Description

本発明は、固定具に関する。   The present invention relates to a fixture.

例えば、自動車の製造にあたって、各種部品(特に、AMフィルターや、AM/FMアンプ等の電装品)は、ネジによるネジ止めによって車体に固定される。通常、作業者は、このようなネジ止めの作業を、一方の手で部品を車体の所定位置に固定し、他方の手でドライバー等の工具によりネジを押し込みながら締め付けることにより行う。しかしながら、このような作業方法では、両手が塞がっているため手でネジを支えることが困難であり、その結果、作業途中でネジが抜け落ちてしまい、作業効率が悪化するという問題が生じる。   For example, when manufacturing automobiles, various parts (particularly, electrical components such as AM filters and AM / FM amplifiers) are fixed to the vehicle body by screws. Usually, an operator performs such screwing work by fixing a part at a predetermined position of the vehicle body with one hand and tightening the screw with a tool such as a screwdriver with the other hand. However, in such a working method, it is difficult to support the screw with both hands because the hands are closed, and as a result, the screw falls off during the work, resulting in a problem that work efficiency is deteriorated.

特許文献1には、このような問題を解消するための固定クリップが開示されている。特許文献1の固定クリップは、例えば、自動車のボディの天井にハンドグリップを固定するのに用いられる。この固定クリップは、U字状に形成された部分とその基端に設けられ前記U字状の部分よりも拡径したストリップとを有するアンカー固定部分と、アンカー固定部分と別体として形成され、アンカー固定部の内側に設けられたプレートとを有している。   Patent Document 1 discloses a fixing clip for solving such a problem. The fixing clip of Patent Document 1 is used, for example, to fix a hand grip to the ceiling of the body of an automobile. This fixing clip is formed separately from an anchor fixing portion having a U-shaped portion and a strip provided at the base end thereof and having a diameter larger than that of the U-shaped portion, and the anchor fixing portion. And a plate provided inside the anchor fixing portion.

このような固定クリップは、次のようにしてハンドグリップをボディに固定する。まず、ボディの天井に形成された穴にアンカー固定部分のU字状の部分を天井にストリップが当接するまで挿入する。次いで、ハンドグリップの保持プレートをストリップに埋設する。ストリップには、固定ネジを挿通する穴が形成されており、この穴を介して固定ネジが挿通され、さらにこの固定ネジをプレートに螺合する。次いで、固定ネジを回転させてプレートを保持プレートに接近させる。プレートは、保持プレート側へ変位する際中に、アンカー固定部分に設けられた拡開フラップを外側へ押し広げ、押し広げられた拡開フラップを天井の穴付近に圧接させることにより、保持プレートを天井に固定する。   Such a fixing clip fixes the hand grip to the body as follows. First, the U-shaped portion of the anchor fixing portion is inserted into the hole formed in the ceiling of the body until the strip comes into contact with the ceiling. Next, the holding plate of the hand grip is embedded in the strip. The strip is formed with a hole through which the fixing screw is inserted. The fixing screw is inserted through the hole, and the fixing screw is screwed into the plate. Then, the fixing screw is rotated to bring the plate closer to the holding plate. During the displacement of the plate to the holding plate side, the expansion flap provided on the anchor fixing part is pushed outward, and the spread expansion flap is pressed near the hole in the ceiling, so that the holding plate is Secure to the ceiling.

このような固定クリップによれば、固定したい部材を固定したい場所(部材)に簡単に固定することができる。しかしながら、特許文献1の固定クリップは、固定ネジと固定クリップの間に固定したい部材を介在させるため、組立途中で固定ネジを固定クリップに取り付ける必要がある。そのため、固定ネジをうまく取り付けることができなかったり、落してしまったりするおそれがあり、組立をスムーズに行うことができないという問題がある。また、構成が複雑となるという問題もある。   According to such a fixing clip, a member to be fixed can be easily fixed to a place (member) to be fixed. However, since the fixing clip of Patent Document 1 interposes a member to be fixed between the fixing screw and the fixing clip, it is necessary to attach the fixing screw to the fixing clip during assembly. Therefore, there is a possibility that the fixing screw cannot be attached well or dropped, and there is a problem that assembly cannot be performed smoothly. There is also a problem that the configuration becomes complicated.

