Description

노약자용 안전보행기Safety walkers for the elderly
본 발명은 노약자용 안전보행기에 관한 것으로, 구체적으로는 기존의 바퀴와 더불어 한쪽에 편심바퀴를 달아 사고를 방지하기 위한 노약자용 안전보행기에 관한 것이다.The present invention relates to a safety walker for the elderly, and more particularly, to a safety walker for the elderly to prevent accidents by attaching an eccentric wheel on one side in addition to the existing wheels.
도 1은 기존의 노약자용 보행기의 일반적인 예를 보여준다. 가장 널리 사용되는 기존의 보행기는 2개의 앞바퀴를 이용하는 것으로, 정지상태에서는 뒷쪽 프레임의 하단부에 달린 고무패킹(1)을 지면에 둔다.1 shows a general example of a conventional walker for the elderly. The most widely used conventional walker uses two front wheels, and in a stationary state, a rubber packing (1) attached to the lower end of the rear frame is placed on the ground.
이런 보행기를 사용하면서 노약자가 보행을 하려면 사용자가 뒷쪽 프레임을 들고 앞바퀴를 밀면서 움직이거나, 고무패킹(1)을 지면에 댄채 밀면서 움직여야 한다. 전자의 경우, 급격한 구름운동으로 보행자, 보행기가 노약자의 운동능력을 벗어나 갑자기 앞으로 움직여 노약자가 넘어져 다치는 사고가 자주 발생한다. 또한, 고무패킹(1)을 지면에 댄채 보행기를 움직일 경우, 지면과의 마찰로 인해 바닥면에 흔적이 남거나 바닥면이 손상될 수 있음은 물론, 보행자가 쉽게 움직이지 못해 힘이 든다는 문제가 있다.In order for the elderly to walk while using such a walker, the user must move while holding the rear frame and pushing the front wheel, or while pushing the rubber packing (1) on the ground. In the former case, accidents often occur in which pedestrians and walker suddenly move forward beyond the motor skills of the elderly due to rapid cloud movement, causing the elderly to fall and injure themselves. In addition, when moving the walker with the rubber packing (1) on the ground, there is a problem that a trace may be left on the floor surface or the floor surface may be damaged due to friction with the ground, as well as a problem that the pedestrian cannot easily move and it is difficult. .
본 발명은 종래의 이런 문제점을 감안하여 안출된 것으로, 사용자가 보행기의 한쪽을 들지 않고도 보행기를 움직일 수 있으면서도, 보행기가 갑자기 급격하게 움직이는 것을 방지하여 보행자의 안전을 확보함은 물론, 바닥면이 손상되거나 마찰되는 것을 방지하는 안전보행기를 제공하는 것을 목적으로 한다.The present invention was conceived in consideration of such problems in the prior art, and while the user can move the walker without lifting one side of the walker, it prevents the walker from moving suddenly and suddenly, thereby ensuring the safety of the pedestrian, as well as damaging the floor surface. The purpose of this is to provide a safety walker that prevents damage or friction.
이런 목적 달성을 위해 본 발명은, 3개 이상의 다수의 세로 지지대(11)와 상단부에 겨드랑이 받침대나 양쪽 손잡이(13)를 갖추고, 전방 세로지지대(11)의 하단부에 원형 앞바퀴(15)가 달려있는 노약자용 안전보행기에 있어서:In order to achieve this object, the present invention is provided with three or more vertical supports 11 and armpit supports or both handles 13 at the upper end, and circular front wheels 15 are attached to the lower end of the front vertical supports 11 For safety walkers for the elderly:
후방 세로지지대(11)의 하단부에 편심 회전운동을 하는 편심바퀴(20)가 달려있고;An eccentric wheel 20 for eccentric rotation is attached to the lower end of the rear vertical support 11;
상기 편심바퀴(20)의 회전축(30)이 편심바퀴(20)의 기하학적 중심(C)에서 편심거리(d)만큼 벗어나 있는 노약자용 안전보행기를 제공한다. It provides a safety walker for the elderly in which the rotation shaft 30 of the eccentric wheel 20 deviates from the geometric center C of the eccentric wheel 20 by an eccentric distance d.
