Abstract
A utility rack for carrying objects on a vehicle comprises an elongated carrier bar including a pair of outer carrier members each provided with a support foot adapted to rest onto the vehicle, and an elongated inner carrier member adapted to be secured at opposite ends thereof to the outer carrier members and thus form the utility rack. There are available inner carrier members of various lengths in order to meet vehicles having different spans or widths. The end user will thus buy a pair of standard outer carrier members as well as an inner carrier member suitable for this user's particular vehicle. A same inner carrier member can only be assembled to the two outer carrier members in a single position and the spacing between the support feet cannot be adjusted.
When assembled, the inner and outer carrier members form a substantially continuous support surface as well as a substantially continuous channel extending substantially the length of the carrier bar for receiving various accessories.
When assembled, the inner and outer carrier members form a substantially continuous support surface as well as a substantially continuous channel extending substantially the length of the carrier bar for receiving various accessories.

ADJUSTABLE LOAD-CARRYING
RACK FOR VEHICLES
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to utility or carrier racks for use on vehicles and, more particularly, to a rooftop load-carrying rack.
RACK FOR VEHICLES
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to utility or carrier racks for use on vehicles and, more particularly, to a rooftop load-carrying rack.
2. Description of the Prior Art Various types of utility racks are known for carrying various equipment over the rooftop of a vehicle, or even onto a trunk lid thereof. Typically, the utility rack consists of a pair of identical units each comprising a bridge member which extends transversally above the roof of the vehicle and which is detachably secured at its opposite ends to the body of the vehicle and which is provided with a pair of support members, normally at the ends of the bridge member, for supporting the bridge member onto and spaced from the vehicle roof. Generally, each unit of the utility rack is secured to the door frames or to the gutters of the vehicle. Each unit of the utility rack is adapted for releasably securing thereon various often sport-related equipment, e.g.
skis, bicycles, snowboards, etc., with the two units being spaced apart longitudinally along the roof of the vehicle such as to support the equipment at spaced apart locations thereof.
For example, United States Patent 5,115,955 issued on May 26, 1992 to Dallaire et al. discloses a ski rack comprising a support base member having one or more adjustable ski retention posts secured thereto and extending vertically thereabove. One or more abutment members extend vertically from the base member and are disposed in a spaced aligned relationship with respective ones of the retention posts. The retention posts each have flexible biasing fingers which project toward the abutment members in a ski-receiving space defined between the posts and the abutment members for applying clamping pressure against a pair of skis support on the base member in the ski-receiving space. A bridge member extends above and across the abutment members and the retention posts. Attachment elements are disposed adjacent opposed ends of the ski rack for securing the same to a vehicle and, more particularly, a strap which extends longitudinally throughout the bridge member of the ski rack is provided at its ends protruding from the ski rack with hook which are adapted to be engaged with the gutters of the vehicle with the strap comprising an intermediate rubber section within the housing of the bridge member, whereby once the hooks have been engaged on the gutters, the resilient rubber strap urges the hooks inwardly towards the ski rack thereby firmly securing the ski rack to the vehicle's gutters.
In United States Patent 5,137,195 issued on August 11, 1992 to Walter, there is disclosed a utility rack attachable to the rooftop of vehicle of various sizes. More particularly, the utility rack includes a carrier bar containing a hollow compartment. A rubber band or a spring inside this hollow compartment is attached at either end (or at both ends thereof) to a non-elastic strap which extends from the hollow compartment and outside of the carrier bar to hooks or other anchoring devices which can be detachably secured to anchor points on the vehicle and, more particularly, to the vehicle door frames. Locking mechanisms are mounted on the carrier bar to lock the non-elastic straps to the carrier bar by a pawl mechanism or by a pin.
Therefore, the utility rack is positioned on the vehicle rooftop and the non-elastic straps are then pulled by their respective hooks such as to engage these hooks to the anchor points of the vehicle with the rubber band resiliently urging the hooks inwardly towards the carrier bar for securing the utility rack to the vehicle. Then, the locking of the non-elastic straps to the carrier bar is achieved by actuating a pawl and ratchet mechanism or a pin-perforated strap locking mechanism and, more particularly, these locking mechanisms are actuated by the pivot of a pair of arms of the utility rack which are used to hold gear thereon.
