  1 to 7 show a first embodiment of a rotary opening / closing type screen door apparatus according to the present invention. As shown in FIGS. 1 to 3, this rotary opening / closing type screen door apparatus 1 mainly has a building opening 2 that allows a person to enter and exit by installing a sliding door or the like. In the illustrated embodiment, the sash 3 attached to the building opening 2 can be used on the outside of the glass shoji 4 without being used. The above-described rotary opening / closing type screen door apparatus 1 can be mounted using the screen door mounting rail 3a of the sash 3. However, it is not limited to such an installation mode.

  1 to 4 will be described in detail. The screen door apparatus 1 basically includes a pair of left and right vertical outer frame members 11 and a pair of upper and lower horizontal frame members 12 in a square shape. The outer frame 10 is configured by coupling to the outer frame 10 and the pair of left and right vertical frame members 21 and the pair of upper and lower horizontal frame members 22 that are fitted into the outer frame 10 and are squarely coupled. A net 24 is stretched in the screen door frame 23, and at a middle position corresponding to the pair of horizontal frame members 22, a pair of upper and lower horizontal outer frame members 12 of the outer frame 10 are connected to the vertical frame 13 by a vertical rotation shaft 13. A screen door 20 that is rotatably supported, and a holding mechanism 30 that holds the screen door 20 in a state of being fitted in the same plane in the outer frame 10 are provided.

  More specifically, the outer frame 10 to be mounted on the building opening 2 includes a mounting bracket 14 for mounting on the screen door mounting rail 3a of the sash 3, thereby being fixed to the rail 3a. A pair of upper and lower horizontal outer frame members 12 in the outer frame 10 are attached to the support members 13 a of the pair of vertical rotating shafts 13 along the outer frame member 12 by the rolling wheels 15. The central part of the upper and lower horizontal frame members 22 in the screen door frame 23 is rotatably supported by the vertical rotation shafts 13. Accordingly, the screen door frame 23 is rotatably supported by the outer frame member 12 by a pair of upper and lower vertical rotation shafts 13.

  In order to exhibit the insect-proof function, the screen door 20 needs to be held in the outer frame 10 so as to be fitted in the same plane as the outer frame 10, and the holding mechanism 30 is in this position. Specifically, as shown in FIG. 3 and FIG. 4, it protrudes elastically from a part of the vertical frame member 21 of the screen door frame 23, etc. The projection is attached to the concave portion of the vertical outer frame member 11 of the outer frame 10 to prevent the screen door 20 from rotating, but the vertical frame of the screen door frame 23 due to the rotation of the screen door 20 When a part of the material 21 is pressed, the projection is easily detached from the recess and the screen door 20 rotates. Further, the space between the outer periphery of the screen door frame 23 and the inner periphery of the outer frame 10 is sealed by a sealing material 31 such as mohair or an elastic material so that insects do not enter. The function of the holding mechanism 30 can also be combined.

  The support member 13a of the vertical rotating shaft 13 is supported by a roller wheel 15 and can be moved laterally along the upper and lower outer frame members 12 of the outer frame 10 by the roller wheel 15. When the outer frame 10 is fitted in the same plane as the outer frame 10, the outer frame 10 cannot be laterally moved due to the presence of the outer frame 10. In the lateral movement along, the screen door 20 is rotated around the vertical rotation shaft 13 as shown in FIG. 3 and then moved as shown in FIG.

  In the above embodiment, as described above, the support member 13a of the vertical rotating shaft 13 is supported by the rolling wheel 15 so as to be laterally movable along the outer frame member 12, but the screen door frame 23 is vertically movable. It can be connected to the vertical rotation shaft 13 at the center of the frame member 22, and the vertical rotation shaft 13 can be supported at the center of the upper and lower outer frame members 12 in the outer frame 10 so as not to move laterally. Furthermore, the screen door frame 23 is connected to the vertical rotation shaft 13 at a position offset from the center to one side instead of the center of the upper and lower horizontal frame members 22, and the upper and lower horizontal outer frame members 12 in the outer frame 10. Similarly, the vertical rotation shaft 13 may be supported so as not to move laterally at a position deviated to one side.

  As described above, when they are connected by the vertical rotation shaft 13 at a position deviated from the center of the screen door frame 23 and the outer frame 10, especially when the vertical rotation shaft 13 is not laterally moved, While the width of the passage portion when the screen door 20 is opened is limited by the position of the vertical rotation shaft 13, the screen door 20 is pressed by pressing the vertical frame member 21 side further away from the vertical rotation shaft 13 in the screen door frame 23. By opening and closing, the width of the passage portion when the screen door 20 is opened can be set large as in the case where the vertical rotation shaft 13 is moved laterally by the rolling wheel 15.

  When the pair of vertical rotating shafts 13 are supported so as to be laterally movable along the upper and lower lateral outer frame members 12 in the outer frame 10, the pair of upper and lower vertical rotating shafts 13 are laterally moved in synchronization with each other. However, if it is not possible, the screen door 20 may be tilted and cannot be moved smoothly. As the linkage means 33 that synchronizes the lateral movement, for example, as shown in FIGS. 5 to 7, a loop-shaped wire 34 inserted into one vertical outer frame member 11 of the outer frame 10, respectively, The vertical outer frame member 11 is turned at the upper and lower ends and inserted into the horizontal outer frame member 12, and both ends thereof are respectively wound around the turners 35 on the other end side of the upper and lower horizontal outer frame members 12. It is possible to employ a configuration in which the support members 13a of the vertical rotating shaft 13 are connected to the wires 34 on different sides in the upper and lower lateral outer frame members 12 by being folded back. As a result, as can be seen from FIGS. 4 and 5, when the screen door 20 that has been rotated is moved laterally, the vertical rotary shafts 13 are always synchronously moved in the same direction. However, the linkage means 33 is not necessarily limited to such a configuration.

