이와같은 기술과 관련되어 종래의 대한민국 특허 제422466호에 완충형 캐스터의 기술이 제시되고 있으며 그 구성은 도1에서와 같이, 탑플레이트(110)의 중앙부에는 탑핀(120)이 결합ㆍ고정되고, 상기 탑플레이트(110)의 하측으로 돌출된 탑핀(120)의 부위에는 전면 및 저면이 개방된 요크(130)가 결합되는데, 탑핀(120)의 하단부에는 요크(130)가 탑핀(120)으로부터 이탈되는 것을 방지하는 너트(171)가 체결된다.In connection with such a technique, a technique of a buffer type caster is proposed in Korean Patent No. 422466. The configuration of the top pin 110 is coupled and fixed to the center of the top plate 110, as shown in FIG. A portion of the top pin 120 protruding to the bottom of the top plate 110 is coupled to the yoke 130 having the front and bottom surfaces open, and the yoke 130 is separated from the top pin 120 at the lower end of the top pin 120. The nut 171 which is prevented from becoming is fastened.
그리고, 상기 탑핀(120)이 관통하는 탑플레이트(110)와 요크(130)의 부위에는 하측함몰부(111) 및 상측함몰부(135)가 각각 형성되고, 상기 요크(130)의 원활한 회전을 도와주는 상부베어링(173)이 하측함몰부(111) 및 상측함몰부(135)와 접촉되어 설치되고, 상기 상부베어링(173)은 상면이 개방된 상부먼지덮개(175)에 의하여 보호되며, 상기 상부먼지덮개(175)의 상단면과 인접하는 탑플레이트(110)에는 하측으로 돌출된 테 형상의 엠보싱(113)이 형성되어 탑플레이트(110)의 저면과 상부먼지덮개(175)의 상단면 사이로 이물질이 유입되는 것을 방지한다.In addition, a lower recess 111 and an upper recess 135 are respectively formed at the top plate 110 and the yoke 130 through which the top pin 120 penetrates, thereby smoothly rotating the yoke 130. The upper bearing 173 is provided in contact with the lower recess 111 and the upper recess 135, and the upper bearing 173 is protected by the upper dust cover 175 having an open upper surface. The top plate 110 adjacent to the top surface of the upper dust cover 175 is formed with an embossing 113 having a rim shape protruding downwardly between the bottom surface of the top plate 110 and the upper surface of the upper dust cover 175. Prevent foreign matter from entering
또한, 상기 요크(130)와 너트(171) 사이의 탑핀(120)의 부위에는 하부베어링(177)과 하부베어링(177)을 감싸서 보호하는 하부먼지덮개(179)가 설치되고, 상기 요크(130)의 양측면 내측에는 쌍을 이루는 아암(140)의 일단부측이 지지되고, 상기 아암(140)의 타단부측은 요크(130)의 외측으로 노출되며, 상기 아암(140)의 타단부측에는 바닥과 접촉되어 회전축(151)을 중심으로 회전하는 휠(150)이 결합되며, 상기 아암(140)에는 완충부재(160)가 지지되는 구성으로 이루어 진다.In addition, a portion of the top pin 120 between the yoke 130 and the nut 171 is provided with a lower dust cover 179 to protect the lower bearing 177 and the lower bearing 177, and the yoke 130 One end side of the paired arm 140 is supported inside both sides of the side, and the other end side of the arm 140 is exposed to the outside of the yoke 130, the other end side of the arm 140 in contact with the bottom The wheel 150 is rotated about the rotating shaft 151 is coupled, the arm 140 is made of a configuration in which the buffer member 160 is supported.
그러나, 상기와 같은 완충형 캐스터는, 충격만을 흡수하는 구성으로 휠에 전해지는 충격의 강도 정도는 측정할 수 없어 무리한 하중의 전달 등에 의해 운반이 힘들게 되거나 캐스터가 파손되는 등의 문제점이 있는 것이다.However, the buffer type caster as described above has a problem such that the strength of the impact transmitted to the wheels cannot be measured because the shock absorber is configured to absorb only the impact, so that it is difficult to transport or the caster is damaged due to excessive load transfer.
한편, 현대 사회에서 큰 문제로 대두되는 노인요양원이나 요양병원 또는 노인지정병원 등의 치매증상을 가지고 있는 환자들은 병실을 단순 모니터링하는 경우가 대부분이며, 담당 의사나 간호사들이 이들과 함께 생활하면서 돌보고 있으나, 환자가 담당의사나 간호사 등이 관리가 소홀한 틈에 치매환자 스스로가 배회하는 경우 등이 발생하게 되어 큰 사고로 이어지는 경우가 발생하기도 한다.On the other hand, patients with dementia symptoms such as elderly nursing homes, nursing homes, or designated hospitals, which are a major problem in the modern society, are usually monitored by the doctors and nurses while they are living with them. In some cases, the patient may wander around when the doctor or nurse neglects management, leading to a major accident.
이를 방지하기 위하여 치매환자에게 위치확인 추적 단말기 등을 보급하여 환자가 배회하는 위치를 추적하고 있는데, 이런 방법 또한 보호가 시시각각 필요한 치매환자에게 즉각적인 조치라고 보기는 어려우며, 치매환자의 경우 소지해야할 단말기를 빈번히 분실 혹은 파손하게 될 위험성이 크며, 단말기를 분실한 경우에 적절한 조치를 취하지 못하고 배회환자를 방치시키는 문제점이 지적되고 있는 것이다.In order to prevent this, a tracking device is provided to patients with dementia to track the location of patients roaming.However, this method is also difficult to see as an immediate measure for dementia patients who need protection at any time. There is a high risk of frequent loss or damage, and it is pointed out that the problem of leaving the roaming patients without taking appropriate measures when the terminal is lost.
