Description

本発明は、腰掛を保持する台枠を床側の脚台上に回転可能に支持し、前記台枠の回転に伴い腰掛を、前後両方向それぞれを向く各反転位置に拘束可能に設けて成る腰掛装置に関する。 The present invention provides a seat for supporting a stool for holding a stool on a floor pedestal so that the stool can be constrained at each inversion position facing in both the front and rear directions as the base frame rotates. Relates to the device.

従来より、この種の腰掛装置は、腰掛を保持する台枠を床側の脚台上に回転可能に支持して成り、台枠の回転に伴い腰掛を、一般的には前後両方向それぞれを向く各反転位置に１８０度ずつ回転させて、当該位置にて拘束できるように構成されていた（例えば、特許文献１参照。）。 Conventionally, this type of stool device is configured by rotatably supporting a base frame that holds the stool on a floor pedestal and faces the stool as the base frame rotates, generally in both the front and rear directions. It is configured so that it can be rotated 180 degrees to each inversion position and restrained at that position (see, for example, Patent Document 1).

台枠の底面側の四隅には、腰掛回転中心から全て等距離となるように受板が設けられており、同様に脚台の上面側の四隅にも、各受板を受けて支持するための受部が設けられている。腰掛の通常の固定時（腰掛回転ロック状態）には、台枠の各受板が脚台の各受部に載り上げて、腰掛のガタを防止する効果を奏する。 In the four corners on the bottom side of the base frame, receiving plates are provided so as to be all equidistant from the center of rotation of the seat. Similarly, in order to receive and support each receiving plate also in the four corners on the upper side of the leg stand The receiving part is provided. When the seat is normally fixed (seat rotation lock state), each receiving plate of the base frame is placed on each receiving portion of the leg base, and there is an effect of preventing backlash of the seat.

腰掛を１８０度方向転換（回転）させた場合、台枠の各受板が脚台の対角線上にある別の各受部に再び載り上げるので、腰掛のガタを防止することになる。台枠の受板と脚台の受部とに隙間が生じる場合には、台枠の四隅の受板それぞれに調整用の座金を出し入れして、各受板の下端位置を調整して隙間の管理を行っている。このような調整作業により、ガタの防止を図ることができる。 When the seat is turned (rotated) by 180 degrees, each receiving plate of the base frame is again mounted on each other receiving portion on the diagonal of the leg base, so that the backlash of the seat is prevented. If there is a gap between the receiving plate of the base frame and the receiving part of the leg base, insert adjustment washers into and out of the receiving plates at the four corners of the base frame, and adjust the lower end position of each receiving plate to Management is performed. Such adjustment work can prevent backlash.

しかしながら、前述したような従来の腰掛装置では、台枠の四隅にある各受板が腰掛回転中心から全て等距離にあるため、腰掛の回転動作中に各受板は、回転軌道上に並ぶ隣の受部の上も通過することになる。そのため、受板と隣の受部とが高さ寸法で干渉していると、場合によっては受板が受部に載り上げてしまい、ゴツンという衝撃（当たり）が発生すると共に回転動作を阻害する虞もあった。 However, in the conventional seating device as described above, the receiving plates at the four corners of the underframe are all equidistant from the seating rotation center. It will also pass over the receiving part. Therefore, if the receiving plate and the adjacent receiving portion interfere with each other in the height dimension, the receiving plate may be placed on the receiving portion in some cases, and a shock (hit) is generated and the rotation operation is hindered. There was also a fear.

この回転動作時の当たりや阻害を防止するために、台枠の受板と脚台の受部との隙間を甘くする（隙間を空ける）ことにより、当たりを緩和させるように調整作業を行う。しかし、隙間を甘くするように調整すると、今度は通常時に載る受板と受部の間の隙間が大きくなり、腰掛のガタが多く出てしまうことになる。このため、腰掛のガタも当たりも発生しないようにする調整作業は、困難で時間がかかるという問題があった。 In order to prevent hitting or hindrance during this rotating operation, adjustment work is performed so as to ease the hitting by loosening the gap between the receiving plate of the base frame and the receiving part of the leg base (making a gap). However, if the gap is adjusted so as to be sweetened, the gap between the receiving plate and the receiving portion that is normally placed increases, and a lot of backlash occurs. For this reason, there has been a problem that adjustment work for preventing backlash and hitting of the seat is difficult and takes time.

