Summary of invention

However, the main goal of the above ventilation structure is to ensure good ventilation, but it is not considered for use in wet conditions. Therefore, this structure is only suitable for limited use, that is, it is only used for good weather, and the structure is almost difficult to apply to commonly used fitted articles such as other clothing, hats, footwear, and the like.

The present invention has been made in the above circumstances. The invention provides a ventilator and a ventilation structure so that the common fit type article can be smoothly ventilated at a low cost.

The ventilator of the present invention includes a ventilator body adapted to cover a venting opening in one of the fitted articles. The ventilator body includes a base portion having a front side and a back side and a tube body extending along a front surface of the base portion. The tubular body includes a wet air passage that is an internal space of the tubular body and an air hole formed in the tubular body. The air hole communicates with the wet air passage. The base is provided with an opening that allows the tubular body to be at least partially open on the back side of the base.

This ventilator provides good ventilation of the fitted object and prevents water from intruding into the object when it is used in a wet state, since the air hole is disposed at a different position and opening direction than the venting hole of the fitted object. The use of this ventilator provides a simple, low-cost venting of commonly used fit items such as apparel, hats, footwear and the like.

The ventilator body can include a plurality of tubes.

According to this aspect of the invention, an increase in the number of tubes reduces the opening area of the tube, which helps to more reliably prevent water from entering the tube.

The ventilator body may further include a water intrusion prevention means disposed inside the pipe body.

According to this aspect of the invention, the waterproof member can block intrusion of water such that the ventilator can minimize water intrusion.

An embodiment of the waterproof member is a wall for partially blocking the passage of the wet air. A plurality of such walls can be installed inside the pipe body. These walls can be along The longitudinal directions of the tubular bodies are staggered in a manner spaced apart from each other.

According to any aspect of the invention, the ventilator can achieve good ventilation of the fitted article and prevent water from intruding into the fitted article.

The tube body may further include an outer wall having a through hole.

According to this aspect of the invention, the amount of ventilation can be optimized by adjusting the inner diameter, the number of the through holes, or the like. Therefore, the ventilator provides improved and more efficient ventilation for the fitted article.

The tube body may further include: an open end on one of the lengthwise end sides of the tube body, the opening being formed in the open end on the other longitudinal end side of the tube body a closed end and an inclined surface sloped downwardly from the open end to the closed end.

According to this aspect of the invention, the flow of outside air into the tubular body causes a negative pressure in the tubular body. As a result, the air flow can be maintained for a relatively long period of time, thereby enhancing ventilation.

The ventilator body may be made of a sewable material so as to be attachable to the periphery of the venting opening of the fitted article.

The ventilator according to this aspect of the invention has a cost advantage because it can be easily and reliably attached to a fitted article.

The tube body is bendable in the middle portion.

According to this aspect of the invention, the curved portion of the tubular body makes the ventilator more attractive. The curved portion of the tubular body can also be used to collect the water-repellent members of the water entering the tubular body.

The venting structure of the present invention includes a venting hole formed in a fitted article for maintaining a low humidity inside the fitted article; and A ventilator as claimed in any of the aspects of the invention. The ventilator can be secured to the fitted article to cover the vent.

According to this aspect of the invention, the ventilator covers the venting opening of the fitted article. A venting structure similar to the ventilator described above allows for proper ventilation of the fitted article and mitigates the problem of water intrusion into the article during wet conditions. As a result, the venting structure can provide simple ventilation at low cost to commonly used fit items such as garments, hats, footwear, and the like.

The ventilator body can be fixed to the fitted article such that the air hole of the tubular body is open downward.

According to this aspect of the invention, since the air holes of the pipe body are opened downward, raindrops dropped from above cannot enter the pipe body through the air holes. Therefore, the venting structure can further prevent water from intruding into the pipe body.

If the wet air passage of the tubular body is completely open on the back side of the base, the ventilator body can be fixed to the fitted article such that the air holes of the tubular body are spaced from the venting opening.

According to this aspect of the invention, the air hole of the ventilator is spaced from the venting opening of the fitted article, so that the venting structure can more effectively prevent water from intruding into the fitted article.