Of the leg portions 31 and 32, the leg portion 31 is inserted into the notch 22 formed in the fixing member 2, and the leg portion 32 is inserted into the notch 23. These leg portions 31 and 32 are slidable with respect to the fixing member 2 in the notches 22 and 23.

図3に示すように、脚部31の幅(X軸方向の長さ)W1は、切り欠き22の幅(X軸方向の長さ)W2よりも若干短く設定されている。同様に、脚部32の幅W3は、切り欠き23の幅W4よりも若干短く設定されている。また、一対の脚部31、32の離間距離D1は、一対の切り欠き22、23の離間距離D2よりも大きく、固定部材2の幅(Y軸方向の長さ)D3よりも小さい。脚部31、32をこのように設計することにより、連結部材3の切り欠き22、23からの脱落が防止されるとともに、脚部31、32が固定部材2に過剰に当接するのが防止され、当該当接による摺動抵抗をより少なく抑えることができる。そのため、固定部材2に対して脚部31、32(すなわち、連結部材3)をスムーズにスライドさせることができる。   As shown in FIG. 3, the width (length in the X-axis direction) W1 of the leg portion 31 is set slightly shorter than the width (length in the X-axis direction) W2 of the notch 22. Similarly, the width W3 of the leg portion 32 is set slightly shorter than the width W4 of the notch 23. Further, the separation distance D1 between the pair of leg portions 31 and 32 is larger than the separation distance D2 between the pair of notches 22 and 23 and smaller than the width (length in the Y-axis direction) D3 of the fixing member 2. By designing the leg portions 31 and 32 in this way, the connecting member 3 is prevented from falling off from the notches 22 and 23, and the leg portions 31 and 32 are prevented from excessively contacting the fixing member 2. Thus, the sliding resistance due to the contact can be reduced. Therefore, the leg portions 31 and 32 (that is, the connecting member 3) can be smoothly slid with respect to the fixing member 2.

また、一対の脚部31、32の離間距離D1は、貫通孔210の長さ(Y軸方向の長さ)よりも小さく設定されている。   Further, the separation distance D1 between the pair of leg portions 31 and 32 is set to be smaller than the length of the through hole 210 (the length in the Y-axis direction).

図2に示すように、連結部33は、各脚部31、32の下端部(連結部材3の挿入方向の先端部)同士を連結するように設けられている。連結部33は、連結部材3の先端(貫通孔210への挿入方向の先端)に位置する螺合部331と、螺合部331と脚部31とを連結する傾斜部332と、螺合部331と脚部32とを連結する傾斜部333とで構成されている。   As shown in FIG. 2, the connection part 33 is provided so that the lower end part (tip part of the insertion direction of the connection member 3) of each leg part 31 and 32 may be connected. The connecting portion 33 includes a screwing portion 331 located at the tip of the connecting member 3 (tip in the insertion direction into the through hole 210), an inclined portion 332 that connects the screwing portion 331 and the leg portion 31, and a screwing portion. It is comprised by the inclination part 333 which connects 331 and the leg part 32. FIG.

螺合部331は、薄い板状をなし、その主面(厚さ方向に対向する一対の面)がXY平面と平行に配置されている。また、螺合部331のY軸方向の長さは、脚部31、32の離間距離D1よりも小さい。また、XY平面視において、螺合部331は、一対の脚部31、32の間に位置している。   The screwing portion 331 has a thin plate shape, and its main surface (a pair of surfaces facing in the thickness direction) is arranged in parallel with the XY plane. Further, the length of the threaded portion 331 in the Y-axis direction is smaller than the separation distance D1 between the leg portions 31 and 32. Further, in the XY plan view, the screwing portion 331 is located between the pair of leg portions 31 and 32.

螺合部331の平面視形状は、部材200に形成された貫通孔210を通過(貫通)することができれば特に限定されず、本実施形態では、長辺および短辺がそれぞれ貫通孔210の長辺および短辺よりも短く、Y軸方向に延在する略長方形をなしている。   The planar view shape of the screwing portion 331 is not particularly limited as long as it can pass (penetrate) through the through-hole 210 formed in the member 200. In this embodiment, the long side and the short side are the length of the through-hole 210, respectively. It is shorter than the side and the short side and has a substantially rectangular shape extending in the Y-axis direction.

