1. Field of the Disclosure
The disclosure relates in general to a kickstand and, more particularly, to a kickstand for a portable electronic device.
2. Background Art
Over the years various kickstands have been marketed for use to support mobile phones and other portable electronic devices. Such conventional kickstands include HTC kickstands, Evo kickstands, 4G phone kickstands, and other types of kickstands. Many of these conventional prior kickstands are flimsy, awkward, and cumbersome, contain too much metal, are heavy, unstable, and/or defective. Furthermore, undesirably many of these conventional kickstands are not part of the mobile phone or other portable electronic device but are part of a separate protective carrying case which encloses or encases the mobile phone or other portable electronic device.
It is, therefore, desirable to provide an improved kickstand for use with mobile phones and other portable electronic devices, which overcomes most, if not all of the preceding disadvantages.
It is also desirable to create a drop-in kickstand mechanism assembly with minimal metallic components to achieve better weight reduction and minimal interference with antenna structures as well as provide functional capability for audio, high audio porting, and user interface with a hall-effect switch and magnet.
An improved kickstand provides a modular multi-purpose kickstand mechanism for use with mobile phones and other portable electronic devices which is effective, efficient and attractive. The lightweight kickstand comprises a drop-in kickstand mechanism assembly that has minimal interference with antenna structures as well as provides functional capability for audio, high audio porting, and user interface with a hall-effect switch and magnet. The user friendly kickstand is strong, sturdy, stable, easy to use and reliable. Advantageously, the multi-functional (multiple function) kickstand is operatively connected and integrally part of the mobile phone or other portable electronic device rather than part of a separate protective carrying case to enclose or encase the mobile phone or other portable electronic device.
The novel kickstand mechanism can rotate outwardly away from the phone or other electronic device, allowing a user to orient the phone or other electronic device in landscape mode at a prescribed angle.
This improved kickstand mechanism resolves prior problems and can include many unique features:
1. A small modular base can result in less metal and lighter weight and can cooperate with the kickstand for improved antenna performance.
2. A finger pick on the underside of the kickstand can provide easy affordance of the kickstand, and can also serve as an audio channel for a high audio speaker.
3. A small cylindrical depression can be provided underneath the kickstand to house a magnet, which when used with a hall-effect sensor inside the phone or other electronic device, relays to software in the circuitry of the phone or other electronic device, that the kickstand is open. There are several user interface (UI) features integrated into the kickstand sensing which results in improved user experience.
4. A slight angled surface at the contact end of the kickstand can be provided to increase the stability of the kickstand.
5. Kickstand opening feature creates an intuitive “push here” functionality to enhance ease of opening the kickstand.
The modular kickstand has superior technical merit and can encompass numerous areas:
a. Kickstand triggering UI change when the state of the kick-stand changes (opened vs. closed). This can be enabled by the magnet embedded in the kickstand tip and hall-effect sensor placed in the electronics device.
b. Fingerpick combined with a loudspeaker port.
c. Small modular base for the kickstand.
The modular kickstand mechanism can provide an integrated kickstand which is integrally connected to the portable phone or other electronic device. The modular kickstand mechanism provides a solution which is applicable across multiple platforms as a clean and space saving solution. Desirably, the modular kickstand mechanism also enhances audio quality of the mobile phone or other electronic device and prevents and minimizes blocking of the audio path.
The modular kickstand can be embedded or integrated with the housing of the mobile phone or other electronic communications device. The modular kickstand can have a fingerpick as well as a magnet that actives a hall-effect sensor which turns on the user interface (UI) for a landscape mode or portrait mode with an accelerometer.
In one embodiment, a kickstand assembly is provided with an electronic communications device which can be moveable from a landscape orientation to a portrait orientation and vice versa. The electronic communications device can comprise a housing having a front comprising a frame with a front surface and having a back with a back surface. An electronic visual display can be secured to the frame in proximity to the front surface for displaying images. A kickstand mechanism can be operatively connected to the back of the housing. The back of the housing can define a cavity which can provide a kickstand compartment for receiving the kickstand mechanism. The kickstand mechanism can include a kickstand comprising an arm with an inner end which is pivotally connected to the housing and can have an outer end positioned opposite the inner end. The outer end of the arm can be movable from a closed storage position within the kickstand compartment to an open position disposed outwardly of the kickstand compartment for supporting the electronic communications device in one of the orientations.
Advantageously, a magnet can be secured to the outer end of the kickstand and at least one sensor can be provided, such as in the interior circuitry of the electronic communications device and/or user interface (UI). The sensor cooperates with and senses the location of the magnet for detecting the position of the kickstand.
The kickstand mechanism can comprise a channel for an audio speaker and/or can comprise an antenna. The kickstand mechanism can define a speaker port and can have a portion for enhancing audio quality and substantially preventing blocking of an audio path to the speaker port. The kickstand mechanism can further comprise a portion for facilitating grasping of the arm and/or can comprise at least one cam for facilitating movement of the kickstand. The kickstand mechanism can include a biasing mechanism for biasing and urging the kickstand towards the open position. The kickstand can also have grooves for enhancing movement and pivoting of the kickstand to the open position.
The electronic communications device can include at least one control for controlling the display of the images. The electronic communications device can comprises a portable electronic device, such as: a radiotelephone, cellular (cell) phone, mobile phone, smart phone, qwerty phone, flip phone, slider phone, android phone, tablet phone, camera phone, clamshell device, portable networking device, portable gaming device, mobile communications device, personal digital assistant (PDA), wireless e-mail device, a two way pager, internet communication device, android tablet, ipod, ipad, kindle, electronic reading device, electronic photo frame, digital photo frame, digital picture frame, video player, audio player, electronic calculator, portable digital television (TV), electronic monitor, blackberry, tablet device, video device, computer, netbook, data sharing device, wireless device, handheld electronic communications device, and combinations of any of the preceding.

The modular kickstand mechanism, kickstand, fingerpick, bracket, and tubular member can be of the same or different materials and can be fabricated or molded of: plastic, metal, impact-resistant plastic, non-magnetic metal, magnetically attractive metal, rigid material, composite material, wood, or combinations of any of these materials. The small modular base of the kickstand mechanism can result in less metal in the assembly and can achieve a lighter weight and improved antenna performance.
A hall-effect sensor is a transducer that varies its output voltage in response to a magnetic field. Hall-effect sensors can be used for location detection, positioning, proximity switching, and current sensing applications. The hall-effect sensor can operate as an analogue transducer and directly return a voltage. With a known magnetic field, its distance from the hall-plate of the hall-effect sensor can be determined. Using hall-effect sensors can also be used to measure current without interrupting the circuit. The hall-effect sensor can be combined with circuitry that allows the device to act in a digital (on/off) mode and can be characterized as a hall-effect switch.
