Description

Specification

Potter's wheel and umbrella

Technical field

The present invention relates to a wheel of an umbrella having a ventilation function, and an umbrella.

Background art

[0002] Conventionally, by opening an umbrella, it has been prevented that the user is directly hit by rain or sunlight.

[0003] However, although rainfall from above can be prevented by opening the umbrella, at the same time, there has been a disadvantage that air flowing from below cannot be escaped. If a strong wind such as a building wind blows into the inside of the umbrella, the umbrella will be instigated by the large area that the umbrella receives. It is often difficult for users to hold an umbrella that has been fanned by such strong winds. If the umbrella bone exceeds the buckling strength of the umbrella bone, the umbrella bone will buckle. When additional force is applied, all bones are connected via an umbrella cloth, so buckling of one bone causes buckling of all bones in a chain, resulting in a dish-shaped umbrella cloth. Turns over, causing damage to the umbrella. Further, there is a problem in that air enters inside the umbrella, which causes discomfort to the user.

[0004] As means for solving these problems, Patent Literature 1, Patent Literature 2, Patent Literature 3, Patent Literature 4, and Patent Literature 5 are disclosed.

[0005] Patent Document 1: Japanese Utility Model Application Publication No. 2-66112

Patent Document 2: JP-A-10-66613

Patent Document 3: JP-A-11-169216

Patent Document 4: JP-A-11-206429

Patent Document 5: JP-A-11-332624

[0006] Specifically, the umbrella disclosed in Patent Document 1 allows a wind to escape to the upper part of the umbrella by attaching a member having a hole in a vertical direction to the top of the umbrella, and relates to the umbrella cloth. As to alleviate the wind!

[0007] In addition, the umbrella disclosed in Patent Document 2 is such that wind flows into the center rod of the umbrella in a semi-enclosed space of the umbrella. A mouth is formed, a wind outlet is formed at the top end of the center rod, and a canopy is attached near the outlet.

[0008] Further, the umbrella disclosed in Patent Document 3 has an opening formed in an umbrella cloth near the top of the umbrella, and a lid that also has a waterproof material strength is provided on the opening so as to partially have an opening. Glued.

In the umbrella disclosed in Patent Document 4, a hole is formed near the top of the umbrella cloth of the umbrella body, and another umbrella cloth is further covered so as to cover the hole. An elastic body is fixed between the umbrella cloth covering the hole and the main body. When the umbrella is blown by the wind, the umbrella cloth covering the hole is separated from the umbrella cloth of the main body by the wind pressure, and an opening through which the wind passes is formed. When the wind stops, the elastic body acts, and the umbrella cloth covering the hole returns to the state before receiving the wind pressure.

[0010] Further, the umbrella disclosed in Patent Document 5 is an umbrella cloth having a plurality of holes, in which, for example, an isosceles triangular-shaped opening / closing cloth is placed over the holes, and two sides of the opening / closing cloth are covered with the umbrella. It is to be installed on cloth.

[0011] However, the umbrella disclosed in Patent Document 1 has a hole in the vertical direction, so that rain may enter through the hole. In addition, since the opening is provided at the top of the umbrella, the appearance is impaired, and it is difficult to recover the impaired appearance by applying a design or the like.

[0012] Further, the umbrella disclosed in Patent Document 2 has a sufficient flow-through efficiency because the path from the outflow port provided at the upper end of the middle rod to the outflow of the wind is complicated. I couldn't do it! /, And! /, There was a problem.

[0013] Further, in the umbrellas disclosed in Patent Document 3 and Patent Document 5, the lid adhered to the vicinity of the top of the umbrella is provided with a certain degree to prevent it from hanging down due to the weight of rain attached to the surface. Must be tensioned. In other words, the lid will not open unless a force sufficient to counteract the tension given in advance to the lid, and the lid will not open, and there is a problem that it has no effect on light wind etc. .

[0014] Furthermore, similarly to the umbrella disclosed in Patent Document 3, the umbrella disclosed in Patent Document 4 does not open the lid unless a force sufficient to oppose the tension of the elastic body acts. There is a problem that it has no effect on winds and the like. [0015] Further, the umbrellas disclosed in Patent Document 3, Patent Document 4, and Patent Document 5 are provided with an opening in an umbrella cloth, and a cover is stretched on each of the umbrella cloths.問題 There was a problem that complicated processes had to be performed.

