　この種のプロファイル用コネクタの構成を開示するものとして、例えば、特許文献１、特許文献２、等がある。
　尚、特許文献１、特許文献２は何れも本件特許出願人によるものである。 Patent Documents 1 and 2, for example, disclose the configuration of this type of profile connector.
Both Patent Document 1 and Patent Document 2 are by the present patent applicant.
　特許文献１に開示されているプロファイル用コネクタは次のような構成をなしている。まず、一対のコネクタ要素が設けられていて、上記コネクタ要素は頭部と押圧部とから構成されている。上記頭部は分割面部を備えていて、この分割面部の先端には把持爪部が設けられている。上記把持爪部が上記第１プロファイルの被把持部の片側に係合する。上記頭部には貫通孔が穿孔されている。上記押圧部は上記第２プロファイル内に挿入される。上記一対のコネクタ要素は同様の構成になっている。 The profile connector disclosed in Patent Document 1 has the following configuration. First, a pair of connector elements are provided, and the connector elements are composed of a head portion and a pressing portion. The head has a split surface portion, and a gripping claw portion is provided at the tip of the split surface portion. The gripping claw engages one side of the gripped portion of the first profile. A through hole is drilled in the head. The pressing portion is inserted into the second profile. The pair of connector elements are of similar construction.
　上記第１プロファイルと第２プロファイルは上記プロファイル用コネクタを介して次のようにして連結される。まず、一対のコネクタ要素をそれぞれの頭部の分割面部を合わせて組み合わせる。その状態で一対のコネクタ要素のそれぞれの頭部に穿孔された貫通孔の片側にナットをセットして反対側からボルトを挿し込んで上記ナットに螺合していき、上記一対のコネクタ要素を緩く連結した状態とする。その状態で一対のコネクタ要素のそれぞれの頭部の把持爪部を第１プロファイルの被把持部の両側端に係合させる。同時に、押圧部を組み合わせた部分を上記第２プロファイル内に挿入する。 The first profile and the second profile are connected via the profile connector as follows. First, a pair of connector elements are assembled by aligning the split surface portions of the respective heads. In this state, a nut is set on one side of the through hole drilled in the head of each of the pair of connector elements, and a bolt is inserted from the opposite side and screwed into the nut to loosen the pair of connector elements. Connected. In this state, the gripping claws on the heads of the pair of connector elements are engaged with both side ends of the gripped portion of the first profile. At the same time, the combined portion of the pressing portion is inserted into the second profile.
　その状態で上記ボルトを上記ナットにさらに螺合していく。上記ボルトを上記ナットに螺合していくと、上記一対のコネクタ要素が接近していき上記一対の把持爪部によって上記第１プロファイルの被把持部が挟持される。同時に上記第２プロファイル内に挿入された一対の押圧部が相互に離間されていき上記第２プロファイルの内周面に押し付けられていく。このような作用によって、上記第１プロファイルと第２プロファイルがプロファイル用コネクタを介して連結される。 In that state, further screw the bolt into the nut. As the bolt is screwed into the nut, the pair of connector elements approaches and the gripped portion of the first profile is gripped by the pair of gripping claws. At the same time, the pair of pressing portions inserted into the second profile are separated from each other and pressed against the inner peripheral surface of the second profile. By such action, the first profile and the second profile are connected via the profile connector.
　尚、特許文献２に開示されているプロファイル用コネクタも同様の構成になっている。 The profile connector disclosed in Patent Document 2 also has a similar configuration.
特許第５９８９５０２号公報Japanese Patent No. 5989502 特許第６７７８９５３号公報Japanese Patent No. 6778953
　上記従来の構成によると次のような問題があった。
　まず、一対のコネクタ要素の頭部と第２プロファイルの端面との間に隙間が空いてしまい異物の侵入が懸念されるという問題があった。これは次のような理由による。各コネクタ要素の頭部の張出下面は、一見すると平坦面にみえるが型抜きを考慮して僅かなテーパ、具体的には、０．５程度のテーパが設けられている。この僅かなテーパが起因してコネクタ要素の頭部と第２プロファイルの端面との間に隙間が空いてしまうことになる。
　又、別の問題として、上記一対のコネクタ要素の挿入部の第２プロファイルへの挿入性が悪いという問題があった。これは上記一対のコネクタ要素の挿入部の外径と第２プロファイルの内径との間に十分な寸法差がないことに起因する。 The above-described conventional configuration has the following problems.
