It is an object of the present invention to provide a sliding panel assembly for providing access to a through-the-doorservice'area in a refrigerator cabinet or the like including a pair of panels, one of which is slidable such that the panels are positioned in side-byside relationship so as to provide a smooth and uninterrupted appearance with the refrigerator door outer shell when the panel is in its closed position; and means for guiding followers on the slidable panel rearwardly and behind the fixed panel by means of first track grooves outwardly and rearwardly pitched from inner offset end portions and second track grooves substantially aligned with the offset portions of the first track grooves.
Further objects and advantages of the present invention will be apparent from the following description,
reference being had to the accompanying drawings wherein a preferred embodiment of the present invention is clearly shown.
In the Drawings:
FIG. I is a perspective view of a refrigerator cabinet the line 33 of FIG. 2;
FIG. 4 is an enlarged sectional view of the door top plate taken on line 4-4 of FIG. 2;
FIG. 5 is an enlarged sectional view taken on the line 5-5 of FIG. 2;
FIG. 6 is an enlarged sectional view of the panel door lower support taken on the line 66 of FIG. 2.
Referring now to the drawings, there is shown in FIG. I a refrigerator cabinet 10 having an upper freezer compartment closed by an upper insulated access door 11 and a lower fresh food compartment closed by a lower insulated access door 12. While it is understood that the instant invention may be used on different door or cabinet structures, the disclosed doors are of the wing" design disclosed in U.S. Pat. No. 3,314,196 issued Apr. 18, I967, to the same assignee as the present invention, wherein one or both of the left and right hand structural side members 13 and 14 respectively, are shaped to serve as a handle for opening the door. The lower access door 12 includes an outer shell or wall 16 having a recessed compartment or service area 18 therein which in the disclosed form provides a combined through-the-door ice cube, water and beverage concentrate dispensing area such that a suitable receptacle such as glass 20 may be positioned on the shelf of the service area for receiving ice cubes by depressing actuator 21 and either chilled water or a beverage concentrate by depressing suitable button 22. The ice cube dispensing portion of the service area is shown and described in copending U.S. patent application Ser. No. 309,935 now US. Pat. No. 3,789,620 assigned to the assignee of the instant application, the disclosure of which is incorporated by reference herein.
As seen in FIG. 2, the service area I8 has a rectangular configuration and extends from the left hand side member 13 of the lower refrigerator door 12 to a point approximately midway between the side members 13 and 14 of the door. The service area 18 is bounded on its upper end by a laterally extending door top plate 30 including upper rail member 32 which caps the upper edge of the lower door 12. The lower boundary of the service area 18 is defined by a lower rail member 34 coextensive with the upper rail member 32 and parallel therewith.
With reference to FIG. 1, a panel assembly is shown including a pair of rectangular panels 36' and 38 which are mounted between the upper and lower rail members 32 and 34. The first fixed panel 36 is located on the right hand side of the door while the second panel 38 is movably positioned in side-by-side relationship with the first fixed panel 36 and is operative for closing the service area 1 8 by moving the second sliding panel I 38 from its open position underlying the fixed panel 36 to its closed position of FIG. 2 where panel 38 is located substantially flush with the outer shell 16 of the refrigerator door. In the preferred embodiment the first and second panels are formed of plastic material such as Plexiglas having a thickness of the order of 0.125 inches and appropriately colored such as by a bronze tint.
The track configuration on the upper and lower rails are formed in an identical mirror imagemanner for supporting the movable panel 38 and accordingly only the track configuration of the upper rail 32 will be described in detail. As seen in FIG. 3, integral groove means 40 are provided on the undersurface of the upper rail 32 for retaining the upper edge of the right hand plastic panel 36, with a matching groove on lower rail 34, such that panel 36 is held in fixed relation adjacent the front edge of the rail members. The track configuration includes first and second upper track grooves indicated at 42 and 44 respectively, in FIG. 3.
Inner 52 and outer 54 pairs of pins are carried on the upper and lower edges of the left hand movable panel 38 and adjacent the end thereof are adapted for sliding movement in the first 42 and second 44 tracks, respectively, by means of pins 52 and 54. As seen in FIG. 2, the stems 55 of outer pins 54 are positioned atthe top and bottom of the movable panel 38 and adjacent the outer edge 57 thereof with their stem portion 55 positioned in apertures or bores in the panel allowing their enlarged heads to be received in the upper and lower second tracks 44 for sliding movement therein. The panel 38, which is shown outwardly curved in FIG. 5 to conform with shell 16, has a thickened peripheral edge strip 58 including corner blocks 59 on the inner face thereof providing bores for mounting the stems 55 of the pins therein.
As best seen in FIG. 5, the movable panel 38 is provided with an inwardly offset integral flange 60 located at its inner vertical edge 62 and coextensive therewith. In the disclosed form the offset flange 60 has a thick in thickness such that the overall front to back dimension of panel 38 is about 0.250 inches. The inner pins 52 are similarly located adjacent the free edge 56 of the offset flange 60 with their shank portions inserted in integrally molded bores in the vertical edge strip65 of flange 60 with the heads of the pins dimensioned to be slidably received in the upper and lower first tracks 42.
As seen in FIG. 3, the first upper main track 42 has a diagonal or dog-leg end portion 66 forming an angle of about 45 with the closed offset flange 60 and forwardly offset portion 67 substantially parallel to the closed position of offset flange 60. It will be noted that the second track groove 44 extends inwardly and forwardly from the door left hand side member 13 at a pitched angle A of about 2 so as to be in substantial alignment with the offset portion 67. it will also be noted that the track grooves 44 and 44' are substantially coextensive with the opening of the service area or chamber 18 so as to extend just beyond the inner side wall 69.
In this way when the movable panel 38 is in its closed position, the outer pins 54 engage the end 74 of the second track 44 terminating the sliding movement of the panel 38 before inner pins 52 contact the end 76 of offset parallel portions 67 of tracks 42, thereby locating the fixed and movablepair of panels in side-by-side relationship. This closed panel arrangement provides a defined vertically extending space 78 between the panel inner edges 62 and 72 such that the inwardly offset flange 60 is coextensive with space 78 so as to underlie the fixed panel inner edge 72 and provide an uninterrupted frontal coverage appearance by the panels.
lnitial sliding movement of the movable panel 38 by means of pressure exerted inwardly on the handle member 80 causes the inner pins 52 to move from the offset track portion 67 through the 45 diagonal track .portion 66 to kick-away or clear the panel edge 62 from the fixed panel edge 72. The diagonal track portion makes connection with first main track section 42 which extends in substantially parallel relation to groove means 40 for locating panel 38 in spaced inward relation behind the fixed panel 36. By virtue of the first main track 42 being pitched inwardly and rearwardly at an angle B of about 5 with respect to an imaginary vertical transverse plane it will be seen that the outer face 64 of the panel 38 is caused to keep falling away from the fixed edge 72 to enable the panel 38 to be moved rearwardly and behind the fixed panel 36. During closing of the movable panel 38 the reverse action takes place with the pitched track grooves 44 acting to smoothly slide the inner pins 52 back through the offset track groove portions 66 and 67.
While the embodiment of the present invention constitutes a preferred form. it is to be understood that other forms might be adopted.
