Description

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

  Conventionally, by opening an umbrella, it has been prevented that the user is directly exposed to rain and sunlight.

  However, it is possible to prevent rain falling from above by opening the umbrella, but at the same time, there is a disadvantage that the air flowing from below cannot be released. When a strong wind such as a building wind blows into the inside of the umbrella, the umbrella is hit by the large area that receives the wind of the umbrella. It is often difficult for a user to hold an umbrella that has been hit by such a strong wind. Moreover, when the force that the umbrella bone receives from the umbrella cloth exceeds the buckling strength of the umbrella bone, the umbrella bone buckles. When more force is applied, all the bones are connected via the umbrella cloth, so the buckling of one bone causes all the bones to buckle, resulting in a dish-shaped umbrella cloth. It will turn over and cause damage to the umbrella. Furthermore, since the air is trapped inside the umbrella, there is a problem that the user feels uncomfortable.

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

Japanese Utility Model Publication 2-66112 Japanese Patent Laid-Open No. 10-66613 JP-A-11-169216 JP-A-11-206429 JP 11-332624 A

  Specifically, the umbrella disclosed in Patent Document 1 is provided with a member having a hole in the vertical direction at the top of the umbrella, thereby allowing the wind to escape to the top of the umbrella and mitigating wind power associated with the umbrella cloth. To do.

  In addition, the umbrella disclosed in Patent Document 2 forms a wind inflow port in the middle pole of the umbrella in the semi-enclosed space of the umbrella, forms a wind outflow port at the upper end of the middle rod, and is near the outflow port. The canopy is to be attached to.

  Moreover, the umbrella currently disclosed by patent document 3 forms an opening in the umbrella cloth near the top part of the umbrella, and a lid made of a waterproof material is bonded on the opening so as to have a part of the opening.

  Moreover, the umbrella currently disclosed by patent document 4 makes a hole near the top part of the umbrella cloth of an umbrella main body, and covers another umbrella cloth so that the said hole may be covered. An elastic body is fixed between the umbrella cloth covering the hole and the main body. When the umbrella is subjected to wind, the umbrella cloth covering the hole is separated from the umbrella cloth of the main body by wind pressure, and an opening through which the wind passes is formed. When the wind stops, the elastic body acts to return the umbrella cloth covering the hole to the state before receiving the wind pressure.

  In addition, the umbrella disclosed in Patent Document 5 is an umbrella cloth having a plurality of holes, which is covered with, for example, an isosceles triangular opening / closing cloth, and two sides of the opening / closing cloth are stretched on the umbrella cloth. We are going to establish.

  However, since the umbrella disclosed in Patent Document 1 has a hole in the vertical direction, rain may enter from the hole. Moreover, since the opening was provided in the top part of the umbrella, there existed a problem that it was difficult to recover | repair the aesthetics which gave the appearance by giving a design etc. while losing aesthetics.

  In addition, the umbrella disclosed in Patent Document 2 cannot obtain sufficient through-flow efficiency because the path through which the wind that flows out from the outlet provided at the top end of the middle rod flows out is complicated. There was a problem.

  In addition, in the umbrellas disclosed in Patent Document 3 and Patent Document 5, the lid adhered near the top of the umbrella is given a certain amount of tension in order to prevent it from drooping due to the weight of rain attached to the surface. Need to be. In other words, the lid does not open unless a force that can counter the tension applied in advance to the lid, and there is a problem in that it has no effect on light winds.

  In addition, the umbrella disclosed in Patent Document 4 does not open the lid unless a force that can counteract the tension of the elastic body is applied, as in the umbrella disclosed in Patent Document 3. There was a problem of having no effect.

  In addition, the umbrellas disclosed in Patent Document 3, Patent Document 4, and Patent Document 5 are not subjected to a complicated process in which an opening is provided on the umbrella cloth and a lid is stretched on each. There was a problem of not becoming.

  Therefore, the present invention has been made in view of such circumstances, has sufficient flow-through efficiency without impairing aesthetics, exhibits sufficient efficacy against light winds, and is complicated. An object of the present invention is to provide an umbrella wheel and an umbrella that can be manufactured without going through the process.

  A potter's wheel according to the present invention is a potter's wheel body that supports the bone of the umbrella, and a flow passage that is formed in the potter's wheel body and penetrates the inner and outer sides of the umbrella, and that is used for air flowing in from one of the flow paths. And a flow path that changes the flow direction and flows out from the other end.

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

  Similarly, for example, by bending the flow path, rain can be prevented from flowing in from the outside of the umbrella.

  Similarly, no pressure is required when air flows out by flowing out of the umbrella through the flow path. That is, even a breeze or the like can easily flow out of the umbrella.

  The flow path formed in the potter's wheel according to the present invention starts from the first flow path starting from the first opening provided on the surface of the potter's body and the second opening provided on the surface of the potter's body. And the second flow path is formed in a substantially bowl shape, and one of the first flow path and the second flow path is the umbrella. It is characterized in that it is formed substantially parallel to the axis.

  According to this configuration, by forming the flow path into a substantially bowl shape, it is possible to reduce the shape loss caused by the shape of the flow path, and to obtain sufficient through-flow efficiency.

  Similarly, since there is no flow path parallel to the axis of the umbrella in the potter's wheel body, a design can be applied to the top part of the potter's wheel body, and the appearance can be prevented from being impaired.

