  The electric fan of Patent Document 1 can be hung on a neck or held by hand when being carried. However, when the fan is hung on the neck, the fan also moves with the movement of a person, so that the blowing direction cannot be fixed in a desired direction.

  In addition, when the fan is held by hand, one hand is closed, and when using the fan while using the umbrella on a day with strong sunlight or a rainy day, both hands are closed. If there are other packages, holding them becomes complicated.

  On the other hand, in the electric fan of Patent Document 2, since the main body of the electric fan is fixed to the handle of the umbrella, the complexity of holding the electric fan is reduced. However, it is unknown whether the blowing direction can be changed up and down, and it is assumed that the only way to change the blowing direction is to tilt the handle of the umbrella. In addition, there is a description that the blades of the power conditioner and the electric fan can be removed, but there is no description about the mounting / detaching structure of the electric fan body, and there is a possibility that the attaching / detaching to / from the handle of the umbrella is complicated.

  As described above, there are various problems to be solved in the conventional portable electric fan, and there is a demand for an electric fan that can be easily attached to and detached from the handle of the umbrella and that can easily set the blowing direction.

  The characteristic configuration of the electric fan according to the present invention includes a main body and an opening / closing body that cooperate with each other to form a holding portion for the handle of the umbrella, and a blade unit that is connected to the main body via a first shaft so as to be changeable in posture. And an opening / closing body that switches between a closed state when attaching the main body to the handle and an open state when removing the main body from the handle is connected to the main body via a second shaft portion. is there.

(effect)
Since the blade unit is connected to the main body via the first shaft portion as in this configuration, the direction of the blade unit is changed and the blowing direction is set arbitrarily regardless of the mounting posture of the main body with respect to the handle of the umbrella. be able to.

  In addition, if the main body and the opening / closing body are connected via the second shaft portion and the opening / closing body can be opened and closed with respect to the main body when the electric fan is attached to the handle of the umbrella as in the present configuration, the main body with respect to the handle is provided. Installation becomes easier.

  In other words, since the opening and closing body is opened about the second shaft portion, the main body can be attached to the umbrella handle in a direction perpendicular to the umbrella handle. Can be mounted quickly.

  Further, since the opening / closing body is attached to the main body via the second shaft portion, the opening / closing body does not separate from the main body when the fan is attached to or detached from the handle of the umbrella. Therefore, it is also possible to hold the electric fan in one hand and attach it to the handle, so that the electric fan can be easily handled.

  A characteristic configuration of the electric fan according to the present invention is that at least one of the main body and the opening / closing body includes a cushion material that elastically contacts the handle when the opening / closing body is in the closed state.

(effect)
When the opening / closing body is closed as in this configuration, the cushion member elastically abuts the handle, so that the main body is less likely to rotate with respect to the handle, and is less likely to move along the longitudinal direction of the handle. Therefore, the direction of the blade unit is stabilized, and air can be sent to the user in a constant state.

  Further, since the cushion material has elasticity, it is possible to give a certain tolerance to the diameter of the handle that can be attached. Therefore, the versatility of the fan can be improved.

  The characteristic configuration of the electric fan according to the present invention is characterized in that the second shaft portion has a cylindrical shaft body formed on each of the side surfaces facing each other in the opening and closing body, and the two shafts of the opening and closing body in the main body. A long hole formed so that the shaft body can be inserted into a receiving surface arranged in a state opposed to each other, and which allows the opening and closing body to approach and contact the main body when the opening and closing body is in the open state; , With the point.

(effect)
As in the present configuration, an elongated hole is provided in the second shaft portion so that the opening / closing body can abut on the main body when the opening / closing body is in an open state, so that the opening / closing body when the main body is attached to the handle of the umbrella is provided. Damage can be prevented.

  For example, when the opening / closing body is opened and the handle of the umbrella is positioned on the holding portion to close the opening / closing body, the main body and the handle positioned on the holding portion of the main body may be simultaneously pressed with the left hand. At this time, since there is an edge of the back surface of the opening / closing body in the open position near the handle, the thumb of the left hand simultaneously pushes the back edge. This pushing force is relatively strong in order to securely hold the handle of the umbrella.

  If the shaft of the second shaft is inserted into the circular hole, the opening / closing operation of the opening / closing body with respect to the main body operates smoothly with the second shaft as a fulcrum. However, in order to prevent interference between the opening / closing body and the main body at the time of opening / closing, the peripheral portion of the opening / closing body is often separated from the main body, and only the shaft body comes into contact with the main body. As a result, when the pushing force of the thumb acts on the opening / closing body, the pushing force concentrates on the shaft body, and the shaft body may be damaged.

