The present invention relates generally to windshield blades of vehicles. More particularly, the present invention relates to lifter for windshield blades for vehicles.
Many vehicles are provided with windshield wipers to keep the window free from rainfall, insects, bird droppings, or other obstructing things that may fall against the windshield of a vehicle and obstruct the view. In an illustrative example depicting two windshield wipers shown in
For the windshield wiper blade to sweep aside as much of these obstructing things as possible, it is important for there to be good surface contact between the blade and the windshield. Anywhere there is no surface contact or the surface contact is not good, the blade will not sweep aside any or sufficiently remove obstructing things lying on the window.
Extreme weather may affect the surface contact between a blade and a windshield. Extreme cold, such as may occur during cold winter, may cause the rubber of the wiper blade to stiffen due to the cold and cause the blade to crack or deform. Extreme heat, such as may occur during a hot summer, may cause the rubber to tear, warp, or otherwise deform.
To prevent blade cracking or deformation, when snow or freezing conditions are expected, some individuals may lift their wiper blades into a fully extended position away from the window. As depicted in
There exist a number of devices for lifting the windshield blades to a position that lies between the window and the fully extended position of the arm so as to avoid the foregoing illustrative problems with convention windshield wipers. These devices are intricately designed with features to account for the physics at play between the device and the arm and windshield when the device is employed. For example, U.S. Pat. No. 9,381,891 to Petrovic teaches a wiper arm stand having a body 130 and three legs 140 (although it could have two or more legs) and a support 170 for holding the wiper arm away from the window.
U.S. Pat. No. D714,709 S to Bussard. et al. teaches a windshield wiper standoff for placement between a window and a wiper arm designed with certain structural features and a slot at the top configured to hold the wiper arm away from the window.
U.S. Pat. No. 5,873,141 A to Tackett teaches a device placed between a window arm and a window to keep the windshield wiper away from the window. Projections 18 and 66 are features that cause the device to tip over when the wiper arm is turned on and moves against the projection.
U.S. Pat. No. 5,675,861 A to Ayers teaches a device that is placed on a windshield to receive and hold a windshield blade suspended above the windshield. The device has a base with a channel 22 that receives a rotor 20 with a v-shaped channel. The windshield blade moves up the platform and into the v-shaped shaped channel to rotate the rotor to a final position whereby the windshield blade is suspended above the surface of the window thereby extending the life of the blade.

As previously described, many vehicles are provided with windshield wipers to keep the window free from rainfall, insects, bird droppings, or other obstructing things that may fall against the windshield of a vehicle and obstruct the view. In an illustrative example depicting two windshield wipers shown in
This disclosure addresses a need for an improved lifter for wiper blades including for extending the life of wiper blades. Broadly speaking, a lifter for windshield wiper blade of this disclosure includes a body having first and second opposite end portions. The body is horizontally elongate with a vertically low profile. The first and second end opposite portions are without any corners. The first opposite end portion releasably contacts the windshield when the body portion is positioned between a wiper arm and a windshield. The second opposite end portion releasably supports the wiper arm in a spaced apart relationship to the windshield when the first opposite end portion contacts the windshield and the body portion is positioned between the wiper arm and the windshield. The first and second end opposite portions are free from attachment to the wiper arm and the windshield, The body is supportively firm along the vertically low profile and vertically flexible along the second opposite end portion in supporting the wiper arm. The body has a positive water buoyancy.
The lifter of this disclosure extends the life of wiper blades with a low profile and simple, easy to use, user friendly, cost effective, mechano-dynamically modeled, and economically friendly lifter for windshield wiper blade. The disclosed lifter is aesthetically pleasing and enhances surface area for designer graphics and/or personalization. The lifter of this disclosure is biodegradable, ecologically friendly, easily transportable, and with a buoyancy of under 1 floats on water.
The vehicle with which the lifter of this disclosure may be used may be any vehicle including vehicles selected from the group consisting of motor vehicles, including cars, trucks, buses, motorcycles including mopeds and scooters, railed vehicles, including trains and trams, watercraft including ships and boats, amphibious vehicles including screw-propelled vehicle, hovercraft, aircraft including airplanes and helicopters, spacecraft, and wagons, bicycles, and carts including manual push or pull carts and mobile carts, including animal drawn carts and golf carts.
Turning now to the figures illustrating the lifter of this disclosure,
As illustrated in
In one illustrative embodiment, the horizontal elongateness of the body measures about 4 inches in a lengthwise direction of the horizontal elongateness and about 3 inches in a widthwise direction of the horizontal elongateness, and the vertically low profile of the body measures about three inches.
The body 220 is illustratively made from biodegradable materials. By “biodegradable” is meant capable of being broken down (decomposed) rapidly by the action of microorganisms. Biodegradable materials for use with this disclosure may include biodegradable sponge, cotton, wool, wood, manufactured products based on natural materials (such as paper, and vegetable-oil based soaps), cork, bamboo, bioplastics, fibreboard that uses potato starch, and so on.
