       DETAILED DESCRIPTION 
       [0065]    In embodiments, there are disclosed decorative foldable frames, decorative foldable frame assemblies, decorative foldable door members and methods for installing and/or using the same. 
         [0066]    Referring now to the drawings, and more particularly to  FIG. 1 , there is shown a perspective view of a wall  9  defining a door opening  11 . It is to be mentioned that the door opening  11  may also be understood to be a window opening, a garage opening and any other suitable opening for receiving a decorative foldable door frame  10  as described below. The opening  11  may be defined in the wall  9  by peripheral external surfaces  14   a ,  14   b  and an internal surface  12  which has a lateral length  13  (i.e., the thickness of the wall  9  or of the structure).  FIG. 1  shows that edges  15   a ,  15   b  are defined at meeting points of the peripheral external surfaces  14   a ,  14   b  and the internal surface  12 . 
         [0067]    Referring now to  FIGS. 2 ,  3  and  4 , there is shown the decorative foldable door frame  10 . The decorative foldable door frame  10  is to be interfacing with the peripheral external surfaces  14   a ,  14   b  and the internal surface  12  of the wall  9  defining the door opening  11 . The decorative foldable door frame  10  includes internal mounting elements  16   a ,  16   b . Each one of the internal mounting elements  16   a ,  16   b  defines an internal mounting surface  18   a ,  18   b  to be interfacing with the internal surface  12  and external surfaces  20   a ,  20   b . The decorative foldable door frame  10  further includes external mounting elements  24   a ,  24   b , where each one of the external mounting elements  24   a ,  24   b  is adjacent to longitudinal sides  26 ,  27  of the internal mounting elements  16   a ,  16   b.    
         [0068]    The external mounting elements  24   a ,  14   b  include or define internal mounting surfaces  28   a ,  28   b  which can fixedly interface with the peripheral external surfaces  14   a ,  14   b  respectively and external surfaces  30   a ,  30   b.    
         [0069]    Additionally, the decorative foldable door frame  10  includes foldable layers  22   a ,  22   b . As shown in  FIG. 2 , the foldable layer  22   a  covers or layers the external surface  30   a  of the external mounting element  24   a  and the external surface  20   a  of the internal mounting element  16   a , totally, or partially. On the other hand, the foldable layer  22   b  covers or layers the external surface  30   b  of the external mounting element  24   b  and the external surface  20   b  of the internal mounting element  16   b , totally, or partially. 
         [0070]    Still referring to  FIG. 2 , the foldable layers  22   a ,  22   b  totally covers the external surfaces  20   a ,  20   b ,  30   a ,  30   b  of the internal mounting elements  16   a ,  16   b  and the adjacent external mounting elements  24   a ,  24   b.    
         [0071]    According to an embodiment, the foldable layers  22   a ,  22   b  may be integrally formed for allowing the decorative foldable door frame  10  to fold and unfold to adopt any positions between a non-installed position ( FIGS. 2 ,  3  and  4 ) and an interfacing position ( FIG. 5 ). 
         [0072]    Now referring to  FIGS. 3 and 4 , there is shown the internal mounting elements  16   a  with the external mounting element  24   a  ( FIG. 3 ) and the internal mounting elements  16   b  with the external mounting element  24   b  ( FIG. 4 ). The internal mounting elements  16   a ,  16   b  each defines respective longitudinal opposed ends  36   a ,  37   a ,  36   b ,  37   b . As shown, the end  37   a  of the internal mounting element  16   a  includes a mating connector  38  ( FIG. 3 ) which can releasably connect with a corresponding mating connector  40  on the end  36   b  of the internal mounting element  16   b  ( FIG. 4 ). However, it is to be noted that the internal mounting elements  16   a ,  16   b  may be integrally formed such that a decorative foldable door frame  10  may include only one internal mounting element and adjacent external mounting elements  24   a ,  24   b  without any mating connectors of the internal mounting element. 
         [0073]    Furthermore, the internal mounting element  16   a  defines a longitudinal edge  42  as the internal mounting element  16   b  defines a longitudinal edge  46  ( FIG. 2 ). Also, the external mounting elements  24   a ,  24   b  each define a corresponding edge  44 ,  48  ( FIG. 2 ) for interfacing with the longitudinal edges  42 ,  46  of the internal mounting elements  16   a ,  16   b  when the decorative foldable door frame  10  adopts an interfacing position ( FIG. 5 ). 
         [0074]    Now referring to  FIGS. 2 ,  3 ,  4  and  5 , the longitudinal edge  42  of the internal mounting element  16   a  and the longitudinal edge  46  of the internal mounting element  16   b  define a 45° longitudinal edge. Moreover, the corresponding edge  44  of the external mounting element  24   a  and the corresponding edge  48  of the external mounting element  24   b  define a corresponding 45° longitudinal edge for interfacing with the longitudinal edges  42 ,  46  of the internal mounting elements  16   a ,  16   b  when adopting the interfacing position ( FIG. 5 ). 
