Description

Door and window

Technical Field

The present invention relates to a door/window having door/window sashes capable of switching opening/closing directions.

Background

As a door window that can open and close door sashes in a plurality of opening and closing directions, an inwardly opened and inwardly tilted window is known. In the internal opening and internal reversing window, the opening and closing directions of the door and window sash can be switched, so that the door and window sash can be opened in 2 opening modes of internal opening and internal reversing. Further, there have been known doors and windows in which: switching of the opening and closing directions of the door sash and opening and closing of the door sash are performed using 1 handle (see patent document 1).

In the conventional door window described in patent document 1, the handle is rotatable 180 degrees and arranged in 3 directions, i.e., a downward direction (0 degree direction), a lateral direction (90 degree direction), and an upward direction (180 degree direction). When the handle is arranged in the downward direction, the door sash is locked. Further, the inward opening of the door sash can be achieved when the handle is arranged in the lateral direction, and the inward falling of the door sash can be achieved when the handle is arranged in the upward direction.

As described above, in the conventional door window, the handle is rotated in 3 directions to operate the door window, and the door window is opened and closed in each opening and closing direction by using the handles arranged in different directions. Therefore, the operation of the handle is troublesome, and may affect the operability of the handle. In particular, when the handle is arranged in the upward direction, it is difficult to open and close the door sash by the handle because the handle is positioned at a high position. Further, the opening and closing direction of the door sash needs to be determined according to the direction of the handle, which may make it impossible to easily determine the opening and closing direction of the door sash. In addition, the inward-opening window can be inverted when the handle is arranged in the horizontal direction, and can be opened inward when the handle is arranged in the upward direction. As a result, the direction of the handle does not coincide with the opening/closing direction of the door sash, and it is more difficult to determine the opening/closing direction of the door sash.

Patent document 1: japanese patent laid-open No. 2014-145202.

Detailed Description

An embodiment of a door window of the present invention will be described with reference to the accompanying drawings.

The door window of the present embodiment is an opening/closing window in which door leaves can be opened and closed in a plurality of opening/closing directions. Hereinafter, 2 embodiments of the door window will be described by taking an inwardly opening/closing window (inwardly opening/inwardly opening window) as an example.

Embodiment 1

Fig. 1 and 2 are perspective views of a door/window 1A (tilt-in window) according to embodiment 1, and schematically show a schematic configuration of the door/window 1A as viewed from the indoor side. Fig. 1 shows the door/window 1A in the inward-tilted state, and fig. 2 shows the door/window 1A in the inward-tilted state.

As shown in the figure, the door/window 1A has: a side frame 2 provided at an opening of a building, and a door sash 3 openably and closably attached to the side frame 2. The opening 10 of the side frame 2 can be opened and closed by the door and window 3.

The side frame body 2 is a rectangular opening frame (window frame) and is attached to an edge portion (opening edge portion) surrounding an opening portion of a building. The frame body 2 has 4 long frame members 11 to 14 (the 1 st frame member 11, the 2 nd frame member 12, the 3 rd frame member 13, and the 4 th frame member 14) constituting a frame, and the opening 10 is formed by the frame members 11 to 14. The 1 st frame member 11 is an upper frame member, and the 2 nd frame member 12 is one vertical frame member. The 3 rd frame member 13 is a lower frame member, and the 4 th frame member 14 is the other vertical frame member.

The door/window sash 3 is a rectangular opening/closing body (inner-falling/inner-opening door/window sash) and has: a frame body 20 provided with a plurality of frame members, and a panel body 25 attached to the frame body 20. The frame body 20 includes 4 long frame members 21 to 24 (1 st frame member 21, 2 nd frame member 22, 3 rd frame member 23, and 4 th frame member 24) constituting a frame, and is disposed along an edge portion of the panel body 25. The frame 20 has an opening 26 formed by the frame members 21 to 24. The frame members 21 to 24 are disposed at different edge portions 3A to 3D (1 st edge portion 3A, 2 nd edge portion 3B, 3 rd edge portion 3C, and 4 th edge portion 3D) of the door sash 3 in a state where the end portions of the frame members 21 to 24 are continuous with each other. The panel body 25 is, for example, a double-glazing unit having a multiple-glazing unit, and is disposed in the opening 26 of the frame 20 and held by the frame 20. The 1 st frame member 21 is an upper frame member, and the 2 nd frame member 22 is one vertical frame member. The 3 rd frame member 23 is a lower frame member, and the 4 th frame member 24 is the other vertical frame member. The 4 frame members 21-24 are arranged along different side frame members 11-14 in the side frame body 2.

The door/window sash 3 is connected to the side frame 2 so as to be switchable in opening and closing directions, and is openable and closable in 2 opening and closing directions (1 st opening and closing direction M1, 2 nd opening and closing direction M2). The 1 st opening/closing direction M1 is the opening/closing direction of the door sash 3 when the door is tilted inward, and the 2 nd opening/closing direction M2 is the opening/closing direction of the door sash 3 when the door is opened inward. When the door/window 3 is opened and closed in the opening and closing directions M1 and M2, the door/window is rotatably supported by the side frame 2, and is moved (rotated) in the opening directions H1 and H2 or the closing directions T1 and T2 to be opened and closed. The opening directions H1 and H2 of the door 3 are the moving directions (pivoting directions) of the door 3 when the door 3 is opened with respect to the side frame 2, and the closing directions T1 and T2 of the door 3 are the moving directions of the door 3 when the door 3 is closed with respect to the side frame 2. The door sash 3 is movable to a closed position V for closing the opening 10 of the side frame body 2 or open positions W1 and W2 for opening the opening 10 of the side frame body 2.

When opening and closing in the 1 st opening and closing direction M1 (see fig. 1), the 1 st frame member 21 moves in the 1 st opening direction H1 or the 1 st closing direction T1 about the 3 rd frame member 23 in a state where the 3 rd frame member 23 is held by the side frame body 2. Thereby, the door sash 3 moves (rotates) in the 1 st opening direction H1, and opens so as to tilt toward the indoor side. The door sash 3 is moved to the 1 st opening position W1 and is placed in a fall-in state (1 st opening state). The door sash 3 moves in the 1 st closing direction T1 and is closed so as to be lifted toward the side frame 2. The door sash 3 is moved to the closed position V and is arranged in a closed state.

When opening and closing in the 2 nd opening and closing direction M2 (see fig. 2), the 2 nd frame member 22 moves in the 2 nd opening direction H2 or the 2 nd closing direction T2 about the 4 th frame member 24 in a state where the 4 th frame member 24 is held by the side frame body 2. Thereby, the door sash 3 moves in the 2 nd opening direction H2 and opens toward the indoor side. The door sash 3 is moved to the 2 nd opening position W2 and is placed in the inward opening state (the 2 nd opening state). Further, the door sash 3 is moved in the 2 nd closing direction T2 to be closed. The door sash 3 is moved to the closed position V and is arranged in a closed state.

Fig. 3 is a front view showing the structure of the door/window 1A according to embodiment 1, and shows the door/window 1A as viewed from the indoor side. In fig. 3, a part of the frame body 20 is schematically shown by a two-dot chain line to show the internal structure of the door window 1A. Fig. 4 is a side view showing the structure of the door/window 1A as viewed from the direction of arrow X1 in fig. 3. In fig. 4, the cross sections of the 1 st frame member 11, the 3 rd frame member 13, the 1 st frame member 21, and the 3 rd frame member 23 are shown by two-dot chain lines. Fig. 5 is a plan view showing the structure of the door/window 1A as viewed from the direction of arrow X2 in fig. 3. In fig. 5, the cross sections of the 2 nd frame member 12, the 4 th frame member 14, the 2 nd frame member 22, and the 4 th frame member 24 are shown by two-dot chain lines.

