FIG. 1 is a perspective view schematically showing a joint device according to an embodiment of the present invention and a human body to which the joint device is to be mounted. FIG. 2 is a schematic view showing a state in which a user using the joint device of FIG. Fig. 3 is a schematic side view showing the joint device of Fig. 1; Fig. 3 shows hatching as a means for clearly expressing the relationship of the respective components, though it is not a sectional view. This is the same in the side conceptual views showing the embodiments to be described later.

The joint apparatus according to the present embodiment includes a first retaining ring 100, a second retaining ring 200, an extension 110, a first flexure 210, and a second flexure 220.

The first retaining ring 100 and the second retaining ring 200 are spaced apart from each other. The first retaining ring 100 and the second retaining ring 200 may be attached to or detached from the upper and lower portions of the joints of the human body or the like as shown in FIG. Although not shown in the drawings, each of the first retaining ring 100 and the second retaining ring 200 may have an opening and a locking device so that the first retaining ring 100 and the second retaining ring 200 can be detachably attached to a human body or the like. For example, each of the first retaining ring 100 and the second retaining ring 200 may be connected by a hinge or the like, with two semicircular rings, and there may be a lock that engages the two semicircular rings on the opposite side of the portion where the hinge is located.

The extension 110 has a bar 112 and a distal end 114. The bar 112 extends from the first retaining ring 100 in the direction of the second retaining ring 200 and the end portion 114 is located at the end of the bar 112 in the direction of the second retaining ring 200. The bar 112 may have a cylindrical shape as shown in FIG. Of course, the shape of the bar 112 is not limited to this, and may be a columnar shape having a circular, elliptical or polygonal cross-section. The distal portion 114 may have a variety of shapes, for example, as shown in FIG. 1, the distal portion 114 may have a shape similar to a disc or a cylinder. In Fig. 1, a disk or a cylinder having a central axis in the y-axis direction is shown. Of course, the shape of the distal end 114 is not limited to this, and may have a spherical shape. Of course, the distal end 114 may have various shapes, such as circular, elliptical, polygonal, or combinations thereof.

In FIG. 3, the bar 112 is directly attached to the first stationary ring 100, but the present invention is not limited thereto. For example, an elastic body such as a spring may be interposed between the bar 112 and the first retaining ring 100. Or the bar 112 itself may be formed of a material having elasticity. Preferably, in this and subsequent embodiments or variations, the extension 110 preferably has a stiffness and resilience in construction and material.

The first flexure 210 extends from the second retaining ring 200 in the direction of the first retaining ring 100. The first flexure 210 supports the extension 110. Specifically, the first flexure 210 supports the distal end 114 of the extension 110. The second flexure 220 also extends from the second retaining ring 200 in the direction of the first retaining ring 100. The second flexure 220 also supports the extension 110. Specifically, the second flexure 220 supports the distal end 114 of the extension 110 with the first flexure 210.

Thus, the first flexure 210 and the second flexure 220 support the distal end 114 on both sides (the + x direction and the -x direction) about the extended portion 110. That is, the second flexure 220 may be located on the opposite side of the first flexure 210 about the extension 112. The first flexure 210 and the second flexure 220 serve not only to support the distal end 114 but also to prevent the distal end 114 from escaping in a direction away from the second retaining ring 200 can do. The thickness t1 of the thickest portion of the distal end 114 may be greater than the minimum distance between the first flexure 210 and the second flexure 220. [

The first flexure 210 may have various shapes and may have a first contact portion 211, a first connection portion 213, and a first extension portion 215, for example, as shown in FIG. 3 . The first contact portion 211 may be in contact with the distal portion 114. The first connection part 213 connects the first contact part 211 and the second stationary ring 200. The first extension part 215 is connected to the first contact part 211 so as to be positioned on the opposite side of the first connection part 213 with respect to the first contact part 211. That is, the first extension 215 can be understood as the end of the first flexure 210 in the direction of the first retaining ring 100. Of course, in some cases, the first flexure 210 may not have the first extension 215. This also applies to the following embodiments and modifications thereof. The first flexure 210 may have a flexible characteristic. This is for the purpose of facilitating the operation of the joint apparatus by the elastic restoring force as described later.

