Self-retracting extension limiting device |
| 摘要 |
A self-retracting extension limiting device. It is designed to be attached between a first object and a second object, where the distance between the first and second objects is variable. The device exerts a restoring force tending to draw the two objects together. A first, relatively weak restoring force is exerted over a range of distance. Then, when the objects have been separated to a defined limit of travel, the device exerts a much greater restoring force. The invention includes overlapping and self-contained elements so that unwanted slack is minimized. |

1. A self-retracting extension limiting device, comprising:
a. a first block; b. a second block; c. a first connective element lying between said first and second blocks; d. a second connective element lying between said first block and said first connective element; e. a first cable connecting said first block to said first connective element; f. a second cable connecting said second block to said second connective element; g. a first elastic tensile member connecting said first block to said second connective element; and h. a second elastic tensile member connecting said second block to said first connective element. |
