MOTORIZED WINDSHIELD SCOURER

FIELD OF INVENTION

The present invention relates to the dislodging and removing of vision impairing foreign matter from the windshields of motor vehicles and or motor crafts. In particular, the present invention relates to the dislodging and removing of vision impairing foreign matter that accumulates on the windshields of motor vehicles/crafts that the standard windshield wiper system is incapable of removing.

BACKGROUND OF THE INVENTION

The primary function of the windshield wiper system of a motor vehicle is to remove weather elements such as rain and snow from the windshield, to improve vision for the motorist while driving in inclement weather.

An evolution of the windshield wiper system was the adding of a reservoir of windshield washer fluid and a motorized pump that ejects the washer fluid from the reservoir onto the windshield. Giving the windshield wiper system a windshield cleaning function.

However, in spite of the now standard windshield washer fluid reservoir and motorized pump. That system working together with the windshield wipers, has proven to be incapable of removing splatted on vision impairing foreign matter from the windshields of motor vehicles.

Consequently, to remove insect residue and the like from their windshields, motorists are forced to exit their motor vehicle and use a manual hand-held scourer/squeegee implement that has a coarse/textured mesh wrapped around foam on one side, and a squeegee on the other, attached to a handle.

SUMMARY OF THE INVENTION

In one or more embodiments, the present invention provides the 21st century motorized progression of the hand held manual scouring/squeegeeing tool that is currently being used by motorists to remove splatted on and or stuck on vision impairing foreign matter from the windshields of their motor vehicles.

The present invention, in at least one embodiment, provides a motor-powered windshield scourer for any type of a motor-powered vehicle and or motor craft:

The motorized windshield scourer has motor propelled appendages or a singular appendage that have replaceable scouring attachments joined to the appendages. The motor that propels the appendages can be positioned anywhere on or in the motor vehicle/craft, whether under the hood, in the cabin or elsewhere. The motor driven appendages with joined scouring attachments are mounted and stowed on the windshield of the motor vehicle/craft directly opposite of the windshield wiper blades, or elsewhere. When turned on, the motor moves the appendages with joined attachments in a side to side and or up and down motion across the windshield, or any direction/motion effective for scouring.

The appendages and replaceable scouring attachments can be made of any kind and or combination of materials. However, the material that the appendages are made of will be a type and or combination of unpliable metal(s) such as: Steel, Titanium, Tungsten, or Inconel. And the portion of attachments that scourers the windshield will be any type of material that is rough enough to effectively scour the windshield without leaving it scratched or damaged, such as: nylon scouring pads or a vinyl coated mesh attached to and covering rubber or foam.

The power-driven appendages and joined scouring attachments, in at least one embodiment, are equal (or nearly equal) in length and similar in width, and these dimensions in one or more embodiment are critical. So that a means can be implemented to exert pressure from the appendages to the scouring attachments, forcing the scouring attachments to be pressured/pressed hard against the windshield. Thus, making the attachments motorized scourers; Scour: “to rub hard especially with a rough material for cleansing” (Webster's).

In order to exert and maintain maximum pressure from the appendages to the scouring attachments so that the scoring attachments stay pressed hard against the windshield; the appendages will have a lock down mechanism, in at least one embodiment. Accordingly, when pressure is exerted and increased from the appendages to the attachments, the locked down unpliable appendages will not back off or bend. Thus, sustaining the necessary pressure for the attachments to effectively scour the windshield, as opposed to just wiping any implement across the surface of the windshield.

The motorized scourer will operate autonomously in at least one embodiment, nevertheless one skilled in the art can design it to run in sync with any windshield wiping system and or off the same motor as the windshield wipers.

The motorized windshield scourer has its own or shares a reservoir of windshield washer fluid with that of the windshield wiper system; and either has its own motorized pump or will rely on the windshield wiper system pump to eject the windshield washer fluid onto the windshield.

After the windshield washer fluid has been excreted onto the windshield via a motorized pump, the motorized windshield scourer will be turned on to scour the windshield of splatted on vision impairing foreign matter such as insect residue and the like.

Once the motorized windshield scourer has liberated the stuck-on vision impairing foreign matter from the windshield, the known windshield wipers will be activated to squeegee off the liberated foreign matter and dirty cleaning fluid. Thus, the motorized scourer working in conjunction with the windshield wiper system will be performing the same function as the hand held manual windshield scourer/squeegee currently being used by motorists today.

