Abstract: A user-propelled collapsible apparatus comprises a body (1) provided with wheels (21) and a retractable handle means (3) for propelling the apparatus. Bracing means (5) is provided for the handle means, the bracing means being movable between a deployed configuration in which the bracing means supports the extended handle means and a stored configuration in which the bracing means lies substantially adjacent to the body.

Abstract: A line marking apparatus comprises a housing (1) provided with wheels (3), means (5) for propelling the apparatus, and a spray head (9) for delivering line marking material to a surface to be marked. At least one line guide (11) is provided for defining an edge of a line to be marked, the line guide being mounted on an arm (15) which is pivotably mounted relative to the remainder of the apparatus such that the line guide is movable between a deployed configuration and a stored configuration in which the line guide is received in receiving structure (23) formed on the housing.

Abstract: A line marking apparatus includes a closed circuit circulation system for line marking material. The circulation system comprises a pump (17) for circulating line marking material under pressure through the circuit from an outlet of the pump back to an inlet thereof. The circulation system also comprises an inlet (15) for introducing fresh line marking material to the circuit when required, the inlet being positioned upstream of the inlet of the pump. The circulation system further comprises means (19, 25) for controlling the pressure of line marking material downstream of the outlet of the pump. The circulation system moreover comprises an outlet for conducting pressurized line marking material to a spray nozzle (21) for marking a line (23) with the line marking material when the fluid pressure in the circulation system exceeds a threshold.

Abstract: A line marking apparatus incorporates a replaceable container (31) of line marking material. The apparatus comprises a body (3) including an opening provided with a first engaging member (21), and a replaceable container (31) for line marking material. The container comprises a base (33) and side walls (35) and is provided with an outlet (37) for the line marking material at a location remote from the base. The container is also provided in the region of the base with a second engaging member (49) adapted to co-operate with the first engaging member of the body for releasably suspending the container within the body in an inverted configuration.
