User-propelled collapsible apparatus

1. A user-propelled collapsible apparatus comprising: a body provided with wheels and components for dispensing line marking material, and a retractable handle for propelling the apparatus; wherein the apparatus is a line-marking apparatus, the body includes a housing for the components for dispensing line marking material and the handle is telescopically retractable substantially into the housing.

2. The apparatus of claim 1 , comprising bracing means for the handle, the bracing means being movable between a deployed configuration in which the bracing means supports the extended handle and a stored configuration in which the bracing means lies substantially adjacent to the body, wherein the bracing means comprises a cross-brace which, in the deployed configuration thereof, links two shafts of the handle together.

3. The apparatus of claim 2 , wherein the cross-brace is mounted on two arms, one arm being provided in the region of each side of the body and being mounted for pivoting relative to the body about a pivot point at that end of the arm remote from the cross-brace.

4. The apparatus of claim 3 , wherein the free ends of the arms are interconnected by a shaft and the cross-brace is mounted so as to be pivotable about the axis of the shaft.

5. The apparatus of claim 4 , wherein the length of the shaft and the position of the arms on the body are such that the arms lie outside the outer ends of a cross-member provided at the end of the handle.

6. The apparatus of claim 4 , wherein the length of the shaft and the position of the arms on the body are such that the arms are positioned laterally beyond the handle.

7. The apparatus of claim 2 , wherein the cross-brace is provided with means for engaging with the handle.

8. The apparatus of claim 7 , wherein the cross-brace comprises a plate-like portion which bears against the handle and side flanges which engage with the outer sides of the handle.

9. The apparatus of claim 8 , wherein the cross-brace includes further flanges which engage with the inner sides of the handle.

10. The apparatus of claim 2 , wherein the cross-brace includes a lower portion which is pivotably mounted, in the use position, to the lower edge of the cross-brace and which extends within the handle to engage with the inner sides of the handle.

11. The apparatus of claim 2 , wherein, in the stored configuration, the cross-brace bears against a rear or front region of the body and closes an opening in the rear or front region of the body.

12. The apparatus of claim 11 , wherein the lower portion of the cross-brace lies between the plate-like portion and the opening in the body.

13. The apparatus of claim 11 , wherein the flanges like within the opening.

14. The apparatus of claim 11 , wherein the flanges extend around the outside of the body.

15. The apparatus of claim 2 , wherein, in the deployed configuration, a rearward facing side of the bracing means is provided with at least one hook for supporting at least one fluid container.

16. The apparatus of claim 15 , wherein the at least one hook is arranged such that the point of support for the at least one container at a sufficiently high level for the contents of the container to flow into the apparatus under the influence of gravity.

17. The apparatus of claim 15 , wherein the at least one hook is arranged such that the point of support for the at least one container is between front and rear axle axes of the apparatus.

18. The apparatus of claim 1 , and including a switch provided on the handle in order to control operation of the apparatus.

19. The apparatus of claim 18 , wherein a cable for the switch is arranged on a reel which is biased to retract the cable.

20. The apparatus of claim 19 , wherein the switch is detachable from handle such that, when detached, the switch is biased to be retracted towards the reel.
