Description
本発明は２部材を連結するために使用される連結部材に関し、より詳しくは、たとえばドアを開口枠に開閉可能に設置するためにドアと開口枠（縦枠）とに丁番を取り付ける際にネジと共に使用される連結部材に関する。本発明は、さらに、この連結部材を用いて得られる固定構造に関する。 The present invention relates to a connecting member used for connecting two members, and more specifically, for example, when attaching a hinge to a door and an opening frame (vertical frame) in order to install the door in the opening frame so as to be openable and closable. Regarding connecting members used with screws. The present invention further relates to a fixed structure obtained by using this connecting member.
周知のように、丁番は軸に対してそれぞれ回転可能に設けられる一対の取付片を有し、一方の取付片をドアの閉じ側木口端近くにネジで固定し、他方の取付片を閉じ側の縦枠にネジで固定することにより、ドアを開閉可能に設置する。このときに、ネジを丁番越しにドアおよび縦枠に単にねじ込んで丁番を取り付けることもあるが、ドアや縦枠が主としてＭＤＦなどの木質材で形成される場合、主として金属で形成される丁番との材質の相違による比重差が大きくなり、単にネジをねじ込むだけでは十分な固定強度が得られないことがある。また、縦枠に対しては丁番を介してネジを縦枠の厚さ方向にねじ込んで固定することになるため、十分に長いネジを使用することができず、固定強度が不足しがちになる。 As is well known, the hinge has a pair of mounting pieces that are rotatably provided with respect to the shaft, one mounting piece is screwed near the end of the door closing side and the other mounting piece is closed. The door can be opened and closed by fixing it to the vertical frame on the side with screws. At this time, the hinge may be attached by simply screwing the screw into the door and the vertical frame through the hinge, but when the door and the vertical frame are mainly formed of wood material such as MDF, they are mainly formed of metal. Due to the difference in material from the hinge, the difference in specific gravity becomes large, and it may not be possible to obtain sufficient fixing strength simply by screwing in the screw. In addition, since screws are screwed into the vertical frame in the thickness direction of the vertical frame via hinges to fix it, it is not possible to use sufficiently long screws, and the fixing strength tends to be insufficient. Become.
このような場合に、縦枠を厚さ方向に貫通する貫通穴を形成し、この貫通穴の丁番取付側とは反対側の開口からナット状の連結部材を挿入して取り付け、この連結部材の雌ネジに、丁番を介して挿入されたネジを螺合させることにより、強固な連結を確保することが行われている（特許文献１）。 In such a case, a through hole that penetrates the vertical frame in the thickness direction is formed, and a nut-shaped connecting member is inserted and attached from the opening on the side opposite to the hinge mounting side of the through hole, and this connecting member is attached. By screwing a screw inserted via a hinge into the female screw of No. 1 to ensure a strong connection (Patent Document 1).
しかしながら、このような連結部材を用いて丁番を縦枠に固定するには、ネジを連結部材の雌ネジに螺合させるために重い電動ドライバーなどの工具を用いて作業する必要があり、この作業を、一つの丁番について複数個所（たとえば特許文献１の図２記載の実施態様によればドアに対する固定と縦枠に対する固定とで各４箇所）で行い、さらに、ドア／縦枠の高さ方向において異なる２箇所またはそれ以上の箇所で繰り返して行わなければならず、作業手間と時間を要していた。近年では、大工技能者の減少に伴い、作業に不慣れな若年入職者や女性が作業する機会も増加しており、電動ドライバーなどの工具を用いずに丁番固定作業を行うことができるようにすることが望まれている。 However, in order to fix the hinge to the vertical frame using such a connecting member, it is necessary to work with a tool such as a heavy electric screwdriver in order to screw the screw into the female screw of the connecting member. The work is performed at a plurality of places (for example, four places each for fixing to the door and fixing to the vertical frame according to the embodiment shown in FIG. 2 of Patent Document 1) for one hinge, and further, the height of the door / vertical frame is further increased. It had to be repeated at two or more different places in the hinge direction, which required labor and time. In recent years, as the number of carpenter technicians has decreased, the opportunities for young employees and women who are unfamiliar with the work have increased, so that hinge fixing work can be performed without using tools such as electric screwdrivers. It is desired to do.
したがって、本発明が解決しようとする課題は、電動ドライバーなどの工具を用いずに丁番をドアや縦枠に取り付けるなどの２部材連結作業を簡単に行うことができる連結部材を提供すると共に、この連結部材を用いて一部材を他部材に連結固定してなる固定構造を提供することである。 Therefore, the problem to be solved by the present invention is to provide a connecting member capable of easily performing a two-member connecting work such as attaching a hinge to a door or a vertical frame without using a tool such as an electric screwdriver.

A screw inserted from a screw mounting hole of a member into a pilot hole for a screw is locked to the screw engaging portion of the connecting member.
本願の請求項１に係る発明によれば、一部材を他部材に取り付けようとする際に、ネジを連結部材の第一端部から第二端部に向けてネジ挿入空間内に挿入して連結部材のネジ係合部に入り込もうとすると、該ネジ係合部が弾性変形可能であって、且つ、その突出先端同士が、ネジのネジ山を含めたネジ外径より小さい直径の円を描くように形成されていることから、ネジ山がネジ係合部を押し拡げながら前進させていくことができる。この作業は、従来のように電動ドライバーなどの工具を用いてネジを回す必要がなく、手やハンマーなどでネジを直線的に押し込むだけで良いので、作業に不慣れな若年入職者や女性でも簡単に連結作業を行うことができる。 According to the invention according to claim 1 of the present application, when one member is to be attached to another member, a screw is inserted into the screw insertion space from the first end portion to the second end portion of the connecting member. When attempting to enter the screw engaging portion of the connecting member, the screw engaging portion is elastically deformable, and the protruding tips form a circle with a diameter smaller than the outer diameter of the screw including the screw thread. Since it is formed in this way, the screw thread can be advanced while expanding the screw engaging portion. This work is easy even for young employees and women who are unfamiliar with the work, because it is not necessary to turn the screw with a tool such as an electric screwdriver as in the past, just push the screw straight with a hand or a hammer. Can be connected to.
