実際に、座11の後部上面に背凭れ12を連結する場合には、座11の後部の接合プレート14bの連結面14b-uに、背凭れ12側の接合プレート17bの連結面17b-lを重ね合わせる。そして、各ボルト24A,24Bを作業孔41に挿し込んだ後に、工具を用いて各ボルト24A,24Bの先端部を背凭れ12側の対応するナット34A,34Bに締め込む。このとき、座フレーム14側の進退部材31は、図7に示すように、ボス部27とほぼ同高さだけ突出している。ナット34A,34Bに対する各ボルト24A,24Bの締め込みが進むと、座フレーム14側のボス部27の端面が背凭れフレーム17側の対応するボス部25Aの端面に強固に押し付けられる。それと同時に、座フレーム14側の進退部材31の端面が背凭れフレーム17側の対応するボス部25Bの端面に強固に押し付けられる。この結果、背凭れ12が座11に対して締結固定される。なお、このとき、座11側のボス部27や進退部材31の周囲に配置されているモールド樹脂16と、背凭れ12側のボス部25A,25Bの周囲に配置されているモールド樹脂16は相互に押し付けられて圧縮変形する。
Actually, when connecting the backrest 12 to the upper surface of the rear part of the seat 11, the connecting surface 17b-l of the joining plate 17b on the backrest 12 side is connected to the connecting surface 14b-u of the joining plate 14b on the rear part of the seat 11. Overlapping. And after inserting each volt | bolt 24A, 24B in the work hole 41, the front-end | tip part of each volt | bolt 24A, 24B is tightened to corresponding nut 34A, 34B by the side of the backrest 12 using a tool. At this time, the advancing and retracting member 31 on the seat frame 14 side protrudes by substantially the same height as the boss portion 27 as shown in FIG. When the bolts 24A and 24B are tightened onto the nuts 34A and 34B, the end surface of the boss portion 27 on the seat frame 14 side is firmly pressed against the end surface of the corresponding boss portion 25A on the backrest frame 17 side. At the same time, the end surface of the advance / retreat member 31 on the seat frame 14 side is firmly pressed against the end surface of the corresponding boss portion 25B on the backrest frame 17 side. As a result, the backrest 12 is fastened and fixed to the seat 11. At this time, the mold resin 16 disposed around the boss 27 on the seat 11 side and the advance / retreat member 31 and the mold resin 16 disposed around the bosses 25A and 25B on the backrest 12 side are mutually connected. It is pressed and deformed by compression.
また、この状態から座11に対する背凭れ12の設置角度を調整する場合には、作業孔41に工具を差し込んで、幅方向中央寄りに配置されているボルト24Bを弛めて取り外す(図9参照)。この後に、図9に示すように、ボルト24Bを取り去った作業孔41から進退部材31の六角孔33に六角レンチ39を挿し込み、六角レンチ39を回すことによって進退部材31の突出高さを変更する。図10は、進退部材31の突出高さを低く変更したときの状態を示している。
Further, when the installation angle of the backrest 12 with respect to the seat 11 is adjusted from this state, a tool is inserted into the work hole 41, and the bolt 24B arranged near the center in the width direction is loosened and removed (see FIG. 9). ). Thereafter, as shown in FIG. 9, the projection height of the advance / retreat member 31 is changed by inserting the hexagon wrench 39 into the hexagon hole 33 of the advance / retreat member 31 from the work hole 41 from which the bolt 24 </ b> B has been removed, and turning the hexagon wrench 39. To do. FIG. 10 shows a state when the protruding height of the advance / retreat member 31 is changed to be low.
