第２部材９は、その分割部６ａが互いに離れるように相対移動するよう、第２ガイド部材１１の第４の押圧部１１ｂに押される第４の被押圧部９ａを有している。この第２部材９は、一対設けられており、それら第２部材９、９は、その一方側で、前記第１部材８の他方側を挟むように位置している。ここで、第２部材９は、一方側の第２部材本体部９ｂと、他方側の前記分割部６ａとからなる。そして、第２部材本体部９ｂは、細長の略直方体形状をしている。そして、分割部６ａは、図１に示すように、第２部材本体部９ｂから、上下および互いに向かい合う側に幅広となるようにして延設されている。そして、この分割部６ａの、互いに向かい合う面に形成された傾斜面が、前記第４の被押圧部９ａとなっている。そして、この分割部６ａには、後述する弾性材１２が収容される収容部９ｃが形成されている。また、一方の第２部材９における第２部材本体部９ｂには、第１の孔９ｄが明けられている。そして、他方の第２部材９における第２部材本体部９ｂには、第２の孔９ｅが明けられている。さらに、その第２の孔９ｅの、背面側には、座ぐり孔９ｆが明けられており、この座ぐり孔９ｆに、前記第２の孔９ｅと連通するネジ孔９ｇを備えたナット９ｈが収容されている。 The 2nd member 9 has the 4th to-be-pressed part 9a pushed by the 4th press part 11b of the 2nd guide member 11 so that the division | segmentation part 6a may move relatively so that it may mutually separate. A pair of the second members 9 are provided, and the second members 9 and 9 are positioned so as to sandwich the other side of the first member 8 on one side thereof. Here, the 2nd member 9 consists of the 2nd member main-body part 9b of one side, and the said division part 6a of the other side. And the 2nd member main-body part 9b is carrying out the elongate substantially rectangular parallelepiped shape. And as shown in FIG. 1, the division part 6a is extended from the 2nd member main-body part 9b so that it may become wide up and down and the side which mutually faces. And the inclined surface formed in the mutually opposing surface of this division | segmentation part 6a is the said 4th to-be-pressed part 9a. And in this division | segmentation part 6a, the accommodating part 9c in which the elastic material 12 mentioned later is accommodated is formed. Further, a first hole 9d is opened in the second member main body portion 9b of the one second member 9. A second hole 9e is opened in the second member main body 9b of the other second member 9. Further, a counterbore 9f is opened on the back side of the second hole 9e, and a nut 9h provided with a screw hole 9g communicating with the second hole 9e is formed in the counterbore 9f. Contained.

そこで、前記一対の第２ガイド部材１１、１１は、その一方が、一対の第２部材９、９における第２部材本体部９ｂ、９ｂの上面に渡され、そして、他方が、一対の第２部材９、９における第２部材本体部９ｂ、９ｂの下面に渡される。そして、この第２ガイド部材１１の第３の被押圧部１１ａは、第１フレーム１と第２フレーム２とが接続される前においては、本体４の一方の端面４ａよりも突出している（図６参照）。また、前記第１ガイド部材１０は、前記取付ネジ７の第１の押圧部７ａと前記第１部材８の第２の被押圧部８ａとの間に位置するように配備される。そして、取付ネジ７は、その頭部７ｃが、本体４の孔４ｆと一方の第２部材９の第１の孔９ｄに挿入され、そして、雄ねじ部７ｂが、第１ガイド部材１０の孔１０ｃと第１部材８の孔８ｂと他方の第２部材９の第２の孔９ｅに挿入され、ナット９ｈに螺合する。 Therefore, one of the pair of second guide members 11, 11 is passed over the upper surfaces of the second member main body portions 9 b, 9 b of the pair of second members 9, 9, and the other is a pair of second guide members 9, 9. It passes over the lower surface of the 2nd member main-body parts 9b and 9b in the members 9 and 9. And the 3rd to-be-pressed part 11a of this 2nd guide member 11 protrudes rather than the one end surface 4a of the main body 4 before the 1st frame 1 and the 2nd frame 2 are connected (FIG. 6). Further, the first guide member 10 is disposed so as to be positioned between the first pressing portion 7 a of the mounting screw 7 and the second pressed portion 8 a of the first member 8. The mounting screw 7 has its head portion 7c inserted into the hole 4f of the main body 4 and the first hole 9d of one second member 9, and the male screw portion 7b is inserted into the hole 10c of the first guide member 10. Are inserted into the hole 8b of the first member 8 and the second hole 9e of the other second member 9, and screwed into the nut 9h.