As the width of the vehicle rooftop can vary significantly, it is preferable to have utility racks of different lengths such as to efficiently utilize most of the width of the rooftop to enable the utility rack to carry as much equipment as possible and also the utility rack must have a length appropriate such that it can be securely fastened to the sides of the roof. Obviously, inwardly biased straps which can be stretched away from the utility rack can be used to secure a same length utility rack to different widths of rooftop but this may demand considerable effort if the rooftop is wide, notwithstanding the fact that the utility rack does not, in the case of large vehicles, take advantage of such vehicles' wider roofs.
Accordingly, there have been proposed various utility racks which are adjustable in lengths, such as by a telescoping motion, such as to shortened or lengthened the effective length of the utility rack and position its end supports closely to the sides of the rooftop. For instance, there is known to have a permanent length carrier bar provided at its opposed ends with sliding feet or supports which may be slid inwardly or outwardly respective to the bar such as to properly position the supports onto the roof. However, this system requires that the hand user effects himself or herself the feet adjustment in addition to the fact that the hand user might have to cut the excess part of the bar if it is large than the roof in order to meet ISO standards.
In another design, the utility rack is provided with an elongated carrier bar made up of at least two sections which may be telescoped one relative to the other and with support feet being provided at the ends of the assembled composite carrier bar. With such telescopic carrier racks, the hand user must himself or herself makes the adjustment to the length of the bar and, the member which telescopes into one or more other members of the carrier bar, typically the central part thereof when telescoping in a pair of opposed female carrier bar sections, is not at the same level then the two end female sections and this causes problems for mounting of the accessories, in which the central part, being of uneven level with the remainder of the carrier bar, may not be able to receive, or conveniently receive, equipment intended to be carried by the utility rack.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
First. it must be noted that each of Figs.
1, 2, 3, 5, 6a, 6b and 7 show a single supporting unit of various utility racks but that, in practice, two such identical units are typically used in spaced apart relationship on a vehicle for supporting various loads or sporting equipment.
Now referring to Fig. 1, there is shown a schematic representation of a conventional utility rack 10 having a rigid carrier bar 12 and a pair of support members 14 in the form feet which are slidable along the ends of the carrier bar 12 such as to vary the distance between the support members 14 in accordance with particular rooftop widths. This adjustment must be made by the end user and, in some instances it becomes necessary to cut off part of the end portions of the carrier bar 12 in order that the latter does not extend beyond the width of the roof.
In Fig. 2, there is shown a telescopic utility rack 16 comprised of a pair of female bar sections 18 each provided with a foot member 20 with a central male bar section 22 being telescopically inserted in both the female bar sections 18 such that the distance between the foot members 20 can be varied by displacing the female bar sections 18 relative to the male bar section 22 as per arrows 24.
With this design, the end user must make the adjustment of the bar length and the central male bar section 22 is not at the same level as the female bar sections 18 and this causes various problems for the mounting of accessories on the utility rack 16.
Figs. 3 and 4 show a utility rack 30 which is well described in Canadian Patent Application No. 2,187,814 which was laid-open for public inspection on September 2, 1997 and which generally comprises an elongated carrier bar 32 provided at the ends thereof with retention devices 34 and a pair of support feet 36 mounted at the lower ends of the retention devices 34. The carrier bar 32 is of a unitary extruded construction and, as best seen in Fig. 4, slidably receives longitudinally therein an elongated support 38, made for instance of a hard extruded PVC, and which is adapted to receive thereon various articles without damaging the finish of the carrier bar 32 while providing friction between the carrier bar 32 and the articles carried thereby.
Obviously, this system does not provide for any adjustability between the two support feet 36, whereby various lengths of carrier bar 32 must be manufactured to meet the demands of various roof sizes.
Therefore, in accordance with the present invention, Fig. 5 schematically illustrates a utility rack 50 in which, a carrier bar 52 comprises three sections, namely a pair of identical end sections 54 each provided with a support foot 56 and a modular central section 58 adapted for connection to the end sections 54.. The modular central section 58 is available in various lengths such that an appropriate central section 58 can be selected to fit the needs of a particular vehicle, that is such that the support feet 56 can be appropriately installed on the vehicle while allowing for a maximum use of the width of the vehicle.
