However, when the conventional technique as described above is used for the sash frame fixed to the upper frame of the sash, there are the following problems.
Examples of the sash frame fixing member fixed to the upper frame of the sash include an example of a roll curtain device. Such an adherent member needs to be screwed from below the bottom surface of the sash frame, and a plurality of tapping holes are formed along the longitudinal direction on the bottom surface of the sash frame.
For this reason, it is necessary to arrange the back plate as a reinforcing plate so as to avoid the tapping holes, and there are restrictions on the width and the arrangement position of the back plate.
Thus, since the width | variety and arrangement | positioning position of a backplate are restrict | limited, the attachment position of the to-be-attached member which attaches a backplate as a foundation | substrate was also restrict | limited.
On the other hand, a configuration is also conceivable in which a back plate having a width straddling a plurality of tapping holes is arranged above these tapping holes and screwed from below through the tapping holes. However, in this case, the back plate and the bottom surface of the sash frame are separated from each other by the height of the tapping hole. For this reason, there is a problem that the sash frame may be distorted.

  The present invention has been made in view of the above-described problems. When the reinforcing plate is placed on the bottom surface, the width of the reinforcing plate and the restriction on the arrangement position are reduced, and good reinforcement is performed. It aims to provide a sash frame that can be used.

  In order to solve the above problems, the sash frame of the first aspect of the present invention is a sash frame attached to the upper frame of the sash, and a bottom surface portion extended along the upper frame; The upper surface is extended upward from an end portion in a direction orthogonal to the extending direction of the bottom surface portion, the side surface portion is extended along the extending direction of the bottom surface portion, and is provided to protrude upward from the bottom surface portion. A first tapping hole portion extending along an extending direction of the bottom surface portion; a first protrusion portion projecting toward the side surface portion in the first tapping hole portion; and the side surface portion. A second tapping hole portion that protrudes above the bottom surface portion and extends along the extending direction of the bottom surface portion, and the second tapping hole portion has a direction toward the bottom surface portion. A protruding second protrusion, and the first protrusion Between the serial bottom portion, and is inserted into a gap between said bottom portion and the second protruding portion, and configured to include a reinforcing plate which is placed on the upper surface of the bottom portion.

According to the sash frame, since the first tapping hole portion is provided on the bottom surface portion and the second tapping hole portion is provided on the side surface portion, the first tapping hole portion is provided between the first protrusion and the bottom surface portion. And a reinforcement board can be inserted in the clearance gap between the 2nd protrusion part and bottom face part of a 2nd tapping hole part, and a reinforcement board can be mounted in the upper surface of a bottom face part.
Between the first tapping hole portion and the side surface portion, since no other tapping hole portion is provided between them, the first tapping hole portion and the side surface portion are not straddled. Can be used for mounting the reinforcing plate.

In the sash frame, the reinforcing plate is preferably used as a base for screwing the adherend member from below the bottom surface.
In this case, since the wide reinforcing plate that overlaps the bottom surface portion can be used as the base, the adherend member can be firmly fixed.

  According to the sash frame of the present invention, the reinforcing plate can be placed without straddling another tapping hole portion between the first tapping hole portion and the side surface portion on the upper surface of the bottom surface portion. Is placed on the bottom surface, there is an effect that the reinforcement of the width and arrangement position of the reinforcing plate is reduced and good reinforcement can be performed.

The upper frame frame 11 (sash frame) is a frame member that is extended in a substantially constant cross-sectional shape along the extending direction of the upper frame 2. The upper frame frame 11 is a member that covers the upper frame 2 from the side in the room of the building 1 and forms a frame structure that protrudes further indoors than the upper frame 2.
The upper frame picture frame 11 can be formed of an extruded material made of an aluminum alloy, for example.

