    LOCKING DEVICE/BED STRIKER, PRIMARILY INTENDED FOR SECURING ABED IN A VEHICLE TECHNICAL FIELD The present invention relates to a locking device and a method for providing a locking device, a bed striker, that has acrash load absorber function for keeping the device lockedalso when subjected to high loads/stresses. The invention isprimarily intended for keeping a vehicle bed locked during acollision, exerting high stresses on the components in thevehicle and in the locking device. The invention particularlyrelates to locking devices for use in heavy commercial/-industrial vehicles but could of course be used in other typesof vehicles or for other purposes. The invention as wellrelates to and covers a vehicle provided with a locking device according to the invention.
    BACKGROUND ART On the market there are a large variety of heavy commercial/- industrial vehicles. In vehicles, like trucks, intended for long-distance transportation, are often at least one bedinstalled in the cab to allow the driver to rest during thedrive.
    If the vehicle is equipped with two beds, they are usually located one above the other, a lower and an upper bed,one intended for the driver and the other intended for apassenger or a co-driver. foldable, At least the upper bed will beagainst the rear wall of the cabin. As the space ina vehicle cabin is relatively limited the space below the lower bed is normally used for storage, food/drinks, of e.g. storage of tools, personal items, etc. Access to this space is usually done from above of practical reasons, and thismeans that the lower bed and its mattress also have to be foldable.
    A bed and its mattress is a relatively large and heavycomponent in a vehicle and it is important that the bed staysin place in the event of a traffic accident. As the bed isfoldable it is only mounted in the rear long side of itsframe, normally onto the rear cabin wall, by means of a coupleof hinges. When folded out to its horizontal use position itis often locked in place by two bed strikers installed belowor at the sides of the bed and its framework.If the vehicle is subjected to a traffic accident it isimportant that the bed does not come loose. When a bed lockfails to hold the bed closed the stored objects under the bedmay come loose in the cabin and such objects may seriouslyinjure the driver and the passenger. As the bed itself mayweigh about 30-40 kg it might also be harmful for a driver or a passenger if it unlocks and come loose during a crash.
    Most designs of such bed locks are consisting of a simple bentsteel pin/wire. Such a component will not safely secure thatthe bed stays in place and is securely locked when the vehicleis subjected to a deceleration in excess of a predetermined threshold. Normally the locking pin will deform due to suddenand uneven load and eventually break due to high exhaustion insome part of the locking device. With higher demands on crashperformance, collision forces gets higher and higher which inturn demands locking components that are able to withstand a very high load without breaking or failing.
    This could of course be solved by designing the locking component larger/stiffer. But a too stiff locking device may still break and the locking function of the bed can fail when a really high crash load occurs.
    Many attempts have been made to provide a simple and sustainable solution to the problems mentioned.
    US2010314890 illustrates an example of a powered strikermechanism for engaging a door latch, mounted to a supportstructure in a vehicle and for engagement with a latchmechanism, like a worm gear, to close a door. The inventionconcerns latches that require a great force to fully close thedoor from a primary latch position into the fully closedposition, and especially sliding doors for vans. This strikermechanism is also intended to improve noise and vibrationcharacteristics and is designed to reduce or eliminatechucking, squeak and rattle. It is not designed to take uphigh stresses that may occur at a car accident and a collision.
    JP2004276884 illustrates another example of a structure forThis solution illustrates a striker device holding striker mechanisms.intended for the rear cabin lock having side plates,the locking pin. The side plates are made deformable throughselection of material and its general design. No specialarrangement is disclosed with the aim to increase thedeformability of the mechanism.
    Still another solution is disclosed in GB2351709. Thisinvention concerns a safety arrangement adapted to minimizethe risk of injuries for an occupant within a vehicle such asbus or train in the event that a heavy goods vehicle, lorry, the vehicle is involved in an accident. The invention is basedon keeping an element in a retracted position, having a catch means adapted to be released when subjected to a sudden deceleration. In such a situation the retaining element isenabled to move to an operative position in order to retain anoccupant in a desired position. The solution is complicatedand intended for retaining a person, not primarily amechanical component in the vehicle.
    All these variants have a number of disadvantages. One is thatthey are relatively complex and therefore expensive tomanufacture and install. The different solutions also take upa lot of space and add to the vehicles weight.
