Description

[Technical field]

[0001] The present invention relates to a massage machine. [Background technology]

[0002] Conventionally, a chair-type massage machine has been proposed that uses a bag disposed in the seat to provide massage, and is configured to inflate the bag by selecting a lifting mode to lift the rear portion of the seat relative to the front portion (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 3686130 Summary of the Invention [Problem to be solved by the invention]

[0004] In the chair-type massage machine described in Patent Document 1, the height of the backrest is fixed, so for users with a high seated height, part of the upper body (e.g., shoulders) extends beyond the backrest, making it impossible to massage the entire upper body. The present invention has been made to solve the above-mentioned problems, and has an object to provide a massage machine that can massage the entire upper body even for users who sit at a high height. [Means for solving the problem]

[0005] The present invention is a massage machine having a frame, a seat portion attached to the frame so as to be freely swingable in the vertical direction, a backrest portion attached to the rear of the frame, and a control unit, wherein the backrest portion is provided with a massage mechanism that can be raised and lowered, and the frame is provided with a rocking mechanism for rocking the seat portion in the vertical direction, and the control unit is configured to control the rocking mechanism to rock the seat portion upward when the power of the massage machine is turned OFF, thereby hiding part of the treatment range of the massage mechanism, and to control the rocking mechanism to rock the seat portion downward when the power of the massage machine is turned ON, thereby exposing the treatment range of the massage mechanism that was hidden, so that the upper body of the user can be massaged by the massage mechanism. With this configuration, the seat portion swings downward, so that even a user with a high seated height can have the entire upper body massaged without any part of the upper body being exposed from the backrest portion.

[0006] It is also preferable that the seat portion is attached so as to be able to swing up and down about a swing shaft attached to the front side in the front-rear direction as a fulcrum. With this configuration, the rear side of the seat can be pivoted downward more than the front side of the seat, allowing the user to sit deeply on the seat.

[0007] Moreover, it is preferable that the rocking mechanism is constituted by an air cell. With this configuration, the seat can be swung up and down with a simple structure.

[0008] It is also preferable that a pair of the rocking mechanisms are provided, one on the left and one on the right. With this configuration, the seat can be stably swung up and down.

[0009] It is also preferable that the frame is provided with a rocking restriction portion for restricting downward rocking of the seat portion. This configuration can prevent the seat from lowering more than necessary.

[0010] It is also preferable that the backrest is provided with a massage mechanism, and the seat is configured to swing downward so that the massage mechanism can massage the user's lower back or buttocks. With this configuration, the seat can be swung downward to massage the entire upper body from the waist to the shoulders, regardless of whether the user is tall or short.

[0011] It is preferable that the control unit moves the massage mechanism to a storage position when the power of the massage machine is turned off, and that the storage position is within a portion of the treatment range that is hidden by the seat swinging upward. With this configuration, when the massage machine is not in operation (when the power is turned off), it is possible to prevent the massage mechanism from coming into contact with the user when the user sits on the massage machine, causing discomfort to the user. Effect of the Invention

[0012] According to the present invention, even if a user sits tall, the entire upper body can be massaged without any part of the upper body being exposed from the backrest. [Brief description of the drawings]

[0014] [Overall configuration of the massage machine] The overall configuration of the massage machine 1 according to one embodiment of the present invention will be described below. FIG. 1 is a perspective view of a massage machine 1 according to an embodiment of the present invention. FIG. 2 is a view of the massage machine 1 according to an embodiment of the present invention as seen from the left. More specifically, this is a state before the rocking mechanism E is driven (a state in which the seat part 3 is rocked downward). FIG. 3 is a view of the massage machine 1 according to an embodiment of the present invention as seen from the left. More specifically, this is a state after the rocking mechanism E is driven (a state in which the seat part 3 is rocked upward). FIG. 4 is a view showing the seat part 3 according to an embodiment of the present invention, where (a) is a plan view and (b) is a perspective view. The inside of the backrest part 4 is visualized so that the treatment range W of the massage mechanism 6 provided in the backrest part 4 can be seen.

