Introduction

Popularity of outdoor recreational activities has created increased demand for different ways to carry a variety of recreational equipment on vehicles. For example, rooftop tents are mounted and used on top of a vehicle, for easy setup and transportation. The tent is typically mounted in a compact form for travel, then set up for use at a destination with at least a portion of the vehicle rooftop supporting the tent floor. A ladder allows access to the tent, and provides additional support.

Rooftop tents typically use bolts and bail with many loose parts to attach the tent to a pair of crossbars on the roof of the vehicle. These attachment mechanisms can be difficult and time consuming to implement, making an improved, simpler, more robust mounting system desirable.

This disclosure provides numerous selected examples of invented devices for mounting a tent, platform, or awning to the roof of a vehicle. Many alternatives and modifications which may or may not be expressly mentioned, are enabled, implied, currently possessed, and are supported by the disclosure.

Fig. 1 shows a rooftop rack assembly generally indicated at 10, mounted 3i5on a stationary vehicle 12. The rack assembly includes a platform 14 supporting a tent 16 on a top side 18, and a telescoping ladder 20 mounted on the platform for support and access to the tent. Tent 16 is shown in a use configuration, with platform 14 unfolded and supported by both the roof of vehicle 12 and ladder 20. In some examples, a rooftop rack assembly may include a cargo box, or other equipment mounted on a platform.

To transport the pictured example of assembly 10, ladder 20 may be telescoped and folded up, tent 16 may be collapsed, and platform 14 may be folded. A storage (for transport) configuration of assembly 10 is shown in Fig. 2. Tent 16 may be configured to collapse as platform 14 is folded, to facilitate easy stowing of assembly 10. The assembly may include a cover and straps or buckles to hold the cover in place, in order to protect assembly 10 during transportation.

Fig. 2 shows vehicle 12 with a direction of travel 22. Two raised rails 24 extending parallel to the direction of travel are fixed to the rooftop, and a pair of crossbars 26, 28 are coupled to the raised rails. Crossbars 26, 28 are perpendicular to the direction of travel with a spacing 30 between them. Each crossbar is supported by a pair of couplers 32 as part of a crossbar assembly, with one coupler on each raised rail 24. In other examples, crossbars 26, 28 may be coupled directly to the vehicle rooftop by tower-style couplers, or by any suitable couplers. The crossbars, couplers, and rails may be of sufficient structural strength to support rack assembly 10, and may have a load carrying capacity of at least 165 lbs.

Rack assembly 10 is coupled to crossbars 26, 28 by four clamps 34, 36, 38, 40. Each clamp is slidably mounted in a rail 42, which is fixed to platform 14. Rails 42 are fixed parallel to the direction of travel, and perpendicular to crossbars 26, 28. Rails 42 are disposed on platform 14 such that each clamp may be aligned with a crossbar. The clamps are configured to grip a crossbar, and each crossbar is gripped by two clamps. Clamps 34, 36 grip crossbar 26 and clamps 38, 40 grip crossbar 28.

Rails 42 are laterally spaced on platform 14 such that each clamp grips a crossbar inboard of raised rails 24 and couplers 32. In some examples, rails 42 may be laterally spaced such that each clamp grips a crossbar outboard of raised rails 24. In such examples, the clamp may grip the crossbar no more than 1 inch from a coupler 32. In other examples, rack assembly 10 may include only two rails with two clamps mounted on each rail. In such examples, each rail may extend over two crossbars so that both mounted clamps may be aligned with a crossbar.

Fig.3 shows a bottom side 44 of platform 14, including rails 42 and clamps 34, 36, 38, 40. Rails 42 are bolted to platform 14 through corresponding apertures in the rails and the platform. In some examples, platform 14 may include a plurality of apertures such that the rails may be screwed to the platform in a plurality of discrete positions. Any positions appropriate to support rack assembly 10 may be included. Rails 42 may also be attached to platform 14 by any appropriate means, such as adhesive, screw, or other fasteners.

