In an internally removable type sliding sash window in which a retaining protrusion extends from the inside lower part of the lower stile of the outer shoji that is fitted on the rail so that it can be opened and closed freely, to the lower part of the inner lower rail,
This invention relates to a shoji fall prevention device that is installed on the outer shoji retaining ridges.

[Background technology and issues to be solved in the background technology]

FIG. 1 shows the structure of a conventional sliding sash window that can be removed from the inside. That is, in FIG. 1, the sash window frame 1 consists of an upper frame 2, a lower frame 3, and left and right vertical frames 4.
Outer and inner upper rails 5 and 6 are vertically provided from the bottom frame 3, and an outer lower rail 8 and an inner lower rail 9 are respectively protruded from the lower frame 3 with a space 7 in between. Seal surface 1 facing the outer lower rail 8 side at the bottom of the
0 is provided protrudingly.

The outer and inner shoji 11, 12 also consist of upper frames 13, 14, lower frames 15, 16, left and right vertical frames 17, 18, and left and right glasses 19, 20 fitted into these frames. , door wheels 21 and 22 supported on the outer and inner lower rails 8 and 9 are pivotally supported on each lower stile 15 and 16, and each fitting portion 23 and 24 of each upper stile 13 and 14 is The outer and inner upper rails 5 and 6 are received, and the outer shoji 1
From the inner lower part of the lower stile 15 of 1, the sealing surface 1
A retaining protrusion 25 having a support portion 26 facing 0 is extended. Note that 27 is a sealing member provided on each support section including the support section 26.

However, in the inside removable type sliding sash window constructed as described above, the outer and inner sashes 11 and 12 are attached to and removed from the window frame 1 in the following manner. That is, for installation, from inside the window frame 1, first insert the upper stile fitting part 23 of the outer shoji 11 into the outer upper rail 5 and lift it upward.
Fit the lower stile door wheel 21 onto the outer lower rail 8,
Next, the inner shoji 12 is fitted in the same way in order, and for removal, the inner shoji 12 is first inserted from the inside of the window frame 1 by the reverse procedure.
Then, the user is operated to sequentially remove the outer shoji 11. In the case of this type of inner removable type, the retaining protrusion 25, which is a part of the outer and lower stile, is formed at the bottom of the inner shoji, so during normal use, force is applied to lift the outer shoji. In this case, the retaining protrusions 25 come into contact with the inner shoji, and the outer shoji does not come off and fall off. However, if an abnormally large force is applied, if the shoji or frame is deformed, or if there are abnormal fluctuations in the vertical adjustment of the shoji door roller, there is a risk that the outer shoji will come off. Therefore, in order to prevent the outer shoji 11 from falling off due to various reasons, a falling prevention device is installed.

As shown in FIG. 2, a conventional falling-off prevention device of this type includes a falling-off preventing member 28 having a vertically elongated hole 29 at the top of the vertical frame 17 of the outer shoji 11.
is temporarily fixed with the fixing screw 30, and after installation, the elongated hole 29 is used to push up this retaining member 28 upward and fix it. To make it impossible to fall off, or as shown in Figure 3,
A similar effect can be obtained by attaching retaining members 31 at several locations on the upper frame 2, or by combining the retaining members 32 and a wedge member 33 that pushes it upward, as shown in FIG. Each configuration has been proposed to achieve this.

However, in the case of these conventional configurations, in order to restrict the upward lifting of the outer shoji 11, the upper part of the upper stile 13, the vertical stile 17 or the upper frame 2, that is, the tip of the window frame 1, cannot reach. Because the shoji has to be installed on a difficult upper part, the work of installing and removing the shoji is extremely complicated and troublesome, which not only lacks workability but also poses difficulties in the installation and removal operation itself. It was hot.

A common drawback of the above-mentioned known examples is that when attaching or removing the shoji, the worker must stand on the bottom frame and work in an upward position; I was forced to perform on my side, with half of my body hanging out. In particular, when working at heights above the second floor, there is a risk that the worker himself or herself may fall, and there is often a risk that installation tools and parts may fall. is considered an important responsibility.

