본 고안은 실내가 아닌 야외나 산책로에서 하체 근육의 단련과 더불어 산책을 즐길 수 있는 보행 운동기구에 관한 것이다.The present invention relates to a walking exercise machine that can enjoy walking along with the training of the lower body muscles in the outdoors or walkway, not indoors.

하체 근육을 단련하기 위한 운동기구로서는 사이클과 러닝머신이 일반적으로 알려져 있다. 사이클은 원거리를 주행하기에는 적합하나 단거리의 산책로에서는 사용이 제한된다. 또한, 러닝머신은 실내에서 원하는 속도와 거리를 정하여 운동량을 조절할 수 있는 점과 혹한기나 우천시에도 운동할 수 있는 장점이 있는 반면, 실내에서만 가능하므로 폐쇄되어 있고 속도감이 없어 기분전환의 효과는 매우 낮다고 할 수 있다. 산책로를 걷는 것은 도시인들에게 매우 유용한 체력단련 수단이지만 사람에 따라서는 걷기의 지루함 때문에 지속적으로 운동하기에는 아쉬움이 남는다.As exercise equipment for training lower body muscles, cycles and treadmills are generally known. Cycling is suitable for long distances, but its use is limited on short trails. In addition, the treadmill has the advantage of controlling the amount of exercise by setting the desired speed and distance indoors and the ability to exercise even in cold or rainy days. can do. Walking the promenade is a very useful means of fitness for the city, but some people are left to exercise because of the boredom of walking.

본 고안은 속도감 위주의 자전거와 달리 산책로에서 사용할 수 있으며, 걷기보다는 속도가 빨라서 재미를 느낄 수 있고, 실내용 러닝머신과 달리 야외에서 속도감을 느끼면서 산책과 더불어 하체운동을 할 수 있는 새로운 보행 운동기구를 제공하고자 하는 것이다.Unlike the speed-oriented bicycles, the present invention can be used on trails, and it can be fun because it is faster than walking, and unlike walking treadmills, a new walking exercise that allows walking and lower body exercise while feeling speed in the open air To provide a mechanism.

본 고안은 3륜 자전거와 같은 구조이나 사용자가 서서 탑승하며 두 발은 지면에 닿지 않고 답판을 밟음으로써 전진하는 보행운동기구이다. 서있는 상태에서 답판에 체중을 교호로 가하면서 전진하므로 지면이 고르지 않은 경우 쓰러질 위험이 있다. 이러한 점을 고려하여 불규칙한 지면에 적응하여 탑승자가 균형을 유지할 수 있는 구조가 요구되며, 두 사람이 함께 탑승할 수 있는 구조라면 더욱 바람직할 것이다.The present invention is a walking mechanism such as a three-wheeled bicycle or a user standing and the two feet are advancing by stepping on the answer plate without touching the ground. As you move forward with your weight alternating on your answerboard, there is a risk of falling if the ground is uneven. In consideration of this point, a structure that allows the occupant to maintain balance by adapting to irregular ground is required, and it would be more desirable if the structure allows two people to ride together.

또한, 자동차나 엘리베이터로 운반할 경우 최소한의 공간 내에 수용될 수 있는 구조도 고려해야 할 점이다. 이러한 제반의 요건을 충족시키고 탑승자의 안전성과 적정한 속도감을 부여할 수 있는 보행 운동기구를 제공하는 것이 본 고안의 기술적 과제가 될 것이다.In addition, when transporting by car or elevator, it is also necessary to consider a structure that can be accommodated in the minimum space. It would be a technical task of the present invention to provide a walking exercise machine that satisfies all the above requirements and imparts a passenger's safety and a proper sense of speed.

본 고안은 아이들의 놀이기구인 외발 3륜 자전거와 기본적인 구성이 같다. 외발로 타는 3륜 자전거의 경우 한 발은 자전거에 올려놓고 다른 발로 지면을 뒤로 밀면서 전진하는 방식이나 본 고안은 두 발을 모두 올려놓고 답판을 교호로 밟음으로써 크랭크에 의하여 상,하 왕복운동이 회전운동으로 전환되어 바퀴가 구동되는 방식이다. The present invention has the same basic configuration as a unicycle, which is a children's ride. In the case of a three-wheeled bicycle that rides on one foot, one foot is placed on the bicycle and the other foot is pushed back to the ground.However, the present invention puts both feet on and alternately presses the answer plate to rotate the up and down reciprocating motion by the crank. It is converted to motion and the wheels are driven.

