1. Field of the Invention
The present invention relates to a massage device, and more particularly to a two dimensional moving massage device.
2. Description of the Prior Art
Today, people are living under great pressure and therefore need to release stress by using some massage devices. Normally, massage devices are provided with massage heads to carry out massage operation by ways of rotation, kneading or up and down movement. However, the conventional massage ways of rotating, kneading or movement might not be able to satisfy the demands of different users. Furthermore, the structure for moving the massage heads should normally be used in combination with guiding rails in such a manner that the massage heads are provided with guiding members, and a drive member drives the massage heads to rotate, so as to make the guiding members move along the rail. It is clear that the rotation of the massage heads cause the displacement of the same. However, such arrangements would restrict the action of massage or displacement.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary object of the present invention is to provide a two dimensional moving massage device which is capable of performing different massage movements so as to meet different users' different demands.
To achieve the above object, a two dimensional moving massage device in accordance with the present invention comprises: a base, a first movable device movably disposed in the base, a second movable device movably disposed in the first movable device, and two massage assemblies disposed on the second movable device.
The base is provided with a toothed bar extending in an up-and-down direction, and a direction perpendicular to the up-and-down direction is defined as a left-and-right direction;
The first movable device is disposed in the base and provided with a first guiding portion extending in the left-and-right direction and a direction restricting groove extending in the up-and-down direction, in the first movable device are provided a first motor, a first stage driven gear and a second stage driven gear. The first stage driven gear is rotated by the first motor, the second stage driven gear is concentric and rotating together with the first stage driven gear, and the second stage driven gear extends out of the first movable device and is engaged with the toothed bar of the lower shell.
The second movable device is received in the first movable device and provided at a bottom thereof with a second guiding groove, and the first guiding portion of the first movable device is slidably inserted in the second guiding groove of the second movable device. In the second movable device are disposed a second motor, a medium gear, and a left-and-right moving driven gear.
The second motor is provided with a rotary shaft.
The medium gear is pivotally disposed on the second movable device and engaged with the second stage drive gear.
The first stage driven gear is pivotally disposed on the second movable device and engaged with the medium gear, the left-and-right moving driven gear is eccentrically provided with a direction restricting pin which extends out of the second movable device and into the direction restricting groove of the first movable device.
The massage assembly includes a massage head mounted on the second movable device and extends out of the first movable device.
The first stage drive gear of the first motor cooperates with the toothed bar of the base to make the first movable device move in the up-and-down direction, the left-and-right moving driven gear is restricted to only be movable in the left-and-right direction and in the up-and-down direction by the first guiding portion and the direction restricting groove. Therefore, rotation of the left-and-right moving driven gear will be converted into displacement of the left-and-right moving driven gear along the left-and-right direction and the up-and-down direction. The massage assembly disposed on the second movable device is also capable of moving both in the up-and-down and left-and-right directions.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

The first movable device 20 is provided at the bottom thereof with a plurality of first guiding grooves 21 extending in the up-and-down direction Y, and the guiding portions 112 of the lower shell 11 are slidably inserted in the first guiding grooves 21 of the first movable device 20. The first movable device 20 is provided with a plurality of first guiding portions 22 extending in the left-and-right direction X and a direction restricting groove 23 extending in the up-and-down direction Y. On the first movable device 20 are further provided a first motor 24, a first stage drive gear 25, a second stage drive gear 26, a first stage driven gear 27 and a second stage driven gear 28. The first motor 24 includes a rotary shaft 241 and is fixed on the lower shell 11. The first stage drive gear 25 is pivotally disposed in the first movable device 20 and engaged with the rotary shaft 241 of the first motor 24. The second stage drive gear 26 is concentrically mounted on and rotates together with the first stage drive gear 25. The first stage driven gear 27 is pivotally disposed on the lower shell 11 and engaged with the second stage drive gear 26. The second stage driven gear 28 is concentric and rotates together with the first stage driven gear 27, and the second stage driven gear 28 extends out of the first movable device 20 and is engaged with the toothed bar 111 of the lower shell 11.
