Description

[Detailed description of the invention] This invention relates to the lower frame of a revolving window, and its purpose is to maintain a stable state without shaking the revolving window main body and the lower frame even when strong wind pressure is applied to the window part. The goal is to provide a lower frame for the.

As a lower frame of a revolving window, the one described in Japanese Utility Model Application No. 53-88045 is known (Utility Model Application No. 53-88045).
(See Figures 1 and 2 of Publication No. 8045).

These lower frames are effective in terms of watertightness and ease of attaching the hinge. an outwardly facing groove opening into the groove, and the hinge is fixed on the bottom wall of the upwardly facing groove.

Since the upward groove part also has an outward groove part at the bottom, the strength of the upward groove part alone is weak and cannot support the rotary window main body.

Therefore, conventionally, a support member for supporting the upward groove is disposed within the opening of the outward groove.

However, this support member is only designed for downward loads (although, in the embodiment shown in FIG. 2 in particular, it is movable in an upward direction).

Therefore, when strong wind pressure is applied to such a revolving window, the revolving window main body is pushed indoors and outdoors because the mounting part of the hinge that supports the revolving window main body, that is, the lower frame, is hanging from the hinge. When the hinge mounting part of the lower frame is lifted up.

However, when the hinge mounting portion swings like this, there is a drawback that the lower frame may be damaged or the hinge mounting screws may become loose.

Thus, this invention was devised to solve the above-mentioned conventional problems, and will be explained below based on the embodiments shown in the drawings.

In FIG. 1, the symbol A indicates the lower frame of the rotating window.

The lower frame A of the rotary window is formed with an upward groove 1 that opens upward, and an outward groove 3 that opens outward at the lower part of the bottom wall 2 of the upward groove 1.

A hinge 4 that rotatably supports the window body B is fixed to the bottom wall of the upward groove 1 with screws 5.

Reference numeral C indicates a support member.

The support member C is formed from a hanging piece 6 and a horizontal piece 7 in an oval shape.

This support member C has its horizontal piece 7 attached to the back side of the bottom wall 2 of the upward groove part 1, and the hanging piece 6 extends between the upper and lower parts of the outward groove part 3, and between its upper and lower ends 8.8 and the outer groove part 3. An engaging portion 11 in which the upper and lower pieces 9, 9 are provided facing each other.
... are engaged and fixed, respectively.

The support member C is attached to the back side of the bottom wall 2 of the upward groove 1 by means of screws 5 which fix the hinge 4.

Furthermore, a back plate 10 of the hinge 4 is attached to the back surface of the support member C.

Note that reference numeral 12 is a drain hole provided in the bottom wall of the upward groove portion 1 of the lower frame A.

When installing the support member C, slide it into the lower frame A of the rotary window from the longitudinal end, and connect the upper and lower ends 8, 8 of the hanging piece 6 and the outer groove 3 between the upper and lower parts of the outward groove 3. The upper and lower pieces 9 engage with engaging portions 11 provided opposite to each other.

After that, it may be fixed to the back side of the bottom wall 2 with screws 5.

Thus, this idea consists of the above structure.

According to this invention, the following effects are achieved.

i The support member is attached by the upper and lower ends of the hanging piece and the upper and lower both walls of the outward groove portion being engaged by the retaining portions provided facing each other, so that the lower frame can be secured even under strong winds. The upward groove will remain stable without lifting up.

ii The horizontal piece in the support member serves as a reinforcing member for attaching the hinge, and can increase the strength of the hinge attachment.
