Title:
引張された弾性コードを有するリバウンディング装置
Document Type and Number:
Japanese Patent JP2013504392
Kind Code:
A
Abstract:
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.
