[0003] [Patent Document 1] JP 2015-86525 A Summary of the Invention [Problem to be solved by the invention]

[0004] By the way, it is possible to provide a sash window on an openable door body. A fitting in which a sash window is provided on an openable door body has a complex structure because of the large number of parts of the sash window. Furthermore, when a sash window is provided on a door body, the sash window tends to protrude to the outside, so there is room for improvement from the viewpoint of design.

[0005] Therefore, there is a demand for a fixture having an openable / closable door body with an openable / closable window provided in the door body that has a simple structure and improved design.

[0006] The present disclosure aims to provide a fitting having an openable / closable door body with an openable / closable window provided in the door body, which can be simply configured to improve design. [Means for solving the problem]

[0007] The present disclosure relates to a fixture comprising an openable and closable door body, the door body being provided with a window section that can be opened and closed by rotating about a rotation axis, the window section closing in conjunction with the opening action of the door body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] A fitting 1 of the first embodiment will be described. In this specification, the left-right direction in Fig. 1 is referred to as the left-right direction (horizontal direction). As shown in Figs. 1 to 3, the fitting 1 of the first embodiment comprises a frame body 21 arranged in an opening formed in a building (not shown), a door body 22 housed inside the frame body 21, a sleeve portion 23, a window opening / closing mechanism 3 (closing mechanism, speed adjustment mechanism), and a window holding / release mechanism 4 (holding mechanism, release mechanism).

[0010] The frame 21 has an upper frame 211, a lower frame 212, and a pair of vertical frames 213. The frame 21 is framed by the upper frame 211, the lower frame 212, and the pair of vertical frames 213 into a rectangular shape.

[0011] The upper frame 211 is disposed on the upper side of the frame body 21 and extends in the left-right direction (lateral direction). The lower frame 212 is disposed on the lower side of the frame body 21 and extends parallel to the upper frame 211 in the left-right direction (lateral direction).

[0012] The pair of vertical frames 213 connect both left and right ends of the upper frame 211 and both left and right ends of the lower frame 212, and extend in the up-down direction (vertical direction).

[0013] The sleeve portion 23 is disposed so as to cover approximately half of one side in the left-right direction inside the frame body 21. The sleeve portion 23 has a upright 231 that is disposed in the middle in the left-right direction inside the frame body 21 and extends in the vertical direction, and a sleeve panel 232 that is fixedly disposed on one side of the upright 231 in the left-right direction.

[0014] The sleeve panel 232 is a FIX panel fixed to the inside part of one side of the frame body 21 in the left-right direction and the inside part of the upright 231. Inside the frame body 21, the other side in the left-right direction where the sleeve panel 23 is not located becomes an opening 214 that is opened and closed by the door body 22.

[0015] The door body 22 can open and close the opening 214 of the frame body 21 by moving left and right (lateral direction). The door body 22 is disposed on the outdoor side of the sleeve portion 23 and is disposed on the outdoor side of the sleeve portion 23 so as to be movable left and right (lateral direction).

[0016] The door body 22 is located in the closed position when it is located in the opening 214 on the other left-right side of the frame body 21 where the sleeve portion 23 is not located, and is located in the open position when it is moved to a position overlapping with the sleeve portion 23 on the outdoor side of the sleeve portion 23 on one left-right side of the frame body 21 where the sleeve portion 23 is located. In this embodiment, the door body 22 constitutes a single-sliding door that can move left-right inside the frame body 21.

[0017] The door body 22 has a door body main body 221, an indoor handle 222, an outdoor handle (not shown), and an air intake window 223 (window portion). The door body 221 is formed in a rectangular plate shape. The door body 221 is formed with a rectangular opening 221a in which the air intake window 223 is arranged.

[0018] The indoor side handle 222 is disposed on the door tip side of the door body 221, on the indoor side surface of the door body 221. The outdoor side handle (not shown) is disposed on the door tip side of the door body 221, on the outdoor side surface of the door body 221. The user can move the door body 22 to the open position or the closed position by placing their hand on the indoor side handle 222 or the outdoor side handle and moving the door body 22 left and right.

[0019] The ventilating window 223 is disposed in the opening 221a of the door body 22. The ventilating window 223 is formed in the shape of a rectangular plate. The ventilating window 223 is a vertical sliding type window that can be opened and closed by rotating about a rotation axis J1 that is formed on the hanging side and extends in the up-down direction (vertical direction), and the rotation axis J1 can slide in the horizontal direction. The details will be described later, but the ventilating window 223 closes in conjunction with the opening operation of the door body 22.

[0020] In this embodiment, the ventilation window 223 is configured as an inward-opening window that opens to the indoor side. By opening the ventilation window 223, ventilation and ventilation to the indoor side can be performed, and ventilation can be made possible even when the door body 22 is in the closed position.

[0021] A handle 223a is provided on the indoor surface of the door tip side of the ventilating window 223. The handle 223a has a recess 223b recessed from the surface of the ventilating window 223 and a handle plate 223c that covers a part of the recess 223b. The user can open the ventilating window 223 from the closed position by inserting his / her hand into the recess 223b of the handle 223a and pulling the ventilating window 223 indoors while hooking the hand on the handle plate 223c.

[0022] In this embodiment, the ventilating window 223 is supported so as to be openable and closable by a friction stay 224. The friction stay 224 is provided at the lower end of the ventilating window 223. As shown in FIG. 4 , the friction stay 224 connects the lower surface of the ventilating window 223 to an opening gutter 221c formed on an opening upper surface 221b extending laterally at the lower part of the opening 221a of the door body 22.

[0023] 4, an other-end pin 223e is provided on the lower surface of the air intake window 223 at the other end of the lower surface of the door body 22 in the longitudinal direction (the end on the right side in the upper view of FIG. 4) and an intermediate pin 223d is provided at a middle portion in the longitudinal direction of the lower surface of the door body 22. As a result, the door body 22 can rotate about the rotation axis J1 of the other-end pin 223e, and moves left and right as the other-end pin 223e moves left and right along the opening groove 221c on the opening upper surface 221b formed at the bottom of the opening 221a of the door body 22.