Before installing rack assembly 10 on vehicle 12, a user may set the clamps to align with crossbars 26, 28. Each clamp is mounted in a linear track 46 of a rail 42, and slides freely along the track. Once a clamp has been slid to a selected location along rail 42, the clamp may be fixed in place relative to the rail.

In Fig. 3, clamps 34 and 38 are set with a longitudinal spacing of 48, and clamp 36 is set to an equal spacing from clamp 40. Longitudinal clamp spacing 48 may match crossbar spacing 30. Clamp 34 is also aligned with clamp 36, and clamp 38 aligned with clamp 40. A user may also adjust all four clamps in other configurations to fit the geometry of a particular vehicle or pair of crossbars.

Fig. 4 is a side view of clamp 34 and rail 42, illustrating movements of clamp 34 relative to the rail. It should be appreciated that clamps 34, 36, 38, 40 are matching, and therefore Figs. 4-10 may further illustrate any of the four clamps. Clamp 34 includes an upper body 50 that engages rail 42, and a lower body 52 with a first jaw 54 and a second jaw 56. An actuator 58 extends through the clamp 34, with a handle 60 at an end 62 of the clamp.

Clamp 34 moves in two independent ways. The clamp slides along rail 42, for example from position 64 to position 66. The clamp slides freely and may be adjusted by hand to a selected location, anywhere along the extent of rail 42. The rail includes two end caps 68 at a first and second end of the rail. End caps 68 limit the range of clamp 34, preventing the clamp from sliding past the first or second end of rail 42. End caps 68 also thereby retains clamp 34 in linear track 46.

Also, second jaw 56 moves toward or away from first jaw 54, along an axis 70 parallel to rail 42 and direction of travel 22. For example, second jaw 56 may be moved from position 72 to position 74. Motion of jaw 56 is controlled by actuator 58. By turning handle 60 in a clockwise or counterclockwise direction, a user may pull second jaw 56 toward first jaw 54 or push it away. That is, actuator 58 is configured to adjust the spacing between first jaw 54 and second jaw 56. This motion serves to open or close clamp 34. Jaw 56 may be moved to position 72 in order to insert a crossbar between jaws 54, 56, then jaw 56 may be moved to position 74 in order to grip the crossbar.

Fig. 5 shows end 62 of clamp 34, with the clamp in position 64 as shown in Fig. 4. Upper body 50 includes a recess 76 with an aperture 78 configured to receive a fix bolt 80. The fix bolt has a threaded shaft that actuates a fixation device of clamp 34, which is configured to fix the clamp in a selected location along rail 42. Fix bolt 80 includes a tooling recess to be used with a hex-wrench. In other examples, the bolt may include a tooling recess configured to be used with any appropriate tool such as a Phillips-head screw driver, Torx wrench, or socket wrench.

Returning briefly to Figs. 2-3, to install rack assembly 10 on vehicle 12, a user may measure crossbar spacing 30, and set clamps 34, 36, 38, 40 accordingly. Once the clamps are set to a generally correct configuration, a user may lightly tighten fix bolt 80 of each clamp to secure the configuration. Then, after placing rack assembly 10 on vehicle 12 as shown in Fig. 2, a user may loosen fix bolts 80 to perform additional adjustments. Once assembly 10 is correctly seated, the user may tighten fix bolts 80 to secure the assembly for transportation. Fix bolt 80 may be tightened to 2.75 Newton meters, plus or minus 0.25 Newton meters, or any torque sufficient to secure rack assembly 10 to vehicle 12 through standard acceleration and impact events. Fig. 5 also illustrates use of handle 60 to actuate clamp 34. For example, Handle 60 may be rotated from a first position 82 to a second position 84 counterclockwise as indicated by arrow 86, to open clamp 34. Handle 60 may also be rotated clockwise to close clamp 34. Actuator 58 may configured such that a comfortable number of revolutions is required to close clamp 34 on a crossbar from a fully open position. In some examples the actuator may also convey a mechanical advantage to allow a user to sufficiently tighten clamp 34 without a significant application of force.

