Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a massager in which a massager body is attached to the backrest of a chair so as to be movable up and down.

A conventional example of this type of massager is shown in FIG.

A plurality of cushion bodies 5 are provided on the front of the backrest portion 2 of the chair 1.
The massager main body 3 is configured to be able to move up and down along the backrest 2 of the chair 1 by rearranging the massager body 3 vertically, so that massage treatment can be performed on the area from the waist to the shoulders. Since the attachment angle between the part 2 and the massager body 3 is constant, if the massager body 3 is attached so that it extends from the rear of the waist, even when treating the shoulder, it can only be used from the rear of the shoulder. There was a drawback that it was not possible to perform massage from the upper part, which is effective for treating the shoulders, and it was not possible to effectively treat the area from the waist to the shoulders.

For this purpose, some massager bodies 3 for layer thickness are provided separately, but in this case, massage can be performed in two areas at the same time: the shoulders and the hips, but it is not possible to This inevitably results in a more complicated structure, increased weight, and increased cost.

The present invention has been made in view of these points, and its purpose is to efficiently perform massage from the shoulders to the waist using a single massage device body, and to develop a massage device body for this purpose. To provide a massager whose orientation is automatically adjusted.

The present invention will be described in detail below based on illustrated embodiments.

Figures 1 to 5 show an embodiment of the present invention, and 2 in the figure shows two back vibros installed in parallel on the back of the chair 1, and a cushion installed on the front side of both back vibros. This backrest part 2 is made up of a body 5 and a body 5.
The massager body 3 is attached to the back vibro so that it can slide up and down.

The massager main body 3 is composed of a movable plate 8 having a massage part 7 and a sliding plate 9 that slides up and down along the back vibro, and the movable plate 8 is rotatable with respect to the sliding plate 9). The movable plate 8 and the sliding plate 9 are connected by a support shaft 10 so that the movable plate 8 and the sliding plate 9 are connected.

A motor 11 is installed on the back of the movable plate 8, and transmits power from one pulley 12 to the massager section 7, and from the other pulley 13 via a clutch 14 to a gear box 15.
The worm shaft (not shown) in the gear box 15 is also driven.

A worm wheel (not shown) that engages with the worm shaft rotates the support shaft 10.

A winding drum 16 is attached to each end of the support shaft 10, and a wire 17 whose upper and lower ends are connected to the upper and lower ends of the back vibro, respectively, is wound around the winding drum 16, and as the winding drum 16 rotates, the wire 17 is wound up on one side (taken off on the other side) so that the movable plate 8 can be moved up and down along the back vibro.

18 is a guide pulley.

The above motor 11, pulley 12゜13, clutch 14,
Gear box 15, winding drum 16, wire 17,
One drive device 4 is composed of a worm shaft, a worm wheel, etc.

A locking arm 19 is provided on the back surface of the movable plate 8 in an arc shape centered on the support shaft 10, and is adapted to engage with an engagement pin 20 provided on the sliding plate 9.

This engagement pin 20 is provided in the bank vibro so that it engages with the locking arm 19 when the massager body 3 moves upward and reaches its limit of upward movement, that is, when the massager part 7 reaches the shoulder position. It is removed using a cam, etc.

Further, the clutch 14 of the drive device 4 can transmit or interrupt the rotation of the motor 11 to the spindle 10 manually or by means such as a solenoid.

Thus, with the clutch 14 engaged, the drive device 4
When the switch is turned on, motor 1 changes from the state shown in Figure 5a.
1 rotates, the winding drum 16 moves upward while winding up the wire 17, and the massager body 3 moves upward.

When the massager main body 3 reaches the shoulder position, the upward movement of the sliding plate 9 is prevented and the engagement pin 20 is removed, so that the movable plate 8 becomes free from rotation.

In this state, the clutch 14 is still engaged and the motor 1 is
When the movable plate 8 is rotated, the winding force of the wire 17 of the winding drum 16 generates a rotational moment about the support shaft 10, so that the movable plate 8 tilts forward as shown in FIGS. 2 and 4. It will rotate.

Therefore, the massager part 7 will be placed on the shoulder from above as shown in FIG.

If the clutch 14 is disengaged at this point, the worm shaft and worm wheel in the gear box 15 will no longer be able to rotate due to cell block action, and the movable plate 8 will be fixed.

Next, when the winding drum 16 is reversely rotated and the clutch 14 is engaged, the massager main body 3 changes from the state shown in FIG. 2 to the state shown in FIG. 2A, and moves downward.

As described above, in the present invention, it is possible to perform massage from the waist to the shoulders by vertically moving the massager body, and since the massager body is tilted forward in relation to the shoulders, it is possible to perform massage from the waist to the shoulders. It is a device that allows you to perform massage that is very effective, and what's more, when you move the massager body up to a position that corresponds to your shoulders, the massager body automatically tilts forward and moves from your waist to your shoulders. Even though the massage is performed using a single massage device, it is always possible to obtain highly effective massage and is easy to operate.
