[0040] In an acupressure bed (1) according to one embodiment of the present invention, an indirect acupressure method is applied in which an acupressure member (111) moves up and down by means of a movable module (120) capable of adjusting the inclination direction, thereby enabling the user to receive an optimal acupressure service. Since the inclination direction of the movable module (120) is adjustable, it can have a smaller size compared to a fixed movable module having a bidirectional inclination, thus enabling the acupressure bed (1) to be implemented as a movable type.

[0041] The acupressure bed (1) according to the present embodiment has a bed frame (10) as its basic framework, which includes a mounting plate on which a mattress supporting a user lying down is mounted, and a support member that supports the same.

[0042] For the convenience of understanding and explaining the invention, the following description will assume the head (head part) is in the front and the feet (foot part) are in the rear, based on the state where the user is lying on the acupressure bed (1), and the left and right sides correspond to the left and right sides of the user's body.

[0043] The bed frame (10) may have a rectangular shape with open top and bottom, including a headboard located at the front, a footboard located at the rear, and a pair of sideboards located on the left and right sides, respectively.

[0044] An acupressure section (100) is positioned along a longitudinal centerline connecting the front and rear of the bed frame (10). The acupressure section (100) may be positioned on one side of the bed frame (10), specifically at a location corresponding to the part where spinal acupoints are located when a user of average height lies down (the part from the neck to the buttocks). A plurality of acupressure rods (112) installed within the acupressure section (100) move up and down to apply pressure to the spinal acupoints.

[0045] In this embodiment, since acupressure is performed while a person is lying on a mattress, the pressure applied to the body during acupressure is dispersed, thereby providing comfort.

[0046] An opening (20) is formed in the mounting plate of the bed frame (10). A pressure member plate (110) with a left-right symmetrical structure with respect to the centerline of the pressure member (100) can be placed within the opening (20).

[0047] A mattress can be mounted on the mounting plate of the bed frame (10). A mounting groove corresponding to the opening (20) of the mounting plate is also formed on the rear side of the mattress, and a plurality of through holes corresponding to acupressure members are formed within the mounting groove, so that the upper end of the acupressure member (111) is positioned within the mounting groove and then moves up and down in the vertical direction according to the movement of the moving module (120), allowing it to smoothly move in and out relative to the upper surface of the mattress, thereby performing acupressure on the body of the user lying on the mattress.

[0048] The pressure member (100) may include a moving module (120) that moves back and forth on a floor plate (102) and a pressure member (111) that moves up and down by the moving module (120).

[0049] The pressure member (111) is installed on a pressure member plate (110) spaced apart from the bottom plate (102) by a predetermined height. The pressure member plate (110) can be horizontally supported by a plurality of supports (125) installed on both the left and right sides of the bottom plate (102).

[0050] The pressure member plate (110) is a plate-shaped structure in which a plurality of vertical movement passages are formed along a plurality of rows. In each row, a predetermined number (e.g., one or two) of vertical movement passages are arranged on the left and right sides, respectively. In each vertical movement passage, a pressure rod (112) can be installed to be vertically movable.

[0051] A lubricating member may be provided on the lower side of the vertical movement passage into which the acupressure rod (112) is fitted to reduce wear and noise caused by friction between the vertically operating acupressure rod (112) and the vertical movement passage. The lubricating member is a ring-shaped member containing lubricating oil and can be fitted onto the acupressure rod (112) and installed on the acupressure member plate (110) together with the acupressure rod (112).

[0052] The acupressure stick (112) includes an acupressure head (1121) and a stick body (1122).

[0053] The acupressure head (1121) has a convex surface so that it can directly and gently apply acupressure to the user's body, especially to the spinal acupoints. Protrusions may be formed on the surface of the acupressure head (1121) to enhance the acupressure effect.

[0054] The rod body (1122) can be attached to the lower end of the acupressure head (1121). For example, the rod body (1122) may have a passage formed on the inside and its upper end may be fitted into the inner groove of the acupressure head (1121) and fixed with adhesive.