         [0075]    Furthermore, the internal mounting elements  16   a ,  16   b  interact with the external mounting elements  24   a ,  24   b  for creating a 90° angle ( FIGS. 3 and 4 ). As shown on  FIG. 5 , the 45° edges  42 ,  46  and the corresponding 45° edges  44 ,  48  interact and interface to position the decorative foldable door frame  10  in its interfacing position. 
         [0076]    Also, the internal mounting elements  16   a ,  16   b  and/or the external mounting elements  24   a ,  24   b  may be fixed to the internal surface  12  or the peripheral external surfaces  14   a ,  14   b  ( FIGS. 1 and 5 ) of wall  9  defining the door opening  11  using, without limitation, screws, nails, glue, dove tail elements and any other suitable fastener for fixing the internal mounting elements  16   a ,  16   b  and/or the external mounting elements  24   a ,  24   b  to the internal surface  12  or to the peripheral external surfaces  14   a ,  14   b . More preferably, the internal mounting elements  16   a ,  16   b  are interfacing with the internal surface  12  and the external mounting elements  24   a ,  24   b  are fixed to the peripheral external surfaces  14   a ,  14   b.    
         [0077]    According to an embodiment, the internal mounting elements  16   a ,  16   b  and the external mounting elements  24   a ,  24   b  may include, without limitation, a medium-density fiberboard material (i.e., MDF), a low-density fiberboard material (i.e., LDF), a high-density fiberboard material (i.e., HDF), a particle board, a wood material, a metallic material, a polymeric material, any combinations, and any other suitable material for use of the decorative foldable door frame  10  in indoor conditions or in outdoor conditions (or in both indoor and outdoor conditions). 
         [0078]    According to another embodiment, the foldable layers  22   a ,  22   b  may include, without limitation, a thermoplastic material, a plastic material, a polymeric material, a metallic material, a linerboard material, any combinations, and any suitable material for allowing the decorative foldable door frame  10  to be folded and unfolded between a non-installed position ( FIGS. 2 ,  3 ,  4 ) and an interfacing position ( FIG. 5 ). Thus, the foldable layers  22   a ,  22   b  need to be flexible and strength such as to fold and unfolded without damage or with reduced risks of damages. 
         [0079]    As shown in  FIGS. 2-5 , the foldable layers  22   a ,  22   b  may cover the internal mounting surfaces  18   a ,  28   a ,  18   b ,  28   b  of the internal mounting elements  16   a ,  16   b  and of the external mounting elements  24   a ,  24   b . However, it is to be noted that the foldable layers  22   a ,  22   b  may partially or totally covers the internal mounting surfaces  18   a ,  28   a ,  18   b ,  28   b  of the internal mounting elements  16   a ,  16   b  and of the external mounting elements  24   a ,  24   b.    
         [0080]    According to another embodiment, the foldable layers  22   a ,  22   b  may also cover the external surfaces  20   a ,  30   a ,  20   b ,  30   b  of the internal mounting elements  16   a ,  16   b  and of the external mounting elements  24   a ,  24   b . It is to be noted that in both cases, the foldable layers  22   a ,  22   b  may be weakened at longitudinal lines (not shown) corresponding to the longitudinal sides  26 ,  27  respectively between the internal mounting element  16   a  and the external mounting element  24   a  and the internal mounting element  16   b  and the external mounting element  24   b . In this case, the decorative foldable door frame  10  may fold and unfold to adopt any position between the non installed position ( FIGS. 2-4  and  3 ) and the interfacing position ( FIG. 5 ). 
         [0081]    According to another embodiment, the foldable layers  22   a ,  22   b  may partially or totally cover the external surfaces  20   a ,  30   a ,  20   b ,  30   b  of the internal mounting elements  16   a ,  16   b  and of the external mounting elements  24   a ,  24   b.    
         [0082]    In the scenario where the foldable layers  22   a ,  22   b  cover the internal mounting surfaces  18   a ,  28   a ,  18   b ,  28   b  of the internal mounting elements  16   a ,  16   b  and the external mounting elements  24   a ,  24   b , the foldable layers  22   a ,  22   b  may further include at least one foldable fin (i.e., or projecting portion, not shown) outwardly extending from the foldable layers  22   a ,  22   b.    
         [0083]    It is to be notated that, the internal mounting element  16   a  adjacent with the external mounting element  24   a  via the foldable layer  22   a  and the internal mounting element  16   b  adjacent with the external mounting element  24   b  via the foldable layer  22   b  may come into a kit for allowing a user to releasably connect them, via the mating connectors  38  and  40  of the internal mounting elements  16   a ,  16   b.    
