FIG. 1 is a top view illustration of an embodiment 100, showing a folding stand and cover. FIG. 1 is not to scale. Embodiment 100 illustrates an example of a protective case that may be removed from a device, then folded into a stand for the device.
Embodiment 100 illustrates a cover that may protect a device when the device is not in use. A typical electronic device for which the cover may be used may be a tablet or slate computer. Many such devices may have a touchscreen that may occupy a large portion of the body of the device. Some such devices may have one or more additional keys or buttons on the front, sides, or rear of the device. Some devices may also have cameras mounted on the front or back of the device, as well as speakers, microphones, accessory devices, charging receptacles, electronic interface receptacles, or other interface connections.
The devices may include various media readers, such as book readers, as well as game consoles, touch screen interfaces for automation systems, non-touchscreen display devices, or other devices. In many cases, the devices may be predominately flat and thin, although other devices may have curvature or other shapes.
The cover 102 may be attached over the display portion of the device when assembled onto the device in a protective position. Some embodiments may also have a storage position where the cover 102 may be attached over the rear of the device so that the user may use the device while keeping the cover 102 attached to the device.
The cover 102 may be a one piece cover that may be manufactured from several rigid components that are joined by flexible hinges. In a typical manufacturing process, the rigid components may be manufactured first, then overmolded with a flexible material to join the components together. In some instances, the rigid components and flexible material may be manufactured using a two-shot molding process.
The various rigid materials may be manufactured from any suitable material, which may be metal, plastic, or other material. In many embodiments, the rigid components may be molded thermoplastic parts, such as nylon, polystyrene, polycarbonate, polyvinylchloride, polypropylene, acrylonitrile-butadiene-styrene, polyurethane, or other plastics. Some embodiments may use reinforcements, which may be glass fibers, carbon fibers, metal fibers, polyamide fibers, or other reinforcements. Some embodiments may use fillers, such as hollow glass beads, entrapped air, or other filler materials that may reduce the weight of the product. Some embodiments may use weighted fillers, such as ceramic or other fillers that may add weight to the product.
The flexible material may be a thermoplastic polymerized rubber that may be molded onto the rigid components. Other embodiments may use a moldable silicone or other material.
In some embodiments, the cover 102 may be manufactured from a single material. In the flexible areas, the material may be a thin cross section so that the material may flex, and the rigid areas may have a thicker cross section where the material may not flex or not flex as much as the thin areas.
The cover 102 may be constructed from rigid components 104 and 106, which may be joined by a hinge 108. The rigid components 104 and 106 in many embodiments may be the largest portions of the cover 102 and may cover much of a device when the cover 102 may be attached in a protective position.
A stringer 110 and a lock plate 112 may be joined together with a hinge 116. The stringer 110 may be joined to the rigid component 104 with a hinge 114, and the lock plate 112 may be joined to the rigid component 106 with the hinge 118.
When the hinge 108 is folded in one direction and the hinge 116 is folded in the opposite direction, the lock plate 112 may engage the rigid component 106 and provide a stand for displaying and using the device. The lock plate 112 may have a hook 126 that may engage a receiver 128 to lock the stand in a folded position.
The device may be held in place in a protective position by engaging the engagement pockets 120 and 122, as well as the engagement lip 124. In some embodiments, the engagement lip 124 may be a rigid feature and the engagement pockets 120 and 122 may be flexible features. In such embodiments, an electronic device may be slipped into the engagement lip 124 and the engagement pockets 120 and 122 may be folded over the corners of the device. The cover 102 may be removed by the reverse process.
In some embodiments, the engagement pockets 120 and 122 may be rigid features and the engagement lip 124 may also be rigid. In such embodiments, the flexible material forming the main hinge 108 may be stretchable enough to allow a user to stretch the cover 102 to engage the device. In some such embodiments, the cover 102 may attach with a snap onto the device.
In still other embodiments, the engagement lip 124 may be a movable feature that may rotate over the device and snap into place.
The centerline 130 of the main hinge 108 may be offset from the centerline 132 of the cover 102. The offset of the main hinge 108 may create a folding stand that has two different angles to support the device.
Embodiment 100 shows the main hinge centerline 130 as being parallel to the longest side of the cover 102. The longest side of the cover 102 may be considered a horizontal landscape axis. Other embodiments may be oriented such that the main hinge centerline 130 is parallel to the shortest side of the cover 102. The shortest side of the cover 102 may be considered the horizontal portrait axis.
The hinge 118 may have a lock plate hinge centerline 134. The lock plate hinge centerline 134 may be closer to the main hinge centerline 130 than the top edge of the cover 102, as seen in the embodiment 100.
The hinge 116 may have a centerline that is coaxial with the main hinge centerline 130 when the cover 102 is flat. In some embodiments, the hinge 116 may be located parallel to but offset from the main hinge centerline 130.
In many embodiments, the various hinges may be formed so that the hinges naturally bend in a particular direction. In such embodiments, the bend of hinge 116 may be opposite of the main hinge 108.
