Barthel [5 7] ABSTRACT 5 Claims, 6 Drawing Figures WATERLINE RETRACTOR FOR REFRIGERATOR CABINET This invention relates to a domestic refrigerator and particularly to a refrigerator having a cold water dispensing arangement which allows the extension and retraction of a flexible water line associated with the cabinet into a door hingedly secured thereto.
An object of this invention is to provide a means on a refrigerator cabinet having an exterior cold water service area located on the exterior surface of the refrigerator door which allows the water line communicating with a cooling tank within the refrigerator cabinet and leading therefrom into the door to slide into and out of the door upon the closing and opening thereof and thereby reduce bending or flexing of the water line at the point the line is directed into the door to thereby increase the life of the water line.
A further object of this invention is to provide a yieldably biased reel member positioned on the side wall of a refrigerator cabinet such that a water line leading from a cooling tank within the cabinet to a service area within the refrigerator door is received around the reel in a serpentine fashion so as to pivot the reel with respect to the cabinet when the door is open for minimizing bending and flexing of the water line during movement of the door and which retracts the water line for return movement into the refrigerator cabinet upon the door being returned to its closed position.
Further objects and advantages will become more apparent from the following specification, reference being had to the accompanying drawings of which:
FIG. 1 is a perspective view of a refrigerator cabinet incorporating the present invention with the lower compartment door shown in an open position;
FIG. 2 is a front elevational view of the water line re- I tractor located in the refrigerator compartment;
FIG. 3 is a sectional view taken on the line 33 of FIG. 2;

FIG. 5 is a fragmentary sectional view taken on the line 5-5 of FIG. 4;
FIG. 6 is a fragmentary front view of the door service area.
Referring now to the drawings, there is shown in FIG. 1 a refrigerator cabinet 10 having an upper freezing compartment enclosed by an upper door 11 and a lower fresh food storage compartment 12. The cabinet includes an insulated top outer wall 13, insulated side walls 14 and 15, the inner surfaces of which extend rearwardly from the cabinet front opening, and having disposed therebetween in the lower compartment a plurality of shelves 1'6 and lower storage pans 17 and 18 located above compartment insulated bottom wall 19. The lower fresh food compartment 12 has an access opening 20 thereto closedby a lower insulated door 22. The lower door 22 includes an outer sheet metal wall 24 having a water service area 25 provided in the face of the door. Such a service areais shown and described in co-pending U.S. Pat. application Ser. No. 309,935 assigned to the assignee of the instant application, the disclosure of which is incorporated by reference herein.
The door 22 is provided with an inner door pan 26 preferably of sheet plastic material such as high impact polystyrene or ABS copolymer. The door pan 26 is bordered by a peripheral rib 27 having shelves 28 extending between the vertical portions of the rib. The inside of the door 22 includes an enclosure 30 positioned opposite the service area for enclosing portions of water dispensing means such as, for example, the dispensing unit disclosed in U.S. Pat. No. 2,786,338 issued Mar. 26, 1957 to C. H. Wurtz et al. and assigned to the same assignee as the instant application.
As seen in FIG. 1, a water coller receptacle tank for supplying cold water to the service area is positioned in the rear portion of the fresh food compartment 12 and generally indicated by the numeral 32 is connected through a solenoid operated valve 33 to a high pressure water supply line 34. The control valve is located in the machine compartment of the refrigerator and is acutuated in response to the energization and deenergization of an electric solenoid 35 associated therewith. The water tank 32 is exposed to the low temperature within the food compartment so as to be effectively cooled thereby.
A pipe 37 extends upwardly in the cabinet from the control valve 35 to the underside of the tank 32. A conduit cover 38 on the back wall of the compartment 12 encloses a length of tubing 39 which connects the tank 32 to a manually actuated selector valve 23 and nozzle 28 in the exterior service area 25 on the door of the type disclosed in the Wurtz et al patent. As seen in FIG. 2 a length of the tubing 39 exits the conduit and extends through a retractor unit 40 secured on the side wall 15 of the cabinet adjacent the front access opening 20 adjacent the hinged edge of the door 22. The tube 39 is a readily mobile or flexible member preferably constructed of plastic or rubber-like material having an outer diameter of about 0.25 inches in the disclosed form. Within the retractorunit 40 the flexible tube 39 is formed into a double-looped or serpentine configuration oriented in a common vertical plane parallel to the side wall 15.
