2 Claims.
This invention relates to improvements in snap fastener installations of the type including a stud element aflixed to one sheet of material and a cooperating socket element aflixed to anas other sheet; and in its more particular aspects to improvements in the construction of and manner of attaching a stud element to its supporting sheet.
The general object of the invention is to provide a one piece stud element which may be attached to a supporting sheet of flexible material without the use of a cooperating Washer, or comparable member, by having certain parts of the stud so formed that they may be folded disposed fingers adapted to cooperate with a preformed flange in engaging the sheet of material therebetween.
The full nature of the present invention, and
go further objects and advantages thereof, will be more apparent from the following description when read in connection with the accompanying drawing, in which Figure 1 is a perspective view of a one piece stud element constructed in accordance with my invention;
Fig. 2 is a sectional view of the element shown in Fig. 1, and a sheet of material to which the element is to be attached, both disposed between a pair of cooperating press elements;
Fig. 3 is a perspectiveview of the stud element of Fig. 2 after the latter has been attached to its supporting sheet of material;
Fig. 4 is a sectional view taken on the line 44 of Fig. 3.
Considering the drawing, wherein like refer-' head, and depending from the shoulders 13 of' the neck, and a base flange l4 extending radially from the base of the skirt.
The element is completed by the formation of a plurality of arcuately spaced slots l5, each extending from a point adjacent the base to a point adjacent the top of the skirt. The latter operation may be performed in any desired way, but preferably it is done by scoring the skirt at a plurality of points and then rolling the scored upon themselves to form a plurality of radially material l6 upwardly into the base of the neck, as shown most particularly in Figs. 2 and 4.
Such an element may be easily and readily. attached to a supporting sheet of material without the aid of cooperating washers or the like. Thus, as is shown in Fig. 2, the head and skirt are passed through a hole I! in the supporting sheet of material 18, and the assembly is placed upon a supporting anvil IQ of any appropriate press. Closing of the die 20 over the head and shoulders of the element will upset the skirt and fold the ribs 2| (intervening between each of the slots) upon themselves to form a plurality of radially extending fingers 22. The latter elements, in effect, form a second flange which is adapted to cooperate with the base flange M in securely engaging the surfaces of the sheet of material surrounding the hole I'l therein.
The ability of the flanges to engage the material securely is in large part dependent upon the area of the contacting surfaces. In the present instance there is no limitation upon the extent of these areas, for the base flange may have whatever dimensions are consistent with good practice; and by varying the length of the skirt, the fingers 22 may be made of a length adequate to cooperate with the flange. Thus, if the radial dimension of the base flange is a, then by making the length of the skirt substantially twice this dimension, plus I) (representing the thickness of the material l8), the flange formed by the fingers 22 will have the same radial dimensions as the base flange M.
A further feature contributing to the security of engagement between the element and its supporting sheet is to be found in the facts that the base flange may be solid, or at least have a solid edge, so as to be capable of resisting to a maximum degree any tendency of this flange to pull-through the hole in the material, and in that the cooperating fingers are of double thickness so as to resist any tendency to bend upwardly. Further, by scoring the skirt rather than relying upon uncontrolled splitting thereof during the upsetting operation, each of the fin- 4 gers will be of an equal width and each will have smooth edges contributing to the improved appearance, as well as avoiding any tendency of these edges to cut into the material.
Since certain changes may be made in the invention without in any way departing from the scope thereof, it is intended that the foregoing shall be construed in a descriptive rather than in a limiting sense.
What I claim is:
1. A one-piece stud member comprising a stud head having a contracted neck for cooperation with a socket member, a shoulder extending outward from the neck of the stud head, a cylindrical skirt of greater diameter than the stud head depending from the shoulder, and a continuous base flange extending radially outward from the lower end of the skirt, said skirt being approximately twice as long as the flange is wide and having a plurality of slots therein which extend for its full length and divide it into a circular series of relatively narrow ribs, such ribs being adapted to be folded outward upon themselves to provide a series of radially disposed fingers capable of compressing a supporting sheet between themselves and the continuous base flange.
2. A one-piece stud member comprising a stud head having a contracted neck for cooperation with a socket member, a shoulder extending outward from the neck of the stud head, a cylindrical skirt of greater diameter than the stud head depending from the shoulder, and a continuous base flange extending radially outward from the lower end of the skirt, said skirt being approximately twice as long as the flange is wide and having a plurality of slots therein extending for its full length with the removed material rolled up in the skirt under the shoulder and stud head, such slots dividing the skirt into a circular series of narrow ribs adapted to be folded outward upon themselves to provide a plurality of radially disposed fingers capable of compressing a supporting sheet between themselves and the continuous base flange.
