Further, a ring-shaped member is fitted into the fan main body portion in the axial direction of the fan from the inside of the clothes, and the locking portion of the fan main body portion is engaged with the protrusion of the ring-shaped member. Thereby, the air blower is fixed to the clothes in a state where the fabric is sandwiched from the outside and the inside by the flange portion and the ring-shaped member.

International Publication No. 2007/061088

  In the blower, the gap between the flange portion and the ring-shaped member when the locking portion and the protrusion are engaged is constant. For this reason, depending on the thickness of the clothes on which the blower is mounted, the blower may not be securely fixed to the clothes. On the other hand, since the thickness of the garment worn by the worker is often different depending on the season and the working environment, a blower capable of handling a plurality of types of garments having different thicknesses is desired.

  This invention makes it a subject to provide the technique regarding the air blower which can respond to multiple types of clothing which has different thickness.

  According to one aspect of the present invention, a blower configured to be detachable from clothes is provided. The blower device includes a motor, a fan, a housing, a mounting member, a first clamping unit, a second clamping unit, and a locking mechanism.

  The housing accommodates a motor and a fan that is rotationally driven by the motor. The mounting member is configured to be detachably mounted to the housing along a predetermined operation line. The first clamping part is provided on the housing, while the second clamping part is provided on the mounting member. The second clamping unit is configured to be opposed to the first clamping unit in the direction of the rotation axis of the fan when the mounting member is mounted on the housing, and to sandwich the clothes clothes with the first clamping unit. ing.

  The locking mechanism is configured to restrict movement of the mounting member in the rotation axis direction relative to the housing by locking the mounting member with respect to the housing in the rotation axis direction of the fan. The locking mechanism includes a first locking portion provided on one of the housing and the mounting member, and a second locking portion provided on the other of the housing and the mounting member. The second locking portion is configured to lock the first locking portion in the rotation axis direction at any one of a plurality of locking positions different from each other in the rotation axis direction of the fan. Each of the plurality of locking positions is on a path through which the first locking portion can pass in the process in which the mounting member is mounted on the housing along the operation line.

  Here, “a plurality of locking positions different from each other in the direction of the rotation axis” means a case where the positions are different from each other on the same straight line extending in the direction of the rotation axis, and also intersects the rotation axis in the direction of the rotation axis. It may include a case where the position is different in the direction. Further, “locking in the direction of the rotating shaft” includes a case of locking in only one predetermined direction of the extending direction of the rotating shaft and a case of locking in both directions of the extending direction of the rotating shaft. sell. It is preferable that at least the mounting member and the housing are locked in a direction away from each other.

  According to this aspect, the second locking portion has a plurality of engagements in the direction of the rotation axis of the fan, that is, in the opposing direction of the first clamping portion and the second clamping portion that clamp the clothing. It can be locked at any one of the stop positions. Therefore, the user selects the locking position of the first locking portion with respect to the second locking portion according to the thickness of the clothes to be worn, so that the user can appropriately use the first clamping portion and the second clamping portion. You can pinch clothes. Further, the plurality of locking positions are on a predetermined path through which the first locking portion can pass in the process in which the user mounts the mounting member on the housing along a predetermined operation line. Therefore, the user may lock the first locking portion to the second locking portion at an appropriate locking position in a series of operations for mounting the mounting member on the housing. That is, it is not necessary to remove the mounting member from the housing and mount it again in order to change the locking position. Thus, the air blower of this aspect can cope with a plurality of types of clothes having different thicknesses with an easy operation.

The additional locking mechanism restricts at least one of movement of the mounting member relative to the housing in the rotation axis direction and rotation in the circumferential direction by locking the mounting member relative to the housing in at least one of the rotation axis direction and the circumferential direction. It may be configured to. According to this aspect, since the additional locking mechanism is used in combination with the locking mechanism (and the rotation regulating mechanism), even if the combined mechanism does not function for some reason, the additional locking mechanism performs its function. Therefore, it is possible to more reliably prevent the mounting member from being detached from the housing.

  According to one aspect of the present invention, at least one of the housing and the mounting member may have a finger hooking projection or recess. In this case, when the user attaches / detaches the mounting member to / from the housing, the attaching / detaching operation can be easily performed.

  According to one aspect of the invention, the color of the mounting member may be different from the color of the housing. According to this aspect, since the user can visually distinguish the housing and the mounting member attached to and detached from the housing, the attaching / detaching operation (particularly, the removing operation) becomes easier. Note that the mounting member and the housing may each be formed entirely in one color, or may include different colors in part. When the color of a part of the mounting member and the part of the housing are different from each other, it is preferable that the color of the part visible from the same direction is different when the blower is mounted on clothes. Further, the color of the mounting member is preferably a color having a clear contrast with the color of the housing.

  According to one aspect of the present invention, a blower configured to be detachable from clothes is provided. The blower device includes a motor, a fan, a housing, a mounting member, a first clamping unit, a second clamping unit, and a locking mechanism.

In the present embodiment, the opening formed between the first rib 463, the second rib 464, and the third rib 465 of the exhaust part 46 constitutes the exhaust port 467. Each exhaust port 467 penetrates in the direction of the rotation axis A1, and when the fan 36 is rotated, the air flowing into the housing 4 from the intake port 457 flows out from the rear toward the front through the exhaust port 467. To do. Of the exhaust ports 467, the exhaust ports 467 formed between the third ribs 465 also penetrate in the direction intersecting the rotation axis A1. Therefore, the air that has flowed into the housing 4 from the air intake port 457 flows out through the exhaust port 467 also in the direction intersecting the rotation axis A1.

  As shown in FIG. 3, a region where the first rib 463 to the third rib 465 are not provided is provided in a part of the exhaust portion 46 in the circumferential direction. This area constitutes a connector arrangement area 38 in which the connector (plug) 973 (see FIG. 9) of the cable 97 is arranged. A connector (jack) 37 that is electrically connected to the motor 33 is disposed on the rotation axis A1 side with respect to the connector arrangement region 38. The connector 37 is arranged so that the connector 973 of the cable 97 is inserted and removed in a direction orthogonal to the rotation axis A1 (in the radial direction of the main body 3).

  Further, the housing 4 is provided with a regulating rib 381 configured to restrict the connector 973 from moving outward in the radial direction (in other words, the direction in which the connector 973 is detached from the connector 37). The restricting rib 381 is a rib (wall portion) that is provided on the outer side in the radial direction with respect to the connector arrangement region 38 and is configured to come into contact with the connector 973 arranged in the connector arrangement region 38. The regulation rib 381 can prevent the connector 973 from coming off the connector 37 by coming into contact with the connector 973 from the outside in the radial direction. Thereby, when a user moves during the operation | work which wears the jacket 9 to which the air blower 1 was attached, when the cable 97 is moved, the cable 97 may remove | deviate from the air blower 1. Can be reduced. The state in which the connector 973 is connected to the connector 37 is shown in FIG. 16 and FIG. 17 corresponding to a modification described later.