[0024] The friction stay 224 is formed in a long plate shape having a groove 224a extending in the longitudinal direction, as shown in Fig. 4. One end in the longitudinal direction of the friction stay 224 is rotatably connected to a one-end pin 221e provided at one end in the left-right direction (the left end in Fig. 4) of the opening groove 221c on the opening upper surface 221b at the bottom of the opening 221a of the door body 22, and the other end in the longitudinal direction is rotatably connected to an intermediate pin 223d.

[0025] By providing the friction stay 224 described above, when the air intake window 223 is in a closed state, for example, by a user putting his / her hand on the handle portion 223a and pulling the air intake window 223 towards himself / herself, the air intake window 223 moves along the opening groove 221c while rotating about the rotation axis J1 provided on the other side in the left-right direction as shown in the upper and lower views of Fig. 4 while being supported by the friction stay 224. In this way, the air intake window 223 constitutes a vertical sliding type window that can be opened and closed by rotating about the rotation axis J1 formed on the hanging side and extending in the up-down direction (vertical direction), and the rotation axis J1 can slide horizontally.

[0026] The window opening / closing mechanism 3 (closing mechanism, speed adjustment mechanism) functions as a closing mechanism that closes the ventilating window 223 with a closing force that moves the ventilating window 223 from the open position side toward the closed position side, and also functions as a speed adjustment mechanism that adjusts the opening / closing speed at which the ventilating window 223 moves from the open position to the closed position. In this embodiment, the window opening / closing mechanism 3 is equipped with both a closing mechanism that closes the ventilating window 223 with a closing force, and a speed adjustment mechanism that adjusts the opening / closing speed of the ventilating window 223.

[0027] In this embodiment, as shown in Fig. 1 to Fig. 3, the window opening and closing mechanism 3 has a gas spring 31 and a wire 32. The gas spring 31 is disposed on the side of the hanging point of the ventilating window 223 in the opening 221a of the door body 22. The gas spring 31 is disposed in a position where it is not exposed to the outside. The wire 32 connects the end of the ventilating window 223 on the door tip side to the gas spring 31.

[0028] An end of a wire 32 is connected to the gas spring 31. The gas spring 31 accumulates the reaction force of the gas sealed in the cylinder as a spring force, and generates a closing force that moves the air intake window 223 connected to the wire 32 from the open position side to the closed position side by the spring force. When closing the air intake window 223 connected to the wire 32, the gas spring 31 adjusts and damps the opening and closing speed of the air intake window 223 to close the air intake window 223.

[0029] The window hold release mechanism 4 (holding mechanism, release mechanism) functions as a holding mechanism that holds the ventilating window 223 in the open position and the closed position, and also functions as a release mechanism that releases the hold of the ventilating window 223 held in the open position. In this embodiment, the window hold release mechanism 4 includes both a holding mechanism that holds the ventilating window 223 in the open position, and a release mechanism that releases the hold of the ventilating window 223 held in the closed position.

[0030] As shown in Figures 2 and 3, the window retention release mechanism 4 has a plunger member 41 (pressure retention member) arranged inside the upper part of the door body 22, a closed position engagement recess 42 formed in the longitudinal middle part of the upper surface of the air intake window 223, an open position engagement recess 43 formed on the hanging side of the upper surface of the air intake window 223, and a plunger restriction release portion 44 provided on the upper frame 211.

[0031] The plunger member 41 holds the ventilating window 223 in the door body 22. The plunger member 41 is provided inside the door body 22, above the ventilating window 223. The plunger member 41 is disposed penetrating in the vertical direction through an upper portion of the opening 221a in the door body 22. The plunger member 41 is disposed in a position that is not exposed to the outside.

[0032] As shown in Figures 5 and 6, the plunger member 41 has a plunger body 411 extending in the vertical direction, a plunger side spring 412 that urges the plunger body 411 upward, a position regulating portion 413 that regulates the upward movement of the plunger member 41, an engaging ball portion 414 (engaging member) arranged at the lower end of the plunger body 411, and a ball side spring 415 that urges the engaging ball portion 414 downward.

[0033] 2 and 5, the closed position engagement recess 42 is formed in a downwardly recessed shape in the longitudinal middle portion of the upper surface 223f of the ventilation window 223. When the ventilation window 223 is located in the closed position, the engagement ball portion 414 of the plunger member 41 engages with the closed position engagement recess 42.

[0034] When the air intake window 223 is closed from an open state, the engaging ball portion 414 is biased downward by the ball side spring 415 and moves while pressing the upper surface 223f of the air intake window 223. Then, when the engaging ball portion 414 moves to a position where the closed position engaging recess 42 is formed, it engages with the closed position engaging recess 42. The engaging ball portion 414 protrudes from the door body 22 toward the air intake window 223 and engages with the air intake window 223, thereby holding the air intake window 223 to the door body 22. As a result, the air intake window 223 is held in the closed position.

[0035] 3 and 6, the open position engagement recess 43 is formed in a downwardly recessed shape at the end of the upper surface 223f of the ventilation window 223 on the hanging side in the longitudinal direction. When the ventilation window 223 is located in the open position, the engagement ball portion 414 of the plunger member 41 engages with the open position engagement recess 43.

[0036] When the air intake window 223 is opened from a closed state, the engaging ball portion 414 moves while being biased downward by the ball side spring 415 and pressing the upper surface 223f of the air intake window 223. When the engaging ball portion 414 moves to a position where the open position engaging recess 43 is formed, it engages with the open position engaging recess 43. This causes the air intake window 223 to be held in the open position.

[0037] The plunger restriction release part 44 releases the hold of the ventilation window 223 by the window hold release mechanism 4 in conjunction with the opening operation of the door body 22. The plunger restriction release part 44 restricts or releases the position of the upper end part of the plunger member 41 depending on the left-right position of the door body 22.

[0038] The plunger restriction release portion 44 is formed in an uneven shape along the left-right direction of the upper frame 211. The plunger restriction release portion 44 has a restriction flat portion 441 formed on the door end side in the left-right direction of the door body 22, and a release recess 442 formed on the sleeve portion 23 side in the left-right direction of the door body 22 and recessed upward from the restriction flat portion 441.

