[Problems to be solved by the device]

In consideration of the above facts, the present invention has an object to obtain a bag which can surely prevent accidental dissociation of both bag main bodies.

[Means for solving the problem]

The buckle of the present invention has a first buckle body and a second buckle body into which the first buckle body is inserted, and the engaging piece and the pressing piece are provided on the first buckle body so as to project therefrom. When the first buckle body is inserted into the second buckle body, it is inserted into the second buckle by narrowing the included angle between the pressing piece and the engaging piece, and the shape is restored at a predetermined insertion position to restore the second buckle body. A buckle to engage with,
The second buckle body has a biasing means which is formed on the second buckle body and is pushed by the engaging piece of the first buckle body by the insertion of the first buckle body to press the engaging piece in the engaging direction by a flexible elastic reaction force. The biasing means is exposed to the outside of the insertion portion of the second buckle body into which the first buckle body is inserted.

[Action]

In the present invention having the above-described structure, the first buckle body is inserted into the second buckle body by reducing the included angle between the pressing piece and the engaging piece, and the shape is restored at a predetermined insertion position in the second buckle body. Engage the piece with the second buckle body.

The urging means formed on the second buckle body directly presses the engagement piece of the first buckle body, and this pressing force causes the engagement state between the first buckle body and the second buckle body to be changed. It acts as a power to maintain. That is, the force for maintaining the engaged state directly acts from the second buckle body to the first buckle body.

As a result, compared to the conventional buckle, the engagement state can be maintained with a larger force. Further, even if an unnecessary force acts on the first buckle body, the engagement state between the first buckle body and the second buckle body is not released.

Furthermore, since the biasing means is exposed to the outside of the insertion portion of the second buckle body, the degree of freedom in selecting the shape and position is widened, and the force for maintaining the engaged state can be easily changed.

Twenty is shown.

In this embodiment, the bag 20 is used for connecting a shoulder belt 24 to a storage case 22 as shown in FIG. As shown in FIG. 1, the bag 20 is provided with a first bag body 26 and a second bag body 28, and a belt 24 is wound around the first bag body 26 as shown in FIG. When stopped, the second bag body 28 is attached to the storage case 22 with screws 30 and the belt 24 is attached to the storage case 22 by the engagement of the first and second bag bodies 26 and 28 as shown in FIG. Can be connected.

The first bag body 26 has a base 32 as shown in FIG.
A belt winding member 33 is rotatably supported on the belt, and a belt 24 is wound around and locked on the belt winding member 33 as shown in FIG. The first bag body 26 has an engaging piece 34 extending from the base portion 32, and is inserted into the second bag body 28 from the tip of the engaging piece 34.

The engaging piece 34 has a plate shape with a widened tip, and a wide portion 38 is formed at the tip.
Are formed. On one surface of the wide portion 38, a raised portion 40 is formed at a substantially central portion in the width direction so that the wide portion 38 is partially thick. The raised portion 40 is gradually raised from the tip of the wide portion 38 toward the base portion 32 side, and a step portion 42 is formed on an extension of the end surface 38A of the wide portion 38 on the base portion 32 side.

The engagement piece 34 is relatively thin and can be elastically bent and deformed in the thickness direction, that is, in the direction of arrow D in FIGS. 1 and 2. On both sides of the engaging piece 34 in the width direction, pressing pieces 36 are spaced apart from each other along the engaging piece 34 from the base 32 and are inserted into the second bag main body 28 together with the engaging piece 34. ing.

The longitudinal axis of the pressing piece 36 is the engaging piece as shown in FIG.
It is inclined at an angle θ with respect to 34, so that the insertion portion into the second bag body 28 is partially thickened (dimension E). Therefore, when the engaging piece 34 is inserted into the second bag body 28, the thickness E can be reduced by bending the engaging piece 34 in the direction of arrow D in FIGS.
The included angle between and is reduced.

As shown in FIG. 1, the second bag main body 28 has a box shape, and a counterbore hole 46 is formed in its bottom plate 44.
Through 46, store case 22 with screws 30 as shown in FIG.
Attached to. An engagement block 50 is formed on the bottom plate 44 of the second bag body 28.

The engagement block 50 has a substantially U-shape, and by fixing both legs to the bottom plate 44, an insertion hole 56 for inserting the first bag body 26 is formed between the engagement block 50 and the bottom plate 44. As shown in FIG. 4, the engagement block 50 has a pair of blocks 58 formed at a portion facing the bottom plate 44 at predetermined intervals.

