    BUNK LOCKING ARRANGEMENT FOR A VEHICLE TECHNICAL FIELD The present invention relates to a bunk locking arrangement for a vehicle such as a truck or a trailer.BACKGROUND A vehicle such as a truck or a trailer for transporting lumber is generally equipped with a bunk forholding the lumber in place, said bunk comprising a number of bolsters that are arrangedtransversally on the vehicle. Each bolster is connected to two stakes, one at each end, that extendessentially vertical from the vehicle and are intended to hold the lumber or logs of wood securely inplace when the truck or trailer is loaded.
    For reasons of safety and reliability, the stakes must be able to withstand large forces from thelumber pressing against them as well as vibrations when the vehicle is travelling at high speed or onuneven roads, and they are therefore generally fixed with regard to the bolster. When the vehicle isempty, i.e. not loaded with lumber, the stakes are not subjected to forces from the lumber itself butthere is constantly a risk of damage due to vibrations created when the vehicle moves on the road. lt is often desired to be able to decrease the height of the truck or trailer to facilitate transport or toenable loading with other goods, and also to eliminate the risk of vibrations damaging the bunk. lfthe stakes are fixed on the bolster by screwing or welding it is often not possible to remove them in aconvenient and time efficient manner, but in some bunk arrangements the stakes are arranged to befolded or pivoted against the bolster to a horizontal position where they lie directly on top of orbeside the bolster, thus allowing for a more versatile use of the truck or trailer and at the same timeminimizing the risk of damage due to vibrations.
    However, if the stakes are pivotally arranged a locking arrangement is necessary to prevent anundesired pivoting or folding, and a plurality of such locking arrangements are known within the art.Examples are shown by USZQGSEGQ (White), US299G19 (Leach) or LJSZ-fiâšíšïïëšü (Berry), wheredifferent types of hitches are pivoted to lock the stakes, or by USZSRZZG (Tucker) or Dšßfifiâšê(Schlumbohm), where locking devices are put in place and secured by a simple lock such as a pin.
    A disadvantage of the known locking arrangements is, however, that they fail to secure the stakes ina reliable and safe way when the vehicle is not loaded with lumber. The locking arrangements aregenerally not able to withstand vibrations or wear and tear during long use on uneven roads, andthere is a therefore a risk that the stakes are loosened during transport and may pivot against thebolster or away from it, causing damage to the vehicle and also possibly to other vehicles, structuresor persons in the immediate vicinity. There is also a substantial risk that wear or damage to thelocking arrangements may cause the stakes to become loosened during transport when the bunk isloaded with lumber, resulting in possible additional damage by falling lumber that may result in veryserious damage.
    There is therefore a need for an improved locking arrangement to overcome the disadvantagesdescribed above, while at the same time maintaining the functionality of reduction of the height of avehicle such as a truck or a trailer.
    SUMMARY OF THE INVENTION The object of the present invention is to eliminate or at least to minimize the problems describedabove. This is achieved through a bunk locking arrangement according to the independent claim 1,while particularly advantageous embodiments are disclosed through the dependent claims.
    Thus, thanks to the invention, the bunk locking arrangement can secure the socket and thereby thestake normally mounted on the socket in the open position in which the stake extends essentiallyvertical from the bolster, and by the catch mechanism pulling on the hitch the socket is fixated and arelease of the socket of unwanted pivoting of the socket and stake can be prevented. Furthermore,by the secure hold and the constant pull of the catch mechanism, the wear and tear on the bunklocking arrangement due to vibrations can be decreased to increase the lifespan of the bunk.
    According to one aspect of the invention, the catch mechanism comprises an excenter means.Thereby, the catch mechanism can pull on the hitch by the excenter means being turned.Furthermore, by using an excenter means the advantageous effect of a pulling or tightening on thehitch is created with sturdy components that are able to withstand vibrations, dirt and general wearand tear.
