That is, the main body portion 4602 may be exposed to the outside of the lower assembly 30 by being moved relative to the control cover 462 and the auxiliary cover 464 .

The adjustment cover 462 has a height adjustment unit 4620 opened to a predetermined size on one side. The height adjusting part 4620 is formed as a groove penetrating the adjusting cover 462, and may be disposed parallel to the body coupler 4604 in a horizontal direction to form one opening. The height adjustment unit 4620 may be formed in a plurality spaced apart in one direction. That is, any one of the plurality of height adjusting units 4620 may be disposed parallel to the main body coupler 4604.

The height adjustment lever 466 may include a pivoting part 4660, an upper cover part 4662, a pivoting support part 4664, and a lever connecting part 4666. At least a portion of the height adjustment lever 466 may be disposed inside the lower body 460 . In detail, the upper part of the main body extension part 4600 may be inserted toward the main body part 4602 and disposed.

The upper cover part 4662 may be disposed on an upper end of the lower body 460 and coupled with the intermediate unit 44 . That is, the upper cover part 4662 may close the inside of the lower body 460 by forming an upper end of the main body part 4602 . A shape for coupling of coupling members to be described later may be formed at an upper end of the upper cover portion 4662 .

The pivoting part 4660 may be rotatably coupled to the pivoting support part 4664 and may be gripped and exposed to the outside of the lower body 460 . That is, the pivoting part 4660 is exposed to the outside so that the user can grip and rotate it. At this time, the main body extension part 4600 connects the rotation part 4660 disposed outside the lower body 460 and the rotation support part 4664 disposed inside the lower body 460. A groove may be formed.

The lever connection part 4666 may be elastically connected to the rotation support part 4664 so as to move as the rotation part 4660 rotates. For example, an elastic member may be disposed between the lever connection part 4666 and the rotation support part 4664. In addition, when the pivoting part 4660 is rotated by an external force, the elastic member is compressed and the lever connecting part 4666 is moved. When the external force is removed from the pivoting part 4660, the elastic member is restored to its original state, and the pivoting part 4660 and the lever connecting part 4666 are returned to their original positions.

The lever connection part 4666 may be provided in a bar shape extending long in the vertical direction. The lever connecting portion 4666 extends along the main body portion 4602 and is disposed therein. In particular, the lever connecting portion 4666 may be disposed extending to a portion where the body coupler 4604 is formed.

Referring to FIG. 6 , the auxiliary assembly 40 may further include a height adjusting member 4606 coupled to the lower body 460 . At least a part of the height adjusting member 4606 is inserted into the lower body 460, and may be installed to be elastically movable toward the inside of the lower body 460 by the lever connection part 4666.

In detail, the height adjusting member 4606 includes an inclined portion 4612 disposed in contact with the lever connecting portion 4666 and a protrusion 4610 extending from the inclined portion 4612 to the outside of the lower body 460. can include At this time, the protruding portion 4610 is disposed to protrude outward through the body coupler 4604.

At this time, the inclined portion 4612 may be formed to protrude outward from the lower body 460 as it goes downward. Accordingly, when the lever connecting portion 4666 is moved downward and an external force is applied to the inclined portion 4612 , the protruding portion 4610 may move toward the inside of the lower body 460 . In addition, the height adjusting member 4606 may be coupled to the lower body 460 through a height adjusting elastic member 4608. Accordingly, when the external force is removed, the protruding portion 4610 may return to the outer side of the lower body 460 again.

Each of the plurality of height adjusting parts 4620 described above may be formed as a groove into which the protruding part 4610 can be inserted. Also, the protruding part 4610 may be inserted into any one of the plurality of height adjusting parts 4620 so that the lower body 460 may be fixed to the adjusting cover 462 at a predetermined position. In addition, as the protruding part 4610 is moved inward of the lower body 460 by an external force, the lower body 460 may be movable with respect to the adjusting cover 462 .

