Description

vehicle comprising such a locking arrangement TECHNICAL FIELD The present invention relates to a locking arrangement for an entrance of avehicle and a vehicle comprising such a locking arrangement. More specificallythe present invention relates to a locking arrangement for a ballistic vehiclecab, allowing movement of manipulators independently of each other.

BACKGROUND Ballistic vehicle cabs typically comprise very sturdy locking arrangements onthe doors in order to withstand the forces that the cab may be exposed to. Alocking arrangement for a vehicle typically comprises an inside door handleand an outside door handle connected to each other. The locking arrangementalso comprises a locking mechanism which may be electronically connected tothe door handles. By actuating/rotating any of the door handles, the lockingmechanism may be deactivated and the door can be opened. The lockingarrangements are used to keep the doors shut during operation of the vehicleand when the vehicle is parked. The locking arrangement may be configureddifferently depending on the desired functionality of the locking arrangement. ltmay for example be desired to be able to open the doors from the outside, for example in an emergency situation.

Document US6523376 B2 discloses a lock for motor vehicle doors, which iselectrically operable and has an additional mechanical transmission foremergency opening in case of failure of electric current supply or similar.Document US6112564 A discloses a lock for motor vehicle doors allowing thelock and thus the door to be actuated or opened by each door handle. The lockalso allows a child-proof state where actuation of the outside door handle canopen the door but the inside door handle cannot.

SUMMARY OF THE INVENTION Despite known solutions in the field, it would be desirable to develop a lockingarrangement for an entrance of a vehicle, which alleviates or at least reducesdrawbacks with prior art.

An object of the present invention is thus to achieve an advantageous lockingarrangement, which enables deactivation of the locking mechanism and thusopening of the entrance from the inside at all times.

Another object of the invention is to achieve an advantageous lockingarrangement for an entrance of a vehicle, which locking arrangement increases safety.

The herein mentioned objects are achieved by a locking arrangement for anentrance of a vehicle and a vehicle comprising such an arrangement accordingto the independent claims.

Hence, according to an aspect of the present invention a locking arrangementfor an entrance of a vehicle is provided, the locking arrangement comprising: afirst manipulator; a second manipulator connectable to the first manipulator;and a locking mechanism mechanically connectable to the first and secondmanipulator, wherein the locking arrangement is configured such that rotationof the first manipulator and/or the second manipulator about a rotation axis, ina predetermined direction, deactivates the locking mechanism, wherein theconnection between the first manipulator and the second manipulatorcomprises a play in the rotational direction, allowing at least one of the first andsecond manipulator to rotate independently of the other manipulator. Theconnection between the first manipulator and the second manipulator may bereferred to as an interface, wherein the interface comprises a play in therotational direction, allowing at least one of the first and second manipulator torotate independently of the other manipulator.

The entrance associated with the Iocking arrangement may be a door, awindow, a hatch or similar, for getting access to the inside of a vehicle. For thesake of describing the Iocking arrangement the term “door” will be used hereinbut it is to be understood that this is only an example of an object that can be equipped with the Iocking arrangement.

The first manipulator may be referred to as a first door handle and the secondmanipulator may be referred to as a second door handle. The first manipulatormay comprise a first section rotatable about the rotational axis and the secondmanipulator may comprise a first section rotatable about the rotational axis.The manipulators are suitably adapted to be arranged, such that the firstsections of the manipulators are aligned. The first manipulator and the second manipulator thereby have a common rotational axis when being connected.

Suitably, the Iocking arrangement is configured such that when the firstmanipulator and the second manipulator each are in a normal non-actuatedstate, the Iocking mechanism is activated. The door is thereby retained in aclosed position. When the first manipulator or the second manipulator isactuated and thus rotated in the predetermined direction, the Iockingmechanism will be mechanically affected and at a predetermined angle ofrotation of the manipulator, the Iocking mechanism is deactivated and the dooris openable. By providing a relative play at the connection between the firstmanipulator and the second manipulator, such that at least one of themanipulators can rotate independently of the other, at least one manipulatorcan interact with the Iocking mechanism individually.

According to an example the connection between the first manipulator and thesecond manipulator comprises a play in the rotational direction, allowing boththe first and the second manipulator to rotate independently of each other. This way, both manipulators can interact with the Iocking mechanism individually and the Iocking mechanism may thereby be deactivated by means of one ofthe manipulators, without actuation/rotation of the other manipulator.

