Description

本願発明は、板材等を構造物に取り付けて固定するための留め具に関する。従来から、あらゆる形状の板材を、構造物の一部(被取付部材)に留め具によって取り付けて固定していた。例えば、家具や箱状の入れ物等の構造物の一部に、留め具を介してパネル等の板材等を固定することで、その構造物の底面や側面等を形成していた。   The present invention relates to a fastener for attaching and fixing a plate material or the like to a structure. Conventionally, plate materials of all shapes have been attached and fixed to a part of the structure (attached member) with a fastener. For example, by fixing a plate material such as a panel to a part of a structure such as furniture or a box-like container via a fastener, the bottom surface or side surface of the structure is formed.

このような従来技術として、例えば、特許文献1に示す箱状のコンテナに使用される留め具が知られている。この特許文献1のコンテナは、四角枠形状の上フレームと、有底形状の底フレームと、上フレームと底フレームの間に連結される側板(板材)とによって、組み立て可能に構成されたものである。そして、底フレームの表面には、樹脂製のピン(留め具)が複数形成されており、そのピンに底板の貫通孔を挿入し、その後、ピンの端部を溶融することで、底板を底フレームに固着させていた。   As such a conventional technique, for example, a fastener used for a box-shaped container shown in Patent Document 1 is known. The container of Patent Document 1 is configured to be assembled by a square frame-shaped upper frame, a bottomed bottom frame, and a side plate (plate material) connected between the upper frame and the bottom frame. is there. A plurality of resin pins (fasteners) are formed on the surface of the bottom frame, and through holes of the bottom plate are inserted into the pins, and then the end portions of the pins are melted so that the bottom plate is fixed to the bottom frame. It was fixed to the frame.

しかしながら、上記特許文献1のコンテナは、ピンの端部を溶融させるために、例えば、熱板等をピンに押し当てる必要があり、コンテナを組み立てられる場所は、熱板等のピンを溶融させることのできる固着用装置が備えられた場所に限定されてしまう。   However, in order to melt the end portion of the pin, for example, the container of Patent Document 1 needs to press a hot plate or the like against the pin, and the place where the container can be assembled melts the pin such as the hot plate. It will be limited to the place where the fixing device which can do is provided.

また、底フレームと底板は、溶融したピンによって強固に一体化するので、仮に、底板が破損した場合は、板材のみを取り外して交換することは難しく、コンテナ自体を破棄しなければならない場合もあり、非常に不便でもあった。   Also, since the bottom frame and the bottom plate are firmly integrated with the melted pins, if the bottom plate is damaged, it is difficult to remove and replace only the plate material, and the container itself may need to be discarded. It was also very inconvenient.

実開平6−32324号Utility Kaihei 6-32324

そこで、本願発明は、上記問題に鑑み、固着用装置を別途必要とすることなく、構造物の一部に、板材等を強固に固定することのできる留め具を提供する。   Therefore, in view of the above problems, the present invention provides a fastener capable of firmly fixing a plate material or the like to a part of a structure without separately requiring a fixing device.

上記課題を解決するために、本願発明の請求項1に留め具は、本体部と、当該本体部の上端側に頭部を備え、前記本体部を被取付部材の開口部に挿入し、当該被取付部材と前記頭部とによって、板材を挟んで固定する留め具であって、前記本体部の一方の両側の側面には、傾斜した第一係合面が形成された係合弾性板を、前記本体部の他方の両側の側面には、第二係合面が形成された係合弾性部を、備え、前記第一係合面は、前記開口部の内面の一方の両側に設けられた第一係合突起と、前記第二係合面は、前記開口部の内面の他方の両側に設けられた第二係合突起と、係合し、前記第一係合突起の先端同士の長さは、前記第一係合面の下端同士の長さよりも短くなっており、前記第一係合面の上端には、係合段部が設けられ、当該係合段部に、前記第一係合突起が当接可能なことを特徴とする。 In order to solve the above-mentioned problem, the fastener according to claim 1 of the present invention includes a main body portion and a head on the upper end side of the main body portion, and the main body portion is inserted into the opening of the attached member. the said head and the mounting member, a fastener for securing across the plate, one on either side of the side surface of the body portion, the engaging elastic plate first engagement surface inclined is formed , on the other sides of the side surface of the body portion, the engaging elastic portion where the second engaging surface is formed, wherein the first engagement surface is provided on one sides of the inner surface of the opening a first engagement protrusions, said second engaging surface includes a second engagement projection provided on the other sides of the inner surface of the opening, and the engagement, the tips of the first engagement protrusion The length is shorter than the length between the lower ends of the first engagement surface, and an engagement step portion is provided at the upper end of the first engagement surface. The first engaging protrusion is equal to or capable of contacting.

上記特徴によれば、従来のように、固着用措置によってピンを溶融させて固着させなくても、係合弾性板と第一係合突起との係合と、係合弾性部と第二係合突起との係合によって、板材を被取付部材(枠体)に十分に固定することができる。また、係合弾性板の傾斜した第一係合面に第一係合突起が係合することから、留め具は側方及び上方にガタつきなく係止され、さらに、係合弾性板の弾性によって、その係合状態を維持することができる。なお、「第一係合面」及び「第二係合面」は、その表面が平坦面、湾曲面、及び凹凸面等の種々の形状を含む。   According to the above feature, the engagement between the engagement elastic plate and the first engagement protrusion, the engagement elastic portion, and the second engagement can be achieved without the need to melt and fix the pin by a fixing measure as in the conventional case. By engaging with the mating protrusion, the plate material can be sufficiently fixed to the member to be attached (frame body). In addition, since the first engagement protrusion is engaged with the inclined first engagement surface of the engagement elastic plate, the fastener is locked to the side and the upper side without rattling, and the elasticity of the engagement elastic plate is further increased. Thus, the engaged state can be maintained. The “first engagement surface” and the “second engagement surface” include various shapes such as a flat surface, a curved surface, and an uneven surface.

さらに、本願発明の請求項3に係る留め具は、前記第一係合面には、係合段部が設けられ、当該係合段部に、前記第一係合突起が当接可能なことを特徴とする。 Further, in the fastener according to claim 3 of the present invention, an engagement step portion is provided on the first engagement surface, and the first engagement protrusion can contact the engagement step portion. It is characterized by.

上記特徴によれば、留め具が側方へずれても、第一係合突起が係合段部に当接して引っ掛かるので、係合弾性板と第一係合突起との係合が維持される。さらに、第一係合突起が係合段部に係合しているので、留め具が上方へ引き抜かれそうになっても、係合弾性板が、第一係合突起と留め具の間で、突っ張り棒のように作用して、上方への外力に強く対抗するから、留め具は外れない。   According to the above feature, even when the fastener is displaced to the side, the first engagement projection is brought into contact with the engagement step portion and is hooked, so that the engagement between the engagement elastic plate and the first engagement projection is maintained. The Furthermore, since the first engagement protrusion is engaged with the engagement step portion, even if the fastener is about to be pulled upward, the engagement elastic plate is not between the first engagement protrusion and the fastener. The fastener does not come off because it acts like a tension rod and strongly opposes the upward external force.

さらに、本願発明の請求項4に係る留め具は、前記開口部の一部に当接可能で、当該開口部と前記留め具との距離を一定に保つことのできる移動防止部を備えたことを特徴とする。 Furthermore, the fastener according to claim 4 of the present invention includes a movement preventing portion that can contact a part of the opening and can keep the distance between the opening and the fastener constant. It is characterized by.

