BACKGROUND OF THE INVENTION

The present invention relates to protective gloves in general and to finger and thumb protective devices in particular.
Perhaps the most valuable and yet vulnerable part of the human body, aside from our eyes, with respect to performing in the modern workplace are our fingers and thumbs. The fingers and thumbs are not only of high utility in performing dexterous manual activities but also exquisitely sensitive with respect to touch and pain. While gloves generally protect the hands and fingers from dirt and chemical or biological contamination, from abrasion, and from laceration, they are limited in the ability to protect against striking blows such as result from hammer impacts, or to protect against puncture wounds from driven tools such as chisels and punches. Further, the index finger and thumb are often used to position small fasteners such as nails, screws, and bolts. In the case of nails or other tools e.g., punches and chisels, which are struck with a hammer, there is a danger that the hammer blow may partially or completely fail to engage the nail or tool resulting in a direct or glancing blow to these most sensitive of appendages. Various coverings for protecting the fingers have been developed. The thimble is perhaps the most well-known and perhaps oldest digit protector which is used during sewing to prevent a needle when pressed against fabric or leather from inadvertently piercing the finger which supports the fabric against the pressure necessary to force the needle through the fabric or leather. It is also known to incorporate magnets in the fingers of a glove to attract small magnetic objects such as nails, screws, and bolts to the glove to in-part compensate for the loss of dexterity which normally accompanies the use of work gloves.
What is needed is a system of protective covers which fit over the fingers and thumb of a hand wearing a glove, which are readily donned and doffed as the work task changes and which protective covers also function to provide dexterous positioning of objects such as nails and screws.

SUMMARY OF THE INVENTION

The glove and digit protective system of this invention has a glove with pockets at the distal ends of one or more of the glove digits (fingers or thumb) particularly the index finger and the thumb, into which a high-intensity magnet may be positioned and yet relatively easily extracted. It is advantageous, if not strictly necessary, that the magnets be removable so that the same glove can be used where ferromagnetic particles are being generated without attracting and retaining such particles. The glove with the magnets retained within the pockets interfaces with and retains a somewhat enlarged thimble-like protective cover for one or more of the fingers or thumb. The protective cover also incorporates a ferromagnetic portion which may also be a permanent magnet suitabley arranged as to polarity to attach the protective cover to the magnet held in a pocket of a glove digit. The digit protective cover generally covers one or more fingers or a thumb to the first finger joint i.e., extending over the distal phalanx, such that the mobility of the first joint is not substantially impaired. The protective covers are fabricated of a high impact-resistant material such as ABS plastic or other fiber or non-fiber reinforced plastic. The glove may be of leather or a stretch fabric with the pocket opposite the fingernail. For handling small items the protective cover may have an extension which may include a pivotal extension which incorporates a magnet for positioning small objects such as brad type nails, small screws or nuts. When used with a punch or chisel where heavy blows are struck near the fingertips a nonferrous metal plate e.g., nonmagnetic stainless steel or high-strength material such as a carbon-fiber-reinforced composite which is wider than the digit to be protected can be inserted or made integral with the digit protective cover. Where heavy blows are to be to protected against, the digit protective cover may extend at least partly to cover the first joint and even to cover some or all of the middle phalanx. The protective covers may have an articulating extension which also includes a magnet for positioning small objects, or an extension with a layer of pressure-sensitive adhesive.
The protective cover can incorporate a ratchet mechanism for driving rotatably driven fasteners such as screws in which an anti-rotation handle extends away from the ratchet mechanism so as to be gripped by the hand to which the protective cover is attached.
It is an object of the present invention to provide protection to one or more of the distal phalanges of at least one hand covered by a glove.
It is another object of the present invention to provide a digit protective cover which incorporates a permanent magnet which connects the digit protective cover to at least one of the digits of a glove having corresponding magnets localized on said digits.
It is a further object of the present invention to provide a digit protective cover releasably mounted to a glove which can withstand heavy blows.
It is a yet further object of the present invention to provide a digit protective cover with an articulated extension mounted to a glove.
