A MODULAR SYSTEM FOR A VEHICLE TECHNICAL FIELD

[0001] The present invention relates to a module system for a vehicle. More particularly, the present invention relates to a frame for attachment to the chassis of a vehicle. Even more particularly, the present invention relates to a system and frame for connecting a module to a vehicle.

BACKGROUND ART

[0002] Cab chassis vehicles are typically bought by tradespeople who then customise the vehicle with a tray or canopy that suits their needs. Unfortunately, the tray or canopy may be permanently fitted to the vehicle or may be difficult or expensive to remove. This means that once the tray or canopy is fitted, the vehicle's usability becomes less flexible.

[0003] Some attempts have been made to overcome these problems. For instance, some lift off canopies are available which use legs associated with jacks or pivotally mounted to the exterior of the canopy to raise or lower the canopy onto an existing tray or tub of a vehicle. However this arrangement suffers from a number of disadvantages, such as requiring precise lowering of the canopy onto the vehicle so that the connection points are aligned. Further, raising and lowering of a canopy onto an existing tray or tub of a vehicle may damage a surface of the tray or tub. This may leave unsightly marks or make the tray or tub susceptible to rusting.

[0004] Thus, there would be an advantage if it were possible to provide an improved system and frame for connecting a module to a vehicle that ameliorates the aforementioned problems

[0005] It will be clearly understood that, if a prior art publication is referred to herein, this reference does not constitute an admission that the publication forms part of the common general knowledge in the art in Australia or in any other country.

SUMMARY OF INVENTION

[0006] The present invention is directed to a frame for attachment to the chassis of a vehicle and a system for connecting a module to a vehicle, which may at least partially overcome at least one of the abovementioned disadvantages or provide the consumer with a useful or commercial choice.

[0007] With the foregoing in view, the present invention in one form, resides broadly in a frame for attachment to the chassis of a vehicle, the frame comprising one or more attachment portions adapted to facilitate attachment of the frame to the chassis, the frame further comprising one or more connection portions adapted to connect the frame to a removable module.

[0008] The frame may be of any suitable size, shape, or configuration. Preferably, the frame is of sufficient size and mechanical properties (strength, rigidity, shape, etc.) to support the weight of a load carried over the chassis of a vehicle under static and dynamic conditions. However it will be understood, that the size, shape and configuration of the frame may vary depending on a number of factors, such as the type of vehicle to which it is attached, the centre of gravity of the vehicle, the owner of the vehicle's personal preferences, or the type of accessories attached to the frame.

[0009] The size and shape of the frame may vary depending on the type of vehicle to which it is attached, although it is envisaged that in use, the frame does not extend beyond the overall width of the body of the vehicle or beyond the maximum recommended rear overhang for the vehicle. In an embodiment of the invention, a first end of the frame may abut or be in close proximity to the cab of the vehicle and an opposed second end of the frame may be in proximity of the maximum recommended rear overhang for the vehicle. In an alternative embodiment of the invention, a first end of the frame may abut or be in close proximity to the cab of the vehicle and an opposed second end of the frame may be in proximity to a point located between the rear axle of the vehicle and the maximum recommended rear overhang for the vehicle.

[0010] The frame may be adapted for attachment to the chassis of a vehicle. Any suitable vehicle may be used, for instance a chassis cab, a half truck, a cutaway van chassis, a chassis cab truck, or the like. It will be understood that a chassis cab or van chassis is a vehicle where the rear chassis is left bare for the customer to install any suitable vehicle body.

[0011] In an embodiment of the invention, the frame may be mounted directly on the chassis of the vehicle. Optionally, a compressible material may be placed between the chassis and the frame before the frame is mounted on the chassis of the vehicle. Alternatively, a compressible material may be placed between an attachment bolt and a surface of the chassis and/or the frame before the frame is mounted on the chassis of the vehicle.

