Description

Massage Apparatus {Massage Apparatus}

The present invention relates to a massage device.

Modern people work 1/3 of the time or more. When working, most people maintain a rigid posture or change in posture very insignificantly, so blood circulation is not good and certain muscles are prone to aggregation. Getting adequate rest is important for good health. However, in addition to simply taking a break, if you do enough stretching to relax your muscles and improve blood circulation, or if exercise is not performed in parallel, fatigue tends to accumulate and blood circulation is poor.

In order to reduce the fatigue of modern people, many massage devices such as a foot massage device or a massage chair are being developed. Massage is one of the medical auxiliary therapies that help blood circulation and relieve fatigue by sweeping, squeezing, pressing, pulling, tapping, or moving the body with hands or special devices. A device for performing a massage by a mechanical device is called a massage device, and various mechanical elements are used for the massage device for an effective massage.

Among these massage devices, a chair-shaped massage device allows a user to sit and receive a massage.

The massage device in the shape of a chair has a coupling relationship or is constrained to each other so that the part supporting the back and the part supporting the buttocks can rotate together, so that the posture of the massage device can be changed through a single driving unit such as an actuator. Accordingly, the user can receive a massage in a more comfortable position than simply sitting in a chair.

However, since the part supporting the buttocks and the part supporting the back are combined, and the rotation angle of the part for massaging the leg is limited, it is difficult for the user to take a supine position or a supine position. That is, one It is difficult to implement both the operation to have the shape of a chair and the operation to have the shape of a bed as a massage device of

In addition, the terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to intentions or customs of users and operators. Therefore, the definition should be made based on the content throughout this specification. The terminology used in the detailed description is for the purpose of describing embodiments of the present invention only, and should in no way be limiting. Unless explicitly used otherwise, expressions in the singular include the meaning of the plural. In this description, expressions such as “comprising” or “comprising” are intended to indicate certain features, numbers, steps, acts, elements, some or a combination thereof, one or more other than those described. It should not be construed to exclude the presence or possibility of other features, numbers, steps, acts, elements, or any part or combination thereof.

In addition, in describing the components of the embodiment of the present invention, terms such as first, second, A, B, (a), (b), etc. may be used. These terms are only for distinguishing the components from other components, and the essence, order, or order of the components are not limited by the terms.

1 is a perspective view of a massage device according to the present embodiment. The massage device 100 according to the present embodiment may include a first seating part 4 , a second seating part 5 , and a third seating part 6 .

Prior to the description, the term “hip” as used herein will be described. The part of the body corresponding to the buttocks is subdivided into the lower part of the buttocks (or buttocks), the hips corresponding to the upper part of the buttocks, the buttocks and the buttocks including the buttocks, and the like, and are called variously.

However, it may not be uniformly differentiated according to each name, and it may be difficult to generalize and explain it because it is difficult to clearly distinguish between the names due to individual differences. Therefore, in the present specification, the entire buttocks are expressed using the terms "hip" or "buttocks", and the above-mentioned separate names are expressed using expressions such as the lower side or upper side of the buttocks.

Therefore, due to the term "hip" as used herein, it should not be construed as being limited to the dictionary meaning of "hip", and includes the user's entire buttocks or, in some cases, the entire buttocks, and a term that includes body parts adjacent to the buttocks to be clearly interpreted as

The first seating part 4 may be a part on which the user's buttocks are seated. However, not only the hip part is seated on the first seat part 4 , but the thigh part including at least a part of the hip part may be seated on the first seat part 4 . That is, the first seating part 4 may correspond to a part on which the user sits among the massage apparatus 100 according to the present embodiment, and may be one of the parts supporting the user's body.

An operating principle of the first seating part 4 will be described later.

The second seating part 5 may be a part on which the user's upper body is seated. However, this does not mean that the second seating part 5 only seats the user's upper body, and the upper side of the user's body part on which the first seating part 4 is seated may be seated on the second seating part 5 . . Therefore, the second seating part 5 can seat the upper body including the upper part of the buttocks.

For example, although it may vary depending on the shape of the backrest of the chair, in general, when the user sits on the chair, the upper side of the user's waist and hips may be supported by the backrest of the chair.

