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、たとえば枠部材同士を連結す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枠連結構造に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting member used to connect two members, and more particularly to a connecting member used with screws when connecting frame members, for example. The present invention further relates to a frame connecting structure obtained using this connecting member.

一方の枠部材(たとえば縦枠)の上端部の内側面に他方の枠部材(たとえば上枠)の端面に当接させ、これらを直交状態に結合させて枠体(たとえばドアなどの開口枠)を形成する際の一つの好適な手法として、特許文献1に示される枠連結構造が公知である。この枠連結構造においては、縦枠の上端部に縦枠水平穴を貫通形成すると共に、上枠に該縦枠水平穴と整列するように上枠水平穴を形成し、さらに、上枠の上面から上枠水平穴と連通するように円形の上枠垂直穴を形成し、この上枠垂直穴にその雌ネジが上枠水平穴と略同一軸線となるように配置されたナット状結合具(以下、「ナット」)に、縦枠の外側から縦枠水平穴および上枠水平穴に挿入したボルト状結合具(以下、「ネジ」)を螺合させることにより、上枠と縦枠を連結する。 The inner surface of the upper end of one frame member (for example, a vertical frame) is brought into contact with the end surface of the other frame member (for example, an upper frame), and these are joined in an orthogonal state to form a frame (for example, an opening frame such as a door). A frame connection structure shown in Patent Document 1 is known as one suitable method for forming the . In this frame connection structure, a vertical frame horizontal hole is formed through the upper end of the vertical frame, an upper frame horizontal hole is formed in the upper frame so as to be aligned with the vertical frame horizontal hole, and an upper surface of the upper frame is formed. A circular upper frame vertical hole is formed so as to communicate with the upper frame horizontal hole, and a nut-like fitting ( The upper frame and vertical frame are connected by screwing a bolt-like coupling (hereinafter referred to as "screw") inserted into the vertical frame horizontal hole and the upper frame horizontal hole from the outside of the vertical frame to the "nut"). do.

この枠連結構造によれば、上枠垂直穴に挿入したナットの雌ネジ軸線が上枠水平穴の軸線と若干ずれていても、ネジを挿入してその先端がナットの雌ネジに入り込もうとするときに、ナットを該ずれた角度だけ回転させてネジ軸線と一致させる自動調心作用が働くので、ナットを上枠垂直穴に挿入して配置する際に厳密な位置決めを行う必要がなくなり、枠部材同士の結合作業を容易に行うことができるメリットがある(段落0008)。 According to this frame connection structure, even if the axis of the female screw of the nut inserted into the vertical hole of the upper frame is slightly deviated from the axis of the horizontal hole of the upper frame, the screw is inserted and the tip of the screw tries to enter the female screw of the nut. Occasionally, a self-aligning action will work to rotate the nut by the offset angle to coincide with the screw axis, eliminating the need for strict positioning when inserting and arranging the nut in the vertical hole of the upper frame. There is an advantage that the members can be easily joined together (Paragraph 0008).

しかしながら、この枠連結構造において枠部材同士を結合させるには、ネジをナット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、三方枠では上枠と左右縦枠との2つの連結部において幅方向各2箇所の計4箇所、四方枠では上下枠と左右縦枠との4つの連結部において幅方向各2箇所の計8箇所で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枠連結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 connect the frame members in this frame connection structure, it is necessary to use tools such as heavy electric screwdrivers to screw the screws into the nuts. It must be done at 4 points in total, 2 points each in the width direction at the two joints of the left and right vertical frames, and at 8 points in total, 2 points each in the width direction at the four joints between the upper and lower frames and the left and right vertical frames for the square frame. However, it required a lot of work and time. In recent years, as the number of skilled carpenters has decreased, opportunities for young workers and women who are unfamiliar with the work to do the work have increased. is desired.

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 with reference to examples below.

本発明の好適な一実施形態(実施例)について、図1~図6を参照して以下に詳述する。この実施例では、上枠20の上面から下方に垂直に形成した金具挿入穴25,26にそれぞれ連結部材10,10を所定の位置および所定の向きで収容し、各連結部材10にネジ(またはボルト。以下も同じ。)40を係合させることにより、いわゆる縦勝ちに縦枠30と連結して枠連結構造(図6)を得ている。 A preferred embodiment (example) of the present invention will be described in detail below with reference to FIGS. 1 to 6. FIG. In this embodiment, connecting members 10, 10 are accommodated in metal fitting insertion holes 25, 26 vertically formed downward from the upper surface of the upper frame 20 at predetermined positions and in predetermined directions, and each connecting member 10 is screwed (or By engaging bolts (the same shall apply hereinafter) 40, the frame connecting structure (FIG. 6) is obtained by connecting with the vertical frame 30 in a so-called vertical manner.

