[0014] As shown in FIGS. 4 to 6, two setting blocks 5 as panel holding parts and two anti-drop parts 6 are respectively attached to the panel mounting grooves 321A, 421A of the lower frames 32, 42. The two setting blocks 5 are attached so as to be positioned between the two anti-drop parts 6. Details of the configuration and mounting structure of the setting blocks 5 and the anti-drop parts 6 will be described later.

[0015] The panel mounting grooves 321A and 421A are composed of bottoms 321B and 421B extending in the Z-axis direction, and a pair of side portions 321C and 421C extending upward from both ends of the bottoms 321B and 421B in the Z-axis direction. The bottoms 321B and 421B are composed of outdoor-side bottoms 321D and 421D located on the outdoor side, and indoor-side bottoms 321E and 421E located on the indoor side and having an upper surface at a position higher than the upper surface of the outdoor-side bottoms 321D and 421D.

[0016] At the center of the outdoor-side bottoms 321D and 421D in the Z-axis direction, screw hole forming portions 321F and 421F protruding upward are provided. Screws for fixing the metal frame members 331 and 431 of the door edge frames 33 and 43 and the metal frame members 341 and 441 of the calling frames 34 and 44 to the metal frame members 321 and 421 of the lower frames 32 and 42 are screwed into the screw holes of the screw hole forming portions 321F and 421F, respectively. At the upper ends on the indoor side of the screw hole forming portions 321F and 421F, first locked portions 321G and 421G protruding toward the indoor side are provided. Drain holes 321H and 421H are provided at portions located between the setting blocks 5 and the fall prevention parts 6 in the outdoor-side bottoms 321D and 421D by cutting out the screw hole forming portions 321F and 421F so as to penetrate the indoor-side bottoms 321E and 421E. Note that the drain holes 321H and 421H may be formed below the fall prevention parts 6. Locked pieces 321J and 421J extending upward are provided on the outdoor side of the indoor-side bottoms 321E and 421E. The upper ends of the locked pieces 321J and 421J are located at substantially the same height as the upper ends of the screw hole forming portions 321F and 421F. Second locked portions 321K and 421K protruding toward the outdoor side are provided at the upper ends of the locked pieces 321J and 421J. That is, the first locked portions 321G and 421G and the second locked portions 321K and 421K protrude in directions approaching each other. In the portion located between the setting block 5 and the anti-drop component 6 at the indoor-side bottom 321E and 421E, drainage notches 321L and 421L are formed by cutting notches in the engaged pieces 321J and 421J so as not to penetrate the indoor-side bottom 321E and 421E. Note that the drainage notches 321L and 421L may be formed below the anti-drop component 6. Further, as shown in FIG. 4, the drainage notches 321L and 421L may be formed at positions facing the drainage holes 321H and 421H in the Z-axis direction, or may be formed at positions not facing the Z-axis direction. On the lower end sides of the opposing surfaces of the pair of side portions 321C and 421C, heating foams 39 and 49 are respectively attached.

[0017] The setting block 5 is formed of EPDM (ethylene propylene rubber) or the like, and includes a first block load receiving portion 51 located on the outdoor side, a second block load receiving portion 52 located on the indoor side, and a connecting portion 53 connecting the upper end portions of the first block load receiving portion 51 and the second block load receiving portion 52. The lower surface of the first block load receiving portion 51 constitutes an outdoor-side contact surface 54 that abuts on the upper ends of the screw hole forming portions 321F and 421F. On the indoor side of the outdoor-side contact surface 54, a first block locking piece 55 extending downward is provided. At the lower end of the first block locking piece 55, a first block locking convex portion 551 protruding outward and locking to the first locked portions 321G and 421G is provided. The lower surface of the second block load receiving portion 52 is located below the outdoor-side contact surface 54 and constitutes an indoor-side contact surface 56 that abuts on the indoor-side bottom 321E and 421E. At the center of the connecting portion 53 in the Z-axis direction, a second block locking piece 57 extending downward is provided. At the lower end of the second block locking piece 57, a second block locking convex portion 571 protruding inward and locking to the second locked portions 321K and 421K is provided. The setting block 5 supports the lower ends of the panels 36 and 46 when attached to the panel mounting grooves 321A and 421A.

