Patent document 1: japanese patent laid-open publication No. 2017-203341.

Disclosure of Invention

In addition, in the case of the above-described door window, for example, when an opening for allowing a person to enter or exit is provided, since the inner peripheral fin portion protruding from the lower frame is uneven, the installation place is undesirably limited in consideration of the "barrier-free design". Although countermeasures such as providing inclined surfaces on both sides of the inner peripheral fin portion may be taken, a space for disposing the inclined surfaces is required on both the entrance side and the exit side of the door window, and there is a possibility that the installation place is more restricted.

In view of the above circumstances, the present invention aims to provide a door/window attachment device and a door/window that can realize a door/window structure that can ensure water tightness without significantly limiting the installation location.

In order to achieve the above object, a door/window attachment device according to the present invention is a door/window attachment device in which a door/window sash is provided with an operating member that operates in response to an operation of a handle, and the door/window sash is openable together with the door/window sash about an opening axis in a vertical direction with respect to a side frame body when the operating member is moved from a lock position to an open position, the door/window attachment device including: a device body mounted to a lower frame of the door and window sash; an input member that is disposed so as to be movable relative to the apparatus main body and is connected to the operating member; a watertight holding member which is disposed in the device body in a state of being movable in a vertical direction of the door/window sash; and a connection mechanism that connects the input member and the watertight holding member and moves the watertight holding member relative to the apparatus main body by an operation of the input member, wherein the connection mechanism lowers the watertight holding member when the operation member is arranged at the lock position and raises the watertight holding member when the operation member is arranged at the open position.

According to the present invention, the watertight holding member is provided in the device body attached to the lower frame so as to be movable in the vertical direction, and when the operating member is disposed in the lock position, that is, when the door/window sash is closed, the watertight holding member can be lowered and brought into pressure contact with the lower frame, and when the operating member is disposed in the open position, that is, when the door/window sash is opened and moved, the watertight holding member is raised, so that it is possible to ensure the required watertightness between the door/window sash and the side frame body when the door/window sash is closed, without providing a protrusion such as an inner peripheral fin in the lower frame. Therefore, the present invention can be applied to buildings and the like in consideration of "barrier-free design" without limiting the installation places of the doors and windows.

Detailed Description

Hereinafter, preferred embodiments of the accessory device for doors and windows according to the present invention will be described in detail with reference to the accompanying drawings. For convenience, the following description will be made using terms "depth direction" and "front view direction". The "depth direction" refers to a direction along the depth of the door/window as indicated by an arrow a in the drawing. The surface along the depth direction is sometimes referred to as a "depth surface". The "front view direction" refers to a direction extending vertically perpendicular to the depth direction if the member extends in the horizontal direction, such as an upper frame or an upper frame described below. In the case of a member extending in the vertical direction such as a vertical frame or a vertical frame, a horizontal direction perpendicular to the depth direction is referred to as a "front view direction". The surface along the main viewing surface direction is sometimes referred to as a "main viewing surface".

Fig. 1 to 3 show a window and door to which an accessory device for a window and door according to an embodiment of the present invention is applied. The door window exemplified here includes a side frame 10 and a door sash 20, and the door sash 20 is supported to be openable and closable with respect to the side frame 10 by a lower support unit 1 and an upper support unit 2 provided between the side frame 10 and the door sash 20.

The side frame 10 is configured by combining an upper frame 11, a lower frame 12, and right and left vertical frames 13 and 14 into four frames. In the present embodiment, in particular, frames having the same cross-sectional shape are used as the upper frame 11 and the left and right vertical frames 13 and 14, and the respective end portions are connected by a miter joint. The upper frame 11 and the left and right vertical frames 13 and 14 are resin-molded extruded members, and have a substantially uniform cross-sectional shape along the entire length in the longitudinal direction. As is clear from the figure, the upper frame 11 and the left and right vertical frames 13 and 14 are provided with inner peripheral fins 11b, 13b, and 14b at the edge portions of the inner peripheral deep surfaces 11a, 13a, and 14a located outside the room. The inner peripheral fins 11b, 13b, and 14b protrude toward the inner peripheral side, and have sealing members 15 at their edge portions facing the inside of the room.

