Description

[Detailed explanation of the invention] Industrial applications: Recent window structures in buildings are designed to save energy, heat insulation,
Various efforts have been made to meet a variety of purposes such as soundproofing, and efforts are being made to improve performance and precision in the combination of double-glazed windows and rotating shoji screens. This proposal is a proposal to facilitate the production of window frames and to easily assemble highly accurate window frames in accordance with the above-mentioned objectives.

Conventional technology: Extruded aluminum alloy sections are usually used as the constituent members of these windows, and a wide variety of extruded section shapes have been put into practical use depending on the type of window. However, when assembling a window frame, it is necessary to interpose other auxiliary members, for example, to connect the upper, lower, left and right vertical frames, and to secure the door stop member, and it is necessary to insert holes in the mating member to be joined. The current situation is that we are forced to perform complicated and double-labor work, such as applying internal thread processing after processing. Particularly when assembling highly accurate window frames, extremely accurate measurements are required for determining the dimensions of the internal threads.

The problem that the invention attempts to solve: The main idea is as follows.
This is an improvement on issues (i) to (v). That is, (i) in the present invention, when assembling the window frame, auxiliary members such as corner pieces are not interposed at the four corners of the rectangular frame as in the conventional method.

(ii) Use only self-tapping screws to attach doorstop members, and do not use auxiliary members such as nuts.

(iii) All members are simply drilled with a drill, etc., and there is no need to further process internal threads with a tapper.

(iv) Each of the frame members forming the four sides is provided with a deep groove female screw seat at the same distance from the indoor side surface, so that the inner and outer surfaces of the window frame can be made flush with a simple assembly process.

(v) It is versatile and can be used for horizontal axis, vertical axis rotating windows, and various casement window frames.

Means for solving the problem: A rectangular window frame consisting of upper, lower, left and right vertical frames, and the flat part of the web of each frame closer to the room is equidistant from the indoor wall surface forming the same plane. A deep groove portion is provided along the longitudinal direction of each frame on the same vertical plane parallel to the window surface and having an opening of the same width, and the deep groove portion is connected to an opposing wall and a bottom portion that provide an internal screw seat during assembly. The depth thereof is sufficiently deep compared to the opening of the opening and is at least twice the root diameter of the female screw seat, and a tapping hole groove is formed deep along the spine side of the bottom. The main feature is window frames formed in series in the horizontal direction.

Effects and Examples: To explain in detail an example in which the configuration of the present invention is applied to a window frame for a horizontal axis rotating window, Figures 1 and 2 are an interior front view and an exterior front view of the window frame, and Figures 3 and 4 are a front view of the interior and exterior of the window frame.

A door stop member 8a, 8b, 8d or 8 is attached to either the left or right half of the upper frame 4 or the lower frame 7 of the window frame 1a shown in FIG. 5, and to the left or right vertical frame.
If a, 8c, and 8d are fixed, the window frame of the vertical rotating window shown in FIG. 10 will be obtained. If you attach hinges to both the left and right vertical frames of the window frame 1a, you will get a double-hung window that supports the shoji 2 as shown in Figure 11, and if you attach hinges to the right frame, you will get a single-hung window and lower frame as shown in Figure 12. If a hinge is attached to 7, a folding window as shown in FIG. 13 will be formed, and if a hinge is attached to upper frame 4, a flip-up window as shown in FIG. 14 will be formed.

Effects of the invention: In the present invention, when assembling the window frame, there is no need to provide auxiliary members such as corner pieces at the four corners of the rectangular frame as in the conventional case. In other words, each frame material forming the four sides has a female screw seat at an equal distance from the indoor wall surface, so the vertical frame and the upper and lower frames can be connected with screws to the predetermined female screw seats, making assembly easy. It will be done. When attaching the door stop member, only tapping screws are used to fix and support the female screw seat in the deep groove on the window frame side, so there is no need for auxiliary members such as nuts. The depth of the deep groove is more than twice the diameter of the female thread root, so it functions as a female thread in terms of strength, and all the parts need to be drilled, and the female thread can be formed using a tapper. It does not need to be applied. It can also be applied to multipurpose window frames.
