JP, 2007-63824, A

Here, in the above-mentioned conventional technique, when the fully closed state is changed to the fully opened state in which the opening is fully opened by the opening/closing body, the engagement piece is rotated along with the rotation of the rotating shaft of the opening/closing mechanism. At this time, it is necessary to secure a space for not obstructing the track of the engaging piece. However, as described above, since the engaging piece is fixed immovably with respect to the rotating shaft of the opening/closing mechanism, in order to prevent the engaging piece from coming into contact with the window frame or the like of the window device, There is room for improvement from the viewpoint of downsizing the window device because there is a possibility that the space will become large.

An object of the present invention is to solve the above problems in the prior art, and it is an object of the present invention to provide a window device capable of maintaining a fully closed state while achieving a compact window device. ..

In order to solve the above-mentioned problems and to achieve the object, the window device according to claim 1 is a window device provided in an opening of a building, and a frame body provided in a peripheral edge of the opening, A window device comprising: an opening/closing body that opens and closes the opening; and an opening and closing mechanism that opens and closes the opening and closing body by performing a predetermined operation via an operating unit that constitutes the window device, The opening/closing mechanism is a shaft portion provided substantially in parallel with the opening/closing body, and the shaft portion is rotatable about the shaft portion as a rotation axis in accordance with the operation of the operating means. A pair of actuating portions, which are provided at a distance from each other with respect to the shaft portion supported with respect to the frame body, and are connected to the shaft portion and the opening/closing body, respectively, for rotating the shaft portion. With the operation of each of the pair of actuating parts, the state of the opening is switched between a fully closed state in which the opening is fully closed by the opening/closing body and a fully open state in which the opening is fully opened by the opening/closing body. A pair of possible actuating parts and a restraining means provided on the shaft part, wherein in the fully closed state, movement of the opening/closing body in the opening direction without rotation of the shaft part or opening/closing of the opening/closing body Restraining means for restraining bending so that the restraining means is slidable with respect to the shaft portion substantially along the rotation direction of the shaft portion with the rotation of the shaft portion. By attaching the restraining means to the shaft portion, rotation of the shaft portion is not hindered by the restraining means regardless of the state of the opening portion, and the shaft is restrained by the restraining means in the fully closed state. It is possible to suppress the movement of the opening/closing body toward the opening direction or the bending of the opening/closing body without rotating the part.

Since it is possible to suppress the movement of the opening/closing body or the bending of the opening/closing body, even if an external force acts on the opening/closing body in the fully closed state, the restraining means does not rotate the shaft portion toward the opening direction side of the opening/closing body. The movement or the bending of the opening/closing body can be suppressed, and the fully closed state can be maintained. Further, the suppressing means can be slidably moved with respect to the shaft portion substantially along the rotation direction of the shaft portion. For example, even if the suppressing means comes into contact with the frame body or the like from the fully closed state to the fully opened state. It is possible to prevent the rotation of the shaft portion from being obstructed by the suppressing means. Therefore, as compared with the conventional technique (the technique in which the engaging piece is immovably fixed to the rotation shaft), the space for securing the trajectory of the suppressing means accompanying the rotation of the shaft portion can be reduced. The window device can be made compact.

According to the window device of claim 3, the corresponding portion of the outer edge portion of the shaft portion corresponding to the support portion is formed in a flat shape, and the support portion is formed in a flat shape substantially along the corresponding portion of the shaft portion. Therefore, since the support portion can be formed in a flat shape, the manufacturability of the support portion can be improved as compared with the case where the support portion is formed in a curved shape. Further, for example, as compared with a case where either one of the corresponding portion of the support portion or the shaft portion is formed flat and the other of the corresponding portion of the support portion or the shaft portion is formed non-flat, the locking portion Also, the support portion can smoothly slide and move with respect to the shaft portion, and stable slide movement can be performed.

