DETAILED DESCRIPTION

[0012] Generally, in order to maintain or enhance aesthetics of a computing device, various input-output (I/O) interfaces, such as ports, of the computing device may be so located that such I/O interfaces are not visible to a user. For example, the various ports and connectors in a desktop personal computer (PC) or an all-in-one PC are usually provided at a rear of a cabinet or housing of the PC. This is so done so that during general usage, the user is unable to view them, and the aesthetic appeal of the computing device is not hindered. While such provisions may work in the favour of the aesthetic appeal of the computing device, it may adversely affect accessibility of the I/O interfaces to the user. For example, the user may find it inconvenient to access such awkwardly located I/O interfaces. In other examples, the user may end up damaging either the computing device or oneself while attempting to access the I/O interfaces.

[0013] Examples of a fastener for a concealable interface panel, for example, for use with a computing device, are described herein. In an example, the fastener has a simple, yet effective design for use with the concealable interface panel. In an example, the concealable Interface panel can have an input-output (I/O) access point, such as a port or a connector, of the computing device. The computing device can be provided with a simple mechanism by way of which the concealable interface panel can be concealed when not in use and unlocked for being conveniently

accessible for use. For instance, the computing device can be an all-in-one (AIO) computing device and the concealable interface panel can be provided in the AIO computing device, such that the concealable interface panel remains obscured from access when not in use but can be promptly exposed for access.

[0014] In one example, the computing device includes a chassis, a concealable interface panel which can be concealed in the chassis, and a fastener for engaging and disengaging the concealable interface panel so as to conceal or reveal the concealable interface panel. The chassis can have a recess for accommodating the concealable interface panel, a guide channel for accommodating the fastener, and can also have an opening in proximity of the guide channel which serves to allow engagement and disengagement of the concealable interface panel to and from the chassis.

[0015] The concealable interface panel can be swivelably or pivotably coupled to the chassis using a biasing member, such that the concealable interface panel can move into the recess against a force of the biasing member and locked therein and can move out of the recess by the force of the biasing member upon unlocking. In other words, the concealable interface panel, when unlocked for being accessed, can flip open under the force of the biasing member and reveal the I/O access point on the concealable interface panel. The concealable interface panel is formed as having a housing which can be mounted to the chassis and can have an interlocking member which can cooperate with the fastener. The I/O access point can be housed in the housing, such that the I/O access point not remain readily accessible to a user when the concealable interface panel is moved into the recess. For example, when stowed into the housing, the I/O access point may be positioned at a rear of the computing device and a user, operating the computing device from a front of the computing device may not be able to view or conveniently access the I/O access point.

[0016] The fastener is disposed in the guide channel of the chassis so that it can exhibit a slidable movement in the guide channel for cooperating with the

concealable interface panel. The fastener includes an engagement slot which is substantially aligned with the opening in the chassis and which can receive the interlocking member of the concealable interface panel. The fastener further includes an elastic member which can abut against the chassis, such that when the fastener exhibits the sliding movement, it does so under influence of the biasing force of the elastic member. The engagement slot of the fastener can detachably engage with the interlocking member when the concealable Interface panel is moved into the recess. In such a case, the interlocking member can protrude through the opening in the chassis to lock with the engagement slot. In an example, the interlocking member can have a saw-tooth shaped snap-fit design and when brought in engagement with the fastener, it can cause the fastener to slide with respect to the chassis against the biasing force of the elastic member and then snap into engagement with the fastener. For unlocking or disengaging, the fastener can be slid with respect to the chassis, against the biasing force of the elastic member, to disengage the interlocking member from the fastener. In said example, the elastic member of the fastener can be biased appropriately for operating in the above explained manner.

[0017] Accordingly, as explained above, the present subject matter provides for a simple mechanical assemblage which can provide for quick, convenient, and effective concealing of or access to the I/O access points on the concealable interface panel. In addition, the design is cost-effective and has easy manufacturability.

[0018] The above aspects are further described in conjunction with the figures, and in associated description below. It should be noted that the description and figures merely illustrate principles of the present subject matter. Therefore, various arrangements that encompass the principies of the present subject matter, although not explicitly described or shown herein, may be devised from the description and are included within its scope. Additionally, the word “coupled” is used throughout for

5 clarity of the description and can include either a direct connection or an indirect connection.

