Description

층간소음 완화매트{Interlayer Noise Reduction Mat}Interlayer Noise Reduction Mat

본 고안은 층간소음 완화 매트에 관한 것으로서, 더욱 상세하게는 러닝머신 또는 웨이트 트레이닝기구를 받쳐주는 매트를 6층으로 구성하여 완충성을 높이되 상층부와 하층부에 "V"형 요철을 상하 엇갈리게 반복 형성함으로써, 상층부에 러닝머신이나 트레이닝기구의 눌린 자국이 발생되어 미관상 좋지 않거나 또는 지저분해질 경우 깨끗한 하층부를 위쪽으로 향하게 뒤집어 사용할 수 있으며, 특히 "V"형 요철과 "역V"형 요철이 절반씩 맞물리며 상하좌우 연속 반복되므로 소음이 이들 사이에 갇혀 상쇄되는 다기능의 층간소음 완화 매트에 관한 것이다.The present invention relates to an inter-layer noise-relieving mat, and more specifically, a mat for supporting a treadmill or a weight training device is composed of six layers to increase the buffering property, but repeatedly form a "V" type irregularity in the upper and lower parts, alternately vertically. By doing so, if the treadmill of the treadmill or the training equipment is generated on the upper layer, and it is unsightly or dirty, the clean lower layer can be turned upside down, and in particular, the "V" type irregularity and the "reverse V" type irregularity are halved. It is a multi-functional interlayer noise reduction mat in which noise is trapped between them and canceled out because it is repeated continuously up, down, left and right.

일반적으로 가정에서 사용하는 러닝머신은 천천히 걷기, 조깅 달리기 등 자신의 체력수준에 따라 속도를 임의로 조정할 수 있기 때문에 페이스나 기술향상은 물론, 설정된 목표에 알맞게 가장 안전하고 편안하게 운동할 수 있다. 또한 경사를 마음대로 조절할 수 있어 실내에서 앞산, 뒷산을 오르는 것과 같은 등산 효과도 얻을 수 있으며, 날씨나 환경 등 실외에서 일어날 수 있는 안전사고에 대한 염려가 없고 실제 도로에서보다 신체가 받는 충격이 적다.In general, a treadmill used at home can adjust the speed arbitrarily according to his fitness level, such as walking slowly, jogging, and running, so that he can exercise most safely and comfortably in accordance with his pace and skill improvement as well as set goals. In addition, since the slope can be adjusted at will, climbing effects such as climbing a front mountain or a back mountain indoors are also obtained, and there is no worry about safety accidents that may occur outdoors, such as weather or the environment, and there is less shock to the body than on a real road.

그러나 러닝머신은 이용중에 진동 또는 소음이 밑으로 전달되어 층간소음을 유발시키고, 이웃 간의 갈등을 야기하므로 바닥에 완충재를 깔고 사용해야 되는데 이를 이용하지 않거나 또는 완충재의 성능이 부실할 경우 소음을 완벽하게 차단시킬 수 없는 문제점이 있었다.However, treadmills should be used with a cushioning material on the floor because vibrations or noises are transmitted to the floor during use, causing inter-floor noise and causing conflicts between neighbors. If this is not used or the performance of the cushioning material is poor, noise is completely blocked. There was a problem that could not be done.

종래 등록실용등록 444293호는 받침구가 헬스운동기구를 받침으로써 헬스운동기구 사용 중에 발생하는 진동과 소음 등을 흡수하는 기술이 제시된 바 있다. 종래기술은 내부에 스프링을 구비한 받침구를 운동기구의 본체에 설치한 형태로 운동시 발생하는 진동을 완화하고자 하였으나, 운동시 발생하는 진동이 스프링을 통해 바닥면에 그대로 전달될 수 있으며, 스프링 자체에서 운동에 따른 추가적인 소음이 발생할 수 있는 문제점이 있었다.In the conventional registration utility registration 444293, a technique for absorbing vibration and noise generated during the use of the fitness equipment has been proposed by the support mechanism supporting the fitness equipment. The prior art was intended to mitigate vibrations generated during exercise in a form in which a support with a spring inside is installed on the body of the exercise device, but vibrations generated during exercise can be transmitted to the floor through the spring as it is, spring In itself, there was a problem that additional noise may occur due to exercise.

