A plurality of the wall members are alternately arranged on the left and right sides at intervals in the length direction in the wet air flow passage .
In the case of the above ventilator, the ventilation holes are arranged at a position and orientation different from the ventilation part of the body-worn item, so that not only good ventilation is achieved, but also prevention of raindrops when using in rainy weather Is possible. By using such a ventilator, it is possible to easily ventilate a general body-worn item such as clothing, a hat, and shoes at a low cost.
Even if raindrops enter, it is configured to be shielded by the raindrop entry prevention means, so that the entry of raindrops can be minimized.

Another ventilator according to the present invention includes a ventilator main body that closes a ventilation portion of clothing, a hat, shoes, and other body-worn items, and the ventilator main body is a base portion and an abbreviation provided along the surface side of the base. A tube member, and at least a part of the wet air flow passage in the inner space is open to the back side of the base portion, and a vent hole provided in the tube portion so as to communicate with the wet air flow passage. It has. The tube portion is bent at an intermediate portion thereof.
  In the case of the above ventilator, the ventilation holes are arranged at a position and orientation different from the ventilation part of the body-worn item, so that not only good ventilation is achieved, but also prevention of raindrops when using in rainy weather Is possible. By using such a ventilator, it is possible to easily ventilate a general body-worn item such as clothing, a hat, and shoes at a low cost.
Moreover, not only the design is enhanced by the bent portion of the tube portion, but also raindrops that have entered enter the bent portion and can be utilized as means for preventing raindrop entry, which is advantageous.

Preferably, the ventilator body has a configuration in which a plurality of tube portions are arranged.

In the case of the ventilator changed in this way, the opening area of the vent hole can be reduced as the number of tube portions increases, so that it is possible to further prevent raindrops from entering.

Preferably, the ventilator main body has a structure in which a through small hole for promoting ventilation is provided on the outer wall surface of the tube portion.

In the case of the ventilator modified in this way, the ventilation amount can be optimized according to the inner diameter and number of the through holes, so that better ventilation can be realized. The ventilation effect is enhanced.

Preferably, the ventilator main body is configured to have an inclined surface that is inclined to facilitate the inflow of external air and is inclined downward from the open end portion on one side of the tube portion to the closed end portion on the other side. Good.

In the case of the ventilator modified in this way, the structure is such that a negative pressure is caused in the tube portion due to the flow of external air, so that a relatively long time of air flow is maintained, and the ventilation effect is accordingly accompanied. Will increase.

Preferably, the ventilator main body may be configured to use a material that can be sewn in order to adhere around the ventilation portion of the body-worn item.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the ventilation structure α given as an example here is used in the rainwear 100 in order to suppress the internal humidity and the internal temperature of the rainwear 100 (corresponding to a body-worn item) which is a kind of clothes. The formed ventilation part 110 and the ventilator 1 fixed to the surface side of the rainwear 100 so as to close the ventilation part 110 are provided.

About the ventilation part 110, it is a square hole opened in the slightly lower position of the both sides of the rainwear 100 by the example of this plan, Comprising: The mesh is attached to the opening. Moisture (humidity) from the upper limb of the wearer of the rainwear 100 is released to the outside of the rainwear 100 through the ventilation portion 110, or conversely, outside air is taken into the rainwear 100 and ventilation is performed. It has become. The ventilator 1 is fixed around the ventilation part 110 of the rainwear 100 so that such ventilation is performed efficiently. In FIG. 1, only one of the ventilator 1 and the ventilation part 110 is shown.

The ventilator 1 includes a ventilator body 10 that closes the ventilation portion 110. The ventilator main body 10 is translucent so as not to stand out in the present example, and is soft as much as the cloth of the rainwear 100, and a material such as a resin that can be sewn around the ventilation portion 110 of the rainwear 100 is used. Yes. Moreover, what was created integrally using the type | mold is used. In other words, the ventilator body 10 has a shape suitable for making by punching a mold.

The specific fixing method of the ventilator main body 10 is as follows, and is fixed to the rainwear 100 so that the vent hole 13 of the open end 122 of the tube portion 12 to be described later faces downward. Further, the vent hole 13 of the tube portion 12 is fixed to the rainwear 100 with the vent portion 13 being displaced in a direction away from the center O of the vent portion 110 with respect to the vent portion 110.

The configuration of the ventilator body 10 is as follows. That is, as shown in FIG. 2, the main body 10 is a plate-like base portion 11 and a substantially cylindrical member provided in a plurality of arrays along the surface 111 side of the base portion 11 and has an inner space. The tube portion 12 that is exposed and opened from the back surface 112 side of the base portion 11 (see FIG. 2B) and the one end portion 122 in the length direction of the tube portion 12 are opened and moisture is exposed. Ventilation hole 13 provided in communication with one end of flow passage 121, wall member 124 provided in tube portion 12 (corresponding to raindrop intrusion prevention means), and ventilation promotion provided on the outer wall of tube portion 12. And a small through-hole 125 for the purpose.

As shown in FIG. 2B, the base portion 11 is formed corresponding to the tube portion 12 on the frame-shaped edge portion 113, which is a portion sewn using the rainwear 100 and a thread, and the back surface 112 side. Opening 114.

