Abstract

An apparatus (10) for stripping fluids from the surface of a vehicle includes an air distributor (28) and inflatable bags (14-26), each of generally rectangular transverse cross section. The bags (14-26) are supported by the air distributor (28) and each of the bags (14-26) includes an inlet end (40) connected to the air distributor (28) for introducing air under pressure into the bags (14-26) and a nozzle end (42) of smaller area than the inlet end (40) spaced apart from the inlet end (40) for emitting a stream of air while maintaining the bags (14-26) in a nonflailing orientation and substantially rigidly inflated. The invention is characterized by a connector strap (44) having one end portion (46) secured to a first of the bags (14, 18) and a second end portion (48) secured to a second of the bags (16, 20) and spaced along the bags (14-20) from the air distributor (28) for connecting the first bag (14-18) to the second bag (16-20) for properly positioning the second bag (16-20) in relation to a vehicle body when the first bag (14, 18) is deflected by the engaging vehicle (34).

Claims

1. An apparatus (10) for stripping fluids from the surface of a vehicle, said apparatus (10) comprising:

an air distributor (28);

inflatable bags (14,-26), each of generally rectangular transverse cross section, said bags 14-26 supported by said air distributor (28) and each of said bags (14-26) including an inlet end (40) connected to said air distributor (28) for introducing air under pressure into said bags (14-26) and a nozzle end (42) of smaller area than said inlet end (40) spaced apart from said inlet end (40) for emitting a stream of air while maintaining said bags (14-26) in a nonflailing and inflated orientation, and characterized by connector means (44) having one end portion (46) secured to a first of said bags (14,

     18) and a second end portion (48) secured to a second of said bags (16,

     20) disposed above said first bag and spaced along said bags (14-20) from said air distributor (28) for connecting said first bag (14,

     18) to said second bag (16,

     20) for properly positioning said second bag (16,

     20) in relation to a vehicle body when said first bag (14,

     18) is deflected by the engaging vehicle (34).

2. An apparatus as set forth in claim 1 further characterized by said first and second bags (14, 16, 18, 20) being canted with respect to the vertical and horizontal.

3. An apparatus as set forth in claim 2 further characterized by said second bag (6, 20) being canted with respect to said first bag (14, 18).

4. An apparatus as set forth in claim 2 further characterized by said distributor (28) defining a path for a vehicle (34) passing through said apparatus (10), said second bag (16, 20) being supported by said air distributor (28) upstream in the path of the vehicle (34) in relation to said first bag (14, 18).

5. An apparatus as set forth in claim 4 further characterized by said connector means (44) including adjustment means (54) for adjusting the length of said connector means (44).

6. An apparatus as set forth in claim 5 further characterized by said connector means (44) comprising at least one strap having one end (46) secured to said first bag (14, 18) and a second end (48) secured to said second bag (16, 20), said strap including said adjustment means for adjusting the length of said strap.

7. An apparatus as set forth in claim 5 further characterized by said connector means (44) comprising a first strap (50) having one end (46) connected to said first bag (14, 18) and a second strap (52) having one end secured to said second bag (26, 20), said adjustment means adjustably connecting together the free ends of said first and second straps (50, 52).

8. A bag (14, 18) for use as an air distributor for stripping fluids from a passing vehicle (34), said bag (14, 18) being flexible and rigidly inflatable and of generally rectangular cross section, said bag (14, 18) having an inlet end (40) for introducing air under pressure into said bag (14, 18) and a nozzle end (42) spaced apart from said inlet end (40) for emitting a stream of air, and characterized by connector means (44) having one end portion (46) fastened to said bag (14, 18) between said inlet end (40) and said nozzle end (42) and a second end portion (48) adapted to be connected to a second bag (16, 20) for properly positioning one of the bags (16, 20) in relation to the vehicle body when the other bag (14, 18) is deflected by the engaging vehicle (34).

9. An apparatus as set forth in claim 8 further characterized by said connector means (44) including adjustment means (54) for adjusting the length of said connector means (44).

10. An apparatus as set forth in claim 9 further characterized by said connector means (44) comprising a first strap (50) having one end (46) connected to said first bag (14, 18) and a second strap (52) having one end secured to said second bag (26, 20), said adjustment means adjustably connecting together the free ends of said first and second straps (50, 52).

11. An apparatus (10) for stripping fluids from the surface of a vehicle (34) as the vehicle (34) is conveyed along a path through a carwash, said apparatus (10) comprising:

an air distributor (28);

a plurality of flexible inflatable bags (14-26), each of generally rectangular transverse cross section, said bags (14-26) being supported by said air distributor (28) in an array along the path of the vehicle (34) to strip fluid from the side surfaces of the vehicle (34) at least one of a first of said bags (14,

     18) extending substantially laterally from said air distributor (28) and a second of said bags (16,

     20) being disposed above said first bag (14,

     18) and upstream in the path of the vehicle (34), and characterized by connector means (44) having one end portion (46) fastened to said first bag (14,

     18) and a second end portion (48) fastened to said second bag (16,

     20) and spaced along said bags (14-20) from said air distributor (28) for properly positioning said second bag (16,

     20) in relation to the vehicle body when said first bag (14,

     18) is deflected by the engaging vehicle (34).
