Description

        The present invention relates to a safety device for an escalator, and is particularly arranged in a wedge-shaped space formed between a moving handrail that moves in an upward direction and a fixing member such as an interior material such as a building ceiling that is close to the moving handrail. The present invention relates to a safety device for an escalator.

        In this type of conventional safety device, a safety guard called a triangular guard plate is placed between a moving handrail that moves in the ascending direction of the escalator and an obstacle (interior material) such as a building ceiling that is close to this moving handrail. A device is provided and measures are taken to prevent accidents due to the heads and necks of passengers who have stepped up to the outside of the handrail. (For example, see Patent Document 1)

Also, there is a means to prevent accidents where the head or neck of a passenger who has stepped over to the outside of the moving handrail is fixed to a triangular plate on a fixing member that is an obstacle such as a building ceiling adjacent to the moving handrail Has been taken. (For example, see Patent Document 2)
JP-A-8-26647 JP2002-37578

        In this type of conventional safety device, the triangular guard plate simply contacts the head of the passenger who has stepped over to the outside of the handrail, and the problem that the danger of pinching the neck cannot be avoided, or this triangular guard plate Risk of incurring an accident in which the head or neck of a passenger is caught between obstacles such as the ceiling of the building where the neck and head of the human body that finally broke close to the handrail and between safety devices In addition, the safety device has a problem of high cost because it is made to order according to the individual building.

        In order to achieve the above object, the present invention provides a safety device for an escalator for transporting passengers, comprising a step installed at an incline between a downstairs and an upstairs floor and a moving handrail. Placed in a wedge-shaped space formed between the adjacent building frame and fixing member such as ceiling mounting material, and adjust by sliding the gap (interval) between the mounting body attached to the fixing member and the main body and the moving handrail In addition, the present invention provides a safety device for an escalator that is configured with a gap adjusting slide plate that avoids a shock when a neck or the like collides with a curved surface and eliminates any pinching of the neck or head.

        As described above, according to the safety device for an escalator according to the present invention, the vertical piece and the waterside piece of the gradient-type mounting body in the shape of a deformed triangular plate in the wedge-shaped space are fixed to the fixing member, and the end face facing the rising direction Is formed on a curved end surface that is bent so as to avoid impact when the human body comes into contact, and when the head or neck of a passenger who has stepped over to the outside of the moving handrail comes into contact with this curved end, Because the force is reversed in the opposite direction to the movement stop of the human body, it can be forcibly reversed on the curved end surface and returned to the moving tread board direction, and as a result, between the building ceiling material and beam and other fixed members close to the moving handrail It is possible to avoid an accident in which the head or neck of the customer is caught.

          The clearance adjustment slide plate is a curved plate shaped to match the curved end surface of the mounting body, and can be slidably fitted to the upper and lower ends of the curved end of the mounting body. The interval between the handrail and the fixing member can be easily adjusted to suit the installation housing.

        Hereinafter, the present invention will be described in detail using an embodiment of a safety device for an escalator according to the present invention (hereinafter simply referred to as a safety device). FIG. 1 is a schematic side view of a safety device according to the present invention mounted in a wedge-shaped space between a downstairs and an upstairs, and FIGS. 2A and 2B are a front view and FIG. FIG. 3 is a schematic perspective view showing a safety device according to the present invention, FIG. 4 is an exploded perspective view showing the configuration of the safety device, and FIGS. 5 and 6 are passenger necks or It is explanatory drawing which shows the condition when a head contacts a safety device.

          That is, the safety device 1 according to the present invention is attached to the fixing member described below as shown in FIG. 1 and FIGS. 2 (a) and 2 (b). It is plate-shaped and formed in a gradient shape, and the material is one or more of metal, transparent, opaque, colored synthetic resin, etc., constituted by means such as molding, processing, screws, adhesives, etc. . 13 is a slide plate for adjusting the gap, 15 is a fixing member, which is composed of a frame or a rafter for holding the ceiling material, a joist of a flooring attachment material, a beam material, and the like, and 16 is an escalator, a fixing member on the floor 15. For example, the wedge-shaped space 19 formed by the beam material and the escalator 16 moving in the ascending direction (upstairs) is installed so as to be closed. That is, the escalator 16 that moves in the ascending direction in FIG. 1 is generally installed with its main body inclined between the lower floor and the upper floor where the height is different, and a moving step 17 and a moving handrail 18 for carrying passengers. And the safety device 1 is arranged and mounted in a wedge-shaped space 19 formed between a fixed member 15 such as a building ceiling on the upper floor near the moving handrail 18.

      More specifically, the safety device 1 includes a mounting body 2 and a slide plate 13 for adjusting a gap. The so-called mounting body 2 has a gradient-shaped deformed triangle as shown in FIGS.
