Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door and a structure for installing the door which are openably and closably installed at the entrance and exit of a so-called water place such as a bathroom or a shower room.

[0002]

2. Description of the Related Art Conventionally, as this type of door, for example, one disclosed in Japanese Patent Application Laid-Open No. 11-166322 is known. The bathroom door described in FIG. 6 of the publication is a barrier-free design, and the upper surface of the lower frame thereof is flat so that the bathroom floor and the changing room floor, which are substantially flush with each other, are continuous. It is formed horizontally. Further, the waterproof property is maintained by the two sealing members provided between the lower frame and the lower end of the door body and the drain gutter provided under the bathroom floor.
In this case, the door body, by engaging the upper and lower movable side pieces of the pin hinges incorporated in the vertical frame with the upper and lower fixed side pieces of the pin hinges fixed to the upper frame and the lower frame, respectively, in a rotatable manner, It is mounted on the door frame so that it can be opened and closed.

[0003]

By the way, in a barrier-free designed bathroom, the conventional water stop structure provided with a drain gutter requires complicated cleaning of the drain gutter, and if possible seals only the sealing member. The structure is preferable. In this case, it is necessary to provide a drainage gradient on the lower frame in order to drain the drainage partially leaked from the seal member to the bathroom side. On the other hand, if the lower frame is provided with an inclination (drainage gradient), the fixed side piece fixed to the lower frame also needs to be provided with an inclination on its seating surface, and the directional mounting of the fixed side piece becomes complicated, There is a problem that versatility is impaired, such as the inability to cope with changes in the tilt angle.

The present invention relates to a lower frame having a drainage gradient,
It is an object of the present invention to provide a door and a door installation structure in which a fixed side piece of a pin hinge can be easily attached with good workability.

[0005]

In the door of the present invention, the door body is attached to the door frame so as to be openable and closable by a pin hinge composed of a fixed side piece provided on the door frame and a movable side piece provided on the door body. In the door, the lower frame of the door frame is
At least the portion where the lower end surface of the door body in the closed state faces is formed to be inclined in the prospective direction, the fixed side piece is fixed to the concave portion formed on the upper surface of the lower frame, and the bottom surface of the concave portion is horizontally formed and fixed. The side piece is fixed while being seated on the bottom surface of the recess.

According to this structure, for example, a concave portion for the fixed piece is formed in the lower frame having an inclined drainage gradient, and the bottom surface of this concave portion is formed horizontally. Thus, the fixed side piece can be seated horizontally in the concave portion and fixed, so that the lower surface of the fixed side piece need not be inclined, and this can be a simple and versatile structure. Further, it is not necessary to consider the strict directionality when attaching the fixed side piece, and this can be easily attached. Furthermore, it can be suitably applied to the entrance door of a water plant with a barrier-free design.

In this case, the concave portion extends in the finding direction,
A spacer is preferably mounted in the recess so as to be flush with the upper surface of the lower frame, except for the mounting portion of the fixed side piece.

According to this structure, the spacer is seated horizontally along with the fixed side piece in the concave portion extending in the finding direction, and the spacer can appropriately secure the drainage gradient of the lower frame. Further, since the upper surface of the lower frame and the upper surface of the spacer are flush with each other, the foot landing property is not impaired, and it is possible to effectively prevent drainage, dust, etc. from accumulating in the recess. In addition, it is preferable that the spacer is formed of a shape material such as aluminum or a resin molded product.

The door installation structure of the present invention is the above-described door installation structure including the door of the present invention, wherein the upper surface of one end of the lower frame in the prospective direction is substantially flush with the floor of the bathroom floor. The upper surface of the other end is substantially flush with the floor surface of the dressing room floor.

According to this structure, the floor of the bathroom and the floor of the dressing room are connected with a gentle slope by the upper surface of the lower frame.
As a result, the water can be properly drained to the floor side of the bathroom, and the foot landing property is not impaired. Therefore, although the bathroom floor and the changing room floor are not flat, a barrier-free structure that does not cause a step to be felt, that is, has no discomfort can be provided.
