Definitions

  • the present invention relates to scooters and scooter like devices and, more specifically, to those that have biased-direction caster wheels and enhance the scooter riding experience.
  • scooter devices that are fun and thereby induce physical exercise while also improving one's balance, physical awareness, and self- confidence. This is particularly important for youth.
  • a rider makes movements similar to those made in skiing.
  • the present invention may serve as a trainer for youth, specifically in skiing and generally in fitness and balance and the like.
  • scooter devices that provide new and different methods of travel and provide new options for athletic training - whether that be for lighter recreational use or more serious athletic competition.
  • Fig. 1 is perspective view of a personal transportation device in accordance with the present invention .
  • Fig. 2 is a front perspective view of the device of Fig. 1.
  • Fig. 3 is a top plan view of the device of Fig. 1.
  • Fig. 4 is a perspective view of the device of Fig. 1 in a stowage position.
  • Fig. 5 illustrates another embodiment of the present invention that has a singular foot support member.
  • FIGs. 1-3 a side perspective, front perspective, and top plan view of a personal transportation device 10 in accordance with the present invention is shown.
  • Figs. 1-3 show device 10 in an in-use position while Fig. 4 illustrates device 10 in a stowage position .
  • Device 10 preferably has two foot support member 20,40 (left and right, respectively, from the perspective of a rider standing on the device) , each having a front direction-biased caster wheel 31,51 and a rear direction- biased caster wheel 32,52, respectively.
  • Foot support members 20,40 are preferably maintained in a substantially parallel arrangement by a linkage assembly 60.
  • Linkage mechanism 60 also preferably permits the foot support members to be moved together or apart and be releasably held at various lateral distances from one another within the range of fully extended (Fig. 1) to fully closed (Fig. 4) .
  • Left and right handle or steering structures 70,80 are preferably provided forward of each foot support member 20,40, respectively. In use, a rider stands facing forward (towards the handles) with a foot on each foot support member 20,40 and a hand on each handle structure 70,80.
  • the left and right foot support members 20, 40 are preferably elongated in the longitudinal or fore-aft axis and have a substantially flat upward-facing surface capable of supporting a human rider's foot.
  • Each foot support members 20,40 may have a foot placement section 22,42 that is substantial flat and configured to receive a foot.
  • the support members have a "saddle" shape with front sections 23,43 and rear sections 24,44 extending above their respective foot placement sections 22,42. This may serve to center a rider' s foot and also provide a raised member or section adjacent thereto to receive the pivot shaft of the caster assembly.
  • the foot support members may be otherwise shaped, including substantially flat in their entirety or other.
  • the level of the foot placement section may be above the caster wheels, between the top of the wheels and their axis of rotation or below the axis of rotation if the wheels are relatively large.
  • the foot support members 20,40 are longer than wide. In the embodiment of Fig. 4, they are nearly 7 or 8 times longer than wide. The ratio may be greater than this, reaching 9 or 10 times or more greater than wide, or less, such as 6, 5 or 4 or less times longer than wide.
  • Fig. 3 also shows that the front sections 23,43 may be slightly wider than other sections of the support member, hence resembling to some extent a downhill ski.
  • a heal cup or tread or other item may be place in foot platform section 22,42 to increase friction and/or secure foot placement.
  • the wheels assemblies are preferably casters capable of swiveling to face any direction but biased to face forward, i.e., direction-biased casters 31,32,51,52.
  • the bias may be achieved by various arrangements, including but not limited to, coupling a biasing spring to each caster wheel or mounting the casters at a forward inclined angle relative to the riding surface. These arrangements are known in the art and permit forward propulsion from side-to-side movement.
  • a rider by shifting his or her weight can push the foot support members sideways and move the casters towards the line of direction of the weight shift (i.e., away from their neutral forward-facing orientation) .
  • the casters return to their neutral orientation and the device travels forward.
