ABSTRACT:
TECHNICAL FIELD
The present invention relates to cleaning equipment and more particularly to a curb cleaner nozzle assembly that includes an adjustable height carriage assembly, a dual nozzle spray head assembly rotatably connected to an upper deck plate of the carriage assembly, and a flow control valve assembly with the valve body connected to the input of the input line of the dual nozzle spray head assembly and the spring loaded, valve control lever connected to the valve body with a shielded push/pull mechanical cable assembly; the adjustable height carriage assembly having a substantially planar upper deck plate, a handle assembly extending from a rear end upper surface of the upper deck plate and a number of wheel assemblies mounted to the upper deck plate in a manner to rollably support the upper deck plate; each wheel assembly including a height adjustment mechanism for allowing a user to adjust the height at which the wheel assembly supports the upper deck plate; the dual nozzle spray head assembly including a single input pipe mounted to nozzle orientation plate rotatably connected to an upper surface of the upper deck plate; the single input pipe being in fluid flow connection with a top nozzle supply pipe terminating in a top nozzle having a top discharge orifice and a side nozzle supply pipe terminating in a side nozzle have a side discharge orifice; the top nozzle and the side nozzle each being detachable, respectively, from the top nozzle supply pie and the side nozzle supply pipe; the top discharge orifice discharging water at a right angle to water discharged from the side discharge orifice; the nozzle orientation plate being lockable in a desired position with respect to the upper deck plate with a rotating base locking pin; the valve body having a flow control valve connected between a nozzle connector and a high pressure supply line connector; the nozzle connector being in fluid flow connection with the input pipe of the nozzle assembly; the flow control valve being controlled by the spring loaded, valve control lever; the spring loaded valve control lever being mounted on the handle; the spring loaded valve control lever being biased in a manner to move the spring loaded valve control lever away from the handle and to shut off flow through the flow control valve; the flow control valve being opened by squeezing the spring loaded valve control lever towards the handle.
BACKGROUND ART
Clean curbs greatly enhance the overall appearance of areas such as businesses, gardens, and the like. Although clean curbs are desirable, it can be difficult to quickly and easily clean them because curbs typically have multiple surfaces oriented at angles with respect to each other. It would be desirable, therefore, to have a curb cleaner that included multiple nozzles that were oriented at different angles and adjustable by the user to the desired orientation. Because maintaining the cleaning nozzles at the proper and distance can be difficult. It would be a further benefit to have a curb cleaner that included a wheeled support structure for supporting the nozzles at the correct orientation and spacing for optimal cleaning of the curb and that could be pushed along the curb to be cleaned.
GENERAL SUMMARY DISCUSSION OF INVENTION
It is thus an object of the invention to provide a curb cleaner nozzle assembly that includes an adjustable height carriage assembly, a dual nozzle spray head assembly rotatably connected to an upper deck plate of the carriage assembly, and a flow control valve assembly with the valve body connected to the input of the input line of the dual nozzle spray head assembly and the spring loaded, valve control lever connected to the valve body with a shielded push/pull mechanical cable assembly; the adjustable height carriage assembly having a substantially planar upper deck plate, a handle assembly extending from a rear end upper surface of the upper deck plate and a number of wheel assemblies mounted to the upper deck plate in a manner to rollably support the upper deck plate; each wheel assembly including a height adjustment mechanism for allowing a user to adjust the height at which the wheel assembly supports the upper deck plate; the dual nozzle spray head assembly including a single input pipe mounted to nozzle orientation plate rotatably connected to an upper surface of the upper deck plate; the single input pipe being in fluid flow connection with a top nozzle supply pipe terminating in a top nozzle having a top discharge orifice and a side nozzle supply pipe terminating in a side nozzle have a side discharge orifice; the top nozzle and the side nozzle each being detachable, respectively, from the top nozzle supply pie and the side nozzle supply pipe; the top discharge orifice discharging water at a right angle to water discharged from the side discharge orifice; the nozzle orientation plate being lockable in a desired position with respect to the upper deck plate with a rotating base locking pin; the valve body having a flow control valve connected between a nozzle connector and a high pressure supply line connector; the nozzle connector being in fluid flow connection with the input pipe of the nozzle assembly; the flow control valve being controlled by the spring loaded, valve control lever; the spring loaded valve control lever being mounted on the handle; the spring loaded valve control lever being biased in a manner to move the spring loaded valve control lever away from the handle and to shut off flow through the flow control valve; the flow control valve being opened by squeezing the spring loaded valve control lever towards the handle.
Accordingly, a curb cleaner nozzle assembly is provided. The curb cleaner nozzle assembly includes an adjustable height carriage assembly, a dual nozzle spray head assembly rotatably connected to an upper deck plate of the carriage assembly, and a flow control valve assembly with the valve body connected to the input of the input line of the dual nozzle spray head assembly and the spring loaded, valve control lever connected to the valve body with a shielded push/pull mechanical cable assembly; the adjustable height carriage assembly having a substantially planar upper deck plate, a handle assembly extending from a rear end upper surface of the upper deck plate and a number of wheel assemblies mounted to the upper deck plate in a manner to rollably support the upper deck plate; each wheel assembly including a height adjustment mechanism for allowing a user to adjust the height at which the wheel assembly supports the upper deck plate; the dual nozzle spray head assembly including a single input pipe mounted to nozzle orientation plate rotatably connected to an upper surface of the upper deck plate; the single input pipe being in fluid flow connection with a top nozzle supply pipe terminating in a top nozzle having a top discharge orifice and a side nozzle supply pipe terminating in a side nozzle have a side discharge orifice; the top nozzle and the side nozzle each being detachable, respectively, from the top nozzle supply pie and the side nozzle supply pipe; the top discharge orifice discharging water at a right angle to water discharged from the side discharge orifice; the nozzle orientation plate being lockable in a desired position with respect to the upper deck plate with a rotating base locking pin; the valve body having a flow control valve connected between a nozzle connector and a high pressure supply line connector; the nozzle connector being in fluid flow connection with the input pipe of the nozzle assembly; the flow control valve being controlled by the spring loaded, valve control lever; the spring loaded valve control lever being mounted on the handle; the spring loaded valve control lever being biased in a manner to move the spring loaded valve control lever away from the handle and to shut off flow through the flow control valve; the flow control valve being opened by squeezing the spring loaded valve control lever towards the handle.