しかも、上記のようにして一部材が他部材に取り付けられた状態においては、ネジがネジ係合部に係合されているので、ネジを引き抜こうとしてもこの係合によって引き抜くことができない。したがって、強固な固定構造を維持することができる。この状態から解体するには、従来と同様に、電動ドライバーなどの工具を用いてネジを反時計回りに回転させれば良い。 Moreover, in the state where one member is attached to the other member as described above, since the screw is engaged with the screw engaging portion, even if the screw is to be pulled out, it cannot be pulled out by this engagement. Therefore, a strong fixed structure can be maintained. To disassemble from this state, the screw may be rotated counterclockwise using a tool such as an electric screwdriver as in the conventional case.
本願の請求項２に係る発明によれば、内側円筒部の前記第二の軸方向領域には前記第二端部に開口するスリットが形成されると共に、該第二の軸方向領域において内側円筒部の外面と外側円筒部の内面との間に隙間が形成されているので、ネジがネジ係合部を通過するときに、ネジ係合部が弾性変形により拡径することを容易にし、スムーズなネジ挿入作業を行うことができる。 According to the invention according to claim 2 of the present application, a slit opening at the second end portion is formed in the second axial region of the inner cylindrical portion, and the inner cylinder is formed in the second axial region. Since a gap is formed between the outer surface of the portion and the inner surface of the outer cylindrical portion, it is easy for the screw engaging portion to expand in diameter due to elastic deformation when the screw passes through the screw engaging portion, and the diameter is smooth. Can perform various screw insertion work.
本願の請求項３に係る発明によれば、別部材として形成された内側円筒部と外側円筒部をネジの螺合によって結合一体化されるので、各円筒部を所要の形状に成形することが容易であり、且つ、ネジの螺合によって強固に一体化された連結部材とすることができる。 According to the invention according to claim 3 of the present application, since the inner cylindrical portion and the outer cylindrical portion formed as separate members are connected and integrated by screwing a screw, each cylindrical portion can be formed into a required shape. It is easy and can be a connecting member that is firmly integrated by screwing a screw.
本願の請求項４に係る発明によれば、他部材に形成した連結部材用下穴に連結部材を収容する際に、連結部材用下穴の開口に形成した拡径部に鍔部を収容した状態で、連結部材用下穴の筒状部の内面に突起を圧接させることができるので、位置決めが容易であり、また、不慮の抜け落ちを防ぐことができる。 According to the invention according to claim 4 of the present application, when the connecting member is housed in the pilot hole for the connecting member formed in the other member, the collar portion is housed in the enlarged diameter portion formed in the opening of the pilot hole for the connecting member. In this state, the protrusion can be pressed against the inner surface of the tubular portion of the pilot hole for the connecting member, so that positioning is easy and accidental removal can be prevented.
本願の請求項５記載の発明によれば、ネジ係合部として、ネジ挿入空間に向けてネジの挿入方向に傾斜するように対向して設けられる少なくとも一対の突片を雌ネジに代えて用いることができる。ネジ係合部として少なくとも一対の突片を採用した場合、雌ネジに比べてネジ保持力は若干低下するが、ネジを押し込んだときに突片自体が弾性変形してネジの通過を許容するので、作業に要する力が少なくて済む利点がある。 According to the invention according to claim 5 of the present application, at least a pair of projecting pieces provided so as to be inclined in the screw insertion direction toward the screw insertion space are used instead of the female screw as the screw engaging portion. be able to. When at least a pair of projecting pieces are used as the screw engaging part, the screw holding force is slightly lower than that of a female screw, but when the screw is pushed in, the projecting pieces themselves elastically deform to allow the screw to pass through. There is an advantage that less force is required for work.
本願の請求項６記載の発明によれば、この連結部材をネジと共に使用して一部材を他部材に取り付けて得られる固定構造が提供され、取り付けの際に、従来のように電動ドライバーなどの工具を用いてネジを回す必要がなく、ネジを直線的に押し込むだけで良いので、作業に不慣れな若年入職者や女性でも簡単に連結作業を行うことができる。 According to the invention of claim 6 of the present application, a fixing structure obtained by attaching one member to another member by using this connecting member together with a screw is provided, and at the time of attachment, an electric screwdriver or the like is provided as in the conventional case. There is no need to turn the screw with a tool, just push the screw in a straight line, so even young employees and women who are unfamiliar with the work can easily perform the connection work.
以下に実施例を挙げて本発明について説明する。 The present invention will be described below with reference to examples.
