Modes for Carrying Out the Invention

[0008] [Embodiment] The opening device of the present invention will be described by taking a vertical sliding window as an example. In the following description, the same reference numerals in different figures denote parts having the same function, and duplicate descriptions in each figure will be omitted as appropriate.

[0009] [Configuration of the Vertical Sliding Window] FIG. 1 is a longitudinal sectional view and a cross-sectional view in the closed state of the vertical sliding window according to the present embodiment of the present invention, and FIG. 2 is a longitudinal sectional view and a cross-sectional view in the 90° open and fixed state of the vertical sliding window according to an embodiment of the present invention. As shown in FIGS. 1 and 2, the vertical sliding window is composed of a frame 1 fixed to an opening of a building and a door 2 attached to the frame 1 so as to open toward the outdoor side. The door 2 has a glass panel 3 fitted therein and is supported by a known support mechanism 4 so as to be slidable and openable / closable with respect to the frame 1. Since the support mechanism 4 is well-known, a detailed description thereof will be omitted.

[0010] [Frame Body] The frame 1 is composed of a pair of upper frames 11 and lower frames 12 arranged opposite to each other, and a pair of left vertical frames 13 and right vertical frames 14 arranged opposite to each other, which are combined in a rectangular shape. The upper frame 11 is composed of an upper metal frame 11a made of an aluminum extrusion profile or the like, and an upper resin frame 11b attached to the indoor side and the inner peripheral side of the upper metal frame 11a. The lower frame 12 is composed of a lower metal frame 12a made of an aluminum extrusion profile or the like, and a lower resin frame 12b attached to the indoor side and the inner peripheral side of the lower metal frame 12a. The left vertical frame 13 is composed of a left vertical metal frame 13a made of an aluminum extrusion profile or the like, and a left vertical resin frame 13b attached to the indoor side and the inner peripheral side of the left vertical metal frame 13a. The right vertical frame 14 is composed of a right vertical metal frame 14a made of an aluminum extrusion profile or the like, and a right vertical resin frame 14b attached to the indoor side and the inner peripheral side of the right vertical metal frame 14a.

[0011] [Door] The door 2 is composed of a pair of upper frames 21 and lower frames 22 arranged opposite to each other, and a pair of left vertical frames 23 and right vertical frames 24 arranged opposite to each other, which are combined in a rectangular shape, and a glass panel 3 is arranged on its inner periphery. The upper frame 21 is composed of an upper metal frame 21a made of an aluminum extrusion profile or the like, and an upper resin frame 21b attached to the indoor side of the upper metal frame 21a. The lower frame 22 is composed of a lower metal frame 22a made of an aluminum extrusion profile or the like, and a lower resin frame 22b attached to the indoor side of the lower metal frame 22a. The left vertical frame 23 is composed of a left vertical metal frame 23a made of an aluminum extrusion profile or the like, and a left vertical resin frame 23b attached to the indoor side of the left vertical metal frame 23a. The right vertical frame 24 is composed of a right vertical metal frame 24a made of an aluminum extrusion profile or the like, and a right vertical resin frame 24b attached to the indoor side of the right vertical metal frame 24a.

[0012] Between the upper metal frame 11a and the upper end of the left vertical metal frame 23a, and between the lower metal frame 12a and the lower end of the left vertical metal frame 23a, a support mechanism 4 for supporting the door 2 to be openable and closable with respect to the frame 1 is attached respectively. In this embodiment, the door 2 is supported to be openable and closable between a closed state and a 90° open state where it is opened up to 90° toward the outdoor side. The door 2 can be locked in the closed state by the handle 6. In the closed and locked state, the handle 6 is rotated to release the lock, and then the door 2 can be rotated outward by the handle 6 as it is. Further, the open door 2 can be rotated inward by the handle 6 to be in the closed state, and then the handle 6 can be rotated to lock it as it is.