It is yet another object of the present invention to provide a digit protective cover with or without an extension, and a sticky pad on the digit protective cover or the extension for holding nonmagnetic parts.
It is a yet further object of the present invention to provide a digit protective cover incorporating a ratchet mechanism for driving rotatably driven fasteners such as screws.
Further objects, features and advantages of the invention will be apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring more particularly to FIGS. 1-10 wherein like numbers refer to similar parts, a digit protective cover 20 incorporating a first magnet 22, is shown in FIG. 1 positioned above a finger 24 covered by a portion of a glove 26 which covers the finger. The digit protective cover 20 generally covers a finger or thumb to the first joint 25, i.e., extending over the distal phalanx 27, such that the mobility of the first joint is not substantially impaired. The protective cover 20 is generally constructed of plastic such as ABS, although other plastics which may be fiber reinforced can also be used. The glove 26 has a pocket 28 in which a second magnet 30 is removably positioned. The magnet 30 in the pocket 28 is positioned opposite the fingernail 32 and adjacent the finger's distal phalanx pad 34. The cover 20 is positioned such that the first magnet 22 is substantially in alignment with and adjacent to the second magnet 30 in the pocket 28 of the glove 26. The pocket 28 is attached to the glove by stitching or glue on all sides except for the opening 29 where the second magnet 30 is inserted and removed from the pocket 28.
The magnets 22, 30 are preferably of the high-strength rare earth type, e.g., neodymium magnets, comprised of mostly neodymium, iron and boron. The first and second magnets 22, 30 are typically about ⅜ inches in diameter and 1/16 to ⅛ inches in thickness. A nail 36 is shown magnetically held by the first magnet 22 in FIG. 1. The nail 36 so positioned may be tapped with a hammer into a substrate to positioning the nail, at which time the finger 24 with the attached protective cover 20 can be withdrawn, and the nail driven into the substrate.
A second embodiment 120 of the digit protective cover 20 is shown in FIG. 2. The second embodiment is employed in those situations where an object, e.g. a chisel, is held with one or more protective covers 120 which will remain in contact with the protective covers while being struck with vigorous blows of a hammer. Therefore the protective cover 120 is designed to protect the digits 24 from a missed or glancing hammer blow which engages the protective cover positioned over the finger. For this reason the protective cover 120 extends beyond the first joint 25 i.e., extending to at least partly cover the first joint 25 and even to cover some or all of the middle phalanx 31.
To further protect the digit 24 overlain by the protective cover 120 against a heavy hammer blow, a support plate 138 is incorporated into the protective cover. The support plate 138 as shown in FIG. 2 will preferably be located and mounted to a portion 139 of the protective cover 120 which is opposite the digit phalanx pad 34. As shown in FIG. 3, where the glove 26 is shown partly cutaway, the support plate 138 is wider than the finger 24 so that the support plate will protect the finger from a hammer blow coming from the direction shown by arrows 140. The support plate will preferably be constructed of a nonferrous metal such as nonmagnetic stainless steel, bronze, aluminum, or other strong tough material such as a fiber reinforced plastic.
To better engage the flat surfaces 142 of a chisel 144 or punch, such as shown in FIG. 7, the protective cover 120 has a flat surface 146 which can be aligned with the flat surface of the chisel. FIG. 7 shows how a gloved hand with protective covers 120 on the index finger and the thumb can be used to position a chisel 144 to be struck by a hammer.
