According to yet another aspect of the invention there is provided a method of ventilating an interior cabin of a vehicle through a roof opening thereof, the method comprising:
In one arrangement, the method further includes:
The invention will now be described in conjunction with the accompanying drawings in which:
In the drawings like characters of reference indicate corresponding parts in the different figures.
The accompanying figures show a covering structure 20 for a vehicle 1 for use with a roof opening 3 therein to ventilate an interior cabin 4 of the vehicle.
Generally speaking, the vehicle 1 has a body 6 supported for movement across a support surface, for example, by a plurality of rotary traction elements 7 operatively supported for engagement with the support surface, for example, wheels when the vehicle is a land vehicle. Typically, the vehicle is self-propelled meaning it has a prime mover (not shown) such as an internal combustion engine or an electric motor operatively coupled to the rotary traction elements to drive rotation of same.
The vehicle body 6 forms the interior cabin 4 which is configured to receive occupants of the vehicle, for example it is sized and shaped to receive one or more persons and has seats. When the vehicle is self-propelled, the cabin 4 typically also includes operator controls, for example a steering wheel and pedals, for actuating and controlling the prime mover for suitably driving the traction elements.
Furthermore, the body 6 includes a roof 9 at a top of the body and a floor 10 at a bottom of the body opposite the roof. The roof 9 locates the roof opening 3, and has an interior side 12A delimiting the interior cabin 4 and an exterior side 12B opposite thereto, which is exposed to an external or ambient environment of the vehicle. The roof 9 includes a cover 14, typically in the form of a window, which is movable relative to the roof opening 3 between a closed position in which the roof opening is closed by the cover 14 and an open position in which the roof opening 3 is at least partially uncovered so that air can be exchanged between the interior cabin 4 and an exterior of the vehicle. Typically, the interior cabin 4 includes one or more trim pieces 16 (when there are plural, they may be considered as a set) along the roof opening 3 to delimit the same on the interior side 12A of the roof, which may help form a seal with the movable roof opening cover 14 in the closed position thereof, for example by carrying an annular gasket on a topside of the roof opening trim 16.
Turning now to the covering structure 20, this generally comprises a base 22 configured for resting on the exterior side 12B of the roof and defining a bottom periphery 23 of the covering structure arranged to encompass the roof opening 3, the latter two of which are more clearly shown in
The base 22 includes an annular gasket 27 encompassing the bottom opening 25 and configured to surround the roof opening 3 for sealable contact with the exterior side 12B of the roof of the vehicle. The gasket 27 may be registered with the with the bottom periphery 23, bottom opening 25 or at an intermediate location therebetween when there is provided a floor forming the base opening 23 sized smaller than the base periphery. The gasket 27 is endless, in other words it forms a closed loop. The gasket may be made of foam, air, rubber or another resiliently compressible material, which is compressible in a thickness direction.
The structure 20 further includes a peripheral wall 30 supported on the base 22 and configured to form a space 32 above the vehicle roof 9 for communication with the interior cabin 4 of the vehicle through the roof opening 3 when the roof opening cover 14 is in the open position. The peripheral wall 30 is in upstanding relation to the roof 9 of the vehicle in order to form the space or volume. The space 32 is substantially delimited by the peripheral wall 30, the base 30 and the bottom opening 25, the latter two of which typically lie in a substantially common plane.
To communicate the space 32 above the roof 9 with the ambient environment, particularly for airflow, the peripheral wall 30 locates one or more wall openings 36. The peripheral wall 30 is otherwise fluidically impermeable. When the peripheral wall has multiple openings, they face in different outward directions so as to admit into the space 32 airflow or wind from different directions.
As such, the base 22 and the peripheral wall 30 form an external portion of the covering structure 20 arranged to be disposed externally of the vehicle body 6.
To anchor the external portion to the vehicle, the covering structure 20 includes a securement device 40 connected to the external portion and configured for anchoring to the vehicle. More specifically, the securement device 40 is configured to pass through the roof opening 3, when the associated cover 14 is in the open position, for engagement in the interior cabin 4 to urge the gasket 27 into sealing engagement with the exterior side 12B of the roof. Furthermore, the securement device 40 is configured to extend from the space 32 of the external portion and through the bottom opening 25 in the base 22 for subsequent passage through the roof opening 3 and into the vehicle cabin 4.