Detailed description of the preferred embodiment

Exemplary embodiments of the present invention are described below with reference to Figures 1 through 2J. As shown in Fig. 1, the ventilation structure α exemplified herein includes a pair of ventilation holes 110 formed in the raincoat 100, and the raincoat 100 is a garment (corresponding to a fitted object) adapted to keep the inside of the raincoat 100 low. The humidity and temperature, and a pair of ventilators 1 are fixed to the outer surface of the raincoat 100 so as to cover the vent holes 110. It should be noted that FIG. 1 only illustrates the connection with one of the vents 110. A ventilator 1, and the following description of one of the ventilators 1 and one of the venting holes 110 is for ease of explanation.

In this embodiment, the venting opening 110 of the ventilator 1 is comprised of a rectangular opening that is open at a distance below the lower portion of the raincoat 100 and a piece of mesh cloth that is attached to the edge of the rectangular opening to cover the hole. Ventilation is achieved by releasing water (humidity) discharged from the upper body of the wearer of the raincoat 100 through the vent 110 and allowing outside air to enter the raincoat 100 through the vent 110. This ventilation is by means of a ventilator 1 fixed around the venting opening 110 of the raincoat 100.

The ventilator 1 includes a ventilator body 10 that can cover the vents 110. The ventilator body 10 of this embodiment is constructed of a translucent material, such as a synthetic resin that is visually inconspicuous. The material is as flexible (soft) as the fabric forming raincoat 100 and can be sewn around the venting opening 110 of the raincoat 100. The ventilator body 10 is manufactured integrally with a mold. In other words, the ventilator body 10 has a shape suitable for being formed by a press method.

The ventilator body 10 is secured to the raincoat 100 such that the air holes 13 at the open end 122 of the tubular body 12 (which will be described) are open outwardly, i.e., in the direction of the rain. The ventilator body 10 is fixed to the raincoat 100 such that the air hole 13 of the pipe body 12 is offset from the center point O of the vent hole 110. In other words, the ventilator body 10 can be attached to any location of the raincoat 100 as long as the air holes 13 of the tubular body 12 are positioned at a distance from the venting opening 110.

The ventilator body 10 includes a plate-like base portion 11, a plurality of pipe bodies 12, a plurality of air holes 13, a plurality of wall bodies 124 (corresponding to a water-repellent member), and a plurality of through holes 125, as shown in Figs. 2A to 2J. Shown.

The base 11 includes a front surface 111, a back surface 112, a frame-like edge 113 (refer to FIG. 2B), and a plurality of openings 114. The front side 111 of the base 11 is provided with a plurality of tubes 12 that are laterally aligned along the base. In this particular embodiment, there are six laterally aligned tubes 12. The plurality of openings 114 are through holes from the front side to the back side of the base portion 11, and are arranged in line with the tube body 12. The edge 113 is sewn to the raincoat 100 with a thin thread or the like.

Each tubular body 12 is a generally tubular-like member that is longitudinally cut in half and has an opening 114 that is open on the back side 112 side of the base 11. As shown in FIGS. 2D, 2E, and 2F, the longitudinal end (open end 122) of each tubular body 12 has a chamfered opening (air hole 13). As shown in Figs. 2C, 2E, and 2F, the other longitudinal end (closed end 123) of the tubular body 12 is curved and closed.

The space inside each of the tubes 12 forms a wet air passage 121. The wet air passage 121 extends along the longitudinal direction of the tubular body 12. In this embodiment, as shown in Fig. 2B, the tubular body 12 (wet air passage 121) is all open, like the opening 11 of the base portion 11 on the back side of the base portion 11. The air holes 13 at the open end 122 of the tubular body 12 each communicate with the end of the associated wet air passage 121. The end of the wet air passage 121 releases the humidity through the air hole 13 and draws in the outside air (refer to Fig. 1).

A wall 124 is provided to each of the tubes 12. As shown in FIG. 2B, the wall 124 is a blade that partially blocks the wet air passage 121 inside the tubular body 12. In this embodiment, each of the tubular bodies 12 has a total of four walls 124 which are alternately arranged left and right and are disposed longitudinally spaced apart from the interior of the tubular body 12 (in the longitudinal direction of the tubular body 12 in the tubular body) Staggered in a way that is separated from each other). A tubular body 12 having at least one wall 124 can be formed.

