Description

【0001】
【発明の属する技術分野】
本発明は、請求項1の前文(プリアンブル部分、所謂おいて部分)に従う可調長さの支柱、及び請求項5の前文(プリアンブル部分、所謂おいて部分)に従う直立管に関するものである。
【0002】
【従来の技術及び発明が解決しようとする課題】
可調長さの支柱の種概念は、ヨーロッパ特許第366889号(EP 0 366 889 B1、米国特許第4 969 619号に対応する)から公知である。これらの公知の支柱において、直立管の下端は、内側に向かって曲がっていて、ほぼ半円の断面領域を有し、長手方向中央軸線の方向において且つ直立管の内側に向かって溝開口を形成する。ボトムプレートは、前記下端の前部上に支持される。前部は、直立管の内壁から間隔をあけられている。直立管の上端部に向かって、ボトムプレートは、直立管におけるひだ、刻印等によって固定される。この解決法は、実際問題としてベストであった。
【0003】
更に米国特許第4245826号(U.S. patent 4 245 826、ドイツ実用新案第 76 23 238)から原則的に等しい可調長さの支柱が公知であり、そこにおいては直立管の下端が半径方向内側に向かって曲げられ、ボトムプレートがこの端部に置かれている。直立管に形成されたひだは、ボトムプレートの上側に面した保護手段として供される。
【0004】
本発明の目的はそれぞれ一般的タイプの支柱と直立管を具現化することにあり、その結果、高い安定性を呈する一方、直立管は特に構造上簡単で非常に容易に製造される。
【0005】
【課題を解決するための手段】
本発明によれば、この目的は、一般的タイプの可調長さの支柱において請求項1の特徴部分における特徴的構成によって、及び請求項5の前文に従う直立管においてその特徴部分の特徴的構成によって達成される。
【0006】
発明に従うやり方のために、更に別の操作によってひだ等を用い固定しなければならない特別なボトムプレートの必要性がもはやない。ボトム構造の安定性は、非常に高く、その結果、ピストンロッドと比較して、たとえ直立管がボトム近傍において又はボトムに付けられるべきベアリング近傍において非常に大きくとも、長さ調整要素のピストンロッドが信頼性高く保持されることとなる。
【0007】
更に有利な実施態様は、従属の請求項から明らかとなろう。
【0008】
【実施例】
本発明の詳細は、図面に関連した例示的な具体例の以下の記述から明らかとなろう。
【0009】
図に示された椅子の支柱は直立管1を有し、これに空気作用の、又は水/空気作用のピストンシリンダ調節要素の形態をした可調長さのガススプリングが配設されている。直立管1とガススプリング2は共通の長手方向中央軸線3を有する。
【0010】
ガススプリング2の外側ハウジング4はガイドブッシュ5内に軸線3の方向に変位可能に支持され、ガイドブッシュは一端6、即ち、図面における直立管1の上方端に配設される。ガススプリング2のこの外側ハウジング4は、スプリング自身のハウジングであるか、ハウジングを取り巻く保護管のいずれかであってもよい。
【0011】
ガススプリングのハウジング4からピストンロッド7が突き出ており、これは軸線3方向において軸ローラベアリング8を介して直立管1のボトムプレート9に対して支持されている。ボトムプレート9は第一端部6と反対側の直立管1の端部10に位置するが、この端部10は図面において底側に示される。軸ローラベアリング8を貫くピストンロッド7の突出部11は、ボトムプレート9の軸線3と同心状に表された開口部12を通って延在する。シム13とスプリング固定リング14が突出部11をボトムプレート9の下側へ向かって引き出すことに抗して固定する。開口部12の径は突出部11の径よりも大きい。この種の締結でガススプリング2は直立管1に対して回転可能である。突出部11と開口部12の間の半径方向の遊び15のためにガススプリングは直立管1に対して僅かだけ傾き、そしてガイドブッシュ5内においては斜めにならずに案内される。最後にピストンロッド7とともにガススプリングは、作動ピン16の作動によってガススプリング2の長手方向の調整に関してガススプリング2のハウジング4が直立管1に対して出入りするように、軸線3方向に直立管に対して取り付けられる。作動ピン16はピストンロッド7と反対側のガススプリング2のハウジング4の端部に位置する。椅子座面又はテーブル上面が同様にこれに固定される。
【0012】
端部10と隣接して、直立管1は当該端部に向かって僅かに円錐状に窄まったコーン部分17を有し、これによって直立管1を複脚椅子ベース等の対応する円錐ブッシュに取り付けることが可能となる。
【0013】
主に椅子支柱として用いられるがテーブル等の支柱としても用いられるここまでに記載された支柱は、一般的に公知で市販されており、例えばドイツ特許第1931012号明細書(German patent 19 31 012、米国特許第 3 711 054号に対応する)及びヨーロッパ特許第133524号公報(EP 0 133 524 B1、米国特許第 4 979 718号に対応する)又はヨーロッパ特許第366889号公報(EP 0 366 889 B1、米国特許第 4 969 619号に対応する)に記載され図示されている。
【0014】
直立管1の全ボトム9は当該管と一体的に形成され、即ち、当該管の変形によって実際の直立管から作られている。コーン部分17に下方部分18が続き、この下方部分はコーン部分に対して収縮され、この部分にボトム9は形成されている。ボトム9は直立管1の内側に向かって開放した溝19を有し、軸線3に向かう方向において、当該溝19に実質的に平坦な環状部分20が続き、この環状部分は軸線3に対し半径方向に延在し、軸ローラベアリング8に対する支持表面として供され、その中の空間部が開口部12となる。
【0015】
図面から認められるように、溝19は断面がほぼ半円状で、鋭いエッジ部を有しない。溝19が環状部分20に至る接合点21は同様に丸みを帯びていて、言い換えれば、鋭い角部をつけられていない。環状部分20に至る溝19の穏やかな移行部を実現するために、環状部分20に向いた溝19の脇腹部22は環状部分20に向かって明らかに偏らされ、理想的な半円断面領域から外れている
【0016】
直立管1の部分18の内径Dは図面から認められるようにピストンロッド7の径dよりも多重的乃至倍数的に大きい。同様にローラベアリング8の径d’は内径Dよりはっきりと小さい。軸線3に対して半径方向の溝19の平均幅aは30〜50mmの範囲となる。ピストンロッド7の径dはほぼ10mmである。20〜30mmの範囲が径d’に当てはまる。