  Therefore, as in this configuration, the shaft of the opening / closing body in the open state moves along the long hole, and a portion of the opening / closing body that is different from the shaft comes into contact with the main body. The burden on the shaft can be eliminated. As a result, the durability of the second shaft portion can be improved.

  The characteristic configuration of the electric fan according to the present invention is such that, when the opening and closing body is in a closed state, at a position on the opposite side of the main body and the opening and closing body with respect to the holding portion in the opening and closing direction, the main body and the opening and closing body are closed. The locking portion and the locked portion that engage with the opening / closing body are formed separately.

(effect)
By providing the locking portion and the locked portion as in this configuration, the opening / closing operation of the opening / closing body becomes simple, and the attachment / detachment of the main body to / from the handle becomes extremely easy.

It is a perspective view showing the appearance of the electric fan concerning this embodiment. It is a perspective view showing the attachment state of the electric fan concerning this embodiment. FIG. 3 is an exploded perspective view showing main parts of the electric fan. It is explanatory drawing which shows the opening and closing operation | movement of an opening / closing body.

(Overview)
1 to 4 show an embodiment of a fan S according to the present invention. As shown in FIG. 1A, the electric fan S includes a main body 1 and a blade unit 2 that is connected to the main body 1 via a first shaft J1 so as to be able to change its posture. Thereby, the blowing direction can be changed.

  The main body 1 includes an opening / closing body 3 that is connected to the main body 1 via a second shaft J2 so as to be freely opened and closed. When the main body 1 is attached to the handle P, the first opposing surface F1 of the opening / closing body 3 is in a closed state facing the second opposing surface F2 of the main body 1, and the main body 1 and the opening / closing body 3 form a holding portion H. You. When the main body 1 is detached from the handle P, the opening / closing body 3 is opened.

  According to this configuration, the opening / closing body 3 is opened around the second shaft portion J2, and the main body 1 can be attached to the handle P of the umbrella in a direction perpendicular to the handle P. Therefore, the main body 1 can be quickly and easily attached to any position of the handle P.

  In addition, when the fan S is attached to and detached from the handle P of the umbrella, the opening / closing body 3 does not separate from the main body 1, and the user can attach the fan S to the handle P with one hand, so that the handling of the fan S becomes easy.

(Blade unit)
The blade unit 2 includes a drive motor 22 and blades 23 inside a mesh-shaped cover 21 divided into front and rear portions. The cover 21 includes a front cover 21a and a rear cover 21b. The front cover 21a is joined to the rear cover 21b by four joints having a bayonet structure.

  The drive motor 22 is attached to the rear cover 21b, and includes a coil fixed to the rear cover 21b, a cylindrical permanent magnet disposed around the coil, and a blade 23 fixed to the permanent magnet. Have.

  The drive motor 22 is connected to a charging battery and a control circuit provided inside the main body 1. Charging of the charging battery is performed using a charging terminal 16 provided on the main body 1. The speed of the drive motor 22 can be controlled in multiple stages by operating a switch 24 (FIG. 1B) provided with a push-push type switching mechanism provided on the side surface of the main body 1. An indicator 25 using an LED indicating that the switch 24 is ON is provided on the second facing surface F2 of the main body 1.

  Although not shown, the first shaft portion J1 for attaching the blade unit 2 to the main body 1 is provided with a first shaft body provided on the blade unit 2 and the first shaft body provided on the main body 1 to rotatably support the first shaft body. A first bearing. A spur gear is fixed to a part of the first shaft body, and the other main body 1 is provided with a click member that elastically contacts the spur gear. Thus, when the angle of the blade unit 2 is changed, the feel that the click member gets over the teeth of the spur gear one by one is obtained, and the posture of the blade unit 2 can be fixed at the intermittent position.

(Structure of main body and opening / closing body)
FIGS. 2 and 3 show the structure of the second shaft portion J2 in the present embodiment. Of the side surfaces of the opening / closing body 3, two side surfaces F <b> 3 which are orthogonal to each other while being orthogonal to the longitudinal direction X of the main body 1, are formed with a cylindrical shaft body 31 projecting along the longitudinal direction X.

