Definitions

  • a locking arrangement and a vehicle comprising such a locking
  • the present invention relates to a locking arrangement for an entrance of a vehicle and a vehicle comprising such a locking arrangement. More specifically the present invention relates to a locking arrangement for a ballistic vehicle cab, allowing movement of manipulators independently of each other.
  • Ballistic vehicle cabs typically comprise very sturdy locking arrangements on the doors in order to withstand the forces that the cab may be exposed to.
  • a locking arrangement for a vehicle typically comprises an inside door handle and an outside door handle connected to each other.
  • the locking arrangement also comprises a locking mechanism which may be electronically connected to the door handles. By actuating/rotating any of the door handles, the locking mechanism may be deactivated and the door can be opened.
  • the locking arrangements are used to keep the doors shut during operation of the vehicle and when the vehicle is parked.
  • the locking arrangement may be configured differently depending on the desired functionality of the locking arrangement. It may 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 is electrically operable and has an additional mechanical transmission for emergency opening in case of failure of electric current supply or similar.
  • Document US61 12564 A discloses a lock for motor vehicle doors allowing the lock and thus the door to be actuated or opened by each door handle. The lock also allows a child-proof state where actuation of the outside door handle can open the door but the inside door handle cannot.
  • An object of the present invention is thus to achieve an advantageous locking arrangement, which enables deactivation of the locking mechanism and thus opening of the entrance from the inside at all times.
  • Another object of the invention is to achieve an advantageous locking arrangement for an entrance of a vehicle, which locking arrangement increases safety.
  • the herein mentioned objects are achieved by a locking arrangement for an entrance of a vehicle and a vehicle comprising such an arrangement according to the independent claims.
  • a locking arrangement for an entrance of a vehicle comprising: a first manipulator; a second manipulator connectable to the first manipulator; and a locking mechanism mechanically connectable to the first and second manipulator, wherein the locking arrangement is configured such that rotation of the first manipulator and/or the second manipulator about a rotation axis, in a predetermined direction, deactivates the locking mechanism, wherein the connection between the first manipulator and the second manipulator comprises a play in the rotational direction, allowing at least one of the first and second manipulator to rotate independently of the other manipulator.
  • the connection between the first manipulator and the second manipulator may be referred to as an interface, wherein the interface comprises a play in the rotational direction, allowing at least one of the first and second manipulator to rotate independently of the other manipulator.
  • the entrance associated with the locking arrangement may be a door, a window, a hatch or similar, for getting access to the inside of a vehicle.
  • the term“door” will be used herein but it is to be understood that this is only an example of an object that can be equipped with the locking arrangement.
  • the first manipulator may be referred to as a first door handle and the second manipulator may be referred to as a second door handle.
  • the first manipulator may comprise a first section rotatable about the rotational axis and the second manipulator may comprise a first section rotatable about the rotational axis.
  • the manipulators are suitably adapted to be arranged, such that the first sections of the manipulators are aligned. The first manipulator and the second manipulator thereby have a common rotational axis when being connected.
  • the locking arrangement is configured such that when the first manipulator and the second manipulator each are in a normal non-actuated state, the locking mechanism is activated. The door is thereby retained in a closed position.
  • the locking mechanism When the first manipulator or the second manipulator is actuated and thus rotated in the predetermined direction, the locking mechanism will be mechanically affected and at a predetermined angle of rotation of the manipulator, the locking mechanism is deactivated and the door is openable.
  • connection between the first manipulator and the second manipulator comprises a play in the rotational direction, allowing both the first and the second manipulator to rotate independently of each other.
  • both manipulators can interact with the locking mechanism individually and the locking mechanism may thereby be deactivated by means of one of the manipulators, without actuation/rotation of the other manipulator.
  • the first manipulator may be adapted to be arranged on the outside of the door and the second manipulator may be adapted to be arranged on the inside of the door.
  • the first manipulator may further be lockable by means of attaching a separate lock to the first manipulator.
  • the first manipulator may for example be lockable by means of a padlock.
  • the first manipulator being lockable means that actuation of the first manipulator can be prevented by means of a separate lock.
  • the second manipulator can be actuated to deactivate the locking mechanism even when the first manipulator is locked and physically prevented from being actuated. This way, a simple and reliable locking arrangement is achieved, which increases safety.
  • the locking mechanism may comprise multiple components, such as rotary latches, locking wedges, gear wheels or similar.
