Detailed description of the invention

Referring now to accompanying drawing, Fig. 1 particularly illustrates a kind of helmet that is suitable for carrying out the shock resistance that the people the wore protection of traditional cricket.

Correspondingly, the helmet 1 has one by the impact resistance plastics material, is the polyester that glass fibre strengthens here, the crown inside 2 that punch die becomes.It also comprises shade 19 and the edge of being made of a lower inside 2 two parts.

Be provided with one crown outside 6, it is an arch, and is designed to roughly have an outside to hang down the edge, low edge, this outside and inner 2 edge 7 are consistent, and limit a cavity 8 between the two.

The shape of cavity 8 is in order to hold filler 9, and filler 9 is to be made of two thin slices that the pliable and tough plastic material that welds together along inside and

outside wall

10,11 is made, thereby limits the pouch 12 that a centre bore 13 therefrom passes.

The gel that freezes is housed in pouch 12, and this gel will freeze at zero degree or subzero usually, thereby will produce the effect of cooling after it is in a single day frozen in the process of melting.

Outside 6 is by embedding bolt 15 fix in position in inner 2 in the center, and passes to upper process that hole 16 fixes by nut 17.

Hole 18 is arranged in inner 2 with the form of disperseing, like this can so that cold air be passed in the space of inner 2 belows from the gel that freezes.

Edge 19 extends out forward by inner 2, and band 19a is fixed on the helmet on wearer's the head.

Less than specifying but owing to use traditionally, therefore also comprise in the present invention and being used for the fixing overhead device of the helmet, promptly be in one case one group from system on one side to the belt of another side, thereby pass from wearer's the crown, the lower surface of the helmet is promptly inner obviously above wearer's head, hair or skin.On the other hand, the dispersion piece of liner 21 is disposed on the edge of inner 2 inboard, and they are spaced from each other, and air is flow on the wearer's head surface.

In fact, this set provides a kind of facility very easily at this moment, wherein outside 6 with inner 2 bottom shelly or crown being consistent, just seem like this that ten minutes is as a common helmet shape.

Filler 9 can be removed and replace at any time easily, concrete grammar is: back out nut 17 earlier, then the outside is removed, replace original filler with another freezing filler again, the cooling effect of wearing the head part of this helmet like this can continue general about one hour or the time definite according to the test of being done.

Obviously, obviously than the single layer structure by same thickness and same plastic material made have better shock resistance protection effect by an outside and an inner double-walled layer structure of forming this comprising that the design provides.And by freezing in the device that gel sets structurally can white rami holds; the normal protection feature that can keep this helmet; for example helmet structure can be supported by the dispersion liner or the belt of routine, and does not need freezing liquid capsule directly to contact wearer's head or skin.

Other different users requires the participant to wear the cephalic protection part, and common like this potential problems are also all arranged when hot.Comprise cyclist, baseball player, hockey player and gridder etc. in the middle of these people.

According to each different situations of these different users, developed the special-purpose helmet.It will be appreciated by those skilled in the art that being diverted to design recited above in these different helmets each is a relative simple thing.

Referring now to accompanying drawing 3 and 4, the shown helmet is the type that a kind of builder who is adapted at working on the construction site wears, and often is known as the hardhead helmet.

The outermost shell of the helmet 20 is outsides 22 that are stamped to form by anti-ballistic materials, and it is the same with traditional building helmet material therefor, for example many carbonic acid plastic material.

The heat-insulating material 24 that also includes one deck arch, its link closely outer 26 of inner 28 so just can form cavity 30 between the two, that is to say, outside 22 and inside 28 all be arch, and inside 28 is overlapped externally in 22.

Cavity 30 is used for holding the filler 32 that freezes gel is housed, and it is to be made of two thin slices that the pliable and tough plastic material that welds together along

outer edge

34 and 36 is made, thereby limits pouch 38.

The gel that will freeze in zero degree or subzero is housed in the pouch 38 usually, so gel will produce the effect of cooling after in a single day frozen in the process of melting.

Heat-insulating material 24 and inner 28 combines, be embedded in the outermost housing via helmet belt 40 (representing) jointly by broken broken line, helmet belt 40 is the traditional forms in the building steel helmet, removably is connected on the shell by the clip 42 that is fixed on outside 22 in this case.

Shade 43 is a part of outside 22 in this case, is used for inner embedding or cover externally in 22 in this case.

The design of this helmet belt can mount and dismount its structure relatively easily,, goes to replace with another freezing pouch easily no longer ice-cold the time with convenient pouch 38.

Can see again that above-mentioned design makes coolant not have directly to contact with user's head or skin, and this design makes the air-flow control of the circulation of air, adiabatic function and refrigeration material top to be achieved.

Multiple other work post also needs the cephalic protection part.This wherein especially comprises fireman and welder.Under various situations, different cephalic protection parts has corresponding different development according to the accurate requirement of each work post.This area professional will be appreciated that it is relative simple thing that the design of above-mentioned cephalic protection part is migrated in the above-mentioned different helmet designs each.

Referring now to accompanying drawing 5 and 6, cap 50 mainly is to be made by the cloth the same with common baseball cap.This cap comprises cap hat 52 that is made of gusset 51 and the shade 53 that extends out from the cap hat.But what this cap was used is many sizes matching design, wherein the material of triangle cloth 51 is elastic fiber materials, allow the cap hat to extend and be fit to different head dimensions and cosily cooperate, do not have special also having of illustrating to knit the flexible liner 53a that material covers in the drawings by one deck cotton.This makes cap have more comfortable ductility.

At the inboard domes 54 that have the impact resistance plastics material to make of cap hat, it can meet the shape of the periphery 56 of inside 58 substantially, limits a cavity 60 like this and make inner 58 to be inserted in outside 54 between the two.These

parts

54 and 58 are to be secured on their position by the friction between the outer edge of extending cap hat material and each parts.

Cavity 60 is arranged to be used for hold therein filler 62, and it is to be made of two thin slices that the pliable and tough plastic material that welds together along

outer edge

64 and 66 is made, thereby limits folliculus 68.

The gel that freezes is housed in folliculus 68, and this gel will freeze at zero degree or subzero usually, therefore will produce the effect of cooling after it is in a single day frozen in the process of melting.

Housing

54 and 58 is fixed together as mentioned above and is fastened on the cap by screw 70 jointly then, and the cap that this screw 70 has this cap is labeled the button 76 that is had usually, is contained in the bottommost shell in the center.

The design can take out pouch 68, so that replace with another pouch that freezes.

The design is also applicable to wearing as the linksman, and the bump of protecting head to avoid golf has the effect of cooling simultaneously again.In this design, this makes flexible liner contact with wearer's head, makes cap hat self erecting on the actual top of head.In fact this means has the air gap equally, even the pouch of some other structure and dress gel is arranged, but still leaves certain the air gap between wearer's head and cap inside inner surface.

Under each embodiment situation, an inside and an outside all are provided, and under each situation, all form the hole that passes these parts, these holes are not specifically noted in the drawings, but can be provided with and judge according to size and position, so that need and realize carrying out balance between the cooling effect keeping adiabatic best by air duct.

Also has the cephalic protection part design of other style.What those skilled in the art will readily appreciate that is that it is relative simple thing that above-mentioned design and principle are diverted to every kind of other style.

These article described above are verified; they self are the people of purpose for wearing the cap or the helmet so that protection to be provided; no matter from user's comfortableness aspect; still from keeping and might improving security and convenience aspect; all be quite helpful, people that under the hot operation condition, work particularly.
