Title: System and method for removably connecting trim to a wall or ceiling or both

Description:
RELATED APPLICATION 
     This application is a national stage of International Application No. PCT/US2008/011475 filed Oct. 4, 2008, which is hereby incorporated herein by reference. 
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to devices and methods for removably connecting trim to a wall or ceiling or both. 
     2. Description of Related Art 
     There are two main purposes of trim carpentry. The first is to cover up all the rough edges left over from the construction of a house or other building. The other main purpose is to add a decorative and finished look to the walls, doors and windows of the house or other building. Thus, trim carpentry is an important part of the presentation of a home or building. 
     Installing trim is a difficult and demanding job. Typically, individual pieces of trim are cut and nailed into place more or less permanently affixing the trim to a wall or ceiling or around a door or window. The holes produced in the trim by driving nails through the trim require puttying to fill the holes and sanding to prepare the trim for painting, staining or other coating. This difficult process is made more difficult by the fact that walls, floors, ceilings and door and window frames are seldom flat, straight and square. 
     Further, the flatness, straightness and squareness of these items often changes over time as the building shifts or settles. In addition, it is often desirable to remove or replace pieces of trim to give a new appearance or to replace damaged or worn pieces. Also, it is often desirable to have access to a wall or ceiling behind a piece of trim in order to access the wall or ceiling or a cavity behind the wall or ceiling or to run wires or cabling behind the trim. As a result, it is often necessary or desirable or both to remove pieces of trim previously permanently affixed. At best this usually results in a difficult process especially when trying to preserve the piece of trim to be removed. Often the trim piece is damaged in the removal process. If a trim piece is reused, the original nails have to be cut off or removed or both and the existing nail holes or new holes created by the new nails or both have to be filled with putty and sanded. 
     In view of the foregoing, it is desirable to be able to easily remove and reinstall trim. 
     SUMMARY OF THE INVENTION 
     A bracket system is disclosed for allowing conventional trim to be removably connected to a wall or ceiling or both. The bracket system includes a wall bracket that is attached to the wall or ceiling or both and a trim bracket that is attached to conventional trim. The wall bracket and trim bracket interlock with each other and are held securely together by a removable mating contact. The wall bracket and trim bracket can be pulled apart and pushed together to allow for removal and reinstallation of trim without mechanical modification or destruction of any components. 
     A preferred embodiment of the bracket system includes an insert bracket that is placed inside and concealed within the wall bracket. The insert bracket helps to retain cabling within the wall bracket when the trim bracket is removed or to keep cabling running along the bracket system separated. 
     Various objects and advantages of the invention will be clear in view of the following description to the invention including the associated drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     A concealed bracket system is disclosed generally referred to by the reference number  10 . The bracket system  10  is used to attach conventional trim to a wall  12  or ceiling  14 . The bracket system  10  has two primary parts, a wall bracket  16  that attaches to the wall  12  or ceiling  14  or both with wall bracket fasteners  18 . The second part, a trim bracket  20 , attaches to conventional trim  22  with trim bracket fasteners  24 . The wall bracket  16  and trim bracket  20  interlock with each other and are held together in mating contact. The wall bracket  16  and trim bracket  20  can be pulled apart or pushed together to allow for removal and reinstallation of trim  22  without mechanical modification or destruction of any components. 
     The wall bracket  16  is preferably concealed and attached to a wall  12  or ceiling  14  or both constructed of wood studs, metal studs, gypsum board, plaster, stucco, wood paneling or any other type of wall construction material. The wall bracket  16  may be recessed from or flush with the face of the finished wall  12  or ceiling  14  or may project out from the finished wall  12  or ceiling  14  but still be concealed by the trim  22  as in the case of installation in a corner where crown molding  26  would bridge across the two walls  12  or wall  12  and ceiling  14  surfaces to fully conceal the wall bracket  16 . 
     As can be seen in  FIGS. 2 and 6 , the wall bracket  16  in a preferred embodiment includes a backplate  28  and a pair of opposed wall bracket retaining fingers  30 . The backplate  28  in a preferred embodiment is essentially a long, flat, planar piece that is attached to a wall  12  or ceiling  14  by wall bracket fasteners  18 . 
     In a preferred embodiment of the wall bracket  16 , the backplate  28  has no preformed holes extending through the backplate  28  to receive wall bracket fasteners  18  that pass through the preformed holes into a wall  12  or ceiling  14  to hold the backplate  28  in firm contact with the wall  12  or ceiling  14 . Instead, the backplate  28  in this embodiment is made of a material such as a thin metal or other similar material that can be easily penetrated by standard screws or nails without requiring that there be a preformed hole or that a pilot hole be drilled. In this embodiment, wall bracket fasteners  18  are used but, because the person fastening the backplate  28  to a wall usually has a solid wall or ceiling to push against when screwing in the wall bracket fastener  18 , there is no need to precisely locate holes for receiving the wall bracket fasteners  18 . 
     In another embodiment of the wall bracket  16 , the backplate  28  has one or more backplate holes  32  extending through the backplate  28  to receive wall bracket fasteners  18  that pass through the backplate holes  32  into a wall  12  or ceiling  14  to hold the backplate  28  in firm contact with the wall  12  or ceiling  14 . The backplate holes  32  in this embodiment would typically be at predetermined intervals such as a  16 ″ separation corresponding to the  16 ″ center to center span of standard wall studs or floor joists to match up with normal wall stud or floor joist spacing in typical construction. Of course, if the wall stud or floor joist spacing varied from the spacing of the backplate holes  32  based on a standard spacing dimension, which it often does, the preformed backplate holes  32  wouldn&#39;t be aligned with the existing wall studs or floor joists. Consequently, this embodiment of the backplate  28  will have particular utility to those situations where the wall stud or floor joist spacing is typical or where the wall stud or floor joist spacing is known in advance and, in either case, where the dimensions and relative location of the backplate  28  with respect to a wall  12  or ceiling  14  is known in advance. 
     Where backplate holes  32  are used, the backplate holes  32  can be vertically slotted type holes, if desired, that would allow easy vertical adjustment of the wall bracket  16  without moving the existing wall bracket fasteners  18 . The wall bracket  16  may also be manufactured with backplate holes  32  to accommodate passage of cabling from a wall cavity  34  to within the cavity  36  of the wall bracket  16 . The backplate holes  32  may also be of a common shape that would allow easy attachment of readily available conduit that may be installed within the wall cavity  34  or a ceiling cavity  38 . Of course, the backplate  28  may be made of a material such as a thin metal or other similar material that can be easily penetrated by standard screws and also have preformed backplate holes  32 . 
