（第１実施形態）
本発明の実施形態に係る留め具を図１〜３に示す。留め具は、段ボール、プラスチック製ボード、紙製シート、木製ボード、金属板などの平坦部材１に取り付けられる。平坦部材１は、例えばディスプレイ用のボックスやスタンド、陳列用のラックや棚といった什器を構成するものである。また、平坦部材１は、建物の壁、天井、パーテーションであってもよい。なお、留め具は１枚の平坦部材１に取り付けられるだけでなく、複数枚の平坦部材１を重ねて、各平坦部材１を固定するために留め具を取り付けてもよい。 (First Embodiment)
Fasteners according to an embodiment of the present invention are shown in FIGS. The fastener is attached to a flat member 1 such as a corrugated cardboard, a plastic board, a paper sheet, a wooden board, or a metal plate. The flat member 1 constitutes fixtures such as a box or stand for a display, a rack or a shelf for a display, and the like. Further, the flat member 1 may be a wall, a ceiling, or a partition of a building. In addition, the fastener may be attached not only to one flat member 1 but also to stack a plurality of flat members 1 and attach a fastener to fix each flat member 1.

留め具は、平板状のベース部２と、ベース部２に立設された軸部３と、軸部３の先端に開閉可能に設けられた左右一対の挟み部４とから構成され、ポリエチレン等のプラスチックにより一体的に成形される。ベース部２は、ほぼ正方形の矩形状に形成される。軸部３は、前後方向に細長く形成され、軸部３の先端側は基端側よりも細くなっている。平板状の挟み部４は、ヒンジ５により軸部３の先端に連結される。挟み部４の基端は、外側寄りがカットされた傾斜面になっている。挟み部４の基端の内側端が前後方向にわたって軸部３の先端の角につながっており、挟み部４は左右方向に開閉する。 The fastener is composed of a flat plate-shaped base portion 2, a shaft portion 3 erected on the base portion 2, and a pair of left and right sandwiching portions 4 provided at the tip of the shaft portion 3 so as to be openable and closable. It is integrally molded with the plastic of. The base portion 2 is formed in a substantially square rectangular shape. The shaft portion 3 is formed elongated in the front-rear direction, and the tip end side of the shaft portion 3 is thinner than the base end side. The flat plate-shaped sandwiching portion 4 is connected to the tip of the shaft portion 3 by a hinge 5. The base end of the sandwiching portion 4 is an inclined surface with the outer side cut off. The inner end of the base end of the sandwiching portion 4 is connected to the corner of the tip of the shaft portion 3 in the front-rear direction, and the sandwiching portion 4 opens and closes in the left-right direction.

そして、留め具は、挟み部４を開いた状態に保持する左右一対の保持部６と、保持部６を係止するロック部７とを有する。保持部６は、挟み部４の基端の外側端にヒンジ８により連結される。ロック部７は、ベース部２の左右両側に設けられる。図４〜６に示すように、左右の挟み部４が互いに離れるように開いた状態のときに、保持部６がロック部７に係止される。 The fastener has a pair of left and right holding portions 6 for holding the sandwiching portion 4 in an open state, and a locking portion 7 for locking the holding portion 6. The holding portion 6 is connected to the outer end of the base end of the sandwiching portion 4 by a hinge 8. The lock portions 7 are provided on both the left and right sides of the base portion 2. As shown in FIGS. 4 to 6, the holding portion 6 is locked to the locking portion 7 when the left and right sandwiching portions 4 are opened so as to be separated from each other.

保持部６は、Ｌ字状に形成され、保持部６の上部１０は軸部３と平行とされ、下部１１はベース部２と平行とされる。保持部６の上部１０の先端側は、内側寄りがカットされた傾斜面になっている。保持部６の先端の外側端が挟み部４の基端の外側端につながっている。図１に示すように、挟み部４が閉じた状態のとき、挟み部４の基端の傾斜面と保持部６の先端の傾斜面とが対向し、保持部６の上部１０は、軸部３の先端側に対向している。図２に示すように、挟み部４が開いた状態のとき、挟み部４はベース部２と平行になり、保持部６の上部１０は軸部３に接し、下部１１はベース部２に接する。 The holding portion 6 is formed in an L shape, the upper portion 10 of the holding portion 6 is parallel to the shaft portion 3, and the lower portion 11 is parallel to the base portion 2. The tip end side of the upper portion 10 of the holding portion 6 is an inclined surface with the inward side cut off. The outer end of the tip of the holding portion 6 is connected to the outer end of the base end of the sandwiching portion 4. As shown in FIG. 1, when the sandwiching portion 4 is closed, the inclined surface at the base end of the sandwiching portion 4 and the inclined surface at the tip of the holding portion 6 face each other, and the upper portion 10 of the holding portion 6 is a shaft portion. It faces the tip side of 3. As shown in FIG. 2, when the sandwiching portion 4 is open, the sandwiching portion 4 is parallel to the base portion 2, the upper portion 10 of the holding portion 6 is in contact with the shaft portion 3, and the lower portion 11 is in contact with the base portion 2. ..