In Fig. 5, fix bolt 80 is disposed above handle 60. The head of the bolt is entirely received in recess 76 so that handle 60 may be turned past recess 76 without interference from fix bolt 80. Handle 60 is also of a length appropriate to allow the handle to be turned without interference from end-cap 68.

Upper body 50 has two sides 88 that each include a lateral recess 90 that engages linear track 46 of rail 42. End cap 68 is shown as transparent, revealing a lip 92 on each of two side walls 94 of track 46. Track lips 92 extend inward and are received in lateral recesses 90 of clamp 34, coupling the clamp to rail 42. In some examples, recesses 90 may open into an inner surface of clamp 34 and track lips 92 may extend outward from rail 42. The complementary components may be square, round, or of any appropriate geometry. Clamp 34 may also be coupled to rail 42 by any means configured to allow sliding with minimal frictional resistance.

Fig. 6 shows linear track 46 of rail 42 more clearly. An inner surface 96 of the track includes a central channel 98 formed between two berms 100. The apertures for bolting rail 42 to platform 14 are disposed in central channel 98. Berms 100 run the length of track 46, parallel to side walls 94 therefore to lips 92. Linear track 46 has a direction 102, defined by the parallel berms and the side walls.

Fig. 7 is a perspective view of clamp 34, without rail 42. Upper body 50 is predominantly hollow, with a plurality of stiffeners 104 providing structural strength. In other examples, upper body 50 may be entirely hollow, may be solid, or may be composed of multiple materials. As shown in Fig. 7, a central cavity 106 houses a barrel nut 108 and a portion of fix bolt 80. Together, fix bolt 80, barrel nut 108, and central cavity 106 form the fixation device for clamp 34.

Central cavity 106 is generally rectangular in shape, with an extension connecting to aperture 78. The cavity is of sufficient length for the partially threaded shaft of fix bolt 80 to extend from aperture 78 to an opposite end of the cavity. Central cavity 106 is also sufficiently wide to accommodate barrel nut 108. In other examples, the central cavity may have a circular shape or any other shape that accommodates barrel nut 108 and bolt 80.

Upper body 50 has a top surface 1 10, which is retained in track 46 when clamp 34 is mounted in the track. Referring also to Fig. 6, top surface 1 10 may be close enough to lateral recesses 90 that the top surface does not contact internal surface 96 of track 46 when clamp 34 is mounted in the track. That is, side walls 94 may be of sufficient height that top surface 1 10 does not contact berms 100 when clamp 34 is mounted in track 46. This may limit frictional contact between the clamp and the track, allowing the clamp to slide freely.

Fig. 8 shows a lower portion of clamp 34, with second jaw 56 and handle 60 shown as transparent. Lower body 52 includes 6 screw channels for screwing lower body 52 to upper body 50, and two guides 1 12. First jaw 54 is formed as part of lower body 52. Second jaw 56 includes a connector portion 1 14 with three apertures and a rectangular recess. Guides 1 12 and an actuator bolt 1 16 extend through the apertures of connector portion 1 14, mounting second jaw 56 on lower body 52. A square nut 1 18 is disposed in the recess of connector portion 1 14, threaded onto actuator bolt 1 16.

The head of actuator bolt 1 16 is received in handle 60, with a hex shape configured to resist rotation. Therefore, when handle 60 is rotated, actuator bolt 1 16 is also rotated. Rotation of the bolt exerts a force on square nut 1 18, which in turn urges connector portion 1 14 along guides 1 12. Second jaw 56 is thereby moved along axis 70 when handle 60 is rotated.

Fig. 9 shows an upper portion of clamp 34, exploded to allow barrel nut 108 and central cavity 106 to be seen more clearly. Barrel nut 108 is generally cylindrical in shape, but has two shoulders 120 with flat lower surfaces. On each of two sides, central cavity 106 has a ramp 122 corresponding to shoulders 120. When assembled as shown in Fig. 7, shoulders 120 of barrel nut 108 rest on ramps 122. As shown in Fig. 9, ramps 122 curve downward away from end 62 of clamp 34 and aperture 78. At a lowest end of each ramp is a column 124, configured to serve as a stop for barrel nut 108.