  Further, the screen door 20 in the open state as shown in FIG. 4 is disposed on the pair of vertical rotation shafts 13 when the rotation shaft position is in the same plane as the outer frame 10 in the outer frame 10. A return mechanism 25 that elastically returns and moves toward is provided. As the return mechanism 25, as illustrated in FIG. 5, one end 26a of a tension spring 26 is fixed in one vertical outer frame member 11 of the outer frame 10, and a wire 27 connected to the other end is connected to the outer frame. The position of the rotary shaft 13 when the screen 11 is led to the end of the material 11 and is turned by the turning device 28 into the horizontal outer frame material 12 and the screen door 20 is in the same plane as the outer frame 10 in the outer frame 10. It is possible to adopt a means such as connecting to the support member 13a of the vertical rotating shaft 13 through the turning element 29 provided in the structure. When such a return mechanism 25 is used, the tensile force of the tension spring 26 is used as a return force that returns the vertical rotary shaft 13 to the position shown in FIG. Will work. In addition, when it is desired to temporarily hold the screen door 20 at the moving position of the screen door 20 as shown in FIG. 4, a locking tool for temporarily locking the screen door 20 is attached to the position. There is a need.

  In the first embodiment, as shown in FIGS. 3 and 4, the outer frame 10 of the screen door device 1 is fixed to the right side of the sash 3 with the mounting bracket 14. Can be fixed to the left side of the sash 3, and without the mounting bracket 14 being fixedly attached to the screen door mounting rail 3a of the sash 3, the right and left outer sides of the sash 3 can be fixed by the sliding bracket. It can also be moved between.

  This rotary opening / closing type screen door device is premised on opening a part of the screen door 20, preferably a part of the screen door frame 23, by pressing it with a hand or a part of the body. In order to avoid pressing the net 24, a part of the net 24 is covered with a porous plate 24a made of metal or synthetic resin used for pressing.

  The rotary opening / closing type screen door apparatus of the first embodiment having the above-described configuration is installed in a building opening where a person enters and exits, and when a person tries to enter and exit from the opening 2, both hands are blocked or both hands are Even if it is difficult to open the screen door by hand because it is dirty or wet, the screen door frame 23 and the perforated plate 24a are opened in other parts of the body, such as arms, shoulders, feet, or the whole body. By pressing the side, the screen door 20 can be opened against the closing force of the holding mechanism 30, and the return mechanism 25 is provided to release the screen door frame 23 and the like. Sometimes the screen door 20 can be automatically closed. Further, the screen door 20 rotated around the vertical rotation shaft 13 can be moved laterally, and the screen door is pressed in the lateral movement direction by a part of the body or the like, as in the case of opening the screen door 20. By doing so, the width | variety of the channel | path part by opening of the screen door 20 can be expanded further.

  In the second embodiment shown in FIGS. 8 to 10, in the rotary opening / closing type screen door apparatus 1 of the first embodiment, a part of the screen door frame 23 is pressed to rotate the screen door 20 around the vertical rotation shaft 13. An interlocking mechanism 40 is provided for interlocking the opening of the screen door 20 by the rotation of the screen door 20 and the operation of moving the rotating shaft 13 along the outer frame material 12 beside the outer frame 10. Therefore, only the interlocking mechanism 40 will be described below, and portions common to the first embodiment will be denoted by the same reference numerals as those of the first embodiment in the drawing, and the configuration and operation thereof will be described. Omitted.

As a specific configuration of the interlocking mechanism 40, as clearly shown in FIG. 8, the support member 13 a for lateral movement of the vertical rotation shaft 13 passes through a turning element 42 at one end of the outer frame 10, and the screen door Using the flexible linkage wire 41 connected to one end of the outer frame 10 in the screen door frame 23 of 20 can reduce the cost with a simple configuration, but other configurations can also be used.
According to such an interlocking mechanism 40, when the left side portion of the screen door 20 in the figure is pressed from the state shown in FIG. 9, the screen door 20 rotates and opens as shown in FIG. The support member 13a is pulled to the right side by a flexible connecting wire 41 connected to the screen door frame 23 via a turning element 42 on one side end of the outer frame 10, and the vertical rotation shaft 13 is one of the horizontal outer frame members 12. In other words, not only can the mesh door 20 be pressed to open the screen door, but also the width of the passage portion can be expanded by opening the screen door only by the pressing operation. be able to.

Further, in the rotary opening and closing type screen door apparatus provided with the interlock mechanism 40, if the return mechanism 45 having the same configuration as the return mechanism of FIG. 5 described above is provided, the screen door 20 interlocks with the rotation around the vertical rotation shaft 13. Then, the vertical rotation shaft 13 moved laterally can be elastically returned to the original position along the horizontal outer frame member 12 and simultaneously the screen door 20 can be returned to the original closed position.
