Description

[Detailed description of the invention] (Technical field of invention) This invention relates to an umbrella.

(Background of the Invention) All umbrellas are designed to be folded so that the outer periphery of the umbrella is converged toward the handle. However, this folding format is often inconvenient. For example, when I get into a small car interior on a rainy day, I move my body inside the car and then close the umbrella, but when folding the umbrella, I put my hand inside the umbrella and move it towards me. Since the umbrella is retracted, the tip of the umbrella hits the door, etc., making the folding operation extremely complicated.

Also, when folding the folding bag, the wet side is on the outside, which can cause your hands to get wet or your clothes to get wet. Another inconvenient example is that when the umbrella is taken out from the umbrella stand, the tip of the clogged umbrella opens, making it difficult to take it out.

(Purpose of the Invention) The present invention aims at folding an umbrella so that the rain-wet cloth surface is on the inside, and the folded end is positioned at the end of the shaft. The purpose is to resolve the inconveniences of

(Structure and Effect of the Invention) In order to achieve the above object, the present invention provides a shaft having a handle at one end, an auxiliary bone support member fixed to the other end of the shaft, and a shaft movable along the shaft. a main bone support member, one end of which is rotatably supported by the main bone support member; one end of which is rotatably supported by the main bone support member; It consists of an auxiliary bone that supports the main bone, an elastic body that restricts the approach position of the main bone support member to the auxiliary bone support member, and an umbrella cloth whose outer end is fixed to the tip of the main bone, and which supports the main bone support member. Move the auxiliary bone to the main bone
When the support point of the main bone crosses the plane connecting the support point for the main bone support member and the tip of the main bone, it is reversed due to the spring properties of the main bone, and when the umbrella opens, the tip of the main bone faces the handle side. When the umbrella is closed, the tip of the main bone faces toward the auxiliary bone support member and closes.

According to the above configuration, since the umbrella cloth closes from the front side to the tip side, even if it is taken into a narrow gap such as a car door, raindrops will not fall on the hand, and moreover, the umbrella cloth will close from the front side to the tip side. It can be taken in without getting caught.

In addition, this invention also allows you to fold a used umbrella so that the side exposed to the rain is on the inside when you take it onto a crowded train, for example.
No raindrops remain on the outside. Therefore, this invention can eliminate the problem of getting clothes wet due to contact with not only the user but also other people.

In addition, in the folded state, when the handle is on the upper side, the tips of the main ribs that support the umbrella cloth are open and stand on their own.
No umbrella stand required. Even if it is inserted into an umbrella stand, it will not get caught in the direction of removal, making it easy to take out.

(Example) FIG. 1 is a perspective view showing a first embodiment of the invention.

In the figure, 1 is a shaft with a handle 2 provided at one end. An auxiliary bone support member 3 is fixed to the other end of the shaft 1, and a kill tube 4 is further fixed to the tip thereof.

A main bone support member 5 is slidably disposed on the shaft 1 between the handle 2 and the auxiliary bone support member 3. The main bone support member 5 is locked by click stoppers 6.7 installed at the upper and lower ends of the shaft 1, and is unlocked by manual operation. One ends of a plurality of main bones 8 are rotatably supported on the outer peripheral portion of the main bone support member 5 and are arranged radially around the main bone support member 5 .

Further, one end of an auxiliary bone 9 is rotatably supported on the peripheral edge of the auxiliary bone support member 3. The other end of the auxiliary bone 9 is the main bone 8
The main bones 8 are rotatably connected to the middle part of the main bones 8, and support each main bone 8. Furthermore, a compression coil spring 1o is interposed in the lower part of the auxiliary bone support member 3 to maintain a predetermined distance from the main bone support member 5.

In the umbrella with the above framework, the center part of the umbrella cloth 11 shown by the imaginary line C in the figure is fixed to the lower part of the flange surface of the main frame support member 5, and the outer end part is fixed to the lower tip of the main frame 8. . A thread or the like is used as the fixing means.

As a result, when the umbrella is opened as shown in FIG. 1, the main bone 8 and the auxiliary bone 9 are exposed to the outside.

When the umbrella is folded as described above, the main bone support member 5 is in the closest position to the handle 2, as shown in FIG. be.

Next, when opening the umbrella, the main bone support member 5 is attached to the shaft 1.
When you slide it toward the tip along the
As shown in B), due to the displacement of the support point of the auxiliary bone 9 relative to the main bone 8 as it moves, the main bone 8 curves into an S-shape with the support point of the auxiliary bone 9 relative to the main bone 8 as a base point. When the main bone support member 5 is further raised from this state, the support point crosses the reversal line L of the plane connecting the support point of the main bone 8 with respect to the main bone support member 5 and the tip of the main bone 8, and Due to the spring properties and the tensile action of the umbrella cloth 11, the main ribs 8 are inverted with respect to the main bone support member 5, and the tips of the main ribs 8 open toward the handle 2 side.

The state shown in FIG. 2(C) is immediately before that, in which the compression coil spring 10 interposed between the auxiliary bone support member 3 and the main bone support member 5 is compressed. When the reversing operation is completed, the spring action of the spring 10 causes the state shown in Fig. 2 (D
), the main bone support member 5 is pushed back to the lower side and fixed in the umbrella open state by the click stopper 6 provided on the -F end side. That is, when the spring 10 is compressed and the main bone support member 5 crosses the reversal line l and allows the main bone 8 to be reversed, the main bone 8 is parallel to the auxiliary bone 9 after the reversal, It has the function of a spacer to prevent the situation that occurs with ordinary umbrellas.

To close the umbrella, the click stopper 6 is pressed to release the engagement, and the spring pressure of the spring 10 causes the main bone support member 5 to descend somewhat. When the spring pressure of the spring 10 is no longer applied, if you pull the main bone support member 5 toward you, as shown in Fig. 2(A).
~ (D) can be filled in the reverse order.

In this embodiment, there is a risk that rain may leak from the gap between the main bone support member 5 and the shaft 1, but this can be prevented by arranging a sealing member.

FIG. 3 shows a second embodiment of the invention. Note that the same parts as in the first embodiment are given the same reference numerals, and only the main parts will be explained. In the figure, a spacer 20 made of an elastic member is fitted and fixed to the lower end of the auxiliary bone support member 3, and a spacer 21 made of the same material is fitted and fixed to the outer periphery of the upper end of the main bone support member 5.

Each spacer 20, 21 has the same function as the spring 10 in the previous embodiment, and in addition, both spacers 20 and 21 have the same function as the spring 10 in the previous embodiment.
0.21 has the function of sealing the gap between the shaft 1 and the main bone support member 5 by the elastic contact between the end surfaces.

In FIG. 3, reference numeral 1a is a bolt provided at the tip of the shaft 1, and 4a is a seal ring.The bolt 1a is inserted into the auxiliary bone support member 3, and the cap 4 is screwed onto the protruding end of the bolt 1a through the seal ring. By inserting the auxiliary bone support member 3 into the shaft 1, the auxiliary bone support member 3 is fixed to the distal end of the shaft 1.

In this embodiment, the spacer is provided facing each support member 3.5, but the same function can be achieved even if the spacer is provided on either one of the support members 3.5.
