Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for a passenger conveyor such as an escalator and an electric road. 2. Description of the Related Art Conventionally, an example of providing a safety device on a skirt guard of a balustrade and an inner deck cover disposed on a side of the tread plate and its side is disclosed in, for example, Japanese Patent Publication No. 55-18235. As described above, a configuration is known in which a safety piece such as a brush protruding from a balustrade base toward a tread side is provided in the vicinity of a boarding / alighting floor. [0003] Recently, with the development of public transportation, measures to enhance the safety of passenger conveyors, and the introduction of foreign substances such as tickets, commuter passes, and boarding passes into the machine, have been increasing. Intrusion (loss) prevention measures are required. This kind of request is regarded as important for applications with strong publicity, high safety,
There is a need for a safety device that does not allow foreign substances to enter and that is truly oriented toward passenger protection. However, the above-mentioned known example is a safety device limited only to the vicinity of the floor of the boarding and getting off, and could not achieve sufficient passenger protection. [0004] It is an object of the present invention to provide a safety device for a passenger conveyor which is improved in safety between a tread and a skirt guard on which a passenger rides and a skirt guard, prevents foreign substances from entering, and is excellent in shape. [0005] In order to achieve the above object, a safety device of the present invention is provided with a base having a trapezoidal cross section of a top surface, two slopes, and a bottom surface, and a base planted on the top surface. A safety device consisting of a brush body is fixed to a skirt guard or an inner deck cover, and the brush body protrudes toward the tread side,
It is characterized in that it is configured to be elongated along the moving direction of the tread plate. Due to the presence of the safety device having the above-described structure, it is difficult to visually and physically approach the gap between the tread and the skirt guard to improve safety, while foreign matters such as tickets and boarding tickets do not enter. A multi-purpose effect can be exhibited. Further, a safety device excellent in safety and aesthetic appearance can be obtained. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to an escalator shown in FIGS. FIG. 1 is a perspective view showing a main part of the escalator 1, and FIG. 2 is a sectional view taken along line MM of FIG. In the figure, an escalator 1 is composed of a plurality of connected treadboards 2 circulating and moving, a landing floor 3 reaching the treadboards 2, a skirt guard 4 arranged on both sides of the treadboards 2, an inner deck cover 5, a balustrade 7 composed of a balustrade panel 6, and the like. It has. In general, there is a gap G of about 5 mm between the tread 2 and the skirt guard 4, and injuries such as personal injury, tickets, commuter pass, boarding pass, etc., in which shoes or clothes are drawn into the gap G, enter. And it is known that it may be lost or cause a mechanical failure. For this reason, in the above-mentioned known example, a safety piece such as a brush protruding from the balustrade base toward the tread plate is limited to only the vicinity of the getting on / off floor 3. In order to avoid the safety effect in the range (the tread running path), the present invention adds an improvement measure of the illustrated configuration. One of the remedies is characterized in the longitudinal direction of the safety device. The safety devices 8 and 9 are arranged on the entire travel path of the tread 2 from one floor 3 to the other floor (not shown). In addition, all parts are configured to exhibit a safety effect and a foreign matter intrusion prevention effect described later. Two of the remedies are characterized in the height direction of the safety device. The safety device 8 is fixed to the skirt guard 4 below the inner deck cover 5 and the safety device 9 is directly fixed to the inner deck cover 5. And the height H usually near the floor 3
At the position of height h on the ramp.
h, the safety devices 8, 9 and the tread plate 2 are arranged with a step as shown in the drawing so that the vertical distance between them is as equal as possible.
That is, the effect of preventing foreign matter from entering the surface is equally devised. Three of the remedies are characterized by the shape and configuration of the safety devices 8 and 9, and the safety device 8 is provided with a top surface 8a and a two-side slope 8.
b, 8c and a base 8A having a trapezoidal cross section of a bottom surface 8d, a brush body 8B of a fixed length planted on the top surface 8a and a bonding agent 8
C. Similarly, the safety device 9 has a top surface 9a.
And a base 9A having a trapezoidal cross section of the two slopes 9b and 9c and the bottom surface 9d, a brush body 9B of a fixed length planted on the top surface, and a bonding agent 9C. Then, the safety devices 8 and 9 are fixed to the skirt guard 4 and the inner deck cover 5 with bonding agents 8C and 9C, and the brush bodies 8B and 9B protrude toward the tread plate 2 in the moving direction of the tread plate 2. It is arranged long and narrow along. Here, the slopes 8b and 9b on one side have an aesthetic effect that matches the design of the inner deck cover 5 and the slope 8 on one side.
C and 9C have an effect that the shoes and the like are guided as shown by an arrow X so that the shoes and the like do not get caught between the bases 8A and 9A when the tread plate 2 performs the operation of enlarging the vertical step. There is a configuration to demonstrate. The safety devices 8 and 9 having the above-described structure visually and physically cover the gap G, thereby improving safety by preventing the human body from approaching this portion and preventing foreign substances from entering. It is desirable that the color tone of the constituent devices of the safety devices 8 and 9 be different from that of the tread 1 so as to have a color tone alert effect. Although the escalator tread 2 has been described above, a similar effect can be obtained in the case of an electric road by adopting a similar configuration. As described above, according to the present invention, the safety between the tread on which the passenger rides and the skirt guard is improved, the intrusion of foreign substances is prevented, and the passenger conveyor safety device is excellent in shape. Can be provided.