     The wall bracket  16  may be flexible to allow the wall bracket  16  to follow and conform to the shape of a curved wall  12  or ceiling  14  to which it is attached. The wall bracket  16  may itself be made of a flexible material ( FIG. 7 ) or may be segmented ( FIG. 8 ) to allow the wall bracket  16  to be flexible. In the embodiment of the wall bracket  16  shown in  FIG. 8 , the backplate  28  is comprised of two or more backplate segments  28 ′ so that each backplate segment  28 ′ is connected to its adjacent backplate segment  28 ′ through a hinge  52  (e.g., a living hinge) that allows each backplate segment  28 ′ to pivot around the hinge  52  to follow the curvature of the wall. Each backplate segment  28 ′ can be either rigid or flexible as desired. Each backplate segment  28 ′ also has a pair of opposed wall bracket retaining fingers  30  extending away from it as described herein. Each pair of opposed wall bracket retaining fingers  30  is sized to have a width corresponding roughly with the width of each backplate segment  28 ′. It is also within the scope of the invention for a backplate  28  to have material removed to make the backplate  28  more flexible or to reduce the cost or weight of the material of the backplate  28 . 
     The wall bracket retaining fingers  30  are located on opposite sides of the backplate  28  and extend away from the backplate  28  on the same side of the backplate  28 . The wall bracket retaining fingers  30  each have a retaining fingers ultimate end  40  that curves inwardly toward each other forming a retaining finger lip  42 . The height of the wall bracket retaining fingers  30  is such that a trim bracket  20  will be retained against the backplate  28  by contact between the wall bracket retaining fingers  30 , and more particularly the lips  42 , and the trim bracket  20  as will be described hereafter. In a particularly useful embodiment of the wall bracket  16 , the wall bracket retaining fingers  30  have a height of slightly less than the thickness of a gypsum wall covering  44  or other wall covering material as shown in  FIG. 9  so that when a trim bracket  20  is mated with the wall bracket  16 , a piece of trim  22  attached to the trim bracket  20  will be moved into flush contact with the wall covering  44  and not held out from the finished wall surface by the wall bracket  16 . 
     The length of a wall bracket  16  is defined as the distance parallel to the wall  12  or ceiling  14  that the bracket system  10  is attached to. For example, the length of a wall bracket  16  is represented by the horizontal length where the bracket system  10  is used to attach a piece of trim  22  to a wall  12 . The length of the wall bracket  16  is preferably continuous between attachment points to the wall  12  or ceiling  14  with a length similar to the attaching trim  22 . 
     Alternately, the length of the wall bracket  16  can be relatively shorter so that individual segments or clips are produced as described above that are placed at desired attachment points to the wall  12  or ceiling  14  spaced along the length of the attaching trim  22 . As a further alternative, a combination of relatively long, continuous wall brackets  16  may be used in conjunction with one or more relatively short “clip” versions of the wall bracket  16 . In any embodiment of the wall bracket  16 , the length of the wall bracket  16  does not need to match the length of the attaching trim  22  as the wall bracket  16  or wall brackets  16  are concealed. Consequently, the length of the one of more pieces of wall bracket  16  only needs to be a length that provides an appropriate and desired attachment strength and stability to the attaching trim  22 . 
     Although the backplate  28  in a preferred embodiment is essentially long, flat and planar, as described above the backplate  28  may also be short or made up of one or more shorter sections ( FIG. 6 ). Further, the backplate  28  need not be flat. Instead, any shape may be used for the backplate  28  so long as the backplate  28  is capable of being rigidly attached to a wall through wall bracket fasteners  18 . For example, the backplate  28  may be substantially planar but have a channel formed that extends along at least a portion of the backplate  28  to allow the backplate  28  to be placed over, for example, wiring or conduits. As mentioned above, portions of the backplate  28  may be removed to reduce the weight or cost of the material of the backplate  28 . In addition, portions of the backplate  28  may be removed to allow air to circulate through or around the backplate  28 . Further, backplate  28  may be curved in a vertical direction to allow the backplate  28  to be secured to a correspondingly shaped wall  12  or ceiling  14 . 
     As can also be seen in  FIGS. 2 ,  6  and  7 , trim bracket  20  preferably includes at least one trim clip  46  each having a trim plate  48  and pair of opposed trim bracket retention edges  50  located on opposite edges of the trim plate  48 . The preferred embodiment of the bracket system  10  includes the trim bracket  20  being made up of at least two individual trim clips  46  ( FIG. 6 ). However, one embodiment of the bracket system  10  includes a single trim clip  46  where the trim plate  48  is essentially a long flat piece with a pair of opposed trim bracket retention edges  50  extending along edges of the trim plate  48  ( FIG. 7 ). In another embodiment, the trim bracket  20  is a single trim clip  46  such as that shown in  FIG. 6  with the trim clip  46  having a relatively short length. Whether there are several individual trim clips  46  or a single trim clip  46 , the trim clip  46  or trim clips  46  are attached to a piece of trim  22  by trim bracket fasteners  24 . 
     The trim plate  48  also preferably has at least one but preferably several trim plate holes  54  extending through the trim plate  48  to receive trim bracket fasteners  24  that pass through the trim plate holes  54  into the trim  22  to hold the trim bracket  20  in firm contact with the trim  22 . The trim plate holes  54  can be vertically slotted type holes, if desired, that allow easy vertical adjustment of the trim  22  with respect to the trim bracket  20  without moving the existing trim bracket fasteners  24 . 
     As mentioned above, the wall bracket  16  may be flexible or segmented to allow the wall bracket  16  to follow and conform to the shape of a curved wall  12  or ceiling  14  to which it is attached. The trim bracket  20  also needs to be flexible or segmented to mate with the wall bracket  16  where the wall bracket  16  is flexible or segmented and attached to a curved wall  12  or ceiling  14 . The trim bracket  20  may itself be made of a flexible material ( FIG. 7 ) or may be segmented ( FIG. 8 ) to allow the trim bracket  20  to be flexible. In the embodiment of the trim bracket  20  shown in  FIG. 7 , the trim plate  48  is comprised of a single trim plate  48  made of a flexible material. Alternately, the trim plate  48  made be made of two or more trim clips  46  as shown in  FIG. 6  or the trim plate  48  may be segmented ( FIG. 8 ) similarly to how the backplate  28  is segmented into backplate segments  28 ′ described above. Again, each trim plate segment  20 ′ can be either rigid or flexible as desired and each trim plate segment  20 ′ also has an associated trim clip  46  having a pair of opposed trim bracket retention edges  50  extending away from it as described herein. Each pair of opposed trim bracket retention edges  50  is sized to have a width corresponding roughly with the width of each trim plate segment. Of course, to use a curved or flexible wall bracket  16  and corresponding trim bracket  20 , the trim  22  must also be curved or flexible. Similarly, as described in connection with the description of the backplate  28 , it is also within the scope of the invention for a trim plate  48  to have material removed to make the trim plate  48  more flexible or to reduce the cost or weight of the material of the trim plate  48 . Of course, a flexible or segmented wall bracket  16  could be used with a non-flexible or non-segmented trim bracket  20 , or vice versa, when used on a flat wall  12  or ceiling  14 . 
