Description

[Detailed explanation of the invention] Purpose of the invention (industrial application field) This invention relates to an umbrella, and more specifically, when the umbrella is folded, the rain-wet cloth is folded so that the surface of the cloth is inside, and the clothes are folded. The invention relates to a foldable umbrella that does not get wet objects, etc.

(Conventional technology) Conventional folding umbrellas have a retractable handle and
A plurality of first support bones are attached to the upper part of the same handle so that they can be opened and closed and are attached radially; and a second support bone that can be opened and closed from the first support bones and is biased into an open state by a spring. When the handle is shortened, the bias of the second support bone by the spring is released, and the second support bone is folded by turning it over by hand.

(Problem that the invention aims to solve) However, when the above-mentioned conventional folding umbrella is folded up and not in use, the surface of the cloth wet with rain remains on the outside, so when riding a bus or train, etc. , there is a problem that clothes etc. get wet.

Also, when riding in a passenger car, you cannot put an umbrella in the car unless it is folded, and when you get out of the car, you cannot open the umbrella unless you take the whole umbrella out the door, and during that time, you cannot open the umbrella. There is a problem that the parts etc. get wet. Furthermore, if you place an umbrella at the foot of the passenger seat or rear seat in the car,
There is also the problem that raindrops dripping from the umbrella can wet clothes, the inside of the car, etc.

Structure of the invention (means for solving the problem) In order to solve the above-mentioned problem, this invention has a plurality of first support bones 3 that can be opened and closed from the upper part of the handle 1,
In addition to being attached radially, a second support bone 7 is pivotally attached to the distal end of each first support bone 3 so that it can be opened and closed relative to the first support bone 3, and extends in the vertical direction with respect to the handle 1. Connecting bones 9 for opening and closing the first supporting bones 3 are connected between the slidably attached sliding ring 11 and the intermediate portion of each of the first supporting bones 3 so as to be relatively rotatable. In a folding type umbrella in which a rain-catching cloth is attached to the first support bone 3 and each second support bone 7, a lever portion 7a is provided protrudingly on the side where the shaft 8 of each second support bone 7 is attached, A first connecting rod 13 for opening the second support bone 7 is articulated between the intermediate portion of each connecting bone 9 and each lever portion 7a so as to be relatively rotatable.
A second support bone 7 is provided between the support bone 3 and the second support bone 7.
A second connecting rod 16 for closing the door is connected so as to be relatively rotatable.

(Function) When the sliding ring is moved upward along the handle of the umbrella, the connecting bone is moved upward and the first supporting bone is moved in the opening direction, and the displacement of the connecting bone causes the first connecting rod to move upward. The second support bone is opened in the direction away from the first support bone.

Furthermore, when the sliding ring is moved down along the handle of the umbrella, the connecting bone is moved down and the first supporting bone is moved in the closing direction, and as the first supporting bone is moved downward, the first supporting bone is moved downward. The second support bone is folded toward the first support bone by the two consecutive rods, and the rain-wet surface of the cloth becomes inside.

(Example) An example embodying this invention will be described below with reference to the drawings, but the description of the umbrella cloth that catches the rain will be omitted.

A fixed support ring 2 is fixed to the upper end of the extensible handle 1, and a plurality of first support bones 3 are attached to the fixed support ring 2.
(only one is shown in this embodiment) is attached at the proximal end so as to be openable and closable, and radially. Same 1st
A link 4 for opening the support bone 3 is pivoted near the base end of the support bone 3, and the lower end of the link 4 is attached to a sliding ring 5 slidably fitted to the handle 1. It is attached so that it can rotate. A tension spring 6 is provided between the sliding ring 5 and the fixed support ring 2.
is interposed, and the first
The support bone 3 is always urged in the opening direction (upward in the drawing).

At the tip of the first support bone 3, a second support bone 7 is attached to a shaft 8 near its base end so as to be openable and closable.
Further, a connecting bone 9 for opening and closing the first supporting bone 3 is attached to a shaft 10 near the middle part of the first supporting bone 3 so as to be relatively rotatable, and the proximal end of the connecting bone 9 slides on the handle 1. It is rotatably attached to a sliding ring 11 that is movably fitted.

A lever portion 7a is protruded from the proximal end of the second support bone 7, and a connecting portion 12 having an oblique long hole 12a is integrally formed at the distal end of the lever portion 7a. Further, a connecting portion 15 having an oblique long hole 15a is formed in the second support bone 7 near the shaft 8.

