Description

buckle

This invention relates to a buckle that connects each band-like body by fastening a male member to which one band-like body is attached to a female member to which the other band-like body is attached.

装 Accessories such as bags and backpacks, clothing, etc. are provided with buckles for connecting a plurality of strips. For example, the backpack is provided with a chest strap or the like that is stretched across the chest for the purpose of fitting the backpack to the user's body.

As an example of this chest strap, Patent Document 1 describes a configuration as shown in FIG. The chest stop includes belt-like bodies B1 and B2 attached to one shoulder belt S, a cross-type female buckle 101 attached by crossing the belt-like bodies B1 and B2, and a belt-like body attached to the other shoulder belt S. It consists of a body B3 and a male buckle 102 attached to the strip-shaped body B3. The female buckle 101 and the male buckle 102 are made of resin, and are inserted into and engaged with the insertion opening 104a provided in the main body 104 of the female buckle 101 while bending the insertion leg portion 103 of the male buckle 102. 102 and the male buckle 102 are connected. The female buckle 101 includes a through portion 105 through which the vertically extending strip B1 passes and a through portion 106 through which the horizontally extending strip B2 passes. In addition, as a structure of this female buckle, there exists a straight type which can attach only one strip | belt-shaped body other than a cross type.

In this buckle, since the female buckle 101 is configured to receive the entire insertion leg portion 103 of the male buckle 102, the thickness of the main body 104 of the female buckle 101 needs to be greater than the thickness of the insertion leg portion 103. It was. Further, in the cross type female buckle 101, since the through portion 106 is provided below the main body 104, the entire female buckle is enlarged in the thickness direction. For this reason, the female member of the buckle is required to be downsized for the purpose of reducing the weight and improving the aesthetic appearance.

In contrast, in Patent Document 2, as shown in FIG. 13, a buckle including a male member 110 having a first piece 115 and a second piece 117 and a female member 112 for receiving the first piece 115. Is described. The male member 110 and the female member 112 are provided with

attachment portions

113 and 114 for attaching the strips B4 and B5 at their ends. The first piece 115 of the male member 110 to which the belt-like body B4 is attached is inserted into the insertion portion 116 of the female member 112. The second piece 117 of the male member 110 slides on the surface of the female member 112 in a bent state. Then, by bending back at the receiving end position, the engaging portion 118 formed on the second piece portion 117 and the engaged portion (not shown) of the female member 112 are engaged, and the second piece portion 117 becomes female. It is fixed to the surface of the member 112. For this reason, compared with the buckle of the conventional structure which inserts the whole insertion part of a male member in a female member, size reduction in the height direction of the female member 112 can be achieved by the thickness of the 2nd piece part 117. FIG.

An inclined surface 32 a is formed at the tip of the protrusion 32 on the opening 21 side of the first slot portion 20.

Next, the male member 15 will be described. As shown in FIG. 5, the male member 15 includes an adjustment tape attachment portion 40, and the adjustment tape attachment portion 40 has a first insertion hole 41 and a second insertion hole 42. The first insertion hole 41 and the second insertion hole 42 are formed to penetrate from the upper surface of the male member 15 toward the lower surface. In addition, an inclined surface 41 a that is inclined toward the lower surface of the male member 15 is formed on the right end surface 15 a side of the first insertion hole 41.

The adjusting tape 14 passes from the lower opening of the first insertion hole 41 through the upper opening and passes from the upper opening of the second insertion hole 42 toward the lower opening. The adjustment tape 14 drawn out from the second insertion hole 42 is extended in parallel with the adjustment tape 14 drawn out from the first insertion hole 41 on the bottom surface side of the male member 15.

Further, the male member 15 includes a first piece 51 and a second piece 52 that are formed to extend from the adjustment tape attachment portion 40. As shown in FIG. 6, the first piece 51 and the second piece 52 are provided in parallel via a space 53.

The male member 15 is fixed to the female member 11 in a state where a part of the cutout portion 27 and the upper wall portion 26 of the female member 11 is sandwiched between the spaces 53. That is, the first slot portion 20 of the female member 11 is formed at a height that can receive the second piece portion 52 of the male member while the horizontal tape 12 is inserted. The first piece 51 is inserted into the first slot portion 20 of the female member 11, and the second piece 52 is fixed to the surface of the upper wall portion 26 of the female member 11.