[0015] As shown in Fig. 1 to Fig. 6, a massage machine 1 according to an embodiment of the present invention is composed of a seat 3 on which a user sits, a backrest 4 on which the user leans, which is provided at the rear of the seat 3, a footrest 5 provided at the front of the seat 3, and armrests 2 attached to the sides of the seat 3. The massage machine 1 also has a massage section M (massage mechanism 6, buttocks massage section 3a, leg massage section 5a) that massages the user, a control section 7 that controls the functions of the massage machine 1, and a controller 8 that performs various operations on the massage machine 1. Note that the arrangement of the massage section M is an example and is not limited to this.

[0016] [Seat configuration] As shown in Fig. 4, the seat 3 is composed of a rectangular member that is long in the left-right direction. On the upper surface of the seat 3, a pair of buttock massage parts 3a (massage parts M) are provided on the left and right for massaging the buttocks of a user seated on the seat 3. The buttock massage parts 3a are composed of air cells that expand and contract by supplying and discharging air. It is preferable that the left and right buttock massage parts 3a are configured so that they can expand and contract independently. The configuration of the massage section M arranged on the seat 3 is an example and is not limited to this. For example, a thigh massage section (not shown) for massaging the thighs may be provided, or the buttock massage sections 3a may be of different sizes and provided in pairs on the front, back, left and right.

[0017] A first rocking shaft C1 is provided on both the left and right sides of the seat 3 (more specifically, on the front and rear sides of the left and right sides of the seat 3). The seat 3 is free to rock up and down with the first rocking shaft C1 as a fulcrum. By using the first rocking shaft C1 as a fulcrum, the rear side of the seat 3 can be rocked downward more than the front side of the seat 3, allowing the user to sit deeply on the seat 3. In other words, the seat 3 is inclined downward toward the rear (see FIG. 2). The first rocking shaft C1 is inserted into a hole H1 provided in the frame F (more specifically, the second frame F2). The frame F will be described later. The first oscillation shaft C1 constitutes a part of the oscillation mechanism E. The oscillation mechanism E will be described later.

[0018] [Backrest configuration] As shown in Figs. 1 to 3, the backrest 3 supports the upper body of the user. The backrest 4 is composed of a rectangular member that is long in the height direction. A guide rail 16 is provided inside the backrest 4 (see Fig. 1), and a massage mechanism 6 serving as a massage unit M is provided via the guide rail 16. The massage mechanism 6 moves up and down along the guide rail 16, so that it can massage a treatment area W (W1, W2).

[0019] More specifically, by rocking the seat 3 downward, the treatment range W2 of the massage mechanism 6, which is hidden when the seat 3 is in the upward position, is exposed, and the user's waist or buttocks can be massaged. This prevents the upper body from protruding from the backrest 4, regardless of whether the user is high or low in seat height, and allows the entire upper body of the user, from the waist to the shoulders, to be massaged.

[0020] The front surface of the backrest 4 is covered with a cover member, and the massage mechanism 6 is capable of massaging the back of the torso (e.g., shoulders, waist, etc.) of a user seated on the seat 3 through the cover member. Although not shown, air cells may be provided as massage units M at various locations on the backrest 4.

[0021] A pair of second rocking shafts C2 extending in the left-right direction are provided on the sides of the backrest 4 below the center. The second rocking shafts C2 are inserted into holes H2 provided in a frame F (more specifically, the fourth frame F4) described below. In other words, the backrest 4 can rock in the front-rear direction relative to the frame F with the second rocking shafts C2 as a fulcrum. Although not shown, the backrest 4 is caused to swing forward and backward by driving an actuator. The actuator is controlled by the control unit 7. The control unit 7 will be described later.

[0022] [Configuration of the rocking mechanism] 2, 3 and 6, the rocking mechanism E is for rocking the seat 3 up and down relative to the frame F. The rocking mechanism E is composed of a combination of multiple members. More specifically, the rocking mechanism E is composed of an air cell 20 attached to the upper surface of the rocking restriction part 21, and a first rocking shaft C1 attached to both the left and right sides of the seat 3. By employing the air cell 20 in the rocking mechanism E, the seat 3 can be rocked up and down with a simple structure.