また、この接続具３は、第１挿入部５を本体４とは反対側に付勢するための、弾性材１２を備えている。図示実施の形態においては、この弾性材１２は、コイルスプリング（板バネあるいはウレタン材であってもよい。）からなり、第２部材９、９の収容部９ｃ、９ｃに収容されて、第１部材８を、その他方側の端面８ｃを押すようにして付勢している。 In addition, the connector 3 includes an elastic material 12 for biasing the first insertion portion 5 to the side opposite to the main body 4. In the illustrated embodiment, the elastic material 12 is formed of a coil spring (may be a leaf spring or a urethane material), and is accommodated in the accommodating portions 9c, 9c of the second members 9, 9, so that the first The member 8 is urged so as to push the end surface 8c on the other side.

次に、以上の構成からなる接続具３の作用効果について説明する。この接続具３によると、第１フレーム１と第２フレーム２とを接続するにあたって、図３に示すように、本体４を、その一方の端面４ａが第１フレーム１の一の面１ａと対向するように、そして、他方の端面４ｂが第２フレーム２の端面２ａと対向するように配置する。そして、図５および図６に示すように、本体４の一方の端面４ａから突出する第１挿入部５を、第１フレーム１の溝１０１に、長手方向の側端部開口から差し入れて挿入するとともに、本体４の他方の端面４ｂから突出する第２挿入部６（分割部６ａ、６ａ）を、第２フレーム２の通孔２０３に挿入する。このとき、張出し部５ａを有する第１挿入部５は、弾性材１２によって、本体４から離れる側に付勢されているので、この第１挿入部５は、第１フレーム１の溝１０１に容易に挿入される。 Next, the effect of the connection tool 3 having the above configuration will be described. According to this connection tool 3, when connecting the first frame 1 and the second frame 2, as shown in FIG. 3, the main body 4 has one end face 4 a facing one surface 1 a of the first frame 1. Then, the other end face 4b is disposed so as to face the end face 2a of the second frame 2. Then, as shown in FIGS. 5 and 6, the first insertion portion 5 protruding from one end face 4 a of the main body 4 is inserted into the groove 101 of the first frame 1 by being inserted from the side end opening in the longitudinal direction. At the same time, the second insertion portion 6 (divided portions 6 a, 6 a) protruding from the other end surface 4 b of the main body 4 is inserted into the through hole 203 of the second frame 2. At this time, the first insertion portion 5 having the overhanging portion 5a is urged toward the side away from the main body 4 by the elastic material 12, so that the first insertion portion 5 can be easily inserted into the groove 101 of the first frame 1. Inserted into.

