Description

[Detailed Description of the Invention] The present invention relates to a drainer that improves the rain protection of the sash lower frame by providing a draining member on the outdoor side of the sash lower frame.

Conventional guttering attached to aluminum sashes is connected to the sash by inserting the upper end of the guttering member between the sash sill and the window sill, or by overlapping it with the sash sill from the outside, and this connection is fastened to the window sill from the outside. In this way, conventionally, the connection between the guttering member and the sash sill is fastened with screws, which means that rainwater can seep into the interior through the screw fastening part, making it difficult to provide proper rainproofing. On the other hand, if the connection is not fastened with screws, the connection will become loose,
This caused a new drawback in that rainwater could seep inside the building through the loosened parts.

The present invention has been made in view of the above points, and instead of attaching the connecting part of the draining member and the sash lower frame with screws, any shielding part with the outdoor side is fixed with screws, and the sash lower frame is fixed with screws. In contrast, the present invention proposes a drainer in which the connection part of the drainer member has a press-contact structure, thereby improving rain protection at the screw fixing part and the connection part.

Embodiments of the present invention shown in the drawings will be described in detail below. Figure 1 is a vertical sectional view of this embodiment in use;
The figure is a partially exploded sectional view of FIG. 1.

In the above-mentioned figures, the drainer of this embodiment has a drainer member 1 connected to the outdoor side of the sash lower frame 10, and a connecting part 2 to the sash lower frame 10 has an overhanging part 3 that is inclined toward the outdoors. In addition to providing the projecting portion 3
A hanging part 4 is provided in front of the overhang part 3, and an inclined mounting piece 5 whose outdoor side is substantially shielded by the hanging part 4 is provided on the lower surface of the overhang part 3, and this mounting piece 5 is attached to a window sill. 20, the connecting portion 2 is brought into pressure contact with the sash lower frame 10.

As described above, the draining member 1 used in this embodiment
is composed of a connecting part 2, an overhanging part 3, a hanging part 4, and a mounting piece 5, and the connecting part 2 is formed in a vertically U-shaped cross section with an opening on the indoor side. A tight material 2a is filled and brought into contact with the hanging wall 11 of the sash lower frame 10 from the outdoor side.
A tight material 11a is filled between the hanging wall 11 of the sash lower frame 10 and the window sill 20, and the part is fixed with screws 12. By abutting and covering the portion of the hanging wall 11 that is secured by the screws 12 with the connecting portion 2, rainwater or the like is reliably prevented from entering the portion of the hanging wall 11 that is secured with the screw.

The projecting part 3 is formed by a planar inclined plate extending downwardly from the lower end of the connecting part 2 toward the outdoors, and has a hanging part 4 hanging from the front lower part thereof. This projecting part 3 is provided to allow rainwater that has passed from the sash lower frame 10 and the connecting part 2 to drip outdoors. Any deformed structure can be adopted in conjunction with this. Further, the hanging portion 4 hangs down linearly, and its lower end is bent toward the outdoors to further improve the draining effect.

The mounting piece 5 is formed of an inclined piece that extends downwardly from approximately the center of the lower surface of the overhanging portion 3 toward the window sill 20 side, and the lower end portion 5a of the mounting piece 5 is bent to attach to the window sill 20.
It is in contact with the outer wall surface of 0. This mounting piece 5 is
Since the hanging part 4 is located on the outdoor side, the outdoor side is substantially shielded by the hanging part 4. From approximately the center of the mounting piece 5 whose outdoor side is shielded, the window sill 20
Screw the screw 6 in an upwardly sloping manner to the mounting piece 5.
is fixed to the window sill 20. By screwing the screw 6 into the window sill 20 from the inclined mounting piece 5 in this way, the horizontal component of the pressing force of the screw 6 presses the entire draining member 1 toward the window sill 20 side. , the above-mentioned connecting portion 2 is brought into pressure contact with the sash lower frame 10. This pressure contact further improves the airtightness between the connecting portion 2 and the sash lower frame 10. Since the screws 6 are shielded from the outdoors by the hanging portions 4, there is no risk of rainwater intruding, and a good appearance can be maintained. However, the lower end portion 5a is
Although it is slightly exposed from the lower surface of the hanging portion 4, there is no problem with the appearance. Since this lower end portion 5a is bent and is in surface contact with the window sill 20, the pressing force of the screw 6 allows an airtight contact state with the window sill 20 to be obtained. A plurality of through holes 6a for screws 6 are bored approximately in the central longitudinal direction of the mounting piece 5.

