Description
ROOF BOX FOR A VEHICLE
FIELD OF THE INVENTION
The present invention relates to vehicle roof boxes for storing luggage, cargo and/or other objects (e.g., sporting equipment).
BACKGROUND
A roof box for a vehicle is a container mountable to a roof area of the vehicle and adapted to store luggage, cargo and/or other objects (e.g., sporting equipment).
Typically, the roof box comprises a bottom part for mounting to the roof area of the vehicle and a top part movable relative to the bottom part for opening and closing the roof box. Such a roof box is often preferred over an open roof rack since it protects objects stored therein against exposure to adverse weather and environment conditions (e.g., wind, rain, snow, UV radiation, etc.) and against theft and/or vandalism.
For some existing roof boxes, each of the bottom part and the top part comprises a structure of polymeric material thermoformed using a blow molding process. In order to enhance strength and rigidity characteristics of these roof boxes, reinforcing metallic inserts are sometimes introduced in an interior space defined by the structure of polymeric material. This introduction of strengthening metallic inserts complicates manufacturing of these roof boxes.
Also, existing roof boxes provide a storage volume that is typically fixed and incapable of adaptation to accommodate different storage requirements.
There is therefore a need for improvements directed to enhancement of strength and rigidity characteristics of vehicle roof boxes. There is also a need for improvements directed to enhancing adaptability of storage volumes of vehicle roof boxes to accommodate different storage requirements.

In this embodiment, the bottom part 16 is provided with mounting holes that enable use of mounting units 20 for mounting the bottom part 16 to the rack or other structure 15 of the roof area 14. For example, each mounting unit 20 may comprise a fastening arrangement that may comprise a U-bolt or other type of bolts, nuts and possibly other structural elements (e.g., one or more bearing plates, brackets, washers, etc.). As another example, each mounting unit 20 may comprise a clamp mechanism or any other mechanism for securing the bottom part 16 to the rack or other structure 15 of the roof area 14. In other embodiments, the bottom part 16 may be provided with other types of mounting units without being provided with mounting holes.
The roof box 10 may comprise locking units 34 for locking the roof box 10 when it is closed. The bottom part 16 is provided with a respective first locking part 35, of each locking unit 34. The first locking part 35, of each locking unit 34 is adapted to interact with a second locking part 352 of that locking unit which is provided on the top part 18 in order to lock the roof box 10 when it is closed. This enables a user to selectively lock and unlock the roof box 10 when it is closed, for example, by operating a key or inputting a combination associated with each locking unit 34. The top part 18 may also be provided with handles 39 to facilitate opening and closing of the roof box 10.
As shown in Figures 8A to 8C, in this embodiment, the bottom part 16 comprises a first wall 26, and a second wall 262 that define an interior space 28. The first wall 26, is a first thermoformed sheet of polymeric material having a first peripheral portion 27, and the second wall 262 is a second thermoformed sheet of polymeric material having a second peripheral portion 272. The first peripheral portion 27, and the second peripheral portion 272 are joined together so as to form the interior space 28.

The hinge connection 40 may comprise a lateral part of the top part 18 overlapping a lateral part of the bottom part 16 and coupled thereto by fasteners 46. Various other types of hinge connections may be used in other embodiments. Also, although in this embodiment the top part 18 is movable relative to the bottom part 16 for opening and closing the roof box 10 from only one side of the roof box 10, in other embodiments, the top part 18 may be movable relative to the bottom part 16 for opening and closing the roof box 10 from either side of the roof box 10.
The roof box 10 may comprise support members 48 respectively located at a front end and a rear end of the roof box 10 and coupled to the bottom part 16 and the top part 18. The support members 48 contribute to stabilizing the top part 18 when it is moved relative to the bottom part 16 in order to open or close the roof box 10. The support members 48 may also restrict movement of the top part 18 relative to the bottom part 16 so as to limit an extent of opening of the roof box 10. Each support member 48 may comprise a cylinder pivotally coupled to the bottom part 16 and a rod pivotally coupled to the top part 18 and adapted to move within the cylinder.
