Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The sizes and shapes of the components shown in the drawings may be exaggerated for clarity and convenience. In addition, terms defined in consideration of the configuration and operation of the present invention may be changed according to the intention or custom of the user, the operator. Definitions of these terms should be based on the content of this specification.

1 is a front view of a garment (bottom) according to an embodiment of the present invention, Fig. 2 is a side view of a garment (bottom) according to an embodiment of the present invention, A plan view of the joint protection portion.

1 and 2, a functional garment (underneath) according to an embodiment of the present invention includes a garment body 10, a knee formed at a knee joint portion of the garment body 10, And a joint protection portion 20.

The lower body consists largely of the femur, patella, tibial skeleton, quadriceps, hamstring muscles, and calf muscles. The knee, which is the core of the lower body, has a clearance between the femur and the tibia, and is positioned in the tendon of the quadriceps, and smoothes the movement during operation.

Here, the play of the knee joint plays an important role to smooth the movement of the body, whereas if the play is too large, it causes the injury, inversion, and hyperextension. Therefore, in this embodiment, the knee joint protector 20 is formed in the garment to maintain the clearance between the femur and the tibia constantly, and the knee joint is supported to protect the knee joint.

In addition, when the knee joint protection part is formed in a conventional band shape or a band shape, there is a problem in that the band or band covers the whole of the knee gauge and the activity is inconvenient. Therefore, in the present embodiment, the knee protector is formed of a highly stretched film arranged at intervals so that the movement can be smoothly performed in daily life or during exercise, so that the activity can be facilitated.

The knee joint protector 20 is formed of a plurality of highly stretchable films 30 and the stretchable and contractible films 30 are arranged vertically and horizontally at an interval t. Here, the high expansion and contraction film 30 is formed by printing directly on the knee joint portion of the garment main body 10 using a highly elastic material.

Here, the garment main body 10 may be applied with compression wear that presses the muscles as a whole.

The highly stretchable and contractible film 30 is formed by directly printing a silicone with a strong tensile force directly on the garment main body. As the material of the high expansion and contraction film 30, it is possible to use any material as long as it has strong attraction force such as rubber and rubber, and can print on the garment main body.

As described above, since the highly stretchable film 30 is manufactured by directly printing the silicon on the garment main body 10, it is convenient to manufacture the conventional stretchable film 30 as compared with the conventional band or band shape.

The high expansion and contraction film 30 is in the shape of a square and is arranged at an interval t to improve the activity. That is, when the wearer wears clothes, the movement of the knee joint increases. Since the high expansion and contraction film is arranged in an open-net shape, the movement can be smoothly performed while pressing the knee joint sufficiently.

It is preferable that the length h of one side of the high expansion and contraction film 30 is 4 to 10 mm and the interval t between the high expansion and contraction films 30 is 0.5 to 2 mm. Specifically, the length h of one side of the highly stretchable film 30 is 7 mm, and the interval between the highly stretchable films 30 is 1 mm.

Here, the length h and the spacing t of the highly stretchable and contractible film are not fixed but can be variously changed depending on the size and type of the garment.

The high expansion and contraction film 30 may also be formed in various shapes such as a polygonal shape, a circular shape, an elliptical shape, etc. in addition to a square shape.

 The overall shape of the knee joint protector 20 is formed in a U-shape. That is, the knee joint protection portion 20 includes a clearance holding portion 22, 24 for pressing the femur between the femur and the tibia to maintain a clearance between the femur and the tibia constantly, And a suspending portion 26 suspending the knee joint.

Here, the clearance holding portions 22 and 24 are constituted by a first clearance holding portion 22 and a second clearance holding portion 24 for pressing both side surfaces of the knee joint, And is connected to the lower side of the holding portion 22 and the second clearance holding portion 24.

The upper side of the first clearance holding portion 22 and the second clearance holding portion 24 are pressed against the femur and the lower side of the first clearance holding portion 22 and the second clearance holding portion 24 are pressed against the tibia and wrap around ligaments and tendons around the knee, Can be kept constant. In addition, even when the suspension 26 supports the lower side of the knee joint and hangs the knee joint, excessive use of the knee joint can be prevented.

