DETAILED DESCRIPTION OF THE INVENTION

[0009] The opening device of this embodiment is a vertical sliding window in which a shoji screen 2 is formed by fitting a panel body 25 such as double-glazed glass onto the inner periphery of a frame body fixed to an opening in a building, the panel body 25 being made up of an upper frame 21, a lower frame 22, a hanging frame 23, and a door end frame 24, as shown in Figure 1, and is arranged so that it can slide out vertically. The opening device of this embodiment will be described below, but the explanation of the configuration of the frame materials and stile materials of the opening device will mainly be done using the upper frame 11 and upper stile 21, and explanations of the other frame materials and stile materials will be omitted.

[0010] The upper frame (frame material) 11 of the frame body of the opening device of this embodiment has a metal upper frame (metal frame) 111 made of a metal material such as an aluminum alloy, and a resin upper frame (resin frame) 112 arranged on the indoor side inner surface of the metal upper frame 111, as shown in Figure 2.

[0011] As shown in Figures 1 to 3, the frame of the shoji screen 2 of the opening device of this embodiment is assembled by abutting the end faces of the metal frame materials of the upper and lower horizontal frames (in Figures 2 and 3, the metal upper frame 211 of the upper frame 21) against the inner surfaces of the metal frame materials of the left and right vertical frames (in Figure 3, the metal vertical frame 241 of the door end frame 24), and fixing them from the outer periphery of the left and right vertical frames with screws (fixing means) b1.

[0012] The upper frame 21 of the shoji screen 2 has a metal upper frame 211 made of a metal material such as aluminum and a resin ledge 212. The ledge 212 is attached to the indoor side of the metal upper frame 211 to form a panel opening 21a, and a panel body 25 such as double-glazed glass is fitted into the panel opening 21a via a glazing channel 9.

[0013] The metal upper frame 211 has a concealed wall 211a that forms the bottom wall 21b of the panel opening 21a, and an outdoor concealed wall 211b that is continuous with the outdoor side of the concealed wall 211a, and tapping holes 211c, 211d into which screws b1 are screwed are provided on the indoor and outdoor sides of the concealed wall 211a.

[0014] The shoji screen 2 of the opening device of this embodiment is provided with a spacing retaining part 5 near the door-front end of the upper frame 21 (area A in Figure 1), which maintains a predetermined distance between the bottom wall 21b of the panel opening 21a of the upper frame 21 and the outer peripheral surface of the panel body 25, thereby maintaining the positional relationship between the frame body and the panel body and preventing deformation of the shoji screen. The spacing component 5 will be described in detail below.

[0015] - Spacing parts - The spacing component 5 of this embodiment has a base 51, a screw 52, ​​and a plate component 53, as shown in FIG. 5(d).

[0016] As shown in Figures 4(b) to (e), the base 51 is a block-shaped part made of a resin material that is rectangular in plan view, and has a base main body portion 511 in the central region in plan view that receives the screw head 52a of the screw 52, ​​and has an outer wall portion 512 that surrounds the base main body portion 511 on all four sides.

[0017] The base main body 511 of the base 51 has multiple (in this embodiment, four) flat surfaces of different heights arranged in order of height on its upper surface, and has multiple screw head receiving portions 511a, 511b, 511c, and 511d of different heights (thicknesses).

[0018] The base 51 is provided with a through-hole 511e that penetrates the base main body 511. The through-hole 511e is formed as an elongated hole that continues across the multiple screw head receiving portions 511a, 511b, 511c, and 511d of the base main body 511, and has a width dimension that is sufficient to allow the screw shaft 52b of the screw 52 to pass through.

[0019] The screw 52 is made of a metal material, and as shown in FIG. 4(a), a general screw having a screw head 52a, a screw shaft 52b, and a flat screw tip can be used.

[0020] As shown in Figures 5(a) to (c), the plate component 53 is a component made of a resin material and has a rectangular plate shape in a plan view, and has a thick screw receiving portion 53a that rises along one side in a plan view, a mounting arm portion 53b that rises from one side along the other side, and a curved support portion 53c that curves and extends from the other side of the mounting arm portion 53b to the other side.

[0021] - Maintaining the gap between the frame and the panel body using gap retaining parts - As shown in Figures 2, 3 and 6(a), the upper frame 21 of the opening device of this embodiment has a screw hole 211e provided in the projected wall 211a that forms the bottom wall 21b of the panel opening 21a in area A near the door-front end of the metal upper frame 211, and at the position where the screw hole 211e is provided, the plate part 53 of the spacing part 5 is attached to the inner side of the panel opening 21a so as to overlap with the screw hole 211e.

