연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

An apparatus comprises a frame and a transport assembly supporting the frame. The transport assembly is configured to selectively move relative to the frame between a transport position and a brake position. A portion of the frame frictionally engages a portion of the transport assembly in the brake position to affect a brake application that resists the transportation of the frame. The portion of the frame is disengaged from the portion of the transport assembly in the transport position to allow for transportation of the frame.

1. An apparatus comprising: a frame, anda transport assembly supporting the frame, the frame being configured to selectively move relative to the transport assembly between a transport position and a brake position, the transport assembly including a rotational element comprising a first engagement surface and a second engagement surface adjacent to the first engagement surface, the first engagement surface and the second engagement surface both extend along the entire circumference of the rotational element, the first engagement surface being configured to engage the floor and the second engagement surface being configured to frictionally engage the frame in the brake position and be disengaged from the frame in the transport position. 2. The apparatus of claim 1, wherein the rotational element includes a wheel and the first engagement surface extends along a first circumferential edge of the wheel and the second engagement surface extends along a second circumferentially edge of the wheel. 3. The apparatus of claim 1, wherein the second engagement surface does not engage the floor. 4. A patient support apparatus comprising: a lower frame,a lift mechanism coupled to the lower frame;an upper frame coupled to the lift mechanism and movable with respect to the lower frame in response to the movement of the lift mechanism;an actuator assembly coupled to the frame,and a caster assembly supporting the frame and configured to movably engage the frame and the actuator assembly, the actuator assembly is configured to cooperate with the caster assembly and frame to selectively allow the frame to move relative to the caster assembly between a first position and a second position, a portion of the caster assembly being frictionally engaged by a portion of the frame to resist rotation of the portion of the caster assembly in the first position and the portion of the caster assembly being disengaged from the portion of the frame in the second position. 5. The apparatus of claim 4, wherein the actuator assembly includes a cam shaft that rotatably engages the portion of the caster assembly to move the caster assembly with respect to the frame as the cam shaft is rotated, the cam shaft including at least one of a recessed portion and a raised portion that engages the caster assembly. 6. The apparatus of claim 4, wherein the transport assembly includes a rotational element with an engagement surface, wherein the engagement surface is configured to contact a support surface in the transport position and wherein the engagement surface is configured to frictionally contact the portion of the frame and the support surface in the brake position. 7. The apparatus of claim 6, wherein the rotational element is aligned angularly with respect to the frame, and wherein the engagement surface includes a first portion and a second portion, the first portion of the engagement surface being configured to contact the support surface and the second portion of the engagement surface being configured to frictionally contact the portion of the frame, the first portion and the second portion are different portions of the engagement surface. 8. The apparatus of claim 7, wherein the first portion does not contact the frame in the brake position and the second portion does not contact the support surface in the transport position. 9. A patient support apparatus comprising: a frame,a non-elastic biasing assembly coupled to the frame,and a caster assembly supporting the frame and configured to movably engage the frame and the non-elastic biasing assembly, the non-elastic biasing assembly, when actuated, is configured to cooperate with the caster assembly and frame to selectively allow the frame to move the frame relative to the caster assembly between a first position and a second position, a portion of the caster assembly being frictionally engaged by a portion of the frame to resist rotation of the portion of the caster assembly in the first position and the portion of the caster assembly being disengaged from the portion of the frame in the second position. 10. The patient support apparatus of claim 9, wherein the caster assembly includes a caster shaft and a wheel coupled to the caster shaft, wherein the wheel is substantially parallel to a portion of the caster shaft. 11. The patient support apparatus of claim 9, wherein the caster assembly includes a caster shaft and a wheel coupled to the caster shaft, wherein the wheel is at an angle with respect to the caster shaft, the wheel including an engagement surface wherein a first portion of the engagement surface is configured to contact a floor and a second portion of the engagement surface is configured to frictionally contact the portion of the frame, the first portion and the second portion are different portions of the engagement surface. 12. The patient support apparatus of claim 11, wherein the first portion is along an edge of the engagement surface and the second portion is along another edge of the engagement surface wherein the first portion does not contact the frame and the second portion does not contact the floor. 13. The patient support apparatus of claim 9, wherein the frame includes a bore, a portion of the caster assembly being positioned within the bore, a retaining element being configured to couple with the portion of the caster assembly positioned within the bore and configured to couple with a portion of the bore to removably retain the portion of the caster assembly within the bore. 14. The patient support apparatus of claim 9, wherein the non-elastic biasing includes a non-elastic biasing selected from the group of non-elastic biasing consisting of a pneumatic actuator, a linear actuator, a rotary actuator, a hydraulic actuator, a motor, a servomechanism, a manual crank, a lever, and a foot pedal. 15.