本発明の好適な一実施形態（実施例）について、図１〜図５を参照して以下に詳述する。この実施例では、ドア４０の閉じ側木口端４１に、丁番５０のネジ取付穴５１に合致させた箇所からネジ用下穴４２，４２および連結部材用下穴４３，４３をあらかじめ形成しておき、該木口端４１に開口する連結部材用下穴４３，４３に各々篏合配置した連結部材１０，１０にドア木口端４１の外側から丁番５０越しにネジ（またはボルト。以下も同じ。）６０を係合させることにより、丁番５０をドア４０に固定している（図５）。各ネジ用下穴４２は、ネジ６０の軸径と略同一またはそれより若干大きい内径を有し、ネジ６０の軸長より十分に大きい長さを有する。各連結部材用下穴４３は、各ネジ用下穴４２がドア木口端４１で開口する部分を連結部材１０の外形に応じた形状および寸法を有するように拡径して形成される。 A preferred embodiment (Example) of the present invention will be described in detail below with reference to FIGS. 1 to 5. In this embodiment, the screw pilot holes 42, 42 and the connecting member pilot holes 43, 43 are preliminarily formed at the closing end of the door 40 from the portion matching the screw mounting hole 51 of the hinge 50. Screws (or bolts; the same shall apply hereinafter) from the outside of the door end 41 to the connecting members 10 and 10 which are arranged in the pilot holes 43 and 43 for the connecting member which are opened at the end 41 of the door. ) 60 is engaged to fix the hinge 50 to the door 40 (FIG. 5). Each screw pilot hole 42 has an inner diameter substantially equal to or slightly larger than the shaft diameter of the screw 60, and has a length sufficiently larger than the shaft length of the screw 60. The pilot hole 43 for each connecting member is formed by expanding the portion of the pilot hole 42 for a screw that opens at the end 41 of the door end so as to have a shape and dimensions corresponding to the outer shape of the connecting member 10.
図５に示す丁番固定構造を得るためにネジ６０と共に用いられる連結部材１０は、一例として、図１〜図４に示す形状を有する。この連結部材１０は、内側円筒部２０と外側円筒部３０とからなり、ネジ６０の軸長より十分に短い軸長を有する。内側円筒部２０と外側円筒部３０は、いずれも、ある程度の弾性変形を許容すると共に、元の形状に復帰しようとする形状復元力を保持することができる材料で形成され、たとえば、硬質ＰＶＣ、アクリル樹脂、ナイロン樹脂、フェノール樹脂、ユリア樹脂、メラミン樹脂、ポリテトラフルオロエチレン樹脂、ポリプロピレン樹脂などの合成樹脂材料や、アルミ、亜鉛などの金属材料から形成することができる。 The connecting member 10 used together with the screw 60 to obtain the hinge fixing structure shown in FIG. 5 has the shapes shown in FIGS. 1 to 4 as an example. The connecting member 10 is composed of an inner cylindrical portion 20 and an outer cylindrical portion 30, and has a shaft length sufficiently shorter than the shaft length of the screw 60. Both the inner cylindrical portion 20 and the outer cylindrical portion 30 are made of a material that can tolerate some elastic deformation and retain the shape restoring force that tries to return to the original shape. For example, hard PVC, etc. It can be formed from synthetic resin materials such as acrylic resin, nylon resin, phenol resin, urea resin, melamine resin, polytetrafluoroethylene resin and polypropylene resin, and metal materials such as aluminum and zinc.
内側円筒部２０のネジ６０が挿入される側の端部２１に近い軸方向略半分の領域は、外面に雄ネジ部２３が形成され、内面は平滑面２４とされている。内側円筒部２０の反対側の端部２２に近い軸方向略半分の領域には、軸方向に延長して該端部に開口する複数のスリット２５（図示実施形態では等角度間隔に３つのスリット２５）が形成され、スリット２５の内面にはネジ６０を係合可能な雌ネジ部２６が形成されている。スリット２５を除く該領域の外面は平滑面２７とされている。符号２８は平滑面２４の内部に形成されたネジ挿入空間であり、ネジ６０のネジ山を含めたネジ外径と略同等の内径を有する。雌ネジ部２６は、そのネジ溝内径がネジ挿入空間２８の内径と略同一であり、したがって、そのネジ山はネジ挿入空間２８の平滑面２４より内方に突出している。 A male screw portion 23 is formed on the outer surface of the region of the inner cylindrical portion 20 near the end portion 21 on the side where the screw 60 is inserted, and the inner surface is a smooth surface 24. In a region approximately half in the axial direction near the end 22 on the opposite side of the inner cylindrical portion 20, a plurality of slits 25 extending in the axial direction and opening at the end (three slits at equal intervals in the illustrated embodiment). 25) is formed, and a female screw portion 26 to which the screw 60 can be engaged is formed on the inner surface of the slit 25. The outer surface of the region excluding the slit 25 is a smooth surface 27. Reference numeral 28 is a screw insertion space formed inside the smooth surface 24, and has an inner diameter substantially equal to the outer diameter of the screw including the screw thread of the screw 60. The inner diameter of the female screw groove 26 is substantially the same as the inner diameter of the screw insertion space 28, and therefore the screw thread protrudes inward from the smooth surface 24 of the screw insertion space 28.
外側円筒部３０は、ネジ挿入端部３１に拡径した鍔部３３が形成され、この鍔部３３を除く部分の外面には突起３４が軸方向に沿って複数形成されている。突起３４は、ネジ挿入端部３１側にネジ挿入方向に対して略垂直面となる係合面３４ａを有すると共に、反対側端部３２に向かうにつれて外径が徐々に小さくなる傾斜面３４ｂを有して、断面三角形の楔形状に形成されている。 The outer cylindrical portion 30 has a flange portion 33 having an enlarged diameter formed at the screw insertion end portion 31, and a plurality of protrusions 34 are formed along the axial direction on the outer surface of the portion excluding the flange portion 33. The protrusion 34 has an engaging surface 34a that is substantially perpendicular to the screw insertion direction on the screw insertion end 31 side, and has an inclined surface 34b whose outer diameter gradually decreases toward the opposite end 32. Therefore, it is formed in a wedge shape with a triangular cross section.
