Register assembly

Abstract

In one embodiment, the invention is a register assembly for inserting into floors, ceilings and walls, comprising a first open top box having a bottom surface, which defines a centrally disposed opening through which air flows from a first environment to a second environment. A support is disposed within the first open top box. A second open top box nests within the first open top box, and is supported by the support. A restraint is associated with the first and second box to restrain the second box within the first box. The first and second open top boxes are sized and dimensioned to be coplanar with each other when nested. A conduit is also defined between the first open top box bottom surface opening and the second open top box to flow air from the first environment to the second environment.

DESCRIPTION

(10) The present invention is a register assembly for an air duct. The register assembly can be installed in a wall, ceiling or floor. In the example shown in FIG. 1, the register is installed in the floor (60) so that all components of the assembly are coplanar with each other, and with the surrounding floor.

(11) In its most basic form, the assembly is comprised of two components, namely a register body (20) and an insert (30) (see FIG. 2). As best viewed in FIG. 4, the register body (20) resembles an open top box comprising a bottom surface (150) and two pairs of opposing sidewalls (180, 190) enclosing an interior, into which the insert (30) is inserted (see also FIG. 2). The bottom surface (150) defines a centrally disposed opening (FIG. 5, 70) for air to flow from a first environment to a second environment.

(12) The insert (30) (see FIG. 4) also resembles an open top box comprising a bottom surface (140) and two pairs of opposing sidewalls (160, 170) enclosing an interior. The insert (30) is sized and dimensioned to be nested and restrained within the register body (20) so that the body (20) and insert (30) are coplanar with one another, and with the surrounding floor, ceiling or wall. There is also at least one support (100) disposed within the register body thereby ensuring there is a conduit (FIG. 1, 50) formed between the insert (30) and the body (20) when the insert (30) is inserted and restrained within the body (20). The arrows in FIG. 1 represent the movement of air out of the register assembly (10) from a first environment to a second environment.

(13) The conduit (50) is in communication with the body bottom surface opening (70) and permits air to flow from the first environment to the second environment. Said first and second environments contemplates a variety of situations, including, ventilating a room inside a building with air from outside the building, providing air flow between two rooms in a building, and providing heated or cooled air from an air duct to a room.

(14) In a preferred embodiment, the register body (20) and insert (30) are manufactured from a suitable metal or plastic. To create the bottom opening (70) in a metal register assembly according to the present invention, the body bottom surface (150) is cut or stamped out along lines (C3) and (C4) as shown in FIG. 4A. An advantage of this method is that the support (100) for the insert (30) is integrated with the the register body (20) as will be described. The now moveable portions of the bottom surface (150) are folded upwardly along lines C-D until perpendicular to the bottom surface (150). A second fold downward towards the bottom surface (150) is made along lines E-F. The two folds result in an L-shaped support (100), extending upwardly from the bottom surface (150) of the register body (20), as shown at the right-hand side of FIG. 4A and in FIG. 4C. The left-hand portion of FIG. 4A and corresponding FIG. 4B show the register body (20) prior to the first and second folds at lines C-D and E-F.

(15) A restraint is used to restrain the insert (30) within the body (20). In a preferred embodiment, said restraint is a cooperative engagement between the insert (30) and the body (20). An example of a cooperative engagement, in the form of a male-female locking mechanism, is shown in FIG. 5. An opening having a narrow portion (120) and a wide portion (110) can be created in each of the L-shaped supports (100) (FIGS. 4A and 5). The openings (110, 120) form the female portion of a male-female locking mechanism to restrain the insert (30) within the body (20).

(16) To create the male portion, the bottom surface (140) of the insert (30) can be modified to have two openings (130) from which T-shaped projections (90) extend (FIGS. 3 and 4). To create the openings, the insert bottom surface (140) is cut or stamped out along line C1 and folded downwardly along lines A-B away from the bottom surface of the insert (140). This results in a T-shaped projection (90) that extends orthogonally from the bottom surface of the insert (30; see FIG. 4 and FIG. 5). Optionally, bottom surface (140) can be cut or stamped out along line C2 (FIG. 3A) to create the rectangular opening (130) as illustrated in FIG. 4 and FIG. 5.

(17) As illustrated in FIG. 5, the T-shaped projection (90) of the insert (30) is inserted into the opening wide portion (110) of the register body L-shaped support (100). Once inserted, the T-shaped projection (90) can be slideably inserted into the opening narrow portion (120), thereby restraining and locking the insert (30) onto the register body support (100).

(18) The T-shaped projection (90)/L-shaped support (100) combination is not the only means of securing the insert (30) to the body (20). Many other types of male-female connectors, adhesives and connectors can be used to accomplish the same function.

(19) To complete the register assembly, a faceplate (40) can be installed within the insert (30). The faceplate (40) (FIG. 1 and FIG. 4) is removable and customizable so that any type of faceplate can be inserted within the insert (30). The faceplate (40) is easily manufactured to match the surrounding wall, ceiling or floor. The surrounding floor, ceiling or wall can be any one of marble, carpet, granite, wall painted a particular colour, wall covered in wall paper, and any other suitable material. All that is required is a matching faceplate (40) cut to the appropriate size to fit within the insert (30). A homeowner can purchase a register body (20) and insert (30) and can easily manufacture a matching faceplate (40) using materials and tools at home.

(20) In other embodiments, movement of air through the register can be controlled by attaching a damper (FIG. 2; 140) onto the the bottom surface (150) of the register body (20). In another embodiment, the faceplate (40) can be replaced with a humidifying unit.

(21) In yet another embodiment, the register body (20) can be manufactured to be installed in an “undermounted” fashion to make the register assembly even less visible.
