Description
この出願の発明は、部材同士を連結具を介してネジ連結する部材連結構造、およびそれに用いられる連結具に関するものである。 The invention of this application relates to a member connection structure in which members are screw-connected to each other via a connector, and a connector used therefor.
従来、フレームやレール等の部材同士を連結する構造として、一方の部材および他方の部材それぞれに連結孔を設け、それら連結孔をちょうど一致させた状態で連結ネジをねじ込むようにした構造がしばしば用いられている。 Conventionally, as a structure for connecting members such as a frame and a rail, a structure in which a connection hole is provided in each of the one member and the other member, and the connection screw is screwed in a state where the connection holes are just matched is often used. It has been.
また、一方の部材に設けた連結孔に留め具を挿入し、この留め具が有するネジ導入空間の入口孔と他方の部材に設けた連結孔とを一致させた状態で連結ネジをねじ込むようにした構造も知られている（特許文献１参照）。
しかしながら、上記のとおりに連結ネジを部材の連結孔に直接螺入させる従来の部材連結構造では、たとえば図９に例示したように、連結孔（ア）が互いにちょうど一致しておらず、僅かにずれた状態、つまり偏心して重なっている状態では連結ネジをねじ込めないため、部材（イ）位置の微調整を行って連結孔（ア）を一致させたまま、連結ネジの螺入作業を行う必要があり、微調整・状態維持・螺入という効率の悪い連結作業となっていた。 However, in the conventional member connection structure in which the connection screw is screwed directly into the connection hole of the member as described above, for example, as illustrated in FIG. Since the connecting screw cannot be screwed in a deviated state, that is, in an eccentric and overlapping state, the connecting screw is screwed in with the connecting hole (a) aligned by finely adjusting the position of the member (a). It was necessary, and it was an inefficient connection work of fine adjustment, state maintenance, and screwing.
また、上記特許文献１に記載の構造においても、留め具を用いてはいるものの、やはり互いに一致した連結孔（ア）への連結ネジ螺入作業が必要であることには変わらない。 Further, in the structure described in Patent Document 1, although a fastener is used, it is still necessary to perform a connecting screw screwing operation into the connecting holes (a) that are coincident with each other.
そこで、以上のとおりの事情に鑑み、この出願の発明は、各部材の連結孔が互いに偏心して重なっている状態であっても連結ネジをねじ込ませることができ、且つその連結ネジをねじ込むだけで連結孔が一致して同心状態となり、部材同士をしっかりと密着させて連結することのできる、部材連結構造および連結具を提供することを課題としている。 Therefore, in view of the circumstances as described above, the invention of this application is capable of screwing the connection screw even when the connection holes of the respective members are decentered and overlapping, and only screwing the connection screw.

図１（ａ）〜（ｅ）は、各々、この出願の発明の部材連結構造において用いられる連結具の一実施形態を示したものである。 1 (a) to 1 (e) each show an embodiment of a connecting tool used in the member connecting structure of the invention of this application.
この図１の一実施形態では、連結具（１）は、基部（１１）と２つの連結孔挿入部（１２）とを有しており、たとえばそれらが一体成形された樹脂製のものとなっている。 In the embodiment of FIG. 1, the connector (1) has a base (11) and two connecting hole insertion portions (12), and is made of resin in which they are integrally molded, for example. ing.
基部（１１）は、細帯板状のものとなっており、板長手方向に沿って互いに離間した２つのネジ挿入口（１１１）を有している。 The base portion (11) is in the form of a narrow strip, and has two screw insertion openings (111) spaced apart from each other along the longitudinal direction of the plate.
各連結孔挿入部（１２）は、基部（１１）の裏面から互いに離間して上記各ネジ挿入口（１１１）と略一致した位置にて突出したものとなっており、基部（１１）裏面と接した根元側から先端側にわたって、基部（１１）のネジ挿入口（１１１）と連通したネジ螺入孔（１２１）を有しているとともに、同じく根元側から先端側にわたって全体が十字状に分割された形状を有している。そしてさらに、その外周面にて互いに反対方向に且つ基部（１１）の長手方向に脹らんだ一対の膨出部（１２２ａ）（１２２ｂ）を有してもいる。この連結孔挿入部（１２）は、一対の膨出部（１２２ａ）（１２２ｂ）の存在により、先端側から見た輪郭形状が膨出部（１２２ａ）（１２２ｂ）を結ぶ径が長く、膨出部（１２２ａ）（１２２ｂ）のない面を結ぶ径が短い略楕円形状となっている（図１（ｃ）参照）。 Each connection hole insertion portion (12) is spaced apart from the back surface of the base portion (11) and protrudes at a position substantially coincident with each of the screw insertion ports (111). It has a screw insertion hole (121) that communicates with the screw insertion port (111) of the base (11) from the contacted root side to the tip side, and is also divided into a cross shape from the root side to the tip side. Has the shape. Furthermore, it has a pair of bulging parts (122a) (122b) which swelled in directions opposite to each other on the outer peripheral surface and in the longitudinal direction of the base part (11) . Due to the presence of the pair of bulging portions (122a) and (122b), the connecting hole insertion portion (12) has a long diameter connecting the bulging portions (122a) and (122b) as seen from the distal end side. It has a substantially elliptical shape with a short diameter connecting the surfaces without the portions (122a) and (122b) (see FIG. 1C).
