Description

The swimming helmet

Affiliated technical field

A kind of physical culture safety and sanitation protection articles for use that are mainly used in learn swim and water recreation leisure.

Background technology

At present, Shang Weijian really is convenient to the safety and sanitation protection articles for use of beginner's learn swim.Now, the floating apparatus of common water wing, life vest and so on, its technical characterstic are that buoyant device is placed in below the neck, mainly rely on external buoyancy that human body head is held out the water surface enduringly.This apparatus that causes human body to be carried and hinder by the buoyancy thing all the time in water is unfavorable for the vivid perception of beginner and grasps water-based, makes the beginner ignore the existence of self buoyancy from the beginning easily and depends on these apparatus excessively.In case water wing is slipped out of the hand, will be nervous even frightened, may accident take place because of panic just.So many people are for bringing the water of extinction still forbidding to the people.Other has a kind of mirror of swimming underwater, and people's eyes, mouth and nose cup can be lived, and can seal respiration channel when the human body dive, guarantees that dive person is not choked by water, and to not constraint of limbs, helps the vivid perception of beginner and grasp water-based.But the people that it only is fit to possess certain swimming ability uses, and can not guarantee beginner's ventilation that emerges safely under perplexed inaction state.In a word, also there is not a kind of product can thoroughly remove the security risk of swimming beginner at present; There is not a kind of product can when the guarantee of paddling safely is provided for the beginner, allow its limbs obtain the vivid chance of experiencing water-based and grasping water-based again with born state.This causes a lot of people to fail to learn swimming so far.

Summary of the invention

Main purpose of the present utility model be for first learning swim and on the water the people of playing relaxing provide a kind of and can take into account simultaneously that safety is paddled and articles for use are protected in the physical culture of vivid perception water-based, to solve the deficiency that above-mentioned apparatus exists.

The utility model utilizes that the buoyancy of human body in water just in time can overcome gravitational natural conditions under the normal condition, the buoyancy of considering human body can change a lot under different mental state, physiological status and motion state and the actual conditions that cause human body both might float might to sink, the situation of beginner in water is divided into two states: it is safe condition that waterline (referring to that specially human body is exposed at the boundary line of airborne part and water wave) is lower than the nostril, and it is precarious position that waterline is higher than the nostril.Should any intervention not arranged to the beginner under the safe condition, the position that this moment, human body was soaked in water is many more, helpless more, nothing is climbed and stepped on fulcrum, helps beginner's perception water-based more; Precarious position is next must to provide safety assurance timely and effectively.

By experiment as can be known: similar with the draught line of hull, everyone also each has one " water line ".When human body under lax naturally state, this line can be maintained at lip between the nostril.Human body allows limbs all under water under lax naturally state in other words, and when the height in nostril during near the water surface, head just can not continue to have sunk.Because at this moment the buoyancy that produces of health displacement just in time overcomes human body gravity, only otherwise allow trick touch in water, human body will be floating and can be breathed.Under the state of human body in anxiety, this line in the nostril to (according to the difference of tensity, upper and lower move) between the forehead.Be the people under the state of anxiety, it is following that the water surface can be sunk in the nostril.It should be noted that: though under lax naturally state, the mankind own the talent that floats in the water together,, this " water line " is too near to the nostril, has stormy waves to rise and fall slightly, and water wave shutoff respiratory tract frequently causes the water of choking, and then cause being nervous, contraction of muscle is moved on the water line.Not natatory in addition people does not know water-based, does not form the custom of holding one's breath synchronously with the shutoff of water wave yet, in case run into the water of choking, will be panic, even hold the both hands emergency high.Like this, the both hands that the head that surfaces is often raised high are compressed in the water, cause drowned danger at last.

