12 Claims.
My invention relates to separable fasteners of the general class known as slide fasteners or "zippers. In nearly all of the fasteners of this type which have been on the market, the fastener elements are provided with jaws or arms which extend around the edge of the flexible stringer. An example of this type of fastener construction is shown in Patent No. 1,219,881 to Sundback. The interlockingportions of the fastener are only those portions which extend beyond the edges of the tapes or between the edges of the tapes when interlocked and which have interfltting projections andrecesses. The greater part of the fastener element is taken up by the jaws which extend over oraround the edges of the tapes. The structure of Marinsky Patent Reissue No. 18,406, dated April 5, 1932, is an example of a fastener in which a two ply tape has apertures through which the fastener elements project.
The fundamental object of my invention is to do away with the extending jaws or arms and make the fastener elements of only such size as necessary to carry the proper interlocking devices. This result is not accomplished by such a structure as shown in the Marinsky patent, because in that structure there are the equivalents of the extending jaws in the portions of the wires which extend around the cord. In carrying out my invention I preferably have flexible portions of the stringers themselves extending around the body of the fastener elements between the projections and recesses so that the elements can be arranged wholly between the edges of the ribbon-like stringers or tapes. In one embodiment of my invention the elements may be said to be woven intothe edge of the tape. In the accompanying drawing I have shown for purposes of illustration a preferred embodiment and a modification thereof. In the drawing:
Fig. 1 is a front view of a portion of a fastener t of fastener element;
Fig. 5 is a plan viewshowing a stringer with the modified form of elements; and
Flg. 6 is a cross-sectional view through the stringer showing the modified form of element.
In the fastener illustrated there are a pair of flexible stringers-hereinsingle ply fabric tapes fl. 5 and along the adjacent edges of the tapes are the fastener elementsxenerally designated 9.
shaped portions on the opposite stringer.
. each element are taken up by a concavity It) on one end and a convexity II on the other end,
which cooperate with and fit into correspondingly Each of the elements is of'generally cylindrical form and extends lengthwise in the same direction as the fastener. Each element is provided with flanges or shoulders l2, I3 which define a circumferential groove it between them extending around the middle portion of the fastener element. The elements in the interlocked position of the fastener are arranged wholly between the edges of the tapes and no portion extends over or around these edges corresponding to the gripping arms of the usual fastener element.
The elements are held in place by suitable holding means on the tape, preferably of a flexible nature and passing around the groove Id. In the embodiment illustrated thisholding means takes the form of bunched cross-threads which are extended laterally to project from the edge of the tape as. indicated at IS. in the weaving of these tapes the elements are held in place and the tape is woven with the cross-threads extend ing around the element as illustrated. One of these cross-thread extensions can be plainly seen at It in Fig. 2. A slider ll is mounted to slide on the flanges l2, 13 so that it embraces the extending portion Id of the cross-threads but is supported out of contact with them so thatv the flanges of the slider ,will not break the threads.
The slider may be of any convenient form and will not be further described except to say that it is actuated along the stringers by a pull tab l8.
In the modification illustrated in Figs. 4 and the elements it are also of the form generally resembling a cylinder but having one flat side 21B applications'where considerable strain is placed upon the slider in closing'the fastener.
The elements may be readily manufactured from metal or a suitable plastic material in any known manner. For example, they may be machined. or molded to shape. Their size and spacing on the tape may varied to suit conditions.
Where extreme flexibility and refinement are desired the elements may be made short and spaced close together but where there is required a cheaper fastener which need not be so flexible, the elements can be somewhat longer and correspondingly further apart.
The advantages of the novel form of fastener herein disclosed will be readily apparent from the above description and the accompanying drawing. The line of fastener member material which is visible along the center of the fastener is considerably narrower than that of the usual fastener. The cost of the fastener member is considerably reduced because for a given size of the interlocking devices only about half as much material will be required. This is a considerable factor in thecost of fasteners, especially-when they are made from some of the plastics. It will be seen that my improved fastener in addition While I have shown and described in this application one embodiment and a modification which my invention may assume in practice, this embodiment and modification are merely for the purposes of illustration and description and other forms may be devised within the scope of my invention as set forthin the appended claims.