That is, the upper body including at least a part of the buttocks may be seated and supported in the second seating part 5 and supporting the lower side of the buttocks in the first seating part 4 . However, the present invention is not limited thereto, and depending on the shape of the second seating part 5 , only the user's waist may be supported, and not only the waist part but also the neck part or the head part may be seated and supported.

The third seating part 6 may be a part on which the lower body of the user is seated. In detail, the third seating part 6 may be a part on which the lower body below the knee of the user is seated. Accordingly, the third seating part 6 may be a part on which the lower body including the user's feet and calves is seated. Although the body part to be seated on the third seat 6 is not limited to the user's feet and calves, it may be preferable that the portion below the knee be seated on the third seat 6 in consideration of the sitting posture.

A space may be formed in the third seating part 6 into which a portion of the user's body below the knee can be inserted. The space may be formed by opening the front of the third seating part 6, and closing the front of the third seating part 6 so that the user's foot is inserted from the top to the bottom of the third seating part 6 may be formed. When the front side of the third seating part 6 is open, the user's lower body can be easily seated. There may be advantages to Hereinafter, a space formed in the third seating part 6 and into which a portion of the user's body below the knee is inserted will be defined as the seating groove 6a.

The body size varies from person to person. Therefore, the length of the third seating part 6 can be adjusted so that the user has a comfortable sitting feeling even if the length of the part to be seated on the third seating part 6 is different.

The first seating part 4 , the second seating part 5 , and the third seating part 6 may support the user's body, respectively. Each seating unit may serve to not only support the body but also to massage each body part. In order to perform a massage, each seating unit may be provided with a massage unit M for performing a massage.

The massage unit includes a first massage unit (M1) capable of massaging a body located below the user's buttocks and a second massage unit (M2) capable of massaging a body located above the user's buttocks based on the user's buttocks. may include As described above, in order to massage the upper and lower sides of the user's buttocks, the first massage part M1 is provided in the first seating part 4 , and the second massage part M2 is provided in the second seating part 5 . do.

2 is a view of the operation mode of the massage device according to the present embodiment.

With reference to FIG. 2 , before explaining the operation mode of the massage device 100 , FIG. 2 shows a first seating part 4 , a second seating part 5 , a third seating part 6 and a base to be described later. (1, 2) is shown in the form of a frame or simply illustrated.

The massage device 100 according to this embodiment is connected to a first shaft 32 to which the first seating part 4 is rotatably connected and the first shaft 32 to support the first shaft 32 . It may include a support member (31).

The first shaft 32 may be a rotation shaft of the first seating part 4 . The axis of rotation of the first seating part 4 does not mean that it must always rotate integrally with the first shaft 32 , but may mean that it rotates around the position of the first shaft 32 as an axis.

In addition, the support member 31 may serve to support the load of the massage device 100 by supporting the first shaft 32 .

Hereinafter, operable modes of the massage device 100 according to the present embodiment will be described with reference to FIG. 2 .

Figure 2 (a) is a view showing a first mode in which a separate operation is not made, Figure 2 (b) is a view showing a second mode in which the load applied to the user's waist can be relieved, Figure 2 (c) is a diagram illustrating a third mode in which the user can lie down.

2(a) shows a first mode (or base mode) in which a separate operation is not performed. The shape shown in Fig. 2 (a) may be a shape when the massage device 100 according to the present embodiment is de-energized. However, even if the massage device 100 is energized, the shape may not be changed immediately or the mode may not be changed. That is, an operation of massaging the body may be performed even in the first mode.

In addition, when de-energized, the second seating part 5 and the first seating part 4 may be formed closer to a right angle. This is because, in general, when installing the massage device 100 , since it is installed in a non-energized state, it is desirable to minimize the volume occupied by the massage device 100 . Therefore, the first mode does not necessarily indicate the position of each seating part when non-energized, and may mean an energized mode in which massage is performed as described above.

Hereinafter, in describing the angle and the rotation direction, a position or an operating direction will be described by setting an imaginary axis.

