2. Description of the Related Art In a sash of an old building, in addition to dirt and damage of the sash, the movement of the sash window becomes poor due to a malfunction of a door car, etc., and furthermore, to a recent high-performance sash such as double glass, air tight. Sash windows are being replaced. However, there are innumerable types of sash structures for residential sliding doors that vary in shape and size depending on the manufacturer and age.
Since it is extremely difficult to procure a new sash window that fits the existing sash frame, it is rarely possible to replace the sash window alone with the sash frame remaining.

Therefore, when replacing the sash window,
How to remove the existing sash outer frame buried in the wall and install a new sash outer frame and sash window, or a pair of new sash outer frame and sash which is slightly smaller inside the sash outer frame while leaving the sash outer frame It was constructed by attaching windows.

[0004]

However, in the above-mentioned conventional method of replacing a sash window, in the method of removing a sash outer frame buried in a wall, the sash outer frame is used as a common part in an apartment house. If it is determined that it belongs, it will be difficult for the individual to replace the sash outer frame of the common part without permission, and even if it is approved, it will require various craftsmen such as plasterers for construction work to break the wall. The interior and exterior of the room had to be occupied for a long period of time, and if it was on the second floor or higher, more scaffolding was required, which had to be costly.

In the method of attaching a pair of sash outer frames and a sash window inside the sash outer frame while leaving the sash outer frame inside, the size of the window opening becomes slightly smaller, so that the feeling of upgrading is impaired. Also, in the case of a terrace door installed at the same height as the floor surface, it is necessary to stand up from the floor surface of the sash lower frame, and there is a possibility that the door may stumble.

Further, when the sash outer frame is left and a new sash window is to be mounted inside the sash window, as shown in FIG. 8, the joining portion 21 of the outer window frame 20 and the joining portion of the inner window frame 22 of the sash window. Appropriate point where 23 meshes is 1
The sash window that can be attached to the sash outer frame of a specific rail pitch is only one place, the dimensions of the mating part are uniquely determined, and the mating part is smaller than this even if the rail pitch is narrower or wider. It cannot be engaged. Therefore, in order to make the sash window compatible with all existing rail pitches (approximately 26 mm to 40 mm), it is necessary to prepare a large number of sash windows having a combined structure, but this is not possible in terms of cost. Met.

Therefore, in the present invention, by utilizing the existing sash outer frame as it is, without changing the opening size of the window and without occupying the inside and outside of the room for a long period of time for the work to break the wall. Another object of the present invention is to provide a method of replacing a sash window that can replace a sash window without requiring a great deal of cost.

[0008]

In order to achieve the above-mentioned object, a method for replacing a sash window according to the present invention comprises a sash outer frame engaged with an opening of a building and a sash sliding in the sash outer frame. In the sash structure of a sliding door comprising a window, when the sash window is closed, at least one of the mating portions having an L-shaped cross section where the inner window frame and the outer window frame mesh with each other is movably fixed in the depth direction of the window. Is what you do.

In addition, the fin rubber for maintaining airtightness, which is provided between the mating portions of the inner window frame and the outer window frame, is changed to a length corresponding to the distance between the mating portions, and the inner window is formed. At least one of a pair of lock members between the frame and the outer window frame is fixed movably in the depth direction of the window.

Alternatively, in a sash structure of a sliding door comprising a sash outer frame engaged with an opening of a building and a sash window slidably moving in the sash outer frame, the sash window in the upper frame of the sash outer frame slides. An upper rail that engages with a notch of the upper frame of the sash window is provided vertically on the upper extension line of the sash window so as to be attachable in accordance with the pitch of the rail.

[0011] The upper rail suspended from the upper frame of the sash outer frame has a diameter larger than the height of the rail already provided on the upper frame of the sash outer frame, and is arranged side by side with the rail to increase the rail height. It is characterized by making it.

Alternatively, in a sash structure of a sliding door comprising a sash outer frame engaged with an opening of a building and a sash window slidingly moved in the sash outer frame, two rails of the sash outer frame have thicknesses of the rails. In addition to covering the covering rail member having an inverted U-shaped cross section having a wider gap, the filling member to be interposed in the gap between the covering rail member and the rail to be covered with the covering rail member is selectively set to two positions. The pitch of the covering rail member is changed.

