DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an umbrella that can be safely opened and closed.

[0002]

2. Description of the Related Art A lower wheel of an umbrella is slidably mounted on an umbrella shaft, and is normally projected and pressed on the umbrella shaft to be locked by a cissing provided to be immersed in the umbrella shaft. It is held in the open position. At this time,
Since the lower wheel is under tension to move in the direction of the umbrella handle, the umbrella can be closed by pushing the cissing into the umbrella shaft to release the lock. However, in the conventional lower wheel, the end on the umbrella handle side is a large-diameter bulging portion that bulges outward and is thick, so when closing the umbrella, only the cissing must be pushed in. The lock could not be released, and as soon as the lock was released, the lower wheel slid vigorously toward the umbrella handle and the finger pressing the stopper was pinched between the umbrella shaft and the lower wheel, which was dangerous. In addition, the umbrella bone locked on the lower wheel is tiltably locked via a wire held at one end by a wheel portion formed on the outer peripheral surface of the lower wheel. Are twisted at both ends. The twisted part of this wire is sharp and dangerous at the tip, and when trying to grab the potter's wheel, it accidentally cuts a finger, or clothes gets stuck, torn or frayed,
In addition, there is a problem that the user is injured by mistake during repair.