[0013] [Door fixing member] A door fixing member 5 for fixing the door 2 in the 90° open state and making it non - closable is attached to the lower metal frame outdoor side edge portion 12a1 which is the outdoor side edge portion of the lower metal frame 12a. The door fixing member 5 is attached below the outdoor side surface of the left vertical metal frame 23a on the lower metal frame outdoor side edge portion 12a1. The door fixing member 5 has a fixing piece 51 attached on the lower metal frame outdoor side edge portion 12a1, and a rotating piece 52 rotatably attached to a rotating shaft 53 provided at one end side in the finding direction of the fixing piece 51. The lower metal frame outdoor side edge portion 12a1 is formed to be one - step lower than other parts of the lower metal frame 12a, and the height of the fixing piece 51 fixed on the lower metal frame outdoor side edge portion 12a1 is designed so that its upper surface does not become higher than other parts of the lower metal frame 12a. And the upper surface of the fixing piece 51 is provided so as to be positioned below the lowermost parts of the left vertical frame 23 and the lower frame 22 of the door 2. The fixing piece 51 is outside the rotation locus of the door 2 and does not hinder the opening and closing of the door 2.

[0014] The rotating piece 52 rotates about the rotating shaft 53 between a position (retracted position) placed on the lower metal frame outdoor side edge portion 12a1 beside the fixing piece 51 and a position (projected position) placed on the upper surface of the fixing piece 51. When the rotating piece 52 is in the retracted position, the upper surface of the rotating piece 52 is designed to be located at least below the upper surface of the fixed piece 51. Thereby, in the retracted position of the rotating piece 52, the upper surface of the rotating piece 52 is located below the lowermost part of the left vertical frame 23 and the lower frame 22 of the door 2, and the rotating piece 52 is outside the rotation locus of the door 2 and does not become an obstacle to the opening and closing of the door 2.

[0015] On the other hand, when the rotating piece 52 is in the protruding position, the upper surface (the lower surface in the retracted position) of the rotating piece 52 is located above the upper surface of the fixed piece 51. At this time, at least a part of the rotating piece 52 is located above the lowermost part of the left vertical frame 23. When the door 2 is in the 90° open state, the prospective surface of the rotating piece 52 in the protruding position can be in contact with the outdoor side surface 23a1 of the lower part of the left vertical metal frame 23a as the contact surface 52a.

[0016] In this embodiment, the door fixing member 5 is attached to the outdoor side edge portion 12a1 of the lower metal frame so that there is a slight gap as a margin between the contact surface 52a of the rotating piece 52 and the outdoor side surface 23a1 of the left vertical metal frame. Further, in this embodiment, the door fixing member 5 is configured such that the rotating piece 52 of the door fixing member 5 cannot be rotated to the protruding position when the door 2 is in a state other than the 90° open state. The specific dimension of this gap can be appropriately determined in consideration of design errors, construction errors, etc., and it is also possible to prevent the gap from occurring. Also, at any position other than when the door 2 is in the 90° open state, the rotating piece 52 of the door fixing member 5 may be configured to be rotatable to the protruding position.

[0017] The outdoor side surface 23a1 of the left vertical metal frame of the door 2 is the prospective surface in the 90° open state. In the protruding state, the contact surface 52a of the rotating piece 52 is configured to contact the outdoor side surface 23a1 of the left vertical metal frame of the door 2 in the 90° open state from the finding direction, preventing the support mechanism 4 from sliding in the finding direction and the door 2 from rotating. In this way, by preventing the support mechanism 4 from sliding in the finding direction and the rotation of the door 2, the door 2 can be fixed.

[0018] In this embodiment, as the door fixing member 5, a structure is used in which a rotating piece 52 is rotatably connected to a fixing piece 51 and the rotating piece 52 rotates on the upper surface of the fixing piece 51. However, any structure can be used as long as it can protrude and retract between a protruding position inside the rotation locus of the door and a retracted position outside the rotation locus. For example, when pressed and released at the protruding position, it is pushed in and held at the retracted position, and when pressed and released at the retracted position, it pops out and is held at the protruding position; or when pressed and released at the protruding position, it is pushed in and held at the retracted position, and when pulled at the retracted position, it pops out and is held at the protruding position. Examples include those that can be held at two positions, the retracted position and the protruding position, with simple operations.

