Abstract

A wallboard fastener has a pair of flanges 22 on opposite sides of tongue portion 16 and a pair of impaling flanges 24 mounted to flanges 22 so as to extend over and parallel to base portion 14. The fastener includes apertures 18, 20 in both the base portion and the tongue portion and separate ribs 28, 30 are provided for the base portion and the tongue portion so that the tongue portion 16 is severable from the base portion 14 without deforming the rib structures. The fastener may include an additional rib structure 32 disposed across the interspace between the ribs in the base portion and the ribs in the tongue portion, and which is offset from the ribs of both portions. In use the flanges 24 penetrate an end face of a panel and a screw etc is passed through either aperture 18 or aperture 20 to secure the panel to another member. Removing the severable tongue 16 permits a panel 6 (Fig. 2), secured at right angles to the panel on which the fastener is mounted, to abut the flanges 22. <IMAGE>

Description

SPECIFICATION Wall board fastener Field of invention.

The present invention relates generally to panelled wall constructions in which wall panels or boards are secured to studs on a wall frame and, more particularly, to clips which are impaled in the edge of the wall panel and which are directly secured to the studs of the frame.

Background to the invention.

The mounting of wall panels to wall frames can be accomplished in a number of ways.

Preferably, however, it is most desirable to secure the wall panels to the frame without marring the surface appearance of the wall panels and in a manner which does not require the use of a decorative cover over the joint of adjacent panels to hide the fastening devices. Accordingly, a number of panel mounting clips which secure the panels to the studs of the wall frame and which permit adjacent panels to be interlocked with respect to one another have been developed.

The first clip of this type is disclosed in U.S. Patent No. 3308590 to Ettore et al. The fastener of Ettore et al comprises a flat base portion having a hole therethrough so that the base portion can be mounted to a wall structure. The shoulder extends normally from one end of the base portion. A pair of flat legs extend outwardly from the shoulder and the legs are substantially coplanar with the base portion. Sharp pins extend outwardly from the top of the shoulder in the same direction as the legs but spaced apart from the parallel to the legs. The pins are embedded in the edge of a wall panel so that the shoulder abuts against the edge of the panel. Thus, the legs extend behind the rear surface of the wall panel while the base extends outwardly from the edge of the panel and can be secured to a stud in the wall structure.The Ettore et al clip has proven to be quite satisfactory for its intended purpose.

Another previously known fastener for mounting wall boards is disclosed in U.S.

Patent Nos. 4117644 and 4221095 to Weinar. Weinar discloses a fastener comprising a plate portion and a tongue portion extending from the centre of the plate portion in a coplanar arrangement. A web which extends substantially normal to the plate, supports an impaling flange adjacent each side of the tongue which extends outwardly from the top of the web in a spaced apart but parallel relationship to the plate portions. An elongated depression extends across the plate and tongue portions, and an elongated slot is disposed in the tongue portion of the depression. The Weinar clip suffers the disadvantage that the fastener can only be secured to a wall structure through the tongue portion. Thus, the fastener of Weinar is not suited for use in securing a wall board in the corner of a wall structure.

Furthermore, the side walls of the depression serve to strengthen the coplanar disposition of the tongue and plate portions so that modification of their coplanar relationship is extremely difficult.

Summary of the invention.

According to the invention, there is provided a wallboard fastener comprising a single piece of sheet material having a base portion, said base having a first aperture therethrough, a tongue portion extending outwardly from the coplanar with said base portion, said tongue portion having a second aperture therethrough, two first flanges, each first flange extending substantially perpendicularly to said base portion, one first flange disposed on each side of said tongue, and a second, impaling flange extending from each first flange in a plane parallel to but spaced from said base portion above said base portion.

When installed, the fastener is thus disposed behind the rear surface of the wall panel to be hung and can be secured to a stud member adjacent to or directly behind the wall panel to be mounted. In addition, the fastener includes segmented supporting ribs which strengthen the fastener against inadvertent deformation but which permit the tongue portion to be easily servered from the main body portion to permit the fastener to be used for mounting a wall panel in the corner of a wall structure. At the same time, these strengthening ribs serve to support the wall panels a slight distance away from the studs to which the panels are secured so that the head of the fastener used in installing the clip fits between the stud and the wall panel and the adjacent panels lie flush.

The fastener can comprise a sheet of material with a flat base portion having a tongue extending outwardly therefrom in a coplanar arrangement. A pair of flanges extend upwardly from the base portion and having impaling flanges extending outwardly from the top thereof in a spaced but parallel relationship to the base portion. Both the base and the tongue include apertures adapted to receive a fastener therethrough. A pair of elongated ribs may be aligned on opposing sides of each aperture. The ribs in the base portion are preferably spaced from the ribs in the tongue portion. Preferably, a short rib is disposed in the interspace between the ribs in the tongue section and the ribs in the base section, and is parallel to, but offset from the ribs of the tongue and base portions.

Thus, the present invention can provide a fastener which permits a wall board or panel to be secured to a stud behind the rear surface of the panel as well as to a stud adjacent to the wall panel being mounted.

Nevertheless, when it is desired to mount a wall panel in the corner of a wall structure, the tongue portion is removed from the base portion by severing the tongue from the base intermediate the ribs. Accordingly, the aperture in the base portion receives the fastener therethrough and thus secures the wall panel engaged by the impaling flanges to a stud in the corner of the wall structure.

Brief description of the drawings.

