Abstract

<P>PROBLEM TO BE SOLVED: To provide a safety device of an escalator for predicting dangers for passengers leaning forward to the vicinity of a triangular protective plate of the escalator. <P>SOLUTION: This escalator has the triangular protective plate 3 positioned outside a handrail of a triangular space part formed of an upper side floor 2 of a building for storing the escalator and a moving handrail 1 of a handrail upper part of the escalator and hung down from the upper side floor of the building, and is obtained by having a notifying device for directly arousing attention to contact persons by arranging a cylindrical bone-conductive loudspeaker 4 in a front part of the triangular protective plate. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a safety device for an escalator that predicts a danger to a passenger who has entered the vicinity of a triangular protective plate of the escalator.

A triangular protective plate is installed in the triangular space formed by the upper floor of the building that houses the escalator and the handrails at the top of the escalator balustrade to alert the passengers who have entered their body into the triangular space. However, there are cases where it is insufficient as an awakening means such as not being aware of contact, and as a means for solving the above problem, a technique for performing attention broadcasting when a photoelectric beam is shielded has been disclosed (for example, patents) Reference 1).
Japanese Patent Laid-Open No. 10-297865

  In the above-mentioned attention broadcasting of the prior art, since it can be heard by passengers other than the person to be alerted without contact, it may not be easy to know whether the alerter is himself or others, and there is a risk of misunderstanding. In addition, there was a problem that it was difficult to hear if there was a sound source such as other information broadcasting such as outdoors or in department stores. An object of the present invention is to provide an escalator safety device that solves the above-described problems and predicts danger to passengers who have entered the vicinity of the escalator's triangular protective plate without being affected by other sound sources only for the person to be alerted. It is in.

  In order to solve the above-mentioned problem, the present invention is located on the outer side of the balustrade of the triangular space portion formed by the upper floor of the building that houses the escalator and the moving handrail of the upper rail of the escalator, and the upper floor of the building In an escalator including a triangular protective plate that is lowered from the above, this is achieved by providing a notifying device that provides a cylindrical bone conduction speaker in the front of the triangular protective plate and directly alerts the contact person.

  In the present invention, when the escalator comes into contact with the cylindrical bone conduction speaker at the front part of the triangular protective plate, only the contact person can be alerted, so that other passengers are not misunderstood.

  In addition, since information can be transmitted directly to the contact person through bone conduction, there is an effect that danger can be accurately predicted by transmitting information without being influenced by the environment such as other sound sources.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an example of the arrangement of the triangular protective plate and the bone conduction speaker in a triangular space formed by an upper floor of a building that houses the escalator according to the present invention and a moving handrail on the balustrade of the escalator. Show. In FIG. 1, 1 is a handrail for the upper part of the balustrade of the escalator, 2 is the upper floor of the building that houses the escalator, 3 is a triangular protective plate that is lowered from the upper floor of the building, and 4 is suspended from the upper floor of the building 1 shows a cylindrical bone conduction speaker.

  First, the passenger gets on the ascending escalator and moves to the upper floor. At this time, if a passenger gets on and the head comes into contact with the triangular protective plate 3, the first contact with the bone conduction speaker 4 is likely to come into contact with the triangular protective plate 3, which is dangerous. Information can be conveyed directly to the contact person by voice. The information indicating the danger may be a simple sound such as “dangerous” or an alarm sound.

  Here, since the bone conduction speaker is suspended from the upper floor, it is possible to sufficiently recognize the alert information without leaving immediately after contact. Moreover, since it is a bone conduction speaker, information can be transmitted only to the contact person, so that it can be easily recognized that it is dangerous. In addition, since it cannot be heard by other passengers, it does not cause anxiety to passengers other than the contactor or misunderstand that they are dangerous.

  Further, since information is not transmitted unless contact is made, there is no need for a mechanism for providing information only when the bone conduction speaker 4 is provided with a switch. There is no discomfort like broadcasting.

  It is obvious that the bone conduction speaker has the same effect even when incorporated in the triangular protective plate 3.

 It is also clear that the bone conduction speaker is effective in any shape.

1 shows an embodiment of a safety device for an escalator according to the present invention.