         [0084]    It is to be noted that the ends of the external mounting elements  24   a ,  24   b  opposite the ends  37   a ,  36   b  with the mating connectors each include a mating connector for releasably connecting with a corresponding mating connector (not shown) of a decorative element (i.e., a decorative molding).

The decorative foldable door member  100  also includes external mounting elements  118   a ,  118   b  adjacent to each longitudinal ends  120 ,  122  of the internal mounting element  112 . The external mounting elements  118   a ,  118   b  define external surfaces  124   a ,  124   b  and internal interfacing surfaces  126   a ,  126   b . One internal interfacing surface  126   a  of the external mounting elements  118   a  is for interfacing with the internal interfacing surface  126   b  of the external mounting element  118   b  when the decorative foldable door member  100  is in an interfacing position ( FIGS. 6 ,  7  and  9 ). The decorative foldable door member  100  further includes a foldable layer  128  which covers the external surfaces  124   a ,  124   b  and  116  of the external mounting elements  118   a ,  118   b  and of the internal mounting element  112 . It is however to be noted that a foldable layer  128  may also covers the internal interfacing surfaces  114   a ,  114   b ,  126   a  and/or  126   b  of the internal mounting element  112  and of the external mounting elements  118   a ,  118   b.    
         [0086]    According to  FIGS. 6-9 , the foldable layer  128  covers the external surface  116  of the internal mounting element  112  and the external surface  124   a ,  124   b  of the external mounting elements  118   a ,  118   b . The foldable layer  128  is integrally formed for allowing the decorative foldable door member  100  to fold and unfold to adopt any position between a non-interfacing position ( FIG. 8 ) and an interfacing position ( FIGS. 6 ,  7  and  9 ). 
         [0087]    When adopting the interfacing position ( FIGS. 6 ,  7  and  9 ), the internal interfacing surfaces  126   a ,  126   b  of the external mounting elements  118   a ,  118  are interfacing for creating a mating connector  130  at a distal end  132  ( FIG. 9 ) of the decorative foldable door member  100  to receive at least one corresponding mating connector  134 . In other words, each one of the external mounting elements  118   a ,  118   b  defines a recess  129   a ,  129   b  at an end opposed to the internal mounting surface  112  to be aligned with the other one of the recess  129   a ,  129   b  when in the interfacing position and thereby providing the decorative foldable door member  100  with a mating connector  130  which has a suitable shape and configuration to releasably match with a corresponding mating connector  134  of another door member  135 . 
         [0088]    The external mounting elements  118   a ,  118   b  define a corresponding edge  140  for interfacing with the internal interfacing surface  114   a  of the internal mounting element  112  and a corresponding edge  142  for interfacing with the internal interfacing surface  114   b  of the internal mounting element  112  when the decorative foldable door member adopts the interfacing position ( FIGS. 6 ,  7  and  9 ). 
         [0089]    The internal interfacing surface  114   a  and the internal interfacing surface  114   b  define in  FIGS. 6-9  a 45° longitudinal edge. The internal interfacing surfaces  114   a ,  114   b  of the internal mounting element  112  include a 45° longitudinal edge for interfacing with the corresponding edges  140 ,  142  of the external mounting elements  118   a ,  118   b  respectively. However, it is to be noted that any suitable angle, shape and configuration may be used such as to allow the edges  140 ,  142  of the external mounting elements  118   a ,  118   b  to interface with the internal interfacing surfaces  114   a ,  114   b  of the internal mounting element  112  when the decorative foldable door member adopts its interfacing position. 
         [0090]    The internal mounting element  112  interacts with the two external mounting elements  118   a ,  118   b  for creating a 90° angle. 
         [0091]    According to an embodiment, the internal mounting element  112  and the external mounting elements  118   a ,  118   b  may include, without limitation, a medium-density fiberboard material, a wood material, a metallic material, a polymeric material, any combination, and any other suitable material. 
         [0092]    According to another embodiment, the foldable layer  128  may include, without limitation, a thermoplastic material, a plastic material, a polymeric material, a metallic material, a linerboard material, any combination, and any other suitable material for allowing the decorative foldable door member  100  to be folded and unfolded between a non-installed position ( FIG. 8 ) and an interfacing position ( FIGS. 6 ,  7  and  9 ). Thus, the foldable layer  128  needs to be flexible and strength such as to fold and unfolded without damage or with reduced risks of damages. 
         [0093]    According to another embodiment, the foldable layer  128  may cover the internal interfacing surfaces  114   a ,  114   b  of the internal mounting element  112  and the external mounting elements  118   a ,  118   b . The foldable layer  128  may partially cover the internal interfacing surfaces  114   a ,  114   b  of the internal mounting element  112  and of the external mounting elements  118   a ,  118   b.    
