An umbrella hub is provided that includes a hub body and a plurality of slots. The hub body extends between an outer periphery and a central aperture configured to receive an umbrella pole. The slots comprise a pivot zone configured to receive and retain a mounting pin of an umbrella rib or strut. The hub can be loaded in a generally horizontal direction. Deflectable surfaces enable rigid pins of the umbrella rib or strut to be engaged with the hub for pivoting therein.

The umbrella hub of claim 1, the lower portion further comprising: a surface configured to receive the locking component;a support disposed between the ring member and the outer periphery of the lower portion and between the first and a third flanges disposed adjacent to the first flange in a zone between the first and second engagement sections. 3. The umbrella hub of claim 2, wherein the support comprises first and second projections extending toward the first and third flanges, the projections being disposed at the radial locations of the apertures of the flanges and configured to reduce the lateral movement of the umbrella structural member_within the engagement section of the umbrella hub. 4. The umbrella hub of claim 2, wherein the support comprises a first lateral portion disposed between the first flange and the third flange to minimize movement of the first flange toward the third flange and away from the first engagement section. 5. The umbrella hub of claim 4, wherein the support comprises a second lateral portion disposed between the third flange and the first flange to minimize movement of the third flange toward the first flange and away from the second engagement section. 6. The umbrella hub of claim 5, wherein the first and second lateral portions are surfaces disposed at an angle that is substantially the same as an angle defined between generally radially extending portions of the first and third flanges. 7. The umbrella hub of claim 5, wherein the first and second lateral portions are arcuate portions forming a continuous structure from the third flange to the first flange. 8. The umbrella hub of claim 1, wherein both of one of the first and second flanges are configured to be deflected when the umbrella structural member is being moved into the engagement section toward the central aperture of the hub and pins of the umbrella structural member contact the flanges. 9. An umbrella hub assembly comprising: an umbrella structural member configured to support an umbrella shade member;a rotation member coupled with the umbrella structural member, the rotation member extending between opposite ends, the ends being spaced apart by a first distance;a hub body extending between an outer periphery and a central aperture configured to receive an umbrella pole;a locking device housed within the hub body, the locking device having a first set of lateral surfaces with apertures formed therethrough, the apertures opening to an internal space in the hub body, the apertures of the lateral surfaces of the first set facing each other and being spaced apart by a second distance less than the first distance, the locking device having a second set of lateral surfaces coupled with and inclined away from outer portions of the lateral surfaces of the first set such that a third distance is provided between the second set of lateral surfaces, the third distance being greater than the first distance; anda slot extending radially inwardly from the outer periphery of the hub body, the slot defined in part by the first set of lateral surfaces of the locking device;wherein at least a portion of at least one of the lateral surfaces of the second set of lateral surfaces of the locking device is deflectable to increase the third distance by an amount sufficient to permit the rotation, member of the umbrella structural member to be inserted from the periphery of the hub body. 10. The umbrella hub assembly of claim 9, wherein each of the lateral surfaces of the second set of lateral surfaces of the locking device includes a ramp structure extending from adjacent to the outer periphery toward a corresponding lateral surface of the first set of lateral surfaces. 11. The umbrella hub assembly of claim 10, wherein the locking device further comprising a flange disposed within the hub body, the flange comprising the one of the lateral surfaces of the first set of lateral surfaces and the ramp structure. 12. The umbrella hub assembly of claim 10, wherein a loading zone is disposed between a lower surface of an upper portion of the hub body and an upper surface of a lower portion of the hub body and between the outer periphery and the ramp structure. 13. The umbrella hub assembly of claim 12, wherein the locking device further comprises a ring member separate from and received between the upper and lower portions of the hub body, the ring member comprising an inner member comprising a continuous inner periphery and a plurality of flanges extending radially outward from the inner member, each of the flanges comprising the lateral surface and the ramp structure. 14. The umbrella hub assembly of claim 9, wherein the hub body houses a circumferential support disposed radially outwardly of the central aperture, such that the rotation member extends through the aperture in at least one of the first set of the lateral surfaces, the end of the rotation member is in adjacency with a surface of the circumferential support. 15. The umbrella hub assembly of claim 14, wherein the circumferential support comprises a radial support and first and second angled inner surfaces, the first and second angled inner surfaces abutting inner sides of adjacent flanges comprising the first and second sets of lateral surfaces, the circumferential support including first and second lateral projections extending from the radial support. 16. An umbrella assembly, comprising: a hub body comprising a plurality of projections and a plurality of slots disposed between projections about an outer portion of the hub, a loading zone extending from the outer portion of the hub into one of the slots, and a plurality of lateral wall apertures disposed through continuous lateral walls of the slots, the lateral wall apertures disposed in a fixed position relative to the hub body; anda plurality of umbrella structural members, one umbrella structural member disposed in each of the slots, the umbrella structural members including transversely extending pins;wherein ends of the transversely extending pins project through the lateral wall apertures into a cavity defined in part by the lateral walls, the pins being retained and able to pivot in the lateral wall apertureswherein the loading zone comprises a ramp surface on each side of the slot, wherein a circumferential distance between inner ends of the ramp surfaces is less than a distance between ends of the transversely extending in disposed in the slot; andwherein the ramp surface and the aperture on at least one side of the slot are formed on adjacent angled portions of a continuous member. 17.