図２、図３（ａ）（ｂ）および図４（ａ）（ｂ）は、各々、この出願の発明の連結構造の一実施形態を示したものであり、縦フレーム部材（２）の側面（２１）に横板部材（３）の裏面から突出した連結片（３１）を当接させて一対の縦フレーム部材（２）間に横板部材（３）を掛け渡し、縦フレーム部材（２）の側面（２１）および横板部材（３）の連結片（３１）に設けられた複数の連結孔（２１１）（３１１）に対する連結ネジ（４）のねじ込みによって、横板部材（３）が縦フレーム部材（２）に連結される。 2, FIG. 3 (a) (b) and FIG. 4 (a) (b) each show one embodiment of the connecting structure of the invention of this application, and the side surface of the vertical frame member (2). The connecting piece (31) protruding from the back surface of the horizontal plate member (3) is brought into contact with (21), and the horizontal plate member (3) is stretched between the pair of vertical frame members (2), whereby the vertical frame member (2 ) And the lateral plate member (3) by screwing the coupling screw (4) into the coupling holes (211) (311) provided in the coupling piece (31) of the lateral plate member (3). It is connected to the vertical frame member (2).
かかる場合において、図２に例示したように、たとえば連結片（３１）における連結孔（３１１)の穴開け加工時に位置寸法Ｐのずれが生じたりすると、連結片（３１）を縦フレーム部材（２）の側面（２１）に合わせた際に連結孔（３１１）および連結孔（２１１）の位置が一致しなくなってしまう。この状態で連結ネジ（４）を直接ねじ込むことは困難である。 In such a case, as illustrated in FIG. 2, for example, if a displacement of the position dimension P occurs during the drilling of the connection hole (311) in the connection piece (31), the connection piece (31) is moved to the vertical frame member (2 ), The positions of the connecting hole (311) and the connecting hole (211) do not coincide with each other. In this state, it is difficult to screw the connecting screw (4) directly.
そこで、上述した連結具（１）を偏心状態の連結孔（３１１）および連結孔（２１１）に対して取り付け、連結ネジ（４）を連結具（１）にねじ込むようにする。 Therefore, the connecting tool (1) is attached to the connecting hole (311) and the connecting hole (211) in an eccentric state, and the connecting screw (4) is screwed into the connecting tool (1).
より具体的には、まず、連結具（１）の連結孔挿入部（１２）を連結孔（３１１）から連結孔（２１１）へ挿入するのであるが、互いに偏心して重なっている連結孔（３１１）および連結孔（２１１）の重なり代は略楕円状となっており、この略楕円状の重なり代に対して連結孔挿入部（１２）を挿入させる必要がある。このとき、連結孔挿入部（１２）は上述したとおりに一対の膨出部（１２２ａ）（１２２ｂ）の存在によって先端側から見た形状が略楕円状となっているので、略楕円状重なり代に互いの長手方向を一致させてちょうど挿入できるのである。 More specifically, the connecting hole insertion portion (12) of the connecting tool (1) is first inserted into the connecting hole (211) from the connecting hole (311). ) And the coupling hole (211) are substantially elliptical, and it is necessary to insert the coupling hole insertion portion (12) into the substantially elliptical overlapping margin. At this time, the connecting hole insertion portion (12) has a substantially elliptical shape as viewed from the front end side due to the presence of the pair of bulging portions (122a) and (122b) as described above. They can be inserted just in the same longitudinal direction.
