FASTENER.
This invention aims to provide an. im proved separable fastener, particularly, though not exclusively, useful in securing carpets and the like to floors.
In the drawings, which illustrate a prothe wall 3 (Fig. 5), thereby permitting the ferred embodiment of my invention Figure 1 is a plan view of one corner of a carpet showing an underlying fastener in dotted lines; g
Fig. 2 is a sectionon the line 2-2 of Fig. 1, being partly in elevation;
Fig. 3 is a top plan view of the preferred form of socket;
Fig. 4 is a bottom View of the socket shown in Fig. 3;
Fig. 5 is a section 011 the line 55 of Fig. 3; and
Fig. (3 is a section on the line 6-6 of Fig. 3.
Referring to the drawings and to the preferred form of my invention, 1 have shown a socket pressed from a single sheet of metal and presenting an outer upstanding cylindrical wall 1 having extending therefrom a plurality of attaching prongs 2, similar to those shown and described in my copending application Serial No. 687 ,7 53. p
A second or inner upstanding cylindrical wall 3 is' also provided and both walls are connected at their lower peripheries by a web 3, as best illustrated in Figs. 2 and i.
The inner wall 3 supports, at its upper periphery, a plurality of resilient fingers 4 between which are provided alternating short slots 5 and long slots 6, the purposes of which are more fully hereinafter described- The resilient fingers extend curvilinearlv downward from the upper periphery of the inner wall 3 to the plane of the web 3 and then upwardly to the plane of the upper periphery of the wall 3 where they termlnate to form a stud-receiving aperture 7 for reception of the head of a stud. These resilien fingers are provided at their free ends with. reversely bent neck-engaging portions 8 for cooperative engagement with the neck of a stud.
The short slots 5 and long slots 6 provide the plurality of resilient fingers 4 having lengthwise edges of unequal length so that they may flex upon substantially straight lines extending bet-ween the outer ends of the slots. These lines are located along such points in the socket as to permit the greatest flex of the fingers it being easier to flex the fingers on a Straight line between the slots than on a curved line as would be thecase if the slots were all terminated at the upper end of thewall 3. To accomplish the fore going results the slots 6 extend to the inner 7 wall 3 (Fig. 6) and the slots 5 fall short of resilient fingers 4 to flex uponsubstantially straightlines where themetal of the socket, has not, to any great extent, flowed or stretched, thereby providing fingers of maximum durability. The downward and upward curve of the resilient fingersgreatly in-n creases their strength as well as their length,
thus greatly decreasing the amount which the" h outer ends of the fingers must flex during engagement and disengagement of the stud. The socket may be attached to the carpet 9 by the attaching prongs 2, in much the same .manner as described in the aboveunentioned copending application.
The preferred form of stud, for use in connection with the above described socket, is formed from a single piece of metal turned or otherwise shaped in a suitable machine to present the usual head 10, shoulder 11, neck 12 located between the head and shoulder and a. relatively long shank or attaching portion 13' slightly tapered. The stud is preferably secured to the floor 14 of an automobile or the like, by forcing the attaching portion 13 into a hole '15 therein of approximately the same diameter as the small end of the attaching portion 13 of the stud. Thus the attaching portion of the stud is wedged into the hole 15 and is held therein by the friction between the wood and shank. To prevent driving the shoulder 11 of the stud into the wooden floor,
I have interposed a metal washer 16 between the shoulder 11 and the floor 14, which spreads out over sufficient area to prevent its being pressed into the floor: This type of stud is simple and inexpensive to manufacture and may be quickly and easily attached to the floor, and when attached it grips the side walls of the holeso tightly that it is capable of withstanding great upward strain exerted thereon; The surface of the, attachingportion 13 may, if necessary, be roughened slightly to increase the grip on the wall of the hole in the floor.
When the socket is engaged with the head of the stud, the curved resilient fingers present guiding surfaces which afford an unobstructed guiding surface for engaging the socket over the head of the stud so that engagement therewith may be efiected Very easily and quickly Without the necessity of accurate engagement of the head of the stud with the stud-receivingaperture asis necessary when the stud-engaglngifin-gers are not curved upwardly adjacent the Stud-receiving aperture. The reversely bent neck-engaging portions, being formed at the upper surface, do not obstruct the entrance of-the stud into the stud-receiving aperture as they do when presentedat the lower surfacesofthe resilient fingerf Thusthe socket herein illustrated may be guided over the head of the stud smoothly, and the resilient fingers will flex upwardly, without interference fromthe carpet, to permit passage of thehea-d throug h the stud-receivingaperture 7 (F ig. 2) anden gagement of the'neck 12 of the stud by the I neck engaging portions 8 of the resilient i p o fingers I r VVhile'I h'a veshown and described av preferred embodiment of my invention, it will aperture, a web surrounding said aperture and divided by a series of alternating short and long slots to provide a series of stud-engaging fingers surrounding said aperture,
said fingers having their free ends terminatingin a'commonplane 21d]'2111l3 to said aper tureso-that the tree endsof all of said fingers mayniake fasteningengagement with a neck of a cooperating stud and each of the fingers of the series I sr'u'roundlng the studreceivin a erture havilm one ilelwtllwise b b b edge shorter than theother lengthwise edge as and for the purposes described. o
In testimony whereof, I have signedmy name to this specification. a
