Description

Technical Field

[0001] The present invention relates to a door trim structure. More particularly, the present invention relates to a trim structure that forms both a part of a partition and a vertical upright for housing a door. The present invention also relates to a method for manufacturing such a trim structure. The present invention also relates to a method of fitting such a trim structure into an opening of a partition and into a part of the partition to form a vertical upright, as in the case of a standard door frame. Finally, the present invention relates to a door set comprising a door with such a trim structure. The present invention is particularly suitable for installing interior doors in any type of house during construction or renovation of a residence.

Background Art

[0002] During construction or renovation work, partitions are generally used to create the outline of a room. An opening is made in the partition to move from one room to another. An interior door is used to close the opening for soundproofing and heat insulation purposes. Whatever the type of door, to incorporate the door into the partition, the use of a door frame, also called a fixed frame, or a casing, which is a frame for housing the door, is necessary.

[0003] In a known manner, the door frame is sealed into the wall or partition using fixtures and constitutes the surround of the door. The door frame consists of two vertical uprights, one on each side of the opening, i.e., one on the left and one on the right, a top frame, and sometimes a sill. Together with the door, the door frame forms a door set. One of the vertical uprights has a strike plate casing in which the locking bolt of a locked door will fit inside. The other vertical upright is provided with a hinge leaf that allows the door to be assembled with the vertical upright and to move the door.

[0004] 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 can 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. The present invention is particularly applicable to this type of partition made of cardboard sheets or PVC sheets separated by a central layer.

[0005] In this specification, the term “partition” refers to a partition made of such composite panels.

[0006] There are various door frame and fitting solutions proposed according to the door material and wall configuration.

[0007] 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.

[0008] 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.

[0009] Figure 1A shows a partition 3 containing an opening that is closed by a door 7. A vertical member 2 is fitted to each end of this partition 3. The vertical member has a longitudinal profile of a substantially U-shaped cross section, including two lateral branches and a base. The U-shaped vertical member surrounds the partition 3, with the two lateral branches supporting the lateral walls of the partition and the base supporting the vertical edge surface of the partition, the width of the space between the two branches being 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.

[0010] Generally, wooden door frames of this type have the disadvantage of being less aesthetically pleasing because they have vertical members that protrude from the partition and the door.

[0011] 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 needed during on-site work.

[0012] 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 thus potentially weakening the partitions.

[0013] 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.

[0014] The door frame includes a first portion called jamb lining 4 and a second portion called jamb trimming 5, which works in conjunction with the jamb lining to allow the door frame to conform to the thickness of the partition. Similar to the embodiment in Figure 1A, the jamb lining and jamb trimming form a vertical member with a U-shaped cross section into which the partition 3 is incorporated. A reinforcing layer 8 may be interposed between the edge surface of the partition and the vertical member. The jamb lining has an assembly-free face that includes a projection 6 which functions as a door stop when the door 7 is closed.

[0015] The fitting method is as follows: First, the backing of the side post is fitted into the opening inside the partition, in contact with the partition. Next, the backing of the side post is secured with screws. Then, the edging of the side post is coated with adhesive and incorporated into the backing of the side post.

[0016] Such a door frame allows the thickness of the door frame to be adjusted according to the thickness of the partition. However, such a door frame still has the disadvantage of being somewhat unsightly because of the presence of vertical members that protrude from the partition and the door.

[0017] Furthermore, the materials used to construct the door frame, generally wood, are therefore different from the materials used for the partition. As a result, there is still a risk of cracks appearing as a result of thermal expansion at the joint between the partition and the door frame.

[0018] As shown in Figures 1A and 1B, conventional door frames have the disadvantage of being aesthetically unappealing because the vertical members of the door frame create additional thickness relative to the partition. One technique to conceal the door frame often involves painting it the same color as the partition, but this does not eliminate the difference in level between the door frame and the partition.

[0019] Furthermore, replacing an existing door frame with a new one is extremely difficult and expensive because it requires removing the door frame that is integrated into the partition.