[0013]

1 to 3 show a first embodiment of a method for replacing a sash window according to the present invention, wherein 1 is an inner window frame of a sash window, and 2 is an outer window frame of a sash window. Reference numeral 3 denotes a joining portion having an L-shaped cross section in the inner window frame 1. Reference numeral 3 denotes this joining portion.
A mating portion 5 having an L-shaped cross section in the outer window frame 2 that meshes with the fin rubber 5 is disposed between the mating portions of the inner window frame 1 and the outer window frame 2 to maintain airtightness. In the drawings, although the glass is omitted, the sash windows are all closed, and when the sash windows are opened, the inner window frame 1 moves upward in FIG. 1 and the outer window frame 2 moves downward in FIG. Things that move.

The joining section 3 of the inner window frame 1 of the sash window includes:
Like the conventional sash window, it is formed integrally with the inner window frame 1, but the joining portion 4 of the outer window frame 2 of the sash window is an angle material having a L-shaped cross section separate from the outer window frame 2. And is fixed to the outer window frame 2 movably in the depth direction of the window with screws 6 and the like that pass through the elongated holes 2 a formed in the outer window frame 2. Of course, the use of the long hole and the screw is only one means, and it may be fixed movably using other means. Alternatively, the joining portion 4 of the outer window frame 2 may be fixed and the inner window may be fixed. The joining part 3 of the frame 1 may be movable.

In the first embodiment of the method for replacing a sash window of the present invention having the above-described structure, an old sash window is first removed, and then the inner diameter of the existing sash outer frame is reduced.
Various data such as frame prospect, rail width, rail shape, door wheel shape, door stop shape and the like are measured, and a pair of inner window frame 1 and outer window frame 2 is created based on the measured data. When the inner window frame 1 and the outer window frame 2 are fitted into the existing sash outer frame, the joining portion 2 of the inner window frame 1 engaged with the existing sash outer frame regardless of the rail pitch is narrow or wide. The mating portion 4 of the outer window frame 2 cannot mesh with the mating portion 4 of the inner window frame 1 in the present invention. Can be moved to a position. And
A fin rubber 4 having a width suitable for the gap between the joined portions of the inner window frame 1 and the outer window frame 2 is disposed in the engagement groove 1a of the inner window frame 1, thereby maintaining airtightness. .

FIGS. 4 and 5 show a second embodiment of the sash window replacement method according to the present invention. In the drawings, reference numeral 7 denotes an upper frame of an existing sash outer frame. There is no rail with which the concave notch 8a formed on the upper frame 8 (the inner window frame or the outer window frame) is to be engaged, and the upper frame 7 has three rails to guide both sides of the upper frame 8 of the sash window. This is a type in which two hanging walls 9 are installed.
In the case of a sash outer frame of this type, if a new sash window having a different upper frame shape from the removed old sash window is incorporated, or if the pitch of the lower rail is changed (described later), the conventional case is supported. I couldn't do that. In this embodiment, a new upper rail 10 made of an angle material having an L-shaped cross section is screwed between the vertical walls 9 of the upper frame 7 which is on an upper extension line of the lower rail (not shown) of the sash outer frame, It is fixed by means such as bonding. A fin rubber 11 is provided on the new upper rail 10 to maintain airtightness between the new upper rail 10 and the recess 8a of the upper frame 8 of the sash window.

FIG. 4 shows a state in which the upper frame 7 of the sash outer frame is horizontal, whereas FIG. 5 shows a method of mounting a new upper rail 10 in a state where the upper frame 7 is inclined. When the new upper rail 10 is mounted on the inclined upper frame 7, the new upper rail 10 is obliquely inserted into the recessed portion 8a of the upper frame 8 of the sash window, and a suitable engagement cannot be obtained. Therefore, the new upper rail 10 is vertically arranged with an appropriate spacer 12 interposed between the upper frame 7 and the new upper rail 10. When this method is applied, even if the upper frame 7 of the sash outer frame is bent up and down in the frontage direction, that is, even if the upper frame 7 is bowed downward or upward, the spacer 12 is appropriately arranged in a relatively concave portion. The new upper rail 10 can be arranged horizontally in the frontage direction.

