Description of the Related Art Generally, among sliding doors constructed of sliding doors, inner sliding doors are provided with a rotation locking metal fitting of a crescent lock on a side surface of a door, so that the sliding door is opened when the sliding door is opened. In order to prevent the rotation locking bracket from crashing into the vertical frame each time and deteriorating the mounting state of the rotation locking bracket or deforming a part of the vertical frame, the rotation locking bracket must be A shoji stopper for stopping the inner shoji before hitting is attached to the window frame. And since the shoji may be fully opened in a vigorous manner, in order to stably stop the opened shoji up and down,
The shoji stopper is usually mounted on both the lower frame and the upper frame. When the window frames are all made of metal, there is no problem in attaching the sash stopper to the upper and lower frames with screws or the like.

[0003]

However, in the case where the window frame is a composite sash composed of a metal frame and a resin frame that covers a portion of the metal frame exposed on the indoor side, the upper sash stopper is provided with an inner sash. The upper sash stopper is fixed to the upper frame with screws that penetrate the upper sash stopper, as in the conventional case. It is necessary to penetrate the screw through the screw through hole and screw it into the metal frame. When forming the screw through-hole in the resin frame, the strength around the screw through-hole may be reduced.In addition, it is necessary to screw in the screw, and the problem is that the metal frame and the resin Since the expansion and contraction ratio of the frame due to heat is different, the connection state by the screw is deteriorated within a long period of time, and the sash stopper is loosened and eventually falls off.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a problem thereof is that when a window frame is made of a metal frame and a resin frame, a shoji stopper is easily and securely fixed to the resin frame of the upper frame. Is to be able to do that.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a sliding stopper having a resilient locking projection projecting downward on an outdoor side surface thereof, and forming the locking stopper on the sliding door stopper from the indoor side thereof. A locking plate made of a thin steel plate having a sharp locking claw elastically protruding is provided, and a locking hole for locking the locking projection of the shoji stopper is formed on an outer rail of the resin frame of the upper frame. The sliding stopper is pushed in between the inner and outer rails of the resin frame of the upper frame, and the locking projection is fitted and locked in the locking hole by elastic deformation and restoration; The engaging claw is frictionally engaged with the outdoor side surface of the inner rail by springability and biting. With the above configuration, when the sash stopper is pushed between the inner and outer rails near the end of the resin frame of the upper frame, the locking projection is fitted and locked in the locking hole of the outer rail by elastic deformation and restoration. The locking claw of the metal fitting is firmly frictionally locked to the outdoor side surface of the inner rail by the springiness and biting of the material. Therefore, the shoji stopper can be securely fixed so as not to fall off by a simple operation of simply pushing it between the inner and outer rails at a predetermined position of the resin frame of the upper frame.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described based on the illustrated embodiments. FIG. 1 is a longitudinal sectional view showing a state in which a shoji stopper is attached, and FIGS.
FIG. 8 to FIG. 1 show the shape and structure of a shoji stopper.
FIG. 0 is a view showing the shape and structure of a locking fitting mounted on a shoji stopper.

In FIG. 1, H is an upper frame of a window frame. More precisely, the window frame is a resin frame of an upper frame of a composite sash composed of a metal frame and a resin frame covering a portion exposed to the indoor side of the metal frame, and the metal frame is used for simplifying the drawing. Omitted for clarity. FIG. 1 is for the purpose of showing a main part of the resin frame, and the cross-sectional shape thereof is merely an example.

[0008] 1 is an inner rail for supporting and guiding the inner shoji Di, 2 is an outer rail for supporting and guiding the outer shoji Do,
B is an upper sash stopper which is inserted between the inner and outer rails 1 and 2 of the upper frame H according to the present invention. The upper sash stopper B is provided near a longitudinal end of the upper frame H, that is, when the inner sash Di is opened, a rotating member of a crescent lock protruding from a door bottom surface of a vertical frame (not shown). Bracket (not shown) with vertical frame (not shown)
Just before colliding with the vertical frame, the vertical frame is mounted at a position where the door end surface abuts.

As will be described in detail later, a mounting device for the shoji stopper B includes a locking hole 3 provided in the outer rail 2, a shoji stopper B, and a locking metal member C fixed to the shoji stopper. Has become.

The outer rail 2 is provided with one or a plurality of locking holes 3 near one end of the upper frame H in the longitudinal direction.