In detail, the virtual axis in the longitudinal direction of the massage device 100 among the directions horizontal to the ground is the x-axis, and the x-axis is perpendicular to the x-axis in the direction horizontal to the ground, and the virtual axis in the width direction of the massage device 100 is defined as the x-axis. As the y-axis, an imaginary axis perpendicular to both the x-axis and the y-axis is set as the z-axis. In this case, the x-axis, y-axis, and z-axis may be virtual axes set to pass through the first shaft 32 .

In addition, in the x-axis, the direction to the side where the third seating part 6 is located based on the center of the massage device 100 is “front”, “front side”, “front of the massage device” or “front of the massage device”. It will be described using terms pointing to the front, such as "side", and the direction to the side where the second seating part 5 is located based on the center of the massage device 100 is "back", "rear", etc. to explain

In addition, one side of the parts partitioned based on the y-axis and the z-axis may be described with terms such as "left side of the massage chair" or "left side", and the other side of the parts partitioned based on the y-axis and z-axis is It may be described in terms such as “right of the massage chair” or “right”.

In addition, in the z-axis, the direction of the ground is explained using terms that indicate a downward direction such as “down” and “downward”, and the direction toward the sky or the ceiling is described using terms indicating an upward direction such as “up” and “upward”. to explain

In addition, in explaining the angle, it will be described with reference to the paper of the above-mentioned "in front of the massage device". However, the angle is not necessarily described with reference to the ground in front of the massage device, and the standard for describing the angle may vary as needed. For example, "A is positioned to form 10 degrees with the ground." Or the expression "A is positioned to form 10 degrees with the x-axis" means that A is positioned so that the angle A forms with the ground in front of the massage device is 10 degrees, and the reference point is explicitly presented. In this case, the ground in front of the massage chair is not the standard, but the suggested reference point is the standard for explaining the angle. Furthermore, the angle in the present specification may mean the angle of the part on which the user's body is seated.

In the first mode, the first seating part 4 may form a first angle A with respect to the ground. The first angle A may satisfy a range of greater than 0 degrees and less than or equal to 15 degrees. Preferably, the first seating portion 4 may form about 10 degrees with the ground. However, it should not be construed as being limited to the above-described range of angles.

By forming the first angle A, when the user sits on the massage device, the user's body can be naturally seated between the first seating part 4 and the second seating part 5 . It can also serve to reduce the burden on the calf and feet below the knee by lifting the thigh.

In the first mode, the second seating portion 5 may be positioned to form an obtuse angle with respect to the first seating portion 4 . That is, the second seating part 5 may be positioned to form an obtuse angle with respect to the ground, and to have an angle forming an obtuse angle with respect to the first seating part 4 as well. That is, the second seating part 5 may have a shape inclined to the rear of the massage device 100 .

The second seating part 5 may be positioned to form an angle of about 116 degrees to 120 degrees with respect to the first seating part 4 . Preferably it can be tilted about 118 degrees. However, the angle range for the first seating part 4 and the second seating part 5 is one embodiment, and is not limited to the above-described angle range.

When the second seating part 5 is positioned to form an obtuse angle with respect to the first seating part 4 , the user can easily lean the upper body against the second seating part 5 . In addition, when the second seating part 5 is inclined, the weight of the user can be better supported than when the second seating part 5 is positioned at a right angle to the ground. In addition, as the second seating part 5 is inclined, the user's sitting feeling may increase.

Figure 2 (b) is a view showing a second mode in which the load applied to the user's waist side of the massage device according to the present embodiment can be relieved. The second mode may be a mode in which the first seating part 4 and the second seating part 5 have a specific angle, and the weight is evenly distributed to support the user's body and to give the user a comfortable feeling as if he/she receives less gravity. have.

In addition, it may be a mode capable of minimizing the pressure applied to joints such as knees as well as the user's waist. Accordingly, since the waist or joint is a part that supports the body during daily life, it is possible to reduce the burden on the waist or joints by using the massage device 100 according to the present embodiment, thereby providing comfort to the user.

In addition, the user's body is more closely attached to the massage device 100, so that the massage effect by the operation of the massage unit may increase. In addition, when the heart is operated to be located lower than the lower body side, it can also exert a positive effect on blood circulation to relieve swelling of the body.