[0020] Finally, due to the various materials used for partitions and standard door frames, cracks may develop within the partition as a result of thermal expansion at the joint between the partition and the door frame. [Overview of the project] [Problems that the invention aims to solve]

[0021] The object of the present invention is to provide a novel trim structure that improves the aesthetic appearance of the assembly by making it invisible separately or even within the room's decor, while simultaneously improving the structural and mechanical quality of its integration into the partition. Furthermore, this novel trim structure simplifies door fitting, thus saving on on-site work time and costs. Finally, by being made from the same material as the adjacent partition, the novel trim structure eliminates the problem of thermal expansion that could cause cracks in the wall.

[0041] Other features, details, and advantages of the present invention will become apparent upon reading the detailed description below and examining the accompanying drawings. [Brief explanation of the drawing]

[0042] [Figure 1A] This is a top-down cross-sectional view of a door frame designed for conventional fitting using prior art technology. [Figure 1B] This is a top-down cross-sectional view of a door frame, including the side post lining and side post trim for the so-called second-fix fitting of the conventional technology. [Figure 2] This is a perspective view of a trim structure according to one embodiment of the present invention. [Figure 3] This is a top-down cross-sectional view of the trim structure shown in Figure 2, which fits into the lateral end of the partition and receives the door. [Figure 4]Figure 2 is a partial cross-sectional perspective view of two trim structures positioned on either side of the opening to form left and right lateral vertical members, respectively, to receive a door and a portion of a lateral partition. These two trim structures are mounted to a metal framework and assembled together with a partition positioned in the upper portion of the opening. [Figure 5] This is an enlarged view of Figure 4, showing the area of ​​the connection between the trim structure and the end of the upper partition. [Figure 6] Figure 4 is a perspective view showing the door integrated into the opening. [Modes for carrying out the invention]

[0043] The figures and the following description contain elements that are essentially constant in nature. Therefore, they can be helpful not only in better understanding the present invention, but also, where applicable, in defining it.

[0044] For clarity, one identical numerical reference is used in Figures 2 to 6 to illustrate one identical element of the trim structure according to the present invention.

[0045] The present invention relates to a trim structure that is assembled with a partition and receives a door, particularly an interior door.

[0046] In this specification, the term “partition” refers to any type of building partition wall or wall that defines a space.

[0047] Throughout this application, the term “interior” refers to elements of the trim structure that are not visible, and the term “exterior” refers to elements of the trim structure that are visible. The terms “upper” and “lower” should be understood in relation to the arrangement of the trim structure relative to the floor to which it is attached.

[0048] According to one embodiment of the present invention, which will be described later with reference to Figures 2 and 3, the trim structure 10 comprises a first lateral wall 11 and a second lateral wall 12. The two walls are spaced apart by a thickness e1. The two walls 11 and 12 are connected by a lateral end wall 13. The lateral end wall is perpendicular to the first and second walls.

[0049] This trim structure 10 is intended to be fixed to a metal framework that defines the opening O shown in Figure 4, on the one hand to form a portion of partitions 30, 31, and 32, and on the other hand to form a vertical member 80 for receiving an interior door.

[0050] According to one advantageous feature of the present invention, the two walls of the trim structure 10 are spaced apart by a thickness e1, and the thickness e1 is equal to the thickness e2 of the partition adjacent to the trim structure. Thus, when the trim structure is attached to the metal framework 50, the outer surfaces of the two walls are coplanar with the outer surface of the adjacent partition. Generally, the standard thickness of the partition is 50 mm, 72 mm, or 98 mm.

[0051] The lateral end wall 13 has an inner surface oriented toward the adjacent partition 30 and an outer surface oriented toward the door 70. The outer surface includes a flat surface 14 and a protruding element 15, the protruding element 15 being perpendicular to the flat surface 14. As shown in Figures 2 and 3, the flat surface 14 has a thickness b1, which is equal to the thickness b2 of the door, which is generally between 29 and 40 mm. Thus, when the door is closed, the flat surface 14 is in contact with the edge of the door, and the protruding element 15 forms the support surface of the door. More specifically, the protruding element 15 has a first outer side 15a and a second outer side 15a'. The first outer side 15a constitutes the door stop surface of the door. The second side 15a' has a thickness c1. The total thickness of the lateral end wall (b1 + c1) is equal to the thickness e1 of the trim structure. Therefore, during on-site work, it is possible to change the thickness b1 of the flat surface due to the thickness b2 of the door, and the thickness c1 of the second side 15a', and adjust the total thickness b1+c1 based on the thickness e2 of the partition adjacent to the structure 30.