  • the configuration of the locking mechanism is not per se relevant for the function of the invention as long as it is mechanically connected to the first manipulator and the second manipulator according to the herein explained embodiments.
  • the play at the connection between the first manipulator and the second manipulator corresponds to an angle of rotation for deactivating the locking mechanism.
  • the play is configured to allow at least one of the manipulators to rotate with an angle which deactivates the locking mechanism, without rotation of the other manipulator.
  • the angle of rotation for deactivating the locking mechanism depends on the configuration of the locking mechanism and the connection between the locking mechanism and the manipulators.
  • the play may correspond to an angle of rotation within the range of 40-50 degrees.
  • the play may correspond to an angle of rotation of 45 degrees.
  • the locking arrangement further comprises an intermediate part for connecting the first manipulator and the second manipulator, wherein the relative play between the first and second manipulator is formed by means of a recess in the intermediate part.

  • the play may be achieved by a recess or groove in the cylinder wall of the intermediate part.
  • the recess in the intermediate part may extend along at least a part of the circumferential of the cylinder wall.
  • the recess of the intermediate part may thus have a first end and a second end in the circumferential direction.

  • the recess in the intermediate part may be an opening in the cylinder wall.
  • the intermediate part may have a cross-section which is essentially C-shaped.
  • the first manipulator and the second manipulator are rotationally attached to the intermediate part.

  • the first sections of the first manipulator and the second manipulator respectively may each comprise a protrusion, extending essentially perpendicularly to the rotational axis of the manipulators.
  • the protrusions are adapted to be guided in the rotational direction in the recess of the intermediate part.
  • the protrusions are thus adapted to follow the recess in the circumferential direction when the manipulators are actuated. Rotating the manipulators, such that the protrusions move between the first and the second end of the recess will not affect the intermediate part.
  • the intermediate part may be mechanically connected to the locking mechanism.
  • the intermediate part may comprise outer teeth or grooves adapted to engage with corresponding teeth or protrusions of a rack of the locking mechanism.
  • the rack is suitably connected to a lock bolt which in a retracted state unlocks the door and in an extended state locks the door.
  • the intermediate part may be fixedly connected to a lock element of the locking mechanism.
  • the intermediate part When the manipulators are in the non-actuated state the intermediate part is suitably positioned such that the lock element is retained in a receiving element whereby the door is locked.
  • the lock element When any of the manipulators are actuated and the intermediate part is rotated in the predetermined direction, the lock element is pivoted about the rotational axis and is thereby removed from the receiving element. The door is thereby openable.
  • the relative play between the first and second manipulator is formed by means of a recess in the second manipulator.
  • the first section of the second manipulator may comprise a connection portion similar to the intermediate part as described above.
  • connection portion may thus be adapted to be mechanically connected to the locking mechanism in the same way as the intermediate part.

  • the connection portion will rotate and the protrusion of the first manipulator will no longer abut the first end of the recess.
  • the second manipulator can thus be actuated and deactivate the locking mechanism independently of the first manipulator.

Description

A locking arrangement and a vehicle comprising such a locking
arrangement
TECHNICAL FIELD
The present invention relates to a locking arrangement for an entrance of a vehicle and a vehicle comprising such a locking arrangement. More specifically the present invention relates to a locking arrangement for a ballistic vehicle cab, allowing movement of manipulators independently of each other.
BACKGROUND
Ballistic vehicle cabs typically comprise very sturdy locking arrangements on the doors in order to withstand the forces that the cab may be exposed to. A locking arrangement for a vehicle typically comprises an inside door handle and an outside door handle connected to each other. The locking arrangement also comprises a locking mechanism which may be electronically connected to the door handles. By actuating/rotating any of the door handles, the locking mechanism may be deactivated and the door can be opened. The locking arrangements are used to keep the doors shut during operation of the vehicle and when the vehicle is parked. The locking arrangement may be configured differently depending on the desired functionality of the locking arrangement. It may 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 is electrically operable and has an additional mechanical transmission for emergency opening in case of failure of electric current supply or similar. Document US61 12564 A discloses a lock for motor vehicle doors allowing the lock and thus the door to be actuated or opened by each door handle. The lock also allows a child-proof state where actuation of the outside door handle can open 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 locking arrangement for an entrance of a vehicle, which alleviates or at least reduces drawbacks with prior art.
An object of the present invention is thus to achieve an advantageous locking arrangement, which enables deactivation of the locking mechanism and thus opening of the entrance from the inside at all times.
