    REAR PANEL UNIT AND A TRAILER WITH A REAR PANEL UNIT Technical Field The present disclosure relates to a rear panel unit, and in particular toa fastening arrangement for a rear panel unit adapted to be mounted on aboat trailer.
    BackgroundThere are many types of trailers on the market. A trailer is generally used to be towed behind a vehicle, for instance a car. The trailer can bedesigned for different transportation purposes. For instance an open trailer fortransportation of loose items, gardening items such as plants, or larger itemsthat can not fit in a car, such as furniture. The trailer can also be speciallydesigned to transport animals like horses, or other vehicles, such as boats ormotor cycles. Quite often the trailer has a rear panel on which auxiliaryequipment such as lighting, number plate, signs, holders and the like isarranged. When loading a cargo onto the trailer, the rear panel needs to bemoved so that the cargo can be loaded and/or unloaded without colliding withthe rear panel. A way to solve this is to provide a detachable rear panel. Thedetachable panel can be fully detached and put aside on the ground whenloading the cargo. A problem with this type of solution is that a user mayforget the panel on the ground, and subsequently drive off without theequipment or even run it over with the car, which is of course both costly anda hassle. A way to solve this is to arrange a semi detachable panel, which isarranged to be released at one end, and moved to the side but still attachedto the trailer on another side. ln that way, it is ensured that the equipmentalways is attached to the trailer. ln order to fasten the panel/equipment, alatch fastener may be used. However, a latch fastener usually requiresseveral operation steps in order to attach and detach the panel, which is timeconsuming for the user. Also, using a latch fastener is a risk of pinchingoneself during fastening. Therefore, there is a need for a better solution.
    Summarylt is an object of the present invention to provide an improved solution that alleviates the mentioned drawbacks with present devices. Furthermore, itis an object to provide a rear panel unit which can be operated in a singlemanoeuvre. lt is an object of the present invention to provide a rear panel unitwhich can be operated easily and swiftly while a cargo is to be loaded onto(or off) a trailer. The trailer may be any trailer that has a rear panel and/orequipment attached to the trailer that needs to be temporarily moved out ofthe way off a loading region during for instance loading or servicing.
    This may be accomplished by a rear panel unit adapted to be mountedon a trailer. The rear panel unit comprises a main part adapted to be attachedto the trailer, and an auxiliary part. The rear panel unit further comprisesconnecting means. The connecting means is arranged to connect theauxiliary part to the main part in a first position. The connecting means allowsthe auxiliary part to move between a first position and a second positionrelative to the main part. The rear panel unit further comprises a coupling unitarranged to couple the auxiliary part to the main part in the first position. Thecoupling unit comprises an engaging member and a receiving member. Thereceiving member is adapted to receive the engaging member. The receivingmember comprises resistance means such that when the engaging memberand the receiving member are engaged, the resistance means prevents theengaging member and receiving member from detachment.
    A rear panel unit of the kind is easy to operate. The coupling unit maydue to the engaging member and the receiving member allow coupling by asingle manoeuvre operation, and may not require a two-hand grip, as currentsolutions may require. An engaging member and a receiving member mayprovide a single movement operation, and be kept in place securely by theresistance means. The resistance means may preferably be a part of thereceiving member, and be arranged such that the engaging member, whenfully received in the receiving member, is prevented from release. Preferably the resistance means is incorporated in the receiving member and does not 3 need additional manipulation. This is an advantage since loading a cargonormally may be somewhat of an effort, and may require precision andmuscle. ln order to facilitate the entire activity of loading, the activities pre-loading and preparing the cargo as effortless as possible, may save time andeffort for the operator. By allowing any auxiliary equipment be attached to thetrailer with a rear panel unit according to the invention, the auxiliaryequipment may be easily temporarily detached, and subsequently beattached again. The attachment may thus be performed in a single movementby pressing the engaging member into engagement with the receivingmember. The detachment may be performed in a single movement by pullingthe engaging member out of engagement from the receiving member. Asingle manoeuvre is advantageous in many ways. For example, duringloading you may need your hands in many places at a time, and a swiftmanoeuvre may facilitate the entire operation. Further, when loading orunloading for instance a boat, a user needs to reverse the trailer close to thewater. lt is a possibility that the user forgets to move the auxiliary partbeforehand. This leads to the fact that the user already stands at least partlyin water. ln such event it may be ofgreat use to easily move the auxiliary partout of way without effort, since it may be harder to reach or harder to get agood grip if many manoeuvres are required.ln an embodiment, the engaging member may be brought into engagement with the receiving member by surpassing an obstructing meansof the receiving member. This is an advantage, since the obstructing meansmay provide engagement when needed. The obstructing means may be forinstance a narrow slot, a hole, a profile or the like that requires certain forcefor the engagement means to surpass. Preferably, the obstructing means areconfigured so that the engaging means may be brought into engagementafter having applied a certain force to the coupling unit. Subsequently, theengaging member is brought into engagement with the receiving member andkept in place by the resistance means until a certain force is applied in theopposite direction, such that the engaging member disengages from the receiving member. 