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.

There is provided a mounting assembly including a frame portion of the walker apparatus having a first bore and a second bore extending in a direction generally perpendicular to the first bore. The mounting assembly includes a shaft assembly rotatably connected to a wheel fork. The shaft assembly also is partially disposed within the first bore. The shaft assembly has a recess configured to align with the second bore. The mounting assembly includes a securing member threadably engageable with and at least partially disposed within the second bore. The securing member couples to the frame portion of the walker apparatus. The securing member has a tapered end that engages with portions of the shaft assembly surrounding the recess and is a set screw according to one aspect. The shaft assembly is a bolt according another aspect.

1. A mounting assembly for fixedly mounting a pivotable wheel fork to a walker apparatus, the assembly comprising: a frame portion of the walker apparatus, one of the wheel fork and the frame portion of the walker apparatus having both a first bore and a second bore, the second bore extending in a direction generally perpendicular to the first bore;a shaft assembly rotatably connected to the other of the wheel fork and the frame portion of the walker apparatus and also being partially disposed within the first bore, the shaft assembly having a recess configured to align with the second bore; anda set screw threadably engageable with and at least partially disposed within the second bore, the set screw coupling to said one of the wheel fork and the frame portion of the walker apparatus and having a tapered end that engages with portions of the shaft assembly surrounding said recess, the shaft assembly being fixedly mounted to said one of the wheel fork and the frame portion of the walker apparatus thereby. 2. The mounting assembly as claimed in claim 1 wherein the recess is annular. 3. A walker apparatus having the mounting assembly as claimed in claim 1. 4. A mounting assembly for fixedly mounting a pivotable wheel fork to a walker apparatus, the assembly comprising: a frame portion of the walker apparatus, one of the wheel fork and the frame portion of the walker apparatus having both a first bore and a second bore, the second bore extending in a direction generally perpendicular to the first bore;a bolt rotatably connected to the other of the wheel fork and the frame portion of the walker apparatus and also being partially disposed within the first bore, the bolt having a recess configured to align with the second bore; anda securing member at least partially disposed within the second bore, the securing member coupling to said one of the wheel fork and the frame portion of the walker apparatus and engaging with portions of the bolt surrounding said recess, the bolt being fixedly mounted to said one of the wheel fork and the frame portion of the walker apparatus thereby. 5. The mounting assembly as claimed in claim 4 wherein the frame portion is said one of the wheel fork and the frame portion of the walker apparatus, the frame portion having an open first end facing the wheel fork, a closed second end opposite the first end, the first bore extending from the open first end towards the closed second end, and the frame portion having an exterior disposed between the open first end and the closed second end, the second bore being disposed between the open first end and the closed second end, the second bore extending from the exterior of the frame portion to the first bore. 6. The mounting assembly as claimed in claim 4, wherein the recess is annular. 7. The mounting assembly as claimed in claim 4 further including a bearing having an outer race coupled to the wheel fork and an inner race that abuts the bolt. 8. The mounting assembly as claimed in claim 7, wherein the frame portion is said one of the wheel fork and the frame portion of the walker apparatus, wherein the bolt is threadably engageable with the first bore, and wherein the bolt has a head positioned to operatively abut the inner race of the bearing. 9. The mounting assembly as claimed in claim 4 wherein the frame portion is said one of the wheel fork and the frame portion of the walker apparatus and wherein the securing member is a split tube press fitted to portions of the frame portion surrounding the second bore so as to engage with the recess of the bolt, the bolt being fixedly mounted to the frame portion thereby. 10. A walker apparatus having the mounting assembly as claimed in claim 4. 11. A mounting assembly for mounting a wheel fork to a frame portion of a walker apparatus, the wheel fork having a bore, and the assembly comprising: a shaft assembly coupled to the frame portion and at least partially disposed within the bore of the wheel fork; andan alignment member at least partially disposed within the bore of the wheel fork, the alignment member having a first portion shaped to extend around the shaft assembly and a resilient second portion configured to abut against portions of the wheel fork surrounding the bore, the alignment member thereby rotatably aligning and supporting pivoting of the wheel fork about the shaft. 12. The mounting assembly as claimed in claim 11, further including a resilient member disposed within the bore of the wheel fork and disposed adjacent to the second portion of the alignment member, the resilient member being configured to bias the second portion of the alignment member against the wheel fork. 13. The mounting assembly as claimed in claim 12 wherein the resilient member is an annular wire spring. 14. The mounting assembly as claimed in claim 12 wherein the alignment member includes a radially outwardly-extending top that couples the first portion and the second portion of the alignment member together. 15. The mounting assembly as claimed in claim in claim 14, wherein the alignment member includes a peripheral, rim portion that radially extends outwards and downwards from the top thereof, the rim portion being configured to fit over top of and abut with a top end of the wheel fork. 16. The mounting assembly as claimed in claim 12 wherein the apparatus further includes a spring lock ring configured to extend around and abut with the first portion of the alignment member, the spring lock ring biasing the resilient member towards the top of the alignment member. 17. The mounting assembly as claimed in claim 11 wherein the second portion of the alignment member includes a plurality of spaced-apart resilient projections. 18. The mounting assembly as claimed in claim 11 further including a bearing that rotatably connects the shaft assembly to the wheel fork. 19. The mounting assembly as claimed in claim 18 wherein the alignment member abuts the bearing. 20. A walker apparatus having the mounting assembly as claimed in claim 11.