[0039] The restricting flat portion 441 is formed by the lower surface of the upper frame 211 in approximately half of the area on the left-right door end side of the opening 214 opened and closed by the door body 22, and extends horizontally in the left-right direction. The upper end of the plunger member 41 abuts against the restricting flat portion 441. The plunger member 41 is pressed downward by the restricting flat portion 441 while being biased upward. The engaging ball portion 414 arranged on the tip side of the plunger member 41 is pressed downward. As a result, the engaging ball portion 414 engages with the closed position engaging recess 42 when the air intake window 223 is in the closed position, and engages with the open position engaging recess 43 when the air intake window 223 is in the open position.

[0040] The release recess 442 has a release inclined surface portion 443 and a retraction flat surface portion 444. The release inclined surface portion 443 is formed by the lower surface of the upper frame 211 at approximately the center in the left-right direction of the opening 214 that is opened and closed by the door body 22. The release inclined surface portion 443 is formed continuously with the restricting flat surface portion 441 at the end of the restricting flat surface portion 441 on the sleeve portion 23 side in the left-right direction. The release inclined surface portion 443 is formed by an inclined surface facing downward, and inclines from the bottom to the top as it approaches the sleeve portion 23 side.

[0041] The retraction flat surface 444 is connected to the end of the release inclined surface 443 on the sleeve portion 23 side in the left-right direction, and extends horizontally toward the sleeve portion 23. When the door body 22 moves to the sleeve portion 23 side in the left-right direction, the upper end of the plunger member 41, which is no longer under downward pressure from the release inclined surface 443, is retracted into the space below the retraction flat surface 444.

[0042] The upper end of the plunger member 41 moves while being in contact with the inclined surface of the release inclined surface portion 443 as the door body 22 moves in the left-right direction. In conjunction with the movement of the door body 22 from the closed position to the open position, the plunger member 41 gradually changes from a state in which it is pressed downward by the release inclined surface portion 443 to a state in which it is not pressed downward by the release inclined surface portion 443 according to the inclination angle of the release inclined surface portion 443.

[0043] As a result, the engagement ball portion 414 located on the tip side of the plunger member 41 is no longer subjected to the downward pressing force from the plunger member 41 pressed against the release inclined surface portion 443 at a predetermined position in the left-right direction on the release inclined surface portion 443, and is moved upward, thereby releasing the engagement with the closed position engagement recess 42 or the open position engagement recess 43.

[0044] In this way, the plunger restriction release portion 44 moves the engagement ball portion 414 from a position protruding from the door body 22 to a position where it does not protrude in conjunction with the opening action of the door body 22, thereby releasing the engagement of the engagement ball portion 414 with the ventilation window 223.

[0045] Here, when the air intake window 223 is in the open position, the engagement with the open position engagement recess 43 is released, and the air intake window 223 is released from the state in which it was held in the open position. By releasing the state in which the air intake window 223 is held in the open position, the air intake window 223 can be closed by a closing force that moves the air intake window 223 in the window opening / closing mechanism 3 from the open position side toward the closed position side.

[0046] Next, in the first embodiment, a description will be given of the operation of the fitting 1 when the ventilating window 223 closes in conjunction with the opening operation of the door body 22. First, with the door body 22 positioned in the closed position, a user hooks their hand on the handle portion 223a of the ventilating window 223 and pulls the ventilating window 223 toward the inside of the room, thereby moving the ventilating window 223 from the closed position to the open position.

[0047] When the door body 22 is in the closed position, the plunger member 41 of the window holding release mechanism 4 is biased upward, and its upper end is pressed downward by the restricting flat surface portion 441. The engaging ball portion 414 arranged on the tip side of the plunger member 41 engages with the closed position engaging recess 42 when the ventilation window 223 is in the closed position as shown in FIG. 2, and thus the ventilation window 223 is held by the window holding release mechanism 4 as shown in FIG. 5 while being positioned in the closed position as shown in FIG.

[0048] Also, even when the air intake window 223 is moved from the closed position to the open position, the plunger member 41 of the window holding release mechanism 4 is biased upward and has its upper end pressed downward by the restricting flat surface portion 441. The engaging ball portion 414 arranged on the tip side of the plunger member 41 engages with the open position engaging recess 43 at the open position of the air intake window 223 by moving the air intake window 223 from the closed position to the open position. As a result, the air intake window 223 is held by the window holding release mechanism 4 as shown in FIG. 6 in a state where it is positioned in the open position as shown in FIG. 3.

[0049] Next, with the ventilation window 223 open, the user moves the door body 22 from the closed position to the open position, so that the door body 22 moves in the left-right direction toward the sleeve portion 23. In this case, the plunger member 41 disposed inside the door body 22 moves in the left-right direction toward the sleeve portion 23 together with the opening and closing movement of the door body 22.

[0050] 6 to the position shown in Fig. 7 in the left-right direction, and reaches a position where the release inclined surface portion 443 of the plunger restriction release portion 44 of the window holding release mechanism 4 provided on the upper frame 211 is formed. In conjunction with the movement of the door body 22 from the closed position to the open position, the plunger member 41 gradually goes from a state in which it is pressed downward by the release inclined surface portion 443 to a state in which it is not pressed downward by the release inclined surface portion 443 in accordance with the inclination angle of the release inclined surface portion 443.

[0051] As a result, the engagement ball portion 414 located on the tip side of the plunger member 41 is no longer subjected to the downward pressing force from the plunger member 41 pressed against the release inclined surface portion 443 at a predetermined position in the left-right direction on the release inclined surface portion 443, and is moved upward, thereby releasing its engagement with the open position engagement recess 43.

[0052] When the engaging ball portion 414 is moved upward and disengaged from the open position engaging recess 43, the closing force of the gas spring 31 of the window opening / closing mechanism 3 causes the door end side of the ventilating window 223 to be pulled by the wire 32. As a result, the ventilating window 223 is moved from the open position to the closed position.