[0018] The anti-drop component 6 is formed of a metal such as aluminum. The anti-drop component 6 includes, for example, a main body portion 61 formed in a rectangular plate shape and a plurality of pieces extending downward from the main body portion 61. Each piece is continuously provided from one end to the other end of the main body portion 61 in the X-axis direction. The plurality of pieces include first and second attracting pieces 62 and 63, first and second locking pieces 64 and 65, and first and second load receiving pieces 66 and 67.

[0019] The first attracting piece 62 is provided at the outdoor-side side edge of the main body portion 61. On the outdoor-side surface of the first attracting piece 62, a first inclined surface 621 is provided which inclines so as to move away from the center in the expected direction of the main body portion 61, that is, to approach the outdoor side, as it goes upward from the lower end. The second attracting piece 63 is provided at the indoor-side side edge of the main body portion 61 and is formed to be shorter than the first attracting piece 62. On the indoor-side surface of the second attracting piece 63, a second inclined surface 631 is provided which inclines so as to move away from the center in the expected direction of the main body portion 61, that is, to approach the indoor side, as it goes upward from the lower end.

[0020] The first locking piece 64 is provided at a position on the outdoor side of the main body portion 61 such that the lower end is positioned above the lower end of the first attracting piece 62 and below the lower ends of the other pieces. At the lower end of the first locking piece 64, a first locking convex portion 641 is provided which protrudes to the outdoor side and locks to the first locked portions 321G and 421G. The first locking convex portion 641 includes a first locking inclined surface 641A which inclines so as to approach the indoor side as it goes downward. The second locking piece 65 is provided at the central position of the main body 61 in the Z-axis direction such that the lower end is located below the lower end of the first load-receiving piece 66 and above the lower ends of the other pieces. That is, the first and second locking pieces 64 and 65 are a pair of locking pieces arranged in the prospective direction of the present invention. At the lower end of the second locking piece 65, a second locking convex portion 651 that protrudes toward the indoor side and locks to the second locked portions 321K and 421K is provided. The second locking convex portion 651 includes a second locking inclined surface 651A that inclines so as to approach the outdoor side as it goes downward. The first locking piece 64 and the second locking piece 65 are formed such that the difference in their lengths is larger than the difference in the heights of the upper ends of the first locked portions 321G and 421G and the second locked portions 321K and 421K.

[0021] The first and second load-receiving pieces 66 and 67 are formed such that their prospective dimensions (dimensions in the Z-axis direction) are larger than the prospective dimensions of the first and second guiding pieces 62 and 63 and the first and second locking pieces 64 and 65. The first load-receiving piece 66 is provided between the first guiding piece 62 and the first locking piece 64 in the main body 61 so as to be located directly below the panels 36 and 46. The lower end surface of the first load-receiving piece 66 is located above the lower ends of the other pieces and is provided so as to be in surface contact with the upper surface of the screw hole forming portions 321F and 421F. The second load-receiving piece 67 is provided between the second guiding piece 63 and the second locking piece 65 in the main body 61 so as to be located directly below the panels 36 and 46. The lower end surface of the second load-receiving piece 67 is located above the lower ends of the first guiding piece 62 and the first locking piece 64, below the lower ends of the second guiding piece 63, the second locking piece 65, and the first load-receiving piece 66, and is provided so as to be in surface contact with the indoor side bottoms 321E and 421E.

[0022] The anti - downward movement component 6 is attached to the panel mounting grooves 321A and 421A in such a state that the first load - receiving piece 66 is in surface contact with the upper surfaces of the screw - hole forming parts 321F and 421F, the second load - receiving piece 67 is in surface contact with the indoor - side bottoms 321E and 421E, the lower end of the first locking piece 64 does not contact the outdoor - side bottoms 321D and 421D, and the lower end of the second locking piece 65 does not contact the indoor - side bottoms 321E and 421E. The anti - downward movement component 6 is attached to the panel mounting grooves 321A and 421A so that a gap is formed between it and the panels 36 and 46 supported by the setting blocks 5 when it is attached to the panel mounting grooves 321A and 421A.

