On the other hand, although not shown, the window frame 2B without an angle is, for example, a window frame 2B that is used as a fitting frame such as a casement window and has no angle as shown in FIG.

[Window frame]
The window frame 20 of the first embodiment is arranged on the indoor side of the window frames 2A and 2B. Hereinafter, a specific configuration of the window frame 20 will be described mainly with reference to FIGS.
The window frames 20 arranged on the indoor side of the upper frame 11, the lower frame 12, and the vertical frames 13 and 14 of the window frame 2A are extruded products made of resin having the same cross-sectional shape. However, the extension of the fin 265 of each window frame 20 is adjusted by cutting the fin 265 according to the distance to the wooden frame 110.

The window frame 20 includes a prospective piece 21, an outdoor inner peripheral piece 22, an indoor inner peripheral piece 23, an outdoor outer peripheral piece 24, an indoor outer peripheral piece 25, and a frame main body 26. .
The prospective piece 21 is a plate-like portion provided along the prospective direction of the window frame 2A.

  The outdoor inner peripheral piece 22 extends from the outdoor end of the prospective piece 21 to the inner peripheral side of the window frame 2A in the finding direction (opposite frame material side). Note that the outdoor inner peripheral piece 22 of the present embodiment has a base end 221 that is continuous with the prospective piece 21, an inclined part 222 that extends diagonally outward from the base end 221, and a finding direction from the inclined part 222. And a distal end portion 223 extending to the inner peripheral side. At the tip of the tip 223, a projection 224 projecting toward the indoor side is provided.

The indoor inner peripheral piece 23 extends from the indoor side end of the prospective piece 21 to the inner peripheral side in the finding direction of the window frame 2A. A protrusion 231 protruding toward the outside of the room, that is, toward the protrusion 224 is provided at the tip of the indoor inner peripheral piece 23.
Therefore, the prospective piece 21, the outdoor inner peripheral piece 22, and the indoor inner peripheral piece 23 constitute a groove forming section for partitioning and forming the groove 27 opening on the inner peripheral surface of the window frame 20. The prospective piece 21 is the bottom surface of the groove forming part.

As shown in FIG. 4, a groove 211 that is continuous along the longitudinal direction of the window frame 20 is formed on the surface of the prospective piece 21 on the groove 27 side. As described later, the groove 211 can be used for positioning when the flathead screw 5 or the tapping screw 6 is screwed.
In the window frame 20, the prospective piece 21 is also used as a threaded portion and a locking portion. That is, when the countersunk screw 5 is screwed into the prospective piece 21 from the angle 15, the prospective piece 21 is used as a threaded portion.
Further, when the tapping screw 6 is screwed into the prospective piece 21 and the head of the tapping screw 6 is locked to the prospective piece 21, the prospective piece 21 is used as a locking portion.

The outdoor outer peripheral piece 24 extends from the outdoor end of the prospective piece 21 to the outer side in the finding direction of the window frame 2A, that is, the side opposite to the extending direction of the outdoor inner peripheral piece 22.
The indoor outer peripheral piece 25 extends from the indoor end of the prospective piece 21 to the outer peripheral side in the finding direction of the window frame 2A, that is, to the opposite side to the extending direction of the indoor inner peripheral piece 23. At the tip of the indoor outer peripheral piece 25, a projection 251 protruding toward the outdoor side, that is, toward the outdoor outer peripheral piece 24 is provided.

