[0046] FIG. 1 is a perspective view of the palm of the user's hand, illustrating the preferred mode of the invention, wherein the eraser is affixed to the side of the hand via fastening means consisting of a finger ring and wrist strap. In alternate modes, the eraser may be affixed to other portions of the hand, and may use alternative fastening means, such as hook and loop, snaps, and/or buckles.

[0047] FIG. 2 is a perspective view of the side of the user's hand, illustrating the ease with which the user may utilize a writing instrument while wearing the hand-mounted eraser.

[0048] FIG. 3 is a perspective view of the side of the user's hand, illustrating the ergonomic form of the eraser portion against the side of the hand, and portion of the eraser that is likely to most engage the board surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0049] Referring to FIG. 1, which is a perspective view of the palm of the user's hand, illustrated is the preferred mode of the hand-mounted eraser (10). Specifically, the hand-mounted eraser for usage upon workboards (10) comprises an elongated eraser (12) attached to a user's hand by a fastening means. In this preferred mode, the fastening means comprises a ring member (18) affixed to the eraser at an interior edge thereof, at a first end (14) of the eraser. As shown, the ring member (18) is a securement means into which the user's smallest finger is inserted. However, it shall be understood that in an alternate mode the ring member (18) may be configured for insertion of a different finger, consistent with the objective of securing the eraser to the hand.

[0050] The fastening means further comprises a strap (20) affixed to a distal end (16) of the eraser. The strap (20) is adapted to be placed around the user's wrist, functioning to secure the eraser (12) in a position generally parallel to the smallest finger and running along the exterior of the side of the hand. The hand-mounted eraser may use one of various fastening means to secure the strap to the user, such as hook and loop assembly, at least one snap, and/or at least one buckle.

[0051] In all instances, the eraser (12) effectively affixes to the hand to allow the user to write upon a workboard in a comfortable manner while actually wearing the eraser. For the purposes of example, FIG. 2 is a perspective view of the side of the user's hand, illustrating the ease with which the user may utilize a writing instrument while wearing the hand-mounted eraser, as no interference with same occurs. As such, the device may be effectively used in connection with chalk boards, black boards, marker boards, dry erase boards, and other flat surfaces with which an eraser is ordinarily used.

[0052] Importantly, the eraser may also be ergonomically contoured to the shape of the hand, adding to user comfort over extended periods of time. For the purposes of example, FIG. 3 is a perspective view of the side of the user's hand, illustrating the ergonomic form of the eraser portion against the side of the hand, and portion of the eraser that is likely to engage the board surface most often. Moreover, the eraser may be of approximately the same width as the user's hand, so as to create a device that does not extend far beyond the hand and is not cumbersome for the user to wear.

[0053] It is important to note that the preferred mode of the device is inherently configured for both right handed and left handed users, such that only one embodiment of the invention need be manufactured to benefit a great quantity of consumers. This will both reduce manufacturing costs and allow several different persons to use the same product, for instance in a classroom setting. In addition, the device may be manufactured in a variety of sizes, such as in small, medium, and large sizes, to provide additional means to comfortably fit users of all ages.

[0054] The device also may be manufactured of at least one of a variety of materials, such as durable plastics and polymers, to provide a generally lightweight product that is inexpensive to manufacture and transport. Moreover, the device may also be designed to be disposable in nature, such as by being constructed of still lighter, less expensive materials, allowing the products to be discarded after an appropriate period of usage.

[0055] The eraser may also be of a size suitable to cover a portion of the back of the user's hand, which will function to allow the eraser to stay on the hand in a firm and secure manner even when the eraser is pressed into the board and moved thereon. The eraser may also be of a size suitable to cover a portion of the palm of the user's hand, for the purposes of additional stability. Furthermore, an extra piece of material may be added to the device to create a stronger, tighter fit of the eraser to the hand. Such will assist in preventing the eraser from rubbing off of the hand when the same is pressed upon the board in question.

[0056] Moreover, the eraser itself may decrease in width from the portion adjacent the user's wrist to the portion adjacent the user's smallest finger, so as to best correspond to the shape and size of the hand. This will provide a secure fit and slightly smaller device for user comfort. Furthermore, the eraser may extend to a length sufficient to cover all or part of the user's smallest finger. This may further function to allow the user to erase relatively small areas of the workboard with greater precision.

[0057] Another important aspect of the invention is that the device functions to prevent markings on the user's hand from being placed on additional objects. For example, the hand-mounted eraser will keep chalk, ink, and the like on the side of the user's hand from being placed on transparencies used in connection with overhead projectors. Clearly, without usage of the hand-mounted eraser, chalk or ink may appear on the side of the user's hand, which would likely interfere with images and information on the transparency when placed on the overhead projector.

[0058] In any mode of production, the device may further include colors and indicia upon the surface thereof, so as to assist in creating a functional product that is also aesthetically pleasing. This will appeal to children, as well as provide an opportunity for corporate advertising and the like, thus adding to the total value of the product.

[0059] In addition, in an enhanced mode, the device may comprise a means to hold a writing instrument thereon, for the purpose of user convenience. For instance, the hand-mounted eraser may comprise a small cylindrical sleeve in which to place a piece of chalk, marker, or similar instrument.

[0060] Finally, it should be noted that in alternate embodiments, the eraser may be affixed to other portions of the hand, if desired. For instance, the invention may be configured such that the eraser is affixed to the back of the user's hand or in an additional location. In such instances, the hand-mounted eraser would be consistent with all concepts and objectives set forth above, and may also comprise all other features and options described herein.

[0061] With regards to all descriptions and graphics, while the invention has been illustrated and described as embodied, it is not intended to be limited to the details shown, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the invention.

[0062] Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can readily adapt it for various applications without omitting features that, from the standpoint of prior art, constitute essential characteristics of the generic or specific aspects of this invention. What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims.
