Description

[0001] Retention system

[0002] Field of the invention

[0003] The present invention relates to a retention system that enables a mountable item, such as a storage container, to be releasably attached to a rack plate.

[0004] Background

[0005] Motorcycle travel is a convenient transportation method, particularly in congested city environments. To enable riders to transport goods, such as luggage and groceries, many motorcycles are fitted with a rack plate or luggage plate that extends from the rear of the motorcycle frame. Specially designed hard cases can then be semi-permanently mounted with screws to the rack plate, allowing users to open and fill the inside as needed. Other luggage, such as cases, boxes and bags can be mounted to the rack plate using flexible luggage straps that tie them down to the rack plate. A number of luggage straps need to be used to ensure a secure connection that won't result in the luggage sliding sideways during travel.

[0006] The semi-permanent attachment option requires the user to have bags that contain the goods to be carried, the bags then being loaded into the hard case mounted to the motorcycle for transport. It is not intended for the hard case to be removed easily, to minimise theft.

[0007] Tied down bags can be removed from the motorcycle, but quite a bit of time and effort is required to remove them and to reattach them securely enough for transport.

[0008] Additionally, many motorcycles are provided with a rack plate, also known as a cargo plate, as original equipment. Others have mounting points to which a specifically designed rack mounting system can be purchased from the manufacturer or by a third- party supplier. As each model of motorcycle is different, rack plate mounts are usually specific to the specific model of motorcycle. Hence, each rack mount system requires specific tooling and is thus fairly expensive. Many motorcycles have bike / motorcycle specific luggage systems that require boxes made specifically for the system.

[0009] There is a need to address the above, and / or at least provide a useful alternative.

[0010] The reference in this specification to any prior publication (or information derived from it), or to any matter which is known, is not, and should not be taken as an acknowledgment or admission or any form of suggestion that that prior publication (or information derived from it) or known matter forms part of the common general knowledge in the field of endeavour to which this specification relates.

[0011] According to a first aspect, there is provided a retention system for releasable attachment of a mountable item, such as a storage container, to a rack plate, wherein the rack plate is attached, or attachable to, a structure that is part of a moveable object, the rack plate having a first edge and a second edge, the retention system including: a socket element and a locking element that are capable of attachment to an outer surface of, or are a component of, a mountable item; the socket element slidable with respect to the rack plate to engage the first edge of the rack plate, whereby when the locking element slides beyond the second edge of the rack plate it displaces over the second edge to prevent further sliding movement.

[0012] According to a second aspect, there is provided a mountable item for releasable attachment to a rack plate, wherein the rack plate is attached to, or attachable to, a structure that is part of a moveable object, the rack plate having a first edge and a second edge, the mountable item including: a socket element and a locking element attached to an outer surface of the mountable item; the socket element slidable with respect to the rack plate to engage the first edge of the rack plate, whereby when the locking element slides beyond the second edge of the rack plate it displaces over the second edge to prevent further sliding movement.

[0013] According to a third aspect, there is provided a kit for attaching a mountable item to a structure that is part of a moveable object, the kit including: a rack plate having a first edge and a second edge, the rack plate being attachable to the structure; a socket element and a locking element that are capable of attachment to an outer surface of a mountable item; the socket element slidable with respect to the rack plate to engage the first edge of the rack plate, whereby when the locking element slides beyond the second edge of the rack plate it displaces over the second edge to prevent further sliding movement.

[0014] The kit may also include one or more mountable items, for example storage containers.

[0015] The mountable item may be either hard or soft sided, but preferably has a flat bottom surface that enables the retention system to be mounted to it. Base mounts may be provided to attach the socket element and / or locking element to a non-flat surface. An option may be provided to sew the socket element and / or locking element onto leather or material mountable items, such as pannier bags, soft sided toolbags, duffle bags, etc.

[0016] When the mountable item is a storage container, the retention system may include a mounting plate, that is inserted into the inside of the storage container. The socket element and locking element may be attached to the mounting plate through holes created in the storage container for the passage of screws. The mounting plate may include threaded holes for receiving screws. The mounting plate preferable covers the majority of the floor of the storage container. The mounting plate may be aluminium plate or another suitable material. It is preferable that the socket element and locking element is affixed to the mounting plate through the floor of the storage container and preferably sit against the bottom outer surface of the storage container.

[0017] Alternatively, the mountable item may have a retention system integrally formed as part of its base. The mountable item may be a storage container, such as a crate, toolbox, bag, or may be an item of equipment, such as a pump, generator, item of medical equipment, or a base plate of a different mounting system, for example such as those used for stackable toolbox systems.

[0018] The moveable object to which the rack plate is mounted may be a motorcycle, scooter, bicycle or trolley. It may also be a transport vehicle, such as a utility vehicle. The rack plate may be integrated into a rack or shelving system such as those in trains or airplanes.