[0052] As shown in Figures 2 and 3, the two lateral walls 11 and 12 extend directly and perpendicularly from the end of the lateral end wall 13 without interruption. Thus, a portion of the lateral wall 11 is formed by the outside of a protruding element that is not perpendicular to the flat surface.

[0053] Therefore, when the trim structure according to the present invention is attached to the metal framework of the opening, the lateral walls 11, 12 form part of the partition 30, and the lateral end wall 13 forms one of the vertical members for receiving the door. The lateral walls 11, 12 form the visible portion of the trim structure, and the lateral end wall 13 forms the portion that is not visible when the door is closed. The lateral walls 11, 12 form outer surfaces that are coplanar with the two outer surfaces 41, 42 of the adjacent partition 40, respectively, which provides an aesthetic advantage over conventional door frames. Specifically, once the finishing work on the lateral walls of the trim structure and the adjacent partition is completed, the trim structure becomes invisible.

[0054] According to one particularly advantageous technical feature of the present invention, the trim structure 10 is preferably made from the same material as the adjacent partition, i.e., the composite panel. Within the scope of the meaning of this application, a composite panel is a panel comprising two facing materials separated by a core layer. The facing materials may generally include one or more sheets made from materials such as cardboard or PVC (polyvinyl chloride). The core layer or core may be made from any type of material such as gypsum, foam, cardboard, or cement. Such a composite panel offers the advantages of being made from lightweight, easy to handle and install, and low-cost materials. By making the lateral walls of the trim structure from the same material as the adjacent partition, it is possible to eliminate the problem of thermal expansion in the joint area between the trim structure and the partition, and thus prevent the appearance of cracks that could weaken the partition.

[0055] The trim structure is formed from one or more composite panels that are assembled and fixed together.

[0056] In the embodiment shown in Figure 2, the trim structure includes a first composite panel 16 and a second composite panel 17.

[0057] The first panel 16 forms the first lateral wall 11 and the protruding element 15. The protruding element is formed from the longitudinal edge of the first panel 16. Particularly formed are the first portion 15' and the second portion 15'' of the protruding element 15, which are formed by the first bend 23 and the second bend 24 of the longitudinal edge of the first panel, respectively, toward the surface of the composite panel 16 that forms the inner surface of the lateral wall 11. The first portion 15' is perpendicular to the second portion 15'', and the second portion 15'' is perpendicular to the other portion of the panel that forms the first lateral wall 11.

[0058] The second panel 17 forms the second lateral wall 12 and the flat surface 14. The flat surface 14 is formed from the longitudinal edge of the second panel 17. Specifically, the flat surface 14 is formed from the bent portion 25 and is perpendicular to the other portion of the second panel 17 that forms the second lateral wall 12.

[0059] The first panel 16 and the second panel 17 are assembled and fixed together by a fixing piece 21. This fixing piece 21 is also preferably made from the same material as the composite panels forming the trim structure, for example, plaster or two pieces of cardboard separated by a cardboard core. The fixing piece 21 has a substantially parallelepiped shape. The inner side of the flat surface 14b and the inner side of the protruding element 15b are fixed to one side of the fixing piece 21 which is oriented toward the door. This fixing is done using conventional fastening means with screws or adhesive.

[0060] According to one embodiment of the present invention not shown in the figures, the trim structure 10 is a single piece and may be formed from a single composite panel. The lateral end wall is then formed from four bends along four 45° grooves, which are created, for example, by making V-shaped cross-sectional cutouts in the composite panel.