[0053] In this way, when the ventilating window 223 is in the open position, even if the door body 22 is moved from the closed position toward the open position, the ventilating window 223 is moved from the open position to the closed position before reaching the mullion 231 of the sleeve 23. This allows the ventilating window 223 to close in conjunction with the opening action of the door body 22. This prevents the ventilating window 223 from getting in the way when the door body 22 is opened, and also prevents the ventilating window 223 from colliding with the sleeve 23 (the mullion 231).

[0054] According to the first embodiment, the following effects are achieved. The fitting 1 of this embodiment is equipped with an openable / closable door body 22, and the door body 22 is provided with an openable / closable ventilation window 223 that rotates around the rotation axis J1, and the ventilation window 223 closes in conjunction with the opening operation of the door body 22. This allows the fitting 1 in which the openable / closable ventilation window 223 is provided in the door body 22 to have improved design with a simple configuration. In addition, since the ventilation window 223 closes in conjunction with the opening operation of the door body 22, the ventilation window 223 can be prevented from getting in the way when the door body 22 is opened. In addition, in the case where a sleeve portion 23 is provided in the direction in which the door body 22 is opened, the ventilation window 223 can be prevented from colliding with the sleeve portion 23 when the door body 22 is opened.

[0055] In this embodiment, the window opening / closing mechanism 3 closes the ventilating window 223 by a closing force that moves the ventilating window 223 from the open position side toward the closed position side, and the window holding release mechanism 4 holds the ventilating window 223 in the open position and releases the holding of the ventilating window 223 in conjunction with the opening operation of the door body 22. As a result, when the window holding release mechanism 4 holds the ventilating window 223 in the open position and the holding of the ventilating window 223 is released by the window holding release mechanism 4 in conjunction with the opening operation of the door body 22, the ventilating window 223 can be closed by the closing force of the ventilating window 223 in the window opening / closing mechanism 3. Therefore, the ventilating window 223 can be closed in conjunction with the opening operation of the door body 22 with a simple configuration. Therefore, when the door body 22 is opened, the ventilating window 223 can be prevented from getting in the way with a simple configuration.

[0056] In addition, in this embodiment, a window opening and closing mechanism 3 is provided that adjusts the opening and closing speed at which the ventilating window 223 moves from the open position to the closed position. This allows the ventilating window 223 to be closed while attenuating the sound.

[0057] Furthermore, in this embodiment, the window hold release mechanism 4 has a plunger member 41 that holds the ventilation window 223 to the door body 22, and the plunger member 41 is provided to the door body 22. By providing the plunger member 41 inside the door body 22, the window hold release mechanism 4 can be provided in a portion of the door body 22 that cannot be seen from the outside, thereby improving the design.

[0058] In this embodiment, the window retention release mechanism 4 has an engagement ball portion 414 that protrudes from the door body 22 toward the ventilation window 223 and engages with the ventilation window 223 to retain the ventilation window 223 on the door body 22, and the window retention release mechanism 4 releases the engagement of the engagement ball portion 414 with the ventilation window 223 by moving the engagement ball portion 414 from a position protruding from the door body 22 to a position where it does not protrude in conjunction with the opening operation of the door body 22. As a result, the ventilation window 223 can be held in the open position by engaging with the engagement ball portion 414, and the engagement of the engagement ball portion 414 with the ventilation window 223 can be released. Therefore, with a simple configuration, the ventilation window 223 can be held in the open position and the retention of the ventilation window 223 can be released.

[0059] Next, the fitting 1A of the second embodiment will be described. The description of the first embodiment can be applied to the points not described in the second embodiment. In the second embodiment, the same components as those in the first embodiment are given the same reference numerals as those in the first embodiment, and the description thereof will be omitted.

[0060] As shown in Figs. 8 to 10, a fitting 1A of the second embodiment includes a window hold releasing mechanism 4A instead of the window hold releasing mechanism 4 of the first embodiment.

[0061] The window hold release mechanism 4A (holding mechanism, release mechanism) functions as a holding mechanism that holds the ventilating window 223 in the open position and the closed position, and also functions as a release mechanism that releases the hold of the ventilating window 223 held in the open position. In this embodiment, the window hold release mechanism 4A includes both a holding mechanism that holds the ventilating window 223 in the open position, and a release mechanism that releases the hold of the ventilating window 223 held in the closed position.

[0062] As shown in Figures 11 and 12, the window hold release mechanism 4A has a plunger member 45 arranged inside the upper part of the ventilation window 223, a closed position engagement recess 46, an open position engagement recess 47, and a plunger restriction release portion 48.

[0063] The plunger member 45 holds the ventilating window 223 to the door body 22. The plunger member 45 is provided inside the ventilating window 223 on the hanging side of the upper part of the ventilating window 223, as shown in Figs.

[0064] The plunger member 45 has an engagement ball portion 451 (engagement member) disposed at the upper end, and a ball-side spring 452 that biases the engagement ball portion 451 upward.

[0065] 9 and 11, the closed position engagement recess 46 is formed in a concave shape recessed upward on the hanging side of the ventilation window 223 on the lower surface 221d formed in the upper part of the opening 221a of the door body 22. When the ventilation window 223 is located in the closed position, the engagement ball portion 451 of the plunger member 45 engages with the closed position engagement recess 46.

[0066] When the ventilating window 223 is closed from an open state, the engaging ball portion 451 is biased upward by the ball side spring 452 and moves while pressing the lower surface 221d formed at the upper part of the opening 221a of the door body 22. Then, when the engaging ball portion 451 moves to a position where the closed position engaging recess 46 is formed, it engages with the closed position engaging recess 46. The engaging ball portion 451 protrudes from the ventilating window 223 toward the door body 22 and engages with the door body 22, thereby holding the ventilating window 223 to the door body 22. As a result, the ventilating window 223 is held in the closed position.

[0067] 10 and 12, the open position engagement recess 47 is formed in an upwardly recessed shape at a left-right intermediate position of the lower surface 221d formed at the upper part of the opening 221a of the door body 22. The engagement ball portion 451 of the plunger member 45 engages with the open position engagement recess 47 when the air intake window 223 is located in the closed position.