4 ln one embodiment, the resistance means may be configured toprevent detachment of the engaging member for forces applied in asubstantially |inear direction. By substantially |inear, it is meant in thelongitudinal direction of the engagement member. Preferabiy, the longitudinaldirection of the engagement member coincides with the direction of the initialmovement of the auxiliary part relative to the main part upon release. Theresistance means may also be configured to prevent detachment of theengaging member for vibration forces. This is an advantage since a trailerquite often may be affected by vibrations. This may be caused by for instancevibrations travelling from the towing vehicle and from the irregular load.Further, a trailer may be transported on bumpy terrain, such as bumpy forestpaths or gravelled roads.ln one embodiment, the obstructing means may be resilient so that it yields for the engaging member when the engagement member is broughtinto engagement with the receiving member. To clarify, the obstruction meansmay bend, yield, give in by the forces applied by the engagement memberwhen it passes the obstruction means and thereby is brought intoengagement with the receiving member. The engagement member may thusbe hard. By hard it is meant harder than the engagement member such thatthe receiving member gives in for the forces from the engaging member. Theobstructing element may thus be a resilient component. A component of thetype may be a bushing, a ring a coating or the like. lt is also possible that thereceiving member is spring loaded and that the resilience is obtained by thespring. The material may be any material suitable, such as an elastomericmaterial like rubber, silicone or another suitable resilient material. Theresilient material may thus be adapted to withstand the forces and vibrationsresulting from at least normal use of the trailer. The material may be amaterial resistant to corrosion. This may be an advantage since for instance aboat trailer may be used in salt water, which may be a corrosive environment.Further the use of a type of resilient material may prevent rattling. This maybe since the resilient material is flexible enough to provide a close fit of theengaging member and may dampen any noise. ln order to provide resistance, 5 there may be friction between the engaging member and the receivingmember. The coupling unit may further be sized to suit the specific installationand requirements. A trailer which is adapted to travel in a certain terrain orspeed may for instance require a certain configuration of the coupling unit,while another trailer may require another configuration of the coupling unit. ln one embodiment, the obstruction means forms an integral part of theresistance means. This means that the obstruction means may be construedof the resilient material and also may form the resistance means. Forinstance, the obstructing means may be that the resilient material forms anarrow entrance of the receiving member. When the engaging member iskept in place by the receiving member, any friction of the receiving membermay form part of the resilient means, as well as the obstructing means. ln one embodiment, the engaging member may be a ball stud. Further,the receiving member may be a socket. This type of coupling may provide asteady and substantially rattle free connection. The ball stud may beconfigured such that it comprises a ball on an engaging end. The ball may bereceived in the socket. The socket may be resilient, and give in by the forceapplied from the ball when pushed into engagement. The entrance of thesocket may thus have a narrower circumference than that of the boll. Thesocket may thus, when engaged, substantially enclose the ball. ln that way,the socket may hold the ball in place. The socket may be of a resilientmaterial. The ball stud may be of a harder material, at least a material with ahardness that may be received by the receiving member and retained in thereceiving member. The socket may be arranged on the main part as required.Alternatively, the socket may be provided on the auxiliary part. The main part,or the auxiliary part, may thus be adapted to include a socket. ln the sameway, the ball stud may be arranged on a corresponding part, either main partor the auxiliary part. lt is of course possible that the coupling unit may beattached to a distance piece or the like in direct connection to the main part orthe auxiliary part in order to be provided on the right distance to the main/auxiliary part. 6 ln one embodiment, the connecting means may comprise a rai| andcorresponding gripping means. The gripping means may be arranged tomove along said rai|. An example of a rai| type connecting means withcorresponding gripping means may be for instance wherein a rai| is in theshape of a slot and a corresponding gripping means is in the shape of astud/screw/pin. ln that case the stud may be arranged to slide in the slot inorder to obtain a relative movement between the auxiliary part and the mainpart. The slot may be linear or a splined path. Another example is that thecorresponding gripping means may also be rollers arranged to roll along therai| at a certain path in order to lead the auxiliary part. By providing a rai| andcorresponding gripping means, the auxiliary part may be led towards anyposition, and still be connected to the main part and/or trailer. The rai| mayequally be either linear or provide a non linear path. ln one embodiment, the pivotal connecting means may comprise ahinge which may allow pivotal movement of the auxiliary part relative to themain part. ln that way, the auxiliary part may be allowed to rotationally moverelative to the main part at an angle suitable. Preferably, the hinge may allowa pivot such that the auxiliary part moves out of a loading region whenattached to a trailer. The hinge may be arranged so that the rotationalmovement may be done in the plane parallel to the ground, i.e. towards thesides of the trailer. Alternatively, the hinge may be arranged to allow rotationin another suitable direction, for instance downwards.
