Technical Field

The present invention relates to a handle arrangement for a door lock according to the preamble of claim 1.

Background

Handle devices for motor vehicle door locks are known from the prior art, as disclosed in DE 102014117005 a 1. The handle device comprises a manually operable handle element and a rotatably mounted transmission lever mechanically connectable to the door lock, said transmission lever being connected to the handle element and being rotatable by actuating the handle element with a first force.

Disclosure of Invention

It is an object of the present invention to provide a handle arrangement for a door lock which is improved over the prior art.

According to the invention, this object is achieved by a handle arrangement for a door lock having the features of claim 1.

Advantageous embodiments of the invention form the subject matter of the dependent claims.

A handle device for a door lock, in particular for a vehicle door lock, in particular for arrangement in the region of the outside of the door, comprises a manually actuatable handle element. According to the invention, a stop for limiting, in particular preventing, a movement of the handle element is provided, in particular for holding the handle element in, in particular, an undeflected rest position, wherein the stop can be overcome by actuating the handle element with a predetermined force in order to achieve a mechanical opening of the door lock.

In one possible embodiment, at least one spring element is provided, which is provided at least on the handle element and has a shaped portion which, in the rest position, is releasably engaged in the stop. In particular, the spring element is designed to be double-acting, wherein the spring element is arranged to act between the handle element and the handle recess in order to form a restoring element for the handle element, in particular for automatically restoring a manually actuated handle element back to its rest position, and wherein the spring element is arranged to act between the handle element and a stop in order to activate a mechanical emergency opening function and thus in particular to allow manual actuation of the handle element in case of an emergency.

In a further embodiment, the spring element has a shaped portion which is arranged to act between the handle element and the stop and to be releasably engaged in the stop in the rest position.

The handle device is provided in particular for a door lock to be opened electrically, wherein in the normal operation of the power opening of the door lock, it is ensured by the stop that the handle element advantageously does not move or only moves to the stop. In addition, the door lock can be opened mechanically by means of a handle element actuated with a predetermined force by the handle element to overcome the stop. In other words, the movement of the grip element and thus the activation of the mechanical emergency opening function is only allowed when a predetermined force, in particular a high force threshold, is reached. As a result, the emergency opening function is provided for such a door lock to be electrically opened, in order to allow mechanical opening of the door lock, in particular in an emergency in which the supply of electrical energy is lost.

The predetermined force is in particular greater, in particular many times greater, than the force required for actuating an electrical switching element provided on the handle device, in particular on the handle element, for the electrical opening of the door lock and/or the force required for moving the door, in particular the vehicle door, comprising the door lock when the door lock is opened. In this case, the force required to move the door is related in particular to the vehicle orientation allowed for normal vehicle operation of the vehicle. As a result, in normal operation it is ensured that the door lock opens only in a specified manner (i.e. electrically), and that the mechanical door opening is activated only in case of emergency. In this case, mechanical door opening is intuitively activated in the event of an emergency, because if the door lock cannot be opened electrically, the person wishing to open the door lock will intuitively pull harder on the handle element and thus apply a predetermined force when attempting to open the door, thereby mechanically opening the door lock.

The handle element is for example pivotably mounted on the handle recess. In this case, the handle recess is a member fixed to the vehicle, particularly to the door, in a mounted state of the handle device on the vehicle. In this case, the handle recess may, for example, be configured as a component to be mounted on a vehicle door or as a component of a vehicle door, in particular a door panel or door panel. The handle element is particularly pivotable about a substantially horizontal pivot pin, but may alternatively be pivotable, for example, also about a substantially vertical pivot pin or a differently oriented pivot pin. This may depend, for example, on the respective mounting position of the handle device on the door, in particular the vehicle door. The handle element is in particular designed as a flap which has to be engaged from the rear for actuation, in particular by engaging in a handle recess.

