Abstract

The hand grips and/or handles currently in use, employed in sports gear and tooling in general, according to the current state-of-the-art have a non-anatomic shape. The process of the invention described herein presents a new ergonomic object and describes the manufacturing technique for a new hand grip and/or handle furnished with an 'anatomic-isobaric body', devised for making the isobaric distribution of the pressure derived from muscle effort all over the human hand, as it holds the hand grip and/or handle. An integral part of this invention is a special single 'ring', with technical and functional characteristics identical to those of the 'anatomic-isobaric body', adapted to be fit around hand grips and/or handles which furnish equipment currently in use. This new hand grip and/or handle, furnished with an 'anatomic-isobaric body', directly manufactured and/or adapted through the utilization of a special single 'ring' - similarly anatomic-isobaric - is designed to be used in sports gear and tooling in general, providing their users greater comfort, work power, operational efficiency, balance, safety and, specially, control over strokes and movements when using equipment; and all this with less physical effort exerted on the new hand grip and/or handle.

Description

DESCRIPTION
ANATOMIC-ISOBAR IC HANDLE This Patent of Invention concerns a type of anatomic- isobaric hand grip and/or handle to be used by technical sectors of the industry of sports gear and tooling in general
The hand grips and/or handles currently in use and employed in sports gear and tooling in general, in accordance with the current state-of-the-art, has non-anatomic shape, not being molded to fit the typical internal contours of the hand Such is the case with the racquets currently used for court tennis, squash, paddle, polo and golf clubs, baseball bats, hammers, knives, screw¬ drivers, etc
In observing the internal face of fingers and the human hand palm when unrestrained, and under no stress, one verifies that the referred set is neither plain nor flat, but noticeably CONCAVE The so-called "M" described by hand lines (cutaneous hand folds), lies precisely at the bottom of the palm center, surrounded by a set of prominent powerful muscles and by the natural concavity of the fingers The most important muscles of the hand are located at the base of the palm the muscles and flexing tendons of the fingers, on the right, the strong muscles of the thumb the opponent, the flexors and extensors, as well as the interosseous, finally, on the high left, closing the circle, are the muscles and tendons of the metacarpus phalangeal region, where the other fingers are inserted
Now, the currently used hand grips and/or handles, whose design has remained basically unaltered for over a century, go against the basic facts of hand anatomy, since they do not correctly conform to an extremely important circumstance of human anatomic position, namely they do not. mold themselves to the anatomy of the palm and finger muscles of the human hand and , therefore they reduce the muscle stress area by concentrating pressure on a few points
As a direct consequence of this situation, the hand palm of sports people and workers who, with repetitive movements , make use of equipment furnished with the current hand grip and/or handle, shows the appearance of blisters which tend to evolve into callosities through repeated handling of that equipment.
Thus, due to a reduced stress area, muscle fatigue ensues, in association with the increased workload all along the arm This results in substantial reduction of the CONTROL of the operator over the instrument, with associated loss of efficiency of strokes and increased risk of accidents and, finally, reduced productivity with the appearance of early fatigue
Such is the state-of-the-art. If one opens the hand and has an object with appropriate anatomic shape placed on it, and subsequently tightly closes the hand, one will notice that the object is involved comfortably and safely by the palm and finger muscles. The shape of the object will perfectly mold itself to the anatomy of the hand palm and fingers, which will be exerting over the object an evenly distributed pressure or ISOBARIC PRESSU RE
Thus, the invention described herein is a new "ANATOMIC-ISOBARIC HAND GRIP AND/OR HANDLE" , characterized by featuring anatomic prominences and depressions in a shaft of resistant materials, sculpted on the length extension of the hand grip and/or handle, in the most convenient position regarding the ergonomics of each different type of equipment; also by having a rounded and/or geometric section; by being fit either for right-handed or left-handed persons; by being designed for the use in technical sectors of the industry of sports gear and tooling in general, and by creating in its set length/section an "anatomic-isobaric body" aimed at making the isobaric distribution of the pressure derived from muscle effort all over the human hand, as it holds the hand grip and/or handle. The manufacturing process for the ANATOMIC-ISOBARIC
HAND GRIP AND/OR HANDLE is characterized by the sculpting of anatomic prominences and depressions in a shaft of tough material such as synthetic and/or natural resins, carbon fibers, wood, elastometers, steel, ceramics, fiberglass, conjugate materials, etc . , by being such anatomic prominences and depressions sculpted on the extension of the hand grip and/or handle length, in the most convenient position, in erqonomic terms, by featuring a rounded and/or geometric section, by the ability of its manufacturing system to include drilling or lathe-turning, or casting, or injection, in every case depending on the type of equipment and material employed, by its coating being rigid and/or flexible, materials being used for that purpose such as leather, elastometers, synthetic and/or natural materials or other materials, by thus creating, in its length/section set an "anatomic-isobaric body", also by such "anatomic-isobaric body" being moldable through the use of the special single "ring", final ly, by aiming at the isobaric distribution of the pressure derived from muscle effort all over the human hand, as it holds the hand grip and/or handle
The position of the "anatomic-isobaric body" in the handles of instruments, the measure ratio between its virtual diameter and that of the other segments of the handle, its length and building material , are details which may vary as a function of the specific type of instrument, of more economical manufacturing methods, of the evolution of materials techniques and of the practical experimentation of each specific piece of gear For these reasons such details are not defined herein The "anatomic-isobaric body" , which will conform to the classical standards as for sizes, as well as to the ergonomic principles and anatomy of the hand's inner face, shall be placed in the best possible posιtιon( s) along the handle, aiming at lowering vibration of the equipment when submitted to reactive forces and at decreasing the physical effort spent by the hand, the forearm, the arm and shoulders of the operator, as he/she strikes with each different sport or work gear, in accordance with the convenience of isobaric effort of the whole hand. The aforementioned special single "ring" is characterized by a special single "ring" manufactured from resistant materials, and which is introduced and adjusted to the hand grip and/or handle already in use or new; by reproducing the same outer shape and the same physical-mechanical effects of the "anatomic-isobaric body" ; by such ring being also fixable at any position along the length of the hand grip and/or handle, and also by aiming at the isobaric distribution of the pressure derived from muscle effort all over the human hand, as it holds the hand grip and/or handle. The manufacturing process of a special single "ring" is characterized by the possibility of building it from synthetic and/or natural resins, carbon fibers, elastometers, fiberglass, etc...., by its being manufactured to be introduced and adjusted to the hand grip and/or handle of pieces of equipment already in use; by reproducing the same outer shape and the same physical- mechanical effects of the "anatomic-isobaric body" : by such ring also being fixable at any position along the length of the hand grip and/or handle, by means of pressure, glue, screws, or other devices and, finally, by aiming at the isobaric distribution of the pressure derived from muscle effort all over the human hand, as it holds the hand grip and/or handle. The uti lization of this special single "ring" will give the hand grip and/or handle already in use the same outer shape of the "anatomic-isobaric hand grip and/or handle" , according to the drawing in Picture 1 Also, this "ring" may even be built out of a special bui lding material , moldable by pressure of the user's own hand
This ring will have the advantage of being positioned at any part of a. new hand grip and/or handle, satisfying the personal preference of each user of that particular piece of gear, and it will also be supplied as a single item in various standard sizes, to be placed on the handles of equipment already in use This special single "ring" is an integral part of this Patent of Invention
The new hand grip and/or handle may have different diameters for its n_ segments, as shown by the drawing in Picture 1 , enclosed
