  • Patent number: 10479432
    Abstract: A tricycle may be operable between a first mode of operation steerable by a tricycle rider, and a second mode of operation steerable by an individual pushing the tricycle. A rider handle, in the first mode, may be configured to be rotationally coupled with the stem in a manner permitting a tricycle rider to exert forces on the rider handle and thereby turn the fork, and the rider handle in the second mode, being configured to be rotationally uncoupled from the stem, preventing forces on the rider handle from turning the fork. At least one rotation restricted may be included for preventing the front wheel from turning to a position where the front wheel axis leads the fork axis, and for maintaining the front wheel axis in a position trailing the fork axis both when the tricycle is propelled by a tricycle rider in the first mode and when the tricycle is pushed from behind in the second mode.

  • Patent number: 8991847
    Abstract: A quick release structure for a bicycle includes a locking rod fixed securely, wherein the locking rod has a polygonal groove formed therein. The driving post of the locking rod includes a polygonal head. As desiring to lock the locking rod on the bicycle frame or to unlock the locking rod from the bicycle frame, the polygonal head of the driving post retains with the polygonal groove of the locking rod so as to rotate the locking rod. When the locking rod is rotated tightly, the polygonal head of the driving post removes from the polygonal groove so that the locking rod cannot be rotated, and the driving post of the locking rod does not drive the locking rod to rotate loosely after vibration, thereby obtaining positioning safety.

    Abstract: An orthopedic mobility scooter for persons with a compromised leg or foot comprising a frame for supporting the weight of an occupant in a sitting position and a leg rest for supporting the compromised leg. The healthy leg is used to propel the scooter with an unobstructed stride. Wheels are located at the front and rear of the frame. Handles attached to a steering column and connected to a front wheel control the direction of travel. A padded seat is positioned near the center of the frame. A horizontal rod extending perpendicular to the frame is used to connect a leg rest and a stabilizing front wheel. The front horizontal rod and rear axle can both be positioned to either side of the frame to accommodate either a left or right compromised leg or foot. The scooter has enough clearance and stability to surmount obstacles such as street curbs.

  • Publication number: 20090174169
    Abstract: A muscle-powered machine has a frame, a drive wheel rotatably mounted on the frame and rotatable in a plane defining a normal straight-ahead travel direction, and a drive pedal engageable with a foot of a user of the machine and having one end pivoted on the frame forward of the user's foot. The pedal is pivotal through an acute angle on the frame between an upper position and a lower position with the pedal extending at an angle of 90° ±10° to a lower leg of the foot on the pedal. A quotient of the maximum vertical travel of the pedal measured perpendicular to the pedal in its lower end position and the sine of the angle is greater than the length of the pedal measured radially of its pivot. A drive connected between the pedal and the drive wheel converts oscillation of the pedal between its end positions into rotation of the wheel.

    Abstract: A transformable baby rider which can be transformed from baby rider to a toy mower in order to help a child to learn walking. As a child reaches 1 year of age, he or she can start to learn walking by the baby rider mode. When the child grows up, the rider mode can be transformed into the toy mower mode. In doing so, the child can hold the handlebar and begin to learn independent walking.

  • Publication number: 20080116656
    Abstract: The invention relates to a device for the optional guiding of at least one self-steering wheel of a trolley. According to the invention, the wheel is of the type that is mounted on a support that pivots around a vertical axis. The device comprises: a push bar which forms a dual-articulated steering member that can be accessed by the user; means for rotating a first clutch part about the vertical axis in response to steering member movements; and means which can be used at will to couple and uncouple the first clutch part in relation to a second clutch part which is solidly connected to the aforementioned support of the wheel, in response to other steering member movements. In addition, a coin-operated locking device for preventing the movement of the trolley is built into a casing which houses a transmission element of the guiding device and which is fixed to the push bar of the trolley.
