Description

[Detailed Description of the Invention] The present invention relates to a locking device for preventing theft of portable equipment.

For example, since portable devices such as small communication devices are easy to transport, there is a risk of theft when they are stored, and therefore a device is required to prevent theft.

1 and 2 are perspective views showing a conventional anti-theft locking device for storing such a portable device, in which 1 is the portable device, and 2 is a handle provided on the portable device 1. , 3 are feet provided at the four corners of the bottom of the portable device 1. Reference numeral 4 denotes a fixed case shaped to accommodate the portable device 1, and has mounting feet 5 formed on both sides of the bottom, and the mounting feet 5 are fixed onto a fixed base 6 with screws 7. Reference numeral 8 is welded to a mounting bracket 9 fixed to the front of the fixed housing with a catch clip. 10 is a chain and 11 is a lock.

This configuration includes a portable device 1 as shown in FIG.
into the fixed housing 4, fold the handle 2 forward, hook the catch clip 8 attached to the fixed housing 4 onto the handle 2, and fix it. Then, pass the chain 10 through the handle 2 and the mounting bracket 9. A loop is formed and both ends of the chain 10 are connected with a lock 11 so that the portable device 1 cannot be removed from the fixed base 6 during storage.

However, since these conventional anti-theft locking devices use a chain and a lock, the chain must be attached or removed each time the lock is locked or unlocked. Therefore, the operation is complicated, and it is also troublesome to dispose of the chain and lock after removing the portable device from the fixed casing.Furthermore, if the chain is cut or the screws of the mounting foot are removed, The drawback was that it had no anti-theft effect.

The purpose of the present invention is to solve these drawbacks, and for this reason, the mounting feet of the fixed casing in which the portable device is placed are screwed onto the fixed base, and in addition to this, the mounting feet are also used to lift up from the fixed base. The bottom plate of the fixed housing is fixed to the fixing base by a fixing screw passed through the top surface of the bottom plate, and a lever having an engagement notch at the tip that engages with the flanged pin is attached to the bottom of the bottom plate by a support shaft. The lever is rotatably attached, and the tip of the lever is inserted into the upper surface of the bottom plate through a notch provided in the bottom plate. A rotary lock is attached to the outer wall surface of the fixed casing, and the rotary lock is connected to the rear part of the lever, and both ends of a tension spring directed from the tip of the lever toward the rear,
By configuring the lever to be engaged with a locking portion provided on the fixed casing so as to be located on a line connecting the spindle and the rotary lock, the key can be inserted into the keyhole of the rotary lock and turned. The locking and unlocking operations can be easily performed using only a hand, and the theft of portable equipment can be reliably prevented, and the tactile sensation when turning the key is clear, allowing confirmation of locking or unlocking. It is characterized by being made possible.

To explain the following with reference to the drawings, Fig. 3 is a perspective view showing an embodiment of the present invention in a state before locking, Fig. 4 is a perspective view showing a state after locking, and Fig. 5 is a side of the main part of Fig. 4. The sectional view and FIG. 6 are bottom views of essential parts of FIG. 4, and in these figures, parts equivalent to those in FIGS. 1 and 2 are designated by the same reference numerals, and their explanations will be omitted.
12 is a pin with a flange, which is provided on the bottom surface of the portable device 1. The flanged pin 12 may have a length equal to or slightly shorter than the leg 3 provided on the bottom of the portable device 1. 1
3 is a bottom plate of the fixed housing 4, and the bottom plate 13 has a notch 1
4 is provided so that the flanged pin 12 is positioned above the notch 14 when the portable device 1 is placed in the fixed housing 4. This bottom plate 13
As shown in FIG. 3, the fixed housing 4 is fixed to the fixed base 6 by fixing screws 15 passed through the top surface thereof. Therefore, in this embodiment, the fixed housing 4 has the mounting legs 5 and the bottom plate 13 fixed to the fixed base 4. It has a structure. 16 is a rotary lock, which has a lock cover 17;
7 is fixed to the outer wall surface of the fixed casing 4 by a set screw 18 passed through the inner wall surface of the fixed casing 4. A rotary plate 19 that rotates integrally with the rotary lock 16 is attached to the rotary lock 16, and a connecting pin 20 is formed on the rotary plate 19. Reference numeral 21 denotes a key, and the key 21 is inserted into the keyhole of the rotary lock 16 to rotate the rotary lock 16.
Reference numeral 22 denotes a lever, which is attached to the bottom plate 13 of the fixed housing 4 so as to rotate around a support shaft 23. The tip of this lever 22 is bent so as to enter the inside of the fixed housing 4 from the notch 14 of the bottom plate 13, and the bent part has a flanged pin 12 provided on the bottom of the portable device 1. An engagement notch 24 for engagement is provided, and the rear part of the lever 22 is connected to the fixed housing 4.
It penetrates the wall surface of the lock cover 17 and enters the lock cover 17. A connecting notch 25 is provided at the rear portion of the lever 22, and the lever 22 is connected to the rotary lock 16 by loosely fitting the connecting pin 20 of the rotary plate 19 into the connecting notch 25. Reference numeral 26 denotes a tension spring, one end of which is engaged with a cut-out provided at the tip of the lever 22, and the other end of which is attached to the wall of the fixed housing 4 so as to be located on a line connecting the support shaft 23 and the rotary lock 16. It is locked in a locking part such as a hole provided.