First, there is a problem that there is a gap between the head portions of the pair of connector elements and the end face of the second profile, and there is concern that foreign matter may enter. This is for the following reasons. The projecting lower surface of the head of each connector element looks flat at first glance, but is slightly tapered, specifically, about 0.5, in consideration of die-cutting. This slight taper results in a gap between the head of the connector element and the end face of the second profile.
Another problem is that the inserting portions of the pair of connector elements are difficult to insert into the second profile. This is due to insufficient dimensional difference between the outer diameter of the insertion portion of the pair of connector elements and the inner diameter of the second profile.
　本発明はこのような点に基づいてなされたものでその特徴とするところは、一対のコネクタ要素の頭部とプロファイルとの間の隙間の発生をなくし、且つ、一対のコネクタ要素の挿入部のプロファイルへの挿入性を向上させることができるプロファイル連結用コネクタを提供することにある。 The present invention has been made based on these points, and is characterized by eliminating the occurrence of gaps between the heads and profiles of the pair of connector elements, and eliminating the insertion portions of the pair of connector elements. To provide a profile connecting connector capable of improving insertability into a profile.

　以下、図１乃至図１４を参照して本発明の一の実施の形態について説明する。
　図１３、図１４に示すように、本実施の形態によるプロファイル用コネクタ１は、例えば、第１プロファイル３と第２プロファイル５を垂直に指向させた状態で連結・固定する際に使用される。 An embodiment of the present invention will be described below with reference to FIGS. 1 to 14. FIG.
As shown in FIGS. 13 and 14, the profile connector 1 according to this embodiment is used, for example, when connecting and fixing the first profile 3 and the second profile 5 in a vertically oriented state.
　上記第１プロファイル３、上記第２プロファイル５は、同一の横断面形状（略円形の横断面形状）で、長さが適宜に設定された、例えば、アルミニウム製の押出成形品である。上記第１プロファイル３は中空状をなし外周面には溝７と被把持部９が周方向等間隔に４個ずつ交互に長手方向に延長・形成されている。上記被把持部９の左右両端にはエッジ１１、１１が張り出した状態で設けられている。 The first profile 3 and the second profile 5 have the same cross-sectional shape (substantially circular cross-sectional shape) and are appropriately set lengths, for example, aluminum extrusions. The first profile 3 has a hollow shape, and four grooves 7 and gripped portions 9 are alternately formed in the longitudinal direction at equal intervals in the circumferential direction on the outer peripheral surface. Edges 11, 11 are provided at both left and right ends of the gripped portion 9 in a state of protruding.
　又、上記第１プロフィル３の内周面には係合凹部１５が周方向等間隔で４個設けられている。上記係合凹部１５は上記被把持部９に対応する内側に設けられている。
　尚、上記第２プロファイル５も同様の構成をなしており、図中同一部分には同一符号を付して示しその説明を省略する。 Four engaging recesses 15 are provided on the inner peripheral surface of the first profile 3 at regular intervals in the circumferential direction. The engaging recess 15 is provided inside corresponding to the gripped portion 9 .
The second profile 5 has the same structure, and the same reference numerals are given to the same parts in the figure, and the explanation thereof will be omitted.
