Definitions

  • This disclosure generally relates to personal mobility vehicles, such as scooters.
  • scooters have become a popular recreational activity as well as useful means of personal transportation.
  • Scooters have become popular among many age groups and there are many different scooter variations and scooter designs.
  • Scooters can have at least two wheels and a steering mechanism.
  • To ride the scooter a user typically stands on a deck of the scooter and holds onto the steering mechanism.
  • To propel the scooter a user may keep one foot on the scooter deck and, with the other foot, push off from the ground to force the scooter forward.
  • Certain scooters have a pivot assembly that allows a fore portion of the scooter to be folded over an aft portion of the scooter. This can allow the scooter to have a reduced overall size. Certain configurations can ease storing and/or carrying the scooter. Some pivot assemblies can be somewhat loose when the scooter is in the unfolded and/or riding configuration, making the scooter rattle and/or wobble during use. These rattling noises and wobbling movements can detract from the appeal of the scooter.
  • Some scooters have a kickstand that allows the scooter to remain upright when not in use.
  • Some kickstands for scooters are mounted on one side of the scooter deck.
  • a user often dismounts the scooter, holds onto a portion (e.g., handgrips) of the scooter, and pushes by foot the kickstand to swing the kickstand away from the side of the deck.
  • the scooter can then be tilted onto the kickstand so that the kickstand holds the scooter in an upright position.
  • a user can hold onto the scooter, kick the kickstand to swing the kickstand up to the side of the deck, and then step onto the scooter deck.
  • kickstands may require the user to operate the kickstand according to the side of the deck on which the kickstand is mounted. Some users may feel more comfortable employing or disengaging the kickstand from the other side (e.g., left or right) of the scooter and/or prefer to be able to choose and/or alternate sides. Some kickstands may require the user to dismount the scooter to engage or disengage the kickstand.
  • Certain scooters have handgrips that enhance the gripping ability or comfort of the user.
  • Some handgrips are substantially cylindrical and are positioned on either side of the handlebar assembly.
  • the handgrip may include on its outer surface multiple indentations that are spaced apart from one another. The indentations can allow a user to lay each finger in a separate indentation when gripping the handgrip.
  • the substantially cylindrical shape of some handgrips can be unpleasant after prolonged gripping. Some users may find cylindrical handgrips to have a dated and/or unfashionable appearance.
  • Various embodiments of personal mobility vehicles such as scooters, are disclosed that address one or more of the aforementioned problems, or other problems.
  • Some embodiments of the present disclosure relate to a pivot assembly that can help to reduce the rattling noises and/or reduce the wobbling movements of the scooter.
  • Some embodiments of the present disclosure relate to a support assembly for a scooter that can allow the kickstand to be accessed from either side of the scooter.
  • Some embodiments of the present disclosure relate to a handgrip for a scooter that enhances the aesthetics and/or ergonomics of the handgrip.
  • a scooter can include a handlebar assembly, a deck, and a pivot assembly.
  • the pivot assembly can couple the handlebar assembly to the deck.
  • the pivot assembly can include a support assembly, a knob, a brace portion, and a shaft.
  • the support assembly can be pivotably coupled to a bracket by a rod.
  • the bracket can include a rail surface.
  • the rail surface can include a first receiving region spaced apart from a second receiving region.
  • the rail surface can include an intermediate portion disposed between the first and second receiving regions.
  • the intermediate portion can be disposed a first distance away from the rod.
  • the first distance can be greater than a distance between the rod and the first or second receiving regions.
  • the knob can be coupled to a pin by a collar.
  • the knob can slide the pin radially away from the rod.
  • the brace portion can extend across a face of the support assembly.
  • the shaft can pass through the collar.
  • a first end of the shaft can be attached to the knob.
  • a second end of the shaft can be opposite the first end.
  • the knob can be configured so that rotation of the knob in a first rotational direction moves the second end into engagement with the brace portion, thereby inhibiting movement of the handlebar assembly relative to the deck.
  • the knob can advance longitudinally toward the support assembly as the knob is rotated in the first rotational direction. In some embodiments, the knob can remain longitudinally fixed relative to the support assembly as the knob is rotated in the first rotational direction.
  • the scooter can include a foot disposed between the second end of the shaft and the brace portion. In some embodiments, one of the foot and the brace portion can include a protrusion. The other of the foot and the brace portion can include a recess. The protrusion can fit inside of the recess and inhibit rotation of the foot relative to a longitudinal axis of the shaft.
  • the bracket can include a first lateral portion and a second lateral portion.
  • the support assembly can be disposed between the first and second lateral portions.
  • the first receiving region can include an anterior first receiving region and a posterior first receiving region.
