Abstract

PROBLEM TO BE SOLVED: To provide an umbrella which does not bother other people in the vehicle of a train, a bus or the like by folding the umbrella after a usage in such a manner that the surface being wet with rain of the umbrella fabric may become inside. SOLUTION: One-end sides of a plurality of subsidiary ribs 15 are axially supported by a fixed ring 13 (point D), and one-end sides of a plurality of main ribs 16 are axially supported by a movable ring 14 (point E). The other ends of the subsidiary ribs 15 are axially supported by the vicinity of the center in the longitudinal direction of the main ribs 16 (point F). A distance DF is made larger than a distance EF. By pushing up the movable ring 14 and placing the movable ring 14 under an inverted state, this umbrella 10 is placed under an open state. Thus, the surface of the umbrella fabric 17, which is the upper surface under an opened state, becomes inside under a folded state, and even when the umbrella fabric is wet right after a usage, the outside is not wet. Running raindrops concentrically run to the ferrule at the tip end of the umbrella.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an umbrella that does not bother people when a rain umbrella is brought into a train or bus.

[0002]

2. Description of the Related Art It is difficult to handle wet umbrellas when riding a train or bus on a rainy day. In particular, on crowded trains and buses when commuting, umbrellas that are wet by others are pressed against the pants, making them feel uncomfortable, or conversely, being careful not to touch others. At department stores and superstores, disposable plastic bags for umbrellas are placed at the entrance so that customers can use them to prevent the inside of the store from getting wet. Although it is good to prepare it by train, bus, etc., there is no room to prepare such a thing because there are many users. Personally, it is conceivable to carry disposable plastic bags for umbrellas and use them when needed, but I have never seen such a person because it is troublesome to prepare on a daily basis. At best, it's a platform that waits for a train, shaking an umbrella by hand and draining it.

[0003]

A conventional umbrella has a structure in which, when folded after use as shown in FIG. Thus, the present inventors have conducted intensive studies on means for solving the above problems, and as a result,
The inventor of the present invention has focused on the fact that, when the umbrella is folded, if the upper surface of the umbrella cloth, which is wet with rain, is on the inside, it does not bother others even when riding a crowded train, bus, or the like, leading to the present invention.

A conventional umbrella 1 has a structure as shown in FIG. 1 without exception. That is, a fixed ring 3 fixed near the tip of the main spindle 2 having a handle 8 fixed to one end of the main spindle 2,
The movable ring 4 is provided so as to be slidable along. One ends of the plurality of main bones 5 are pivotally supported at point A of the fixed ring 3,
One end of the accessory bone 6 is pivotally supported by the movable ring 4 at a point B. The other end of the accessory bone 6 is pivotally supported at a point C in the middle of the main bone 5. An umbrella cloth 7 is stretched over a plurality of main bones 5. Folded state (Fig. 1
When the movable ring 4 is slid upward from a) and the accessory bone 6 is pushed up, the main bone 5 is pushed up through the point C. As a result, the main bone 5 spreads laterally around the point A pivotally supported by the fixed ring 3, the umbrella cloth 7 stretched over the plurality of main bones 5, 5 is spread (FIG. 1b), and the movable ring 4 Is fixed by the stopper 9 and is in use. The umbrella cloth stretched between the main bones 5 and 5 is narrower than the state where the main bones 5 and 5 are completely opened, so that the main bones 5 and 5 do not open completely and curve inward. It has become.

In the conventional umbrella, the distance AC from the pivotally supported point A of the main bone 5 pivotally supported by the fixed ring 3 to the pivotally supported point C of the accessory bone 6, and both ends of the accessory bone 6 are axially supported. In general, AC> BC at the distance BC between the supported points C and B. The main reason is that, when AC <BC, there is a possibility that the wind is inverted as shown in FIG. 1 (c) due to a strong wind during use or the like, and the inverted state (so-called “chocolate” state) occurs. is there. Means for preventing various inversion states may be employed in addition to AC> BC, but the present invention positively utilizes this inversion state.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an umbrella in which the structure of the umbrella is reviewed and the wet surface of the umbrella cloth is inside when the umbrella is folded. With the goal. The umbrella of the present invention, in order to achieve the above object, a main shaft with a handle at one end, a fixed ring fixed to the other end side of the main shaft, one end of a plurality of sub-bones is supported, and the main shaft The movable ring is slidably mounted along one end, and includes a movable ring on which one ends of a plurality of main bones are pivotally supported, and an umbrella cloth stretched over the main bones. The other end of the accessory bone is supported at a pivot point near the center of the main bone in the longitudinal direction, and the distance from the pivot point of the main bone to the movable ring increases the distance from the pivot point of the accessory bone to the fixed ring. It is characterized by a long distance to As a material of the umbrella cloth, a water-repellent cloth having a certain degree of elasticity, a vinyl sheet, or the like is used. An umbrella cloth may be put on the accessory bone.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An umbrella 10 according to the present invention is shown in FIG.
It is configured as follows. That is, the movable ring 14 is slidably mounted in the main shaft direction R on the main shaft 11 to which the handle 12 is attached at one end, and the fixed ring 13 is fixed near the tip of the main shaft 11. One ends of the plurality of sub-bones 15 are pivotally supported on the fixed ring 13 at point D, and one ends of the plurality of main bones 16 are pivotally supported on the movable ring 14 at point E. The other end of the accessory bone 15 is pivotally supported at a point F near the center of the main bone 16. At this time, in order to easily obtain the inverted state, the distance DF is greater than the distance EF. A stone foot 20 is attached to the end of the fixed ring 13 like the conventional umbrella as an integral part of or separate from the fixed ring 13. The number of the main bones 16 and the accessory bones 15 is appropriately set to be about eight radially around the main shaft 11 as in the conventional case.

