  2. Description of the Related Art Conventionally, portable crime prevention devices having a housing with an alarm device having various structures and forms have been proposed.

  Such a security device is portable when the user puts it in a pocket or by attaching it to a bag or the like. When a danger is detected by a stranger on the road or the like, an alarm sound is generated when the operating piece is activated.

  In recent years, crimes targeting children have increased rapidly, and the need for portable security devices has improved. .

  For example, in the case of an elementary school student in the lower grades, if the security device can be hung on a school bag or the like, the security device is always present at the time of attending school, which is advantageous in terms of safety. However, when attacked by a thief or the like, there is a problem that it takes time to operate a security device suspended on a school bag or the like.

  The present invention provides a portable security device that solves the above-mentioned problems. As a means for the portable security device, the housing is sized to be placed on the user's wrist, and the housing is detachable from the user's wrist. The casing includes a switch that is opened and closed by a forward / backward movement of the operating piece, a driving unit that operates when the switch is closed, and a sounding unit that generates a sound by the driving unit. An alarm device is provided, and a pair of band insertion holes facing each other at a predetermined interval in the X-axis direction are provided on the mounting surface facing the wrist of the casing, and the wristband is inserted into the pair of band insertion holes. A band base portion that is detachably inserted, a band tail end portion that extends from one end of the band base portion and is provided with a ring at the tip end, and a band tip end portion that extends from the other end of the band base portion, the body's A hook-and-loop fastener is provided that is inserted from the side toward the outside and folded back so as to be detachably attached to the folded portion, so that the operating piece of the switch can move forward and backward in the X-axis direction. Is provided on the side surface of the housing.

  In the embodiment of the present invention, each of the pair of insertion holes is formed by a substantially gate-shaped gate frame provided on the mounting surface of the housing, and between the pair of gate frames, there is a circumference of the user's wrist. Ribs are provided with arc-shaped recesses that allow the surface to be received.

  According to the present invention, for example, when the user carries the crime prevention device 1 in a pocket, the wristband 3 can be removed and the housing 2 can be carried in a compact state. However, on the other hand, when the child's body is always provided as intended, there is an effect that the wristband 3 can be attached to the child's wrist.

  Since the wrist band 3 is provided with hook-and-loop fasteners 19a and 19b that are detachably engaged with each other in a state where the band tip portion 7c is inserted from the inside of the ring body 18 toward the outside and folded back, It can be fastened to the user's wrist without slack. In the fastened state, the pair of gate frames 12 and 12 are in contact with the surface of the wrist, but at the same time, the arcuate recess 16 of the rib 15 disposed therebetween is in contact with the surface of the wrist. Does not bite into the surface of the wrist and has an effect of being excellent in wearing feeling.

  By the way, the operation piece 7 can be advanced and retracted in the X-axis direction with the security device 1 attached to the wrist. That is, the X-axis direction for operating the operating piece 7 is arranged in a direction crossing the arm including the wrist. Accordingly, when operating the security device 1, it is only necessary to pick the operating piece 7 with the fingertip of the hand not wearing the security device and pull it in the X-axis direction intersecting the arm, which may cause an operation error. There is no such thing and the safety is high.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  The portable security device 1 includes a housing 2 that is sized to be placed on the user's wrist and a wristband 3 that is detachably mounted on the user's wrist. The housing 2 is appropriately formed from a synthetic resin, and the wristband 3 is formed in a tape shape from a knitted fabric.

  An alarm device 4 is built in the housing 2. The alarm device 4 can be a specific example as shown in FIG.

  For example, in the first embodiment shown in FIG. 3 (A), the switch 6 provided in the power supply circuit including the battery 5 is opened / closed by the forward / backward movement of the operating piece 7 and operates when the switch 6 is closed. The alarm device 4 is composed of a buzzer driving circuit 8a as a sounding device and a buzzer device 9a as a sounding device 9 sounded by the driving device 8.

  Further, in the case of the second embodiment shown in FIG. 3B, the alarm device 4 is opened and closed by the forward / backward movement of the operating piece 7 in the switch 6 provided in the power supply circuit including the battery 5. The driving means 8 that operates when the switch 6 is closed is composed of a synthesized sound storage means 8b and an electronic circuit 8c, outputs music and other electronic synthesized sounds, and a speaker 9b as a sounding means 9 via an amplifier 8d. An alarm device 4 that produces sound by ringing is configured.

  The housing 2 is preferably provided with a decorative outer shape and pattern such as animals and other characters preferred by children, flowers, etc., as shown in the figure.

  As shown in FIGS. 1B and 2A, the housing 2 has a pair of band insertion holes 11 facing the mounting surface 10 facing the wrist of the user (child) at a predetermined interval in the X-axis direction. 11 are provided. The band insertion holes 11 and 11 are formed by substantially gate-shaped gate frames 12 and 12 provided on the mounting surface 10 of the housing 2, respectively.

