도 1은 본 발명의 골프연습용 충격완충네트(100) 구조를 도시한 것이다.1 shows the structure of the shock-absorbing net 100 for golf practice of the present invention.
도 1을 참조하면, 상면, 측면 및 후면의 골격을 구성하는 프레임부(200)와 상기 프레임부(200)를 각각 감싸 상면, 측면, 후면을 구성하는 네트부(300) 및 상기 상면을 구성하는 네트부(300)에 설치되는 충격완충스커트(400)를 포함하는 것을 특징으로 하는 골프연습용 충격완충네트(100)에 관한 것이다.1, the frame part 200 constituting the skeleton of the upper surface, the side surface and the rear surface, and the net part 300 constituting the upper surface, the side surface, and the rear surface by wrapping the frame part 200, respectively, and the upper surface constituting the upper surface It relates to a shock-absorbing net 100 for golf practice, characterized in that it includes a shock-absorbing skirt 400 that is installed in the net portion 300 .
상기 프레임부(200)는 도 1과 같이 전방 좌,우측과 후방이 서로 연결되어 육면체로 구성됨이 바람직하지만 필요에 따라서 얼마든지 모양은 변화될 수 있다. 상기 프레임부는(200) 후방을 이루는 프레임(210)과, 전방을 이루는 프레임(220)과, 상부를 연결하는 프레임(230)과, 하부를 연결하는 프레임(240)을 포함하게 된다. 이하에서는, 이를 후방프레임(210), 전방프레임(220) 및 측면상,하부프레임(230,240)이라고 칭한다.As shown in FIG. 1 , the frame part 200 is preferably formed of a hexahedron with the front left, right and rear sides connected to each other, but the shape may be changed as needed. The frame portion 200 includes a frame 210 forming a rear portion, a frame 220 forming a front portion, a frame 230 connecting the upper portion, and a frame 240 connecting the lower portion. Hereinafter, this is referred to as the rear frame 210, the front frame 220 and the side upper and lower frames (230,240).
상기 후방프레임(210)은 일정 간격을 두고 좌,우에 수직으로 세워져 설치되는 한 쌍의 후방좌,우측수직프레임(211,212)과, 상기 후방좌,우측수직프레임(211,212)의 상단부와 하단부에 각각 설치되어 수직프레임을 연결시킬 수 있는 후방상,하측수평프레임(213,214)을 포함하게 된다. 또한, 상기 후방좌,우측수직프레임(211,212)과 후방상,하측수평프레임(213,214)이 서로 연결됨에 따라 사각 형태의 틀을 이룰 수 있게 된다.The rear frame 210 includes a pair of rear left and right vertical frames 211 and 212 that are vertically erected on the left and right at regular intervals, and the upper and lower ends of the rear left and right vertical frames 211 and 212, respectively. The rear upper and lower horizontal frames 213 and 214 that can connect the vertical frames are included. In addition, as the rear left and right vertical frames 211 and 212 and the rear upper and lower horizontal frames 213 and 214 are connected to each other, a rectangular frame can be formed.
상기 전방프레임(220)은 후방프레임의 전방 좌측에 설치되는 전방좌측수직프레임(221)과, 상기 후방프레임의 전방 우측에 설치되는 전방우측수직프레임(222), 전방상측수평프레임(223), 그리고 전방하측수평프레임(224)로 구성된다. 측면상부프레임(230)은 상기 전방좌,우측수직프레임(221,222)의 상단과 후방좌,우측수직프레임(211,212)의 상단을 연결하는 측면상부좌측프레임(231)과 측면상부우측프레임(232)로 구성된다. 또한, 측면하부프레임(240)은 상기 전방좌,우측수직프레임(221,222)의 하단과 후방좌,우측수직프레임(211,212)의 하단을 연결하는 측면하부좌측프레임(241)과 측면하부우측프레임(242)로 구성된다.The front frame 220 includes a front left vertical frame 221 installed on the front left side of the rear frame, a front right vertical frame 222 installed on the front right side of the rear frame, a front upper horizontal frame 223, and It is composed of a front lower horizontal frame (224). The side upper frame 230 is a side upper left frame 231 and a side upper right frame 232 connecting the upper ends of the front left and right vertical frames 221 and 222 and the upper ends of the rear left and right vertical frames 211 and 212. is composed In addition, the side lower frame 240 is a side lower left frame 241 and a side lower right frame 242 connecting the lower ends of the front left and right vertical frames 221 and 222 and the lower ends of the rear left and right vertical frames 211 and 212. ) is composed of
또한, 상기 프레임부(200)는 골프를 연습하기 위한 공간에 따라 길이와 폭 및 높이를 다르게 구비할 수 있고, 각각 연결캡으로 연결되면서 분리 가능하게 된다. 상기의 연결캡은 통상적으로 텐트와 같은 폴대를 연결시키는 것으로, 이미 널리 통용화되어 사용되고 있으므로 이의 구조에 대한 자세한 설명은 생략하기로 한다.In addition, the frame unit 200 may have different lengths, widths, and heights depending on the space for practicing golf, and may be separated while being connected to each other by a connecting cap. The connection cap is to connect a pole such as a tent in general, and since it has already been widely used and used, a detailed description of its structure will be omitted.