     The trim bracket retention edges  50  are located on opposite sides of the trim plate  48  of the trim clip  46  and extend away from the trim plate  48  in the same direction. The trim bracket retention edges  50  have a trim bracket most outer edge  56  and a trim bracket ultimate end  58  that curves inwardly forming a trim bracket lip  60 . The height of the trim bracket retention edges  50  are such that, when coupled with the wall bracket retaining fingers  30  of the wall bracket  16 , contact between the wall bracket retaining fingers  30  and the trim bracket retention edges  50  holds the trim bracket retention edges  50  in firm contact against the backplate  28  as shown in  FIG. 9 . As a result, the height of both the wall bracket  16  and trim bracket  20  are similar for the same bracket system  10  to allow for interlocking except that the height of the trim bracket  20  is slightly less than the height of the wall bracket  16  to allow the trim bracket  20  and attached trim  22  to be pulled against the face of the finished surface of the wall  12  or the wall bracket  16  and not held out from the finished surface of the wall  12  or wall bracket  16 . 
     The maximum height of the wall bracket  16  and trim bracket  20  is determined by the height of the attaching trim  22  allowing adequate overlap of the trim  22  above or below the trim bracket  20  or both above and below the trim bracket  20  in order for the trim  22  to overlap and conceal the joint  62  between the wall bracket  16  and the adjacent finished surface of the wall  12 . The minimum height of the wall bracket  16  and trim bracket  20  is determined by the height that provides adequate stability and support of the trim  22 . 
     As described above, the trim bracket  20  may be made of a series of individual trim clips  46 , one long continuous trim clip  46  or a combination of relatively shorter and longer trim clips  46 . The length of a trim clip  46  can be continuous between attachment points to the trim  22  so that the trim clip  46  is similar in length to the attaching trim  22  or each trim bracket  46  can be a shorter individual segments placed at desired attachment points on the trim  22  spaced along the length of the attaching trim  22 . The length of the entire trim bracket  20 , whether as a continuous piece or a series of individual trim clips  46  does not need to match the length of the attaching trim  22  or wall bracket  16 . This is because the one or more trim clips  46  are concealed and consequently only need to be a length that provides an appropriate and desired attachment strength and stability to the attaching trim  22 . 
     The configuration of the retaining finger  30  and the retention edge  50  are such that both the retaining finger  30  and the retention edge  50  are able to flex as they move past initial contact with each other and to their final and locking position. This is preferably accomplished by the retention edge  50  having a configuration that allows the retention edge  50  to mate with the wall bracket retaining fingers  30  is a three step process shown in  FIGS. 3-5 . 
     The first step in the three step process, shown in  FIGS. 3 ,  6  and  7 , brings the trim bracket retention edges  50  into contact with the wall bracket retaining fingers  30 . In this configuration, the retention edge  50  near the trim bracket ultimate end  58  will be in contact with the wall bracket retaining fingers  30  near the retaining finger lip  42  but both the wall bracket retaining fingers  30  and the trim bracket retention edges  50  are in a rest or unstressed condition. 
     The second step in the three step process, shown in  FIG. 4 , moves the trim bracket  20  toward the wall bracket  16 . As the trim bracket  20  is moved toward the wall bracket  16 , the wall bracket retaining fingers  30  move slightly outwardly while the trim bracket retention edges  50  move slightly inwardly as the trim bracket most outer edge  56  moves past the retaining finger lip  42  thereby moving either the wall bracket retaining fingers  30  or the trim bracket retention edges  50  or both into a stressed or biased position. The wall bracket retaining fingers  30  and the trim bracket retention edges  50  are dimensioned to allow each to flex slightly as the trim bracket most outer edge  56  moves past the retaining finger lip  42  and then return to their rest position. 
     The third step in the three step process, shown in  FIG. 5 , is accomplished when the trim bracket most outer edge  56  has moved past the retaining finger lip  42 . In this configuration, the trim bracket most outer edge  56  moves outwardly again while the wall bracket retaining fingers  30  move inwardly again so that the retention edge  50  is locked into place between the retaining finger lip  42  and the backplate  28  by contact between the retention edge  50 , primarily around the trim bracket most outer edge  56 , and the retaining finger  30  near the retaining finger lip  42 . 
     Sometimes, instead of using the method to mate the wall bracket  16  to a trim bracket  20  as described above, it is easier to insert the bottom side of the trim clip  46  into the bottom side of the wall bracket  16  first and then push down on the trim  22  or trim bracket  20  while pushing the top side of the trim clip  46  into the top side of the wall bracket  16 . This method of mating the wall bracket  16  and trim bracket  20  often seems easier because there is no need to flex both ends of both the wall bracket  16  and trim bracket  20  at the same time while mating. In some cases the method described and shown in  FIGS. 3-5  will work better and in some cases the method just described will work better depending on the size of the pieces and the geometry or layout of the wall  12  or ceiling  14  that the bracket system  10  is used on. 
     As can be seen in  FIGS. 2-5 , the trim bracket retention edges  50  are shaped such that the trim bracket ultimate ends  58  and trim bracket most outer edges  56  of the trim bracket retention edges  50  are relatively far apart in their resting position and move farther closer to their respective partner trim bracket ultimate end  58  or trim bracket most outer edge  56  on the opposite side of the trim plate  48  as the trim bracket  20  is moved into mating contact with the wall bracket  16 . Thereafter, the trim bracket ultimate ends  58  and most outer edges  56  of the trim bracket retention edges  50  move outwardly back to their rest position. In one embodiment of the trim bracket  20 , this configuration of the trim bracket retention edges  50  is manifested in two different retention edge segments  64 ,  66  whereas in another embodiment of the trim bracket  20  this configuration is manifested in a single curved retention edge  50 . It is possible to have trim bracket retention edges  50  having more than the two retention edge segments  64 ,  66  or a continuously curved retention edge  50  that is not semicircular in shape. 
     Further, as also can be seen in  FIG. 2-5 , the wall bracket retaining fingers  30  are shaped such that opposite retaining finger retaining finger ultimate ends  40  and retaining finger lips  42  are relatively close together in their resting position and move farther from their respective partner retaining finger ultimate end  40  or retaining finger lip  42  as the trim bracket  20  is moved into mating contact with the wall bracket  16 . Thereafter, the retaining finger ultimate ends  40  and retaining finger lips  42  move back inwardly to their rest position. In one embodiment of the wall bracket  16 , this configuration of the wall bracket retaining fingers  30  is manifested in three different retaining finger segments  68 ,  70  and  72 . It is possible to have wall bracket retaining fingers  30  have two segments  68 ,  70  ( FIG. 2 ) or a single curved retaining finger  30 , semicircular or not, or a retaining finger  30  having a segment  68  with a curved retaining fingers ultimate end  40  that is semicircular or not in shape. 