    A number of similar solutions, regarding locking strikers,exist in the market but none of these prior known devices/-systems illustrates a design that only requires a small space,comprises very few parts, and still is strong enough to keep e.g. a vehicle bed in place at a collision.
    SUMARY OF THE INVENTION One object of the present invention is to solve the abovementioned problems and to provide a simple design of a locking device that will sustain high stresses when suddenly loaded.
    Another object of the invention is to design a locking devicethat will be able to absorb high loads and deform smoothly in a controlled and predictable way.
    Another object of the invention is to design a locking device containing very few components.
    A further object of the invention is that the locking device must take up minimal space.
    A further object of the invention is that the design should not add weight to the locking device or to the vehicle.
    A further object of the invention is that the locking deviceshould not be more complicated to manufacture, install or use than o conventional locking device.
    These and further objects and advantages is achieved by theinvention by a locking device designed in accordance with the features recited in claim l and 6.
    The invention relates to a locking device designed with acrash absorbing element for keeping the device locked alsowhen subjected to high loads/stresses. The invention alsorelates to a method for providing a locking device with a crash absorbing function for keeping the device locked also when subjected to high stresses.
    The locking device is primarily intended for keeping a vehiclebed locked to the framework of the vehicle cabin during acollision, even if high loads is exerted during the collision.The locking device keeps the bed down in its closed positionand protects thereby the passengers inside the cab frompotential heavy objects from being released and thrown out ofthe storage compartment under the bed. The locking devicetakes up energy that occurs in a collision/crash by deformingin a controlled and predictable way.
    The locking device is preferably manufactured by metal, likesteel, and the locking pin will deform due to at least onerecess arranged in the metal near preferable one side of thelocking pins attachment onto the base plate of the lockingThe recess(es) device. are arranged to weaken the metal on this one side of the device and to balance the strength on the both sides of the locking pin in such a way that the lockingpin will be displaced/deformed substantially equally on bothsides of its attachments when subjected to high stresses, likea deceleration in excess of a predetermined threshold. Due tothe design the locking device will not take up any more spacethan a conventional locking device and, due to no addedcomponents, it will be very cost efficient to manufacture. Itsstrength will not affect the function of the device at normal strains/loads.
    The main advantages of the inventive solution are that thelocking device according to the invention will result inhigher crash safety and roll over crash safety and still doesnot need any more parts. It will not take up any more spaceand will be cost effective to manufacture and assemble/- install.
    Further features and advantages of the invention will beapparent from the following, more detailed description of the invention and the accompanying drawings and the claims.
    BRIEF DESCRIPTION OF THE DRAWINGS The invention is described below in some preferred embodiments illustrated in the accompanying drawings.
    Figure 1 illustrates a perspective view of a lower bed in avehicle, resting on a framework of the cabin below the bed, and covering a storage compartment located below the bed.
    Figure 2 illustrates a perspective view of the part of thebeds locking device that is mounted in the frame work of the cabin, below the bed.
    Figure 3 illustrates a perspective view, and in more detail, the locking device shown in figure 2.of variations Figure 4a-c illustrates plan views, from above, of the locking device part disclosed in figures 2 and 3.
    Figure 5 illustrates a side view of the locking device part shown in figures 2-4.
    DESCRIPTION OF PREFERRED EMBODIMENTS The invention thus relates to a locking device designed with aload absorbing part/element for keeping the device locked alsowhen subjected to high loads/stresses, which may occur during a traffic accident.
    Figure 1 illustrates a perspective view from below of a lower bed l installed in a vehicle/truck (not shown), resting on a part of the framework 2 of the vehicles cabin, and covering astorage compartment (not shown) located below the bed l. Thebed l can be folded up against a rear wall of the cabin (not shown), by means of hinges 3. When in the horizontal useposition the bed l is resting on the framework 2 and is lockedto this by preferable two locking devises 4 according to the invention, one first part 4a is mounted on the bed l and one second part 4b is mounted on the frame work 2.
