Abstract

PURPOSE:To provide a foldable umbrella which is greatly miniaturized so as to be carried in a pocket by providing such a configuration that a lower pulley is pushed up along a first shank while first and second stays are retracted so that the retracted stays may be stored in a U-like groove in an upper side umbrella frame which is also retracted. CONSTITUTION:When a foldable umbrella is to be stored, first and second ribs members 10 and 11 of an upper umbrella frame 9 are slightly retracted, and first and second stays 14, 15 of a stay assembly 13 are slightly retracted. Accordingly, a locking part 22b at the peripheral edge of an umbrella fabric 22 can be easily removed from the front end of a fourth rib 4, and then the center of the umbrella fabric 22 is drawn upward by a hand so as to remove the umbrella fabric 22 can be removed from the upper and lower umbrella frames 9, 18. After fourth and third ribs 21, 20 of the lower umbrella frame 18 are retracted, they are folded back upward through a hinge mechanism 19, and then, first, second, third and fourth shanks 2, 3, 4, 5 are successively pushed into so as to shorten the length of the umbrella, thereby it is possible to make the structure body section of the umbrella in an extremely compact size.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a folding umbrella.

[Prior Art] A conventional general folding umbrella has a shaft handle that can be expanded and contracted into two or three stages, an umbrella rib that can be folded into two or three stages is attached to the uppermost shaft handle, and this umbrella rib It has a structure in which cloth is attached to the top. The other end of the stay, which is connected to a potter's wheel slidably attached to the uppermost shaft handle, is connected to the umbrella rib, and the umbrella rib is expanded through this stay to spread the upholstery. Further, the stay may also have a foldable two-stage structure.

[Problems to be Solved by the Invention] It is desired that a folding umbrella can be folded as small as possible, but the most important point in making the umbrella smaller is how small the umbrella ribs and stays can be made. However, conventional folding umbrellas have a structure in which the umbrella ribs or stays can be folded, and the umbrella does not necessarily become sufficiently small when folded.

Furthermore, even if the umbrella ribs and stays are made to be extendable and retractable, there is still a limit to miniaturization if the umbrella ribs and stays are made to be extendable. It is difficult to make it as small as possible.

The present invention has been made in view of the above circumstances, and an object of the present invention is to obtain a folding umbrella that can be significantly downsized to the extent that it can be put in a pocket.

Means for Solving the Problems] In order to solve the above problems, the present invention provides a shaft handle having at least a first shaft handle and a second shaft handle connected to each other in an expandable manner, and an upper end of the first shaft handle. A second umbrella rib, which is substantially U-shaped like the first umbrella rib and whose one end is connected to an upper raceway provided at the top wheel, and which is slidably fitted in the first umbrella rib in the longitudinal direction.
a reducible insert-type upper umbrella rib consisting of an umbrella rib; a lower umbrella rib consisting of a plurality of parts that can be folded or expanded and connected to the lower end of the upper umbrella rib so as to be foldable upward; A first shaft, one end of which is vertically rotatably connected to a lower wheel that is slidable along the first shaft handle, and the other end of which is vertically rotatably connected to the lower end of the upper umbrella bone.
an expandable and retractable insert-type stay consisting of a stay and a second stay; a center portion is removably housed in the upper end of the first shaft handle; a peripheral portion is removably attached to the lower end of the lower umbrella bone; and an upholstery cloth attached to the stay, wherein the stay reduces the first umbrella rib and the second umbrella rib of the upper umbrella rib and reduces the first stay and the second stay of the stay while reducing the lower umbrella rib. The folding umbrella has such a shape and size that the reduced stay is housed in the U-shaped space of the reduced upper umbrella rib when the potter's wheel is pushed up along the first shaft handle.

[Operation] When storing the above-mentioned folding umbrella, the upholstery is removed from the upper umbrella rib and the lower umbrella rib, the first umbrella rib and the second umbrella rib of the insertable upper umbrella rib are reduced, and the same is true. When the lower wheel is pushed up along the first shaft handle while reducing the first and second stays of the insert type stay, the reduced stay is stored in the U-shaped groove of the reduced upper umbrella rib. Ru. In this way, the space in the U-shaped groove of the upper umbrella rib is effectively used, so the upper umbrella rib and stay portion in the folded state are kept small, and the structure of the folding umbrella excluding the upholstery becomes sufficiently small. . Note that the upholstery may be folded and stored separately, or wrapped around the folded structure.

