Yes. The engaging pin 27, the pivot 28, and the connecting pin 39 are provided substantially in parallel in the front-rear direction. The connecting pin 39 need not be substantially parallel to the engaging pin 27 and the pivot 28.

上記構成の伸縮門扉において、出入口１を閉じる場合には、扉体５を伸ばして施錠端枠１４を施錠受け枠７に当接し施錠する。そして、中間落とし棒装置１５の落とし棒２３を地面２側の落とし孔２６に落とし込んでロックする。 In the telescopic gate having the above-described configuration, when the doorway 1 is closed, the door body 5 is extended and the locking end frame 14 is brought into contact with the locking receiving frame 7 and locked. Then, the dropping rod 23 of the intermediate dropping rod device 15 is dropped into the dropping hole 26 on the ground 2 side and locked.

このとき中間落とし棒装置１５は、次のように操作する。落とし棒２３を上昇させた状態では、図３（Ａ）に示すように係合具２９の係合部３１が係合ピン２７に係合することにより、落とし棒２３は上昇位置に保持されている。 At this time, the intermediate drop rod device 15 is operated as follows. In the state where the drop bar 23 is raised, the drop bar 23 is held in the raised position by the engagement portion 31 of the engagement tool 29 engaging the engagement pin 27 as shown in FIG. Yes.

落とし棒２３を落とし孔２６に落とし込む場合には、操作体２４を把持して連結桟９に沿って下方へと押し下げる。すると係合部３１の下側の案内部３６が係合ピン２７に対して摺動し、図４に二点鎖線で示すように係合具２９がバネ３０に抗して枢軸２８廻りに離脱方向へと図４のａ矢示方向に回動するため、係合部３１が係合ピン２７から離脱して下方へと通過する。従って、そのまま操作体２４を下方へと操作して落とし棒２３の下端部を地面２側の落とし孔２６に落とし込めば良い。 When dropping the drop bar 23 into the drop hole 26, the operating body 24 is gripped and pushed down along the connecting bar 9. Then, the lower guide portion 36 of the engaging portion 31 slides with respect to the engaging pin 27, and the engaging tool 29 separates around the pivot 28 against the spring 30 as shown by a two-dot chain line in FIG. 4 is rotated in the direction indicated by the arrow a in FIG. 4, the engaging portion 31 is detached from the engaging pin 27 and passes downward. Therefore, it is only necessary to operate the operating body 24 downward to drop the lower end portion of the drop bar 23 into the drop hole 26 on the ground 2 side.

係合ピン２７から離脱した係合具２９は、そのストッパー３２が落とし棒２３の上端に当接した状態にある。そこで、落とし棒２３を落とし孔２６から抜いてロックを解除する場合には、操作体２４を把持して連結桟９に沿って上昇させる。すると連結ピン３９が案内溝３８によって案内されるため、係合具２９を所定の姿勢に維持したままで操作体２４、落とし棒２３が一体に上昇し、落とし棒２３が落とし孔２６から抜ける。 The engaging tool 29 released from the engaging pin 27 is in a state in which its stopper 32 is in contact with the upper end of the drop bar 23. Therefore, when the lock rod 23 is pulled out from the drop hole 26 to release the lock, the operating body 24 is grasped and raised along the connecting bar 9. Then, since the connecting pin 39 is guided by the guide groove 38, the operating body 24 and the dropping bar 23 are integrally lifted while the engaging tool 29 is maintained in a predetermined posture, and the dropping bar 23 comes out of the dropping hole 26.

操作体２４を上昇位置の近傍まで上昇させると、係合部３１の上側の案内部３５が係合ピン２７に対して摺動し、係合具２９がバネ３０に抗して枢軸２８廻りにａ矢示方向に回動する。そして、係合部３１が係合ピン２７を通過すると、係合具２９がバネ３０で戻ってその係合部３１が係合ピン２７に係合し、これによって落とし棒２３、操作体２４を上昇位置に保持することができる。 When the operating body 24 is raised to the vicinity of the raised position, the guide part 35 on the upper side of the engaging part 31 slides with respect to the engaging pin 27, and the engaging tool 29 moves around the pivot 28 against the spring 30. a Turns in the direction of the arrow. When the engaging portion 31 passes through the engaging pin 27, the engaging tool 29 is returned by the spring 30, and the engaging portion 31 engages with the engaging pin 27, whereby the drop bar 23 and the operating body 24 are moved. It can be held in the raised position.

