SLIDE FASTENER Application filed November 17, 1931. Serial No. 575,677. I
This invention relates to slide fasteners or fastener slides, and particularly, to that type which is provided with transverse slots for the reception of a belt or strap, and whlch carries a snap fastener socket designed to separably engage a cooperating snap fastener stud, in order to hold the strap carrying the slide to another article carrying said cooperating element.
My invention contemplates the provislon of a simple and efficient one-piece socket fastener slide adapted to be made of asmgle piece of sheet metal and thereby suitable for economical quantity production. i
The various objects of my invention will be clear from the description which follows, and from the drawings, in which Fig. 1 is a rear elevatlonal view of a socket slide embodying my invention and provlded with spaced resilient fingers.
Fig. 2 is a section of the same, taken on the line 22 of Fig. 1.
Fig. 3 is a rear elevational view of another form of my new socket slide showing incl ned prongs thereon, and
Fig. 4 is a horizontal section of the same, taken on the line 4-4 of Fig. 3.
In that practical embodiment of my invention whichI have illustrated by way of example, I have shown fastener slides designed to be formed entirely of a single piece of sheet metal. Referring to Figs. 1 and 2, the slide member 200 is provided with the spaced transverse slots 41 and 42. One of the edgesof each of said slots may have suitable prongs as 201 projecting therefrom in the proper position to engage a belt or strap passed through the slots '41 and 42.
It will be understood, however, that the prongs illustrated in Figs. 1 to 4 inclusive may be entirely omitted to provide straight edges on the sides of the respective slots 41 and 42 or that prongs may be otherwise arranged as is shown, for example, in my prior Patent No. 1,828,256, dated October th, 1931.
' Between said slots, and preferably centrally of the slide member and on the substantially fiat portion thereof, the material of the '204. The cuts may be of any suitable shape,
guard 203 serves the purpose not only of sl1de member is pressed laterally outwardly to form the socket guard 203. I Said guard comprises the substantially rigid, continuous outstanding wall 204, and the apertured wall 205 bent inwardly therefrom and provided with the aperture 206.
I prefer, as shown, to form the resilient socket from the material of the slide member 200, so that said socket is integral with the slide member. This I do by making a series of cuts in the slide member and bending inwardly the material between the cuts to form the resilient fingers 207, which overhangslightly inwardly theperipheral wall of the aperture 206, but which do not touch the wall but as shown, I have used a pair of parallel cuts 208 and 209 joined by'a third cut 210 joining the outerextremitiesof the parallel cuts 208 and 209 and substantially at right angles thereto. A series of such cuts 208, 209, and 210 may be made at spaced intervals in the slide member between the socket guard and the slots ,41, 42 and the edges of the slide member. The number ofsets of cuts in said series may be greatly varied, as will be readily understood. to form the desired number of resilient fingers 207. It will be noted from Fig. 1 that the cuts 211 and 212 extend up to the transverse slot 41, as illustrated, but this is not necessarily so sincethe lengths of the cuts need be only suflicient to form said fingers 207. The extremities 213 of said fingers are curved asshown in Fig. 2, upwardlyand' inwardly so as to separablyengage a stud passed through the opening 214 between said fingers and to resist the disengagement of said stud therefrom, the fingers yielding radially inwardly on the passage of the stud an insufficient amount to reach the wall 204.
, It will be understood that the greater the number of fingers 207,'theless needbe the width of the openings 215 formed in the slide member by the removal of'material between cuts to form said fingers. It will further be 9 understood that the fingers 207 are the proper I shape to snap into engagement with the neck of a stud passed either through the opening 206 or through the opening 214. The socket assisting to position the stud by means of the wall of the aperture 206 but also serves the additional function of protecting the resilient fingers 207 against damage and injury by accidental excessive pressure which may be put upon said fingers as for example, should the slide be dropped and should one accidentally step upon it. 7
As illustrated in Fig. 3, the one-piece slide 220 is provided with the transverse spaced slots 41 and 42 for the reception of a strap and'with suitable prongs as 221, if desired. Said prongs may be bent somewhat laterally of the slidemember, as illustrated in Fig. 4, or they may be entirely omitted, as may be the prongs 201 of Fig. 1. i
The combined stud and socket member 56 is pressed out laterally from the, central preferably fiat portion of the slide member 220 to provide an aperture 57 in said slide memher and to provide an outstanding continuous and substantially rigid wall 58 terminating in resilient fingers 59. Each of said fingers terminates in a free end in inwardly spaced relation to the wall and isbent to subtend an angle of less than 180, said fingers providing an aperture 60. The fingers are made resilient by means of the spaced slits or slots 61 and are free to yield radially outwardly without touching the wall 58. The fingers 59 at the end of said wall may resiliently engage a well known cooperating resilient or non-resilient stud passed through the apertime 60 or through the aperture 57, while the outermost surface 62 of said well 58 may engage any well known resilient or non-resilient socket.
A stud may be passed either through-the opening 57 of the slide member 220 or through the aperture 60. In either case, the resilient fingers 59 snap into engagement with the neck of the stud and resist withdrawal thereof. This constructionrforms a simple and effective resilient fastenerelementwhich may be used either as a socket or as a stud and a whole may be formed of a single piece of sheet material to provide a simple and'economical but eflicient fastener slide. a 1 7 It will be seen that I have provided simple and efficient means for securing a strap, that it can be economically produced in large quantities from a single piece of sheetmaterial, and that I have produced a structure well designed to meet the severe requirements of practical use.
