Embodiment 100 is an example of a device 102 with a protective cover mounted in a holder. The device 102 may be a cellular telephone, personal digital assistant, camera, portable instrument, barcode scanner, or any other device.
A holder 104 may be mounted to a user's belt, purse, or other object and may allow the device 102 to be installed and removed from the holder 104 quickly and easily. The device 102 is illustrated as having a user installed case 106 that may operate with the holder 104 to secure the device 102 to the holder 104.
In many embodiments, the user installed case 106 and holder 104 may be a supplemental case for a commercial product. The user installed case may be an aftermarket case that a user may install after purchasing an electronic device or other item that may be covered. In many embodiments, such aftermarket cases may be installed and removed by a user.
In many embodiments, the user installed case 106 may operate as a protective cover that may insulate a device from physical damage, including mechanical abrasion such as scratches, as well as damage from dropping or other physical trauma. Some embodiments may provide protection from water, including some embodiments that may be waterproof to some depth of water.
Some embodiments may operate as aesthetic or decorative enhancements to allow a user to personalize their device. In such embodiments, the various components of a protective case may be designed with aesthetic or decorative elements, or may be manufactured with different colors, designs, or textures.
Throughout this specification, the term “user installed case” is used to describe a case or cover that may be separately installed by a consumer or user of a device. Such cases may be supplemental cases to an exterior case of a device as manufactured.
In some embodiments, the components of the user installed case may be designed to be removable. Such embodiments may provide mechanisms for the case components to snap together or otherwise engage each other, as well as a removable flexible component.
In embodiments where a user installed case may be installed in a permanent or semi-permanent fashion, the case components may be assembled using adhesives, ultrasonic welding, snap fits, or other mechanisms. In some embodiments that are installed in a permanent manner, a flexible component may be formed by injection molding the flexible component directly to the rigid component. Some such embodiments may be manufactured using a two-shot molding process.
The user installed case for the device may have a rigid component and a flexible component. The rigid component may be a rigid component that may be designed in two or more pieces in some designs. The rigid component may be manufactured from various injection molded thermoplastics, thermoset plastics, composites, metals, or other materials. The flexible component may be manufactured from a flexible, stretchable material and may be designed to wrap around the rigid component on several sides. Some embodiments may use a molded silicone, for example, which may stretch to allow installation and may wrap around several sides of a device to stay in place.
The device 102 is illustrated as having a touchscreen 108. Examples of such a device may include a cellular telephone, personal digital assistant, or other device. The case may have a rigid component over which a flexible component may be fitted. The case is illustrated as assembled to the device 102 in embodiment 100.
The case may have a flexible case component 110. The flexible component may be a molded silicone or other material that may stretch to fit over the rigid components 112. The rigid components 112 may be illustrated by the component 112 which may protrude through a hole in the flexible case component 110. The component 112 may operate as a latch receiver for the latch 114.
The holder 104 may have a receiver 116 that may engage several sides of the device 102. The receiver 116 may engage a primary side and several additional sides. In the example of embodiment 100, the primary side of the device with respect to the receiver 116 may be the far vertical side of the device 102.
When viewed from the context of projected sides of a device, the receiver 116 may form an open-topped box with a primary side having four edges, with additional sides mating to the primary side along each of the edges. The primary side may be the bottom of the open-topped box.
In some embodiments, the device 102 may have odd-shaped or curved surfaces, which may be considerably more complex than the simple, rectangular shape of the device 102. For the purposes of this specification and claims, a device having an arbitrary shape may be projected using six sided orthographic projection to form “projected sides” of the device. Throughout this specification, the term “sides” of an object refers to orthographic projected sides of the object. An illustrated example may be found in embodiment 200 presented later in this specification.
The receiver 116 may engage five sides of the device 102. The receiver may restrict movement of the device 102 in the up and down and fore and aft directions, where up and down and fore and aft are illustrated as axes 118 and 120. By engaging five sides of the device 102, the receiver 116 may capture the device 102 from moving.
In order to restrict movement in the left right axis 122, the device 102 may be held between the receiver 116 and the latch 114.