From above-mentioned experiment as can be seen: the first, human body has buoyancy, and " water line " can be remained on below the nose in lax naturally, and this is the objective condition that people can learn to swim.The second, not natatory people is in the water, and his nostril is a safe line of demarcation.When waterline is lower than the nostril, he just is in safe condition; When waterline is higher than the nostril, he just in danger.The 3rd, why drowned danger take place in people easily, is because the too close water surface in people's nostril, and anyone swims in the water, and because of the cause of motion and stormy waves, waterline is shutoff nostril continually all.Just for the people of meeting water, when waterline is higher than the nostril he can with agility hold one's breath and appropriate reactions such as action remove to adjust position, make respiratory apparatus exceed the water surface and in time take a breath.This general because of in them to the familiar of water-based and formed habit.So, want to allow the people learn swimming, just must in the process of learn swim, provide allow he the energy vivid perception water-based chance.This chance provides manyly more, and is abundant more, and the progress of device for exercising swim is just fast more.Yet the people who does not also possess for some swimming abilities, the situation of reality is, seek out once the chance of vivid perception water-based, just must face the risk of once not knowing consequence (such as, for the people who uses water wing, only when slipping out of the hand, water wing could obtain once the chance of vivid perception water-based).Obviously, such chance is who displeasedly actively obtains.Reason that a lot of people are not easy to learn to swim that Here it is.From the contradiction that the angle of technology is dissolved " chance " and " risk " and deposited, be to realize that devoid of risk is from the swim key of ability of learning swim and the universal common people on a large scale.Therefore, can be made into the helmet shape of profile sub-elliptical body to the buoyancy material and add parts such as respiration channel, visual windows (being installed in the dash glass on the helmet) and aqueous vapor sealing, constitute a kind of placing and not only do not hinder limbs free movable on the head at water, and the water and the lifesaving appliance of buoyancy is provided in good time of can preventing to choke.Purpose is, buoyant device is placed in human body head (more than the neck), and with all organs tight protect of this device with human body head.Like this, in the time of in human body head slips into water, the device that possesses certain buoyancy is upwards drawing human body head all the time, makes it be tending towards surfacing; When human body only relied on self buoyancy to make head be exposed at the water surface, buoyant device also was ejected the water surface and loses upwards draw to head, thereby human body can be in the floating state of nature often.Simultaneously design and installation has the respiration channel of water shutoff valve on buoyant device, whether touches the opportunity that the water shutoff valve is controlled the water conservation of whether implementing to choke with waterline, has not only avoided choke water but also guarantee its ventilation that can emerge safely of beginner.

The utility model solves the problems of the technologies described above the concrete technical scheme that is adopted: in a swimming helmet of mainly being made up of buoyancy head-shield and respiration channel, the respiration channel of being made up of respirator, airway, communicating pipe and the valve that blocks water was not choked by water when not only having guaranteed human body respiration but also was guaranteed not produce in the head-shield fog block vision; Buoyancy head-shield profile sub-elliptical body, bigger slightly than human body head, be that the skeleton that respiration channel depended on is installed, constituting waterproof barrier again separates human body head and water, it is one has only when the exposed parts more than the water line slips in the water, can upwards draw the buoyant device of head with suitable buoyancy, the ventilation that can emerge of the head that can protect the beginner, and, guarantee that it obtains the adequate condition of vivid perception water-based with this fear watercore reason of eliminating the beginner.

The beginner has worn the helmet, and the place that is higher than water line is adjusted in the position of the valve that will block water, standing in the phytal zone slowly squats down, make limbs all under water, when water line snap horizontal plane, human body will be floating, only otherwise arm is surfaced, head just can not continue to sink, and experiences the sensation of personal floatation in water immediately.Owing to experience the existence of body buoyancy, the beginner will set up the confidence of association's swimming at once, and is attempting activity in water.In case sink because of certain action causes head, the valve that blocks water that at first is installed in the respiration channel on the helmet can be met water and be closed, and makes water can not enter respiration channel, anti-the choking of realizing holding one's breath; Because the water surface at this moment is higher than " water line ", and the volume of health entry is bigger, the buoyancy that the health displacement produces has surpassed human body gravity then, and this buoyancy function can be offset the energy that health sinks rapidly, makes the floating position of health back to nature; The valve that then blocks water can be opened again automatically, guarantees human body and extraneous air exchange.Because the protection of the helmet to respiratory tract arranged, the beginner can be audaciously with head not in water; Again because " water line " can nature to the horizontal plane snap, the head that plunges into water can naturally emerge again under the acting in conjunction of the suitable traction of helmet buoyancy and body buoyancy.It is free movable that this makes that the beginner can decontrol four limbs carefreely, so can find out human body soon in hydrogymnastic main points, grasps the movement technique that keeps head even chest to surface, and then remove the swimming of helmet association.

In sum: when the buoyancy head-shield can correctly be placed in human body head to the swimming helmet that all organs of head are implemented tight protection in conjunction with what the respiration channel of the water that can prevent to choke was formed; just can make not natatory people freely movable in water; not only do not have the danger of choking water and sinking to suffocating; and can make the people be in the floating state of nature often, allow the beginner obtain the chance of vivid perception water-based at any time.