The stop is formed, for example, by at least one form-fitting connection, in particular a latching connection, of at least one spring element which can be detached, in particular can be disengaged, by actuating the grip element with a predetermined force and in particular the elastic deformation of the at least one spring element resulting therefrom. As a result, it is possible in a simple manner to fasten the handle element in the rest position and to pivot the handle element out of the rest position by actuating with a predetermined force. In this case, by means of the spring element, it is ensured that the form-fitting connection, in particular the latching connection, can be disconnected without the components of the handle device being damaged as a result, since the disconnection of the form-fitting connection, in particular the latching connection, is effected exclusively by elastic deformation of the at least one spring element. In particular, such a form-fitting connection, in particular a latching connection, can thus be formed again automatically when the handle element returns to the rest position, in particular by engagement of the at least one spring element.

In one possible embodiment, the at least one spring element is pressed against the handle element, in particular against the handle element, by the spring action of the spring element, and in the rest position of the handle element it is connected to, in particular engaged in, the handle recess by means of at least one form-fit connection, in particular a latching connection, such that the at least one form-fit connection is detachable, in particular disengageable, by actuating the handle element with a predetermined force and in particular the elastic deformation of the at least one spring element resulting therefrom. Thus, by means of the form-fit connection, in the rest position of the grip element, there is a connection between the grip element and the grip recess which holds the grip element in the rest position. When the handle element is actuated with a predetermined force, this form-fitting connection existing between the handle element and the handle recess by the spring element is broken, so that the handle element can be moved, in particular pivoted, relative to the handle recess.

Alternatively, it is also possible by the same action, for example, to realize that the at least one spring element bears against, in particular presses against, the handle recess by means of the spring action of the spring element, and in the rest position of the handle element the at least one spring is connected to the handle element by means of at least one form-fit connection, in particular a latching connection, such that the at least one form-fit connection is detachable, in particular disengageable, by actuating the handle element with a predetermined force and in particular an elastic deformation of the at least one spring element resulting therefrom.

The at least one spring element is configured, for example, as a leg spring, wherein the at least one spring leg bears against the handle element, in particular presses against the handle element, by means of the spring action of the spring element, and has a shaped portion which, in the rest position of the handle element, projects into an opening in the handle recess. The shaped portion thus forms a latching lug which engages into an opening formed as a latching recess. The above effects are achieved by the following processes: the handle element is held in the rest position by means of such a form-fitting connection, in particular a latching connection, between the handle recess and the handle element by means of the spring element until the handle element is actuated with a predetermined force, so that the form-fitting connection, in particular the latching connection, is realized in particular by elastic deformation of the spring element, for example of the shaped part and/or of the spring leg, and by the shaped part sliding out, i.e. disengaging, from the opening of the handle recess, in particular by this elastic deformation. By sliding out, in addition to the form-fit connection, there is also a force-fit connection, for example between the spring element and the handle recess, which is overcome by friction between the spring element and the handle recess.

Furthermore, it is also possible here, alternatively and with the same effect, for example, for the at least one spring leg to bear against the handle recess, in particular to press against the handle recess, by the spring action of the spring element, and for the shaped portion to project into the opening of the handle element in the rest position of the handle element.

In the above-described first alternative, in which at least one spring leg abuts against the handle element, for example, at least one further spring leg of the leg spring abuts against, in particular presses against, the handle recess by the spring action of said spring. The at least one spring element, which is in particular designed as a leg spring, thus simultaneously serves as a return spring for the handle element in order to return the handle element into the rest position again after having been pivoted out. In other words, the at least one spring element has a dual function, on the one hand by ensuring that the activated, i.e. actuated and pivoted-out handle element is restored to the rest position, and on the other hand, in particular by a shaped portion, i.e. by a corresponding contour, blocking the handle element in the rest position, i.e. holding the handle element in this rest position, on the at least one spring leg, until the predetermined force is reached. In particular, in this way, the implementation of the stop which is overcome only by actuating the handle element with a predetermined force can be achieved without additional components, since advantageously also a spring element for restoring the handle element from the pivoted-out position back into the rest position is used. Only a shaped portion on at least one spring leg of the spring element (which is configured as a leg spring) and a corresponding opening in the handle recess are required.

