[0034] Other areas of application of this disclosure will become apparent from the detailed description, claims, and drawings. The detailed description and specific examples are intended for illustrative purposes only and are not intended to limit the scope of this disclosure. Attached Figure Description
[0035] This disclosure will be more fully understood from the detailed description and accompanying drawings, in which:
[0036] Figure 1 This is a side view of a traction plate according to the principles of this disclosure, which is inserted under the vehicle tire to help the tire regain traction and get out of the stuck situation.
[0037] Figure 2 yes Figure 1 A top view of the traction plate; and
[0038] Figure 3 This is a side view of a towing plate according to a second embodiment of the present disclosure, wherein the towing plate is inserted under the vehicle tire to help the tire regain traction and escape the stuck situation; and
[0039] Figure 4 yes Figure 3 A cross-sectional view of the traction plate shows the pivot support of the fingers mounted to the traction plate.
[0040] In the accompanying drawings, reference numerals may be used repeatedly to identify similar and / or identical elements. Detailed Implementation
[0041] refer to Figure 1 The tow bar assembly 10 is shown inserted under the vehicle tire 12 to help the tire 12 regain traction from a stuck condition. Figure 1 and 2 As shown, the traction plate assembly 10 includes an elongated plate body 14 having a width between 10 and 14 inches, more specifically about 12 inches, and a length between 36 and 60 inches, more specifically about 48 inches.
[0042] End plate 16 is pivotally attached to end 14a of elongated plate body 14. Both elongated plate body 14 and end plate 16 can be made of plastic or metal and can be pivotally connected to each other via pivot pin 18. The elongated plastic or metal body 14 and end plate 16 may include traction grids formed thereon.
[0043] The hinged end plate 16 is designed to prevent the traction plate assembly 10 from being embedded in a soft surface. Specifically, when the elongated plate body 14 of the traction plate assembly 10 begins to slide rearward, the end plate 16 will have rotated to an upward pivot position. Figure 1 The diagram shows a clockwise trend to prevent the end of the elongated plate body 14 from being embedded in the soft surface. The end plate 16 may have a pointed tip for easier insertion under the tire edge.
[0044] refer to Figure 3 and 4 A second embodiment of the tow bar assembly 20 is shown for insertion under the vehicle tire 12 to help the tire 12 regain traction from a stuck condition. The tow bar assembly 20 includes an elongated plate body 22 having a width that can be between 10 and 14 inches, more specifically about 12 inches, and a length that can be between 36 and 60 inches, more specifically about 48 inches.
[0045] One or more fingers 24 are pivotally attached to the elongated plate body 22 to extend beneath it. The elongated plate body 22 includes a rotation stop 26 that restricts the rotation of the fingers 24 about a pivot pin 28. Both the elongated plate body 22 and the fingers 24 may be made of plastic or metal. The fingers 24 are designed to prevent the traction plate assembly 20 from being pushed backward and embedded in a soft surface.
[0046] As the elongated plate body 22 moves rearward, the loose material tends to spread out its fingers, thereby increasing the effective contact area and preventing the plate body 22 from embedding into the surface. The elongated plate body may have a pointed tip for easier insertion under the tire. The torsion spring 30 can bias the fingers downward to improve their contact with the ground. The stop surface 26 can prevent the fingers 24 from spreading beyond a certain point.
[0047] Example embodiments are provided so that this disclosure will be thorough and will fully convey the scope to those skilled in the art. Numerous specific details, such as examples of specific components, apparatuses, and methods, are set forth to provide a thorough understanding of embodiments of this disclosure. It will be apparent to those skilled in the art that the specific details are unnecessary, that the example embodiments may be implemented in many different forms, and that neither should be construed as limiting the scope of this disclosure. In some example embodiments, well-known processes, well-known apparatus structures, and well-known techniques have not been described in detail.