Various other types of support members are possible and may be used in other embodiments.
As shown in Figures 8A to 8C, the top part 18 comprises a first wal150, and a second wall 502 that define an interior space 66. The first wall 50} is a first thermoformed sheet of polymeric material having a first peripheral portion 57, and the second wall 502 is a second thermoformed sheet of polymeric material having a second peripheral portion 572. The first peripheral portion 57i and the second peripheral portion 572 are joined together so as to form the interior space 66.
Examples of polymeric material that may be used include high molecular weight polyethylene or any other suitable plastic material. In this embodiment, and as described later on, the first wall 50, and the second wall 502, may be thermoformed via a twin-sheet forming process. In this case, the first peripheral portion 57, and the second peripheral portion 572 may be fused together.
In this embodiment, the top part 18 has a central top section 59 that is substantially horizontal and side sections 63 that project downwardly from the central top section 59.
The top part 18 comprises a plurality of strengthening elements 60, ...603 that enhance rigidity and strength characteristics of the top part 18. Each of the strengthening elements 60, ...603 comprises a respective portion 541 of the first wall 50, joined to a respective portion 561 of the second wall 502 (where j= 1, 2 or 3).

Also, the strengthening elements 60, ...603 are remote from the first peripheral portion 57, and the second peripheral portion 572 so as to enhance rigidity and strength characteristics of the top part 18.
More specifically, while the strengthening elements 60, ...603 are provided in the central top section 59 of the top part 18, the first peripheral portion 57, and the second peripheral portion 572 are part of the side sections 63 of the top part 18.
Each of the strengthening elements 60, ...603 may extend substantially longitudinally along the top part 18. Various other configurations and orientations are possible in other embodiments. Also, it is to be understood that the top part 18 may comprise one or more strengthening elements configured and located to enhance rigidity and strength characteristics of the top part 18.
It will thus be appreciated that the strengthening elements 60, ...603 enhance rigidity and strength characteristics of the top part 18. Furthermore, since they comprise respective portions of the first wall 50, and the second wall 502 of the top part 18 that are joined together, the strengthening elements 60, ...603 may be formed directly during thermoforming of the top part 18 without requiring introduction of separate strengthening inserts between the first wall 50, and the second wall 502, thereby facilitating manufacturing of the top part 18. In addition, the strengthening elements 60, ...603 may enhance aesthetic aspects of the top part 18.
As shown in Figure 3, the second wall 502 may also comprise a plurality of projections 70 projecting away from the first wall 50t and extending substantially transversely of the top part 18. The projections 70 may further contribute to enhancing structural rigidity of the top part 18. The projections 70 may also enhance aesthetics of the top part 18.
While this embodiment depicts one possible configuration and size for the top part 18, in other embodiments, the top part 18 may have various other configurations and sizes.
It will thus be appreciated that the roof box 10 provides convenient means for storing luggage, cargo and/or other objects on the roof area 14 of the vehicle 12. It will also be appreciated that various modifications of and enhancements to the roof box may be made in other embodiments.
For example, the top part 18 and the bottom part 16 may be connected via a hinge connection 40 on one side of the roof box 10. The hinge connection 40 may comprise a lateral part of the top part 18 overlapping a lateral part of the bottom part 16 and coupled thereto by fasteners 46. Various other types of hinge connections may be used in other embodiments. Also, although in this embodiment the top part 18 is movable relative to the bottom part 16 for opening and closing the roof box 10 from only one side of the roof box 10, in other embodiments, the top part 18 may be movable relative to the bottom part 16 for opening and closing the roof box 10 from either side of the roof box 10.