On the other hand, the lower frame 12 of the side frame 10 is configured such that the dimension in the depth direction matches the upper frame 11 and the like, but does not have a protruding portion such as an inner peripheral fin portion, and the inner peripheral side deep surface 12a is substantially flat. In the illustrated example, the lower frame 12 having the drain passage 12b therein is illustrated. The drainage path 12b is configured to have a slit-shaped opening in the depth surface of the lower frame 12, and to drain water that has permeated through the slit-shaped opening to the outside of the lower frame 12 from a drainage port (not shown). The lower frame 12 is also an extruded profile molded from resin.

The door sash 20 is configured by attaching an upper frame 22, a lower frame 23, and left and right vertical frames 24 and 25 to the periphery of a rectangular surface member 21. In the present embodiment, frames having the same cross-sectional shape on all sides are used as the frames 22, 23, 24, and 25 constituting the door sash 20, and the end portions thereof are joined by miter joint. These frames 22, 23, 24, and 25 are extruded members molded from resin, and each have a substantially uniform cross-sectional shape along the entire length in the longitudinal direction. As is clear from the figure, in each of the frames 22, 23, 24, and 25, outer peripheral fins 22b, 23b, 24b, and 25b are provided at the edge portions of the outer peripheral side depth surfaces 22a, 23a, 24a, and 25a located on the indoor side. The outer peripheral fins 22b, 23b, 24b, 25b project toward the outer peripheral side, and have sealing members 26 at their edge portions facing the outside. On the other hand, the inner peripheral deep surfaces 22c, 23c, 24c, and 25c of the frames 22, 23, 24, and 25 have support fins 22d, 23d, 24d, and 25d at their edge portions located outside the room, and have beads 27 attached to their edge portions located inside the room. The support fins 22d, 23d, 24d, and 25d protrude toward the inner peripheral side and support the surface of the face material 21 facing the outside. The bead 27 is used to support the interior facing surface of the facestock 21. For convenience, the right and left vertical frames 13 and 14 and the left and right vertical frames 24 and 25 are referred to as a right vertical frame 13 and a right vertical frame 24 on the right side and a left vertical frame 14 and a left vertical frame 25 on the left side, respectively, when viewed from the indoor side.

The lower support unit 1 and the upper support unit 2 constitute a window known as an inwardly-opened and inwardly-tilted window, and are provided between the left vertical side frame 14 and the left vertical frame 25. As schematically shown in fig. 4A to 4C, the lower support unit 1 supports the door sash 20 so as to be openable (inwardly opened) with respect to the side frame body 10 about an opening axis C1 in the vertical direction so that the right vertical frame 24 protrudes toward the indoor side, and so as to be openable (inwardly opened) with respect to a tilting axis C2 in the longitudinal direction of the lower frame 23 so that the upper frame 22 protrudes toward the indoor side. The upper support unit 2 is switched between a locked state and an unlocked state by the operation of an operating member 3 described below. When the upper support unit 2 is in the locked state, the upper frame 22 can rotate about the opening axis C1 with respect to the side frame body 10. When the upper support unit 2 is in the unlocked state, the upper frame 22 can move indoors while maintaining a substantially parallel state with respect to the upper frame 11.

As shown in fig. 1 to 3, the door sash 20 is provided with a handle 4 on a right vertical frame 24, and an operating member 3 is disposed on a portion of the door sash 20 that is a peripheral edge thereof. The handle 4 is attached to a front view surface facing the inside of the room as a part that is operated when opening and closing the door and window sash 20. The handle 4 is rotatable about a handle axis in the depth direction. In the present embodiment, the position extending substantially vertically downward from the axis of the handle is the locked position, the position extending substantially horizontally by rotating 90 ° counterclockwise from the locked position is the inward opening position, and the position extending substantially vertically upward by further rotating 90 ° counterclockwise from the inward opening position is the inward tilting position, and the operation can be performed from the locked position to the inward tilting position.