The block 58 is an engaging piece when the first bag body 26 is inserted.
It faces the wide part 38 of 34. As shown in FIG. 2, the block 58 extends in the inserting direction of the first bag body 26 from the inlet side at the upper end of FIG. The width of 56 is gradually reduced from the inlet side to the outlet side, and when the first bag body 26 is inserted, the wide portion is formed near the outlet of the insertion hole 56.
38 can be pressed in the direction of reduction of the thickness dimension E (shown in FIG. 2).

More specifically, the block 58 has an opening height dimension H (shown in FIG. 2) on the outlet side of the insertion hole 56 in which the engagement piece 34 is in a free state. The block 58 is made smaller than that shown in FIG. 2 so that when the first bag body 26 is inserted, the block 58 causes the wide portion 38 to have a thickness E.
Is pressed in the direction of contraction so as to pass through the insertion hole 56. After the wide portion 38 has passed through the insertion hole 56, the engaging piece 34
The end face 38A of the wide portion 38 is locked to the block 58 and the stepped portion 42 of the raised portion 40 is engaged with the engaging block 50 by restoring the shape of FIG.
The engaging piece 34 is locked to the main body portion of the vehicle to prevent the engaging piece 34 from slipping out of the insertion hole 56, whereby the first vehicle body 26 is engaged with the second vehicle body 28 as shown in FIG. It is like this.

As shown in FIG. 4, a groove 60 is formed between these blocks 58 along the insertion direction of the first bag main body 26 to partially reduce the thickness of the engagement block 50. Groove 60
Faces the ridge 40 when the first bag body 26 is inserted,
It serves as an escape for the raised portion 40 when the wide portion 38 passes through the insertion hole 56.

On the opposite side of the engagement block 50 from the insertion direction of the first bag body 26, a holding piece 52 as a biasing means is projected from the bottom plate 44.

The holding piece 52 rises diagonally from the bottom plate 44 along the inserting direction of the first bag body 26 and the first bag body 26.
When the first bag body 26 is inserted, the tip of the wide portion 38 of the engaging piece 34 is pressed to bend. Then, the first bag body shown in FIG.
With the engagement state of 26, the wide portion 38 is pressed in the direction of arrow N in FIG. 3,
The component force N1 pushes the wide portion 38 toward the side where the raised portion 40 is provided, and the component force N2 pushes the wide portion 38 in the direction of extraction from the insertion hole 56.

The holding piece 52 has a first force N1 that presses the wide portion 38 toward the side where the raised portion 40 is provided in the engaged state of the first bag body 26.
It is set to be larger than the bending force of the engagement piece 34 of the bag body 26. More specifically, as shown in FIGS. 5 and 6, the width dimension of the holding piece 52 is S, the thickness dimension of the holding piece 52 is T, the base of the holding piece 52 to the first bag body.
The length of the holding piece 52 up to the contact portion between the holding piece 52 and the engaging piece 34 in the engagement state of 26 is V, the width dimension of the bending portion of the engaging piece 34 is X,
The thickness of the bending portion of the engaging piece 34 is Y, and the first bag main body
When a tensile load in the direction of arrow F in FIG. 6 acts on the first bag body 26 in the engaged state of 26, the engagement piece 34 and the holding piece 52 are separated from the center of the moment M acting on the engagement piece 34. If the length of the engagement piece 34 up to the contact portion is Z, Has become. As a result, the force N1 by which the holding piece 52 presses the wide portion 38 toward the side where the raised portion 40 is provided in the engaged state of the engaging piece 34 of the first vehicle body 26 is the engagement of the first vehicle body 26. It is larger than the bending force of the piece 34.

By this setting, the holding piece 52 can prevent the engaging piece 34 of the first bag body 26 from being accidentally disengaged. That is, the force with which the holding piece 52 presses the wide portion 38 toward the side where the raised portion 40 is provided in the engaged state of the first bag body 26.
Since N1 is made larger than the bending force of the engagement piece 34 of the first bag body 26, a tensile load in the direction of arrow F in FIG. Even if the moment M around the base portion acts, the holding piece 52 is not pressed and bent by the wide portion 38, and the wide portion 38 is reliably held at the engaging position.

An opening / closing lid 54 is attached to the side plate 48 of the second bag main body 28 thus configured, as shown in FIG.