     Further, the preferred embodiment described herein has both the wall bracket retaining fingers  30  and the trim bracket retention edges  50  flexing as the trim bracket  20  is moved toward and into locking contact with the wall bracket  16 . However, in other embodiments of the bracket system  10 , only the wall bracket retaining fingers  30  or the trim bracket retention edges  50 , respectively, flex as the trim bracket  20  is moved toward and into locking contact with the wall bracket  16 . 
     In use, the wall bracket  16  is attached to a wall  12  or ceiling  14  by the wall bracket fasteners  18  as shown in  FIG. 9 . A piece of trim  22  is attached to the trim bracket  20  by passing trim bracket fasteners  24  through the trim plate holes  54  so that the trim  22  is secured against the trim plate  32 . In order to ensure that the trim  22  is precisely located against the trim bracket  20  and so that once the trim bracket  20  is placed and locked in mating contact with the wall bracket  16 , the trim  22  will be precisely oriented against the wall  12  or ceiling  14 , a template or jig may be placed against the trim  22  to place the trim bracket  20  in the desired location with respect to the trim  22 . The template is preferably made of a thin material such as paper, cardboard, sheet aluminum or plastic and is either sized to indicate or has printed the location of the edges of the trim  22  and the location of the trim plate holes  54 . The template is then placed over the trim  22  and the trim bracket fasteners  24  placed through the trim plate holes  54  into the trim  22  in the desired location on the trim  22 . Where the trim bracket fasteners  24  are an adhesive, the template helps to precisely locate the trim plate  48  on the trim  22  so that the adhesive can take affect. A jig holds the trim bracket  20 , trim  22  or both so that the trim bracket  20  is precisely located on the trim  22  by the trim bracket fasteners  24  in whatever form they may take. 
     Once a piece of trim  22  is securely attached to the trim bracket  20 , the trim bracket  20  is brought into contact with the wall bracket  16  as described above in connection with step one of the three step connection process. The trim bracket retention edges  50  move in contact with the wall bracket retaining fingers  30  and past each other as described above in connection with step  1  until the trim bracket retention edges  50  move outwardly again and the wall bracket retaining fingers  30  move inwardly again so that the trim bracket  20  is held in its locked and retained position by the wall bracket retaining fingers  30  as shown in  FIG. 9 . 
     The configuration of the wall bracket retaining fingers  30  and the trim bracket retention edges  50  cooperate to securely hold the trim  22  in the desired location with respect to the wall  14  or ceiling  14 . Also, this configuration causes the wall bracket  16  and trim bracket  20  to interlock with a self adjusting depth. This means that the interaction of the wall bracket retaining fingers  30  and trim bracket retention edges  50  in step three automatically pulls the trim  22  into contact with the wall  12  or ceiling  14 . 
     It is also a part of the invention that the trim  22  be attached to the trim bracket  20  as described above and that the trim bracket  20  be mated with a wall bracket  16  but also where the trim  22  is not brought into contact with a wall  12  or ceiling  14 . In this embodiment, the wall bracket  16  and trim bracket  20  interlock with a self adjusting depth as described above so that the interaction between the wall bracket retaining fingers  30  and trim bracket retention edges  50  in step three automatically pulls the trim bracket  20  into secure contact with the wall bracket  16  and the trim is attached to the trim bracket  20 . 
     The bracket system  10  of the present invention is fully concealed by either being recessed from the face of a finished wall  12  or ceiling  14  or fully concealed behind the trim  22 . 
     A preferred embodiment of the bracket system  10  includes a third bracket, an insert bracket  74  ( FIG. 2 ). The insert bracket  74  is placed inside and concealed within the wall bracket  16  and either attached to a wall  12  or ceiling  14  with insert bracket fasteners  76  or placed inside the cavity  36  of the wall bracket  16  without direct attachment. If it is not directly attached to a wall  12  or ceiling  14 , the insert bracket  74  can be shaped so that its form holds it within the wall bracket  16  until manually deformed or squeezed so that it can be removed. 
     The insert bracket  74  can be used in conjunction with the wall bracket  16  to help retain cabling within the wall bracket  16  when the trim bracket  20  is removed. As shown in  FIG. 1 , the insert bracket  74  can be placed inside the wall bracket  16  and attached to a wall  12  or ceiling  14  with insert bracket fasteners  76  or can be placed in the wall bracket  16  against the backplate  28  between the wall bracket retaining fingers  30  without direct attachment to the wall  12  or ceiling  14 . In the latter embodiment, the insert bracket  74  is squeezed or deformed so that it passes between the fingers  30  and placed against the backplate  28 . The trim bracket  20  holds the insert bracket  74  between the backplate  28  and the trim plate  48  of the trim bracket  20  when the wall bracket  16  and trim bracket  74  are mated together as described above. 
     The form or shape of the insert bracket  74  can vary depending upon the type of cabling that is desired to be placed and held within the wall bracket  16 . However, the insert bracket  74  preferably includes a body  78  with a face plane  80 , side edges  82  and insert bracket retaining edges  84  on each side of the insert bracket  74  extending away from the side edges  82 . The body  78  is preferably an elongated body that spans substantially the entire length of its corresponding wall bracket  16 . However, the body  78  can also be one or more clips so that the body  78  is relatively short in length. In either case, the body  78  in one embodiment includes insert bracket holes  86  for passing insert bracket fasteners  76  to anchor the body  78  to a wall  12  or ceiling  14 . The insert bracket fasteners  76  may pass through the material of the backplate  28  or through backplate holes  32  in the backplate  28 . The height of the insert bracket  74  is preferably about equal to the height of the side edges  82 . This height is similar or less than the height of the wall bracket  16  that the insert bracket  74  is placed within. 
     In one embodiment, the insert bracket  74  is shaped to have one large groove  90  in the face plane  80  of the body  78  to hold cabling. In another embodiment the body  78  is shaped to have two or more small grooves  92  in face plane  80  of the body  78  to separate different cabling as may be desired if signal type cable and power type cable are run parallel and separation is required or desired to limit electrical interference or for any other reason. Either the large groove  90  or small grooves  92  may have the insert bracket holes  86  described above or the insert bracket holes  86  may be located at other locations along the body  78 . 
     The height of the side edges  82  is less than the height of either the wall bracket  16  or trim bracket  20 . This allows the trim bracket  20  to be placed over the insert bracket  74  and both the trim bracket  20  and insert bracket  74  moved past the retaining finger lip  42  so that interaction between the retaining finger lip  42  and the trim bracket retention edges  50  holds the trim bracket  20  and the insert bracket  74  securely in contact with the backplate  28  but keeps the insert bracket  74  from holding the trim bracket  20  away from the finished surface of the wall  12  or the wall bracket  16 . In a preferred embodiment, the height of the side edges  82  is such that the face plane  80  is in contact with or near contact with the trim plate  48  when the trim bracket  20  and the insert bracket  74  are securely in contact with the backplate  28 . The length of the one or more insert brackets  22  can be continuous along the length of the wall bracket  16  or can be one or more shorter individual segments placed at desired spacings along the wall bracket  16 . 