[Disclosure of invention]

This invention aims to improve these conventional problems by extending a retaining protrusion from the inside lower part of the lower stile of the outer shoji, which is fitted on the outer lower rail so that it can be opened and closed, to the lower part of the inner lower rail. In the case of a sliding sash window, a device for preventing falling of a shoji is provided, in which a hanging piece that can be raised and lowered at an appropriate position of a retaining protrusion is hung down, and this hanging piece provides a falling prevention effect.
The lower frame that makes up the window frame has an outer lower rail and an inner lower rail, and a retaining protrusion is installed at the lower part of the inner lower rail from the inner lower part of the lower frame of the outer shoji, which is fitted on the outer lower rail so that it can be opened and closed. In a sliding sash window of the inner removable type in which the inner side is extended, the width is such that a predetermined distance is left between the inner surface of the lower outer rail, and the side edge on the inner and lower rail side is locked to the upper edge. A hanging piece is provided with an operating fin having a protruding piece standing up and a locking edge formed at the tip, and the hanging piece is attached to one end side of a support plate attached to the lower surface of the retaining protrusion at a proper place. The proximal end of
It is pivotably supported by a support shaft orthogonal to the rail direction so that it can be rotated up and down, and a locking spring is disposed on the other end to lock the locking edge when the operating fin is pulled up. An opening/closing plate is provided with a base attached to the upper surface of the stopper ridge so that it can be opened, closed, and locked, and a slit opening capable of pulling up the operating fin and a locking protrusion of the operating fin are anchored to this opening/closing plate. This is a device for preventing a shoji from falling off in a sliding sash window, characterized in that a recessed portion is formed.

〔Example〕

Hereinafter, one embodiment of the device for preventing falling of a shoji in a sliding sash window according to this invention will be described in detail with reference to FIGS. 5 to 9.

5 and 6 show the main parts of the window structure to which this embodiment device is applied, and in each of these figures,
The same reference numerals as in the conventional apparatus shown in FIGS. 1 to 4 represent the same or corresponding parts.

In the configuration of this embodiment, the fall prevention device has a support plate 40 and an opening/closing plate 41.

As will be described later, the support plate 40 is located on the lower surface of the retaining protrusion 25, and one side edge of the support plate 40 is attached to the support portion 26 with a slight gap left. On one end side of this support plate 40, an outer shoji 11 is fitted onto the lower outer rail 8.
The proximal end of the hanging piece 42, which is wide enough to leave a predetermined distance between it and the inner surface of A bent piece 44 as a rotation stopper and a locking spring 45 for locking the hanging piece 42 in the upright position are provided.

Further, the hanging piece 42 has an operating fin 46 raised up from one side edge on the supporting part 26 side, and a locking protrusion 47 is provided protruding from a part of the inner side of the upper edge of the operating fin 46. A folded piece 48 is provided on the other end edge on the lower outer rail 8 side, and a rib 49 and escape hole 5 are provided on the plate surface.
0 respectively, and a locking edge 51 to be locked by the locking spring 45 is provided at the tip.

Further, as shown in FIGS. 7 and 8, the opening/closing plate 41 has an engaging ring 52 with a hook on the lower surface of the base.
A slit opening 55 for receiving the operating fin 46 and a concave portion 56 for anchoring the locking protrusion 47 are formed on the plate surface portion which is protruded and can be freely opened and closed using the hinge portion 54 as a fulcrum. Furthermore, a hooking recess 57 and a locking protrusion 58 are formed on the lower surface of the tip.

As shown in FIG. 9, the retaining protrusion 25 includes an engaging recess 59 that engages the upper end of the bent piece 44 as a rotation stopper, and an engaging recess 59 that engages the upper end of the bent piece 44 as a rotation stopper.
6, a countersunk hole 61 for mounting, a locking hole 62 to lock the locking ring 52, and a locking hole 63 to removably lock the locking protrusion 58. It has been formed.

These assemblies are carried out as follows. That is, first, the support plate 40 is stopped from rotating by engaging the bent piece 44 in the engagement recess 59, and using a stop screw 64 such as a countersunk screw through the countersink hole 61,
It is installed so that the mounting surface is flat, and the operating fin 46 of the hanging piece 42 is pulled upward through the slit opening 55, and its tip end locking edge 51 is locked and held by the locking spring 45. put.
Next, with the operating fin 46 of the hanging piece 42 and its locking protrusion 47 received through the slit opening 55, the base locking ring 52 of the opening/closing plate 41 is fitted into the locking hole 62 of the retaining protrusion 25. The locking protrusion 58 is lightly locked in the locking hole 63 by fitting and pushing the locking protrusion 58 into the locking hole 63.