For example, an alternative possibility may be to use a correspondingly stronger return spring, so that a greater force for actuating the handle element is obtained solely by its return spring action. However, with such a more powerful return spring, a correspondingly high force consumption is required during the entire actuation of the handle element, i.e. over the complete pivoting path, in order to overcome the high return spring action of such a more powerful return spring.

In contrast to this, in the solution described herein, after overcoming the form-fitting connection by actuating the handle element with a predetermined force, a further pivoting path of the handle element requires a significantly lower force consumption, which is caused by the spring action that has to overcome the relatively weak spring element and by the friction generated by the spring leg that slides along the handle recess after its shaped part has been disengaged from the opening of the handle recess. The spring element used here can therefore be assembled in a simpler, more economical and easier manner than such a more powerful return spring. By the configuration of the at least one spring element, in particular its shape, wire diameter and/or leg length, the predetermined force can be set in a simple manner, i.e. the respective force with which the handle element is actuated in order to overcome the stop and to achieve mechanical opening of the door lock can be predetermined.

The leg spring is for example arranged on a pivot pin about which the handle element is pivotably mounted relative to the handle recess. Thereby ensuring a reliable mounting of the leg spring and its function as a return spring and stop.

For example, the handle element has two handle element legs and the handle recess has two handle recess legs, wherein the handle element legs are pivotable about a pivot pin which is mounted in the handle recess legs. In this way, for the leg spring, in particular for at least one spring leg of the leg spring, at least one bearing region is provided on the handle element by means of at least one handle element leg, and at least one region of the handle recess is also provided in which an opening is provided, wherein the spring leg can engage with its shaped part in this opening to form a form-fitting connection.

In one possible embodiment, the leg spring has two outer spring legs which in each case bear against one of the handle element legs and in each case have a shaped portion which in the rest position of the handle element projects into an opening of the respective handle recess leg, wherein the leg spring has at least one central spring leg which bears against the handle recess, in particular presses against the handle recess, by means of the spring action of the spring element. As a result, the stop is formed by two outer spring legs which engage with their respective shaped portions in one respective opening of the handle recess. In this way, by the action of the force on the grip element, in particular a one-sided movement of the grip element is avoided and it is ensured that the grip element is moved only by actuation with a predetermined force.

By means of the at least one central spring leg, the support of the spring element on the handle recess is ensured, in particular during the pivoting movement of the handle element, such that the spring element gradually tensions the element during the pivoting movement of the handle element, i.e. the pivoting movement of the handle element opposes the spring action of the spring element and increasingly tensions the spring element, such that a restoring action of the spring element on the handle element is ensured for a restoring movement of the handle element from the deflected position back into the rest position.

Alternatively, for example, two separate spring elements can be provided, which are configured as leg springs, wherein one spring leg of the respective leg spring bears against one of the handle element legs, in particular against the handle element leg, by means of the spring action of the spring element, and in each case has a shaped portion which, in the rest position of the handle element, projects into an opening of the respective handle recess leg, and the other spring leg of the respective leg spring, in particular the spring leg facing the respective other leg spring, bears against the handle recess, in particular against the handle recess, by means of the spring action of the spring element, in order to achieve the restoring action described.

Detailed Description

Fig. 1 and 3 show a door lock, not shown here, in particular for a vehicle, in particular for a handle device 1 arranged in the region of the outside of a door, which is in particular designed as a vehicle door. The handle device 1 comprises a handle recess 2 and a handle element 3, which handle element 3 is pivotably mounted on the handle recess 2 and can be actuated manually.

The handle device 1 is provided in particular with a door lock for power opening. In this case it is provided that in normal operation of the power opening of the door lock, the grip element 3 advantageously does not move, i.e. remains stationary with respect to the grip recess 2. In this normal operation, the opening of the door lock is performed, for example, by actuating an electrical switching element, not shown, on the handle device 1.

In addition, the door lock can be opened mechanically by means of the handle element 3 by the handle element 3 being moved, in particular pivoted. Fig. 1 shows the grip element 3 in an unmoved rest position or initial position. Fig. 3 shows the handle element 3 in a pivoted (i.e. deflected) position for mechanical opening of the door lock.