  Hereinafter, the ring member 5 will be described with reference to FIGS. 3 and 4. As shown in FIG. 4, the ring member 5 includes an outer cylindrical portion 51, the above-described front flange 53, and a finger hooking protrusion 55. In the present embodiment, the outer cylindrical portion 51, the front flange 53, and the finger hooking projection 55 are integrally formed of resin. In the present embodiment, the ring member 5 is formed of a resin having a color different from that of the housing 4. Specifically, a color having a clear contrast is employed, and the ring member 5 is formed generally in green, while the housing 4 is formed generally in white.

  The outer cylinder part 51 is a part that is fitted on the inner cylinder part 41 of the housing 4. Therefore, the outer cylindrical portion 51 is formed as a short cylindrical body having an inner diameter substantially the same as the outer diameter of the inner cylindrical portion 41 of the housing 4.

  As described above, the front flange 53 opposes the rear flange 43 of the housing 4 in the front-rear direction (rotational axis A1 direction), and between the rear flange 43, the fan attachment portion 93 of the attachment opening 91 of the outer jacket 9. It is a part which clamps. The front flange 53 is provided so as to protrude radially outward from one end portion (specifically, the rear end portion) of the outer cylinder portion 51 in the direction of the central axis A2. In the present embodiment, the outer diameter of the front flange 53 is set to be substantially the same as the outer diameter of the rear flange 43 of the housing 4.

  The finger hooking protrusion 55 is a protrusion for facilitating the user to hold the ring member 5 by hooking his / her finger, to rotate around the central axis A2, or to hold it so as not to rotate. In the present embodiment, the finger hooking projection 55 is formed in a substantially triangular plate shape, and its two sides are connected to the outer peripheral surface of the outer cylindrical portion 51 and the front surface of the rear flange 53, and the plate surface is the circumferential direction of the central axis A2. It is provided to cross. In the present embodiment, a plurality of finger hooking projections 55 are provided, and are arranged apart from each other in the circumferential direction.

  As shown in FIG. 4, the air blower 1 configured as described above further includes a locking mechanism 6, a rotation restricting mechanism 7, and an additional locking mechanism 8. The locking mechanism 6 locks the ring member 5 with respect to the housing 4 in the direction of the rotation axis A1 (direction of the central axis A2), thereby restricting movement of the ring member 5 with respect to the housing 4 in the direction of the rotation axis A1. It is a structured mechanism. The rotation restricting mechanism 7 is a mechanism configured to restrict the rotation of the ring member 5 relative to the housing 4 by locking the ring member 5 in the circumferential direction around the rotation axis A <b> 1 with respect to the housing 4. In addition to the locking mechanism 6 and the rotation restricting mechanism 7, the additional locking mechanism 8 is a mechanism configured to restrict the movement of the ring member 5 relative to the housing 4 in the direction of the rotation axis A1 and the rotation around the rotation axis A1. It is. Hereinafter, the configuration of these mechanisms will be described in order.

  First, the configuration of the locking mechanism 6 will be described with reference to FIGS. 4 to 7 and FIG. In the present embodiment, the locking mechanism 6 includes a guide groove 61 provided in the inner cylindrical portion 41 of the housing 4 and a locking projection 66 provided in the outer cylindrical portion 51 of the ring member 5.

  As shown in FIGS. 4 and 5, the guide groove 61 is a groove formed so as to be recessed radially inward from the outer peripheral surface of the inner cylindrical portion 41. The guide groove 61 is formed in a substantially L shape as a whole, and includes a first portion 611 and a second portion 614. The first portion 611 is a portion of the guide groove 61 that extends in the direction of the rotation axis A <b> 1 from the front end of the inner cylinder portion 41 (on the exhaust portion 46 side in the direction of the rotation axis A <b> 1) to the rear flange 43. The second portion 614 is a portion of the guide groove 61 that continuously extends from the rear portion of the first portion 611 in the circumferential direction (specifically, in the clockwise direction D1). In the present embodiment, the guide groove 61 is a groove that defines a path through which a locking protrusion 66 (see FIG. 4) of the ring member 5 described later can pass in the process in which the ring member 5 is attached to and detached from the housing 4. It is configured. Specifically, in the process in which the ring member 5 is attached to and detached from the housing 4, the locking protrusion 66 is inserted into the guide groove 61 and guided along the guide groove 61.

  The front end of the first portion 611 constitutes a receiving port 612 that receives the locking protrusion 66 of the ring member 5 into the guide groove 61. A wall surface defining the front end of the second portion 614 (that is, a surface portion extending radially inward from the outer peripheral surface of the inner cylindrical portion 41 to the bottom of the groove) extends in the circumferential direction (specifically, in the clockwise direction D1). However, it is slightly inclined backward toward the rear flange 43. This wall surface is referred to as a guide surface 615.

  A first locking portion 616 that is a surface substantially orthogonal to the rotation axis A <b> 1 is formed at an intermediate portion in the circumferential direction of the guide surface 615. In the clockwise direction D1, a slight rearward step 618 (rightward in FIG. 5) is provided at the downstream end (lower end in FIG. 5) of the first locking portion 616. The guide surface 615 extends from the step 618 while being slightly inclined toward the downstream side.

  A second locking portion 617 that is a surface substantially orthogonal to the rotation axis A <b> 1 is formed at the terminal end portion of the guide surface 615 (that is, the end portion farthest from the first portion 611). In other words, the second locking portion 617 is disposed downstream of the first locking portion 616 in the clockwise direction D1. Further, the second locking portion 617 is located at a different position from the first locking portion 616 in the direction of the rotation axis A1 (that is, the facing direction of the front flange 53 and the rear flange 43, the front-rear direction). More specifically, the second locking portion 617 is located closer to the rear flange 43 than the first locking portion 616 (more rearward) in the direction of the rotation axis A1. That is, the distance between the second locking portion 617 and the rear flange 43 in the direction of the rotation axis A <b> 1 is shorter than the distance between the first locking portion 616 and the rear flange 43.

  As shown in FIG. 4, the locking protrusion 66 is provided so as to protrude radially inward from the inner peripheral surface of the outer cylindrical portion 51 of the ring member 5. In the present embodiment, the locking projection 66 is integrally formed with the outer cylinder portion 51 at the rear end of the outer cylinder portion 51 as a rectangular parallelepiped projection. As described above, since the locking projection 66 is guided in the guide groove 61, the locking projection 66 is set to a size that can be inserted into the guide groove 61.

  As shown in FIG. 7, in the present embodiment, three guide grooves 61 are provided at three equal intervals in the circumferential direction of the inner cylindrical portion 41. In addition, as shown in FIG. 12, three locking projections 66 are provided at three equal intervals in the circumferential direction of the outer cylindrical portion 51.

