Accordingly, the sash frame 3 is uniformalized so as to facilitate the manufacture and management thereof. Further, since the sash frame 3 is carried on the bracket 4 so as to be supported thereby, the positioning thereof is facilitated, thereby it is possible to enhance the workability thereof.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retrofitted sash unit which is retrofitted to the outside of an existing sash regardless of its installed state.

[0002]

2. Description of the Related Art When a retrofit sash is installed on the outside of an existing sash for the purpose of soundproofing or heat insulation, the existing sash can be installed in three ways: internal, semi-external and external. Since the protruding widths of the sash frames from the outer wall are different, it is necessary to prepare a sash frame with an expected width according to the protruding width of each sash frame for each installation condition in order to correspond to all existing sashes. Therefore, the number of types of frame materials has increased, and their production and management have become complicated.

Further, the sash frame of the retrofitted sash straddles the existing sash and is directly fixed to the outer wall, but since the outer wall has no clue for positioning the retrofitted sash,
It takes time to position the sash frame on the outer wall, and its mounting workability is poor.

The present invention has been made by paying attention to problems in manufacturing and construction when a sash frame is retrofitted to an existing sash. One type of sash frame can cope with each installation state, and mounting work can be performed. The purpose is to propose a retrofitted sash unit with good performance.

[0005]

[Means for Solving the Problems] Of the three existing sashes, the external sash frame projects the most from the outer wall, increasing the distance between the rear sash and the outer wall.
In the present invention, a waste frame having a prospective width corresponding to the projecting width from the outer wall is used for the existing external sash, and the sash frame of the retrofit sash is connected to this discard frame, thereby The sash frame is also compatible with semi-external sashes with a protruding width smaller than the external sash frame and internal existing sashes, and the sash frame of the post-installed sash is unified with respect to three types of existing sashes, and its production and management To simplify.

Further, by fixing the bracket on which the lower frame of the sash frame of the post-installed sash rests to the outer wall of the lower frame of the lower frame of the discarding frame, the positioning of the sash frame with respect to the outer wall is facilitated and the workability is enhanced.

The waste frame has a prospective width corresponding to the projecting width from the outer wall of the existing external sash, is fixed to the outer wall around the outer periphery of the sash frame of the existing sash, and when the existing sash is external, Fill the space between the sash frame and the outer wall of the retrofit sash.

The sash frame of the post-installed sash has a size that surrounds the sash frame of the existing sash, including the case of internal installation and semi-external installation, and is connected to the discard frame when the existing sash is externally installed.

Since the discard frame has a prospective width corresponding to the protruding width from the outer wall of the existing external sash and fills the space between the outer wall around the existing external sash and the sash frame of the additional sash, Since the sash frame is directly fixed to the outer wall without interposing a waste frame, the sash frame can be adapted to an existing internal sash or semi-external sash with a small protrusion from the outer wall without increasing the width of protrusion from the outer wall.

Further, the sash frame of the retrofitted sash is placed on a bracket arranged below the discard frame, and the sash frame is supported by the sash frame and connected to the discard frame, whereby the positioning of the sash frame is simplified, and its mounting Workability is enhanced. The sash frame of the retrofitted sash is directly fixed to the outer wall.Even when the existing sash is semi-externally or internally attached, the sash frame is placed on the bracket and positioned with respect to the external wall. Workability is secured.

When the existing sash 5 is externally attached, the discarding frame 2 is sandwiched between the outer wall 7 and the sash frame 3 to adjust the distance between the two, so that when the sash 5 is absent, the sash frame 3 is semi-externally attached. It also corresponds to the attached sash frame 6.

As shown in the drawing, the sash frame 3 has a size that surrounds the periphery of the existing sash 5 in correspondence with the width and height dimensions of the discard frame 2, and the end portion on the indoor side is housed inside the indoor space. It has an expected width such that it extends beyond the shoji screen 10 toward the interior. Since the sash frame 3 has a prospective width of a size that projects from the indoor shoji 10 to the indoor side, the sash frame 3 also corresponds to the semi-external and internal sash frames 6. The protruding length of the sash frame 3 from the indoor shoji 10 is as described above.
In the case of the semi-external mounting shown in FIG. 3, the sash frame has a size such that a space is maintained between the outdoor screen 11 inside the sash frame 6 and the indoor screen 10 inside the sash frame 3. The sum of the projecting length of the shoji 3 from the shoji 10 and the estimated width of the discard frame 2 is larger than the protruding width of the external sash frame 6 from the outer wall 7. In the sash frame 3, the upper frame 3 ₁ and the lower frame 3 ₂ and the vertical frames 3 ₃ and 3 ₃ are abutted on the outdoor side of the upper frame 2 ₁ and the lower frame 2 ₂ and the vertical frames 2 ₃ and 2 ₃ of the discard frame 2, respectively. , Screws 12 to each other except between lower frames 2 ₂ and 3 _2.
