Abstract

The present invention relates to a shock-absorbing device for a bicycle pedal and, more specifically, is characterized in that upper and lower shock-absorbing means (10, 10') facing each other are installed on upper and lower portions of an ordinary bicycle pedal (2) and are coupled to each other via a fastening member for use. Thus, as well as being simple to install on an ordinary bicycle pedal, the shock-absorbing device can be universally installed and used. In addition, the upper and lower shock-absorbing means (10, 10') each have shock-absorbing members (15) between an upper plate (11) and a lower plate (12) so as to absorb the shock from upper and lower directions and evenly apply the force to the entire pedal when the pedal is pushed. Thus, pedaling may be carried out smoothly and can be done using little power so that there is no strain on legs, ankles, and knees, and accordingly, a risk of injury is reduced and the pedaling can be easily carried out.

Description

자전거 페달 완충장치bicycle pedal shock absorber
본 발명은 자전거 페달 완충장치에 관한 것으로서, 좀더 상세하게는 자전거 페달 상하로 결합 설치하여 페달을 밟을 때 상하 완충 작동하도록 하는 자건거 페달 완충장치에 관한 것이다.The present invention relates to a pedal shock absorber for a bicycle, and more particularly, to a shock absorber for a bicycle pedal, which is installed in combination with a bicycle pedal up and down to act as a shock absorber up and down when pedaling.
일반적으로 자전거는 페달을 발로 밟아주는 힘에 의해 앞뒤 바퀴를 회전시켜 이동하는 이동 수단중에 하나이다.BACKGROUND ART In general, a bicycle is one of means of transportation that moves by rotating front and rear wheels by the force of stepping on pedals.
이러한 자전거는 페달을 직접 발로 밟아 주는 힘에 의해 페달링하기 때문에 페달링에 많은 힘이 요구되고 페달을 전체적으로 정확히 밟아 주지 못하는 경우에 페달링이 원활하지 못하게 되는 문제점이 있었다.Since these bicycles pedal by the force of stepping on the pedals directly, pedaling requires a lot of force, and pedaling is not smooth when the pedals cannot be fully stepped on.
특히 언덕이나 불규칙 노면을 이동할 때, 장거리 주행할 때 다리, 발목, 무릅 등에 큰 무리가 가해져 부상의 위험성이 매우 높은 문제점이 있었다.In particular, when moving on hills or irregular road surfaces, or when driving long distances, a large group is applied to the legs, ankles, knees, etc., resulting in a very high risk of injury.
이러한 문제점을 해결하고자 공개실용신안 제1998-065496호에서 스프링 페달이 개시된 바 있는데, 이는 중심 샤프트 전후로 X자형의 페달 프레임을 설치하고, 상기 X자형의 페달 프레임 외측 사이로 스프링을 삽입 설치하여 페달을 밟을 때 스프링의 완충 작용에 의해 페달링이 좀더 수월하고, 다리, 발목, 무릅에 무리가 덜 가도록 하였다.In order to solve this problem, a spring pedal has been disclosed in Publicated Utility Model Publication No. 1998-065496, in which an X-shaped pedal frame is installed in front and behind the central shaft, and a spring is inserted and installed between the outside of the X-shaped pedal frame to step on the pedal. When pedaling, pedaling is easier due to the buffering action of the spring, and less strain is applied to the legs, ankles, and knees.
그러나 상기한 종래 스프링 페달은 범용의 자전거 패달에 설치 사용할 수 없어 페달 전체를 교체 사용하여야 하는 문제점이 있었다.However, the conventional spring pedal described above has a problem in that the entire pedal must be replaced and used because it cannot be installed and used in a general-purpose bicycle pedal.
뿐만 아니라 X자형의 페달 프레임 외측 사이로 스프링을 삽입 설치하기 때문에 페달을 밟아주는 부분의 스프링만이 압축되면서 완충 작동하기 때문에 페달 전체에 고른 힘을 가하지 못하면서 페달링을 좀더 부드럽게 제공하지 못함은 물론 페달링시 여전히 많은 힘이 요구되어 다리, 발목, 무릅에 힘이 들어가 부상의 위험을 여전히 갖게 되는 문제점이 있었다.In addition, since the spring is inserted and installed between the outside of the X-shaped pedal frame, only the spring in the part where you step on the pedal is compressed and actuated as a buffer, so you cannot apply an even force to the entire pedal and do not provide pedaling more smoothly. There was a problem that a lot of strength was required, and the strength was applied to the legs, ankles, and knees, and there was still a risk of injury.