保持部６の下部１１に、ベース部２に向かって突出した係止爪１２が左右方向に形成されている。ロック部７は、係止爪１２を嵌め込む嵌合孔１３を有する。嵌合孔１３は、先端が山形状に形成された係止爪１２に対応して左右方向に形成され、段差を有する。係止爪１２が嵌合孔１３に挿入されると、係止爪１２の先端が弾性変形しながら係止爪１２は嵌合孔１３に嵌まる。これにより、保持部６はベース部２に固定され、挟み部４は開いた状態に保持される。また、嵌合孔１３に係止された係止爪１２は、ベース部２の外部から係止を解除可能とされる。 A locking claw 12 projecting toward the base portion 2 is formed in the lower portion 11 of the holding portion 6 in the left-right direction. The lock portion 7 has a fitting hole 13 into which the locking claw 12 is fitted. The fitting hole 13 is formed in the left-right direction corresponding to the locking claw 12 whose tip is formed in a mountain shape, and has a step. When the locking claw 12 is inserted into the fitting hole 13, the locking claw 12 fits into the fitting hole 13 while the tip of the locking claw 12 is elastically deformed. As a result, the holding portion 6 is fixed to the base portion 2, and the sandwiching portion 4 is held in an open state. Further, the locking claw 12 locked in the fitting hole 13 can be released from the outside of the base portion 2.

留め具が取り付けられる平坦部材１には、取付孔１４が形成される。取付孔１４は、挟み部４の形状に対応して矩形状に形成される。留め具を平坦部材１の外側から取付孔１４に押し込むと、図１に示すように、閉じた状態の挟み部４が取付孔１４に挿通される。保持部６の上部１０が取付孔１４を通過すると、保持部６の下部１１が平坦部材１に接触し、保持部６はこれ以上進まなくなる。さらに留め具を押し込むと、図３に示すように、軸部３は押し込まれるので、保持部６と挟み部４をつなぐヒンジ８を中心にして、２つの挟み部４が左右に開く。このとき、保持部６の上部１０が少し傾く。軸部３の先細になった先端側の周囲にはスペースができるので、保持部６は傾くことができる。そのまま留め具を押し込むと、図２に示すように、挟み部４が開いて、平坦部材１に当接するとともに、ベース部２が保持部６の下部１１に近づき、係止爪１２が嵌合孔１３に嵌まり込む。 A mounting hole 14 is formed in the flat member 1 to which the fastener is mounted. The mounting hole 14 is formed in a rectangular shape corresponding to the shape of the sandwiching portion 4. When the fastener is pushed into the mounting hole 14 from the outside of the flat member 1, the closed sandwiched portion 4 is inserted into the mounting hole 14, as shown in FIG. When the upper portion 10 of the holding portion 6 passes through the mounting hole 14, the lower portion 11 of the holding portion 6 comes into contact with the flat member 1, and the holding portion 6 does not advance any further. When the fastener is further pushed in, as shown in FIG. 3, the shaft portion 3 is pushed in, so that the two sandwiching portions 4 open to the left and right centering on the hinge 8 connecting the holding portion 6 and the sandwiching portion 4. At this time, the upper portion 10 of the holding portion 6 is slightly tilted. Since a space is formed around the tapered tip side of the shaft portion 3, the holding portion 6 can be tilted. When the fastener is pushed in as it is, as shown in FIG. 2, the sandwiching portion 4 opens and comes into contact with the flat member 1, the base portion 2 approaches the lower portion 11 of the holding portion 6, and the locking claw 12 enters the fitting hole. It fits into 13.

このように留め具を押し込むことにより、挟み部４とベース部２とが平坦部材１を挟み込んで留め具は平坦部材１に取り付けられる。このとき、ベース部２を引っ張っても、係止爪１２が嵌合孔１３に嵌まっているので、保持部６は動かず、挟み部４は開いた状態を保持する。したがって、留め具は強固に平坦部材１に取り付けられる。また、取付孔１４が矩形状であるので、円形の取付孔１４に比べて挟み部４およびベース部２と平坦部材１との接触面積が増え、平坦部材１をしっかりと挟み付けることができる。 By pushing the fastener in this way, the sandwiching portion 4 and the base portion 2 sandwich the flat member 1 and the fastener is attached to the flat member 1. At this time, even if the base portion 2 is pulled, the locking claw 12 is fitted in the fitting hole 13, so that the holding portion 6 does not move and the sandwiching portion 4 is held in the open state. Therefore, the fastener is firmly attached to the flat member 1. Further, since the mounting hole 14 has a rectangular shape, the contact area between the sandwiching portion 4 and the base portion 2 and the flat member 1 is increased as compared with the circular mounting hole 14, and the flat member 1 can be firmly sandwiched.

