ABSTRACT:
FIELD OF THE INVENTION
This invention relates to vehicle article carriers, and more particularly to a vehicle article carrier incorporating a locking mechanism which allows a user to simultaneously place both bracket members of the article carrier in locked and unlocked positions by manually engaging a single actuating member at one side of the vehicle article carrier, and without interfering with the roof of the vehicle during manipulation of the actuating member.
BACKGROUND OF THE INVENTION
Vehicle article carriers are used in a wide variety of applications to transport a variety of articles above an outer body surface of the vehicle. Such vehicle article carriers typically include a pair of slats or elevated siderails which are fixedly mounted to the outer body surface of the vehicle, a pair of bracket members slidably disposed at ends of the slats or siderails, and a cross bar disposed between the bracket members so as to be supported above the outer body surface by the bracket members. In some applications two cross bars are employed, with the second cross bar being secured either fixedly to the slats or siderails, or being adjustably secured via its own pair of bracket members disposed slidably upon the slats or siderails.
Each bracket member used in most vehicle article carrier systems typically includes some form of locking mechanism with an actuating member for placing the locking mechanism in a locked or unlocked position. When the locking mechanism of each bracket member is in its unlocked position, both bracket members may be moved slidably along the slats or siderails to allow the cross bar therebetween to be repositioned as desired along the slats. The obvious drawback to this arrangement is that when the user desires to reposition the cross bar, first one of the bracket members must be unlocked and then the user must walk around to the opposite side of the vehicle to unlock the other bracket member. Once the cross bar has been moved to its desired position by the user, the user must manually place both of the bracket members in their locked positions. Thus, the user is presented with the inconvenience of separately locking and unlocking two bracket members whenever the cross bar is to be repositioned.
Some manufacturers of vehicle article carriers have attempted to address this problem by providing means for simultaneously locking and unlocking each bracket member via a single actuating mechanism. One such article carrier is disclosed in U.S. Pat. No. 5,190,198 to Cucheran, assigned to the assignee of the present application. Other forms of single-side releasable mechanisms are disclosed in U.S. Pat. No. 6,112,964 to Cucheran et al. The disclosures of each of these patents are hereby incorporated by reference into the present application.
While the single-side releasable crossbars disclosed in the above-referenced patents have proven to be successful and satisfactory for their intended uses, in some applications where a siderail is employed, there is very little clearance between the underside of the bracket mechanism at each end of the cross bar and the outer body surface of the vehicle. This necessitates a form of actuating member which can be opened and closed without interference with the outer body surface of the vehicle roof.
Accordingly, it would be highly desirable to provide a vehicle article carrier which incorporates a means for simultaneously locking and unlocking both bracket members from their respective slats, as well as a means for holding both bracket members in their unlocked positions once the bracket members are urged into an unlocked orientation. It would be further be highly desirable to provide such a bracket member which includes an actuating member which can be moved pivotably between locked and unlocked positions by a user without interfering with the outer body surface of the vehicle.
SUMMARY OF THE INVENTION
The above and other objects are provided by a vehicle article carrier apparatus having a single-sided release mechanism in accordance with preferred embodiments of the present invention. The apparatus generally includes a pair of siderails which are adapted to be fixedly secured to an outer body surface of a vehicle. The siderails are secured in a spaced apart, generally parallel configuration on the outer body surface of the vehicle. At least one cross bar, and more preferably a pair of cross bars, are supported span-wise between the siderails. A bracket member is disposed at each end of at least one of the cross bars which allows the cross bar to be repositioned along the siderails as may be needed.
In one preferred embodiment each bracket member further includes a locking pin which is disposed for linear, sliding movement within a housing portion of the bracket member. The locking finger is adapted to engage within one of a plurality of predefined, spaced apart openings in the siderail to allow the bracket member to be supported at a desired position along the siderails. A biasing member continuously biases a locking pin toward engagement with one of the predefined openings in the siderail. The locking pin also includes at least one transversely extending post which forms a cam follower surface, and an elongated slot.
The housing further includes an actuating member which is supported pivotally relative to the housing so that it may be easily grasped by a user with one or more fingers and moved between locked and unlocked positions. The actuating member includes at least one camming surface adapted to engage with the post on the locking pin to urge the locking pin away from the siderail when the actuating member is moved into an unlocked position. Moving the actuating member into a locked position allows a biasing element associated with the locking pin to urge the locking pin toward and into engagement with the slat.
It is a principal advantage of the bracket mechanism of the present invention that the actuating member requires very little clearance when moved between its locked and unlocked positions. This allows the cross bar to be supported closer to the outer body surface of the vehicle without interfering with use of the actuating member. Allowing the cross bar to be supported closer to the outer body surface provides a more aerodynamic article carrier assembly and can potentially reduce wind noise and aerodynamic drag which might otherwise be caused by the cross bar being positioned at a height significantly above the outer body surface.
Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