[0023] Next, the method of attaching the lower frame 32 of the anti - downward movement component 6 to the panel mounting groove 321A will be described. In the following, the attachment method using an automatic attachment device will be described, but an operator may also perform the attachment. Also, the attachment method in the case where the heat - insulating and foaming materials 39 and 49 are provided in the sliding window 1 will be described, but the anti - downward movement component 6 can be attached in the same manner even when the heat - insulating and foaming materials 39 and 49 are not provided. Also, since the method of attaching the lower frame 42 of the anti - downward movement component 6 to the panel mounting groove 421A is the same as the method of attaching it to the panel mounting groove 321A, its description will be omitted.

[0024] The automatic attachment device adsorbs the upper surface of the main body part 61 of the anti - downward movement component 6 by, for example, a suction pad and moves it above the attachment position in the panel mounting groove 321A. Then, the automatic attachment device attaches the anti - downward movement component 6 to the panel mounting groove 321A by lowering the anti - downward movement component 6 while maintaining, for example, the state where the upper surface of the main body part 61 is parallel to the horizontal plane.

[0025] When the anti - dropping component 6 descends with a deviation in the Z - axis direction relative to the mounting position during this installation, the lower end of the first guiding piece 62 or the second guiding piece 63 may contact the outer - side portion 321C on the outdoor side, the upper end of the resin frame member 322, or the upper end of the heat - insulating foam material 39 on the outdoor side or the indoor side. For example, when the lower end of the first guiding piece 62 contacts the heat - insulating foam material 39, the anti - dropping component 6 is guided to the indoor side so as to correct the deviation in the Z - axis direction as the first inclined surface 621 descends while contacting the upper end of the heat - insulating foam material 39. Similarly, when the lower end of the second guiding piece 63 contacts the heat - insulating foam material 39, the anti - dropping component 6 is guided to the outdoor side so as to correct the deviation in the Z - axis direction due to the contact between the second inclined surface 631 and the heat - insulating foam material 39. Thus, by providing the first and second guiding pieces 62 and 63 for guiding the anti - dropping component 6 into the panel mounting groove 321A, even if the position of the anti - dropping component 6 in the Z - axis direction is deviated during installation, the anti - dropping component 6 can be mounted in the panel mounting groove 321A.

[0026] When the anti - dropping component 6 descends with the upper surface of the main body portion 61 being parallel to the horizontal plane, before the second locking piece 65 contacts the locked piece 321J, the first locking piece 64 contacts the screw - hole forming portion 321F. Then, as the anti - dropping component 6 descends while the first locking inclined surface 641A of the first locking piece 64 contacts the first locked portion 321G of the screw - hole forming portion 321F, the lower - end side of the first locking piece 64 deforms toward the indoor side. Further, as the anti - dropping component 6 descends, the first locking piece 64 returns to the state before deformation, and the first locking convex portion 641 is locked to the first locked portion 321G. Also, when the anti - dropping component 6 descends, the second locking piece 65 contacts the locked piece 321J. Then, as the anti - dropping component 6 descends while the second locking inclined surface 651A of the second locking piece 65 contacts the second locked portion 321K of the locked piece 321J, the lower - end side of the second locking piece 65 deforms toward the outdoor side. Further, as the anti - dropping component 6 descends, the second locking piece 65 returns to the state before deformation, and the second locking convex portion 651 is locked to the second locked portion 321K.

[0027] In this way, the anti-drop component 6 can be attached to the panel attachment groove 321A with a simple configuration that only locks the first and second locking pieces 64 and 65 to the first and second locked portions 321G and 321K.

[0028] The first locking convex portion 641 and the second locking convex portion 651 are provided so as to protrude in a direction away from each other. Therefore, even if a force to rotate the anti-drop component 6 about the first guiding piece 62 (the outdoor-side end) acts on the anti-drop component 6, the second locking convex portion 651 is farther from the fulcrum than the first locking convex portion 641 and the moving distance per unit rotation angle is longer than that of the first locking convex portion 641, making it difficult to release the locking between the second locking convex portion 651 and the second locked portion 321K. Conversely, even if a force to rotate the anti-drop component 6 about the second guiding piece 63 (the indoor-side end) acts on the anti-drop component 6, the first locking convex portion 641, whose moving distance per unit rotation angle is longer than that of the second locking convex portion 651, makes it difficult to release the locking with the first locked portion 321G. Therefore, it is possible to prevent the anti-drop component 6 from accidentally coming off the panel attachment groove 321A.