本発明は、以上のような従来技術の有する問題点に着目してなされたもので、腰掛の固定時における台枠の受板と脚台の受部との隙間をなくすように調整作業を行っても、腰掛の回転動作中における当たりが生じることがなく、当たりを考慮せずに通常時のガタ防止のみを主眼として調整作業を行うことができ、調整作業にかかる時間と労力を削減することができる腰掛装置を提供することを目的としている。 The present invention has been made by paying attention to the above-described problems of the prior art, and performs an adjustment operation so as to eliminate the gap between the base plate receiving plate and the leg base receiving portion when the seat is fixed. However, there is no hitting during the rotation of the seat, and the adjustment work can be performed mainly for preventing the backlash at normal time without considering the hitting, and the time and labor required for the adjustment work can be reduced. An object of the present invention is to provide a stool device that can be used.

前述した目的を達成するための本発明の要旨とするところは、以下の各項の発明に存する。
［１］腰掛（１１）を保持する台枠（２０）を床側の脚台（３０）上に回転可能に支持し、前記台枠（２０）の回転に伴い腰掛（１１）を、前後両方向それぞれを向く各反転位置に拘束可能に設けて成る腰掛装置（１０）において、
前記台枠（２０）の底面側に設けられ、腰掛回転中心を間にして互いに対となる少なくとも２組の受板（２１）と、前記脚台（３０）の上面側に設けられ、腰掛回転中心を間にして互いに対となり、前記腰掛（１１）が前記各反転位置に拘束される際、前記各受板（２１）に係合するように前記各受板（２１）の配置位置に対応する少なくとも２組の受部（３７）とを有し、
前記各受板（２１）を、同じ組ごとにそれぞれ腰掛回転中心から等距離となる位置に配置し、かつ隣同士に位置する別の組の前記各受板（２１）を、それぞれ腰掛回転中心から回転半径が異なる位置に配置したことを特徴とする腰掛装置（１０）。 The gist of the present invention for achieving the object described above resides in the inventions of the following items.
[1] A frame (20) holding the seat (11) is rotatably supported on the floor platform (30), and the seat (11) is moved forward and backward in accordance with the rotation of the frame (20). In the seating device (10) configured to be constrained at each inversion position facing each other,
Provided on the bottom side of the underframe (20) and provided on the upper surface side of the leg base (30) and at least two pairs of receiving plates (21) that are paired with each other with the center of rotation on the back, Corresponding to the arrangement position of each receiving plate (21) so as to engage with each receiving plate (21) when the seat (11) is constrained to each reversal position with the center in between. And at least two sets of receiving parts (37),
Each said receiving plate (21) is arrange | positioned in the position which becomes equidistant from the seat rotation center for every same group, respectively, and each said receiving plate (21) located next to each other is each seat rotation center A seating device (10) characterized in that it is arranged at a position with a different turning radius.

［２］前記台枠（２０）の受板（２１）および／または前記脚台（３０）の受部（３７）は、上下方向の高さ位置を調整可能に設けたことを特徴とする［１］に記載の腰掛装置（１０）。 [2] The receiving plate (21) of the base frame (20) and / or the receiving part (37) of the leg base (30) are provided so that the height position in the vertical direction can be adjusted. 1] The seating device (10) according to [1].

