One or more embodiments described herein relate to a tire sun shield, an attachment system for the tire sun shield, and a method of making and using the tire sun shield.
Tire dry rot or sidewall weather is the visible cracking in a tire when rubber compounds in a tire break down. Dry rot in rubber tires is caused by several factors including too much exposure to ultraviolate (UV) rays from sunlight, harsh weather conditions such as rain and snow, underinflation, or allowing the tires to be unused for extended periods of time.
Some vehicles, such as recreational vehicles (RV) are typically driven for brief periods of time during vacations and then parked and stored for long periods of time. Due to the large size of RVs, RVs are typically stored outside due to cost and space limitations and are thus uncovered leaving the tires vulnerable to environmental factors that could lead to dry rot. Typically, the exterior facing sidewalls of the tires have more exposure to the environmental factors and are thus more susceptible to degradation and dry rot. To protect the tires when parked outside, the tires should be covered to prevent harsh weather and ultraviolet rays from degrading tire rubber thereby causing dry rot and decreasing the longevity of the tires.
Several tire covers have been developed to protect a tire from environmental conditions as described above. For example, U.S. Patent Publication No. US2007/0278846A1 to Fleming describes a tire cover that includes an exterior front panel, side panels, and a rear panel that is installed by slipping the tire cover on the tire and the tire cover is secured by placing a flap connected to a bottom portion of the front panel under the tire.
U.S. Pat. No. 10,780,734 to Hunckler describes a tire cover that is held to the sidewall of a tire by bungee cords which are attached to a spring wire frame of the tire shade fabric. This tire cover is installed by stretching the bungee cords over the top of and behind the tire. Attachment of the bungee cords to the tire shade requires numerous parts including a locking collar, a clip, a D-Ring, and fabric strap.
Hunckler also describes, as a currently available design, fender mounted tire shades that include a square or rectangular shaped fabric and are attached to the fender of an RV by using snap connectors. However, the fender mounted tire shades are attached to the exterior of the fender of the RV utilizing snap connectors along the entire top and sides on the periphery of the fabric.
Although these previous types of tire covers offer protection from UV and environmental elements to prevent dry rot, they have several disadvantages in performance and useability. For example, installation of the cover is made by attaching the tire cover to the tire itself which requires the user to reach into the wheel well to secure the tire cover around the back of the tire. This installation method requires a user to touch the tire and wheel well by bending down and reaching into the wheel well which causes an awkward posture of the user and may cause dirt from the tire and wheel well to get on the user. Other installation difficulties include additional installation steps required to ensure the tire cover is properly secured such as placing the flap of Fleming, which is connected to a bottom portion of the front panel, under the tire to ensure the tire cover does not move, or adjusting the bungees of Hunckler at the front and rear of the tire to a 45-degree angle to ensure the bungees are tensioned correctly to hold the tire shade securely. Furthermore, installing the tire cover to the tire itself causes heat and moisture to be trapped between the tire and tire cover, thus leading to the tire to crack and deteriorate.
Furthermore, although the fender mounted tire cover described in Fleming is not attached to the tire itself, fender mounted tire covers require drilling multiple holes into the exterior of the fender to install one portion of each of the snap fasteners to the RV itself, which requires additional labor and time for initial setup. Furthermore, the numerous snap fasteners attached to the exterior of the fender are visible when the cover is not attached, thus decreasing the exterior aesthetics of the RV. Another problem with fender mounted tire covers is that they are difficult and time consuming to install and uninstall due to the process of attaching and detaching numerous snap fasteners along the periphery of the fabric.
In view of the disadvantages of the currently available tire covers, what is needed is a tire cover that is light weight, sturdy, does not take up as much space to store, is easy to install and uninstall, requires less labor and time for initial setup than currently available designs, does not trap heat/moisture when installed, and maintains the aesthetics of the RV when not in use.
As described above, several tire covers have been developed to protect a tire from environmental conditions. However, disadvantages in performance and useability cause an awkward posture of the user and dirt from the tire and wheel well to get on the user, include additional installation steps required to ensure the tire cover is properly secured, require additional labor and time for initial setup, or decrease in the exterior aesthetics of the vehicle.
In light of the foregoing, it is desirable to provide a tire sun shield, an attachment system for the tire sun shield, and a method of making and using the tire sun shield that is light weight, sturdy, does not take up as much space to store, is easy to install and uninstall, requires less labor and time for initial setup than existing designs, does not trap heat/moisture when installed, and maintains the aesthetics of the RV when not in use.
