| (54) | Lorry, load space, closure, locking system and method for closing and opening a load space |
| (57) The invention relates to a method, a system and a device for opening and closing
a closure element (11), such as a door or cover of a lorry (1) by means of which access
can be gained to a load space (3). The access means is normally in a closed state
according to the invention. The invention makes opening of the access means possible
by allowing a temporary change in the closed state of the door, for example by means
of activation by a key or a remote control (62), in which a user can perform a second
action in said state, for example pushing on the door (11), as a result of which the
door opens. Due to the fact that the state in which the door (11) can be opened is
only temporary, the door will mostly be closed, in particular locked. In addition,
the closure can be designed without a handle or other engagement means, in particular
if an ejector mechanism is used for opening the door.

[0001] The invention relates to a device for freight transport. The invention also relates to a load space provided with a closable access means. The invention also relates to a system for locking a closure element of a load space. The invention also relates to a method for opening and closing a load space.
[0002] The invention specifically relates to load spaces of transport means, such as lorries. All kinds of material can be stored in said load space. The load space may be a refrigerated cell. Such load spaces are produced by bodywork manufacturers.
[0003] A lorry having a load space with access means to said load space which can be closed and opened by means of a closure element is known. This may be a tailboard or loading platform, but may also be a door or even a sliding door. The closure means may also be a concertina door. The invention also relates to each of these closable access means. The closure element is movably connected to the load space so that the access means can be opened and closed. The door may be opened or closed by a swing mechanism or may be opened or closed by a sliding mechanism. A drive may be provided for opening and closing the door.
[0004] It is also known to lock the door in the closed state, for which purpose a key may be used. It is also known to release the lock by means of a remote control.
[0005] A problem of the present closable load spaces is that the load spaces are often opened and closed during use and that a load space is thus sometimes accessible to unauthorized individuals as locking the load space each time is time consuming.
[0006] It is an object of the invention to provide a solution for at least one of the abovementioned problems or one of the problems which is indicated in the following description.
[0007] An object is achieved by means of a device for a mobile space, in particular freight transport or a mobile freight space, such as a lorry or a trailer, but also a passenger car, which comprises a closable space, in particular a load space. The load space is preferably beam-shaped and is provided with a floor, a roof and side walls. The load space may be connected to the cabin. The load space can be closed by at least one closure element, for example a door or a flap. The load space is accessible when the closure element is in an open state. The closure element may be movably connected to the load space by means of connecting means. Due to the connecting means, the closure element can close an access opening to the load space, so that the load space has an open and a closed state. In order to lock the access opening to the load space, the load space furthermore comprises locking means for locking the closure element with respect to the access means, the locking means having a first state in which the closure element is locked when the load space is in the closed state. In the closed state, the door is closed. The locking means also has a second state. In this state, the load space can be opened. Preferably, the closure means is unlocked in this second state, so that the closure means can be opened from a closed position without additional mechanical action. The locking means can be switched between the two states, for example with a key.
[0008] It is particularly preferable to connect the locking means to a time means, for example a clock. The time means is designed to switch the locking means from the second state to the first state a predetermined time period after the locking means has been brought into the second state. This results in a locking means which switches back to the locked state in each case. When the closure element is in the closed state, it is also locked.
[0009] It is particularly advantageous to use a locking means which locks a closure means which has been closed. After the closure means has been closed, the locking means in each case assumes the first state. Effectively, the closure means locks each time it closes. According to a preferred embodiment of the invention, the closure means is automatically locked when it is closed. A user will then no longer have to go to the effort of closing the opening and protecting the goods in the load space.
[0010] Preferably, the coupling means of the door are prestressed to the closed state. This will result in the door closing each time and preferably locking each time.
[0011] It is particularly advantageous if the locking means is normally in the first state and can be switched to the second state during the maximum predetermined time period. As a result thereof, the unlocked state, in which the door can be opened from the closed state, is the maximum predetermined time period of, for example, 5 or 10 seconds. The time period is adjustable, preferably programmable, and can be modified in accordance with the wishes of the user.