図1および図2を参照して、上枠20には、端面21で開口してその長手方向(水平方向)に所要長さ延長する一対の上枠ネジ挿入穴22,23が、上枠20の幅方向に所定間隔をおいてあらかじめ形成されている。すなわち、上枠ネジ挿入穴22,23は水平な軸心を有して平行に延長している。また、上枠ネジ挿入穴22,23の内径は、ネジ40のネジ山を含めた外径より若干大きく形成される。 1 and 2, upper frame 20 is provided with a pair of upper frame screw insertion holes 22 and 23 which open at end face 21 and extend in the longitudinal direction (horizontal direction) of a required length. are formed in advance at predetermined intervals in the width direction. That is, the upper frame screw insertion holes 22 and 23 have horizontal axes and extend in parallel. The inner diameters of the upper frame screw insertion holes 22 and 23 are formed slightly larger than the outer diameter including the thread of the screw 40 .

さらに、上枠20の上面24で開口する金具挿入穴25,26が、上枠ネジ挿入穴22,23が形成されている長さ範囲内においてそれらの直上位置に各々形成され、上枠ネジ挿入穴22,23に連通して、さらにその下方まで若干深く延長している。これら金具挿入穴25,26は垂直な軸心を有する。したがって、上枠20の厚み内において、上枠ネジ挿入穴22は金具挿入穴25と直交状に交差し、上枠ネジ挿入穴23は金具挿入穴26と直交状に交差している。 Further, metal fitting insertion holes 25 and 26 opened at the upper surface 24 of the upper frame 20 are formed directly above the upper frame screw insertion holes 22 and 23 within the length range in which the upper frame screw insertion holes 22 and 23 are formed. It communicates with the holes 22 and 23 and extends slightly deeper below them. These fitting insertion holes 25 and 26 have vertical axes. Therefore, within the thickness of the upper frame 20, the upper frame screw insertion hole 22 intersects the metal fitting insertion hole 25 perpendicularly, and the upper frame screw insertion hole 23 intersects the metal fitting insertion hole 26 perpendicularly.

図示省略されているが、上枠20にはその幅方向両端に上枠ネジ挿入穴22,23および金具挿入穴25,26が同様に形成されており、後述する連結部材10により上枠20と左右縦枠30,30とを直交状に連結して枠体が形成される。 Although not shown, upper frame screw insertion holes 22, 23 and metal fitting insertion holes 25, 26 are similarly formed at both ends in the width direction of the upper frame 20, and the upper frame 20 and the upper frame 20 are connected by connecting members 10, which will be described later. A frame body is formed by connecting the left and right vertical frames 30, 30 in an orthogonal manner.

縦枠30には、その上端近くを厚み方向(水平方向)に貫通する縦枠ネジ挿通穴31,32が幅方向に所定間隔(上枠ネジ挿入穴22,23と同間隔)をおいてあらかじめ形成されている。縦枠ネジ挿通穴31,32の内径は、ネジ40のネジ山を含めた外径より若干大きく形成され、たとえば上枠ネジ挿入穴22,23と同径であって良い。縦枠ネジ挿通穴31,32の幅方向における形成位置は、上枠20と縦枠30を縦勝ちに連結したときに、上枠ネジ挿入穴22,23と整列する位置関係となるように設計されている。縦枠ネジ挿通穴31,32の縦枠外面36側の開口部33,34は、ネジ40の頭部41を受容するため、頭部41の径に応じて拡径されている。符号35は、上枠20の端面21と接合される縦枠30の内面を示す。符号37は、縦枠30の上端面を示す。 In the vertical frame 30, vertical frame screw insertion holes 31, 32 penetrating in the thickness direction (horizontal direction) near the upper end of the vertical frame 30 are provided in advance at predetermined intervals in the width direction (the same intervals as the upper frame screw insertion holes 22, 23). formed. The inner diameters of the vertical frame screw insertion holes 31, 32 are formed slightly larger than the outer diameter including the thread of the screw 40, and may be the same diameter as the upper frame screw insertion holes 22, 23, for example. The formation positions of the vertical frame screw insertion holes 31 and 32 in the width direction are designed so that they are aligned with the upper frame screw insertion holes 22 and 23 when the upper frame 20 and the vertical frame 30 are vertically connected. It is The openings 33 and 34 of the vertical frame screw insertion holes 31 and 32 on the side of the vertical frame outer surface 36 receive the head 41 of the screw 40, so that the diameter of the head 41 is increased. Reference numeral 35 denotes the inner surface of the vertical frame 30 joined to the end surface 21 of the upper frame 20 . A reference numeral 37 indicates the upper end surface of the vertical frame 30 .

