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.

The present disclosure relates generally to acoustic panels, for example, suitable for acoustic ceiling surfaces. The present disclosure relates more particularly to acoustic panels that include a panel body (e.g., comprising fiberglass, or having an NRC value in the range of at least 0.5, e.g., 0.5-0.95 or 0.5-0.9) and a perimeter frame extending around a side edge of the panel body. The perimeter frame includes a plurality of frame members including a first frame member and a second frame member. A first adhesive bonds the frame members to the panel body. A second adhesive with a shorter working time may also bond the frame members to the panel body. In addition, or alternatively, a bracket that couples the frame members to one another includes a sharp projection that hinders removal of the bracket from the frame members once assembled. These aspects allow the acoustic panel to be handled before the first adhesive is cured.

Joint for the angular connection of a pair of hollow profile members (50) having an angular configuration corresponding to the angle of the assembled profile members (50) and comprising a slide base portion (2, 2, 2), a sheet metal portion (1, 1) superimposed thereupon and a bolt (5) passing through the sheet metal portion (1, 1) and screwed into a nut (4) mounted onto the base portion (2, 2, 2), wherein tightening of bolt (5) pushes upwardly extending surfaces on either side of portion (1, 1) whereby their sharp edges indent the walls of the hollow profile members being connected. The indentation and efficient angular connection of the hollow profile members is enhanced through: a) forming of the sharp edges of the sheet metal to align an aberrant edge thereof in an indentation appropriate direction, b) appropriately orienting the sheet metal portion (1, 1) to comply with a set of predetermined geometrical parameters and c) selectively employing varying embodiments of the slide base portion to obtain rapprochement of the points of indentation of the walls being indented.

A mitre joint for a metallic frame of a fenestration unit includes first and second frame members; a connector configured to locate the first and second frame members in relation to one another; and first and second fasteners configured to secure the first and second frame members to the connector. The connector has a first arm configured to extend within a hollow profile defined by the first frame member, and a second arm configured to extend within a hollow profile defined by the second frame member. A longitudinal axis of each of the first and second fasteners is configured to be parallel to a longitudinal axis of the respective connector arm. Each of the first and second fasteners is configured to engage the respective frame member when the respective connector arm extends within said frame member.

Perimeter frame for sliding glass doors of the type including extruded metal profiles that are combined together circumferentially surrounding the glass sheet having two lateral profiles (1) arranged vertically and that fit on the sides of the glass sheet (4), a set of lower profiles (2) arranged horizontally on each side of the glass sheet (4) at its lower part and a set of upper profiles (3) arranged vertically in the upper area of the sheet glass (4), between which there is provided an opening (5) through which protrudes the upper portion of the glass (6), in which the clamps (7) that hold the sheet are applied.

Systems and methods for providing a universal window frame assembly. A window frame assembly can include a plurality of frame members, wherein at least one of the frame members comprises a first profile frame member and at least one of the other frame members comprises a second profile frame member. The at least one first profile frame member and the at least one second profile frame member seat together to form the frame assembly. Head and side jamb members of a window frame can have a common first profile, and a sill jamb member can have a second profile. The frame members can be connected with corner keys configured to engage one or more openings in the first and second profiles. The sill jamb member can provide a sill slope angle.

The present invention relates a corner assembly for use in a structural frame, said corner assembly comprises a housing defining a first and a second groove arranged at a predetermined angle to each other, and wherein the first groove is arranged for telescopically receiving and/or displacing a first elongated structural element and the second groove is arranged for telescopically receiving and/or displacing a second elongated structural element, and wherein the corner assembly further comprises a first and a second locking mechanisms arranged for independently of each other releasably fastening the first and second elongated structural element in the corresponding first and second groove. Since both the first and second locking mechanism is arranged for individually securing/fastening an elongated structural element to the corner assembly, the telescopic extension/displacement of each elongated structural element can be individually and independently adjusted irrespectively of the extension/displacement of the other elongated structural element.