  A base portion 13 is formed between the pair of gate frames 12 and 12 so as to be lifted from the mounting surface 10, and the circular cap 14 is attached and detached through an arc-shaped concave portion provided in the base portion 13. The battery 5 is provided freely, and the battery 5 can be replaced by opening and closing the cap 14.

  A rib 15 extending in the X-axis direction is provided between the pair of gate frames 12 and 12 at a side portion of the base portion 13, and an edge portion of the rib 15 is a user's wrist. An arcuate concave portion 16 is formed that can receive the peripheral surface.

  Therefore, the housing 2 formed in this manner is provided on the side surface 2a of the housing so that the operating piece 7 that operates the switch 5 can be moved forward and backward in the X-axis direction. At this time, it is desirable to appropriately provide an operation auxiliary piece 20 such as an operation ring on the operation piece 7. Incidentally, the operating piece 7 can be pulled out from the housing 2, and when the user pulls out the operating piece 7 by grasping the operation assisting piece 20 with a fingertip, the switch 5 is closed and an alarm sound is generated. When the operating piece 7 is inserted again, the switch 5 is opened and the alarm sound is stopped. However, the operating piece 7 is configured to be freely retractable as described above, and is configured to be movable back and forth within a predetermined restricted range, generating an alarm sound when moving in the pulling direction, and alarming when moving in the pushing direction. You may comprise so that a sound may be stopped.

  The wristband 3 includes a band base portion 17a that is removably inserted into the pair of band insertion holes 11, 11, a band tail end portion 17b that extends from one end of the band base portion 17a and is provided with an annular body 18 at the tip, A band distal end portion 17c extending from the other end of the band base portion 17a. The band distal end portion 17c is inserted from the inner side toward the outer side of the ring body 18 and folded, and the folded portions are detachably connected to each other. Surface fasteners 19a and 19b to be worn are provided. In the case of the illustrated example, the hook-and-loop fastener 19a provided on the tip end side of the band tip portion 17c and the hook-and-loop fastener 19b adjacent thereto are arranged slightly spaced from each other, and the portion between the double-sided fasteners 19a and 19b. A foldable portion 21 is formed at the band tip portion 17c.

  For example, when the user carries the crime prevention device 1 in a pocket in a pocket, the wristband 3 can be removed and the housing 2 can be carried in a compact state.

  However, when the child's body is always provided for the intended purpose, the wristband 3 can be attached to the child's wrist.

  That is, as shown in FIG. 1, the wristband 3 is inserted into the pair of band insertion holes 11 and 11, and the band base portion 17 a is installed between the gate frames 12 and 12. At this time, the band insertion holes 11 and 11 are regulated by the both end edges of the base portion 13 facing the gate frames 12 and 12 so that the vertical dimension of the hole is substantially the same as the thickness of the band 3. Since the band base portion 17a is in frictional contact with both end edges of the base portion 13, the band base portion 17a and the casing 2 do not play with each other. Thereafter, the band tip end portion 17b and the band tip end portion 17c are wound around the outer periphery of the user's wrist while facing each other so as to draw a loop, and the band tip end portion 17c is inserted into the ring body 18 from the inside to the outside. . In this state, since the hook-and-loop fasteners 19a and 19b are located outward of the loop, if the band tip portion 17c is folded back by the foldable portion 21, the pair of hook-and-loop fasteners 19a and 19b face each other and are engaged with each other. To do.

  As shown in the figure, the hook-and-loop fastener 19b extends long along the band tip portion 17c. Therefore, when the wrist of the user is small, the band tip portion 17c is moved to the ring 18 until the loop of the wristband 3 extends along the wrist. The band front end portion 17c is folded back at the portion of the hook-and-loop fastener 19b, and the hook-and-loop fasteners 19b facing each other in the folded state may be engaged with each other.

  In a state where the wristband 3 is fastened to the wrist of the user without looseness, the pair of gate frames 12 and 12 come into contact with the surface of the wrist, but at the same time, the arc-shaped recess 16 of the rib 15 arranged therebetween is formed on the surface of the wrist. Since they are in contact with each other, the gate frames 12 and 12 do not bite into the surface of the wrist, and the wearing feeling is excellent.

  By the way, the operation piece 7 provided with the operation assisting piece 20 in a state in which the crime prevention device 1 is mounted on the wrist is in a state capable of moving forward and backward in the X-axis direction. That is, the X axis on which the operating piece 7 is to be operated is arranged in a direction intersecting the arm including the wrist. Accordingly, when operating the security device 1, it is only necessary to pick the operating piece 7 with the fingertip of the hand not wearing the security device and pull it in the X-axis direction intersecting the arm, which may cause an operation error. There is no such thing and the safety is high.