  On the other hand, in the main body 1, a long hole 11 into which the shaft body 31 can be inserted is formed on a receiving surface F <b> 4 arranged to face each of the two side surfaces F <b> 3 of the opening / closing body 3. The elongated hole 11 is a bearing of the shaft 31 for rotating the opening / closing body 3 and allows the opening / closing body 3 to approach and come into contact with the main body 1 when the opening / closing body 3 is open. is there.

  One of the two shafts 31 is provided on a flexible portion 32 formed to be flush with the side surface F3. Incidentally, the opening / closing body 3, the flexible portion 32 and the shaft body 31 are integrally formed of a resin material. Accordingly, when the opening / closing body 3 is mounted between the receiving surfaces F4, the flexible portion 32 bends and deforms with respect to the opening / closing body 3, thereby facilitating the operation of inserting the two shaft bodies 31 into the elongated holes 11. ing.

  FIG. 4 shows how the posture of the opening / closing body 3 changes when the opening / closing body 3 is opened / closed. When the opening / closing body 3 is opened from the state shown in FIG. 4A to the state shown in FIG. 4B, the opening / closing body 3 rotates about the shaft 31. At this time, the corner 33 of the first facing surface F1 of the opening / closing body 3 moves along an arc-shaped locus about the shaft 31. Therefore, an arc-shaped groove portion 12 is formed on the second facing surface F2 of the main body 1 so as to prevent interference with the corner portion 33.

  When the opening / closing body 3 further opens, and the corner 33 is separated from the groove 12 as shown in FIG. 4C, the entire opening / closing body 3 can approach the second facing surface F2. At this time, the shaft body 31 moves along the long hole 11. Further, in the state shown in FIG. 4D in which the opening / closing body 3 is completely opened, the opening / closing body 3 comes closest to the main body 1, and the surface 34 of the opening / closing body 3 comes into contact with the second facing surface F <b> 2 of the main body 1. . This posture of the opening / closing body 3 is a posture when the main body 1 is attached to the handle P of the umbrella.

  Such an operation mode of the opening / closing body 3 has an effect of preventing damage to the opening / closing body 3 when the main body 1 is attached to the handle P of the umbrella. For example, when the opening / closing body 3 is opened and the handle P of the umbrella is positioned on the holding portion H and the opening / closing body 3 is closed, the main body 1 and the handle P positioned on the holding portion H of the main body 1 are simultaneously held with the left hand. It can be suppressed. At this time, since the edge of the first facing surface F1 of the opening / closing body 3 in the open position, that is, the corner 33 is located near the handle P, the thumb of the left hand also presses the corner 33 at the same time. . This pushing force is relatively strong in order to securely hold the handle P of the umbrella.

  If the hole through which the shaft body 31 is inserted is circular, the opening / closing operation of the opening / closing body 3 with respect to the main body 1 can be smooth around the circular hole. However, if a circular hole is provided and the movement of the opening / closing body 3 with respect to the main body 1 is limited to only the rotational movement, the corner 33 of the opening / closing body 3 is formed with the second part of the main body 1 in order to prevent the interference of the opening / closing body 3 with the main body 1. It is necessary to keep it away from the facing surface F2. In this case, only the shaft 31 of the opening / closing body 3 comes into contact with the hole of the main body 1, and the pushing force acting on the opening / closing body 3 is concentrated on the shaft 31, and the shaft 31 may be damaged.

  Further, when the corner 33 is separated from the second facing surface F2 of the main body 1 when the opening / closing body 3 is in the closed state, the existence of the gap becomes clear and the design may be impaired.

  Therefore, as in the present configuration, the shaft 31 of the opening / closing body 3 that performs the opening operation is configured to be movable along the elongated hole 11, and in the opening posture, for example, a surface 34 of the opening / closing body 3 that is different from the shaft 31. Is in contact with the second facing surface F2 of the main body 1. Thereby, the burden on the shaft body 31 at the time of mounting can be eliminated, and the durability of the second shaft portion J2 can be increased.

  Further, since the main body 1 is formed by resin molding, it is easy to form the elongated hole 11 in the receiving surface F4 of the main body 1 that faces each of the two side surfaces F3 of the opening / closing body 3. For example, at the time of resin molding, usually, a cutting die on the front side and a cutting die on the back side are pressed against each other to form a cavity serving as a resin portion of the main body 1. At this time, by forming a bank portion on one of the punches so that the resin is not filled in a part of the wall forming the receiving surface F4, the wall is not formed on a part of the receiving surface F4. It becomes a long hole 11. As a result, even when the main body 1 is formed by two punching dies, a hole perpendicular to the moving direction of the punching die can be formed, and the main body 1 having the long holes 11 can be easily obtained.