[0019] The term "rack plate" is used to describe a plate like structure that is used as a framework for holding things or on which items are placed. A rack plate may be orientated generally horizontally or vertically, or at an angle.

[0020] The rack plate may be mounted to the frame of the moveable object, such as a motorcycle frame or bicycle frame.

[0021] The first edge may be a trailing, or back facing, edge of the rack plate with respect to the direction of travel of the moveable object. The second edge may be a leading, or front facing, edge of the rack plate with respect to the direction of travel of the moveable object. It will be appreciated that one or both of the edges may define one of the outmost edges of the rack plate. Alternatively, one of more of the edges may be an internal edge, for example, an edge of a cut-out section within the periphery of the rack plate.

[0022] In another embodiment, the rack plate may be affixed to an existing rack plate. In such an arrangement, the rack plate may include spacers that provide a clearance gap between the two rack plates, such that the socket element and locking element can be accommodated.

[0023] In another embodiment, the rack plate may be adapted to be mounted to the mounting system of the existing rack plate provided for that vehicle. In some cases, this may be a flat mounting arrangement, where the rack plate is affixed to the top surface of a horizontal mounting frame.

[0024] In other cases, the rack plate may be adapted to be mounted to a post mounted rack system, whereby cylindrical protrusions are provided on the underside of the rack plate that slot into open upright tubular posts of the rack system. This may preferably be a friction fit and / or aligned apertures could be provided to allow clips, such as an R-clip or D- clip, to secure the inserted protrusions to the tubular posts.

[0025] The socket element, when affixed to the mountable item, may create a socket between a recessed section of the socket element and the outer surface of the mountable item. One or more ridges may be provided to create one or more rear walls around the socket. The socket slides over the first edge and the rear wall engages against the first edge, preventing the mountable item from further forward movement. The locking element and the socket element are preferably spaced such that when the rear wall engages against the first edge, the locking element has cleared the second edge and displaces over the second edge. When the rack plate is in a generally horizontal orientation, this may mean the locking element drops downwards. When the rack plate is in a generally vertical orientation, this may mean the locking element moves sideways. Both forward and rearward sliding movement is therefore prevented. Upward movement of the container is restricted by the socket engaging over the first end of the rack plate.

[0026] The mountable item may be removed by lifting the locking element upwards, or away from the rack plate, out of engagement with the second edge of the rack plate and the mountable item slid backwards to disengage the first edge of the rack plate from the socket. The locking element may include a passage. A lockpiece, such as a lock pin, may be inserted into the passage to prevent upward movement of the front end of the mountable item. The passage may be a through hole, such that the lockpiece projects fully through the passage and engages the underside of the rack plate on both sides of the locking element. In another embodiment, the passage is a closed passage, with an opening in its back face. Inside the passage there may be housed a magnet, to releasably hold the lockpiece in position.

[0027] Alternatively, a retractable lockpiece may be fitted to the passage. When retracted, the lockpiece will allow the locking element and front end of the mountable item to drop down. When the lockpiece is released, the lockpiece will slide under the rack plate to prevent upward movement of the mountable item. Preferably, the retractable lock pin is pushed outwards by means of a compression spring. Preferably, the retractable lockpiece may be retracted by use of knob or pull cord.

[0028] In a preferred embodiment, the lockpiece may be part of a lock assembly. The lock assembly may include a lock housing and a lock lever. The lockpiece may be a sliding element, that is retained in the lock housing that is aligned with the passage of the locking element. The lock housing is preferably affixed to the underside of the rack plate. The lockpiece may be engaged using a lock lever, which may be operated from either side of the rack plate. The lock lever may be mounted on a lever pivot that operates the lockpiece.

[0029] According to an aspect of the invention, there is provided a rack plate for attachment to a structure, the rack plate having a first edge and a second edge, the rack plate being configured to have a mountable item secured to it, the mountable item having a socket element and a locking element, the locking element having a passage, the first edge being engageable by a socket element and the second edge being engageable by a locking element, the rack plate having a lock assembly, wherein the lock assembly includes: a lock housing affixed to one surface of the rack plate; a lockpiece, slidable within the housing to move between a retracted position and an extended position; a lock lever pivotally mounted to either the lock housing or the rack plate and pivotally attached to the lockpiece, such that rotational movement of the lock lever results in sliding movement of the lockpiece; whereby, in the extended position, the lockpiece projects through the passage of the locking element to secure the mountable item to the rack plate.

[0030] The lock housing is preferably affixed to the underside of the rack plate, opposite to the surface to which the mountable item is positioned.

