When attached to the upper frame member 111, the contact piece 115c of the auxiliary frame member 115 protrudes inward from the inner surface of the upper frame member body portion 111a of the upper frame member 111.

[0053] In the upper frame 11 to which the auxiliary frame member 115 is attached, a block-shaped rotation limiting member 117 is positioned between the inner circumferential surface of the upper frame member main body portion 111a of the upper frame member 111 and the contact piece 115c of the auxiliary frame member 115. The indoor side surface of the contact piece 115c of the auxiliary frame member 115 abuts against the outdoor side surface of the rotation limiting member 117, and the upper end of the projection 115d abuts against the outdoor facing wall portion 111d of the upper frame member 111.

[0054] -Third Embodiment- As shown in Figure 7(a), the auxiliary frame material 115 of the opening device in this embodiment has a recessed wall portion 115a, an engaging portion 115b that is continuous with the indoor side end of the recessed wall portion 115a and extends in the indoor direction, a contact piece 115c that extends in the circumferential direction from the indoor side of the recessed wall portion 115a and then bends in the indoor direction, and a projection 115d that extends outward from the recessed wall portion 115a on the outdoor side of the engaging portion 115b, and a trim mounting groove 115e is provided on the inner circumferential surface of the recessed wall portion 115a.

[0055] As shown in Figure 7(b), the auxiliary frame member 115 is attached to the upper frame member 111 by engaging its engaging portion 115b with the mounting groove portion 111c of the upper frame member 111. When attached to the upper frame member 111, the contact piece 115c of the auxiliary frame member 115 protrudes inward from the inner surface of the upper frame member body portion 111a of the upper frame member 111.

[0056] The upper frame 11 to which the auxiliary frame member 115 is attached has a rotation-restricting member 117, such as a bolt, attached from the inner circumferential direction to the indoor side position of the upper frame member body portion 111a of the upper frame member 111, the contact piece 115c of the auxiliary frame member 115 contacting the rotation-restricting member 117, and the upper end of the projection piece 115d of the auxiliary frame member 115 contacting the outdoor side facing wall portion 111d of the upper frame member 111.

[0057] -Fourth Embodiment- As shown in Figure 8(a), the auxiliary frame material 115 of the opening device in this embodiment has a recessed wall portion 115a, a projection 115d extending outward from the outdoor side of the recessed wall portion 115a, an engaging portion 115b extending inward from the indoor side of the projection 115d, and a contact piece 115c extending inward from the indoor side of the recessed wall portion 115a, and a trim mounting groove 115e is provided on the indoor inner surface of the recessed wall portion 115a.

[0058] As shown in Figure 8(b), the auxiliary frame member 115 is attached to the upper frame member 111 by engaging its engaging portion 115b with the mounting groove portion 111c of the upper frame member 111. When attached to the upper frame member 111, the recessed wall portion 115a of the auxiliary frame member 115 is positioned along the inner circumferential surface of the upper frame member body portion 111a of the upper frame member 111.

[0059] In the upper frame 11 to which the auxiliary frame member 115 is attached, a block-shaped rotation limiting member 117 is positioned between the inner circumferential surface of the main body portion 111a of the upper frame member 111 and the contact piece 115c of the auxiliary frame member 115. The indoor side surface of the contact piece 115c of the auxiliary frame member 115 abuts against the outdoor side surface of the rotation limiting member 117, and the upper end of the projection 115d abuts against the upper frame member 111.

[0060] (Effects of the opening device of this embodiment) In this embodiment, the opening device uses the mounting groove 111c for attaching the airtight material to the upper frame material 111 to attach the auxiliary frame material 115. Therefore, there is no need to newly form a structure for attaching the auxiliary frame material 115, and the complexity of the manufacturing process can be prevented.

[0061] In this embodiment, when the engaging portion 115b of the auxiliary frame member 115 is engaged with the mounting groove portion 111c of the upper frame member 111, a rotation limiting member 117 is positioned on the inner circumference side of the engaging portion 115b between the upper frame member body portion 111a of the upper frame member 111 and the contact piece 115c of the auxiliary frame member 115. Since the contact piece 115c of the auxiliary frame member 115 comes into contact with the rotation limiting member 117, the rotation of the auxiliary frame member 115 counterclockwise around the engaging portion 115b is restricted, thereby preventing the auxiliary frame member 115 from coming off or being damaged.

[0062] In this embodiment, when the engaging portion 115b of the auxiliary frame member 115 is engaged with the mounting groove portion 111c of the upper frame member 111, the upper end of the projection 115d of the auxiliary frame member 115 abuts against the upper frame member 111 on the outer circumference side of the engaging portion 115b. This increases the rigidity of the entire upper frame and restricts the clockwise rotation of the auxiliary frame member 115 around the engaging portion 115b, thereby preventing the panel opening from opening and the panel from falling.

