Description

[Technical field]

[0001] The present invention relates to a massage device having an improved independently moving leg massage unit, and more particularly to a massage device capable of preventing safety accidents by providing a safety sensor module between the leg massage units. [Background technology]

[0002] Massage is a medical auxiliary therapy that adjusts the subject's physical condition and improves blood circulation by applying various forms of mechanical stimulation to a part of the subject's body, such as kneading, pushing, pulling, tapping, or moving the part of the body, thereby relieving the subject's fatigue.

[0003] The increase in the demand for massage has led to an increase in the demand for massage devices that provide an artificial massage function due to economic and time reasons. That is, with the increase in the demand to relieve fatigue or stress by relieving stiff muscles through massage, various massage devices that are time- and cost-efficient are available on the market.

[0004] In recent years, people have become more and more concerned about their health, and massage devices have changed from simply providing massage functions to electronic devices providing various additional functions and / or medical functions, which has led to ongoing research into methods for efficiently controlling massage devices.

[0005] In particular, since the parts of the body that each user desires to receive massage and the stimulations that each user desires may differ, users are increasingly researching devices and methods for providing massages in a form that is optimized for each user.

[0006] As an example of such a massage device, Patent Document 1: Korean Patent Publication No. 10-2020-0100561 discloses an example of a massage device that is divided into a first leg massage section that accommodates the right leg and a second leg massage section that accommodates the left leg, and the first leg massage section and the second leg massage section behave independently.

[0007] Meanwhile, in the case of the leg massage units that move independently, there is a problem that a part of the user's body may be caught between the leg massage units due to the independent movement of the leg massage units, which may lead to a safety accident.

[0008] Therefore, there is a need for research into a massage device that can prevent safety accidents while having an independently operating leg massage unit. [Prior art documents] [Patent documents]

[0060] The leg massage unit 1300 includes an accommodation space for accommodating the user's legs and can provide a leg massage to the user by massaging at least a portion of the user's legs. For example, the leg massage unit 1300 can include a calf massage unit for massaging the user's calves and / or a foot massage unit for massaging the user's feet.

[0061] The length of the leg massage unit 1300 can be adjusted according to the physical characteristics of the user. For example, when a tall user uses the massage device 1000, the length of the leg massage unit 1300 needs to be long because the length of the calf is long. Also, when a short user uses the massage device 1000, the length of the calf is short so the length of the leg massage unit 1300 needs to be short. Thus, the leg massage unit 1300 can provide a customized leg massage according to the height of the user. According to an embodiment of the present invention, the user can control the massage device 1000 using the massage device control device 2000. The massage device control device 2000 can be connected to the massage device 1000 through wired communication and / or wireless communication.

[0063] FIG. 2 is a diagram for explaining the massage device according to an embodiment.

[0064] According to one embodiment of the present disclosure, the main frame 1130 may include an upper frame 1131 on which the massage module 1110 is mounted, and a base frame 1132 that supports the upper frame 1131 .

[0065] A rack gear 1131a may be provided on at least a portion of the upper frame 1131. The rack gear 1131a is a member for guiding the upward and downward movement of the massage module 1110, and may include a plurality of valleys and a plurality of peaks.

[0066] According to an embodiment of the present disclosure, the rack gears 1131a may be provided on both sides of the upper frame 1131 in a form facing each other, and the massage module 1110 may move along the rack gears 1131a.

[0067] In Fig. 2, the rack gear 1131a is formed in the up-down direction, but is not limited thereto. The rack gear 1131a may include a front-rear rack gear and an up-down rack gear. In the present disclosure, the front-rear direction means a direction from the massage module 100 to the user or a direction from the user to the massage module 100, and may mean the X-axis direction based on Fig. 2.

[0068] The massage module 1110 may include a gear that meshes with the rack gear 1131a. More specifically, the massage module 1110 may include gears that mesh with the front and rear rack gears and the up and down rack gears. The gears are rotated by an actuator provided in the massage module 1110, so that the massage module 1110 can move forward, backward, upward, or downward.

[0069] The further forward the massage module 1110 moves, the stronger the massage intensity may be, and the further backward the massage module 1110 moves, the weaker the massage intensity may be.

