Title: Dispenser housing

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to housings, and more particularly but not by way of limitation, to a housing for use with a dispenser. 
     2. Description of the Related Art 
     A housing surrounds and improves the aesthetics of a soda and/or ice dispenser. Typically, the housing has pivotal panels and removable plates so that a repairman services the dispenser by lifting and bracing the panels or unscrewing the plates. 
     The use of these conventional dispenser housings suffers several disadvantages. Conventional housings, using parts such as screws or bolts, complicate the opening of the housing and training of repairmen. Opening conventional dispenser housings wastes time in locating suitable tools. Additionally, conventional dispenser housings, having detachable parts, require extra training of repairmen that potentially is unavailable in remote areas. 
     Another disadvantage with conventional housings is that detachable parts, such as screws and bolts, must be accounted for during servicing. These parts if missing must be replaced, otherwise the dispenser housing&#39;s stability may be jeopardized. 
     Yet another disadvantage of conventional housings is that the panel covering the dispenser valves does not pivot downward. The panel, failing to pivot downward, hinders accessibility of the valves during servicing. 
     An additional disadvantage of conventional housings is that the removable plates and pivotal panels are sometimes difficult to reach, causing a repairman to climb to the top of the housing to remove plates or open panels for accessing the dispenser. 
     A further disadvantage of some conventional housings is that the water and syrup adjusters are inaccessible unless a plate is detached by removing screws or bolts. 
     Accordingly, a housing having unfolding facial members will improve serviceability over conventional housings. 
     SUMMARY OF THE INVENTION 
     In accordance with the aims of the present invention, one embodiment of a dispenser housing includes a face. The face has a valve casing pivotally extendable to provide access to the valves of a soda dispenser. 
     Another embodiment of the present invention is a jointed connection for a valve casing of a soda dispenser housing. The jointed connection includes at least one valve casing joint having a plate, a lever, and a pin. The plate has a plurality of legs extending therefrom wherein each of the legs has an aperture therethrough. The lever is insertable through the apertures. The pin is releasably engageable with the lever to permit longitudinal and pivotal movement of the valve casing. 
     An additional embodiment of the present invention is a dispenser unit. The dispenser unit includes a soda dispenser and a housing. The soda dispenser has at least one valve and one switch. The housing has a face which, in turn, includes a first access member pivotally movable between a first position and a second position to provide access to the soda dispenser, and a valve casing being longitudinally and pivotally extendable to provide access to the valve of the soda dispenser. The valve casing has an aperture access member and covering. The aperture access member and covering each have at least one aperture. The aperture access member is positionable to align the aperture of the aperture access member with the aperture of the covering. 
     It is, therefore, an object of the present invention to provide a housing that protects a dispenser. 
     Another object of the present invention is to provide an easily opened housing without utilizing removable fastening members. 
     A further object of the present invention is to provide an invention having casing members that are connected without the use of fastening members. 
     Another object of the present invention is to provide a housing having access openings to the dispenser valves for adjusting the water and syrup flow rates. 
     An additional object of the present invention is to provide an aperture access cover for permitting opening and closing of the valve adjustment apertures.

Preferably supports 62a-b are either stainless steel lift supports, part #11615A11, distributed by the McMaster Car Supply Company, 6100 Fulton Industrial Boulevard, Atlanta, Ga. 30336 or piston supports marketed under the tradename LIFT-O-MAT, Part #FJN344 0140N, manufactured by Stabious, 92 County Line Road, Colmar, Pa. 18915. Lifting and locking first access member 60 in second position 60b permit inspection of second access member 70 and light sources 74a-b, which are preferably florescent lights. 
     Second access member 70 is pivotally movable between a first substantially vertical position 70a and a second substantially horizontal position 70b. Brackets 71a-b mount second access member 70 to brace 51 and supports 72a-b, secured to brace 51 and second access member 70, permit locking and releasing of second access member 70 in second position 70b. Preferably supports 72a-b are either stainless steel lift supports or piston supports as previously described. Lifting and locking second access member 70 in second position 70b permit inspection of soda dispenser 53, including carbonator pump, carbonator motor, ice probes, carbonator probe, transformer reset, relief valve, and electronics; ice dispenser 56; and housing 10, including light mounts. In position 70b, light sources 74a-b remain electrically connected to an electrical source thereby illuminating dispensers 53 and 56 within housing 10. 