The first manipulator adapted to be arranged on the outside of the door and the second manipulator adapted to be arranged on the inside of the door. The first manipulator lockable by means of attaching a separate lock to the first manipulator. The first manipulator may forexample be lockable by means of a padlock. The first manipulator beinglockable means that actuation of the first manipulator can be prevented bymeans of a separate lock. ln some situations it may be desirable to be able toprevent rotation of one of the manipulators and thus prevent opening of thedoor by means of one of the manipulators. For example, it may be desirable toprevent unauthorized persons to enter the vehicle whereby the manipulator onthe outside of the door should be locked and prevented from being actuated.However, it may at the same time be desirable to be able to open the door bymeans of the other manipulator from the inside of the vehicle. By providing arelative play at the connection between the first manipulator and the secondmanipulator, such that at least one of the manipulators can rotateindependently of the other, the second manipulator can be actuated todeactivate the Iocking mechanism even when the first manipulator is lockedand physically prevented from being actuated. This way, a simple and reliable Iocking arrangement is achieved, which increases safety.

The Iocking mechanism may comprise multiple components, such as rotarylatches, Iocking wedges, gear wheels or similar. The configuration of theIocking mechanism is not per se relevant for the function of the invention aslong as it is mechanically connected to the first manipulator and the secondmanipulator according to the herein explained embodiments.

According to an embodiment the play at the connection between the firstmanipulator and the second manipulator corresponds to an angle of rotation for deactivating the locking mechanism. Thus, the play is configured to allow atleast one of the manipulators to rotate with an angle which deactivates thelocking mechanism, without rotation of the other manipulator. The angle ofrotation for deactivating the locking mechanism depends on the configurationof the locking mechanism and the connection between the locking mechanismand the manipulators. The play may correspond to an angle of rotation withinthe range of 40-50 degrees. The play may correspond to an angle of rotation of 45 degrees.

According to an embodiment the locking arrangement further comprises anintermediate part for connecting the first manipulator and the secondmanipulator, wherein the relative play between the first and secondmanipulator is formed by means of a recess in the intermediate part. Theintermediate part may thus constitute an interface between the first and thesecond manipulator. The first manipulator and the second manipulator maythus be connected via the intermediate part. The intermediate part may beessentially cylindrical with a cylinder wall and a through hole. The first sectionof the first manipulator and the first section of the second manipulator may beadapted to be inserted into the through hole of the intermediate part fromopposite directions. The intermediate part and the first sections of themanipulators are thus adapted to be coaxially arranged. When any of themanipulators is actuated the first section of the manipulator is rotated aboutthe rotational axis and will rotate the intermediate part in the same rotationaldirection. The intermediate part is adapted to be mechanically connected tothe locking mechanism, such that rotation of the intermediate part in thepredetermined direction deactivates the locking mechanism. The play may beachieved by a recess or groove in the cylinder wall of the intermediate part. Toachieve the play and thereby allow the first sections of the manipulators torotate independently of each other, the recess in the intermediate part mayextend along at least a part of the circumferential of the cylinder wall. Therecess of the intermediate part may thus have a first end and a second end in the circumferential direction. The recess may also extend along in a second direction along at least a part of the Iongitudinal direction of the intermediatepart. The recess in the intermediate part may be an opening in the cylinderwall. Thus, the intermediate part may have a cross-section which is essentiallyC-shaped.

According to an embodiment the first manipulator and the second manipulatorare rotationally attached to the intermediate part. Thus both manipulators canbe actuated individually to deactivate the locking mechanism without affectingthe other manipulator. The first sections of the first manipulator and the secondmanipulator respectively may each comprise a protrusion, extendingessentially perpendicularly to the rotational axis of the manipulators. Theprotrusions are adapted to be guided in the rotational direction in the recess ofthe intermediate part. The protrusions are thus adapted to follow the recess inthe circumferential direction when the manipulators are actuated. Rotating themanipulators, such that the protrusions move between the first and the secondend of the recess will not affect the intermediate part. However, when amanipulator is in a position where the protrusion has reached and abuts thefirst or the second end of the recess, rotation of the manipulator in direction ofthe end will cause the intermediate part to rotate together with the manipulator.Suitably, when the first and second manipulators are in a non-actuated state,the protrusions of the first sections of the manipulators are essentially abuttingthe first end of the recess. The first end of the recess may thereby prevent theprotrusion to move further in the predetermined direction inside the recess.Thus, when any of the manipulators is actuated and rotated in thepredetermined direction, the intermediate part will be rotated by the protrusionof the actuated manipulator abutting the cylinder wall. Because of the recess(play) in the intermediate part, when one manipulator is rotating theintermediate part, the protrusion of the other manipulator will no longer abutthe first end of the recess. Thus, the other manipulator will not rotate. However,when the intermediate part has been rotated such that the second end of therecess abuts the protrusion of the other manipulator, the intermediate part will rotate the other manipulator.