[0023] A pair of air cells 20 are attached to the left and right of a plate-shaped rocking control part 21 attached to the frame F (see FIG. 6(b)). Providing a pair of left and right air cells 20 allows the seat part 3 to stably rock up and down. The air cells 20 are attached so that they expand and contract with the front side in the front-rear direction as a fulcrum. By bringing the attachment position of the first rocking shaft C1 and the attachment position of the air cells 20 close to each other, the amount of expansion of the air cells 20 can be maximized by the principle of leverage (fulcrum, point of force, point of action), and the rocking range of the seat part 3 in the up and down direction can be ensured.

[0024] The rocking mechanism E is controlled by the control unit 7. More specifically, when the power supply of the massage machine 1 is turned OFF, the control unit 7 controls the rocking mechanism E (more specifically, expands the air cells 20) to rock the seat 3 upward, thereby hiding a part of the treatment area W (treatment area W2) of the massage mechanism 6 that was exposed. Also, when the power supply of the massage machine 1 is turned ON, the control unit 7 controls the rocking mechanism E (more specifically, contracts the air cells 20) to rock the seat 3 downward, thereby exposing the treatment area W2 of the massage mechanism 6 that was hidden. In this way, the upper half of the user's body from the waist to the buttocks can be massaged by the massage mechanism 6.

[0025] [Footrest section configuration] As shown in FIG. 1, the footrest section 5 is provided with a pair of recesses 5b on the left and right into which the user's legs can be inserted. Leg massage sections 5a (massage sections M) for massaging the user's legs are provided on the inner walls on both the left and right sides of the recess 5b. The leg massage sections 5a are made of air cells that expand and contract by supplying and discharging air. More specifically, one leg massage section 5a is provided on each of the inner walls on both the left and right sides of the right recess 5b, and one leg massage section 5a is provided on each of the inner walls on both the left and right sides of the left recess 5b. It is preferable that each leg massage section 5a is configured to be able to expand and contract independently. In addition, a sole massage section (not shown) for massaging the soles of the user's feet may be provided on the bottom surface of the recess 5b.

[0026] The footrest portion 5 is attached to the front side of the seat portion 3. More specifically, the footrest portion 5 is attached to the seat portion 3 via a shaft (not shown) extending in the left-right direction. Although not shown, an actuator is attached to the back surface of the footrest portion 5. By driving the actuator, the footrest portion 5 can be swung up and down relative to the seat portion 3, with the shaft extending in the left-right direction as a fulcrum. The driving of the actuator is controlled by the control portion 7. The control portion 7 will be described later. The footrest portion 5 may be provided with an extension means (not shown) that is movable in the front-rear direction relative to the seat portion 3.

[0027] [Control Unit Configuration] FIG. 5 is a block diagram of the massage machine 1 according to an embodiment of the present invention. As shown in Fig. 5, the massage machine 1 is provided with a control unit 7 consisting of a microcomputer and the like for operating the massage mechanism 6 and the air supply and exhaust device 9. This control unit 7 is provided below the seat 3 and is connected to a controller 8 that is operated by the user. The user operates the controller 8 to perform various massage operations.

[0028] [Configuration of the exhaust system] 5, the air supply / exhaust device 9 is composed of a pump 9a for supplying air to the air cell 20 and each massage part 3a, 5a, and a valve 9b for connecting the air cell 20 and each massage part 3a, 5a to the pump 9a. By turning the valve 9b on and off, air can be sucked in and exhausted to the air cell 20 and each massage part 3a, 5a. That is, by turning on the valve 9b, an air flow path can be secured, and air can be sucked into the air cell 20 and each massage part 3a, 5a. Also, by turning off the valve 9b, air contained in the air cell 20 and each massage part 3a, 5a can be exhausted. At least the valve 9b connected to the air cell 20 is configured as a retention valve. By configuring the valve 9b as a retention valve, even if the power of the massage machine 1 is turned off, the air is not exhausted from the air cell 20 and each massage part 3a, 5a due to the action of the valve 9b, and the expanded state can be maintained.