ここで、留め具を取り外せるように、係止爪１２の先端は平坦部材１の外部に露出しているので、係止爪１２を外すことができる。すなわち、係止爪１２を強く押しながらベース部２を引っ張ると、係止爪１２の先端が弾性変形して、係止爪１２が嵌合孔１３から抜ける。すると、軸部３が取付孔１４から抜けて、保持部６も抜ける。保持部６の移動に連動して、左右の挟み部４は閉じ、挟み部４が取付孔１４から抜け出し、留め具を平坦部材１から取り外すことができる。 Here, since the tip of the locking claw 12 is exposed to the outside of the flat member 1 so that the fastener can be removed, the locking claw 12 can be removed. That is, when the base portion 2 is pulled while strongly pressing the locking claw 12, the tip of the locking claw 12 is elastically deformed and the locking claw 12 comes out of the fitting hole 13. Then, the shaft portion 3 comes out of the mounting hole 14, and the holding portion 6 also comes out. In conjunction with the movement of the holding portion 6, the left and right sandwiching portions 4 are closed, the sandwiching portion 4 comes out of the mounting hole 14, and the fastener can be removed from the flat member 1.

他の形態の留め具を図４に示す。留め具のベース部２が円板になっている。その他の構成は、上記と同じ構成である。留め具を取り付ける平坦部材１に応じて、ベース部２を矩形か円形かを選択することができる。 Other forms of fasteners are shown in FIG. The base portion 2 of the fastener is a disk. Other configurations are the same as above. The base portion 2 can be selected to be rectangular or circular depending on the flat member 1 to which the fastener is attached.

（第２実施形態）
本実施形態の留め具を図５〜７に示す。留め具は、平板状のベース部２と、ベース部２に立設された左右一対の軸部３と、各軸部３の先端に開閉可能に設けられた左右一対の平板状の挟み部４とから構成され、ポリエチレン等のプラスチックにより一体的に成形される。ベース部２は、円形に形成される。２つの軸部３が対向して配置され、ベース部２にヒンジ２０により連結され、軸部３は左右方向に傾く。軸部３は、前後方向に細長く形成され、内側に向かって凸となる台形状に形成される。 (Second Embodiment)
The fasteners of this embodiment are shown in FIGS. 5 to 7. The fasteners are a flat plate-shaped base portion 2, a pair of left and right shaft portions 3 erected on the base portion 2, and a pair of left and right flat plate-shaped sandwiching portions 4 provided at the tip of each shaft portion 3 so as to be openable and closable. It is composed of and integrally molded from plastic such as polyethylene. The base portion 2 is formed in a circular shape. The two shaft portions 3 are arranged so as to face each other, are connected to the base portion 2 by a hinge 20, and the shaft portion 3 is tilted in the left-right direction. The shaft portion 3 is formed in an elongated shape in the front-rear direction, and is formed in a trapezoidal shape that is convex inward.

挟み部４は、円板を分割した形状とされ、互いに対向する挟み部４の内周縁はＳ字の凹凸状に形成され、各挟み部４は、凸部２１と凹部２２を有する。挟み部４は、左右方向の中央においてヒンジ５により軸部３の先端に連結される。図５に示す閉じた状態のとき、左右の挟み部４は、軸部３と平行になるように対向している。左右の挟み部４は、閉じた状態から左右方向に開閉可能とされ、先端を外側に向けて開く。図７に示す開いた状態のとき、左右の挟み部４は、互いに近接離間するように移動可能とされる。開いた左右の挟み部４が互いに内側に向かって近づくと、図６に示すように、各挟み部４の一部が重なり合って合体する。すなわち、一方の挟み部４の凸部２１が他方の挟み部４の凹部２２に重なる。 The sandwiching portion 4 has a shape in which a disk is divided, and the inner peripheral edges of the sandwiching portions 4 facing each other are formed in an S-shaped uneven shape, and each sandwiching portion 4 has a convex portion 21 and a concave portion 22. The sandwiching portion 4 is connected to the tip of the shaft portion 3 by a hinge 5 at the center in the left-right direction. In the closed state shown in FIG. 5, the left and right sandwiching portions 4 face each other so as to be parallel to the shaft portion 3. The left and right sandwiching portions 4 can be opened and closed in the left-right direction from the closed state, and the tips thereof are opened outward. In the open state shown in FIG. 7, the left and right sandwiching portions 4 are movable so as to be close to each other. When the left and right sandwiched portions 4 that are opened approach each other inward, a part of each sandwiched portion 4 overlaps and coalesces as shown in FIG. That is, the convex portion 21 of one sandwiching portion 4 overlaps the concave portion 22 of the other sandwiching portion 4.

