Abstract
A safety umbrella includes: a lower runner for pivotally connecting the ribs of the umbrella slidably held on a central shaft of the umbrella and formed with a latch hole in the lower runner; a controller formed in a grip of the central shaft having a push button normally protruding outwardly from the grip, and a latch connectable with the push button and resiliently urged by a restoring spring retained in the grip for operatively engaging the latch hole in the lower runner for locking the lower runner and the ribs at a folded condition, to thereby eliminate a long slot cut in the shaft above the grip to prevent deformation or damage of the shaft and to eliminate the acute spring catch formed in the shaft to prevent injury to the umbrella user as stuck by the conventional spring catch.
Claims1
A safety umbrella comprising:
- a central shaft having a grip formed on a hollow lower tube of the central shaft, said grip having a central hole formed in an upper central portion of said grip;
- a rib means for securing an umbrella cloth thereon having a runner of the rib means slidably held on said central shaft;
- and
- a control means formed in the grip for controlling the opening or closing of the umbrella;
- the improvement which comprises:
- said runner including an extending sleeve protruding downwardly from said runner having a latch hole formed in the extending sleeve;
- and
- said control means including:
- a push button slidably held in a button hole transversely formed in the grip adjacent to a first side of the grip;
- a latch resiliently held in said lower tube of the central shaft to normally resiliently protrude outwardly through an inner latch hole formed in the lower tube to be confined in the central hole within the grip towards the second side of the grip opposite to the first side of the grip;
- a restoring spring resiliently retained in the lower tube for normally urging the latch outwardly for engaging the latch hole formed in the extending sleeve of the lower runner when folding the umbrella by lowering the extending sleeve of the lower runner into the central hole of the grip;
- and a transmission member seesawly pivotally mounted in the lower tube by a pivot having a depression end formed on a lower end of the transmission member and protruding towards the first side of the grip to be opposite to the latch end and to be normally contacted with the push button, and having a latch end formed on an upper end of the transmission member to connect the latch, with the latch and the latch end of the transmission member normally resiliently urged by the restoring spring to protrude the latch outwardly towards the second side of the grip and to seesawly bias the depression end formed on the lower end of the transmission member outwardly towards the first side of the grip to simultaneously urge the push button outwardly beyond the button hole of the grip, ready for a depression by an umbrella user for opening the umbrella from a folded or closed umbrella.
