Definitions

  • the invention relates to a helmet, in particular a bicycle helmet made of plastic.
  • a helmet in particular a bicycle helmet made of plastic.
  • it is known to manufacture bicycle helmets either from deep-drawn plastic or from a foamed plastic.
  • the manufacturing costs are extremely high, which impairs the practical use of such bicycle helmets, which is very desirable and necessary for safety reasons.
  • the disadvantage of deep-drawn plastic bicycle helmets is that they are relatively heavy.
  • Bicycle helmets made of foamed plastic can only be foamed in certain colors. A complete disposal of the helmets according to the current state of the art is not always guaranteed.
  • the object of the invention is first of all to create a helmet, in particular made of plastic, which can be manufactured at significantly lower manufacturing costs than the previously known plastic helmets, but the resistance to the stresses e.g. should not be affected in the event of a fall.
  • the solution to this problem is first seen in a helmet made of plastic, which is double-walled.
  • the double-walled construction combines the advantage of great resistance and, above all, the damping effect of the trapped air against that when the helmet falls forces to be absorbed with the further advantage of its very low weight of this helmet.
  • the double wall being made of a blown plastic.
  • a blown plastic is elastic, but of a certain hardness and thus e.g. especially suitable for a bicycle helmet.
  • the blown plastic can have a relatively thin wall, which contributes significantly to the desired weight reduction.
  • the helmet according to the invention can easily be brought back into its original shape in the event of permanent deformation by heating the deformed area using hot water or using a hair dryer or the like.
  • the one-piece construction of the helmet according to claim 3 has the advantage that the complete helmet shell can be produced in a single production run, so that it is no longer necessary to carry out any assembly or adhesive steps. There is also no danger that glue points will come loose when the helmet is subjected to mechanical or thermal stress.
  • the multi-layer design of the helmet according to the invention has the advantage that the cavity can - if desired - be filled or designed with special insulating material, which can be important for certain purposes or for special insulating material itself that cannot be injected or foamed .
  • means which stiffen the walls of the helmet when subjected to pressure but also when the helmet is twisted relative to one another.
  • the double-walled design creates a helmet that fully meets the technical requirements with regard to strength and also far exceeds the properties of conventional helmets made of polystyrene (bicycle helmets).
  • the stiffening has the advantage that in the event of a user falling and impact with the head protected by the helmet on a hard object, pavement or the like, the helmet according to the invention can absorb a greater impact energy than a helmet which has no stiffening. In the latter, it can happen that even with a minor impact, the two helmet walls touch at the joint and the impact energy still present then acts on the driver's head without damping.
  • At least one opening is expediently provided as a means for stiffening, the walls of which are closed in themselves, ie bring about a connection between the outer and inner wall in the region of the opening.
  • the walls of the cutout stiffen the walls of the helmet relative to one another and consequently make them more suitable for shock absorption.
  • This configuration has the additional advantage that it offers the possibility of making the breakthroughs to manufacture or at least to prepare in a blowing process for a one-piece helmet.
  • the two walls can expediently be formed together in the area of the openings and then cut out, as a result of which the openings in question are created.
  • the openings have the additional advantage that they provide air circulation between the head of the user and the inside of the helmet.
  • the subject matter of claim 8 has manufacturing advantages on the one hand, and on the other hand it causes a certain damping behavior in the area of the openings due to the inclined walls.
  • ribs can also be expediently provided on the outer and / or inner wall.
  • the entire cavity can be under positive pressure to increase the shock absorption.
  • Claims 20-24 show further expedient configurations for increasing the shock absorption property of the helmet according to the invention.
  • the hardness and / or wall thickness of the plastic can be matched to the helmet dimensions and / or the desired impact resistance.
  • a central recess is provided on the front side of the helmet facing the user, whereby the edge effect of the front of the Helmet is lowered.
  • fan wheels can be provided in the area of the openings, thereby ensuring improved flushing of the openings.
  • the fan wheels can be driven by the head wind or even by a solar cell, which e.g. located on the outside of the outer wall of the helmet.
  • Claims 34-37 relate to further refinements of the invention using specially designed air outlet openings for influencing the damping behavior of the helmet.
