Abstract
A vehicle article carrier having a locking mechanism disposed within a bracket member. The locking mechanism includes an actuating member having first and second camming surfaces, a locking pin and a clamping member. As the actuating member is moved to an unlocked position, the first camming surface cooperates with the locking pin to urge the locking pin out of engagement with an aperture in a channel of a support member of the vehicle article carrier. Simultaneously, the second camming surface causes the clamping member to be moved out of clamping engagement with shoulder portions of the channel member. When the actuating member is moved from the unlocked to the locked position, the first camming surface allows a first spring to urge the locking pin back into engagement with the aperture in the channel member. Simultaneously, the rotation of the actuating member causes the second camming surface to allow the clamping member to be urged back into clamping engagement in response to a biasing force provided by another spring. Accordingly, a dual locking and unlocking action is provided with movement of a single actuating member.

5. A vehicle article carrier comprising:
-
a pair of support members extending longitudinally along an outer body vehicle surface and fixedly secured to said outer body vehicle surface, each of said support members including a longitudinally extending channel having a plurality of apertures formed therein; a bracket member adjustably disposed on each said support member; a cross bar extending longitudinally between said bracket members and secured at its outermost ends to said bracket members; at least one of said bracket members including; an actuating member having a first camming surface and a second camming surface, said actuating member being adapted to be manually grasped and urged between a locked position and an unlocked position; a locking pin operably associated with said actuating means and movable generally linearly into and out of locking engagement with said apertures in said channel; a first biasing member operably associated with said first camming surface of said actuating member for causing said locking pin to be withdrawn from said locking engagement with one of said apertures when said actuating member is urged into said unlocked position; a clamping member operably associated with said actuating member and disposed at least partially within said channel of an associated one of said support members; a second biasing member for urging said clamping member into engagement with said channel of said associated support member, said clamping member being cooperable with said second camming surface such that movement of said actuating member towards said unlocked position causes said clamping member to be urged out of clamping engagement with said associated support member and movement of said actuating member into said locked position causes said clamping member to be urged into engagement with at least one wall portion of said channel of said associated support member. - View Dependent Claims (6, 7, 8, 9)

10. A vehicle article carrier comprising:
-
a pair of elongated support members fixedly secured to an outer body surface of a vehicle; said support members each including a channel formed therein, each said channel including a channel member having a pair of inwardly extending shoulder portions and a bottom wall portion having a plurality of spaced apart apertures extending generally linearly along a major portion of the length of its associated said channel; a bracket member slidably and adjustably disposed on each one of said support members; a cross bar fixedly secured at each of its outermost ends to said bracket members for supporting articles thereon; each of said bracket members including a locking assembly for releasably locking each of said bracket members adjustably at a selected position along said support members, each said locking assembly including; an actuating member having a manually graspable end portion, a main body portion having at least one first camming surface and at least one second camming surface, and a bore disposed concentrically within said main body portion, said actuating member being movable between a locked position and an unlocked position; a clamping member concentrically disposed within said annular main body portion and adapted to move generally linearly relative to said annular main body portion, said clamping member being movable between an unclamped position and a clamped position, wherein in said clamped position said clamping member is engaged with said inwardly extending shoulder portions of its associated channel member; a locking pin disposed concentrically within said bore of said clamping member and movable longitudinally therein; a first biasing member disposed concentrically within said bore for biasing said locking pin such that an outermost end portion thereof extends into locking engagement with a selected one of said apertures in said bottom wall portion of said associated channel member when said locking pin is positioned over said selected aperture; a retaining member for retaining said locking pin at least partially within said clamping member against said biasing force of said first biasing member; a second biasing member for biasing said clamping member into said clamping engagement with said inwardly extending shoulder portions of said associated channel member when said actuating member is in said locked position; said first camming surface causing said retaining means to urge said locking pin linearly away from said bottom wall portion of said channel member when said manually graspable end portion of said actuating member is moved from said locked position to said unlocked position; and said second camming surface causing said clamping member to be urged away from said inwardly extending shoulder portions and therefore out of locking engagement with said associated channel member when said manually graspable end portion is moved from said locked position to said unlocked position. - View Dependent Claims (11, 12, 13)

14. A vehicle article carrier comprising:
-
a pair of support members extending longitudinally along an outer body vehicle surface and fixedly secured to said outer body vehicle surface; a bracket member disposed on at least one of said support members; a cross bar secured to said bracket member such that movement of said bracket member along said one support member allows said cross bar to be adjustably positioned relative to said support members; said bracket member including a locking assembly for releasably securing said bracket member to said one support member at a selected position along a length of said one support member; said locking assembly including; an actuating member having a manually graspable portion, a first camming surface and a second camming surface; a locking member; a clamping member; wherein said first camming surface operates to urge said locking member into locking engagement with said one support member when said actuating member is urged into a locked position and to enable said locking member to be moved out of locking engagement when said actuating member is moved into an unlocked position; and wherein said second camming surface operates to urge said clamping member into clamping engagement with said one support member when said actuating member is moved into said locked position, and to enable said clamping member to be moved out of said clamping engagement when said actuating member is moved into said unlocked position. - View Dependent Claims (15, 16)