[0063] (Mounting structure for auxiliary frame material of the lower frame when a fixed window is configured) The mounting structure of the auxiliary frame member 125 to the lower frame member 121 of the opening device in this embodiment will be described in detail. In this embodiment, the auxiliary frame member 125 of the lower frame 12 is a component that is attached to the lower frame member 121 when the window is used as a fixed window to form a panel opening.

[0064] As shown in Figure 9, the auxiliary frame material 125 of the lower frame 12 of the opening device in this embodiment has a recessed wall portion 125a, a hollow main body portion 125b provided on the inner circumference side of the recessed wall portion 125a, and an opening wall portion 125c that extends outward from the outdoor side surface of the main body portion 125b and then extends inward.

[0065] The auxiliary frame member 125 has a groove-shaped first engaging portion 125d that opens inward and recesses outward (inward direction) along the longitudinal direction at the outdoor end of the recessed wall portion 125a, and a groove-shaped second engaging portion 125e that opens downward and recesses inward (inward direction) along the longitudinal direction at a position spaced apart from the first engaging portion 125d of the recessed wall portion 125a, specifically on the indoor side of the recessed wall portion 125a.

[0066] The lower frame member 121 of the lower frame 12 to which the auxiliary frame member 125 is attached has a first engaging portion 121c along its longitudinal direction that protrudes outward (in depth direction) on the inner circumference side of the lower frame member body 121a, and a second engaging portion 121d along its longitudinal direction that protrudes inward (in width direction) on the indoor inner circumference side of the lower frame member body 121a at a position spaced apart from the first engaging portion 121c in the depth direction, specifically on the indoor inner circumference side of the lower frame member body 121a.

[0067] As shown in Figure 10(a), the auxiliary frame member 125 engages with the first engaged portion 121c of the lower frame member 121 from the outside, and rotates clockwise around the engaged first engaged portion 125d as an axis, thereby engaging with the second engaged portion 125e of the lower frame member 121 from above, and is placed on the inner circumferential surface of the lower frame member 121.

[0068] As shown in Figure 10(b), the auxiliary frame member 125, which is placed on the inner circumferential surface of the lower frame member 121, has its vertical movement (visible direction) suppressed by the engagement of the first engaging portion 125d and the first engaged portion 121c, and its movement in the indoor / outdoor direction (depth direction) is suppressed by the engagement of the second engaging portion 125e and the second engaged portion 121d.

[0069] The auxiliary frame member 125 is placed on the inner circumferential surface of the lower frame member 121 and is attached to the lower frame member 121 by inserting a screw (fixing means) b1 from the inner circumferential side between the first engaging portion 125d which engages with the first engaged portion 121c of the lower frame member 121 and the second engaging portion 125e which engages with the second engaged portion 121d of the lower frame member 121. The panel opening is formed by the opening wall portion 125c of the auxiliary frame member 125 and the opening wall portion 124c of the resin lower member 124.

[0070] (Effects of the opening device of this embodiment) In this embodiment, the opening device is placed on the lower frame member 121 with the auxiliary frame member 135 engaged with an engaging portion that restricts movement in the visible direction and an engaging portion that restricts movement in the depth direction. This ensures that the auxiliary frame member 125 is securely fixed, easy to position, and easy to install.

[0071] In this embodiment, the opening device is such that the auxiliary frame member 125 is engaged with the frame member at two engaging portions that engage in the depth direction and the visibility direction, and is then fixed between these engaging portions by the fixing means b1. Therefore, misalignment is less likely to occur when fixing with the fixing means b1, making construction easier and reducing the number of fixing points.

[0072] (Mounting structure for auxiliary frame material of vertical frame when a fixed window is configured) The mounting structure of the auxiliary frame member 135 to the vertical frame member 131 of the window in this embodiment will be described in detail. In this embodiment, the auxiliary frame member 135 of the vertical frame 13 is a member that is attached to the vertical frame member 131 when the window is used as a fixed window to form a panel opening, and is attached to the vertical frame member 131 using the protruding piece 131c provided on the vertical frame member 131 to seal the gap in close proximity to the vertical frame 23 of the sash.

[0073] As shown in Figure 11(a), the auxiliary frame material 135 of the opening device in this embodiment has a recessed wall portion 135a, an indoor side piece 135b extending outward from the indoor side end of the recessed wall portion 135a, an engaging piece 135c extending outward from an intermediate portion in the depth direction of the recessed wall portion 135a, and a projection piece 135d extending outward from the outdoor side end of the recessed wall portion 135a, and a trim mounting groove 135e is provided on the outdoor side inner circumferential surface of the recessed wall portion 115a. The auxiliary frame material 135 is provided with an engaged portion 135f that is recessed in the outward direction (depth direction) at the portion of the engaging piece 135c that faces the indoor side piece 135b.

