Description

  The present invention relates to an improved technology for an anti-theft mechanism provided in a suitcase.

  As a theft prevention mechanism for a suitcase, various structures have been proposed (for example, see Patent Document 1).

  As shown in FIG. 1 of Patent Literature 1, the anti-theft mechanism (10) (the number in parentheses indicates the code described in Patent Literature 1. The same applies hereinafter) includes a transmitting unit (20) and a receiving unit (30). It consists of. The transmitting unit (20) is carried by the user, and the receiving unit (30) is left (inserted) in a suitcase (Patent Document 1, paragraph number 0022). The receiving unit (30) has a built-in vibration sensor in addition to the alarm element (Patent Document 1, paragraph 0011).

When the receiving unit (30) is separated from the transmitting unit (20) carried by the user by a certain distance, an alarm starts to sound (see FIG. 4 of Patent Document 1). That is, when the suitcase is separated from the user by a certain distance, an abnormality is displayed by the sound signal, and theft can be prevented.
In addition, even when the suitcase is within a certain distance, when vibration is applied to the suitcase, the vibration sensor detects an abnormality, the abnormal state is recognized, and theft can be prevented.

The antitheft mechanism (10) of Patent Document 1 having such advantages has the following disadvantages.
First, it is sometimes forgotten to put the receiving unit (30) into the suitcase. If you forget, theft is not prevented.

  In addition, since the suitcase has good hermeticity, acoustic energy generated by the alarm element of the receiving unit (30) in the suitcase is attenuated while passing through the suitcase shell. A strong alarm element is required to compensate for the attenuation, but a strong battery is required, and the receiving unit (30) is large and heavy.

  While the weight of the suitcase is required to be reduced, it is not preferable that the receiving unit (30) is heavy. Furthermore, since a vibration sensor is essential, the receiving unit (30) becomes expensive.

  A theft prevention mechanism having a structure that can eliminate these disadvantages is desired.

It is a perspective view of the suitcase provided with the anti-theft mechanism concerning the present invention. It is a front view of a theft prevention mechanism. It is sectional drawing of a theft prevention mechanism. It is a figure which shows a lining. It is a perspective view which shows the example of a change of a suitcase. It is sectional drawing of the anti-theft mechanism concerning a modification.

  An embodiment of the present invention will be described below with reference to the accompanying drawings. The drawings should be viewed in the direction of reference numerals.

  As shown in FIG. 1, the suitcase 10 includes a main body shell 11 that is a main body of a storage case, a lid shell 12 that closes an opening of the main body shell 11, a telescopic handle 13 that is provided to be able to be pulled out from the main body shell 11, It has two casters 14 provided at the bottom of the shell 11 (one at the right back is not visible) and two casters 15 provided at the bottom of the lid shell 12. A non-stretchable handle 16 used when the user lifts the suitcase 10 by hand is also provided.

In this example, an anti-theft mechanism 20 is provided at the center of the lid shell 12.
The anti-theft mechanism 20 can be provided on the main body shell 11.
The anti-theft mechanism 20 is operated by the portable terminal 18 carried by the user of the suitcase 10.

  The mobile terminal 18 has built-in application software for operating the anti-theft mechanism 20. The application software monitors the intensity of radio waves emitted from the anti-theft mechanism 20. As the distance between the portable terminal 18 and the anti-theft mechanism 20 increases, the radio wave weakens.

By operating the mobile terminal 18, the user can perform the operation described below.
-Start-up operation of the anti-theft mechanism 20 (switches the hibernation state to the operation state. After startup, battery consumption increases)
In the operating state, when the suitcase 10 and the portable terminal 18 are separated from each other by a predetermined distance (for example, 5 m) or more, the anti-theft mechanism 20 generates a warning sound as an abnormal display.
In the operating state, if the distance between the suitcase 10 and the portable terminal 18 is within a certain distance (for example, 5 m), the anti-theft mechanism 20 does not emit a warning sound.
・ Operation to artificially silence the warning sound.
・ Display the remaining battery power.
-Display that prompts for battery replacement.
Stop operation of the anti-theft mechanism 20 (switches the operation state to the sleep state. The sleep state is entered and the battery consumption is minimized).

As shown in FIG. 2, when the lid shell 12 is viewed from the outside, a circular cover member 30 can be seen.
The cover member 30 has a donut plate-shaped cover main body 31, a louver portion 32 that horizontally traverses the opening of the cover main body 31, and crosses these louver portions 32 to vertically extend the opening of the cover main body 31. It is a resin molded product or a light metal molded product having a transverse guard portion 33.

