  • Patent number: 11292392
    Abstract: An automatically extending and retracting step system according to the solution may reside in a retracted state when the deck of a car-carrying vehicle is substantially horizontal to the ground, i.e. when the deck is in a payload state. Advantageously, when the deck is tilted and extended to a ramp state for receiving cargo, the step system according to the solution extends laterally outward from beneath the deck, thereby providing a convenient and visible step for a user to use in getting down from the deck. When the deck is returned from the ramp state to its payload state, the step automatically retracts to a travel state beneath the deck.

  • Patent number: 11293388
    Abstract: The presently disclosed subject matter is generally directed to a system and method of protecting the engines of ATVs by preventing excessive water from entering the belt drive and/or air intake of the vehicle motor. The system includes a riser and valve assembly. Each snorkel valve assembly includes one or more water sensors in communication with a valve. When water is detected by the sensors, the valve closes, preventing water from entering the vehicle engine, transmission, air box, clutch housing, and/or any other vented element of the ATV engine. Instead, the water is diverted out of the system through a drain valve. Accordingly, the system prevents water, mud, and the like from entering the main components of the ATV motor.

  • Patent number: 11254265
    Abstract: A folding staircase. The folding staircase has a frame with an upper end and a lower end. The upper end of the frame defines a top step. Multiple steps are pivotally connected to the lower end of the frame and pivoting arms connects each of the steps to one another. The frame includes brackets that secure to existing mounting points of a vehicle. At least one step is operably connected to a linear actuator, which is in turn connected to a motor. The motor is operably connected to a control switch. Activation and deactivation of the control switch causes the motor to operate resulting in the unfolding of the steps outwardly to a deployed configuration and folding inwardly to a storage configuration. The folding staircase is utilized to provide a safe method of entering and exiting a vehicle.

  • Patent number: 11246427
    Abstract: A child's folding walker with caster wheels that is adjustable in height to permit a child to sit and touch the ground and move the walker. The walker has four vertical legs and two collapsible side frames that enabling the walker to collapse into a vertical configuration. Each collapsing side frame includes a folding upper member and a folding lower member. The proximal ends of the folding members are pivotally attached to a vertical leg. Each upper frame member is made of two elongated sections joined by a locking collar that holds distal ends of the elongated sections together in axial alignment. The locking collar is pivotally attached at its opposite ends to the two elongated sections. When the locking collar is forced upward, the two elongated sections are misaligned thereby enabling the legs to move inward.
