The present invention relates to an annular hook which is composed of a sealing ring and a hook, wherein the sealing ring is positioned at one side, the hook extends out of the opposite side, and the hook and the ring are integral. At least one elastic ring is connected with the annular hook by a penetrating knot. The number of the elastic rings and the number of rigidity rings can be alternately increased according to the requirement. The whole sealing ring system can be used for binding an article in a single line mode or in a crossed mode. Two edges of the elastic ring and two edges of the hook are straight in order to ensure that the load can be effectively transferred onto the elastic ring from the hook. A section of deformed part at the opposite side of the hook on the annular hook further ensures that the two edges are straight.

Description

Closed loop-hook and elastic band fastener

The present invention relates to the fixing thing and the strapping of article such as wrapping up, especially relate to a kind of by enclosed stiffening ring that has the closed loop elastic webbing and the tensile belt fastener of elasticity that hook is formed.

In order to wrap up or loose article stop up, need be wrapped in superscribing of different size and shape with cotton rope or expension belt.If the article of tying up be bulk or some size very big, perhaps its end position is fixing, then can't use a simple cyclic spring belt fastener that they are tied.Be easy to this fastener strapping goods loose, if bundle jail be difficult to untie, and in some situation, when when tying up, needing a hand to hold together article together, just can not fasten rope, unless also have people assistance in addition with two hands.

Some existing apparatus has the hook that links to each other with elastic threads, and it is generally used for article are fixed on bicycle, motor bike or other vehicle.This elastic threads is very thick, and itself is loose, and it is big to take up space, and is unsuitable for very nervous place, space.This apparatus is relatively expensive, makes complicatedly, and it will be tied many elasticas with fabric, and it is not held is wrapped on the hook.And this twines end might slippage when pulling force is big.

Other existing apparatuses have the more cheap hook that has ring, and these rings link to each other with elastic webbing or rope.But its hook is made by very weak single thick wire material or double joint heavy wire, and it might be drawn back under the effect of big pulling force.

US Patent 913962 has been introduced a kind of apparatus, it uses the closed ring elastic as expension belt, but their hooks with open loop or adaptor union and open loop type are connected, they can be drawn back under very big tension, and the wire rod that forms these rings all has and is exposed to outer end and tip, and they can tangle or scratch skin, clothes or tied article.

The present invention adopts the enclosed metal of rigidity or the ring that the highstrenghtpiston makes, at its terminal hooking, the closed loop elastic webbing is fixed on the ring that has hook with the knot that penetrates simple, anti-slip, form a tensile band, it can hook at an easy rate, and can prevent slippage, because all parts and knot all are closed ring.When the stretching band, its length can reach five times of its drift, and other ring, elastic webbing or common belt of affix just can be tied up various article again, comprising: loose article, as the clothing that will wash; Dish or screw-shaped article are as flexible pipe; The article that tie up are as tableware (tableware that the barbecue of for example picnicing is used); Sports equipment is as skis and bar; Support, as the binding plant in stake, or other article that will tie up.

Loop-hook is curved by wire rod, and it is shaped as the flat closed-loop that the hook end has two sweeps.Hook is made up of four parts, and the intensity of the loop-hook that the same wire rod of any usefulness of the intensity ratio of this hook is made is all high.Elastic is fixed on the position on hook opposite on the loop-hook with penetrating knot, therefore the both sides of elastic and the ring of loop-hook are positioned at same plane, and each limit of the hook on its each limit adjusting to a line loop-hook, has best usefulness and intensity aspect the belt will loading to pass to thus from hook, there is not the circular rings of rapid bending section not have weak or sharp keen node in addition, the position that does not also have the representative type easy fracture, thereby transfer charge most effectively.Side away from hook on loop-hook has slight, slick and sly bending section, has guaranteed that two limits of elastic can aim at two limits of hook, and has not weakened the intensity of loop-hook.A flat tensile band is provided thus, and it has the optimal support ability, and the space minimum that needs.

Because all adopted fully enclosed ring and had the hook of two sweeps endways, band can not tangle or scratch other article, and the hook that curves do not have the sharp distal end of giving prominence to, and these have guaranteed that all fastener is the shape of flats on its whole length.

Above-mentioned hook can curve simply with wire rod, perhaps the ring and hook make by wire rod or plastics, fasten common elastic again, just formed tensile flat band, this be a cheapness be solid system.

In use, power on the hook is that * is together tightly with annular hook, this thick hook is made up of four parts that the wire rod turning-in forms, can be with the wire rod end of this hook, be welded on the adjacent lateral wire, and mutual solder together, with the load limit of the counter-bending or resistance to deformation that improves hook, and can prevent the accidental separation of loop-hook and have a level and smooth end.
