Description

The neck buoy quoit

Affiliated technical field

What Fa of the present invention related to is a kind of buoyance in water buoy quoit that is worn over person neck.

Background technology

The buoyance in water buoy quoit that people see is that buoy quoit or the buoy quoit of foamed materials formula of inflatable all is the position of wearing the oxter chest that is enclosed within the people, such oxter buoy quoit is very practical, once saved countless people's life, people have had acceptance to the structure of such buoy quoit, and nobody makes structure to buoy quoit and the position of wearing has been changed again since the history.But we carefully observe and will find: the oxter buoy quoit is owing to being enclosed within chest, and the people is difficult to swim and advances like this; Large like this circle also causes the difficulty of carrying and depositing; Large like this circle also makes the people be difficult to have on it and gets out from little escaping exit; When saving at a distance the drowning people and since large like this circle air resistance ambassador people be difficult to its throw away farther, etc.It is relative that there is the listed shortcoming in front in the oxter buoy quoit, and we can not negate advantage and the historical contribution of its existence.

Summary of the invention

In order to overcome large, the bulky shortcoming of oxter buoy quoit resistance, I have invented a kind of buoy quoit of new form, its appearance is the same with the oxter buoy quoit, but it to wear the position that is enclosed within human body different, it is the neck that is worn over the people, its girth and volume are little much like this, because it is worn over people's neck as the neck, we are referred to as the neck buoy quoit.Can the neck buoy quoit be shouldered the important task of saving life? it is how to be applied to neck, what advantage does it have again?

The present invention's technical scheme of taking of dealing with problems is: buoy quoit is divided into inner ring and outer ring, the size of inner ring is that the neck that is worn over the people slightly has loose but can not be from people's head slippage, inner ring is a flexible type ring that the disconnecting mouth is arranged, the disconnecting mouth can carry out passive expansion and elastic recovery because of the elasticity of flexible type ring, the outer ring is the buoyant material circle, the buoyant material circle also has the disconnecting mouth correspondence position of a disconnecting mouth and flexible type ring, the flexible type ring attaches on the inner ring outside face foreskin film of buoyant material circle, the buoyant material circle just can be broken into two with one's hands from the disconnecting mouth by the user together with the flexible type ring and be expanded to the neck that can be set to the people and can flexibly reply again like this, and the people has on head that such buoyancy circle makes the people and can not swim like a tailor's goose and breathe air and can move flexibly swimming.

But the inner ring of neck buoy quoit of the present invention is becket or the plastic hoop of elastic dilatation and elastic recovery.The effect of becket provides the elastic force of expansion or the answer of whole buoy quoit, no matter becket all is the test of standing variety of way aspect consistency and elasticity, spring steel ring for example, this makes it be broken into two with one's hands very large extension mouth and can not wreck from the disconnecting mouth of ring by the user.But the density of becket is very large, can increase like this gravity of whole buoy quoit, in fact, though the becket among the present invention at inner ring thickness or highly all much smaller than outer ring buoyancy circle, this weight can not produce the large consequence that affects to the buoyancy of whole buoy quoit.Except using becket, also can the bear the responsibility important task of resilient ring of neck buoy quoit of the plastic material of some high-quality, some polyethylene plastics for example are although its consistency and elasticity is less than metal, but still equally can finish the function of repeatedly expanding and replying, and its weight is lighter.The size of inner ring resilient ring should be too not large or too little, too large can the slippage head, too little can have constriction to people's neck.

The outer ring of neck buoy quoit of the present invention is Polyurethane foam circle or inflatable rubber ring.Polyurethane foam has the little characteristics of the large weight of volume, and this makes its whole buoyancy important task of the present invention of bearing the responsibility.Polyurethane foam also has certain elasticity, this elasticity makes it be broken into two with one's hands very large extension mouth from the disconnecting mouth by the user and can reply again, can not be by the ability of slippage but this elastic force is still kept buoy quoit not at the neck that is worn over the people, the deficiency that it needs the elasticity of inner ring resilient ring to replenish this respect.Also can the bear the responsibility important task of buoyancy of inflatable rubber ring, but the buoyancy circle of inflatable has the danger of being scratched by reef, also will inflate before people use, and can not be fit to emergency situation like this.

