In addition, the massage chair rotates the seat portion (1) and the backrest portion (2) forward at a certain angle from the reference position so that the user can easily stand up with little force when the user stands up from the massage chair after using the massage chair. It is provided with a standing assistance means and a standing assistance means to perform a standing assistance function that adjusts the user to an angle that makes it easy for the user to stand up.

Referring to Figures 2 to 6, the support structure constituting the seat part 1, backrest part 2, and leg massage part 4 of the massage chair is a base frame placed on the floor and supporting the entire massage chair. (10), a tilting axis 21 installed to extend laterally on the upper front part of the base frame 10, the front part is installed to rotate in the vertical direction around the tilting axis 21, and the base is tilted by a standing assistance tilting means. A tilting frame 20 that rotates with respect to the frame 10, a seat frame 30 installed on the upper part of the tilting frame 20 to support the user's buttocks, and a seat frame 30 extending upward at the rear end of the seat frame 30. The seat frame 30 and the backrest frame 40 are installed and rotated with respect to the backrest frame 40 and the tilting frame 20, which support the user's back, so that the seat frame 30 and the backrest frame are relative to the ground. It includes a reclining means for varying the angle of (40).

The seat frame 30 and the backrest frame 40 are parts that form the skeleton of the seat portion 1 and the backrest portion 2 of the massage chair, respectively. The seat frame 30 and the backrest frame 40 are integrally connected. A rail 90 is installed on which the sample module 100 moves to massage the user's back, shoulders, waist, hips, thighs, etc. by tapping or massaging the user's body.

The base frame 10 includes a plurality of first base frames 11 placed on the floor, and a plurality of second base frames 12a and 12b installed vertically in front and behind both sides of the first base frame 11. ) and a reinforcement frame 13 connecting the front second base frame 12a and the rear second base frame 12b to each other. Among the plurality of second base frames 12a and 12b, a tilting shaft 21 is installed at the upper end of the second base frame 12a disposed at the front to extend horizontally in the lateral direction.

The tilting frame 20 forms a roughly rectangular skeleton, and rotatably supports the seat frame 30 and the backrest frame 40 on the base frame 10. The lower front portions on both sides of the tilting frame (20) are connected to the tilting axis (21), and the lower front portions rotate in the vertical direction around the tilting shaft (21) to assist the seat frame (30) and the backrest frame (40) in standing. Performs the angle adjustment function.

The tilting frame 20 rotates in the vertical direction about the tilting axis 21 by the standing assistance tilting means installed at the lower part of the tilting frame 20. The standing assistance tilting means includes a standing actuator 60 whose front end is hinged to the front of the base frame 10 and whose rear end is hinged to the bottom of the rear end of the tilting frame 20. The standing actuator 60 is an electric actuator having an operating rod 61 that expands and contracts while making a linear reciprocating movement by receiving power from a motor operated by power supplied from the control device of the massage chair. The operating rod is moved by the operation of the motor. When (61) is extended, the tilting frame (20) rotates upward around the tilting axis (21) and performs a standing assistance operation to push the body forward. When the operating rod (61) is contracted, the tilting frame (20) It rotates downward around the tilting axis 21 and returns to the initial position. In this embodiment, the standing actuator 60 uses an electric actuator operated by a motor. However, unlike this, the standing actuator 60 uses an operating rod that is extended by the pressure of fluid (e.g., air) supplied from a pneumatic supply device (not shown). A hydraulic actuator provided may also be applied.

A seat frame 30 is rotatably installed on the upper part of the tilting frame 20. And a backrest frame 40 is installed at the rear end of the seat frame 30 to extend upward. In this embodiment, the backrest frame 40 is formed integrally with the rear end of the seat frame 30 and is configured to rotate together with the seat frame 30, but the backrest frame 40 rotates relative to the seat frame 30. This could possibly be connected.

The seat frame 30 and the backrest frame 40 are installed on the tilting frame 20 so that their angles can be varied up and down by a reclining means, so that they can perform a reclining function. The reclining means for this includes a reclining rail 72 that is curved up and down and installed on both sides of the seat frame 30 and/or the backrest frame 40, and a reclining rail (72) on both sides of the tilting frame 20. A plurality of reclining rollers 73 are installed to be inserted into 72 and guide the reclining rail 72, one end is hinged to the rear end of the tilting frame 20, and the other end is hinged to the front end of the seat frame 30. It may include a reclining actuator 70 that is hinged and has an operating rod 71 that expands and contracts while moving linearly by a motor. In this embodiment as well, the reclining actuator 70 is an electric actuator operated by a motor. However, unlike this, a hydraulic actuator in which the operating rod expands and contracts by the pressure of fluid supplied from a pneumatic supply device (not shown) is applied. You might be able to do it.

