The biasing forces the second portion outwardly from the first portion as the umbrella assumes a collapsed position. The ribs, and canopy are thereby raised a greater than normal distance from a supporting surface of the umbrella and interference between the plurality of ribs and any object disposed at the base of the umbrella is prevented, when in the collapsed position.” The discussed references above are incorporated herein by reference.
An adjustable umbrella canopy shade has a mounting post. The mounting post has a mounting post front side and a mounting post rear side. A cantilever support is mounted to the mounting post at a lower post hinge. A tension member is mounted to the mounting post at an upper post hinge. The tension member is mounted to the cantilever support at a cantilever support middle joint. A canopy is mounted to the cantilever support. A retainer system is mounted to the mounting post and coupled to the lower post hinge so that the retainer system moves with the lower post hinge. The lower post hinge is translationally mounted on the mounting post. A handle is formed on the retainer system, and the handle is mounted to a threaded handle shaft.
Optionally, the adjustable umbrella canopy shade has a handle mounted to a handle shaft. The handle is formed as a knob. The adjustable umbrella canopy shade is formed as a cantilevered umbrella. The cantilevered umbrella has rib supports supporting ribs at rib support joints. The ribs are hinged at an upper joint. A central support is hinged to the ribs at the upper joint, and hinged to the rib supports at a lower joint so that the central support is vertically oriented. The handle shaft retainer retains the handle shaft. The handle is mounted on the mounting post front side. The handle shaft retainer is coupled to the lower post hinge.
The retainer system further includes a right guide member and a left guide member. The right guide member fits into a right guide channel, and a left guide member fits into a left guide channel. The right guide member is mounted on a right guide arm, and the left guide member is mounted on a left guide arm. The stopper is mounted to the handle shaft.
A central tube is formed within the mounting post. The stopper is configured to tighten when the handle shaft thread rotates to press the stopper against a stopper contact face. The stopper contact face is formed on the central tube. A rear chamber is formed adjacent to the central tube in the mounting post. Preferably, the adjustable umbrella canopy shade also includes a left chamber and a right chamber formed adjacent to the central tube in the mounting post. A handle shaft stopper frame made of a rigid material can retain a handle shaft stopper. T the right guide member and the left guide member engage the right guide channel and the left guide channel when the handle shaft stopper engages the stopper contact face. Preferably, the right guide channel and the left guide channel are angled toward each other at a right post flange and a left post flange. The right post flange is angled toward the left post flange to form a funnel shape so that the right guide member and the left guide member are biased toward each other when the stopper is engaged to the stopper contact face.
The following call out list of elements can be a useful guide in referencing the element numbers of the drawings.

A central support 26 can be formed as a short post that defines a triangle between the rib support 22 and the rib 21. The rib support 22 is pivotally hinged to the central support 26 at a lower joint 25 in the same way that the rib support 22 is pivotally hinged to the rib 21 at the rib support joint 23. The ribs 21 are hinged to each other radially at an upper joint 24 as well as to the central support 26. The central support 26 has an upper joint 24 connecting to the ribs 21 and a lower joint 25 connecting to the rib supports 22.
One of the ribs 21 forms a cantilever support 27 that is connected to and extends away from the upper joint 24. The cantilever support 27 is hinged to a tension member 29 at a cantilever support middle joint 28. The tension member is hinged to an upper post hinge 32 mounting post 30 and the cantilever support is hinged to a lower post hinge 33. The upper post hinge 32 is mounted above the lower post hinge 33 on the mounting post 30. The mounting post 30 may be connected to a mounting post base 31 such as a flange for installation.

The central tube is preferably cylindrical and extending the length of the post. The retainer system 40 mounts to the post 30. The retainer system 40 has a knob handle 41 with handle grip 42 that connects to a handle shaft 43. The handle shaft 43 protrudes when a user rotates the knob handle 41. The handle shaft 43 is mounted to a handle shaft retainer 44 which acts as a frame. The handle shaft retainer 44 extends upwardly to the lower post hinge bracket 34.
A handle shaft carriage 45 fits over the handle shaft retainer 44. The handle shaft carriage has a pair of extending ends, including a right end and a left end that extend to the right and left of the slot formed in the mounting post rail 36. The handle shaft has handle shaft thread 46 which is threadedly secured to the handle shaft retainer 44. The handle shaft thread 46 also continues to a handle shaft stopper frame 47 that retains a handle shaft stopper 48. The handle shaft stopper frame 47 can be made of aluminum and the handle shaft stopper is preferably elastomeric.

The retainer system 40 engages to the central tube 49 as a user turns the knob handle 41. Turning the knob handle 41 locks a stopper contact face 65 to a central tube outside surface 66. When a user engages the knob, the stopper engages the central tube and the stopper inside face 67 presses against the stopper frame retaining member 64. The stopper contact face 65 can be flat or may have grooves that engage the central tube. As the stopper contact face 65 pushes against the central tube, the stopper contact face may deform due to its elastomeric nature. A post exterior surface 60 faces the handle shaft carriage 45.
Additionally, an optional handle shaft swivel 68 can allow the stopper contact face 65 to stay at a particular orientation to the central tube outside face 66. When the stopper contact face 65 abuts the central tube outside face 66, a ridge and groove grip surface can improve friction.
The guide arms are preferably slightly flexible so that the Y shaped prong configuration allows the right guide member and the left guide member to engage with the right guide channel 54 and the left guide channel 55. The guide members, namely the right guide member and the left guide member can be made as cylinders with elastomeric grippy surfaces. The guide member grip surfaces can be mounted on wheels shaped as spools with a spool axle so that the grip surfaces rotate when the stopper contact face engages with the central tube outside surface 66. Thus, the extending compression force of the stopper against the stopper contact face 65 causes the guide members, namely the right guide member and the left guide member to engage the guide channels and such engagement can be improved if the guide arms are slightly flexible and can be formed as cantilevered leaf springs. The guide arms can engage the underside of the right post flange 61 and the left post flange 62 which are angled so that the pair of guide members has a wedge engagement to the pair of post flanges. The wedge engagement is activated when the handle knob is turned to engage the grip surface of the stopper and the guide members.
