DETAILED DESCRIPTION

The present disclosure relates generally to devices, systems, and methods for supporting an accessory device or electronic device at an ergonomic orientation. In some embodiments, a foldable support positioned on a bottom surface of the accessory device has a flat configuration and a stand configuration. When in the flat configuration, the foldable support is flat against a bottom surface of the accessory device and adds little height to the accessory device. When in the stand configuration, the foldable support supports a body of the accessory device at an angle relative to the surface upon which the accessory device rests. The foldable support may provide a more comfortable and familiar ergonomic position for a user to provide inputs to the accessory device.

In some embodiments, a wireless keyboard is nested between an upper portion and a lower portion of a foldable electronic device, such as a laptop computer. In some embodiments, the accessory device has a foldable support positioned on a bottom surface opposite the keyboard or other input device. The foldable support is connected to the bottom surface of the accessory device at one end of the foldable support, and a second end of the foldable support is movable to fold the foldable support into a stand configuration and lift up a portion of the accessory device.

In some embodiments, the accessory device is in data communication with an electronic device, such as a laptop computer, a tablet computer, a hybrid computer, a smartphone, a smart television, other appliance, an automobile (such as with a navigation system or control system of the automobile), or another electronic device. In some embodiments, a foldable support provides a first coefficient of friction in a flat configuration and a second coefficient of friction in a stand configuration.

FIG. 1 shows a system that includes an accessory device 100 and an electronic device 102 in accordance with some embodiments. As shown in FIG. 1, a user places the accessory device 100 with an input device(s) 104 oriented upward (e.g., toward the user) on a first surface 106 of the electronic device 102 in a docked position. In some embodiments, the input device 104 is a conventional QWERTY keyboard or other alphanumeric keyboard, a number pad, a touch-sensitive surface (i.e., a capacitive or inductive touch-sensitive surface or display) such as trackpad, a scroll wheel, a trackball, a biometric reader, or other input device for providing information to the electronic device 102. The docked position may allow a user to easily transport and store the accessory device 100 in the electronic device. When open in a laptop posture, the electronic device 102 may support the accessory device 100 on the first surface 106.

In some embodiments, a user provides input commands to the accessory device 100 (and to the electronic device 102 via the accessory device 100) on the input device 104. In some embodiments, the accessory device 100 and the electronic device 102 utilize near field communication (NFC) protocol to charge and/or communicate via the coils in the accessory device 100 and the electronic device 102. In some embodiments, the accessory device 100 and the electronic device 102 utilize Qi protocol or other magnetic communication protocols to charge and/or communicate. In some embodiments, the accessory device 100 and the electronic device 102 communicate through other radio frequency communications, such as Bluetooth or WiFi-direct communication protocols.

In some embodiments, the accessory device 100 blocks, obscures, or otherwise inhibits the use of a portion of the electronic device 102 when the accessory device 100 is in the docked position. In some embodiments, the accessory device 100 is usable in an undocked position remote of the first surface 106 of the electronic device 102, as is shown in FIG. 2-1. The user can place the accessory device 100 in the undocked position to continue using the accessory device 100 wirelessly to the electronic device 102 without occupying the first surface 106.

In some embodiments, the accessory device has a fabric covering, e.g., is wrapped in fabric. In some embodiments, the fabric covering includes a foldable support component on the bottom of the accessory device.

Referring now to FIG. 2-1, in some embodiments, the foldable support 208 is affixed to a bottom surface 210 of a body 212 of the accessory device 200. The bottom surface 210 is opposite a top surface 214 that includes one or more input devices (e.g., input device 104 of FIG. 1). The foldable support 208 is fixed to the bottom surface 210 along an anchor segment 216 of the foldable support 208. In some embodiments, the anchor segment 216 is affixed to the bottom surface 210 on substantially all of the surface area of the anchor segment 216. In some embodiments, the anchor segment 216 is affixed to the bottom surface 210 on at least 90% of the surface area of the anchor segment 216. In some embodiments, the anchor segment 216 is affixed to the bottom surface 210 on at least 50% of the surface area of the anchor segment 216. In some embodiments, the foldable support 208 has at least two segments connected to the anchor segment 216 that are foldable along flexible connections or hinges and movable relative to the anchor segment 216. In a flat configuration, all of the segments of the foldable support 208 are positioned against the bottom surface 210 of the accessory device 200.

