DESCRIPTION:
BRIEF SUMMARY
The invention relates to a hand protector for use in pugilistic sports, having a flexible cover of leather or imitation leather and inserted therein a one-piece, elastic padding of foam.
A boxing glove designed according to these principles is known from German published non-prosecuted application DE-OS 31 47 997. There, a pre-formed flat body of a closed pore foam material is inserted into a corresponding cover, which does not have a separate section for the thumb, to reduce the danger of injury in boxing.
The closed pore foam material used, although highly elastic, shows almost no damping effect or absorption of blows, it only resiliently returns or conducts the applied force practically unmodified.
In addition, this boxing glove is relatively impractical, since, although it provides basic protection for the thumb by enclosing the thumb in the main glove opening and avoids particularly the bending-out of the thumb during the fight, this has proven to be not very useful for the freedom of movement of the hand.
Conventional boxing gloves do provide an elastically resilient filling; this filling, however, consists of fibers and/or plastic foam which offer only limited absorption of blows on the one hand, and on the other hand they are compressed within the cover and may be displaced, especially at the hitting areas, so that after some use the blow padding is no longer ascertained.
It is therefore an object of the present invention to provide a hand protector for use in pugilistic sports such as, for example, boxing, kick boxing, Thai boxing and other all-contact types of fighting sports, which, although basically similar to a boxing glove on the outside, assures optimal reduction of impact forces, so that whiplash accellerations to the brain are considerably reduced. Additionally, this hand protector is intended to be very resistant to fatigue, so that there is no fear of a change in the consistency and/or distribution of the filler.
To attain this object it is provided by the invention to make the padding from a one-piece shaped body of highly cushioning, open pore polyurethane foam material, which is arched crosswise, corresponding to the natural arch of the hand, on the outside and inside over its entire length, and in the longitudinal direction is arched downwardly at an angle of approximately 90 in the region of the rear knuckles and is reinforced in this region. A flat thumb may thereby be connected laterally in the region of the palm of the hand, the thumb region archingly covering the upper surface of the thumb within the hand protector cover.
A highly cushioning effect is realized with such an insert of open pore foam material, i.e the impact forces are reduced to a high degree and are dissipated, thus simultaneously reducing the whiplash effects, which have a particularly negative effect on the brain. Additionally, the provided shape of the foam body, after insertion into the cover of the glove, results in a form which approximates the position of a curved hand made into a fist, so that only small additional force is required to close the hand completely.
It has proven particularly useful when in the region of the bulge of the plastic foam shaped body the radius of curvature of the outer surface is no larger than the radius of curvature of the inner surface and that the outer and inner surfaces approach each other approximately asymptotically towards the finger tips on the one end and towards the wrist at the other end. This creates reinforcement in the main area of the hand protector without necessitating discontinuous material transition regions.
It is furthermore useful to provide a cup-shaped arch on the foam body laterally in the region of the index finger opposite the tip of the thumb which covers the thumb when the fist is made. By means of this, blows, which impact the thumb from the front and which might cause sprains, are safely prevented.
In order to also allow closing of the fist practically without exertion of force it is useful to provide the foam body on its underside in the region