[0022] The plate part 53 is attached to the inner surface of the panel opening 21a by inserting the mounting arm 53b from the end of the upper frame 21 into the tapping hole 211d on the outdoor side and sliding it to a position overlapping with the screw hole 211e of the upper frame 21.

[0023] The plate part 53 attached to the inner peripheral surface of the panel opening 21a has a curved support portion 53c extending on the other side of the mounting arm portion 53b that elastically abuts against the indoor side of the outdoor facing wall 211b of the upper frame 21, restricting the thick screw receiving portion 53a from rotating downward around the mounting arm portion 53b.

[0024] The upper frame 21 to which the plate part 53 is attached has a tapping hole 211d crimped (211f) on the hanging side of the plate part 53 to restrict movement of the plate part 53 toward the hanging side, and movement of the plate part 53 toward the door end side is restricted by a screw b1 that secures the upper frame 21 and the door end frame 24 screwed into the tapping hole 211d.

[0025] As shown in Figures 2 and 3, the base 51 is positioned with the bottom surface of the base 51 abutting against the outer periphery of the projected wall 211a of the upper frame 21, with the screw hole 211e provided in the projected wall 211a of the upper frame 21 overlapping with the through portion 511e provided in the base main body 511.

[0026] As shown in Figures 2, 5(d), and 6, the screw shaft 52b of the screw 52 penetrates from the outer periphery of the projecting wall 211a of the upper frame 21 into the through-hole 511e of the base 51, and is screwed into the screw hole 211e provided in the projecting wall 211a of the upper frame 21 across the base main body 511. When the screw 52 threaded into the screw hole 211e of the projecting wall 211a is screwed in (threaded), the screw shaft 52b protrudes inside the panel opening 21a and is pressed against the outer peripheral surface of the panel body 25 via the plate part 53, thereby maintaining the distance between the bottom wall 21b of the panel opening 21a and the outer peripheral surface of the panel body 25 at a distance not less than a predetermined distance.

[0027] Before screwing the screw 52 into the screw hole 211e of the upper frame 21 and pressing it against the outer surface of the panel body 25, as shown in Figure 6(b), by moving the base 51 in the direction of arrow X along the longitudinal direction of the through portion 511e, the screw head 52a of the screw 52 is positioned above one of the multiple screw head receiving portions 511a, 511b, 511c, and 511d, and by screwing it in that state, the amount of protrusion of the screw shaft 52b toward the panel opening 21a can be adjusted.

[0028] -Effects of the opening device of this embodiment- In the opening device of this embodiment, spacing retaining parts that maintain the distance between the frame material and the panel body are placed on the frame material that makes up the shoji screen, thereby suppressing deformation of the frame material that is assembled around all four sides and maintaining the correct shape of the shoji screen.

[0029] The opening device of this embodiment is easy to install and maintain, as the spacing between the inner surface of the frame and the outer surface of the panel body can be adjusted by a simple operation from the outer side of the frame, namely, moving the base and screwing in a screw, using the spacing retaining parts.

[0030] In the opening device of this embodiment, a resin plate part that receives the tip of the screw is provided between the screw of the spacing part and the outer surface of the panel body, thereby preventing damage to the panel body due to the screw and the generation of creaking noises. Furthermore, the plate components of the spacing retaining components are held without rattle on the inner peripheral surface of the frame material, and do not interfere with installation when fitting the panel body.

[0031] The spacing parts provided on the frame members may be provided at any location on any frame member, and the number of such parts is not limited. In addition, the base of the spacing retaining part may have multiple screw head receiving portions arranged in a direction perpendicular to the longitudinal direction of the frame material, and the through-holes do not have to be arranged so as to be continuous with the multiple screw head receiving portions, and each screw head receiving portion may have an independent through-hole formed therein. Furthermore, in the base 51, the lower portions of the plurality of flat surfaces of the base main body 511 may be appropriately provided with lightening holes 51a or the like as shown in FIG. 6(b).

[0032] The spacing retaining part does not necessarily have to include a plate part, and may be configured so that the screw abuts against the outer surface of the panel body directly or via other cushioning material, etc., to maintain the gap between the frame material and the panel body. It goes without saying that the above embodiments do not limit the invention described in the claims, but are treated as examples. [Explanation of symbols]
