The present invention relates to a cargo carrier comprising a base having a trough shape with an interior space for stowing goods to be transported therein and an openable and closable lid hingedly coupled with the base. The present invention further relates to a method for manufacturing such a cargo carrier.
Modern recreational activities involve the usage of bulky equipment. Thus, cargo carriers for transporting goods, such as bulky sports equipment, on a vehicle roof grow in popularity. Furthermore, due to an increasing mobility, recreational activities are carried out more often, resulting in that cargo carriers are even used more frequently and over longer distances.
However, driving a vehicle with a rooftop cargo carrier results in a higher energy consumption compared to driving a vehicle without such a carrier. The higher energy consumption in turn results in a higher environmental pollution, which should be limited. Associated therewith, driving a vehicle with a rooftop cargo carrier also influences driving characteristics, particularly when driving a vehicle with high speed on a highway.
It is an object of the invention to manufacture and to provide an enhanced cargo carrier with less negative influence on driving efficiency, in particular regarding energy consumption, when mounted on a vehicle.
The object is solved in an aspect of the invention by a cargo carrier according to claim 1 and in a further aspect of the invention by a method for manufacturing a cargo carrier according to independent claim 15.
Advantageous further embodiments of the invention are subject of the dependent claims wherein specific further modifications of these embodiments can be gleaned from the following summary, from the detailed description of the embodiments and from the drawings themselves.
The cargo carrier according to the invention can be mountable on a vehicle. Preferably, the cargo carrier can be mountable on a vehicle roof, wherein the cargo carrier is configured as a rooftop cargo carrier.
According to the present invention, an add-on portion is attached to at least one of the base and the lid for enlarging the overall external volume of the cargo carrier. The overall external volume of the cargo carrier corresponds to the space which is taken by the cargo carrier. Thus, the cargo carrier comprises a volumetric add-on portion that can be mounted to at least one of the base and the lid. In other words, the add-on portion can be added to an outer surface of at least one of the base and the lid, wherein the add-on portion extends outwards from the outer surface of the base and/or the lid.
Accordingly, the add-on portion provides a volumetric expansion of the overall volume of the cargo carrier. Hence, the overall external volume of the cargo carrier including the add-portion is greater compared to the overall volume of the cargo carrier not including the add-on portion. Hence, outer dimensions or the outer size of the cargo carrier including the add-portion can be greater compared to outer dimensions or the outer size of the base and the lid without the add-on portion.
As regards the enlargement of the overall external volume of the cargo carrier, the add-on portion can provide an exterior space outside of the base not overlapping with the interior space of the base. Hence, the overall external volume may comprise the interior space having an internal volume and the exterior space having an additional volume. Accordingly, enlarging the overall external volume of the cargo carrier does not change the interior space of the base, wherein the exterior space and the additional volume is externally added to the base and/or the lid of the cargo carrier. The enlargement of the overall volume of the cargo carrier may also provide additional stowage space for goods in the add-on portion.
The add-on portion can be attached to the base or to the lid, wherein the add-on portion comprises at least one add-on part. Besides that, the add-on portion can be attached to both of the base and to the lid, wherein the add-on portion comprises at least two separate add-on parts, at least one of them being attached to the base and at least another one of them being attached to the lid. The at least two add-on parts can be arranged to the cargo carrier in a pivotable manner with respect to each other for opening or closing the lid.
The add-on portion enables the cargo carrier to have a more complex design. The external shape of the cargo carrier can thus be designed following a large variety of external surface shapes. The add-on portion can have a stabilizing effect making the lid or the base more rigid. The add-on portion of the cargo carrier can further have an aerodynamic effect. The aerodynamic effect can be achieved by an aerodynamically designed external shape of the cargo carrier, particularly provided by the add-on portion. Alternatively or additionally to the aerodynamic effect, a flush meeting of the add-on portion with the lid and/or base can be provided by the add-on portion.
The add-on portion can comprise an air displacement body added to the cargo carrier. Such an air displacement body can be provided by a solid body, a hollow body or a body filled with a filling material. Enhancing aerodynamics of the cargo carrier and providing a higher driving efficiency based thereon can thus be provided with such an air displacement body added to the cargo carrier.