The above-mentioned helmet can be worn when first learning swim, it makes full use of the human body self condition, implement " ' safety ' and ' chance ' also deposits " and be the design philosophy of main points, make a kind of head-shield of sub-elliptical shape and itself and respiration channel are combined, constituting a kind of placing does not only hinder limbs free movable at water on the head, and the water and the lifesaving appliance of buoyancy is provided in good time of can preventing to choke is principal character of the present utility model.It can realize and only providing when causing the head dive because of external force or limb activity the suitable buoyancy that upwards draws head until the floating position of health back to nature and the function of water choking-proof.

Effect from using the utlity model has following advantage:

1, because the helmet is worn on the head firmly, there is not the situation of accidentally dropping and causing danger, improved the reliability of swimming safety greatly because of safety appliance.

2, because respiratory apparatus and the organs of vision are in protected state all the time, the danger of the water of not only having avoided choking has guaranteed the health of swimming, and can also make beginner's unlikely undue fragility and standing to lose when other people play with water.

3, beginner's limbs can be in the state that does not have external buoyancy, and the existence of vivid experience self buoyancy is known from experience the man day immediately and is born with and can floats over happy in the water, helps positive cognitive water environment.

4,,, reach the harmonious coexistence of people and water so the actual effect that the beginner can vivid experience exercises causes can be found out human body soon in hydrogymnastic main points because the limbs free movable condition under nature that allows is provided.

5, because the protection of head-shield, the people of playing relaxing not only whereby block sunlight can also allow not natatory people lie in sleep in the water and the interference that needn't worry to cover the face ripple to the acute irradiation of skin and eyes.

6, Jin Shi the swimmer swimming that can put on one's glasses can not affect one's power of vision because of water drenches eyeglass.

The specific embodiment

In the illustrated embodiment, main body---the head-shield of the swimming helmet, be divided into former and later two half ones by the opening of both sides, the opening part available water of head-shield first half (Fig. 3-12) and head-shield latter half of (Fig. 3-15), hermetic seal slide fastener (Fig. 3-14) fasten, and form the profile of a similar elliptical shape; Water, hermetic seal slide fastener (Fig. 3-14) are closed head-shield both-side openings, prevent the union piece of helmet the inside water inlet; Head-shield is except that dash glass (Fig. 1-4), but all the other just make the gas storage interlayer of sealing with soft plastic material voluminously; Dash glass (Fig. 1-4) is the transparent material that is embedded in the head-shield front, constitutes the visual windows of the helmet; Dash glass (Fig. 1-4) still is the brace foundation of respirator (Fig. 1-5) simultaneously; The appearance structure of respirator (Fig. 1-5) is seen Fig. 4; Respirator is fixed on the dash glass (Fig. 1-4) and head-shield housing of the helmet by respirator upper support (Fig. 1-1) and respirator lower support (Fig. 2-11); The structure of respirator upper support (Fig. 1-1) is seen Fig. 9, and wherein the shape of spring support 1 (Fig. 9-33) is seen Fig. 6; The structure of respirator lower support (Fig. 2-11) is seen Figure 10, wherein the shape of spring support 2 (Figure 10-40) is seen Fig. 7, its end is inserted in the spring support slot (Figure 10-37), and the other end is stuck in the extension spring hole (Fig. 5-21) of four-jaw reed (Figure 10-36); The appearance structure of four-jaw reed (Figure 10-36) is seen Fig. 5, and it is fixed on the four-jaw reed mount pad (Fig. 4-20) of respirator (Fig. 1-5) by four installation adjustment holes (Fig. 5-22) of four screws by self; The structure of respirator (Fig. 1-5) is seen Fig. 4, and its two airway interfaces (Fig. 4-17) are connected with an interior airway (Fig. 2-8,9) respectively, and airway is the plastic hose of hollow.Interior airway arranges that along the head-shield inwall leading to the top was communicated with communicating pipe (Fig. 2-6); Communicating pipe be one and be fixed on the head-shield top, with the hollow connector of break-through inside and outside the head-shield.The other end of communicating pipe (Fig. 2-6) the head-shield hull outside with two outside airway (Fig. 2-7,10) be connected, the other end of outer airway is connected with the outer airway interface (Fig. 8-23) of the valve that blocks water (Fig. 1-2) again.Respirator (Fig. 1-5) is by the respiration channel that connected and composed the helmet of pipeline with valve (Fig. 1-2) that block water.The structure of valve (Fig. 1-2) of blocking water is seen Fig. 8, and it pastes by the nylon of nylon buckles (Fig. 8-25) and head-shield both sides and buckles (Fig. 3-13) and be buckled together and adjust and the fixed position.