  Further, as shown in FIG. 4, the housing 4 includes a first position mark 621 and a second position at positions corresponding to the first locking portion 616 and the second locking portion 617 of the three guide grooves 61. A two-position mark 627 is attached. The first position mark 621 and the second position mark 627 are provided on the front end surface of the inner cylinder portion 41 that is a portion that is not hidden even when the ring member 5 is fitted on the inner cylinder portion 41. In the present embodiment, each of the first position mark 621 and the second position mark 627 is configured as an equilateral triangle mark in which one vertex is directed radially outward. The first position mark 621 and the second position mark 627 can easily recognize the positions of the first locking portion 616 and the second locking portion 617 from the front even when the ring member 5 is externally fitted to the inner cylindrical portion 41. It is a landmark to make it possible.

  On the other hand, the ring member 5 is provided with a reference projection mark 63 at a position corresponding to one of the three locking projections 66. The reference protrusion mark 63 is provided on the flange-shaped front end surface of the outer cylindrical portion 51 which is a portion that is not hidden even when the ring member 5 is fitted on the inner cylindrical portion 41. In the present embodiment, the reference protrusion mark 63 is configured as an equilateral triangle mark in which one of the apexes is directed radially inward. Even when the ring member 5 is externally fitted to the inner cylindrical portion 41, the reference projection mark 63 is formed from the front (that is, from the direction in which the first position mark 621 and the second position mark 627 can be visually recognized). It is a mark that makes it easy to recognize the position.

  The reference protrusion mark 63 functions as a mark for alignment of the ring member 5 with respect to the housing 4 in cooperation with the first position mark 621 and the second position mark 627 described above. The first position mark 621 and the second position mark 627 are provided corresponding to only one of the three guide grooves 61, and only one of the locking protrusions 66 having the three reference protrusion marks 63 is provided. The additional locking mechanism 8 to be described later is provided only at one location in the circumferential direction. The alignment of the ring member 5 with respect to the housing 4 will be described in detail later.

  Next, the configuration of the rotation restricting mechanism 7 will be described with reference to FIGS. 4, 7, and 12. In the present embodiment, the rotation restricting mechanism 7 includes a rotation locking part 71 provided in the inner cylinder part 41 of the housing 4 and a locking piece 75 provided in the outer cylinder part 51 of the ring member 5.

  In the present embodiment, the rotation locking portion 71 includes a first recess 711 and a second recess 716. Each of the first recess 711 and the second recess 716 is a recess formed so as to be recessed inward in the radial direction from the outer peripheral surface of the inner cylindrical portion 41 so as to lock a locking piece 75 described later in the circumferential direction. It is configured.

  As shown in FIG. 4, the first recess 711 is provided as a recess extending from the rear flange 53 forward to the vicinity of the front end of the inner cylindrical portion 41. Further, as shown in FIG. 7, the first recess 711 has a V-shaped cross section orthogonal to the rotation axis A1. Of the two surfaces defining the first recess 711, the upstream surface 712 extends in the radial direction in the clockwise direction D <b> 1, while the downstream surface 713 is the outer peripheral surface of the surface 712 and the inner cylinder portion 41. Connect with a gentle inclination. The surface 712 functions as an engagement surface that engages with a claw 751 of a locking piece 75 described later. Further, the surface 713 functions as a guide surface that guides the removal of the claw 751 disposed in the first recess 711 in the clockwise direction D1.

  As shown in FIG. 4, the second concave portion 716 is formed as a concave portion having a rectangular shape in a side view at the downstream side of the first concave portion 711 in the clockwise direction D1 and at the substantially central portion of the inner cylindrical portion 41 in the rotation axis A1 direction. Is provided. Further, as shown in FIG. 7, the second recess 716 has a rectangular cross section orthogonal to the rotation axis A1. Of the three surfaces defining the second recess 716, the most upstream surface 717 in the clockwise direction extends substantially in the radial direction and functions as an engagement surface that engages with the claw 751 of the locking piece 75. Furthermore, as shown in FIG. 5, the front end of the second recess 716 is located farther from the front end of the inner cylindrical portion 41 than the front end of the first recess 711.

  In the direction of the rotation axis A1 (front-rear direction), the distance between the front end of the first recess 711 and the front end of the second recess 716 is between the first locking portion 616 and the second locking portion 617 of the guide groove 61. Corresponds to the distance. In the clockwise direction D1, the distance between the upstream end of the first recess 711 and the upstream end of the second recess 716 is equal to the downstream end of the first locking portion 616 of the guide groove 61. This corresponds to the distance between the downstream ends of the two locking portions 617.

  As shown in FIGS. 4 and 5, a guide recess 73 is provided at the front end of the inner cylinder portion 41 on the upstream side of the first recess 711 in the clockwise direction D <b> 1. The guide recess 73 is a recess that is shallower than the first recess 711 and the second recess 716, and is entirely defined by a curved surface so that the center of the front end is deepest. The guide recess 73 receives a locking piece 75 (specifically, a claw 751), which will be described later, and guides it to the outer peripheral surface of the inner cylindrical portion 41.

  In the present embodiment, a guide recess 73, a first recess 711, and a second recess 716 are arranged in order from the upstream side in the clockwise direction D1. Further, the guide concave portion 73, the first concave portion 711, and the second concave portion 716 are set as one set, and three sets of the guide concave portion 73, the first concave portion 711, and the second concave portion 716 are respectively disposed between the above three guide grooves 61. Has been placed.

  As shown in FIG. 4, the locking piece 75 is formed integrally with the outer cylindrical portion 51 so as to extend in the circumferential direction of the outer cylindrical portion 51 of the ring member 5 as a flexible band-shaped member. ing. The locking piece 75 has an upstream end in the clockwise direction D <b> 1 connected to the outer cylinder 51, and can bend in the radial direction with respect to the outer cylinder 51. As shown in FIG. 12, a claw 751 protruding radially inward is provided on the inner surface (surface on the central axis A2 side) of the downstream end portion (tip portion) in the clockwise direction D1 of the locking piece 75. Yes. The locking piece 75 is configured to be able to be locked to the first recess 711 and the second recess 716 described above via the claw 751. Further, a tab 756 that protrudes outward in the radial direction is provided at the distal end portion of the locking piece 75. The tab 756 is configured so that the user can perform a pressing operation with a finger in the counterclockwise direction D2 or a pinch operation with a finger, and the first recess 711 (surface 712) of the nail 751. Alternatively, it is used to release the engagement with the second recess 716 (surface 717).

  In the circumferential direction, the distance between the locking protrusion 66 corresponding to the reference protrusion mark 63 and the claw 751 of the locking piece 75 is a guide corresponding to the first position mark 621 and the second position mark 627. This corresponds to the distance between the receiving port 612 of the groove 61 and the guide recess 73 closest to the upstream side of the guide groove 61 in the clockwise direction D1.

  Hereinafter, the configuration of the additional locking mechanism 8 will be described with reference to FIGS. 4 and 10. In the present embodiment, the additional locking mechanism 8 includes a fastener 81 provided on the front side of the inner cylindrical portion 41 of the housing 4 and a fastener holding portion 83 provided on the outer cylindrical portion 51 of the ring member 5. .