図6に示す枠連結構造を得るためにネジ40と共に用いられる連結部材10は、一例として、図3~図5に示す形状を有する。この連結部材10は、略円板状の上面11と下面12、およびこれら上面11と下面12との間に形成される側面13とを有して概して円柱状に形成されている。連結部材10の外径は、上枠20の金具挿入穴25,26の内径と略同一または若干小さく形成される。側面13の下端には面取り14が施され、金具挿入穴25,26への挿入を容易にしている。側面13には、その軸方向と直交する方向(上枠20に配置された状態において略水平方向)に延長して側面13を対向位置で貫通する一対のネジ挿通孔15a,15bが形成される。ネジ挿通孔15a,15bの内径はネジ40のネジ山を含めた外径より若干大きく形成される。 The connecting member 10 used together with the screw 40 to obtain the frame connecting structure shown in FIG. 6 has the shapes shown in FIGS. 3 to 5 as an example. The connecting member 10 has a substantially disk-shaped upper surface 11 , a lower surface 12 , and a side surface 13 formed between the upper surface 11 and the lower surface 12 , and has a generally cylindrical shape. The outer diameter of the connecting member 10 is formed to be substantially the same as or slightly smaller than the inner diameter of the metal fitting insertion holes 25 and 26 of the upper frame 20 . A chamfer 14 is applied to the lower end of the side surface 13 to facilitate insertion into metal fitting insertion holes 25 and 26 . The side surface 13 is formed with a pair of screw insertion holes 15a and 15b extending in a direction orthogonal to the axial direction (substantially horizontal when arranged on the upper frame 20) and penetrating the side surface 13 at opposing positions. . The inner diameters of the screw insertion holes 15a and 15b are slightly larger than the outer diameter of the screw 40 including the threads.

上面11と下面12との間において側面13に囲まれた内部空間16において、ネジ挿入領域(ネジ挿通孔15aからネジ挿入孔15bに向けてネジ40が通る空間領域)に向けて、ネジ挿入方向に傾斜するように、少なくとも一対の突片17a,17bが設けられる。この実施例では、ネジ挿入方向において若干の間隔をおいて2対の突片17a,17bが設けられている(図5)。突片17aは上面11から下方に向けてネジ挿入方向前方に傾斜して設けられ、突片17bは下面12から上方に向けてネジ挿入方向前方に傾斜して設けられている。突片17a,17bの先端同士の間隔sは、ネジ40のネジ山を含めた外径よりわずかに小さく、且つ、ネジ40のネジ山を含まない軸径より大きく形成される。 In the internal space 16 surrounded by the side surface 13 between the upper surface 11 and the lower surface 12, toward the screw insertion area (the space area through which the screw 40 passes from the screw insertion hole 15a toward the screw insertion hole 15b), the screw insertion direction At least a pair of protruding pieces 17a and 17b are provided so as to incline. In this embodiment, two pairs of projecting pieces 17a and 17b are provided with a slight gap in the screw insertion direction (Fig. 5). The projecting piece 17a is provided downwardly from the upper surface 11 and inclined forward in the screw insertion direction, and the projecting piece 17b is provided upwardly from the lower surface 12 so as to be inclined forwardly in the screw inserting direction. The distance s between the tips of the projecting pieces 17a and 17b is slightly smaller than the outer diameter of the screw 40 including the thread and larger than the shaft diameter of the screw 40 not including the thread.

連結部材10の上面11には、一対の係止片18a,18bが形成されている。一対の係止片18a,18bは、側面13の対向位置において側面13から一体に上方に突出するように形成されているが、側面13から外方に向けて傾斜状に突出しており、外圧を受けたときには側面13の外径と略同一外径となるように弾性変形可能である。図においては誇張的に示されているが、係止片18a,18bの外方傾斜角度は実際には3~5度程度で十分であり、これより傾斜角度が大きくなると、連結部材10を金具挿入穴25,26に挿入しにくくなる。 A pair of locking pieces 18 a and 18 b are formed on the upper surface 11 of the connecting member 10 . The pair of locking pieces 18a and 18b are formed so as to integrally protrude upward from the side surface 13 at opposing positions of the side surface 13. They also protrude outward from the side surface 13 in an inclined manner so as to absorb external pressure. When received, it can be elastically deformed so that it has substantially the same outer diameter as the outer diameter of the side surface 13 . Although shown in an exaggerated manner in the drawing, an outward inclination angle of about 3 to 5 degrees is actually sufficient for the locking pieces 18a and 18b. It becomes difficult to insert into the insertion holes 25 and 26. - 特許庁

連結部材10の上面には、さらに、係止片18a,18bの間の中央にこれらと平行に矢印状の方向指示部19が突設されている。方向指示部19は、上方から見たときにネジ挿入方向を示す矢印のような形状を有している。この方向指示部19は、後述するようにして連結部材10を上枠20の金具挿入穴25,26に挿入したときにネジ挿通孔15a,15bがネジ挿入方向と一致する所定の向きとなるように適宜回転させる際の目印として働くと共に、枠連結構造を得た後に破損などにより交換が必要となったときに該破損した連結部材10を金具挿入穴25,26から引き抜く際にラジオペンチなどで方向指示部19を摘んで引き抜きを容易に行えるようにしている。 Further, on the upper surface of the connecting member 10, an arrow-shaped direction indicator 19 is projected in the center between the locking pieces 18a and 18b in parallel with them. The direction indicating portion 19 has an arrow-like shape that indicates the screw insertion direction when viewed from above. The direction indicating portion 19 is arranged so that when the connecting member 10 is inserted into the metal fitting insertion holes 25 and 26 of the upper frame 20 as will be described later, the screw insertion holes 15a and 15b are oriented in a predetermined direction that matches the screw insertion direction. In addition to serving as a mark when properly rotating the frame connection structure, when the damaged connection member 10 needs to be replaced due to damage after obtaining the frame connection structure, radio pliers or the like can be used to pull out the damaged connection member 10 from the metal fitting insertion holes 25 and 26. The direction indicating part 19 is grasped so that it can be easily pulled out.