In some embodiments, the additional segments include at least an angled segment 218 and a support segment 220. In some embodiments, the foldable support 208 further includes a contact segment 222. The segments are movable relative to one another by flexible connections positioned between the segments. In some embodiments, the foldable support 208 includes hinges positioned between the segments. In some embodiments, the foldable support 208 includes flexible material connecting the segments to allow rotation of the segments relative to one another.

In some embodiments, the flexible connections provide little or no rotational resistance and allow the segments to rotate freely between the stand configuration and the flat configuration. In some embodiments, the flexible connections provide less than 100 Newton-millimeters (N-mm) of rotational resistance each. In some embodiments, the flexible connections provide less than 200 Newton-millimeters (N-mm) of rotational resistance each. In some embodiments, it is critical that the flexible connections provide less than 400 Newton-millimeters (N-mm) of rotational resistance each.

By folding the additional segments to wrap toward the anchor segment 216, the foldable support 208 is movable to a stand configuration as shown in FIG. 2-2. In some embodiments, the stand configuration includes the support segment 220 of the foldable support 208 oriented at a support angle 224 to the bottom surface 210 of the accessory device 200. In some embodiments, the foldable support 208 in the stand configuration orients the bottom surface 210 of the accessory device 200 at a stand angle 226 relative to a flat surface 228 upon which the accessory device 200 rests in a range having an upper value, a lower value, or upper and lower values including any of 2°, 4°, 6°, 8°, 10°, 12°, 14°, 15°, or any values therebetween. In some embodiments, the stand angle 226 is greater than 2°. In some embodiments, the stand angle 226 is less than 15°. In some embodiments, the stand angle 226 is between 2° and 15°.

In some embodiments, the stand configuration includes folding the foldable support 208 around at least an anchor axis 230, such that the angled segment 218 moves around the anchor axis 230. In some embodiments, the contact segment 222 is positioned parallel to and contacting the anchor segment 216 of the foldable support 208. The support segment 220 is oriented at a support angle 224 to the bottom surface 210 and/or the anchor segment 216 to provide support to the accessory device 200. In some embodiments, the support angle 224 is in a range having an upper value, a lower value, or upper and lower values including any of 60°, 65°, 70°, 75°, 80°, 85°, 90°, or any values therebetween. In some embodiments, the support angle 224 is greater than 60°. In some embodiments, the support angle 224 is less than 90°. In some embodiments, the support angle 224 is between 60° and 90°. In at least one embodiment, the support angle 224 is between 70° and 85°. As the support angle 224 approaches 90°, the support segment 220 provides more compressive strength and stability to the foldable support 208 in the stand configuration. As the support angle 224 decreases, the foldable support 208 in the stand configuration provides greater longitudinal stability.

In some embodiments, the accessory device 200 and/or the foldable support 208 includes a stand sensor 232 configured to detect when the foldable support 208 is in the stand configuration. In some embodiments, the stand sensor 232 is a Hall Effect sensor that measures the presence of a magnet located in the contact segment 222 and/or the support segment 220 in proximity to the stand sensor 232. When the foldable support 208 is in the stand configuration, a magnetic element positioned in or on the contact segment 222 or support segment 220 may be located proximate the stand sensor 232.

In some embodiments, the stand sensor 232 is a force sensor positioned to measure a force applied by the support segment 220. The force measured by the stand sensor 232 when the foldable support 208 is in the flat configuration will be less than when the foldable support 208 is in the stand configuration. The increase in measured force may indicate the foldable support 208 is in the stand configuration.

In some embodiments, the stand sensor 232 is a contact switch located in a recess of the anchor segment 216. When the foldable support 208 is in the stand configuration, a complementary protrusion in the contact segment 222 and/or the support segment 220 contacts the stand sensor 232 and indicates the foldable support 208 is in the stand configuration.

Referring now to FIG. 3, in some embodiments, a foldable support 308 has four segments. The anchor segment 316 is configured to be affixed to the bottom surface of an accessory device or other electronic device, while the remaining three segments are movable relative to the anchor segment 316. In some embodiments, the contact segment 322 is shorter than the angled segment 318. In some embodiments, the support segment 320 is shorter than the angled segment 318. In some embodiments, both the support segment 320 and the contact segment 322 are shorter than the angled segment 318. In some embodiments, the support segment 320 is shorter than both the angled segment 318 and the contact segment 322. In some embodiments, the support segment 320 is shorter than the contact segment 322, which is, in turn, shorter than the angled segment 318.