The engagement of the receiver 116 to the device 102 in each direction may be sufficient to prevent the device 102 from falling out of the holder 104. For each embodiment, the amount of contact between the receiver 116 and device 102 may be different, depending on the mass of the device 102, the anticipated shock loads experienced by the device 102 when mounted in the holder 104, the ease of installation and removal of the device 102 from the holder 104, and other considerations. Heavier devices and devices subject to more violent loading may have increased engagement between the receiver 116 and the device 102.
In a typical cellular telephone holder, the receiver 116 may provide an edge or lip of 0.050 in, 0.100 in, 0.250 in, or larger, as measured from the primary side. The lip may engage the body of the device 102 and may secure the device 102 from sliding or falling out of the holder 102.
The receiver 116 is illustrated as having a continuous surface that may contact the device 102 along five sides of the device. In some embodiments, the receiver 116 may be discontinuous and may have cutouts, finger grips, or other features formed from voids in the receiver 116. In some such embodiments, the receiver 116 may be formed of two or more fingers that engage one or more sides of the device.
In some embodiments, the receiver 116 may loosely hold the device 102. Such embodiments may have dimensional differences between the receiver 116 and the device 102 of 0.010 in, 0.025 in, 0.050 in, or larger so that the device 102 fits loosely within the receiver 116.
The receiver 116 may be designed so that the device 102 may rotate within the receiver 116 during installation and removal. In such embodiments, one of the sides of the receiver 116 may be angled outward or given additional clearance in the direction of the rotation.
The device 102 is illustrated as being mounted inside a user installed case 106. In some embodiments, the holder 104 may be designed to operate with a user installed case 106 and may engage specific features on the user installed case 106 to mechanically hold the device 102 within the installed case 106. In some such embodiments, the holder 104 may not be capable of holding the device 102 without the device 102 being installed into a user installed case 106.
The holder 104 may have a latch 114 that may have a flexible arm 124 that may engage the rigid case component 112, which may function as a latch receiver. The latch 114 may be designed so that a user may grip the device 102 and rotate the device 102 to disengage the device 102 from the latch 114. In some cases, a thumb grip may be used to lessen or remove the force of the latch 114 against the latch receiver, allowing the device 102 to be removed more easily.
Similarly, the latch 114 may be designed so that the user may place the device 102 in the receiver 116 and rotate the device 102 into the holder 104. In some embodiments, the latch 114 may ride over a portion of the latch receiver and engage a recessed portion of the latch receiver to hold the device 102 in place.
The holder 104 may have a back 126 that may provide a connection for the latch 114. The back 126 may also provide a connection for a belt clip 128 or other mounting mechanism. The belt clip 128 is illustrated as a mechanism by which the holder 104 may be mounted to a person's body. In other embodiments, the back 126 may be attached to another mounting device, such as a tripod, suction cup, or other mechanism. One example of another mounting mechanism may be an articulated mechanism for mounting the holder 104 to the windshield or dashboard of an automobile.
The holder 104 may be oriented in any position and may still hold the device 102. In some embodiments, the belt clip or other mounting mechanism may have an axle on which the back 126 may rotate. Such an embodiment may allow a user to orient the device as shown in the embodiment 100, or the user may rotate the holder 104 90, 180, or 270 degrees.
In some embodiments, a detent or spring engagement mechanism may hold the rotation of the belt clip 128 or other mounting mechanism at certain positions. In a typical embodiment, the rotation may have detented position every 90 degrees or every 45 degrees. In other embodiments, the back 126 may be free spinning in relationship to the belt clip 128.
Embodiment 200 illustrates six orthographic projected sides of the device 102. The orthographic projected sides are used in this specification and claims to describe portions of a device 102 in relationship to a holder, among other reasons.
Orthographic projection is a technique where an object may be projected against planes oriented at right angles to each other. Using such a technique, a ‘side’ of an object of arbitrary shape may be described, even if the object has a ‘side’ that is complex, spherical, or has another shape.
In embodiment 200, the device 102 is shown with a front projected side 202 and a rear projected side 204. A top projected side 206 and bottom projected side 208 are also illustrated, along with a left projected side 210 and right projected side 212.