The valve (Fig. 1-2) that blocks water is to prevent to choke the security component of water, it by valve body (Fig. 8-30), water shutoff float (Fig. 8-28), float magnetic core seat (Fig. 8-29) and fixedly magnetic core seat four parts such as (Fig. 8-26) form.Wherein, water shutoff float (Fig. 8-28), float magnetic core seat (Fig. 8-29) and fixedly magnetic core seat three parts such as (Fig. 8-26) be installed in successively in the valve body (Fig. 8-30), a magnet is housed respectively in two magnetic core seats, and the magnetic pole installation direction of these two magnet is mutually exclusive.Unsteady magnetic core seat and water shutoff float can be done axially-movable in the valve body of hollow; Fixedly the magnetic core seat is fixed in the valve body with the form of screw thread and can does suitable axial adjustment; Should guarantee in the manufacturing water shutoff float and unsteady magnetic core seat buoyancy and less than their gravity and.When water does not flood the water shutoff float, water shutoff float and unsteady magnetic core seat gravity and in the place that the passage that just makes valve body (Fig. 8-27) is opened fully and the fixing repulsive force balance of magnetic core seat.When water logging during to the passage of valve body, the head of water shutoff float has been because buoyancy function has been pushed up the envelope gas boss (Fig. 8-24) of the valve that blocks water, the valve closing that blocks water, thereby stoped the respiratory tract water inlet.When blocking water valve in water during horizontal, the buoyancy of water shutoff float and unsteady magnetic core seat or gravity is by the inwall balance of valve body, and the repulsive force of two magnetic cores will promote to float magnetic core seat and water shutoff float withstands envelope gas boss, thereby can stop the respiratory tract water inlet.When the valve that blocks water is inverted in water since water shutoff float and unsteady magnetic core seat gravity and greater than their buoyancy with, the head of water shutoff float also can withstand the envelope gas boss of the valve that blocks water and close respiration channel under the effect of gravity.Therefore, the valve that blocks water is placed in any case in water and is all closed.

During actual the use, adjust the position (passage of valve body (Fig. 8-27) is higher than water line) of the valve that blocks water earlier, draw back water, hermetic seal slide fastener (Fig. 3-14), break the opening of helmet both sides into two with one's hands, slowly put in head in the helmet, use respirator (Fig. 1-5) that mouth and nose are covered air blowing then, check whether respiration channel is unimpeded.Then leave behind water, the hermetic seal slide fastener (Fig. 3-14) of helmet both sides are fixed on the helmet on the head.If at this moment feel too tightly or too pine of head-shield, can utilize volume-adjustment valve cock (Fig. 1-3) that it is adjusted to proper state.At this moment, the air-flow of breathing can only pass in and out through the passage (Fig. 8-27) of the valve that blocks water (Fig. 1-2) along interior airway (Fig. 2-8,9), communicating pipe (Fig. 2-6), outer airway (Fig. 2-7,10).After the beginner has worn the helmet, stand in the phytal zone and slowly squat down, make limbs all under water, when oneself " water line " snap horizontal plane, health will be floating.After the existence of having experienced body buoyancy, it is movable to attempt in water, in case sink because of certain action causes head, at first is installed in the valve that blocks water on the helmet and can meets water and close anti-the choking of realizing holding one's breath; Because the water surface at this moment is higher than " water line ", the buoyancy of health is greater than gravity then, and this buoyancy function can be offset the energy that health sinks rapidly, makes the floating position of health back to nature; The valve that then blocks water can be opened again automatically, guarantees human body and extraneous air exchange.Because the protection of the helmet to respiratory tract arranged, the beginner can be audaciously with head not in water; Because " water line " understands nature to the horizontal plane snap, the head that plunges into water can naturally emerge again under the suitable traction of helmet buoyancy again.It is free movable that this makes that the beginner can decontrol four limbs carefreely, so can find out human body soon in hydrogymnastic main points, in case grasped the movement technique that keeps head even chest to surface, just can remove helmet free practice.

In addition, when the people of playing relaxing put on the helmet in water surface sleep, the valve that blocks water need only be done the horizontal adjustment with regard to passable (shown in Figure 11-42).
