Now, taking the upper frame 3 as an example, the upper frame 3 is a fixed upper frame (corresponding to a fixed frame member of the present invention) 7 having a substantially sectional shape.
And a movable upper frame (corresponding to the movable frame member of the present invention) 8 having a substantially sectional shape, the movable upper frame 8 is a fixed upper frame that is vertically slidable. It is fitted on 7. That is, an adjustment liner 9 having a substantially shape in a side view is integrally attached to the inner sides of the left and right ends of the upper side 8a forming the movable upper frame 8 by screwing the upper piece 9a. Has been. A screw hole 9c is formed in the bottom surface 9b of the adjustment liner 9, and the screw hole 9c is formed.
The adjusting screw 11 is screwed in from below with the screw head 11a facing downward.

On the other hand, on the inner side of the frame of the lower side 7b forming the fixed upper frame 7, two front and rear bispokes 12 extending in the left-right direction are formed to face each other. Screws 13 for forming a frame and the frames 5a and 6a are screwed into the frame. And this pair of biscuits 12
Have openings on the opposite sides facing each other in a groove shape. The screw head 11a of the adjusting screw 11 is fitted and locked in the opening groove 12a so that the screw head 11a is allowed to rotate around the shaft center and is prevented from moving back and forth in the shaft center direction.

Further, the lower side 7b of the fixed upper frame 7 is provided with a tool hole 7c for rotating the adjusting screw 11. And adjusting screw
When the screw head 11a is rotated with an appropriate tool, the movable upper frame 8 moves the adjustment liner 9 up and down without moving back and forth in the axial direction with respect to the fixed upper frame 7. It is configured to be able to slide up and down.

To assemble the movable upper frame 8 to the fixed upper frame 7, use the screw head.
The movable upper frame 8 may be slid from one of the left and right sides of the fixed upper frame 7 by fitting the front and rear edges of the fixed upper frame 7 into the opening groove 12a. 5a, 6a
The front end of the frame screw 13 for forming the frame just comes into contact with the screw head 11a of the adjusting screw 11, whereby the movable upper frame 8 moves in the left-right direction with respect to the fixed upper frame 7. It is configured to be positioned.

In addition, the left and right vertical frames 5, 6 are fixed vertical frames 5a, like the upper frame 3,
It has a double frame structure consisting of 6a and movable vertical frames 5b and 6b.
The movable vertical frames 5b and 6b are adapted to slide in the left-right direction by the rotation of the adjusting screw 11. And these movable upper frames 8
By sliding the movable vertical frames 5b and 6b inward and outward, the outer dimensions in the height direction and the left-right direction of the screen frame 1 can be adjusted according to the building dimension.

Furthermore, one side surface portion of the movable upper frame 8 projects outward, and a storage portion 14 is formed between it and one side surface portion of the fixed upper frame 7, and the storage portion 14 has a corner plate. 15 is slidable in the left-right direction and is fitted so as to move integrally in the up-down direction. On the other hand, the outer edge of the corner plate 15 is formed with an engaging piece 15a protruding from the edge of the movable upper frame 8, and the engaging piece 15a is formed on the movable vertical frames 5b and 6b. The groove 16 is slidable in the vertical direction, but is engaged in the horizontal direction so as to move integrally. When the movable upper frame 8 is slid in the vertical direction, the corner plate 15 moves up and down integrally with the vertical movement of the movable upper frame 8. At this time, the engagement piece 15a is engaged with the engaging groove 1a.
As it slides inside 6, the amount of protrusion of the corner plate 15 from the movable upper frame 8 is maintained as it is, and the gap between the corner portions generated between the movable vertical frames 5b and 6b is closed. On the other hand, when the movable vertical frames 5b and 6b are slid in the left-right direction, the corner plate 15 has the engaging pieces 15a whose movable vertical frames 5b and 6b.
It is engaged with the engaging groove 16 of the upper frame 3 and moves integrally with the movable vertical frames 5b and 6b in the left-right direction.
The gaps formed at the corners between the vertical frames 5 and 6 can be automatically closed by the corner plates 15.

In the embodiment of the present invention constructed as described above, as described above, the upper frame 3 and the vertical frames 5, 6 are fixed frame members 7, 5a, 6a.
And the movable frame members 8, 5b, 6b have a double frame structure. By sliding the movable frame members 8, 5b, 6b inward and outward, the outer dimensions in the height direction and the left-right direction of the screen frame 1 can be adjusted. Although it can be adjusted, when the upper frame 3 is taken as an example, an adjusting screw 11 for sliding the movable upper frame 8 has its screw head 11a fitted to a screw pocket 12 formed on the fixed upper frame 7. This restricts the movement back and forth. Accordingly, when the adjusting screw 11 is rotated to adjust the upper frame 3, the adjusting liner 9 can be moved up and down without moving the adjusting screw 11 to the fixed upper frame 9 in the axial direction. As a result, the movable upper frame 8 integrated with the adjustment liner 9 moves in the vertical direction, and the position of the upper frame 3 can be adjusted.

As described above, in the present invention, the regulation of the forward / backward movement of the adjusting screw 11 is achieved by only fitting and locking the screw head 11a to the screw pocket 12 necessary for forming the fixed frame members 7, 5a, 6a as a frame. It can be done with a simple structure, and parts such as a screw cover and a screw receiving liner are not required as in the past.