[0031] In one embodiment, a lock lever pivot pin sits adjacent to the edge of the rack plate. The lock lever may be triangular in shape, with one corner attached to the pivot pin, one corner attached to the lockpiece pivot and the third corner having a lever or handle to actuate the lock assembly. Alternatively, the three points being the pivot pin, lockpiece pivot and handle form relative positions in a triangular shape, with the lock lever formed in a shape. When in the retracted position, the lock lever may project out from the side of the rack plate. When in the extended position, the lock lever may align with the side of the rack plate.

[0032] The lock assembly may include a wedge element. In one embodiment, the lockpiece engages with the wedge element such that it is pushed against the lower side of the lock passage, thus pulling the mounted item firmly downwards when the lockpiece is in the extended position. In an alternative arrangement, the wedge element is positioned on the lock lever and may engage with the underside of the rack plate when the lockpiece is in the extended position. The wedge element may engage with a depression or opening in the rack plate to hold the lock lever in the extended position.

[0033] The rack plate may be attached to the structure via fasteners. The rack plate may be attached to the structure via mounts. The mounts may be sized to space the rack plate from the structure sufficiently to allow the lock housing to sit between the rack plate and the part of the structure to which it is affixed. The part of the structure to which it is to be affixed may be a frame element comprising tubular sections. The mounts may include one or more passages that allow zip ties to be threaded through the passages and around the tubular sections to secure the mounts to the frame element of the structure.

[0034] If it is desirable to further ensure the retention of the mountable item, one or more retaining bolts may be used. Preferably, these would have a large head to allow hand tightening. Preferably, the retaining bolts would pass through the rack plate and mountable item to engage with one or more threaded holes in the mounting plate. These would also serve as a secondary means of retaining the mountable item should the socket element or locking element be damaged due to a collision or dropping the bike on its side.

[0035] Alternatively, a set of small "emergency" bolts and an appropriate Allen key could be stored in threaded holes on the forward side of the lock plate or in a small holder affixed inside the mountable item.

[0036] In one embodiment the strength of the socket element, locking element or any of the fixings can be tuned to fail in the event of an impact to reduce the probability of damage to the bike or injury to the rider. The tuning may be at a level of side loading that does not exceed the point where the bike frame, rack plate or its mounts are damaged.

[0037] An additional reinforcing plate may be mounted at the edge or across the centre of the rear socket element. Preferably, this plate would be retained by the plate mounting screws.

[0038] The socket element may be shaped to have a central body portion, a front tongue portion, two side wing portions and the rear wall. Alternatively, the socket element may be shaped to have a rear portion and two front tongue portions. The tongue portion(s) preferably includes a ramped leading edge to guide the socket element underneath the first edge of the rack plate. The two side wing portions may also have ramped leading edges. It is preferable that the leading edges are shaped to centralise the mountable item as it is pushed forward to engage the locking element. In an alternative construction, the socket element is provided with a different shape to match the particular shape of the rack plate to which it is to be used with.

[0039] In some embodiments, the rack plate or mounting frame may include cylindrical upright elements. The rack plate may include the upright elements as protrusions extending from the underside. The socket element may be shaped such that the nose is guided past the upright elements as it slides into position, with a concave edge between the side wing portions and the tongue portion engaging around the upright elements when in correct positioning.

[0040] There may also be provided an adaptor system that allows a rack plate to be mounted to mounting points on a moveable object. In such an embodiment, mounts may be attached to the underside of the rack plate, with the mounts adapted to rotate and slide with respect to the rack plate to position downwardly extending mounting pegs to align with the mounting points on the moveable object. The pegs may comprise a mounting bolt and one or more annular mount spacers, or be made from one or more peg segments, to provide the desired height between the rack plate and the mounting points.

[0041] According to an aspect of the invention, there is provided a rack plate adapter system to enable a rack plate to be attached to mounting points on a moveable object, the adapter system including: two or more adapter assemblies, each having: one or more pivotable mounts with openings to attach the mounts to a rack plate, via a fastener, in a pivotable manner; a mounting post and a fastener for securing the mounting post to the mounting points on the moveable object.

[0042] In a preferred embodiment, the mounting post is constructed from segments that can be joined together to form a mounting post of the desired height for the particular application. The pivotable mount openings may be slots to allow the adjustment of the position of the posts relative to the rack plate attachment fastener location. In a preferred embodiment, nut sliders may be provided that slide around the mount, with rack plate attachment fastener projecting through the upper side of the nut slide, through the slot, and then into the lower side of the nut slider.

[0043] Additionally, as the angle of mounting points on the moveable object may not correspond to the desired angle of the rack plate, the adaptor system may include alignment wedge components, which can be placed between the mounts and the rack plate. Multiple wedge components can be stacked to obtain the desired orientation.

