Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable umbrella, and more particularly to a foldable umbrella, which is easy to open and close and handles the foldable umbrella. It relates to an excellent folding umbrella.

[0002]

2. Description of the Related Art An umbrella or a parasol can be opened or closed by attaching a plurality of bones radially to a handle provided with a handle at the lower end thereof and moving the portion where these bones are gathered around the handle up and down. That is the general configuration. The pattern is classified into two types: a long one with a covering cloth that expands spherically when opened, and a folding type that closes by double- or triple-wrapping the covering cloth with the handle being telescopic. Is done.

FIG. 9 is a schematic diagram showing the opening and closing of a covering cloth in the case of a single long real handle. As shown in FIG.
The covering cloth 21 hanging around like an elongated triangular hood is moved upward by moving an annular ring 23 provided at the base end of a large number of bones 22 connected to supporting bones arranged on the covering cloth 21. Then, as shown in FIG. When the ring 23 is hooked on a hook provided on the upper end side of the handle 20, the ring 23 is restrained, and the bone 22 is stretched as shown in FIG. expand.

[0004] The opening and closing of the covering cloth 21 is basically the same for a folding umbrella, and for both long and folding umbrellas, as described above, the handle portion of the handle is used. The cover cloth is expanded by pulling the gathered portion of the bone upward from the above, and the cover cloth 21 is folded down by pulling it back to the handle side.

However, when getting off a car or a bus, the covering cloth 21 is caught on the door with the covering cloth 21 opened, so that the covering cloth 21 is opened after leaving it closed or slightly opened. For this reason, since the umbrella is opened while being exposed to the rain, the clothes and the like are wetted with the rain until the umbrella is opened. Then, even when getting into the car from the rain, it is necessary to close the cover cloth 21 and then get on the vehicle, so that the head and clothes are similarly wet before getting on the vehicle.

When the covering cloth 21 is closed, the surface of the covering cloth 21 which has been wet by the rain remains facing the front side, so that it can be carried around as it is or after getting on a car or a bus.
Water droplets adhering to the surface of the covering cloth 21 on clothes, seats, and the like drip or touch and wet them.

[0007] Such a disadvantage is that even with a folding umbrella, when the covering cloth is opened, the covering cloth folded in an elongated triangular width spreads as it is, and when the covering cloth is closed, the opposite movement is performed. Occur.

[0008] In response to the above problems, the present applicant has
We have already proposed a folding umbrella in which the bone and the covering cloth change their posture so that the surface of the covering cloth does not become exposed to the outside when the umbrella is folded.
No. 057.

In this folding umbrella, when the folding umbrella is folded, the top of the umbrella is made into a mountain and the surrounding covering cloth is deformed into a substantially W-shape, so that the surfaces of the covering cloth overlap with each other and the covering cloth overlaps. Can be folded so that the back side faces outward. By adopting such a folding system, it is possible to fold the surface of the covering cloth wet with the raindrops without facing the front side, and it does not wet the clothes and the like of the surrounding people even when getting on a bus or the like. .

[0010]

However, in the folding umbrella according to the earlier application, although the function of preventing wetting can be sufficiently performed, the bone wrapping around the inner surface side of the covering cloth is exposed to the outside when folded. Therefore, there is an unfavorable surface in terms of appearance. In particular, in the case where emphasis is placed on fashionability, such bare bones are a major obstacle to commercialization.

On the other hand, most of the conventionally used double fold or triple fold umbrellas have a combination of an umbrella body and a cover for covering the umbrella when folded. In such a folding umbrella, when folding the umbrella body, the covering cloth is folded together with the bone, so this covering cloth is folded so that the folds are aligned, but this handling is quite troublesome and messyly folded. It may not be possible to cover it. Then, since the covering cloth with the raindrops is folded, the clothes as well as the hands may be wetted by the raindrops, and the usability is not always good.

