Description

  The present invention relates to a clothes fan.

  In recent years, clothes equipped with a fan for blowing air have been used for the purpose of giving a wearer a refreshing feeling. Clothes having a fan are worn by workers who work in a high-temperature environment, and are therefore mainly distributed in the form of work clothes. An opening for attaching a fan is provided in a garment provided with a fan, and an electric fan (hereinafter, referred to as “clothes fan”) is attached to the opening (for example, see Patent Document 1-2). reference).

Patent No. 4399765 Japanese Patent No. 6200606

  A garment fan includes, for example, fitting a fan main body into the circular opening provided in the garment from the outside of the garment, and then screwing an annular fixing member into the male screw of the fan main body from the inside of the garment. The edge of the opening is sandwiched between the flange of the fan body and the fixing member, and is fixed to the clothes. In the case of a clothes fan that is fixed to clothes in this manner, the fixing member that is screwed into the fan body has the same outer diameter as the fan body, and is screwed into the male screw provided in the fan body. The inner peripheral surface has a female screw to be used. Therefore, in order to prevent the clothes fan from falling out of the opening of the clothes, it is important to prevent the edge of the opening from coming off between the fan body and the fixing member.

  However, when the wearer performs the work, a change in the posture of the wearer due to the work exerts a force on the clothes in various directions. Therefore, when such a force is applied to the vicinity of the opening of the clothes, the edge of the opening may come off between the fan body and the fixing member, and the clothes fan may drop from the opening of the clothes.

  Then, this application makes it a subject to provide the clothes fan which does not fall off easily from the opening part of clothes.

  In order to solve the above problems, in the present invention, the clothes fan is provided with an engaging portion that engages with a peripheral edge portion formed along the edge of the opening of the clothes.

  More specifically, the present invention relates to a garment fan mounted on an opening of a garment, the fan main body having a built-in electric fan and having a flange portion in contact with the periphery of the opening, and the fan main body. And a fixing member that comes into contact with the flange portion through a region around the opening of the garment, and at least one of the fixing member and the flange portion is formed toward the other, It has an engaging part which engages with a peripheral part formed along the edge of the part.

Here, the opening of the garment is a hole of the garment provided for mounting the garment fan, and has a peripheral portion thicker than the surroundings along the edge of the opening. Since this peripheral portion is formed within a range of, for example, several mm to ten and several mm from the end of the clothing in the opening, a step is formed between the peripheral portion and its outer side (outer peripheral side). . Further, “engagement” is a concept in which one member comes into contact with the other when the members relatively move, and does not include fastening by sandwiching the members. Further, the term "engage" is a concept including that it can be engaged when a force in a pulling direction is applied to the cloth of clothes, and when the fixing member is screwed into the fan body, the peripheral edge portion immediately engages with the engaging portion. It is not a concept intended to be done.

  In the above-mentioned clothes fan, at least one of the fixing member and the flange portion is provided with the engaging portion formed toward the other, so that a force in the pulling direction is generated around the opening of the clothes. Even if added, the peripheral portion engages with the engaging portion. Therefore, the edge of the opening is unlikely to come off between the fixing member and the flange. Therefore, the clothes fan does not easily fall off the opening of the clothes.

  In addition, the engaging portion may be formed toward the other at a position located at a predetermined distance from the edge of the opening. Here, the predetermined distance is a distance from the edge of the opening to the engaging portion when the clothes fan is fixed to the opening, and is, for example, larger than the width of the peripheral portion provided in the opening. Great distance. If the engaging portion is provided at such a position, the engaging fan engages with the peripheral edge portion when a force in the pulling direction is applied to the periphery of the opening portion, so that the clothes fan is not attached to the clothes. Does not easily fall from the opening.

  In addition, the peripheral portion is provided in a range inside a predetermined distance from the edge of the opening and may be a portion thicker than the cloth of the clothes. Here, being thicker than the cloth of the garment is a concept that defines the relative thickness around the opening, and for example, the peripheral portion is thicker than the thickness of the cloth at the cuffs of the garment far from the opening. It is not a concept that defines things. If such a peripheral edge portion is formed, when a force in the pulling direction is applied around the opening, the peripheral edge portion engages with the engaging portion by the contact of the peripheral edge portion with the engaging portion. Therefore, the clothes fan does not easily come off from the opening of the clothes.

