摘要： A pair of spaced-apart, parallel rings is provided, with each ring provided with a plurality of semicircular loop portions pivotally connected to the respective ring about its circumference. Each ring has two sets of a plurality of semicircular loops, a first outer set that is pivotal in a first direction away from the other ring, and a second inner set that is pivotally connected to the first set of loops of the other ring. The loops of each set are arranged in an overlapping manner, so that when one of the loops is rotated, all of the loops of that set are concurrently rotated. Since the inner sets of loops of the two rings are pivotally interconnected, rotation of any loop of either of the two second inner sets will concurrently rotate the other loops of the second inner sets. Rotation of these loops of the second inner sets is achieved by drawing closer the two rings or by pulling them apart. The two first outer sets of loops are free to rotate in either direction.
摘要翻译：提供一对间隔开的平行环，每个环设置有多个半圆环部分，其绕其圆周枢转地连接到相应的环。每个环具有两组多个半圆形环，第一外套，其在远离另一个环的第一方向上枢转，以及第二内套，其枢转地连接到另一环的第一组环。每组的环路以重叠的方式布置，使得当其中一个环路旋转时，该组的所有环路同时旋转。由于两个环的内部套环枢转地互连，所以两个第二内部组中的任一个的任何环的旋转将同时旋转第二内部组的其它环。通过拉近两个环或拉开它们来实现第二内套的这些环的旋转。两个第一外套环可以任意方向自由旋转。
