The use of electronic devices such as smart phones is ubiquitous by consumers. Users take smart phones everywhere with them and are constantly on the body of people everywhere. At times, however, it is desirable to mount a smart phone (or another electronic device) in a hands-free holder or other configuration that does not require the user to hold the smart phone. Throughout this disclosure, the term electronic device will be used; however, other devices such as tablets or any other electronic device also may be used with the systems described herein. Although solutions are available, it is desirable to have a holder that can firmly hold a variety of sizes of electronic devices and quickly release the same electronic device.
In one embodiment, a system for holding an electronic device includes a body portion, the body portion having a surface. The system further includes a first gripping plate and a second gripping plate, each of the first and second holding pieces including a holding surface approximately perpendicular to the surface. The system further includes a first and second arm interconnected with the first and second gripping plate such that the first and second arm are rotationally movable and the first and second gripping plate are linearly moveable, the first and second gripping plate spring driven to move together, the first and second gripping plate configured to move apart when the first and second arm are moved together, the first and second gripping plate being complementarily shaped to hold the electronic device. Alternatively, the first gripping plate includes a first bracket, the first bracket attached to the first arm and the second arm. In another alternative, the first and second arm are mounted at a first and second rotation point, respectively, and the first bracket is attached to the first arm at a first radial distance from the first rotation point and to the second arm at a second radial distance from the second rotation point. In one alternative, the first bracket is attached to the first arm and the second arm via a post-in-slot system. In another alternative, the second bracket is attached to the first arm at the second radial distance from the first rotation point and to the second arm the first radial distance from the second rotation point and the second bracket is attached to the first arm and the second arm via a post-in-slot system. Alternatively, second bracket and the first bracket interconnect with the first arm in locations opposite the first rotation point. In another alternative, the first and second arm are interconnected via gearing. Alternatively, the first and second arm are spring-loaded and thereby cause the first and second gripping plate to be spring driven. In another alternative, the first and second bracket, the gearing, and the post in slot system convert the rotational motion of the first and second arms to linear motion in and out of the first and second gripping plate. Alternatively, a magnetic interconnect device is mounted on the body portion. In another alternative, a cylindrical mounting device is mounted on the body portion. Alternatively, the cylindrical mounting device includes a strap and prong attachment mechanism. In another alternative, the cylindrical mounting device includes a flat spring which flexes to allow the cylindrical mounting device to rotate. Alternatively, first and second rotation point are located on a line in-line with a direction of movement of the first and second gripping plates. In another alternative, the first and second rotation point are separated from each other.
In one embodiment, a mounting system for an electronic device includes a gripping area is provided for gripping an electronic device, wherein the gripping area is spring loaded to provide gripping force between a first and a second gripping plate. The mounting system further includes a first and second release lever, configured to release the gripping force of the gripping area when the first and second release lever are pushed together, the first release lever mounted at a first central rotation point and the second lever mounted at a second central rotation point. In one alternative, the first and a second gripping plate move in a plane of movement in and out. Alternatively, the first and second release levers move in a rotational fashion and rotational movement of the first and second release levers is converted to a single plane of movement for the first and a second gripping plates by via gearing between the first and second release levers and a first and second sliding bracket for the first and second gripping plates that are each attached to a first one of the first and second release levers at a first location and a second one of the first and second release levers at a second location. In another alternative, the first location on the first release lever is a first distance from the first central rotation point and the second location of the second release lever is the same first distance from the second central rotation point. Alternatively, the first and second release lever rotate inward the first and second gripping plate release.

Certain terminology is used herein for convenience only and is not to be taken as a limitation on the embodiments of the systems and methods for an adjustable, quick release, positive pressure, electronic device holder with quick release functions (Device Holder). In the drawings, the same reference numbers are employed for designating the same elements throughout the several figures. Herein, the Device Holder is designed for various electronic devices, such as smart phones, tablets, and other electronic devices that typically have a screen oriented towards the user. Although electronic devices of smart phones and tablets are most commonly used with the Device Holder, embodiments may be designed to removably attach to a wide variety of electronic devices or other items that have a back that may rest against the device holder and can generally be held by the clamps closing around the sides of the device or item.
In many embodiments, the Device Holder includes two pivot points. These may be referred to as rotation points as well. The inclusion of two pivot points allows for the Device Holder to include hand levers, whose movement remains within the ergonomic range of a human hand while giving the clamps enough range on the X-axis to accommodate the range of phone widths. Additionally, the Y-axis movement of the top ends of the levers is minimized, which is necessary for the device to maintain a reasonable level of complexity. If the Y-axis movement of the top ends of the levers were increased, then there would be difficulty compensating for this movement, while translating the X-axis movement of the levers to the clamps. This also holds true for the bottom ends of the levers where the clamps (the frames thereof) interconnect with the ends of the levers. In other words, the hand levers of the device need to be positioned so that the handles on their ends are close enough in full open position to allow a human hand to squeeze them together while the clamps can move in the range they need to accommodate all the desired sizes of devices. The inclusion of two pivot points for the hand levers (levers 130, 135) allows for greater linear movement of the clamps (gripping plates 110, 115) for a given Y-axis movement. In some embodiments, the inclusion of two pivots points for the hand levers allows for twice the linear movement of the clamps within a comparable Y-Axis range as compared to a dual lever system with a single pivot point.