[0012] In an alternative embodiment of the invention, one or more attachment portions may be used to attach the frame to the chassis. Any suitable attachment portions may be used. Preferably, however, the one or more attachment portions may be adapted to facilitate attachment of the frame to the chassis of the vehicle. For instance, the attachment portion may be a flexible mount (such as spring mounts, spring loaded bolts), a fixed mount (such as mounting brackets, angled steel mounts), a support member (such as C-channel beams, universal beams, cross rails), or combinations thereof. In other embodiments of the invention, the frame may be provided with one or more apertures therein that are adapted to align with one or more apertures in the chassis. In this way, a mechanical fastener (such as a bolt or the like) may be passed through the aligned apertures in order to secure the frame to the chassis. However, it will be understood, that the type of attachment portion may vary depending on a number of factors, such as the configuration and attachment points of the frame and chassis, the type of load it is carrying and the owner of the vehicle's personal preferences.

[0013] In an embodiment of the invention the attachment portions are attached to a surface of the frame. Preferably, the attachment portions are attached to a lower surface of the frame.

[0014] The attachment portions may be attached to the chassis by any suitable means. It is envisaged that in use, one or more bolts, including U-bolts, structural bolts (such as high tensile bolts) and the like, may be used to attach the frame to the chassis. Optionally, a locking device may be fitted to the mechanical faster. For instance, a suitable locking device may be a lockwire or split pin.

[0015] The frame may comprise two or more support members. Preferably, the two or more support members are substantially parallel to one another. In an embodiment of the invention, the two or more support members are spaced apart. Preferably, the two or more support members are spaced equally on either side of a centre line of the frame. In an embodiment of the invention, a first support member may be located towards a first side of the frame and a second support member may be located towards an opposing second side of the frame. It will be understood that the opposed sides of the frame may be oriented at any suitable angle to the longitudinal axis of the chassis. For instance, the opposed sides of the frame may extend substantially parallel to the longitudinal axis of the chassis. Alternatively, the opposed sides of the frame may extend substantially perpendicular to the longitudinal axis of the chassis.

[0016] The support members may be of any suitable size, shape or configuration. Preferably, the support members are of sufficient length that they extend at least the length between two spaced apart chassis rails of the vehicle. Preferably, the two or more support members extend substantially the length of the frame. Thus, the support members may extend substantially the entire distance between the cab of the vehicle and the rear of the frame.

[0017] In an embodiment of the invention the support members may be connected by one or more cross members, such as one or more cross beams or the like. The cross beams may extend at any suitable angle to the support members. Preferably, the cross beams may extend substantially perpendicular to the support members. In some embodiments of the invention, the cross beams may interconnect opposed ends of the support members such that the frame is substantially square or rectangular in shape.

[0018] The support members and cross beams may be fabricated from any suitable material or combinations of materials. Preferably, the support members and cross beams may be fabricated from a material with relatively high rigidity and strength. For instance, the support members and cross beams may be fabricated from metal, such as, but not limited to, steel (including powder-coated steel, galvanised steel, extruded steel etc), aluminium (including high tensile aluminium alloys, extruded aluminium, etc.). In an embodiment of the invention, the support members or cross beams may be at least partially hollow. In an embodiment of the invention, the support members and cross beams may be C-channel beams. In an embodiment of the invention, the support members and cross beams may be I beams.

[0019] The frame may comprise a floor member. The floor member may be of any suitable size, shape or configuration. Preferably, however the floor member may be a substantially planar surface. The size and shape of the floor member may vary depending on a number of factors, such as the size and shape of the frame or the location and size of any accessories attached to the frame, although it is envisaged that in use, the floor member does not extend beyond the dimensions of the frame. Preferably, however, the floor member is of sufficient size and shape to fit within a space defined by one or more sides of the frame. In a further embodiment of the invention, the floor member may be substantially similar in dimension to the frame.

[0020] The floor member may be fabricated from any suitable material. Preferably, the floor member may be fabricated from a material with relatively high rigidity and relatively low weight. For instance, the floor member may be fabricated from a metal such as aluminium (including high tensile aluminium alloys, extruded aluminium, etc), steel (including powder-coated steel, galvanised steel, extruded steel etc.), or the like. In an embodiment of the invention, the floor member may be formed by providing a metal sheet material. The metal sheet material may have a flat surface, a textured surface, a raised tread plate design or may be perforated. In an embodiment of the invention, the floor member may comprise one or more panels of sheet material. In this instance, it is envisaged that the one or more panels of sheet material may be joined by any suitable technique, such as stitch or spot welding.

