[0009] An example of an opening device in an embodiment will be described with reference to the drawings, using an example of an opening device that includes a ventilation device 5 between the building opening and the frame 1 of a sliding window.

[0010] (Sliding window) As shown in Figures 1 to 3, the opening device of this embodiment comprises a frame 1, inner and outer sashes 2 and 3, and a ventilation device 5 positioned between the frame 1 and the building opening.

[0011] The frame 1 is made of resin material and is formed by arranging an upper frame 11 and a lower frame 12 between left and right vertical frames 13 and 14. Upper rails 11a, 11b and lower rails 12a, 12b are provided on the upper frame 11 and the lower frame 12 to guide the inner and outer sashes 2 and 3.

[0012] The inner and outer sliding doors 2 and 3 are formed by fitting panels 25 and 35, such as double-glazed glass, into the inner circumference of a frame body which is made up of upper frames 21 and 31, lower frames 22 and 32 and left and right vertical frames 23, 24, 33 and 34 made of resin material, and are supported so as to be able to open and close by being guided by the upper rails 11a and 11b and lower rails 12a and 12b of the frame body 1.

[0013] (Ventilation system) As shown in Figures 2, 4, and 5, the ventilation device 5, positioned between the building opening and the frame 1, includes an opening-side member 51 positioned on the inner circumference of the building opening, a frame-side member 52 positioned on the outer circumference of the frame 1, and a column member 53 positioned between the opening-side member 51 and the frame-side member 52.

[0014] As shown in Figures 5(a) and 5(b), the opening-side member 51 of the ventilation device 5 has an opening-side main body 511 that is arranged along the inner circumferential surface of the building opening, and an outer-side cover (outer-side cover portion) 512 provided at the indoor-side end of the opening-side main body 511.

[0015] The opening-side main body 511 of the opening-side member 51 is made of a metal material such as aluminum alloy, and has a recessed wall portion 511a having a depth dimension similar to that of the frame 1, and a flow-straightening recessed wall portion 511b that is continuous with the interior side of the recessed wall portion 511a, and a cover mounting portion 511c is provided at the interior side end of the flow-straightening recessed wall portion 511b.

[0016] The outer peripheral cover 512 of the opening-side member 51 is made of a non-metallic material such as rubber or synthetic resin, and has a flat plate-shaped cover body 512a, with a mounting projection 512b provided on the upper interior-side surface of the cover body 512a. Preferably, the outer peripheral cover 512 is made of a material that is flexible enough to be deformed by pinching it with your hands, such as rubber or a soft resin material.

[0017] The opening-side member 51 is formed as a long member with a roughly L-shaped cross-section overall, comprising an upper wall and an outer peripheral cover portion, by engaging the mounting projection 512b of the outer peripheral cover 512 with the cover mounting portion 511c provided on the opening-side main body 511.

[0018] As shown in FIGS. 5(a) and 5(b), the frame side member 52 constituting the ventilation device 5 has a frame side main body 521 arranged along the outer peripheral surface of the upper frame 11, and an inner peripheral side cover (inner peripheral side cover portion) 522 attached to the indoor side end of the frame side main body 521. The frame side main body 521 of the frame side member 52 is made of a metal material such as an aluminum alloy, has a projected dimension similar to that of the frame body 1, and a cover attachment portion 521b is provided at the indoor side end.

[0019] The inner peripheral side cover 522 of the frame side member 52 is made of a non-metallic material such as rubber or synthetic resin, and has a finding wall 522a, a projected wall 522b extending indoors from the lower end (inner peripheral end) of the finding wall 522a, and a guiding wall 522c that connects the upper part of the finding wall 522a and the indoor side part of the projected wall 522b and curves and extends indoors as it goes inward. The inner peripheral side cover 522 is preferably formed of a deformable material such as rubber or a soft resin material for example.

[0020] The inner peripheral side cover 522 has an attachment protrusion 522d provided on the upper outdoor side surface of the finding wall 522a, and for example, a fin-shaped seal protrusion 522e is provided on the lower outdoor side surface of the finding wall 522a. The seal protrusion 522e is preferably formed of a material having flexibility such as rubber or a soft resin material.

[0021] The frame side member 52 is formed as a long member having an upper wall and an inner peripheral side cover portion by engaging the attachment protrusion 522d of the inner peripheral side cover 522 with the cover attachment portion 521b provided on the frame side main body 521.

[0022] The column member 53 constituting the ventilation device 5 is made of a metal material such as an aluminum alloy, and as shown in FIGS. 4(a) and 4(b), FIGS. 5(a) and 5(b), is a rectangular parallelepiped member penetrating vertically, that is, a rectangular parallelepiped member having a substantially rectangular hollow cross-section having an indoor side wall 53a, an outdoor side wall 53b, and left and right side walls 53c, 53c and not having upper and lower walls, and a plurality of screw holes 53e are provided inside the left and right side walls 53c, 53c.

[0023] The ventilation device 5 is formed by arranging a plurality of column members 53 with a longitudinal gap between the opening-side member 51 and the frame-side member 52, with the opening-side member 51 being fastened to the column members 53 from above (outer circumference side) using screw holes 53e, and the frame-side member 52 being fastened to the column members 53 from below (inner circumference side) using screw holes 53e.

[0024] The ventilation device 5, formed by screwing the opening-side member 51 and the frame-side member 52 to the column member 53, has a ventilation passage A between the opening-side member 51 and the frame-side member 52 that communicates with the inside and outside of the building. A rectifier section B is formed on the inside side of the ventilation passage A, having an outer peripheral cover 512 that is provided on the inside side of the opening-side member 51 and extends inward, and an inner peripheral cover 522 that is provided on the frame-side member 52 and extends inward.

