Description

[Detailed Description of the Invention] The present invention relates to a window sash frame made by retrofitting a shutter frame to an existing indoor sash frame.

Conventionally, window sash frames are made by retrofitting a shutter frame to an existing indoor sash frame. It is connected.

This is preferable in terms of workability and installation strength, and is commonly used when retrofitting a shutter frame to an existing sash frame.

However, in this case, after the storm door frame is retrofitted, the upper screen door rail cannot be used as a screen door rail due to attachments, etc., and the screen door cannot be attached, which is inconvenient.

The present invention has been developed in view of the above circumstances, and its purpose is to provide a window sash frame in which a screen door can be attached after a shutter frame is retrofitted to an existing indoor sash frame.

It is at the same position in the indoor/outdoor direction as a.

On the outdoor side of the lower frame 2, a lower screen door rail 2a and an outdoor side wall 2b are vertically continuous and integrally formed, and the lower screen door rail 2a is at the same position as the upper screen door rail 1a in the indoor-outdoor direction, A vertical piece 5a of a lower attachment 5 is fixed to the outdoor side surface of the indoor wall 2b with screws 5b.

The shutter lower frame 20 is bent into a step-like shape by an upper wall 20a, a vertical wall 20b, and a lower wall 20c, and the upper wall 20
The vertical piece 22a of the L-shaped mounting body 22 is engaged with the concave groove 21 formed at the lower part of the frame 2, and the horizontal piece 22b thereof is placed on the horizontal piece 5c of the lower attachment 5 and is attached to the outdoor side surface of the lower frame 2. 2c, the upper wall 20a, the horizontal piece 2
The shutter lower frame 20 is attached to the lower frame 2 by tightening and fixing the horizontal pieces 2b and 5c with screws 23.

A recess 6a of a vertical attachment 6 is engaged with the outdoor wall 3a of the vertical frame 3, and the vertical attachment 6 is fixed to the outdoor side of the outdoor wall 3a with a screw 3b. A mounting piece 6b that is inclined is integrally formed.

The vertical shutter frame 30 is installed on the indoor and outer walls 30a, 30.
b and a connecting wall 30c, the indoor wall 30a is provided with a groove 31, and the outdoor wall 30b is provided with a groove 32 and a hollow frame portion 33.

Then, the mounting piece 6b is brought into contact with the inclined indoor side surface 34a of the mounting body 34 fitted in the concave groove 31 and connected and fixed with the screw 6c.
0 is attached to the vertical frame 3.

The folding shutter E includes first and second shutters E ₁ and E ₂ which are pivotally connected so as to be foldable, and the first shutter E ₁ is connected to the hollow frame portion 33 of the vertical shutter frame 30 via a hinge 40. The second shutter E ₂ is provided with a guide roller 41 and a guide pin 42 that protrude vertically, and the guide roller 41 is attached to the lower wall 2 of the lower shutter frame 20.
Insert the guide pin 42 into the guide groove 24 formed at 0c.
are slidably fitted into guide grooves 14 formed in the lower wall 10b of the shutter upper frame 10, and the first and second shutters E1 _and E are respectively fitted in the shutter upper frame 10 and the shutter lower frame 20. Upper and lower guide bodies 43 and 44 are attached to serve as guides when rotating ₂ laterally.

As a result, the folding shutter E is the first and second shutter.
Opening and closing operations are performed with E ₁ and E ₂ extended to the outside and bent.

In addition, the screen door G is attached to the upper screen door rail 1 of the shutter upper frame 10.
1 and the lower screen door rail 2a of the lower frame 2.

In the middle part between the indoor side and the outdoor side of the shutter upper frame 10, the lower shutter frame 20, and the vertical shutter frame 30 of the outdoor shutter frame _C2 (that is, the part between the shutter E and the screen door G), Handrail member attachment parts 10', 20', and 30' are formed that are wider than the handrail F serving as a handrail member, and the handrail member attachment parts 3 of the left and right vertical frames 30, 30 of the shutter are formed.
