This provides for the creation of a small gap or cavity between the point 51 of tooth 47 and the short side 50 ′′ of tooth 47 ′′ in which fabric material can bunch up and be securely held.

Abstract
Description
- The invention is generally related to stretched fabric panels used for architectural and acoustic interior treatments and, more particularly, to molding strips used to secure the stretched fabric to a support surface such as a ceiling or wall.
- Architectural fabric ceiling and wall systems have been used for several years to enhance interior acoustics and the appearance of interior spaces in homes, buildings, rooms, and the like. These systems can provide color, texture, and three-dimensional features to a ceiling or wall which cannot be duplicated by other surface treatments. Typically, these systems include a number of extruded molding strips which frame an area over which a fabric is stretched. The extruded molding strips, also referred to as track, are affixed to a support structure such as a wall or ceiling using screws, nails, adhesives, or other securing means as appropriate, and have a retaining mechanism for retaining the fabric. The area which is framed by the track can be any shape or size. After the track frames the area, the fabric is stretched over the frame and secured in the retaining mechanism. The fabric can be any material which can be held by the retaining mechanism. The fabric is often a cloth material, and the cloth may be textured or patterned with a design.
- The retaining mechanisms which have been employed in prior art systems typically include a pair of spring biased walls which have opposing jaw members. In operation, the fabric is pushed between the jaws using a knife or other suitable flat object. The fabric accumulates in a cavity between the jaw members, and, if necessary, can be trimmed using a knife or shears at the location of the retaining mechanism after it is inserted into the cavity. Because the extruded members provide a frame for the area of interest, the procedure of stretching the fabric over the frame and stuffing the fabric into the retaining mechanism region of the frame members assures that a smooth fabric surface is presented. The framed unit is often referred to as a stretch fabric “panel”.
- The fabric panel may be positioned over a tackable core material, such as, for example, in wall applications where it is desired to permit pictures and other objects to be hung on the wall over the fabric panel. In addition, the fabric panel may be positioned over acoustical core materials (i.e., fibrous or foam insulation) which attenuate sound, as would be needed in auditoriums or recording studios. Furthermore, electronic equipment, such as speakers, microphones, and the like, may be positioned behind the fabric panel within a mounting frame or region.
- The choice of material used for the fabric will depend on the application. In acoustic applications, it will be desirable to use loose weave materials which will allow free passage of air between the room and the sound attenuating foam or fibrous material. This will allow, in the case of embedded speakers, sound to be projected clear and undistorted into the room from the speaker, and, in the case of using acoustical cores to deaden undesirable noise, and will prevent undesirable noise from being reflected into the room. For wall or ceiling applications which are decorative in purpose, fabrics with a tighter weave and other specific characteristics will be preferred. Cloth as well as metal wire and extruded plastic fabrics can be used.
- The panels need not be rectangular in shape. In fact, the edges of several adjacent fabric panels can be organized in a manner which creates parallelograms, triangles, and other geometric shapes on the treated wall surface. In addition, the extruded pieces can be fashioned so as to create bevels, curves, and spaces between adjacent panels.
- Several patents describe stretch fabric panel systems. These include U.S. Pat. Nos. 4,631,882, 4,731,960, and 4,788,806 all to Sease; U.S. Pat. Nos. 4,018,260, 4,053,008, 4,151,672, 4,161,977, 4,197,686, and 4,625,490 all to Baslow; and U.S. Pat. Nos. 5,117,598, 5,214,892, and 5,953,873 all to Livingston. Each of these patents is herein incorporated by reference.
- Despite the widespread use of fabric panel systems, improvements in molding strip designs for use where two surfaces meet perpendicularly would be advantageous. Most fabric panel systems can only fit into a perpendicular edge with removal of certain sections of the wall track to be inserted. This impediment of the fabric panel systems makes the installation more difficult due to an addition of steps and the increased possibility of error in the installation. In addition, prior art stretch fabric panel systems often retain opposing jaw members in an interlocking pattern or have no jaws present at all. Accordingly, there is a need for a molding system which retains the dual ability to be applied at an edge of two perpendicularly intersecting surfaces without modifying the original design, and which possesses an inward gripping teeth formation which benefits the homeowner and professional alike.
- An object of the present invention is to provide molding strips for fabric wall and ceiling systems which retain the dual ability of being applied at a surface or setting at an edge where two surfaces intersect perpendicularly without the need to modify the molding strip.