Neck buoy quoit of the present invention has better advantage than oxter buoy quoit aspect a lot.For example, its circle week and volume, weight are all little much than oxter buoy quoit, and this just makes it be stored and carries provides convenience; When automobile is unexpectedly rushed in the water, people in the car can also with the hands advance various escape actions of opening car door or vehicle window smashing after putting on neck buoy quoit of the present invention, can also have on it and get out then from little vehicle window and climb up on top of the water, but be drowned too outward even if the oxter buoy quoit can not make the people escape from car like this; Because the neck buoy quoit is worn on the neck, the both hands that do not affect like this people carry out exercises, and the people can swim sooner and carries out various water surface work but the danger that also can not avale at the water surface; Because the circle of neck buoy quoit week and volume are little a lot, its aerial resistance is also little much like this, and people can arrive the drowning people to its throw farther, has lacked one section and the oxter buoy quoit is thrown than neck buoy quoit distance, be exactly this a bit of distance, but making falls into water can not get saving.

The invention has the beneficial effects as follows: the people puts on neck buoy quoit head of the present invention and can not sink under water, the people has on the neck buoy quoit and can also carry out various flexibly actions, can also get out from little escaping exit, the neck buoy quoit is easy to deposit and carry, and the neck buoy quoit moves simpler, quicker than the head of wearing of oxter buoy quoit, life jacket.

Description of drawings

Fig. 1 is the disk exterior view of neck buoy quoit of the present invention.

Fig. 2 is the middle sectional drawing in the horizontal side of neck buoy quoit of the present invention

Fig. 3 is the disk exterior view after the passive expansion of disconnecting mouth of neck buoy quoit of the present invention

Among the figure, 1 isocyanurate foam buoyancy circle, 2 resilient rings, 3 disconnecting mouths, 4 extension mouths, 5 foreskin films.

The specific embodiment

The present invention is carried out the explanation in a step below in conjunction with drawings and Examples.

If we produce a neck buoy quoit, the pattern of Fig. 1 is that its structure is held and levied so.Among Fig. 1, the inner ring of an isocyanurate foam buoyancy circle (1) attaches a resilient ring (2) and jointly consists of a buoyancy lifesaving circle on the neck that can just be worn over the people.No matter this holds other buoy quoit is that outer buoyancy circle or interior elastic ring have a disconnecting mouth (3), disconnecting mouth (3) correspondence of Internal and external cycle becomes common disconnecting mouth.This neck buoy quoit is less many than oxter buoy quoit, can it hold up human body at the water surface? we confirm that except putting into practice it is can be people's head holder the water surface, we also should carry out the explanation of science in specification sheets: originally, although oxter buoy quoit buoyancy is large, but it will hold up the above human body of people's chest on the water surface, although and neck buoy quoit buoyancy is relatively little, it only needs to hold up the head of human body on the water surface.

If we further understand its structure, the pattern of the Fig. 2 that so just occurs to the neck buoy quoit from middle cross section.We see that resilient ring (2) accounts for very little volume and thickness outside the inner ring of isocyanurate foam buoyancy circle (1) from Fig. 2, because what it was exercised is the function of elastic dilatation and elastic recovery rather than the function of buoyancy, its elasticity makes the people can just can break into two with one's hands at Emergency time once, and also having enough elasticity to keep after it is replied can be because of the effect slippage head of various unexpected power.We see that also the appearance of isocyanurate foam buoyancy circle (1) also wrapping one deck foreskin film (5) among Fig. 2, this layer foreskin film (5) can be cloth plasma membrane or polyethylene film, take off because polyurethane foamed material is easy to breakage, fritter is broken, this layer foreskin film (5) has prevented this phenomenon.The resilient ring of inner ring (2) only attaches securely upper at foreskin film (5) with glue rather than attaches on isocyanurate foam buoyancy circle (1), like this Internal and external cycle during all by elastic dilatation resilient ring (2) and the isocyanurate foam buoyancy circle (1) of inner ring can not pull because attaching mutually.

If we firmly break the neck buoy quoit of Fig. 1 into two with one's hands carry out disconnecting mouth (3) expansion from disconnecting mouth (3) by both hands, so just obtained the pattern of Fig. 3.Disconnecting mouth (3) among Fig. 3 has expanded into extension mouth (4), can have been worn on the neck that is set to the people like this, and people one looses one's grip, and whole buoy quoit can arrive the appearance of original Fig. 1 by elastical retraction again.If the people wants to take off neck and gives birth to the just the same both hands of circle and firmly break disconnecting mouth (3) into two with one's hands and become extension mouth (4).The cover of wearing of neck buoy quoit uses and only to need an action, and this moves very Simple fast, and from breaking to the time that only needs a second on the neck that puts into two with one's hands, this is to use any other buoy quoit, life jacket all can not accomplish such fast speed.Any all is wrong to the complicated design of escaping tool or the use formula design of many actions, and at the most dangerous crucial moment, all may determine to give birth to dead each second, moved because the person of meeting with misfortune may have no time also not have ability to finish many one again.