The operating member 3 is a belt-like member, and is disposed so as to be able to advance and retreat in the housing grooves 22e, 23e, 24e, and 25e formed in the outer peripheral side deep surface of the frames 22, 23, 24, and 25 in the longitudinal direction. In the present embodiment, the upper frame 22, the right vertical frame 24, and the lower frame 23 are connected in series, and are arranged to advance and retreat in conjunction with the operation of the handle 4. More specifically, as the handle 4 is rotated counterclockwise from the locked position to the retracted position, the operating member 3 of the right vertical frame 24 moves downward, the operating member 3 of the upper frame 22 moves rightward, and the operating member 3 of the lower frame 23 moves leftward. The upper support unit 2 is maintained in the locked state by moving the operating member 3 to the right side in accordance with the operation of the handle 4 from the locked position to the inward opening position. That is, the upper support unit 2 functions such that the upper frame 22 can only rotate about the opening axial center C1 in the vertical direction with respect to the upper frame 11, and the upper frame 22 cannot move parallel to the upper frame 11. On the other hand, when the handle 4 is operated to the retracted position and the amount of movement of the operating member 3 to the right side increases, the upper support unit 2 is in the unlocked state. Thereby, the upper support unit 2 functions to allow the upper frame 22 to move parallel to the upper frame 11.

Although not explicitly shown in the drawings, the operating member 3 disposed on the right vertical frame 24 is provided with a lock pin at an appropriate position. When the handle 4 is disposed at the locked position, the lock pin and a stopper projection (not shown) provided on the right vertical frame 13 are provided in parallel in the depth direction on the indoor side, and abut against each other to prevent the door sash 20 from opening with respect to the side frame 10. On the other hand, when the handle 4 is disposed at the inward opening position and the inward tilting position, the lock pin moves to a position below the stopper projection, and the door sash 20 can be opened with respect to the side frame 10.

On the other hand, as shown in fig. 2, the operating member 3 disposed on the lower frame 23 is provided with a connecting pin (operating member) 5. The connecting pin 5 is fixed to the operating member 3 in a state where its tip portion having a small diameter projects outward from the receiving groove 23e of the lower frame 23, and is movable integrally with the operating member 3. When the position of the operating member 3 when the handle 4 is disposed at the locked position is defined as the locked position, the position of the operating member 3 when the handle 4 is disposed at the inward opening position is defined as the open position, and the position of the operating member 3 when the handle 4 is disposed at the inward tilting position is defined as the tilting position, the connecting pin 5 gradually moves to the left side with respect to the lower frame 23 as the operating member 3 moves to the locked position, the open position, and the tilting position as viewed from the indoor side.

As is clear from fig. 2 and 3, the door sash 20 is supported by the side frame body 10 via the lower support unit 1 and the upper support unit 2 between the upper frame 11 and the left and right vertical frames 13 and 14 of the side frame body 10 and the upper frame 22 and the left and right vertical frames 24 and 25 of the door sash 20 such that the seal member 15 attached to the inner peripheral fins 11b, 13b and 14b can be brought into contact with the door sash 20 and the seal member 26 attached to the outer peripheral fins 22b, 24b and 25b can be brought into contact with the side frame body 10, whereby the door sash 20 can be secured with a required water-tightness when closed with respect to the side frame body 10. In contrast, the vertical dimension of the door sash 20 between the lower frame 12 and the lower frame 23 is smaller than the vertical dimension of the side frame body 10, so that the attachment device 30 can be disposed between the inner peripheral side deep surface 12a of the lower frame 12 and the outer peripheral side deep surface 23a of the lower frame 23 in a state of facing each other with a gap when the door sash 20 is closed with respect to the side frame body 10.

The accessory device 30 includes a device body 31, and the device body 31 has a size that can fill a gap between the lower frame 12 and the lower frame 23. As shown in fig. 5 and 6, the device main body 31 is a member solid in the middle, and is attached to the lower surface of the lower frame 23 via a hinge 40, wherein a front view surface 31a facing the inside of the room and a front view surface 31b facing the outside of the room are parallel to each other, and a portion thereof located outside the room protrudes upward and downward. The hinge 40 includes a tilt shaft 41 extending substantially horizontally in the longitudinal direction of the lower frame 23, and connects the lower frame 23 and the device body 31 to each other in a rotatable state about the axis center (i.e., a tilt axis center C2) of the tilt shaft 41. More specifically, one element 42 of the hinge 40 is fixed to the outer peripheral fin portion 23b of the lower frame 23, the other element 43 of the hinge 40 is fixed to the main viewing surface 31a of the device body 31 facing the indoor space, and the lower frame 23 and the device body 31 are rotatably connected to each other on the outer peripheral side of the outer peripheral fin portion 23b in a state where the tilt shaft 41 is located on the indoor side of the device body 31.