また、図2に示すように、螺合部331の中央部には、例えばバーリング加工によって、他の部分より肉厚なネジ穴331aが形成されている。ネジ穴331aの内壁には、ネジ4と螺合するネジ溝が形成されている。   As shown in FIG. 2, a screw hole 331a thicker than other portions is formed in the central portion of the screwing portion 331 by, for example, burring. On the inner wall of the screw hole 331a, a screw groove to be screwed with the screw 4 is formed.

ネジ4は、ネジ穴331aと螺合しており、ネジ4を一方に回転させると螺合部331が固定部材2に接近するように連結部材3が変位し、他方に回転させると螺合部331が固定部材2から離間するように連結部材3が変位する。   The screw 4 is screwed into the screw hole 331a. When the screw 4 is rotated in one direction, the connecting member 3 is displaced so that the screwed portion 331 approaches the fixing member 2, and when the screw 4 is rotated in the other direction, the screwed portion. The connecting member 3 is displaced so that 331 is separated from the fixing member 2.

傾斜部332は、薄い板状をなし、その主面(厚さ方向に対向する一対の面)がXY平面およびXZ平面に対してそれぞれ傾斜するように配置されている。同様に、傾斜部333も、薄い板状をなし、その主面がXY平面およびXZ平面に対して傾斜するように配置されている。   The inclined portion 332 has a thin plate shape, and is arranged such that its main surface (a pair of surfaces opposed in the thickness direction) is inclined with respect to the XY plane and the XZ plane, respectively. Similarly, the inclined portion 333 also has a thin plate shape, and is arranged so that its main surface is inclined with respect to the XY plane and the XZ plane.

一対の傾斜部332、333の離間距離D4は、螺合部331側から脚部31、32側に向けて漸減している。すなわち、連結部33は、連結部材3の先端側を先細りさせるテーパ部を構成している。このような形状の連結部33を備えることにより、連結部材3の先端部が貫通孔210に案内され易くなり、連結部材3を貫通孔210にスムーズに挿入することができる。   The distance D4 between the pair of inclined portions 332 and 333 gradually decreases from the screwing portion 331 side toward the leg portions 31 and 32 side. That is, the connecting portion 33 constitutes a tapered portion that tapers the distal end side of the connecting member 3. By providing the connecting portion 33 having such a shape, the tip end portion of the connecting member 3 is easily guided to the through hole 210, and the connecting member 3 can be smoothly inserted into the through hole 210.

図4に示すように、傾斜部332は、その幅(X軸方向の長さ)W5が螺合部331側から脚部31側に向けて漸増する略台形形状をなしている。さらに、傾斜部332の上端(脚部31側の端)の幅は、脚部31の幅よりも大きい。そして、傾斜部332は、上端の両縁部を除く中央部にて脚部31と連結している。なお、傾斜部333の形状は、傾斜部332の形状と同様であるため、その説明を省略する。   As shown in FIG. 4, the inclined portion 332 has a substantially trapezoidal shape in which the width (length in the X-axis direction) W5 gradually increases from the screwing portion 331 side toward the leg portion 31 side. Furthermore, the width of the upper end of the inclined portion 332 (the end on the leg portion 31 side) is larger than the width of the leg portion 31. And the inclination part 332 is connected with the leg part 31 in the center part except the both edge parts of an upper end. In addition, since the shape of the inclined part 333 is the same as the shape of the inclined part 332, the description is abbreviate | omitted.

図4に示すように、傾斜部332の上端部、すなわち連結部33の一端部には、一対のツメ部34、35が設けられている。一対のツメ部34、35は、XZ平面視にて、脚部31に対して互いに反対側に位置している。   As shown in FIG. 4, a pair of claw portions 34 and 35 are provided at the upper end portion of the inclined portion 332, that is, at one end portion of the connecting portion 33. The pair of claw portions 34 and 35 are located on the opposite sides of the leg portion 31 in the XZ plan view.