  Further, the engaging portion may be provided at least along the outer peripheral edge of the fixing member. If the engaging portion is provided along the outer peripheral edge of the fixing member, the peripheral edge portion can be more reliably engaged with the engaging portion, so that the clothes fan does not easily drop from the opening of the clothes.

  Further, the engagement portion may be provided at least along the outer peripheral edge of the flange portion. If the engaging portion is provided along the outer peripheral edge of the flange portion, more reliable engagement of the peripheral edge portion with the engaging portion is possible, so that the clothes fan does not easily fall from the opening of the clothes.

  Further, the engagement portion may include protrusions that are discretely arranged. If such a protrusion is provided, the protrusion contacts the peripheral portion, so that the clothes fan does not easily drop from the opening of the clothes.

  Further, the engaging portion may include fine irregularities. If such unevenness is provided, when a force in the pulling direction is applied around the opening, the peripheral edge engages with the engaging portion due to the contact of the peripheral edge with the unevenness. Fan does not easily fall out of the clothing opening.

  Further, the engagement portion may include a rubber slip stopper. With such an engaging portion, when a force in the pulling direction is applied around the opening, the movement of the peripheral portion is blocked by the frictional force of the rubber, so that the clothes fan can easily move from the opening of the clothes. Do not fall into.

  The above-mentioned clothes fan does not easily fall out of the opening of the clothes.

  Hereinafter, embodiments of the present invention will be described. The embodiment described below is an example of the embodiment of the present invention, and the technical scope of the present invention is not limited to the following modes.

  FIG. 1 is a perspective view showing a clothes fan according to this embodiment. The garment fan 1 is a device that is mounted in a circular opening 42 provided in the cloth 41 that constitutes the garment 4, and is a fan main body 2 having an electric fan built therein, and a fixing screwed to the fan main body 2. And a member 3. In the clothes fan 1, the fan main body 2 is inserted into the opening 42 from the outside of the clothes 4, and the fixing member 3 is screwed into the fan main body 2 from the inside of the clothes 4. First, the fan body 2 will be described, and then the fixing member 3 will be described.

  The fan main body 2 has a housing 21 having a generally hemispherical or dome-shaped appearance that is line-symmetric with respect to the rotation axis of the built-in fan. A substantially flat portion corresponding to an aspherical surface portion of the hemisphere is the front surface of the housing 21, and faces the outer side of the clothes 4 when the clothes fan 1 is attached to the opening 42. A flange portion 27 that forms the outermost peripheral edge portion when the housing 21 is viewed from the front surface is provided on the edge of the front surface portion of the housing 21. Since the flange portion 27 has an outer diameter slightly larger than the inner diameter of the opening portion 42, the periphery of the opening portion 42 is contacted from the outside of the clothes 4 when the clothes fan 1 is attached to the opening portion 42. can do.

  Further, the housing 21 has a male screw 24 at a portion corresponding to the edge of the spherical surface in the hemisphere. The outer diameter of the male screw 24 is smaller than the inner diameter of the opening 42. Therefore, when the clothes fan 1 is attached to the opening 42, the male screw 24 portion fits inside the opening 42.

  In addition, the housing 21 has a lattice-shaped structure as a whole so that the airflow generated by the built-in fan circulates inside and outside the housing 21. Then, the fan built in the housing 21 blows air from the outside to the inside of the clothes 4. Therefore, the gap of the lattice forming the front surface side of the housing 21 becomes the intake port 22. In addition, the gap of the lattice forming the rear surface side of the housing 21 becomes the exhaust port 23.

  Further, the fan body 2 is provided with a slip stopper 28 having fine irregularities. This slip stopper 28 prevents the hand of the person holding the fan main body 2 from slipping when the clothes fan 1 is attached to the opening 42.

Next, the fixing member 3 will be described. The fixing member 3 includes an annular ring portion 31, a slip stopper 32 that is a streak-like protrusion that is discretely arranged in the circumferential direction on the outer peripheral surface of the ring portion 31, and a female screw formed on the inner peripheral surface of the ring portion 31. 33 and 33. The inner diameter of the female screw 33 is substantially equal to the outer diameter of the male screw 24. Therefore, the female screw 33 can be screwed into the male screw 24. The outer diameter of the ring portion 31 is slightly larger than the inner diameter of the opening 42. Therefore, when the female screw 33 is screwed into the male screw 24 while the fan body 2 is in the opening 42, the ring portion 31 causes the portion around the opening 42 to move toward the flange portion 27 side of the fan body 2. It will be pressed.