    According to another aspect of the invention, the hitch is the first locking member arranged on thesocket and the catch mechanism is the second locking member on the bolster. Thereby, the formingof the connection between the hitch and catch mechanism can be achieved by pivoting the socket tothe open position without requiring manual guiding of the hitch. Preferably, the hitch comprises abeveled surface arranged to slide along the catch mechanism as the socket is pivoted from the closedto the open position, to allow the hitch to be guided by the catch mechanism itself and to fall intoplace around the catch mechanism when the socket has reached the open position.
    According to another aspect of the invention, a hitch release mechanism is provided and arranged torelease the hitch from the catch mechanism, said hitch release mechanism being operated bypivoting the socket in relation to the bolster. Thereby, the hitch and the catch mechanism can bedisconnected by guiding the socket itself and a manual operation of the hitch and catch mechanismalone is not required.
    Preferably, the hitch release mechanism comprises - a release element arranged on the hitch and having a release surface, and- a counter surface arranged in connection with the catch mechanism, wherein the hitch is arranged to be released from the catch mechanism by the release surfaceengaging the counter surface to push the release element and thereby also the hitch away from thecatch mechanism. This has the additional advantage that the hitch can be pushed up from the catchmechanism automatically through the interaction of the release element and the counter surface, sothat the entire process of releasing the hitch can be performed by operating the socket.
    More preferably, the release element is a pendulum pivotally arranged on the hitch and able to pivotto bring the release surface into contact with the counter surface. Thereby, the pendulum isautomatically activated by means of gravity when the socket is pivoted to allow the pendulum to swing. Furthermore, the pendulum can be pivoted away during other stages of the operation of thebunk locking arrangement to allow for a compact and convenient design of the locking arrangementitself.
    According to another aspect of the invention, at least one deformation element is provided andarranged on at least one of the bolster and the socket and able to receive and be at least partiallydeformed by the other of said bolster and socket when the socket is pivoted to the open position.Thereby, the socket can be received in the open position and its movement halted through acontrolled braking as the deformation element is compressed.
    Preferably, the at least one deformation element is arranged to be deformed further by pivoting thesocket away from the bolster beyond the open position, thereby allowing a movement to an extremeposition where the hitch and the catch mechanism can be disconnected before the socket is allowedto return to the closed position essentially parallel to the bolster.
    According to yet another aspect of the invention, the hitch comprises an adjustment element foradjusting the distance between the first attachment point and the second attachment point.Thereby, the locking arrangement can easily be adapted to fit different bunks and also tocompensate for wear and tear to the components creating an allowance in the locking arrangementto prevent the secure locking otherwise created by pulling on the hitch.
    Preferably, the adjustment element comprises a first through hole, said adjustment element beingmounted on the hitch and the first through hole being able to receive a pivot element at the firstattachment point to allow the hitch to pivot, and wherein the first through hole is further arrangedoff center in the adjustment element. Thereby, by turning the adjustment element around an axisthrough the hole, the distance from the hole to a forward end of the hitch that is arranged to interactwith the catch mechanism can be altered in a robust and easy manner. ln one embodiment, theadjustment element is mounted on the hitch by cogs on an outer circumference of the adjustmentelement cooperating with corresponding cogs on an inner circumference of a second through holeon the hitch. The cooperating cogs create a very large frictional force that prevents and undesiredturning of the adjustment element, even when subjected to very large forces or vibrations.
    Many additional advantages and benefits of the invention will become readily apparent to theperson skilled in the art in view of the detailed description below.

    DETAILED DESCRIPTION Fig. 1 discloses a bunk 1 with a bolster 2 arranged to be connectable to a vehicle such as a truck or atrailer, according to a preferred embodiment of the present invention. The term vehicle is hereinunderstood to mean a trailer for a truck as well as the truck itself, and it is to be noted that thevehicle may comprise a trailer only, and could also signify another structure on wheels on whichgoods such as lumber may be transported on roads.
    On each end of the bolster 2, stake arrangements 3 are mounted and each stake arrangement in thisembodiment comprises a socket 3 holding a stake 4. lt is to be noted that the socket 3 and stake 4could also be integrated into a single element and that what is said herein with reference to a stakearrangement comprising a socket and stake would also apply in the same way to such an integratedstake arrangement.
