Description

충격이 흡수되는 목발{CRUTCH CAPABLE OF ABSORBING A SHOCK}CRUTCH CAPABLE OF ABSORBING A SHOCK.

본 발명은 충격이 흡수되는 목발에 관한 것으로서, 더욱 상세하게는 사용자가 목발 사용시 보행 중에 지면으로부터 받게 되는 충격을 흡수하여 겨드랑이에 가해지는 압박을 최소화하고 통증 및 피로감을 감소시킬 수 있는 충격이 흡수되는 목발에 관한 것이다.The present invention relates to crutches in which impact is absorbed, and more particularly, to crutches in which a user absorbs shocks received from the ground during walking while using a crutch, thereby minimizing the pressure applied to the armpit and absorbing impacts capable of reducing pain and fatigue It is about crutches.

일반적으로 목발은 다리등, 하반신이 불편한 사람의 보행을 보조하기 위한 보조기구이다.In general, crutches are aids to assist people with lower back injuries such as legs.

이러한 목발은 지면에 닿고 일정 높이로 형성된 하단부재와, 하단부재의 상단에 연결되고 두 갈래로 상측으로 연장되는 상단부재와, 상단부재의 상단을 수평하게 연결하여 사용자의 겨드랑이에 끼워지는 지지부재와, 지지부재의 하측에 위치되어 상단부재를 상호 연결하고 사용자의 손에 파지되는 손잡이부재로 이루어져 있다.The crutches have a bottom member formed at a predetermined height and contacting with the ground, a top member connected to the top of the bottom member and extending bifurcated upward, a support member horizontally connected to the top of the top member, And a grip member which is positioned below the support member and interconnects the upper members and is gripped by a user's hand.

목발은 전체적으로 강도가 우수한 목재, 알루미늄재 또는 합성수지재로 제작되어 있다.Crutches are made entirely of wood, aluminum or synthetic resin with good strength.

사용자는 지지부재를 겨드랑이에 끼운 상태에서 손잡이부재를 파지하고 하단부재가 불편한 다리 대신에 지면을 지지하도록 하여 보행을 하게 된다. The user grasps the pull-tab in the state where the support member is fitted to the side, and the lower end member makes a walk by supporting the ground instead of the leg which is inconvenient.

이와 같이 목발을 사용하게 되면, 사용자의 체중이 목발에 전달되는데, 특히 겨드랑이에 끼워진 지지부재에 대부분이 전달된다, 따라서, 장시간동안 목발을 사용하게 될 경우, 겨드랑이 부위의 지속적인 압박으로 인해 통증이 유발되고, 심할 경우에는 요골신경을 압박하여 일시적인 근육마비를 유발하게 되는 문제점이 있었다.When the crutches are used, the weight of the user is transmitted to the crutches. In particular, when the crutches are used for a long period of time, the crutches are constantly pressed to cause pain And in severe cases, the radial nerve is compressed to cause temporary muscle paralysis.

따라서, 보행중에 전달되는 충격을 줄이기 위해 통상 탄성이 우수한 합성수지재를 목발의 하단부재의 끝단, 즉 지면에 닿는 부위에 장착하여 사용되고 있었다. 그러나, 완충부재인 합성수지재는 보행중에 가해지는 상당한 충격을 흡수하기에는 다소 한계가 있었다.Therefore, in order to reduce an impact transmitted during walking, a synthetic resin material having superior elasticity is generally used by being attached to the end of a lower end member of a crutch, that is, a portion contacting the ground. However, the synthetic resin material, which is a buffering member, has some limitations in absorbing a considerable impact during walking.