従って、操作体２４を連結桟９に沿って上下方向に直線的に操作することにより保持手段２５の係合ピン２７と係合具２９とを係脱操作することが可能であり、操作体２４により落とし棒２３を容易に操作することができる。また連結桟９に操作体２４を套嵌しているため、扉体５の前後方向の両側から同じ条件で操作体２４を操作することができる。 Accordingly, by operating the operating body 24 linearly in the vertical direction along the connecting bar 9, the engaging pin 27 and the engaging tool 29 of the holding means 25 can be engaged and disengaged. Thus, the drop bar 23 can be easily operated. Further, since the operating body 24 is fitted on the connecting bar 9, the operating body 24 can be operated under the same conditions from both sides of the door body 5 in the front-rear direction.

操作体２４は連結桟９の外周に套嵌された円筒体により構成し、しかも連結桟９の案内溝３８を覆う長さとしているため、従来の摘まみ棒等に比較して見栄えが良くなり扉体５の意匠性が一段と向上する。更に操作体２４が円筒体であるため、操作体２４に何等かのものを引っ掛ける等の惧れも防止できる。 Since the operation body 24 is constituted by a cylindrical body fitted around the outer periphery of the connecting bar 9 and has a length that covers the guide groove 38 of the connecting bar 9, the appearance of the operating body 24 is improved as compared with a conventional knob or the like. The design of the door body 5 is further improved.

このように保持手段２５には磁石式のものを使用することも可能である。なお、永久磁石４９を落とし棒２３に、磁性体５０を連結桟９に夫々設けても良い。 In this way, the holding means 25 may be a magnet type. The permanent magnet 49 may be provided on the drop bar 23 and the magnetic body 50 may be provided on the connecting bar 9.

図１３、図１４は本発明の第４の実施例を例示する。この実施例では、上昇位置と下降位置との間で連結ピン３９を案内する案内溝３８が連結桟９に緩やかな略螺旋状に形成され、その案内溝３８の上端部側に、連結ピン３９が上昇位置で係合する係合凹部５３が設けられている。係合凹部５３と連結ピン３９とにより保持手段２５が構成されている。 13 and 14 illustrate a fourth embodiment of the present invention. In this embodiment, a guide groove 38 that guides the connecting pin 39 between the raised position and the lowered position is formed in the connecting bar 9 in a gentle spiral shape, and on the upper end side of the guide groove 38, the connecting pin 39 is provided. Is provided with an engaging recess 53 that engages at the raised position. The engaging recess 53 and the connecting pin 39 constitute the holding means 25.

この場合には、操作体２４を上昇方向に操作すると、連結ピン３９が連結桟９の案内溝３８に沿って案内されるため、操作体２４が上昇しながら連結桟９廻りに回転する。そして、連結ピン３９が案内溝３８の上端に達した後、操作体２４を若干下げると、連結ピン３９が係合凹部５３に係合して落とし棒２３を上昇位置で保持することができる。 In this case, when the operating body 24 is operated in the upward direction, the connecting pin 39 is guided along the guide groove 38 of the connecting bar 9, so that the operating body 24 rotates around the connecting bar 9 while moving up. When the operating body 24 is slightly lowered after the connecting pin 39 reaches the upper end of the guide groove 38, the connecting pin 39 engages with the engaging recess 53 and the drop bar 23 can be held at the raised position.

このように操作体２４は連結桟９廻りに回転しながら上下動するようにしても良い。また上下方向に略真っ直ぐな案内溝３８の上端側に周方向に凹入する係合凹部５３を形成して、この係合凹部５３で連結ピン３９を保持するようにしても良い。 In this way, the operating body 24 may be moved up and down while rotating around the connecting bar 9. Further, an engaging recess 53 that is recessed in the circumferential direction may be formed on the upper end side of the guide groove 38 that is substantially straight in the vertical direction, and the connecting pin 39 may be held by the engaging recess 53.

