  "title": "Wheel chock",
  "abstract": "An improved wheel chock for use with wheeled vehicles, such as aircraft, that is both adjustable in size and that is configured for relatively easy transport, deployment and maneuverability by a single user is disclosed. The wheel chock preferably comprises a lifting end, a rolling end, at least one segment positioned between the lifting end and the rolling end, and a unique and adjustable wheel assembly. The adjustable wheel assembly may be at least partially housed in a pocket formed in the rolling end of the improved wheel chock. The wheel chock may further comprise a tether and an opening for removably attaching said wheel chock to a second wheel chock to prevent unwanted movement of a vehicle wheel in both forward and reverse directions.",
  "claims": [
    "1. A wheel chock comprising: a lifting end and a rolling end comprising a wheel assembly housing; a mounting bracket removably attachable to the rolling end within the wheel assembly housing; and a wheel assembly attachable to the rolling end via the mounting bracket and retained within the wheel assembly housing; and wherein the wheel assembly comprises a shaft and a pin element in line with and extending perpendicularly outward from the shaft away from the mounting bracket and configured to prevent over rotation of the wheel assembly; and wherein the wheel assembly housing comprises a rear guard extending rearward configured to protect the shaft and prevent over rotation of the wheel assembly in combination with the pin element.",
    "2. The wheel chock of claim 1, wherein the lifting end comprises a handle.",
    "3. The wheel chock of claim 1 further comprising a tether attachable to the lifting end.",
    "4. The wheel chock of claim 1, wherein the wheel assembly is flexible within the wheel assembly housing.",
    "5. The wheel chock of claim 1, wherein the rolling end is curved.",
    "6. The wheel chock of claim 1, wherein the wheel assembly further comprises a shaft offset portion extending perpendicularly outward from the shaft and the pin element, the shaft offset portion comprising a continuous opening parallel to the pin element.",
    "7. The wheel chock of claim 6, wherein the wheel assembly further comprises an adjusting component comprising a threaded fastener movably retained within the continuous opening of the shaft offset portion and threadedly attachable to the to the mounting bracket to hold the adjustable wheel assembly within the wheel assembly housing.",
    "8. The wheel chock of claim 1, wherein the wheel assembly further comprises a pair of spaced apart wheels."

  "description_excerpt": "The present invention relates generally to a chock used to restrict movement of a wheeled vehicle (e.g., an aircraft, tractor trailer, truck, etc.) and, more specifically, to a wheel chock that is easily adjustable in length and that has a flexible wheel assembly and other innovative design features to allow for relatively easy handling and deployment. The improved wheel chock of the present invention is particularly well suited for use with aircraft. Accordingly, the present specification makes specific reference thereto. However, it is to be appreciated that aspects of the present invention are also equally amenable to other like applications and devices.\n\nWheel chocks are necessary safety equipment that are useful for securing parked aircraft to prevent undesired movement of the aircraft, which could result in injury to a person or damage to the aircraft or other property. While the use of wheel chocks to prevent unwanted movement of the wheeled vehicle that they are being used to secure is generally known in the art, such prior art wheel chocks suffer from a number of limitations and performance deviations that are inherently associated with the necessary bulk and weight that the wheel chocks require to safely secure larger wheeled vehicles, such as aircraft, tractor trailers, etc.\n\nMore specifically, existing wheel chocks are typically bulky, heavy, and not ergonomically designed for easy transport and/or deployment. For example, many aircraft related wheel chocks typically weigh between 40-50 pounds or more a piece, and are typically deployed in pairs.",
