The invention is generally directed to connectors that join together adjoining edges of sections of sheet material, and methods of their use.
In the field of the construction and repair of walls and ceilings, a challenge exists in joining together two adjacent sections of wallboard, drywall, plywood or the like into a contiguous, non-broken wall or ceiling. Specifically, it is difficult to join the pieces in a smooth and contiguous manner without bulges or depressions appearing in the finished, wall. Given the extreme planar nature of modern sheet material, such unevenness is obvious to any viewer of the finished wall, leading to an unsatisfactory final effect.
One common occurrence that makes the joining of two sections of wallboard even more challenging is that when the two sections of sheet material are joined together, the point at which the sheets are joined often does not overlap with a supporting stud or beam. As a result, there is not proper support for the sheet material. This lack of support can exacerbate the unevenness between sections of wall requiring additional labor to smooth the walls out using a spreadable overlay material, or cutting the sections of sheet material to ensure that they do coincide with an underlying support, which can lead to significant waste of sheet material.
In many embodiments, the invention is directed to methods and apparatus for joining together adjoining sections of a sheet material, such as, for example, drywall.
Many embodiments are directed to sheet material connectors including:
In other embodiments the longitudinal edges of the second wall are angled outward from the pair of channels.

Additional embodiments and features are set forth in part in the description that follows, and in part will become apparent to those skilled in the art upon examination of the specification or may be learned by the practice of the invention. A further understanding of the nature and advantages of the present invention may be realized by reference to the remaining portions of the specification and the drawings, which forms a part of this disclosure.
The description and claims will be more fully understood with reference to the following figures and data graphs, which are presented as exemplary embodiments of the invention and should not be construed as a complete recitation of the scope of the invention.
Turning now to the drawings, apparatus and methods for joining sections of sheet material (e.g., drywall) are provided. Many embodiments of sheet material joining apparatus or connector comprise an elongated body having two channels disposed such that the ends of two sections of sheet material may be secured therein. In various embodiments the channels are defined by front and back walls interconnected via an internal rib. In some such embodiments the front wall is configured to be disposed on the exposed side of the sheet material and the back wall is configured to be disposed on the back or hidden side of the sheet material. In embodiments the back wall takes the form of a convex arced surface. In some such embodiments the convex arced surface is configured to be engaged by one or more securing elements (e.g., screw), and during such engagement to exert a resilient force onto the adjoining sections of sheet material to draw them inward toward the back wall of the connector.
According to embodiments, the connector may be used to join any suitable sheet materials. Although references may be made to drywall in particular example, it will be understood that the term sheet material as used in reference to the present invention refers to drywall, sheet rock, gypsum board, wallboard or similar wall panels. In embodiments, the joining may occur at any point along a framed wall without support such that framing members may take any desired configuration, such as, for example, 16″, 18″ or 24″ on center. The channels and elongated bodies of the connector may be configured for any desired thickness and length of sheet material. The joining connector and methods in accordance with embodiments may be used for wall or ceiling installation.
Referring to
In various embodiments, the connecting wall portion 16 is dimensioned 22 such that the channels 18 and 20 are sufficiently sized to allow the sheet materials to be loaded into the channels and held thereby. In some such embodiments the channels 18 and 20 may have a width dimension 22 such that they are slightly smaller than the width of the sheet material to be joined such that the walls apply a resilient force thereto. In other embodiments the channels may have a dimension 22 such that they are slightly larger than the width of the sheet material to be joined such that they may be inserted without damage thereto.
In some embodiments, as shown in
Finally, as shown in the cross-section, in many embodiments the rear wall 12 is formed as a curved arced surface concave to the connecting wall such that the wall exerts a resilient load force on sheet material inserted into the channels 18 and 20. As will be described in greater detail below, these arced portions 32 and 32′ of the rear wall 14 are also configured to be used in conjunction with attachment means (e.g., screws and other fasteners) to place tension on the arced wall, thereby increasing the resilient force being placed on the two adjoined sections of sheet material, thus causing the edges of the sheet material to draw into the bay or cavity between the wall studs at the rear of the sheet material wall to further minimize the formation of bulges or discontinuities in the finished wall.
In embodiments, the connector 10 may be fabricated from any material suitable to provide sufficient support to the ends of the sheet material. In particular, the connector 10 may be made of a material sufficiently rigid to substitute for traditional support structures, thereby enabling the connector to be used at wall locations in which no stud is provided, or to use the connector as a substitute for a conventional support structure (e.g., wooden or metal stud) at an intermediate location of the wall. Exemplary materials include, for example, metals (e.g., aluminum or steel), polymeric materials (e.g., plastics such as PVC, etc.), and cellulosic material (e.g., compressed cardboard).
The connector can be provided in lengths of 4 ft., 8 ft., 12 ft. and 14 ft., which are common drywall width and length dimensions or other customized lengths. The connector can be used on horizontal or vertical orientation extending vertical wall drywall applications or on ceilings (as will be described in greater detail below. The connector may be any color or consistency. In some applications, the connector may be translucent to allow the edges of the drywall to be visible. The connector may be dimensioned for standard ground thickness for drywall such as ¼ in., ½ in., ⅝ in., ¾ in. or other smaller or larger ground thickness drywalls. Images of exemplary embodiments of such connectors may be seen, for example, in
Referring to
After the two sections of the sheet material are adjoined through the connector, fasteners 38 are driven through the exposed side of the sections of the sheet material and into the front face of the rear walls 16. As the fasteners 38 are tightened the convex arced rear wall is pulled inward toward the back side of the sheet materials thereby increasing the force applied by the convex arced rear wall of the connector on the adjoined edges of the sheet material. (Exemplary illustrations of these steps are provided in
As shown in
As discussed previously, the connector 10 of the present invention can be employed in connection with installing, repairing or patching a damaged wall section. Alternatively, as shown in
As in the embodiments shown in
Using the sheet material connectors in accordance with embodiments, it is not only possible to obtain better joining (as described in detail above), but to allow the joints between the sheet material to occur at random along the new construction, regardless of the position of the underlying supports. More specifically, it is possible to use the sheet material connector according to embodiments to serve as a replacement support where two sheets of material do not happen to align with an underlying stud. As a result of this capability, the speed of construction can be accelerated, and the amount of material wastage can be reduced.
While the above description contains many specific embodiments of the invention, these should not be construed as limitations on the scope of the invention, but rather as an example of one embodiment thereof. Accordingly, the scope of the invention should be determined not by the embodiments illustrated, but by the appended claims and their equivalents.
