Description

Detailed Description of the Invention (a) Industrial Field of Application The present invention relates to an umbrella with a shaft that extends widely on one side, and in particular, an umbrella that allows the umbrella to open and close smoothly and that prevents the long rib from bending. Regarding the unusually shaped umbrella.

(b) Conventional Technology Firstly, in an umbrella, the supporting ribs connected to the intermediate portions of each main rib are connected to a common potter's wheel that is slidably fitted around the umbrella shaft. The lengths of the main rib and the supporting bone are the same.

(c) Invention tries to solve! By the way, for example, when a person carries luggage and holds an umbrella,
You will be holding the handle of your umbrella in one hand and carrying your luggage in the other. Therefore, the center of the umbrella is at the hand holding the handle, and most of the body and luggage are covered by one side of the umbrella. For this reason, with conventional umbrellas in which the length of the main ribs and the support bones are the same, the essential cargo often gets wet.

Further, for example, in order to prevent the bicycle driver from getting rained on, the umbrella may be fixed to the folded handle or shaft of the umbrella at the handlebar of the bicycle. In this case as well, the driver is covered by one side of the umbrella, so his back and waist are not partially covered, and he is often spared from the rain.

The present invention has been made in consideration of the above circumstances, and
The purpose of the present invention is to provide an oddly shaped umbrella in which the lengths of the ribs are made different so that the umbrella shaft opens wide on one side.

Another object of the present invention is to provide an irregularly shaped umbrella of this kind that can be opened and closed smoothly and has long ribs that are difficult to bend.

(d) Means for solving the 11 problems As a result of intensive study to achieve the above object, the inventor has found that:
The following findings were obtained.

That is, in the umbrella, each rib has a different length, so that the ribs are large on one side of the umbrella shaft. In this case, if the lengths of the main bones are different, if the lengths of the support bones are the same, and each support bone is connected to a common potter's wheel, in the case of the main ribs, the i part is located before the connecting part with the support bones. The ratio of the length of this part to that of the base aS may become larger, and the load acting on the supporting bone may become larger.

For this reason, the frictional resistance between the potter's wheel and the umbrella shaft becomes unbearable, making it difficult to open the umbrella smoothly, and the load concentrated on the connecting part of the main rib to the supporting bone becomes large. Since the length of the tip from the connection part with the bone becomes longer, the bending moment at the connection part of the main rib with the supporting bone is greatly reduced, and the long main bone may become easily bent.

Therefore, as an improvement, the present inventor provided an umbrella shaft with a stone fixed at the upper end and a folded handle at the lower end, and made the lengths of the ribs swingably connected to the upper part of the umbrella shaft to be different. In order to achieve the above purpose, the following measures are taken.

In other words, on the umbrella shaft, one slider is lined up in the axial direction and slidably fitted on the outside, and the potter's wheel is placed on the umbrella shaft on the t3 push handle side of the slider and the white point is slid in the axial direction. 1, and connect one end of the vertebrae of different lengths to the 81I bone, that is, the longer parent bone and the longer culm. Therefore, the bending moment at the joint of the long main bone with the supporting bone is reduced to make it difficult for the long main bone to bend, and −) j, am of each support bone,
- Connect to the slider of 1gs.

In other words, the irregularly shaped umbrella of the present invention is an irregularly shaped umbrella in which the ribs have different lengths so that one side of the umbrella shaft has a large darkness, and improvements thereto.

The irregularly shaped umbrella of the present invention comprises: 1- an umbrella shaft with a stone attached to the end and a folded handle fixed to the lower end; the length of each parent skeleton is connected to one part of the umbrella shaft in a swingable manner; In the case of irregularly shaped umbrellas with different heights, a slider 1@ is fitted onto the umbrella shaft so as to be slidable in the axial direction, and a potter's wheel is slid on the umbrella shaft in the axial direction from the folded handle side of the slider. It is characterized by being able to fit freely on the outside, connecting one end of each support bone with a length corresponding to the length of each main bone, and connecting the other end of each support bone to a slig. That is.