FIG. 6 shows an application example of the second embodiment of the method for replacing a sash window according to the present invention described above, in which the height of an existing upper rail 7a which has been vertically suspended on the upper frame 7 of the sash outer frame has been described. In this case, the height (projection dimension) is small. If the height of the existing upper rail 7a is small, it is difficult to attach and remove the sash window. Therefore, the new upper rail 10 is installed side by side with the existing upper rail 7a and the new upper rail 7 is higher than the existing upper rail 7a. An appropriate spacer plate 13 is provided by means of bonding, welding, or the like to eliminate a step between the upper rail 10 and the new upper rail 10. By making the rail height appropriate in this way, not only can the mounting and dismounting of the sash window be performed reliably and easily, but also the sliding movement of the sash window can be performed smoothly.

FIG. 7 shows a third embodiment of the method of replacing a sash window according to the present invention. In FIG.
5 is a lower rail previously provided on the lower frame 14, 16
Has a gap wider than the thickness of the lower rail 15 and has a lower rail 1
5, an inverted U-shaped covering rail member for covering 5,
Is a padding member such as a putty or a rod-like body interposed in a gap between the inside of the covering rail member 16 and the lower rail 15. The rail pitch can be changed by arranging the filling member 17 on either side of the lower rail 15 in FIG. In the present embodiment, the rail pitch is enlarged as compared with the conventional case. Align the width diameter type of the coated rail member,
By changing the arrangement of the padding members, the two covered rail members 16 can correspond to various kinds of rail pitches. This covering rail member 16 is not only a lower rail,
It can be applied to the upper rail, and even in the fixing means of the covering rail member 16 to the lower rail 15, the filling member 17 itself may be used as an adhesive, or other bonding means, welding means, or the like may be used. Things.

In each of the above embodiments, when the rail pitch of the sash window is changed, a lock member (not shown) called a crescent between the inner window frame and the outer window frame.
Can be too far away or too close, but this can be dealt with, for example, by making one of the lock members movable in the depth direction of the window.

[0021]

As described above in detail, according to the sash window replacement method of the present invention, when the sash window is closed, at least one of the L-shaped cross sections where the inner window frame and the outer window frame are engaged. Even if the rail pitch of the existing sash outer frame is narrow or too wide, the joining portion of the inner window frame and the joining portion of the outer window frame can be reliably and suitably fixed by being movably fixed in the depth direction of the window. It becomes possible to engage. As a result, the new sash window can be surely adapted to the existing sash outer frame having various rail pitches only by moving and adjusting the joining portion of the sash window of the present invention.

Alternatively, an upper rail which engages with a notch of the upper frame of the sash window on the upper extension of the rail on which the sash window slides in the upper frame of the sash outer frame can be freely attached in accordance with the pitch of the rail. By installing the new sash window in the existing sash outer frame of the type that does not have an upper rail, or when installing a new sash window with a different upper frame shape from the removed old sash window by hanging vertically, However, according to the present invention, the upper rail can be provided at a suitable position,
Even when the existing sash outer frame is inclined, the upper rail can be arranged vertically.

Alternatively, the two rails of the sash outer frame are covered with a covering rail member having an inverted U-shaped cross section having a gap wider than the thickness of the rail, and the covering rail member and the rail covered by the covering rail member are covered with each other. By changing the pitch of the two covering rail members by selectively setting the position of the padding member interposed in the gap, it becomes possible to incorporate a new sash window corresponding to various existing rail pitches. .

As described above, according to the sash window replacement method of the present invention, the existing sash outer frame can be used as it is, so that the size of the opening does not change and the sash window does not rise from the floor. The sash window can be replaced very inexpensively without having to occupy the room for a long time for the work to break the wall as described above, and without having to replace the sash outer frame or to perform the coking work.