     Valve casing or third access member 80 extends outwardly to a first partially opened position 80a and is downwardly pivotal to a second position 80b, thereby permitting inspection of valves 120a-f. Valve casing 80 includes internal support 85, covering 86, and aperture access member 90. Internal support 85 includes an elongated substantially rectangular bar 185, arms 186a-b, and apertures 189a-g. Each arm 186a-b is welded to an end of bar 185. Covering 86 includes holes 199a-g and a body 196. Body 196, having a protruding lip 197 and slot 200, is integrally formed with arms 198a-b. Aligning holes 199a-g with apertures 189a-g allows the insertion of securing members, such as screws, for mounting covering 86 over support 85 to form a single unit. 
     A brace 84 and valve casing joints 95a-b anchor valve casing 80 to first casing member 20 and third casing member 40. Brace 84 includes an elongated rectangular flat plate 174 integrally formed with substantially rectangular arms 175a-b. Plate 174 includes openings 179a-f for inserting dispenser 53 outlet nozzles therethrough. Each arm 175a-b has a respective slot 87a-b extending therethrough and holes 180a-d. Aligning holes 180a-b of arm 175a with apertures 22a-b of first casing member 20 and holes 180c-d of arm 175b with apertures 42a-b of third casing member 40 permits attaching brace 84 to first casing member 20 and third casing member 40 with securing members, such as screws. 
     Joints 95a-b provide an extendable connection between brace 84 and valve casing 80. Joints 95a-b are substantially identical, therefore, only joint 95a will be described in detail hereinafter. Joint 95a includes a plate 100a, first securing member 104a, second securing member 105a, pin 107a, and lever 110a. Securing members 104a and 105a, preferably screws, mount plate 100a to arm 175a of brace 84. Plate 100a is substantially perpendicular to and formed integrally with legs 101a and 102a. Lever 110a is insertable through apertures 108a and 109a of legs 101a and 102a, respectively. Lever 110a, having a substantially inverted L-shape, is formed integrally with upwardly extending arm 112a. A bottom edge 113a of lever 110a forms a generally acute angle with a side edge 114a. Pin 107a extends through slot 87a of brace 84 and connects to internal support 85 of valve casing 80. 
     Pulling upwardly on levers 110a-b opens valve casing 80 by positioning bottom edges 113a-b above pins 107a-b. Pulling outwardly on valve casing 80 moves internal support 85 and covering 87 away from brace 84. Pin 107a slides along the length of slot 87a until it reaches outer edge 88a of slot 87a, resulting in valve casing 80 being moved to first position 80a. Rotating downwardly positions valve casing 80 in second position 80b, thereby permitting access to valves 120a-f of dispenser 10. 
     Rotating upwardly to first position 80a and then pushing inwardly towards dispenser 53 closes valve casing 80. After rotating upwardly, pushing inwardly slides pin 107a toward inner edge 89a of slot 87a. As pin 107a engages bottom edge 113a, it moves lever 110a upward. After pin 107a reaches the inner edge 89a of slot 87a, lever 110a falls downwardly to lock pin 107a and valve casing 80. 
     Aperture access member 90 of valve casing 80, positioned between internal support 85 and cover 86, permits access to valve adjustments 122a-f of valves 120a-f for altering syrup and water flow rates. Each valve 120a-f has one outlet for syrup and the other for carbonated or uncarbonated water and corresponding adjustments 122a-f for adjusting the ratio of syrup to water. Aperture access 90 has apertures 92a-l and knob 94, which protrudes through slot 200 of covering 86. Moving knob 94 toward end 202 of slot 200, as shown in FIG. 6b, aligns apertures 92a-l with valve adjustment apertures 82a-l of covering 86. This alignment permits adjusting the syrup and water with a screwdriver by inserting the screwdriver through apertures 82a-l and apertures 92a-l into valve adjustments 122a-f. When the servicing is completed, sliding knob 94 toward end 201 of slot 200 offsets apertures 82a-l and apertures 92a-l as shown in FIG. 6a.