上記特徴によれば、留め具が側方へ押されて移動しても、移動防止部が開口部に当接するので、留め具はそれ以上移動できない。つまり、移動防止部によって、開口部と留め具との距離を一定に保つことができるので、係合弾性板が第一係合突起から外れてしまうのを防止できる。また、開口部と留め具との距離が一定に保たれるので、その範囲内で係合弾性板が無理なく弾性変形することができ、係合弾性板が過剰に変形して破損してしまうことが防止されている。   According to the above feature, even if the fastener is pushed to the side and moved, the movement preventing portion comes into contact with the opening, and thus the fastener cannot move any further. That is, since the distance between the opening and the fastener can be kept constant by the movement preventing portion, it is possible to prevent the engagement elastic plate from being detached from the first engagement protrusion. Further, since the distance between the opening and the fastener is kept constant, the engagement elastic plate can be elastically deformed without difficulty within the range, and the engagement elastic plate is excessively deformed and damaged. It is prevented.

本願発明の留め具は、固着用装置を別途必要とすることなく、構造物の一部に、板材等を強固に固定することができる。   The fastener of the present invention can firmly fix a plate material or the like to a part of the structure without requiring a separate fixing device.

以下に、本願発明の実施の形態について、図面を用いて説明する。   Embodiments of the present invention will be described below with reference to the drawings.

まず、図1には、本願発明の留め具100を示す。図に示すように、留め具100は、四方が左側面111、右側面112、前側面113、及び後側面114で囲まれた中空状の本体部110と、その上端側に、平面視略長方形の平坦な薄板状の頭部120を有している。   First, FIG. 1 shows a fastener 100 of the present invention. As shown in the figure, the fastener 100 has a hollow main body 110 surrounded by a left side surface 111, a right side surface 112, a front side surface 113, and a rear side surface 114 on four sides, and a substantially rectangular shape in plan view on the upper end side thereof. A flat thin plate-like head 120.

本体部110の相対する側面の左側面111と右側面112には、それぞれ係合弾性板130が設けられており、各係合弾性板130の下端側は、各側面の下端側と連結されている。また、この係合弾性板130は、ある程度の弾性を備えた、長尺板形状をしており、先端側に外力が加えられると、湾曲して変形する。さらに、この係合弾性板130の先端側には、表面が平坦であって、全体が傾斜した第一係合面131が形成され、その傾斜した第一係合面131の上端から突出するように係合段部132が連続して形成されている。なお、この両側の係合弾性板130の先端間の長さは、外力が加えられてない通常の状態で、L1となっている。   Engagement elastic plates 130 are respectively provided on the left side surface 111 and the right side surface 112 of the opposing side surfaces of the main body 110, and the lower end side of each engagement elastic plate 130 is connected to the lower end side of each side surface. Yes. The engagement elastic plate 130 has a long plate shape with a certain degree of elasticity, and is bent and deformed when an external force is applied to the distal end side. Further, a first engagement surface 131 having a flat surface and an overall inclination is formed on the distal end side of the engagement elastic plate 130 so as to protrude from the upper end of the inclined first engagement surface 131. The engaging step 132 is continuously formed. In addition, the length between the front ends of the engagement elastic plates 130 on both sides is L1 in a normal state where no external force is applied.

同様に、本体部110の相対する側面の前側面113と後側面114には、それぞれ係合弾性部140が設けられており、各係合弾性部140の下端側は、各側面の下端側と連結されている。この係合弾性部140は、ある程度の弾性を有しており、先端側に外力が加えられると、湾曲して変形する。また、この係合弾性部140の先端側には、表面が平坦であって、水平方向へ広がる第二係合面141が形成されている。なお、この両側の係合弾性部140の先端間の長さは、外力が加えられてない通常の状態で、L2となっている。   Similarly, an engagement elastic portion 140 is provided on each of the front side surface 113 and the rear side surface 114 of the opposite side surfaces of the main body 110, and the lower end side of each engagement elastic portion 140 is the lower end side of each side surface. It is connected. The engagement elastic portion 140 has a certain degree of elasticity, and is bent and deformed when an external force is applied to the distal end side. A second engagement surface 141 having a flat surface and extending in the horizontal direction is formed on the distal end side of the engagement elastic portion 140. In addition, the length between the front ends of the engagement elastic portions 140 on both sides is L2 in a normal state where no external force is applied.

また、係合弾性板130が設けられた左側面111と右側面112側には、それぞれ移動防止部150が形成されている。この移動防止部150は、各側面から一定の距離をおいて、背面をリブ151で支持されると共に、上端が頭部120の裏面に固定されている。   Moreover, the movement prevention part 150 is each formed in the left side 111 and the right side 112 side in which the engagement elastic board 130 was provided. The movement preventing unit 150 is supported by a rib 151 at a certain distance from each side surface, and has an upper end fixed to the back surface of the head 120.

なお、留め具100は合成樹脂製であり、金型によって一体成形されている。また、金型から留め具100を抜きやすくするために、抜き出し用ピンを当接させる突起等を、頭部120の裏面中央付近に設けるなど、適宜、変更することできる。   The fastener 100 is made of synthetic resin and is integrally formed by a mold. Further, in order to make it easier to remove the fastener 100 from the mold, it is possible to make appropriate changes, for example, by providing a protrusion that abuts the extraction pin near the center of the back surface of the head 120.

次に、図2(a)には、本願発明の留め具100を使用する対象の一例であるコンテナCを示す。このコンテナCは、枠状に組まれた被取付部材200に板材Tを取り付けて、四方と底面が板材Tで囲まれた箱状に形成されており、上方から内部に製品等を収容して運搬するのに利用される。また、板材Tの各辺に沿って、留め具100が複数取り付けられ、板材Tが被取付部材200に強固に固定されている。なお、図では、説明の都合上、底面部分の板材Tのみに留め具100が示してあるが、四方の側面部分の板材Tも不図示の留め具によって、同様に被取付部材200に固定されている。   Next, FIG. 2 (a) shows a container C which is an example of an object using the fastener 100 of the present invention. The container C is formed in a box shape in which a plate material T is attached to a member 200 to be mounted in a frame shape, and the four sides and the bottom surface are surrounded by the plate material T. Used for transportation. A plurality of fasteners 100 are attached along each side of the plate material T, and the plate material T is firmly fixed to the attached member 200. In the drawing, for convenience of explanation, the fastener 100 is shown only on the bottom surface portion of the plate material T, but the plate material T on the four side surface portions is similarly fixed to the attached member 200 by a fastener (not shown). ing.

具体的には、被取付部材200に板材Tを取り付ける際には、図2(b)に示すように、被取付部材200の開口部210へ、留め具100の本体部110を挿入する。詳しくは後述するが、本体部110を挿入すると、開口部210の内面の第一係合突起220と第二係合突起230に、本体部110の係合弾性板130と係合弾性部140がそれぞれ係合する。そして、板材Tは、留め具100の頭部120と被取付部材200とに挟まれて固定されることになる。   Specifically, when the plate member T is attached to the attached member 200, the main body 110 of the fastener 100 is inserted into the opening 210 of the attached member 200 as shown in FIG. As will be described in detail later, when the main body part 110 is inserted, the engagement elastic plate 130 and the engagement elastic part 140 of the main body part 110 are formed on the first engagement protrusion 220 and the second engagement protrusion 230 on the inner surface of the opening 210. Engage each. Then, the plate material T is sandwiched and fixed between the head 120 of the fastener 100 and the attached member 200.