[0019] [Door Fixing Operation] FIG. 3 is a perspective view schematically showing, respectively, (a) an open and unfixed state and (b) an open and fixed state of the vertical sliding window according to the embodiment of the present invention. When the door 2 is in an open state, it is necessary to fix the door 2 in order to prevent the door 2 from swinging unintentionally due to wind or the like. Therefore, in a state where the door 2 is opened to the maximum (a state where it does not rotate further in the opening direction), the door fixing member 5 that fixes the door 2 so that it does not rotate in the closing direction is operated. First, the door 2 is rotated to a 90° open state, which is the maximum open state (see FIG. 3(a)). During rotation, the rotating piece 52 of the door fixing member 5 is in the retracted position and does not obstruct the rotation of the door 2. Next, the rotating piece 52 of the door fixing member 5 is rotated so as to be placed on the upper surface of the fixing piece 51 (see FIG. 3(b)). Then, the contact surface 52a of the rotating piece 52 can come into contact with the outer side surface 23a1 of the left vertical metal frame from the finding direction, and the rotation of the door 2 can be prevented. In this way, by using the door fixing member 5 with a simple structure in which only the rotating piece 52 is rotatably attached to the fixing piece 51, and by rotating the rotating piece 52 with a simple operation of protruding and retracting between a protruding position inside the rotation locus of the door 2 and a retracted position outside the rotation locus, the door 2 can be fixed and unfixed in a 90° open state.

[0020] In this embodiment, the door fixing member 5 fixes the door 2 by preventing the sliding movement of the support mechanism 4 in the finding direction and the rotation of the door 2. However, the door 2 may be configured to be fixed only by preventing the rotation of the door 2. For example, the door fixing member 5 may be attached at a position where it abuts on the prospective surface of the left vertical metal frame 23a (facing the indoor side in the 90° open state of the door 2) from the indoor side to prevent the door 2 from rotating.

[0021] [Modification Example] A modification example of the present invention will be described with reference to FIG. 4. FIG. 4 is a cross-sectional view of the vertical sliding window according to the modification example of the present invention in (a) the closed state and (b) the open and fixed state. In this modification example, the door 2 is supported so as to be openable and closable between the closed state and the 60° open state in which it is opened up to 60° toward the outdoor side. In this modification example, the outdoor side surface 23a1 of the left vertical metal frame of the door 2 is located outside the outdoor side edge portion 12a1 of the lower metal frame in the 60° open state, and it is difficult to arrange the door fixing member 5 so as to abut on the outdoor side surface 23a1 of the left vertical metal frame. Therefore, when the door 2 is in the 60° open state, the rotating piece 52' is configured to be able to abut on the prospective surface 23a2 of the lower part of the left vertical metal frame 23a, which is the prospective surface of the left vertical metal frame. Therefore, the contact surface 52a' of the rotating piece 52' is formed as an inclined surface that forms an angle of 30° with respect to the finding direction. The rotating piece 52 is in the protruding position, and its contact surface 52a' abuts on the prospective surface 23a2 of the left vertical metal frame of the door 2 in the 60° open state from the indoor side, preventing the support mechanism 4 from sliding in the finding direction and the door 2 from rotating, thereby fixing the door 2.

[0022] As described above, in the embodiment and the modification example according to the present invention, by using the door fixing member 5 having a simple structure, the door 2 can be switched between the fixed state and the non-fixed state in the open state by a simple operation in which the rotating piece 52' protrudes and retracts between the protruding position inside the rotation locus of the door 2 and the retracted position outside the rotation locus.

[0023] As described above, the embodiments and modifications of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments, and design changes and the like within the scope not departing from the gist of the present invention are also included in the present invention. In addition, as long as there are no particular contradictions or problems in the purpose and configuration of the above-described embodiments and modifications, it is possible to combine them by diverting each other's technologies.
