[Solution] The connecting device is used to attach an outer layer to the frame material of a door or window. The connecting device comprises a backing plate member 30 and a connecting component 40. The backing plate member 30 comprises two backing plates 31. Each backing plate 31 comprises an insertion piece that is inserted through an insertion hole 152 formed in the exterior surface portion 151 of the hollow portion of the frame material and positioned within the hollow portion, and an extension piece 315 that extends outward from the insertion hole 152. The connecting component 40 comprises a fixing portion 41 that is fixed to the insertion piece through a through hole 153 formed in the exterior surface portion 151, a connecting portion 43 into which the outer layer is connected, and an engagement hole 411 into which the extension piece 315 engages.

A method for attaching a connecting device, characterized by attaching a fastening member to the fixing hole of the insertion piece through the through holes of the fixing portion and the exterior surface portion, thereby attaching the connecting device to the frame material.

Description

This invention relates to a connecting device used for attaching external layers (window components) such as shades, louvers, and grilles to a building fixture, a building fixture equipped with the connecting device, and a method for attaching the connecting device. When attaching exterior layers such as shades to the exterior side of a synthetic resin window frame, conventional methods involved using screws or other fasteners to attach them to the surrounding wall. However, this required drilling screw holes in the exterior wall, necessitating waterproofing treatments and making on-site work complicated. Therefore, Patent Document 1 discloses a structure in which a device to be mounted, such as a screen device, is directly attached to a resin frame by using a mounting device that includes a bracket and a retaining fitting on the resin frame. In Patent Document 1, a mounting hole is formed in the resin frame, a turn nut is fitted into this mounting hole, and the bracket is attached by a screw that is screwed into the turn nut.

[First Embodiment] The building fixture 1 of the first embodiment of the present invention will be described below with reference to the drawings. As shown in Figures 1 and 2, the joinery 1 of the first embodiment comprises a joinery frame 10 that is attached to the wall of a building, and a sliding screen 20 that opens and closes relative to the joinery frame 10. The joinery 1 of this embodiment is an inward-opening window in which the sliding screen 20 can be opened and closed relative to the joinery frame 10 in two ways: inward opening and inward tilting. In this embodiment, an external shade 7, which is an external layer, is attached to the exterior side of the door 1 via a connecting device 3. In the following explanation, the interior-exterior direction of door/window 1 is defined as the depth direction, and the direction perpendicular to both the depth direction and the vertical direction of door/window 1 is defined as the left-right direction. Also, in order to improve the clarity of the drawings, hatching indicating cross-sections will be omitted in each figure. The window frame 10 is constructed by joining an upper frame 11, a lower frame 12, and left and right vertical frames 13 and 14 in a rectangular shape. As shown in Figures 1 and 2, the upper frame 11, lower frame 12, and vertical frames 13 and 14 are made of synthetic resin material with the same cross-sectional shape, and are framed by welding together the ends of each frame cut at a 45° angle to the longitudinal direction. In this embodiment, the upper frame 11, lower frame 12, and vertical frames 13 and 14 comprise a window frame body 15, which is the main body of the window frame, and a drip edge 16 that protrudes outward from the exterior surface 151 of the window frame body 15. Furthermore, as shown in Figure 2, the window frame body 15 includes a hollow section 17 located on the interior side of the drip edge 16, into which the backing plate member 30 of the connecting device 3 is inserted. The shoji screen 20 is constructed by joining an upper frame 21, a lower frame 22, and left and right vertical frames 23 and 24 in a rectangular shape. The glass 25, positioned on the inner circumference, is held in place by the upper frame 21, lower frame 22, vertical frames 23 and 24,
