Abstract
An ergonomic glove, fingered or fingerless, is provided for use with devices that require gripping such as ski poles, dumbbells, and bicycle handlebars. The glove shape is of a sports-fitted glove with built-up areas on the thumb, fingers, and palm, whereby when the wearer grips an item, the thumb is supported and the hand and wrist are in a neutral position generally aligned with the forearm. A thumb retainer is provided to position and support the thumb while bent. The glove is also provided with a padded insert or exsert of two different constructions, both having three portions, which insert or exsert acts to restrict the contraction of the successive fingers at a gradual rate. The insert/exsert causes the knuckles to be in linear alignment. The glove promotes improved alignment and stabilization of the user's body parts and in particular shoulders, hips, legs, etc., for greater stability and movement efficiency.

DESCRIPTION OF THE PREFERRED EMBODIMENT
(18) The ergonomic glove 10 of the first embodiment of this invention is seen in
(19) Turning now to
(20) Thumb support 30, also disposed within standard glove 11, will be discussed infra. Thus it is seen that the insert 12 has three portions, the palm portion 14, the intermediate or motion limiting portion 39, seen in detail for all four fingers in
(21) The glove 11 is any standard thinly lined or any unlined glove such as an athletic glove or driving glove. Such a glove can have a leather or artificial leather or other suitable material outer layer such as 60 seen in
(22) The insert 12, while a unitary structure formed from a soft polyurethane, flexible foam as noted, possible other materials, could be non-flammable or flame resistant materials such as leather, Kevlar, nomex or soft rubber has three portions. The first is the digit or finger portion 19 which has four sections, one per finger, each of which are designated 20,21,22,23, with an added L or R designation to denote the left or right-hand version of an insert. The second portion is the intermediate or crease portion 39 which also consists of four sections designated 41, 42, 43, 44, of
(23) In
(24) Each section of the first portion 19 of the insert 12 extends from about the metacarpophalangeal crease of each finger rearwardly in the direction toward the wrist to the respective inter-digital pad of that finger. Each first portion section may have an arcuate leading edge as shown or one linearly cut if desired.
(25) The intermediate portion of the insert is portion 39 and it too has four sections, one section for each of the respective fingers excluding the thumb. This portion is depicted grossly magnified in the subfigures 3A,3B,3C,3D, of
(26)
(27) Each crease 39 comprises two segments depicted here as flat; namely, the first portion of the respective finger and the digital pad or upper area of the palm portion with a crevice there between. From these subfigures, it is to be understood that each crevice in the respective crease of the four fingers of the insert is narrower and shallower in a progression from the little finger toward the thumb. Compare
(28) Reference to the sub-figures shows that the nomenclatures 44U,43U,42U,41U, designators all refer to the upper segment or inclined wall of the respective creases shown in
(29) The reader is again referred to
(30) The bottom surface 31 supports the thumb both slightly above and slightly below the crease between the distal and proximal phalanxes of the thumb. Reference should also be made to
(31) Support 30 may be made of a flexible material such as nylon or other polyamide thus the thumb while supported is able to articulate. Support 30 is sewn or glued in place between the lining and the outer layer of the conventional glove 11. If the glove 11 is unlined, support 30 may be attached by a suitable adhesive to retain it in its desired position.
(32)
(33) The insert 12 in
(34)
(35) While only one hand has been discussed and only one inventive glove shown for this first embodiment, it is best if the glove of this invention is used in matched pairs, one for the right hand and one for the left hand. That way maximum benefit is obtained. The second embodiment should also preferably be used in pairs
(36) The glove shown in
(37) The second feature addition shown in this
(38) Applicant is the inventor of U.S. Pat. No. 5,979,015 issued Nov. 9, 1999. That patent pertained to a pair of handgrips. The channels of the insert of this ergonomic glove, as disposed in the palm of the glove, create the same effect upon the handgrips as the fingers contract during the course of work as occurs when the fingers are placed upon a set of the grips or upon the grips as incorporated into other structures such as ski poles or hand tools. As the hand wraps around the grip, the fingers and thumb are placed or guided to precise positions relative to the grip but now within the glove as the ergonomic glove is wrapped around a work surface.