    Alternatively, the connecting means may be another type of pivotingmeans that may provide a pivoting movement in more than two dimensions.This may be a swivel joint or the like. ln some embodiments a rai| and corresponding gripping means maybe used in combination with a hinge, or any other suitable pivotable means.For instance, the auxiliary part may be arranged to be pushed in alongitudinal direction in a slot, and when in a certain position be pivotedtowards an angle in order to obtain a second position. The combination of the two may be done in any suitable order. 7 ln one embodiment, the auxiliary part may comprise one of thefollowing: a lamp unit, a number plate, a sign, a cable holder, equipmentholder. This is an advantage, since for instance a lamp unit or a licencenumber plate, which normally must be on a trailer towed by a car, may be inthe way while loading cargo. lt is a great advantage to be able to move theauxiliary part out of way. Especially, it may be an advantage to be able toswing the auxiliary part with a single manoeuvre. ln one embodiment, the rear panel unit further may comprise a keeperarranged to keep the auxiliary part in a second position. This is an advantage,since when in a second position, it may be undesirable that the auxiliary partay accidentally move out of position. lf the auxiliary part is allowed to moveuncontrollably, it may damage the cargo during loading. The keeper may forinstance be a wire, a snap type lock, a hasp, a latch or the like.
    A second aspect of the invention is to provide a trailer for transportingcargo. The trailer comprises at least one rear panel unit according to anembodiment as previously described. ln one embodiment, the auxiliary part may be movable between a firstposition and a second position. ln one embodiment, the auxiliary part ismovable between a first position and a second position at an opening anglerelative to the first position. The opening angle may be at least 90 degrees.This is an advantage since this may ensure that the rear panel unit staysclear of a loading region. The loading region may extend across a major partof the trailer from one side to the other where a cargo may be loaded. ln one embodiment, the opening angle may be at least 180 degrees.This is an advantage since an opening angle of 180 degrees ensures that thewhole trailer remains as short as possible, which may be an advantage whenreversing for instance. ln one embodiment, the opening angle may be about 250-270degrees, or more. An opening angle as large as possible may provide a rearpanel unit which does not substantially extend further to the side than thedistal end. This is an advantage since the auxiliary part, when in a secondposition, does not add either considerable length or width to the trailer. 8 ln one embodiment, the trailer may be a boat trailer. Quite often thetype of rear panel unit may be well needed on a boat trailer. This is because aboat trailer loads and unloads its cargo near water. lt may therefore be easierto avoid putting the rear panel unit aside, since it may end up in water, or berun over while reversing the vehicle towards the water for loading orunloading the boat. Since a boat is wide, the lamp units on either left or rightside on the rear may collide with the cargo during loading and/or unloading. ltmay therefore be a great advantage to be able to move them out of way,using as few operation steps as possible, preferably one, and the only use ofone hand. Of course, it has its advantages to use a rear panel unit on anytrailer for of any use.
    While the present invention has been described with reference to anumber of preferred embodiments, it will be understood by those skilled in theart that various changes may be made and equivalents may be substituted forelements thereof without departing from the scope of the invention. lnaddition, many modifications may be made to adapt a particular situation ormaterial to the teachings of the invention without departing from the essentialscope thereof.

