The wings at least defining an outer edge for a canopy mounted on the umbrella frame, wherein one wing may be mounted for pivotal movement relative to the umbrella rib. The wings, or at least one of the wings, can be pivotally mounted to the mounting portion by living or other hinges. Alternatively, the wings can be pivot directly about the umbrella rib. ## Claims ### Claim 1 A tip element, for mounting to an end of a single rib of an umbrella frame, without connection to any other element of the umbrella frame, the tip element comprising a mounting portion for mounting onto a rib of an umbrella and a pair of wings, the wings having an outer edge for defining part of an edge of a canopy mounted on the umbrella frame, wherein at least one wing is mounted for pivotal movement about an axis parallel to an axis of the umbrella rib, and relative to the other wing, and wherein the tip element is integrally molded from a plastic material and said one wing is pivotally connected to the mounting portion by a living hinge. ### Claim 2 (depends on 1) A tip element as claimed in claim 1, wherein the mounting portion includes a blind bore. ### Claim 3 (depends on 1) A tip element as claimed in claim 1, wherein the outer edge of each wing is curved. ### Claim 4 (depends on 3) A tip element as claimed in claim 3, wherein the radius of curvature of the outer edge or each tip element corresponds to the length of the umbrella rib, indicative of the radius of the umbrella canopy. ### Claim 5 (depends on 1) A tip element as claimed in claim 1, wherein the other wing of said pair of wings is pivotally connected to the mounting portion by a living hinge. ### Claim 6 (depends on 1) A tip element as claimed in claim 1, wherein the mounting portion has an axis and the wings are substantially symmetrical about the axis. ### Claim 7 A tip element for mounting to an end of a single rib of an umbrella frame, without connection to any other element of the umbrella frame, the tip element being integrally molded in a plastic material and comprising a mounting portion for mounting onto a rib of an umbrella, a pair of wings extending from the mounting portion, wherein both wings are pivotally connected to the mounting portion by living hinges, for pivotal movement around about an axis parallel to an axis of the umbrella rib, the wings being symmetrical about the mounting portion. ### Claim 8 (depends on 7) A tip element as claimed in claim 7, wherein the wings taper in thickness away from the mounting portion, and at least tip portions of the wings, spaced away from the mounting portion, are sufficiently flexible, to enable the wings to at least partially wrap around an umbrella shaft. ### Claim 9 (depends on 1) An umbrella comprising: a main shaft; a plurality of ribs pivotally connected at one end thereof to an upper end of the main shaft; a support mechanism, including a slider mounted on the main shaft, and connected to the ribs, for displacing the ribs between open and closed positions; mounted on the end of each rib, a tip element as claimed in claim 1; and a canopy attached to the ribs. ### Claim 10 (depends on 9) An umbrella as claimed in claim 9, wherein the canopy includes, for each rib, extensions at least partially enclosing the corresponding tip element. ### Claim 11 (depends on 10) An umbrella as claimed in claim 10, wherein the extensions are connected to the canopy at discrete locations. ### Claim 12 (depends on 9) An umbrella as claimed in claim 9, wherein the canopy comprises a plurality of canopy pieces attached to one another along lines corresponding with the ribs of the umbrella frame, and wherein each extension comprises two extension pieces of two adjacent canopy pieces. ### Claim 13 (depends on 12) An umbrella as claimed in claim 12, wherein said two extension pieces of said two adjacent canopy pieces are attached to one another to form a pocket for enclosing a tip element. ### Claim 14 (depends on 12) An umbrella as claimed in claim 12, wherein said two extension pieces are attached to the respective canopy pieces and are separate from one another, with each extension piece enclosing one wing of a corresponding tip element. ### Claim 15 (depends on 9) An umbrella as claimed in claim 9, wherein the canopy comprises a plurality of canopy pieces attached to one another along lines corresponding with the ribs of the umbrella frame and wherein each extension comprises a single extension piece attached to the respective canopy piece. ### Claim 16 (depends on 7) An umbrella comprising: a main shaft; a plurality of ribs pivotally connected at one end thereof to an upper end of the main shaft; a support mechanism, including a slider mounted on the main shaft, and connected to the ribs, for displacing the ribs between open and closed positions; mounted on the end of each rib, on each rib a tip element as claimed in claim 7; and a canopy attached to the ribs. ### Claim 17 (depends on 16) An umbrella as claimed in claim 16, wherein the canopy includes, for each rib, extensions at least partially enclosing the corresponding tip element. ### Claim 18 (depends on 16) An umbrella as claimed in claim 16, wherein the wings are sufficiently flexible to enable the wings to wrap around the main shaft when the umbrella is in a closed configuration. ### Claim 19 (depends on 16) An umbrella as claimed in claim 16, wherein the canopy and the tip elements comprise materials that are welded together. ### Claim 20 (depends on 19) An umbrella as claimed in claim 19, wherein the canopy and the tip elements are made from plastic material. ### Claim 21 (depends on 16) An umbrella as claimed in claim 16, wherein the canopy is made from a material that is at least partially transparent and whereby the tip elements are visible through the canopy, and the tip elements have a profile that is visually attractive.