次に、この状態から作業孔41に再度ボルト24Bを挿し込み、工具によってボルト24Bの先端部を対応するナット34Bに締め込む。このとき、例えば、図10に示すように進退部材31の突出高さが低く変更されている場合には、ボルト24Bの締め込み可能な量が増大する。こうして、ボルト24Bが締め込まれると、背凭れ12が上部側のボス部25A,27同士の当接部を支点として傾動し、図11に示すように、座11に対する背凭れ12の設置角度が変更される。図11では、座11に対する背凭れ12の開き角度が、図6に示すAからA+αに拡がっている。
また、進退部材31の突出高さを高く変更した場合には、ボルト24Bの締め込み可能な量が減少し、座11に対する背凭れ12の開き角度が減少する。
なお、ボルト24Bが対応するナット34Bに対して締め込まれると、接合プレート14b,17bの撓み許容部40が撓み変形し、それによって進退部材31の端面とボス部25Bとがより広い面積で当接し易くなる。 Next, from this state, thebolt 24B is inserted into the work hole 41 again, and the tip of the bolt 24B is tightened into the corresponding nut 34B with a tool. At this time, for example, when the protruding height of the advance / retreat member 31 is changed to be low as shown in FIG. 10, the amount that the bolt 24B can be tightened increases. Thus, when the bolt 24B is tightened, the backrest 12 tilts with the abutment portion between the upper boss portions 25A and 27 as a fulcrum, so that the installation angle of the backrest 12 relative to the seat 11 is as shown in FIG. Be changed. In FIG. 11, the opening angle of the backrest 12 with respect to the seat 11 extends from A to A + α shown in FIG. 6.
Moreover, when the protrusion height of the advance /retreat member 31 is changed to be high, the amount that the bolt 24B can be tightened decreases, and the opening angle of the backrest 12 with respect to the seat 11 decreases.
When thebolt 24B is tightened against the corresponding nut 34B, the bending allowance portion 40 of the joining plates 14b and 17b is bent and deformed, so that the end surface of the advancing / retreating member 31 and the boss portion 25B are contacted with a wider area. It becomes easy to touch.
また、進退部材31の突出高さを高く変更した場合には、ボルト24Bの締め込み可能な量が減少し、座11に対する背凭れ12の開き角度が減少する。
なお、ボルト24Bが対応するナット34Bに対して締め込まれると、接合プレート14b,17bの撓み許容部40が撓み変形し、それによって進退部材31の端面とボス部25Bとがより広い面積で当接し易くなる。 Next, from this state, the
Moreover, when the protrusion height of the advance /
When the
以上のように、この実施形態に係る椅子1においては、座11側の接合プレート14bに、調整手段を構成するネジ孔30と進退部材31が設けられているため、進退部材31の突出高さを調整することにより、座11に対する背凭れ12の設置角度を容易に、かつ適切に調整することができる。
なお、この実施形態においては、調整手段を構成するネジ孔30と進退部材31が座11側に設けられているが、ネジ孔30と進退部材31は、背凭れ12側に設けられても良い。また、ネジ孔30と進退部材31は、座11側と背凭れ12側の両方に設けられても良い。 As described above, in thechair 1 according to this embodiment, since the screw hole 30 and the advance / retreat member 31 constituting the adjusting means are provided in the joint plate 14b on the seat 11 side, the protrusion height of the advance / retreat member 31 is provided. By adjusting the angle, the installation angle of the backrest 12 with respect to the seat 11 can be adjusted easily and appropriately.
In this embodiment, thescrew hole 30 and the advance / retreat member 31 constituting the adjusting means are provided on the seat 11 side. However, the screw hole 30 and the advance / retreat member 31 may be provided on the backrest 12 side. . Further, the screw hole 30 and the advance / retreat member 31 may be provided on both the seat 11 side and the backrest 12 side.
なお、この実施形態においては、調整手段を構成するネジ孔30と進退部材31が座11側に設けられているが、ネジ孔30と進退部材31は、背凭れ12側に設けられても良い。また、ネジ孔30と進退部材31は、座11側と背凭れ12側の両方に設けられても良い。 As described above, in the
In this embodiment, the
特に、この実施形態に係る椅子1においては、進退部材31がネジ機構37によって高さ調整可能とされているため、進退部材31の突出高さを無段階に容易に微調整することができる。
In particular, in the chair 1 according to this embodiment, since the height of the advance / retreat member 31 can be adjusted by the screw mechanism 37, the protrusion height of the advance / retreat member 31 can be easily finely adjusted steplessly.
また、この実施形態に係る椅子1の場合、背凭れ12と座11の複数箇所の連結手段がすべてボルト24A,24Bとナット34A,34Bを主として構成されているため、什器全体の構成を簡素化できるという利点がある。
Further, in the case of the chair 1 according to this embodiment, all the connecting means at the plurality of locations of the backrest 12 and the seat 11 are mainly composed of the bolts 24A and 24B and the nuts 34A and 34B. There is an advantage that you can.
