  • Publication number: 20030209882
    Abstract: A safety lock structure for strollers has a pedal mounted on the handle tube to couple with a latch strut located on a linkage plate. When the folding structure is released, the stroller frame is partly collapsed initially and the pedal and the latch strut form a latched condition to remind users that the frame is collapsible and must be stopped from completely folding to prevent hurting the child sitting on the stroller. When it is intended to collapse the frame, move the pedal downwards to release the latched condition of the latch strut and the pedal, then the frame may be folded and collapsed completely.

  • Publication number: 20030071441
    Abstract: A single-handed remote controller is disclosed. Such a controller is installed at the handle of an accordion frame and is connected to a lock mechanism of the frame through a flexible element. As the remote controller rotates relative to the handle, the flexible element is coiled around the handle, changing the relative position between the lock mechanism and the handle. The frame is thus changed to make the folding much easier.

  • Publication number: 20030052474
    Abstract: A leaning angle adjusting device is disclosed to adjust the leaning angle of the seat back on a stroller. The invention includes a flexible strap on the back of the seat back for providing support and a constraining element on the strap. The constraining element can arbitrarily adjust the support length of the strap so that the leaning angle of the seat back can vary within a desired range. The disclosed adjusting device is not only simple in operation but also provides a good positioning effect. The seat back is thus stably maintained at the leaning angle.

  • Patent number: 6478328
    Abstract: A locking device for collapsable stroller is located at the gripping portion of handle. The locking device comprises a housing, a pair of meshed gear members in the housing pivotal in two different opposite directions, a push button engaged with gear members, and a pair of steel cables coupled to the gear members. Whereby, pressing a push button pulls steel cables toward the center of gripping portion, thereby unlocking the latches so as to unfold the stroller thereafter. The stroller further comprises a safety mechanism at the upper side of one gear member. Safety mechanism comprises a pawl-like member caught by the gear member in the locked state of the stroller, thus preventing latches from accidentally being unlocked.

  • Patent number: 6442797
    Abstract: A flexible transmission device utilizes two flexible cables or ropes to pass through a narrow passage and connect two operating elements. An extendable mechanism is an intermediate of the two flexible elements. The extendable mechanism includes two tubes co-axially linked to each other. The two flexible elements overlap in the extendable mechanism in a free moving condition, which allows the relative distance between the two operating elements changing. When a flexible element is pulled from an operating member, a slider connected between the two flexible elements will be biased to fasten the two flexible elements so that the drag force can be transmitted to the second operating member.