Using the terminology of embodiment 200, the receiver 116 of embodiment 100 may be said to have a primary side adjacent to the left projected side 210 of device 102. The additional sides that receiver 116 may contact may be said to be the front projected side 202, the rear projected side 204, the top projected side 206, and the bottom projected side 208. The latch 114 may engage a portion of the right projected side 212.
The labeling of top, bottom, left, right, front, and back is arbitrary and not meant to convey any meaning other than to differentiate one projected view from another.
The device 102 is illustrated as being mounted in a user installed case 106, which is assembled into a holder 104 and held by the latch 114.
The receiver 116 is illustrated as engaging the left hand side of the device 102 and surrounding the left hand side of the device 102 with a primary side and four additional sides. Of the four additional sides, the front side 130, top side 132, and bottom side 134 are viewable.
The holder 404 may have a receiver 406 that may engage one side of the device 402. The receiver 406 may have a primary side 408, as well as sides 410, 412, and 414, plus a side defined by the back 424. The receiver 406 may engage a side of the device 402 and prevent relative movement between the device 402 and holder 404.
The holder 404 may have a latch 416 that may provide some spring force by a bending beam spring design. The bending beam spring may be defined by the grooves 418 and 420. The latch 416 may have a ball 422 that may engage the device 402.
The device 402 may have a user installed case 426. A latch receiver 428 may have an indent 430 that may engage the ball 422 of the latch 416.
Many devices may have touchscreens, such as the touchscreen 432. When installed in the holder 404, the device 402 may be oriented with the touchscreen 432 facing out or away from the back 424. In such an orientation, the touchscreen may be visible when the device 402 is installed in the holder 404. In another orientation, the device 402 may be installed in the holder 404 with the touchscreen 432 facing the back 424. In such an orientation, the touchscreen 432 may be protected from damage when mounted in the holder 404.
The elements of embodiment 500 are the same elements as embodiment 400.
The holder 404 is illustrated with a receiver 406 that may capture one side of the device 402 along a primary side, then capture the device 402 with sides 410, 412, 414, and the back 424. While the device 402 engages the receiver 406, the device 402 may be rotated such that the latch 416 and specifically the ball 422 may engage the latch receiver 428 and the indent 430.
The device 402 is shown as captured in the holder 404 with one side captured by the receiver 404 and another side captured by the latch 416. The latch 416 is shown engaging the latch receiver 404.
The orientation of embodiment 600 illustrates an orientation where the touchscreen 432 is shown facing outward, away from the back 424. The device 402 is also illustrated as having the top end 426 of the device at the top of the illustration.
When the device 402 or user installed case 426 are outfitted with latch receivers on two opposing sides, the device 402 may be installed with the top end 426 facing towards the top of the figure as shown, or with the top end 426 oriented toward the bottom of the figure. In such an orientation, the latch 416 may engage a second latch receiver.
Embodiment 700 is similar to embodiment 600, but with the device 402 oriented with the touchscreen facing the back 424.
The device 402 is shown engaged and captured by the receiver 406 of the holder 402, and with the latch 416 engaged with the latch receiver 428. The device 402 is shown with a user installed case 426.
The device 402 is oriented with the top end 436 of the device oriented upwards and with the rear side 434 of the device facing outward. The orientation of embodiment 700 is an orientation in which the touchscreen of the device 402 may be protected from damage.
Embodiment 800 is similar to embodiments 600 and 700, but with the device 402 oriented with the top end of the device 402 downward.
The device 402 is shown engaged and captured by the receiver 406 of the holder 402, and with the latch 416 engaged with the latch receiver 428. The device 402 is shown with a user installed case 426.
The device 402 is oriented with the top end 426 of the device oriented downwards and with the rear side 434 of the device facing outwards or away from the back 424. The orientation of embodiment 800 is a second orientation in which the touchscreen of the device 402 may be protected from damage.
The design of the latch receivers 428 and holder 404 may use a single latch 416 that may engage two different latch receivers 428 depending on how the device 402 is oriented in the holder 404. The latch receivers 428 may be positioned at the midpoint between the top and bottom of the device 402 so that the device 402 may be oriented with the top or bottom end facing upwards, and with the touchscreen 432 facing in or out.
