Description of the Related Art A passenger conveyor, typically a step of an escalator, has, for example, a stepped semicircular protrusion on a step that abuts a step shaft as disclosed in Japanese Patent Laid-Open No. 5-85689. When contacting the step shaft, a semi-circular projecting portion that comes into contact with the projecting portion is provided on the left and right so that the step shaft is pivotally supported from below and the step shaft is gripped. The step shaft is engraved, and two annular nuts having female threads engraved on the inner circumference of the step shaft are passed through on both sides, and the annular nut and the projecting portion can be fastened to each other. The structure is fixed to the shaft.

環形ナットの交換作業が難しいという問題点があった。In the above-mentioned prior art, when performing the fastening work of the annular nut, it is troublesome because the worker has to enter the inside of the frame structure of the traveling path of the escalator, and it is troublesome. When inspecting the escalator inside the body, one step must be completely removed, which requires a great deal of work. Furthermore, when the ring nut is damaged due to repeated tightening and removal of the ring nut, the step shaft with rollers fitted on both ends penetrates through it, making it difficult to replace the damaged ring nut. There was a problem.

Further, as shown in FIG. 2, the link mechanism 8 is supported by a spring (not shown) so that the support rod 81 extends laterally and is fitted into the support hole 65 of the slant frame body 64, and the tread plate 6 is inserted through the lock 7.
1'is fixedly supported on an inspection step 6 '. Further, the bolt 9 is tightened and fixed to the bearing 51 through a mounting hole (not shown) formed in the horizontal frame 63, so that the inspection step 6 ′ can be rotated by the step chain 5 through the bearing 51. It is supposed to be connected to. In this way, the inspection step 6'can be used in the same manner as the other normal steps 6 at normal times.

構造体内のエスカレーターの点検を行う。Next, a method of using the escalator for inspection and repair within the frame structure (not shown) on the traveling path of the escalator will be described. First, when the worker inserts the key 11 into the keyhole of the lock 7 provided on the tread 61 'and rotates it, the support rod 81 is pulled inward against the elastic force of the spring of the link mechanism 8. Since it is moved, the support rod 81 is dropped from the inside of the support hole 65 of the slant frame body 64, and the tread plate 61 'is released from the engaged state with the inspection step 6'. Next, when the operator holds the key 11 and lifts it together with the tread 61 ', the tread 61' can be removed from the inspection step 6'and removed as shown in FIG. A possible opening is formed. Therefore, the worker observes the inside through this opening and inspects the escalator in the frame structure.

行うことができる。If necessary, the user can put his or her hand in the opening, insert the bolt fastening tool 10 into the insertion holes 66 formed at both ends of the horizontal frame 63, and loosen the bolt 9 to remove it. The horizontal frame 63 is released from the bearing 51 of the step chain 5, and the inspection step 6 ′ is removed from the step chain 5. As a result, a large opening through which a worker can enter is formed. The worker enters the opening to inspect and repair the escalator in the frame structure. Thus, in this example, the escalator in the frame structure can be inspected by removing only the step plate 61 'from the inspection step 6', and further, if necessary, the inspection step 6'can be easily performed. Since it can be removed from the step chain 5, inspection and repair work can be performed within the frame structure of the traveling path of the escalator by a simple and waste-free work according to the situation at that time.

挿入孔６６の上部に突出するように設定されている。FIG. 8 is a partially enlarged vertical sectional view of a mounting portion of a step chain for inspection to a bearing of a step chain for inspection according to a modification of this specific example. In the figure, 91 is the head of the bolt 9. The same reference numerals indicate that they can be regarded as the same parts or the same parts as those in the above-described specific example. In this modified example, when the bolt 9 is in a completely tightened state, the head 91 of the bolt 9 does not project above the insertion hole 66 of the horizontal frame 63 as shown in FIG. When completely tightened,
As shown in FIG. 7B, the head portion 91 is set so as to project above the insertion hole 66 of the horizontal frame 63.

7, the tread plate 61 'cannot be completely fixed to the inspection step 6'. Thus, in this modified example, when the bolt 9 is in an incompletely tightened state, the tread 61 'cannot be completely fixed to the inspection step 6', so that the tread 6 '
Whether or not the bolt 9 is in a tightened state can be determined based on whether or not 1'can be completely fixed to the inspection step 6 ', and an error in tightening the bolt 9 can be reliably prevented. Further, even if the bolt 9 is loosened during the operation of the escalator, the head 91 of the loosened bolt 9 comes into contact with the leg 67 of the tread 61 'to prevent further loosening. It is possible to prevent the inspection step 6'from falling off from the step chain 5 therein.

In the figure, as shown in (c), reference numeral 92 is a grooved groove formed around the substantially middle portion of the bolt 9, and 12 is a retaining ring fitted into the grooved portion 92. The outer diameter of the retaining ring 12 is set to be larger than the inner diameter of the insertion hole 66 of the horizontal frame 63. Then, the retaining ring 12 is fitted into the groove 92 of the bolt 9 after the bolt 9 is fastened to the bearing 51 through the insertion hole 66 of the horizontal frame 63. Further, the bolt 9 is loosened with the retaining ring 12 fitted in the groove 92 below the insertion hole 66, and the horizontal frame 6
When 3 is released from the fastened state with the bearing 51 of the step chain 5, the lower end thereof is set to a height such that it does not escape from the upper surface of the flat surface portion that forms the mounting surface of the horizontal frame 63 with the bearing 51.

3 does not come out from the insertion hole 66 of the
When tightening or loosening the
3 can be prevented from falling off from the insertion hole 66. Further, when the tread 61 'is fixed to the inspection step 6', if the uppermost end face of the lateral frame 63 is set to abut against the lower surface of the leg 67 of the tread 61 ', the bolt 9 will not be tightened properly. At this time, the tread 61 'cannot be completely fixed to the inspection step 6', so that a mistake in tightening the bolt 9 can be reliably prevented.

きる。According to the second aspect of the invention, the frame of the step is fastened with a bolt to the receiving member rotatably connected to the step chain, and when the bolt is tightly attached, the head of the bolt is fastened. Does not contact the lower part of the tread or the member integrated with the tread, and when the bolt is loosely attached, the head of the bolt contacts the lower part of the tread or the member integrated with the tread so that the bolt Since the mounting height is set, it is possible to determine whether or not there is a defective bolt tightening simply by checking the mounting state of the tread to the frame body, so that it is possible to reliably prevent a mistake in tightening the bolt.

のを防止することができる。According to the third aspect of the present invention, the bolt is tightened.
The attachment work can be reliably prevented, and the fitting member is fitted to the neck portion of the bolt that connects the receiving member rotatably connected to the step chain and the frame of the step, and the bolt is loosened and received. When the fastening state between the member and the frame is released, the fitting member contacts the locking member integrated with the frame of the step to prevent the bolt from deviating from the engaged state with the frame. Therefore, it is possible to prevent the bolt from falling out of the engaging portion of the frame during the tightening or loosening work of the bolt.
