Description

  The present invention relates to an electronic device having a lock plate to which an antitheft lock device called a Kensington lock or a security cable is connected.

  A portable electronic device such as a portable computer has a security lock slot. The slot is for connecting an anti-theft locking device called a Kensington lock or a security cable, and is formed on a peripheral wall of a casing that is an outer shell of the electronic device.

  The lock device includes a tough wire and a lock cylinder fixed to one end of the wire. The lock cylinder has a hook that can be inserted into a slot of the housing. The scissors can be rotated to a locked position orthogonal to the slot by using a lock key, and the scissors are caught on the peripheral wall of the casing by this rotation.

  For this reason, after winding the wire around a fixed object such as an office desk, the wire between the electronic device and the fixed object is inserted by inserting the collar of the lock cylinder into the slot of the housing and rotating it to the locked position. You can keep it connected. Therefore, free movement and take-out of the electronic device are restricted, and the electronic device can be prevented from being stolen.

  By the way, in recent electronic devices, in order to increase the commercial value and portability, the thinning of the casing has been strengthened. In an electronic device that seeks to reduce the thickness of the housing, it is difficult to secure a space for connecting a lock cylinder rod to the housing, and it may be difficult to connect the lock device.

  In order to improve this problem, for example, in the electronic device disclosed in Patent Document 1, a slide plate is disposed between the upper surface of the housing and the key top of the keyboard. The slide plate has an operation blocking portion at a position corresponding to each key. The slide plate is slidable between a first position where the operation blocking portion enters the space on the back side of the key and a second position where the operation blocking portion is positioned below the edge of the key.

  In a state where the slide plate is slid to the second position, one end portion of the slide plate penetrates the side surface of the housing and protrudes to the side of the housing. A through hole is formed at one end of the slide plate. The through-hole is for inserting a padlock latch and is close to the side of the housing. The padlock has a chain or wire for fixing to an object that cannot be easily moved, such as a desk.

  Therefore, the padlock can be attached to the slide plate by sliding the slide plate from the first position to the second position and pulling out one end portion of the slide plate in which the through hole is formed from the housing. Therefore, a padlock can be attached to this casing without difficulty even if the casing is made thinner.

JP 2000-56857 A

  According to Patent Document 1, when the slide plate to which the padlock is attached is slid from the second position toward the first position, the padlock contacts the side surface of the housing. Due to this contact, the slide plate cannot be slid to the first position, and the key is locked in an inoperable state by the operation blocking portion of the slide plate.

  However, in a configuration in which sliding of the slide plate is restricted by bringing the padlock into contact with the side surface of the housing, the side surface of the housing in contact with the padlock is likely to be damaged. For this reason, the appearance of the electronic device is deteriorated.

  An object of the present invention is to obtain an electronic device that can easily connect an anti-theft locking device to a casing whose thickness has been strengthened and can prevent damage to the peripheral wall of the casing.

In order to achieve the above object, an electronic device according to one aspect of the present invention includes:
A housing having a peripheral wall in which an opening is formed;
The first position stored in the case and the second position protruding out of the case through the opening are supported by the case so as to be slidable. A lock plate having a keyhole to which a lock device for theft prevention is connected to a portion exposed to the outside of the housing when slid;
A stopper mechanism that holds the lock plate in the second position when the lock plate is slid to at least the second position;
The lock device is connected to the key hole of the lock plate that has been slid to the second position, thereby preventing the housing from being stolen using the lock device.

  According to the present invention, by sliding the lock plate to the second position, an antitheft lock device can be connected to the lock plate without difficulty. Moreover, the lock plate can be held in the second position without bringing the locking device into contact with the peripheral wall of the casing, and damage to the peripheral wall of the casing can be prevented.

  As shown in FIGS. 4 to 6, the housing 4 of the computer main body 2 includes a lock plate 12. The lock plate 12 is composed of a flat square metal plate. The lock plate 12 has a pair of side edges 13a and 13b, one end edge 13c connecting one end of the side edges 13a and 13b, and the other end edge 13d connecting the other end of the side edges 13a and 13b. ing. The side edges 13 a and 13 b extend parallel to each other along the width direction of the housing 4.

  Further, the lock plate 12 has a first long hole 15a and a second long hole 15b. The first and second elongated holes 15a and 15b are arranged in parallel with each other along the side edges 13a and 13b of the lock plate 12.

  The lock plate 12 is integrally incorporated in the right side portion of the rear end of the first housing element 6. 5 to 7 show the support structure of the lock plate 12. As shown in FIGS. 6 and 8, the bottom wall 4a of the first housing element 6 includes a pair of guide walls 16a and 16b and a pair of guide rails 17a and 17b. The guide walls 16 a and 16 b stand from the inner surface of the bottom wall 4 a so as to extend in the width direction of the housing 4, and are arranged in parallel with a space between each other. One ends of the guide walls 16a and 16b are connected to the inner surface of the right side wall 4d.