FIG. 4 is a rear view of a garment having a ham spring muscle protecting portion according to an embodiment of the present invention, and FIG. 5 is a plan view of a ham spring muscle protecting portion according to an embodiment of the present invention.

The main thigh muscles involved in the knee motion are quadriceps and ham spring muscles. The hamstring muscles are composed of biceps femoris (50), semitendinosus muscles (54), and semimembranous muscles (56) It connects the buttocks and the knee joints and acts as a main muscle when bending or unfolding the knees.

The ham spring muscle protecting portion 40 according to the present embodiment is designed in accordance with the shape of the hammer spring muscle and the tendon of the ham spring so as to further reduce the burden on the knee joint during operation, The hammer spring muscles can be reduced in tremor and the exercise effect can be improved.

The ham spring muscle protecting portion 40 is formed of a plurality of high stretching films 30 and the high stretching film 30 is formed of a plurality of open netting portions 30 arranged at an interval t as in the knee joint protecting portion 20 described above. (Open-Net) type, and the high expansion and contraction film 30 is formed by directly printing on the knee joint portion of the garment main body by using a highly elastic material.

The ham spring muscle protecting portion 40 has a gradually widening width from the upper end to the lower end and includes an upper portion 42 for pressing the biceps 50, A first branching part 44 which branches from the lower side of the upper side part 42 to the left and encloses the biceps 50 of the thighs and a second branching part 44 which branches from the lower side to the right side in the upper side part 42, And a second branching portion 46 surrounding the second branching portion.

Since the knee joint is a site where skin folding occurs when the knee is folded and stretched, the gap L between the high expansion and contraction films 30 is formed to be wider than the other places, thereby minimizing skin irritation during knee operation.

The length h of one side of the high expansion and contraction film 30 may be 4 to 10 mm and the interval t between the high expansion and contraction films 30 may be 0.5 to 2 mm. The vertical interval L between the lower side extensible film 30 of the first branched portion 42 is 0.5 mm to 1.5 mm because the extruded portion is located below the first branched portion 42, And it is formed to be wider than the gap to minimize skin irritation when the knee is operated.

Specifically, the length h of one side of the high expansion and contraction film 30 is 7 mm, the interval t between the high expansion and contraction films 30 is 1 mm, and the high expansion and contraction film 30 of the low- The gap L may be 0.9 mm.

Next, the test wear with the knee joint protector and the hamstring muscle protector of the present invention was tested for impact absorption and muscle and skin shake.

1. Vertical ground reaction force: The vertical ground reaction force was divided by weight to standardize the difference between vertical and horizontal force.

2. Unit knee maximum angular velocity: The velocity of the knee flexion angle of the analytical section (from the moment when the foot touches the ground to the moment when the knee is flexed to its maximum) is calculated (degree / sec)

3. Analysis of shaking: The shaking in x, y and z directions was confirmed by tracking the positions of the markers attached to thighs and knees in the analysis section (x: left-right shaking, y: before-after shaking, z: - undulation, unit: maximum value - minimum value, △)

Test result

As shown in Table 1, there was no significant difference between the maximum vertical ground reaction forces. The maximum knee angular velocity was higher in Doing 1. And the maximum angular velocity of the knee in the Doing stage 2 was small. The reason for this is that it is not effective for shock absorption which interferes with knee flexion due to more severe compression, and it is excellent in performance to hold muscles in various performance activities due to its small swing.

In the first stage of the Doing experiment, the knee angular velocity was increased during landing to effectively disperse the impact, which was effective in the stability of the knee joint.

In the first and second stages of the experiment, the displacement of the thighs and knees was smaller in all items than in the feet, y, z. Particularly, in the thighs △ z, the difference between the first and the second legs was 5 ㎝ and 4.2 ㎝, respectively. In the knee △ y, Doing 1 step was 2.4 cm and Doing 2 was 2.7 cm smaller.

As described above, it was confirmed that the experimental clothes according to the present embodiment can minimize muscle and skin shaking.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limited to the embodiments set forth herein. Various changes and modifications may be made by those skilled in the art.
