The massage module 1400 moves along the first rail portion (R1) of the seat frame 110, the second rail portion (R2) of the back frame 120, and the rail of the connection block 130, and provides massage to the user. can be provided.

In the massage module 1400 according to the present invention, the connecting unit CN is arranged to connect the seat frame 110 and the back frame 120, so that the movement range of the massage module 1400 can be expanded. That is, the massage module 1400 can massage the user's buttocks when driven on the seat frame 110, and can massage the user's back when driven on the back frame 120. In particular, one massage module 1400 may have a range of motion for both the seat frame 110 and the back frame 120.

The massage module 1400 may include a module body 1410, a massage unit 1420, and a movement unit 1430.

The module body 1410 may form the overall shape of the massage module 1400 by combining each component of the massage module 1400. For example, the massage unit 1420 and the moving unit 1430 may be coupled to the module body 1410.

The massage unit 1420 may provide a massage to the user's body. The massage unit 1420 may be in direct contact with the user's body, but may also be in indirect contact with the user's body through a separate component, such as a cover that covers the outside of the body massage unit.

The massage unit 1420 may include, but is not limited to, a ball massage unit or a roller massage unit.

The movement unit 1430 may move the massage module 1400. The moving unit 1430 can move along the first rail portion (R1), the second rail portion (R2), and the rail (131A). The mobile unit 1430 may be placed on both sides of the module body 1410. In one embodiment, four moving units 1430 may be provided in the module body 1410.

In one embodiment, the moving unit 1430 may include a driving roller 1431 and a support roller 1433.

The driving roller 1431 may move along each tooth of the first rail portion (R1), the second rail portion (R2), and the rail (131A). The driving roller 1431 may receive driving force from a massage module movement actuator (not shown). When the driving roller 1431 rotates, the massage module 1400 can move along the teeth.

The driving roller 1431, the first rail portion (R1), the second rail portion (R2), and the rail 131A may be configured with various mechanisms that transmit driving force. However, hereinafter, for convenience of explanation, the driving roller 1431 is engaged with each tooth of the first rail part R1, the second rail part R2, and the rail 131A, and the teeth are rotated by the rotation of the driving roller 1431. The explanation will focus on the example of a rack and pinion structure that moves along .

In one embodiment, the driving roller 1431 may be a pinion gear having a plurality of teeth on the outer peripheral surface. When the driving roller 1431 rotates, the pinion gear moves along the rack gear, so the massage module 1400 can move along the first rail portion (R1), the second rail portion (R2), and the rail (131A). .

Since the support roller is supported by the first rail part (R1), the second rail part (R2), and the rail (131A), the support roller stably moves the drive roller 1431 when the drive roller 1431 rotates. It may be connected to a portion (R1), the second rail portion (R2), and the rail (131A).

In one embodiment, the support roller 1433 may be disposed adjacent to the drive roller 1431. The support roller 1433 may rotate about the same axis as the drive roller 1431. The support roller 1433 may be disposed at the end of the drive roller 1431.

Since the support roller 1433 moves along the outer edges of the first rail portion (R1), the second rail portion (R2), and the rail (131A), the driving roller 1431 can be stably engaged with the teeth. The support roller 1433 can prevent the driving roller 1431 from being separated from the first rail portion (R1), the second rail portion (R2), and the rail (131A).

As an example, the moving unit 1430 may be driven by receiving power from a separately provided motor or actuator. In this case, the control unit 1210 can provide power to the moving unit 1430 by controlling a motor or actuator, and accordingly, the massage module 1400 can provide a massage to the user's body while moving.

FIGS. 7 and 8 are views showing the connecting unit of FIG. 3, FIGS. 9 and 10 are views showing the connecting block of FIG. 7, and FIG. 11 is a cross-sectional view showing a partial cross section of the connecting block of FIG. 10. .

Referring to FIGS. 7 to 10 , a plurality of connection blocks 130 may be assembled to form a connecting unit CN.

A plurality of connection blocks 130 are assembled to connect the seat frame 110 and the back frame 120, and the arrangement can be adjusted by rotating the back frame 120.

The connection block 130 may include a rail body 131, an extension body 132, and an alignment body 133.

The rail body 131 may be connected to other neighboring connection blocks. The rail body 131 may include a rail 131A, a first connector 131B, a second connector 131C, a connection surface 131D, and a roller groove 131E.

The rail body 131 may have teeth with which the driving roller 1431 of the massage module 1400 engages. The rail 131A has at least one tooth, and a plurality of connection blocks 130 are assembled to form a path along which the driving roller 1431 moves. Hereinafter, for convenience of explanation, the description will focus on an embodiment in which the rail body 131 has three teeth.