  By forming a potter's wheel with the method described above, it has sufficient flow-through efficiency without losing aesthetics, exhibits sufficient efficacy against light winds, etc., and does not go through complicated steps An umbrella wheel that can be provided can be provided. Similarly, since the swaying of the umbrella due to wind pressure is dramatically reduced, stable walking and harm to the user or other pedestrians by the umbrella can be avoided.

(B) It is sectional drawing which shows the embodiment of the potter's wheel which concerns on this 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 the wind is blowing from the -Y direction toward the Y direction.

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

  The umbrella 1 shown as the first embodiment includes a handle 2 for holding the umbrella 1, an umbrella cloth 3 that prevents the rain from hitting the user by stretching it around the top of the user, and an umbrella cloth 3. By applying tension to the bone 4, the bone 4 that maintains the umbrella cloth 3 in a dish shape, and the umbrella cloth 3 and the bone 4 are gathered and fixed at the center of the umbrella 1, and the wheel body 5, the wheel body 5, and the handle 2 is constituted by an intermediate rod 6 fixed to 2.

  FIG. 2 is a cross-sectional perspective view of the potter's wheel body 5 in the first embodiment.

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

  The bottom surface of the potter's wheel body 5 is formed so as to be in contact with the inside of the umbrella, and the upper part of the top surface and the side surface is formed so as to be in contact with the outside of the umbrella. The flow path 21 is formed in a substantially bowl 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. In addition, the inflow port 24 is formed around the center of the bottom surface of the potter's wheel body 5, the inflow port 24 is the starting point, and is parallel to the axis of the umbrella 1. It is formed near the center of the direction. Furthermore, the outflow port 25 is formed on the surface of the potter's body 5 at the position where the distance from the right-angled portion to the side surface of the potter's wheel body 5 is the shortest.

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

  2 has a substantially trapezoidal cross section in the vertical direction, the shape of the cross section of the potter's wheel body 5 is not necessarily limited to that shown in FIG. Such a standard shape or a deformed shape such as a polygon having no symmetry may be used.

  Next, one end of each bone 4 is inserted into each second groove 23 one by one. 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 in the approximate center of the semicircle. The bone 4 loosely inserted in 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.

  The umbrella cloth 3 is formed by joining together a plurality of pieces 31 made of fabric 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 hypotenuses, and the length of the base is shorter than the length of the hypotenuse. It is formed by joining the oblique sides of the cut pieces 31 with the oblique sides of the adjacent pieces 31. In general, eight pieces of the tops 31 are joined together to form the umbrella cloth 3.

  Next, a mountain shape is formed in the vicinity of the top of the top 31 by folding the vicinity of the top of the top 31 downward, the top of the top is loosely inserted into the first groove 22, and the wire 34 described above is pressed against the top 31. The frame 31 is fixed to the potter's wheel body 5 with.

  In this case, it is preferable that the number of pieces 31 joined and the number of second grooves 23 are the same, and the joint of the pieces 31 and the second grooves 23 coincide with each other in the vertical direction.

  In this case, by forming the distal end of the bone 4 in a substantially semicircular shape, the umbrella cloth 3 can be prevented from being damaged at the portion where the distal end portion of the bone 4 is in contact with the umbrella cloth 3.

  When the umbrella 1 is inserted, when air flows into the inside of the umbrella 1, the air flows upward from the inlet 24 into the flow path 21, the flow direction can be changed at a right angle portion, and the outlet 25 can go to the outside. It will be leaked.

  Moreover, since the flow path 21 is formed in a bowl shape, it has sufficient flow-through efficiency compared to a flow path having a complicated path, and rain can be prevented from entering from the top of the umbrella 1.

  In addition, by not providing the outlet at the top of the potter's wheel body 5, the design can be applied to the upper part of the potter's wheel body 5.

  Similarly, since the horizontal cross-sectional area of the potter's wheel body 5 is larger than that of the potter's wheel provided with the outlet at the top of the potter's wheel, it can sufficiently resist the force in the Y-axis direction applied to the potter's wheel body.

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

  When forming the potter's body 5 using a material having moldability, it is preferable to produce by means of injection molding using a mold. Moreover, when producing using materials with poor moldability, such as wood, it is preferable to produce using drilling means such as a drill.

  Hereinafter, a second embodiment of the potter's wheel according to the present invention will be described.

The first member has a plurality of substantially bowl-shaped first flow passages 53 in the inside thereof in the same manner as the wheel made of one member described above. Further, a screw female member 54 as a connecting means is formed at the bottom of the first member. The flow path 53 is formed so as to have openings at the bottom and side surfaces of the first member 51.

  Further, the second member 52 is arranged in a substantially cylindrical member so that a cylindrical member having a smaller diameter than the member is formed so that a gap 55 as a second flow path is formed between the two members. And it is formed by connecting between two members with a rod-shaped member. Further, a step is formed on the outer periphery of the top surface of the second member 52. A screw male member 56 that can be fixed to the screw female member 54 is provided at the center of the second member.

  Further, the wheel according to the second embodiment is also formed with the first groove 58 and the second groove 59 as in the first embodiment. Since it has the same configuration as the first groove 22 and the second groove 23, no detailed description will be given.

  The first member 51 and the second member 52 are fixed by the screw male member 56 and the screw female member 54, but the umbrella cloth 57 is disposed on the second member 52 before fixing.

  The umbrella cloth 57 is formed by joining a plurality of pieces 60 made of fabric cut into a substantially isosceles triangle 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 hypotenuses, and the length of the base is shorter than the length of the hypotenuse.
