FASTENING MEANS FOR WALL PANELS Filed June 13, 1955 rpm INVENTOR 'jll-z z'll Z alder ATTORNEY United States Patent() FASTENING MEANS FOR WALL PANELS Merill E. Rader, Columbus, Ghio Application July 13, 1955, Serial No. 521,802

2 Claims. (Cl. 20--74) This invention relates to the mounting and securing of relatively rigid preformed wall panels in operative positions of application upon, or in connection with, associated building wall frame members.

It is an object of the invention to provide a novel assembly composed of interconnected, sheet-metal mounting and fastening strips formed for ready connection with associated frame members of a building wall and with each other, whereby to secure in a firmly held and concealed manner adjoining marginal portions of a plurality of related wall panels.

Another object is to provide sheet metal fastening strips formed for secure clamping engagement with adjacent margins of a plurality of rigid wall panels, and wherein the exposed surfaces of the strips are so formed as to present an attractive appearance and one in which their mechanical panel-holding characteristics are largely concealed.

A further object is to provide improved wall panel mounting and securing means composed of channelshaped, interfitting, base and clamping strips between which adjoining portions of the marginal edges of associated wall panels are received and held, the strips including spaced webs through which fastening devices are passed in securing the strips to an underlying wall-frame member, the spaced webs providing for relative movement between the base and clamping strips in enabling the latter in applying clamping forces to panels arranged between the same.

An additional object is to provide the channel-shaped clamping strip of such a wall-panel-mounting assembly with a removable cover strip, which, when in its position of operative association with the clamping strip, provides smooth, flush, exposed surfaces of inviting appearance between adjacent panels, at the same time concealing the internal structure of the clamping strip.

Certain practical embodiments of the invention are illustrated in the accompanying drawing, and wherein:

Fig. 1 is a horizontal, transverse cross-sectional view, extended into a perspective showing, of a preferred form of my improved wall-panel-mounting and retaining means;

Fig. 2 is a similar view disclosing the clamping strip of said means by itself;

Fig. 3 is a corresponding view of the cover strip;

Fig. 4 is a detail perspective view of a base strip or member utilized in the means of the present invention;

Fig. 5 is a detail horizontal sectional view of a modified form of the invention disclosing its construction when a base strip or member is not utilized;

Fig. 6 is a similar view disclosing a still further modified form.

Referring to the disclosure of the structural details of the wall-panel-mounting and retaining means of the present invention as disclosed in the specific form thereof illustrated in Figs. 1 through 4 of the drawing, the numeral 10 designates the base strip or member of said means, the numeral 11 the clamping or panel-retaining strip thereof, and the numeral 12 the removable cover strip or plate 2,803,858 Patented Aug. 27, 1957 for the retaining strip. The base strip or member 10 may comprise an elongated, strip-like body coextensive in length with the clamping strip or the cover plate, or, as shown in Fig. 4, it may possess the form of a relatively short bracket, requiring the use of a plurality of the same in aligned spaced order for cooperation with each associated clamping strip, as will be readily understood.

Each of the strips 10, 11 and 12 is composed of a suitably rigid sheet material such as mild or stainless steel or various other ferrous compositions well known in the building industry, such sheet materials being rolled or otherwise shaped to desired configuration, and included therewith is the use of aluminum-containing or other lightweight metallic extrusions, or one or more of the so-called plastics.

As here shown, however, each base member or strip includes a fiat web 13 which terminates in spaced, outwardly directed, parallel side arms 14 arranged in perpendicular order to said web and which at the outer extremities thereof terminate in outwardly and laterally directed panel-seating extensions 15. Preferably, through the use of screws, or other equivalent fastening devices indicated at 16, the Webs 13 of the base members are stationarily secured in direct engagement with adjoining faces of wallframe-forming members 17, such as conventional frame studding, hereinafter referred to as a stud.

Adapted to be seated on and in direct contact with the extensions 15 of the base members are the inner marginal portions of a pair of substantially rigid wall panels 18.

To hold these panels in securely seated relationship with the base members or strips 10, each clamping strip is formed to possess a cross-ectional configuration corresponding generally to that of the associated base member or strip, thus enabling the body of the clamping strip to enter and be telescopingly received in the open channel 19 formed by each base member.

To this end, each clamping strip is shaped to provide a web 20 which terminates in outwardly directed, relatively spaced, parallel, side flanges 21, the latter, in'turn, terminating in outturned panel-engaging extensions 22. These latter extensions are preferably each composed of a double thickness of the sheet material from which the clamping strip is formed, so that the extensions possess rigidity and body, enabling the same to be drawn into and maintained in close-fitting, non-undulating, filat contact with the outer surfaces of the marginal regions of the panels 18, whereby the latter may be securely clamped between the extensions 15 and 22 of the base and panel- retaining strips 10 and 11, respectively.

In attaining such clamping of the wall panels, the webs 20 of the strips 11 are formed with openings 23 through which pass the shanks of headed screws 24, or other equivalent fastening means. Preferably, the screws 24 are arranged in pairs, as shown in Fig. l, in order to be disposed on opposite sides of the centrally disposed base member screws 16. The shanks of the screws 24 may, also, pass through aligned openings 25 formed in the base member or strip 10. By tightening the screws 24,. the flanges or extensions 22 are drawn into firm holding contact with the wall panels. It will be noted that the webs 13 and 20 of the strips 10 and 11, respectively, are maintained in spaced relation, so that the clamping action of the strips 11 will not be in any way hampered or curtailed.

To impart a finished and attractive appearance to these mounting strips when viewed from within a room containing the same on its walls, use is made of the cover strips or plates 12. Each of the latter includes a fiat Web 26 which terminates at its ends in spaced, parallel, inturned, resilient, locking flanges 27. These flanges are received within the outwardly opening channel 28 of the clamping strip 11, the flanges 27 being provided with longitudinally extending rib formations 2, the latter receiving corresponding formations 30 integrally formed.

with the side flanges 21 of the clamping strips.

It will be evident that when the clamping strips 11 are mounted by the screws 24 on the studs 17 in association with the base strips 10 and Wall panels 18, the coverplates of strips 12 may be readily fastened in posi-' tion by forcing the resilient side flanges 27 into the channels 28 so that the rib formations 29 will flex over and snap behind the complemental rib formations 31) 18' are" spaced outwardly ffom the stud members 17 to provide air space separation of an effective character between the panels andthe wall forming frame'work of a building. If such separation should not be deemed necessary in particular assemblies, thebase strip or mem ber, as shown in Fig. inlay be omitted and the panels 18allowed to seat directly on the stud member or mem hers. Otherwise, the construction is identical with that previously described. V v

In the arrangement shown in Fig. 6, virtually the same construction shown in Fig. 1 is employed, the only difference residing in extending the bearing or surface area 31 present on the; outer surfaces of the flanges 21 of the clamping strip 11 and which are disposed between the rib formations 30 of the flanges and the webs 20 thereof. This increased surface area is desirable in certain instances in that it precludes any tendency on the part of the clamping strip to rock or assume a cocked position in the channe1 28 when the screws 24 are being inserted and tightened.

Various other modifications may be made in the construction of the devices of the present invention beyond those here illustrated, and I therefore reserve the right to employ all such variations which may be said to fall fairly within the sco e of the claims.