　上記プロファイル連結用コネクタ１は、図１３、図１４に示すように、一対のコネクタ要素２１、２３と、ボルト２５とから構成されている。上記コネクタ要素２１は、図９、図１０に示すように、頭部２７と挿入部２９とから構成されている。上記頭部２７には上記コネクタ要素２３側に対向する合わせ面３１が設けられており、又、上記第１プロファイル３側に対向する合わせ面３３が設けられている。上記頭部２７には上記合わせ面３１から横方向に貫通する貫通孔３５が穿孔されている。この貫通孔３５内に上記ボルト２５が外側から挿し込まれる。
　尚、上記ボルト２５は図示しない六角レンチを凹部２５ａに挿し込んで回転操作するタイプのものである。 The profile connecting connector 1 comprises a pair of connector elements 21 and 23 and a bolt 25, as shown in FIGS. The connector element 21 is composed of a head portion 27 and an insertion portion 29, as shown in FIGS. The head 27 is provided with a mating surface 31 facing the connector element 23 side and a mating surface 33 facing the first profile 3 side. A through hole 35 is formed in the head portion 27 so as to pass through the mating surface 31 in the lateral direction. The bolt 25 is inserted into the through hole 35 from the outside.
The bolt 25 is of a type in which a hexagonal wrench (not shown) is inserted into the recess 25a and rotated.
　上記合わせ面３３の外周端には係合爪４１が突設されている。この係合爪４１が上記第１プロファイル３の被把持部９の片側のエッジ１１に係合される。上記合わせ面３１の左右両端には重合凸部４３、４３が周方向に張り出した状態で突設されている。又、上記合わせ面３１には肉抜き凹部４５、４５が形成されている。又、上記合わせ面３３の中央には凹部４７が形成されていて、上記係合爪４１にも凹部４９が形成されている。又、上記頭部２７の張出部下面５１は、図１に示すように、テーパ０°の平坦に形成されていて、図１４に示すように、上記第２プロファイル５の端面に対して密着した状態で設置される。
　尚、既に説明した特許文献１の場合も、一見すると、頭部の張出下面が平坦にみえるが、実際は型抜きを考慮して０．５°程度のテーパが設けられているため、第２プロファイル５の端面に対して密着させることはできない。
　この点に関して詳しく説明する。
　図１４に示すように、コネクタ要素２１の貫通孔３５の内径は外側に向かってテーパ角度α°（例えば、１．５°）で徐々に拡径されている。これに対して、従来はコネクタ要素２３の張出下面５１も図中仮想線で示すようにテーパ角度β°（例えば、０．５°）の傾斜面になっていた。これは型抜きを考慮し設けられている。
　これに対して、本実施の形態の場合には、上記傾斜角度α°を従来より大きくし、その代わりに、上記テーパ角度β°を０°としたものである。この場合には型抜き性を損なうことなく第２プロファイル５の端面への密着度を高めることができる。 An engaging claw 41 is projected from the outer peripheral end of the mating surface 33 . This engaging claw 41 is engaged with the edge 11 on one side of the gripped portion 9 of the first profile 3 . Overlapping protrusions 43, 43 protrude in the circumferential direction at both left and right ends of the mating surface 31. As shown in FIG. Further, lightening recesses 45, 45 are formed in the mating surface 31. As shown in FIG. A recess 47 is formed in the center of the mating surface 33, and a recess 49 is formed in the engaging claw 41 as well. 1, the lower surface 51 of the projecting portion of the head 27 is formed flat with a taper of 0°, and is in close contact with the end surface of the second profile 5 as shown in FIG. It is installed in the state where
In addition, in the case of Patent Document 1 already described, at first glance, the overhanging lower surface of the head appears flat, but in reality it is tapered at about 0.5° in consideration of die-cutting. Close contact with the end face of the profile 5 is not possible.
This point will be described in detail.
As shown in FIG. 14, the inner diameter of the through hole 35 of the connector element 21 gradually expands outward at a taper angle α° (eg, 1.5°). On the other hand, conventionally, the overhanging lower surface 51 of the connector element 23 was also an inclined surface with a taper angle of β° (for example, 0.5°) as indicated by the phantom line in the figure. This is provided in consideration of die cutting.