The roof box 10 may comprise support members 48 respectively located at a front end and a rear end of the roof box 10 and coupled to the bottom part 16 and the top part 18. The support members 48 contribute to stabilizing the top part 18 when it is moved relative to the bottom part 16 in order to open or close the roof box 10. The support members 48 may also restrict movement of the top part 18 relative to the bottom part 16 so as to limit an extent of opening of the roof box 10. Each support member 48 may comprise a cylinder pivotally coupled to the bottom part 16 and a rod pivotally coupled to the top part 18 and adapted to move within the cylinder.
Various other types of support members are possible and may be used in other embodiments.
As shown in Figures 8A to 8C, the top part 18 comprises a first wal150, and a second wall 502 that define an interior space 66. The first wall 50} is a first thermoformed sheet of polymeric material having a first peripheral portion 57, and the second wall 502 is a second thermoformed sheet of polymeric material having a second peripheral portion 572. The first peripheral portion 57i and the second peripheral portion 572 are joined together so as to form the interior space 66.
Examples of polymeric material that may be used include high molecular weight polyethylene or any other suitable plastic material. In this embodiment, and as described later on, the first wall 50, and the second wall 502, may be thermoformed via a twin-sheet forming process. In this case, the first peripheral portion 57, and the second peripheral portion 572 may be fused together.
In this embodiment, the top part 18 has a central top section 59 that is substantially horizontal and side sections 63 that project downwardly from the central top section 59.
The top part 18 comprises a plurality of strengthening elements 60, ...603 that enhance rigidity and strength characteristics of the top part 18. Each of the strengthening elements 60, ...603 comprises a respective portion 541 of the first wall 50, joined to a respective portion 561 of the second wall 502 (where j= 1, 2 or 3).

In addition, the strengthening elements 60, ...603 may enhance aesthetic aspects of the top part 18.
As shown in Figure 3, the second wall 502 may also comprise a plurality of projections 70 projecting away from the first wall 50t and extending substantially transversely of the top part 18. The projections 70 may further contribute to enhancing structural rigidity of the top part 18. The projections 70 may also enhance aesthetics of the top part 18.
While this embodiment depicts one possible configuration and size for the top part 18, in other embodiments, the top part 18 may have various other configurations and sizes.
It will thus be appreciated that the roof box 10 provides convenient means for storing luggage, cargo and/or other objects on the roof area 14 of the vehicle 12. It will also be appreciated that various modifications of and enhancements to the roof box may be made in other embodiments.
For example, in some embodiments, the first wall 26t and the second wall 262 of the bottom part 16 may be joined to form one or more strengthening elements such as the strengthening elements 60, ...603 in order to enhance rigidity and strength characteristics of the bottom part 16.
As another example, in some embodiments, the roof box 10 may be provided with features enabling accommodation of different storage requirements. Figures 10, 11, 12A and 12B illustrate embodiments in which the roof box 10 is provided with examples of such features that enable adaptability of the roof box 10 by enabling a user to selectively reconfigure the roof box 10 to facilitate storage of different objects therein.
In the embodiment shown in Figures 10 and 11, the roof box 10 is adapted to provide an extension unit 85. The extension unit 85 defines an intemal space 87 that is additional to the volume defined by the bottom part 16 and the top part 18 for storing luggage, cargo and/or other objects in the roof box 10 when it is closed. This enables the roof box 10 to store additional objects and/or certain objects that it may otherwise not be able to store (e.g., objects having dimensions preventing them from being stored in the roof box 10 without the extension unit 15 such as skis, etc.).
In this embodiment, the extension unit 85 is located at the rear end of the roof box 10 and extends longitudinally thereof. In this case, the extension unit 85 comprises an elongated body 89 that defines the internal space 87 and that is made of a rigid material such as a polymeric material. Examples of polymeric material that may be used include high molecular weight polyethylene or any other suitable plastic material. The elongated body 89 is adapted to extend through and outwardly away from an aperture (not shown) defined by the bottom part 16 and has an end portion 91 adapted to engage an internal surface of the bottom part 16 around the aperture in order to retain the elongated body 89 with the bottom part 16. A cover element (not shown) adapted to be coupled to the bottom part 16 may be used to close or cover the aperture when the extension unit 85 is not used. In other embodiments, the extension unit 85 may be held on the roof box 10 by fasteners, quick-connect mechanisms, and/or various other means.