The present invention will be explained in more detail below.The irregularly shaped umbrella of the present invention has an umbrella shaft with a stone fixed to the upper end and a folded handle fixed to the lower end, and is swingable on a part of the umbrella shaft described in I-9. The lengths of the parent skeletons connected to each other are different.

The structure of the umbrella shaft used in the present invention is not particularly limited, and any known one, such as a fixed-form one or a telescopic one, can be used.

In addition, as for the umbrella shaft, there are 7 hooks near the stone base that lock the potter's wheel in the open position when the umbrella is opened, and a closing hook that locks the potter's wheel in the closed position near the folding handle. Seven locking hooks are provided, and each of the 737 locks is provided so that it can be moved in and out between a retracted position stored inside the umbrella shaft and a locking position protruding outside the umbrella shaft. An example of this is one that is equipped with a spring that biases it from the side to the locking position.

In addition, for example, the potter's wheel is provided with a hook for hook 1, and the opening locking hole for locking the umbrella in the open position by inserting the 77th part of the potter's wheel into the vicinity of the stone when the umbrella is opened, is placed near the grip handle. It may also be configured to provide an umbrella closing locking matching hole into which seven hooks of a potter's wheel are inserted to lock the umbrella in the closed position.

Moreover, the structure of the stone peg and handle used in the present invention is not particularly limited, and known ones may be used.

The structure of the main rib used in the present invention is not particularly limited, and it may be shorter than the canopy shaft and formed integrally from the base end to the tip, or it may be formed by two main ribs formed by dividing. It is even better to use a center-folding type rib whose parts are swingably connected to each other. When using a main rib that can be bent in the middle, it is advantageous in that the total length of the main rib can be increased.

In the present invention, the slider is connected to the umbrella shaft via the support bone and the main bone. In the present invention, the slider and the potter's wheel may be integrally connected, or may be constructed of, for example, a wire, a rod, a spring, or the like. Among these configurations, if a spring is provided between the potter's wheel and the slider to bias them toward each other, the potter's wheel and slider can be moved by releasing the locking action of the umbrella closing hook. This is advantageous because the umbrella can be automatically opened by moving the umbrella to the closed position using the biasing force of the spring.

In addition, in the present invention, when a spring is provided between the potter's wheel and the slider to bias them in a direction that separates them from each other, if the locking action of the seven locking locks for opening the umbrella is released, the spring can be attached. This is advantageous because the umbrella can be automatically closed by moving the potter's wheel and the slider to the umbrella closing position by force.

In addition, in the present invention, when the weight is connected to the short main rib, the load distribution around the umbrella shaft can be equalized, and the hand holding the handle can be prevented from being twisted due to uneven weight of the umbrella. It is advantageous because it can be done.

ce＞Function The irregularly shaped umbrella of the present invention includes an umbrella shaft to which a stone is fixed at the upper end and a grip handle at the lower end, and the length of each main rib band that is swingably connected to the upper part of the umbrella shaft is determined. This is because when a person holds an umbrella while carrying luggage, or when a person rides a bicycle while holding an umbrella, the area can be used effectively to prevent the person and luggage from getting wet. be.

Further, in the present invention, one slider is fitted onto the umbrella shaft so as to be slidable in the axial direction, and a potter's wheel is fitted onto the umbrella shaft so as to be slidable in the axial direction on the handle side of the slider, That on each rib! Connect one end of the support bones with different lengths corresponding to the size of the spine, that is, the longer the main bone, the longer the end of the support bone, and connect the other end of each support bone with the slider of 1@ above. By connecting the potter's wheel to the handle, when you push it from the closed position near the grip handle to the dark umbrella position W1 near the stone base, the slider begins to move from the handle side to the stone base position and opens in order from the long rib. In this case, the lengths of each of the supporting bones connected to each main rib are different depending on the length of the main bone, so the longer main bone is connected to the supporting bone at a position far from the proximal end. Therefore, the load acting on the vertebrae can be reduced. As a result, the load acting on the slider via the support bones becomes smaller, and the sliding resistance of the slider becomes smaller, so that the outer rib can be opened easily. In addition, it is possible to reduce the load concentrated on the connection part with the support bone, and also to shorten the length of the main bone beyond the connection part with the support bone, so the bending moment at the connection part of the main bone with the support bone is reduced. The main bone becomes difficult to bend.