次に前述した解決手段に基づく作用を説明する。
本発明に係る腰掛装置（１０）によれば、腰掛（１１）の固定時には、腰掛（１１）を保持する台枠（２０）側の受板（２１）が、脚台（３０）側にある受部（３７）に載り上げるように係合するため、腰掛（１１）がガタつかないように支えられる。ここで受板（２１）は、台枠（２０）の底面側に、腰掛回転中心を間にして対となるように少なくとも２組設けられ、また受部（３７）は、脚台（３０）の上面側に、同じく腰掛回転中心を間にして対となるように少なくとも２組設けられるので、台枠（２０）は腰掛回転中心の円周方向に沿った複数箇所で支持され、一方向に偏ることなく全体的に安定した状態で、より確実にガタつかないよう支持される。 Next, the operation based on the above solution will be described.
According to the stool device (10) according to the present invention, when the stool (11) is fixed, the receiving plate (21) on the side of the frame (20) that holds the stool (11) is on the side of the leg base (30). Since it engages so that it may mount on a receiving part (37), it is supported so that a seat (11) may not rattle. Here, at least two sets of receiving plates (21) are provided on the bottom side of the base frame (20) so as to be paired with the seating rotation center in between, and the receiving portion (37) is a leg base (30). Since at least two sets are also provided on the upper surface side so as to be paired with the seating rotation center in between, the frame (20) is supported at a plurality of locations along the circumferential direction of the seating rotation center, and in one direction. It is supported so that it will not rattle more reliably in an overall stable state without bias.

各受板（２１）は、同じ組ごとに腰掛回転中心から等距離となる位置に配置されるが、隣同士に位置する別の組の各受板（２１）同士では、それぞれ腰掛回転中心から回転半径が異なる位置に配置される。そのため、各受板（２１）はそれぞれ隣の受板（２１）とは回転軌道が同心円上にずれて異なり、腰掛（１１）の回転動作中に各受板（２１）は、隣に並ぶ受板（２１）に対応していた脚台（３０）側の受部（３７）の上は通過しない。従って、仮に受板（２１）とその隣の受板（２１）に対応する受部（３７）とが高さ寸法で干渉したとしても、腰掛（１１）の回転動作中に受板（２１）が受部（３７）に載り上げるように衝突する「当たり」が生じることはない。 Each receiving plate (21) is arranged at an equal distance from the seat rotation center for each set, but each set of receiving plates (21) located next to each other is spaced from the seat rotation center. The rotation radii are arranged at different positions. For this reason, each receiving plate (21) is different from the adjacent receiving plate (21) in a rotational orbit concentric circle, and each receiving plate (21) is arranged next to each other while the seat (11) is rotating. It does not pass over the receiving part (37) on the side of the footrest (30) corresponding to the plate (21). Accordingly, even if the receiving plate (21) and the receiving portion (37) corresponding to the adjacent receiving plate (21) interfere with each other at the height, the receiving plate (21) during the rotating operation of the seat (11). Does not cause a “hit” that collides so as to be placed on the receiving portion (37).

腰掛装置（１０）の組立時ないし車体取付け時において、腰掛（１１）の固定時におけるガタが万一生じた場合には、台枠（２０）の受板（２１）と脚台（３０）の受部（３７）との隙間をなくすように調整する作業が必要となるが、このような作業により、受板（２１）とその隣の受板（２１）に対応する受部（３７）とが高さ寸法で干渉する結果を招いたとしても、前述したように腰掛（１１）の回転動作中における受板（２１）の当たりは根本的に生じることがない。従って、回転動作時の当たりは考慮せずに、通常の固定時のガタ防止のみを主眼として調整作業を行うことができ、調整作業にかかる時間と労力を削減することが可能となる。 If looseness occurs when the seat (11) is fixed when the seat device (10) is assembled or mounted on the vehicle body, the support plate (21) of the base frame (20) and the leg base (30) An operation of adjusting so as to eliminate the gap with the receiving portion (37) is necessary. By such an operation, the receiving portion (37) corresponding to the receiving plate (21) and the adjacent receiving plate (21) Even if it causes a result of interference with the height dimension, as described above, the contact of the receiving plate (21) during the rotating operation of the seat (11) does not occur fundamentally. Therefore, the adjustment work can be performed mainly for preventing the looseness at the time of normal fixing without considering the hit at the time of the rotating operation, and the time and labor required for the adjustment work can be reduced.