As already mentioned, the handle element 3 is pivotably arranged on the handle recess 2. For this purpose, the handle recess 2, in particular on its rear face, has two lateral handle recess legs 4, a pivot pin 5 for mounting the handle element 3. The grip element 3 has, in particular on its rear face, two lateral grip element legs 6, which are thereby pivotably mounted on this pivot pin 5. In this case, the handle element leg 6 is arranged between the two handle recess legs 4. The grip element leg 6 extends, for example, through an opening or in each case through an opening of the grip recess 2 from the rear of the grip element 3 to the rear of the grip recess 2, wherein the grip element 3 is arranged in the front region of the grip recess 2.

Fig. 2 and 4 show in each case a detailed view in the region of one of the handle element legs 6 and one of the handle recess legs 4 of the handle device 1, more particularly in the region of the right handle element leg 6 and handle recess leg 4, wherein fig. 2 shows the detailed view of fig. 1, i.e. the rest position of the handle element 3, and fig. 4 shows the detailed view of fig. 3, i.e. the deflected position of the handle element 3. The pivoting movement of the handle element 3 about the pivot pin 5 relative to the handle recess 2, which handle recess 2 is fixed in the mounted state to the door and in particular to the vehicle, is illustrated in fig. 4 by means of the pivot arrow SP.

Furthermore, the handle device 1 comprises a spring element 7, which spring element 7 is configured as a leg spring and has two outer spring legs 8 and a central spring leg 9. The leg spring is arranged on the pivot pin 5, i.e. the pivot pin 5 extends through the leg spring. The leg spring has a plurality of windings. The axial length of the wound part of the leg spring, including the central spring leg 9, corresponds in particular at least substantially to the spacing between the inner surfaces of the two handle element legs 6 facing each other.

The central spring leg 9 is designed here as a double spring leg 9 by bending back at the outer leg end. The two outer spring legs 8 bear in each case against one of the grip element legs 6, in particular against the respective grip element leg 6, by the spring action of the spring element 7, and the central spring leg 9 bears against the grip recess 2, in particular against a bearing element on the grip recess 2, or is fixed in this bearing element, by the spring action of the spring element 7. In this case, the support of the

spring legs

8,9 against the handle recess 2 and/or against the handle element leg 6 and the configuration of the spring element 7 configured as a leg spring, in particular the windings, are arranged such that pivoting of the handle element 3 from the rest position shown in fig. 1 into the deflected position shown in fig. 3 takes place against the spring action of the spring element 7, so that the spring element 7 is increasingly tensioned by pivoting of the handle element 3 into the deflected position. As a result, a restoring action of the spring element 7 is ensured on the grip element 3, i.e. the grip element 3 is automatically pivoted out of the deflected position into the rest position by the spring action of the spring element 7 and by the increasing spring force of the spring element 7. The spring element 7 thus forms a return spring for the grip element 3.

As mentioned above, it is provided that in normal operation of the power opening of the door lock, the grip element 3 advantageously does not move, i.e. the grip element remains stationary with respect to the grip recess 2. Thus, in order to prevent a pivoting movement of the grip element 3 during normal operation, a stop 10 is provided for limiting, in particular for preventing, a pivoting movement of the grip element 3, in particular for holding the grip element 3 in a rest position, wherein the stop 10 can be overcome by actuating the grip element 3 with a predetermined force to achieve mechanical opening of the door lock.

In other words, the pivoting movement of the handle element 3 is only allowed for the mechanical opening of the door lock and thus the mechanical emergency opening function is activated, when a predetermined force, in particular a high force threshold, is reached. As a result, such an emergency opening function is provided for such a door lock to be opened electrically, in order to allow mechanical opening of the door lock, in particular when the electrical opening of the door lock is no longer functional, in particular in an emergency situation due to a loss of electrical energy supply.

A sectional view of the region of one of the handle element leg 6 and the handle recess leg 4 is shown in each case, more particularly in fig. 5 to 7 of the region of the right handle element leg 6 and the handle recess leg 4, showing this stop 10 and its mode of operation. In this case, fig. 5 shows the handle element leg 6 and the handle recess leg 4 when the handle element 3 is arranged in the rest position and the stop 10 is in the active state, fig. 6 shows this stop 10 being overcome by actuating the handle element 3 with a predetermined force, and fig. 7 shows the handle element leg 6 and the handle recess leg 4 in a deflected position in which the door lock of the handle element 3 is mechanically opened after the stop 10 has been overcome.