종래 특허 제1833890호는 상면에 안착되는 운동기구의 하중을 지지하면서도 운동기구 구동 시 하부방향으로 전달되는 진동 및 소음을 감쇠시키는 표층패드; 상기 표층패드 저면에 위치하며, 하부면이 바닥재와 맞닿되, 상부방향으로 함몰 형성된 다수개의 홈이 형성되어 다수개의 홈을 통해 통기되고, 홈과 홈 사이에 돌출되어 바닥재와 맞닿는 다수개의 돌기는 마찰력을 증대시키며 미끄러짐을 방지하는 하층패드; 및 상기 표층패드와 하층패드 사이에 위치하여, 운동기구 구동시 하부방향으로 전달되는 진동 및 소음을 감쇠시키는 완충패드;를 포함하고, 상기 완충패드의 상면 및 하면 중 적어도 어느 하나의 일면에는 단단한 종이재질의 하드패드가 위치하는 러닝머신 전용 충격흡수매트를 제안한 바 있다.Prior art Patent No. 1833890, while supporting the load of the exercise device seated on the upper surface pad while damping the vibration and noise transmitted to the lower direction when driving the exercise device; Located on the bottom surface of the surface pad, the lower surface is in contact with the flooring material, and a plurality of grooves formed in the upper direction are formed to be ventilated through the plurality of grooves, and the plurality of protrusions protruding between the groove and the groove to contact the flooring material have frictional force. A lower layer pad to increase and prevent slipping; And a buffer pad positioned between the surface layer pad and the lower layer pad to attenuate vibration and noise transmitted in a downward direction when the exercise device is driven, and include hard paper on at least one of the upper and lower surfaces of the buffer pad. We have proposed a shock absorbing mat exclusively for treadmills in which a hard pad of material is located.

그러나 종래 매트는 표층패드와 하층패드로 구분되어 있으므로 표층패드가 러닝머신의 바퀴에 눌려 바퀴자국이 깊게 파져 마모될 경우 위아래를 뒤집어 사용할 수 없는 단점이 있었다. 즉 표층패드는 표면이 평탄하게 구성되어 있으므로 마모된 표층패드를 바닥면으로 할 경우 바닥과 밀착되어 공기가 통하지 않으므로 패드의 충격이 바닥에 그대로 전달되어 층간소음을 유발시키고 표층패드 마모시 새것으로 교체 해야되므로 자원낭비가 심한 단점이 있었다.However, since the conventional mat is divided into a surface pad and a bottom pad, there is a disadvantage in that the surface pad cannot be used upside down when the wheel mark is deeply worn out by being pressed against the wheel of a treadmill. In other words, since the surface pad is composed of a flat surface, if the worn surface pad is used as the bottom surface, it is in close contact with the floor and air does not pass, so the impact of the pad is transmitted to the floor, causing interlayer noise, and when the surface pad wears, it is replaced with a new one. There was a drawback of wasting resources.

본 고안은 종래의 문제점을 감안하여 개발한 것으로서, 본 고안의 목적은 러닝머신 또는 웨이트 트레이닝기구를 받쳐주는 매트를 6층으로 구성하여 완충성을 높이되 상층부와 하층부에 "V"형 요철을 상하 엇갈리게 반복 형성함으로써, 상층부에 러닝머신이나 트레이닝기구의 눌린 자국이 발생되어 미관상 않 좋거나 또는 지저분해질 경우 깨끗한 하층부를 위쪽으로 향하게 뒤집어 사용할 수 있으며, 특히 "V"형 요철과 "역V"형 요철이 절반씩 맞물리며 상하좌우 연속 반복되므로 소음이 이들 사이에 갇혀 상쇄되는 다기능의 층간소음 완화 매트를 제공함에 있다.The present design was developed in consideration of the conventional problems, and the purpose of the present design is to increase the cushioning property by constructing a 6-layer mat that supports a treadmill or weight training device, but the "V" type irregularities on the upper and lower parts. By forming them repeatedly, the clean lower layer can be turned upside down when the treadmill of the treadmill or training equipment is generated in the upper layer and is unsightly or dirty. Especially, "V" type irregularities and "reverse V" type irregularities It is to provide a multi-functional interlayer noise-reducing mat in which noise is trapped between them and canceled out because it is repeated in half, and is continuously repeated.

이를 위하여 본 고안은 고무재의 상층부와 고무재의 하층부 사이에 다단의 중간층부가 적층되어 러닝머신이나 웨이트 트레이닝기구를 받쳐주도록 한 층간소음 완화 매트에 있어서, 상기 상층부와 하층부의 표면에는 서로 떨어진 요철이 상하좌우 반복 형성되어서 소음이 이들 요철 사이를 지나면서 상쇄되고, 상기 중간층부는 4개의 층으로 구성되어서 상기 고무재의 완충을 보강하고, 진동을 완화시키며 내구성이 향상되도록 한 특징이 있다.To this end, the present invention is an interlayer noise-reducing mat that is stacked between a multi-layered middle layer portion between an upper layer portion of a rubber material and a lower layer portion of a rubber material to support a treadmill or a weight training device. Repeatedly formed, noise is canceled out as they pass between these irregularities, and the intermediate layer portion is composed of four layers to reinforce the cushioning of the rubber material, dampen vibration, and improve durability.

