Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a safety tool for cleaning a reversible revolving window, particularly a revolving window equipped with a shoji opening maintaining device.

A reversible horizontal axis rotating window equipped with a shoji opening maintaining device 1 as shown in FIGS. 1A, 1B, and 1C is well known.
In order to clean the outdoor side of the window glass in this revolving window, the shoji 2 is flipped 180 degrees and cleaning is performed on the indoor side. However, since it has a structure that cannot be locked when it is turned upside down, it is necessary to support it so that it does not rotate.However, in the case of a rotating window with a large area, it is not possible for a worker to support the shoji 2 while cleaning it alone. Unable to do so, one person was supporting the building while the other was cleaning, which was an inefficient task. Furthermore, if the worker is working alone, the window will swing due to the force applied by the worker, making it very difficult to clean, especially when cleaning the area above the rotating shaft 3. As shown in Figure 2, the momentum caused the shoji 2 to turn from the position shown by the solid line to 2', 2'' shown by the imaginary line, and the person was tripped and remained there. In some cases, the machine fell outside, leading to a great tragedy.For this reason, in the past, safety belts were fixed somewhere inside the room to ensure safety when working alone. Fixing work is complicated and unreliable, so improvements have been desired.

This idea was made based on the above request, and a safety device that holds the rotating window shoji when it is reversed is removably attached to the mounting base on the window frame side of the opening maintenance device, thereby improving work safety. To provide a safety tool for window cleaning which can be used when necessary without requiring complicated operations, and can be removed and put away when not in use.

This invention will be explained in detail below with reference to FIGS. 1 to 9.

In FIG. 3, reference numeral 4 denotes a safety device according to this invention, and the upper stile 2a of the shoji 2, which has been reversed by releasing the link connection of the shoji opening maintaining tool 1, is clamped and fixed by the safety device 4.

The safety device 4 has a safety device main body 5 and a clamping member 6 as its main components, and the safety device main body 5 is attached to the shoji opening maintenance device 1 and arranged on a tray board on the indoor side.

First, the shoji opening maintenance tool 1, which is a prerequisite component of the present invention, will be explained.

As shown in FIGS. 4 to 6, the shoji opening maintenance tool 1 has a window frame side mounting base 7 and a shoji side mounting base 8.
and first and second arms 9 and 10.

The shoji side mounting base 8 is screwed to approximately the center of the shoji lower stile 2b so as to protrude toward the indoor side, and one end of the first arm 9 is attached to the protrusion by a pivot 12 supported by a coil spring 11. is pivoted by
When the pivot 12 is pushed against the elastic force of the coil spring 11, the pivot coupling is released. The other end of the first arm 9 is pivotally supported by one end of a flat arcuate second arm 10.
The other end of the window frame 13 is in contact with a substantially central position of the window lower frame 13, and is pivotally supported by a window frame side mounting base 7 screwed to the tray plate 14. This window frame side mounting base 7 is the 9th
As shown in the figure, a vertical groove 16 is formed in the central convex portion 15, in which the second arm 10 is rotatably supported, and the screw fixing portion 17 is attached to the central convex portion 15. It is provided on both sides of the The imaginary line in FIG. 4 shows a state in which the above-mentioned shoji opening maintaining device 1 is extended and the shoji 2 is half-opened.

Next, to explain this idea, Figures 7 to 9
The figure shows an embodiment of the safety equipment.The safety equipment main body 5 is a plate-shaped body disposed on the tray plate 14 at a substantially right angle to the window lower frame 13, and the length is the same as that of the upper stile of the shoji. The width and thickness of the window frame side mounting base 7 is longer than the width and thickness of the shoji upper stile 2a so as to be able to receive the shoji upper stile 2a, and the thickness is such that it does not hinder the inverted shoji upper stile 2a from coming onto the safety equipment main body. It is formed to have the same thickness as the screw fixing part 17. At one end in the longitudinal direction of this safety device main body 5, there is a vertically divided groove that rises at approximately the thickness of the plate and projects in the longitudinal direction, and into which the central protrusion 15 of the window frame side mounting base 7 is fitted. 18, and a pin 20 that is attached to a horizontal hole passing through the double head 19 so as to be retractable from both sides in the vertical groove 18, Locking means 22 are provided which consist of a pin 20 which is retracted from the longitudinal groove 18 by pulling against it. On the other hand, at the other end in the longitudinal direction of the safety device main body 5, a raised part 23 is formed on both sides thereof with a height that does not inhibit the reversal of the shoji. A long hole 24 through which the pivot shaft is inserted is provided horizontally, and pivot means 25 is provided that allows the pivot shaft to slide in the longitudinal direction of the safety device main body 5.