A heavy object can be attached to the lower surface of the upper frame frame 11 as an adherent member. For example, when a roll curtain is arranged on the indoor side of the panel 5 of the building 1, it is possible to attach a roll curtain device 20 (adhering member) that accommodates the roll curtain from below.
Therefore, a reinforcing plate 14 made of, for example, a metal plate is disposed inside the upper frame frame 11. That is, the reinforcing plate 14 can be used as a base for fixing a heavy object such as the roll curtain device 20.
The shape of the reinforcing plate 14 is not particularly limited as long as the upper frame frame 11 can be reinforced or used as a base. An example of the reinforcing plate 14 shown in FIG. 3 is a flat plate member in which a rectangular section having a constant width is extended in the illustrated depth direction by the same length as the upper frame frame 11.

The upper frame frame 11 includes a bottom surface portion 11A, a locking portion 11B, an indoor side surface portion 11C, and an upper surface portion 11D.
The bottom surface portion 11A, the locking portion 11B, the indoor side surface portion 11C (side surface portion), and the top surface portion 11D are formed over the entire extending direction of the upper frame frame 11, and all of them extend from the upper frame 2. It is extended along the current direction.
Hereinafter, the configuration of the upper frame frame 11 will be described based on the positional relationship in a state of being fixed to the upper frame 2. For this reason, in the case of representing the relative positional relationship in the direction orthogonal to the extending direction of the upper frame 2 in the upper frame frame 11, the direction closer to the upper frame 2 (the left side in FIG. 3) unless otherwise specified. Is called “outside of the room”, and the direction away from the upper frame 2 (the right side in FIG. 3) is called “inside of the room”. That is, “outside” in this case indicates a relative positional relationship in “inside”.

The bottom surface portion 11 </ b> A is a plate-like portion provided on the bottom portion of the upper frame frame 11 in order to form a plane portion aligned with the bottom surface portion 2 c of the upper frame 2 on the indoor side with respect to the upper frame 2.

On the upper surface of the bottom surface portion 11A, a locking portion 11B and a bottom surface tapping hole portion 12 (first tapping hole portion) are formed in this order from the outdoor side toward the indoor side.
An indoor side surface portion 11C extending upward is connected to an end portion on the most indoor side of the bottom surface portion 11A.

The locking part 11B is a shape part for locking the upper frame picture 11 to the second plate-like part 7b of the connecting member 7 fixed to the picture frame connecting part 2b. The projecting part 11c and the holding part 11d With.
The protrusion part 11c is a shape part for contacting the second plate-like part 7b from below. The protrusion part 11c is comprised by the protrusion extended along the extension direction (illustrated depth direction of FIG. 3) of the upper frame frame 11 in the several location which overlaps with a 2nd plate-shaped part.
The holding part 11d is bent so as to cover the tip part of the second plate-like part 7b arranged on each projection part 11c from above with the bottom part 11A and to be sandwiched between the bottom part 11A. It consists of a plate-shaped part.

The bottom tapping hole portion 12 is a convex portion that extends over the entire extending direction of the upper frame frame 11 in order to fix the end portion of the upper frame frame 11 in the extending direction.
The bottom tapping hole portion 12 has a tapping hole 12a formed of a U-shaped groove extending in the extending direction and opened upward.
At the upper end of the bottom tapping hole portion 12 on the indoor side, a holding piece portion 12b (first protrusion) is formed that protrudes in the horizontal direction toward the indoor side surface portion 11C located closer to the indoor side. ing.
A gap into which the reinforcing plate 14 can be inserted is provided between the holding piece portion 12b and the bottom surface portion 11A.
The gap between the holding piece portion 12b and the bottom surface portion 11A and the position of the bottom surface tapping hole portion 12 are determined so that the reinforcing plate 14 can be inserted along the bottom surface portion 11A. For this reason, the holding piece portion 12b is not limited to the upper end portion of the bottom surface tapping hole portion 12, but can be formed at an appropriate position between the bottom surface portion 11A.

The upper surface of the bottom surface portion 11A between the bottom surface tapping hole portion 12 and the indoor side surface portion 11C is a smooth flat surface, and a mounting surface 11a on which the reinforcing plate 14 is mounted is formed.
A screw hole for inserting a screw 18 for screwing the reinforcing plate 14 is formed in the bottom surface portion 11A in the range of the mounting surface 11a.