         [0094]    According to another embodiment, the foldable layer  128  may cover the external surfaces  116 ,  124   a ,  124   b  of the internal/external mounting elements  112 ,  118   a  and  118   b . The foldable layer  128  may partially cover the external surfaces  116 ,  124   a  and  124   b  of the internal/external mounting elements  112 ,  118   a ,  118   b.    
         [0095]    According to another embodiment, the foldable layer  128  may further include at least one foldable fin (i.e., outwardly projecting portion) outwardly extending from the foldable layer  128 . Indeed, during the installation of the decorative foldable door member  100 , it will be easier with the fins or projecting portions (not shown) to control the position of the decorative foldable door member  100  between the non interlacing position and the interlacing position. 
         [0096]    According to another embodiment, the mating connector  130  formed within the external mounting elements  118   a ,  118   b  (i.e., at their respective ends) when in the interfacing position, may further define a compartment  144  for receiving a liquid composition (i.e. glue or adhesive composition) for facilitating the installation of the decorative foldable door member  100  and the connection with the corresponding mating connectors  134  of the other door members  135 . 
         [0097]    It is to be noted that in embodiments, the foldable layer  128  may be weakened at places corresponding to the longitudinal ends  120 ,  122  of the internal mounting element  112 . In this scenario, the decorative foldable door member  100  may fold and unfold to adopt any position between the non-interfacing position and the interfacing position. 
         [0098]    According to another embodiment and referring now to  FIGS. 10-13  and  14 A- 14 D, there is shown a foldable door frame assembly  200  to be interfacing with an opening defined by a wall. 
         [0099]    In  FIGS. 14A-14D , there is shown a perspective view of a wall  201  defining a door opening  202 . It is to be mentioned that the door opening  202  may also be understood to be a window opening, a garage opening and any other suitable opening for receiving a foldable door frame assembly  200  as described below. The opening  202  may be defined in the wall  201  by peripheral external surfaces  203   a - 203   f  and internal surfaces  205   a - 205   c  which have lateral lengths (i.e., the thickness of the wall  201  or of the structure).  FIGS. 14A-14D  show that edges are defined at meeting points of the peripheral external surfaces  203   a - 203   f  and the internal surfaces  205   a - 205   c.    
         [0100]    Referring now to  FIGS. 10-13 , there is shown the foldable door frame assembly  200 . The foldable door frame assembly  200  is to be interfacing with the peripheral external surfaces  203   a - 203   f  and the internal surfaces  205   a - 205   c  of the wall  201  defining the door opening  202 . The foldable door frame assembly  10  includes at least three decorative foldable door frames  211   a ,  211   b ,  211   c . Each one of the decorative foldable door frames  211   a ,  211   b ,  211   c  extends from another one of the decorative foldable door frames  211   a ,  211   b ,  211   c . The decorative foldable door assembly  211   a  includes internal mounting elements  212   a ,  212   b . Each one of the internal mounting elements  212   a ,  212   b  defines internal mounting surface  218   a ,  218   b  to be interfacing with the internal surface  205   a  and external surfaces  203   a ,  203   b . The decorative foldable door frame  211   a  further includes external mounting elements  236   a ,  236   b , where each one of the external mounting elements  236   a ,  236   b  is adjacent to longitudinal sides  242 ,  244  of the internal mounting elements  212   a ,  212   b.    
         [0101]    The external mounting elements  236   a ,  236   b  include or define internal mounting surfaces  254   a ,  254   b  which can interface with the peripheral external surfaces  203   a ,  203   b  respectively and external surfaces  259   a ,  259   b.    
         [0102]    Additionally, the decorative foldable door frame  211   a  includes foldable layers  230   a ,  230   b . The foldable layers  230   a  covers or layers the external surface  259   a  of the external mounting element  236   a  and the external surface  224   a  of the internal mounting element  212   a , totally, or partially. On the other hand, the foldable layer  230   b  covers or layers the external surface  259   b  of the external mounting element  236   b  and the external surface  224   b  of the internal mounting element  212   b , totally, or partially. 
         [0103]    The foldable layers  230   a ,  230   b  totally covers the external surfaces  224   a ,  224   b ,  259   a ,  259   b  of the internal mounting elements  212   a ,  212   b  and the adjacent external mounting elements  236   a ,  236   b.    
         [0104]    According to an embodiment, the foldable layers  230   a ,  230   b  may be integrally formed for allowing the decorative foldable door frame  211   a  to fold and unfold to adopt any positions between a non installed position ( FIGS. 10 ,  11 ,  14 A and  14 B) and an interfacing position ( FIGS. 12 ,  13 ,  14 C and  14 D). 
         [0105]    The internal mounting elements  212   a ,  212   b  each defines respective longitudinal opposed ends  260   a ,  260   b ,  262   a ,  262   b .

