A rail for a covering for an architectural opening is provided. The rail may be attachable to a shade member of the covering. The rail may include a magnet assembly that is at least partially positioned within a retention channel formed in the rail to releasably secure the rail to a head rail. The magnet assembly may be positionable along a longitudinal axis of the rail and may include a cam lock assembly that releasably secures the magnet assembly within the retention channel of the rail. According to the present disclosure, the head rail and the rail are held in close proximity to each other to inhibit the passage of light between the rail and a head rail.

A cutting machine for window coverings is disclosed, which includes a worktable, a first cutting device, and a caliper. An abutting member and at least one series of extending graduation marks are provided on a table surface of the worktable. The caliper includes at least one internal gauge point and at least one external gauge point. By making the internal gauge point or the external gauge point of the caliper point at a scale value of the series of extending graduation marks which matches a height of a window opening, and by cutting the slats, the resultant slats are adapted to be installed to the window opening. In addition, a distance between a surface of the first cutting device which bears the slats and the table surface of the worktable is short, which makes the stacked slats can be cut in a substantially horizontal way.

A corner bracket for a window blind frame, the corner bracket including a central body portion and extending from the central body portion a first connector and a second connector, wherein the second connector is angled relative to the first connector; each connector includes a locating arm, a friction plate and a stop surface; wherein each friction plate defines a pair of opposed surfaces and each surface carries thereon a respective outwardly projecting deformable rib; and wherein each locating arm further includes at least one further outwardly projecting deformable rib.

In one aspect, a slat configured for use with a covering for an architectural structure includes a route slot defined at least partially by a route wall that is recessed relative to one or more outer faces of the slat. Additionally, the recessed route wall further defines a through-hole for passing a cord through the route slot between the opposed outer faces of the slat. By configuring the disclosed route slot in this manner, the dimensions of the through-hole can be significantly reduced while still allowing full tilting of the slat to the closed position, thereby increasing light control and privacy for the associated covering.

A mounting bracket lock may be configured to secure the mounting bracket of a window treatment housing to a rail of the housing. The mounting bracket lock may be slidably attachable to the rail and, when in a locked position, may prevent the mounting bracket from detaching from the rail. The mounting bracket lock may include a body that is mountable to the rail. The body may include a first portion that slidably attaches to the rail, and a second portion that receives a portion of the rail and a portion of the mounting bracket, thereby securing the mounting bracket in a locked position relative to the rail. The body of the mounting bracket lock may define one or more projections that extend therefrom, and that engage in a friction fit between corresponding surfaces of the mounting bracket when the mounting bracket lock is in the locked position.

A method for installing sunshade in light opening of building element is disclosed. The light opening comprises first and second edge surfaces. A glazing unit extends from the first edge surface to the second edge surface. The first and/or second edge surface is provided with at least two fastening holes. A fastener is installed in the fastening holes. Installation rail is attached to the fasteners which comprise a tip and a head part. Before the building element is mounted in the building, fastening holes are provided and the first ends of the fastening holes opening in the first and/or the second edge surface are closed. The first ends of fastening holes are opened in connection with installing fasteners. Fasteners are driven in fastening holes by inserting or screwing the tip part into the fastening hole, and the installation rails are attached to the head part remaining outside the fastening hole.
