9 is a diagram schematically illustrating a conventional side holder 2320'.

Referring to FIG. 9 , the side holder 2320 ′ used in the conventional massage device 100 ′ includes a plurality of components.

Specifically, the conventionally used side holder 2320' is made such that one component is inserted into the other component and coupled thereto. At this time, one configuration may be made of a synthetic resin, for example, it may be made of a lubricating plastic. In addition, the remaining components may be made of a metal material and, for example, may include iron (Fe).

Therefore, in the prior art, since the side holder 2320' has a plurality of components, there is a problem that a plurality of parts are required, and it is difficult to buffer the noise or vibration generated by the rotation of the leg massage unit 2000'. .

In order to solve this problem, the massage device 100 according to the present invention may include an improved side holder 2320 .

FIG. 10 is a view for explaining a cushioning action on both sides of the leg massage unit 2000 of FIG. 7 , and FIG. 11 is a view schematically illustrating a side holder 2320 according to an embodiment of the present invention. 12 is a view schematically illustrating the first elastic member 2350 of FIG. 8 .

10 and 11 , the side holder 2320 according to an embodiment of the present invention may be integrally formed.

Specifically, the side holder 2320 has a first extension 2321 formed to be inserted into the first shaft fixing member 1150 and one end of the first extension 2321 rather than the first extension 2321 . It may include a first engaging jaw portion 2322 formed with a large diameter.

The first extension 2321 may be a portion inserted into the first shaft fixing member 1150 . The first extension 2321 may be formed to extend to have a length, and thereby may be stably inserted into the first shaft fixing member 1150 .

The first stopping protrusion 2322 is a portion formed at one end of the first extension 2321 , and may be formed to have a larger diameter than the first extension 2321 to perform a stopper function. Accordingly, in the side holder 2320 , only a portion corresponding to the first extension 2321 can be inserted into the first shaft fixing member 1150 , and the first locking jaw 2322 is the first shaft fixing member 1150 . may not be inserted into

The side holder 2320 may include a first insertion hole 2323 . The first insertion hole 2323 may be a space into which the first shaft member 2310 is inserted. Specifically, the first insertion hole 2323 may be formed along the longitudinal direction of the first locking protrusion 2322 , and may be formed along the longitudinal direction up to a portion of the first extension part 2321 . That is, the first insertion hole 2323 may be formed to extend from the end of the first engaging protrusion 2322 to a portion corresponding to a portion of the first extension 2321 , and the end of the first extension 2321 . may be closed.

Accordingly, the first shaft member 2310 may be inserted into the side holder 2320 through the first locking jaw portion 2322 , and may not be inserted any more at a predetermined position of the first extension portion 2321 .

As an embodiment, the side holder 2320 may include a plurality of grooves formed along the outer surface. For example, a plurality of grooves may be formed on the surface of the first stopping protrusion 2322 .

Referring back to FIG. 11 , grooves may be formed on the surface of the first locking jaw part 2322 to form a plurality of rows along the outer surface, and a plurality of grooves included in each row may be formed to have a predetermined interval along the outer diameter. can Accordingly, a shape in which a plurality of ribs are formed is implemented on the surface of the first stopping protrusion 2322 . Also, the formed grooves may have the same width and length. Accordingly, the force applied to the side holder 2320 from the outside can be uniformly distributed.

Accordingly, the side holder 2320 may be manufactured to be lightweight, and as will be described later, the removal efficiency of vibration or noise generated by the operation of the leg massage unit 2000 may be improved.

As an embodiment, the side holder 2320 may be made of a synthetic resin, and as a specific embodiment, it may be made of a material including polyacetal (POM).

Accordingly, the side holder 2320 may have strong resistance to abrasion due to rotation of the leg massage unit 2000, secure high strength, and may be manufactured to be lightweight. In addition, since the side holder 2320 has self-lubrication, it is possible to have strong resistance to friction caused by the rotation of the leg massage unit 2000 .

To solve this, the first elastic member 2350 may be disposed inside the side holder 2320 . For example, the first elastic member 2350 may be disposed inside the first extension part 2321 of the side holder 2320 , and specifically, it may be disposed at the end of the first insertion hole 2323 . .

Accordingly, when the first shaft member 2310 moves in the axial direction or vibration or noise is generated by the rotation of the leg massage unit 2000 , the first elastic member 2350 is the first elastic member 2310 of the first shaft member 2310 . It can dampen movement.

The first elastic member 2350 may be formed of a material having elasticity, and may be formed in a form capable of contracting and expanding in a direction parallel to the moving direction of the first shaft member 2310 . Specifically, as shown in FIG. 12 , the first elastic member 2350 may be formed such that surfaces formed integrally form curved surfaces having different heights from each other. Accordingly, the first elastic member 2350 may be formed to have a thin overall thickness.

Therefore, when the first shaft member 2310 is inserted more deeply into the inside of the side holder 2320, the first elastic member 2350 is contracted while buffering the force into which the first shaft member 2310 is inserted. , this force can be offset by the elastic force.

