Description

This disclosure relates to building fixtures. In the context of building fixtures, Patent Document 1 discloses a power supply device for shoji screens, which is used to energize the lead wires on the electric lock side attached to the shoji screen and the lead wires on the control panel side provided on the door frame side. Patent Document 1 describes that in the power supply device, both the shoji screen side electrode and the frame side electrode are constantly biased in opposing directions and move independently, thereby ensuring reliable contact between the two electrodes and preventing poor contact. Japanese Patent Publication No. 2007-297881 This is a view of the door and window fixtures described in this disclosure, seen from the interior side.This is an enlarged view of the power supply device described herein, as seen from the indoor side.This is a perspective view of the power supply device of this disclosure, as seen from the outside.This is a cross-sectional view of the contacting power supply electrode and power receiving electrode.This is an enlarged view of the power supply device described herein, as seen from the indoor side.This figure shows a modified example of the power supply device of this disclosure.This figure shows a modified example of the power supply device of this disclosure. The embodiments of the building components described herein will be explained below with reference to Figures 1 to 7. The following embodiments represent one aspect of this disclosure and are not limiting; they can be modified at will within the scope of the technical concept of this disclosure. Furthermore, in the following drawings, the scale and other aspects of each structure differ from the actual structure for clarity. The overall structure of the joinery 1 will now be described. As shown in Figure 1, the joinery 1 comprises a rectangular frame 2 attached to an opening 1A formed in the wall of a building, sliding screens 10A and 10B that can slide horizontally within the frame 2, and a power supply device 30. The frame 2 has an upper frame 3, a lower frame 4, and left and right vertical frames 5, and is formed in a rectangular frame shape. In the following, when a door or window 1 is installed in a building opening and viewed from the inside, the vertical direction is referred to as the vertical direction, and the horizontal direction as the horizontal direction. The direction perpendicular to the horizontal direction and aligned with the indoor/outdoor direction is called the depth direction. The depth direction corresponds to the first direction. The vertical direction corresponds to the second direction. The door/window 1 consists of an outer sliding screen 10A and an inner sliding screen 10B, both housed within the frame 2 in the depth direction, for opening and closing the opening 1A. The outer screen 10A is located on the exterior side, and the inner screen 10B on the interior side, allowing the opening 1A to open and close horizontally. Both screens 10A and 10B are sliding screens. Shoji screens 10A and 10B each have an upper frame 11, a lower frame 12, and left and right vertical frames 13 and 14, forming a rectangular frame. The vertical frame 13 in shoji screen 10A corresponds to the door-edge frame located on the door-edge side of shoji screen 10A. In the following description, the vertical frame 13 in shoji screen 10A will be referred to as the door-edge frame 13. For example, glass is housed inside shoji screens 10A and 10B. The power supply device 30 comprises a frame-side device 30A and a sliding door-side device 30B. The frame-side device 30A is installed inside the left vertical frame 5 of the frame body 2. The vertical frame 5 corresponds to the frame body 2. The sliding door-side device 30B is installed inside the door frame 13. The power supply device 30 supplies power from the frame-side device 30A to the sliding door-side device 30B. As shown in Figures 2 and 3, the frame-side device 30A includes a first link mechanism 50A, a power supply side electrode 31A, a first shielding portion 32A, and a first protruding portion 33A. The first link mechanism 50A moves the power supply electrode 31A to the opposite side of the direction of movement of the first protrusion 33A as the first protrusion 33A moves in the opposing direction. The first link mechanism 50A includes a fixed plate 51A, a first guide portion 52A, a guide shaft 53A, a guide shaft 54A, a movable portion 55A, a movable portion 56A, a movable portion 57A, a joint 58A, a joint 59A, a joint 60A, a link 61A, and a link 62A. The fixing plate 51A is a rectangular plate extending vertically and is fixed to the inner surface of the left side of the vertical frame 5. The first guide portion 52A is a rectangular plate extending from the top to the right of the fixing plate 51A in an opposing direction. The right end of the first guide portion 52A is separated from the inner surface of the right side of the vertical frame 5 by a ga