The present invention will be more clearly understood by reference to the following detailed description when read in conjunction with the acompanying drawing in which like reference characters refer to like parts throughout the several views and in which: Figure 1 is a perspective view of a fastener of the present invention; Figure 2 is a perspective view of a fastener installed on a wall panel which is secured at the corner of a wall structure; and Figure 3 is a perspective view of the fasteners of the present invention as secured to adjacent wall panels.

Detailed description of the drawings.

Referring first to Fig. 1, a fastener 10 according to the present invention is thereshown comprising a sheet material 1 2 of such as metal. The sheet 12 includes the base portion 14 and a coplanar elongated tongue portion 1 6 extending outwardly from the base portion 14. Each of the portions 14 and 1 6 are provided with a substantially centrally located aperture 1 8 and 20, respectively.

Raised flanges 22 extend outwardly substan- tially normal to the plane of the base 14 at one edge of the base adjacent each side of the tongue 16. Each flange 22 supports an impaling flange 24. Each impaling flange 24 extends outwardly above the base section 14 in a substantially parallel but spaced apart relationship.

Still referring to Fig. 1 a pair of ribs 28 are aligned along opposing sides of the aperture 1 8. The ribs extend upwardly out of the plane of the base section 14 toward the impaling flanges 24. Preferably, the ribs are formed by punching or depressing portions of the plate section 14.

Similarly, the tongue section 1 6 includes a pair of ribs 30 disposed on opposite sides of the aperture 20. As shown in Fig. 1, the ribs 30 are aligned along the peripheral sides of the tongue 1 6 and in the embodiment shown are aligned with the ribs 28 in base section.

Nevertheless, the ribs 30 are spaced apart from the ribs 28 so as to provide a substantially flat portion therebetween for a reason to be discussed in detail hereinafter.

As also shown in Fig. 1, the fastener 10 preferably includes a further strengthening rib 32 extending across the junction between the base section 14 and the tongue section 1 6.

The intermediate rib 32 is spaced apart from the ribs 28 and 30 and preferably is located substantially with in the interspace between the ribs 28 and 30.

As best shown in Fig. 3, the fastener 10 of the present invention typically provides an interlocking connection between adjacent wall panels 40 and 42. A first fastener 10 is secured to the panel 40 by embedding flanges 24 into an edge 41 of the panel 40 so that the base portion 14 extends behind the rear surface of the panel 40. Additional fasteners 10 are mounted to the edge 41 in a similar fashion in a spaced apart arrangement (not shown) which is a well known arrangement. A fastner, such as a screw 50, is then installed through the aperture 20 in one or more of the installed fasteners 10 to secure the wall panel 40 to a stud 45 of a wall structure.

A plurality of fasteners 10 are then secured to the edge 43 of panel 42 by impaling the flanges 24 in the edge 43 of the panel. A plurality of such fasteners 10 are secured along the edge 43 in a spaced arrangement which is offset from the arrangement of fasteners positioned along the edge 42 of panel 40. The tongue section 1 6 of the fasteners secured to the edge 43 of panel 42 is then slid behind the panel 40 to secure the panel against the wall structure in lateral abutment with the first wall panel 40.

It can be seen that the ribs 28 and 30 press against the rear surface of the panels 40 and 42 so that the panels are spaced slightly from the stud 45. Thus, these ribs effect a counterbore for the head of the fastener 50 and thus, permit the front surfaces of the panels 40 and 42 to remain flush. The central rib 32 serves to retain the coplanar relationship of the tongue 1 6 with respect to the base portion 14 while the panel 42 is being slid into position with respect to the mounted panel 40. In addition, it will be understood that when the fasteners 10 are installed on a wall panel prior to shipment of the panels to a construction site, the central rib 32 serves to prevent inadvertent deformation of the tongue 1 6 with respect to the base 14 while the panels are being handled and transported.

Referring now to Fig. 2, it can be seen that the fastener 10 of the present invention is especially useful in connecting wall panels to a corner stud in a wall construction. As best shown in Fig. 2, the fastener 10 can be secured to a stud through the aperture 1 8 in the base section 14 of the fastener. When the stud is in the corner of the wall construction such as stud 60 shown in Fig. 2, tongue section 1 6 is removed from the fastener 10 so that the other panel 62 can abut against the flanges 22 of the fasteners which are entrained in the edge of the wall panel 64.

Removal of the tongue 1 6 is facilitated by the separation between strengthening ribs 28 and 30. When the tongue section 1 6 is removed, the offset strengthening rib 32 is no longer necessary. Since it is offset from the ribs 28, the fastener 10 can easily be sliced or broken through the interspace between the ribs 28 and 32 substantially as shown by the mark 66 in Fig. 2. Since the ribs 28 are not deformed or affected by the cut in the interspace between the ribs 28 and 32, they still serve to provide the proper space between the stud 60 and the panel 64 and provide a clearance space for the head of the fastener 50.

It should also be understood that the strengthening rib 32 can be made to terminate at a point substantially aligned with the flanges 22 of bracket 10 so that the tongue portion 1 6 can be bent normal to the base portion 14 without requiring actual cutting of the fastener 10. In any event, it will be understood that the fastener 10 of the present invention provides a handy means for mounting wall panels to a wall frame in a manner which does not deface the exposed surfaces of the wall panels. At the same time, they provide means for securely interlocking adjacent wall panels secured to a wall structure.

In addition, the ribs provide strength to the structure as well as a means for providing a clearance space for the head of a fastener between the stud and wall panel. The spacing between the ribs enables the tongue to be removed without deforming the rib structures.

Moreover, unlike previously known wall board fasteners, the fasteners can be secured to a stud through its base portion which extends behind the panel to be mounted. A combination of these features provides a clip which is especially advantageous for use in securing wall panels to a stud in a corner of a wall construction.