The intermediate part may be mechanically connected to the lockingmechanism. The intermediate part may comprise outer teeth or groovesadapted to engage with corresponding teeth or protrusions of a rack of thelocking mechanism. The rack is suitably connected to a lock bolt which in aretracted state unlocks the door and in an extended state locks the door.Alternatively, the intermediate part may be fixedly connected to a lock elementof the locking mechanism. When the manipulators are in the non-actuatedstate the intermediate part is suitably positioned such that the lock element isretained in a receiving element whereby the door is locked. When any of themanipulators are actuated and the intermediate part is rotated in thepredetermined direction, the lock element is pivoted about the rotational axisand is thereby removed from the receiving element. The door is thereby openable.

According to an embodiment the relative play between the first and secondmanipulator is formed by means of a recess in the second manipulator. Thefirst section of the second manipulator may comprise a connection portionsimilar to the intermediate part as described above. The connection portionmay thus be adapted to be mechanically connected to the locking mechanismin the same way as the intermediate part. However, in this embodiment thesecond manipulator is fixedly attached to the connection portion and the firstmanipulator is rotationally attached to the connection portion. Thus, theconnection portion may be essentially cylindrical with a wall and a hole for thefirst section of the first manipulator to be inserted into. The play may beachieved by a recess in the wall of the connection portion. The recess in theconnection portion may extend in a first direction along at least a part of thecircumferential of the wall. The recess of the connection portion may thus havea first end and a second end in the circumferential direction. The recess mayalso extend along in a second direction along a part of the longitudinaldirection of the connection portion. The recess in the intermediate part may bean opening in the wall. The first section of the first manipulator may comprise aprotrusion, extending essentially perpendicularly to the rotational axis of the manipulator. The protrusion is adapted to be guided in the rotational directionin the recess of the connection portion. Suitably, when the first and secondmanipulators are in a non-actuated state, the protrusion of the first manipulatoris adjacent or abuts the first end of the recess. The first end of the recess issuitably preventing the protrusion to move further in the predetermineddirection inside the recess. Thus, when the first manipulator is actuated androtated in the predetermined direction, the connection portion and thus thesecond manipulator will be rotated by the protrusion of the first manipulator.However, because of the recess (play) in the connection portion, if only thesecond manipulator is actuated the connection portion will rotate and theprotrusion of the first manipulator will no longer abut the first end of the recess.Thus, the first manipulator will not rotate. The second manipulator can thus beactuated and deactivate the locking mechanism independently of the firstmanipulator. This way, even when the first manipulator is prevented from beingactuated by means of a separate lock, the second manipulator can be used todeactivate the locking mechanism.

A vehicle comprising the herein described locking arrangement is alsoprovided. The vehicle may comprise a ballistic cab comprising the lockingarrangement. Ballistic vehicle cabs typically comprise very sturdy lockingarrangements on the doors in order to withstand the forces that the cab maybe exposed to. The locking arrangement according to the invention is amechanically simple and durable construction which is suitable for ballisticvehicle cabs.

The vehicle may be a hybrid vehicle comprising an electricmachine (not shown) in addition to a combustion engine (not shown). The vehicle cab 2 may be a ballistic cab.

Figure 2a-b schematically illustrate a locking arrangement 10 for an entrance 4of a vehicle 1 according to an embodiment of the invention. The locking arrangement 10 may be associated with a vehicle 1 as disclosed in Figure 1and is thus used for opening/closing an entrance 4 of the vehicle 1. ln thefurther description of the Iocking arrangement 10, the entrance 4 will bereferred to as a door.

The Iocking arrangement 10 comprise a first manipulator 12; a secondmanipulator 14 connectable to the first manipulator 12; and a Iockingmechanism 20 mechanically connectable to the first and second manipulator12, 14. The first manipulator 12 may be referred to as the first door handle,and the second manipulator 14 may be referred to as the second door handle.The Iocking arrangement 10 is configured such that rotation of the firstmanipulator 12 and/or the second manipulator 14 about a rotation axis A, in apredetermined direction D, deactivates the Iocking mechanism 20. Theconnection between the first manipulator 12 and the second manipulator 14comprises a play 40 in the rotational direction, allowing both the first and thesecond manipulator 12, 14 to rotate independently of each other. By providinga relative play at the connection between the first manipulator 12 and thesecond manipulator 14, such that they can rotate independently of the other,both manipulators 12, 14 can interact with the Iocking mechanism 20 individually.