  Next, the clothes 4 to which the clothes fan 1 is fixed will be described. The garment 4 is provided with a peripheral edge portion 43 along the peripheral edge of the opening 42. The peripheral portion 43 is provided for the purpose of preventing the cloth 41 from tearing from the edge of the opening 42, and is thicker than the surroundings by sewing so-called bias tape, so that the peripheral thick portion is substantially annular. To form. Then, the thick portion forms a step between the thick portion and its surroundings. Although not shown in FIG. 1, a reinforcing material made of a resin plate material is laminated around the opening 42 to prevent the diameter of the opening 42 from expanding due to the expansion of the cloth 41. ing. Instead of the bias tape, for example, a rubber material, a patch, an annular resin or metal, or other various members may be applied to the peripheral portion 43.

  FIG. 2 is a perspective view showing the clothes fan 1 according to this embodiment from a direction different from that in FIG. In FIG. 2, the clothes 4 are not shown. As can be seen from FIG. 2, the fixing member 3 has an annular pressing surface 34 formed continuously along the inner peripheral edge of the fixing member 3 and projections 35 discretely arranged along the outer peripheral edge of the fixing member 3. (Which is an example of the “engagement portion” in the present application) is provided. As can be seen from FIG. 2, the pressing surface 34 and the protrusion 35 are located at positions to face the flange portion 27 when the male screw 24 of the fan body 2 and the female screw 33 of the fixing member 3 are screwed together. It is provided. The flange portion 27 has an outer diameter that is slightly larger than the inner diameter of the opening portion 42, and when the clothes fan 1 is attached to the opening portion 42, the flange portion 27 surrounds the opening portion 42 from outside the clothes 4. Since they come into contact with each other, when the female screw 33 of the fixing member 3 is screwed into the male screw 24 of the fan main body 2, the pressing surface 34 presses the periphery of the opening 42 against the flange 27, and the projection 35 is Is in contact with the cloth 41, or the gap between the tip and the cloth 41 is equal to or less than the height of the step between the peripheral portion 43 and the cloth 41. That is, the tip of the protrusion 35 does not press the cloth 41, but comes to a position where the cloth 41 is touched or a position before the cloth 41 is touched. Therefore, the protrusion 35 does not damage the cloth 41.

  FIG. 3 is a perspective view of the fixing member 3. As can be seen from FIG. 3, the plurality of protrusions 35 are provided on the circumference along the outer peripheral edge of the fixing member 3 at equal angular pitches with the center of the circle as a reference point. The angular pitch between the projections 35 depends on the strength of the cloth 41, but if the diameter of the opening 42 is about 90 mm, it is desirable to set it to about 22.5 degrees. Is about 20 mm.

  As can be seen from the partially enlarged view of FIG. 3, the protrusion 35 obliquely protrudes toward the center of the fixing member 3 when the male screw 24 of the fan body 2 and the female screw 33 of the fixing member 3 are screwed together. It is in the form. Since the protrusion 35 is formed in this manner, the male screw 24 of the fan body 2 is screwed to the female screw 33 of the fixing member 3 with an appropriate strength when the fan body 2 is set in the opening 42 of the clothes 4. When combined, the following contact is made with the periphery of the opening 42.

FIG. 4 is a diagram showing a state in which the clothes fan 1 is fixed to the clothes 4. When the female screw 33 of the fixing member 3 is screwed to the male screw 24 of the fan body 2 with a proper strength in a state where the fan body 2 is set in the opening 42 of the clothes 4, the protrusion 35 is formed as shown in FIG. As described above, at a position located at a predetermined distance t from the edge of the opening 42, the flange portion 27 is projected. The predetermined distance t is a distance longer than the length of the peripheral edge portion 43 in the direction from the edge of the opening portion 42 toward the radial direction of the opening portion 42. For example, the peripheral edge portion 43 has a width of 7 mm at the edge of the opening portion 42. If it is formed in an annular shape, the distance is longer than 7 mm (for example, 8 mm). Since the protrusion 35 is provided at such a position, the protruding end of the protrusion 35 contacts the cloth 41 at a position outside (periphery side) the peripheral portion 43 around the opening 42. The protrusion 35 is formed obliquely toward the center of the fixing member 3, so that the protrusion end of the protrusion 35 faces the peripheral edge portion 43 at a position outside the peripheral edge portion 43.

