DETAILED DESCRIPTION OF THE INVENTION

[0008] (Background to this disclosure) In recent aircraft, each seat is equipped with electronic devices such as personal monitors that allow passengers to watch movies, play games, read books, check flight status, and the like, or seat monitors that can provide other in-flight entertainment (e.g., in-flight entertainment (IFE) devices). Conventionally, electronic devices have been equipped with a monitor and a connection (outlet) for accessory devices such as earphone plugs, USB connectors, and Wi-Fi (registered trademark) communications. However, while monitors have a long life cycle, these connection parts often require updates due to technological changes and may have a shorter life cycle than the monitor. Therefore, electronic devices with detachable and replaceable monitors and connection parts are beginning to appear. It is desirable that only designated staff, such as those designated for maintenance, be allowed to attach and detach the monitor and connection parts.

[0009] Patent document 1 describes an electronic device housing in which a release hole that penetrates to the outside is provided in the part of the housing body that faces the locking claw when the battery cover is attached to the housing body, and the locked state is released by inserting a rod-shaped member into this release hole and pressing the locking claw.

[0010] However, there is a possibility that passengers on an aircraft may carry rod-shaped objects, such as toothpicks used during meals. In such a case, the configuration described in Patent Document 1 may involve a passenger potentially disengaging the lock through mischief or other means. As a result, the monitor or its components may be damaged or malfunction. Therefore, there is a need for a structure that makes it difficult for anyone other than predetermined staff (e.g., mechanics) for maintenance or other purposes to use tools other than the designated rod-shaped objects (e.g., toothpicks) to disengage the lock.

[0011] Hereinafter, with reference to the drawings as appropriate, detailed descriptions of embodiments that specifically disclose the configuration and operation of the connection device according to the present disclosure will be provided. However, unnecessary detailed descriptions may be omitted. For example, detailed descriptions of well-known matters or redundant descriptions of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure and are not intended to limit the subject matter recited in the claims. Although the following description of the connection device will be made using an electronic device such as an IFE device, the connection device may be used for any device, not just electronic devices. In this specification, the "up-down direction" is defined as the direction in which the monitor unit 10 and the peripheral bar unit 20 are connected as shown in FIG. 1. The "left-right direction" is defined as the longitudinal direction of the monitor unit 10 or the peripheral bar unit 20, among directions substantially perpendicular to the up-down direction. The "outside" is defined as the direction away from the component in the left-right direction, and the "inside" is defined as the direction opposite to the "outside" in the left-right direction. The left side is defined as the left side of the paper in the left-right direction, the right side is defined as the right side of the paper, the top side is defined as the top side of the paper in the up-down direction, and the bottom side is defined as the bottom side of the paper.

[0012] (Embodiment) 1. Electronic Device 1 First, the electronic device 1 will be described. FIG. 1 is a diagram showing an example of an electronic device, where (a) shows the front side as seen by a user (passenger) and (b) shows the back side as seen by the user (passenger). The electronic device 1 is, for example, an IFE device installed around a seat on an aircraft or the like. The electronic device 1 includes a monitor unit 10 and a peripheral bar unit 20. The monitor unit 10 has a built-in display and monitor. The peripheral bar unit 20 is provided with connection sections (e.g., earphone jack, USB port) for connecting to accessory devices such as earphone plugs and USB connectors. The monitor unit 10 is easy to use over the long term. However, the connector standards of the peripheral bar unit 20 often change over time, and there is a high probability of malfunction due to the frequent physical contacts such as sockets, which increases the need for replacement.

