そのマンコンベヤの安全装置の従来例を第鳳図に示す。An example of a conventional safety device for a passenger conveyor is shown in Figure 1.

締め付けて取り付けている。As a safety device on the back side of the skirt guard 5,
A detection switch 6 such as a limit switch is disposed with a predetermined gap G between them. That is, in the space below the inner deck plate 3 and the outer deck plate 4 at the bottom of the parapet, an angle-shaped support 9 is fastened with bolts 10 and nuts 11 with a gap adjustment piece 8 interposed on the fixed frame 7, and this support is A detection switch 6 is attached to the body 9 by tightening it with a bolt 12 and a nut 13.

によりマンコンベアの運転を停止して安全を図るように
なっている。When a foreign object such as a passenger's footwear is caught in the small gap S between the step 1 and the skirt guard 5, and the skirt guard 5 is bent by the pressure of the foreign object and displaced by a predetermined amount toward the back side, A detection switch 6 arranged at a distance G on the back side is pressed to perform a detection operation, and the detection signal is used to stop the operation of the passenger conveyor for safety.
ここで、前記間隔Ｇは、ステップ１とスカートガード５

撓み変位量を考慮した寸法距離に設定管理する。Here, the distance G is between the step 1 and the skirt guard 5.
The amount of deflection displacement of the skirt guard 5 due to the predetermined pressure of the foreign object is determined so that the detection switch 6 operates to detect the foreign object caught in the small gap S between the Manage settings to the considered dimensional distance.

。The setting management of this interval G is carried out by adjusting the above-mentioned gap at each execution site, since the distance relationship between the fixed frame 7 and the skirt guard 5 differs from one conveyor table to another or from place to place due to manufacturing and assembly errors. By increasing or decreasing the number of pieces 8, the detection switch 6 can be adjusted to move toward or away from the front of the skirt guard 5.

で、多くの労力と時間を要する問題があった。(Problem to be Solved by the Invention) By the way, in the conventional safety device for a passenger conveyor described above, the distance G between the back side of the skirt guard 5 and the detection switch 6 is adjusted by adjusting the distance G between the fixed frame 7 and the support body 9. This is done by increasing or decreasing the number of intervening gap adjustment pieces 8, so at that time it is necessary to loosen and retighten the bolts 10 and nuts 11. Work efficiency is poor because the area is narrow. Moreover, in order to finally confirm the detection operation of the detection switch 6 based on the deflection displacement of the skirt guard 5 at a predetermined pressure, the distance G is adjusted and the skirt guard 5 is installed.
If the detection operating pressure is measured in this state, the work of removing the skirt guard 5 for readjustment is repeated, which poses a problem that requires a lot of labor and time.

確実となる。Also in this third embodiment, the detection switch 6 is installed via the switch support mechanism 40 on the back side of the skirt guard 5, and after the skirt guard 5 is installed, the adjustment operation is performed from the front side of the skirt guard 5. A tool 27 such as a screwdriver is inserted through the hole 26, and the advance/retreat adjusting bolt 45 is turned to the right or left, and the pressing action thereof causes the rotating member 43 to rotate about the hinge 42. As a result, the detection switch 6 attached to the rotating member 33 moves in the direction toward and away from the back surface of the skirt guard 5 together with the rotating member 33, and the distance between the detection switch 6 and the back surface of the skirt guard 5 increases. The distance G can be adjusted easily and easily. After adjustment, use a tool 27' such as a screwdriver through the other adjustment operation hole 26'.
, and tighten the fixing bolt 46 to fix the rotating member 43. This further simplifies and ensures layer adjustment work.

付調整作業の能率化か図れる。Since the safety device for the passenger conveyor of the present invention is configured as described above, with the skirt guard attached, a tool such as a screwdriver is inserted from the front side through the adjustment operation hole and the switch support mechanism is operated to operate the detection switch. Since the skirt guard can be moved in the direction toward and away from the rear surface of the skirt guard, it is possible to check the detection operation of the detection switch by the deflection displacement of the skirt guard under a predetermined pressure, without having to perform troublesome work such as attaching and detaching the skirt guard. The distance between the skirt guard and the back surface can be easily and easily adjusted, making the installation and adjustment work of the detection switch more efficient.

とを特徴とするマンコンベアの安全装置。In a passenger conveyor such as an escalator that has a small gap and skirt guards on both sides of a rotating step, when a foreign object is caught between the step and the skirt guard and the skirt guard is displaced, the skirt guard is disposed on the back side. In a safety device for a passenger conveyor in which a detection switch installed detects and operates to stop the operation of the passenger conveyor, a hole for adjustment operation is drilled in the skirt guard, and a tool is inserted from the surface side of the skirt guard through this operation hole. 1. A safety device for a passenger conveyor, characterized in that a switch support mechanism is provided that is movable when operated and can be adjusted to move the detection switch in a direction toward and away from the back surface of a skirt guard.