  As shown in FIG. 3, the anti-theft mechanism 20 includes a perforated plate 21 having a number of small holes formed in a metal plate or a resin plate, a sound generating piece 22 disposed behind the perforated plate 21, A holder plate 23 supporting the generating piece 22, a substrate 24, a battery holder portion 25 and a push button switch 26 mounted on the substrate 24, a battery 27 inserted into the battery holder portion 25, and a battery cover 28 24, and a screw 29B for fastening the back cover 29 to the cover member 30.

The sound generating piece 22 is a vibrating piece that vibrates at a high speed by receiving supply of electric energy such as a piezoelectric element.
The lid shell 12 has a recess 35 for accommodating the cover member 30, and has one through hole 36 at the center of the recess 35.
The cover member 30 is attached to the outside of the recess 35, and the perforated plate 21, the holder plate 23, the substrate 24, and the back cover 29 are stacked in this order inside the recess 35, and are collectively fastened with screws 29B.

These screws 29B can be turned from inside the suitcase 10. That is, since the screw 29B cannot be turned from outside the suitcase 10, the security is enhanced.
The anti-theft mechanism 20 having the above configuration is accommodated between the lid shell 12 and the lining 38.

  As shown in FIG. 4, a fastener 39 is provided on the inner lining 38. By opening the fastener 39, the battery cover 28 can be removed and the battery 27 can be replaced. Note that the fastener 39 is basically a linear fastener, but may be a surface fastener.

  The push button switch 26 is not normally operated. The push button switch 26 can be used to artificially stop the alarm sound only when it is difficult to perform a stop operation on the mobile terminal 18 (for example, when the mobile terminal 18 is not at hand but the alarm sound is to be stopped). Since the push button switch 26 cannot be operated from outside the suitcase 10, security is enhanced.

  When the suitcase 10 shown in FIG. 1 is relatively away from the mobile terminal 18 by a certain distance (for example, 5 m) or more, the sound generation piece 22 shown in FIG. 3 generates a warning sound. Since this warning sound passes through the hole of the perforated plate 21 and the through hole 36 of the lid shell 12, it is emitted to the outside with almost no attenuation.

If the anti-theft mechanism is put into the closed suitcase 10, the warning sound is greatly attenuated in the suitcase 10, and the warning effect is weakened.
In this regard, in the present invention, since the warning sound is hardly attenuated, the warning effect is enhanced.

In addition, since the cover shell 12 is provided with the through hole 36, there is a concern that rainwater may enter, but there is no problem because the louver portion 32 prevents rainwater from entering.
However, the louver part 32 is structurally fragile and deforms when hit by an obstacle. Therefore, the guard portion 33 is made to go out of the louver portion 32. Although an external obstacle hits the guard portion 33, there is no fear of reaching the louver portion 32.

  As shown in FIG. 1, the suitcase 10 has a circular cover member 30 at the center of the lid shell 12. Since the cover member 30 looks like a circular speaker, when a warning sound is emitted to the suitcase 10, it is notified to surrounding people that the anti-theft mechanism 20 is provided, and a warning effect is expected from this point as well.

There is a view that the circular cover member 30 becomes a one-point accessory and can be differentiated from an existing suitcase.
This perspective can be supported by some suitcase users. On the other hand, there are users who prefer a safe (inconspicuous) appearance suitcase without one-point accessories. Therefore, a suitcase 10B close to a safe suitcase will be described with reference to FIGS.

  As shown in FIG. 5, in the suitcase 10B, a circular anti-theft mechanism 20B is provided at the center of the lid shell 12. The same reference numerals as in FIG. 1 are used for the same components as those in FIG.

  As shown in FIG. 6, the anti-theft mechanism 20B includes a plurality of through holes 36 provided directly in the lid shell 12, a sound generating piece 22, a holder plate 23, a substrate 24, a battery 27, and a push button switch 26. , A back cover 29 and a screw 29B.

  An extremely shallow concave portion 35 is provided in the lid shell 12, and a small through hole 36 is provided in the concave portion 35. The water-permeable and breathable film 41 is attached so as to cover these through holes 36. The water-permeable and breathable film 41 is a film in which a resin film is formed with numerous micropores having a diameter larger than that of air molecules and smaller than water molecules. The water-impermeable permeable film 41 is basically attached to the outer surface of the shell 12, but may be attached to the inner surface of the shell 12 to prevent peeling.

  In FIG. 5, by matching the color of the lid shell 12 with the color of the water-permeable and breathable film 41, a safe suitcase 10B can be obtained. It should be noted that it is possible to improve the discriminability by making the water-permeable and air-permeable film 41 a different color from the color of the lid shell 12.

  Note that the suitcases 10 and 10B are suitcases in a broad sense including a square bag and a trunk.

  INDUSTRIAL APPLICABILITY The present invention is suitable for a suitcase used in an area where theft occurs frequently.
