Description

本発明は、エスカレータや動く歩道などのマンコンベアにおけるステップの改良に関するものである。   The present invention relates to a step improvement in a man conveyor such as an escalator or a moving sidewalk.

一般的に良く知られ使用されているエスカレータは、図４に示すようにステップ１が無端状に連結されて循環移動され、乗客はこのステップ１上に乗って異なる階床間を搬送されるものである。
特開２０００−３４４４５５号公報 As shown in FIG. 4, a generally well-known and used escalator is one in which step 1 is connected endlessly and circulated, and passengers ride on this step 1 and are transported between different floors. It is.
JP 2000-344455 A

ところで、このステップ１は図５に示すようにステップチェン２及び前輪３が取付けられている軸４にスリーブ５を介して取付けられるが、特開２０００−３４４４５５号公報のように、この軸４が回動自在に設けられるタイプ（ステップが軸と一体となって回転する）と、固定されるタイプの二種類に分かれている。   By the way, this step 1 is attached to the shaft 4 to which the step chain 2 and the front wheel 3 are attached via the sleeve 5 as shown in FIG. 5, but this shaft 4 is attached to the shaft 4 as disclosed in Japanese Patent Laid-Open No. 2000-344455. There are two types: a type that can be rotated (the step rotates integrally with the shaft) and a type that is fixed.

特に後者の場合は、発展途上国で製作する場合でも、市販品の中から個々の部品を自由に入手することができるため、極めて低価格のステップを得ることができ、汎用性の高いエスカレータを手に入れることができる。。 Especially in the latter case, even when manufacturing in developing countries, individual parts can be freely obtained from commercial products, so it is possible to obtain extremely low-cost steps, and a highly versatile escalator. You can get it. .

ここで、軸４が回動しないタイプのものでは、ステップ１とともにスリープ５が自由に回転し、軸４の長さ方向に沿って自由にスライドできなければならないが、この時、軸４とスリーブ５の嵌合がゆる過ぎるとステップ１が回転する時に騒音が発生したり、スリーブ５にヘタリが生じるため、スリーブ５には厳しい公差管理が求められるとともに、ステップ１の位置を決めてその位置を保持できなければならない。従来、磨耗したスリーブ５の交換の際には、ステップチェン２や前輪３を一旦取り外さなければならないなどの欠点があった。 Here, in the type in which the shaft 4 does not rotate, the sleep 5 must freely rotate with the step 1 and should be able to slide freely along the length direction of the shaft 4. If the fitting of 5 is too loose, noise will be generated when the step 1 rotates, and the sleeve 5 will be crushed. Therefore, the sleeve 5 is required to have strict tolerance control, and the position of the step 1 is determined and determined. Must be able to hold. Conventionally, when the worn sleeve 5 is replaced, the step chain 2 and the front wheel 3 have to be removed once.

本発明は、ステップチェンに固定されたステップ取付用軸の所定位置にスリーブを介してステップが回動自在に設けられるものにおいて、スリーブをスリット付きとし、スリーブの一部には外周に突部を有し、該突部に接する面にはクランプを備え、前記スリーブにおける前記突部の反対面には第２のクランプを備え、
前記ステップ取付用軸の両端部及び前記ステップチェンに固定されたピンの双方には穴が空けられ、前記穴どうしをクリップで連結したものである。
In the present invention, a step is rotatably provided at a predetermined position of a step mounting shaft fixed to a step chain via a sleeve. The sleeve is provided with a slit, and a protrusion is provided on the outer periphery of a part of the sleeve. Having a clamp on the surface in contact with the protrusion, and a second clamp on the surface of the sleeve opposite to the protrusion,
Both ends of the step mounting shaft and pins fixed to the step chain have holes, and the holes are connected by clips .

本発明は、クランプを取り外して、スリーブ５を軸４に沿ってスライドさせると、ステップを簡単に取外すことができ、このスリーブ自体もスリット入りのため、このスリットを広げれば簡単に軸４から取外せて交換を行うことができる。   In the present invention, when the clamp is removed and the sleeve 5 is slid along the shaft 4, the step can be easily removed. Since the sleeve itself also has a slit, it can be easily removed from the shaft 4 by widening the slit. It can be removed and exchanged.

本発明は、スリット付きのスリーブの一部外周に突部を備え、この突部に面してクランプを取り付けるようにすれば、決められた位置にステップを保持することが簡単にできるものである。   According to the present invention, if a protrusion is provided on a part of the outer periphery of a sleeve with a slit and a clamp is attached so as to face the protrusion, the step can be easily held at a predetermined position. .

以下、本発明の一実施例について、図面を用いて説明する。図１は本発明の一実施例を示す全体斜視図、図２はステップの平面図、図３は図２のＡ部拡大図である。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 is an overall perspective view showing an embodiment of the present invention, FIG. 2 is a plan view of steps, and FIG. 3 is an enlarged view of a portion A in FIG.

