Abstract
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 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.
Claims21
An umbrella hub, comprising:
- an inner portion and an outer periphery;
- a base comprising a lower surface of the hub;
- a cover comprising an upper surface of the hub;
- a plurality of grooves in the outer periphery configured to receive umbrella ribs or struts;
- a slot disposed in the outer periphery of the cover extending transverse to one of the grooves, the slot including an opening disposed adjacent to the outer periphery of the hub and an end opposite the opening disposed radially inwardly of the opening;
- and
- a retention member having a fixed end attached to the base of the hub and a free end disposed away from the fixed end to be insertable into the cover of the hub, such that when so inserted the retention member is disposed in the slot between the opening of the slot and the end of the slot opposite the opening;
- wherein the slot permits a transverse pin coupled with the umbrella ribs or struts to be inserted into the slot from the outer periphery of the hub and where the retention member blocks the transverse pin such that inadvertent withdrawal of the transverse pin from the slot in which the retention member is disposed is prevented when the hub is fully assembled.

An umbrella hub, comprising:
- a hub body comprising a cover and a base, the cover and the base meeting at an interface, the hub body comprising a central axis extending therethrough;
- a cavity disposed in the hub body;
- a retention member disposed adjacent to the cavity and affixed to one of the cover and the base;
- a first configuration in which the cover and the base of the hub body are secured to prevent the cover and the base from being disengaged and the retention member is at a first position within the hub providing an access path for advancing an umbrella rib into the hub from an opening at an outer periphery of the hub body;
- and
- a second configuration in which the cover and the base of the hub body are secured to prevent the cover and the base from being disengaged and the retention member is at a second position within the hub body disposed across the interface and into the other of the cover and the base to which the retention member is not affixed, the retention member when so disposed blocking the access path to prevent removing the umbrella rib from the hub;
- wherein the second configuration is achieved from the first configuration through a substantially linear movement of the cover relative to the base along a direction parallel to the central axis and wherein the second configuration is achieved from the first configuration without the need for a rotation of the cover relative to the base.

An umbrella hub, comprising:
- a hub body comprising a cover and a base, the cover and the base meeting at an interface, the hub body comprising a central axis extending therethrough;
- a cavity disposed in the hub body;
- a retention member disposed adjacent to the cavity and affixed to one of the cover and the base;
- a first configuration in which the cover and the base of the hub body are secured to prevent the cover and the base from being disengaged and the retention member is at a first position within the hub providing an access path for advancing an umbrella rib into the hub from an opening at an outer periphery of the hub body;
- and
- a second configuration in which the cover and the base of the hub body are secured to prevent the cover and the base from being disengaged and the retention member is at a second position within the hub body disposed across the interface and into the other of the cover and the base to which the retention member is not affixed, the retention member when so disposed blocking the access path to prevent removing the umbrella rib from the hub;
- wherein the hub body comprises a projection of one of the cover and the base being disposed above a surface of the other of the cover and the base in the first configuration;
- and
- wherein the projection comprises a cantilevered member having a hook disposed at an end thereof to be positioned over the surface.
6 more elements
An umbrella hub, comprising:
- a hub body having an outer periphery;
- a cavity disposed in the hub body and configured to retain pivot members of umbrella ribs;
- a retention member disposed radially outward of the cavity and between the cavity and the outer periphery of the hub body the retention member having a free end;
- a first configuration in which a cover and a base of the hub body are secured to prevent the cover and the base from being disengaged by disposing a first portion of one of the cover and the base over a second portion of the other of the cover and the base such that the first portion blocks removal of the cover from the base and the retention member is at a first position within the hub providing an access path for advancing an umbrella rib into the cavity from an opening at an outer periphery of the hub body;
- and
- a second configuration in which the cover and the base of the hub body are secured to prevent the cover and the base from being disengaged and in which the retention member is at a second position within the hub body blocking the access path to prevent removing the umbrella rib from the hub, the free end of the retention member being received within a recess in the hub body.