Another object of the invention is to achieve an advantageous locking arrangement for an entrance of a vehicle, which locking arrangement increases safety. The herein mentioned objects are achieved by a locking arrangement for an entrance of a vehicle and a vehicle comprising such an arrangement according to the independent claims.
Hence, according to an aspect of the present invention a locking arrangement for an entrance of a vehicle is provided, the locking arrangement comprising: a first manipulator; a second manipulator connectable to the first manipulator; and a locking mechanism mechanically connectable to the first and second manipulator, wherein the locking arrangement is configured such that rotation of the first manipulator and/or the second manipulator about a rotation axis, in a predetermined direction, deactivates the locking mechanism, wherein the connection between the first manipulator and the second manipulator comprises a play in the rotational direction, allowing at least one of the first and second manipulator to rotate independently of the other manipulator. The connection between the first manipulator and the second manipulator may be referred to as an interface, wherein the interface comprises a play in the rotational direction, allowing at least one of the first and second manipulator to rotate independently of the other manipulator. The entrance associated with the locking arrangement may be a door, a window, a hatch or similar, for getting access to the inside of a vehicle. For the sake of describing the locking arrangement the term“door” will be used herein but it is to be understood that this is only an example of an object that can be equipped with the locking arrangement.
The first manipulator may be referred to as a first door handle and the second manipulator may be referred to as a second door handle. The first manipulator may comprise a first section rotatable about the rotational axis and the second manipulator may comprise a first section rotatable about the rotational axis. The manipulators are suitably adapted to be arranged, such that the first sections of the manipulators are aligned. The first manipulator and the second manipulator thereby have a common rotational axis when being connected.
Suitably, the locking arrangement is configured such that when the first manipulator and the second manipulator each are in a normal non-actuated state, the locking mechanism is activated. The door is thereby retained in a closed position. When the first manipulator or the second manipulator is actuated and thus rotated in the predetermined direction, the locking mechanism will be mechanically affected and at a predetermined angle of rotation of the manipulator, the locking mechanism is deactivated and the door is openable. By providing a relative play at the connection between the first manipulator and the second manipulator, such that at least one of the manipulators can rotate independently of the other, at least one manipulator can interact with the locking mechanism individually.
According to an example the connection between the first manipulator and the second manipulator comprises a play in the rotational direction, allowing both the first and the second manipulator to rotate independently of each other. This way, both manipulators can interact with the locking mechanism individually and the locking mechanism may thereby be deactivated by means of one of the manipulators, without actuation/rotation of the other manipulator.
The first manipulator may be adapted to be arranged on the outside of the door and the second manipulator may be adapted to be arranged on the inside of the door. The first manipulator may further be lockable by means of attaching a separate lock to the first manipulator. The first manipulator may for example be lockable by means of a padlock. The first manipulator being lockable means that actuation of the first manipulator can be prevented by means of a separate lock. In some situations it may be desirable to be able to prevent rotation of one of the manipulators and thus prevent opening of the door by means of one of the manipulators. For example, it may be desirable to prevent unauthorized persons to enter the vehicle whereby the manipulator on the 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 by means of the other manipulator from the inside of the vehicle. By providing a relative play at the connection between the first manipulator and the second manipulator, such that at least one of the manipulators can rotate independently of the other, the second manipulator can be actuated to deactivate the locking mechanism even when the first manipulator is locked and physically prevented from being actuated. This way, a simple and reliable locking arrangement is achieved, which increases safety.
The locking mechanism may comprise multiple components, such as rotary latches, locking wedges, gear wheels or similar. The configuration of the locking mechanism is not per se relevant for the function of the invention as long as it is mechanically connected to the first manipulator and the second manipulator according to the herein explained embodiments.