[0055] The lower part of the rod body (1122) is formed as a flat plane, so that the upward pressure from the inclined plate of the moving module (120) can be transmitted vertically to the rod body (1122). Additionally, the downward pressure applied to the acupressure rod (112) according to the user's weight can be transmitted to the inclined plate.

[0056] The pressure head (1121) has a larger diameter than the rod body (1122). The inner diameter of the vertical movement passage may be smaller than the diameter of the pressure head (1121) and larger than or equal to the diameter of the rod body (1122). Therefore, when the pressure rod (112) is fitted into the vertical movement passage, the pressure head (1121) has a structure that catches on the upper surface of the pressure member plate (110). A bushing is installed in the vertical movement passage so that the rod body (1122) can be moved up and down smoothly.

[0057] Referring to FIG. 4, a spring (1123) is interposed between the lower part of the pressure member plate (110) and the rod body (1122), so that when there is no external force, the pressure rod (112) can maintain a basic posture with a certain protruding height relative to the upper surface of the pressure member plate (110). In this case, a stopper protrudes from the lower circumference of the rod body (1122) to prevent the spring (1123) from coming off. In this basic posture, the upper part of the pressure rod (112), that is, the pressure head (1121), is positioned within the mounting groove of the mattress.

[0058] A coupling member may be provided at the bottom of the rod body (1122) with a through hole into which a connecting shaft (113) is fitted. A plurality of rod bodies (1122) of a plurality of acupressure rods (112) corresponding to one row are fitted onto a single connecting shaft (113), so that a plurality of acupressure rods (112) corresponding to one row can move up and down as a single unit.

[0059] When the roller (114) installed at the center of the connecting shaft (113) receives an upward force by the moving module (120), the pressure rod (112) fitted to the connecting shaft (113) also rises upward.

[0060] When the moving module (120) moves back and forth, the roller (114) is pushed up and down along the inclined surface formed by the inclined plate (200) installed on the upper part, thereby allowing the pressure rod (112) fitted to the connecting shaft (113) to move up and down.

[0061] Referring to FIG. 5, the connecting shaft (113) includes a shaft body (1131) having a cross-section with a diameter corresponding to the through hole of the coupling member.

[0062] A shaft head (1132) having a size larger than the through hole of the coupling member is formed at one end of the shaft body (1131). The shaft head (1132) includes a compressed piece (1132a) in which a portion of a certain length from the end of the shaft body (1131) is compressed, and an uncompressed piece (1132b) remaining without compression. During the process of compression by an external force, the compressed piece (1132a) takes on a shape that protrudes beyond the circumferential surface of the shaft body (1131).

[0063] A hanging groove (1133) may be formed in relief around the other end of the shaft body (1131). A fixing ring (1134) having a thickness corresponding to the width of the hanging groove (1133) may be installed in the hanging groove (1133).

[0064] Accordingly, when the connecting shaft (113) is installed in the through hole of the coupling member, the other end of the shaft body (1131) can easily pass through the through hole of the coupling member, but the shaft head (1132) cannot pass through and gets caught in the through hole of the coupling member. Then, by installing a fixing ring (1134) in the hook groove (1133) formed on the other end of the shaft body (1131) that has passed through the through hole of the coupling member, it can be caught in the through hole of the coupling member from the opposite direction as well.

[0065] That is, the connecting shaft (113) can be easily installed within the through hole of the coupling member through a first process of pushing the other end of the shaft body (1131) into the through hole of the coupling member and a second process of installing a rubber ring. This has the advantage of reducing the amount of work compared to the conventional method of forming hook grooves on both ends of the shaft body and installing a pair of rubber rings on each end.

[0066] In addition, in the past, the shaft body was not fixed during the process of installing the first rubber ring, requiring meticulous work by a skilled worker. However, in this embodiment, the shaft body (1131) is caught in the through hole of the coupling member by simply pushing it in, so there is an advantage that the worker's skill is not greatly required.