As shown, the door and window 1A includes: a switching member 4 for operating switching of opening and closing directions M1 and M2 of the door sash 3, an opening and closing mechanism 40 for opening and closing the door sash 3 in the opening and closing directions M1 and M2, a switching mechanism 5 for switching the opening and closing directions M1 and M2 of the door sash 3, an operating member 6 for operating opening and closing of the door sash 3, and a lock mechanism 7 for locking the door sash 3 to the side frame 2. The switching member 4 and the operating member 6 are different members that operate independently of each other, and are provided in the door sash 3. The switching member 4 is a switching operation member for switching the opening and closing directions M1 and M2 of the door sash 3, and is connected to the switching mechanism 5. The opening/closing mechanism 40 has a 1 st hinge mechanism 8 and a 2 nd hinge mechanism 9, and connects the door/window sash 3 to the side frame body 2 so as to be openable and closable in a plurality of opening/closing directions M1 and M2. The operating member 6 is an opening/closing operating member for opening/closing operation of the door sash 3 including operation of the lock mechanism 7, and is connected to the lock mechanism 7.

When the opening and closing directions M1 and M2 of the door sash 3 are switched, the switching member 4 is operated to operate the switching mechanism 5. The switching mechanism 5 is operated by the switching member 4 to switch the opening and closing directions M1 and M2 of the door sash 3. When the door sash 3 is opened and closed, the operating member 6 is operated to operate the lock mechanism 7. When the door sash 3 is opened, the lock mechanism 7 is operated by the operating member 6 to unlock the door sash 3 and the side frame 2. The opening and closing of the door sash 3 in the opening and closing directions M1 and M2 (see fig. 1 and 2) switched by the switching mechanism 5 is operated by the operating member 6.

The 1 st hinge mechanism 8 (see fig. 3) is a lower hinge mechanism (lower support mechanism) that rotatably supports one lower corner portion of the door sash 3 (one end portion of the 3 rd frame member 23), and connects the one lower corner portion of the door sash 3 to the 3 rd frame member 13 of the side frame 2. The 1 st hinge mechanism 8 is a well-known hinge mechanism for a tilt-in window, and has: the door sash assembly includes a mounting member 8A attached to the frame 20 of the door sash 3, a base member 8B fixed to the 3 rd frame member 13 of the side frame 2, and a plurality of link members 8C. The mounting member 8A, the base member 8B, and the plurality of link members 8C are rotatably connected at the respective connecting portions, and support the door sash 3 so as to be rotatable in the 1 st opening/closing direction M1 and the 2 nd opening/closing direction M2.

The 2 nd hinge mechanism 9 (see fig. 3) is an upper hinge mechanism (upper support mechanism) for rotatably supporting one upper corner portion of the door sash 3 (one end portion of the 1 st frame member 21), and connects the one upper corner portion of the door sash 3 to the 1 st frame member 11 of the side frame body 2. One upper corner portion of the door sash 3 is supported by the 2 nd hinge mechanism 9 so as to be rotatable in the 2 nd opening/closing direction M2. When the door 3 is opened and closed (opened inward) in the 2 nd opening and closing direction M2 (see fig. 2), the 2 nd hinge mechanism 9 rotates the door 3 to the indoor side (the 2 nd opening direction H2) or the side frame body 2 side (the 2 nd closing direction T2) while moving the 4 th frame member 24 to the indoor side. The door/window 3 is supported by the 1 st hinge mechanism 8 and the 2 nd hinge mechanism 9 so as to be openable and closable in the 2 nd opening/closing direction M2. When the door sash 3 is opened and closed in the 1 st opening and closing direction M1 (in the reverse direction) (see fig. 1), the 2 nd hinge mechanism 9 releases the support of the door sash 3 and restricts the opening angle (tilt angle) of the door sash 3.

The switching member 4 and the operating member 6 are provided in the same frame member in the frame 20 of the door sash 3, and are disposed apart from each other in the longitudinal direction of the same frame member. The switching mechanism 5 and the lock mechanism 7 are provided in parallel to the same frame member in the frame 20 of the door sash 3 and are arranged along the longitudinal direction of the same frame member. Here, the switching member 4 and the operating member 6 are provided on the 2 nd frame member 22 and are arranged in parallel in the vertical direction. The switching mechanism 5 and the lock mechanism 7 are provided in parallel with the 1 st frame member 21 and the 2 nd frame member 22.

Fig. 6 is a front view showing the operation member 6 and the lock mechanism 7 according to embodiment 1, and a part of fig. 3 is enlarged. In fig. 6, the switching member 4 and the switching mechanism 5 are omitted.

As shown in the figure, the door sash 3 is provided with a frame body 20 including a 1 st frame member 21 and a 2 nd frame member 22. The 1 st frame member 21 is disposed at the 1 st edge 3A (upper edge) of the door sash 3, and the 2 nd frame member 22 is disposed at the 2 nd edge 3B (one longitudinal edge) of the door sash 3.

In the door/window 1A, the lock mechanism 7 is a latch device 30, and is provided in the 1 st frame member 21, the 2 nd frame member 22, and the side frame body 2. The latch device 30 is an example of a locking mechanism 7 that connects the door sash 3 with the side frame body 2 and locks the door sash 3 to the side frame body 2. The lock mechanism 7 (latch device 30) maintains the door 3 in the closed state, and releases the lock between the door 3 and the side frame 2 in conjunction with a release operation by the operating member 6 when the door 3 is opened.

The lock mechanism 7 has: a latch 31 movably provided to the door sash 3, a latch holder 32 housing the latch 31, and a link mechanism 33 provided to the frame 20 and linking the operating member 6 and the latch 31. The latch 31 is provided to the 1 st frame member 21 of the door sash 3. The latch base 32 is provided on the 1 st frame member 11 arranged in parallel with the 1 st frame member 21 in the side frame body 2, and is disposed at a position facing the latch 31. The interlocking mechanism 33 is provided on the 1 st frame member 21 and the 2 nd frame member 22, and is disposed along the longitudinal direction of the 1 st frame member 21 and the 2 nd frame member 22.

Fig. 7 and 8 are sectional views of the side frame body 2, the frame body 20, and the lock mechanism 7 (latch device 30), and show the door/window 1A taken along line X3-X3 in fig. 6. Fig. 7 shows a state where the door sash 3 is locked to the side frame body 2, and fig. 8 shows a state where the locking of the door sash 3 is released.

As shown in the drawing, the latch 31 is an engaging member protruding toward the latch base 32, and the latch base 32 is a holding member engaging with the latch 31 to hold the latch 31. In the state where the door sash 3 is closed, the latch 31 is disposed to face the latch base 32, and the latch 31 moves in a direction approaching the latch base 32 or in a direction separating from the latch base 32.

The latch 31 is moved to an engagement position K1 (see fig. 7) where it is engaged with the latch holder 32 or a non-engagement position K2 (engagement release position) (see fig. 8) where the engagement with the latch holder 32 is released, and is disposed at an engagement position K1 or a non-engagement position K2. At the engagement position K1, the latch 31 connects the 1 st frame member 21 of the frame body 20 to the 1 st frame member 11 of the side frame body 2, and locks the door sash 3. In the non-engagement position K2, the latch 31 releases the connection between the 1 st frame member 21 and the 1 st frame member 11, and releases the lock of the door sash 3. Thus, the 1 st frame member 21 of the frame body 20 is released from the 1 st frame member 11 of the side frame body 2, and the door sash 3 can move in the opening directions H1 and H2.

The biasing unit 34 of the lock mechanism 7 biases the latch 31 toward the engagement position K1. The biasing unit 34 includes a biasing member 34A and a holding pin 34B for holding the biasing member 34A, and constantly biases the latch 31 via the biasing member 34A. The urging member 34A is an elastic member (e.g., a spring or rubber), and is disposed in a recess 31A formed in the latch 31. Here, the biasing member 34A is a spiral spring (compression coil spring) and is disposed around the holding pin 34B.

When the latch 31 moves from the engagement position K1 to the disengagement position K2, the biasing member 34A is compressed, and the biasing member 34A and the holding pin 34B are housed in the recess 31A of the latch 31. The latch 31 is biased by the biasing unit 34 (biasing member 34A) from the non-engagement position K2 to the engagement position K1, and is disposed at the engagement position K1.

The latch base 32 has a projection 32A projecting toward the latch 31, and is attached to the 1 st frame member 11 of the side frame body 2 by attachment means (here, screws). The latch holder 32 is disposed above the latch 31 in a state where the door sash 3 is closed. The latch 31 is disposed at the engagement position K1 and engages with the projection 32A of the latch holder 32. Thereby, the latch 31 engages with the latch holder 32 to maintain the door sash 3 in the closed state.

