Description

[Detailed Description of the Invention] This invention relates to a window sash that can be easily cleaned by inverting the inside and outside surfaces of the shoji.

As is well known, window sash shoji installed on the outdoor side of buildings must be cleaned when they become dirty. Although the inner surface of the sash on the indoor side can be easily cleaned, it is difficult to clean the outside surface of the sash on the outdoor side. When cleaning, people would either remove the shoji and clean it, lean forward from the inside to the outside to clean, or hang a gondola from the roof to the outside of the satsushi and clean from inside the gondola. However, it is structurally impossible to remove the shoji from the indoor side, and it is extremely dangerous to lean out from the indoor side to the outdoor side to clean it, and moreover, you can only clean within your reach. Furthermore, in order to clean with a gondola, an expensive gondola moving lifting device must be installed on the rooftop, which cannot be installed in buildings with a small number of floors, and since the gondola is suspended from the rooftop, it is susceptible to wind pressure and It swayed during cleaning, making it difficult to work.

Therefore, this invention is devised so that the inside and outside surfaces of the shoji can be turned over indoors without removing it from the sash frame, so that the inside and outside surfaces of the shoji can be cleaned indoors.

Below, the structure of the proposed sash will be explained with reference to drawings of examples. A is a sash frame that is attached to an opening in a building, and the sash frame A is composed of a vertical frame 1 and upper and lower frames 2 and 3, which are extruded from a light metal material. , on the indoor side of the vertical frame 1 and the upper and lower frames 2 and 3, there are inner walls 1a, respectively.

31, and a tight material T is fitted into the fitting grooves 11, 21, 31, parallel to the longitudinal direction of the lower frame 3, at the center of the lower frame dish wall 3c which is inclined downwardly toward the outdoor side. A rail 32 and a projecting strip 33 are provided on the outdoor side thereof, and two hanging pieces 2d and 2e are provided in the middle part of the upper frame side wall 2c parallel to the inner wall 2a, and the hanging piece 2d,
A groove 22 facing the lower frame rail 32 is formed between 2e, and a groove 12 for fitting the waterproof piece R is formed in the outer wall 2b of the upper frame 2.
is formed. B is a shoji that is inserted into the sash frame A, and the shoji B is a shoji frame C that is made up of a hollow vertical frame 4 extruded from a light metal material and upper and lower frames 5 and 6, and a glass G is fitted therein. A glass fitting part 41 is provided on the inner circumference side of the vertical frame 4, the outer circumference is formed into a semicircular arc wall 4b, and a fitting groove 42 that opens toward the outer circumference is provided at the entire height of the top of the arc wall 4b. The airtight piece S is fitted into the groove 42, and the outer walls 5b, 6 of the upper and lower frames 5, 6 are closed.
b protrudes toward the outer circumference to such an extent that it does not come into contact with the outer walls 1b, 2b, and 3b of the sash frame A. E is an upper metal fitting that is attached to the upper end of either the left or right vertical frame 4 that constitutes the shoji B, and the upper metal fitting E is the hollow part 4 of the vertical frame 4.
A main body 17 that is inserted into and fixed in the main body 17, a retractable height adjustment bolt 27 that is screwed into the main body 17, and a height adjustment bolt 27 that is attached to the upper part of the adjustment bolt 27 and inserted into the groove 22 of the upper frame 2, It consists of a head 7 that rotates horizontally on the extension of the center line of the wall 4b, and a spring 7 is attached to the head 7.