[0067] According to the embodiment, the connecting shaft (113) and the roller (114) may be omitted, and the pressure rods (112) may be raised individually. In this case, each of the pressure rods (112) may be raised by receiving an upward force while being directly supported by the moving module (120), particularly the inclined plate (200).

[0068] When the upward force disappears due to the movement of the moving module (120), the acupressure rod (112) descends due to gravity and the spring (1123) and returns to the basic position where the acupressure head (1121) is placed on the upper surface of the acupressure member plate (110).

[0069] The movement module (120) may include a driving body (240) and an inclined plate (200). The driving body (240) is a body part having a predetermined width and length, and is equipped with wheels so that it can move back and forth on its own or by external force.

[0070] When moving by an external force, one end of the conveyor belt (123) may be connected to the front end of the driving body (240). The other end of the conveyor belt (123) may also be connected to the rear end of the driving body (240).

[0071] The conveyor belt (123) forms a continuous closed curve together with the moving module (120). The conveyor belt (123) is connected between a conveyor motor (121) installed at one end (e.g., rear end) of the bottom plate (102) of the pressure part (100) and a tension pulley (122) installed at the other end (e.g., front end), and can operate like a conveyor belt by the conveyor motor (121). Thus, when the conveyor belt (123) operates according to the driving of the conveyor motor (121), the moving module (120) can move forward or backward.

[0072] A movement guide (124) is provided on the bottom plate (102) of the pressure point part (100), so that the driving body (240) can move along the movement guide (124) without deviating from the path.

[0073] The inclined plate (200) may be a flat plate having a predetermined width and length. A front curved surface (201) and a rear curved surface (202) having a predetermined curvature facing downward may be formed on the front and rear of the inclined plate (200).

[0074] On the lower surface of the inclined plate (200), a main shaft (203) for lifting, a front shaft (204) provided on the front side and functioning as a hinge shaft for rearward tilting, and a rear shaft (205) provided on the rear side and functioning as a hinge shaft for frontward tilting are arranged to extend in the left and right directions. Here, rearward tilting means a slope where the rear is high and the front is low, and frontward tilting means a slope where the front is high and the rear is low.

[0075] The main shaft (203) is supported by a pair of main shaft supports (2031). The front shaft (204) is supported by a pair of front shaft supports (2041). The rear shaft (205) is supported by a pair of rear shaft supports (2051).

[0076] Additionally, the moving module (120) may include a driving unit (242), a lifting unit (220), and a direction adjustment unit (210) for adjusting the inclination direction of the inclined plate (200).

[0077] The drive unit (242) may include a drive motor (2421), a gearbox (2422), a rotating shaft (2423), and a direction adjustment cam (230).

[0078] A drive motor (2421) is installed on one side of a driving body (240). The rotation axis of the drive motor (2421) may be arranged in the forward and backward directions. A gearbox (2422) for changing the direction of rotation is installed at the rear end of the drive motor (2421). For example, the gearbox (2422) may be composed of a bevel gear or a worm gear, which are direction-changing gears.

[0079] A left and right rotation axis (2423) is installed in the gearbox (2422). The rotation axis (2423) of the gearbox (2422) may intersect with the rotation axis of the drive motor (2421).

[0080] A cam mounting groove (2424) is provided around the circumference of the rotation axis (2423). A direction adjustment cam (230) may be installed in the cam mounting groove (2424). The direction adjustment cam (230) is a cylindrical device with a through hole formed in the center. An adjustment projection (231) is installed on the circumferential surface of the direction adjustment cam (230). The adjustment projection (231) may have a convex shape having a predetermined curvature.

[0081] The lifting guide (241) is installed on the other side of the driving body (240). An up-and-down guide rail (2411) may be formed on the inner surface of the lifting guide (241).

