Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a small vibrator that is held in a hand and transmits vibrations to the body.

2. Description of the Related Art Conventionally, there are various types of small-sized vibrators of this type, but a spherical body has a completely spherical outer shape.

Problems to be Solved by the Invention In such a conventional spherical configuration, when placed on a plane,
It had the drawbacks of not rolling and stopping, and of the hands being slippery when attaching or removing batteries or when turning the switch on and off.

The present invention solves these problems and does not roll even when placed on a flat surface.
The purpose is to facilitate FF.

Means for Solving the Problem In order to solve this problem, the present invention provides a concave portion on the spherical outer peripheral surface on the center of gravity line passing through the center of gravity of the spherical body.

Function With this configuration of the concave portion, if the concave portion of the spherical outer peripheral surface is placed on a flat surface, it will be on the center of gravity, so it will not roll naturally, and put your finger on the concave portion and turn the cover off the case to remove the battery inside the case. The switch can be easily turned on and off by putting on and taking off or by locking the cover to the case and then turning your finger by turning it into the recess.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. In the figure, 1 is a fixed plate, and a battery housing portion 2, a plus lead 3, and a minus lead 4 are provided on the front side of the fixed plate 1, and the tips of the plus lead 3 and the minus lead 4 project to the back side of the fixed plate 1. ing. Reference numeral 5 is a motor, and an eccentric weight 6 is press-fitted at the tip of the shaft of the motor 5. 7
Is an elastic member, and the motor 5 is attached to the fixed plate 1 by sandwiching the elastic member 7, and the fixed plate 1 is fastened and fixed to the case 8 with the attaching screw 9. Reference numeral 10 is a motor plus lead pulled out from the motor, and is in contact with the plus lead 3 on the battery housing side. Reference numeral 11 denotes a motor minus lead drawn out from the motor, which faces the minus lead 4 at a constant interval. An elastic piece 12 is attached to the case 8, and the other end is in contact with the shaft end of the motor 5. A battery spring 13 is in contact with the minus lead 4. The other side of the battery spring 13 is the plus lead 3, one end of the plus lead 3 is the receiving side of the battery, and the other end is in contact with the motor plus lead 10 pulled out from the motor 5. 14 is a click sound spring, and a click rib (not shown) provided on the cover 15 side
When it makes contact with the click sound spring 14, the click sound spring 14 swings and makes a clicking sound. Reference numeral 16 is a rib provided on the cover 15.

The case 8 and the cover 15 are engaged with each other by a plurality of locking portions 17 by slightly rotating each other. The rib 16 provided on the cover 15 is a minus lead 4 when the cover 15 is slightly rotated.
Push down and touch the motor minus lead 11. At that time, a similar rib provided at another position of the cover 15 comes into contact with the click sound spring 14 and swings to make a clicking sound.
Reference numeral 18 denotes a concave portion provided in the cover, and 19 denotes a pressing plate which functions to press the battery.

Next, the operation will be described. The cover 15 is slightly rotated to remove the cover 15 from the case 8, and the battery is stored in the battery storage unit 2.
Then, rotate the cover 15 to the case 8 and attach it again.

When it is further turned a little, the rib 16 of the cover 15 comes into contact with the minus lead 4 and the motor minus lead 11 pulled out from the motor 5 housed in the case 8, so that the motor 5 rotates and the eccentric weight 6 press fitted into the motor shaft rotates. And the whole vibrates small. Next, when the cover 15 is rotated slightly in the opposite direction, the rotation of the motor 5 stops and the vibration stops. The recess 18 provided in the cover 15
When you put your finger on the cover 15, the cover 15 and the case 8 are easily rotated, and it is easy to attach / detach the battery or to turn the switch ON / OFF. Further, since the recess 18 is provided on the center of gravity of the spherical body, When placed on a flat surface, it will not roll naturally.

Further, since the elastic piece 12 in the case 8 is elastically brought into contact with the shaft end of the motor 5, the motor 5 is less likely to be damaged by vibration or impact.

As described above, according to the present invention, since the concave portion is provided on the outer peripheral surface on the center of gravity line of the small-sized vibrator having a spherical body, the concave portion does not naturally roll when placed on a flat surface, and the concave portion It is easy to rotate the cover or case by putting your finger on it, which makes it easy to attach and remove the cover and case, and it is also easy to turn the switch on and off.