     As mentioned above, the insert bracket  74  has insert bracket retaining edges  84 . In a preferred embodiment of the insert bracket  74 , the width of the face plane  80  is such that the face plane  80  will pass between the lips  42  of the wall bracket retaining fingers  30 . In this embodiment, the insert bracket retaining edges  84  extend from the side edges  82  a distance approximately the distance that the retaining finger lip  42  extends inwardly from the wall bracket retaining fingers  30  so that the distance from one edge of a insert bracket retaining edge  84  to the other insert bracket retaining edge  84  is about the distance between the inside surfaces of the wall bracket retaining fingers  30  between the backplate  28  and the lips  42 . This allows the insert bracket  74  to be moved past the lips  42  by squeezing or deforming the insert bracket  74  and then return to its rest configuration to be retained between the wall bracket retaining fingers  30  by frictional forces until either the insert bracket  74  is secured against a wall  12  or ceiling  14  by insert bracket fasteners  76  or until the trim bracket  20  is “snapped” into secure and locking contact with the wall bracket  16  as described above. 
     In a different embodiment of the insert bracket  74  shown in  FIG. 2 , the insert bracket retaining edges  84  may also be formed in the mirror image shape of the trim bracket retention edges  50  described above. In this embodiment, the insert bracket retaining edges  84  are moved past the retaining finger lip  42  of the wall bracket retaining fingers  30  and prevented from moving away from the wall bracket  16  by the interaction between the insert bracket retaining edges  84  and the wall bracket retaining fingers  30 . In this embodiment, the insert bracket retaining edges  84  include a insert bracket retaining finger  94  having an insert bracket ultimate end  96  and a insert bracket most outer edge  98 . The insert bracket retaining finger  94  extends away from the insert bracket outer edge  100  in the direction of the face plane  80  so that the insert bracket ultimate end  96  is displaced from the retention edge  84 . The insert bracket most outer edge  98  is on the outside of the insert bracket retaining finger  94  so that opposed insert bracket most outer edges  98  are slightly farther apart in their resting configuration than are the insert bracket outer edge  100  or the other parts of the sides of the insert bracket retaining finger  94 . 
     In this embodiment of the insert bracket  74 , the insert bracket  74  is moved into contact with the wall bracket retaining fingers  30 . Contact between the insert bracket retaining finger  94  and the retaining finger  30  causes the insert bracket retaining finger  94  to initially move inwardly and the retaining finger  30  to move outwardly until the insert bracket most outer edge  98  moves past the retaining finger lip  42 . At this point, further movement of the insert bracket  74  towards the backplate  28  causes the insert bracket retaining finger  94  to move outwardly and the retaining finger  30  to move inwardly to retain the insert bracket  74  between the retaining finger lip  42  and the backplate  28 . 
     The insert bracket  74  is concealed within the wall bracket  16  and can be placed inside the wall bracket  16  and either attached to the wall bracket  16  or the wall  12  or ceiling  14  with insert bracket fasteners  76  or adhesive or can be placed inside the cavity  36  of the wall bracket  16  without direct attachment. If it is not directly attached to the wall bracket  16 , the insert bracket  74  can be shaped so that its form holds it within the wall bracket  16  until manually deformed or squeezed so that it can be removed my moving it between the lips  42 . 
     Another embodiment of the bracket system  10  is shown in  FIGS. 1 ,  10 ,  11  and  12  that allows trim  22  to be placed between two adjoining walls  12  or between a wall  12  and a ceiling  14  (as for example, trim in the form of crown molding  26 ). In one embodiment shown in  FIG. 10 , the bracket system  10  includes a corner bracket  102  having a first wall piece  104  with a first wall piece ultimate end  106  and a second wall piece  108  with a second wall piece ultimate end  110 . Since most walls  12  or a wall and a ceiling  14  meet at a ninety degree angle, the first wall piece  104  and second wall piece  108  preferably meet at a ninety degree angle. But, where the corner bracket  102  is to be used between walls  12  or a wall  12  and a ceiling  14  that meet at angles other than ninety degrees, the angle between the first wall piece  104  and second wall piece  108  may be at an angle other than ninety degrees. Regardless of the angle between the first wall piece  104  and second wall piece  108 , it is preferred that the first wall piece  104  be flush against a first wall  112  and the second wall piece  108  be flush against a second wall  114 . The first wall piece  104  and the second wall piece  108  also preferably do not have backplate holes  32  extending through respective first wall pieces  104  and the second wall pieces  108  to attach the first wall piece  104  to a first wall  112  and the second wall piece  108  to a second wall  114  but may have backplate holes  32  if desired. 
     In a preferred embodiment of the corner bracket  102 , the first wall piece  104  and the second wall piece  108  both have a retaining finger  30  extending from their respective ultimate ends  106 ,  110 . Regardless of the angle between the first wall piece  104  and the second wall piece  108 , the wall bracket retaining fingers  30  are preferably parallel to each other and have retaining finger ultimate ends  40  and lips  42  as described above. A cavity  36  is formed between the first wall piece  104  with its corresponding retaining finger  30  and the second wall piece  108  with its corresponding retaining finger  30 . 
     The bracket system  10  that includes a corner bracket  102  also includes a trim bracket  20  as described above. In use, the trim bracket  20  is attached to the corner bracket  102  through a three step process similar to the process for connecting a trim bracket  20  to a wall bracket  16  described above. Here, the trim bracket  20  is brought into contact with the corner bracket  102  so that the trim bracket retention edges  50  move into contact with the wall bracket retaining fingers  30 . In this configuration, the retention edge  50  near the retaining fingers ultimate end  40  will be in contact with the wall bracket retaining fingers  30  near the trim bracket lip  60  but both the wall bracket retaining fingers  30  and the trim bracket retention edges  50  are in a rest or unstressed condition. 
     In the second step, the trim bracket  20  moves toward the corner bracket  102 . As the trim bracket  20  is moved toward the corner bracket  102 , the wall bracket retaining fingers  30  move slightly outwardly while the trim bracket retention edges  50  move slightly inwardly as the trim bracket most outer edge  56  moves past the retaining finger lip  42 . The wall bracket retaining fingers  30  and the trim bracket retention edges  50  are dimensioned to allow each to flex slightly as the trim bracket most outer edge  56  moves past the retaining finger lip  42  and then return to their rest position. 
