まず、従来のエスカレータの駆動装置を第１〜
第４図によつて説明する。 First, the conventional escalator drive device is
This will be explained with reference to FIG.

する。 In the figure, 1 is the main frame of the escalator, 2 is a step rail placed on this and guides the steps 3, 4 is a step chain consisting of a toothed link 5 to which the steps 3 are connected, and 4a is the outgoing side of this. , 4b is the return path side, 5a is the tooth of the toothed link 5, and as shown in FIG. 4, a constriction 5b is provided at the root of the tooth. 6 is a drive machine installed in the main frame 1, 7 is its electric motor, and 8 is the electric motor 7.
9 is a drive chain wheel rotated by this, 10 is a driven chain wheel provided apart from the drive chain wheel 9, and 11 is a three-row chain, and the outer row is a driving chain which is wound around the driving chain wheel 9 and the driven chain wheel 10 and arranged in an endless manner, and 12
is a roller made of a relatively hard elastic material such as polyurethane and arranged in the center row of the chain. In addition,
The driving chain wheel 9 is disposed closer to the upper end of the main frame 1 than the driven chain wheel 10, and the roller 12 is located on the forward path side 4.
a and the return path side 4b, each of which engages with the tooth 5a.

状態に案内する機能を果せばよく鎖車である必要
はない。したがつて、従動鎖車１０の製作及びこ
れの装着のために余計な製造費を要する不具合が
あつた。 That is, when the drive machine 6 is energized, the drive chain 11
moves, and in the linear motion part of this, roller 1
2 engages with the toothed link 5, and the step chain 4 is driven. At this time, in order to prevent the roller 12 from deviating from the toothed link 5, a constriction 5b is provided in the tooth 5a, so that the roller 12 is elastically deformed and engages with the constriction 5b. In such a driving machine 6, the driven chain wheel 10 need not be a chain wheel as long as it simply functions to guide the drive chain 11 into the state shown in FIG. Therefore, there was a problem in that extra manufacturing costs were required for manufacturing and mounting the driven chain wheel 10.
また、踏段鎖４の駆動時には、第２図に示すよ

具合があつた。 Furthermore, when the step chain 4 is driven, the toothed links 5 are connected to each other above the engagement position of both the teeth 5a and the roller 12, as shown in FIG.
A moment in the direction of arrow A shown in FIG. 2 acts on the toothed link 5. Therefore, during upward operation of the escalator, the toothed link 5 on the outbound side 4a is in a position where the end closer to the driving chain wheel 9 is away from it and the end closer to the driven chain wheel 10 is closer to this, that is, it is tilted. Move with posture. Therefore, the roller 12 is attached to the teeth 5a of the toothed link 5 at the end closer to the driven chain wheel 10.
When engaged, the engagement movement path for the tooth 5a largely bites into the end portion of the tooth, causing the roller 12 to be largely elastically deformed and vibrations occurring in the toothed link 5. Then, there was a problem in that this vibration was transmitted to the steps 3 and the riding comfort of the escalator was impaired. Further, since the deformation of the roller 12 at the initial stage of engagement is large and rapid, the life of the roller 12 is shortened.

以下、第５〜第７図によつてこの発明の一実施
例を説明する。 An embodiment of the present invention will be described below with reference to FIGS. 5 to 7.

ストプレンベアリングである。 In the figure, the same reference numerals as those in FIGS. 1 to 4 indicate corresponding parts, and 10 is a guide body having a curved part 10a around which one inverted part of the drive chain 11 is wrapped.
The outer row rollers of the reversing section 1 roll on the surface of the curved section 10a, and are disposed on a fixed section of the drive machine 6 so as to be movable along the direction in which the drive chain 11 is tensioned. 1
3 is a protrusion erected from the fixed part of the driving machine 6; 14;
15 is a bolt loosely inserted into the protrusion 13; 15 is a nut that is screwed into the insertion end of the bolt and presses the guide 10 to hold the bolt 14 on the guide 10; 16;
The bolt 14 is inserted and the protrusion 13 and guide body 10
A buffer body 17 consisting of a compression coil spring disposed between the drive chain 10 and the support body 17 is formed by extending the open end of the curved portion 10a and supports the linearly moving portion of the drive chain 11. Note that 18 is a thrust plane bearing that guides the bolt in the axial direction.
すなわち、駆動鎖１１は駆動鎖車９及び案内体
１０に巻き掛けられて直線運動部分を形成して動

