  • the locking / unlocking control handles are often rotatably mounted about an axis orthogonal to the main plane of the leaf. It is therefore, for a user to perform two separate movements to lock / unlock and open or close such an opening. Thus, to open such an opening, a user must first turn the handle to unlock the door, then pull or push this handle orthogonally to the opening to open by rotating it around its axis.

  • An accumulator member according to the invention can be made in different ways: it can, for example, include a spring, magnets, a pneumatic cylinder, etc. Thus, the energy is not necessarily stored in mechanical form.
  • an operating member according to the invention is advantageously mechanically connected to said actuator in order to recharge the accumulator member during a closing movement, and by this single movement.
  • At least a portion of the movement travel of the operating member recharges the accumulator member energy.
  • the work provided by a user during the movement of the actuator on this portion of stroke is partially stored as potential energy in the accumulator member.

  • the invention does not have this disadvantage, thanks to the actuator which allows uncoupling the movement of the actuating member (from an open position to a closed position) of the locking mechanism.
  • the accumulator member accumulates the displacement energy of the operating member which is then in the ideal position for the closing maneuver, and the forces due to the user's push to close the door are not or little reported on the locking parts: only the energy stored by the accumulator member is exerted on these locking parts, and only during the closing time of the opening.
  • a device according to the invention thus makes it possible to avoid the sudden breaking of fragile parts, and in particular of the locking pieces, but also their mechanical wear over time.
  • storing energy in the accumulator member by a movement of the operating member between an open position and a closed position has the advantage of not storing this energy for a long time.
  • the invention allows to reload only when closing the opening. So that during the entire period during which the opening remains open, the accumulator member is discharged and does not exert pressure on potentially fragile parts or subject to creep.

  • the locking of the bolt (s) in the unlocked position keeps the energy stored in the actuator as the opening is not closed. Indeed, the bolt (s) being locked in position unlocked, the transmission chain between the actuator and the bolt (s) is also blocked and the actuator is not able to restore the energy for locking bolts until the locking means are not unlocked, that is to say as long as the wall detection means are not activated.
  • Such locking means can be made in different ways. For example, they advantageously comprise a part of the family of retainers such as a pin, a key, etc.
  • said operating member is mechanically connected to said locking mechanism, so as to be able to load said accumulator member during movement of the actuating member from an open position to a position closure.

Indeed in such a device, it is not necessary to keep the operating member in the open position until the end of the closing movement of the opening to be able to lock the opening on the jamb by the displacement the actuating member from an open position to a closed position. This has the effect of facilitating the closing of the opening. Indeed, the closing position of the operating member is more suitable for closing the opening.
  • the operating member is moved from an open position to a closed position by loading the organ accumulator in energy; secondly the opening closes; thirdly, when the opening is closed on the doorframe, the wall detection means are activated, the locking means are deactivated (that is to say, they no longer block the bolts in the unlocked position); fourthly, the released actuator locks the bolts using the energy stored by the accumulator member.
  • an accumulator member can accumulate energy and conserve stored energy regardless of the subsequent movement of the operating member (the actuator is reset).
  • said accumulator member is mechanically connected to the operating member via said transmission means, so that the accumulator member tends to return the operating member to a opening position.

Indeed, if, in step e, the operating member is released, the actuator releases the stored energy to return the operating member in the open position.