そこで、図７および図８に示すように、一本の取付ネジ７を、本体４の周面４ｃ側から回動操作すると（ねじ込むと）、第１の押圧部７ａが第１の被押圧部１０ａを押して、第１ガイド部材１０は、取付ネジ７の進む方向に移動する。この第１ガイド部材１０の移動により、第２の押圧部１０ｂが第２の被押圧部８ａを押して、第１部材８、すなわち第１挿入部５を本体４側に引き込む。こうして、その第１挿入部５の先端部分の張出し部５ａ、５ａが、第１フレーム１における溝１０１の突条部１０２、１０２の裏面を押圧し、第１挿入部５は、溝１０１に係止される。そして、第１部材８が引き込まれることで、第１フレーム１は、本体４に相対的に近づく。そこで、第２ガイド部材１１は、第３の被押圧部１１ａが第１フレーム１の一の面１ａ（第３の押圧部１ｃ）に押されて移動する。そして、この第２ガイド部材１１の移動により、第４の押圧部１１ｂが第４の被押圧部９ａを押して、第２部材９、９を、その分割部６ａ、６ａが互いに離れるように相対移動させる。こうして、それら分割部６ａ、６ａが、第２フレーム２の通孔２０３の内面を押圧し、分割部６ａ、６ａからなる第２挿入部６は、通孔２０３に係止される。このように、本体４に設けられた一本の取付ネジ７を、本体４の周面４ｃ側から回動操作することで、第１挿入部５が第１フレーム１の溝１０１に係止されるとともに、第２挿入部６が第２フレーム２の通孔２０３に係止されて、これら第１フレーム１と第２のフレーム２とが簡単に接続される。なお、このように第１フレーム１と第２フレーム２とが接続された状態では、取付ネジ７は、本体４の周面４ｃよりも沈んでおり、この取付ネジ７が周囲と干渉するのを避けることができる。 Therefore, as shown in FIGS. 7 and 8, when one mounting screw 7 is turned from the peripheral surface 4c side of the main body 4 (screwed), the first pressing portion 7a becomes the first pressed portion. 10a is pushed and the 1st guide member 10 moves to the direction which the attachment screw 7 advances. By the movement of the first guide member 10, the second pressing portion 10b presses the second pressed portion 8a, and the first member 8, that is, the first insertion portion 5 is pulled toward the main body 4 side. Thus, the overhanging portions 5 a and 5 a at the distal end portion of the first insertion portion 5 press the back surfaces of the protruding portions 102 and 102 of the groove 101 in the first frame 1, and the first insertion portion 5 is engaged with the groove 101. Stopped. And the 1st frame 1 approaches the main body 4 relatively by the 1st member 8 being drawn. Therefore, the second guide member 11 moves when the third pressed portion 11a is pressed by one surface 1a (third pressing portion 1c) of the first frame 1. Then, by the movement of the second guide member 11, the fourth pressing portion 11b presses the fourth pressed portion 9a, and the second members 9, 9 are relatively moved so that the divided portions 6a, 6a are separated from each other. Let Thus, the divided portions 6 a and 6 a press the inner surface of the through hole 203 of the second frame 2, and the second insertion portion 6 including the divided portions 6 a and 6 a is locked to the through hole 203. In this way, by rotating one mounting screw 7 provided on the main body 4 from the peripheral surface 4 c side of the main body 4, the first insertion portion 5 is locked in the groove 101 of the first frame 1. At the same time, the second insertion portion 6 is locked in the through hole 203 of the second frame 2 so that the first frame 1 and the second frame 2 are easily connected. In the state where the first frame 1 and the second frame 2 are connected in this way, the mounting screw 7 is submerged from the peripheral surface 4c of the main body 4, and the mounting screw 7 interferes with the surroundings. Can be avoided.

そして、第１フレーム１と第２フレーム２とを分離するには、取付ネジ７を、前記と逆方向に回動操作する（緩める）。こうすることで、第１挿入部５の、溝１０１への係止と、第２挿入部６の、通孔２０３への係止が解除される。そこで、第１挿入部５を溝１０１から外すとともに、第２挿入部６を通孔２０３から外す。こうして、接続具３は、第１フレーム１および第２フレーム２から取り外されて、それら第１フレーム１と第２フレーム２とが分離される。 And in order to isolate | separate the 1st frame 1 and the 2nd frame 2, the attachment screw 7 is rotationally operated in the direction opposite to the above (loosening). By doing so, the locking of the first insertion portion 5 to the groove 101 and the locking of the second insertion portion 6 to the through hole 203 are released. Therefore, the first insertion portion 5 is removed from the groove 101 and the second insertion portion 6 is removed from the through hole 203. Thus, the connector 3 is detached from the first frame 1 and the second frame 2, and the first frame 1 and the second frame 2 are separated.

また、第１フレーム１において、型材の溝１０１が、そのまま第１の開口部１ｂとなり、第２フレーム２において、型材の通孔２０３が、そのまま第２の開口部２ｂとなっている。そして、本体４の周面４ｃ側から取付ネジ７を回動操作することで、第１挿入部５が、第１の開口部１ｂとなった型材の溝１０１に係止され、第２挿入部６が、第２の開口部２ｂとなった型材の通孔２０３に係止されるることから、それら第１フレーム１と第２フレーム２とを接続するにあたって、これらの型材を後加工する必要がない。したがって、これら第１フレーム１と第２のフレーム２とを一層簡単に接続することができる。 Further, in the first frame 1, the groove 101 of the mold material is the first opening 1 b as it is, and the through hole 203 of the mold material is the second opening 2 b as it is in the second frame 2. Then, by rotating the mounting screw 7 from the peripheral surface 4c side of the main body 4, the first insertion portion 5 is locked in the groove 101 of the mold material that becomes the first opening 1b, and the second insertion portion 6 is locked in the through hole 203 of the mold material which becomes the second opening 2b, and therefore it is necessary to post-process these mold materials when connecting the first frame 1 and the second frame 2 to each other. Absent. Therefore, the first frame 1 and the second frame 2 can be more easily connected.