is pressed in the outdoor direction by the projecting/retracting piece 7b. F is a lower metal fitting that is attached to the lower end of the vertical stile 4 to which the upper metal fitting E is attached. The door roller 8 is composed of an outer box 8a that can be rotated horizontally on the extension of the center line of the arcuate wall 4b, and an inner box that can be inserted into the outer box 8a and tilted indoors and outdoors. 8b, and a groove wheel 8c that is pivotally supported in the inner box 8b, and when the groove wheel 8c runs along the lower frame rail 32 and draws the shoji B toward the indoor side, the pivot position of the door roller 8 is The lower frame rail 32 is moved toward the indoor side from the formation position, and the inner box 8b is tilted by that amount as shown in FIG. The sash frame A is drawn toward the indoor side and comes into contact with the tight material T, and the airtight pieces S provided on the arcuate walls 4b of the left and right vertical frames 4A, 4B contact the vertical frames 1, 1'. Upper and lower fittings E,
Since the vertical stile 4 to which F is attached runs along the groove 22 of the upper frame 2 and the lower frame rail 32, this will be referred to as a sliding vertical stile 4A from now on, and the vertical stile 4 to which the upper and lower fittings E and F are not attached is as follows. It is possible to go in and out of the outdoor side from the sash frame A around the head 7 of the upper bracket E, which rotates horizontally at the center of the swinging vertical stile arc wall 4b, that is, on an extension of the center line, and the adjustable door wheel 8 of the lower bracket F. Therefore, this will be referred to as the free vertical frame 4B from now on. Reference numeral 9 denotes a swinging rod that is pivotally supported between the outdoor side of the sash frame A and the middle part of the shoji frame C. Specifically, it is located closer to one vertical frame 1 on the outdoor side than the upper frame hanging piece 2d and the lower frame protrusion 33. , the support 19 is located near the left vertical frame 1' in the drawing.
, one end of the swinging rod 9 is pivotally supported on the support body 19, and the swinging rod 9 can be pivoted using the pivot support as a fixed fulcrum _P1 . It is pivotably supported via W, and the pivot is used as a movable fulcrum _P2 .

Since the proposed sash has the above structure, the sash frame A is constructed in advance by the vertical frames 1, 1' and the upper and lower frames 2, 3, and the sash frame C is constructed by the vertical frames 4A, 4B and the upper and lower frames 5, 6. The main body 17 of the upper metal fitting E is inserted and fixed into the hollow part 4a from the upper part of one of the left and right vertical frames 4A, 4B forming the shoji B, and the upper metal fitting E is inserted and fixed.
After protruding the head 7 above the upper end of the stile 4,
The base body 18 of the lower metal fitting F is inserted and fixed into the hollow part 4a from the lower side of the same vertical stile 4 to form a sliding vertical stile 4A, and the other vertical stile 4 is made into a free vertical stile 4B without attaching the upper and lower fittings E and F. I'll leave it as that. Also, the upper frame 2 that constitutes the satsushi frame A
A support 19 is attached to the outdoor side of the lower frame 3 at a position close to one of the vertical frames 1', and one end of the swinging rod 9 is pivotally supported on this support 19.
Then, fit the shoji B from the outdoor side, and at that time, insert the head 7 of the upper metal fitting E attached to the sliding vertical stile 4A into the groove 22 of the upper frame 2, and insert the head 7 of the upper metal fitting E attached to the sliding vertical stile 4A into the door car inner box 8b of the lower metal fitting F. The groove wheel 8c, which is pivotally supported by the groove wheel 8c, is mounted on the lower frame rail 32 so that it can run along the groove 22 of the upper frame 2 and the lower frame rail 32, and the head 7 of the upper metal fitting E and the adjustable door wheel 8 of the lower metal fitting F are placed on the lower frame rail 32. The vertical stile 4B side is made to be able to swing in and out toward the outside around the center. Next, Satsushi upper frame 2
The flexible vertical stile 4B is pushed out to the outside of the room centering on the sliding vertical stile 4A that runs along the groove 22 and the lower frame rail 32, and the shoji B is appropriately opened like a door. One end of a swinging rod 9 is pivotally supported on the sash frame A, and the other end of the swinging rod 9 is pivotally supported at the center of the outer periphery of the
Complete the installation of shoji B. Also, shoji upper and lower frames 5 and 6
One end of the swinging rod 9 is pivotally supported at the center of the outer periphery of the
Fit the shoji B to the sash frame A from the outdoor side, and attach the head 7 of the upper bracket E attached to the sliding vertical stile 4A to the upper frame 2.
After inserting it into the groove 22 of the lower bracket F and placing the adjustable door wheel 8 of the lower bracket F on the lower frame rail 32 and making the sliding vertical stile 4A travelable, the adjustable vertical stile 4B is pushed out to the outdoor side and opened as appropriate. The other end of the swinging rod 9 that is pivotally supported on the shoji B is attached to the vertical frame 1' on the outdoor side of the sash upper frame 2 and lower frame 3.
It is pivotally supported on a support 19 installed at a position close to. After fitting the shoji B and installing the swinging rod 9, turn the adjustment bolt 27 of the upper bracket E attached to the swinging rod 4A to adjust the insertion amount of the head 7 into the groove 22 of the upper frame 2. Adjustments are made to complete the installation of shoji B.

