Abstract

(57) [Abstract] [PROBLEMS] To provide a drainer for a sash that does not stain or rot the outer wall of a building to ensure drainage. SOLUTION: In a sash in which a drain member to the outside is inclinedly connected to a lower frame of a window frame, and a water piece that bends downward is provided at the lower end of the drain member, the drain member has a water piece on the back side from the water piece. A back cover piece was hung vertically across a space, and a caulking material was filled between the outer wall of the building and the back cover piece. [Effect] In the drainage member connected to the lower frame of the sash, since the back cover piece hangs across the space from the water section at the lower end, draining is ensured and rainwater drainage is never transmitted to the caulking material. Since it does not exist, there is no inconvenience that rainwater drained from the sash travels along the outer wall and stains its surface, or enters the outer wall to accelerate its decay.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a drainer provided at the lower end of a window frame in a sash made of aluminum or the like.

[0002]

[Prior art]

 In the sash, as a means for preventing the intrusion of wind and rain, as shown in FIG. 4, the lower frame 42 of the window frame is gradually formed outward in the cross section, and the standing wall 44 is provided at the outermost end as a wind and rain barrier. It stands upright (its end is cut away for drainage), and further, a mounting piece 46 is hung on the back side near the outside, and a draining member 48 for drainage is screwed to the mounting piece 46.

The draining member 48 is attached to the outside with a low inclination. A water piece 50 is bent at the lower end and hangs down, and a screwing cover for the mounting piece 46 of the lower frame is provided at the base end at the upper end. The mounting piece 52 is formed upward. A caulking material 56 is filled between the water section 50 and the outer wall 54 of the building so that rainwater does not enter.

[0004]

[Problems to be solved by the device]

 According to the conventional water draining device in the sash as described above, due to the filling of the caulking material 56, wind and rain will not be blown between the water piece 50 and the building outer wall W, but the rainwater flowing down the water piece 50 will not be blown. A part of it goes around to the back side and flows along the outer surface of the building outer wall 54 along the caulking material 56, which makes the outer surface unsightly and dirty, and especially between the outer wall 54 of the building and the caulking material 56 over time. If there is a small gap in the area, rainwater will penetrate into the interior of the exterior wall and accelerate the decay of the building.

In this regard, when the water piece 50 is hung down for a long time so that rainwater does not go around to the back, this problem is solved to some extent, but the work of filling the caulking material 56 becomes difficult. There is.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a drainer for a sash that does not stain or rot the outer wall of the building in order to ensure drainage.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a sash in which a drainage member to the outside is inclinedly connected to a lower frame of a window frame, and a water piece that bends downward is provided at the lower end of the drainage member. As for the drainage member, a back cover piece was hung vertically on the back side with a space from the water section, and caulking material was filled between the outer wall of the building and the back cover piece to form a drainer for the sash.

In addition, regarding the attachment of the drainage member to the lower frame, the attachment portion of the drainage member is formed in a deep groove shape, the bottom portion thereof is provided with the tight material, and the attachment piece vertically attached to the back side of the lower frame is attached. It is more effective to achieve the purpose if the mounting part is inserted and screwed.

[0009]

[Operation]

 Since the drainage device in the sash is configured as described above, the rainwater flowing down from the drainage member is surely drained from the water slice at the lower end of the drainage member, and the back cover piece is suspended across the space. Therefore, rainwater will never be transmitted to it. And, since caulking material is filled between the back cover and the outer wall, rainwater drained from the sash flows down the outer wall to stain its surface, or enters the outer wall to accelerate its decay. There is no such thing.

Regarding the attachment of the drainage member, since the deep groove-shaped portion to be attached is formed so as to sandwich the attachment piece of the lower frame, and the tight material is internally provided at the bottom, rainwater never enters from the attachment portion.