これらツメ部34、35は、それぞれ、連結部材3の外側へかつ固定部材2側に向けて突出している(すなわち、図2中左斜め上方向に向けて突出している)。また、本実施形態では、各ツメ部34、35は、傾斜部332と同一平面上に形成されている。また、図4に示すように、各ツメ部34、35は、その先端側へ向けて幅が漸減する略三角形をなしており、3つの角のうち、先端部を構成する角がY軸方向において最も外側に位置している。   Each of the claw portions 34 and 35 protrudes toward the outer side of the connecting member 3 and toward the fixing member 2 (that is, protrudes obliquely upward to the left in FIG. 2). In the present embodiment, the claw portions 34 and 35 are formed on the same plane as the inclined portion 332. As shown in FIG. 4, each claw portion 34, 35 has a substantially triangular shape whose width gradually decreases toward the tip side, and among the three corners, the corner constituting the tip portion is in the Y-axis direction. At the outermost position.

図4に示すように、ツメ部34、35の先端同士の離間距離D5は、固定部材2に形成された切り欠き22の幅W2よりも大きい。このように設計すれば、連結部材3を螺合部331が固定部材2に接近するように変位させると、その途中でツメ部34、35が固定部材2の下面に当接し、連結部材3のそれ以上の変位が阻止される。これにより、連結部材3の固定部材2側への過剰な変位を防止でき、固定具1の操作性が向上する。また、離間距離D5は、貫通孔210のX軸方向の長さと等しいか短いのが好ましい。これにより、連結部材3を貫通孔210にスムーズに挿入することができる。なお、傾斜部333の上端部、すなわち連結部33の他端部にも一対のツメ部36、37が設けられているが、一対のツメ部36、37は、一対のツメ部34、35と同様の構成であるため、その説明を省略する。   As shown in FIG. 4, the distance D <b> 5 between the tips of the claw portions 34 and 35 is larger than the width W <b> 2 of the notch 22 formed in the fixing member 2. With this design, when the connecting member 3 is displaced so that the screwing portion 331 approaches the fixing member 2, the claw portions 34 and 35 abut against the lower surface of the fixing member 2 in the middle of the connecting member 3. Further displacement is prevented. Thereby, the excessive displacement to the fixing member 2 side of the connection member 3 can be prevented, and the operativity of the fixing tool 1 improves. Further, the separation distance D5 is preferably equal to or shorter than the length of the through hole 210 in the X-axis direction. Thereby, the connecting member 3 can be smoothly inserted into the through hole 210. In addition, although a pair of claw parts 36 and 37 are provided also in the upper end part of the inclination part 333, ie, the other end part of the connection part 33, a pair of claw parts 36 and 37 are a pair of claw parts 34 and 35, and Since it is the same structure, the description is abbreviate | omitted.

図2に示すように、4つのツメ部34〜37のうち、Y軸方向に離間する一対のツメ部34、36の先端同士の離間距離D6は、貫通孔210のY軸方向の長さよりも僅かに大きく設定されている。一対のツメ部35、37の先端同士の離間距離についても、これと同様である。これにより、後述するように、連結部材3を貫通孔210内に挿入した状態で、連結部材3を固定部材2側に変位させたときに、4つのツメ部34〜37が部材200の下面に確実に当接する。特に、ツメ部34、36が部材200の下面の貫通孔210に対して互いに反対側に当接する(ツメ部35、37についても同様である)ため、より確実に、固定対象物300を部材200に固定できる。   As shown in FIG. 2, among the four claw portions 34 to 37, the distance D6 between the tips of the pair of claw portions 34 and 36 that are separated in the Y-axis direction is larger than the length of the through-hole 210 in the Y-axis direction. It is set slightly larger. The same applies to the separation distance between the tips of the pair of claw portions 35 and 37. Thereby, as will be described later, when the connecting member 3 is displaced toward the fixing member 2 in a state where the connecting member 3 is inserted into the through hole 210, the four claw portions 34 to 37 are formed on the lower surface of the member 200. Abut securely. In particular, the claw portions 34 and 36 abut on the opposite sides with respect to the through-hole 210 on the lower surface of the member 200 (the same applies to the claw portions 35 and 37), so that the fixed object 300 is more reliably attached to the member 200. Can be fixed.