    Description of Embodiments The present invention will be described more fully hereinafter withreference to the accompanying drawings, in which preferred embodiments ofthe invention are shown. This invention may, however, be embodied in manydifferent forms and should not be construed as limited to the embodiments setforth herein; rather, these embodiments are provided so that this disclosurewill be thorough and complete, and will fully convey the scope of the inventionto those skilled in the art. ln the drawings, like numbers refer to like elements. ln fig. 1 it is shown a perspective view of a rear panel unit 1 accordingto an embodiment of the invention. The rear panel unit 1 has a main part 2 and an auxiliary part 3. The main part 2 is attachable to a trailer, not shown, via a frame connector 25. The main part 2 can be attached to a side beam130 on the trailer, such that is fixed, for instance by screws or by welding. ltmay be an advantage if the frame connector is detachable, in the event ofservicing or cleaning. ln fig. 1, the auxiliary part 3 and the main part 2 areconnected to each other via connecting means 4, such as a hinge. The hingeallows the auxiliary part 3 to rotationally move relative the main part 2between a first 10 and a second position 20. The rear panel unit 1has acoupling unit 5 which connects the auxiliary part 3 to the main part 2 in a firstposition10. The first position 10 is a position when the auxiliary part 3 isarranged towards the main part 2, and when the trailer is ready for use. Thecoupling unit 5 ensures that the auxiliary part 3 and the main part 2 does notaccidentally detach. During operation of the trailer, the auxiliary part 3 isnormally coupled via the coupling unit 5 to the main part 2, to keep theauxiliary part 3 in place. ln Fig.1 the coupling unit 5 is arranged at a distancefrom the connecting means so as to create a lever arm and more efficientlyhold the auxiliary part 3 in the first position 10.
    Fig. 2 is similar to the embodiment show in fig. 1, with the differencethat the coupling unit 5 is arranged at another location than in fig. 1. Thecoupling unit 5 is here arranged below the main part 2. Depending on theequipment to be attached by the auxiliary part, the coupling unit 5 may bearranged anywhere suitable. Fig. 2 shows the coupling unit 5 in a disengagedstate. As seen, the coupling unit has a receiving member 51 and an engagingmember 52. The receiving member 51 is adapted to receive the engagingmember 52. When engaged, the engaging member 51 is placed inside thereceiving member 52.
    Referring now to figs. 3 and 4, wherein a top view of a rear panel unit 1according to an embodiment of the invention is shown. ln fig. 3, the auxiliarypart 3 is in a first position 10. ln this first position 10, the coupling unit 5 canbe engaged. ln fig. 4, the auxiliary part 3 is in a second position 20, andthereby pivoted away from the main part 2. The connecting means 4 is here ahinge and is arranged to allow the auxiliary part 3 to pivot by an opening angle oi. The opening angle oi depends on the hinge used, but it is preferable 11 that an opening angle oi such that the auxiliary part stays clear of a loadingregion 180 of the trailer 100, in order to avoid collision. E.g. the opening angleoi may be about 90 degrees, about 180 degrees or about 250-270 degrees.When in a second position 20, the auxiliary part 3 may be held in place by akeeper 6. ln that way, the risk that the auxiliary part accidently swingsuncontrollably by the hinge 4 when loading and/or unloading a cargo may bereduced. The keeper may be a wire, hasp, a magnet or the like.
    Referring now to figs. 5-9, showing alternative embodiments. Theconnection means 4 is here a rail 41 and corresponding gripping means 42.ln fig. 5, the rail 41 and corresponding gripping means 42 are arranged toallow movement sideways, moving the auxiliary part 3 towards the side of thetrailer. The rail can be arranged along a length of the rear panel unit 1. Forinstance, if the rear panel is a number plate, the rail can be arranged along atleast a part of or the entire length of the number plate, in order to move thenumber plate out of way. The coupling unit, not shown, may be arranged sothat it engages when the auxiliary part is brought to its first position. ln thesame way, it may disengage when moved out of position along the rail. Thelongitudinal direction of the coupling unit, i.e. the direction for engagementalong which the engaging member engages in the receiving member maycoincide with the moving direction of the auxiliary part 3. ln figs. 6 and 7, the connection means is also a rail 41 andcorresponding gripping means 42. ln this specific installation the rail 41 is alongitudinal slot arranged in the frame connector, and the gripping means 42is a screw/pin arranged in the beam and adapted to slide in the slot. The slotis arranged to allow movement in a longitudinal direction of the beam 130. lnits first position 10, the rear panel unit 1 is in its innermost position, as shownin fig. 6. When sliding the panel unit 1 backwards towards an end of the slot,as shown in fig. 7, the panel unit becomes free and may be able to rotatearound the screw towards the second position 20. ln figs. 8 and 9, the rail 41forms part of the main part 2, extending in a path for the auxiliary part 3 tomove along. ln figs. 8 and 9, the rail 41 extends at an angle oi relative to thebeam. ln that way, the auxiliary part can move along the rail towards a side of 12 the trailer. ln all the described alternative embodiments shown in figs. 5-9, acoupling unit may be used to couple the main part 2 with the auxiliary part 3 inthe first position 10. lt is to be understood that the coupling unit 5 can bearranged anywhere suitable, for instance so that the auxiliary part 3 couplesthe coupling unit 5 from either the front, back or from the side, depending onthe movement allowed by the connection means 4.