[0070] The rack gear 1131a may be made of a metal material or a plastic material, for example, iron, steel, alloy, reinforced plastic, melamine resin, phenolic resin, etc., but is not limited thereto.

[0071] The upper frame 1131 may be implemented in various shapes, for example, the upper frame 1131 may be classified into an S frame, an L frame, an S&L frame, and a double S&L frame according to the shape, but is not limited thereto.

[0072] The S frame refers to a frame in which at least a portion of the upper frame 1131 is bent into an "S" shape. The L frame refers to a frame in which at least a portion of the upper frame 1131 is bent into an "L" shape, the S&L frame refers to a frame in which both an "S" shape and an "L" shape are bent, and the double S&L frame refers to a frame in which both an "L" shape and two parts are bent into an "S" shape.

[0073] The base frame 1132 refers to a portion that supports the upper frame 1131 and is in contact with the ground. The base frame 1132 may include a base upper frame 1132a and a base lower frame 1132b.

[0074] The base upper frame 1132a can support the upper frame 1131, and the base lower frame 1132b can be in contact with the ground. Also, the base upper frame 1132a can be positioned so as to be in contact with the base lower frame 1132b.

[0075] According to one embodiment of the present disclosure, the base upper frame 1132a can move along the base lower frame 1132b. For example, the base upper frame 1132a can slide forward or backward along the base lower frame 1132b. In this case, the upper frame 1131 is connected to the base upper frame 1132a and can move with the movement of the base upper frame 1132a.

[0076] For example, when the base upper frame 1132a moves forward, the upper frame 1131 can move forward therewith, and when the base upper frame 1132a moves backward, the upper frame 1131 can move backward therewith, thereby allowing the body massage part 1000 to slide.

[0077] To allow the base upper frame 1132a to move, a moving wheel may be provided on the lower part of the base upper frame 1132a. Also, a guide member capable of guiding the moving wheel may be provided on the upper part of the base lower frame 1132b. The moving wheel provided on the base upper frame 1132a moves along the guide member provided on the base lower frame 1132b, thereby allowing the base upper frame 1132a to move forward or backward.

[0176] When the side rotation member 1552 rotates downward and the end portion comes into contact with the side fixing member 1551, the side rotation member 1552 can be fastened to the side fixing member 1551 by the fastening member.

[0177] The process of fastening the second side bush 1322 to the second side support bracket 1550b is similar to the process of fastening the first side bush 1312 to the first side support bracket 1550a described above.

[0178] As described above, since the center bush and the side bush can be fixed by fastening them to the center support bracket 1530 and the side support bracket 1550, the leg massage unit 1300 can be easily connected to the body massage unit 1100.

[0179] FIG. 15 is an enlarged view of portion D of FIG. 7, FIG. 16 is a view showing a disassembled state of a safety sensor module according to one embodiment of the present invention, and FIG. 17 is a view showing another embodiment of a safety sensor module according to one embodiment of the present invention.

[0180] 15 and 16, a massage device 1000 according to one embodiment of the present invention can include a safety sensor module 1500.

[0181] The safety sensor module 1500 may be provided on the leg connecting frame 113lb. For example, the safety sensor module 1500 may be provided on a portion of the leg connecting frame 113lb corresponding to the space between the first leg massage portion 1310 and the second leg massage portion 1330.

[0182] When an external force is applied, the safety sensor module 1500 can control the driving of at least one of the first leg massage unit 1310 and the second leg massage unit 1330. For example, when an external force is applied, the safety sensor module 1500 can stop the rotation operation of at least one of the first leg massage unit 1310 and the second leg massage unit 1330. In addition, when an external force is applied, the safety sensor module 1500 can rotate the first leg massage unit 1310 and the second leg massage unit 1330 by a predetermined angle in a direction opposite to a direction in which at least one of the first leg massage unit 1310 and the second leg massage unit 1330 rotates.

The vibration elements may be arranged in areas adjacent to the user's body within the entire area of ​​the leg massage portion 1300 (eg, areas corresponding to the soles of the feet and areas corresponding to the calves, etc.).

[0184] Therefore, the safety sensor module 1500 can prevent a safety accident that may occur when the user's body is caught between the leg massage parts 1300. In addition, the safety sensor module 1500 can prevent damage or malfunction of the device that may occur when an object falls between the leg massage parts 1300.