  • the device may be propelled forward. Since the two parallel foot support members may resembled skis and quick side to side movement, particularly in a child, may resemble a wiggle, device 10 may affectionately be referred to as "wiggle skis . " Linkage
  • the linkage assembly 60 is preferably coupled to both foot support members 20,40 and holds them parallel to one another while maintaining a predetermined or selected distance between them. While the linkage assembly may be implemented in any of several different arrangements without deviating from the presenting invention, device 10 of Figs. 1-3 illustrates four arms 61-64 with arms 61-62 and 63-64 arranged symmetric about a centerline and arms 61 and 63 moving substantially in parallel with arms 62 and 64.
  • the arms are movably coupled to the support members (preferably to a bottom thereof as shown) and to a releasable arm-locking member 66. Knobs or fasteners 68 may be released and the support members 20,40 set a desired spacing, and then re-fastened or locked. In this manner, the support members 20,40 can be set at any lateral spacing allowed by the length of the arms.
  • device 10 may be moved between the in- use and stowage configurations.
  • the linkage assembly In the in-use configuration, the linkage assembly is locked in an expanded position to maintain distance between the foot support memberss (as shown in Fig. 1-3) .
  • the linkage assembly In the stowage position, the linkage assembly is fully collapsed so that there is no or very little distance between the foot support members, thereby minimizing the overall size.
  • the device may be ridden with the foot support members arranged next to another, as in Fig. 4 (yet with the handles up) .
  • This arrangement would approximate a mono-ski .
  • Handle assemblies 70,80 are preferably assembly is disposed at the front of each foot support member 20,40, respectively.
  • Each handle assembly 70,80 may include an elongated shaft 72,82 which is generally vertically oriented so that a rider's hands grab a handle or grip 71,81, respectively, provided at a top thereof.
  • the handle assemblies, in the in-use position, are preferably rigid to provide support for the rider.
  • the handle assemblies are preferably connected to their respective front casters so that laterally tilting a handle assembly causes a similar tilt in the corresponding front caster (i.e., on the roll axis), resulting in a turning of device 10. This tilt and turning is shown, for example, in Fig. 2.
  • Each shaft 72, 82 may have a basal joint that allows the shaft to be folded rearward and downward toward the foot support members (Fig. 4) to reduce the size of the scooter for stowage or carrying.
  • a locking apparatus may be provided on each shaft .
  • Engaging the locking apparatus locks the shaft in vertical, unfolded position.
  • Disengaging the locking apparatus allows the joint to pivot and the shaft to fold downward.
  • the locking apparatus 75,85 may be a tube member encircling the shaft. The tube member is capable of sliding along the shaft to either cover or expose the joint. When the tube member covers the joint the locking apparatus is engaged and the shaft cannot fold. When the tube member is slid upward to expose the joint the locking apparatus is disengaged and the shaft can be folded.
  • Various releasable locking mechanisms for a pivoting joint are known in the art and may be used herein without deviating from the invention.
  • the rider may be an option for the rider to operate the device while the linkage assembly is partially or wholly unlocked.
  • the foot supports could be moved forward and backward relative to each other during use.
  • the parallel arrangement of the support members would preferably be maintained.
  • the linkage assembly could be configured to allow the foot support members to be moved closer and farther apart during use. These configurations would allow additional or enhanced techniques for propulsion and increase maneuverability and the excitement of riding the device, particularly for skilled riders.
  • the handle assemblies may also be made to be partially or wholly unlockable in the fore-and-aft dimension to enhance the riding and use experience.
  • FIG. 5 a side perspective view of another embodiment of a personal transportation device 110 in accordance with the present invention is shown.
  • Device 110 is similar to device 10 discussed above, yet has a single foot support member 120, handle assembly 170, and front and rear biased caster wheels 131,132.
  • This scooter can be propelled by side-to-side movement and steered by tilting the handle assembly laterally. It can also be operated similarly to a conventional kick scooter.
  • This embodiment may be a separate scooter, or it may be detachable from the two-foot support member device 10 of Figs 1-4.
  • any of the embodiments herein may have a brake mechanism.
  • This may include a cable brake on the handle structure, or a friction brake activated by a rider stepping on the back of the platform or support member or other suitable bra] ing mechanism.
  • Many braking mechanisms are known in the ar