The second movable device 30 is provided at the bottom thereof with a plurality of second guiding grooves 31, and the first guiding portions 22 of the first movable device 20 are slidably inserted in the second guiding grooves 31 of the second movable device 30. In the second movable device 30 are disposed a second motor 32, two first stage drive gears 33, two second stage drive gears 34, two medium gears 35, a first stage driven gear 36, a second stage driven gear 37, and a left-and-right moving driven gear 38.
The second motor 32 is provided with two rotary shafts 321 at two ends thereof.
The two first stage drive gears 33 are pivotally disposed on the second movable device 30 and engaged with the rotary shafts 321 of the second motor 32, respectively.
The second stage drive gears 34 are concentric and rotate together with the first stage drive gears 33.
The medium gears 35 are pivotally disposed on the second movable device 30 and engaged with the second stage drive gears 34, respectively.
The first stage driven gear 36 is pivotally disposed on the second movable device 30 and engaged with one of the two medium gears 35.
The second stage driven gear 37 is concentric and rotates together with the first stage driven gear 36.
The left-and-right moving driven gear 38 is pivotally disposed on the second movable device 30 and engaged with the second stage driven gear 37. The left-and-right moving driven gear 38 is eccentrically provided with a direction restricting pin 381 which extends out of the second movable device 30 and into the direction restricting groove 23 of the first movable device 20.
The two massage assemblies 40 each comprise an oscillating rod 41 and two massage heads 42 at two ends of the oscillating rod 41. The oscillating rod 41 has one end eccentrically fixed to the respective medium gears 35 and another end slidably disposed on the surface of the second movable device 30.
When the first motor 24 is powered on, the rotary shaft 241 rotates the first stage drive gear 25, the first stage drive gear 25 then rotates the second stage drive gear 26, the second stage drive gear 26 then rotates the first stage driven gear 27, then first stage driven gear 27 then rotates the second stage driven gear 28. When the second stage driven gear 28 rotates, it will move linearly along the toothed bar 111 (since the second stage driven gear 28 is engaged on the toothed bar 111) and drive the first movable device 20 to move in the up-and-down direction Y. Meanwhile, the second movable device 30 disposed on the first movable device 20 and the massage assemblies 40 disposed on the second movable device 30 will also be driven to move in the up-and-down direction Y. in this way, the massage assemblies 40 are capable of performing massage by sliding up and down.
Then, if the second motor 32 is also powered on, the rotary shaft 321 rotates the first stage drive gears 33, the first stage drive gears 33 then rotate the second stage drive gears 34, and the second stage drive gears 34 then rotate the medium gears 35. At this moment, the massage assemblies 40 on the medium gears 35 will rotate eccentrically so as to perform massage in the form eccentric rotation.
Meanwhile, one of the medium gears 35 rotates the first stage driven gear 36, the second stage driven gear 37 and the left-and-right moving driven gear 38, in sequence. Since the left-and-right moving driven gear 38 is disposed on the second movable device 30, the second movable device 30 is restricted to only be movable in the left-and-right direction X by the first guiding portions 22, and the left-and-right moving driven gear 38 is restricted to be movable only in the up-and-down direction Y by the direction restricting pin 381 which is restricted in the direction restricting groove 23. Therefore, rotation of the left-and-right moving driven gear 38 will be converted into displacement of the left-and-right moving driven gear 38 along the left-and-right direction X and the up-and-down direction Y. Namely, the direction restricting pin 381 will slide in the up-and-down direction Y along the direction restricting groove 23. The second movable device 30 is restricted to be movable in the left-and-right direction X by the first guiding portion 22. Certainly, the massage assemblies 40 disposed on the second movable device 30 are also capable of moving in the left-and-right direction X.
It is clear from the above description that when the first and second motors 24, 32 are simultaneously powered on, the first movable device 20 will move in the up-and-down direction Y, and the second movable device 30 will move in the left-and-right direction X, so that the massage assemblies 40 can move in the up-and-down direction Y and left-and-right direction X along with the first and second movable devices 20, 30. Besides, the massage assemblies 40 are also capable of performing eccentric rotation. Hence, the massage device of the present invention can perform various massage movements, including two directional movement and eccentric rotation type oscillation, so as to satisfy different users' different requirements. Furthermore, the arrangement of the two-stage gears can reduce the size of the massage device.
While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
