Abstract
A protective helmet having an inner hood includes a spacer knitted fabric of a monofilament yarn. The hood is covered by a pneumatic central layer which can be pressurized by means of compressed air and can be inflated by means of an air pump which can be, for example, removed and provided with valves. An outer layer consists of an inner textile layer which lies over the pneumatic central layer, and plates which are fixed to the textile layer, for example by adhesion. The plates include, for example, of plastic, composite materials, or natural materials. The plates can be arranged in such a way that joints are created thereinbetween, the outer layer thus being provided with a certain elasticity in order to cater for different head shapes and sizes.
Description
- 1. Technical Field
- The present invention relates to a flexible protective helmet.
- 2. History of Related Art
- Several flexible protective helmets are familiar.
- Their invention concept in general comprises creating a protective helmet that when not in use can be folded to save space and on the other hand, due to its shape and size, when in use is identifiable as a protective helmet. This as such should increase its acceptance.
- Several such protective helmets that can be folded have become familiar, for instance, from WO 00/57739 (D1), WO 01/24651 (D2), EP 0 802 741 (D3) and
EP 1 332 688 (D4). - Among the protective helmets mentioned here, the one for cyclists, disclosed under D1, is designed in modular concept and is thus foldable and can be dismantled, however, it is clearly identifiable as a protective helmet when in use. Space saving in a folded state is rather insignificant.
- The protective helmet according to D2 consists of an inner layer made of shockproof material that is disintegrated into truncated butt-joined or interlocked teethed pieces. This layer of shockproof material is covered with a textile and elastic material on the outside and inside. Due to this, when worn it feels more of a cap. The possibility of folding it is restricted due to the shape of the shockproof inner layer.
- The protective helmet that is familiar according to D3 features a cap-shaped design, whereby this cap is made of numerous, preferably six, spherical segment-shaped pieces, which are preferably made of foamed plastic. Among themselves, for instance, these segments are connected by means of ribbons.
- The protective helmet according to D4 is again made in modular concept and based on the desired intensity or type of head protection it can be complemented in modular manner.
- Whereas the ones according to D1 and D4 only partially fulfil the tasks, the ones mentioned in D2 and D3 are more relevant to the present invention without fulfilling the requirements for the ability of being folded or put aside on the one hand and fulfilling the acceptance requirement on the other hand.
- The task to be solved by the present invention is the creation of a collapsible or foldable protective helmet for sportspersons, which provide optimum protection for the chosen type of sports and at the same time which is not prima-vista apparent as a protective helmet.
- The solution of the posed task is reproduced in the characteristic part of
Claim 1 with respect to its main characteristic, and in the following claims with respect to further advantageous embodiments. - A more complete understanding of the flexible protective helmet of the present invention may be obtained by reference to the following Detailed Description, when taken in conjunction with the accompanying Drawings, wherein:
-
FIG. 1 shows a longitudinal section through an innermost layer; -
FIG. 2 shows a longitudinal section through an innermost and a middle layer; -
FIGS. 3-6 show different embodiments for the middle layer, in schematic plan views; -
FIG. 7 shows a longitudinal section through an inner, a middle and an outer layer; -
FIG. 8 shows an embodiment of an outermost layer in a schematic longitudinal section; -
FIG. 9 shows a further embodiment of an outermost layer in a schematic longitudinal section; and -
FIGS. 10-11 further show embodiments of the outermost layers in a schematic longitudinal section. -
FIG. 1 shows the longitudinal section through an innermost layer of the foldable protective helmet schematically according to the invention. It preferably consists of a so-called monofilament spacer, with which a monofilament yarn is knitted between two woven orknit layers 2. Such spacers are familiar; they allow being cut and sewn in arbitrary shapes such that an attachedhood 1 that is elastic but mostly permeable to air can be made. On theouter layer 2 of thishood 1, one side of a fastening means 3 is attached at a suitable point, for instance, a fastener by means of sawing or adhesion so that a middle layer according toFIG. 2 can be fixed to this innermost layer without danger of displacement. -
