DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment shown in FIGS. 1 to 4 is a case where the mechanism for fixing the end of the screen in the foldable screen device of the present invention is applied to a horizontally opening insect screen which is attached to an opening of a building. In the drawings, reference numeral 1 denotes a rectangular screen frame, 3 denotes a screen made of an insect-proof net attached to the screen frame 1 so as to be openable and closable, and 5 denotes an end of the screen 3. It is an operation frame for opening and closing operation.

The screen frame 1 is formed by connecting an upper frame member 1a and a lower frame member 1b and left and right side frame members 1c and 1d to each other with screws, and is fixed to a building opening by an appropriate means. I am getting it.

The screen 3 is provided with a large number of pleats to make it expandable and contractible in an accordion manner. The screen 3 is provided in the screen frame 1 so as to be openable and closable by expansion and contraction in the left and right directions. Are detachably fixed to the side frame member 1d of the screen frame 1 and the respective screen mounting frame portions 9 of the operation frame 5 by a fixing mechanism described in detail below.

As can be seen from FIGS. 1 to 4, the fixing mechanism includes a plate-shaped locking plate 11 attached substantially over the entire length of the screen 3 along an end thereof, which is engaged with the screen mounting frame 9. The locking plate 11 is locked in the locking groove 15 by locking the fixing tool 17 inside the locking protrusions 13, 13 provided on both sides of the rim of the housing portion formed by the locking groove 15. It is fixed to the state.

The locking plate 11 is made of a single synthetic resin plate, and the end of the screen 3 is adhered to one surface thereof. The configuration of the locking plate 11 is not limited to the above-described configuration, and includes a pair of plate-shaped holding portions made of a synthetic resin and a bent portion made of a soft synthetic resin interconnecting the holding portions. In this case, the locking plate may be bent into two at the position of the bent portion, and the end of the screen 3 may be sandwiched between the sandwiching portions, and may be interposed through the screen 3. The two holding portions are fixed to the end of the screen 3 by bonding each other.

As shown clearly in FIGS. 2 to 5, the fixing member 17 fixes the opposed portion 17a of the disk to the locking projections 13,1.
Notches are formed in parallel so as to be able to fit between the three, and a non-cut portion of the disc is a locking portion 17b for locking the inside of the locking ridge 13. The locking portion 17b is formed in a slope shape in which an upper surface side in contact with the inside of the locking protrusion 13 is thinned in both sides with the center in the width direction of the fixing tool 17 as a top portion, The engaging portion 17b can be more smoothly engaged and disengaged from the inside of the engaging protruding edge 13. On the surface of the disk, there is provided a rotation operation portion 17c for rotating the disk while being fitted between the locking projections 13, 13. This rotation operation unit 1
7c is configured as a groove into which a coin can be inserted and rotated, as shown in the figure, but may be configured to use a screwdriver or other tools.

As can be seen from FIGS. 2 and 3, between the locking plate 11 and the fixture 17, the fixture 1 is provided.
Positioning means 19 for the fixture 17 that provides the center of rotation when the fixture 17 is rotated by the rotation operation section 17c at the same time as positioning the fixture 7 is provided. The positioning means 19 includes an engagement hole 11a provided in the locking plate 11,
And the engaging projections 17d provided at the center of the fixing tool 17, and the screen mounting frame of the fixing tool 17 is formed by mutual engagement of the engaging holes 11a and the engaging projections 17d. This is for positioning the portion 9 in the longitudinal direction.

According to the mechanism for fixing the end of the screen 3 having the above configuration, the locking groove 15 of the screen mounting frame 9 is provided.
The locking plate 11 at the end of the screen 3 is accommodated in the fixing device 17, and the pair of opposing portions 17 a is connected to the locking projection 13,
13, the fixture 17 is rotated by a rotary operation part 17c in a state of being fitted between them so that the locking part 1
The end of the screen 3 can be firmly fixed to the screen mounting frame 9 by a simple operation of locking the 7b inside the locking projection 13. Then, the fixture 17 is rotated by the rotation operation portion 17c to release the locking of the locking portion 17b inside the locking protruding edge 17d, thereby easily removing the locking portion 17b from the screen mounting frame portion 9. be able to. At this time, the locking portion 17b
Since the upper surface of the locking projection 13 against which the inside of the locking projection 13 abuts is formed in a slope shape narrowed in both sides with the center in the width direction of the fixing tool 17 as the top, the locking projection of the locking portion 17b is formed. Engagement / removal to the inside of the edge 13 can be performed more smoothly. As described above, since the screen 3 can be easily attached and detached, the assembly of the screen device, the replacement of the screen 3, and the like can be performed extremely easily.

The locking plate 11 is provided with an engaging hole 11a for positioning the fixing tool 17 and at the same time providing a center of rotation of the fixing tool 17, and the center of the fixing tool 17 is provided with the engaging hole 11a.
a, the engaging projection 17d is held by the engaging hole 11a of the locking plate 11 when the fixing tool 17 is rotated, and the rotating operation of the fixing tool 17 is performed. The positioning of the fixture 17 in the screen mounting frame 9 can be performed more easily.

In the above embodiment, both end portions of the screen 3 are locked to the side frame member 1d of the screen frame 1 and the operation frame 5 by the locking plates 11, but depending on the structure of the screen device. When only one end of the screen 3 is attached to the side frame member 1d or the operation frame 5 by the locking plate 11, and the other end of the screen 3 is attached to the other operation frame 5 or the side frame member 1d directly or by other means. There is also. Alternatively, the operation frame 5 may be attached to both side ends of the screen 3 so that the screen 3 can be selectively used when the screen 3 is opened rightward or left.
