Description

  The present invention relates to a folding door unit for replacing a cantilever toilet door with a folding door.

  Many toilet doors are cantilever doors in which one side of the door plate is pivotally supported on the side of the opening via a hinge. This type of hinged door opens the door by pulling the handle on the right or left side of the door plate.

  Such a hinged door has a problem that it is difficult to open the door when entering and exiting because there is no sufficient space around the doorway of the toilet because the door plate opens with the hinge on one side as the rotation center.

  In welfare facilities and elderly facilities, it is necessary to provide handrails in the corridor. However, in the case of cantilever hinged doors or sliding doors, the location of handrails around the entrance of the toilet may be limited.

  Therefore, recently, there is an increasing demand for construction for replacing (replacement) the hinged door with a folding door. The folding door has an advantage that the attachment of the handrail is not limited.

  When replacing a conventional door with a folding door, conventionally, as shown in FIG. 10, after removing the toilet door plate 1 from the opening 3 and removing the hinge 2 supporting the door plate 1, FIG. The folding door 5 was fixed to the opening 3 via a new hinge 4 as shown in FIG. 6 is a wooden frame provided for pivotally supporting the cantilever door plate 1. The hinges 2 and 4 are attached using this wooden frame 6. Further, in order to guide the linear movement of the folding door 5, a guide groove member (not shown) is provided at the upper edge of the wooden frame 6, and the runner member (member) provided at the upper end of the folding door 5 is The guide groove member is loosely fitted.

  Conventionally, as a technique of a folding door for a toilet, there is one shown in Patent Document 1. This is to allow a wheelchair to enter the toilet opening when the folding door is opened.

  The problem is that the construction cost for replacing a single door with a folding door increases.

  This is because, when the folding door 5 is attached to the wooden frame 6 remaining after the one-sided door plate 1 is removed, a plurality of sturdy hinges 4 are attached to withstand the weight of the folding door 5, and the weight of the folding door 5 is increased. This is because it is necessary to use a strong guide groove member attached to the upper edge of the wooden frame 6 in order to withstand.

  Accordingly, an object of the present invention is to improve the workability of the remodeling work for exchanging the toilet door with the folding door and to reduce the construction cost.

  To achieve the above object, a toilet folding door unit according to the present invention replaces a toilet door with one side of a door plate pivotally supported on the side of an open wooden frame via a hinge. As a technical premise that it is a folding door unit, it consists of a frame member made of aluminum that has a rectangular shape, and a folding door body that is attached to this frame member, and this folding door body has wheels at the lower end, The upper end portion is provided with a guide concave portion or convex portion, and the frame member has a plurality of screw holes in the upper frame, the lower frame, and the left and right side frames, and a guide rail portion for guiding the wheel on the lower frame. And the upper frame is provided with either one of a convex portion or a concave portion that is loosely fitted to a guide concave portion or a convex portion provided in the folding door body (Claim 1).

  According to such a configuration, the folding door main body attached to the frame material can be installed to be opened and closed simply by fixing the frame material to the wooden frame of the opening of the toilet door. The movement of the heavy folding door body can be supported by the wheels. Shaking (rattle) of the folding door body at the time of opening and closing is loosely fitted in the concave portion or convex portion provided in the upper end portion of the folding door main body, and the convex portion or concave portion provided in the upper frame of the frame material (free fitting of the folding door). It can prevent by making it the fitting state which does not prevent opening and closing).

  The second aspect of the present invention more reliably prevents shaking of the folding door body during opening and closing. The wheel provided at the lower end of the folding door body is attached via a pedestal having an inverted U-shaped groove, and the guide rail provided on the lower frame of the frame material stands from an appropriate position on the horizontal plate material fixed to the floor surface. The raised vertical plate member and a flange portion provided in the horizontal direction from the upper end of the vertical plate member are provided, and the flange portion is loosely fitted in the groove portion of the seat.

  According to such a configuration, since the seat supporting the wheels is guided by the flange portion of the guide rail portion of the frame material lower frame, it is possible to reliably prevent the lower end portion of the folding door body from shaking (rattle) during opening and closing. it can.

  According to the toilet folding door unit according to the present invention, simply by fixing the unit frame material to the wooden frame of the toilet door opening, the folding door body attached to the frame material can be installed easily and opened. I can do it. The folding door unit can be manufactured in the factory in advance, and the work can be shortened because the work is completed simply by attaching a frame material at the time of reform. For this reason, it is possible to reduce the construction cost when renovating a toilet door and replace it with a folding door, thereby enhancing the competitiveness.