In the second mode, the first seating part 4 may be rotated using the first shaft 32 as a rotation axis. In the second mode, the first seating portion 4 may be positioned to rise higher than the first angle A to form a second angle B with the ground. The second angle B may be a greater angle than the first angle A. The second angle B may be an angle having a range of greater than 15 degrees and less than or equal to 25 degrees with the ground. Preferably, the second angle B may be an angle forming about 20 degrees with the ground. However, it is not limited to this angle range.

Even in the second mode, the second seating portion 5 may be positioned to form an obtuse angle with respect to the first seating portion 4 . That is, when the massage apparatus 100 according to the present embodiment is switched from the first mode to the second mode, the second seating part 5 may be rotated using the support member 31 as a rotation axis.

The second seating part 5 may be positioned to have a range of 120 degrees to 136 degrees with respect to the first seating part 4 . Preferably, the second seating part 5 may be positioned to have an angle of about 123 degrees with the first seating part 4 . However, the above-described range of angles is only an example and is not interpreted as being limited to the above-described range of angles.

The second mode of the massage device 100 may mean a mode in which a body load is appropriately distributed. Therefore, the angle formed by the first seating portion 4 with the ground and the angle formed by the second seating portion 5 with the first seating portion 4 are not clearly defined, and may be performed in several steps depending on the degree of the angle. It may be formed separately. For example, the second mode may be divided into several modes within the second mode, such as the 2-1 mode and the 2-2 mode, and the angle may be appropriately adjusted according to the user's request.

Figure 2 (c) is a view showing a third mode (or 180 degrees reclining mode) in which the first seating part 4 and the second seating part 5 form 180 degrees.

In order to become the third mode, it is preferable that the first seating part 4 and the second seating part 5 are formed to be able to rotate separately. When the first seating part 4 and the second seating part 5 are formed to restrain each other in order to maintain the shape of the chair, one actuator ) has the advantage of being able to change the mode by using a driving source, such as, but it may be difficult to implement the third mode as shown in the present embodiment.

The rotation of the first seating part 4 and the second seating part 5 may mean rotation from the x-axis to the z-axis or from the z-axis to the x-axis. That is, the first seating part 4 and the second seating part 5 may be rotated using the support member 31 as a rotation axis.

For example, when the first seating part 4 is positioned to form a first angle A with the ground in the first mode and is switched to the second mode, in the x-axis to form a second angle B with the ground. It can be rotated towards the z-axis.

Conversely, when the first seating part 4 is switched from the second mode to the first mode, it is positioned to form a second angle B and rotates from the z-axis to the x-axis to form a first angle A with the ground. can be

In addition, when the second seating part 5 is positioned to form an obtuse angle with the first seating part 4 in the first mode and is switched to the second mode, it rotates from the z-axis to the x-axis so as to be more inclined to the rear of the massage device. can be Conversely, when the second seating part 5 is switched from the second mode to the first mode, it may be rotated from the x-axis to the z-axis.

Accordingly, the rotation of the first seating part 4 and the second seating part 5 separately or independently means that the rotation of the first seating part 4 does not affect the rotation of the second seating part 5 . not, it may mean that the rotation of the second seating part 5 does not affect the rotation of the first seating part 4 .

That is, the rotation of both the first seating part 4 and the second seating part 5 as the mode is changed means that the seating parts are operated separately to implement each mode. Therefore, the rotation of any one of the first and second seating parts 4 and 5 does not affect the rotation of the other one of the first and second seating parts 4 and 5. Neither one rotation is performed in dependence on another rotation.

In order for the first seating part 4 and the second seating part 5 to rotate independently of each other, there is not necessarily a fastening relationship between the first seating part 4 and the second seating part 5 . However, when the first seating part 4 and the second seating part 5 are independently rotatable, there may be no difficulty when the massage device 100 is operated while switching the first mode, the second mode and the third mode. have. The angle formed by the first seating part 4 and the second seating part 5 does not need to be exactly 180 degrees, and an angle close to 180 degrees may be formed within an error range.

Of course, the massage apparatus 100 according to the present embodiment does not simply change the posture in the three modes described above, and massage can be performed in each mode.