[0019] Figure 1 illustrates a schematic of a computing device 100 having a concealable interface panel (CIP) 102 and a fastener 104 therefor, in accordance with an example of the present subject matter. The computing device 100 can be, for example, a laptop personal computer (PC), an all-in-one (AIO) PC, a desktop PC, or a notebook PC. In other examples, the computing device 100 may be a mobiie phone, a tablet PC, a personal digital assistant (PDA), a gaming console, or another type of computing device, in yet other examples, the computing device 100 may be a standalone monitor or a separate display unit usable with a desktop PC. According to an aspect of the present subject matter, the CIP 102 can be concealed within a part of the computing device 100 so that the CIP 102 may not be visible or conveniently accessible, for instance, to a user when operating the computing device 100. However, with a simple mechanism, the CIP 102 may be revealed and can be easily accessible to the user. For instance, in case of the computing device 100 being an all-in-one (AIO) computing device, the CIP 102 can remain hidden until the user actively exposes the CIP 102.

[0020] In said example, the computing device 100 can include a chassis 106 having a recess 108. For instance, in case of the AIO computing device, the chassis 106 can be the cabinet in which the display, the CPU, and other components of the AIO computing device are housed. The CIP 102 includes a housing 110 having an interlocking member 112, the housing 110 being movably mounted to the chassis 106. An input-output (I/O) access point 114 of the computing device 100 can be housed in the housing 110, and as explained earlier, when the CIP 102 is exposed, the user can access the I/O access point 114. According to an aspect, to obscure the CIP 102, the housing 110 can be movable into the recess 108 in the chassis 106 in a concealed state of the CIP 102. in such a state, the I/O access point 114 can remain in a state where it is not readily accessible. In other words, the housing 110 can be moved to be hidden in the recess 108 so that the CIP 102 is concealed, such that the I/O access point 114, for instance, is obscured from view of the user. For

example, in the concealed state, the I/O access point 114 may be positioned at a rear of the computing device 100 and a user, operating the computing device 100 from a front of the computing device 100 may not be able to view or conveniently access the I/O access point 114,

[0021] In addition, the computing device 100 can include the fastener 104 which can cooperate with the Cl P 102. According to the present example, the fastener 104 can also be movably mounted to the chassis 106 and, as mentioned above, can be in operable connection with the CIP 102. Accordingly, the fastener 104 can detachably engage with the interlocking member 112 of the CIP 102, in the concealed state of the CIP 102. Put another way, the fastener 104 can lock with the interlocking member 112 of the CIP 102 to retain the CIP 102 in the recess 108 until the fastener 104 is unlatched.

[0022] Figure 2 illustrates another schematic of the computing device 100 having the CIP 102 and the fastener 104 therefor, in accordance with another example of the present subject matter, in the present example, as mentioned above, the computing device 100 can include the chassis 106, the CIP 102, and the fastener 104. The chassis 106, in addition to the recess 108, includes a guide channel 202 and an opening 204 in proximity of the guide channel 202. As will be explained later, the guide channel 202 can receive the fastener 104 and the opening 204 can receive the interlocking member 112 of the CIP 102.

[0023] The CIP 102 is pivotably coupled to the chassis 106 using a biasing member to be movable into the recess 108 in the chassis 106 against a force of the biasing member and to be movable out of the recess 108 by the force of the biasing member. As explained above, the housing 110 is mounted to the chassis 106 to mount the CIP 102 to the chassis 106 and the housing has the interlocking member 112 and houses the I/O access point 114 housed in the housing. When the CIP 102 is moved into the recess 108, the I/O access point 114 may not be readily accessible, as described above.

[0024] The fastener 104 is disposed in the guide channel 202 of the chassis 106 to be able to exhibit a sliding movement in the guide channel 202. In the present example, the fastener 104 includes an engagement slot 206 and an elastic member 208. The engagement stot 206 which can be substantially aligned with the opening 204 in the chassis 106, for example, for the interlocking member 112. in addition, the elastic member 208 can cooperate with the chassis 106 to cause the sliding movement of the fastener 104 with respect to the chassis 106 under influence of a biasing force of the elastic member 208. For instance, the eiastic member 208 is so coupled to the chassis 106 that for detaching the fastener 104 from the interlocking member 112, the fastener 104 may have to be actuated against the biasing force of the eiastic member 208.

