Description

  The present invention relates to a sliding door.

  2. Description of the Related Art Conventionally, there is known a sliding door that allows a shoji to travel in a horizontal direction along a groove formed in a lower frame of a frame provided in an opening. The groove formed in the lower frame of the sliding door opens upward in a state where the shoji is open. When the shoji is opened, if the groove formed in the lower frame is open, it may interfere with the passage of the person who uses the wheelchair.

  In order to solve such a problem, a technique for closing a groove formed in the lower frame when the shoji is opened is known (for example, see Patent Document 1). Specifically, in this technique, by extending a closing body that rotates in accordance with the opening and closing of the shoji in the extending direction of the groove, the closing body is formed on the lower frame when the shoji is open. I try to close the groove.

JP-A-6-24188

  However, in the technique disclosed in Patent Document 1, the door is closed while the shoji is moved from the closed state to the opened state, or conversely, the shoji is moved from the opened state to the closed state. The body rises above the lower frame. If the closed body rises while the shoji is moving, it will hinder the passage of pedestrians and the like.

  The present invention has been made in view of the above problems, and since the opening of the groove formed in the lower frame is blocked in the state in which the shoji is opened, the shoji can be moved in and out smoothly. The purpose is to provide a sliding door that does not hinder the passage of pedestrians.

  The present invention includes an upper frame (for example, upper frames 21, 21A described later), a lower frame (for example, lower frames 22, 22A, 22B, 22C, 22D described later), and left and right vertical frames (for example, vertical frames described later).

Sliding doors 1, 1A, 1B, 1C, 1D), and the lower frame has a groove (for example, a groove 227, 227A, 227B, 227C, 227D, which will be described later) that opens upward and allows the shoji to run. A lower frame main body (for example, lower frame main bodies 221, 221A, 221B, 221C, and 221D, which will be described later) and a lower frame main body are disposed in the lower frame main body, and advance and retract with respect to the opening of the groove as the shoji runs. The shoji is configured Member closing the groove to close the opening of the groove in an open state (e.g., below the groove closing member 222,222A, 222B, 222C, 222D) and, to a sliding door comprising a.

According to the present invention, in the sliding door, the lower frame is disposed in the lower frame main body in which the lower frame is opened upward and the groove for allowing the shoji to travel is formed, and the opening of the groove with respect to the shoji is running. And a groove closing member that closes the opening of the groove when the shoji is open.
Thereby, in the state which the shoji was open | released, since the groove | channel formed in the lower frame main body is block | closed by the groove closing member, it can go in and out smoothly. Furthermore, since the groove closing member is disposed in the lower frame main body, the groove closing member does not protrude above the upper surface of the lower frame main body even while the shoji is moving, thereby preventing the passage of pedestrians and the like. I can't.

  The lower frame includes a biasing member (for example, biasing members 6, 6B, which will be described later) that biases the groove closing member toward the bottom surface of the shoji when the shoji is closed. 6C, 6D).

  In addition, the groove closing member preferably includes an airtight material (for example, mohair members 228, 228B, 228C and an airtight material 228A, which will be described later) at the tip in the traveling direction.

  A vertical member (for example, vertical members 33 and 33D described later) that abuts on the door end side of the shoji in a state where the shoji is closed is formed at the lower end of the groove closing member toward the end of the groove closing member. It is preferable to include a protruding portion that protrudes to the vicinity (for example, protruding portions 332 and 332D described later).

  According to the present invention, since the opening of the groove formed in the lower frame is closed when the shoji is opened, it is possible to smoothly enter and exit, and even when the shoji is moving, the passage of pedestrians and the like is hindered. It can provide a sliding door that is never used.
