The vertical dimension G1 of the opening 35 is substantially the same as the vertical dimension M of the guide groove 29 (see FIG. 3B).
As shown in FIG. 1, the door fitting portion 37 is fitted into the exposed hole portion 33 of the door surface material 5a. The shaft holding cylinder abutting portion 39 (see FIGS. 4B and 4F) is in contact with the shaft holding cylinder 19 below the guide groove 29 of the shaft holding cylinder 19.

図１、図２及び図５に示すように、カバー材２５は、カバー台座部２３の開口部３５を塞ぐものであり、樹脂材製である。このカバー材２５はカバー材本体４１と、ねじ干渉部４３と、上係合部４５と、下係合部４７とを備えている。
カバー材本体４１は、カバー材２５をカバー台座部２３に取り付けたときにカバー台座部２３の開口部３５を覆う。
図２に示すように、ねじ干渉部４３は、カバー本体４１の裏面に突設してあり、軸固定ねじ２１がガイド溝２９を移動自在な寸法Ｇ２と略同じ寸法Ｇ３としてある。
ねじ干渉部４３が裏面側へ突出する寸法Ｔは、軸固定ねじ２１がねじ孔３１に螺合して、適正な位置までねじ込まれているときには軸固定ねじの頭２１ａに干渉しないが、軸固定ねじ２１がねじ孔３１に螺合して、適正な位置までねじ込まれていないときには軸固定ねじ２１ａの頭に干渉して、カバー材４１が開口部３３を塞ぐことができない寸法としてある。
上係合部４５は、カバー台座部２３の開口部３５の上端部に係合する断面略Ｌ字形状を成す鉤状に形成してある。

ここで、扉端部カバー材７１について説明する。図８及び図１０に示すように、扉５の下端には吊元側部を除く左右方向に亘って扉端部カバー材７１が取り付けてある。
図６に示すように、この扉端部カバー材７１、扉５の下端の室外側面に取り付けた扉端部カバー材受け７３に固定してある。
扉端部カバー材７１は、見付け面部７５と上面部７７と下面部７９とを有する断面略コ字形状を成す軟質樹脂材製であり、見付け面部７５には室内側に向けて突設する嵌合部８１が形成されている。また、上面部７７と下面部７９とには、各々扉端部カバー材受け７３に形成された被係合部８３に係合する係合部８５が形成されている。
扉端部カバー材７１の下面部７９は、扉５の下端見込み面のコーナー部を覆うように室内側に突出する見込み面部７９ａが形成されており、この見込み面部７９ａは、扉端部カバー材受け７３に装着する前の状態（図６に二点鎖線で示す）のときに角度Ｒで上方に傾斜してあり、扉端部カバー材受け７３に装着したときに扉下端の見込み面にぴったりと当接するようにしてある。
扉端部カバー材受け７３は、リベット８７で扉５の下端部に固定してあり、図７に示すように、位置決め孔７３ａと、位置調整可能な長孔７３ｂとが形成されている。
図９に示すように、端部カバー材受け７３の左右両端には、各々キャップ８９が装着してある。 Here, the door end cover material 71 will be described. As shown in FIGS. 8 and 10, a door end cover member 71 is attached to the lower end of the door 5 in the left-right direction excluding the hanging side.
As shown in FIG. 6, the door end cover member 71 and the door end cover member receiver 73 attached to the outdoor side surface at the lower end of the door 5 are fixed.
The door end cover material 71 is made of a soft resin material having a substantially U-shaped cross section having a finding surface portion 75, an upper surface portion 77, and a lower surface portion 79. The fitting is provided on the finding surface portion 75 so as to project toward the indoor side. A joint portion 81 is formed. Further, the upper surface portion 77 and the lower surface portion 79 are formed with engaging portions 85 that engage with engaged portions 83 formed on the door end cover material receiver 73, respectively.
The lower surface portion 79 of the door end cover material 71 is formed with an expected surface portion 79a that protrudes indoors so as to cover the corner portion of the lower end expected surface of the door 5, and this expected surface portion 79a is the door end portion cover material. In the state before being attached to the receiver 73 (indicated by a two-dot chain line in FIG. 6), it is inclined upward at an angle R, and when it is attached to the door end cover material receiver 73, it is perfectly fitted to the prospective surface of the lower end of the door. It is made to contact with.
The door end cover material receiver 73 is fixed to the lower end portion of the door 5 with a rivet 87, and as shown in FIG. 7, a positioning hole 73a and a long hole 73b whose position can be adjusted are formed.
As shown in FIG. 9, caps 89 are respectively attached to the left and right ends of the end cover material receiver 73.

