Rack tower assemblies and rack systems

Abstract

Rack tower assemblies and rack systems having rack tower assemblies for vehicles are disclosed. The rack tower assemblies are for detachably mounting a transversely extending crossbar to a roof of a vehicle. The rack systems include a crossbar- and a pair of rack tower assemblies.

Description

BACKGROUND

Top-mounted vehicle rack systems provide a versatile platform for transporting bicycles, skis, snowboards, boats, cargo boxes, gear racks, and/or other items. Such rack systems may include crossbars that extend side-to-side across a top or roof of a vehicle. The crossbars typically are supported on each side of the vehicle's roof by a tower, where the distance between transversely extending crossbars depends on factors such as the shape and size of the vehicle's roof.

The towers supporting the rack crossbars are securely fastened to the vehicle in some manner, to prevent the rack from slipping during use. In the case of vehicles that do not have pre-installed rails (often referred to as a “factory rack”), the fastening mechanism may include clips that attach directly to the underside of the vehicle roof, where a window of the car meets the roof. The clips may be customized to fit a particular vehicle while still allowing the doors of the vehicle to open and close normally with the rack installed.

In the case of vehicles that do have a preinstalled factory rack, the rack towers may be attached directly to the rails of the factory rack, avoiding any need to insert clips under the vehicle roof. Attachment of rack towers to a factory rack may be accomplished using clips or hooks that attach to the outer edge or underside of the rails, in a manner similar to attaching the towers directly to the vehicle roof.

Vehicle factory racks are manufactured in a wide variety of shapes and styles, and in some cases the rails of a factory rack may be provided with a groove, notch, and/or recess specifically designed for allowing attachment of a rack. The groove may be provided either on the inboard or the outboard side of the rail, and it may have a vehicle-specific shape or profile. Therefore, attachment of a tower to a grooved factory rack may require a uniquely shaped clip mechanism and/or tower body.

Due to the possible need for specially configured clips and/or towers, existing rack systems may not be configured to be mounted on a vehicle equipped with a particular factory rack. A rack manufacturer may find undesirable the need to design and offer for sale separate tower designs for every different make or model of car that uses a different factory rail configuration. Furthermore, a user may wish to move a rack from one vehicle equipped with a factory rack to another, where the rails on the two vehicles have differently shaped surfaces and attachment grooves.

SUMMARY

The invention provides rack systems and devices for carrying cargo on the roof of a vehicle. For example, towers for supporting crossbars may be configured to clamp or grip factory installed longitudinal rails.

Although interconnect structure 13 is shown to include tower body 12, mounting pad 16, and cover 28, the interconnect structure may include any suitable structure configured to connect or operatively connect the support assembly to the mount assembly, to at least partially contain the mount assembly, and/or assist the mount assembly in securing the crossbar to the roof of the vehicle.

Mount assembly 17 may include any suitable structure configured to at least partially engage one or more portions of roof rail 30, such as recess 31, to secure the crossbar to the roof rail. For example, mount assembly 17 may include at least one mounting element 18, a mounting hinge 54, and an adjustment mechanism 20, as shown in FIGS. 1 and 5.

Mounting element 18 may include any suitable structure configured to at least partially engage one or more portions of the roof rail. For example, the mounting element may include at least one mounting clip, at least one mounting hook, and/or at least one mounting claw. Additionally, the mounting element may be configured to move among a plurality of positions. For example, as shown in FIG. 2, mounting element 18 may be configured to move between a first or locking position L in which the mounting element engages the recess to secure the crossbar to the roof rail, and a second or unlocking position U in which the mounting element is spaced from the recess to allow movement of the crossbar relative to the roof rail. Although first and second mounting elements are shown in FIGS. 1-5, any suitable number of mounting elements may be used.

Mounting element 18 may move among the plurality of positions in any suitable way(s). For example, the mounting element may be pivotally connected to the tower body via a mounting hinge 54, such that the mounting element pivots among the plurality of positions about any suitable axis or axes, such as mounting axis M that is at least substantially perpendicular to the crossbar.

Although mounting element is shown to be configured to pivot about mounting axis M, the mounting element may additionally, or alternatively, be configured to pivot any suitable axis or axes. Additionally, although mounting element 18 is shown to be configured to pivot among the plurality of positions, the mounting element may alternatively, or additionally, be configured to slide, rotate, and/or move in any other suitable way among the plurality of positions.

The mounting element may include any suitable number of apertures or openings to allow the mounting element to be secured to the tower body, to allow a mounting element to be attached to one or more other mounting elements, and/or to allow the mounting element to be adjusted by adjustment mechanism 20. For example, mounting element 18 may include support aperture 24 and hinge aperture 56, as shown in FIG. 5. Support aperture 26 may include any suitable structure configured to receive a support element 24, as further discussed below. Hinge aperture 56 may include any suitable structure configured to receive mounting hinge 54 Mounting element 18 may have any suitable shape configured to engage the recess of roof rail 30. For example, the mounting element may include a first portion 18a configured to engage the recess and to be at least substantially parallel to the crossbar when the mounting element is in the locking position, as shown in FIG. 2. Additionally, or alternatively, the mounting element may include a second portion configured to engage the recess and to curve upward when the mounting element is in the locking position.