脚部31上端部(連結部33と反対側の端部)には、抜け落ち防止部38が設けられており、同様に、脚部32の上端部にも、抜け落ち防止部39が設けられている。これら抜け落ち防止部38、39は、ネジ穴331aとネジ4との螺合が誤って解除されたとき、もしくは固定具1の製造途中であってネジ4が取り付けられていない状態のときでも、固定部材2に連結部材3を係合させておく機能、すなわち、固定部材2からの連結部材3の脱落を防止する機能を有する。   A drop-off prevention unit 38 is provided at the upper end of the leg 31 (the end opposite to the connecting portion 33). Similarly, a drop-off prevention unit 39 is provided at the upper end of the leg 32. . These drop-off prevention portions 38 and 39 are fixed even when the screw hole 331a and the screw 4 are accidentally released or when the fixing device 1 is being manufactured and the screw 4 is not attached. The member 2 has a function of engaging the connecting member 3, that is, a function of preventing the connecting member 3 from falling off the fixing member 2.

図1に示すように、抜け落ち防止部38、39は、それぞれ、薄い板状をなし、主面(厚さ方向に対向する一対の面)がXZ平面と平行に配置されている。また、図3に示すように、抜け落ち防止部38の幅(X軸方向の長さ)W6は、切り欠き22の幅W2よりも大きく設定されており、同様に、抜け落ち防止部39の幅(X軸方向の長さ)W7は、切り欠き23の幅W4よりも大きく設定されている。そのため、抜け落ち防止部38、39が固定部材2の上面と当接することにより、連結部材3の固定部材2からの抜け落ちが防止される。   As shown in FIG. 1, the drop-off prevention portions 38 and 39 each have a thin plate shape, and the main surfaces (a pair of surfaces opposed in the thickness direction) are arranged in parallel with the XZ plane. Further, as shown in FIG. 3, the width (length in the X-axis direction) W6 of the drop-off prevention part 38 is set larger than the width W2 of the notch 22, and similarly, the width ( The length in the X-axis direction) W7 is set to be larger than the width W4 of the notch 23. Therefore, the drop-off prevention portions 38 and 39 are in contact with the upper surface of the fixing member 2, thereby preventing the connecting member 3 from falling off the fixing member 2.

以上、連結部材3を構成する一対の脚部31、32、連結部33、ツメ部34〜37および一対の抜け落ち防止部38、39についてそれぞれ詳細に説明した。これら各構成要素は、例えば、1枚の薄い板部材を所望の外形形状に加工し、その後所定箇所で屈曲させることにより、一体的に形成することができる。これにより、連結部材3を簡単に製造することができる。連結部材3の構成材料は、特に限定されないが、比較的硬質な材料であるのが好ましく、例えば、アルミニウム、銅等の金属材料を用いることができる。   The pair of leg portions 31 and 32, the coupling portion 33, the claw portions 34 to 37, and the pair of dropout prevention portions 38 and 39 constituting the coupling member 3 have been described in detail above. Each of these components can be integrally formed by, for example, processing a thin plate member into a desired outer shape and then bending it at a predetermined location. Thereby, the connection member 3 can be manufactured easily. The constituent material of the connecting member 3 is not particularly limited, but is preferably a relatively hard material. For example, a metal material such as aluminum or copper can be used.

ネジ4は、前述したように、固定部材2に形成された挿通孔21に螺合せずに回転自在に挿通されているとともに、連結部材3の螺合部331に形成されたネジ穴331aに螺合している。ネジ4の長さは、連結部材3の螺合部331を固定部材2から最も離間させた状態、すなわち、抜け落ち防止部38、39を固定部材2に当接させた状態で、ネジ穴331aとの螺合が解除されない長さに設定されている。   As described above, the screw 4 is rotatably inserted without being screwed into the insertion hole 21 formed in the fixing member 2 and is screwed into the screw hole 331a formed in the screwing portion 331 of the connecting member 3. Match. The length of the screw 4 is the same as that of the screw hole 331a in a state where the screwing portion 331 of the connecting member 3 is farthest from the fixing member 2, that is, in a state where the dropout prevention portions 38 and 39 are in contact with the fixing member 2. The length is set so that the screwing is not released.

