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

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

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

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

[0005] In particular, since each user may have different desired massage areas and stimulations, there has been an increase in research activities by users into devices and methods that provide massages in a form optimized for each user.

[0006] As an example of such a massage device, Patent Document 1: Korean Patent Publication No. 1 0-2020-0100561 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 second leg massage section behave independently.

[0007] Meanwhile, in the case of independently moving leg massage units, there is a problem that a part of the user's body may be caught between the leg massage units due to the independently moving 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 moving leg massage unit. [Prior art documents] [Patent documents]

[0066] According to an embodiment of the present disclosure, 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 vertical direction, but this is not limited to this. 1 The "a" may include a rack gear in the forward-backward direction and a rack gear in the up-down direction. The "forward-backward direction" in this disclosure refers to the direction from the massage module 100 toward the user or the direction from the user toward the massage module 100, and may refer to 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, respectively. 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 can be, and the further backward the massage module 1110 moves, the weaker the massage intensity can 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 embodied 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 depending on 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 in an "S" shape, the L frame refers to a frame in which at least a portion of the upper frame 1131 is bent in 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 of an "S" shape are bent.

[0073] The base frame 1132 refers to a part that supports the upper frame 1131 and comes into 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.

The center rotation member 1532 may be rotatably hingedly coupled 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 top 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 so that the other side of the pressure plate 1540 can be rotated upward (see FIG. 16) or downward (see FIG. 17) and come into contact with the sensor 1520 when rotated beyond a predetermined angle. For example, the pressure plate insertion hole 1531d-3 may be provided on the front lower side (see FIG. 16) or front upper side (see FIG. 17) of the side portion 1531d.

[0201] One of the side portions 1531d protruding from both sides of the base 1531c may have a fixing piece 1531d-4 bent toward the other side portion 1531d. However, the fixing piece 1531d-4 may be made of a separate member and attached to both side portions 1531d. When the center rotation member 1532 rotates and its end contacts the fixing piece 1531d-4, the end of the center rotation member 1532 and the fixing piece 1531d 1 d-4 can be fastened together 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 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. The center rotating member 1532 may rotate to fix the side portion 1531d. 1 When the center bush fixing groove 1532d is coupled with the fixing piece 1531d-4 of the center bush 1311, 1321, the center bush fixing groove 1532d can rotatably support the center bushes 1311, 1321 together with the center bush receiving groove 1531d-5.

[0204] The pressure plate 1540 may be rotatably hinged to the center support bracket 1531d. 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 the free end of the pressure plate 1540 rotates in a direction away from the sensor 1520. The elastic member 1541 may be formed of various members capable of applying an elastic force to the pressure plate 1540. For example, the elastic member 1541 may be formed of a torsion spring. If the elastic member 1541 is formed of a torsion spring, both 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 pressing plate 1540 from rotating simply by contacting the user's body or other objects with the pressing plate 1540, provided that the user's body or other objects are 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 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 of operating a safety sensor module according to an embodiment of the present invention.

[0208] 18a, one end of the pressing plate 1540 can be positioned to be separated from the sensor 1520 and the other end can be brought into contact with the stopper 1531e due to the elastic force of the elastic member 1541. Because the elastic force is continuously acting on the pressing plate 1540, one end of the pressing plate 1540 may not be brought into contact with 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 pressure plate 1540. Furthermore, unless the sandwiched state is released, the external force F continues to act on the pressure plate 1540. In this case, the pressure plate 1540 rotates, and one end of the pressure plate 1540 may come into contact with the sensor 152. If the pressure plate 1540 comes into contact with the sensor 1520, the sensor 1520 may transmit corresponding information to the control unit 1400. When the control unit 1400 receives information from the sensor unit 1520 that the pressure plate 1540 has come into contact with the sensor 1520, 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 units 1300 and / or between the leg massage unit 1300 and the body massage unit 1100 can be prevented.

[0210] In addition, it is possible to prevent malfunction and damage to the device that may occur when an object other than the user's body gets 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 skilled 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 extended 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 substituted for the "(wearable) healthcare device."