また、この実施形態に係る椅子1においては、進退部材31に六角孔33が設けられ、その六角孔33が、ボルト24Bの軸部を挿入する挿通孔として機能している。このため、ボルト24Bとナット34Bが相互に締め込まれたときに、ボルト24Bとナット34Bによる締結力が進退部材31に効率良く伝達される。このため、背凭れ12側のボス部25Bと進退部材31とを強固に押し当て、背凭れ12と座11の結合をより強固にすることができる。
Further, in the chair 1 according to this embodiment, the advancing / retreating member 31 is provided with a hexagonal hole 33, and the hexagonal hole 33 functions as an insertion hole for inserting the shaft portion of the bolt 24B. For this reason, when the bolt 24B and the nut 34B are fastened to each other, the fastening force by the bolt 24B and the nut 34B is efficiently transmitted to the advance / retreat member 31. For this reason, the boss portion 25B on the backrest 12 side and the advancing / retreating member 31 can be firmly pressed, and the connection between the backrest 12 and the seat 11 can be further strengthened.
さらに、この実施形態に係る椅子1では、座11側と背凭れ12側の少なくとも一方の接合プレート14b,17bに撓み許容部40が設けられている。よって、ボルト24Bがナット34Bに締め込まれたときに、撓み許容部40が撓み変形することにより、進退部材31の端面とボス部25Bの端面とをより広い面積で当接させることができる。したがって、この構造により、ボルト24Bとナット34Bによる締結固定をより安定させることができる。
Furthermore, in the chair 1 according to this embodiment, the bending allowance portion 40 is provided on at least one of the joining plates 14b and 17b on the seat 11 side and the backrest 12 side. Therefore, when the bolt 24B is tightened into the nut 34B, the bending allowance portion 40 is bent and deformed, whereby the end surface of the advance / retreat member 31 and the end surface of the boss portion 25B can be brought into contact with each other in a wider area. Therefore, with this structure, the fastening and fixing by the bolt 24B and the nut 34B can be further stabilized.
特に、この実施形態においては、背凭れ12と座11の中央領域で突き合わせられるボス部25Bと進退部材31が、背凭れ12と座11の幅方向両側の端縁同士で突き合わせられるボス部25Aとボス部27に対して、背凭れ12の厚み方向と幅方向の両方に離間して配置されている。このため、撓み許容部40の撓み代を容易に大きく確保することができる。したがって、ボルト24Bとナット34Bの締め込み時に、進退部材31の端面とボス部25Bの端面とをより広い面積で当接させ易くなる。
In particular, in this embodiment, the boss 25B and the advancing / retracting member 31 that are abutted in the central region of the backrest 12 and the seat 11 are the boss 25A that is abutted at the edges of the backrest 12 and the seat 11 in the width direction. With respect to the boss portion 27, the backrest 12 is disposed so as to be separated in both the thickness direction and the width direction. For this reason, the bending allowance of the bending | flexion tolerance part 40 can be ensured large easily. Therefore, when the bolt 24B and the nut 34B are tightened, the end surface of the advance / retreat member 31 and the end surface of the boss portion 25B are easily brought into contact with each other over a wider area.
また、この実施形態に係る椅子1においては、座フレーム14側のボス部27と進退部材31の各周囲と、背凭れフレーム17側のボス部25A,25Bの各周囲が弾性変形可能なモールド樹脂16によって被覆されている。このため、座11に対する背凭れ12の設置角度を調整した場合にも、ボス部27,25A,25Bや進退部材31の周囲でモールド樹脂16が弾性変形することによって座11と背凭れ12の間に不要な隙間ができるのを防止することができる。
Further, in the chair 1 according to this embodiment, the mold resin in which each periphery of the boss portion 27 and the advance / retreat member 31 on the seat frame 14 side and each periphery of the boss portions 25A and 25B on the backrest frame 17 side can be elastically deformed. 16 is covered. For this reason, even when the installation angle of the backrest 12 with respect to the seat 11 is adjusted, the mold resin 16 is elastically deformed around the boss portions 27, 25 </ b> A, 25 </ b> B and the advancing / retreating member 31, whereby the space between the seat 11 and the backrest 12. It is possible to prevent unnecessary gaps from being formed.

