It is integrally formed.

  In the state where the open / close lid 30 is closed in this way (FIG. 3), the base end piece 33a of the lid side guide portion 33 is horizontal (front side) with respect to the guide portion main body 18a of the frame side guide portion 18. The lid-side vertical guide piece 33b is adjacent to the frame-side vertical guide piece 18b on the front side of the frame-side guide portion 18, and the lid-side vertical guide piece 33b is adjacent to the lid-side vertical guide piece 18b. The horizontal guide piece 33c extends in the back direction along the guide portion main body 18a on the outer side of the frame body 6 with respect to the frame side guide portion 18.

  At this time, the edge portions 8c and 8d extending in the horizontal direction on the screen 8 are respectively introduced into the first and second horizontal frames 4 and 5 from the inside of the frame body 6 as shown in FIGS. The frame-side vertical guide piece 18b and the lid-side vertical guide piece 33b are sandwiched between the frame-side vertical guide piece 18b and along the guide body 18a by the lid-side horizontal guide piece 33c at the tip of the frame-side vertical guide piece 18b. The locking member 9 is bent at a right angle to the back surface direction (horizontal direction), and the distal end of the lid-side horizontal guide piece 33c abuts on the proximal end 9a of the locking member 9, whereby the locking member 9 is The pressure is applied from the 9a side toward the tip side. As a result, the screen 8 is stretched between the first and second horizontal frames with appropriate tension applied in the vertical direction.

  Hereinafter, a method for stretching the screen 8 to the frame 6 will be described. First, as described above, in the slit 13a of the inner rail 14a attached to the first vertical frame 2 and in the slit 13b of the inner rail 14b attached to the movable frame 3b of the second vertical frame 3, The locking members 9, 9 of the corresponding peripheral edge portions 8a, 8b of the screen 8 are respectively inserted, and both horizontal ends of the screen 8 are connected to the first vertical frame 2 and the movable frame 3b of the second vertical frame 3. Prepare one held by engagement.

  Next, as shown in FIGS. 5 and 6, the opening and closing lids 30 and 30 of the first and second horizontal frames 4 and 5 are opened, and rail portions 3c provided at the upper and lower ends of the movable frame 3b, 3c is inserted into the guide grooves 16a and 16a of the horizontal fixed frames 10 and 10, respectively, the first vertical frame 2, the vertical fixed frame 3a of the second vertical frame 3, and the first and second Both ends of the horizontal fixed frames 10, 10 of the horizontal frame are connected to each other. At this time, as shown in FIG. 7, the other end portion of the leaf spring 22 held by the spring holding portion 34 linearly connects one end of the leaf spring 22 and the axis L1 (L2). It is arranged at a position that is sufficiently farther from the front side than L3 and that can apply a counterclockwise moment to the opening / closing lid 30. Therefore, the opening / closing lid 30 is urged in the opening direction around the axis L1 (L2) by the elastic force of the curved leaf spring 22.

  Then, from the state of FIGS. 5 and 6, the movable frame 3b is slid in the horizontal direction (right direction in the figure), and is received and locked in the receiving groove 12a of the vertical fixed frame 3a as shown in FIG. By doing so, the frame body 6 is formed. Then, the screen 8 is stretched between the first vertical frame 2 and the second vertical frame 3 in a state where a predetermined appropriate tension is applied in the horizontal direction (horizontal direction). At this time, as shown in FIG. 7, the edge portions 8 c and 8 d extending in the lateral direction of the screen 8 are arranged so that the locking members 9 and 9 are located outside the frame body 6 than the frame side guide portions 18 and 18. The horizontal fixed frames 10 and 10 of the horizontal frames 4 and 5 and the open / close lids 30 and 30 are arranged.