  Since the clothes fan 1 is configured as described above, a change in the posture of the wearer of the clothes fan 1 applies a force in the pulling direction to the cloth 41 of the clothes 4 so that the cloth 41 is fixed to the flange portion 27. Even if it moves relative to the member 3, the peripheral edge portion 43 contacts the protrusion 35. Then, when the peripheral edge portion 43 comes into contact with the protrusion 35, the periphery of the opening portion 42 cannot expand further in the pulling direction. Therefore, the peripheral portion 43 is engaged with the protrusion 35, and the deformation of the opening 42 in the pulling direction is prevented by the protrusion 35. As a result, the possibility that the edge of the opening 42 comes off between the flange portion 27 of the fan body 2 and the fixing member 3 is suppressed as much as possible. In particular, since the protrusion 35 is obliquely formed near the center of the fixing member 3, the protrusion end of the protrusion 35 faces the peripheral edge portion 43 at a position outside the peripheral edge portion 43. When a force in the pulling direction is applied to the cloth 41 and the peripheral edge portion 43 comes into contact with the protruding end of the protrusion 35, the protruding direction of the protrusion 35 and the moving direction of the peripheral edge portion 43 are in a state of being slightly opposed to each other. Therefore, it is difficult for the peripheral edge portion 43 to pass through between the projection 35 and the flange portion 27, and the periphery of the opening portion 42 does not expand further in the pulling direction. Since the periphery of the opening 42 does not spread in the pulling direction, the diameter of the opening 42 does not increase due to deterioration of the cloth 41 due to repeated use of the clothes 4.

  FIG. 5 is a perspective view showing a first modified example of the clothes fan 1. In the above-described embodiment, the protrusion 35 is formed so as to project obliquely toward the center of the fixing member 3, but the clothing fan 1 is not limited to such a form. In the clothes fan 1, for example, as shown in FIG. 5, the protrusions 35 may be formed so as to project straightly with respect to the flange portion 27 rather than obliquely. Even with the projection 35 having such a configuration, when a force in the pulling direction is applied to the cloth 41 around the opening 42, the peripheral edge portion 43 is engaged with the projection 35, and is moved in the pulling direction at the opening 42. Is prevented by the protrusion 35.

  FIG. 6 is a perspective view showing a second modified example of the clothes fan 1. In FIG. 3, the projections 35 having protrusions each having a constant lateral width are arranged in a discrete manner, but the projections 35 are not limited to such a form. The protrusions 35 may be discretely arranged in a hemispherical shape along the outer peripheral edge of the fixing member 3, as shown in FIG. 6, for example. Even if the projection 35 has a hemispherical shape, the projection 35 can prevent the deformation of the opening 42 in the pulling direction because the projection end of the projection 35 can contact the peripheral portion 43. As a result, the possibility that the edge of the opening 42 is disengaged from between the flange portion 27 of the fan body 2 and the fixing member 3 is further suppressed.

  FIG. 7 is a perspective view showing a third modification of the clothes fan 1. In FIG. 3, the arcuate projection 35 along the outer peripheral edge of the fixing member 3 is illustrated with a flat tip, but the projection 35 is not limited to such a shape. For example, as shown in FIG. 7, the protrusion 35 may have a rounded tip. If the projection 35 has a rounded tip, when the female screw 33 of the fixing member 3 is screwed into the male screw 24 of the fan main body 2, the surface of the cloth 41 is not removed even if the projection 35 is in contact with the cloth 41. Since it is slippery, it can be screwed smoothly. Even with the projection 35 having such a configuration, when a force is applied to the opening 42 in the pulling direction, the peripheral edge 43 is engaged with the projection 35, and the opening 42 is deformed in the pulling direction. Are blocked by the protrusion 35.

  By the way, in the above-described embodiment and modified examples, the projections 35 provided on the fixing member 3 engage with the peripheral edge portion 43, but the means for engaging the peripheral edge portion 43 is provided on the flange portion 27. It may be provided, or may be provided on both the fixing member 3 and the flange portion 27.