(39) 1. The thumb shelf which supports the thumb in a bent position: a) Keeps the metacarpal and phalanges from being displaced by drawing the bones back to a neutral position. When the thumb is in an extended position, the metacarpal acts as a lever and shifts the bones of the hand and wrist out of a neutral alignment creating ulnar deviation. b) Keeps the hand from over pronation (rotating inward). The extended thumb initiates independent pronation of the hand causing the wrist and elbow to move in an opposing direction IE the hand rotates inward and the elbow wants to rotate away from the body. c) Helps hold the bones of the hand on a single plane. This allows the fingers to contract in a linear pattern otherwise the fingers twist as they are contracted. The extended thumb also causes the wrist and hand to hyperextend.
(40) Further, the glove is designed to support the fingers to facilitate the desired generally neutral positioning of the hand relative to the associated forearm. In this regard, it is desirable that the hand be generally aligned with the adjacent forearm.
(41) The hand is generally aligned or coplanar (rather than cocked) with regard to the adjacent surface of the forearm as seen in
(42) It is seen that the plastic support for the thumb retains the thumb such that the thumb, index finger (first finger), and the wrists are placed in a neutral or stable position during use of the glove of this invention. Since the padding provided by the insert's second portionthat is at the crevice of the crease, is smaller at the index and middle fingers than at the third and fourth fingers, contraction of the fingers is less restricted at the little finger and ring fingers (fourth and third fingers) than at index and second fingers. The flexibility decreases from the fourth finger toward the index finger. That is the fourth is less restricted than the index to bending. The thumb support may also be made of flame resistant material for special needs.
(43) While a full glove is the best mode of utilizing this invention, the middle of the fingers of the glove may be cut off without inhibiting the benefits to be gained from the invention as the tips of the fingers of the glove are positioned forward of the insert and forward of the thumb retainer 30 used to support the thumb. Thus fingerless gloves are fully contemplated.
(44) Thus reference is made to
(45) The discussion now turns to
(46) Thumb support 330 which has a side portion 332 in
(47) Thus it is seen that the insert 312, seen in
(48) The fingerless glove 361 of
(49) Here in
(50) If one considers the point of attachment of each finger and the thumb respectively to be the first crease, or bend point, the fingers of glove 360 should be cut off at or about the second or middle crease of each finger and the distal crease of the thumb to be designated fingerless for the purpose of this invention. This will permit a full bending of all of the fingers and the thumb with no impediment. Thus the insert 312 should be located such that no part of the insert extends beyond the cut off edge of each finger and the thumb in glove 311. To ensure long wear, the edge of each finger opening and the edge of the thumb opening should be circularly stitched.
(51) One might inquire as to for whom is this fingerless glove 360 of this second embodiment is intended. Runners and hikers who want to run or jog while holding the patented grips of applicant will have full use of their fingers to hold onto their water bottles. Gardeners will find them ideal for using shovels, spades and other garden tools in a safer mode. Cab drivers, and typists are good candidates for use of this second embodiment, since the fingers need to grip the steering wheel or be able to specifically impact a specific key on a keyboard. The effect that is to be achieved is to stabilize the body while aligning the skeletal frame specifically the fingers, hands, wrists, forearms, shoulders and back while using one's hands in a working position by holding, grasping, turning, rotating etc, namely every motion that the hand and fingers can make. The movement of the arms and the positioning of the hands on the tool or implement affects the position and the stabilization of the body from the waist down. The body reacts to hand and arm actions, laterally elevating your arm with palms down increases the amount of lateral torso and head angulations as opposed to turning the palms up while laterally elevating an arm. Thus the saying, A stable body is a healthy body.
(52) Previously with respect to insert 12 shown in
(53) It has now been found that the desired progressive contraction pattern of the fingers where the little finger is easiest to contract, IE fold over toward the wrist, can be achieved by utilizing a plurality of layers of material, glued, heat welded, sewn or a combination of these procedures, to create a variable resistance pattern from the 5.sup.th finger down to index finger.
(54) The readers attention is directed to
(55) Here also the first portion 319 of the insert 312 extends from about the meta carpophalangeal crease of each finger rearwardly toward the wrist, to the specific inter-digital pad of that particular finger. Each first portion may have an arcuate leading edge, or be linearly cut for a no finger tip glove, if such desired. The construction is the differing point.
(56)
(57) Rather than the groove pattern as shown the several views of
(58) The use of the layering technique to achieve the contraction results desired permits non-flammable materials such as Kevlar to be employed for the benefit of fire fighters, glass makers and fighter pilots.