[0012] The device is preferably constructed in such a manner that the closure element can only be brought from the closed state into the open state in the second state. Only when the device has been brought into the time-restricted second state can the load space be opened. In any other case, the load space remains closed. This relates to the situation on the outside. On the inside of the load space, additional opening means for the closure means may be provided.
[0013] It is particularly advantageous to design the device in such a manner that the closure element can be retained in the closed state upon switching to the second state. Thus, the load space is not opened immediately when the second state is reached, and in particular the lock is released. This makes it possible to provide a device which makes it impossible for someone outside to see whether the lock is engaged or disengaged. The closed state is thus maintained during switching to the second state. Both the first and the second state are possible in the closed state, enabling the unlocked door to be locked again.
[0014] In addition, when the predetermined period is over and the device switches back to the first state, the closure means held in the closed state will be locked and the access means to the material in the load space is closed. When the lock is disengaged, the lock will be re-engaged after a period of time. When the closure means is closed, the lock will be engaged each time. The goods in the load space are thus better protected.
[0015] In one embodiment, the closable access means to the load space is at least one access means for persons which can be closed with said closure element. This relates preferably to a side door of the load space.
[0016] According to a further embodiment, the load space comprises a movement means for moving the closure element out of the closed state and into the open state in the second state. If the second state is initiated, a further movement means can bring the closure element out of the closed state. Such a movement element can replace the known handle. Instead of a handle or another engagement means on the outside of the door/the closure element, the movement means is provided, preferably on the inside of the closure element, in order to bring the closure means out of the closed state.
[0017] Preferably, the closure means is free from engagement means on the outside of the closure means. As a result thereof, the closure means cannot be opened from the outside independently of the locked state. The door can not be opened by an unauthorized user. In combination with the temporary unlocking according to one embodiment of the invention, a more secure closure and protection of the load space is achieved. An access means without engagement means is also less easy to force open, as a thief does not have anything to hold onto.
[0018] It is furthermore advantageous if the locking means comprises the movement means. Thus, the movement means can operate depending on the state of the locking means. Preferably, the movement means only works in the second state of the locking means.
[0019] Furthermore, the movement means preferably comprises an ejector mechanism. As a result thereof, the closure element can be brought out of the closed state. The ejector mechanism may, for example, comprise a hinge. The closure element preferably comprises a catch which projects into a chamber of the locking means. The catch may be accommodated in the chamber. When the locking means is in the locked state, the catch cannot be removed from the chamber. Those skilled in the art will be familiar with the wide variety of embodiments for locking a catch of a closure element, such as a door. In the second state, preferably the unlocked state, the catch may be removable from the chamber. Preferably, an ejector mechanism, for example a mechanism connected to the chamber, used for moving the catch and the closure element out of the closed state. This may, in particular, be a hinged mechanism. The locking means and the ejector mechanism are preferably connected to an electrical power supply.
[0020] According to a further preferred embodiment, and in particular according to an embodiment for solving one or more of the problems mentioned in this description, the locking means is furthermore connected to an observation means, in which the movement means is switched on upon a predetermined observation by the observation means in the second state. As a result thereof, the closure element will be opened from the closed state in the second state, that is to say in the unlocked state, when a specific observation is made. The observation means firstly provides a two-step process for opening a closure means of a load space from a locked state. With this second step in the unlocked state, a certain observation is required in order to open the closure means. This may be a simple action, such as exerting pressure on the closure means. It may also be a certain movement which is recorded or it may also be the operation of a button. In contrast to handles which are usual on a lorry, the action to be observed is, however, not known and cannot be inferred from the outside of the load space and is thus not known to the unauthorized person. Opening the closure means, even when the closure means is unlocked and only the observation is still required in order to open the access means, is then still difficult. Opening becomes particularly difficult in combination with the time limit during which the second state is assumed.