As with the conventional umbrella, the umbrella cloth 1 extends over the main bone 16.
7 is fixed to the main bone 16. The umbrella cloth 17 is preferably made of a material having a certain degree of elasticity so that the umbrella cloth 17 is easily turned over. Also, sufficient water repellency and water impermeability are required so that the outside is not wet even when the umbrella is folded while wet. The umbrella cloth 17 is generally stretched under the main bone 16 (in a state where the umbrella is spread and inserted). In this case, since the umbrella cloth 17 pulls the main bone 16 from below, the umbrella cloth 17 needs to be firmly fixed to the main bone 16 as compared with a normal umbrella. If it is devised to prevent rainwater from entering the portion where the accessory bone 15 passes through the umbrella cloth 17, it can be stretched along the opposite side (the upper side with the umbrella spread and inserted).

This umbrella is stored and carried in the state shown in FIG. In use, the handle 12 is held with one hand and the movable ring 14 is pushed up in the R direction along the main shaft 11 with the other hand, so that the main bone 16 and the accessory bone 15 gradually open. Main bone 1
The umbrella cloth 17 stretched over the umbrella cloth 6, 16 is slightly narrower than the gap between the main bones 16, 16 in a state where the main bones 16, 16 are completely opened similarly to the conventional umbrella. When tensioned, resistance is generated in pushing up the movable ring 14, but if the movable ring 14 is further pushed up against the resistance,
The umbrella 10 is inverted (FIG. 2c).

As already mentioned, the umbrella 1 according to the present invention
Numeral 0 is used in the inverted state. In the state shown in FIG. 2C, the handle 12 is held by hand and surpasses rain.
In order to prevent rainwater from leaking from between the movable ring 14 and the main shaft 11, for example, a stopper 19 made of resin or the like is provided.
The movable ring 14 is pressed against 9 and sealed. In the state shown in FIG. 2C, an upward force is applied to the movable ring 14 as a result of the entire umbrella contracting due to the contraction force of the umbrella cloth in the inverted state. However, a stopper may be provided directly below the movable ring 14 as needed. FIG. 3 shows a state in which the umbrella is folded while being wet after use. In the conventional umbrella 1 (FIG. 3a), the wet surface of the umbrella cloth is on the outside, so that the rain drops are easily scattered around. In the umbrella 10 (FIG. 3b) according to the present invention, the wet surface of the umbrella cloth is used. Is on the inside, and it can be seen that the rain drops hang down exclusively from the lower end of the umbrella.

In the umbrella according to the present invention, as shown in the perspective view (FIG. 4) showing the opened state, the main bone 16 and the accessory bone 15 and the like are removed.
Generally, the metal skeleton portion is located above the umbrella cloth 17 and is directly wetted by rainwater, which may cause rust. However, there is no problem in view of current plating technology and material technology.
On the other hand, with the umbrella according to the present invention in the open state,
Although the skeletal portion becomes completely visible from above, this is not a problem at all in terms of the function of the umbrella, and can be said to be a characteristic in appearance of the umbrella according to the present invention. In terms of design, a coloring material may be used for the metal of the skeleton. When the umbrella cloth 18 is added so as to cover the accessory bone 15 as shown in FIG. 5, the umbrella cloth 18 is placed on the upper side at least in the range of the accessory bone portion. It goes without saying that the umbrella of the present invention may be used as a parasol.

[0012]

As described above, the umbrella of the present invention has a structure completely opposite to that of the conventional umbrella as described above, and is in an inverted state when used. . In other words, when folded after use, the wet surface of the umbrella cloth is on the inside, so that even on crowded trains and buses, there is no trouble to the surroundings due to rain drops. The rain drops only hang from the tip of the umbrella near the foot.