On the other hand, the shoji stopper B has a stop portion 4 having a width approximately half the distance from the inner rail 1 to the outer rail 2, and a connecting portion 5 extending from the stop portion in the direction of the outer rail 2.
And The connecting portion 5 extends in the direction of the outer rail 2 from the upper half portion of the stop portion 4 and forms a space on the outdoor side of the lower half portion of the stop portion 4 for escaping the moving area of the upper end portion of the shoji Do. ing. For this reason, the shoji stopper B is formed in a box shape having a laterally L-shaped side surface, a substantially T-shaped front surface, and an H-shaped flat surface. It may be formed in a block shape instead of a box shape. Further, the shape when viewing each surface is not limited to the illustrated one. The expected width of the shoji stopper B, that is, the distance from the indoor side surface of the stop portion 4 to the outdoor side surface of the connecting portion 5 matches the distance between the inner and outer rails of the upper frame. Further, on the front surface of the connecting portion 5, that is, on the surface of the sash stopper B which faces the outer rail 2, there is provided an elastic locking projection 6 which projects downward and corresponds to the locking hole 3 of the outer rail 2. I have. On the back surface of the stop portion 4, that is, on the side opposite to the elastic locking projection 6 of the shoji stopper B, a locking metal member C formed in a protruding edge shape extending upward.
There is provided a mounting portion 7 for mounting the.

As shown by a dashed line in FIGS. 4 and 6, a fitting C is fixed to the mounting portion 7. The latch C is
In order to provide strong elasticity, it is made by bending a thin steel plate into an approximately 7-shaped vertical cross section, and has a fitting groove 8 having a width slightly smaller than the thickness of the mounting part 7 of the shoji stopper B at the upper part, and a lower end part. Is formed with a locking claw 9 having a jagged or other sharp end. Preferably, a rib 10 extending in the vertical direction is formed to provide strength.

The latch C is provided with a shoji stopper B in the fitting groove 8.
By pressing in the mounting portion 7 and pressing it, it is fixed so that it cannot be removed. In that case, the locking claw 9 is
6, and elastically protrudes from the back surface of the stop 4. As shown in FIG. Since the locking metal member C is made of a steel plate, the locking claw 9 can be freely protruded and retracted from the concave portion 4a on the back surface of the stop portion 4 when receiving external force. A plurality of locking holes 7 a are provided in the mounting portion 7, and cut-and-raised pieces 11
When the locking fitting is mounted and cut and raised into the locking hole 7a and the piece 11 is fitted, the falling off of the locking fitting is reliably prevented.

As described above, the sash stopper B having the locking metal fitting C attached thereto, as shown in FIG.
When the locking projection 6 is pushed into the predetermined position between the two, the locking projection 6 is moved until it hits the upper wall uw of the upper frame H in an elastically deformed state so that the amount of protrusion of the connecting portion 5 from the outdoor side surface is reduced, and the upper wall uw When the locking projection 6 is stopped, the locking projection 6 fits into the locking hole 3 of the outer rail and returns, so the locking projection 6 is locked in the locking hole 3. On the other hand, the lower end of the latch C is retracted into a slight recess 4a formed on the back surface of the stop portion 4 while the shoji stopper B is pushed between the rails. Wall uw
After being pushed to the predetermined position where it stops at
The lower end of the inner rail 1 is elastically restored, and is pressed so that the sharp tip of the locking claw 9 pierces the outdoor side surface of the inner rail 1. For this reason, since a large friction locking force acts, the shoji stopper B is also fixed so that the inner rail side cannot fall off.

In FIGS. 4, 5, and 7, reference numeral 11 denotes a screw through hole. When fixing the sash stopper B to a metal upper frame, a screw penetrates the screw through hole 11 so that the upper frame is removed. It can also be screwed to the upper wall. When the screw through-hole 11 is provided as in this example, a screw through-hole slightly larger than the diameter of the screw is formed in the resin frame of the composite sash in consideration of the difference in expansion and contraction ratio between the metal frame and the resin frame. By doing so, with the thermal expansion of the resin frame,
The peripheral edge of the screw through hole of the resin frame is effectively prevented from being damaged by receiving an external force from the screw, and in addition to the connection by the screw, the engagement and engagement of the engagement protrusion with the engagement hole of the outer rail are made. The sliding stopper B is more securely fixed by the frictional locking between the spring property of the stopper and the biting of the sharp locking claw into the inner rail. Such a mounting structure of the upper sash stopper is particularly suitable for a large-sized heat-insulated sash.

FIG. 11 is a sectional view showing another embodiment of the present invention. In this case, the shoji stopper B 'is provided with a stop 4'.
Is formed so as to straddle the inner rail 1, and the engaging claw of the engaging metal fitting C attached to the indoor side surface of the stop portion is pressed against the inner surface of the indoor side wall iw of the upper frame H to frictionally engage the connecting portion 5. The locking projection 6 on the outdoor side is adapted to engage with the locking hole 3 provided in the outer rail. This embodiment also has the same effect as the previous embodiment.