  FIG. 8 is a diagram showing a fourth modified example of the clothes fan 1. The garment fan 1 may be provided with a protrusion 29 provided on the flange portion 27 instead of the protrusion 35 provided on the fixing member 3. In this case, the protrusion 29 has a form protruding toward the fixing member 3 at a position at a predetermined distance from the edge of the opening 42, like the protrusion 35. If such a protrusion 29 is provided, when a force in the pulling direction is applied to the cloth 41 of the garment 4 due to a change in the posture of the wearer of the clothes fan 1, the peripheral edge portion 43 contacts the protrusion 29. When the peripheral edge 43 comes into contact with the protrusion 29, the periphery of the opening 42 cannot expand further in the pulling direction. That is, the engagement of the peripheral edge portion 43 with the protrusion 29 prevents the opening portion 42 from being deformed in the pulling direction.

  FIG. 9 is a diagram showing a fifth modified example of the clothes fan 1. The clothes fan 1 may include both the protrusion 35 provided on the fixing member 3 and the protrusion 29 provided on the flange portion 27. If both the protrusions 35 and the protrusions 29 are provided, when a force in the pulling direction is applied to the cloth 41 of the clothes 4 due to a change in the posture of the wearer of the clothes fan 1, the peripheral edge portion 43 causes the protrusions 35 and the protrusions 29. Touch both. When the peripheral edge 43 contacts both the protrusion 35 and the protrusion 29, the periphery of the opening 42 cannot be further expanded in the pulling direction. Therefore, the deformation of the opening 42 in the pulling direction is more reliably prevented by both the protrusion 35 and the protrusion 29. That is, the engagement of the protrusions 29 and the protrusions 35 of the peripheral edge portion 43 prevents the deformation of the opening portion 42 in the pulling direction. In this case, whether or not the projections 29 and 35 have a positional relationship of facing each other depends on the distance between the projections 29, the distance between the projections 35, and the relative relationship between the fan body 2 and the fixing member 3 in the screwed state. Although depending on the orientation, the function of preventing the deformation of the opening 42 in the pulling direction is exerted regardless of whether or not the projection 29 and the projection 35 are in a facing positional relationship.

  Further, in the above-described embodiment and modification, the protrusion is illustrated as the means for engaging the peripheral edge portion 43, but the means for engaging the peripheral edge portion 43 is not limited to the protrusion.

  FIG. 10 is a diagram showing a sixth modified example of the clothes fan 1. The clothing fan 1 may be provided with fine irregularities 29A and 35A (which is an example of the “engagement portion” in the present application) instead of the protrusions 29 and 35 described above. Both the unevenness 29A and the unevenness 35A may be provided on the clothing fan 1, or only one of them may be provided. Even with minute irregularities such as the irregularities 29A and the irregularities 35A, when a force in the pulling direction is applied to the cloth 41 of the garment 4 due to a change in the posture of the wearer of the clothing fan 1, the irregularities 29A on the peripheral edge portion 43, Due to the contact with 35A, the periphery of the opening 42 cannot be further expanded in the pulling direction. That is, the deformation of the opening 42 in the pulling direction is prevented by the engagement of the unevenness 29A and the unevenness 35A of the peripheral edge portion 43.

  FIG. 11 is a diagram showing a seventh modified example of the clothes fan 1. The garment fan 1 may include rubbers 29B and 35B (which are examples of the “engagement portion” in the present application) having a friction coefficient higher than that of resin, instead of the protrusions 29 and 35 described above. Both the rubber 29B and the rubber 35B may be provided in the clothes fan 1, or only one of them may be provided. Even if the materials having a relatively high friction coefficient such as the rubber 29B and the rubber 35B are applied to the cloth 41 of the garment 4 in the pulling direction due to the change in the posture of the wearer of the clothes fan 1, The movement of the peripheral portion 43 is blocked by the frictional force of the rubber 35B, and the periphery of the opening 42 cannot spread in the pulling direction. That is, the engagement of the peripheral edge portion 43 with the rubber 29B and the rubber 35B prevents the opening portion 42 from being deformed in the pulling direction.

  Further, in the above-described embodiment, the projections 29 and 35, the projections and depressions 29A and 35A, and the rubbers 29B and 35B, which correspond to the “locking portion” in the present application, are discretely arranged, but these are arranged in the flange portion 27 and the fixing member 3. It may be formed in an annular shape along the outer peripheral edge.