  From this state, when the open / close lids 30, 30 of the horizontal frames 4, 5 are rotated around the axes L 1, L 2 to the closed state shown in FIG. 2 and FIG. Edge edges 8c and 8d extending in the lateral direction are sandwiched between the frame-side vertical guide piece 18b and the lid-side vertical guide piece 33b, and the lid-side horizontal guide piece at the tip of the frame-side vertical guide piece 18b. By 33c, it bends at right angles to the back direction along the said guide part main body 18a. Then, the front end of the lid-side horizontal guide piece 33c facing the back surface comes into contact with the base end 9a of the locking member 9, so that the lid-side horizontal guide piece 33 is engaged with the locking member 9, The locking member 9 is pressed from the proximal end 9a side toward the distal end side, that is, toward the back side. As a result, the screen 8 is stretched between the first and second horizontal frames in a state where a predetermined appropriate tension is uniformly applied in the vertical direction.

  At that time, as shown in FIG. 3, the other end portion of the leaf spring 22 held by the spring holding portion 34 linearly connects the one end of the leaf spring 22 and the axis L1 (L2). It is arranged at a position where it can be sufficiently separated from the line L3 to the back side so that a clockwise moment can be applied to the opening / closing lid 30. Therefore, the opening / closing lid 30 is biased in the closing direction around the axis L1 (L2) by the elastic force of the curved leaf spring 22. Further, since the first protrusion 21a of the frame side guide portion 18 functions as a stopper of the locking member 9, it is possible to prevent an unnecessary tension from being applied to the screen 8 when the opening / closing lid 30 is closed. can do.

  Thus, in the screen device 1A, after the movable frame 3b is locked in the receiving groove 12a of the vertical fixed frame 3a and the frame body 6 is assembled, the first and second horizontal frames 4 and 5 are opened and closed. The screen 8 can be stretched in the frame 6 in a state where predetermined moderate tensions are uniformly applied in the vertical direction and the horizontal direction by an extremely simple operation of closing the lid 30. As a result, it is possible to further reduce the work time required for mounting the screen device (screen door) 1A on the window frame F in the field.

The rotating portion 25 of the second embodiment is formed by a flexible bent portion 51 that connects the outer peripheral wall 17 and the lid plate 31, and is folded by applying a force in the rotating direction to the lid plate 31. The opening / closing lid 30 can be opened and closed by changing the bending angle of the bending portion 51. Such a bent portion 51 is formed by using a resin softer than the portion adjacent to the bent portion 51, that is, the outer peripheral wall 17 and the cover plate 31, when the opening / closing lid 30 is integrally molded with resin. Can be formed.

  Here, in order to lock the opening / closing lid 30 to the lateral fixing frame 10 and hold it in the closed state, in the present embodiment, the lid side horizontal guide piece 33c constituting the lid side guide portion 33 is attached to the tip thereof. A shaped locking claw 52 a is provided toward the inside of the frame body 6, and a locked projection 41 is erected on the guide body 18 a toward the outside of the frame body 6. Then, as shown in FIG. 8B, when the opening / closing lid 30 is closed, the locking claw 52a is engaged with the locked protrusion 41 so that the closed state is maintained. Yes.

Further, the lid side horizontal guide piece 33c is engaged with the screen 8 by applying a predetermined tension to the screen 8 by pressing the engaging element 9 of the screen 8 from the base end 9a side toward the front end side. The protrusion 52b is provided so as to protrude toward the inside of the frame body 6 (the guide section main body 18a side).
When the opening / closing lid 30 is closed, the engagement protrusion 52b comes into contact with the base end 9a of the engagement element 9 from the front side, and the engagement element 9 is moved to the distal end side (FIG. 8 ( It is pressed toward the left side in b), that is, the back side of the screen holding frame.

  Therefore, even in the second embodiment, after assembling the frame body 6 by locking the movable frame 3b in the receiving groove 12a of the vertical fixed frame 3a as in the first embodiment, FIG. And as shown in FIG. 8 (b), the screen 8 is moved in the vertical direction and the horizontal direction by a very simple operation of closing the open / close lids 30 of the first and second horizontal frames 4 and 5, respectively. It can be stretched in the frame body 6 with a uniform tension applied. As a result, it is possible to further reduce the work time required for mounting the screen device (screen door) 1B on the window frame F at the site.

As mentioned above, although the embodiment of the screen device according to the present invention has been described in detail, the present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the scope of the claims.