Moreover, in the folding umbrella of claim 2, the folded structure portion can be stored in the case that also serves as the shaft handle. In this case, it is also possible to wrap the removed upholstery around the structure and store it in a case that also serves as a shaft handle.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 9.

FIG. 1 shows the structure of a folding umbrella according to an embodiment of the present invention, excluding the upholstery. It consists of a fourth shaft handle 5. The first shaft handle 2 can be stored in a cylindrical second shaft handle 3,
The second shaft handle 3 can be stored in the third shaft handle 4, which is also cylindrical, and the third shaft handle can be stored in the fourth shaft handle 5, which is also cylindrical.

That is, the first shaft handle 2, the second shaft handle 3, the third shaft handle, and the fourth shaft handle 5 are connected in a plug-in manner that can be expanded and contracted in sequence.

An upper wheel 6 is fixed to the upper end of the first shaft handle 2, and a lower wheel 7 is provided so as to be slidable down along the first shaft handle 2. Furthermore, a projection 8 for positioning the center of the upholstery 22 is provided at the upper end of the first shaft handle 2, as will be described later.

As shown in an enlarged cross-section in FIG. 2, the upper umbrella rib 9 is substantially U-shaped and has an inward protrusion 10a for guiding at its end edge. and a second umbrella rib 11 that is slidably fitted into the first umbrella rib 10, and the upper end of the first umbrella rib 10 is connected to the upper lathe wheel 6 via an annular wire (or an individual bottle) 12 in the upper and lower directions. It is connected so that it can rotate in the direction. Although details are omitted, the second umbrella rib 11 is fitted with the first umbrella rib 10 in a structure that allows it to be held in an extended state as shown in FIG.

As shown in an enlarged cross-section in FIG. 3, the stay 13 for supporting the upper umbrella rib 9 includes a cylindrical first stay 14 and a similarly cylindrical first stay 14 that is slidably fitted into the first stay 14. As shown in FIG. 4 and FIG. movably connected. Further, one end of the second stay 15 is connected to the lower end portion of the second umbrella rib 11 via a pin 17 so as to be rotatable in the vertical direction. Although details are omitted,
The second stay 15 has a structure that allows it to be held in an expanded state as shown in FIG. 1, and is fitted into the first stay 15.

Further, a lower umbrella rib 18 is connected to the lower end of the upper umbrella rib 9, that is, the lower end of the second umbrella rib 11 via a hinge fitl119 so as to be foldable upward.

The lower umbrella rib 18 in the illustrated example is expandable and retractable and consists of a cylindrical third umbrella rib 20 and a similarly cylindrical fourth umbrella rib 21 that is slidably fitted into the third umbrella rib 20. It has a plug-in structure. Note that the lower umbrella ribs 18 may be connected with three extendable ribs instead of two as shown in the drawing. Further, the cross section of the lower umbrella rib 18 is not limited to a cylindrical shape, but may also be a quadrangular cross section, a U-shaped cross section, or the like.

Furthermore, the lower umbrella rib may be of a fold-in type structure in which the third umbrella rib and the fourth umbrella rib are connected by a bottle, instead of being of the insertion type as in the embodiment.

As shown in FIG. 6, the upholstery fabric 22 is separate from the umbrella ribs of the upper umbrella rib 9 and the lower umbrella rib 18 and can be removed from the umbrella ribs, and a first shaft handle is provided in the center. The protrusion 8 at the upper end of 2
It has a hole 22a into which it is fitted, and a locking part 22b made of, for example, metal wire, plastic, or thread, is provided on the periphery to be secured to the tip of the lower umbrella rib 18 when it is fully opened during use.

When using the folding umbrella configured as described above, as shown in FIG. The stay 14 and the second stay 15 are extended, and the first umbrella rib 10 and the second umbrella rib of the upper umbrella rib 9 are extended.
The second umbrella rib 181 is extended, and the second lower umbrella rib 18 is folded back and spread out at the hinge mechanism 19, and the fourth umbrella rib 21 is extended from the third umbrella rib 20. The upper umbrella rib 9 spread out in this way
Then, the upholstery fabric 22 shown in FIG. 6 is pasted onto the lower umbrella rib 18. That is, the center hole 22a of the upholstery cloth 22 is fitted into the projection 8 at the upper end of the first shaft handle 2, and the upholstery cloth 22 is inserted into the upper umbrella rib 9.
Then, it is spread out on the lower umbrella rib 18, and the locking portion 22b on the periphery of the upholstery fabric 22 is locked to the tip of the fourth umbrella rib 21 of the lower umbrella rib 18. This results in a state for full use.

