A composed element includes at least two panel-shaped elements, such as a locking tongue and groove connection, that are arranged to be coupled to each other at an angle, either directly or indirectly by means of an intermediate piece. The connection includes, at least at one of the panel-shaped elements, a tongue or groove, cooperable with a groove or tongue provided on the other panel-shaped element or on the intermediate piece. The tongue includes a split tongue, with at least a first part and a second part, and a slit located therebetween. A locking part is located at the outer side of at least said first part wherein the slit, seen in cross-section of the tongue, defines at least one side, the course of which, seen in cross-section, deviates from the main direction belonging to the tongue.

A ventilated window frame comprising; a frame having a plurality of slots along an interior edge and a channel having a first opening and a second opening, a permeable layer fitted within one of the plurality of slots distal to the first edge of the frame, a permeable layer secured within one of the plurality of slots distal to the second edge of the frame, a non-permeable layer secured within one of the plurality of slots between the first and second permeable layers, wherein the first opening of the channel is between the first permeable layer and the non-permeable layer and the second opening of the channel is located between the second permeable layer and the non-permeable layer, a filter inserted within the first opening of the channel, and a fan fitted between the first opening and the second opening of the channel.

A frame assembly for a doorway defined by two substantially vertical sides and a substantially horizontal side comprises a header jamb having a top surface, a bottom surface, and one or two header jamb rebates. The top surface of the head jamb is adapted for fixedly mounting to the substantially horizontal side of the doorway and the header jamb rebates located on the bottom surface across the length of the header jamb define a header soffit. The frame assembly comprises two upright jambs each having an outer surface and a top end. The outer surface of each of the upright jambs is adapted for fixedly mounting to one of the two substantially vertical sides of the doorway. The top end of each of the upright jambs have a slot for receiving a portion of the header soffit such that, when assembled, the header soffit engages in the slots.

Disclosed are a frame assembly structure of a wooden doors and windows and a corner assembly method. The window includes, at least, a window frame or a casement window frame mainly formed by joining adjacent profile frame strips via a corner assembler on adjacent connecting end surfaces. The connecting end surfaces of two adjacent profile frame strips are respectively configured to be cross sections of 0 to 180. A positioning notch of the corner assembler is at least provided on the cross sections. Two half corner assemblers of the corner assemblers are respectively embedded and fixed into the positioning notches on the adjacent cross sections. The two half corner assemblers are connected by an intermediate fastening piece and a fastening bolt to form a complete corner assembler, and the two adjacent profile frame strips are connected tightly and fixedly. The frame assembly structure is easy to assemble.

A configurable door system includes a first and second door panel, an astragal, and a frame. The frame defines a first axis and is configured to pivotally support the door panels in a first configuration of the door system and in a second configuration of the door system. The first door panel is disposed to one side of the second door panel along the first axis within the frame in both the first and second configurations. The door system, in the first configuration, includes the astragal fixed to the first door panel and releasably attaches the first door panel to the frame, and the second door panel is releasably secured to the astragal. The door system, in the second configuration, includes the astragal fixed to the second door panel and releasably attaches the second door panel to the frame, and the first door panel is releasably secured to the astragal.

A door panel comprising a body having front and rear door skins sandwiching, at least partially, two stiles, which together delimit an interior for injection of filling material. At least one of the stiles comprises a hollow structure with a partitioned hollow interior that extends along substantially the entire length of the body to offer mechanical strength to the door and to provide foundation for installing door fittings.

A composed element includes at least two panel-shaped elements, such as a locking tongue and groove connection, that are arranged to be coupled to each other at an angle, either directly or indirectly by means of an intermediate piece. The connection includes, at least at one of the panel-shaped elements, a tongue or groove, cooperable with a groove or tongue provided on the other panel-shaped element or on the intermediate piece. The tongue includes a split tongue, with at least a first part and a second part, and a slit located therebetween. A locking part is located at the outer side of at least said first part wherein the slit, seen in cross-section of the tongue, defines at least one side, the course of which, seen in cross-section, deviates from the main direction belonging to the tongue.