본 고안의 구조를 도면에 의거 상세히 설명하면 다음과 같다.Referring to the structure of the subject innovation in detail as follows.

제1도에서 보는 바와 같이, 본 고안은 핸들(4)과 핸들축(3), 베어링관(5), 후크(5), 전륜(8)이 차례로 결합 되어 조향부(A)를 구성한다. 일반 자전거와 같이 브레이크 장치가 설치되지만 여기서는 편의상 도시를 생략한다.As shown in Figure 1, the subject innovation is the handle 4 and the handle shaft (3), bearing tube (5), hook (5), front wheels (8) in order to form a steering portion (A). The brake device is installed like a normal bicycle, but the illustration is omitted here for convenience.

조향부(A) 의 베어링관(5)에는 전반부는 상향 절곡되고 후방의 일부도 상향 절곡된 좌우측 프레임(1)(2)이 교합하며, 좌우측 프레임(1)(2) 사이에는 전방 브라켓(11)(11')과 전방 연결간(13) 그리고 후방 브라켓(12)(12')과 후방 연결간(14)이 답판 레일(15)(15')을 축으로 유동 되게 결합하여 골격부(B)를 구성한다. 특히, 베어링관(5)과 좌우측 프레임(1)(2)은 도 3에서 보는 바와 같이 베어링관(5)에 돌출된 중심브라켓(6)에 좌우측프레임(1)(2)의 전단에 형성된 유동 브라켓(9)(9')이 볼트축(10)에 의하여 유동 되게 교합 된다. 이는 볼트축(10)을 중심으로 좌우측 프레임(1)(2)의 후방이 각각 상하로 자유롭게 움직일 수 있는 구조이다.In the bearing tube 5 of the steering portion A, the left and right frames 1 and 2, in which the first half is upwardly bent and a part of the rear is also upwardly engaged, are interposed, and the front bracket 11 is between the left and right frames 1 and 2. 11 'and the front connection 13 and the rear bracket 12, 12' and the rear connection 14 are coupled to the plate rail (15, 15 ') to flow in the shaft frame (B). ). In particular, the bearing tube 5 and the left and right frames 1 and 2 are flows formed at the front end of the left and right frames 1 and 2 on the center bracket 6 protruding from the bearing tube 5 as shown in FIG. 3. Brackets (9) (9 ') are mated to flow by the bolt shaft (10). This is a structure in which the rear of the left and right frames 1 and 2 can freely move up and down with respect to the bolt shaft 10, respectively.

답판 레일(15)(15')은 전방을 향하여 상향 경사져 있으며 답판 레일(15)(15')에 끼워 설치된 슬라이더(16)(16')와 좌우측 프레임(1)(2)의 후방에 장착된 후륜 브라켓(22)(22')에 축을 둔 크랭크(21)위에 한 쌍의 답판(17)(17')이 고정되어 작동부(C)를 구성한다.The answer plate rails 15 and 15 'are inclined upward and are mounted to the rear of the left and right frames 1 and 2 and the sliders 16 and 16' fitted to the answer rails 15 and 15 '. A pair of answer plates 17 and 17 'are fixed on the crank 21 which is axially mounted on the rear wheel brackets 22 and 22' to constitute the operating part C.

후륜 브라켓(22)(22')에는 크랭크축에 설치된 구동 스프로켓(23)(23')과 후륜 축에 설치된 후륜 스프로켓(24)(24')이 체인(25)로 연결되어 구동부(D)를 구성한다.Drive sprockets 23 and 23 'installed on the crankshaft and rear wheel sprockets 24 and 24' installed on the rear wheel shaft are connected to the rear brackets 22 and 22 'by the chain 25 to connect the drive unit D. Configure.

조향부의 베어링관(5)과 골격부의 전방연결간(13) 사이에는 조절나사(20)에 의하여 간격이 조절되며 삽입관(18)과 삽입봉(19)이 끼워 결합 되어 절첩부(E)를 구성한다.Between the bearing tube 5 of the steering portion and the front connection section 13 of the skeleton portion, the spacing is adjusted by the adjusting screw 20, and the insertion tube 18 and the insertion rod 19 are fitted to each other so that the folded portion E is connected. Configure.

