[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath massager used while immersed in a bathtub.

[0002]

2. Description of the Related Art With respect to a bath massager according to the present invention, it is necessary to reduce the speed by a worm shaft and a pair of worm gears meshing with the worm shaft, and to attach a massage ball to a support shaft of the worm gear via a tilting rotating shaft.
It is known from Japanese Utility Model Publication No. 61-15878. further,
An application in which this type of massage device is changed in specification for bathing has been filed (Japanese Utility Model Application No. 2-110033). In this case, a motor, a speed reduction mechanism and a massage ball are accommodated in a flat cylindrical outer case, and the case opening is closed in a watertight manner with a rubber plate. The massage ball protrudes outward from the opening surface of the case, and transmits the turning motion to the human body via the rubber plate.

[0003]

As described above, in the form in which the motor and the speed reduction mechanism are accommodated in the sealed outer case, when the massager is used in a state immersed in bath water, the buoyancy of the case is reduced. The whole is going to come up. In many cases, the outer case is formed sufficiently larger than the space occupied by the motor and the speed reduction mechanism in consideration of design requirements and convenience in handling, and the amount of drainage is not small. Therefore, when the massager is used by hand, it must overcome the buoyancy to maintain the immersion state, and it is difficult to handle the immersion state.

If the weight that overcomes buoyancy is attached to the outer case, the above-mentioned problem can be solved. However, in this case, it is inevitable that the massaging device is weighted when handling outside the bathtub or when transporting goods. The purpose of this invention is to improve the case structure so that the buoyancy acting on the massage device can be suppressed without increasing the weight, thereby improving the immersion state and the ease of handling outside the bathtub, and its usability. Is to improve.

[0005]

In the massage device of the present invention, a motor 2 and a speed reduction mechanism 3 are housed in a hollow outer case 1, and a plurality of output shafts 4 provided in the speed reduction mechanism 3 are used. It is assumed that the massage ball 6 protruding from the outer surface of the outer case 1 is driven to turn via the tilting turning shaft 5. The outer case 1 is an inner peripheral wall 15 provided in the case, and the inner machine room 16 and the outer space That the motor 2 and the speed reduction mechanism 3 are housed inside the machine room 16, and that the opening of the inner peripheral wall 15 is sealed in a watertight manner by a seal body 23. A requirement is that a through hole 26 communicating the vacant space 17 with the space outside the case is formed in the face wall of the exterior case 1 facing the case 17. More specifically,
Shell-shaped front case 1a and rear case 1 divided into front and rear
b, the outer case 1 is formed, and the front case 1
A ball window 14 for exposing the massage ball 6 to the outside of the case is opened in the face wall of the ball window 1a.
It is required that the protective cover 20 is attached to the case 4 from the inner side of the case and that the seal body 23 is formed integrally with the peripheral edge of the protective cover 20.

[0006]

In the interior space of the outer case 1, a portion other than the machine room 16 accommodating the motor 2, the speed reduction mechanism 3, and the like, that is, the vacant space 17 serving as a surplus space communicates with the outside through the opening 26. I have. Therefore, when the entire massage device is immersed in bath water, the empty room 17 is filled with the bath water that has entered through the opening 26, and the amount of drainage can be reduced by the amount of the filled bath water. Buoyancy can be suppressed. Further, outside the bathtub, the water in the empty room 17 is discharged through the opening 26, so that the water does not drop.

[0007]

According to the present invention, a required number of compartments 16 for accommodating the motor 2 and the speed reduction mechanism 3 are defined inside the outer case 1, and only the compartments 16 are sealed with the seal 23. The vacant rooms 17 other than the machine room 16 can freely enter and leave the bath water through the passage 26. Thus, in a state where the massage device is immersed in the bathtub, the empty room 17 is filled with bath water, so that the amount of drainage of the outer case 1 can be reduced by that amount, and buoyancy acting on the massage device can be suppressed. In addition, by discharging the water in the empty space 17 outside the bathtub, the weight of the massager can be prevented from increasing, and the massager can be easily handled in the immersion state and outside the bathtub as a whole.

[0008]

And rotatably supported by the gear box 9. As shown in FIG. 3, the inclined turning shaft 5 is mounted obliquely with respect to the output shaft 4, and supports the massage ball 6 via a ball joint 12 at the tip. The left and right output shafts 4 are rotationally driven in opposite directions. When the output shaft 4 rotates, the center of the ball joint 12 makes a circular motion around the output shaft 4, and the massage ball 6 moves along with the circular motion, so that a massage operation is obtained.

The outer case 1 is formed by joining a shell-shaped front case 1a and a rear case 1b, which are divided into front and rear portions, in a lid-to-cover shape. On the front wall of the front case 1a, a ball window 14 for exposing the massage ball 6 to the outside of the case is provided.
It is opened in a long oval shape on the left and right (see FIG. 4). An inner peripheral wall 15 is provided on the inner surface of the outer case 1 so as to include the ball window 14 inside, thereby dividing the inside of the outer case 1 into an inner machine room 16 and an outer vacant room 17. Inner wall 1
5 is formed integrally with the rear case 1b,
In cooperation with a U-shaped groove 19 provided on the inner surface of a, a seal body 23 described later is sandwiched and fixed. Motor 2 and reduction mechanism 3
Is accommodated in the machine room 16. In other words, only the space required to accommodate the motor 2 and the speed reduction mechanism 3 is defined by the inner peripheral wall 15. The front and rear cases 1a and 1b are fastened by a number of screws 21 provided along the joint peripheral wall.

