Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for preventing a shoji from falling off a sash opening/closing window.

A sash opening/closing window generally has an outer shoji and an inner shoji slidably mounted inside a rectangular frame. Therefore, there is a risk that the outer shoji may fall off the frame due to warping of the frame or poor installation. especially,
Satoshi opening/closing windows in schools, etc. are prone to deformation because children and students often ride on the lower frame of the frame.
The engagement between the frame and the shoji is shallow, making it easy for the shoji to fall off. Moreover, it is clear that the higher the building is, the greater the risk of a shoji falling off, and there is a desire to develop a device that can reliably prevent shoji from falling off.

The present invention has been made in response to such demands. Under normal conditions, the retaining member and the upper horizontal member are in a state where they can come into contact with each other, and the lower horizontal member cannot be lifted until it passes the lower rail. This prevents the lower horizontal material from dodging the lower rail and causing the shoji to come off.
Even if the shoji comes off, the retaining material engages with the upper horizontal members of the shoji to support the shoji and prevent it from falling, and if necessary, the retaining material can be slid by a simple external operation. This allows the shoji to be removed.

The invention will now be described with reference to the illustrated embodiments.

The frame 1 of the sash opening/closing window consists of a rectangular assembly of an upper frame 2, a lower frame 3, and a pair of left and right vertical frames 4, 5.
The upper frame 2 and the lower frame 3 each have two upper rails 6 and 7.
and lower rails 8, 9 are provided. and,
Two shoji screens are attached to the frame 1 in a sliding manner. That is, the outer shoji 10 and the inner shoji 11 are
They are slidably mounted between an upper rail 6 and a lower rail 8 on the outdoor side and between an upper rail 7 and a lower rail 9 on the indoor side, respectively, and can be opened and closed in a sliding manner.

Thus, the upper horizontal member 12a of the outer shoji 10 has a horizontal portion 30 facing the lower end of the upper rail 6, and the longitudinal side edge of the horizontal portion 30 has an indoor vertical wall 13.
and an outdoor side vertical wall 13' extend to face each other and have a substantially H-shaped cross section. Above indoor vertical wall 13
A locking edge 14 extends along the longitudinal direction toward the upper rail 6 on the upper edge, and a hook portion 15 that projects downward is provided at the tip of the locking edge 14. The locking edge 14 has two holes near both ends in the longitudinal direction.
Cutouts 16 and 17 through which the retaining member 19 passes are formed at two locations. Further, a horizontal portion 30 of the upper horizontal member 12a corresponding to the passage notches 16 and 17 at approximately the same position.
Horizontally long holes 31 and 32 having approximately the same length as the passage notches 16 and 17 are bored in the holes 31 and 32, and a retaining member 19 described later is formed in the holes 31 and 32.
The fitting piece 19' can be fitted loosely. In addition, the passage notch 16 located on the vertical stile 18 side of the outer shoji 10
is preferably located close to the vertical stile 18.

Further, the upper frame 2 of the frame body 1 is provided with retaining members 19 and 20 corresponding to the passage notches 16 and 17. These retaining members 19 and 20 each have an upright portion 19a or 20a that is slidable on the upper rail 6, a tongue piece 24 extending horizontally from the upper end of the upright portion 19a or 20a, and a raised portion. 19a or 2
Substrate portion 19b extending horizontally from the lower end of 0a
or 20b, a hook-shaped locking portion 26 projecting upward from the tip of the base plate portion 19b or 20b, and a hook portion 21 formed at the lower end of the upper rail 6 toward the indoor side.
A surrounding portion 22 is provided upwardly in the middle of the substrate portion 19b or 20b so as to enclose the substrate portion 19b or 20b. Further, a fitting piece 19' or 20' is provided extending downward from the base plate portion 19b or 20b, and the fitting piece 1
The distance between the lower end of 9' or 20' and the upper surface of the horizontal part 30 of the upper horizontal member 12a of the outer shoji 10 attached to the frame 1 is narrower than the width of the lower rail 8 and the lower horizontal member 12b. It has been formed. Also, the retaining material 19,
The distance between the locking portion 26 of 20 and the locking edge 14 of the upper horizontal frame 12a is also narrower than the width of the engagement between the lower rail 8 and the lower horizontal frame 12b.