본 발명은 상기한 종래 기술이 갖는 제반 문제점을 해결하고자 발명된 것으로서, 일반 자전거 페달 상하로 결합하여 간단히 설치 사용함은 물론 범용적으로 설치 사용할 수 있도록 하는데 그 목적이 있다.The present invention was invented to solve the various problems of the prior art, and the purpose of the present invention is to enable universal installation and use as well as simple installation and use by combining the pedals of a general bicycle up and down.
본 발명은 페달을 밟을 때 상하 완충 작동하면서 페달 전체에 고른 힘을 가하도록 하므로 페달링이 부드럽고, 적은 힘으로 페달링이 가능하여 다리, 발목, 무릅에 무리를 가하지 않게 되므로 부상의 위험이 적고 페달링이 수월하게 제공되도록 하는데 그 목적이 있다.According to the present invention, pedaling is smooth and pedaling is possible with a small amount of force, so that the legs, ankles, and knees are not subjected to strain, so the risk of injury is reduced and pedaling is easy. Its purpose is to provide
이러한 본 발명은 자전거 페달의 상,하부에 페달을 밟을 때 상,하 완충 작동하는 상,하 완충 수단을 설치 구성하되, 상기 상,하 완충 수단은 상판과 하판 및 상기 상판과 하판 사이에 적어도 둘 이상 위치로 설치되는 완충 부재로 구성하고, 상기 상부 완충 수단의 하판과 하부 완충 수단의 상판 외측에 체결 구멍을 상하로 관통 형성하여 체결 부재를 삽입 체결하는 것에 의해 상,하부 완충 수단을 고정 설치하도록 구성함에 그 특징이 있다.The present invention is configured by installing upper and lower buffer means for operating the upper and lower buffers when the pedal is stepped on the upper and lower parts of the bicycle pedal, wherein the upper and lower buffer means are at least two between the upper and lower plates and the upper and lower plates. It consists of a buffer member installed in an abnormal position, and the upper and lower buffer means are fixedly installed by forming fastening holes vertically through the lower plate of the upper buffer means and the outer surface of the upper plate of the lower buffer means, and inserting and fastening the fastening member. Its composition has its own characteristics.
본 발명에 따르면, 상기 완충 부재는 외부 스프링 내부에 내부 스프링이 삽입되는 이중 스프링 구조로 형성하되, 상기 외부 스프링 보다 내부 스프링의 탄성력이 크도록 와이어 직경을 더 굵게 형성하여 구성함에 그 특징이 있다.According to the present invention, the shock absorbing member is formed in a double spring structure in which an inner spring is inserted into an outer spring, and the wire diameter is formed to be thicker so that the elastic force of the inner spring is greater than that of the outer spring.
본 발명에 따르면, 상기 상부 완충 수단의 상판과 하부 완충 수단의 하판 외 표면에는 접지력 향상을 위해 미세 돌기들을 돌출 형성하여 구성함에 그 특징이 있다.According to the present invention, it is characterized in that fine protrusions are formed protrudingly on the outer surfaces of the upper plate of the upper buffer means and the lower plate of the lower buffer means to improve gripping force.
본 발명에 따르면, 상기 상,하 완충 수단은 상판과 하판의 일측 좌우에 완충 부재를 설치하고, 타측 좌우에 상하 장공이 형성된 상,하 축 지지부가 서로 맞물리도록 형성하여 상기 상,하 축 지지부의 상하 장공에 안내 축을 수평으로 삽입 설치하는 것에 의해 상하 완충 작동시 상하 안내 작동하도록 구성하되, 상,하 완충 수단은 완충 부재와 안내 축의 설치 위치가 서로 반대로 위치하도록 설치 구성함에 그 특징이 있다.According to the present invention, the upper and lower buffer means are formed such that buffer members are installed on left and right sides of one side of the upper and lower plates, and upper and lower shaft supports formed with upper and lower long holes are engaged with each other on the other side, so that the upper and lower shaft support parts By horizontally inserting and installing guide shafts into the upper and lower long holes, the upper and lower buffers are configured so that the installation positions of the buffer member and the guide shaft are opposite to each other.