As is clear from the figure, when the main viewing surface 31a of the device main body 31 facing the interior of the room is disposed in the vertical direction (this state is hereinafter referred to as a standard position of the device main body 31), the upper edge portion thereof comes into pressure contact with the sealing member 26 attached to the outer peripheral fin portion 23b of the lower frame 23. The main viewing surface 31b facing the outside of the room of the apparatus main body 31 placed at the standard position is placed on substantially the same plane as the main viewing surface 23f facing the outside of the room of the support fin 23d of the lower frame 23. Fin seal members 32 are attached to the inner peripheral side deep surface 31c and the outer peripheral side deep surface 31d, respectively, of the device body 31 at the portion located outside the chamber. When the device body 31 is disposed at the standard position, the fin seal member 32 attached to the inner circumferential deep surface 31c is in contact with the outer circumferential deep surface 23g of the support fin 23d provided in the lower frame 23. The fin seal member 32 attached to the outer peripheral side deep surface 31d can be brought into contact with the inner peripheral side deep surface 12a of the lower frame 12 when the device body 31 is disposed at the standard position in the state where the door sash 20 is closed with respect to the side frame 10.

As shown in fig. 2, in the apparatus main body 31, an upper slider 33 is disposed in a region facing the operating member 3 of the lower frame 23, and a lower slider 34 is disposed in a portion vertically below the upper slider 33. As shown in fig. 5, 6, 7A to 7B, and 11, the upper slider 33 and the lower slider 34 are each configured in a thin band shape, are parallel to each other, and are disposed on the apparatus main body 31 in a state of being movable in the longitudinal direction of the lower frame 23. The sliders 33 and 34 are slightly shorter in the longitudinal direction than the apparatus main body 31. Slider guide holes 33a and 34a are provided at appropriate positions of the upper slider 33 and the lower slider 34. The slider guide holes 33a and 34a are formed in a long hole shape in the longitudinal direction and have the same length. In the slider guide holes 33a, 34a, guide pins 35 provided in the apparatus main body 31 are inserted therethrough, respectively. The guide pins 35 are provided at the same pitch as the slider guide holes 33a, 34a, and function to define the movement range of each of the sliders 33, 34 by abutting against both end portions of the slider guide holes 33a, 34 a.

The upper slider 33 and the lower slider 34 are provided with a rack (interlocking member) 36 at the middle portion thereof and lock members 37 at both end portions thereof. The rack 36 is fixed to the surfaces of the sliders 33 and 34 facing each other, and teeth are provided at the portions facing each other at the same pitch. An interlocking gear (interlocking member) 38 is disposed between these racks 36. The interlocking gear 38 is disposed on the device main body 31 so as to be rotatable about a depth-direction shaft 38a, and meshes with the racks 36 of the sliders 33, 34. In the present embodiment, two identical interlocking gears 38 are provided in parallel with a space therebetween, and are engaged with the racks 36 of the sliders 33 and 34, respectively. The upper slider 33 and the lower slider 34 engaged with the interlocking gear 38 via the rack 36 are interlocked in a state of moving in opposite directions to each other. The lock members 37 are prism-shaped and fixed to the surfaces of the end portions of the sliders 33 and 34 that face each other. Each lock member 37 has a groove-shaped slider guide portion 37a, and is movable together with the sliders 33 and 34 with respect to the apparatus body 31 in a state where a guide rail 39 provided in the apparatus body 31 is fitted to the slider guide portion 37 a. The lock members 37 attached to the sliders 33 and 34, respectively, have the following dimensions: when the sliders 33 and 34 are accommodated in the apparatus main body 31, they can be accommodated in the apparatus main body 31 at the same time.

