    • A trampoline with a frame has a rebounding mat that is tensioned to the frame with a plurality of flexible and cordlike linear elastic members. The rebounding mat is configured so that a non-tensioned portion thereof covers the elastic members to increase the trampolines useable area. In the more preferred embodiments, elastic members are cordlike flexible elastic members and the non-tensioned portion is segmented into overlapping petals to move freely with the tensioned portioned of the rebounding mat as it moves vertically. Preferably each cordlike elastic members is connected to the frame and the rebounding mat at one of two alternative positions to alter the tension. The alternative positions permit a tensioning process that extends the lifetime of elastic cords having a fabric sheath. This independent tension of each elastic member is via connector member that grips the rebounding mat but also grasps opposing the ends of the elastic members as well as central portion thereof so that two segment of the cord between each end and the central portion are preferably wrapped around the trampoline frame.
    • 具有框架的蹦床具有用多个柔性和绳状线性弹性构件张紧到框架的回弹垫。 回弹垫被构造成使得其非张紧部分覆盖弹性构件以增加蹦床可用面积。 在更优选的实施例中,弹性构件是绳状柔性弹性构件,并且非张紧部分被分段成重叠的花瓣,以随着其在垂直移动时与弹性垫的张紧部分自由移动。 优选地,每个绳状弹性构件在两个替代位置之一处连接到框架和弹回垫以改变张力。 替代位置允许延长具有织物护套的弹性帘线的寿命的张紧过程。 每个弹性构件的这种独立的张力是通过连接器构件,该连接器构件夹住回弹垫,而且还抓住弹性构件的端部以及其中心部分,使得每个端部和中心部分之间的帘线的两段优选地缠绕在 蹦床框架。