When the door sash 3 is opened, the latch 31 moves from the engagement position K1 to the disengagement position K2, and is disengaged from the latch holder 32. In this state, the door sash 3 is moved in the opening directions H1 and H2, and the door sash 3 is opened. After the door sash 3 starts to move, the latch 31 is moved from the non-engagement position K2 to the engagement position K1 by the biasing force of the biasing unit 34. When the door sash 3 is closed, the door sash 3 moves in the closing directions T1 and T2, and the latch 31 at the engagement position K1 contacts the latch holder 32. At this time, the inclined portion 31B of the latch 31 contacts the protruding portion 32A of the latch holder 32.

The inclined portion 31B of the latch 31 is inclined with respect to the closing directions T1, T2 of the door sash 3 and the urging direction of the urging unit 34 to the latch 31. As the door sash 3 is closed, the inclined portion 31B of the latch 31 is pressed by the protrusion 32A of the latch holder 32, and the latch 31 moves from the engaging position K1 toward the non-engaging position K2. When the door sash 3 is closed, the latch 31 moves to a position where it can engage with the latch holder 32, and is disengaged from the projection 32A of the latch holder 32. At the same time, the latch 31 is moved to the engagement position K1 by the biasing force of the biasing unit 34, and is engaged with the latch holder 32.

Fig. 9 and 10 are perspective views showing the lock mechanism 7 and the operation member 6 provided in the housing 20. Fig. 9 shows a state where the latch 31 is disposed at the engagement position K1, and fig. 10 shows a state where the latch 31 is disposed at the non-engagement position K2.

As shown in the drawing, the link mechanism 33 of the lock mechanism 7 is a transmission mechanism that transmits the movement of the operation member 6 to the latch 31 to move the latch 31. The operating member 6 and the latch 31 are provided on different frame members (1 st frame member 21 and 2 nd frame member 22) of the door sash 3, and are moved in association with each other by the association mechanism 33. Further, the movement of the latch 31 is operated by the operating member 6. As the operating member 6 moves, the interlocking mechanism 33 is operated to move the latch 31 to the non-engagement position K2. The interlocking mechanism 33 interlocks with the operation (releasing operation of the engagement) of the operating member 6 to release the engagement of the latch 31 with the latch holder 32.

The link mechanism 33 includes: a slide member 35 that slides in conjunction with the operation of the operation member 6, a displacement member 36 that displaces in conjunction with the movement of the latch 31, and a guide member 37 that guides the displacement member 36. The slide member 35 is an elongated rod-like member and is disposed along the longitudinal direction of the 2 nd frame member 22. One end of the slide member 35 is a connecting portion 35A connected to the operation member 6, and the other end of the slide member 35 is a contact portion 35B in contact with the displacement member 36. The slide member 35 is slidably disposed on the 2 nd frame member 22, and slides in the longitudinal direction of the 2 nd frame member 22 in accordance with the movement of the operating member 6 (see arrow S).

Fig. 11 is a view showing the operating member 6 and the slide member 35 provided to the 2 nd frame member 22, and shows the slide member 35 and the 2 nd frame member 22 as cut along line X4-X4 in fig. 9.

As shown in the drawing, the 2 nd frame member 22 has a guide groove 22A formed in a portion of the side frame body 2 facing the 2 nd frame member 12. The guide groove 22A is formed continuously in the longitudinal direction of the 2 nd frame member 22 and receives the slide member 35. The slide member 35 is guided by the guide groove 22A and slides along the guide groove 22A.

The operating member 6 is movably connected to the 2 nd frame member 22, and is rotatably connected to the slide member 35 via a connecting pin 35C. The operating member 6 has a rotating portion 6A that is rotatably connected to the 2 nd frame member 22 and the slide member 35. The rotating portion 6A is a connecting projection penetrating an opening formed in the 2 nd frame member 22, and is connected to a connecting portion 35A of the slide member 35 by a connecting pin 35C. The slide member 35 slides in the guide groove 22A in conjunction with the movement of the operation member 6.

Fig. 12 is a diagram showing the operation of the operation member 6 and the slide member 35, and shows the operation member 6 and the lock mechanism 7 as viewed from the direction of arrow X5 in fig. 9 and 10.

As shown in the drawing, the operating member 6 is a rotatable operating lever and has a grip portion 6B for gripping when the latch 31 and the door and window sash 3 are operated. The rotating portion 6A of the operating member 6 protrudes from the grip portion 6B toward the slide member 35, and is attached to the support member 27 at an intermediate position between the grip portion 6B and a connecting portion 35A (connecting pin 35C) of the slide member 35. The support member 27 is fixed to the 2 nd frame member 22, and rotatably supports the rotating portion 6A of the operating member 6 via a support shaft 27A.

The operating member 6 rotates about the support shaft 27A and moves to the 1 st position P1 (see fig. 12A) or the 2 nd position P2 (see fig. 12B) (see arrow G). The 1 st position P1 is a 1 st operation position (lock position) where the latch 31 is disposed at the engagement position K1 to lock the door sash 3, and the 2 nd position P2 is a 2 nd operation position (unlock position) where the latch 31 is disposed at the non-engagement position K2 to unlock the door sash 3. When the door sash 3 is opened, the grip portion 6B is moved, and the operating member 6 is moved from the 1 st position P1 to the 2 nd position P2. The interlocking mechanism 33 moves the latch 31 from the engaging position K1 to the non-engaging position K2 in conjunction with the movement of the operating member 6 from the 1 st position P1 to the 2 nd position P2.

The grip portion 6B of the operating member 6 moves in the opening directions H1 and H2 of the door sash 3 when the operating member 6 moves from the 1 st position P1 to the 2 nd position P2, and moves in the closing directions T1 and T2 of the door sash 3 when the operating member 6 moves from the 2 nd position P2 to the 1 st position P1. Simultaneously with the movement of the grip portion 6B, the rotating portion 6A of the operating member 6 rotates.

As the operating member 6 moves from the 1 st position P1 to the 2 nd position P2, the connecting pin 35C and the connecting portion 35A of the slide member 35 are pushed toward the displacement member 36 by the rotating portion 6A that rotates. The slide member 35 slides upward toward the displacement member 36 by a force received from the operation member 6, and comes into contact with the displacement member 36. The slide member 35 presses the displacement member 36 with the contact portion 35B, and displaces the displacement member 36.

The operating member 6 is urged toward the 1 st position P1 by an urging unit (e.g., a torsion coil spring). The operating member 6 is moved from the 2 nd position P2 to the 1 st position P1 by the biasing force of the biasing means, and is disposed at the 1 st position P1. As the operating member 6 moves from the 2 nd position P2 to the 1 st position P1, the operating member 6 pulls the connecting portion 35A of the connecting pin 35C and the slide member 35 by the rotating portion 6A. The slide member 35 is pulled downward by the force received from the operation member 6, slides downward, and is separated from the displacement member 36. Further, the downward sliding of the sliding member 35 is assisted by gravity.

The displacement member 36 (see fig. 9 and 10) is connected to the 1 st frame member 21 so as to be displaceable, and is displaced in conjunction with the sliding of the slide member 35 (see arrow R). The displacement member 36 is an elongated rod-like member and is disposed along the longitudinal direction of the 1 st frame member 21. One end of the displacement member 36 is a latch portion 36A provided with the latch 31, and moves integrally with the latch 31. The other end of the displacement member 36 is a contact portion 36B that contacts the slide member 35. The contact portion 35B of the slide member 35 contacts the contact portion 36B of the displacement member 36, and the slide member 35 is interlocked with the displacement member 36.

The displacement member 36 has a rotation shaft 36C between the latch portion 36A and the contact portion 36B, and is rotated (swung) about the rotation shaft 36C to be displaced. Therefore, the displacement member 36 is a rotating member (swinging member). By the rotational displacement of the displacement member 36, the latch portion 36A and the contact portion 36B are moved in the displacement direction (rotational direction) of the displacement member 36.

Fig. 13 is a view showing the displacement member 36 provided to the 1 st frame member 21, and shows the displacement member 36 and the 1 st frame member 21 as cut along the arrow X6-X6 in fig. 9.