The tongue piece 24 formed on the above-mentioned detachment prevention members 19 and 20 can be fitted into a guide groove 23 formed in the upper frame 2 of the frame body 1 and opened toward the indoor side, and The surrounding portions 22 of the retaining members 19 and 20 can be engaged with each other. Note that these retaining members 19 and 20 are attached to the upper frame 2 when assembling the frame 1.
It is slidably mounted in advance from either end in the longitudinal direction, and the mounted retaining members 19, 20 will not come off from the upper frame 2 unless the left and right vertical frames 4, 5 are removed.

Then, as described above, the pair of retaining members 1
9 and 20 are attached to the upper frame 2, one side is slidable,
Make the other part fixed. That is, the retaining member 19 located on the side of the vertical stile 18 is slidable in the longitudinal direction of the upper frame 2, and the retaining member 20 located on the side of the connecting stile 29 is used for caulking the set screw 25 or the guide groove 23, etc. It is fixed by means of. The retaining member 19 that is slidable in the longitudinal direction of the upper frame 2 corresponds to the passage notch 16, and the retaining member 20 that is fixed to the upper frame 2 corresponds to the passage notch 16.
corresponds to the passage notch 17. And outside shoji 10
In the initial setting state before fitting into the frame 1, both of the retaining members 19 and 20 are correctly inserted into the passage notch 1.
It is positioned to match the positions (intervals) of 6 and 17. In addition, a slidable retaining member 19
includes a movable protrusion 2 that can extend outward from the side surface of the vertical stile 18 so as to be able to be operated externally when the vertical stile 18 of the outer shoji 10 and the retaining member 19 are in contact with each other.
7 is integrally provided in the sliding direction of the retaining member 19, so that the retaining member 19 can be slid along the upper frame 2 from the outside. Incidentally, in FIG. 4, reference numeral 28 indicates an escape groove for the movable projection 27 provided at the upper end of the vertical stile 18 of the outer shoji 10.

The device for preventing falling of shoji having the above-mentioned structure has the following feature: when fitting the outer shoji 10 into the frame 1, the passage notch 1
6 and 17 are aligned with the retaining members 19 and 20.
Then, when fitting the outer shoji 10 to the frame 1, when the upper horizontal member 12a is passed through the upper rail 6 from below, each passage notch 16, 17 passes through the retaining members 19, 20, and the fitting piece 19' and 20' are horizontal holes 3
1 and 32, and the upper horizontal member 12a is attached to the upper rail 6 without the horizontal parts coming into contact with the fitting pieces 19' and 20'.
can be easily fitted, and the lower horizontal member 12b
The outer shoji 10 can be easily attached to the frame 1 by bypassing the lower rail 8. Conversely, in this state, the function to prevent the outer shoji 10 from falling off is not demonstrated (fifth
Figure A).

However, when the outer shoji 10 is slid toward the open side, the inner surface of the vertical stile 18 eventually comes into contact with the end of the slidable retaining material 19, and the retaining material 19 moves together with the outer shoji 10 onto the upper frame 2. begins to slide in the opening direction along. When the matching frame 29 of the outer shoji 10 comes into contact with the door stop block 2' of the upper frame 2 or the lower frame 3, that is, when the outer shoji 10 is opened to the maximum extent, the movable side retaining member 20 (Figure 5B). Then, the movable side retaining member 19 is temporarily attached to the fixed side retaining member 2.
When it reaches the position where it touches 0, the outer shoji 10
Even if it is closed, this retaining member 19 does not move (Fig. 5C). Therefore, the above-mentioned retaining members 19, 20
is not unevenly distributed in inappropriate positions.

Therefore, the width of each passage notch 16, 17 is
Although it is slightly longer than the width of the individual retaining members 19 and 20, if it is set to be shorter than the sum of the widths of the plurality of retaining members 19 and 20, the upper horizontal member 12a can be held at any position of the outer shoji 10. The locking edge 14 always overlaps the retaining member 19 and/or 20, and the fitting pieces 19', 20' cannot fit into the horizontally elongated holes 31, 32.

