Abstract

A door is on the body of a vehicle. A handle is on the door to allow movement of the door. At least one rail is on the body to allow the door to slide thereon. A plurality of lock elements are located on the door in connection with the handle which are triggered by the handle to move in the direction they extend. A plurality of slots in the form of a groove are located on the body for allowing the lock element to be inserted and removed therein. The door has a free position in which the door is allowed to move on the rail when the lock element is completely removed from the slot and a locked position in which the movement of the door is restricted when the lock element, which has been at least partially inserted into the slot, contacts the wall of the slot.

First claim

I claim:

1 . A door lock mechanism ( 1 ) comprising:
at least one body (G) on an air and/or space vehicle; at least one door ( 2 ) on the body (G); at least one handle ( 3 ) on the door ( 2 ), which allows the door ( 2 ) to move; at least one rail ( 4 ) on the body (G), which allows the door ( 2 ) to slide thereon; a plurality of lock elements ( 5 ) which are located on the door ( 2 ) in connection with the handle ( 3 ), and are triggered by the handle ( 3 ) to move in a direction they extend; a plurality of slots ( 6 ) in a form of a groove, which are located on the body (G) for allowing the lock element ( 5 ) to be inserted and removed therein; wherein the door ( 2 ) has a free position (F) in which the door is allowed to move on the rail ( 4 ) when the lock element ( 5 ) is completely removed from the slot ( 6 ), and wherein the door ( 2 ) has a locked position (L) in which movement of the door is restricted when the lock element ( 5 ), which has been at least partially inserted into the slot ( 6 ), contacts a wall of the slot ( 6 ); at least one transfer element ( 7 ) located on the door ( 2 ) rotatable around an axis to which it is attached, wherein the transfer element ( 7 ) is triggered by the handle ( 3 ) to activate the lock elements ( 5 ) simultaneously; a sliding element ( 8 ) located in connection with the transfer element ( 7 ) and the lock element ( 5 ), wherein the sliding element ( 8 ) is triggered by rotational movement of the transfer element ( 7 ) to perform a sliding movement on the transfer element ( 7 ), thus enabling the lock elements ( 5 ) to be inserted or removed from the slot ( 6 ) by performing a linear movement due to the rotational movement of the transfer element ( 7 ); wherein the rail ( 4 ) extends longitudinally between the door ( 2 ) and the body (G) and enables the door ( 2 ) to be connected to the body (G); and wherein the slot ( 6 ) is formed within the rail ( 4 ) with an inclined surface ( 13 ) on each side thereof, each inclined surface ( 13 ) configured to allow the lock element ( 5 ) contacting the slot ( 6 ) to slide thereon so as to be inserted into the slot ( 6 ).

2 . The door lock mechanism ( 1 ) according to claim 1 , comprising:
a fastener ( 9 ) enabling the transfer element ( 7 ) to be attached to the body (G) with a freedom of rotational movement; a plurality of plates ( 10 ) which are located opposite to each other on the sliding element ( 8 ) with a distance therebetween, and which at least partially surround the transfer element ( 7 ) on both sides; and a pin ( 11 ) located in the transfer element ( 7 ) in contact with the transfer element ( 7 ) and enabling the plates ( 10 ) to be connected to each other.

3 . The door lock mechanism ( 1 ) according to claim 2 , comprising:
a frame ( 12 ) on the transfer element ( 7 ), which allows the sliding element ( 8 ) to perform a sliding movement therein; and wherein the pin ( 11 ) on the sliding element ( 8 ) performs a sliding movement on a wall of the frame ( 12 ) to trigger the lock elements ( 5 ), thus allowing the door to move between the locked position (L) and the free position (F).

4 . The door lock mechanism ( 1 ) according to claim 2 , wherein the pin ( 11 ), when it contacts the fastener ( 9 ), restricts the rotational movement of the transfer element ( 7 ) at a predetermined angle value, thereby restricting the linear movement of the lock elements.