As shown in the figure, the 1 st frame member 21 has a receiving groove 21A formed in a portion of the side frame body 2 facing the 1 st frame member 11. The housing groove 21A is formed continuously in the longitudinal direction of the 1 st frame member 21 and houses the displacement member 36. The rotating shaft 36C of the displacement member 36 is rotatably supported by the bearing member 36D. The bearing member 36D is disposed in the housing groove 21A and fixed to the 1 st frame member 21. The displacement member 36 is displaced by rotating in the receiving groove 21A, and moves the latch 31.

Fig. 14 is a diagram showing the operation of the displacement member 36 and the latch 31, and shows the lock mechanism 7 as viewed from the direction of arrow X7 in fig. 9 and 10. Fig. 14 shows a part of the sliding member 35 on the contact portion 35B side.

As shown in the drawing, the guide member 37 is provided on the 1 st frame member 21, and is adjacent to the latch portion 36A of the displacement member 36 and the latch 31. The guide member 37 has a guide groove 37A opening toward the displacement member 36, and the displacement member 36 has a protrusion 36E disposed in the guide groove 37A. The guide member 37 guides the projection 36E formed on the latch portion 36A and the displacement member 36 in the displacement direction of the displacement member 36 through the guide groove 37A.

The displacement member 36 has a tab 36F formed at the contact portion 36B. The projecting piece 36F is a guide portion capable of guiding the contact portion 35B of the slide member 35, and projects from the contact portion 36B toward the slide member 35 side. The protruding piece 36F is disposed adjacent to the contact portion 35B of the slide member 35. The contact portion 35B of the slide member 35 is maintained at a position contactable with the contact portion 36B of the displacement member 36 by the tab 36F.

The slide member 35 slides with the projecting piece 36F of the displacement member 36 facing the contact portion 35B of the slide member 35, and the contact portion 35B of the slide member 35 moves along the projecting piece 36F. When the sliding direction of the slide member 35 is biased toward the projecting piece 36F side, the contact portion 35B of the slide member 35 may contact the projecting piece 36F. At this time, the contact portion 35B of the slide member 35 is guided to the contact portion 36B of the displacement member 36 by the protruding piece 36F, and is brought into contact with the contact portion 36B of the displacement member 36.

When the operating member 6 moves from the 1 st position P1 to the 2 nd position P2, the slide member 35 slides to displace the displacement member 36, and the displacement member 36 moves the latch 31 from the engagement position K1 to the non-engagement position K2 where the engagement with the latch holder 32 is released. At this time, the contact portion 35B of the slide member 35 comes into contact with the contact portion 36B of the displacement member 36 as the slide member 35 slides.

The contact portion 36B of the displacement member 36 is pressed in the sliding direction (here, upward) of the sliding member 35 by the contact portion 35B of the sliding member 35, and moves in the sliding direction. Thereby, the displacement member 36 is rotated and displaced, and the latch portion 36A of the displacement member 36 is moved in the opposite direction (here, downward) to the sliding direction. The displacement member 36 moves the latch 31 from the engagement position K1 to the disengagement position K2 by moving the latch portion 36A and the latch 31 in the displacement direction.

When the operating member 6 moves from the 2 nd position P2 to the 1 st position P1, the slide member 35 slides downward and is separated from the displacement member 36. At the same time, the latch 31 is moved from the non-engagement position K2 to the engagement position K1 by the biasing force of the biasing unit 34. Further, the displacement member 36 rotates and displaces, and the contact portion 36B of the displacement member 36 moves downward. In the state where the operating member 6 is disposed at the 1 st position P1, the contact portion 35B of the slide member 35 does not contact the contact portion 36B of the displacement member 36, and a gap 38 is formed between 2 contact portions 35B, 36B.

In a state where the switching of the opening and closing directions M1, M2 of the door/window sash 3 is completed by the switching mechanism 5, the door/window sash 3 is opened and closed in the opening and closing directions M1, M2 by the operation member 6 (see fig. 9 and 10). When the door sash 3 is opened, the grip 6B of the operating member 6 is pulled in the opening directions H1 and H2 of the door sash 3, and the grip 6B is moved in the opening directions H1 and H2. The operating member 6 is then moved from the 1 st position P1 to the 2 nd position P2. In conjunction with the movement of the operating member 6, the interlocking mechanism 33 moves the latch 31 to the non-engagement position K2, and releases the engagement between the latch 31 and the latch holder 32. Thereby, the latch 31 is disengaged from the latch holder 32, and the door sash 3 is unlocked. Subsequently, the grip portion 6B of the operating member 6 is pulled in the opening direction H1, H2 of the door sash 3, and the door sash 3 is moved to the open positions W1, W2. At this time, the opening angle of the door sash 3 may be limited to a prescribed opening angle by the limiting means, for example. After the door sash 3 starts moving, the operating member 6 moves from the 2 nd position P2 to the 1 st position P1, and the latch 31 moves from the non-engagement position K2 to the engagement position K1.

When the door sash 3 is closed, the grip portion 6B of the operating member 6 is pushed in the closing directions T1 and T2 (side of the side frame 2) of the door sash 3, and the door sash 3 is moved to the closing position V. At this time, the latch 31 is pushed by the latch base 32 and moves toward the non-engagement position K2. When the door sash 3 is closed, the latch 31 moves to the engagement position K1 to engage with the latch holder 32, and the door sash 3 is locked in the closed state by the latch 31.

Fig. 15 is a front view showing the switching member 4 and the switching mechanism 5 according to embodiment 1, and a part of fig. 3 is enlarged. In fig. 15, the operation member 6 and the lock mechanism 7 are omitted.

As shown in the drawing, the switching member 4 is a movable finger for operating the switching mechanism 5, and is a selecting member for selecting the opening and closing directions M1 and M2 of the door sash 3. When switching the opening/closing directions M1 and M2, the switching mechanism 5 is operated by the switching member 4 in a state where the door sash 3 is closed. The switching member 4 slides in the longitudinal direction of the 2 nd frame member 22.

The switching mechanism 5 is provided in the 1 st frame member 21, the 2 nd frame member 22, and the side frame 2, and switches the opening and closing directions M1, M2 of the door sash 3 in conjunction with the movement of the switching member 4. Further, the switching mechanism 5 includes: an interlocking portion 50 interlocking with the switching member 4, 2 protrusions 41 and 42 (a connecting protrusion 41 and a locking protrusion 42) provided on the interlocking portion 50, and a support body 43 fixed to the 3 rd frame member 13 of the side frame body 2.

The switching member 4 is attached to the interlocking portion 50. The interlocking portion 50 is provided on the 1 st frame member 21 and the 2 nd frame member 22, and is disposed along the longitudinal direction of the 1 st frame member 21 and the 2 nd frame member 22. The interlocking portion 50 is disposed between the 2 nd hinge mechanism 9 and the support 43. The connecting projection 41 is provided at one end 50A of the interlocking portion 50 on the 2 nd hinge mechanism 9 side, and the locking projection 42 is provided at the other end 50B of the interlocking portion 50 on the support body 43 side. The interlocking portion 50, the connecting projection 41, and the locking projection 42 move integrally in conjunction with the movement of the switching member 4. Thereby, the locking projection 42 is locked to the support body 43. Alternatively, the locking projection 42 and the support body 43 are unlocked.

Fig. 16 and 17 are perspective views showing the switching member 4 and the switching mechanism 5. Fig. 16 shows a state in which the locking projection 42 is locked to the support body 43, and fig. 17 shows a state in which the locking projection 42 is unlocked from the support body 43.

As shown in the drawing, the interlocking unit 50 of the switching mechanism 5 includes: a 1 st interlocking member 51 slidably provided on the 2 nd frame member 22, a 2 nd interlocking member 52 slidably provided on the 1 st frame member 21, and a corner actuator 53 provided at an upper corner portion (a corner portion between the 1 st frame member 21 and the 2 nd frame member 22) of the door sash 3. The 1 st interlocking member 51 and the 2 nd interlocking member 52 are elongated rod-like members and slide in conjunction with the operation of the switching member 4.

The 1 st interlocking member 51 is disposed along the longitudinal direction of the 2 nd frame member 22, and the 2 nd interlocking member 52 is disposed along the longitudinal direction of the 1 st frame member 21. The angular actuator 53 is a connecting mechanism that connects the 1 st interlocking member 51 and the 2 nd interlocking member 52, and is disposed between the 1 st interlocking member 51 and the 2 nd interlocking member 52. Further, the angle actuator 53 has: a tubular cover body 53A attached to the 1 st frame member 21 and the 2 nd frame member 22, and a belt-shaped slide plate 53B that slides while deforming inside the cover body 53A.