In the illustrated arrangement, the securement device 40 includes a plurality of tensionable members 42 respectively extending from first ends 43A connected to the external portion of the covering structure and to second ends 43B free from the external portion, where there are supported retention elements 45 of the securement device configured to engage the interior cabin 4 when the tensionable members 42 are tensioned. The tensionable members 42 are connected at spaced positions to the external portion so as to distribute an applied force thereto, which is generated upon tensioning of the members 42 during or after attachment in the vehicle cabin 4. In the illustrated arrangement, the tensionable members 42 are connected to the peripheral wall 30 at positions thereon registered with the roof opening 3 in a substantially normal or perpendicular direction to a plane defined by the roof opening 3, which is typically coplanar with a portion of the roof surrounding the opening 3, so that when the securement device 40 engages the vehicle cabin, the members 42 are tensioned in the substantially normal direction to the vehicle roof to maximize a force applied to the gasket 27 for sealing engagement with the vehicle roof 9. When the vehicle 1 is rested or parked on a substantially horizontal surface, the substantially normal or perpendicular direction to the vehicle roof is a substantially vertical direction.
When the peripheral wall 30 comprises a frame formed by arcuate or bowed crossmembers arranged in an intersecting X-like configuration and panels of fluid-impermeable material supported thereon, as shown in
In the illustrated arrangement, there are provided a pair of tensionable members 42 supporting each of the retention elements 45. As such, each of the tensionable members 42 are connected at their first ends 43A to distinct locations on the peripheral wall 30 but to the respective retention element 45 at a common location thereon, such that the tensionable members 42 corresponding to a respective retention element form a V shape.
In the illustrated arrangement, the tensionable members 42 comprise lengths of resiliently stretchable material, for example elastic, such that the members 42 are automatically tensioned upon stretching between the opposite ends 43A, 43B. Thus, in a relaxed or non-tensioned state or condition of the resiliently stretchable members 42, the second ends 43B are located within the space 32 of the external portion that is external to the vehicle cabin 4 when the covering structure is mounted to the roof 9.
Also, in the illustrated arrangement, the retention elements 45 comprise rigid elongate members arranged to be sized larger than the roof opening 3 in at least one dimension thereof for butting engagement with the interior side of the roof at opposite locations across the roof opening. Thus, the retention elements 45 in the form of bars act to attach to the vehicle cabin by being sized and shaped to resist passage from the cabin 4 and through the roof opening 3 once buttingly engaged at opposite ends with the interior of the roof. Each member 45 is elongated in a respective longitudinal direction thereof and extends between opposite ends 46. In the illustrated arrangement, the members 45 extend longitudinally thereof along respective linear paths. As such, the rigid elongate members 45 are arranged to span across the roof opening 3 and extend beyond the same to provide, at opposite end portions 45A thereof defining the opposite ends 46, upwardly-facing engagement surfaces 45B for contacting the interior side of the roof at locations spaced about a periphery the roof opening. Each member 45 thus includes a bridging portion 45C intermediate the end portions 45A to interconnect the same, (upper) surfaces of which are free from engagement with the interior of the cabin. When the members 45 are in contact with the interior side of the roof in an engaged or retaining position, the members are generally horizontally oriented and otherwise generally parallel to a plane of the roof (at least at the location of the roof opening). It will be appreciated that in the engaged or retaining position, the tensionable members 42 carrying the retention elements are under tension or in respective stretched conditions. Preferably, the members 45 are in the form of bars with a flat or planar surface arranged to face upwardly in the engaged position, so as to avoid marking or otherwise damaging the interior side of the roof.
In the illustrated arrangement, the retention bars 45 are provided in opposite pairs supported in horizontally spaced relation to each other from the external portion of the covering structure. This may act to distribute the applied force of the tensioned members to the external portion of the covering structure.
To assist with passing the retention members 45 through the roof opening 3 and to fit different sizes of roof opening, the retention members 45 are adjustable in length, that is longitudinally between their ends 46, so as to be positionable between respective retracted or compacted conditions, in which the members 45 are sized in length to pass through the roof opening in generally horizontal orientations, in which the members are more horizontal than upright, and respective extended conditions, in which the end portions 45A are positioned for engagement with the interior side of the roof at opposite locations thereon. For example, each retention bar 45 comprises telescopic sections which are extensible from a central section defining a minimum length of the member.