Preferably the body 220 is made from a biodegradeable foam. Alternatively, body 220 may be made from a biodegradeable hemp plastic. The selection of biodegradable material for use for the body 220 is a matter of design choice.
In an alternatively embodiment, the body 220 may be made from a material that is not biodegradeable. For instance, foamed plastic, rubber, nylon, and any other material that meets the design requirements of this disclosure but that are considered not biodegradeable may be used.
Illustratively, the first and second end opposite portions are without any corners. The absence of corners on the body 220 enhances safety in the use of the lifter, for example, since it removes all corners which may be poked into the eye or used in other ways which may not be safe to the user.
The body 220 may be supportively firm along the vertically low profile. The supportive firmness configures the body 220 to support the weight of the wiper arm in a spaced apart relationship to the windshield when the first opposite end portion contacts the windshield and the body portion is positioned between the wiper arm and the windshield.
The body 220 may be vertically flexible along at least a portion of the second opposite end portion. Alternatively, the body 220 may be vertically flexible along a substantial portion or all of the second opposite end. The vertical flexibility configures the body 220 to cushion the support of the wiper arm when the first opposite end portion contacts the windshield and the body portion is positioned between the wiper arm and the windshield. The vertical flexibility provides soft cushioning for the wiper arm supported thereon while keeping the windshield wiper blade away from the windshield. The amount of vertical flexibility to keep the windshield wiper blade away from the windshield is a matter of design choice.
In use, the first opposite end portion 224 releasably contacts a windshield when the body portion 220 is positioned between a wiper arm and a windshield. The second opposite end portion 222 releasably supports the wiper arm in a spaced apart relationship to the windshield when the first opposite end portion contacts the windshield and the body portion is positioned between the wiper arm and the windshield.
In the foregoing embodiment, the first and second end opposite portions 222, 224, respectively, are free from attachment to the wiper arm and windshield. This allows the body 220 to be easily inserted between the wiper arm and windshield for use and easily removed from between the wiper arm and windshield when not in use.
In the foregoing embodiment, the body 220 may be placed between a wiper arm and windshield when a vehicle is not being used. The body 220 of the lifter 200 advantageously lifts the wiper arm away from the window thereby lifting the wiper blades away from the window so as protect the wiper blades from cracking, stretching, warping, or developing other defects.
In another embodiment, the body 220 is configured to have a positive water buoyance. By “buoyancy” is meant the ability of the lifter of this disclosure to float on water. An object that floats in water is said to be positively buoyant. An object that sinks is negatively buoyant. To determine an object's buoyancy, both its mass and volume must be taken into consideration. The relationship between object's volume and mass is called its density. Density is defined as the mass of an object per unit volume. Mathematically, this relationship is described using the following equation density=mass/volume. An object will float or sink depends on its own density and the density of the liquid it is placed in. In the case of water, an object with a density less than 1 g/cm3 will float. In accordance with this disclosure, the lifter of this disclosure is configured to have a density less than 1 g/cm3.
In another illustrative embodiment depicted in
The lanyard may be any rope or cord and may be made from Nylon, Cotton, Polyester, twill, nylon, polyester, and so on. The attachment mechanism may be an alligator clip with jaws that grab and hold the clip to the part of the lanyard after wrapping of the lanyard around the wiper arm as shown in
In another illustrative embodiment depicted in
The lanyards may be rope or cord made from the materials previously described. The attachment mechanism may be an alligator clip or any of the other attachment mechanisms previously explained. The sliding mechanism 522 may be a ring made from plastic or other material to which is coupled a loop 523 located at one end of the lanyard 520. Alternatively, the lanyard 510 may be threaded through the loop 523 located at the one end of the lanyard 520 to serve as the sliding mechanism; obviating the need for the separate ring.
While illustrative examples of lifter dimensions have been disclosed, it will be appreciated that the dimensions are a matter of design choice subject to the restrictions imposed by this disclosure. For example, the vertical low profile of this disclosure is restricted to less than about three inches in height as previously explained. The length of the lifter is a matter of design choice limited by the arm of the blade between the point of attachment and the windshield blade under which the lifters are placed. The width of the lifter is a matter of design choice limited by the body of the vehicle.
Any number of lifters may be used with a windshield blade, limited only by length of the arm of the blade between the point of attachment and the windshield blade under which the lifters are placed. For example, two lifters may be spaced apart from each other under the wiper arm. The vertically flexibility of the body may allow the lifter closest to the blade to be more flexed than the other lifter. Such an arrangement may help distribute the weight of the wiper arm across two or more lifters. The number of lifters is limited only by the length of the arm of the blade between the attachment point and the windshield arm.