外側円筒部３０の内面において、ネジ挿入端部３１に近い軸方向略半分の領域には、内側円筒部２０の雄ネジ部２３と螺合可能な雌ネジ部３５が形成されている。雄ネジ部２３と雌ネジ部３５との螺合により内側円筒部２０の外側に外側円筒部３０が一体に結合されたときに、内側円筒部２０の端部２２に近い軸方向略半分の領域と外側円筒部３０の端部３２に近い軸方向略半分の領域との間に隙間３７が形成されるように、外側円筒部３０の端部３２に近い軸方向略半分の領域の内面は雌ネジ部３５より大きな内径を有する後退面３６として形成されている。 On the inner surface of the outer cylindrical portion 30, a female screw portion 35 that can be screwed with the male screw portion 23 of the inner cylindrical portion 20 is formed in a region substantially half in the axial direction near the screw insertion end portion 31. When the outer cylindrical portion 30 is integrally connected to the outer side of the inner cylindrical portion 20 by screwing the male screw portion 23 and the female screw portion 35, an area approximately half in the axial direction near the end portion 22 of the inner cylindrical portion 20. The inner surface of the approximately half axial region near the end 32 of the outer cylindrical portion 30 is female so that a gap 37 is formed between the outer cylindrical portion 30 and the approximately half axial region near the end 32 of the outer cylindrical portion 30. It is formed as a retracting surface 36 having an inner diameter larger than that of the threaded portion 35.
この連結部材１０は、雄ネジ部２３と雌ネジ部３５との螺合により内側円筒部２０の外側に外側円筒部３０が一体に結合された状態で、ドア４０の閉じ側木口端４１に形成した各連結部材用下穴４３に配置される（図５）。既述したように、連結部材用下穴４３は連結部材１０の外形に応じた形状および寸法に形成されており、より詳しくは、その開口端には外側円筒部３０の鍔部３３を収める拡径部４３ａが形成され、該拡径部４３ａの奥方には突起３４と弾性的に係合する内径寸法を有する筒状部４３ｂが形成されている。連結部材１０を連結部材用下穴４３に挿入するには、突起３４を弾性変形により圧縮させながら、鍔部３３が拡径部４３ａに完全に収まるまで押し込んでいけば良い。このようにして連結部材用下穴４３に所定の位置で配置された連結部材１０は、突起３４が拡径部４３の筒状部４３ｂに圧接して引き抜きに対する抵抗を与えるので、容易には離脱しない安定した取付状態を維持する。連結部材１０の配置は、あらかじめ工場内で、または現場で行うことができる。 The connecting member 10 is formed at the closing end of the door 40 in a state where the outer cylindrical portion 30 is integrally connected to the outer side of the inner cylindrical portion 20 by screwing the male screw portion 23 and the female screw portion 35. It is arranged in the prepared hole 43 for each connecting member (FIG. 5). As described above, the pilot hole 43 for the connecting member is formed in a shape and size corresponding to the outer shape of the connecting member 10, and more specifically, the flange portion 33 of the outer cylindrical portion 30 is accommodated in the opening end thereof. A diameter portion 43a is formed, and a cylindrical portion 43b having an inner diameter dimension that elastically engages with the protrusion 34 is formed behind the diameter expansion portion 43a. In order to insert the connecting member 10 into the pilot hole 43 for the connecting member, the protrusion 34 may be compressed by elastic deformation and pushed in until the flange portion 33 is completely contained in the enlarged diameter portion 43a. The connecting member 10 arranged at a predetermined position in the pilot hole 43 for the connecting member in this way is easily detached because the protrusion 34 presses against the tubular portion 43b of the enlarged diameter portion 43 to give resistance to pulling out. Do not maintain a stable mounting condition. The connecting member 10 can be arranged in advance in the factory or on site.
上記のようにして各連結部材用下穴４３に連結部材１０が配置されたドア４０に丁番５０を取り付けるには、ネジ６０を丁番５０のネジ取付穴５１から連結部材１０の内側円筒部２０のネジ挿入空間２８に押し込んでいく。ネジ６０の先端がネジ挿入空間２８を通過して雌ネジ部２６に当たってからもさらにネジ６０を押し込むと、内側円筒部２０の雌ネジ部２６形成領域をネジ山のピッチごとに拡径させながらさらに前進して、ネジ６０の先端が雌ネジ部２６を通過してネジ用下穴４２に入り込み、最終的にネジ６０の頭部６１が丁番５０のネジ取付穴５１に完全に収まる。連結部材１０を形成する合成樹脂や金属などの材料自体が有する弾性に加えて、内側円筒部２０の雌ネジ部２６形成領域にはスリット２５が形成されており、且つ、該形成領域の拡径を妨げないように隙間３７が形成されているので、押し込まれたネジ６０は雌ネジ部２６のネジ山に当たりながらもスムーズに前進することができる。この際の作業は手またはハンマーなどでネジ６０を真直ぐに押し込むだけであり、ネジ６０を回転させる必要はないので、電動ドライバーなどは不要である。 In order to attach the hinge 50 to the door 40 in which the connecting member 10 is arranged in the prepared hole 43 for each connecting member as described above, the screw 60 is inserted from the screw mounting hole 51 of the hinge 50 to the inner cylindrical portion of the connecting member 10. It is pushed into the screw insertion space 28 of 20. When the screw 60 is pushed in even after the tip of the screw 60 passes through the screw insertion space 28 and hits the female screw portion 26, the female screw portion 26 forming region of the inner cylindrical portion 20 is further expanded by the pitch of the screw thread. Moving forward, the tip of the screw 60 passes through the female screw portion 26 and enters the pilot hole 42 for the screw, and finally the head 61 of the screw 60 completely fits in the screw mounting hole 51 of the chord 50. In addition to the elasticity of the material itself such as synthetic resin or metal forming the connecting member 10, a slit 25 is formed in the female threaded portion 26 forming region of the inner cylindrical portion 20, and the diameter of the formed region is expanded. Since the gap 37 is formed so as not to hinder the screw 60, the pushed screw 60 can move forward smoothly while hitting the thread of the female screw portion 26. The work at this time is only to push the screw 60 straight with a hand or a hammer, and it is not necessary to rotate the screw 60, so that an electric screwdriver or the like is not required.