The intermediate unit 44 is disposed between the upper unit 42 and the lower unit 46 . Referring to FIGS. 7 and 8 , the intermediate unit 44 may include an intermediate body 440 coupled to an upper end of the upper cover portion 4662 . The middle body 440 may have a flat plate shape having a larger area in a horizontal direction than the upper cover part 4662 .

The intermediate body 440 and the upper cover part 4662 are coupled through two coupling members, which are divided into a fixed coupling member 4404 and a motion coupling member 4406. The fixed coupling member 4404 and the motion coupling member 4406 are vertically coupled to fix the intermediate body 440 to the upper cover 4662 in the vertical direction.

That is, the middle unit 44 may be fixedly coupled to the lower unit 46 in the vertical direction. In this case, the fixed coupling member 4404 and the motion coupling member 4406 may be spaced apart from each other and individually fixedly couple the middle unit 44 and the lower unit 46 in the vertical direction.

The intermediate body 440 may be formed with a fixed coupling portion 4400 to which the fixed coupling member 4404 is coupled and a motion coupling portion 4402 to which the motion coupling member 4406 is disposed. The fixed coupling part 4400 and the motion coupling part 4402 may be understood as grooves formed on the lower surface of the intermediate body 440 .

At this time, the fixed coupling part 4400 may be formed as a groove having a size corresponding to that of the fixed coupling member 4404 . That is, the fixed coupling member 4404 may be fixed to the fixed coupling portion 4400 in a horizontal direction. Meanwhile, the motion coupler 4402 may be formed as a long groove extending in a horizontal direction. That is, the motion coupling member 4406 may be relatively moved in a horizontal direction along the motion coupling portion 4402 .

In particular, the motion coupling part 4402 may be formed as a long groove extending at a first angle around the fixed coupling part 4400 . That is, the intermediate body 440 may be rotated at a first angle around the fixed coupling part 4400 or the fixed coupling member 4404 . In other words, the intermediate unit 44 may be pivotally installed at a first angle with respect to the lower unit 46 around the fixed coupling member 44040 .

The upper unit 42 is disposed above the auxiliary assembly 40 and corresponds to a portion where the user's arm is seated. Referring to FIGS. 9 and 10 , the upper unit 42 may include an upper body 420 and a guide member 424 . The upper body 420 may have a flat plate shape having a larger area in a horizontal direction than the middle body 440 .

A guide rail 4200 accommodating the guide member 424 is formed in the upper body 420 . In detail, the guide rail 4200 may be formed as a long groove formed in a straight line in a horizontal direction. That is, the upper body 420 may be provided as a flat plate having a long groove formed on a central axis.

The guide member 424 may be provided as a rectangular flat plate extending in a straight line corresponding to the guide rail 4200 . Both sides of the guide member 424 are disposed to be in contact with the guide rail 4200 and relatively move in a straight line in a horizontal direction along the guide rail 4200 .

The guide member 424 may be coupled to the intermediate unit 44 . In detail, the intermediate unit 44 may further include an intermediate cover 442 covering an upper end of the intermediate body 440 . The guide member 424 is coupled to the intermediate body 440 or the intermediate cover 442 through one coupling member. This is divided into a guide coupling member 4240.

The guide coupling member 4240 is vertically coupled to fix the guide member 424 to the intermediate body 440 or the intermediate cover 442 in the vertical direction. In addition, the upper unit 42 may further include an upper cover 422 covering an upper end of the upper body 420 . That is, the upper unit 42 may be fixedly coupled to the middle unit 44 in the vertical direction.

At this time, the upper unit 42 and the middle unit 44 are fixed in the vertical direction through one coupling member. Accordingly, the upper unit 42 may be rotatably installed about the guide coupling member 4240 with respect to the intermediate unit 44 . In addition, the rotation angle may be limited by a groove formed on the middle cover 442 or a protrusion formed on the guide member 424 . In summary, the upper unit 42 may be pivotally installed at a second angle with respect to the intermediate unit 44 around the guide coupling member 424 .

