As shown in FIG. 3, the base member 1 has a flat plate portion 11 extending in the expected direction, the indoor side end of the flat plate portion 11 is bent at a right angle to the right, and the tip is folded back to the left and fixed. As part 4. The fixing portion 4 is provided with screw holes 41 at two locations, upper and lower. A convex notch is formed in the approximate center of the flat plate portion 11 with the interior side as the base, and the inner portion of the notch is raised to the right at a right angle to form the base finding surface 12. Further, the inclined surface 13 is formed by bending the tip of the base finding surface 12 to the outdoor side by 45 degrees. Further, a rectangular insertion hole 14 is formed at the base portion of the base finding surface 12. Then, the upper and lower ends of the outdoor portion of the flat plate portion 11 are bent in a U shape toward the right side to form the mounting groove 15 of the movable member 2 (however, in actual manufacturing, the base member 1 and the movable member 2 are combined. The base member 1 is bent to form the mounting groove 15).

  As shown in FIG. 4, the movable member 2 has a flat plate portion 21 extending in the expected direction, and the indoor side end of the flat plate portion 21 is bent at right angles to the right to form a movable finding surface 22. Furthermore, the upper end portion and the lower end portion of the movable finding surface 22 are extended and curved inward to form a curved surface 23. In addition, U-shaped cuts are formed in the upper and lower parts of the movable locating surface 22 (in the direction of cutting the upper and lower sides of the rectangle and the left side), and the inner part of the cuts is raised to the outdoor side by approximately 15 degrees. The stop 5 is provided. And the inner side operation part 6 is provided in the up-down center part of the indoor side end (base of movable movable surface 22) of the flat plate part 21, and the inner side operation part 6 is extended to the indoor side, and is bent rightward on the way. doing. Furthermore, the outdoor side end of the flat plate portion 21 is bent to the right at a right angle to form the outer operation portion 7.

  The screen door lock component is configured by combining the base member 1 and the movable member 2. As shown in FIG. 5, the upper and lower ends of the flat plate portion 21 of the movable member 2 are fitted in the upper and lower mounting grooves 15 of the base member 1, and the inner operation portion 6 passes through the insertion hole 14 of the base finding surface 12. (In actual manufacturing, after the inner operation portion 6 is passed through the insertion hole 14, the base member 1 is bent to form the attachment groove 15). A knob portion 61 made of resin and having a substantially cubic shape is attached to the tip of the inner operation portion 6. By combining in this way, the flat plate portion 11 of the base member 1 and the flat plate portion 21 of the movable member 2 are parallel, and the movable member 2 is slidable in the expected direction with respect to the base member 1. However, the movable range is up to a position where the movable finding surface 22 abuts on the indoor side end of the mounting groove 15 to the outdoor side (the state of FIG. 1). 2 to the position where it abuts (the state of FIG. 2). The base locating surface 12 faces the indoor side and the movable locating surface 22 faces the outdoor side, and an urging member 3 made of a coil spring is attached therebetween, and the movable member 2 is attached to the outdoor side. It is fast. Due to the urging member 3, the movable member 2 is normally located on the most outdoor side (the state shown in FIG. 1). Note that the tip portion of the base finding surface 12 enters between the upper and lower curved surfaces 23 of the movable finding surface 22.

  As shown in FIGS. 1 and 2, the screen door lock component configured as described above sandwiches the finding surface of the outdoor end of the window frame 100 of the sash by the fixing portion 4, and screws 42 into the screw holes 41 from the outdoor side. Screw in and fix. When the screen door lock component is attached, the base finding surface 12 and the movable finding surface 22 are arranged at positions facing the door side surface of the screen door 110. The screen door (vertical shaft) 111 has a groove 112 on the side surface of the door tip, and the door end side end of the outdoor wall of the groove 112 is bent toward the indoor side to form the locked portion 8. . When the screen door 110 is closed in the left direction, the base finding surface 12 and the movable finding surface 22 are swallowed into the groove 112 of the screen door rod 111. At that time, the tip of the base finding surface 12 is an inclined surface 13 that is inclined to the outdoor side, and the tip of the movable finding surface 22 is a curved surface 23 that curves to the indoor side. The base finding surface 12 and the movable finding surface 22 smoothly enter the groove 112 without the entrance being caught. When the movable finding surface 22 enters the groove 112, the locked portion 8 of the screen door 111 comes into contact with the locking portion 5 of the movable finding surface 22. The locking portion 5 has a shape that is gently inclined with respect to the locked portion 8 that contacts from the right side and gradually protrudes to the outdoor side. Therefore, as the screen door 110 is closed, the locked portion 8 rides on the locking portion 5 and the movable member 2 is gradually pushed indoors against the biasing force of the biasing member 3. When the screen door 110 is further closed, the locked portion 8 gets over the locking portion 5 and reaches the left side of the locking portion 5, and the movable member 2 is pushed back to the outdoor side again by the biasing force of the biasing member 3. Then, since the latching | locking part 5 latches the to-be-latched part 8 from the right side, it becomes impossible to open the screen 110 (state of FIG. 1). That is, when the screen door 110 is closed, the screen door 110 is automatically locked. In order to open the screen door 110 again from this state, the inner operation unit 6 is pulled from the indoor side or the outer operation unit 7 is pushed from the outdoor side to move the movable member 2 against the urging force of the urging member 3 on the indoor side. (See the state of FIG. 2). Then, since the latching | locking part 5 leaves | separates from the to-be-latched part 8, and latching is cancelled | released, what is necessary is just to open the screen 110, maintaining the state.

  As shown in FIG. 6, the screen door lock component 120 is used by being attached to the left and right ends of the sash. By doing in this way, even if the screen door 110 is closed on either the left side or the right side of the sash, it is automatically locked.

  As described above, according to the screen door lock part of the present invention, when the screen door is closed, the locking portion automatically locks the screen door lock and locks the screen door. However, the screen door can be surely prevented. Further, since the screen door lock part is attached to the window frame and does not need to be processed, the screen door itself can be easily attached to an existing sash provided with the screen door. Further, by providing the operation unit on the outdoor side, when the screen door is attached to a window such as a veranda where people enter and exit, the screen door can be unlocked even from the outdoor side.

  In the screen door lock component of the present invention, the movable member 2 has a wide space between the movable finding surface 22 and the outer operation portion 7. By doing in this way, as shown in FIG. 7, even when it applies to the screen door 110a with the wide expected width | variety of the screen door 111a, the outer side operation part 7 does not interfere with the screen door 111a. Even in this case, when the screen door 110a is closed, the base finding surface 12 and the movable finding surface 22 are squeezed into the groove 112a of the screen door rod 111a, and the locking portion 5 locks the locked portion 8a. 110a is automatically locked.

  The present invention is not limited to the above embodiment. For example, the base member may be any member that can be fixed to the window frame and that can hold the movable member slidably. Therefore, the shape of the fixing portion can be freely designed according to the shape of the window frame, and may not necessarily have the base finding surface as long as there is a structure capable of supporting the biasing member. Further, the movable member may be attached to the base member so as to be slidable and may have a locking portion. Therefore, the inner operation part and the outer operation part can be freely designed in consideration of the ease of operation and the influence of surrounding interference, and if there is a structure that can support the biasing member, the movable finding surface is not necessarily provided. It may not have. Further, the urging member may be a plate spring or the like in addition to the coil spring.