The opening / closing lid 54 is integrally formed with a pin 62 and is rotatably supported by the side plate 48 via the pin 62. The opening / closing lid 54 is rotated around the pin 62 so that the inside of the second bag main body 28 can be opened and closed. ing. A lock claw 64 and a protrusion 66 are formed on the opening / closing lid 54 on the side opposite to the pin 62. The locking claw 64 engages with the side plate 48 when the opening / closing lid 54 is closed so that the opening / closing lid 54 can be locked in the closed state. The projecting piece 66 projects outside the side plate 48 when the opening / closing lid 54 is closed, and acts as a knob when the opening / closing lid 54 is opened.

 Next, the operation of this embodiment will be described.

In the bag 20, the belt 24 is connected to the storage case 22 by the engagement of the first bag main body 26 and the second bag main body 28. The second bag body 28 is engaged with the first bag body 26 with the opening / closing lid 54 closed.

The engagement between the first and second bag bodies 26 and 28 is the first bag body 26 in the disengaged state shown in FIG.
Is the insertion hole of the second bag body 28 from the tip side of the engaging piece 34.
Inserted in 56. When the engaging piece 34 is inserted into the insertion hole 56, the wide portion 38 faces the block 58 of the second bag body 28 and is pressed against the block 58 near the outlet of the insertion hole 56. By this pressing, the wide portion 38 bends the engaging piece 34 in the contracting direction of the thickness dimension E (shown in FIG. 2) and passes through the insertion hole 56. In this case, the engagement piece 34 may not bend, and the pressing piece 36 may bend. By the subsequent restoration of the shape of the engaging piece 34, the end surface 38A of the wide portion 38 is locked to the end surface of the block 58, and the step portion 42 of the raised portion 40 is locked to the main body of the engaging block 50. The withdrawal of 34 is prevented, so that the first bag body 26 is replaced with the second bag body 26 as shown in FIG.
28 engaged.

Here, when the wide portion 38 of the engaging piece 34 passes through the insertion hole 56, it is pressed by the wide portion 38 to bend the holding piece 52, and when the first bag body 26 is engaged, the wide portion 38 holds the holding piece 52. The engaging piece 34 is pressed against the unintentional disengagement. That is, in the holding piece 52, the force N1 for pressing the wide portion 38 toward the side where the raised portion 40 is provided in the engaged state of the first bag body 26 is set to be larger than the bending force of the engaging piece 34. 6, even if a tensile load in the direction of arrow F in FIG. 6 acts on the first bag body 26 and the moment M about the base portion acts on the engaging piece 34, the holding piece 52
The wide portion 38 is not pressed by the wide portion 38 and is not bent, and the wide portion 38 is reliably held at the engagement position with the engagement block 50.

When the first bag main body 26 and the second bag main body 28 are disengaged to remove the belt 24 from the storage case 22,
From the engaged state shown in the figure, the opening / closing lid 54 is opened to press the wide portion 38 of the engaging piece 34 of the first bag body 26 against the elastic force of the holding piece 52 and the elastic force of the engaging piece 34. Then, the wide portion 38 bends the engaging piece 34 in the reduction direction of the thickness dimension E and can be pulled out from the insertion hole 56, and at the same time, the wide portion 38 is pressed by the holding piece 52 and pulled out from the insertion hole 56. It is played in the outgoing direction. That is, the wide portion 38 is a component of the force with which the holding piece 52 presses the wide portion 38.
It is ejected in the direction of extraction from the insertion hole 56 with N2. When the first bag body 26 is pulled out as required, the first bag body 26 and the second bag body 28 are disengaged as shown in FIG. 2 and the belt 24 is detached from the storage case 22. It should be noted that if the component force N2 of the force with which the holding piece 52 presses the wide portion 38 is set to a large value, the wide portion 38 is pressed by pressing the wide portion 38.
Can be removed from the insertion hole 56, and at the same time, the wide portion 38 can be ejected from the insertion hole 56, and thereafter the first bag body 26 and the second bag body 26 can be removed without pulling out the first bag body 26.
The bag body 28 can be easily dissociated.

In this embodiment, the opening / closing lid 54 is the first bag body.
Since the closed state is established by the engagement between the 26 and the second bag main body 28, the wide portion 38 of the first bag main body 26 is not pressed by a shock when the storage case 22 is carried, and the storage case 22 is stored. The first and second bag bodies 26 and 28 are not accidentally disengaged due to an impact when the case 22 is carried.
