DISCLOSURE OF INVENTION

The description herein refers to a “glove,” and by that term refers to any apparatus or system that mounts with a user's hand such that the glove moves with the hand and does not require significant exertion by the muscles of the user's hand to maintain the mounting with the glove. Examples of “gloves” as contemplated herein include hand coverings with five fully enclosed fingers, mittens or other hand coverings that accommodate multiple fingers within one portion of the glove, open web structures that extend wholly or partially around a hand, hand coverings that mount with the palm and back of the hand but do not cover any of the fingers, hand coverings that enclose or mount with fewer than all of the fingers, and systems comprising a palm pad and/or fingertip pads mounted with the hand by straps that extend around a finger or the back of the hand.

FIG. 1 is a schematic illustration of an example embodiment of the present invention. A glove 100 is shown in the figure as comprising a flexible material substantially conforming to the shape of a hand; other configurations can also be suitable as discussed above. The glove can comprise various materials, such as cloth or leather. The tips of the glove can comprise a more durable material such as plastic. The glove can comprise adjustable features, such a wrist portion, that facilitate firm engagement with the hand. A patch 101 mounts with the glove 100. A mounting feature 102 mounts with the patch 101. Mounting feature 102 can mount directly with glove 100, as an alternative. The mountings between glove 100 and mounting feature 102 are substantially firm, such that motion of the hand inside the glove is translated to motion of the mounting feature in all three dimensions. Mounting feature 102 can comprise various structures that accommodate removable mounting of a tool such as an abrasive sheet or block. In the figure, mounting feature 102 comprises a slide 104 to accept a tool, with a locking end 105 and a releasable locking end 103. A tool mount 106 comprises features that engage to mounting feature 102. When engaged, the tool mounting is likewise firm, such that motion of the hand in all three dimensions is translated to similar motion of the tool block. The tool block can comprise any of a number of tools, such as sanding or cleaning tools, and including tools such as cups or eating utensils (e.g., for individuals with impaired mobility, muscle control, or coordination). The tool block can also comprise an interface to a power source, such that external power, e.g., electrical or air pressure, can be coupled to the tool block. The mounting feature generally described as on the palm or finger surface; in some applications it can be desirable to have a mounting feature on the back of the hand or glove.

In an example of operation, a tool block has mounted thereon an abrasive sheet. The tool block can comprise a conformable material such as foam to receive the abrasive sheet. The conformable material mounts with a hard backing, which is configured to engage the mounting features. The tool block, with abrasive sheet, is clipped into the mounting feature. The user can then move the hand across a surface, sanding the surface. Repetitive motion of the hand is directly translated to repetitive motion of the tool block and hence repetitive motion of the abrasive sheet. Since the mounting feature firmly retains the tool block, the user does not need to grip the abrasive sheet. Also, since force is transmitted directly to the hand and not indirectly by fingertip gripping of the sheet, larger and more consistent forces can be applied by the user. This increases the efficiency and quality of sanding, and reduces strain on the user's hand. A user can sand longer, better, and without getting weary. When the abrasive sheet becomes worn, or a different grit is desired, or a different type of conformable material is desired (e.g., less flexible, or having a specific shape or contour), the user can simply unclip the tool block from the mounting feature and clip the desired tool block/abrasive into the mounting feature. The user spends minimal time changing tools, leaving more time for productive work.

Snap clips or buttons can form suitable mounting features. Hook and loop fasteners (commonly marketed under the Velcro trademark) can form suitable mounting features. U clips like that shown in the figures can be used in connection with a housing to form suitable mounting features. A slide lock with mating male/female features can form suitable mounting features. Magnetic connections can be used to form suitable mounting features, and can be used to enhance the performance of other mounting features.

FIG. 2 is a schematic illustration of an example tool block. A tool block 200 comprises a mounting feature 202 configured to mount with a glove as described herein. A plurality of scraper features 203 and a plurality of brush features 204 mount with the side of the block opposite the mounting feature. In operation, a user dons a glove according to the present invention, and clips into the glove a tool such as the example in the figure. Motion of the user's hand (to the left in the figure) engages the scrapers, for example to remove ice or paint from a surface. Motion of the user's hand (to the right in the figure) engages the brushes to brush away the material loosened by the first motion. Since the tool block is retained by the clip, applied force can be greater and the tool can be used for longer periods without tiring the muscles of the user's hand.