また、前記台枠（２０）の受板（２１）および／または前記脚台（３０）の受部（３７）を、上下方向の高さ位置を調整可能に設けると良い。これにより、台枠（２０）の受板（２１）と脚台（３０）の受部（３７）との隙間をなくすように調整する作業を容易に行うことができる。 Moreover, it is good to provide the receiving plate (21) of the said frame (20) and / or the receiving part (37) of the said leg stand (30) so that the height position of an up-down direction can be adjusted. Thereby, the operation | work which adjusts so that the clearance gap between the receiving plate (21) of a base frame (20) and the receiving part (37) of a leg stand (30) can be performed can be performed easily.

本発明に係る腰掛装置によれば、腰掛の固定時における台枠の受板と脚台の受部との隙間をなくすように調整作業を行っても、腰掛の回転動作中における当たりが生じることがなく、当たりは考慮せずに通常時のガタ防止のみを主眼として調整作業を行うことができ、調整作業にかかる時間と労力を削減することが可能であると共に、根本的に回転動作中に当たりが発生しない構造となり、回転腰掛としての品質が向上する。 According to the seating device according to the present invention, even when the adjustment work is performed so as to eliminate the gap between the base plate receiving plate and the leg base receiving portion when the seating is fixed, the hitting during the rotational operation of the seating occurs. Therefore, it is possible to perform the adjustment work with the focus on preventing backlash during normal operation without considering the hit, and it is possible to reduce the time and labor required for the adjustment work. Therefore, the quality of the rotating seat is improved.

図１１〜図１４に示すように、腰掛装置１０は、例えば鉄道車両内に装備されるものであり、腰掛１１を保持する台枠２０を床側の脚台３０上に回転可能に支持し、前記台枠２０の回転に伴い腰掛１１を、前後両方向それぞれを向く各反転位置に拘束可能に設けて成る。 As shown in FIG. 11 to FIG. 14, the seat device 10 is installed in, for example, a railway vehicle, and supports a base frame 20 that holds the seat 11 on a floor platform 30 on the floor side in a rotatable manner. Along with the rotation of the underframe 20, the seat 11 is provided so as to be restrained at each inversion position facing in both the front and rear directions.

腰掛１１は、そのフレームを成す台枠２０上に２席分を有する座部１２を装着し、座部１２の後端に２席分の背凭れ部１３を別々に起倒可能に支持して成る。本実施の形態では、座部１２および背凭れ部１３は２人掛け用に形成されているが、１人掛け用、あるいは３人掛け用であってもかまわない。台枠２０は、矩形枠状に構成されている。 The seat 11 has a seat portion 12 having two seats mounted on a frame 20 constituting the frame, and supports a backrest portion 13 for two seats at the rear end of the seat portion 12 so that the seat can be tilted separately. Become. In the present embodiment, the seat portion 12 and the backrest portion 13 are formed for two-seaters, but may be for one-seaters or three-seaters. The underframe 20 is configured in a rectangular frame shape.

座部１２の両側端には、それぞれ固定式肘掛け１４が固設されており、また、各背凭れ部１３の間には、可動式肘掛け１５が起倒可能に支持されている。さらに、各背凭れ部１３の後面側には、後方に配置される別の腰掛１１の着席者が使用するための収納式のテーブル１６が設けられている。 Fixed armrests 14 are fixed to both side ends of the seat portion 12, and a movable armrest 15 is supported between the backrest portions 13 so as to be able to rise and fall. Further, a retractable table 16 is provided on the back side of each backrest portion 13 for use by a seated person of another seat 11 disposed on the rear side.

腰掛装置１０は、腰掛１１、台枠２０、脚台３０の他、腰掛１１すなわち台枠２０を１８０度ずつ正逆２方向に回転させるための回転機構と、腰掛１１を各反転位置にそれぞれ拘束するためのロック機構とを有している。なお、台枠２０を回転させるための動力は、着座者の操作による手動でも良く、あるいは電動力により自動的に回転させる駆動機構を備えるように構成しても良い。 The seat device 10 includes a seat 11, a base frame 20, a leg base 30, a rotation mechanism for rotating the seat 11, that is, the base frame 20 in two forward and reverse directions by 180 degrees, and restrains the seat 11 at each inversion position. And a locking mechanism. The power for rotating the underframe 20 may be manually operated by a seated person, or may be configured to include a drive mechanism that automatically rotates by electric power.

