The rotary contract type helmet is by the helmet shell systems, locking system, buffer system, ventilating system, rainproof bag, compositions such as winter protection pad.
The helmet shell is made of the middle helmet sheet 7 of helmet sheet 1, helmet sheet 2 and some, every helmet sheet is the surperficial shape of melon lobe skin, between each helmet sheet by the figure of the trapezoidal protruding voussoir 23(on its edge A-A) or the 22 mutual interlocks of hook-type arc groove be linked to be a whole helmet shell, the two ends of every helmet sheet have the hole, garden of a symmetry, penetrate a hollow attachment bolt 9 in the hole, garden, with 17 two packing rings of nut together with each helmet sheet kink, forming one is the rotatable compression in axle center, the complete rotary shell of the closure that can stretch, i.e. helmet shell systems with hollow attachment bolt.
The locking of rotary shell closure is chin strap 10 dual realizations by two pairs of mortise locks and one pair, the mechanism of mortise lock is that the cutting 14 on the helmet sheet 2 can be inserted in the jack of socket on the helmet sheet 1, transplant a cutting and just pinned by card 15, after pressing button 13, transplant a cutting just can unclamp and pull out, see figure D-D, one pair of being fixed on the helmet sheet 1 of one end is a chin strap, the other end has fastener, is that chin strap is locked on the helmet sheet 2 by fastener, like this mortise lock and be that chin strap makes helmet sheet 1,2 firm joining together, after double locking, closed rotary shell has very high global reliability, also is difficult for being dashed to draw after being impacted being scattered, and it is neck band 11 that an end is fixed on a pair of helmet sheet 1 inboard, the other end has fastener, it can be regulated length and be fit to different human needs, is after the fastener of neck band pins the neck neck, revolves the helmet that contracts and just takes without hand and put at the back porch back by system.The helmet sheet alignment pin 12 that spring is housed on the helmet sheet 2 inserts on certain helmet sheet behind certain locating hole 21, just be locked on the position of these helmet wearer's needs with helmet sheet 2 with at helmet sheet 2 to each centre helmet sheet between this helmet sheet, stir alignment pin, blocked helmet sheet just can rotate freely.Mortise lock is a chin strap, is necktie, and alignment pin has just constituted the locking system of the helmet.
Buffer system is by the buffering net, and side pad 3, helmet seat, interior head-shield constitute.The buffering net comprise annular through endless belt 4, latitude endless belt 5 and an end be fixed on the helmet sheet edge be guipure 6, through endless belt and be the guipure noose on the latitude endless belt, and can on the latitude endless belt, walk.When each helmet sheet rotation; be fixed on each helmet sheet be guipure and be guipure knot together through endless belt jointly on the latitude endless belt rotation synchronously slide; thereby form the buffering net of a closure on the surface of head; warp; the latitude endless belt is adjustable with the length that is guipure; can be fit to the size requirement of different people; make the helmet seat leave the left rotation and right rotation of takeing on the top and not influencing head slightly after the adjusting again; hair is to the resistance of buffering net when helmeting in order to reduce; can between the buffering net and the number of people, increase head-shield in one deck cloth matter; it link to each other with node through endless belt homology guipure and and the rotation synchronously of buffering net; rubber-like side pad by nut 17 anchorings on hollow bolt 9; it can cushion the impulsive force to the head side, can play elastic washer again, makes mutual turn between the helmet sheet tight and can pine; when the helmet shell is subjected to impacting; the part impulsive force is arranged by the helmet seat, promptly the lower edge of the broad of helmet sheet 1 and helmet sheet 2 is delivered on two shoulders; divide the impulsive force that has subtracted head, realized protection cervical vertebra.
Ventilating system is to utilize the helmet sheet window opening that has fan housing 8, and the ventilation hole 18 of regular on demand some of arranging, location hole 12, hollow bolt hole are realized the circulation of air in the helmet on each helmet sheet.And can not hinder the propagation of sound at the hollow bolt hole of ear position, do not influence the hearing of ear.The transparent visual fan housing 8 that can open is embedded in the helmet sheet, does not hinder the turn between the helmet sheet.Elastic hinge is adopted in fan housing and helmet sheet window opening upper edge, opens, closes automatic location, also can replace having the helmet sheet of fan housing with the helmet sheet that transparent material is manufactured.
Be made into rainproof bag with waterproof cloth and slide fastener, and have with the same window opening of fan housing size, raining the neck that can tie up to helmet sheet 1,2 when using just can be rainproof, and it can hold helmet bag or the article bag that revolves after contracting at ordinary times.Add winter and the equirotal foam-plastic blocks of each helmet chip size is embedded in the space between each helmet sheet and the buffering net, play the heat keeper effect, again can be as a cushion, heat keeper can contract and compressed simultaneously and diminish with revolving of helmet shell.
Except that the neck of helmet sheet 1,2, the helmet sheet of the rotary contract type helmet can be made into the helmet bar 19 further weight reductions of various section forms to satisfy the needs of some industry, connects with rope, band, bar, silk, face 20 between the helmet bar.Replace fan housing with a transparent windproof helmet sheet as middle helmet sheet, it is enclosed within outside the outer surface of helmet sheet 2, and can be locked in the place ahead of eyes, makes the usefulness of windproof mask, and figure three is embodiment part sectioned views of two kinds of helmet bars choosing arbitrarily.
Can change over inc with helmet sheet or helmet bar, the rotary contract type crash helmet of partial rotation housing uses for some tradesman, the method that changes form is: take off hollow attachment bolt 9, shed unwanted helmet sheet or helmet bar 1 successively, 2 and middle helmet sheet or helmet bar 7, an end that is chin strap 10, with the bolt that inserts air vent 18, be fixed on outermost helmet sheet of the helmet or the helmet bar, it is an end of necktie 11, with the bolt that inserts air vent 18, be fixed to helmet innermost layer the helmet sheet or the helmet bar on, it is on the position of suitable needs on the chin strap that the other end of bracelet spare anchors.So just change over the rotary contract type crash helmet of partial rotation housing.Put on the helmet,, be chin strap 10 and be that neck band 11 has double duty when being that helmet sheet or helmet bar had also just been locked simultaneously after chin strap 10 was fastened neck.
The anti-impact force of the helmet is required when not too high, and the rotary contract type helmet can be made following design and change: the first, deduct the neck part of helmet sheet 1,2.The second, in the middle of each helmet sheet or helmet bar, increase a hinge joint hinge 25, hinge can only rotate inwards and can not further revolve the volume that contracted to inner rotary.Carry, deposit more convenient (seeing figure five) through the helmet that changes like this.
The rotary contract type helmet militarily has bigger use value.The steel helmet that army now uses owing to being all-in-one-piece reason, has caused steel helmet can not be made into head, face, neck, all standing and totally enclosed protection form.Therefore, in modern war, this defective that used steel helmet exposes afield seems more and more serious.The object that make the sidepiece of many combatant's head of a quilts and bottom hits, the especially damage of the burn of flame and other radiation, and the rotary contract type helmet can address this problem preferably.When it is used for military service, the helmet is made following design changes: the first, the junction between each helmet sheet and the outer surface of hollow bolt 9 be the smooth surface transition be connected 24, body is slipped over smoothly.The second, the aperture of air vent diminishes, and the air vent quantity in helmet front diminishes, and reduces entering of flame.The 3rd, the exposed part of the helmet all is resistant to elevated temperatures.The 4th, fan housing or windproof helmet sheet are that bullet resistant material is made into.
