초록 ▼

An umbrella hub is provided that includes an inner portion, an outer periphery, a lower portion and an upper portion. A plurality of vertical grooves is disposed in the outer periphery and is configured to receive umbrella ribs or struts. A plurality of grooves extends transverse to the plurality of vertical grooves. A retention member is disposed in each of the transverse grooves. A first configuration of the hub permits deflection of the retention member such that a transverse pin coupled with the umbrella ribs or struts can be inserted into the transverse groove in which the retention member is disposed. A second configuration of the hub prevents deflection of the retention member such that inadvertent withdrawal of the pin from the transverse groove in which the retention member is disposed is prevented.

1. An assembly method, comprising: actuating a first inverted fastening unit to couple a lower portion of a hub with an upper portion of the hub, the lower and/or upper portions defining a first groove for enabling movement of a rib or strut, the upper and/or lower portions defining a plurality of second grooves disposed transversely to the first groove, retention structures disposed on at least one of the upper and lower portions;inserting one end of a first rib into the first groove and ends of shaft pins of the first rib into the second grooves;causing the shaft pins to move from an outer periphery of the hub toward the retention structures within the second grooves;disposing the shaft pins in the second grooves between the retention structures and a central axis of the hub;after actuating the first inverted fastening unit, providing relative movement between the upper portion and the lower portion in a direction aligned with the central axis of the hub to actuate a second inverted fastening unit and coupling the lower portion of the hub with the upper portion of the hub;blocking movement of the shaft pins towards the outer periphery of the hub with the retention structures and thereby retaining the shaft pins in the second groove. 2. The assembly method of claim 1, wherein the upper portion comprises the first inverted fastening unit and the lower portion comprises a first inverted groove and actuating the first inverted fastening unit engages the first inverted fastening unit with the first inverted groove. 3. The assembly method of claim 2, wherein the lower portion of the hub and the upper portion of the hub are coupled together by the second inverted fastening unit engaged with a second inverted groove. 4. The assembly method of claim 2, wherein the first inverted fastening unit comprises a deflectable cantilevered hook. 5. An assembly method, comprising: coupling in a first position a lower portion of a hub with an upper portion thereof, the hub having a cavity therein;inserting one end a rib into the hub such that an end of a transverse member of the rib is in the cavity;providing relative movement between the upper portion and the lower portion of the hub to block the transverse member from being dislodged from the cavity with a retention member extending from one of the upper portion and the lower portion of the hub to a free end;inserting the free end of the retention member into a recess in the other one of the upper portion and the lower portion of the hub that is opposite the retention member;blocking the cavity with the retention member after inserting the one end of the rib into the cavity; andcoupling the lower portion and the upper portion in a second position. 6. The assembly method of claim 5, wherein the relative movement between the upper portion and the lower portion of the hub is linear and closes a distance between the upper portion and the lower portion of the hub without required complete rotations of the hub portions relative to each other. 7. The assembly method of claim 5 further comprising securing the upper and lower portions of the hub together after inserting the free end of the retention member within the recess. 8. An assembly method, comprising: coupling a lower portion of a hub with an upper portion of the hub, the lower and/or upper portions defining a first groove for enabling movement of a rib or strut, the upper and/or lower portions defining a plurality of second grooves disposed transversely to the first groove, retention structures disposed on at least one of the upper and lower portions;inserting one end of each of a first plurality of ribs into the first groove and ends of shaft pins of the ribs into the second grooves;causing the shaft pins to move from an outer periphery of the hub toward the retention structures;disposing the shaft pins in the second grooves between the retention structures and a central axis of the hub;pressing the shaft pins against the retention structures and deflecting the retention structures;providing relative movement between the upper portion and the lower portion to move the upper and lower portions of the hub to a position in which movement of the shaft pins from the retention structures toward the outer periphery of the hub is prevented;providing relative movement between the upper portion and the lower portion to move the upper and lower portions of the hub to a position in which deflection of the retention members is prevented;wherein after providing relative movement, the retention members are substantially prevented from deflecting in the second grooves to prevent inadvertent withdrawal of the shaft pins from the second grooves. 9. An assembly method, comprising: providing a shade structure rib-receiving component having an upper portion and a lower portion, the lower portion comprising a transverse rib-receiving groove having a first and a second rib-hitching slot;engaging the upper portion with the lower portion wherein the first rib-hitching slot is in an open position and the second rib-hitching slot is in the open position engaginginserting a rib end into the transverse rib-receiving groove;inserting a first transverse side of the rib end into the first rib-hitching slot and a second transverse side of the rib end into the second rib-hitching slot;actuating an inverted coupling unit to couple the upper portion with the lower portion;blocking the first and second rib-receiving slots to retain the first and second transverse sides of the rib end within the first and second rib-receiving slots, respectively;wherein the inverted coupling unit comprises a first deflectable cantilevered hook extending a first distance from one of the upper portion and the lower portion of the shade structure rib-receiving component and a second deflectable cantilevered hook extending a second distance from one of the upper portion and the lower portion of the shade structure rib-receiving component, the second distance being greater than the first distance. 10. The assembly method of claim 9 further comprising, inserting a retention member attached to the upper portion into a cavity within the lower hub portion. 11. The assembly method of claim 10 wherein the retention member blocks the first rib-receiving slot. 12. The assembly method of claim 9, wherein the transverse rib-receiving groove is located across an interface of the upper and lower hub portions. 13. The assembly method of claim 9, wherein the first deflectable cantilevered hook is attached to the upper portion of the hub and the second deflectable cantilevered hook is attached to the lower portion of the hub.