In addition, since the side holder 2320 is disposed on both sides of the leg massage unit 2000, there is a limit that it cannot have a length of more than a certain amount, so that the first elastic member 2350 is formed to have a thin thickness as described above, thereby limiting the space. can overcome

It may include a second engaging jaw portion 2342 formed with a large diameter.

The second extension part 2341 may be a part connected to the second shaft fixing part. The second extension 2341 may be formed to extend to have a length, and thereby may be stably coupled to the second shaft fixing member 1170 .

The second stopping protrusion 2342 is a portion formed at both ends of the second extension portion 2341, respectively, and may be formed to have a larger diameter than the second extension portion 2341 to perform a stopper function. Accordingly, the center holder 2340 may not swing left and right while the second extension portion 2341 is connected to the second shaft fixing portion.

The center holder 2340 may include a second insertion hole 2343 . The second insertion hole 2343 may be a space for the second shaft member 2330 to be inserted. Specifically, the second insertion hole 2343 may be formed to penetrate the center holder 2340 in the longitudinal direction. Accordingly, the second shaft member 2330 may be easily inserted into both ends of the center holder 2340 .

As an embodiment, the center holder 2340 may include a plurality of grooves formed along the outer surface.

Accordingly, a shape in which a plurality of ribs are formed is implemented on the surface of the center holder 2340 .

As an embodiment, the plurality of grooves formed on the surface of the second stopping protrusion 2342 may have the same width and length. Accordingly, when a force is applied to the center holder 2340 from the outside, the applied force may be uniformly distributed.

In addition, the groove formed along the center line among the plurality of grooves formed on the surface of the second extension part 2341 may be formed to have a greater thickness than the remaining grooves. In addition, the grooves formed in the left and right portions with respect to the grooves formed along the center line may be formed to be symmetrical to each other.

Accordingly, the center holder 2340 can be manufactured to be lightweight, and vibration or noise generated by the operation of the leg massage unit 2000 can be easily removed.

As an embodiment, the center holder 2340 may be made of a synthetic resin, and as a specific embodiment, it may be made of a material including polyacetal (POM).

Accordingly, the center holder 2340 may have strong resistance to abrasion due to rotation of the leg massage unit 2000, secure high strength, and may be manufactured to be lightweight. In addition, since the center holder 2340 has self-lubrication, it is possible to have strong resistance to friction caused by the rotation of the leg massage unit 2000 . As a result, there is an effect that the durability of the center holder 2340 is improved.

As an optional embodiment, the center holder 2340 may include a glass fiber. For example, the center holder 2340 may be manufactured by an injection process, and glass fibers may be added to polyacetal during the injection process. As a specific embodiment, the glass fiber may be contained in 10% or more, preferably in an amount of 20 to 50%. Accordingly, the center holder 2340 may have improved corrosion resistance and insulation, and may have improved durability against heat or chemical action generated by friction.

Referring back to FIG. 13 , the center holder 2340 may further include a second elastic member 2360 disposed between the second shaft members 2330 inserted from both sides.

Specifically, when the leg massage unit 2000 rotates while the second shaft member 2330 is inserted into the center holder 2340 , the second shaft member 2330 vibrates in the center holder 2340 or in the axial direction. will move to Accordingly, such vibrations may be transmitted to the entire massage device 100 or noise may be generated. To solve this, the second elastic member 2360 may be disposed inside the center holder 2340 . For example, the second elastic member 2360 may be disposed inside the second extension part 2341 of the center holder 2340 .

Accordingly, when the second shaft member 2330 moves in the axial direction or vibration or noise is generated by the rotation of the leg massage unit 2000, the second elastic member 2360 is the second shaft member 2330 of the second shaft member 2330. It can dampen movement.

The second elastic member 2360 may be formed of a material having elasticity, and may be formed in a form capable of contracting and expanding in a direction parallel to the moving direction of the second shaft member 2330 . Specifically, the second elastic member 2360 may be formed in the shape of a spring as shown in FIG. 13 . As a result, the second elastic member 2360 can stably buffer the applied force even when the second shaft member 2330 applies force from both sides.

Therefore, when the second shaft member 2330 is inserted more deeply into the inside of the center holder 2340, the second elastic member 2360 is contracted while buffering the force into which the second shaft member 2330 is inserted. , this force can be offset by the elastic force.

Meanwhile, the second shaft member 2330 may be inserted into the center holder 2340 , and may be inserted through the second locking jaw portion 2342 to a portion of the second extension portion 2341 . That is, based on the cross-section of the center holder 2340 , the second shaft member 2330 is inserted from both sides of the center holder 2340 , and the second elastic member 2360 is disposed at the center of the second extension part 2341 . is disposed, the second shaft member 2330 is inserted to protrude through the second locking jaw portion 2342 to the second extension portion 2341 so that the second shaft member 2330 is disposed on both sides of the second elastic member 2360 . can be placed.

Therefore, a load is applied to the center holder 2340 by the leg massage unit 2000 to prevent the center holder 2340 from being damaged or the second shaft member 2330 being separated from the center holder 2340. can
