COMPLETE SPECIFICATION PETTY PATENT Invention Title: SCOOTER WITH SHOCK ABSORBER Name of Applicant: JONATHON PAUL DARNELL The following statement is a full description of this invention, including the best method of performing it known to me/us: 2 SCOOTER WITH SHOCK ABSORBER FIELD OF THE INVENTION The present invention relates to scooters and more particularly to a scooter with shock absorber.

BACKGROUND OF THE INVENTION Scooters are popular in recent years due to portability collapsible) and inexpensive. One of such scooters is shown in FIG. 1 and substantially consists of a low, narrow footboard B with a wheel at each end, a raised handlebar A for steering, a seat D welded on the top front portion of footboard B, an oblique member C having one end welded to a base tube Al at the lower portion of handlebar A and the other end releasably secured to a pair of opposite holes D1 and a pair of arcuate grooves D2 of the seat D by bolt E and screw F respectively. Thus, the scooter may be collapsed by unfastening and removing screw F from scooter prior to collapsing handlebar A to footboard B about bolt E. The assembly of scooter is simply a reverse procedure of above. However, the previous design suffered from a disadvantage, there is no provision of shock absorber for lessening the force of shocks and jarring. As understood that such scooter may pose difficulty to the rider while in rolling motion, especially when wheels encounter an irregularity crack, pebble) on the ground. Thus improvements exist.

By providing the shock absorber, a lessening of the force of shocks and jarring is effected, resulting in a more comfortable operation to the rider.

The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.

\\melbfiles\home$\Luisa\Keep\Speci\Petty Patent Scooter with Shock Absorber.doc 13/02/01 4 BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a conventional scooter without the provision of shock absorber; FIG. 2 is an exploded view of a scooter with shock absorber according to the invention; FIG. 3 is a perspective view of the assembled scooter shown in FIG. 2; FIG. 4 is a partial side plan view in part section of FIG. 3 scooter; FIG. 4A is a partial bottom plan view in part section of FIG. 3 scooter; FIG. 5 is a partial side plan view in part section of the collapsed scooter shown in FIG. 3; and FIG. 5A is a partial bottom plan view in part section of FIG. 5 scooter.

\\melb_files\homeS\Luisa\Keep\Speci\Petty Patent Scooter with Shock Absorber.doc 13/02/01 5 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to-FIGS. 2 and 3, there is shown a scooter constructed in accordance with the invention. The scooter comprises a low, narrow footboard 2; a raised handlebar 1 including a lower base tube 11 and a fork 12 with a front wheel 13 rotatably mounted therebetween by driving a pin 1A through the ends of fork 12 and the hub of the front wheel 13; a pair of arcuate members 4 having one ends welded to base tube 11, a pair of opposite holes 41 at the other ends, and a pair of opposite holes 42 adjacent base tube 11; a shock absorber 3 springlike member) having a front end 31 secured between the holes 41 by a bolt 3A and a nut 3B combination, a substantially H-shaped connection member 5 including a pair of narrow front ends 51, a pair of holes 52 at the front ends 51 with the holes 42 pivotably secured therebetween by a bolt 5A and a nut 5B combination, a transverse section 53 threadedly secured to the footboard 2, a slot 54 in the transverse section 53, a pair of opposite holes 55 through the sides of slot 54, and a pair of opposite holes 56 at the rear ends; and an activation member 7 including a pair of threaded holes 72 and 74, a pin 71 having a threaded head passed through holes 55 and the rear end 32 of the shock absorber 3 received in slot 54 to be secured in the threaded hole 72, a pin 73 having a threaded head passed through hole 56 to be secured in the threaded hole 74, and a helical spring 7A put on the shank of pin 73.

Referring to FIGS. 4 and 4A, a partial view of the assembled scooter is shown. By providing the shock absorber 3, a lessening of the force of shocks and jarring is effected, resulting in a more comfortable operation to the rider. Referring to FIGS. 5 and 5A, the collapsing of scooter will now be described in detail. First pull the activation member 7 outwardly until pin 17 and the rear end 32 of shock absorber 3 are \\melb_files\home$\Luisa\Keep\Speci\Petty Patent Scooter with Shock Absorber.doc 13/02/01 6 disengaged. Then pivot footboard 2 and the coupled connection member 5 toward handlebar 1 about bolt 5A until stopped. The collapsed scooter is advantageous for storage and transportation.

While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