By setting the pivot points apart, the rotational motion of the levers may be translated to horizontal movement of the clamps in the range where the rotational movement of the connection points (between the clamps and the lever arms) is predominately in the x-axis direction (the direction of movement of the clamps) while maintaining a reasonable lever arm length. This can be explained by the Cosine function, since the Cosine of an angle equals the x-value of the endpoint on the unit circle. If the horizontal movement of the clamps is considered the x axis, when the levers are positioned at ½ π radians, the Cosine function is 0. From ½ π to either ¼ or ¾ π radians, the majority of x axis movement occurs (the Cosine of ¼ π is approximately 0.7, so from ½ π to ¼ π radians approximately seventy percent of the x-axis movement has already occurred). The levers and clamps in embodiments of the Device Mount are situated to accommodate a smart phone, the smart phone typically having a body width and height that are similar in proportion to the total width and height of the Device Holder. (Practically, users want a mount (such as the Device Mount) that is probably less than twice as wide and less than twice as long as a smart phone, and probably less than 1.5 times as wide and long, therefore being approximately on the same scale. If infinite width a length of the Device Holder and an accompanying infinite length of the lever arms were practically possible, then it would be easy to keep the radial rotation close to ½ π radians.) In terms of the actual plate that the phone rest on, named gripping plate herein in some embodiments, the plate is slightly less than the expected width of the expected smart phone and typically less than the height of the expected smart phone. If the levers were mounted at a single point, in order to accommodate the usual minimum width of a smart phone, the levers would be already rotated close to ¼ π radians (45 degrees) from ½ π of rotation off of the x-axis (in other words, ¼ π radians (45 degrees) off of the y-axis). Here, additional movement of interconnection point of the levers will primarily be in the y-axis direction, since the Cosine of values of from 0 to ¼ π radians and from ¾ π to π radians are generally smaller in terms of absolute x-axis movement. Therefore, by oriented the lever arms apart, the lever arms start in a position close to parallel with the y-axis (a ½ π radian rotation), but still accommodate the minimum expected width of the smart phone. In this case as in many of the embodiments described herein, the rotation of the lever arms will primarily translate to x-axis movement of the clamps from this starting position, maximizing the usefulness of the device and the effectiveness of squeezing the lever arms.
Another feature is the gearing between the two levers. The inclusion of two pivot points enables this gearing in many configurations. The gearing and the two pivot points function to keep the levers and clamps mechanically synchronized. Furthermore, they remove the need for linear guides/tracks for the clamps (which is an advantage because the guides create tolerance and friction issues). Finally, they keep the clamps and device always centered (naturally without having to add other features/stops).
In many embodiments, the clamps stack on top of the lever arms, attaching at the top and bottom. The bottom legs of the clamps stack on top of each other, which allows the clamps to attach to the levers on both sides of the pivot points. These dual attachment points on the levers on each side of the pivot points greatly increase the stability and strength of the clamps.) — Additionally, the levers are about twice the length on the bottom side of the pivot points so the distance traveled at the ends of the levers approximately doubles, compared to the forces required to push on the ends of the levers. In other words, clamp force on the device is about double the force required to squeeze the levers. Additionally, in many embodiments the Device Holder uses a constant force (also called clock springs) springs in the design deliver a relatively flat/constant force curve over to the whole clamping range. The force does increase as they are compressed (but not as much as other types of springs) and this may be desirable since the clamping force is increased on the larger/heavier devices, which need more holding force.
Additionally,
Additionally, backstrap system 910 is visible in an exploded view. This system is designed to wrap around a cylindrical object. This system includes a friction disc 1610, which may be made of a rubberized or other high friction material. Friction disc 1610 interfaces with body 1620 in slot 1660, which is shaped in a complementary fashion. Body 1620 includes prong 1625, which is designed to interface with the holes in rubberized belt portion 1650. Screw 1630 cooperates with threaded insert 1655 in order to hold the assembly of backstrap system 910 together. Screw 1630 actually fits on the other side of strap holder 1645 such that it sandwiches all of the parts. Spring 1635 provides pressure and tension to the backstrap system 910 when assembled, such that the friction of friction disc, the back 770, and body 1620 is sufficient to resist movement. At the same time the spring 1635 may be compressed and the device may be turned in relation to the back 770. Spring 1635 may be a wave disc spring in many embodiments. Backstrap system 910 also includes boss 1640 which assists in the interconnection of the parts. In operation, as shown in
In many embodiments of the device holder, a gripping area is provided for gripping an electronic device. The gripping area is spring loaded to provide gripping force on an object placed between two gripping plates. Two release levers are provided to release the gripping force of the gripping area. The gripping plates move in single plane of movement in and out. The release levers move in a rotational fashion. The device holder is designed to convert the rotational movement of the release levers to a single plane of movement for the gripping plates. This is accomplished via gearing between the arms and a sliding bracket for one of the gripping plates that is attached to a first one of the arms at a first location and a second one of the arms at a second location. The arms have a central rotation point. The first location on the first arm is a first distance from the central rotation point. The second location of the second arm is the same first distance from its central rotation point. When the first and second arms rotate, the gripping plate is pulled in the same direction by the first and second arm as the first and second arm rotate in opposite directions, however the translated single plane movement is in the same direction. At the attachment locations, a post in slot arrangement is used so that the post may slide in the slot in order to compensate the translation of the rotation motion of the arms into planar/linear movement. Additionally, a variety of interconnection mechanisms may be on the back side of the device holder. This includes but is not limited to the magnetic system shown and the cylindrical interconnection system shown, as well as clamps, magnets, Velcro, snap fit systems, pressure fit systems, adhesives, and other fasteners (like screws, bolts, etc.).