第2の実施形態の椅子は、第1の実施形態の椅子とは、座フレーム14と背凭れフレーム17の幅方向両側の端縁同士を連結する連結手段の構成が異なっている。 FIG. 12 is a diagram corresponding to FIG. 7 of the first embodiment, and FIG. 13 is a diagram corresponding to FIG. 10 of the first embodiment.
The chair of the second embodiment is different from the chair of the first embodiment in the configuration of the connecting means for connecting the edges of theseat frame 14 and the backrest frame 17 on both sides in the width direction.

The chair of the second embodiment is different from the chair of the first embodiment in the configuration of the connecting means for connecting the edges of the
即ち、座フレーム14の接合プレート14bには、背凭れフレーム17方向に向かって突出する支持ボス50が突設され、支持ボス50に椅子の幅方向に沿って延びる連結ピン51が保持されている。これに対し、背凭れフレーム17の接合プレート17bには、座フレーム14方向に向かって突出する支持ボス52が突設され、その支持ボス52に、連結ピン51が回動可能に嵌合される嵌合孔53(ピン嵌合部)が形成されている。座フレーム14の接合プレート14bと、背凭れフレーム17の接合プレート17bの幅方向両側の端縁同士は、連結ピン51が嵌合孔53に嵌合されることによって相互に連結されている。
なお、この実施形態においては、連結ピン51が座11側に設けられ、嵌合孔53が背凭れ12側に設けられているが、連結ピン51を背凭れ12側に設け、嵌合孔53を座11側に設けても良い。 That is, asupport boss 50 that protrudes toward the backrest frame 17 projects from the joint plate 14 b of the seat frame 14, and the connection pin 51 that extends along the width direction of the chair is held by the support boss 50. . On the other hand, a support boss 52 that protrudes toward the seat frame 14 protrudes from the joining plate 17b of the backrest frame 17, and the connecting pin 51 is rotatably fitted to the support boss 52. A fitting hole 53 (pin fitting portion) is formed. Edges on both sides in the width direction of the joining plate 14 b of the seat frame 14 and the joining plate 17 b of the backrest frame 17 are connected to each other by fitting the connecting pins 51 into the fitting holes 53.
In this embodiment, the connectingpin 51 is provided on the seat 11 side and the fitting hole 53 is provided on the backrest 12 side. However, the connecting pin 51 is provided on the backrest 12 side and the fitting hole 53 is provided. May be provided on the side of the seat 11.
なお、この実施形態においては、連結ピン51が座11側に設けられ、嵌合孔53が背凭れ12側に設けられているが、連結ピン51を背凭れ12側に設け、嵌合孔53を座11側に設けても良い。 That is, a
In this embodiment, the connecting
実際に、座11の後部上面に背凭れ12を連結する場合には、座フレーム14の接合プレート14bの幅方向両側の縁部に保持された連結ピン51を、背凭れフレーム17側の嵌合孔53に嵌合させる。その状態で各ボルト24Bを作業孔41に差し込んだ後に、工具を用いて各ボルト24Bの先端部を背凭れフレーム17側の対応するナット34Bに締め込む。
Actually, when the backrest 12 is connected to the upper surface of the rear portion of the seat 11, the connecting pins 51 held on the edges on both sides in the width direction of the joining plate 14b of the seat frame 14 are fitted on the backrest frame 17 side. Fit into the hole 53. In this state, after inserting each bolt 24B into the work hole 41, the tip of each bolt 24B is tightened into the corresponding nut 34B on the backrest frame 17 side using a tool.
図12は、座フレーム14の接合プレート14bから進退部材31を設定された高さまで突出させた状態を示しており、図13は、図12に示す状態から進退部材31の突出高さを低く変更した状態を示している。
例えば、図12に示す状態から座11に対する背凭れ12の設置角度を増大方向に変更する場合には、第1の実施形態と同様に、ボルト24Bを一旦外して六角レンチ等によって進退部材31を回転させ、それによって進退部材31の突出高さを変更する。この後、取り外したボルト24Bを再度対応するナット34Bに対して締め込む。こうして、ボルト24Bが対応するナット34Bに締め込まれると、背凭れ12が、連結ピン51の嵌合孔53との嵌合部分を支点として傾動し、図13に示すように、座11に対する背凭れ12の設置角度が変更させる。 12 shows a state in which the advance /retreat member 31 protrudes from the joint plate 14b of the seat frame 14 to a set height, and FIG. 13 changes the protrusion height of the advance / retreat member 31 from the state shown in FIG. Shows the state.