The clamping member 6 is a substantially L-shaped member having a width that can be inserted between the protrusions 23 of the safety device main body 5, and a pivot 26 is provided at one end of the clamping member 6, which extends through the elongated hole 24. It is rotatable, and a long hole 28 extending in the longitudinal direction of the safety device main body 5 is penetrated in the thickness direction approximately at the center of the horizontal portion 27 on one end side. It is desirable that the rising portion 29 extending from the horizontal portion 27 be inclined somewhat more than at a right angle. That is, when the clamping material 6 is stood up and placed on the safety device main body, the door stop 30 protruding from one side of the inverted shoji upper stile 2a (the surface facing the outdoor side when inverted) is attached to the window frame side. The center convex portion 15 of the base 7 or the angle of inclination of the other side of the shoji upper stile 2a (the surface facing indoors) at the position where it abuts against the double head 19 of the safety equipment body 5 is adjusted. Furthermore, a cushion material 31 is attached to the side of the shoji that comes into contact with the upper stile 2a.

Numeral 32 is a bolt for fixing the upright clamping member 6 to the safety equipment main body 5, and the bolt 33 has a larger diameter than the elongated hole 28.
By screwing into a screw hole 34 provided in the safety device main body 5, the upright portion 29 is held at the above-mentioned inclination angle.

The operation of the above structure will be explained below. When cleaning the outdoor side surface of a shoji, a worker wears safety gear before turning the shoji over. Its attachment is done using pins 20, 20 attached to the double head 19 of the safety equipment body 5.
, the central convex part 15 of the window frame side mounting base 7 is held in the vertical groove 18, and the pin 20 is inserted into the central convex part 1.
This is done by releasing the locking holes 35 provided on both sides of the locking hole 5 when the locking holes 35 are aligned with each other. As mentioned above, since the pin 20 is resiliently supported by the coil spring 21, this locking is reliable and will not come off. In addition, the double head 19 rises and protrudes from the safety device main body 5, and the screw fastening portion 17 of the window frame side mounting base 7 enters into the space formed by the rise, and the safety device main body 5 is placed on the tray board. As a result, rotation of the other end of the extended safety equipment main body 5 is restricted, and the safety equipment main body is completely fixed. The reason why this attachment can be performed while the opening maintenance device 1 is retracted before inversion is because the second arm 10 is flat as shown in FIG. This is because it can be slipped under the open maintaining device.

In addition, in this embodiment, the window frame side mounting base 7 is fixed to the lower frame indoor side window opening plate 14, but if there is no plate plate, it may be fixed to the window frame, and in this case, the window frame side mounting base 7 The screw fastening part 17 is not necessarily required as a screw fastening part as in the embodiment, but
As described above, it is necessary to prevent rotation of the safety equipment main body 5. In this case, it is of course possible to use other configurations as means for preventing rotation of the safety device main body 5.

The bolts 32 of the clamping member 6 are removed, and the clamping member 6 is laid down on the tray board so as to be outside the rotation locus of the shoji screen, as shown by the imaginary line in FIG. Next, the link connection of the shoji retainer 1 is released, the first and second arms are extended to the outside, the shoji 2 is turned over, and the doorstop 30 is attached to the central protrusion 15 of the window frame side mounting base 7. Contact stops.

Therefore, the abutment surface of the central convex portion 15 is formed to be inclined so as to make surface contact with the door stop 30 in order to make smooth abutment with the door stop 30. In addition, the double head 1 of the safety equipment body 5
It may be arranged so that it comes into contact with 9. Also doorstop 30
may be attached to the window frame side mounting base 7 or the safety equipment main body 5 side.

The clamping member 6 is rotated in the direction in which it overlaps the safety device main body 5 as shown by the solid line in FIG. 7, and is raised to bring the cushion member 31 of the rising portion 29 into contact with the shoji upper stile 2a. The clamping member 6 has a pivot 26 that is connected to the elongated hole 2.
4, it can slide in the longitudinal direction of the safety device main body 5, and the abutment can be brought into close contact. This sliding adjustment is done by attaching the upper stile of the shoji to the window frame mounting base 7.
This is particularly effective for securely clamping between the clamping member 6 and the clamping member 6. The bolts 32 for fixing the clamping member 6 to the safety device main body 5 can be tightened by sliding the bolts 32 through the screw holes 3 because the bolt holes in the clamping member 6 are long holes 28.
Can compensate for positional deviation from 4, and bolt 32
Since it is provided with a tsuba 33, it can be done reliably without being immersed.

In this way, clamping and fixing of the reversible shoji can be accomplished through a simple three-step operation of rotating the clamping member, sliding it, and tightening the bolts.

To open the inverted shoji, perform the operation in reverse to the above, but after removing the safety device, if the clamping material 6 is tightened with the bolt 32, the clamping material will not rotate freely, making it convenient to carry. Danger can be prevented, and there is no need to take up space when storing it in a warehouse or the like.

As mentioned above, according to this invention, the safety device is removably attached to the window frame side mounting base, so the window frame side mounting base not only functions as the mounting base for the shoji opening maintenance tool. Since it also serves as the mounting base for the safety equipment, the mounting base can be used effectively. Furthermore, since the safety gear is removable, it can be removed normally and attached only when necessary, making it easy to handle. Furthermore, since the shoji is clamped by rotating the clamping material, it does not become an obstacle when the shoji is turned over, and if the clamping material is fixed, the shoji can be reliably locked.

In this way, the window cleaning safety device of this invention can safely and reliably clean the window glass on the outside surface of the shoji indoors.
Moreover, it has various remarkable effects such as being able to do the work alone.