With reference to Figs. 6a and 6b, it is seen that each end sections 54 includes an inwardly protruded pin 60 which is engageable in a corresponding opening defined through the central section 58 such that the end sections 54 can be displaced along arrows 62 towards and into the modular central section 58 (see Fig. 6a) until the pins 60 are fully inserted in the central section 58, as seen in Fig. 6b. The two supporting modules or end sections 54 thus fit together in the central module or central section 58 and means are provided to clip these components together into an assembled position.
The bonds between the modules are done by the pins 60 which are made of steel and which have a resistance equal to that of the aluminum carrier bar 52, i.e.
its end sections 54 and central section 58. The clip resistance is equal to the steel strap which is used to hold the utility rack to the vehicle and reference is made to the strap and hook units 64 shown in Fig. 3 and which are used with the utility rack of the present invention. It is noted that, in Fig. 3, the steel strap is located within an accordion sleeve 66 but lengths the retention device 34 to the vehicle.
As it will be seen in more details hereinafter, the dismantling of the carrier bar 52 is as simple as the mounting. Basically, the central section 58 can be disengaged from the end sections 54 by inserting an elongated object, such as a pen, through a hole situated in the central section 58, this hole being hidden, in use, by the plastic extrusion slidably engaged throughout the length of the carrier bar 52 and reference is made to the support 38 illustrated in Fig. 3 which is engaged throughout the length of the carrier bar 32. In the case of the present invention, there are three such supports strips, that is one for each of the two end sections 54 and the central section 58. Therefore, with two identical end sections 54, various central sections 58 of different lengths are made available and can be purchased separately from the end sections 54 in order to meet any specific vehicle.
Furthermore, this allows for a family having more than one vehicles to have only one set of end sections 54 while being able to purchase two or more different length central sections 58 to allow the same end sections 54 to be used on different vehicles. Obviously, as mentioned hereinbefore, one requires two utility racks 50, whereby typically four end sections 54 would be sold together with the central section 58 being sold in pairs of similar length such to meet the requirements of a respective vehicle.
Now that the principle of the present invention has been fully explained, more details as to the structure to achieve the modular utility rack of the present invention will be described with reference to Figs. 7 to 14. Fig. 7 is a perspective view of the utility rack 50 although the strap and hook units 64 (see Fig. 3) are not shown on Fig. 7 but would be provided with the end sections 54. Also, the elongated support strips necessary to engage the rails defined by the end sections 54 and central section 58 of the carrier bar 52 are not shown in Fig. 7. However, a cross-section of such an elongated protective support strip 68 is shown in Fig. 13.
Again, each of the end sections 54 and modular central section 58 is provided with its respective, properly dimensioned (i.e. same length), protective support strip 68.
As seen in Fig. 7, a pair of inserts 70 are inserted in the open ends of the end sections 54. As best seen in Fig. 9, each insert 70 defines a rectangular opening 72 and a number of circular holes 74. With reference to Fig. 7, each insert 70 is secured to a respective end section 54 of the carrier bar 52 by engaging screws or rivets 76 through the end section 54 and into the holes 74 of the insert 70 thereby securing the insert 70 to the end section 54.
A gasket 78 (which is shown in details in Fig. 14) is positioned on each of the inserts 70.
The modular central section 58, which is shown from an end elevational perspective in Fig. 8, has a contour similar to that of the end sections 54 and defines an accessory receiving channel 80 as do the end sections 54. These channels 80 are adapted to receive the aforementioned protective support strips 68 or various other accessories which may be used to attach various equipment to the utility rack 50, such as brackets or other to hold skis or bicycles.
With reference to Figs. 7 and 8, the central section 58, below its channel 80, defines a substantially rectangular opening 82 adapted to receive therein the inner ends of the inserts 70.
Inside this rectangular opening 82, there are mounted a pair of spring clips 84, details of which are seen in Figs. 11 and 12. Each spring clip 84 includes a flat section 86 adapted to be secured to an upper wall 88 of the central section 58 and which delimits the rectangular opening 82 thereof (see Fig. 8).
Rivets or other are used to secure the flat section 86 of the spring clip 84 to the upper wall 88 of the central section 58. Each spring clip 84 further includes a hook section 90 which comprises an orthogonal walking portion 92 and angular portion 94.