첨부한 도 1 내지 도 3을 참조하면, 본 발명에 따른 충격이 흡수되는 목발은 사용자의 겨드랑이에 끼워지는 지지부재(10)와, 지지부재(10)에 끼워지는 쿠션부재(20)와, 지지부재(10)의 양단을 각각 지지하는 한 쌍의 상단부재(30)와, 상단부재(30)의 중앙에 위치되어 사용자의 손에 파지되는 손잡이부재(40)와, 상단부재(30)에 연결되고 지면을 향하여 연장된 하단부재(50)와, 하단부재(50)의 끝단에 길이방향으로 슬라이딩되는 유동부재(60)와, 유동부재(60)를 소정 탄성력으로 지지하는 탄성부재(70)와, 유동부재(60)의 끝단에 끼워져 지면과의 충격을 흡수하도록 신축되는 신축캡(80)을 포함하여 이루어져 있다.1 to 3, a crutch for absorbing a shock according to the present invention comprises a support member 10 fitted to a side of a user, a cushion member 20 fitted to the support member 10, A pair of upper members 30 for supporting both ends of the member 10, a pull member 40 positioned at the center of the upper member 30 and gripped by a user's hand, A flow member 60 slidable in the longitudinal direction at the end of the lower member 50 and an elastic member 70 for supporting the flow member 60 with a predetermined elastic force, And a stretchable cap 80 which is fitted on an end of the flow member 60 and is stretchable and contractible so as to absorb an impact with the ground surface.

지지부재(10)는 사용자의 겨드랑이에 끼워질 수 있도록 충분한 길이로 형성되며, 단면이 원형 또는 각형인 바(BAR)가 사용된다. The support member 10 is formed to have a length sufficient to fit into the side of the user, and a bar (BAR) having a circular or square cross section is used.

지지부재(10)는 사용자의 체중이 전달되는 부분으로 한 쌍의 상단부재(30)에 의해 양측이 견고히 고정된다. The support member 10 is a portion to which a weight of the user is transmitted, and both sides are firmly fixed by the pair of upper members 30.

쿠션부재(20)는 지지부재(10)에 끼워져 구비되는 것으로 지지부재(10)에 체중이 실릴 때, 지지부재(10)에 의해 겨드랑이에 가해지는 충격을 흡수하게 된다. 이러한 쿠션부재(20)는 신축성 있는 재질인 우레탄폼 또는 고무재질로 제작된다.The cushion member 20 is fitted to the support member 10 and absorbs impact applied to the axle by the support member 10 when the weight is put on the support member 10. [ The cushion member 20 is made of a urethane foam or rubber material, which is a stretchable material.

쿠션부재(20)의 상면, 즉 겨드랑이에 접촉되는 면은 볼록하게 형성되고, 하면은 지지부재(10)에 끼우기 위해 길이방향으로 절개되고, 중앙에는 지지부재(10)가 인입되어 고정되는 인입홈이 형성되어 있다.The lower surface of the cushion member 20 is in contact with the upper surface of the cushion member 20, that is, the side surface thereof is convex. The lower surface of the cushion member 20 is cut in the longitudinal direction to fit the support member 10, Respectively.

상단부재(30)는 한 쌍이 구비되어 지지부재(10)의 양단에 각각 고정되고 타측은 지면을 향하여 연장되되 상호 이격된 거리가 점점 좁아지는 방향으로 경사지게 연장되어 상호 맞닿도록 형성된다.A pair of the upper members 30 are fixed to both ends of the support member 10, and the other ends of the upper members 30 extend toward the ground, and are spaced apart from each other and extend obliquely to each other to be mutually abutted.

손잡이부재(40)는 상단부재(30)의 중앙부분에 위치되고 지지부재(10)와 나란한 방향으로 상단부재(30)를 상호 연결하여 구비된다.The pull member 40 is located at the center portion of the upper member 30 and is provided by interconnecting the upper member 30 in a direction parallel to the support member 10. [

하단부재(50)는 상호 맞닿은 한 쌍의 상단부재(30)에 일측이 연결되고 타측은 지면을 향하여 일정 길이 연장되어 형성된다. 하단부재(50)의 타측면에는 중앙에 길이방향으로 일정 깊이만큼 패인 인입홈(51)이 형성되어 있다.The lower members 50 are connected to a pair of upper members 30 that are in contact with each other, and the other member is formed by extending a certain length toward the ground. The other side surface of the lower member 50 is formed with a lead-in groove 51 at the center at a predetermined depth in the longitudinal direction.

