Multiple-fold automatic umbrella with simplified control means
First Claim
1. An automatic umbrella comprising:
- a central shaft means including;
an inner tube, a grip secured with the inner tube, a middle tube slidably held on an outer and upper side of the inner tube, an outer tube slidably held on an outer and upper side of the middle tube, an upper notch secured on a top portion of the outer tube, and a central sleeve set having an inner and outer sleeve section telescopically held within said inner, middle and outer tubes;
a rib assembly including a plurality of ribs pivotally connected with one another and pivotally secured between the upper notch and a lower runner slidably held on said central shaft means;
an opening spring for opening an umbrella retained in said central shaft means and slidably disposed about the central sleeve set;
a plurality of closing springs respectively secured on said rib assembly for operatively closing an umbrella from an opened state by an elastic energy stored when opening the umbrella; and
a control means including;
a push button resiliently held in the grip, an upper latch slidably held in a slotted plate perpendicularly protruding from a middle button portion of the push button from a first side of the central shaft means towards a second side of the shaft means and operatively depressed by the push button for opening the umbrella, a closing controller having a lower latch resiliently held in the grip and operatively depressible by the push button for inwardly pushing a locking head, which is secured with a drag rod coupled to a drag rope which is linked through the lower runner to an upper portion of the outer tube, for disengaging the locking head from a detent protrusion formed in a lower portion of the inner tube, thereby allowing each said closing spring to be restored to release a pre-stored elastic energy for closing the umbrella from an opened state, with the lower latch resiliently secured to an anti-false operation safety means which is lowered by the outer and middle tubes when closing the umbrella to prevent a false depression of the closing controller as depressed by the push button.

Abstract
A multiple-fold automatic umbrella includes: a control device having a push button slidably held in the grip for controlling the opening and closing of the umbrella, an opening controller of the control device formed as a sliding plate transversely slidably mounted in a middle portion of of push button for opening the umbrella from a closed state of the umbrella; and a closing controller of the control device having a lower latch contiguous to a middle portion of the push button to be depressed by the push button for closing an opened umbrella, whereby upon a direct depression of the push button without considering an upper button portion or a lower button portion of the push button, an umbrella can be opened or closed conveniently and ergonomically, thereby simplifying the structure and operation of the control device of the automatic umbrella.

9. An automatic umbrella comprising:
-
a central shaft means including;
an inner tube, a grip secured with the inner tube, a middle tube slidably held on an outer and upper side of the inner tube, an outer tube slidably held on an outer and upper side of the middle tube, an upper notch secured on a top portion of the outer tube, and a central sleeve set having an inner and outer sleeve section telescopically held within said inner, middle and outer tubes;a rib assembly including a plurality of ribs pivotally connected with one another and pivotally secured between the upper notch and a lower runner slidably held on said central shaft means;
an opening spring for opening an umbrella retained in said central shaft means and slidably disposed about the central sleeve set;a plurality of closing springs respectively secured on said rib assembly for operatively closing an umbrella from an opened state by an elastic energy stored when opening the umbrella; and a control means including;
a push button resiliently held in the grip, an upper latch slidably held in a slotted plate perpendicularly protruding from a middle button portion of the push button from a first side of the central shaft means towards a second side of the shaft means and operatively depressed by the push button for opening the umbrella, a closing controller having a lower latch resiliently held in the grip and operatively depressible by the push button for inwardly pushing a locking head, which is secured with a drag rod coupled to a drag rope which is linked through the lower runner to an upper portion of the outer tube, for disengaging the locking head from a detent protrusion formed in a lower portion of the inner tube, for closing the umbrella from an opened state, and said lower latch including;
a pin secured at a base portion of the slotted plate of the push button for pivotally mounting the lower latch at a middle inside portion of the button, a latch restoring spring retained on the push button for normally levelling the lower latch to be generally perpendicular to the push button to allow an arcuate latch end formed at an inner free end of the lower latch to depress the locking head to be disengaged from the detent protrusion when closing the umbrella, said lower latch downwardly biased by each bottom tube end of the outer tube and middle tube when closing and resetting the umbrella for storing energy of the opening spring, thereby allowing an inward depression of the push button to open the umbrella.
