Description

Technical Field

[0001] The present invention relates to a foot massaging device, and more particularly, to a foot massaging device including a plurality of rollers different from each other to perform massage corresponding to a user's foot shape. Background Art

[0002] Massage refers to a medical auxiliary therapy that regulates the body changes of the massage object, helps blood circulation and relieves fatigue of the massage object by applying various forms of mechanical stimulation to the body parts of the massage object, such as kneading, pressing, stretching, patting or body movements.

[0003] Due to economic conditions and time reasons, the demand for massage devices or massagers that provide manual massage functions has increased. That is, as the demand for relaxing tense muscles and eliminating fatigue or stress through massage has increased, various massage devices that are efficient in terms of time and cost have been introduced.

[0004] Recently, people's concern for health has increased, and massage devices have changed from simply providing a massage function to electronic devices providing a variety of additional functions and / or medical functions, and thus, research on methods of effectively controlling massage devices is still ongoing.

[0005] In particular, since the parts that each user wants to receive massage and the desired stimulation, etc. may be different, user demands for devices and methods that provide the best form of massage for each user are increasing.

[0006] In addition, the multiple acupressure protrusions of the conventional foot massager are all formed in the same shape and are all arranged at the same spacing. Therefore, even if the multiple acupressure protrusions apply pressure to the sole of the user's foot while the roller rotates, the sole of the user's foot will only receive an overall uniform pressure, and there is a problem that the specific area that needs to be massaged cannot be massaged.

[0007] In addition, due to the plurality of acupressure protrusions located at the foot massaging portion, when the user sits on or leaves the massage device, there is a problem that excessive weight may be applied to the user's feet supporting the acupressure protrusions.

[0156] The control unit 1400 determines whether the user's foot is placed inside the frame 1340, and can determine the driving force of the driving unit 2600 in accordance with the user's request. In addition, when the massage program ends or the user leaves the massage device, each of the rollers 2100, 2200, 2300 can be controlled so that the position of each roller 2100, 2200, 2300 where the protrusion is not provided faces the user's foot. More preferably, the rotation amount of the first roller 2100 can be controlled by applying the power of the driving unit 2600 so that the first main protrusion 2110 located on the first roller 2100 does not face the user's foot.

[0157] In one embodiment of the present invention, the control unit 1400 is configured to control the position of the first roller 2100 when the user leaves the massage device or the massage program ends, so that the position of the protrusion located on the first roller 2100 does not face the user's foot. This is for controlling the position of the highest protrusion among the multiple protrusions located on each roller 2100, 2200, 2300, in order to prevent excessive load from being applied to the user's foot when the user leaves the massage device, thereby causing pain.

[0158] like Figure 8 As shown, the first roller portion 2100 includes a first main protrusion 2110 having the highest shape, and may further include two first auxiliary protrusions 2120 having an angle of 90 degrees with the first main protrusion 2110 based on the central axis of the first roller portion 2100 .

[0159] In addition, the second roller portion 2200 is located at the front end of the first roller portion 2100 and includes two second protrusions 2210 formed to face each other with respect to the central axis of the second roller portion 2200. Furthermore, the third roller portion 2300 is located at the rear end of the first roller portion 2100 and includes third protrusions 2310 alternately arranged at both ends of the rotation axis of the third roller portion 2300 in the longitudinal direction.

[0161] The fixing portion 1341 located at the rear end of the frame 1340 has a shape that protrudes toward the upper end based on the lower surface of the frame 1340. Further, the fixing portion 1341 can be formed in a hollow form so that the cover portion 1350 can be inserted. The third roller portion 2300 adjacent to the fixing portion 1341 includes a third protruding portion 2310 located in an area that does not interfere with the fixing portion 1341. The third protruding portion 2310 is located at both ends of the cylindrical rotating shaft of the third roller portion 2300 in the longitudinal direction. With the protruding portion located at one end as a reference, the protruding portion located at the other end can be configured to have a predetermined angle with the protruding portion located at one end on the central axis of the third roller portion 2300. Further, the protruding portions located at both ends of the third roller portion 2300 can include two protruding areas so that the protruding portions located at the same ends face each other.

[0162] Thus, the third roller portion 2300 is configured such that its protrusion is not located in a region adjacent to the fixing portion 1341 , and protrusions having different angles are located at both ends of the third roller portion 2300 at intervals of 180 degrees with respect to the third roller portion 2300 .

