Description

  The present invention relates to a joinery, and in particular, an opening frame in which a rail portion is detachably arranged with respect to a lower frame, a sliding arrangement on the opening frame via the rail portion, and the opening frame is closed. In this case, the present invention relates to a joinery including a plurality of shojis arranged in a state in which the vertical shafts face each other.

  In recent joinery, in order to realize barrier-free, an upper end portion of a rail portion that supports a shoji is configured in a flat plate shape and the entire height is made uniform. Since this type of joinery can eliminate the step in the lower frame, it is highly safe and easy to use for the elderly and the disabled. However, a joinery in which the upper end portion of the rail portion is configured in a flat shape is not necessarily preferable in consideration of maintenance properties such as a complicated operation of removing foreign matters such as dust that has entered the interior.

  For this reason, conventionally, there is also provided a configuration in which the rail portion is configured to be detachable from the lower frame, and the rail portion is removed from the lower frame when performing maintenance. The rail member which is a long member is, for example, equally divided, and its handleability is also considered. According to such a joinery, barrier-free can be realized without impairing maintenance (see, for example, Patent Document 1).

  By the way, in a joinery where two shojis are in a state where they face each other when the opening frame is closed, such as a four-story building, each shoji is directed indoors when it receives wind pressure from the outdoor side. It may be curved to be convex. In the joinery described in Patent Document 1 described above, each of the shojis has a curved shape, although a block-like member having fin portions overlapping each other in a prospective direction is provided between the vertical fences to be faced to improve airtightness. When it is deformed, the distance between the vertical gutters increases, and it is difficult to completely block the outside air from entering the room.

  Here, in the joinery in which the rail portion is configured to be detachable with respect to the lower frame, water such as rainwater dripped from the shoji to the lower frame is inserted in the longitudinal direction and the lateral direction through the gap between the lower frame and the rail portion. It is movable. In particular, in a joinery in which the rail part is divided, water may appear in the upper part of the lower frame through the dividing surface of the rail part. For this reason, when the water of a lower frame reaches | attains between vertical fences, there exists a possibility of entering into a room inner side comparatively easily with the advancing air.

  In view of the above circumstances, an object of the present invention is to provide a fitting that can prevent as much as possible a situation in which water enters the room from between the faced vertical fences.

In the fitting, the rail portion extends in the longitudinal direction from the butting position of the shoji when the opening frame is closed. the shift position is in the longitudinal direction of the lower frame in a state where the divided surfaces arranging a plurality of one of a portion including a butt position of the shoji in the longitudinal direction between said rail portion and the lower frame The water-stopping material is provided only at the portion, and the drainage holes are provided at positions corresponding to both ends of the water-stopping material in the lower frame .

  According to the present invention, since the dividing surface of the rail portion and the butting position of the shoji are shifted from each other in the longitudinal direction, the water that has reached the dividing surface of the rail portion immediately passes through the space between the butting positions. There is no fear of being carried inward, and it is possible to suppress a situation in which water such as outside air or rainwater blown from the abutting position enters the dividing surface of the rail portion. And the movement of water to the butting position of the shoji is suppressed by the water stop material.

  According to this invention, the water whose movement is suppressed by the water stop material is discharged from the lower frame through the discharge hole and is not stored in the lower frame.

  Further, in the joinery described above, according to the present invention, the shoji placed in a state where the downspouts face each other is provided with a block member having a polymerization fin portion overlapping each other in a prospective direction at each lower end portion. Features.

  According to this invention, since the labyrinth is formed in the butt portion of the shoji by the fin portion of the block member, the passage of outside air and water is suppressed.

  Further, in the joinery described above, according to the present invention, the rail portion has a flat shoji support surface that supports the shoji on the upper portion and is disposed flat with respect to the upper surface of the lower frame. Features.

  According to this invention, there is no step on the upper surface of the lower frame, and a fitting suitable for barrier free can be provided.

  Moreover, the present invention is characterized in that, in the above-described joinery, the water-stopping material is attached to the finding surface of the rail portion.

  According to the present invention, the water stop material is not affected by the mounting height of the rail portion, and the water stop material is attached to the finding surface where the water is difficult to move upward from below. can do.

  According to the present invention, since the dividing surface of the rail portion and the butting position of the shoji are shifted from each other in the longitudinal direction, the water that has reached the dividing surface of the rail portion is immediately chambered by the air that passes between the vertical shafts. There is no fear of being carried inside. And since the movement of the water to the butt | matching position of a shoji is suppressed by the water stop material, the situation where water infiltrates into the room | chamber interior from between the butt | matched vertical fences can be prevented as much as possible.

As shown in FIG. 4, the water that has moved to the positions that become both ends of the water blocking material 30 is also discharged to the outside of the lower frame 12 through the drain holes 12f. Therefore, even when the outside air enters the indoor side from between the butting rods 23 due to the wind pressure from the outside of the room, the inner impingement 20 is curved, There is no danger of water entering the room.

  In the above-described embodiment, a four-story sliding window in which the four shojis 20 are arranged in the left-right direction with respect to the opening frame 10 is illustrated, but when the opening frame is closed, they are vertically As long as the joinery is provided with a plurality of shojis arranged in a state where the heels are in contact with each other, it can be applied to other joinery such as a 3-story sliding window and a 6-story sliding window.

  Moreover, in embodiment mentioned above, since the water stop blocks 140 and 150 are mounted | worn with the lower end part of the butt | matching gutter 23, although water permeation can be suppressed more reliably, the water stop blocks 140 and 150 can be suppressed. Need not be worn.

  Further, in the above-described embodiment, as shown in FIG. 4, since the water stop material 30 is attached to the finding surface of the rail portion 14, the water stop material 30 affects the mounting height of the rail portion 14. In addition, since the water-stopping material 30 is disposed in a posture along the vertical direction, it is possible to effectively prevent water from entering. However, it is also possible to form a joinery by attaching the water stop material 30 to the lower frame 12.

  Furthermore, in embodiment mentioned above, although the joinery in which the rail part 14 became the structure divided into 2 is illustrated, it is good also as a structure where a rail part is divided into 3 or more. For example, in the case of a joinery where the rail part has a three-part configuration and the shoji butting position is the center rail part, the only water stop is included in the part including the butting position between the center rail part and the lower frame. A material may be disposed. In addition, when providing a drain hole, it is preferable to arrange | position to the site | part corresponding to both the edge parts of a water stop material, respectively.