For example, when the installation angle of thebackrest 12 with respect to the seat 11 is changed in the increasing direction from the state shown in FIG. 12, the bolt 24B is temporarily removed and the advance / retreat member 31 is moved by a hexagon wrench or the like, as in the first embodiment. By rotating, the protrusion height of the advance / retreat member 31 is changed. Thereafter, the removed bolt 24B is tightened again with respect to the corresponding nut 34B. Thus, when the bolt 24B is tightened to the corresponding nut 34B, the backrest 12 tilts with the fitting portion of the connecting pin 51 with the fitting hole 53 as a fulcrum, and as shown in FIG. The installation angle of the droop 12 is changed.
例えば、図12に示す状態から座11に対する背凭れ12の設置角度を増大方向に変更する場合には、第1の実施形態と同様に、ボルト24Bを一旦外して六角レンチ等によって進退部材31を回転させ、それによって進退部材31の突出高さを変更する。この後、取り外したボルト24Bを再度対応するナット34Bに対して締め込む。こうして、ボルト24Bが対応するナット34Bに締め込まれると、背凭れ12が、連結ピン51の嵌合孔53との嵌合部分を支点として傾動し、図13に示すように、座11に対する背凭れ12の設置角度が変更させる。 12 shows a state in which the advance /

この第2の実施形態に係る椅子は、第1の実施形態と基本構成がほぼ同様であるため、第1の実施形態とほぼ同様の効果を得ることができる。ただし、この第2の実施形態に係る椅子の場合、座フレーム14の接合プレート14bと背凭れフレーム17の接合プレート17bの一部が、連結ピン51と嵌合孔53の嵌合によって回転可能に連結されている。このため、背凭れ12の設置角度を変更するためにボルト24Bを対応するナット34Bに締め込んだときに、連結ピン51と嵌合孔53による嵌合部分を支点として、背凭れ12の角度をスムーズに変化させることができる。したがって、この構造により、背凭れ12の設置角度の調整を容易に行うことが可能になるとともに、座11や背凭れ12の一部に不要な応力が残留するのを抑制することができる。
The chair according to the second embodiment has substantially the same basic configuration as that of the first embodiment, and therefore can obtain substantially the same effect as that of the first embodiment. However, in the case of the chair according to the second embodiment, a part of the joining plate 14 b of the seat frame 14 and the joining plate 17 b of the backrest frame 17 can be rotated by fitting the connecting pin 51 and the fitting hole 53. It is connected. For this reason, when the bolt 24B is tightened to the corresponding nut 34B in order to change the installation angle of the backrest 12, the angle of the backrest 12 is set with the fitting portion formed by the connecting pin 51 and the fitting hole 53 as a fulcrum. It can be changed smoothly. Therefore, with this structure, the installation angle of the backrest 12 can be easily adjusted, and unnecessary stress can be suppressed from remaining in the seat 11 and a part of the backrest 12.
なお、本発明は上記の実施形態に限定されず、その要旨を逸脱しない範囲で種々の設計変更が可能である。例えば、第1の実施形態においては、座11と背凭れ12の幅方向両側の端縁を連結するボルト24A及びナット34A部分には、調整手段であるネジ孔30と進退部材31が設けられていないが、幅方向両側の端縁のボルト24A及びナット34Aの設置部分にも調整手段を設けても良い。また、上記の各実施形態においては、連結手段であるボルト24B及びナット34Bと同軸に調整手段であるネジ孔30と進退部材31とが設けられているが、調整手段は連結手段と離間させて(非同軸に)配置しても良い。たとえば、上記の第1の実施形態において、調整手段であるネジ孔30と進退部材31を座11と背凭れ12の幅方向の中央領域に配置すれば、幅方向中央領域のボルト24B及びナット34Bが不要になる。
In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary. For example, in the first embodiment, a bolt hole 30 and an advancing / retracting member 31 that are adjusting means are provided in bolts 24A and nuts 34A that connect the edges of both sides of the seat 11 and the backrest 12 in the width direction.