(f) Examples The following examples of the present invention are based on the drawings! Although the present invention will be explained in detail, the present invention is not limited thereto.
Figures (A) and #S2 (B) are perspective views showing the framework of a deformed umbrella according to an embodiment of the present invention.

The frame of this irregularly shaped umbrella consists of an umbrella shaft 1, eight ribs 2a to 2e of different lengths which are vertically movably connected to the upper part of the umbrella shaft 1 via a support metal 11, and one end to each of the ribs 2a to 2e. The above-mentioned supports 4a to 4e are connected to one slider 3 whose other end is slidably fitted onto the umbrella shaft 1, and a potter's wheel 5 used for opening and closing the umbrella. There is.

FIG. 3 is a plan view of this umbrella in an open state.

4e [3 is each main rib 2 to which the supporting bones 4a-4e are connected
It is determined corresponding to the length of a to 2e.

In this case, Fig. 2 (A), Fig. 2 (B), and Fig. 4 (
A) ~ As shown in Figure 4 (C), the epithelial bone 4a ~
4e is formed such that each of the main ribs 2a to 2C has a long culm and is extendable and contractible.
The structure may be such that the vertebrae are in an extended state as shown in A), and conversely, in the closed state, the vertebrae are in a contracted state as shown in Figure 2 (B). be. With this configuration, the umbrella can be made compact and convenient to carry.

FIG. 5 is a perspective view of the slider 3, which is externally fitted onto the umbrella shaft 1 so as to be slidable in the axial direction.

This slider 3 includes an annular main body 3Oa, a supporting bone connecting portion 301 protruding from the outer periphery of the main body 3Oa, and a main body 3
It is provided with a rod-shaped series v1 barb 30e extending downward from the left side of the inner circumferential surface of 0a. and,
A potter's wheel locking part 30d that projects in the outer diameter direction is provided at the lower end of each connector 30c.

In addition, between the connectors 30c, there is an umbrella opening locking part 30e that is inserted into a holding hole for opening the umbrella provided in the upper part of the umbrella shaft 1, and is held by a hook 61 supported by the lock o5. is formed.

The potter's wheel 5 is positioned below the lowest slider 3 and is slidably fitted onto the umbrella shaft.

FIG. 6(A) is a perspective view of the potter's wheel, and FIG. 6(B) is a longitudinal sectional view thereof.

The binary potter's wheel 5 is formed in a cylindrical shape, and has a catch 5a on its upper end that receives the main body 30m of the slider 3, and a locking surface that receives the potter's wheel locking part 30d of the varnish rig 3 on its lower end. 5b are formed respectively. A locking member 6 of the umbrella shaft 1 is supported on the front face thereof so as to be swingable in a seesaw manner. Place the potter's wheel 5 on the upper end of this lock 6! Seven hooks 61 are provided through which the umbrella shaft 1 is provided with an umbrella locking hole or an umbrella locking hole for insertion and removal, and an operating portion 62 is formed below the hook. A spring 63 is inserted between the operating portion 62 and the potter's wheel 5 to bias the seven hooks 61 in the engaging direction.

As shown in FIG.
is once elastically deformed inward, and a potter's wheel 5 is fitted underneath it. Thereafter, the umbrella shaft 1 is inserted through the slider 3 and the potter's wheel 5.

In this way, the umbrella shaft]i is attached to the assembled slider 3,
As shown in FIG. 1, the other ends 4e are each connected to the support bones 4a. Then, as shown in Figure 3 (A) and Figure 8 (B), the fabric 7 is stretched over each rib 2m-2e, and a stone stone 8 is placed on the upper end of the umbrella shaft 1, and a stone stone 8 is placed on the lower end of the umbrella shaft 1. The folded handles 9 are assembled on the respective sides.

