摘要 An eyewash fountain especially useful in industrial and laboratory environments to provide a water discharge suitable for flushing irritants from the eyes of a workman. The fountain includes a bowl having a pair of upwardly and inwardly facing nozzles through which an eye-bathing flow of water can be discharged for so flushing the eyes of a workman. A valve connected in the water supply line controls the flow of water to the nozzles, and operating mechanism associated with the valve selectively opens and closes the same. The operating mechanism includes activators located along opposite sides of the bowl and essentially forming a part of the exterior surface thereof, and such activators can be operated to open the valve by a slight downward pressure as by leaning thereon with the hands, forearms, or elbows.
权利要求
1. An eyewash fountain or the like, comprising: a generally concave bowl having a drain opening adjacent the bottom thereof through which liquid is removed and having also a raised nozzle integral with said bowl within the concavity thereof and being oriented and positioned to provide an upwardly and inwardly directed stream of eye-flushing liquid, said raised nozzle projecting inwardly from the surface of said bowl and defining a relatively large chamber, flow passage means connected with said nozzle and large chamber to supply liquid thereto from a supply source, a control valve connected with said flow passage means for controlling liquid flow therethrough, perimetric frame structure bordering said bowl along the outer upper edges thereof and being fixedly secured thereto, said frame structure having a recess disposed in the outer upper surface thereof, a manually depressible push plate located within said recess and effectively defining a continuation of the adjacent surfaces of said frame structure and being displaceable with respect thereto between an outer inoperative position and an inner operative position, and linkage interconnecting said push plate and valve for operating the latter in response to displacements of the former.
2. The fountain of claim 1 in which said bowl is equipped with a Pair of said nozzles each integral with the bowl within the concavity thereof and being oriented and positioned to provide an upwardly and inwardly directed stream of eye-flushing liquid and being raised so as to project upwardly from the surface of the bowl and defining a relatively large chamber connected with said flow passage means, all as aforesaid.
3. The fountain of claim 1 in which said frame structure has a pair of the aforesaid recesses disposed in the outer surface thereof along opposite sides of said fountain, and a pair of push plates respectively disposed in said recesses and effectively defining a continuation of the adjacent surfaces of said frame structure and being displaceable with respect thereto between inoperative and operative positions, as aforesaid, said linkage interconnecting each of said push plates and valve for operating the latter in response to manual displacements of either of the former.
4. The fountain of claim 3 in which said bowl is equipped with a pair of said nozzles each integral with the bowl within the concavity thereof and being oriented and positioned to provide an upwardly and inwardly directed stream of eye-flushing liquid and being raised so as to project upwardly from the surface of the bowl and defining a relatively large chamber connected with said flow passage means, all as aforesaid.
