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.

An angle adjustment assembly comprises a first member configured to pivot about a first axis. A second member is configured to rotate about a second axis transverse to the first axis. The first member is eccentrically supported in relation to the second member so that rotation of the second member produces pivotal movement of the first member. A third member may be configured to rotate about a third axis transverse to the first axis. The second member may be eccentrically supported in relation to the third member so that rotation of the third member further produces pivotal movement of the first member. The second member may comprise an inner cam member. The third member may comprise an outer cam member. The first member may be a caster stem for supporting a wheelchair caster assembly, or alternatively, an axle receiver for supporting an axle of a wheelchair drive wheel.

1. An angle adjustment assembly comprising: a first member configured to pivot about a first axis,at least a second member configured to rotate about a second axis transverse to the first axis, the first member being eccentrically supported in relation to the second member so that rotation of the second member produces pivotal movement of the first member, andat least a third member configured to rotate about a third axis transverse to the first axis, the second axis not aligning with the third axis, the second member being eccentrically supported in relation to the third member so that rotation of the third member further produces pivotal movement of the first member,wherein the first member comprises a medial portion defining a ball that fits within a socket defined by the inner cam member, andwherein the second member is an inner cam member and the third member is an outer cam member, the inner cam member being in a nesting relationship with the outer cam member. 2. An angle adjustment assembly comprising: a first member configured to pivot about a first axis,at least a second member configured to rotate about a second axis transverse to the first axis, the first member being eccentrically supported in relation to the second member so that rotation of the second member produces pivotal movement of the first member, anda pivot bushing comprising a clevis comprising a pair of opposing legs joined together by a transverse member, wherein the first member fits snuggly for pivotal movement between the opposing legs,wherein the first member comprises a partially cylindrical-shaped proximal portion at a proximal end thereof and the pivot bushing comprises a first cam surface engaging a proximal end of the proximal portion and a second cam surface engaging a distal end of the proximal portion, the first and second cam surfaces cooperatively capturing the proximal portion therebetween. 3. An angle adjustment assembly comprising: a first member configured to pivot about a first axis,at least a second member configured to rotate about a second axis transverse to the first axis, the first member being eccentrically supported in relation to the second member so that rotation of the second member produces pivotal movement of the first member,a pivot bushing comprising a clevis comprising a pair of opposing legs joined together by a transverse member, wherein the first member fits snuggly for pivotal movement between the opposing legs, the opposing legs being provided with holes that are arranged and configured to align with holes in opposing walls of a wheelchair tube, the proximal portion having at least one threaded hole passing therethrough and aligning with the holes in the opposing legs and holes in the wheelchair tube, andat least one fastener passing through the holes in the wheelchair tube and the holes in the opposing legs and threaded into the at least one threaded hole, the at least one fastener functions as a pivot dowel about which the first member may pivot about a lateral axis. 4. An angle adjustment assembly comprising: a first member configured to pivot about a first axis,at least a second member configured to rotate about a second axis transverse to the first axis, the first member being eccentrically supported in relation to the second member so that rotation of the second member produces pivotal movement of the first member, andat least a third member configured to rotate about a third axis transverse to the first axis, the second axis not aligning with the third axis, the second member being eccentrically supported in relation to the third member so that rotation of the third member further produces pivotal movement of the first member,wherein the second member is an inner cam member and the third member is an outer cam member, wherein the first member is eccentrically supported in relation to the inner cam member and the inner cam member is eccentrically supported in relation to the outer cam member, andwherein a proximal end of the first member is supported for pivotal movement by a pivot bushing, which is dimensioned and configured to be supported in relation to a wheelchair tube. 5. The angle adjustment assembly of claim 4, wherein the first member is a caster stem, and a distal end of the caster stem is configured to operatively support a caster wheel in relation to the wheelchair tube. 6. The angle adjustment assembly of claim 4, wherein the first member is an axle receiver, and a distal end of the axle receiver is configured to operatively support a wheelchair drive wheel in relation to the wheelchair tube. 7. An angle adjustment assembly supporting a component in relation to a wheelchair, comprising: a pivot bushing dimensioned and configured to be inserted within an open end of a wheelchair tube,an inner cam member,an outer cam member comprising: a one-piece clamping collar having a side wall with a slot therein, anda fastener passing through a hole in a first side wall portion of the collar, traversing the slot, and threading into a threaded hole in a second side wall portion of the collar, anda pivotal member having a proximal end dimensioned and configured to be supported for pivotal movement within the pivot bushing and a medial portion of the pivot member cooperating with the outer and inner cam members to selectively hold an axle receiver at a desired angle,wherein the inner cam member is eccentrically supported within the outer cam member, and the pivotal member is eccentrically supported within the inner member, and wherein rotational movement of the outer and inner cam members in relation to one another pivotally displaces the pivotal member in relation to the pivot bushing, andwherein tightening the fastener causes the side wall of the collar to move radially inward, and thus clamp against the inner cam member to releasably hold the pivotal member in a desired position. 8. The angle adjustment assembly of claim 7, wherein the pivot bushing comprises a clevis, comprising a pair of opposing legs, joined together by a transverse member, each leg comprising an outer surface, which may be curved to conform to an inner surface of the wheelchair tube, for a snug fit therein. 9. The angle adjustment assembly of claim 8, wherein the proximal end of the pivotal member comprises opposing flats, which form bearing surfaces for engagement with the opposing legs of the pivot bushing. 10. The angle adjustment assembly of claim 9, wherein the pivotal member comprises a caster stem, which is configured to support a wheelchair caster assembly. 11. The angle adjustment assembly of claim 9, wherein the pivotal member comprises an axle receiver, which is configured to receive an axle of a wheelchair drive wheel. 12. The angle adjustment assembly of claim 7, wherein the medial portion of the pivotal member defines a ball that fits within a socket defined by the inner cam member, the ball being press fit into the socket. 13. The angle adjustment assembly of claim 7, wherein the outer and inner cam members each have associated therewith a thumbwheel, which comprises a ribbed periphery.