    The socket 3 is pivotally arranged on the bolster 2 at a pivot point 21 near an end of the bolster 2, sothat the socket 3 and stake 4 can pivot between a closed position where the stake lies essentiallyparallel to the bolster 2 (shown on the left hand side of Fig. 1) and an open position where the stake4 mounted on the socket 3 is at an angle to the bolster 2, preferably extending essentially verticalfrom the bolster 2. ln the open position, the bunk 1 can be loaded with lumber or similar goods,while the closed position is suited for facilitating transport of the vehicle while unloaded andprovides a reduction in height of the bunk 1. The vehicle may also be loaded with various goods inthe closed position, so that the vehicle can be used for transporting objects other than logs orlumber. lt may also be advantageous to store a trailer or other vehicle on another vehicle havingbunks in the closed position, to facilitate transport of the vehicle in question.
    Fig. 2a shows the bolster 2 and socket 3 of the left hand side of Fig. 1, with the socket 3 in the closedposition. Fig. 2b shows the same components in cross section, disclosing also the bunk lockingarrangement 5 according to a preferred embodiment of the present invention. The bunk lockingarrangement 5 comprises a first locking member 51 arranged on a first attachment point 32 on thesocket 3 and a second locking member 52 arranged on a second attachment point 22 on the bolster2. The first attachment point 32 is arranged to be closer to the bottom of the bolster 2 when thesocket 3 is in the open position (see Fig. 3-6). The bunk locking arrangement 5 is in a disconnectedstate in this Figure, meaning that the hitch and the catch mechanism are not interacting with eachother. ln this preferred embodiment, the first locking member 51 is a hitch 51 and the second lockingmember 52 is a catch mechanism 52, but it is to be noted that the opposite may be suitable in otherembodiments (i.e. the first locking member being a catch mechanism and the second lockingmember being a hitch).
    Fig. 2c show the components mentioned above from above, and the relative placement of the pivotpoint 21 and the first and second attachment points 32, 52 are shown.
    Fig. 3a-c discloses a first stage of connection where the socket 3 is pivoted away from the bolster 2towards the open position. The hitch 51 is operated by the pivoting movement of the socket 3 andpivots about the first attachment point 32 towards the catch mechanism 52. Thanks to a beveledsurface 54 on the hitch 51, the hitch 51 can slide upwards along the catch mechanism and fall downto enclose the catch mechanism 52 as the socket 3 is moved further towards the open position. The catch mechanism 52 is in this preferred embodiment operated by an excenter means, as will bedescribed further below.
    The hitch 51 further comprises a release element 53, here in the form of a pendulum, that is pivotallymounted on the hitch 51 itself and able to swing between a retracted position along the hitch 51 anda release position where it can act to release the hitch 51 from the catch mechanism 52, as will bedescribed in detail further below.
    Fig. 4a-4f disclose a second stage of connection, where the socket 3 has been pivoted far enoughaway from the closed position to allow the hitch 51 to fall into place on the catch mechanism 52 andbe held by it. ln this position, the socket 3 is held in place by means of the locking arrangement and isprevented from falling down, i.e. pivoting towards the closed position on the bolster 2. lt is howevernot locked and the hitch 51 could be disengaged from the catch mechanism 52 by vibrations if thesocket were allowed to be held in the second stage of connection when the truck or trailer is drivenon uneven roads.
    Fig. 4e and Fig. 4f also disclose at least one but preferably two deformation elements 61, 62 in theform of rubber buffers that are arranged on the catch mechanism 52 and able to receive the socket 3and be deformed to brake the pivoting movement of the socket 3 itself. ln the second stage ofconnection, the deformation elements 61, 62 are only deformed to a smaller degree to allow for alarger deformation in later stages of connection as described below. lt is also to be noted that thedeformation elements could in another embodiment be placed on the socket and receive the bolsterwithout additional alterations to the bunk locking arrangement.
