First, the conventional device will be described. A window frame 3 is fixed inside a rectangular window opening 2 provided in the wall 1, and a window shovel 4 is built inside the window frame 3. On the indoor side surface of the wall 1 (right side surface in FIGS. 5 to 7), steel plate contact plates 5 and 5 are fixed to the peripheral portion of the window opening 2. Circular holes 6, 6 are formed in each of the contact plates 5, 5 so that the openings at one end of the nut pieces 7, 7 embedded in the wall 1 are aligned with the circular holes 6, 6. Further, bolts 8 and 8 are screwed to the other end portions of the nut pieces 7 and 7, and the bolts 8 and 8 are embedded in the concrete constituting the wall 1 to remove the nut pieces 7 and 7. I am trying to stop it.

Fixing brackets 10 and 10 are fixed to the indoor side surface of the wall 1 by bolts 9 and 9 screwed to the nut pieces 7 and 7, respectively. Each of the fixing brackets 10 and 10 formed by bending a steel plate into an L shape has vertical fixing plate portions 10a and 10a and horizontal connecting plate portions 10b and 10b. Then, the indoor end portions of the connecting plates 11 and 11 are respectively coupled and fixed to the connecting plate portions 10b and 10b by studs 12a or bolts 12b. Further, the outdoor end portions of these connecting plates 11, 11 are connected to the window frame 3.

The holes formed in the fixing plate portions 10a and 10a of the fixing brackets 10 and 10 for inserting the bolts 9 and 9 are elongated holes 19 and 19 which are long in the vertical direction. The mounting position can be freely adjusted in all directions. Further, among the holes formed in the connecting plate portions 10b, 10b of the fixing brackets 10, 10 for inserting the bolts 12, 12, the holes formed in the connecting plate portion 10b of the lower fixing bracket 10 are The long hole 20b is long in the left-right direction (front and back direction in FIGS. 5 and 7), and the mounting position can be freely adjusted in the left-right direction. On the other hand, the hole formed in the connecting plate portion 10b of the upper fixing bracket 10 is a long hole 20a that is long in the indoor / outdoor direction (the horizontal direction in FIGS. 5 to 7). Further, among the holes formed at the indoor ends of the connecting plates 11, 11 for inserting the bolts 12, 12, the holes formed in the lower connecting plate 11 are long holes that are long in the indoor and outdoor directions. 21, the mounting position in the indoor and outdoor directions can be freely adjusted.

[0006]

[Problems to be solved by the device]

 However, in the case of the conventional window frame supporting device configured as described above, there are the following problems to be solved. That is, in order to fix the fixing plate portions 10a and 10a of the respective fixing brackets 10 and 10, the contact plates 5 and 5 attached to the indoor side surface of the wall 1 are provided at the same time when the wall 1 is made by concrete pouring. Although it is attached to a part, this contact plate 5 may be inclined with respect to the vertical plane due to poor construction (see Fig. 4 showing an embodiment of the present invention).

When the contact plate 5 is inclined, the connecting plate portion 10b of the fixing bracket 10 fixed to the contact plate 5 is inclined with respect to the horizontal direction, and the connecting plate portion 10b is connected to the indoor end thereof. 11 is also inclined with respect to the horizontal direction. If both ends of the connecting plate 11 and the connecting plate portion 10b of the fixed bracket 10 and the window frame 3 are connected while leaving such a state as it is, an unreasonable force is applied to each connecting portion.

For this reason, conventionally, a shim is interposed between the connecting plate portion 10b of the fixed bracket 10 and the indoor end portion of the connecting plate 11 which are inclined with respect to the horizontal direction to prevent the connecting plate 11 from inclining. Was there. However, such an anti-tilt method using a shim is not preferable because the work of assembling the window frame supporting device is not only troublesome, but also the connecting strength of the connecting portion with the shim interposed tends to be insufficient. The support device for a window frame of the present invention is intended to eliminate the above-mentioned inconvenience.

[0009]

[Means for Solving the Problems]

 The window frame supporting device of the present invention includes a window frame, a fixing bracket fixed to an indoor side surface of a wall having an opening to fix the window frame inside, and the fixing bracket and the window frame. It consists of a connecting bracket.

Particularly, in the window frame supporting device of the present invention, the window frame is formed with a locking groove having an approximately C-shaped cross section and having an opening on the indoor side at an indoor edge thereof. The fixing bracket has an L-shape that includes a fixing plate portion that is fixedly connected to the indoor side surface of the wall, and a connecting plate portion that is bent from one end of the fixing plate portion toward the indoor side. Further, the above-mentioned coupling bracket has a locking ridge having a circular cross section formed on the outdoor edge, and by fitting this locking ridge into the above-mentioned locking groove, one end of the locking ridge is fitted to the window frame. It is swingably connected to the indoor edge. Further, the connecting bracket is connected to the connecting plate portion of the fixed bracket by a screw member.