[0044] A fitting template may be provided that is designed for the specific moveable object mounting points and the aperture locations on the rack plate being used.

[0045] In some embodiments, an adapter system may be provided to allow mounting of the rack plate to laterally oriented bolt holes on the moveable object's body. This adapter system may comprise at least two struts spaced apart by a mounting rail. One end of each strut may attach to the respective ends of the mounting rail. The opposite ends of the struts may attach to the moveable object. At least one, preferably at least two, rail mounts may be provided. The rail mounts may frictionally slide onto the mounting rail and be affixed to the rack plate.

[0098] Detailed description

[0099] Figure 1 illustrates an example moveable object, being a motorcycle 10, to which a mountable item, such as a storage container in the form of a plastic box 12 is attached.

[0100] Projecting from the rear frame of the motorcycle 10 is a rack plate mounting frame 14 with a rack plate 16 affixed to it, as shown in Figure 2. The rack plate 16 shown is a standard KTM™ plate. It will be appreciated that this particular rack plate has been used as an example of a popular plate that is commonly purchased and used by motorcycle riders. The present invention can be shaped to be utilised with any existing or future rack plate designs, and the KTM™ plate illustrated is simply an example. The rack plate 16 has a first edge 18 and a second edge 20.

[0101] Figure 3 shows the two key components of the retention system, a socket element 22 and a locking element 24. Both the socket element 22 and the locking element 24 have upper surfaces 22a, 24a, which are flat surfaces that sit against the underneath surface 26 of a storage container 12, as shown in Figures 4 and 5. In this embodiment illustrated, a mounting plate 28 is placed in the floor 30 of the storage container 12. As shown in Figures 6 and 7, the mounting plate 28 preferably extends across the majority of the floor surface. The retention system can be provided as a kit, that the user can attach to any mountable item that they desire. Multiple kits can be purchased so that the user can have a series of mountable items able to be mounted to their moveable object. Alternatively, a user can purchase storage containers already assembled with a retention system. In some embodiments (not illustrated) the retention system is integrally formed as part of the mountable item.

[0102] In the embodiment illustrated in Figures 4 to 8, pre-drilled threaded holes 32 are provided in the mounting plate. For an existing storage container, the user is required to drill holes through the floor of the container that match the holes provided in the mounting plate. Screws are provided to be inserted into predrilled holes 34 in the socket element 22 and the locking element 24, through the floor 30 of the storage container 12 and into the threaded holes 32 in the mounting plate. This places the socket element 22 and the locking element 24 in the correct spaced location to engage with the rack plate 16 for which that retention system has been designed to work with. There is the option for a rack plate to be purchased as part of the kit.

[0103] Whilst the illustrated embodiment shows the socket element 22 and the locking element 24 as being separate components, it is envisaged that the components could be modified to be provided as a single component. It is also envisaged that the mounting plate could also be integral with the socket element and locking element, with the mounting plate being attached to the outer surface of a storage container in non-illustrated embodiments. Further embodiments are illustrated in later Figures.

[0104] Turning back to the embodiment of Figure 3, the socket element 22 has a central portion 36, a central tongue portion 38, two side wing portions 40 and a rear wall 42. The areas forward of the rear wall 42 create a recessed socket area 44. The rear wall 42 is generally shaped to match the first edge 18 of the rack plate, as best illustrated in Figure 12. The tongue portion 38 has a ramped leading edge 45 to guide the socket element 22 underneath the first edge 18 of the rack plate. The two side wing portions 40 also have ramped leading edges 46. An additional hole 48 is provided in the central portion 36, which can be used to semi-permanently attach the storage box to the rack plate by means of a retaining bolt if a more secure connection is needed for theft prevention or off-road riding. When attached to the storage container, as shown in Figure 6, a socket 50 is created between the recessed socket area 44 and the underneath surface 26 of the storage container.

[0105] The locking element 24 has a rear face 52 that is generally shaped to correspond to the second edge 20 of the rack plate, as best illustrated in Figure 12. The width of the locking element 24 is sized to fit between the frame elements of the particular rack plate and motorcycle design. However, it will be appreciated that the locking element and socket elements may have alternative sizes and shapes to those illustrated and alternative designs are shown in later Figures. As best seen in side view in Figure 5, the lower surface 54 of the locking element 24 is angled to assist in it moving over the second edge 20 of the rack plate as it drops into the engaged position. The engaged position is shown in Figures 8 through 12.