The aerodynamic effect of the add-on portion, which may enhance aerodynamics, can be caused by a streamlined surface of the cargo carrier, which may result in less air resistance of the cargo carrier and less air turbulences occurring on the cargo carrier's outer surface. Less air turbulences can particularly occur near the rear of the cargo carrier. Less air resistance and less air turbulences can also result in less drag of the cargo carrier, which in turn can result in less fuel consumption of the vehicle. The aerodynamic effect can alternatively or additionally be caused by a spoiler surface of the cargo carrier, which also may generate less air turbulences resulting in less fuel consumption of the vehicle due to more laminar air flow. The aerodynamic effect particularly occurs when the cargo carrier is in motion.
Accordingly, a beneficial and preferable idea can be seen in reshaping the outer surface of a hingedly coupled base-lid system of a cargo carrier by adding at least one volumetric add-on part as an extra add-on element such that aerodynamics of the entire cargo carrier can be positively influenced. The reshaping with at least one add-on part can comprise a streamlined reshaping of the outer surface of the base-lid system and can alternatively or additionally comprise a front or rear spoiler, reshaping the outer surface of the base-lid system for changing the air flow around the cargo carrier. The front and rear spoiler are both members which may in addition be able to increase the rigidity of the base or the lid contributing to an overall stability of the cargo carrier. Hence, a cargo carrier can be designed and utilized as an active aerodynamic component of a vehicle when mounted thereon. “Active aerodynamic” can be understood as having a positive influence on aerodynamics, driving efficiency and/or driving characteristics.
The add-on portion can comprise a substantially straight or curved transition between the lid and the base following or not following a convex hull enveloping both of the base and the lid. A transition can comprise at least part of an outer surface of the add-on portion that is located between those elements between which the transition is provided. A transition can also comprise a gap that is located between those elements between which the transition is provided. A gap can be located between the add-on portion and one of those elements between which the transition is provided. A transition between the elements can also be configured as a substantially seamless transition, wherein a substantial gap may not be present.
According to a preferable embodiment, the add-on portion at least partially extends outside of a convex hull enveloping both of the base and the lid. The convex hull can comprise an outer enveloping surface of the base and lid. In other words, the convex hull can be spanned over the outer geometry of the base and the lid, wherein outer edges and corners of the base and lid are connected with each other rectilinearly, such that concave surface regions are non-existent on the enveloping surface. The convex hull of the base and lid can thus comprise plane patches forming a convex enveloping surface. The at least partially extension outside of such a convex hull, provided by the add-on portion, can have the positive effect of providing and manufacturing a wide scope of aerodynamic designs for different design layouts of different base-lid systems of cargo carriers. Manufacturing of the cargo carrier thus allows an efficient optimization of its aerodynamic layout.
According to a further preferable embodiment, the interior space is accessible through an upper opening defined by a rim portion of the base. Furthermore, the openable and closable lid can be adapted to be positioned in a closed state of the lid with an edge portion of the lid contacting the rim portion, in particular contacting an outer surface of the rim portion. In the closed state of the lid, the edge portion of the lid can contact or rest on an outer surface of the rim portion of the base. Accordingly, a step from the edge portion of the lid to the rim portion of the base can be present, wherein the step can occur from an outer surface of the edge portion to an outer surface of the rim portion. Regarding the add-on portion, it can comprise a bridging portion attached to the base or to the lid and can be formed to provide a transition between the edge portion of the lid, preferably an outer surface of the edge portion of the lid, and the rim portion of the base when the lid is in its closed state.
Preferably, the transition can follow the convex hull of the base and lid or can be at least partially located outside of the convex hull. Manufacturing such a geometric bridging of the base and lid can have the positive effect that a step, a recess or a groove on the outer surface of the base and lid can be reshaped or bridged by the add-on portion comprising the bridging portion. Such a reshaping or bridging in turn can provide a substantially streamlined outer surface of the cargo carrier.
The add-on portion can provide a substantially flush transition between the base and the lid of the cargo carrier. According to a further preferable embodiment, the bridging portion provides a substantially flush transition between an outer surface of the bridging portion and the outer surface of the lid and/or between the outer surface of the bridging portion and the outer surface of the base, preferably a lower outer surface of the base, when the lid is in the closed state. A substantially flush transition can comprise a transition being substantially flush within respective manufacturing tolerances for manufacturing a flush transition. Such a substantially flush transition can be provided between the outer surface of the bridging portion and the outer surface of the edge portion of the lid and/or between the outer surface of the bridging portion and the outer surface of the rim portion of the base. Providing such a substantially flush transition can further enhance an efficient streamlined design of the cargo carrier.