FIG. 12 is a longitudinal sectional view of the composite sash, and FIG. 13 is a transverse sectional view of the same. In FIG. 12, H is a metal frame H
m and an upper frame composed of a resin frame Hp. The metal frame Hm is formed of a metal having excellent weather resistance and mechanical strength, such as aluminum, and the upper frame is fixed to the building frame at two upper and lower locations. To have a mounting edge 1 and 2
Of the outer rail ro that guides the upper frame h. The resin frame Hp is formed of, for example, a resin such as vinyl chloride or acrylic, which is excellent in heat insulation and design, and covers a portion of the metal frame Hm exposed on the indoor side. The upper frame H has a double-walled structure having a hollow portion 4 at a position that does not cause an increase in the expected width, and obtains as large a strength as possible within the restricted thickness range of the inner sash shroud Di. Therefore, in addition to having a hollow inner rail ri having the same cross-sectional shape as the outer rail ro, the hanging edge 5 constituting the indoor side portion of the outer rail ro and the hanging edge 6 at the indoor side end have a single thickness. As a result, the expected width of the upper frame H is made as small as possible. The outer rail ro of the upper frame H has the same cross-sectional shape as the inner rail ri between the hanging edge 3 of the metal frame Hm and the hanging edge 5 of the resin frame Hp.

Sm is a metal frame that constitutes a portion of the lower frame S exposed to the outside, and has attachment edges 7 and 8 for fixing the lower frame to the building frame at two locations above and below. Shoji D
It has inner and outer rails ri and ro for guiding the lower frame s of i and Do. Since the lower frame S supports the load of the window frame itself and the entire load of the shoji, the highest strength is required among the window frames. Therefore, the metal frame Sm has substantially the same shape as the metal frame of the conventional lower frame. And has an inverted L-shaped rain return wall 9 which is locked to a window sill or a table board at the indoor side end. A groove 10 between the rain return wall 9 and the inner rail ri and a resin frame Sp that covers the upper surface of the rain return wall 9 of the metal frame Sm are fitted and mounted in the groove 10.

Jm is a metal frame that constitutes a portion of the left and right vertical frames J1 and J2 exposed on the outdoor side of the window frame, and has a required strength. The resin frame Jp is fitted to the inner surface corresponding to the inner shroud Di of the metal frame Jm at two locations inside and outside, and the screw 11 at the portion where the metal frame Jm and the resin frame Jp overlap each other is formed. They are connected by fastening. Since the vertical resin frame Jp does not have a hollow portion and has a single wall structure, the vertical frames J1 and J
2 is reduced to fit the upper frame H and the lower frame S.

Next, the upper frame h and the lower frame s of the sliding sliding doors Di and Do built on the window frame F respectively include metal frames hm and sm and the exposed portions of the metal frames on the indoor side. It consists of covering resin frames hp and sp. The metal frames hm and sm are formed as thin as before, and the resin frames hp and sp do not have a hollow portion on the indoor side. It is formed as thin as possible. The vertical frame j1 on the door end side (door stop side) may receive a strong collision force from the vertical frames J1 and J2 of the window frame via the pulling member b when opening and closing the shoji, or generate strong wind pressure in the closed state. In order to withstand the impact force and wind pressure, the resin frame jp1 of the vertical frame j1 on the side of the door should have the required strength.
Has a hollow portion td having a minimum thickness.

According to the above embodiment, when the shoji stopper is mounted on the upper frame of the composite sash composed of the metal frame and the resin frame covering the portion of the metal frame exposed to the indoor side, Since the locking holes are provided on the outer rail at the position where the processing is easy, and the locking holes are not provided on the inner rail at the position where the processing is difficult, there is no risk of damaging the resin frame during the processing. Further, the shoji stopper B having the elastic projection 6 is usually made of resin, and the engagement of the projection 6 with the engagement hole of the outer rail is ensured. Even if it is attempted to frictionally lock the inner rail with the locking claws, the locking claws are slippery and cannot be reliably locked because both the shoji stopper and the inner rail are made of resin. However, according to the present invention, the thin metal plate fitting is mounted and the sharp locking claw is pressed against the inner rail, so that the spring property of the material of the locking metal and the locking claw bite into the inner rail. Thereby, a stable locked state can be obtained. Therefore, there is an effect of being securely locked.

[0022]

As described above, according to the present invention, the shoji stopper can be securely fixed simply by pushing it between the inner and outer rails of the resin frame of the upper frame, so that the mounting is easy. Also, in the upper frame of the composite sash in which the window frame is composed of the metal frame and the resin frame, the locking projection of the sash stopper is fitted and locked in the locking hole provided in the outer rail of the resin frame, and the sharpness of the locking metal fitting is improved. The locking claws are pressed against the outer side surface of the inner rail of the resin frame of the upper frame, so the spring property of the material and the biting of the locking claws into the inner rail ensure that the shoji stopper does not slip on the resin frame. The effect of being stably locked is obtained.