  As shown in FIGS. 2 and 3, in the present embodiment, the locking portion 41 and the engaged portion are located at positions opposite to the second shaft portion J2 with respect to the holding portion H of the main body 1 and the opening / closing body 3. Stop portions 42 are separately formed, and engage the main body 1 and the opening and closing body 3 when the opening and closing body 3 is in the closed state.

  The locking portion 41 is integrally formed so as to protrude from the first facing surface F1 of the opening / closing body 3 facing the main body 1 toward the main body 1 and has a hook-like shape having an inclined surface 41a at the tip. A locking claw 41b is formed.

  On the other hand, the locked portion 42 provided on the main body 1 includes a locked claw 42b that engages with the locking claw 41b. The locked portion 42 is slidable along the longitudinal direction X of the main body 1 by a guide portion provided on the inner surface of the main body 1. A rod-shaped first spring receiver 42a projecting toward the inside of the main body 1 is formed in the locked portion 42, and one end of the extension coil spring 5 is connected to the first spring receiver 42a. The other end of the extension coil spring 5 is connected to a second spring receiver 13 formed on the inner surface of the main body 1. Thereby, the locked portion 42 is constantly urged in the direction in which the locked claw 42b engages with the locking claw 41b.

  An opening 14 that exposes a part of the locked portion 42 is formed in the second facing surface F2 of the main body 1. That is, the locking claw 41b enters the opening 14 by the closing operation of the opening / closing body 3, and engages with the locked claw 42b. When the locking claw 41b is engaged with the locked claw 42b, the inclined surface 41a of the locking claw 41b presses the locked claw 42b, and the locked portion 42 resists the urging force of the extension coil spring 5. To slide. When the inclined surface 41a of the locking claw 41b gets over the locked claw 42b, the locked portion 42 is pulled back to the extension coil spring 5, and both are locked.

  The second opening 15 is formed in the side surface F5 of the main body 1, and the operation portion 43 of the slidable locked portion 42 is exposed from the second opening 15. To release the engagement of the locking claw 41b in the locked state, the operating portion 43 is slid against the urging force of the extension coil spring 5 to disengage the locking claw 41b from the locked claw 42b.

  By providing the locking portion 41 and the locked portion 42 as in this configuration, the opening / closing operation of the opening / closing body 3 becomes simple, and the attachment / detachment of the main body 1 to / from the handle P of the umbrella becomes extremely easy.

(Cushion material)
In order to securely fix the main body 1 to the handle P of the umbrella, a cushion material 6 may be provided on at least one of the main body 1 and the opening / closing body 3. The cushion material 6 is made of, for example, various resin materials having elasticity. In the electric fan S of the present embodiment, the cushion member 6 is provided on the first facing surface F1 of the opening / closing body 3. The thickness of the cushion member 6 is set so that the cushion member 6 abuts on the handle P and is elastically deformed when the opening / closing body 3 is in the closed state. Since the thickness of the handle P differs depending on the umbrella used, for example, a cushion material 6 having several types of thicknesses is prepared according to the diameter of the handle P of the umbrella frequently used by the user, and the user can use the optimal cushion material. 6 may be attached to the back surface of the opening / closing body 3.

  Since the cushion member 6 has elasticity as described above, a certain allowable range can be given to the diameter of the handle P that can be attached, and the versatility of the electric fan S can be increased.

  In addition, if the cushion material 6 can generate a large frictional force with respect to the handle P of the umbrella in addition to the elasticity, the main body 1 becomes difficult to rotate with respect to the handle P, It is difficult to move along. Therefore, the direction of the blade unit 2 is stabilized, and air can be sent to the user in a constant state.

(Example of use)
As shown in FIG. 2, the electric fan S according to the present embodiment, when the blade unit 2 is bent with respect to the main body 1 and attached to a position below the handle P of the umbrella, blows air upward from below to the user. can do. When the umbrella is attached to the position below the handle P, the center of gravity of the umbrella is lowered, so that the umbrella can be easily held.

  On the other hand, although not shown, the blade unit 2 may be mounted on the umbrella handle P in the state shown in FIG. In this case, the blowing direction is downward, and the blowing to the chest and the like becomes easier.

  As another usage example, the user may hold the main body 1 by hand. In that case, the direction of the blade unit 2 may be appropriately selected. Further, the blade unit 2 may be appropriately bent and the surface 34 of the opening / closing body 3 may be placed in contact with the desk surface.

  The present invention can be widely applied to various portable electric fans.