[0029] Since the first locking piece 64 is longer than the second locking piece 65 and the height positions of the upper ends of the screw hole forming portion 321F and the locked piece 321J are substantially the same, during the period when the first locking piece 64 is deformed by contact with the first locked portion 321G, in at least a part of the period including the start of deformation, the second locking piece 65 is not in contact with the locked piece 321J and is not deformed. Therefore, compared with the case where the lengths of the first locking piece 64 and the second locking piece 65 are made the same and the first locking piece 64 and the second locking piece 65 are deformed simultaneously, the force to lower the anti-drop component 6 can be reduced.

[0030] The first locked portion 321G to which the first locking convex portion 641 is locked is provided in the screw hole forming portion 321F into which the screw is screwed. Therefore, compared with the case of providing a locking piece having the first locked portion 321G without providing the first locked portion 321G in the screw hole forming portion 321F, the configuration of the lower frame 32 can be simplified.

[0031] Next, the operation during a fire will be described. When the temperature rises during a fire, the heat-expandable materials 39 and 49 expand. Also, the setting blocks 5 that support the panels 36 and 46 soften, and the panels 36 and 46 come into contact with the main body 61 of the downward prevention part 6 made of metal. At this time, the loads of the panels 36 and 46 are received by the first load receiving pieces 66 and the second load receiving pieces 67 that are respectively in contact with the screw hole forming part 321F and the indoor side bottom part 321E. Therefore, it is possible to suppress the breakage of the first and second locking pieces 64 and 65 due to the loads of the panels 36 and 46. Also, the expected dimensions of the first and second load receiving pieces 66 and 67 are larger, that is, thicker than those of the other pieces (the first and second guiding pieces 62 and 63, the first and second locking pieces 64 and 65). For this reason, it is possible to suppress the breakage of the first and second load receiving pieces 66 and 67, and it is possible to suppress the further downward movement of the panels 36 and 46. Also, since the first and second locking pieces 64 and 65 are not in contact with the outdoor side bottom part 321D and the indoor side bottom part 321E, it is possible to prevent the loads of the panels 36 and 46 from acting on the first and second locking pieces 64 and 65, and it is possible to prevent the breakage of the first and second locking pieces 64 and 65.

[0032] [Modification Example] Although a configuration in which two sets of a locking piece and a locked part (the sets of the first and second locking pieces 64 and 65 and the first and second locked parts 321G and 321K) are provided in the downward prevention part 6 has been illustrated, one set or three or more sets may be provided. Although a configuration in which the first locking convex part 641 and the second locking convex part 651 are provided so as to project in a direction away from each other has been illustrated, they may be provided so as to project in a direction approaching each other or in the same direction, and the first and second locked parts 321G and 321K may be provided so as to be locked to the first and second locking convex parts 641 and 651 provided in this way. The first and second locked parts 321G and 321K may be provided. The first locking piece 64 may have the same length as the second locking piece 65. Also, the first locking piece 64 may be made to have the same length as the second locking piece 65, and the height positions of the screw hole forming portion 321F and the upper end of the locked piece 321J may be made different. When the fall prevention component 6 is attached to the panel attachment grooves 321A, 421A, the first locking piece 64 may be configured to contact the outdoor side bottom portions 321D, 421D, or the second locking piece 65 may be configured to contact the indoor side bottom portions 321E, 421E.

[0033] Although an example of the configuration in which two load receiving pieces (the first and second load receiving pieces 66, 67) are provided on the fall prevention component 6 has been illustrated, it is not necessary to provide any, or one or three or more may be provided. The expected dimensions of the first and second load receiving pieces 66, 67 may be the same as those of the other pieces. It is not necessary to provide at least one of the first and second guiding pieces 62, 63 on the fall prevention component 6. Instead of providing the first locked portion 321G in the screw hole forming portion 321F, a locking piece having the first locked portion 321G may be provided.

[0034] In the above embodiment, the fall prevention component 6 is applied to the configuration in which the panels 36, 46 are held by the backup materials 37A, 47A, the sealing materials 37B, 47B, and the setting blocks 5. However, as shown in FIG. 7, the fall prevention component 6 may be applied to the configuration in which the panels 36A, 46A are held by the gasket 7 as the panel holding portion. Although the fall prevention component 6 has been applied to the sliding window 1, it may be applied to prevent the panels of a single - hung window or a FIX window from falling.