ここで、ネジ4が固定部材2に形成された挿通孔21に螺合せずに回転自在に挿通されている状態では、ネジ4および連結部材3が一体的に、固定部材2に対してZ軸方向に自由に変位することができる。このような変位が生じると、連結部材3を貫通孔210に挿入しづらくなるおそれがあるため、本実施形態の固定具1では、前記変位を防止するために、ネジ4に変位防止部材5を取り付けている。   Here, in a state where the screw 4 is rotatably inserted without being screwed into the insertion hole 21 formed in the fixing member 2, the screw 4 and the connecting member 3 are integrated with the fixing member 2 in the Z axis. It can be freely displaced in the direction. If such a displacement occurs, it may be difficult to insert the connecting member 3 into the through hole 210. Therefore, in the fixture 1 of the present embodiment, the displacement preventing member 5 is attached to the screw 4 in order to prevent the displacement. It is attached.

図5に示すように、変位防止部材5は、例えば、Eリング等のネジ4の軸に固定可能な部材で構成されている。変位防止部材5は、ネジ4の軸の基端部に固定されており、変位防止部材5とネジ4の頭とで固定部材2を挟み込んでいる。これにより、ネジ4がZ軸方向に変位できなくなり、連結部材3のZ軸方向の自由な変位を規制することができる。すなわち、ネジ4の回転によらなければ、連結部材3を固定部材2に対してZ軸方向に変位させることができない構成となる。このような構成とすることにとり、連結部材3を容易に貫通孔210に挿入することができる。   As shown in FIG. 5, the displacement preventing member 5 is configured by a member that can be fixed to the shaft of the screw 4 such as an E-ring, for example. The displacement preventing member 5 is fixed to the base end portion of the shaft of the screw 4, and the fixing member 2 is sandwiched between the displacement preventing member 5 and the head of the screw 4. Thereby, the screw 4 cannot be displaced in the Z-axis direction, and the free displacement of the connecting member 3 in the Z-axis direction can be restricted. In other words, the connection member 3 cannot be displaced in the Z-axis direction with respect to the fixed member 2 unless the screw 4 is rotated. By adopting such a configuration, the connecting member 3 can be easily inserted into the through hole 210.

以上、固定具1の構成について詳細に説明した。
次いで、図6および図7に基づいて、固定具1の使用方法について説明する。
The configuration of the fixture 1 has been described in detail above.
Next, a method of using the fixture 1 will be described based on FIGS. 6 and 7.

まず、ネジ4を回転させ、図6(A)に示すように、連結部材3の螺合部331を固定部材2から最も離間させた状態、すなわち抜け落ち防止部38、39が固定部材2に当接する状態とする。次いで、連結部材3を部材200の貫通孔210に挿入し、図6(B)に示すように、ツメ部34〜37を部材200の下面側に位置させる。なお、連結部材3を貫通孔210に挿入する際、ツメ部34〜37は、貫通孔210の側面と当接することによって内側へ向けて撓み、貫通孔210を通過した後、速やかに元の状態(貫通孔210を通過する前の状態)に復帰する。   First, the screw 4 is rotated, and as shown in FIG. 6 (A), the threaded portion 331 of the connecting member 3 is farthest from the fixing member 2, that is, the drop-off preventing portions 38 and 39 are in contact with the fixing member 2. Make contact. Next, the connecting member 3 is inserted into the through hole 210 of the member 200, and the claw portions 34 to 37 are positioned on the lower surface side of the member 200 as shown in FIG. In addition, when inserting the connection member 3 in the through-hole 210, the nail | claw parts 34-37 bend inward by contact | abutting with the side surface of the through-hole 210, and after passing through the through-hole 210, it immediately returns to the original state. It returns to the state before passing through the through hole 210.