According to an embodiment the play at the connection between the first manipulator and the second manipulator corresponds to an angle of rotation for deactivating the locking mechanism. Thus, the play is configured to allow at least one of the manipulators to rotate with an angle which deactivates the locking mechanism, without rotation of the other manipulator. The angle of rotation for deactivating the locking mechanism depends on the configuration of the locking mechanism and the connection between the locking mechanism and the manipulators. The play may correspond to an angle of rotation within the 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 an intermediate part for connecting the first manipulator and the second manipulator, wherein the relative play between the first and second manipulator is formed by means of a recess in the intermediate part. The intermediate part may thus constitute an interface between the first and the second manipulator. The first manipulator and the second manipulator may thus be connected via the intermediate part. The intermediate part may be essentially cylindrical with a cylinder wall and a through hole. The first section of the first manipulator and the first section of the second manipulator may be adapted to be inserted into the through hole of the intermediate part from opposite directions. The intermediate part and the first sections of the manipulators are thus adapted to be coaxially arranged. When any of the manipulators is actuated the first section of the manipulator is rotated about the rotational axis and will rotate the intermediate part in the same rotational direction. The intermediate part is adapted to be mechanically connected to the locking mechanism, such that rotation of the intermediate part in the predetermined direction deactivates the locking mechanism. The play may be achieved by a recess or groove in the cylinder wall of the intermediate part. To achieve the play and thereby allow the first sections of the manipulators to rotate independently of each other, the recess in the intermediate part may extend along at least a part of the circumferential of the cylinder wall. The recess 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 longitudinal direction of the intermediate part. The recess in the intermediate part may be an opening in the cylinder wall. Thus, the intermediate part may have a cross-section which is essentially C-shaped.
According to an embodiment the first manipulator and the second manipulator are rotationally attached to the intermediate part. Thus both manipulators can be actuated individually to deactivate the locking mechanism without affecting the other manipulator. The first sections of the first manipulator and the second manipulator respectively may each comprise a protrusion, extending essentially perpendicularly to the rotational axis of the manipulators. The protrusions are adapted to be guided in the rotational direction in the recess of the intermediate part. The protrusions are thus adapted to follow the recess in the circumferential direction when the manipulators are actuated. Rotating the manipulators, such that the protrusions move between the first and the second end of the recess will not affect the intermediate part. However, when a manipulator is in a position where the protrusion has reached and abuts the first or the second end of the recess, rotation of the manipulator in direction of the 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 abutting the first end of the recess. The first end of the recess may thereby prevent the protrusion to move further in the predetermined direction inside the recess. Thus, when any of the manipulators is actuated and rotated in the predetermined direction, the intermediate part will be rotated by the protrusion of the actuated manipulator abutting the cylinder wall. Because of the recess (play) in the intermediate part, when one manipulator is rotating the intermediate part, the protrusion of the other manipulator will no longer abut the 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 the recess abuts the protrusion of the other manipulator, the intermediate part will rotate the other manipulator. The intermediate part may be mechanically connected to the locking mechanism. The intermediate part may comprise outer teeth or grooves adapted to engage with corresponding teeth or protrusions of a rack of the locking mechanism. The rack is suitably connected to a lock bolt which in a retracted state unlocks the door and in an extended state locks the door. Alternatively, the intermediate part may be fixedly connected to a lock element of the locking mechanism. When the manipulators are in the non-actuated state the intermediate part is suitably positioned such that the lock element is retained in a receiving element whereby the door is locked. When any of the manipulators are actuated and the intermediate part is rotated in the predetermined direction, the lock element is pivoted about the rotational axis and is thereby removed from the receiving element. The door is thereby openable. According to an embodiment the relative play between the first and second manipulator is formed by means of a recess in the second manipulator. The first section of the second manipulator may comprise a connection portion similar to the intermediate part as described above. The connection portion may thus be adapted to be mechanically connected to the locking mechanism in the same way as the intermediate part. However, in this embodiment the second manipulator is fixedly attached to the connection portion and the first manipulator is rotationally attached to the connection portion. Thus, the connection portion may be essentially cylindrical with a wall and a hole for the first section of the first manipulator to be inserted into. The play may be achieved by a recess in the wall of the connection portion. The recess in the connection portion may extend in a first direction along at least a part of the circumferential of the wall. The recess of the connection portion 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 a part of the longitudinal direction of the connection portion. The recess in the intermediate part may be an opening in the wall. The first section of the first manipulator may comprise a protrusion, extending essentially perpendicularly to the rotational axis of the manipulator. The protrusion is adapted to be guided in the rotational direction in the recess of the connection portion. Suitably, when the first and second manipulators are in a non-actuated state, the protrusion of the first manipulator is adjacent or abuts the first end of the recess. The first end of the recess is suitably preventing the protrusion to move further in the predetermined direction inside the recess. Thus, when the first manipulator is actuated and rotated in the predetermined direction, the connection portion and thus the second manipulator will be rotated by the protrusion of the first manipulator. However, because of the recess (play) in the connection portion, if only the second manipulator is actuated the connection portion will rotate and the protrusion 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 be actuated and deactivate the locking mechanism independently of the first manipulator. This way, even when the first manipulator is prevented from being actuated by means of a separate lock, the second manipulator can be used to deactivate the locking mechanism.