  As shown in FIG. 10, the fastener 81 is configured as a metal member formed in a U shape. Both end portions of the fastener 81 are supported by a rectangular parallelepiped base 811 provided on the front end surface of the inner cylinder portion 41 (the outer peripheral portion of the exhaust portion 46). The fastener 81 is rotatable in the direction of the rotation axis A1 (front-rear direction) about a rotation axis extending in the circumferential direction. More specifically, the fastener 81 is rotatable between a release position shown in FIG. 4 and a fixed position shown in FIG. At the release position, the fastener 81 is disposed on the radially inner side of the outer diameter of the inner cylindrical portion 41 when viewed from the direction of the rotation axis A1. Therefore, when the fastener 81 is disposed at the release position, the ring member 5 can be attached to and detached from the outer peripheral portion of the inner cylindrical portion 41. On the other hand, in the fixed position, the fastener 81 is disposed so as to protrude outward in the radial direction from the outer diameter of the inner cylindrical portion 41 when viewed from the direction of the rotation axis A1.

  As shown in FIG. 4, the fastener holder 83 includes a first holder 831 arranged on the upstream side in the clockwise direction D1 and a second holder 836 arranged on the downstream side. In the clockwise direction D1, the distance between the upstream end of the first holding portion 831 and the upstream end of the second holding portion 836 is the downstream end of the first locking portion 616 of the guide groove 61. And the distance between the downstream end of the second locking portion 617.

  Each of the first holding portion 831 and the second holding portion 836 includes a pair of locking pieces. The pair of locking pieces are formed integrally with the outer cylindrical portion 51 and are provided so as to protrude forward from the front end of the outer cylindrical portion 51 while being spaced apart from each other in the circumferential direction. The pair of locking pieces have flexibility in the circumferential direction, and are provided with claws protruding in a direction away from each other at the front end portion (tip portion) so that the fastener 81 can be held. Specifically, the pair of locking pieces can be inserted into the fastener 81 when an external force is applied in a direction adjacent to each other in the circumferential direction. When the pair of locking pieces return to the initial position, the claw at the tip holds the fastener 81 in a non-detachable manner.

  The blower 1 having the above configuration is used by being attached to a jacket 9 (see FIGS. 1 and 2) by a user. The blower 1 can be attached to and detached from clothes having a fan mounting portion 93 (see FIG. 2) in addition to the jacket 9. The blower device 1 of the present embodiment can be adapted to clothes of various thicknesses by the above-described locking mechanism 6, rotation restriction mechanism 7, and additional locking mechanism 8.

  Hereinafter, with reference to FIGS. 2, 4, and 10 to 14, the operation of the blower device 1 (particularly, the locking mechanism 6, the rotation restricting mechanism 7, and the like) when attaching to and detaching from clothes (for example, the jacket 9). The action of the additional locking mechanism 8) will be described in detail.

  When the blower 1 is attached to the jacket 9, the user first attaches a part of the main body 3 with the ring member 5 removed as shown in FIG. 4 to the attachment opening 91 ( 2). Specifically, the rear flange 43 is disposed outside the back body (fan attachment portion 93), and the inner cylinder portion 41 and the exhaust portion 46 are inserted into the outer jacket 9 from the attachment opening 91. As a result, the fan mounting portion 93 (clothing) is disposed on the front surface of the rear flange 43.

  The blower device 1 of the present embodiment is configured such that the ring member 5 is attached to the housing 4 along a predetermined operation line. The “operation line” refers to a flow line or an operation line that is followed when the ring member 5 is attached to the housing 4. Alternatively, it can be paraphrased as the mounting direction when the ring member 5 is mounted on the housing 4. The operation line is typically expressed as a linear or curved operation in a predetermined direction, or a combination of a plurality of such operations.

  In the present embodiment, the ring member 5 is attached to the housing 4 along operation lines that are combined in the order of the rotation axis A1 and the circumferential direction around the rotation axis A1. That is, the ring member 5 is mounted on the housing 4 by being relatively moved with respect to the housing 4 in the direction of the rotation axis A1 and then being relatively moved in the circumferential direction. More specifically, the ring member 5 is relatively moved in the direction close to the housing 4 in the direction of the rotation axis A1 (in other words, the direction in which the front flange 52 approaches the rear flange 43), and then the clockwise direction D1. Is attached to the housing 4 by being relatively moved.

  In addition, the above-mentioned “in order of the rotation axis A1 direction and the circumferential direction” means that the movement of the ring member 5 relative to the housing 4 as a whole is allowed while allowing a certain degree of variation in the rotation axis direction and the circumferential direction. It means that the rotation is performed in the order of the rotation axis A1 and the circumferential direction. That is, the relative movement of the ring member 5 in the direction of the rotational axis A1 may be accompanied by a slight relative movement in the circumferential direction, and the relative movement of the ring member 5 in the circumferential direction may be performed slightly in the direction of the rotational axis A1. May be accompanied by relative movement. Further, the transition from the direction of the rotation axis A1 to the circumferential direction may be performed as a transition accompanied by an abrupt angle change, or may be performed as a moderately continuous transition.

  At the time of removal, the ring member 5 follows the operation line in the direction opposite to that at the time of mounting. That is, the ring member 5 is relatively moved in the circumferential direction with respect to the housing 4, and is then relatively moved in the direction of the rotation axis A1. More specifically, the ring member 5 is relatively moved in the counterclockwise direction D2, and is then relatively moved in the direction away from the housing 4 in the direction of the rotation axis A1 (in other words, the direction in which the front flange 52 is separated from the rear flange 43). It is removed from the housing 4 by being moved.

  As described above, since the inner diameter of the outer cylinder portion 51 is substantially the same as the outer diameter of the inner cylinder portion 41, the user aligns the locking projection 66 with any one of the three receiving ports 612. Unless this is done, the ring member 5 cannot be fitted into the outer peripheral portion of the inner cylindrical portion 41 of the housing 4. Therefore, the user first aligns the ring member 5 with respect to the housing 4 in the circumferential direction.

  Specifically, the user grasps the outer rear flange 43 of the outer garment 9 with one hand, grasps the ring member 5 with the other hand, and sets the reference projection mark 63 of the ring member 5 to In the clockwise direction D1, the position is aligned with the receiving port 612 that is closest to the upstream side of the first position mark 621 of the inner cylindrical portion 41. When the alignment is performed, the locking projection 66 corresponding to the reference projection mark 63 can enter the guide groove 61 from the receiving port 612 (see FIG. 5) in the direction of the rotation axis A1. The other two locking projections 66 can also enter the guide groove 61 via the other two receiving ports 612, respectively. Further, the claw 751 of the locking piece 75 can enter the guide recess 73. At this time, the fastener 81 of the additional locking mechanism 8 is placed in the release position.

  The user moves the ring member 5 backward with respect to the housing 4. When the locking projection 66 is guided along the first portion 611 of the guide groove 61, the ring member 5 is mounted and guided rearward in the direction of the rotation axis A <b> 1 with respect to the housing 4.