連結部材10は、後に詳述するような突片17a,17bや係止片18a,18b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から一体成型することができる。あるいは、突片17a,17bを除いて連結部材10をこれらの合成樹脂材料から一体成型し、突片17a,17bを設けた金属板を側面13の内側に金属板を添着しても良い(後述の実施例2参照)。 The connecting member 10 is made of a material that allows elastic deformation of the projecting pieces 17a, 17b and locking pieces 18a, 18b, which will be described in detail later, and that can retain a shape restoring force to restore the original shape. For example, it can be integrally molded from a synthetic resin material such as rigid PVC, acrylic resin, nylon resin, phenolic resin, urea resin, melamine resin, polytetrafluoroethylene resin, or polypropylene resin. Alternatively, the connecting member 10 may be integrally molded from these synthetic resin materials except for the projecting pieces 17a and 17b, and the metal plate provided with the projecting pieces 17a and 17b may be affixed to the inner side of the side surface 13 (described later). (see Example 2).

係止片18a,18bおよび方向指示部19を含めた連結部材10の軸方向長さは、連結部材10を上枠20の金具挿入穴25,26に挿入してネジ挿通孔15a,15bを上枠ネジ挿入穴22,23の軸心に一致する所定の位置および向きに配置したときに、上枠20の上面24から係止片18a,18bおよび方向指示部19が突出せず、好ましくは係止片18a,18bの上面が上枠上面24略面一となるような寸法に形成される(図2および図6参照)。特に、連結部材10の軸方向の全長を金具挿入穴25,26の深さと略同一とし、連結部材10を金具挿入穴25,26の奥底まで挿入したときに、その軸心が自動的に上枠ネジ挿入穴22,23の軸心と一致するように、各部の寸法を設定することが好ましい。これにより、連結部材10を金具挿入穴25,26に所定の位置および向きで配置したときに、ネジ挿通孔15a,15bの軸心は、上枠ネジ挿入穴22,23(および縦枠ネジ挿通穴31,32)の軸心と一致している。 The axial length of the connecting member 10 including the locking pieces 18a and 18b and the direction indicating portion 19 is determined by inserting the connecting member 10 into the metal fitting insertion holes 25 and 26 of the upper frame 20 and screwing the screw insertion holes 15a and 15b upward. Preferably, the locking pieces 18a, 18b and the direction indicating portion 19 do not protrude from the upper surface 24 of the upper frame 20 when they are arranged at predetermined positions and orientations that coincide with the axes of the frame screw insertion holes 22, 23. The upper surfaces of the stopper pieces 18a and 18b are formed to be substantially flush with the upper surface 24 of the upper frame (see FIGS. 2 and 6). In particular, the axial length of the connecting member 10 is substantially the same as the depth of the metal fitting insertion holes 25, 26, and when the connecting member 10 is inserted to the bottom of the metal fitting insertion holes 25, 26, the axial center automatically rises. It is preferable to set the dimensions of each part so as to match the axes of the frame screw insertion holes 22 and 23 . As a result, when the connecting member 10 is arranged in the metal fitting insertion holes 25 and 26 at a predetermined position and orientation, the axes of the screw insertion holes 15a and 15b are aligned with the upper frame screw insertion holes 22 and 23 (and the vertical frame screw insertion holes 22 and 23). It coincides with the axis of the holes 31, 32).

この連結部材10をネジ40と共に用いて図6の枠連結構造を得るには、上枠20と縦枠30とを、上枠20の上面24が縦枠30の上端面37と面一になるように縦勝ちにした位置関係とし、この位置関係において水平方向に整列状態となっている縦枠ネジ挿通穴31,32と上枠ネジ挿入孔22,23に対して各々ネジ40を挿入する(図1および図2参照)。 In order to obtain the frame connecting structure of FIG. 6 by using this connecting member 10 together with the screw 40, the upper frame 20 and the vertical frame 30 are arranged so that the upper surface 24 of the upper frame 20 is flush with the upper end surface 37 of the vertical frame 30. In this positional relationship, the screws 40 are inserted into the vertical frame screw insertion holes 31, 32 and the upper frame screw insertion holes 22, 23 that are horizontally aligned ( 1 and 2).