[0068] When the ventilation window 223 is opened from a closed state, the engaging ball portion 451 is biased upward by the ball side spring 452 and moves while pressing the lower surface 221d formed on the upper part of the opening 221a of the door body 22. Then, when the engaging ball portion 451 moves to a position where the open position engaging recess 47 is formed, it engages with the open position engaging recess 47. As a result, the ventilation window 223 is held in the open position.

[0069] The plunger deregulation part 48 releases the hold of the ventilation window 223 by the window hold release mechanism 4A in conjunction with the opening operation of the door body 22. The plunger deregulation part 48 has a control cable 481 connected to the upper end of the open position engagement recess 47 and arranged extending in the vertical direction inside the upper part of the door body 22, and a control cable deregulation part 482. The plunger deregulation part 48 restricts or releases the position of the upper end of the cable member 481b of the control cable 481 depending on the position of the door body 22 in the left-right direction.

[0070] The control cable 481 has an outer tube 481a and a cable member 481b disposed inside the outer tube 481a. The outer tube 481a is formed in a cylindrical shape and extends in the vertical direction from the upper end of the open position engagement recess 47 to the upper surface 221f of the door body 22. The cable member 481b is disposed so that an upper end portion thereof can protrude from the upper surface 221f of the door body 22, and a lower end portion thereof is disposed so as to protrude inside the open position engagement recess 47.

[0071] When the air intake window 223 is in the open position, as shown in Fig. 12 and Fig. 13, the lower end of the cable member 481b abuts against the engaging ball portion 451 of the plunger member 45 inside the open position engaging recess 47. When the upper end of the cable member 481b is not pressed, as shown in Fig. 12, the lower end of the cable member 481b abuts against the engaging ball portion 451 without pressing the engaging ball portion 451. When the upper end of the cable member 481b is pressed, as shown in Fig. 13, the lower end of the cable member 481b abuts against the engaging ball portion 451 while pressing the engaging ball portion 451 downward.

[0072] The control cable restriction release portion 482 is formed in an uneven shape along the left-right direction of the upper frame 211. The control cable restriction release portion 482 has a release flat portion 482a formed on the door end side in the left-right direction of the door body 22, and a restriction protrusion 482b formed on the sleeve portion 23 side in the left-right direction of the door body 22 and protruding downward from the release flat portion 482a.

[0073] The release flat surface 482a is formed by the lower surface of the upper frame 211, and is formed above the upper end of the cable member 481b in approximately half of the area on the left-right door end side of the opening 214 that is opened and closed by the door body 22. A space is formed between the release flat surface 482a and the upper surface 221f of the door body 22, into which the upper end of the cable member 481b can be retracted.

[0074] The restricting protrusion 482b has a restricting inclined surface portion 482c and a restricting flat surface portion 482d. The restricting inclined surface portion 482c is formed by the lower surface of the upper frame 211 at approximately the center in the left-right direction of the opening 214 that is opened and closed by the door body 22. The restricting inclined surface portion 482c is formed continuously with the releasing flat surface portion 482a at the end of the releasing flat surface portion 482a on the sleeve portion 23 side in the left-right direction. The restricting inclined surface portion 482c is formed by an inclined surface facing downward, and inclines from the top to the bottom as it approaches the sleeve portion 23 side.

[0075] The upper end of the cable member 481b moves in contact with the inclined surface of the restricting inclined surface portion 482c as the door body 22 moves in the left-right direction. As the door body 22 moves from the closed position to the open position, the upper end of the cable member 481b gradually changes from a state in which it is not pressed downward by the restricting inclined surface portion 482c to a state in which it is pressed downward by the restricting inclined surface portion 482c according to the inclination angle of the restricting inclined surface portion 482c.

[0076] The restricting flat surface portion 482d is connected to the end portion of the restricting inclined surface portion 482c on the left-right side of the sleeve portion 23, and extends horizontally toward the sleeve portion 23. When the door body 22 moves toward the sleeve portion 23 in the left-right direction, the restricting flat surface portion 482d maintains a state in which the upper end portion of the cable member 481b is pressed by the restricting inclined surface portion 482c.

[0077] 12, when the upper end of the cable member 481b is not pressed against the restricting inclined surface portion 482c, the lower end of the cable member 481b does not press the engaging ball portion 451 arranged on the tip side of the plunger member 45, so that the engaging ball portion 451 is biased upward. Therefore, the engaging ball portion 451 engages with the open position engaging recess 47 when the air intake window 223 is in the open position.

[0078] 13, when the upper end of the cable member 481b is pressed against the restricting inclined surface portion 482c or the restricting flat surface portion 482d, the lower end of the cable member 481b presses the engaging ball portion 451. In this case, since the lower end of the cable member 481b presses the engaging ball portion 451, the engaging ball portion 451 is pressed downward to a position where it does not engage with the open position engaging recess 47.

[0079] As a result, the engagement ball portion 451 arranged on the tip side of the plunger member 45 is moved downward by the lower end of the cable member 481b at a predetermined left-right position on the regulating inclined surface portion 482c or the regulating flat surface portion 482d, as the upper end of the cable member 481b is pressed against the regulating inclined surface portion 482c, and the engagement with the open position engagement recess 47 is released.

[0080] In this way, the plunger restriction release portion 48 releases the engagement of the engagement ball portion 451 with the door body 22 by moving the engagement ball portion 451 from a position protruding from the ventilation window 223 to a position where it does not protrude in conjunction with the opening action of the door body 22.

[0081] Here, when the air intake window 223 is in the open position, the engagement with the open position engagement recess 47 is released, and the air intake window 223 is released from the state in which it was held in the open position. By releasing the state in which the air intake window 223 is held in the open position, the air intake window 223 can be closed by a closing force that moves the air intake window 223 in the window opening / closing mechanism 3 from the open position side toward the closed position side.

[0082] Next, in the second embodiment, a description will be given of the operation of the fitting 1A when the ventilating window 223 closes in conjunction with the opening operation of the door body 22. First, with the door body 22 positioned in the closed position, a user hooks their hand on the handle portion 223a of the ventilating window 223 and pulls the ventilating window 223 toward the inside of the room, thereby moving the ventilating window 223 from the closed position to the open position.