  • the present invention relates to a helmet, in particular a motorcycle helmet, which is characterized in that it has a helmet according to one of claims 1 to 37 as a base body and this base body carries an additional helmet shell in a fixed bond on the outside.
  • Conventional polystyrene helmets are therefore being replaced by the new basic body made of plastic and double-wall construction.
  • the invention relates to a method for producing a helmet, in particular a bicycle helmet according to one or more of claims 1-38, which thereby is characterized in that the helmet is blown from a plastic tube within a mold so that the tube forms within a cavity of the mold into a double wall forming the helmet.
  • a corresponding helmet can be produced in a particularly simple manner, and at the same time all the advantages of the plastic to be used for this purpose can also be transferred to helmet manufacture.
  • the stiffeners in the form of wall areas can also be introduced into the helmet, which touch each other and are then cut out, thereby creating openings which serve on the one hand to reinforce and to ventilate the helmet.
  • the helmet here bicycle helmet 1 is - as Fig. 2 shows - double-walled, ie it consists of an outer wall 2 and one Inner wall 3, which define a closed cavity 4 on both sides. At their ends 5, the walls 2, 3 also merge the cavity 4 outwards into one another.
  • the walls 2, 3 with their end faces 5 are thus an integral part of the bicycle helmet 1, which is made of a suitable plastic, preferably polyethylene.
  • damping strips 6 made of foamed plastic or rubber and the usual chin straps 7 can be attached to the surface 3 'of the inner wall 3.
  • the two walls 2, 3 penetrating recesses can be provided, in the molded parts 40, which carry the chin straps 7, a secure connection by means of a clamp fit, tongue and groove connection or the like.
  • the cavity 4 can expediently be connected to the outside air through small air passage openings.
  • larger openings 8 ′ can also be provided in their diameter, which are closed with a pressure relief valve, preferably covered with a valve 9 attached to the outside.
  • the impact force results in pressure on the two wall parts 2, 3 in the direction of the cavity 4. This applies in particular to the outer wall 2. This compresses the volume of the cavity 4.
  • a certain braking of the passage of air can prove to be an advantage.
  • the blade 9 is attached to the cutting line 10 on the outside of the helmet 1.
  • Other arrangements in this regard were also possible.
  • Fig. 3 shows purely schematically the blowing of such a helmet with the help of a mold 11, which has a recess 12 corresponding to the outer dimensions of the helmet to be manufactured.
  • a tube 13 is inserted into this recess 12 or recess, which is inflated via the air line 14 and cured in the desired manner under heat.
  • fastening slots for the chin straps 7 can advantageously be incorporated into the blown plastic in this manufacturing process. They have a higher tear-out strength than bicycle helmets, which are made of foamed plastic (e.g. polystyrene) or deep-drawn.
  • foamed plastic e.g. polystyrene
  • Recyclable plastic such as e.g. Polyethylene, polypropylene, copolymer, polystyrene copolymer, acrylic butatiene styrene, ABS, polyamide or polycarbonate can be used.
  • the wall thickness, the elasticity and hardness of the plastic can be adjusted according to the desired requirements.
  • the cavity 4 between the two walls 2, 3 can be filled with a foamed plastic. This can be done either in the form of a foam or by filling small balls made of foamed plastic, for example.
  • Fig. 4 shows a further embodiment of the bicycle helmet according to the invention with openings 30, 31 arranged on the top, which increase the rigidity when the two walls 2, 3 are subjected to pressure and thereby considerably improve the ability to absorb impact energy from the bicycle helmet 1.
  • the individual openings 30, 31 have side walls 34, 35, which connect the outer wall 2 to the inner wall 3, so that the remaining cavity 4 remains closed.
  • a rib 33 extending from the front in an arc to the rear is provided on each side of the bicycle helmet 1, which additionally increases strength.
  • the breakthroughs are e.g. 30, 31 elongated and arranged in the longitudinal direction of the bicycle helmet 1. In addition to the stiffness-increasing effect, this ensures particularly good flushing of the user's head area of such a bicycle helmet 1. From Fig. 6 it is also clear that the individual breakthroughs e.g. 30, 31 are arranged offset from one another, whereby the stiffness profile of the bicycle helmet 1 is further improved.