However, it is to be noted that the internal mounting elements  212   a ,  212   b  may be integrally formed such that a decorative foldable door frame  211   a  may include only one internal mounting element and adjacent external mounting elements  236   a ,  236   b  without any mating connectors on the internal mounting element. 
         [0106]    Furthermore, the internal mounting element  212   a  defines a longitudinal edge  284   a  as the internal mounting element  212   b  defines a longitudinal edge  284   b . Also, the external mounting elements  236   a ,  236   b  each define a corresponding edge  286   a ,  286   b  for interfacing with the longitudinal edges  284   a ,  284   b  of the internal mounting elements  212   a ,  212   b  when the decorative foldable door frame  211   a  adopts an interfacing position ( FIGS. 12 ,  13 ,  14 C and  14 D). 
         [0107]    The longitudinal edge  284   a  of the internal mounting element  212   a  and the longitudinal edge  284   b  of the internal mounting element  212   b  define a 90° longitudinal edge. Moreover, the corresponding edge  286   a  of the external mounting element  236   a  and the corresponding edge  286   b  of the external mounting element  236   b  define a corresponding 90° longitudinal edge for interfacing with the longitudinal edges  284   a ,  284   b  of the internal mounting elements  212   a ,  212   b  when adopting the interfacing position ( FIGS. 12 ,  13 ,  14 C and  14 D). 
         [0108]    Similarly, the decorative foldable door frame  211   b  includes internal mounting elements  214   a ,  214   b . Each one of the internal mounting elements  214   a ,  214   b  defines internal mounting surface  220   a ,  220   b  to be interfacing with the internal surface  205   b  and external surfaces  203   c ,  203   d . The decorative foldable door frame  211   b  further includes external mounting elements  238   a ,  238   b , where each one of the external mounting elements  238   a ,  238   b  is adjacent to longitudinal sides  246 ,  248  of the internal mounting elements  214   a ,  214   b.

Moreover, the corresponding edge  294   a  of the external mounting element  240   a  and the corresponding edge  294   b  of the external mounting element  240   b  define a corresponding 90° longitudinal edge for interfacing with the longitudinal edges  292   a ,  292   b  of the internal mounting elements  216   a ,  216   b  when adopting the interfacing position ( FIGS. 12 ,  13 ,  14 C and  14 D). 
         [0124]    Also, the internal mounting elements  212   a ,  212   b ,  214   a ,  214   b ,  216   a ,  216   b  and/or the external mounting elements  236   a ,  236   b ,  238   a ,  238   b ,  240   a ,  240   b  may be fixed to the internal surfaces  205   a ,  205   b  and/or  205   c  or the peripheral external surfaces  203   a - f  of wall  201  defining the door opening  202  using, without limitation, screws, nails, glue, dove tail elements and any other suitable fastener for fixing the internal mounting elements  212   a ,  212   b ,  214   a ,  214   b ,  216   a ,  216   b  and/or the external mounting elements  236   a ,  236   b ,  238   a ,  238   b ,  240   a ,  240   b  to the internal surfaces  205   a ,  205   b  and/or  205   c  or to the peripheral external surfaces  203   a - f . More preferably, the internal mounting elements  212   a ,  212   b ,  214   a ,  214   b ,  216   a ,  216   b  are interfacing with the internal surface  205   a ,  205   b  and/or  205   c  and the external mounting elements  236   a ,  236   b ,  238   a ,  238   b ,  240   a ,  240   b  are fixed to the peripheral external surfaces  203   a - f.    
         [0125]    According to an embodiment, the internal mounting elements  212   a ,  212   b ,  214   a ,  214   b ,  216   a ,  216   b  and the external mounting elements  236   a ,  236   b ,  238   a ,  238   b ,  240   a ,  240   b  may include, without limitation, a medium-density fiberboard material (i.e., MDF), a low-density fiberboard material (i.e., LDF), a high-density fiberboard material (i.e., HDF), a particle board, a wood material, a metallic material, a polymeric material, any combinations, and any other suitable material for use of the decorative foldable door frames  211   a ,  211   b ,  211   c  in indoor conditions or in outdoor conditions (or in both indoor and outdoor conditions). 
         [0126]    According to another embodiment, the foldable layers  230   a ,  230   b ,  232   a ,  232   b ,  234   a ,  234   b  may include, without limitation, a thermoplastic material, a plastic material, a polymeric material, a metallic material, a linerboard material, any combinations, and any suitable material for allowing the decorative foldable door assembly  200  to be folded and unfolded between a non-installed position and an interfacing position. Thus, the foldable layers  230   a ,  230   b ,  232   a ,  232   b ,  234   a ,  234   b  need to be flexible and strength such as to fold and unfolded without damage. 