[0021] The floor member may be adapted for attachment to the frame by any suitable means. For instance, the floor member may be retained on the frame using one or more mechanical fasteners (screws, bolts, rivets, pins, or the like) or may be welded to the frame using any suitable technique. In an embodiment of the invention, the floor member is attached to one or more support members and/or cross beams.

[0022] As previously mentioned, the frame may comprise accessories attached to the frame. The accessories may be of any suitable type. For instance, the accessories may be storage containers (such as tool boxes, storage boxes, trundle drawers, lockers or tanks), racks or bars, steps and handles, tie rails, mudguards, headboards, or the like. The accessories may be attached to the frame in any suitable location. For instance, a trundle drawer may be affixed to the lower surface of the floor member of the frame while mudguards may be attached to the side of the frame and a headboard may be attached to an end of the frame. In an embodiment of the invention, accessories may be attached to a support member of the frame. In an alternative embodiment of the invention, accessories may be attached to a cross beam of the frame. In a further embodiment of the invention, accessories may be attached to a projection extending outwardly from a side of the frame.

[0023] In an embodiment of the invention, the frame comprises a pair of mudguards positioned outside the periphery of the frame. The mudguards may be adapted for attachment to the frame by any suitable means. For instance, the mudguards may be retained on the frame using one or more mechanical fasteners (screws, bolts, rivets, pins, or the like) or may be welded to the frame using any suitable technique.

[0024] The mudguards may be attached to any suitable portion of the frame. Preferably, the mudguards will be positioned in proximity to an axle or axles of the vehicle. However it will be understood, that the position of the mudguards on the frame may vary on a number of factors, such as the type of vehicle to which it is attached or the owner of the vehicle's personal preferences.

[0025] In a further embodiment of the invention, the frame comprises a pair of mudguards, wherein each mudguard may be attached to a storage box. The storage box may be attached to the mudguard by any suitable means. For instance, the mudguard and the storage box may be integrally formed. Alternatively, the storage box may be attached to the mudguard. For instance, the toolbox may be retained on the mudguard using one or more mechanical fasteners (screws, bolts, rivets, pins, or the like) or may be welded to the frame using any suitable technique. The storage box may be attached to any suitable portion of the frame.

[0026] Preferably, the mudguards and storage boxes may be fabricated from a material with relatively high rigidity and relatively low weight. For instance, the mudguards and storage boxes may be fabricated from aluminium (including high tensile aluminium alloys, extruded aluminium, etc), steel (including powder-coated steel, galvanised steel, extruded steel etc.), or the like. In an embodiment of the invention, the mudguards and storage boxes may be formed by providing a sheet material. The sheet material may have a flat surface, a textured surface, a raised tread plate design or may be perforated.

[0027] The frame may comprise an electrical portion. Any suitable electrical portion may be provided, such as one or more spotlights, electrical outlets, appliances (including winches or the like). In a preferred embodiment of the invention, the electrical assembly may include a tail light assembly. Any suitable tail light assembly may be used. Preferably, the tail light assembly of the frame and the lower part of the rear wall of a module have a complementary shape. It is envisaged that, in use, the contours and shape of the tail light assembly of the frame and the lower part of the rear wall of a module are similar such that it provides an almost seamless transition between the module and the frame.

[0028] The frame may be connected to a removable module. It will be understood that the phrase "removable module" refers to the ability to remove a module from the frame with relative ease (i.e. non-destructively and without complicated or time consuming process), and to readily connect the module, or a different module, to the frame. Any suitable module may be used. For instance, the module may be a tray, a tub, a container or box body, a canopy, a service body, a bus-style body, a caravan-style body, a camper, or a motor home.

[0029] The frame may comprise one or more connection portions adapted to connect the frame to a removable module. The connection portions may be of any suitable size, shape, or configuration. Preferably, however the connection portions are of sufficient size and mechanical properties (strength, rigidity, shape, etc.) to retain a module on the frame and to facilitate movement of the module relative to the frame. In an embodiment of the invention, the frame and the module are each provided with connection portions, wherein the connection portions facilitate the movement of the module relative to the frame. For instance, the connection portions attached may be slidably engaged with each other. In an embodiment of the invention, the connection portion attached to the module may be mounted for sliding motion longitudinally along the connection portion attached to the frame.