Further, the cover paired with the umbrella body is made of cloth of the same material as the covering cloth. For this reason,
The cover is very convenient to carry because it can be rolled up small, but when the umbrella body wet with raindrops is covered, the raindrops infiltrate into the cover and the cover becomes water-containing. Therefore, it does not cause the user's clothes to get wet, but it is inconvenient to store the umbrella in a bag or handbag as it is. For this reason, the umbrella itself needs to be handled differently from other portable items,
There is also a usability problem in this respect.

As described above, in the conventional folding umbrella, there is a problem that it is troublesome to fold the covering cloth, and if the cover is put on with the raindrops attached, the raindrops permeate the cover and it is difficult to handle. In the case of the above-mentioned application, it is possible to prevent clothes and vehicle seats from being wet by raindrops when the umbrella is folded, but there is a need for improvement in fashionability.

An object of the present invention is to provide a folding umbrella which is easy to handle at the time of folding and which can prevent external wetting due to raindrops even if there are attached raindrops.

[0015]

It is a lightweight one that is moderate. The grip 2 and the cap 3 are bowl-shaped with one end in the axial direction closed using a pipe material having the same outer diameter as that of the case 1. It is preferable to use different colors or patterns. Further, the grip 2 may be formed in an irregular shape on the surface so as to be easily grasped by a hand, or may be formed in a U-shaped shape like an umbrella shown in the conventional example, instead of the cylindrical shape shown in the figure.

The cap 3 is connected to the case 1 by a chain member 3a such as a string or a chain. As shown in an enlarged view in FIG. The step 3b is formed on the upper end of the case 1 in a watertight manner. In order to increase the watertightness, a packing may be provided between the outer peripheral surface of the step portion 3b and the inner peripheral surface of the case 1, and a screw may be cut in place of the case having the step portion 3b. 1 may be screwed on and removed.

With such a combination of the case 1, the grip 2 and the cap 3, the umbrella has a total length of 60.
It can be grouped into an elongated rod shape of about 0 mm, and the whole has an appearance covered with three members made of a synthetic resin material.

FIG. 3 is a schematic longitudinal sectional view when the umbrella is opened.

The proximal end of the telescopic rod 4 is connected to the grip 2 and coaxially inserted into the case 1. The telescopic rod 4 is formed by connecting two rods 4a and 4b by a telescopic mechanism, and a lock block 4c is fixed to a tip of the upper rod 4a. Rods 4a, 4
The length of b is slightly shorter than the length of the axis of the case 1, and when these rods 4a and 4b are contracted,
When the telescopic rod 4 is accommodated in the case 1 and is extended to the maximum length, about half of the axial length of the upper rod 4a protrudes from the upper end of the case 1 as shown in FIG.

A base retainer 5 and a top retainer 6 for supporting an umbrella frame are provided inside the case 1.
Are provided so as to be movable in the axial direction.

The base retainer 5 is an annular body movably extrapolated around the extensible rod 4, and turns the base ends of a plurality of support members 7 constituting a part of the umbrella frame vertically in FIG. It is linked movably. The top retainer 6 is also an annular body externally movably mounted around the telescopic rod 4 and has a smaller outer diameter than the base retainer 5. A plurality of ridge aggregates 8 of an umbrella framing frame are similarly connected to the top retainer 6 so as to be rotatable vertically in FIG.

The supporting aggregate 7 and the ridge aggregate 8 have the same length relationship as that shown in the conventional example, and the distal end portion of the supporting aggregate 7 and a substantially intermediate portion in the longitudinal direction of the ridge aggregate 8 are provided. Are connected to each other so as to be bendable by a joint 9 using a hinge mechanism. Then, the covering cloth 10 which has been subjected to a water-repellent treatment or the like is covered on the entire surface of the ridge aggregate 8. This covering cloth 10 may be cloth cloth or a synthetic resin sheet of vinyl or the like, similarly to a conventional umbrella.

FIGS. 4 and 5 are longitudinal sectional views of main parts showing details of the upper end and lower end of the telescopic rod 4 when the supporting aggregate 7 and the ridge aggregate 8 are folded and stored in the case 1. .