         [0127]    The foldable layers  230   a ,  230   b ,  232   a ,  232   b ,  234   a ,  234   b  may cover the internal mounting surfaces  218   a ,  218   b ,  220   a ,  220   b ,  222   a ,  222   b  of the internal mounting elements  212   a ,  212   b ,  214   a ,  214   b ,  216   a ,  216   b  and of the external mounting elements  236   a ,  236   b ,  238   a ,  238   b ,  240   a ,  240   b . However, it is to be noted that the foldable layers  230   a ,  230   b ,  232   a ,  232   b ,  234   a ,  234   b  may partially or totally covers the internal mounting surfaces  218   a ,  218   b ,  220   a ,  220   b ,  222   a ,  222   b  of the internal mounting elements  212   a ,  212   b ,  214   a ,  214   b ,  216   a ,  216   b  and of the external mounting elements  236   a ,  236   b ,  238   a ,  238   b ,  240   a ,  240   b.    
         [0128]    According to another embodiment, the foldable layers  230   a ,  230   b ,  232   a ,  232   b ,  234   a ,  234   b  may also cover the external surfaces  224   a ,  224   b ,  226   a ,  226   b ,  228   a ,  228   b ,  259   a - f  of the internal mounting elements  212   a ,  212   b ,  214   a ,  214   b ,  216   a ,  216   b  and of the external mounting elements  236   a ,  236   b ,  238   a ,  238   b ,  240   a ,  240   b . It is to be noted that in both cases, the foldable layers  230   a ,  230   b ,  232   a ,  232   b ,  234   a ,  234   b  may be weakened at longitudinal lines (not shown) corresponding to the longitudinal sides respectively between the internal mounting elements  212   a ,  212   b ,  214   a ,  214   b ,  216   a ,  216   b  and the external mounting elements  236   a ,  236   b ,  238   a ,  238   b ,  240   a ,  240   b . In this case, the decorative foldable door frames  211   a - c  may fold and unfold to adopt any position between the non-installed position and the interlacing position. 
         [0129]    In use and referring now to  FIGS. 14A-14D , the foldable door assembly  200  is in its folded position in  FIG. 14A . In  FIG. 14B , external mounting elements  236   a ,  238   a  and  240   a  adopt unfolded positions and a portion of the foldable door frame assembly  200  is introduced within the opening  202  defined by the wall  201 . In  FIG. 14C , the external mounting elements  236   b ,  238   b  and  240   c  also adopt the unfolded positions. Then, the external mounting elements  236   a ,  236   b ,  238   a ,  238   b ,  240   a  and  240   b  can now interface with the peripheral external surfaces  203   a - 203   f  of the wall  201 .  FIG. 14D  shows that the foldable door frame assembly  200  is operative since a door can then be opened and closed. 
         [0130]    According to another embodiment and referring now to  FIGS. 15A-15D  and  16 , there is shown another embodiment of a decorative foldable frame  300 .  FIG. 15A  is a side elevation view of a decorative foldable door frame  300  in a non-installed position.  FIG. 15B  is another side elevation view of the decorative foldable door frame  300  of  FIG. 15A  in a non-installed position.  FIG. 15C  is another side elevation view of the decorative foldable door frame  300  of  FIG. 15A  in a non-installed position.  FIG. 15D  is another side elevation view of the decorative foldable door frame  300  of  FIG. 15A  in a non-installed position, where the mating connectors are releasably connected and  FIG. 16  is a side elevation view of the decorative foldable door frame  300  of  FIGS. 15A-15D  in an installed position in accordance with another embodiment. 
         [0131]    The decorative foldable door frame  300  is to be interfacing with the peripheral external surfaces  14   a ,  14   b  and the internal surface  12  of the wall  9  defining the door opening  11  ( FIG. 1 ). The decorative foldable door frame  300  includes internal mounting elements  316   a ,  316   b . Each one of the internal mounting elements  316   a ,  316   b  defines an internal mounting surface  318   a ,  318   b  to be interlacing with the internal surface  12  and external surfaces  320   a ,  320   b . The decorative foldable door frame  300  further includes external mounting elements  324   a ,  324   b , where each one of the external mounting elements  324   a ,  324   b  is adjacent to longitudinal sides  326 ,  327  of the internal mounting elements  316   a ,  316   b.    
         [0132]    The external mounting elements  324   a ,  324   b  include or define internal mounting surfaces  328   a ,  328   b  which can fixedly interface with the peripheral external surfaces  14   a ,  14   b  respectively and external surfaces  330   a ,  330   b.    
         [0133]    Additionally, the decorative foldable door frame  300  includes foldable layers  322   a ,  322   b . As shown in  FIGS. 15A-16 , the foldable layer  322   a  covers or layers the external surface  330   a  of the external mounting element  324   a  and the external surface  320   a  of the internal mounting element  316   a , totally, or partially. On the other hand, the foldable layer  322   b  covers or layers the external surface  330   b  of the external mounting element  324   b  and the external surface  320   b  of the internal mounting element  316   b , totally, or partially. 
