    • An inflation valve for a recreational balloon includes a housing for fitting within the neck of a balloon and formed of resilient, highly stretchable material. A wall of the housing surrounds an internal compartment and a housing port extends from the compartment through the wall. A needle extends through the compartment and has a longitudinal air passage therein and a needle port extending from the air passage. The needle is movable within the compartment from a closed position in which the needle port is not aligned with the housing port to an open position in which the needle port is aligned with the housing port.

    • A wall walker toy car has a wheel with a sticky peripheral surface that normally extends partially out of a car body. The wheel is supported on a pivotable frame that responds to impact on a part, which would move relatively, to allow the frame to move up under the action of a spring cushion. A second position of the wheel is shown dotted where the wheel is fully retracted into the body so that the sticky surface is less exposed to dust and dirt and therefore has a longer serviceable life in practice.
    • 一个沃尔沃玩具车具有一个带有粘性外围表面的车轮,通常部分地从车身延伸出来。 轮支撑在可枢转的框架上,该框架响应于相对移动的部件的冲击,以允许框架在弹簧垫的作用下向上移动。 车轮的第二位置被示出为虚线,其中车轮完全缩回到车身中,使得粘性表面较少暴露于灰尘和污垢,因此在实践中具有更长的使用寿命。