[0030] Preferably, the connection portions are provided with complementary engagement portions that facilitate the engagement of a first connection portion attached to the frame and a second connection portion attached to the module. In an embodiment of the invention, more than one type of complementary engagement portions may be provided. The complementary engagement portions may be of any suitable form. For instance, the engagement portions may comprise shapes capable of cooperating, such as a tongue and groove-type system, surfaces that are provided with sliding contact surfaces for low-friction engagement, or combinations thereof. In an embodiment of the invention, at least a portion of the connection portion is provided with a cooperating shape, wherein the cooperating shape substantially precludes lateral movement of the module relative to the frame. In an embodiment of the invention, at least a portion of an upper surface of the connection portion is provided with a sliding contact surface, wherein the sliding contact surface is in low friction engagement with an opposing connection portion.

[0031] The connection portions may be of any suitable length. Preferably, the connection portions are of sufficient length that they extend substantially the length of the frame. The connection portions may be a unitary structure. Alternatively, the connection portions may be a composite structure, comprising two or more connection portions that have been connected together. In an embodiment of the invention, the connection portions may be an elongate member. In a most preferred embodiment of the invention, the connection portions comprise elongate extruded sections.

[0032] The connection portions may be fabricated from any suitable material or combinations of material. Preferably, the connection portions may be fabricated from a material with relatively high durability and resilience. For instance, the connection portions may be fabricated from metal, such as, but not limited to, steel (including powder-coated steel, galvanised steel, extruded steel etc), aluminium (including high tensile aluminium alloys, extruded aluminium, etc.) or a polymeric material such as, but not limited to, nylon, polyamides, polycarbonate, polyethylene, polypropylene, polystyrene, polyvinyl chloride, acrylonitrile butadiene styrene and the like, or any suitable combination thereof.

[0033] The connection portions may be provided with a coating. Preferably, the coating reduces friction between the two connection portions when the module moves relative to the frame. Any suitable low-friction coating may be used. For instance, the coating may be a polymeric material, such as, but not limited to, fluropolymers or a vacuum deposited metal, such as, but not limited to tungsten disulfide, or combinations thereof. In other embodiments of the invention, the abutting surfaces of the connection portions and/or the module may be provided with a lubricating substance thereon. Any suitable lubricating substance may be used, such as, but not limited to, oil, grease or the like.

[0034] In an embodiment of the invention, the connection portions may be mounted to an upper surface of the frame. Preferably, the connection portions may be mounted to an upper surface of the floor member. In an embodiment of the invention, the connection portions may be mounted to opposing sides of the frame. Preferably, the connection portions may be mounted to opposing sides of the floor member. In an embodiment of the invention, the connection portions may be inserted at least partially into a recess located in the upper surface of the frame, wherein the connection portion may be mounted to the frame thereto. Preferably, the connection portions may be inserted at least partially into a recess located in the upper surface of the floor member, wherein the connection portion may be mounted to the floor member thereto. It is envisaged that, in use, at least partially inserting the connection portions into a recess may reduce lateral stresses on the connection portion.

[0035] The connection portions may be mounted to the frame or floor member in any suitable manner. Preferably, the connection portions are mounted such that they are substantially precluded from movement relative to the frame. For instance, the connection portion may be attached to the frame using one or more mechanical fasteners (screws, bolts, rivets, pins, or the like), an adhesive, a heat or chemical treatments, or may be welded to the frame using any suitable technique.

[0036] In an embodiment of the invention, one or more connection portions may be used. In a preferred embodiment of the invention, at least two connection portions may be used. The number of connection portions may vary, depending on a number of factors, such as the type of module to be connected to the frame, the width of the module, or the type of connection portions used. For instance, it is envisaged that for a larger or heavier module, a greater number of connection portions may be required than for a smaller or lighter module.