이러한 상기 프레임부(200)는 육면체로 예를 들어 설명하지만, 골프연습용 충격완충스커트가 설치되는 골프연습장(100)은 그 형상이 반드시 육면체일 필요는 없으며, 기타 다른 형상이어도 본 발명의 원리가 동일하게 적용될 수 있다.Although the frame part 200 is described as an example of a hexahedron, the golf driving range 100 in which the shock-absorbing skirt for golf practice is installed does not necessarily have a hexahedron shape, and the principle of the present invention is the same even if it has other shapes. can be applied
예를 들어, 도 2는 본 발명의 다른 실시 예의 골프연습용 네트를 도시한 도면이다.For example, Figure 2 is a view showing a golf practice net of another embodiment of the present invention.
도 2와 같은 구조를 가진 프레임은 측면상,하부프레임(230,240)의 좌,우 프레임의 길이를 달리한 실시예로서, 이러한 구조는 전방프레임(220)을 후방프레임(210)과 평행이 아닌 사선을 이루도록 형성함으로써, 골프클럽을 스윙해도 골프클럽이 전방좌측수직프레임(221)에 부딪치지 않게 되어 사용의 편의성 및 스윙의 안전성을 극대화할 수 있다. 이러한 구조적인 장점에 의해서 골프공의 위치를 골프연습용 네트에 최대한 가깝게 놓을 수 설계될 수 있고, 이러한 구조는 또한 타격되는 골프공이 네트 바깥쪽으로 벗어나는 경우를 효율적으로 방지하는 것으로서 연습공간의 크기를 줄일 수 있는 특징이 있다. The frame having a structure as shown in FIG. 2 is an embodiment in which the lengths of the left and right frames of the lower frames 230 and 240 are different on the side, and this structure is a diagonal line that is not parallel to the rear frame 210 and the front frame 220. By forming so as to achieve this, even when the golf club is swinging, the golf club does not collide with the front left vertical frame 221 , thereby maximizing the convenience of use and the safety of the swing. Due to this structural advantage, it can be designed to place the position of the golf ball as close as possible to the golf practice net, and this structure can also reduce the size of the practice space by effectively preventing the hitting golf ball from deviate from the outside of the net. there is a characteristic
이때, 전방상측수평프레임(223)의 우측 꼭지각을 60도, 45도로 변경하며 모든 골프클럽으로 타격 시험한 결과, 모든 타격에 대한 안전성을 100% 확보하며 최소의 필요 설치공간을 사용함과 동시에 최적의 우측 꼭지각 각도는 60도로 판단되고, 45도의 경우 60도 대비 설치공간이 약 40% 이상 더 필요할 수 있다.At this time, the right vertex angle of the front upper horizontal frame 223 was changed to 60 degrees and 45 degrees, and as a result of hitting tests with all golf clubs, 100% safety against all hits was ensured, the minimum required installation space was used, and the optimal The right apex angle is judged to be 60 degrees, and in the case of 45 degrees, more than 40% of the installation space may be required compared to 60 degrees.
