DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The aforementioned illustrations and following detailed descriptions are exemplary for the purpose of further explaining the scope of the instant disclosure. Other objectives and advantages related to the instant disclosure will be illustrated in the subsequent descriptions and appended drawings.
FIG. 1 is an exploded view of a housing having activated structure. Referring to FIG. 1, the activated structure enables triggering of a remote switch 92 of a device 9. In the instant embodiment, a desktop personal computer is taken as an example and the housing 1 represents the computer housing thereof. The device 9 represents an optical disk drive and the switch 92 is the button allowing for opening a disk try 94. However, the instant disclosure can be adapted to any device with an outer case acting as a user interface.
The housing 1 comprises a housing body 11 and a front panel 12 disposed at the front of the housing body 11. The device 9 is installed in the housing body 11 and concealed behind the front panel 12. The front panel 12 has an inner surface 122, which orientates toward the device 9 and an outer surface 121 opposing thereto. The housing 1 also comprises a latch member 14, which is movably disposed on the inner surface 122 of the front panel 12, a lever 16 pivotally connecting the inner surface 122 and an operation button 18 disposed on the outer surface 121.
FIGS. 1 and 2 show a perspective view of the housing 1. Only the latch member 14 and the lever 16 are shown in FIG. 2 and the remaining members are omitted for clarity. The latch member 14, which ends with a lead-in portion 141 at one end and an activating portion 142 at the other end, is slidably disposed on the inner surface 122. As shown in FIG. 2, the lead-in portion 141 is formed with a lead-in ramp 1412 orientating toward the operation button 18. The activating portion 142 is formed with an activating ramp 1422 aligning the lever 16. The latch member 14 resembles a strip and the protruded lead-in portion 141 connects to the activating portion 142 via an extending portion 143. The length of the extending portion 143 is adjustable according to the distance between the operation button 18 and the switch 92. The extending portion 143 also connects the inner surface 122 of the front panel 12 in a mobile manner.
In the instant embodiment, the latch member 14 moves substantially linearly. The extending portion 143 is formed with a pair of guiding holes 145 to receive a pair of guiding post 124 from the front panel 12 respectively. In addition, a plurality of positioning plates 146 stretches out from the front panel 12, and retaining hooks on either side of the extending portion 143 retain the position thereof. However, the instant disclosure is not limited thereto. For example, the positioning plates 146 can be omitted and the latch member 14 is secured on the inner surface 122 by screws, which passes through the guiding holes 145 and selectively contacts the guiding posts 124. Alternatively, the latch member 14 may be fastened onto the inner surface 12 in a rotatable manner. More specifically, the extending portion 143 pivotally connects the inner surface 122 acting as a hinge and the lead-in portion 141 and activating portion 142 swing accordingly.
With reference to FIG. 2 the instant embodiment also comprises a first elastic member 15, which returns the latch member 14 back to an original position (i.e. before the operation button 18 is pressed). The first elastic member 15 can be a latch member spring accommodated in a receiving hole 1430 of the extending portion 143. The placement of the latch member spring may vary. For example, one end of the latch member spring can be attached on a fixed tab 1432 of the extending portion 143 and the other end thereof is fastened onto the inner surface 12 of the front panel 12. Additionally, as shown in FIG. 2, the latch member spring is attached on the extending portion 143, and a fixed plate 125 stretching out from the inner surface 122 retains the other end thereof.
Please refer to FIG. 1. The lever 16 facilitates the latch member 14 to trigger the switch 92. One end of the lever 16 pivotally connects to the front panel 12 while the other end thereof swings between the activating portion 142 of the latch member 14 and switch 92. As shown in FIG. 1, the lever 16 is pivotally connected to the inner surface 122 of the front panel 12 via a pivot portion 161. A triggering portion 162 extends from the pivoting portion 161 and selectively contacts the activating portion 142 and switch 92. Please refer to FIG. 3. The triggering portion 162 abuts the activating portion 142 which is at proximate to the switch 92 of the device 9.
