A crossmember assembly is provided for a motor vehicle having a roof with first and second rails. Each rail has a width within a range of widths, with the first and second rails being spaced from one another by distance within a range of distances. The assembly includes a crossbar having first and second ends and movable along the rails. The assembly further includes a first clamp mechanism engaged with the first end for securing the crossbar to the first rail and a second clamp mechanism engaged with the second end for securing the crossbar to the first rail. Each of the first and second clamp mechanisms includes a stanchion attached to the crossbar and having a first rail gripping surface. Each of the first and second clamp mechanisms further includes a scotch yoke, which has a second rail gripping surface and is movable between clamped and unclamped states.

A tent system includes a base system, a canopy, and one or more interconnecting members. The base system includes a first base member configured to mount to a vehicle, a second base member, and a hinge pivotally attaching the first base member to the second base member. The canopy includes a flexible membrane having a membrane edge and a canopy fastener coupled to at least a portion of the membrane edge and configured to mate with an interconnecting member fastener. The one or more interconnecting members include an interconnecting member body defining a first longitudinal edge and a second longitudinal edge, an attachment member, and the interconnecting member fastener attached to the interconnecting member body along the second longitudinal edge and configured to mate with a plurality of different canopy fasteners.

A system for providing storage on a vehicle roof is provided. The system comprises at least one partially hollow pillar for supporting the vehicle roof, a rail adapted to being raised and lowered relative to the vehicle roof between a deployed position for receiving cargo and a non-deployed position. An actuator is positioned at least partially along or within the at least one pillar for moving the rail relative to the roof. The actuator may comprise a pinion and a rack providing support for the rail. One or more supports may be connected to the rail for sliding as the rail is raised and lowered, including an active support for raising and lowering the rail in response to actuation. One or more passive supports for the rail may be slidably received in different pillars from the active support.

A carrier device for securing an accessory to a vehicle is provided. The carrier device includes a support frame, a first suction cup mounted at the first end of the support frame, and a second suction cup mounted at the second end of the support frame. The carrier device also includes a first vacuum pump configured to selectively adjust the pressure within the first suction cup, and a second vacuum pump configured to selectively adjust the pressure within the second suction cup. The suction cups may be pivotally mounted to the support frame such that the rotational position of the first and second suction cups relative to the support frame is adjustable to selectively couple the carrier device to a vehicle. The carrier device may also include a support frame having a length that is adjustable to adapt to the size of a vehicle, and/or to adapt to the size of an accessory.

A bicycle retractable bicycle cross bar adaptor includes a bar having a first tube, a second tube and a control unit. The first tube has a first connection end and the second tube has a second connection end which is movably inserted into the first connection end. The second tube includes multiple holes. The control unit includes an inner part, a switch and a sleeve. A switch is pivotably connected to the inner part and the sleeve is mounted to the inner part and the switch. The sleeve includes a flexible tongue to pivot the switch. The switch includes a rod on one end thereof. When the switch is pivoted, the rod is inserted into one of the holes of the second tube to set the length of the bar. When the rod is removed from the hole, the second tube is moved relative to the first tube.