[0037] The frame and/or the module may be provided with one or more connection enhancement members. The connection enhancement members may be of any suitable form, although it is envisaged that the connection enhancement members may be provided to assist in locating the module in place on the frame. In some embodiments of the invention, the connection enhancement members may include one or more wheels, rollers, casters or the like adapted to improve the ease of movement of the module relative to the frame.

[0038] In some embodiments of the invention, the module may be lowered onto the frame from above. In this embodiment of the invention, it is envisaged that the module may be lifted to a point above the frame and then lowered onto the frame for connection thereto. The module may be lifted using any suitable technique. For instance, the module may be lifted by one or more people, using a block and tackle, using a crane, using adjustable leg members, a forklift, a winch, or the like.

[0039] Alternatively, the module may be lifted to abut or rest on a portion of the frame, and then may be moved relatively to the frame to bring the module into connection with the frame. For instance, the module may slide relative to the frame.

[0040] In an embodiment of the invention, one or more accessories may be attached to the connection portions mounted to the frame. Preferably, the upper surface of the one or more accessories and the complementary engagement portions of the connections portions are substantially horizontal. Preferably, the upper surface of the one or more accessories is at a height below the height of the complementary engagement portions of the connections portions.

[0041] The connection portions may comprise one or more apertures spaced along a surface of each of the connection portions. Preferably, the apertures are located along a vertical surface of each of the connection portions. In an embodiment of the invention, the module may be secured in place relative to the frame by inserting one or more locking members at least partially into one of the apertures in each connection portion. In this way, the module may be substantially precluded from movement relative to the frame. Any suitable locking member may be used, although it is envisaged that the locking member may comprise a mechanical locking member. For instance, the locking member may comprise a mechanical fastener such as lock pins, lynch pins, threaded bolts, tail gate latch, anti luce fasteners and the like.

[0042] In an alternative embodiment of the invention, the module may be secured in place relative to the frame by providing a locking member to the vertical surface of a first connection portion and a catch plate to the vertical surface of the second connection portion, wherein when actuated the locking member pivotally engages the catch plate to close the latch. Any suitable locking member may be used, although it is envisaged that the locking member may comprise an over-centre latch, spring latch, and the like.

[0043] As previously mentioned, the frame may be connected to a removable module. It will be understood that the phrase "removable module" refers to the ability to remove a module from the frame with relative ease (i.e. non-destructively and without complicated or time consuming process), and to readily connect the module, or a different module, to the frame. Any suitable module may be used. For instance, the module may be a tray, a tub, a container or box body, a canopy, a service body, a bus-style body, a caravan-style body, a camper, or a motor home.

[0044] The module may comprise one or more leg members. In a preferred embodiment of the invention, at least a pair of leg members may be provided. The leg members may be attached to any suitable part of the module. In an embodiment of the invention, the leg members may be removably mounted to the module. In an alternative embodiment of the invention, the leg members may be fixedly mounted to the module.

[0045] In an embodiment of the invention, the leg members may be mounted to a side wall of the module so that they may move relative to the side wall of the module. For instance, each of the leg members may be mounted so as to be foldably, hingedly and/or slidably movable relative to the side wall of the module. Most preferably each of the leg members may be pivotally mounted relative to the side wall of the module. In an alternative embodiment of the invention, the legs may be mounted to a side wall of the module so that they may not move relative to the side wall of the module. For instance, at least one leg member may be mounted such that a projection associated with the leg member may be at least partially received in an opening or recess in the side wall of the module. Preferably, the at least one leg member may be mounted such that a projection associated with the leg member may be at least partially received and retained in an opening or recess in the side wall of the module such that the leg member may be substantially precluded from movement relative to the side wall of the module.

[0046] In a further embodiment of the invention, the leg members may be attached to a lower surface of the module. The leg members may be attached to a lower surface of the module with at least one leg member located on either side of a centre line of the module. More preferably, the leg members may be spaced equally on either side of the centre line of the module. Alternatively, the leg members may be located towards the sides of the module such that in use, the leg members are located outside the periphery of the frame.