According to the window device of claim 4, a corresponding portion of the outer edge portion of the shaft portion corresponding to the support portion is formed in a substantially curved shape, and the support portion is substantially curved so as to substantially follow the corresponding portion of the shaft portion. Since it is formed in the support portion, it is easier to form a through hole capable of performing a desired amount of sliding movement of the support portion while suppressing the size of the support portion as compared with the case where the support portion is formed flat. It becomes easier to improve the usability of. Further, for example, as compared with the case where the support portion is formed in a curved shape so as not to follow the corresponding portion of the shaft portion, the locking portion and the support portion can be slid smoothly with respect to the shaft portion, and thus stable. Slide movement is possible.

According to the window device of claim 5, the locked portion is attached to the door-end side portion of the opening/closing body, and is arranged at a position that can be locked by the locking portion in the fully closed state. Since the restraint means and the opening/closing body can be securely engaged with each other, the restraining means moves the opening/closing body toward the opening direction side without rotating the shaft portion or the opening/closing body. It becomes easy to suppress bending.

Since the opening/closing body 30 is opened by operating (specifically, the first arm portion 57 rotates toward the outdoor side of the building, the rod portion 55 moves downward, etc.), 7 can be in a half open state. When the opening operation is further performed via the operation portion 51, the opening/closing body 30 is further opened by the operation of the pair of operation portions 53 in accordance with the rotation of the shaft portion 52 by the operation, and thus the opening/closing body 30 shown in FIG. It can be fully opened. Further, when the closing operation is performed via the operation portion 51 in the fully opened state of FIG. 8, the pair of operation portions 53 are activated along with the rotation of the shaft portion 52 by the operation (specifically, the first operation portion 53). Since the arm portion 57 rotates toward the indoor side of the building and the rod portion 55 moves upward), the opening/closing body 30 is closed, so that the half-opened state of FIG. 7 can be obtained. Further, when a closing operation is performed via the operation portion 51, the opening/closing body 30 is further closed by the operation of the pair of operating portions 53 in accordance with the rotation of the shaft portion 52 by the operation, and thus the opening/closing body 30 of FIG.

More specifically, a washer portion (specifically, a washer portion having a thickness larger than the thickness of the support portion 62) is inserted into each through hole 64, and the attachment portion is attached to the washer portion in the inserted state. By inserting the shaft portion of 63, the support portion 62 is arranged so as not to contact the head portion of the mounting portion 63. However, without being limited to this, for example, the support portion 62 may be disposed simply with a space from the head portion of the attachment portion 63 without providing the washer portion. The through hole 64 is a long hole that is long in the up-down direction, and slides with respect to the shaft portion 52 of the locking portion 61 and the support portion 62 when either the fully closed state or the fully opened state reaches the other. It is set as a long hole that can be moved. More specifically, in the fully closed state of FIG. 6, the mounting portion 63 and the portion of the support portion 62 corresponding to the upper end of the through hole 64 can contact, and in the fully opened state of FIG. The portion 62 is formed in a long hole shape so that a portion corresponding to the lower end of the through hole 64 can come into contact with the portion 62. Further, the mounting portion 63 and the washer portion are set to a size that enables the locking portion 61 and the support portion 62 to slide relative to the shaft portion 52. More specifically, the diameter of each of the mounting portion 63 and the washer portion is set to be shorter than the length of the through hole 64 in the lateral direction.

The bending of the opening/closing body 30 can be suppressed, and the fully closed state can be maintained. Further, the suppressing portion 60 can be slidably moved with respect to the shaft portion 52 substantially along the rotation direction of the shaft portion 52, and for example, the suppressing means can be used as the suppressing means from the fully closed state to the fully opened state. It is possible to prevent the rotation of the shaft portion 52 from being hindered by the suppressing portion 60 even if the shaft portion 52 comes into contact with the above. Therefore, as compared with the conventional technique (the technique in which the engaging piece is fixed immovably with respect to the rotating shaft), the space for securing the trajectory of the suppressing portion 60 accompanying the rotation of the shaft portion 52 can be reduced. Therefore, the window device 1 can be made compact. Further, since the suppressing portion 60 is configured by including the above-described locking portion 61, the supporting portion 62, and the mounting portion 63, the suppressing portion 60 can be configured with a simple structure, and the manufacturability of the suppressing portion 60 is improved.