[0106] Figure 6 includes arrow 'A', which indicates the direction of travel of the motorcycle. This also indicates the forward direction of the storage box when being installed. Best illustrated in Figures 8 and 9, the retention system starts in a disengaged position, whereby the socket element 22 and locking element 24 are located behind the first, or trailing, edge 18 of the rack plate 16, as shown in Figure 9a. As the storage container to which they are attached is moved in the direction of arrows 'A', as shown in Figure 9b, the locking element 24 moves over the top surface 56 of the rack plate, with the ramped leading edge 45 of the tongue portion of the socket element sliding underneath the bottom surface 58 of the first edge 18 of the rack plate. Once the locking element 24 slides beyond the second edge 20 of the rack plate it drops down to prevent further sliding movement.

[0107] In this engaged position shown in Figure 9c, the rear wall 42 abuts the first edge 18 and the rear of the rack plate is retained within the socket created between the recessed socket area 44 and the bottom surface of the storage container, as shown in Figures 10 and 11.

[0108] The socket element 22 prevents the mountable item from being directly lifted away from the rack plate. The locking element 24 prevents the mountable item from being slid in either direction. The end of the mountable item with the locking element must first be lifted or moved away from the rack plate before the item can be slid to disengage the rack plate. The positive engagement enables the retention without additional locking, such that the moveable object, such as a motorcycle or other vehicle, can be in motion without the mountable object moving during travel.

[0109] To further secure the engaged position, a lock pin 58 is inserted into a passage provided in the back face of the locking element (see also Figure 8). At the inner end of the passage there is provided a magnet, which holds the lock pin 58 in place during transport. An additional padlock arrangement could be provided to enable a more secure connection against theft. However, the removability of the storage container is the intention behind the invention, which allows the storage container to be removed from the motorcycle and taken with the user. For example, it may be removed and taken into a grocery store, where it is filled with the purchased goods and carried back out to be quickly and easily reinstalled on the back of the motorcycle, removing the need for plastic shopping bags.

[0110] To disengage the storage container, the lock pin 58 is pulled out against the attraction of the magnet. The front of the storage container is lifted until the bottom of the locking element clears the second edge and can slide backwards over the rack plate. The backwards movement disengages the rear wall 42 from the first edge and the socket element slides off the rear of the rack plate, ceasing to retain the rack plate in the socket. The lock pin 58 may be reinserted into the passage for safe keeping. The socket element 22 and locking element 24 may be made from any suitable materials, for example a 3D printed laminate. These parts may be reinforced with steel plates 62 on their lower surfaces.

[0111] In the case of the bike falling on its side, it is desirable for the retention system to fail to prevent high forces damaging the bike, rack plate or frame. In this case the strength of the socket element and locking element can be tuned to fail at a level of side loading that does not exceed the point where the rack plate or its mounts are damaged.

[0112] In the case of a front end impact, it is desirable for the storage container to remain firmly attached to the rack plate. This can be ensured by the addition of reinforcing plate 62 extending across the socket element and locking element. Preferably, these plates would be retained by the plate mounting screws to create metal to metal connection points.

[0113] Alternative embodiments of the retention system and kit are shown in Figures 13 through 21. Similar components to the above described embodiment have been given the same reference numbers with the prefix '1' or '2', and will not be described again.

[0114] Figures 13 and 14 show an alternative socket element 122, which has a pointed central tongue portion 138 with two side wing portions 140. The leading edge 146 running along the central tongue portion and side wing portions has a fillet or radiused top edge. Concave edge areas 141 are created between the tongue portion and the side wings. The curved edge together with the curved profile of the point of the tongue portion and the concave edge areas, makes the socket element self-align as it is slid onto the rack plate, even if the angle of entry is not fully aligned to begin with.

[0115] The underside of the socket element, as shown in Figure 14, includes a recessed slot 161 to receive a reinforcing steel plate (not shown, but similar to plate 62 in the previous embodiment). Figure 15 shows a universal rack plate 116 that can be mounted to an existing rack plate mounting frame 114. The existing rack plate may be removed, and the universal rack plate 116 mounted in its place. As shown in Figure 16, the existing frame mounting points could be used, with the universal rack plate 116 pre-drilled with pilot holes for a number of different types of existing rack plate mounting frames.

[0116] An alternative, not shown embodiment, would be to mount the universal rack plate 116 on top of the existing rack plate, which would remain in position. To do this, a spacer or spacers would need to be provided that elevates the universal rack plate above the existing rack plate in order to provide a clearance gap in between to accommodate the sliding of the socket element and dropping down of the locking element.

[0117] Another alternative embodiment of the universal rack plate 216 is shown in Figure 17. The main difference is the shape of the front of the plate, which has a generally rectangular outer shape. This provides a greater surface area that allows a cut-out portion 219 that includes the second edge 220 for engagement by the locking element. The first edge 218 is of generally similar pointed outer shape. A number of pilot holes 221 can be seen in the surface of the rack plate 216, which allows it to be adapted for use with a variety of existing mounting frames. The peripheral cut-out slots 223 reduce the weight of the rack plate, but also provide additional mounting points, should the user wish to the rack plate 216 with a bag that doesn't have the retention system and they opt to tie down their bag.