    Fig. 5a-5f disclose a third stage of connection, where the socket 3 has been securely locked into placeby the bunk locking arrangement 5 by operating the catch mechanism 52 to pull on the hitch 51 andthereby fix the socket 3 in the open position, and also further deform the deformation elements 61,62. ln this preferred embodiment, the catch mechanism 52 is operated by turning the excentermeans to pull the hitch 51 further along the bolster 2 in a direction away from the socket 3. Thanksto the placement of the first attachment point 22 beneath the pivot point 21, i.e. closer to a bottomend of the bolster 2, a lever is formed between the first attachment point 22 and the pivot point 21and allows the socket 3 to be pulled into the locked position, i.e. the third stage of connection, bypulling on the hitch 51.
    The excenter means may comprise an excenter screw and is preferably turned manually by anoperator using a suitable tool, but may also be operated in other suitable ways. ln an alternativeembodiment, the bunk locking arrangement 5 could also be locked by the hitch being mounted on anexcenter means or similar and provide a pulling force along the bolster towards the socket when thatexcenter means is turned by an operator. Also, instead of excenter means or other excentermechanism, alternative embodiments could instead have an element that is slidable along thebolster and can pull on the hitch and be able to be fixed in place when a desired locking of the sockethas been achieved. Also, that element could also be biased by a spring or similar.
    Fig. 5e-f further disclose the deformation elements 61, 62 that are deformed further by the socket 3that presses against them by means of a deformation surface 63 on the socket 3.
    Fig. 6a-6c disclose a fourth step of connection where the bunk locking arrangement 5 has beenunlocked and the hitch 51 has been lifted from the catch mechanism 52. This is achieved through thesocket 3 being pivoted beyond the open position, i.e. moved to an angle from the closed positionthat is larger than the open position. This allows the release element 53 to swing free from itsretracted position in a hollow 56 in the hitch 51 towards a release position where it hangs down fromthe hitch 51. When the socket 3 is pivoted back to the open position from the position beyond, arelease surface on a bottom surface of the release element 53 engages a counter surface 55 on thecatch mechanism 52 and pushes the release element 53 itself and thereby also the hitch 51 upwards,away from the catch mechanism 52. Further pivoting of the socket 3 from the open position towardsthe closed position creates a retraction of the hitch 51 away from the bolster 2 and towards the lefthand side of Fig. 6a-6c, thereby disconnecting the bunk locking arrangement 5 and allowing thesocket 3 to be lowered towards the closed position. ln the position beyond the open position, thedeformation element(s) are arranged to be deformed and thereby allow a controlled operation ofthe socket 3 in relation to the bolster 2.
    Fig. 7a-7c show the hitch 51 according to this preferred embodiment. The hitch 51 may comprise aplurality, preferably three, layers having outer layers 51' arranged on either side of an inner layer51". This is advantageous in creating a strong and durable hitch able to withstand large forces andvibrations when the bunk locking arrangement 5 is locked, and also when manufacturing the hitchitself. The inner layer 51" has the hollow 56 in which the release element 53 can be held, while theouter layers 51' comprise a release element pivot 59 on which the release element 53 can bemounted by means of a pin or similar and be allowed to pivot into and out of the hollow 56.
    The hitch 51 further comprises an adjustment element 57, shown in Fig. 7b in a perspective view andshown mounted in the cross-sectional views of Fig. 7a and Fig. 7c. The adjustment element 57 is in itsmost basic form an essentially cylindrical structure having a first through hole 571 that is able toreceive a pivot element such as a pin at the first attachment point 22 to allow the hitch 51 to pivot.The inner layer 51" and outer layers 51' have a second through hole 581 in which the adjustmentelement 57 is mounted. lt is to be noted, however, that the adjustment element 57 may have othershapes also.
    The first through hole 571 is arranged off center in the adjustment element 57 so that the length ofthe hitch 51 from the first through hole 571 to the beveled surface 54 can be altered by rotating theadjustment element 57 in the second through hole 581. When the hitch 51 is mounted in the bunklocking arrangement 5, turning the adjustment element 57 in the second through hole 581 serves toadjust the distance between the first attachment point 22 and the second attachment point 32. Thisis especially advantageous when mounting the bunk locking arrangement 5 on bunks having differentmeasurements, or if the components of a bunk already having a bunk locking arrangement 5 becomeworn or damaged in such a way that it is no longer possible to achieve a secure hold of the socket 3through the interaction between hitch and catch mechanism. Altering the distance between the firstand second attachment points 22, 32 allows the bunk locking arrangement 5 to regain its ability tocreate a secure lock and thereby hold the socket stably in place.