본 발명은 또한, 3개 이상의 다수의 세로 지지대(11)와 상단부에 겨드랑이 받침대나 양쪽 손잡이(13)를 갖추고, 전방 세로지지대(11)의 하단부에 원형 앞바퀴(15)가 달려있는 노약자용 안전보행기에 있어서:The present invention also includes three or more vertical supports 11 and armpit supports or both handles 13 at the upper end, and a safety walker for the elderly with a circular front wheel 15 at the lower end of the front vertical support 11 In:
후방 세로지지대(11)의 하단부에 편심 회전운동을 하는 편심바퀴(20)가 달려있고;An eccentric wheel 20 for eccentric rotation is attached to the lower end of the rear vertical support 11;
상기 편심바퀴(20)의 회전축(30)이 편심바퀴(20)의 기하학적 중심(C)과 일치하되, 편심바퀴(20)의 원주면에 하나 이상의 평면부(22)가 형성된 노약자용 안전보행기를 제공한다. The rotation shaft 30 of the eccentric wheel 20 coincides with the geometric center C of the eccentric wheel 20, but at least one flat portion 22 is formed on the circumferential surface of the eccentric wheel 20. to provide.
본 발명은 또한, 3개 이상의 다수의 세로 지지대(11)와 상단부에 겨드랑이 받침대나 양쪽 손잡이(13)를 갖추고, 전방 세로지지대(11)의 하단부에 원형 앞바퀴(15)가 달려있는 노약자용 안전보행기에 있어서:The present invention also includes three or more vertical supports 11 and armpit supports or both handles 13 at the upper end, and a safety walker for the elderly with a circular front wheel 15 at the lower end of the front vertical support 11 In:
후방 세로지지대(11)의 하단부에 편심 회전운동을 하는 편심바퀴(20)가 달려있고;An eccentric wheel 20 for eccentric rotation is attached to the lower end of the rear vertical support 11;
상기 편심바퀴(20)의 회전축(30)이 편심바퀴(20)의 기하학적 중심(C)과 일치하되, 측면에서 본 편심바퀴(20)의 형상이 원형이 아니라 타원형인 노약자용 안전보행기도 제공한다.The rotation shaft 30 of the eccentric wheel 20 coincides with the geometric center C of the eccentric wheel 20, but the shape of the eccentric wheel 20 viewed from the side is not circular, but an elliptical safety pedestrian is also provided. .
본 발명에 있어서, 전술한 편심바퀴(20)의 회전축(30)이 편심바퀴(20)의 기하학적 중심(C)에서 편심거리(d)만큼 벗어나 있을 수 있다.In the present invention, the rotation shaft 30 of the eccentric wheel 20 may be deviated from the geometric center C of the eccentric wheel 20 by an eccentric distance d.
이 경우, 편심거리(d)의 크기를 조절할 수 있으면 바람직할 것이다.In this case, it would be desirable if the size of the eccentric distance (d) can be adjusted.
이와 같이 구성된 본 발명의 안전보행기에 의하면, 편심바퀴가 원운동을 하지 않기 때문에 보행기가 갑자기 급하게 움직이는 것을 미연에 방지함으로써, 노약자인 사용자가 보행기를 사용함으로써 생길 수 있는 안전사고를 방지할 수 있다.According to the safety walker configured as described above, since the eccentric wheel does not perform circular motion, the walker is prevented from moving suddenly and suddenly, thereby preventing a safety accident that may occur when the elderly user uses the walker.
또한, 보행기가 바닥면과 마찰을 일으키지 않기 때문에, 보행기가 사용되는 바닥면의 손상을 방지할 수 있다.In addition, since the walker does not cause friction with the floor surface, damage to the floor surface on which the walker is used can be prevented.

도 2는 본 발명에 따른 노약자용 안전보행기(10)의 사시도이고, 도 3은 편심바퀴(20)의 2가지 예를 보여주는 측면도들이다.Figure 2 is a perspective view of the safety walker 10 for the elderly according to the present invention, Figure 3 is a side view showing two examples of the eccentric wheel (20).