The sliding plate 53B is, for example, a flexible thin metal plate, and is attached to the one end 51A of the 1 st interlocking member 51 on the side of the angle actuator 53 and the one end 52A of the 2 nd interlocking member 52 on the side of the angle actuator 53. The 1 st interlocking member 51, the 2 nd interlocking member 52, and the slide plate 53B move integrally. By the sliding of the slide plate 53B, the angular actuator 53 moves the 1 st interlocking member 51 in interlocking with the 2 nd interlocking member 52 (see arrows F1, F2).

The locking projection 42 is a disk-shaped projection provided on the 1 st interlocking member 51, and the connecting projection 41 is a pin-shaped projection provided on the 2 nd interlocking member 52. The locking projection 42 is provided on the other end portion 51B of the 1 st interlocking member 51 opposite to the support body 43, and projects from the 1 st interlocking member 51 toward the support body 43. The connecting projection 41 is provided on the other end portion 52B of the 2 nd interlocking member 52 opposite to the 2 nd hinge mechanism 9, and projects from the 2 nd interlocking member 52 toward the 2 nd hinge mechanism 9.

The switching member 4 is attached to the 1 st interlocking member 51 and moves integrally with the 1 st interlocking member 51. As the switching member 4 moves (see arrow E), the 1 st interlocking member 51 slides in the longitudinal direction of the 2 nd frame member 22 and moves, and the locking projection 42 moves in the sliding direction of the 1 st interlocking member 51 (see arrow F1). At this time, the switching member 4, the 1 st interlocking member 51, and the locking projection 42 move in the same direction along the longitudinal direction of the 2 nd frame member 22. At the same time, the 2 nd interlocking member 52 slides in the longitudinal direction of the 1 st frame member 21 to move, and the connecting projection 41 moves in the sliding direction of the 2 nd interlocking member 52 (see arrow F2).

By moving the switching member 4, the interlocking portion 50 including the 2 interlocking members 51 and 52 moves in conjunction with the movement of the switching member 4, and the locking protrusion 42 and the connecting protrusion 41 move by the interlocking portion 50. By the operation of the switching member 4, the switching member 4 is moved to the 1 st switching position L1 (see fig. 16) or the 2 nd switching position L2 (see fig. 17) and is disposed at the 1 st switching position L1 or the 2 nd switching position L2. The 1 st switching position L1 is a position for opening and closing the door sash 3 in the 1 st opening and closing direction M1, and the 2 nd switching position L2 is a position for opening and closing the door sash 3 in the 2 nd opening and closing direction M2.

By the movement of the switching member 4, the connection protrusion 41 moves to the non-connection position N1 (see fig. 16) not connected to the 2 nd hinge mechanism 9 or the connection position N2 (see fig. 17) connected to the 2 nd hinge mechanism 9, and is disposed at the non-connection position N1 or the connection position N2. At the same time, the locking projection 42 is moved to a locking position Q1 (see fig. 16) locked to the support 43 or a non-locking position Q2 (locking release position) (see fig. 17) where the locking to the support 43 is released, and is disposed at the locking position Q1 or the non-locking position Q2.

The support body 43 has a locking hole 44 opening to the interlocking portion 50 side. When the locking protrusion 42 moves from the non-locking position Q2 to the locking position Q1, the locking protrusion 42 is inserted into the locking hole 44 and is disposed in the locking hole 44. The support 43 locks the locking projection 42 in the locking hole 44, and holds the locking projection 42 and the other end 50B of the interlocking portion 50 (the other end 51B of the 1 st interlocking member 51). When the locking protrusion 42 moves from the locking position Q1 to the non-locking position Q2, the locking protrusion 42 is pulled out from the locking hole 44, and the locking (holding) of the locking protrusion 42 is released.

Fig. 18 and 19 are diagrams illustrating operations of the switching member 4 and the switching mechanism 5. Fig. 18 shows the switching member 4 and the switching mechanism 5 as viewed from the direction of arrow X8 in fig. 16 and 17, and fig. 19 shows the switching mechanism 5 as viewed from the direction of arrow X9 in fig. 16 and 17.

As shown in the figure, when the door sash 3 is closed, the connecting projection 41 and the locking projection 42 of the switching mechanism 5 are simultaneously moved by the movement (operation) of the switching member 4, and the opening and closing directions M1 and M2 of the door sash 3 are switched.

When the door sash 3 is opened and closed in the 1 st opening and closing direction M1 (in the case of falling inward), the switching member 4 is moved from the 2 nd switching position L2 to the 1 st switching position L1 and is disposed at the 1 st switching position L1 (see fig. 18A and 19A). Thereby, the opening and closing direction of the door sash 3 is switched from the 2 nd opening and closing direction M2 to the 1 st opening and closing direction M1. At this time, the connection protrusion 41 is moved from the connection position N2 to the disconnection position N1, and is disposed at the disconnection position N1. Thereby, the connection by the connection projection 41 of the 2 nd hinge mechanism 9 is released, and the support of the 2 nd hinge mechanism 9 to the door sash 3 is released. The locking projection 42 is disposed at the locking position Q1 while moving from the non-locking position Q2 to the locking position Q1.

In the locking position Q1, the locking projection 42 is locked by the support 43 so as to be rotatable in the 1 st opening/closing direction M1 (see fig. 18A and 18B). One lower corner of the door sash 3 is supported by the 1 st hinge mechanism 8 so as to be rotatable in the 1 st opening/closing direction M1, and the other lower corner of the door sash 3 is supported by the support body 43 so as to be rotatable in the 1 st opening/closing direction M1. The door sash 3 is supported by the 1 st hinge mechanism 8 and the support 43 so as to be openable (pivotable) about the 3 rd frame member 23 in the 1 st opening/closing direction M1.

When the door sash 3 is opened and closed in the 2 nd opening and closing direction M2 (inward opening), the switching member 4 is moved from the 1 st switching position L1 to the 2 nd switching position L2 and is disposed at the 2 nd switching position L2 (see fig. 18C and 19B). Thereby, the opening and closing direction of the door sash 3 is switched from the 1 st opening and closing direction M1 to the 2 nd opening and closing direction M2. At this time, the locking projection 42 is moved from the locking position Q1 to the non-locking position Q2 and is disposed at the non-locking position Q2. Thus, the support body 43 is unlocked from the locking projection 42, and the door sash 3 can be opened and closed in the 2 nd opening and closing direction M2. The connection protrusion 41 is disposed at the connection position N2 while moving from the non-connection position N1 to the connection position N2.

When the linking projection 41 is moved to the linking position N2, the linking projection 41 links the 2 nd hinge mechanism 9, and one upper corner of the door/window sash 3 is supported by the 2 nd hinge mechanism 9 so as to be rotatable in the 2 nd opening/closing direction M2. One lower corner of the door sash 3 is supported by the 1 st hinge mechanism 8 so as to be rotatable in the 2 nd opening/closing direction M2. The door sash 3 is supported by the 1 st hinge mechanism 8 and the 2 nd hinge mechanism 9 so as to be openable (pivotable) about the 4 th frame member 24 in the 2 nd opening/closing direction M2.

Fig. 20 and 21 are perspective views showing the switching mechanism 5 and the 2 nd hinge mechanism 9 when the door sash 3 is opened. Fig. 20 shows the switching mechanism 5 and the 2 nd hinge mechanism 9 when the opening and closing direction of the door 3 is the 1 st opening and closing direction M1, and fig. 21 shows the switching mechanism 5 and the 2 nd hinge mechanism 9 when the opening and closing direction of the door 3 is the 2 nd opening and closing direction M2.

As shown in the figure, by changing the positions of the connection projection 41 of the switching mechanism 5 (the non-connection position N1, the connection position N2), the connection state of the 2 nd hinge mechanism 9 is also changed. Thereby, the operation of the 2 nd hinge mechanism 9 is changed, and the opening and closing directions M1, M2 of the door sash 3 are switched.