The input member 50 is connected to the upper slider 33, and the elevation drive member 60 is connected to the lower slider 34. The input member 50 has a connection hole 51, and is connected to the upper surface of the upper slider 33, wherein the connection pin 5 provided on the lower frame 23 can be inserted into the connection hole 51 when the apparatus main body 31 is disposed at the standard position. More specifically, the input member 50 is connected to the upper slider 33, and when the operating member 3 is placed in the lock position with the upper slider 33 moved to the rightmost side of the apparatus main body 31 as viewed from the indoor side and the lower slider 34 moved to the leftmost side, the connection pin 5 is inserted into the connection hole 51. As is clear from the figure, the coupling hole 51 of the input member 50 has a long hole shape in the depth direction, and when the coupling pin 5 is inserted, the relative movement in the depth direction is allowed, and the relative movement in the longitudinal direction of the upper slider 33 is restricted. That is, even in a state where the connection pin 5 is inserted into the connection hole 51 of the input member 50, the apparatus main body 31 can be rotated with respect to the lower frame 23 about the tilt shaft 41 of the hinge 40. On the other hand, when the operating member 3 moves in a state where the connecting pin 5 is inserted into the connecting hole 51 of the input member 50, the connecting pin 5 engages with the input member 50, the upper slider 33 is interlocked with the operating member 3, and the lower slider 34 is interlocked with the operating member 3 via the rack 36 and the interlocking gear 38.

Specifically, as shown in fig. 11-1, when the operating member 3 is disposed in the lock position, the following state is achieved: the lock member 37 provided on the upper slider 33 projects outward from the right side of the apparatus body 31, and the lock member 37 provided on the lower slider 34 projects outward from the left side of the apparatus body 31 (projecting position of the lock member 37). From this state to the state where the operating member 3 is disposed at the open position, as shown in fig. 11-2, the following states are obtained: the lock member 37 provided on the upper slider 33 and the lock member 37 provided on the lower slider 34 are housed in the device body 31 (the backward position of the lock member 37). Further, from this state to the time when the operating member 3 is disposed at the tilt position, as shown in fig. 11-3, the following state is achieved: the upper slider 33 is moved to the leftmost side, and the lock member 37 projects from the left side of the apparatus body 31 to the outside, while the lower slider 34 is moved to the rightmost side, and the lock member 37 projects from the right side of the apparatus body 31 to the outside (projecting position of the lock member 37). As is clear from the figure, in the present embodiment, the input members 50 having the same shape are provided at a plurality of portions of the upper slider 33. Each input member 50 is provided with an engagement portion 52. The engaging portion 52 protrudes from the upper edge portion to the outside of the room at the portion facing the outside of the room of the input member 50.

The elevation driving member 60 is connected to the upper member 61 and the lower member 62, thereby forming an inclined driving hole portion 60a therebetween. The inclined driving hole portion 60a is inclined to be bilaterally symmetrical with the both end portions low and the center portion high when viewed from the indoor side, and is connected to the lower surface of the lower slider 34. The elevation drive member 60 having the same shape is also provided at a plurality of positions of the lower slider 34.

Further, a watertight holding member 70 is disposed in the apparatus main body 31. The watertight holding member 70 is a block-shaped member, and is configured to have substantially the same length as the apparatus main body 31 in the longitudinal direction of the lower frame 23, and is provided with a watertight member 71 on the lower surface and the side surface facing the apparatus main body 31. The watertight member 71 is a member having a predetermined shape for securing a required water-tightness with the apparatus body 31 and with the lower frame 12, and is disposed on the entire lower surface and the entire side surface of the watertight holding member 70. A support shaft 72 is provided on a side surface of the watertight holding member 70 facing the device body 31. The support shafts 72 are cylindrical and extend in the depth direction, and the number thereof corresponds to the number of the elevation drive members 60. These support shafts 72 are inserted into the tilt driving hole portions 60a of the elevation driving member 60 via elevation guide portions 73 fixed to the apparatus main body 31. The elevation guide 73 has an elevation guide hole 73a extending in the vertical direction, and regulates the support shaft 72 inserted therein from moving left and right with respect to the apparatus main body 31.

