SUMMARY OF THE INVENTION
Electronic tablet, cell phones and other electronic hand-held devices are fragile and very expensive to repair or replace. It is quite common that they are subject to being dropped or otherwise damaged by accident or mishandling. There are other devices that present a flat surface for viewing that are hand-held which are difficult to retain in the palm of the hand without a resulting fatigue during prolonged use. As seen in the prior art, other handles are shown which attach to these electronic devices to provide a handle for easier grasp and for additional security.
The present detachable handle is a very simple product. It presents an overall polygonal shaped handle having a flat contact surface attached to the electronic device by a detachable fabric product and an inner handle opening which is contoured to the hand of a user, a padded insert provided in several selected sizes which accompany the product chosen to reduce the handle opening to custom fit the handle opening to the size of the palm of the hand of the user, and the aforementioned detachable product attaching in two mated sections, one attached to the rear surface of the flat object or electronic device, and the other section attached to the outer surface of the palm side of the handle, the two fabric sections attached and detached innumerable times without damage. The handpiece may also be used as an included support and to hang the flat object or electronic device from a hook where a hook aperture is included in the backhand portion of the handle.

DESCRIPTION OF THE PREFERRED EMBODIMENT
A detachable handpiece 10 removably attaching to a flat object 100, including a notebook, electronic tablet or other viewable flat visual display, as shown in FIGS. 1-4 of the drawing figures, promoting an enhanced secure grasp of the flat object 100, the detachable handpiece 10 embodying a polygonal handle 20 defining a rounded end 22, a short non-contact section 23, an angled break 24, a short tapering section 25, a tapered curved end 26, and a long contact section 28, and defining an outer surface 30 and an inner surface 32 defining the palm insert opening 34, the handle forming a continuous and fully connected singular component. As shown in FIGS. 1 and 4, the short non contact section 23 and the long contact section 28 are parallel with one another, with the short tapering section 25 and the long contact section 28 forming an acute angle α.
A plurality of contoured padded inserts 40, one embodiment shown in FIGS. 2, 3A and 3B, of differing depths, the selected contoured padded insert appropriately sized by depth to the user's hand, is attached by an adhesive 45 within the inner surface 32 of the tapered curved end 26 of the handle 20. A detachable two piece connecting fabric material 60, FIGS. 2 and 4, is incorporated within the detachable handpiece 10, with one section of the detachable fabric material attaching by an adhesive 65 to the outer surface 30 of the long contact section 28 with the other section of the detachable fabric material 60 attaching by an adhesive 65 to a rear surface 105 of the flat object 100, FIG. 1. Each section of the detachable fabric material 60 defines a detachable connecting surface 62 and a secure attaching adhesive surface 64, the adhesive surface 64 attaching to the outer surface 30 of the handle 20 or the rear surface 105 of the flat object 100. Preferred examples of a detachable two piece connecting fabric material 60 include VELCRO®, and where a less noisy detachment is desired, the DURALOCK® product by 3M.
Further feature which may also be included within the handle 20 include a formed aperture 36 through the handle 20 on the short non-contact section 23 for hanging the detachable handpiece 10, FIG. 2. There may also be an inward depression 38 in the outer surface 30 of the long contact section 28, FIG. 2, to accommodate the associated section of the detachable two piece connecting fabric material 60. Each padded insert 40, shown in isolation in FIGS. 3A and 3B, defines a concave inner curved portion 42 facing the palm insert opening 34 and partially defining the shape of the palm insert opening 34, an acute angular outer curved portion 44, an upper flat surface portion 46 and a lower flat surface portion 48, the upper and lower flat surface portions 46, 48, increasing uniformly in distance from one another from the outer curved portion 44 to the inner curved portion 42. The adhesive 45 is applied to the upper flat surface portion 46, the lower flat surface portion 48, and the outer curved portion 44, the adhesive 45 securing the padded insert 40 to the inner surface 32 of the tapered curved end 26 of the handle 20.
The best mode dimensions for the handle 20 in the prototype studies indicate the measurements of the handle 20 defining an overall length of approximately five inches, a width of approximately 1.7 inches and an exterior depth of 2 inches and an interior depth between the short non-contact section and long contact section of 1.6 inches. The padded insert 40 would define a width of approximately 1.5 inches with the acute angle between the upper and lower flat surface portions 46, 48 of approximately 25 to 30 degrees. The preferred range of lengths of the lower surface portion would be between 1 inch and 1.7 inches. Custom sizing of the handle 20 and the padded insert 40 would also be available for extra small or extra large hand sizes for users. The preferred choice of material for the handle 20 would be a molded plastic or other lightweight material and the padded insert 40 is preferably compressible foam rubber with an outer rubber coating from prototype testing and from an economically practical standpoint. By using the molded plastic material for the handle 20, a range of colors and pressed or formed logos could be employed in the molds forming the handle.
The most practical use for the detachable handpiece 10 is in application of the handpiece to an electronic tablet or notebook. At present, a tablet or notebook user is required to hold the tablet or notebook in the open palm of the user's hand, right or left. It is difficult to determine just what causes a user to drop the notebook or tablet during use, but it is overwhelmingly common for a tablet or notebook to be dropped. When these devices are dropped, there is seldom any such thing as minimal damage. The screen of the electronic device usually costs as much to replace or repair as the cost of the entire device and success is quite limited on repairs to a dropped electronic device. They never seem to work the same. Thus, the best insurance to prevent damage to these device is to reduce the chance of dropping one of them. The best way to reduce the chance of dropping the device is to provide the device with a means of removably securing a handle to the device that provides the user with a more secure grasp of the tablet or notebook during use, especially one that conforms comfortably to the palm of the hand and actually secures upon the hand is a relatively snug and custom fitted engagement, FIG. 4.
Once the connecting surfaces 62 of the two detachable two piece connecting fabric materials 60 are securely engaged together after being adhesively applied to the respective rear surface 105 of the electronic device 100 and the long contact section 28 of the handle 20, the user slides the four fingers of his hand into the palm insert opening 34 with the thumb oriented in the direction of the tapered curved end 26, placing the selected and now adhesively attached contoured padded insert 40 against the crook of the hand defined by the thumb and forefinger, as shown in FIG. 4 of the drawings. Once applied, the hand can be slightly bent while within the palm insert opening and the user can actually move their hand in any direction without resultant disengagement of the handle 20 and the attached flat object 100. This custom fitted snug engagement is provided both by the size and contour of the handle 20 and the inclusion of the padded inset 40 within the inner surface 32 and tapered curved end 26 as chosen by the user most appropriate suited for the size of the user's hand.
While the detachable handpiece 10 has been particularly shown and described with reference to a preferred embodiment thereof, it will be understood by those skilled in the art that changes in form and detail may be made therein without departing from the spirit and scope of the invention.
