Claims.

This invention relates to building structures and particularly to wall and ceiling constructions of the built-up panel type.

In the construction of buildings of all types, including homes as well as business and commercial structures, there is an increasing tendency to employ, as wall and ceiling coverings, assemblages of panels instead of plaster, stucco, and the like. Panels made of fiber insulatin board are extensively used for that purpose. These panels generally include the types known in the trade as tile. and plank. The designation tile is generally used to indicate relatively small size sections, including square sections, such as 12" x 12", 16" x 16", and rectangular sections such as 16" x 32" and 24" x 48". The designation plank is generally used to indicate relatively elongated rectangular panels which are usually furnished in lengths of 6' to 12' and in widths of 8" to 16". By the use of these panels, ornamental efiects of variable character can be easily realized, and sound absorbing materials employed over specified areas. Panels made of gypsum or like materials may be similarly utilized, particularly where fireproofmg is desired. In addition, savings are generally realized when a wall or ceiling covering of the panel type is employed, the cost of installation being reduced, in some cases to a substantial extent.

The present invention has for its purpose to provide an improved panel attachment means which is particularly suitable for use in the assembly of wall and ceiling coverings of the type in which the panels are formed with tongues and corresponding grooves, ship-laps, kerfs or a other well-known mating iormations on or in their opposite edges. When the tongue-andgroove type of panels are employed, this invention contemplates the provision of attachment elements embodying a panel-engaging portion which is adapted to be received within the groove formed in one edge of one panel and to extend around the tongue projecting from the edge of the adjacent panel. F In the case of other panel edge formations, such as the ship-lap and/or kerfed types, the panel-engaging portion of the element is modified so as to cooperate with the mating portions at the edges of adjacent panels.

More particularly, it is an object of the invention to provide a novel attaching element adapted to secure panels directly to a supporting structure without requiring the use of intermediate iurring and to maintain an assembly of panel coverings in a position relative to the supporting structure so that the exposed surfaces of the all panels are retained in a common level plane, independent of any unevenness or limited dimensional variations of the supporting structure. This feature of the invention is obtained by reason of the fact that the attaching element is designed for attachment directly to a surface of the supporting structure which is in a plane substantially at right angles to the plane of the panel covering, thereby eliminating the requirement for the use of furring. Also, the construction of the attaching element is such that the retention of the panels in a common plane is not affected by relative movements of adjacent panels under the influence of moisture absorption or the like.

As will be apparent from the drawing and from the more detailed description herebelow, the attachment elements provided by my invention may be secured directly to a beam, joist or stud of the supporting structure at intervals therealong in order that each of the panels may be engaged by at least one attaching element along each of a pair of its opposite edges. It will also be apparent that the attachment elements do not interfere with the engagement of adjacent panels when interlocking or interfitting panel edges are employed and, when installed, are wholly invisible from the room side of the completed panel covering. Moreover, they are more easily applied in use, less expensive, lighter in weight, and smaller in bulk than most types of panel securing devices heretofore designed or suggested. They are particularly adapted for attaching panels to an overhead supporting structure, but may be advantageously employed with a vertically disposed supporting structure.

The invention likewise contemplates the use, with my novel panel attachment elements, of panel edge stiiiening members in the event that panels with tongue-and-groove type edges are employed which do not have sumcient natural stiffness or rigidity to retain their shapes when suspended at widely spaced points, particularly those panels which have a tendency to sag over a period of time when attached to overhead supporting structures. The panel edge stiffening means are particularly advantageous when used along edges intersecting a joint between adjacent panels and in position to bridge such joint. Each stiffening member is in the form of an elongated channel-shaped element so dimensioned that it may be placed within the groove formed in an edge of one panel and receive the tongue formed on an edge of an adjacent panel, thus lying hidden .from view after being inserted, but'nevering the application of an attachment element of the present invention for attaching a panel covering to the supporting structure;

Referring now to the drawing, a portion of a ceiling construction is shown, comprising a supporting structure and a covering of inter-engaged panels which are attached to the supporting structure by means of attachment elements of the present invention. As best shown in Fig. 4, the

overhead supporting structure comprises horizontally spaced wood beams iii having their broad faces I I extending in substantially parallel vertical planes. The covering panels i5 may be in the form of fiber insulating board and may have a decorative finish for exposure within a room. These panels are cut in relatively short, square or rectangular, sections designated as tile. each having two adjoining edges provided with tongues 12 and the two opposite edges provided with mating grooves i3 for interlocking or interfitting engagement with the tongues of adjacent panels. 7 Such tongue-and-groove interlocking relationship between adjacent panels i5 is indicated clearly in the drawing and the attaching means which I have provided comprise a plurality of devices, such as indicated at 28, for

securing the panels to and suspending them'from the overhead structure in a level horizontal plane.

