  • Patent number: 8511644
    Abstract: Device that uses the force of one or several persons to help a stuck vehicle get free. It comprises a set of chains of blocks (2) to put in front of the wheels and that are connected by straps (3.6) to a system that will pull them under the wheels while pushing the car by reaction. The forces come from a lever system consisting of a main bar with a triangular part fixed underneath and near its front end. When the operator lifts the bar, the displacement of the extremities of the triangular part away from the wheels creates a pull on the straps while the front end of the bar pushes the car. The blocks become the fulcrum of this lever system. Alternately, a winch fixed on the car bumper pulls on the straps via deviation rollers or rings, transmitting the reaction pushing forces to the car rear part.

The flexible cable allows the mat to bend and conform to the ground surface and can be rolled and folded upon itself. In one embodiment, the planks include at least one recess in a top face for interlocking with a plank of a second mat. The mats can be coupled together in an end-to-end relation to obtain a desired length or width or in a stacked relation to obtain a desired thickness of the road bed.

  • Publication number: 20040094634
    Abstract: A vehicle movement stabilizing device is provided which in effectively functioning braking, acceleration and turning movement during travel of the vehicle by activating the frictional force adding means, reliably controls the start and end of the operation of the frictional force adding means and prevents repetition of unnecessary operations. The vehicle movement stabilizing device is provided with frictional force adding means for increasing the frictional force of the wheels to the road surface by scattering particles and a controller. The controller is structured to start the operation of the frictional force adding means when it detects the operation start conditions based on signals from wheel speed sensors, a hydraulic pressure sensor and a step-in force sensor during braking, and to stop its operation if signals indicating disappearance of the state are detected, thereby preventing repetition of unnecessary operations.

    Abstract: A vehicle traction mat for aiding in traction of a vehicle drive tire on ice is provided. The traction mat comprises a sheet of expanded metal of generally rectangular shape and has a plurality of openings formed threrethrough. The sheet is adapted to be wedged between an iced surface and the drive tire along the leading edge of the drive tire and the sheet includes anti-skid projections on opposing surfaces of the sheet to engage the iced surface and the tire. The projections on one surface of the sheet are for penetrating the ice to retain the sheet in a non-sliding relationship with the ice and the projections on the opposite surface are for engagement with the tire providing traction thereto. In addition, a kit is provided having at least two traction mats for use with different degrees of surface conditions.

  • Patent number: 6673417
    Abstract: Anti-slip floor tiles are provided which are textured with a pattern of spikes. The spikes are preferably pyramidal or conical in shape. The height, angle, and base width of the spikes are important to slip resistance coefficients. Preferred spike dimensions range from about 0.2 to about 3.0 mm in height and from about 0.8 to about 3.0 mm in base width (or diameter). Further, a process for manufacturing an anti-slip floor tile which is textured with a pattern of spikes is provided. The tile is manufactured by pressing a powder on a mold, drying the resulting tile, and then firing the pressed tile at a high temperature. The surface texture is formed by the punch of the mold press which includes spike shaped indentations being the negative of the surface of the tile.

  • Patent number: 6630042
    Abstract: The present invention includes a method of reducing slippage between a mat having a flexible polymer back surface and a substrate surface contiguous to the back surface, the method comprising applying a liquid comprising an aqueous solution of poly(vinyl acetate) to the back surface and contacting the back surface with the liquid thereon to the substrate surface while the aqueous solution is still wet. The method is especially effective where the mat comprises a flexible polymeric back surface comprising a flexible polymer selected from the group consisting of natural rubber, synthetic rubber, natural elastomers and synthetic elastomers. The contacting may be performed before the aqueous solution is completely dried. The aqueous solution may be applied directly to the back surface by spraying said aqueous solution onto said surface. The aqueous solution may be applied directly to the substrate surface.

  • Patent number: 6592288
    Abstract: A high traction anti-icing road cover system; the system includes a pair of base magnetic covers, for example steel plates or flexible non-porous magnetic layers, disposed in grooves in a road surface, such as a bridge span or deck, along the expected tire tracks followed by vehicles. A road cover is constructed of a lamination of a flexible non-porous magnetic layer, an intermediate thermal insulating layer and a tube layer including a plurality of bonded parallel tubes. The plurality of tubes extend obliquely across the width of each road cover. Most of the tubes contain a substance that collapses upon the temperature falling below about freezing; other tubes remain extended above the collapsed surface, to provide better traction in the event of icing of the road surface. All of the tubes are somewhat deformable by the weight of passing vehicles, which mechanically breaks forming ice. Selected tubes may contain a heating coil, coupled to a switch that controllably applies current thereto.
