## Abstract

An electrically powered self propelled transfer accessible vehicle having a chair which can be vertically positioned by a lifting frame on the vehicle controlled by an operator of the vehicle to permit a disabled person to move from a wheelchair onto the vehicle chair and then repositioned for the disabled person to enter a ride or attraction at an amusement park or to receive physical therapy.

## Claims

### Claim 1

1) A transfer accessible vehicle for a disabled person comprising:
(A) an electrically powered self-propelled vehicle operated by an attendant and having a chassis having first and second sides;
(B) drive wheels, a steering wheel, a control module operable by said attendant, and a fixed frame secured to said chassis;
(C) a lifting frame carried by said fixed frame;
(D) a chair mount secured to said lifting frame;
(E) a chair for use by said disabled person secured to said chair mount, said chair having a folding arm to permit said disabled person to transfer from a wheelchair to said chair; and
(F) force generation means connected between said chassis and said lifting frame for vertically moving said lifting frame to position said chair at wheelchair height and subsequently at a higher or lower height where said disabled person can transfer from said chair to a desired destination.

### Claim 2 (depends on 1)

2) A transfer accessible vehicle as defined in claim 1, wherein said chair mount includes first and second positions for securing said chair, said first position allowing said disabled person to pivot said chair and said second position securing said chair in a non-pivoting position.

### Claim 3 (depends on 2)

3) A transfer accessible vehicle as defined in claim 2, which further includes a leg rest pivotally attached to a front portion of said chair, said leg rest extending outwardly as said chair is moved from said wheelchair height to a lower height.

### Claim 4 (depends on 1)

4) A transfer accessible vehicle as defined in claim 1, wherein said lifting frame is generally U shaped having first and second arms, said fixed frame further includes first and second guide shafts for said first and second arms.

### Claim 5 (depends on 2)

5) A transfer accessible vehicle as defined in claim 2, which in said first position, further includes a circular plate defining a plurality of spaced apart notches extending inwardly from the outer periphery thereof, a locking member extending into one of said notches to prevent pivoting of said chair, and a lever coupled to said locking member and accessible by said disabled person to remove said locking member from said one of said notches to allow said chair to pivot.

### Claim 6 (depends on 1)

6) A transfer accessible vehicle as defined in claim 1 wherein said fixed frame includes a first lifting frame guide secured to the first side of said chassis and a second lifting frame guide secured to the second side of said chassis, first and second guide shafts secured within said first and second lifting frame guides, respectively, said lifting frame being coupled to said first and second guide shafts.

### Claim 7 (depends on 6)

7) A transfer accessible vehicle as defined in claim 6 wherein said lifting frame guides each include an upper and a lower bearing plate, said first guide shaft being secured to said upper and lower bearing plates of said first lifting frame guide and said second guide shaft being secured to said upper and lower bearing plates of said second lifting frame guide.

### Claim 8 (depends on 7)

8) A transfer accessible vehicle as defined in claim 7 which further includes first and second bearings surrounding said first and second guide shafts, respectively, and first and second bearing housings receiving said first and second bearings, said lifting frame being affixed to said first and second bearing housings.

### Claim 9 (depends on 1)

9) A transfer accessible vehicle as defined in claim 1 wherein said chair includes first and second arms pivotally secured thereto and movable upwardly to permit said disabled person to have access to said chair from either side thereof.

### Claim 10 (depends on 3)

10) A transfer accessible vehicle as defined in claim 3 wherein said leg rest further includes a stop member at said pivotally secured position to prevent said leg rest from dropping vertically downward.

### Claim 11 (depends on 1)

11) A transfer accessible vehicle as defined in claim 1 wherein said control module includes individual levers accessible to an operator to maneuver said vehicle either forward or in reverse.

### Claim 12 (depends on 11)

12) A transfer accessible vehicle as defined in claim 11 wherein said control module further includes a switch to activate said means for moving to cause said lifting frame to move either up or down.

### Claim 13 (depends on 1)

13) A transfer accessible vehicle as defined in claim 1 wherein said fixed frame and said lifting frame are inclined from the vertical position to permit said vehicle to be positioned adjacent an attraction which includes an obstacle.

### Claim 14 (depends on 13)

14) A transfer accessible vehicle as defined in claim 13 which further includes an outrigger affixed to said chassis and contacting the surface on which said vehicle rests to prevent said vehicle from tipping due to the weight of the disabled person being off center.

### Claim 15 (depends on 1)

15) A transfer accessible vehicle as defined in claim 1 wherein said lifting frame and said means for moving said lifting frame are positioned at points relative to said chassis approximately midway between said drive wheels and said steering wheel.

### Claim 16 (depends on 15)

16) A transfer accessible vehicle as defined in claim 15 wherein said fixed frame includes a first lifting frame guide secured to the first side of said chassis at a point approximately midway between said drive wheels and said steering wheel and a second lifting frame guide secured to the second side of said chassis at a point approximately midway between said drive wheels and said steering wheel, first and second guide shafts secured within said first and second lifting frame guides, respectively, said lifting frame being coupled to said first and second guide shafts.

### Claim 17 (depends on 16)

17) A transfer accessible vehicle as defined in claim 16 wherein said lifting frame guides each include an upper and a lower bearing plate, said first guide shaft being secured to said upper and lower bearing plates of said first lifting frame guide and said second guide shaft being secured to said upper and lower bearing plates of said second lifting frame guide.

### Claim 18 (depends on 17)

18) A transfer accessible vehicle as defined in claim 17 which further includes first and second bearings surrounding said first and second guide shafts, respectively, and first and second bearing housings, receiving said first and second bearings, said lifting frame being affixed to said first and second bearing housings.