Here, the finding dimensions from the prospective piece 21 to the distal ends of the outdoor inner peripheral piece 22 and the indoor inner peripheral piece 23 are the same, and the positions of the surfaces of the projections 224 and 231 in the finding direction are aligned.
In addition, the finding dimensions from the prospective piece 21 to the distal end of the outdoor outer peripheral piece 24 and the indoor outer peripheral piece 25 are the same, and the positions of the distal end of the outdoor outer peripheral piece 24 and the surface of the protrusion 251 are aligned. I have.
Further, in the present embodiment, the found dimensions from the prospective piece 21 to the distal ends of the outdoor inner peripheral piece 22 and the indoor inner peripheral piece 23 are the same as those of the prospective piece 21 to the outdoor outer peripheral piece 24 and the indoor outer peripheral piece 25. It is longer than the found dimension up to the tip.
For this reason, the depth (foundation size) of the groove 27 defined by the prospective piece 21, the outdoor inner peripheral piece 22, and the indoor inner peripheral piece 23 is the prospective piece 21, the outdoor outer peripheral piece 24, and the indoor outer peripheral piece. The depth (found size) of the groove 28 defined by the portion 25 is made larger, and in this embodiment, the size ratio is about 2: 1.

  The width dimension of the opening of the groove 27 in the expected direction, that is, the dimension between the protrusions 224 and 231 is made larger than the diameter of the head of the tapping screw 6 described later. It is configured to be screwable into.

The frame main body 26 is provided between an extension 261 extending from the distal end of the indoor outer peripheral piece 25 to the indoor side and a distal end of the indoor inner peripheral piece 23 and the indoor end of the extension 261. And a fin 265 extending from the indoor end of the extension 261 to the outer periphery in the finding direction.
The surface portion 262 is a direction in which the inner surface portion 263 extends from the front end portion of the indoor inner peripheral piece portion 23 toward the interior in the expected direction, and a direction from the indoor side end portion of the inner surface portion 263 to the indoor side end portion of the extension portion 261. And the interior surface portion 264 extending along the line. The inner surface portion 263 and the indoor surface portion 264 are arranged orthogonal to each other. Therefore, in the window frame 20, a hollow portion having a rectangular cross section is formed by the indoor inner peripheral piece 23, the indoor outer peripheral piece 25, the extension 261 and the surface 262 (the inner surface 263 and the indoor surface 264). I have.

In addition, the surface portion 262 of the window frame 20 may be formed of a plate-like member that linearly connects the indoor inner peripheral piece portion 23 and the extension portion 261. In this case, a hollow portion having a right-angled triangular cross section is formed by the indoor inner peripheral piece 23, the indoor outer peripheral piece 25, the extension 261, and the surface 262.
Further, the surface portion 262 of the window frame 20 may be configured by a member curved in an arc shape. In this case, a hollow portion having a fan-shaped cross section is formed by the indoor inner peripheral piece 23, the indoor outer peripheral piece 25, the extension 261, and the surface 262.

The interior surface portion 264 and the fin portion 265 are formed continuously in the finding direction, and the interior surfaces (surfaces) thereof are flush with each other.
Grooves 266 are formed on the outdoor surface of the fin 265 at regular intervals in the finding direction. The groove 266 is formed continuously in the longitudinal direction of the fin portion 265, and is configured so that the fin portion 265 can be cut at the position of each groove 266 to set the extension dimension (found size) of the fin portion 265. Have been.
For example, in FIG. 1, the window frame 20 attached to the lower frame 12 is different from the window frame 20 attached to the upper frame 11 and the window frame 20 attached to the vertical frames 13 and 14 from the angle 15 of the lower frame 12. The extension of the fin 265 is set to be short according to the height up to the wooden frame 110.

[Mounting structure of window frame to window frame with angle]
As shown in FIGS. 1 to 3, the window frame 2 </ b> A of the present embodiment has an angle 15, and the window frame 20 is screwed to the angle 15.
That is, the window frame 20 is arranged on the outer peripheral side of each angle 15 of the window frame 2A (upper frame 11, lower frame 12, vertical frames 13, 14). At this time, a protrusion 151 is formed on the outer peripheral surface of the indoor side end of the angle 15, and the surface of the protrusion 231 of the window frame 20 is in contact with the protrusion 151.
The outdoor surface of the distal end portion 223 of the outdoor inner peripheral piece 22 of the window frame 20 is in contact with the indoor surface of the window frame 2A.
A plurality of countersunk holes 152 are formed in the angle 15 along the longitudinal direction of the angle 15, and countersunk screws 5 are inserted into each of the countersunk holes 152. Each flathead screw 5 is screwed into a prospective piece 21 of the window frame 20. At this time, the countersunk screw 5 can be smoothly screwed into an appropriate position by screwing the tip of the countersunk screw 5 into the groove 211 of the prospective piece 21. Thereby, the window frame 20 is fixed to the outer peripheral side of the angle 15.