[0021] In one preferred embodiment, the observation means is accommodated in the locking means. This may, for example, be a pressure sensor. When the locking means is unlocked and pressure is exerted on the locking means, the movement means is activated and the closure means is opened.
[0022] The device according to the invention furthermore comprises an identification means, by means of which the locking means can be switched from the first to the second state. This may be a key opening. Said identification means cooperates with a key. In one embodiment, the identification means is a receiver of a remote control. The remote control is then an electronic key.
[0023] It is preferred if the identification means comprises a programmable memory for a number of identifications, and in which the identification means is designed for comparing a received identification to identifications in the memory and in which the locking means can be switched when the comparison matches. A code in a memory and a code of an identification element, such as a key or a remote control, are thus compared. When the code of the identification element matches one of the stored codes, the movement means is activated. By using a programmable memory, it is possible to replace codes. If a remote control is lost, the old code can be erased from the memory or replaced. As a result thereof, it is readily possible to provide a locking system for a load space which can in each case be tailored to a user/driver.
[0024] The identification means, in particular the memory, is preferably arranged in the load space. As a result thereof, programming, but also operating the movement means, is only possible from inside the load space, to which only identified users have access.
[0025] It is preferred if the load space is further protected by arranging the coupling means on the inside of the load space and the closure element. As a result thereof, only a door and a door-frame are visible on the outside. An unauthorized person does not have engagement means to gain access to the load space via these access means.
[0026] The locking means is preferably also arranged on the inside of the load space. This also prevents unauthorized persons from gaining access to the locking means.
[0027] For security, the locking means is preferably provided with an operating element for switching from the first state to the second state. Thus, a user who is locked inside the load space is able to unlock and open the closure means.
[0028] The device furthermore preferably has a power supply which is connected to the locking means and the identification means. The power supply may be arranged outside the load space and be connected to the locking means by means of two electrical connections. This makes it possible to replace the power supply while the access means is closed and locked. In one embodiment, the plugs of the power supply are moulded on, as a result of which the door also works when submerged in water.
[0029] The invention also relates to a system for locking an access opening of a load space. The system comprises a locking means with a first, locked state and a second unlocked state. The locking means is designed for locking a closure element, such as a door, in the closed state. According to the invention, the locking means is connected to a time means. Said time means is designed to switch the locking means from the second state to the first state a predetermined time period after the locking means has been brought into the second state. As a result thereof, a locking system is produced which is normally in the locked state, which makes it significantly more difficult for an unauthorized user to gain access to the goods in the load space.
[0030] It is furthermore preferred if the locking means can be switched to the second state in the closed state of the closure element. As a result thereof, there is no physical change with respect to the closure element when the locking means switches. Thus, it is also possible for the unopened door to be locked again after some time. The access means can then only be opened in exceptional and controllable circumstances and is effectively locked continuously.
[0031] According to the invention, it is furthermore advantageous that the locking means comprises a movement means for bringing the closure element in the second state out of the closed state and into the open state. This may be an ejector mechanism.
[0032] It is furthermore advantageous to connect the locking means to an observation means, with a predetermined observation by the observation means in the second state switching the movement means on. This improves security further.
[0033] The locking system may be accommodated in the inside of the load space, thus making the locking system inaccessible. In particular, use is made of radio-controlled operating means for the locking system. Thus, the vital parts of the locking system can be accommodated in the load space, out of reach of any unauthorized users.
[0034] The locked and unlocked states are the states for a user on the outside of a load space. On the inside of the load space, the locking means may be provided with additional operating means for opening and unlocking the access means.
[0035] The locking system preferably works in combination with an identification means for bringing the closure means from the first state to the second state. This may be a key. A user may identify himself by means of the key or an electronic key card.
[0037] The invention also relates to a method for opening and closing a load space of a device for freight transport, such as a lorry. The method comprises providing a load space with a closure element for opening and closing the load space, locking the closure element when the load space is closed, and unlocking the closure element for opening the load space. In one embodiment, the method is characterized by the fact that unlocking according to the method lasts no longer than a predetermined time period. This results in a method in which unlocking is limited to a minimum. The method provides a system in which an access means is virtually continuously locked, resulting in improved security.