According to a further preferable embodiment, the rim portion of the base comprises a U-shape, wherein in the rim portion a wall portion of a side wall of the base is curved outward and over onto itself such that an edge portion of the side wall protrudes downwards, and wherein a gap is formed between the downwardly protruding edge portion and a portion of the side wall of the base. The gap can be traversed, covered or filled with the bridging portion of the add-on portion. The bridging portion can thus provide an air displacement body at least filling a recess within the U-shaped rim portion of the base.
Furthermore, the gap can provide an accommodation space for attaching the bridging portion to the base. According to a further preferable embodiment, an upper edge portion of the bridging portion is accommodated in the gap. The upper edge portion is preferably supported against wall portions defining the gap. Moreover, the upper edge portion can be supported, preferably double-supported, against opposite surface portions of wall portions facing towards an interior space of the gap. In other words, the upper edge portion of the bridging portion can be braced in the gap. Such an accommodation can be provided with a snap-fit assembly for attaching the bridging portion to the base when manufacturing the cargo carrier.
Preferably, in a closed state of the cargo carrier, a bottom edge of the lid can be accommodated in a recess formed in the bridging portion adjacent to the upper edge portion. Thus, a substantially flush transition between an outer surface of the bridging portion and an upper outer surface of the lid can be efficiently manufactured.
According to a further preferable embodiment, the upper edge portion of the bridging portion comprises two supporting sections being supported oppositely against the wall portions defining the gap, preferably with a first supporting section contacting a lower end portion of the edge portion of the side wall and a second supporting section contacting an opposite upper portion of the side wall of the base. Both supporting sections can be arranged in a staggered manner within the gap. The arrangement in the staggered manner can comprise a step-like arrangement of the support sections. Further, both supporting sections can be connected with an intermediate section, wherein the intermediate section is not in contact with the wall portions defining the gap.
According to a further preferable embodiment, the upper edge portion of the bridging portion is double-curved, preferably comprising a zig-zag shape. The upper edge portion of the bridging portion can comprise a Z-shape. Alternatively, the bridging portion can comprise an S-shape. The bridging portion can thus be double-bent when manufactured. Such a shape of the upper edge portion can provide an efficient bracing of the bridging portion within a gap or a groove of the base.
According to a further preferable embodiment, the upper edge portion of the bridging portion is bonded to the wall portions defining the gap, preferably by gluing. With the double-curved shape, the bridging portion can distribute an adhesive provided on the wall portions for bonding the bridging portion evenly between the supporting sections and the wall portions when sliding or snapping in the upper edge portion of the bridging portion into the gap during manufacturing the cargo carrier. Such a bonding of the bridging portion can provide a secure attachment of the bridging portion to the base of the cargo carrier.
According to an embodiment, the bridging portion can be configured as a frame surrounding the base and/or the lid. The frame can be arranged to the base and/or the lid in a substantially horizontal expansion. The frame can be attached to the gap, which can be a circumferential gap. The frame can comprise one or multiple frame parts. The frame can be integrally formed. In other words, the frame can be manufactured in one piece. Alternatively, the frame can comprise at least two bridging parts connected with each other forming the frame. Besides that, the frame can be interrupted comprising at least one bridging parts.
At least one handle and/or at least one lock part can be arranged to the base or lid of the cargo carrier one-sided or two-sided, wherein the lid can be openable on one side or on two sides. According to a further preferable embodiment, the bridging portion comprises a frame horizontally surrounding the base or the lid, wherein the frame preferably comprising at least one hole for a handle and/or a lock part of the cargo carrier. The add-on portion can thus be designed as a horizontally surrounding bridging part providing access to at least one handle and/or lock part. The add-on portion can further be designed as a circumferential spoiler frame horizontally surrounding the cargo carrier. This reduces the flexibility of the element to which it is added, for example the base, and may contribute to the prevention of a fish mouth opening due to a deformation of a front lower portion of the lid.
