Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a buckle used for connecting a shoulder belt to a storage case, etc.

[Prior Art] This type of buckle is provided with first and second buckle bodies that can be engaged with and disengaged from each other. For example, when used to connect a shoulder belt to a storage case,
One of the first and second buckle bodies is attached to the storage case and the other to the belt, and the belt can be connected to the storage case by engaging the first and second buckle bodies. Further, by separating the first and second buckle bodies, the belt can be removed from the storage case, and the belt can be attached to and removed from the storage case.

However, in conventional buckles of this type, a release operation member for releasing the first and second buckle bodies protrudes from either one of the first and second buckle bodies, and the storage case is There is a risk that the release operation member may be operated erroneously when carrying the bag, and there is a risk that the first and second buckle bodies may be released inadvertently.

[Problems to be solved by the invention] Taking the above-mentioned facts into account, the present invention aims to provide a buckle that prevents the first and second buckle bodies from unintentionally disassociating, and which is easy to disassemble. do.

[Means for Solving the Problems] In the buckle according to the present invention, a pair of engagement pieces that are formed in the insertion portion of the first buckle body and are elastically deformable in a direction approaching each other are attached to the second buckle body. In a buckle that is engaged with a claw provided in an insertion hole and in which a first buckle main body and a second buckle main body are engaged or disengaged, the engagement pieces are moved toward each other from the tip of the insertion portion toward the base. The second
A release operation member disposed inside the buckle main body so as to be slidable in the direction of movement of the insertion portion has an opening width wider than the width of the distal end of the insertion portion of the engagement piece, and a taper of the engagement piece. It is characterized by providing a recessed portion having an inclined surface that comes into contact with the surface.

[Function] In the buckle having the above configuration, since the release operation member for separating the first buckle body from the second buckle body is provided inside the second buckle body, the release operation member is not operated erroneously. This prevents the first and second buckle bodies from unintentionally disassociating. In addition, by sliding the release operation member toward the first buckle body, the tapered surface of the engagement piece that faces the inclined surface of the recess is pressed, and while increasing the pressing area, the engagement pieces are brought closer to each other. Since the locking state between the engagement piece and the pawl is released by elastically deforming them in the direction of engagement, the operating force can be small.

[Example] Figs. 1 to 5 show a buckle 10 to which the present invention is applied. In this embodiment, a buckle 10 is used to connect a shoulder belt 14 to a storage case 12, as shown in FIGS. 1, 2, and 5.

As shown in FIGS. 1 and 2, the buckle 10 includes a first buckle body 16, a second buckle body 18, and a release operation member 20.

The first buckle body 16 is integrally molded from synthetic resin, and has a mounting portion 21 and an insertion portion 22, as shown in FIGS. 3 and 4. The mounting portion 21 has a substantially rectangular planar shape, and a rectangular belt insertion hole 24 is formed substantially in the center. The insertion part 22 has a substantially rectangular planar shape whose longitudinal direction is in the width direction (direction perpendicular to the longitudinal direction) of the attachment part 21, and thin-walled engagement parts are formed on both sides in the width direction (direction perpendicular to the longitudinal direction). The insertion portion 22 is moved so that the pieces 26 are gradually separated from the insertion portion distal end side toward the insertion portion base side.
It is formed along the longitudinal direction of the insertion length with a space between. These engaging pieces 26 are connected to the insertion portion 22
It extends from the distal end of the insertion section 22 to near the base of the insertion section 22, and has a tapered surface 27 formed on its outer surface. Furthermore, the proximal end portions of the insertion portions 22 are free ends and are elastically deformable in the direction toward each other. A step portion 28 is formed at the free end side tip portion of each of these engaging pieces 26, and the tip side of the step portion 28 is made thinner. The stepped portion 28 has a gentle upward slope toward the distal end side of the engagement piece 26.

This first buckle body 16 is shown in FIGS.
As shown in the figure, the belt 14 is inserted into the belt insertion hole 24.
is inserted and locked, and the insertion portion 22 is inserted into the engagement piece 2 from the tip.
6 is inserted into the second buckle body 18.

The second buckle body 18 is integrally molded from synthetic resin, and has a substantially rectangular planar shape as shown in FIGS. 3 and 4. The second buckle main body 18 has a substantially cylindrical shape with an axis in the insertion/extraction direction of the first buckle main body 16 (in the direction of arrows A and B in FIGS. 3 and 4), and has a first The insertion portion 22 of the buckle body 16 is inserted together with the engagement piece 26. A pair of claws 36 (shown in FIG. 3) are formed protruding from the inner wall of the opening 34 at portions corresponding to the engaging pieces 26 of the first buckle body 16 and facing each other. The distance between these claws 36 is the maximum distance between the engagement pieces 26 in the free state (the distance between them near the stepped portion 28).
The first buckle body 1 is smaller than the first buckle body 1.
The insertion portion 22 of No. 6 is inserted into the opening 34 while elastically deforming the engaging pieces 26 in a direction toward each other, and when the stepped portion 28 of the engaging piece 26 is inserted deeper than the claw 36, the engaging piece 26 is restored to its shape and the stepped portion 28 becomes the claw 36.
It is designed to be locked and prevented from being pulled out.

