[Figure 3] This is a cross-sectional view of an opening device according to one embodiment. [Figure 4] This is a cross-sectional view illustrating the assembly of an opening device in one embodiment. [Modes for carrying out the invention]

[0009] As an example of an opening device in an embodiment, we will explain using an example of a fixed window installed on the inner circumference of an opening in a building (hereinafter simply referred to as "opening") with reference to the drawings. As shown in Figure 1, the fixed window of this embodiment is equipped with a panel 15 such as double-glazed glass on the inner circumference of a frame body formed by assembling an upper frame 11, a lower frame 12, and left and right vertical frames 13, 13 around all four sides.

[0010] The upper frame 11 that constitutes the frame body is made of a metal material such as an aluminum alloy, and as shown in Figure 2, it comprises a metal upper frame 111 fixed to the opening, a resin upper frame (resin frame material) 112 fixed to the indoor inner circumference of the metal upper frame (metal frame material) 111, and a resin trim 113.

[0011] The metal upper frame 111 that constitutes the upper frame 11 has a main body portion 111a that has a hollow portion on its outer periphery on the outdoor side and is positioned on the inner circumferential surface of the opening, a visible wall portion 111b that is continuous with the indoor side end of the main body portion 111a, and a panel opening wall portion 111c that extends in the inner circumferential direction (downward) from the outdoor side of the main body portion 111a.

[0012] The metal upper frame 111 has an engaging wall portion 111d extending in the circumferential direction from the inner circumferential surface on the indoor side of the main body portion 111a, and protruding pieces 111h and 111i are provided on the indoor and outdoor sides of the engaging wall portion 111d, respectively, projecting inwards and outwards.

[0013] The metal upper frame 111 has an engaging piece 111g provided at the inner circumferential end of the visible wall portion 111b, which is bent outwards. The indoor side protruding piece 111h of the engaging wall portion 111d and the engaging piece 111g form a resin frame material engaging portion 111e on the indoor side inner circumferential surface.

[0014] The metal upper frame 111 is provided with an engaging piece 111j that protrudes inward in the direction toward the outside of the engaging wall portion 111d, and the protruding piece 111i on the outside of the engaging wall portion 111d and the engaging piece 111j form a trim engaging portion 111f on the inner surface toward the outside of the resin frame material engaging portion 111e.

[0015] The resin upper frame 112 that constitutes the upper frame 11 has a main body portion 112a with an angle portion continuous on the indoor side, and an engaging portion 112b consisting of a pair of engaging pieces 112c and 112d that extend outward from the outer circumference side of the main body portion 112a.

[0016] The resin upper frame 112 is attached to the indoor side inner circumference of the metal upper frame 111 by engaging its engaging portion 112b with the resin frame material engaging portion 111e of the metal upper frame 111.

[0017] The trim piece 113 that constitutes the upper frame 11 has a main body portion 113a having a hollow section, and an engaging portion 113b consisting of a pair of engaging pieces 113c and 113d that extend outward from the outer circumference side of the main body portion 113a.

[0018] The trim piece 113 is attached to the inner circumference of the metal upper frame 111 by having the outer circumference of the main body portion 113a on the indoor side abut against the inner circumference of the main body portion 112a of the resin upper frame 112, and engaging the trim piece engaging portion 112b with the trim piece engaging portion 111f of the metal upper frame 111.

[0019] The upper frame 11 has a panel opening 11a formed by the panel opening wall portion 111c of the metal upper frame 111 and the trim 113. The panel 15 is fitted into the upper frame 11, which has the pre-applied bead, the outdoor side sealant s12, attached to it, and after the trim 113 is inserted, the indoor side sealant s11, which is a post-applied bead, is pushed between the panel body 15 and the trim 113 to hold the upper end of the panel 15.

[0020] The lower frame 12 that constitutes the frame body is made of a metal material such as an aluminum alloy. As shown in FIG. 2, it includes a metal lower frame (metal frame member) 121 fixed to the opening, a resin lower frame (resin frame member) 122 fixed to the inner circumference on the indoor side of the metal lower frame 121, and a resin pressing edge 123. Since the lower frame 12 has the same configuration as the upper frame 11, here, the configuration different from that of the upper frame 11 will be described, and the description of the same configuration will be partially omitted.

