' INVENTOR BY GEORGE C. BRUMLiK BURGESS. DINKLAGE & SPRUNG v 1 PRESS-THROUGH SELF-GRIPPING DEVICE'F BACKGROUND This is a continuation of application Ser. No. 126,709, filed'Mar. 22, 1971.
This invention relates to a penetrating multielement fastening device. More particularly, this invention relates to a fastening device for holding or attaching together sheet-like members which includes a gripping member, the gripping elements of which are adapted to penetrate and pass through the sheet-like articles and a receiving member in which the gripping element lodges and is retained or held therein.
Various self-gripping fasteners, particularly suitable for releasably fastening fabrics and the like are presently available. Typical of such fasteners are a selfgripping fastener assemblies presently marketed under the trademarks Velcro and Headlockl Velcro is in the form of pairs of fabric strips which are suitably secured to the opposing fabrics to be fastened together. The Velcro fastener comprises multiple rows of small vertically-extending open plastic loops secured to the outer surface of one of the matching strips while matching small plastic hooks are secured to the outer surface of the opposite strips. Thus, when the two opposing strips are press-contacted the hooks link with the opposing loops in an interlocking action, and when pulled apart with sufficient force,.the hooks disengage from their corresponding loops.
While the Velcro and Headlock fasteners provide an effective gripping action, the cost of manufacture thereof is relatively expensive.
More importantly, the presently available devices require a secondary process such as sewing, gluing, riveting, etc. for attachment.

The gripping elements used in the present invention are stiff or firm, needle-like members having barbs, hooks, truncated, cone-like bodies serrated grooves and the like. Gripping elements having a slightly rounded tip similar to the geometry of the tip of sewing needles for fabrics are suitable where the sheet to be held or fastened is a fibrous material. In the case of solid sheets such as plastic, paper, leather and the like, the gripping elements should have a sharp point and if necessary also one or more cutting edges similar to the cutting edges used on needles for sewing leather and the like. The gripping elements are preferably made of metal wire, glass filaments or hard plastics such as polyacetals, nylons, polyesters, melamine and the like.
Suitable gripping elements are shown in FIG. 3 of the drawing. Other suitable gripping elements are described in my issued patents, US. Pat. Nos. 3,494,006 and 3,522,637, which are incorporated herein by reference.
The gripping elements are mounted up-right in or on the base in such a manner that they resist deflection which would otherwise prevent them from piercing, penetrating or passing through a sheet to be held or fastened. Thus, the base can be flexible and the gripping elements interconnected to one another to provide the necessary stiffness. The base can also be stiff or rigid and the gripping elements firmly secured thereto.
The base can be made from any suitable rigid, semirigid, stiff or flexible sheet material such as paper, fabric, plastic, metal, glass and the like. The gripping members can be an integral part of the base or can be firmly attached thereto by suitable techniques such as mechanical interpenetratin or by using an adhesive, welding and similar techniques. Also the gripping elements can be inserted from the back or bottom of the base and held in place by a suitable stop such as is shown in my US. Pat. No. 3,494,006 mentioned previously.
The gripping elements can be of any size and diameter depending on the nature of the receiving member and the sheet materials to be fastened. Generally they have a diameter of from about 0.001 to about 0.05 inch. Basically, the gripping members should be long enough to penetrate or pass through the sheet members to be fastened and lodged in the receiving member. In addition they are preferably positioned in uniform parallel rows as shown in FIGS. 10-15 of the drawings. The gripping elements may be randomly positioned provided they are sufficiently far apart.
The receiving member used in the present invention can be made of any material which is sufficiently soft or porous to permit the gripping elements to penetrate and lodge or become retained thereby. The thickness of the receiving member depends on the nature and size of the gripping elements and generally falls within the range of about 0.002 to about 0.25 inch. Suitable receiving materials include woven and non-woven fabrics and felts, fibrous mats, metal or plastic mesh in one or more layers, foamed plastics, wood and other suitable materials which may be woven, knitted, molded or cast including carpet and carpet-like materials.
The backing member used in a preferred embodiment of the fastening device may be made of any material which is sufficiently tough to prevent the gripping elements from penetrating therethrough. Suitable backing materials include metals, plastics, leather and leather substitutes, wood and other suitable molded extruded or cast materials.
The fastening element of the present invention may be used to hold or fasten all types of sheet materials such as woven or non-woven fabrics, paper, leather, plastics, metals, mesh, perforated or expanded plastics or metals. In the case of rigid plastics or metals in perforated, mesh or expanded form, the gripping device of the present invention operates by passing through the perforations or openings in this sheet and then gripping the receiving member.
In addition to the button and zipper secondary fasteners shown in FIGS. 7 and 9 of the drawing, other suitable secondary fasteners include hooks, snaps, eyelets, holders, self-gripping devices and the like.