이러한 본 발명은 일반 자전거 페달의 상,하부에 상,하 완충 수단을 대향 설치하여 체결 부재에 의해 결합 사용하므로 일반 자전거 페달에 간단히 설치 사용함은 물론 범용적으로 설치 사용할 수 있고, 상기 상,하 완충 수단은 상판과 하판 사이에 완충 부재를 설치하여 페달을 밟을 때 상하 완충 작동하면서 페달 전체에 고른 힘을 가하므로 페달링이 부드럽고, 적은 힘으로 페달링이 가능하여 다리, 발목, 무릅에 무리를 가하지 않게 되므로 부상의 위험이 적고 페달링이 수월하게 제공되는 효과를 갖는 것이다.In the present invention, since the upper and lower shock absorbers are oppositely installed on the upper and lower parts of the normal bicycle pedal and used in combination by a fastening member, it can be installed and used universally as well as simply installed on the normal bicycle pedal, and the upper and lower shock absorbers The means is to install a shock absorbing member between the upper and lower plates so that pedaling is smooth and pedaling is possible with little force because it applies an even force to the entire pedal while pedaling up and down when stepping on the pedal. It has the effect of reducing the risk of injury and providing easy pedaling.
특히, 불규칙 노면을 지날때, 언덕을 오를 때, 장거리 주행할 때에 운전자의 피로감 및 부상의 위험을 적게하면서 더 안정적으로 주행할 수 있게 되는 것이다.In particular, when passing an irregular road surface, climbing a hill, or driving a long distance, the driver can drive more stably while reducing fatigue and risk of injury.

이하, 상기한 본 발명의 바람직한 실시 예를 첨부 도면을 참조하여 구체적으로 살펴보기로 한다.Hereinafter, a preferred embodiment of the present invention described above will be described in detail with reference to the accompanying drawings.
본 발명의 자전거 페달 완충장치는 도 1 내지 도 3에 도시된 바와 같이 자전거 페달(2)의 상,하부에 상,하 완충 작동하는 상,하 완충 수단(10)(10')을 결합 설치하여 페달을 밟을 때 상,하 완충 작동하도록 구성하여 이루어진 것이다.As shown in FIGS. 1 to 3, the bicycle pedal shock absorber of the present invention combines upper and lower shock absorbers 10 and 10' for up and down buffering operation at the upper and lower parts of the bicycle pedal 2, It is made by configuring it to act as an up and down shock absorber when stepping on the pedal.
상기 상,하 완충 수단(10)(10')은 상판(11)과 하판(12) 및 상기 상판과 하판 사이에 적어도 둘 이상 위치로 설치되는 완충 부재(15)로 구성하고, 상기 상부 완충 수단(10)의 하판(12)과 하부 완충 수단(10')의 상판(11) 외측에 체결 구멍(12a)(11a)을 상하로 관통 형성하여 체결 부재(20)를 삽입 체결하는 것에 의해 상,하부 완충 수단(10)(10')을 결합 설치하도록 구성한다.The upper and lower buffer means 10 and 10' consist of an upper plate 11 and a lower plate 12 and buffer members 15 installed in at least two positions between the upper plate and the lower plate, and the upper buffer means By forming fastening holes 12a and 11a vertically through the lower plate 12 of (10) and the outer side of the upper plate 11 of the lower shock absorber 10' to insert and fasten the fastening member 20, The lower shock absorber 10 (10') is configured to be installed in combination.
이때, 상기 상,하 완충 수단(10)(10')의 상판(11)과 하판(12)은 판 형태로 형성하되, 페달(2)의 전후 폭 사이즈 보다 더 크게 돌출되는 사이즈로 형성하여 체결 부재로 체결할 수 있는 공간을 확보하도록 구성한다.At this time, the upper and lower plates 11 and 12 of the upper and lower shock absorbers 10 and 10' are formed in a plate shape, but formed in a size that protrudes larger than the front and rear width of the pedal 2 and fastened. It is configured to secure a space that can be fastened with a member.
