DESCRIPTION:
BRIEF SUMMARY
The present invention relates to line marking apparatus which incorporates a line marking head for marking a line on a ground surface, the apparatus comprising a vehicle for movement across the ground surface to which the line marking head is connected. The invention is particularly, but not exclusively, concerned with the use of a line marking apparatus comprising a wheeled vehicle having a power source such as an internal combustion engine for driving some or all of the wheels of the vehicle.
Line marking heads hitherto connected to line marking vehicles have suffered the drawback that they have required the vehicle to be manoeuvred from the path taken thereby for generating a line on a ground surface when an obstacle is encountered on the axis of the line to enable the line marking head to be repositioned on the downstream side of the obstacle. Examples of such obstacles are goal posts on the boundary lines of football and rugby pitches.
It is the aim of the invention to provide means for enabling a line marking vehicle to pass an obstruction on the axis of a line being marked without the vehicle having to be deflected from its direction of travel for marking the line.
According to the present invention there is therefore provided a line marking apparatus comprising a vehicle for movement across a ground surface to be marked with a line, an outrigger structure connected to the vehicle, and a line marking head connected to the outrigger structure, the outrigger structure being movable between a first position in which the line marking head is deployed at an operational position which is offset to a side of the vehicle outside the bounds of the vehicle and a second position in which the line marking head is deployed at a retracted position located inwardly of the operational position relative to the vehicle, wherein the outrigger structure is pivotably mounted on the vehicle so as to be movable between the first and second positions in a plane which is perpendicular or substantially perpendicular to the ground surface and so as to cause the line marking head to move in a plane perpendicular or substantially perpendicular to the direction of movement of the vehicle on the ground surface.
In an embodiment of the invention hereinafter to be described the outrigger structure adopts an expanded configuration in its first position and a contracted configuration in its second position.
In an embodiment of the invention hereinafter to be described the outrigger structure comprises a plurality of interconnecting arms which define a parallelogram linkage for moving the outrigger structure between the first and second positions with the arms of the parallelogram linkage extending in a plane substantially perpendicular to the direction of movement of the vehicle. For ease of construction the arms of the parallelogram linkage can extend in the plane of retraction of the line marking head.
In an embodiment of the invention hereinafter to be described securing means are provided for releasably securing the outrigger structure in the first and second positions. For example, the securing means can comprise a spring.
In an embodiment of the invention hereinafter to be described the outrigger structure is manually actuatable to move it between the first and second positions.
In an embodiment of the invention hereinafter to be described the line marking head is disposed within the bounds of the vehicle when in its retracted position.
In an embodiment of the invention hereinafter to be described the line marking head contacts the ground surface when in its operational position. To facilitate movement across the ground surface the line marking head can be pivotally connected to the outrigger structure.
In an embodiment of the invention hereinafter to be described the line marking head has an outer cover member comprising a pair of spaced apart side walls which extend in a direction substantially parallel to the direction of travel of the vehicle to define a line marking channel and a transverse wall portion which connects the
