However, since the two parts are connected using a rubber belt, the work of attaching them to clothes is complicated.

Japanese Patent No. 4399765

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a clothing fan that can be easily attached to and removed from clothing, and clothing with a fan.

The present invention has been made to solve the above-mentioned problems, and the clothes fan according to the present invention is a clothes fan that is attached to an attachment hole of clothes to ventilate the front side and the back side of the clothes, The main body includes a main body housing a motor fan, and a retaining ring detachably attached to the main body. The retaining ring is mounted on the outer peripheral surface of the peripheral wall of the main body housing from the other end side and is rotated in one direction around the axis. In this way, clothing is sandwiched between the flange portion of the main body and the flange portion of the main body. Characterized by The rear surface of the main body flange portion is the surface opposite to the holding surface for holding the clothes together with the retaining ring.

When attaching the clothing fan having this configuration to clothing, for example, the peripheral wall portion of the main body housing is inserted into the attachment hole from the front side of the clothing. The peripheral wall portion of the body housing protrudes to the back side of the garment through the attachment hole, while the body flange portion is positioned on the front side of the garment without passing through the attachment hole and contacts the surface of the garment. Then, the retaining ring is attached from the back side of the clothes to the outer peripheral surface of the peripheral wall portion of the body housing projecting to the back side of the clothes. At this time, by rotating the retaining ring in one direction around the axis, it can be brought closer to the body flange portion. By rotating the holding ring in one direction in this way, the clothes are sandwiched between the body flange portion and the holding ring, and the clothes fan is attached to the clothes. Conversely, when removing the clothing fan from clothing, the retaining ring can be easily removed from the main body by rotating the retaining ring in the direction opposite to the direction in which it was attached. By rotating the retaining ring relative to the main body in this manner, the clothes fan can be attached and detached. At that time, for example, one hand holds the main body flange portion, and the other hand grips and rotates the retaining ring. The flange portion of the body is relatively thin, making it difficult to grasp and stop its rotation. can be fixed. Therefore, when the retaining ring is rotated, the main body does not rotate together with the retaining ring, and only the retaining ring can be reliably rotated to attach/detach the clothing fan to/from clothing with good workability. In addition, although a power supply connector is generally connected to the main body of such a clothing fan, only the retaining ring can be reliably rotated to firmly attach the clothing fan to the clothing, so it can be used for clothing. It is possible to prevent a phenomenon in which the power supply connector is pulled in an unintended direction due to the rotation of the fan relative to the clothes, and the power supply connector is damaged.

In particular, irregularities are formed on the outer peripheral surface and the rear surface of the main body flange portion, and it is preferable that the irregularities on the outer peripheral surface of the main body flange portion and the irregularities on the rear surface are continuous. In this way, when the unevenness is continuous from the outer peripheral surface of the main body flange to the rear surface, the protrusion becomes a corner at the boundary between the outer peripheral surface and the rear surface of the main body flange, and the fingertip is caught on the corner. easier. Therefore, the body flange portion can be fixed more firmly.

In addition, the retaining ring is provided with a ring flange portion for holding clothes together with the body flange portion. preferably larger than the diameter of the part. When unevenness is formed on the outer peripheral surface of the main body flange portion, the main body flange portion can be firmly gripped by gripping the concave portion of the outer peripheral surface of the main body flange portion with the fingertips. At that time, the fingertip gripping the concave portion on the outer peripheral surface of the main body flange may protrude from the outer peripheral surface of the main body flange to the front side, ie, the holding ring side, through clothing. In such a case, if the ring flange portion facing the front side of the body flange portion has a small diameter, it is difficult for the fingertips to contact the outer peripheral surface of the ring flange portion through the clothing material, and the retaining ring can be rotated smoothly. can be done.

Further, a fan-equipped garment according to the present invention includes a garment and the above-described garment fan.

As described above, it can be attached to and detached from clothes by a simple operation of rotating the retaining ring. In addition, since the outer peripheral surface and the rear surface of the main body flange portion are formed with projections and depressions on which fingers can be caught, the device can be put on and taken off with good workability. It can also be attached securely to clothing.

In this manner, the holding surface 43a of the retaining ring 14 and the holding surface 19a of the main body 13 face each other in parallel to hold the garment 100 therebetween. As described above, the pressing projections 23 are formed on the holding surface 19a of the main body 13. Therefore, instead of holding the clothes 100 evenly along the entire periphery of the opening edge, the holding surface 19a of the main body 13 The pressing projection 23 of 19a and the holding surface 43a of the retaining ring 14 strongly pinch the garment 100 locally. When the garment 100 is not sandwiched, the holding surface 43a of the retaining ring 14 abuts against the pressing protrusion 23. As shown in FIG. When the nipping surface 43a of the retaining ring 14 is in contact with the pressing projection 23, there is a gap between the nipping surface 43a of the retaining ring 14 and the portion of the nipping surface 19a of the main body 13 where the pressing projection 23 is not formed. , a gap corresponding to the height of the pressing projection 23 is formed.

