Abstract
Abstract A rotatable spray head is disclosed wherein the spray head is received in a housing designed for mounting flush with a floor or other surface. A fluid supply line passes into the housing and is associated with the spray head in a telescoping fashion. The spray head is provided with a plurality of radially, outwardly extending fluid passageways, the outer ends of which are angularly varied so as to permit fluid to pass therethrough, cause the head to rotate and permit fluid to exit at different angles for complete coverage of an area being sprayed. The spray plate also serves as a cover for the receptacle and moves upwardly therefrom to a spray position when fluid pressure is applied to the underside thereof. In this regard, once the fluid pressure ceases, the spray head automatically returns to an inoperative position where it serves as a cover for the housing. Plate return to the inoperative position may be by gravity, by bias of a spring provided therefor or the like. A preferred embodiment of the present invention finds the housing also serving as a fluid drain and adapted to be connected to a drain line. In this embodiment, the spray plate is provided with a plurality of openings therein in direct communication with the drain so as to permit fluid that has been sprayed or otherwise deposited in the area to flow through the openings in the spray plate into the drain line.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
134 words
An improved fluid dispensing system comprising: a. a housing, said housing being adapted for connection to a fluid drain line; b. a fluid supply line associated with said housing and extending inwardly thereof; and c. a rotatable spray head received in said housing, said spray head comprising a stem and a spray plate secured thereto, said stem having an axial opening therethrough and in communication with said fluid line, said plate having a plurality of tortuous fluid passageways extending radially outwardly with respect thereto, said passageways being in communication with said axial opening, said spray head being movable to an operative position by a fluid force thereon and returnable to an inoperative position upon cessation of said fluid force, said spray plate further defining a plurality of drain openings dispersed between the fluid passageways.
Claim 2
Dependent Claim
134 words
An improved fluid dispensing system comprising: a. a housing, said housing being adapted for connection to a fluid drain line; b. a fluid supply line associated with said housing and extending inwardly thereof; and c. a rotatable spray head received in said housing, said spray head comprising a stem and a spray plate secured thereto, said stem having an axial opening therethrough and in communication with said fluid line, said plate having a plurality of tortuous fluid passageways extending radially outwardly with respect thereto, said passageways being in communication with said axial opening, said spray head being movable to an operative position by a fluid force thereon and returnable to an inoperative position upon cessation of said fluid force, said spray plate further defining a plurality of drain openings dispersed between the fluid passageways.
Claim 3
Dependent Claim
20 words
An improved fluid dispensing system as defined in claim 1 wherein said fluid supply line is integral with said housing.
Claim 4
Dependent Claim
38 words
An improved fluid dispensing system as defined in claim 1 wherein said fluid supply line and said stem are telescopingly associated for rotational and limited axial movement of said spray head with respect to said fluid supply line.
Claim 5
Dependent Claim
22 words
An improved fluid dispensing system as defined in claim 1 wherein said rotatable plate nests within said housing in an inoperative position.
Claim 6
Dependent Claim
27 words
An improved fluid dispensing system as defined in claim 4 wherein spring means are received around said stem to bias said spray head in the inoperative position.
Claim 7
Dependent Claim
22 words
An improved fluid dispensing system as defined in claim 1 wherein certain of said fluid passageways are dissimilar at their outer ends.
Claim 8
Dependent Claim
32 words
An improved fluid dispensing system as defined in claim 6 wherein deflection plates are provided at the outer ends of said fluid passageways to deflect fluid being dispensed in a predetermined direction.
Claim 9
Dependent Claim
31 words
An improved fluid dispensing system as defined in claim 1 wherein said fluid passageways terminate as deflection plates and wherein said deflection plates are varied to deflect fluid at predetermined angles.
Claim 10
Dependent Claim
119 words
An improved fluid dispensing system comprising: a. a housing, said housing having means thereon for connection to a drain line; b. a fluid supply line extending inwardly of said housing through a portion thereof; c. a spray nozzle received within said housing and in communication with said fluid supply line; and d. a cover received in said housing and completely enclosing same, said cover being attached to said nozzle whereby said cover and said nozzle move upwardly upon receipt of fluid pressure thereon and return to an inoperative position upon cessation of fluid pressure thereon, said cover further defining a plurality of drain openings disposed thereabout, whereby fluid may pass therethrough when said cover is in the inoperative position.
Claim 11
Dependent Claim
119 words
An improved fluid dispensing system comprising: a. a housing, said housing having means thereon for connection to a drain line; b. a fluid supply line extending inwardly of said housing through a portion thereof; c. a spray nozzle received within said housing and in communication with said fluid supply line; and d. a cover received in said housing and completely enclosing same, said cover being attached to said nozzle whereby said cover and said nozzle move upwardly upon receipt of fluid pressure thereon and return to an inoperative position upon cessation of fluid pressure thereon, said cover further defining a plurality of drain openings disposed thereabout, whereby fluid may pass therethrough when said cover is in the inoperative position.
Claim 12
Dependent Claim
110 words
An improved fluid dispensing system comprising: a. a housing, said housing having means thereon for connection to a fluid drain line; b. a fluid supply line associated with said housing and extending inwardly thereof; and c. a rotatable fluid dispensing plate operatively associated with said fluid supply line and said housing, said plate having a plurality of fluid passageways disposed thereabout and in communication with said fluid supply line, said spray plate further having a plurality of drain openings disposed between the fluid passageways, said spray plate being movable to an operative position by a fluid force thereon and returnable to an inoperative position upon cessation of said fluid force.
Claim 13
Dependent Claim
110 words