[0013] 2. Removing the Monitor Unit 10 and Peripheral Bar Unit 20 Next, the removal of the monitor unit 10 and the peripheral bar unit 20 will be described. FIG. 2 is a diagram showing an example of the rear surface of the electronic device and an access hole. FIG. 2(a) is a diagram showing the entire rear surface of the electronic device, and FIG. 2(b) is an enlarged view of the access hole and its surroundings. FIG. 3 is a diagram showing the monitor unit and the peripheral bar unit when connected. FIGS. 4(a) to 4(e) are diagrams explaining the process of removing the monitor unit and the peripheral bar unit, with the state changing from (a) to (e) over time. Also, for simplicity of explanation, FIGS. 4(a) to 4(e) only show the configuration of the left side of the rear surface of the peripheral bar unit 20, but the following explanation of FIG. 4 is equally applicable to the configuration of the right side of the rear surface.

[0014] As shown in each of Figures 2(a) and 2(b), an access hole 21 is provided in the peripheral bar unit 20 on the rear side. By pushing a tool 30, such as a rod-shaped tool, into the access hole 21, staff (e.g., a maintenance technician for the electronic device 1) can remove the monitor unit 10 and the peripheral bar unit 20. In this case, since the monitor unit 10 is fixed to the aircraft, the peripheral bar unit 20 will be removed from the fixed monitor unit 10. Two access holes 21 are usually provided, one on each side.

[0015] As shown in FIG. 3, latches 22 are provided on both the left and right sides of the housing 24 of the peripheral bar unit 20. The housing 24 has four outlines and is formed into a rectangular shape with adjacent outlines intersecting at approximately right angles. The latches 22 are biased by springs BN (see FIGS. 4(a) to 4(e)), and receive forces directed outward in the left-right direction of the housing 24 from the springs BN. The latches 22 of the peripheral bar unit 20 are engaged with the engaging portions 11 of the monitor unit 10, thereby maintaining a physical connection between the monitor unit 10 and the peripheral bar unit 20. The monitor unit 10 and the peripheral bar unit 20 are also physically and electrically connected by the connecting portion 13 (plug) of the monitor unit 10 and the connecting portion 23 (receptacle) of the peripheral bar unit 20. By pushing a tool 30 through an access hole 21 provided in the housing 24 as shown in FIG. 2, a force indicated by arrow F is applied to the inside of the housing 24. Then, the latch 22 biased by the spring BN is pushed toward the inside of the housing 24 of the peripheral bar unit 20, and the latch 22 separates from the engagement portion 11, thereby releasing the connection between the monitor unit 10 and the peripheral bar unit 20, and the monitor unit 10 and the peripheral bar unit 20 are removed.

[0016] With reference to FIGS. 4(a) to 4(e), the removal of the monitor unit 10 from the peripheral bar unit 20 will be described in detail. The latch 22 has slopes 22a and 22b on its left and right upper surfaces, respectively, and is trapezoidal in shape with its upper side shorter than its lower side. The upper and lower sides extend along the left-right direction of the housing 24. In FIG. 4(a), in the engaged position, the latch 22 is engaged with the engaging portion 11 at the engaging end 22c. The engaging surface of the engaging end 22c of the latch 22 faces the engaged surface of the engaging portion 11. In other words, in FIG. 4(a), the monitor unit 10 and the peripheral bar unit 20 are connected. The engaged surface of the engaging portion 11 is configured such that when a force (e.g., see force F) is applied to separate the peripheral bar unit 20 from the monitor unit 10, a force is applied to the latch 22 that urges the latch 22 outward. Furthermore, when the monitor unit 10 and the peripheral bar unit 20 are pulled in a direction that separates them, the engagement of the latch 22 is unlikely to be released.

