1 to 4, a joint auxiliary apparatus according to an embodiment of the present invention will be described.

FIG. 1 is a perspective view of a joint assist device according to an embodiment of the present invention, FIG. 2 is a perspective view illustrating a length adjuster of a joint assist device according to an embodiment of the present invention, FIG. 4 is a perspective view showing a band portion of a joint assisting apparatus according to an embodiment of the present invention. FIG.

1 to 4, the joint assist device includes a pair of upper supporters 100 that support both sides of the thigh and face each other to correspond to each other, a pair of upper supporters 100 that support both sides of the lower thigh, A tiltable member 400 that forms an arbitrary tilt angle by aligning the upper and lower supporters 100 and 200 with the lower supporter 200 and the moving state of the wearer; 500, 510, 520, 530, and 540 to be fixed to the thighs and the lower legs to protect the knee joints.

The joint supporting device includes a femoral support bar 110 which connects the upper ends of the upper support 100 to each other to support the front of the thigh and a lower leg supporting bar 110 which supports the lower end of the lower support 200, And a bar (not shown).

The femoral support bar 110 is integrally formed with the upper support 100 and forms a curved surface corresponding to the front shape of the thigh.

The lower support bar 200 is integrally formed with the lower support 200 and forms a curved surface corresponding to the front shape of the lower leg.

Although not shown, the joint assist device includes a pair of upper supports 100 and an upper pad fixed to the inside of the femal support bar 110 to closely contact the thighs, a pair of lower supports 200, And a lower pad fixed to the inside of the bar and brought into close contact with the lower leg.

In addition, one or more of the pair of upper supports 100 may be variably adjustable in length. Or at least one of the pair of lower supports 200 may be variably adjustable in length.

If both the pair of upper supports 100 or both of the pair of lower supports 200 are variably adjustable in length, they can be selectively used for the left knee and the right knee.

When any one of the upper support 100 and the lower support 200 corresponding to the upper support 100 is variable and adjustable in length, the burden of the joint due to the variable length can be dispersed to the thigh and the hip. For example, when only the upper support 100 has a variable length of 100, the pressure applied to the thighs becomes large. However, when the upper support 100 and the lower support 200 each have a variable length of 50, the pressure applied to the thigh can be dispersed to the lower part.

Hereinafter, only one upper support 100 of the pair of upper supports 100 is variably adjustable in length. However, it is natural that the various embodiments described above are included in the scope of right.

When the length of one of the pair of upper supports 100 is made long or short, the connection angle between the upper and lower supports 100 and 200 is different. At this time, the pivoting member 400 may be provided to allow an angle deformation of the upper support 100 and the lower support 200 within a certain range. The pivoting member 400 will be described below again.

The upper support 100 may be deformed inward or outward when the deformation angle of the upper support 100 and the lower support 200 exceeds an allowable degree of angular deformation of the tiltable member 400.

For this purpose, the upper support 100 may be made of a material having elasticity. Specifically, the upper support 100 may be provided to be bent toward the inside or outside of the thigh when an external force is applied. In addition, the upper support 100 can be returned to its original shape when an external force is removed.

Hereinafter, a configuration for varying the length of the upper support 100 will be described.

The upper support 100 includes a first support bar 100a rotatably coupled to the tiltable member 400 and a second support bar 100b integrally connected to the fist support bar 110. The upper and lower support bars 100, Lt; / RTI >

Hereinafter, the length adjusting member 300 is fixed to one side of the second supporting bar 100b, and the first supporting bar 100a moves relative to the length adjusting member 300 to be engaged. Alternatively, however, the length adjusting member 300 is fixed to one side of the first supporting bar 100a, and the second supporting bar 100b moves relative to the length adjusting member 300 to engage.

The upper support 100 is received movably in the longitudinal direction inside the length adjusting member 300 on one side. A plurality of length control holes 120 are formed through the upper support 100 at intervals along the longitudinal direction. A longitudinal guide hole 130 is formed at one side of the length control hole 120. For example, three length-adjusting holes 120 may be formed at regular intervals in the longitudinal direction, and the longitudinal guide holes 130 may be formed to be symmetrical to both sides of the length-adjusting hole 120.

In the meantime, although the longitudinal guide holes 130 passing through the upper support 100 are shown in the drawing, longitudinal guide grooves not passing through the upper support 100 may be provided.

The length adjustment member 300 is engaged with the upper member and the lower member via the second support bar 100b. A fixing member such as a rivet passes through the upper member, the second supporting bar 100b and the lower member to fix the length adjusting member 300 to the second supporting bar 100b. The figure shows that three fixing members are combined.

