DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

(14) The present invention is directed to a kit or assemblage of components designed to provide enhanced comfort and safety for users of laptops, desktop PCs, and other similarly configured electronic devices which require tactile interaction. While primarily designed for use with laptop computers, the assemblage, generally indicated by the numeral 10, may also be used with desktop computers.

(15) As illustrated in FIGS. 1-10, assemblage 10 comprises the following components: two wrist pads 20, 22; two connected thigh pads 50; a rectangular shaped, wrist pad 40 that is hollow for storing items; and a mouse pad 42 upon which the other components are able to be stored. Assemblage 10 enhances comfort by providing components that provide more ergonomic positioning for the user's hands when using a keyboard or mouse; and shield the user's lower body from EMF radiation when the laptop is positioned on a user's thighs.

(16) In FIG. 2, it can be seen that wrist pads are comprised of left section 20 and right section 22, which are adapted for attachment to respective left and right front corners of a laptop 24. In an embodiment, pads 20, 22 are mirror images and marked as right (R) and left (L). In another embodiment, they are identical and interchangeable.

(17) As illustrated in FIGS. 6A and 6B, the wrist pads 20, 22 have a main body 28, 30 with a substantially triangular shape corresponding to the corner placement of the pads 20, 22. Thus, when positioned on the laptop 24, the edges 31, 33 of main body 28, 30 of wrist pads 20, 22 are flush with the corresponding edges of a laptop 24 having a rectangular configuration as is typically the case. The main body 28, 30 of wrist pads 20, 22 is formed of, or includes, radiation shielding material therein. The materials may be of a non-lead shielding material. Non-lead shielding materials are manufactured with additives and binders mixed with attenuating heavy metals that fall into the same category of materials as lead that also absorb or block radiation. These metals may include tin (Sn), antimony (Sb), tungsten (W) bismuth (Bi) or other elements. Of course, any other suitable materials may be used as would be apparent to one of skill in the art. The main body 28, 30 of wrist pads may alternatively be formed of cloth or synthetic material such as polyester, which encloses radiation shielding material.

(18) The upper padded portion 32 (i.e. the curved straps) of the wrist pads 20, 22 is attached to the main body 28, 30 by an elasticated connector or portion 34, which allows for some variation in the size and thickness of the laptop 24. Elasticated portion 34, in another embodiment, is also removeable, adjustable via a Velcro® strip positioned beneath pad 32. Preferably, the elasticated portion 34 further comprises a non-slip outer surface 35 that provides friction to reduce slippage of the wrist pad 20, 22 relative to the laptop 24 regardless of the dimensions of the laptop allowing different configuration of hand sizes and laptop sizes. Thus, the outer surface 35 helps to keep wrist pads 20, 22 in position on the laptop 24 by providing friction material to reduce the possibility of the wrist pads 20, 22 sliding off of the laptop 24.

(19) The upper portion 32 has a resting surface 37 upon which the user may place their wrists, is configured for the positioning of the heel of the user's wrist, and accordingly has an arcuate or curved shape to allow for pivoting the wrist from side to side without upper portion 32 hindering movement of the hand or fingers. That is, the curved shape of upper portion 32 and resting surface 37 corresponds to the arc that a human wrist or wrist pad would follow as the user's hand pivot in Ulnar (e.g. 30 degrees) and Radial (20 degrees) hand divination reducing carpal tunnel micro trauma and inflammation thereof. Also, by raising the position of the heel of the hand, the user's hand is elevated to a more neutral ergonomically sound position versus a 10-20 degrees wrist extension relative to the plane of the laptop's 24 keyboard. To achieve the proper positions of the hand, upper portion 32 is padded, such as with a memory foam, or is formed of a more sturdy material layer with proper ulnar, radial nerve positions carved into it, then with a top layer of padding. In an exemplary embodiment to treat CTS, the curved pad 32 has a thickness of from about 2 millimeters (mm) to about 4 mm for the thumb, forefinger position (e.g. radial nerve); and about 4 mm to about 6 mm for the pinkie finger (e.g. ulnar nerve). The elasticated portion 34 has a thickness of about 1 mm. As illustrated in FIGS. 1A, 1B, 2 and 4, another wrist pad 40 of the assemblage is sized and shaped for positioning on a mouse pad 42, the wrist pad 40 also serving to elevate the user's (right) hand to a more neutral ergonomically sound position versus wrist extension of about 10-30 degrees relative to the plane of the mouse pad. The main wrist pad 40 includes an interior cavity 43 within which small items, such as pens and pencils, may be stored. The cavity 43 may include a closure with a fastening means 44 well known in the art (e.g. a snap fit) to open and close the door 45.