         [0134]    Still referring to  FIGS. 15A-16 , the foldable layers  322   a ,  322   b  totally covers the external surfaces  320   a ,  320   b ,  330   a ,  330   b  of the internal mounting elements  316   a ,  316   b  and the adjacent external mounting elements  324   a ,  324   b.    
         [0135]    According to an embodiment, the foldable layers  322   a ,  322   b  may be integrally formed for allowing the decorative foldable door frame  300  to fold and unfold to adopt any positions between a non-installed position ( FIGS. 15A ,  15 B,  15 C and  15 D) and an interfacing position ( FIG. 16 ). 
         [0136]    Still referring to  FIGS. 15A-16 , there is shown the internal mounting elements  316   a  with the external mounting element  324   a  and the internal mounting elements  316   b  with the external mounting element  324   b . The internal mounting elements  316   a ,  316   b  each defines respective longitudinal opposed ends  336   a ,  337   a ,  336   b ,  337   b . As shown, the end  337   a  of the internal mounting element  316   a  includes a mating connector  338  which can releasably connect with a corresponding mating connector  340  on the end  336   b  of the internal mounting element  316   b  ( FIG. 16 ). However, it is to be noted that the internal mounting elements  316   a ,  316   b  may be integrally formed such that a decorative foldable door frame  300  may include only one internal mounting element and adjacent external mounting elements  324   a ,  324   b  without any mating connectors of the internal mounting element. 
         [0137]    Furthermore, the internal mounting element  316   a  defines a longitudinal edge  342  as the internal mounting element  316   b  defines a longitudinal edge  346  ( FIGS. 15B ,  15 C and  15 D). Also, the external mounting elements  324   a ,  324   b  each define a corresponding edge  344 ,  348  ( FIGS. 15B ,  15 C and  15 D) for interfacing with the longitudinal edges  342 ,  346  of the internal mounting elements  316   a ,  316   b  when the decorative foldable door frame  300  adopts an interfacing position ( FIGS. 15A and 16 ). The longitudinal edge  342  of the internal mounting element  316   a  and the longitudinal edge  346  of the internal mounting element  316   b  define a flat longitudinal edge. Moreover, the corresponding edge  344  of the external mounting element  324   a  and the corresponding edge  348  of the external mounting element  324   b  define a corresponding flat longitudinal edge for interfacing with the flat longitudinal edges  342 ,  346  of the internal mounting elements  316   a ,  316   b  when adopting the interfacing position ( FIGS. 15A and 16 ). It is to be noted that the external mounting elements  324   a ,  324   b  may fold and unfolded between 0° and 90° from the internal mounting elements  316   a ,  316   b  respectively. A shown in  FIG. 15A , the flat longitudinal edges  342 ,  346  interface the flat corresponding edges  344 ,  348  of the external mounting elements  324   a ,  324   b  for allowing the external mounting elements  324   a ,  324   b  to be in the interfacing position for interfacing with the peripheral external surfaces  14   a ,  14   b  ( FIG. 1 ). However, in  FIG. 15B , there is shown that the flat longitudinal edges  342 ,  346  do not interface the flat corresponding edges  344 ,  348  of the external mounting elements  324   a ,  324   b  for allowing the external mounting elements  324   a ,  324   b  to be in the non-installed position. Then, there is shown in  FIG. 15C  that the flat longitudinal edges  342 ,  346  do not interface the flat corresponding edges  344 ,  348  of the external mounting elements  324   a ,  324   b  for allowing the external mounting elements  324   a ,  324   b  to be in the interfacing position for interfacing with the peripheral external surfaces  14   a ,  14   b  ( FIG. 1 ). In  FIG. 15C , the external mounting elements  324   a ,  324   b  are at angle of about 45° from the respective internal mounting elements  316   a ,  316   b . In  FIG. 15D , there is shown that the flat longitudinal edges  342 ,  346  do not interface the flat corresponding edges  344 ,  348  of the external mounting elements  324   a ,  324   b  for allowing the external mounting elements  324   a ,  324   b  to be in the non-installed position. However, in  FIG. 15D , the mating connector  338  is releasably connected with the corresponding mating connector  340 . 
         [0138]    Furthermore, the internal mounting elements  316   a ,  316   b  interact with the external mounting elements  324   a ,  324   b  for creating a 90° angle ( FIG. 16 ). As shown on  FIG. 16 , the flat edges  342 ,  346  and the flat edges  344 ,  348  interact and interface to position the decorative foldable door frame  300  in its interfacing position (i.e., the internal mounting elements  316   a ,  316   b  and the external mounting elements  324   a ,  324   b  are at a 90° angle). 
