Abstract:
An umbrella is provided with a frame including a shank, a handle at a lower end of the shank, a grommet at an upper end of the shank, a runner slidably disposed on the shank between the handle and the grommet, ribs radially extending from the grommet, and stretchers having two ends pivotably secured to the runner and an intermediate portion of the rib respectively; and a canopy assembly including a canopy secured in covering relation on the ribs, protection members each secured to an edge portion of an inner surface of the canopy adjacent to a tip of each rib, and rib tip protection elements each secured to both the protection member and the inner surface of the canopy. Each rib has an end releasably inserted into the rib tip protection element.
Abstract:
An umbrella shank is provided with an FRP inner tube (10); an FRP outer tube (20) for receipt of the inner tube (10); a spring biased moving mechanism (30) including an upper member (31) having a longitudinal groove (311), and a lower member (32) having a longitudinal groove (321) aligned with the groove (311) wherein the lower member (32) is inserted into the inner tube (10), the upper member (31) is on the top of the inner tube (10), and the upper member (31) is in the outer tube (20); a fixing mechanism (40) in an upper portion of the outer tube (20); and a linking mechanism (60) in the outer tube (20) and including a rod (62) having a top secured to the fixing mechanism (40) and a bottom secured to a bottom of the lower member (32), and partially disposed in the grooves (311, 321).
Abstract:
An umbrella includes a shank, a frame, and a canopy in covering relationship to the frame wherein the canopy includes a main section and a rearward extending section, and the frame includes a plurality of rearward extending first rib sections. The umbrella being open is adapted to provide a wider protection area to an object carried on the shoulder or towed by the hand against the rain. The umbrella frame is made of FRP so as to reduce weight significantly.
Abstract:
A lock mechanism mounted in a large umbrella includes a sliding sleeve including an aperture on surface of a lower extension, a telescopic shank including a lower tube fixed in a handle and a sliding upper tube, a lock device disposed in the upper tube such that disposing a resilient projection of the lock device through holes of the tubes may fasten the shank, an actuation assembly for receiving the extension and including a transverse opening and a spring biased actuation member having a portion disposed in the aperture for locking the extension in a closed position of the umbrella, the actuation member including a trigger, and a spring biased rib fixing assembly disposed between the handle and the actuation assembly. Pushing the trigger will disengage the portion with the aperture to open the umbrella. Operating the lock device will effect a subsequent multi-sectional length adjustment of the shank.

Abstract:
One embodiment of a beach umbrella comprises a telescopic shank and a folding radial frame including ribs each including a first segment, a second segment, and a hinge pivotably interconnecting the segments, and spreaders each having one end pivotably connected to the first segment and the other end pivotably connected to a ring on the shank. The segments are substantially parallel in response to folding the hinges. The shank includes an upper support tube, a lower sliding tube adapted to slide in the support tube, and a rotatable locking device fixedly provided on a top of the sliding tube. The sliding tube is adapted to manually raise or lower to a plurality of vertical positions relative to the support tube, and the sliding tube is adapted to be locked in a selected one of the vertical positions.
Abstract:
A coupling device for securing one of a plurality of links to one of a plurality of spreaders of an umbrella is provided. The umbrella further includes lower and upper rings on its shank. The device comprises a sleeve fixedly put on a portion of the spreader, and a yoke-like member extended downwardly, the yoke-like member including a stop at an inner end, a transverse pin at an outer end, and a cavity between the stop and the pin wherein a flexible outer hook end of the link is inserted into the cavity to couple to the pin. Thus, force exerted by, will not remove the outer hook end of the link from the pin.
Abstract:
An enhanced frame of an auto-opening umbrella comprises hollow cylindrical intermediate joints with spreaders passed through and each including two spaced bottom lugs, a bar across the lugs, and a recess between the lugs. The bar is disposed less than half of a projected distance of the lug. A plurality of links has hooked ends pivotably coupled to a lower ring and the bar. Also, the recess is in communication with a hole of the joint. The outer hooked end of each link is sufficiently smaller than the recess so that ribs are spaced apart from the spreaders by a much smaller distance when the umbrella is folded. This can achieve a smooth folding operation and a more compact umbrella after folded.
