Description

[Detailed Description of the Invention] This invention relates to a safety device for a reversible horizontal rotating window.

Built-in blind 1 as shown in Figure 1
A horizontal axis rotating window that can be rotated 180 degrees is well known, and this horizontal axis rotating window is large and tall and can be rotated 180 degrees to clean the outside surface of the shoji 2 from the indoor side.
When performing maintenance on the blind 1, as shown in Fig. 2, when the worker cleans the area above the rotating shaft 3, the operator moves from the position of the shoji 2 indicated by the solid line to the position indicated by the two-dot chain line. There was a risk that the shoji would flip back to 2' and 2 and be thrown outside the room, causing a major accident. For this reason, in the past, safety belts were fixed at some point on the indoor side to ensure work safety, but the fixing work was complicated, had to be prepared each time, and was not reliable. Improvement was desired.

This idea was made based on the above request, and a safety device is detachably attached to the shoji stile and the indoor side to connect the horizontal rotating window when the two are reversed, thereby ensuring work safety. To provide a safety device for a horizontal rotating window that can be used without complicated operations when necessary, and can be stored without any trouble in rotation when not in use.

Hereinafter, this invention will be explained in detail based on FIG. 1 and FIGS. 3 to 9.

In Figures 1 and 3, the shoji 2 is the left and right vertical frame 2.
It is pivotally supported by a rotating shaft 3 to a vertical frame 6a at approximately the center of the vertical frame 2a, and a groove 2b is formed in the surface of the vertical frame 2a facing the vertical frame 6a. Reference numeral 4 indicates a safety device according to this invention, in which the connection between the shoji 2 and the indoor side is released when the window is closed, and the connection is made when the shoji 2 is reversed (the shoji 2 shown by the solid line in Fig. 3). There is.
The safety device 4 includes a rod-shaped member 5 attached to the shoji 2.
, a fixing member 12, and a fixing receiving member 7 that is attached to the window frame 6 or the indoor side of a window opening of a building.

As shown in FIG. 4A, the rod-shaped member 5 is rotatably supported at one end of the arm 8 in the groove 2b by a pivot 9 on a hat-shaped mounting plate 10, and at the same time, the rod-shaped member 5 is rotatably supported on a hat-shaped mounting plate 10 at one end of the arm 8 in the groove 2b. A fixing member 12 is attached to the same side as the plate 10 via a magnetic plate 11 made of iron or the like by a coil spring 14 so that it can freely move in and out in the anti-threading direction of a threaded portion 13 formed at its tip, and then removed. It is set up to be impossible. Here, the shaft hole 15 of the mounting plate 10 through which the pivot shaft 9 is inserted is formed to have a somewhat larger diameter than the diameter of the pivot shaft 9, and the arm 8 as shown in FIG.
An appropriate clearance is provided so that the mounting plate 10 can be rotated in an inclined state with respect to the mounting plate 10.

As shown in FIG. 5, the fixed receiving member 7 is a rectangular body having a threaded groove formed in the substrate to be threadedly engaged with the threaded portion 13 of the fixed member 12, and a protrusion having an inclined upper surface. .

Thus, the rod-shaped member 5 has its mounting plate 10 fixed in a groove 2b located above the rotating shaft 3 on the surface of one vertical stile of the shoji 2 facing the window frame 6, and is attached to the vertical stile. As shown in FIGS. 1 and 4, a lock made of a magnet is installed in a groove in the vertical frame above the fixed position of the mounting plate 10. Member 16
By fixing the magnetic plate 11 with the locking member 16, when the shoji 2 is closed or rotated, the rod-like member 5 hangs down and opposes the vertical frame of the stile so that it does not get in the way. It is designed to be fixed to a surface.

FIG. 6 is a cross-sectional view simultaneously showing the position of the shoji 2' when the window is closed and the position of the shoji 2 when it is turned 180 degrees. It is fixed at a predetermined position on the vertical frame 17, that is, at a position facing the threaded part 13 of the fixing member 12 when the shoji 2 is turned over and the bar member 5 is released from the lock member 16 and held horizontally on the indoor side.