         [0139]    Also, the internal mounting elements  316   a ,  316   b  and/or the external mounting elements  324   a ,  324   b  may be fixed to the internal surface  12  ( FIG. 1 ) or the peripheral external surfaces  14   a ,  14   b  ( FIG. 1 ) of wall  9  defining the door opening  11  using, without limitation, screws, nails, glue, dove tail elements and any other suitable fastener for fixing the internal mounting elements  316   a ,  316   b  and/or the external mounting elements  324   a ,  324   b  to the internal surface  12  or to the peripheral external surfaces  14   a ,  14   b . More preferably, the internal mounting elements  316   a ,  316   b  are interfacing with the internal surface  12  and the external mounting elements  324   a ,  324   b  are fixed to the peripheral external surfaces  14   a ,  14   b.    
         [0140]    According to an embodiment, the internal mounting elements  316   a ,  316   b  and the external mounting elements  324   a ,  324   b  may include, without limitation, a medium-density fiberboard material (i.e., MDF), a low-density fiberboard material (i.e., LDF), a high-density fiberboard material (i.e., HDF), a particle board, a wood material, a metallic material, a polymeric material, any combinations, and any other suitable material for use of the decorative foldable door frame  300  in indoor conditions or in outdoor conditions (or in both indoor and outdoor conditions). 
         [0141]    According to another embodiment, the foldable layers  322   a ,  322   b  may include, without limitation, a thermoplastic material, a plastic material, a polymeric material, a metallic material, a linerboard material, any combinations, and any suitable material for allowing the decorative foldable door frame  300  to be folded and unfolded between a non-installed position ( FIGS. 15A-15D ) and an interfacing position ( FIG. 16 ). Thus, the foldable layers  322   a ,  322   b  need to be flexible and strength such as to fold and unfolded without damage or with reduced risks of damages. 
         [0142]    As shown in  FIGS. 15A-16 , the foldable layers  322   a ,  322   b  may cover the internal mounting surfaces  318   a ,  328   a ,  318   b ,  328   b  of the internal mounting elements  316   a ,  316   b  and of the external mounting elements  324   a ,  324   b . However, it is to be noted that the foldable layers  322   a ,  322   b  may partially or totally covers the internal mounting surfaces  318   a ,  328   a ,  318   b ,  328   b  of the internal mounting elements  316   a ,  316   b  and of the external mounting elements  324   a ,  324   b.    
         [0143]    According to another embodiment, the foldable layers  322   a ,  322   b  may also cover the external surfaces  320   a ,  330   a ,  320   b ,  330   b  of the internal mounting elements  316   a ,  316   b  and of the external mounting elements  324   a ,  324   b . It is to be noted that in both cases, the foldable layers  322   a ,  322   b  may be weakened at longitudinal lines (not shown) between the internal mounting element  316   a  and the external mounting element  324   a  and the internal mounting element  316   b  and the external mounting element  324   b . In this case, the decorative foldable door frame  300  may fold and unfold to adopt any position between the non installed position ( FIGS. 15A-15D ) and the interfacing position ( FIG. 16 ). 
         [0144]    According to another embodiment, the foldable layers  322   a ,  322   b  may partially or totally cover the external surfaces  320   a ,  330   a ,  320   b ,  330   b  of the internal mounting elements  316   a ,  316   b  and of the external mounting elements  324   a ,  324   b.    
         [0145]    In the scenario where the foldable layers  322   a ,  322   b  cover the internal mounting surfaces  318   a ,  328   a ,  318   b ,  328   b  of the internal mounting elements  316   a ,  316   b  and the external mounting elements  324   a ,  324   b , the foldable layers  322   a ,  322   b  may further include at least one foldable fin (i.e., or projecting portion, not shown) outwardly extending from the foldable layers  322   a ,  322   b.    
         [0146]    It is to be notated that, the internal mounting element  316   a  adjacent with the external mounting element  324   a  via the foldable layer  322   a  and the internal mounting element  316   b  adjacent with the external mounting element  324   b  via the foldable layer  322   b  may come into a kit for allowing a user to releasably connect them, via the mating connectors  338  and  340  of the internal mounting elements  316   a ,  316   b.    
         [0147]    It is to be noted that the ends of the external mounting elements  324   a ,  324   b  opposite the ends  337   a ,  336   b  with the mating connectors each include a mating connector  400 ,  401  for releasably connecting with a corresponding mating connector (not shown) of a decorative element (i.e., a decorative molding). 
         [0148]    While preferred embodiments have been described above and illustrated in the accompanying drawings, it will be evident to those skilled in the art that modifications may be made without departing from this disclosure. Such modifications are considered as possible variants comprised in the scope of the disclosure.