連結部材10はあらかじめ上枠20の金具挿入穴25,26と上枠ネジ挿入穴22,23との交点位置に上記の所定の向きでセットされる。この所定の向きを得るには、連結部材10の上面に形成された方向指示部19の矢印を、上枠上面24に開口する金具挿入穴25,26の開口から目視しながら、ラジオペンチなどで方向指示部19を摘んでその向きが枠体幅方向と略平行になるように適宜回転させて行うことができ、これにより、ネジ挿通孔15a,15bの軸心が上枠ネジ挿入穴22,23(および縦枠ネジ挿通穴31,32)の軸心と一致する所定の向きが得られる。連結部材10の上端には一対の弾性変形可能な係止片18a,18bが形成されているので、金具挿入穴25,26に挿入していくときに係止片18a,18bがその材質の弾性により金具挿入穴25,26の内径と略同一外径に自動的に収縮する。このようにして金具挿入穴25,26に挿入されれば、その内壁に係止片18a,18bの外面が圧接するので、容易には移動も回転もしないように維持される。したがって、金具挿入穴25,26内において所定の位置および向きに配置された連結部材10は、ラジオペンチなどで方向指示部19を摘んで引き抜いたり回転させたりしない限り、その所定の位置および向きが不慮に変わることはない。よって、この作業をあらかじめ工場などで行っておけば、現場作業において軸心合わせの作業を行う必要がなくなる。 The connecting member 10 is set in advance in the predetermined orientation at the intersection of the metal fitting insertion holes 25 and 26 of the upper frame 20 and the upper frame screw insertion holes 22 and 23 . In order to obtain this predetermined orientation, the arrow of the direction indicating portion 19 formed on the upper surface of the connecting member 10 is visually observed through the openings of the metal fitting insertion holes 25 and 26 that open to the upper surface 24 of the upper frame, and the arrows are pulled with needle-nose pliers or the like. This can be done by pinching the direction indicator 19 and rotating it so that its orientation is substantially parallel to the width direction of the frame body. 23 (and the vertical frame screw insertion holes 31 and 32) are oriented in a predetermined direction. Since a pair of elastically deformable locking pieces 18a and 18b are formed at the upper end of the connecting member 10, the locking pieces 18a and 18b are elastically deformable when being inserted into the fitting insertion holes 25 and 26. automatically shrinks to approximately the same outer diameter as the inner diameter of the fitting insertion holes 25 and 26. When inserted into the metal fitting insertion holes 25 and 26 in this manner, the outer surfaces of the locking pieces 18a and 18b are pressed against the inner walls thereof, so that they are maintained so as not to move or rotate easily. Therefore, the connecting member 10 arranged in a predetermined position and orientation within the metal fitting insertion holes 25 and 26 will not be in a predetermined position and orientation unless the direction indicating portion 19 is grasped with needle-nose pliers or the like and pulled out or rotated. It does not change inadvertently. Therefore, if this work is carried out in advance at a factory or the like, there is no need to carry out shaft centering work in the field work.

なお、ネジ挿通孔15a(この実施例ではネジ挿通孔15bも)は外側の開口部において拡径している(図3および図5参照)ので、金具挿入穴25,26と上枠ネジ挿入孔22,23との交点位置にセットされたときに、ネジ挿通孔15a,15bの軸心が上枠ネジ挿入孔22,23の軸心と厳密に一致していない場合であっても、ネジ40の先端がネジ挿通孔15aに入り込むときに連結部材10を回転させて自動的に軸心合わせを行うことができる(自動調心作用)。 Since the screw insertion holes 15a (also the screw insertion holes 15b in this embodiment) are enlarged in diameter at the outer opening (see FIGS. 3 and 5), the metal fitting insertion holes 25 and 26 and the upper frame screw insertion holes 22, 23, even if the axes of the screw insertion holes 15a, 15b do not exactly coincide with the axes of the upper frame screw insertion holes 22, 23, the screws 40 is inserted into the screw insertion hole 15a, the connecting member 10 can be rotated to automatically align the axes (self-aligning action).

この状態で、ネジ40を縦枠30の外側から縦枠ネジ挿通穴31,32に挿通し、縦枠ネジ挿通穴31,32と整列している上枠ネジ挿入穴22,23に挿入し、これらと軸心が一致する位置に配置されている連結金具10のネジ挿通孔15aから内部空間16を通って反対側のネジ挿通孔15bをネジ40の先端が挿通するに至るまで、ネジ40を押し込む。この際の作業は手またはハンマーなどでネジ40を真直ぐに押し込むだけであり、ネジ40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 this state, the screw 40 is inserted from the outside of the vertical frame 30 through the vertical frame screw insertion holes 31, 32 and into the upper frame screw insertion holes 22, 23 aligned with the vertical frame screw insertion holes 31, 32, The screw 40 is inserted through the internal space 16 from the screw insertion hole 15a of the connecting fitting 10 arranged at the position where the axial center coincides with these until the tip of the screw 40 is inserted through the screw insertion hole 15b on the opposite side. push in. At this time, the screw 40 is simply pushed straight in with a hand or a hammer, and there is no need to rotate the screw 40, so an electric screwdriver or the like is unnecessary.