[0061] Depending on the requirements and use of the room within the dwelling, the trim structure may further include at least one metal reinforcing piece 22 positioned within the space E formed by two lateral walls 11, 12 and a lateral end wall 13. This metal reinforcing piece has a U-shaped cross-section. The base of the reinforcing piece is fixed to the side of a fixing piece 21 oriented toward an adjacent partition, for example. Two lateral branches of the reinforcing piece are fixed to the lateral walls 11 and 12.

[0062] To make the composite panel more rigid, it is also possible to cover at least one of the sheets of the composite panel in the trim structure with a reinforcing layer.

[0063] By fabricating the trim structure from composite panels, similar to the adjacent partitions, it becomes possible to form a separate or even invisible door frame, thus offering aesthetic advantages over the prior art. Furthermore, this trim structure also simplifies the fitting process. Specifically, it only requires securing the trim structure to the metal framework with screws, similar to the fitting of standard partitions.

[0064] The trim structure can form vertical members suitable for doors with square edges or doors with grooves.

[0065] A method for manufacturing a trim structure comprising two composite panels is described below in this specification.

[0066] The method for manufacturing the trim structure includes the following steps:

[0067] For example, a first lateral wall 11 and a protruding element 15 are formed in a first composite panel 16. Two 45° V-shaped grooves are fabricated in the first panel, and the two grooves are parallel to the longitudinal edge of the first panel. To do so, two V-shaped notches are fabricated in the composite panel. Preferably, the grooves are formed without notches in the lateral wall to form the outer surface of the trim structure. Thus, the outer surface of the panel remains a flat, single surface. Adhesive is applied to the two grooves, and the panel is bent along the two grooves and bonded together to form the first lateral wall 11 and the protruding element 15.

[0068] A second lateral wall 12 and a flat surface 14 are formed in the second composite panel 17. A 45° V-shaped groove is fabricated in the second panel, and the groove is parallel to the longitudinal edge of the second panel. To do this, a V-shaped cross-section cutout is fabricated in the composite panel without cutting into the lateral wall to form the outer surface of the structure. Adhesive is applied to the groove, and the panel is bent along the groove and bonded along the groove to form the second lateral wall 12 and the flat surface 14.

[0069] According to one embodiment of the present invention, the two panels are then assembled and fixed together using a fixing piece 21 by adhesive or screw fastening. Specifically, the inner side 14b of the flat surface 14 and the inner side 15b of the protruding element 15 are fixed to one side of the fixing piece 21 to hold the two panels together.

[0070] In one variant configuration, the two panels are not assembled during manufacturing but are fixed together when the trim structure is fitted into the metal framework. Therefore, the thickness e1 formed by the two side walls of the trim structure can be adjusted according to the thickness of the adjacent partition 40.

[0071] Although not shown in the drawings of this application, the trim structure, specifically the lateral end wall, may include at least one housing for receiving a strike plate casing for receiving door locking bolts, or a hinge leaf for assembling a door to the trim structure and for allowing the door to move.

[0072] Next, a method for fitting the trim structure of the present invention to form a partition for an opening on the one hand and a vertical member for housing a door on the other hand will be described below with reference to Figures 4, 5, and 6.

[0073] As shown in Figure 4, the first lateral partition 31 formed by the first trim structure, the second lateral partition 32 formed by the second trim structure, and the upper partition 60 define the opening O for which the door 70 closes.

[0074] To erect the lateral partitions 31 and 32, a metal framework 50 is first formed for each trim structure. Each metal framework, as in the case of a standard framework, includes, for example, two metal vertical members 52, a metal horizontal rail, and a lower horizontal rail 51. The opening O is defined by the two metal vertical members 52. As in the case of conventional partition erection, the gap between the two composite panels that are to form the trim structure can be filled with thermal insulation / soundproofing material 53 to allow for the installation of equipment.

[0075] According to one method for fitting a trim structure of the present invention, the assembly of the trim structure is performed while the trim structure is fitted into the metal framework.

