Abstract

An interchangeable door system (IDS) having a central axis and at least two different opening configurations defined by corresponding different locations of the central axis. The system comprises a wall formed with a wall opening having a circumferential rim and a surface pre-formed with at least a first and a second surface-port. The first and second surface-ports are located along the circumferential rim at locations spaced apart from one another along a direction transverse to the central axis. The system further comprises a door having an outer contour corresponding in shape and dimensions to the opening and being adapted for revolving about the central axis, thereby opening and closing the wall opening. The door is pre-formed with at least a first and a second door-port, the door-ports being located along the outer contour at locations corresponding to the locations of the first and second surface-ports. The system also comprises an interchangeable door arrangement (IDA) adapted to provide selective engagement between each door-port and its corresponding surface-port, forming an engaged port-pair whose location defines the location of the central axis, to thereby bring the central axis into a location of the engaged port-pair, so as to allow the door to operate in the different configurations.

Claims

1. An interchangeable door system (IDS) having a central axis and at least two different opening configurations defined by corresponding different locations of said central axis, the system comprising:

a wall formed with a wall opening having a circumferential rim, said wall having a surface pre-formed with at least a first and a second surface-port, the first and second surface-ports being located along said circumferential rim at locations spaced apart from one another along a direction transverse to said central axis;

a door having an outer contour corresponding in shape and dimensions to said opening and being adapted for revolving about said central axis, thereby opening and closing said wall opening, said door being pre-formed with at least a first and a second door-port, the door-ports being located along said outer contour at locations corresponding to the locations of said first and second surface-ports; and

an interchangeable door arrangement (IDA) adapted to provide selective engagement between each door-port and its corresponding surface-port, forming an engaged port-pair whose location defines the location of the central axis, to thereby bring said central axis into a location of the engaged port-pair, so as to allow said door to operate in said different configurations.

2. An IDS according to claim 1, wherein said wall is a part of a vehicle such that the surface-ports are vehicle ports.

3. An IDS according to claim 2, wherein said wall and/or said door are armored, having at least a portion thereof comprising a base to be protected and an armor layer attached to said base and facing the exterior of the vehicle.

4. An IDS according to claim 3, wherein said vehicle comprises front and rear openings, fitted with respective front and rear doors, one or both doors being fitted with said IDA.

5. An IDS according to claim 4, wherein each door is formed with the first and the second door-port, one of which is closer to the vehicle front and the other is closer to the vehicle rear, and each opening is correspondingly formed with a first and a second vehicle-port at locations corresponding to the locations of said first and second door-port.

6. An IDS according to claim 5, wherein any one of the front and rear doors is adapted, by virtue of said IDA, to selectively function as one of a front-hinged door and a rear-hinged door, depending on the position of the IDA, thereby enabling the doors to function in at least any one of the following modes is provided:

i. ‘

first normal mode’

where both doors are front-hinged;

ii. ‘

first mirror mode’

where the front door is front-hinged while the rear door is rear-hinged;

iii. ‘

second normal mode’

where both doors are rear-hinged; and

iv. ‘

second mirror mode’

where the front door is rear-hinged and the rear door is front-hinged.

7. An IDS according to claim 2, wherein said IDA comprises a hinge unit having a first hinge portion and a second hinge portion articulated to one another via a hinge whose axis constitutes said central axis, to allow said door to revolve about said central axis, wherein said hinge unit is adapted for being selectively attached to each one of the first or second door-port and corresponding vehicle-port, to form an engaged port-pair, so as to determine a desired opening configuration of the doors.

8. An IDS according to claim 7, wherein said IDS further comprises a securing mechanism built in within the vehicle, adapted for supporting the vehicle door from disengaging from the wall of the vehicle, when changing its opening configuration, e.g. when dismounting the hinge unit from one vehicle-port/door-port pair and mounting it on another pair.

9. An IDS according to claim 8, wherein said IDA further comprises a locking unit constructed for selectively allowing said vehicle door to assume a first, locked position, in which said vehicle door is prevented from revolving about said axis, and a second, unlocked position in which said vehicle door is free to revolve about said axis.

10. An IDS according to claim 9, wherein said IDS further comprises an actuator for said locking unit adapted for selectively switching the position of the door from the unlocked to the locked position, said actuator being activated by a handle of the vehicle door.

11. An IDS according to claim 10, wherein said hinge unit and said locking unit are mounted on a mutual base constructed, in turn, to be mounted onto said vehicle door.

12. An IDS according to claim 9, wherein the IDA is adapted for being removed from one vehicle door and mounted onto another vehicle door.

13. An IDS according to claim 9, wherein said hinge unit and said locking unit are integrally formed, constituting an assembly adapted for attachment to a single port pair.

14. An IDS according to claim 13, wherein said assembly is in the form of a motorized hinge, wherein revolution of said first hinge portion about said second hinge portion is controlled by a built-in motor of the hinge.

15. An IDS according to claim 14, wherein said motorized hinge is adapted for retaining the position of the door at any stage of opening/closing thereof, whereby a ‘

locked position’

is defined as any position of the door in which the motor of the hinge prevents the door from revolving about the central axis.

16. An IDS according to claim 9, wherein said hinge unit and said locking unit are mounted onto the internal side of the vehicle and the door such that they are protected by the vehicle itself.

17. An IDS according to claim 2, wherein engagement between each vehicle-port and its corresponding door-port is performed on a remote site different from the manufacturing site of the vehicle, to assume a desired configuration.

18. An IDS according to claim 17, wherein said remote site is any one of the following:

i. ‘

a base site’

, which is a site where the vehicles are located before departing to a new location;

ii. ‘

close proximity site’

, which is any site on the way to said new location; and

even

iii. ‘

on site’

, which is any site at said new location.

19. An interchangeable door system (IDS) having two parallel central axes and two different opening configurations corresponding to said two central axes, the system comprising:

i. a wall formed with a wall opening having a circumferential rim, said wall having a surface pre-formed with at least a first and a second surface-port, the first and second surface-ports being located along said circumferential rim at locations opposite one another along a direction perpendicular to said central axes;

ii. a door having an outer contour corresponding in shape and dimensions to said opening and being adapted for revolving about both said central axes, thereby opening and closing said wall opening, said door being pre-formed with at least a first and a second door-port, the door-ports being located along said outer contour at locations corresponding to the locations of said first and second surface-ports; and

iii. an interchangeable door arrangement (IDA) comprising a first hinge arm connecting said first surface-port with said second door-port and a second hinge arm connecting said second surface-port with said first door-port, so as to allow said door to operate in said different configurations.