また、コンテナCの内部に製品が大量に収容されると、底面の中央軸Mに向かって荷重がかかる。そのため、図2(b)に示すように、第二係合突起230がコンテナCの底面の中央軸Mに平行になるように配置するのが好ましい。その理由は、後述するように、第二係合突起230は、留め具100の係合弾性部140の第二係合面141と面接触して、強い係合状態にあるので、この荷重に十分耐えることができ、留め具100が外れるのを効果的に防止できるからである。   Further, when a large amount of products are stored in the container C, a load is applied toward the central axis M on the bottom surface. Therefore, as shown in FIG. 2B, it is preferable that the second engagement protrusion 230 is arranged so as to be parallel to the central axis M on the bottom surface of the container C. The reason is that, as will be described later, the second engagement protrusion 230 is in strong contact with the second engagement surface 141 of the engagement elastic portion 140 of the fastener 100, so It is because it can endure enough and can effectively prevent the fastener 100 from coming off.

次に、図3では、開口部210の構造について詳しく説明する。開口部210は、被取付部材200の一部が上方へ立ち上がって、水平断面が略長方形の筒状に形成された壁部211の内側部分である。そして、開口部210は、留め具100の本体部110が挿入できる形状に設定されると共に、その上側内面に第一係合突起220と第二係合突起230を設けている。なお、板材Tには壁部211が挿入できる貫通孔が開けられているので、図3に示すように、その貫通孔に壁部211が嵌め込まれて、開口部210の上端と板材Tの上面とが同一平面上になっている。なお、本実施例のように、開口部210の上端と板材Tの上面とが同一平面上に揃う状態に限定されることはなく、開口部210の上端と板材Tの上面の高さが異なっても良い。   Next, in FIG. 3, the structure of the opening 210 will be described in detail. The opening portion 210 is an inner portion of the wall portion 211 formed in a cylindrical shape having a substantially rectangular horizontal section, with a part of the attached member 200 rising upward. And the opening part 210 is set in the shape which can insert the main-body part 110 of the fastener 100, The 1st engagement protrusion 220 and the 2nd engagement protrusion 230 are provided in the upper inner surface. Since the plate member T has a through hole into which the wall portion 211 can be inserted, as shown in FIG. 3, the wall portion 211 is fitted into the through hole, and the upper end of the opening 210 and the upper surface of the plate member T are inserted. Are on the same plane. Note that the upper end of the opening 210 and the upper surface of the plate material T are not limited to the same plane as in the present embodiment, and the height of the upper end of the opening 210 and the upper surface of the plate material T are different. May be.

図3(a)は、開口部210の長側方向の断面を示しており(図2(b)のA―A断面)、開口部210の相対する内面に第一係合突起220が設けられている。第一係合突起220は、上方から下方へ向けて傾斜する傾斜面221と、その傾斜面211の先端222から連続し、水平方向へ向かう平坦面223からなる。そして、この第一係合突起220は、留め具100の係合弾性板130に係合するもので、この第一係合突起220の先端間の長さL3は、係合弾性板130の先端間の長さL1(図1(b)参照)よりも短く設定されている。したがって、係合弾性板130と第一係合突起220とは確実に係合することができるのである。   FIG. 3A shows a cross section in the long side direction of the opening 210 (AA cross section in FIG. 2B), and the first engagement protrusion 220 is provided on the inner surface facing the opening 210. ing. The first engagement protrusion 220 includes an inclined surface 221 inclined from the upper side to the lower side, and a flat surface 223 that continues from the tip 222 of the inclined surface 211 and extends in the horizontal direction. The first engagement protrusion 220 is engaged with the engagement elastic plate 130 of the fastener 100, and the length L3 between the tips of the first engagement protrusion 220 is the tip of the engagement elastic plate 130. It is set shorter than the length L1 between them (see FIG. 1B). Therefore, the engagement elastic plate 130 and the first engagement protrusion 220 can be reliably engaged.

また、図3(b)は、開口部210の短側方向の断面を示しており(図2(b)のB―B断面)、開口部210の相対する内面に第二係合突起230が設けられている。第二係合突起230は、上方から下方へ向けて傾斜する傾斜面231と、その傾斜面231の先端232から連続し、水平方向へ向かう、表面が平坦な係合面233からなる。この第二係合突起230は、留め具100の係合弾性部140に係合するもので、この第二係合突起230の先端間の長さL4は、係合弾性部140の先端間の長さL2(図1(c)参照)よりも短く設定されている。したがって、係合弾性部140と第二係合突起230とは確実に係合することができるのである。   FIG. 3B shows a cross section in the short side direction of the opening 210 (cross section BB in FIG. 2B), and the second engaging projection 230 is formed on the inner surface facing the opening 210. Is provided. The second engaging protrusion 230 includes an inclined surface 231 inclined from the upper side to the lower side, and an engaging surface 233 that is continuous from the tip 232 of the inclined surface 231 and has a flat surface in the horizontal direction. The second engagement protrusion 230 is engaged with the engagement elastic portion 140 of the fastener 100, and the length L4 between the distal ends of the second engagement protrusion 230 is between the distal ends of the engagement elastic portions 140. The length is set shorter than the length L2 (see FIG. 1C). Therefore, the engagement elastic part 140 and the second engagement protrusion 230 can be reliably engaged.

なお、開口部210は、被取付部材200と一体成形されているが、開口部210のみを別体として形成して、被取付部材200に取り付ける構造としてもよい。また、被取付部材200及び開口部210は合成樹脂等で成形されており、開口部210の第一係合突起220は、係合弾性板130の弾性変形に耐えうるように、係合弾性板130よりも高い剛性を備え、一方、第二係合突起230は、係合弾性部140の弾性変形に耐えうるように、係合弾性部140よりも高い剛性を備える。   In addition, although the opening part 210 is integrally formed with the to-be-attached member 200, it is good also as a structure attached to the to-be-attached member 200 by forming only the opening part 210 as a different body. The attached member 200 and the opening 210 are formed of a synthetic resin or the like, and the first engagement protrusion 220 of the opening 210 is adapted to withstand the elastic deformation of the engagement elastic plate 130. On the other hand, the second engagement protrusion 230 has a rigidity higher than that of the engagement elastic part 140 so as to withstand elastic deformation of the engagement elastic part 140.

では、次に、図4を参照して、開口部210に留め具100を挿入して、留め具100と被取付部材200とで板材Tを挟んで固定する態様について説明する。   Next, a mode in which the fastener 100 is inserted into the opening 210 and the plate member T is sandwiched and fixed between the fastener 100 and the attachment member 200 will be described with reference to FIG.

まず、図4(a)は、図3(a)に示す開口部210の長側方向の断面において、左側の第一係合突起220周辺を拡大して示している。なお、以下では、開口部210の一方側(図3(a)の左側)における、係合弾性板130と第一係合突起220との係合についての作用効果を説明しているが、当然に、開口部210の他方側(図3(a)の右側)における、係合弾性板130と第一係合突起220との係合についても、同じ作用効果が得られる。   First, FIG. 4A shows an enlarged view of the vicinity of the left first engagement protrusion 220 in the longitudinal section of the opening 210 shown in FIG. In the following, the operational effects of the engagement between the engagement elastic plate 130 and the first engagement protrusion 220 on one side of the opening 210 (the left side in FIG. 3A) will be described. In addition, the same effect can be obtained for the engagement between the engagement elastic plate 130 and the first engagement protrusion 220 on the other side of the opening 210 (the right side in FIG. 3A).