The wet air passages 121 of the tubular body 12 are all open, like the opening 114 of the base 11, as described above. It should be noted that, as shown in Fig. 1, when there is a ventilator 1 fixed to the raincoat 100, the area of the opening 114 between the air hole 13 and the vent hole 110 is covered by the front surface of the raincoat 100 fabric. The remaining area of the opening 114 (the area facing the vent 110) communicates with the vent 110. The wall 124 serves to block most of the water entering the wet air passage 121 from the air holes 13. However, since the wall 124 only partially blocks the wet air passage 121, they do not inhibit the air circulation of the wet air passage 121.

Each of the tubular bodies 12 also has an inclined surface 126 as shown in Fig. 2E which is inclined downwardly from the open end 122 to the closed end 123 for assisting inhalation of outside air. The external air received at the inclined surface 126 causes a negative pressure inside the tubular body 12, with the result that the airflow can be maintained for a relatively long period of time. The angle of inclination of the inclined surface 126 can be set according to how much ventilation is desirable.

A plurality of through holes 125 (perforations) are formed in the outer wall of each of the tubes 12 for assisting ventilation, and more particularly between the air holes 13 and the wall 124, as shown in Figs. 2A and 2B. In this particular embodiment, each tubular body 12 has a total of three through holes 125 that are longitudinally spaced apart from the tubular body 12. The diameter and number of each of the through holes 125 can be appropriately set to achieve a desired internal pressure of the wet air passage 121.

The venting structure α has a ventilator 1 that can cover the venting opening 110 of the raincoat 100, and the raincoat 100 can smoothly provide more efficient ventilation than the ventilation provided by the conventional permeable raincoat. In addition, the structure a keeps the interior of the raincoat 100 dry and comfortable because it is not harmful to water intrusion as detailed below. The venting structure a also has a significant cost advantage because the ventilators 1 are formed in one piece and can be attached to the raincoat 100 with a tailor during the production of the raincoat 100.

The ventilation structure α is not harmful to water intrusion (for example, raindrops) by combining the following features (1) to (5): (1) the air holes 13 are disposed at different positions and the opening direction is different from the ventilation holes 110 of the raincoat 100. (2) The shape of the pipe body 12 is made into an air hole 13 having a relatively small opening area; (3) the pipe body 12 is each provided with a water-repellent member; (4) a linear distance from the air hole 13 to the associated vent hole 110; Relatively long; and (5) when the user puts on the raincoat 100, the air holes 13 are all open downward.

Further, the wall 124 serving as the waterproof member can prevent water from invading without suppressing air circulation of the wet air passage 121.

In order to further enhance the waterproofing effect, the ventilator body 10 may be designed to also have a curved intermediate portion 127 (bent once or twice or more in a zigzag shape) as shown in Figures 3 through 5. The ventilators 1', 1", 1"' of the first, second and third modified embodiments. How to collect the water system that has entered the wet air passage 121 depends on the direction or the number of bends of the intermediate portion 127, thus changing These factors can further enhance the waterproof intrusion effect. The configuration of the above-described modified embodiment is basically the same as the foregoing specific embodiment except for the intermediate portion 127 of the ventilator main body 10, and therefore will not be described.

The ventilator and venting structure of the present invention can be applied not only to raincoats, but also to any other commonly used fit items (for example, underwear and other garments, including hooded jackets, pants, etc., hats and footwear). The position of the vent hole to be formed in the object can be appropriately selected according to the type of such a fitted object Settings, shapes and other configurations. The venting opening can be changed to only the opening, plus the opening of a piece of mesh cloth, or an opening reinforced with a grommet-like member. The venting structure can include at least one venting aperture and at least one ventilator.

The base of the ventilator body can be modified into different shapes and designs depending on how it is attached to the fitted article. For example, the base can be modified such that its edges are more suitable for attachment to the shape of the fitted article by thermal compression bonding. Any number (one, two or more) of tubes can be installed. The shape of the tubular body can be modified to have a circular, square or any other shape of cross section. The longitudinal shape of the tubular body can be modified to have an arc, bend, serration, cross or any other shape. The directions of the tubes may all be the same, and some or all of the tubes may be oriented differently. The air holes of the pipe body may be formed beside or any other part of the pipe body. The inner space of the tubular body may be completely open or partially open on the back side of the base (i.e., the opening of the base is formed as a partial opening of the tubular body). The longitudinal ends of the tubular body may be open to form air holes. The pipe body does not have to include a waterproof member. The waterproof member may be a curved or curved wet air passage itself used as a water-repellent member, or a compartment provided in the passage or the like for collecting intrusive water, or a passage provided in the passage for draining To the outside.