  • laterally attached rib 33 is shown in FIG. 6 to further increase the stiffening.
  • a ribbing increases the stiffening, see the rib 34 in FIG. 5 of the inner wall 3.
  • the manufacture of the openings 30, 31 can also be explained with reference to FIG. 6.
  • the bicycle helmet 1 consists of two walls 2, 3, which - as already mentioned - are made from a hose in the blowing process. After blowing, however, the tube walls 2, 3 are pressed against one another via partial areas 22, 23, 24 by means of tool parts, so that they adhere to one another there. The regions 22, 23 and 24 which are glued to one another are then cut out along the dash-dotted lines 10.
  • edges surrounding these areas 22, 23 and 24 are formed by the two parts of the walls 2, 3 which are sealed together there. This creates openings 30, 31 or air passage openings through which the outside air can reach the top of the user's head.
  • the resulting wall sections 2 ', 3' stiffen the helmet, since these sections form an angle with the course of the otherwise “smooth" outer surfaces 8, 9 of the helmet and thus the approximately in the direction of arrows 38, 39 (cf. FIG. 7) on the helmet 1 in the event of a fall, it is largely able to absorb impact energy.
  • the aforementioned angle can be different.
  • FIG. 7 shows that each of these wall sections 2 ', 3' runs in the direction of the other wall 2, 3 towards or away from it. This results in a honeycomb structure, which, however, as shown in FIG. 6, does not extend over the entire area of the helmet 1, but only over the partial areas where the impact resistance explained must be given.
  • Fig. 8 shows in section approximately analogous to II-II in Fig. 6, the two walls 2, 3 in wave form, the waves being approximately rectified or in "synchronous" to each other. Again, the contours 16, 17 of the "smooth" outer surfaces of the helmet 1 are indicated.
  • FIG. 9 shows a corresponding section of the two walls 2, 3 likewise in wave form, but the waves of the walls 2, 3 are directed opposite to one another or are not arranged “synchronously”.
  • the contours are also indicated here with 16, 17.
  • the teaching of this embodiment of the invention is to allow the walls (see FIGS. 7-9) or at least one wall (see FIG. 10) of the helmet 1 to run back and forth to the other wall in order to achieve a corresponding stiffening of the helmet , does not have to exist over the entire helmet area. It is sufficient to provide this in those helmet areas that are at risk of impact in the event of a fall.
  • FIG. 10 shows that the outer wall 2 is not led back to the other wall 3 every now and then, but runs smoothly, so that only the preferred inner wall 3 is led away from it for stiffening to the outer wall 2 every now and then, such as this illustrates the sections 3 'of the inner wall 3 in Fig. 10.
  • the smoothness of the outer wall 2 gives the helmet 1 a particularly pleasing appearance in this exemplary embodiment, while the inner wall 3 provides the desired rigidity and absorption of the impact energy in the event of a fall.
  • the two walls 2, 3 are still at a distance A from one another, as a result of which the production in the blowing process is facilitated.
  • the walls 2, 3 merge into one another at the side edges or end faces 5, as shown in the example in FIG. 10.
  • an air outlet opening can be covered with a valve of an elastic flap 9, with which the flap 9 offers a certain resistance to the air emerging through the opening 8 '.
  • other valves could also be used. It goes without saying that the aforementioned air outlet options can also be provided in the other exemplary embodiments.
  • one or more pads 18 can be provided as impact protection inside the helmet, which pad consists of a viscoelastic foam.
  • a foam has a particularly shock-absorbing effect.
  • the particular advantage of this foam is that it is viscoplastic, ie it can adapt to the shape of the head according to the inner curvature of the helmet 1 and then maintains this adapted shape even 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 has to choose from several helmets, each with layers of different thickness, made from such an elastic foam.
  • the design of the helmet 1 according to FIGS. 12 and 13 is characterized in that the helmet parts forming the walls 2, 3 are made of plastic as separate shells and then joined together at their edges 19, preferably welded or glued, so that the cavity 4 located between them is in turn closed.
  • the shell-shaped plastic parts of the helmet which form the outer wall 2 and the inner wall 3 can consist of thermoformed or injection-molded plastic.