  In this embodiment, the window frame 20 attached to the upper frame 11 and the lower frame 12 is disposed between the upper and lower ends of the window frame 20 attached to the vertical frames 13 and 14. In order to cover a connection portion of each window frame 20, a frame connection cover 30 shown in FIG. 4 is attached.

[Mounting structure of window frame to window frame without angle]
Next, a state in which the window frame 20 is attached to the window frame 2B having no angle will be described with reference to FIG. Since the mounting structure of the window frame 20 to the upper frame, the lower frame, and the left and right vertical frames of the window frame 2B is basically the same, in FIG. 5, the mounting structure to one vertical frame 14B will be described in an enlarged manner. .

  A fin 16 is formed on each frame of the window frame 2B, and the window frame 20 is arranged on the inner peripheral side of the fin 16 of the window frame 2B. Then, the tapping screw 6 is inserted into the groove 27 of the window frame 20, and the tapping screw 6 is screwed into the prospective piece 21 with its tip aligned with the groove 211 of the prospective piece 21. Further, the tapping screw 6 is screwed into a fin 16 which is a portion to be attached to the window frame 2B. For this reason, the head of the tapping screw 6 is locked to the prospective piece 21 which is a locking portion.

  A cover member 60 is attached to the groove 27 as shown in FIGS. The cover member 60 includes a covering portion 61 that closes the opening of the groove 27, two legs 62 extending from the outdoor side edge and the indoor side edge of the covering portion 61 toward the prospective piece 21 side, respectively. Thereby, it is formed in a substantially U-shaped cross section. The cover member 60 is a long member along the longitudinal direction of each window frame 20, and covers the entire length of the groove 27 exposed on the inner peripheral surface of the window frame 20.

A step is formed at a corner of the cover member 60 where the covering portion 61 and each leg portion 62 are connected, and the covering portion 61 and each leg portion 62 are connected to be elastically deformable. The two legs 62 are inclined in a direction approaching each other as the distance from the covering portion 61 is increased, and further, they are bent to opposite sides in the middle of the extending direction, and the distal ends of the legs 62 are inclined in a direction away from each other. Have been.
The dimension between the distal ends of the legs 62 is smaller than the opening width dimension of the groove 27 (the dimension between the projection 224 and the projection 231).

When each of the legs 62 of the cover member 60 is inserted into the opening of the groove 27 and the cover member 60 is pushed in, each of the legs 62 contacts the projections 224 and 231 from the bent portion to the covering portion 61. Touch For this reason, each leg 62 is bent in a direction approaching each other. When each of the legs 62 enters the groove 27 beyond the protrusions 224 and 231, the tip of each of the legs 62 comes into contact with the prospective piece 21 and returns in a direction away from each other, and the stepped portion becomes the protrusion 224, 231. Even when the cover member 60 is further pushed into the groove 27, the pushing of the cover member 60 toward the prospective piece 21 is restricted because the legs 62 are in contact with the prospective piece 21.
The covering portion 61 of the cover member 60 is disposed on the same plane as the protrusions 224 and 231 and the inner surface 263. Therefore, the cover member 60 is arranged without a step with respect to the window frame 20.

  Also in the window frame 20 attached to the window frame 2B, the fin portion 265 is cut by a length corresponding to the dimension up to the frame-side member such as the wooden frame 110 or the like.