[0082] A lifting member (220) can be coupled to the lifting guide (241) so as to be slidably moved in the up and down direction. A vertical guide groove (221) having a width corresponding to a guide rail (2411) can be formed on the first side (outer side from the perspective of the moving module (120)) of the lifting member (220). That is, the guide rail (2411) of the lifting guide (241) is coupled within the vertical guide groove (221) of the lifting member (220), and the lifting member (220) can be lifted up and down along the guide rail (2411) of the lifting guide (241).

[0083] The lifting member (220) can be raised and lowered in conjunction with the rotation axis (2423). A lifting projection (232) formed on the bottom surface of the direction adjustment cam (230) can be slidably fitted into a horizontal guide groove (222) formed on the second side (inner side from the perspective of the moving module (120)) of the lifting member (220). When the lifting projection (232) rotates according to the rotation of the direction adjustment cam (230), the lifting projection (232) must be within the horizontal guide groove (222), so that the lifting member (220) is raised and lowered in proportion to the height of the lifting projection (232).

[0084] Here, the lifting projection (232) may be formed in the direction opposite to the adjustment projection (231) with respect to the rotation axis (2423) in the direction adjustment cam (230). That is, when the adjustment projection (231) is located at the top, the lifting projection (232) may be mutually arranged to be located at the bottom.

[0085] A main shaft coupling part (223) is formed at the top of the lifting part (220). A coupling hole is formed in the main shaft coupling part (223), so that the main shaft (203) of the inclined plate (200) can be coupled through it.

[0086] A front axis mounting section (243) and a rear axis mounting section (244) are installed at the front and rear of the driving body (240). The front axis mounting section (243) and the rear axis mounting section (244) provide a space for mounting the front axis (204) and the rear axis (205) of the inclined plate (200).

[0087] The rear of the front axis mounting section (243) and the front of the rear axis mounting section (244) are open. A direction adjustment section (210) may be installed between the front axis mounting section (243) and the rear axis mounting section (244). The direction adjustment section (210) may include a front axis fixing section (211) that fixes the front axis (204) within the front axis mounting section (243), and a rear axis fixing section (212) that fixes the rear axis (205) within the rear axis mounting section (244).

[0088] A fixing groove (2111, 2121) for fixing the front axis (204) and the rear axis (205) may be formed in a horizontal direction in the front axis fixing part (211) and the rear axis fixing part (212). That is, when the front axis fixing part (211) moves forward in a horizontal direction relative to the front axis (204), the front axis (204) can be fixed and its position can be fixed. In addition, when the rear axis fixing part (212) moves backward in a horizontal direction relative to the rear axis (205), the rear axis (205) can be fixed and its position can be fixed.

[0089] A spacing member (213) is disposed between the front axis fixing member (211) and the rear axis fixing member (212) to maintain the spacing between them. The spacing member (213) has a curved rod shape that is convex upward. On its lower side, a direction adjustment piece (214) is formed with a groove having a shape corresponding to the adjustment projection (231) of the direction adjustment cam (230). The direction adjustment piece (214) includes two tip portions with a concave groove formed in the center. That is, the spacing member (213) can be divided into three concave zones by the two tip portions.

[0090] We will now explain the principle by which the inclination direction of the inclined plate (200) is adjusted in the moving module (120) having the aforementioned structure.

[0091] Referring to FIGS. 8 to 11, the case in which the inclined plate (200) of the moving module (120) is in a horizontal state (see FIG. 8 (a) and FIG. 9), the case in which it has a backward inclination (see FIG. 8 (b) and FIG. 10), and the case in which it has a forward inclination (see FIG. 8 (c) and FIG. 11) are illustrated.

[0092] When the inclined plate (200) is in a horizontal state, it may be in a basic state where the acupressure bed (1) is not operating. In this case, the control unit (not shown) can drive the drive motor (2421) through a control signal so that the adjustment projection (231) of the direction adjustment cam (230) is positioned at the top. In this case, the adjustment projection (231) is placed in the middle concave area among the three concave areas of the direction adjustment unit (210), so that the direction adjustment unit (210) is positioned in the middle without moving forward or backward.

