Abstract

(57) [Summary] [Purpose] The purpose is to provide an automatically opening/closing folding umbrella that prevents the umbrella from automatically opening when not intended. [Structure] A folding umbrella that is an automatic opening/closing type umbrella and has a multi-contractable umbrella shaft that gradually increases in diameter from the handle side toward the stone end. ) and umbrella shaft (40)
It is characterized by the provision of a safety device consisting of a cylindrical body (1) inserted between the two.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention is an automatic opening/closing type, and the diameter increases gradually from the handle side toward the stone end. This invention relates to a folding umbrella having a heavily contracted umbrella shaft.

0002

[Conventional technology]

The conventional folding umbrella mentioned above has a bottom wheel (10) and an umbrella shaft, as shown in Figure 1. There is a gap (50) between (40) and (40). The reason is that the umbrella shaft gradually moves upward. It has a large diameter, so the inner diameter of the lower wheel (10) is larger than the large diameter part (20). Otherwise, it cannot be opened completely.

0003

[Problem that the idea aims to solve]

In conventional umbrellas such as those described above, normal operation involves pressing the push button (30 a) to the left ( (as seen in Figure 1), it will move around the pivot pin below the push button (30 a). The repellent (60) is pushed to the left, and the tip of the repellent (60) is pulled to the left from the opening (70). The lower wheel (10) is automatically pushed upwards by the force of the spring. It will open. However, since there is the gap (50) mentioned above, the position of the bottom wheel (10) is The position is not stable, and the lower wheel (10) moves to the right (as seen in Figure 1) due to some shock. There is a risk that the umbrella may open automatically unexpectedly. This invention is based on The aim is to eliminate the drawbacks mentioned above.

0004

[Means to solve the problem]

The above-mentioned problem is that the automatic opening/closing type umbrella gradually increases in diameter from the handle side toward the stone end. In a folding umbrella with a multi-contractable umbrella shaft, A safety device consisting of a cylindrical body inserted between the lower wheel and the umbrella shaft at the end of the handle on the stone side. This problem is solved by the automatic opening/closing folding umbrella described above.

【Example】 FIG. 2 is an exploded perspective view of an embodiment of the present invention, and FIG. 3 is a sectional view. Reference number (30) is the handle, (30 a) is the push button, (10) is the lower wheel, and (60) is the hatchet below it. It is pivoted to the handle (30). The tip of the Hajiki (60) faces the opening (70) of the bottom wheel. , the lower wheel (10) is locked (Fig. 3). Reference number (1) is the potter's wheel (10) The cylinder is inserted into the gap (50) between the umbrella shaft (40) and the umbrella shaft (40). This cylinder (1 ), the lower wheel (10) is stabilized against the umbrella shaft (40), and the Hajiki (60) is This eliminates the risk of it falling out of the opening (70).

[0006]

[Effect of the idea]

Since the present invention has the above-described structure and function, it prevents the risk of the umbrella opening unintentionally. It can be prevented.