- Pursuant to this and other objects of the present invention, a fabric panel molding has a protruding portion in a longitudinal direction and a base with a wall contact surface. There are at least two separate fabric receiving cavities, each with gripping members at a fabric tuck point, such as a first and second flexible gripping wall having gripping surfaces. In a preferred embodiment, one fabric receiving cavity (also referred to as a collection cavity) is adjacent to the base while a second fabric receiving cavity is spaced away from the base by the first cavity. Each cavity includes an entry tuck point for inserting a portion of fabric material and a gripping member for gripping the inserted fabric.
- An advantageous feature of this invention is that it can be used effectively on a wall or a ceiling surface that abuts an adjacent wall or ceiling surface that does not abut against an adjacent surface. For example, when the molding strip abuts an adjacent wall or ceiling, fabric can be tucked into a collection cavity spaced away from the base, and when the molding strip does not abut an adjacent surface, fabric can be wrapped around the strip to cover it completely and be tucked into a collection cavity adjacent the base.
- A variety of gripping members may be employed at the tuck points which permit fabric insertion into the collection cavities. In a preferred embodiment grip members, such as these in patent in U.S. Pat. No. 5,953,873 to Livingston which is herein incorporated by reference. In this preferred embodiment, two of the pluralities of gripping teeth are formed of two separate tooth grip surfaces substantially perpendicular to a common plane. The first and second tooth grip surfaces of each of the first and second plurality of gripping teeth form a projecting point extending longitudinally along the extrusion. The other two pluralities of gripping teeth are formed of two separate tooth grip surfaces substantially parallel to a common plane. Both sets of gripping teeth are arranged such that the point of each tooth projects into a cavity between a corresponding two teeth. In the absence of a secured fabric, the teeth may mesh with the point of one tooth contacting a second tooth grip surface in a central region or being positioned only slightly away from the second tooth grip surface. The flexible gripping walls and plurality of gripping teeth are arranged such that a fabric inserted into the fabric entry slot first contacts the angled second surface of a first of the first plurality of gripping teeth, passes over the point of the first gripping tooth, which slightly deflects the first gripping wall due to the fabric passing between the point of the first gripping tooth and the second angled surface of a first of the second plurality of teeth. The teeth configuration makes it easier to move fabric into the fabric receiving cavity than to remove the fabric from the fabric receiving cavity, and thereby combats unintended dislodgement of the fabric from the fabric receiving cavity.
- The foregoing and other objects, aspects, and advantages will be better understood from the following detailed description of the preferred embodiments of the invention with reference to the drawings, in which:
-

On the left side, a fabric material is inserted in a first collection cavity close to the base. On the right side, the fabric material is inserted into a collection cavity spaced away from the base. The left side arrangement is preferably used when the molding strip does not abut against a ceiling or side wall, while the right side arrangement is used when the molding strip abuts against a ceiling or side wall. -
FIG. 4 is a cross-sectional, enlarged view of a material being inserted between the gripping teeth according to an embodiment of the invention. -
FIG. 1 shows the cross-section of amolding strip 8 for fabric wall and ceiling systems according to an embodiment of the invention. Themolding strip 8 comprises abase 10 and a protrudingportion 14 which extends from thebase 10. Thebase 10 is securable to a substrate such as a wall, ceiling, or other surface onto which a stretch fabric panel will be created. The protrudingportion 14 contains two collection cavities, 16 and 18.Collection cavity 16 has anentry tuck point 20 to permit insertion of material and a grippingmember 24 for gripping the material after it is inserted into thecollection cavity 16.Entry tuck point 20 is located towards a protrudingend 28 of protrudingportion 14. Thecollection cavity 18 has anentry tuck point 22, adjacent tobase 10, and a grippingmember 26.Collection cavity 18 is positioned adjacent to the base 10 whilecollection cavity 16 is spaced away from said base bycollection cavity 18. - As shown, gripping
members fabric gripping regions panel molding strip 8. Other types of gripping members may also be used - The longitudinal dimension of the molding strip 8 (into the paper) can be any desired length from, for example, a few inches to several feet. The height of the protruding
member 14 from the base 10 can vary depending on the application. For example, in many aesthetic or acoustic applications, the protruding member can be 0.5″ to 5″ in height, and will often be 1″ to 3″ in height. If speakers or acoustic fill or board is to be placed behind the fabric, the protrudingmember 14 will preferably be high enough above the base to allow covering the speakers or acoustic fill or board without having to stretch over top of the speakers or acoustic board. - The molding strip is preferably made from extruded plastic, such as, for example, polyvinylchloride, polypropylene, or polyethylene as stated in U.S. Pat. No. 5,953,873 to Livingston.