FIG. 2 is the illustration of a second double-walled and gas-tight middle layer 4 with compressed-air inflating possibility. As material for the middle layer, for instance, plastic films made of PU or PVC preferably come in question. For manufacturing themiddle layer 4, for instance, two layers of such a film are laid one over the other and, as shown in theFIGS. 3-6 , welded with one another. From themiddle layer 4, fibre fromhood 1 made of spacers is tied and connected in a detachable manner on the correspondingfixed lock parts 3 on themiddle layer 4 with that of thehood 1. At a suitable point that does not disturb the person wearing the protective helmet according to the invention, there is anair pump 5 for instance that is made of a bulb that can be squeezed together. InFIG. 2 , this is located for instance in the region of the neck. Obviously, any position can be provided, so long as it does not disturb the person wearing the protective helmet. Also a version that is detachable after inflation is appropriate to the invention. Theair pump 5 features avalve 6 each for supplying thepneumatic middle layer 4 with air and one for theair pump 5. Such valves are in fact familiar. - FIGS. 3 to 6 are schematic plan views of embodiments of the pneumatic middle layer, respectively in plan view. It is possible to create the desired concave shape of the
pneumatic middle layer 4 only through attaching weld seams 7 in the air-tight material of thismiddle layer 4 in their inflated states by means of compressed air. This material is preferably, however, already formed by means of cutting so that through inflating it must only be brought to the necessary fitting shape. - Through suitably arranged
interruptions 8 in the weld seams 7, it is ensured that theentire middle layer 4 consists of individual interconnected volumes. According to the invention, cut-outs or slots are likewise provided in thepneumatic middle layer 4, which are confined all round by weld seams 7. Such cut-outs permit vapour diffusion from the scalp through thehood 1 and pneumatic middle layer. - In the inflated state, the
pneumatic middle layer 4 folds out around thehood 1 made of spacers under concurrent formation of many air cushions 9, confined by the weld seams 7, as schematically depicted inFIG. 2 . - In
FIG. 7 —as representative for many others—an embodiment of anouter layer 10 is illustrated. Again, between thepneumatic middle layer 4 and atextile layer 11 of the outer layer 10 a means ofconnection 3 is provided, which allows the twolayers -
FIGS. 8, 9 show schematic cross-sections through such outer layers according toFIG. 7 . Aninner textile layer 11, for instance, made of knit or wovenfabric carrier plates 12. Theseplates 12 are preferably concave shaped. According to their outside contour, they can be formed such that they overlap one another like bricks as depicted inFIG. 8 , or in essence form a smooth layer as shown inFIG. 9 . As materials for theplates 12, above all and according to the invention, one considers shockproof plastics, however, also natural, renewable raw materials like wood, coconut shells or other hard, non-brittle and natural, renewable raw materials and also metals or composite materials made of plastic and metal. InFIG. 9 ,joints 13 are depicted, which serve for compensation of different head sizes and shapes. Should the plates form a surface that is interrupted by thejoints 13, but smooth in essence, then they will be, for instance, cut with polygonal, preferably hexagonal contours. Other shapes are by all means possible and familiar under the term parqueting. - The embodiments depicted in
FIGS. 10 and 11 are also conceivable and included in the invention concept. InFIG. 10 , theplates 12 fixed on thetextile layer 11 are interlaced in one another so that they remain movable relative to one another. - In
FIG. 11 the plates form two overlapping layers:plates 12 a that in essence are made flat, form an inner layer;plates 12 b that are made shell-shaped overlap theinner plates 12 a respectively through their edges. Through this, thejoints 13 are covered according toFIG. 9 . - The
plates 12 are fixed on thetextile layer 11 preferably by adhesive means. Through variation of the size of the adhesive points, within the scope of elasticity of thetextile layer 11 again, different head sizes and shapes can be accounted for, without many such head sizes being provided in the cut and in other production. - In case the protective effect of flexible protective helmet striven for allows this, the pneumatic
middle layer 4 can be omitted. Theouter layer 10, comprising thetextile layer 11 and theplates 12 fixed on it, is then drawn directly over thehood 1. What is essential thereby is that the means ofconnection 3 are attached on the points corresponding with one another. At most, for this approach, a small cut outer layer must be provided.