次に、上ピボットヒンジ１５の操作、作用効果について説明する。
図２に示すように、枠３に扉５を建て込む際に、軸固定ねじ２１の頭２１ａを下げることで上ピボット軸１１を軸保持筒１９に対して下げ、扉５を建て込んだ後に、上ピボット軸１１をばね２７（図３参照）の付勢力に順じて扉５の上端から突出させて、軸受け１７に挿入する。上ピボット軸１１の上げ下げに伴ない軸固定ねじ２１がガイド溝２９を上下に移動する。
上ピボット軸１１が軸受け１７に適正に挿入したところで、図１に示すように、軸固定ねじ２１の軸部２１ａを軸保持筒１９のねじ孔３１に螺合させて、軸固定ねじ２１の頭２１ａを締め付け、軸固定ねじ２１を軸保持筒１９に固定する。
その後、カバー材２５をカバー台座部２３の開口部３５に嵌め入れる。カバー材２５は、軸固定ねじ２１が適正に締め付けた状態にあるときには、ねじ干渉部４３が軸固定ねじ２１の頭２１ａを押さえた状態で、カバー本体４１がカバー台座部２３の開口部３５を塞ぐ。このとき、カバー材２５は上係合部４５がカバー台座部２３の開口部３５の上端部に係合し、下係合部４７は開口部３５の下端部に弾性を持って嵌合する。
一方、軸固定ねじ２１がねじ孔３１に螺合していなかったり、螺合していても適正に締め付けていない場合には、軸固定ねじ２１のねじの頭２１ａが適正に締め付けているときよりもカバー台座部２３の開口部側に突設した位置にあるので、カバー台座部２３の開口部３５にカバー材２５を取付けようとすると、ねじ干渉部４３が軸固定ねじ２１の頭２１ａと干渉して、カバー台座部２３の開口部３５を塞ぐことができない。 Next, operations and effects of the upper pivot hinge 15 will be described.
As shown in FIG. 2, when the door 5 is built in the frame 3, the head 21 a of the shaft fixing screw 21 is lowered to lower the upper pivot shaft 11 with respect to the shaft holding cylinder 19 and after the door 5 is built. The upper pivot shaft 11 protrudes from the upper end of the door 5 in accordance with the urging force of the spring 27 (see FIG. 3) and is inserted into the bearing 17. As the upper pivot shaft 11 is raised and lowered, the shaft fixing screw 21 moves up and down the guide groove 29.
When the upper pivot shaft 11 is properly inserted into the bearing 17, the shaft portion 21 a of the shaft fixing screw 21 is screwed into the screw hole 31 of the shaft holding cylinder 19 as shown in FIG. 21 a is tightened, and the shaft fixing screw 21 is fixed to the shaft holding cylinder 19.
Thereafter, the cover material 25 is fitted into the opening 35 of the cover pedestal 23. In the cover material 25, when the shaft fixing screw 21 is properly tightened, the cover body 41 holds the opening 35 of the cover pedestal portion 23 while the screw interference portion 43 presses the head 21a of the shaft fixing screw 21. Block it. At this time, the upper engaging portion 45 of the cover material 25 is engaged with the upper end portion of the opening portion 35 of the cover base portion 23, and the lower engaging portion 47 is fitted with the lower end portion of the opening portion 35 with elasticity.
On the other hand, when the shaft fixing screw 21 is not screwed into the screw hole 31 or is not properly tightened even if screwed, the screw head 21a of the shaft fixing screw 21 is properly tightened. Since the cover member 25 is attached to the opening 35 of the cover pedestal 23, the screw interference part 43 interferes with the head 21 a of the shaft fixing screw 21. Thus, the opening 35 of the cover pedestal 23 cannot be blocked.

本実施の形態によれば、図１に示すように、カバー台座部２３の開口部３５の左右方向の寸法Ｗ２は、軸固定ねじ２１の頭２１ａの左右方向の寸法Ｈよりも小さくしてあるので、使用や経年により軸固定ねじ２１が緩んでカバー台座部２３の開口部３５から軸固定ねじ２１が抜け落ちるのを防止できる。
また、カバー材２５をカバー台座部２３の開口部３５を塞いでいるときには、カバー材２５のねじ干渉部４３が軸固定ねじ２１の頭２１ａを押えることで、使用や経年により軸固定ねじ２１が緩んで抜け落ちるのを防止できる。
上ピボットヒンジ１５の上ピボット軸１１が軸受け１７に適切に挿入されていても、軸固定ねじ２１がねじ孔３１に螺合して、適正な位置までねじ込まれていない場合には、カバー材２５の裏面に設けたねじ干渉部４３が、軸固定ねじ２１の頭２１ａに当接してカバー材２５がカバー台座部２３の開口部３５を塞ぐことができないから、軸固定ねじ２１が上ピボット軸１１を固定しているか否かを確認できる。 According to the present embodiment, as shown in FIG. 1, the horizontal dimension W2 of the opening 35 of the cover pedestal 23 is smaller than the horizontal dimension H of the head 21a of the shaft fixing screw 21. Therefore, it is possible to prevent the shaft fixing screw 21 from coming off from the opening 35 of the cover pedestal portion 23 due to loosening of the shaft fixing screw 21 due to use or aging.
Further, when the cover member 25 is closing the opening 35 of the cover pedestal 23, the screw interference portion 43 of the cover member 25 presses the head 21a of the shaft fixing screw 21, so that the shaft fixing screw 21 can be used depending on use and aging. It can be prevented from loosening and falling off.
Even when the upper pivot shaft 11 of the upper pivot hinge 15 is properly inserted into the bearing 17, if the shaft fixing screw 21 is screwed into the screw hole 31 and is not screwed to an appropriate position, the cover member 25 is used. Since the screw interference part 43 provided on the back surface of the cover member abuts against the head 21a of the shaft fixing screw 21 and the cover member 25 cannot block the opening 35 of the cover pedestal 23, the shaft fixing screw 21 is fixed to the upper pivot shaft 11. Can be confirmed.

扉端部カバー材７１を扉下端部に設けることにより、足のつま先等に、扉５の下端部が当たった場合に、足が傷付くのを防止できる。