When storing this folding umbrella, the first umbrella rib 10 and the second umbrella rib 11 of the upper umbrella rib 9 are slightly reduced, and the stay 13
By slightly reducing the first stay 14 and the second stay 15, the locking portion 22b on the periphery of the upholstery fabric 22 can be easily removed from the tip of the fourth umbrella rib 21, so that the center of the upholstery fabric 22 can be easily removed. Remove the upholstery fabric 22 from the upper umbrella rib 9 and lower umbrella rib 18 by holding it by hand and pulling it up.

Subsequently, the first umbrella rib 10 and the second umbrella rib 11 of the upper umbrella rib 9 are further reduced, and the first stay 14 and the second stay 15 of the stay 13 are further reduced, and the descending hollow 7 is
When pushed up along the shaft handle 2 to the upper wheel 6, the reduced stay 13 is pushed up into the reduced U-shaped groove of the upper umbrella rib 9 (in this case, it is not directly connected to the 2
It is stored in the U-shaped shaft of the umbrella rib 11). Then,
The fourth umbrella rib 21 and the third umbrella rib 20 of the lower umbrella rib 18 are reduced, and the reduced lower umbrella rib 18 is folded upward at the hinge mechanism 19, and the first shaft handle 2 and the third umbrella rib 20 are reduced. When the two-shaft handle 3, the third shaft handle 4, and the fourth shaft handle 5 are sequentially inserted and reduced, as shown in FIG.
Shaft handle 2, second shaft Pyg3. The shaft handle 1 portion consisting of the third shaft handle 4 and the fourth shaft handle 5, the umbrella rib portion consisting of the upper umbrella rib 9 and the lower umbrella rib 18, and the structure portion consisting of the stay portion 13 are assembled into an extremely compact structure. It will be done.

In this way, the space in the U-shaped groove of the upper umbrella rib 9 is effectively utilized, so the upper umbrella rib 9 and the stay 13 in the folded state are compacted, and the structure of the folding umbrella is made sufficiently small. It can be made small enough to be stored in a pocket.

Further, the removed upholstery cloth 22 may be wrapped around the structure portion and stored together with the structure portion, or may be folded and stored separately.

Further, the upholstery cloth 22 is not limited to one that can be used repeatedly, but a disposable one made of a thin resin film can be used.

Note that the lower wheel 7 of the embodiment has an inner diameter that allows it to slide only along the first shaft handle 2, and in this case, when the umbrella is simply closed rather than folded into a stored state, the lower wheel 7
is pushed up along the first shaft handle 2 to close the umbrella rib part (simply close it without reducing it), but the lower part 7 is pushed up to the second shaft handle 3 and then to the third shaft handle 4. It may have a slightly larger inner diameter so that it can be slid along. In this case, the umbrella can be closed by pushing down the bottom wheel 7 in the same way as a normal umbrella.

In addition, in the embodiment, the four shaft handles 2, 3, and 4.5 were connected in a plug-in manner, but as shown in Fig. 9, the lowest shaft handle functions as the original shaft handle. It can also be used as a shaft handle case that also functions as a case to store the folded structure part. That is, for example, a screw 30 is provided on the lower end surface of the insert type shaft handle 4° corresponding to the third shaft handle in FIG. Provided, said screw 3
0 is screwed into the screw 6 31a and fixed, the handle 31 can be used as a shaft handle when holding an umbrella, and when storing the umbrella, the cap 31b is removed and the folded structure part is stored inside. be able to. In this case, it is also possible to wrap the removed upholstery fabric 22 around the structure part and store it in the case 31 that also serves as the shaft handle.

[Effects of the Invention] Since the present invention is configured as described above, it has the following effects.

Since the reduced stay can be stored in the U-shaped groove of the reduced upper umbrella rib, the size of the folded structure can be made sufficiently small, and the upholstery can be removed from the structure. As a result, the entire device can be made extremely small, making it possible to achieve a significant reduction in size to the extent that it can be stored in a pocket or the like.

Further, in the configuration using a case that also serves as a shaft handle, the lowermost shaft handle is effectively used, and the appearance of the folding umbrella in the stored state is improved.