     Finally, when the trim bracket most outer edge  56  has moved past the retaining finger lip  42 , the trim bracket most outer edge  56  moves outwardly again while the wall bracket retaining fingers  30  move inwardly again so that the retention edge  50  is locked into place by contact between the retention edge  50  primarily around the trim bracket most outer edge  56  and the retaining finger  30  near the retaining finger lip  42 . 
     In another embodiment shown in  FIG. 11 , the corner bracket  102  is again attached in the corner between two walls  12  or between a wall and a ceiling  14 . However, the corner bracket  102  in this embodiment is attached directly to the studs, wood paneling or any other type of wall construction material of the walls  12  or ceiling  14 , respectively where a wall covering  44  is attached to and covers the studs, wood paneling or other type of wall construction material. In this embodiment, the wall covering  44  does not extend entirely to the corner. As depicted in  FIG. 11 , the wall covering  44  that is in contact with the piece of crown molding  26  could also be pieces of trim  22  instead of or in addition to standard gypsum wall board. 
     In this embodiment, it may be desirable but not necessary for the length of the first wall piece  104  and second wall piece  108  or wall bracket retaining fingers  30 , or both the first wall piece  104  and second wall piece  108  and wall bracket retaining fingers  30  be somewhat longer than in the previous embodiment to accommodate for the absence of a wall covering  44  behind the wall bracket. Because this embodiment potentially has longer first wall piece  104 , second wall piece  108  and wall bracket retaining fingers  30 , this embodiment may also provide the advantage of more easily passing cable between the wall cavity and ceiling cavity. 
     When the corner bracket  102  is attached to the studs, wood paneling or other type of wall construction material, the trim  22  is also attached to a trim bracket  20  that is attached to the wall bracket  16  as described above. The trim  22  in this case typically is a crown molding  26 . The wall bracket  16  and the trim bracket  20  are then mated as described above thereby moving the crown molding  26  into contact with the wall covering  44  of the wall  12  and ceiling  14  or wall  12  and another wall  12  as shown in  FIG. 11 . 
     In another embodiment shown in  FIG. 12 , a structural wall  12 ′ extends between the wall  12  and the ceiling  14  or between two walls  12 . In this embodiment, the wall bracket  16  is attached directly to the structural wall  12 ′ and the crown molding  26  is attached to the trim bracket  20  as described above. The wall bracket  16  and the trim bracket  20  are then mated as described above thereby moving the crown molding  26  into contact with the wall  12  and ceiling  14  or wall  12  and another wall  12 . 
     The corner bracket  102  may also use the insert bracket  74  described above. The insert bracket  74  may be as described above where the insert bracket retaining edges  84  span between the connection of the first wall piece  104  and it corresponding retaining finger  30  and the second wall piece  108  and its corresponding retaining finger  30 . Alternately, the insert bracket  74  may be of the type where insert bracket retaining fingers  94  extend from the insert bracket retaining edges  84  and are “locked” into place by interaction between the insert bracket retaining fingers  94  and the retaining finger lip  42  of the wall bracket retaining fingers  30 . In a further alternate embodiment of the insert bracket  74 , the respective insert bracket retaining fingers  94  are formed to be conformal with the respective first wall piece  104  and second wall piece  108 . 
     The wall bracket  16 , trim bracket  20  and insert bracket  74  are each preferably formed in one piece from a rigid durable material such as bent or punched sheet metal, cast metal or molded or extruded plastic, fiberglass, composite material or ceramic. Alternately, the wall bracket  16 , trim bracket  20  and insert bracket  74  are formed from several pieces from the same or different materials. The strength and rigidity of the material of the wall bracket  16 , trim bracket  20 , corner bracket  102  and insert bracket  74  can vary depending upon the sizes of the respective pieces and the desired strength of their interconnections. 
     Where the wall bracket  16 , trim bracket  20  and insert bracket  74  are made of a material (e.g., sheet steel), these elements may be easily cut or trimmed as needed with conventional hand tools (e.g., tin snips) or power tools (e.g., cut-off saw). This allows the length of standard wall brackets  16 , trim brackets  20  or insert brackets  74  to be easily modified to required lengths prior to installation or coped for passage of cabling, etc. in and out of the bracket system  10  without compromising its effectiveness. 
     Where multiple segments of wall bracket  16 , trim bracket  20  or insert bracket  74  are used, the number of such brackets used will vary depending upon the appropriate and desired attachment strength or stability of the attaching trim  22  and the corresponding height and length of the attaching trim  22  compared with the height and length of the brackets used. Also, for larger pieces of trim  22 , it may be desired to have parallel tracks of wall brackets  16  each having its corresponding trim bracket  20  or insert bracket  74 . For standard heights of trim  22 , one row of wall brackets  16  may most preferably be used. However, if the height of the trim  22  greatly exceeds the width of the trim bracket  20 , multiple rows of wall brackets  16  and trim brackets  20  may be used to securely attached the trim  22  against the wall  12  or ceiling  14 . 
     In a variant of the invention, the bracket system  10  may be adapted to locate and securely hold a modular wall with respect to flooring  134 , other wall  12  or ceiling  14 . Consequently, another embodiment of the invention is a system of modular walls. In this system, one or more wall brackets  16  are attached to a movable wall  12 . One or more corresponding trim brackets  20  are attached to flooring  134 , other wall  12  or ceiling  14 . The movable wall  12  is moved into position so that the wall bracket  16  on the movable wall  12  mates with the trim bracket  20  on the flooring  134 , other wall  12  or ceiling  14 . 
     Another embodiment of the bracket system  10  is shown in  FIGS. 16-18  where the bracket system  10  is located on the outside corner  136  of a wall  12  to second wall  114  configuration or between a wall  12  and a recessed ceiling joist  138 . The trim  22  in all of the following three described embodiments helps protect the outside corner  136  of the wall  12  to second wall  114  or wall  12  to recessed ceiling joist  138  configuration from damage or eliminates the labor of installing, taping or mudding a corner bead on drywall or both. 
     As shown in  FIG. 16 , a single wall bracket  16  is attached to either a wall  12  or second wall  114  or recessed ceiling joist  138  near a corner  136 . The wall bracket  16  may be attached directly to the wall  12 , second wall  114  or recessed ceiling joist  138  so that the wall bracket  16  is recessed from or flush with the face of the wall covering  44  of the finished wall  12 , second wall  114  or recessed ceiling joist  138  or may project from the face of the wall  12 , second wall  114  or recessed ceiling joist  138  including being attached over the wall covering  44 . 
     The trim  22  in this embodiment is a 90° piece that is attached to a trim bracket  20  that is in turn connected to the wall bracket  16  as described above. Although the preferred embodiment of this embodiment has the trim  22  being a 90° piece corresponding to the 90° configuration of the outside of the corner  136 , where the corner  136  is at an angle other than 90°, the corresponding trim  22  would have an angle corresponding to the angle of the corner  136  whatever it is. 