[0118] The universal rack plate 216 can also be adapted for post mounted rack systems, whereby a mounting frame includes two upright vertical tubes into which an L-shape tubular frame rack is typically mounted. One such example is the Ventura™ rack, which is connected to the mounting system via upright vertical tubes. If this rack and mounting system is currently in use on a motorcycle, the tubular frame rack section can be removed and the universal rack plate 216, as shown in Figure 18, installed in its place. With this variation, downwardly protruding pegs 270 are provided as threaded cylinders retained by countersunk screws 274. The pegs 270 are inserted into the open ends of the mounting systems upright vertical tubes 272, as shown in Figure 19.

[0119] Figures 20 and 21 show the universal rack plate embodiment of Figure 18 with the retaining system, including the socket element of Figures 13 and 14. Another feature of the universal rack plate is the addition of downward protrusions 276 located towards the first edge. As with the other embodiments, when the socket element 222 and locking element 224 are attached to the mounting plate 228, a socket is created that slides over the first edge 218. As the socket element 222 is moved forward, the curved from edge, if misaligned, contacts the protrusions 276 and guides the socket element into central alignment. The concave edge areas 241 then engage around the protrusions 276 as the rear wall 242 abuts against the first edge 218. In this position, the locking element 224 will have cleared the second edge 220 and dropped into the cut-out portion 219. With the second edge 220 being part of an internal cut-out portion rather than the leading outer edge, the locking element 224 is enclosed on more than one side, making for a more secure connection. Tolerancing is done to ensure that the locking element slides into the cut-out without difficulty and enables removal without too much lifting effort required.

[0120] Another advantage of the cut-out portion 219 is that the lock pin (not shown) can be inserted fully through an open passage 259 in the locking element 224 and be supported on both sides of the locking element under the rack plate.

[0121] An added bonus of these particular embodiments is the inclusion of a cup holder cut-out 278 in the centre of the rack plate 216 to enable you to hold your coffee cup when you return from the shops with a loaded container before loading the container onto the retention system.

[0122] Further alternative embodiments are shown in Figures 22 through 48. Similar components to the above described embodiment have been given the same reference numbers with the prefix '3', '4', '5' or '6', and will not be described again. Figures 22 to 24 show an alternative retention system that includes socket element 322 and locking element 324, connected by mounting plate 328. The main difference between this embodiment and earlier described embodiments, is that the mounting plate 328 is intended to be attached to the outer surface of the mountable item.

[0123] Further differences include the shape of the components. The socket element 322 has a central portion 336 and a rear wall 342. Rather than the outer surface 343 following the inner surface 347 of the rear wall it creates a straight edge. The inner surface 347 of the rear wall is still shaped to match the first edge of the rack plate to which it will be installed on. The areas forward of the rear wall 342 create a recessed socket area 344, with two tongue portions 338a, 338b. Each of the tongue portions have a ramped leading edge to guide the socket element underneath the first edge 318 of the rack plate. The socket area 344 is created between the socket element 322 and the mounting plate 328 in this embodiment.

[0124] The locking element 324 may be created in two parts, the first part 324a creating the channel 359, with the second part 324b serving to close the channel 359. The advantage of making the locking element 324 in two parts is that the first part 324a can have angled outer side walls, which increase the ease of insertion of the locking element 324 into the cut-out portion 319 once it passes the second edge 320.

[0125] Figures 25 to 26 show the retention system mounted to a mountable item, such as storage container 312. The mounting plate 328 sits flush against the undersurface 326, with screws passing through from the inside of the storage container.

[0126] Figures 27 and 28 show yet another embodiment, the main difference of this embodiment being that the socket element 422 has been able to be reduced to its essential elements. As shown in Figures 29a and 29b, the socket element 422 has a central portion 436, with a shorter sloped tongue portion 438. Truncated rear wall portions 442a, 442b create socket area 444. Steel plate 462 reinforces the central portion 436 where the greatest upward pressure would be applied should the rear of the container be lifted. Figure 30 shows how base mounts 464 can be attached to the socket element 422 and locking element 424 with profiled surfaces customised to match the non-flat undersurface of heavy duty storage containers, for example. The undersurface of such containers often has hexagonal or honeycomb ridge patterns. The base mounts 464 can be customised to fit different brand's containers.

[0127] The secure nature of the retention system allows it to be mounted in a vertical orientation. Such a system is shown in Figures 31a and 31b. A rack plate 416 can be secured to a motorcycle pannier, or side case, frame 466. A socket element and locking element can be attached to the surface of the sidecase 468. The socket element slides over the rack plate 416 to engage first edge 418, with the locking element being forced to move sideways into opening 419 once it clears second edge 420.

