Protective cases and covers for handheld electronic devices, such as various types of MP3 players, video players, cell phones, smart phones, satellite phones, walkie talkies, GPS navigational devices, telematics devices, pagers, monitors, personal data assistants, bar code scanners, as well as various types of computers, including portable computers, laptop computers, handheld computers, ultra-mobile computers, tablet computers, and various hybrid devices that combine two or more of these functions, provide a valuable function in preventing damage to these handheld electronic devices. Various types of protective cases are available that provide a varying amount of protection.
A protective case or cover for an electronic device includes a first hardshell member, a second hardshell member, and a flexible hinge. The electronic device has at least a first portion and a second portion where the second portion is connected to the first portion through a hinging structure such that the second portion articulates relative to the first portion. The first hardshell member of the protective cover removably attaches to the first portion of the electronic device to protect at least one surface of the first portion of the electronic device. The second hardshell member removably attaches to the second portion of the electronic device to protect at least one surface of the second portion of the electronic device. The flexible hinge comprises a flexible material, such as an elastomer, and is attached to the first hardshell member and the second hardshell member such that the flexible hinge of the protective cover aligns with the hinging structure of the electronic device. The flexible hinge of the protective cover flexes to allow the second portion of the electronic device to remain articulable relative to the first portion of the electronic device when the protective cover is installed on the electronic device.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
Many electronic devices are constructed with two pieces that may be joined by hinges or various sliding mechanisms. Examples of such devices may be hand held mobile telephones, portable gaming devices, laptop computer, netbook computers, or other devices.
A protective cover or outer shell for these devices may be constructed with two hard shell components, one for the front portion of the electronic device and one for the rear portion. A silicone or other flexible component may be held by one or both of the hard shell components.
In some embodiments, the flexible component may be held by only one of the hard shell components. In an example of such an embodiment, the flexible component may be installed underneath the rear hard shell component.
In some embodiments, the flexible component may be held or retained by both hard shell components. In an example of such an embodiment, the flexible component may be retained by both hard shell components and the flexible component may have a portion that covers a hinge or other mechanism that may join the two portions of the electronic device.
The flexible component may have pads or other mechanisms that may allow a user to active a button on the electronic device when the cover is installed. Some embodiments may have removable covers for earphone ports or other electrical connectors as well.
In some embodiments, the protective cover may be a removable cover that may be installed and removed by a consumer. In such embodiments, the protective cover may have logos, colors, or other designs that allow a user to personalize their electronic device. In such embodiments, the protective cover may have snaps or other engagement mechanisms that may be easily installed and removed by a consumer.
In other embodiments, the protective cover may not be a consumer installed cover. In such embodiments, the protective cover may be installed by the manufacturer of the electronic device and may be an integral part of the electronic device. In such embodiments, the protective cover may be installed using fasteners, adhesives, snaps, or other mechanisms for which a typical consumer may not have access or ability to install or remove.
In order to provide a cover for both the back portion 110 and the sliding/articulating front portion 112, separate hard plastic shells, such as hard plastic front shell 102 and hard plastic back shell 108, can be utilized. However, plastic shells that attach directly to front and back portions of handheld electronic devices often do not provide a large amount of protection, especially against shocks from impacts. In addition, hard plastic shells may provide openings to operational features of the handheld electronic device that further reduces the protection provided by hard plastic shells.
As illustrated in
The hard plastic front shell 102 may be constructed from thermoplastic polymers and has a hardness generally in the range of 65 to 120 on the Rockwell scale for HDPE, acrylic, PP, PVC, ABS, nylon, 10% GF PC. A narrower range of 105-115 on the Rockwell scale can be used for ABS and PC. These ranges are exemplary only and may vary with specific materials. The thermoplastic polymers can be molded, die cast or otherwise formed to a desired shape. Other materials can also be used for the hard shell, including metals that can be formed or machined to a desired shape.
The hard plastic front shell 102 may attach directly to the sliding/articulating front portion 112 of the sliding/articulating handheld electronic device 104. The hard plastic front shell may allow the sliding/articulating front portion 112 to slide or articulate between an open and closed position without interfering with the sliding/articulating motion provided by a sliding/articulating connector (not shown). The hard plastic front shell 102 may provide impact protection and may have an elevated surface that may protect the sliding/articulating front portion of the sliding/articulating handheld electronic device 104 from impacts.
As also illustrated in
The hard plastic back shell 108 also has a plurality of back shell openings 152, 154, 156, 158, 160 that are aligned with electronic device operational features 174, including buttons and ports, in the sliding/articulating handheld electronic device 104. The electronic device operational features 174 include the operational features illustrated in
As also illustrated in
The flexible silicone layer 106 is molded to fit directly into, and to conform closely to, the hard plastic back shell 108. The flexible silicone layer 106 has a plurality of silicone layer openings 130, 132, 134, 136, 138, 140, 142, 144. Each of these silicone layer openings 130-144 is aligned with back shell hooks 114-128, respectively.
