Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upper frame device for a window frame which is fitted and fixed in an opening provided in a building.

[0002]

2. Description of the Related Art Needless to mention specific examples, a frame piece projecting in the outer peripheral direction is provided on an upper frame of a window frame, and this frame piece is directly superimposed on an outer wall of a building to stop nails, screw rods and the like. There is a structure fixed by a rod.

[0003]

The prior art employs a structure in which a frame piece is directly superimposed on an outer wall and fixed with a fastening rod to fix an upper frame to a building. Rainwater infiltrates into the interior, and the infiltrated rainwater may eventually flow into the indoor side, and in order to prevent this, it is common to expect the decorative wall arranged outside the outer wall to be watertight, In order to enhance the watertightness, the construction of the decorative wall is complicated.

[0004] In view of the above situation, the present invention has been developed with the object of providing an upper frame device which can be expected to be watertight due to a simple structure irrespective of a decorative wall and does not have the possibility of rainwater flowing into the indoor side. It was done.

[0005]

A pair of indoor and outdoor frame parts projecting in the outer peripheral direction are provided on the outdoor side of an upper frame of a window frame fitted and fixed in an opening provided in a building, and the outdoor side frame part is provided. The first watertight elastic material is fixed to the mounting groove of the indoor opening provided in the piece, and the outdoor frame piece is fixed to the outer wall of the building via the first watertight elastic material, and The upper end portion of the indoor side frame portion piece is pressed against the outdoor side of the upper wall portion of the opening via the second watertight elastic material, and directly below the contact portion between the outer wall and the first watertight elastic material. The bottom wall of the formed empty room is provided with a communication hole which is located on the outdoor side with respect to the sliding door engaging portion provided on the upper frame and communicates the empty room with the outdoor.

[0006]

The first watertight elastic member is elastically deformed by being interposed between the outdoor side frame piece and the outer wall of the building without coming off from the mounting groove of the outdoor side frame piece and pressed against them to press the outdoor side frame portion. Ensure water tightness between the piece and the outer wall.

Further, even if rainwater enters between the outdoor side piece and the outer wall, it is collected in the vacant room, and the indoor side frame piece and the second watertight elastic material prevent the rainwater from entering the indoor side. Then, the water is drained outside through a communication hole provided in a bottom wall of the empty room.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a sectional view showing an embodiment of an upper frame device of a window frame according to the present invention. FIG. 1 is a sectional view showing a first embodiment, and FIG.

In each of the figures, reference numeral 1 denotes an upper frame of a window frame A fitted and fixed in an opening h provided in a building B, and an upper frame 1 is a pair of indoor and outdoor frame portions provided so as to protrude in the outer peripheral direction thereof. 2 and 3, while fixing the outdoor side frame piece 2 to the outer wall W of the building B via the first watertight elastic member 4 by the fastening rod 5;
The indoor side frame piece 3 is fixed to the building B so as to be pressed against the upper wall 7 of the opening h via the second elastic member 6 for watertightness.

Reference numeral 8 denotes a vacant space which is arranged horizontally with the indoor and outdoor frame pieces 2 and 3 and which includes an outdoor side portion of the main body piece 9 of the upper frame 1 and a part of the building B. A communication hole 11 is provided in the bottom wall 10 of the empty room 8 (constituted by the outdoor portion of the main body piece 9), and the communication hole 11 is provided on the lower surface side of the main body piece 9. It is located on the outdoor side of the sliding door engaging portion 12 and constantly communicates the outdoor with the empty room 8.

The first elastic member 4 for watertightness includes a pair of upper and lower horizontal pieces 13 projecting from the indoor side surface of the outdoor frame piece 2.
13 'is attached to the upper frame 1 by fitting the base into the mounting groove 14 of the indoor surface side opening formed by 13', and the free end is the outer wall W
, So that rainwater on the contact portion (boundary portion) 15 between the outer wall W and the outdoor side frame piece 2 is prevented as much as possible.

The vacant space 8 is located immediately below the contact portion 15 between the outer wall W and the first watertight elastic member 4.

[0013]

FIG. 1 shows a first embodiment in which the present invention is applied to an upper frame of a window frame for a sliding sliding door. The supporting portion 3a corresponding to the corner formed by the building outer wall W and the upper wall 7 is provided on the upper portion, and the second watertight elastic member 6 is mounted on the upper surface side of the supporting portion 3a. The elastic material 6 is pressed against the upper wall 7 as well as the outer wall W to prevent rainwater from flowing into the indoor side along the upper wall 7.

Incidentally, the sash engaging portion 12 is constituted by an upper guide rail of the outer sash.

[0015]

Second Embodiment A second embodiment shown in FIG.
In the second embodiment, the present invention is applied to an upper frame of a window frame for raising and lowering shoji, wherein 2 is constituted by an engaging portion of a shoji.
While the indoor frame piece 3 of the first embodiment is arranged vertically in parallel with the outdoor frame piece 2, the frame piece 3 is gradually inclined upward in the indoor direction, and is arranged in the building. The upper end of the second watertight elastic member 6 engaged with the recess 16 provided in the upper wall 7 is pressed into contact with the second watertight elastic member 6. 11 to improve the efficiency of drainage to the outdoors.

FIG. 17 shows a cover frame for hiding the head of the fastening rod 15, which is fitted to the upper frame 1 by utilizing its elasticity.

[0017]

According to the present invention, since the frame piece of the upper frame is fixed to the outer wall of the building via the watertight elastic material, infiltration of rainwater from the frame piece and the outer wall is prevented as much as possible. be able to.

Further, even if rainwater enters, it flows into the empty room and is drained outside through the communication hole, so that the rainwater does not flow into the indoor side.

Furthermore, even under a strong wind, even if a rain wind blows into the space between the upper frame and the building, the vacant room becomes equal in pressure to the outside, and this can be prevented.