このようにしてネジ40が連結部材10のネジ挿通孔15aからネジ挿通孔15bに向けて挿入されていくと、ネジ40が一対の突片17a,17bの間で圧接されながら、突片17a,17bの弾性変形を介して前進していき、ネジ頭部41が縦枠30のネジ挿通穴31,32の拡径開口部33,34に収まるまで押し込まれたときに、連結作業が終了する。このとき、突片17a,17bの先端がネジ溝に係合しており、且つ、突片17a,17bはネジ挿入方向に傾斜していることからネジ40が引き抜かれる方向に対してストッパーとして働くので、強固な連結構造が維持される。この連結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40を反時計回りに回転させれば良い。 As the screw 40 is inserted from the screw insertion hole 15a of the connecting member 10 toward the screw insertion hole 15b in this manner, the screw 40 is pressed between the pair of projecting pieces 17a and 17b, When the screw head 41 moves forward through the elastic deformation of 17b and is pushed into the enlarged diameter openings 33 and 34 of the screw insertion holes 31 and 32 of the vertical frame 30, the connecting work is completed. At this time, the tips of the projecting pieces 17a and 17b are engaged with the screw grooves, and the projecting pieces 17a and 17b are inclined in the screw insertion direction, so that they act as stoppers in the direction in which the screw 40 is pulled out. Therefore, a strong connection structure is maintained. To release this connected state, the screw 40 may be rotated counterclockwise using a tool such as an electric screwdriver as in the conventional art.

図1および図2に示すようにして図6の連結構造を得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~図11に示されている。この実施形態(実施例2)による連結部材50は、略円板状の上面51と下面52、およびこれら上面51と下面52との間に形成される側面53とを有して概して円柱状に形成されている。連結部材50の外径は、上枠20の金具挿入穴25,26の内径と略同一または若干小さく形成される。側面53の下端には面取り54が施され、金具挿入穴25,26への挿入を容易にしている。側面53には、その軸方向と直交する方向(上枠20に配置された状態において略水平方向)に延長して側面53を対向位置で貫通する一対のネジ挿通孔55a,55bが形成される。ネジ挿通孔55a,55bの内径はネジ40のネジ山を含めた外径より若干大きく形成される。すなわち、連結部材50は、実施例1の連結部材10と略同様の基本形状を有している。 Another embodiment of a connecting member used to obtain the connecting structure of FIG. 6 as shown in FIGS. 1 and 2 is shown in FIGS. 7-11. The connecting member 50 according to this embodiment (Example 2) has a substantially circular disk-shaped upper surface 51, a lower surface 52, and a side surface 53 formed between the upper surface 51 and the lower surface 52, and has a generally cylindrical shape. formed. The outer diameter of the connecting member 50 is formed to be substantially the same as or slightly smaller than the inner diameter of the metal fitting insertion holes 25 and 26 of the upper frame 20 . A chamfer 54 is applied to the lower end of the side surface 53 to facilitate insertion into the fitting insertion holes 25 and 26 . The side surface 53 is formed with a pair of screw insertion holes 55a and 55b extending in a direction orthogonal to the axial direction (substantially horizontal when arranged on the upper frame 20) and penetrating the side surface 53 at opposing positions. . The inner diameters of the screw insertion holes 55a and 55b are slightly larger than the outer diameter of the screw 40 including the thread. That is, the connecting member 50 has substantially the same basic shape as the connecting member 10 of the first embodiment.

上面51と下面52との間において側面53に囲まれた内部空間56において、ネジ挿入領域(ネジ挿通孔55aからネジ挿入孔55bに向けてネジ40が通る空間領域)に向けて、ネジ挿入方向に傾斜するように、少なくとも一対の突片57a,57bが設けられる。この実施例では、内部空間56が断面矩形状に形成され、その内面に、一対の突片57a,57bを有する金属板(図示実施例では断面コ字状)が添着されている(図9)。より詳しくは、金属板は、ネジ40が最初に挿入されるネジ挿通孔55aと一致するネジ挿通孔(図示せず)を有して内部空間56の前面に添着される前板部57cと、その両端から後方に折り曲げられて内部空間56の側面に添着される一対の側板部57d,57eとからなり、ネジ40の先端部が挿入されるネジ挿通孔55b側が開口する断面コ字状に形成され、突片57aは側板部57dから内方に向けてネジ挿入方向前方に傾斜して設けられ、突片57bは側板部57eから内方に向けてネジ挿入方向前方に傾斜して設けられている。突片57a,57bの先端同士の間隔sは、ネジ40のネジ山を含めた外径よりわずかに小さく、且つ、ネジ40のネジ山を含まない軸径より大きく形成される。 In the internal space 56 surrounded by the side surface 53 between the upper surface 51 and the lower surface 52, toward the screw insertion area (the space area through which the screw 40 passes from the screw insertion hole 55a toward the screw insertion hole 55b), the screw insertion direction At least a pair of protruding pieces 57a and 57b are provided so as to incline. In this embodiment, an internal space 56 is formed to have a rectangular cross section, and a metal plate having a pair of projecting pieces 57a and 57b (in the illustrated embodiment, has a U-shaped cross section) is attached to the inner surface thereof (FIG. 9). . More specifically, the metal plate has a front plate portion 57c attached to the front surface of the internal space 56 and having a screw insertion hole (not shown) matching the screw insertion hole 55a into which the screw 40 is first inserted; It consists of a pair of side plate portions 57d and 57e that are bent rearward from both ends and attached to the side surfaces of the internal space 56, and are formed to have a U-shaped cross section with an opening on the side of the screw insertion hole 55b into which the tip portion of the screw 40 is inserted. The projecting piece 57a is provided inwardly from the side plate portion 57d so as to be inclined forward in the screw insertion direction, and the projecting piece 57b is provided inwardly from the side plate portion 57e so as to be inclined forwardly in the screw inserting direction. there is The distance s between the tips of the projecting pieces 57a and 57b is slightly smaller than the outer diameter of the screw 40 including the thread and larger than the shaft diameter of the screw 40 not including the thread.

