Abstract
A slim safety umbrella runner includes a push button having a pivotal portion formed on a bottom portion of the push button and insertably engaged in a pivotal cavity formed in a bottom rim of the runner, with the push button pivotally biasing a resilient protrusion resiliently formed on a runner sleeve of an umbrella central shaft, whereby upon a depression of the push button to disengage the runner from the resilient protrusion, the runner will be lowered for closing the runner.
Claims6
An umbrella comprising:
- a central shaft having a runner sleeve formed on said shaft;
- a runner having a cylinder portion slidably engaging with said runner sleeve;
- a ferrule formed on the cylinder portion for pivotally securing a stretcher rib of a rib assembly which is pivotally secured to an upper notch formed on a top of said runner sleeve and of said central shaft;
- a socket formed in said runner and operatively engaged with a resilient protrusion formed on said runner sleeve for opening the umbrella;
- and
- a push button insertably pivotally secured to said runner, said push button including a pivotal portion formed on a bottom portion of the push button and insertably secured to a pivotal cavity formed in a bottom rim generally ring shaped of the runner;
- and a limiting projection formed on a top of the push button and slidably movably held in a slot recessed in a lower portion of the ferrule of the runner;
- whereby upon a depression of the push button to pivotally bias the push button to inwardly depress the resilient protrusion to disengage the socket in the runner from the resilient protrusion, the runner will be lowered for closing the umbrella.
A multiple-fold umbrella comprising a central shaft having a runner sleeve formed on said central shaft and a resilient protrusion formed on said runner sleeve;
- a rib assembly respectively pivotally secured to an upper notch formed on a top of said central shaft and pivotally secured to a safety runner slidably held on said runner sleeve;
- said runner having a socket recessed therein for engaging said resilient protrusion on said runner sleeve when opening the umbrella;
- and said runner including a push button insertably pivotally secured to said runner;
- said rib assembly including a spring rib pivotally connected between a top rib and a tail rib, said spring rib having a U-shaped loon formed on a middle rib portion of said spring rib for slidably coupling said U-shaped loop of said spring rib to an intermediate rib pivotally connected between said tail rib and said top rib, and said top rib pivotally secured to a stretcher rib which is pivotally connected to said runner;
- and said push button including a pivotal portion formed on a bottom portion of the push button and insertably secured to a pivotal cavity formed in a bottom rim generally ring shaped of the runner;
- and a limiting projection formed on a top of the push button and slidably movably held in a slot recessed in a lower portion of the ferrule of the runner;
- whereby upon a depression of the push button to pivotally bias the push button to inwardly depress the resilient protrusion to disengage the socket in the runner from the resilient protrusion, the runner will be lowered for closing the umbrella.