본 고안에 따르면 상층부와 하층부에 요철이 형성되어 하층부의 기능을 상층부도 수행할 수 있다. 따라서 러닝머신이나 운동기구의 바퀴자국 또는 다리 자국이 상층부에 깊게 형성되어 굳어지기 전에 상하층부를 뒤집어서 하층부로 러닝머신이나 운동기구를 받쳐주기 때문에 상층부에 형성된 자국이 서서히 복원되어 원상태로 평탄해지는 이점이 있다. 또한 상층부와 하층부를 교대로 사용하므로 한쪽만 집중적으로 받쳐줄 때 보다 내구성이 향상되는 이점이 있으며, 요철은 "V"형 요철과 "역V"형 요철이 절반씩 맞물리며 상하좌우 연속 반복되므로 소음이 이들 요철의 사이를 빠져나가는 과정에서 연속적으로 충돌되며 상쇄되므로 소음 저감효과도 뛰어난 등의 이점이 있다.According to the present invention, irregularities are formed in the upper and lower layers so that the upper layer can function as the lower layer. Therefore, since the treads or leg marks of the treadmill or exercise equipment are deeply formed in the upper layer and hardened, the upper and lower layers are turned upside down to support the treadmill or exercise equipment to the lower layer, so the marks formed on the upper layer are gradually restored and flattened to the original state. have. In addition, since the upper and lower parts are used alternately, the durability is improved more when only one side is intensively supported. As for the irregularities, the "V" type irregularities and the "reverse V" type irregularities mesh in half and repeat continuously up, down, left, and right. In the process of passing through the unevenness, there are advantages such as an excellent noise reduction effect since it continuously collides and cancels.

도 1 내지 도 3에서 본 고안 한 실시예의 매트는 상층부(10), 중간층부(30) 및 하층부(20)로 구성되는데, 상층부(10)와 하층부(20)는 같은 재질로 구성되고 각 표면에는 요철(40)이 형성되어 상,하층부(10)(20) 구분없이 뒤집어 사용 가능한 특징을 갖는다. 상기 중간층부(30)는 4개 층으로 구성되는데, 완충과 강도를 보강하고, 진동에 따른 울림을 억제하는 기능을 갖는다.1 to 3, the mat of the embodiment devised in the present invention is composed of an upper layer portion 10, an intermediate layer portion 30, and a lower layer portion 20. The upper layer portion 10 and the lower layer portion 20 are made of the same material, and each surface has The unevenness 40 is formed so that the upper and lower layers 10 and 20 can be turned over without distinction. The intermediate layer portion 30 is composed of four layers, and has a function of reinforcing cushioning and strength and suppressing ringing due to vibration.

각 층별로 재질은 다음과 같다. 상,하층부(10)(20)는 4.0mm 두께의 일반 고무재로써, 경도는 65도 이다. 중간층부(30)는 제1층이 2.5mm 두께의 eva 압축스폰지 재질로 구성되어 고무재의 쿠션을 보강하는 용도이고, 70도의 경도를 갖는다. 제2층은 1.4mm 두께의 고무재로써 경도는 50도이고, 제3층은 진동으로 인한 울림 방지용으로써 2.5mm 두께의 eva 압축스폰지 재질로 구성되며 경도는 40도이고, 제4층은 2mm 두께의 강화 부직포로 구성되고 경도는 70도로 형성된다.Materials for each floor are as follows. The upper and lower layers 10 and 20 are general rubber materials having a thickness of 4.0 mm, and the hardness is 65 degrees. The middle layer portion 30 is used to reinforce the cushion of the rubber material, as the first layer is made of 2.5 mm thick eva compression sponge material, and has a hardness of 70 degrees. The second layer is a 1.4mm thick rubber material with a hardness of 50 degrees, and the third layer is made of an eva compression sponge material of 2.5mm thickness to prevent ringing due to vibration, the hardness is 40 degrees, and the fourth layer is 2mm thickness It is composed of a reinforced non-woven fabric, and has a hardness of 70 degrees.