[0029] [Frame configuration] FIG. 6 shows a frame F of a massage machine 1 according to an embodiment of the present invention, where (a) is a view seen from the left, (b) is a plan view, and (c) is a perspective view. 6, the frame F is configured by combining multiple members. More specifically, the frame F is made up of a first frame F1 having a rod shape extending in the front-rear direction, a second frame F2 having a rod shape extending in the up-down direction, a third frame F3 having a rod shape extending in the front-rear direction, a fourth frame F4 having a rod shape extending in the up-down direction, and a fifth frame F5 having a rod shape extending in the left-right direction.

[0030] The first frames F1 are provided in a pair on the left and right with a predetermined distance between them. A fifth frame F5 is provided between the pair of left and right first frames F1. More specifically, the fifth frames F5 are provided on the front and rear sides of the first frame F1 (the fifth frames F5 are provided in a pair on the front and rear sides). That is, the first frame F1 and the fifth frame F5 are combined with each other to form the shape of the Roman numeral "2."

[0031] The second frame F2, which extends in the up-down direction, is attached to the left and right sides of the front side of the first frame F1. More specifically, the second frame F2 is attached to the upper surface of the first frame F1, at the location where the first frame F1 and the front fifth frame F5 are joined. A hole H1 is provided in the upper part of the second frame F2, which passes through in the left-right direction. A first rocking shaft C1 provided in the seat portion 3 is inserted through this hole H1. In other words, when the rocking mechanism E is driven, the seat portion 3 rocks up and down via the first rocking shaft C1 inserted through the hole H1.

[0032] Further, a fourth frame F4 extending in the vertical direction is attached to the left and right sides on the rear side of the first frame F1. More specifically, the fourth frame F4 is attached to the upper surface of the first frame F1 at a location where the first frame F1 and the rear side fifth frame F5 are joined. A hole H2 is provided on the upper side of the fourth frame F4, passing through in the horizontal direction. A second rocking shaft C2 provided on the backrest part 4 is inserted through this hole H2. The massage machine 1 is provided with an actuator (not shown) for reclining the backrest part 4 in the front-rear direction, and by controlling the drive of the actuator (not shown) with the control unit 7, the backrest part 4 can be reclined in the front-rear direction via the second rocking shaft C2 inserted through the hole H2.

[0033] A third frame F3 extending in the front-rear direction is provided between the second frame F2 and the fourth frame F4. By providing the third frame F3, the strength of the frame F can be ensured. Furthermore, a rocking restriction part 21 for restricting rocking of the seat 3 (more specifically, for restricting the seat 3 from lowering more than necessary) is provided on the upper surface of the front side in the front-rear direction of the third frame F3. The rocking restriction part 21 is made of a plate-shaped member. The rocking restriction part 21 is preferably made of a metal member. By making the rocking restriction part 21 of a metal member, the weight of the seat 3 and the user seated on the seat 3 can be firmly received.

[0034] A pair of left and right air cells 20 (part of the rocking mechanism E) for rocking the seat 3 up and down are provided on the upper surface of the rocking restriction part 21. The air cells 20 are attached to the rocking restriction part 21 so that they can expand and contract with the front side in the front-rear direction as a fulcrum. By providing a pair of left and right air cells 20, the size of the air cells 20 can be made compact, while the seat 3 can be rocked up and down stably (see FIG. 6(b)). The shape and number of the air cells 20 are merely examples and are not limited to these. For example, as shown in Fig. 8, it may be configured with one large air cell, or three air cells 20 may be provided. Also, it does not have to be the air cells 20, and any configuration that can rock the seat portion 3 in the up and down direction may be used, such as a spring or an actuator (not shown).

[0035] The combination of the frames F1 to F5 is merely an example and is not limited to this. For example, the third frame F3 may be configured to be inclined upward or downward from the second frame F2 to the fourth frame F4, or another frame (such as a sixth frame (not shown)) may be further combined between the left and right second frames F2.

