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.

A tricycle-type wind-propelled toy land vehicle includes a sail with reliable tangle-free boom control. Both the disposition of the boom and the front wheel steering is actuated by a radio frequency remote control system. The vehicle further includes a skid plate surrounding the front wheel to prevent tip-over. The front wheel is steered by a worm gear drive which is self-locking. Boom control is provided by a guided cable system or, in an alternate embodiment, a direct gear drive to rotate the mast. In yet another embodiment, boom control is provided by...

What is claimed is: 1. A remote-controlled wind propelled land vehicle comprising: a frame having a rear portion including means for mounting two spaced apart coaxially aligned rear wheels; means at a front portion of said frame for mounting a single steerable front wheel, said rear wheels and said front wheel providing rolling support for said frame along a ground surface; a steering mechanism mounted to said frame for turning said front wheel about a substantially vertical axis; remote control means including a receiver responsive to remote control signals mounted upon the rear portion of said frame for driving said steering mechanism; a mast mounted to said frame for supporting an upright wind sail assembly including a swingably mounted boom connected to said mast and a sail; said remote control means further comprising at least one motor for steering said front wheel and further including means for manipulating said boom in response to control signals generated by a remote control sending unit; and said steering mechanism comprises a forwardly-extending rotatable drive shaft having a worm gear at a forward end thereof meshing with a planetary gear of said steering mechanism, said drive shaft having a rearward end connected to said remote control means. 2. The vehicle of claim 1 wherein said boom manipulating means comprises a guided cable which passes through a tubular guide along a substantial portion of its length, said cable attached to said boom at one end and attached to said remote control means at a second end thereof. 3. The vehicle of claim 2 wherein said tubular guide is affixed to said frame. 4. The vehicle of claim 3 wherein said tubular guide is a substantially circular cross-section. 5. The vehicle of claim 1 wherein said boom is swingably mounted to said mast and said mast is pivotably mounted to said frame. 6. The vehicle of claim 5 further including a partially restrictive rotatable joint between said boom and said mast, said joint including an arcuate slot in a collar which surrounds said mast and which is rigidly connected to said boom, said joint further including a pin rigidly affixed to said mast which projects laterally through said slot whereby said pin engages ends of said slot when said boom swings from one side to the other about said mast. 7. The vehicle of claim 6 wherein said means for manipulating said boom includes first gear means affixed to said mast, said first gear means being in meshing cooperation with second gear means connected to said remote control means. 8. The vehicle of claim 7 wherein said first gear means is connected to said mast along a bottom portion thereof. 9. The vehicle of claim 1 wherein said means for manipulating said boom comprises a DC electric motor. 10. The vehicle of claim 1 wherein said planetary gear lies substantially in a horizontal plane and includes teeth which surround the front wheel on all sides. 11. A remote-controlled wind propelled land vehicle comprising: a frame having a rear portion including means for mounting two spaced apart coaxially aligned rear wheels; means at a front portion of said frame for mounting a single steerable front wheel, said rear wheels and said front wheel providing rolling support for said frame along a ground surface; a steering mechanism mounted to said frame for turning said front wheel about a substantially vertical axis; remote control means including a receiver responsive to remote control signals mounted upon the rear portion of said frame for driving said steering mechanism; a mast mounted to said frame for supporting an upright wind sail assembly including a swingably mounted boom connected to said mast and a sail; said remote control means further comprising at least one motor for steering said front wheel and further including means for manipulating said boom in response to control signals generated by a remote control sending unit; and wherein said means for manipulating said boom comprises an extendable and retractable leaf spring. 12. The vehicle of claim 11 wherein said remote control means includes drive means between at least one motor and said leaf spring for extending and retracting said leaf spring forwardly and rearwardly beneath said boom. 13. The vehicle of claim 12 further including a coupling slidably connected to said boom at one end and rigidly connected to a distal end of said spring at the other end whereby retracting and extending said spring resiliently restricts lateral movement of said boom to a greater or lesser degree. 14. A remote-controlled wind propelled land vehicle comprising: a frame having a rear portion including means for mounting two spaced apart coaxially aligned rear wheels; means at a front portion of said frame for mounting a single steerable front wheel, said rear wheels and said front wheel providing rolling support for said frame along a ground surface; a steering mechanism mounted to said frame for turning said front wheel about a substantially vertical axis; remote control means including a receiver responsive to remote control signals mounted upon the rear portion of said frame for driving said steering mechanism; a mast mounted to said frame for supporting an upright wind sail assembly including a swingably mounted boom connected to said mast and a sail; said remote control means further comprising at least one motor for steering said front wheel and further including means for manipulating said boom in response to control signals generated by a remote control sending unit; and a skid plate affixed to said frame located proximate the front wheel, said skid plate including left side and right side surfaces which are ground engagable when said vehicle is traveling in a heeled over condition, each surface extending laterally beyond a line between said front wheel and each rear wheel.