ネジ６０を最奥まで押し込むことにより丁番５０がドア４０に取り付けられた状態になると、ネジ６０のネジ山が雌ネジ部２６のネジ溝に入り込んで確実に係合されるので、強固な固定構造が維持される。この状態を解除するときは、従来と同様に、電動ドライバーなどの工具を用いてネジ６０を反時計回りに回転させて引き抜けば良い。 When the hinge 50 is attached to the door 40 by pushing the screw 60 all the way in, the screw thread of the screw 60 enters the screw groove of the female screw portion 26 and is securely engaged, so that it is firmly fixed. The structure is maintained. To release this state, the screw 60 may be rotated counterclockwise and pulled out by using a tool such as an electric screwdriver as in the conventional case.
図５に示すようにして丁番５０をドア４０に取り付けるために使用される連結部材についての他の実施形態が図６に示されている。この実施形態（実施例２）による連結部材１０は、内側円筒部２０と外側円筒部３０とがあらかじめ一体的に成形されてなる点において、実施例１の連結部材１０と異なっている。したがって、内側円筒部２０と外側円筒部３０とを一体化させるための連結構成（内側円筒部２０の雄ネジ部２３，外側円筒部３０の雌ネジ部３５）はこの実施形態では不要である。 Another embodiment of the connecting member used to attach the hinge 50 to the door 40 as shown in FIG. 5 is shown in FIG. The connecting member 10 according to this embodiment (Example 2) is different from the connecting member 10 of the first embodiment in that the inner cylindrical portion 20 and the outer cylindrical portion 30 are integrally molded in advance. Therefore, a connecting configuration for integrating the inner cylindrical portion 20 and the outer cylindrical portion 30 (male threaded portion 23 of the inner cylindrical portion 20 and female threaded portion 35 of the outer cylindrical portion 30) is not required in this embodiment.
実施例２の連結部材１０についてのその他の構成や作用などは実施例１の連結部材１０と同様であるので、同一の符号を付して、詳細な説明は省略する。 Since other configurations and operations of the connecting member 10 of the second embodiment are the same as those of the connecting member 10 of the first embodiment, the same reference numerals are given and detailed description thereof will be omitted.
図５に示すようにして丁番５０をドア４０に取り付けるために使用される連結部材についての他の実施形態が図７に示されている。この実施形態（実施例３）による連結部材１０は、内側円筒部２０の雌ネジ部２６形成領域が端部２２に向けて徐々に縮径するように形成されている点において、実施例１の連結部材１０と異なっている。 Another embodiment of the connecting member used to attach the hinge 50 to the door 40 as shown in FIG. 5 is shown in FIG. The connecting member 10 according to this embodiment (Example 3) is formed in that the female screw portion 26 forming region of the inner cylindrical portion 20 is formed so as to gradually reduce the diameter toward the end portion 22. It is different from the connecting member 10.
この実施形態においても、連結部材１０を形成する合成樹脂や金属などの材料自体が有する弾性、および、内側円筒部２０の雌ネジ部２６の外側に形成されたスリット２５の作用により、ネジ６０を押し込んだときに、雌ねじ部２６形成領域が隙間３７の範囲内で雌ねじ部２６形成領域を拡径させることができると共に、ネジ６０を最奥まで押し込んだときに、元の形状に復元しようとする雌ねじ部２６に対してより緊密に係合するので、強固な固定構造が得られる利点がある。 Also in this embodiment, the screw 60 is formed by the elasticity of the material itself such as synthetic resin or metal forming the connecting member 10 and the action of the slit 25 formed on the outside of the female screw portion 26 of the inner cylindrical portion 20. When pushed in, the female screw portion 26 forming region can expand the diameter of the female screw portion 26 forming region within the range of the gap 37, and when the screw 60 is pushed all the way in, it tries to restore to the original shape. Since it engages more tightly with the female thread portion 26, there is an advantage that a strong fixing structure can be obtained.
実施例３の連結部材１０についてのその他の構成や作用などは、実施例１の連結部材１０と同様であるので、同一の符号を付して、詳細な説明は省略する。 Other configurations and operations of the connecting member 10 of the third embodiment are the same as those of the connecting member 10 of the first embodiment. Therefore, the same reference numerals are given and detailed description thereof will be omitted.
図５に示すようにして丁番５０をドア４０に取り付けるために使用される連結部材についての他の実施形態が図８に示されている。この実施形態（実施例４）による連結部材１０は、内側円筒部２０の端部２２側の軸方向略半分の領域（外面にスリット２５が形成された領域）の内面に、雌ネジ部２６に代えて、ネジ挿入空間２８に向けてネジ挿入方向に傾斜する少なくとも一対（図示実施形態では軸方向に等間隔に３対）の突片２９，２９が対向配置されている点において、実施例１の連結部材１０と異なっている。突片２９，２９の先端同士の間隔は、ネジ６０のネジ山を含めた外径よりわずかに小さく、且つ、ネジ６０のネジ山を含まない軸径より大きく形成される。 Another embodiment of the connecting member used to attach the hinge 50 to the door 40 as shown in FIG. 5 is shown in FIG. The connecting member 10 according to this embodiment (Example 4) has a female screw portion 26 on the inner surface of a region (a region in which a slit 25 is formed on the outer surface) substantially half in the axial direction on the end portion 22 side of the inner cylindrical portion 20. Instead, the first embodiment is in that at least a pair of projecting pieces 29, 29 (three pairs at equal intervals in the axial direction in the illustrated embodiment) that are inclined in the screw insertion direction toward the screw insertion space 28 are arranged to face each other. It is different from the connecting member 10 of. The distance between the tips of the projecting pieces 29 and 29 is formed to be slightly smaller than the outer diameter including the screw thread of the screw 60 and larger than the shaft diameter not including the screw thread of the screw 60.
