ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a scooter, and more particularly to a scooter having one or more foldable hand grips.
2. Description of the Prior Art
U.S. Pat. No. 4,761,014 to Huang discloses a typical scooter having a hand grip solidly provided on top of the handle tube and may not be folded relative to the handle tube such that the scooters may not be folded to a compact configuration. Some of the scooters comprise a handle tube which may be folded relative to the scooter body. But, the hand grips also may not be folded relative to the handle tube.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional scooter hand grips.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a scooter including one or more hand grips foldable relative to the handle tube to a compact folded configuration.
In accordance with one aspect of the invention, there is provided a handle assembly comprising a handle tube including a first end, a seat secured to the first end of the handle tube and including a channel formed therein, at least one first fastener secured to the seat and engaged through the channel of the seat, at least one hand grip including a first end slidably engaged in the channel of the seat and including at least one slot formed therein for slidably receiving the first fastener, and means for clamping the first end of the hand grip to the seat. It is preferable that the handle assembly includes a pair of hand grips which may be evenly and solidly secured to the seat with the clamping means.
The handle tube includes a bore formed in the first end thereof, the seat includes an extension engaged into the bore of the handle tube. The extension of the seat includes a notch formed therein, and a second fastener engaged through the handle tube and engaged into the notch of the extension of the seat for securing the seat to the handle tube and for preventing the seat from rotating relative to the handle tube.
The hand grip includes at least one orifice formed therein and communicating with the slot thereof, the orifice of the hand grip includes a size greater than that of the slot of the hand grip, the first fastener includes a neck engageable into the orifice of the hand grip for securing the hand grip to the seat. A spring biasing device is further provided for biasing the neck of the first fastener to engage into the orifice of the hand grip. The hand grip may be slided relative to the seat and may be rotated to engage with the handle tube to a compact folded position.
The clamping means includes a quick release device for securing the first end of the hand grip to the seat. The quick release device includes a clamping bar engaged onto the first end of the hand grip, a second fastener engaged through the clamping bar and secured to the seat, and means for forcing the clamping bar to the hand grip. The forcing means includes a lever having a cam pivotally secured to the second fastener, the cam is engaged and forced against the clamping bar when the lever is rotated relative to the second fastener. The clamping bar includes a curved recess formed therein for receiving the first end of the hand grip and for solidly securing said hand grips to the seat.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