In this irregularly shaped umbrella, when the irregularly shaped umbrella is closed, the second
As shown in Figures (A) and 8(B), the support bones are in an extended state, and the seven claws 61 of the operating tool 6 are connected to the umbrella closing lever formed near the folding handle 9 of the umbrella shaft 1. It enters the stop hole and is locked.

In this state, when the operating portion 62 of the operating wheel 6 is pressed against the potter's wheel 51II against the spring, the seven hooks 61 exit from the umbrella-closing locking hole, making it possible to push the potter's wheel 5 upward. Then, as shown in FIG. 2(B) and FIG. 8(A), when the potter's wheel 5 is pushed up, the slider 3 is first stopped by the catch seat 5a of the potter's wheel 1115 and pushed up, and the support bone 4a ~4C and the main ribs 2a to 2e are opened, the seven hooks 61 are pushed by a spring into the opening locking hole formed in the umbrella shaft 1 under the circumstances of the stone bolt 8, and are locked in the opening position. will be stopped. In this state, the opening locking portion of the slider 3 is held by the seven hooks 61.

When this umbrella is opened, the ribs 2a to 2e are covered with cloth 7.
The tension acts in the direction of closing the umbrella. Above ribs 2a-2
The tension acting on e is evenly distributed over the entire length of the main ribs 2a to 2e, and the tension that tries to close this umbrella is applied to the main ribs 2a to 2e.
It is shared at two locations: the connection point of the support bones 41 to 4e of 2e and the base end. Here, the load received by the supporting ribs 4a to 4e supporting each of the main ribs 2a to 2e is proportional to the magnitude of the tension of the upholstery 7 that each of the main ribs 28 to 2e receives, and It is inversely proportional to the distance from to the connection point of the support bones 4a to 4e. Therefore, taking a short main rib, for example 2e, as an example, the length of each support bone 4a to 4en and the length of each main rib 2a to
Compared to the conventional example in which the distance from the proximal end of the main ribs 2e to one point of connection with the supporting bones 4a to 4e is the same, the distance from the proximal end of each of the supporting bones 2a to 2e to the supporting bones This umbrella, in which the distance to the connection point with the main ribs 2IL to 4e is determined in accordance with the length of each main rib 2IL to 2e, is better from the proximal end of the main rib 2e to the supporting bone 4e.
The distance to the connection point with the main rib 2e becomes larger, and the load shared by the support bone 4e that supports the main rib 2e becomes smaller. As a result, the load acting on the slider 3 via the support bones 4e is reduced, and the sliding resistance of the slider 3 is reduced, so that the umbrella can be opened easily. In addition, the load is reduced because the long support bones 4e share the load, and the dimensions of the tip of the main rib 2e from the 7 points of connection with the support bones 4e become smaller.
The bending moment acting on the connection point of e with the support bone 4e becomes smaller, making it difficult to bend the long main rib 2e.

The same can be said of the second longest rib 2d or the third longest rib 2c, which is longer than the average length of the ribs 2a to 2e.

In addition, when the irregularly shaped umbrella is closed, when the irregularly shaped umbrella is opened and the operation WS 62 of the operation 6 is pressed against the potter's wheel 51I against the spring 63, the 7 hooks 61 exit from the opening locking hole, and the potter's wheel 5 can be pulled downward. Then, when you lower the potter's wheel 5, first slider 3
is stopped by the catch seat 5a of the potter's wheel 5 due to the tension of the upholstery 7, and begins to be pushed downward, and the support bones 4IL to 4e and V
Bones IIl 2a-2e begin to be ejaculated. When the tension in the upholstery 7 disappears while the umbrella is closed, the locking surface 5b of the potter's wheel 5
sequentially lock the potter's wheel lock 130d of the slider 3 and push it down, and the support ribs 4a to 4e and the master ribs 2a to 2e are closed. In this way, each of the supporting ribs 4a to 4e and main ribs 2a to 2e are closed in order of shortest length, and finally, when each of the supporting bones 4a to 4e and main bones 2a to 2e are completely closed, the seven hooks 61 are placed on the upper side of the grip handle 9. A spring 6 is inserted into the opening locking hole formed in the umbrella shaft 1.
3, the umbrella enters and is locked in the closed position.