[0038] According to one embodiment, the method also comprises bringing the closure element from the closed state into the second state after a predetermined observation has been made. As a result thereof, a two-step opening of the door is achieved which increases security. In addition, an unauthorized user does not know the action which is to be observed.
[0039] According to the method, unlocking and relocking can take place in a closed state of the closure element. The door is then not opened.
[0040] The invention also relates to the use of a locking means according to one of the measures in this description in a load space, in particular for an access means to a load space.
[0041] According to another aspect, the invention can be used with a passenger vehicle. The closure element can be a door for access to the car for persons or the door by means of which access is gained to the load space of the passenger vehicle. A closure element for a passenger vehicle may be designed or operate according to any of the abovementioned measures.
[0042] According to one aspect, an object can be achieved by using the closure element and a suitable frame instead of a closed load space, for a space which is to be locked, such as a house/dwelling/building or for a household object, such as a safe or another closable and lockable means, such as a medicine cabinet. These uses are outside of the scope of protection as it is defined presently, but it should be mentioned explicitly here that these uses can be protected by possible follow-up applications (divisional applications) to the present application.
[0043] It will be clear that the measures as described above and the measures as described in connection with the description of the figures can solve several problems associated with existing prior-art closures for load spaces. For each of the solutions, a patent application may be filed, in particular in the form of a divisional application.
[0044] It will be clear to those skilled in the art that the invention can be designed in various ways. The invention will be described below by way of a non-limiting example with reference to a presently preferred embodiment illustrated by means of the drawing, in which:
Fig. 1 shows a perspective view of a first embodiment of a device according to the invention,
Fig. 2 shows a diagrammatic view of a control circuit according to one embodiment of the invention,
Fig. 3 shows an identification element associated with a system according to the invention,
Fig. 4 shows a number of steps of the method according to the invention,
Fig. 5 shows a cross section of a device according to the invention.
[0045] Fig. 1 shows a lorry 1 according to a first embodiment of a device according to the invention. The lorry 1 comprises a cabin 2 and a load space 3, in this case a beam-shaped load space with a loading floor, a roof and two vertical side walls. A rear side 6 of the load space 3 is provided with doors 7 and 8. The doors can swing open. In another embodiment, a loading platform is provided. The doors may be provided with a locking system according to the invention.
[0046] In the illustrated embodiment, the load space is separated from the cabin. The cabin may also form part of the load space. In yet another embodiment, the cabin is also a load space.
[0047] The lorry 1 comprises a frame provided with a number of wheels. The lorry may be a semitrailer. It will be clear to the person skilled in the art that various embodiments of the lorry are possible within the scope of the invention.
[0048] The side wall 5 is provided with a side door 11. The side door 11 forms a closure element for the side access of the load space 3. The side door 11 is shown in more detail in Fig. 5, which shows a cross section on line V-V, as is illustrated in Fig. 1.
[0049] Fig. 5 shows the side wall 5 on either side of the door 11. By means of a hinge 12, the door 11 can swing in the direction of arrow 13. In Fig. 5 and Fig. 1, the door is shown in the closed state. The door 11 rests against the doorpost and door seat 14 which is formed in side wall 5. The entire door seat 14 may be provided with a sealing rubber 15, which is accommodated in a groove of the peripheral edge of the door. With the invention, it is possible to provide a continuous rubber closure between the door and doorpost, as a result of which a sealing closure of the load space is achieved.
[0050] On the inside of the load space 3, the door is provided with a handle 16. A user can grasp this handle and move it, which will result in the door opening. In particular, the handle will be able to swing, as a result of which the catch 18 projecting out of housing 17 is retracted, enabling the door to be swung open in the direction of arrow 13.
[0051] Catch 18 projects from the housing 17 into a chamber which is formed in the locking means 20 according to the invention. In the closed state, the catch projects into the chamber of the locking means. The person skilled in the art will know other mechanisms for forming a closable and lockable door closure. In another embodiment, an element projects from the locking means in the door.