이상과 같이 구성된 본 고안은 한사람 또는 두 사람이 탑승할 수 있다. 두 사람이 탑승할 경우 앞사람은 핸들을 잡고 뒷사람은 앞사람의 허리를 잡는다. 탑승자가 답판(17)(17')을 교호로 밟으면 크랭크(21)의 회전운동에 의하여 구동스프로켓(23)(23'), 체인(25)(25'), 후륜 스프로켓(24)(24')을 거쳐 후륜(26)(26')이 구동된다. 구동 스프로켓과 후륜 스프로켓의 치차비는 통상 4:1이 바람직한데, 치차비가 그 이하가 되면 속도감이 감소하여 지루하며, 그 이상이 되면 힘이 많이 들거나 과속의 위험이 있다.The present invention configured as described above can be boarded by one or two people. When two people board, the front man grabs the steering wheel and the rear man grasps the waist of the front man. When the occupant alternately steps on the plate 17, 17 ', the drive sprockets 23, 23', chain 25, 25 ', and rear wheel sprockets 24, 24' are driven by the rotational movement of the crank 21. The rear wheels 26 and 26 'are driven through the. The gear ratio of the driving sprocket and the rear wheel sprocket is generally preferred to 4: 1. When the gear ratio is less than that, the speed is reduced and boring, and if it is more than that, there is a risk of excessive force or speeding.

본 고안은 탑승자가 서있는 상태에서 보행운동을 하는 구조이므로 좌우측 프레임이 지면의 높낮이에 따라 상하로 높낮이를 변화시키지 못하면 탑승자가 균형을 잃게 된다. 이러한 문제점을 해결하고자 하는 것이 도 3의 결합구조와 전후방 연결간(13)(14)의 기능이다.The present invention is a structure that performs the walking movement while the occupant is standing, if the left and right frames do not change the height up and down according to the height of the ground, the occupant loses balance. To solve this problem is the function of the coupling structure 13 and 14 between the front and rear connections of FIG.

베어링관(5)과 좌우측 프레임(1)(2)이 볼트 축(10)으로 유동 되게 결합 되어 있으므로 사람이 탑승하면 핸들 축(3)이 뒤로 눕혀진다. 이러한 현상을 저지해 주는 것이 삽입관(18)과 삽입봉(19) 그리고 조절나사(20)로 이루어진 절첩부(E)이다. 평소에는 절첩부가 핸들축(3)이 정 위치에 서 있도록 지주 역할을 하지만, 보행운동기구를 자동차나 엘리베이터에 탑재하는 경우도 4와 같이 부피를 최소화할 수 있는 형태로 변형이 가능하다. 도 4의 상태에서 수직으로 세워 전륜이 최상부로 오게 하면 후륜(26)(26')과 좌우측프레임(1)(2)의 후단이 지면에 닿아 안정된 자세로 서 있게 된다.Since the bearing tube 5 and the left and right frames 1 and 2 are coupled to flow in the bolt shaft 10, the handle shaft 3 is laid back when a person rides. To prevent this phenomenon is the folded portion (E) consisting of the insertion tube 18, the insertion rod 19 and the adjustment screw (20). Normally, the folding part serves as a prop so that the handle shaft 3 stands in the correct position, but when the walking exercise device is mounted on a car or an elevator, it is possible to deform the shape to minimize the volume as shown in FIG. When the front wheels are placed vertically in the state of FIG. 4, the rear wheels 26 and 26 ′ and the rear ends of the left and right frames 1 and 2 touch the ground to stand in a stable posture.

본 고안은 산책하는 것과 사이클 또는 러닝머신이 가지는 장점을 지향하고 단점을 지양함으로써 즐거움을 줄 수 있는 속도와 더불어 지면이 고르지 않은 산책로에서도 안정되게 산책하듯 보행운동을 할 수 있는 특징을 갖는다. The present invention aims to have the advantages of walking and cycling or treadmills, and has the characteristics that can walk the walking motion as if walking stably on uneven trails with a speed that can be enjoyed by avoiding disadvantages.