It is attached to a lower end portion of the frame member 31d) by a fixture. Further, the locked portion 65 is a steel plate-shaped member configured such that the cross-sectional shape along the YZ plane is an inverted L shape. Specifically, as shown in FIGS. 4 and 10, the locked portion 65 includes a first locked side piece 65a which is arranged substantially horizontally and is attached to the first horizontal frame member 31d, and a first locked side piece 65a. A second locked side piece 65b that projects downward from the locked side (in FIG. 10, a second locked side piece that projects perpendicularly to the first locked side piece 65a). Side piece 65b). Further, as shown in FIG. 10, an insertion hole 65c for inserting the fixture is formed in the first locked side piece 65a.

The specific size of the locked portion 65 is arbitrary, but is set as follows in the embodiment. That is, as shown in FIGS. 4 and 10, the length of the locked portion 65 in the left-right direction is set to be shorter than the length of the shaft portion 52 in the left-right direction. However, without being limited to this, for example, the length of the shaft portion 52 in the left-right direction may be set to be substantially the same. Further, the length of the locked portion 65 in the front-rear direction is set to be shorter (or longer) than the length of the shaft portion 52 in the front-rear direction, for example. The length of the locked portion 65 in the vertical direction is set to a length that allows the locked portion 65 to be locked by the second locking side piece 61b. For example, the length of the shaft portion 52 in the vertical direction. It is set shorter than that.

Further, the method of installing the locked portion 65 is arbitrary, but in the embodiment, it is installed (arranged) at a position where it can be locked by the locking portion 61 in the fully closed state. More specifically, as shown in FIG. 4, in the fully closed state, the second locked side piece 65b of the locked portion 65 is closer to the outdoor side of the building than the second locked side piece 61b of the locking portion 61. Is arranged so as to be located close to (or in contact with) the second locking side piece 61b at the position of, and the first locked side piece 65a of the locked portion 65 is the second engaging portion of the locking portion 61. It is arranged so as to be located close to (or in contact with) the stop side piece 61b.

With the third feature as described above, the restraint portion 60 and the opening/closing body 30 can be securely locked, and the restraint portion 60 moves the opening/closing body 30 in the opening direction side without rotating the shaft portion 52. Alternatively, it becomes easier to suppress the bending of the opening/closing body 30.

(About the operation of the window device)
Next, the operation of the window device 1 configured as described above will be described. The operation of the window device 1 includes an operation corresponding to the fully closed state (hereinafter, referred to as "fully closed operation") and an operation for switching from the fully closed state to the fully open state (hereinafter, referred to as "first switching operation"). , And the action of switching from the fully open state to the fully closed state (hereinafter, referred to as “second switching action”). Hereinafter, each of the fully-closed action, the first switching action, and the second switching action will be described.

(About action of window device-fully closed action)
First, the fully closed operation will be described.

That is, for example, when a fire occurs around the window device 1 and in the outdoor side of the building in the fully closed state, the heat of the fire causes the opening/closing body 30 to open without rotating the shaft portion 52. When attempting to move or attempting to bend toward the open side, the locking portion 61 and the locked portion 65 are locked, so that movement of the opening/closing body 30 or bending of the opening/closing body 30 is suppressed. .. Furthermore, in the fully closed state, when the opening/closing body 30 tries to bend toward the door end side (specifically, the lower side) without the rotation of the shaft portion 52 due to the heat of the fire, the locking portion 61 and the covered portion are covered. The contact of the locking portion 65 suppresses the bending of the opening/closing body 30. Due to these, for example, the gap formed between the opening/closing body 30 and the door-side first horizontal frame member 14 due to the movement of the opening/closing body 30 or the bending of the opening/closing body 30 becomes a fire path. As a result, it is possible to prevent the fire flame from flowing into the indoor side of the building and prevent the spread of the fire.

(About operation of window device-first switching operation)
Next, the first switching action will be described.

