  • Publication number: 20040195868
    Abstract: An adjustable serving tray mainly includes an anchor apparatus located on armrests at two sides of a stroller. Each armrest has an inner side with a retaining flute formed thereon. The serving tray has coupling sections on two sides, each with an anchor trough and a latch lug. In normal usage conditions, the anchor trough engages with the anchor apparatus and the latch lug is latched in the retaining flute to anchor the serving tray. By releasing the anchor apparatus, the serving tray may be slid forwards to form a larger entrance space on the stroller to seat a child. Thus the child may be seated on the rear seat without removing the serving tray to improve convenience of use.

  • 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.