[0163] As an embodiment of the present invention, Fig. 9 A top view of massage unit 2000 is shown with the left foot placed.

[0164] As shown in the figure, with the center portion A of the placement portion as a reference, the second roller portion 2200 is located at the front end, the third roller portion 2300 is located at the rear end, and the first roller portion 2100 is located between the second roller portion 2200 and the third roller portion 2300. The first main protrusion 2110 located at the first roller portion 2100 is configured to be arranged eccentrically toward the inner side of the user's foot with the center portion A in the length direction of the placement portion as a reference. That is, the first main protrusion 2110 can be configured to correspond to a position on the back of the user's foot where the arch is relatively large. As an embodiment of the present invention, the center portion A of the placement portion can be interpreted as the meaning that it corresponds to the center portion A of the placement portion when the user's foot is introduced into the placement portion. Further, the center portion A of the placement portion can refer to the center with the width of the position where the arch of the user's foot is formed as a reference.

[0165] The second protrusion 2210 of the second roller 2200 may be formed in an area corresponding to the front outer side of the user's foot. More preferably, the area corresponding to the little toe of the user's foot may include second protrusions 2210 spaced 180 degrees apart from each other based on the central axis of the second roller 2200.

[0166] The third roller 2300 may include third protruding portions 2310 at both ends of the third roller 2300 in the width direction that do not interfere with the fixing portion 1341, and the third protruding portions 2310 arranged to be spaced apart from each other may rotate by a predetermined angle based on the rotation axis of the third roller 2300. In addition, two protruding areas of the third protruding portion 2310 located at one end and the other end of the third roller 2300 may be arranged to face each other based on the third roller 2300. Therefore, the third protruding portion 2310 may include two protruding areas located at one end of the third roller 2300 and two protruding areas located at the other end.

[0167] As an embodiment of the present invention, FIG. 10A to FIG. 10B The first roller portion 2100 is shown in FIG.

[0168] like Fig. 10A As shown, the first roller portion 2100 includes: a first main protrusion 2110 protruding at one side; and a first auxiliary protrusion 2120 arranged to face each other in a perpendicular manner with the first main protrusion 2110 as a reference.

[0169] In one embodiment of the present invention, the first main protrusion 2110 is configured to have a height of h from a tangent point extending perpendicular to the central axis of the first roller portion 2100. The first secondary protrusion 2120 is arranged perpendicularly to the first main protrusion 2110 with the central axis of the first roller portion 2100 as a reference, and the first secondary protrusion 2120 is configured to have a lower height than the protrusion height h of the first main protrusion 2110. The first secondary protrusion 2120 may be configured to have a height of 0.6h to 0.75h compared to the protrusion height of the first main protrusion 2110. More preferably, the two first secondary protrusions 2120 are arranged facing each other, so as to have an angle of 180 degrees with respect to each other with the first roller portion 2100 as a reference, and may include a first main protrusion 2110 located between the two first secondary protrusions 2120.

[0170] Here, the height refers to a value obtained by subtracting the radius of the roller part 2100 , 2200 , 2300 from the maximum protrusion distance of the protrusion from the central axis of the roller part 2100 , 2200 , 2300 .

[0171] Furthermore, if Fig. 10B As shown, the first auxiliary protrusion 2120 is located at the central portion A of the placement portion, and the first main protrusion 2110 is arranged eccentrically inward from the central portion A.

[0172] Right now, Fig. 10BThe first main protrusion 2110 of the second foot massaging part 1330 shown in FIG. 1 , which is located corresponding to the left foot of the user, has a center portion B deviated to the inside by a prescribed distance from a center portion A of the placement portion where the left foot of the user is inserted. That is, the first main protrusion 2110 is arranged in an eccentric manner so that the inner side of the foot having a relatively high arch faces the first main protrusion 2110 having the maximum height.

[0173] Further, the first main protrusion 2110 of the first foot massaging part 1310 corresponding to the right foot of the user may include the first main protrusion 2110 which is directed toward the right foot of the user. Fig. 10B The eccentricity direction of the first main protrusion 2110 disclosed in is opposite to that of the eccentricity direction of the first main protrusion 2110.

[0174] Furthermore, the first roller 2100 facing the first main protrusion 2110 has a surface without protrusions.
