Description

新規性喪失の例外適用申請有り There is an application for exception to loss of novelty

本発明は、留具に関する。さらに詳しく説明すると、本発明は、デザイン選択の幅が広い留具に関する。 The present invention relates to fasteners. More particularly, the present invention relates to fasteners with a wide range of design options.

例えば、ベルト等の一端につけ、他端をはめ入れて締める道具としてバックル等の留具がある。例えば、バックルには、カバンのショルダーベルトやリュックサックのチェストストラップに使用されるものがある。このようなバックルには、金属で製造されたものや合成樹脂で製造されたもの等様々なものがあるが、着脱操作が容易で不用意に外れない、サイドリリースバックルが多く利用されている。 For example, there is a fastener such as a buckle as a tool that is attached to one end of a belt or the like and the other end is fitted and tightened. For example, some buckles are used for shoulder belts of bags and chest straps of rucksacks. There are various types of such buckles, such as those made of metal and those made of synthetic resin, but side release buckles are often used because they are easy to attach and detach and do not come off accidentally.

例えば、不用意なプラグとソケットの離脱を確実に防止した上で、プラグとソケットの取外しが極めて容易、迅速に可能であり、また、ソケットの縁部等で指を痛めることもなく、更には、脱着操作時に持ち損ねが生じることのない、極めて優れた合成樹脂製のバックルの技術が知られている（例えば、特許文献１参照）。また、適切なガイド機能を確保しつつガイド面と係合部との摺動を緩和できるサイドリリースバックルの技術が知られている（例えば、特許文献２参照）。さらに、バックルに加えられた衝撃をプラグが吸収し、プラグの脚部の破損を防ぐバックル用のプラグそれを用いたバックルの技術が知られている（例えば、特許文献３参照）。 For example, it is possible to reliably prevent the unintentional disconnection of the plug and the socket, and it is possible to remove the plug and the socket very easily and quickly. , there is known a technique of an extremely excellent synthetic resin buckle that does not cause a failure to hold when attaching and detaching (see, for example, Patent Document 1). Also, there is known a technology of a side release buckle that can alleviate the sliding between the guide surface and the engaging portion while ensuring an appropriate guide function (see, for example, Patent Document 2). Further, there is known a buckle technology using a plug for a buckle that absorbs impact applied to the buckle and prevents breakage of the legs of the plug (see, for example, Patent Document 3).

しかし、特許文献１～３に示されたサイドリリースタイプのバックルは、左右の部分に凹凸ができてしまうため、デザイン選択の幅が狭まるという問題点がある。 However, the side-release type buckles disclosed in Patent Documents 1 to 3 have unevenness on the left and right portions, which narrows the range of design choices.

When the operating portion 40 is pulled, the inner leg portion 22 is pulled as shown in FIG. The male member 1 and the female member 2 are disengaged from each other by moving inward in the width direction from the joint portion 90 .

本例において、内脚部２２は、外脚部２１より長く形成されているため、内脚部２２と外脚部２１とが同様の長さの場合と比較して、内脚部２２が引っ張られたときの外脚部２１の幅方向内側への移動が大きくなる。一対の係合部３０は、一対の被係合部９０の位置から幅方向内側に大きく移動するため、雄部材１と雌部材２とが係合状態が確実に解除される。脚部２０は、第一補強部２３及び第二補強部２４が形成されることで、操作部４０に引っ張られても、脚部２０の形状が維持され形状が崩れにくい。一対の脚部２０は、第一補強部２３及び第二補強部２４が左右対称に形成されているため、操作部４０に引っ張られたとき、一対の脚部２０が同様の間隔で幅方向内側へ移動する。このため、一対の係合部３０の一方のみが被係合部９０から外れることがなくなり、雄部材１と雌部材２とが係合状態が確実に解除される。 In this example, since the inner leg portion 22 is formed longer than the outer leg portion 21, the inner leg portion 22 is pulled more than when the inner leg portion 22 and the outer leg portion 21 have the same length. The movement of the outer leg portion 21 to the inside in the width direction when it is pushed increases. Since the pair of engaging portions 30 largely moves inward in the width direction from the position of the pair of engaged portions 90, the engaged state between the male member 1 and the female member 2 is reliably released. Since the leg portion 20 is provided with the first reinforcing portion 23 and the second reinforcing portion 24 , the shape of the leg portion 20 is maintained even if the operation portion 40 pulls the leg portion 20 , and the shape does not easily collapse. Since the pair of leg portions 20 has the first reinforcing portion 23 and the second reinforcing portion 24 formed symmetrically, when the pair of leg portions 20 are pulled by the operation portion 40, the pair of leg portions 20 are arranged at the same intervals inward in the width direction. move to Therefore, only one of the pair of engaging portions 30 is prevented from being disengaged from the engaged portion 90, and the engaged state between the male member 1 and the female member 2 is reliably released.