5 . The door lock mechanism ( 1 ) according to claim 1 , comprising:
a first lock element ( 501 ) and a second lock element ( 502 ) that are located on the sliding element ( 8 ); wherein the lock elements ( 5 ) move in conjunction with the movement of the door ( 2 ) on the rail ( 4 ) when the door ( 2 ) is in the free position (F); wherein a first slot ( 601 ) is located on a movement direction of the first lock element ( 501 ) and allows the first lock element ( 501 ) to be inserted therein; and wherein a second slot ( 602 ) is located on the a movement direction of the second lock element ( 502 ) and allows the second lock element ( 502 ) to be inserted therein.

6 . The door lock mechanism ( 1 ) according to claim 5 , wherein the first lock element ( 501 ) and the second lock element ( 501 ) are located parallel to each other with a distance therebetween, thus preventing the first lock element ( 501 ) from entering the second slot ( 602 ) and the second lock element ( 502 ) from entering into the first slot ( 601 ); and wherein the sliding element ( 8 ) has a curved form, with the first lock element ( 501 ) on one end and the second lock element ( 502 ) on the other end.

7 . The door lock mechanism ( 1 ) according to claim 1 , comprising:
an extension ( 14 ) on the lock element ( 5 ) which enables the lock element ( 5 ) to be connected to the sliding element ( 8 ); and a cavity ( 15 ) on the sliding element ( 8 ), which allows the extension ( 14 ) to move therein, thus allowing the movement of the lock element ( 5 ) on the inclined surface ( 13 ).

8 . The door lock mechanism ( 1 ) according to claim 1 , wherein the door ( 2 ) has an open position (O) in which, when the lock element ( 5 ) is in the free position (F), the door ( 2 ) moves on the rail ( 4 ) to be positioned to form an opening on the body (G) and is fixed by moving the lock element ( 5 ) to the locked position (L).

9 . The door lock mechanism ( 1 ) according to claim 7 , comprising at least one spring ( 16 ) which surrounds the extension ( 14 ) and which is compressed by a pressure force applied thereon when the door ( 2 ) is moved from the locked position (L) to the free position (F), thus allowing the lock element ( 5 ) to be removed from the slot ( 6 ).

10 . The door lock mechanism ( 1 ) according to claim 9 , comprising a compression element ( 17 ) that enables the spring ( 12 ) on the door ( 2 ) to be compressed; wherein the extension ( 14 ) on the lock element ( 5 ) is passed through an opening of the compression element ( 17 ) so as to be placed in the cavity ( 15 ); and wherein the extension ( 14 ) moves in the cavity ( 15 ) such that the compression element ( 17 ) applies a pressure onto the spring ( 16 ) in order to store energy.

11 . The door lock mechanism ( 1 ) according to claim 1 , comprising a plurality of rods ( 18 ) triggered by rotational movement of the handle ( 3 ) for transferring movement of the handle ( 3 ) to the transfer elements ( 7 ), thus enabling the transfer element ( 7 ) to perform a simultaneous rotational movement with the handle ( 3 ).

12 . The door lock mechanism ( 1 ) according to claim 5 , comprising:
a first rail ( 401 ) located between the door ( 2 ) and the body (G), on a side of the door ( 2 ) that has the minimum distance from the air vehicle base (T); a second rail ( 402 ) located on the other side of the door ( 2 ) opposite the first rail ( 401 ), with a distance to the air vehicle base (T) greater than that of the first rail ( 401 ); and wherein the door ( 2 ) is almost completely prevented from moving in the locked position (L) by being fixed on both rails ( 4 ) by means of the first lock element ( 501 ) and the second lock element ( 502 ) that are placed simultaneously in the slots ( 6 ) on the first rail ( 401 ) and the second rail ( 402 ) with only a handle ( 3 ) movement.

13 . The door lock mechanism ( 1 ) according to claim 3 , wherein the frame ( 12 ) forms a section of a circle covering an angle value predetermined by a user with the fastener ( 9 ) being centered.

14 . The door lock mechanism ( 1 ) according to claim 1 , wherein the door ( 2 ) slides on the rail ( 4 ).
