Definitions
- the invention relates to a helmet, in particular a bicycle helmet made of plastic.
- the bicycle helmets either from deep-drawn plastic or from to produce a foamed plastic.
- the manufacturing costs are extremely high, what the very desirable and necessary for security reasons Use of such bicycle helmets impaired in practice.
- the bike helmets thermoformed plastic the disadvantage that this is relative are heavy.
- Bicycle helmets made of foamed plastic can only be foamed in certain colors will. Also a complete disposal of the helmets according to the current state of the art is not always guaranteed.
- EP 0 517 091 A1 describes a two-part safety helmet with openings described, which consists of an assembled inner and outer shell and a has shock-absorbing insert.
- the proposed safety helmet exists thus consisting of three main components and is relatively complex.
- the breakthroughs are in each case on appropriately oriented tubular sections of the outer as well as inner helmet shell.
- the cross-sectional area of the openings decreases from the outside to the inside at a certain depth.
- a protective helmet presented in US Pat. No. 4,075,717 is also used for support a pressure-absorbing intermediate layer is used on the outer and inner helmet walls.
- the helmet presented has no openings and air outlet openings.
- US 4 124 904 describes a helmet with a valve element through which shock-absorbing spaces are filled with pressurized air can. This helmet also has no breakthroughs and air outlet openings.
- the object of the invention is in contrast first in a helmet, especially plastic create that with much lower manufacturing costs than the known plastic helmets can be manufactured, whereby but the resistance to the stresses e.g. should not be affected in the event of a fall.
- the task is carried out with regard to the helmet by the characteristic part of the Claim 1 solved.
- Advantageous embodiments are in the respective Subclaims realized.
- the task is performed by the The object of claim 14 solved.
- the present invention further relates to a helmet, especially motorcycle helmet, which is characterized is that he has a helmet according to one of claims 1 - 12 has as a base body and this base body on the outside an additional helmet shell in solid Verbund carries.
- Conventional helmets are made of styrofoam consequently through the new basic body made of plastic and double wall construction replaced.
- the invention relates to a method of manufacture a helmet, especially a bicycle helmet one or more of claims 1-13, which thereby is characterized in that the helmet is made within a shape a plastic hose is blown so that the hose itself within a cavity of the form to the helmet forming double wall.
- This can be a corresponding Helmet can be manufactured in a particularly simple manner, at the same time all the advantages of this the plastic used to make the helmet can be.
- stiffeners in the form of wall areas in the helmet can be brought in mutually touch and then cut out, causing Breakthroughs arise, on the one hand the stiffening and secondly, serve to ventilate the helmet.
- the helmet here bicycle helmet 1 is - as FIG. 2 shows - double-walled, i.e. it consists of an outer wall 2 and one Inner wall 3, which has a closed cavity 4 limit on both sides. At their foreheads 5 go Walls 2, 3 also close the cavity 4 outwards there into each other.
- the walls 2, 3 with their end faces 5 are therefore a one-piece bike helmet 1 forming part made of a suitable plastic, preferred Polyethylene.
- damping strips can 6 made of foamed plastic or rubber and the usual chin straps 7 may be attached.
- the cavity 4 can expediently contain the outside air be connected by small air passage openings 8.
- Complementary in addition to or instead of these openings 8 can also in their diameter larger openings 8 'may be provided closed with a pressure relief valve, preferably with a outside valve 9 are covered.
- the impact force puts pressure on the two wall parts 2, 3 towards the cavity 4. In particular this applies to the outer wall 2.
- the volume of the cavity 4 compressed.
- the air in the cavity 4 can penetrate through the openings 8, 8 'to the outside.
- the sheet 9 is on the section line 10 of the outside of the Helms 1 attached. Other arrangements would be also possible.
- Fig. 3 shows purely schematically the blowing of such Helmet with the help of a mold 11 which has a recess 12 according to the external dimensions of the one to be manufactured Helmet has.
- a hose 13 is inserted over the air line 14 inflated and heated in the desired Way is cured.
- the bicycle helmet in particular recyclable plastic such as Polyethylene, polypropylene, Copolymer, polystyrene copolymer, acrylic butatiene styrene, ABS, polyamide or polycarbonate can be used.
- recyclable plastic such as Polyethylene, polypropylene, Copolymer, polystyrene copolymer, acrylic butatiene styrene, ABS, polyamide or polycarbonate.
- the Wall thickness which are elasticity and hardness of the plastic adjustable according to the desired requirements.
- Fig. 1 also shows arranged at the top Breakthroughs 30, 31 which increase the rigidity Cause pressure on the two walls 2, 3 to each other and thereby the ability to absorb impact energy of the bicycle helmet 1 significantly improve.
- the individual openings 30, 31 have side walls 34, 35 which connect the outer wall 2 with the inner wall 3, so that the remaining cavity 4 is self-contained remains.
- the side walls run e.g. 34 over a portion of the distance from the outside to inner wall 2 or 3 towards each other and only in an inner one Area away from each other again.
- the bicycle helmet 1 To further stiffen the bicycle helmet 1 is one Rib 33 running from the front in an arc shape to the rear provided each side of the bicycle helmet 1, which in addition strengthening effect.
- the breakthroughs are e.g. 30, 31 elongated and in the longitudinal direction of the bicycle helmet 1 arranged. This adds to the rigidity a particularly good flushing effect the head area of the user of such a bicycle helmet 1 guaranteed. 4 further shows that that the individual breakthroughs e.g. 30, 31 against each other are staggered, creating the stiffness profile of the bicycle helmet 1 is still improved.