[0083] When the door body 22 is in the closed position, the engaging ball portion 451 disposed on the tip side of the plunger member 45 engages with the closed position engaging recess 46 in the closed position of the ventilation window 223. As a result, the ventilation window 223 is held in the closed position as shown in Fig. 9 by the window holding release mechanism 4A as shown in Fig. 11.

[0084] Also, even when the air intake window 223 is moved from the closed position to the open position, the engaging ball portion 451 disposed on the tip side of the plunger member 45 engages with the open position engaging recess 47 at the open position of the air intake window 223. As a result, the air intake window 223 is held by the window holding release mechanism 4A as shown in FIG. 12 in a state in which it is positioned at the open position as shown in FIG. 10.

[0085] Next, with the ventilation window 223 open, the user moves the door body 22 from the closed position to the open position, so that the door body 22 moves in the left-right direction toward the sleeve section 23. In this case, the plunger member 45 arranged inside the ventilation window 223 and the control cable 481 arranged inside the door body 22 move in the left-right direction toward the sleeve section 23 together with the opening and closing movement of the door body 22.

[0086] Then, the control cable 481 is moved in the left-right direction from the position shown in Figure 12 to the position shown in Figure 13, and the upper end of the cable member 481b is pressed against the restricting inclined surface portion 482c or the restricting flat surface portion 482d at a predetermined position in the left-right direction of the restricting inclined surface portion 482c or the restricting flat surface portion 482d of the control cable restriction release portion 482 of the window holding release mechanism 4A provided on the upper frame 211.

[0087] As a result, the engaging ball portion 451 arranged on the tip side of the plunger member 45 is moved downward by the lower end portion of the cable member 481b, and the engagement with the open position engaging recess 47 is released.

[0088] When the engaging ball portion 451 is moved downward and disengaged from the open position engaging recess 47, the closing force of the gas spring 31 of the window opening / closing mechanism 3 causes the door end side of the ventilating window 223 to be pulled by the wire 32. As a result, the ventilating window 223 is moved from the open position to the closed position.

[0089] In this way, when the ventilating window 223 is in the open position, even if the door body 22 is moved in the closing direction, the ventilating window 223 is moved from the open position to the closed position before reaching the mullion 231 of the sleeve 23. This allows the ventilating window 223 to close in conjunction with the closing action of the door body 22. Therefore, when the door body 22 is opened, the ventilating window 223 can be prevented from getting in the way, and the ventilating window 223 can be prevented from colliding with the sleeve 23 (the mullion 231).

[0090] According to the second embodiment, in addition to the same effects as those of the first embodiment, the following effects are achieved. In the fitting 1A of this embodiment, the plunger member 45 of the window hold release mechanism 4A is provided inside the ventilation window 223. Therefore, compared to the first embodiment in which the plunger member 41 is provided inside the door body 22, the insulation material can be provided without providing a space for the plunger member 45 inside the door body 22, so that the deterioration of the insulation performance of the door body 22 can be minimized.

[0091] Next, the fitting 1B of the third embodiment will be described. The explanation of the second embodiment can be applied to the points not explained in the third embodiment. In the third embodiment, the same components as those in the second embodiment are given the same reference numerals as those in the second embodiment, and the explanation thereof will be omitted.

[0092] As shown in Figs. 14 to 16, in a fitting 1B of the third embodiment, a door body 22 is provided with a handle latch mechanism part 24, and a window hold release mechanism 4B is provided instead of the window hold release mechanism 4A of the second embodiment.

[0093] The door body 22 is opened and closed by operating the indoor handle 222 or the outdoor handle (not shown). The door body 22 has a handle latch mechanism 24. A latch 241 of the handle latch mechanism 24 is released in conjunction with the operation of the indoor handle 222 and the outdoor handle to open the door body 22.

[0094] The window hold release mechanism 4B (holding mechanism, release mechanism) functions as a holding mechanism that holds the ventilating window 223 in the open position and the closed position, and also functions as a release mechanism that releases the hold of the ventilating window 223 held in the open position. In this embodiment, the window hold release mechanism 4B is equipped with both a holding mechanism that holds the ventilating window 223 in the open position, and a release mechanism that releases the hold of the ventilating window 223 held in the closed position. The window hold release mechanism 4B releases the hold of the ventilating window 223 by the window hold release mechanism 4B when the latch 241 is released in conjunction with the opening action of the door body 22 by the operation of opening the door body 22 by the indoor side handle 222 or the outdoor side handle.

[0095] As shown in Figures 17 and 18, the window retention release mechanism 4B has a plunger member 61 (pressure retaining member) arranged inside the upper part of the air intake window 223, a closed position engagement recess 62, an open position engagement recess 63, and a pressure cup member restriction release portion 64.

[0096] The plunger member 61 holds the ventilating window 223 to the door body 22. The plunger member 61 is provided inside the ventilating window 223 on the hanging side of the upper part of the ventilating window 223.

[0097] As shown in FIGS. 17 and 18, the plunger member 61 has an engagement ball portion 611 (engagement member) disposed at the upper end, and a ball side spring 612 that biases the engagement ball portion 611 upward.

[0098] 17 and 18, the closed position engagement recess 62 is formed in a concave shape recessed upward on the hanging side of the ventilation window 223 on the lower surface 221d formed in the upper part of the opening 221a of the door body 22. The engagement ball portion 611 of the plunger member 61 engages with the closed position engagement recess 62 when the ventilation window 223 is located in the closed position.

[0099] When the air intake window 223 is closed from an open state, the engaging ball portion 611 is biased upward by the ball side spring 612 and moves while pressing the lower surface 221d formed at the upper part of the opening 221a of the door body 22. Then, when the engaging ball portion 611 moves to a position where the closed position engaging recess 62 is formed, it engages with the closed position engaging recess 62. The engaging ball portion 611 protrudes from the air intake window 223 toward the door body 22 and engages with the door body 22, thereby holding the air intake window 223 to the door body 22. As a result, the air intake window 223 is held in the closed position.