図4(a)は、留め具100を開口部210に挿入する前の状態を示している。この状態において、係合弾性板130の側端部134から第一係合突起220の先端222までの距離(言い換えると、係合弾性板130が弾性変形していない状態から、最も弾性変形する状態までの距離)をL5とする。   FIG. 4A shows a state before the fastener 100 is inserted into the opening 210. In this state, the distance from the side end portion 134 of the engagement elastic plate 130 to the tip 222 of the first engagement protrusion 220 (in other words, the state in which the engagement elastic plate 130 is not elastically deformed and is the most elastically deformed state). L5).

次に、図4(b)に示すように、留め具100が開口部210の上方から挿入されてゆくと、係合弾性板130の側面133が、第一係合突起220の傾斜面221に当接して、係合弾性板130は内側へ湾曲するように弾性変形する。   Next, as shown in FIG. 4B, when the fastener 100 is inserted from above the opening 210, the side surface 133 of the engagement elastic plate 130 becomes the inclined surface 221 of the first engagement protrusion 220. In contact with each other, the engagement elastic plate 130 is elastically deformed so as to bend inward.

さらに、留め具100が奥へ挿入されるのに従い、係合弾性板130の側端部134が、第一係合突起220の先端222を乗り越える。そして、係合弾性板130には外側へ向かう復元力が働いているので、係合弾性板130が外側へ向けて復帰して、図4(c)に示すように、先端222が傾斜した第一係合面131に当接して、上方及び側方にガタつきなく係合する状態となる。図に示すように、留め具100は被取付部材200に係合固定されているので、板材Tは、頭部120の裏面と被取付部材200との間に挟まれた状態で、被取付部材200に固定されることになる。   Further, as the fastener 100 is inserted deeper, the side end portion 134 of the engagement elastic plate 130 gets over the front end 222 of the first engagement protrusion 220. Since the restoring elastic force acting outward is acting on the engaging elastic plate 130, the engaging elastic plate 130 returns to the outside, and the tip 222 is inclined as shown in FIG. It will contact | abut to the one engagement surface 131, and will be in the state engaged without backlash | fluctuation upward and a side. As shown in the figure, since the fastener 100 is engaged and fixed to the attached member 200, the plate member T is sandwiched between the back surface of the head 120 and the attached member 200, and the attached member It will be fixed to 200.

ここで、係合箇所は傾斜した第一係合面131であるから、係合弾性板130が復帰する過程で、第一係合突起220の先端222に、第一係合面131のいずれかの位置が必ず係合する。これにより、例えば、第一係合突起220の寸法や、係合弾性板130の寸法に誤差があっても、先端222と第一係合面131との当接位置が、図4(c)に示す位置から、第一係合面131の傾斜した表面に沿って上方又は下方にずれるのみで、しっかりと係合する。つまり、係合箇所を傾斜した第一係合面131としたとこで、係合に関わる部材に寸法誤差があっても、確実に、上方及び側方にガタつきなく係合できるのである。   Here, since the engagement location is the inclined first engagement surface 131, any one of the first engagement surfaces 131 is placed on the tip 222 of the first engagement protrusion 220 in the process of returning the engagement elastic plate 130. The position of is always engaged. Thereby, for example, even if there is an error in the dimension of the first engagement protrusion 220 and the dimension of the engagement elastic plate 130, the contact position between the tip 222 and the first engagement surface 131 is as shown in FIG. From the position shown in FIG. 2, the first engagement surface 131 is firmly engaged only by shifting upward or downward along the inclined surface. In other words, the first engaging surface 131 is inclined at the engaging portion, so that even if there is a dimensional error in the member related to the engagement, it is possible to reliably engage the upper and the side without backlash.

また、第一係合突起220の先端222が、傾斜した第一係合面131に当接する態様であるから、仮に、図4(d)に示すように、留め具100が図面上左にずれても、先端222と第一係合面131とが当接した状態は維持される。したがって、留め具100が側方にずれたとしても、留め具100は開口部210に対して、側方及び上方にガタつきなく係合した状態を維持できるのである。   Further, since the tip 222 of the first engagement protrusion 220 is in contact with the inclined first engagement surface 131, the fastener 100 is temporarily shifted to the left in the drawing as shown in FIG. However, the state where the tip 222 and the first engagement surface 131 are in contact with each other is maintained. Therefore, even if the fastener 100 is displaced laterally, the fastener 100 can maintain a state in which the fastener 100 is engaged with the opening 210 in the lateral and upward directions without rattling.

また、図4(d)に示すように、留め具100が図面上左にずれると、係合弾性板130の先端側が、留め具100の中心方向(内側)へ持ち上げられるように変形する。すると、係合弾性板130には、留め具100を、ずらされた方向とは反対の右側へ押し戻そうとする復元力が働き、留め具の側方へのずれが修正される。   Further, as shown in FIG. 4D, when the fastener 100 is shifted to the left in the drawing, the distal end side of the engagement elastic plate 130 is deformed so as to be lifted in the center direction (inner side) of the fastener 100. Then, a restoring force that tries to push the fastener 100 back to the right side opposite to the shifted direction acts on the engagement elastic plate 130, and the lateral displacement of the fastener is corrected.

また、図4(c)及び(d)に示すように、留め具100が開口部210に挿入された状態では、係合弾性板130は内側に弾性変形しているので、第一係合突起220へ向かう復元力(付勢力)が常に働いている。そのため、係合弾性板130は、常に第一係合突起220と当接して係合しているので、留め具100は、開口部210に対して側方及び上方にガタつきなく係合する状態を維持できる。   Further, as shown in FIGS. 4C and 4D, when the fastener 100 is inserted into the opening 210, the engagement elastic plate 130 is elastically deformed inward, so that the first engagement protrusion The restoring force (biasing force) toward 220 is always working. Therefore, since the engagement elastic plate 130 is always in contact with and engaged with the first engagement protrusion 220, the fastener 100 is engaged with the opening 210 in the lateral and upward directions without rattling. Can be maintained.

一方、仮に、留め具100が図面上右にずれても、係合弾性板130には外側、つまり、第一係合突起220へ向かう復元力が働いているので、係合弾性板130は左側へ広がろうとする。そのため、先端222と第一係合面131の当接位置が、図4(c)に示す位置から、傾斜した第一係合面131の傾斜した表面に沿って上方に移動するだけで、係合弾性板130と第一係合突起220とは係合したままである。したがって、留め具100が側方にずれたとしても、留め具100は開口部210に対して、側方及び上方にガタつきなく係合した状態を維持できるのである。   On the other hand, even if the fastener 100 is displaced to the right in the drawing, since the restoring force toward the outer side, that is, the first engaging protrusion 220 is acting on the engaging elastic plate 130, the engaging elastic plate 130 is on the left side. Trying to spread. Therefore, the contact position between the tip 222 and the first engagement surface 131 simply moves upward along the inclined surface of the inclined first engagement surface 131 from the position shown in FIG. The composite elastic plate 130 and the first engagement protrusion 220 remain engaged. Therefore, even if the fastener 100 is displaced laterally, the fastener 100 can maintain a state in which the fastener 100 is engaged with the opening 210 in the lateral and upward directions without rattling.

このように、係合弾性板130と第一係合突起220との係合は、傾斜した第一係合面131によって実現されているため、側方及び上方にガタつきなく留め具100を係合し、さらに、その係合弾性板130の弾性によって、係合状態を維持することができるのである。   As described above, since the engagement between the engagement elastic plate 130 and the first engagement protrusion 220 is realized by the inclined first engagement surface 131, the fastener 100 can be engaged with the side and the upper side without backlash. In addition, the engagement state can be maintained by the elasticity of the engagement elastic plate 130.

