This is a continuation of application Ser. No. 12/490,265 filed Jun. 23, 2009 issuing as U.S. Pat. No. 8,393,508, which claims priority from U.S. Provisional Patent Application Ser. No. 61/132,956 filed Jun. 23, 2008, both of which are incorporated herein by reference. Also incorporated herein by reference is U.S. Patent Application Publication No. US2006/0273123 published Dec. 7, 2006.
BACKGROUNDSports equipment racks for vehicles typically include a pair of crossbars configured to extend across a vehicle roof width-wise for securing recreational equipment items. Typically, each crossbar is attached to the vehicle roof via a pair of towers.
Many different types of rack towers are known, and may be configured to be attached to a vehicle roof in any of a number of different ways. For example, some rack towers are configured for attachment to rain gutters. Others are designed for attachment to vehicle roof rails. Roof rails are elongate, linear, rigid structures mounted to the roofs of many vehicles, often by the vehicle manufacturer. A vehicle with roof rails typically has two rails running in parallel at least partially along the length of the roof. Roof rails may include a slotted track containing one or more mounts or connectors. Roof rails may be raised or flush with respect to the vehicle roof.
One of the problems with existing towers for securing crossbars on top of vehicles is that the variability in rail configurations requires numerous different tower designs. This places a manufacturing and design burden on manufacturers which increases product costs. The complexity of rail and tower designs also complicates the purchasing process for consumers who must determine which tower design is most appropriate for a given rail configuration. Consumers typically need to select from a line of tower designs configured to fit specifically small raised rails, large raised rails, and flush rails. Reduction of the number of tower products required to fit the various types of vehicle roof rails is an important objective.
This disclosure provides numerous selected examples of invented devices for carrying cargo on or with a vehicle. Many alternatives and modifications which may or may not be expressly mentioned, are enabled, implied, currently possessed, and are therefore supported by the disclosure.
As shown in
The various structural members disclosed herein may be constructed from any suitable material, or combination of materials, such as metal, plastic, nylon, plastic, rubber, or any other materials with sufficient structural strength to withstand the loads incurred during use. Materials may be selected based on their durability, flexibility, weight, and/or aesthetic qualities.
Although the present disclosure has been provided with reference to the foregoing operational principles and embodiments, it will be apparent to those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the disclosure.

Furthermore, any aspect shown or described with reference to a particular embodiment should be interpreted to be compatible with any other embodiment, alternative, modification, or variance.
Claims
1. A rack for carrying cargo on top of a vehicle, the vehicle having a pair of rails, the rails being substantially parallel to each other and to the direction of vehicle travel, the rack comprising:
- a pair of crossbars, each crossbar having a pair of towers for mounting the crossbar on the rails of the vehicle,
- each tower including a clamp device, the clamp device having a fixed wall and a claw assembly that is slideable in a first track back and forth relative to the fixed wall, in a direction parallel to the crossbar,
- each claw assembly having a base portion connected to the first track, the base portion having a second track substantially perpendicular to the first track, and a hook member that is slideable along the second track to adjust a separation of the hook member from the first track.
2. The rack of claim 1, wherein the hook member has teeth that engage a corresponding array of teeth on the base portion to fix location of the hook member in the second track.
3. The rack of claim 1, further comprising:
- each clamp device having a screw member engaging the base portion, the screw member being parallel to the first track and having a head for manipulating the screw member, rotation of the screw member causing movement of the base portion along the first track, relative to the fixed wall.
4. A tower for connecting a crossbar to a rail on top of a vehicle comprising:
- a clamp device having a fixed wall and a claw assembly that is slideable in a first track back and forth relative to the fixed wall, in a direction parallel to the crossbar, the claw assembly having a base portion connected to the first track, the base portion having a second track substantially perpendicular to the first track, and a hook member that is slideable along the second track to adjust a separation of the hook member from the first track while the claw assembly remains at the same position in the first track.
5. The tower of claim 4, further comprising:
- a screw member engaging the base portion, the screw member being parallel to the first track and having a head for manipulating the screw member, rotation of the screw member causing movement of the base portion along the first track, relative to the fixed wall.
6. The tower of claim 5 including a housing having a compartment containing the head of the screw member, and a pivotal cover blocking access to the head of the screw member when the cover is closed, and permitting access to the head of the screw member when the cover is open.
7. A tower for connecting a crossbar to a rail on the top of a crossbar comprising:
- a housing having a crossbar gripping portion and a fixed wall descending below the crossbar gripping portion, and
- a hook member being moveable relative to the fixed wall, to operatively position the hook member independently along a first axis and a second axis,
- wherein the housing supports a track extending parallel to the second axis and transverse to the first axis, and wherein the hook member is slideable in the track to move the hook member along the second axis.
8. The tower of claim 7, wherein the first axis is substantially perpendicular to the second axis.
9. The tower of claim 7, wherein the crossbar gripping portion is configured to grip a crossbar in an orientation substantially perpendicular to the rail, the first axis being substantially parallel to the crossbar orientation.
10. The tower of claim 7, wherein the first axis is substantially perpendicular to the rail.