  The right side wall 4d has an opening 18 that opens between the guide walls 16a and 16b. The opening 18 has a slit shape extending in the depth direction of the housing 4. The opening 18 opens from the right side of the housing 4 downward as the side wall 4d is curved.

  The guide rails 17a and 17b stand from the inner surface of the bottom wall 4a between the guide walls 16a and 16b. The guide rails 17a and 17b extend in the width direction of the housing 4 and are arranged in parallel with a space therebetween.

  Furthermore, a guide projection 19 and a boss portion 20 are formed on the inner surface of the bottom wall 4a. The guide protrusion 19 stands from the bottom wall 4a between the guide rails 17a and 17b. The boss portion 20 is adjacent to the guide protrusion 18 between the guide rails 17a and 17b. The boss portion 20 protrudes upward from the bottom wall 4 a and opens toward the lower side of the first housing element 6.

  The lock plate 12 is slidably mounted on the guide rails 17a and 17b between the guide walls 16a and 16b. Accordingly, the side edges 13a and 13b of the lock plate 12 are slidably in contact with the guide walls 16a and 16b, and the guide protrusion 19 is slidably inserted into the first long hole 15a of the lock plate 12. Yes.

  As shown in FIG. 6, the holding plate 22 is disposed on the lock plate 12. The holding plate 22 slidably holds the lock plate 12 between the guide rails 17a and 17b. The holding plate 22 has a columnar convex portion 23. The convex portion 23 protrudes from the lower surface of the holding plate 22 and is slidably fitted into the second long hole 15 b of the lock plate 12.

  Furthermore, the convex part 23 corresponds with the boss | hub part 20 which protrudes upwards from the bottom wall 4a. A screw 24 is inserted into the boss portion 20 from below the first housing element 6. The screw 24 is screwed into the convex portion 23 to fix the holding plate 22 to the first housing element 6.

  As a result, the lock plate 12 slides in the width direction of the housing 4 using the fitting portion between the first long hole 15a and the guide protrusion 19 and the fitting portion between the second long hole 15b and the convex portion 23 as a guide. It is supported by the housing 4 as possible. Specifically, the lock plate 12 is slidable between a first position stored inside the housing 4 and a second position protruding outside the housing 4 through the opening 18. Yes.

  FIG. 7 shows a state in which the lock plate 12 is slid to the first position. In the first position, the guide protrusion 19 hits one end of the first long hole 15a, and the convex portion 23 hits one end of the second long hole 15b.

  FIG. 9 shows a state in which the lock plate 12 is slid to the second position. In the second position, the guide protrusion 19 hits the other end of the first long hole 15a, and the convex portion 23 hits the other end of the second long hole 15b.

  Therefore, the sliding range of the lock plate 12 is determined by the lengths of the first and second long holes 15a and 15b.

  In a state where the lock plate 12 is slid to the first position, the other side edge 13d of the lock plate 12 is located at the opening 18. In a state where the lock plate 12 is slid to the second position, a region from the other end edge 13d of the lock plate 12 to the intermediate portion protrudes out of the housing 4 from the opening 18.

  As shown in FIGS. 5 and 7, a first recess 26 a and a second recess 26 b are formed on one side edge 13 a of the lock plate 12. The first recess 26 a and the second recess 26 b are separated from each other in the sliding direction of the lock plate 12.

  Further, a stopper mechanism 27 is installed on the bottom wall 4 a of the first housing element 6. The stopper mechanism 27 is for holding the lock plate 12 in the first position and the second position in cooperation with the first and second recesses 26a and 26b.

  As shown in FIGS. 6 and 7, the stopper mechanism 27 includes a slider 28 and a compression coil spring 29. The slider 28 is supported by the bottom wall 4a. The bottom wall 4a has a slide guide 30 as shown in FIG. 5 near one guide wall 16a. The slide guide 30 defines a guide groove 31 extending in the depth direction of the first housing element 6 so as to be orthogonal to the sliding direction of the lock plate 12.

  The guide groove 31 faces one side edge 13a of the lock plate 12 through a communication port 32 opened in one guide wall 16a. The communication port 32 matches the first recess 26a of the lock plate 12 when the lock plate 12 is slid to the first position. Similarly, the communication port 32 matches the second recess 26b of the lock plate 12 when the lock plate 12 is slid to the second position.

  The slider 28 is fitted in the guide groove 31 of the slide guide 30 and supported by the first housing element 6 so as to be able to linearly reciprocate in a direction orthogonal to the sliding direction of the lock plate 12. The slider 28 has a fitting portion 34 that fits into the first and second recesses 26 a and 26 b of the lock plate 12. The fitting portion 34 can enter and exit between the guide walls 16 a and 16 b through the communication port 32.