The second flexure 220 may have various shapes and may have a second contact portion 221, a second connection portion 223, and a second extension portion 225, for example, as shown in FIG. The second contact portion 221 can be in contact with the distal end 114. The second connection portion 223 connects the second contact portion 221 and the second stationary ring 200. The second extension part 225 is connected to the second contact part 221 so as to be positioned on the opposite side of the second connection part 223 with the second contact part 221 as a center. That is, the second extension 225 can be understood as the end of the second flexure 220 in the direction of the first retaining ring 100. Of course, the second flexure 220 may not have the second extension 225 in some cases. The second flexure 220 may have a flexible characteristic. This is for the purpose of facilitating the operation of the joint apparatus by the elastic restoring force as described later.

The first flexure 210 is a flexible plate-like structure, and at least one of the first flexure 210, the first coupling portion 213, 1 extension 215. [0040] This also applies to the following embodiments and modifications thereof, and the same applies to the case of the second flexure 220 as well.

1 and 2, the extension portions 110 are located on both sides (+ y direction and -y direction) so as to correspond to each other with reference to the center of the first stationary ring 100, The second flexure 210 and the second flexure 220 may be positioned on both sides (+ y direction and -y direction) so as to correspond to each other with respect to the center of the first stationary ring 100. That is, the sets of the extension 110, the first flexure 210, and the second flexure 220 are disposed on both sides (+ y direction and -y direction) so as to correspond to each other with respect to the center of the first stationary ring 100 As shown in Fig. In such a case, the joint device as shown in Fig. 1 moves more easily in a predetermined one direction. For example, in the case of the articulating apparatus as shown in Fig. 1, when the position of the first retaining ring 100 is fixed and the z-axis passes through the center of the first retaining ring 100, The center of the retaining ring 200 can move along the trajectory of approximately a simple movement within the zx plane. As described above, in the case of the joint apparatus according to the present embodiment, it is possible to implement a function of moving more easily in a predetermined direction such as a knee joint or a finger joint of a human body, and restricting movement in other directions.

1 to 3, the first fixing ring 100 and the second fixing ring 200 have a uniform thickness, but the present invention is not limited thereto. For example, the first fixing ring 100 may have a thin thin portion, and the extending portion 110 may be positioned on the thin portion. Such a thin portion is thinner than the other portions of the first stationary ring 100, and thus can have a relatively flexible characteristic. Accordingly, when there is a load or an impact from the outside, which is applied when using the joint device, it can be effectively absorbed through the thin portion. This also applies to the following embodiments and modifications thereof.

Such a joint device may be formed of metal and / or synthetic resin, but the present invention is not limited thereto. That is, the articulating apparatus can be equipped with all kinds of materials having rigidity, elasticity, or flexibility, independently or in combination, so that individual components can be adjusted in stiffness, elasticity or flexibility as needed. This also applies to the following embodiments and modifications thereof.

1 and 2, the first retaining ring 100 is positioned above (+ z direction) and the second retaining ring 200 is positioned below (-z) direction in use of the articulating apparatus, The present invention is not limited thereto. For example, a joint device may be used in which the second retaining ring 200 is positioned above (+ z direction) and the first retaining ring 100 is positioned below (-z). This is because, for example, as shown in FIGS. 1 and 2, when the first stationary ring 100 is positioned above (+ z direction) and the second stationary ring 200 is positioned below (-z direction) Is located in the second stationary ring 200 and extends in the direction toward the first stationary ring 100 and the distal end 114 is located at the end of the bar 112 in the direction of the first stationary ring 100, The flexure 210 and the second flexure 220 are located in the first retaining ring 100 and extend in the direction of the second retaining ring 200. The first flexure 210 and the second flexure 220, 220 may support the distal end 114.

It is preferable that the joint apparatus of the present invention has all components having rigidity and elasticity. It is preferable that the first flexure 210 and the second flexure 220 are more resilient than the other portions.