次いで、ネジ4を前記と反対側に回転させ、連結部材3の螺合部331を固定部材2側に変位させる。すると、図7(A)に示すように、固定部材2と4つのツメ部34〜37の離間距離が縮まり、固定部材2の下面が部材200の上面に当接するとともに、4つのツメ部34〜37が部材200の下面と当接した状態となる。これにより、ツメ部34〜37によって固定部材2が部材200に連結され、固定対象物300が部材200に固定される。   Next, the screw 4 is rotated to the opposite side, and the screwing portion 331 of the connecting member 3 is displaced to the fixing member 2 side. Then, as shown in FIG. 7A, the separation distance between the fixing member 2 and the four claw portions 34 to 37 is shortened, the lower surface of the fixing member 2 comes into contact with the upper surface of the member 200, and the four claw portions 34 to 34 are connected. 37 comes into contact with the lower surface of the member 200. Thereby, the fixing member 2 is connected to the member 200 by the claw portions 34 to 37, and the fixing object 300 is fixed to the member 200.

なお、固定部材2の下面が部材200の上面に当接するとともに、ツメ部34〜37が部材200の下面と当接した状態となってからも、さらにネジ4を回転させ、螺合部331を固定部材2に接近させてもよい。部材200と各ツメ部34〜37の硬さの関係等によっては、図7(B)に示すように、ツメ部34〜37が部材200に食い込んだり、図7(C)に示すように、ツメ部34〜37が変形したりし、より強固に固定対象物300を部材200に固定することができる。
以上、本実施形態について説明したが、以下、変形例を示す。
Even when the lower surface of the fixing member 2 is in contact with the upper surface of the member 200 and the tabs 34 to 37 are in contact with the lower surface of the member 200, the screw 4 is further rotated to The fixing member 2 may be approached. Depending on the relationship between the hardness of the member 200 and the claw portions 34 to 37, as shown in FIG. 7B, the claw portions 34 to 37 bite into the member 200, or as shown in FIG. The nail | claw parts 34-37 deform | transform and can fix the fixed target object 300 to the member 200 more firmly.
Although the present embodiment has been described above, modifications will be described below.

図8に示すように、固定対象物300のベース320は、長尺状をなしており、その両端部が筐体310から突出している。そして、ベース320の一端部は、前述した固定具1の固定部材2を構成している。一方、ベース320の他端部は、ベース320の厚さ方向に湾曲または屈曲する変形部321を構成している。変形部321の先端部321aは、その主面がXY平面と平行となるように配置されている。この先端部321aの上面には、ゴム材料等で構成された弾性体322が設けられている。このような変形部321では、弾性体322の上面と、ベース320の中央部323とのZ軸方向の離間距離D8が、部材200の厚さよりも若干短く設定されている。   As shown in FIG. 8, the base 320 of the fixed object 300 has a long shape, and both end portions thereof protrude from the housing 310. One end portion of the base 320 constitutes the fixing member 2 of the fixing tool 1 described above. On the other hand, the other end portion of the base 320 constitutes a deformed portion 321 that is curved or bent in the thickness direction of the base 320. The distal end portion 321a of the deformable portion 321 is disposed so that its main surface is parallel to the XY plane. An elastic body 322 made of a rubber material or the like is provided on the upper surface of the tip portion 321a. In such a deformable portion 321, the distance D <b> 8 in the Z-axis direction between the upper surface of the elastic body 322 and the central portion 323 of the base 320 is set slightly shorter than the thickness of the member 200.

部材200には、固定具1の連結部材3が挿入される貫通孔210の他に、変形部321が挿入される貫通孔220が形成されている。固定対象物300は、このような部材200に対して次のように固定される。   The member 200 is formed with a through hole 220 into which the deformable portion 321 is inserted, in addition to the through hole 210 into which the connecting member 3 of the fixture 1 is inserted. The fixed object 300 is fixed to such a member 200 as follows.