The spring clip 84 is oriented as seen in the broken away portion of the central section 58 shown in Fig. 7 and it must be noted that a second spring clip, not visible in Fig. 7, extends in an opposite direction from that which is shown and towards the right end section 54. Therefore, when the central section 58 is engaged over the insert 70 and with the latter sliding within the rectangular opening 82, the angular portion 94 of the spring clip 84 deflect downwards upon contact with a free end 96 of the insert 70 and, once the hook section 90 reaches the rectangular opening 72 defined in the insert 70, its bias brings it back upwards into the rectangular opening 72 with the locking portion 92 engaging the insert 70 along the inner edge 98 of the insert 70 thereby preventing the end section 54 and the central section 58 from being disassembled.
If it is desired to disassemble the various sections of the carrier bar 52, the protective support strips 68 are sufficiently removed from the channels 80 to uncover a pair of openings 100 defined in the upper wall 88 of the central section 58, one such opening 100 being visible in Fig. 7. Therefore, a thin elongated object, such as a pen can be inserted downwardly through the opening 100 such as to downwardly displace against their respective bias, the hook sections 90 of the spring clips 84 out of engagement with the rectangular opening 72 of the insert 70 and, more particularly, the locking portion 92 of the spring clip 84 is disengaged from the inner edge 98 of the insert 70 thereby allowing the central section 58 from being separated from the end sections 54.
It is noted that the gasket 78 defines a rectangular opening 102 such as to be slidable onto the insert 70 and that it defines an upper channel 104 through which the elongated protective strip 68 or other accessory engaged in the channels 80 of the end sections 54 and central section 58, can extend.
With reference to Fig. 13, the elongated protective strip 68 comprises an upper support portion 106 and a pair of lower hook portions 108 adapted to engage arms 110 defined by the end sections 54 and the central section 58 at their respective channels 80, such arms 110 being shown in the case of the central section 58 in Fig. 8. With reference to Figs. 11 and 12, the east spring clip 84 further defines an opening 112 through which a rivet or other can extend for securing the spring clip 84 to the upper wall 88 of the central section 58.
For central sections 58 of any length, the spring clips 84 are positioned at a constant distance from respective ends of the central section 58 such as to be able to engage the rectangular openings 72 of the inserts 70, the relative position between the openings 72 and the ends of the end sections 54 being constant.
Figs. 15a and 15b are enclosed to show how a lever 114 of each retention device 116 (similar to the retention devices 34 of Figs. 3 and 4) can be pivoted between a collapsed position shown in Fig.
15a and an extended position shown in Fig. 15b for the purposes of tightening the strap and hook units 64 to the vehicle, as well described in aforementioned Canadian Application No. 2,186,814. It is noted that the strap portion of the strap and hook unit 64 is identified by reference numeral 118 in Figs 15a and 15b. When the lever 114 is collapsed as in Fig. 15a and Fig. 7, the protective support strips 68 of the end sections 54 and central section 58 cannot be removed and the openings 100 which are used to disengaged the central section 58 from the end sections 54 cannot be accessed. Therefore, by displacing one of the levers 114 to its extended position of Fig. 15b, the elongated protective strips 68 can be sufficiently displaced so as to reveal the openings 100 and allow the central section 58 to be dismantled from the end sections 54, perhaps to position a different central section between the end sections 54 with a view of using the resulting assembly on a car having a different roof span.
From the foregoing, it is easily understood that with a pair of identical end sections 54 and a various number of central sections 58 of different lengths, the resulting utility racks 50 can be used on any type of vehicle. One can purchase a kit of end sections 54 (typically four in all) and then an appropriate kit of central sections 58 for one given vehicle and if this user has a second vehicle requiring a utility rack of a different length, he may simply purchase the necessary central sections 58 and use them with the standard end sections 54.
skis, bicycles, snowboards, etc., with the two units being spaced apart longitudinally along the roof of the vehicle such as to support the equipment at spaced apart locations thereof.