As shown in FIG. 1, end caps 8 made of synthetic resin are attached to both side ends of the draining member 1 to prevent rainwater from dripping from both sides. Further, although the sash lower frame 10 is constructed as a fitted window, the present invention is not limited to this, and may be constructed as a shoji window.

FIG. 3 is a longitudinal sectional view of another embodiment, and the draining member 1 in the same figure has a connecting part 2 and a mounting piece 5 different from the first embodiment, and is basically different from the first embodiment. They have the same configuration.

First, the connecting portion 2 is formed in a horizontal L-shape, and has a screen door rail 7 provided on the upper surface of the horizontal piece, and an insertion piece 2b protruding from the lower surface of the tip. On the other hand, the hanging wall 1 of the sash lower frame 10 to which this connecting portion 2 corresponds
1 is provided with a hook portion 13, into which the insertion piece 2b of the connecting portion 2 is inserted together with the tight material 2a. In particular, by making the contact surface between the insertion piece 2b and the hook portion 13 slanted, the insertion piece 2b can be wedge-shaped and press-fitted into the hook portion 13. By adopting such a configuration, the connecting portion 2 of the second embodiment can be brought into even stronger pressure contact with the sash lower frame 10. Also tight material 2a
Since it is interposed, the airtightness of the pressure-welded portion can be further improved. Furthermore, since the connection part 2 is pressed against the sash lower frame 10 by a locking structure using the hook part 13, the installation of the draining member 1 can be made stronger, and even if a screen door is provided on the upper surface, it will not cause any trouble. Never.

The mounting piece 5 provided on the lower surface of the overhang 3 is
It is arranged to extend downwardly from the lower surface of the uppermost end of the overhanging part 3, that is, from the connecting part with the lowermost end of the connecting part 2, and the lower end part 5a is formed in a bifurcated shape to form a hanging wall. It is designed to lock and abut against the horizontal projecting piece 14 of No. 11. Next, a screw 6 is screwed upwardly from the approximate center of the mounting piece 5, and in the case of this embodiment, it penetrates the hanging wall 11 of the sash lower frame 10 and is fixed to the window sill 20. be. Like this hanging wall 1
By passing the screws 1 through, the draining member 1 and the sash lower frame 10 can be more firmly attached. In addition, since the lower end 5a of the mounting piece 5 is locked to the horizontal projecting piece 14 of the hanging wall 11, the draining member 1 can be firmly attached to the sash lower frame 10, and the mounting piece 5 can be connected to the above-mentioned connecting portion. 2 extends from the upper end of the lower surface of the overhanging part 3, which is the lower end of the mounting piece 5, so that even if a screen door is provided on the connecting part 2, it can sufficiently support the weight of the screen door.
It is also possible to extend linearly without having a bifurcated shape, and to contact the base of the horizontal projecting piece 14 of the hanging wall 11.

In addition, each of the above-mentioned draining members 1 and sash lower frame 1
0 is mainly molded from an extruded material such as aluminum.

As described above, the present invention fixes the drain member to the window sill by fixing the mounting piece whose outdoor side is shielded with screws instead of attaching the connecting part of the drain member facing the outdoor side with screws. By doing so, it is possible to reliably eliminate rainwater intrusion from the screw fixing part as in the conventional case and improve rain protection. Moreover, since the screw fastening according to the present invention described above is made by screwing the screw from the inclined mounting piece to the window sill, the connecting part is pressed against the sash bottom frame by the horizontal pressing force of the screw. As a result, the airtightness of the joint between the draining member and the sash lower frame is improved, and rain protection can also be improved in this respect. Furthermore, since the connection part of the draining member formed separately from the sash bottom frame is pressed against the sash bottom frame at a position that covers the attachment part of the sash bottom frame hanging wall to the outdoor side of the window sill, the hanging wall is The screw fastening part is covered by the connecting part, and it is possible to reliably prevent rainwater or the like from entering the fastening part.
