Patent ID: 7543395

Claim:
A collapsible device for measuring the height of a road vehicle such as a truck or trailer comprising: an elongate tubular pole having a foot adapted to rest on the ground in use; at least one elongate extension member telescopically and slidably disposed within the pole for selective extension relative thereto and having measurement indicia thereon; a joint mounting member fixedly attached to the distal end of the extension member and defining a pivot axis at right angles to the pole; a contact leg adapted to be placed on top of the vehicle to be measured; a joint having hollow cylindrical portion and a short leg portion integral therewith and extending at a right angle therefrom, the contact leg being fixedly mounted in said cylindrical portion; and a pull-to-release, spring-biased detent mechanism connecting the short joint leg portion to the joint mounting member about said pivot axis for releasably locking the contact leg in each of a stowed position wherein the contact leg is folded into a position which is adjacent to but spaced from and parallel to the extension member, and a deployed position wherein the contact leg is at right angles to the extension member and the short leg portion is at right angles to the pole.
