Description

【考案の詳細な説明】〔考案の技術分野〕本考案は空気ばね装置に係る。[Detailed explanation of the idea] [Technical field of invention] The present invention relates to an air spring device.

[Technical background of the invention]

従来の空気ばね装置は第１図に示すように構成
されている。すなわち、四辺形の頂点位置に配置
した空気ばね外筒１と、この外筒内に吊シヤフト
２で支持された付加タンク３と、この付加タンク
頂部に取付けた空気ばね４と、この空気ばね４に
支持された定盤５とを有し、付加タンク３間は隣

隣接するもの同志桁７によつて連結されている。
また、１対の付加タンクを連結する桁６間は１対
の横断桁８によつて連結されている。この横断桁
８は、吊シヤフト２の位置を避けてこの位置に設
けられている。 A conventional air spring device is constructed as shown in FIG. That is, an air spring outer cylinder 1 placed at the apex position of a quadrilateral, an additional tank 3 supported by a hanging shaft 2 within this outer cylinder, an air spring 4 attached to the top of this additional tank, and this air spring 4. A pair of adjacent additional tanks 3 are connected by a girder 6, and an adjacent pair of outer cylinders 1 are connected by a girder 7.
Further, the girders 6 connecting the pair of additional tanks are connected by a pair of cross girders 8. This cross beam 8 is provided at this position avoiding the position of the hanging shaft 2.

〔背景技術の問題点〕上記構成の従来の空気ばね装置においては、横
断桁８があるため、桁６，７の形成する四辺形フ
レーム内の物品収納スペースがせまく、リターン
ダクトをフレーム内に収容することはできず、フ
レーム側方に設置しなければならなかつた。その
ため空気ばね装置全体が大型となり、クリーンベ
ンチ内等に設置する場合、クリーンベンチが大型

不都合がある。[Problems with the background art] In the conventional air spring device having the above configuration, since there is a cross girder 8, the space for storing goods in the quadrilateral frame formed by the girders 6 and 7 is small, and the return duct cannot be accommodated in the frame. It was not possible to do so, and it had to be installed on the side of the frame. Therefore, the entire air spring device becomes large-sized, and when installed inside a clean bench or the like, the clean bench becomes large and there is an inconvenience that temperature control of the clean bench becomes difficult.

[Purpose of invention]

本考案は上記の事情に基きなされたもので、フ
レーム内の物品収納スペースの大きな空気ばね装
置を得ることを目的としている。 The present invention was developed based on the above-mentioned circumstances, and aims to provide an air spring device with a large space for storing items within the frame.

[Summary of the idea]

本考案においては、付加タンクの隣接するもの
同志を桁により連結し、付加タンクを支持する吊
シヤフトを一方の桁を貫通させ、外筒上端面に前
記桁を挿通させるために設けた切欠開口を閉鎖す

記目的を達成している。 In the present invention, adjacent additional tanks are connected by a girder, a hanging shaft supporting the additional tank is passed through one girder, and a notch opening is provided in the upper end surface of the outer cylinder to allow the girder to pass through. The purpose is achieved by supporting the upper end of the suspension shaft on a support plate that closes.

[Detailed explanation of the idea]

第１図Ａ，Ｂと同一部分には同一符号を附した
第２図は本考案一実施例要部を示す。この図にお
いて、付加タンク３は隣接するもの同志全部が桁
６で連結されている。而して、一方の桁には吊ボ
ルト２を貫通させる開口９が設けてあり、この吊
シヤフト２上端は外筒１上端に桁６を係合させる
ために設けた切欠１０の開口を閉鎖する支持板１
１に支持されている。 FIG. 2, in which the same parts as in FIGS. 1A and 1B are denoted by the same reference numerals, shows a main part of an embodiment of the present invention. In this figure, all adjacent additional tanks 3 are connected by girders 6. One of the girders is provided with an opening 9 through which the hanging bolt 2 passes, and the upper end of the hanging shaft 2 closes the opening of the notch 10 provided for engaging the girder 6 with the upper end of the outer cylinder 1. Support plate 1
1 is supported.

上記のように本考案空気ばね装置においては、
従来のそれにおける横断桁８を設ける必要がない
ので、フレームの物品収納スペースを大きくする
ことができ、リターンダクトをフレーム内に収納
することができる。 As mentioned above, in the air spring device of the present invention,
Since there is no need to provide the cross beam 8 in the conventional structure, the article storage space of the frame can be increased, and the return duct can be housed within the frame.

なお、吊シヤフト２は第３図に示すように角頭
または平行面取頭２ａを有するものとすれば、従
来の一頭付のものより吊シヤフトの調整を容易に
行い得る。 If the suspension shaft 2 has a square head or parallel-faced head 2a as shown in FIG. 3, the suspension shaft can be adjusted more easily than the conventional one-headed type.

[Effect of idea]

上記から明らかなように、本考案によれば空気
ばね全体を小型化し得るので、これを収容するク
リーンベンチも小型化し得、その温度制御が容易
となる。 As is clear from the above, according to the present invention, the entire air spring can be downsized, so the clean bench that accommodates it can also be downsized, and its temperature can be easily controlled.