The 2 nd hinge mechanism 9 has: the door/window sash comprises a mounting member 60 mounted to the 1 st frame member 21 of the door/window sash 3, a base member 61 fixed to the 1 st frame member 11 of the side frame body 2, a rotating member 62 rotatably connected to the mounting member 60 and the base member 61, and a plurality of link members 71 to 74 (the 1 st link member 71, the 2 nd link member 72, the 3 rd link member 73, and the 4 th link member 74). The attachment member 60, the base member 61, the rotating member 62, and the plurality of link members 71 to 74 are rotatably connected at each connecting portion to constitute a link mechanism.

One end of the turning member 62 is rotatably connected to the base member 61 via the 1 st to 3 rd link members 71 to 73, and the other end of the turning member 62 is rotatably connected to the mounting member 60. The 1 st link member 71 and the 3 rd link member 73 are rotatably connected to the base member 61 and the rotating member 62, and the 2 nd link member 72 is rotatably connected to the base member 61 and the 3 rd link member 73. The 1 st to 3 rd link members 71 to 73 regulate the rotation angle of the rotating member 62 with respect to the base member 61. The 4 th link member 74 is rotatably connected to the mounting member 60 and the rotating member 62. The rotation angle of the mounting member 60 with respect to the rotating member 62 is limited by the 4 th link member 74.

The attachment member 60 has a long holding hole 63 for movably holding the connecting projection 41 of the switching mechanism 5. The connection projection 41 moves in the longitudinal direction of the long holding hole 63 in the long holding hole 63, and is disposed at the non-connection position N1 or the connection position N2. The rotating member 62 has: a locking long hole 64 for movably locking the linking protrusion 41, and a passing portion 65 connected to the locking long hole 64. The passage portion 65 is formed from the middle portion in the longitudinal direction of the locking long hole 64 toward the indoor side. The linking projection 41 moves in the locking long hole 64 in the longitudinal direction of the locking long hole 64, and is disposed at the non-linking position N1 or the linking position N2. At the connection position N2, the connection projection 41 in the locking long hole 64 is locked by the turning member 62, and the turning member 62 and the attachment member 60 are connected by the connection projection 41.

Fig. 22 to 24 are views showing the switching mechanism 5 and the 2 nd hinge mechanism 9 when the opening and closing direction of the door sash 3 is the 1 st opening and closing direction M1. Fig. 22 and 23 show the switching mechanism 5 and the 2 nd hinge mechanism 9 when the door sash 3 is closed, and fig. 24 shows the 2 nd hinge mechanism 9 when the door sash 3 is opened. Fig. 22 and 24 are plan views of the switching mechanism 5 and the 2 nd hinge mechanism 9 corresponding to fig. 5, and fig. 23 is a front view of the switching mechanism 5 and the 2 nd hinge mechanism 9 corresponding to fig. 3.

As shown in the drawing, when the door sash 3 is closed, the 2 nd hinge mechanism 9, the 2 nd interlocking member 52 of the interlocking portion 50, and the connecting projection 41 are disposed between the 1 st frame member 11 and the 1 st frame member 21. In this state, the connection protrusion 41 moves to the non-connection position N1 or the connection position N2 within the holding long hole 63 and the locking long hole 64 in accordance with the movement of the switching member 4, and is disposed at the non-connection position N1 or the connection position N2. When the door sash 3 is opened and closed in the 1 st opening and closing direction M1 (when the door sash is tilted inward), the switching member 4 is disposed at the 1 st switching position L1, and the linking protrusion 41 is disposed at the non-linking position N1. Thus, the connecting projection 41 is disposed in a position where it can pass through the passage portion 65 in the locking long hole 64. As a result, the coupling protrusion 41 is not locked by the turning member 62, and the coupling of the turning member 62 and the mounting member 60 by the coupling protrusion 41 is released.

When the door sash 3 is opened by the operating member 6, the connecting projection 41 passes through the passing portion 65 and is disengaged from the rotating member 62 (see arrow Z of fig. 24). Further, the rotating member 62 rotates relative to the base member 61, and the mounting member 60 rotates relative to the rotating member 62. Thus, the door sash 3 is opened in the 1 st opening direction H1 (see fig. 1) with the 1 st frame member 21 being parallel to the 1 st frame member 11. At this time, the 2 nd hinge mechanism 9 restricts the opening angle of the door 3 by restricting the rotation angle of the rotation member 62 and the rotation angle of the attachment member 60, and holds the door 3 at a predetermined opening angle. When the door sash 3 is closed by the operating member 6, the linking projection 41 passes through the passage portion 65 and returns to the non-linking position N1 in the locking elongated hole 64.

Fig. 25 to 27 are views showing the switching mechanism 5 and the 2 nd hinge mechanism 9 when the opening and closing direction of the door sash 3 is the 2 nd opening and closing direction M2. Fig. 25 and 26 are views showing the switching mechanism 5 and the 2 nd hinge mechanism 9 when the door sash 3 is closed, and fig. 27 is a view showing the 2 nd hinge mechanism 9 when the door sash 3 is opened. Fig. 25 and 27 are plan views of the switching mechanism 5 and the 2 nd hinge mechanism 9 corresponding to fig. 5, and fig. 26 is a front view of the switching mechanism 5 and the 2 nd hinge mechanism 9 corresponding to fig. 3.

When the door sash 3 is opened and closed in the 2 nd opening and closing direction M2 (inward opening), the switching member 4 is disposed at the 2 nd switching position L2, and the linking protrusion 41 is disposed at the linking position N2. Thereby, the connecting projection 41 is disposed at a position locked to the turning member 62 in the locking long hole 64, and connects the turning member 62 and the attachment member 60. When the door sash 3 is opened by the operating member 6, the rotating member 62 rotates integrally with the mounting member 60, and the door sash 3 is opened in the 2 nd opening direction H2 (see fig. 2). At this time, the 2 nd hinge mechanism 9 restricts the opening angle of the door 3 by restricting the rotation angle of the rotation member 62, and holds the door 3 at a predetermined opening angle.

In the door 1A described above, the opening and closing directions M1, M2 of the door sash 3 are switched by operating the switching mechanism 5 with the switching member 4 different from the operating member 6. Therefore, the opening and closing directions M1, M2 of the door sash 3 can be easily switched, and the opening and closing directions M1, M2 of the door sash 3 can be easily determined. In all the opening and closing directions M1 and M2, the door/window sash 3 can be opened and closed by the same operation using 1 operation member 6. As a result, the door/window sash 3 can be easily opened and closed in the respective opening and closing directions M1 and M2.

By providing the switching member 4 and the operating member 6 in the same frame member of the door sash 3, the positions of the switching member 4 and the operating member 6 can be easily grasped. Further, when the switching member 4 and the operating member 6 are continuously operated, the switching member 4 and the operating member 6 can be smoothly operated. By arranging the switching mechanism 5 and the lock mechanism 7 in parallel to the same frame member in the door sash 3, an increase in the arrangement space of the switching mechanism 5 and the lock mechanism 7 can be suppressed.

Since the lock mechanism 7 is the latch device 30, the door sash 3 can be reliably locked to the side frame body 2 by the lock mechanism 7 having a simple structure. Further, the lock mechanism 7 can be easily operated by the operation member 6. The interlocking mechanism 33 of the lock mechanism 7 interlocks the latch 31 with the operating member 6 through 2 members, i.e., the slide member 35 and the displacement member 36. Therefore, the lock latch 31 can be reliably interlocked with the operating member 6 while suppressing the structure of the interlocking mechanism 33 from becoming complicated.

The latch 31 and the operating member 6 are provided on different frame members (1 st frame member 21, 2 nd frame member 22) and are disposed on different edge portions (1 st edge portion 3A, 2 nd edge portion 3B) of the door sash 3. Here, the 1 st frame member 21 is an upper frame member provided with the latch 31, and the 2 nd frame member 22 is a vertical frame member provided with the operation member 6. Therefore, the latch 31 can be easily operated by the operating member 6 at a position lower than the 1 st frame member 21. Thus, the latch 31 can be operated on the 2 nd frame member 22 located at a position where the operation is easier than that of the 1 st frame member 21 provided with the latch 31, and the opening and closing operation of the door sash 3 can be easily performed.