In accordance with one embodiment, a tire cover comprises a flexible fabric sheet having a front side, a rear side, a top, and a bottom, a flexible frame attached to a periphery of the flexible fabric sheet and having a folded state and an open state in which the flexible fabric sheet is tensioned, a top fastener connected to a periphery of the tire cover adjacent to the top of the flexible fabric sheet and configured to attach to a wheel well of a vehicle, the flexible fabric sheet including one hole located adjacent to the periphery of the flexible fabric sheet on one side of the top fastener and including another hole located adjacent to the periphery of the flexible fabric sheet on another side of the top fastener, a resilient fastener having two ends, one of the two ends being threaded through the one hole from the rear side to the front side of the flexible fabric sheet and another of the two ends being threaded through the another hole from the rear side to the front side of the flexible fabric sheet, and two side fasteners, one of the two side fasteners being attached to the one end of the resilient fastener and another of the two side fasteners attached to the another end of the resilient fastener, the two side fasteners being configured to attach to the wheel well of the vehicle.
The tire cover 10 further includes a flexible fabric sheet 12 that covers the flexible frame 11. The flexible fabric sheet 12 is also a circular shape having a diameter that is slightly larger than the diameter of the flexible frame 11 when unfolded in an open state. Thus, the flexible fabric sheet 12 can be attached along the circumference of the flexible frame 11 by folding the outer circumferential edge of the flexible fabric sheet 12 around the flexible frame 11 to form a hem into which the flexible frame 11 is located. The flexible fabric sheet 12 may also be attached to the flexible frame 11 by other methods such as fabric loops located along the circumference of the flexible fabric sheet into which the flexible frame 11 is located. In another embodiment, the flexible frame 11 may be inserted between two flexible fabric sheets 12 such that the flexible frame 11 is positioned adjacent to a seam joining the two flexible fabric sheets 12.
The flexible fabric sheet 12 may include a single layer or alternatively may include multiple layers. The flexible fabric sheet 12 may include materials that block ultraviolet (UV) rays, reflect sunlight, and/or block heat. When the flexible fabric sheet includes two layers, one of the two layers may include one material and another of the two layers may include another material different than the one material. In one embodiment, when the flexible fabric sheet 12 includes two layers, one of the two layers facing the outside includes a material that blocks ultraviolet (UV) rays or reflects light, and another of the two layers facing the inside includes a material that blocks heat.
In one embodiment, as shown in
In one embodiment, the hem of the single flexible fabric sheet 12 includes an opening to expose a portion of the flexible frame 11. In another embodiment, as shown in
Alternatively, the fabric strap 14 may be sewn directly on the flexible fabric sheet 12. The top fastener 13 may be attached to the fabric strap 14. As shown in
As shown in
In a case a magnet is used as the top fastener 13, one magnet may be attached on or placed within the fabric strap 14. In this case, if the wheel well 16 is not metallic or does not have a magnetic field, an object having a magnetic field may be installed on the wheel well 16 so that the magnet is attracted to the object have the magnetic field to attach the tire cover 10 to the wheel well 16. If the wheel well 16 is metallic or does have a magnetic field, it may not be necessary to install another magnet on the wheel well since the one magnet may be attached directly to the wheel well.
In a case a button loop is used as the top fastener 13, the fabric strap 14 may be configured as a loop and a button may be installed on the wheel well 16 so that the button is slipped through the loop to attach the tire cover 10 to the wheel well 16. A similar configuration may be used for a hook-and-loop fastener or any other fasteners having two parts.
Referring again to
The configuration of the top fastener 13 and side fasteners 19 allow for easy installation of the tire cover 10 such that the attachment points to the wheel well 16 are easily accessible to a user. The user does not have to reach into the wheel well 16 and does not have to bend down into awkward positions. Furthermore, the tire cover 10 is securely attached to the wheel well 16 using fewer attachment points than existing designs and does not need any further adjustment after attachment, thus reducing the time and effort to install the tire cover 10.
A description of the installation process of the tire cover 10 is now provided. The tire cover 10 may be stored in a bag 40 (as shown in
In one embodiment, the tire cover 10 includes the fabric strap 14 including one part 15a of the snap fastener attached thereto and the wheel well 16 includes another part 15b of the snap fastener attached thereto. The user may press the one part 15a to the another part 15b to securely attach the two parts 15a, 15b of the snap fastener thereby securing the top portion 10a of the tire cover 10 to the lip 16a of the wheel well 16 as shown in