ところで、図4(c)に示す状態で、留め具100が左側に大きくずらされると、係合弾性板130が、留め具100の中心方向(右側)へ持ち上げられるように大きく変形し(図4(d)の状態を参照)、又、留め具100が右側に大きくずらされると、自身の復元力で係合弾性板130は左側へ大きく広がろうとするため、第一係合突起220の先端222と第一係合面131との当接位置が、図4(c)に示す位置から、第一係合面131の傾斜した表面に沿って大きく上方に移動して、第一係合面131が先端222から外れてしまう虞がある。しかし、第一係合面131の上端には係合段部132が形成されているため、この係合段部132に、第一係合突起220の先端222が当接して引っ掛かる。よって、第一係合突起220と係合弾性板130との係合が外れないのである。   By the way, when the fastener 100 is largely shifted to the left in the state shown in FIG. 4C, the engagement elastic plate 130 is greatly deformed so as to be lifted in the center direction (right side) of the fastener 100 (FIG. 4). (Refer to the state of (d)) Further, when the fastener 100 is largely shifted to the right side, the engagement elastic plate 130 tends to expand to the left side by its own restoring force. The contact position between 222 and the first engagement surface 131 moves largely upward along the inclined surface of the first engagement surface 131 from the position shown in FIG. There is a possibility that 131 may come off the tip 222. However, since the engagement step 132 is formed at the upper end of the first engagement surface 131, the tip 222 of the first engagement protrusion 220 comes into contact with the engagement step 132 and is caught. Therefore, the engagement between the first engagement protrusion 220 and the engagement elastic plate 130 is not released.

また、図4(c)及び(d)に示す状態において、留め具100が強く上方へ引き抜かれそうになったとする。すると、留め具100の本体部110の先端が上方へ持ち上がり、係合弾性板130は左側へ広がろうとする。そのため、先端222が係合段部132にしっかりと引っかかり、係合弾性板130は、この先端222と本体部110の連結部115との間で、突っ張り棒のように作用し、湾曲状に撓むように変形することで、留め具100を押し戻そうとする復元力が働く。したがって、係合段部132を備えた係合弾性板130は、自身の復元力によって、上方の外力に対して強く対抗し、留め具100が外れるのを防止する。   Further, in the state shown in FIGS. 4C and 4D, it is assumed that the fastener 100 is about to be pulled out strongly. Then, the front end of the main body 110 of the fastener 100 is lifted upward, and the engagement elastic plate 130 tends to spread leftward. Therefore, the tip 222 is firmly caught by the engagement step 132, and the engagement elastic plate 130 acts like a tension rod between the tip 222 and the connecting portion 115 of the main body 110, and is bent in a curved shape. The deforming force that tries to push back the fastener 100 works by being deformed so as to be deformed. Therefore, the engagement elastic plate 130 provided with the engagement step portion 132 strongly opposes the upper external force by its restoring force, and prevents the fastener 100 from coming off.

ところで、仮に、図4(d)に示す状態から、さらに、留め具100が図面上左に無理にずらされた場合は、第一係合突起220の先端222が、係合段部132から外れてしまう虞がある。そこで、本体部110から一定の距離Xだけ離して設けられた移動防止部150によって、これを防止する。つまり、第一係合突起220の先端222が係合段部132から外れる前に、第一係合突起220と移動防止部150とが当接して、留め具100がそれ以上移動出来なくするのである。   Incidentally, if the fastener 100 is forcibly shifted to the left in the drawing from the state shown in FIG. 4D, the tip 222 of the first engagement protrusion 220 is disengaged from the engagement step portion 132. There is a risk that. Therefore, this is prevented by the movement preventing unit 150 provided at a certain distance X from the main body 110. That is, before the tip 222 of the first engagement protrusion 220 is disengaged from the engagement step portion 132, the first engagement protrusion 220 and the movement preventing portion 150 come into contact with each other, and the fastener 100 cannot move any further. is there.

なお、移動防止部150は、開口部210の内面と留め具100との距離を、第一係合突起220の先端222が係合段部132から外れない範囲で一定に保てればよい。そのため、移動防止部150は、第一係合突起220に当接する以外にも、開口部210のいずれかの一部に、当接し得るように変更してもよい。また、距離Xは、留め具100が開口部210内面に向けて移動した際に、第一係合突起220の先端222が係合段部132から外れないように設定されていれば、任意の長さに設定することができる。   In addition, the movement prevention part 150 should just maintain the distance of the inner surface of the opening part 210, and the fastener 100 in the range which the front-end | tip 222 of the 1st engagement protrusion 220 does not remove | deviate from the engagement step part 132. FIG. Therefore, the movement preventing unit 150 may be changed so as to be able to contact any part of the opening 210 in addition to contacting the first engagement protrusion 220. Further, the distance X is arbitrary as long as the tip end 222 of the first engagement protrusion 220 is not detached from the engagement step portion 132 when the fastener 100 moves toward the inner surface of the opening 210. Can be set to length.

また、図4(c)に示す、移動防止部150から移動防止部150が当接する第一係合突起220までの距離(言い換えると、留め具100の移動防止部150の移動可能距離)をL6とする。なお、この距離L6は、存在しないのが望ましいが、製品の寸法公差を考慮して、設ける必要がある。   4C, the distance from the movement prevention unit 150 to the first engagement protrusion 220 with which the movement prevention unit 150 abuts (in other words, the movable distance of the movement prevention unit 150 of the fastener 100) is L6. And The distance L6 preferably does not exist, but needs to be provided in consideration of the dimensional tolerance of the product.

なお、本実施例では、傾斜した第一係合面131は、表面が平坦なものであったが、これに限定されない。例えば、第一係合面は、表面が内側又は外側に湾曲したものや、凹凸があるものなど、表面形状は任意に変更することができる。   In the present embodiment, the inclined first engagement surface 131 has a flat surface, but is not limited thereto. For example, the surface shape of the first engagement surface can be arbitrarily changed, such as a surface whose surface is curved inward or outward, or a surface with irregularities.

ここまでは、係合弾性板130と第一係合突起220の係合について述べてきたが、次は、図5を参照して、係合弾性部140と第二係合突起230との係合について説明する。   Up to this point, the engagement between the engagement elastic plate 130 and the first engagement protrusion 220 has been described. Next, referring to FIG. 5, the engagement between the engagement elastic portion 140 and the second engagement protrusion 230 will be described. The case will be described.

図5(a)は、図3(b)に示す開口部210の短側方向の断面において、左側の第二係合突起230周辺を拡大して示している。なお、以下の図5では、開口部210の一方側(図3(b)の左側)における、係合弾性部140と第二係合突起230との係合についての作用効果を説明しているが、当然に、開口部210の他方側(図3(b)の右側)における、係合弾性部140と第二係合突起230との係合についても、同じ作用効果が得られる。   FIG. 5A shows an enlarged view of the vicinity of the second engagement protrusion 230 on the left side in the cross section in the short side direction of the opening 210 shown in FIG. In the following FIG. 5, the operational effect of the engagement between the engagement elastic portion 140 and the second engagement protrusion 230 on one side of the opening 210 (left side of FIG. 3B) is described. However, as a matter of course, the same effect can be obtained for the engagement between the engagement elastic portion 140 and the second engagement protrusion 230 on the other side of the opening 210 (the right side in FIG. 3B).

