Description

TECHNICAL FIELD

[0001] The foot massage device according to the present application is a device for performing massage on a user's foot by rotating a plurality of rollers in a state in which the plurality of rollers are in contact with the user's foot. BACKGROUND

[0002] Massage refers to a medical auxiliary therapy for regulating a body change of a massage subject by applying various mechanical stimulations such as kneading, pressing, stretching, slapping, or moving a body to the partial body of the massage subject, and is helpful for blood circulation and relieving fatigue of the massage subject.

[0003] Due to economic situations and time, the demand for a massage device or a massager providing a manual massage function has increased. That is, as the demand for relaxing tense muscles and relieving fatigue or stress through massage increases, various massage devices efficient in terms of time and cost have been introduced.

[0004] Recently, people's interest in health has increased, and a massage device has changed from a simple massage function provider to an electronic device providing various additional functions and / or medical functions, and thus, research into a method of effectively controlling the massage device is still ongoing.

[0005] In particular, as the part to which each user wants to receive massage and the desired stimulation can be different, the user's demand for a device and a method of providing the best form of massage to each user is increasing.

[0006] In addition, the plurality of finger pressure protrusions of the conventional foot massager are all formed in the same shape and are all disposed at the same interval. Therefore, even in the case where the plurality of finger pressure protrusions press the sole of the user while the rollers are rotating, the sole of the user receives only overall uniform pressure, and there is a problem in that a specific area requiring massage cannot be massaged.

[0007] In addition, as the plurality of finger pressure protrusions are located at the foot massage part, when the user sits on or gets off the massage device, there is a problem in that excessive weight is applied to the user's foot supporting the finger pressure protrusions.

The rack gear, which serves as a member for guiding the up-and-down movement of the massage module 1110, can be constituted using a well-known rack gear including a plurality of valley portions and a plurality of ridge portions.

[0093] According to an embodiment of the present disclosure, the rack gear can be provided in a form of facing each other at both sides of the upper frame 1131, and the massage module 1110 can move along the rack gear.

[0094] The rack gear is formed in the up-and-down direction, but is not limited thereto. The rack gear can include a rack gear in the front-and-rear direction as well as a rack gear in the up-and-down direction. In the present disclosure, the front-and-rear direction can mean a direction from the massage module 1110 toward the user or from the user toward the massage module 1110, and the up-and-down direction can mean a direction from the user toward the massage module 1110 or from the massage module 1110 toward the user. Figure 2 The reference direction can mean the X-axis direction.

[0095] The massage module 1110 can include a gear engaged with the rack gear. More specifically, the massage module 1110 can include gears engaged with the rack gear in the front-and-rear direction and the rack gear in the up-and-down direction, respectively. The gears are rotated by an actuator provided to the massage module 1110, and the massage module 1110 can move forward, backward, upward, or downward.

[0096] As the massage module 1110 moves forward, the strength of the massage can increase. In addition, as the massage module 1110 moves backward, the strength of the massage can decrease.

[0097] The rack gear can be implemented by a metal material or a plastic material. For example, the rack gear 1112 can be implemented by iron, steel, an alloy, reinforced plastic, melamine resin, phenol resin, etc., but is not limited thereto.

[0098] The upper frame 1131 can be implemented in various shapes. For example, the upper frame 1131 can be classified into an S-frame, an L-frame, an S&L-frame, a double S&L-frame, according to a shape, but is not limited thereto.

[0101] The base upper frame 1132a can support the upper frame 1131, and the base lower frame 1132b can come into contact with the ground. In addition, the base upper frame 1132a can be disposed in a manner of being connected with the base lower frame 1132b.

[0102] According to an embodiment of the present disclosure, the base upper frame 1132a can be movable 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 with the base upper frame 1132a, and thus can move along with the movement of the base upper frame 1132a.

[0103] For example, when the base upper frame 1132a moves forward, the upper frame 1131 can also move forward, and when the base upper frame 1132a moves backward, the upper frame 1131 can also move backward. Thereby, it is possible to allow the sliding of the body massage part 1100.

[0104] In order to allow the movement of the base upper frame 1132a, a lower portion of the base upper frame 1132a can be provided with a moving wheel. In addition, an upper portion of the base lower frame 1132b can be provided with a guide member that can guide the moving wheel. The moving wheel provided in the base upper frame 1132a moves along the guide member provided in the base lower frame 1132b, and thus it is possible to allow the forward movement or the backward movement of the base upper frame 1132a.

[0105] According to another embodiment of the present disclosure, the massage device 1000 can not provide a sliding function, and in this case, the base frame 1132 can not be separated into an upper frame and a lower frame.