As seen. most clearly in Figs. 1 and 2, each such attaching device 28 comprises a panel-engaging portion 2! in the form of a channel and a relatively elongated shank 22, extending transversely of the channel in a plane at a right angle to the plane ofv the mouth of the channel. The shankZZ is, provided with one or more perfora tions 23 for securing the attaching device to a vertical face H of a beam, by nailingor the like. The gauge of the comparatively stiif but bendable metal employed; in the fabrication of the attachment element 20 is sufficiently thin to enable the channel portion 2% of this element to be positioned between thetongue 12 of one panel i5 and the groove i3 of the adjacent panel, the outer surfaces of the channel 2! closely fitting against the inner walls of the groov and the inner surfaces thereof closely engaging the outer surfaces of the tongue, as shown in Fig. 1. Although the channel 2| occupies some space, the panels i5 are usually fabricated of material which is compressible or deformable to a certain extent, and no di-fiiculty will be encountered in inserting the tongue [2 of one panel into the groove [3 of the adjacent panel and maintaining the slidable inter-engagement therebetween, even when a plurality'of securing devices have previously been applied either to the tongue of one or within the groove of the other. It is noteworthy that, with proper dimensioning of the channel portion according to the cross-sectional size and shape of the tongues and grooves formed on the edges of the panels, the attaching element is completely invisible through the V-shaped grooves M with which the exposed edges of the panels are usually provided. The blank from which the element at is formed is originally of substantially the same width from one end to the other, and the shank 22 is formed by doubling the metal longitudinally upon itself as indicated at 24 and then providing one or more openings 23 in this portion of the element for the nails or other fastening elements by which it is secured to a face ll of the beam [8. g

In Fig. 3 there is illustrated a modified form of attachment element for attaching tongue-andgroove mating panels to an overhead supporting structure in the manner described above. In this embodiment, the attachment element 30 comprises a channel portion 3| to fit within the groove of one panel and around the tongu of an adjacent inter-engaging panel edge, in. a manner similar to the portion 2! of the form of attachment element previously described. Th element 3!! has a transverselyextending portion or shank 32 bent or twisted adjacent the channel portion 3| until the head 33 of the shank lies in a plane at a right angleto the plane of the mouth of the channel portion. This permits the channel portion to be engaged with the tongues and grooves of the panels as described, while the head 33 may be secured to the face I I of the beam it by a nail or screw, such as indicated at 32.

In the erection of a panel suspension system utilizing the attaching elements described above, a plurality of these elements are fastened successively to the faces of the beams l0 'so that the lowermost surface of the channel portion of each element will lie in a common horizontal plane. Adjacent pairs of attaching elements fastened to each beam are spaced apart a distance equal to the corresponding dimension ofv a panel to be held by and suspended between the pair of elements. If the selected panel has a transverse dimension sufficient to span a number of adjacent beams, some economy in material and labor can be eifected by eliminating the use of attachment elements at every alternate beam without depriving the assembly of the required support.

Each of the elements 20 of Figs. 1 and 2 is secured to the beams 10 with only one nail or other fastening means driven through the upper perforation of the extending portion 22. The element 30 of Fig. 3 has a centrally located nailing perforation 34 in the head portion 33. Thus, in either embodiment a swinging movement of the elements around the nails as a pivot is permitted, thereby enabling the panels to have sufiicient clearance for positioning between a pair of the elements and engagement with the channel portions thereof. After the panels are thus engaged, they will be retained in a common plane without being effected by the relative movements of adjacent panels under the influence of moisture absorption or the like. If desired, however, the attachment elements may be fixed against further pivotal movement by driving nails or other fastening means through additional perforations provided on the extending portions, such as the lower perforation shown on the extension 22 of the element 20. Additional perforations may likewise be provided for this purpose adjacent either one or both opposed ends of the T-head 33 on the element 30.