(59) The thumb support 330 to be employed with the exsert 312 may be similarly constructed to the thumb support 330 and it too can be fashioned from fire resistant material such as carbon fiber, for high heat environment usage. Here in
(60) Of course the exsert 312 can be used on a fingerless glove as well as a fingered one is not specifically depicted.
(61) In
(62) Observations
(63) By using the glove of this invention, the hand is placed into a position wherein the radio-ulna line is in neutral alignment thus avoiding tendinitis and other hand and/or wrist injuries. The contraction pattern of the fingers, when this glove is used, brings about a tighter contraction pattern of the little finger and ring finger to thereby create greater muscular use of the triceps and posterior deltoid muscles, the result of which is to stabilize the pectoral girdle and back, and which keeps the shoulders from internally rotating thereby maintaining spinal alignment.
(64) By a wearer using the gloves of this invention, preferably in pairs, the wearer's biomechanical efficiency is improved due to the retention and support of the thumb in a neutral position and restriction of the contraction of the fingers on a graduated basis.
(65) Any suitable material may be employed for the outer layers of the fingered and fingerless gloves of this invention, such as leather, suede, vinyl, latex rubber, nylon, or fabrics such as cotton, linen, and wool, Kevlar and Nomex. The optional linings may be a knit fabric or other suitable lining material such as lamb's wool or rabbit hair.
(66) It has been observed that the user of the gloves of this invention have their balance affected positively when wearing the gloves of this invention be the gloves, with or without fingers. It is well known that the skeleton is made up primarily of small bones and a few big ones. The key to balance in one's gait and in standing erect is the position of the shoulders. If the shoulders are straight, the spine will retain its desired upright position. When the spine is mis-oriented, one loses their balance.
(67) It has been observed that when a wearer Mr A, has on the gloves and is engaged in an arm curl exercise with another person Mr B, of superior strength, who is not wearing the gloves, that it will be quite difficult for Mr. B to cause the wearer Mr. A to move from a given normal stance. Without the gloves on, Mr. B can move the wearer Mr. A quite easily.
(68) In another exercise, when the wearer has the gloves on, and assumes an elbows by the side palms up stance with the gloves in place, a poke on the chest or push by Mr. B will NOT cause the wearer Mr. A to step back. But with out the gloves and the arms in the exact same position, elbows in, palms up, Mr. B's poke or push can easily cause the wearer to take a step backwards.
(69) If wearer Mr. A without the gloves on, were to take a Phillips or other screwdriver, and practice a few turns on a screw using the right hand, it will be observed that when the wearer works strenuously, the right shoulder becomes arched. This eventually can cause joint discomfort if these rotational movements are carried out for a long period of time. But when the glove is worn on at least the hand using the screwdriver, it is found that the shoulder of the hand with the glove does not rise, thus avoiding potential injury, and assuring proper stance of the wearer.
(70) In essence the wearing of the gloves by workers can help them to maintain a physical alignment that is conducive to the performance of tasks with reduced injuries, and greater ease. Thus the gloves are recommended for package delivery people such as FedEx, post office and UPS workers, construction personnel, and ditch diggers/gardeners among others.
(71) The reader should further understand that the human skeleton is made up mostly of small bones. The wearing of the gloves tends to stabilize the alignment of the back and thus retain these small bones in the correct position relative to each other. The shoulders of the person are the keystone to [proper posture. If on going about certain chores, such as lifting or carrying of an item(s), the shoulders rotate or move, such movement causes the spine to change the position of the basis for your balanceso that you don't fall oversince the body reacts to the orientation of the spine.
(72) For example, if a person carries out rotation of the arm during the use of a manual screwdriver, the shoulder on the right side of the body rises and falls. But where the gloves of this invention are worn, and the same job is performed, the shoulder stays level, such that after many repetitions of screwing in screws, during the assembly of an item, joints on the right side of the body that would have ached without glove wearing, do not ache.
(73) To reiterate what was alluded to above, the gloves of this invention can be made of a variety of materials to suit the job of the wearer. Thus Kevlar fabric, for fire fighters, leather for those persons pulling weeds, or working in thorny plant areas along the nations highways or in fields, cotton for use in clean rooms for semiconductor production, and wool for persons subject to cold temperatures are but a few of the fabrics that can used for the gloves of this invention. The materials suitable for the padding has been discussed supra.
(74) Since certain changes may be made in the described apparatus without departing from the scope of the invention herein involved, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