この実施形態によると、ネジ６０を押し込んでいって突片２９，２９間を通過するときに、ネジ６０のネジ山がピッチごとに突片２９，２９の先端にあたりながらその弾性により押し拡げながら前進していく。ネジ６０を最奥まで押し込んだときには、突片２９，２９が元の形状に復元してネジ６０のネジ溝に係合して強固な固定構造を維持する。なお、この実施形態によれば突片２９，２９自体が弾性変形してネジ６０の挿通を許容するので、スリット２５および隙間３７は必ずしも形成する必要がなく、省略することができる。 According to this embodiment, when the screw 60 is pushed in and passes between the projecting pieces 29, 29, the screw thread of the screw 60 hits the tips of the projecting pieces 29, 29 at each pitch and moves forward while being expanded by its elasticity. I will do it. When the screw 60 is pushed all the way in, the projecting pieces 29, 29 are restored to their original shape and engage with the screw groove of the screw 60 to maintain a strong fixing structure. According to this embodiment, since the projecting pieces 29 and 29 themselves are elastically deformed to allow the screw 60 to be inserted, the slit 25 and the gap 37 do not necessarily have to be formed and can be omitted.
実施例４の連結部材１０についてのその他の構成や作用などは、実施例１の連結部材１０と同様であるので、同一の符号を付して、詳細な説明は省略する。 Since other configurations and operations of the connecting member 10 of the fourth embodiment are the same as those of the connecting member 10 of the first embodiment, the same reference numerals are given and detailed description thereof will be omitted.
本発明の好適な他の実施形態（実施例５）について、図９および図１０を参照して以下に詳述する。この実施例では、ドア４０を開閉可能に設置する開口部に立設された縦枠７０のドア閉じ側木口端近くにおいて、丁番５０のネジ取付穴５１に合致させた箇所で内面７１から外面７２に貫通するネジ用下穴７３と、その外面７２に開口する部分を連結部材８０の外形に応じた形状および寸法を有するように拡径させた連結部材用下穴７４とをあらかじめ形成しておき、連結部材用下穴７４に篏合配置した連結部材８０に縦枠内面７１側から丁番５０越しにネジ６０を係合させることにより、丁番５０を建枠７０に固定している（図１０）。ネジ用下穴７３は、ネジ６０の軸径と略同一またはそれより若干大きな内径に形成され、ネジ６０は、縦枠内面７１側から挿入したときに、連結部材用下穴４５に篏合配置された連結部材８０の雌ネジ部９６（後述）に係合されるに十分な軸長を有する。図１０において符号７５は戸当たりを示す。 Another preferred embodiment of the present invention (Example 5) will be described in detail below with reference to FIGS. 9 and 10. In this embodiment, the inner surface 71 to the outer surface are aligned with the screw mounting holes 51 of the hinge 50 near the end of the door closing side of the vertical frame 70 erected in the opening where the door 40 can be opened and closed. A pilot hole 73 for a screw penetrating the 72 and a pilot hole 74 for a connecting member whose diameter is enlarged so as to have a shape and dimensions corresponding to the outer shape of the connecting member 80 are formed in advance. The hinge 50 is fixed to the building frame 70 by engaging the screw 60 from the inner surface 71 side of the vertical frame through the hinge 50 with the connecting member 80 arranged in the pilot hole 74 for the connecting member. FIG. 10). The pilot hole 73 for a screw is formed to have an inner diameter substantially equal to or slightly larger than the shaft diameter of the screw 60, and the screw 60 is arranged in the pilot hole 45 for a connecting member when inserted from the inner surface 71 side of the vertical frame. It has a sufficient axial length to be engaged with the female threaded portion 96 (described later) of the connecting member 80. In FIG. 10, reference numeral 75 indicates a door stop.
図１０に示す丁番固定構造を得るためにネジ６０と共に用いられる連結部材８０は、一例として、図９に示す形状を有する。この連結部材８０は、内側円筒部９０と外側円筒部１００とからなり、ネジ６０の軸長より十分に短い軸長を有する。内側円筒部９０と外側円筒部１００は、いずれも、ある程度の弾性変形を許容すると共に、元の形状に復帰しようとする形状復元力を保持することができる材料で形成され、たとえば、硬質ＰＶＣ、アクリル樹脂、ナイロン樹脂、フェノール樹脂、ユリア樹脂、メラミン樹脂、ポリテトラフルオロエチレン樹脂、ポリプロピレン樹脂などの合成樹脂材料や、アルミ、亜鉛などの金属材料から形成することができる。 The connecting member 80 used together with the screw 60 to obtain the hinge fixing structure shown in FIG. 10 has the shape shown in FIG. 9 as an example. The connecting member 80 is composed of an inner cylindrical portion 90 and an outer cylindrical portion 100, and has an axial length sufficiently shorter than the axial length of the screw 60. Both the inner cylindrical portion 90 and the outer cylindrical portion 100 are made of a material that can tolerate some elastic deformation and retain the shape restoring force that tries to return to the original shape. For example, hard PVC. It can be formed from synthetic resin materials such as acrylic resin, nylon resin, phenol resin, urea resin, melamine resin, polytetrafluoroethylene resin and polypropylene resin, and metal materials such as aluminum and zinc.