A third embodiment 220 of the protective cover 20 is shown in FIGS. 4 and 5. The protective cover 220 has an articulated extension 250 formed by a first part 252 which extends from a portion 239 of the protective cover 220 which is opposite the nail 32, and a second part 254 which is pivotally mounted to the first part 252 by a pin 256. The first part 252 where it overlaps the second part 254 may have radial complementary ridges and detents (not shown) to provide stepping like ratcheting or may be a simple friction fit. If ridges and detents are used the parts 252, 254 can be arranged to provide 12° steps, or 30 steps for complete rotation. The distal end 258 on the second part 254 incorporates a magnet 260 which may be better used to position a nail 36, or other small part such as a screw or nut. FIG. 5 shows a modification of the third embodiment 220 of the protective cover 20 as shown in FIGS. 4, where an additional axis of rotation is incorporated in the protective cover between the first part 252 and the cover which is perpendicular to an axis defined by the pin 256. The additional axis is formed between the first part 252 and an intermediate part 253 and also incorporates a pin and radial complementary ridges and detents (not shown) to provide stepping like ratcheting or may be a simple friction fit. Finally it should be understood that all rotation axes could avoided as in the embodiment shown in FIG. 6.
A fourth embodiment 320 of the protective cover 20 is shown in FIG. 6. The protective cover 320 has an extension 350 which extends from a portion 339 on the protective cover 320 which is opposite the nail 32 which has a flat surface 362 with a layer of an adhesive thereon, which may be provided, for example, by a pressure sensitive adhesive 364 such as a urethane foam tape with adhesive on both sides. The pressure sensitive adhesive is used for positioning small fasteners 366 such as screws and nails which are not magnetic. The adhesive layer of pressure-sensitive adhesive is of the type which allows removal of an object, so that while the fastener is held in place while it is started, it is readily separated from the cover thereafter.
Visibility may at times be limited when inserting screw fasteners, making fastener insertion difficult. A fifth embodiment 420 of the protective cover 20, shown in
FIGS. 8-10, takes advantage of an ability to confidently point to a particular area where a fastener is to be inserted, to make visibility of the work surface while inserting the fastener less critical. The protective cover 420 has an opening 468 where a digit of the hand is inserted defining a first end 469, and a second end 470 opposite the first end to which is mounted a ratchet mechanism 472 for driving rotatably driven fasteners such as the screw 474 shown in FIG. 10. An anti-rotation handle 476 extends from the second end to prevent rotation of the protective cover 420. The anti-rotation handle 476 extends from the outer perimeter 478 of the protective cover 420 at an angle α of about 10° with respect to the axis 480 about which the ratchet mechanism 472 rotates as shown in FIG. 8. The handle may be fixed as shown in FIG. 9 or can be arranged with a hinge 477 between the handle 476 and the protective cover 420 as shown in FIGS. 8 and 10. The folding of the handle makes the protective cover 420 more compact for easier storage. The protective cover 420 and the ratchet mechanism 472 has the advantage over a conventional screw driver in that when you an operator holds a regular screwdriver, the operator's wrist must be turned to the side to align the screwdriver shaft with the screw. This throws off wrist and forearm alignment and causes the screwdriver shaft to rotate in an arc when the forearm is twisted to rotate the screwdriver. That is why oftentimes the screw tilts to the side and causes the tip of the driver to be jammed into the fingers holding the screw. The finger-held screwdriver of this invention keeps the rotational plane of the screwdriver shaft in line with the forearm giving the operator better control of the screwdriver as well as a better view. The protective cover 420 incorporates a magnet 30 when used with the glove 26, holding it to the hand to prevent it from falling off if the anti rotation handle is not held. On the other hand, the protective cover 420 and ratchet mechanism 472 can be without a magnet 30 and then the glove will be optional.
It will be observed that the various embodiments of the digit protective cover of this invention may be supplied to a craftsman as a kit, and each may readily be exchanged to work with the same glove to provide protection during various activities. The magnets on the protective covers readily position and connect the covers to the glove, yet are speedily put in place and removed. Digit protective covers which incorporate a support plate 138 or are simply made stronger to take a glancing or direct hit of a hammer may be marked with indicia such as by being marked by a different color, e.g., red to indicate the cover of greater strength.
It should be understood that, with respect to the protective cover 120, if the cover is of sufficient strength it may not be necessary to have a support plate 138 incorporated therein.
It is understood that the invention is not limited to the particular construction and arrangement of parts herein illustrated and described, but embraces all such modified forms thereof as come within the scope of the following claims.