(20) As illustrated in FIGS. 1A, 1B, 5, 7, EMF or RF shielding is also provided by a cooperating pair of lap cushions 50 that are connected by a relatively short elasticated strap 52. The strap 52 serves to allow for some relative movement of the user's legs, as the cushions 52 are sized to rest upon the left and right legs, respectively. The cushions 50 are made of the same material as the wrist pads 20, 22 discussed above, and are relatively flexible for more secure positioning on the user's lap. The cushions 50 may alternatively be used as wrist wrests, providing a larger surface than wrist pads 20, 22. Cushions 50 are preferably used as wrist rests when the assemblage 10 is used with a desktop computer. And/or as illustrated in FIG. 2, lap cushions 50 can be used on a table-top to support a user's forearms, and the corner pads 20, 22 to support their wrists. Regarding FIG. 3, it can be seen that the assemblage 10 may also be used with a keyboard 60 associated with a desktop computer. In this deployment, lap cushions 50 are positioned in front of the keyboard 60 to serve as an ergonomic adjustment to affect hand position as mentioned above.

(21) Storage: referring now particularly to FIGS. 1A and 1B, the assemblage 10 is shown in the storage mode on a mouse pad 42. It can be seen that assemblage 10 components 20, 22, 50, and 40 are sized and shaped to be positioned on the included mouse pad 42, the components geometrically shaped to be in non-overlapping relation with respect to each other, while being contained within the rectangular perimeter of the mouse pad 42. The components may be stored in a space saving manner such that the “footprint” of all of the components 20, 22, 40, 50 does not exceed the surface area of the mouse pad. The mouse pad 42 may be designed with Velcro® strips 56 (e.g. FIG. 1B, horizontal parallel lines) or other fastening means positioned on the mouse pad underside to hold the components 20, 22, 40, and 50 in relative position for compact storage and transport. The components 20, 22, 40, and 50 may further comprise matching, aligned Velcro strips 55 on the underside (e.g. FIG. 1B, dotted lines) to affix to the mouse pads Velcro® strips 55; or the surface material of components 20, 22, 40, and 50 allows for the mouse pads Velcro® strips 55 to attach and detach easily without damaging the material.

(22) Alternatively, mouse pad 42 and components 20, 22, 40, and 50 may be stored in a box, bag or container without damaging them. It should be noted that a key aspect of the invention is that the components 20, 22, 40 and mouse pad 42 are shaped both for function and to be stored in a compact fashion.

(23) Alternative Wrist Pads

(24) A variety of alternative wrist pads are envisioned within the scope of the present invention to allow user adjusting the location of the pads to their comfort level and to properly align the keyboard components. As illustrated in FIG. 8, the right pad 22 or both pads 20, 22 are able to detach one end of the strap (e.g. the top) in order to affix the pad(s) to the laptop surface near the touch pad in alignment with the keys—e.g. right pad is aligned with the keys “J, K, L, etc.”, and the left pad is aligned with the “F, D, E, A” keys. In an embodiment, the main body 28, 30 is still beneath the laptop, and 28, 30 have a thickness of about 1.0 mm to about 1.5 mm to not tilt the computer keyboard. Velcro® strips 55 may be positioned as part of the elastic portion 34 to detach and reattach the strip 32 to the base triangle (e.g. see FIGS. 6A, 6B).

(25) An additional embodiment, extension strip 80 may be used to position the left and/or right strap near the middle of the keyboard, and it may connect to the main body 28, 30; or strip 80 may substitute in lieu of the main bodies (e.g. strip 80 encircles the underside of the laptop edges). Strip 80 is able to connect to cushion 32 by methods well known in the art: e.g. Velcro® strips 55, magnets 70, etc. . . . .

(26) In another embodiment, the wrist straps 32 comprise top cushions without components on the computer underside. For example, FIGS. 9A and 9B are perspective views of a laptop with upper portion curved straps 32 completely detached from a main body 28, 30 and affixed to the laptop surface using 2-way Velcro® strips 55 and/or magnets 70 positioned between the straps 32 and the laptop surface 72 (e.g. see exploded view FIG. 9B). FIG. 10 illustrates how the curved straps 32 continue to provide prevention and/or alleviation from carpal tunnel syndrome (CTS) by allowing the user to move the straps to a position that they can comfortably rest the palm of their wrist's on while keeping their fingers in alignment with the proper typing keys.