[0036] Fig. 8 is a plan view showing the frame F of the massage machine 1 according to another embodiment of the present invention. The difference from Fig. 6 is the size and number of the air cells 20 constituting the rocking mechanism E, but the configuration of the frame F itself is the same as that of Fig. 6, so a description thereof will be omitted. As shown in Fig. 8, in another embodiment, there is one air cell 20 for rocking the seat 3 in the up-down direction. The air cell 20 has a rectangular shape that is long in the left-right direction. The air cell 20 is attached to the upper surface of a rocking restriction part 21 provided on the frame F so as to expand with the front side in the front-rear direction as a fulcrum. Since the air cell is larger than the air cell 20 in this embodiment, the amount of expansion of the air cell 20 can be sufficiently ensured.

[0037] FIG. 7 is a flow diagram showing a series of steps from powering on the massage machine 1 to powering it off (from the start to the end of a massage course). As shown in Fig. 7, after the user sits on the massage machine 1, the user turns on the power of the massage machine 1 to enable selection of a massage course (S1). When the power of the massage machine 1 is turned on, the control unit 7 controls the rocking mechanism E (more specifically, contracts the air cells 20 that have been inflated) to rock the seat 3 downward (S2). This exposes the treatment range W2 of the massage mechanism 6 that was hidden. In this state, the massage course can be started, allowing the massage mechanism 6 to massage the upper half of the user's body (S3).

[0038] When the massage course is completed (S4), the control unit 7 controls the rocking mechanism E (more specifically, expands the contracted air cells 20) to rock the seat 3 upward and hide the exposed treatment range W2 of the massage mechanism 6 (S5). Then, the power of the massage machine 1 is turned off (S6), and the rocking mechanism E is controlled (to maintain the expansion of the air cells 20) (S7). The timing of executing S5 and S6 is merely an example and is not limited to this. For example, S5 may be executed first and then S6 may be executed, or S6 may be executed first and then S5 may be executed. Also, S5 and S6 may be executed substantially simultaneously.

[0039] The control unit 7 moves the massage mechanism 6 to the stored position when the power of the massage machine 1 is turned off in accordance with the end of the massage course (S4). The control unit 7 may move the massage mechanism 6 to the stored position in accordance with the timing (S5) when the air cells 20 expand after the massage course is finished, or when the power is turned off (including before and after the power is turned off). In other words, the .... The stored position is within a part of the treatment range W that is hidden by the seat 3 swinging upward (see FIG. 3). More specifically, it refers to the treatment range W2 of the treatment range W of the massage mechanism 6. This makes it possible to prevent the massage mechanism 6 from coming into contact with the user when the user sits on the massage machine 1 while the massage machine 1 is not in operation (when the power is OFF), thereby preventing the user from feeling uncomfortable.

[0040] [Another Example 1] 9 is a diagram of the massage machine according to another embodiment 1 of the present invention as seen from the left, where (a) is a diagram showing a state before the rocking mechanism E is driven, and (b) is a diagram showing a state after the rocking mechanism E is driven. More specifically, by driving the rocking mechanism E, the seat part 3 is rocked up and down with the front side of the seat part 3 in the front-rear direction as a fulcrum.

[0041] 9, the rocking mechanism E is provided for the rocking regulation part 21. More specifically, the rocking regulation part 21, which is made of a plate-like member, is attached to a frame F (not shown) so as to be substantially horizontal with the ground surface of the massage machine 1. A guide member 32 for guiding the rocking of the seat part 3 in the up-down direction is provided on the upper surface of the rocking regulation part 21, and an air cell 20 for rocking the seat part 3 in the up-down direction is provided in front of the guide member 32.

[0042] The guide member 32 is a plate-like member that is long in the vertical direction, and more specifically, has a shape that is slightly curved from the rear to the front. A hole H3 that is long in the vertical direction is provided in the center of the guide member 32. A third rocking shaft C3 provided on the rear side of the side of the seat 3 is inserted into the hole H3. A total of four rocking shafts (a first rocking shaft C1 and a third rocking shaft C3) are provided in the seat 3. More specifically, the first rocking shafts C1 are provided on the left and right sides of the side of the seat 3, and a pair of third rocking shafts C3 are provided on the left and right sides of the rear side. The first rocking shaft C1 is attached to the frame F, and the third rocking shaft C3 is inserted into a hole H3 provided in the guide member 32. In other words, the seat 3 can be swung up and down with the first swiveling axis C1 as a fulcrum, and the third swiveling axis C3 can guide the swiveling of the seat 3 in the up and down direction.