On the other hand, in the case of the present embodiment, the inclination angle α° is made larger than the conventional one, and instead, the taper angle β° is set to 0°. In this case, it is possible to increase the adhesion of the second profile 5 to the end face without impairing the mold-releasability.
　上記挿入部２９は螺旋形状に形成されていて螺旋状係合面５３を備えている。又、上記コネクタ要素２３側に対向する側に押圧凸部５５が突設されている。この押圧凸部５３が上記第２プロファイル５の内面の係合凹部１５に押圧係合される。又、上記合わせ面３１であって上記貫通孔３５の周囲にはテーパ形状の凸部５７が突設されている。又、挿入部２９の先端にはテーパ状の先細部５９が設けられている。 The insertion portion 29 is formed in a helical shape and has a helical engaging surface 53 . Further, a pressing protrusion 55 is provided on the side facing the connector element 23 side. The pressing protrusion 53 is pressed and engaged with the engaging recess 15 on the inner surface of the second profile 5 . A tapered convex portion 57 is provided around the through hole 35 on the mating surface 31 . A tapered tapered portion 59 is provided at the distal end of the insertion portion 29 .
　上記頭部２７の外周面の形状であるが、貫通孔３５が設けられている部位は凸部６１となっていて、この凸部６１の左右両側には凹部６３、６３が形成されている。図１３に示すように、上記凸部６１の下端の幅ｂ１は上記第１プロファイル３の被把持部９の幅ｂ２と同じに設定されている。又、上記凹部６３の下端の幅ｂ３は第１プロフィル３の溝７の幅ｂ４と同じに設定されている。
　尚、上記凹部６３の反凸部５１側には半割凸部６１´が設けられていて、後述するコネクタ要素２３側にも同様の半割凸部６１´が設けられていて、合わせられることにより凸部６１となる。 Regarding the shape of the outer peripheral surface of the head portion 27, the portion where the through hole 35 is provided is a convex portion 61, and concave portions 63, 63 are formed on both left and right sides of this convex portion 61. As shown in FIG. As shown in FIG. 13, the width b1 of the lower end of the convex portion 61 is set to be the same as the width b2 of the gripped portion 9 of the first profile 3. As shown in FIG. The width b 3 of the lower end of the recess 63 is set to be the same as the width b 4 of the groove 7 of the first profile 3 .
A half projection 61' is provided on the side of the recess 63 opposite to the projection 51, and a similar half projection 61' is also provided on the connector element 23 side, which will be described later. It becomes the convex part 61 by this.
　上記コネクタ要素２３も基本的には上記コネクタ要素２１と同じ構成になっており、図中同一部分には同一符号を付して示しその説明を省略する。
　但し、頭部２７には合わせ面３１を貫通する貫通孔は形成されておらず、代わりに雌ねじ部７１が形成されている。この雌ねじ部７１は上記合わせ面３１側から所定深さ設けられていて、図１２に示すように、反対側に貫通してはいない。又、上記合わせ面３１であって上記雌ねじ部７１の周囲にはテーパ状の凹部７３が形成されている。又、頭部２７の上記コネクタ要素２１側の左右の角部には重合凹部７５、７５が形成されている。上記重合凹部７５は角部に面取り加工を施すことにより設けられている。これら重合凹部７５、７５に既に説明したコネクタ要素２１の重合凸部４３、４３が重合する。 The connector element 23 has basically the same structure as that of the connector element 21, and the same parts in the figure are indicated by the same reference numerals, and the description thereof is omitted.
However, the head portion 27 is not formed with a through hole penetrating the mating surface 31, and is instead formed with a female screw portion 71. As shown in FIG. The female screw portion 71 is provided to a predetermined depth from the side of the mating surface 31, and as shown in FIG. 12, does not penetrate to the opposite side. A tapered concave portion 73 is formed around the female screw portion 71 on the mating surface 31 . Overlapping recesses 75, 75 are formed at the left and right corners of the head 27 on the connector element 21 side. The overlapping concave portion 75 is provided by chamfering the corner portion. The overlapped projections 43, 43 of the connector element 21 already described overlap with these overlapped recesses 75, 75. As shown in FIG.
