Description

[Detailed description of the invention] This invention relates to a mechanism for preventing the shoji from coming off in satsushi etc.
To provide a mechanism for preventing a shoji from coming off, which prevents the shoji from being removed particularly easily, and which always brings the shoji into a non-removal state without any special operation of the mechanism during erection.

For example, in schools, if students are able to remove shoji screens without permission, they may accidentally drop them, and the danger of shoji falling from high floors is well understood without needing explanation. .

For this reason, various mechanisms have been proposed to prevent the shoji from falling off, but the conventional locking mechanisms have a structure that allows them to be easily set to the locked state, so it is difficult to remove the mechanism intentionally. All of them were constructed so that they could be easily removed.

For example, in an example of a locking mechanism in which a locking block that protrudes toward the top of a window frame is attached to the upper stile of a shoji, the locking block is attached with screws.

The screw is located in a position where it can be easily tightened and removed from the indoor side, so anyone with a tool such as a screwdriver can easily remove the locking block.

Therefore, it is extremely dangerous if the retaining block is intentionally removed at a school or the like.

Also, if you forget to install the block to prevent the block from falling off when you erect the shoji, or even if you install it, the amount of protrusion from the upper sash is not sufficient, and if the block is installed with insufficient protrusion, the function of preventing the block from falling off will not work. This situation is also dangerous.

The purpose of this invention is to ensure that the locking mechanism is not easily damaged, but if the shoji is closed or the shoji is moved back and forth at least once within its opening/closing range, the locking mechanism will not be easily damaged. To provide a mechanism for preventing a shoji from coming off, which can be set in a state.

In this invention, a movable element is installed in the lower stile of the shoji and is biased by a spring toward the rail, and the retaining piece of this movable element is dropped downward through a notch formed in the horizontal corner of the rail, so that it can be moved afterwards. The engaging piece of the child engages with the horizontal bar of the rail, and this engagement prevents the shoji from coming off.

An embodiment of this invention will be described below in detail with reference to the drawings.

FIG. 1 shows an example of the main part of this invention.

In the figure, 1 indicates the lower stile of the shoji, 2 indicates the lower frame of the window frame, 3 indicates the rail formed on the lower frame 2, and 4 indicates the horizontal cutout formed at the upper end of this rail 3.

In other words, it is generally considered sufficient that the locking mechanism is attached only to the outer shoji.

Therefore, this example also shows an example in which a locking mechanism is attached to the outer shoji.

In addition, both the outer shoji and the inner shoji are usually removed toward the outdoor side, and therefore, the horizontal cut-out 4 formed on the rail 3 is assumed to protrude from the upper end of the rail 3 toward the outdoor side.

In this invention, a movable element 6 which is biased toward the rail 3 by a spring 5 is provided on the lower stile 1 of the shoji.

The movable element 6 has a retaining piece 7 at its lower end, and this engaging piece 7 faces the horizontal piece 4 of the rail 3.

In other words, during erection, the engagement piece 7 is placed on the horizontal cutout 4 of the rail 3.

When the shoji is moved in this state, a notch is formed in the horizontal cutout 4 of the rail 3, and this notch allows the engaging piece 7 to be moved.
falls to the lower side of the horizontal katakuri 4, and thereafter the engaging piece 7 engages with the horizontal katakuri 4, and even if the shoji is pushed upward, the lower stile 1 will not come off the rail 3.

FIG. 1 shows a state in which the engaging piece 7 has fallen to the lower side of the horizontal potato chestnut 4.

The movable element 6 is made of, for example, a resin material, and has a shape as shown in FIG.

Reference numeral 8 in FIG. 3 indicates a housing that supports the movable element 6. The movable element 6 is housed in a groove 8a of the housing 8, and the movable element 6 is supported by the housing 8 so that it can move only in the vertical direction. Ru.

As shown in FIGS. 1 and 4, the housing 8 is attached to the lower frame 1 from the outside using screws 9.

10 is a screw hole for fixing this screw.

Holes 6 a and 6 b are formed in the upper surface of the movable element 6, and the spring 5 is inserted into the holes 6 a and 6 b.

The upper end of the spring 5 engages with a member of the lower stile 1, and its reaction force presses the mover 6 downward.

A recess 6C is formed on the outdoor side surface of the movable element 6, and a hole 6d is formed in this recess 6C.

The outdoor surface of the lower stile 1 has a length (Lll) as shown in Figure 4.
is formed, and this elongated hole 11 corresponds to the hole 6d formed in the mover 6.
to face.

The hole 6d is used when removing the shoji, which will be described later.