Disclosure of the invention

Therefore, the present invention has been made in view of such circumstances, has sufficient flow-through efficiency without deteriorating aesthetic appearance, and has a sufficient effect even against light winds and the like. It is an object of the present invention to provide an umbrella wheel and an umbrella that can be manufactured without going through complicated steps.

[0017] The wheel according to the present invention is a wheel main body that supports the bone of an umbrella, and a channel formed in the wheel main body that passes through the inside and outside of the umbrella, and that flows in from one of the channels. And a flow path for changing the flow direction of the air and allowing the other end force to flow out.

[0018] According to this configuration, the air that has flowed into the inside of the umbrella can flow out of the umbrella through the flow path connected to the outside of the umbrella.

Similarly, for example, by bending the flow path, it is possible to prevent rain from flowing in from the outside of the umbrella.

[0020] Similarly, since air flows out of the umbrella through the flow path, pressure is not required when air flows out. In other words, even a light wind can easily flow out of the umbrella.

[0021] The flow path formed on the wheel according to the present invention includes a first flow path starting from a first opening provided on the surface of the wheel main body and a second flow path provided on the surface of the wheel main body. A second flow path starting from the opening is continuously connected and formed in a substantially hook shape, and is one of the first flow path or the second flow path. Is formed substantially parallel to the axis of the umbrella.

[0022] According to this configuration, by forming the flow passage in a substantially hook shape, a shape loss caused by the shape of the flow passage can be reduced, and sufficient flow-through efficiency can be obtained.

Similarly, since the wheel main body does not have a flow path parallel to the axis of the umbrella, it is possible to apply a design to the top of the wheel main body, thereby preventing the appearance from being spoiled.

[0024] By forming the potter's wheel by the method described above, a sufficient flow-through effect without impairing the aesthetic appearance is obtained. The present invention can provide an umbrella potter's wheel having a high efficiency, exhibiting sufficient efficacy against a breeze and the like, and capable of being manufactured without going through complicated steps. Similarly, the umbrella flutter caused by wind pressure is revolutionarily reduced, so that stable walking and harm to the user or other pedestrians by the umbrella can be avoided.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

Hereinafter, a first embodiment will be described with reference to the drawings. For convenience of explanation, it is assumed that the XYZ coordinate axes are used, and that the wind is blowing in one Y direction force in the Y direction.

FIG. 1 is a structural diagram of an umbrella shown as a first embodiment.

The umbrella 1 shown as the first embodiment includes a handle 2 for holding the umbrella 1, and an umbrella cloth 3 for preventing rain from hitting the user by stretching the dish over the top of the user. By applying tension to the umbrella cloth 3, the bones 4 that maintain the umbrella cloth 3 in a dish shape, the umbrella cloth 3 and the bones 4 at the center of the umbrella 1 are collected and fixed, and It is composed of a lathe body 5 and a center rod 6 fixed to the handle 2. FIG. 2 is a cross-sectional perspective view of the wheel body 5 according to the first embodiment.

The potter's wheel body 5 has a substantially columnar shape, and includes a plurality of flow paths 21, a first groove 22 formed on the entire surface of the wheel body 5 around the Y axis, and a first channel 22. It is formed by a plurality of second grooves 23 which are orthogonal to the grooves 22 and have a certain width and are formed in the Y direction on the surface of the wheel body 5.

[0032] The bottom surface of the wheel body 5 is formed so as to contact the inside of the umbrella, and the upper surface and the upper part of the side surface are formed so as to contact the outside of the umbrella. The flow path 21 is formed in a substantially hook shape, and has two openings, a wind inlet 24 inside the umbrella cloth 3 formed in a dish shape and a wind outlet 25 outside the umbrella cloth 3. Have. The inflow port 24 is formed around the center of the bottom surface of the wheel body 5. The inflow port 24 is a starting point and is parallel to the axis of the umbrella 1. It is formed near the center in the direction. Furthermore, the outlet 25 is formed on the surface of the wheel body 5 at a location where the distance from the right-angled portion to the side surface of the wheel body 5 is the shortest.

In this case, the flow path 21 is preferably formed, for example, at a right angle. When the flow path 21 continuing through the curved portion of the flow path 21 forms an acute angle, the flow efficiency of air decreases due to the shape loss generated in the curved portion. This is because the flow-through efficiency improves, but rain may enter.