[0052] In this embodiment, the locking means is arranged on the inside of the load space 3 and is not directly accessible from outside. In the illustrated embodiment, the locking means is brought into a locked state.
[0053] When the door 11 is closed from the open state, the catch 18 will drop into the respective chamber of the locking means 20 and thus the door is immediately locked.
[0054] The locking means comprises an operating element 21 which is connected to a cam 23 which is pivotably accommodated in the housing 22. The operating element 21 is connected to a control circuit 24, which also includes a receiver 25. Said receiver is designed to receive an identification code from an identification element, such as a remote control 26, as is illustrated in Fig. 5. The remote control can transmit an electronic signal which can be received by the control circuit 25. If the received code matches a code by means of which access can be gained to the load space, the locking means is unlocked.
[0055] In one embodiment, unlocking does not result in any mechanical action. Unlocking can mean a different state of the locking means, but without this leading to a mechanical change. In the second state, the door may also still be locked, in particular if, according to the invention, a second step is required for opening the door.
[0056] Upon identification, the locking means is brought into the second state, in which the closure element can, if desired, be opened. In one embodiment, an inhibiting lock is released for example, so that the door can be opened. However, in the preferred embodiment, the closure means remains in the closed state, as is illustrated in Fig. 5.
[0057] In the second or unlocked state of the locking means, a time means 47 is started, for example. As soon as the second state starts, a counter is activated. After a predetermined period, for example 5 seconds, the locking means is switched back to the first state, in which the door is locked. In this embodiment, no mechanical change is required either.
[0058] Even when the door is opened in this second state, the locking means can immediately be switched back to the first state. If the door is then closed, the door will be locked immediately and cannot be opened again.
[0059] In the preferred embodiment, the door is opened from the closed state after the locking means has been brought into the second state, as a result of an observation means making a certain observation. This may be a sensor for pressure. This may be a sensor for a certain movement by a user. It may, for example, be an acidimeter which detects whether the hand of a user is pressed against a certain area, for example the area 35 indicated by dashed lines in Fig. 1. It may be a temperature gauge. It may also be a sensor for a biometric feature, such as a fingerprint or an eye scan and the like. In one embodiment, the device comprises a movement sensor, such as a camera, which observes a movement, records it and feeds it back.
[0060] When the observation means makes the predetermined observation, the door can be brought from the closed state to the open state, provided the lock has been brought to the second state. The door is opened in two stages.
[0061] In the illustrated embodiment, the user can push against the door 11 in the direction of arrow 34 from the outside. As a result thereof, the catch 18 will push against the cam 23. The pressure will be recorded, which will cause the operating element 21 to swing cam 23, thus moving the catch and thereby door 11 out of the closed position. In the illustrated embodiment, the cup plate 23 interacts with a tension member 21 as ejector mechanism. When pressure is applied to area 35, tension member 21 will cause the cup to move. As a result thereof, no handle or other engagement means is required on the outside of the door 11. The door is opened automatically from the closed position to an at least partially open position.
[0062] In one embodiment, a prestress is present, for example on the coupling means 12, in order to prestress the door to the closed position in each case. A door closer may be present which prestresses the door to the closed position.
[0063] Fig. 2 diagrammatically shows the control circuit 25. In one embodiment, a part of the control circuit is arranged on a printed circuit board, which reduces the production costs. A receiver 40 is provided with an antenna. Said receiver is tuned to receive an identification code. In another embodiment, a different frequency may be used for identification. In one embodiment, a key may be used. Preferably, an identification is used in which a code is transmitted over a distance. The control circuit is connected to a power supply, such as a battery. In one embodiment, the power supply is accommodated in the load space. As a result thereof, the power supply is not accessible from the outside and therefore protected. In one embodiment, the battery is located outside the load space so that the battery can be disconnected and thus release the lock, for example in case of emergency or if the identification is lost.