図5(a)に示すように、留め具100が開口部210の上方から挿入されてゆくと、係合弾性部140の側面143が、第二係合突起230の傾斜面231に当接して、係合弾性部140は内側へ湾曲するように弾性変形する。   As shown in FIG. 5A, when the fastener 100 is inserted from above the opening 210, the side surface 143 of the engagement elastic portion 140 comes into contact with the inclined surface 231 of the second engagement protrusion 230. The engaging elastic part 140 is elastically deformed so as to be bent inward.

さらに、留め具100が奥へ挿入されるのに従い、係合弾性部140の側端部144が、第二係合突起230の先端232を乗り越える。すると、係合弾性部140は自身の復元力によって、図5(b)に示すように、変形前の状態へと復帰し、係合弾性部140と第二係合突起230とが係合する。そして、板材Tは、頭部120の裏面と被取付部材200との間に挟まれた状態で固定されることになる。   Further, as the fastener 100 is inserted deeper, the side end portion 144 of the engagement elastic portion 140 gets over the front end 232 of the second engagement protrusion 230. Then, as shown in FIG. 5B, the engagement elastic portion 140 returns to the state before the deformation by its own restoring force, and the engagement elastic portion 140 and the second engagement protrusion 230 are engaged. . And the board | plate material T will be fixed in the state pinched | interposed between the back surface of the head 120, and the to-be-attached member 200. FIG.

なお、留め具100が上方へ引き抜かれそうになっても、第二係合突起230の係合面233と係合弾性部140の第二係合面141とが面と面で当接する。そのため、第二係合突起230と係合弾性部140は非常に強く係合するので、留め具100が外れることはないのである。   Even when the fastener 100 is about to be pulled upward, the engagement surface 233 of the second engagement protrusion 230 and the second engagement surface 141 of the engagement elastic portion 140 are in contact with each other. Therefore, the second engagement protrusion 230 and the engagement elastic part 140 are engaged very strongly, so that the fastener 100 does not come off.

ところで、図5(b)に示すように、留め具100の頭部120の裏面が板材T及び第二係合突起230に当接して、奥までしっかり挿入された状態で、第二係合突起230と係合弾性部140との間には、僅かな隙間Sが出来ている。これは、図5(a)から図5(b)にかけて示すように、第二係合面141を先端に備えた係合弾性部140が、内側へ変形した後、再び第二係合突起230の係合面233に相対するように、復帰するのをスムーズに実現するためである。仮に、この隙間Sがなければ、第二係合面141が係合面233に引っ掛かり、係合弾性部140がスムーズに復帰できない虞がある。なお、第二係合面141と係合面233とは、面接触できるように、互いに平行な平坦面(言い換えるならば、互いに一致するように対応した形状)であったが、後述する図7(b)及び(c)に示すように、第二係合面141又は係合面233のいずれか一方を傾斜させれば、この隙間Sが無くても、係合弾性部140はスムーズに復帰できる。   By the way, as shown in FIG.5 (b), in the state which the back surface of the head 120 of the fastener 100 contact | abutted to the board | plate material T and the 2nd engagement protrusion 230, and was inserted to the back firmly, the 2nd engagement protrusion A slight gap S is formed between 230 and the engagement elastic portion 140. As shown in FIGS. 5 (a) to 5 (b), the second engagement protrusion 230 is again formed after the engagement elastic portion 140 having the second engagement surface 141 at the tip is deformed inward. This is because the return can be smoothly realized so as to face the engagement surface 233. If there is no gap S, the second engagement surface 141 may be caught on the engagement surface 233, and the engagement elastic part 140 may not be able to return smoothly. The second engagement surface 141 and the engagement surface 233 are flat surfaces parallel to each other (in other words, shapes corresponding to each other so that they can be brought into contact with each other). As shown in (b) and (c), if either one of the second engagement surface 141 or the engagement surface 233 is inclined, the engagement elastic portion 140 returns smoothly even without this gap S. it can.

また、この係合弾性部140と第二係合突起230の係合は、面と面との係合であることや、係合弾性部140は係合弾性板130に比べて全長が短いため、変形量が少なく剛性が高いことから、図4で説明した係合弾性板130と第一係合突起220との係合よりも強い。そして、この面と面との係合をスムーズに実現するには、隙間Sを設けるのが好ましいが、その反面、この隙間Sによる留め具100の上方へのガタつきが発生する。そこで、この係合弾性部140とは別に、傾斜した第一係合面131を設けた係合弾性板130による係合を利用して、留め具100の上方へのガタつきを効果的に抑制したのである。   Further, the engagement between the engagement elastic portion 140 and the second engagement protrusion 230 is the engagement between the surfaces, and the engagement elastic portion 140 has a shorter overall length than the engagement elastic plate 130. Since the amount of deformation is small and the rigidity is high, the engagement is stronger than the engagement between the engagement elastic plate 130 and the first engagement protrusion 220 described with reference to FIG. In order to smoothly realize the engagement between the surfaces, it is preferable to provide the gap S, but on the other hand, rattling of the fastener 100 due to the gap S occurs. Therefore, apart from the engagement elastic portion 140, the engagement by the engagement elastic plate 130 provided with the inclined first engagement surface 131 is used to effectively suppress the backlash of the fastener 100 upward. It was.

このように、留め具100は、係合弾性部140と第二係合突起230との係合に加えて、係合弾性板130と第一係合突起220との係合を同時に実現することで、従来のように、ピンを溶融させて固着させなくても、留め具100の強力な係合のみで、十分に板材Tを被取付部材200に固定できる。さらに、係合弾性板130によって、側方及び上方にガタつきなく係合した状態を維持できる。   As described above, the fastener 100 simultaneously realizes the engagement between the engagement elastic plate 130 and the first engagement protrusion 220 in addition to the engagement between the engagement elastic portion 140 and the second engagement protrusion 230. Thus, the plate material T can be sufficiently fixed to the mounted member 200 only by the strong engagement of the fastener 100 without melting the pins and fixing them as in the prior art. Furthermore, the engagement elastic plate 130 can maintain a state where the engagement elastic plate 130 is engaged with the side and the upper side without backlash.

また、留め具100が上方へ引っ張られても、留め具100が外れることはないが、もし板材Tを交換するために、留め具100を取り外す必要があるときは、留め具100の係合弾性板130及び係合弾性部140を破損させれば、留め具100のみ取り外すことができる。つまり、従来のように、溶着によって一体化した板材Tと被取付部材200を破壊する必要がないため、本願発明では、留め具100のみを破壊して取り外し、新たな留め具100を用いて、被取付部材200に交換後の板材Tを再度取付けることができる。上記では、留め具100を破損させて取り外していたが、留め具100を破損させないで取り外す方法としては、係合弾性板130及び係合弾性部140を内側に撓ませて、係合を解除するために、第一係合突起220と係合弾性板130の間、及び第二係合突起230と係合弾性部140の間に、略四角筒状の治具を挿入して、係合弾性板130及び係合弾性部140を、留め具100の中心方向へ寄せる方法を採用してもよい。   Further, even if the fastener 100 is pulled upward, the fastener 100 does not come off, but if it is necessary to remove the fastener 100 in order to replace the plate material T, the engagement elasticity of the fastener 100 If the plate 130 and the engagement elastic part 140 are damaged, only the fastener 100 can be removed. That is, unlike the conventional case, there is no need to destroy the plate member T and the attached member 200 integrated by welding, so in the present invention, only the fastener 100 is destroyed and removed, and the new fastener 100 is used. The plate material T after replacement can be attached to the attached member 200 again. In the above description, the fastener 100 is damaged and removed. However, as a method of removing the fastener 100 without damaging it, the engagement elastic plate 130 and the engagement elastic portion 140 are bent inward to release the engagement. Therefore, a substantially square cylindrical jig is inserted between the first engagement protrusion 220 and the engagement elastic plate 130, and between the second engagement protrusion 230 and the engagement elastic portion 140, thereby A method of bringing the plate 130 and the engaging elastic portion 140 toward the center of the fastener 100 may be employed.

