Abstract

A wiper and washer for a vehicle screen, especially a windscreen, comprises a wiper blade or a pair of spaced wiper blades 3a, 3b, with an elongate inflatable bladder member 4 located adjacent the single blade or between the pair of blades. The inflatable bladder has an outer cover 5 of porous cleaning material and is provided with a series of holes 11. The bladder is normally out of contact with the screen. When cleaning fluid is pumped into the bladder it inflates to contact the screen and the cleaning fluid exits via the holes 11 to clean the screen. The bladder is fed by tubing 8. The bladder is preferably mounted in a flexible 'U' shaped channel 2 to one or both sides of which is mounted the blade[s].

Description

GLASS WIPER.
This invention relates to a Glass Wiper.
Glass Wipers such as vehicle wiper blades are used to clear vehicle windscreens of rain and road trafic film. However the build up of oils and other chemicals within the road film has resulted in normal wiper blades being inadequate even when used in conjunction with chemical glass cleaners.
According to the present invention there is provided a means whereby glass to be cleaned is cleaned by a glass wiper comprising of two known windscreen wipers mounted in parallel between which an inflatable membrane is fitted with a porous cleaning material cover over its outer surface. In normal use the parallel wiper blades work as a dual wiping mechanism with the cleaning material withdrawn and not in contact with the surface to be cleaned. When a known windscreen washer pump is activated suitable pipework supplies the pressurised windscreeen washer cleaning fluid to the inflatable membrane inflating the membrane with the pressurised fluid. The inflated membrane inflates causing the porous cleaning material cover over its outer surface to come into contact with the surface to be cleaned. Suitable fluid outlet or outlets in the outer surface of the inflatable membrane allows the cleaning fluid to soak the porous cleaning material in contact with the surface to be cleaned. The balance between the amount of fluid pressurised by the windscreen washer pump and the amount of fluid exiting the outlets or outlets in the outer surface of the inflatable membrane is chosen to ensure that the membrane inflates the required distance whilst allowing a suitable amount of cleaning fluid to be supplie to the porous cleaning material.
The glass wiper can be operated by the operation of known wiper motors and operating arms or by known manual washer pump and operating arm means.
According to the present invention there is provided a Glass Wiper (1) comprising a flexible'U'channel (2) with known wiper blades (3a, 3b) at both the lengthwise edges (2a, 2b) and in the flexible'U'channel (2) an inflatable membrane (4) fitted with a porous cleaning material cover (5) over its outer surface (4b).
When the inflatable membrane (4) is pressurised by known electrical or mechanical pressure pumps (6) pumping cleaning fluid (7) through suitable pipework (8) the inflatable membrane (4) expands due to the internal pressurised cleaning fluid (7). This moves its porous cleaning material cover (5) outwards from the flexible'U'channels (2) onto the surface to be cleaned (10). A suitable fluid outlet or outlets (11) in the outer surface of the inflatable membrane (4) allows the cleaning fluid (7) to permeate the porous cleaning material cover (5) onto the surface to be cleaned (10).
The Glass Wiper (1) can be operated by the operation of known Motors and operating arms (9) or by known manual means.
A specific embodiment of the invention will now be described by way of examples with reference to the accompanying drawings in which: Figure 1 Shows in perspective the Glass Wiper fitted to a windscreen wiper arm.
Figure2 Illustrates the Glass Cleaner in cross section whereas the inflatable membrane is deflated.
Figure 3 Shows the Glass Cleaner in cross section whereas the inflatable membrane is inflated by pressurised washer fluid.
Figure 4 Shows the Glass Cleaner with the operating arm fitted.

Claims (1)

  1. Claims 1) A glass wiper comprising of two known windscreen wipers blades (3a, 3b) preferably mounted in parallel between which an inflatable membrane (4) is fitted with a porous cleaning material cover (5) over its outer surface (4b). In normal use the preferably parallel wiper blades (3a, 3b) work as a dual wiping mechanism with the cleaning material cover (5) withdrawn and not in contact with the surface with the surface to be cleaned (10). When a known fluid pump (6) is activated suitable pipe-work supplies the pressurised cleaning fluid (7) into the inflatable membrane (4) inflating the inflatable membrane (4) with the pressurised cleaning fluid (7). The inflatable membrane (4) inflates causing the porous cleaning material cover (5) over its outer surface (4b) to come into contact with the surface to be cleaned (10). Suitable fluid outlet or outlets (4a) in the outer surface of the inflatable membrane (4b) allows the cleaning fluid (7) to soak the porous cleaning material cover (5) which is in contact with the surface to be cleaned (10). The balance between the amount of windscreen washer cleaning fluid (7) pressurised by the windscreen washer pump (6) and the amount of cleaning fluid (7) exiting the fluid outlets or outlets (4a) in the outer surface of the inflatable membrane (4b) is chosen to ensure that the inflatable membrane (4) inflates the required distance to allow sufficient contact between the porous cleaning cover (5) and the surface to be cleaned (10) whilst allowing a suitable amount of cleaning fluid (7) to be supplied to the porous cleaning cover (5) 2) A glass wiper (1) as claimed in Claim 1 wherein the inflatable membrane (4) is fitted within a flexible"U"channel (2) with the open section of the flexible"U"channel (2c) facing the surface to be cleaned (10). The flexible "U"channel (2) being fitted between the known wiper blades (3a, 3b) at a suitable distance to allow the porous cleaning material cover (5) to come into contact with the surface to be cleaned (10) when the inflatable membrane (4) is inflated yet be free of the surface to be cleaned (10) when the inflatable membrane (4) is deflated.
    3) A glass wiper (1) as in Claim 2 wherein the flexible"U"channel (2) has the known wiper blades (3a, 3b) fitted along both its lengthwise edges (2a, 2b) 4) A glass wiper (1) wherein the flexible"U"channel (2) has only one known wiper blade (3) fitted along the lengthwise edges (2a or 2b) The inflatable membrane (4) operating in a similar manner as in Claim 1 in that when it is inflated by pressurised cleaning fluid (7) its porous cleaning material cover (5) comes in contact with the surface to be cleaned (10) yet is free of the surface to be cleaned (10) when the inflatable membrane (4) is deflated.
    4) A glass wiper (1) as in Claim 4 wherein the flexible"U"channel (2) is mounted lengthwise to a known vehicle windscreen wiper blade mechanism.
    5) A glass wiper (1) as claimed in any previous claims wherein the glass wiper can be operated by the operation of known wiper motors and operating arms or by known manual washer pumps and operating arm means.