For example, United States Patent 5,115,955 issued on May 26, 1992 to Dallaire et al. discloses a ski rack comprising a support base member having one or more adjustable ski retention posts secured thereto and extending vertically thereabove. One or more abutment members extend vertically from the base member and are disposed in a spaced aligned relationship with respective ones of the retention posts. The retention posts each have flexible biasing fingers which project toward the abutment members in a ski-receiving space defined between the posts and the abutment members for applying clamping pressure against a pair of skis support on the base member in the ski-receiving space. A bridge member extends above and across the abutment members and the retention posts. Attachment elements are disposed adjacent opposed ends of the ski rack for securing the same to a vehicle and, more particularly, a strap which extends longitudinally throughout the bridge member of the ski rack is provided at its ends protruding from the ski rack with hook which are adapted to be engaged with the gutters of the vehicle with the strap comprising an intermediate rubber section within the housing of the bridge member, whereby once the hooks have been engaged on the gutters, the resilient rubber strap urges the hooks inwardly towards the ski rack thereby firmly securing the ski rack to the vehicle's gutters.
In United States Patent 5,137,195 issued on August 11, 1992 to Walter, there is disclosed a utility rack attachable to the rooftop of vehicle of various sizes. More particularly, the utility rack includes a carrier bar containing a hollow compartment. A rubber band or a spring inside this hollow compartment is attached at either end (or at both ends thereof) to a non-elastic strap which extends from the hollow compartment and outside of the carrier bar to hooks or other anchoring devices which can be detachably secured to anchor points on the vehicle and, more particularly, to the vehicle door frames. Locking mechanisms are mounted on the carrier bar to lock the non-elastic straps to the carrier bar by a pawl mechanism or by a pin.
Therefore, the utility rack is positioned on the vehicle rooftop and the non-elastic straps are then pulled by their respective hooks such as to engage these hooks to the anchor points of the vehicle with the rubber band resiliently urging the hooks inwardly towards the carrier bar for securing the utility rack to the vehicle. Then, the locking of the non-elastic straps to the carrier bar is achieved by actuating a pawl and ratchet mechanism or a pin-perforated strap locking mechanism and, more particularly, these locking mechanisms are actuated by the pivot of a pair of arms of the utility rack which are used to hold gear thereon.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
First. it must be noted that each of Figs.
1, 2, 3, 5, 6a, 6b and 7 show a single supporting unit of various utility racks but that, in practice, two such identical units are typically used in spaced apart relationship on a vehicle for supporting various loads or sporting equipment.
Now referring to Fig. 1, there is shown a schematic representation of a conventional utility rack 10 having a rigid carrier bar 12 and a pair of support members 14 in the form feet which are slidable along the ends of the carrier bar 12 such as to vary the distance between the support members 14 in accordance with particular rooftop widths. This adjustment must be made by the end user and, in some instances it becomes necessary to cut off part of the end portions of the carrier bar 12 in order that the latter does not extend beyond the width of the roof.
In Fig. 2, there is shown a telescopic utility rack 16 comprised of a pair of female bar sections 18 each provided with a foot member 20 with a central male bar section 22 being telescopically inserted in both the female bar sections 18 such that the distance between the foot members 20 can be varied by displacing the female bar sections 18 relative to the male bar section 22 as per arrows 24.
With this design, the end user must make the adjustment of the bar length and the central male bar section 22 is not at the same level as the female bar sections 18 and this causes various problems for the mounting of accessories on the utility rack 16.
Figs. 3 and 4 show a utility rack 30 which is well described in Canadian Patent Application No. 2,187,814 which was laid-open for public inspection on September 2, 1997 and which generally comprises an elongated carrier bar 32 provided at the ends thereof with retention devices 34 and a pair of support feet 36 mounted at the lower ends of the retention devices 34. The carrier bar 32 is of a unitary extruded construction and, as best seen in Fig. 4, slidably receives longitudinally therein an elongated support 38, made for instance of a hard extruded PVC, and which is adapted to receive thereon various articles without damaging the finish of the carrier bar 32 while providing friction between the carrier bar 32 and the articles carried thereby.
Obviously, this system does not provide for any adjustability between the two support feet 36, whereby various lengths of carrier bar 32 must be manufactured to meet the demands of various roof sizes.
