摘要:
A blower system (10) for use in a car wash includes a support plenum (12) comprising two side supports (14, 16) and an overhead support (18), each supporting a blower bag (24, 26, 28). The blower bags (24, 26, 28) are comprised of flexible material. Long and short gussets (46, 48) are spaced across the width of the bags (24, 26, 28) to maintain the bags in a substantially rectangular cross section shape throughout the length of the bag (24, 26, 28). The bags (24, 26, 28) taper to a nozzle (32) to supply the pressurized air to the vehicle.

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).
摘要:
A support having an inverted U-shape defining a top plenum for distributing air and extending along a top plenum axis and a pair of legs extending downwardly from the top plenum in a spaced and parallel relationship. The top plenum of the support defines an attachment opening at an attachment angle. A bag extends downwardly at the attachment angle from the top plenum to a distal end in an inflated position. A nozzle is disposed the distal end of the bag to define a nozzle opening extending along a nozzle plane. The bag includes a major length and a curved portion. The curved portion of the bag includes a minor length and a filler length. The filler length positions the nozzle to be slanted open at a first nozzle acute angle of 20° forwardly in the inflated position and at a second nozzle acute angle of 20° rearwardly in an up position.
摘要:
An assembly for blowing liquids from the surfaces of a vehicle comprising support plenum (10) for distributing a stream of air to the surfaces of a vehicle, a blower (16) connected to said support plenum (10) for producing the stream of air, and an overhead bag (18) extending downwardly from the plenum (10) to a distal end. A nozzle is disposed at the distal end and includes a center section (20) having a length (Y) extending horizontally between ends for directing air against the top of a vehicle. The nozzle is characterized by including an inwardly directed end section (22) at each end of the center section (20) to define outward tips (24) of the nozzle for directing air downwardly and inwardly against the sides of a vehicle. A positioner (30) positions the vehicle to combine with the geometric configuration of the overhead bag (18) to assure that the stream of air emitted from the nozzle tips (24) impacts the sides of the vehicle.
摘要:
A drying apparatus (10) for a vehicle washing system maintains blower air bags (18) a predetermined distance from the vehicle without contacting same providing forced air against the vehicle. Ultrasonic sensors (66) are provided on front and back sides of the nozzle (26) for sensing objects within a predetermined distance in combination with control circuitry. The control circuitry controls a motor (42) to retract a cord (36) to in turn raise or move out of the path of the vehicle, the air bag (18) maintaining the predetermined distance from the vehicle. The signals from each of the sensors (66) are each combined to control the motor. The control circuitry includes and oscillator, counter circuit and integrator for producing a distance ramp, and an echo detector for receiving the reflected signal for comparison to the distance ramp to determine the distance of the sensor (66) from the object.

摘要:
A nozzle assembly (26) to be connected to an outlet 24 of a flexible inflatable bag (18, 20) for emitting a stream of air under pressure therethrough to remove fluid from the surface of a vehicle including an elongated body having a first pair of oppositely disposed walls (28, 30) spaced a predetermined distance apart and a second pair of oppositely disposed walls (32, 34) extending between the first pair of walls (28, 30) and spaced from each other a lesser distance than the spacing of the first pair of walls (28, 30). The body further includes an inlet portion (36) defining a first elongated opening (37) and being adapted to be connected to the bag outlet (24) and a nozzle portion (38) defining a second opening (40) having a smaller area than the first opening (37). The nozzle assembly (26) is characterized by including a plurality of webs (42) extending between the second pair of walls (32, 34) and into the nozzle portion (38) for preventing the second pair of walls (32, 34) and the nozzle portion (38) from being forced apart by the pressure of the stream of air passing therethrough while minimally agitating the stream of air.
摘要:
An apparatus for stripping fluids from the surface of a vehicle (26) including a plurality of dimensionally stable and substantially rigid bags (12) including an inlet (14) for introducing air under pressure into the bag (12) and an elongated opening at one end of the bag (12) defining a nozzle end (16,16') of smaller cross sectional area than the inlet (14) for emitting a stream of air. A support structure including an air distributor (18) supports the bag (12) to extend toward the object (26) wherein the nozzle end (16,16') of the bag (12) lies in the path of motion of the object (26) to cause physical engagement between the nozzle end (16,16') of the bag (12) and the object (26) to bring the stream of air emitted from the nozzle opening into close spacial relationship with the surface of the object (26) to strip fluid from the object. A bellows member (36) operatively connects the bag (12) to the air distributor (18) at one end to provide flexible joints for allowing hinging movement of the bag (12) substantially along a single axis. The bags (12) are self supporting from the air distributor (18).