본 실시예의 안전보행기(10)는 4개의 세로지지대(11)와 상단부의 좌우측의 양쪽 손잡이(13)를 기본 구성으로 하지만, 필요에 따라서는 세로지지대(11)가 3개만 있을 수도 있다. 또한, 손잡이 대신에 겨드랑이 받침대가 구비될 수도 있다.The safety walker 10 of this embodiment has four vertical supports 11 and both handles 13 on the left and right sides of the upper portion as a basic configuration, but if necessary, there may be only three vertical supports 11. In addition, an armpit support may be provided instead of the handle.
4개의 세로지지대(11) 중 앞쪽의 전방 세로지지대(11)의 하단부에는 원형 앞바퀴(15)가 달려있다. 즉, 전방 세로지지대에 달려있는 앞바퀴(15)는 원운동을 하는 바퀴가 일반적이지만, 도시된 바와 같이, 편심바퀴의 회전축과 기하학적 중심을 일치시켜서 원운동을 하도록 할 수도 있다.A circular front wheel (15) is attached to the lower end of the front vertical support (11) among the four vertical supports (11). That is, the front wheel 15, which is mounted on the front vertical support, is generally a wheel that performs circular motion, but, as shown, the rotation axis of the eccentric wheel and the geometric center may be matched to perform circular motion.
반면에, 2개의 후방 세로지지대(11)의 하단부에는 편심 회전운동을 하는 편심바퀴(20)가 달리게 된다. On the other hand, at the lower end of the two rear vertical supports 11, an eccentric wheel 20 for eccentric rotational motion runs.
"편심"의 사전적 의미는 회전체의 회전축이 기하학적 중심과 일치하지 않는 것을 의미하지만, 본 명세서에서는 설명의 편의상 광의의 의미로, "편심바퀴"란 회전체의 회전축과 기하학적 중심이 일치되지만 원운동을 하지 않는 캠이나 타원형의 바퀴는 물론, 원형 바퀴의 원주면에 하나 이상의 평면부가 형성되어 연속적인 원운동을 하지 않는 바퀴를 총칭하는 표현으로 해석한다.The dictionary meaning of "eccentric" means that the rotation axis of the rotating body does not coincide with the geometric center, but in this specification, in a broad sense for convenience of description, the "eccentric wheel" is a circular It is interpreted as a generic expression for a cam or elliptical wheel that does not move, as well as a wheel that does not perform continuous circular motion by forming one or more flat parts on the circumference of the circular wheel.
도 3에 도시된 바와 같이, 본 발명의 편심바퀴(20)의 회전축(30)은 편심바퀴(20)의 기하학적 중심(C)에서 편심거리(d)만큼 벗어나 있는 것이 일반적이다. 보행기(10)를 사용하는 노약자의 상태에 따라, 편심거리(d)를 사용자가 편리하게 사용할 수 있도록 조정할 수 있다. As shown in FIG. 3, the rotation shaft 30 of the eccentric wheel 20 of the present invention is generally deviated from the geometric center C of the eccentric wheel 20 by an eccentric distance d. Depending on the state of the elderly using the walker 10, the eccentric distance (d) can be adjusted so that the user can conveniently use.
즉, 도 3A와 같이, 사용자의 건강상태가 좋지 않을 경우 편심거리(d)를 짧게 하면 적은 힘으로도 편심바퀴(20)를 쉽게 회전시킬 수 있다. 또, 도 3B와 같이, 사용자의 건강상태가 비교적 좋을 경우, 편심거리(d)를 길게 하면 편심바퀴(20)가 쉽게 회전하지 않아 사용자가 더 큰 힘을 주어야만 편심바퀴(20)가 회전할 수 있게 된다. 물론, 이 경우에는 보행기(10)의 정지상태에서의 안정성과 이동중의 안정성은 더 높아질 것이다.That is, as shown in FIG. 3A, if the eccentric distance d is shortened when the user's health is not good, the eccentric wheel 20 can be easily rotated with little force. In addition, as shown in Fig. 3B, when the user's health is relatively good, if the eccentric distance d is increased, the eccentric wheel 20 does not easily rotate, so that the eccentric wheel 20 can rotate only when the user applies a greater force. There will be. Of course, in this case, the stability of the walker 10 in a stationary state and stability during movement will be higher.
도 4는 본 발명의 편심바퀴(20)의 다른 예, 즉 회전축과 기하학적 중심이 일치하는 경우의 다양한 실시예를 보여주는 측면도이다. 4 is a side view showing another example of the eccentric wheel 20 of the present invention, that is, various embodiments when the rotation axis and the geometric center coincide.
