[Industrial applications]

 The present invention relates to a frame for a screen door.

[0002]

[Prior Art]

 A screen is a screen frame that is constructed by arranging the upper and lower horizontal frames and the left and right vertical frames in a rectangular shape.The length of the vertical frame is greater than the length of the upper and lower horizontal frames, that is, the height. In the case of a screen door with a large ratio to the width of the screen, the left and right vertical frames are pulled inward by the tension of the net and bend, and the frame for the screen door is deformed.Therefore, a middle shaft is installed between the left and right vertical frames to bend the vertical frame. This is done to prevent the screen frame from being deformed. As described above, a frame for a screen door to which the inner shell is attached looks unattractive and dust adheres to the inner shell, so that the inner shell is attached as disclosed in JP-A-1-125487. Without fail, a method of manufacturing a screen door has been proposed in which the frame for the screen door is prevented from being deformed.

[0003]

[Problems to be solved by the device]

 In the above-mentioned screen door manufacturing method, the left and right vertical frames are bent in a convex shape outward in advance, and an adjustment jig whose length can be adjusted is attached between the left and right vertical frames to draw the left and right vertical frames inward to form a correct rectangular frame shape. Since the net is stretched and the adjustment jig is removed after that, the net tension is supported by the restoring force of the left and right vertical frames, which makes the screen door extremely troublesome, and the left and right sides that are convexly curved to the outside Not only is it difficult to manufacture the vertical frame, it is difficult to balance the tension of the net and the restoring force of the left and right vertical frames, and a length adjustment adjustable jig is required. The general public cannot exchange the internet.

Therefore, an object of the present invention is to provide a frame for a screen door that can solve the above problems.

[0005]

[Means for Solving the Problems]

 The vertical frame contact surfaces of the upper and lower horizontal frames 1 and 2 are inclined to the outside at a slight angle with respect to the right angle, and the vertical frame contact surfaces of the upper and lower horizontal frames are attached to the upper and lower portions of the inner surfaces of the left and right vertical frames with a plurality of screws. Those that are connected.

[0006]

[Work]

 By adjusting the tightening degree of the screws after the net is stretched, the left and right vertical frames can be bent outward against the net tension.

[0007]

【Example】

 As shown in FIG. 1, both longitudinal end surfaces 1a and 2a, which are vertical frame contact surfaces of the upper horizontal frame 1 and the lower horizontal frame 2, are inclined by 1 ° to 2 ° toward the outside with respect to a right angle. The upper and lower sides of the inner side surfaces 3a of the left and right vertical frames 3, 3 are butted against the longitudinally opposite end surfaces 1a, 2a of the diagonal upper and lower horizontal frames 1, 2 and temporarily tightened with two screws 4 as shown in FIG. Then, the frame 5 for the screen door is formed. When the net 6 is stretched in this state, the left and right vertical frames 3, 3 are pulled inward by the tension of the net 6 and bent as shown by phantom lines in FIG. 3, so that the screen frame 5 is deformed. And tighten the upper and lower parts of the inner side surfaces 3a of the left and right vertical frames 3, 3 close to the diagonally opposite longitudinal end surfaces 1a, 2a of the upper and lower horizontal frames 1, 2 and connect the left and right vertical frames 1, 2 to the net 6. The frame 5 for the screen door is formed into a correct rectangular frame shape by bending it outward by bending it against the tension of.

Next, a specific example will be described. As shown in FIGS. 4 and 5, the upper horizontal frame 1 includes a main body 14 in which one side vertical plate 10 and the other side vertical plate 11 are integrally connected by an inner plate 12 and an intermediate plate 13, and an inner plate 12 thereof. The vertical piece 15 and the horizontal piece 16 are integrally provided with an L-shaped hook piece 17 so as to have a groove groove 18. Notches are formed at both ends of the horizontal piece 18 of the hook piece 17 in the longitudinal direction. The vertical frame 3 forms a main body 24 in which one side vertical plate 20 and the other side vertical plate 21 are integrally connected by an inner side plate 22 and an intermediate plate 23, and a vertical piece 25 is formed on the inner side plate 22. An L-shaped hook piece 27 is integrally provided on the horizontal piece 16 to form a shape having a groove groove 28. Both longitudinal ends of the hook piece 17 are cut out by the vertical width of the upper horizontal frame 1. , Two longitudinal ends 4a of the upper horizontal frame 1 in the longitudinal direction are abutted against the inner side surface 3a of the vertical frame 3, that is, the inner side plate 22. Inner plate 12 than the side plate 22 upper lateral frame 1, bi is formed in the intermediate plate 13 Suhoru 12a, it is to be connected threadably to 13a. The same applies to the lower horizontal frame 2.

Next, a second embodiment will be described. As shown in FIG. 6, the left and right vertical frames 3, 3 are brought into contact with both longitudinal end faces 1a, 2a of the upper and lower horizontal frames 1, 2 via a wedge-shaped spacer 30 and fastened with two screws 4, 4. Thus, one side surface 30a of the spacer 30 and the other side surface 30b form an angle of about 1 ° to 2 °, and the one side surface 30a abuts on both longitudinal end faces 1a, 2a of the upper and lower horizontal frames 1, 2. The other side surface 30b comes into contact with the inner side surface 3a of the left and right vertical frame 3, so that the vertical frame contact surfaces of the upper and lower horizontal frames 1 and 2 are inclined outward at an angle of 1 ° to 2 ° with respect to the right angle. I am

[Effect of the device]

 After the net is stretched, the left and right vertical frames 3, 3 can be bent outward against the tension of the net by adjusting the tightening degree of the screws 4, so that the screen frame 5 for the screen door can be formed into a correct rectangular frame shape. Therefore, it is only necessary to adjust the tightening degree of the screws 4 while watching the curved state of the vertical frame 3, which facilitates the manufacture of the screen door, and the right and left vertical frames 3, 3 can be straight, which facilitates the manufacture. In addition, the frame body 5 for the screen door can be formed into a correct rectangular frame shape, and since no special jig is required, the net can be exchanged by ordinary people at home.
