I

- An object of my inventionis'the provisionof a one-piece fastener member havinga basewith article-engaging means'extending on One side of the base and support-engaging means extending on the other side; Theinvention relates pare ticularly to the construction of the support-engaging meanswhich are of simple andinexpensive form comprising a hook-like element for engagingone-side wall of aplate opening and a flat lugdisposed entirely onone side of the base and' designed to be-deformed by-a -suitable-tool to I lock behind the plate adjacent a side wall of the plate opening opposite'that engaged bythe hook-like element. While fastener members are known in the art providing a hook-like element and a deforming element; theseflare relatively more complicated in design and more-expensive to tool; -A fastener of the present invention is very simple in construction:yet capab1e ofefficient docking attachment toa supporting-plate;

Referring to the-drawing whichI have illustrated in my preferred embodiment of my invention: I

Fig. 2 is a section 'takenaiong' the line 2-2 of Fig.1 and showingthe method by whihfthe fastener member is secured" to a supporting panel;

Fig. 5 is a side view of the tool preferably used to secure the fastener member to a supporting panel; and

Fig. 6 is a section taken on the line 6-6 of Fig. 5.

The fastener member I as shown in the drawing is formed of one-piece relatively soft metal such as cold rolled steel and provides a base portion 2. Article-gripping elements extend from the base portion on one side thereof and comprise in my preferred form an angularly bent a fastener device for elemefitfip'rdjectmg" out or the plane of the base at one endthreof and 'a 'camming' element 4 at an'pppositefend of the hasef'rom thefelefiient The

elements

It is understood that I do not wish to limitiny invention tofthis 'forhi of articleattacliing means because 'the fastener 'is' capable ofproviding other constructions without departing fron'ith'e spirit of theinventior'i f Thesupport-ngagiiig'ineans of the fastener member which" are adapte to be disposed thrcsugii'arectanguiartpenmg H "of the supporting panel 6 to engage se'cii'rely'the 'supportcomprise "a hook elem nt .1 2 and a" deformable lock- Big element in thel'ioriii ofa'lug l3 which is spaced llaterally'from he "element l2; Thehook aement I2 "is struck iofii"the materia1 of'the base'iiand pr""ects outwardlyfrom the base on the side" away: hem "the article-attaching elements? and"4 atianangle offabout 45 degrees with respect tofthewa's'e 2; [The "lug shaped locking'e'lein'ent f3 is also strueknom thematerial of thebase and extends foutwardlyf'r'om the base ontnesame side as the hook "element [2 at an anglewh "napproachs degrees with respect to the basel"The lugeleinent l'3which is formed from the relatively soft material of the fastener is deformable so as to be bent along a transverse line disposed at a point spaced from the base a distance substantially equal to the thickness of the supporting panel 6. In order to insure that the lug bends at points substantially along the aforesaid line, a stiffening rib I4 is provided on the lug which extends from the outermost free end of the lug to a point substantially adjacent the line along which the lug is designed to bend.

In securing the fastener member to the supporting panel 6 the attaching elements I 2 and I 3 are inserted through the opening ll of the panel so as to be disposed with the hook element I2 engaging a corner wall I5 of the opening I I and the lug element I3 extending through the opening substantially adjacent the opposite wall I6. Next, a deforming tool I1 is moved through the opening I8 of the base 2 from which material was taken to form the lug I3. The tool H has a body I9 providing an abutment 20 adapted to engage the upper side of the base 2 and a deforming portion 2| which extends from the body 20 through the opening I8 of the base. The deforming portion 2| provides a narrow shank 22 having a laterally extending foot portion 23 at its end. In operation of the tool to lock the fastener to the supporting panel, the tool is disposed in initial position with the foot portion in substantially parallel adjacent relation to the lug element I3 as shown in Fig. 2. Then, the tool is rotated in a counterclockwise direction viewing Fig. 2 as a result of which the foot 23 presses the lug element I3 outwardly and upwardly so that it takes a position substantially as shown in Fig. 3 in generally parallel relation to the supporting panel with its outer end 24 in substantial engagement with the lower surface 25 of the panel. As a result of this deforming action the hook element I2 and the deformed lug I3 cooperate to secure the fastener firmly to the panel. It will be seen that the attaching method hereinabove described utilizes attaching elements which are very simple in construction and which require only a simple handoperated tool to effect a secure locking attachment.

Although I have illustrated and described a preferred embodiment of my invention, I do not wish to be limited thereby as the scope of the invention is best defined in the appended claims.

I claim:

1. A fastener device comprising a base portion having at least two spaced openings therein, said base portion having means on one face thereof for fastener engagement with a part to be secured by said fastener, and attaching means extending from the opposite face of said base for securing said fastener device to a supporting part having an aperture, said attaching means comprising a tongue cut from the material of said base portion and extending integrally from the side edge of one of said openings adjacent to the other of said openings, said tongue being disposed at an angle to said base portion in superposed relation to said one opening to provide a hook for engagement behind a supporting part through an aperture therein, and a second tongue out from the material of said base portion and extending integrally from the side edge of said other opening opposite the side edge thereof nearest said one opening and entirely beyond the same face of said base as said first tongue, a reinforcing rib formed in said second tongue extending longitudinally thereof and terminating short of the junction of said tongue with said base, said second tongue extending substantially normal to said base to permit it to enter an aperture in a support adjacent one edge of such aperture while said first tongue is hooked over an opposite edge of such an aperture, said second tongue being adapted upon such insertion to be bent upon a transverse line to underlie such a support at such one edge.

2. A fastener installation including a supporting panel having an aperture and a fastener device comprising a base portion having at least two openings therein, said base portion having means on one face thereof for fastener engagement with a part to be secured by said fastener and attaching means extending from the opposite face of said base securing said fastener device to said supporting panel, said attaching means comprising a tongue out from the material of said base portion and extending integrally from the side edge of one of said openings adjacent to the other of said openings, said tongue being disposed at an angle to said base portion in superposed relation to said one opening to provide a hook for engagement behind said supporting panel through the aperture therein, and a second tongue out from the material of said base portion and extending integrally from the side edge of said other opening opposite the side edge thereof nearest said one opening into the aperture of said supporting panel adjacent an opposite edge thereof, a reinforcing rib formed in said second tongue extending longitudinally thereof and terminating short of the junction of said tongue with said base, said second tongue prior to assembly of said fastener device with said panel extending substantially normal to said base to permit it to be inserted into the aperture in the support panel adjacent said opposite edge of said aperture while said first tongue is hooked over said one edge of said aperture, said second tongue upon such insertion being bent upon a transverse line to underlie said support panel adjacent said opposite edge thereof.