A vehicle comprising the herein described locking arrangement is also provided. The vehicle may comprise a ballistic cab comprising the locking arrangement. Ballistic vehicle cabs typically comprise very sturdy locking arrangements on the doors in order to withstand the forces that the cab may be exposed to. The locking arrangement according to the invention is a mechanically simple and durable construction which is suitable for ballistic vehicle cabs.
Further objects, advantages and novel features of the present invention will become apparent to one skilled in the art from the following details, and also by putting the invention into practice. Whereas the invention is described below, it should be noted that it is not restricted to the specific details described. Specialists having access to the teachings herein will recognise further applications, modifications and incorporations within other fields, which are within the scope of the invention. BRIEF DESCRIPTION OF THE DRAWINGS
For fuller understanding of the present invention and further objects and advantages of it, the detailed description set out below should be read together with the accompanying drawings, in which the same reference notations denote similar items in the various drawings, and in which:

embodiment of the invention;

DETAILED DESCRIPTION OF THE DRAWINGS Figure 1 schematically shows a side view of a vehicle 1 according to an embodiment of the invention. The vehicle 1 comprises a vehicle cab 2 for an operator of the vehicle 1. The vehicle cab 2 comprises an entrance 4. The vehicle 1 further comprises at least one locking arrangement 10 for the vehicle entrance 4. The entrance 4 may be a door, a hatchet or a window. The locking arrangement 10 will be further described in Figure 2-4. The vehicle 1 may be a heavy vehicle, e.g. a truck or a bus. The vehicle 1 may alternatively be a passenger car. The vehicle may be a hybrid vehicle comprising an electric machine (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 4 of 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 1 and is thus used for opening/closing an entrance 4 of the vehicle 1. In the further description of the locking arrangement 10, the entrance 4 will be referred to as a door.
The locking arrangement 10 comprise a first manipulator 12; a second manipulator 14 connectable to the first manipulator 12; and a locking mechanism 20 mechanically connectable to the first and second manipulator 12, 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 locking arrangement 10 is configured such that rotation of the first manipulator 12 and/or the second manipulator 14 about a rotation axis A, in a predetermined direction D, deactivates the locking mechanism 20. The connection between the first manipulator 12 and the second manipulator 14 comprises a play 40 in the rotational direction, allowing both the first and the second manipulator 12, 14 to rotate independently of each other. By providing a relative play at the connection between the first manipulator 12 and the second manipulator 14, such that they can rotate independently of the other, both manipulators 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 essentially perpendicularly to the first section 12’. At least a part of the first section 12’ is adapted to be arranged inside the vehicle door 4. The second section 12” may be configured as a lever or similar. However, the second section 12” may also be configured as a knob or similar. The second section 12” of the first manipulator 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 about the rotational axis A, and a second section 14” extending essentially perpendicularly to the first section 14’. At least a part of the first section 14’ is adapted to be arranged inside the vehicle door 4. The second section 14” may be configured as a lever or similar. However, the second section 14” may also be configured as a knob or similar. The second section 14” of the second manipulator 14 may be the part of the manipulator 14 which is manually manoeuvred by a person opening or closing the door 4.
