[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain device for a sash window which is attached to the sash frame so as to extend over the outside and the outer periphery of the sash frame.

[0002]

2. Description of the Related Art When attaching a sash window to an opening of a sash window, rainwater permeates into the sash window from an attachment portion of the sash window,
In order to prevent dew from forming on the outer wall components in winter, various waterproofing processes have been applied to the window mounting portion, and the development of outer wall materials free from dew condensation has been attempted. (For example, 63-46503
On the other hand, much of the rainwater that has penetrated into the skeleton and the dew condensation generated in the components of the outer wall are drained outside using the upper frame material and vertical frame material of the sash frame. Have been.

[0003]

[Problems to be Solved by the Invention] In the case of conventional sash windows, it is extremely difficult to repair rainwater that has penetrated into the skeleton from the window mounting portion or that dew water has formed on the components of the outer wall. However, there was a problem that sash windows and outer wall materials often had to be replaced. Also, even if drain holes or drain holes for rainwater that has penetrated into the body from outside or dew condensation water generated in the outer wall components are provided in the sash window, the drain holes will be damaged or the drain function will be defective. In such a case, there was a problem that the sash frame had to be replaced. The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to remove rainwater that penetrates into a frame from a window mounting portion and dew water generated in components of an outer wall by sash. An object of the present invention is to provide a drainage device that can be separated from a frame and drained.

[0004]

In order to achieve the above object, a drain device for a sash window according to the present invention comprises an upper member for mounting a drain frame attached to the outdoor side of a sash frame to an upper frame member via an auxiliary member. And a lower member attached to the lower frame member, and a side member attached to the vertical frame member via an auxiliary member. The upper member has a hook-shaped cavity facing the room, and is collected at an upper portion of the cavity on the indoor side. While the water block is mounted, a drain hole is formed in the lower part of the outside of the cavity, and a hollow part is formed by the side member and the auxiliary material to communicate with the drain hole of the hook-shaped cavity.

Part 7
A water collecting block 6 is attached to the upper part of the inside of the cavity 7 on the indoor side, and a drain hole 22 is formed in the lower part of the outside of the cavity 7 outside the room. The hollow portion 8 communicating with the drain hole 22 is formed.

[0007] The upper member 2 is a sloping wall which is inclined downward toward the outdoor.
A hanging wall 2b is provided on the outer edge of 2a and an upright wall 2c is provided on the inner edge, and the hanging wall is provided.
A horizontal wall 2d protrudes from the lower part of 2b toward the room, a stepped wall 2e is provided at an intermediate part of the horizontal wall 2d from an intermediate part of the inclined wall 2a, and a hook-shaped space facing the room and downward on the outside of the upper member 2. 7, a rising wall 2f is provided on the sloped wall 2a outside the stepped wall 2e from the hanging position, and an outward hooking wall 12 is formed on the indoor side of the horizontal wall 2d so as to be folded outward from the horizontal wall 2d. ing. And rising wall 2f and stepped wall
A hole 21 is formed in the inclined wall 2a between the two walls 2e, and a drain hole 22 is formed in the horizontal wall 2d on the outdoor side of the stepped wall 2e. is there.

The side member 4 has an inner peripheral wall 4b parallel to the main wall f3 of the sash vertical frame member F3 on the inner peripheral side of an outer peripheral wall 4a parallel to the hanging wall 2b of the upper member 2, and an inner peripheral wall on the outer peripheral side. An outer peripheral wall 4c wider than the peripheral wall width L is provided in parallel with the inner peripheral wall 4b, and an outward hook wall 14 is formed on the indoor side of the inner peripheral wall 4b so as to be turned outward from the inner peripheral wall 4b. The mounting wall 4d protrudes in the direction.

The lower member 3 is provided with a downward wall 3b parallel to the hanging wall 2b of the upper member 2 at the front end of a drain wall 3a inclined downward toward the outside of the room, and a sash lower frame member F2 at the rear end. The vertical wall 3c circumscribing the downward piece f2 is formed. Water collecting block 6