In at least one embodiment, an apparatus is provided comprising a first windshield scouring device; wherein the first windshield scouring device includes a first appendage; a first scouring attachment; a first means for exerting a varying an amount of pressure on the first scouring attachment when the first scouring attachment is pressing against a windshield; and wherein the first appendage is configured to cause rotation of the first scouring attachment in response to a motor, when the first scouring attachment is pressed against the windshield.

The first means may include one or more threaded fasteners; wherein rotating the one or more threaded fasteners of the first means causes the pressure exerted on the first scouring attachment to be varied.

The apparatus may further include a second windshield scouring device; wherein the second windshield scouring device includes a second appendage; a second scouring attachment; a second means for exerting a varying an amount of pressure on the second scouring attachment when the second scouring attachment is pressing against a windshield; and wherein the second appendage is configured to cause rotation of the second scouring attachment in response to a motor, when the second scouring attachment is pressed against the windshield.

The second means may include one or more threaded fasteners; wherein rotating the one or more threaded fasteners of the second means causes the pressure exerted on the second scouring attachment to be varied;

The apparatus may further include a first locking mechanism which prevents the first appendage from lifting when pressure is applied from the first appendage or from for example screws connected to the first appendage, to the first scouring attachment. The apparatus may further include a second locking mechanism which prevents the second appendage from lifting when pressure is applied from the second appendage or from for example screws connected to the second appendage, to the second scouring attachment.

The second scouring attachment may include a flexible backing, a nylon material attached to the flexible backing of the second scouring attachment; and a foam material covered by the nylon material.

The apparatus may be further comprised of a first windshield wiper device; and wherein the first windshield wiper device and the first scouring device are controlled to operate in sequence to clean substantially the same first half of the windshield. The apparatus may further include a second windshield wiper device; and wherein the second windshield wiper device and the second scouring device are controlled to operate in sequence to clean substantially the same second half of the windshield which is different from the first half.

In at least one embodiment a method is provided which may include applying a varying amount of pressure to a first scouring attachment and/or a second scouring attachment when the first and/or second scouring attachment is pressed against a vehicle windshield; with the apparatus in one of the forms previously described.

The attachment 8c, including sections 9a and 9b, is flexible so that as pressure is applied to along the length thereof it will yield to the pressure applied and conform to the shape of the windshield.

FIG. 9A shows a screw going through part of an appendage or arm 702 into an unthreaded cylinder 705 that is integrated with a scouring attachment 704.

The cylinder 705 has an opening 705a, an inner chamber 705b, and a closed bottom 705c.

The appendage 702 has a threaded opening 702a. A screw or bolt 708 is shown in FIG. 9A. The screw or bolt 708 has a head portion 708a and a threaded body portion 708b. In operation the threaded body portion 708b is screwed into and partially through the opening 702a as shown in FIG. 9A, and then pushed into the unthreaded cylinder opening 705a. By screwing the screw or bolt 708, the bottom 708c of the bolt 708 pushes down on the closed bottom 705c, and thus on the scouring attachment 704 to exert pressure on the scouring attachment 704, which exerts pressure on a windshield providing a scouring feature.

The appendage 702 may not be attached by the bolt 708 to the scouring attachment 704, but rather the appendage 702 and the attachment 704 may be attached to each other by another device, which may be similar or identical to the manner in which a known windshield wiper appendage is attached to a windshield wiper blade.

The pressure mechanism shown in FIG. 9A, including the appendage 702, bolt 708, cylinder 705, and material 706, may be used in the embodiments of FIGS. 1A-6A in accordance with the present invention. The appendage 702 may be used for any of the appendages 8b, 10b, 108b, 110b, 208b, 210b, 308b, 310b, 408b, 410b, 508b, and 510b. The attachment 704 may be used for any of the attachments 8c, 10c, 108c, 110c, 208c, 210c, 308c, 310c, 408c, 410c, 508c, and 510c. The appendages 8b, 10b, 108b, 110b, 208b, 210b, 308b, 310b, 408b, 410b, 508b, and 510b may have bolt or screw 708 inserted through them as shown in FIG. 9A, and the bolt or screw 708 may be used to exert pressure on the attachments 8c, 10c, 108c, 110c, 208c, 210c, 308c, 310c, 408c, 410c, 508c, and 510c, respectively.