  As shown in FIG. 6, the fitting portion 34 has a slit 35 through which one side edge 13 a of the lock plate 12 passes, and the side edge 13 a of the lock plate 12 can be slid in the thickness direction of the lock plate 12. It is sandwiched. Further, the compression coil spring 29 is an example of an elastic member, and urges the slider 28 in a direction approaching the lock plate 12.

  Thereby, in a state where the lock plate 12 is slid to the first position, the fitting portion 34 of the slider 28 is elastically fitted to the first recess 26 a of the lock plate 12. By this fitting, the lock plate 12 is held in the first position.

  Similarly, when the lock plate 12 is slid to the second position, the fitting portion 34 of the slider 28 is elastically fitted to the second recess 26 b of the lock plate 12. By this fitting, the lock plate 12 is held in the second position.

  As shown in FIGS. 7 and 8, the first recess 26a has an edge 38 adjacent to the second recess 26b. The edge portion 38 is a portion that restricts the free movement of the lock plate 12 by striking the fitting portion 34 when the lock plate 12 is to be pulled out from the first position to the second position. The edge portion 38 is inclined in a direction approaching the second recessed portion 26b from the end of the first recessed portion 26a.

  As shown in FIGS. 8 and 9, the second recess 26b has an edge 39 adjacent to the first recess 26a. The edge portion 39 is a portion that restricts the free movement of the lock plate 12 by striking the fitting portion 34 when the lock plate 12 is to be pressed from the second position to the first position. The edge 39 is inclined in the direction approaching the first recess 26a from the end of the second recess 26b.

  As shown in FIGS. 1 and 3, the lock plate 12 includes a keyhole 41 for security lock. The key hole 41 is located next to the other end edge 13d of the lock plate 12, and is completely exposed outside the housing 4 when the lock plate 12 is slid to the second position. Further, when the lock plate 12 is slid to the first position, a part of the key hole 41 is exposed from the opening 18 toward the lower side of the housing 4 as shown in FIG.

  The key hole 41 is for connecting an anti-theft locking device 42 called a Kensington lock or a security cable, for example, and has an elongated opening shape parallel to the other end edge 13 d of the lock plate 12.

  As best shown in FIGS. 2 and 3, the locking device 42 includes a strong metal cable 43 that can withstand destructive work, and a lock cylinder 44 fixed to one end of the cable 43.

  The lock cylinder 44 has a T-shaped flange 45 that can be inserted into the keyhole 41. By operating a lock key 46 inserted into the lock cylinder 44, the collar 45 can be rotated by 90 ° between the unlock position and the lock position.

  Next, a procedure for connecting the lock device 42 to the portable computer 1 will be described.

  Prior to connecting the lock device 42 to the portable computer 1, the lock plate 12 is slid to the first position and stored inside the housing 4. In the first position, as shown in FIG. 7, the fitting portion 34 of the slider 28 is fitted into the first recess 26 a of the lock plate 12, thereby holding the lock plate 12 in the first position. . At the same time, as shown in FIG. 10, a part of the keyhole 41 of the lock plate 12 is exposed downward of the housing 4 through the opening 28.

  In order to slide the lock plate 12 from the first position to the second position, first, hook the tip of a tool such as a fingertip of a hand or a screwdriver into a part of the keyhole 41 exposed from the opening 18, The lock plate 12 is pulled out from the opening 18.

  At this time, since the edge portion 38 of the first recess 26 a hits the fitting portion 34 of the slider 28, a resistance that temporarily prevents the lock plate 12 from being pulled out is given. However, the edge portion 38 is inclined toward the second concave portion 26b located on the side opposite to the pulling direction of the lock plate 12.

  For this reason, if the lock plate 12 is pulled strongly when the edge 38 hits the fitting part 34, the fitting part 34 resists the urging force of the compression coil spring 29 as the edge 38 is inclined. It is pushed out from the recess 26a.

  Accordingly, the fitting of the fitting portion 34 to the first recess 26a is automatically released following the pulling operation of the lock plate 12. Therefore, the lock plate 12 can be easily slid from the first position toward the second position.

  As shown in FIG. 9, when the lock plate 12 reaches the second position, the second concave portion 26b of the lock plate 12 faces the communication port 32, and the fitting portion 34 of the slider 28 becomes the second concave portion 26b. Mating. By this fitting, the lock plate 12 is held in the second position.

  In a state where the lock plate 12 is slid to the second position, the end of the lock plate 12 having the keyhole 41 protrudes to the side of the housing 4. Therefore, the collar 45 of the lock device 42 can be inserted into the key hole 41 from above the lock plate 12.

  After the collar 45 is inserted into the key hole 41, when the collar 45 is rotated from the unlocked position to the locked position, the collar 45 is caught in the lock plate 12 in a direction orthogonal to the key hole 41. As a result, the lock cylinder 44 is connected to the lock plate 12.