The locking arrangement 10 further comprises an intermediate part 30 for connecting the first manipulator 12 and the second manipulator 14. The intermediate part 30 may comprise a recess 32 forming the relative play 40 between the first and second manipulator 12, 14. In this embodiment the intermediate part 30 is essentially cylindrical with a cylinder wall 36 and a through hole 38. The first section 12’ of the first manipulator 12 and the first section 14’ of the second manipulator 14 may be inserted into the through hole 38 of the intermediate part 30 from opposite directions. The first and the second manipulators 12, 14 are suitably arranged, such that the first sections 12’, 14’ of the manipulators 12, 14 are aligned. The first manipulator 12 and the second manipulator 14 thereby have a common rotational axis A. The intermediate part 30 is suitably mechanically connected to the locking mechanism 20, such that rotation of the intermediate part 30 about the rotational axis A, in the predetermined direction D, deactivates the locking mechanism 20. The locking mechanism 20 may comprise multiple components, such as rotary latches, locking wedges, gear wheels or similar. For the sake of clarity only the part of the locking mechanism 20 being mechanically connected with the manipulators 12, 14 is shown. In this embodiment the intermediate part 30 comprises outer teeth or grooves adapted to engage with corresponding teeth or protrusions of a rack 22 of the locking mechanism 20. When the intermediate part 30 rotates, the engagement of teeth will move the rack 22 linearly. The rack 22 is suitably connected to a lock bolt (not shown) which is in a retracted or extended state depending on the position of the rack 22. In the retracted state the door 4 is unlocked and in the extended state the door 4 is locked. The recess 32 in the intermediate part 30 may be an opening in the cylinder wall 36, the opening extending along a part of the circumferential of the cylinder wall 36 and along at least a part of the longitudinal extension of the intermediate part 30. The longitudinal extension of the intermediate part 30 is suitably parallel with the rotational axis A. The recess 32 of the intermediate part 30 may comprise a first end 32’ and a second end 32” in the circumferential direction. In this embodiment the first end 32’ corresponds to a first 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 the second manipulator 14 may each comprise a protrusion 50, 52, extending essentially 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 the intermediate part 30 in the circumferential direction when the manipulators 12, 14 are actuated. The first end 32’ of the recess 32 is suitably preventing the protrusions 50, 52 to move further in the predetermined direction D inside the recess 32. The first end 32’ may thus limit the recess 32 in the predetermined direction D.
Figure 2a shows the first manipulator 12 and the second manipulator 14 in a normal non-actuated state, in which the locking mechanism 20 is activated. In the non-actuated state the protrusions 50, 52 of the manipulators 12, 14 are adjacent or abut the first end 32’ of the recess 32. Rotation of any of the manipulators 12, 14 in the predetermined direction D will thereby essentially immediately cause the intermediate part 30 to rotate together with the manipulator 12, 14.
Figure 2b shows the first manipulator 12 in a fully actuated state. In the fully actuated state, the locking mechanism 20 is deactivated and the manipulator 12 cannot be further rotated in the predetermined direction D. By actuating the first manipulator 12, the protrusion 50 of the first manipulator 12 will apply a force on the first end 32’ of the recess 32 which rotates the intermediate part 30. When the intermediate part 30 rotates, the first end 32’ of the recess 32 will move away from the protrusion 52 of the second manipulator 14 and because of the play 40, the second manipulator 14 will remain still. The recess 32 (the play 40) is thus so large that the second end 32” of the recess 32 will not affect the protrusion 52 of the second manipulator 14 when the first manipulator 12 is fully actuated. The play 40 formed by the recess 32 in the intermediate part 30 suitably corresponds to an angle of rotation for deactivating the locking mechanism 20. Thus, the play 40 allows one of the manipulators 12, 14 to rotate with an angle which deactivates the locking mechanism 20, without rotation of the other manipulator 12, 14. The play 40 may correspond to an angle of rotation within the range of 40-50 degrees.
Only actuation of the first manipulator is illustrated in Figure 2b but it is to be understood that the locking arrangement 10 would function the same way irrespectively of the manipulator 12, 14 being actuated. Figures 3a-b schematically illustrate a locking arrangement 10 for an entrance 4 of a vehicle 1 according to an embodiment of the invention. The locking arrangement 10 is suitably configured as disclosed with regard to Figure 2a and Figure 2b, with the difference that the intermediate part 30 is fixedly connected to a lock element 24 of the locking mechanism 20. In Figure 3a the first 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 element 26 of the locking mechanism 20. In this state the locking mechanism 20 is activated and the door 4 is thus locked. In the non-actuated state the protrusions 50, 52 of the manipulators 12, 14 are adjacent or abut the first end 32’ of the recess 32. Rotation of any of the manipulators 12, 14 in the predetermined direction D will thereby cause the intermediate part 30 to rotate together with the manipulator 12, 14. Figure 3b shows the first manipulator 12 in a fully actuated state. In the fully actuated state, the locking mechanism 20 is deactivated and the manipulator 12 cannot be further rotated in the predetermined direction D. By actuating the first manipulator 12, the protrusion 50 of the first manipulator 12 will apply a force on the first end 32’ of the recess 32 which rotates the intermediate part 30. When the intermediate part 30 rotates, the lock element 24 pivots about the 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 4 of 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 1 and is thus used for opening/closing an entrance 4 of the vehicle 1. In the further description of the locking arrangement 10, the entrance 4 will be referred to as a door.