Hereinafter, the operation of the 3D motion chair 1 of the present invention will be described based on the configuration described above. At this time, each operation is divided into first to fourth motions for convenience of description, but each operation may be performed simultaneously and independently of each other.

11 and 12 are reference views for explaining the first motion of the 3D motion chair 1 according to an embodiment of the present invention. The first motion relates to motion of the lower unit 46 .

As shown in FIG. 11 , the lower unit 46 may be disposed in a state in which the body portion 4602 is inserted into the lower assembly 30 . And, as shown in FIG. 12 , the pivoting part 4660 may be gripped and rotated, and the main body part 4602 may be moved upward. In addition, the pivoting part 4660 may be gripped and rotated, and the main body part 4602 may be moved downward.

In detail, when the pivoting part 4660 is gripped and rotated, the lever connecting part 4666 is moved downward to apply an external force to the height adjusting member 4606. Accordingly, the height adjusting member 4606 is moved to the inside of the main body portion 4602, and the protruding part 4610 inserted into any one of the height adjusting parts 4620 is separated. Accordingly, the lower body 460 may be separated from the control cover 462 and moved.

In addition, when an external force is removed from the pivoting part 4660, the pivoting part 4660 and the lever connection part 4666 are moved to their original positions. Then, the external force applied to the height adjusting member 4606 is removed, and the protruding part 4610 protrudes outward from the lower body 460 and is inserted into one of the height adjusting parts 4620 . Accordingly, the lower body 460 may be fixed while being connected to the control cover 462 .

As described above, the height adjustment unit 4620 is provided with a plurality of grooves corresponding to the protrusion 4610 spaced apart in the vertical direction. For example, the height adjusting part 4620 may be formed in nine pieces, and accordingly, the protrusion part 4610 may be coupled to one of the nine pieces. Accordingly, the lower body 460 can be moved in 9 steps and can be moved about 80mm at the maximum.

In this way, the lower body 460 can be moved in the vertical direction, and the middle unit 44 and the upper unit 46 connected thereto can be moved. Therefore, the user can move it up and down as needed and fix it to a desired position.

13 is a reference diagram for explaining the second to fourth motions of the 3D motion chair 1 according to an embodiment of the present invention. FIG. 13 shows a basic position for explaining the operations shown in FIGS. 14 to 18 . At this time, the basic position is set for convenience of explanation, and does not mean that it automatically returns to the position when the external force is removed.

14 is a reference diagram for explaining a second motion of the 3D motion chair 1 according to an embodiment of the present invention. The second motion relates to the operation of the upper unit 42 . As shown in FIG. 14 , the upper unit 42 may be disposed in a state of being slid backward in FIG. 13 .

In detail, when an external force is applied to the upper cover 422 and the upper main body 420 backward, the guide member 424 may be relatively moved along the guide rail 4200 . Accordingly, the upper cover 422 and the upper body 420 may be moved and disposed rearward. On the other hand, when an external force is applied to the upper cover 422 and the upper body 420 forward, the upper cover 422 and the upper body 420 are moved forward by the relative movement of the guide member 424. Can be disposed.

For example, the upper cover 422 and the upper body 420 may be moved about 50 mm in the forward and backward directions. This may correspond to a movable range of the guide member 424 along the guide rail 4200 . In this way, the upper cover 422 and the upper body 420 can be moved in the forward and backward directions. Therefore, the user can move it forward and backward as needed and fix it at a desired position.

15 is a reference diagram for explaining a third motion of the 3D motion chair 1 according to an embodiment of the present invention. The third motion relates to the operation of the upper unit 42 . As shown in FIG. 15 , the upper unit 42 may be disposed in a rotated state in FIG. 13 .

