Abstract
Abstract An apparatus for facilitating the washing of large vehicles such as tractor and trailer rigs and the like, comprising a rolling stairway having a liquid reservoir thereon and including a vacuum apparatus, if desired. The apparatus may be readily rolled into the desired position in the proximity of the large vehicle and the operator or service person may climb the stairs to the desired elevation in order to more easily reach the upper areas of the vehicle for cleaning thereof. The liquid reservoir may contain a suitable cleansing solution for facilitating the washing operation for the serviceman. The wheels of the washing apparatus may be selectively locked against rotation when the device is in position to preclude accidental rolling thereof when in use.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
240 words
A washing apparatus for large vehicles comprising a substantially rectangular base member including four side frame members rigidly secured together, a first plate member secured between one spaced pair of the side frame members, a support leg secured to each corner of the base member and extending upwardly therefrom, a first pair of substantially horizontally disposed spaced brace members each secured between a pair of the support leg members and spaced above and in substantial alignment with the first mentioned one spaced pair of side frame members, a second plate member secured between the first pair of brace members and parallel to and offset from the first place member, a second pair of substantially horizontally disposed spaced brace members each secured between the said spaced pairs of support legs and in substantial alignment with and spaced above the first pair of brace members, a third plate member secured between the second brace members and parallel with and offset from the first and second plate members whereby said plate members provide steps for the washing apparatus, said support legs extending above the third plate membeR, a pair of angled support members secured between said pairs of leg supports spaced above the third plate to provide arm rests for the apparatus, a wheel secured to each corner of the base member for portably supporting the apparatus, and brake means carried by the apparatus for selective braking of the movement of the wheels.
Claim 2
Dependent Claim
240 words
A washing apparatus for large vehicles comprising a substantially rectangular base member including four side frame members rigidly secured together, a first plate member secured between one spaced pair of the side frame members, a support leg secured to each corner of the base member and extending upwardly therefrom, a first pair of substantially horizontally disposed spaced brace members each secured between a pair of the support leg members and spaced above and in substantial alignment with the first mentioned one spaced pair of side frame members, a second plate member secured between the first pair of brace members and parallel to and offset from the first place member, a second pair of substantially horizontally disposed spaced brace members each secured between the said spaced pairs of support legs and in substantial alignment with and spaced above the first pair of brace members, a third plate member secured between the second brace members and parallel with and offset from the first and second plate members whereby said plate members provide steps for the washing apparatus, said support legs extending above the third plate membeR, a pair of angled support members secured between said pairs of leg supports spaced above the third plate to provide arm rests for the apparatus, a wheel secured to each corner of the base member for portably supporting the apparatus, and brake means carried by the apparatus for selective braking of the movement of the wheels.