Each of the back shell hooks 114-128 is recessed inwardly from the outer edge of the hard plastic back shell 108 so as to engage the silicone layer openings 130-144. The back shell hooks 114-128 are inserted through the silicone layer openings 130-144 from the outside of the flexible silicone layer 106 and extend inwardly to the interior portion of the flexible silicone layer 106. In this fashion, the back shell hooks 114-128 are disposed inside of the flexible silicone layer 106, adjacent recessed portions, such as recessed portions 182, 184 in flexible silicone layer 106, which allows the back shell hooks 114-128 to engage the back portion 110 of the sliding/articulating handheld electronic device 104.
By inserting the recessed back shell hooks 114-128 through silicone layer openings 130-144, the back shell hooks 114-128 are hidden by the flexible silicone layer 106 and a clean and decorative appearance is provided from the outside of the hard plastic back shell 108. Also, since the back shell hooks 114-128 are recessed inwardly and the flexible silicone layer 106 is recessed outwardly, next to silicone layer openings 130-144, such as recessed portions 182, 184, there is little or no deflection of the flexible silicone layer 106 resulting from insertion of the back shell hooks, which further assists the combination of the hard plastic back shell 108 and the flexible silicone layer 106, to function as a single integrated unit.
Upon assembly, the hard plastic back shell 108 and the flexible silicone layer 106 may be securely married together as a result of the mechanical connection between the recessed back shell hooks 114-128 and the silicone layer openings 130-144, since the back shell hooks 114-128 are inserted through silicone layer openings 130-144. In this manner, the flexible silicone layer 106 appears to be part of the hard plastic back shell 108 and functions as a single integrated unit. As a result, the flexible silicone layer 106 can be made from a soft, flexible material that is more easily capable of absorbing shocks since deformation and movement of the flexible silicone layer 106 away from the hard plastic back shell 108 is substantially restricted.
The back shell openings 152-160 are aligned with various portions of the flexible silicone layer 106, as disclosed in more detail below. As also shown in
For example, as illustrated in
The silicone layer operational features 180 interact with electronic device operational features 174. Specifically, silicone pad 162 interacts with the device button 186, while silicone pads 164, 166 interact with device button 188. Another silicone layer operational feature 180 comprises the silicone plug 172 that is inserted in a jack (not shown) in the back portion 110 of the sliding/articulating handheld electronic device 104.
As also illustrated in
The protective case 800 provides additional protection to the front portion 812 of the handheld electronic device 804 as a result of the use of the combined structure of the hard plastic front shell 802 and front flexible silicone layer 803. Hence, a flexible silicone layer is disposed under both the front plastic hard shell 802 and the hard plastic back shell 808 to provide additional protection to both the front portion 812 and the back portion 810 of the handheld electronic device 804.
As shown in
A silicone cover 922, that is soft and flexible, has a front portion 920 that is disposed in the interior portion of the front surface hard plastic outer cover 902 and a back portion 906 that is disposed in back surface hard plastic outer cover 904. A silicone hinge 908, that connects front and back portions of the silicone layer, is disposed between the front surface hard plastic cover 902 and the back surface hard plastic outer cover 904, and hinges along silicone fold line 910.
In some embodiments, the silicone hinge 908 may be a separate, removable piece that is installed first, then the front cover 902 and back cover 904 may be installed on top of the silicone hinge 908.
In other embodiments, the silicone hinge 908 may be molded to one or both of the front cover 902 and back cover 904. In such an embodiment, the silicone hinge 908 may be overmolded onto the back cover 904 and/or the front cover 902. Some embodiments may use a two-shot molding technique or a separate molding operation to mold the silicone hinge 908 onto one or both of the covers.
As shown in
In other words, the silicone hinge 908 allows access to buttons 958 (
Pads 916 allow activation of buttons 958 on the enclosed handheld electronic device while the protective case 900 is in the closed position. In this manner, the entire side of the enclosed electronic device is protected by the silicone hinge 908, while the pads 916 allow access to the enclosed handheld electronic device.
Mechanical connectors 924 illustrate the manner in which the back surface hard plastic cover 904 attaches to the back portion 956 (
As illustrated in
As disclosed above, the connecting silicone hinge 908 includes pads 916 (
The hard plastic covers 902, 904 protect the handheld electronic device from sharp impacts. The shock of hard impacts is spread along the surface of the hard plastic outer covers 902, 904, and is absorbed by the silicone cover 922. In this manner, the combination of the hard plastic covers 902, 904 and the silicone cover 922 provides both protection and accessibility that has not been available to hinged type of handheld electronic devices, such as flip phones.
Although the embodiment 900 is shown as a handheld electronic device that pivots along a side portion, a silicone hinge can also be provided on a top portion of a protective cover for handheld electronic devices that hinge along a top portion. Further, a silicone hinge can be provided along a bottom portion of the protective cover for handheld electronic devices that hinge along a bottom portion. Of course, the silicone hinge can be employed on either side of the protective cover, depending upon which side the electronic device hinges.