[0100] 17 and 18, the open position engagement recess 63 is formed in an upwardly recessed shape at a left-right intermediate position of the lower surface 221d formed at the upper part of the opening 221a of the door body 22. When the air intake window 223 is in the open position, the engagement ball portion 611 of the plunger member 61 engages with the open position engagement recess 63.

[0101] When the ventilation window 223 is opened from a closed state, the engaging ball portion 611 is biased upward by the ball side spring 612 and moves while pressing the lower surface 221d formed on the upper part of the opening 221a of the door body 22. Then, when the engaging ball portion 611 moves to a position where the open position engaging recess 63 is formed, it engages with the open position engaging recess 63. As a result, the ventilation window 223 is held in the open position.

[0102] The pressure cup member deregulation portion 64 has a control cable 641 and a control cable deregulation portion 642. The control cable deregulation portion 642 is configured by a part of the handle latch mechanism portion 24.

[0103] The control cable 641 has an outer tube 641a and a cable member 641b disposed inside the outer tube 641a. The outer tube 641a is formed in a cylindrical shape and extends from the upper end of the open position engagement recess 63 to the handle latch mechanism 24. One end of the cable member 641b is disposed protruding inside the open position engagement recess 63, and the other end is connected to the handle latch mechanism 24.

[0104] As shown in FIG. 18, when the cable member 641b is not pushed toward the engagement ball portion 611 by the control cable restriction release portion 642 and is not pressing against the engagement ball portion 611, one end of the cable member 641b abuts against the engagement ball portion 611 without pressing against the engagement ball portion 611.

[0105] When the cable member 641b is not pushed out by the control cable restriction release portion 642, the engaging ball portion 611 arranged on the tip side of the plunger member 61 is in a state of being biased upward because one end of the cable member 641b does not press the engaging ball portion 611. Therefore, the engaging ball portion 611 engages with the open position engaging recess 63 when the air intake window 223 is in the open position.

[0106] 19, when the cable member 641b is pushed toward the engaging ball portion 611 by the control cable restriction release portion 642, one end of the cable member 641b presses the engaging ball portion 611. In this case, since one end of the cable member 641b presses the engaging ball portion 611, the engaging ball portion 611 is pressed downward to a position where it does not engage with the open position engaging recess 63.

[0107] As a result, when the cable member 641b is pushed out by the control cable restriction release portion 642, the engagement ball portion 611 located on the tip side of the plunger member 61 is moved downward by one end of the cable member 641b, and is released from engagement with the open position engagement recess 63.

[0108] In this way, when the latch 241 of the handle latch mechanism part 24 is released in conjunction with the opening action of the door body 22 by operating the indoor side handle 222 or the outdoor side handle to open the door body 22, the control cable restriction release part 642 pushes the cable member 641b of the control cable 641 toward the engagement ball part 611 and presses the engagement ball part 611, thereby releasing the hold of the ventilation window 223 by the window hold release mechanism 4B.

[0109] Here, when the ventilating window 223 is in the open position, the engagement with the open position engagement recess 63 is released, and the ventilating window 223 is released from the state in which it was held in the open position. By releasing the state in which the ventilating window 223 is held in the open position, the ventilating window 223 can be closed by a closing force in the window opening / closing mechanism 3 that moves the ventilating window 223 from the open position side toward the closed position side. In this way, when the latch 241 is released in conjunction with the operation of the indoor side handle 222 to open the door body 22, the ventilating window 223 closes in conjunction with the release of the latch 241.

[0110] Next, in the third embodiment, a description will be given of the operation of the fitting 1B when the ventilating window 223 closes in conjunction with the opening operation of the door body 22. First, with the door body 22 positioned in the closed position, a user hooks their hand on the handle portion 223a of the ventilating window 223 and pulls the ventilating window 223 toward the inside of the room, thereby moving the ventilating window 223 from the closed position to the open position.

[0111] When the door body 22 is in the closed position, the engaging ball portion 611 arranged on the tip side of the plunger member 61 engages with the closed position engaging recess 62 in the closed position of the ventilation window 223. As a result, the ventilation window 223 is held in the closed position as shown in Fig. 15 by the window holding release mechanism 4B as shown in Fig. 17.

[0112] Also, even when the air intake window 223 is moved from the closed position to the open position, the engaging ball portion 611 arranged on the tip side of the plunger member 61 engages with the open position engaging recess 63 at the open position of the air intake window 223. As a result, the air intake window 223 is held by the window holding release mechanism 4B as shown in FIG. 18 in a state in which it is positioned at the open position as shown in FIG. 16.

[0113] Next, with the ventilation window 223 open, the user moves the door body 22 from the closed position to the open position. With the ventilation window 223 open, the user operates the indoor handle 222, which releases the latch 241 of the handle latch mechanism 24 in conjunction with the opening action of the door body 22 caused by the operation of the indoor handle 222 to open the door body 22. As a result, the cable member 641b of the control cable 641 is pushed toward the engaging ball portion 611 to press the engaging ball portion 611, which moves the engaging ball portion 611 downward and releases the engagement of the engaging ball portion 611 with the open position engaging recess 63.

[0114] When the engaging ball portion 611 is moved downward and disengaged from the open position engaging recess 63, the closing force of the gas spring 31 of the window opening / closing mechanism 3 causes the door end side of the ventilating window 223 to be pulled by the wire 32. As a result, the ventilating window 223 is moved from the open position to the closed position.

[0115] In this way, when the ventilating window 223 is in the open position, even if the door body 22 is moved in the closing direction, the ventilating window 223 is moved from the open position to the closed position before reaching the mullion 231 of the sleeve 23. This allows the ventilating window 223 to close in conjunction with the closing action of the door body 22. Therefore, when the door body 22 is opened, the ventilating window 223 can be prevented from getting in the way, and the ventilating window 223 can be prevented from colliding with the sleeve 23 (the mullion 231).