[0093] Additionally, since the adjustment projection (231) is located at the top, the lifting projection (232) is located at the bottom. As the lifting part (220), which rises and falls in correspondence with the height of the lifting projection (232), also descends to the lowest point, the inclined plate (200) maintains a balanced horizontal state in the front-rear direction.

[0094] Next, we will describe the case where the inclined plate (200) has a rearward inclination. Referring to FIG. 10, the control unit drives the drive motor (2421) through a control signal to rotate the direction adjustment cam (230) and causes the adjustment projection (231) of the direction adjustment cam (230) to move toward the rear. In this case, the adjustment projection (231) is positioned within the rearward concave area among the three concave areas of the direction adjustment unit (210), and the direction adjustment unit (210) moves forward.

[0095] As the direction adjustment unit (210) moves forward, the front axis fixing unit (211) moves forward within the front axis mounting unit (243) and inserts the front axis (204) of the inclined plate (200) into the fixing groove (2111), thereby fixing the position of the front axis (204).

[0096] Then, the height of the lifting projection (232) is raised by the rotation of the direction adjustment cam (230), and accordingly, the lifting section (220) is also raised. When the lifting section (220) is raised, the main shaft (203) of the inclined plate (200) coupled to the lifting section (220) is raised. In this case, the front shaft (204) is fixed and the rear shaft (205) is released from fixation, so that hinge rotation is performed with the fixed front shaft (204) as the hinge axis. Thus, the inclined plate (200) can have a rearward inclination where the rear is high and the front is low. The height of the lifting section (220) can be adjusted according to the degree of rotation of the direction adjustment cam (230), and the angle of inclination of the rearward inclination can be adjusted according to the height of the lifting section (220).

[0097] Next, we will explain the case where the inclined plate (200) has a forward and backward inclination. Referring to FIG. 11, the control unit drives the drive motor (2421) through a control signal to rotate the direction adjustment cam (230) and causes the adjustment projection (231) of the direction adjustment cam (230) to move forward. In this case, the adjustment projection (231) is positioned within the forward concave area among the three concave areas of the direction adjustment unit (210), and the direction adjustment unit (210) moves backward.

[0098] As the direction adjustment unit (210) moves backward, the rear shaft fixing unit (212) moves backward within the rear shaft mounting unit (244) and inserts the rear shaft (205) of the inclined plate (200) into the fixing groove (2121), thereby fixing the position of the rear shaft (205).

[0099] Then, the height of the lifting projection (232) is raised by the rotation of the direction adjustment cam (230), and accordingly, the lifting section (220) is also raised. When the lifting section (220) is raised, the main shaft (203) of the inclined plate (200) coupled to the lifting section (220) is raised. In this case, the rear shaft (205) is fixed and the front shaft (204) is released from fixation, so that hinge rotation is performed with the fixed rear shaft (205) as the hinge axis. Thus, the inclined plate (200) can have a front-to-back slope with the front being higher and the rear being lower. The height of the lifting section (220) can be adjusted according to the degree of rotation of the direction adjustment cam (230), and the angle of inclination of the front-to-back slope can be adjusted according to the height of the lifting section (220).

[0100] Referring to FIG. 12, the direction of inclination can be adjusted according to the direction of movement of the moving module (120).

[0101] As illustrated in FIG. 12 (a), when the moving module (120) moves from front to back, the direction of inclination can be adjusted so that the front is higher and the rear is lower (see FIG. 11). As the moving module (120) having an inclined plate (200) with an inclined front-to-back slope moves, acupressure can be performed by the acupressure rod (112) sequentially moving up along the inclined plate (200) and then coming down due to its own weight.