Next, the operation of the above-described configuration will be explained. First, the third
As shown in the figure, the portable device 1 is placed in the fixed casing 4, the handle 2 is folded forward, and the catch clip 8 attached to the fixed casing 4 is hooked onto the handle 2 to fix it. Then, insert the key 21 into the keyhole of the rotary lock 16 as shown in FIG.
When the lever 22 is rotated in the direction of the arrow A, the lever 22 rotates around the support shaft 23, thereby moving the tip of the lever 23 from the position C to the position E, and the lever 23 is moved to the engagement position. The notch 24 engages with the flanged pin 12 provided on the portable device 1, and the portable device 1 is locked. Even if you remove the screws 7 fixing the mounting feet 5 of the fixed case 4 to the fixed base 6 in this state and try to remove the portable device 1 along with the fixed case 4 from the fixed base 6, the fixed case 4 bottom plate 1
3 is fixed by a fixing screw 15, and since this fixing screw 15 is tightened from the top surface of the bottom plate 13, it cannot be removed unless the portable device 1 is taken out from the fixed casing 4. Theft of the portable device 1 can be reliably prevented.

Next, to release the locked state shown in FIG. 4 and take out the portable device 1 from the fixed housing 4, rotate the rotary lock 16 with the key 21 in the direction of arrow B shown in FIG. The tip of is from position E to position C.
, the lever 22 touches the flanged pin 12.
It comes off and the lock is released. Therefore, by removing the catch clip 8 from the handle 2, the portable device 1 can be taken out from the fixed housing 4.

Note that when the lever 22 is rotated by the key 21, the tip of the lever 22 passes through an extension point D of a line connecting the support shaft 23, which is the center of rotation, and the locking end of the tension spring 26 on the fixed casing side. Since the key 21 is automatically moved to the position E or the position C by the tensile force of the tension spring 26, there is a clear feeling when the key 21 is turned, so that locking or unlocking can be confirmed.

Further, the catch clip 8 is preferably provided when the portable device 1 is a vibrating device, but is not necessarily necessary in the present invention.

As explained above, the present invention provides a flanged pin on the bottom surface of a portable device, fixes the bottom plate of a fixed casing to a fixed base with a fixing screw, and provides a rotatable device that engages with the flanged pin on the bottom plate. A lever is attached, and a rotary lock connected to the lever is attached to the outer wall surface of the fixed casing, and the rotary lock is rotated with a key so that the lever engages with the flanged pin and locks. Since the tip of the lever is inserted into the bottom plate through the notch in the bottom plate, there is an effect that the theft of the portable device can be reliably prevented. Further, since locking and unlocking can be performed only by operating a key, there is an advantage that the operation is easy and that it can be applied to conventional portable equipment without changing the shape. Furthermore, both ends of the lever and the spring are engaged with a locking portion provided on the fixed casing so as to be located on a line connecting the spindle and the rotary lock that attach the lever to the bottom plate of the fixed casing, When the lever is rotated together with the lock using the key, when the tip of the lever passes through the extension point D of the line connecting the spindle, which is the center of rotation, and the locking end of the tension spring on the fixed casing side, the tension of the tension spring increases. Since the key is automatically moved to position E or position C by force, there is a clear feeling when turning the key, which also has the effect of making it possible to confirm whether the key is locked or unlocked.