  Therefore, after the cable 43 is wound around a fixed object that is difficult to move, such as an office desk, the portable computer 1 is fixed by connecting the collar 45 of the lock cylinder 44 to the lock plate 12 in the above-described procedure. Can be tied to things. Thereby, the free take-out and movement of the portable computer 1 are restricted, and the theft of the portable computer 1 can be prevented.

  As shown in FIG. 2, in a state where the lock cylinder 44 is connected to the lock plate 12, the lock cylinder 44 stands on the lock plate 12 so that its axis is along the vertical direction. Further, a predetermined gap g is secured between the outer peripheral surface of the lock cylinder 44 and the side wall 4 d of the housing 4. The presence of this gap g prevents interference between the lock cylinder 44 and the housing 4.

  In other words, the lock plate 12 is pulled out to the side of the housing 4 to a position where the lock cylinder 44 connected to the keyhole 45 is not in contact with the side wall 4 d of the housing 4.

  On the other hand, when the collar 45 is rotated from the lock position to the lock release position, the lock device 42 can be removed from the lock plate 12. In a state where the lock device 42 is removed from the lock plate 12, the lock plate 12 is pushed from the second position toward the first position so that the lock plate 12 does not get in the way.

  At this time, as shown in FIG. 9, the edge 39 of the second recess 26 b hits the fitting portion 34 of the slider 28, so that a resistance that temporarily prevents the lock plate 12 from being pushed is given. However, the edge 39 is inclined toward the first recess 26 a located on the opposite side to the pushing direction of the lock plate 12.

  For this reason, when the lock plate 12 is pushed in strongly when the edge 39 hits the fitting portion 34, the fitting portion 34 resists the urging force of the compression coil spring 29 as the edge 39 is inclined. It is pushed out from the recess 26b.

  Thereby, the fitting of the fitting portion 34 to the second recess 26b is automatically released following the pushing operation of the lock plate 12. Therefore, the lock plate 12 can be easily slid from the second position toward the first position.

  When the lock plate 12 reaches the first position, the fitting portion 34 of the slider 28 is fitted into the first recess 26a. By this fitting, the lock plate 12 is held in the first position and stored inside the housing 4.

  According to such a configuration, the lock device 42 can be connected to the key hole 41 by pulling the end of the lock plate 12 having the key hole 41 out of the housing 4. Therefore, for example, even when the thickness of the housing 4 is strengthened and the thickness of the housing 4 is smaller than the outer diameter of the lock cylinder 44, the lock cylinder 44 can be connected to the housing 4 without difficulty. .

  Further, when the lock plate 12 is not used, the lock plate 12 can be stored in the housing 4 by sliding the lock plate 12 to the first position. Therefore, the lock plate 12 does not get in the way and the appearance of the portable computer 1 is convenient.

  In addition, according to the above configuration, when the lock plate 12 is slid to the second position, the fitting portion 34 of the slider 28 is fitted into the second recess 26b of the lock plate 12, and the lock plate 12 is moved to the second position. Is held in the position. In addition, since there is a gap g between the lock cylinder 44 connected to the lock plate 12 and the housing 4, the positional relationship between the lock cylinder 44 and the housing 4 is kept constant.

  For this reason, the lock cylinder 44 and the side wall 4d of the housing 4 do not contact each other, and the housing 4 can be prevented from being damaged. Therefore, the appearance of the portable computer 1 can be maintained satisfactorily.

  According to the present embodiment, the fitting portion 34 of the slider 28 is fitted in the first recess 26 a of the lock plate 12, thereby holding the lock plate 12 in the first position. For this reason, for example, while the portable computer 1 is being carried, the lock plate 12 can be prevented from jumping out of the housing 4, and damage to the lock plate 12 can be avoided.

  At the same time, the fitting portion 34 of the slider 28 slidably sandwiches the side edge 13a of the lock plate 12 in which the first and second recesses 26a and 26b are formed. For this reason, the positional relationship between the fitting portion 34 and the lock plate 12 can always be maintained constant, and the fitting portion 34 and the first recess 26a and the fitting portion 34 and the second recess 26b are fitted. There is an advantage that can be performed accurately.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the invention.

  For example, the first recess for holding the lock plate in the first position may be omitted, and a magnet may be disposed in the housing instead of the first recess. The magnet attracts the lock plate when the lock plate is slid to the first position, and holds the lock plate in the first position.

  The lock plate is not limited to jumping out to the side of the casing, but may be projected to the front or rear of the casing.

  Further, the lock plate is not specified to slide between the first position and the second position, and is supported on the housing so as to be rotatable between the first position and the second position, for example. You may do it.

  By applying the present invention to a portable electronic device such as a portable computer, it is possible to contribute to a reduction in the thickness of the housing and to maintain a good appearance of the electronic device.
