Abstract

A powered omni-directional security, patrol and surveillance vehicle that includes a circular frame and two drive wheels capable of independent powered forward and rearward rotation about a horizontal axis. The drive wheels are adapted to allow the vehicle to spin in place about a vertical axis which intersects the horizontal axis midway between the drive wheels and which is generally centered in the circular frame. An observation platform including an operators control station is mounted to the frame on a lift such that it is capable of selective elevation for superior vantage points. A cab preferably encloses the operator'"'"'s station. A plurality of swivel casters disposed on distal ends of telescopic outrigger arms are circumpositioned about the circular frame.

Claims

1. A security, patrol and surveillance vehicle (10) comprising:

a powered omni-directional vehicle (11) defining a vertical axis (16);

a lift (62) coupled to said omni-directional vehicle; and

a platform (36) coupled to said lift, said platform including an operators station (38) with inputs (31R, 31L) arranged and designed for controlling the motion of said omni-directional vehicle

whereby said lift raises and lowers the elevation of said platform with respect to said omni-directional vehicle.

2. The vehicle (10) of claim 1 wherein said omni-directional vehicle comprises:

a frame (14);

a power source (22) carried by said frame;

first and second drive wheels (12R, 12L) rotatively coupled to said frame, each of said drive wheels capable of independent powered forward and rearward rotation about a horizontal axis (18) that intersects said vertical axis (16), said first and second drive wheels designed and arranged to revolve about said vertical axis; and

a plurality of swivel casters (20) mounted to said frame.

3. The vehicle (10) of claim 2 further comprising:

a first control lever (31R) positioned on a first side of said operators station (38) being operatively coupled to a first motor (26R) for controlling the speed and direction of said first drive wheel (12R); and

a second control lever (31L) positioned on a second side of said operators station (38) being operatively coupled to a second motor (26L) for controlling the speed and direction of said second drive wheel (12L).

4. The vehicle of claim 3 wherein:

said vertical axis (16) passes through said operators station (38); and

said platform (36) is characterized generally by the shape of a disk formed about said vertical axis, said operators station bounded by said platform.

5. The vehicle of claim 1 further comprising:

a plurality of outrigger arms (23) having proximal ends coupled to said frame (14), said outrigger arms disposed along a plurality of radials of said vertical axis and circumpositioned symmetrically about the perimeter of said vehicle (10), said plurality of outrigger arms arranged and designed to extend and retract along said plurality of radials, said plurality of swivel casters (20) coupled to distal ends of said outrigger arms;

whereby said plurality of outrigger arms and said plurality of swivel casters cooperate to support said vehicle (10).

6. The vehicle of claim 1 further comprising:

a cab (52) disposed on said platform (36); and

an operators seat (50) disposed on said platform within said cab.

7. The vehicle of claim 6 further comprising:

armor disposed on said cab, wherein said armor is designed and arranged to protect an operator.

9. The vehicle of claim 1 wherein said vehicle (10) further comprises:

a frame (14),

first and second drive wheels (12R, 12L) rotatively coupled to said frame, each of said drive wheels capable of independent powered forward and rearward rotation about a horizontal axis (18) that intersects said vertical axis (16), said first and second drive wheels designed and arranged to revolve about said vertical axis;

a first control level (31R) positioned on a first side of said operators station being operatively coupled to a first motor (26R) for controlling the speed and rotation of said first drive wheel (12R); and

a second control lever (31L) positioned on a second side of said operators station being operatively coupled to a second motor (26L) for controlling the speed and rotation of said second drive wheel (12L).

10. The vehicle of claim 2 further comprising:

a plurality of outrigger arms (23) having proximal ends coupled to said frame, said outrigger arms disposed along a plurality of radials of said vertical axis and circumpositioned symmetrically about the perimeter of said vehicle (10), said plurality of outrigger arms arranged and designed to extend and retract along said plurality of radials; and

a plurality of swivel casters (20) coupled to distal ends of said outrigger arms;

whereby said plurality of outrigger arms and said plurality of swivel casters cooperate to support said vehicle (10).

11. The vehicle of claim 1 wherein:

said lift is a scissor lift.

13. The vehicle of claim 1 further comprising a control station (38) arranged for controlling the motion of said vehicle and disposed on a lift (62) coupled to said frame,

whereby the elevation of said control station with respect to said frame is selectively adjustable.

8. A vehicle (10) comprising:

a security, patrol and surveillance omni-directional vehicle (11) defining a vertical axis (16);

a lift (62) coupled to said omni-directional vehicle; and

an operators station (38) arranged and designed for maneuvering said omni-directional vehicle coupled to said lift so as to be raised and lowered with respect to said omni-directional vehicle by said lift.

12. In an omni-directional vehicle characterized by a generally circular shaped defining a vertical axis (16) and having a frame (14) and first and second drive wheels (12R, 12L) rotatively coupled to said frame, each of said drive wheels capable of independent powered forward and rearward rotation about a horizontal axis (18) that intersects said vertical axis, said first and second drive wheels being designed and arranged to revolve about said vertical axis, the improvement comprising:

a plurality of outrigger arms (23) having proximal ends coupled to said frame, said outrigger arms disposed along a plurality of radials of said vertical axis and circumpositioned symmetrically about the perimeter of said vehicle (10), said plurality of outrigger arms arranged and designed to extend and retract along said plurality of radials; and

a plurality of swivel casters (20) coupled to distal ends of said outrigger arms;

whereby said plurality of outrigger arms and said plurality of swivel casters cooperate to support said vehicle (10).