内側円筒部９０は、実施例１の内側円筒部２０と同一の形状および構成を有する。すなわち、内側円筒部９０のネジ６０が挿入される側の端部９１に近い軸方向略半分の領域は、外面に雄ネジ部９３が形成され、内面は平滑面９４とされている。内側円筒部９０の反対側の端部９２に近い軸方向略半分の領域には、軸方向に延長して該端部に開口する複数のスリット９５（図示実施形態では等角度間隔に３つのスリット９５）が形成され、スリット９５の内面にはネジ６０を係合可能な雌ネジ部９６が形成されている。スリット９５を除く該領域の外面は平滑面９７とされている。符号９８は平滑面９４の内部に形成されたネジ挿入空間であり、ネジ６０のネジ山を含めたネジ外径と略同等の内径を有する。雌ネジ部９６は、そのネジ溝内径がネジ挿入空間９８の内径と略同一であり、したがって、そのネジ山はネジ挿入空間９８の平滑面９４より内方に突出している。 The inner cylindrical portion 90 has the same shape and configuration as the inner cylindrical portion 20 of the first embodiment. That is, in the region of the inner cylindrical portion 90 near the end 91 on the side where the screw 60 is inserted, the male screw portion 93 is formed on the outer surface and the inner surface is a smooth surface 94. A plurality of slits 95 extending in the axial direction and opening to the end portion in a region approximately half in the axial direction near the end portion 92 on the opposite side of the inner cylindrical portion 90 (three slits at equal intervals in the illustrated embodiment). 95) is formed, and a female screw portion 96 to which the screw 60 can be engaged is formed on the inner surface of the slit 95. The outer surface of the region excluding the slit 95 is a smooth surface 97. Reference numeral 98 is a screw insertion space formed inside the smooth surface 94, and has an inner diameter substantially equal to the outer diameter of the screw including the screw thread of the screw 60. The inner diameter of the female screw groove 96 is substantially the same as the inner diameter of the screw insertion space 98, and therefore the screw thread protrudes inward from the smooth surface 94 of the screw insertion space 98.
外側円筒部１００は、実施例１の外側円筒部３０の内面を同一の形状および構成にして、その外面を軸方向に前後反転させた形状を有する。すなわち、外側円筒部１００のネジ挿入端部１０１と反対側の端部１０２に拡径した鍔部１０３が形成され、この鍔部１０３を除く部分の外面には突起１０４が軸方向に沿って複数形成されている。突起１０４は、端部１０２側にネジ挿入方向に対して略垂直面となる係合面１０４ａを有すると共に、ネジ挿入端部１０１に向かうにつれて外径が徐々に小さくなる傾斜面１０４ｂを有して、断面三角形の楔形状に形成されている。 The outer cylindrical portion 100 has a shape in which the inner surface of the outer cylindrical portion 30 of the first embodiment has the same shape and configuration, and the outer surface thereof is vertically inverted. That is, an enlarged collar portion 103 is formed at the end 102 opposite to the screw insertion end 101 of the outer cylindrical portion 100, and a plurality of protrusions 104 are provided along the axial direction on the outer surface of the portion other than the flange 103. It is formed. The protrusion 104 has an engaging surface 104a on the end 102 side that is substantially perpendicular to the screw insertion direction, and has an inclined surface 104b whose outer diameter gradually decreases toward the screw insertion end 101. , It is formed in the shape of a wedge with a triangular cross section.
外側円筒部１００の内面において、ネジ挿入端部１０１に近い軸方向略半分の領域には、内側円筒部９０の雄ネジ部９３と螺合可能な雌ネジ部１０５が形成されている。雄ネジ部９３と雌ネジ部１０５との螺合により内側円筒部９０の外側に外側円筒部１００が一体に結合されたときに、内側円筒部９０の端部９２に近い軸方向略半分の領域と外側円筒部１００の端部１０２に近い軸方向略半分の領域との間に隙間１０７が形成されるように、外側円筒部１００の端部１０２に近い軸方向略半分の領域の内面は雌ネジ部１０５より大きな内径を有する後退面１０６として形成されている。 On the inner surface of the outer cylindrical portion 100, a female screw portion 105 that can be screwed with the male screw portion 93 of the inner cylindrical portion 90 is formed in a region substantially half in the axial direction near the screw insertion end portion 101. When the outer cylindrical portion 100 is integrally connected to the outer side of the inner cylindrical portion 90 by screwing the male screw portion 93 and the female screw portion 105, a region approximately half in the axial direction near the end portion 92 of the inner cylindrical portion 90. The inner surface of the approximately half axial region close to the end 102 of the outer cylindrical portion 100 is female so that a gap 107 is formed between the outer cylindrical portion 100 and the approximately half region in the axial direction close to the end 102 of the outer cylindrical portion 100. It is formed as a receding surface 106 having an inner diameter larger than that of the threaded portion 105.
この連結部材８０は、雄ネジ部９３と雌ネジ部１０５との螺合により内側円筒部９０の外側に外側円筒部１００が一体に結合された状態で、縦枠７０のドア閉じ側木口端近くの外面に形成した連結部材用下穴７４に配置される（図１０）。既述したように、連結部材用下穴７４は連結部材８０の外形に応じた形状および寸法に形成されており、より詳しくは、その開口端には外側円筒部１００の鍔部１０３を収める拡径部７４ａが形成され、該拡径部７４ａの奥方には突起１０４と弾性的に係合する内径寸法を有する筒状部７４ｂが形成されている。連結部材８０を連結部材用下穴７４に挿入するには、突起１０４を弾性変形により圧縮させながら、鍔部１０３が拡径部７４ａに完全に収まるまで押し込んでいけば良い。このようにして連結部材用下穴７４に所定の位置で配置された連結部材８０は、突起１０４が拡径部７４の筒状部７４ｂに圧接して引き抜きに対する抵抗を与えるので、容易には離脱しない安定した取付状態を維持する。連結部材１０の配置は、あらかじめ工場内で、または現場で行うことができる。 In the connecting member 80, the outer cylindrical portion 100 is integrally connected to the outer side of the inner cylindrical portion 90 by screwing the male screw portion 93 and the female screw portion 105, and the connecting member 80 is near the end of the door closing side of the vertical frame 70. It is arranged in a pilot hole 74 for a connecting member formed on the outer surface of the above (FIG. 10). As described above, the pilot hole 74 for the connecting member is formed in a shape and size corresponding to the outer shape of the connecting member 80, and more specifically, the flange portion 103 of the outer cylindrical portion 100 is accommodated in the opening end thereof. A diameter portion 74a is formed, and a cylindrical portion 74b having an inner diameter dimension that elastically engages with the protrusion 104 is formed behind the diameter expansion portion 74a. In order to insert the connecting member 80 into the pilot hole 74 for the connecting member, the protrusion 104 may be compressed by elastic deformation and pushed in until the flange portion 103 is completely contained in the enlarged diameter portion 74a. The connecting member 80, which is arranged at a predetermined position in the prepared hole 74 for the connecting member in this way, is easily detached because the protrusion 104 presses against the tubular portion 74b of the enlarged diameter portion 74 to give resistance to pulling out. Do not maintain a stable mounting condition. The connecting member 10 can be arranged in advance in the factory or on site.