[0034] The potter's wheel main body 5 shown in Fig. 2 has a substantially trapezoidal cross section in the vertical direction. However, the cross section of the potter's wheel main body 5 need not be limited to that shown in Fig. 2. The shape may be a standard shape such as a rectangle or a triangle, or a deformed shape such as a polygon having no symmetry.

Next, one end of each bone 4 is loosely inserted into each of the second grooves 23. At this time, at one end of the bone 4 loosely inserted into the second groove 23, the tip is formed in a substantially semicircular shape, and a through hole 41 is formed substantially in the center of the semicircle. The bone 4 loosely inserted into the second groove 23 is fixed to the potter's wheel body 5 by passing the wire 34 through the through hole 41 and pressing it into the second groove 23.

[0036] The umbrella cloth 3 is formed by joining a plurality of pieces 31 each having a fabric strength and cut into substantially isosceles triangles having water repellency. At this time, it is assumed that one side having a different length is a base and the other two sides are a hypotenuse, and the length of the base is shorter than the length of the hypotenuse. The hypotenuse of the cut piece 31 Is joined to the oblique side of the adjacent frame 31. Generally, top 31

Eight pieces are joined to form umbrella cloth 3.

Next, by folding the vicinity of the top of the top 31 downward, a mountain is formed near the top of the top 31, the top of the top is loosely inserted into the first groove 22, and the above-described wire 34 is attached to the top of the top 31. To fix the top 31 to the wheel body 5.

[0038] In this case, it is preferable that the number of joined frames 31 and the number of second grooves 23 are the same, and the seam of frame 31 and the second groove 23 coincide with each other in the vertical direction. .

In this case, by forming the tip of the bone 4 into a substantially semicircular shape, it is possible to prevent the umbrella cloth 3 from being damaged at a position where the tip of the bone 4 contacts the umbrella cloth 3.

When the air flows into the umbrella 1 while the umbrella 1 is inserted, the air flows upward from the inflow port 24 into the flow path 21, and the flow direction can be changed at a right angle portion. It will flow out of exit 25.

In addition, since the flow path 21 is formed in a hook shape, the flow path has a sufficient flow-through efficiency as compared with a flow path having a complicated path, and prevents entry of rain from the top of the umbrella 1. Can be.

By not providing an outlet at the top of the wheel body 5, the upper part of the wheel body 5 can be designed.

Similarly, since the cross-sectional area in the horizontal direction of the wheel body 5 is larger than that of the wheel provided with an outlet at the top of the wheel, the wheel body 5 has a sufficient resistance to the force in the Y-axis direction applied to the wheel body. You can do it.

The potter's wheel body 5 according to the first embodiment can be produced using a material having a formability of a plastic material or a metal material, or a material having poor moldability such as wood.

[0045] When the potter's wheel body 5 is molded using a material having moldability, it is preferable to produce it by injection molding using a mold. In the case of using a material having poor formability, such as wood, it is preferable to use a drill or other perforating means.

[0107] Similarly, since the cross-sectional area in the horizontal direction of the wheel main body 110 is larger than that of a wheel provided with an outlet at the top of the wheel, the wheel main body 110 sufficiently resists the Y-axis direction force applied to the wheel main body. be able to.

FIG. 9 illustrates an embodiment of the wheel according to the present invention.

FIG. 9 (a) is an elevational view of the wheel main body 120, and FIG. 9 (b) is a cross-sectional view taken along the line AA ′. The potter's wheel body 120 has a substantially conical shape, and a first ventilation hole 121 is formed on the slope in a direction perpendicular to the axis of the umbrella. Further, inside the potter's wheel body 120, the first flow path 121 and the second flow path 122 are connected in a substantially hook shape. The second channel 122 has an inflow port inside an umbrella (not shown).

[0110] The present invention is not limited to the above embodiments. For example, in addition to an umbrella or a parasol, an umbrella for children, an umbrella for adults, an umbrella for sports, an umbrella for leisure, or An umbrella for use such as an umbrella-type tent can be appropriately changed without departing from the spirit of the present invention.

[0111] In particular, the description of the above embodiment is not intended to limit the number and shape of the channels provided on the wheel and the shape and shape of the wheel.