9B shows part of a scouring appendage 712 for exerting pressure on a scouring attachment 716 via a spring 714. The spring 714 may not connect the appendage 712 to the attachment 716, rather another mechanism similar or identical to that used in known windshield wipers may be used to connect or attach the appendage 712 to the attachment 716.

When the appendage 712 is lowered onto a windshield and the spring 714 becomes compressed this adds pressure to the attachment 716. In the lowest locked down pressure there is maximum pressure of the scouring attachment 716 on the windshield. The pressure is maintained via the lock down mechanism and the unpliable steel appendage 712 not allowing back off. The attachment 716 includes an opening 716a and a body portion 716b. The attachment 716 may be attached to a material 718 for scouring.

FIG. 10A shows a plurality of screws, each of which may be identical to screw or bolt 708 shown in FIG. 9A, going through the appendage or arm 702 into the scouring attachment 704. None of the screws or bolts 708 and similar screws or bolts in FIG. 10A may attach the appendage to the attachment 704. The slick and or unthreaded cylinders 705 and similar or identical cylinders, have a bottom 705c and identical or similar bottoms, so that when the bottoms 708c and similar bottoms of the screws or bolts 708 are turned and go down it increases pressure on the scouring attachment 704 to the windshield. There is also has a lock washer 709 so that the screws or bolts 708 will not loosen with vibration etc. FIG. 10B shows part of an appendage 712 for exerting pressure onto the scouring attachment 716 via a spring 714 and a plurality of similar or identical springs. The spring 714 and a plurality of similar or identical springs may not connect the appendage 712 to the attachment 716, rather another mechanism similar or identical to that used in known windshield wipers may be used to connect or attach the appendage 712 to the attachment 716.

The scouring attachment 716 may have attached thereto a ring or loop 719 for attaching to a spring 714, and a plurality of similar or identical springs or loops for attaching to a plurality of similar or identical springs or loops.

In FIGS. 10A and 10B a way of attaching 702 to 704 and 712 to 714, independent of screws 708 or springs 714 may be provided, which may be similar to known ways of attaching a member to a wiper blade or arm.

FIG. 11A shows a top and right perspective view of the apparatus of FIG. 10A attached to the locking mechanism 30 which is attached to the pivot member 8a. The locking mechanism 30 may include semicircular plates 32 and 36 fixed to a member 39. The plate 32 may have a plurality openings 34 including opening 34a. The plate 36 may have a plurality of openings 38 which may be aligned with and correspond with the openings 34. The appendage or member 702 can be fixed in position relative to the plates 32 and 36 by inserting the button or protrusion 703 through one of openings 34, such as through opening 34a as shown in FIG. 11A, and simultaneously inserting another button or protrusion on the opposite side of the member 702, through one of the openings 38 which corresponds with and is aligned with the opening 34a. This holds the member 702 to the windshield 20 in FIG. 1A, so that the scouring member 706 presses against the windshield 20 surface, and cannot be lifted up or rotated up in the direction C10 without removing the button 703 from the opening 34a and also removing the corresponding button on the opposite side of member 702 from the appropriate opening of openings 38. The member 39 may have a stop portion underneath the member 702 which prevents upward rotation in the direction C10, off of the windshield 20. When the button or protrusion 703 is pushed and/or removed from the opening 34a and the similar button or protrusion is removed from the appropriate opening of openings 38, then the member can be rotated in the direction C10 off of the windshield 20 or simply removed.

Similarly, or identically, FIG. 11B shows a top and right perspective view of the apparatus 710 of FIG. 10B attached to the locking mechanism 30 which is attached to a pivot member 8a. The appendage or member 712 can be fixed in position relative to the plates 32 and 36 by inserting the button or protrusion 713 through one of openings 34, such as through opening 34a as shown in FIG. 11B, and simultaneously inserting another button or protrusion on the opposite side of the member 712, through one of the openings 38 which corresponds with and is aligned with the opening 34a.