Although mounting element 18 is shown to include the first and second portions, the mounting element may include only the first or only the second portion. Additionally, although mounting element 18 is shown to curve upward when the mounting element is in the locking position, the mounting element may be shaped in any suitable way configured to engage the recess of the roof rail to secure the crossbar to the roof rail.

The mounting element may be any suitable size configured to engage the recess of the roof rail. For example, mounting element 18 may extend into at least a substantial portion of the recess, as shown in FIG. 2. Although mounting element 18 is shown to extend into at least a substantial portion of the recess, the mounting element may extend into any suitable portion of the recess.

Mounting element 18 may be located in any suitable area in the tower body. For example, mounting element 18 may be located in hollow 55. Although the mounting element is shown to be configured to move between the first and second positions, the mounting element may additionally, or alternatively, be configured to move among any suitable position(s). For example, the mounting element may be configured to move to an intermediate position in which the mounting element engages the recess while allowing a user to slide the tower assembly along the roof rail and/or allowing a user to slide the crossbar in the crossbar clamp. Additionally, although mounting element 18 is shown to be at least partially contained within hollow 55 of tower body 12, the mounting element may be located at any suitable location internal and/or external the tower body.

Mounting hinge 54 may include any suitable structure configured to secure mounting element 18 to tower body 12 and/or to allow mounting element 18 to move among the plurality of positions. The mounting hinge may be located in any suitable location of the tower body. For example, mounting hinge 54 may be located in hinge recess 53. The mounting hinge may be retained within the hinge recess in any suitable way. For example, as discussed above, fastening member 50 may block access to hinge recess 53, such that mounting hinge is retained in the hinge recess, as shown in FIG. 1.

Adjustment mechanism 20 may include any suitable structure configured to move, such as pivot, mounting element 18 among the plurality of positions. For example, the adjustment mechanism may include support element 24 and adjustment element 22, as shown in FIG. 5.

Support element 24 may include any suitable structure configured to secure two or more mounting elements together, which may allow those mounting elements to move among the plurality of positions together. The support element may be configured to be received in support aperture 26 of the mounting element. The support element may include an adjustment aperture 27, which may include any suitable structure configured to receive adjustment element 22. Although support element 24 is shown to include a support bar, the support element may include any suitable structure configured to secure two or more mounting elements together, such as securing first and second mounting elements together.

Adjustment element 22 may include any suitable structure configured to selectively adjust, move, and/or pivot the mounting element among the plurality of positions, such as between locking position L and unlocking position U. For example, the adjustment element may include a bolt 22 configured to be received in adjustment aperture 57 of tower body 12 and adjustment aperture 27 of support element 24, and to move along an adjustment axis A that is at least substantially perpendicular to the outer surface of the tower body.

As discussed above, the bolt may be configured to be accessed from the outer surface of the tower body to allow for easy installation and/or removal of the tower assembly, as shown in FIG. 3. For example, a user may use tool 62 to move adjustment element 22, thereby moving mounting element 18 among the plurality of positions. As the user moves tool 62 clockwise (or counter-clockwise), the mounting element may move between the unlocking position to the locking position. In the locking position, the mounting element may clamp on roof rail 30 against the base of the tower body to secure the crossbar to tower assembly and/or the tower assembly to the roof rail, thereby securing the crossbar to the roof of the vehicle.

Although bolt 22 is shown to move along adjustment axis A, the bolt may move along any suitable axis or axes. Additionally, although the adjustment element is shown to include bolt 22, the adjustment element may include any suitable structure configured to selectively adjust, move, and/or pivot the mounting element among the plurality of positions. Moreover, although adjustment element 22 is shown to be adjustable via a specific tool, the adjustment element may be configured to be adjustable via any suitable tools and/or by hand.

Tower assembly 10 may be provided in a kit that includes two or more different types of crossbar clamps, mounting elements, and/or mounting pads to allow a user to use the tower assembly on vehicles with different roof rails.

The present disclosure also includes a rack system 60 for a roof of a vehicle, such as a roof including a center and a pair of longitudinally extending roof rails 30 with each of those rails including a recess 31, as shown in FIG. 3. The rack system may include crossbar 40, which may be sized to extend across the roof of the vehicle. Rack system 60 also may include a pair of tower assemblies, although only one of those assemblies is shown in FIG. 3. The tower assemblies may include any suitable structure configured to secure crossbar 40 to roof rail 30. For example, each of the tower assemblies may include one or more components of the tower assemblies discussed above. Additionally, or alternatively, the rack system may consist of two or more crossbars with at least one tower assembly associated with each crossbar.
