9' are positioned relatively close to each other. Therefore, as shown in FIG. 2, when the bell (B) is passed alternately through both bars 8, 9, the middle of its length is bent into a Z-shape with its part touching both corners 8', 9', and the bell is bent into a Z-shape. When )B is pulled in the pulling direction, the middle of the length of bell)H comes into close contact with both corners 8' and 9', and bell)B is prevented from coming off. In addition, when adjusting the length of the belt (B) after attaching it, the length of the belt (B) can be freely adjusted by sliding the respective surfaces of both bars 8 and 9 and sequentially feeding the bell (B) in one direction. It can be adjusted to

The insertion piece 6 is provided with an elastic operation piece lO extending diagonally backward from its upper surface, and as seen, it forms a tongue piece shape with a portion surrounded by a roughly U-shaped notch raised, and its free end 10 ′

A pair of bent ends 11, 11 bent in a substantially downward U-shape are provided at both ends thereof, and a tapered surface 11' inclined obliquely downward is formed at the tip of each bent end 11.

Further, as shown in FIGS. 6 to 14, the female member 3 includes a vertically flat cylindrical portion 12 with one end open for receiving the insertion piece 6, and an upper wall 13 of the cylindrical portion 12. a rectangular window portion 14 into which the elastic operation piece 10 of the opened insertion piece 6 fits;
A hollow accommodating part l6 that is connected to the lower wall 15 of the cylindrical part 12 and has at least one surface opening outward, and this accommodating part 16
Opening surface! In addition to a lid part 17 for closing 6', the belt mounting part 4 has the same structure as the belt mounting part 4 of the male member 2, and each part except the lid part 17 is integrally molded of plastic.

As shown in FIGS. 9 and 10, the lower wall 15 of the cylindrical portion 12 is provided with a pair of slide grooves 18 and 18 in which the bent end portion 11 of the insertion piece 6 can slide. This restricts the insertion direction of 6 and prevents wobbling after insertion.

The accommodating portion 16 has a case shape with an open bottom surface, as shown in FIG. ar14 and FIG.
The lower wall 15 bent in a downward U-shape of 2 is used to form the upper surface and left and right side surfaces of the lower wall 15, and the space below the cylindrical part 12 is utilized to create an upper and lower two-tiered structure, thereby increasing the overall thickness of the female member 3. I try not to involve it.

Moreover, the lid part 17 is shown in FIGS. 12 to 14r! ! As shown in J, it is a flat plate, in this case separately molded from plastic, and has a plurality of elastic locking pieces 19 protruding from its top surface, and these elastic locking pieces 19 are inserted into the housing portion 16. By engaging with the formed engagement recess 20..., the lid part! 7 can be locked in the closed state. Note that the lid part 17 may be connected to the housing part 16 by a hinge, or
The housing portion 16 may be provided with an elastic locking piece, and the lid portion 17 may be provided with an engaging recess.

On the other hand, as shown in FIG. 1, the accommodating portion 16 accommodates, for example, an electronic music box 22 as an acoustic element using a contact switch 21 as a switching element. This electronic music box 22 is made into a unitary/ A diaphragm 24 using an element (not shown) and a contact switch 2
1, an electronic board section 23, and a diaphragm 24, and an annular spacer 25 that accommodates them together. Then, a melody sound is input to the IC, and when the contact switch 21 is pressed, the melody sound is continuously input to the diaphragm 2 for a certain period of time, for example, 30 seconds.
The melody starts from 4 onwards. Of course, the acoustic element is not limited to the electronic music box 22, but may be a simple electronic buzzer, and the electronic sound to be generated is not limited to a melody, but may also generate a sound.

An electronic music box 2 is provided on the lower wall 15 of the cylindrical portion 12.
An elastic protrusion 26 for pressing the second contact switch 21 is provided. This elastic protrusion 26 is connected to the lower wall 15 of the cylindrical portion 12.
A hemispherical projection 27 is provided on the lower surface of the free end so that the projection 27 faces the contact switch 21.

Next, as shown in FIGS. 1 and 15, the electronic music box 22 is placed through the opening surface 16' of the housing section 16, and the lid section 17 is fitted to the opening surface 1G'. , Lid! Spacer 2 of electronic music box 22 on the top surface of 7
The spacer 25 of the electronic music box 22 is raised on this pedestal 28, so that the spacer 25 of the electronic music box 22 is raised.
is inserted into and held in the housing part 1 together with the lid part 17.
It is fitted into the opening surface 16' of No. 6.

When the lid part 17 is fitted in this way, the elastic locking piece 19 engages with the engagement recess 20 of the housing part 16 and is bent, and as shown in FIG. 16, when it is restored by its elastic force. The opening surface 16' of the accommodating part 16 snaps into the engaging recess 20.
is closed by the lid part 17, and the contact switch 21 of the electronic music box 22 faces the protrusion 27 of the elastic protrusion part 26. At this time, the protrusion 27 is pushed from below by the large hemispherical surface of the upper surface of the contact switch 21. Raised, elastic protrusion fi
The free end of 26 projects into the cylindrical portion 12 . Incidentally, when the electronic music box 22 breaks down or the battery is replaced, the lid 17 can be opened and closed by bending the elastic locking piece 19 with the tip of a screwdriver (not shown) or the like.