[0026] Further, in the concealed state of the CIP 102, for instance, when the CIP 102 is positioned in the recess 108, the engagement slot 206 of the fastener 104 can detachably engage with the interlocking member 112, and, in such a state, the interlocking member 112 can protrude through the opening 204 in the chassis 106 to engage or latch with the engagement slot 206. The detailed structure and operation of the CIP 102 and the fastener 104 in the computing device 100 is explained in further detail with reference to Figures 3A to 9B.

[0026] Figure 3A, Figure 3B, and Figure 3C illustrate the computing device 100, according to an example of the present subject matter. Figure 3A illustrates a front perspective view of the computing device 100 and Figure 3B illustrates a rear perspective view of the computing device 100, in both cases, the CIP 102 being in a concealed state. On the other hand, Figure 3C illustrates a front perspective view of the computing device 100 with the CIP 102 in a revealed state. For the sake of brevity, Figures 3A to 3C are described in conjunction with each other. In the example shown in Figures 3A to 3C, the computing device 100 can be the AID computing device.

[0027] As explained earlier, in the concealed state of the CIP 102, the user of the computing device 100 may be unable to view or readily access the I/O access point 114 on the CIP 102. In the concealed state, the CIP 102 is stowed away in the

recess 108 in the chassis 106 of the computing device 100. As a result the aesthetic appeal of the computing device 100 remains intact in the concealed state of the CiP 102. On the other hand, when the user wants to access the I/O access point 114, the user can conveniently switch the CIP 102 from the concealed state to the revealed state. In the revealed state, as shown in Figure 3C, the CiP 102 can be removed from the recess 108.

[0028] in an example explained earlier, the CIP 102 can be cooperatively coupled to the chassis 106 using the biasing member (not shown in Figure 3A to 3C) and can be inserted into the recess 108 against the force of the biasing member. Accordingly, in said example, the CIP 102 can exhibit a flip-open movement while changing the state from the concealed state to the revealed state. The coupling of the CIP 102 to the chassis 106 is shown in detail in Figure 4A and Figure 48.

[0029] Figure 4A illustrates the CIP 102 with the biasing member 402 while Figure 4B illustrates the CIP 102 assembled to the chassis 106 using the biasing member 402, The biasing member 402 is shown in an unbiased or unloaded condition in Figure 4A. For the sake of brevity, Figures 4A and 48 are explained in conjunction with each other.

[0030] In the example shown in Figures 4A and 48, the housing of the CIP 102 can have a notch 404 which can accommodate one end of the biasing member 402. The other end of the biasing member 402 can be fixedly coupled to the chassis 106, in a manner that during relative movement between the CiP 102 and the chassis 106, the other end of the biasing member 402 which is coupled to the chassis 106 does not move with respect to the chassis 106. When the CiP 102 is stowed into the recess 108, the biasing member 402 is energized from its unloaded condition. Accordingly, when the CIP 102 is unlatched from being locked in the concealed state, the CIP 102 can exhibit the flip-open movement since the CIP 102 moves out of the recess 108 under the force of the biasing member 402 to bring the biasing member 402 in an unloaded state. When the CIP 102 is to be stowed back into the recess 108, the movement of the CIP 102 is against the force of the biasing member 402, which, as explained above, energizes the biasing member 402.

[0031] Coming back to Figure 3A to 30, the CIP 102 can be so mounted into the recess 108 that in the concealed state, the I/O access point 114 may not be readily accessible or visible to the user from a front direction, as shown as an example in Figure 3A. However, at the rear of the computing device 100, the I/O sssss point 114 may be accessible to the user. Furthermore, when the CIP 102 Is flipped-open, the I/O access point 114 may face towards the front direction, for instance, towards a user operating the computing device 100, thereby, becoming conveniently accessible for the user.

[0032] In an example, in the concealed state of the CIP 102, the I/O access point 114 may not be conveniently usable for the user. Accordingly, the user can flip- open the CIP 102 so that the I/O access point 114 faces the user and the user can, for instance, connect an external device into the access point 114. Once the external device is connected, the user may then stow the CIP 102 away again into the recess 108, such that the external device remains connected while the I/O access point 114 faces away from the user. For disconnecting the external device, the user may again flip-open the CIP 102 by actuating the fastener 104 and may be able to readily access the I/O access point 114.