【0017】
図1に示されたように、ボトム9から下方へ突き出しシム13とスプリング固定リング14からなる突出部11の部分は、溝19が環状部分20を越えて下方に向かって突き出ているので、ボトム9においていわば陥没の反対状態(countersunk)にある。スプリング固定リング14はそれ故、溝19の範囲内で保護される。厚パイルのカーペットによって取り除かれることがなく、ユーザーが足で直立管1の下方部分に触れる際に怪我をする危険がない。

BACKGROUND OF THE INVENTION
The present invention preamble (preamble, so-called Oite portion) of claim 1 adjustable length strut according to, and the preamble (preamble, so-called Oite portion) of claim 5 relates standpipe according to.
[0002]
[Prior art and problems to be solved by the invention]
The seed concept of adjustable length struts is known from EP 366889 (corresponding to EP 0 366 889 B1, US Pat. No. 4,969,619). In these known struts, the lower end of the upright tube is bent inward, has a substantially semicircular cross-sectional area, and forms a groove opening in the direction of the longitudinal central axis and toward the inner side of the upright tube. To do. The bottom plate is supported on the front portion of the lower end. The front is spaced from the inner wall of the upright tube. The bottom plate is fixed to the upper end of the upright pipe by folds, engravings, or the like in the upright pipe. This solution was the best in practice.
[0003]
Furthermore, in principle US Pat. No. 4,245,826 (US Pat. No. 4,245,826, German Utility Model 76 23 238) is known in principle of struts of adjustable length, in which the lower end of the upright pipe faces radially inward. The bottom plate is placed at this end. The pleats formed in the upright pipe serve as a protective means facing the upper side of the bottom plate.
[0004]
The object of the present invention is to embody each of the general types of struts and upright tubes, so that they exhibit high stability, while the upright tubes are particularly simple in structure and very easy to manufacture.
[0005]
[Means for Solving the Problems]
According to the invention, this object is achieved by the characteristic configuration in the characterizing portion of claim 1 in a general type of adjustable length strut and in the upright tube according to the preamble of claim 5 Achieved by:
[0006]
Due to the manner in accordance with the invention, there is no longer a need for a special bottom plate that must be secured with folds or the like by further operations. The stability of the bottom structure is very high, so that the piston rod of the length adjustment element is very small compared to the piston rod, even if the upright tube is very large near the bottom or near the bearing to be attached to the bottom. It will be kept highly reliable.
[0007]
Further advantageous embodiments will become apparent from the dependent claims.
[0008]
【Example】
Details of the invention will become apparent from the following description of illustrative embodiments in connection with the drawings.