The indoor side surface portion 11 </ b> C is a plate-like portion that rises upward from the end on the most indoor side of the bottom surface portion 11 </ b> A and extends over the entire extending direction of the upper frame frame 11.
In the indoor side surface portion 11C, a side surface tapping hole portion 13 (second tapping hole portion) protruding above the bottom surface portion 11A is provided on the inner surface facing the outdoor side.

The side surface tapping hole portion 13 is a convex portion that extends over the entire extending direction of the upper frame frame 11 in order to fix the end portion of the upper frame frame 11 in the extending direction.
The side surface tapping hole portion 13 has a tapping hole 13a made of a U-shaped groove extending along the extending direction and opened to the outdoor side. A holding piece 13b (second protrusion) protruding in the vertical direction from the tip on the bottom surface 11A side toward the bottom surface 11A is formed at the tip of the side tapping hole 13 in the protruding direction. Has been.
A gap is formed between the front end portion of the holding piece portion 13b in the protruding direction and the placement surface 11a of the bottom surface portion 11A so that the reinforcing plate 14 can be inserted along the bottom surface portion 11A. For this reason, the holding piece portion 13b is not limited to the tip portion of the bottom surface tapping hole portion 13, and can be formed at an appropriate position between the holding side portion 13b and the indoor side surface portion 11C.

  The upper surface portion 11D is a plate-like portion that extends in the horizontal direction from the upper end portion of the indoor side surface portion 11C toward the outdoor side.

In order to fix the upper frame frame 11 having such a configuration to the building 1, first, the reinforcing plate 14 is placed in the gap formed between the placement surface 11a, the holding piece portion 12b, and the holding piece portion 13b. Then, the reinforcing plate 14 is placed on the placement surface 11a.
At this time, both end portions in the width direction of the reinforcing plate 14 are guided by the side surface of the bottom surface tapping hole portion 12 and the indoor side surface portion 11C, and the upper surface of the reinforcing plate 14 is guided by the holding piece portions 12b and 13b. . For this reason, the reinforcing plate 14 is smoothly inserted in the upper frame frame 11.

  After positioning the reinforcing plate 14 with respect to the mounting surface 11a, the screw 18 is inserted from below through the screw hole formed in the bottom surface portion 11A and screwed into the reinforcing plate 14. Accordingly, the reinforcing plate 14 is fixed to the bottom surface portion 11A in a state where the surface of the reinforcing plate 14 is overlapped with the placement surface 11a.

Next, the presser portion 11d of the locking portion 11B is locked to the tip end portion of the second plate-like portion 7b of the connecting member 7 fixed to the frame connecting portion 2b, and the protrusion portion 11c of the locking portion 11B is connected to the first end portion. 2 is brought into contact with the lower surface of the plate-like portion 7b. At this time, the upper surface portion 11 </ b> D overlaps the upper surface of the angle 15. As a result, the upper frame frame 11 is locked to the connecting member 7 and the angle 15.
In such a locked state, the end portion on the outdoor side of the upper frame frame 11 is positioned along the connecting member 7, and the bottom surface portion 11 </ b> A is aligned with the bottom surface portion 2 c of the upper frame 2.

Next, the screw 19 is inserted into the bottom surface portion 11A from below at the position of the intermediate portion between the adjacent protrusions 11c and facing the second plate-like portion 7b, and the screw 19 is inserted into the second plate-like shape. Screw into part 7b. Thereby, the bottom surface portion 11 </ b> A is fixed to the connecting member 7.
Further, the screw 16 is inserted from above the upper surface portion 11D, and the screw 16 is screwed into the second plate-like portion 7b. Thereby, the upper surface portion 11 </ b> D is fixed to the angle 15.
In this way, the upper frame frame 11 is fixed to the upper frame 2.
The end portion of the upper frame frame 11 is fixed by screwing into a tapping hole 12a, 13a by inserting a screw into an appropriate fixing member connected to the vertical frame 3.