The extension unit 85 may be implemented in various other manners in other embodiments. For example, in some embodiments, the extension unit 85 may comprise a flexible element coupled to the bottom part 16 and adapted to flexibly extend outwardly from the bottom part 16. The flexible element may comprise a piece of flexible material such as a fabric or an elastic material. In other embodiments, the extension unit 85 may comprise an arrangement of telescopic elements coupled to the bottom part 16, the telescopic elements being adapted to telescopically extend outwardly from the bottom part 16.

For example, in some embodiments, the extension unit 85 may be located on one side of the roof box 10 and extend laterally thereof.
In the embodiment shown in Figures 12A and 12B, the roof box 10 comprises a first partition 93, and a second partition 932 that are movable to define a plurality of compartments 95, ... 953. Each of the first partition 93, and the second partition 932 is adapted to separate adjacent ones of the compartments 95, ...953. The first partition 93 1 and the second partition 932 thus enable compartmentalization of the volume defined by the bottom part 16 and the top part 18 for storing luggage, cargo and/or other objects in the roof box 10. This enables storage of different objects in different ones of the compartments 95, .. .953, for example, in situations where it may be desired to store certain objects separate from other objects. This also enables storage of one or more objects in a particular one of the compartments 95, ...953 so as to limit potential movement of the one or more objects within the roof box 10 due to motion of the vehicle 12.
In this embodiment, each of the first partition 93, and the second partition 932 is pivotable relative to the central bottom section 17 of the bottom part 16 between a first position and a second position. In the first position. which is shown in Figure 12A, each of the first partition 93 I and the second partition 932 defines adjacent ones of the compartments 95, ...953. Each of the first partition 931 and the second partition 932 may be manually pivoted into the first position and held in that position by fitting its extremities into respective grooves 97 provided in the bottom part 16. In the second position, which is shown in Figure 12B, each of the first partition 93, and the second partition 9321ays down on the central bottom section 17 of the bottom part 16 and does not define any compartments. It will be appreciated that each of the first partition 93 i and the second partition 932 may independently be in the first position or the second position. As shown in Figure 12B, when both the first partition 931 and the second partition 932 are in the second position, the volume defined by the bottom part 16 and the top part 18 is not compartmentalized.
Each of the first partition 93, and the second partition 932 may be movable in various other manners in other embodiments. For example, in some embodiments, each of the first partition 93, and the second partition 932 may be slidable into the respective grooves 97 provided in the bottom part 16 so as to define adjacent ones of the compartments 95, ...953. In such embodiments, each of the first partition 93, and the second partition 932 may be removed altogether from the roof box 10 and slid into position when desired.
Each of the first partition 93, and the second partition 932 may be made of a polymeric material such as high molecular weight polyethylene or any other suitable plastic material.
While in this embodiment the roof box 10 comprises two partitions capable of forming two or three compartments, in other embodiments, the roof box 10 may comprise one or more partitions capable of forming two or more compartments.

At step 230, the second mold 88 is moved relative to the second sheet of polymeric material S2 such that the second sheet of polymeric material S2 is forced against the molding surface 90. This results in thermoforming of the second sheet of polymeric material S2 and production of the second wall 502 of the top part 18. In some embodiments, the second mold 88 may be heated to enable proper thermoforming of the second sheet of polymeric material S2.
At step 240, the first mold 80 and the second mold 88 are pressed against each other.
Temperature and pressure conditions result in the first peripheral portion 57i of the first wall 50, and the second peripheral portion 572 of the second wall 502 being fused to each other. These conditions also result in the respective portion 54; of the first wal150, of each of the strengthening elements 60, ...603 being fused to the respective portion 561 of the second wall 502 of that strengthening element, thereby effectively forming the strengthening elements 60, ...603.