また、本体４は、第２フレームと同一の型材からなることから、その型材を切断することで、本体４が容易に製作される。そして、本体４は、他方の端面４ｂが、第２フレーム２の端面２ａと一致するように突き合わされることから、この本体４と第２フレーム２との一体感が増す。特に、図示実施の形態においては、第２フレーム２の溝２０３が、本体４の溝部４ｅと連続することとなり、この本体４の溝部４ｅを、第２フレーム２の溝２０３の延長として、利用することができる。 Further, since the main body 4 is made of the same mold material as the second frame, the main body 4 can be easily manufactured by cutting the mold material. Since the main body 4 is abutted so that the other end face 4b coincides with the end face 2a of the second frame 2, the sense of unity between the main body 4 and the second frame 2 is increased. In particular, in the illustrated embodiment, the groove 203 of the second frame 2 is continuous with the groove 4 e of the main body 4, and the groove 4 e of the main body 4 is used as an extension of the groove 203 of the second frame 2. be able to.

なお、本発明は、上述した実施の形態に限定されるわけではなく、その他種々の変更が可能である。例えば、図９ないし図１１に示すように、第２挿入部６のみならず、第１挿入部５もまた、互いに分割された分割部から構成されてもよい。すなわち、この実施の形態においては、第１挿入部５は、互いに分割された第１分割部５０１、５０１から構成され、そして、第２挿入部６は、互いに分割された第２分割部６０１、６０１から構成される。そこで、接続具３は、第１分割部５０１と第２分割部６０１とを有する、一方および他方の分割部材１５、１５を備える。そして、一方の分割部材１５は、取付ネジ１６が螺合する貫通状の雌ねじ部１５ａを有する。また、他方の分割部材１５は、雌ねじ部１５ａに螺合した取付ネジ１６の先端が当接する当接部１５ｂを有する。そして、これら分割部材１５、１５は、本体４の通孔部４ｄに挿入される。そこで、本体４の周面４ｃ側からの、取付ネジ１６の回動操作（ねじ込み）により、その取付ネジ１６の先端が当接部１５ｂを押して、一方および他方の分割部材１５、１５が互いに離れるように相対移動する。この相対移動により、第１分割部５０１、５０１が、第１の開口部１ｂとしての第１フレーム１の溝１０１の内面（図示実施の形態においては、突条部１０２、１０２の対向面）を押圧するとともに、第２分割部６０１、６０１が、第２の開口部２ｂとしての第２フレーム２の通孔２０３の内面を押圧する。こうして、第１分割部５０１、５０１からなる第１挿入部５は、第１フレーム１の溝１０１に係止され、第２分割部６０１、６０１からなる第２挿入部６は、第２フレーム２の通孔２０３に係止される。このように、本体４に設けられた一本の取付ネジ１６を、本体４の周面４ｃ側から回動操作する（ねじ込む）ことで、第１挿入部５が第１フレーム１の溝１０１に係止されるとともに、第２挿入部６が第２フレーム２の通孔２０３に係止されて、これら第１フレーム１と第２のフレーム２とが簡単に接続される。また、反対に、第１フレーム１と第２フレーム２とを分離する場合は、取付ネジ１６を、前記と逆方向に回動操作する（緩める）ことで、第１挿入部５の、溝１０１への係止と、第２挿入部６の、通孔２０３への係止が解除される。 In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, as shown in FIGS. 9 to 11, not only the second insertion portion 6 but also the first insertion portion 5 may be composed of divided portions that are divided from each other. That is, in this embodiment, the first insertion part 5 is composed of first division parts 501 and 501 that are divided from each other, and the second insertion part 6 is divided into second division parts 601 and 601 that are divided from each other. 601. Therefore, the connector 3 includes one and the other divided members 15 and 15 each having a first divided portion 501 and a second divided portion 601. One split member 15 has a penetrating female screw portion 15a to which the mounting screw 16 is screwed. The other split member 15 has a contact portion 15b with which the tip of the mounting screw 16 screwed into the female screw portion 15a contacts. The divided members 15 and 15 are inserted into the through hole 4 d of the main body 4. Therefore, by turning operation (screwing) of the mounting screw 16 from the peripheral surface 4c side of the main body 4, the tip of the mounting screw 16 pushes the contact portion 15b, and the one and the other divided members 15, 15 are separated from each other. Move relative. By this relative movement, the first divided portions 501 and 501 move the inner surface of the groove 101 of the first frame 1 as the first opening 1b (in the illustrated embodiment, the opposing surface of the protrusions 102 and 102). While pressing, the 2nd division parts 601 and 601 press the inner surface of the through-hole 203 of the 2nd frame 2 as the 2nd opening part 2b. Thus, the first insertion portion 5 including the first divided portions 501 and 501 is locked in the groove 101 of the first frame 1, and the second insertion portion 6 including the second divided portions 601 and 601 is connected to the second frame 2. The through hole 203 is locked. Thus, the first insertion portion 5 is inserted into the groove 101 of the first frame 1 by rotating (screwing) one mounting screw 16 provided on the main body 4 from the peripheral surface 4 c side of the main body 4. In addition to being locked, the second insertion portion 6 is locked to the through-hole 203 of the second frame 2 so that the first frame 1 and the second frame 2 are easily connected. On the other hand, when the first frame 1 and the second frame 2 are separated, the mounting screw 16 is rotated (loosened) in the opposite direction to the groove 101 of the first insertion portion 5. And the locking of the second insertion portion 6 to the through hole 203 is released.