Fig. 10 is a cross section of clamp 34 mounted in track 46 of rail 42 on platform 14, taken along lines 10-10 in Fig. 3. Fix bolt 80 can be seen to extend from recess 76, through a washer, aperture 78, the extension of central cavity 106, barrel nut 108, and short of the end of central cavity 106. Fix bolt 80 defines an axis of rotation 126, and is disposed such that the axis of rotation forms an angle 128 with direction 102 of track 46.

As fix bolt 80 is rotated, barrel nut 108 is drawn along the bolt and along ramps 122. When fix bolt 80 is rotated clockwise, barrel nut 108 is drawn up ramps 122 toward aperture 78. As the barrel nut moves along the ramps, the slope of the ramps changes, engaging with shoulder 120 to rotate the barrel nut. This rotation pivots fix bolt 80 about barrel nut 108, bringing the end of the bolt up and sending the head of the bolt down. Aperture 78 and the extension of central cavity 106 are configured to allow fix bolt 80 to pivot through a range of angles 128. For example, aperture 78 may be elongated on a vertical axis.

As barrel nut 108 is drawn up ramps 122, a top edge of the nut comes into contact with berms 100 of internal surface 96 of track 46, shown in Fig. 6. Any portion of fix bolt 80 higher than barrel nut 108 is received by central channel 98. Contact between barrel nut 108 and track 46 urges clamp 34 downward relative to the track and presses track lips 92 against an upper inner surface of lateral recesses 90. When barrel nut 108 is sufficiently high enough, frictional forces between the barrel nut and berms 100, and between track lips 92 and lateral recesses 90, fix clamp 34 relative to track 46. That is, when fix bolt 80 is tightened sufficiently, movement of clamp 34 is stopped in the selected position.

In the example pictured in Fig. 6, berms 100 have a flat top surface. In other examples, berms 100 may include multiple recesses spaced along track 46 and configured to partially or fully receive barrel nut 108. In such examples, the recesses may engage barrel nut 108 to prevent movement of clamp 34 relative to track 46. Track 46 may also have any internal surface 96, or structure formed on the surface, configured to engage barrel nut 108.

Referring again to Fig. 9, when fix bolt 80 is rotated counter clockwise, barrel nut 108 is urged down ramps 122 toward columns 124. Barrel nut 108 becomes entirely received in central cavity 106, and does not contact track 46. Clamp 34 is then free to slide along track 46. When barrel nut 108 contacts columns 124, fix bolt 80 is still threaded in barrel nut 108, but the bolt can no longer be rotated. Columns 124 thereby prevent fix bolt 80 being unscrewed from barrel nut 108.

Fig. 1 1 shows awning system 200 for providing shelter next to a vehicle. Awning system 200 includes flexible cover 204 which may be extended out from case 208. Legs 212 support distal side of cover 204 above the ground. Legs 212 may be provided with a telescoping mechanism which may be used to accommodate vehicles of different height, and also to provide a slant to cover 204, for example, for shade or draining purposes. Cords 216 and stakes 220 may be used to secure the positions of legs 212. Case 208 is equipped with clamps, as shown in Fig. 12, for connecting case 208 to crossbars 224 mounted on top of vehicle 228.

Fig. 12 shows details of case 208 and a preferred mechanism for connecting case 208 to crossbars 224. Case 208 includes base track 236 and clamps 240 which may be slidably adjusted along base track 236 to appropriate locations corresponding to the spacing between crossbars 224. Clamps 240 are in most respects similar to claims already shown and described above, except clamps 240 are configured for connection to a track from the side rather than from a vertical direction. More specifically, each of clamps 240 has an upwardly extending flange 244. Flange 244 has a plurality of apertures 248 for receiving bolts 252 for attaching clamp 244 to base track 236. When installing case 208 on crossbars 224, bolts 252 are inserted in inner track 256, and moved along the track to an appropriate location corresponding to the respective positions of crossbars 224, then tightened into place.
