Description

Safety belt

The present invention relates to safety belt.Some embodiments of the present invention are in the field of safety harness (safety harness), special in the safety harness in the on use of lifesaving.Especially, although not exclusively, embodiments of the present invention relate to for the safety harness in the on use of lifesaving based on water in the situation that.

Background

Normally, lifeguard's safety harness comprises one or more buoyant members, and these one or more buoyant members are generally made up of the foamed material of buoyancy or are buoyant by filled making.These buoyant members are usually integrally formed in the vest (vest) or upper garment for the treatment of some types of being dressed by lifeguard.

Except the buoyancy of safety harness, conventionally also around outer setting webbing (webbing) structure of buoyant material, described webbing goes up to carry out multiple functions in place.In addition, periphery lifesaving appliance (reflective mirror, whistle etc.) can be attached to this webbing, means that they are present in easily on position always to use in high-strung situation.Webbing is also incorporated into structure buoyancy part conventionally, because usually engage different buoyancy parts by webbing, makes in some cases, rather than single upper garment/vest, describes that to have the tissue substance band that buoyancy part is attached to it will be more accurately.Significantly, aforementioned content description two safety harnesses extreme and lifeguard can be described as between more common.

The last function of being carried out regularly by webbing is to be provided for the anchor point of lifeline or safety lanyard.Normally, one end of guy rope will be attached to basic point (being hitched or be fixed to point on the coast etc. by rescuer) and relative end and be attached to the attached part releasedly of webbing, the releasable attached wearer that makes can discharge it with minimum effort, thereby wearer is left for to its buoying device, and be no longer attached to basic point.

US4,973,277(KHANAMIRIAN) " the safety belt harness system " of previously mentioned type disclosed, comprise relieving mechanism to allow the separation of safety line, it will be described below.Basic life vest comprises the vest design of front open type, and it is made up of multiple buoyancy plates (being foamed material in this case).Life vest is fixed on wearer by positive slide fastener, has the positive other thin fixing lining band (strap) of restriction vest in the situation that slide fastener lost efficacy.

Life vest is also provided with " safety belt harness system ".The safety belt of this safety belt harness system is passed in ring on life vest and is fixed to vest with the cam-type hasp discharging fast.Metal D circle is attached to the back side of vest movably.Safety harness is through D circle.The rope that serves as safety line can be attached to D circle.

The rope that is connected to the D circle of life vest is incited somebody to action tensioning for example enter water during attempting rescue time.If dress personnel's trouble of the life vest with D circle and need the rope being connected to from them immediately to separate, these personnel can untie the cam-type hasp of safe lining band so, owing to being connected to the tensioning of rope of D circle, the cam-type hasp of safe lining band will pull D circle away from it VELCRO(RTM on the back side of vest) formula connects.Because safety belt becomes and unties, the free end of band is by back-out D circle and will pull D to enclose away from vest, only leaves D and encloses the loose end that is attached to rope.D circle brings prevention from undesirable release of vest by be firmly fastened to safety by cam-type hasp.

Although for providing fast/urgent release to adopt cutting mechanism really to change between life vest, but the idea of all definite mechanism based on remaining on during operation the static line/safety lanyard under tensile force, unwarrantable situation in water at rapid flow in true life rescue situation, say nothing of in the time that water does not flow, and therefore the tensile force remaining in safety line is not offered help.

The recent experiment of the type life vest has represented some worrying problems from the release of safety lanyard about upper garment, particularly in the case of being never the place rescue victim of water of rapid flow.The reason of these problems is that in the water of static/stationary, to keep tensile force in safety lanyard to allow the enough freedoms of movement of rescuer be special challenge with the rescue function of fulfiling him simultaneously.Not tensioning of rope in these cases; This has stoped to discharge works effectively.Experiment has shown that crash rate exceedes 25% in the time attempting to discharge in slowly mobile or static water, be the life that can jeopardize the personnel that are not only absorbed in flood regime (or needing in addition water life-saving) significantly, also can jeopardize the situation of their life of rescuer own.

The life vest of multiple other prior aries is at US5,326,297(LOUGHLIN), US5,429,539(GLASA), US D260,162, US4,721,487(COCHRAN), US5,452,487(LEGGETT) and US5,230,645(CHENG) in differently describe.But, all suffer same shortcoming as discussed above in those.

Have been found that being not enough due to the tensile force in safety line/guy rope in reason static or that slowly the most release mobile water was lost efficacy and the obstruction of too much belt in relieving mechanism.Keep the conventional equipment of the tensile force in guy rope to prove length unsuccessful and guy rope in system and belt longer, problem associated with it is tended to become more and is worsened.

A target of the present invention is to provide a kind of safety harness equipment, and its low tensile force with reduction discharges failure risk and under high tensile force environment, correctly works simultaneously.

For purposes of clarity, term below should be rendered as the corresponding meaning with following general introduction:

" overall braces " should be rendered as the harness system that means arbitrary form with general safety band system.

Term " body region " Ying Qi reads in scope the most widely, and plate, lining band, buoying device that makes coat etc. should all be rendered as by the use of this term and be related to.

One embodiment of the present invention are shown in Figure 1.Safety harness according to the present invention comprises life vest 1.Although described the present invention with reference to life vest 1, should be familiar with, can imagine the embodiments of the present invention that do not comprise life vest.Life vest 1 comprises one or more buoyancy district 2, fixture 3 with hasp form, and this fixture 3 is for the fixing described buoyancy of the health around user (trunk) district 2.Life vest 1 can be formed as the shape of sleeveless T-shirt, as shown in Figure 1.Fixture 3 can selectively be slide fastener or similar form; If body region 2 is formed as making equipment to be pulled through user's head, so described fixture can be the form of frenulum (tie), tether (cord) etc., be enough to explanation, the form of described fixture is at least in part by defining/stipulate for the selected form in body region 2.