Therefore, in accordance with the present invention, Fig. 5 schematically illustrates a utility rack 50 in which, a carrier bar 52 comprises three sections, namely a pair of identical end sections 54 each provided with a support foot 56 and a modular central section 58 adapted for connection to the end sections 54.. The modular central section 58 is available in various lengths such that an appropriate central section 58 can be selected to fit the needs of a particular vehicle, that is such that the support feet 56 can be appropriately installed on the vehicle while allowing for a maximum use of the width of the vehicle.
With reference to Figs. 6a and 6b, it is seen that each end sections 54 includes an inwardly protruded pin 60 which is engageable in a corresponding opening defined through the central section 58 such that the end sections 54 can be displaced along arrows 62 towards and into the modular central section 58 (see Fig. 6a) until the pins 60 are fully inserted in the central section 58, as seen in Fig. 6b. The two supporting modules or end sections 54 thus fit together in the central module or central section 58 and means are provided to clip these components together into an assembled position.
The bonds between the modules are done by the pins 60 which are made of steel and which have a resistance equal to that of the aluminum carrier bar 52, i.e.
its end sections 54 and central section 58. The clip resistance is equal to the steel strap which is used to hold the utility rack to the vehicle and reference is made to the strap and hook units 64 shown in Fig. 3 and which are used with the utility rack of the present invention. It is noted that, in Fig. 3, the steel strap is located within an accordion sleeve 66 but lengths the retention device 34 to the vehicle.
As it will be seen in more details hereinafter, the dismantling of the carrier bar 52 is as simple as the mounting. Basically, the central section 58 can be disengaged from the end sections 54 by inserting an elongated object, such as a pen, through a hole situated in the central section 58, this hole being hidden, in use, by the plastic extrusion slidably engaged throughout the length of the carrier bar 52 and reference is made to the support 38 illustrated in Fig. 3 which is engaged throughout the length of the carrier bar 32. In the case of the present invention, there are three such supports strips, that is one for each of the two end sections 54 and the central section 58. Therefore, with two identical end sections 54, various central sections 58 of different lengths are made available and can be purchased separately from the end sections 54 in order to meet any specific vehicle.
Furthermore, this allows for a family having more than one vehicles to have only one set of end sections 54 while being able to purchase two or more different length central sections 58 to allow the same end sections 54 to be used on different vehicles. Obviously, as mentioned hereinbefore, one requires two utility racks 50, whereby typically four end sections 54 would be sold together with the central section 58 being sold in pairs of similar length such to meet the requirements of a respective vehicle.
Now that the principle of the present invention has been fully explained, more details as to the structure to achieve the modular utility rack of the present invention will be described with reference to Figs. 7 to 14. Fig. 7 is a perspective view of the utility rack 50 although the strap and hook units 64 (see Fig. 3) are not shown on Fig. 7 but would be provided with the end sections 54. Also, the elongated support strips necessary to engage the rails defined by the end sections 54 and central section 58 of the carrier bar 52 are not shown in Fig. 7. However, a cross-section of such an elongated protective support strip 68 is shown in Fig. 13.
Again, each of the end sections 54 and modular central section 58 is provided with its respective, properly dimensioned (i.e. same length), protective support strip 68.
As seen in Fig. 7, a pair of inserts 70 are inserted in the open ends of the end sections 54. As best seen in Fig. 9, each insert 70 defines a rectangular opening 72 and a number of circular holes 74. With reference to Fig. 7, each insert 70 is secured to a respective end section 54 of the carrier bar 52 by engaging screws or rivets 76 through the end section 54 and into the holes 74 of the insert 70 thereby securing the insert 70 to the end section 54.
A gasket 78 (which is shown in details in Fig. 14) is positioned on each of the inserts 70.
The modular central section 58, which is shown from an end elevational perspective in Fig. 8, has a contour similar to that of the end sections 54 and defines an accessory receiving channel 80 as do the end sections 54. These channels 80 are adapted to receive the aforementioned protective support strips 68 or various other accessories which may be used to attach various equipment to the utility rack 50, such as brackets or other to hold skis or bicycles.
With reference to Figs. 7 and 8, the central section 58, below its channel 80, defines a substantially rectangular opening 82 adapted to receive therein the inner ends of the inserts 70.