    Referring now to fig. 10, showing a schematic view of a coupling unit 5as described and relevant to all embodiments. The coupling unit 5 comprisesan engaging member 52 and a receiving member 51. Upon connection, thereceiving member 51 receives the engaging member 52. The engagingmember 52 may be a ball stud. The ball stud comprises a ball 523 at anengaging end of the ball stud, and a stud 521 at the opposite end. Betweenthe ball 523 and the stud 521 is a neck 522, on which the ball 523 is attached.The receiving member comprises a space 513 in which the ball 523 may beenclosed. ln order to ensure engagement, the receiving member comprisesan obstructing means 512. The obstructing means shown in fig. 10 is acircumferential inward collar 513 which has a diameter smaller than that ofthe ball 523. The receiving part 51 may hence be resilient in order to allow theball 523 to enter the receiving member 52, and surpass the obstructingmeans. While coupled, the receiving member 51 encloses a part of the ball523, and the inward collar 513 is arranged towards the neck 522. ln order toprevent accidental disengagement, the receiving member 51 comprisesresistance means 511. The resistance means 511 may be integral with thereceiving member 51. For instance, the resistance means 511 may beprovided by friction between the engaging member 52 and the receivingmember 51. Further, the inward collar 513 may provide resistance means 511such as to prevent accidental detachment. The obstructing means 512 maythus be an integral part of and the resistance means 511. The resilience ofthe receiving member 51 may be determined based on the specificrequirements on the installation based on for instance use and otherconditions. For instance, a trailer adapted for use in bumpy terrain mayrequire a steadier coupling unit, and thus be prepared for that. That may be 13 accomplished by e.g. choosing a harder material or larger size of the ball 523relative the obstructing/resistance means 512/511 which may require higherforce to engage with the engaging member 52, and thereby harder todisengage. The coupling unit 5 may hence be dimensioned and adapteddepending on the installation, and the purpose and placement of the auxiliarypart 3.
    Referring to figs. 11 and 12, which show a trailer 100 having a rearpanel unit mounted onto the rear of the trailer 100. This specific trailer isconfigured to transport boats. The trailer has a towing end 110 and a rear end120. On the rear end 120 it is shown two rear panel units 1a, 1b, each holdinga lamp unit. The rear panel units 1 are each connected to the trailer 1 on aside beam. ln fig. 5, one rear panel unit 1a is shown when the auxiliary part isin a second position 20, and swung off to the side relative to the main part 2.The other rear panel unit 1b is shown when the auxiliary part 3 is in a firstposition 10, and thereby placed close to the main part 2. As can be seen,when the rear panel unit 1 is rotated to the side in a second position 20, itleaves a clear way to load the boat. Since a boat normally is loaded from therear, any parts on the rear end 120 of the trailer 100 must be moved out ofway to avoid collision. ln fig. 6, the solution is shown in a perspective view. ln figs. 11 and 12, with exemplary clarifying reference to figs. 3-4, therear panel unit 1 is connected to a side beam 130 of a trailer 100. The mainpart 2 of the rear panel member 1 is connected to a side beam 130 on aframe of a trailer 100 via a frame connector 25. The connection is such that adistal end 15 of the rear panel unit 1 is, when in a first position 10, placed to afar side of the trailer 1. The hinge 43 is also placed at a distal end 15, andmay represent the side of the rear panel unit 1 that is arranged most far to theside, as seen from the rear end 120. This results in that when the auxiliarypart 3 is disengaged from the main part 2, and pivoted to its side, the rearpanel unit 1 stays entirely clear off the loading region 180 of the trailer 100.The connecting means may be arranged to allow a pivoting opening angle oi of at least about 90, 180 or up to 270 degrees. 5 14 ln the drawings and specification, there have been disclosed preferredembodiments and examples of the invention and, although specific terms areemployed, they are used in a generic and descriptive sense only and not forthe purpose of limitation, the scope of the invention being set forth in the following claims.