Safety harness also comprises the safety belt 4 according to one embodiment of the present invention, and this safety belt 4 illustrates in greater detail in Fig. 2 and Fig. 3.Safety belt 4 comprises the circle 10 of location dorsally, and the circle 10 that this is located is dorsally for being attached to guy rope by safety belt.Safety belt can by safety belt towards interior lip-deep for being attached to the Velcro(RTM of a pair of complementation of the corresponding pad on life vest 1) pad (not shown) is attached to life vest 1 releasedly.Safety belt 4 is attached to life vest 1 to stop with 4 in use around undesirable movement of life vest, but fastener should in the time that user expects, that is, require as long as minimum power is come from life vest 1 separating belt 4 in the time that safety belt 4 is discharged by user.

Safety belt 4 comprises relieving mechanism, and this relieving mechanism comprises quick release buckle 5, and this quick release buckle 5 can activate by user.Hasp 5 makes safety belt 4 fastening and can activate by unfasten one's seat-belt 4 first end and the second end, user to be discharged from safety belt 4 on open position by user around user on restraint location.Discharge hasp 5 and can have toggle (toggle), it is for being firmly grasped to cause that hasp 5 moves to open position from restraint location by user, thus first end and the second end of release safety belt 4.If safety belt 4 has the enough tensile forces that apply by guy rope, in the time snapping on open position, be with 4 easily from pulling around user.But as will be explained, embodiments of the present invention are useful in low tensile force environment, wherein relatively low tensile force applies by guy rope.

Safety belt 4 comprises Part I 6 and Part II 7, described Part I 6 is preferably connected by fixed agraffe 9 at first end place with Part II 7, although it should be understood that Part I 6 can for example sentence and be connected by other modes of sewing up at this first end with Part II 7.Fixed agraffe 9 is hasps of 8 profiles, and the end of Part I 6 and Part II 7 can be through this fixed agraffe 9 with securely but be bonded together adjustably.Part I 6 can be connected by quick release buckle 5 at the second end place with Part II 7.Part I 6 can be fixedly attached to described release hasp 5 by the second fixed agraffe 11, but, again should be familiar with, Part I 6 can for example be connected to quick release buckle 5 by other modes of sewing up.Fixed agraffe 11 is attached to the loose end of Part I 6 at intermediate point place itself to form the annular end district of the Part I 6 that keeps quick release buckle 5.Described Part II 7 is attached to described release hasp 5 releasedly by the relieving mechanism of hasp, for example, pass through the promptly camming of the quick release buckle 5 of Part II, for example, pass through inner teeth.

The use of two parts safety belt 4 allows the length of enclosing of wearer adjustment band, as shown in Figure 3, the only a bit of of described Part II 7 of simultaneously guaranteeing described safety belt must be through described relieving mechanism 5, thereby is reduced in the risk that this some the possibility of blocking occurs and is therefore reduced in while activation thrashing as a whole.The length of enclosing with 4 can be in fixed agraffe 9 places adjustment, as shown.

The described Part I 6 of described safety belt 4 also comprises elasticity extensible zones 8 so that pre-tensioner described safety belt 4.This elasticity extensible zones 8 can be formed by elastomeric material, for example elastic fabric, or can comprise spring mechanism or analog.Should be familiar with, the absolute form of described elasticity extensible zones can be selected suitably for the application with 4.Elasticity extensible zones 8 approaches quick release buckle 5 and applies tensile force to have the effect of this part of tension band 4, and no matter the degree of tensioning in 4 generally, that is, and the tensioning of introducing by guy rope.Advantageously, reduce or substantially avoided the inefficacy of the relieving mechanism of discussing with reference to the life vest of prior art.

Elasticity extensible zones 8 can be partly restrained, makes the at utmost limited of feasible extension, is not the elastic characteristic own by elasticity extensible zones 8, but by other extension control device control.Described extension control device can be by being attached together formation with non-elastic material by two points of safety belt 4, make elastomeric material is than the short length of distance between the described attachment point on described safety belt 4 under its relaxed state, and the maximum elongation of described elastomeric material is greater than described distance, make under zero tensile force, the effective length in the relevant district of safety belt is determined by the relaxed length of described elastomeric material, and under maximum tension power, the effective length in relevant district is the physical length in the described district of safety belt, the length that its maximum that is less than described elastomeric material is extended.

For operated release mechanism 5, the wearer of safety belt activates quick release buckle 5; Therefore the end of the described Part II 7 of described safety belt 4 separates from described quick release buckle 5.So the current elasticity extensible zones 8 under tensioning of the described Part I 6 of described safety belt 4 is retracted into, it is shorter, the length of not tensioning, pulls the described end separating of described quick release buckle 5 from the described Part II of described safety belt 4.Therefore, then by the movement of wearer be attached at safety harness in its guy rope potential/combination of intrinsic tensile force pulls described safety belt 4 to separate from described safety harness.When the flow rate of the water around user is while making can not guarantee from the tensile force of lifeline/safety lanyard that is attached to braces, embodiments of the present invention can be advantageous particularly.

Should note, although the description below a large amount of is based on around buoyancy, lifesaving safety harness, but the same technical development to this braces is applied more widely, there is potential application being different from knapsack manufacture, mountaineering equipment, parachute jumping braces and many more fields.Therefore the description of this paper should not be rendered as scope of the present invention is only limited to the safety harness of the on use of lifesaving on the water.