When the door sash 3 is opened, the grip portion 6B of the operating member 6 is moved in the opening direction H1, H2 of the door sash 3, and the latch 31 is moved to the non-engagement position K2. Therefore, after the engagement between the latch 31 and the latch holder 32 is released, the door sash 3 can be smoothly moved in the opening directions H1 and H2 by the operating member 6. The operation of opening the door sash 3 is simplified, and the door sash 3 can be easily and smoothly opened. Further, only by closing the door sash 3, the latch 31 can be engaged with the latch holder 32 to lock the door sash 3.

By housing the slide member 35 and the displacement member 36 in the grooves (the guide groove 22A and the housing groove 21A) of the frame 20, the appearance of the door sash 3 can be improved. The displacement member 36 can be accurately displaced by the guide of the guide member 37, and the movement of the latch 31 can be stabilized.

Since the displacement member 36 is a rotating member that rotates about the rotating shaft 36C, the latch 31 provided in the latch portion 36A can be accurately moved. Even if the distance between the latch 31 and the slide member 35 becomes long, the latch 31 can be reliably moved by the rotational displacement of the displacement member 36. By changing the length of the displacement member 36 (the distance between the latch portion 36A and the contact portion 36B), it is possible to easily cope with the change in the position of the latch 31, and to provide the latch 31 to the 1 st frame member 21 of various lengths.

The center of gravity of the displacement member 36 may coincide with the axial center of the rotating shaft 36C or may be offset from the axial center of the rotating shaft 36C. In contrast, the center of gravity of the displacement member 36 may be located closer to the latch portion 36A than the rotation shaft 36C, or closer to the contact portion 36B than the rotation shaft 36C. When the center of gravity of the displacement member 36 is located closer to the contact portion 36B than the pivot shaft 36C, the balance between the latch 31 and the displacement member 36 is adjusted, and the latch 31 can be easily moved from the non-engagement position K2 to the engagement position K1. When the contact portion 36B of the displacement member 36 moves downward due to gravity, the latch 31 can be biased toward the engagement position K1 by the gravity that moves the contact portion 36B. By using the center of gravity of the displacement member 36 in this way, the latch 31 can be easily moved (returned) to the engagement position K1. The force that urges the latch 31 is adjusted by positioning the center of gravity of the displacement member 36 between the rotation shaft 36C and the contact portion 36B.

The latch 31 can be reliably moved (returned) to the engagement position K1 by the biasing means 34. Further, the state in which the latch 31 is engaged with the latch holder 32 can be reliably maintained by the biasing force of the biasing unit 34. When the lock bar 31 moves, the movement of the lock bar 31 can be assisted by using the center of gravity of the displacement member 36. In contrast, when the latch 31 moves to the engagement position K1, the center of gravity of at least one of the biasing unit 34 and the displacement member 36 can be used. That is, the center of gravity of both the urging unit 34 and the displacement member 36 may be used, or only the center of gravity of the urging unit 34 or only the center of gravity of the displacement member 36 may be used.

The lock mechanism 7 is not limited to the latch device 30, and may be another lock mechanism capable of locking the door sash 3 to the side frame 2. Further, the latch 31 may be formed integrally with the latch portion 36A of the displacement member 36. In contrast, the latch 31 may be a different member from the displacement member 36. In this case, the latch 31 is attached to the latch portion 36A of the displacement member 36 and held by the displacement member 36.

Here, the latch 31 is provided on the upper frame member, and the operation member 6 and the switching member 4 are provided on the vertical frame member. On the other hand, the lock bar 31 may be provided to the vertical frame member or the lower frame member in accordance with the opening mode of the door sash 3 or the like. In this case, the 1 st frame member 21 is a vertical frame member or a lower frame member. The operation member 6 and the switching member 4 are provided on a 2 nd frame member 22 (an upper frame member, a lower frame member, or a vertical frame member) different from the 1 st frame member 21. The frame member located at a position easier to handle than the 1 st frame member 21 is set as the 2 nd frame member 22 based on the installation conditions of the door/window 1A (for example, the positions of the 1 st frame member 21 and the other frame members 22 to 24). The 1 st frame member 21 and the 2 nd frame member 22 may be frame members whose ends are connected to each other, or may be frame members facing each other.

Embodiment 2

Next, the door and window of embodiment 2 will be explained. Hereinafter, the description of the same items as those of the door/window 1A of embodiment 1 will be omitted, and the description of different items from the door/window 1A of embodiment 1 will be given. In the door/window according to embodiment 2, the same names and symbols as those used for the structure of the door/window 1A according to embodiment 1 are used for the structure corresponding to the structure of the door/window 1A according to embodiment 1.

Fig. 28 is a front view showing the structure of the door/window 1B according to embodiment 2, and shows the door/window 1B as viewed from the indoor side, similarly to fig. 3. In fig. 28, a part of the frame body 20 is schematically shown by a two-dot chain line to show the internal structure of the door window 1B.

As shown in the drawing, the door window 1B of embodiment 2, which is different from the door window 1A of embodiment 1, has the following structure: the switching member 4, the switching mechanism 5, and the 2 nd hinge mechanism 9 of the opening/closing mechanism 40. Other structures of the door/window 1A according to embodiment 1 are the same as those of the door/window 1B according to embodiment 2.

In the housing 20 of the door sash 3, the switching member 4 and the operating member 6 are provided in different frame members, and the switching mechanism 5 and the lock mechanism 7 are provided in different frame members. Here, the switching member 4 is provided on the 3 rd frame member 23, and the operating member 6 is provided on the 2 nd frame member 22. The switching member 4 slides in the longitudinal direction of the 3 rd frame member 23. The switching mechanism 5 is provided in the 3 rd frame member 23 and the 4 th frame member 24, and the lock mechanism 7 is provided in the 1 st frame member 21 and the 2 nd frame member 22.

Fig. 29 and 30 are perspective views showing the switching member 4 and the switching mechanism 5. Fig. 29 shows a state in which the locking projection 42 is locked to the support body 43, and fig. 30 shows a state in which the locking projection 42 is unlocked from the support body 43. Fig. 31 is a front view showing a part of the switching mechanism 5 on the support 43 side. Fig. 31A shows the locking projection 42 and the support 43 as viewed from the direction of arrow Y1 in fig. 29, and fig. 31B shows the locking projection 42 and the support 43 as viewed from the direction of arrow Y2 in fig. 30.

As shown in the figure, the switching mechanism 5 includes: the connecting member 45 and the locking projection 42 provided in the interlocking portion 50. The interlocking portion 50 is provided on the 3 rd frame member 23 and the 4 th frame member 24, and is disposed along the longitudinal direction of the 3 rd frame member 23 and the 4 th frame member 24. The link member 45 is provided at one end 50A of the interlocking portion 50 on the 2 nd hinge mechanism 9 side. The interlocking portion 50, the link member 45, and the locking projection 42 move integrally in conjunction with the movement of the switching member 4.

In the interlocking section 50 of the door/window 1B, the 1 st interlocking member 51 is disposed along the longitudinal direction of the 3 rd frame member 23 and slidably provided in the 3 rd frame member 23. The 2 nd interlocking member 52 is disposed along the longitudinal direction of the 4 th frame member 24, and is slidably provided on the 4 th frame member 24. The angle actuator 53 is provided at a lower corner portion of the door sash 3 (a corner portion between the 3 rd frame member 23 and the 4 th frame member 24), and a cover 53A of the angle actuator 53 is attached to the 3 rd frame member 23 and the 4 th frame member 24.

The locking projection 42 is a columnar projection provided on the 1 st interlocking member 51, and the link member 45 is a plate-shaped protrusion (link plate) provided on the 2 nd interlocking member 52. The link member 45 is provided at the other end 52B of the 2 nd interlocking member 52, and protrudes from the 2 nd interlocking member 52 toward the 2 nd hinge mechanism 9. As the switching member 4 moves (see arrow E), the 1 st interlocking member 51 slides in the longitudinal direction of the 3 rd frame member 23 and moves, and the locking projection 42 moves in the sliding direction of the 1 st interlocking member 51 (see arrow F1). At this time, the switching member 4, the 1 st interlocking member 51, and the locking projection 42 move in the same direction along the longitudinal direction of the 3 rd frame member 23. At the same time, the 2 nd interlocking member 52 slides in the longitudinal direction of the 4 th frame member 24 to move, and the connecting member 45 moves in the sliding direction of the 2 nd interlocking member 52 (see arrow F2).

