Latch assembly
A latch assembly comprising an elongated flat latch slider slidable along a first axis between a first position and a second position in relation to a main latch, wherein the latch slider is provided with a protruding lug; a lock arrangement comprising; a body moving between a locking position and an unlocking position, wherein in the locking position a portion of the body is preventing movement of the lug along a path in parallel with said first axis, and in the unlocking position the lug can be moved along said first axis; and an electrically powered device connected to the body for moving the body between the locking position and the unlocking position.
1. A latch assembly comprising an elongated flat latch slider slidable along a first axis between a first position and a second position in relation to a main latch, wherein the latch slider is provided with a protruding lug;
a lock arrangement comprising:
a lock key being rotatable between a locking position and an unlocking position, wherein in the locking position a portion of the lock key engaging the lug and preventing movement of the lug along a path parallel with said first axis, and in the unlocking position the lug being movable long said first axis; and
an electrically powered device connected to the lock key for moving the lock key between the locking position and the unlocking position;
wherein the latch slider at a first end is provided with a standing grip portion and at a second opposite end is provided with a slider extension, the standing grip portion has an elongated weakening aperture defined therein, wherein the standing grip portion will break along the elongated weakening aperture when exerted on by high forces.
2. The latch assembly of claim 1 , wherein the lug of the latch slider extends through an elongated slot in the main latch, wherein a length of the elongated slot is sufficiently long to receive the lug when sliding the latch slider between the first position and the second position.
3. The latch assembly of claim 1 , wherein the latch slider at a first end is provided with a standing grip portion and at a second opposite end is provided with a slider extension.
4. A latch assembly comprising an elongated flat latch slider slidable along a first axis between a first position and a second position in relation a main latch, wherein the latch slider is provided with a protruding lug;
a lock arrangement comprising:
a lock key moving between a locking position and an unlocking position wherein in the locking position a portion of the lock key preventing movement of the lug along a path in parallel with said first axis, and in the unlocking position the lug being movable along said first axis; and
an electrically powered device connected to the lock key for moving the lock key between the locking position and the unlocking position;
wherein the latch slider at a first end is provided with a standing grip portion and at a second opposite end is provided with a slider extension, the standing grip portion has an elongated weakening aperture defined therein, wherein the standing grip portion will break along the elongated weakening aperture when exerted on by high forces.
5. The latch assembly of claim 2 , wherein the main latch is provided with a protruding element adjacent to and extending along the elongated slot and facing the protruding lug at least in the first position of the latch slider.
6. The latch assembly of claim 1 , wherein the electrically powered device comprises an electric motor connected to the body for rotating the body between a first locked position where at least a section of the rotating body is positioned in the path for preventing movement of the latch slider along the path, and a second unlocked position where no section of the rotating body is placed in the path.
7. The latch assembly of claim 5 , wherein the protruding element of the main latch is provided with an opening sufficient wide to receive a section of the rotating body in the locked position.
8. The latch assembly of claim 5 , wherein the protruding element of the main latch has a length substantially corresponding to the length of the elongated slot.
9. The latch assembly of claim 1 , wherein the electrically powered device comprises an electromagnetic unit connected to the body for extending and retracting the body in a direction perpendicular to the first axis, and wherein the protruding lug is provided with a locking aperture for receiving the body in the locked position.
10. The latch assembly of claim 5 , wherein the protruding element of the main latch has a length substantially corresponding to the length of the elongated slot.
11. The latch assembly of claim 1 , wherein the latch slider has a flat upper side and the protruding lug is a bent section of the latch slider formed as a flange extending substantially perpendicular to the flat upper side.
12. The latch assembly of claim 5 , wherein the protruding element of the main latch is a bent section of the main latch formed as a flange extending substantially perpendicular from the main latch.
13. The latch assembly of claim 1 , wherein a spacer ring mounted on a bolt is received in an elongated aperture in the latch slider to stabilize the sliding movement of the latch slider.
14. The latch assembly of claim 1 , wherein the main latch has a rear latch flange and a forward latch flange, the rear and forward latch flanges having a free space defined therebetween for receiving the lock key.