図中、１０は本発明に係るスリーブで、スリット１０ａが入っており、一部外周には突部１０ｂを有している。このスリット１０ａを広げると軸４に極めて簡単に取付け・取外しが自由に行えるものである。そして、このスリーブ１０を介してステップ１が軸４に対し回動自在に設けられる。この軸４は回転しない構造になっている。即ち、ステップチェン２にはピン６が固定され、このピン６には穴６ａを有し、軸４の両端にも穴４ａを備え、クリップ７によりこの穴４ａと穴６ａとを連結してステップチェン２に軸４を設けている。   In the figure, reference numeral 10 denotes a sleeve according to the present invention, which has a slit 10a, and has a protrusion 10b on a part of its outer periphery. When the slit 10a is widened, the shaft 4 can be easily attached and detached freely. The step 1 is provided so as to be rotatable with respect to the shaft 4 through the sleeve 10. The shaft 4 has a structure that does not rotate. That is, a pin 6 is fixed to the step chain 2, the pin 6 has a hole 6a, and both ends of the shaft 4 are provided with a hole 4a. The clip 7 connects the hole 4a and the hole 6a to form a step. A shaft 4 is provided in the chain 2.

１１はこのスリーブ１０を軸４に保持するためのクランプで、突部１０ｂに接するように軸４に取付けられ、所定位置でのスリーブ１０の保持を行うものである。一方、１２はスリーブ１０を軸４から取外す際に後々、目印とするためのクランプで、スリーブ１０における反突部側に設けられる。実施例では、スリーブ１０の突部１０ｂはステップ１の中央寄りに配置される。 Reference numeral 11 denotes a clamp for holding the sleeve 10 on the shaft 4, which is attached to the shaft 4 so as to be in contact with the protrusion 10b, and holds the sleeve 10 at a predetermined position. On the other hand, 12 is a clamp that serves as a mark later when the sleeve 10 is removed from the shaft 4, and is provided on the side of the sleeve 10 opposite to the protruding portion. In the embodiment, the protrusion 10 b of the sleeve 10 is arranged near the center of Step 1.

次に、磨耗したスリーブ１０を交換する場合の手順について説明する。
先ず、スリーブ１０の外側側面（反突部側）に接するようにクランプ１２を軸４に取付ける。次に、クランプ１１を取外し、スリーブ１０を軸４に沿ってスライドさせステップ１の保持部１ａから抜き取りステップ１を解放する。次に、このスリーブ１０のスリット１０ａを広げて軸４からスリーブ１０を取外し、その後新しいスリーブ１０と交換する。スリーブ１０を取付ける場合も、スリット１０ａを広げれば簡単に軸４に再度取付けることができる。次に、クランプ１２を目印にしてステップ１を手で保持しながら、ステップ１の保持部１ａの中にスリーブ１０を軸４に沿ってスライドさせて挿入する。最後に、クランプ１１をスリーブ１０の内側側面に合わせて軸４に取付けて、交換作業を完了する。 Next, a procedure for replacing the worn sleeve 10 will be described.
First, the clamp 12 is attached to the shaft 4 so as to be in contact with the outer side surface (opposite side) of the sleeve 10. Next, the clamp 11 is removed, and the sleeve 10 is slid along the shaft 4 to release the step 1 from the holding portion 1a of the step 1. Next, the slit 10a of the sleeve 10 is widened, the sleeve 10 is removed from the shaft 4, and then replaced with a new sleeve 10. Even when the sleeve 10 is attached, it can be easily reattached to the shaft 4 if the slit 10a is widened. Next, the sleeve 10 is slid along the shaft 4 and inserted into the holding portion 1a of step 1 while holding the step 1 by hand with the clamp 12 as a mark. Finally, the clamp 11 is attached to the shaft 4 in alignment with the inner side surface of the sleeve 10 to complete the replacement operation.

以上述べたとおり、本発明に係るスリーブ１０であれば、円筒部の内径・外径寸法の加工誤差をスリット１０ａで吸収できるため、内径・外径の厳しい寸法公差は必要なく、円筒部の肉厚寸法の公差管理のみで済ませられるものである。 As described above, the sleeve 10 according to the present invention can absorb the processing error of the inner and outer diameters of the cylindrical portion with the slit 10a, so that there is no need for strict tolerance of the inner and outer diameters, and the thickness of the cylindrical portion is not necessary. Only the tolerance management of the thickness dimension can be done.

実施例で述べているエスカレータだけでなく、パレットを使用するような動く歩道であっても本発明を採用することは可能である。   The present invention can be adopted not only for the escalator described in the embodiment but also for a moving sidewalk that uses a pallet.