다시 도 1을 참조하면, 상기 네트부(300)는 상기 프레임부(200)를 각각 감싸 상면, 측면 및 후면을 구성하도록 설치되어 타격되는 골프공을 막아줄 수 있게 된다. 즉, 상기 후방프레임(210)과 전방프레임(220) 및 측면상,하부프레임(230,240)의 안쪽 면에 네트부(300)가 설치되어 전방을 제외한 후방 및 좌,우측을 막아줄 수 있어 전방에서 골프공을 타격하면 골프공이 골프연습용 네트부(300) 바깥쪽으로 날아가지 않고 네트부(300) 안쪽으로 떨어지게 된다. 이하에서는, 상면을 구성하는 네트를 상면네트, 측면을 구성하는 네트를 측면네트 및 후면을 구성하는 네트를 후면네트라고 칭한다. 또한, 상기 네트부(300)는 프레임부(200)에 와이어로 감거나 벨크로 테이프로 고정시킬 수 있게 된다.Referring back to FIG. 1 , the net part 300 is installed to surround the frame part 200 , respectively, to form an upper surface, a side surface, and a rear surface to prevent a golf ball being hit. That is, the rear frame 210 and the front frame 220, and the side upper and lower frames (230,240) on the inner surface of the net portion 300 is installed to block the rear and left and right sides except for the front from the front When the golf ball is hit, the golf ball falls inside the net portion 300 without flying out of the net portion 300 for golf practice. Hereinafter, the net constituting the upper surface is referred to as an upper surface net, the net constituting the side surface is referred to as a side net, and the net constituting the rear surface is referred to as a rear net. In addition, the net part 300 can be wound around the frame part 200 with a wire or fixed with a Velcro tape.
통상 후방상측수평프레임(213)은 금속제 또는 강한 플라스틱으로 제조된다. 또한 타겟천(310)은 후면네트 바로 전방에 일정 간격을 두고 상부 네트에 고정후크나 밸크로테이프에 의해서 고정되는데, 이렇게 고정되는 타겟천(310)은 자중에 의해서 고정되는 타겟천(310)의 상부쪽은 자중에 의해서 강한 인장력이 작용하게 된다. 따라서 타격된 골프공이 후방상측수평프레임(213)을 충돌할 경우 공은 강한 충격에 의해서 튕겨져 나오게 된다. 타격천의 상부에 반발력이 있는 이유는, 상부에 공이 맞았을 경우, 타격천의 길이(무게) 때문에 아래부분이 위로 들러올려지지 못하여 이 힘을 흡수하지 못하기 때문이다. 또한 타격된 골프공이 상기 상부 네트와 상기 상부네트에 고정된 타겟천(310)의 상단 사이의 공간을 통과하는 경우 역시 통과된 골프공이 후방상측수평프레임(213)을 충돌할 가능성이 커서 이 경우도 공은 강한 충격에 의해서 튕겨져 나오게 된다. 마지막으로 타격된 골프공이 타겟천(310) 상부에 직접적으로 충돌하는 경우 역시 충돌된 골프공은 타겟천(310)의 작용하고 있는 강한 인장력에 의해서 큰 반발력으로 연습자 방향으로 튕겨져 나오게 된다. 이러한 모든 경우에 연습자나 주변인들에게 부상의 위험을 주게 된다. Usually, the rear upper horizontal frame 213 is made of metal or strong plastic. In addition, the target cloth 310 is fixed to the upper net by a fixing hook or velcro tape at a predetermined distance just in front of the rear net, and the target cloth 310 fixed in this way is the target cloth 310 fixed by its own weight. A strong tensile force is applied to the upper part by its own weight. Therefore, when the hit golf ball collides with the rear upper horizontal frame 213, the ball is bounced out by a strong impact. The reason why there is a repulsive force in the upper part of the striking cloth is that when the ball hits the upper part, the lower part cannot be lifted up due to the length (weight) of the striking cloth and this force cannot be absorbed. In addition, when the hit golf ball passes through the space between the upper net and the upper end of the target cloth 310 fixed to the upper net, there is a high possibility that the passed golf ball collides with the rear upper horizontal frame 213, in this case as well The ball is bounced off by a strong impact. When the last hit golf ball directly collides with the upper part of the target fabric 310, the hit golf ball is also bounced out in the direction of the practitioner with a large repulsive force by the strong tensile force acting of the target fabric 310. In all of these cases, there is a risk of injury to the trainee or those around him.