According to a further preferable embodiment, the bridging portion comprises a frame that extends around the base for creating a double-shell structure. The double shell structure can comprise the base forming an inner base shell and the frame forming an outer base shell of the cargo carrier. Thus, the frame can extend around the entire base. The frame can comprise minor cut-outs, for example providing passage regarding fixation elements. In other words, the double-shell structure can provide a twin-layer structure comprising the base as an inner layer and the frame as an outer layer. The frame can thus be manufactured having a trough shape, similar to the base itself, at least partly enclosing the base. This may be advantageous, as no centre-piece may be removed while manufacturing a frame part.
According to a further preferable embodiment, the at least one add-on portion comprises a spoiler portion attached to the lid, preferably to a rear portion of the lid, or to the base, preferably to a front portion of the base. Besides other effects mentioned, attaching a spoiler portion to the lid may reduce the flexibility of the lid and increase the stiffness or rigidity of the lid which is particularly effective in combination with a reinforced front portion of the lid that will be described later. According to a further embodiment of the cargo carrier, the add-on portion comprises two separate portions, the bridging portion and a spoiler portion. Preferably, a spoiler part is attached to a rear portion of the lid, wherein the spoiler portion can provide a rear spoiler of the cargo carrier. Such a spoiler can further provide enhanced aerodynamics of the cargo carrier in turn providing an enhanced driving stability of the vehicle. Furthermore, such a spoiler may increase the stability of the rear portion of the lid.
According to a further preferable embodiment, the spoiler portion provides a substantially flush transition between an outer surface of the spoiler portion and an outer surface of the bridging portion. In this embodiment, the add-on portion can comprise a spoiler portion attached to the rear of the lid and a bridging portion attached at least to the rear of the base. Features described with respect to transitions between the bridging portion and the lid or between the bridging portion and the base may also apply to the transition between the spoiler portion and the bridging portion according to this embodiment.
According to a further preferable embodiment, the spoiler portion comprises a gripping portion, preferably not protruding beyond a rear edge portion of the spoiler portion, for handling the cargo carrier. The gripping portion can comprise a handle that is recessed or integrated within the spoiler. Such a gripping portion can provide an efficient handling of the cargo while being aerodynamically efficient. A handle can alternatively be attached to an outer rear surface of the spoiler portion as an extra element.
According to a further aspect, the cargo carrier comprises a ground support that is provided by the base and/or the add-on portion for protecting fixation members of the cargo carrier from damage. A beneficial and preferable idea regarding this aspect can be seen in that such a ground support that is providable with the cargo carrier according to the invention on the one hand protects fixation members and on the other hand aerodynamically shields these fixation members. The base and/or the add-on portion can have a curved shape. An underside of the cargo carrier can have a concavely curved shape. The shape can be adapted to follow the shape of a roof of a vehicle. A vehicle roof shape can thus be followed by the concavely curved underside of the cargo carrier.
According to an embodiment of one of the aspects, the cargo carrier comprises fixation members for fixing the cargo carrier to a vehicle, the fixation members being arranged within a convex hull enveloping the base, the lid and the add-on portion, the base and/or the add-on portion preferably comprising at least two ground contact sections for supporting the cargo carrier on a substantially level ground. In other words, the fixation members do not protrude beyond the convex hull of the concavely curved underside of the cargo carrier. The ground contact sections can be configured and positioned such that a ground contact of the fixation members is prevented. The fixation members can be or can comprise cross bar attachment clamps or claws for attaching the cargo carrier to cross bars on a vehicle.
According to a further embodiment of one of the aspects, the ground contact sections can be aligned with the fixation members, i.e. can be arranged on the same level. Alternatively, the fixation members can protrude slightly beyond the convex hull such that the fixation members can contact the ground. Accordingly, the cargo carrier can be configured such that it can rest on both of the ground contact sections and the fixation members. In this way, a weight force of the cargo carrier is distributed between and transferred via contact sections and fixation members so that forces acting on the fixation members are at least reduced. In other words, the ground contact sections can be arranged on the underside of the cargo carrier slightly higher than the fixation members such that the fixation members receive some but not all of the contact pressure from the cargo carrier when the same is supported on the ground.
The fixation members may be movable to yield when in contact with the ground, so the ground contact sections will take the main pressure from the weight of the box.