By moving the switching member 4, the locking projection 42 and the link member 45 are moved by the interlocking portion 50. The connection member 45 is moved to the non-connection position N1 (see fig. 29) or the connection position N2 (see fig. 30), and is disposed at the non-connection position N1 or the connection position N2. At the same time, the locking projection 42 moves to the locking position Q1 (see fig. 29 and 31A) or the non-locking position Q2 (see fig. 30 and 31B), and is disposed at the locking position Q1 or the non-locking position Q2. The support body 43 has a locking groove 46 capable of accommodating the locking projection 42. The locking groove 46 is formed along the longitudinal direction of the 3 rd frame member 23 (the sliding direction F1 of the 1 st interlocking member 51), and opens toward the interlocking portion 50.

When the locking projection 42 moves from the non-locking position Q2 to the locking position Q1, the locking projection 42 is inserted into the locking groove 46 and is disposed in the locking groove 46. The support 43 locks the locking projection 42 in the locking groove 46, and holds the locking projection 42 and the other end portion 50B of the interlocking portion 50 (the other end portion 51B of the 1 st interlocking member 51). When the locking projection 42 moves from the locking position Q1 to the non-locking position Q2, the locking projection 42 is pulled out from the locking groove 46, and the locking (holding) of the locking projection 42 is released. When the door sash 3 is closed, the link member 45 of the switching mechanism 5 moves together with the locking projection 42 by the movement (operation) of the switching member 4, and the opening and closing directions M1 and M2 of the door sash 3 are switched.

When the door sash 3 is opened and closed in the 1 st opening and closing direction M1 (in the case of falling inward), the switching member 4 is moved from the 2 nd switching position L2 to the 1 st switching position L1 and is disposed at the 1 st switching position L1 (see fig. 29). At the same time, the link member 45 is moved from the link position N2 to the non-link position N1 and is disposed at the non-link position N1. Thereby, the connection by the connection member 45 of the 2 nd hinge mechanism 9 is released, and the support of the door sash 3 by the 2 nd hinge mechanism 9 is released. The locking projection 42 is disposed at the locking position Q1 while moving from the non-locking position Q2 to the locking position Q1. In the locking position Q1, the locking projection 42 is locked by the support 43 so as to be rotatable in the 1 st opening/closing direction M1.

When the door sash 3 is opened and closed in the 2 nd opening and closing direction M2 (inward opening), the switching member 4 is moved from the 1 st switching position L1 to the 2 nd switching position L2 and is disposed at the 2 nd switching position L2 (see fig. 30). At the same time, the locking projection 42 is moved from the locking position Q1 to the non-locking position Q2 and is disposed at the non-locking position Q2. Thus, the support body 43 releases the locking of the locking projection 42, and the door sash 3 can be opened and closed in the 2 nd opening and closing direction M2. The link member 45 is disposed at the connection position N2 while moving from the non-connection position N1 to the connection position N2. When the link member 45 is moved to the link position N2, the link member 45 is connected to the 2 nd hinge mechanism 9, and one upper corner portion of the door/window 3 is supported by the 2 nd hinge mechanism 9 so as to be rotatable in the 2 nd opening/closing direction M2.

Fig. 32 and 33 are views showing the switching mechanism 5 and the 2 nd hinge mechanism 9 when the opening and closing direction of the door sash 3 is the 1 st opening and closing direction M1, and fig. 34 and 35 are views showing the switching mechanism 5 and the 2 nd hinge mechanism 9 when the opening and closing direction of the door sash 3 is the 2 nd opening and closing direction M2. Fig. 32A is a side view as viewed from the direction of arrow Y3 in fig. 29, and fig. 34A is a side view as viewed from the direction of arrow Y4 in fig. 30. Fig. 32B and 34B are perspective views of the door sash 3 when closed, and fig. 33 and 35 are perspective views of the door sash 3 when opened. Fig. 32 to 35 schematically show the door sash 3 by a two-dot chain line.

As shown in the drawing, in the door/window 1B, the 2 nd hinge mechanism 9 does not have the 2 nd link member 72. One end of the rotating member 62 is rotatably connected to the base member 61 via 2 link members (the 1 st link member 71 and the 3 rd link member 73). The mounting member 60 does not have the long holding hole 63, and the pivoting member 62 does not have the long locking hole 64 and the passing portion 65. The link member 45 of the switching mechanism 5 has a locking recess 47 that opens toward the 2 nd hinge mechanism 9, and the rotation member 62 of the 2 nd hinge mechanism 9 has a locking piece 66 that protrudes toward the link member 45. The locking piece 66 is a bent portion formed by bending a part of the rotating member 62, and is formed at an end of the rotating member 62 on the side of the connecting member 45.

When the door sash 3 is closed, the 2 nd hinge mechanism 9 is disposed between the 1 st frame member 11 and the 1 st frame member 21. In this state, the link member 45 moves to the non-connection position N1 or the connection position N2 and is disposed at the non-connection position N1 or the connection position N2 in accordance with the movement of the switching member 4. When the link member 45 moves from the non-link position N1 to the link position N2, the locking recess 47 of the link member 45 moves toward the locking piece 66 of the rotating member 62, and the locking piece 66 is inserted into the locking recess 47. When the link member 45 is disposed at the link position N2 (see fig. 34 and 35), the locking piece 66 is disposed in the locking recess 47, and the locking piece 66 and the rotating member 62 are locked by the link member 45. The rotating member 62 is connected to the door and window sash 3 through the connecting member 45. Since the link member 45 only locks the locking piece 66 of the pivoting member 62, resistance when the link member 45 is moved by the switching member 4 is reduced, and the switching member 4 and the link member 45 are easily moved.

When the link member 45 moves from the connecting position N2 to the non-connecting position N1, the locking recess 47 of the link member 45 is separated from the locking piece 66 of the rotating member 62. When the link member 45 is disposed at the non-link position N1 (see fig. 32 and 33), the locking piece 66 is disposed so as to be disengaged from the locking recess 47, and the locking of the locking piece 66 and the rotating member 62 by the link member 45 is released. At the same time, the connection of the rotating member 62 to the door and window sash 3 through the connecting member 45 is released. The locking recess 47 and the locking piece 66 are disposed opposite to each other in a state of being separated in the longitudinal direction of the 4 th frame member 24.

When the door sash 3 is opened and closed (tilted inward) in the 1 st opening and closing direction M1 (see fig. 32 and 33), the switching member 4 is disposed at the 1 st switching position L1, and the link member 45 is disposed at the non-link position N1. Thereby, the connection between the rotating member 62 and the door sash 3 is released. When the door sash 3 is opened by the operating member 6, the rotating member 62 rotates relative to the base member 61, and the mounting member 60 rotates relative to the rotating member 62. Thereby, the door sash 3 is opened in the 1 st opening direction H1 (see fig. 1).

When the door sash 3 is opened and closed (opened inward) in the 2 nd opening and closing direction M2 (see fig. 34 and 35), the switching member 4 is disposed at the 2 nd switching position L2, and the link member 45 is disposed at the connection position N2. Thereby, the rotating member 62 is connected to the door sash 3. When the door sash 3 is opened by the operating member 6, the pivot member 62 and the mounting member 60 pivot integrally with the door sash 3, and the door sash 3 is opened in the 2 nd opening direction H2 (see fig. 2).

In the door window 1B described above, the switching mechanism 5 and the lock mechanism 7 are provided in different frame members in the frame 20 of the door sash 3. Therefore, the switching mechanism 5 and the lock mechanism 7 can be easily disposed in the housing 20. Further, the shapes of the switching mechanism 5 and the lock mechanism 7 and the arrangement structure of the switching mechanism 5 and the lock mechanism 7 can be simplified.

Although the present invention has been described above as applied to an inwardly-opening and inwardly-tilting window, the present invention may be applied to windows other than inwardly-opening and inwardly-tilting windows. The present invention can be applied to various doors and windows (windows, doors, etc.) capable of switching the opening and closing directions of the door and window sections 3. Further, marks (characters, symbols, pictures, characters, figures, and the like) indicating the opening and closing directions M1 and M2 of the door sash 3 may be provided at the switching positions L1 and L2 of the switching member 4, or the marks indicating the opening and closing directions M1 and M2 of the door sash 3 may be changed according to the movement of the switching member 4. In this way, the opening and closing directions M1 and M2 of the door sash 3 can be determined more easily.
