Abstract

A nozzle assembly connectable to a pressure washer water output line that is adapted for cleaning curbs. The curb cleaner nozzle assembly includes multiple nozzles that are oriented at different angles and are adjustable by the user to the desired orientation to most effectively clean a particular curb. The nozzle assembly is mounted onto a wheeled support structure to allow the nozzle assembly to be moved along the curb while supporting the nozzles at the correct orientation and spacing for optimal cleaning of the curb.

Claims

1. A curb cleaner nozzle assembly comprising:

an adjustable height carriage assembly;

a dual nozzle spray head assembly rotatably connected to an upper deck plate of said carriage assembly; and

a flow control valve assembly with a valve body connected to said input of an input line of said dual nozzle spray head assembly and a spring loaded, valve control lever connected to said valve body with a shielded push/pull mechanical cable assembly;

said adjustable height carriage assembly having a substantially planar upper deck plate, a handle assembly extending from a rear end upper surface of said upper deck plate and a number of wheel assemblies mounted to said upper deck plate in a manner to rollably support said upper deck plate;

each wheel assembly including a height adjustment mechanism for allowing a user to adjust said height at which said wheel assembly supports said upper deck plate;

said dual nozzle spray head assembly including a single input pipe mounted to a nozzle orientation plate rotatably connected to an upper surface of said upper deck plate;

said 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;

said top nozzle and said side nozzle each being detachable, respectively, from said top nozzle supply pipe and said side nozzle supply pipe;

said top discharge orifice discharging water at a right angle to water discharged from said side discharge orifice;

said nozzle orientation plate being lockable in a desired position with respect to said upper deck plate with a rotating base locking pin;

said valve body having a flow control valve connected between a nozzle connector and a high pressure supply line connector;

said nozzle connector being in fluid flow connection with said input pipe of said nozzle assembly;

said flow control valve being controlled by said spring loaded, valve control lever;

said spring loaded valve control lever being mounted on said handle;

said spring loaded valve control lever being biased in a manner to move said spring loaded valve control lever away from said handle and to shut off flow through said flow control valve;

said flow control valve being opened by squeezing said spring loaded valve control lever towards said handle.
