The present invention relates to handles for a vehicle door, also called “flush handles”.
Handles for vehicle doors are components having a significant influence on the style of vehicles. In this respect, vehicle manufacturers often seek to arrange the handle in the plane of the door so that it occupies a flush position also called a flush arrangement. A flush handle generally renders the handle as invisible as possible. Such flush door handles also have the advantage of reducing the aerodynamic noise caused by the rush of air as the vehicle is being driven along.
A flush handle has been proposed with a grip member and a moveable flap configured to be moved by a user to grab the grip member and pull the grip member to open the vehicle door.
Such a handle requires an arrangement with additional pieces including means for maintaining the flap so as to avoid movements of the flap when the car is moving.
Moreover, such a handle turns out inconvenient in use as the user needs to make preliminary movements to have access to the grip member. Indeed, there is a need of a handle wherein the grip member is moved to an active position to be grabbed, to limit the preliminary movements of the user.
An object of the invention is to propose a flush handle where a flap is not needed, and wherein the preliminary movements of the user are reduced.
To this end the invention relates to a handle for a vehicle door, comprising:
Advantageously, the flush handle of the invention has a simple arrangement in which a flap is not needed, thereby making the handle more convenient to use.
According to further embodiments which can be considered alone or in combination:

The activation switch 60 is part of an activation circuit (not represented) which indicates the contact between the activation member 2 and the arm 34a.
The handle may further comprise one or more motor switches configured to indicate the rotational state of the activation member 2. To this end, the motor switches are part of a motor circuit (not represented).
The switches may also inform the driving mechanism that opening is exerted and trigger an operation of the motor in the opposite sense such that the grip member 3 may return to the flushing position.
Referring to
The grip lever 32a has a single arm 33a connected to the gripping part 31.
In the second embodiment, the flushing position is shown in
In the second embodiment, the actuator lever 4 cooperates with the gripping part 31 to drive the grip member 3 from the flushing position to the active position. More particularly, the actuator lever 4 comprises an actuator return means 42 which is a spring 42, configured to drive the actuator lever 4 which in turn drives the grip member 2, in particular the gripping part 31 such that the grip member 3 from the flushing position to the active position.
In this regard the actuator lever 4 comprises a driving structure 43a, which is a protuberance, and the gripping part 31 comprises a driven structure 33c which is a recess in which the driving structure 43a is engaged.
The actuator lever 4 comprises a shaft extending along and between two shafts forming a frame of the gripping part 31.
The actuator shaft is rotationally mounted about an actuator axis 40, and the grip member is rotationally mounted about a grip axis 30 substantially parallel to the actuator axis 40.
The grip member 3 is spring biased towards the flushing position. A grip spring 32 is provided to this end.
In the second embodiment, the grip member 3 is urged towards the active position by the actuator spring 42 through the actuator lever 4 and the driving and driven structures 43a and 33a. The actuator spring has a force overcoming the grip spring when the actuator is driving the grip member 3.
The arrangement of the actuator lever 4 of the second embodiment may comprise a retaining means 5a which is a bistable spring mechanism connected to the actuator lever 4 and to a bracket. The bistable spring mechanism being movable between a retaining state in which the actuator lever 4 is retained in a first position, and a releasing state in which the actuator lever 4 is released from the first position to move to a second position.
A spring based actuator lever 4 and retaining means 5a is a mechanical arrangement of the actuator lever. Advantageously, a mechanical arrangement is usable when there is no battery in the vehicle, and a user may access the vehicle.
The actuator lever 4 is moveable between a rest position and an activating position.
The rest position is shown in
When the actuator lever 4 is in the rest position, and the gripping part 31 is pressed from outside the vehicle, the actuator lever 4 is also pressed by means of the driven and driving structures 33a and 43a so as to make the retaining means release the actuation lever 4 to move towards the activating position. This movement is shown by reference 4c in
The actuator lever 4 further comprises a first locking structure 41a opposite to the driving structure 43a with respect to the actuator axis 40. The grip member 3 comprises a second locking structure 31a opposite to the driven structure 33a with respect to the grip axis 40.
The locking structures are configured such that when the grip member is moved from the active position to the opening position the second locking structure 31a drives the first locking structure 41a such that the actuator lever is driven towards the rest position, and presses the retaining means so as to be retained in the rest position.
In operation, when the grip member 3 is in the flushing position, the user wanting to open the corresponding vehicle door pushes the gripping part 31 such that the driven structure 33a drives the driving structure 43a which in turn pushes the bistable spring mechanism. The actuator lever 4 is then released from the rest position and the actuator spring 42 drives the actuator lever 4 and thus the grip member 3 toward the opening position. This is made possible through the driving and driven structures 43a and 33a, and the force of the actuator spring 42 overcoming the force of the grip spring 32.