A protective cover 20 is attached to the ball window 14 in order to close the ball window 14 and to prevent the towel or the like from being entangled in the massage ball 6. The cabin 16 is hermetically sealed by the protective cover 20, the inner peripheral wall 15, and the opposing walls of the front and rear cases 1a and 1b. The protective cover 20 is a rubber molded product made of silicon rubber, and has a main cover portion 22 bulging outward from the ball window 14 near the upper portion thereof.
And the seal body 23 is integrally provided along the periphery. The protective cover 20 is attached to the front case 1a from the inner side of the case, and circumscribes the massage ball 6 in a state where the main cover portion 22 is elastically deformed as shown in FIG. FIG.
As shown in the figure, the seal body 23 has a U-shaped groove 23a.
And the bead 23b at the outer edge of the groove are integrally formed, and the groove 23a is sandwiched and fixed between the groove 19 and the inner peripheral wall 15 in the front-rear direction. Separately from the seal body 23, a hook portion 24 is provided along the lower half peripheral surface of the ball window 14, and this is engaged with a hook rib 25 provided on the inner surface of the opening of the ball window 14 (see FIG. 1). .
This is to prevent the lower half peripheral edge of the main cover portion 22 from moving when the massage ball 6 operates.

In order to facilitate the handling of the massager in a state of being immersed in the bathtub, a plurality of openings 26 are opened near the upper and lower ends of the rear wall of the empty room 17 as shown in FIG. Water is allowed to enter the vacant room 17 through the passage 26. The upper port 26 helps to evacuate the internal air when bath water fills the vacant room 17, further reducing the time required for drainage.

The massage device is installed in the bathtub T via a mounting frame 29 having a ladder structure shown in FIG. This mounting frame 29
A plurality of horizontal rails 31 are fixed between a pair of side frames 30, and suction cups 32.
Attach 32. A hook 33 is provided on the rear surface of the outer case 1. By hooking the hook 33 on an arbitrary cross bar 31, a part or the whole of the massager is immersed in bath water to be used in place. it can. Although not shown, the massager is connected to a control box installed outside the bathroom via a power cord.

According to the massager constructed as described above, the vacant room 17 is filled with the bath water that has entered through the opening 26 in the immersion state. The acting buoyancy is reduced, and the handling in bath water, especially when performing massage in a hand-held state, can be facilitated. Further, in a state where the massager is taken out of the bathtub, the water in the empty room 17 is discharged from the opening 26, so that the massager does not weight. Since the protective cover 20 is formed of silicon rubber having high elasticity, the main cover portion 22 can be elastically deformed following the turning operation of the massage ball 6. This means that the operation of the massage ball 6 can be reliably transmitted to the human body, and furthermore, the resistance generated when the ball is driven can be reduced as compared with the case where the massage ball 6 and the main cover portion 22 slide relatively. Also. The flexible protective cover 20 helps soften the tactile sensation when the human body comes into contact, and also helps the massage ball 6 to be formed only of a hard plastic material.

FIG. 7 shows another embodiment of the present invention in which the protective cover 20 is changed. In this case, a hemispherical contact ball portion 35 that fits outside the massage ball 6 is formed on the main cover portion 22, and a large number of circular protrusions 36 for obtaining an acupressure effect are provided on the outer surface thereof. The thickness of the contact ball portion 35 is set to be thicker than other portions. Thus, the circular protrusion 36 is provided on the main cover portion 20.
Is provided, the contact friction pressure on the inner surface of the contact ball portion 35 is reduced as compared with the case where a similar protrusion is provided on the massage ball 6, and the contact ball portion 35 can be prevented from being quickly deteriorated and damaged. Further, since the circular protrusion 36 itself is prevented from turning, the circular protrusion 36 can be pressed against the body in a point contact manner, so that the massage effect is improved.

FIG. 8 shows still another embodiment of the present invention in which the structure of the machine room 16 and its sealing structure are changed. In this case, the ball window in the above embodiment is omitted, the output shaft 4 protrudes outward from the front case 1a, and the space between the output shaft 4 and the front case 1a is sealed with an oil seal 37. Further, the inner peripheral wall 15 is provided so as to protrude from the front and rear cases 1a and 1b so as to be opposed to each other. In this case, the seal body 23 is formed as an independent component separate from the protective cover 20.

In addition to the above, it is possible to secure a small gap in a circular shape at the joint between the peripheral walls of the front and rear cases 1a and 1b, and use this as the passage 26. Two or more massage balls 6 may be provided. The vacancies 17 may be provided outside the machine room 16 in a dispersed manner, and need not be formed in an endless annular shape.