The first connector 131B and the second connector 131C of the connection block 130 may be assembled with neighboring connection blocks. The first connector 131B may be connected to a second connector of another neighboring connection block, and the second connector 131C may be connected to a first connector of another neighboring connection block. The first connector 131B and the second connector 131C have a hole into which a connection pin (P) is inserted, and a plurality of connection blocks 130 can be assembled by the connection pin (P).

The connection surface 131D may be disposed on both sides of the first connector 131B to form a space into which the second connector 131C is inserted. The connection surface 131D may have a curvature along the protruding surface of the second connector 131C.

The roller groove 131E may form a path along which the support roller 1433 of the massage module 1400 moves. The roller groove 131E is disposed adjacent to the rail 131A, and the support roller 1433 can be inserted. The roller groove 131E sets the movement path of the support roller 1433, allowing the massage module 1400 to move along the preset path and prevent it from deviating from the path.

The connection block 130 may have a stopper 131P. The stopper 131P may be supported by another neighboring connection block 130 to limit rotation of the connection block 130. The stopper 131P can prevent the assembled connection blocks from sagging down or rotating beyond a preset range.

The stopper 131P may protrude from the first connector 131B toward the second connector 131C. The stopper 131P may protrude into the space between the second connectors 131C. The first connector 131B may have a support groove 131G in which the stopper 131P is supported.

The stopper 131P is inserted into the support groove 131G of another neighboring connection block, and the stopper 131P can move in the support groove 131G within a preset angle range. For example, when the connecting unit CN is unfolded as shown in FIG. 13, the stopper 131P is supported by the support groove 131G to prevent the connection blocks 130 from rotating beyond a preset range.

The extension body 132 may extend upward from the rail body 131. The extension body 132 may connect the rail body 131 and the alignment body 133.

The extended body 132 may have a shape whose thickness or volume decreases toward the top. The portion of the extension body 132 adjacent to the rail body 131 may be formed to have a larger volume than the portion adjacent to the alignment body 133.

The distance between the neighboring alignment bodies may be adjusted as the back frame 120 rotates relative to the seat frame 110. According to changes in the arrangement of the connecting unit CN, the distance between neighboring extension bodies 132 may be adjusted. Since the volume of the extension body 132 decreases upward, the connecting unit CN may be bent as shown in FIG. 12 .

The alignment body 133 may be connected to the extension body 132. The alignment body 133 may be arranged to face the rail body 131. The alignment body 133 may be arranged in parallel with other neighboring connection blocks.

The alignment body 133 may have an alignment protrusion 133A inserted into another adjacent alignment body. The alignment protrusion 133A may be inserted into another neighboring alignment body to align the neighboring connection blocks 130. Referring to FIG. 7, the alignment protrusion 133A of the connection block 130 is inserted to overlap another connection block 130, so that neighboring connection blocks can be connected.

The elastic member 135 may be disposed between neighboring connection blocks 130. The connection block 130 has an alignment groove 134 into which the elastic member 135 is inserted, and the elastic member 135 can be inserted into the alignment groove 134. A protrusion is disposed in the center of the alignment groove 134, so that the position of the elastic member 135 can be set.

The elastic member 135 may be configured as various members that generate elastic force or restoring force. However, for convenience of explanation, the following description will focus on an embodiment in which the elastic member 135 is a spring.

The elastic member 135 is disposed between the connecting blocks 130 and can be compressed or expanded. For example, when the connecting unit CN is bent, the distance between the connecting blocks 130 is reduced and the elastic member 135 is compressed (FIG. 12). When the connecting unit CN is unfolded, the distance between the connecting blocks 130 increases and the elastic member 135 expands (FIG. 13). When the elastic member 135 is expanded, the elastic member 135 supports the neighboring connection block 130, so that the connecting unit CN can maintain a stable expanded arrangement.

The connection block 130 may have teeth of different sizes and shapes. The rail 131A of the connection block 130 is provided with teeth of different shapes, so that the massage module 1400 can stably move the rail 131A even when the connecting unit CN is bent or unfolded.

Referring to FIG. 11, the rail 131A may have a plurality of teeth. The rail 131A may have a first tooth T1 disposed in the center and a second tooth T2 disposed adjacent to the first tooth T1. The second teeth T2 are disposed on both sides of the first teeth T1 and may have a different shape from the first teeth T1.

In one embodiment, the first tooth T1 may be set to be larger in size or volume than the second tooth T2. The cross-sectional area of the first tooth T1 may be set to be larger than the cross-sectional area of the second tooth T2.

In one embodiment, the first tooth T1 may have a first pitch P1, but the second tooth T2 may have a second pitch P2 that is different from the first pitch P1. The second pitch (P2) may be smaller than the first pitch (P1).