The first piece 51 is formed in a substantially flat plate shape, and has an inclined surface 51 a that is inclined toward the lower surface of the male member 15 at the tip thereof. That is, the inclined surface 51 a is inclined toward the insertion direction into the female member 11. Moreover, as shown in FIG. 7, the 1st piece part 51 has the through-hole 51b in the center. The length L1 of the first piece 51 is the length L2 from the opening 21 of the female member 11 shown in FIG. 4A to the tip of the locking projection 31 provided in the first slot portion 20. It is almost the same. Moreover, the width W1 of the 1st piece part 51 shown in FIG. 7 is substantially the same as the width W2 between each protrusion 32 shown to Fig.4 (a).

As shown in FIG. 7, the engaging portion 57 is formed perpendicular to the back surface of the second piece portion 52 and extends in the width direction of the second piece portion 52. A rib 58 is formed from the side surface of the engaging portion 57 on the operation portion 56 side.

(Function)
Next, the operation of the buckle will be described. First, as shown in FIG. 8A, the horizontal tape 12 is inserted into the first slot portion 20 through the

openings

21 and 22 of the female member 11. Since the corner | angular R part 23 is formed in the opening 21 side of the female member 11 at this time, the horizontal tape 12 is easy to insert. Further, the vertical tape 13 is passed through the second slot portion 25 of the vertical tape mounting portion 24. Further, the adjustment tape 14 is inserted into the adjustment tape mounting portion 40 of the male member 15.

Further, the opening 21 of the female member 11 through which the horizontal tape 12 and the vertical tape 13 are inserted is opposed to the tip of the first piece 51 of the male member 15 through which the adjustment tape 14 is inserted. The first piece 51 of the male member 15 is inserted into the first slot portion 20 of the female member 11 and above the horizontal tape 12. At this time, as described above, the end surface 11r of the female member 11 is a curved surface that is recessed with the notch 27 as a center. For this reason, when the male member 15 is inserted into the female member 11, even if the tip of the male member 15 deviates from the notch 27 and is pressed against the end surface 11r, the male member 15 is slid along the lateral direction of the end surface 11r. Thus, it can be guided in the direction of the notch 27.

Further, since the inclined surface 29 is provided on the opening side of the female member 11 and the inclined surface 51 a is provided on the first piece 51 of the male member 15, the male member 15 includes the first piece 51. It is inserted into the female member 11 while gradually contacting the inclined surface 29 of the female member 11. That is, the male member 15 is inserted obliquely with respect to the vertical direction with respect to the insertion direction of the male member 15 into the first slot portion 20 (the direction from one opening 21 of the slot portion 20 toward the other opening 22). Even in such a case, the male member 15 can be inserted smoothly.

And the 1st piece part 51 is guide | induced between the protrusions 32 from the inclined surface 32a of the protrusion 32 formed in the 1st slot part 20, and is clamped by the protrusion 32, The 1st slot part 20 is positioned. Further, the height of the opening 21 and the first slot portion 20 of the female member 11 is formed slightly longer than the sum of the thickness of the lateral tape 12 and the thickness of the first piece portion 51. For this reason, the 1st piece part 51 is inserted, without moving the horizontal tape 12 penetrated in the 1st slot part 20 unnecessarily. Moreover, since the inclined surface 32a is formed in the protrusion 32 and the corner | angular R part 23 and the inclined surface 29 are formed in the opening 21 side of the female member 11, the 1st piece part 51 is easy to insert.

On the other hand, the second piece 52 of the male member 15 is inserted into the notch 27 of the female member 11. At this time, the engaging portion 57 of the second piece 52 abuts on the inclined surface 28 provided at the end of the notch 27. When the male member 15 is further pushed into the female member 11, the engaging portion 57 that has been in contact with the inclined surface 28 slides the inclined surface 28 toward the engaged portion 30, as shown in FIG. Move. Along with this, the second piece 52 of the male member 15 bends so as to warp from the inclined surface 28. At this time, the first piece 51 slides on the back surface of the upper wall portion 26 of the female member 11 while being guided by the protrusion 32.

When the male member 15 is further pressed from the state shown in FIG. 8B, the engaging portion 57 of the male member 15 reaches the top of the inclined surface 28. When the engaging portion 57 reaches the position of the engaged portion 30 of the female member 11, the engaging portion 57 is engaged by the restoring force of the second piece portion 52 as shown in FIG. The male member 15 is inserted into the joint portion 30 and fastened to the female member 11. Even if it is attempted to pull out the male member 15 from the female member 11 without bending the second piece 52 by the engagement of the engaging portion 57 and the engaged portion 30, the engaging portion 57 and the engaged portion 30 It cannot be pulled out by engagement.