The tube portion 12 is a substantially semi-cylindrical member whose lower surface is released, and as shown in FIG. 2D, one end in the length direction is released while being inclined ( open end portion 122). On the other hand, as shown in FIG. 2C, the other end in the length direction is closed while being curved (closed end 123). The internal space of the tube portion 12 is a wet airflow passage 121. In the present example, as shown in FIG. 2B, the entire wet airflow passage 121 is exposed and released through the opening 114 of the base portion 11. Yes.

Further, on the outer surface of the tube portion 12, as shown in FIG. 2E and the like, an inclined surface 126 inclined downward from the open end portion 122 to the closed end portion 123 in order to facilitate the inflow of external air. Is formed. When a flow of external air is received, a negative pressure is caused in the tube portion 12, and as a result, the air flow is maintained for a relatively long time. About the inclination | tilt angle of the inclined surface 126, it is good to set suitably according to required ventilation.

A plurality (six in this example) of the tube portions 12 having the structure as described above are arranged in the width direction.

The wet air flow passage 121 is a groove portion having a semicircular cross section formed in the length direction on the back side of the tube portion 12, and moisture is released through the vent hole 13 on one end side while external air is taken in. (See FIG. 1).

As shown in FIG. 2B, the wall member 124 is a blade-like member that partially closes the wet airflow passage 121 in the tube portion 12, and in this example, the wall member 124 is alternately left and right at intervals in the length direction. A total of four are arranged.

As described above, the entire wet air flow passage 121 of the tube portion 12 is exposed and released through the opening 114 of the base portion 11. However, in the state where the ventilator 1 is fixed to the rainwear 100, the region from the vent hole 13 to the vent portion 110 in the opening 114 depends on the fabric on the surface side of the rainwear 100 as shown in FIG. It is blocked. Therefore, most of the raindrops that have entered the wet airflow passage 121 from the vent hole 13 are shielded by the wall member 124. Since the wet airflow passage 121 is partially blocked by the wall member 124, the ventilation of the wet airflow passage 121 is not hindered.

As shown in FIGS. 2A and 2B, the through small hole 125 is a hole formed at a position between the vent hole 13 on the outer wall of the tube portion 12 and the wall member 124, and is long in this example. A total of three are arranged at intervals in the vertical direction. It is good to adjust so that a desired internal pressure may be obtained by appropriately setting the hole diameter and number.

In the case of the above-described ventilation structure α, the ventilation section 110 of the rainwear 100 is closed by the ventilator 1 by the ventilator 1, so that good ventilation is realized. The ventilation of the rainwear 100 can be achieved with an effect higher than that of the material. Moreover, since raindrops do not easily enter as will be described later, the inside of the rainwear 100 is not wetted by raindrops, which improves usability. Furthermore, a great merit can be expected in terms of cost in that the ventilator 1 is formed by integral molding and the ventilator 1 can be attached to the 100 by stitching in the flow of a series of 100 manufacturing processes. Is possible.

It is difficult for raindrops to enter the rainwear 100. 1) The ventilation holes 13 are arranged at positions and orientations different from the ventilation portion 110 of the rainwear 100, and 2) the ventilation of the tube portion 12 due to the shape. A point where the opening area of the hole 13 is small, 3) a point where raindrop entry preventing means is provided in each of the tube parts 12, 4) a point where the linear distance between the vent hole 13 and the vent part 110 is long, and 5) This is realized by a combination with the point that the ventilation hole 13 faces downward. In addition, since the wall member 124 is used as raindrop intrusion prevention means, it is possible to prevent raindrops from entering without impeding the ventilation of the wet airflow passage 121, which is of great significance for effective ventilation. There is.

In order to further enhance the effect of preventing raindrop entry, ventilators such as ventilators 1 ′, 1 ″, 1 ′ ″ according to the first, second, and third modifications shown in FIGS. 3 to 5 are used. The design may be changed so that the shape of the intermediate portion 127 of the main body 10 is bent. If the bending direction or the number of the intermediate portions 127 are changed in this way, the way in which raindrops that have entered the wet airflow passage change is changed, so that the effect of preventing raindrops from entering can be further enhanced. In addition, in the said modification, since structures other than the shape of the base part of a ventilator main body and a tube part are completely the same as the said embodiment, it shall abbreviate | omit about the description.

The ventilator and the ventilation structure according to the present invention are not limited to the application of inwear alone, but also other clothing (including innerwear, hooded outerwear, pants, etc.), hats, shoes, etc. It can be similarly applied to general body-mounted products. In this case, the position, shape, etc. of the ventilation part to be formed on the body-worn product may be appropriately selected according to the type of the body decoration, and a mesh fabric or rivet may be provided instead of a simple opening. .

The base part of the ventilator body has an arbitrary shape according to the attachment method to the body ornaments, etc., and the tube part also has the number (one or more), the shape of the cross section (including circular, square, etc.), long Including the shape of the vertical direction (including curves, bends, crosses, etc.), the direction of arrangement (including forms in which all or part of them are arranged in different directions, etc.), the position of the vent holes (forms to be arranged on the side surface of the tube part, etc.) ), The shape and the like may be arbitrarily set similarly. Further, only a part of the inner space of the tube part may be exposed and opened from the back side of the base part, or both ends of the tube part may be opened to form a vent hole. As for raindrop entry prevention means for the tube section, for example, the wet airflow passage itself is curved or bent, a small room for collecting raindrops entering the same passage is provided in the wet airflow passage, or the raindrops are the same. There may be a form in which a route for discharging outside the passage is provided in the wet air flow passage.