    Figure 2 illustrates a perspective view of the second part 4bthat is mounted on the below the bed of the locking device 4 (see figure l) frame work 2 of the cabin, (not shown). The first part (not shown) of the locking device 4 comprises a conventional hooking mechanism for engaging into the pin 5 installed in the second part 4b of the locking device 4. Thissecond part 4b of the locking device 4 comprises mainly ofthree components welded together, a base plate 6 comprising an upper metal element 6a and a lower metal element 6b, attached to each other by e.g. welding, and the locking pin 5. In the upper metal element 6a at least one, preferably two, recesses 7 are arranged in order to weaken the metal of the upper metalelement 6a near the inner attachment of the pin 5. Holes 8 are provided (see also figure 3), both in the upper and lowermetal elements 6a-b for screwing the second part 4b of thelocking device 4 to a beam 9 in the frame work 2 of the cabin.
    The outer attachment 5a of the locking pin 5, located in the lower metal element 6b, will be somewhat weaker due to the design of base plate 6, than the inner attachment 5b of the pin 5, due to less material in the base plate 6 in thisregion, and due to that the inner attachment 5b of the pin 5is supported by the upper and lower metal elements 6a,b of theIn a situation base plate 6, installed to the framework 2. where the locking pin 5 is really loaded/stressed, such as in a traffic accident, the pin 5 will bend forwardly, in the direction of the forces occurring in the collision. If norecesses 7 were arranged in the upper metal element 6a the pin5 would bend in an angle, as the outer attachment 5a is weakerthan the inner attachment 5b of the pin 5, and the risk ofbreaking it completely would be significant. By arranging oneor more recesses 7 in the upper metal element 6a the upper metal element 6a is weakened at the inner attachment 5b of the pin 5 and the metal will deform in a balanced and smooth way.
    Figure 3 illustrates a perspective view more in detail of the second part 4b of the locking device shown in figure 2. The locking device 4 (see figure l) is preferably manufactured by metal, like steel, and two recesses 7 are here arranged in the base plates upper metal element 6a, for weakening this metal on at least the side near the locking pins 5 inner attachment.
    This is intended for deforming the base plate 6, i.e. its upper metal element 6a, substantially equally on both sides of the pin 5, in the region of the pins 5 attachments 5a,b, when the locking pin 5 is subjected to high stresses, like adeceleration in excess of a predetermined threshold, and forbalancing the strength of the locking pins 5 two attachments in the base plate 6.
    Due to the design the locking device 4 will not take up anymore space than a conventional locking device and, due to noadded components, it will be very cost efficient to manufac-ture. The weakened strength of the locking device 4 will not affect the function of the device at normal use/loads.
    Figure 4a-c illustrates plan views from above of differentdesigns of the recesses 7 arranged into the upper metaldisclosed in element 6a of the locking device 4 (see figure l) figures 2 and 3. The recesses 7 are arranged at an angle d andeach recess's 7 inner part ends with a substantially circularhole 8 in order to avoid crackings in the metal. The recesses7 create a tail/tongue ll in the upper metal element 6a and onthe inner attachment 5b side of which the locking pin 5 is the locking pin 5 is attached on the outer and attached, i.e. weaker attachment 5a side of the tail/tongue ll. The lockingpin 5 is at its outer attachment 5b side attached to the lowermetal element 6b of the base plate 6. The tail/tongue ll willpartly raise and bend when a high force is exerted on the pin5, e.g. when the vehicle is subjected to a collision and thebed l strives forwards in the vehicle/cabin.
    Figures 4a-c illustrates, as mentioned, different designs ofthe recesses 7. In figure 4a is illustrated a short variant of the recesses 7, arranged with an angle d in relation to the pin 5. In figure 4b the recesses 7 are designed with more depth/length, and each recess 7 is somewhat curved, and infigure 4c the recesses 7 longer but substantially straight,still with an angle d in relation to the pin 5, but not curved in this case.
    Figure 5 illustrates a side view of one part of the lockingdevice 4b shown in figures 2-4. In this figure is more in detail illustrated the attachments 5a,b of for mounting ontothe frame work 2 (se figure l) of the cabin. In the middle isshown the locking pin 5 and one of its attachments to theupper metal element 6a, which in turn is positioned on the tail/tongue ll defined by the recesses 7.
    The invention also concerns a method for producing a lockingdevice 4 with a load absorbing function for avoiding thelocking device 4 to break, 4 locked, and for keeping the locking device when subjected to high stresses.
    The above description is primarily intended to facilitate theunderstanding of the invention. However the invention is ofcourse not in any way restricted to only the disclosedembodiments, but many possibilities to modifications would beapparent to a person skilled in the art within the scope ofthe invention without departing from the basic idea of the invention as defined in the appended claims.
