  • Patent number: 9079594
    Abstract: Because sidewalks are slanted for rain run-off, they pose a safety risk for baby strollers if the person pushing the stroller stops and doesn't apply the brake. If s/he releases the stroller's handle when the brake is not applied, the stroller may veer off towards the curb owing to gravity, wind, the baby's movements, traffic vibrations, etc. Not applying the brake when stopped is a common mistake. While parents may remember to apply the brake when stopped, other caregivers may not. Applicant's improvement provides fully automatic slip-clutch joining means to inhibit veering off by automatically coupling the stroller's rear wheels together when the stroller is stopped. When coupled, the rear wheels must rotate in unison thus helping to prevent the stroller from veering-off toward the curb. When the stroller is being pushed the slip clutch handily becomes disengaged by turning or making other course adjustments.

  • Patent number: 7571033
    Abstract: System for detecting stability/instability of behavior of a motor vehicle upon occurrence of tire slip or lock. State of the motor vehicle is determined on the basis of an alignment torque (Ta) applied from a road and a side slip angle (?). By taking advantage of such torque/slip-angle characteristic that although the alignment torque is proportional to a side slip angle when the latter is small, the alignment torque becomes smaller as the side slip angle increases, a normal value is determined from a straight line slope and the side slip angle in a region where the latter is small. Unstable behavior of the motor vehicle is determined when deviation of actual measured value from the normal value increases. Further, unstable state is determined when the slope of the alignment torque for the slip angle departs significantly from that of approximate straight line slope.

    Abstract: A two-piece apparatus for sliding over a surface. The device includes forward and rear runners connected by a linkage which allows a user to increase deviation of the runners from a horizontal plane at the same time that a deviation from the longitudinal axis of the apparatus occurs. Thus, the user can tilt or edge the runners at the same time that a turn is being implemented. The board provides a narrower waist section than the leading or trailing sections on each of the forward and rear runners. In addition, at maximum articulation of the runners, a substantially smooth arc is formed along the inner edge of the runners so that optimal cornering and shorter radii may be achieved. Preferably, each of the runners includes a set of fins along a rearward edge so that the device may bite into the surface more aggressively.

This first system may be mechanically or hydraulically actuated, but preferably is controlled by a pair of control members whose position relative to the chassis corresponds to the desired position of the wheels relative to the chassis in order to provide an intuitive control mechanism. The second system is the propulsion system which may, for example, take the form of a derailleur drive of the type used in bicycles, but with power from the propulsion system being transmitted to the wheels via a rotating cable and individual gearboxes for each wheel which permit the direction of the wheels to be reversed.

  • Patent number: 5704622
    Abstract: The ice slider has a platform on which a person may stand, sit or lie. Under the platform are two or more ice piece holders which clamp ice pieces such that the ice slider may slide on the ground as for example on sloping terrain. The ice clamps are design to hold the ice piece as the ice melts during use until such time as the use has reduced the ice piece to be unusable for further sliding. In the case where a user is seated, steering brakes may be incorporated to allow steering or stopping the ice slider by friction with the ground.

  • Patent number: 5645296
    Abstract: This invention relates to an air bag inflation gas generator used to inflate air bags such as air bags for impact safety devices, life jackets, rafts, and escape chutes, and aims to simplify its structure extensively as compared with prior art and to make the device compact easily. Combustion gas produced when gas generating agents are burnt passes through a gas filter which is disposed inside the outer wall of a combustion chamber and flows from gas outlets of the outer wall directly into an air bag. When the combustion gas passes through the gas filter, residues contained in the combustion gas is collected by the gas filter to purify the combustion gas. And, the combustion gas produced when gas generating agents are burnt is changed its passage by gas passage changing means, and the residues contained in the combustion gas are collected between a partition member and the gas passage changing means before the combustion gas enters the gas filter.

  • Patent number: 5573257
    Abstract: A coaster having a pair of longitudinally-extending and laterally-spaced flexible sled runners which support and define a path for the coaster along a ground surface. The coaster includes forward, intermediate, and rearward lateral struts extending between the flexible runners. The flexible sled runners extend forward from the forward lateral strut to leading rail ends. A longitudinally-extending body support board is mounted above the runners in such a manner as to-allow it to pivot or tilt, relative to the flexible sled runners, about a longitudinal axis. A steering handle is operably connected to the leading rail ends to laterally displace the leading rail ends and to thereby arc the flexible sled runners. Interlinkage between the steering handle and the body support board pivots the body support board in response to turning the steering handle.

  • Patent number: 5443278
    Abstract: A snowmobile steering ski or skis, which may be equipped with a ski liner to prevent undue drag on a snowmobile snow, includes a integral fin that enhances steering control in turning or resisting sidehill slippage of the snowmobile particularly in traversing powder or hard packed. The ski liner fin is integral, or replaceable, and extends outwardly along the outer edge and downwardly over a central portion of the ski. The fin contacts the snow on the inner side of either a flat turn, or the uphill slope of a sidehill run, because the forward end of the snowmobile ski is cambered so as to tip downwardly toward the steered direction of a turn.

  • Patent number: 5335925
    Abstract: In a ride-on snow sled of the steerable type, a pair of support side runners are fixedly attached to fore and aft vertically oriented legs. The legs are adapted to slide up and down within hollow tubular frame members. The upper ends of the front legs of each runner are attached to one another by a non-compressible and non-extendible cable member. Similarly, the rear pair of legs are connected through a rear tubular frame. Thus, a shift of weight causing the right ski to extend downwardly from the frame causes a proportional lift or rise in the left ski such that the legs on the left ski retract into the frame. With the skis at different heights proportionate to the slope of the hill, an edging effect is created, permitting the operator to traverse the hill without sliding in much the same manner as a skier traverses a hill.