In the above-mentioned sash, the flexible vertical stile 4B is located on the side of the fixed fulcrum P ₁ of the swinging rod 9, and the first stile B is closed.
As shown in the figure, in order to open the shoji B and reverse its inner and outer surfaces, first push out the vertical stile 4B of the shoji B toward the outside, and then a sash will be placed at the center of the outer periphery of the upper and lower sills 5 and 6. A swinging rod 9 that rotates with the frame A as a fixed fulcrum _P1 is attached, and the swinging rod 4A of the shoji B
is able to travel along the groove 22 of the upper frame 2 and the lower frame rail 32, and is also rotatable around the upper and lower fittings E and F attached to the sliding vertical stile 4A, so it resembles a parallel motion mechanism similar to a Scotstratz cell. As shown, the sliding vertical stile 4A is a sliding pair, and there is a gap between the sliding vertical stile 4A and the movable fulcrum P ₂ of the swinging rod 9, between the movable fulcrum P ₂ and the free fulcrum 4B, and between the movable fulcrum P ₂ and the fixed fulcrum. Since the distances between _{P1 and} P1 are approximately equal, as the flexible vertical stile 4B is pushed out to the outdoor side, it is linearly released from the sash frame A toward the outdoor side as shown in Fig. 7, and as the sash frame B is opened, the swinging frame 9 rotates toward the outdoor side around the fixed fulcrum _P1 , and the sliding vertical stile 4A travels toward the fixed fulcrum _P1 side of the swinging rod 9, and when it travels near the fixed fulcrum _P1 , the shoji B opens from the sash frame A at right angles toward the outdoor side. If the vertical frame 4B of the shoji B, which has been opened to the right angle, is rotated so as to incline toward the vertical frame 1 that is far from the fixed fulcrum P ₁ , the shoji B will become a sliding vertical frame that has traveled to the fixed fulcrum P ₁ side. The stile 4A rotates in the direction of the room, and as the shoji B rotates, the swinging rod 9 swings toward the inside of the sash frame A, and the inner surface b ₁ and the outer surface b ₂ of the shoji B It is closed in the inverted state as shown in Figure 2. You can return to the original state by performing the above operation in reverse.

Therefore, the proposed sash has an upper metal fitting with a head that rotates horizontally on one of the left and right vertical frames that make up the shoji, and a lower metal fitting with a horizontally rotating universal door wheel, and the sash is attached along the longitudinal direction of the sash frame. The other side is a sliding vertical stile that can move in and out, and the other side is a flexible vertical stile that can swing inward and outward directions around the sliding vertical stile. A swing rod is pivotally supported between the shoji and the outside so that the inside and outside surfaces of the shoji can be turned over from the indoor side, so the inside and outside surfaces of the shoji can be safely and easily cleaned indoors. Of course, opening/closing and reversing the shoji is also extremely easy. In particular, when the shoji is closed, it can be pulled toward the indoor side and come into close contact with the tight material of the sash frame, and the airtight piece provided on the arc wall of the vertical frame touches the vertical frame, so even if the shoji is reversed inside and out, it is airtight. Highly effective. In addition, it is easy to attach the upper and lower metal fittings to the shoji frame, the swing rods to the shoji frame and the sash frame, and it is easy to attach and remove the shoji from the sash frame, so cleaning the outside surface of the shoji is difficult and dangerous. It has a particularly beneficial effect as a window sash for high-rise buildings.
