4. BACKGROUND OF INVENTION

Machine Element or Mechanism/Multiple Levers (74/43)—The inventor came up with the idea to attach a motorized jack to the seat of personal ambulatory scooters after having trouble accessing hard-to-reach areas in his garden. This motorized seat jack mechanism will offer riders vertical mobility in addition to their current distance mobility. John A. Anthony realized a scooter that could better mimic the movements of the human body would be more beneficial to those challenged with limited mobility.

5. BRIEF SUMMARY OF INVENTION

The multiple lever mechanism improves conventional ambulatory scooters by lifting and lowering their seat to give riders vertical maneuverability while in a stationary position. Current personal scooters on the market cause great discomfort to riders attempting to reach areas above or below them.

6. BRIEF DESCRIPTION OF SEVERAL VIEWS OF THE PHOTOGRAPHS

The four photographs allow the examiner to view the multiple lever scooter seat jack in the Extended Position—Caddy Corner where the scissor lift mechanism raises the rider to a higher plane than common scooters at 21 inches

(FIG. 1); a Side View—Lowered Position demonstrating how the mechanism rests just 5½ inches at its lowest point

(FIG. 2); in the Front View—Lowered Position

(FIG. 3) revealing operational components; and in the Rear View—Lowered Position

(FIG. 4) also revealing operational components.

7. DETAILED DESCRIPTION/PREFERRED EMBODIMENT

Manufacturers can install the motorized seat jack in ambulatory scooters to give their product better ability to lift and lower. It rises higher and lowers beneath current scooters. The mechanism is made up of three major components: THE BASE UNIT, THE SCISSOR LIFT and THE SEAT REST. Each part number referenced in the “Detailed Description” below can be found marked on the photos in the “Figures of Proposed Patent” section on pages 10-13. The mechanism is composed of the following parts listed and operates as follows: (see next page)

BASE	1	Tray	14½″ ×	1 - FIG. 1

	2	Micro Switch	N/A	8 - FIG. 1
	2	Motor Mounting	N/A	9 - FIG. 4
		Bracket
	1	Power Cord	12″	10 - FIG. 4

THE BASE UNIT is cradled in a tray (Num1—FIG. 1) that manufacturers can place in ambulatory scooter. A 14″ screw (Num2—FIG. 1) attached to the motor (Num3—FIG. 1), is fined with a handmade nut (Num5—FIG. 1). When the motor rotates the screw in reverse, the momentum pulls in the round bar (Num4—FIG. 3) causing the SCISSOR LIFT to pivot upwards to a maximum of 21″. Slides (Num6—FIG. 1), resting in scissor lift tracks (Num7—FIG. 1) towards the rear of the mechanism stop when they hit a micro switch (Num8—FIG. 1). A second micro switch stops the slides when the SCISSOR LIFT lowers a minimum of 5½″ (see FIG. 2). The motor mounting brackets (Num9—FIG. 4) brace the motor in place. A power cord (Num10—FIG. 4) connects to the power source in most ambulatory scooter.

THE SCISSOR LIFT includes eight pieces of square tubing (Num1—FIG. 1) bolted (Num12—FIG. 2) together in four places. They're placed on either side of the scooter creating two accordion mechanisms. Washers (Num12—FIG. 1) and nuts (Num14—FIG. 1) are used to secure all of the bolts. On top of the unit snap rings (Num15—FIG. 1) hold two round bars (Num16—FIG. 1) in place to cradle the SEAT REST.

THE SEAT REST consist of twin square tubing (Num17—FIG. 3) facing front to back. In the rear (Num17—FIG. 4), they're welded on top of another square tube (Num18—FIG. 4) that's facing side-side. One of the round bars on the SCISSOR LIFT rests inside the squared tubing to allow free rotation as the SCISSOR LIFT rises/lowers. Tubing slides (Num19—FIG. 2) are fitted around each piece of twin square tubing which allows them to move freely as the SCISSOR LIFT rises/lowers. The round bar from the scissor lift runs through the twin square tubing to allow rotation during the lifting and lower of the jack. The placement of the tubing and bars creates a “tic-tac-toe” shape to hold up a scooter seat (see FIG. 1). A steel plate (Num19—FIG. 1) is welded to the center of the “tic-tac-toe” shape and a hollow steel seat stump (Num20—FIG. 3) is welded to the center of the plate to fit into a hole in the bottom of the scooter seat. The stump has three notches to allow the seat to rest in three directions: front, left and right (see FIG. 3).