Next, the procedure for attaching and detaching both members 2 and 3 will be explained. First, as shown in FIG.
It is only necessary to insert it in line with the opening 12' of the cylindrical part 12.

That is, when the insertion piece 6 of the male member 2 is inserted, the elastic operation piece 10 is inserted into the opening 12 of the cylindrical part 12, as shown in FIG.
', bends downward and advances into the cylindrical part 12. When the elastic operation piece 10 reaches the window part 14, it is restored by its elastic force, and its free end 10' snaps onto the rear end of the window part 14, and the insertion piece 6 passes through the cylindrical part 12. Removal is prohibited, and the male member 2 and female member 3 are connected to each other.

Further, when the elastic operating piece 10 is inserted, its lower surface engages with the elastic protrusion 26 and pushes the elastic protrusion 26 downward. Therefore, the contact switch 21 is pressed and turned ON by the protrusion 27 of the elastic protrusion 26, the electronic music box 22 is operated, and a melody is played from its diaphragm 24. This melody sound indicates that the buckle 1 has been connected. The operator can be notified. In addition, when the buckle 1 is in the connected state, the elastic protrusion 26 is continuously pressed down by the elastic operation piece 10, and the contact switch 21 is continuously pressed down.
Although it is in the N state, the melody sound automatically stops sounding after it continues for about 30 seconds.

On the other hand, in order to release the above-mentioned connected state, the elastic operating piece 10 may be slightly pushed in with a finger through the window 14. In other words, when the elastic operating piece 10 is pushed in, the elastic operating piece 10 is bent downward, and the elastic operating piece 10 is bent downward. The free end 10' is engaged and disengaged from the rear end of the window part 14, and is pushed back a little toward the opening 12' of the cylindrical part 12 while restoring its elastic force, so that the insertion piece 6 of the male member 2 is inserted into the female member 3. Both members 2 and 3 can be easily separated by pulling them out from the cylindrical portion 12 of the member.

Furthermore, when the elastic operating piece 10 is pushed in, its lower surface descends slightly below the lower wall 15 of the cylindrical part 12 and the elastic protrusion 2
6 and presses down this elastic protrusion 26. Therefore, the contact switch 21 is pressed and turned ON by the projection 27 of the elastic projection 9912G, and the electronic music box 2
2 is activated, a melody is played from the diaphragm 24, and this melody can notify the operator that the buckle 1 has been released.

When the elastic operating piece 10 is completely pulled out, the contact switch 21 is turned off, but a timer (not shown) is activated, so the melody sound continues for about 30 seconds.

On the other hand, in the embodiment described above, the electronic music box 22 is built into the female member 2, but it may of course be built into the male member 3. However, the contact switch 21 may be operated directly against the sliding surface between the inner wall of the cylindrical portion 12 and the insertion piece 6.Furthermore, the timing at which the electronic music box 22 sounds can be adjusted depending on the buckle. It may be possible to make the electronic music box 22 sound during the loading/unloading process, or to make the electronic music box 22 sound when the contact switch 21 is operated. For example, the contact switch 21 may be connected to 0.

The electronic music box 22 may sound when the buckle 1 is released, and may stop sounding when the buckles 1 are connected to each other.

Furthermore, the switch element is not limited to the mechanical contact switch 21, but may also be a non-contact optical sensor switch 29 or a touch sensor switch.For example, if the optical sensor switch 29 is used, the As shown in FIG. 17, a circular through hole 30 may be opened in the lower wall 15 of the cylindrical portion 12 of the female member 3, and the light receiving surface of the optical sensor switch 29 may be exposed to this through hole 30. .

That is, when both members 2.3 are connected, the through hole 30 is poorly shaded by the insertion piece 6 of the male member 2, the optical sensor switch 29 remains OFF, and the electronic music box 22 does not operate. In contrast, the cylindrical portion 1 of the female member 3
When the insertion piece 6 of the male member 2 is removed from the opening 2, light reaches the optical sensor switch 29 through the window 14 and the through hole 30, so the optical sensor switch 29 is turned on and the electronic music box 22 is activated. . Also, insert the insertion piece 6 of the male member 2 into the female member 3.
Since the optical sensor switch 29 changes from ON to OFF when the electronic music box 22 is inserted into the cylindrical part 12, the electronic music box 22 may be operated using this switching operation. The same reference numerals are used for the same components as in the previously described embodiment, and detailed explanation thereof will be omitted.

Furthermore, although the male member 2 and the female member 3 are each provided with a belt attachment portion 4, the present invention is not limited to the belt B, and one may be directly fixed to a stroller, a bag, or the like.

(Effects of the Invention) As explained above, according to the present invention, an electronic sound such as a melody is generated from the built-in acoustic element in connection with the attachment and detachment of the buckle 1. Not only can this be confirmed by electronic sounds, but if the electronic music box 22 is built in as an acoustic element, it is possible to create a product that takes advantage of the characteristics of the electronic music box 22. By using the buckle 1 for seat belts and children's glue sacks, it is possible to provide a buckle 1 that allows infants and children to listen to melody sounds and that children can enjoy operating.

Furthermore, by increasing the volume of the electronic sound that is generated, it can be used even by people with weak hearing, and in addition, the electronic sound can be used to prompt or warn when the buckle 1 is attached or removed. It is possible to provide a buckle 1 with an extremely wide range of applications and high added value.