The fixed receiving member 7 has a vertical frame 17 as described above.
In the case of a building with window openings, a rectangular body may be used, but if there is no vertical frame, it is similar to the arm 8 of the rod-shaped member 5, but slightly longer, as shown in FIG. It is composed of an elongated fixed receiving member 18 having an arm 19. One end of the arm 19 is provided with a threaded groove into which the threaded portion 13 of the fixing member 12 is screwed, and the other end of the arm 19 is rotatably supported by a frame-side mounting plate 20. This frame side mounting plate 20
A U-shaped bent part 22 protruding from the flat plate mounting part is formed on one side of the shaft support 21 on the same side as the arm 19, and the arm 19 is connected to the frame side mounting plate 20.
When the arm 19 rotates about the shaft support 21, it comes into contact with the bent portion 22, thereby preventing the arm 19 from further rotating (in the direction of the arrow A in FIG. 7).

Most importantly, the arm 19 can freely rotate in the opposite direction to the arrow direction A, and therefore overlaps the frame-side mounting plate 20.

As shown in FIG. 8, this fixing receiving member 18 fixes the frame-side mounting plate 20, which is to be used as a substitute for the vertical frame 17, to the window frame 6, and normally hangs down along the window frame. It is placed between the opposing surfaces of the frame 6 and the shoji 3. Note that this hanging fixed receiving member 18
Similarly to the rod-shaped member 5, it is also fixed by suction using a locking member made of a magnet.

To explain the effect of the above configuration, the rod-shaped member 5
The shoji 2 is rotated and reversed while being suctioned and fixed by the locking member 16. At this time, the rod-shaped member 5
Since it does not rotate freely, it does not interfere with its rotation in the same way as the fixed receiving member 7 fixed to the vertical frame 17 or the fixed receiving member 18 hanging down along the vertical frame 6. Then, the rod member 5 is released from the locking member 16 and rotated to the horizontal position as shown in FIG. At this time, the shaft hole 15 of the mounting plate 10 has a clearance, so it can be removed from the groove in an inclined state, and the arm 8 can be easily removed even if it is firmly screwed. The shaft support with the mounting plate 10 will not be destroyed due to the inclined separation. Further, since the screw portion 13 of the fixing member 12 is recessed by the coil spring 14, it does not interfere with the rotation of the shoji 2.

In addition, in the case where there is no vertical frame, the hanging fixing member 18 is rotated toward the indoor side and moved to a horizontal position, and the fixing member 12 is screwed in the same manner to couple the two. The main parts of this combined state are shown in FIG. Since the other end of the rotation of the arm 19 is regulated by the bent portion 22 of the frame-side mounting plate 20, the backward rotation of the shoji 2 is prevented after the connection.

In addition, when the shoji 2 is rotated back, the screws are released and the rod-like member 5 is tilted to return to the groove, but at this time the fixing member 12 automatically retracts its threaded portion 13 by the coil spring 14. The threaded portion 13 does not protrude from the groove 2b, and the rotation of the shoji 2 is not hindered.

As described above, this invention consists of a rod-shaped member whose one end is rotatably supported on the surface facing the window frame of a shoji stile and a fixing member is provided at the other end, and a window opening on the indoor side of a window frame or building. and a fixing receiving member that is provided in the shoji section and fixes the fixing member of the rod-shaped member when the shoji is inverted, so that the inverted shoji can be securely fixed by connecting both members. It will not be thrown away even by the force of someone else, and the work can be done safely.
In addition, since the rod-shaped member is rotatably supported on the shoji, it is easy to handle and can be used immediately when needed, and it is stored in the shoji frame when not in use, so it does not look unsightly and does not particularly interfere with the opening and closing operation. It has practical effects such as not causing any damage.
