BACKGROUND OF THE INVENTION
The present invention relates to a handrail device that can be suitably implemented at an entrance of a building in which a sliding door such as a sliding door is provided.
[0002]
[Prior art]
In recent years, as a countermeasure for the elderly, in apartment buildings, at the entrances and exits of the veranda and the room, handrails are used to replenish the balance of the body during passage in order to encourage elderly people to pass easily and safely. A device is provided. This handrail device has a bar-shaped handrail member and a bracket that holds the handrail member with a space in front of the prospective direction with respect to the indoor side wall surface and the outdoor side wall surface.
[0003]
Such handrail devices are provided on both sides of the indoor side wall surface in the frontage direction, and are provided on both sides of the outdoor side wall surface in the frontage direction. When the sliding door is a sliding door, the sliding door is configured by a joinery frame that is fixed to the inner peripheral portion of the opening with an entrance formed in the wall of the building, and, for example, two shojis that are held by the joinery frame. . The joinery frame includes a pair of eaves frames, an upper frame that connects the upper end portions of the eaves frames to each other, and a lower frame that connects the other end portions of the eaves frames to each other. Each of the frame, the upper frame, and the lower frame is made of an extruded material of an aluminum alloy, and is realized as a so-called sash frame.
[0004]
Each shoji is basically provided with a pair of scissors, an upper scissors that connect the top ends of each scissors to each other, a lower scissors that connect the other ends of each scissors, and the lower reeds. Is connected to the middle part between the upper end and the lower end of each cage, and is supported by the middle beam provided in parallel with the upper and lower cages, and each cage, the upper cage and the middle beam. It includes an upper glass and a lower glass held by each fence, middle rail, and lower fence.
[0005]
These shojis are supported so as to be movable in the frontage direction with the door wheel supported by a rail formed integrally with the lower frame, and the right or the right when traveling from indoor to outdoor and from indoor to outdoor. Either one of the shojis arranged on the left is selectively moved to form an opening, and after passing through the opening, the moved shoji is moved until it comes into contact with one of the heel frames to close the opening. To do.
[0006]
When the passerby is an elderly person or a physically handicapped person, the handrail member of the handrail device provided in the vicinity of one of the shojis that opens or closes the shoji to stabilize the body during passage as described above It is provided on both the left and right side walls in the direction of travel until it is gripped, and is provided on both the indoor side wall surface and the outdoor side wall surface. However, even if the right or left shoji is further operated in the direction of travel, any one handrail member of handrail devices provided at a total of four locations inside and outside is grasped to stabilize the body. The sliding doors can be opened and closed in a state where they are in a smooth state, allowing them to pass smoothly.
[0007]
[Problems to be solved by the invention]
In such a conventional technique, each handrail device described above is provided on each of the left and right sides of the indoor side wall surface and the outdoor side wall surface. Therefore, when a passer opens the shoji and passes through the opening, the handrail device moves from the room to the outside. Sometimes, among the handrail members provided on the indoor side wall surface, one of the handrail members on the side where one of the handbags to be opened is held is opened, and the one of the handbags is opened and moved to the outdoor side. . At this time, the arm on the side holding the one handrail member is restrained as the passerby's body moves from the room to the room outside, so that the posture during passage is toward the room side, that is, an oblique direction. You have to move outside in an unnatural posture. In addition, in the state where the body of the passer-by is placed outside the joinery frame and on the outdoor side, it becomes difficult for the passer-by to hold the one handrail member on the indoor side, It is necessary to bring it back to the handrail member. Such picking up of one handrail member provided on the indoor side wall surface and one handrail member provided on the outdoor side wall surface not only causes anxiety for the elderly and the physically handicapped, but also makes the body unstable. Therefore, there is a problem that the risk of falling and wobbling increases.
[0008]
Furthermore, by providing handrail devices on both the left and right sides of the indoor side wall surface and the outdoor side wall surface, it is possible to fully open the opening that occurs when the shoji is opened. Even if you try to grip handrail members that are arranged close to you in order to stabilize the posture, etc., each handrail member is not provided facing the passerby, so you can quickly find and grip the handrail member However, there is a problem in that sufficient assistance cannot be obtained during passage for elderly people and persons with physical disabilities who are more likely to interfere with smooth passage as compared with healthy people.
[0009]

【The invention's effect】
According to the first aspect of the present invention, when the handrail member is not used, only the mounting member is fixed to the frame, and the handrail member and the bracket protruding in the opening generated when the shoji is opened are removed. Since it can be stored in a predetermined storage location and attached to the attachment member when necessary, the convenience of using the handrail device can be improved. In addition, since the handrail member is provided substantially parallel to the mounting member, the handrail member does not protrude greatly into the opening formed when the shoji is opened, and the passage is not hindered. In addition, since the handrail member is connected to the mounting member with an interval in the frontage direction, it is optimally set to such an extent that the handrail member can be easily and reliably grasped when the passerby passes through this interval. By doing so, the handrail member can be firmly grasped and the body can be stabilized. In addition, since the handrail member is connected to the mounting member by the connecting means substantially in parallel with the mounting member, it is always mounted without greatly changing the posture during the movement from the indoor to the outdoor and the movement from the outdoor to the indoor. The state in which the member is gripped can be maintained, and the body is greatly rearward in the passage direction while holding the one handrail member regardless of whether the passage is from the indoor to the outdoor or the outdoor to the indoor. It is possible to pass in a stable state without inclining, avoiding the unstable state of the body due to re-handling of the handrail member, and smoothing for passers-by, especially the elderly and disabled persons Can be supported.
[0049]
According to the second aspect of the present invention, since the handrail member is connected by the connecting means so as to be displaceable between the retracted position and the protruding position, the handrail member is disposed at the protruding position when passing, and the handrail member and the mounting member are arranged. A sufficient space can be secured between the handrail and the hand or the arm so that the handrail member can be inserted easily. In addition, when it is not possible to pass through or when it is not possible to secure a sufficient opening width with respect to the movement of the article, the handrail member is retracted to the retracted position to easily secure an opening with a sufficient opening width for the passage of the article. Can do. In this way, the handrail member can be selectively displaced between the retracted position and the protruding position by the connecting means, and convenience in use is improved.