As shown in FIG. 5, the outer diameter of the annular base retainer 5 is slightly smaller than the inner diameter of the case 1,
The outer peripheral surface and the inner peripheral surface are provided with packings 5a and 5b such as O-rings for sealing. These packings 5a, 5b
The thickness of the bulge in the radial direction is such that the sliding resistance received from the inner periphery of the case 1 when the base retainer 5 moves does not increase. Further, the top retainer 6 is provided with a lock groove 6a for connection to and release from the telescopic rod 4, and the lock block 4c is provided with a key 4d engaging with the lock groove 6a as shown in FIG. . A stopper 1a for restricting the movement of the base retainer 5 when the umbrella is opened is provided on the inner periphery on the upper end side of the case 1.

FIG. 6 is a perspective view showing a main part of the top retainer 6 and the lock block 4c. Lock grooves 6a are formed at two locations facing the top retainer 6 in the radial direction, and the lower part is formed from the upper surface of the top retainer 6. And has a substantially L-shaped opening shape with an engagement groove 6b whose lower end is bent in the circumferential direction. On the other hand, the key 4d of the lock block 4c is
The lower end thereof has a circumferential length that can be inserted from the upper end of the lock groove 6a, and an engaging element 4e that enters the engaging groove 6b when the top retainer 6 is turned clockwise in a plan view when viewed from above the upper retainer 6 is formed. doing.

With such a configuration of the lock block 4c and the top retainer 6, after the telescopic rod 4 is pulled down and the key 4d is inserted into the lock groove 6a, the telescopic rod 4
Is rotated about its axis to engage the engaging element 4e with the engaging groove 6b.
You can get inside. Thus, the telescopic rod 4 and the top retainer 6 can be connected and restricted in the axial direction, and the connection is released by rotating the telescopic rod 4 in the opposite direction.

FIG. 7 is a longitudinal sectional view showing the internal state when the umbrella is folded as shown in FIG. 1, in which the rods 4a and 4b are contracted, and the lock block 4c is positioned at its tip as a free end. The base end of the support aggregate 7 is held by the base retainer 5, and the base end of the ridge aggregate 8 is held by the top retainer 6, and an intermediate portion thereof is connected to the support aggregate 7 by the joint 9, and the case 1 is folded and stored together with the covering cloth 10.

In the above configuration, in order to open the umbrella of FIG.
, And the grip 2 is pulled out from the lower end of the case 1 as shown in FIG. Thus, the telescopic rod 4 connected to the grip 2 is extended by its own telescopic mechanism so that the two rods 4a and 4b are extended from each other. If the lock block 4c is brought into contact with the top retainer 6 when the rods 4a and 4b reach the maximum length, the key 4d can be inserted into the lock groove 6a. Thereafter, as described above, when the grip 2 is turned about 90 ° in the direction of the arrow in FIG. 8, the engaging element 4e at the lower end of the key 4d enters the engaging groove 6b of the top retainer 6. In addition,
As shown in FIG. 5, the upper surface of the top retainer 6 and the lower surface of the lock block 4c, which are in contact with each other, are provided with packings 4f to prevent leakage of rainwater from the apex when the umbrella is opened. . Also, a packing (not shown) such as an O-ring is incorporated into the inner peripheral surface of the top retainer 6, and similarly, when the umbrella is opened, rainwater is transmitted from the telescopic rod 4 and does not wet the grip 2 side. Is preferred.

After the engagement between the lock block 4 c and the top retainer 6, the user holds the case 1 by hand and pushes the grip 2 toward the case 1 so that the top retainer 6 is also integrated with the telescopic rod 4. It moves and the ridge aggregate 8 is fed out from the upper end of the case 1 in order from the tip side. During the feeding period of the ridge aggregate 8, the covering cloth 10 integrally attached to the ridge aggregate 8 is also fed out of the case 1 in a state of being folded. The lock block 4c
The lock mechanism between the upper retainer 6 and the top retainer 6 is formed by forming a lock block 4c into a cone shape having a tapered lower end side instead of the one shown in FIG. A mechanism that can be engaged and released by rotation or the like may be used.