[0021] The metal lower frame 121 that constitutes the lower frame 12 has a main body portion 121a that has a hollow portion on the outer circumference of the outdoor side and is disposed on the inner circumferential surface of the opening, a finding wall portion 121b continuous with the indoor side end of the main body portion 121a, and a panel intermediate opening wall portion 121c that extends from the outdoor side of the main body portion 121a in the inner circumferential direction (downward).

[0022] The lower frame 12 forms a panel intermediate opening 12a by the panel intermediate opening wall portion 121c of the metal lower frame 121 and the pressing edge 123, and a setting block 125 is disposed in the panel intermediate opening 12a. The panel 15 is fitted into the lower frame 12 to which the outdoor sealing material s22, which is a pre-attached bead, is attached and placed on the setting block 125. After the pressing edge 123 is inserted, the indoor sealing material s21, which is a post-attached bead, is pushed between the panel body 15 and the pressing edge 123 to hold the lower edge of the panel 15.

[0023] The left and right vertical frames 13 that constitute the frame body are made of a metal material such as an aluminum alloy. As shown in FIG. 3, they include a metal vertical frame (metal frame member) 131 fixed to the opening, a resin vertical frame (resin frame member) 132 fixed to the inner circumference on the indoor side of the metal vertical frame 131, and a resin pressing edge 133. Since the vertical frames 13 have the same configuration on the left and right, here, the left vertical frame 13 will be used for explanation.

[0024] The metal vertical frame 131 that constitutes the vertical frame 13 has a main body portion 131a positioned on the inner circumferential surface of the opening, a visible wall portion 131b that is continuous with the indoor end of the main body portion 131a, and a panel opening wall portion 131c that extends in the circumferential direction from the outdoor side of the main body portion 131a.

[0025] The metal vertical frame 131 has an engaging wall portion 131d extending in the circumferential direction from the inner surface on the indoor side of the main body portion 131a, and protruding pieces 131h and 131i are provided on the indoor and outdoor sides of the engaging wall portion 131d, respectively, projecting inwards and outwards.

[0026] The metal vertical frame 131 has an engaging piece 131g provided at the inner circumferential end of the visible wall portion 131b, which is bent outwards. The indoor side of the engaging wall portion 131d has a protruding piece 131h and the engaging piece 131g forming a resin frame material engaging portion 131e on the indoor side of the inner circumferential surface.

[0027] The metal vertical frame 131 is provided with an engaging piece 131j that protrudes inward in the outdoor direction on the outdoor side of the engaging wall portion 131d. The protruding piece 131i on the outdoor side of the engaging wall portion 131d and the engaging piece 131j form a trim engaging portion 131f on the inner surface that is more outdoors than the resin frame material engaging portion 131e.

[0028] The resin vertical frame 132 that constitutes the vertical frame 13 has a main body portion 132a having a hollow portion, the inner circumferential wall of the hollow portion extending towards the indoor side to form an angle portion, and an engaging portion 132b consisting of a pair of engaging pieces 132c and 132d extending outward from the outer circumferential side of the main body portion 132a.

[0029] The resin vertical frame 132 is attached to the indoor inner circumference of the metal vertical frame 131 by engaging its engaging portion 132b with the resin frame material engaging portion 131e of the metal vertical frame 131.

[0030] The trim piece 133 that constitutes the vertical frame 13 has a main body portion 133a having a hollow section, and an engaging portion 133b consisting of a pair of engaging pieces 133c and 133d that extend outward from the outer circumference of the main body portion 133a.

[0031] The trim strip 133 is attached to the inner circumference of the metal vertical frame 131 on the outdoor side of the resin vertical frame 132 by engaging its engaging portion 132b with the trim strip engaging portion 131f of the metal vertical frame 131.

[0032] The vertical frame 13 forms the panel opening 13a with the panel opening wall portion 131c of the metal vertical frame 131 and the trim 133. The panel 15 is fitted into the vertical frame 13 to which the exterior sealing material s32, which is a pre-applied bead, is attached. After the trim 133 is inserted, the interior sealing material s31, which is a post-applied bead, is pressed between the panel body 15 and the trim 133 to hold the left and right edges of the panel 15. Furthermore, a retractable glass base plate 6 may be placed within the panel opening 13a of the vertical frame 13, if necessary.