When releasing the fastening of the female member 11 and the male member 15, a force in a direction of separating from the female member 11 is applied to the operation portion 56 of the male member 15. For example, the back surface of the operation unit 56 is pressed with a finger, and the operation unit 56 is pressed away from the female member 11. By applying such a force, the second piece 52 of the male member 15 is bent so as to be warped, and the engaging portion 57 of the male member 15 is extracted from the engaged portion 30 of the female member 11. The fastening is released by sliding the male member 15 away from the female member 11 while maintaining this state.

In this way, the female member 11 is inserted through the horizontal tape 12 in a state where the horizontal tape 12 is flattened without being bent in the middle of the first slot portion 20, so that the mounting portion for attaching the horizontal tape 12 is a female member. There is no need to provide it below 11 or the like. Moreover, even if the space which allows the horizontal tape 12 to pass through is secured in the first slot portion 20 into which the first piece 51 of the male member 15 is inserted, the horizontal tape 12 has a thickness of about 1 mm or less. Since it is thin, the female member 11 is not enlarged in the height direction by providing the space. Therefore, the female member 11 can be downsized not only in the height direction but also in the width direction by an amount corresponding to the attachment portion of the lateral tape 12. For this reason, since the protrusion amount of the female member 11 from the surface of the shoulder belt S of a backpack becomes small, while making it difficult for a user's hand to be caught, aesthetics can be improved. Further, as described above, the vertical tape 13 is provided with a buckle such as a so-called D-ring, and climbing equipment may be attached to the buckle, so that the climbing equipment is less likely to be caught on the female member 11.

According to the first embodiment, the following effects can be obtained.
(1) In the first embodiment, the female member 11 is configured such that a part of the upper wall portion 26 is received between the first piece 51 and the second piece 52 of the male member 15 so that the male member 15 Therefore, the female member 11 can be made thinner than a buckle having a conventional configuration in which the entire insertion portion of the male member 15 is accommodated in the female member. Moreover, since the female member 11 can insert the horizontal tape 12 and the first piece 51 of the male member 15 into the first slot portion 20, the mounting portion for attaching the horizontal tape 12 to the female member 11 is a female member. 11 is not required to be provided so as to protrude from 11. For this reason, the female member 11 can be reduced in size in the width direction parallel to the longitudinal direction of the horizontal tape 12.

(2) In the first embodiment, since the female member 11 is fixed in a state where the horizontal tape 12 and the vertical tape 13 are crossed, the position of the female member 11 is difficult to shift on the shoulder belt S of the backpack. 15 is easily fastened or released to the female member 11. In addition, the cross-type female member of the conventional configuration is easy to increase in size because a plurality of attachment portions for attaching one band-like body are provided on the side surface and the bottom surface, but in the first embodiment, the first of the female member 11 is the first. Since the horizontal tape 12 is inserted into the slot portion 20, the effect can be exhibited particularly in terms of thinning.

(3) In the first embodiment, the first slot portion 20 includes the

openings

21 and 22 through which the horizontal tape 12 is inserted in parallel, so that the horizontal tape 12 is inserted without being bent in the first slot portion 20. it can. For this reason, the space occupied by the horizontal tape 12 in the first slot portion 20 can be minimized. Moreover, since the horizontal tape 12 is not pulled out from the surface of the female member 11, but pulled out from the right end surface 11b and the left end surface 11c, the height of the buckle including the tape can be lowered.

(4) In the first embodiment, the corner R on the opening side of the first slot portion 20 is provided with the corner R portion 23, so that the lateral tape 12 can be easily received. Moreover, even if the horizontal tape 12 is inserted through the first slot portion 20, the first piece portion 51 of the male member 15 can be easily received.

(5) In 1st Embodiment, since the protrusion 32 which can clamp the 1st piece part 51 of the male member 15 is provided in the side surface of the 1st slot part 20, the 1st piece part 51 is made into 1st. It can be inserted while positioning in the slot portion 20. For this reason, the space for inserting the first piece 51 can be minimized. Further, when the first piece 51 is inserted into the first slot portion 20, the horizontal tape 12 inserted through the first slot portion 20 is not displaced or twisted.