The first manipulator 12 may comprise a first section 12” rotatable about the rotational axis A, and a second section 12” extending essentiallyperpendicularly to the first section 12”. At least a part of the first section 12” isadapted to be arranged inside the vehicle door 4. The second section 12” maybe configured as a lever or similar. However, the second section 12” may alsobe configured as a knob or similar. The second section 12” of the firstmanipulator 12 may be the part of the manipulator 12 which is manually manoeuvred by a person opening or closing the door 4.

The second manipulator 14 may comprise a first section 14” rotatable aboutthe rotational axis A, and a second section 14” extending essentially 11 perpendicularly to the first section 14”. At least a part of the first section 14” isadapted to be arranged inside the vehicle door 4. The second section 14” maybe configured as a lever or similar. However, the second section 14” may alsobe configured as a knob or similar. The second section 14” of the secondmanipulator 14 may be the part of the manipulator 14 which is manuallymanoeuvred by a person opening or closing the door 4.

The locking arrangement 10 further comprises an intermediate part 30 forconnecting the first manipulator 12 and the second manipulator 14. Theintermediate part 30 may comprise a recess 32 forming the relative play 40between the first and second manipulator 12, 14. ln this embodiment theintermediate part 30 is essentially cylindrical with a cylinder wall 36 and athrough hole 38. The first section 12' of the first manipulator 12 and the firstsection 14” of the second manipulator 14 may be inserted into the through hole38 of the intermediate part 30 from opposite directions. The first and thesecond manipulators 12, 14 are suitably arranged, such that the first sections12”, 14' of the manipulators 12, 14 are aligned. The first manipulator 12 andthe second manipulator 14 thereby have a common rotational axis A. Theintermediate part 30 is suitably mechanically connected to the lockingmechanism 20, such that rotation of the intermediate part 30 about therotational axis A, in the predetermined direction D, deactivates the lockingmechanism 20. The locking mechanism 20 may comprise multiplecomponents, such as rotary latches, locking wedges, gear wheels or similar.For the sake of clarity only the part of the locking mechanism 20 beingmechanically connected with the manipulators 12, 14 is shown. ln thisembodiment the intermediate part 30 comprises outer teeth or groovesadapted to engage with corresponding teeth or protrusions of a rack 22 of thelocking mechanism 20. When the intermediate part 30 rotates, theengagement of teeth will move the rack 22 linearly. The rack 22 is suitablyconnected to a lock bolt (not shown) which is in a retracted or extended statedepending on the position of the rack 22. ln the retracted state the door 4 is unlocked and in the extended state the door 4 is locked. 12 The recess 32 in the intermediate part 30 may be an opening in the cylinderwall 36, the opening extending along a part of the circumferential of thecylinder wall 36 and along at least a part of the longitudinal extension of theintermediate part 30. The longitudinal extension of the intermediate part 30 issuitably parallel with the rotational axis A. The recess 32 of the intermediatepart 30 may comprise a first end 32” and a second end 32”” in thecircumferential direction. ln this embodiment the first end 32” corresponds to afirst contact surface of the cylinder wall 36 and the second end 32””corresponds to a second contact surface of the cylinder wall 36.

The first section 12” of the first manipulator 12 and the first section 14” of thesecond manipulator 14 may each comprise a protrusion 50, 52, extendingessentially perpendicularly to the rotational axis A of the manipulators 12, 14.The protrusions 50, 52 may extend in parallel with the second sections 12””, 14””of the manipulators 12, 14. The protrusions 50, 52 follow the recess 32 of theintermediate part 30 in the circumferential direction when the manipulators 12,14 are actuated. The first end 32” of the recess 32 is suitably preventing theprotrusions 50, 52 to move further in the predetermined direction D inside therecess 32. The first end 32” may thus limit the recess 32 in the predetermineddirection D.

Figure 2a shows the first manipulator 12 and the second manipulator 14 in anormal non-actuated state, in which the locking mechanism 20 is activated. lnthe non-actuated state the protrusions 50, 52 of the manipulators 12, 14 areadjacent or abut the first end 32” of the recess 32. Rotation of any of themanipulators 12, 14 in the predetermined direction D will thereby essentiallyimmediately cause the intermediate part 30 to rotate together with themanipulator12, 14.

