DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding frame for a shoji, which is composed of a metal frame body and a synthetic resin resin cover, and has a pull bar at a portion corresponding to the pull bar of the frame body. The present invention relates to a mounting structure for mounting a cap.

2. Description of the Related Art Generally, a sash frame 2 is slidably housed.
When the sliding doors are in the closed state, the mating frame of the vertical frames on both sides of each sliding door is at the center of the sash frame, and only the upper and lower ends are held by the grooves or rails of the upper and lower frames of the sash. In contrast, the other vertical frame located on both sides of the sash frame, opposite the mating frame, has its entire length engaged with the inner edge of the sash vertical frame. For this reason, when strong wind pressure is applied to the shoji, such as in the case of a strong wind, the vertical frames on both sides do not bend because they are held by the protruding edges of the sash vertical frame. Is not supported by the sash frame at all, and the sash may be curved. In order to prevent this, a pull-bar for reinforcement is usually formed on the inside frame of the shoji screen to protrude toward the inside of the room. I also use the trick. The upper and lower ends of the pull bar are cut out to interfere with the sash upper and lower frames on the indoor side when the inner sash is opened and closed, and a pull bar cap is attached to the notch. In addition, since the summing frame of the outer sash is reinforced integrally with the summing frame of the inner sash by the crescent lock, it is not necessary to provide a special reinforcing portion.

[0003] As a heat insulating sash, a composite sash in which a sash frame and a shoji are made of metal and synthetic resin, respectively, is known. The shoji of the composite sash has a frame body formed of a metal frame such as aluminum, and a portion facing the indoor side formed of a synthetic resin frame. Such a composite frame is disclosed in, for example, Japanese Patent Application Laid-Open No. Hei 8-260821. JP-A-8-17731
As shown in No. 7, etc., only the upper and lower stiles and the vertical stiles including the mating stalls were butt-connected. As seen in these examples, conventional composite sashes did not have a pull bar for reinforcement.

[0004]

However, when there is no pull bar, the resin frame is required to have high strength, so that it is necessary to increase the sectional area. Therefore, the sectional area of the resin frame must be increased. However, there is a problem that the molding is complicated and the production cost is increased.

[0005] In view of this, it is conceivable that a pull bar is formed on a metal frame in the same manner as a general aluminum sash to secure the strength, and a pull bar cap is attached to the cutouts at the upper and lower ends of the pull bar. With synthetic resin, synthetic resin has a larger expansion and contraction ratio due to temperature change, and when the outside air temperature falls, the resin frame shrinks more greatly, so a part of the metal frame is exposed from the back side of the resin frame and looks beautiful May be impaired.

The present invention solves the above-mentioned problems, and can secure the strength of a combined frame by forming a pull bar on a metal frame body and covering the frame body with a synthetic resin resin cover. It can be manufactured at low cost together with the pull bar cap provided at the notch at the upper and lower ends of the pull bar, and can prevent the metal frame body from being exposed by fixing the pull bar cap to the resin cover. It is an object to provide a bar cap mounting structure.

[0007]

In order to solve the above-mentioned problems, a pull bar cap mounting structure for a door frame for a shoji according to the present invention comprises a metal frame main body and an indoor side thereof. And a resin cover made of a synthetic resin that is covered by being polymerized on the part facing the side, a pull bar is formed on the frame body, and the upper and lower ends of the pull bar are cut out, and a portion corresponding to the notch of the resin cover is formed. A pull bar cap made of synthetic resin is abutted, a leg portion is formed on the pull bar cap, which is disposed inside the resin cover, and the leg portion is fixed to an inner wall of the resin cover. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 and 2 show the arrangement of two sliding sashes in an ordinary composite sash. Reference numeral 1 denotes an inner sash, 2 denotes an outer sash, and 3 denotes an inner sash. Shows a combination frame.

The frame 3 comprises a metal frame main body 4 and a resin cover 5 made of a synthetic resin and covered with a portion facing the indoor side. Further, a pull bar 6 is formed to project from the room side of the frame body 4, and a pull bar cap 7 is attached to the upper and lower ends of the pull bar 6.

The frame main body 4 is made of an extruded aluminum material or the like, and as shown in cross section in FIG. 3, a parallel room forming two hollow portions 8a and 8b, a smoke return 9 and a fitting groove 10 of double glass. Outer protruding edges 11 and 12 are provided, and an engagement groove 13 is formed at a corner of one hollow portion 8a. Also, as shown in FIG. 4, the lower end (upper end) of the pull bar 6
Are cut out to form notched portions 14, and similarly, at the upper and lower ends are formed notched portions 15a for receiving rail-shaped sash guide means (not shown) formed above and below the sash frame. ing.