Since the retention bars are located within the vehicle cabin and at heights above the seats, the covering structure further includes hooks 47 supported on the retention elements and arranged to be free from engagement with the interior cabin for carrying articles to be hung thereon inside the cabin.
To install the covering structure, the external portion thereof is located on the roof 9, externally of the vehicle, to register the bottom opening 25 with the roof opening 3. The roof opening 3 is substantially unobstructed or uncovered by the cover 14. Then, the securement device 40 is passed from a location external to the cabin 4, through the roof opening 3, so as to cross a plane defined thereby, and into the cabin 4 for engagement inside the vehicle. By anchoring a portion of the securement device 40 to within the vehicle cabin 4, the securement device 40 acts by tension to urge the gasket 27 into sealing engagement with an exterior surface of the vehicle roof. In this manner, fluid, particularly air, is forced to pass into the covering structure through the openings 36 and not between the covering structure and the roof.
To restrict the wall openings 36 to communicating fluid, such as air, but not animals or solid debris, for example, the wall openings comprise mesh spanning respective peripheries of the openings.

Referring to
To increase ventilating airflow from the ambient environment and into the vehicle cabin 4, the covering structure optionally includes a fan 56 configured to be driven by a power source and supported by the external portion. The fan 56 is arranged to be supported at a prescribed height relative to the vehicle body floor 10, which is at least as high as the roof opening 3.
In the illustrated arrangement, the bottom periphery 23 has a plurality of distinct sides, which typically are linear such that the periphery 23 is polygonal. Thus, the peripheral wall 30 follows the bottom periphery 23 and has a plurality of upstanding sides, which face in different directions. The wall openings 36 are located in different sides so as to face in different directions.
In the arrangement more clearly shown in
Furthermore, as shown in
The precipitation shield 53 may further comprise a distinct frame member to provide shape to a flexible sheet overtop the peripheral wall, as shown by the central member extending between the dotted lines denoting the shield of
There is also disclosed herein a method of ventilating an interior cabin of a vehicle through a roof opening thereof, which comprises the steps of:
Typically, the step of providing the covering structure over the roof opening comprises mounting the covering structure to the vehicle. In the illustrated arrangement, mounting to the vehicle comprises securing the covering structure to the interior cabin of the vehicle, via the roof opening.
To provide force ventilating airflow, the method may further include providing the powered fan, driven for rotation by a power source, in suspended condition to the covering structure at a prescribed height which is at least as high as the roof opening, and operating the fan to push air from the ambient environment and into the interior cabin of the vehicle.
Since the vehicle is mobile so as to be movable from one location to another, the covering structure is considered temporary and is intended to be assemblable and disassemblable. As such, the securement device is configured to releasably attach to the interior cabin 4, which in the illustrated arrangement is provided by hooking action or engagement of the hooks 45 reaching around the trim piece 16 to locate free ends of the hooks in engagement with the interior side of the roof.
This provides an arrangement for use with an opened or uncovered roof opening to ventilate the interior cabin, which is secured to the vehicle from inside the interior cabin. As such, this arrangement is suited for use regardless of a material of an outer surface of the vehicle roof, for example glass, aluminum or steel. This also provides an arrangement which is suited for acting as an air scoop to duct wind into the interior cabin.
As described hereinbefore, the present invention relates to a covering structure for use with a roof opening in a vehicle to ventilate an interior cabin thereof, which comprises a base supported on an exterior side of a vehicle roof, an upstanding peripheral wall enclosing a space above the roof and registered with the roof opening, one or more openings in the wall to communicate the space with an ambient environment and a securement device for anchoring to the vehicle, which is configured to extend from the space enclosed by the peripheral wall and through the roof opening to the interior cabin so as to attach inside the vehicle. The covering structure can be operated as an air scoop by closing, using movable covers, the majority of the wall openings except for those facing the wind, so that the peripheral wall acts to duct the admitted air into the cabin through the roof opening.
The scope of the claims should not be limited by the preferred embodiments set forth in the examples but should be given the broadest interpretation consistent with the specification as a whole.