On the other hand, as shown in fig. 8, the accessory device 30 includes: a hook member 80 attached to the lower frame 23; and a lock base member 90 attached to the left and right vertical frames 13, 14. The hook members 80 are fixed to the edge portion of the outer peripheral deep surface 23a of the lower frame 23 located outside the room, and the number thereof corresponds to the number of input members 50 of the apparatus main body 31. Each hook member 80 protrudes downward and is bent toward the indoor side. In a state where the apparatus main body 31 is disposed at the standard position, the hook members 80 can engage with the engagement portions 52 of the input member 50, and the apparatus main body 31 can be prevented from rotating about the tilting axis C2 with respect to the lower frame 23 at the time of engagement. In the present embodiment, as shown in fig. 10A to 10F, the hook member 80 is provided on the lower frame 23 such that: when the operation member 3 is disposed at the lock position and the open position with the connecting pin 5 inserted into the input member 50, the hook member 80 engages with the engagement portion 52 of the input member 50, and when the operation member 3 is disposed at the tilt position, the engagement state with the engagement portion 52 of the input member 50 is released.

The lock seat members 90 are fixed to portions of the left and right vertical frames 13 and 14 corresponding to both end portions of the apparatus main body 31, and as shown in fig. 8 and 9, engagement concave portions 91 are provided in portions thereof facing end surfaces of the lock member 37. The engagement recess 91 is a recess that is open to the outdoor side and closed to the indoor side, and can accommodate the lock member 37 protruding from the apparatus main body 31.

Hereinafter, the functions of the above-described accessory device 30 will be described, and the characteristic portions of the invention of the present application will be described in detail. For convenience, the left and right sides will be described as directions when viewed from the indoor side.

In the attachment device 30 configured as described above, when the handle 4 is disposed at the locked position with the door sash 20 closed, the operating member 3 is disposed at the locked position, and therefore, the upper slider 33 is moved to the right side and the lower slider 34 is moved to the left side with respect to the device main body 31. Therefore, the following states are obtained: the lock member 37 provided on the upper slider 33 engages with the lock base member 90 of the right vertical frame 13, and the lock member 37 provided on the lower slider 34 engages with the lock base member 90 of the left vertical frame 14. Thus, the device body 31 can be prevented from moving to the indoor side in a state where the door sash 20 is locked to the side frame body 10, and the theft prevention performance of the door can not be impaired.

Further, when the handle 4 is disposed at the locked position, the elevation drive member 60 connected to the lower slider 34 also moves to the left with respect to the device main body 31, and therefore the support shaft 72 of the watertight holding member 70 is guided downward by the inclined drive hole portion 60a, and the state in which the watertight holding member 70 moves downward with respect to the device main body 31 is maintained as shown in fig. 12. Thereby, the watertight member 71 provided on the lower surface of the watertight holding member 70 is brought into pressure contact with the inner peripheral deep surface of the lower frame 12.

As described above, in the state where the operating member 3 is disposed in the locked position, the engaging portion 52 of the input member 50 engages with the hook member 80, and the apparatus main body 31 is prevented from rotating with respect to the lower frame 23 and is maintained at the standard position, and therefore, the following states are achieved: the sealing members 15 and 26 provided on the outer peripheral fins 22b, 23b, 24b, and 25b of the lower frame 23 are pressed against the device body 31, and the fin-shaped sealing member 32 attached to the inner peripheral side deep surface 31c is in contact with the lower frame 23, and the fin-shaped sealing member 32 attached to the outer peripheral side deep surface 31d is in contact with the inner peripheral side deep surface of the lower bezel 12. Although not explicitly shown in the figure, the following states are achieved: at both ends of the apparatus body 31, the sealing members 15 and 26 provided at the inner peripheral fins 11b, 13b, and 14b of the vertical frames 13 and 14 are pressed against the front view surface facing the outside. As a result, between the lower frame 23 and the apparatus body 31 and between the apparatus body 31 and the lower frame 12, the required water tightness can be ensured between the respective members, and outdoor water such as rainwater does not penetrate into the indoor side.

When the handle 4 is operated from the above state to the inward opening position, the operating member 3 is disposed at the opening position, and therefore the lock member 37 is entirely housed inside the apparatus main body 31. As described above, when the handle 4 is disposed at the inward opening position, the door sash 20 can be opened with respect to the side frame 10 about the opening axis C1 because the upper support unit 2 is maintained in the locked state. At this time, the elevating drive member 60 connected to the lower slider 34 moves to the right side with respect to the apparatus main body 31, and the support shaft 72 of the watertight holding member 70 is disposed at the uppermost position, so that the watertight holding member 70 is maintained in a state of moving upward with respect to the apparatus main body 31 as shown in fig. 13A. As a result, the watertight member 71 provided on the lower surface of the watertight holding member 70 is spaced apart from the inner peripheral deep surface of the lower bezel 12, and the watertight member 71 does not hinder opening and closing of the door/window sash 20 around the opening axis C1.