- The
base 10 has abase wall 30 and has opposing side edges, 32 and 34. Aside wall 36 extends generally perpendicularly frombase wall 30 fromside edge 32. For example, depending on the application, theside wall 36 may form an 80° to 100° angle withbase wall 30. As depicted, it forms an approximately 90° angle withbase wall 30. - A
web member 38 preferably connects thebase wall 30 to theside wall 36. Theweb member 38 preferably connects to thebase wall 30 at aconnection point 40 between opposing side edges 32 and 34 with thecollection cavities side wall 36 and theconnection point 40, and with an extendingmember 42 extending beyond theconnection point 40. The extendingmember 42 can be used to secure the molding strip to the substrate with tacks, screws, nails, glue, etc. Alternatively, screws could pass directly through theweb 38 andbase wall 30 into the substrate. - The
collection cavity 18 has anentry point 22 between theside wall 36 and thebase wall 30. Thecollection cavity 16 has anentry point 20 between theside wall 36 and theweb member 38.Web member 38 preferably includes aprotruding end 28 which protrudes in alignment with the protruding end of theside wall 36, and theentry point 20 between theside wall 36 and theweb member 38 is located between the top portion of theside wall 36 and theprotruding end 28 of theweb member 38. -
FIG. 2 shows a perspective view ofmolding strip 8 according toFIG. 1 . Themolding strip 8 has a base 10 which is substantially flat and a protrudingportion 14 which are both elongated, as shown inFIG. 2 . A back side of thebase portion 10, thebase wall 30, is placed against a wall or other surface to which themolding strip 8 is to be attached. If themolding strip 8 is being attached to an intersection of a wall and a perpendicular surface, the back side of said base portion is attached to the wall or other surface and theside wall 36 is placed abutting against the perpendicular surface. -
FIG. 3 shows a cross sectional side view of a fabric panel molding and its mirror image when amaterial 44 is stretched between the two moldings according to an embodiment of the invention. Thefabric material 44 will typically be a woven cloth, and can be patterned with designs or be of a solid color, and can have rough or smooth texture, depending on the architectural requirements for the space receiving the treatment. In addition, as discussed above, in acoustic treatment applications or in applications where speakers are positioned behind thefabric material 44 it will be desirable to have afabric material 44 which allows free passage of air to the sound attenuating materials (e.g., fibrous or foam materials). Thebase molding strip substrate 12. Amaterial 44 is inserted intocollection cavity 18 then wrapped around theside wall 36 and inserted in the lower tuck point, conversely, inmolding strip 8′ which is, for example, in contact with the perpendicularlyadjacent substrate 12′ (e.g. wall, ceiling, etc.),material 44 cannot be received bycollection cavity 18′ due to interference bysubstrate 12′. Rather, thematerial 44 is inserted in thecollection cavity 16′ to complete the connection between the molding strips 8 and 8′. Since thematerial 44 is stretched around themolding strip 8 to thecollection cavity 18, and is inserted in thecollection cavity 16′, the decorative design of the said material is presented as complete and smooth without any harm to the material. -
FIG. 4 shows an example of opposinggripping sections member 24. Eachtooth 47 has along side 49 and ashort side 50. Theshort side 50 projects approximately perpendicular or normal to the grippingsection point 51 of thetooth 47 is directed downward and is closer to thefabric collecting cavity 16 than the base of thelong side 49. Thepoint 51 is directed towards a central region of thelong side 49′ of an opposingtooth 47′ and serves to trap and retain fabric (not shown) between thepoint 51 and thelong side 49′. In some applications it may be desirable to have thepoint 51 contact thelong side 49′; however, having a small gap which is preferably smaller than the fabric to be inserted intofabric collection cavity 16 may provide for ease in stuffing the fabric into thecavity 16 between grippingsections sharp point 51, as is shown inFIG. 4 . However, the pressure fit between thepoint 51 andlong side 49′ is responsible for resistance to fabric dislodgement fromcavity 16; therefore, having rounded or squared off points can also provide to be advantageous within the practice of this invention. In the preferred embodiment, the angle created by thelong side 49 andshort side 50 of the tooth 47 (or by planes passing through thelong side 49 andshort side 50 of the tooth 47) ranges between 35 degrees and 55 degrees, and is most preferably 45 degrees. This provides for the creation of a small gap or cavity between thepoint 51 oftooth 47 and theshort side 50″ oftooth 47″ in which fabric material can bunch up and be securely held.
