DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention This invention is intended to make it possible to increase the length of an umbrella handle for stretchable folding umbrellas and parasols, especially in the extended state as compared with the shortened state. It relates to a multi-stage retractable umbrella handle.

2. Description of the Related Art Umbrella patterns that can be expanded and contracted in four steps are disclosed in Japanese Utility Model Publication Nos. 57-46815 and 57-46816.

As illustrated in FIGS. 6 and 7, the umbrella handles disclosed in these publications have a first umbrella handle tube 1, a second umbrella handle tube 2, a third umbrella handle tube 3 and a fourth umbrella handle tube 3 and a fourth umbrella handle tube whose diameters are sequentially increased. The umbrella handle tube 4 is telescopically fitted so as to be able to extend and contract, and is an umbrella handle configured to be capable of expanding and contracting in four stages. In the opened umbrella state, the locking portion 5a at the upper end is projected outward from the window hole 1a of the first umbrella handle tube 1 to the locking piece 5 for locking the sliding wheel 6, While forming the projection 5b on the opposite side, the other window hole 1b into which the projection 5b is fitted in the umbrella handle shortened state is provided with the first umbrella handle tube 1 on the opposite side of the window hole 1a.
In addition, the upper end of the second umbrella handle tube 2 is set to be located above the engaging portion 5a of the engaging piece 5 in the extended state of the umbrella handle, and In the umbrella handle extended state, a window hole 2a is formed so as to overlap with the window hole 1a for protruding the locking portion.

In the umbrella handle shown in FIGS. 6 and 7, the upper end portion of the locking piece 5 is engaged with the inner surface of the second umbrella handle tube 2 as disclosed in Japanese Utility Model Publication No. 57-46816. An engaging projection 5c that restricts the amount of projection of the stop piece 5 is integrally provided. In FIG.
7 is a fixing portion of the locking piece 5 to the first umbrella handle tube 1, 8 is a first
It is an upper wheel fixed to the upper end of the umbrella handle tube 1.

In the structure in which the four umbrella handle tubes 1-4 fitted as described above are provided, the sliding lock 6 which is pulled down to the fourth umbrella handle tube 4 having the largest diameter on the umbrella handle has a considerably large diameter. Since the smallest diameter first umbrella handle tube 1 has a considerably small diameter, a large clearance exists between the first umbrella handle tube 1 and the sliding wheel 6 in the open state. On the other hand, in the umbrella handle illustrated in FIGS. 6 and 7, in the opened umbrella state in which the sliding lock 6 is pushed up on the umbrella handle extended as shown in FIG. The upper end is located above the locking piece locking portion 5a, and the clearance on the inner surface side of the sliding wheel 6 is from the clearance α between the sliding wheel 6 and the first umbrella handle tube 1 to the sliding wheel 6
Since the clearance β between the sliding lock 6 and the second umbrella handle tube 2 is reduced at the lower end of the sliding lock 6, the sliding lock 6 is disengaged from the locking portion 5a or locking by the locking portion 5a is unstable. As described above, the protrusion 5b is provided on the locking piece 5 and the other window hole 1b into which the protrusion 5b is fitted in the umbrella handle shortened state is provided. Since the width of the upper end portion of the locking piece 5 is increased by forming it on the first umbrella handle tube 1, the protrusion 5b remains in the umbrella handle in the open state shown in FIG. The stopper portion 5a can be largely projected outside the umbrella handle, and the sliding wheel 6 can be reliably and stably locked.

Problems to be Solved by the Invention In the four-step retractable umbrella handle shown in FIGS. 6 and 7, the upper end of the second umbrella handle tube 2 is located above the locking piece locking portion 5a in the umbrella handle extended state. Since the lower half part of the first umbrella handle tube 1 is positioned so as to be largely left in the second umbrella handle tube 2, the extension amount of the first umbrella handle tube 1, and hence the umbrella handle length in the extended state. There are still limits. Even if it is a normal rain umbrella, there is no resistance, but if it is a parasol that also serves as a rain umbrella for women, it feels comfortable when using it as a parasol because the umbrella pattern is short.

In view of this, the present invention is capable of doubling the extension amount of the uppermost umbrella handle tube as compared with the conventional one as shown in FIGS. 6 and 7, and increasing the umbrella handle length in the extended state. The purpose is to provide an umbrella pattern.

Technical measures taken to solve the problem. Therefore, as shown in FIG. 1-5, the present invention has a plurality of umbrella-handle tubes 1, 2, 3, whose diameters are gradually increased from the upper stage to the lower stage. 4 was telescopically fitted in a telescopic manner, and the following technical measures were taken in an umbrella handle configured to be able to expand and contract in multiple stages.

That is, the upper end of the umbrella handle tube 1 is fixed to the upper handle tube 1 and the upper locking portion 5a is projected outward from the window hole 1a of the uppermost handle tube 1 in the opened state. In the uppermost umbrella handle tube 1 above the locking piece 5 that locks the sliding wheel 6, the biasing piece 10 made of a leaf spring or an elastic wire supported by the umbrella handle tube 1 is supported.
And another window hole 1c that allows the biasing projection 10a provided on the biasing piece 10 to project outside the uppermost umbrella handle tube 1 is provided on the uppermost umbrella handle tube 1 on the opposite side of the window hole 1a. It is configured so that the sliding roller 6 is urged to move in the direction opposite to the protruding direction of the locking piece 5a of the locking piece 5 by the urging piece 10 in the opened state.

In the example of FIGS. 1-3, the urging piece 10 is made of a leaf spring, and in the example of FIGS. 4 and 5, the urging piece 10 is made of a wire. The illustrated embodiment relates to an example in which the invention is implemented as a four-step retractable umbrella handle, but the invention can also be implemented as a three-step or five-step retractable umbrella handle.