Therefore, when assembled in this manner, the operating fin portion 46 is projected upward through the respective slit openings 60 and 55 on the opening/closing plate 41 that is in close contact with the retaining protrusion 25, and the hanging piece having the operating fin portion 46 is 42 is maintained in a state where the locking edge 51 is locked by the locking spring 45 and held at that position, that is, in a non-operating state.

Therefore, the outer shoji 11 is now fitted to the window frame 1, and the protruding operating fin 46 is applied to the elastic force of the locking spring 45 against the fall prevention device that is maintained in an inactive state. If you push it down manually from above, the locking by the locking spring 45 is released, the hanging piece 42 is accompanied by the operating fin 46, and the locking protrusion 47 is rotated around the support shaft 43. It is rotated and suspended to a position where it is moored to the concave portion 56, and is in an operating state. When the next inner shoji 12 is fitted in this operating state, the hanging pieces 42 are located below the outer shoji 11 and extend toward the space 7, and as a result, the outer shoji 11 is The lower length is extended closer to the lower outer rail 8, and the intended falling-off prevention effect is achieved here.

In the above operation, after the outer shoji 11 is fitted, the operating fin 46 is manually pushed down from above against the elastic force of the locking spring 45 to operate. As shown in FIG.
If the inner shoji 12 is set to correspond to the entire lower edge of the lower stile 16, the inner shoji 12 can be placed next to the outer shoji 11 without having to manually operate it as described above.
By the fitting operation, the lower edge of the lower stile 16 can similarly be used to push down the operating fin 46.

Further, in order to return to the non-operating state from the operating state, for example, insert a screwdriver or the like into the tip hook recess 57 of the opening/closing plate 41, pry it up, and use the hinge portion 54 as a fulcrum to push it open. , the concave portion 56 of the opening/closing plate 41 pulls up the operating fin portion 46 and, in turn, the hanging piece 42 while retaining the locking protrusion 47, so that the hanging piece 42
The locking edge 51 of the shoji 11 can be locked to the locking spring 45, and then the opening/closing plate 41 can be closed again, and in this non-operating state, the outer shoji 11 can naturally be removed. .

That is, when installing the outer shoji in this way, the operating fin of the hanging piece that has been pulled up on the opening/closing plate is moved downward by manual operation or automatic operation by collision with the front lower edge of the lower stile of the inner shoji. By rotating and hanging the outer shoji, it is possible to prevent the outer shoji, and by extension, the inner shoji, from detaching and falling.Also, by opening the opening/closing plate and retracting the operating fins, it is possible to easily prevent the outer shoji from falling off. By solving this, we can make them detachable.

[Effect of idea]

As detailed above, according to this invention, the lower frame of the window frame has an outer lower rail and an inner lower rail, and the outer shoji lower frame is fitted onto the outer lower rail so as to be openable and closable. In a sliding sash window of the inside removable type in which a retaining protrusion extends from the inner lower part to the lower part of the inner lower rail, there is a support plate attached to the lower surface of the retaining protrusion at the appropriate place, and a support plate attached to the support plate in the rail direction. The hanging piece is provided with a hanging piece whose base end is pivoted by orthogonal support shafts and can be rotated up and down, and the hanging piece has a locking protrusion on the upper edge on the side edge on the inner lower rail side. In addition to raising the operating fin, we have provided an opening/closing plate that pulls up the operating fin and a locking spring that locks the operating fin in the raised position. By unraveling it and letting it hang downward, it is possible to prevent the outer shoji, and eventually the inner shoji, from falling off. That is, even if the shoji were to be lifted upwards, the hanging pieces would prevent the shoji from coming off. Furthermore, during installation and removal work, the worker can work comfortably without being forced to take an upward posture, and does not have to expose half of his or her body to the outside, so the safety of the worker is sufficiently ensured. Additionally, unlike conventional devices that are attached to window frames, upper frames, etc., work can be done at the bottom of the lower frame, etc., so there is almost no risk of parts or installation tools falling, making it extremely safe and suitable for use in high places. It has an extremely excellent effect as a device for preventing the removal of windows, etc. In addition, by simply opening and closing the opening/closing plate, the operating fins can be pulled up and locked again, making the outer shoji removable, which is extremely easy to operate, and can reliably prevent it from falling off. Moreover, it has various practical effects such as having a simple structure and being able to be provided at low cost.
