Description

The present invention relates to a oscillating device, and more particularly, to an improvement of an oscillating device incorporated in a fan, an oscillating electric stove, or the like.

(B) Conventional technology Conventionally, as this kind of a swinging device, one described in Japanese Patent Application Laid-Open No. 1-238798 is known. This oscillating device includes an apparatus main body, a support that pivotally supports a pivot suspended from the apparatus main body, a left and right oscillating motor mounted on the support, and a left and right oscillating motor having the pivot as a rotation center. Swiveling oscillating body (neckpiece upper)
And a connecting body that is connected to the oscillating rotator via an engagement / disengagement mechanism and rotates integrally with the apparatus main body.

(C) Problems to be solved by the invention In the oscillating device described in the above publication, in order to obtain a double oscillating function (a function of changing the range of left and right oscillating to left or right), A swing body and a connecting body are provided. For this reason, there are problems that the number of parts is large, the cost is high, and the workability of assembly is poor.

The present invention has been made in view of the above circumstances,
An object of the present invention is to provide a swinging device that has a small number of parts, can reduce costs, and has excellent assembling workability.

(D) Means for Solving the Problems and Action Thereof The present invention relates to a neckpiece for supporting a body of a oscillating device, a left and right oscillating motor provided in the neckpiece, and a motor for oscillating the body of the oscillating device. A motor leg for supporting the up-and-down oscillating motor, and a spindle provided on the motor leg so as to protrude downward.Furthermore, the cylindrical body has the spindle inserted therein, and has an upper surface. Abuts on the underside of the motor leg,
A neck piece upper provided with a concave portion on the upper surface side, an upper urging member fitted in the concave portion, and a motor disposed on the upper urging member and urged upward by the upper urging member to A locking member pressed against the lower surface of the leg, a plurality of locking members provided on the motor leg corresponding to the concave portion, a locking portion into which the locking member is removably fitted, and provided on the neck piece upper, An oscillating device comprising: an engagement claw that engages with an arc-shaped long hole formed in a motor leg.

That is, instead of the conventional combination of the oscillating body (neckpiece upper) and the connecting body, the oscillating device according to the present invention includes a neckpiece upper having a concave portion on the upper surface side and fitted into the concave portion. An upper urging body, a locking body disposed on the upper urging body, urged upward by the upper urging body and pressed against the lower surface of the motor leg, and a motor corresponding to the recess. It is characterized by combining a plurality of locking portions provided on the leg.

Here, for example, a compression coil spring is used as the upper urging member. Further, as the locking body, for example, a steel ball for a bearing is used.

Thus, in this oscillating device, the locking member is pressed against the locking portion of the motor leg by the upper biasing member fitted into the concave portion of the neck piece upper, so that a resistance to the rotation of the neck piece upper is obtained. That is, transmission of the left and right swinging torque to the motor leg and crispness of the double swinging are obtained. Therefore, it is possible to eliminate the conventional connecting body (the upper part of the neckpiece upper).

(E) Embodiment Hereinafter, the present invention will be described in detail based on one embodiment shown in the drawings. The present invention is not limited by this.

1 to 3, the oscillating device D is incorporated in an electric fan F. The electric fan F mainly includes a blower fan 1, a fan motor 2 for driving the blower fan 1, and a vertical oscillating motor 3 arranged between the blower fan 1 and the fan motor 2.

The vertical oscillating motor 3 has a bracket 4 with two screws 5.
It is fixed to. The bracket 4 is fixed to the fan motor 2 with three screws 6. Front motor cover 7
Are screwed to the bracket 4 by mounting holes 8.
The bracket 4 and the motor leg 9 are rotatably mounted via bearings 11 by two screws 10 as upper and lower oscillating axes (rotating axes).

The vertical oscillating motor 3 is connected to the disk 12 via the bracket 4.
It is connected to. The disk 12 is connected to the motor leg 9 via a link 13. Disc 12 and link 13
And the link 13 and the motor leg 9 are connected to each other by a lower link set screw 15 via a bearing 16. Thus, the torque of the vertical swing motor 3 is transmitted from the disk 12 to the link 13 to the motor leg 9, and the vertical swing is performed.

The oscillating device D is provided with a neck piece 17 for supporting a fan main body as a oscillating device main body, a left and right oscillating motor 18 provided in the neck piece 17, and provided in the fan main body,
The front shape is substantially U-shaped, and includes a motor leg 9 that supports the up / down oscillating motor 3 and a spindle 22 provided on the motor leg 9 so as to protrude downward. The rotation of the left and right oscillating motor 18 is transmitted to the disk 19, the link 20, and the neck piece upper 21.

The spindle 22 is fixed by caulking to the motor leg 9 and inserted into the neck piece upper 21 (the upper end surface of which is in contact with the lower surface of the horizontal portion of the motor leg 9). Therefore, the neck piece upper 21 and the motor leg 9 are in a state where they can rotate with each other. In the horizontal portion of the motor leg 9, holes 37 are provided on the same circumference as five locking portions. On the other hand, a hole is formed on the upper side of the neckpiece upper 21.
One cylindrical concave portion 21a is provided corresponding to 37. The compression coil spring 3 as an upper urging member is provided in the concave portion 21a.
5 is fitted, and a steel ball 36 as a locking body is arranged on the compression coil spring 35.

Thus, the neck piece upper 21 and the spindle 22 rotate due to the action of the hole 37, the compression coil spring 35, and the steel ball 36, judging crispness (double swing).

The compression coil spring 35 presses the neck piece upper 21 and the spindle 22 partially into a press-fit state, applies an appropriate brake to the rotation of both, and suppresses rattling.
The engagement claws 27 include a motor leg 9, a spindle 22, a steel ball 36,
Compression coil spring 35, spring 26 and neckpiece upper
This is to prevent the steel ball 36 and the compression coil spring 35 from falling off when the 21 is assembled.

Reference numeral 28 denotes a left and right swing motor mounting screw, 29 denotes a reinforcing plate, 30 denotes a neck piece cover, 31 denotes a bearing, 32 denotes a spindle retaining screw, and 33 denotes a fan motor shaft. Numeral 34 denotes a rear motor cover, numeral 38 denotes an arc-shaped long hole with which the engaging claw is engaged, numeral 39 denotes an elastic claw for fixing the neck piece cover 30, and numeral 40 denotes a washer arranged on the upper end of the bearing 31.

As described above, since the steel ball 36 is pressed against the hole 37 of the motor leg 9 by the compression coil spring 35 fitted in the concave portion 21a of the neck piece upper 21, A resistance to rotation is obtained. That is, transmission of the left and right swinging torque to the motor leg 9 and crispness of the double swinging are obtained.

Therefore, since the swinging device D can eliminate the conventional connecting body (the upper part of the neckpiece upper), the number of components can be reduced as compared with the conventional one, and the cost is low. In addition, the assembly workability is excellent.

(F) Effect of the Invention Since the present invention is configured as described above, the number of parts can be reduced as compared with the conventional one, the cost is low, and the assembling workability is excellent.
