Abstract

PROBLEM TO BE SOLVED: To safely and easily open and close an umbrella of a manually opening/closing type by avoiding providing a finger stopper projecting outward in the neighborhood of the runner side of a pressurizing part, but providing a ring- formed safety cover surrounding an outer peripheral face of the side of the runner and arranging a pressurizing part and the finger stopper at the safety cover. SOLUTION: This lower runner 1 consists of a main body part 10 and a runner part 11. The part 10 is a nearly cylindrical member and provided with vertical slits 100 on the side of its lower end. The slit 100 is provided with a pressurizing part 101 extending downward at an upper end edge and the part 11 is arranged to project like a disk from the middle of the part 10. Plural stretcher holding grooves 110 to which one end with a wire insertion hole is respectively inserted are provided on the outer peripheral surface of the part 11. The finger stopper 112 is arranged projecting outward along the lower side edge of the part 11 over the part 101 and the lower runner 1 is freely movably arranged along a metal rod.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention particularly relates to a hand-held umbrella that can protect a user's finger when opening and closing.

[0002]

2. Description of the Related Art Some manually-operated umbrella lower wheels have a slit provided on a shaft of the umbrella for letting a cissing on and out. When opening and closing the manually openable umbrella having the lower wheel, press the head of the repellent that protrudes from this slit to unlock the lower wheel,
Slide the lower wheel. However, since this repellent sheet is thin, when directly pressed with a finger, there is a problem that the repelling bites into the finger, making it difficult to press, and causing a pain in the finger. Therefore, as shown in FIGS. 18 to 22,
There is a potter's wheel that overhangs the slit and is provided with a pressing portion so as to press the head of the repellent projecting from the slit.

[0003] In some cases, the lower wheel can be locked without using repelling. Fig. 2
As shown in FIG. 3, the lower end of the slit is tiltably supported in the direction of the umbrella axis by a spring so that the lower end of the slit can bite into a recess provided in the umbrella axis, and the lower end of the slit is inclined by a spring. The pressing portion is urged so as to press the upper end side of the pressing portion to release the lock of the lower wheel and perform the opening and closing operation. In this specification,
The upper side indicates the side of the umbrella's stone, and the lower side indicates the handle side.

[0004] However, even when the umbrella is provided with the lower wheel having the pressing portion as described above, the lower umbrella must be firmly grasped when the umbrella is opened so that the finger does not slide, and it is difficult to open the umbrella. There was a problem. In addition, this umbrella can open and close the umbrella more safely than the conventional umbrella of the type that directly presses a repellent, but there was a problem that a finger was caught in the skeleton during the opening and closing operation, etc. .

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to make it possible to safely and easily open and close a manually-openable umbrella.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a substantially cylindrical main body having a pressing portion which is pressed to unlock the umbrella when the umbrella is opened and closed, and a disk-shaped member extending outward from the main body. This is achieved by providing a finger stopper protruding outwardly in the vicinity of the lathe portion side of the pressing portion in the lower lathe comprising the protruding lathe portion. In addition, this is achieved by providing a ring-shaped safety cover surrounding the outer peripheral surface of the potter's wheel portion without hindering rotation of the support bone, and providing a pressing portion and a finger stopper on the safety cover.