[0128] Figures 32 and 34 show a rack adaptor assembly that can enable a rack plate to be attached to any object that has mounting points that accept standard bolts. Mounts 380 in the form of oval shaped plates are attached to the underside of the rack plate 316. The mount plates 380 have a slot 382 that allows a bolt 384 to attach the mount plates 380 to the rack plate 316. The slot 382 allows the mount plate 380 to be slid along the slot and rotated with respect to the bolt 384 before the nut 386 is tightened. Downwardly extending mounting pegs 388 are positioned towards one end of the mount plates 380, which can be inserted into the mounting points on the object to which the rack plate is to be affixed. By providing the slots 382, the mounting pegs can be positioned to maximise the number of different objects the rack plate can be attached to, as illustrated in the different positions in Figures 32 and 33. In one embodiment, the pegs 388 may comprise a mounting bolt 388a and an annular mount spacer 388b, with different heights being used to obtain the desired height of the rack plate from the object mounting points. Several mount spacers may be stacked on top of each other.

[0129] The mounting points on an object may lie at an angle other than horizontal, whilst there may be a desire for the rack plate to be positioned horizontal or at a different incline. Alignment wedges 390 can be inserted between the rack plate undersurface and the mount plates 380. The nature of the slots 382 means that bolts 384 can still obtain a solid connection, which can be enhanced by using a spherical nut 386a, as shown in Figure 36. Figures 34 to 35 show circular discs 392 as examples of mounting points of an object for context. Wedges of different angles can be provided in sets and can be stacked to make the desired angles.

[0130] An alternative rack adapter assembly is shown in Figures 37a to 38. Mount plates 480 are oval shaped plates with a slot 482 that allows fastener 484 (not shown) to attach the mount plates 480 to the rack plate 416. A nut slider 485 with a threaded passage 486 is provided in this embodiment to make sliding and tightening of the fastener in position easier. Downwardly extending pegs 488 are positioned towards the end of the mount plates opposite the slot 482. The pegs 488 are made up of peg segments 488a, 488b, 488c, 488d, with opposing ends having mouths and tongues to allow them to slot into each other to form a column. A bolt 488E (visible in Figure 38) passes through the centre of the peg segments to engage with the object to which the rack plate is to be mounted. Touring and adventure motorcycles usually have two pairs of vertically oriented rack mounting holes. For these, a set of four mount plates 480 can be used, as shown in Figure 38.

[0131] Some motorcycles have a single pair of vertically oriented rack mounting holes. In these cases, a pair of wider, stiffer mount plates 480 can be used to create a double rack adaptor assembly mount, as shown in Figure 39. Each mount 480 includes a nut slider 485 with fastener 484, the head of which sits on the other side of the rack plate to join the mounts to the rack plate.

[0132] Some motorcycles have laterally oriented bolt holes on the side of their body. A side mount rack adapter assembly is shown in Figures 40 and 41. The assembly includes a pair of mounting struts 481, which attach to the body bolt holes. A mounting rail 483 extends across the body between the two mounting struts 481. Rail mounts 487 are provided having a body with a flat upper surface 489, a slotted opening 491 and a lateral passage 493 extending through. The rail mounts 487 slide onto the mounting rail 483 with the passage 493 creating a tight friction fit. Two rail mounts 487 are spaced apart on the mounting rail 483 and a rack plate 416 is attached to the rail mounts 487 via a bolt projecting through the slotted opening 491. The angle of the flat upper surface 489 can be adjusted by rotating on the mounting rail 483. The system allows for adjustment in angle and location to fit to different motorcycle bodies and rack plates. Figure 40 shows a single side mount rack adapter assembly in use. As shown in Figure 41, two assemblies could be used if there are four laterally oriented bolt holes on the motorcycle body.

[0133] Another embodiment of a rack plate 516 is shown in Figures 42 to 45, which incorporates a lock assembly, which includes a lockpiece 558, that works in a similar way to lockpiece in the form of lock pin 58 in the first embodiment described. The lockpiece 558 can be engaged to project through the channel 559 in the locking element 524 once it has passed the second edge 520 and displaced into the cut-out portion 519.

[0134] The lockpiece 558 is attached to a shuttle 513, as shown in Figure 43. The lockpiece 558 and shuttle 513 run along a channel 515 in a lock housing 517 attached to the underside of the rack plate 516. The end of the lockpiece 558 is held within the channel 515 and kept in alignment by a housing plate 593. A locking wedge 521 is attached to the underside of the rack plate on the other side of the cut-out portion 519. The locking wedge 521 is positioned where the sliding lockpiece 558 emerges from the channel 515 and has a slightly inclined surface, which pushes the end of the lockpiece 558 downwards, thus pulling the mountable item down hard against the rack plate. The locking wedge 521 depth can be adjusted with a grub screw set into the rack plate behind the wedge face.

