    PROTECTION ELEMENT
    This invention relates to a protective element for protecting at least a portion of a zone of the human body that is exposed to external loads, including flexible, gas-filled cells.
    This invention also relates to a shoe and a stocking or sock which comprises such a protective element.
    This invention further relates to the use of bubble plastic as such a protective element.
    There are already different types of protection elements for protecting at least a part of an area of the human body that is exposed to external loads. These can also be adapted to a specific zone and specific external loads occurring.
    This invention relates more specifically, but not limitingly, to protection elements for protecting at least a portion of the area around the tibia in ski boots or shoes for playing hockey or skates, etc. It is known that this area during skiing, snowboarding , hockey, skating and similar sports are heavily taxed. Various protective elements can be found in the patent literature to protect at least part of this zone.
    For example, EP 1 316 268, EP 0 372 297, WO 2008/011686 and US 4,008,350 describe soft inner linings for ski boots that serve as a protective element. Such soft inner liners, however, usually do not offer adequate protection. These are in fact designed as standard for a certain size of ski boot and are not adaptable to other dimensions and / or ratios of the areas of the human body to be protected. In the case of one person, these can be too loose, as a result of which friction still occurs between parts of the foot or the lower leg relative to the ski boot, so that scrapes can occur. In the case of another person, these can again be too tight, so that these protection elements can still provide additional pressure on different areas of the foot or lower leg, with possible bruises as a result.
    Gel cushions were also developed analogously to be fitted as a protective element in ski boots. In such gel pads, the gel moves in the gel pad from zones where there is less space between the foot or lower leg and the ski boot to zones where there is more space between the foot or lower leg and the ski boot. US 5,007,111 describes a further embodiment of such a protective element, wherein gel or air is arranged in cells, wherein this gel or air can migrate via channels between these cells. By redistributing the gel depending on the shape and dimensions of the foot and the lower leg that are fitted in a specific ski boot, the protective effect of the protective element is thus already slightly adjusted to the specific shape and dimensions of this foot and the lower leg. In practice, however, this redistribution is not sufficient to obtain a protection adapted to the specific shape and dimensions of the foot and lower leg and the specific shape and dimensions of the ski boot.
    All these protective elements according to the state of the art are therefore not or not sufficiently adaptable to other dimensions and / or ratios of the relevant zone of the human body or to other dimensions and / or ratios of the respective ski boots or similar shoes or clothing items.
    Protective elements adapted to these specific shapes and dimensions of the human body and ski boots have already been developed. EP 0 629 358 describes such an adaptable protective element, designed as an inner liner for a ski boot, which is filled with a liquid that can be cured into flexible foam, which is provided for, after fitting the foot of the person who will use this ski boot in harden this inner lining and in the specific ski boot. However, this solution is an expensive and cumbersome solution, so that it has hardly found any practical application.
    The object of this invention is therefore to provide a more cost-effective and easily adaptable protective element to the specific dimensions and proportions of the human body and / or a garment, for protecting at least a part of a zone of the human body exposed is subject to external taxes.
    This object of the invention is achieved by providing a protective element for protecting at least a portion of a zone of the human body that is exposed to external loads, including flexible, gas-filled cells, wherein at least a portion of said gas filled cells are foldable under a compressive force that is greater than any of the aforementioned external loads.
    With such a protection element it is always possible to provide sufficient cells in a zone where larger external loads can occur, in order to sufficiently protect this zone against these loads, or in a zone with a greater distance between the human body and any clothing item, in order to avoid friction of the garment with respect to the human body. In zones where there is less space between the human body and a possible item of clothing, such as, for example, certain zones in a ski boot, a number of cells can be swung open, so that extra pressure on the human body in these zones is avoided. This folding open can, for example, be carried out actively by exerting a suitable pressure force on these cells, including folding these cells open. This folding open can also occur, for example, because the extra pressure in a zone where there is less space between the human body and any clothing item, is greater than the pressing force under which these cells are designed to be open.
    The said cells preferably fold, when pressed at 100 mm / min, open at a load between 10 and 60 N / cm 2, more specifically at a load between 10 and 45 N / cm 2, even more specifically at a load between 10 and 35 N / cm 2 and even more specifically with a load between 18 and 20 N / cm 2.
    The said gas in the cells of such a protective element is preferred air.
    In an easily realized embodiment of a protective element according to the present invention, the cells are made of foil. Even easier to manufacture is a protective element made entirely from foil.
    Depending on the application, a thicker or thinner film can be used for this purpose and / or the cells can be filled with more or less gas.
    An alternative embodiment of a protective element according to the present invention is not entirely made of foil, but comprises a moisture-permeable cloth, to allow perspiration through the protective element.
