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

A wheel mount assembly adapted for use in securing a camber tube to a wheelchair frame comprises an axle plate, at least one axially displaceable member adapted to be fixed in relation to the axle plate, and at least one radially displaceable member adjacent the axially displaceable members. The axially displaceable member is adapted to be axially displaced to cause the radially displaceable member to be displaced to tighten against the camber tube to hold the camber tube in place.

1. A wheel mount assembly for use securing a camber tube to a wheelchair frame, the wheel mount assembly comprising:an axle plate;at least one axially displaceable member adapted to be fixed in relation to the axle plate; andat least one radially displaceable member adjacent the axially displaceable member, the axially displaceable member being adapted to be axially displaced to cause the radially displaceable member to be displaced to tighten against the camber tube to hold the camber tube in place.2. The wheel mount assembly according to claim 1, wherein the axially displaceable member is a compression plate and the radially displaceable member is a ring shaped compression sleeve that is adapted to be compressed by the compression plate.3. The wheel mount assembly according to claim 2, wherein the compression sleeve has a hole and the compression plate has a filleted bore, the camber tube being adapted to pass through the hole in the compression sleeve and through the filleted bore in the compression plate.4. The wheel mount assembly according to claim 3, wherein the compression sleeve and compression plate are wedge shaped such that the compression sleeve compresses against the compression plate and locks the camber tube as the compression plate is displaced.5. The wheel mount assembly according to claim 1, wherein the axially displaceable member is a compression plate each having a central bore and the radially displaceable member is a wedge shaped tooth, the central bore of the compression plate being filleted, the compression plate being adapted to be displaceable toward the wedge shaped tooth to clamp the wedge shaped tooth against filleted bore to hold the camber tube in place.6. The wheel mount assembly according to claim 1, wherein the axially displaceable member is threaded collar with internal threads and the radially displaceable member is a compression sleeve with external threads, the threaded collar being adapted to tighten onto the compression sleeve to force the sleeve against the camber tube and hold the camber tube in place.7. The wheel mount assembly according to claim 1, wherein the axially displaceable member is a compression plate and the radially displaceable member is an O-ring that is adapted to be compressed by the compression plate against the camber tube and hold the camber tube in place.8. A wheel mount assembly for use in mounting a rear wheel to the frame of a wheelchair, the wheel mount assembly comprising:an axle plate that is adapted to be attached to a wheelchair frame; anda clamp assembly adapted to be supported by the axle plate, the clamp assembly comprising:at least one axially displaceable member; andat least one radially displaceable member adjacent the axially displaceable member, displacement of the axially displaceable member causes the radially displaceable member to tighten against the camber tube to hold the camber tube in place relative to the axle plate.9. The assembly according to claim 8 wherein the axle plate has a mount for attaching the axle plate to a tubular wheelchair frame.10. The assembly according to claim 9 wherein the mount is in the form of a saddle having a series of holes that are adapted to align with similarly spaced holes in the wheelchair frame to allow the axle plate to be mounted at various fore/aft positions on the wheelchair frame.11. The assembly according to claim 8 further comprising a slot in the axle plate to allow the camber tube to be moved up or down within the axle plate in order to position the camber tube at a desired height.12. The assembly according to claim 8 wherein the at least one axially displaceable member includes a pair of spaced compression plates and the at least one radially displaceable member includes a compression sleeve between the compression plates.13. The assembly according to claim 12 wherein the compression plates are mounted to the axle plate using fasteners that are adapted to be threaded into mating tapped holes in the axle plate.14. The assembly according to claim 13 wherein the mating tapped holes include a vertical series of tapped holes that allow the compression plates to mount at various vertical positions, thus permitting the rear wheel to be positioned at different heights.15. The assembly according to claim 12 wherein the compression sleeve is provided with two chamfered edges that are adapted to mate with fillets on an inner diameter of the compression plates, which are adapted to squeeze the compression sleeve, causing radial deformation of the compression sleeve to force the compression sleeve to close around the camber tube, thus locking the camber tube in a fixed position.16. The assembly according to claim 12 wherein a slit is provided in the compression sleeve to allow the compression sleeve to flex as it compresses against the camber tube.17. The assembly according to claim 8 wherein the at least one axially displaceable member includes a pair of spaced compression plates and the at least one radially displaceable member is a gasket made of compressible material, the compression plates being adapted to squeeze the gasket to cause the gasket to expand radially, forcing an inner diameter of the gasket against an outer diameter of the camber tube, and locking the camber tube in place relative to the axle plate.18. The assembly according to claim 8 wherein the at least one axially displaceable member includes a locking collar and the at least one radially displaceable member includes a toothed locking sleeve, the toothed locking sleeve having a series of ramped teeth around a central bore therethrough that are adapted to engage fillets around a central bore in the locking collar so that the teeth are radially displaced to compress against the camber tube, locking the camber tube in place relative to the axle plate.19. The assembly according to claim 8 wherein the at least one axially displaceable member includes a threaded collar having internal threads and the at least one radially displaceable member includes a compression sleeve with external threads, the compression sleeve and the threaded collar being adapted to be disposed about a camber tube, threads on the compression sleeve and threads on the threaded collar being ramped so that, when the threaded collar is tightened onto the compression sleeve, the compression sleeve is radially displaced or forced against the camber tube, locking the camber tube in place.20. An assembly comprising, in combination:a pair of side frames including a left side frame and a right side frame; anda pair of wheel mount assemblies including a left wheel mount assembly attached to the left side frame and a right wheel mount assembly attached to the right side frame, the wheel mount assemblies supporting one or more camber tubes that are adapted to support left and right rear wheels, the wheel mount assemblies each comprising:an axle plate that is adapted to be attached to a wheelchair frame; anda clamp assembly adapted to be supported by the axle plate, the clamp assembly comprising:at least one axially displaceable member; andat least one radially displaceable member adjacent the axially displaceable member, displacement of the axially displaceable member causes the radially displaceable member to tighten against the camber tube to hold the camber tube in place relative to the axle plate.
