Abstract
Abstract A sunshade support assembly includes a molded plastic support having an extension provided with a tapered external surface and a cylindrical bore. A series of slots in the extension provide radially displaceable clamping portions. A sleeve having a tapered internal surface is axially force fitted over the tapered exterior surface of the extension to set the frictional clamping force between the extensions and a leg of a sunshade support arm rotatably received in the cylindrical bore of the extension. The support arm is L-shaped and has a molded plastic elbow bearing against the support.

Total Claims: 6
Claim 1
Independent Claim
225 words
A sunshade support assembly, comprising, in combination, a support having an elongated extension provided with a generally cylindrical bore therethrough and an exterior surface tapered from one end thereof to the other end thereof, said extension including a number of slots extending from the one end thereof partially toward the other end thereof to provide the extension with a number of radially displaceable clamping portions, a generally L-shaped sunshade support arm including a pair of legs and an elbow portion, one of the legs of the support arm being generally cylindrical and extending through the cylindrical bore of the extension from the other end thereof, cooperating engageable means on the arm and on the other end of the extension to axially locate the one leg of the arm within the cylindrical bore of the extension, a sleeve member having an internal surface tapered complementary to the tapered exterior surface of the extension of the support, the sleeve member being force fitted axially along the exterior surface of the radially displaceable clamping portions of the extension to a position wherein such portions radially clamp the one leg of the support arm with a predetermined frictional force, the one leg of the support arm being normally non-rotatable relative to the extension unless a torque sufficient to overcome the predetermined frictional force is applied to the support arm.
Claim 2
Dependent Claim
225 words
A sunshade support assembly, comprising, in combination, a support having an elongated extension provided with a generally cylindrical bore therethrough and an exterior surface tapered from one end thereof to the other end thereof, said extension including a number of slots extending from the one end thereof partially toward the other end thereof to provide the extension with a number of radially displaceable clamping portions, a generally L-shaped sunshade support arm including a pair of legs and an elbow portion, one of the legs of the support arm being generally cylindrical and extending through the cylindrical bore of the extension from the other end thereof, cooperating engageable means on the arm and on the other end of the extension to axially locate the one leg of the arm within the cylindrical bore of the extension, a sleeve member having an internal surface tapered complementary to the tapered exterior surface of the extension of the support, the sleeve member being force fitted axially along the exterior surface of the radially displaceable clamping portions of the extension to a position wherein such portions radially clamp the one leg of the support arm with a predetermined frictional force, the one leg of the support arm being normally non-rotatable relative to the extension unless a torque sufficient to overcome the predetermined frictional force is applied to the support arm.
Claim 3
Dependent Claim
131 words
A sunshade support assembly comprising, in combination, a support having an elongated hollow extension provided with a tapered exterior surface, said extension being slotted to provide a number of radially displaceable clamping portions, a sunshade support arm including a leg rotatably received in the extension, a sleeve having an internal surface tapered complementary to the tapered exterior surface of the extension of the support, the sleeve being force fitted axially along the exterior surface of the radially displaceable clamping portions of the extension to a position wherein such portions radially clamp the leg of the support arm with a predetermined frictional force, the leg of the support arm being normally non-rotatable relative to the extension unless a torque sufficient to overcome the predetermined frictional force is applied to the support arm.
Claim 4
Dependent Claim
131 words
A sunshade support assembly comprising, in combination, a support having an elongated hollow extension provided with a tapered exterior surface, said extension being slotted to provide a number of radially displaceable clamping portions, a sunshade support arm including a leg rotatably received in the extension, a sleeve having an internal surface tapered complementary to the tapered exterior surface of the extension of the support, the sleeve being force fitted axially along the exterior surface of the radially displaceable clamping portions of the extension to a position wherein such portions radially clamp the leg of the support arm with a predetermined frictional force, the leg of the support arm being normally non-rotatable relative to the extension unless a torque sufficient to overcome the predetermined frictional force is applied to the support arm.
Claim 5
Dependent Claim
167 words
A sunshade support assembly comprising, in combination, a support having an elongated extension provided with a generally cylindrical bore therethrough and a tapered exterior surface, said extension including a number of circumferentially spaced slots to divide the extension into radially displaceable clamping portions, a sunshade support arm including a generally cylindrical leg rotatably received in the cylindrical bore of the extension, cooperating engageable means on the leg and on the extension axially locating the leg of the support arm relative to the extension, a sleeve having an internal surface tapered complementary to the tapered exterior surface of the extension of the support, the sleeve being axially force fitted along the exterior surface of the clamping portions of the extension to a position wherein such portions radially clamp the leg of the support arm with a predetermined frictional force, the leg of the support arm being normally non-rotatable relative to the extension unless a torque sufficient to overcome the predetermined frictional force is applied to the support arm.
