Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a lower frame member for a sash shutter or storm door attached to the outdoor side of a shoji frame provided on a building frame.

(Prior Art) As shown in Figure 4 of the drawings, a lower frame member 30 of a sash shutter (or rain door) is attached to the outdoor side of a lower frame 3 of a shoji frame conventionally provided on a building frame.
is a mounting edge 31 that is fixed to the building frame 10 by overlapping the hanging edge provided on the outdoor side of the lower frame 3 of the shoji frame.
and a rim 32 of the shutter 20 (or shutter) extending from this mounting rim 31 to the outdoor side, and the rim 32 of the shutter 20 (or shutter).
When this is installed on the outdoor side of the shoji frame lower frame 3, it is fixed to the building frame 10 together with the lower frame 3, so that It takes a lot of effort to install it, and it is stuck on the mounting edge 3 on the indoor side.
Since it is fixed only to the bottom frame 1, when an impact load is applied to the mounting edge 32 during installation, such as a shutter (or storm door), the attachment of the mounting edge 31 tends to loosen, and a gap is created between it and the bottom frame 3. Rainwater can enter through the gaps, causing wood-rotting fungi to enter the building frame.
In some cases, this caused growth or reproduction, leading to the deterioration of buildings in a short period of time.

(Purpose of the invention) The present invention solves the above-mentioned drawbacks and provides a sash shutter that can be easily attached to the bottom frame of a shoji frame installed in a building frame, is resistant to impact loads, and has good rain protection. Or, the purpose is to provide a lower frame member for a storm door.

(Technical means for achieving the objective) In order to achieve the above objective, the sash shutter or shutter according to the present invention is a sash shutter or shutter that is attached to the outdoor side of the lower frame of the shoji frame provided on the building frame. or a lower frame member of the shutter, forming a locking edge on the inside of the upper room that locks to the lower frame of the shoji frame;
A retaining edge for supporting a shutter for a sash or a storm door is formed on the outdoor side of the locking edge, and a mounting edge extending downward is integrally formed on the lower surface of the retaining edge, and a mounting edge extending downward from the middle part of the attachment edge is formed on the outdoor side. While forming a draining edge, the lower part of the mounting edge is in contact with and fixed to the building frame, and the lower part of the mounting edge is attached to the building frame below the fixing part of the lower frame of the shoji frame to the building frame. At the same time, the locking edge is locked to the lower frame of the shoji frame above the locking part, and the locking edge is provided at the lower part of the mounting edge and on the lower part of the mounting edge by the draining edge. It is characterized by covering the upper part of the exterior material of the building frame.

(Embodiments) Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Reference numeral 2 in the figure is a lower frame member, and this lower frame member 2
is attached to the outdoor side of the lower frame 3 of the shoji frame provided on the building frame 10, and a locking edge 1 that locks to the lower frame 3 of the shoji frame is formed inside the upper room of the lower frame member 2. A retaining edge 19 is formed on the outdoor side of the locking edge 1 to support a shutter for a sash or a shutter.

The lower frame 3 of the shoji frame supports fittings 27 and 28, and has a hooked edge 7 that engages with the engagement edge 1 at its outdoor end. In this way, the lower frame 3 may have the same configuration as the lower frame of a general shoji frame, but it requires the above-mentioned hook edge 7, locking groove, etc. for locking to the locking edge 1 of the lower frame member 2. shall be.

A hooked edge portion 4 is formed on the indoor side of the receiving edge 19, and a rail 25 for a screen door 26 is formed on the hooked edge portion 4. Alternatively, a groove 5 may be formed on the indoor side surface of the locking edge 1, and an airtight material 6 may be attached to this (see FIG. 6).

Next, the retaining edge 19 is provided at an angle to improve drainage, and the end part has a downward hanging edge 2.
1 is provided. Further, as shown in FIG. 7, this rim 19 may be formed into a substantially T-shaped cross section to support the shutter 22. In this case, a drain hole 23 is formed in the rim 19. establish.

A mounting edge 8 extending downward from the lower surface of the receiving edge 19 is integrally formed. At the top of this mounting edge 8, there is a connecting edge 11 extending diagonally downward toward the indoor side.
and a hanging edge 12 hanging below it, a draining edge 9 protruding toward the outdoor side is integrally formed in the middle part of the mounting edge 8, and a draining edge 9 protruding toward the indoor side is further formed at the lower part of the mounting edge 8. A facing oblique edge 13 and an abutment support edge 14 that abut against the building frame 10 are formed. Note that the beveled edge portion 13 is inclined in order to enable the fastening screw 15 to be screwed in diagonally.

Reference numeral 16 denotes an insertion edge of an airtight material 17 provided upward from the intersection of the connecting edge 11 and the hanging edge 12, and a dovetail groove 18 is provided on the surface facing indoors, and the lower frame of the shoji frame is attached to this edge. The airtight material 17 is inserted into pressure contact with 3.

Reference numeral 24 denotes a drainage hole formed in the connecting edge 11, through which rainwater that enters from the longitudinal end or the connecting portion with the locking edge 1 during use is drained to the outside.

The lower frame member 2 has the locking edge 1 attached to the building frame 1 in advance.
The hook edge 7 formed above the attachment part 7a to the building frame in the lower frame 3 of the shoji frame fitted to the frame 0
The end of the abutting support edge 14 provided below the locking edge 1 is applied to the outdoor side of the building frame 10 below the fastening portion 7a to temporarily fasten it, and then the mounting edge 8 The fastening screws 15 are passed through the beveled edge 13 of the shoji frame, and this is screwed into the building frame 10 and fixed, and the upper part of the exterior material 29 of the building frame 10 is covered with the draining edge 9. Bottom frame 3
It is attached to the outdoor side of the building. When in use, the shutter 20 or the shutter 22 can be supported by the rim 19 of the lower frame member 2.

In addition, in the above-mentioned installed state, as shown in FIGS. 2 and 5 to 7 of the drawings, the parts connecting to or abutting the shoji frame 3, that is, the locking edge 1 and the insertion edge 16 of the airtight material 17, are When the airtight materials 6 and 17 are inserted and tightly connected and abutted, watertightness can be greatly improved, and when a drainage hole 24 is provided in the connecting edge 11 of the mounting edge 8, As shown by the arrow in FIG. 5, rainwater that has entered through the connecting portion of the locking edge 1 passes through the drain hole 24 and reaches the draining edge 9, where it is guided and drained outdoors. 10 and the exterior material 29, this embodiment has the advantage of extremely good rain protection.

(Operations and Effects of the Invention) As mentioned above, the lower frame member for the sash shutter or shutter according to the present invention has a locking edge and an attachment point above and below the attachment part of the shoji lower frame provided on the building frame, respectively. Because it is attached to the edge and is not processed or attached to the above-mentioned fastening part,
Installation work can be done easily. Further, since the lower frame member itself is provided with the mounting edge, and the receiving edge, the locking edge, the draining edge, and the attachment edge are integrally formed, it is strong against impact loads. Furthermore, since the draining edge covers the lower part of the attachment edge and the upper part of the exterior material provided over the lower part of the attachment edge, not only the exterior appearance is good, but also the rain protection is good.