According to a further embodiment of one of the aspects, the ground contact sections are arranged on the base. The add-on portion may thus not have ground contact sections touching the ground when the cargo carrier is supported thereon. The base can have a matte surface structure and the add-on portion can have a glossy surface structure. Accordingly, the frame and the rear spoiler of the add-on portion can have a glossy surface structure. The lid may also have a glossy surface structure. The matte surface structure is less scratch sensitive compared to the glossy surface structure. Due to the preferable configuration, only the base with its matte surface may touch the ground thus avoiding contact of the scratch sensitive, glossy surfaces of the add-on portion and the lid with the ground.
Such a configuration of the cargo carrier provides the advantageous effect, that when positioned on the vehicle roof the fixation member can be aerodynamically shielded and when positioned on the ground the fixation member can be protected from touching the ground and thus from ground contact and from damage caused thereby. The ground contact sections can be substantially point-type contact sections, wherein at least three point-type sections can be provided, and/or substantially line-type contact sections. Accordingly, the base and/or the add-on portion may partly contact the ground when positioned thereon. Accordingly, such a ground support concept can provide a wear protection of the fixation members while being particularly aerodynamically efficient at the same time.
The method for manufacturing a cargo carrier, in particular a rooftop cargo carrier, comprises the steps of forming, preferably moulding, a base having a trough shape with an interior space for stowing goods to be transported therein and a lid having a shape for covering the base. The method further comprises the step of hingedly coupling the lid with the base, so that the lid is openable and closable. Besides that, the method further comprises the step of attaching an add-on portion to at least one of the base and the lid, thereby enlarging the overall external volume of the cargo carrier. The add-on portion can have an aerodynamic effect.
According to a further aspect, a rear spoiler attachable to a cargo carrier is provided. The rear spoiler can be attachable to an openable and closable lid of the cargo carrier. The rear spoiler according to this aspect can comprise at least one feature of the spoiler portion of the add-on portion or vice versa.
Preferably, an upper edge portion of the rear spoiler can be attachable to a top surface of the lid, preferably to a step portion on the top surface. The rear spoiler can be configured to provide a substantially flush transition with the top surface of the lid. Additionally or alternatively, the rear spoiler, preferably a rear upper portion of the spoiler, can be configured to be engageable with the lid.
Preferably, a lower edge portion of the rear spoiler can be attachable to a bottom edge of the lid, preferably to a bulged edge surface. The rear spoiler can be configured to provide a substantially flush transition with the bottom edge of the lid. Additionally or alternatively, the rear spoiler, preferably a rear lower portion of the spoiler, can provide a substantially flush transition with a base of the cargo carrier and/or with an add-on portion attached to the base. A flush transition can further be provided between the frame surrounding the base and/or the lid or the bridging portion and a rear portion of the spoiler.
A further cargo carrier, in particular a rooftop cargo carrier, can be provided. The cargo carrier can comprise a base portion having a trough shape with an interior space for stowing goods to be transported therein. The interior space can be accessible through an upper opening defined by a rim portion. The cargo carrier can comprise an openable and closable lid hingedly coupled to the base portion and can be adapted to rest on the rim portion in a closed state with an edge portion of the lid contacting a laterally outer surface of the rim portion. The cargo carrier can comprise a bridging portion mounted to the base portion and being formed so as to provide a substantially seamless transition from an outer surface of the lid to an outer surface of the bridging portion when the lid is in the closed state. The components of this cargo carrier can be configured in the same way as the corresponding components of the cargo carrier described before.
Another cargo carrier, in particular rooftop cargo carrier, can be provided, wherein the cargo carrier comprises a base having a trough shape with an interior space for stowing goods to be transported therein and an openable and closable lid hingedly coupled with said base. The cargo carrier comprises an add-on portion attached to at least one of the base and the lid. The add-on portion comprises a frame surrounding said base, the frame preferably extending around the base for creating a double-shell structure comprising the base forming an inner base shell and the frame forming an outer base shell of the cargo carrier. The components of this cargo carrier can be configured in the same way as the corresponding components of the cargo carriers described before. The add-on portion can have an aerodynamic effect and/or be provided for enlarging the overall external volume of the cargo carrier.
