Description

  The present invention relates to a door device with a screen door. More specifically, the present invention relates to a so-called French door type door device with a screen door provided with a main door and a child door.

  Conventionally, as a screen door device to be attached to, for example, a front door, a folding screen door device having a net that can be expanded and contracted laterally in an accordion manner by applying pleats is disclosed in Japanese Utility Model Laid-Open No. 5-3591. . In addition, a two-fold (middle fold) type screen door device is well known in which two left and right screen doors having a net attached to a rectangular screen door frame made up of frame members surrounding the upper, lower, left and right sides are joined by hinges. ing.

  Furthermore, Japanese Patent Application Laid-Open No. 2000-110465 discloses a sliding screen device for an entrance that can open and close an opening by sliding a plurality of divided screens in the width direction of the opening. .

  However, a foldable folding screen door device that has been subjected to pleating processing has a low durability because the pleat itself is easily damaged and the net itself is easily damaged when the opening and closing operation of the net is repeated. Although the folding screen door device and the sliding screen door device are structurally stronger than the foldable folding screen door device, the folded screen door and sliding are overlapped. Since a space for accommodating the screen door is required, it may be necessary to abandon the attachment because such a space cannot be secured.

  In addition, since any screen door device requires a special and complicated configuration, the device itself is expensive and the cost required for its installation is also expensive.

  Therefore, an object of the present invention is to provide a door device with a screen door that has a simple structure and does not require a large space for mounting.

  In order to achieve the above object, a door device with a screen door according to the present invention is rotatably installed on one side of an opening of a building and rotatably on the other side of the opening. And a screen door that is substantially the same size as the child door, and is installed on the side of the opening where the child door is installed so as to be rotatable in a direction opposite to the child door. Have.

  According to the above door device with a screen door, since the screen door is substantially the same size as the child door, it can be greatly reduced in size as compared with the size having a size covering the entire opening of the building. Moreover, since it is not necessary to make a screen door into a complicated structure like a folding door type or a slide type, the cost of the screen door itself and its attachment cost can be held down.

  Further, in a door device having a main door and a child door as in the present invention, the doors are normally opened and closed only by opening and closing the main door, and therefore the screen door is not normally opened and closed when entering and leaving. In the configuration where the screen door covers the whole opening of the building, the screen door is opened and closed every time it enters and exits, so the screen door is likely to break down. Can be suppressed.

  Furthermore, it is good also as a structure which has the latch receptacle provided in the said screen door in order to receive the latch of the said main door when the said child door is opened and the said screen door is closed.

  When the parent door and the child door are in the closed position, the latch of the parent door is locked to the latch receiving of the child door, so that the parent door is not opened carelessly by wind or the like. However, since the latch of the parent door is not locked to the latch receiver of the child door when the child door is opened, the parent door may be opened carelessly by wind or the like unless some measure is taken. Therefore, by providing a latch receiver as in the present invention, the latch of the main door is locked to the latch receiver of the screen door fixed in the closed position, thereby preventing the parent door from being inadvertently opened. It becomes possible to do.

  The latch receiver has a fixed member fixed to the screen door, and a movable member provided with an opening for receiving the latch of the parent door and provided rotatably with respect to the fixed member. The fixed member and the movable member are provided with a locking portion for locking the movable member and the fixed member to each other when the movable member is opened at a predetermined angle with respect to the fixed member. It is good also as a structure.

  Further, the locking portion engages with the first uneven portion formed on the fixed member and the first uneven portion when the movable member opens at a predetermined angle with respect to the fixed member. Thus, it may be configured to include a second uneven portion formed on the movable member.

  As described above, the door device with a screen door according to the present invention includes a main door that is rotatably installed on one side of an opening of a building, and a child that is rotatably installed on the other side of the opening. The structure has a door and a screen door that is substantially the same size as the child door, and is installed on the side where the child door of the opening is installed so as to be rotatable in a direction opposite to the child door. A door device with a screen door that is simple and does not require much space for mounting can be provided.

  Furthermore, when the child door is opened and the screen door is closed by having a latch receiving device provided in the screen door to receive the latch of the parent door when the child door is opened and the screen door is closed. It is possible to prevent the parent door from opening carelessly.

  Next, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is an overall perspective view showing an embodiment of a door device with a screen door according to the present invention. FIG. 1 shows a state in which the door device is viewed from the outside of the building. Moreover, FIG. 2 is the figure which looked at the door apparatus with a screen door shown in FIG. 1 from the upper side.