상기 체결 부재(20)는 체결 볼트(21)와 너트(22)로 구성한다.The fastening member 20 is composed of a fastening bolt 21 and a nut 22.
또한, 본 발명의 상,하 완충 수단(10)(10')은 도 4 및 도 5에 도시된 바와 같이 상기 상부 완충 수단의 상판(11)과 하부 완충 수단의 하판(11) 외 표면에 접지력 향상을 위해 미세 돌기(13)들을 돌출 형성하여 페달링시 미끄럼을 방지하도록 구성할 수 있는 것이다.In addition, as shown in FIGS. 4 and 5, the upper and lower buffering means 10 (10') of the present invention have a gripping force on the outer surface of the upper plate 11 of the upper buffering means and the lower plate 11 of the lower buffering means. For improvement, the fine protrusions 13 may be protruded to prevent slipping during pedaling.
상기 완충 부재(15)는 상하 완충 작동할 수 있는 다양하게 적용 가능하나 스프링으로 형성함이 바람직하다. 상기 스프링의 상,하단은 상판(11)과 하판(12)에 용접 등에 의해 고정시켜 일체로 결합 구성한다.The buffer member 15 can be applied in a variety of ways that can operate up and down, but it is preferable to form a spring.

By doing so, the upper and lower shock absorbers 10 and 10' are simply coupled and installed to the general bicycle pedal 2.
이와 같이 결합 설치되는 본 발명의 장치는 사용자가 상,하 완충 수단(10)(10') 중에 어느 하나의 완충 수단 상부에 발을 얹은 상태로 페달을 밟아 페달링을 행하게 되는 것이다.In the device of the present invention coupled and installed as described above, the user performs pedaling by stepping on the pedal while placing his/her foot on top of one of the upper and lower buffer means 10 and 10'.
이와 같이 상기 상,하 완충 수단(10)(10')을 발로 밟을 때 상판(11)과 하판(12) 사아의 완충 부재(15)가 상하 완충 작동하면서 상판(11)의 일 부분으로 가해지는 힘에도 완충 부재(15)를 통해 하판(12)의 넓은 부분으로 확대 전달되어 페달 전체를 고르게 가압하게 되므로 페달링을 더 정확히 수행하게 되는 것이다.In this way, when the upper and lower buffering means 10 and 10' are stepped on with a foot, the buffer member 15 between the upper plate 11 and the lower plate 12 acts as a buffer up and down, and is applied as a part of the upper plate 11 Even the force is transmitted to the wide part of the lower plate 12 through the buffer member 15 to evenly press the entire pedal, so pedaling is performed more accurately.
뿐만 아니라 상기 완충 부재(15)의 상하 완충 작동에 의해 페달링이 부드럽고 적은 힘으로 페달링이 가능하여 다리, 발목, 무릅에 무리를 가하지 않게 되므로 부상의 위험이 적고 페달링이 수월하게 제공되는 것이다. 특히 불규칙 노면을 지날때, 언덕을 오를 때, 장거리 주행할 때에 운전자의 피로감 및 부상의 위험을 적게하면서 더 안정적으로 주행할 수 있게 되는 것이다.In addition, pedaling can be performed smoothly and with a small force by the up and down buffering operation of the buffer member 15, so that the legs, ankles, and knees are not subjected to strain, so the risk of injury is reduced and pedaling is provided easily. In particular, it is possible to drive more stably while reducing the driver's fatigue and risk of injury when passing irregular road surfaces, climbing hills, and driving long distances.
그 밖에 본 발명 상부 완충 수단의 상판(11)과 하부 완충 수단의 하판(12) 외 표면에는 도 4 및 도 5에서와 같이 미세 돌기(13)들을 돌출 형성하여 페달링시 접지력 향상으로 미끄럼이 방지되면서 더 안정적으로 페달링을 하게 되는 것이다.In addition, as shown in FIGS. 4 and 5, fine protrusions 13 are protruded from the outer surface of the upper plate 11 of the upper buffer unit and the lower plate 12 of the lower buffer unit of the present invention to prevent slipping by improving gripping force during pedaling. It will make pedaling more stable.