When construction is completed, a rubber decorative button 12 is fitted into the elongated hole 11 as shown in FIG. This prevents the movable element 6 from floating up.

Next, the positional relationship between the mover 6 and the notch formed in the horizontal cutout 4 of the rail 3 will be explained.

Figure 5 shows the relationship.

In FIG. 5, 13 indicates a window frame. 2 is the lower frame as explained in FIG.

14 indicates Kamizusa, and 15 indicates Shoji.

This example shows a case where the mover 6 is attached to the lower stile of the shoji 15 at two locations.

The two movers 6 are mounted apart from each other by an interval.

Horizontal potato starch 4 of rail 3 for these two movers 6-6
Cutouts 16-16 are also formed spaced apart by a similar distance.

In this example, the notch 16-16 is formed at a position where the mover 6-6 falls when the shoji 15 reaches the window closing position.

A locking body 18-18 (see FIG. 6) is attached to the upper frame 14 facing the vertical stile of the shoji 15 in the window closed position.

This locking body 18-18 is attached to the upper end of the vertical frame of the shoji 15 when the shoji 15 is in the closed position, that is, when the shoji 15 is pushed upward in a position where the mover 66 is facing the notch 16-16. This collision regulates the amount of push-up of the shoji 15.

The amount of restriction is selected within a range in which the engaging piece 7 of the movable member 6-6 does not rise above the horizontal corner 4 of the rail 3.

Note that 19 is a third locking body.

That is, when the shoji 15 is opened, there is a position where the movable element 6 on the left side of the figure faces the notch 16 on the right side.

If the left side vertical stile of the shoji 15 is lifted in this position, the movable element 6 will be lifted above the horizontal potato chestnut 4 through the notch 16, and there is a possibility that the movable element 6 will be disengaged from the horizontal potato chestnut 4.

For this purpose, a third locking body 19 is provided, so that when the left movable element 6 is in a position facing the right notch 16, the movable element 6 will not come off the horizontal Katakuri 4 even if the left vertical stile of the shoji 15 is lifted. That's what I do.

To remove the shoji 15 from the window frame 13, first place the shoji 15 in the closed position.

In this position, the mover 6-6 faces the notch 16-16.

Therefore, the decorative button 12 is removed from the outdoor side, a rod-shaped object is inserted into the hole 6d formed in the recess 6C of the movable element 6, and the movable element 6-6 is lifted upward against the biasing force of the spring 5. In this state, move the shoji 15 a little in the direction of opening the window.

Due to this movement, the movable element 6-6 is removed from the position of the notch 16-16, so that when the force for lifting the movable element 6-6 is released, the movable element 6-6 is held in a state on the horizontal potato chestnut 4.

Therefore, in this state, the shoji 13 can be freely removed from the window frame 13.

FIG. 7 shows another example of the formation position of the notch 16.

In this example, the notches 16 are formed at intervals W different from the mounting intervals of the movers 6-6 attached to the shoji 15, and when the shoji 15 is in a position other than the closed window position, the movers 6
6 is shown.

In this case, the locking body 18 is attached to face the upper end of the left stile of the shoji 15 when the left movable element 6 is in the illustrated state facing the left notch 16.

Further, when the right movable element 6 faces the right notch 16, the locking body 18 is attached so as to face the upper end of the right stile.

In this way, when removing the shoji 15 by making the mounting interval W of the notches 16 different from the mounting interval of the movable element 6, the movable element 6
can be removed from the holding state of the horizontal potato 4 one by one.

Therefore, even large shoji screens can be removed by one person.

Further, since the position where the notch 16 and the movable element 6 face each other is selected at an arbitrary position where the shoji 15 is in an open state, open portions on both sides of the shoji 15 are formed.

Therefore, the movable member 6 is inserted into the long hole 11 formed in the lower stile 1 from the indoor side.
Since the lifting operation can be performed from both sides of the shoji 15, even large shoji can be removed while staying indoors.

As described above, according to this invention, the mover 6 is attached to the lower stile 1 from the outdoor side with the screws 9, so there is no risk of it being easily removed from the indoor side.

In addition, in this invention, the movable element 6 is constantly pressed against the horizontal lattice 4 of the rail 3 by the biasing force of the spring 5, and the engaging piece 7 of the movable element 6 falls to the lower part of the horizontal lattice 4 through the notch 16 formed in the horizontal lattice 4. Because it was configured so that the shoji 15
If you open and close it at least once, the mover 6 will always open and close the notch 1.
To provide a highly reliable mechanism for preventing a shoji from coming off by simply opening and closing a shoji 15 to dynamically put the shoji in a non-receiving state without forgetting to set the shoji to a non-removal state. Can be done.