     Another variant of this embodiment is shown in  FIG. 17  where two wall brackets  16 ′ and  16 ″ are attached to a respective wall  12  and second wall  114  or recessed ceiling joist  138  on each side of the corner  136 . Two trim brackets  20 ′ and  20 ″ are attached to a piece of trim  22  that is also a single 90° piece. The trim brackets  20 ′ and  20 ″ are brought into contact with their respective wall brackets  16 ′ and  16 ″ to connect the trim  22  around the corner  136  as described above. It may be necessary for one of the trim bracket retention edges  50  of one or more of the trim brackets  20 ′,  20 ″ to be trimmed or cut off ( FIG. 17 ) in order to install or remove the trim  22 . 
     Again, although the preferred embodiment of this embodiment has the trim  22  being a 90° piece corresponding to the 90° configuration of the corner  136 , where the corner  136  is at an angle other than 90°, the corresponding trim  22  would have an angle corresponding to angle of the corner  136  whatever it is. Using two pairs of wall brackets  161  and  16 ″ and trim brackets  20 ′ and  20 ″ will likely provide a more secure connection of the trim  22  to the respective walls  12  and second wall  114  or recessed ceiling joist  138  than the previous embodiment with only a single pair of wall bracket  16  and trim bracket  20 . 
     A further variant of this embodiment is shown in  FIG. 18  where two wall brackets  16 ′,  16 ″ are attached to a respective wall  12  and second wall  114  or recessed ceiling joist  138  on each side of the corner  136 . However, in this embodiment, two trim brackets  20 ′,  20 ″ are each attached to a respective piece of trim  22 ′,  22 ″ which two pieces of trim  22 ′,  22 ″, when in place through the interaction of the wall brackets  16  and trim brackets  20 ′,  20 ″, interact to form a 90° cover around a corner  136 . In this embodiment, the trim bracket  20 ′ attached to the trim  22 ′ that will be covered in part by the other piece of trim  22 ″ is first brought into contact with its respective wall bracket  16 ′ to connect this piece of trim  22 ′ next to the corner  136  as described above. Then, the trim bracket  20 ″ corresponding to the trim  22 ″ covering the piece of trim  22 ′ is brought into contact with its respective wall bracket  16 ″ to connect this piece of trim  22 ″ next to the corner  136  on the opposite side of the corner  136  as described above so that the piece of trim  22 ″ covers the portion of the second wall  114  or recessed ceiling joist  138  and, in part, the piece of trim  20 ′. 
     Again, the preferred embodiment of this embodiment has the two pieces of trim  22 ′ and  22 ″ forming a 90° cover of the corner  136  corresponding to the 90° configuration of the corner  136 . But, where the corner  136  is at an angle other than 90°, the corresponding pieces of trim  22 ′ and  22 ″ would have an angle corresponding to the angle of the corner  136  whatever it is. Further, although the configuration of the two pieces of trim  22 ′ and  22 ″ described above have been an overlapping joint, it is also within the scope of the invention that the two pieces of trim  22 ′ and  20 ″ meet with their mating edges meeting at 45° or half the angle of the angle formed by the corner  136  if such angle is other than 90°. 
     In view of the foregoing, a method for installing modular walls is also part of the invention. In this method, a movable wall  12  is provided and one or more wall brackets  16  are attached to the movable wall  12 . One of more corresponding trim brackets  20  are attached to flooring  134 , other wall  12  or ceiling  14 . The movable wall  12  is moved into position so that the wall bracket  16  on the movable wall  12  mates with the trim bracket  20  on the flooring  134 , other wall  12  or ceiling  14 . In this embodiment, the wall bracket  16  has been attached to the wall  12  and the trim bracket  20  attached to the flooring  134 , other wall  12  or ceiling  14 . However, in a variant of this embodiment, the trim bracket  20  is attached to wall  12  and the wall bracket  16  is attached to the flooring  134 , other wall  12  or ceiling  14 . 
     As described above, trim  22  is attached to the wall bracket  16 . This trim  22  is conventional finish carpentry trim of any type of readily available wood, vinyl or other trim used in residential, commercial or industrial construction. Trim  22  can be of various shapes and sizes and be used for conventional trim carpentry including, but not limited to, base board trim  116 , chair rail trim  118 , crown molding  26  or door trim  120 , window trim  122 , plinths  124  and corner pieces  126 . 
     Throughout this description, the trim  22  has been described as being primarily attached to a wall  12  or ceiling  14 . The trim  22  may also be placed against an inside or outside wall  12 , framing an inside or outside window  128  ( FIG. 13 ), around an inside or outside door frame  130  ( FIG. 14 ) or around the inside of a window frame  132  inside or on the outside of a house ( FIG. 15 ). As mentioned, the trim  22  may also be attached to the trim bracket  20  so that the trim  22  is not in contact with a wall  12  or a ceiling  14  but is instead positioned by the interconnection of the trim bracket  20  with the wall bracket  16  wherever the wall bracket  16  is located. 
     Throughout this description the “fasteners”  18 ,  24  and  76  have been used to describe connection between various parts of the bracket system  10  and the wall  12 , ceiling  14  or trim  22 . “Fasteners”  18 ,  24  and  76  means any means for attaching these respective parts including, but not limited to, screws, nails, rivets and adhesives. The adhesive may be construction type adhesive, glues or any other product suitable for connection of the respective piece to a wall  12 , ceiling  14  or piece of trim  22 . 
     There are many objects of the present invention in its various embodiments that may be addressed individually or in combinations and permutations. Consequently, each embodiment described herein may address one or several of the following objectives or benefits: 
     1. Trim  22  can be easily removed for coating or painting the finished surfaces of the wall  12  or ceiling  14  or installing wall coverings  44  for the wall  12  or ceiling  14  without working around or masking the trim  22 . 
     2. Trim  22  can be easily removed for coating or painting or refinishing of the trim  22  itself without consideration of interference with the surfaces of the wall  12  or ceiling  14 . 
     3. Base board trim  116  can be easily removed and the wall bracket  16  raised or lowered in order to raise or lower the base board trim  116  to accommodate installation of a new higher or lower flooring  134  such as new wood or ceramic flooring therefore eliminating the need to remove and renail the base board trim  116  or to install additional trim  22  to cover the outside edge of the new flooring. 
     4. No nail holes are required on the face of the trim  22  that need to be puttied or are visible. 
     5. Typically in home or building construction, wall covering  44  such as gypsum board is attached to a wall  12  first and a sub-floor flooring  134  or flooring  134  or both added later. As a result, a gap is formed between the wall  12  and the flooring  134 . The bottom of the trim bracket  20  and the trim  22  itself can be used to cover up this gap while still allowing expansion or contraction of the gap between the wall  12  and the flooring  134 . The additional width provided by the trim bracket  20  allows more room to cover up the gap than traditional construction methods. This additional room allows elimination of additional base shoe type molding (e.g., quarter round molding) to be added to the main base board trim  116 . 