As shown in FIG. 1, a smooth surface 163 is formed on the lever 16 to ensure effortless movement over the activating ramp 1422. Moreover, a third elastic member 17 is disposed at one end of the lever 16 to facilitate the return of the lever 16 after forcibly tilted.
Please refer to FIG. 2 showing the detail of the engagement between the lever 16 and the front panel 12. Specifically, the pivoting portion 161 has a pair of pivot pins 1613 projecting from either end thereof. The inner surface 122 of the front panel 12 has a pair of pivot plates 126 conforming to the pivot pins 1631 and connecting thereto. Additionally, the pivoting portion 161 is formed with a recessed portion 1610, and a spring holder 1611 extends laterally across the recessed portion 1610. The third elastic member 17 may be a torsion spring looping the spring holder 1611. Furthermore, the third elastic member 17 is fastened by lever 16 and front panel 12 from either end. In the instant embodiment, one end of the torsion spring is inserted into the lever 16 whereas the other end thereof attaches to a retaining hook 128 extending from the inner surface 122. In addition, the lever 16 may be integrally formed with the third elastic member 17, which abuts the inner surface 122.
Please refer to FIGS. 1 and 2. The operation button 18 is arranged on the outer surface 121 of the front panel 12 and initializing a series of motions. More specifically, as shown in FIG. 2, the operation button 18 stretches out from the front panel 12 and contacts the lead-in portion 141 of the latch member 14. When the operation button 18 is pressed, the latch member 14 also shifts accordingly. The activating portion 142 further presses the triggering portion 162 which then spins slightly by using the pivoting portion 161 as a hinge. The triggering portion 162 finally contacts and activates the switch 92 of the device 9.
Please refer to FIG. 2A showing a perspective view of the operation button 18 assembled with the front panel 12. The operation button 18 has a pair of retaining tabs 182, an assembly post 184 disposed between the retaining tabs 182, a second elastic member 185 looping the assembly post 184 and a pair of pushing tabs 186 disposed on either side of the assembly post 184. The retaining tabs 182 movably engage with the front panel 12 for minimizing the shift of the operation button 18. For instance, the front panel 12 has a connection part 123 (shown in dotted line) aligning parallel to the inner surface 122. The tips of the retaining tabs 182 resemble retaining hooks which grip a side hole 1232 on the connection part 123. The number of the retaining tabs 182 may be at least one. The second elastic member 185 facilitates the return of the operation button 18 to an original position (i.e. before pressed). In the instant embodiment, the second elastic member 185 is a compression spring enclosing the assembly post 184 and disposed between the connection part 123 and a back of the operation button 18. The connection part 123 is also formed with a through hole 1234 to allow penetration of the assembly post 184. The pushing tabs 186 are formed with pushing ramps 1861, which pass through the side hole 1232 and presses against the lead-in ramp 1412.
Please refer to FIG. 3 in conjunction with FIG. 4 showing a serial movement of the housing 1. As shown in FIG. 3, the operation button 18 is remote from the switch 92 of the device 9. When a user presses the operation button 18, the pushing ramps 1861 abut the lead-in ramp 1412 and provide a force driving the latch member 14. As shown in FIG. 3, while the latch member 14 shifts downward, the activating portion 142 travels further down and abuts the smooth surface 163. The lever 16 tilts toward the device 9 by the force from the latch member 14. In FIG. 3, the lever 16 spins clock-wise and the triggering portion 162 activates the switch 92 to open the disk tray 94.
In summary, the latch member 14 communicates between the operation button 18 and switch 92 so the front panel 12 is available for button layout reconfiguration. The user interface of an electronic device has more freedom in design because the arrangement of buttons or ports no longer needs to be an exact map of the corresponding member. In other words, the latch member 14 provides a trigger system which presents the operation button 18 as a virtual position of the actual switch 92. Hence the user interface can be reconfigured instead of confined by the interior layout.
The descriptions illustrated supra set forth simply the preferred embodiments of the instant disclosure; however, the characteristics of the instant disclosure are by no means restricted thereto. All changes, alternations, or modifications conveniently considered by those skilled in the art are deemed to be encompassed within the scope of the instant disclosure delineated by the following claims.