[0017] Then, as shown in FIG. 4(b), the latch 22, which is pushed toward the inside of the housing 24, moves from the engaged position toward disengagement and abuts against the rib 12 provided on the monitor unit 10. At this time, the lower side of the right inclined surface 22b of the latch 22 abuts against the rib 12. Further, as a force of arrow F is applied to the latch 22, the abutting portion between the right inclined surface 22b of the latch 22 and the rib 12 moves toward the upper side of the inclined surface 22b. As a result, as shown in FIG. 4(c), the latch 22 moves downward. As a result, the left engagement piece of the latch 22 (e.g., the lower side of the left inclined surface 22a of the latch 22) is positioned below the engagement surface of the engagement portion 11 of the monitor unit 10. In other words, the monitor unit 10 and the peripheral bar unit 20 move away from each other, that is, the peripheral bar unit 20 moves downward relative to the monitor unit 10. However, in the state shown in Fig. 4(c), the monitor unit 10 and the peripheral bar unit 20 are not completely separated. Fig. 4(c) shows a state in which the force indicated by arrow F is at its maximum on the latch 22, and the biasing spring BN is in its most compressed state. It is also possible to omit Figs. 4(d) and 4(e) and configure the monitor unit 10 and the peripheral bar unit 20 to be completely separated in the state shown in Fig. 4(c).

[0018] Next, after the state shown in FIG. 4(c), the force of arrow F is released, resulting in the state shown in FIG. 4(d). From now on, the latch 22 moves leftward due to the force of spring BN, so that the engaging portion 11 comes into contact with the lower side of the slope 22a on the left side of the latch 22. Then, as the force of spring BN continues to be applied, the latch 22 continues to move, and the contact portion between the engaging portion 11 and the slope 22a gradually shifts to the upper side of the slope 22a on the left side of the latch 22. As a result, the monitor unit 10 and the peripheral bar unit 20 are detached, as shown in FIG. 4(e).

[0019] In this electronic device 1, which allows the monitor unit 10 and peripheral bar unit 20 to be detachably connected, the peripheral bar unit 20 has a latch 22 with slopes 22a and 22b at its two left and right ends, and the monitor unit 10 has an engagement portion 11 that engages with one of the left and right engagement ends 22c (outside in FIG. 4) of the latch 22, and a rib 12 that is located at the other end (inside in FIG. 4) of the latch 22 and faces the engagement portion 11. The latch 22 is biased by a spring BN and is movable. As shown in FIGS. 3 and 4(a), when the monitor unit 10 and peripheral bar unit 20 are connected, the latch 22 is located between the engagement portion 11 and the rib 12.

[0020] Furthermore, when the monitor unit 10 and the peripheral bar unit 20 are detached, the latch 22 moves inward of the peripheral bar unit 20 in the left-right direction due to an inward force acting on the spring BN, causing the inclined surface 22b provided at the inner end of the latch 22 to abut against the end (lower end) of the rib 12. The peripheral bar unit 20 then moves in a direction away from the monitor unit 10. Next, when the latch 22 moves outward of the peripheral bar unit 20 in the left-right direction, the inclined surface 22a on the outer side of the latch 22 abuts against the engaging portion 11, the peripheral bar unit 20 moves in a direction away from the monitor unit 10. Note that in the above, the inward and outward directions may be reversed. Also, the spring BN is not necessarily required.

[0021] 3. Connection between the monitor unit 10 and the peripheral bar unit 20 Next, a description will be given of the connection between the monitor unit 10 and the peripheral bar unit 20. Fig. 5 is a diagram showing the monitor unit and the peripheral bar unit when not connected.

[0022] As shown in Figure 5, when the monitor unit 10 and peripheral bar unit 20 are not connected, the connection portion 13 and the connection portion 23 are naturally not connected, and the latch 22 and the engagement portion 11 are not engaged. From the state of Figure 5, by pushing the peripheral bar unit 20 toward the monitor unit 10 and sequentially transitioning the state from the state of Figure 4(e) to the state of Figure 4(a), the monitor unit 10 and the peripheral bar unit 20 can be connected as shown in Figure 3. However, because the latch 22 is biased to the left by the spring BN, the engagement portion 11 and the latch 22 do not separate as shown in Figure 4(c).