According to a further aspect, a lid for a cargo carrier is provided. The cargo carrier can be a cargo carrier as described before and the lid can be used in combination with such a cargo carrier but also with different, for example conventional cargo carriers. The lid can comprise a reinforced front portion for reducing a flexibility of said lid at least in said reinforced front portion. The reinforced front portion can comprise a reinforcing structure, wherein said reinforcing structure can comprise at least two continuous elongate reinforcing sections. Accordingly, if the lid is used in addition to the add-on portion described above with respect to different cargo carriers, the reinforcing structure provided on the lid may be added to the cargo carrier which additionally provides rigidity in the lid.
Each of the at least two continuous elongate reinforcing sections may extend along or may be defined in an inner surface of the lid and may comprise different main extension directions. The at least two continuous elongate reinforcing sections can cross each other. Alternatively or additionally each of the at least two continuous elongate reinforcing sections can extend along a path defined by a differentiable function.
An advantageous effect of such a reinforced lid may be seen in that the rigidity of the front portion of the lid is increased thereby at least reducing, preferably fully preventing, a deformation of said lid due to internal or external forces acting on the lid, in particular forces which may lead to the undesired fish mouth opening generated due to a deformation of a front lower portion of the lid. The front portion of the lid may thus be or comprise a front stiffening or a front reinforcement of the lid. In other words, increasing the rigidity renders the front portion of the lid less prone to deformations.
The reinforcing structure may be provided on the lid or may be provided in the lid. In other words, the reinforced front portion may be a separate member applied on the lid or may be a structure integrally formed with or in the lid.
Preferably, the lid comprises an inner wall and the reinforcing structure is provided on the inner wall of the lid in the front portion of the lid. The reinforcing structure may be structured according to the shape of the inner wall of the lid such that an outer contour of the reinforcing structure at least partially follows a shape of the inner wall of the lid. In this way, a contact between the reinforcing structure and the lid can be provided which is advantageous for attaching the reinforcing structure on the inner wall of the lid. The reinforcing structure can be attached to the inner wall by means of suitable fixation members, for example rivets, or may be bonded to the inner wall, for example by means of gluing or welding.
The reinforcing structure may be formed in or as a sheet which is applied in the front portion of the lid on the inner surface of the lid. The sheet may be a single, unbroken sheet. The reinforcing structure may be formed by plastically deforming the sheet or by moulding a sheet with a specific pattern creating rigidity and stiffness. The sheet can comprise a dimension and shape allowing it to be attached to the lid in a manner such that it not only covers an inner top wall portion of the front portion of the lid but also extends at least partially downwards along an inner side wall of the lid continuing from the inner top wall. The sheet may further be configured such that corners of the inner wall of the lid remain uncovered by the sheet. This saves weight and only slightly reduces the overall rigidity added to the front portion of the lid by the sheet.
The reinforcing structure may be configured to extend over a majority of the lid front portion, preferably substantially the entire lid front portion, for example transversally across the inner surface of the lid in the front portion and from the front end portion of the inner wall of the lid up to or even past the foremost hinge attachment portions on the lid. In case the reinforcing structure comprises a sheet, preferably an unbroken one, the sheet may be configured to cover the majority of the lid front portion.
Optionally, a further reinforcing structure may be configured to extend over a lid middle portion, preferably laterally over the lid middle portion. The optional further reinforcing structure may be separate from the reinforcing structure described.
In the context of the present disclosure, the main extension direction of a reinforcing section may relate to a direction in which the respective elongate reinforcing section mainly extends in length direction. In a straight elongate reinforcing section, the main extension direction corresponds to or is parallel to a longitudinal axis of the straight elongate reinforcing section. In a curved or arcuate elongate reinforcing section, the main extension direction may be seen in a direction of a straight line connecting the end of the elongate reinforcing section. A main extension direction can be defined as a net path of an elongate reinforcing section on a projection plane parallel to the base portion of the cargo carrier. A net path is the direct path from the beginning of an elongate reinforcing section to the end of said section, without taking the real form of said section into account. For example, one of the elongate reinforcing sections may extend in cross direction of the lid, which means cross to a longitudinal direction of the lid, and another reinforcing section of the at least two elongate reinforcing sections may extend in longitudinal direction of the lid. The geometry of the reinforcing sections may thus comprise at least in part a (double) cross structure or a hash structure. At least one of the elongate reinforcing sections may be curved in one direction. Preferably, one or more of the elongate reinforcing sections comprises a curved or bent shape. Preferably, one or more of the elongate reinforcing sections comprises a straight shape. Accordingly, the reinforcement sections can extend in multiple directions.
