Abstract
Abstract Apparatus for maintaining close proximity between a vehicle surface and a forced air water stripper but without contacting the vehicle surface. A sonar detector is connected into a closed loop control system for maintaining close proximity between a Venturi type forced air outlet nozzle and the vehicle surface. Both horizontal vehicle surfaces and vertical vehicle surfaces may be treated. A novel support arm made of one or more plastic panels is also disclosed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
107 words
Vehicle surface treating apparatus such as a forced air water stripper comprising: a treatment device such as an air nozzle which is to be maintained in proximity to a vehicle surface, support means for said device, power means for controlling the position of said support means thereby to maintain the device in a given proximity to said surface, and non-contacting proximity detector means carried by said support means, aimed at said surface and producing an output representing the distance between said detector and said surface, said output being connected to said control means; and means for maintaining a given aiming orientation between said detector and said surface.
Claim 2
Dependent Claim
107 words
Vehicle surface treating apparatus such as a forced air water stripper comprising: a treatment device such as an air nozzle which is to be maintained in proximity to a vehicle surface, support means for said device, power means for controlling the position of said support means thereby to maintain the device in a given proximity to said surface, and non-contacting proximity detector means carried by said support means, aimed at said surface and producing an output representing the distance between said detector and said surface, said output being connected to said control means; and means for maintaining a given aiming orientation between said detector and said surface.
Claim 3
Dependent Claim
14 words
Apparatus as defined in claim 1 wherein said detector means is a sonar detector/transmitter.
Claim 4
Dependent Claim
21 words
Apparatus as defined in claim 1 wherein said orientation-maintaining means comprises a universal mount connecting said detector to said support means.
Claim 5
Dependent Claim
14 words
Apparatus as defined in claim 1 including bias means operating against said power means.
Claim 6
Dependent Claim
40 words
Apparatus as defined in claim 1 wherein said support means comprises a rigid frame and at least one panel mounted on said frame, said panel having a distal end which is bent back on itself to form a nozzle plenum.
Claim 7
Dependent Claim
51 words
Apparatus as defined in claim 1 wherein said support means comprises a hollow conduit which is substantially rectangular in cross-section and which has a mounting end and a distal end, a nozzle plenum formed at said distal end and in air flow communication with said conduit for receiving air flowing therethrough.
Claim 8
Dependent Claim
72 words
In a water stripper apparatus, a nozzle and nozzle support arm adapted to be pivotally mounted relative to a vehicle in a wash/dry lane and comprising a continuous elongate panel having a mounting end and a distal end, said panel being bent back on itself at said distal end to form a Venturi shaped air plenum having at least one air outlet formed therein, and means for supplying air to said plenum.
Claim 9
Dependent Claim
72 words
In a water stripper apparatus, a nozzle and nozzle support arm adapted to be pivotally mounted relative to a vehicle in a wash/dry lane and comprising a continuous elongate panel having a mounting end and a distal end, said panel being bent back on itself at said distal end to form a Venturi shaped air plenum having at least one air outlet formed therein, and means for supplying air to said plenum.
Claim 10
Dependent Claim
16 words
Apparatus as defined in claim 7 wherein said apparatus further comprises a frame carrying said panel.
Claim 11
Dependent Claim
18 words
Apparatus as defined in claim 7 wherein said panel is integrated into a box section air supply conduit.
