段チェーン緊張装置を提供することにある。The above-mentioned prior art uses elastic bodies provided on both sides of the sprocket teeth to soften the ri9$ when the link plates tl&t of the chain and the chain mesh with the bottoms of the sprocket teeth. By the way, since the link plate of a chain is usually manufactured by punching out a steel plate, the plate 1g portion of the link plate is not pressed against the drying elastic body, and as a result, the elastic body wears out rapidly. ,
The problem is that the buffering effect disappears in a short period of time, resulting in a short lifespan. Also, with this structure, in addition to the drive and driven sprockets, even tension sprockets that simply take the stretch of the chain can be used with tin rocket teeth. It is assumed that it will be manufactured by machining, and the teeth of this sprocket will be manufactured,
Moreover, since the elastic body is provided, there is a problem that a long manufacturing time is required, and there is a problem that it cannot be put to practical use as a tensioning device for a passenger conveyor. SUMMARY OF THE INVENTION An object of the present invention is to provide a step chain tensioning device for a passenger conveyor that is easy to manufacture and can maintain a cushioning effect for a long period of time.

より達成される。The object of the present invention is to use a disc-shaped foil instead of a sprocket in a step chain tensioning device, and to attach a ring-shaped elastic body to the outer periphery of the foil so as to slightly protrude from the foil. This is achieved by forming the outer diameter of the elastic body such that when the step chain is wound around it, an integral multiple of the pitch angle θ of the step chain is other than 360°.

長期に亘って維持できるのである。As a tensioning device for the step chain, a disk-shaped foil spring is used to tension the step chain with a constant force, thereby applying a constant tension to the step chain wound around the disk-shaped foil spring. Is there an elastic body slightly protruding from the voile on the outer periphery of this foil? The step chain that is wound around the foil when used as a device prevents the chain roller from colliding with the elastic body, thereby preventing unpleasant noise or shaking. In addition, the elastic body attached to the foil is
Since the outer diameter of the step chain is configured such that an integer multiple of the pitch angle θ when the step chain is wound around the elastic body is other than 360°, the chain of the step is wound around the foil and the elastic body. The position of the elastic body that the chain i''-5■,'-et,,l-ra hits when the wheel rotates once is always a critical part. Does it eliminate the troublesome manufacture of sprockets without compromising the cushioning effect, and evens out the wear of the elastic body to achieve a good cushioning effect?
It can be maintained for a long period of time.

とができる。In such a configuration, when the passenger conveyor is operated, the step chain 4 is driven by the drive sprocket 5 and runs endlessly between the step chain 4 and the tensioning gear #6. The step chain 4 has a foil 8 and a spring 14. rod 1
3 provides tension, and a certain tension is applied to ensure smooth operation. An elastic body 9 is fitted around the outer periphery of the foil 8, and the roller 18 of the step chain 4 cushions the impact when the chain is caught, thereby reducing unpleasant noise and vibration. This can be prevented from occurring. In addition, the step chain 40 has a roller 18 due to the relationship between the outer diameter of the elastic body 9 and the pitch angle θ.
The position at which the chain collides with the elastic body 9 is constantly changing so that it hits new positions one after another, so that by the time the roller 19 of the step chain 4 leaves the elastic body 9 and contacts the elastic body 9 again at its original position. There will be enough time. This means that the number of times that the elastic body 9 has to repeatedly support the roller 18 of the step chain 4 at a specific position is greatly reduced, and the elastic body 9 can have a very long life. be. Further, when the elastic body 9 reaches the end of its life due to wear or the like, it is only necessary to replace the elastic body 9, and the maintenance cost of the passenger conveyor can be reduced. In this way, the embodiment of the present invention performs a sufficient function as the tensioning device 6 for the step chain 4, and replaces the part that conventionally required expensive gear cutting with a sprocket with a simple disc-shaped foil. By using an elastic body with a long life span, manufacturing costs can be significantly reduced.