유동부재(60)는 인입홈(51)에 인입되어 슬라이딩되도록 구비된다. 인입홈(51)에는 탄성부재(70)가 내장되고, 유동부재(60)는 탄성부재(70)에 지지되어 소정 탄성력을 갖게 된다.The flow member (60) is provided to slide into the inlet groove (51). An elastic member 70 is embedded in the lead-in groove 51 and the flow member 60 is supported by the elastic member 70 to have a predetermined elastic force.

탄성부재(70)는 압축스프링이 사용된다.A compression spring is used as the elastic member (70).

인입홈(51)의 상면에는 인입홈(51)의 개구된 상면을 개폐하는 걸림판(52)이 구비되어 있다. 걸림판(52)은 중앙에는 유동부재(60)가 지나도록 관통되어 있다. 한편, 인입홈(51)에 인입되어 숨겨지는 유동부재(60)의 일단에는 방사상으로 돌출된 걸림돌기(61)가 형성되어 있다.On the upper surface of the lead-in groove 51, a holding plate 52 for opening and closing the upper surface of the lead-in groove 51 is provided. The stopper plate 52 is penetrated at its center so as to pass through the flow member 60. On the other hand, a locking protrusion 61 protruding in a radial direction is formed at one end of the flow member 60 which is drawn into the inlet groove 51 and is hidden.

이에, 유동부재(60)는 걸림돌기(61)가 걸림판(52)에 걸리는 구조이므로 탄성부재(70)에 의해 인입홈(51)으로부터 이탈되지 않게 된다.Therefore, the flow member 60 is not separated from the inlet groove 51 by the elastic member 70 because the latching protrusion 61 is caught by the latching plate 52.

신축캡(80)은 인입홈(51)으로부터 노출된 유동부재(60)의 타단에 구비된다. 신축캡(80)은 충격에 의해 신축되어 충격을 흡수하는 것으로 신축성있는 고무재질 및 우레탄폼으로 제조된다.The expansion and contraction cap 80 is provided at the other end of the flow member 60 exposed from the inlet groove 51. The retractable cap 80 is made of a stretchable rubber material and a urethane foam by absorbing impact by being stretched and contracted by an impact.

이와 같은 본 발명에 따른 충격이 흡수되는 목발은 사용자가 지지부재(10)를 겨드랑이에 끼우고 손잡이부재(40)를 파지한 상태에서 불편한 다리 대신 사용하게 된다.The crutches in which the impact according to the present invention is absorbed are used in place of the uncomfortable legs in a state in which the user holds the support member 10 on the side and grasps the pull-tab 40.

이때, 지면과 맞닿을 경우 충격이 발생되는데, 본 발명은 먼저, 유동부재(60)의 신축캡(80)이 수축되면서 충격이 흡수된다. 그리고 두번째로 유동부재(60)가 탄성부재(70)를 가압하여 후퇴되면서 탄성부재(70)의 탄성력에 의해 충격이 흡수된다. 마지막으로 지지부재(10)에 구비된 쿠션부재(20)가 수축되면서 충격이 흡수된다.At this time, an impact occurs when it comes into contact with the paper surface. In the present invention, first, the expansion and contraction cap 80 of the flow member 60 contracts and the impact is absorbed. Secondly, the impact is absorbed by the elastic force of the elastic member 70 while the flow member 60 is retracted by pressing the elastic member 70. Finally, the cushion member 20 provided in the support member 10 is contracted to absorb the impact.

따라서, 본 발명은 지면과의 접촉으로 발생되는 충격을 3차에 걸쳐 흡수하게 되므로 효과적으로 충격을 흡수하게 된다.Therefore, the present invention absorbs the impact generated by the contact with the ground three times, effectively absorbing the impact.