[0025] The ventilation device 5, positioned between the building opening and the upper frame 11 of the sliding window frame 1, has an outer peripheral cover 512 provided on the interior side of the opening-side member 51 that covers the interior opening of the ventilation passage A, and an inner peripheral cover 522 provided on the interior side of the frame-side member 52 that extends to the interior side of the upper frame 11, with a sealing projection 522e provided on the exterior lower end of the inner peripheral cover 522 in contact with the interior side surface of the upper frame 11.

[0026] (Operation and effects of the opening device of this embodiment) As described above, in this embodiment, since the ventilation device 5 is provided between the building opening and the frame 1, the room can be ventilated without opening the window. Furthermore, since the ventilation device 5 in this embodiment is provided separately from the frame and sliding door, it is possible to provide an opening device with a ventilation device using existing frames and sliding doors. Furthermore, in this embodiment, since the ventilation device 5 is provided along the longitudinal direction of the frame, the opening area for ventilation can be made larger compared to when the ventilation device is provided on a shoji screen or the like, and the ventilation performance can be improved. Furthermore, since the opening device of this embodiment is provided with a flow straightening section B having a non-metallic member on the indoor side of the ventilation passage A of the ventilation device 5, it has excellent heat insulation properties and can suppress condensation in the ventilation device 5.

[0027] Furthermore, as shown in Figure 5(a), the opening device of this embodiment guides the airflow that has passed through the ventilation passage A downward (inward direction) by the outer peripheral cover (outer peripheral cover portion) 512 of the flow straightening section B provided on the indoor side of the ventilation passage A of the ventilation device 5, and the inner peripheral cover (inner peripheral cover portion) 522 can gently guide the airflow that has been guided downward (inward direction) by the outer peripheral cover (outer peripheral cover portion) 512 towards the indoor side. In particular, the inner circumferential cover (inner circumferential cover portion) 522 of the ventilation device 5 of this embodiment has a guide wall 522c that curves and extends inward towards the room as it goes inward, so that the airflow guided downward (inward direction) can be guided more gently towards the room. Furthermore, the inner perimeter cover (inner perimeter cover section) 522 of the ventilation device 5 has a curved guide wall 522c on the indoor side, which makes it less likely for debris to accumulate near the indoor opening of the rectifier section B that is visible from the indoor side, and also makes it easier to clean the area near the indoor opening.

[0028] Furthermore, in this embodiment, the opening device is positioned such that the outer peripheral cover 512 of the rectifier section B of the ventilation device 5 covers the indoor opening of the ventilation passage A. As shown in Figure 6(a), this allows for a screen to conceal the indoor opening of the ventilation passage A from normal line of sight, thereby improving the aesthetic appeal.

[0029] Furthermore, in this embodiment, the opening device is provided such that the inner circumference cover 522 of the rectifier section B of the ventilation device 5 extends from the frame-side body 521 positioned above the upper frame 11 to the indoor side of the upper frame 11. This allows the gap between the ventilation device 5 and the upper frame 11 to be concealed by the inner circumference cover 522, and the gap with the upper frame 11 is sealed by the sealing projection 522e. This prevents dirt and other debris from entering the gap, improves the aesthetic appearance, and prevents condensation.

[0030] Furthermore, in this embodiment, the opening device has an outer peripheral cover 512 and / or an inner peripheral cover 522 that form the rectifying section B of the ventilation device 5, which are made of a deformable soft material. As shown in Figure 6(b), the outer peripheral cover 512 can be deformed by pinching it with your fingers, or the inner peripheral cover 522 can be deformed, making it easy to clean the ventilation device 5 and the space between the ventilation device 5 and the frame 1. In other words, the ventilation device 5 of the opening can be made more maintainable by forming at least one of the outer peripheral cover 512 and the inner peripheral cover 522 with a deformable resin or the like.

[0031] (modified version) In this embodiment, the ventilation device 5 is provided between the upper frame 11 of the frame 1 and the building opening. However, the position of the ventilation device 5 in the opening is not limited to between the building opening and the upper frame 11 of the frame 1. It may be at any position between the building opening and the frame 1, such as between the building opening and the vertical frames 13 and 14 of the frame 1.

[0032] Furthermore, the material of the opening-side body 511 and the frame-side body 521 that form the ventilation passage A is not limited to a metal material such as an aluminum alloy, but may be made of a resin material, for example, and the outer peripheral cover 512 and the inner peripheral cover 522 may be formed integrally. Furthermore, the material of the column member 53 is not limited to metal materials such as aluminum alloy, but may also be formed from, for example, a block made of resin material or a piece of wood.

[0033] In this embodiment, the ventilation device 5 is formed by screwing the opening-side member 51 and the frame-side member 52 to the screw holes 53e of the column member 53. However, when a block-shaped member is used as the column member 53, the opening-side member 51 and the frame-side member 52 may be attached to the column member 53 with double-sided tape or the like, or they may be formed by directly screwing them to the block-shaped column member 53. Furthermore, when the ventilation device 5 is installed between the building opening and the frame 1, the opening-side member 51, the column member 53, and the frame-side member 52 may be fastened together with long screws or the like to the building opening or the frame 1, and the method of forming the ventilation device 5 is not limited. It goes without saying that the embodiments described above are not intended to limit the inventions described in the claims, but are to be treated as illustrative examples. [Explanation of symbols]