1 to 3, an example in which the joint apparatus of the present invention is worn by a user will be described. FIG. 1 illustrates a state in which the user stands upright by wearing the joint apparatus of the present invention. At this time, the distal end 114 of the extension 110 is gripped by the first and second pliers 210 and 220. Of course, the first plector 210 or the second plector 220 may be slightly bent, as shown in FIG. 3, etc., in order to elastically grip the distal end portion 114.

2, the second retaining ring 200 moves in the + x and + z directions and the first retainer 210 and the second retainer (not shown) 220 are deformed such as moving or bending. The point where the second contact portion 221 of the second plector 220 meets the second extension portion 225 contacts the bar 112 and the shape of the second plector 220 is deformed, . In this state, the second retainer 220 exerts an elastic restoring force to move the second retaining ring 200 to its original position, and the elastic restoring force is such that the user, who has to maintain the upright position of the knee, It can help you to re-open easily. In addition, when the knee is bent by an unintended external force, the bent knee can be restored to the upright state as shown in FIG. 1, as shown in FIG.

1 to 3, the distal end portion 114 has a first portion having a first width t1 which is the widest width and a second portion having a first width t1 which is located in the direction of the first holding ring 100 about the first portion A second portion having a second width t2 and a third portion positioned in the direction of the second retaining ring 200 about the first portion and having a third width t3. The first contact portion 211 may cover the third portion of the distal end portion 114 through the first portion and the second portion. Of course, the second contact portion 221 may also be wrapped from the third portion of the distal portion 114 through the first portion to the second portion. Thereby preventing the distal end 114 from escaping between the first flexure 210 and the second flexure 220 in a direction away from the second retaining ring 200. [ It is of course also possible to prevent the distal end portion 114 from escaping between the first contact portion 211 and the second contact portion 221 in a direction approaching the second stationary ring 200 .

3, the first contact portion 211 and the second contact portion 221 are in contact with the distal end portion 114 over the entire area, but the present invention is not limited thereto. For example, as shown in FIG. 4, which is a side view schematically showing a joint device according to another embodiment of the present invention, the first contact portion 211 satisfies contact with the distal end portion 114 at least at one point, The second contact portion 221 may also be in contact with the distal end 114 at least at one point.

For example, the first contact portion 211 and the second contact portion 221 may contact the distal end 114 at two points, respectively. More specifically, a first point 211a where the first contact portion 211 and the first extension portion 213 meet and a second point 211b where the first contact portion 211 and the first extension portion 215 meet, The first contact portion 211 may contact the distal portion 114 at these two points. That is, the portion between the first point 211a and the second point 211b of the first contact portion 211 may not be in contact with the distal end portion 114. The second contact portion 221 also has a third point 221a where the second contact portion 221 and the second extension portion 223 meet and a second point 221a where the second contact portion 221 and the second extension portion 225 meet A fourth point 221b, at which the second contact portion 221 can contact the distal end 114. That is, the portion between the third point 221a and the fourth point 221b of the second contact portion 221 may not be in contact with the distal end portion 114.

Of course, the contact method with the first contact portion 211 and the terminal portion 114 of the second contact portion 221 may not always be fixed. For example, as shown in FIG. 1, in a state where the user is standing upright by wearing the joint device of the present invention, the first contact portion 211 and the second contact portion 221 are formed in the entire region And may be in contact with the distal end 114.

2, the second retaining ring 200 moves in the + x and + z directions and the second retainer 220 moves or moves in the + x and + z directions Warping, and the like. Specifically, as shown in FIG. 5, the first contact portion 211 still contacts the distal end portion 114 in the entire region, and the second contact portion 221 is deformed to contact the second contact portion 221 and the second A third point 221a at which the extension portion 223 meets and a fourth point 221b at which the second contact portion 221 and the second extension portion 225 meet, May be in contact with the distal end 114 in a pressurized condition. That is, the portion between the third point 221a and the fourth point 221b of the second contact portion 221 may not be in contact with the distal end portion 114.

