Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to an improvement of a folding western umbrella.

[Conventional technology]

Conventionally, folding western umbrellas have been constructed so that the middle rod is extendable and the frame is bendable so that the umbrella can be folded compactly when closed.

That is, as shown in FIG. 8, the middle rod 1 is made up of multiple stages of nested pipes 2 and 3 of different diameters, and has a first reel 4 that releasably locks both pipes 2 and 3 in the extended position. Be prepared. An upper potter's wheel 5 is fixed to the tip of the middle rod 1, and a handle 6 is fixed to the lower end. A lower potter's wheel 7 is slidably inserted into the middle rod 1,
The lower potter's wheel 7 is formed into a cylindrical body having a shaft hole 8 that is inserted into the center rod, and is located above the large diameter pipe 2 when the umbrella is closed, and above the small diameter pipe 3 when the umbrella is opened.
In addition, the lower potter's wheel 7 is connected to the first repellent wheel 4 when the umbrella is closed.
When the umbrella is opened, the small diameter pipe 3
It is removably locked to a second repellent 9 provided in the.

[The problem that the idea attempts to solve]

In the above-mentioned conventional folding umbrella, the lower potter's wheel 7 is
The inner diameter of the shaft hole 8 is set to be the same as or slightly larger than the outer diameter of the large diameter pipe 2 because it slides so that it is located above the large diameter pipe 2 when the umbrella is closed and above the small diameter pipe 3 when the umbrella is opened. It is formed. Therefore, the lower potter's wheel 7 is stably held on the large diameter pipe 2 when the umbrella is closed, but is not stable on the small diameter pipe 3 when the umbrella is opened. That is, as shown in FIG. 9, since the shaft hole 8 of the lower potter's wheel 7 has a considerably larger diameter than the small diameter pipe 3 and has a large play space, the lower potter's wheel 7 has a large play space with respect to the axis of the small diameter pipe 3. The axis is tilted at an angle θ. As a result, when the umbrella is opened, the frame as a whole is tilted and deviated from the axis of the center rod 1, which not only impairs the aesthetic appearance of the umbrella cloth, but also causes the lower potter's wheel 7 to wobble through the play space when exposed to wind and rain. There is a problem in that the frame moves loosely along with the umbrella cloth.

[Means for solving problems]

The present invention solves the above problems and provides a folding western umbrella.

Therefore, the means of the present invention includes a telescopic middle rod consisting of a plurality of stages of nested pipes of different diameters; an upper potter's wheel fixed to the tip of the middle rod; It is formed into a cylindrical body with an inner diameter that is fitted onto the pipe, and a lower potter's wheel is extendably fitted onto the middle rod so that it is positioned above the large diameter pipe when the umbrella is closed and above the small diameter pipe when the umbrella is opened. In a folding umbrella equipped with: on a small diameter pipe corresponding to the opening position of the lower wheel, there is a cylindrical shape having an outer diameter larger than the outer diameter of the small diameter pipe and smaller than the inner diameter of the lower wheel. A large-diameter holding part is provided, and the inner diameter of the large-diameter holding part is made to approximately match the outer diameter of the small-diameter pipe, and the outer diameter of the large-diameter holding part is made to be approximately matched to the inner diameter of the lower potter's wheel, so that when the umbrella is opened, the lower The point is that the potter's wheel is configured to be inserted into the large diameter holding part.

It is most preferable that the large-diameter holding portion has an outer diameter that substantially matches the inner diameter of the lower potter's wheel.

Moreover, in the folding umbrella of the present invention having the above structure, the lower part of the middle rod extending from the lower potter's wheel to the hand when the umbrella is closed can be configured with a plurality of stages of telescoping telescopic bodies. At this time, a portion of the telescoping telescopic body can constitute a hand.

〔Example〕

An embodiment of the present invention will be described in detail below based on the drawings.

(First Embodiment) In the first embodiment shown in FIGS. 1 to 4, the middle rod 10 that constitutes the entire shaft of the western umbrella is
It is composed of a plurality of stages of nested pipes 11 and 12 of different diameters, and is provided with a first reel 13 that releasably locks both pipes 11 and 12 in an extended state. An upper potter's wheel 14 is fixed to the tip of the middle rod 10, and a handle 15 is fixed to the lower end. A lower potter's wheel 16 is slidably inserted into the middle rod 10, and the lower potter's wheel 16
is formed into a cylindrical body having a shaft hole 17 that is inserted into the large-diameter pipe 11 of the middle rod 10, and is located above the large-diameter pipe 11 when the umbrella is closed, and is located on the small-diameter pipe 12 when the umbrella is closed.
located above. The lower potter's wheel 16 is removably engaged with the first repellent 13 when the umbrella is closed, and is removably engaged with the second repellent 18 provided on the small diameter pipe 12 when the umbrella is opened. These configurations are similar to the conventional example described above.

As the framework structure of the Western umbrella, the framework structure of a conventionally known folding Western umbrella can be adopted, and includes a strut 19 pivotally attached to the lower potter's wheel 16, and a main rib linked to the strut 19 and the upper potter's wheel 14. 20, and a small bone 21 which is pivotably attached to the tip of the main rib 20 so as to be freely reversible. The illustrated example shows a frame of a normal folding umbrella in which the middle part of the main rib 20 is pivotally connected to the tip of the support rib 19, and the base end of the main rib 20 is directly pivotally connected to the upper potter's wheel 14. It may also be a framework in which the main rib 20 is indirectly linked to the upper potter's wheel 14 via other bones, such as what is called a Western umbrella.