In some embodiments, the latch 416 and corresponding latch receivers may be positioned so that the device 402 may be oriented in two possible orientations. Such a design may be accomplished by positioning the latch and latch receiver in another location not along the midpoint between the top and bottom of the device 402, for example.
When the device 402 may be oriented in multiple orientations with respect to the holder 404, a user may be given different choices during use of the holder 402. For example, a left handed person may wish to mount the holder 404 on the left side of the user's body while a right handed person may wish to mount the holder on the right side of the user's body. In both uses, the users may wish to orient the device with the top of the device facing forward with respect to the user's body. Each orientation may be opposite of the other, and may engage different latch receivers mounted to the device.
In some embodiments, the latch receivers may be molded or formed into the device itself. In other embodiments, the latch receives may be molded or formed into the user installed case. When the latch receivers are part of the device, the user installed case may have a cutout or hole through which the latch receivers may protrude.
In other designs, two or more latches may be disposed along the same side as the latch 416. Such designs may provide additional holding or securing force to prevent the device 402 from being dislodged from the holder 404.
The holder 904 has a receiver 906 that may capture and engage the smaller side of the device 902. This is in contrast to embodiment 400 where the receiver 406 may engage the longer side of the device 402.
The receiver 906 may have a primary side 906, as well as additional sides 910, 912, and 914 in addition the back 916 to capture the device 902.
In contrast to the embodiment 400, the holder 904 may have two latches 918 and 920 disposed to engage sides of the device 902. The latches 918 and 920 are oriented to engage two sides of the device 902 that are perpendicular to the primary side 908. In embodiment 400, the latch 416 may be oriented to engage a side of the device 402 that is parallel to and opposite the primary side 408.
The latch 918 may have an arm 922 which may flex, along with a ball 924 which may engage a latch receiver. Correspondingly, the latch 920 may have an arm 926 along with a ball 928, which may engage the latch receiver 930 and indent 932.
The device 902 may also have a user installed case 934 which may have the latch receiver 930 formed into the case. In some embodiments, the device 902 may include the latch receivers 930 molded or formed into the device 902.
The device 902 may have a touchscreen 936. The device 902 may be inserted into the holder 904 such that the touchscreen 936 is oriented facing the back 916 or facing away from the back 916.
The device 902 is shown engaged into the receiver 906 of the holder 904. The device 902 with the user installed case 934 may be rotated counterclockwise to engage the latch 920 with the latch receiver 930. The latch 920 may have a ball feature that may engage the indent 932. During the installation process, the arm 926 may flex to engage the indent 932.
The bottom end of the device 902 may be captured by the receiver 906, which may prevent the device 902 from moving downwards, left or right, or frontwards or backwards from the perspective of the device 902. The arms 918 and 926 may capture the device 902 and prevent the device 902 from moving upwards, as well as rotating out of the holder 904.
The device 902 may be oriented so that the top end 940 of the device 902 is upwards. Other orientations may allow the device 902 to be oriented upside down, as well as orienting the touchscreen 936 facing towards the back where the touchscreen 936 may be protected.
The device 902 may be fully captured by the holder 904, where the bottom end of the device 902 may be captured by the holder 906 and the arms 918 and 926 may engage the latch receivers 930 and 938, respectively.
The orientation of the device 902 in the holder 904 may similar to that of embodiment 1100, but with the touchscreen of the device 902 facing the back. In the orientation of embodiment 1200, the touchscreen of the device 902 may be protected from damage.
From the view of embodiment 1200, the receiver 906 may engage the device 902 with a minimum of engagement between the various sides of the receiver 906 and the projected sides of the device 902. In some embodiments, the amount of engagement may be 0.050 in, 0.100 in, 0.250 in, or greater. In some embodiments, the engagement may be less than 0.050 in.
The holder 904 may be oriented in any direction while keeping the device 902 captured and held in the holder 904 by virtue of the latch receivers engaging mechanical features of the arms. In embodiment 900, such features were illustrated as spherical features on the arms engaging spherical detents in the latch receivers. Other embodiments may use other mechanical engagements to lock or secure the device 902 into the holder 904.
