Description

[Detailed Description of the Invention] This invention relates to an improvement in a so-called lift-and-lower window that allows the interior of the window frame to be raised and lowered freely.

Conventional sliding windows of this type can only be moved up and down, so even though they provide ventilation, it is difficult to clean the sliding shoji. In other words, when cleaning both indoor and outdoor glass shojis, cleaning the interior surfaces of both glass shojis is not much of a problem (although if the upper glass shoji is tall, cleaning the upper part of the interior surface is troublesome). ), when the upper glass shoji of both the upper and lower glass shoji is fixed and only the lower glass shoji can be raised and lowered, as in the object field of this invention, the entire exterior surface of the glass shoji is It was completely impossible to clean it from the inside.

This idea focuses on the above-mentioned difficulties, and allows the upper shoji, which is fixed in a fixed position, to be tilted toward the indoor side at that position, and the lower shoji, which is moved up and down, to be tilted toward the indoor side. This makes it easy to clean both the indoor and outdoor surfaces of both shoji screens from the indoor side.

Figure 1 shows an example of this invention.
This figure shows the appearance of the vertical window as seen from the inside of the room. That is, an upper shoji 2 located on the outside side of the window and a lower shoji 3 located on the indoor side are fitted into the window frame 1. Of these, the upper shoji 2 is installed in a fixed position in the closed state, and the lower shoji 3 is attached to the window frame 1. The frame 1 can be moved up and down freely between the vertical frames 4, 4, and counter balancer mechanisms 5, 5 such as tension springs and air cylinders are attached to both the vertical frames 4, 4. By connecting the balancer mechanism 5 to the lower shoji 3, the lower shoji 3 can be stopped at any vertical position.

Furthermore, the lower shoji 3 can not only be moved up and down as shown in FIG. Moreover, as shown in FIG. 2c, the upper shoji 2 can also be tilted toward the interior of the room around a support shaft 7.

Figures 3 and 4 are lines AA and B in Figure 1.
In the cross-sectional view taken along the line -B, the upper shoji 2 normally has a locking rod 8a of a locking mechanism 8 attached to the upper stile 2a engaged with the upper frame 9 of the window frame 1, and both vertical frames 2 of the upper shoji 2.
The above-mentioned pivot shafts 7 for rotation, which are fixed to b and project from both sides of the shoji, are fixedly attached by engaging with the vertical frame 4 of the window frame 1, while the lower shoji 3
is a guide pin 1 protruding from both sides of the upper stile 3a.
0 and the pivot shaft 6 for rotation protruding from both sides of its lower stile 3b
enters a guide groove 11 formed in the vertical frame 4, and is guided by these guide members so that it can freely move up and down between the vertical frames 4. It is necessary to ensure sufficient watertightness when closing this type of lift-down window, and for this reason, in this embodiment, in order to ensure a seal between each horizontal frame, as shown in Fig. 3, As shown, the upper stile 2a of the upper shoji 2
A sealing member 12a such as a moket or packing is placed between the upper frame 9 of the window frame 1 and the lower frame 2 of the upper shoji 2.
sealing members 12b and 12c that contact each other between the upper stile 3a of the lower shoji 3 and the lower stile 3b of the lower shoji 3 and the lower frame 13 of the window frame 1.
2d, and in order to ensure a seal between each vertical frame, window frame vertical frames 4 are installed only in both vertical frames 2b of the upper shoji 2 and the area defined by these vertical frames 2b, as shown in FIG. Water cutter 14 protruding from the outside of the room (right side in Figure 4)
In addition, a sealing member 12e is provided between both vertical frames 3c of the lower shoji 3 and a water cutter 15 protruding from the center of the window frame vertical frame 4 only in the area facing the vertical frame 3c (left side in FIG. 4). A sealing member 12f is interposed between the two.

Figures 5a and 5b are enlarged detailed views of part C in Figure 1, showing guide pins 1 provided on the upper stile 3a of the lower shoji 3.
0 shows the appearance and appearance structure.

That is, the guide pin 10 is fitted into a guide cylinder 16 fixed inside the upper stile 3a, is urged by a compression spring 17, and normally projects into the vertical frame guide groove 11.
This allows for free vertical movement, and a guide shoe 18 is appropriately attached to the guide pin 10 in order to eliminate wobbling during movement. When the lower shoji 3 is tilted, the knob 19 is naturally moved to the right side in the figure to allow the guide pin 10 to escape from the guide groove 11.

Figures 6a and 6b are enlarged detailed views of portion D in Figure 1, in which a counterbalancer mechanism 5 that utilizes the tensile force of a tension spring and the air resistance of an air cylinder is installed in the guide groove 11 of the window frame vertical frame 4. Its upper end is attached to the upper end of the vertical frame 4, and its lower end is attached to the sixth
As shown in FIG. The shoji 3 is guided by a slide shoe 20 sliding in a guide groove 11 to move up and down, and can also be tilted toward the indoor side around a support shaft 6 supported by the slide shoe 20.

As described above, according to this invention, in a lift-down window that consists of an upper shoji and a lower shoji, of which only the lower shoji can be raised and lowered, the upper shoji is placed on the outside of the room, and the lower shoji is placed on the inside of the room. Rotating support shafts are provided protruding from the lower ends of the upper and lower shoji or on both sides near the lower ends, and the upper and lower shoji are formed so that they can be tilted toward the indoor side around the rotation support shafts. Therefore, it is possible to easily clean the outdoor surface of the indoor lower shoji, which was previously impossible, and both the indoor and outdoor surfaces of the tall outdoor upper shoji, which were difficult to clean, from the indoor side.

Moreover, according to this proposal, the rotation support shaft protruding from the lower shoji is attached at one end to the other end of the counter balancer mechanism attached to the upper end of the vertical frame, and is rotated by the balancer mechanism. Since the upper shoji is formed so that it can be stopped at any raised or lowered position, the degree of opening of the lower shoji for ventilation etc. can be freely adjusted.

Furthermore, according to the embodiment of this invention, a watertight sealing member is interposed between the opposing surfaces of the upper and lower shoji in the closed state and between the window frame and the opposing surfaces of the upper and lower shoji, respectively. It is possible to reliably improve the watertight effect, which is the most important effect in this type of hanging window.