Figure 2b shows the first manipulator 12 in a fully actuated state. ln the fullyactuated state, the locking mechanism 20 is deactivated and the manipulator 13 12 cannot be further rotated in the predetermined direction D. By actuating thefirst manipulator 12, the protrusion 50 of the first manipulator 12 will apply aforce on the first end 32” of the recess 32 which rotates the intermediate part30. When the intermediate part 30 rotates, the first end 32” of the recess 32 willmove away from the protrusion 52 of the second manipulator 14 and becauseof the play 40, the second manipulator 14 will remain still. The recess 32 (theplay 40) is thus so large that the second end 32” of the recess 32 will not affectthe protrusion 52 of the second manipulator 14 when the first manipulator 12 isfully actuated. The play 40 formed by the recess 32 in the intermediate part 30suitably corresponds to an angle of rotation for deactivating the lockingmechanism 20. Thus, the play 40 allows one of the manipulators 12, 14 torotate with an angle which deactivates the locking mechanism 20, withoutrotation of the other manipulator 12, 14. The play 40 may correspond to anangle of rotation within the range of 40-50 degrees.

Only actuation of the first manipulator is illustrated in Figure 2b but it is to beunderstood that the locking arrangement 10 would function the same wayirrespectively of the manipulator 12, 14 being actuated.

Figures 3a-b schematically illustrate a locking arrangement 10 for an entrance4 of a vehicle 1 according to an embodiment of the invention. The lockingarrangement 10 is suitably configured as disclosed with regard to Figure 2aand Figure 2b, with the difference that the intermediate part 30 is fixedlyconnected to a lock element 24 of the locking mechanism 20. ln Figure 3a thefirst manipulator 12 and the second manipulator 14 are in a normal non-actuated state, in which the lock element 24 is retained in a receiving element26 of the locking mechanism 20. ln this state the locking mechanism 20 isactivated and the door 4 is thus locked. ln the non-actuated state theprotrusions 50, 52 of the manipulators 12, 14 are adjacent or abut the first end32” of the recess 32. Rotation of any of the manipulators 12, 14 in thepredetermined direction D will thereby cause the intermediate part 30 to rotatetogether with the manipulator 12, 14. 14 Figure 3b shows the first manipulator 12 in a fully actuated state. ln the fullyactuated state, the locking mechanism 20 is deactivated and the manipulator12 cannot be further rotated in the predetermined direction D. By actuating thefirst manipulator 12, the protrusion 50 of the first manipulator 12 will apply aforce on the first end 32” of the recess 32 which rotates the intermediate part30. When the intermediate part 30 rotates, the lock element 24 pivots aboutthe rotational axis A and is lifted out of the receiving element 26. The door is thereby unlocked.

Figure 4a-b schematically illustrate a locking arrangement 10 for an entrance 4of a vehicle 1 according to an embodiment of the invention. The lockingarrangement 10 may be associated with a vehicle 1 as disclosed in Figure 1and is thus used for opening/closing an entrance 4 of the vehicle 1. ln thefurther description of the locking arrangement 10, the entrance 4 will bereferred to as a door.

The locking arrangement 10 comprise a first manipulator 12; a secondmanipulator 14 connected to the first manipulator 12; and a locking mechanism20 mechanically connected to the first and second manipulator 12, 14. The firstmanipulator 12 may be referred to as the first door handle, and the secondmanipulator 14 may be referred to as the second door handle. The lockingarrangement 10 is configured such that rotation of the first manipulator 12and/or the second manipulator 14 about a rotation axis A, in a predetermineddirection D, deactivates the locking mechanism 20. The connection betweenthe first manipulator 12 and the second manipulator 14 comprises a play 40 inthe rotational direction D, allowing at least one of the first and the secondmanipulator 12, 14 to rotate independently of the other. By providing a relativeplay at the connection between the first manipulator 12 and the secondmanipulator 14, at least one manipulator 12, 14 can interact with the locking mechanism 20 individually.

The first manipulator 12 may comprise a first section 12” rotatable about the rotational axis A, and a second section 12”” extending essentiallyperpendicularly to the first section 12”. The second section 12”” may beconfigured as a lever or similar. However, the second section 12”” may also beconfigured as a knob or similar. The second section 12”” of the first manipulator12 may be the part of the manipulator 12 which is manually manoeuvred by a person opening or closing the door 4.

