Abstract

A retention mechanism for a hinge mechanism of a door. The retention mechanism comprises: (a) a first portion comprising a keeper and a biasing arrangement configured to bias the keeper toward a locking position, while allowing displacement of the keeper from the locking position to a disengaged position; and a second portion comprising a latch, the latch being configured to displace the keeper from its locking position to its disengaged position and comprising a seat for retaining the keeper therein in its locking position, so as to maintain a door in its open position when the keeper being retained in the seat. The retention mechanism, when operating in conjunction with a hinge mechanism of a door, comprises a clearance area in which, during pivoting of the door between its closed and open positions, there is no contact between the keeper and the latch.

Claims

1. A retention mechanism for a hinge mechanism of a door, the hinge mechanism being configured for articulating a door to the sidewall of a vehicle so as to enable pivoting of the door relative to the sidewall about an axis between a closed position and an open position, the retention mechanism comprising:

a. a first portion comprising a keeper and a biasing arrangement configured to bias the keeper toward a locking position, while allowing displacement of the keeper from the locking position to a disengaged position;

b. a second portion comprising a latch, the latch being configured to displace the keeper from its locking position to its disengaged position and comprising a seat for retaining the keeper therein in its locking position, so as to maintain the door in its open position when the keeper being retained in the seat;

wherein the retention mechanism, when operating in conjunction with the hinge mechanism, comprises a clearance area in which, during pivoting of the door between its closed and open positions, there is no contact between the keeper and the latch.

2. The retention mechanism according to claim 1, wherein when the door is pivoted between its closed and open positions, the latch is configured to pass through the clearance area between a first position in which the keeper and the latch are maximally distant from each other, and a second position in which the latch comes in contact with the keeper, the latch being configured for assuming a plurality of medial positions, in each of which, there is no contact between the latch and the keeper.

3. The retention mechanism according to claim 2, wherein at the second position of the latch, the door is configured to be in an intermediate position between the open position and the closed position of the door, and angled at a first angle with respect to the latter, and wherein at its open position, the door is rotated at a second angle with respect to its closed position, differing from the first angle.

4. The retention mechanism according to claim 3, wherein the first position of the latch is corresponding to the closed position of the door, and the second position of the latch is corresponding to the intermediate position of the door.

5. The retention mechanism according to claim 3, wherein the first angle is about 20 to about 50 degrees.

6. The retention mechanism according to claim 5, wherein the first angle is about 35 degrees.

7. The retention mechanism according to claim 3, wherein the second angle is about 50 to about 80 degrees.

8. The retention mechanism according to claim 7, wherein the second angle is about 70 degrees.

9. The retention mechanism according to claim 3, wherein the clearance area is configured to provide pivoting of the door between its closed position to its intermediate position, while keeping the latch and the keeper at a contact-free configuration.

10. The retention mechanism according to claim 1, wherein the retention mechanism is configured for being attached to an exterior side of a vehicle.

11. The retention mechanism according to claim 1, wherein the first and second portions are isolated from one another in the closed position of the door.

12. The retention mechanism according to claim 1, wherein the biasing arrangement comprises:

a. a biasing plate configured to bear against the keeper; and

b. a spring configured to bias the biasing plate toward the keeper.

13. The retention mechanism according to claim 1, wherein the first portion comprises a housing configured to constrain the keeper to linear motion.

14. The retention mechanism according to claim 1, further comprising a first plate and a second plate articulated to one another by the hinge mechanism, each of the first and second portions being rigidly mounted to the plates, correspondingly.

15. The retention mechanism according to claim 14, wherein the first and second plates are configured to be attached to the door and the sidewall of the vehicle, correspondingly.

20. A vehicle comprising the retention mechanism according to claim 1.

16. A hinge mechanism for a door, the hinge mechanism having a retention mechanism mounted thereon and being configured to enable pivoting of the door relative to a sidewall about an axis between a closed position and an open position, the retention mechanism comprising:

a. a first portion comprising a keeper and a biasing arrangement configured to bias the keeper toward a locking position, while allowing displacement of the keeper from the locking position to a disengaged position;

b. a second portion comprising a latch, the latch being configured to displace the keeper from its locking position to its disengaged position and comprising a seat for retaining the keeper therein in its locking position, so as to maintain the door in its open position when the keeper being retained in the seat;

wherein the retention mechanism, when operating in conjunction with the hinge mechanism, comprises a clearance area in which, during pivoting of the door between its closed and open positions, there is no contact between the keeper and the latch.

17. The hinge mechanism according to claim 16, wherein when the door is pivoted between its closed and open positions, the latch is configured to pass through the clearance area between a first position in which the keeper and the latch are maximally distant from each other, and a second position in which the latch comes in contact with the keeper, the latch being configured for assuming a plurality of medial positions, in each of which, there is no contact between the latch and the keeper.

18. The hinge mechanism according to claim 17, wherein at the second position of the latch, the door is configured to be in an intermediate position between the open position and the closed position of the door, and angled at a first angle with respect to the latter, and wherein at its open position, the door is rotated at a second angle with respect to its closed position, differing from the first angle.

19. The hinge mechanism according to claim 18, wherein the first position of the latch is corresponding to the closed position of the door, and the second position of the latch is corresponding to the intermediate position of the door.