The resin cover 5 is also made of a synthetic resin such as vinyl chloride, and has two cover portions 5a and 5b formed in an L-shape. A soft airtight piece 17 is formed integrally with the bent portion of the engaging edge 16 along the entire length thereof. A substantially L-shaped protruding edge 1 is provided on the edge of the other cover 5b.
8 form an engagement groove 19. As shown in FIG. 4, the lower end (upper end) of the portion corresponding to the pull bar 6 is also formed with a concave notch 20 corresponding to the notch 14 of the frame main body 4, and a concave for receiving the sliding means guide means. Fifteen
b is formed.

As shown in FIG. 5, the resin cover 5 engages the engaging edge 16 at one end with the engaging groove 13 of the frame body 4 and simultaneously engages the engaging groove 19 at the other end with the frame main body. 4 is mounted so as to cover the frame body 4 by sliding with the tip of the indoor side protruding edge 11 engaged. At this time, the upper and lower ends of the two are almost aligned, but the notch 1
4. Only the concave notch 20 is provided with the resin cover 5 extending beyond the frame body 4. A space S is formed between one of the cover portions of the resin cover 5 and the frame body 4. Preferably, the color of the pull bar cap 7 is the same as the color of the five resin covers.

Next, a synthetic resin pull bar cap 7 is attached to the concave portion 20 of the resin cover 5. As shown in FIGS. 3 and 4, the pull bar cap 7 is formed so as to cover a portion corresponding to the pull bar 6, and the end face on the base 22 side thereof is formed in the concave notch 20 of the resin cover 5 corresponding to the pull bar 6. It is formed so that it abuts against the end face, and the front side approaches the center of the frame, the surface is inclined, and the whole becomes slightly tapered. Also, from the end face on the base 22 side, the leg 23
Are formed to protrude. The leg 23 is formed so as to fit into the space S formed between the resin cover 5 and the frame main body 4, and one end of the leg 23 is fitted into the engagement groove 19 of the resin cover 5. Is formed. Further, as shown in FIG. 6, the length L1 of the leg portion 23 is set to be smaller than the distance L2 between the end of the frame body 4 and the end of the resin cover 5. In the center of the back surface, a groove 2 is formed in the longitudinal direction.
4 are formed.

When the pull bar cap 7 is attached to the pull bar 6, an adhesive 25 (for example, a butyl-based adhesive) is applied to the front side of the leg 23, and then, as shown in FIG.
Into the space S between the resin cover 5 and the frame body 4,
The end face on the base side is brought into contact with the end face of the concave notch 20 of the resin cover 5. The leg portion 23 is adhered and fixed to the inner wall of the cover portion 5b of the resin cover 5. At this time, a gap is formed between the end face of the frame main body 4 and the tip of the leg 23, which is larger than the difference in expansion and contraction caused by the temperature change between the metal and the resin. In addition, the pull bar cap 7 is provided on the frame main body 4 forming the space S.
It is supported from the back side by two edges 26,27. One of these two edges 26 is the groove 2 of the pull bar cap 7.
4, the pull bar cap 7 is held so as not to swing right and left. In addition, since the two edges only contact the back surface of the pull bar cap 7 and move only along the back surface of the pull bar cap 7 even if it expands and contracts, the pull bar cap 7 expands and contracts. It cannot be moved in any direction.

The means for fixing the leg portion to the inner wall of the resin cover may be a metal fitting having an appropriate structure other than the adhesive.

[0016]

According to the present invention, since the pull bar is formed on the metal frame body and the frame body is covered with the synthetic resin cover, the strength of the combined frame is secured by the pull bar. In addition, since the resin cover does not need to have a complicated cross-sectional structure like a conventional resin frame, it can be manufactured at low cost.

Further, since the resin cover has a pull-bar cap made of synthetic resin fixed to the portion corresponding to the cutouts at the upper and lower ends of the pull bar of the frame main body, the outside air temperature is reduced, and the resin cover is attached to the frame main body. Even if it shrinks greatly and a part of the frame body protrudes from the end of the resin cover, this metal part is hidden behind the pull bar cap and is not exposed to the indoor side. Therefore, the appearance is always maintained regardless of the temperature change.