なお、連結孔挿入部（１２）は全体が十字状に分割され、その分割部分がある程度の幅を持った溝状となっているため、図５に例示したように略楕円状重なり代Ｅの長手方向Ｌが若干狭くても、連結孔挿入部（１２）の長手方向Ｌ径を溝部分を狭めて調整し、挿入させることができ、また図６に例示したように略楕円状重なり代Ｅの短手方向Ｓが若干狭くても、連結孔挿入部（１２）の短手方向Ｓ径を溝部分を狭めて調整し、挿入させることができる。言い換えると、連結孔挿入部（１２）全体をその中心に向かってたわませることで、略楕円状重なり代Ｅに挿入できるのである。 The connecting hole insertion portion (12) is divided into a cross shape as a whole, and the divided portion has a groove shape with a certain width. Therefore, as illustrated in FIG. Even if the longitudinal direction L is slightly narrow, it is possible to adjust and insert the longitudinal diameter L of the connecting hole insertion portion (12) by narrowing the groove portion. Also, as illustrated in FIG. Even if the short direction S is slightly narrow, the short direction S diameter of the connecting hole insertion portion (12) can be adjusted by narrowing the groove portion and inserted. In other words, the entire connecting hole insertion portion (12) can be inserted into the substantially elliptical overlap margin E by bending toward the center.
図３（ａ）および図４（ａ）は、各々、以上のように連結孔挿入部（１２）を連結孔（３１１）および連結孔（２１１）に挿入させた状態を例示しており、図３（ａ）は縦方向断面図、図４（ｂ）は横方向断面図となっている。本実施形態では、連結孔挿入部（１２）は基部（１１）に一対備えられており、縦フレーム部材（２）の側面（２１）において縦方向に並んで配設された複数の連結孔（２１１）のうちの２つの連結孔（２１１）にそれぞれ挿入される。この挿入により、連結具（１）自体が連結孔（３１１）および連結孔（２１１）に取り付けられることになる。 3 (a) and 4 (a) illustrate the state in which the connecting hole insertion portion (12) is inserted into the connecting hole (311) and the connecting hole (211) as described above. 3 (a) is a longitudinal sectional view, and FIG. 4 (b) is a transverse sectional view. In the present embodiment, a pair of connection hole insertion portions (12) are provided on the base portion (11), and a plurality of connection holes (lined in the vertical direction on the side surface (21) of the vertical frame member (2) ( 211) are inserted into the two connecting holes (211), respectively. By this insertion, the connector (1) itself is attached to the connection hole (311) and the connection hole (211).
連結孔挿入部（１２）は複数設けられているので、連結ネジ（４）のねじ込み時に基部（１１）が廻ってしまうのを防ぐことができ、また連結後の曲げモーメントに対する耐性をより大きく維持することができる。 The connecting hole inserting portion (12) is provided multiple, it is possible to prevent the base portion when screwing the connecting screw (4) (11) resulting in traveling around, also greater resistance to bending moment after connecting Can be maintained.
続いて、連結ネジ（４）を、基部（１１）のネジ挿入口（１１１）から連結孔挿入部（１２）のネジ螺入孔（１２１）にねじ込む。このねじ込みにより、図３（ｂ）および図４（ｂ）に例示したように、ネジ螺入孔（１２１）が押し広げられて連結孔挿入部（１２）全体が十字状分割部分にて外方に広がることになる。これにより、横板部材（３）の連結片（３１）が縦フレーム部材（２）の側面（２１）に引き寄せられるだけでなく、連結孔（２１１）に対して偏心状態の連結孔（３１１）が引き寄せられて互いに同心状態となり（図４（ｂ）参照）、横板部材（３）全体も縦フレーム部材（２）に引き寄せられて、互いに隙間なく当接し、しっかりとした連結が実現される。 Subsequently, the connecting screw (4) is screwed into the screw screw hole (121) of the connecting hole insertion portion (12) from the screw insertion port (111) of the base portion (11). As shown in FIG. 3B and FIG. 4B, this screwing causes the screw screw hole 121 to be widened so that the entire connecting hole insertion portion 12 is outward at the cross-shaped divided portion. Will spread. Thereby, not only the connection piece (31) of the horizontal plate member (3) is attracted to the side surface (21) of the vertical frame member (2) but also the connection hole (311) in an eccentric state with respect to the connection hole (211). Are drawn to be concentric with each other (see FIG. 4 (b)), and the entire horizontal plate member (3) is also drawn to the vertical frame member (2) to contact each other without any gaps, thereby realizing a firm connection. .
このとき、縦フレーム部材（２）内において外方に広がった連結孔挿入部（１２）の膨出部（１２２ａ）（１２２ｂ）は、連結孔（３１１）の裏側に引っ掛るようになるので、よりしっかりとした連結が実現されることとなる。 At this time, the connecting hole inserting portion spread outward in the longitudinal frame member (2) within the bulging part of (12) (122a) (122b), since become caught on the back side of the connecting hole (311) A more secure connection will be realized.