　以上の構成を基にその作用を説明する。
　図１３、図１４に示すように、本実施の形態によるプロファイル用コネクタ１を使用して、第１プロファイル３に対して第２プロファイル５を直交する方向から指向させて連結する。
　まず、コネクタ要素２１の貫通孔３５に外側からボルト２５を挿し込んでコネクタ要素２３の雌ねじ部６１に少し螺合させ、コネクタ要素２１とコネクタ要素２３を緩く連結した状態とする。その際、コネクタ要素２１の合わせ面３１とコネクタ要素２３の合わせ面３１を対向させ、且つ、コネクタ要素２１の螺旋状係合面５３とコネクタ要素２３の螺旋状係合面５３を係合させる。 The operation will be described based on the above configuration.
As shown in FIGS. 13 and 14, using the profile connector 1 according to the present embodiment, the second profile 5 is oriented perpendicular to the first profile 3 and connected.
First, the bolt 25 is inserted into the through hole 35 of the connector element 21 from the outside and slightly screwed into the female threaded portion 61 of the connector element 23 to loosely connect the connector elements 21 and 23 . At that time, the mating surface 31 of the connector element 21 and the mating surface 31 of the connector element 23 are made to face each other, and the spiral engaging surface 53 of the connector element 21 and the spiral engaging surface 53 of the connector element 23 are engaged.
　次に、コネクタ要素２１の挿入部２９とコネクタ要素２３の挿入部２９を第２プロファイル５の内部に挿入する。又、コネクタ要素２１の係合爪４１とコネクタ要素２３の係合爪４１とによって第１プロファイル３のプロファイル側被把持部９のエッジ１１、１１を両側から挟持する。その状態で上記ボルト２５をさらに螺合させていく。 Next, the insertion portion 29 of the connector element 21 and the insertion portion 29 of the connector element 23 are inserted inside the second profile 5 . Further, the edges 11, 11 of the profile-side gripped portion 9 of the first profile 3 are clamped from both sides by the engaging claws 41 of the connector element 21 and the engaging claws 41 of the connector element 23. As shown in FIG. In this state, the bolt 25 is further screwed.
　上記ボルト２５のさらなる螺合により上記係合爪４１、４１は上記プロファイル側被把持部９の両端のエッジ１１、１１に強固に係合する。一方、挿入部２９、２９の押圧凸部５５、５５は相互に離間する方向に張り出されていき、第２プロファイル５の係合凹部１５、１５に係合して強固に押し付けられる。それによって、第１プロファイル３と第２プロファイル５がプロファイル用コネクタ１を介して連結される。
　その際、コネクタ要素２１の凸部５７はコネクタ要素２３の凹部７３に係合する。又、コネクタ要素２１の重合凸部４３、４３はコネクタ要素２３の重合凹部７５、７５に重合される。 Further screwing of the bolt 25 firmly engages the engaging claws 41, 41 with the edges 11, 11 at both ends of the profile-side gripped portion 9. As shown in FIG. On the other hand, the pressing protrusions 55, 55 of the insertion sections 29, 29 project in the direction of separating from each other, engage with the engaging recesses 15, 15 of the second profile 5, and are firmly pressed. Thereby, the first profile 3 and the second profile 5 are connected via the profile connector 1 .
At that time, the protrusion 57 of the connector element 21 engages the recess 73 of the connector element 23 . Also, the overlapping projections 43 , 43 of the connector element 21 are overlapped with the overlapping recesses 75 , 75 of the connector element 23 .