[0023] 4. Measures against unexpected unlocking Next, measures against unexpected unlocking of the electronic device 1 will be described. Fig. 6 is a diagram showing the relationship between a plurality of through holes and a tool, with (a) being a perspective view and (b) being an explanatory diagram. Figs. 7(a) and 7(b) are diagrams showing the pressing portion of the latch. Fig. 8 is a diagram showing the positional relationship between a plurality of through holes. Fig. 9 is a diagram showing a plurality of through holes and a stopper.

[0024] As shown in FIG. 6(a), when a tool 30 presses the latch 22 through an access hole 21 provided in the housing 24, the latch 22 moves, and the monitor unit 10 and the peripheral bar unit 20 are separated.

[0025] As shown in FIG. 6(b), the tool 30 presses the pressing portion 25 of the latch 22. The pressing portion 25 is provided with a pressing portion through-hole 26. Therefore, even if a rod-shaped member narrower than the width of the pressing portion through-hole 26 is used to press the latch 22, it will not be able to do so. A rod-shaped member wider than the width of the access hole 21 cannot be inserted into the access hole 21, and therefore cannot press the latch 22. That is, as shown in FIG. 6(b), the width X1 of the dedicated tool 30 is narrower than the width X2 of the access hole 21 and wider than the width X4 of the pressing portion through-hole 26, so the pressing portion 25 of the latch 22 can be pressed. The width of the pressing portion through-hole 26 refers to the minimum width, such as the diameter if the inner peripheral shape of the pressing portion through-hole 26 is circular, or the length of one side if the inner peripheral shape of the pressing portion through-hole 26 is square. The width of the tool 30 refers to the maximum width of its cross section. Depending on the shapes of the tool 30, the access hole 21, and the pusher through-hole 26, the width may not necessarily be the minimum width. The width may also be referred to as the size or cross-sectional area. What is important is that the tool 30 can pass through the access hole 21 but cannot pass through the pusher through-hole 26, allowing the tool 30 to press the pusher 25. In this example, the tool 30 is a 1 / 16-inch hex wrench with a width of 1.59 mm. The width X2 of the access hole 21 is 1.80 mm, and the width X4 of the pusher through-hole 26 is 1.55 mm. Generally, the width X4 of the pusher through-hole 26 should be 80 to 90% of the width X2 of the access hole 21. The closer the width X4 of the pusher through-hole 26 and the width X2 of the access hole 21 are to each other (e.g., 95%), the more restrictive the rod-shaped members that can press the pusher 25 can be. On the other hand, the greater the difference between the width X4 of the push portion through-hole 26 and the width X2 of the access hole 21 (for example, 70%), the less strict the size of the rod-shaped member needs to be controlled, and the rod-shaped member can continue to be used even if it is slightly chipped. Note that the tool 30 does not need to be rod-shaped overall. It is sufficient if it can be inserted into the access hole 21 and the part that pushes the latch 22 is substantially rod-shaped. The rod-shaped part may also be curved.

[0026] It is preferable that the access hole 21 and the push portion through-hole 26 are formed along the same axis. This axis should preferably be aligned with the movement direction of the latch 22, as shown by the dotted line in Figure 6(b). Note that "along" includes being parallel and approximately parallel (within an error of about 15 degrees).

[0027] That is, the electronic device 1 includes a connection device that can detachably connect a first unit (peripheral bar unit 20) and a second unit (monitor unit 10), and the electronic device 1 includes a connection device that can detachably connect the first unit and the second unit, the connection device including a housing 24 of the peripheral bar unit 20, a latch 22 provided inside the housing 24 of the peripheral bar unit 20 and having a pressing portion 25, and an engagement portion 11 provided on the monitor unit 10 that engages with the latch 22, the latch 22 being movable when the pressing portion 25 is pressed, a first through-hole (access hole 21) being provided in the housing 24 along a predetermined direction (for example, the direction of the dotted line in FIG. 6(b)), a second through-hole (pressing portion through-hole 26) being provided in the pressing portion 25 along the predetermined direction, and the width of the access hole 21 being greater than the width of the pressing portion through-hole 26. This can improve the effect of preventing unexpected disconnection in a connection structure that allows multiple units to be detachably connected.