In addition, the length adjusting member 300 has a space for receiving the first supporting bar 100a between the upper member and the lower member, and the first supporting bar 100a can be inserted through the opening formed at one side have.

Further, the upper member of the length-regulating member 300 forms a recessed portion that is recessed in the upward direction at the end portion. The lower member of the length adjusting member 300 includes a fixing protrusion 310 protruding inward of the recessed portion.

The fixing protrusion 310 is elastically supported on the inner surface of the lower member and is accommodated in the length adjusting hole 120 when there is no external pressure and is detached from the length adjusting hole 120 in a one- . When the fixing protrusion 310 is separated from the length adjusting hole 120, the first supporting bar 100a can move up and down. In this state, the user can raise the length of the upper support 100 by raising the first support bar 100a, or the length of the upper support 100 by lowering the first support bar 100a downward.

For example, when the fixing protrusion 310 is accommodated in the lowest length adjusting hole 120 and the first supporting bar 100a is fixed to the length adjusting member 300, The length becomes the shortest. When the fixing protrusion 310 is downwardly elastically deformed by applying pressure to the fixing protrusion 310 or when the length adjusting member 300 is lifted up, The first supporting bar 100a is moved to a position where the second length adjusting hole 120 is located and accommodated in the length adjusting hole 120 so that the first supporting bar 100a is fixed to the length adjusting member 300, The length of the upper support 100 becomes longer by the distance between the holes 120. [

The fixing protrusion 310 may be provided with an elastic force to the outside. That is, an elastic force is provided in a direction to be received in the length adjusting hole 120, so that the fixing protrusion 310 may not be detached from the inside of the length adjusting hole 120 unless there is an external force in the opposite direction. For example, the fixing protrusion 310 may include an elastic piece that is cut at the center of the lower member and is resiliently supported inside the center of the recessed portion of the upper member, a protrusion formed protruding from the end of the elastic piece, . ≪ / RTI >

In addition, the length adjusting member 300 includes the lengthwise guide protrusion 320. The longitudinal guide protrusion 320 may protrude from the inside of the upper member or the lower member and be received inside the longitudinal guide hole 130.

The longitudinal guide holes 130 may be in the form of a slot extending in the vertical direction. The longitudinal guide holes 130 guide the movement of the longitudinal guide protrusions 320 and define the range of movement. For example, in a state in which the fixing protrusion 310 is accommodated in the length-adjusting hole 120 located at the lowest position, the longitudinal guide protrusion 320 is in contact with the lower end of the longitudinal guide hole 130, . The longitudinal guide protrusion 320 is in contact with or positioned adjacent to the upper end of the longitudinal guide hole 130 in a state in which the fixing protrusion 310 is accommodated in the uppermost length adjusting hole 120 . Therefore, the length of the upper support 100 can be adjusted within a predetermined range.

12 is a plan view showing a length adjuster according to a modified embodiment of the present invention.

Referring to FIG. 12, the upper support 100 may have a varying length so that the angle between the first support bar 100a and the second support bar 100b may vary. In other words, the upper support 100 can be moved in a direction bent in one direction in the vertical direction while varying in length.

Specifically, the first support bar 100a-1 according to the modified embodiment may be provided on both sides in an arc shape.

The guide hole 130-1 may be formed in a shape of an arc corresponding thereto. For example, the pair of guide holes 130-1 may be provided in the same direction and curvature. Therefore, the distance between the pair of guide holes 130-1 is constant.

And the length adjusting hole 120-1 may be disposed along a corresponding imaginary arc.

Next, the tiltable member 400 will be described with reference to FIGS. 5 to 7. FIG.

5 is an exploded perspective view showing a tiltable member 400 of an articulation assist device according to an embodiment of the present invention. 6 is a side view of the pivoting member 400 of FIG. 5 as viewed from above, and FIG. 7 is a side view of the pivoting member 400 of FIG. 5 as viewed from the side.

The pivoting member 400 includes a first connection member 410 connected to the upper support 100, a second connection member 420 connected to the lower support 200, and first and second connection members 410, 420 and a lower cover 440 provided under the first and second connection members 410, 420. The lower cover 440 includes a lower cover 440, The upper cover 430 and the lower cover 440 are detachably coupled to each other and can receive the first and second connection members 410 and 420 therein.

Although the first connecting member 410 is separated from the upper supporter 100 and the second connecting member 420 is separated from the lower supporter 200 in the figure, (410, 420) may be formed integrally with the upper support 100 or the lower support 200.

The first and second connecting members 410 and 420 are rotatably coupled to the upper cover 430 and the lower cover 440. For example, the first and second connection members 410 and 420 may be rotatably coupled to the upper cover 430 and the lower cover 440 by a rotation shaft (not shown). At this time, the upper cover 430 and the lower cover 440 and the rotary shaft (not shown) may be integrally or separately provided.

