Abstract
Abstract A device for supporting the crossbar of a vehicle roof rack and for clamping to the vehicle roof is constructed of a pedestal with a curved ramp, a follower which engages the curved ramp and is mounted to the pedestal in a movable manner, a clip (clamping element) pivotally mounted to the pedestal through the follower, and a manually operated lever arm pivotally mounted to the clamping element. The curved ramp permits the pedestal and clip combination to apply a force with substantially equal vertical and horizontal components to the vehicle, and to maintain these components at a 1:1 ratio throughout the range of motion of the lever arm which tightens the clip and pedestal down onto the vehicle.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
140 words
A device for securing a support bar to a vehicle roof, said device comprising: a pedestal adapted to support a bar along a longitudinal axis, said pedestal having a centerline intersecting said longitudinal axis to define a plane: a curved ramp on said pedestal defining a convexly curved path of travel within said plane; a follower movably mounted to said pedestal and contacting said curved ramp; a clamp member adapted to engage a vehicle door frame, said clamp member pivotally mounted to said follower; and a lever arm pivotally mounted to said clamp member and containing a protuberance contacting said follower, whereby rotation of said lever arm to urge said protuberance against said follower causes said follower to pivot relative to said clamp member and to travel along said curved ramp, thereby urging said clamp member toward said longitudinal axis.
Claim 2
Independent Claim
140 words
A device for securing a support bar to a vehicle roof, said device comprising: a pedestal adapted to support a bar along a longitudinal axis, said pedestal having a centerline intersecting said longitudinal axis to define a plane: a curved ramp on said pedestal defining a convexly curved path of travel within said plane; a follower movably mounted to said pedestal and contacting said curved ramp; a clamp member adapted to engage a vehicle door frame, said clamp member pivotally mounted to said follower; and a lever arm pivotally mounted to said clamp member and containing a protuberance contacting said follower, whereby rotation of said lever arm to urge said protuberance against said follower causes said follower to pivot relative to said clamp member and to travel along said curved ramp, thereby urging said clamp member toward said longitudinal axis.
Claim 3
Dependent Claim
49 words
A device in accordance with claim 1 in which grooves are formed in one of said protuberance and said follower, and ridges complementary to said grooves are formed in the other, to prevent slippage of said lever arm relative to said follower in a direction transverse to said plane.
Claim 4
Dependent Claim
30 words
A device in accordance with claim 1 in which said follower has first and second opposing faces, said first face contacting said ramp and said second face containing said protuberance.
Claim 5
Dependent Claim
21 words
A device in accordance with claim 1 in which said follower is movably mounted to said pedestal through a swivel connection.
Claim 6
Dependent Claim
43 words
A device in accordance with claim 1 in which said follower is movably mounted to said pedestal through a connecting arm of adjustable length, said connecting arm joined to said pedestal with a pivot connection and to said follower with a swivel connection.
Claim 7
Dependent Claim
32 words
A device in accordance with claim 1 in which said curved ramp, in addition to defining a curved path of travel within said plane, contains a transverse curvature transverse to said plane.
Claim 8
Dependent Claim
29 words
A device in accordance with claim 6 in which said follower contains a contact surface contacting said ramp, said contact surface curved in the direction transverse to said plane.
Claim 9
Dependent Claim
72 words
A device in accordance with claim 1 in which said clamp member is comprised of first and second parts, said first part pivotally mounted directly to said follower, and said second part terminating in a hook to engage said vehicle door frame, said first and second parts joined by a pivot connection permitting pivoting of said first and second parts relative to each other within a plane transverse to said longitudinal axis.