[0064] The receiver 40 is connected to bus 42. The bus provides the communication in the control circuit 25. Signals can be transmitted via the bus between the various control circuit means of the control circuit, as illustrated in the embodiment in Fig. 2.
[0065] The received code can be transmitted to a processor 44 where it is compared with codes which are stored in a memory 45. This may be a buffer memory, in particular a shift memory. The memory is designed to store a number of codes, in particular 5 or 8 or more codes.
[0066] The memory 45 may be programmable. The control circuit may be provided with an input, by means of which an identification code can be programmed into the memory. As a result thereof, it is possible to replace the old code by a new code associated with a new identification element if an identification element is lost.
[0067] In one embodiment, an input means is provided on the outside of the load space. The user can then input an identification code via the input means, which can be compared to a code stored in memory 45.
[0068] The processor is able to carry out a comparison. When a received code matches a stored code, the control circuit can bring the locking means into a second state. Sensor connection 46 may be connected to an observation means according to the invention. If a signal is received via connection 46, indicating that the predetermined observation has been made, and processor 44 has ascertained that the identification is correct, a signal can be transmitted via an output 47 to open the access means. The lock can then be unlocked and in a preferred embodiment a movement means can be instructed to bring the door 11 from the closed position to the open state. The door can then be opened further by the user. The movement means may comprise an ejector mechanism. A catch pushes the door open.
[0069] In one embodiment, a buzzer 48 is present and connected to the bus. In one embodiment, an audible signal is emitted in the second state, so that the user knows that the door has been brought into the second state.
[0070] Time means 49 is connected to the bus 42. The time means 49 is designed to indicate a fixed period. If, for example, the second state is assumed as a result of a positive identification, the time means 49 can be started. When the time means reaches its predetermined time limit, the second state can be returned to the first state. In this embodiment, the buzzer is then switched off. When the time period is over, the lock is locked again. If the observation is subsequently made, the door is established now not opened, as it is locked.
[0071] Fig. 3 shows an exemplary identification element 26. This element is useful and can be carried by the user. It can be incorporated into other portable devices. In one embodiment, an identification means is used which is incorporated in the mobile telephone of a user. This may, for example, be achieved by means of a Bluetooth application. The mobile telephone can transmit an identification code. Reception of this code by the lock according to the invention will then lead to a switch from the first to the second state according to the invention.
[0072] In the illustrated embodiment according to Fig. 3, the identification element 26 comprises a button 51. Upon operation thereof by the user, a code is retrieved from a memory 52 and transmitted via a transmitter 53, for example using radio frequencies.
[0073] Fig. 4 shows the most important steps of a method according to the invention. According to one embodiment, the load space of a lorry is in a closed state 60. The closure element according to the invention closes the access means for the load space. The closure means is preferably locked in this closed state. In the closed state and first state of the locking means according to the invention, opening from outside will only be possible according to the method illustrated in Fig. 4.
[0074] If an identification code 61 is received from an identification element 62, the locking means will be switched to a next, second state 63. In this second state, an observation can be made. The closure means preferably still remains closed.
[0075] When a predetermined action 64 is observed, the closure element will be opened. The predetermined action 64 may, for example, be carried out by the hand of a user.
[0076] When this action is observed, switching to a state 65 is effected, in which the door is opened. The user has access to the load space.
[0077] The lock can be switched back to the first, locked state. In this first state, switching from state 63 to state 65 cannot be carried out again. In state 63, the user is only allowed a limited amount of time to carry out the action. A time means will ensure that the system according to the invention is returned to the original state at the end of a predetermined period of time, as is indicated by arrow 67.
[0078] Whenever the door is closed, it will be locked each time, thus saving the user time. He no longer has to carry out additional actions in order to lock the door and leave the load space unattended.
[0079] An access means for a load space according to the invention can be produced without the customary engagement means. In particular, according to the invention, a handle for acting on the door of the access means can be omitted. This acts as a deterrent to any individuals who may want to gain unauthorized access to the load space.