[Effects of First Embodiment]
In the window frame 20 as described above, the countersunk screw 5 inserted into the countersunk hole 152 of the angle 15 is screwed into the prospective piece 21 which is a threaded portion, for the window frame 2A provided with the angle 15. Can be fixed. Further, the window frame 20 can be fixed to the window frame 2B having no angle by screwing the tapping screw 6 from the prospective piece 21 which is a locking portion to the fin 16 of the window frame 2B.
That is, since the window frames 20 having the same cross-sectional shape can be used as each window frame of the window frame 2A with an angle and the window frame 2B without an angle, different window frames are prepared for each of the window frames 2A and 2B. As compared with the above, the type of the window frame 20 can be reduced to one type, and the manufacturing cost and the management cost of the parts can be reduced.

When the window frame 20 is attached to the window frame 2A, the opening of the groove 27 can be covered with the angle 15, so that the design of the window frame 20 can be prevented from deteriorating.
When the window frame 20 is attached to the window frame 2B, the cover member 60 can be attached to the groove 27 to cover the window frame 2B, so that the design of the window frame 20 can be prevented from deteriorating. Further, since the covering portion 61 of the cover member 60 can be arranged on the same plane as the inner surface portion 263 of the window frame 20, the unevenness is not formed on the inner peripheral surface of the window frame 20, and the design is also improved in this respect. Can be improved.

  Since the distal end portion 223 of the outdoor inner peripheral piece portion 22 of the window frame 20 is disposed more outdoor than the outdoor outer peripheral piece portion 24, when the distal end portion 223 comes into contact with the window frame 2A, the outdoor outer peripheral piece portion is provided. 24 can be arranged away from the window frame 2A. Therefore, it is possible to prevent the mounting bracket 130 from interfering with the window frame 20.

The opening width dimension of the groove 27 of the window frame 20, that is, the dimension along the expected direction between the projection 224 and the projection 231 is smaller than the expected dimension of the angle 15, so that the projection from the tip 223 of the window frame 20 to the projection. The dimension up to 231 can be made smaller than the expected dimension of the angle 15.
For this reason, the angle 15 can be reliably bridged between the protrusion 224 and the protrusion 231 of the window frame 20, the opening of the groove 27 can be reliably covered with the angle 15, and the countersunk screw 5 is expected from the angle 15. When screwed into the piece 21, the angle 15 and the window frame 20 can be fixed stably and reliably.

  Since the screw direction of the countersunk screw 5 and the tapping screw 6 into the window frame 20 is the same between the case where the window frame 20 is attached to the window frame 2A and the case where the window frame 20 is attached to the window frame 2B, the window frame 20 uses the window frame 2A and the window frame 2B. Mounting can be performed by almost the same work, and mounting workability can be improved.

Since the frame main body 26 is provided separately from the prospective piece 21, the shape and the like of the surface portion 262 of the frame main body 26 can be freely set, and the appearance design of the window frame can be improved.
The fin 265 of the frame main body 26 can be easily cut at the groove 266, and the extension of the fin 265 can be adjusted according to the gap between the extension 261 and the building frame. The mounting bracket 130 to which the 2B is fixed, the spacer member 120, and the like can be covered with the fin portion 265, and the design can be improved.

[Second embodiment]
Next, the window frame 40 of the second embodiment will be described with reference to FIGS.
The window frame 40 according to the second embodiment has a different structure from the window frame 20. However, similarly to the window frame 20, the window frame 40 serves as a window frame of a window frame 2A with an angle 15 and a window frame of a window frame 2B without an angle. It is also used.

The window frame 40 includes a finding piece 41, an outer outer piece 42, an inner outer piece 43, an outer inner piece 44, an inner inner piece 45, and a fin 465.
The finding piece portion 41 is a plate-like portion formed along the finding direction of the window frame 2A, and functions as a locking portion. On the indoor side surface of the finding piece 41, a groove 411 which is continuous along its longitudinal direction is formed.

  The outer peripheral chamber outer piece 42 extends from the outer peripheral end of the finding piece 41 to the outside of the window frame 2A in the expected direction. The front end (outdoor end) of the outer peripheral chamber outer piece 42 is formed with an inclined surface so as not to interfere with the mounting bracket 130.