또한, 본 발명 상기 상,하 완충 수단(10)(10')의 완충 부재(15)를 도 6 및 도 7에서와 같이 외부 스프링(15a) 내부에 내부 스프링(15b)이 삽입되는 이중 스프링 구조로 형성하여 단독 스프링 구조에 비해 더 안정적으로 상하 완충 작동하도록 하게 되는 것이다. 특히 상기 외부 스프링(15a) 보다 내부 스프링(15b)의 와이어 직경을 더 굵게하여 탄성력이 더 크게 형성하므로 상하 완충 작동시 내,외부 스프링이 상하 방향이 아닌 측 방향으로 비틀어지는 변형을 방지하여 상하 완충 작동을 더욱 원활히 제공하게 되는 것이다.In addition, the buffer member 15 of the upper and lower buffer means 10 and 10' of the present invention has a double spring structure in which an inner spring 15b is inserted into an outer spring 15a as shown in FIGS. 6 and 7 It is formed with a more stable up and down buffer operation compared to a single spring structure. In particular, since the wire diameter of the inner spring 15b is thicker than that of the outer spring 15a, the elastic force is formed to be larger, so that the inner and outer springs are twisted in the lateral direction rather than the vertical direction during the up and down buffering operation. It will provide a smoother operation.
또한, 본 발명은 도 8 내지 도 10에서와 같이 상,하 완충 수단(10)(10')의 상판(11)과 하판(12) 사이에 스프링만을 설치하는 것이 아니라 일측 좌우에는 완충 부재(15), 타측 좌우에는 상,하 축 지지부(16)(16')의 상하 장공(16a)(16a')으로 안내 축(17)을 축 결합하는 것에 의해 페달링에 의한 완충 부재(15)의 상하 완충 작동시 안내 축(17)이 상,하 축 지지부(16)(16')의 상하 장공(16a)(16a')을 따라 수직으로 이동 안내되면서 상하 완충 작동을 더욱 원활히 제공하게 되는 것이다.In addition, the present invention does not install only springs between the upper and lower plates 11 and 12 of the upper and lower buffer means 10 (10') as shown in FIGS. 8 to 10, but buffer members 15 ), and on the left and right of the other side, the guide shaft 17 is axially coupled to the upper and lower long holes 16a and 16a' of the upper and lower shaft supports 16 and 16', thereby buffering the upper and lower parts of the buffer member 15 by pedaling. During operation, the guide shaft 17 moves vertically along the upper and lower slots 16a and 16a' of the upper and lower shaft supports 16 and 16', thereby providing a more smooth up and down buffer operation.
그리고 상기 상,하 완충 수단의 경우에 페달(2) 상,하 위치에서 완충 부재와 안내 축의 설치 위치가 서로 반대로 위치하도록 설치하여 주므로 페달의 상하 위치를 뒤집어도 상,하 완충 수단의 완충 부재와 안내 축의 설치 위치가 일정하게 위치하므로 일정하게 작동하게 되는 것이다.In addition, in the case of the upper and lower buffer means, since the installation positions of the buffer member and the guide shaft are opposite to each other at the upper and lower positions of the pedal 2, even if the pedal is reversed, the buffer member of the upper and lower buffer means Since the installation position of the guide shaft is constantly located, it operates constantly.
이와 같이 상기 상,하 완충 수단(10)(10')의 상하 완충 작동을 다양한 실시 예에 의해 더욱 원활히 제공하므로 전술한 바와 같이 페달 전체에 고른 힘을 가하여 페달링이 부드럽고, 적은 힘으로 페달링하게 되어 부상 위험이 적으며 페달링이 수월하게 제공되는 본 발명의 효과를 더욱 극대화하게 되는 것이다.In this way, since the up and down buffering operation of the upper and lower buffer means 10 and 10' is provided more smoothly by various embodiments, as described above, even force is applied to the entire pedal, so that pedaling is smooth and pedaling with little force The risk of injury is reduced and the effect of the present invention, which provides easy pedaling, is further maximized.
