Description

  The present invention relates to a handrail device for an entrance / exit provided in an entrance / exit of an elevator provided on a building side.

  In recent years, in response to the arrival of an aged society, when a senior citizen uses an elevator, a technology related to a handrail device for securing a safe getting on and off operation by assisting the getting on and off of the elevator has been proposed (for example, a patent) Reference 1 and Patent Reference 2).

  The handrail device shown in Patent Document 1 is intended for a structure in which an elevator entrance / exit provided on the building side is provided at a deep position from the side wall surface of the building, and is provided for the convenience of those who get on and off with a wheelchair. For this purpose, the handrail attached to the side wall surface of the building is extended to the vicinity of the front end of the entrance through the side wall of the entrance and exit, so that a person on the wheelchair can pass the handrail from the building side to the vicinity of the front end of the entrance and exit. It is designed to move around.

  In this case, in this handrail device, the side wall portion of the entrance / exit is a flat surface extending vertically from the entrance / exit or a curved surface expanding and changing outward, and a concave groove extending horizontally is formed on the side wall portion. And a handrail is disposed in the groove.

  The handrail device shown in Patent Document 2 is a device in which an entrance corner portion extending in the vertical direction is formed at an outer end portion of a doorway formed in the building wall surface, and a handrail is attached in the entrance corner portion. , The presence of the user is detected by the user holding the handrail by hand, and the opening time of the elevator door is set to be long, which makes it particularly safe when getting on and off when the user is an elderly person.

  By the way, the left and right side walls of the elevator entrance / exit provided on the building side are directed from the back side of the entrance / exit to the near side from the viewpoint of facilitating the movement of people accompanying entry and exit of the entrance / exit. Along with this, the inclined surface or the curved surface tends to be enlarged.

  On the other hand, when an elevator user is an anxious person such as an elderly person, the user usually wants to get on and off the elevator safely through a handrail. In this case, handrails are generally provided on the wall surface of the passage leading to the elevator in the building, and handrails are also provided in the gondola of the elevator. In addition to the case where a wheelchair user is targeted as shown in Document 1, a handrail is usually not provided (the example shown in Patent Document 2 is mainly intended to sense the presence of a person. Handrail, not for walking assistance).

  This is probably because the length in the moving direction at the side wall portion of the entrance / exit is short, and it is judged that there is a handrail on the side of the building wall and a handrail in the gondola of the elevator.

  However, the handrail inside the gondola is provided on the side of the gondola so that it cannot be gripped at the same time as it enters the entrance. For this reason, even if the distance between the side walls of the entrance / exit is short, it is difficult to move immediately from the handrail on the building wall side to the handrail inside the gondola (and vice versa), especially for elderly people This is a serious problem.

  Here, in order to deal with such a problem, it is conceivable to apply the handrail shown in Patent Document 1 or Patent Document 2.

  However, as described above, the handrail device shown in Patent Document 1 has a structure in which the front end of the entrance / exit is set at a position where the front end of the entrance / exit is deeply inserted from the passage. Since the side wall portion of the entrance / exit is provided with a concave groove in the horizontal direction, and a handrail extending continuously from the passage side is extended here, the width of the side wall of the entrance / exit is relatively small. It is difficult to apply to elevators having a structure, and even if it is applied temporarily, the structure is large and the effect corresponding to the installation cost is difficult to obtain.

  The handrail device disclosed in Patent Document 2 is for sensing the presence of a person by grasping the handrail, and the person who is going to get on the elevator holds the handrail in a state where the person stops at the entrance / exit. For this reason, handrails are arranged at the corners between the side wall of the entrance / exit and the passage wall surface, that is, the portion that is most easily gripped while standing in front of the entrance / exit. Therefore, although this handrail is close to the handrail on the wall surface of the building, it is far from the handrail in the elevator gondola. Therefore, this handrail is used to bridge the handrail from the handrail on the building wall side to the handrail in the elevator gondola. However, it is not possible to expect a sufficient effect, and in particular, the left and right side walls of the entrance / exit are inclined surfaces or curved surfaces that expand the opening width of the entrance / exit from the back side toward the front side. This is even more so.