When the ridge aggregate 8 moves, the base retainer 5 connected to the ridge aggregate 8 via the supporting aggregate 7 also moves in the feeding direction, whereby the ridge aggregate 8 and the supporting aggregate 7 move integrally. . During the period in which the top retainer 6 is located below the joint 9, the support aggregate 7 and the ridge aggregate 8
Moves while maintaining the posture as shown in FIG.
The telescopic rod 4 further rises even after having escaped from the upper end of the case 1. When the telescopic rod 4 rises and passes the joint 9 from below to above, the connecting point between the ridge aggregate 8 and the top retainer 7 and the upside down position of the joint 9 are in the posture shown in FIG. Crest aggregate 8 and support aggregate 7
The posture is changed as shown in FIG.

The telescopic rod 4 rises until the base retainer 5 abuts against the stopper 1a. At this time, the upper end of the rod 4a in the upper stage protrudes above the case 1. During this movement, the ridge aggregate 8 and the supporting aggregate 7 change their postures as shown in FIG. 1, and finally open the ridge aggregate 8 as shown in FIG. The umbrella can be opened by deploying the covering cloth 10.

When closing the umbrella, the grip 2 is lowered with respect to the case 1 in FIG. Thereby, the top retainer 6 pushes down the upper end of the ridge aggregate 7 corresponding to the apex of the opened umbrella, the ridge aggregate 7 changes its posture in the direction of the arrow in FIG. 1, and the covering cloth 10 is folded inward. To go. Therefore, when the covering cloth 10 is opened, the surface to which rain adheres is wrapped inside, and even when the umbrella is not stored in the case 1 before the umbrella is completely closed, the umbrella touches the clothes. It does not wet with the attached drops.

When the grip 2 is further lowered, the supporting aggregate 7 and the ridge aggregate 8 are stored in the case 1 while maintaining the mutual posture shown in FIG. At this time, the covering cloth 10
Is folded at the same time as the ridge aggregate 8 is folded, so that there is no need to handle the covering cloth 10 by touching it.
After this storage, the grip 2 is rotated in the direction opposite to the first rotation direction, and the engaging element 4e is detached from the engaging groove 6b, so that there is a degree of freedom in the axial direction. This allows
As shown in FIG. 7, the rods 4a and 4b are contracted so that the telescopic rod 4 can be housed in the case 1, and the grip 2
When the cap 3 is put on both ends of the case 1 and closed, the appearance shown in FIG. 1 can be obtained.

When the umbrella is folded in this way, the covering cloth 1
0, even if raindrops adhere to the surface of
The case 1 enclosing the portion is sealed at its lower end by the packings 5a and 5b of the base retainer 5, and is closed at the upper end by the cap 3 in a watertight manner, so that it is thin but does not leak out. Therefore, when the umbrella is folded, the covering cloth 10, the support aggregate 7, and the ridge aggregate 8
Since none of them are exposed, they can be compactly collected and stored in a bag or the like as they are.

[0039]

According to the first aspect of the present invention, the umbrella can be opened or closed simply by moving the telescopic rod with respect to the case, so that there is no need to fold the covering cloth as in the conventional case, and the handling is simplified. In addition, when the cover is closed, the surface of the covering cloth is folded inward, so that the clothes and the like do not get wet when getting on or off a car or a bus, and the usability is greatly improved as compared with a conventional folding umbrella. Further, when folded, the appearance becomes a case, a grip and a cap, and a compact and fashionable product can be provided.

According to the second aspect of the present invention, if the supporting aggregate, the crest aggregate and the covering cloth are folded in the case after use, the sealing is achieved by the sealing material of the cap and the base retainer.
Adhered rainwater does not leak out of the case, and can be stored and carried in a bag or the like as it is, and the usability is further improved.