  When the locking projection 66 is moved rearward to the position of the second portion 614, the ring member 5 can move in the clockwise direction D1 with respect to the housing 4 in addition to the direction of the rotation axis A1. The user rotates the ring member 5 in the clockwise direction D <b> 1 with respect to the housing 4, and causes the locking protrusion 66 to enter the second portion 614. As the locking projection 66 enters the second portion 614 from the first portion 611, the claw 751 of the locking piece 75 is detached from the guide recess 73 along the curved surface that defines the guide recess 73. The claw 751 moves in the clockwise direction D1 along the outer peripheral surface of the inner cylindrical portion 41 in a state where the locking piece 75 is bent radially outward.

  When the locking projection 66 is disposed in the second portion 614, the locking projection 66 is restricted from moving forward in the direction of the rotation axis A1 by the guide surface 615. On the other hand, since the width of the second portion 614 of the guide groove 61 is larger than the width of the locking projection 66 in the direction of the rotation axis A1 (front-rear direction (left-right direction in FIG. 11)), the guide surface 615 and the rear flange 43 In the meantime, a certain amount of rearward movement is allowed, but the allowable movement range varies depending on the thickness of the fan mounting portion 93 (clothing) disposed on the front side of the rear flange 43.

  Depending on the thickness of the fan mounting portion 93 of the outer garment 9, the user can place the locking projection 66 at the first locking position shown in FIG. 11 or the second locking position shown in FIG. The ring member 5 can be rotated in the clockwise direction D1. The first locking position is a position where the front end (the left end in FIG. 11) of the locking projection 66 contacts the first locking portion 616. The locking protrusion 66 abuts a step 618 formed on the downstream side of the first locking portion 616 at the downstream end in the clockwise direction D1 at the first locking position. The second locking position is a position where the front end (the left end in FIG. 13) of the locking projection 66 contacts the second locking portion 617. Note that the end of the locking projection 66 on the downstream side in the clockwise direction D <b> 1 contacts the end on the downstream side of the second portion 614 in the second locking position. Therefore, the user rotates the ring member 5 so that the front end surface of the locking projection 66 moves in the clockwise direction D1 along the guide surface 615, thereby moving the locking projection 66 to the first locking position or It can be moved easily and smoothly to the second locking position.

  A distance W1 in the facing direction between the front flange 53 and the rear flange 43 when the locking projection 66 is disposed at the first locking position (that is, in the direction of the rotation axis A1 and in the front-rear direction (left-right direction in FIG. 11)). 11 is larger than the distance W2 (see FIG. 13) between the front flange 53 and the rear flange 43 when the locking protrusion 66 is disposed at the second locking position. The distance between the rear flange 43 corresponds to the thickness of the fan mounting portion 93 (clothing) that can be clamped between the front flange 53 and the rear flange 43. Therefore, the user can wear the jacket 9 relatively thick. When the outer cover 9 is manufactured from a relatively thin material, the ring member 5 is rotated until the locking projection 66 is disposed at the first locking position. The locking projection 66 is arranged at the second locking position. It is sufficient to rotate the ring member 5 until.

  When the locking protrusion 66 is disposed at the first locking position, the reference protrusion mark 63 illustrated in FIG. 4 is disposed at a position facing the first position mark 621 of the inner cylinder portion 41. Thereby, the user can easily recognize that the locking projection 66 is disposed at the first locking position. As shown in FIG. 12, when the locking projection 66 is disposed at the first locking position, the claw 751 of the locking piece 75 enters the first recess 711 by the restoring force of the locking piece 75. , Engages the surface 712. As a result, the locking piece 75 is locked by the first recess 711. Further, the fastener 81 shown in FIG. 4 is disposed at a position facing the first holding portion 831.

  When the thickness of the fan mounting portion 93 is relatively close to the distance W1, the fan mounting portion 93 is located between the front flange 53 and the rear flange 43 when the locking protrusion 66 is disposed at the first locking position. It is clamped stably. The locking protrusion 66 is locked to the first locking portion 616 in the front, so that the ring member 5 is separated from the housing 4 in the direction of the rotation axis A1 (in other words, the front flange 52 is separated from the rear flange 43). Direction) is restricted. Further, the locking piece 75 is locked to the first recess 711 in the circumferential direction, so that the ring member 5 is restricted from rotating in the circumferential direction (in particular, the counterclockwise direction D2). Furthermore, as shown in FIG. 10, when the user rotates the fastener 81 to the fixed position and engages the first holding portion 831, the ring member 5 moves in a direction away from the housing 4, and the ring The member 5 is restricted from rotating in the circumferential direction. Thereby, the ring member 5 is stably fixed to the housing 4, and the blower 1 is securely attached to the outer jacket 9.

  On the other hand, when the jacket 9 is made of a relatively thin material and the thickness of the fan mounting portion 93 is relatively small with respect to the distance W1, the movement of the locking projection 66 in the direction of the rotation axis A1 is allowed to some extent. Therefore, the mounting of the blower 1 on the outer jacket 9 is not stable. Therefore, the user rotates the ring member 5 so that the locking projection 66 moves further downstream in the clockwise direction D1 than the first locking position. At this time, the claw 751 of the locking piece 75 once entering the first recess 711 is detached from the first recess 711 along the surface 713 that is a gentle inclined surface. The claw 751 moves in the clockwise direction D1 along the outer peripheral surface of the inner cylindrical portion 41 in a state where the locking piece 75 is bent radially outward.

  When the locking projection 66 is arranged at the second locking position, the reference projection mark 63 shown in FIG. 4 is arranged at a position facing the second position mark 627 of the inner cylinder portion 41. Thereby, the user can easily recognize that the locking projection 66 is disposed at the second locking position. As shown in FIG. 14, when the locking projection 66 is disposed at the second locking position, the claw 751 of the locking piece 75 enters the second recess 716 by the restoring force of the locking piece 75. Engaging the surface 717. Further, the fastener 81 shown in FIG. 4 is disposed at a position facing the second holding portion 836.

  When the thickness of the fan mounting portion 93 is relatively close to the distance W2 between the front flange 53 and the rear flange 43, the fan mounting portion 93 is stably clamped between the front flange 53 and the rear flange 43. Is done. When the locking projection 66 is locked to the second locking portion 617 on the front side, the movement of the ring member 5 in the direction away from the housing 4 (forward) is restricted in the direction of the rotation axis A1. Further, the locking piece 75 is locked to the second recess 716 in the circumferential direction, so that the ring member 5 is restricted from rotating in the circumferential direction. Furthermore, when the user engages the fastener 81 with the second holding portion 836, the movement of the ring member 5 in the direction away from the housing 4 and the rotation of the ring member 5 in the circumferential direction are restricted. Thereby, the ring member 5 is stably fixed to the housing 4, and the blower 1 is securely attached to the outer jacket 9.