In some embodiments, the foldable support includes a series of layers bonded, adhered, welded, or otherwise affixed to one another. FIG. 4 is an exploded view of an embodiment of a foldable support 408 according to the present disclosure. In some embodiments, the layers include flexible layers with stiffeners 434 affixed thereto to define the segments that are movable relative to one another. In some embodiments, the foldable support 408 includes a plurality of rigid panels with flexible or rotatable connections, such as hinges, therebetween.

In some embodiments, the foldable support 408 includes a magnetic element 436 positioned at a movable edge opposite from the anchor segment or anchor axis. The magnetic element 436 provides a magnetic attractive force between the movable edge and the body of the accessory device when in the flat configuration or the stand configuration to retain the foldable device in either configuration.

In some embodiments, the foldable support 408 includes different materials or different textures of the same material on a first surface 438 and an opposite second surface 440 such that a first friction produced by the first surface 438 and a second friction produced by the second surface 440 are different from one another. In some embodiments, a higher friction material or texture is positioned on a first surface 438 that is oriented toward the accessory device in the flat configuration and a lower friction material or texture is positioned on the second surface 440 and oriented away from the accessory device in the flat configuration. When in the flat configuration, the lower coefficient of friction (COF) of the second surface 440 allows the accessory device to slide more easily and without marring the surface upon which the accessory device rests. When the foldable support 408 is in the stand configuration, the first surface 438 is exposed and oriented outward away from the accessory device to provide increased friction and resist movement for typing or other input commands on the accessory device. In some embodiments, the first surface 438 has a coefficient of friction of at least 0.3 on glass (such as cover glass used on an electronic device display). In some embodiments, the second surface 440 has a coefficient of friction of less than 0.2 on glass.

In some embodiments, the first surface 438 includes a polyurethane. In some embodiments, the first surface 438 includes Tetrapolyethelene, silicone, Santoprene, or other materials known in the art for providing non-slip surfaces on electronics.

In some embodiments, the second surface 440 includes a non-woven fabric, such as Alcantara. In some embodiments, the second surface 440 includes a woven fabric, aramid, hard coated glass, steel, aluminum, polycarbonates, Polyethylene terephthalate, polyoxymethylene, or other materials known in the art for providing non-stick or high wear resistance surfaces on electronics.

In some embodiments, the stiffeners 434 or other rigid elements in the foldable support 408 include a fiberglass reinforced epoxy, such as FR-4. In some embodiments, the stiffeners include steel, aluminum, polycarbonates, Polyethylene terephthalate, polyoxymethylene, etc.

In some embodiments, at least part of the foldable support 408 is radio frequency (RF) transparent to allow wireless communication and/or power transmission through the foldable support 408 to and/or from the accessory device. In some embodiments, all of the foldable support 408 is RF transparent to allow wireless communication and/or power transmission through the foldable support 408 to and/or from the accessory device. For example, the layers, stiffeners 434, and adhesives 442 are all RF transparent.

In some embodiments, the foldable support 408 includes at least the angled segment and the support segment. FIGS. 5-1 and 5-2 are side views of an embodiment of a foldable support 508 with only two segments. The angled segment 518 may be affixed to the bottom surface 510 of an accessory device 500 or other electronic device at an anchor axis 530. In some embodiments, the angled segment 518 is affixed at the anchor axis 530 on the bottom surface 510 and offset from the edge 544 of the accessory device 500 or other electronic device. In some embodiments, the anchor axis 530 is located on the bottom surface 510 and at least 5 millimeters (mm) from the edge 544 of the accessory device 500. In some embodiments, the anchor axis 530 is located on the bottom surface 510 and at least 10 mm from the edge 544 of the accessory device 500. In some embodiments, the anchor axis 530 is located on the bottom surface 510 and at least 15 mm from the edge 544 of the accessory device 500.