The second manipulator 14 may comprise a first section 14” rotatable aboutthe rotational axis A, and a second section 14”” extending essentiallyperpendicularly to the first section 14”. The second section 14”” may beconfigured as a lever or similar. However, the second section 14”” may also beconfigured as a knob or similar. The second section 14”” of the secondmanipulator 14 may be the part of the manipulator 14 which is manually manoeuvred by a person opening or closing the door 4.

The relative play 40 between the first and second manipulator 12, 14 is in thisembodiment formed by means of a recess 72 in the second manipulator 14.The first section 14” of the second manipulator 14 may comprise a connectionportion 70 similar to the intermediate part 30 as described in Figure 3a-b. Therecess 72 is suitably provided in the connection portion 70. The secondmanipulator 14 is however fixedly attached to the connection portion 70 andthe first manipulator 12 is rotationally attached to the connection portion 70.Thus, actuation of the second manipulator 14 will always cause the connectionportion 70 to rotate about the rotational axis A. The connection portion 70 maybe essentially cylindrical with a wall 74 and a hole 76 for the first section 12” ofthe first manipulator 12 to be inserted into. The recess 72 in the connectionportion 70 may be an opening in the wall 74 of the connection portion 70. Therecess 72 may extend along at least a part of the circumferential of the wall 74and along a part of the longitudinal extension of the connection portion 70. Thelongitudinal extension of the connection portion 70 is suitably parallel with therotational axis A of the manipulators 12, 14. The recess 72 of the connection 16 portion 70 may comprise a first end 72” and a second end 72”” in thecircumferential direction. ln this embodiment the first end 72” corresponds to afirst contact surface of the wall 74 and the second end 72”” corresponds to asecond contact surface of the wall 74.

The first section 12” of the first manipulator 12 may comprise a protrusion 50,extending essentially perpendicularly to the rotationa| axis A of the manipulator12. The protrusion 50 follows the recess 72 of the connection portion 70 in thecircumferential direction when the manipulator 12 is actuated. swï--fèïšﬁhe first manipulator 12 " 'M arranged on the outside of the door 4 and the second manipulator 14 arranged on the insideof the door 4. The first manipulator 12 may further be locked by means of aseparate lock 80 on the first manipulator 12. The separate lock 80 may be aconventional padlock. The first manipulator 12 being locked means thatactuation of the first manipulator 12 is prevented. This way, unauthorized persons are prevented from entering the vehicle 1.

The connection portion 70 is fixedly connected to a lock element 24 of thelocking mechanism 20. ln Figure 4a the first manipulator 12 and the secondmanipulator 14 are in a normal non-actuated state, in which the lock element24 is retained in a receiving element 26 of the locking mechanism 20. ln thenon-actuated state the protrusion 50 of the first manipulator 12 is adjacent orabuts the first end 72” of the recess 72. The first end 72” of the recess 72 issuitably preventing the protrusion 50 to move in the predetermined direction Dinside the recess 72. ln this embodiment, the first manipulator 12 is locked and not able to move.However, Figure 4b shows the second manipulator 14 in a fully actuated state.ln the fully actuated state, the locking mechanism 20 is deactivated and themanipulator 14 cannot be further rotated in the predetermined direction D.Since the second manipulator 14 is fixedly connected to the connection portion 17 70, actuation of the second manipulator 14 will cause the connection portion70 to rotate about the rotational axis A. Because of the play 40, the connectionportion 70 can rotate without affecting the locked first manipulator 12. Therecess 72 (the play 40) is thus so large that the second end 72” of the recess72 will not affect the protrusion 50 of the first manipulator 12 when the secondmanipulator 14 is fully actuated. The play 40 formed by the recess 72 in theconnection portion 70 suitably corresponds to an angle of rotation fordeactivating the locking mechanism 20. Thus, the play 40 allows one of themanipulators 12, 14 to rotate with an angle which deactivates the lockingmechanism 20, without rotation of the other manipulator 12, 14. The play 40may correspond to an angle of rotation within the range of 40-50 degrees.When the connection portion 70 rotates, the lock element 24 will pivot aboutthe rotational axis A and is thereby removed from the receiving element 26.The lock element 24 is suitably pivoted in an upward direction and is therebylifted out of the receiving element 26. The door 4 is thereby unlocked. Thus,even when the first manipulator 12 is prevented from being actuated by meansof a separate lock 80, the second manipulator 14 can be used to deactivatethe locking mechanism 20.