なお、実施例1の連結部材10においては突片17a,17bの先端が直線状に形成されている(図3参照)が、この実施例の連結部材50においては突片57a,57bの先端が幅方向両端の円弧状部の間に凹部を有する曲線状に形成されている(図7,図10,図11)。これにより、用いられるネジ40の軸径が若干異なっていても、突片57a,57bの先端を確実にネジ溝に係止させることができる。 In the connecting member 10 of the first embodiment, the tips of the projecting pieces 17a and 17b are linearly formed (see FIG. 3), but in the connecting member 50 of this embodiment the tips of the projecting pieces 57a and 57b It is formed in a curved shape having recesses between the arcuate portions at both ends in the width direction (Figs. 7, 10, and 11). As a result, even if the screw 40 used has a slightly different shaft diameter, the tips of the protruding pieces 57a and 57b can be securely locked in the screw grooves.

連結部材50の上面51には、一対の係止片58a,58bおよび方向指示部59が形成されている。これらの形状および作用は、実施例1の連結部材10における一対の係止片18a,18bおよび方向指示部19と同様であるので、説明を省略する。また、連結部材50の各部の寸法と上枠20の金具挿入穴25,26の深さなどとの関係についても、実施例1と同様に設定することができるので、説明を省略する。 A pair of locking pieces 58 a and 58 b and a direction indicating portion 59 are formed on the upper surface 51 of the connecting member 50 . Since these shapes and functions are the same as the pair of locking pieces 18a and 18b and the direction indicating portion 19 in the connecting member 10 of the first embodiment, description thereof will be omitted. Also, the relationship between the dimensions of each part of the connecting member 50 and the depths of the metal fitting insertion holes 25 and 26 of the upper frame 20 can be set in the same manner as in the first embodiment, so description thereof will be omitted.

連結部材50は、係止片18a,18bの弾性変形を許容するために、突片57a,57bを有する金属板を除いて、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から一体成型することができる。 In order to allow the elastic deformation of the locking pieces 18a and 18b, the connecting member 50 can retain the shape restoring force to restore the original shape except for the metal plate having the projecting pieces 57a and 57b. For example, it can be integrally molded from a synthetic resin material such as rigid PVC, acrylic resin, nylon resin, phenolic resin, urea resin, melamine resin, polytetrafluoroethylene resin, or polypropylene resin.

この連結部材50をネジ40と共に用いて図6の枠連結構造を得るには、実施例1と同様に、上枠20と縦枠30とを、上枠20の上面24が縦枠30の上端面37と面一になるように縦勝ちにした位置関係とし、この位置関係において水平方向に整列状態となっている縦枠ネジ挿通穴31,32と上枠ネジ挿入穴22,23に対して各々ネジ40を挿入する(図1および図2参照)。上枠20の金具挿入穴25,26には、あらかじめ工場において、または現場作業により、それぞれ連結部材50が所定の位置および向きで配置されているので、ネジ40を挿入していくと、その先端がネジ挿通孔55aを通過し、内部空間56に入り込み、突片57a,57bの先端に当たってこれらを弾性変形させながら前進し、ネジ頭部41が縦枠30のネジ挿通穴31,32の拡径開口部33,34に収まるまで押し込まれたときに、連結作業が終了する。このとき、突片57a,57bの先端がネジ溝に係合しており、且つ、突片57a,57bはネジ挿入方向に傾斜していることからネジ40が引き抜かれる方向に対してストッパーとして働くので、強固な連結構造が維持される。この連結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40を反時計回りに回転させれば良い。 In order to obtain the frame connection structure of FIG. 6 by using this connection member 50 together with the screw 40, the upper frame 20 and the vertical frame 30 are connected to each other so that the upper surface 24 of the upper frame 20 is above the vertical frame 30, as in the first embodiment. The vertical frame screw insertion holes 31, 32 and the upper frame screw insertion holes 22, 23 are horizontally aligned in this positional relationship. Insert each screw 40 (see FIGS. 1 and 2). The connecting members 50 are placed in predetermined positions and orientations in advance in the metal fitting insertion holes 25 and 26 of the upper frame 20 at the factory or by on-site work. passes through the screw insertion hole 55a, enters the internal space 56, hits the tips of the projecting pieces 57a and 57b and advances while elastically deforming them, and the screw head 41 expands the diameter of the screw insertion holes 31 and 32 of the vertical frame 30. When it is pushed into the openings 33 and 34, the connecting work is completed. At this time, the tips of the protruding pieces 57a and 57b are engaged with the screw grooves, and the protruding pieces 57a and 57b are inclined in the screw insertion direction, so that they act as stoppers in the direction in which the screw 40 is pulled out. Therefore, a strong connection structure is maintained. To release this connected state, the screw 40 may be rotated counterclockwise using a tool such as an electric screwdriver as in the conventional art.