본 발명의 핵심 구성인 충격완충스커트(400)는 연습자가 타격한 골프공이 탄성이 있는 후방상측수평프레임(213)이나 타겟천(310) 상부에 직접적으로 충돌하는 것을 방지하는 구성으로서, 만약 충격완충스커트(400)이 없는 경우 타격 된 골브공이 후방상측프레임(213)이나 타겟천(310) 상부에 직접적으로 충돌하는 경우가 발생되게 되는 데, 이 경우 충돌 후 반발하여 튀어나오는 것을 원천적으로 방지하는 것을 목적으로 설치된다. The shock-absorbing skirt 400, which is a core configuration of the present invention, is a configuration that prevents a golf ball hit by a practicer from directly colliding with the upper rear upper horizontal frame 213 or the target cloth 310 with elasticity. In the absence of the skirt 400, there is a case in which the hit ball directly collides with the upper rear upper frame 213 or the target cloth 310. installed for the purpose
또한, 골프연습용 충격완충네트(100)에는 골프공의 타깃이 되며 골프공의 타격 충격을 완화시킬 수 있도록 하는 타겟천(310)를 상기 후방프레임(210)에 이격설치 할 수 있다. 상기 타겟천(310)은 본 네트에 직접 걸게 되면 샷을 칠 때마다 손상되므로 고리를 형성하여 착탈가능하게 설치하거나, 또는 연결끈 등으로 설치될 수 있다. 상기 타겟천(310)은 상단부만 프레임에 고정되거나 모든 측면에서 프레임에 고정된 경우 고정된 프레임 근처에서는 매우 팽팽하게 인장력이 작용하고 있다. 이러한 인장력 때문에 타격된 공이 프레임 근처의 타겟천(310) 또는 고리부분에 충돌되는 경우 강한 반발력에 의해서 튕겨 나와 골퍼나 주변인들에게 위험을 줄 수 있다. 본 발명의 핵심 구성인 충격완충스커트(400)는 타격된 공이 탄성이 있는 후면네트나 타겟천(310) 상부로 날아가는 것을 방지하고, 반발하여 튀어나오는 것을 방지하는 역할을 하여 이러한 위험을 방지하고자 설치되는 것이다.In addition, in the shock-absorbing net 100 for golf practice, a target cloth 310 that becomes a target of a golf ball and can alleviate the impact of a golf ball can be installed at a distance from the rear frame 210 . If the target cloth 310 is directly hung on the bonnet, it is damaged every time a shot is hit, so it may be installed to be detachably formed by forming a ring, or may be installed with a connecting string or the like. When only the upper end of the target cloth 310 is fixed to the frame or fixed to the frame from all sides, a very tight tensile force is applied near the fixed frame. When the ball hit due to this tensile force collides with the target cloth 310 or the ring part near the frame, it may be bounced off by a strong repulsive force, giving a risk to the golfer or people around. The shock-absorbing skirt 400, which is a core component of the present invention, prevents the hit ball from flying to the upper net or target cloth 310 with elasticity, and serves to prevent the ball from repulsing and popping out to prevent this risk. will become
상기 충격완충스커트(400)는 상기 상면네트에 연결되어 설치되며, 상기 후면네트에 이격설치될 수 있다.The shock-absorbing skirt 400 is connected to the upper net and installed, and may be installed to be spaced apart from the rear net.
도 3은 본 발명의 골프연습용 충격완충네트(100)가 설치된 골프연습장 구조를 도시한 측면도 및 충격완충스커트(400)를 확대한 도면이다.3 is an enlarged view of the side view and the shock-absorbing skirt 400 showing the structure of the golf driving range in which the shock-absorbing net 100 for golf practice of the present invention is installed.
도 3은 도 1에 도시된 골프연습용 충격완충네트(100)과 동일한 구성으로 이루어진다.3 is made of the same configuration as the shock-absorbing net 100 for golf practice shown in FIG.
상기 충격완충스커트(400)는 도 3에 도시된 바와 같이, 상기 상면네트로부터 수직으로 설치되어 있으며, 상기 후면네트로부터 이격설치된다. 이러한 상기 충격완충스커트(400)는 골퍼의 스윙에 의해서 날아간 골프공이 탄성이 있는 후면네트나 타겟천(310) 상부에 충돌하는 것을 방지하기 위하여 후면네트로부터 이격설치하는 것이 바람직하다. As shown in FIG. 3 , the shock-absorbing skirt 400 is installed vertically from the upper surface net, and is spaced apart from the rear net. The shock-absorbing skirt 400 is preferably installed to be spaced apart from the rear net in order to prevent a golf ball blown by the golfer's swing from colliding with the elastic rear net or the upper target cloth 310 .
본 발명의 충격완충스커트(400)는 골프네트와 타격 전 공 위치에 따라 최적화 된 이격거리와 상기 충격완충스커트(400)의 길이가 계산되는 것이 필요하다.For the shock-absorbing skirt 400 of the present invention, it is necessary to calculate the optimized separation distance and the length of the shock-absorbing skirt 400 according to the golf net and the position of the ball before hitting.