Therefore, when the motor of the reclining actuator 70 operates and the operating rod 71 is extended, the reclining rail 72 of the seat frame 30 and the backrest frame 40 moves against the reclining roller 73 of the tilting frame 20. As the user moves forward under guidance, the seat frame 30 rises while the backrest frame 40 descends so that the user is in a lying position (see Figure 3 (A)). In this state, when the motor of the reclining actuator 70 operates in the opposite direction and the operating rod 71 contracts, the reclining rail 72 of the seat frame 30 and the backrest frame 40 moves the reclining roller 73 of the tilting frame 20. While moving backward under the guidance of ), the seat frame 30 descends while the backrest frame 40 rises to return to the initial sitting position of the user (see drawing in Figure 3 (B)).

The massage chair has a seat frame (30) so that the user can comfortably receive a massage in a sitting position even in the normal state (state shown in (B) of FIG. 3) in which the reclining function as described above is not performed. ) and the backrest frame 40 are tilted rearward at a certain angle. In the normal state of the massage chair, the seat frame 30 is lifted upward at approximately 14 to 15 degrees based on a horizontal axis with respect to the ground. Therefore, it takes a lot of strength when the user tries to stand up from the massage chair after using it.

Accordingly, when the user wants to stand up from the massage chair after using the massage chair, the standing actuator 60, which is a tilting means for standing assistance, can be operated to execute the standing assistance mode as shown in (C) of FIG. 3. For example, after completing use of the massage chair, when the user executes the standing assistance mode through a command input device provided in the massage chair or a dedicated app on the smartphone, the control device of the massage chair operates the motor of the standing actuator 60. to extend the operating rod 61 of the standing actuator 60. Accordingly, in the normal state as shown in (B) of FIG. 3 and FIG. 4, the tilting frame 20 rotates upward (clockwise in the drawing) around the tilting axis 21, and the tilting frame 20 in FIG. (C) As shown in the drawing and FIG. 5, the seat frame 30 is lowered by approximately 10° relative to the axis horizontal to the ground, and the backrest frame 40 is rotated forward, so that the user's posture is forward. Because the posture is slightly standing, the user can comfortably stand up from the massage chair with little force.

In order to make it easier for the user to stand in the standing assistance mode of the tilting frame 20 by the standing actuator 60, the standing assist means can apply a force to directly push the user's body forward. That is, the standing assistance means pushes the user's body, especially the user's buttocks, forward and upward in a standing assistance mode in which the tilting frame 20 rotates forward and upward around the tilting axis 21 by the standing assistance tilting means. It is designed to make it easier for the user to stand by applying force.

In this embodiment, the standing assistance means includes a seat plate 31 supporting the user's buttocks on the upper side of the seat frame 30, and moving the seat plate 31 upward around the front seat hinge axis 32. It includes a seat lifting unit that applies a force to push the user's buttocks toward the upper front by rotating it.

The seat plate 31 is a structure having a three-dimensional shape corresponding to the user's buttocks and thighs so that the user's buttocks and thighs are seated and supported when the user sits on the seat 1 (see FIG. 1) of the massage chair. As, the front portion is installed to be rotatable up and down about the seat hinge axis 32, which is installed to extend laterally on the front portion of the seat frame 30.

The seat lifting unit is disposed between the seat frame 30 and the lower surface of the seat plate 31, and is a lifting airbag (33) that expands under the pressure of air supplied from the outside and presses the seat plate 31 upward to lift it. ) can be composed of.

Therefore, in the standing assistance mode, when the tilting frame 20 rotates upward by the operation of the standing actuator 60 and the user's body (upper body part) moves forward, air is supplied to the lifting airbag 33 and expands to cover the seat plate. When (31) rotates upward around the seat hinge axis 32, the user's buttocks are pushed forward and upward, further increasing the standing assistance force, allowing the user to easily stand up with less force.

In this embodiment, the standing assistance force is further increased in the standing assistance mode by rotating the seat plate 31 installed on the upper side of the seat frame 30 using the lifting airbag 33, but the actuator whose rod is expanded and contracted by a motor It may be possible to rotate the seat plate 31 by applying .

