  • Patent number: 10343705
    Abstract: The stroller having wheels with integral skis is a stroller that can be rolled on wheels or pushed on skis. The skis are integral to the stroller can may be deployed by pulling a handle at the bottom rear of the stroller. Pulling the handle causes a first cable to rotate a distribution bar which causes a second cable and a third cable to be pulled. Pulling the second cable causes rotation of the front axle, which pivots the front skis into position below the front wheels. Pulling the third cable causes rotation of the rear axle, which pivots the rear skis into position below the rear wheels. The handle may be placed into a catch to hold the skis in the deployed position. When the handle is released, a torsion spring in each wheel may cause the skis to return to their positions above the wheels.

  • Patent number: 8505929
    Abstract: A device allowing positioning of wheels of a snowmobile when skis leave a snowy path to continue on a road. The device comprises at least two parallel wheels positioned near each ski, a pair of cylinders placed in connection with each wheel, and controlled by a control box by a driver activating pistons to move the wheels from an upward position to a downward ground position. The upward position corresponds to wheels elevated over the ski when the piston is contracted; and the downward position corresponds to wheels in touch with the ground when the piston is extended. Means of clutch move horizontally the wheels to an external position. A spike located on an arm which supports a wheel is positioned to scratch ground ice for creating a mist when a wheel is in a scratching position.

  • Patent number: 8256156
    Abstract: A portable angler cooler apparatus includes two skis removably connected to a bottom-most circumferential edge of two wheels such that the wheels may remain elevated above a ground surface during transportation. A handle is pivotally coupled to a proximal end of the cooler such that the skis are removably connected to the handle after the skis are detached from the wheels. Each of the skis may have a pair of spring-loaded clips mated to opposed longitudinal edges of each wheel respectively so as to be selectively biased between tensioned and equilibrium positions when engaged and disengaged from each of the wheels and the handle respectively. A T-bar locks selected ones of the compartments at a closed position to prohibit premature disengagement from the cooler during transport.

  • Patent number: 7731222
    Abstract: An assembly and method for adapting a baby stroller to better travel over unstable ground, such as sand. A sledge is provided that has a top surface and a bottom surface. The bottom surface is flat with a beveled front end that enables the sledge to be easily pulled over sand or mud. Retention features, such as semi-cylindrical depressions, are formed in the top surface of the sledge. The retention features enable a baby stroller to be placed atop the sledge without rolling off. Once the wheels of the stroller are attached to the sledge, the sledge can be pulled through sand and mud more easily. The sledge may be supported by wide wheels to help the sledge roll over unstable ground. Furthermore, the sledge may be collapsible so that it can be easily stored when not in use.

  • Patent number: 7021636
    Abstract: A typically one-rider non-powered sports/recreational vehicle has a main body that can be easily converted between a wheeled coaster-wagon configuration and a snow-sled configuration with runners. Typically there are four wheels or four runners: two at front, steerable from a handlebar, and two fixed at rear. For braking in the coaster-wagon configuration, a pair of brake shoe pads, attached to the handlebar, press against the front tires to act as brake shoes when the handlebar is twisted radially via a pair of user handgrips. In the snow-sled configuration, a braking panel, attached centrally on the handlebar, moves downwardly to brake by engaging oncoming snow. In normal use as a coaster or sled, when not braking, this braking panel is nested in an unobtrusive location immediately beneath the front of the main body platform, retained there by spring action that also provides braking hold-off in the coaster-wagon configuration.

  • Patent number: 6682082
    Abstract: A wide ski-like apparatus is provided that can be easily and quickly attached to the axle, or axles, of the larger sized icehouses and trailers in common use today. This is accomplished by the use of a ski-like apparatus that is attached to a wheel rim that corresponds in size and lug pattern to existing rims. A second embodiment attaches directly to the wheels of the trailer or icehouse. The use of skis on snow covered or icy surfaces reduces the amount of friction created by movement of the icehouse and thus, makes it easier to move it into position on the lake or river's frozen surface.

  • Patent number: 6236727
    Abstract: Apparatus, method and computer program product are provided for digitally processing an encrypted data stream scrambled, for example, according to content scrambling system (CSS) technology. This digital processing insures against communication of clear data within the computer system from a central processing unit (CPU) to any accessible structure, such as memory or a system bus. Descrambling of the (CSS) scrambled data stream occurs within a module executing on the CPU, which is followed by reencryption of the data prior to transfer from the CPU. By so processing the data, integrity of copyrighted material is maintained, while allowing for software descrambling of the CSS encrypted data stream. Various techniques for establishing the encryption/decryption algorithm pair employed are described. Decryption of the re-encrypted data can occur at a receiving software module and/or a receiving hardware device, such as a decoder.

  • Patent number: 5265892
    Abstract: The flexible cargo container of this cart partially deflects inside-out as the cart truss supporting it changes orientation pivoting on wheels rotatably mounted at the aft lower extremity of downwardly projecting support struts to serve as a chair. Leg supports providing static stability are pivotably mounted to extend forward thereby resisting tipping moments about the wheel axle with payload located intermediate thereto. Rotation of the forward end of the cart upwardly and rearwardly brings the rearward upper connect strut in contact with the support surface exposing the underside of the flexible container inverted to concavity, resulting in a chair of supine positioning. Support struts making up the truss fold about pivotable connections yielding a non-use flat geometry for storage. Snap releasable interconnections dissociate struts from the truss in further disassembly.