본 발명에서는 최적의 스커트 위치와 길이를 도출하기 위하여 스커트 길이와 위치를 변경시키면서 많은 타격 실험을 수행하였다.In the present invention, many blow experiments were performed while changing the length and position of the skirt in order to derive the optimal position and length of the skirt.
상기 충격완충스커트(400)의 위치와 길이에 따라서 타격된 공의 충돌 위치 값은 달라지므로 상기 충격완충스커트(400)의 설치 위치를 변경하며 최적의 조건을 도출하였을 때, 상기 충격완충스커트(400)는 상기 타격천(310)과 20 내지 40cm 이격설치한 결과 값이 가장 우수하다는 것을 알 수 있었다. Since the impact position value of the hit ball varies according to the position and length of the shock-absorbing skirt 400, when the optimal conditions are derived by changing the installation position of the shock-absorbing skirt 400, the shock-absorbing skirt 400 ) was found to have the best value as a result of installing the striking cloth 310 and 20 to 40 cm apart.
따라서 이하에서는 상기 충격완충스커트(400)와 상기 타격천(310) 사이의 이격거리를 20 내지 40cm 로 가변하면서 타입이 다른 네트에 대한 실시예를 통하여 본 발명의 구성 및 그에 따른 효과를 보다 상세히 설명하고자 한다. 그러나, 본 실시 예는 본 발명을 보다 구체적으로 설명하기 위한 것이며, 본 발명의 범위가 이들 실시 예에 한정되는 것은 아니다.Therefore, in the following, the configuration of the present invention and the effect thereof will be described in more detail through embodiments of different types of nets while varying the separation distance between the shock-absorbing skirt 400 and the striking cloth 310 to 20 to 40 cm. want to However, these examples are for describing the present invention in more detail, and the scope of the present invention is not limited to these examples.

[실험예1][Experimental Example 1]
상기 충격완충스커트(400)를 상기 타격천(310)과 20 내지 40cm 가 이격되도록 설치하고, 다양한 클럽을 이용하여 다양한 힘과 방향으로 상기 타겟천(310)을 타격하면서, 상기 충격완충스커트(400)의 길이를 5cm씩 늘리며 200회의 공을 타격한 후 타격된 공이 튕겨나오는 것을 확인하였다. 이때, 타겟천(310)과 후면네트의 거리는 10cm로 하였다.The shock-absorbing skirt 400 is installed to be spaced apart from the striking fabric 310 by 20 to 40 cm, and while striking the target fabric 310 with various forces and directions using various clubs, the shock-absorbing skirt 400 ) was increased by 5 cm, and after hitting the ball 200 times, it was confirmed that the hit ball bounced off. At this time, the distance between the target cloth 310 and the back net was set to 10 cm.
상기 실시예1에 따른 실험 결과에 의하면, 충격완충스커트(400)가 타격천(310)과 40cm 이격되는 것이 가장 안전하며, 상기 충격완충스커트(400)의 길이가 34 내지 45cm 에서 튕겨나오는 공이 없음을 확인할 수 있었다. According to the experimental results according to Example 1, it is safest that the shock-absorbing skirt 400 is spaced apart from the striking cloth 310 by 40 cm, and the length of the shock-absorbing skirt 400 is 34 to 45 cm. was able to confirm
또한, 동일한 실험을 상기 실시예2에 적용하여 실험 결과, 충격완충스커트(400)가 타격천(310)과 30cm 이격되는 것이 가장 안전하며, 상기 충격완충스커트(400)의 길이가 42 내지 55cm 에서 튕겨나오는 공이 없음을 확인할 수 있었다.In addition, as a result of the experiment by applying the same experiment to Example 2, it is safest that the shock-absorbing skirt 400 is spaced apart from the striking cloth 310 by 30 cm, and the length of the shock-absorbing skirt 400 is 42 to 55 cm. It was confirmed that there was no bouncing ball.
이 때 후면네트와 충격완충스커트(400) 사이의 거리를 y라 하고, 도 4와 같이 타격 전 공의 위치와 후면네트 사이의 거리를 D라고 할 때 y는 D 값의 10 내지 25% 에 해당되는 값을 갖는 것이 바람직하다. 또한, 도 4와 같이 충격완충스커트(400)의 길이를 x 라고 하고, 후면네트의 높이를 H라고 하면, x와 y의 관계식은 기하학적으로 하기의 [수학식1]로 나타낼 수 있다. At this time, when the distance between the rear net and the shock-absorbing skirt 400 is y, and the distance between the position of the hitting hole and the rear net is D as shown in FIG. 4, y corresponds to 10 to 25% of the D value. It is desirable to have a value that is In addition, if the length of the shock-absorbing skirt 400 is x and the height of the rear net is H as shown in FIG. 4 , the relation between x and y can be geometrically expressed as [Equation 1] below.