도 4A에 도시된 편심바퀴(20)는 원주면의 한 부분이 평면부(22)인 예를 보여준다. 이와 같이, 한 부분이 평면부(22)일 경우 편심바퀴(20)가 원활한 원운동을 하지 않고 평면부(22)가 지면과 접촉할 때 보행기(10)가 일단 정지되는 효과가 생긴다. The eccentric wheel 20 shown in FIG. 4A shows an example in which a part of the circumferential surface is a flat part 22. In this way, when one part is the flat part 22, the eccentric wheel 20 does not perform smooth circular motion, and the walker 10 is once stopped when the plane part 22 contacts the ground.
도 4B는 평면부(22)가 180도 각도로 2개, 4C는 평면부(22)가 120도 각도로 3개, 4D는 평면부가 90도 각도로 4개 형성된 예를 보여준다.4B shows an example in which two flat portions 22 are formed at an angle of 180 degrees, 4C shows an example in which three flat portions 22 are formed at an angle of 120 degrees, and 4D shows an example in which four flat portions are formed at an angle of 90 degrees.
사용자의 상태에 따라, 적절한 갯수의 평면부(22)가 형성된 편심바퀴(20)를 사용하면 된다. 경우에 따라서는, 편심부가 5개 이상인 다각형 바퀴를 사용할 수도 있다.Depending on the user's condition, an appropriate number of eccentric wheels 20 may be used. In some cases, a polygonal wheel having five or more eccentric portions may be used.
도 4E는 편심바퀴(20)를 측면에서 본 형상이 원형이 아닌 타원형인 경우이다. 이런 편심바퀴(20)는 타원형은 물론 일반적인 캠 형상, 즉 곡률반경이 다른 2개 이상의 부분으로 이루어진 형상을 취할 수 있다. 이 경우에도, 회전축이 기하학적 중심에서 편심거리 d만큼 벗어난 곳에 위치할 수 있다. 이 때는, 보행기의 안전성이 더 강화될 것이다.4E is a case in which the eccentric wheel 20 is viewed from the side and has an elliptical shape rather than a circular shape. This eccentric wheel 20 may take a shape consisting of two or more parts having different radiuses of curvature, as well as an oval shape. Even in this case, the axis of rotation may be located at a location deviating from the geometric center by an eccentric distance d. In this case, the safety of the walker will be further strengthened.
도 4F는 원주부에 평면부, 구체적으로는 2개의 평면부가 형성된 편심바퀴(20)에 기하학적 중심이 아닌 곳에 2개의 회전축(30)이 형성된 예를 보여준다. 이 실시예의 경우, 사용자가 자신에 맞는 회전축(30)을 선택하여 편심바퀴(20)를 회전시킬 수 있는데, 이 경우 전술한 어떤 실시예보다 더 많은 힘을 가해야 할 것이고, 보행기의 안전성은 더 강화될 것이다. 4F shows an example in which two rotation shafts 30 are formed in a non-geometric center of the eccentric wheel 20 in which a flat portion, specifically, two flat portions, is formed on the circumference. In this embodiment, the user can rotate the eccentric wheel 20 by selecting the rotation shaft 30 suitable for him. In this case, more force must be applied than any of the above-described embodiments, and the safety of the walker is more Will be strengthened.
이상 설명한 실시예에서, 편심거리(d)는 사용자의 체력이나 사용상의 편의성에 맞게 적절히 조절할 수 있다.In the above-described embodiment, the eccentric distance d may be appropriately adjusted to suit the user's physical strength or convenience in use.
또한, 앞바퀴는 일반 바퀴를 사용하고, 뒷바퀴는 편심바퀴를 사용한 예를 들어 설명하였지만, 필요에 따라서는, 앞바퀴를 편심바퀴로 사용할 수도 있고, 바퀴 전체를 편심바퀴로 사용할 수도 있다. 또한, 바퀴 자체가 선회할 수 있도록, 필요에 따라서는 편심바퀴를 포함한 바퀴에 선회구를 설치할 수도 있다.In addition, a general wheel is used as the front wheel and an eccentric wheel is used as the rear wheel.
