E04b 5/52; E04c 1/00 U.S. Cl. 52--311 2 Claims ABSTRACT OF THE DISCLOSURE A beam of matted fibers is grooved along opposite, longitudinal edges to serve as a starting strip to support ceiling panels having tongue and grooved edges. The beam is provided with a thin decorative lm.
BACKGROUND OF THE lINVENTION Field of the invention This invention pertains to a ceiling suspension member and system, and more particularly to a ceiling suspension member which enables facile and economical installation of panel members in a particular decorative assembly.
Description of the prior art In the building construction field, and more specifically, in the eld of home improvement projects, rooms may be made more attractive and functional by the installation of preformed panels or tiles.
In general, the home improvement market has a need for a simple and inexpensive suspension member and means for installing ceiling panels or tile. The appearance of old and cracked ceilings can be greatly improved and their attractiveness enhanced by the installation of ceiling panels by the home owners themselves. Among the least complicated means for installing a ceiling is the direct nailing or stapling of ceiling panels to the flat overhead or to spaced furring strips.
The ceiling panels are generally rectangular and have two adjacent sides which are kerfed to form grooves having upper flanges coextensive with the back of the tile, extending outwardly beyond a bevelled recessed portion below the grooves. The other two adjacent sides have upper recessed areas and tongues of each panel are adapted to be received in the grooves of adjacent panels to t tightly therein and support the tongued edges of the tiles. The extending flanged edges above the grooves are nailed or stapled directly to the overhead or to furring strips thereon.
For a more detailed description of a suitable type of ceiling panel or tile, reference may |be had to the disclosure of U.S. Patent No. 2,341,645. In describing the manner of installing the ceiling tile, the patent clearly discloses that the center lines of the wall or ceiling are rst formed and the odd dimensions from the edges are laid out so that the tile may be laid with the odd dimension size tile, that is, the tiles are so laid that the tiles are started from the edges of the wall or ceiling surface rather than started from the center of the room.
It 4should be realized that the specific shape of the grooves and flanges is not to be rigidly construed to be that of the reference patent, It is suicient that they be complementally formed so that anges are received in the grooves to form a secure t. After the first row is installed, each subsequent row must be put up in order, progressing across the room until the opposite wall is reached. A border trim is installed to nish the ceiling.
vOne of the difficulties, especially for the amateur, is the problem of accurate measurements in cutting the rst row of panels or tiles so that the last row can be installed with an even border at each wall of the room. It is infrequent that any room will be an even multiple of the dimensions of the panels and so almost inevitably a certain -amount of cutting of the border tiles will have to be done before the job is started. Any miscalculation can result in a totally ruined ceiling.
In modern decor, the use of a wood beam as an integral part of a yceiling has been popular in certain types of rooms. If these beams are fashioned from natural wood, cut and nished for interior application, they are very expensive. Certain substitutes such as v'eneered plywood or even hollow, thin sheet metal beams with laminated vinyl coverings simulating wood beams have been used. Such simulated metal beams do not form a part of the suspension system but merely are attached to the ceiling; generally, to the suspension members. Folded cardboard simulating wood beams have been tried, but they are generally too flimsy to supply a supportive function. In addition, the machinery used to fabricate the simulated wood beams from cardboard or sheet metal differs from that generally available in the ceiling panel manufacturing plant and requires an additional capital expenditure to fabricate.
It is, therefore, an object of the present invention to provide a novel suspension member and system which add a decorative appearance to a room.
It is yet another object of the present invention to provide a novel suspension member and system which simplifies the installation of a panel ceiling.
SUMMARY OF THE INVENTION The present invention is directed to a novel suspension member which is used as a starter strip in the center of a ceiling and a ceiling system which allows rows of ceiling panels or tiles to be easily erected in serial rows in two directions from a centerline. The panels of the outermost two rows are cut to size before being secured in place. Since the required width of the outermost two rows can be easily measured, the installation is very simple and ycan be done with accuracy by an amateur. In contrast to this, the other method of starting at one wall and placing rows of panels until the other wall is reached, requires extreme care in the yfirst measurements, or the entire ceiling will 'be unsymmertrical and unsightly.
In addition, the novel suspension member can easily be manufactured to simulate a wood beam for decorative effect.
BRIEF DESCRIPTION OF THE DRAWING These and other objects and advantages of the invention will become more apparent from the following description taken in conjunction with the accompanying drawing in which like `figures represent like elements and in which:
FIGURE 1 is a perspective view of a portion of -a -ceiling incorporating the suspension member of the invention;
FIGURE 2 is a cross-sectional view of a portion of the ceiling of FIGURE l, taken along lines 2 2 thereof;
FIGURE 3 is a perspective View of a portion of a ceiling showing an alternative variation of the invention, and
FIGURES 4 and 5 are detailed perspective views of the novel suspension members of the invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to FIGURES 1 and 2, there is shown a portion of a ceiling 10 suspended from typical furring `strips 14. The forward or leading edge of the ceiling is shown with a row of panels removed to expose the furring strips 14, although it will be understood that the forward end would ordinarily rest against a wall of the room in which the ceiling is installed. Furring strips 14 are arranged in parallel relation and spaced at multiples equal to the width of a row of ceiling panels.
