Abstract: An aircraft tire chock comprising a triangular-shaped elongated body designed to fit against the surface of a tire on an aircraft. The body includes three longitudinally aligned support members. Disposed between the three support members is a plurality of triangular-shaped gussets, equally spaced apart and vertically aligned inside the body to support the support members. Aligned longitudinally between the support members are three, elongated replaceable bumpers that extend the full length of the elongated body between adjacent support members. Located over each end of the elongated body is an optional end cap. Formed inside each end cap and the end gussets is a centrally aligned bore. Disposed centrally through the bores in the end caps and the gussets is a short, longitudinally aligned pipe. Disposed inside the pipe is a short section of wire rope that is used as a pull handle to move or transport the chock.

Abstract: A method and apparatus for securing a wheeled device such as a shopping cart is disclosed. In one embodiment, the apparatus comprises a body having a bottom surface for engaging a support surface and a top surface defining at least one first stop having a first face and a second face, the first face sloping upwardly from the bottom surface towards the rear face and defining a leading edge positioned near the support surface, an apex provided between the first and second faces, the second face sloping downwardly from the apex, and at least one securing element for securing the cart securing structure to the support surface. In use, the wheels of a cart are rolled over the sloping first face into engagement with the second face. In another embodiment of the invention, the body defines first and second stops having a trough positioned therebetween and the wheels of a cart are rolled over a sloping surface of the first stop into engagement with the trough.

Abstract: A stand-alone centering device is provided for residential and commercial parking spaces to assist a motor vehicle operator in centering the motor vehicle in the space, the device consisting of a resilient floor marker which can be adhesively secured at or near an entrance end of the parking space and positioned such that the motor vehicle operator must align the left or right front tire of the vehicle to roll over the marker followed by the left or right rear tire of the vehicle in order to establish proper alignment of the vehicle in centered relation to the space. An additional marker may be positioned in predetermined relation to the front end of the space to indicate the forward end limit of travel.