The first linking member 410 and the second linking member 420 may be gear-engaged with each other. Accordingly, the upper support 100 and the lower support 200 may be simultaneously rotated in opposite directions. This is so that when the joints are folded or unfolded, they correspond to folding or unfolding by the same angle with respect to the center of the joint.

6, when the upper cover 430 and the lower cover 440 are coupled to each other, an opening 402 opened at an angle of 180 degrees or more in the circumferential direction, and an upper portion 430 connecting the upper cover 430 and the lower cover 440 And may include a coupling portion 401. The opening 402 provides an area in which the upper support 100 and the lower support 200 can rotate.

For example, the engaging portion 401 may be provided on the rear side of the knee, and the opening portion 402 may be provided so as to be opened by 180 degrees or more including the front side of the joint. This is because the upper support 100 and the lower support 200 need not be rotated at many angles to the rear of the joint.

The tiltable member 400 may be provided to partially allow the upper support 100 and the lower support 200 to be angularly deformed in the up and down direction. The gap between the upper cover 430 and the lower cover 440 may be greater than the thickness of the upper support 100 and the lower support 200. [

The first and second connection members 410 and 420 include rotation center holes 411 and 421 through which the rotation axis (not shown) of the rotation member 400 passes. At this time, the rotation center holes 411 and 421 may be provided in the form of a long hole having a larger inner diameter in one direction.

The rotation center holes 411 and 421 in the form of a long hole may allow the coupling angle of the upper support 100 and the lower support 200 to be changed. For example, supposing that the rotation axis (not shown) is cylindrical, when the rotation center holes 411 and 421 are provided in a circle having an inner diameter corresponding to the outer diameter of the rotation axis (not shown), the upper support 100 and the lower The support table 200 can not be inclined in the longitudinal direction of the rotation shaft (not shown). However, in the case where the length of the one-direction inner diameter of the rotation center holes 411 and 421 is larger than the outer diameter of the rotation shaft (not shown), it is possible to bend in the longitudinal direction of the rotation shaft (not shown). After the upper support 100 and the lower support 200 are tilted, the rotation center holes 411 and 421 are disposed obliquely to the rotation axis (not shown).

The distance between the upper cover 430 and the lower cover 440 and the difference between the thickness of the upper support 100 and the lower support 200 and the difference between the length of the inner diameter of the rotation center holes 411 and 421 and the rotation axis Can be determined by how much the upper support 100 and the lower support 200 are allowed to bend.

Although not shown in the drawings, a protective pad may be attached to the inside of the tiltable member 400. The protection pad can alleviate the inconvenience that may be caused by the contact of the joint and the tiltable member 400.

Hereinafter, a band unit 500 (510, 520, 530, 540) for winding the upper support 100 and the lower support 200 in the horizontal direction and fixing the upper support 100 and the lower support 200 to each other will be described.

3, the band portion 500 includes a first band portion 510 installed on the first support bar 100a of the upper support 100 and a second band portion 510 installed on the second support bar 100b of the upper support 100.

The second band portion 520 may be installed at a position corresponding to the femoral support bar 110. The fourth band portion 540 may be installed at a position corresponding to the lower support bar 210.

The band unit 500 includes a fixing member 501 fixed to the upper support 100 or the lower support 200, rotary members 503 and 504 rotatably coupled to the fixing member 501, And a band member 506 that is adjustable in length and connects the band connecting member 505 on both sides and the band connecting member 505 on both sides.

FIG. 8 is an exploded perspective view showing a fixing member 501 of the band part 500 of the joint assisting apparatus according to the embodiment of the present invention, and FIGS. 9 and 10 are side views showing the combined state of FIG. And FIG. 11 is a plan view showing the rotation pieces 503 and 504 of the band part 500 of the joint auxiliary device according to the embodiment of the present invention.

The fixing member 501 may be riveted to the upper support 100 or the lower support 200. The rivets passing through the fixing member 501 may be provided integrally with the rotating shaft 502. 8 to 10 show the rotation shaft 502 omitted.

The fixing member 501 may include an upper fixing member 501a and a lower fixing member 501b. The upper fixing member 501a and the lower fixing member 501b can be coupled with each other to be rotatable by a predetermined angle in the circumferential direction.

The upper fixing member 501a and the lower fixing member 501b are provided so as to be circular in a state of overlapping in the vertical direction. The upper fixing member 501a may provide a circular half portion, and the lower fixing member 501b may provide the remaining half of the circular portion.

