Description

This disclosure relates to a guide support member and a sliding door. Conventionally, guide devices are known that suppress the swaying of a door when it is opened or closed while suspended by a sliding door rail or the like. For example, the guide device described in Patent Document 1 consists of a guide projection provided on the floor surface beneath the track on which the door body travels, which can extend and retract from the floor surface; a running groove provided on the lower end surface of the door body into which the guide projection is inserted; and a magnetic attachment means having a magnet. When the door body is opened or closed, if the magnet reaches the guide projection, the guide projection is attracted to the magnet and protrudes from the floor surface. In this protruding state, the guide projection engages with the running groove. When the door body is opened or closed in this state, the guide projection moves along the running groove. This makes it possible to suppress the swaying of the door body during opening and closing.

(First Embodiment) The guide support member 30 of this embodiment will now be described with reference to Figures 1 to 9. The guide support member 30 is applied to a sliding door 1. The sliding door 1 is a top-hung sliding door. The sliding door 1 is installed, for example, in an opening O provided in a partition wall of a building. As shown in Figure 1, the sliding door 1 comprises, for example, a door body 20 having a shoji screen 21. The door body 20 is suspended from, for example, an upper rail (not shown) provided along the upper edge of the opening O, and is opened and closed along the direction in which the upper rail extends. In this specification, "visible direction" refers to the direction in which the interior-facing surface of the sliding screen 21 attached to the sliding door 1 extends. "Left-right direction" refers to the horizontal direction in the visible direction, and is the left-right direction when the sliding door 1 is viewed from the interior. "Opening/closing direction" refers to the opening and closing direction of the sliding screen 21. The opening/closing direction is the left-right direction. "Depth direction" refers to the interior-exterior direction of the sliding door 1. The depth direction, the opening/closing direction (left-right direction), and the up-down direction are mutually orthogonal. Furthermore, multiple guide pins 10 are provided on the floor surface G. Each guide pin 10 is positioned to overlap vertically with the trajectory of the shoji screen 21 during opening and closing. For example, there are two guide pins 10 per shoji screen 21. Each guide pin 10 is spaced apart horizontally. The distance between adjacent guide pins 10 is, for example, approximately 400 mm. Each guide pin 10 can extend and retract from the floor surface G. The portion of each guide pin 10 that can extend and retract from the floor surface G is made of a magnetic material such as iron. Therefore, each guide pin 10 is pulled out from the floor surface G by magnetic force. The configuration of the guide pins 10 will be described in more detail later. The door frame 20 comprises a sliding screen 21, a guide rail 25, and a pair of left and rig