    Preferably, the adjustment element 57 comprises some kind of friction means to prevent anundesired turning of the adjustment element 57 in the second through hole 581. The friction means can advantageously be cogs 58 mounted on an outer circumference of the adjustment element 57and arranged to cooperate with corresponding cogs on an inner circumference of the secondthrough hole 581 on the hitch 51. These corresponding cogs may be placed on the inner layer 51"only. As an alternative to the cogs, the adjustment element 57 may be held in place by an elasticbushing mounted between the adjustment element and the hitch itself, and alternatively other waysof securing the adjustment element in the hitch may also be used. ln another embodiment, the hitch may be manufactured through molding, for instance, andcomprise only one layer that extends over the entire width of the hitch 51 in the preferredembodiment described above. Such a molded hitch may be cut to form the hollow that houses thependulum and the through hole in which the adjustment element is placed.
    The operation of the bunk locking arrangement 5 will now be described in detail with reference tothe Figures.
    When the socket 3 and stake 4 are in the closed position on the bolster 2, the bunk lockingarrangement 5 is disconnected. ln order to place the socket 3 and stake 4 in the open position, aperson operating the bunk may manually grip the stake 4 or the socket 3 directly and pivot themaway from the bolster 2. When the socket 3 has been pivoted towards the first stage of connection,the hitch 51 has been pivoted towards the catch mechanism 52 so that the beveled surface 54 of thehitch 51 allows the hitch 51 to slide against the catch mechanism 52 and begin to fall into placethrough gravitational force around the catch mechanism 52 itself. As the socket 3 is pivoted further,to the second stage of connection, the hitch 51 has fallen down around the catch mechanism 52 andholds the socket in place but remains unlocked and can pivot but not fall down towards the closedposition. The person operating the bunk 1 may release the socket 3 and stake 4 without riskingdamage due to the socket 3 and stake 4 falling down, which allows for the raising of several stakes insuccession before starting to lock them, or for other actions that are needed when managing thebunks. ln order to lock the bunk locking arrangement 5, the operator uses a suitable tool to turn theexcenter means of the catch mechanism 52 in order to pull on the hitch 51 and fixate the socket 3 inthe locked position, or third stage of connection. The stake 4 is now held stably by the socket 3 andthe bunk 1 may be loaded with lumber or similar goods, but may also be transported in the openposition without risking damage due to vibrations.
    When the bunk locking arrangement 5 is to be unlocked and the socket 3 and stake 4 folded again,the operator starts with releasing the catch mechanism 52 by turning the excenter means to itsoriginal position. He then pivots the socket 3 and stake 4 further away from the closed position,beyond the open position which causes the release element 54 to fall from the hollow 56 in the hitch51 and pivot towards the counter surface 56 on the catch mechanism 52.
    Then, the operator continues to pivot the stake 4 and socket 3 back towards the closed position,which causes the hitch 51 to be lifted from the catch mechanism 52 and retracted as describedabove. Finally, the socket 3 and stake 4 are allowed to reach the closed position, lying essentiallyparallel to the bolster 2. lt is especially advantageous that the operation of the hitch 51, both when gripping the catchmechanism 52 and when being released from it, is performed solely by pivoting the socket 3 inrelation to the bolster 2. Thereby, the hitch 51 can be mounted inside the bolster 2 and socket 3 andbe protected from dirt and other damage, while a steady and reliable operation is neverthelessenabled. The operator then only needs to pivot the socket to the desired position and operate thecatch mechanism 52 from the outside of the bunk 1 by turning the excenter means.
    The invention is not to be seen as limited by the embodiments described above, but may be variedwithin the scope of the claims. lt is also to be noted that elements from the various embodimentsmay be freely combined with each other unless it is specifically stated that such a combination isunsuitable.