That is, when the user performs a predetermined operation via the operation unit 51 of the opening/closing mechanism 50, each of the pair of actuating units 53 is actuated in accordance with the rotation of the shaft 52, so that the state of the opening 3 is changed. The fully closed state of 6 is switched to the fully opened state of FIG. In this case, the locking portion 61 and the support portion 62 slide with respect to the shaft portion 52 substantially along the rotation direction of the shaft portion 52 as the shaft portion 52 rotates. Specifically, in the fully closed state of FIG. 6, the mounting portion 63 and the portion of the support portion 62 corresponding to the upper end of the through hole 64 are in contact with each other. It slides so that the portion of the through hole 64 corresponding to the lower end of the through hole 64 abuts. Regarding the amount of movement of this sliding movement, although the amount of movement is small until the locking portion 61 and the body side portion 14d of the door-side first horizontal frame member 14 come into contact with each other, The amount of movement increases after contact with the body side portion 14d. By such a sliding movement, the above switching can be reliably performed without hindering the rotation of the shaft portion 52.

(About operation of window device-second switching operation)
Next, the second switching action will be described.

That is, when the user performs a predetermined operation via the operation unit 51 of the opening/closing mechanism 50, each of the pair of actuating units 53 is actuated in accordance with the rotation of the shaft 52, so that the state of the opening 3 is changed. The fully open state of 8 is switched to the fully closed state of FIG. In this case, the locking portion 61 and the support portion 62 slide with respect to the shaft portion 52 substantially along the rotation direction of the shaft portion 52 as the shaft portion 52 rotates. Specifically, when the mounting portion 63 and the portion of the support portion 62 corresponding to the lower end of the through hole 64 are in contact with each other in the fully opened state of FIG. 8, the mounting portion 63 and the support portion are in the fully closed state of FIG. The slide movement is performed so that the portion of the through hole 64 corresponding to the upper end of the through hole 64 abuts. Regarding the amount of movement of this sliding movement, the amount of movement is large until the locking portion 61 and the body side portion 14d do not come into contact with each other, but the locking portion 61 and the body side portion 14d do not come into contact with each other. The amount of movement from is small. By such a sliding movement, the above switching can be reliably performed without hindering the rotation of the shaft portion 52.

(Effects of the embodiment)
As described above, according to the embodiment, the suppressing portion 60 is configured to be slidable with respect to the shaft portion 52 substantially along the rotation direction of the shaft portion 52 with the rotation of the shaft portion 52. By attaching 60 to the shaft portion 52, the rotation of the shaft portion 52 is not hindered by the suppressing portion 60 regardless of the state of the opening portion 3, and the rotation of the shaft portion 52 is performed by the suppressing portion 60 in the fully closed state. Since it is possible to suppress the movement of the opening/closing body 30 toward the opening direction side or the bending of the opening/closing body 30 without causing the opening/closing body 30, even if an external force acts on the opening/closing body 30 in the fully closed state, the suppressing portion 60 causes the shaft portion 52 It is possible to suppress the movement of the opening/closing body 30 toward the opening direction or the bending of the opening/closing body 30 without the rotation of, and it is possible to maintain the fully closed state. Further, the suppressing portion 60 can be slidably moved with respect to the shaft portion 52 substantially along the rotation direction of the shaft portion 52, and for example, the suppressing portion 60 becomes a frame body or the like from the fully closed state to the fully opened state. Even if they come into contact with each other, it is possible to prevent the rotation of the shaft portion 52 from being hindered by the suppressing portion 60. Therefore, as compared with the conventional technique (the technique in which the engaging piece is fixed immovably with respect to the rotating shaft), the space for securing the trajectory of the suppressing portion 60 accompanying the rotation of the shaft portion 52 can be reduced. Therefore, the window device 1 can be made compact.

Further, the suppressing portion 60 is inserted into the locking portion 61 that can lock the opening/closing body 30 in the fully closed state, the support portion 62 that supports the locking portion 61, and the through hole 64 provided in the support portion 62. The mounting portion 63 is provided so that the locking portion 61 and the support portion 62 can slide relative to the shaft portion 52 substantially along the rotation direction of the shaft portion 52 as the shaft portion 52 rotates. In addition, since the support portion 62, the through hole 64, and the attachment portion 63 are configured, the suppressing portion 60 can be configured with a simple structure and the manufacturability of the suppressing portion 60 can be improved.
