DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a resin frame of a vertical sliding window. This frame 1 is made of a resin material 3
, And is formed by fastening and welding each of the joints 3a.

The frame 1 is provided with a shoji 5 such as a resin sash which can be opened and closed. The sash 5 is assembled in a four-sided frame with a resin material 7, a glass 8 is fitted into the sash 5, and each joint 7 a is fastened and welded.

As shown in FIG. 2, the hollows 7b of the resin profiles 7 located above and below, corresponding to the upper and lower frames, respectively.
A metal back plate 9 (FIG. 3) made of aluminum is provided therein, and the metal back plate 9 is fixed to a predetermined position in the hollow 7b by, for example, a self-tapping screw (not shown).

Between the frame 1 and the shoji 5, two upper and lower resin profiles 7 corresponding to the position of the metal back plate 9 are provided.
As shown in FIG. 1, a friction arm (part) 11 that supports the sash 5 so that it can be opened and closed is attached.

Next, the structure of the friction arm 11 will be described with reference to FIGS.

Referring to FIG. 5, for example, the friction arm 11 includes a frame-side fixing plate 15 fixed to the resin profile 3 of the frame 1 by screws 13, and a screw 1 to the resin profile 7 of the shoji 5.
One end is connected to the first sliding shaft 21 of the sash side fixing plate 19 fixed at 7, and the other end is connected to the second rotating shaft 23 of the frame body side fixing plate 15. First link 2
5 and a second link 31 having one end connected to the third rotation shaft 27 of the shoji-side fixing plate 19 and the other end connected to the fourth rotation shaft 29 of the frame-side fixing plate 15. .

The sliding door 5 is fully closed at the position shown in FIG. 4, opened partway at the position shown in FIG. 5, and fully opened at the position shown in FIG. That is, when the handle 33 shown in FIG. 4 is pushed forward and the handle 33 is pushed forward, as shown in FIG. (Opening degree: 45 °). When the handle 33 is further pushed forward, as shown in FIG. 6, the second link 31 and the shoji-side fixing plate 19 are arranged in a straight line, and the shoji 5 is fully opened.

In this embodiment, as shown in FIG. 2, a metal back plate 9 made of aluminum provided in a hollow 7b of the resin profile 7 is previously provided with a resin profile 7 as shown in FIG. A long hole 35 extending in the longitudinal direction is provided. The pitches P1 and P2 of the elongated holes 35 are formed to be equal to the pitches P1 and P2 (FIG. 5) of the screw holes 17a of the frame-side fixing plate 15 constituting the friction arm 11.

Then, as shown in FIG.
Is applied to the shroud-side fixing plate 19 having the screw hole 17a on the resin profile 7 located behind, and the screw 17 inserted into the screw hole 17a of the shoji-side fixing plate 19 passes through the resin profile 7, The shoji-side fixing plate 19 is screwed into the long hole 35 of the metal back plate 9 and fastened to the resin profile 7.

In the conventional configuration, the metal back plate 9 is not provided with a pilot hole for a fixing tool, and the sliding arm side fixing plate 19 of the friction arm 11 is self-tapping screw (not shown).
Since the screw is fixed to the back plate, for example, only the tip of the screw is applied to the back plate 9 and the holding force is weakened when the screwing is reduced, and an excessive force is required for the tapping operation. This work became heavy labor.

In this embodiment, since the elongated hole 35 for the fixing tool (screw 17) is formed in the metal back plate 9, the self-tapping screw (not shown) is used without using a self-tapping screw (not shown).
As shown in (1), it can be fixed with a screw 17 having a strong holding force.

Accordingly, the fixing plate 19 on the sash side of the friction arm 11 can be firmly fixed, and the operation of screwing in the screw 17 having a high holding force does not require a large force. Can be reduced.

Further, referring to FIG. 1, since each of the joints 7a of the resin profile 7 of the sash 5 are fastened and welded, the metal back plate 9 is fixed to the resin profile 7. In some cases, the metal back plate 9 may be slightly shifted with respect to the direction of arrow A.

In this embodiment, since the long holes 35 are previously formed at the same pitch P on the aluminum back plate 9 made of aluminum, as shown in FIG. The positional deviation of the screw 17 is allowed by the amount. Therefore, even when the metal back plate 9 is slightly displaced with respect to the direction of the arrow A in FIG. 1 during the manufacture of the shoji screen 5, the friction arm 11 can be easily attached to a regular position.

The position of the screw 17 is determined by the metal back plate 9.
No matter how much the length of the long hole 35 is displaced in the longitudinal direction, it has been confirmed that the sash-side fixing plate 19 can be firmly fixed as long as the screw thread of the screw 17 covers the hole wall of the long hole 35. .

Although the present invention has been described based on one embodiment, it is apparent that the present invention is not limited to this. For example, in the present embodiment, the example in which the shoji-side fixing plate 19 of the friction arm 11 is fastened to the resin-shaped member 7 is not limited to this. This can also be applied when fastening to the material 7. Further, although the elongated holes 35 are provided in three places, it goes without saying that these may be combined into one elongated hole.

[0026]

According to the present invention, since a long hole for the fixing tool is formed in the metal back plate, a large force is not required for screwing the screw. Can be reduced.

Further, in the present invention, since the metal back plate has the long holes, the positional deviation of the screw is allowed by the width of the long holes in the longitudinal direction.
