Description

-1 DEFINITION FLEXIBLE WHEEL CHOCKS Technical Area The present invention relates to wheel chocks used in cars, trucks, and buses. The invention specifically relates to a flexible wheel chock that can be used without the need for a separate mounting location on the vehicle, offers the possibility of use without the need for a special holder for the chock, enables automatic operation via electronic / mechanical control, and can perform another function when not in use. State of the Art Generally, wheel chocks are a safety measure used in addition to the vehicle's brakes. The chocks are wedge-shaped and are placed against the wheel to prevent the vehicle from rolling away. When not in use, the wheel chocks are secured to the vehicle's chassis / body with a retainer. Due to the size of the wheel chocks, finding a place to secure them on the vehicle can be challenging. The location of the wheel chock fixing varies depending on the different configurations of the vehicle's systems, increasing the variety of holders. In some configurations, since there is no space for the wheel chock on the vehicle chassis / body, the chock is located inside the driver's cab. Some low-volume configurations require complex mounting designs, resulting in high part and assembly costs. This problem is even more pronounced in vehicles with more than two axles, where at least two mounting blocks are required. A key factor influencing the variety of chocks and their holders is the wheel radius. According to current regulations, the chock must be compatible with the wheel radius. -Different wheel radii require different chocks, and therefore different clamps. In vehicles, a non-folding wedge design is commonly used. A foldable design is also available. While it's easier to find space for it on the vehicle, the high manufacturing cost of this foldable design means it's less commonly used and not preferred. Although the American patent application numbered US20120118680A1 offers a solution regarding the attachment of the wedge to the vehicle, it does not solve the problems described above. Explanation of the Purposes of the Invention Based on the current state of the art, the aim of the invention is to develop a flexible wheel chock that overcomes the shortcomings of existing structures. Another objective of the invention is to eliminate the need for a separate mounting point on the vehicle for securing a flexible wheel chock, by using a wheel chock attached to the vehicle. Another advantage of the invention is that it eliminates the need for a special retainer for the wedge. Another aim of the invention is to develop a solution that enables automated operation through electronic / mechanical control. Another purpose of the invention is that when not in use, it can serve another function, for example, as a fender. To achieve these objectives, a flexible wheel chock has been developed that does not require a separate mounting point on the vehicle and can serve another function when not in use. -3 Explaining the Figures Figure 1 shows a drawing of a wheel chock and retainer in a representative application of the known state of the art.

Fixed end Detailed Description of the Invention The invention relates to the flexible wheel chock (10) attached to the vehicle as shown in Figure 2. The flexible wheel chock (10) has a flexible part (5) at its fixed end (6) which is attached to the chassis / body (4) of the vehicle. When the flexible wheel chock (10) is not in use, the flexible part (5) is folded and its free end (7) is attached to the chassis / body (4) of the vehicle. When the use of the flexible wheel chock (10) is needed, the free end (7) is removed from the chassis / body (4) of the vehicle and left near the point of contact of the wheel (2) with the ground. The vehicle is moved in a controlled manner, the free end (7) is squeezed between the wheel (2) and the ground, and the wheel (2) rests against the flexible part (5). Since the rotation of the wheel (2) is prevented by the flexible wheel chock (10), whose fixed end (6) is attached to the chassis / body (4) of the vehicle and whose other free end (7) is under the wheel (2), unwanted movement of the vehicle due to external forces is prevented. When the flexible wheel chock (10) is not in use, it can also be used as a fender, as shown in Figure 2. Some examples of how the flexible wheel chock (10) can be attached to the vehicle are shown in Figures 3 and 4. The free end (7) can be attached in such a way that it does not protrude from the vehicle, as shown in Figure 3. If there is no structure surrounding the wheels (2) on the vehicle, both fixed, as shown in Figure 4, can be attached. -5 end (6) and free end (7) can be connected to another system on the vehicle, e.g. bumper (8). Some options for the flexible part (5) are shown in Figures 5 and 6. Option 1: A flexible part (5) can be formed as a flat (5a) design made of fabric, rubber, composite etc. materials. Option 2: A flexible section (5) can be created in the form of a wire (5b) design made from rope, cord, chain and similar wire structures. If more than one wire (5b) structure is used, these structures can be placed parallel or diagonally to each other. The length of the flexible part (5) can be adjusted according to varying vehicle heights and wheel (2) sizes. Adjustment can be made on both the fixed end (6) and the free end (7) as shown in Figures 7, 8 and 9. A detachable connection (e.g., bolt) can be used to make adjustments on the fixed end (6). Some options for the free end (7) are given in detail view B in Figure 9. The free end (7) can be flat (7a), round (7b) or polygonal (7c). The free end (7) can be lowered manually or automatically. Figures 10 and 11 show the automatic lowering: The free end (7) is attached to the vehicle, and the free end (7) is lowered by the driver using an electronic / mechanical control unit. While the free end (7) is on the ground, the vehicle moves in a controlled manner. The free end (7) stops the vehicle by being squeezed between the wheel (2) and the ground. For manual / automatic lowering, a roller-type mechanism (9) can be used, the closed and open positions of which are shown in Figure 12.