In addition, in the above-mentioned one example, according to a modification in which the length of the longest support bone 4e is further increased, the structure may be configured as shown in FIG. 9(A> and FIG. 9(B)). In particular, as shown in FIG. 9(B), an umbrella can be made in which the depth of the umbrella is greatest at the middle part of the longest rib 2e.

Further, in the above-mentioned embodiment, it is also possible to configure the long main rib 2e to be able to be bent in the middle. In this case, it is possible to make the length of the main rib 2e longer than the distance between the stone block 8 and the grip handle 9. In addition, by connecting a weight to the tip of the short main rib 2b to equalize the weight distribution around the umbrella shaft 1 when the umbrella is opened, the hand holding the handle 9 can be twisted due to the uneven weight of the umbrella. This will prevent this from happening, and you will be able to hold your umbrella more easily.

Further, a slider and a potter's wheel for a deformed umbrella according to another embodiment of the present invention will be explained.

In this embodiment, the slider 3 has a main body 30a, a supporting bone connecting portion 30b extending radially outward from the outer circumferential surface of the main body 30g, and an outer circumferential surface of the main body 30&. Contains % 30 e of connections drawn in one direction. and,
The potter's wheel 5 is integrally formed with the slider 3.

Also 11. l: In the embodiment described above, the connecting tool 30e is composed of a rond having a potter's wheel locking part 30cl at the lower end, whereas in this embodiment, the slider 3 and potter's wheel 5 are connected by a pawl that connects the slider 3 and potter's wheel 5. 5 may be biased toward each other.

Other #Il! R is constructed in the same manner as in the above embodiment.

In this embodiment, since the connector 30C brings the slider 3 and the potter's wheel 5 closer to each other when checking the irregular shape rate, the operation 14
: When the operating portion 62 of 6 is pressed against the spring 63 to the potter's wheel s side to release the locking action of the 7 hooks 61, the irregular shape rate is automatically closed.

In this embodiment, Ws is set so that the connector 30e urges the slider 3 and the Zorokuro 5 in the direction 7j to separate them from each other.
If this is the case, the deformed portion can be automatically closed by removing the seven hooks 61 from the opening locking holes.

(g) Effects of the Invention As described above, the irregular shape according to the present invention includes an umbrella shaft to which a stone is fixed to the L end and a handle to the lower end, and is swingably connected to the upper part of the umbrella shaft. Since the lengths of the ribs are different, the area of the umbrella can be used extremely effectively, and as a result, it is useful for people holding luggage and for preventing rain from falling on bicycle drivers. We have it.

Further, in the present invention, one slider is fitted onto the umbrella shaft so as to be slidable in the axial direction of the umbrella shaft, and a slider is fitted onto the umbrella shaft on the grip handle side with respect to the slider in the irregular shape ratio in which the lengths of the ribs are different. Fit the potter's wheel so that it can slide freely in the ring direction, connect one end of each support bone with different lengths corresponding to the length of the master rib, and connect the other end of each support bone to the one slider mentioned above. It is connected to. Therefore, the position from the proximal end of the main rib where the main rib is connected to the support bone is set corresponding to the length of the main bone, and the position where the main bone is connected to the support bone from the proximal end of the main rib is constant regardless of the length of the main bone. Compared to the conventional example, it is possible to reduce the load acting on the support bones connected to the main ribs, reduce the sliding resistance of the slider, and make the umbrella more beautiful! l
In addition, the load acting on the supporting bone connected to the main rib can be reduced, and the length of the distal side from the connection point of the main bone with the supporting bone can be known, so the length of the main bone can be measured. The bending moment at one connection point with the support bone can be reduced,
This makes the main ribs less likely to bend, and durability is significantly improved.
