Description

This invention relates to door trim structures. More specifically, it relates to trim structures that form both a portion of a partition and a vertical upright for housing a door. The invention also relates to a method for manufacturing such trim structures. Furthermore, it relates to a method for fitting such trim structures into the opening of a partition and a portion of the partition to form a vertical upright, similar to that in a standard door frame. Finally, the invention relates to a door set comprising a door with such trim structures. The invention is particularly suitable for installing interior doors in any type of house during construction or renovation. During construction or renovation, partitions are generally used to define the contours of rooms. Openings are created within these partitions to allow movement from one room to another. Interior doors are used to close these openings for sound and heat insulation purposes. Regardless of the type of door, incorporating it into a partition requires the use of a door frame, also called a fixed frame, or a casing, which is a frame for housing the door. In known methods, the door frame is sealed within a wall or partition using fasteners, forming the door frame. The door frame consists of two vertical members, one on each side of the opening (i.e., one on the left and one on the right), a top frame, and sometimes a threshold. Together with the door, the door frame forms the door set. One of the vertical members contains a strike plate casing, which houses the locking bolts of the door with a lock. The other vertical member contains a hinge leaf that allows the door to be assembled with the vertical member and to move. There are various types of partitions with different structures and thicknesses to which door frames can be attached. One type of partition that is very popular in the field of architecture and renovation is a partition made of composite panels fixed to a metal framework. Each composite panel has a structure formed of two facing materials separated by a central layer. The facing materials generally include one or more sheets made of materials such as cardboard or PVC (polyvinyl chloride). The central layer or core can be made of any type of material such as plaster, foam, cardboard, or cement. This partition is particularly suitable for creating spatial contours within a house. Furthermore, it is very easy to create openings within such a partition. This invention is particularly applicable to this type of partition made of cardboard sheets or PVC sheets separated by a central layer. In this specification, the term "partition" refers to a partition made of such composite panels. There are various door frame and fitting solutions proposed according to the door material and wall configuration. In the case of partitions, conventional door frame systems consist of enclosing the partition, and there are mainly two fitting techniques used depending on the type of door frame selected. Figure 1A shows a first embodiment of a prior art door frame 1, which requires a fitting known as a "traditional" fitting. Such a door frame fitting is performed before or during the installation of the partition. Figure 1A shows a partition 3 containing an opening that is closed by a door 7. Vertical members 2 are fitted to each end of the partition 3. The vertical members have a substantially U-shaped longitudinal profile with a cross-section including two lateral branches and a base. The U-shaped vertical members surround the partition 3, with the two lateral branches supporting the lateral walls of the partition and the base supporting the vertical edge of the partition. The width of the space between the two branches is substantially the same as the thickness of the partition. The base has a surface for assembly with the door. This surface includes a projection that functions as a door stop when the door 7 is closed. Generally, wooden door frames of this type have the disadvantage of being less aesthetically pleasing due to the presence of vertical members protruding from the partition and door. Furthermore, as shown in Figure 1A, the width of the door frame is fixed and must be selected according to the thickness of the partition. Therefore, due to the varying thicknesses of the partitions, a large variety of door frame types are required during on-site work. Finally, the difference in materials used for the door frame compared to the partition material can lead to expansion problems caused by temperature changes, resulting in cracks appearing at the joints between the door frame and partitions, and consequently, weakening of the partitions. Figure 1B shows a second embodiment of a standard door frame. Such a door frame is installed after all other work, such as partitions and flooring, is complete. This is the so-called "second-fix" technique. The door frame includes a first portion called jamb lining 4 and a second portion called jamb trimming 5, which
