Multiple-fold automatic umbrella with simplified grip

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 telescopically held within said inner, middle and outer tubes;
• a rib assembly including a plurality of rib 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 pivotally mounted in the grip by a pivot and normally held in a button hole in the grip, an upper latch slidably held in an upper portion of the grip and operatively depressed by an upper button portion of the push button for opening the umbrella, a closing controller operatively depressible by a lower button portion of the push button for disengaging 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, from a lower latch slidably held in a lower portion of the grip, thereby allowing each said closing spring to be restored to release its pre-stored elastic energy for closing the umbrella from an opened state, and an anti-false operation safety means normally shielding the closing controller to prevent a false operation to depress the closing controller before fully opening the umbrella;
• the improvement which comprises:
• said upper latch including a depression portion formed on a first end portion of the upper latch adjacent to a first side of the central shaft means, an upper projection formed on a second end portion of the upper latch and protruding from a second side of the shaft means towards a central latch hole to be engageable with a lower hole formed in each said tube of the outer tube, the middle tube and the inner tube for locking an umbrella under a closed state, the central latch hole formed in a central portion of the upper latch for downwardly passing a lower tube portion of each said outer tube and middle tube when folding the central shaft means for closing the umbrella, and an upper spring socket formed in the second end portion of the upper latch for retaining an upper spring end of a restoring spring held in the grip adjacent to the second side of the shaft means to urge the upper latch outwardly towards the first side of the shaft means to be operatively depressed by the upper button portion of the push button for disengaging the upper projection from each said lower hole of the outer, middle and inner tubes for opening the umbrella as resiliently tensioned by the opening spring;
• and said closing controller including:
• a lower latch slidably held in a lower portion of the grip and having a lower projection protruding from a spring retaining portion of the lower latch towards the first side of the shaft means to be engageable with the locking head secured with the drag rod, a pair of arm members bifurcated from the lower projection and protruding towards the push button at a first side of the central shaft means to be operatively depressed by the lower button portion of the push button for closing an umbrella from an opened state, with the spring retaining portion secured with a lower spring end of the restoring spring adjacent to the second side of said shaft means for normally urging the lower latch outwardly to be operatively depressed by the lower button portion of the push button, and said anti-false operation safety means having a slot slidably engageable with said lower projection of said lower latch.