This second buckle body 18 has a substantially rectangular hole 38 (shown in FIG. 3) formed at the center of the back surface, and a substantially trapezoidal notch 40 (shown in FIG. 4) on the opposite surface. ) and counterbored hole 30 (fourth
(shown in the figure) is formed. Inside the hole 38, a substantially trapezoidal protrusion 42 (shown in FIG. 3) protrudes toward the insertion direction of the first buckle body 16 (direction of arrow A in FIG. 3). A groove 44 is formed on the surface of the protruding piece 42 on the side of the opening 34 along the insertion/extraction direction of the first buckle body 16 (directions of arrows A and B in FIGS. 3 and 4). The notch 40 is inserted in the direction of insertion of the first buckle body 16 (direction of arrow A in FIG. 4).
It is formed at the side end. The counterbore hole 30 is the opening 3
They are formed on both sides of 4.

As shown in FIG. 1, this second buckle body 18 is fixed to the storage case 12 by tightening a screw 32 (also shown in FIG. 4) through a counterbore hole 30. The insertion portion 22 is inserted to a position where withdrawal is prevented, that is, a position where the stepped portion 28 is locked by the claw 36 and engaged with the first buckle body 16, thereby storing the belt 14. It is connected to case 12.

The release operating member 20 is integrally molded from synthetic resin and is mounted within the opening 34 of the second buckle body 18, as shown in FIGS. 3 and 4. This release operation member 20 is formed with a guide block 46 that engages with the groove 44 in a portion corresponding to the groove 44 of the second buckle main body 18, and the release operation member 20 is guided by the groove 44 and moved to the first buckle main body. 1
It is movable in the insertion/extraction direction of 6 (directions of arrows A and B in FIGS. 3 and 4).

A recess 48 is formed at a portion of the dissociation operation member 20 that is accommodated in the hole 38 . This recess 48
The width of the opening is wider than the width of the tip of the engagement piece 26 on the insertion side, and the width of the bottom surface is narrower. As a result, an inclined surface 49 corresponding to the tapered surface 27 of the engagement piece 26 is formed, and by sliding the dissociation operation member 20 in the direction of the first buckle body 16, the inclined surface 49 is formed on the engagement piece 26. Tapered surface 27 of
and press the tapered surface 27 from both sides,
While increasing the pressing area, the engaging pieces 26 are elastically deformed in a direction in which they approach each other.
The locking state between the stepped portion 28 and the claw 36 is released. Furthermore, a notch 51 is formed approximately in the middle of the dissociation operation member 20, as shown in FIG. This notch 51 is locked to the tip of the protruding piece 42, and is inserted in the insertion direction of the first buckle body 16 (the third
The movement of the release operation member 20 in the direction of arrow A in FIGS. The block 50 comes into contact with the inner periphery of the notch 40 to restrict the movement of the release operation member 20 in the direction of extraction of the first buckle body 16 (in the direction of arrow B in FIGS. 3 and 4). This block 50 allows the release operation member 20 to move in the direction of extraction of the first buckle body 16 to a position immediately before contacting the claw 36.

This release operation member 20 is connected to the second buckle main body 1.
When the first buckle main body 16 is inserted into the second buckle main body 18, the first buckle main body 16 corresponds to the tip of the insertion part 22 of the first buckle main body 16, and when the first buckle main body 16 is engaged with the second buckle main body 18, As shown in FIGS. 1 and 2, the first buckle body 16 is moved in the insertion direction.
The dissociation operation member 20 in this state is shown in FIGS.
As shown in the figure, it is exposed to the outside of the second buckle body 18 through the notch 40, and the tip of the insertion portion 22 of the first buckle body 16 is pressed by manual operation to remove the first buckle body 16. The first buckle main body 16 is pressed by this release operation member 20 and moves into the second buckle main body 1.
It is designed to be extruded and released from 8. To explain in detail, when the dissociation operation member 20 is moved in the direction of removing the first buckle body 16, the inclined surface 49 comes into contact with the tapered surface 27 of the engagement piece 26, and presses the tapered surface 27 from both sides. Then, while increasing the pressing area, the engaging pieces 26 are elastically deformed in a direction toward each other, and the locked state between the step portion 28 of the engaging piece 26 and the pawl 36 is released. By this,
The first buckle body 16 is the second buckle body 1
It is extruded and released from 8.

According to the above configuration, the release operation member 20 for separating the first buckle main body 16 from the second buckle main body 18 is provided inside the second buckle main body 18 so that the first buckle main body 16 and the second buckle main body 18 can be separated from each other. Since the release operation member 20 is prevented from protruding from the second buckle body 18 when engaged with the second buckle body 18, the release operation member 20 is not operated erroneously when carrying the storage case 12, and the second buckle body 18 is engaged with the second buckle body 18. The first buckle body 16 will not be unintentionally separated from the second buckle body 18.

In this embodiment, since each part constituting the buckle 10 is made of synthetic resin, rust does not occur and the latch noise is small. Further, it can be changed to various colors, and in particular, if the color is set to match the color of the storage case 12, the sense of unity with the storage case 12 will be increased and the appearance will be improved.

[Effects of the invention] Since the present invention has the above structure, it is possible to obtain a buckle in which the first buckle main body and the second buckle main body are not unintentionally separated, and the releasing operation is easy.