The upper fixing member 501a and the lower fixing member 501b are provided so as to be able to receive the rotating pieces 503 and 504 inwardly in a state of overlapping in the vertical direction. A protruding portion surrounding the rotating shaft 502 is formed on the lower surface of the upper fixing member 501a and a recessed portion surrounding the rotating shaft 502 may be formed on the upper surface of the lower fixing member 501b. The projecting portion of the upper fixing member 501a is accommodated in the concave portion of the lower fixing member 501b so as to prevent the relative movement of the upper fixing member 501a and the lower fixing member 501b in the radial direction. That is, the upper fixing member 501a and the lower fixing member 501b are provided so as to be capable of only rotating relative to each other about the rotary shaft 502 only.

The upper fixing member 501a is closed at one side and the other side is opened. Conversely, the lower fixing member 501b is opened at one side and closed at the other side. And the closed surfaces of the upper fixing member 501a and the lower fixing member 501b may be 180 degrees or less, respectively. Therefore, when the upper fixing member 501a and the lower fixing member 501b are coupled to each other, both surfaces of the closed surface can not contact at the same time, and a gap is formed on either surface. It is possible for the upper fixing member 501a and the lower fixing member 501b to rotate relative to each other by such an interval.

Grooves formed on the closed side surfaces of the upper fixing member 501a and the lower fixing member 501b to avoid interference with the band connecting member 505, respectively. Because the band connecting member 505 extends outwardly from the inside of the fixing member 501. [

The rotating pieces 503 and 504 may be provided so as to be rotatable in the circumferential direction around the rotating shaft 502. [ At this time, the rotating pieces 503 and 504 can rotate at the same time as the holding member 501.

The rotating pieces 503 and 504 may include a first rotating piece 503 rotating together with the upper holding member 501a and a second rotating piece 504 rotating together with the lower holding member 501b. The first rotating piece 503 and the second rotating piece 504 can be coupled to each other to be rotatable by a predetermined angle in a circumferential direction.

The first rotating piece 503 and the second rotating piece 504 are formed to be circular in a state of overlapping in the vertical direction. And the first pivot 503 provides a half of the circular shape, and the second pivot 504 can provide the other half of the circular shape.

The first rotating piece 503 and the second rotating piece 504 are provided so as to be accommodated in the fixing member 501 in a state of overlapping in the vertical direction.

The first rotation piece 503 is provided in a semicircular shape whose one side corresponds to the inner circular space of the fixing member 501 and the other side is projected to be inserted into the second rotation piece 504. On the contrary, the second rotating piece 504 is provided in a semicircular shape whose other side corresponds to the inner circular space of the fixing member 501, and one side of the second rotating piece 504 is projected to be inserted into the first rotating piece 503. The semicircular shapes of the first rotating piece 503 and the second rotating piece 504 may be 180 degrees or less, respectively. Therefore, when the first rotating piece 503 and the second rotating piece 504 are coupled to each other, both semicircular surfaces can not contact at the same time, and a gap is formed on one of the surfaces. It is possible for the first rotating piece 503 and the second rotating piece 504 to rotate relative to each other by such an interval.

The semi-circular shapes of the first rotating piece 503 and the second rotating piece 504 are grooved to receive the band connecting member 505 to fix the band connecting member 505.

The rotating piece includes two rotating pieces 503 and 504 that rotate about the same axis facing each other. The two rotating pieces 503 and 504 are relatively rotatable with a spacing space between any one of the side surfaces. That is, when one of the rotating pieces 503 is fixed, the other rotating piece 504 can be rotated by a predetermined angle. Or the two rotating pieces 503 and 504 may rotate in different directions to contact each other.

The rotary members 503 and 504 may be provided on the fixing member 501 so as to be rotatable only within a predetermined range. Specifically, the rotating pieces 503 and 504 include a center portion through which the rotating shaft 502 passes, and a fixing portion connected to the body portion and fixing the band connecting member 505. The fixed portion of the rotating pieces 503 and 504 may have a fan shape smaller than 180 degrees. Therefore, even when the two rotating pieces 503 and 504 are coupled to each other, both side surfaces of the rotating pieces 503 and 504 can not contact each other. That is, the rotation pieces 503 and 504 are allowed to rotate in a predetermined angular range in a state where they are arranged to face each other.

As described above, the band member 506 has a certain degree of freedom by the rotating piece which is allowed to rotate in a predetermined angle range. When a person moves the joint with the joint supporting device being worn, the muscle is expanded and contracted according to the movement of the joint, so that the force acts on the band member 506.

If the degree of freedom of the band member 506 is insufficient, the user feels uncomfortable, and pain may be accompanied when the band member 506 is worn for a long time. At this time, the band member 506 can be rotated up and down as the band member 506 is stretched and contracted, so that the band member 506 can be positioned at an optimum position according to the user's attitude.
