Description

[Detailed description of the invention] The present invention is a finish frame fixing device for a window frame opening, in particular, a finish frame that is installed in the opening of a building where a window frame is installed, and that is connected to the window frame and installed on the indoor side of the window frame. relates to a fixing device.

Generally, when a window frame is attached to the window frame opening of a building, the structural members such as columns that make up the building frame and the ends of interior materials are exposed on the indoor side of the window frame.
A finished frame is provided on the indoor side of the window frame of the opening. For example, as shown in FIGS. 1 and 2, a window frame B is formed by framing upper and lower frames 1 and 2 and a vertical frame 3 in a rectangular shape within a window frame opening A.
2 and 3 are fixed by screwing to the upper, lower and side structures 10, 11 and 12 of the window frame opening, respectively. On the indoor side of this window frame B, the end of the interior material 13, its base material 14, or the structural material 15 of the frame are exposed, so this part is finished by providing an opening finishing frame C. There is. Such a picture frame C is usually fixed to a window frame opening on its outdoor side and indoor side. That is, on the outdoor side, for example, as shown in the upper frame 1, a locking protrusion 1b is formed on the frame member to protrude toward the indoor side, and this locking protrusion 1b is connected to the outdoor end of the frame _C1 . The connection can be made by inserting it into the insertion groove 16 provided in the frame member, or as shown in the lower frame 2 and vertical frame 3, a heat insulating material 17 can be placed inside the locking edges 2a and 3a formed integrally with the frame member. At the same time, a clip 18 having a curved convex portion 18a is secured at a position substantially opposite to the locking edges 2a, 3a, and a clip 18 is secured between the locking edges 2a, 3a and the curved convex portion 18a of the clip 18. It is attached by holding the outdoor ends of picture frames C ₂ and C ₃ under pressure. However, on the other hand, the indoor end of the picture frame C is free, and there is a gap between the inner surface of the opening and the picture frame C, so the picture frame C has the disadvantage of blurring inward and outward as shown by the arrow. It was hot.

It is an object of the present invention to solve the above-mentioned drawbacks and to propose a fixing device that can easily, quickly and reliably fix a finished picture frame to a window frame opening.

That is, in the present invention, a fixing fitting having a protruding piece with a sharp tip is fixed to the indoor side of a window frame installed in the window frame opening, and the frame is fixed by piercing the protruding piece into the protruding piece. Below, we will explain with drawings an example in which a frame is attached to the side of a window frame opening with the same configuration as that shown above, but it will also be applied to the upper and lower parts of the window frame opening and to windows with other configurations. The description of the frame opening is also similar to that of this example.

First, in FIG. 3, the symbol A is the window frame opening, 3
indicates the vertical frame of the window frame. A locking protrusion 19 is provided protrudingly provided on the inside of the indoor end of the vertical frame 3', and the outer mounting edge 2
0, a receiving groove portion 21 is formed between the two. The mounting edge 20 of the vertical frame 3' is screwed to the side structure 12 of the window frame opening A, and a fixing fitting 5 bent at right angles is fixed to the indoor end of the vertical frame 3'. ing. That is, as shown in FIG. 4, this fixture 5 is made of metal such as stainless steel, and has a long piece 5a and a short piece 5b bent at a substantially right angle, and has a pointed tip at the tip of the long piece 5a. A thrusting protrusion 6a is extended, and a thrusting protrusion 6b, which has the same shape as and parallel to the thrusting protrusion 6a, extends from the end of the short piece 5b. Further, reinforcing ribs 23a and 23b are provided along the right-angled bent portions of the long piece 5a and the short piece 5b and the longitudinal direction of the long piece 5a, respectively.
is formed. A screw insertion hole 24 is provided in the short piece 5b.
a is provided, and the fixing metal fitting 5 is fixed by inserting a screw into the screw insertion hole 24a and fixing it to the receiving groove portion 21 of the vertical frame 3. In addition, the fastening part using screws may be provided on either or both of the long piece 5a or the short piece 5b depending on the engagement of the members between the opening A and the vertical frame 3, and furthermore, the fastening part with screws may be provided on either or both of the long piece 5a or the short piece 5b. It may be attached to. When several fixing fittings 5 are attached to the indoor end of the vertical frame 3 as described above, the protruding pieces 6a and 6b are located at the outer and inner ends of the fixing fitting 5, respectively, and are directed toward the indoor side. stand out.
At this time, it is preferable that the thrusting protrusion 6a protrudes more toward the outside than the side surface of the interior material 13 for the purpose of attaching the finished frame 7, as will be described later.