3 is a view showing the twisting operation of the massage device according to the present embodiment. Hereinafter, it will be described with reference to FIG. 3 .

When the massage device 100 is in the third mode, the massage device 100 may be capable of twisting operation. As used herein, "twist" or "twisting" means that the first seating part 4 or the second seating part 5 rotates in a rotation direction perpendicular to the rotation direction when changing the above-described three modes. it could mean

“Twist” or “twisting” may mean that the second seating part 5 is rotated to be inclined alternately to the left and right sides of the massage device 100 . When one side of the second seating part 5 is rotated from the y-axis to the z-axis direction, the other side of the second seating part 5 is rotated from the z-axis direction to the y-axis direction, and one side of the second seating part 5 is rotated from the z-axis direction to the y-axis direction. When the z-axis is rotated in the y-axis direction, the other side of the second seating part 5 may be rotated in the z-axis direction in the y-axis. That is, it means that both sides of the second seating part 5 are rotated to be inclined alternately with each other.

When the massage device 100 is capable of twisting, the user may be stretched by twisting the upper body left and right when using the massage device 100 . Therefore, the massage device 100 according to this embodiment can perform a massage by a massage machine, and stretching can also be performed by twisting the second seating part 5, so that a massage effect superior to conventional massage devices can be obtained. can perform

4 is a view showing a stretching operation of the massage device according to the present embodiment.

The stretching operation of the massage device 100 according to the present embodiment may be an operation capable of stretching the body toward the ground based on the user's waist. In the present specification, the stretching operation does not exclude the stretching effect of the twisting operation or stretching the user's body only by the method to be described later, and may be a word selected for a concise and clear description of the invention.

Hereinafter, it will be described with reference to FIG. 4 .

The second base 2 may include a frame forming a frame of the second base and an actuating connection. The frame of the second base may be connected to the frame of the first base so that the second base 2 and the first base 1 may be connected. And as the frame of the second base slides, the second base 2 may slide on the first base 1 .

The degree of rotation of the first seating part 4 and the second seating part 5 according to the sliding distance and the sliding distance of the second base 2 on the first base 1 varies according to the intention of the user or the manufacturer. can be set to

For example, the first operation part 42 may be provided on the first seating part 4 , and the second operation part 52 may be provided on the second seating part 5 . In this case, the degree to which the first seating part 4 is rotated according to the sliding distance of the second base 2 with respect to the first base 1 may be determined by electronic control of the first operating part 42 . . Similarly, the degree to which the second seating part 5 is rotated may be determined by electronic control of the second operation part 52 .

On the other hand, when only the second seating part 4 is provided with an electronically operated driving part, the first seating part 4 is dependent on the sliding distance of the second base 2 through a configuration such as a link (not shown). The first seating part 4 may be rotated.

That is, the degree of rotation of the first seating part 4 and the second seating part 5 according to the sliding of the second base 2 may vary, and accordingly, the operation method of the massage device 100 may be changed.

The operation connection part may be a part to which the second operation part 52 is connected. The second operation part is a part that rotates the second seating part 5 . The angle of the first seating part 4 may be adjusted by rotation of the link according to the sliding of the second base 2 or the angle may be adjusted by the first operation part 42 .

The wheel w is in contact with the first base 1 and serves to reduce friction that may occur between the first base 1 and the second base 2 when the second base 2 slides. can

Since the wheel w may be provided in the form of a wheel, the sliding of the second base 2 may be aided, and the first base 1 and the second base 2 may be slid while the second base 2 is slid. It is possible to reduce noise that may be generated between the two bases 2 and to minimize wear of the first frame and the second frame.

In more detail, when the first frame and the second frame directly contact to perform sliding, noise may become severe due to the load applied to the second base 2 . In addition, the second base 2 and the first base 1 are in close contact with each other by the load transmitted to the second base 2 , so it may be difficult to smoothly slide.

Therefore, the wheel (w) is provided on the lower side of the second frame to assist the role of the support of the second base (2), it is possible to make the sliding of the second base (2) smoothly. Furthermore, the wheel w may be symmetrically provided on the lower side of the second frame.