図１５は本発明の第５の実施例を例示する。この実施例では、上下方向の角筒材（縦部材）５５内に落とし棒２３が挿入され、その角筒材５５の外周に角筒状の操作体２４が上下動自在に套嵌されている。操作体２４は周方向の一部に上下方向のスリット５６を有し、角筒体とはなっていない。その他の構成は第１又は第２の実施例の中間落とし棒装置１５と略同様である。 FIG. 15 illustrates a fifth embodiment of the present invention. In this embodiment, a drop bar 23 is inserted into an up-and-down square tube member (vertical member) 55, and a square tube-shaped operation body 24 is fitted over the outer periphery of the square tube member 55 so as to be movable up and down. . The operating body 24 has a vertical slit 56 in a part of the circumferential direction, and is not a rectangular tube. Other configurations are substantially the same as those of the intermediate drop bar device 15 of the first or second embodiment.

このように操作体２４は、角筒材５５の外周に套嵌する場合には、その角筒材５５に合わせて角筒状に構成してもよい。つまり、操作体２４は周方向の全周が閉鎖された筒体に限定されるものではなく、周方向の一部にスリット５６その他の切欠きが形成されたものであっても、その全体形状が略筒状を呈する等、筒体に近い形状のものであれば十分である。 Thus, when the operating body 24 is fitted on the outer periphery of the rectangular tube material 55, the operating body 24 may be configured in a rectangular tube shape in accordance with the rectangular tube material 55. That is, the operation body 24 is not limited to a cylindrical body whose entire circumference is closed, and even if the slit 56 or other notches are formed in a part of the circumferential direction, the entire shape of the operation body 24 is not limited. It is sufficient if it has a shape close to a cylindrical body, such as a substantially cylindrical shape.

なお、操作体２４が周方向の一部にスリット５６その他の切欠きが形成された筒体に近い形状の場合、そのスリット５６等の切欠きは、操作体２４を手で把持したときに指先等から外れた位置に配置することが望ましい。 When the operation body 24 has a shape close to a cylindrical body in which a slit 56 or other notch is formed in a part of the circumferential direction, the notch such as the slit 56 is formed on the fingertip when the operation body 24 is gripped by a hand. It is desirable to arrange at a position deviating from the above.

以上、本発明の実施例について詳述したが、この実施例に限定されるものではなく、本発明の趣旨を逸脱しない範囲で種々の変更が可能である。例えば、実施例では、水平リンク式の伸縮門扉の中間落とし棒装置１５を例示しているが、そのこれ以外の落とし棒装置でも同様に採用可能であるし、水平リンク式以外の伸縮門扉は勿論のこと、伸縮門扉以外の各種の門扉の落とし棒装置にも採用可能である。 As mentioned above, although the Example of this invention was explained in full detail, it is not limited to this Example, A various change is possible in the range which does not deviate from the meaning of this invention.

In other words, it can also be used in various types of gate dropping devices other than telescopic gates.

縦部材として連結桟９、角筒材５５を例示し、操作体２４として、その連結桟９、角筒材５５に対応する形状の円筒状、角筒状のものを例示している。しかし、縦部材は落とし棒２３を上下動自在に挿入できる形状であれば十分であり、それが門扉のどの位置に設けられるものであっても良い。また操作体２４は縦部材の外周に上下動自在に套嵌されるものであれば、縦部材と略相似形の断面形状を有するものの他、縦部材と異なる断面形状を有するものでも良い。更に操作体２４は筒体以外のもの、例えば筒状のものでも良い。 As the vertical member, a connecting bar 9 and a rectangular tube material 55 are illustrated, and as the operation body 24, a cylindrical shape and a rectangular tube shape corresponding to the connecting bar 9 and the rectangular tube material 55 are illustrated. However, it is sufficient that the vertical member has a shape that allows the drop bar 23 to be inserted in a vertically movable manner, and it may be provided at any position on the gate. The operation body 24 may have a cross-sectional shape different from that of the vertical member, in addition to a cross-sectional shape substantially similar to that of the vertical member, as long as the operation body 24 can be fitted to the outer periphery of the vertical member. Further, the operation body 24 may be other than a cylinder, for example, a cylinder.

保持手段２５は係合ピン２７、係合具２９等を備えた直線係合式、永久磁石４９を備えた磁石式、操作体２４を回転させて連結ピン３９を係合凹部５３に係合させる回転係合式の他、落とし棒２３を上昇位置に保持できるものであれば何であっても良い。 The holding means 25 is a linear engagement type having an engagement pin 27, an engagement tool 29, etc., a magnet type having a permanent magnet 49, and a rotation for rotating the operating body 24 to engage the connection pin 39 with the engagement recess 53.
