Embodiment Construction

[0019] Referring to FIGS. 1 to 5, a coupling member 24 for coupling a link 23 to a spreader 21 of umbrella constructed in accordance with the invention is illustrated. As shown, a lower ring 11 including a plurality of equally spaced apart slits 111, an upper ring 12 including a plurality of equally spaced apart slits 121, and a spring 13 compressed between the lower and upper rings 11 and 12 are provided on an upright shank 10. A plurality of spreaders 21 are pivotably connected between the upper ring 12 and a plurality of radial ribs 22. Each of a plurality of metal links 23 has a flexible inner hook end 231 pivotably connected to the slit 111. A plurality of ribs 22 each includes a coupling element 221 at a portion other than both ends thereof. The coupling element 221 has a yoke 222 extended from its underside. A plurality of spreaders 21 each has an inner end pivotably connected to the slit 121 and an outer end 25 pivotably connected to the yoke 222. A plurality of coupling mem...

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.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to umbrella frame and more particularly to an improved device for securing a link to a spreader of an umbrella. [0003] 2. Description of Related Art [0004] Umbrellas or parasols are personal articles for the protection of rain or sun. However, conventional umbrellas are not durable due to, in most cases, weak pivotal means of connecting one component to the other component. A portion of a conventional umbrella frame is shown in FIGS. 7, 7A, and 8. As shown, a lower ring 91, an upper ring 92, and a spring 93 compressed between the lower ring 91 and the upper ring 92 are provided on an upright shank 90. A plurality of spreaders 94 are pivotably connected between the upper ring 92 and a plurality of radial ribs 95. A plurality of links 96 are pivotably connected between the lower ring 91 and the radial spreaders 94. In detail, the link 96 has an outer hook end 98 pivotably connected to a t...