According to a preferable configuration, one of the elongate reinforcing sections extends in longitudinal direction of the lid and another one of the elongate reinforcing sections extends in cross direction of the lid. The elongate reinforcing section extending in cross direction or transversal direction of the lid may be curved in a convex manner towards the front end of the lid. In other words, the elongate reinforcing section extending in cross direction may comprise a middle section which is bulged towards the front end of the lid. Two or more elongate reinforcing sections may penetrate each other. In a preferably configuration, two elongate reinforcing sections, preferably substantially parallel elongate reinforcing sections, extend in longitudinal direction of the lid and at least one reinforcing section crosses both of the elongate reinforcing sections. At least one of the at least one crossing reinforcing section is curved or arcuate. At least a foremost one of the at least one crossing reinforcing section may be curved corresponding to a forward wall portion of the lid, that preferably extends substantially vertically. The forward end portions of two, preferably parallel, elongate reinforcing sections and a portion of the reinforcing section crossing them may define a U-shape limiting a fixation area of a hinge or lid lifter for assisting an opening of the lid when the same is mounted on a base portion. In such a configuration, the forward end portions may in longitudinal direction of the lid extend beyond the fixation area providing additional rigidity in the fixation area.
Alternatively or in addition, at least two of the at least two continuous elongate reinforcing sections may cross each other.
Alternatively or in addition, at least one of the at least two continuous elongate reinforcing sections can preferably extend along a path defined by a differentiable function. The differentiable function may be a constantly differentiable function. Accordingly, at least one of the at least two continuous elongate reinforcing sections extends along a path without kinks or sharp bends. Hence, the path may be formed smoothly. Thus, the exact form of each of said elongate reinforcing sections can be described by a differentiable function, with a differentiable function being defined as a mathematical function whose derivative exists at each point in its domain. The mathematical function may be for example a polynomial function or a spline. Each or at least one continuous elongate reinforcing section can be formed along a kinkless, uninterrupted path.
Preferably at least one, more preferably all of the crossing elongate reinforcing sections is/are continuous, that is to say unbroken or contiguous along its/their entire length. In the context of the present disclosure the term unbroken may be understood in such a manner that at least one dimensioning of an elongate reinforcing section remains substantially constant along the entire length of the same. Depending on the configuration of the elongate reinforcing section possible dimensionings include but are not limited to a width of the elongate reinforcing section, a height of the elongate reinforcing section and a wall thickness of the elongate reinforcing section. For example, the elongate reinforcing sections may comprise a substantially constant height along their length of extension while the width may vary or may also be constant. Preferably, the width is also substantially constant. Thus, it is preferable if an unbroken distance between lid wall and a free end portion or reinforcing wall limiting said elongate reinforcing sections is created and not decreased along substantially the entire length of said elongate reinforcing sections.
An elongate reinforcing section may be considered continuous if there is no offset between adjacent portions which fully separates the portions from each other along the extension direction. However, it is possible that portions of an elongate reinforcing section are offset or shifted with respect to each other to a certain extent but in a manner that does not interrupt the elongate reinforcing section. For example, an elongate reinforcing section having a certain width may cross another elongate reinforcing section so that portions of the elongate reinforcing portion are located on both sides of the elongate reinforcing section it crosses. The elongate reinforcing portion can comprise a specific width, can meet another elongate reinforcing section and can continue on the other side in an offset or shifted manner. Accordingly, while the width of the elongate reinforcing portion may retained constant while crossing another elongate reinforcing portion, the portion entering the other elongate reinforcing section and the portion leaving the other elongate reinforcing member can be offset with respect to each other in a manner such that the portions still partially overlap. Intersecting sections between two elongate reinforcing sections do not form an interruption within the context of this description.
Preferably, each continuous elongate reinforcing section extends over a significant portion of the front portion of the lid, for example at least two thirds of front portion of the lid in longitudinal direction of the lid, more preferably over the entire front portion, which means the continuous elongate reinforcing section may extend up to and, preferably even a predetermined distance into a side wall of the lid forming an end section of the lid and in particular forming an end section or edge of the lid for contacting a base portion. Preferably, at least one of the reinforcing sections extends across the majority of the lid width.