Since the reinforcing plate 14 is screwed onto the bottom surface portion 11 </ b> A, the bottom frame portion 11 </ b> A is reinforced by the reinforcing plate 14.
The reinforcing plate 14 can be used as a base for fixing a heavy object such as the roll curtain device 20, for example.
For example, the roll curtain device 20 is inserted into the mounting hole of the roll curtain device 20 disposed on the bottom surface 11b of the bottom surface portion 11A from below and the screw 21 is screwed into the bottom surface portion 11A and the reinforcing plate 14. Can be fixed.

According to the upper frame frame 11 of the present embodiment, the side surface tapping hole portion 13 is provided so as to protrude from the indoor side surface portion 11C above the bottom surface portion 11A. Thereby, in order to fix the edge part of the upper frame frame 11, the tapping holes 12a and 13a can be provided in two places spaced apart in the horizontal direction.
At that time, since the side surface tapping hole portion 13 protrudes above the bottom surface portion 11A, there is a smooth mounting surface between the bottom surface tapping hole portion 12 and the indoor side surface portion 11C on the upper surface of the bottom surface portion 11A. 11a is formed.
As a result, in the upper frame frame 11, the entire surface between the bottom surface tapping hole portion 12 and the indoor side surface portion 11C without the side surface tapping hole portion 13 getting in the way and without straddling the side surface tapping hole portion 13. The reinforcing plate 14 can be placed over the entire area.
Therefore, in the upper frame frame 11, a wider reinforcing plate 14 is placed as compared with the case where another tapping hole portion is formed between the bottom surface tapping hole portion 12 and the indoor side surface portion 11C. Can do.
Thereby, in the reinforcement board 14 used for the upper frame frame 11, the restrictions of the width | variety and arrangement position for avoiding the side tapping hole part 13 are reduced.
For this reason, according to the upper frame frame 11, when the reinforcement board 14 is used as a foundation | substrate, the restriction | limiting of the attachment position of adherend members, such as the roll curtain apparatus 20, can be reduced.

In the above description of the embodiment, an example in which the reinforcing plate 14 is a flat plate member has been described. However, the cross-sectional shape of the reinforcing plate 14 is not limited to a flat plate.
As the cross-sectional shape of the reinforcing plate 14, an appropriate shape that can be inserted into the gap between the holding piece portions 12b and 13b and the placement surface 11a can be adopted. For example, the thickness of the reinforcing plate 14 may be changed so as to protrude above the holding piece portions 12b and 13b except in a region sandwiched between the holding piece portions 12b and 13b.
Moreover, the clearance gap between holding piece part 12b, 13b and the mounting surface 11a can be suitably changed by changing the position of holding piece part 12b, 13b.
In particular, the distance between the tip of the holding piece 13b and the mounting surface 11a can be adjusted by appropriately setting the position of the side tapping hole 13 or changing the protruding amount of the holding piece 13b. It can be set freely within the range of 11C height.
For this reason, the freedom degree of the magnitude | size of the clearance gap between the front-end | tip part of the holding piece part 13b and the mounting surface 11a is larger than the freedom degree of the magnitude | size of the clearance gap between the holding piece parts 12b and 11a.
For example, you may comprise the reinforcement board 14 by the cross-sectional L-shaped member which consists of a flat plate part in alignment with the mounting surface 11a, and a flat plate part in alignment with the inner surface of the indoor side surface part 11C.
Furthermore, it is not essential that the length of the reinforcing plate 14 be equal to that of the upper frame frame 11. The upper frame frame 11 may be partially reinforced by making it shorter than the upper frame frame 11.

  In the description of the above embodiment, the example in which the reinforcing plate 14 is fixed to the bottom surface portion 11 </ b> A by the screw 18 has been described, but it is not essential to fix the reinforcing plate 14 by the screw 18.

  In the above embodiment, the upper frame frame 11 has been described as an example in which the bottom tapping hole portion 12 and the side surface tapping hole portion 13 are provided. However, the number of tapping hole portions is not limited to two. For example, it is possible to appropriately provide other tapping hole portions between the locking portion 11B and the bottom surface tapping hole portion 12 and between the side surface tapping hole portion 13 and the top surface portion 11D.

  The components described in the above embodiments can be implemented by being appropriately combined or deleted within the scope of the technical idea of the present invention.