[0035] [Summary of the Invention] The anti-drop component of the present invention is arranged in a panel mounting groove provided in a frame body, and is an anti-drop component for preventing a panel mounted in the panel mounting groove from dropping. The anti-drop component includes a main body portion facing the lower end of the panel, and a plurality of pieces extending downward from a plurality of locations in the prospective direction of the main body portion. The plurality of pieces include locking pieces that lock to a locked portion provided at the bottom of the panel mounting groove. According to the present invention, the anti-drop component can be attached to the panel mounting groove with a simple configuration that only locks the locking piece to the locked portion.

[0036] In the anti-drop component of the present invention, the plurality of pieces preferably include a pair of the locking pieces arranged in the prospective direction, and each of the locking pieces is provided with a locking convex portion protruding in a direction away from each other. According to the present invention, even when a force for rotating the anti-drop component with one side in the prospective direction as a fulcrum acts, the moving distance per unit rotation angle of the locking convex portion on the side far from the fulcrum (the other side) is longer than that of the locking convex portion on the side close to the fulcrum (one side), making it difficult to release the locking between the locking convex portion on the other side and the locked portion on the other side. Conversely, even when a force for rotating the anti-drop component with the other side in the prospective direction as a fulcrum acts, the moving distance per unit rotation angle of the locking convex portion on the one side is longer than that of the locking convex portion on the other side, making it difficult to release the locking between the locking convex portion on the one side and the locked portion on the one side. Therefore, it is possible to suppress the anti-drop component from accidentally coming off the panel mounting groove.

[0037] In the anti-drop component of the present invention, each of the locking convex portions is provided at the lower end of each of the locking pieces. One of the locking pieces is longer than the other locking piece, and the height positions of the upper ends of a pair of the locked portions locked by each of the locking pieces are preferably the same. According to the present invention, in order to attach the anti-drop component to the panel mounting groove, when the anti-drop component is lowered in a posture where the lower end of one locking piece is located below the lower end of the other locking piece, during the period when one locking piece is deformed by contact with the locked portion, at least a part of the period including the start of deformation, the other locking piece is not in contact with the locked piece and is not deformed. For this reason, compared with the case where the lengths of the respective locking pieces are made the same and the respective locking pieces are deformed simultaneously, the force for lowering the anti-drop component can be reduced.

[0038] In the anti-drop component of the present invention, it is preferable that the plurality of pieces include load-receiving pieces that receive the load of the panel by abutting against the bottom portion. According to the present invention, it is possible to suppress breakage of the locking piece due to the load of the panel.

[0039] In the anti-drop component of the present invention, it is preferable that the load-receiving piece is formed such that an expected dimension is larger than an expected dimension of the locking piece and is provided so as to be located directly below the panel. According to the present invention, it is possible to suppress breakage of the load-receiving piece and suppress further lowering of the panel.

[0040] In the anti-drop component of the present invention, it is preferable that the locking piece is configured not to contact the bottom portion in a state where the load-receiving piece is in contact with the bottom portion. According to the present invention, it is possible to prevent the load of the panel from acting on the locking piece and prevent breakage of the locking piece.

[0041] In the anti-drop component of the present invention, the plurality of pieces are provided so as to extend downward from an end portion in the expected direction of the main body portion, and include guiding pieces for guiding the anti-drop component into the panel mounting groove. The guiding pieces are provided with inclined surfaces that incline away from the center in the expected direction of the main body portion as they go upward from the lower ends. According to the present invention, even if the position of the fall-preventing component in the expected direction is displaced during installation, the fall-preventing component can be easily attached to the panel attachment groove.

[0042] The fitting of the present invention includes a frame body provided with a panel attachment groove, a panel attached to the panel attachment groove, a panel holding portion disposed in the panel attachment groove provided in the lower frame of the frame body for holding the panel, and the above-described fall-preventing component disposed in the panel attachment groove provided in the lower frame for preventing the panel from falling. A screw hole forming portion into which a screw is screwed is provided at the bottom of the panel attachment groove, and a portion to be locked with the locking piece of the fall-preventing component is provided on the outer periphery of the screw hole forming portion. According to the present invention, the configuration of the frame body can be simplified as compared with the case where a locking piece having a portion to be locked is provided without providing the portion to be locked in the screw hole forming portion.
