This relates to a window frame mounting device in which a wedge material 21 is driven into a wedge material driving portion A formed by the above.

Conventionally, it has been known to attach a new window frame 1 to an old window frame 16 using a plurality of metal fittings. For example, it is mounted as shown in FIG. 1 using metal fittings as shown in FIG. Because of this configuration, the height H of the box-shaped metal fitting 22 had to be increased, which caused the problem that the opening of the new window frame 1 became narrower. Furthermore, since the slide fitting 23 is only slidable against the sliding fitting 4 and is not fixed to the sliding fitting 4,
There was a problem that the mounting strength of this part was also weak.

The present invention was devised in view of the above points.The purpose of this invention is to reduce the height of the mounting bracket, to enlarge the opening of the window frame, and to firmly fix the mounting bracket to the sliding bracket. It is possible to provide a window frame mounting device.

The present invention will be explained in detail below with reference to Examples. An outdoor vertical wall 3 is provided on the outdoor side of the frame body 2 of the window frame 1 at the backs of the upper frame 2a and both side frames 2b, and the backs of the upper frame 2a and both side frames 2b have an L-shaped cross section. The L-shaped portion is provided with an engaging portion 24 extending in the longitudinal direction of the L-shaped portion. Here, the outdoor vertical wall 3 may be formed integrally with the upper frame 2a and both side frames 2b, or may be formed separately and fixed with a fixing tool. An engaged portion 25 of a substantially L-shaped sliding fitting 4 is slidably engaged with an engaging portion 24 provided in an L-shaped portion of the frame body 2 . The approximately L-shaped sliding fitting 4 is composed of a front piece 5 and a side piece 14, and a female screw hole 26 is bored in the front piece 5 facing the outdoor vertical wall 3 so as to be biased toward the side end. , the male threaded portion 27 of the bolt body 6 is screwed into the female threaded hole portion 26 so as to be freely shallow or deep. A pair of flanges 28 are provided on the bolt body 6, and the body portion 20 is formed by fitting between the flanges 28. An operating portion 29 for rotating the bolt body 6 with a jig is provided at the end of the bolt body 6 opposite to the male threaded portion 27. At the center of the side piece 14 of the sliding fitting 4, there is provided a concave curved strip 15 with a concave upper surface that becomes longer from the indoor side toward the outdoor side, and the lower surface side of the concave curved strip 15 becomes a convex strip 30. ing. In the figure, reference numeral 19 denotes a holding tool, in which projecting pieces 31 are provided inwardly projecting from both upper ends of the shaped part 32, and an engagement recess 33 is provided in the center of the bottom piece 32a of the shaped part 32. This clamping tool 19 is attached to the side piece 14 of the sliding metal fitting 4.
It is slidably fitted into the In the figure, reference numeral 10 denotes a mounting bracket, which connects an upper horizontal piece 7 and a lower horizontal piece 8 with a vertical piece 9, and has a substantially U-shape in the illustrated embodiment. A screw hole 11 is bored approximately in the center of the upper horizontal piece 7, and a notch 12 is provided near one side of the vertical piece 9 and opens laterally and does not reach the center. The horizontal piece 8 is provided with a concave groove 13 which is elongated from the indoor end toward the outdoor side and has a concave lower surface. The window frame 1 is installed in the following manner. That is, the male threaded body 18 is provided protrudingly at an arbitrary position on the old window frame 16 or the window mounting base 17. In the illustrated embodiment, the male threaded body 18 has an auxiliary fitting 49 attached to the old window frame 16, and the male threaded body 18, which is a screw tool, protrudes from the auxiliary fitting 49. Here, an anchor bolt serving as the male threaded body 18 may be driven into the window mounting base 17. The screw hole 11 of the mounting bracket 10 is screwed into the male threaded body 18, and the sliding bracket 4 is slid along the longitudinal direction of the frame 2, and a tool such as a screwdriver, wrench, etc. Fit the tool from the indoor side, rotate the bolt body 6, fit it, and make the cut 1 in the body part 20.
In this state, fit the body part 20 into the notch 12 in accordance with step 2, and then insert the side piece 1 of the sliding fitting 4.
The lower horizontal piece 8 and the side piece 14 are held together by the gripping tool 19, which has been positioned at the indoor end of the housing 4. At this time, the engagement recess 33 of the clamp holder 19 engages with the convex line 30 of the side piece 14, and the concave curved line 15 of the side piece 14 and the concave groove line 13 of the lower horizontal piece 8 are opposed to each other. A protruding wedge material driving portion A is formed by the curved line 15 and the grooved line 13. A wedge material 21 is driven into this wedge material driving portion A from the indoor side to fix the side piece 14 and the lower horizontal piece 8. Both the concave curved line 15 and the concave groove line 13 are deep on the indoor side and become shallower toward the outdoor side. By the way, the bolt body 6 is located laterally than the male threaded body 18 when viewed from inside the room, and as a result, the bolt body 6 and the male threaded body 18 do not intersect, and the installation shown in FIG. 7 is not possible. The height of the metal fitting 10 can be lowered, and the opening of the window frame 1 can be made larger.
In this way, the old window frame 16 or the window frame mounting base 17
With the upper frame body 2a and side frame body 2b of the window frame 1 attached and suspended, the lower connecting fitting 34 is attached to the lower frame body 2c.
to fix. Here, the upper vertical piece 35 of the lower connecting fitting 34
A part of the upper part is cut and raised to form a cut-and-raised piece 36, and a locking hanging piece 37 of the lower frame body 2c is locked between this cut-and-raised piece 36 and the upper vertical piece 35, The locking hanging piece 37 and the cut-and-raised piece 36 are fixed together from the indoor side using a fixing tool 38. In this way, the fixing device 38 does not protrude outside from the rising piece 39 of the lower frame body 2c, and rainwater does not enter the room from the fixed portion. A bolt 41 is screwed into the bottom piece 40 of the lower connecting fitting 34. Rotate the bolt 41 to press the head 42 against the old window frame 16 or the window frame mounting base 17, and in this state, remove the fixing fitting. 43 is inserted into the bolt 41, the fixture 43 is secured by the fixture 38, and the head 42 of the bolt 41 is clamped. The space between the window frame 1 and the old window frame 16 or the window frame mounting base 17 is filled with foamed synthetic resin B. Reference numeral 45 denotes an inner side frame having a substantially L-shaped cross section, and is attached by removably locking a locked portion 47 to a hook locking portion 43 provided on the window frame 1. Further, 48 is a rain shield plate attached to the lower frame body 2c.