[0009]
The chair post shown in the figure has an upright tube 1 on which is arranged an adjustable length gas spring in the form of a pneumatic or water / pneumatic piston cylinder adjustment element. The upright tube 1 and the gas spring 2 have a common longitudinal central axis 3.
[0010]
The outer housing 4 of the gas spring 2 is supported in the guide bush 5 so as to be displaceable in the direction of the axis 3, and the guide bush is disposed at one end 6, that is, the upper end of the upright pipe 1 in the drawing. This outer housing 4 of the gas spring 2 can be either the spring's own housing or a protective tube surrounding the housing.
[0011]
A piston rod 7 protrudes from the housing 4 of the gas spring, and is supported on the bottom plate 9 of the upright pipe 1 via an axial roller bearing 8 in the direction of the axis 3. The bottom plate 9 is located at the end 10 of the upright tube 1 opposite the first end 6, which is shown on the bottom side in the drawing. The protrusion 11 of the piston rod 7 penetrating the shaft roller bearing 8 extends through an opening 12 that is concentric with the axis 3 of the bottom plate 9. The shim 13 and the spring fixing ring 14 fix the protruding portion 11 against pulling out toward the lower side of the bottom plate 9. The diameter of the opening 12 is larger than the diameter of the protrusion 11. With this type of fastening, the gas spring 2 can rotate relative to the upright pipe 1. Due to the radial play 15 between the projection 11 and the opening 12, the gas spring is slightly inclined with respect to the upright tube 1 and is guided in the guide bush 5 without being inclined. Finally, together with the piston rod 7, the gas spring is formed into an upright pipe in the direction of the axis 3 so that the housing 4 of the gas spring 2 moves in and out of the upright pipe 1 with respect to the longitudinal adjustment of the gas spring 2 by the operation of the operating pin 16. It is attached to. The operating pin 16 is located at the end of the housing 4 of the gas spring 2 opposite to the piston rod 7. The chair seat surface or table top surface is fixed to this as well.
[0012]
Adjacent to the end 10, the upright tube 1 has a cone portion 17 that is slightly conically narrowed toward the end, thereby allowing the upright tube 1 to be a corresponding conical bushing such as a multi-leg chair base. It can be attached.
[0013]
The struts described so far, which are mainly used as chair struts but are also used as struts for tables etc., are generally known and commercially available, for example German patent 1931 012 (German patent 19 31 012, US Pat. No. 3,711,054) and European Patent No. 133524 (corresponding to EP 0 133 524 B1, US Pat. No. 4,979 718) or European Patent No. 366889 (EP 0 366 889 B1, (Corresponding to US Pat. No. 4,969,619) and illustrated.
[0014]
All the bottoms 9 of the upright tube 1 are formed integrally with the tube, i.e. made from an actual upright tube by deformation of the tube. The cone portion 17 is followed by a lower portion 18 which is shrunk with respect to the cone portion, in which a bottom 9 is formed. The bottom 9 has a groove 19 that is open toward the inside of the upright tube 1, and in the direction towards the axis 3, the groove 19 is followed by a substantially flat annular part 20, which has a radius relative to the axis 3. It extends in the direction and serves as a support surface for the shaft roller bearing 8 , and the space portion therein becomes the opening 12.
[0015]
As can be seen from the drawing, the groove 19 is substantially semicircular in cross section and has no sharp edges. The junction 21 where the groove 19 reaches the annular part 20 is similarly rounded, in other words not sharpened. In order to achieve a gentle transition of the groove 19 leading to the annular part 20, the flank 22 of the groove 19 facing the annular part 20 is clearly biased towards the annular part 20 from the ideal semicircular cross-sectional area. It is off .
[0016]
The inner diameter D of the portion 18 of the upright pipe 1 is multiple or multiple larger than the diameter d of the piston rod 7 as can be seen from the drawing. Similarly, the diameter d ′ of the roller bearing 8 is clearly smaller than the inner diameter D. The average width a of the grooves 19 in the radial direction with respect to the axis 3 is in the range of 30 to 50 mm. The diameter d of the piston rod 7 is approximately 10 mm . The range of 20-30 mm applies to the diameter d ′.
[0017]
As shown in FIG. 1, the protruding portion 11 including the shim 13 and the spring fixing ring 14 protrudes downward from the bottom 9, and the groove 19 protrudes downward beyond the annular portion 20. At 9, it is in a countersunk state of depression. The spring retaining ring 14 is therefore protected within the groove 19. It is not removed by the thick pile carpet and there is no risk of injury when the user touches the lower part of the upright tube 1 with his foot.