  The user first removes the ring member 5 from the housing 4 when removing the blower 1 from the jacket 9. The user bends the pair of locking pieces of the first holding portion 831 or the second holding portion 836 in a direction close to each other, and moves the fastener 81 to the release position. The user further presses the tab 756 of the locking piece 75 locked to the first recess 711 or the second recess 716 in the counterclockwise direction D2 (or picks it with a finger and pulls it radially outward). B) The locking piece 75 is bent and the locking is released. Thereby, the movement of the ring member 5 with respect to the housing 4 in the circumferential direction is allowed. The user rotates the ring member 5 in the counterclockwise direction D <b> 2 with respect to the housing 4, and moves the locking protrusion 66 from the second portion 614 into the first portion 611. Then, the ring member 5 is moved forward relative to the housing 4, and the locking projection 66 is detached from the first portion 611. The user removes the ring member 5 from the housing 4 and then removes the main body 3 from the outer jacket 9.

  When the ring member 5 is attached to or detached from the housing 4, the user puts his / her finger on the finger-hanging recess 432 formed on the rear flange 43 or the finger-hooking protrusion 55 provided on the ring member 5, so that the housing 4 The ring member 5 can be gripped, and both can be relatively rotated in the circumferential direction, or can be relatively moved in the direction of the rotation axis A1. Thereby, attachment / detachment operation can be performed easily.

  As described above, in the present embodiment, as the locking mechanism 6, the three locking protrusions 66 are provided for the three guide grooves 61, and when the ring member 5 is attached to and detached from the housing 4, each pair is The relationship is engaged. On the other hand, for the rotation restricting mechanism 7, only one locking piece 75 is provided for the three sets of rotation locking portions 71. Further, with respect to the additional locking mechanism 8, one fastener 81 is provided for one set of fastener holders 83.

  Due to such a configuration, as in the above example, alignment is performed using the reference protrusion mark 63 and the fastener 81 is engaged with the first holding portion 831 or the second holding portion 836. In the three sets of rotation locking portions 71, only one specific set is used for locking the locking pieces 75. However, when the user does not use the additional locking mechanism 8, the positioning by the reference protrusion mark 63 is not particularly performed, and the locking piece 75 is set to any one of the three sets of the rotation locking portions 71. It only has to be locked to. From this point of view, three reference projection marks 63 are provided so as to correspond to all three locking projections 66, and three sets of first positions are set so as to correspond to all three sets of rotation locking portions 71. A mark 621 and a second position mark 627 may be provided.

  As described above, the user can attach / detach the blower 1 to / from the clothes having the outer garment 9 or the fan attachment portion 93. In the present embodiment, the blower device 1 holds the fan mounting portion 93 between the rear flange 43 and the front flange 53 that are opposed to each other in the direction of the rotation axis A <b> 1, and the ring member 5 is attached to the housing 4 by the locking mechanism 6. On the other hand, the ring member 5 is prevented from being detached from the housing 4 by being locked in the direction of the rotation axis A1. In the present embodiment, as the locking position of the locking projection 66 in the direction of the rotation axis A1, the first locking portion 616 and the second locking portion 617 that are different in the position in the rotation axis A1 direction are provided. The blower 1 can correspond to a plurality of types of clothes having different thicknesses.

  In particular, the first locking portion 616 and the second locking portion 617 are on a path through which the locking protrusion 66 can pass in the process in which the user attaches the ring member 5 to the housing 4 along a predetermined operation line ( Specifically, it is formed in the guide groove 61 (guide surface 615). Therefore, the user may lock the locking protrusion 66 at one of the appropriate locking positions in a series of mounting operations. That is, the user does not need to remove the ring member 5 from the housing 4 and remount it in order to change the locking position. Thus, the air blower 1 of this embodiment can respond to multiple types of clothes having different thicknesses with an easy operation.

  Furthermore, the ring member 5 is mounted on the housing 4 by moving relative to the housing 4 in the order of the rotation axis A1 (rear) and the circumferential direction (clockwise direction D1) along the operation line. The first locking portion 616 and the second locking portion 617 are provided in the second portion 614 extending in the circumferential direction in the guide groove 61. Therefore, unless the locking projection 66 is once moved in the circumferential direction (counterclockwise direction D2), the locking in the direction of the rotation axis A1 with respect to the first locking portion 616 or the second locking portion 617 may be released. Absent.

  Further, the rotation restricting mechanism 7 restricts the ring member 5 from moving in the circumferential direction (counterclockwise direction D2) with respect to the housing 4. With this configuration, the possibility that the ring member 5 is detached from the housing 4 can be further reliably suppressed. The locking piece 75 is configured to be locked to the first concave portion 711 or the second concave portion 716 in accordance with the rotation operation of the ring member 5 with respect to the housing 4 in the circumferential direction (clockwise direction D1). For this reason, the user can operate both the locking mechanism 6 and the rotation restricting mechanism 7 only by an operation of mounting the ring member 5 on the housing 4 along a predetermined operation line.

  In the present embodiment, in addition to the locking mechanism 6 and the rotation restricting mechanism 7, an additional locking mechanism 8 that restricts the movement of the ring member 5 relative to the housing 4 in the direction of the rotation axis A1 and the rotation in the circumferential direction is provided. Yes. Therefore, even if the locking mechanism 6 or the rotation restricting mechanism 7 does not function, the additional locking mechanism 8 can perform its function, so that the possibility that the ring member 5 can be detached from the housing 4 is further ensured. Can be suppressed.

  Furthermore, since the color of the ring member 5 is different from that of the housing 4, the user can clearly distinguish the ring member 5 and the housing 4 visually. Thereby, since it can be understood immediately which member should be relatively moved with respect to which member, attachment / detachment operation (especially operation which removes the ring member 5 from the housing 4) becomes easy.

  The said embodiment is only an illustration, and the air blower and clothing which concern on this invention are not limited to the structure of the air blower 1 and the jacket 9 which were illustrated. For example, the structure of the air blower 1 or the jacket 9 can be appropriately changed according to a desired additional function. With reference to FIGS. 15-19, the air blower 10 and the jacket 9 which concern on a modification are demonstrated. In the following, for the sake of convenience, the same reference numerals are assigned to the same configurations (including essentially the same configurations although there are slight differences) as the blower device 1 of the above embodiment (see FIGS. 3 to 14). The description and illustration will be omitted or simplified as appropriate.

  First, the blower 10 will be described. As shown in FIGS. 15 to 17, the blower device 10 includes a main body 30 and a ring member 50. The main body 30 includes a motor 33 and a fan 36 having the same configuration as the main body 3 of the above embodiment. The housing 40 and the ring member 50 of the main body 3 are provided with a locking mechanism 6 (see FIG. 4) having the same configuration as that of the above embodiment, and a rotation restricting mechanism 7 (see FIG. 4) having a slightly different configuration. .