また、第１フレーム１と第２フレーム２とは、図示実施の形態に示すような断面形状に限定されないことは当然であり、また、両者は、同一の型材からならなくとも、別の型材、すなわち、断面形状が異なる型材からなっていてもよい。さらには、第１フレーム１と第２フレーム２とは、型材でなくともよい。 In addition, the first frame 1 and the second frame 2 are naturally not limited to the cross-sectional shape as shown in the illustrated embodiment, and both are different from each other, even if they are not made of the same mold material. That is, it may be made of molds having different cross-sectional shapes. Furthermore, the first frame 1 and the second frame 2 need not be mold materials.

また、第２フレーム２における第２の開口部２ｂは、図示実施の形態に示すような通孔でなくてもよく、例えば、溝状のものであっても構わない。 Moreover, the 2nd opening part 2b in the 2nd flame | frame 2 may not be a through-hole as shown in illustration embodiment, for example, may be a groove-shaped thing.

また、本体４は、第２フレーム２と、同一断面形状でなくとも、異なる断面形状であってもよい。そして、この本体４は、必ずしも型材からならなくとも、切削等によって形成されてもよい。 Further, the main body 4 may have a different cross-sectional shape from the second frame 2 even if it does not have the same cross-sectional shape. The main body 4 may be formed by cutting or the like, although not necessarily made of a mold material.

また、第１ガイド部材１０は、取付ネジ７と別体でなくとも、一体に設けられてもよい（すなわち、取付ネジ７が第１ガイド部材１０の機能を兼用しても構わない。）。そして、ナット９ｈにおいても、第２部材９とは別に設けられなくとも、例えば、第２部材９の第２の孔９ｅにねじを切るようにして設けられてもよい。 Further, the first guide member 10 may be provided integrally with the attachment screw 7 (ie, the attachment screw 7 may also serve as the function of the first guide member 10). Further, the nut 9h may be provided so as to be screwed into the second hole 9e of the second member 9 without being provided separately from the second member 9, for example.

また、第２部材９における第４の被押圧部９ａは、一対の第２部材９、９のそれぞれに設けられなくとも、一方のみに設けられてもよい。そして、この場合には、第２ガイド部材１１には、第４の被押圧部９ａと対応するように、突部１１ｃの片側のみに傾斜面となった第４の押圧部１１ｂが設けられる。 Further, the fourth pressed portion 9a in the second member 9 may be provided only in one of the pair of second members 9 and 9 without being provided in each of the pair of second members 9 and 9. In this case, the second guide member 11 is provided with a fourth pressing portion 11b having an inclined surface only on one side of the protruding portion 11c so as to correspond to the fourth pressed portion 9a.