The front portion of the lid may be the portion of the lid ranging from a hinge mechanism fixation portion on the lid, preferably ranging from a forward end of the hinge mechanism fixation portion in the longitudinal direction of the lid, up to the front end of the lid. Accordingly, the front portion of the lid may be seen as the portion of the lid protruding beyond the foremost hinge mechanisms coupled to the lid. At a forward end region of the forward portion, a hinge or lid lifter may be fixed for assisting an opening of the lid when the same is mounted on a base portion. Thus, the reinforcing structure which may be a sheet as described above may at least extend between a lid lifter and foremost hinges so that these are secured through both the lid and the reinforcement sheet. In other words, the sheet may be formed to create a double layer structure in the fixation areas of hinges and a lid lifter. A lid lifter is a structure assisting the process of lifting said lid from said base when opening said cargo carrier. A lid lifter can be a hydraulic lid lifter. Also, an open position of a lid can be maintained by said lid lifter keeping said lid in an opened position with respect to said base for loading and unloading said cargo carrier without having to hold the lid manually throughout the loading and unloading process. A hinge can be any hinge coupling said base and said lid hingedly. As a user may open said cargo carrier by lifting said lid at different positions, for instance at the side walls or at the front, different forces may be applied on the lid during the lifting process. A reinforcing structure extending at least between said hinge and said lid lifter may support said lid lifting and lid lowering process by stabilizing the lid when a user opens the lid.
The elongate reinforcing sections may be embodied as ribs or protrusions. Thus, elongate reinforcing ribs may form the elongate reinforcing sections. The ribs can be made of solid material or may comprise a hollow interior. Each rib may form a single elongate reinforcing section. Thus, according to the present disclosure a lattice or grid like structure can be embodied by the ribs which functions as reinforcement when applied on the inner wall of the front portion of the lid thereby forming the reinforced front portion of the lid.
The reinforcing structure may also be formed from moulding a sheet, preferably having a substantially constant thickness, in such a manner that channels or grooves are formed on one side of the sheet and protrusions are formed on corresponding portions on the opposite side of the sheet. The grooves or channels can comprise a specific depth resulting in protrusions on the opposite side comprising a specific height wherein the specific depth and height may be substantially constant. The channels formed on one side and the corresponding protrusions on the other side of the sheet may comprise a specific width which is preferably substantially constant over the entire length of the channels and protrusions. Deviations may occur in regions in which two channels or grooves cross each other.
The areas of the sheet between the grooves or channels may be available for fixing the reinforcing structure on the inner wall of the lid. Such areas may be referred to as fixation portions. The reinforcing structure may be formed such that the fixation portions comprise a width which is larger than the width of the grooves or channels and protrusions. This provides a large support area for supporting the reinforcing structure on the inner wall of the lid, which may be used for bonding the reinforcing structure to the inner wall of the lid, for example by gluing creating a strong bond.
The reinforcing structure may comprise ribs arranged, preferably fixedly attached, on a sheet or integrally formed with the sheet.
The reinforcing structure may comprise a grid, lattice, mesh or hash like pattern formed from elongate reinforcing sections, preferably ribs or protrusions, crossing each other. The pattern may be integrally formed with the lid so that the lid and the reinforcing structure form a unitary piece. The pattern may be formed as a separate member which is attached to the lid. The pattern may thus be an add-on part attachable to the lid.
The grid or lattice like pattern may be formed by a first group of substantially parallel ribs or protrusions and a second group of substantially parallel ribs or protrusions which are arranged angled with respect to the ribs of the first group such that they cross or penetrate the ribs of the first group. In this way, rhombic, rectangular or quadratic sections fixation portions may be created between the ribs or protrusions.
With the above reinforcing structure, a reinforcement may be created in the front of the lid, which reinforcement extends in two directions. A first reinforcement section may extend in a first direction and a second reinforcement section may extend in a second direction that is different from the first direction. The reinforcement sections extend in at least two directions, preferably in primary and secondary directions, preferably crosswise or perpendicularly to each other.
Since the reinforced front portion securely prevents the above fish mouth effect or behaviour, it is not necessary to provide a bridging portion at the front portion of the lid for additionally coupling the lid to the base or a stop member at the front inner end of a cargo carrier mounted to the base or the lid and protruding into the other one of the lid and the base to avoid that a transported load reaches the forward end of the cargo carrier and passes between the lid and the base under formation of an opening which may look like an opened fish mouth.