[0185] The safety sensor module 1500 may include a sensor bracket 1510 , a sensor 1520 , a center support bracket 1530 , and a pressure plate 1540 .

[0186] The sensor bracket 1510 may be provided to support the sensor 1520. The sensor bracket 1510 may be coupled to the leg connection frame 113lb. For example, the sensor bracket 1510 may be coupled to the leg connection frame 113lb by welding or by a separate fastening member. The method of coupling the sensor bracket 1510 to the leg connection frame 113lb may be replaced by various methods commonly used in the technical field to which the present invention belongs.

[0187] The sensor bracket 1510 may include a protrusion 1511 and a bent portion 1512. One side of the protrusion 1511 may be coupled to the leg connection frame 113lb, and the other side may protrude forward. The bent portion 1512 may be bent downward at the other protruding end of the protrusion 1511. Thus, the sensor bracket 1510 may be provided in an L-shape as a whole. The bent portion 1512 may be provided with a sensor coupling hole 1512a.

[0188] The sensor 1520 may be coupled to the sensor bracket 1510. For example, the sensor 1520 may be coupled to the bent portion 1512 of the sensor bracket 1510. At this time, at least a portion of the sensor 1520 may be provided to pass through the sensor coupling hole 1512a. Therefore, at least a portion of the sensor 1520 may protrude forward of the bent portion 1512.

[0189] The sensor 1520 can recognize the contact of the pressing plate 1540. For example, when an external force is applied to the pressing plate 1540 to rotate the pressing plate 1540, the pressing plate 1540 can come into contact with the sensor 1520. When the pressing plate 1540 is contacted, the sensor 1520 can transmit the information to the control unit 1400. When the control unit 1400 receives the information that the pressing plate 1540 is contacted from the sensor 1520, the control unit 1400 can control the driving of at least one of the first leg massage unit 1310 and the second leg massage unit 1330 as described above. In addition, the control unit 1400 can drive an alarm unit to send a warning signal to the user.

[0190] The sensor 1520 may be a sensor using a measuring means such as pressure, potential, optics, etc. For example, the sensor 1520 may include a sensor housing 1521, a contact portion 1522 provided in the sensor housing 1521 and detecting contact with the pressing plate 1540, a fastening portion 1523 for fastening to the sensor bracket 1510, and an electrode terminal 1524 for electrical connection with an external device.

[0191] When pressure is applied by the pressing plate 1540, the contact portion 1522 may slide toward the inside of the sensor housing 1521. To this end, a separate elastic member may be provided inside the sensor housing 1521 to apply an elastic force to the contact portion 1522. When the contact portion 1522 receives pressure and slides toward the inside of the sensor housing 1521, the sensor 1520 may transmit a signal to the control unit 1400. As a result, the control unit 1400 may control the operation of at least one of the first leg massage unit 1310 and the second leg massage unit 1330, as described above, or may transmit a warning signal to the user through the alarm unit.

[0192] The fastening portion 1523 may be provided for coupling with the sensor bracket 1510. The fastening portion 1523 may be provided with a material having elasticity, and may be inserted into the sensor coupling hole 1512a formed in the sensor bracket 1510 when the sensor 1520 is coupled. The fastening portion 1523 may include an inclined surface so as to be easily inserted into the sensor coupling hole 1512a. The inclined surface may be provided such that the distance from the sensor housing 1521 increases from the rear to the front of the sensor 1520 when one side end is fixed to the sensor housing 1521. In addition, the other side end of the inclined surface may be provided with a flat surface for easy contact with the sensor coupling hole 152la. The flat surface may contact the inner surface of the sensor coupling hole 152la. The fastening portion 1523 may be bent toward the sensor housing 1521 when held by a user. Thus, if the sensor 1520 needs to be separated, a user can grasp the fastening portion 1523 to separate the sensor 1520 from the sensor bracket 1510.

[0193] In addition, the sensor 1520 may be replaced with various sensors commonly used in the technical field to which the present invention pertains, so long as they can recognize the rotation or contact of the pressing plate 1540. For example, the sensor 1520 may be at least one of a pressure sensor, an infrared sensor, an LED sensor, a touch sensor, and an electrode sensor.

