as is practicable. Thedoor frame 12 is then secured within the door opening, and suitably caulked and sealed. Upper andlower hinge brackets door assemblies 24 for mounting therein. - Each
door 24 is easily installed in its respective upper and lower hinge assemblies by lifting the door into the frame such that theupper hinge pin 42 extends into and through thehinge pin slot 54 defined by theupper hinge bracket 46 and theslot 62 defined by theweb portion 60 of theupper frame member 14. Thedoor 24 is lifted sufficiently so that thelower hinge pin 44 is able to clear thelower hinge bracket 48, and the lower portion of the door may be swung inwardly of thedoor frame 12 to inserthinge pin 44 in thehinge pin slot 70 defined by thelower hinge bracket 48. Theentire door assembly 24 is then carefully lowered within theframe 12 to insert thelower hinge pin 44 into thehinge pin slot 70 defined bylower hinge bracket 48. After thedoor assembly 24 has been installed, thehinge pin lock 50 is fitted about theupper hinge pin 42 so that thedoor assembly 24 cannot be accidentally lifted out of theframe 12. - It will be observed that adjustment of the
hinge assemblies upper hinge bracket 46 may be repositioned with respect to theweb portion 60 of theupper frame member 14 by partially loosening themechanical fastener 64 extending therethrough and shifting thebracket 46 with respect to theweb portion 60. Depending upon the dimensions of the upperframe member slot 62, a substantial amount of adjustment or play may be provided. - Similarly, the elongated nature of
slots 72 defined bylower hinge bracket 48 permits shifting of thebracket 48 with respect tolower frame 16 by merely looseningfasteners 78, thus accommodating further adjustment of the hinge axis of the door assembly. Thus, correct alignment of thedoor assemblies 24 may be easily and simply accomplished. - This alignment procedure may be simply performed to compensate for sagging of the door due to normal wear and tear, for installation misalignment and for the correction of the saw-tooth condition as illustrated in Figure 5. It will also be noted that the upper and
lower hinge brackets door assembly 24 from thedoor frame 12. - Adjustment of the saw-tooth condition as illustrated in Figure 5 will be easily accomplished by swinging each of the
doors 24 to an open position, loosening the respectivemechanical fastener hinge brackets brackets door assemblies 24 within thedoor frame 12, and tightening themechanical fasteners - As noted, the design of the components of the subject door mounting arrangement provide an extremely desirable reversability feature. Refrigerated display cabinet door assemblies of the type described herein typically may be installed for hinging movement about either a right-hand or left-hand hinge axis, e.g., by simply inverting the panels. It will be observed that the hinge mounting arrangement of the subject invention easily provides for this in that each of the upper and
lower hinge brackets - As shown in Figure 2 in phantom, the
upper hinge bracket 46 needs merely to be rotated 180 degrees and fitted within hinge slot 62' ofweb portion 60 for providing a suitable adjustable hinge door mounting arrangement for doors which would open by swinging to the right. Similarly, thelower hinge bracket 48 may be shifted with respect tolower frame member 16 and fastened thereto by using fastener hole 81 and the additional hole 80'. The otherhinge pin slot 70 is used to receive the hinge pin for doors which swing open to the right. - Upper and
lower frame member slots 62 and 62', and fastener holes 80 and 80', respectively. In this way, selection of either right or left swinging movement may be made during installation depending on the specific requirements, and may be easily changed during the service life of the door structure if desired. Thus, the subject invention provides not only an adjustable door mounting arrangement for refrigerator display cabinets but is easily adaptable for door assemblies which are adapted to swing open either to the right or to the left. - From the foregoing, it will be observed that numerous variations and modifications may be effected without departing from the true spirit and scope of the novel concept of the subject invention. It will be understood that no limitations with respect to the specific apparatus illustrated herein is intended or should be inferred. It is, of course, intended to cover by the appended claims all such modifications as fall within the scope of the claims.