図9(A)に示すように、まず、部材200に対して固定対象物300を傾けた状態で、貫通孔220に変形部321を挿通する。次いで、図9(B)に示すように、固定具1の連結部材3をもう一方の貫通孔210に挿通する。そして、前述したように、固定具1を締め付け固定対象物300を部材200に固定する。この状態では、変形部321に設けられた弾性体322が厚さ方向に収縮し、さらには変形部321が厚さ方向に撓んでいるため、これらが自然状態に復帰しようとする力(反発力)が発生し、当該反発力によって、固定対象物300が部材200に対してより強固に固定される。   As shown in FIG. 9A, first, the deformable portion 321 is inserted through the through hole 220 in a state where the fixed object 300 is inclined with respect to the member 200. Next, as shown in FIG. 9B, the connecting member 3 of the fixture 1 is inserted into the other through hole 210. Then, as described above, the fixture 1 is tightened to fix the fixing object 300 to the member 200. In this state, the elastic body 322 provided in the deformable portion 321 contracts in the thickness direction, and further, the deformable portion 321 is bent in the thickness direction. ) Occurs, and the fixed object 300 is more firmly fixed to the member 200 by the repulsive force.

次に、本発明の固定具の第2実施形態を説明する。
Second Embodiment
Next, a second embodiment of the fixture of the present invention will be described.

以下、第2実施形態について説明するが、前述した第1実施形態との相違点を中心に説明し、同様の事項については、その説明を省略する。   In the following, the second embodiment will be described, but the description will focus on the differences from the first embodiment described above, and description of similar matters will be omitted.

本実施形態の固定具1Aは、連結部材3Aが固定部材2に固定されていること、連結部材3Aが有する脚部31A、32Aが変形すること以外は、前述した第1実施形態と同様である。なお、前述した第1実施形態と同様の構成には、同一符号を付してある。   The fixing tool 1A of the present embodiment is the same as that of the first embodiment described above except that the connecting member 3A is fixed to the fixing member 2 and the leg portions 31A and 32A of the connecting member 3A are deformed. . In addition, the same code | symbol is attached | subjected to the structure similar to 1st Embodiment mentioned above.

図10に示すように、固定具1Aが有する連結部材3Aは、固定部材2に固定されている。固定方法としては特に限定されず、例えば、抜け落ち防止部38、39と固定部材2とを溶接してもよいし、接着剤を用いて接合してもよい。   As shown in FIG. 10, the connecting member 3 </ b> A included in the fixing tool 1 </ b> A is fixed to the fixing member 2. It does not specifically limit as a fixing method, For example, the drop-off prevention parts 38 and 39 and the fixing member 2 may be welded, and you may join using an adhesive agent.

脚部31A、32Aは、それぞれ、内側に屈曲する略「く」字状をなしている。脚部31A、32Aの屈曲部は、他の部分よりも脆弱に形成されており、この屈曲部を中心に折れ曲がるように容易に変形する。   Each of the leg portions 31A and 32A has a substantially “<” shape that is bent inward. The bent portions of the leg portions 31A and 32A are formed to be more fragile than the other portions, and are easily deformed so as to be bent around the bent portion.

図11に示すように、固定具1Aでは、連結部材3Aの螺合部331を固定部材2に接近させるためにネジ4を回転させると、各脚部31A、32Aのその屈曲部を中心とした屈曲変形を伴って、螺合部331が固定部材2に接近する。これにより、固定部材2の下面が部材200の上面に当接するとともに、4つのツメ部34〜37が部材200の下面と当接した状態となり、固定対象物300が部材200に固定される。   As shown in FIG. 11, in the fixture 1A, when the screw 4 is rotated in order to make the screwing portion 331 of the connecting member 3A approach the fixing member 2, the bent portions of the leg portions 31A and 32A are centered. The screwing portion 331 approaches the fixing member 2 with bending deformation. As a result, the lower surface of the fixing member 2 comes into contact with the upper surface of the member 200 and the four claw portions 34 to 37 come into contact with the lower surface of the member 200, and the fixing object 300 is fixed to the member 200.

以上、本発明の固定具について、図示の実施形態に基づいて説明したが、本発明はこれに限定されるものではない。例えば、本発明の固定具では、各部の構成は、同様の機能を発揮する任意の構成のものに置換することができ、また、任意の構成を付加することもできる。   As mentioned above, although the fixing tool of this invention was demonstrated based on embodiment of illustration, this invention is not limited to this. For example, in the fixture of the present invention, the configuration of each part can be replaced with an arbitrary configuration that exhibits the same function, and an arbitrary configuration can be added.