そして、一方の挟み部４に、挟み部４の重なった状態を保持する保持部２３が設けられ、他方の挟み部４に、保持部２３を係止するロック部２４が設けられる。凸部２１に保持部２３が設けられ、凹部２２にロック部２４が設けられ、挟み部４の一部が重なり合ったとき、保持部２３がロック部２４に係止される。保持部２３は突起とされ、ロック部２４は凹みとされ、突起が凹みに嵌まることにより、保持部２３は係止される。 Then, one sandwiching portion 4 is provided with a holding portion 23 for holding the overlapping state of the sandwiching portions 4, and the other sandwiching portion 4 is provided with a locking portion 24 for locking the holding portion 23. The holding portion 23 is provided on the convex portion 21, the locking portion 24 is provided on the concave portion 22, and when a part of the sandwiching portion 4 overlaps, the holding portion 23 is locked to the locking portion 24. The holding portion 23 is a protrusion, the lock portion 24 is a recess, and the holding portion 23 is locked by fitting the protrusion into the recess.

留め具を平坦部材１の外側から取付孔１４に押し込むと、図５に示すように、閉じた状態の挟み部４が取付孔１４に挿通される。軸部３が取付孔１４に入ると、ベース部２が平坦部材１に接触する。次に、平坦部材１の内側に突出した各挟み部４をそれぞれ外側に向けて倒すと、図７に示すように、左右の挟み部４が開く。左右の挟み部４が近づくように、挟み部４を内側に向けて押す。一方の凸部２１と他方の凹部２２が重なり、図６に示すように、左右の挟み部４が合体する。このとき、凸部２１の保持部２３が凹部２２のロック部２４に係止される。重なった状態の挟み部４は、平坦部材１に接触し、ベース部２とにより平坦部材１を挟み込む。 When the fastener is pushed into the mounting hole 14 from the outside of the flat member 1, the closed sandwiched portion 4 is inserted into the mounting hole 14, as shown in FIG. When the shaft portion 3 enters the mounting hole 14, the base portion 2 comes into contact with the flat member 1. Next, when each of the sandwiched portions 4 protruding inward of the flat member 1 is tilted outward, the left and right sandwiched portions 4 open as shown in FIG. 7. Push the sandwiching portion 4 inward so that the left and right sandwiching portions 4 approach each other. One convex portion 21 and the other concave portion 22 overlap each other, and as shown in FIG. 6, the left and right sandwiched portions 4 are united. At this time, the holding portion 23 of the convex portion 21 is locked to the lock portion 24 of the concave portion 22. The overlapping sandwiching portions 4 come into contact with the flat member 1 and sandwich the flat member 1 with the base portion 2.

このようにして、留め具は平坦部材１に取り付けられる。このとき、ベース部２を引っ張っても、互いの挟み部４の突起が凹みに嵌まっているので、左右の挟み部４は動かず、挟み部４は重なった状態を保持する。したがって、留め具は強固に平坦部材１に取り付けられる。また、取付孔１４が矩形状であるので、円形の留め具であっても、ベース部２や挟み部４を大径にすることなく、平坦部材１に接触させることができる。 In this way, the fastener is attached to the flat member 1. At this time, even if the base portion 2 is pulled, the protrusions of the sandwiching portions 4 are fitted in the recesses, so that the left and right sandwiching portions 4 do not move and the sandwiching portions 4 maintain the overlapped state. Therefore, the fastener is firmly attached to the flat member 1. Further, since the mounting hole 14 has a rectangular shape, even a circular fastener can be brought into contact with the flat member 1 without making the base portion 2 and the sandwiching portion 4 having a large diameter.

ここで、留め具を取り外したい場合、左右の挟み部４を外側に押し広げると、挟み部４の突起が凹みから抜け出し、保持部２３の係止が解除される。左右の挟み部４は離れ、挟み部４を閉じることができる。閉じた状態の挟み部４が取付孔１４から抜け出し、留め具を平坦部材１から取り外すことができる。 Here, when it is desired to remove the fastener, when the left and right sandwiching portions 4 are pushed outward, the protrusions of the sandwiching portion 4 come out of the recess and the holding portion 23 is released from the lock. The left and right sandwiched portions 4 are separated, and the sandwiched portion 4 can be closed. The sandwiched portion 4 in the closed state comes out of the mounting hole 14, and the fastener can be removed from the flat member 1.
