Abstract

This invention concerns mainly a handle system with two locking latches (7,8) called “self-locking”, independent one from the other for locking, but fitted with a single unlocking paddle (6). This system is fitted with indicators, which:

• • detect the door'"'"'s opening and closing and
  • indicate separately the locking of the two latches (7, 8).

Claims

1. A handle system intended to be attached to a door, which comprises:

a handle body;

an unlocking paddle able to turn about an axis of rotation to change the door from a closed position to an open position and vice versa;

two locking latches that can change from a locked position, wherein the latches cooperate with openings realized in the door, to an unlocked position wherein these latches are disengaged from the openings in the door, where these latches can be actuated by the unlocking paddle;

Further comprising;

first mechanical means for detecting the locking or unlocking of the locking latches and

second mechanical means for detecting the opening and closing of the door, independently of the first mechanical means.

2. The handle system according to claim 1, wherein the first mechanical means consist of indicators associated with the latches used in combination with transparent windows.

3. The handle system according to claim 2, wherein the second mechanical means comprise in particular a detection finger cooperating with the unlocking paddle, with this finger being able to cover the latches'"'"' indicators when the door is in the open position.

4. The handle system according to claim 3, wherein the detection finger is able to keep the unlocking paddle in a raised position in relation to the handle body.

5. The handle system according to claim 3, wherein

the two locking latches and the detection finger are mobile in translation in relation to the handle body along a direction substantially parallel to the axis of rotation of the unlocking paddle;

the two latches and the detection finger are connected with the handle body by means of a return spring, which tends to push these elements in a direction that corresponds to the latches'"'"' locked position.

6. The handle system according to claim 5, wherein the detection finger return spring has a stiffness constant greater than that of the springs associated with the latches.

7. The handle system according to claim 3, wherein the extremity of the detection finger has a V-shaped cross section, this extremity being able to cooperate with the unlocking paddle to keep it in the raised position.

8. The handle system according to claim 5, wherein the extremity of the detection finger cooperates with an interface of the door that forms and angle (α

) of 25 to 60 degrees with the extension plane of the handle body, when the door is in the closed position, so as to apply a residual force greater than the weight of the door.

9. The handle system according to claim 1, further comprising pilot holes made in the edges of the handle body, designed to receive centering studs attached to the door.