上記のようにして連結部材用下穴７４に連結部材８０が配置された縦枠７０に丁番５０を取り付けるには、縦枠７０の内面７１側からネジ６０を丁番５０のネジ取付穴５１およびネジ用下穴７３に順次に挿通させ、さらに連結部材８０の内側円筒部９０のネジ挿入空間９８に押し込んでいく。ネジ６０の先端がネジ挿入空間９８を通過して雌ネジ部９６に当たってからもさらにネジ６０を押し込むと、内側円筒部９０の雌ネジ部９６形成領域をネジ山のピッチごとに拡径させながらさらに前進して、最終的にネジ６０の頭部６１が丁番５０のネジ取付穴５１に完全に収まる。このとき、ネジ６０の先端は雌ネジ部９６の範囲内に位置している。連結部材８０を形成する合成樹脂や金属などの材料自体が有する弾性に加えて、内側円筒部９０の雌ネジ部９６形成領域にはスリット９５が形成されており、且つ、該形成領域の拡径を妨げないように隙間１０７が形成されているので、押し込まれたネジ６０は雌ネジ部９６のネジ山に当たりながらもスムーズに前進することができる。この際の作業は手またはハンマーなどでネジ６０を真直ぐに押し込むだけであり、ネジ６０を回転させる必要はないので、電動ドライバーなどは不要である。 In order to attach the hinge 50 to the vertical frame 70 in which the connecting member 80 is arranged in the prepared hole 74 for the connecting member as described above, the screw 60 is inserted from the inner surface 71 side of the vertical frame 70 into the screw mounting hole 51 of the hinge 50. And, it is sequentially inserted into the screw pilot hole 73, and further pushed into the screw insertion space 98 of the inner cylindrical portion 90 of the connecting member 80. When the screw 60 is pushed in even after the tip of the screw 60 passes through the screw insertion space 98 and hits the female screw portion 96, the female screw portion 96 forming region of the inner cylindrical portion 90 is further expanded by the pitch of the screw thread. Moving forward, the head 61 of the screw 60 finally fits completely into the screw mounting hole 51 of the hinge 50. At this time, the tip of the screw 60 is located within the range of the female screw portion 96. In addition to the elasticity of the material itself such as synthetic resin or metal forming the connecting member 80, a slit 95 is formed in the female threaded portion 96 forming region of the inner cylindrical portion 90, and the diameter of the formed region is expanded. Since the gap 107 is formed so as not to hinder the screw 60, the pushed screw 60 can move forward smoothly while hitting the thread of the female screw portion 96. The work at this time is only to push the screw 60 straight with a hand or a hammer, and it is not necessary to rotate the screw 60, so that an electric screwdriver or the like is not required.
ネジ６０を最奥まで押し込むことにより丁番５０が縦枠７０に取り付けられた状態になると、ネジ６０のネジ山が雌ネジ部９６のネジ溝に入り込んで確実に係合されるので、強固な固定構造が維持される。この状態を解除するときは、従来と同様に、電動ドライバーなどの工具を用いてネジ６０を反時計回りに回転させて引き抜けば良い。 When the hinge 50 is attached to the vertical frame 70 by pushing the screw 60 all the way in, the screw thread of the screw 60 enters the screw groove of the female screw portion 96 and is securely engaged, so that it is strong. The fixed structure is maintained. To release this state, the screw 60 may be rotated counterclockwise and pulled out by using a tool such as an electric screwdriver as in the conventional case.
なお、図１０の丁番固定構造を得るために用いる連結部材８０としての一実施形態を図９に示したが、この実施形態の連結部材８０について、実施例２（図６）として既述したように内側円筒部９０と外側円筒部１００とを一体に形成する変形例や、実施例３（図７）として既述したように内側円筒部９０の雌ネジ部９６形成領域を端部９２に向けて徐々に縮径するように形成した変形例や、実施例４（図８）として既述したように内側円筒部９０の内面に雌ネジ部９６に代えて突片（２９）を対設した変形例などを採用しても良い。 An embodiment as a connecting member 80 used to obtain the hinge fixing structure of FIG. 10 is shown in FIG. 9, but the connecting member 80 of this embodiment has already been described as Example 2 (FIG. 6). As described above in a modified example in which the inner cylindrical portion 90 and the outer cylindrical portion 100 are integrally formed, and as described in Example 3 (FIG. 7), the female threaded portion 96 forming region of the inner cylindrical portion 90 is set to the end portion 92. A modified example formed so as to gradually reduce the diameter toward the inside, or a projecting piece (29) is provided on the inner surface of the inner cylindrical portion 90 instead of the female screw portion 96 as described in the fourth embodiment (FIG. 8). You may adopt the modified example.