Next, a finished frame _C'2 for the opening side of the frame C' is attached to the indoor side of the vertical frame 3'. This picture frame _C'2 is made of synthetic resin or wood, and has two surfaces facing outdoors with a distance l' that is approximately the same as the distance l between the protruding pieces 6a and 6b of the fixing bracket 5. In particular, the interior finishing portion C' ₂ a provided along the inner peripheral surface of the window frame opening A and the interior material formed by bending outward from the indoor end of this interior finishing portion C' ₂ a at a substantially right angle. It is preferable to configure it as an L-shaped frame consisting of an interior material wood end finishing portion C' ₂ b for finishing the wood end of 13. When the picture frame C' ₂ is pre-framed into a rectangular shape together with other window frame frames and pushed into the window frame opening A from the indoor side to the outdoor side, the protruding pieces 6a and 6b of the fixing fitting 5 will While facing the indoor side, the finishing part C' _{2 a} of the finished picture frame C' 2 and the finishing part C' ₂ of the interior wood finishing part C' 2
Since the rear surface 31 of b faces the outdoor side with an interval l', the protruding protrusion 6b of the short piece 5b and the protruding protrusion 6a of the long piece 5a of the fixing bracket 5 face the outdoor surfaces 30, 31, respectively. thrust into Therefore, by simply pushing the finished frame C' ₂ toward the outside, it is connected to the vertical frame 3' and securely fixed within the window frame opening A, achieving the finish inside the opening and the finish of the interior material. Ru. Incidentally, piercing holes may be provided in advance on the outdoor surfaces 30, 31 of the finished picture frame _C'2 . In addition, a packing 25 made of synthetic resin or the like is provided in the receiving groove 21 of the vertical frame 3', and since this packing 25 has a heat insulating ability, the picture frame _C'2 is insulated from the vertical frame 3', thereby preventing dew condensation. is prevented. Moreover, the end of the finished portion C' ₂ a inside the opening of the frame C' ₂ is held down by the locking ridge 19 and this packing 25, and is housed on the back side of the locking ridge 19. For this reason, the wood end can be treated in a nice manner, and the interior appearance can be beautifully finished even if the dimensions are not precisely finished. Of course, the fixing fittings 5 and their mounting screws are not exposed indoors at all. More picture frames
Since C' ₂ is fixed to the fixture 5 at its indoor and outdoor ends, it does not shake like a conventional picture frame. Moreover, since reinforcing ribs 23a and 23b are formed on the bent portion and the long piece 5a of the fixing fitting 5, the reinforcing ribs 23a allow the short piece 5b and the long piece 5a to
a is securely held at a predetermined angle, and the reinforcing rib 2
3b has sufficient resistance against the external force applied when pushing in the picture frame C' ₂ and the external pressure applied from the inside after the picture frame is attached, preventing the long piece 5a from bending and holding the insertion protrusion 6a in a predetermined direction. At the same time, the picture frame _C'2 is also firmly held. Furthermore, when renovating a house, the picture frame C′ ₂ can be pulled out and disassembled.

Although the example in which one protruding piece is provided at each of the inner and outer ends of the fixing metal fitting 5 has been described above, the present invention is not limited to this example. For example, as shown in FIG. Two protruding pieces 6b', 6'' and 6a', 6a'' are provided on each of the short piece 5b and the long piece 5a, and these two protruding pieces are not placed on the same plane, but a part of each piece is bent to form an uneven shape. It may be formed into In this case as well, the protruding protrusions 6b' and 6b'' on the short piece 5b side are inserted into the end of the finished part of the opening inside the picture frame, and the protruding protrusions 6a' and 6a'' on the long piece 5a side are used to finish the wood end of the interior material of the frame. Push it into the back of the part.

Next, FIG. 6 shows another embodiment of the present invention, in which the indoor end of the vertical frame 3'' is bent into a substantially right-angled O-shape, and the side structure 1 of the window frame opening is bent.
It is fixed with screws at 2. The fixing metal fitting 5' has a long piece 5a' and a short piece 5b' formed in an L shape like the above-mentioned fixing metal fitting 5, and protruding pieces 6a 1 and 6 a ₁ are inserted at the tip of the long piece 5a' and the end of the short piece 5b', respectively. _Further , reinforcing ribs 23a' and 23b' are provided at the bent portions of the long and short pieces 5a' and 5b' and at the long piece 5a', respectively.
However, the short piece 5b' of this fixture 5 is attached to the vertical frame 3''.
In addition, the long piece 5a' is fixed to the side structure 12 together with the vertical frame. Moreover, in this example, the long piece 5
A long piece 5a' is folded up and formed at the indoor end of the reinforcing rib 23b' formed in the longitudinal direction of a'.
A folded-up portion 27 is provided on an extension of the top of 3b'. The picture frame C' ₂ is thrust and fixed to the thrusting protrusions 6a ₁ and 6a ₂ in the same manner as described above.

With the above structure, the thrusting protrusion 6a ₁ located in front of the folding portion 27 is supported by the reinforcing rib 23b' against the force when pushing the picture frame C' ₂ into the window frame opening. Therefore, the resistance against the pushing force further increases, and since the folded-up portion 27 forms a reinforcing rib substantially perpendicular to the reinforcing rib 23b', the long piece 5a' is resistant to deformation such as twisting. After the picture frame _C'2 is attached, the resistance to external pressure applied from the inside also increases. In addition, as shown in the figure, interior material 1
The end of the wood 3' may protrude inward from the level of the inner surface of the long piece 5a' due to construction errors, but even in such cases, if the folding part 27 is formed on the fixing bracket 5', the protruding part can be folded. Since it is received on the back side of the raised part 27, construction becomes easier. Note that the inner edge of the picture frame C' ₂ protrudes inward than the inner edge of the vertical frame 3'', but in such a case, the vertical frame 3'' can be removed from the indoor side.
Since the connecting part between the frame _C'2 and the picture frame C'2 is not visible, it is sufficient to finish this part by simply connecting it through the gasket 28.
is not necessarily necessary.

As explained in detail above, according to the present invention,
The finished picture frame on the indoor side of the window frame opening is pushed into the window frame opening, and its outdoor side is pushed into each of the protruding pieces of the long and short pieces of the fixing bracket fixed to the indoor side of the window frame. Since it can be twisted and installed firmly,
Work can be done easily and quickly. Further, since the finished picture frame is fixed by the long and short projecting pieces of the fixing metal fitting, no wobbling will occur even if the expected width of the finished picture frame is large.
