Abstract

The invention relate to an elastic pull rope device with a safety rope, comprising an elastic pull rope, a safety rope unit and two end point connecting members, wherein the elastic pull rope comprises two main end points which are oppositely arranged; the safety rope unit surrounds the outer surface of the elastic pull rope and comprises two auxiliary end points which are opposite and correspondto the main end points; and the end point connecting members are used for respectively connecting and fixing the main end points of the elastic pull rope and the auxiliary end points of the safety rope unit. Because the safety rope unit surrounds the outer surface of the elastic pull rope, the elastic pull rope device has the use safety, also beautifies the product appearance, and can be utilizedby matching with other sport equipment lightly, and the application of the elastic pull rope device is ensured.

Description

technical field [0001] The invention relates to a fitness device, in particular to an elastic drawstring device with a safety rope. Background technique [0002] refer to figure 1 Many fitness machines 1 that utilize an elastic drawstring 11 to achieve fitness effects are prone to oxidative embrittlement because the elastic drawstring 11 is made of materials such as latex and thermoplastic resin (TPR, thermoplastic resin). Especially when accommodating the fitness equipment 1, the elastic stay cord 11 is often bundled, so that the elastic stay cord 11 is more likely to be oxidized at the bend, and causes fracture when stretched. It causes great danger to the user, what's more, hitting the eye will cause blindness. [0003] The prior art puts a nylon weaving tube 12 on the outside of the elastic stay cord 11. When the elastic stay cord 11 breaks, the nylon weave tube 12 is not broken and the elastic stay cord 11 is limited in the nylon weave tube 12. At this time The elast...
