Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a raised/lowered window that is installed in an opening in a building.

(Prior art) In order to make it easier to fit the shoji into the window frame later on, there was a type of conventional lift-down window that had a removable partition separating the inner and outer shoji.
It is shown in No. 44876 and Utility Model Publication No. 61-113888.
These ideas include installing a spring-type balancer inside the vertical frame as a means of supporting the shoji, and then attaching a partition after the shoji is fitted into the window frame, making the work of fitting the shoji easier. The partition was designed to reduce the gap between the window frame and the shoji, and to prevent the shoji from swinging sideways or wobbling.

(Problem that the invention aims to solve) However, with the above-mentioned lift-down window, because the shoji is fitted to the window frame later, a horizontal gap is created between the window frame and the shoji, so when opening and closing the window, The shoji swayed laterally, causing the stile to often come into contact with the stile, making it impossible to open and close the shoji smoothly.Furthermore, when the shoji was open, it sometimes rattled due to the wind.

Therefore, an object of the present invention is to provide a lift-and-lower window that not only allows the shoji to be easily fitted into the window frame, but also prevents the shoji from rattling during opening/closing operations or in the open state.

[Structure of the idea]

(Means for Solving the Problems) In order to achieve the above object, in the present invention, steady rest pieces that can be moved in and out of the vertical frame are inserted into both ends of the upper stile.

(Example) An example of the raising/lowering window according to the present invention will be specifically described with reference to the drawings. Shoji 1 upper stile 2
, a horizontal upper wall 4 and a lower wall 5 are provided at the middle part of the chip between the inner wall 3 and the outer wall 3b, a horizontal cylindrical part 6 is formed in the upper stile 2, and an upwardly extending cylindrical part 6 is formed in the upper part of the upper wall 4. A groove 16 is provided in the lower part of the lower wall 5, and a downward groove 7 into which a glass is fitted is provided, and a long hole 7 is bored in both ends of the upper wall 4 along the longitudinal direction of the upper stile 2.

Further, reference numeral 8 in the figure indicates a steady rest piece that is inserted into and out of the cylindrical portion 6 of the upper stile 2. The steady rest piece 8 is generally box-shaped when viewed from above, and has a concave curved portion 20 at its tip that can protrude from the cylindrical portion 6.
A screw 9 is drilled in the center, and the screw hole 9 of the steady rest piece 8 is inserted through the long hole 7 from the outer periphery of the upper stile 2.
The steady rest piece 8 is fixed by tightening the screw 11, and by loosening the screw 11, the steady rest piece 8 is moved from the cylindrical part 6 to the vertical frame 10 within the drilling range of the upper wall elongated hole 7. It becomes possible to appear in the direction.

On the other hand, the vertical frame 10 of the window frame has four partition walls 12 protruding from the inner circumferential side, with the partition walls 12a, 12a on the indoor side being a pair, and the partition walls 12b, 12b on the outdoor side being a pair, A spring type balancer 13 for raising and lowering the shoji screen is installed between each partition wall 12, 12, respectively.

The balancer 13 consists of an outer cylinder 13a fixed between the partition walls 12, 12, and a spring, and an inner body 13a.
Inner body 13 that enters and exits downward from the outer cylinder 13a of b.
A horizontal bar 13c is provided at the lower end that is engaged between the inner and outer bodies 13a and 13b, and the connecting member 15 attached to the end of the shoji lower stile 18 is hung on the horizontal bar 13c to suspend the shoji 1.

As is clear from the drawing, the concave portion 20 of the steady rest piece 8 is concavely curved with approximately the same curvature as the outer diameter of the outer cylinder 13a of the balancer 13.

The vertical window 14 having the above structure is constructed by fitting the shoji 1 between the window frames 10 and 10 with the steady rest piece 8 housed in the cylindrical part 6, and attaching the shoji 1 to the horizontal sill 13c of the balancer 13 to the shoji lower stile 18. connecting member 15
After locking the shoji 1 and suspending the shoji 1, loosen the screw 11 to project the left and right steady rest pieces 8 to the side, and bring the concave curved portion 20 at the tip as close as possible to the outer cylinder 13a of the balancer 13 without contacting it. , tighten the screw 11 to fix it.

When the shoji 1 fitted in this way is opened and closed up and down, the concave curved portion 20 at the tip of the steady rest piece 8 is close to the outer peripheral surface of the outer cylinder 13a over its entire curved surface, so that there is no lateral vibration between the two. There is no gap large enough to cause rattling in the indoor-outdoor direction, the steady rest piece 8 slides up and down on the outer circumferential surface of the outer tube 13a, and the shoji 1 moves up and down smoothly without lateral vibration. Also, even when the windows are open, they do not rattle due to the wind for the same reason.

[Effect of idea]

As described above, the lift-down window according to the present invention has a cylindrical part opening in the direction of the vertical frame in the upper stile, and steady rest pieces are inserted into and out of both ends of the cylindrical part,
The amount of protrusion of the steady rest piece can be adjusted using a screw that is screwed into the steady rest piece through a long hole drilled in the upper wall of the cylindrical part, so that the steady rest piece can be stored in the cylindrical part. This creates a margin between the window frame and the shoji, allowing the shoji to be easily fitted into the window frame.

Also, after fitting the shoji into the window frame, if the steady rest piece is projected in the direction of the vertical frame and the concave curve formed at the tip of the steady rest piece is brought as close as possible to the outer cylinder of the balancer inside the vertical frame without contacting it. , the gap between the outer cylinder of the balancer fixed to the vertical frame and the concave curved part of the steady rest piece fixed to the shoji screen is almost eliminated over the entire concave curved part, resulting in lateral vibration and rattling in the indoor and outdoor directions. This allows the shoji to be opened and closed smoothly up and down at all times, and eliminates rattling when the shoji is open.