なお、本実施例では、留め具100の略直方体形状の本体部110の各側面に、具体的には、図1に示すように、相対する側面の左側面111と右側面112に、それぞれ係合弾性板130を設け、さらに、相対する側面の前側面113と後側面114に、それぞれ係合弾性部140を設けている。このように、相対する側面に、各係合部材を設けることで、本体部110の挿入方向に関わらず、本体部110を開口部210に挿入できる(例えば、前側面113と後側面114のどちらかを前側に持ってきて、挿入しなければならないという不便がない。)。また、係合弾性板130を本体部110の両端に設けたことで、留め具100の左右のずれに、バランスよく安定して対応できる。   In the present embodiment, each side of the substantially rectangular parallelepiped main body 110 of the fastener 100, specifically, the left side 111 and the right side 112 of the opposite side as shown in FIG. The composite elastic plate 130 is provided, and the engaging elastic portions 140 are provided on the front side surface 113 and the rear side surface 114 of the opposite side surfaces, respectively. In this manner, by providing each engaging member on the opposite side surface, the main body portion 110 can be inserted into the opening 210 regardless of the insertion direction of the main body portion 110 (for example, which of the front side surface 113 and the rear side surface 114 is There is no inconvenience that you have to bring it to the front and insert it.) Further, by providing the engagement elastic plates 130 at both ends of the main body 110, it is possible to cope with the right and left displacement of the fastener 100 stably in a balanced manner.

また、留め具100の本体部110は略直方体形状であるが、これに限定されず、円柱形状やその他の形状であってもよい。例えば、円柱形状の本体部110であっても、その側面の一部(一方の側面)に係合弾性板130を設け、その他の部分(他方の側面)に係合弾性部140を設けることができる。   Moreover, although the main-body part 110 of the fastener 100 is a substantially rectangular parallelepiped shape, it is not limited to this, A cylindrical shape and another shape may be sufficient. For example, even in the cylindrical main body 110, the engagement elastic plate 130 may be provided on a part of the side surface (one side surface), and the engagement elastic part 140 may be provided on the other portion (the other side surface). it can.

また、本実施例では、第二係合面141は、表面が平坦なものであったが、これに限定されない。例えば、第二係合面は、表面が内側又は外側に湾曲したものや、凹凸があるものなど、表面形状は任意に変更することができる。   Moreover, in the present Example, although the surface of the 2nd engagement surface 141 was flat, it is not limited to this. For example, the surface shape of the second engagement surface can be arbitrarily changed, such as a surface whose surface is curved inward or outward, or a surface with irregularities.

では、次に、本願発明の変形例について、図6(a)及び(b)を参照して説明する。なお、図6(a)及び(b)で示す変形例では、留め具100及び被取付部材200の構造に変更はなく、留め具100の被取付部材200に対する位置関係が異なる。具体的には、板材Uは板材Tよりも高さが高いため、留め具100を開口部210に挿入すると、図6(a)に示すように、頭部120と第一係合突起220の間に空間Rが出来る。また、板材Uは、留め具100が開口部210へ向けて押し込められる力によって、頭部120に接する周辺部分が、変形可能な程度の弾性を有するとする。   Next, a modification of the present invention will be described with reference to FIGS. 6 (a) and 6 (b). In the modification shown in FIGS. 6A and 6B, the structures of the fastener 100 and the attached member 200 are not changed, and the positional relationship of the fastener 100 with respect to the attached member 200 is different. Specifically, since the plate member U is higher in height than the plate member T, when the fastener 100 is inserted into the opening 210, the head 120 and the first engagement protrusion 220 are inserted as shown in FIG. A space R is created between them. Further, it is assumed that the plate member U has elasticity such that the peripheral portion in contact with the head 120 can be deformed by the force with which the fastener 100 is pushed toward the opening 210.

まず、使用者が開口部210に留め具100を軽く挿入すると、図6(a)に示すように、頭部120裏面が板材Uと当接して、留め具100がそれ以上進まなくなる(この状態を、第一当接状態と呼ぶ。)。さらに、使用者は、留め具100を開口部210に強く押し込むと(図6(b)の実線矢印を参照)、図6(b)に示すように、空間Rが無くなるまで、つまり、頭部120の裏面と第一係合突起220の上端が当接するまで、板材Uは下方へ凹む。また、頭部120の裏面が第一係合突起220の上端に当接しているので、留め具100は、それ以上押し込まれない(この状態を、第二当接状態と呼ぶ。)。   First, when the user inserts the fastener 100 lightly into the opening 210, as shown in FIG. 6A, the back surface of the head 120 comes into contact with the plate material U, and the fastener 100 does not advance any further (this state). Is referred to as a first contact state). Further, when the user strongly pushes the fastener 100 into the opening 210 (see the solid line arrow in FIG. 6B), as shown in FIG. 6B, until the space R disappears, that is, the head The plate material U is recessed downward until the back surface of 120 and the upper end of the first engagement protrusion 220 abut. Moreover, since the back surface of the head 120 is in contact with the upper end of the first engagement protrusion 220, the fastener 100 is not pushed any further (this state is referred to as a second contact state).

なお、この第二当接状態においては、先端222が係合段部132に押し当てられて、係合弾性板130が内側へ弾性変形している。   In the second contact state, the tip 222 is pressed against the engagement step 132, and the engagement elastic plate 130 is elastically deformed inward.

次に、使用者が留め具100を押し込めるのを止めると、板材Uは元の図6(a)に示す第一当接状態に復帰し、それに伴い、留め具100は上方へ押し上げられる(図6(b)の破線矢印を参照)。その際、係合弾性板130は、留め具100と一緒に上方へ移動すると共に、自身の復元力で、第一係合突起220に向けて広がろうとする。   Next, when the user stops pushing the fastener 100, the plate material U returns to the first contact state shown in FIG. 6A, and accordingly, the fastener 100 is pushed upward (FIG. 6). (See broken line arrows in 6 (b)). At that time, the engagement elastic plate 130 moves upward together with the fastener 100 and tends to spread toward the first engagement protrusion 220 by its own restoring force.

そのため、第二当接状態(図6(b)参照)から第一当接状態(図6(a)参照)に復帰する過程で、第一係合突起220の先端222と、第一係合面131とが確実に係合することになる。   Therefore, in the process of returning from the second contact state (see FIG. 6B) to the first contact state (see FIG. 6A), the tip 222 of the first engagement protrusion 220 and the first engagement The surface 131 is securely engaged.

ここで、使用者の視点に立つと、先に、留め具100が押し込みにくくなる第一当接段階に直面し、その段階からさらに強く押し込んで、それ以上完全に押し込めない第二当接段階に直面するというように、各段階を経験することで、確実に留め具100を開口部210に押し込んで係合させたという感覚を得ることでき、係合作業の確実性を高めることができる。   Here, from the user's point of view, first, the fastener 100 faces the first contact stage where the push-in 100 becomes difficult to push in, and further pushes further from that stage to the second contact stage where it cannot be pushed in any further. As faced, by experiencing each step, it is possible to obtain a feeling that the fastener 100 is surely pushed into the opening 210 and engaged therewith, and the reliability of the engagement work can be improved.

