    • A generally square-shaped doll bed (10) includes a square base (11) supporting a quartet of vertical posts (13-16) at its corners. The base defines a center recess (12) within which a platform is supported by a pivoting arm (32). The pivoting arm is secured to a further pivoting arm (34) which extends outward beyond the base and terminates in a depressible pad (35). A doll (40) is supported above the platform by a pair of resilient bands (42-43) secured to frame members coupled between the vertical posts. As the user depresses and releases the pad, the platform (30) exerts upward forces against the doll causing it to move in a jumping action.
    • 大致正方形的玩偶床(10)包括在其角落处支撑垂直杆(13-16)的四重组的方形底座(11)。 基部限定了中心凹部(12),平台由枢转臂(32)支撑在该中心凹部内。 枢转臂固定到另一个枢转臂(34),该枢转臂向外延伸超过基座并终止于可压垫(35)中。 玩具(40)通过一对固定到联接在垂直柱之间的框架构件的弹性带(42-43)支撑在平台的上方。 当使用者按压和释放垫时,平台(30)向玩偶施加向上的力,导致其以跳跃动作移动。

    • A piston or plunger comprises a piston body (10) and a sealing member (17). The piston body (10) is preferably made from metal by moulding, such as casting or pressure moulding and sintering. The sealing member (17) is made from a thermoplast, such as polytetrafluoroethylene (PTFE). The piston body (10) has an outer or an inner peripheral surface part (14) in which axially extending depressions or grooves (15) are formed during moulding of the piston body. The axially extending grooves (15) may be open at one or at opposite ends. An annular sealing member blank (19) is applied to the peripheral surface part (14) and is deformed and forced into tight engagement with the peripheral surface part (14) and into the grooves or depressions (15) formed therein. The sealing member (17) formed is also exposed to a heat treatment. The piston or plunger having the sealing member (17) applied to an outer peripheral surface part (14) may, for example, be used in shock absorbers. Alternatively, the sealing member may be applied to an inner peripheral surface part. In such case the piston or plunger may be used as a stationary sealing device for encircling and sealingly guiding a reciprocating shaft or a piston rod.
    • 活塞或柱塞包括活塞体(10)和密封构件(17)。 活塞主体(10)优选通过模制(例如铸造或加压模制和烧结)由金属制成。 密封构件(17)由聚四氟乙烯(PTFE)等热塑性塑料制成。 活塞体(10)具有外部或内部周边表面部分(14),在活塞体的模制期间,其中形成有轴向延伸的凹部或凹槽(15)。 轴向延伸的凹槽(15)可以在一个或相对的两端敞开。 环状密封构件坯件(19)被施加到外周表面部分(14)并且变形并且被迫与周面部分(14)紧密接合并形成在其中形成的凹槽或凹部(15)中。 形成的密封构件(17)也暴露于热处理。 具有施加到外周面部分(14)上的密封构件(17)的活塞或柱塞可以例如用于减震器中。 或者,密封构件可以施加到内周面部。 在这种情况下,活塞或柱塞可以用作固定密封装置,用于环绕和密封地引导往复轴或活塞杆。