Inside this rectangular opening 82, there are mounted a pair of spring clips 84, details of which are seen in Figs. 11 and 12. Each spring clip 84 includes a flat section 86 adapted to be secured to an upper wall 88 of the central section 58 and which delimits the rectangular opening 82 thereof (see Fig. 8).
Rivets or other are used to secure the flat section 86 of the spring clip 84 to the upper wall 88 of the central section 58. Each spring clip 84 further includes a hook section 90 which comprises an orthogonal walking portion 92 and angular portion 94.
The spring clip 84 is oriented as seen in the broken away portion of the central section 58 shown in Fig. 7 and it must be noted that a second spring clip, not visible in Fig. 7, extends in an opposite direction from that which is shown and towards the right end section 54. Therefore, when the central section 58 is engaged over the insert 70 and with the latter sliding within the rectangular opening 82, the angular portion 94 of the spring clip 84 deflect downwards upon contact with a free end 96 of the insert 70 and, once the hook section 90 reaches the rectangular opening 72 defined in the insert 70, its bias brings it back upwards into the rectangular opening 72 with the locking portion 92 engaging the insert 70 along the inner edge 98 of the insert 70 thereby preventing the end section 54 and the central section 58 from being disassembled.
If it is desired to disassemble the various sections of the carrier bar 52, the protective support strips 68 are sufficiently removed from the channels 80 to uncover a pair of openings 100 defined in the upper wall 88 of the central section 58, one such opening 100 being visible in Fig. 7. Therefore, a thin elongated object, such as a pen can be inserted downwardly through the opening 100 such as to downwardly displace against their respective bias, the hook sections 90 of the spring clips 84 out of engagement with the rectangular opening 72 of the insert 70 and, more particularly, the locking portion 92 of the spring clip 84 is disengaged from the inner edge 98 of the insert 70 thereby allowing the central section 58 from being separated from the end sections 54.
It is noted that the gasket 78 defines a rectangular opening 102 such as to be slidable onto the insert 70 and that it defines an upper channel 104 through which the elongated protective strip 68 or other accessory engaged in the channels 80 of the end sections 54 and central section 58, can extend.
With reference to Fig. 13, the elongated protective strip 68 comprises an upper support portion 106 and a pair of lower hook portions 108 adapted to engage arms 110 defined by the end sections 54 and the central section 58 at their respective channels 80, such arms 110 being shown in the case of the central section 58 in Fig. 8. With reference to Figs. 11 and 12, the east spring clip 84 further defines an opening 112 through which a rivet or other can extend for securing the spring clip 84 to the upper wall 88 of the central section 58.
For central sections 58 of any length, the spring clips 84 are positioned at a constant distance from respective ends of the central section 58 such as to be able to engage the rectangular openings 72 of the inserts 70, the relative position between the openings 72 and the ends of the end sections 54 being constant.
Figs. 15a and 15b are enclosed to show how a lever 114 of each retention device 116 (similar to the retention devices 34 of Figs. 3 and 4) can be pivoted between a collapsed position shown in Fig.
15a and an extended position shown in Fig. 15b for the purposes of tightening the strap and hook units 64 to the vehicle, as well described in aforementioned Canadian Application No. 2,186,814. It is noted that the strap portion of the strap and hook unit 64 is identified by reference numeral 118 in Figs 15a and 15b. When the lever 114 is collapsed as in Fig. 15a and Fig. 7, the protective support strips 68 of the end sections 54 and central section 58 cannot be removed and the openings 100 which are used to disengaged the central section 58 from the end sections 54 cannot be accessed. Therefore, by displacing one of the levers 114 to its extended position of Fig. 15b, the elongated protective strips 68 can be sufficiently displaced so as to reveal the openings 100 and allow the central section 58 to be dismantled from the end sections 54, perhaps to position a different central section between the end sections 54 with a view of using the resulting assembly on a car having a different roof span.
From the foregoing, it is easily understood that with a pair of identical end sections 54 and a various number of central sections 58 of different lengths, the resulting utility racks 50 can be used on any type of vehicle. One can purchase a kit of end sections 54 (typically four in all) and then an appropriate kit of central sections 58 for one given vehicle and if this user has a second vehicle requiring a utility rack of a different length, he may simply purchase the necessary central sections 58 and use them with the standard end sections 54.