図４および図５に示すように、脚台３０は、床に直接立設される脚部３１と、この脚部３１の上端に略水平な状態で固設される矩形枠状の上面部３２とから構成されている。上面部３２の略中央には円孔３３が開設されており、回転機構は前記円孔３３の内縁に沿って上下から円周方向に移動可能に嵌合する一対の回転板３４から成る。上側の回転板３４は、腰掛１１側の台枠２０の底面側に一体に固定される。かかる回転機構により、台枠２０は、前記円孔３３の孔中心を腰掛回転中心として回転可能に支持される。 As shown in FIGS. 4 and 5, the leg stand 30 includes a leg portion 31 standing directly on the floor, and a rectangular frame-shaped upper surface portion 32 fixed to the upper end of the leg portion 31 in a substantially horizontal state. It consists of and. A circular hole 33 is formed substantially at the center of the upper surface portion 32, and the rotation mechanism is composed of a pair of rotating plates 34 that are fitted so as to be movable in the circumferential direction from above and below along the inner edge of the circular hole 33. The upper rotating plate 34 is integrally fixed to the bottom surface side of the base frame 20 on the seat 11 side. By this rotation mechanism, the underframe 20 is rotatably supported with the hole center of the circular hole 33 as the seat rotation center.

また、脚台３０の上面部３２の一側端には、ロック機構の足踏レバー３５が揺動可能に取付けられている。足踏レバー３５の先端側を踏み込んだり解放することにより、足踏レバー３５の基端側に設けられた係合凸部３６が左右方向に出没するよう設定されている。腰掛１１側の台枠２０の両側端には、それぞれ前記足踏レバー３５の係合凸部３６が嵌挿する被係合凹部（図示せず）が設けられている。なお、足踏レバー３５は、付勢ばね３８により係合凸部３６が突出する方向に付勢されている。 In addition, a foot lever 35 of a lock mechanism is swingably attached to one side end of the upper surface portion 32 of the leg base 30. By depressing or releasing the distal end side of the foot pedal 35, the engagement convex portion 36 provided on the base end side of the foot lever 35 is set so as to appear and retract in the left-right direction. Engagement recesses (not shown) into which the engagement projections 36 of the foot pedal 35 are respectively inserted are provided on both side ends of the base frame 20 on the seat 11 side. Note that the foot pedal lever 35 is biased by a biasing spring 38 in a direction in which the engaging convex portion 36 protrudes.

図１〜図３に示すように、腰掛１１側の台枠２０の底面側には、腰掛回転中心を間にして互いに対となる少なくとも２組の受板２１が設けられている。台枠２０は矩形枠状に構成されており、該台枠２０の四隅に位置するように、本実施の形態では２組の受板２１が設けられている。 As shown in FIGS. 1 to 3, at least two sets of receiving plates 21 are provided on the bottom surface side of the base frame 20 on the seat 11 side so as to be paired with each other with the seat rotation center in between. The frame 20 is configured in a rectangular frame shape, and in this embodiment, two sets of receiving plates 21 are provided so as to be positioned at the four corners of the frame 20.

詳しく言えば各受板２１は、図７〜図１０に示すように、台枠２０の底面側の四隅に取付ネジ２２を介して固定されるダンパー２３から成る。ここで取付ネジ２２は、上下方向に移動可能に螺合しており、取付ネジ２２を正逆両方向に回動させることで、上下方向の高さ位置を調整できるようになっている。ダンパー２３は、金属あるいは樹脂により成形すると良い。 Specifically, as shown in FIGS. 7 to 10, each receiving plate 21 includes dampers 23 fixed to four corners on the bottom surface side of the base frame 20 via mounting screws 22. Here, the attachment screw 22 is screwed so as to be movable in the vertical direction, and the height position in the vertical direction can be adjusted by rotating the attachment screw 22 in both forward and reverse directions. The damper 23 is preferably formed of metal or resin.