The outer peripheral surface of the retaining ring 14 is provided with irregularities that prevent slippage when the retaining ring 14 is rotated. Although the uneven shape is arbitrary, in this embodiment, the convex portions 44 and the concave portions 45 are alternately formed in the circumferential direction. The convex portions 44 and the concave portions 45 are alternately formed over the entire circumference. The thickness of the retaining ring 14 is relatively thick at the convex portion 44 , and the thickness of the retaining ring 14 is relatively thin at the concave portion 45 .

The clothing fan 1 configured as described above is attached to the attachment hole 101 of the clothing 100 in the following manner, for example. That is, the peripheral wall portion 18 of the main body 13 is inserted into the attachment hole 101 from the front side of the garment 100 . The peripheral wall portion 18 protrudes to the back side of the garment 100 through the attachment hole 101, while the main body flange portion 19 cannot pass through the attachment hole 101 and contacts the surface of the opening edge of the attachment hole 101 of the garment 100. . A retaining ring 14 is screwed onto the peripheral wall portion 18 of the main body 13 protruding to the back side of the garment 100 . By tightly tightening the retaining ring 14 clockwise, the opening edge of the attachment hole 101 of the garment 100 is clamped between the ring flange portion 43 and the body flange portion 19 . The clothing fan 1 can be attached to the clothing 100 by screwing the retaining ring 14 to the main body 13 in this manner. Conversely, when removing the clothing fan 1 from the clothing 100 , the retaining ring 14 is rotated counterclockwise to remove the retaining ring 14 from the main body 13 , thereby releasing the clothing 100 from the sandwiched state. is removed from the attachment hole 101 of the garment 100 to the front side.

Since the clothes 100 can be sandwiched between the main body 13 and the retaining ring 14 by a simple operation of rotating the retaining ring 14, the clothes fan 1 can be easily attached to the clothes 100. Removal from 100 is also easy. Further, since the holding ring 14 is rotated to sandwich the garment 100 together with the main body 13, a conventional rubber belt is not required and durability is excellent.

When attaching or detaching the clothing fan 1 to or from the clothing 100 by rotating the retaining ring 14 in this way, since the outer peripheral surface 19c and the back surface 19b of the main body flange portion 19 are formed with unevenness, respectively, it is possible to The main body 13 can be firmly fixed by hooking the hand on the unevenness of the body. Therefore, when the retaining ring 14 is rotated, the main body 13 and the retaining ring 14 do not rotate together, and it is possible to securely rotate only the retaining ring 14 to strongly tighten it or loosen the retaining ring 14 conversely. can. For example, the body flange portion 19 may be fixed by hooking fingers on the unevenness of the outer peripheral surface 19c of the body flange portion 19, or the body flange portion 19 may be pressed against the rear surface 19b of the body flange portion 19 with fingers or palms. The body flange portion 19 can be fixed by hooking a hand on the unevenness. Alternatively, the body flange portion 19 can be fixed by hooking a hand on both the unevenness of the outer peripheral surface 19c and the unevenness of the rear surface 19b. In particular, when the clothing material of the clothing 100 is thick, it is difficult to get the fingertips over the outer peripheral surface 19c of the main body flange portion 19 to the holding surface 19a through the clothing 100. Even if there is, since the rear surface 19b of the main body flange portion 19 is formed with unevenness, the rotation of the main body 13 can be prevented by hooking a hand on the unevenness of the rear surface 19b. The same applies to the case where a reinforcing material is attached to the opening edge of the attachment hole 101 of the garment 100, and the unevenness of the back surface 19b of the body flange 19 is used to easily prevent the body flange 19 from rotating. can do.

Furthermore, the unevenness continuously extends from the outer peripheral surface 19c of the main body flange portion 19 to the back surface 19b, and the boundary portion between the outer peripheral convex portion 70 and the rear convex portion 72 forms a protruding corner. Therefore, the fingertip can be easily hooked on the corner, and the main body 13 can be fixed more firmly.

Further, even if the fingertip gripping the outer peripheral recess 71 of the main body flange 19 exceeds the outer peripheral surface 19c of the main body flange 19 toward the holding surface 19a and protrudes toward the retaining ring 14, the outer peripheral recess of the main body flange 19 is prevented. Since the diameter at 71 is larger than the diameter of the ring flange portion 43, the fingertips are less likely to come into contact with the outer peripheral surface of the ring flange portion 43 through the clothing material. That is, gripping the body flange portion 19 and the ring flange portion 43 together with the fingertips through the clothing material is suppressed. Therefore, only the retaining ring 14 can be smoothly rotated.

