DETAILED DESCRIPTION
(13) Referring to FIG. 3, one embodiment of an ergonomic tablet holder 20 in accordance with the invention is shown. The tablet holder 20 includes a base 200 that provides the base structure of the tablet holder. Base 200 includes a generally C-shaped channel 202 that provides a space into which a retaining clip 210 may be inserted. Although C-shaped channel 202 has a generally C-shape, other suitable shapes may be used without departing from the invention. Extending from the bottom of C-shaped channel 202 is a base 203 that extends along the back of tablet computer 10 when tablet holder 20 is removably attached to the tablet computer. Base 203 has a sufficient length to provide a surface for a user's fingers to grip, and is also long enough to distribute the force generated when a user holds tablet computer 10 by ergonomic tablet holder 20. As shown, tablet holder 20 is made to be used one-handed, with a user holding the tablet holder with his/her left hand. Furthermore, although the embodiment shown is for a left hand grip, a right hand grip may be used without departing from the invention. As a user grips ergonomic tablet holder 20, the natural one-handed gripping position tends to twist the tablet holder counter-clockwise and off of the tablet computer 10. The length of base 203 counteracts the twisting force described above and exerts frictional force to the back of tablet computer 10, which further secures ergonomic tablet holder 20 to the tablet computer. In the embodiment shown, base 200 is made of injection molded plastic, but any suitable material may be used without departing from the invention.
(14) In the embodiment shown, a handle 206 is attached to and substantially covers the outside of base 200 and provides a soft contoured surface that a user grips when using the tablet holder 20. Handle 206 may be contoured and/or made of any suitable material to provide desired ergonomic performance. As shown, handle 206 has a relatively higher profile section 220 in the center of the length, and relatively low profiles at each side of the higher profile, so that the center high profile section fits into the area of the hand nearest the metacarpophalangeal joint of the user's thumb. On one side of the higher profile section 220 is a thumb depression 222 to fit the user's thumb. At the other end of the high profile section is a low profile section 224 to fit with the user's thenar eminence. In the embodiment shown in FIGS. 3, 5, 6, and 8, handle 206 is made of silicone and is overmolded onto the base 200, which produces an essentially unitary handle base 208. Additionally handle 206 has a plurality of depressions 226 and protrusions 228 to allow a user to more comfortably hold the tablet holder 20. The depressions 226 and protrusions 228 correspond to the space between the user's fingers and the user's fingers themselves, respectively, which provides enhanced contact and between the tablet holder 20 and the user and increases grip comfort. Of course, handle 206 may also be removably attached to base 200 without departing from the invention. Furthermore, handle 206 may be omitted altogether by producing base 200 including the contours normally provided by the handle. Such an embodiment may not benefit from the soft feel of silicone or similar materials as described above, but could be a lower cost or more durable alternative construction.
(15) As shown in FIGS. 4-10, ergonomic tablet holder 20 includes a retaining clip 210 that is removably attached to base 200. As shown, retaining clip 210 is made of a light weight, flexible, somewhat resilient material that will not scratch or mar tablet computer 10 and has a main body 211, a generally C-shaped section 212 at a first end that corresponds to the C-shaped channel 202, and a base retention portion 213 at a second end. Although C-shaped section 212 has a generally C-shape, other suitable shapes may also be used without departing from the invention. C-shaped section 212 forms a recess 214 into which tablet computer 10 may be inserted. In the embodiment shown, C-shaped section 212 has a height that is slightly less than the thickness of tablet computer 10. Retaining clip 210 further includes a bearing surface 216 that contacts the bezel 104. As tablet computer 10 is inserted into recess 214, the C-shaped section 212 is flexible enough to expand slightly, causing the tablet computer to be captured between main body 211 and bearing surface 216. The ergonomic tablet holder 20 is held to the tablet computer 10 substantially by friction. In the embodiment shown, C-shaped channel 202 has a height that is slightly smaller than the height of C-shaped section 212, which aids in retaining retaining clip 210 as it is inserted into C-shaped channel 202, and also causes the clip to exert additional clamping force onto tablet computer 10. Optional base retention portion 213 includes a retention boss 218 that engages clip retention channel 221 on base 200 when retaining clip 210 is inserted into the base to more securely attach the clip to the base. In the embodiment shown, retaining clip 210 may be made of any suitable resilient material including but not limited to spring steel or plastic. Additionally, retaining clip 210 may be coated with anti-slip material, or additives may be included in the material itself, to improve the friction performance of the clip against the metal, plastic, or glass surfaces of tablet computer 10.
(16) As indicated above, the ergonomic tablet holder 20 may be applied to the tablet computer 10 solely by means of friction. Alternatively, the ergonomic tablet holder 20 could be applied to the tablet computer 10 by adhesive means, most preferably a material variously known as suction cup tape or micro suction tape, as such tape is easily removable and easily reapplied, without losing adhesion, or at least the adhesion of which can be readily restored.
(17) Although the invention has been herein described in what is perceived to be the most practical and preferred embodiments, it is to be understood that the invention is not intended to be limited to the specific embodiments set forth above. Rather, it is recognized that modifications may be made by one of skill in the art of the invention without departing from the spirit or intent of the invention and, therefore, the invention is to be taken as including all reasonable equivalents to the subject matter of the appended claims and the description of the invention herein.