A center beam 16 forms a support for ceiling tiles or panels and is placed along a centerline of the room to which the ceiling is to be applied and secured to furring strip 14 by nails or staples 13 which are driven through the outwardly extending flanges 20 of beam 16. Longitudinal grooves 22 and 23 are cut into the sides of beam 16 immediately below flanges 20. As will be explained hereinafter, the thickness of flange 20 is equal to the depth of recess along adjacent edges of ceiling tiles. Sufficient nails or staples 18 are used to hold the center beam in place. Individual ceiling tiles 25 are inserted with their tongues 27 inserted in the longitudinal groove 22. The opposite sides of tiles 25 have flanges 30 which are secured to furring strips 14. A second row of ceiling tiles 31 is then placed in position with the tongues of the tile inserted in corresponding grooves of tiles 25. As was the case with tiles 25, the flanges 33 along the edges of tiles 31 opposite their tongues are secured to furring strips 14.
To the other side of center beam 16 are placed a first and a second row of ceiling tiles 37 and 3S respectively. The tongues 39 of the tiles of row 37 are inserted in. grooves 23 of center beam 16 while the flanges of the opposite edges are secured to furring strips 14 (not shown). The tongues of the tiles of row 38 are inserted in the grooves of the tiles of row 37 and their opposite flanged edges are in turn secured to furring strips 14. For further holding strength, additional furring strips may be added at right angles to furring strips 14 and arranged to be spaced to receive flanges of the ceiling tiles.
With further reference to center starting lbeam 16, a more decorative and attractive ceiling can be achieved, if the center beam is made to simulate a wood beam. The basic material of the wood beam is lignocellulose fiber formed into a mat on a fourdrinier or cylinder machine. lt is well known to manufacture insulation board from bagasse, or other vegetable fiber, by first refining the vegetable matter to form fibers, then forming a mat by the deposition of a thin aqueous suspension of refined fibers on a board forming machine and subsequently dewatering the mat with final drying. The mat can, if desired be conveniently made in an extended sheet of about l inch in thickness. Various thicknesses of mat can be laminated with waterproof glue to form a mat of greater thickness. In the beam of the present invention, it has been found to be advantageous to form the beam and then cover it with a thin laminate of vinyl film. The beam may be grooved as at 22 or 23 by a rotary cutter. It is important, however, that the flanges 20 extend outwardly beyond the sides of beam 16 so as to provide an easy means of nailing the beam to an overhead support. The beam 16 may be of any convenient length to span the ceiling. Preferably a single length of beam should be used but, obviously, beams can be abutted longitudinally to simulate a single beam.
After the center beam 16 has been secured to an overhead along a centerline of the room by nails 1S through its flanges 20, the ceiling panels 25 are placed in position with their flanges 27 inserted in grooves 22. The cut back section of panel 25 mates with the flange 20` of beam 16 and forms a snug fit. The opposite side of panel 2,5 has a flange which is secured to the furring strip 14. An additional row of ceiling panels 31 can be then put up to form a subsequent row f panels. If desired another simulated wood beam 40 may be used in place of another row of panels. This latter beam 40, however, will not have grooves on both sides but in crosssection will have grooves and flanges corresponding to the cross-section of the ceiling panels. Additional rows of ceiling panels may be put up until the edge of the room is reached. It may be necessary to cut the edges of the last row of panels to fit them in. However, a wall strip can -be used in the conventional manner to trim the edge of the ceiling.
Similarly, the other half of the ceiling can be installed by placing a row of panels 37 (to the left of beam 16 as shown) with the flanges of panels 37 inserted in grooves 20 on the side of beam 16 opposite the grooves which received panels 25. The other half of the ceiling is completed as above described by adding rows of additional panels as required.
An alternative type of ceiling is shown in FIGURE 3 wherein beams 42 and 43 are simulated wood beams similar to beam 16 shown in FIGURE l. The beams 42 and 43 are grooved, as at 45 and 46 and are secured to the overhead at spaced intervals equal to the dimension of panels 50. Panels 50 are not grooved and flanged in the manner of panels 25 but rather are flat platelike members the edge of which are inserted in the grooves of beams 45 and 46. If desired, beams 55 and 56 may be placed at right angles to beams 42 and 43 and interlocked therewith.
For a more detailed view of the interlocking of beams 55 and 40, reference may be had to FIGURES 4 and 5 which show clearly groove 46 of beam 42 and a flange 58 extending outwardly of beam 55. Flange 58 is inserted into groove 46. The area 59 of beam 55 above flange 58 is recessed to receive the flange above and beyond groove 46 of beam 42 to give a secure snug fit. The faces 60 and 65 of beams 40, 41 and 55 are covered with a plastic film which is grained to simulate wood. The film may be glued evenly over the surface after the fiberboard beam is cut. The film may be printed paper is desired. If desired, the beams may be coated with selected paint or other finishes to provide a Wide variety of decorative choices.
It should be realized that while cross-sectional shape of the beam has been illustrated and described as rectangular, other cross-sectional configurations could be employed. For example, the outer corners of the beam could be rounded off rather than being rectangular or the entire exposed surface could be semi-circular, triangular or other geometrical shape.
Also, while the major emphasis has been placed on lignocellulose fibers as the preferred material, other materials such as plastic or metal could be used. However, it should be understood that since the beam is preferably used in more economical construction where lignocellulose ceiling tiles or panels are used, the manufacture of the ceiling beam from the same material can be easily and cheaply done by using the same basic equipment and machinery.