[0194] The center support bracket 1530 may be disposed on both sides of the sensor bracket 1510. The center support bracket 1530 may be manufactured as a separate member from the sensor bracket 1510, or may be manufactured integrally with the sensor bracket 1510. Alternatively, the center support bracket 1530 and the sensor bracket 1510 may be manufactured as separate members, and then the center support bracket 1530 and the sensor bracket 1510 may be combined by a method such as welding. The method of combining the center support bracket 1530 and the sensor bracket 1510 may be replaced by various methods commonly used in the technical field to which the present invention belongs. A pressing plate 1540 may be rotatably connected to the center support bracket 1530. The sensor bracket 1510 may include a center fixing member 1531 and a center rotating member 1532.

[0195] The center fixing member 1531 may include, for example, a base portion 1531c and side portions 1531d protruding upward from both sides of the base portion 1531c. The base portion 1531c and the side portions 1531d may be formed by bending a single member. However, the base portion 1531c and the side portions 1531d may also be made of separate members and then joined together.

[0196] The base 1531c may form a bottom surface of the center fixing member 1531. At least one stopper 153le may be provided on the base 1531c. The stopper 153le may limit an angle at which the pressing plate 1540 rotates in a direction away from the sensor 1520. The stopper 153le may penetrate the base 1531c and have an end protruding downward from the base 1531c. When a single stopper 153le is provided, the stopper 153le may be disposed in a central region of the base 1531c, and when a plurality of stoppers 153le are provided, the stopper 153le may be disposed in at least one of the central region and both side regions of the base 1531c.

[0197] The position and structure of the stopper 153le can be changed in various ways as long as the rotation angle of the pressing plate 1540 can be limited. For example, the stopper 153le can be attached to the bottom surface of the base 1531c so that all the stoppers 1531e protrude downward from the base 1531c. The stopper 1531e may be manufactured integrally with the base 1531c. The stopper 1531e may be provided on the pressing plate 1540.

[0198] The side 1531d may include a leg connection frame insertion groove 1531d-1. The leg connection frame 1131b may be inserted and coupled into the leg connection frame insertion groove 1531d-1. The leg connection frame insertion groove 1531d-l may be formed by cutting out one end of the side 153ld facing the leg connection frame 113lb. The leg connection frame insertion groove 1531d-l may be formed in a shape such that an inner surface thereof is fitted into an outer surface of the leg connection frame 113lb. When the leg connection frame 113lb is inserted into the leg connection frame insertion groove 1531d-l, a portion where the side 1531d and the leg connection frame 113lb come into contact with each other may be welded. However, a method for coupling the side 153ld and the leg connection frame 113lb may be replaced by a method commonly used in the technical field to which the present invention belongs.

[0199] The side portion 1531d may include a center rotation member insertion hole 1531d-2. The center rotation member 1532 may be rotatably hinged to the center rotation member insertion hole 1531d-2. The center rotation member insertion hole 1531d-2 may be provided at various positions on the side portion 1531d to allow the center rotation member 1532 to rotate on the upper portion of the side portion 1531d.

[0200] The side portion 1531d may include a pressure plate insertion hole 1531d-3. One side of the pressure plate 1540 may be rotatably hinged to the pressure plate insertion hole 1531d-3. The pressure plate insertion hole 1531d-3 may be provided at various positions on the side portion 1531d such that the other side of the pressure plate 1540 rotates upward (see FIG. 16) or downward (see FIG. 17) and comes into contact with the sensor 1520 when rotated beyond a preset angle. For example, the pressure plate insertion hole 1531d-3 may be provided on the front lower side (see FIG. 16) or the front upper side (see FIG. 17) of the side portion 1531d.

[0201] One of the sides 1531d protruding from both sides of the base 1531c may be provided with a fixing piece 1531d-4 bent toward the other side 1531d. However, the fixing piece 1531d-4 may be made of a separate member and coupled to both sides 1531d. When the center rotation member 1532 rotates and an end of the center rotation member 1532 comes into contact with the fixing piece 1531d-4, the end of the center rotation member 1532 and the fixing piece 1531d-4 may be fastened by a fastening member.

