The present invention discloses a mobile device retention unit 10 comprising a mounting bracket 20 and a retention unit 21. The mounting bracket 20 will generally have a ‘C’ shape having a lower arm 22 and an elongated upper arm 23. The gap 24 formed between the lower and upper arms 22, 23 of the mounting bracket 20 will be designed to fit onto a desk, and attached using a mounting means 25. In the preferred embodiment, the mounting means 25 comprises a lower magnet 26 in the lower arm 22 and an upper magnet 27 placed within the desk of opposing polarity. Other methods of attachment can include, but are not limited to, using friction or suction between the mounting bracket 20 and desk and using a magnet to attach the mounting bracket 20 to a table leg. The upper arm 23 further comprises an adjustable means for retaining the retention unit 21 and a series of grooves 28 for adjusting the height and angle of the retention unit 21.
The retention unit 21 comprises a hollow wooden rectangular prism with a generally rectangular base 31, without a top or front panel. Two mounting drawers 32, 33 are adapted to represent the top and front panels, each mounting drawer 32, 33 comprising two panels 34 connected in an L shape. The first mounting drawer 32 will slide into position to create the front face of the closed retention unit 21. The front panel 34 of the first mounting panel 32 will be parallel to and the same size as the back panel 36 of the retention unit 21. The top panel 37 of the mounting drawer 32 will span the full width of the retention unit 21, but only half of the depth. A means of securing a mobile device will be included on the first mounting drawer 32. In the preferred embodiment, the means of securing a mobile device include magnets placed on the back of the mounting panel 34 in the same polarity arrangement.
A second mounting drawer 33 comprises the same width and height as the first mounting drawer 32. The first and second mounting drawers 32, 33 are capable of sliding in and out of the retention unit 21 from the open side 38. The mounting drawers 32, 33 can be removed from the device 10 and used within the grooves 28 for an adjustable angle. Alternatively, when placed within the retention unit 21, the device 10 will resemble a closed box. The front side 35 of the second mounting drawer 33 will have an erasable writing surface 39 for dry-erase or similar markers. The grooves 28 in the mounting bracket 21 will allow for the interchangeability of the drawers 32, 33.
In the preferred embodiment, the mounting bracket 21 will be 4 inches tall, 3 inches wide, with the upper arm 23 being 6 inches deep and lower arm 22 being 3 inches deep, although other suitable sizes may be used. The arms 22, 23 will be made of a rigid and durable material capable of resisting impact and maintaining form, such as wood, ABS plastic, metal, or an alloy. The retention unit 21 in its closed form will be 10 inches tall, 9 inches wide, and 3 inches deep, although alternative sizes may be used to conform to different mobile devices. The drawers 32, 33 will each have top panels 37 being 1.5 inches deep and 9 inches wide and front panels 34 being 10 inches tall, 9 inches wide. Except for the front panel 35 of the second mounting drawer 34, all panels 34 will be made of a durable and rigid material similar to that of the arms 22, 23 of the mounting bracket 20. In an alternative embodiment, sheet metal is used as the preferred material. In yet a further alternative embodiment, no magnets 26, 27 are used to retain the device. The front side 35 of the second mounting drawer 33 will have the inward facing side 40 made of this material, and the outward side 41 made of a dry-erase friendly material, such as a white-board 39.
The mounting bracket 20 comprises a plurality of grooves 28 on the upper arm 23, one nearer to the open front end 29, and one at the closed back end 30. The grooves 28 in the front 29 will be designed to comfortably fit the back edge of the top panel 34 of either mounting drawer 32, 33. When the second drawer 33 is inserted, this allows for the whiteboard surface 39 to lie at a minimal angle for writing on the desk. The back grooves 30 will be designed to fit and support the bottom base 31 of the open retention unit 21. This allows for the mounting bracket 20 to hold the retention unit 21 as a typical HUD for the mobile device. In an alternative embodiment, the grooves 28 are replaced with an alternative means of attachment which allow for easy adjusting the angle.
In an alternative embodiment, the mounting bracket 20 will be replaced by a mounting stand 51, which consists of a ground unit 52 and an elongated shaft 53 with a mounting tip 54. The ground unit 52 will be a heavy, short, and solid base to provide support for the elongated shaft 53 and attached retention unit 21. The elongated shaft 53 will be made of a sturdy yet flexible material with its proximal end 55 fixed to the top of the center of the ground unit 52 and its distal end 56 fixed to the rear of the retention unit 21.
In the above alternative embodiment, the ground unit 52 of the mounting stand 51 will be 8 inches wide, 2 inches tall, 12 inches deep, and be made of a solid wood or metal material. The elongated shaft 53 will be 4 feet long and 2 inches in diameter, and made of a flexible, yet sturdy, wire metal. The mounting tip 54 will directly latch onto the bottom base 31 of the retention unit 21, or in alternate embodiments, to the back of the retention unit 21, and be made of the same material as the retention unit 21.
In a further alternative embodiment, the retention unit 21 can be replaced by an acoustic retention unit 61. The acoustic retention unit 61 is similar to the original retention unit 21, with a few differences. The acoustic mounting drawer 62 will not have magnets to attach the mobile device to, but rather have carefully positioned acoustic apertures 64 to accommodate sound reverberations. The second mounting drawer will be excluded entirely, and replaced by a smaller locking panel 63 which descends from the top 65 of the acoustic retention unit 61 to mount and lock the mobile device. Centered on the front face 66 of the locking panel 63 will be a knob 67 for easily locking a mobile device in position. On the bottom panel 68 of the acoustic retention unit 61, a series of auxiliary apertures 69 are positioned to allow power and auxiliary wires to engage with the mobile device. The top of the acoustic retention unit 61 will be hinged to the back panel of the acoustic retention unit 61, wherein the top will open, permitting the mobile device to slide within the acoustic retention unit 61 and be secured by the locking panel 63. The acoustic apertures can also be applied to the first embodiment.
The grooves for the original mounting drawer 22, 23 will be absent, leaving only the inner drawer grooves 70, which will be the default location for the acoustic mounting drawer 62. The locking panel 63 will slide down from the open top of the retention unit along the front face 66 of the acoustic retention unit 61 and come to rest on the top of the mobile device. The locking panel 63 will span the full width of the front panel of the acoustic retention unit 61, having a 1 inch height and a 0.5 inch depth, and be made of the same materials as the rest of the acoustic retention unit 61. In an alternative embodiment, the locking panel 63 will further comprise a diamond-shaped knob on opposing ends of the panel, such that when the locking panel is forced downward to secure the mobile device in place, the diamond shape of the knobs within the side grooves will secure the device in position. In other words, this rotational event will cause the device to lock in a secure position, preventing it to shake loose, even when upside-down. Alternatively, the drawer grooves 70 will seat the mobile device (with no mounting drawer 62) and the locking panel 63 will secure the mobile device with a knob, using friction.
In yet a further alternative embodiment, the locking panel 63 will comprise a hollow elongated rectangular shaft (FIG. 6) having opposing spring-loaded release handles. The handles are attached to opposing rubber supports, wherein a spring or other compression system provides opposing force, causing each rubber support to protrude from either end of the elongated shaft. To release the rubber supports, the handles will be compressed together, preferably with a thumb and index finger, while the locking panel is adjusted. The elongated shaft will be made from a lightweight, sturdy material, such as aluminum, plastic, or sheet metal. A plurality of magnets may be included in the locking arm for use with attracting the sheet metal layer directly beneath a thin sheet of plastic or wood veneer on the top of the surface for additional security.