FIG. 3 provides schematic illustrations of two example tool blocks according to the present invention. Both examples comprise a mounting feature 302 suitable for engagement with a glove as described herein, with a base 303. The base can comprise an elongated hexagonal shape, as shown in the illustration on the right, to facilitate use in tight spaces. The base can be stiff, but with enough flexibility to conform to the intended surface responsive to typical pressure applied by a user's hand. The side of the base 303 opposing the mounting feature 302 in the top example comprises a plurality of stiff bristles 304. For example, the bristles 304 can comprise metal to facilitate cleaning of items such as cooking grills, or can comprise stiff hair or plastic fibers to facilitate cleaning items such as bugs from car windows or grills. A like side of the base 303 in the lower example comprises a plurality of softer protrusions 305. For example, the soft protrusions can comprise fibers suitable for cleaning delicate surfaces such as glass or painted surfaces. Use in connection with a glove as described herein can allow repetitive motion and control of the tool block, with less fatigue and greater force. Also, the glove can provide separation of the user's hand from undesirable environments such as harsh cleaning chemicals or debris from cleaning.

Gloves can be made of a variety of materials, including as examples leather, synthetic leather, polyester, spandex, nylon, neoprene, cotton, latex nitrile, rubber, cow hide, deer skin, goat skin, peccary, silk, wool, cashmere, suede, pig skin, synthetic micro fiber. Gloves can further comprise button snaps, stretch elastic, hook and loop fasteners, or other features to accommodate insertion, retention, and removal of a hand therefrom.

FIG. 4 provides schematic illustrations of two additional example tool blocks according to the present invention. Both examples comprise a mounting feature 402 suitable for engagement with a glove as described herein, with a base 403. The base 403 can be stiff to provide support desirable for working with materials such as concrete or stucco. In the top example, a stiff sponge-like material 404 is mounted with the base 403, facilitating finishing a material such as stucco. In the bottom example, a stiff blade 402, for example of metal, mounts with base 403, facilitating application of a material such as stucco.

FIG. 5 provides schematic illustrations of an example embodiment of the present invention. A glove 500 is configured to mount with a user's hand. A portion 501 of the palm of the glove 500 comprises a surface amenable to removable mounting, such as by pressure-sensitive adhesive, hook and loop fasteners, or vacuum attachment, electrostatic attachment, or magnetic attachment. Portions 502 of one or more fingertips of the glove can have similar mounting features. A block 503 comprises a material with stiffness and compliance suitable for the desired task, for example substantially stiff with local surface compliance for sanding smooth surfaces, or stiff and rigid throughout for imposing a specific contour by sanding. The block can be mounted with the glove at any of, or a plurality of, the mounting features on the glove. As examples, the block can be mounted with the palm to allow the whole hand to be used to apply pressure to and move the block; or the block can be mounted with the fingertips to allow more precise control of the block's motion. The block can itself be abrasive, or can accommodate abrasive materials or sheets to be applied. Various block shapes and configurations can be suitable, depending on the desired work. As examples, the block can have a shape with sharpened corners 504, a half-round shape 505, a rectangular or other shape with a hollow or indentation for securely engaging a finger 506, or a rectangular or other shape with a plurality of hollows or indentations for securely engaging multiple fingers.

In operation, the user can readily switch blocks and abrasive characteristics as the work progresses. The user can switch between block shapes to efficiently sand specific shapes and contours. The user can trade between different grit abrasives by merely detaching one block and attaching a block with the desired grit.

FIG. 6 is a photograph of a glove similar to the example shown in FIG. 5. The attachment features in the example in the photographs comprise hook and loop fasteners.

FIG. 7 is a photograph of a glove similar to the example shown in FIG. 1. The glove is on the right, and has a mounting feature protruding from the palm region. A tool block is on the right, and has a slot structure configured to engage the protrusion of the glove to securely, but removably, mount the tool block to the glove. On the opposite side of the tool block, an abrasive sheet is mounted. When the tool block is mounted with the glove, the abrasive sheet is facing away from the palm of the user, and the user can sand a surface simply by waving the hand over the surface. The user does not need to grasp or pinch the abrasive paper as previously required.

In use, the present invention can relieve stress from the user's fingers and the back of the hand and the wrist and forearm. The present invention can offer advantage in many activities that involve holding an object (such as a tool) for long periods of time, particularly when also involving repetitive motion such as in sanding or scrubbing. In many applications, good practice and regulation can require protective handwear; the addition of the present invention to such applications to such protective handwear can bring productivity, comfort, and health benefits. The present invention can also facilitate increased productivity and self-sufficiency for those suffering from disorders that limit mobility or strength such as arthritis. The present invention can be useful in teaching and maintain proper technique in applications such as auto body finishing and carpentry, and in allowing children and the elderly to be more effective in occupations like those described herein.

Tools can be mounted using blocks (e.g., sanding blocks) made of materials such as plastic, polyethylene terephthalate, high density polyethylene, polyvinyl chloride, low density polyethylene, polypropylene, polystyrene, and tritian. Soft blocks can be from materials such as rigid foam, soft foam, and rubber. Blocks and mounting features can also be made from materials such as plastics, cloth, wood, metal, aluminum, and ceramic.