[0033] Figure 5A and Figure 5B illustrate the CIP 102, in accordance with an example of the present subject matter. While Figure 5A illustrates a front perspective view of the CIP 102, Figure 5B illustrates a rear perspective view of the CIP 102. For the sake of brevity, Figure 5A and 5B have been described herein in conjunction with each other.

[0034] As explained earlier, the CIP 102 has the housing 110 which has the interlocking member 112 and houses the I/O access point 114. The interlocking member 112 can be formed as a snap-fit lug having a saw-toothed shape and capable of flexing to engage with the fastener 104. Further, the I/O access point 114 can be a universal serial bus (USB) port, a type-C USB port, an audio or a microphone jack, an audio/video (A/V) port, a High-Definition Multimedia Interface (HDMS) port, an ethernet port, a Video Graphics Array (VGA) port, or a memory card reader slot. In one example, the CIP 102 can bear a plurality of I/O access points

10

114. In said example, the CIP 102 can have more than one I/O access point 114 of the same type. For instance, the CIP 102 may have a plurality of USB ports and HDMI ports, whereas it may have a single VGA port and a single microphone jack. In addition, the housing 110 can have mounting lugs 502 for mounting the CIP 102 to the chassis 106 and also has, as mentioned with reference to Figures 4A and 4B, the notch 404 for accommodating the biasing member 402. Mounted at the chassis 106 using the mounting lugs 502, the CIP 102 can pivot about a mounting point (not shown) on the chassis 106 for being brought into the revealed state from the concealed state and vice-versa.

[0035] The operation of the CIP 102 in conjunction with the fastener 104 for latching in the concealed state and unlatehing to be in the revealed state is described in further detail with reference to Figures 6 to 8C.

[0036] Figure 6 illustrates a schematic of a fastener, such as the fastener 104, in accordance with an example of the present subject matter. In said example, the fastener 104 includes a flat body 602, a first end 604, a second end 606, and an engagement slot 206. The second end 606 can have an elastic member 208 which can be a spring plate extending along a lateral direction of the flat body 602. As an example, the lateral direction can be a direction substantially orthogonal to a line connecting the first end 604 and the second end 606 of tine fastener 104. In addition, the engagement slot 206 can be provided between the first end 604 and the second end 606 to lock with the CIP 102, for instance, in the concealed state of the CIP 102. [0037] Figure 7A, Figure 7B, and Figure 7C illustrate various views of the fastener 104 and chassis 106, according to an example of the present subject matter. Figure 7 A and Figure 7B show right and left perspective views, respectively, of the fastener 104 assembled with the chassis 106, whereas Figure 7C illustrates the fastener 104 and the chassis 106 in exploded view. For the sake of brevity, Figures 7A to 7C are described in conjunction with each other.

[0038] The chassis 106 can include the guide channel 202 and the opening 204, as described previously. In an example, the guide channel 202 can be formed by two guide rails 702-1 and 702-2 that are substantially parallel and facing each other. The

guide channel 202 so formed between the guide rails 702-1, 702-2 can have the fastener 104 slideably disposed therein. In an example, the fastener 104 can be formed of a metallic material, a polymer, or of a combination thereof. For example, few portions of the fastener 104 can be made of metal while others of polymer, depending on balancing the strength, flexibility, and cost of the fastener 104 to be achieved.

[0039] Further, the chassis 106 can include a reaction iug 704 which is positioned in proximity of the guide channel 202 and which can abut against the elastic member 208 of the fastener 104 to bias the elastic member 208, such that the engagement slot 206 of the fastener 104 is substantially aligned with the opening 204 in the chassis. In said example, the engagement slot 206 can also be in the form of a cavity in the flat body 602 of the fastener 104. For instance, as mentioned previously, the elastic member 208 can be designed as a spring plate and the reaction lug 704 can abut against the elastic member 208 to bias the fastener 104 in the appropriate direction.