[0028] 6(b), the monitor unit 10 and the peripheral bar unit 20 are separated by pressing the pressing portion 25 in a predetermined direction (for example, the direction of the dotted line in FIG. 6(b)). The direction in which the pressing portion 25 is pressed and the directions of the access hole 21 and the pressing portion through-hole 26 are aligned, so that the monitor unit 10 and the peripheral bar unit 20 can be smoothly separated.

[0029] Furthermore, latch 22 can be moved in a predetermined direction (for example, the direction of the dotted line in FIG. 6(b)) when pressing portion 25 of latch 22 with tool 30, which is a rod-shaped instrument, passing through access hole 21. That is, the width of tool 30 is narrower than the width of access hole 21.

[0030] Furthermore, the width of tool 30 is narrower than the width of access hole 21 and wider than the width of pusher through-hole 26. This allows tool 30 to press pusher 25, but a rod-shaped member wider than access hole 21 or narrower than pusher through-hole 26 cannot press pusher 25.

[0031] As shown in FIGS. 6(b) and 7, the pusher through-hole 26 of the pusher 25 has a funnel-like shape. In other words, in FIG. 6(b), the pusher through-hole 26 has a maximum width X3 on the outside of the housing 24 along the axis (the direction of the dotted line) and a minimum width X4 on the inside of the housing 24 along the axis. The width of the tool 30 is narrower than X3 and wider than X4. As a result, the tool 30 can firmly press the pusher 25 inside the pusher through-hole 26. The pusher through-hole 26 is also funnel-shaped, and its cross-sectional width decreases from the outside to the inside in the left-right direction of the housing 24 along the axis. In other words, the pusher through-hole 26 has a larger width on the side closer to the access hole 21 and decreases as it moves away from the access hole 21.

[0032] Therefore, although it was stated above that "the width of the access hole 21 is greater than the width of the pressing portion through-hole 26," the width of the pressing portion through-hole 26 referred to here may be the width X4 of the inner cross section of the pressing portion through-hole 26 in a predetermined axis direction (for example, the direction of the dotted line in FIG. 6(b)). This is because the width of the tool 30 is greater than the smallest cross section of the pressing portion through-hole 26, allowing the tool 30 to press the pressing portion 25.

[0033] Furthermore, it is preferable that the access hole 21 and the pusher through-hole 26 are positioned parallel to the left-right direction of the housing 24. This allows the rod-shaped tool 30 to intuitively push the pusher 25 in approximately the same direction as the left-right direction of the housing 24. Furthermore, as shown in FIG. 9 , the width X3 of the outer cross section of the pusher through-hole 26 may be larger than the width X2 of the access hole 21. It is only necessary that the minimum width X4 of the pusher through-hole 26 is smaller than the width X1 of the tool 30 and the width X2 of the access hole 21.

[0034] 5. About the stopper Next, the stopper 16 will be described. FIG. 9 is a cross-sectional view showing the positional relationship between the multiple through-holes and the stopper 16. The stopper 16 is provided in the peripheral bar unit 20 at a position inside the housing 24 relative to the pusher 25. For example, if a rod-shaped object thinner than the minimum width X4 of the pusher through-hole 26 is inserted through the access hole 21, it may pass through the pusher through-hole 26 because it is thinner than the minimum width X4. In this case, the toothpick may get stuck inside the peripheral bar unit 20. To prevent this, the peripheral bar unit 20 has a stopper 16 located further inside the housing 24 relative to the pusher through-hole 26, thereby preventing a thin rod-shaped object from getting stuck inside the peripheral bar unit 20. The surface area of ​​the stopper 16 is preferably larger than the surface area of ​​the pusher through-hole 26. This surface of the stopper 16 is a surface that prevents the entry of objects such as toothpicks.