In order to avoid additional components for producing the stop 10, which may be associated with greater weight, higher costs, more complex assembly and greater installation space requirements, in the example shown the stop 10 is produced by a spring element 7, which spring element 7 already serves as a return spring for the handle element 3 in order to move the handle element 3 from the deflected position shown in fig. 3 back into the rest position shown in fig. 1 as described above.

In order to produce the stop 10 which holds the grip element 3 in the rest position until a predetermined force is reached, the two outer spring legs 8 have in each case a shaped portion 11, in particular a profile, as shown in fig. 2, in particular according to the sectional view of fig. 5 in the example of the right-hand outer spring leg 8. The left hand outer spring leg 8 is constructed in a similar manner thereto. Furthermore, the handle recess legs 4 have in each case an opening 12, in particular a receptacle for receiving this shaped portion 11 of the respective outer spring leg 8. The shaped portions 11 of the respective outer spring legs 8 thus advantageously form latching lugs and the openings 12 in the respective handle recess legs 4 advantageously form latching recesses for engaging the respective latching lugs in the rest position of the handle element 3. In this case, the shaped portion 11 of the respective outer spring leg 8 is oriented in particular in the direction of the respective handle recess leg 4 and the opening in the respective handle recess leg 4 opens in particular in the direction of the respective outer spring leg 8 and thus in particular in the direction of the respective other handle recess leg 4.

In the rest position, also referred to as initial position, of the handle element 3, the shaped portion 11 of the respective outer spring leg 8 is arranged in the opening 12 of the respective handle recess leg 4, in particular engages therein, as shown in fig. 2 and 5. It is therefore advantageous to form a latching connection, in particular at least a form-fitting connection, between the respective outer spring leg 8 and the respective handle recess leg 4, and, as a result of the respective outer spring leg 8 abutting against the respective handle element leg 6, via the respective outer spring leg 8, such a form-fitting connection, in particular a latching connection, is formed between the respective handle element leg 6 and the respective handle recess leg 4 and thus between the fixed handle recess 2, in particular fixed to the door, and the handle element 3 by the respective outer spring leg 8.

The form-fit connection is broken by actuating the grip element 3 with a predetermined force. By this force acting on the handle element 3, which force is transmitted through the respective handle element leg 6 to the respective outer spring leg 8 abutting against the respective handle element leg 6, the spring element 7, in particular the respective outer spring leg 8, is gradually elastically deformed until the shaped portion 11 of the respective outer spring leg 8 is disengaged from the opening 12 of the respective handle recess leg 4.

Fig. 6 shows, by means of the movement arrow BP, the movement of the outer spring leg 8 due to the actuation of the handle element 3 with a predetermined force and the resulting initial pivoting movement of the handle element 3, wherein the shaped portion 11 of the outer spring leg 8 has almost completely disengaged from the opening 12 of the handle recess leg 4. This movement of the outer spring leg 8 takes place in particular at least substantially parallel to the axial direction of the pivot pin 5, in particular at least substantially in the direction of the other respective outer spring leg 8. In other words, during the pivoting movement of the handle element 3, the respective outer spring leg 8, in particular the shaped portion 11 thereof, slides out of the opening 12 in the respectively fixed handle recess leg 4 against the spring force of the spring element 7, which opening 12 is also referred to as a socket or latch socket. For this purpose, the high force threshold must be overcome by the handle element 3 being actuated with a predetermined force.

Fig. 7 shows the increased relative movement of the handle element leg 6 with respect to the fixed handle recess leg 4 permitted thereby, and thus the pivotal movement of the handle element 3 to the deflected position shown in fig. 3. As soon as the respective outer spring leg 8 is completely disengaged, the respective outer spring leg 8 slides on the wall of the handle recess 2, in particular on the wall of the respective handle recess leg 4, resulting in no further increase in force.