  This door device is pivotally attached to one side of the opening of the building via a hinge 1a and rotatably attached to the other side of the opening via a hinge 2a. This is a so-called French door that has two doors, the main door 1 and the child door 2, which are opened outward. Such a door apparatus is installed in the entrance of a building, for example. Such a French door is usually used with the child door 2 closed, and a person enters and exits the building by opening and closing only the main door 1. On the other hand, when it is desired to widen the opening, both the main door 1 and the child door 2 are opened to the outside of the building. 1 and 2 show a state in which the main door 1 is in the closed position and the child door 2 is in the open position.

  A door check 1c is provided on the upper part of the main door 1, and the main door 1 is held at either the open position or the closed position by the door check 1c. In addition, a French drop 2b is provided at the lower part of the child door 2, and by locking the French drop 2b in a recess provided on the floor surface corresponding to the open position and the closed position of the child door 2, The child door 2 is fixed at either the open position or the closed position.

  The door device with a screen door according to the present embodiment is provided with a screen door 3 having the same size as the child door 2 with respect to the door device as described above. If it mainly demonstrates with reference to FIG. 3, the screen door 3 is rotatably attached through the hinge 3a to the side by which the child door 2 of the opening part of the building is attached. The child door 2 can be opened and closed outside the building, whereas the screen door 3 can be opened and closed inside the building. An upper French drop 3c and a lower French drop 3d are provided at the upper and lower portions of the screen door 3, respectively. When the screen door 3 is in the closed position, the upper French drop 3c is locked to a metal fitting attached to the upper beam of the opening of the building, and the lower French drop 3d is locked to a recess provided on the floor. By doing so, it is possible to fix the screen door 3 in the closed position. When the screen door 3 is fixed at the open position, the lower French drop 3d is locked in a recess provided on the floor surface corresponding to the open position of the screen door 3.

  As shown in FIG. 2, when the child door 2 is opened, a gap is formed between the screen door 3 and the main door 1, and insects or the like may enter the building from the gap. In the embodiment, a seal rubber 5 is provided to close the gap. The seal rubber 5 is attached to the frame 3b of the screen door 3 so as to extend over the entire length in the vertical direction, for example.

  As described above, the child door 2 is not used when the French door is normally in and out. Therefore, the screen door 3 corresponding to the child door 2 is provided as in the present embodiment, and the child door 2 is fixed in an open state, so that the area where the child door 2 is opened can be used as an insect-proof ventilation opening. It becomes possible. If the area can be used as an insect ventilating opening, the insect ventilating effect can be sufficiently obtained.

  According to this configuration, since it is sufficient that the screen door 3 has approximately the same size as the child door 2, it is possible to greatly reduce the size as compared with a size having a size covering the entire opening of the building. Therefore, even if the screen door 3 is configured as a single sheet that can be opened and closed by the hinge 3a, a large space is not required for opening and closing. Moreover, since it is not necessary to make the screen door 3 into a complicated structure like a folding door type or a slide type, the cost of the screen door 3 itself and its installation cost can be kept low.

  In a French door type door device having a main door and a child door as in the present embodiment, since the normal door is opened and closed only by opening and closing the main door 1, the screen door 3 is not normally opened and closed during the door. In the conventional configuration in which the screen door covers the entire opening of the building, the screen door is opened and closed every time it enters and exits, and the screen door is likely to break down. However, in the configuration of the present embodiment, the screen door 3 is less frequently opened and closed. Can last longer.

  When the parent door 1 and the child door 2 are in the closed position, the latch 1b of the parent door 1 is locked to the latch receiver 2c of the child door 2 fixed in the closed position by the French drop 2b (see FIG. 1). At this time, the main door 1 does not open carelessly with respect to the child door 2 due to wind or the like. However, as shown in FIG. 2 and the like, since the latch 1b of the main door 1 is not locked to the latch receiver 2c of the sub door 2 in a state where the sub door 2 is opened, the main door 1 is windless unless some measures are taken. May open accidentally. Therefore, in the door device with a screen door of the present embodiment, the latch receiving metal 4 (see FIG. 2 and the like) that receives the latch 1b of the main door 1 when the child door 2 is opened is provided on the frame 3b of the screen door 3. Yes. Since the screen door 3 is fixed in the closed position by the French drop 3c, 3d, the main door 1 is inadvertently opened by locking the latch 1b of the main door 1 to the latch receiving metal 4 provided on the screen door 3. Can be prevented.

  Here, the latch bracket 4 will be described with reference to FIGS. 4 is a perspective view showing the latch receiving metal fitting, FIG. 5 is an exploded perspective view of the latch receiving metal fitting, and FIG. 6 is a diagram for explaining the operation of the latch receiving metal fitting.