[0074] The vertical frame member 131 of the opening device in this embodiment has a recessed wall portion 131a positioned on the inner circumferential surface of the building opening, and a protruding piece 131c that protrudes inward from the outer inner circumferential surface of the recessed wall portion 131a, and an engaging portion 131d that protrudes outward (in the recessed direction) is provided at the inner circumferential end of the protruding piece 131c.

[0075] As shown in Figure 11(b), the auxiliary frame member 135 is positioned on the inner surface of the inner wall portion 131a of the vertical frame member 131, with the protruding piece 131c of the vertical frame member 131 placed between the indoor side piece 135b and the engaging piece 135c, and the engaged portion 135f of the engaging piece 135c of the auxiliary frame member 135 engaged in the inner direction with the engaging portion 131d provided on the inner circumferential end of the protruding piece 131c of the vertical frame member 131.

[0076] The auxiliary frame member 135, positioned on the inner circumferential surface of the recessed wall portion 131a of the vertical frame member 131, is attached to the vertical frame member 131 by inserting a fitting member 137, such as a screw, from the inner circumferential side of the recessed wall portion 135a at a position between the indoor side piece 135b and the engaging piece 135c.

[0077] As shown in Figure 11(c), the vertical frame 13 to which the auxiliary frame member 135 is attached is restricted from moving in the direction toward the outside by the fitting member 137, thereby preventing the disengagement of the engagement state between the engaging portion 131d of the protruding piece 131c of the vertical frame member 131 and the engaged portion 135f provided on the engaging piece 135c of the auxiliary frame member 135. The vertical frame 13 to which the auxiliary frame member 135 is attached has the outer peripheral end of the projection 135d of the auxiliary frame member 135 in contact with the inner peripheral surface of the recessed wall portion 131a of the vertical frame member 131.

[0078] (Effects of the opening device of this embodiment) In this embodiment, the opening device uses a protruding piece 131c of the vertical frame member 131 to provide airtightness in close proximity to the vertical frame 23 of the sliding door, thereby attaching the auxiliary frame member 135. This eliminates the need to process the vertical frame member 131 to attach the auxiliary frame member 135, thus preventing the construction from becoming complicated.

[0079] In this embodiment, the opening device allows the auxiliary frame member 135 to be easily and firmly fixed to the vertical frame member 131 by inserting a fitting member 137, such as a screw, from the inner circumference side of the recessed wall portion 135a of the auxiliary frame member 135. In this embodiment, when the auxiliary frame member 135 is fixed to the vertical frame member 131, the outer peripheral end of the projection 135d of the auxiliary frame member 135 abuts against the vertical frame member 131 on the outdoor side of the engaging portion. This prevents the recessed wall portion 135a of the auxiliary frame member 135 from bending around the engaged portion 135f as an axis, thereby preventing the panel opening from opening and the panel from falling.

[0080] -Other Embodiments- In the opening device, the configuration of the rotation limiting member 117 that restricts the counterclockwise rotation of the auxiliary frame member 115 in the upper frame is not limited to that of the above embodiment. Furthermore, even without the rotation limiting member 117, the contact piece 115c of the auxiliary frame member 115 may directly contact the upper frame member 111 to restrict counterclockwise rotation.

[0081] The configuration of the projection 115d that restricts the clockwise rotation of the auxiliary frame member 115 in the opening device is not limited to that of the above embodiment, and the clockwise rotation may be restricted by contacting the upper frame member 111 via another member such as a rotation restricting member.

[0082] In the opening device, the configuration of the fitting member 137 for fixing the auxiliary frame material 135 in the vertical frame is not limited to that of the above embodiment.

[0083] The opening device may have an engaging portion 131d provided on the protruding piece 131c of the vertical frame member 131 that protrudes towards the interior side, and an engaging portion may be provided on the interior side piece 135b of the auxiliary frame member 135 that engages with the engaging portion 131d of the protruding piece 131c.

[0084] In an opening device, the structures of the upper frame, lower frame, and vertical frame can be applied to other frame structures, provided that no inconsistencies arise. Furthermore, auxiliary frame materials are not limited to those used to form panel openings; their function and purpose are not restricted as long as they are components that are attached to the frame material in an auxiliary manner.

[0085] The opening device is not limited to windows equipped with a frame material that can be used for both vertical sliding windows and fixed windows. For example, any combination of windows is acceptable, such as an opening device equipped with a frame material that can be used for both sliding windows and fixed windows. Furthermore, the structure for attaching auxiliary frame members to the frame member is not limited to windows where the frame member can also be used for other purposes.

[0086] 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]