In the case of the present invention, as described above, a screw hole is drilled in the center of the upper horizontal piece of the mounting bracket, and a notch is made that opens laterally near one side of the vertical piece and does not reach the center. Since the bolt body is shifted to the side compared to the male threaded body when viewed from the room, the bolt body and the male threaded body are not perpendicular to each other, and as a result, the height of the mounting bracket can be lowered by that much. The gap between the old window frame or the window mounting base and the window frame can be narrowed, and the size of the opening in the window frame can be increased. In addition, since the sliding fitting is slidably attached along the longitudinal direction of the frame, regardless of the protruding position of the male threaded body,
The sliding fitting can be reliably slid on the side of the male threaded body, and the bolt body is screwed in the front in any depth or depth, so by adjusting the screwing depth, the position of the fitting body in the window inside and outside direction can be adjusted. It is possible to fit the body into the notch securely by adjusting the depth of the screw, and since the threaded hole of the mounting bracket is screwed into the male threaded body, adjusting the depth of threading allows the body to fit into the notch securely. The protrusion length from the old window frame or window mounting base can be adjusted. Furthermore, the lower horizontal piece and the side piece are held by a clamping tool that is slidably attached to the side piece, and the fitting body of the bolt body is fitted into the notch, which is formed by opposing concave curved lines and concave groove lines. Since the wedge material is driven into the wedge material driving part,
The mounting bracket attached to the male screw body and the sliding bracket attached to the window frame can be firmly fixed, and the window frame can be firmly attached.