さらに、操作部４０を引っ張ると、図６（ｂ）に示すように、一対の係合部３０が案内面６３に移動する。一対の脚部２０は、案内面６３に移動すると、一対の係合部３０が第二挿通路８０側に移動することを規制された状態で、一対の脚部２０の幅方向の間隔が拡がり、前方向Ｆ側に移動する。一対の脚部２０の弾性変形が解除されると、図６（ａ）に示す、解除状態の雄部材１及び雌部材２となる。このように雄部材１と雌部材２とから構成された留具ＢＫは、容易に係合状態を解除することができる。 Furthermore, when the operating portion 40 is pulled, the pair of engaging portions 30 move to the guide surface 63 as shown in FIG. 6(b). When the pair of leg portions 20 move to the guide surface 63, the gap in the width direction between the pair of leg portions 20 widens while the pair of engaging portions 30 is restricted from moving toward the second insertion passage 80. , moves forward in the F direction. When the elastic deformation of the pair of legs 20 is released, the male member 1 and the female member 2 in the released state shown in FIG. 6(a) are obtained. The fastener BK composed of the male member 1 and the female member 2 in this manner can be easily disengaged.

以上、本発明の実施の形態の説明を行ったが、本発明は、この実施の形態に限定されることはなく、本発明の目的、趣旨を逸脱しない範囲内で変更ができる。雄部材１の雄本体１０及び雌部材２の雌本体５０には、ベルトやその他の部材を取り付けても良いことはいうまでもない。留具ＢＫは、ポリアセタール樹脂で形成されているが、他の部材、例えば、金属等で形成されても良い。また、留具ＢＫをＡＢＳ樹脂で形成して、その表面に金属メッキを施して金属層を形成して、軽量化をすると共に表面に金属特有の高級感を表しても良い。さらに、雄部材１及び雌部材２は、同一の材料で形成されても良いが、別々の材料で形成されても良い。操作部４０は、脚部２０を引っ張り、脚部２０の幅方向の間隔を狭めるのであれば、どのような形状でも良い。例えば、操作部４０は、上方向又は下方向に形成され、前後にスライド移動することで、脚部２０の幅方向の間隔を狭めるボタンであっても良い。雄部材１の寸法及び雌部材２の寸法は、使用する部材に応じて適宜変更しても良い。 Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and modifications can be made without departing from the scope and spirit of the present invention. Needless to say, the male body 10 of the male member 1 and the female body 50 of the female member 2 may be attached with belts or other members. The fastener BK is made of polyacetal resin, but may be made of other material such as metal. Alternatively, the fastener BK may be made of ABS resin, and its surface may be plated with a metal to form a metal layer to reduce weight and give the surface a high-class appearance peculiar to metal. Furthermore, the male member 1 and the female member 2 may be made of the same material, or may be made of different materials. The operation part 40 may be of any shape as long as it pulls the leg part 20 and narrows the interval between the leg parts 20 in the width direction. For example, the operation part 40 may be a button that is formed in the upward or downward direction and slides back and forth to narrow the space between the legs 20 in the width direction. The dimensions of the male member 1 and the dimensions of the female member 2 may be appropriately changed according to the members to be used.