Between the elongated hole 12a and the shaft 14 at the intermediate portion of the connecting bone 9, there is a first connecting rod 13 for opening the second supporting bone 7, which is composed of a coil spring 13a, a linear portion 13b, and a locking portion 13c. are articulated to allow relative rotation and relative movement. On the other hand, the long hole 15a and the shaft 1
0, there is a second support bone 7 consisting of a coil spring 16a, a flexible linear part 16b, and a locking part 16c.
A second connecting rod 16 for closing is articulated so as to be relatively rotatable and movable. Ryorenji 13, 16
is at its natural length when the umbrella is folded as shown in Figure 1. Note that the coil spring 16a has a smaller spring constant than the coil spring 13a.

Further, a notch recess 3 is provided at the distal end of the first support bone 3 for allowing the two connecting portions 12 and 15 to enter.
a is formed, and when the umbrella is closed (see Figure 1), the second support bone 7 is brought into close contact with the first support bone 3, and when the umbrella is opened (see Figure 3), the second support bone 7 is brought into close contact with the first support bone 3. The second supporting bone 7 is arranged in substantially a single linear shape.

The sliding ring 1 is located at two locations above and below the middle part of the handle 1.
Clasps 17 (Fig. 1), 18 for locking 1
(FIG. 3) is provided so as to be freely protrusive and retractable by a spring (not shown), and both clasps 17 and 18 are adapted to hold the umbrella in a closed state and an open state, respectively.

Next, the operation of the folding umbrella constructed as described above will be explained.

When the umbrella is folded as shown in Figure 1, the clasp 1
When the sliding ring 11 is released from the locking of the sliding ring 11 by the sliding ring 7, the first supporting frame 3 holds the fixed supporting ring 2 by the urging force of the tension spring 6 via the sliding ring 5 and the link 4, as shown in FIG. It opens at the center. Along with this, the connecting bone 9 is moved upward, and this displacement of the connecting bone 9 causes the first connecting rod 13 to move upward.
is transmitted to the lever portion 7a of the second support bone 7 via
The second support bone 7 is rotated about the shaft 8 in the direction of the arrow P, and is separated from the first support bone 3 and opened. At this time, the coil spring 13a of the first link 13 is hardly expanded, and the coil spring 16 of the second link 16 is not expanded.
a is extended and energy is stored.

After that, as shown in FIG. 3, when the sliding ring 11 is locked to the upper latch 18, the coil spring 13a of the first link 13 is expanded and stored, and the umbrella is held in the open state. and is ready for use.

When closing the umbrella, after releasing the locking of the sliding ring 11 by the clasp 18 in the open state shown in FIG. and lower it. At this time, since the stored force of the coil spring 13a of the first link 13 and the biasing force of the tension spring 6 almost cancel each other out, the sliding ring 11 can be easily moved downward. As shown in FIG. 2, as the sliding ring 11 moves downward, the second support bone 7 rotates in the direction of the arrow Q around the shaft 8 due to the stored force of the coil spring 16a of the second link 16. The cloth is moved closer to the first support bone 3, and the rain-wet surface of the cloth is folded inward. Thereafter, when the sliding ring 11 is engaged with the catch 17, it is held in the contracted state as shown in FIG.

Now, in this embodiment, a lever part 7a is provided protrudingly on the side where the shaft 8 of each second supporting bone 7 attaches, and a second lever part 7a is provided between the intermediate part of each connecting bone 9 and each lever part 7a.
A first connecting rod 13 for opening the supporting bone 7 is articulated so as to be relatively rotatable, and the first supporting bone 3 and the second supporting bone 7
Since a second connecting rod 16 for closing the second support bone 7 is connected to the second support bone 7 in a relatively rotatable manner, the second support bone 7 can be opened and closed easily and reliably.
When you bring a folded umbrella onto a bus, train, or car, the umbrella will be folded so that the rain-soaked surface of the umbrella is on the inside, so that the bodies, clothes, and belongings of those around you will not get wet. It is highly public interest.

Further, in this embodiment, a diagonal long hole 15a is provided in the connecting portion 15 formed in the second support bone 7, and
Since a part of the connecting rod 16 is a coil spring 16a, and the position of the locking part 16c with respect to the connecting part 15 can be moved relative to the connecting part 15, the second support bone 7 is moved to the first position when the umbrella is folded as shown in FIG. It can be brought into close contact with the supporting bone 3.

Effects of the Device As detailed above, in this device, a lever portion is provided protruding from the pivoting portion side of each second supporting bone, and a lever portion is provided between the intermediate portion of each connecting bone and each lever portion. A first connecting rod for opening two supporting bones is articulated so as to be relatively rotatable, and a second connecting rod is connected between the first supporting bone and the second supporting bone.
Since the second connecting rod for closing the supporting ribs is articulated so that it can rotate relative to each other, the umbrella can be opened and closed easily and reliably. Since it can be folded, your body, clothes, belongings, etc. will not get wet when you take this umbrella onto a bus, train, or passenger car, and it will also be very unlikely to get wet when getting on and off a passenger car, making it of high practical value. It is something.