In addition, although the male connector 4 is connected to the body 13, the clothing fan 1 can be firmly attached to the clothing 100 by the unevenness of the body flange portion 19, so that the attached clothing fan 1 can be attached to the clothing 100. It does not rotate. Therefore, it is difficult to apply a load to the male connector 4, and damage thereof can be prevented.

Further, since the pressing projections 23 are formed on the holding surface 19a of the main body flange portion 19 of the main body 13, the pressing projections 23 can be strongly pressed against the clothes 100, and the clothes fan 1 can be securely attached to the clothes 100. be able to. Further, since the retaining ring 14 is provided with the ring flange portion 43, the radial dimension (width) of the holding surface 43a of the retaining ring 14 can be increased, and a stable mounting state can be obtained.

Further, when the lower portion 18b of the peripheral wall portion 18 of the main body 13 is inserted into or removed from the attachment hole 101 of the garment 100, the male screw portion 21 slides on the opening edge of the attachment hole 101 of the garment 100. However, since the tip of the screw thread of the male screw part 21 is rounded, the male screw part 21 is less likely to get caught on the clothes 100, and the main body 13 can be smoothly inserted into and removed from the mounting hole 101. .

In this embodiment, both the outer peripheral surface 19c and the rear surface 19b of the main body flange portion 19 are formed with irregularities, but only one of them may be formed with irregularities. For example, as shown in FIG. 12, the outer peripheral surface 19c of the main body flange portion 19 is formed with the outer peripheral convex portion 70 and the outer peripheral recessed portion 71, while the rear surface 19b of the main body flange portion 19 does not have to be uneven.

Further, in the above-described embodiment, the retaining ring 14 is screwed to the peripheral wall portion 18 of the main body housing 15, but the retaining ring 14 is rotated and attached to the peripheral wall portion 18 of the main body housing 15 by a configuration other than screws. You may do so. For example, FIGS. 13 to 16 show configurations using engagement grooves 50 instead of screws. As shown in FIG. 15, an engaging groove 50 is formed in the outer peripheral surface of the lower portion 18b of the peripheral wall portion 18 of the main body housing 15. As shown in FIG. The engaging groove 50 is composed of an inclined groove 51 extending obliquely downward, and a vertical groove 52 extending vertically (axially) from the upper end of the inclined groove 51 to the upper end of the lower portion 18b of the peripheral wall portion 18 . . The inclination angle of the inclined grooves 51 with respect to the circumferential direction is preferably less than 45 degrees. The lower end portion of the inclined groove 51 is located in the middle of the outer peripheral surface of the lower portion 18 b of the peripheral wall portion 18 in the vertical direction and is located above the body flange portion 19 . A pair of such engagement grooves 50 are formed on the outer peripheral surface of the lower portion 18b of the peripheral wall portion 18 of the body housing 15 so as to face each other 180 degrees. However, the number and arrangement of the engagement grooves 50 are arbitrary.

On the other hand, an engaging projection 60 that engages with the engaging groove 50 of the main body 13 is formed on the inner peripheral surface of the retaining ring 14 . The engaging projections 60 are formed corresponding to the number and arrangement of the engaging grooves 50 of the main body 13. In this embodiment, the engaging projections 60 project radially inward at two positions facing each other 180 degrees. there is Although the shape of the engaging projection 60 is arbitrary, it may be cylindrical, for example. A ridge 61 is formed on the outer peripheral surface of the retaining ring 14 at a position corresponding to the engaging projection 60, and the ridge 61 serves as a mark. The position of the mating projection 60 can be grasped.

When attaching the retaining ring 14 to the main body 13 as shown in FIGS. 13 and 14, the engaging protrusions 60 of the retaining ring 14 are positioned above the vertical grooves 52 of the engaging grooves 50, and the retaining ring 14 is lowered therefrom. to engage the engaging protrusion 60 with the longitudinal groove 52 . By rotating the retaining ring 14 clockwise in a front view, the engaging projection 60 moves toward the lower end portion of the inclined groove 51 . As the engaging projection 60 is guided by the inclined groove 51 of the engaging groove 50 in this way, the retaining ring 14 gradually descends along the inclined groove 51 and approaches the body flange portion 19 . Therefore, the garment 100 can be sandwiched between the ring flange portion 43 and the body flange portion 19 .