　以上本実施の形態によると次のような効果を奏することができる。
　まず、コネクタ要素２１、２３の連結に際してボルト２５のみを使用するナットレス構造を採用しているので、作業時におけるナットの脱落といった問題もなく、締結作業の容易化、作業時間の短縮を図ることができる。
　又、コネクタ要素２３の雌ねじ部７１は合わせ面３１側にのみ開口した状態で設けられているので、コネクタ要素２３の外側からの異物の侵入を防止することができる。
　又、コネクタ要素２１側の凸部５７がコネクタ要素２３側の凹部７３に係合する関係にあるので、コネクタ要素２１とコネクタ要素２３の位置決めも容易であり、且つ、ボルト２５の雌ねじ部７１への螺合作業も容易である。
　又、コネクタ要素２１とコネクタ要素２３が締結された状態では、コネクタ要素２１側の重合凸部４３、４３が、コネクタ要素２３側の重合凹部７５、７５に重合されることになるので、コネクタ要素２１とコネクタ要素２３の合わせ面に隙間が空いてしまうようなことはなく、それによって、異物の侵入を防止することができる。
　又、コネクタ要素２１の張出下面５１とコネクタ要素２３の張出下面５１は共にテーパ０°の平坦面であるので、第２プロファイル５の端面に対して密着することになり、それによっても、異物の侵入を防止することができる。
　又、コネクタ要素２１、２３の頭部２７の凸部６１の下端の幅ｂ１は第1プロファイル３、第２プロファイル５の被把持部９の幅ｂ２と同じに設定されていて、且つ、凹部６３の下端の幅ｂ３は第1プロファイル３、第２プロファイル５の凹部７の幅ｂ４と同じに設定されているので、図１３、図１４に示すような状態で組み立てた場合に、凸部６１と被把持部９が連続した状態で組み立てられ、且つ、凹部６３と凹部７も連続した状態で組み立てられることになり、出っ張り部が発生しないので、組立後における引っ掛かり現象、例えば、作業員の衣服の引っ掛かり等を無くすことができる。
　それによって、頭部２７と第２プロファイル５との境界部に不連続部が発生することはなく、不連続部における異物の堆積をなくすことができ、それによっても、異物の侵入防止効果を得ることができる。
　又、コネクタ要素２１、２３の挿入部２９、２９の先端には先細部５９、５９が設けられているので、第２プロファイル５に対する挿入性も良好である。 As described above, according to the present embodiment, the following effects can be obtained.

In addition, since the female threaded portion 71 of the connector element 23 is provided in a state of being opened only on the mating surface 31 side, it is possible to prevent foreign matter from entering from the outside of the connector element 23 .
Further, since the convex portion 57 on the connector element 21 side is engaged with the concave portion 73 on the connector element 23 side, the connector element 21 and the connector element 23 can be easily positioned. screwing work is also easy.
In addition, when the connector element 21 and the connector element 23 are fastened together, the overlapping protrusions 43, 43 on the connector element 21 side overlap with the overlapping recesses 75, 75 on the connector element 23 side. There is no gap between the mating surfaces of 21 and connector element 23, thereby preventing entry of foreign matter.
Further, since both the projecting lower surface 51 of the connector element 21 and the projecting lower surface 51 of the connector element 23 are flat surfaces with a taper of 0°, they come into close contact with the end surface of the second profile 5. Intrusion of foreign matter can be prevented.
Further, the width b1 of the lower end of the convex portion 61 of the head portion 27 of the connector elements 21, 23 is set to be the same as the width b2 of the gripped portion 9 of the first profile 3 and the second profile 5, and Since the width b3 of the lower end of the recess 63 is set to be the same as the width b4 of the recess 7 of the first profile 3 and the second profile 5, when assembled in the state shown in FIGS. The projection 61 and the gripped portion 9 are assembled in a continuous state, and the recessed portion 63 and the recessed portion 7 are also assembled in a continuous state. It is possible to eliminate the catching of the staff's clothes.
As a result, no discontinuous portion is generated at the boundary between the head 27 and the second profile 5, and foreign matter can be prevented from accumulating in the discontinuous portion. be able to.
Further, since the tip ends of the insertion portions 29, 29 of the connector elements 21, 23 are provided with the tapered portions 59, 59, the insertability for the second profile 5 is also good.
