JP-2026075893-A - Attachments and joinery

Abstract

[Problem] To provide an attachment and joinery that allows for easy attachment of various external layers and reduces the risk of processing errors and damage to the joinery frame. [Solution] The attachment 3 comprises a four-sided frame attachment 30 to which an external shade 7, which is an external layer, is attached, and a locking member 42 for locking the four-sided frame attachment 30 to the door frame 10. The four-sided frame attachment 30 is constructed by framing an upper member 31, a lower member 32, and left and right vertical members. The upper member 31 is a first frame member that is mechanically fixed to the door frame 10, and the lower member 32 and vertical members are second frame members that are locked to the door frame 10 by the locking member 42. The second frame member has a lockable portion that is locked to the locking member 42. The locking member 42 comprises a fixing portion that is mechanically fixed to the door frame 10, and a locking portion that locks the lockable portion of the second frame member so that it is movable in the longitudinal direction and the visible direction of the second frame member with respect to the locking member, but not movable in the depth direction of the door frame.

7. In the joinery described in claim 5, The aforementioned door frame is a resin frame made of synthetic resin, A joinery piece characterized in that the upper member, lower member, and left and right vertical members of the four-sided frame attachment, and the locking member, are made of metal.

Description

This invention relates to an attachment used for attaching exterior layers (window components) such as shades, louvers, and grilles to the exterior side of a door frame, and to a door equipped with the same. 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. Japanese Patent Publication No. 2017-197954 This is a vertical cross-sectional view showing the joinery of the first embodiment.This is a cross-sectional view showing the joinery of the first embodiment.This is a schematic diagram showing the attachment of the first embodiment.This is a perspective view showing the attachment of a four-sided frame attachment to a door frame.(A) is a longitudinal cross-sectional view showing the upper member of the four-sided frame attachment, and (B) is a longitudinal cross-sectional view showing the lower member.(A) is a cross-sectional view showing one of the vertical members of the four-sided frame attachment, and (B) is a cross-sectional view showing the other vertical member.This is a perspective view showing the four-sided frame attachment being attached to the door frame with a locking member.(A) is a cross-sectional view showing the vertical members and locking members of the four-sided frame attachment, and (B) is a longitudinal cross-sectional view showing the lower members and locking members.This is a perspective view showing the external shade being attached to the four-sided frame attachment.This is a perspective view showing the exterior shade attached to the four-sided frame attachment.This is a vertical cross-sectional view showing the joinery of the second embodiment.This is a cross-sectional view showing the joinery of the second embodiment. [First Embodiment] The following describes the joinery 1 of the first embodiment of the present invention based on 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 exterior shade 7, which is an exterior layer, is attached to the exterior side of the door 1 via an attachment 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 that have been 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 include 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 of the window frame body 15. As shown in Figures 5 and 6, the drain section 16 is hollow in shape and comprises an outer peripheral surface section 161 and an inner peripheral surface section 162 extending outward from the outer peripheral surface section 151 that constitutes the outdoor surface of the window frame body 15, and an outdoor peripheral surface section 163 that connects the outdoor ends of the outer peripheral surface section 161 and the inner peripheral surface section 162. The inner peripheral surface section 162 is inclined to approach the outer peripheral surface section 161 as it moves from the outer peripheral surface section 151 towards the outer peripheral surface section 163. 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. Th