[0033] Furthermore, the bead used as a sealing material may be formed by creating a continuous long bead for each bead attached to the upper frame, lower frame, and vertical frame, and then pressed and attached around all four sides after the trim of each frame member is inserted, or it may be formed by creating multiple beads and then pressed and attached to each frame member. Similarly, the pre-attached beads may also be formed by creating a continuous long bead, or by creating multiple beads.

[0034] The fixed window of this embodiment described above is intended to be positioned within the frame by horizontal sliding joints. The panel 15 is fitted into the frame, which has the resin frame material attached to the inner circumference of each metal frame material, by horizontal sliding joints, and then the trim pieces are attached to form the fixed window. Furthermore, if a retractable glass base plate 6 is placed within the panel opening 13a, the glass base plate 6 is stored on the indoor side of the metal vertical frame 131 during horizontal sliding, and after the panel 15 is fitted, the glass base plate 6 is projected into the panel opening 13a, thereby enabling horizontal sliding.

[0035] For the panel 15 to be fitted in by sliding it horizontally, in this embodiment, the resin upper frame 112 of the upper frame 11 and the resin lower frame 122 of the lower frame 12 are positioned with a gap greater than or equal to the height dimension of the panel 15. After the panel 15 is inserted into the frame, the trim pieces 113 and 123 are attached so as to protrude from the inner circumference of the resin upper frame 112 and the resin lower frame 122 to hold the panel 15 in place.

[0036] On the other hand, in the fixed window of this embodiment, the left and right vertical frames 13, 13 are arranged with a gap slightly smaller than the width dimension of the panel 15, and after the panel 15 is inserted into the frame by horizontal sliding, the trim pieces 133, 133 are installed to be inserted between the panel 15 and the resin vertical frame 132 to support the panel 15.

[0037] The trim strip 133, which is inserted and attached between the panel 15 and the resin vertical frame 132, holds the panel 15 on the outdoor side of the main body portion 133a, and the indoor side of the main body portion 133a is supported by the outdoor side of the main body portion 132a of the resin vertical frame 132 in an area extending in the inward and outward directions.

[0038] In this embodiment, the state in which the indoor side of the trim 133 is supported by the resin vertical frame 132 means that the resin vertical frame 132 prevents the trim 133 from coming loose, coming loose, or being damaged due to external forces by contacting the indoor side of the trim 133.

[0039] For example, when the trim strip 133 is inserted and installed, the indoor side of the trim strip 133 will naturally come into contact with the outdoor side of the resin vertical frame 132. In addition, when the trim strip 133 is installed and a post-installation bead is pressed in, the indoor side of the trim strip 133 will come into contact with the outdoor side of the resin vertical frame 132. Furthermore, when the panel 25 is subjected to positive pressure due to wind or the like during use, the indoor side of the trim strip 133 will come into contact with the outdoor side of the resin vertical frame 132.

[0040] Furthermore, in this embodiment, when the fixed window is installed by inserting the trim piece 133 into the outdoor side of the main body of the resin vertical frame 132, a guide portion 132e is provided to guide the indoor-side engaging piece 133c of the trim piece 133 to the trim piece engaging portion 131f of the metal vertical frame 131.

[0041] As shown in Figure 4(a), the guide portion 132e of the resin vertical frame 132 has a curved surface that extends outward from the outdoor side of the main body portion 132a, forming a curved surface toward the outer circumference, and the tip of the curved surface of the guide portion 132e is close to the inner circumference end of the engagement wall portion 131d that forms the retaining edge engagement portion 131f of the metal vertical frame 131.

[0042] The trim piece 133 of the vertical frame 13 is inserted straight from the inner circumference between the panel 15 of the vertical frame 13 on which the panel 15 is placed and the resin vertical frame 132. As a result, a pair of engaging pieces 133c and 133d of the trim piece 133 are pressed straight into the trim engaging portion 131f of the metal vertical frame 131, and are elastically deformed to engage. However, there is some clearance between the panel 15 and the resin vertical frame 132 to push in the sealant s31 that is added later, and as shown in Figure 4(b), the retaining trim 133 may not be inserted straight, and the engaging piece (engaging part) 132c of the retaining trim 133 may get stuck on the indoor side of the engaging wall portion 131d of the metal vertical frame 131, preventing proper engagement.