  In the rotation restricting mechanism 7 of this modification, only the tab 757 of the locking piece 75 is slightly different from the tab 756 (see FIG. 12) of the above embodiment. Specifically, as shown in FIG. 12, the tab 756 of the above embodiment protrudes to substantially the same position as the edge of the front flange 53, whereas as shown in FIG. 15 and FIG. Then, the tab 757 protrudes radially outward from the edge of the front flange 53. With this configuration, when removing the ring member 50 from the housing 40, the user can easily grasp the position of the tab 757 to be operated. Further, the tip portion of the tab 757 (specifically, the portion protruding radially outward from the edge of the front flange 53) is a color different from the other portions of the ring member 50. Thereby, the visibility of the tab 757 can be further improved.

  Further, in this modification, the additional locking mechanism 8 (see FIG. 4) is not provided. In such a case, as described in the above embodiment, the user may associate the three locking protrusions 66 with the three guide grooves 61 in any way. For this reason, as shown in FIGS. 15 and 16, the housing 40 and the ring member 50 are provided with three reference protrusion marks 63 and three sets of first position marks 621 and second position marks 627.

  Furthermore, as described in the above embodiment, in the process of mounting or removing the ring member 50 from the housing 40, the user needs to rotate the ring member 50 in the circumferential direction with respect to the housing 40. Therefore, in the present embodiment, the rotation direction display portion 57 is provided on the flange-shaped front end surface of the outer cylindrical portion 51 of the ring member 50. The rotation direction display unit 57 includes a first mark 571 (an arrow and a locked key pattern) indicating the rotation direction of the ring member 50 at the time of attachment, and a second mark 572 (an indication of the rotation direction of the ring member 50 at the time of removal). Arrow and unlocked key symbol).

  As shown in FIGS. 15 to 17, the housing 40 is provided with an engagement arm 481. The engagement arm 481 is configured to be engageable with a fan holding belt 98 (see FIGS. 19 and 20) provided on an outerwear 90 described later. Specifically, a region where the first rib 463 is not provided is provided in a part of the exhaust portion 46 in the circumferential direction. This region constitutes a belt passing region 48 when the fan holding belt 98 is attached to the engagement arm 481. The engagement arm 481 is a substantially U-shaped portion that is supported on both sides of the belt passing region 48 in the circumferential direction and protrudes forward. The mounting of the fan holding belt 98 will be described later.

  Also in this modification, the housing 40 is provided with a connector arrangement region 38 similar to the housing 4 of the above embodiment. As shown in FIGS. 16 and 17, when the connector 973 of the cable 97 is connected to the connector 37 of the main body 3 and is arranged in the connector arrangement region 38, the regulation rib 381 comes into contact with the connector 973 from the outside in the radial direction, The connector 973 is prevented from being disconnected.

  Next, a description will be given of a jacket 90 configured so that the blower 10 can be attached and detached. As shown in FIG. 18, the outerwear 90 includes a hood 900 that is sewn integrally to the body part. Therefore, when the blower 10 is mounted on the outer garment 90, the air sent into the outer garment 90 can flow to the hood 900 to cool the user's head. The hood 900 may be detachable from the body with fasteners or buttons.

  Most of the outer garment 90 including the hood 900 is formed of a natural fiber, a synthetic fiber, or a blended fabric thereof (including a fabric that is surface-treated so that air does not easily leak outside). On the other hand, a mesh portion 903 using mesh fabric is provided in a predetermined region corresponding to a position facing both ears when the user wears the hood 900 among the hood 900. Thereby, even when the user wears the hood 900, it is easy to hear surrounding sounds. Note that the mesh portion 903 may be shielded by a flap (not shown).

  As shown in FIG. 19, the jacket 90 has mounting openings 91 (fan mounting portions 93) formed at two locations on the back surface portion, like the jacket 9 (see FIG. 8) of the above embodiment. Furthermore, in this modification, a fan holding belt 98 is attached to the back surface of the jacket 90. The fan holding belt 98 is configured to prevent the blower 10 from falling off the outer jacket 90 by engaging with the engagement arm 481 of the blower 1 described above. More specifically, the fan holding belt 98 is formed in a band shape with a flexible material (for example, a cloth), and one end thereof is sewn to the outer jacket 90 above the fan mounting portion 93. A pair of hook buttons (snap buttons) 981 are attached to both ends of the fan holding belt 98. Therefore, as shown on the right side of FIG. 19, when the hook button 981 is removed, the fan holding belt 98 extends in a band shape with one end being a free end. On the other hand, as shown on the left side of FIG. 19, when the hook button 981 is fastened, the fan holding belt 98 has a loop shape and both ends are fixed to the jacket 90.

  The usage mode of the fan holding belt 98 will be described with reference to FIGS. 19 and 20. As shown on the right side of FIG. 19, the user puts the air blower 10 on the fan mounting portion 93 of the jacket 90 as described in the above embodiment with the hook button 981 of the fan holding belt 98 removed. Install. Then, as shown in FIG. 20, the fan holding belt 98 is passed through the belt passing region 48, the fan holding belt 98 is looped in a state of surrounding the engaging arm 481, and the hook button 981 is fastened, whereby the jacket 9 Attach to. Thereby, even if the locking of the locking mechanism 6 is released for some reason, it is possible to prevent the fan holding belt 98 from falling off the main body 30 from the fan mounting portion 93. For this reason, possibility that the motor 33 and the fan 36 which were accommodated in the housing 40 will be damaged can be reduced.

  In addition, when the main-body part 30 remove | deviates from the fan attachment part 93, it will drop | omit to the outer side of the jacket 90 in which the rear side flange 43 is arrange | positioned. In this modification, a fan attached to the inner side of the outer jacket 90 with respect to an engagement arm 481 provided in a portion (in detail, the exhaust portion 46) of the housing 40 disposed inside the outer jacket 9. A holding belt 98 is engaged. Therefore, the fan holding belt 98 can hold the main body 30 more reliably as compared with the case where a drop-off prevention mechanism is provided outside the outer jacket 90. In addition, since the fan holding belt 98 is disposed on the side of the ring member 50 in the direction away from the housing 40, not only the main body 30 but also the ring member 50 can be prevented from falling off. .

  In addition, if the blower 10 rotates with respect to the jacket 90 with the driving of the motor 33 and the rotation of the fan 36, an extra load may be applied to the cable 97 and the blower 10. Moreover, the direction of the closing part 451 (refer FIG. 6) comprised as a design surface may change to the direction different from the original. On the other hand, the fan holding belt 98 can function not only as a drop-off prevention mechanism but also as a rotation restricting mechanism that restricts the air blower 10 from rotating with respect to the jacket 90.

  In this modification, the engagement arm 481 is a configuration example corresponding to the “engagement portion” of the present invention. The fan holding belt 98 having the hook button 981 is a configuration example corresponding to the “drop-off prevention mechanism” of the present invention. In addition, the engagement aspect of the engaging part and the drop-off prevention mechanism and the arrangement position thereof are not limited to those illustrated in the present modification, and may be appropriately changed. For example, as another configuration example of the drop-off prevention mechanism, one end portion is attached to the jacket 90 and the other end portion has a hook member that can be engaged with the engagement arm 481, and one end portion is attached to the jacket 90. For example, a string-like member that can tie the other end to the engagement arm 481 can be used. Further, for example, a hook is employed instead of the engagement arm 481, a belt-shaped member having an annular member that is attached to the outer jacket 90 at one end and engageable with the hook at the other end instead of the fan holding belt 98. Or a string-like member may be adopted.