This holds the member 712 to the windshield 20 in FIG. 1A, so that the scouring member 718 or pad presses against the windshield 20 surface, and cannot be lifted up or rotated up in the direction C10, which is perpendicular or substantially perpendicular, to the directions C1 and C9 without removing the button 713 from the opening 34a and also removing the corresponding button on the opposite side of member 712 from the appropriate opening of openings 38. The member 39 may have a stop portion underneath the member 712 which prevents upward rotation in the direction C10, off of the windshield 20. When the button or protrusion 713 is pushed and/or removed from the opening 34a and the similar button or protrusion is removed from the appropriate opening of openings 38, then the member can be rotated in the direction C10 off of the windshield 20 or simply removed.

An optional pin 701 shown in dashed lines in FIG. 11A, may be used to hold member or appendage 702 to attachment 704, even if the screws or bolts 708 are all no longer in their corresponding cylinders 705. The attachment 704 may slide up and down on the pin 701 coming closer to the appendage 702 and then separating farther away from the appendage 702.

Similarly or identically, an optional pin 711 shown in dashed lines in FIG. 11B, may be used to hold member or appendage 712 to attachment 716, even if the springs 714 are all no longer connected to loops 719. The attachment 716 may slide up and down on the pin 711 coming closer to the appendage 712 and then separating farther away from the appendage 712.

The appendages, such as appendage 8b, and replaceable scouring attachments, such as attachment 8c, can be made of any kind and or combination of materials. However, it is critical and preferred in at least one embodiment that the material that the appendages, such as 8b, are made of will be a type and or combination of unpliable metal(s) such as: Steel, Titanium, Tungsten, or Inconel, and the portion of attachments 8c that scourers and comes in contact with the windshield 2 will be any type of material that is rough enough to effectively scour the windshield without leaving it scratched or damaged, such as: nylon scouring pads or a vinyl coated mesh attached to and covering rubber or foam. The rubber and foam would typically not come in contact with the windshield 20.

The power-driven appendages, such as appendage 8b and joined scouring attachments, such as 8c, in at least one embodiment, are equal (or nearly equal) in length and similar in width, and these dimensions in one or more embodiment are critical. This is done so that a means can be implemented to exert pressure from the appendages, such as 8b, to the scouring attachment, 8c, in an substantially uniformly or evenly applied manner, forcing the scouring attachment such as 8c, to be pressured/pressed hard against the windshield 20. Thus, making the attachments motorized scourers.

In order to exert and maintain maximum pressure from the appendage 8b to the scouring attachment 8c so that the scouring attachment 8c stays pressed hard against the windshield 20; the appendage 8b is connected to the lock down mechanism 30, in at least one embodiment. Accordingly, when pressure is exerted and increased from the appendage 8b to the attachments 8c, the locked down unpliable appendage 8b will not back off or bend. Thus, sustaining the necessary pressure for the attachment 8c to effectively scour the windshield 20, as opposed to just wiping any implement across the surface of the windshield 20.

The motorized windshield scourer has its own or shares a reservoir of windshield washer fluid, such as 15 shown in FIG. 1B, with that of the windshield wiper system or devices 12 and 16; and either has its own motorized pump or will rely on the windshield wiper system pump to eject the windshield washer fluid onto the windshield 20.

After the windshield washer fluid has been excreted onto the windshield 20 via a motorized pump, such as known in the art, the motorized windshield scourer or devices 8 and 10, and other devices shown in FIGS. 1A-6A, will be turned on to scour the windshield 20 of splatted on vision impairing foreign matter such as insect residue and the like.

Once the motorized windshield scourer or devices 8 and 10 has liberated the stuck-on vision impairing foreign matter from the windshield, the known windshield wipers or devices 12 and 16 will be activated to squeegee off the liberated foreign matter and dirty cleaning fluid. Thus, the motorized scourer or devices 8 and 10 working in conjunction with the windshield wiper system or known devices 12 and 16 will be performing the same function as the hand held manual windshield scourer/squeegee currently being used by motorists today.

Although the invention has been described by reference to particular illustrative embodiments thereof, many changes and modifications of the invention may become apparent to those skilled in the art without departing from the spirit and scope of the invention. It is therefore intended to include within this patent all such changes and modifications as may reasonably and properly be included within the scope of the present invention's contribution to the art.