  • the walls 2, 3 are made by themselves and then joined together, e.g. as explained above.
  • 3 stiffeners are provided, which can be in one piece with at least one of the walls 2 or 3 (cf. FIG. 15).
  • these stiffeners according to Fig. 14 can be made by themselves and connected to one of the walls e.g. be glued. It is recommended that these stiffeners 26a are also made of plastic. In the example of FIG. 13, these stiffeners 6a and 6b form a honeycomb pattern with the helmet walls 2, 3.
  • stiffeners 26 and also the possible embodiments of stiffeners explained in the examples in FIGS. 14-16 are preferably provided on the entire helmet, but at least on the helmet area, which in the case of a Fall can be loaded with an impact energy, at least as indicated in Fig. 13 by the arrow C.
  • stiffeners 26a extend from one wall 2 or 3 towards the other wall 3 or 2. They can either run at an acute angle to the aforementioned walls (FIG. 13) or at right angles thereto (Figs. 14-16).
  • the cavity 4 located within these walls is sealed airtight. In the event of a fall as a result of the crash of the helmet, this results in additional air being compressed by compressed air inside these cavities and thus the absorption of corresponding impact energy.
  • an air overpressure either during manufacture or preferably via a valve within these cavities of the helmet.
  • greater elasticity is created by a corresponding amount of overpressure, the desired resistance to impact energy and, above all, to absorb this impact energy.
  • any excess pressure in the cavities can be less than with a plastic material that is somewhat more flexible.
  • the prerequisite here is that there are no air outlet openings or bores in the walls 2, 3.
  • the invention can also be implemented with air outlet openings.
  • air outlet openings 8 are preferably provided in one of the plastic helmet parts, the outer wall 2, which, when the two walls 2, 3 are pressed together, allow the air in the cavity 4 to escape due to an impact, but at the same time oppose a certain resistance to the air outlet.
  • This resistance can be increased further if, in the case of a corresponding air outlet opening 8 ′, the resistance of a flap 9 made of an elastic material lying thereon is additionally opposed and is bent outwards by the air outlet.
  • a valve can also be provided.
  • FIG. 15 shows an embodiment with webs 26a, which are integral with one of the helmet walls, here the outer wall 2.
  • FIG. 16 shows that webs 6a of wall 2 intermesh with webs 6b of wall 3 and form the stiffening. Distances A could also be provided here, if desired.
  • FIG. 17 shows the arrangement of a fan wheel 25 in the upper region of the opening 30, which is rotatably mounted in the side walls 34, 35 of the opening 30 via lateral shaft projections 26, 27. This ensures a suction effect of the warming air prevailing on the inside of the opening 30 during the journey.
  • the fan wheel can expediently also be driven by a corresponding drive unit (not shown), which is operated by a solar cell (also not shown).
  • the solar cell should be attached to the side of the helmet.
  • FIG. 18 shows a motorcycle helmet 50 which, instead of a conventional styrofoam base body, contains a base body 53 in the form of a helmet of the type mentioned above.
  • the base body 53 is expediently equipped with the corresponding stiffening features.
  • a helmet shell 51 in FIG. 18 is provided as an integral helmet on the outside of the base body 53 in a fixed connection to it.
  • the helmet shell consists of an impact and shockproof plastic e.g. a polycarbonate.
  • a swivel visor 52 is provided on the front of the helmet shell 51 in the usual way.
  • the two walls 2, 3 of such a helmet can consist of the same recyclable plastic such as polystyrene, ABS, polyamide or polycarbonate. After removing the damping strips (foam elements) 6 and the straps 7, such a bicycle helmet can be disposed of as a whole.
  • 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 provided with noctilucent, fluorescent dyes, color pigments.
  • the helmet emits light as soon as it has been exposed to light, so that the driver can be better recognized in the dark. It is also possible to add special odor substances to the plastic material for the helmet in order to ensure a special sales gag for children's bicycle helmets or the like.
  • the helmet is not only to be used as a bicycle helmet, but is also accessible to very different areas of application.
  • the wall thickness, elasticity and hardness of the plastic can be adjusted according to the desired requirements.