그리고 상,하층부(10)(20)에는 표면에 요철(40)이 형성되는데, 이들 요철(40)은 "V"형 요철과 "역V"형 요철이 절반씩 맞물리며 상하좌우 연속 반복되는 형태로써, 소음이 이들 요철의 사이를 빠져나가는 과정에서 연속적으로 충돌되며 상쇄되므로 소음 저감효과가 있다. 또한 각 요철(40)은 표면에 미세돌기(41)가 2단으로 돌출되어 하중이 가해지면 압축되면서 요철(40)이 바닥면이나 러닝머신의 바퀴 등에 닿는다.In addition, the upper and lower layer portions 10 and 20 are formed with unevenness 40 on the surface, and these unevenness 40 is a type in which the "V" type unevenness and the "reverse V" type unevenness are halved and continuously repeated. , As the noise continuously collides and cancels in the process of passing between these irregularities, it has a noise reduction effect. In addition, each concavo-convex (40) is a microscopic projection (41) protruding in two stages on the surface is compressed when a load is applied, the concavo-convex (40) touches the bottom surface or the wheel of a treadmill.

이처럼 구성된 본 고안 한 실시예의 매트는 상,하층부(10)(20)가 표면에 요철(40)이 형성되기 때문에 앞뒤 구분없이 사용가능한 이점이 있다. 러닝머신의 바퀴나 웨이트 트레이닝기구의 다리 등이 상층부(10) 또는 하층부(20)에 놓이면 국부적으로 하중이 집중되어 바퀴자국이나 다리자국이 발생되는데, 시간이 지남에 따라 이들 자국이 고착되어 원상태로 회복되지 않고 주저 않게 되며, 또한 꺼진 자국에 의해 상층부(10) 또는 하층부(20)가 파손되는 일이 발생된다.The mat of the presently designed embodiment configured as described above has an advantage that can be used without distinction between front and back because the upper and lower layer portions 10 and 20 have irregularities 40 formed on the surface. When a treadmill wheel or a leg of a weight training device is placed on the upper portion 10 or the lower portion 20, the load is concentrated locally to generate wheel marks or leg marks, and as time passes, these marks become fixed and return to their original state. It does not recover and does not hesitate, and the upper layer portion 10 or the lower layer portion 20 is damaged by the cut-out marks.

종래에는 매트가 앞뒤 구분하여 사용되기 때문에 한쪽 면만 집중하중이 계속 가해져 깊은 자국이 발생되므로 바닥면이 멀정하더라도 새것으로 교체해야 되므로 자원낭비가 심한 문제점이 있었다. 본 고안 한 실시예의 매트는 앞뒤 구분없이 바꿔가며 사용할 수 있으므로 한쪽 면에 자국이 깊게 생기면 뒤집어서 반대쪽 면으로 바퀴나 다리를 받쳐줄 수 있으므로 자국이 생긴 면은 뒤집힌 상태에서 서서히 원상태로 복원되므로 재차 사용할 수 있다.In the related art, since the mat is used separately in front and back, a concentrated mark is continuously applied to one side, and deep marks are generated. Therefore, even if the bottom surface is far away, it has to be replaced with a new one, resulting in severe waste of resources. The mat of the embodiment of the present invention can be used interchangeably back and forth, so if a mark is deep on one side, it can be turned over and supported by a wheel or leg on the other side, so the side with the mark is restored to its original state in an inverted state and can be used again. .

또한 본 고안은 6개의 층으로 구성되어 완충성과 진동억제능력 및 질긴성질이 보완된 것으로서, 중간층부(30)에 마련된 제1층과 제3층은 고무재 쿠션을 보강하고, 진동을 억제한다. 그리고 제2층과 제4층은 매트의 내구성을 높이기 위하여 강도를 보강하는 용도로 사용된다.In addition, the present design is composed of six layers, and the buffer, vibration suppression ability, and toughness are complemented, and the first and third layers provided in the intermediate layer portion 30 reinforce the rubber cushion and suppress vibration. In addition, the second and fourth layers are used for reinforcing the strength to increase the durability of the mat.

따라서 매트에서 발생되는 진동이 억제되고 완충되며, 또한 질긴 성질이 보강되어 내구성이 뛰어나므로 오래 사용할 수 있는 등의 이점이 있다.Therefore, the vibration generated by the mat is suppressed and cushioned, and the toughness is reinforced, so it has excellent durability and has the advantage of being able to be used for a long time.

또한 상,하층부(10)(20)의 요철(40)은 "V"형과 "역V"형이 절반씩 맞물리며 상하좌우 연속 반복되기 때문에 소음이 이들 요철의 사이를 빠져나가는 과정에서 연속적으로 충돌되며 상쇄되므로 소음저감효과를 높일 수 있는 이점이 있다.In addition, the unevenness 40 of the upper and lower layers 10 and 20, the "V" type and the "reverse V" type mesh in half, and continuously repeats up, down, left, and right, so that noise continuously collides in the process of passing between these irregularities. It is offset and has the advantage of increasing the noise reduction effect.
