Abstract

An actuating apparatus for a door lock of a vehicle door, in particular as part of a door handle arrangement of a vehicle door, wherein the actuating apparatus has a handle part that is grippable by a hand and is configured in order to be transferable between a resting position and a ready position, and wherein the handle part is manually movable from the ready position into an actuating position and is in particular pivotably or linearly extendable, wherein the actuating apparatus is configured in order to actuate the door lock when the handle part reaches or has reached the actuating position. The actuating apparatus has a blocking and/or delay mechanism, which cooperates with the handle part such that the handle part is transferable from the ready position back into the resting position only with a time delay and/or only in an at least partially braked or dampened manner.

First claim

The invention claimed is:

1. An actuating apparatus for a door lock of a vehicle door, wherein the actuating apparatus has a handle part that is grippable by a hand, wherein the handle part is configured in order to be transferable between a resting position and a ready position, and wherein the handle part is manually movable into an actuating position proceeding from the ready position and is pivotably or linearly extendable, wherein the actuating apparatus is configured in order to actuate the door lock when the handle part reaches or has reached the actuating position,
wherein the actuating apparatus has a blocking and/or delay mechanism, which cooperates with the handle part such that, during a return movement, the handle part is transferable from the ready position back into the resting position only with a time delay and/or only in an at least partially braked or dampened manner;
wherein the blocking and/or delay mechanism has a control element;
wherein the control element is pivotably mounted about a first pivot axis relative to the handle part, wherein the handle part is pivotably mounted relative to the vehicle door about a second pivot axis extending parallel to the first pivot axis, wherein the control element is coupled or operatively connected to the handle part via a gear element or a gear mechanism such that, during a pivoting movement of the handle part about the second pivot axis in order to transfer the handle part from the resting position into the ready position, the control element is transferred from a starting position into a ready position by way of a pivoting of the control element about the first pivot axis;
wherein the control element is designed at least in regions as a cam disk, wherein the cam disk is configured in order to interact with the handle part at least during the return movement of the handle part from the ready position back into the resting position in such a way that a non-uniform sequence of movement is compelled upon the handle part such that, initially during the return movement of the handle part, in a predetermined or determinable period of time, the non-uniform sequence of movement of the handle part is delayed in comparison to a subsequent sequence of movement of the handle part.

2. The actuating apparatus according to claim 1 ,
wherein the blocking and/or delay mechanism is configured in order to compel the non-uniform sequence of movement upon the handle part from the ready position back into the resting position on a purely mechanical basis during the return movement of the handle part.

3. The actuating apparatus according to claim 1 ,
wherein the blocking and/or delay mechanism has a damping device that acts in a motion-dampening or motion-braking manner upon the return movement of the handle part at least temporarily during the return movement of the handle part from the ready position back into the resting position;
wherein the blocking and/or delay mechanism is configured such that the damping device enters, at least temporarily, into an operative connection with the handle part only from a predetermined or determinable position of the handle part in order to act upon the return movement of the handle part in a motion-damping or motion-braking manner.

4. The actuating apparatus according to claim 1 ,
wherein a manipulator is associated with the door lock, said manipulator being transferable between a released position in which the door lock is unlocked and a neutral position in which the door lock is locked, wherein the manipulator associated with the door lock is configured such that it interacts with the control element in its released position, wherein, in the neutral position of the manipulator, the interaction with the control element is suspended.

5. The actuating apparatus according to claim 4 ,
wherein the manipulator associated with the door lock is configured such that it permits, in its released position, the transfer of the control element from the starting position into the ready position but blocks a pivoting or rotating movement of the control element about the first pivot axis that is necessary for the transfer of the control element from the ready position back into the starting position.

6. The actuating apparatus according to claim 1 ,
wherein the gear element or the gear mechanism is configured in order to, upon or after reaching the ready position of the control element, suspend or at least interrupt the coupling or operative connection between the control element and the handle part such that, during a pivoting movement of the handle part about the second pivot axis caused in order to transfer the handle part from the ready position into the actuating position, the control element is not further and/or no longer pivoted about the first pivot axis,
wherein the gear element or the gear mechanism is further configured in order to hold the control element in the ready position when the handle part is further pivoted out of the ready position into the actuating position and vice versa upon or after reaching the ready position of the control element; and/or
wherein the gear element is configured as a gear element of a slotted control system, or the gear mechanism is configured at least partially as a slotted control system, wherein the slotted control system has a slotted guide in the form of a slotted guide surface, which is configured in order to forcefully guide a slotted region of the handle part, said region being associated with the slotted control system and operatively connected to the handle part, according to the slotted guide.

7. The actuating apparatus according to claim 1 ,
wherein the cam disk has a non-uniform edge region, and wherein the handle part has a lever region fixedly connected to the handle part, which region is configured in order to pick up the movement the non-uniform edge region of the cam disk resulting from a rotation of the cam disk about the first pivot axis during a movement of the control element from the ready position into the starting position, such that the sequence of movement of the handle part is controlled by the control element accordingly during a movement of the handle part from the ready position into the starting position;
wherein the blocking and/or delay mechanism is configured such that a contact between the lever region of the handle part and the non-uniform edge region of the cam disk is suspended upon or after reaching the ready position of the control element.

8. The actuating apparatus according to claim 7 ,
wherein the lever region of the handle part has a guide roller or a guide wheel, via which a movement of the non-uniform edge region of the cam disk is picked up during the movement of the control element from the starting position into the ready position and back,
wherein the guide roller or the guide wheel is elastically mounted at least in regions in the lever region of the handle part, such that, when a predetermined or determinable critical force is applied to the guide roller or the guide wheel via the edge region of the cam disk, the roller or wheel can be pressed into the lever region, and/or
wherein the guide roller or the guide wheel is mounted at least in regions in the lever region and has an axis as well as an outer roller surface arranged coaxially and/or concentrically to the axis, said roller surface being connected to the axis elastically such that, when a predetermined or determinable critical force is applied to the guide roller or the guide wheel via the edge region of the cam disk, the outer roller surface of the guide roller or guide wheel can be pressed into the lever region at least in regions.