であるので、安価な駆動装置が得られる。 That is, the drive chain 11 is wound around the drive chain wheel 9 and the guide body 10 to form a linear motion part and operate. This guide body 10 can be manufactured at a lower cost than a chain wheel, and can be easily attached to the drive device 6, so that an inexpensive drive device can be obtained.

できる。 Further, since the guide body 10 is displaceably disposed on the drive unit 6 and is biased by the buffer body 16 in the direction in which tension is applied to the drive chain 11, the roller 12 is engaged with the toothed link 5. The impact when doing so is buffered. Therefore, vibration of the toothed link 5 can be reduced and the life of the drive chain 11 can be extended.
また、支持体１７により駆動鎖１１の直線運動
部が凹曲することなく案内されるので円滑な駆動
作用が得られる。これによつてもエスカレータの
乗心地を向上させるこができる。 Further, since the linearly moving portion of the drive chain 11 is guided by the support 17 without being bent concavely, a smooth driving action can be obtained. This also makes it possible to improve the riding comfort of the escalator.

に生じる振動発生等の障害は小さい。 Furthermore, as shown in FIG. 5, the guide body 10 allows the linear movement portion of the drive chain 11 to be aligned with the pitch line of the toothed link 5 at the center of the portion corresponding to the drive chain wheel 9.
In the portion corresponding to the guide body 10, the center is located near the end of the tooth 5a of the toothed link 5. For this reason, when the drive chain 11 is arranged as shown in FIG. 2 of the conventional example, the roller 12 engages with the tooth 5a on the forward path side 4a of the step chain 4 along the locus of line B in FIG. However, the time it takes to reach point C is short and a significant fluctuation force occurs. In contrast, the drive chain 11 in FIG.
Although the engagement action with the tooth 5a is the same on the trajectory of line B in the figure, the time it takes to reach point C is very long, and several rollers are in the middle of entering point C, and the collective force varies. The force is averaged, the vibration applied to the toothed link 5 is reduced, and the life of the roller 12 can be extended. In addition, since the power transmitted by the drive chain 11 on the return path side 4b of the step chain 4 during upward operation of the escalator, or by the drive chain 11 during downward operation of the escalator, vibrations generated at the initial stage when the roller 12 engages with the teeth 5a, etc. The obstacles are small.

とができる駆動装置が得られる。 Note that even if the buffer body 16 in this embodiment is omitted and the guide body 10 is mounted on the drive machine 6 so as to be displaceable along the direction in which tension is applied to the drive chain 11, An inexpensive drive device can be obtained, and a drive device can be obtained in which the tension of the drive chain 11 can be set appropriately.

It is also possible to manufacture this separately from the curved portion 10a and attach it to a fixed body such as the drive machine 6 separately from the guide body 10.

現するものである。 As explained above, the present invention provides an inexpensive escalator by guiding one inverted part of the drive chain, which forms a linear movement part that engages with the teeth of the toothed link of the step chain, by a guide body having a curved part. In addition, since the linearly moving part of the drive chain is supported by a support body, the linearly moving part can be prevented from concavely bending and the riding comfort of the escalator can be improved. In addition, the guide body corresponding part on at least the forward path side of the step chain of the linear movement part of the drive chain is arranged near the end of the tooth of the toothed link to reduce the amount of elastic deformation at the initial stage of the engagement operation of the roller. The present invention provides an escalator drive device that can reduce vibrations, provide a comfortable ride, extend the life of rollers, and reduce maintenance costs.