The water line retractor unit 40 includes a housing cover 42 and base plate 44 made of any suitable material, for example impact polystyrene plastic, and constructed in any suitable manner, for example, by molding. The cover comprises an outer wall 45, opposed front 46 and rear 47 walls and bottom wall 48, and is secured to the base plate 44 by suitable threaded screws indicated at 52 received in integrally molded threaded embossments such as shown at 53 in FIGS. 2 and '3. The base plate 44 is secured as at 54 to the cabinet wall 15 so as to be removably attached thereto. The
face of the base plate 44 includes first threading means forming a first loop of the tubing 39 including a plurality of integrally molded arcuate guides 56, 57 and 58 and a semi-circular guide 72 between which the first loop of the flexible tube 39 is threaded in its initial pass 39a into the retractor unit 40 through lower opening 59 in rear wall 47.
Second threading means including a retractor reel 60, preferably molded of nylon plastic, is rotatbly mounted on a transverse pivot pin 62 formed on'the upper end of a pivoting straight tangential arm portion 64 of yieldable means in the form of a wire coiled torsion spring body 66 telescoped over the integrally molded drum 67 such that the axis of its coiled body portion is perpendicular to base plate 44. The coiled body 66 extends into a hooked arm 68 at its inner axial end transverse to the axis of the coiled spring body 66 so as to be anchored around integrally molded base plate peg 69. The coiled body 66 extends into the arm 64 at its outer axial end transverse to the axis of the coiled spring body 66. In this manner the reel 60 is normally resiliently biased in a retracted position inwardly or towards the rear wall 47 of the cover 42, as viewed in dashed lines in FIG. 2, so that the reel is continuously urged in its retracted dashed line position by the torsion spring body 66.
As viewed in FIG. 2 the first loop of the tube 39 is threaded around the semi-circular guide 72, adjacent front wall 46, through an angle of about 200 with respect to its return pass portion 39b within the retractor unit. The second loop of the tube is threaded in peripheral groove 74 of the reel 60 through an angle of about 200 with respect to the tubes final return pass 390 which is slidably received within a longitudinally extending guide bushing 78 postioned at the forward end of unit 40. The guide bushing 78, preferably formed of plastic material such as nylon, is disposed in an opening 76 in the cover front wall 46 and is secured to the cabinet side wall by screws 77. Slidably movable within the guide bushings' axial bore 79 is a length of the tube 39 including a predetermined length of the tube disposed intermediate the cabinet and the door which is enclosed by a flexible tube sheath in the form of helical coil spring 80 which is dimensioned for smooth slidable movement in the bore 79.
As seen in FIGS. 4 and an opening 82 is provided in the door pan upper rib portion 27 for reception of a bifurcated C-clamp member 84, preferably formed of nylon, having a counterbored portion 86 therein aligned with opening 82. A hat-shaped bushing 90 preferably of impact polystyrene material, is telescoped within the bore 86 and is provided with a plurality of longitudinal slots 92, there being three equally spaced slots in the form shown. The c-clamp bifurcated ends 93 and 94 are apertured for reception of threades machine screw 96 such that upon the end of coil 80 being seated in bore 86, with the tube portion 39d extending through clamp opening 97 and bushing opening 98 to pass within the door, the screw 96 is tightened about the slotted bushing 90 allowing the sheath 80 and tube 39 to be clamped therein.
Thus, in operation when the door 22 is opened the tube 39 being clamped or anchored at its entrance into the door pulls, by means of its second loop portion, upon the reel 60 causing the reel 60 to be pivoted foward to its solid line position of FIG. 2 which corresponds to the door being moved through an arc of about 90. A predetermined length of the sheathed portion of the tubes second loop is slidably withdrawn through the guide bushing of the retractor unit 40 by moving about the freely rotatable reel 60. The reel may be pulled forwardly in pivotal fashion about the axis of the coiled torsion spring permitting rotation of the door to an open position through an arc of at least 180 degreees or any lesser are such that the proper withdrawn sheathed tube length is achieved. As the door is subsequently moved to its closed position, the tension spring pivots the reel to its normal retracted position and retracts a portionof the sheathed tube through the guide bushing 78 into the retractor unit 40 to prevent or obviate crimping of the tube.