[0202] The side portion 1531d may include a center bush receiving groove 1531d-5. The center bushes 1311 and 1321 may be rotatably seated in the center bush receiving groove 1531d-5. The center bush receiving groove 1531d-5 may be formed by, for example, cutting out an upper end portion of the side portion 1531d.

[0203] The center rotating member 1532 may be rotatably hinged to the side portion 1531d. The center rotating member 1532 may include a center bush fixing groove 1532d. When the center rotating member 1532 rotates and is engaged with the fixing piece 1531d-4 of the side portion 1531d, the center bush fixing groove 1532d may rotatably support the center bushes 1311 and 1321 together with the center bush receiving groove 1531d-5.

[0204] The pressure plate 1540 may be hinged to the center support bracket 1531d so as to be rotatable. The pressure plate 1540 may include an elastic member 1541. The elastic member 1541 may apply an elastic force to the pressure plate 1540 so that a free end of the pressure plate 1540 rotates in a direction away from the sensor 1520. The elastic member 1541 may be made of various members capable of applying an elastic force to the pressure plate 1540. As an example, the elastic member 1541 may be made of a torsion spring. When the elastic member 1541 is made of a torsion spring, both side ends of the torsion spring may contact at least one of the pressure plate 1540 and the center support bracket 1530 when the pressure plate 1540 rotates.

[0205] The elastic member 1541 can prevent the pressure plate 1540 from rotating simply due to the user's body or other object coming into contact with the pressure plate 1540 in a situation where the user's body or other object is not caught between the leg massage units 1300 or between the leg massage unit 1300 and the body massage unit 1100.

[0206] The pressure plate 1540 may rotate and come into contact with the sensor 1520. For example, when an external force greater than or equal to the elastic force of the elastic member 1541 is applied to the pressure plate 1540, the pressure plate 1540 may rotate and come into contact with the sensor 1520.

[0207] 18a and 18b are diagrams illustrating a process in which the safety sensor module according to an embodiment of the present invention is operated.

[0208] 18a, one end of the pressing plate 1540 may be spaced apart from the sensor 1520 and the other end may contact the stopper 1531e due to the elastic force of the elastic member 1541. Since the elastic force is continuously acting on the pressing plate 1540, one end of the pressing plate 1540 may not contact the sensor 1520 unless a predetermined external force is applied for a predetermined time.

[0209] 18b, when at least one of the leg massage unit 1300 and the body massage unit 1100 rotates while the user's body is sandwiched between the leg massage unit 1300 and / or between the leg massage unit 1300 and the body massage unit 1100, an external force F greater than the elastic force of the elastic member 1541 may be applied to the pressing plate 1540. Also, unless the sandwiched state is released, the external force F continues to act on the pressing plate 1540. In this case, the pressing plate 1540 may rotate and one end of the pressing plate may come into contact with the sensor 152. If the pressing plate 1540 is contacted, the sensor 1520 may transmit the corresponding information to the control unit 1400. If the control unit 1400 receives information from the sensor unit 1520 that the pressing plate 1540 is contacted, the control unit 1400 may control the operation of at least one of the first leg massage unit 1310, the second leg massage unit 1330, and the body massage unit 1100, or may activate an alarm unit. Therefore, a safety accident that may occur when the user's body is caught between the leg massage parts 1300 and / or between the leg massage part 1300 and the body massage part 1100 can be prevented.

[0210] In addition, it is possible to prevent malfunctions and damages of the device that may occur when objects other than the user's body are caught between the leg massage unit 1300 or between the leg massage unit 1300 and the body massage unit 1100.

[0211] Although the technical concept of the present invention has been described above with reference to the accompanying drawings, this is merely an illustrative description of a preferred embodiment of the present invention and is not intended to limit the present invention. In addition, it is obvious that anyone having ordinary skill in the art to which the present invention pertains can make various modifications and imitation of the present invention within the scope of the technical concept of the present invention.

[0212] In addition, the configuration and functions of the massage device in this specification can be expanded and applied to various (wearable) healthcare devices that can provide healthcare functions (e.g., kneading / massaging function, biosignal measurement function, etc.). Therefore, it goes without saying that the "massage device" in this specification can be described as a "(wearable) healthcare device" instead.