The locking arrangement 10 comprise a first manipulator 12; a second manipulator 14 connected to the first manipulator 12; and a locking mechanism 20 mechanically connected to the first and second manipulator 12, 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 locking arrangement 10 is configured such that rotation of the first manipulator 12 and/or the second manipulator 14 about a rotation axis A, in a predetermined direction D, deactivates the locking mechanism 20. The connection between the first manipulator 12 and the second manipulator 14 comprises a play 40 in the rotational direction D, allowing at least one of the first and the second manipulator 12, 14 to rotate independently of the other. By providing a relative play at the connection between the first manipulator 12 and the second manipulator 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 essentially perpendicularly to the first section 12’. The second section 12” may be configured as a lever or similar. However, the second section 12” may also be configured as a knob or similar. The second section 12” of the first manipulator 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 about the rotational axis A, and a second section 14” extending essentially perpendicularly to the first section 14’. The second section 14” may be configured as a lever or similar. However, the second section 14” may also be configured as a knob or similar. The second section 14” of the second manipulator 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 this embodiment formed by means of a recess 72 in the second manipulator 14. The first section 14’ of the second manipulator 14 may comprise a connection portion 70 similar to the intermediate part 30 as described in Figure 3a-b. The recess 72 is suitably provided in the connection portion 70. The second manipulator 14 is however fixedly attached to the connection portion 70 and the first manipulator 12 is rotationally attached to the connection portion 70. Thus, actuation of the second manipulator 14 will always cause the connection portion 70 to rotate about the rotational axis A. The connection portion 70 may be essentially cylindrical with a wall 74 and a hole 76 for the first section 12’ of the first manipulator 12 to be inserted into. The recess 72 in the connection portion 70 may be an opening in the wall 74 of the connection portion 70. The recess 72 may extend along at least a part of the circumferential of the wall 74 and along a part of the longitudinal extension of the connection portion 70. The longitudinal extension of the connection portion 70 is suitably parallel with the rotational axis A of the manipulators 12, 14. The recess 72 of the connection portion 70 may comprise a first end 72’ and a second end IT in the circumferential direction. In this embodiment the first end 72’ corresponds to a first contact surface of the wall 74 and the second end 72” corresponds to a second 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 rotational axis A of the manipulator 12. The protrusion 50 follows the recess 72 of the connection portion 70 in the circumferential direction when the manipulator 12 is actuated.
In this embodiment the first manipulator 12 may be arranged on the outside of the door 4 and the second manipulator 14 may be arranged on the inside of the door 4. The first manipulator 12 may further be locked by means of a separate lock 80 on the first manipulator 12. The separate lock 80 may be a conventional padlock. The first manipulator 12 being locked means that actuation 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 the locking mechanism 20. In Figure 4a the first 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 element 26 of the locking mechanism 20. In the non-actuated state the protrusion 50 of the first manipulator 12 is adjacent or abuts the first end 72’ of the recess 72. The first end 72’ of the recess 72 is suitably preventing the protrusion 50 to move in the predetermined direction D inside the recess 72.
In 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. In the fully actuated state, the locking mechanism 20 is deactivated and the manipulator 14 cannot be further rotated in the predetermined direction D. Since the second manipulator 14 is fixedly connected to the connection portion 70, actuation of the second manipulator 14 will cause the connection portion 70 to rotate about the rotational axis A. Because of the play 40, the connection portion 70 can rotate without affecting the locked first manipulator 12. The recess 72 (the play 40) is thus so large that the second end 72” of the recess 72 will not affect the protrusion 50 of the first manipulator 12 when the second manipulator 14 is fully actuated. The play 40 formed by the recess 72 in the connection portion 70 suitably corresponds to an angle of rotation for deactivating the locking mechanism 20. Thus, the play 40 allows one of the manipulators 12, 14 to rotate with an angle which deactivates the locking mechanism 20, without rotation of the other manipulator 12, 14. The play 40 may 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 about the 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 thereby lifted 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 means of a separate lock 80, the second manipulator 14 can be used to deactivate the locking mechanism 20. The foregoing description of the preferred embodiments of the present invention is provided for illustrative and descriptive purposes. It is not intended to be exhaustive or to restrict the invention to the variants described. Many modifications and variations will obviously be apparent to one skilled in the art. The embodiments have been chosen and described in order best to explain the principles of the invention and its practical applications and hence make it possible for specialists to understand the invention for various embodiments and with the various modifications appropriate to the intended use.