なお、上記作用は、空間Rが形成され、さらに、板材Uが弾性変形することで実現しているがこれに限定されず、たとえば、図6(c)に示す他の変形例のように、留め具100´の頭部120´の裏面であって、板材と当接する箇所に、突出部分121´を設けることで実現してもよい。   In addition, although the said effect | action is implement | achieved because space R is formed and also the board | plate material U elastically deforms, it is not limited to this, For example, like the other modification shown in FIG.6 (c), You may implement | achieve by providing protrusion part 121 'in the location which is a back surface of head 120' of fastener 100 ', and contact | abuts with a board | plate material.

具体的には、図6(c)に示すように、留め具100´が開口部210に挿入された状態で、突出部分121´が、第一係合突起220の上端と同一平面の板材Tに当接している。そのため、頭部120´と第一係合突起220の上端との間には、空間Rが形成される。そして、使用者が留め具100´を強く押すと、板材Tが凹むように弾性変形して、空間Rが無くなるまで、留め具100´が開口部210に押し込まれる。その後、板材Tが元の状態へ復帰し、留め具100が上方へ押し上げられる。その際、図6(a)から図6(b)にかけて上述したのと同一の作用効果が得られる。また、板材Tが弾性変形しない場合は、留め具100´が強く押された際に、突出部分121´周辺の頭部120´が反り返るように弾性変形できるようにしてもよい。   Specifically, as shown in FIG. 6C, the protruding portion 121 ′ is in the same plane as the upper end of the first engagement protrusion 220 with the fastener 100 ′ inserted into the opening 210. Abut. Therefore, a space R is formed between the head 120 ′ and the upper end of the first engagement protrusion 220. When the user strongly presses the fastener 100 ′, the fastener 100 ′ is pushed into the opening 210 until the plate material T is elastically deformed so as to be recessed and the space R disappears. Thereafter, the plate material T returns to the original state, and the fastener 100 is pushed upward. At that time, the same effect as described above from FIG. 6A to FIG. 6B can be obtained. Further, when the plate material T is not elastically deformed, the head portion 120 ′ around the protruding portion 121 ′ may be elastically deformed so that it is warped when the fastener 100 ′ is strongly pressed.

なお、留め具が開口部に挿入されて係合された状態において、留め具を押し込むことができる空間を形成し、留め具が押し込まれた後に、元の係合位置に復帰できる構成であれば、上述した以外の他の構成を採用してもよい。   In addition, in a state where the fastener is inserted into the opening and engaged, a space in which the fastener can be pushed in is formed, and after the fastener is pushed in, the structure can be returned to the original engagement position. Other configurations than those described above may be employed.

では、次に、本願発明の他の変形例について、図7を参照して説明する。なお、図7(a)及び(b)で示す変形例では、被取付部材200aの第二係合突起230a及び被取付部材200bの第二係合突起230bの形状が、図5に示す被取付部材200の第二係合突起230の形状と異なるだけで、他の構成は被取付部材200と同一である。また、図7(c)及び(d)で示す変形例では、留め具100aの係合弾性部140a及び留め具100bの係合弾性部140bの形状が、図5に示す留め具100の係合弾性部140の形状と異なるだけで、他の構成は留め具100と同一である。   Next, another modification of the present invention will be described with reference to FIG. In the modification shown in FIGS. 7A and 7B, the shapes of the second engagement protrusions 230a of the attached member 200a and the second engagement protrusions 230b of the attached member 200b are as shown in FIG. Other configurations are the same as those of the mounted member 200 except for the shape of the second engagement protrusion 230 of the member 200. 7C and 7D, the shapes of the engagement elastic portion 140a of the fastener 100a and the engagement elastic portion 140b of the fastener 100b are the same as the engagement of the fastener 100 shown in FIG. Other configurations are the same as those of the fastener 100 except for the shape of the elastic portion 140.

まず、図7(a)に示す第二係合突起230aでは、開口部210a内側へ向けて下方へ傾斜する係合面233aが形成されている。また、図7(b)に示す第二係合突起230bでは、開口部210b外側へ向けて下方へ傾斜する係合面233bが形成されている。そして、第二係合突起230a及び第二係合突起230bのいずれも、係合弾性部140の第二係合面141と線接触することになる。   First, in the second engagement protrusion 230a shown in FIG. 7A, an engagement surface 233a that is inclined downward toward the inside of the opening 210a is formed. Further, in the second engagement protrusion 230b shown in FIG. 7B, an engagement surface 233b that is inclined downward toward the outside of the opening 210b is formed. Then, both the second engagement protrusion 230a and the second engagement protrusion 230b are in line contact with the second engagement surface 141 of the engagement elastic part 140.

次に、図7(c)に示す係合弾性部140aでは、本体部110aへ向けて下方へ傾斜する第一係合面141aが形成されている。また、図7(d)に示す係合弾性部140bでは、本体部110bの外側へ向けて下方へ傾斜する第一係合面141bが形成されている。そして、第一係合面141a及び第一係合面141bのいずれも、第二係合突起230と線接触することになる。   Next, in the engagement elastic part 140a shown in FIG.7 (c), the 1st engagement surface 141a which inclines below toward the main-body part 110a is formed. Moreover, in the engagement elastic part 140b shown in FIG.7 (d), the 1st engagement surface 141b which inclines below toward the outer side of the main-body part 110b is formed. Then, both the first engagement surface 141a and the first engagement surface 141b are in line contact with the second engagement protrusion 230.

このように、第二係合突起の係合面と、係合弾性部の第二係合面とを異なる形状とすることで、互いに面接触ではなく、線接触することになる。これは、例えば、留め具に要求される固定力が、面接触より係合力が弱い線接触で十分な場合に、適宜採用することができる。   Thus, by making the engagement surface of the second engagement protrusion different from the second engagement surface of the engagement elastic portion, they are in line contact with each other instead of surface contact. This can be adopted as appropriate when, for example, the fixing force required for the fastener is sufficient for the line contact whose engagement force is weaker than the surface contact.

なお、図7(a)又は(b)に示す第二係合突起のいずれかと、図7(c)又は(d)に示す係合弾性部のいずれかは、それぞれ互いに組み合わせて実施してもよい。例えば、図7(b)に示す第二係合突起230bと、図7(d)に示す係合弾性部140bとの組み合わせにおいては、係合面233bと第一係合面141bのそれぞれの表面が、互いに平行な平坦面となっているので、面接触することになる。このように、係合面233bと第一係合面141bの形状を、互いに一致するように対応した形状とすることで、面接触させることができる。   It should be noted that either of the second engagement protrusions shown in FIG. 7 (a) or (b) and any of the engagement elastic portions shown in FIG. 7 (c) or (d) may be implemented in combination with each other. Good. For example, in the combination of the second engagement protrusion 230b shown in FIG. 7B and the engagement elastic portion 140b shown in FIG. 7D, the respective surfaces of the engagement surface 233b and the first engagement surface 141b. However, since they are flat surfaces parallel to each other, they come into surface contact. In this way, the contact surfaces can be brought into surface contact by making the shapes of the engagement surface 233b and the first engagement surface 141b corresponding to each other.

なお、本願発明の留め具は、上記の実施例に限定されず、例えば、コンテナ以外の構造物に板材等を固定する際に利用することができ、さらに、特許請求の範囲に記載された範囲、実施形態の範囲で、種々の変形例、組み合わせが可能であり、これらの変形例、組み合わせもその権利範囲に含むものである。
