Shoe, in particular motorcyclist shoe

The invention relates to a shoe, in particular a motorcyclist's shoe, made of leather, which has reinforcements in areas of high stress.

Work shoes with reinforcements, for example protective caps made of leather or steel, are known »They should both be higher Withstand stress and protect endangered areas of the foot, namely toes or the instep. In particular are also known motorcyclist shoes, for example enduro boots, which should not only be suitable for normal use, but also in the event of an accident or a fall To fulfill protective function. According to accident statistics, feet are also particularly at risk when riding motocross. More and more motorcyclists are therefore interested in getting clothing that is also suitable for the road Has protective function. In the event of a fall from a motorcycle, there are special problems in the foot area due to the fact that that either the driver's foot is trapped under the falling machine, which is dragging across the ground, or as a result, that if he falls he tries to get away from the machine loosen and then drag yourself over the ground at a comparable speed due to the friction. It surrendered high friction loads in the area of the ankles, ankles and in the area of the toes when the shoe is rubbed the ground, which usually consists of an asphalt road surface.

So far, motorcycle rider shoes have been made of leather, with protective reinforcements - apart from that caused by the shifting process stressed area of the shoe - possibly by double Leather layers were provided. Experience has shown that the shoes only inadequately fulfill protective functions. she In the event of a fall, they often chafe through completely, are torn apart at the seams and are not suitable for being strong To prevent abrasions from the skin. Abrasions occur, especially in the ankle area, until they are exposed of the bone. Leather reinforcements are therefore not the appropriate means, especially for shoes with a good protective function Provide motorcyclists.

The invention is based on the object of a shoe, in particular for motorcyclists to propose high safety criteria with regard to avoiding the disadvantages mentioned Has abrasion, tear and seam resistance and is above all suitable, even with heavy loads, the foot reliably to protect. The use of steel caps, as they are known from the work shoe sector, should be used because of the requirement avoid developing a shoe that is light, elastic, yet durable and safe.

The object is achieved according to the invention in that the shoe Q) is constructed in three layers at least in the area of each reinforcement, the inner layer made of leather, the intermediate layer made of flexible, tear-resistant plastic fabric that is heat-resistant up to temperatures> 280 ° C and the outer layer again made of leather . The intermediate layer should preferably consist of a fabric made of polytetrafluoroethylene (PTFE). The double leather processing including polytetrafluoroethylene intermediate layer achieves an extraordinary protective effect. For example, if the driver falls off his motorcycle

if he slips the floor or if his foot is trapped under the machine dragging across the floor and runs the risk of Suffering painful abrasions that take a long time to heal first rubs through the outer layer of leather. the PTFE insert exposed to the stresses in it has unusual high resistance to heat and can cope with the frictional stresses due to extremely low temperatures Frictional and adhesive properties. The low coefficient of friction of PTFE fabric prevents any chafing of the intermediate layer, so that the leather inner layer remains intact. In spite of the high temperatures, burns of the skin do not occur. The unaffected inner layer prevents Burns, skin and bone abrasion on the foot and lower leg (depending on the height of the shoe).

Preferably, the PTFE fabric consists of a double-woven fabric made of PTFE fiber and cotton. For extreme demands can also be made of PTFE fiber alone or combined with fiberglass, for example, can be used with a fiberglass-phencl laminate. This material is able to withstand temperatures reliably absorb up to 316 ° C without changing its properties.

According to an expedient embodiment of the invention, it is proposed that to sew the three-layer reinforcement with the shoe seams, for example towards the sole, with a seam reinforcement can be achieved in that the sewing thread consists of polytetrafluoroethylene fiber thread. In addition, can Large-area quilting to increase the abrasion resistance of the three-layer reinforcements.

In areas of application where the foot must also be protected against impact with a solid object, an additional

Before upholstery, applied inside or outside, advantageous. It can therefore provide protection in the ankle and lower leg area (shin) of a raised shoe or boot Expanding padding can be applied to the three-layer reinforcement inside or outside. In general, there are reinforcements in the area of the outer edge of the foot, the toes, the large ball of the foot and the ankle (inside and outside).

In a preferred embodiment, the shoe according to the invention consists of nappa leather with a thickness of 1.8 to 2.5 mm for the inner and outer layers and a polytetrafluoroethylene intermediate layer of a G
preferably about 480 g / m ^e.g.

len intermediate layer of a weight between 350 and 500 g / m,

Overall, it is achieved with the shoe according to the invention that the safety properties are significantly improved and a actual protection of the foot is guaranteed even under extreme loads.

Further details, features and advantages of the subject matter of the invention emerge from the following description the accompanying drawing, in which a motorcyclist sports shoe according to the invention is shown schematically. In the The drawing shows a side view, a bottom view and a sketch of the structure of the reinforcement. The shoe 1 consists of nappa leather with a thickness of 1.8 mm. It has an inner lining 2, which is the sketch below in the drawing is removable. In the toe area 3 and in the ankle area 4 a reinforcement 5 is indicated by a dashed line Representation marked. Each reinforcement consists of the inner layer 6 formed by the shoe 1, the one arranged on it Middle layer made of polytetrafluoroethylene fabric 7 and a leather outer layer 8 made of 1.3 mm thick nappa leather. The polytetrafluoroethylene fabric liner 7 has a strength of

about 0.5 mm, which corresponds to a weight of 480 g / m.

The reinforcement 5 in the ankle area 4 is also inside with a padding, not shown, as a fall pad Mistake. In addition, it can be seen from the view from below, in which the sole of the shoe has been omitted, that the reinforcement 5 is drawn into the toe area 3 in the sole area and thereby also comprehensively protects the ball area. If necessary, the hook area of the foot can also be provided with the desired three-layer structure.