[0043] In contrast, in this embodiment of the FIX window, because a guide portion 132e is formed on the resin vertical frame 132, even if the retaining trim 133 is not inserted straight between the panel 15 of the vertical frame 13 on which the panel 15 is arranged and the resin vertical frame 132, the tip of the engaging piece 133c of the retaining trim 133 abuts against the curved surface of the guide portion 132e of the resin vertical frame 132, and as the retaining trim 133 is inserted, the engaging piece 133c of the retaining trim 133 is guided along the curved surface to the outdoor side of the retaining trim engaging portion 131f of the metal vertical frame 131, so that the engaging portion 133b of the retaining trim 133 is securely engaged with the engaging portion 131f of the metal vertical frame 131.

[0044] (Effects of the opening device of this embodiment) In this embodiment, the opening device is installed by inserting a resin trim piece that holds the panel between the panel and the resin frame material, and the trim piece 133 is positioned on the outdoor side of the resin vertical frame 132. As a result, the vertical frame 13 is neat and aesthetically pleasing, and the indoor side of the trim piece 133 is supported by the resin vertical frame 132 in an area extending in the inward and outward directions. This allows the trim piece and the resin frame material to withstand external pressure on the panel 15 due to wind, etc., thereby improving the mounting strength of the trim piece and the support strength of the panel.

[0045] In this embodiment, the opening device can improve thermal insulation by attaching a resin frame material to the inner surface of the metal frame material on the indoor side of the trim. Furthermore, the opening device of this embodiment is provided with a guide portion that contacts the engaging portion of the trim when inserting the trim into the outdoor side surface of the resin frame material and guides it to the trim engaging portion of the metal frame material. Therefore, even when the engaging portion for attaching the trim between the panel and the resin frame material is difficult to see, the engaging piece (engaging portion) 132c of the trim 133 will not get stuck on the indoor side of the engaging wall portion 131d of the metal vertical frame 131, making it easier to attach it in the correct form and improving workability.

[0046] The opening device of this embodiment employs a post-installation bead as a sealing material between the trim and the panel, enabling smooth installation even when a resin frame material exists on the opposite side of the panel and the trim is inserted and installed between the panel and the resin frame material.

[0047] -Other Embodiments- In this embodiment, the fixed window has a trim piece inserted into the outdoor side of the vertical resin frame material, and a guide portion is provided in the resin frame material. However, depending on the intended sliding mechanism, the configuration of the vertical and horizontal frames may be reversed, and the resin frame material on which the guide portion is provided is not limited to the vertical frame; the guide portion may also be provided in the upper and lower frames.

[0048] In this embodiment, the fixed window is formed such that the inner surface of the trim of the vertical frame and the inner surface of the resin vertical frame are substantially flush when the trim of the vertical frame is attached to the metal vertical frame. However, the inner surface of the trim of the vertical frame may be formed to be located either further inward or further outward than the inner surface of the resin vertical frame.

[0049] The fixed window of this embodiment has a flat portion on the outdoor side of the resin vertical frame, and the indoor side of the trim is supported by the entire or a part of the outdoor side of the resin frame material in the inward and outward direction region. However, the inward and outward direction region does not have to be a surface region. For example, a plurality of ribs extending in the inward and outward direction may be provided on the outdoor side of the resin vertical frame, and the indoor side of the trim may be supported in the inward and outward direction region of the plurality of ribs.

[0050] In this embodiment, the fixed window has a sealing material for holding the panel formed by pre-applied beads and post-applied beads. However, the thickness of the pre-applied beads and post-applied beads can be adjusted by forming a release layer on the contact surface of the pre-applied beads and post-applied beads with the panel, thereby making it possible to accommodate panels of different thicknesses. Furthermore, the sealing material is not limited to pre-applied beads or post-applied beads.

[0051] The opening mechanism is not limited to fixed windows; a configuration consisting of a metal frame, a resin frame, and a trim can also be used as the frame material for a sliding door. 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]
