Description

Foldable helmet

The utility model is Motor-cyclist and occupant thereof, the helmet of wearing in winter for the safety of travelling.

The various helmets, particularly motorcycle helmet of Sheng Chaning all are all-in-one-piece in the market, can not fold, institute takes up space big, and is very heavy, goes out to carry very inconvenient, the summer and the collapsible helmet that spring and autumn, the sky was worn have recently appearred on the market, beautiful and comfortable when these helmets use, light generous when carrying, but the helmet that use winter remains all-in-one-piece, the structure dullness, very heavy.

The purpose of this utility model, the knights for motorcycle design a kind of helmet for the use in winter exactly, its structure uniqueness, elegant shaping, and can fold easily, carry very convenient.

Specifically, this collapsible winter helmet mainly comprises a preceding helmet shell, helmet shell after one, a lucite face shield, a chin shell, cushion before the expanded polystyrene (EPS), cushion behind folding cushion and the expanded polystyrene (EPS) in three expanded polystyrene (EPS)s, each above-mentioned parts, all be partly sphere shape, can guarantee so well to cooperate between them, pass through the mutual interlock of wedge mouth at its edge between the helmet shell of front and back, the front and back cushion is glued respectively on the helmet shell of front and back, folding cushion is between the cushion of front and back in three, between them and with preceding cushion between be connected with plastic sheeting, they are close to helmet shell inner face during expansion, when folding, can be earlier folding cushion in three be extracted out and collapse, again back helmet shell is pushed in the preceding helmet shell, chin shell and face shield fuse by rivet and front and back helmet shell in addition, face shield can be turned to preceding helmet shell top separately, also can be before the chin shell be turned to helmet shell top, the whole helmet has formed former helmet shell be center deployment with folding freely, beautiful design, carry and very easily, the companion that the motorcycle knights like.This effect that it brings is certain to obtain proof in product development in the future.

Below in conjunction with accompanying drawing, architectural feature of the present utility model is described by specific embodiment.

Fig. 1 is the front view of collapsible winter helmet,

Fig. 2 is the side view of collapsible winter helmet,

Fig. 3 is the front view of chin shell,

Fig. 4 is the right view of face shield,

Fig. 5 is the right view of chin shell,

Sequence number among the figure is represented respectively: brace 1, rivet 2, greatly mould pad 3, nut shaft 4, rubber blanket 5, for a short time mould pad 6, connecting plate 7, nut inserts 8, rivet 9, back helmet shell 10, back cushion 11, in folding cushion 12, preceding helmet shell 13, preceding cushion 14, face shield 15, chin shell 16, middle folded edge lining drag-line 17, comfort liner 18, ear lining 19, frenulum 20, bracelet 21, chin lining 22, hinge 23.

It is one symmetrical high 2.5 millimeters that the upper end of two sides of chin shell 16 respectively has, external diameter is 6 millimeters a boss, the center of boss is the through hole of 2.2 millimeters of ∮, it is one symmetrical high 2.1 millimeters that the lower end respectively has, external diameter is 12.5 millimeters a boss, the center of boss is 8 millimeters through holes of a ∮, the passage that five symmetries are respectively arranged about the center of chin shell 16, respectively there is symmetrical thick 2.4 a millimeters lonely shape nylon rach slot (it is glued in the corresponding face shield through hole) upper end of two sides of face shield 15, the wide of rach slot is 6.2 millimeters, 6 millimeters boss that can guarantee chin shell upper end like this are by also doing 35 ° swing, it is 12.7 millimeters through hole that respectively there is a symmetrical diameter lower end of face shield, and the diameter that can guarantee chin shell lower end like this is passing through of 12.5 millimeters boss; The chin shell is joined work by the lucite face shield in the boss about it and its outside, formed unified, but the combination that its mutual alignment can change again, like this when driving, if do not need face shield, face shield upwards can be dug, the outer surface of helmet shell before being attached to, since the through hole of upper end boss with mould pad 6 for a short time, connecting plate 7, spiral shell consumption inserts 8 usefulness screws fuse, and fuse by rivet 9 and front and back helmet shell, like this except the relative motion of face shield to the chin shell of last theory, can also be with face shield and chin shell as one, front and back helmet shell is done relative motion, be the cyclist think cooler, can be the axle center with rivet 9, with the upwards upset of chin shell, at this moment winter helmet has just become the helmet in spring and autumn, if not the time spent, cap takes off, two root system bands 20 in the pulling cap, folding cushion breaks away from housing (but connect with hinge 23 between the folding cushion in three, folding cushion also is connected with plastic hinge 23 with preceding cushion in maximum one in three expanded polystyrene (EPS)s.Therefore can not drop out the cap body), the inside of helmet shell is (because of 1/3rd of 14 helmet shell inner areas before front end accounts for of preceding cushion before the some of back helmet shell can being pushed, 2/3rds places of helmet shell before promptly back helmet shell 10 can push), the helmet shell is the center like this, partly shorten minimum volume into three, finish jackknife action.How the helmet shell fused before and after we saw again, before two sides of helmet shell 13 wide 7 millimeters, high 8 millimeters of a symmetry, bottom are respectively arranged is the through hole of half garden shape, it is 7 millimeters through hole that two sides of back helmet shell 10 respectively have the diameter of a symmetry, before and after the helmet shell with two rivets 9 it is fused, hole, the garden kink of back helmet shell 10 is on rivet 9, and the rivet that has inclined to one side head of the Pian Yuan hole of preceding helmet shell 13 and rivet 9 partly forms secure fit.The design is in order to reach every index of GB811-89 " motorcycle helmet " national standard, the helmet shell adopts certain thickness ABS engineering plastics injection molded, cushion adopts certain thickness expanded polystyrene (EPS), preceding cushion 14 gluings are at the inner surface of preceding helmet shell 13, be olive shape, back cushion 11 gluings are at the inner surface of back helmet shell 10, folding cushion 12 in three, when the helmet launches, the mutual extrusion of cushion before and after relying on, the inner surface of helmet shell before being attached to firmly, whole five block buffering layers form a sphere, folding cushion 12 in three, be dolioform, middle maximum, be square, just in time position, the crown when wearing, two limits lining is less, be isosceles trapezoid, they respectively link to each other with folding cushion in the maximum by two plastic hinges made from the folded plastic sheeting of folding 23, one side of the near ear position of two limits lining, a middle folded edge lining drag-line 17 is respectively arranged, when the helmet need collapse, as long as two middle folded edge lining drag-lines 17 about catching on forefinger, downward slightly Shi Xiaoli, in folding cushion just overcome before and after the extruding force of cushion, the inner surface of helmet shell before breaking away from, at this moment the inner surface of helmet shell before back helmet shell can unobstructedly push, till the cushion, the helmet space after folding undoubtedly greatly reduces, and carries very convenient before run in the forward position of back helmet shell, in addition in the middle of the folding cushion maximum one also have two plastic hinges to link to each other with preceding cushion, so during helmet shell inner surface, still do not break away from the helmet body before leave, the helmet is when row launches again, as long as back helmet shell is pulled out, folding cushion is taken advantage of a situation and is pushed away to helmet top one in inciting somebody to action again, face shield and chin shell is left behind again, and just forms a complete winter helmet.The comfort liner 18 of cushion outside in addition, ear lining 19, frenulum 20, the making and the structure of bracelet 21, chin lining 22 etc. are same as the prior art, repeat no more here.