In one embodiment, the first tooth T1 may have a blunt thread, but the second tooth T2 may have a sharper thread than the first tooth.

Since the size of the second teeth T2 disposed at both ends of the rail 131A is set to be smaller than the first tooth T1, the massage module 1400 can pass through the bent connecting unit CN.

In detail, the driving roller 1431 of the massage module 1400 moves while passing through the first teeth T1 and the second teeth T2 of the rail 131A. When the connecting unit CN is unfolded as shown in FIG. 13, the pitch D between neighboring rails is wide, so the driving roller 1431 can move along the rails 131A connected to each other.

However, as shown in FIG. 12, when the connecting unit CN is bent, the pitch D between neighboring rails decreases. If the reduced pitch D is smaller than the pitch of the teeth of the driving roller 1431, the driving roller 1431 does not move along the rail 131A.

In the rail 131A of the present invention, the size of the second teeth T2 disposed at both ends of the connection block 130 can be reduced to widen the pitch D between neighboring rails. Since the pitch D is wide, even if the connecting unit CN is bent, the driving roller 1431 can move along the bent connecting unit CN. That is, the rail 131A sets the pitch of the teeth disposed at both ends to be small, so that the massage module 1400 can move along the rail 131A even if the shape or arrangement of the connecting unit CN changes, so that the massage device ( 100) driving range can be expanded.

The support unit 140 is connected to the seat frame 110 and the back frame 120 and can support a plurality of connection blocks 130.

The support unit 140 is installed in an area where the shape of the connecting unit (CN) is changed, so that the massage device 100 can maintain the set arrangement or shape according to the user's settings, and at this time, it prevents the connecting unit (CN) from being damaged. can be prevented.

The support unit 140 may be disposed adjacent to the central axis AX where the seat frame 110 and the back frame 120 are connected. When the back frame 120 is set to have an inclination with respect to the seat frame 110, the support unit 140 may support one side of the connecting unit CN so that the connecting unit CN maintains the set inclination.

One end of the support unit 140 may be rotatably connected to the seat frame 110 and the other end may be rotatably connected to the back frame 120 . Thus, the position of the support unit 140 can be adjusted in response to a change in the position of the seat frame 110 or the back frame 120.

The support unit 140 may include a plurality of support links. A plurality of support links may be arranged along the width direction of the connection block 130. The position or number of support links supported by the plurality of connection blocks 130 may be adjusted according to the rotation of the back frame 120.

One end of the support link may be rotatably connected to the seat frame 110 and the other end may be rotatably connected to the back frame 120 . One end of the support link may be linearly movable to the seat frame 110, or the other end may be linearly movably connected to the back frame 120. One end of the support link may be linearly movable on the first connection frame 111, and the other end may be rotatably installed on the second connection frame 121.

The number of support links is not limited to a specific number and can be set in various ways depending on the size or bending angle of the connecting unit (CN).

The massage device 100 according to an embodiment of the present invention may further include a reinforcing member 145. The reinforcing member 145 is connected to the connecting unit CN, and its shape may change along with the connecting unit CN.

Since the reinforcing member 145 reinforces the connecting unit CN, durability can be maintained even if a high load is placed on the connecting unit CN. The reinforcing member 145 can prevent durability from being deteriorated due to shape deformation of the connecting unit CN.

As an example, the reinforcing member 145 is mounted on the lower surface of the connecting unit CN and may be a leaf spring. The reinforcing member 145 may contact the support roller 1433 of the moving unit 1430 that moves along the lower surface of the connecting unit CN. Additionally, the reinforcing member 145 may contact the guide roller of the support unit 140 that moves along the lower surface of the connecting unit CN.

When the massage device 100 is set in the shape of a chair, the connecting unit CN is bent by the movement of the back frame 120. The reinforcing member 135 may be bent together with the bending connecting unit CN to reinforce the rigidity of the connecting unit CN. In addition, with long-term use of the massage device 100, even if the connecting unit CN is repeatedly bent and restored to its original state, the reinforcing member 145 reinforces the connecting unit CN to improve the durability of the connecting unit CN. does not deteriorate

Referring again to FIG. 3, the massage device 100 may include a driving unit. The driving unit may be an actuator.

The driving unit 150 is mounted on either the seat frame 110 or the back frame 120, and can provide driving force to tilt the seat frame 110 or the back frame 120. For example, if the driving unit 150 is a cylinder device, the seat frame 110 or the back frame 120 can rotate around the central axis AX by adjusting the length of the cylinder.

12 and 13 are diagrams showing the operation of the support unit according to the change in position of the connecting unit.