Additionally, unlike the above-described standing assistance means, the standing assistance force may be increased by using the sample module 100 as a standing assistance means, as shown in other embodiments in FIGS. 7 and 8.

*The standing assistance means shown in FIGS. 7 and 8 includes a moving part 120 (FIG. 2) that moves along the rail 90 (see FIG. 2) installed along the seat frame 30 and the backrest frame 40. (reference) and a sample module 100 installed on the front surface of the moving unit 120.

The sample module 100, like the sample module configured in a typical massage chair, is installed on a motor (not shown) to vibrate and/or rotate back and forth and left and right, and includes a plurality of sample elements ( 110) is provided. However, unlike the existing sample module, the sample module 100 moves to a position corresponding to the user's buttocks and waits when the standing assistance mode is selected, and then moves to a tilting frame by the standing actuator 60. When (20) rotates upward, the upper medical device 110 moves forward and is controlled to apply a forward pushing force to the user's hip area.

That is, the sample module 100 has the function of massaging the user's body while moving along the rail 90 installed on the seat frame 30 and the backrest frame 40, and also has the function of assisting the standing motion in the standing assistance mode. It is also designed to be able to perform.

Therefore, when the standing assistance means is configured using the seat plate 31 and the lifting airbag 33 as in the first embodiment described above, the sample module 100 is used together as the standing assistance means in the same manner as the second embodiment. It may be possible to double the standing support power.

Meanwhile, referring again to FIGS. 2 to 5, the leg frame 50 constituting the leg massage unit 4 is rotatably connected to the front end of the seat frame 30. The leg frame 50 is designed to support the user's calves and feet, and its upper end is rotatable around a hinge axis 51 installed at the front end of the seat frame 30. The leg driving unit for rotating the leg frame 50 around the hinge axis 51 has a rear end hinged to the rear end of the seat frame 30, a front end hinged to the leg frame 50, and linear reciprocation by a motor. It may include a leg actuator 80 having an operating rod 81 that expands and contracts while exercising.

Since the leg frame 50 is connected to the front end of the seat frame 30 and installed to extend downward, the standing actuator 60 operates when the leg frame 50 is folded, causing the front end of the seat frame 30 to move downward. When rotating, the lower end of the leg frame 50 may be damaged by hitting the floor, the base frame 10, or a structure installed on the base frame 10, or vibration and noise may occur due to impact.

To prevent this, the hinge bracket 52, on which the hinge axis 51 is installed at the front end of the seat frame 30, is installed to be rotatable up and down about the bracket axis 53, so that the tilting frame 20 can tilt. When the lower end of the leg frame 50 touches the floor or the base frame 10 by rotating upward about the axis 21, the hinge bracket 52 is tilted upward at a certain angle about the bracket axis 53. It rotates to prevent shock.

As described above, the standing assistance device for the massage chair of the present invention includes a seat frame 30 and a backrest frame 40 installed on a tilting frame 20 that is installed to rotate with respect to the base frame 10, and a standing actuator ( 60), the seat frame 30 and the backrest frame 40 can be tilted forward by applying force to the rear upper part of the rear end of the tilting frame 20 to lift the rear of the tilting frame 20 upward.

Therefore, the configuration for adjusting the seat frame 30 and the back frame 40 to an angle for standing assistance can be simplified, and the advantage of stable standing assistance operation can be obtained.

That is, the massage chair is equipped with various electrical and mechanical parts such as motors, air compressors, and control devices for driving sample modules and air cells for massage, and these electro-mechanical parts include the base frame 10 and the seat frame. (30) It must be placed in the space between to minimize the increase in size of the massage chair.

The massage chair of the present invention consists of a tilting frame (20) and a standing actuator (60) in the space between the base frame (10) and the seat frame (30), so that the seat frame (30) and the backrest frame ( 40) can be rotated forward (counterclockwise in the drawing) to implement a standing assistance function.

In addition, the present invention, when performing a standing assistance mode in which the standing actuator 60 is operated to rotate the tilting frame 20 upward, the user is able to stand by applying a force to push the user's buttocks forward using the standing assistance means. Assisting power can be further increased. Therefore, the user's standing motion can be performed more easily and comfortably.

In the above, the technical idea of the present invention has been described along with the accompanying drawings, but this is an exemplary description of a preferred embodiment of the present invention and does not limit the present invention. In addition, it is clear that anyone skilled in the art of the present invention can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
