Description

[Detailed explanation of the idea] The present invention relates to a hanging window.

Traditionally, a large amount of force was required to open and close a vertical window.

Also, if the windows were long from top to bottom, the back of the room could not be reached, making opening and closing the upper door extremely troublesome.

The purpose of the present invention is to solve these problems, and to enable both the upper and lower doors to be raised and lowered easily and smoothly, and also to allow the lower door at the lower position to be raised and lowered at the same time to open and close the upper door at the higher position. The feature of the hanging window of the present invention is that it has three upper doors, a middle door and a lower door, and at least the upper door and the lower door are attached to the vertical window frame so as to be able to move up and down to form a single hanging window. A pair of rotors are pivotally mounted near the upper and lower ends of the side edges of the intermediate door or above and below the vertical frame of the window, and between the rotors there is provided a belt, rope, chain, etc. that can be freely extended or bent. The transmission members are engaged from the side in an endless elliptical shape, and a part of the side edges of the upper door and the lower door are fixed to two corresponding sides of the elliptical shape using fixing tools.

Hereinafter, the present invention will be explained in detail based on the illustrated embodiments.

Figures 1 and 2 are in the closed state, Figure 3 is in the middle of opening and closing, and Figure 4 is in the closed state.
The figure shows an embodiment of the present invention in an open state, and 1 is an upper door, 2 is an intermediate door, and 3 is a lower door. These three doors 1, 2.degree. 3 are attached to the peripheral frame member 6 which has been formed to form a single vertical window.

Specifically, as shown in Fig. 7, the intermediate door 2 is pivotally supported on the vertical frames 4, 4 by support shafts 1, 7, and does not move up and down, but can swing freely as shown by arrow M in Fig. 2. installed.

On the other hand, the upper door 1 and the lower door 3 are attached to the vertical frames 4, 4 so as to be vertically movable, and in FIG. 6, the side edges 9, 9° 10. 1G is installed.

Although not shown, it is also possible to provide rails protruding from the vertical frame 4 to guide the side edges 9, 9 or 10, 10.

As shown in FIGS. 1 to 7, a pair of rotors 11.1, such as pulleys, are installed at a predetermined distance above and below the vertical frame 4.
1 is rotatably pivoted with a support shaft 12.12, and between the rotors 11 and 11, a transmission member 13 such as a rope or wire that can be freely deformed in extension and curvature is shaped into an endless vertically elliptical shape when viewed from the side. The top and bottom are interlocked.

That is, as is clear from the perspective view of FIG. 5, the transmission member 13 is suspended, and fasteners 14.15 are attached at approximately symmetrical positions, and the fasteners 14.15 are attached to the upper door 1 and the lower door 3, respectively.
The respective side edges 9 and 10 of the transmission member 13 are fixed to the transmission member 13 in a connected manner.

In the specific example shown in FIG.
Fixing tools 14 and 14 are attached as left and right protrusions from 9,
It is operatively connected to a transmission member 13.13 via this fastener 14.14.

Further, fixing members 15.15 are attached as left and right protrusions from the side edges 10, 10 of the lower door 3, and are interlocked and connected to the transmission member 13.13 via the fixing members 15.15.

Note that the rotor 11 and the transmission member 13 are built inside the vertical frame 4 that is hidden from the frame so that they cannot be seen from the outside, and are inserted through a groove 8 on the inner surface of the vertical frame 4 in a predetermined range above and below. The fixing tools 14 and 15 are inserted into the vertically elongated holes 16 and moved up and down.

Therefore, when the lower door 3 is raised as shown by arrow F, the upper door 1 is opened downward as shown by arrow G.

Also, if lower door 3 is lowered, upper door 1 will be raised. The distance it moves is the same, and it always opens and closes in the upside down direction.

In the specific example shown in FIG. 2, if the intermediate door 2 is swung as shown by the imaginary line, the outdoor surface of the upper door 1 or the lower door 3 can be cleaned by hand from inside the room, which is very preferable.

Although not shown, it is of course possible to fix the intermediate door 2 to the vertical frame 4 using a different structure, and in some cases, the intermediate door 2 can also be attached independently so as to be movable up and down. .

Therefore, FIGS. 8 to 13 are different embodiments, and FIGS.
The figure shows the closed state, Fig. 9 shows the state in the middle of opening and closing, Fig. 10 shows the open state, and Figs. 11 and 12 show the case where all three doors 1, 2, and 3 are moved downward in special cases. The biggest difference from the previous embodiment is that rotors 11 and 11 are pivotally mounted near the upper and lower ends of the side edge 17 of the intermediate door 2.

Further, the rotor 11 is exemplified as a chain wheel, and the transmission member 13 suspended thereon is a chain.

That is, during normal use, as shown in FIGS. 8, 9, and 10, the intermediate door 2 is attached to the vertical frame 4 by a fixing/releasing mechanism (not shown).
Only the upper door 1 and the lower door 3 can be opened in conjunction with each other as shown by arrows F and G, or can be closed in conjunction with each other in the opposite direction to the arrows.

FIG. 13 shows a more specific structure, in which the rotor 11 is pivotally connected to the side edge 17 of the intermediate door 2 by a support shaft 12, and is housed inside the vertical frame 4 together with the transmission member 13 and is not visible from the outside. ,
The transmission member 13 and the upper door 1 or the lower door 3 are connected by fixing members 14 and 15.

Similarly, a vertically elongated hole 16 is provided through the groove 8.

The normal fully open state is as shown in Fig. 10, but if you particularly want to move the three doors 1, 2, and 3 in their entirety downward, the lower door 3 is fixed to the surrounding frame member 6, and the middle door is moved downward. Release the above-mentioned fixation/release mechanism of the door 2, and move the intermediate door 2 at a predetermined speed in the direction of arrow H.
If the upper door 1 is lowered in the direction indicated by the arrow, the upper door 1 will descend at twice the speed as shown in the arrow, and the state shown in FIG. 12 can be achieved.

This is preferable for loading and unloading large items. The present invention is not limited to the above-mentioned embodiments, and design changes may be made freely.
For example, a belt may be used as the transmission member 13, and the rotor 11.
It is also preferable to use a belt pulley as the rotor 11, or if the width of the window is narrow, the rotor 11.11 and the transmission member 13.
It is also free to provide it only on either the left or right side.

Furthermore, the lift/lower window of the present invention is not limited to residential use, but can also be freely applied to windows of trains, etc.

At that time, it is possible to open and close the lower door 3 using the upper door 1, and it is preferable because the upper door 1 and the lower door 3 can always be balanced without using any balance weights.

As detailed above, the present invention has a simple structure, is easy to assemble, has few causes of failure, and also maintains balance between the upper door 1 and the lower door 3 at all times without using any balance weights.
Light and smooth opening/closing operation was achieved.

In particular, even if the window is tall vertically, if only the lower door 3 is moved up and down by hand, the upper door 1 at a higher location will open and close in conjunction with each other, making opening and closing operations simple and extremely effective from the point of view of indoor ventilation. Efficient.

Furthermore, even on walls where it is impossible to install a casement window due to space limitations, the hinged window of the present invention can be installed since it does not require any space when opening and closing, which is very convenient in terms of ventilation.