[0116] According to the third embodiment, in addition to the same effects as those of the second embodiment, the following effects are achieved. In the fitting 1B of this embodiment, the door body 22 is opened and closed by operating the indoor side handle 222, and has a latch 241 that is released in conjunction with the operation of the indoor side handle 222 to open the door body 22, and the ventilation window 223 closes in conjunction with the release of the latch 241 when the latch 241 is released in conjunction with the operation of the indoor side handle 222 to open the door body 22. As a result, the latch 241 is released in conjunction with the operation of the indoor side handle 222 to open the door body 22, so that the ventilation window 223 can be easily closed in conjunction with the release of the latch 241.

[0117] This embodiment also includes a window opening / closing mechanism 3 that closes the ventilating window 223 by a closing force that moves the ventilating window 223 from the open position side toward the closed position side, and a window hold release mechanism 4B that holds the ventilating window 223 in the open position and releases the hold of the ventilating window 223 when the latch 241 is released in conjunction with the operation of opening the door body 22 with the indoor side handle 222. This allows the window hold release mechanism 4B to release the hold of the ventilating window 223 by the window hold release mechanism 4B when the latch 241 is released in conjunction with the operation of opening the door body 22 with the indoor side handle 222. Therefore, with a simple configuration, the ventilating window 223 can be easily closed in conjunction with the release of the latch 241.

[0118] Moreover, in the third embodiment, unlike the first, second and fourth embodiments (described later), no additional components are added to the upper frame 211, making it possible to achieve a simpler configuration. Also, by utilizing the fact that the door body 22 is closed by releasing the latch 241 in conjunction with the operation of the indoor side handle 222 to open the door body 22, the ventilation window 223 can be closed by slightly moving the indoor side handle 222 to release the latch 241. Therefore, the ventilation window 223 can be closed more easily than by closing the door body 22 by operating the indoor side handle 222 by hand.

[0119] Next, a fourth embodiment of the fitting 1C will be described. The description of the first embodiment can be applied to the points not described in the fourth embodiment. In the fourth embodiment, the same components as those in the first embodiment are given the same reference numerals as those in the first embodiment, and the description thereof will be omitted.

[0120] As shown in Figures 20 to 22, the fitting 1C of the fourth embodiment differs from the first embodiment in that the ventilation window 223 opens and closes by rotating around the rotation axis J2 of the hinge shaft member 225 extending in the vertical direction and provided at the end on the hanging side, and in that it is equipped with a conversion mechanism 5.

[0121] The fitting 1C of the fourth embodiment does not have the friction stay 224 of the first embodiment, and the ventilation window 223 opens and closes by rotating about the rotation axis J2 of the hinge shaft member 225 (rotation shaft member) provided at the end on the hanging side.

[0122] The fitting 1C is equipped with a conversion mechanism 5. The conversion mechanism 5 converts the force for opening and closing the door body 22 into a force for closing the ventilating window 223 (window portion). As a result, the ventilating window 223 is closed by the conversion mechanism 5 in conjunction with the opening action of the door body 22.

[0123] The conversion mechanism 5 has a rotating gear 51 that rotates in conjunction with the rotation of the hinge shaft member 225 of the ventilation window 223, and a movement direction extending gear 52 that is formed extending along the movement direction of the door body 22 and meshes with the rotating gear 51.

[0124] The rotating gear 51 has a one-way clutch structure that meshes with the movement direction extension gear 52 in conjunction with the opening and closing movement of the door body 22, rotates the ventilating window 223 to the closing side when the door body 22 moves from the closed position side to the open position side, and does not rotate when the door body 22 moves from the open position side to the closed position side. As a result, the rotating gear 51 meshing with the movement direction extension gear 52 rotates in conjunction with the opening movement of the door body 22, and the ventilating window 223 closes in conjunction with the opening movement of the door body 22.

[0125] In the fourth embodiment, a description will be given of the operation of the fitting 1C when the ventilating window 223 closes in conjunction with the opening operation of the door body 22. As shown in Fig. 21, when the ventilating window 223 is open, the user moves the door body 22 from the closed position to the open position, whereby the door body 22 moves in the left-right direction toward the sleeve portion 23.

[0126] 22, the rotating gear 51, which rotates in conjunction with the rotation of the hinge shaft member 225 of the door body 22, meshes with the moving direction extending gear 52 and rotates to move the door body 22 from the open position to the closed position. As a result, the ventilation window 223 rotates about the rotation axis J2 of the hinge shaft member 225, and is moved from the open position to the closed position.

[0127] In this way, when the ventilating window 223 is in the open position, even if the door body 22 is moved in the closing direction, the ventilating window 223 is moved from the open position to the closed position before reaching the mullion 231 of the sleeve 23. This allows the ventilating window 223 to close in conjunction with the closing action of the door body 22. Therefore, when the door body 22 is opened, the ventilating window 223 can be prevented from getting in the way, and the ventilating window 223 can be prevented from colliding with the sleeve 23 (the mullion 231).

[0128] According to the fourth embodiment, the following effects are achieved. The fitting 1C of this embodiment is equipped with a conversion mechanism 5 that converts the force for opening and closing the door body 22 into a force for closing the ventilating window 223, and the ventilating window 223 is closed by the conversion mechanism 5 in conjunction with the opening operation of the door body 22. As a result, in the fitting 1C in which the openable and closable ventilating window 223 is provided in the door body 22, as in the first embodiment, the design can be improved with a simple configuration. In addition, since the ventilating window 223 closes in conjunction with the opening operation of the door body 22, it is possible to prevent the ventilating window 223 from getting in the way when the door body 22 is opened. In addition, if a sleeve portion 23 is provided in the direction in which the door body 22 is opened, it is possible to prevent the ventilating window 223 from colliding with the sleeve portion 23 when the door body 22 is opened.

[0129] In this embodiment, the conversion mechanism 5 has a rotating gear 51 that rotates in conjunction with the rotation of the hinge shaft member 225 of the ventilation window 223, and a movement direction extending gear 52 that is formed extending along the movement direction of the door body 22 and meshes with the rotating gear 51, and the ventilation window 223 closes in conjunction with the opening movement of the door body 22 as the rotating gear 51 that meshes with the movement direction extending gear 52 rotates in conjunction with the opening movement of the door body 22. This makes it possible to provide the door body 22 with the ventilation window 223 that closes in conjunction with the opening movement of the door body 22 with a simple configuration.