    The largest dimension of the cells of a protective element according to this invention is preferably 3 to 1000 times smaller than said zone, more specifically 5 to 100 times smaller than said zone, and even more specifically 5 to 20 times smaller than said zone zone.
    The dimension of the cells perpendicular to the said zone is preferably 2 to 5 times smaller than the largest dimension of the cells. This dimension is even more preferable about 2 to 5 mm.
    The size of the cells is preferably found as a compromise between, on the one hand, making the cells as small as possible in order to realize a transition that is as nuanced as possible between a zone with separate non-opened cells and a zone with open-folded cells and, on the other hand, making the cells as large as possible. to provide sufficient buffering per cell against occurring external loads.
    A specific embodiment of a protective element according to the present invention comprises cells of different shapes and / or different sizes.
    The shape and / or size of the cells can then, for example, be adapted to different load zones, within the zone that is exposed to external loads.
    All possible forms for the cells are conceivable. More specifically, the cells may, for example, be made with a circular cross section or an oval cross section or a hexagonal cross section, etc.
    Preferably at least a part of the cells of a protective element according to the present invention comprises a round cross section in order to optimally absorb the loads.
    A further specific embodiment of a protective element according to the present invention comprises two or more layers of cells.
    In this way, for example, various embodiments can be worked out depending on the expected gradation of external loads. Professionals can expect larger external loads and multiple layers of cells may be required. For amateurs, smaller external loads are to be expected and one layer or several layers of cells may be sufficient.
    It is also possible to vary the number of layers of cells within a protective element in order to provide more layers in zones that will be loaded more and fewer layers in zones that will be loaded less.
    A preferred embodiment of a protective element according to the present invention is designed as an insert for fitting into a garment.
    More specifically, it can then be adapted to fit into a shoe and more specifically a ski boot. This can also be adapted to be placed in a shoe for playing hockey or in a skate, etc.
    An even more preferred embodiment of a protective element according to the present invention can be cut to size, so that it can be easily adapted to the desired applications or to the specific person who will use this element or to the garments in which this protective element will be fitted.
    Alternatively, different protection elements can be marketed, with shapes and sizes adapted to specific applications.
    In a specific embodiment, the said zone which is to protect a protective element according to the present invention is the tibia and / or the ankle.
    For use in ski boots or shoes for playing hockey or ice skates, etc., the part of this zone that is then preferably screened extends over the tibia, up to the upper edge of the ski boot and up to the transition between the lower leg and the foot. Specifically, it can further extend until it covers the ankle on both sides.
    Furthermore, preferably at least one side of a protective element according to the present invention is of substantially flat design. This surface can be curved or can be curved. In use, this surface preferably takes the form of the zone of the human body to be protected.
    A particularly useful protective element according to the present invention is provided with a self-adhesive layer.
    This self-adhesive layer is preferably designed as an adhesive layer with adhesive adapted to be applied to the skin. This self-adhesive layer can optionally also comprise an adhesive layer which is adapted to be applied to an item of clothing. Instead of an adhesive layer, any other fixation material can be provided that is adapted to releasably attach this protective element to the skin or to an item of clothing.
    Such a protective element according to the invention could also be elaborated in combination with existing protective elements from the prior art. Thus, for example, a protective element according to the invention can be provided in a layer on an existing protective element according to the state of the art. It is also possible, for example, to develop a protective element according to the invention in a zone adjacent to an existing protective element according to the state of the art into a new protective element, so that a part of the zone to be protected is protected with the aid of the protective element according to this invention, while another one part of the zone to be protected is protected with the help of the existing protection element according to the state of the art.
    This invention is also achieved by providing a stocking or sock that includes a protective element according to the present invention.
    This invention is furthermore also achieved by providing a shoe which comprises a protective element according to the present invention.
    Finally, this invention is also achieved by providing for the use of bubble wrap as a protective element according to the present invention. A protective element according to the invention made of bubble plastic is a cost-effective alternative to protective elements. Moreover, this can easily be adapted to specific dimensions and / or forms of zones of the human body and / or clothing, because on the one hand the gas-filled cells of the bubble plastic can be peeled open under a compressive force and on the other hand such bubble esplastic on size is cutable.
    This invention will now be further elucidated on the basis of the following detailed description of preferred embodiments of a protective element according to the present invention. The purpose of this description is to give only illustrative examples and to indicate further advantages and details of these protective elements, and thus can in no way be interpreted as a limitation of the scope of the invention or of the patent rights claimed in the claims.
