Definitions

• the invention relates to a protector for protecting an exposed during exercise body part of a person from shock, shock or injury with the contours of the body part to be protected at least partially adapted planar molding of soft-elastic plastically deformable material, and a method for its preparation.
• Sports protectors especially in the form of elbow pads, knee pads and shin guards are now standard equipment not only professional handball and football players. Even in amateur sports operation is hardly waived for reasons of safety on such protective equipment. Also in the leisure and fun sports field, for example, skateboarding and inline skating driving sports protectors are used to protect against abrasions and bone fractures on a large scale.
• baffle plate made of impact resistant plastic high fracture toughness, which is lined with foam and / or textile padding and is attached either with bands over the tibia or sewn onto the front of a stocking, round-knit textile part.
• shin protector for example those with air-filled chambers, into which foam strips can be inserted in order to improve the damping properties ( DE 8007129 U1 ), those in which a hard impact shield made of thermoplastic material is bonded to a second material layer having a honeycomb-like cellular structure ( DE 9312308 U1 ) and those in which a fiber composite part of a highly elastic matrix and is used in these inserted reinforcing fibers, for example in the form of a hybrid weave of glass and aramid fibers ( DE 4120135 A1 ).
• bandages are naturally very light and flexible, provide a high level of comfort, but are in terms of their protective effect only slightly resilient and provide little protection against impact and impact injuries.
• the invention is therefore based on the object to meet this need and to provide a sports protector, on the one hand as light as possible, flexible and thin, but on the other hand ensures a high impact protection. Moreover, such a sports protector should be as simple and inexpensive to produce in a suitable for high volumes automated processes.
• the protector according to the invention is characterized in that the body part to be protected at least partially adapted planar molding of soft-elastic plastically deformable material of at least one Integralschaum Mrs each having a foamed core and two, the core sandwiching, unfoamed outer layers, a smooth, the Having to be protected body part facing inner surface and a relief-like structured outer surface.
• the molded part consists of one or more Integralschaum füren, which in itself the characteristics of a soft, shock-absorbing foam and combine two impact resistant, but plastically deformable, non-foamed plastic cover layers, eliminating the need to produce a composite of different plastic materials, which not only the production of the protector of the invention over the prior art is much easier and cheaper, but also the material thickness of can be chosen much lower in advance, which in turn reduces the weight and increases the comfort, without worsening the mechanical properties and thus the protective effects.
• a "relief-like structured outer surface” is understood according to the invention to mean a surface which has a three-dimensional structure formed by specifically designed, shaped and positioned depressions in the outer surface and elevations from the outer surface.
• Recesses can be formed by grooves or arbitrarily shaped area depressions, elevations by webs or arbitrarily shaped areal elevations and form a picture-like pattern in each case or by any desired combinations of linear and area-shaped elevations and depressions. Since all depressions mean a weakening and all increases an increase in material, softer zones develop in the area of the depressions and more rigid zones in the area of the elevations.
• the conformability of the sports protector to the part of the body to be protected e.g. the shin or ankle
• optimizing the mobility z. B. increase in the joints, but at the same time also very selectively increase the shock and impact resistance and mechanical stability in some areas.
• the relief-like structured outer surface thus serves a dual purpose.
• the flexibility of the molded part can be specifically controlled in the longitudinal and / or transverse direction so that the protector can cling as ideally as possible to the predetermined contours of the body part to be protected, and secondly, infinitely many imaginative designs can be created with the aid of a relief-like structure realize the outer surface of the molding.
• the molded part consists of a single integral foam layer.
• the molded part consists of two or more integral foam layers with different physical properties, for example, with different hardness, different density, different flexibility and / or with a different resilience after plastic deformation. In this way, all conceivable combinations of hardness, density, flexibility and resilience can be realized in a simple and cost-effective manner.
• the core of the at least one integral foam layer is foamed open-celled, which favorably influences the plastic deformability and the resilience.
• the integral foam layer (s) is / are preferably made of polyurethane (PUR) or a modified polyurethane, namely a polyurethane elastomer.
• polyurethanes are suitable for this purpose, the expert, for example Ullmann's Encyclopedia of Industrial Chemistry, 6th Edition, Vol. 28, p. 667 ff , remove.
• Particularly suitable are PU molded foams and those in which at least one of the plurality of integral skin layers is a layer of PUR cold foam.
• Cold foams are about 20% more dense, and thus heavier than hot foams, but they have a higher elasticity than hot foams, which results in a narrower hysteresis loop.
• the molding preferably has a hardness gradient that increases from the inside out so that the innermost layer facing the body part has the least hardness and the outermost layer has the greatest hardness.
• This simulates a layer structure and a division of the physical properties, as it is present in the conventional composite materials with impact-resistant protective shield and soft padding, although according to the invention actually no composite of several, completely different components is present.
• the hardness of the molding according to the invention is preferably 10 to 50, particularly preferably 20 to 40 Shore A.
• the thickness of the molding is preferably 1 to 12 mm, more preferably 2 to 7 mm.
• the relief-like structured outer surface on a raised and recessed portions existing pattern.
• a particularly thick, raised portion in polygonal, round be provided oval or in drop form.
• a thickened, raised section may be present in the area of the elbow joint.
• raised portions may be formed by mesh or spider web-like structures, while recessed portions may be in the form of grooves or indentations of any kind.
• the thickness of the molding is preferably about 5.5 to 12 mm, and in the region of the recessed portions is preferably about 1 to 5 mm.
• the bulk density of the integral foam layer (s) of the protector according to the invention is preferably about 0.2 to 0.4 g / cm 3 .
• the inner surface of the molded part facing the body part to be protected is preferably flocked or laminated with a textile layer, wherein any skin-compatible fabric in the form of a woven, knitted or knitted fabric of natural or synthetic fibers or mixtures thereof can be used for lamination.
• a skin-friendly, sweat-wicking and cooling fabric or similar knit fabric is used to laminate the inner surface of the molded article with a textile layer.
• the relief-like structured outer surface of the molding may be at least partially painted or laminated with a decorative plastic film. Since the raised and recessed portions of the relief-like structured outer surface can be colored differently, regardless of whether by painting or by film lamination, in this way color-attractive designs can be realized in a cost effective manner. There are no limits to the color design; Therefore, club logos, manufacturer logos, country and association colors, numbers, letters and identification marks of all kinds can be integrated into the relief-like structured outer surface of the molded part.
• the protector has means for releasable attachment to the body part to be protected.
• These may be textile bands, elastic bands, leather straps and the like, which can be adjusted, closed and opened in width with closures of all kinds, preferably with Velcro fasteners.
• those embodiments are particularly preferred in which the protector according to the invention acts directly on a tubular or hoselike shape Textile carrier has been applied, wherein the textile layer on the inner surface of the molding is thus part of a knitted or knitted fabric.