また、取付ネジ２２の回動によりダンパー２３が下方に移動し、ダンパー２３の上端面と台枠２０の底面側との間に隙間が生じる場合には、図１０に示す高さ位置調整用の座金２４を必要な枚数だけ介装させることになる。座金２４は、金属あるいは樹脂により成形すると良いが、樹脂製の場合には強度を保つために金属製より厚く成形する必要がある。 Further, when the damper 23 is moved downward by the rotation of the mounting screw 22 and a gap is generated between the upper end surface of the damper 23 and the bottom surface side of the frame 20, the height position adjustment shown in FIG. A required number of washers 24 are interposed. The washer 24 is preferably formed of metal or resin, but in the case of resin, the washer 24 needs to be formed thicker than metal in order to maintain strength.

各受板２１は、同じ組ごとにそれぞれ腰掛回転中心から等距離となる位置に配置され、かつ隣同士に位置する別の組の各受板２１は、それぞれ腰掛回転中心から回転半径が異なる位置に配置されている。すなわち、図１中では、右斜め上に延びる対角線上にある一対の受板２１は、左斜め上に延びる対角線上にある一対の受板２１に比べて、腰掛回転中心からの回転半径が長い位置に配置されている。 Each receiving plate 21 is arranged at a position that is equidistant from the seat rotation center for each same group, and each of the other receiving plates 21 that are adjacent to each other has a different rotation radius from the seat rotation center. Is arranged. That is, in FIG. 1, the pair of receiving plates 21 on the diagonal line extending diagonally to the right has a longer radius of rotation from the seat rotation center than the pair of receiving plates 21 extending diagonally to the left. Placed in position.

一方、脚台３０の上面部３２には、腰掛回転中心を間にして互いに対となり、前記腰掛１１（台枠２０）が各反転位置にロック機構によって拘束される際、前記各受板２１に係合するように各受板２１の配置位置に対応する少なくとも２組の受部３７が設けられている。上面部３２も台枠２０と同様に矩形枠状に構成されており、該上面部３２の四隅に位置するように、本実施の形態では２組の受部３７が設けられている。 On the other hand, the upper surface portion 32 of the leg base 30 is paired with each other with the seat rotation center therebetween, and when the seat 11 (the base frame 20) is restrained by the lock mechanism at each inversion position, At least two sets of receiving portions 37 corresponding to the arrangement positions of the receiving plates 21 are provided so as to engage with each other. Similarly to the base frame 20, the upper surface portion 32 is also formed in a rectangular frame shape, and in this embodiment, two sets of receiving portions 37 are provided so as to be positioned at the four corners of the upper surface portion 32.

詳しく言えば各受部３７は、図７〜図９に示すように、上面部３２の上面側の四隅に一体に固設されたブラケットから成る。このブラケットから成る受部３７の上端面部に、前記各受板２１のダンパー２３が係脱するように設定されている。 Specifically, as shown in FIGS. 7 to 9, each receiving portion 37 includes a bracket integrally fixed to four corners on the upper surface side of the upper surface portion 32. The damper 23 of each receiving plate 21 is set to be engaged with and disengaged from the upper end surface portion of the receiving portion 37 made of this bracket.

各受部３７も前記各受板２１と同様に、同じ組ごとにそれぞれ腰掛回転中心から等距離となる位置に配置され、かつ隣同士に位置する別の組の各受部３７は、それぞれ腰掛回転中心からの距離が異なる位置に配置されている。すなわち、図１中では、右斜め上に延びる対角線上にある一対の受部３７は、左斜め上に延びる対角線上にある一対の受部３７に比べて、腰掛回転中心からの距離が長い位置に配置されている。 Similarly to each receiving plate 21, each receiving portion 37 is arranged at a position equidistant from the seat rotation center for each same set, and each receiving portion 37 of another set located next to each other is respectively seated. The distance from the center of rotation is different. That is, in FIG. 1, the pair of receiving portions 37 on the diagonal line extending diagonally to the right is a position where the distance from the seat rotation center is longer than that of the pair of receiving portions 37 diagonally extending to the left. Is arranged.