Therefore, even if a force is applied to lift the outer shoji 10 and the outer shoji 10 is lifted, the fitting pieces 19', 2
Since the lower end of 0' comes into contact with the upper surface of the horizontal part 30,
The lower horizontal member 12b cannot avoid the lower rail 8, and the outer shoji 10 does not fall off. Moreover, even if the outer shoji 10 should come off the lower rail 8 of the lower horizontal member 12b, the locking portions 26 of one or both of the two retaining members 19 and 20 will attempt to descend. Since the locking edge 14 of the outer shoji 10 is received and the hook portion 15 and the locking portion 26 engage with each other, the outer shoji 1
0 will not fall and can be reliably prevented from falling.

On the other hand, when it becomes necessary to remove the outer shoji 10 from the frame 1, the outer shoji 10 is once slid toward the opening side, and the inner surface of the vertical stile 18 is brought into contact with the retaining member 19. Then, since the moving protrusion 27 projects to the outside of the vertical stile 18 through the relief groove 28 of the vertical stile 18, it becomes possible to hold the moving protrusion 27 and slide the retaining member 19 from the outside. Therefore, while sliding the outer shoji 10 in the closing direction, the movable side retaining member 19 is returned to the initial setting position, and the position of each retaining member 19, 20 and the passage notch 16 provided in the upper horizontal member 12a, 17 so that they match. In this initial setting state, the retaining material 1
The locking portions 26 of 9 and 20 can pass through the locking edge 14 at the passage notches 16 and 17, and
The fitting pieces 19', 20' fit into the horizontally elongated holes 31, 32 to connect the horizontal part 30 of the upper horizontal member 12a and the fitting pieces 19', 2.
The lower cross member 12b does not come into contact with the lower end of 0'.
can avoid the lower rail 8, and the outer shoji 10 can be removed from the frame 1.

In the illustrated embodiment, the fall prevention device is provided only for the outer shoji 10, but this does not preclude the fall prevention device from being provided in parallel to the inner shoji 11.

In summary, according to the present invention, a pair of retaining members having fitting pieces are attached to the upper frame of a frame body made up of an upper frame, a lower frame, and a pair of left and right vertical frames, and one retaining member is attached to the upper frame. The frame can be slid in the longitudinal direction, and the other retaining material is fixed, and the upper horizontal member of the shoji installed on the frame has a passage notch through which the retaining material can pass vertically. It is formed to correspond to the retaining material, and a horizontally elongated hole is provided in the horizontal portion at approximately the same position as the passing notch, and the width of the passing notch is configured to be shorter than the sum of the widths of the individual retaining materials, Since the distance between the fitted piece and the horizontal part is narrower than the width of the lower horizontal member and the lower rail, under normal conditions, the retaining material and the passage notch do not align, making it easy to lift the shoji. Also, the fitting piece of the retaining material comes into contact with the horizontal part of the horizontal frame material, and the lower horizontal frame cannot avoid the lower rail, so the shoji does not fall off, and even if the shoji comes off from the lower rail due to vibration or shock. Even if the locking edge of the retaining member and the hook portion provided on the locking edge of the upper horizontal member engage with each other to support the shoji, the shoji will not come off from the frame and fall downward. Moreover, once the shoji is opened, the slidable retaining material moves to a position that does not coincide with the passage notch, and does not move when the shoji is opened or closed, so the passage notch and the retaining material may accidentally There is no possibility that the shoji will fall off, and there is no possibility that the stopper material will be unevenly distributed at inappropriate positions.

In addition, since each of the retaining members is attached to the upper frame of the frame and hidden inside the upper horizontal member of the shoji screen, it cannot be operated from the outside under normal conditions. Therefore, when applied to a school building, etc., the shoji will not be removed due to mischief by children or the like. However, if it becomes necessary to remove the shoji, first open the outer shoji, extend the moving protrusion from the vertical stile of the outer shoji, and operate the moving protrusion to pass through the position of the retaining material. In this position, the shoji can be removed from the frame by simply lifting it slightly and dodging the lower rail, just like in the past.

Therefore, the present invention is highly safe and effective, especially when applied to schools and other public buildings.