以上においては、上枠20と縦枠30をいわゆる縦勝ちに連結して枠連結構造(図6)を得る際に連結金具10を用いるものとして説明したが、図12に示すように、上枠20と縦枠30をいわゆる横勝ちに連結して枠連結構造を得る際に連結金具10を用いても良い。この場合は、上枠20の左右木口端近くに上枠ネジ挿通穴27を垂直方向に貫通形成すると共に、これと整列するように縦枠30の上端木口から垂直方向に所定深さまで縦枠ネジ挿入穴38を形成し、縦枠30の外面から内方に向けて水平に形成した金具挿入穴39に、そのネジ挿通孔15a,15b(実施例1)/55a,55b(実施例2)が上枠ネジ挿通穴27および縦枠ネジ挿入穴38と整列する所定の位置および所定の向きで配置すれば良い。 In the above description, the upper frame 20 and the vertical frame 30 are connected in a so-called vertical manner to obtain the frame connection structure (FIG. 6) using the connection metal fittings 10. However, as shown in FIG. The connecting metal fittings 10 may be used when connecting the vertical frame 20 and the vertical frame 30 in a so-called horizontal manner to obtain a frame connection structure. In this case, upper frame screw insertion holes 27 are vertically formed near the left and right butt ends of the upper frame 20, and the vertical frame screws are vertically inserted to a predetermined depth from the upper end butt of the vertical frame 30 so as to be aligned therewith. Insertion holes 38 are formed, and screw insertion holes 15a, 15b (Example 1)/55a, 55b (Example 2) are formed in metal fitting insertion holes 39 formed horizontally from the outer surface of the vertical frame 30 toward the inside. They may be arranged at predetermined positions and in predetermined directions aligned with the upper frame screw insertion holes 27 and the vertical frame screw insertion holes 38 .

以上に本発明について実施例を挙げて詳述したが、本発明はこれらに限定されるものではなく、特許請求の範囲に記載された発明の範囲内において多種多様に変形ないし変更して実施可能である。たとえば、実施例1の連結部材10にはネジ挿入方向に若干の間隔をおいて2対の突片17a,17bが設けられ、実施例2の連結部材50には一対の突片57a,57bが設けられているが、2部材の連結に要求される連結力(結合強度)に応じて、突片の対の数を適宜増減して設けることができる。 Although the present invention has been described in detail above with reference to examples, the present invention is not limited to these, and can be implemented with various modifications or changes within the scope of the invention described in the claims. is. For example, the connecting member 10 of the first embodiment is provided with two pairs of projecting pieces 17a and 17b with a slight interval in the screw insertion direction, and the connecting member 50 of the second embodiment is provided with a pair of projecting pieces 57a and 57b. Although provided, the number of pairs of projecting pieces can be appropriately increased or decreased according to the connecting force (bonding strength) required for connecting two members.

また、突片を形成する材質についても、2部材の連結に要求される連結力(結合強度)に応じて合成樹脂材料や金属片などから適宜に選択することができ、一般に、要求される連結力が比較的小さい用途には合成樹脂材料を選択し、要求される連結力が比較的大きい用途には金属板を選択することが好ましいと言える。 Also, the material for forming the projecting piece can be appropriately selected from synthetic resin materials, metal pieces, etc. according to the connecting force (bonding strength) required for connecting the two members. It can be said that it is preferable to select a synthetic resin material for applications in which the force is relatively small, and to select a metal plate for applications in which the required coupling force is relatively large.

また、本発明の連結部材の好適な一用途として、上枠と縦枠とを直交状態に連結して枠連結構造を得ることについて実施例を挙げて説明したが、本発明の連結部材はこの用途に限定されず、広く2部材を連結ないし締結するために用いることができる。 In addition, as a preferred use of the connecting member of the present invention, an embodiment has been described in which the upper frame and the vertical frame are connected in an orthogonal state to obtain a frame connecting structure. The application is not limited, and it can be widely used to connect or fasten two members.