Fig. 4 again shows the pivoting movement of the handle element 3 relative to the handle recess 2 and the resulting resilient movement of the spring element 7, in particular of the outer spring leg 8, which results in the shaped portion 11 of the outer spring leg 8 sliding out of the opening 12 of the handle recess leg 4, i.e. for disengaging the outer spring leg 8, in particular its shaped portion 11, from the opening 12 of the handle recess leg 4 and thus overcoming the stop 10.

The sliding of the shaped portion 11 of the respective outer spring leg 8 out of the opening 12 of the respective handle recess leg 4 is facilitated in particular by the shaped portion 11 of the respective outer spring leg 8 being configured as arcuate, curved and/or rounded, i.e. not as a sharp-edged latching lug but as a curved, arcuate and/or rounded latching lug, in particular by a corresponding bending of the spring wire of the spring element 7, whereby by such a curved, arcuate and/or rounded configuration of the sliding profile, the sliding profile can slide along the edge of the respective opening 12 without becoming jammed thereon. The predetermined force which has to be applied in order to overcome the stop 10 is thus influenced in particular by the spring action of the spring element 7, in particular by the force which is required to deform the respective outer spring leg 8 sufficiently to move the shaped portion 11 of the respective outer spring leg 8 out of the opening 12 of the respective handle recess leg 4.

By sliding the shaped portion 11 over the edge of the respective opening 12, the respective friction must also be overcome, so that the stop 10 is formed by the form-fit connection between the respective outer spring leg 8 and the respective handle recess leg 4 via the shaped portion 11 of the respective outer spring leg 8 and the opening 12 of the respective handle recess leg 4 and additionally via the friction resulting from the force-fit connection between the respective outer spring leg 8 and the respective handle recess leg 4.

By the configuration of the spring element 7, in particular its shape, wire diameter and/or leg length, in particular the leg length of the respective outer spring leg 8, the predetermined force required to overcome the stop 10 can be adjusted in a simple manner, i.e. by a corresponding configuration of the spring element 7, the corresponding force required to actuate the grip element 3 can be predetermined in order to overcome the stop 10 and to achieve mechanical opening of the door lock.

Thus, with the described solution, a semi-fixed handle element 3 is achieved, i.e. which is fixed in normal operation and is used for the electrical opening of the door lock, in particular by actuation of an electrical switching element without movement of the handle element 3, and can only be moved when a predetermined force, in particular a high force threshold, is reached, whereby the mechanical emergency opening function of the door lock can be activated.

This is allowed by the double-acting spring element 7, which on the one hand ensures the return of the actuated and deflected handle element 3 into the rest position and on the other hand prevents the handle element 3 from being moved by the shaped portion 11 on the respective outer spring leg 8, which shaped portion 11 engages in the opening 12 of the respective handle recess leg 4 in the rest position of the handle element 3 until the predetermined force is reached, and then releases the movement by disengaging the shaped portion 11 of the respective outer spring leg 8 from the opening 12 of the respective handle recess leg 4. Subsequently, only the spring force, in particular the restoring spring force of the increasingly tensioned spring element 7, and the friction force, which is generated, for example, by the sliding of the respective outer spring leg 8 along the respective handle recess leg 4, must be overcome for pivoting the handle element 3 into the biased position.

Thus, a simple, cost-effective spring element 7 can be used which is easy to assemble and relatively weak, i.e. has a relatively low spring action, whereby further pivoting movement of the handle element 3 is not impeded to a large extent after application of the predetermined force and after disengagement of the resulting shaped portion 11 of the respective outer spring leg 8 from the opening 12 of the respective handle recess leg 4. Thus, only a single application of a relatively large predetermined force is required to overcome the stop 10 formed by the engaged spring element 7, in particular by the respective shaped portion 11 engaged in the respective opening 12, and then, even after disengagement of the spring element 7, in particular after disengagement of the respective shaped portion 11 from the respective opening 12, normal actuation of the handle element 3 can mechanically open the door lock with a smaller force, in particular a force substantially smaller than the predetermined force required to overcome the stop 10 in the manner described.