  The inner peripheral chamber outer piece 43 extends from the inner peripheral end of the finding piece 41 to the outside of the window frame 2A in the expected direction. At the tip of the inner peripheral chamber outer piece 43, a protruding portion 431 is provided which protrudes toward the outer peripheral side, that is, toward the distal end of the outer peripheral chamber outer piece 42. The inner peripheral chamber outer piece 43 is used as a threaded portion because a flat head screw 5 described later is screwed into the inner peripheral chamber outer piece 43.

  The outer peripheral chamber piece 44 extends from the outer peripheral end of the finding piece 41 toward the interior of the window frame 2A in the expected direction. A protrusion 441 protruding inward is formed at the indoor side end of the outer peripheral indoor piece 44. Further, in the outer-chamber interior piece 44, a projection 442 projecting inward is formed between the projection 441 and the finding piece 41.

  The inner peripheral room piece 45 extends from the inner peripheral end of the finding piece 41 toward the interior of the window frame 2A in the expected direction. A protrusion 451 protruding toward the outer periphery, that is, toward the protrusion 441 is formed at the indoor side end of the inner peripheral indoor piece 45. Further, a projection 452 protruding toward the outer periphery, that is, toward the projection 442 is formed between the projection 451 and the finding piece 41 in the inner peripheral indoor piece 45.

A groove forming portion that defines a groove 47 that is opened on the indoor surface of the window frame 40 is configured by the finding piece portion 41, the outer peripheral indoor piece portion 44, and the inner peripheral indoor piece portion 45, and the finding piece portion 41 is a bottom surface of the groove forming portion. Becomes
The projection 441 and the projection 451 are formed so as to face each other and approach each other, and the projection 442 and the projection 452 are also formed so as to face each other and approach each other. The protrusion dimensions of the protrusion 442 and the protrusion 452 are set to be larger than the protrusion dimensions of the protrusion 441 and the protrusion 451.
The width of the opening of the groove 47 in the finding direction, that is, the dimension between the protrusions 441 and 451, is larger than the width of the middle part of the groove 47 in the finding direction, that is, the dimension between the protrusions 442 and 452. I have. The dimension between the protrusions 442 and 452 is made larger than the diameter of the head of the tapping screw 6 described later, and when the tapping screw 6 is screwed into the finding piece 41, the head of the tapping screw 6 is found. It is configured so that it can be screwed up to the portion 41.

The fin portion 465 extends outward from the distal end portion of the outer peripheral indoor piece portion 44, and the frame main body of the window frame 40 is constituted by the fin portion 465. Therefore, the protrusion 451 and the fin 465 are formed continuously in the finding direction, and the indoor surfaces (surfaces) of the protrusions 441, 451 and the fin 465 are flush with each other.
As in the case of the fin 265, grooves 466 formed at regular intervals in the finding direction are formed on the outdoor surface of the fin 465. The groove 466 is formed continuously in the longitudinal direction of the fin portion 465, and is configured so that the fin portion 465 can be cut at the position of each groove 466 to set the protrusion size (found size) of the fin portion 465. ing.

It is arranged on the outer peripheral side. At this time, a protrusion 151 is formed on the outer peripheral surface of the indoor side end of the angle 15, and the surface of the inner peripheral chamber outer piece 43 of the window frame 40 abuts.
The exterior surface of the projection 431 of the inner peripheral outer piece 43 of the window frame 40 is in contact with the interior surface of the window frame 2A.
A plurality of countersunk holes 152 are formed in the angle 15 along the longitudinal direction of the angle 15, and countersunk screws 5 are inserted into each of the countersunk holes 152. Each countersunk screw 5 is screwed into the inner peripheral chamber outer piece 43 of the window frame 40. Thereby, the window frame 40 is fixed to the outer peripheral side of the angle 15. When the length of the countersunk screw 5 is large, the tip of the countersunk screw 5 may be screwed into the outer peripheral chamber outer piece 42.