[0011]

[Action]

 In the case of the window frame supporting device of the present invention configured as described above, the locking ridge is displaced inside the locking groove so that the window frame and the coupling bracket remain connected. The mounting angle between the window frame and the connecting bracket can be adjusted. Therefore, even if the mounting angle of the fixing bracket fixed to the indoor side surface of the wall deviates from the specified angle, the window frame is mounted on the wall without applying excessive force to each part or reducing the joint strength. You can

Embodiments FIGS. 1 to 4 show an embodiment of the present invention. A window frame 3a is fixed to the inside of a rectangular window opening 2 provided in the wall 1, and a glass panel 13 is built inside the window frame 3a to form a dead-fitting window. Abutting plates 5a, 5a made of a steel plate and having an L-shaped cross section are fixed to the indoor side peripheral edge of the window opening 2. Circular holes 6, 6 are formed in each of the contact plates 5a, 5a, and the one end openings of the nut pieces 7, 7 embedded in the wall 1 are aligned with the circular holes 6, 6. Further, bolts 8 and 8 are screwed to the other end portions of the nut pieces 7 and 7, and the bolts 8 and 8 are embedded in the concrete constituting the wall 1 to remove the nut pieces 7 and 7. I'm trying to stop it.

A locking groove 15 is formed on the indoor edge of the lower frame 14 that constitutes the lower side of the window frame 3a. The locking groove 15 has a substantially C-shaped cross section and opens on the indoor side, and the width dimension of the opening is smaller than the inner diameter dimension.

On the other hand, the fixed plate portion 10a of the fixed bracket 10 is fixed to the indoor side surface of the contact plate 5a fixed to the lower edge portion of the window opening 2. That is, the stud 16 screwed to the nut piece 7 is inserted into the vertically long slot 17 formed in the fixed plate portion 10a of the fixed bracket 10, and the tip of the stud 16 is fixed to the fixed plate portion. A nut 18 is screwed into a portion of the inner surface 10a protruding from the indoor side surface and further tightened. The connecting plate portion 10b of the fixing bracket 10 formed by bending a steel plate having sufficient rigidity into an L-shape has a length in the left-right direction (front and back directions in FIGS. 1, 2, 4 and vertical direction in FIG. 3). The hole 19 is formed.

The connecting bracket 22 for connecting the lower frame 14 and the fixed bracket 10 is formed by cutting an aluminum extrusion-molded material into an appropriate width dimension and further forming a long hole 20 for inserting a stud 23 described later. It is made by installing. A locking protrusion 24 having a circular cross section is formed on the outdoor edge of the connecting bracket 22. The outer diameter of the locking projection 24 is substantially the same as the inner diameter of the locking groove 15.

The locking projection 24 as described above is inserted into the locking groove 15 from the axial end opening of the locking groove 15. Therefore, the outdoor end of the connecting bracket 22 is slightly swingably connected to the indoor edge of the lower frame 14.

Further, the connecting bracket 22 and the connecting plate portion 10b of the fixed bracket 10 are connected by a stud 23 which is a screw member and nuts 25a and 25b screwed to the upper and lower end portions of the stud 23. There is.

In the case of the window frame supporting device of the present invention configured as described above, the locking ridge 24 is displaced inside the locking groove 15 so that the lower frame 14 constituting the window frame 3 a. The attachment angle between the lower frame 14 and the connection bracket 22 can be adjusted while the connection bracket 22 and the connection bracket 22 remain connected. Therefore, as shown in FIG. 1, when the contact plate 5a is properly mounted on the wall 1 and the fixing plate portion 10a of the fixing bracket 10 can be arranged in the vertical direction and the connecting plate portion 10b can be arranged in the horizontal direction, respectively. Of course, as shown in FIG. 4, even if the attaching plate 5a is not properly attached and the connecting plate portion 10b of the fixing bracket 10 is inclined with respect to the horizontal direction, an unreasonable force is applied to each portion, or the connecting plate portion 10b is connected. The lower frame 14 forming the window frame 3a can be attached to the wall 1 without lowering the strength.

In the case of the illustrated embodiment, as shown in FIG. 1, the upper frame 26 constituting the window frame 3a has a structure different from that of the window frame supporting device of the present invention. The window is formed on the upper side of the opening 2. That is, the fixing bracket 27 fixed to the indoor side surface of the wall 1 and the connecting bracket 28 by the bolt 29 and the nut 30 fixed to the indoor side surface of the upper frame 26 are connected by the bolt 31 and the nut 32. .

At the lower end of the fixing bracket 27, there is a bending plate portion in a portion hidden by the coupling bracket 28, and the bolt 31 is configured to overlap the bending plate portion and the coupling bracket 28. Are bound to. As described above, even with the structure in which the upper frame 26 is coupled to the wall 1, the inclination of the fixing bracket 27 due to the improper mounting of the contact plate 5a can be compensated, but the assembling and adjusting work becomes more troublesome than the case of the present invention. . Therefore, not only the lower frame 14 but also the upper frame 26 can be supported by the supporting device of the present invention.
