Abstract
A disposable umbrella having an elongated handle member for supporting a foldable canopy. A plurality of rib members are positionable along the underside of the canopy. A collar member is slidable along the handle and is registrable with a cam surface on the rib members for urging the rib members to open the canopy. The collar member is press-fit into friction-locking engagement with the rib members to releasably retain the canopy in the open position. The collar member, the plurality of rib members and the canopy are assembled on the handle member and secured by an end cap that is lockingly engageable with the handle member.
Claims8
An umbrella assembly comprising elongated handle means, said handle means defining a tip member at a first end and a hand grip at a second end, rib means including a disc portion having at least one rib member projecting radially from said disc portion, a plurality of said disc portions being mountable in stacked relationship on the handle means proximate the first end, said rib member further being hingedly displaceable about the disc portion from a first position substantially parallel to the handle means to a second position substantially perpendicular to the handle means, a collar member being slidable along the handle means for urging the rib member from the first position to the second position, said collar member further being adapted for frictionally engaging and selectively holding the rib member in the second position, a canopy secured to the rib member, and an end cap member being engageable with the tip member for securing the umbrella assembly.
A disposable umbrella comprising an elongated handle member, said handle member having a handgrip at a first end, a second end of said handle member being adapted for accommodating a plurality of disc members, said disc members being mounted in stacked relationship on the handle member at a predetermined distance from the second end, said disc members further including radially projecting rib members, said rib members being hingedly connected to respective disc members for movement from a retracted position substantially parallel to the handle member to an extended position substantially perpendicular to the handle member, said rib members further defining a cam surface, a canopy secured to the rib members, a collar member slidably mounted on the handle member for translation between the handgrip and the disc members, said collar member being adapted to exert a translative force on the cam surface of the rib members for urging the rib members from the retracted position to the extended position, said collar member further being adapted to frictionally engage and releasably hold the rib members in the extended position whereby the canopy is deployed.