2, when the user moves the second fixing ring 200 in the + x and + z directions, the second contact portion 221 and the second extending portion 225 The movement of the fourth point 221b is physically restricted as the fourth point 221b where the fourth point 221b contacts the bar 112 near the boundary between the bar 112 and the distal end 114. [ In this state, the deformed second plector 220 exerts an elastic restoring force for moving the second retaining ring 200 to its original position, and the elastic restoring force is such that the knee portion is maintained in an upright state The user can help prevent the knee from bending. In addition, when the knee is bent by an unintended external force, the user can help restore the bent knee to an upright state as shown in FIGS. 1 and 3, as shown in FIGS. 2 and 5 You can give.

FIG. 6 is a schematic side view showing a joint apparatus according to another embodiment of the present invention. FIG. As shown in FIG. 6, in the joint apparatus according to the present embodiment, the distal end portion 114 has a groove 114a at the end of the second fixed ring 200. The first point 211a where the first contact portion 211 and the first connection portion 213 meet is positioned to correspond to the groove 114a of the distal end portion 114 and the second contact portion 221 and the second connection portion 223 are also positioned to correspond to the grooves 114a of the distal end portion 114. As shown in Fig. Of course, the first point 211a and the third point 221a are separated from each other without contacting each other. At this time, the second point 211b where the first contact portion 211 and the first extension portion 215 meet may be in contact with the distal end portion 114, and the second contact portion 221 and the second extension portion 225 may be in contact with the distal end 114 of the second end 221b.

In such a state, for example, when an excessive external force in the -z direction acts on the first retaining ring 100 of the articulating apparatus, the first retaining ring 100 may move in the direction of the second retaining ring 200. [ It is necessary to prevent the end portion 114 from escaping between the first contact portion 211 and the second contact portion 221 in the direction in which the distal end portion 114 approaches the second retaining ring 200. [

The distal end portion 114 of the joint apparatus according to the present embodiment has the groove 114a at the end of the second fixed ring 200 and the first point 211a of the first contact portion 211, And the third point 221a of the second contact portion 221 correspond to the groove 114a of the distal end portion 114. [ Therefore, when an excessive external force acts on the first stationary ring 100 to move the first stationary ring 100 in the direction of the second stationary ring 200 in such a state, a use example using the joint apparatus of FIG. 7 in which the distal end portion 114 is pressed by the first flexure 210 and the second flexure 220 by the force pressing the first flexure 210 and the second flexure 220, The flexure 220 is deformed so that the first point 211a and the third point 221a are brought into contact with each other. Of course, in this process, the second point 211b where the first contact portion 211 and the first extension portion 215 meet may be spaced apart from the distal end portion 114, and the second contact portion 221 and the The fourth point 221b where the second extension part 225 meets may also be spaced apart from the distal end part 114. [

When the first stationary ring 100 moves in the direction of the second stationary ring 200 due to the excessive external force acting on the articulating apparatus, the first point 211a and the third point 221a are brought into contact with each other. It is possible to effectively prevent the distal end portion 114 from escaping between the first contact portion 211 and the second contact portion 221 in the direction of the second retaining ring 200. When the external force disappears, the first flexible member 210 and the second flexible member 220 can be returned to the shape shown in FIG. 6 by the flexible characteristics.

FIG. 8 is a schematic side view showing a joint apparatus according to another embodiment of the present invention. In the case of the joint apparatus according to the present embodiment, a stopper 112a is further provided. The stopper 112a protrudes from the bar 112. The stopper 112a and the bar 112 may be integrally formed or a stopper 112a which is a separate component may be attached on the bar 112 have. The portion of the stopper 112a in the direction of the second retaining ring 200 is in contact with the first extension 215 of the first retainer 210 so that the first retaining ring 100 of the second retaining ring 200 ) Direction in the direction of the arrow. A portion of the stopper 112a in the direction of the second retaining ring 200 can also contact the second extension 225 of the second plier 220. [

The first retaining ring 100 may be moved toward the second retaining ring 200 when an excessive external force acts on the joint device. It is necessary to prevent the end portion 114 from escaping between the first contact portion 211 and the second contact portion 221 in the direction in which the distal end portion 114 approaches the second retaining ring 200. [ When an excessive external force acts on the articulating apparatus, a portion of the stopper 112a in the direction of the second retaining ring 200 is connected to the first extension 215 of the first pliotor 210, And contacts the second extension 225 of the second plector 220.
