ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a glove having excellent tactility. More particularly, the present invention is a glove having seams remote from finger tips and made of material which allows for optimized tactility.
The importance of protecting military pilots against chemical warfare agents cannot be underestimated. It is not difficult to contaminate an entire airfield. Even if the interior of an aircraft can be kept relatively “clean”, the pilot may come into contact with chemical warfare agents on the way to his seat. Epispastic skin poisons, such as, for example, mustard gas (Yperite, yellow cross gas) are especially unpleasant. If the hands have been contaminated, the pilot cannot pilot an aircraft for weeks, because his hands lack all sensitivity. This risk cannot be underestimated, and therefore a great amount of care must be devoted to protecting the hands. So that the glove protects against skin poisons, an adsorption layer must be present, as in chemical protection clothing. In order to avoid local perforations caused by liquid warfare agents, a good hydrophobic and oleophobic finish is recommended. On the other hand, it must be possible for the pilot to operate his instruments unimpeded, which means that a high degree of tactility must be maintained.
A soft glove, which is designed so that it makes it possible to actuate small switches, knobs, instruments, etc. requiring a “fingertip feel”, is, however, also preeminently suitable for a whole range of civil applications.
2. Description of the Related Art
Gloves having a seam along the sides and over the tops of fingertips are known. However, these gloves due to their design, can impede tactility, especially at the finger tips. This is undesirable for use by pilots who require tactility to operate airplane switches and the like.
Gloves that are impervious to certain chemicals are also known. However, the chemically impervious gloves are designed to be impermeable to water vapor. This can cause sweating inside the glove and interfere with tactility. In addition, known chemically impervious gloves are often too thick to allow sufficient tactility.
As a result, there is a current need for gloves that offer a certain degree of protection from harmful chemical agents while maintaining a high degree of tactility.
SUMMARY OF THE INVENTION
An object of the present application is to develop a glove, which in no way impairs the ability to operate a wide variety of instruments and knobs. The glove should be permeable to water vapor.
Briefly stated, the present invention is directed to a glove having a first piece of material for covering a front of a hand and a second piece of material for covering a back of a hand. The first piece of material is formed in the shape of a hand having fingers and extends more than half way around the circumference of each finger and has a narrower tip near a top of each finger. The narrower tip extends beyond the top of each finger. The second piece of material is formed in the shape of a hand having fingers and extends less than half way around the circumference of each finger and below the top of each finger. The first piece of material and the second piece of material are attached at an edge of each piece to form a seam that falls on the back of the hand when the glove is worn.
The object is achieved, on the one hand, by the choice of particularly soft materials and, on the other hand, by a special cut. The latter was developed so that no seams disturb the “fingertip feel”. This was achieved by drawing the material of the underside upward over and beyond the fingertip to a point where seams no longer cause any disturbance.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of the disclosure. For a better understanding of the invention, its operating advantages, and specific objects attained by its use, reference should be had to the drawing and descriptive matter in which there are illustrated and described preferred embodiments of the invention.
