Description

[Detailed explanation of the idea] The present invention relates to a removable window rail for buildings.

Generally, window handrails in high-rise houses, snowy areas, etc. are often provided on the indoor side of windows to prevent falls and to prevent snow from accumulating on the windows.

However, most conventional window handrails are fixed to the window frame, which has the disadvantage that in the event of an emergency such as a fire, the handrail gets in the way and makes it difficult for firefighters and others to enter the room. Ta.

In addition, a proposal has been made in which a guide rail is provided in the vertical direction of the window frame, the handrail is slidably supported on the guide rail, and the handrail can be removed from the window frame by pulling the handrail upward in an emergency. In this case, in order to remove the handrail from the guide rail, it is necessary to pull it upward by almost the same height as the handrail, which not only takes time, but also makes it difficult to remove the handrail from the guide rail when the height of the handrail is more than half the height of the window frame. This had the disadvantage that the handrail would hit the window frame, making it impossible to remove it.

Therefore, the present invention has a window frame with guide rails fixed to both sides, and a guide is provided in the vertical direction on the guide rail,
A handrail main body is engaged and supported by the guide so as to be slidable in the vertical direction via one or more engaging means provided on each side of the main body, and a notch is provided in the guide to allow the handrail main body to By moving the handrail body upward, at least the retaining means provided at the lowest position of the engaging means is aligned with the notch, and by further pushing the handrail body toward the indoor side, the handrail body is attached to the guide rail.