なお、基部（１１）におけるネジ挿入口（１１１）部分の肉厚は薄くすることが好ましく（図１（ｄ）参照）、これにより、螺入時の連結ネジ（４）がねじ込み方向とは反対方向からの抵抗により鉛直方向に向くため、ゆがめてねじ込んでしまうことがなくなり、まっすぐのねじ込みによる両部材のさらにしっかりとした引き寄せが可能となる。 In addition, it is preferable to make thin the thickness of the screw insertion opening (111) portion in the base (11) (see FIG. 1 (d)), so that the connecting screw (4) at the time of screwing is opposite to the screwing direction. Since it is oriented in the vertical direction due to the resistance from the direction, it will not be distorted and screwed in, and both members can be pulled more firmly by straight screwing.
また、連結具（１）の連結孔挿入部（１２）は、たとえば、図７（ａ）に例示したようにその外周面の横断面形状が曲線円状のものとしてもよいが、図７（ｂ）（ｃ）に例示したように弦状あるいは逆円弧状のものとしてもよい。より具体的には、図７（ｂ）（ｃ）では、十字状分割された外周面の４つ角部分それぞれの横断面形状が弦状あるいは逆円弧状（逆への字状とも呼べる）となっている。このような弦状あるいは逆円弧状とすることで、連結孔（３１１）（２１１）に挿入させた際に連結孔（３１１）（２１１）の縁との間に遊び空間が生まれることになり、連結ネジ（４）の螺入により外方に広がっていっても連結孔（３１１）（２１１）の縁にこすれ難くなり、また連結ネジ（４）が途中で止まり難くもなる。なお、図１では、逆円弧状の場合の連結孔挿入部（１２）のより詳細な形状を図示している。図５および図６における連結孔挿入部（１２）は弦状のものとなっている。 In addition, the connection hole insertion portion (12) of the connection tool (1) may have, for example, a circular cross-sectional shape on the outer peripheral surface as illustrated in FIG. b) As illustrated in (c), it may have a string shape or a reverse arc shape. More specifically, in FIGS. 7B and 7C, the cross-sectional shape of each of the four corners of the outer peripheral surface divided in a cross shape is a chord shape or a reverse arc shape (also called a reverse character shape). It has become. By having such a string shape or reverse arc shape, a play space is created between the edges of the connection holes (311) (211) when inserted into the connection holes (311) (211). Even if the connecting screw (4) is spread outward by screwing, it is difficult to rub against the edges of the connecting holes (311) and (211), and the connecting screw (4) is difficult to stop halfway. In addition, in FIG. 1, the more detailed shape of the connection hole insertion part (12) in the case of a reverse arc shape is illustrated. The connection hole insertion part (12) in FIG. 5 and FIG.
連結孔挿入部（１２）の十字状分割部分における溝幅については、短手方向にある溝幅の寸法Ｎを長手方向にある溝幅の寸法Ｍよりも長いものとする（図１（ｃ）参照）。これにより、短手方向のたわみ量が少なく、連結孔（３１１）を連結孔（２１１）へ引き付ける力が大きくなる。具体的寸法としては、たとえば長手方向溝幅Ｍ＝１．０ｍｍ、短手方向溝幅Ｎ＝１．５ｍｍなどを考慮できる。 The groove width in the cross-shaped wedges of the connecting hole inserting portion (12) shall be the dimension N of the groove width in the lateral direction are longer than the dimension M of the groove width in the longitudinal direction (FIG. 1 (c See)) . Thereby, there is little deflection amount of a transversal direction, and the force which attracts a connecting hole (311) to a connecting hole (211) becomes large. As specific dimensions, for example, a longitudinal groove width M = 1.0 mm and a short-side groove width N = 1.5 mm can be considered.
そして、以上のとおりに縦フレーム部材（２）および横板部材（３）を連結させて組み合わせることで、たとえば図８に例示したようなアルミフレーム型キッチンキャビネットなどのフレーム組立型の筐体を構成することができる。この場合、たとえば、横板部材（３）は、引出しや棚板等の支持レール部材としたり、支持レールを取り付けることのできる部材としたりすることができる。もちろん、上述したように連結具（１）および連結ネジ（４）により連結作業は簡単に行うことができるので、また連結具（１）も連結ネジ（４）のねじ込み・ねじ外しだけで着脱自在であるので、横板部材（３）を縦フレーム部材（２）に対して所望の高さ位置に容易に変更することが可能である。 Then, by assembling and combining the vertical frame member (2) and the horizontal plate member (3) as described above, a frame assembly type housing such as an aluminum frame type kitchen cabinet as illustrated in FIG. 8 is configured. can do. In this case, for example, the horizontal plate member (3) can be a support rail member such as a drawer or a shelf board, or a member to which the support rail can be attached. Of course, as described above, since the connecting work can be easily performed by the connecting tool (1) and the connecting screw (4), the connecting tool (1) is also detachable only by screwing / unscrewing the connecting screw (4). Therefore, it is possible to easily change the horizontal plate member (3) to a desired height position with respect to the vertical frame member (2).