[0011]

Embodiment Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 and FIG. 2 show an example implemented in an aluminum sash. A drainer 3 is connected to a lower frame 1 of a window frame F to form a drainer. 6 and 6 are shoji that fit in the window frame F. Although it was implemented in a concrete building, it can be implemented in a wooden building with the same idea.

The lower frame 1 is formed so as to be gradually lowered toward the outside, and a standing wall 4 for preventing wind and rain is erected at the lower end of the lower frame 1, and an upper water section 5 for suspending rainwater is also erected, and further near the tip. A mounting piece 7 of the drainage member 3 is provided on the back side of the. Regarding the attachment of the lower frame 1 to the building frame, the anchor 8 fixed to the outer wall W of the building is assembled.

The drainage member 3 is provided with a mounted portion 9 in its angle setting so that the drainage member 3 can be mounted on the lower frame 1 at a steeper angle than in the conventional case, and the water section 11 is bent at the lower end as in the conventional case. In addition to hanging down, the back cover piece 13 hangs near it. Further, for attachment to the outer wall W, a dovetail groove 16 to be assembled with the attachment hardware 15 is provided on the back side as in the conventional case.

The attached portion 9 is a deep groove type having inner and outer-paired holding pieces 17 and 18 for sandwiching the attaching piece 7 of the lower frame 1, and is fixed by a screw 20 and attached to a retracted portion at the time of attachment. The baking material 21 is filled (FIG. 1). Further, the tight material 19 is dropped into the bottom of the groove of the attached portion 9, and the tight material 19 is held down by the attaching piece 7, whereby the tightness is enhanced.

Since the drainage member 3 has a steep slope, the attached portion 9 has a deep groove shape, and the weight member 19 is fitted on the bottom of the drainage member 3, there are mainly three elements. Even if the connecting recess of the member 3 is not filled with the caulking material 21, it is possible to reliably prevent rainwater from entering. Further, since the slope is steep, drainage at the lower end of the drainage member 3 is improved. Further, the deep groove shape of the attached portion 9 firmly and stably attaches the drainage member 3 to the lower frame 1, so that the drainage member 3 is reliably prevented from falling off even if the slope is steep.

At the lower end of the drainage member 3, since the space 23 is held between the water piece 11 and the back cover piece 13, the rainwater flowing down on the drainage member 3 is surely flowed from the water piece 11. The flow does not divert to the back cover piece 13. Since the back cover piece 13 is exposed to the outside of the outer wall W and is filled with the caulking material 25 in the meantime, rainwater travels through the caulking material 25 and spreads to the outer surface of the outer wall W, It does not infiltrate inside. Further, a tight material 26 is adhered to the back side of the drainage member 3 inside the back concealment piece 13, which also enhances the tightness.

FIG. 3 shows another embodiment of the drainage member 3. In the above embodiment, the water piece 11 and the back cover piece 13 are arranged so that their lower ends have the same height. The concealed piece 13 is shortened and the lower end is set high to enhance the effect of rainwater on the back hidden piece 13. Further, the attached portion 9 at the upper end is formed in a simple piece as in the conventional one.

[0019]

[Effect of the invention]

 As described above, according to the present invention, in the drainage member connected to the lower frame of the sash, since the back cover piece is hung down from the water piece at the lower end with a space in between, the drainage is sure and the caulking material is made. Since the drainage rainwater is never transmitted to the sash, it has the excellent effect of eliminating the inconvenience of rainwater drained from the sash being transmitted along the outer wall to stain its surface or to enter the outer wall and accelerate its decay. .

Regarding the attachment of the drainage member, a deep groove-shaped portion to be attached is formed so as to sandwich the attachment piece of the lower frame (Claim 2), and a tight material is provided inside the bottom portion thereof, so that rainwater enters from the attachment portion. Therefore, even if the work of filling the caulking material in the mounting part is omitted or forgotten, rainwater can be effectively prevented from entering. Further, since the drainage member is firmly attached, it is easy in terms of strength to drain it well and make it steep.