    In this detailed description reference is made to the accompanying drawings by reference numerals, in which - figure 1 shows a sketch of a front view of a lower leg provided with an embodiment of a protective element according to the present invention; figure 2 shows a sketch of a left side view of the lower leg provided with an embodiment of a protective element according to the present invention from figure 1; figure 3 shows a sketch of a right-hand side view of a part of the lower leg provided with an embodiment of a protective element according to the present invention from figure 1.
    The protective element (1) as sketchily depicted in Figures 1 to 3 is adapted to protect a zone of the human body around the tibia, this zone extending further over the ankle. This zone is heavily used for skiing, snowboarding, hockey, skating and similar sports. The protective element (1) is here provided for fitting on the aforementioned zone, and putting on a ski boot or shoe for playing hockey or skate, etc., so that the protective element (1) is located between the lower leg and a ski boot. or shoe for playing hockey or skate, etc. The protective element (1) then extends to the upper edge of the shoe and to the transition between the lower leg and the foot. This protective element (1) comprises flexible, air-filled cells (2). Instead of air, these cells (2) could just as well be filled with another gas. This other gas is then preferably not harmful to the environment. These cells (2) are designed to fold open under a pressure force. The compressive force at which they open is greater than any of the external loads that are exerted on said zone when skiing.
    A protective element (1) as shown can, for example, be made from bubble plastic by cutting to size bubble plastic. In this case the protective element (1) is entirely made of foil.
    In tests with protective elements (1) made from bubble plastic that lends itself perfectly to the said application, the cells (2), when pressed at 100 mm / min, were between a round stamper with a surface of 10 cm 2 and a plate, in a test atmosphere of 65 ± 5% relative humidity and a temperature of 20 ± 2 ° C, and when pressed down to 0.1 mm of the bubble plastic, foldable at loads between 10 and 35 N / cm2 and with even more suitable bubble plastic between 18 and 20 N / cm 2.
    Depending on the application, however, it may also be desirable to manufacture this protective element (1) from more rigid foil, or partly not from foil, but to work it out in, for example, a moisture-permeable cloth. With such a moisture-permeable cloth, perspiration through the protective element (1) can be made possible. The cells (2) themselves are then preferably made of plastic, because they must be air-impermeable.
    The largest dimension of the cells (2) is preferably 3 to 1000 times smaller than said zone, more specifically is 5 to 100 times smaller than said zone, and is even more specifically 5 to 20 times smaller than said zone. The dimension of the cells (2) perpendicular to the said zone is then preferably 2 to 5 times smaller than the largest dimension of the cells (2).
    The cells (2) of the protective element (1) shown are all of similar shape. Depending on the application, it may be desirable to provide different shapes and / or different dimensions of cells (2). The shape and / or size of the cells (2) is preferably determined in function of the expected external loads occurring. All possible forms for the cells (2) are conceivable. However, the cells (2) are preferably provided with a round cross-section, such as the cells (2) in the protective element (1) shown.
    The illustrated embodiment of a protective element (1) according to the present invention comprises only one layer of cells (2). However, depending on the application, two or more layers of cells (2) may also be desired. The number of layers of cells (2) can also be varied within a protective element (1) in order to be able to absorb the external loads occurring optimally. When testing with a protective element (1) made of bubble plastic, protective elements (1) could be obtained in this way, whereby the cells (2), when pressed at 100 mm / min, between a round pestle with an area of 10 cm 2, at a test atmosphere of 65 ± 5% relative humidity and a temperature of 20 ± 2 ° C, folding open at loads between 14 and 42 N / cm 2 when these comprise two layers of cells (2) compressed to 0.2 mm, and, more preferably, such embodiments at loads between 24 and 32 N / cm 2. In embodiments comprising three layers of cells (2), the cells (2) flipped open upon impressions up to 0.3 mm, with loads between 22 and 58 N / cm 2 and, more preferably, such embodiments with loads between 28 and 46 N / cm cm2.
    The protective element (1) shown is placed on the skin of the lower leg and foot. For this purpose, this protective element (1) can for instance be provided with a self-adhesive layer, with glue which is adapted to be applied to skin. Other fixation materials are also conceivable. The side of the protective element (1) facing the skin is flat. The other side can also be flat.
    Instead of on the skin, this protective element (1) can also be applied to a stocking, for example. This protective element (1) may also be incorporated in the lip of a ski boot or shoe for playing hockey or skate, etc., or may be worked out as an insert for fitting in the ski boot or shoe for playing hockey or skate, etc.
    A protective element (1) according to the invention can of course also be worked out in other embodiments for other applications. For example, such a protective element (1) can be worked out to protect the head in a helmet better and more adapted to the shape and dimensions of the head. For example, knee pads can also be worked out as a protective element (1) according to the invention in order to protect the knees of workers who frequently have to sit on their knees. A multitude of other applications are also conceivable.
