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 biased as described above, and the upper end of the pressing portion is pressed to release the lock of the lower wheel and to perform the opening / 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 lower cylinder comprising a substantially cylindrical main body movably provided along an umbrella axis, and a lathe section protruding outward from the main body in a disk shape. On a potter's wheel, a pressing portion pressed to release a lock of the lower wheel when opening and closing the umbrella, and a finger stopper protruding outward from an outer peripheral surface of the potter's wheel near the potter's wheel side of the pressing portion are provided. This is achieved by:
Further, a ring-shaped safety cover surrounding the outer peripheral surface of the potter's wheel may be provided without hindering the rotation of the support bone, and the pressing portion and the finger stopper may be provided on the safety cover. Furthermore, the above-mentioned object is. In a lower wheel comprising a substantially cylindrical main portion movably provided along an umbrella shaft and a wheel portion protruding outward from the main portion in a disk shape, both ends of the wheel portion are cut into substantially semicircular shapes. Long board
When this semi-circular part is used as a finger stopper,
In addition, this can also be achieved by providing a pressing portion below the umbrella, which is pressed to release the lock of the lower wheel when the umbrella is opened and closed. Also in this case, a ring-shaped safety cover surrounding the outer peripheral surface of the potter's wheel may be provided without hindering rotation of the support bone, and the pressing portion may be provided on the safety cover.

2 is a partition. As shown in FIG. 12, the configuration of the main body 40 is the same as that of the lower part shown in the first embodiment except that the pressing portion and the finger stopper are removed.

As shown in FIG. 13, the safety cover 41 is a ring-shaped member, and the pressing portion 410 is provided so as to extend downward from a part of the lower edge of the member, and the finger stopper 411 is connected to the pressing portion. It is provided near the base of 410.
In addition, a partition wall 412 is provided along the upper edge of the member so that the partition wall 412 is cut so as not to hinder the rotation of the supporting bone when assembled. This safety cover 41
As shown in (1), the partition wall 412 is fitted on the main body 40 and covers the outer peripheral surface of the potter's wheel portion 402.

When the umbrella provided with the lower wheel 4 is opened, the lock of the lower wheel 4 is released, and as shown in FIG.
As described above, the lower wheel 4 is pinched so that the thumb hits the finger stopper 411, and the lower wheel 4 is pushed upward.
Conversely, when closing, as shown in FIG. 15, the pressing portion 410 is pressed to unlock the lower wheel 4, and the lower wheel 4 is pulled down. In this embodiment, in addition to the operation and effect similar to those of the above-described embodiment, since the partition wall 412 covers the annular groove 404, the end of the wire supporting the support bone is
This eliminates the risk of injury to the fingers and improves the appearance.

Next, FIG. 16 will be described. FIG.
Inside, 5 is the potter's wheel, 50 is the main part, 500 is the slit,
Reference numeral 501 denotes a pressing portion, 51 denotes a potter's wheel portion, 510 denotes a support bone holding groove, and 511 denotes an annular groove. The main configuration of the lower wheel 5 is the same as that of the first embodiment, and therefore the description will focus on the differences. The potter's wheel part 51 of the lower potter's wheel 5 is formed in a long disk shape with both ends cut in a substantially semicircular shape as shown in the figure.
This semicircular part is used as a finger stopper and
, A pressing portion 501 is provided below the semicircle.
The shape portion protrudes outward from the other portions, and the lower surface thereof functions as a finger stopper. In this embodiment, since finger stoppers are formed on both sides of the main body 50, the fingers can be very easily and safely opened and closed without the fingers being pinched on the trabecular bone during the opening and closing operation of the umbrella.

Next, FIG. 17 will be described. In FIG.
