[Detailed description of the device]

[0001]

[Industrial applications]

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

[0002]

[Prior art]

  As for the screen door, the net is stretched on the screen frame which has a rectangular frame with upper and lower horizontal frames and left and right vertical frames. The length of the vertical frame is larger than the length of the upper and lower horizontal frames, that is, the height For screen doors with a large ratio to the width, the left and right vertical frames are pulled inward by the tension of the net. Since it is stretched and bent, the frame body for the screen door is deformed, so attach the middle joint between the left and right vertical frames and It prevents bending and prevents the screen frame from being deformed.   In this way, the frame body for screen doors with the middle shell attached makes it unattractive. Since dust adheres to the inner shell, as disclosed in Japanese Patent Laid-Open No. 1-125487. A method of making a screen door was proposed in which the frame for the screen door was not deformed without attaching the middle shell. ing.

[0003]

[Problems to be solved by the device]

  In the above-mentioned screen door manufacturing method, the left and right vertical frames are previously curved outwardly so as to be convex. , Install an adjustable jig between the left and right vertical frames and pull the left and right vertical frames inward. Place the net in the correct rectangular frame shape, then remove the adjustment jig and Since the force is supported by the restoring force of the left and right vertical frames, making the screen door is very troublesome, and Not only is it troublesome to manufacture the left and right vertical frames that are convexly curved outward, but also the tension of the net It is difficult to balance the force and the restoring force of the left and right vertical frames, and the length can be adjusted freely. Since a rectifying jig is required, ordinary people cannot change the net at home after installing the screen door. Yes.

[0004]   Therefore, the present invention provides a frame body for a screen door capable of solving the above-mentioned problems. aimed to.

[0005]

[Means for Solving the Problems]

  Reinforcing vertical members are arranged in the left and right vertical frames, and the screws screwed from the outside of the left and right vertical frames are reinforced. Pressed against the outer surface of the vertical member.   Move the left and right vertical frames to the main body and the inward recess of the main body to move the net mounting body in the in-plane direction. The upper and lower inner frames of the left and right main body are inserted in the longitudinal direction of the upper and lower horizontal frames. The one that connects the ends.

[0006]

[Work]

  By adjusting the pressing force of the screw, the left and right vertical frames bent inward are bent outward Can be straightened.   The net mounting body bends and moves in the in-plane direction with respect to the main body, so the external shape is correct It has a rectangular frame shape.

[0007]

【Example】

  As shown in FIG. 1, both longitudinal end surfaces 1a, 1a of the upper horizontal frame 1 and the longitudinal direction of the lower horizontal frame 2 Both end faces 2a, 2a are connected to the upper and lower inner side faces 3a of the left and right vertical frames 3, 3 to form a rectangular frame. The frame body 4 for the screen door is constructed, and the left and right vertical frames 3 and 3 are arranged on one side plate 10 and the other side as shown in FIG. The plate 11 is integrally connected with the inner connecting plate 12 and the intermediate connecting plate 13 so as to connect with the hollow portion 14 and face outward. It has a recess 15 and a hook piece 16 for attaching a net is integrally provided on the inner connecting plate 12. Both ends of the hook piece 16 in the longitudinal direction are notched so that both sides of the inner connecting plate 12 in the longitudinal direction are cut. The ends are the inner surfaces 3a, 3a of the upper and lower parts, and the screws 17 are attached to the upper and lower horizontal frames from the inner connecting plate 12. Reinforcing vertical members are screwed into the screw holes 1 and 2 and connected to the inside of the hollow portion 14 of the vertical member 3. 18 is inserted, and a screw 19 screwed into the central portion of the intermediate connecting plate 13 in the longitudinal direction is reinforced vertically. It is in contact with the outer surface of the material 18.   Therefore, when the net is stretched over the screen frame 4, the left and right vertical frames 3, 3 are 1 As shown in phantom lines and in FIG. 3, the screen frame 4 for the screen door is bent by bending the inside by the tension of the net. It deforms like a lump, but tightens the screw 19 and presses it against the outer surface of the reinforcing vertical member 18. By bending it, and by bending the vertical member 3 outward with the reaction force of the reinforcing vertical member 18. By making the screen frame straight, the screen frame 4 can be formed in a correct rectangular frame shape.

[0008]   Next, a second embodiment will be described.   As shown in FIGS. 4 and 5, the left and right vertical frames 3, 3 are formed from the main body 20 and the net mounting body 21. The main body 20 is composed of the one side plate 22, the other side plate 23, and the connecting plate 24, and the inward concave portion 25. A long member having a cross-sectional shape having an outward concave portion 26 is provided, and the net mounting body 21 is formed into an inward concave portion. 25 has a hook piece 27 that is movably inserted in the in-plane direction and that protrudes inward. It becomes a long material with an empty cross section, and this net mounting body 21 is Only the upper and lower sides of the main body 20 are shortened by the vertical method, and both longitudinal end faces of the upper and lower horizontal frames 1 and 2 are provided. 1a and 2a are butted against each other and connected, and the net attachment body 21 is placed between the upper and lower horizontal frames 1 and 2. positioned.   Because of this, the net attachment body 21 is attached to the main body 20 and the upper and lower horizontal frames 1 and 2. Of the hooks 1b and 2b of the upper and lower horizontal frames 1 and 2 and the net mounting body 21. When the net is stretched on the hook piece 27, the net mounting body 21 is bent inward by the tension of the net. However, since the main body 20 does not bend, the outer shape of the screen frame 4 is a square frame. Become a state.

[0009]

[Effect of device]

  The left and right vertical frames 3, 3 are screwed onto the outer surface of the left and right reinforcing vertical members 18 by pressing the screws 19. It is possible to bend the screen frame 4 into a correct rectangular frame shape by bending it outward against the tension of the screen. The screen door can be easily manufactured, and the vertical member 3 can be easily manufactured in a straight shape. Moreover, tighten the screw 19 while watching the curved state of the vertical frame 3 due to the tension of the net. Not only can the frame body 4 for the screen door be easily made into the correct rectangular frame shape, but a special jig It becomes unnecessary and ordinary people can exchange online at home.   Nets are stretched on the net attachments 21 and 21 of the upper and lower horizontal frames 1 and 2 and the left and right vertical frames 3 and 3. The outer shape of the screen frame 4 can be made into a correct rectangular frame shape simply by making it easier to manufacture the screen door. However, the vertical frame 3 can be manufactured linearly and easily, and no adjustment work is required. Then, ordinary people can exchange online at home.
