Description

[Detailed description of the invention] This invention relates to an elevating window that opens and closes the window using two upper and lower window shoji with screen screens.The purpose of this invention is to enable easy and smooth opening and closing operations. To provide an elevating window whose screen door can be freely opened and closed.

An embodiment of the present invention will be described below in detail with reference to the drawings.

Figure 1 shows a schematic diagram of the elevating window seen from the outside of the room.
Two upper and lower shojis 1 and 2, each having the same size, are attached to the window frame 3 so that they can move up and down in conjunction with each other. The screen doors 4 and 5 are connected to each other, and as the upper shoji 1 and the lower shoji 2 move relative to each other downward and upward together with the screens 4 and 5 from the fully closed position shown in this figure, the upper part of the window portion changes. The upper and lower portions are gradually opened, and when both the shoji 1 and 2 completely overlap, the fully open position is reached, and in this fully open position, the open portion of the window is fully closed by the screens 4 and 5.

The detailed structure of this elevating window will be explained according to FIG. The lower shoji 2 is made by inserting a glass plate 15 into a window inner frame 14 consisting of left and right vertical frames 11.11 and upper and lower horizontal frames 12.13. , this upper shoji 1 is fitted into the outdoor side rail grooves 17.17 of the left and right side frames 16.16 constituting the window outer frame 3, and the lower shoji 2 is fitted into the indoor side rail grooves 17.17 of the same side frames 16.16, It is inserted into 18.

Each vertical stile 6 of the window inner frame 9 and each vertical stile 11 of the window inner frame 14
Shapes 19 and 20 having racks 19a and 20a are respectively mounted and fixed at positions facing each other, and each side frame 16 of the window frame 3 has a rack 19a of the mold 19 and a rack 20a of the mold 20. A pinion gear 21 that meshes with is pivotally supported at an intermediate position between the outdoor rail groove 17 and the indoor rail groove 18.
Each of the vertical frames 11 of No. 4 is provided with guide bushes 24 at a plurality of locations, each slidingly contacting the inner surface of the outer wall 22 of the indoor rail groove 17 and the inner surface of the outer wall 23 of the indoor rail groove 18. Pinion gear 21 has rail groove 17.1
8, but since a partition wall 25 that partitions both rail grooves 17 and 18 is extended at this position, the part where the pinion gear 21 is arranged is not shown in the figure, but the part of the partition wall 25 is Part of it is removed.

Further, this pinion gear 21 is connected to the rail groove 17.1.
It is desirable to arrange a plurality of them at required intervals along 8.

As shown in FIG. 4, the screen doors 4 and 5 have the respective lengths l of the upper shoji 1 and lower shoji 2, and the lower end of the window frame 9 of the upper shoji 1 and the inside of the window of the lower shoji 2. They are each attached and fixed to the upper end of the frame 14.

FIG. 4A shows the window in the fully closed position. When the upper shoji 1 is pulled downward from this fully closed position, the pinion gear 21 is rotated counterclockwise by the rack 19a, and the rotation of the pinion gear 21 is is transmitted to the rack 20a and pulls the lower shoji 2 upward, the upper and lower parts of the window part are gradually opened symmetrically, and the upper shoji 1 and the lower shoji 2 are completely opened as shown in the opening of Figure 4. When they overlap, the windows are opened to the maximum extent and are in the open position.

In this fully open position, the lower open portion 26 and upper open portion 27 of the window are closed by the screens 4 and 5.

Figure 4C shows the intermediate position between the fully closed position in Figure 4A and the fully closed position of the opening in Figure 4, where the lower end of the screen door 4 on the upper shoji 1 side matches the lower end of the lower shoji 2. , the upper end of the screen door 5 on the lower shoji 2 side matches the upper end of the upper shoji 1, and both shojis 1 and 2 and the screen door 4°5 are completely overlapped, and in this state, the upper and lower parts of the window part The maximum throughput is in part 2
8.29 will be possible.

In addition, in the above explanation, the lower shoji 2 is raised at the same time by pulling down the upper shoji 1, but the same effect can be achieved even if the upper shoji 1 is lowered by pulling up the lower shoji 2. However, in this embodiment, the upper shoji 1 is located on the outside, so the former is convenient for operating from the outside, while the latter is convenient for operating from the inside.

To attach the screen doors 4, 5 to the upper shoji 1 and lower shoji 2, for example, locking tools 30 as shown in FIG. On the other hand, a locking device insertion hole 32 as shown in the figure is opened in the upper surface of the upper stile 31a that constitutes the frame of the screen door 4 at a position slightly offset from the position corresponding to the locking device 30. , Lift the screen door 4 vertically below the upper sash 1 and insert the locking tool 30 into the insertion hole 32, then move the screen door 4 slightly laterally and lock the locking tool 30 inside the upper stile 31a. All you have to do is let it happen.

A similar method may be used when attaching the screen door 5 to the lower shoji 2.

In addition, since the screen doors 4 and 5 are likely to shake if only the above-mentioned locking tool 30 is used, the outer surface of each side frame 31b of the screen doors 4 and 5 is attached to the outer surface of each side frame 31b (FIG. 6).

A screen door holding piece 33 having a substantially trapezoidal shape as shown in FIG.
It is kept in a state where it is fitted in the side frame 16 of.

In this embodiment, the screen door is detachable from the shoji screen, but the screen door may be attached integrally to the shoji screen.

In FIG. 3, reference numeral 37 designates the window outer frame 3, and an upper frame 38 indicates the lower frame of the window outer frame 3.

As explained above, the elevating window of the present invention has a screen door with a length approximately % of the length of the shoji connected to the lower part of the upper shoji and the upper part of the lower shoji, so that the upper shoji and the lower shoji overlap and the volume is increased. In the open position, the upper open part and the lower open part of the window are respectively blocked by the screen door, and can play a sufficient role as a screen door, and in the intermediate position between the fully open position and the fully closed position, the upper open part and the lower open part of the window part are closed by the screen door. There is a through hole at the bottom that is not blocked by the screen door, so if you are bringing a flower box placed on a balcony or the like indoors, or if you want to take it outside while indoors, this through hole is also necessary. It has the advantage of being able to be freely put in and taken out using the .

In addition, the elevating window of the present invention is provided with rack members facing each other in the vertical stile that constitutes the window inner frame of the upper shoji and the corresponding vertical stile of the lower shoji, and a pinion that meshes with both rack members. is pivoted to the side frame of the window frame, and the upper and lower shoji are interlocked, so that the window can be opened and closed by the relative vertical movement of both shoji. The gravity of the shoji on the descending side can be used and the weight of both shojis can be balanced, making it possible to open and close the window smoothly and safely with relatively little force. Since the upper and lower parts of the window can be opened at the same time, when the window is opened and closed, warm indoor air is exhausted from the upper part, and cooler outside air enters the room from the lower part, causing convection inside the room. promote,
It has the particular advantage of allowing effective ventilation.
