Description

[Detailed description of the invention] This invention relates to a device for replacing window frames, and more specifically, when installing a new window frame on a building base without removing the old window frame, The purpose of this device is to provide a simple device that can efficiently and precisely fit the frame into the idle frame. In a device for fitting and attaching a new square-framed aluminum window frame to an old window frame, a rotary cam body having a pivot point and a curved cam surface that gradually moves away from the pivot point, In addition to being pivotally supported on either the old window frame or the new window frame, the new window frame or the old window frame is provided with a fixed cam body that opposes the rotating cam body, and the new window frame can be inserted by rotating the rotating cam body. The point is that the amount is configured to be adjusted.

The invention will be explained below with reference to each side shown.

Figure 1 is a front view of a window renovated using the device of this invention, seen from the indoor side.
3, and a cross section taken along line 2--2 in FIG. 2 is shown in FIG.

In the upper frame part shown in FIG. 1, 1 is a building base;
2 is the upper frame of the steel drafting window frame that remains on this base 1.

Reference numeral 3 is a new aluminum window frame material, and the top part thereof has longitudinal grooves 3a, 3 through the parts corresponding to the indoor side and the outdoor side.
a is formed, and a through-shaped decorative material 3b is integrally formed on the outside of the top room so as to protrude upward.

A piece-shaped anchor fitting 4 is attached to the upper part of the upper frame member 3 of the new window frame using the grooves 3a, 3a, and can be attached and detached by twisting it in a plane.

A fixed cam body 1o in the form of a short strip facing in the longitudinal direction of the window frame is integrally formed in the metal fitting 4 in an upright shape.

On the other hand, a mounting base 5 is fixed (or integrated by welding) to the side of the slotted frame that approximately corresponds to the anchor fitting 4 through the bottom of the upper frame 2, and a vertical pivot shaft is attached to the indoor side of this base 5. 6 is provided.

This pivot 6 is equipped with a rotary cam body 7 formed in a fan shape so as to be horizontally rotatable. The cam surface 7a is shaped.

As shown in Fig. 3, the part of this cam surface 7a that is closest to the pivot shaft 6 rotates on the trajectory indicated by arrow a, while the part farthest from it rotates on a large trajectory as indicated by arrow A. There is a difference of about the size, and this is exactly the cam surface 7.
Since the fixed cam body 10 that is in contact with the front side of a is pushed toward the outside, the amount by which the old window frame fits into the new window frame can be changed.

These devices are also attached to the vertical frame parts other than the upper frame part, and by adjusting these parts in a balanced manner as a whole, it is possible to achieve the desired state of conformity.
The lock piece 11 is screwed in to fix it three-dimensionally.

Of course, in such a case, a sealing material 12 is interposed between the decorative material 3b and the old window frame/base 1, and a fixing frame is ultimately attached to the indoor side.

Regarding other types, for example, the one shown in FIG. 4 is one in which the fixed cam body 10 is placed on the side of the old window frame where the mounting base 5 is located, and the rotary cam body 7 is placed on the side of the new window frame.

The one shown in FIG. 5 is similar to the one shown in FIG. 4 without the anchor fitting 4.

Furthermore, the one shown in FIG. 6 similarly eliminates the anchor fitting 4, and has a fixed cam body 10 directly planted on the new window frame and a rotary cam body 7 placed on the old window frame side, and employs these various methods.

Further, as shown in FIGS. 7 and 8, the cam surface 7a is formed on the inner surface of the rotary cam body 7, and a pin-type or plate-type fixed cam body 10 is drawn into the cam surface 7a. The device can be configured not only by an extrusion method but also by a retraction method.

This idea is as described above, and therefore, when a new window frame is installed inside the fenestration frame without removing the old window frame already installed on the building base, it is possible to efficiently and efficiently fit the new window frame into the fenestration frame. This allows for accurate adjustment, which can be achieved at low cost with an extremely simple device, and in particular, by converting the rotation of the cam body into forward and backward movement of the new window frame, it can be easily adjusted even by ordinary workers. Not only is the cam body advantageous in that it can be adjusted, but also after adjustment, the cam body acts as a reinforcing device and contributes to ensuring the stability of the new window frame.
