Description

DETAILED DESCRIPTION OF THE INVENTION When replacing existing old window frames with new window frames in various buildings, the present invention allows the old window frames to remain without being removed from the base of the building, and replaces the assembled new window frames with new ones. When implementing the window frame renovation method in which the window frame is fitted into the old window frame and the new window frame is attached to the old window frame, the upper frame (including the vertical frame) of the new window frame is attached to the upper frame of the old window frame. The present invention relates to the provision of a new mounting device for mounting on a vertical frame (including a vertical frame).

As is well known, window frames in older buildings are made of wood or iron, but these window frames have poor soundproofing performance and deteriorate due to long-term use, making it difficult to install new windows. The time has come to replace the window frame, and as is known, aluminum window frames are generally used as new window frames, and the conventional method for replacing them is to replace concrete at the opening of the window frame. It was removed by chiseling, the old window frame was removed, and the reinforcing bars were exposed.
Previous methods used to install new window frames using reinforcing bars, etc., but with this construction method, the entire work, including the installation of scaffolding, was extremely time-consuming in terms of equipment and labor, and it also generated noise. However, there are drawbacks such as restrictions on the use of buildings during construction, which are extremely inconvenient and costly. As an alternative to this, the applicant has proposed a shape that can be fitted into the old window frame while leaving the existing old window frame without removing it from the building base.
A new window frame refurbishment method involves manufacturing a new window frame with the same dimensions in advance and fitting the new window frame into the old window frame to connect it to the old window frame. Many proposals have been made and implemented regarding devices and appliances, but the present invention is particularly applicable to this window frame renovation method, especially for replacing the upper frame of an old window frame (including the vertical frame) with the upper frame of a new window frame. This is a new proposal that has been improved to make installation easier and more reliable, improve construction accuracy, and make work faster, more efficient, and labor-saving. is a window frame in which the existing old window frame remains without being removed from the building base, and a new window frame that has been assembled in advance is fitted into the old window frame to attach the new window frame to the old window frame. In the renovation method, a continuous fitting is a device for attaching the upper frame and/or vertical frame of old and new window frames to each other, and is fixed to one frame or installed so that it can move forward and backward in the longitudinal direction of the frame, and the other The locking metal fitting is provided on the frame so as to be movable forward and backward in the front and rear directions of the frame, and can be raised and lowered at that position, and is fixable to the continuous metal fitting.

This is the upper frame part of the new window frame, and needless to say, the left and right vertical frame parts are continuous from both ends of the upper frame 1 and upper frame 2 in the longitudinal direction (vertical direction in the drawing) for both the old and new window frames. Furthermore, the bottom frame part is continuous at both lower ends of the vertical frame part, making the whole window frame body square as seen in Figure 1.The new window frame is made in advance as an aluminum window frame body at the factory. It has already been assembled during production, and its dimensions are such that it can be fitted into the old window frame.The illustration shows installation of only the upper frame part, but it is similar to known Since the left and right vertical frame portions have substantially the same frame shape and structure as the upper frame portion, the mounting device of the present invention can be used not only for the upper frame portion shown, but also for mounting between the old and new window frames facing each other. It can also be applied as a mounting device.

In the illustrated example, the mounting device between the upper frame 2 and 3 of the present invention (including the vertical frame is the same hereinafter) is a continuous fitting 4 installed on the lower surface of the upper frame 2 of the old window frame, and a new window frame.

It can be adjusted and connected to the connecting portion 4b by means of a fastening screw 11 that can be drilled at that position. A split groove 10a is formed at one end of the shaft support 3a facing the indoor side of the threaded rod 10, so that the threaded rod 10 can be rotated in forward and reverse directions from the indoor side using a screwdriver or the like. In addition, in the illustrated example, the continuous joint fitting 4 is shown as a piece material that stays at a short length, but it may also be a continuous material that extends over the entire length in the longitudinal direction of the upper frame. Joint fitting 4 and locking fitting 5
are arranged in a row at appropriate intervals in the longitudinal direction. In addition, in the illustrated example, the threaded rod 10 that supports the locking metal fitting 5 so that it can move forward and backward is prevented from moving in the longitudinal direction by shaft supports 3a and 3b provided at fixed positions on both ends of the upper frame 3 in the front and rear directions. Although this is not shown, a separate holder plate equipped with shaft support holes 3a and 3b is provided, and this plate is slid in the longitudinal direction on the upper surface of the upper frame 3. It is also possible to provide it as possible.

In the modified embodiment shown in FIG. 4, the connecting fitting 4 is provided on the upper frame 3 side of the new window frame, and the locking fitting 5 is provided on the upper frame 2 side of the old window frame. In the case of this type, a shaft support hole 3 is provided on the lower surface of the old upper frame 2 to rotatably support both ends of the threaded rod 10, as shown in the figure.
The holder plate 12 with the screws a and 3b is fixed with screws or other fixing members 8, and the threaded rod 1
0 uses a headed bolt, and 10b indicates a head that is inserted and locked into one side of the shaft support hole 3a.

A connecting portion 4b that can be connected and fixed by a fastener 13 such as a nut is formed to protrude upward. Even in the case of this type, adjustment according to the height of the gap space between the upper frames 2 and 3 by freely raising and lowering the connecting piece 5b is the same. At this time, the continuous fitting 4 may be a piece material or a continuous material spanning the entire length. In the case of a continuous material, a plurality of connecting parts 4b are arranged in a row on the mounting part 4 corresponding to the installation position of the locking metal fitting 5. will be done.