[0040] In the present example, as shown in Figure 7A to 7C, the reaction lug can be provided at one end of the guide channel 202, such that the sliding movement of the fastener 104 with respect to the chassis 106 is regulated by the cooperation between the reaction lug 704 and the elastic member 208. The bias created in the elastic member 208 due to abutment against the reaction lug 704 can determine a force which may have to applied on the fastener 104 to actuate it against the bias to disengage the fastener 104 from the interlocking member 112 of the CIP 102. For instance, the reaction Iug 704 and the guide channel 202 can be positioned in relation to each other based on various factors, such as design of the fastener 104, design of the elastic member 208, design of the chassis 106 and the opening 204 therein, and an actuation force and travel of the fastener 104 that the computing device 100 is designed for.

[0041] Further, the fastener 104 has the Hat body 602 having lateral walls 706 which abut against the parallel guide rails 702-1, 702-2 and facilitate the sliding movement of the fastener 104 in the guide channel 202. For instance, the lateral

12 walls 706 can be the walls of the fastener 104 connecting the first end 604 to the second end 606. In addition, the fastener 104 can include a snap-fit rib 708 cm each lateral wall 706. In an example, the snap-fit rib 708 can be formed as an overhanging, cantilevered arm coupled at one end to the flat body 602 and, at the other end, extending away from the flat body 602, and capable of flexing to create a snap fit with the guide rail 702-1 , 702-2. The provision of the snap-fit ribs 708 cm the fastener 104 disengageably couples the fastener 104 to the chassis 106. In other words, the provision of the snap-fit ribs 708 allows the fastener 104 to be irremovably disposed in the guide channel 202 in such a manner that the fastener 104 is able to slide but is not withdrawn from the guide channel 202 during the movement, Further, the reaction tog 704 also prevents the fastener 104 from being withdrawn from the guide channel 202, for instance, from the other end.

[0042] In addition, the fastener 104, at the first end 604, can have a gripping portion 710, for instance, for the user to actuate the fastener 104 for disengaging with the interlocking member 112 of the CIP 102, in the concealed state of the CIP 102. For example, the gripping portion 710 can be sideways extension which allows the user to actuate the fastener 104. In the same or another example, the gripping portion 710 can have multiple ribs provided thereon for enhancing gripping by the user.

[0043] Figure 8A, Figure 8B, and Figure 8C illustrate the CIP 102 and fastener

104 assembled in the computing device 100, according to an example of the present subject matter. In the present example, Figures 8A and 8B illustrate the CIP 102 in the concealed state, Figure 8A illustrating a perspective view of the assembly while Figure 8B illustrating a cross-sectional view of the assembly. For the sake of brevity, Figure 8A to 8C have been described in conjunction with each other.

[0044] In the concealed state, the interlocking member 112 of the CIP 102 can engage with the engagement slot 206 of the fastener 104 so teat the CIP 102 is retained in the recess 108. In such a state, the opening 204 is substantially aligned with the engagement slot 206, such that the interlocking member 112 can pass through the opening 204 and engage with the engagement slot 206. For instance,

the interlocking member 112 can be formed as a snap-fit lug with the saw-tooth profile which allows the interlocking member 112 to easily enter the engagement slot 206 against the bias force of the elastic member 206. Once the saw-tooth profile has fully entered the engagement slot 206, the snap-fit lug snaps and locks with the engagement slot 206. In the concealed state, the CIP 102 is stowed into the recess 108 and the biasing member 402 is energized such that it is biased in a direction to automatically reveal the CIP 102 as soon as the interlocking member 112 disengages.

[0045] To disengage, as explained previously, the fastener 104 may be actuated against the bias force of the elastic member 208 so that the interlocking member 112 disengaged from the engagement slot 206. For instance, the engagement slot 206 may have lesser width than the opening 204 such that upon disengagement from the engagement slot 206, the interlocking member 112 does not latch with the opening 204 in the chassis 106. When the CIP 102. Is so unlatched, the CIP 102 can exhibit the flip-open movement and can move out of the recess 108 under the force of the biasing member 402 to bring the biasing member 402 in a neutral or unbiased state.

[0046] Although aspects of the fastener 104 for the CIP 102 have been described in a language specific to structural features and/or methods, it is to be understood that the subject matter is not limited to the features or methods described. Rather, the features and methods are disclosed as examples of the fastener 104 for the CIP 102.
