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 three-wheeled jogging stroller is movable between a deployed condition and a folded condition. Among other features, the stroller includes a forward member, a rear member, and a handle member that is rotatable to move the stroller from the deployed condition to the folded condition and back again. A locking side brace extends between the respective legs of the rear member and the forward member. Pulleys are attached to certain of the forward member, rear member and handle member. The stroller also includes first and second cables, and each cable is wr...

What is claimed is: 1. A three-wheeled jogging stroller movable between a deployed condition for transporting a child and a folded condition for compact storage of the stroller, the stroller comprising: a single front wheel and two rear wheels; a forward member having two spaced-apart legs and including a fork rotatably mounting the front wheel, a rear member having two spaced-apart legs, a lower end of each leg including two spaced-apart lower mounts for rotatably mounting the two rear wheels, a handle member extending upward and rearward from adjacent the upper end of the forward member, the handle member being rotatable to move the stroller from the deployed condition to the folded condition and back again, a flexible seat secured over at least one of the handle member and the forward member, an over-center, locking side brace extending between the respective legs of the rear member and the forward member and movable between a locked position for locking and stabilizing the stroller in the deployed condition and an unlocked position for allowing motion of the stroller from the deployed condition to the folded condition, first and second pulleys, each pulley being attached to one of the forward member, rear member and handle member, first and second cables, each cable being wrapped partially around and attached to at least one of the pulleys, the pulleys and cables arranged to cause motion toward the folded position of at least one of the forward and rear members upon rotation of the handle member in a first direction toward the folded position so that the stroller moves from the deployed condition to the folded condition by forward rotation of the handle member, the pulleys and cables further arranged to cause motion toward the deployed position of at least one of the forward and rear members upon rotation of the handle member in a second direction toward the deployed position so that the stroller moves from the folded condition to the deployed condition by rotation of the handle member, the brace including left and right rear elements connected to the rear member, and including a C-shaped element that is pivotally connected to the forward member so that a central section of the C-shaped element extends laterally between the legs of the forward member under the seat area. 2. The stroller of claim 1 further comprising a second lock pivotably secured to the handle member for locking the stroller in the deployed condition, the side brace and second lock both operable to lock the stroller in the deployed condition. 3. The stroller of claim 2 further comprising a post adjacent the handle member in the deployed condition, the second lock having an opening therein for receiving the post to lock the stroller. 4. The stroller of claim 2 wherein the brace is pivotable from the locked position to the unlocked position from both sides of the stroller. 5. The stroller of claim 4 wherein the brace is pivotable at connections between the rear element and the C-shaped element. 6. The stroller of claim 5 wherein forward movement of the handle member toward the folded condition causes the first cable to rotate the first pulley and thereby cause simultaneous rotational motion of the rear member toward the forward member. 7. The stroller of claim 6 wherein rearward movement of the handle member toward the deployed condition causes the second cable to rotate the first pulley and thereby cause simultaneous rotational motion of the rear member away from the forward member. 8. The stroller of claim 7 further comprising left and right side housings, each of which encloses a set of the first and second pulleys and cables. 9. The stroller of claim 8 wherein the two legs of the forward member are fixed to respective housings. 10. The stroller of claim 1 wherein an upper portion of the handle member is adjustable relative to a lower portion of the handle member. 11. The stroller of claim 1 wherein the rear member is U-shaped, and wherein each of the lower mounts for the rear wheels includes a bearing. 12. The stroller of claim 11 further comprising rear wheel hubs on each rear wheel, each hub including teeth interengageable with a pivotable brake mounted on the rear member so that the rear wheel can be locked. 13. The stroller of claim 12 wherein the rear wheels include axles removably received in the bearings of the rear member for more compact storage of the stroller. 14. The stroller of claim 1 wherein the first pulley has a diameter at least 2 times greater than a diameter of the second pulley. 15. A three-wheeled jogging stroller movable between a deployed condition for transporting a child and a folded condition for compact storage of the stroller, the stroller comprising: a single front wheel and two rear wheels; a seat made of flexible material, a frame mounting the wheels and seat, the frame including: a right side housing and a left side housing, a forward member having spaced-apart legs fixed to each of the housings at an upper end and rotatably mounting the front wheel at an opposite end, a rear member including first pulleys at right and left upper ends rotatably connected to respective housings and the rear member including spaced-apart lower mounts at right and left lower ends for rotatably mounting the two rear wheels, a handle member including second pulleys at right and left lower ends rotatably connected to respective housings, the handle member being rotatable about the housing to move the stroller from the deployed condition to the folded condition, first and second cables, each cable being wrapped partially around and attached to at least one of the pulleys, an over-center locking side brace extending between the rear member and the forward member and movable between a locked position for locking and strengthening the stroller in the deployed condition and an unlocked position for allowing motion of the stroller from the deployed condition to the folded condition, the brace including a rigid beam extending laterally between the legs of the forward member, the pulleys and cables arranged to cause motion of the rear member upon rotation of the handle member toward the folded position so that the stroller moves from the deployed condition to the folded condition by forward rotation of the handle member, the pulleys and cables further arranged to cause motion toward the deployed position of the rear member upon rotation of the handle member toward the deployed position so that the stroller moves from the folded condition to the deployed condition by rotation of the handle member. 16. The stroller of claim 15 wherein the housing is transparent. 17. The stroller of claim 15 wherein the locking side brace locks in an over-center position. 18. The stroller of claim 15 further comprising a second lock for locking the frame in the deployed condition. 19. The stroller of claim 1 wherein the C-shaped element includes arms extending rearward from the central section generally at 90째 angles, each arm being pivotally connected to one of the left and right rear elements to form hinges of the over-center, locking side brace.