[0047] In an embodiment of the invention, each of the leg members may be a unitary structure. In a further embodiment of the invention, at least a portion of the leg members may comprise two or more leg member portions connected to one another. Preferably, the first end of the first leg member portion may be adapted to be at least partially received in the bore of the second leg member portion and retained therein. In some embodiments of the invention, a portion of the first leg member portion may be received and retained in the bore of the second leg member portion, while in other embodiments of the invention substantially all of the first leg member portion may be received and retained in the bore of the second leg member portion. In an embodiment of the invention the leg members may comprise two or more leg member portions wherein each of the leg member portions is in frictional engagement. Preferably, the first leg member portion is adjustably engaged with the bore of the second leg member portion, such that the first leg member portion is capable of movement relative to the second leg member portion. The first leg member portion may be adapted for adjustable engagement with the second leg member portion by any suitable means.

[0048] The leg members and leg member portions may be fabricated from any suitable material or combinations of materials. Preferably, the leg members and leg member portions may be fabricated from a material with relatively high rigidity and relatively low weight. For instance, the leg members and leg member portions may be fabricated from metal, such as, but not limited to, steel (including powder-coated steel, galvanised steel, extruded steel etc), aluminium (including high tensile aluminium alloys, extruded aluminium, honeycomb aluminium, etc.). In an embodiment of the invention, the leg members and leg member portions may be at least partially hollow.

[0049] In an embodiment of the invention, the leg members may comprise two or more leg member portions wherein the leg member portions are adapted for telescopic movement relative to one another. It is envisaged that, in use, a first leg member portion may be slidably received in a second leg member portion in a telescoping fashion for raising and lowering of the frame. In an embodiment of the invention, a ratchet mechanism may be provided in a bore of the second leg member portion in order to allow the position of the first leg member portion relative to the second leg member portion to be adjusted. In a preferred embodiment of the invention, a pneumatic or hydraulic device may be provided in the bore of the second leg member portion in order to allow the position of the first leg member portion relative to the second leg member portion to be adjusted.

[0050] Thus, it is envisaged in use, that the first leg member portion may be moved relative to the second leg member portion to adjust the height of the module relative to the height of the frame attached to a vehicle. The length of the leg member may be adjusted when, for example, the module is being removed from, or lowered onto, a frame attached to a vehicle.

[0051] The leg members may be secured to the vehicle when not in use. The leg members may be secured using any suitable technique, although in a preferred embodiment of the invention, the leg members may be received in a recess, opening or chamber located in the module or the frame. In an alternative embodiment, one or more locking members may be used to secure the leg members to a side of the module or the frame. Any suitable locking members may be used. In an embodiment of the invention, a user may be required to manually remove one or more stop members (such as locking pins or the like) from the module or the frame in order to free the leg members from the module or the frame, and then re-connect the stop members to secure the leg members to the module or the frame. In other embodiments of the invention, the locking members may comprise one or more straps, ties, clips, clasps or the like which are adapted to be secured at least partially about the leg members when the leg members are attached to the module or the frame. In this way the leg members may be substantially precluded from movement relative to the module or the frame during, for instance, movement of the vehicle.

[0052] In a second aspect, the invention resides broadly in a system for connecting a module to a vehicle, the system comprising:

a frame adapted for attachment to the chassis of the vehicle, and

the module adapted for removable connection to the frame,

wherein the frame and the module are provided with complementary connection portions adapted to connect the module to the frame.

[0053] Preferably, the frame is the frame of the first aspect of the invention.

[0054] Preferably, the module is the module of the first aspect of the invention.

[0055] Preferably, the connection portions are the connection portions as described in connection with the first aspect of the invention.

[0056] The present invention provides numerous advantages over the prior art. For instance, the present invention enables an owner of a vehicle to change the rear portion of their cab chassis vehicle with relative ease and without the use of expensive equipment. In addition, the present invention provides an advantage over existing solutions as the connection portions allow the owner to slide the module off the frame without damaging the floor member. The present invention also allows the owner to use the frame without a module attached.

[0057] Any of the features described herein can be combined in any combination with any one or more of the other features described herein within the scope of the invention.

[0058] The reference to any prior art in this specification is not, and should not be taken as an acknowledgement or any form of suggestion that the prior art forms part of the common general knowledge.