In some embodiments, the angled segment 518 rotates around the anchor axis 530, and, as shown in FIG. 5-2, the support segment 520 rotates relative to the angled segment 518 around the support axis 546 to position the foldable support 508 in the stand configuration. In some embodiments, the support angle 524 between the support segment and the bottom surface of the accessory device is in a range having an upper value, a lower value, or upper and lower values including any of 60°, 65°, 70°, 75°, 80°, 85°, 90°, or any values therebetween. In some embodiments, the support angle 524 is greater than 60°. In some embodiments, the support angle 524 is less than 90°. In some embodiments, the support angle 524 is between 60° and 90°. In at least one embodiment, the support angle 524 is between 70° and 85°. As the support angle 524 approaches 90°, the support segment 520 provides more compressive strength and stability to the foldable support 508 in the stand configuration. As the support angle 524 decreases, the foldable support 508 in the stand configuration provides greater longitudinal stability.

Referring now to FIG. 6, when a foldable support 608 is in the stand configuration, in some embodiments, the foldable support 608 and/or the accessory device 600 include a retention mechanism 648 to retain the support segment 620 at the support angle 624 relative to the bottom surface 610. In some embodiments, the retention mechanism 648 includes a notch or other recess in the bottom surface that limits the movement of an edge of the support segment 620 relative to the bottom surface 610. In some embodiments, the support segment 620 snaps into a slot or receiver in the bottom surface 610. In some embodiments, the support segment is magnetically attracted to the bottom surface that limits the movement of an edge of the support segment 620 relative to the bottom surface 610. In some embodiments, the bottom surface has a ridge or other protrusion that limits the movement of an edge of the support segment 620 relative to the bottom surface 610.

By folding the additional segments to wrap around toward the anchor segment, the foldable support is movable to a stand configuration. In some embodiments, the stand configuration includes the support segment of the foldable support oriented at an angle to the bottom surface of the accessory device. In some embodiments, the foldable support in the stand configuration orients the bottom surface of the accessory device at a stand angle relative to a flat surface upon which the accessory device rests in a range having an upper value, a lower value, or upper and lower values including any of 2°, 4°, 6°, 8°, 10°, 12°, 14°, 15°, or any values therebetween.

In at least one embodiment, the support angle is between 70° and 85°. As the support angle approaches 90°, the support segment provides more compressive strength and stability to the foldable support in the stand configuration. As the support angle decreases, the foldable support in the stand configuration provides greater longitudinal stability.

The articles “a,” “an,” and “the” are intended to mean that there are one or more of the elements in the preceding descriptions. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements. Additionally, it should be understood that references to “one embodiment” or “an embodiment” of the present disclosure are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features. For example, any element described in relation to an embodiment herein may be combinable with any element of any other embodiment described herein. Numbers, percentages, ratios, or other values stated herein are intended to include that value, and also other values that are “about” or “approximately” the stated value, as would be appreciated by one of ordinary skill in the art encompassed by embodiments of the present disclosure. A stated value should therefore be interpreted broadly enough to encompass values that are at least close enough to the stated value to perform a desired function or achieve a desired result. The stated values include at least the variation to be expected in a suitable manufacturing or production process, and may include values that are within 5%, within 1%, within 0.1%, or within 0.01% of a stated value.

A person having ordinary skill in the art should realize in view of the present disclosure that equivalent constructions do not depart from the spirit and scope of the present disclosure, and that various changes, substitutions, and alterations may be made to embodiments disclosed herein without departing from the spirit and scope of the present disclosure. Equivalent constructions, including functional “means-plus-function” clauses are intended to cover the structures described herein as performing the recited function, including both structural equivalents that operate in the same manner, and equivalent structures that provide the same function. It is the express intention of the applicant not to invoke means-plus-function or other functional claiming for any claim except for those in which the words ‘means for’ appear together with an associated function. Each addition, deletion, and modification to the embodiments that falls within the meaning and scope of the claims is to be embraced by the claims.

It should be understood that any directions or reference frames in the preceding description are merely relative directions or movements. For example, any references to “front” and “back” or “top” and “bottom” or “left” and “right” are merely descriptive of the relative position or movement of the related elements.

The present disclosure may be embodied in other specific forms without departing from its spirit or characteristics. The described embodiments are to be considered as illustrative and not restrictive. The scope of the disclosure is, therefore, indicated by the appended claims rather than by the foregoing description. Changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