A covering structure comprising a large number of panels may be adequately secured in position by the attaching elements of the forms above described, but in the event that these panels are of soft texture or to be secured to beams spaced apart at considerable distances such as to be likely to sag, the retention of the panels in a common plane may be insured by means of stiffening elements such as channel members 40. The channel members 40 are preferably of metal and of the same gauge as the channeled portions of the attachment elements, but are considerably longer. They may be applied at various locations and in Fig. 4 an opposing pair of them (one in dotted lines) is shown applied to the edges of the panels running at right angles to the beams and in a position to bridge and reinforce the joint between adjacent panels occurring intermediate the beams Hi. When so positioned, each elongated stiffening member 40 discourages sagging of the panels at points between the securing device and particularly at the joints between adjacent panels. Channel reinforcing members may also be employed along the edges of the panels which extend parallel to and intermediate the beams, and may be of suflicient length to extend substantially the entire distance along these edges, as shown in dotted lines at 4!. The channel reinforcing members may also serve to protect the relatively frangible panel edges from damage during shipment and storage by inserting the channels within the groove or applying them over the tongues of the panels at the factory prior to packing for storage or shipment.

The embodiment illustrated in Figs. 6 and 'l of the drawing may be employed with various types of panel edges, such as tongue-and-groove edges, straight butt-bevel edges or straight edges with intermediate horizontal kerfs or slits, or the shiplap edge arrangement shown in Fig. 6. As shown, the attaching element 50 comprises a shank portion which is Z-shaped in plan to provide oppositely extending off-set flanges 52 and 53. Either one of these off-set flanges may be employed for securing the element to a face ll of the beam ID, by means of nails or other fastening elements which pass through the perforations 54. The oppositely off-set flange serves as a reinforcing or stiffening member for the panels 65 when engaged with the panel-engaging portion 55 of the attaching element. The panelengaging portion 55 comprises a pair of spaced

wings

56 and 51 integrally connected with the shank by a connecting rib 58 and bent into a plane at right angles to the planes of the flanges 52, 53. The

wings

56, 51 extend on opposite sides of the connecting rib 58 and each of them terminates in pointed ends or

prongs

59, 60 and BI, 62. The pair of prongs 595l are adapted to be inserted into the kerf 66 or forced into the edge of one of the panels, as shown in Fig. 6, while the oppositely extending pair of prongs 60-62 together with the intermediate, integrally-connected plate 63, form a supporting or bearing surface which is disposed beneath the overhanging ship-lap 61 of the adjacent interfitting panel. Thus, it will be apparent that when the interfitting ship-lap panels 65 are engaged with the attaching element 50, the lower panel-engaging portion 55 of the attaching element will be disposed within the interfitting panel edges so as to be completely invisible through the V- shaped grooves 68 with which the exposed edges of the panels are usually provided.

The manner in which the Z-type attaching elements 50 are utilized in the erection of a panel covering system is the same as described in connection with the

fasteners

20 and 30. A plurality of these elements 50 are fastened successively to the vertical faces of beams so that the panelengaging portion 55 of each element will lie in a common level plane. Adjacent edges of adjacent panels underlying the beam will be engaged by the wings of the panel-engaging portions in the manner previously described, thus insuring the retention of the entire panel covering in a common level plane.

It will be observed that in each of the embodiments described, the panels are attached to the supporting structure by fastening elements formed so as to make possible the nailing or other securement of the fastening elements to a face of the supporting member such as a beam l 0 which is in a plane at right angles to the plane of the panel covering. Thus, my invention provides a panel attaching means that is economical and eificient in use, and one that will retain the panels composing the covering in a common level plane entirely independent of any unevenness or limited dimensional variations occurring in the supporting members. Moreover, the attachment elements of the present invention serve to fasten the panels to the supporting structure without the use of furring strips, thus eliminating the cost of the furring, since the fastening elements are fastened directly to faces I l of the beams Hi. It will also be apparent that these attachment elements may be employed according to the invention in the erection of panel coverings for vertical walls, as well as ceilings, since the elements may be attached to the vertical studs of the Wall supporting structure and the panels engaged with the elements in the same manner described above in connection with the beams or joists of the overhead supporting structure.