What is shown in FIG. 5 is each modified example of the continuous joint fitting 4, and in the case of the illustrated example, each modified example of the metal fitting 4 of the type attached to the upper frame 2 side of the old window frame. The figure shows a horizontal U-shaped one in which a pair of connecting parts 4b, 4b are protruded in parallel from both ends of a mounting part 4a fixed to the upper frame 2 by a fixing member 8. Flange-shaped attachment parts 4a, 4a are formed at the lower ends of the pair of connecting parts 4b, 4b, and the connecting parts 4b, 4
The upper ends of b are shown closed by a connecting part 4e, and the figure shows the mounting part 4a, the connecting part 4b, and the connecting part 4b.
A U-shaped piece with a reinforcing part 4f running parallel to the mounting part 4a from the upper end is shown. The one shown in the figure uses a rectangular pipe-like square pipe fitting 4g as the continuous joint fitting 4, and the same fitting 4g is As shown in the figure, it is attached to the lower surface of the upper frame 2 using a mounting bolt 8a with a retaining structure, and the one shown in the figure is connected using a round tube fitting 4h instead of the square tube fitting 4g. In these pipe types, the peripheral surface serves as the attachment part and the connection part, and in the case shown in the same figure, the attachment part 4a and the connection part 4b are formed into a T shape. This modified example of the continuous joint fitting 4 is designed in consideration of the structural strength of the metal fitting 4, the convenience of installation due to the direction of the connecting piece 5b of the locking fitting 5, and the robustness of the connecting part structure. Any of these can be selected depending on the shape and structure of the upper frames 2 and 3 of the target window frame, the width of the upper and lower gaps, etc.

The attachment of the new window frame upper frame 3 to the old window frame upper frame 2 using the attachment device of the present invention is carried out as follows. That is, in the embodiments shown in FIGS. 2 and 3, the assembled new window frame is fitted into the old window frame remaining on the base 1, and the upper frame 3 of the new window frame is replaced with the upper frame 2 of the old window frame. At this time, by rotating the threaded rod 10 of the new upper frame 3 from the indoor side using a screwdriver or the like, the locking fitting 5 is moved straight back and forth via the threaded portion 5a, and thereby Therefore, the mounting position of the new upper frame 3 in the front-rear direction can be adjusted appropriately, and the connecting piece 5b of the metal fitting 5 is connected to the connecting part 4 of the continuous connecting metal fitting 4.
The new upper frame 3 can be fixed by drilling and fastening the fastening screws 11, but as previously explained in FIG. The connecting piece 5b can be raised and lowered using the upper and lower frames 2 and 3 as a fulcrum, and the connecting piece 5b can be fixed in an appropriate inclined or upright position depending on the height L of the gap space between the upper and lower frames 2 and 3. 3. Adjustment of the mounting position in the height direction and appropriate ratio are possible. At this time, if you want to adjust the new upper frame 3 in the longitudinal direction,
3b using a separate holder plate 12 as shown in the fourth figure, this holder plate 1
2 is provided on the upper surface of the new upper frame 3 so as to be movable in the longitudinal direction by utilizing the sliding structure seen in the mounting part 4a of the continuous joint fitting 4 in Fig. 4, the position in the longitudinal direction can be easily adjusted. It is.

Also, in the case of the embodiment shown in FIG. 4, the connecting fitting 4 is simply attached to the new upper frame 3 side and the locking fitting 5 is attached to the old upper frame 2 side, and the installation operation itself is essentially the same.
The position adjustment of the new upper frame 3 in the front-rear direction, height direction, and longitudinal direction can be performed by the same operation, such as moving the locking fitting 5 back and forth on the screw shaft 10, and moving the connecting piece 5b as a fulcrum of the spiral tube part 5a. Connecting portion 4b due to ups and downs slope
The same effect can be obtained by fastening the connecting fittings 4 to the upper frame 3 and sliding the connecting fittings 4 in the longitudinal direction on the upper frame 3.

The attachment of the upper frame of a new window frame to the upper frame of an old window frame using the attachment device of the present invention is superior to conventional attachment devices in the following points. That is, the device of the present invention has a locking metal fitting 5 that is movable forward and backward in one frame and can be tilted up and down at a set position, and a continuous metal fitting that is fixed or movable in the longitudinal direction on the other frame. 4, the new upper frame 3 can be properly installed quickly, easily and accurately almost in one touch, without the need for combinations of various mounting members or stepwise installation as in the past. At this time, the adjustment of the new upper frame 3 with respect to the old upper frame 2 in both the longitudinal direction and the height direction can be achieved at the same time by advancing and retracting the locking metal fitting 5 and rotating it in its advanced and retreating positions. This method is significantly advantageous in terms of reduction in the number of parts and ease of operation compared to systems that require separate operating members for each operation. Moreover, by using the threaded rod 10, the adjustment can be made very finely and accurately, and the structure of the continuous fitting 4 can be significantly simplified.
This enables the overall structure of the device to be simple, allowing it to be compactly stored and installed within the space between the upper frames 2 and 3, which is originally narrow. Only the parts are required, and manufacturing and assembly are extremely easy, and the overall installation work of the new window frame inside the old window frame is significantly speeded up.This installation device can also be used for the left and right rigid frames, making the work easier. Reduced man-hours,
It is particularly distinguished by the ease and speed of the adjustment operation, which at the same time allows for a cost-effective installation.
