F. M U LKA SLIDE FASTENER Dec. 25, 1956 Filed Dec. l5, 1950 United States Patent O SLIDE FASTENER Friedrich Mulka, Wewelsburg, near Paderborn, Germany Application December 13, 1950, Serial No. 200,663
Claims priority, application Germany December 13, 1949 Claims. (Cl. 24--205.1)
The present invention relates to a slide fastener and to a method for producing Vthe same.
In the prior slide fasteners the fastener elements are attached to the Stringer tapes either by being seated on and clamped to a ridge formed by the Stringer tape or by being embedded in elastic profiled strips of a plastic. Both kinds of fasteners are expensive to manufacture.
It is the object of the present invention to provide a slide fastener in which the fastener elements are securely attached to ordinary plain tapes consisting of any de- Sired material.
It is another object of the present invention to provide a slide fastener forming a sealed connection using ordinary plain tapes of any desired material.
According to the present invention the marginal zones of the tapes are folded so as to embrace the fastening elements which are firmly held in position within the 'folds by clamps embracing the folds from the outside.
The novel slide fastener is much cheaper since it does not depend on the use of special tapes provided with a ridge but can be combined with tapes of any desired material. Moreover it permits to obtain an air or water tight connection which also prevents the passage of dust.
Further features of the present invention will appear from the description of two preferred embodiments thereof illustrated in the accompanying drawings in Which- Fig. l is a plan view, partly shown in section, of the novel slide fastener, the section being taken along line 1-1 of Fig. 2,
Fig. 2 is the cross-section taken through the slide fastener rshown in Fig. l, said section being taken along line 2 2 of Fig. l,
Fig. 3 is a cross-section through one of the Stringer tapes of a modified embodiment of my invention, said section being taken along line 3-3 of Fig. 4, and
Fig. 4 is a partial section taken along line 4-4 of Fig. 3.
The two stringer tapes a and b which may consist of any desired textile or other pliable material are each provided with a row of fastener elements c, each such element being formed by a at member having an arrow head g at its outer end, a riveted head h at its other end and two hooks i between its ends. Each Stringer tape a forms a longitudinal fold of S-shaped cross-section, as will appear from Fig. 2. The fastener elements are inserted in the outer loop of the longitudinal fold their arrow heads projecting from the fold. The loop of the tape enclosing the fastener elements is embraced by outer U- shaped sheet-metal clamps d which press the material of the tape firmly upon the upper and lower faces of the fastener elements.
In the embodiment shown the ends of the fastening elements c extend through the tape a, or b respectively7 and through the clamp d and are riveted to form the heads h whereby the fastening elements, the tape a, or b respectively, and the clamp d are firmly united. If desired, the fastening elements, however, may be attached to the 2,775,0l2 Patented Dec. 25, 1956 f. ICC
clamps d by soldering, welding, cementing or by a pressing operation or a chemical fusing operation.
The customary slider e which serves to open and close the interlocking rows of fastener elements c embraces the clamps d as shown in Fig. 2. The lower arms of the clamps d have downwardly bent ends which in closed condition firmly press the tapes a and b one upon another thereby forming a sealed closure. As shown in Figs. 2 and 3, the clamps d have channel guidable cross-Sections, shown as generally rectangular herein, and the slider has channels for gnidingly cooperating therewith, thus aligning the heads g of each row of fastener elements with the spaces between the fold-embraced elements of .the other row during the closing of the fasteners. As shown in Figs. 2p, 3 and 4, the clamps d have terminal end portions facing the line of interengagement of the fastener elements and spaced from that line by distances less than the uncompressed thickness of the strips, andthe Strip material of each of the exposed tapes is of a thickness such that it projects slightly beyond said line of interengagement so that on closing of the fastener the tape materials are compressed together at both sides of the interengaged rows of fastener elements. With this arrangement normal lateral pull on the tapes tending to reduce the compression thereof at one side of the row of interengaged fasteners tends to increase the compression thereof at the other side of the row maintaining a tight Seal.
In addition to compressing against each other at both sides of the fastener, the material ofthe strips may be compressed against the line of interengagement of the fastener elements. Thus in the form shown, when the fastener is closed, the compressed material of the strips bears against Side faces of the fastener heads adjacent the line of interengagement that corresponds to the Vline of the base of the fastener head, shown as having a generally isosceles trapezoidal cross-section in Fig. 4.
The embodiment illustrated in Figs. 3 and 4 differs from that shown in Figs. 1 and 2 by the fact that the top faces and the bottom faces of the fastening elements 2 have indentations and that the clamps 1 have inner projections 3a which register with the indentations rso as to press the tape 3 into said indentations. Owing to this arrangement the material tof the tape 3 is firmly pressed into the indentations of the fastening elements 2 whereby the latter will be more firmly united with the tape 3 and with the clamps 1.
The term tape as used hereinabove and in the appended claims isV intended to include any piece of cloth having an edge to be fitted with a slide fastener. AS above mentioned, the tapes are planar and may consist of any desired material that, like cloth, is a flexible, compressible, and foldable, sheet-like material capable of bending to permit opening and closing of the fastener, and the term individual to means that each fastener element has its own attaching portion and clamping element, not shared with any other.
Preferably, the inner projections 3a of the clamps l are formed by indenting the clamp as shown at 4.