[0076] A first composite panel 16 is supplied, comprising a lateral wall 14 and a protruding element 15. The first composite panel is then fixed to the metal framework by fixing the first lateral wall 11 to the metal framework using screws to form a first outer surface of the partition, and fixing means to fix the inside 15b of the protruding element 15 to one end of the horizontal rail 51 and the vertical member 52.

[0077] A second composite panel 17 is supplied, comprising a second lateral wall 12 and a flat surface 14. The second lateral wall is fixed to the metal framework to form a second outer surface of the lateral partition, and the inner surface 14b of the flat surface 14 is fixed to the metal framework, i.e., one end of the horizontal rail 51 and the vertical member 52.

[0078] The lateral end wall 13, having a flat surface and protruding elements, can function as a vertical member 80, as in a standard door frame, and may include a strike plate casing that receives the locking bolts of the door 70.

[0079] To form a second lateral partition 32 and a second vertical member 80, a nearly identical second trim structure is fitted into the metal framework in the same manner as the first trim structure. The lateral end walls of the trim structure in the example shown in Figure 6 are equipped with hinge leaves for assembling the door with the vertical member and for allowing the door to move. Thus the door can pivot around the hinge, and when the door is closed, one edge of the door is in contact with the flat surface 14 and the other edge of the door abuts against the protruding element 15.

[0080] Next, the upper metal framework 60 is placed above. Similar to the metal framework of the lateral partition, the upper metal framework 60 consists of vertical members and horizontal rails. The upper and lower rails, positioned facing the lateral end wall, have ends in cross-sections shaped to complement the shape of the lateral end wall of the trim structure. When the upper framework is assembled with the trim structure, the ends of these horizontal rails support the lateral end wall. The composite panels are then fixed to each side of this upper metal framework to form the two outer surfaces of the upper partition 33. As shown in Figure 6, the partitions 31 and 32 formed by the trim structure have outer surfaces that are coplanar with the upper partition.

[0081] Although not shown in Figure 6, in an example where a standard lateral partition 40 is fitted adjacent to partitions 31 and 32 formed by a trim structure, the outer surfaces of partitions 31 and 32 are also coplanar with the outer surfaces of the adjacent standard lateral partitions.

[0082] In one modified configuration, a fixing piece 21 is interposed between the metal framework and the inside of the lateral end wall 13. The fixing piece 21 is mainly a parallelepiped component fixed to one end of the vertical member 52 and the horizontal rail 51. The width L1 of the fixing piece is substantially equal to the width L2 of the horizontal rail. The inside 14b of the flat surface and the inside 15b of the protruding element are fixed to the fixing piece rather than directly to the metal framework.

[0083] According to another method for fitting the trim structure of the present invention, the trim structure is a single-piece structure formed from composite panels or structures that are already assembled before being fitted into the metal framework. Thus, the two composite panels are first assembled and fixed together using fixing pieces 21.

[0084] Next, the first metal framework is surrounded by a first trim structure such that the lateral walls 11 and 12 support the metal framework to form the first and second outer surfaces of the first lateral partition 31, respectively, and one side of the fixed end 21 supports the metal vertical member of the opening. The trim structure is then fixed to the metal framework using known fastening means.

[0085] To form the second lateral partition 32 and the vertical members of the door frame, nearly identical trim structures are fitted into the metal framework in the same manner as the first trim structures, and the metal framework is surrounded by the trim structures.

[0086] Therefore, once fitted, the trim structure according to the present invention can conceal the door frame that receives the door, i.e., the portion that functions as a vertical member, and thus improve the aesthetic appearance. Furthermore, by fabricating this trim structure from the same material as the adjacent partition, it is possible to increase the overall strength of the assembly formed by the door frame and partition with respect to thermal expansion issues. Moreover, the novel trim structure can be adapted to existing fitting techniques, i.e., conventional fitting or second-fix fitting, according to the user's requirements.

[0087] Furthermore, since the trim structure forms both part of the partition and one of the vertical members of the door frame, it also simplifies on-site work and reduces labor costs.

[0088] The fact that the trim structure is made from composite panels also allows for cost reductions compared to conventional wooden door frames. [Industrial applicability]