In detail, when an external force is applied to the upper cover 422 and the upper main body 420 in a horizontal direction, the guide coupling member 4240 may be pivoted. That is, the guide member 424 coupled by the guide coupling member 4240 is rotated at a predetermined angle, and the upper body 420 in which the guide member 424 is accommodated and the upper cover 422 connected thereto can be rotated.

As described above, the upper unit 42 may be rotated at a second angle. For example, the upper unit 42 can be rotated by about 20 degrees and can be rotated only to one side in the front-back direction. Such a rotation angle and direction may be changed depending on the shape of the guide member 424 or the middle cover 442 .

16 and 17 are reference diagrams for explaining a fourth motion of a 3D motion chair according to an embodiment of the present invention. The fourth motion relates to the operation of the intermediate unit 44. As shown in FIGS. 16 and 17 , the intermediate unit 44 may be disposed in a rotated state in FIG. 13 .

In detail, when an external force is applied to the intermediate body 440 in a horizontal direction, it may be rotated around the fixed coupling member 4404 . That is, the intermediate body 440 coupled by the fixed coupling member 4404 is rotated at a predetermined angle, and the intermediate cover 442 and the upper unit 42 coupled to the intermediate body 440 can be rotated.

As described above, the intermediate unit 44 may be rotated at a first angle. For example, the intermediate unit 44 can be rotated by about 25 degrees and can be rotated to both sides in the front-back direction. Such a rotation angle and direction may be changed depending on the shape of the motion coupler 4402 and the like.

At this time, comparing the third motion and the fourth motion, the third motion corresponds to the rotation of the upper unit 42 and the fourth motion corresponds to the rotation of the middle unit 44 . At this time, since the upper unit 42 is coupled to the upper portion of the intermediate unit 44, it may be understood that the rotation of the upper unit 42 is included in the fourth motion.

In addition, the third motion is an operation in which the upper unit 42 is rotated around the guide coupling member 4240, and the fourth motion is an operation in which the intermediate unit 44 is rotated around the fixed coupling member 4404. At this time, the guide coupling member 4240 and the fixed coupling member 4404 correspond to coupling members coupled in a vertical direction and are spaced apart from each other in a horizontal direction. That is, the rotation centers of the third motion and the fourth motion do not coincide in the horizontal direction.

Also, the third motion may be an operation in which the upper unit 42 is rotated to one side in the front-back direction, and the fourth motion may be an operation in which the middle unit 44 is rotated to both sides in the front-back direction. For example, the third motion may correspond to an operation of turning only to the left. Accordingly, the first angle may be greater than the second angle.

In addition, the fourth motion may be an operation in which the intermediate unit 44 rotates to both sides in different angular ranges. For example, the third motion may be an operation in which the upper unit 42 is rotated to the left by 20 degrees, and the fourth motion is an operation in which the middle unit 44 is rotated to the left by 20 degrees and to the right by 5 degrees. 15 and 16 show a state in which the intermediate unit 44 is rotated in different directions.

Also, as described above, each motion may be independently and concurrently generated. Among them, a case where the third motion and the fourth motion occur simultaneously is illustrated in FIG. 18 . 18 is a reference diagram for explaining the third motion and the fourth motion of the 3D motion chair 1 according to an embodiment of the present invention. In particular, FIG. 18 shows a state in which the middle unit 44 is operated as shown in FIG. 17 and the upper unit 42 is operated as shown in FIG. 15 .

In summary, the auxiliary assembly 40 is 1) movable in each step in the vertical direction (first motion), 2) capable of sliding movement in the forward and backward direction (second motion), 3) Only the part that touches the arm is rotatable (third motion), and 4) can be rotatably operated as a whole (fourth motion). According to this operation, it is possible to effectively support the user's arm and provide comfort.

In the above, although one embodiment of the present invention has been described in detail, the scope of the present invention is not limited thereto, and various modifications and variations are possible within the scope without departing from the technical spirit of the present invention described in the claims. It will be apparent to those skilled in the art.