次に、本腰掛装置１０の作用を説明する。
本腰掛装置１０によれば、腰掛１１の固定時には、図４に示すように、腰掛１１を保持する台枠２０側の受板２１が、脚台３０側にある受部３７に載り上げるように係合するため、腰掛１１がガタつかないように支えられる。ここで受板２１は、台枠２０の底面側の四隅に、腰掛回転中心を間にして対となるように２組あり、また受部３７は、脚台３０の上面側の四隅に、同じく腰掛回転中心を間にして対となるように２組あるので、台枠２０は腰掛回転中心の円周方向に沿った複数箇所で支持され、一方向に偏ることなく全体的に安定した状態で、より確実にガタつかないよう支持される。 Next, the operation of the seat device 10 will be described.
According to the seat device 10, when the seat 11 is fixed, as shown in FIG. 4, the receiving plate 21 on the base frame 20 holding the seat 11 is placed on the receiving portion 37 on the leg base 30 side. Since it engages, the seat 11 is supported so that it may not rattle. Here, there are two sets of receiving plates 21 at the four corners on the bottom surface side of the underframe 20 so as to be paired with the seating rotation center in between, and the receiving portions 37 are similarly formed at the four corners on the upper surface side of the leg base 30. Since there are two pairs so as to be paired with the seat rotation center in between, the underframe 20 is supported at a plurality of locations along the circumferential direction of the seat rotation center and in a generally stable state without being biased in one direction. It is supported so that it will not rattle more reliably.

図１に示すように、各受板２１は、同じ組ごとに腰掛回転中心から等距離となる位置に配置されるが、隣同士に位置する別の組の各受板２１同士では、それぞれ腰掛回転中心から回転半径が異なる位置に配置される。そのため、各受板２１はそれぞれ隣の受板２１とは回転軌道が同心円上にずれて異なり（図１中の矢印参照。）、腰掛１１の回転動作中に各受板２１は、隣に並ぶ受板２１に対応していた脚台３０側の受部３７の上は通過しない。従って、仮に受板２１とその隣の受板２１に対応する受部３７とが高さ寸法で干渉したとしても、腰掛１１の回転動作中に受板２１が受部３７に載り上げるように衝突する「当たり」が生じることはない。 As shown in FIG. 1, each receiving plate 21 is arranged at an equal distance from the center of rotation of the sitting for each same set, but each receiving plate 21 of another set located next to each other has a sitting on each other. The rotation radius is arranged at a position different from the rotation center. For this reason, each receiving plate 21 is different from the adjacent receiving plate 21 in a rotational orbit concentric circle (see the arrow in FIG. 1), and each receiving plate 21 is arranged next to each other while the seat 11 is rotating. It does not pass over the receiving portion 37 on the side of the leg base 30 corresponding to the receiving plate 21. Therefore, even if the receiving plate 21 and the receiving portion 37 corresponding to the adjacent receiving plate 21 interfere with each other in height, the receiving plate 21 collides so that the receiving plate 21 is placed on the receiving portion 37 during the rotation of the seat 11. There is no “winning” that occurs.

腰掛装置１０の組立時ないし車体取付け時において、腰掛１１の固定時におけるガタが万一生じた場合には、台枠２０の受板２１と脚台３０の受部３７との隙間をなくすように調整する作業が必要となる。この作業により、受板２１とその隣の受板２１に対応する受部３７とが高さ寸法で干渉する結果を招いたとしても、前述したように腰掛１１の回転動作中における受板２１の当たりは根本的に生じることがない。従って、回転動作時の当たりを考慮せずに、通常の固定時のガタ防止のみを主眼として調整作業を行うことができ、調整作業にかかる時間と労力を削減することが可能となる。 When looseness occurs when the seat 11 is fixed when the seat device 10 is assembled or mounted on the vehicle body, the gap between the receiving plate 21 of the base frame 20 and the receiving portion 37 of the leg base 30 is eliminated. Adjustment work is required. As a result of this work, even if the receiving plate 21 and the receiving portion 37 corresponding to the adjacent receiving plate 21 interfere with each other in height, as described above, the receiving plate 21 during the rotating operation of the seat 11 is not affected. Wins do not occur fundamentally. Accordingly, the adjustment work can be performed mainly for preventing the looseness at the time of normal fixing without considering the hit at the time of the rotating operation, and the time and labor required for the adjustment work can be reduced.