Even in the case of such a structure with the engagement groove 50, the outer peripheral surface 19c and the rear surface 19b of the main body flange portion 19 may be uneven. For example, as shown in FIGS. 13 and 14, an outer peripheral convex portion 70 and an outer peripheral concave portion 71 may be formed on the outer peripheral surface 19c of the body flange portion 19. FIG.

Further, it is preferable to provide the main body 13 and the retaining ring 14 with a locking mechanism. Specifically, a locking groove 53 extending in the vertical direction is formed in the outer peripheral surface of the lower portion 18b of the peripheral wall portion 18 of the body housing 15 . The locking groove 53 is formed over the entire length in the vertical direction from the upper end to the lower end of the outer peripheral surface of the lower portion 18b of the peripheral wall portion 18 . Although one locking groove 53 may be provided, in this embodiment, a large number of locking grooves 53 are arranged in parallel at equal intervals in the circumferential direction. A pair of groups of locking grooves 53, which form one set of a large number of grooves, are provided so as to face each other 180 degrees.

On the other hand, the retaining ring 14 has a flexible piece 62 at one point on its circumference. Slits 63 are formed on both left and right sides (both sides in the circumferential direction) of the flexible piece 62 . The slit 63 extends from the upper end of the retaining ring 14 to near the lower end of the retaining ring 14 . Therefore, the flexible piece 62 is connected to the rest of the retaining ring 14 only at its lower end, and elastically deforms radially inward and outward with the lower end as a fulcrum. A locking projection 64 is formed on the inner surface of the flexible piece 62 to lock into the locking groove 53 of the main body 13 . The locking projection 64 extends in the vertical direction, that is, along the axial direction of the retaining ring 14 . The vertical length of the locking projection 64 is shorter than that of the locking groove 53 . A locking projection 64 is formed on the upper portion of the flexible piece 62 .

As described above, when the retaining ring 14 is rotated and attached to the main body 13 , the retaining projections 64 of the retaining ring 14 are sequentially retained in the retaining grooves 53 of the main body 13 . When attaching the retaining ring 14 to the main body 13, the retaining ridge 64 of the retaining ring 14 is first retained in the rightmost retaining groove 53 as viewed from the side. When the retaining ring 14 is further rotated clockwise from that position, the flexible piece 62 is elastically deformed radially outward, overcoming the ridges between the locking grooves 53 and closing the adjacent locking groove on the left. Lock again at 53. That is, the locking projection 64 is sequentially locked from the right locking groove 53 to the left locking groove 53 like a latch. 14, when the engaging projection 60 of the retaining ring 14 reaches the vicinity of the lower end of the engaging groove 50 of the main body 13, it is the leftmost of the group of locking grooves 53 seen from the side. The locking projection 64 is locked in the locking groove 53 located.

By engaging the retaining projection 64 of the retaining ring 14 in the retaining groove 53 of the main body 13 in this manner, the retaining ring 14 can be retained at that position, and loosening of the retaining ring 14 can be prevented. . In addition, since a large number of locking grooves 53 are arranged in parallel, the retaining ring 14 is locked at any locking groove 53 in which the locking projection 64 is locked. Therefore, even if the thickness of the garment 100 increases or decreases, it can be easily accommodated. In the case where the thickness is large, the locking projection 64 may be locked in the locking groove 53 on the right side.

The flexible piece 62 preferably protrudes above the upper end of the retaining ring 14 by a predetermined length. By pressing the upward projecting portion 65 of the flexible piece 62 projecting upward from the upper end of the retaining ring 14 radially outward with a finger, the flexible piece 62 is forcibly elastically deformed radially outward to form the locking projection. 64 can be removed from the locking groove 53 . Then, in this state, the retaining ring 14 can be removed from the main body 13 by rotating the retaining ring 14 in the direction opposite to that at the time of attachment.

It should be noted that when the rotational operating force that attempts to rotate the retaining ring 14 in the direction opposite to that at the time of attachment exceeds a predetermined value, the reaction force received by the locking projection 64 from the locking groove 53 causes the flexible piece 62 to move radially. It may be configured so that the locking projection 64 is elastically deformed outward in the direction to climb over the locking groove 53 . With this configuration, when removing the retaining ring 14 from the main body 13, it is not necessary to press the above-described upward projecting portion 65 radially outward with a finger, which is convenient.

Alternatively, only one locking groove 53 may be formed. Alternatively, the main body 13 may be formed with the engaging protrusions 60 and the retaining ring 14 may be formed with the engaging grooves 50 . Similarly, the main body 13 may be formed with the locking ridges 64 and the retaining ring 14 may be formed with the locking grooves 53 .

Further, although the ring flange portion 43 is provided on the retaining ring 14, the ring flange portion 43 may not be provided. However, by providing the ring flange portion 43, the width of the holding surface 43a of the retaining ring 14 can be increased.