- Rib 33 is the one attached to the side in each case Rib 33 can be seen to further increase the stiffening.
- Ripping also increases stiffening, compare the rib 32 in FIG. 5, the inner wall 3.
- the bicycle helmet 1 consists of two walls 2, 3, which - as already mentioned - be made from a hose in a blowing process. Sub-areas 22, 23, 24 are after blowing, however the demolding by tool parts, the hose walls 2, 3 pressed together so that they stick together there. Then are dash-dotted along the drawn cutting lines 10 glued together Areas 22, 23 and 24 cut out.
- the aforementioned angle can, like the other exemplary embodiments show be different.
- FIG. 5 shows that each of these Wall sections 2 ', 3' towards the other wall 2, 3 runs away from it. This creates a honeycomb structure achieved, but as shown in Fig. 6, not extends over the entire area of the helmet 1, but only over the areas where the impact resistance explained must be given.
- Fig. 6 shows the stiffening of the helmet two walls 2, 3 in wave form, the waves being about rectified or in "synchronous" to each other. Again, the contours 16, 17 of the "smooth" outer surfaces of the helmet 1 indicated.
- Fig. 9 also shows the two to stiffen the helmet Walls 2, 3 in wave form, but with the waves of the walls 2, 3 directed opposite to one another or are not arranged "synchronously". Here too are the contours indicated with 16, 17.
- the walls (see Fig. 7-9) or at least one wall (see Fig. 10) of helmet 1 to the other wall and back again to allow a corresponding stiffening reaching the helmet does not have to cover the entire helmet area to be available. It suffices to do this on those helmet areas to be provided in the event of a fall at all are at risk of collision.
- FIG. 8 shows that the outer Wall 2 does not lead back to the other wall 3 every now and then is, but runs smoothly, so that only the preferred inner wall 3 for the purpose of stiffening to the outer wall 2 every now and then is led away from it like this the sections 3 'of the inner wall 3 in Fig. 8 clarify.
- the smoothness of the outer wall 2 gives in this embodiment the helmet 1 has a particularly pleasing appearance, while the inner wall 3 for the desired rigidity and absorption of impact energy in the event of a Fall worries.
- FIGS. 6-8 have the two walls 2, 3 still a distance A from each other, whereby the production in the blowing process is facilitated. It but it goes without saying that on the side edges or front ends 5 the walls 2, 3 as shown in the example of FIG Fig. 8 merge.
- Fig. 9 shows that as an impact protection inside the helmet or several pads 18 can be provided, which consists of a viscoelastic foam.
- a such foam has a particularly shock-absorbing effect.
- the special one The advantage of this foam is that it is tough and elastic is, i.e. according to the inner curvature of the helmet 1 Can adapt head shape and then this adapted shape maintains when the helmet is removed from the head. This is cheaper than an inner lining made of an elastic one Foam, since in the latter case the user several helmets, each with different thicknesses Layers of such an elastic foam Selection must offer.
- the invention can also have air outlet openings be realized. This can also, in addition to Absorption or damping of the impact energy through the breakthroughs 30, 31 air damping happen in the way that preferred in one of the plastic helmet parts outer wall 2 air outlet openings 8 are provided, which due to the compression of the two walls 2, 3 an impact, the air in the cavity 4 escape leave, but still a certain amount of air outlet Oppose resistance. This resistance can still be done be increased if there is an appropriate air outlet 8 'additionally the resistance of one on the outside opposed lying flap 9 made of an elastic material, which are bent outwards through the air outlet becomes. Alternatively, a valve can of course also be provided be.
- FIG. 10 shows the arrangement of a fan wheel 25 in the upper one Area of the opening 30, which has lateral wave approaches 26, 27 rotatable in the side walls 34, 35 of the Breakthrough 30 is stored. This will help you while driving a suction effect on the inside of the opening 30 prevailing, warming air guaranteed.
- the fan wheel can expediently also be provided by a corresponding motor unit (not shown) are driven by a likewise (not shown) solar cell is operated.
- the solar cell is conveniently attached to the side of the helmet.
- Fig. 11 shows a motorcycle helmet 50, which instead a standard polystyrene base body a base body 53 in the form of a helmet of the type mentioned above includes.
- the basic body 53 is expediently included the appropriate stiffening features.
- the helmet shell 51 On the outside of the base body 53 is in a firm bond to this a helmet shell 51 in FIG. 11 as an integral helmet intended.
- the helmet shell consists of an impact and Shockproof plastic e.g. a polycarbonate.
- Swing visor 52 At the The front of the helmet shell 51 is in the usual way Swing visor 52 is provided.
- Polyethylene is preferred as the material for producing the helmet. But it could also be used: polypropylene, copolymer, Polystyrene copolymer, acrylic butatiene styrene, ABS, Polyamide, polycarbonate and PET.
- the blown plastic material can be coated with noctilucent, fluorescent dyes, color pigments. This gives the helmet as soon as it is exposed to light was, lights off, so that the driver recognized better in the dark can be. It is also possible to use the plastic material for the helmet with special scents to thus a special sales gag for children's bicycle helmets or the like. To ensure.
- the helmet is not just a bicycle helmet is to be used, but very different areas of application is accessible.
- the wall thickness, elasticity and hardness of the plastic are adjustable according to the desired requirements.