In addition to the above modifications, the modifications exemplified below can be added. It should be noted that only one or more of these changes can be applied to the blower 1, 10 and the jacket 9, 90 shown in the embodiment and the modification, or the invention described in each claim. Can be used in combination.

  As long as the ring member 5 is configured to be detachable from the housing 4, the configurations of the housing 4 and the ring member 5 may be appropriately changed. For example, the configuration of the intake portion 45 and the exhaust portion 46 of the housing 4 (arrangement of the intake port 457 and the exhaust port 467) may be changed. From the viewpoint of ease of attachment / detachment operation, it is preferable that the housing 4 has a cylindrical portion at least partially, and the ring member 5 has a cylindrical portion that can be fitted onto the cylindrical portion of the housing 4.

  The configuration that can hold the fan mounting portion 93 (clothing) is not limited to the rear flange 43 and the front flange 53. For example, the rear flange 43 and the front flange 53 do not necessarily have to surround the entire circumference of the inner cylinder part 41 and the outer cylinder part 51, for example, a part in the circumferential direction may be cut out, or a part thereof An opening may be provided in. The rear flange 43 and the front flange 53 preferably have substantially the same outer diameter from the viewpoint of more reliably holding the clothes, but the outer diameters may be different.

  The locking mechanism 6 only needs to be configured to lock the ring member 5 in the direction of the rotation axis A1 with respect to the housing 4 so as to restrict the movement of the ring member 5 in the direction of the rotation axis A1 with respect to the housing 4. The configurations provided in the housing 4 and the ring member 5 are not limited to the guide groove 61 and the locking projection 66. For example, the arrangement relationship may be reversed, and the locking protrusion 66 may be provided on the outer peripheral surface of the housing 4, while the guide groove 61 may be provided on the inner peripheral surface of the ring member 5. The number of guide grooves 61 and locking projections 66 is not limited to three sets, but a plurality of sets are preferably provided from the viewpoint of more reliable locking.

  Further, the shape of the guide groove 61 and the locking projection 66, the locking position of the locking projection 66, and the like may be changed as appropriate. For example, the guide groove 61 may be formed as a through hole instead of a recess. Furthermore, in order to be able to cope with the difference in the thickness of the clothing more finely, there may be provided three or more locking positions where the locking projection 66 is locked in the direction of the rotation axis A1.

  Further, the operation line (mounting direction) when the ring member 5 is mounted on the housing 4 can be changed as appropriate. In the above-described embodiment, the guide surface 615 of the guide groove 61 is formed so as to be gently inclined backward in the clockwise direction D1, so that the operation of rotating the ring member 5 and the first locking are performed. The operation of moving the locking projection 66 to the portion 616 or the second locking portion 617 can be performed smoothly without distinction. However, the guide surface 615 may be formed in a stepped shape including surfaces corresponding to the first locking portion 616 and the second locking portion 617. For example, a second portion extending in the clockwise direction D1 and a third portion extending in the counterclockwise direction D2 may be provided on both sides of the first portion 611, respectively. The wall surface that defines the front end of the second part and the wall surface that defines the front end of the third part may be different in position in the direction of the rotation axis A1. In this case, after the ring member 5 is moved relative to the housing 4 in the direction of the rotation axis A1 (rearward), the ring member 5 is moved relative to the clockwise direction D1 or the counterclockwise direction D2 depending on the thickness of the clothing. become.

  Further, for example, a locking mechanism 600 including a locking portion 64 and a locking piece 67 may be employed instead of the locking mechanism 6 as in the modification shown in FIG. In FIG. 21, for simplification, only a partial cross section of the inner cylindrical portion 410 of the housing 4 and the outer cylindrical portion 510 of the ring member 5 is schematically shown.

  The locking portion 64 is formed by a plurality of locking grooves 640 having a V-shaped cross section formed along the rotation axis A1 direction (front-rear direction) on the outer peripheral surface of the inner cylindrical portion 410. Of the two surfaces defining each locking groove 640, the front surface 641 (the left surface in FIG. 21) is arranged so as to be substantially orthogonal to the rotation axis A1, and the rear surface 642 (the right surface in FIG. 21). The surface) is arranged so as to incline in the diameter expansion direction toward the rear. Each locking groove 640 defines the locking position of the locking piece 75. On the other hand, the locking piece 67 is integrally formed with the outer cylindrical portion 510 so as to extend in the central axis A2 direction (front-rear direction) of the outer cylindrical portion 510 as a flexible band-shaped member. The locking piece 67 has the same configuration as the locking piece 75 (see FIG. 12) of the above-described embodiment, and a claw 671 that can be locked in the locking groove 640 on the inner side of the rear end portion that is the front end portion. And a tab 672 on the outside. It is preferable that a plurality of the locking portions 64 and the locking pieces 67 are provided in the circumferential direction of the inner cylindrical portion 410 and the outer cylindrical portion 510, respectively.

  In the blower provided with the locking mechanism 600, the ring member 5 is attached / detached by being relatively moved with respect to the housing 4 in the direction of the rotation axis A <b> 1. In other words, the ring member 5 does not need to be moved relative to the housing 4 in the circumferential direction, unlike the above-described embodiment, which is relatively moved in the order of the rotation axis A1 and the circumferential direction. For this reason, in this modification, the rotation restricting mechanism 7 may not be provided. However, from the viewpoint of more reliably avoiding the locking piece 67 from coming off from the locking portion 64 in the circumferential direction, for example, on both sides of the locking portion 64 in the circumferential direction, It is preferable that a wall portion that restricts movement in the direction is provided.

  When attaching the ring member 5 to the housing 4, the user aligns the locking portion 64 and the locking piece 67 so as to face each other in the radial direction. And the outer side cylinder part 510 is moved back with respect to the inner side cylinder part 410, and the locking piece 67 is locked to the appropriate locking groove 640 according to the thickness of the fan attachment part 93 (clothing). In this way, the user can simply insert the ring member 5 into the housing 4 by simply pushing the ring member 5 in the direction of the rotation axis A1 (specifically, rearward) to the appropriate locking position according to the clothing. Can be installed.

  Regarding the configurations of the rotation restricting mechanism 7 and the additional locking mechanism 8, similarly to the locking mechanism 6, the positional relationship between the rotation locking portion 71 and the locking piece 75 and the positional relationship between the fastener 81 and the fastener holding portion 83 are the same. Changes can be made as appropriate, such as reverse rotation. Further, the rotation restricting mechanism 7 and the additional locking mechanism 8 are not necessarily provided. In addition, when the additional locking mechanism 8 is used together with the locking mechanism 6, it is preferable to restrict at least the circumferential rotation of the ring member 5 with respect to the housing 4.
