A tightly closed structure of a glass door comprises a doorframe and a first door panel. An upper containing groove is transversely arranged at the top of the doorframe and a lower containing groove is transversely arranged at the bottom of the doorframe. An upper frame strip and a lower frame strip that protruding from the first door panel are respectively arranged on the upper edge and the lower edge at the direction which the first door panel faces to the doorframe. The upper frame strip is embedded in the upper containing groove and the lower frame strip is embedded in the lower containing groove. When the first door panel and the doorframe are fastened, the upper frame strip and the lower frame strip are fastened into the upper containing groove and the lower containing groove at the same time, so that the upper frame strip and the lower frame strip can be hidden and make the first door panel and the doorframe to be tightly closed.

The present invention is directed to a method of making a door having first and second door facings and an internal doorframe. An interior side of a first facing is coated with quick acting adhesive. A frame is placed on the coated interior side about the periphery of the first facing. The frame is then coated with quick acting adhesive. An interior side of a second facing is placed on the coated frame. The facings and frame assembly are then compressed to form a door. The present invention also provides for an automated system of making the door.

A partition system (10) for dividing a space, comprising a frame (11) and one or more partition panels (12) mountable on the frame, wherein the frame comprises a plurality of main profiles (100) which comprises at least one plurality of perimetric profiles (110) configured to be fixed to a surface of the space; one or more perimetric profiles are constituted of a main material which is thermoplastic polyolefin mixture-based. Each main profile delimits a first front hollow (102) which, in use, receives an edge (13) of at least one of the partition panels. The frame comprises a plurality of covering profiles (200) which are couplable by means of a snap joint to the plurality of main profiles, and which comprises a plurality of first covers (201) couplable in such a way as to close the first front hollow at the first lateral side obstructing removal of the partition panel.

A frame assembly for retaining an IG unit in an opening in a door or other panel structure may include a first frame configured to engage a surface of the door or other panel structure about a periphery of the opening and to engage the IG unit about an outer periphery thereof, and having a first coupling portion, a second frame integral with, or configured to engage, an opposite surface of the door about a periphery of the opening and to engage the IG unit about the outer periphery thereof, and having a second coupling portion, and an alignment member to engage each of the first and second coupling portions, between the periphery of the opening and the outer periphery of the IG unit, to align the first and second coupling portions with one another.