In the above configuration, in the present invention, the lower wheel 1
On the small diameter pipe 12 corresponding to the opening position of 6, there is a lower potter's wheel 1 larger than the outer diameter of the small diameter pipe 12.
A cylindrical large-diameter holding part 22 having an outer diameter smaller than the inner diameter of the pipe 6 is provided, and the inner diameter of the large-diameter holding part 22 is made to approximately match the outer diameter of the small-diameter pipe 12. The outer diameter of 22 is made to approximately match the inner diameter of the lower wheel 16. In this example, the fourth
As shown in the figure, the large-diameter holding portion 22 is integrally molded with the upper potter's wheel 14 from synthetic resin, and the large-diameter holding portion 22
is extrapolated onto the small diameter pipe 12. Since the upper wheel 14 is fixed to the small diameter pipe 12 via a pin or the like, the large diameter holding portion 22 is also fixed to the small diameter pipe 12. Alternatively, the large-diameter holding portion 22 may be formed separately from the upper potter's wheel 14, inserted onto the small-diameter pipe 12, and fixed with a pin or the like. In this case, the large-diameter holding part 22 can be formed by cutting a pipe made of the same material as the large-diameter pipe 11 to a predetermined length, and the outer diameter of the large-diameter holding part 22 is the same as the outer diameter of the large-diameter pipe 11. They can be configured to have the same diameter. In this embodiment, the large-diameter holding portion 22 is formed to have a length that approximately corresponds to the upper sleeve 16a of the lower potter's wheel 16 when the umbrella is opened.

According to this first embodiment, as shown in FIG. 4, when the lower potter's wheel 16 is opened, the shaft hole 17 is inserted into the large-diameter holding part 22 and is stably held. The lower potter's wheel 16 does not tilt with respect to the small diameter pipe 12 of the middle rod 10. In addition, when folding the western umbrella, from the closed state shown in the second figure,
is inverted in a bent manner with respect to the main rib 20, and further,
The large diameter pipe 11 may be slid onto the small diameter pipe 12 while pushing the first repellent 13 to contract the middle rod 10, and as a result, as shown in the third figure, the hand 15
is located near the lower potter's wheel 16 in the closed state, and also near the pivoting portion 23 of the bent main rib 20 and small bones 21, so that a predetermined folded state is obtained.

(Second Embodiment) In the second embodiment shown in Figs.
The length is such that it can be extrapolated over the entire length. That is, compared to the large-diameter holding portion 22 of the first embodiment, it is formed longer by a portion corresponding to the dimension L in FIG. Therefore, when opening the umbrella, the lower potter's wheel 16
The entire length in the axial direction is held by the large-diameter holding portion 22 and is stabilized.

However, if the large-diameter holding part 22 is formed longer than that of the first embodiment as described above, the middle rod 10 will be in a contracted state by sliding on the small-diameter pipe 12 of the large-diameter pipe 11 when the umbrella is closed. So, large diameter pipe 11
As a result, as shown in FIG.
5 and a large diameter pipe 11 corresponding to the above-mentioned dimension L.
will remain. That is, the large-diameter pipe 11 and the handle 15 protrude long below the lower wheel 16 and the pivot portion 23, making it impossible to obtain a predetermined folded state of the umbrella.

For this reason, in this second embodiment, a plurality of stages of telescoping telescopic bodies 24 are constructed at the lower part of the middle rod extending from the lower potter's wheel 16 to the tail end of the handle 15 when the umbrella is closed.
In the case of the illustrated example, the tail end 24a of the large diameter pipe 11,
A two-stage telescopic body 24 is constructed by the cylinder body 24b that allows insertion of the cylinder body 24b, and the cylinder body 24b
5, but it is also possible to configure it with three or more stages. Although not shown, it is preferable that the extensible bodies 24a and 24b are releasably locked to each other in the extended state and/or contracted state by a locking means. As a result, the elastic body 24
If you contract it, as shown in Figure 7, the hand 15
is located near the lower potter's wheel 16 when the umbrella is closed, making it possible to obtain a predetermined folded state.

The rest of the structure is the same as that of the first embodiment, and the same parts are designated by the same reference numerals.

As a result of the above-described configuration, the present invention has the following effects.

According to the present invention described in claim 1 of the utility model registration, a multi-stage nested pipe of different diameters 1
In a folding western umbrella equipped with a telescopic middle rod 10 consisting of 1 and 12, the small diameter pipe 12 is provided with a large diameter holding part 22 that allows the lower potter's wheel 16 to be inserted and stably held when the umbrella is opened. There is no possibility of tilt deviation or movement of the lower potter's wheel.

According to the present invention as set forth in claim 2 of the utility model registration, by providing the large-diameter holding portion 22, the inner rod 10 may not be able to contract to a predetermined folded state due to the design. Also, a predetermined compact folded state can be obtained by contracting the lower middle rod lower part of the lower potter's wheel 16 when the umbrella is closed.

According to the present invention as set forth in claim 3 of the utility model registration, the extendable body 24 of the lower part of the center rod can be constructed using the handle 15, thereby ensuring compactness and aesthetics when folded. It becomes possible to maintain the