[0043] The seat 3 is attached above the rocking motion restricting unit 21. More specifically, the seat 3 is attached to the frame F so as to be tilted downward from the front side to the rear side by the first rocking axis C1 attached to the front side of the seat 3. The rocking motion restricting unit 21 prevents the seat 3 from tilting downward more than necessary. Therefore, when the air cell 20 of the rocking mechanism E is inflated, the rear side of the seat 3 rocks upward with the first rocking axis C1 as a fulcrum, and part of the treatment range of the massage mechanism 6 provided on the backrest 4 can be hidden.

[0044] That is, when the power of the massage machine 1 is turned OFF, the control unit 7 controls the driving of the rocking mechanism E (more specifically, the air cell 20), and the air cell 20 expands to rock the seat 3 upward. This makes it possible to hide a part of the treatment area of ​​the massage mechanism 6. Also, when the power of the massage machine 1 is turned ON, the control unit 7 controls the driving of the rocking mechanism E (more specifically, the air cell 20), and the air cell 20 contracts to rock the seat 3 downward. This makes it possible to expose the treatment area of ​​the massage mechanism 1 that was hidden, and the upper body of the user can be massaged by the massage mechanism 6.

[0045] [Another Example 2] 10 is a diagram of a massage machine 1 according to another embodiment of the present invention as seen from the left, where (a) is a diagram showing a state before the rocking mechanism E is driven, and (b) is a diagram showing a state after the rocking mechanism E is driven. More specifically, by driving the rocking mechanism E, the entire seat portion 3 is rocked up and down while maintaining the inclination angle of the seat portion 3 relative to the backrest portion 4.

[0046] As shown in Fig. 10, the rocking mechanism E is provided for the rocking restriction part 21. More specifically, the rocking restriction part 21, which is made of a plate-like member, is attached to the frame F (not shown) so as to be inclined downward from the front side to the rear side. On the upper surface of the rocking restriction part 21, a pair of guide members 32 for guiding the rocking of the seat part 3 in the up-down direction is provided on the front, back, left and right sides (four in total), and an air cell 20 for rocking the seat part 3 in the up-down direction is provided between the guide members 32.

[0047] The guide member 32 is a plate-shaped member that is long in the vertical direction. A hole H3 that is long in the vertical direction is provided in the center of the guide member 32. A first rocking shaft C1 provided on the side of the seat 3 is inserted into the hole H3. A total of four first rocking shafts C1 are provided in the seat 3. More specifically, a pair of left and right first rocking shafts C1 are provided on the sides of the seat 3, one on the front side of the seat 3, and another pair on the rear side of the seat 3. In other words, the seat 3 is guided in its vertical rocking movement by the four first rocking shafts C1.

[0048] Since the rocking control section 21 is arranged at an angle relative to the frame F, when the air cell 20 of the rocking mechanism E is inflated, the seat section 3 rocks upward while maintaining the tilt angle relative to the backrest section 4, thereby hiding a part of the treatment range W (treatment range W2) of the massage mechanism 6 provided on the backrest section 4. That is, when the power of the massage machine 1 is turned off, the control unit 7 controls the driving of the rocking mechanism E (more specifically, the air cell 20), and the air cell 20 expands to rock the seat 3 upward. In this way, a part of the treatment area W of the massage mechanism 6 (treatment area W2) can be hidden.

[0049] When the power of the massage machine 1 is turned on, the control unit 7 controls the driving of the rocking mechanism E (more specifically, the air cell 20), and the air cell 20 contracts to rock the seat 3 downward. This exposes the treatment area W (treatment area W2) of the massage mechanism 1 that was previously hidden, allowing the massage mechanism 6 to massage the upper half of the user's body. [Industrial Applicability]

[0050] The present invention is applicable to a massage machine capable of massaging the entire upper body of a user, even if the user is tall, without exposing part of the upper body from the backrest. [Explanation of symbols]