The value represents the minimum length of the shock-absorbing skirt 400 that prevents the hit ball from directly hitting the upper rear upper horizontal frame 213 of the rear net.
이때, 상기 충격완충스커트(400)의 길이 x는

값의 2 내지 30% 더 길게 즉,
Figure PCTKR2021012011-appb-img-000005
범위로 설치하는 것이 바람직하다. 상기 범위는 상기 인장력이 높은 부위인 타겟천(310)의 상부에 타격된 골프공이 충돌하는 것을 미연에 방지하는 충격완충스커트(400)의 범위로서 다양한 실험을 통해서 최적화한 것이다. 다양한 실험 결과 설치 길이 x가 이 범위를 보다 작은 경우 골프공이 충격완충스커트(400)를 충돌하는 경우 충격완충스커트(400)가 공의 충격에 의해서는 스커트 자체가 말리는 현상이 발생되는 것을 확인할 수 있었다. 또한 설치 길이 x가 이 범위를 보다 큰 경우 충격완충스커트(400) 자중에 의해서 충격완충스커트(400) 상단부분에 반발력이 커서 충격완충스커트(400) 상단부분을 충격하는 골프공이 오히려 네트 밖으로 튕겨져 나오는 현상을 발견할 수 있었다.
At this time, the length x of the shock-absorbing skirt 400 is
Figure PCTKR2021012011-appb-img-000004
2 to 30% longer of the value, i.e.
Figure PCTKR2021012011-appb-img-000005
It is desirable to install it within the range. The above range is the range of the shock-absorbing skirt 400 that prevents the golf ball hitting the upper part of the target cloth 310, which is a high tensile force, from colliding in advance, and is optimized through various experiments. As a result of various experiments, when the installation length x is smaller than this range, when the golf ball collides with the shock-absorbing skirt 400, it was confirmed that the shock-absorbing skirt 400 curled up by the impact of the ball. . In addition, when the installation length x is larger than this range, the repulsive force on the upper part of the shock-absorbing skirt 400 is large due to the weight of the shock-absorbing skirt 400, and the golf ball that impacts the upper part of the shock-absorbing skirt 400 is rather bounced out of the net. phenomenon could be found.
또한 이 범위보다 작은 경우 타격된 공이 상부 네트와 상기 상부네트에 고정된 타겟천(310)의 상단 사이의 공간을 통과하거나 인장력이 높은 타겟천(310)의 상부에 직접적으로 충돌하여 반발력에 의해서 전방으로 튕겨나오는 현상을 발견할 수 있었다.In addition, when it is smaller than this range, the hit ball passes through the space between the upper net and the upper end of the target cloth 310 fixed to the upper net or directly collides with the upper part of the target cloth 310 with high tensile force, and is moved forward by the repulsive force. It was found that the phenomenon of bouncing with
또한, 위 실험 결과를 바탕으로 상기 충격완충스커트(400)와 상기 후면을 구성하는 네트부 사이의 이격거리(y)는, 타격 전 공 위치에서 후면을 구성하는 네트부 사이 거리(D)의 10 내지 15% 가 가장 바람직하다는 것을 발견하였다. In addition, based on the above experimental results, the separation distance (y) between the shock-absorbing skirt 400 and the net portion constituting the rear surface is 10 to 15% were found to be most preferred.
한편, 도 3에 도시된 바와 같이 일 실시예로서 충격완충스커트(400)는 상기 상면네트에 천을 덧대어 'ㄱ'자 형태의 박음질(재봉)을 통해 쉽게 분리되지 않도록 고정할 수 있다. 또한 다른 고정방법으로는 고리를 형성하여 착탈가능하게 설치하거나, 또는 연결끈 등으로 설치될 수 있다.On the other hand, as shown in FIG. 3 , the shock-absorbing skirt 400 as an embodiment can be fixed so as not to be easily separated through the 'L' shape stitching (stitching) by adding a cloth to the upper surface net. In addition, as another fixing method, a ring may be formed to be detachably installed, or it may be installed with a connecting string or the like.
