However, when attaching the inner plates 4, 5, and 6, the attachment members 4a, 5a, and 6a are used, and in the case of the vertical frame 6, an auxiliary member 6b for attaching the attachment member 6a is also used.

Both ends of the inner plates 4, 5, and 6 are cut at an inclination angle of 45 degrees, and the vertical and horizontal sides are butted against each other with the cut end surfaces, and are connected by an L-shaped connecting block 14, and the inner plates 4, 5, and 6 constitutes a picture frame G. Therefore, each inner plate 4, 5, 6 has a connector 1.
Four insertion portions 15 are provided.

Next, regarding the shape of the inner plates 4, 5, and 6, the front wall 16 and the back wall 17 are connected by the indoor end wall 18, and the back wall 17 is made shorter than the front wall 16. In the surface wall 16, the interlocking pieces 21 overlapping with the projecting pieces 12 are formed at different levels,
The surface wall 16 and the protruding piece 12 are flush with each other. Further, the insertion portion 15 of the connecting block 14 is a space surrounded by the front and back walls 16, 17, the end wall 18, and the protrusions 19, 20, into which the connecting block 14 is tightly fitted. And the connecting block 14 is screw 4
0 to the inner plates 4, 5, 6, but since the connecting block 14 is interposed between the front and back walls 16, 17, even if the inner plates 4, 5, 6 are incompletely hollow bodies, Stability of the cross-sectional form at the end is obtained.

Furthermore, the inner plates 4, 5, 6 form engagement grooves 23 with the mounting members 4a, 5a, 6a by protruding an L-shaped bending piece 22 near the tip of the connecting piece 21, and A check claw 24 is provided at the tip of the wall 17,
A hanging strip 25 is formed at the tip of the protrusion 20 from the back wall 17 toward the outdoor side, and a through hole 55 for a screw 54 is provided at the tip of the back wall 17.

Next, the mounting members 4a, 5a, and 6a are approximately L-shaped bending plates with a main support piece 27 protruding from the end of the base piece 26.
A fairly short auxiliary support piece 28 is provided protruding parallel to 7. Furthermore, by forming a thick wall portion 29 at the tip of the main support piece 27, a step portion 39 that is hooked on the non-return claws 24 of the inner plates 4, 5, and 6 is provided. A slope 38 is formed to rub against the inside of 25 so that it can be easily inserted into the inside of 25. Also, the base piece 26
A through hole 57 for a screw 56 is provided at the center of the width, and a threaded hole 58 into which the screw 54 is screwed is provided in the thick portion 29.

Regarding the auxiliary material 6b attached to the vertical frame 3, it is used to supplement the width of the inner wall 11 of the vertical frame 3.

is provided. The auxiliary member 6b can be hung on the hooking pieces 31 by tilting it or moving it back and forth even after the window frame F is assembled.

Next, an example of the procedure for attaching the inner plates 4, 5, and 6 will be explained.

First, after attaching the window frame F to the opening X, attach the mounting material 4a to the upper frame 1 and the left and right vertical frames 3, 3.
5a and 6a are fixed with screws 56. On the other hand, the upper and lower inner plates 4 and 5 and the left and right inner plates 6 and 6 are connected by a connecting block 14 to assemble the picture frame G.

Next, move the picture frame G toward the window frame F from the indoor side, and connect the engagement groove 23 at the tip of the front wall 16 and the locking strip 25 at the tip of the back wall 17 to the sub-support pieces 28 and Thick wall part 29 at the tip of main support piece 27
Combine each.

In this state, the tips of the back walls 17 of the inner plates 4, 5, 6 are fixed with screws 54 to the tips of the main support pieces 27 of the mounting members 4a, 5a, 6a. Then, the engagement groove 23 at the tip of the difference piece 21 will not come off from the sub-support piece 28 of the mounting members 4a, 5a, 6a, and the state in which the difference piece 21 and the bending piece 22 are in surface contact with the sub-support piece 28 will be maintained. By maintaining this surface contact, the inner plates 4, 5, and 6 are prevented from wobbling.

Note that since the engagement between the check pawl 24 and the stepped portion 39 is maintained by the latching strip 25 holding down the thick portion 29, the screwing operation of the screw 54 is easy.

[Effects of the invention] As explained above, this invention attaches an inner plate made of extruded material such as aluminum to a sash frame whose cross-sectional shape is the same as that of the sash frame to which a wooden inner plate has conventionally been attached. In particular, when the width of the indoor side wall of the window frame to which the inner panel is attached is insufficient, by implementing the present invention, the installation is easy and the stability is good.

Furthermore, since the inner plate is formed into a partially hollow U-shaped cross section with a back wall shorter than the front wall, less material is required compared to a completely hollow structure, and the inner plate can be installed at a low cost. Moreover, the imperfections are hidden and the visible parts give the appearance of a board.
The appearance is very good.