腰掛１１の固定時におけるガタを調整するためには、図８において、台枠２０側にある受板２１の上下方向の高さ位置を調整すると良い。受板２１と受部３７との間に隙間が生じる場合には、この隙間がなくなる程度に受板２１を下方向へ移動させ、一方、受板２１と受部３７とが上下方向で干渉する場合には、この干渉がなくなる程度に受板２１を上方向へ移動させれば良い。 In order to adjust the backlash when the seat 11 is fixed, it is preferable to adjust the vertical position of the receiving plate 21 on the underframe 20 side in FIG. When a gap is generated between the receiving plate 21 and the receiving portion 37, the receiving plate 21 is moved downward to such an extent that this gap disappears, while the receiving plate 21 and the receiving portion 37 interfere in the vertical direction. In this case, the receiving plate 21 may be moved upward so that the interference is eliminated.

受板２１を構成する取付ネジ２２は上下方向に移動可能に螺合しており、取付ネジ２２を正逆両方向に回動させることで、受板２１が受部３７に実際当接する部位であるダンパー２３の上下方向の高さ位置を調整することができる。ここでダンパー２３が下方に移動し、ダンパー２３の上端面と台枠２０の底面側との間に隙間が生じた場合は、図１０に示す高さ位置調整用の座金２４を必要な枚数だけ介装させることになる。 The mounting screw 22 constituting the receiving plate 21 is screwed so as to be movable in the vertical direction, and the receiving plate 21 is actually in contact with the receiving portion 37 by rotating the mounting screw 22 in both forward and reverse directions. The height position of the damper 23 in the vertical direction can be adjusted. Here, when the damper 23 moves downward and a gap is generated between the upper end surface of the damper 23 and the bottom surface side of the base frame 20, the required number of washers 24 for height position adjustment shown in FIG. Will be intervened.

図１および図２において、腰掛１１を１８０度回転させて向きを反転させる場合には、先ず足踏レバー３５を踏んでロック機構による拘束を解除する。すなわち、足踏レバー３５を踏むことにより、図２において時計方向に揺動すると、係合凸部３６が台枠２０側にある被係合凹部（図示せず）から抜けるので、台枠２０の拘束が解除されて腰掛１１の回転が可能になる。 1 and 2, when the seat 11 is rotated 180 degrees to reverse the direction, the stepping lever 35 is first stepped on to release the restraint by the lock mechanism. That is, by stepping on the foot lever 35 and swinging clockwise in FIG. 2, the engaging convex part 36 comes off from the engaged concave part (not shown) on the base frame 20 side. The restraint is released and the seat 11 can be rotated.

次いで、腰掛１１を保持する台枠２０を１８０度回転させ、もう一方の反転位置になると、付勢ばね３８の付勢力によって足踏レバー３５は元の位置に復帰し、係合凸部３６が台枠２０側にある被係合凹部（図示せず）に嵌挿し、再びロック機構により当該反転位置に台枠２０は腰掛１１と共に拘束されることになる。このような腰掛１１の回転動作中において、前述したように、受板２１が受部３７に載り上げるように衝突する「当たり」が生じることはない。 Next, when the frame 20 holding the seat 11 is rotated 180 degrees and the other reverse position is reached, the foot lever 35 is returned to the original position by the biasing force of the biasing spring 38, and the engagement convex portion 36 is moved. It is inserted into an engaged recess (not shown) on the underframe 20 side, and the underframe 20 is restrained together with the seat 11 at the reversal position again by the lock mechanism. During the rotating operation of the seat 11, such a hit does not occur that the receiving plate 21 collides so as to be placed on the receiving portion 37 as described above.