     6. The wall bracket  16  and trim bracket  20  can be used with commercially available conventional trim  22 . 
     7. Trim  22  can be easily removed and reinstalled repeatedly without any change in appearance that may result from repeatedly nailing in place. 
     8. The bracket system  10  requires less coordination in timing of different construction trade&#39;s work during construction since trim  22  can be cut and fit prior to installation of the finished surface of the wall  12  or ceiling  14 . 
     9. The height taken up by the wall bracket  16  allows standard dimensional wall covering  44 , such as gypsum board, to be raised to allow higher walls  12  without the need for additional seams in the wall coverings  44  because the wall bracket  16  itself raises the bottom edge of a wall cover by the width of the wall bracket  16  when the wall bracket  16  is used next to a floor as shown in  FIG. 8  or between wall covering  44  when the wall bracket  16  is located higher up on a wall  12 . 
     10. A gap (cavity  36 ) can be created between the wall bracket  16  and the trim bracket  20  that can be used as a conduit for items such as a power cable, speaker wire, coaxial cable, telephone wire, security wire or similar wires or cabling. 
     11. Any cabling run between the wall bracket  16  and the trim bracket  20  can be easily accessed without damage to the wall  12  or ceiling  14 . This allows easy installation of new cabling after final wall construction. 
     12. Any cabling can pass in or out of the wall bracket  16  to pass cabling in or out of the wall cavity  34  or ceiling cavity  38  without visible damage to the wall covering  44  of the wall  12  or ceiling  14 . For example, for installing a new wall mounted speaker in an existing structure, a new mounting box could be cut into the wall  12 , a hole in the wall bracket  16  could be cut below the mounting box and speaker cable could be fished through the wall cavity  34  down to the hole in the wall bracket  16  and then routed through the trim bracket  20  cavity to the stereo location without any need for patching of the finished wall  12 . 
     13. Any cabling can pass in or out of the bottom of the trim bracket  20  to route underneath the trim  22  and into a room without damage to the finished wall covering  44 . For example, speaker cable can be run underneath the trim  22  and into the trim bracket  20  cavity from one side of a room where the receiver/amplifier is placed to another side of a room where it is then passed out of the trim bracket  20  cavity to where the speaker is placed with minimal speaker cable visible from inside the room. This speaker wiring can easily be installed after the wall  12  and trim  22  are installed and can easily be changed or removed at any time. 
     14. For remodeling an existing structure, the existing trim  22  can be removed and then the portion of the wall covering  44  that will be replaced by the wall bracket  16  can be removed allowing access to the wall cavity  34 . Such access to the wall cavity  34  can accommodate installation of new cabling, water piping, insulation or similar items without the need for extensive removal and reinstallation of the wall covering  44 . A wall bracket  16  can then be placed where the wall covering  44  was removed, the existing nails can be cut off the existing trim  22 , a trim bracket  20  can be attached to the existing trim  22 , and then the trim  22  can be reinstalled back on the wall  20  without the need for any restoration work to the wall  20 . 
     15. Money is saved by eliminating the need to mask existing trim  22  when initially painting or repainting walls  12  or ceilings  14 . 
     16. Removal of the trim  22  during repainting keeps a clean appearance at the joint  62  between the wall  12  and trim  22  and keeps it looking new. 
     17. The corner bracket  102  provides a flat surface for easy installation of crown molding  26  or other similar trim  22  that does not mount flush with a single surface and that often requires shimming or other bracing to assist in attachment of the trim  22 . 
     18. Typical current residential window construction includes an integral flange with the window that is attached to the outside of a house and then covered up with siding and molding. Removal or replacement of the window requires removal and replacement of the siding that covers the flange. If window construction utilized a flange that mounted to the interior of the building and had the configuration of a wall bracket  16 , the use of trim brackets  20  would allow easy access to the window flange and therefore allow easy removal or replacement of windows. 
     19. For modular type removable walls  12  that are fixed at the top and at the bottom, the use one or more wall brackets  16  at the point of attachment and corresponding trim brackets  20  on the removable wall  12 , or vice versa, would allow easy access to points of attachment of trim  22  and therefore would allow easy removal and moving of a wall  12  without requiring destruction of any portions of the wall  12 . In addition, the use of wall brackets  16  on the wall  12  with trim brackets  20  as described above would accommodate finished permanent looking wall construction with typical conventional trim  22 . 
     20. Modular walls  12  are readily positioned and securely fastened into place. When it is desired to move the wall  12 , the wall  12  is “snapped” from its anchor thereby separating the wall  12  from flooring  134 , another wall  12  or a ceiling  14 . 
     21. Trim  22  can be easily removed during removal and installation of carpeting or other flooring products so that the trim  22  does not get scratched or damaged. 
     22. Trim  22  and trim brackets  20  can be removed to allow easy installation of blown in insulation through holes in the wall brackets  16  for new and existing construction eliminating the need to insulate prior to installation of the wall coverings  44 . 
     23. Short lengths of conduit could be installed from boxes (i.e. electrical outlet boxes) to the wall bracket  16  that would allow for installation, removal and replacement of cabling after final wall construction is completed. 
     As mentioned, the brackets system  10  of the present invention has been described in connection with certain embodiments, configurations and relative dimensions. However, the description above is not to be construed as being absolutely particular. It is to be understood that the description given herein has been given for the purpose of explaining and illustrating the bracket system  10  and is not intended to limit the scope of the invention. 
     For example, the wall bracket retaining fingers  30  have been described as retaining the trim bracket retention edges  50  by physical contact where the wall bracket retaining fingers  30  are located on the outside of the trim bracket retention edges  50 . However, it is also within the scope of the invention for the wall bracket  16  to have a structure virtually identical to the trim bracket retention edges  50  and for the trim bracket  20  to have a structure virtually identical to the wall bracket retaining fingers  30 . In this embodiment of the invention, the wall bracket retaining fingers  30  now located on the trim bracket  20  will be on the outside of the trim bracket retention edges  50  now located on the wall bracket  16 . 
     In addition, the specific dimensions and configuration of the components of the bracket system  10  may be varied so long as the dimensions and configurations of the bracket system  10  provide the function of facilitating the removable connection or trim or removable walls. Also, there are many materials and configurations that can be used in constructing the bracket system  10  that will be well understood by those skilled in the art including those being developed or that will be developed. In addition, it is clear than an almost infinite number of minor variations to the form and function of the disclosed bracket system  10  could be made and also still be within the scope of the invention. Consequently, it is not intended that the bracket system  10  be limited to the specific embodiments and variants of the invention disclosed. It is to be further understood that changes and modifications to the descriptions given herein will occur to those skilled in the art. Therefore, the scope of the invention should be limited only by the scope of the claims.