When the handle 4 is returned to the locked position with the door sash 20 opened, the watertight holding member 70 moves downward with respect to the device body 31 as shown in fig. 13B, and thus the portion of the watertight member 71 closer to the opening axial center C1 comes into contact with the inner-peripheral deep surface of the lower frame 12. Therefore, the door sash 20 can be temporarily fixed in the opened state, and, for example, the door sash 20 can be prevented from being inadvertently closed.

On the other hand, when the handle 4 is operated to the retracted position from the state where the door sash 20 is closed, the operating member 3 is disposed at the tilted position, and therefore, the upper slider 33 moves to the left side and the lower slider 34 moves to the right side with respect to the apparatus main body 31. Therefore, the lock member 37 provided on the upper slider 33 engages with the lock seat member 90 of the left vertical frame 14, and the lock member 37 provided on the lower slider 34 engages with the lock seat member 90 of the right vertical frame 13, whereby the movement of the apparatus main body 31 to the indoor side is prevented. At this time, the elevating drive member 60 connected to the lower slider 34 moves to the right side with respect to the apparatus main body 31, and the support shaft 72 of the watertight holding member 70 is guided upward and then guided downward, and as shown in fig. 14, the state in which the watertight holding member 70 moves downward with respect to the apparatus main body 31 is maintained. Thereby, the watertight member 71 provided on the lower surface of the watertight holding member 70 is brought into pressure contact with the inner peripheral deep surface of the lower frame 12.

As described above, when the handle 4 is disposed at the retracted position, the upper support unit 2 is in the unlocked state, and the upper frame 22 can move parallel to the upper bezel 11. At this time, in the attachment device 30, since the engagement between the engagement portion 52 of the input member 50 and the hook member 80 is released, the device main body 31 can rotate about the tilting axis C2 with respect to the lower frame 23. Therefore, the door sash 20 can be rotated about the tilting axis C2 with respect to the device body 31, and the door sash 20 can be tilted inward with respect to the side frame 10.

In the above-described embodiment, the device body 31 is attached to the lower frame 23 so as to be rotatable with respect to the lower frame 23, and therefore, the door sash 20 can be tilted inward with respect to the bezel body 10. However, the device main body 31 does not necessarily have to be attached to the lower frame 23 so as to be rotatable with respect to the lower frame 23, and the device main body 31 may be directly fixed to the lower frame 23. In this case, the engaging portion 52, the hook member 80, and the lock member 37 of the input member 50 are not necessarily provided, and only a hinge may be used as a support means between the bezel body 10 and the door/window sash 20. The movement of the input member 50 is transmitted to the elevation driving member 60 via the upper and lower sliders 33 and 34 and the interlocking gear 38, but the elevation driving member 60 may be directly operated by the movement of the input member 50.

As described above, according to the present invention, there is provided a door window attachment device in which a door window sash is provided with an operating member that operates in response to an operation of a handle, and the door window attachment device is openable together with the door window sash about an opening axis in a vertical direction with respect to a side frame body when the operating member is moved from a lock position to an open position, the door window attachment device including: a device body mounted to a lower frame of the door and window sash; an input member that is disposed so as to be movable relative to the apparatus main body and is connected to the operating member; a watertight holding member which is disposed in the device body so as to be movable in a vertical direction of the door/window sash, and which holds the watertight member; and a connection mechanism that connects the input member and the watertight holding member and moves the watertight holding member relative to the apparatus main body by an operation of the input member, wherein the connection mechanism lowers the watertight holding member when the operation member is arranged at the lock position and raises the watertight holding member when the operation member is arranged at the open position.

According to the present invention, the watertight holding member is provided in the device body attached to the lower frame so as to be movable in the vertical direction, and when the operating member is disposed at the lock position, that is, when the door/window sash is closed, the watertight holding member can be lowered to bring the watertight holding member into pressure contact with the lower frame, and when the operating member is disposed at the open position, that is, when the door/window sash is opened and moved, the watertight holding member is raised.