When the grip member 3 is in the active position, the user may pull the gripping part 31 according to an opening direction 11 toward the open position such that first locking protuberance 31a drives the second locking protuberance 41a so as to drive the actuator lever 4 towards the rest position, and also make the actuator lever 4 press the retaining means 5 to make the retaining means 5 retain the actuator lever 4 in the rest position. This movement is shown in
With the actuator lever retained in the rest position, the grip member 3 is free to return to the flushing position to the grip return means 32.
Referring to
The grip member 3 has a plane shape with projections for a column 34 and for a locking structure 31a detailed below.
In the third embodiment, the flushing position is shown in
In the third embodiment, the actuator lever 4 cooperates with the grip member 3 to block the grip member 3 from the flushing position. To this end, the grip member 3 comprises a first locking structure 31a and the actuator lever 4 comprises a second locking structure 41a cooperating with the first locking structure 31a.
The actuator lever 4 is moveably mounted between a locking position and an unlocking position.
In the locking position, the actuator lever 4 blocks the grip member 3 in the flushing position by means of the locking structures 31a and 41a.
In the unlocking position, the actuator lever 4 enables the grip member 3 to move towards the active position.
The actuator return means 42, which is a spring, is configured to drive the actuator lever 4 towards the locking position.
The retaining means 5 are configured to retain the actuator lever 4 in the locking position.
More particularly, the first locking structure 31a defines a first trajectory T1 when the grip member 3 is moved from the flushing position to the active position, and in the locking position, the second locking structure 41a blocks the first locking structure 31a so as to block the grip member 3 in the flushing position.
When the actuator lever 4 is moved to the unlocking position, the second locking structure 41a is moved out of the first trajectory T1 of the first locking structure 31a.
The grip member further comprises a driving structure 33 and the actuator lever 4 comprises a driven structure 43 cooperating with the driving structure 33 as shown in
A bistable spring arrangement comprises a linear spring 51 on a first past and a retaining path 54 on a second part of the handle. The linear spring 51 may be attached to a bracket 1 of the handle and the retaining path 54 may be provided on the actuator lever 4 as shown in
The linear spring is urged between two positions in the retaining path 54 as the first and second parts are pressed with respect to each other.
More particularly, when the grip member 3 is in the flashing position and the gripping part is pressed from outside the door, the driving protuberance 33 drives the driven protuberance 43 such that the actuator lever 4 presses the retaining means 5 which in turn releases the actuator lever 4 from the locking position. This movement is shown in
When the grip member is in the active position and is moved to the opening position, the first locking structure 31a cooperates with the second locking structure 41a so as to drive the actuator lever 4 along a second trajectory T2 such that the actuator lever 4 presses the retaining means 5 which in turn releases the actuator lever 4 from the unlocking position.
The actuator lever 4 comprises a shaft rotationally mounted about an actuator axis 40, and the grip member is rotationally mounted about a grip axis 30 substantially parallel to the actuator axis 40.
The grip member 3 is spring biased towards the active position. A grip spring 32 is provided to this end.
In the third embodiment, the actuator spring 42 drives the actuator lever towards the locking position. The actuator spring 42 has a force overcoming the grip spring 32 such that the grip member remains in the flushing position.
In operation, when the user pushes the grip member 3 and the bistable spring mechanism, the user overcomes the force of the actuator spring 42 such that the actuator lever 4 is moved from the locking position to the unlocking position. The actuator lever is then retained in the unlocking position by the retaining means 5. Such a retaining overcomes the force of the actuator spring 42.
With the actuator lever 5 retained in the unlocking position, the second locking structure 41a is moved out of the first trajectory T1 of the first locking structure 31a. The first locking structure is then free to move according to the first trajectory so that the grip member is moved from the flushing position to the active position, by means of the grip return means 32.
When the grip member 3 is in the active position, the user may pull the gripping part 31 according to an opening direction 11 toward the open position such that first locking protuberance 31a drives the second locking protuberance 41a according to a second trajectory 41 such that the actuator lever 4 presses the bistable spring mechanism which releases the actuator lever 4 to move towards the locking position, by means of the force of the actuator spring 42. This movement is shown by
The grip member 3 also moves towards the flushing position as the force of the actuator spring 42 overcomes the force of the grip spring 32.
When the grip member 3 is in the active position, the user may also push the gripping part 31 towards the flushing position such that driving protuberance 33 drives the driven protuberance 43 and such that the actuator lever 4 presses the bistable spring mechanism which releases the actuator lever 4 to move towards the locking position, by means of the force of the actuator spring 42. This movement is shown by
The grip member 3 is maintained in the flushing position as the force of the actuator spring 42 overcomes the force of the grip spring 32.