[0102] As illustrated in FIG. 12 (b), when the moving module (120) moves from the rear to the front, the direction of the incline can be adjusted so that it has a rearward slope that is higher at the rear and lower at the front (see FIG. 10). As the moving module (120) having the incline plate (200) of the rearward slope moves, the acupressure rod (112) can perform a motion of being pushed up along the incline plate (200) sequentially and then coming down by its own weight, thereby performing acupressure.

[0103] Even if the inclined plate (200) of the moving module (120) has a forward-backward inclination or a backward-forward inclination, the acupressure rod (112) does not fall immediately from the highest point due to the forward curve (201) or the rear curve (202), but falls after being supported by the curve to some extent, thereby delaying the stage where the pressure of the acupressure rod (112) disappears due to the movement of the moving module (120) and improving the user's sense of use.

[0104] The method for controlling the acupressure bed and the method for adjusting the inclination direction of the movement module, performed by the aforementioned control unit, may also be implemented in the form of a recording medium containing computer-executable instructions, such as an application or program module executed by a computer. A computer-readable medium may be any available medium accessible by a computer and includes both volatile and non-volatile media, as well as removable and non-removable media. Additionally, a computer-readable medium may include a computer storage medium. A computer storage medium includes both volatile and non-volatile, removable and non-removable media implemented by any method or technique for storing information, such as computer-readable instructions, data structures, program modules, or other data.

[0105] The aforementioned method for controlling a pressure point massage bed and the method for adjusting the tilt direction of a movement module may be executed by an application basically installed on a terminal (which may include a program included in a platform or operating system, etc., basically installed on the terminal), or by an application (i.e., a program) directly installed by a user on a master terminal through an application provider server, such as an application store server, an application, or a web server related to the service. In this sense, the aforementioned method for controlling a pressure point massage bed and the method for adjusting the tilt direction of a movement module may be implemented as an application (i.e., a program) that is basically installed on the terminal or directly installed by a user, and may be recorded on a computer-readable recording medium such as a terminal.

[0106] FIG. 13 is a drawing showing a movable acupressure bed according to one embodiment of the present invention.

[0107] Figure 13 (a) shows a massage bed in a moving state, and (b) shows a massage bed in a bed state.

[0108] The movable acupressure bed (300) may include a main body (310) on which the aforementioned acupressure part (100) is installed.

[0109] A handle (311) is installed on the front of the main body (310), and a wheel (312) is installed on the bottom of the main body (310), so that the user can easily move the movable acupressure bed (300) to a desired location.

[0110] A cover (313) is provided on the main body (310), so that the pressure part (100) is not exposed to the outside when moving, thereby preventing the entry of foreign substances such as dust.

[0111] A detachable movable footboard (320) may be installed at the rear of the main body (310). The movable footboard (320) is mounted at the rear of the main body (310) in a moving state and can be moved together.

[0112] In bed mode, the cover (313) is separated from the rear of the main body (310) and seated between the main body (310) and the cover (313), so that the cover (313) can be utilized as part of the bed that supports the user's buttocks and legs.

[0113] Through a movable acupressure bed (300) like the present embodiment, the user can easily switch the state of the bed to one of (a) and (b), move it to a desired position in the movable state (a), and receive an optimal acupressure service in the bed state (b).

[0114] In the movable acupressure bed (300) according to the present embodiment, the control unit controls the movement of the movement module (120) using the following techniques.

[0115] First, there are techniques for calculating travel distance and processing commands. Acceleration and deceleration phases can be implemented by generating a position profile. A duty modulator can be designed to map the input unit voltage (V) to the motor drive's PWM interface. Pulses can be converted to angles through encoder readout processing.

[0116] Next, there is a technique to improve positional accuracy. Positional accuracy can be improved by using the homing technique during power-on.

[0117] In addition, there is a constant pressure control technique. This technique is designed to apply uniform pressure regardless of the user's body curvature depth (height). Load can be analyzed for constant pressure control.

[0118] Although the present invention has been described above with reference to embodiments thereof, those skilled in the art will understand that various modifications and changes can be made to the present invention without departing from the spirit and scope of the invention as described in the claims below.
