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. 5, the middle rod 1 is made up of multiple stages of nested pipes 2 and 3 of different diameters, and has a first repellent 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 inserted into the middle 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 closed.
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. 6, 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 entire frame is tilted and deviated with respect to the axis of the center rod 1, which not only impairs the beauty 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 to solve the problem]

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

The means of the present invention includes an upper wheel fixed to the tip of the center rod, a cylindrical lower wheel slidably fitted onto the center rod, and a lower wheel attached to the lower wheel. It comprises a pivoted support bone, a main bone linked to the support bone on an upper potter's wheel, and a coronal bone rotatably pivoted to the tip of the main bone, and is located near the tip of the columbar bone when the umbrella is closed. In a folding Western umbrella with a handle arranged as follows: The middle rod is located corresponding to the lower end of the lower potter's wheel when the umbrella is being held, and is located corresponding to the pivot point between the main rib and the child's rib when the umbrella is closed. For part X, the upper part of the middle rod between the vicinity of the part The lower part of the center rod is constituted by a multi-stage telescoping body including the handle.

〔Example〕

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

As shown in FIGS. 1 to 3, the middle rod 10 that constitutes the entire shaft of the umbrella is located at a portion X, which will be described later.
The tip side is the middle rod upper part 11, the rear end side is the middle rod lower part 1
2, and an upper potter's wheel 13 is fixedly installed at the tip of the upper part 11 of the middle rod. The lower potter's wheel 14 is formed into a cylindrical body having a shaft hole 15 that is slidably inserted onto the upper part 11 of the middle rod. The upper part 11 of the center rod has a first reel 16 that removably locks the lower potter's wheel 14 in the closed position, and a second reel 17 that releasably locks the lower potter's wheel 14 in the open position. is provided.
Thus, over the entire length of the middle rod upper part 11, the outer diameter of the middle rod upper part 11 is formed to approximately match the inner diameter of the shaft hole 15 of the lower potter's wheel 14. For this reason, the lower wheel 14 is stably held with the shaft hole 15 adapted to the outer circumference of the upper middle rod 11 both when the umbrella is closed and when the umbrella is opened. is not tilted relative to the upper part 11 of the middle rod.

The frame structure of the Western umbrella is the same as that of a conventionally known folding Western umbrella, and includes a strut 18 pivotally attached to a lower potter's wheel 14,
The main rib 19 is linked to the support bone 18 and the upper potter's wheel 13, and the coronal bone 20 is rotatably pivoted to the tip of the main bone 19. In the illustrated example, the main rib 1
The middle part of 9 is pivotally connected to the tip of the support bone 18, and the main bone 1
This figure shows the framework of a normal folding umbrella in which the base end of the umbrella 9 is directly pivoted to the upper potter's wheel 13.
A skeleton may be indirectly linked to the bone via another bone.

The lower middle rod 12 is composed of multiple stages of telescoping telescopic bodies 21, 22, and 23. In the case of the illustrated embodiment, as shown in FIGS. 1 to 3, the first elastic body 21 is constituted by a pipe into which the tail end of the middle rod upper part 11 can be inserted, and the second elastic body 22 is constituted by a pipe into which the first telescopic body 21 can be inserted, and the third telescopic body 23 is constituted by a cylinder into which the second telescopic body 22 can be inserted. 23 constitutes a handle 24 of the western umbrella. At this time, although not shown, it is preferable that each of the extensible bodies 21, 22, and 23 be removably locked to each other in an extended state and/or a contracted state by a locking means. These first, second and third elastic bodies 21, 22, 23 are
In the extended state shown in FIG.
0 is located near the tip of the third elastic body 23 (hand 24), while in the contracted state shown in FIG. 3, the first and second elastic bodies 21,
The vicinity of the tip of the third extensible body 23 that accommodates 22 is located at the above-mentioned portion X. still,
In addition to the three stages shown in the illustrated example, such a telescoping telescopic body can be constructed into any number of stages as appropriate.

The portion X for distinguishing the above-described upper center rod 11 and lower center rod 12 is determined in consideration of the folding form of the folding umbrella as shown in FIG.

That is, the first determination criterion is that X is the part of the middle rod 10 that is positioned corresponding to the lower end of the lower potter's wheel 14 when the umbrella is closed. In this case, when the umbrella is closed, the lower middle rod 12 is telescopically contracted below the lower potter's wheel 14.

Further, the second determination criterion is that X is the part of the center rod 10 that is positioned corresponding to the pivot portion 25 between the main rib 19 and the small rib 20 when the umbrella is closed. in this case,
When the umbrella is closed, the lower center rod 12 is contracted in a telescopic manner near the pivot portion 25.

The illustrated embodiment simultaneously satisfies both the first determination criterion and the second determination criterion, and allows the umbrella to be folded in the most compact manner.

[Effect of idea]

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

The lower wheel 14 is driven by the upper center rod 11, and the outer diameter of the upper center rod 11 is configured to approximately match the inner diameter of the shaft hole 15 of the lower wheel 14, so that when the umbrella is closed and when the umbrella is opened. At any time, the lower wheel 14 is stably held on the upper part 11 of the center rod, and the lower wheel does not tilt or move as in the conventional case.

In this way, while the upper part 11 of the middle rod is adapted to the lower potter's wheel 14, it is possible to fold the umbrella compactly as a folding western umbrella. In other words, the lower potter's wheel 1 when closing the umbrella
4 and below the pivoting portion 25 of the main rib and coronal bone when the umbrella is closed, the middle rod lower part 12 can be retracted, so that the main rib 19 and the small rib 2 are half-folded and reversed.
Contracted body 21, 2 contracted to a length of 0
It is possible to obtain a minimum folded state with a length of 2.23, and the compactness after folding is comparable to that of conventional folding western umbrellas. Moreover,
Since the telescoping telescopic body can be constructed using the handle 24, it is possible to ensure compactness when folded and to maintain an aesthetic appearance.

In particular, according to the present invention, the telescoping body 2
1, 22, and 23 are extended, and the tip of the cotoid bone 20 is located near the handle 24 when the umbrella is closed, so it can accommodate a long distance from the handle 24 to the upper potter's wheel 13. It is possible to construct a long umbrella rib, and it is possible to construct an umbrella that spreads over a wide area even though it is a folding Western umbrella.

Furthermore, according to the present invention, the telescoping body 2 is opened and closed in a state where the lower potter's wheel 14 can be slid.
1, 22, and 23 can be expanded and contracted, so for example, when it is windy and rainy, the telescopic extensible bodies 21, 2
By contracting 2 and 23, the hand 24 is moved closer to the lower potter's wheel 14 (a position near the lower potter's wheel 14 when the umbrella is closed), and the hand 24 can be gripped in the upwardly moved position, so that strong winds can be avoided. This has the excellent effect of strongly supporting the umbrella against the elements.