[0135] Movement of the sliding lockpiece 558 can be actuated by a lock lever 523 that may be positioned to extend from either side of the rack plate. The inner end 525 of the lock lever 523 is attached to the shuttle 513 at a mounting point 527. The shuttle may include two mounting points 527. The lock lever 523 is pivoted off a pin 529 extending down from the rack plate through a mounting hole. The pin 529 may be installed at a different mounting hole, with the lock lever inner end 525 being attached to the other mounting point (as shown in Figures 44 and 45) to suit the needs of the particular rack plate or user preference. The lock lever 523 is shown in the disengaged position in Figure 44, whereby the cut-out portion 519 and second edge 520 are clear. When the retention system is engaged on the rack plate, as shown in Figure 45, the socket element 522 engages the first edge 518 and the locking element 524 passes the second edge 520 and drops into the cut-out portion 519. The user then slides the lock lever 523, whereby it pivots about pin 529 forcing the shuttle 513 and lockpiece 558 to slide along the channel 515 and project through the channel 559 engaging the locking element 524. An aperture 531 may be provided in the end of the lockpiece 558 whereby a padlock can be used to prevent disengagement of the lockpiece.

[0136] The lock assembly can be used as a helmet lock when not in use. For helmets with a pair of D loops, the lockpiece 558 can pass through one or both of the D loops and the lever then pulled to the closed position. The closed position can then be locked to prevent removal. For other helmets, the chin strap or other loop may be used.

[0137] Figure 38 shows a rack plate with lock assembly according to another embodiment, which functions very similarly to the embodiment of Figures 42 to 45. It is shown in the locked position, but without the locking element or socket element. The main differences being that the lockpiece 458 does not include a shuttle. The mounting points 427 project directly from the lockpiece 458. Additionally, the pivot pin 429 is and lock lever 423 are contained within a guide housing 457 that has slotted openings on either side to constrain the movement of the lock lever 423.

[0138] The present invention has application to be mounted to other moving vehicles, such as a bicycle. Figures 46 and 47 show a retention system designed for use with a bicycle. The system utilises the same socket element 622 and locking element 624 as shown in Figures 27 to 29b. However, the rack plate 616 is smaller, in particular, narrower. The socket element 622 fits over a first edge (not visible) and the locking element slots into opening 619 once it passes second edge. A locking assembly is incorporated into the underside of the rack plate, with the lock lever 623 taking a different form in order to keep the rack plate depth narrow. The lock lever 623 is of a triangular shape, which allows the pivot pin 629 to sit adjacent to the edge of the rack plate 616. The inner corner of the triangular lock lever 623 is connected to the mounting points 627 to slide the lockpiece 658 along the channel 615 of the lock housing 617. The outer corner of the lock lever 623 contains a handle 623A that can be actuated by pulling outwards to disengage and pushed inwards to engage, with the lock lever 623 pivoting about pivot 629. In this embodiment, the lock lever 623 sits between the rack plate and the lockpiece 658. The guide housing 657 is integrated into the lock housing 617. A wedge 649 is provided on the upper surface of the lock lever 623, as shown in Figures 48 and 49. The wedge 649 is angled to slide under the edge of the rack plate 616, deflecting the lock lever until it rests in a depression or slot 649A in the rack plate, as shown in Figure 49. The lock lever 623 is deflected downwardly as it is pulled outwards to disengage the wedge 649 from the slot 649A.

[0139] To attach the rack plate to a bicycle rack or to an industry standard pannier frame, zip mounts 633 are provided. The zip mount is shown in Figure 50, which has a central body 635, with a curved cutout 637 on the base to rest on standard pack rack rails. Protrusion 639 friction fits into openings 641 on the rack plate. A screw 639A is then inserted into the top (see Figure 51). The openings 641 are shown in Figure 46, with the zip mounts 633 in position in Figure 47. The openings 641 are provided as slots in order for the position to be adjusted for slightly differently spaced rack rails.

[0140] Passages 635A are provided through the body 635. As shown in Figure 51, once the zip mounts 633 are positioned onto a tubular member of a frame zip ties 637A can be passed through the passages 635A and around the tubular member to secure the rack plate to the bicycle rack frame. Tightening the mounting screws 639A causes the zip ties 637A to protrude from the base of the zip mount and bear against the tubular member, thus pushing the rack plate upwards, further tightening the zip ties. The present invention provides a robust and secure connection between the mountable item and the rack plate, by engaging and sandwiching sections of the rack plate between components of the retention system and mountable item, whist providing a quick and easy release. The invention provides ways to mount the rack plate to various objects, providing versatility.
