The present invention will now be described in detail with reference to the accompanying drawings, wherein the same reference numerals will be used to identify the same or similar elements throughout the several views. It should be noted that the drawings should be viewed in the direction of orientation of the reference numerals.
Referring to FIGS. 1 and 2, a foldable holster for a mobile electronic apparatus according to a first embodiment of the present invention includes a first foldable plate 10, a base plate 11, a second foldable plate 12, an extended device 20, and a control device 30.
The base plate 11 is connected to the first foldable plate 10 at one lateral edge of the base plate 11, and is connected to the second foldable plate 12 at the other lateral edge of the base plate 11. The base plate 11 is provided with at least one retaining element 13 for accommodating the mobile electronic apparatus 40. Each of the first foldable plate 10, the base plate 11 and the second foldable plate 12 has a covering surface for covering an upper surface of the mobile electronic apparatus. The covering surface is larger than or equal to the upper surface of the mobile electronic apparatus 40. The first foldable plate 10 and the second foldable plate 12 can be folded inwardly along the lateral edges of the base plate 11 so as to cover the mobile electronic apparatus 40 in a folded status/position relative to the base plate 11. Alternatively, the first foldable plate 10 and the second foldable plate 12 can be unfolded outwardly in an unfolded status/position relative to the base plate 11 to expose the mobile electronic apparatus 40 to the user.
The extended device 20 has a connector 21 for connecting the mobile electronic apparatus 40 to an auxiliary unit 22, for example, a keyboard. The extended device 20 is installed on the first foldable plate 10, and provides at least one function to the mobile electronic apparatus 40 via the connector 21. It should be noted that, in addition to the keyboard, the auxiliary unit 22 can also be a touch pad, a display screen, a display light, a GPS/TV/GSM antenna, etc.
The control device 30 comprises a switch 31 which is provided on the first foldable plate 10 and is connected to the auxiliary unit 22 of the extended device 20 for enabling and disabling the auxiliary unit 22; and a sensor 32 which is provided on the first foldable plate 10 and is connected to the switch 31 for detecting the actions of the first foldable plate 10 and the base plate 11. When the sensor 32 detects that the first foldable plate 10 11 is in an unfolded position relative to the base plate 11, the switch 31 will be set to a “turn-on” mode. On the other hand, when the sensor 32 detects that the first foldable plate 10 is in a folded position relative to the base plate 11, the switch 31 will be set to a “turn-off” mode. The sensor 32 may be a photo-inductive element or a magnetic-inductive element, for examples. In addition, the sensor 32 may be installed on the base plate 11 or on the mobile electronic apparatus 40.
According to the first embodiment of the present invention, the first foldable plate 10 and the base plate 11 can protect the mobile electronic apparatus 40 and the auxiliary unit 22 from damage. The extended device 20 provides at least one additional function such as I/O function to enhance the expandability of the mobile electronic apparatus 40. The auxiliary unit 22 can be turned “on” or “off” in accordance with the folded or unfolded status/position of the first foldable plate 10 relative to the base plate 11 so as to prevent unnecessary power consumption. Moreover, in case that the auxiliary unit 22 is a keyboard or a touch device, the foldable plate 10 can prevent the user from inadvertently operating the auxiliary unit.
FIG. 3 illustrates a holster in accordance with a second embodiment of the present invention. Different from the first embodiment, the switch 31 and the sensor 32 of the control device 30 in the second embodiment are not provided on the first foldable plate 10, but provided on the auxiliary unit 22 of the extended device 20.
FIG. 4 illustrates a holster in accordance with a third embodiment of the present invention. Different from the electronic controller of the first and second embodiments, the control device 30 in the third embodiment is a mechanical controller. By using the mechanical controller 30, the auxiliary unit 22 can be enabled or disabled according to a folded or an unfolded status/position of the first foldable plate 10 relative to the base plate 11 without using the sensor. The control device 30 according to the third embodiment can be installed on the first foldable plate 10, the base plate 11, the auxiliary unit 22, or the mobile electronic apparatus 40.
FIG. 5 illustrates a holster in accordance with a fourth embodiment of the present invention. In the fourth embodiment, the control device 30 can only turn off the auxiliary unit 22 when the folded status/position of the first foldable plate 10 relative to the base plate 11 is detected, but cannot turn on the auxiliary unit 22 simply when the unfolded position of the first foldable plate 10 relative to the base plate 11 is detected. The illustrated holster for the mobile electronic apparatus further includes a manual switch 50, by which a user can manually turn on the auxiliary unit 22 when the first foldable plate 10 is in the unfolded status/position relative to the base plate 11. Therefore, when the first foldable plate 10 is folded relative to the base plate 11, the auxiliary unit 22 can be turned off automatically by the control device 30. If a user wants to turn the auxiliary unit 22 on, he needs to first unfold the first foldable plate 10 and the base plate 11, and then turn on the auxiliary unit 22 by manually switching the manual switch 50. This feature further prevents unnecessary power consumption because the user may not want to use the auxiliary unit 22 every time when he/she unfolds the first foldable plate 10. The manual switch 50 according to the fourth embodiment can be provided on the auxiliary unit 22, the first foldable plate 10, the base plate 11, or the mobile electronic apparatus 40.
FIG. 6 illustrates a holster in accordance with a fifth embodiment of the present invention. In the fifth embodiment, the extended device 20 includes more than one auxiliary unit 22. The auxiliary units 22 can be enabled and disabled by the control device 30 in accordance with the folded or unfolded status/position of the first foldable plate 10 relative to the base plate 11. For example, the extended device 20 includes two auxiliary units A and B. When the first foldable plate 10 is folded relative to the base plate 11, both auxiliary units A and B can be turned “off” by the control device 30 automatically. When the first foldable protective plate 10 is unfolded relative to the base plate 11, the auxiliary units can be controlled by the control device 30 in different predetermined ways. For example, when the first foldable protective plate 10 is unfolded relative to the base plate 11, either one or both auxiliary units A and B are enabled, or neither of the auxiliary unit A and B is enabled. It should be noted that the user may change the setting so as to control the on/off status of the auxiliary units in his/her preferred way when the first foldable protective plate 10 is unfolded relative to the base plate 11.
Although the extended device 20 and the mobile electronic device 40 are electronically connected by a tangible cable according to the above-mentioned embodiments, they can also be connected in a non-contacting form such as wireless transmission.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
